Description

Technical Field

[0001] This utility model relates to the field of diode manufacturing technology, specifically a diode lead cutting machine. Background Technology

[0002] A diode is an electronic component with unidirectional conductivity, consisting of a PN junction, corresponding electrode leads, and a casing. It has two electrodes, an anode and a cathode. When the anode potential is higher than the cathode potential, the diode conducts, allowing current to flow; conversely, it is cut off, with almost no current flowing through it. There are various types of diodes, such as rectifier diodes used to convert alternating current to direct current, Zener diodes to stabilize voltage, and light-emitting diodes (LEDs) to emit light. Diodes are widely used in electronic circuits, performing functions such as rectification, detection, limiting, and voltage regulation, and are one of the fundamental components in various complex circuits.

[0003] In diode manufacturing, a lead cutting machine is needed to cut off the longer leads of the diode. However, existing lead cutting machines are large in size, have a complex structure, and have high production and usage costs. Furthermore, they lack corresponding fixing measures, which makes the diode prone to displacement when cutting the leads, thus affecting the diode yield.

[0004] To address this, a diode lead cutting machine is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a diode lead cutting machine.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A diode lead cutting machine, comprising:

[0008] Workbench;

[0009] The bottom of the workbench is fixed with a mounting base;

[0010] An L-shaped seat is fixed to the outer wall of the workbench. A hydraulic cylinder is installed on the top of the L-shaped seat. One end of the hydraulic cylinder passes through the L-shaped seat and is fixed with a connecting plate. A ring-shaped cutting blade is fixed to the bottom of the connecting plate.

[0011] The top of the workbench is fixed with an annular seat, and the top of the annular seat is provided with an annular pressure member;

[0012] The annular seat and the annular pressure member each have multiple placement holes at their opposite ends;

[0013] A diode body is placed in each of the multiple placement holes, and a lead body is installed at one end of the diode body.

[0014] Preferably, the top of the workbench has a passageway.

[0015] Preferably, a receiving ring is fixed to the inner wall of the annular seat, and a placement ring for placing the pin body is fixed to the top of the receiving ring.

[0016] Preferably, a movable strip is fixed to the outer wall of the annular pressing member, and a toothed groove is formed on the outer wall of the movable strip. A limit strip is fixed to the top of the worktable, and a movable groove is formed on the outer wall of the limit strip. The movable strip is movably disposed inside the movable groove. A connecting ear is fixed to the outer wall of the limit strip, and a motor is installed on the outer wall of the connecting ear. The output end of the motor passes through the connecting ear and is fixed with a gear that meshes with the toothed groove.

[0017] Preferably, the movable groove is provided with a sliding groove, a slider is installed in the sliding groove, and the moving bar is fixed to one end of the slider.

[0018] Preferably, the placement hole of the annular seat and the placement hole of the annular pressing member are respectively provided with a first soft pad and a second soft pad.

[0019] Preferably, a receiving tray is placed on top of the mounting base.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] In this invention, both the annular seat and the annular pressing component are annular in shape, which greatly reduces the overall footprint and makes the overall structure simpler. Furthermore, most of the components are common mechanical parts, thus reducing overall production and usage costs. When cutting off the diode's leads, the diode is first placed inside the placement hole of the annular seat. Then, the motor is started, driving the gear to rotate. Since the gear meshes with the toothed grooves on the moving bar, the gear, when rotating, will work with the toothed grooves to move the moving bar and the annular pressing component downwards. Once the annular pressing component contacts the annular seat, the diode is fixed in the placement holes of the annular seat and the annular pressing component. Therefore, this invention can fix the diode, preventing it from shifting when the leads are cut off, thereby improving the yield rate of the diode. Attached Figure Description

[0027] 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.

[0028] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0029] Example 1:

[0030] Please see Figure 1-4 This utility model provides a technical solution: To achieve the above objectives, this utility model provides the following technical solution: A diode lead cutting machine, comprising: a workbench 1; a mounting base 2 fixed to the bottom of the workbench 1; an L-shaped base 4 fixed to the outer wall of the workbench 1, a hydraulic cylinder 5 mounted on the top of the L-shaped base 4, one end of the hydraulic cylinder 5 passing through the L-shaped base 4 and fixed with a connecting plate 6, and a ring-shaped cutting blade 7 fixed to the bottom of the connecting plate 6; a ring-shaped base 8 fixed to the top of the workbench 1, and a ring-shaped pressing member 9 provided on the top of the ring-shaped base 8; multiple placement holes are provided at the opposite ends of the ring-shaped base 8 and the ring-shaped pressing member 9; diode bodies 11 are placed in the multiple placement holes, and lead bodies 12 are mounted on one end of the diode body 11; the top of the workbench 1 has... There is a channel 10. A receiving ring 13 is fixed to the inner wall of the annular seat 8. A placement ring 14 for placing the pin body 12 is fixed to the top of the receiving ring 13. A moving strip 19 is fixed to the outer wall of the annular pressure piece 9. The outer wall of the moving strip 19 has a toothed groove 20. A limit strip 17 is fixed to the top of the worktable 1. The outer wall of the limit strip 17 has a movable groove 18. The moving strip 19 is movably disposed inside the movable groove 18. A connecting ear 21 is fixed to the outer wall of the limit strip 17. A motor 22 is installed on the outer wall of the connecting ear 21. The output end of the motor 22 passes through the connecting ear 21 and is fixed with a gear 23 that meshes with the toothed groove 20. A sliding groove 24 is opened in the movable groove 18. A slider 25 is installed in the sliding groove 24. The moving strip 19 is fixed to one end of the slider 25.

[0031] Specifically, the annular seat 8 and the annular pressing member 9 in this utility model are both annular in shape, which greatly reduces the overall footprint and makes the overall structure simpler. Moreover, most of the common mechanical parts are used, thereby reducing the overall production and use costs. When cutting off the lead body 12 of the diode body 11, the diode body 11 is first placed inside the placement hole of the annular seat 8. Then, by starting the motor 22, the motor 22 drives the gear 23 to rotate. Since the gear 23 meshes with the tooth groove 20 on the moving bar 19, the gear 23 will cooperate with the tooth groove 20 to drive the moving bar 19 and the annular pressing member 9 to move downward when rotating. After the annular pressing member 9 contacts the annular seat 8, the diode body 11 can be fixed in the placement hole of the annular seat 8 and the placement hole of the annular pressing member 9. Therefore, this utility model can fix the diode body 11 so that the diode body 11 will not shift when the lead body 12 of the diode body 11 is cut off, thereby improving the yield of the diode body 11.

[0032] Example 2:

[0033] Please see Figure 1 , 3 4. This utility model provides a technical solution: a diode lead cutting machine, in which a first soft pad 16 and a second soft pad 15 are respectively provided in the placement hole of the annular seat 8 and the placement hole of the annular pressing member 9, and a receiving tray 3 is placed on the top of the mounting base 2.

[0034] Specifically, by providing a first soft pad 16 and a second soft pad 15 in the placement holes of the annular seat 8 and the annular pressing member 9 respectively, the cooperation of the first soft pad 16 and the second soft pad 15 can prevent the annular seat 8 and the annular pressing member 9 from damaging the diode body 11, thereby improving the safety of the diode body 11.

[0035] In conjunction with Embodiment 1, the residue after the pin body 12 is cut off will fall into the receiving tray 3 through the channel 10, making it easier to clean the residue later and making it more convenient to use.

[0036] Working principle:

[0037] First, the worker uses mounting base 2 to install workbench 1 and L-shaped base 4 into the designated area. Then, the worker places the diode body 11 to be cut into the placement hole of annular base 8. The worker then starts motor 22 on the outer wall of connecting lug 21. Motor 22 drives gear 23 to work. Since gear 23 meshes with moving bar 19 through tooth groove 20, gear 23 drives moving bar 19 to move within the movable groove 18 of limit bar 17. Moving bar 19 drives annular pressing member 9 to move downward. After annular pressing member 9 contacts annular base 8, diode body 11 is fixed in the placement hole of annular base 8 and the placement hole of annular pressing member 9. During this process, the downward movement path of annular pressing member 9 can be limited by the cooperation of sliding groove 24 and slider 25. The positioning of the diode body 11 is improved to prevent it from shifting. Then, the hydraulic cylinder 5 is activated, which drives the connecting plate 6 and the annular cutting blade 7 to move down. With the cooperation of the annular cutting blade 7, the receiving ring 13, and the placement ring 14, the lead body 12 of the diode body 11 can be cut off. The residue after the lead body 12 is cut off will fall into the receiving plate 3 through the channel 10, making it easy to clean up the residue later. It is convenient to use. Furthermore, by setting the first soft pad 16 and the second soft pad 15 in the placement hole of the annular seat 8 and the placement hole of the annular pressing member 9 respectively, the annular seat 8 and the annular pressing member 9 can avoid damage to the diode body 11, thus improving the safety of the diode body 11.
