    When pressing the mold lead frame plate, the mold lead frame is transported with the mold lead frame direction jig (ZIG) and the conveying part 6 which are designed to be dropped by the timing belt while falling freely on the fixture (ZIG). A mold lead frame alignment position separator (7) equipped with a gate stopper (GATE STOPPER) which temporarily stops the mold lead frame so as to be sequentially arranged in each direction is mounted to one body (BODY) 1. The system which aligns the mold lead frame has a gate stopper at the alignment position divider (7) of the mold lead frame equipped with a gate stopper which temporarily opens and closes one another body (BODY) and sequentially opens and closes it. When opening and closing the stopper in sequence, mold lead frame (8) and mold lead frame through the guide are arranged on the edge of the plate first so that the mold lead frame comes out neatly. It consists of a mold lead frame main alignment part (9) for arranging the product if there is no abnormality, and a mold lead frame auxiliary alignment and container (CARTRIDGE) inserting part (10) for receiving the ordered product and placing it in the loading box again. The mold lead frame loaded in the container (CARTRIDGE) is loaded up to ten containers (CARTRIDGE) so that it is fixed in one container (CARTRIDGE). When the load to be sequentially stacked in alignment with the container automatically increases (CARTRIDGE) elevator vertical drive unit 11 mounted it consists of the automated system.
    2. Operation of the present invention
    In the entire process, the ZIG 12 containing the lead frame molded in the process is placed on the ZIG fixing of the machine and the start button BUTTON is pressed to operate the ZIG fixing cylinder 23. Fix the fixture (ZIG) containing the lead frame, and the up-and-down air cylinder 13 is lowered by the guide of the up and down drive shaft and the support bearing 14. At this time, the air shower unit 22 sprays air for a predetermined time to After cooling the generated heat, press air cylinder (15) is guided by pre-guide shaft and support bearing (5), and press pin mounted on the lower part of plate (PLATE) is operated momentarily to cut mold lead frame plate ( PRESSING) to separate and relax mold lead frame and residual mold resin frame.
    At the same time, the residual mold resin skeleton removal vertical drive air cylinder 7 is lowered to pick up the residual mold resin skeleton with the residual mold resin skeleton removal air finger 19, and the remaining mold resin skeleton removal vertical drive air cylinder 18 is raised. At the same time, after the upper and lower drive air cylinders 13 are raised, the residual mold armature removal motor 20 is started and moved forward by the guidance of the residual mold armature removal drive slide 21 to bring the residual mold armature to the outside of the equipment, and then the finger 19 ), The remaining mold skeleton falls freely to the dropping device (CHUTE) and falls to a certain container, and then the motor 20 moves backwards to its original position. (At this time, the jig 12 containing the molded lead frame is supplied again. When you press the start button, the work completion blinker lights up and the siren sounds and the work continues automatically.)
    When pressing, the mold lead frame falls freely when it falls from the mold resin frame, and falls on the transfer timing belt 26 at a predetermined direction and position by the mold lead frame turning tool (ZIG) 25. Gate stopper (# 1 to # 4) air cylinder 27 descends and the mold lead frame is sequentially moved when the belt is started to drive the timing belt 26 to transfer the mold lead frame on the timing belt 26. Pause
    After that, when the gate stopper air cylinder 27 sequentially discharges the mold lead frame in the same direction, the guide plate guide attached to the driving unit of the lowered guide air cylinder 28 is guided to the link air cylinder 29. If the mold lead frame falls on the link plate operated by the link air link, the link air cylinder 29 operates up and down, and if the mold lead frame is aligned side by side at the edge of the link plate, the link plate If there is no abnormality after the proximity sensor 32, which is a mold lead frame detection sensor, detects the product mounted on the product, the guide air cylinder 28 rises and the link table right and left division air cylinder 30 is divided into left and right sides by the guide of the link table left and right division guide and shaft 31. After the left and right main alignment transfer air cylinder 33 is operated, the mold lead frame is aligned by the left and right alignment main transfer alignment jig (ZIG) 34 attached to the upper side and stopped on the auxiliary alignment plate. A container (35) drags and loads the mold lead frame while the left and right auxiliary alignment feed vertically driven air cylinders and jigs (ZIG) 36 are lowered due to the power transmission to the left and right auxiliary alignment feed ball screws and the guide shaft 37. The product is pushed into the CARTRIDGE) 40 and the left and right auxiliary alignment transfer up and down drive air cylinders and jigs (ZIG) 36 are raised and then returned to their original positions.
    When the entire operation is performed by the given number of times left and right, and each mold lead frame is loaded in the left and right container (CARTRIDGE) 40, the left and right elevator vertical drive motor 38 transmits power to the elevator vertical drive ball screw and guide shaft. With the guidance, ascending and repeating step by step is completed, and each row interval (STEP) of each of the left and right elevators is completed, and after one cycle of the equipment, the operator arranges and loads the mold lead frame (CARTRIDGE). The mold lead frame is automatically supplied by removing the (29) one by one and inserting the container (CARTRIDGE) 40 of the automatic feeding device of the next process.
    If the container (CARTRIDGE) 40 on the elevator is completely removed, the left and right up and down driving elevator is automatically lowered to its original position.
    At this time, if the lead lid frame is completely aligned / loaded in one container (4O), the worker removes the product from time to time, puts it into the next process, and inserts the empty cartridge again. The system of the present invention is constructed to face toward.
    Therefore, the present invention, which automates the reduction of production efficiency and the stability of product quality in manually pressing and arranging mold lead frames, improves productivity, reduces manufacturing costs, and improves product quality in many mold lead frame production industries. I think it can make a big contribution to quality improvement.
    According to the present invention, most of the manufacturers of mold lead frames currently work with their fingers to align and separate lead frames and mold skeletons by hand from the mold equipment. Economic difficulties due to manpower investment, deterioration of product quality and productivity decrease due to worker's change resulted in the improvement, and the idea was conceived, and it was conceived by automating the mold lead frame pressing and alignment made by hand. Productivity is doubled than manual work, and the products from two mold equipments can be digested in one equipment of the present invention, reducing labor costs and stabilization of product quality by reducing manpower separate from pressing and alignment. Due to the qualitative improvement, I can be sure that my manufacturer will gain an international competitive edge when applying the invention.
    [Application and usability of the invention]
    The present invention is an automatic equipment for the process of manufacturing the mold lead frame in the semiconductor industry. When the present invention is applied even when manufacturing another mold lead frame, the automation is easily performed and additionally applied to the unit line and the whole line. Its usefulness is excellent.
