Description

Technical Field

[0001] This utility model relates to the field of diode processing technology, specifically a stamping machine for diode production. Background Technology

[0002] A diode is an electronic device made of semiconductor materials (silicon, selenium, germanium, etc.). Diode processing involves cutting and bending the leads to better adapt to different electrical devices, allowing for automated cutting and bending. Therefore, automated stamping machines are needed for this automated process.

[0003] In conventional diode processing, stamping machines use a stamping cylinder to move the stamping box downwards during the cutting and stamping process. When the stamping box, carrying the stamping cutter, moves above the diode, the stamping cutter cuts and stamps the diode leads. When the cutting distance of the diode leads needs to be adjusted, it is necessary to manually adjust the stamping cutter to the appropriate distance before the next cutting and stamping operation. This requires frequent manual adjustment of the stamping cutter, which is inconvenient. Therefore, a new stamping machine for diode production is proposed to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a stamping machine for diode production, which solves the problem that when the stamping and cutting distance of diode leads needs to be adjusted, the stamping cutter must be manually adjusted to a suitable distance before the next stamping and cutting, which requires frequent manual adjustment of the stamping cutter and is inconvenient to operate.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a stamping machine for diode production, including a worktable, a fixed frame fixedly connected to the upper surface of the worktable, a stamping cylinder fixedly connected to the top of the fixed frame, a stamping box fixedly connected to the bottom of the stamping cylinder, a square groove opened at the bottom of the inner wall of the stamping box to facilitate stamping by the stamping cutter, two scrap boxes fixedly connected to the center of the upper surface of the worktable, and a mold base fixedly connected between the two scrap boxes;

[0008] The stamping box is equipped with a movable stamping device and a fixed device.

[0009] The mobile stamping device includes a motor, which is fixedly connected to the bottom of the inner wall of the stamping box. The output end of the motor is fixedly connected to a rotating shaft, and two first bevel gears are fixedly connected to the outer surface of the rotating shaft.

[0010] Preferably, the mobile stamping device further includes a second bevel gear, with the two second bevel gears meshing with the outer surface of the first bevel gear, and a bidirectional screw fixedly connected to the left end of each of the two second bevel gears.

[0011] Preferably, the outer surface of each bidirectional screw is rotatably fitted with a fixing frame, the fixing frame is fixedly connected to the bottom of the stamping box, and the outer surface of each of the two bidirectional screws is threaded with two sliding pins.

[0012] Preferably, the lower ends of the two corresponding sliding columns are fixedly connected with stamping cutters, which pass through square grooves.

[0013] Preferably, the fixing device includes a telescopic rod, which is fixedly connected to the top of the inner wall of the stamping box. A fixing plate is fixedly connected to the output end of the telescopic rod. A spring is fixedly connected between the fixing plate and the stamping box. The spring is slidably sleeved with the telescopic rod. A rubber pad is fixedly connected to the bottom of the fixing plate.

[0014] Preferably, the fixing plate does not contact the bidirectional screw, so as to avoid the movement of the fixing plate affecting the rotation of the bidirectional screw.

[0015] Preferably, the gap between the two stamping cutters is larger than the size of the fixing plate, which facilitates the fixing of the diode by the rubber pad.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a stamping machine for diode production, which has the following advantages:

[0018] 1. This diode production stamping machine uses a bidirectional screw, which drives the first bevel gear to rotate via a motor. This causes the second bevel gear to drive the bidirectional screw to rotate in both directions. The bidirectional screw's rotation in both directions moves the stamping cutter left and right to adjust the stamping distance. This allows for adjustment of the stamping and shearing distance of the diode leads by the stamping cutter. It is easy to operate and highly practical.

[0019] 2. The stamping machine used for diode production uses a fixed device to fix the diode by pressing it downward with a rubber pad. When the stamping cylinder moves the stamping box downward, the spring is in an extended state. As the cylinder extends, the telescopic rod retracts and the spring is compressed. At this time, both the telescopic rod and the spring are in a stable state. The rubber pad provides buffer protection for the diode while pressing it, preventing the diode pins from deforming due to the pressure. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 This utility model provides a new technical solution: a stamping machine for diode production, including a workbench 1, a fixed frame 2 fixedly connected to the upper surface of the workbench 1, a stamping cylinder 3 fixedly connected to the top of the fixed frame 2, a stamping box 4 fixedly connected to the bottom of the stamping cylinder 3, a square groove 19 opened at the bottom of the inner wall of the stamping box 4 to facilitate stamping by the stamping cutter 18, and two scrap boxes 5 fixedly connected to the center of the upper surface of the workbench 1, and a mold base 6 fixedly connected between the two scrap boxes 5.

[0027] The stamping box 4 is equipped with a movable stamping device and a fixed device.

[0028] Furthermore, the mobile stamping device includes a motor 11, which is fixedly connected to the bottom of the inner wall of the stamping box 4. The output end of the motor 11 is fixedly connected to a rotating shaft 12. Two first bevel gears 13 are fixedly connected to the outer surface of the rotating shaft 12. The outer surfaces of the two first bevel gears 13 are respectively meshed with second bevel gears 14. The left ends of the two second bevel gears 14 are fixedly connected to bidirectional screws 15.

[0029] Among them, the outer surfaces of the two bidirectional screws 15 are rotatably sleeved with a fixing frame 16, the fixing frame 16 is fixedly connected to the bottom of the stamping box 4, and the outer surfaces of the two bidirectional screws 15 are respectively threaded with two sliding columns 17.

[0030] Among them, the lower ends of the two corresponding sliding columns 17 are fixedly connected to a stamping cutter 18, which passes through the square groove 19.

[0031] Furthermore, the fixing device includes a telescopic rod 7, which is fixedly connected to the top of the inner wall of the stamping box 4. A fixing plate 8 is fixedly connected to the output end of the telescopic rod 7. A spring 10 is fixedly connected between the fixing plate 8 and the stamping box 4. The spring 10 is slidably sleeved with the telescopic rod 7. A rubber pad 9 is fixedly connected to the bottom of the fixing plate 8.

[0032] Furthermore, when using this device, the operator places the diode to be stamped in the groove on the mold base 6. The operator starts the stamping cylinder 3, and the output end of the stamping cylinder 3 extends downward, causing the stamping box 4 to move downward until the stamping box 4 moves down above the mold base 6. Then, the operator starts the telescopic rod 7, and the output end of the telescopic rod 7 moves downward, causing the fixing plate 8 to move downward. The movement of the fixing plate 8 causes the rubber pad 9 to move downward until the rubber pad 9 touches the diode on the mold base 6. The rubber pad 9 squeezes the diode downward. Since the bottom of the rubber pad 9 has a slot larger than the diode, it can be used to fix the diode. When the stamping cylinder 3 drives the stamping box 4 to move downward, the spring 10 is in an extended state. As the stamping cylinder 3 extends, the telescopic rod 7 retracts and the spring 10 is compressed. At this time, the telescopic rod 7 and the spring 10 are in a stable state. The rubber pad 9 provides buffer protection for the diode while squeezing it, preventing the diode pin from deforming due to squeezing.

[0033] When it is necessary to stamp and cut diode leads of different lengths, motor 11 is started. The output of motor 11 drives shaft 12 to rotate. The rotation of shaft 12 drives two first bevel gears 13 sleeved on the outer surface of shaft 12 to rotate. The rotation of the first bevel gears 13 drives two second bevel gears 14 meshing on their outer surfaces to rotate. The rotation of the second bevel gears 14 drives two bidirectional screws 15 to rotate, causing the bidirectional screws 15 to rotate within the fixed frame 16. The rotation of the bidirectional screws 15 drives the sliding pins 17 sleeved on their outer surfaces to rotate. Since the threads of the bidirectional screws 15 rotate in opposite directions, the bidirectional screws 15, along with the rotating sliding pins 17, rotate in opposite directions within the fixed frame 16. The movement of the sliding pins 17 drives... The stamping cutter 18 moves, and due to the restriction of the sliding column 17 by the stamping cutter 18, the sliding column 17 carries the stamping cutter 18 to slide on the bidirectional screw 15. When the bidirectional screw 15 rotates forward, the bidirectional screw 15 carries the two stamping cutters 18 to move closer to each other. When the bidirectional screw 15 rotates in reverse, the bidirectional screw 15 carries the two stamping cutters 18 to move away from each other. By rotating the bidirectional screw 15 forward and backward, the stamping distance is adjusted by driving the stamping cutter 18 to move left and right. This realizes the adjustment of the stamping and shearing distance of the stamping cutter 18 on the diode pins. It is easy to operate and has strong applicability. The debris cut off by the stamping cutter 18 falls directly into the debris boxes 5 on both sides of the mold base 6, which is convenient for collecting the debris of the diode pins.
