Description

Technical Field

[0001] This utility model relates to the field of capacitor lead cutting technology, and in particular to a capacitor lead cutting device. Background Technology

[0002] Two conductors placed close together, with a non-conductive insulating medium sandwiched between them, constitute a capacitor. When a voltage is applied between the two plates of a capacitor, it stores electrical charge. The capacitance of a capacitor is numerically equal to the ratio of the charge on one conducting plate to the voltage between the two plates. Capacitors need to have their leads cut off during elongation.

[0003] A search revealed that patent CN221158440U discloses a capacitor lead cutting device; however, this capacitor lead cutting device has the following shortcomings in use:

[0004] In use, the capacitor is placed in the placement frame, and the leads are located in the groove and cut with a cutter. However, capacitors come in different sizes, and if they are larger than the placement frame, they are restricted and difficult to cut, which is inconvenient. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where capacitors are placed within a frame and their leads are located in grooves for cutting. However, capacitors vary in size, and if a capacitor is larger than the frame, the cutting process becomes restrictive and inconvenient. Therefore, this invention provides a capacitor lead cutting device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A capacitor lead cutting device includes a machine base. Two fixed plates are fixedly mounted on the top of the machine base. A first electric push rod is fixedly mounted on one side of each of the two fixed plates. The telescopic portion of the first electric push rod passes through the fixed plate. A connecting plate and a stop plate are respectively fixedly mounted on the telescopic portions of the two first electric push rods. A blade holder is fixedly mounted on one side of the connecting plate. A blade for cutting leads is fixed to one side of the blade holder by bolts. A placement frame is provided on the machine base, consisting of two L-shaped clamps. An adjustment mechanism is provided on the machine base, which can adjust the size of capacitors of different sizes that need to be cut.

[0008] In order to push out the capacitor after the leads have been cut, the clamp also includes an ejection mechanism, which can push the capacitor out between the two clamps.

[0009] In one possible design, the adjustment mechanism includes a housing, a motor, two connecting brackets, and a bidirectional lead screw. The top of the housing is slidably connected to the top of the machine base. One side of the motor is fixedly connected to one side of the housing. One end of the bidirectional lead screw is rotatably connected to the inner wall of one side of the housing. The output end of the motor passes through one side of the housing and is fixedly connected to the other end of the bidirectional lead screw. Two moving blocks are slidably connected to the inner wall of one side of the housing. A lead screw nut is embedded in one side of each moving block and is threadedly connected to the bidirectional lead screw. The connecting brackets are U-shaped. One end of each connecting bracket is fixedly connected to one side of the two moving blocks. The bottoms of both clamping plates are slidably connected to the top of the housing. The other end of each connecting bracket is fixedly connected to one side of the clamping plate.

[0010] In one possible design, the ejection mechanism includes a second electric push rod and a push plate. The push plate is T-shaped, and one of the clamping plates has a receiving groove on one inner wall for accommodating the push plate. One end of the second electric push rod is fixedly connected to one side of the clamping plate, and the telescopic part of the second electric push rod passes through one side of the clamping plate and is fixedly connected to one side of the push plate.

[0011] In one possible design, a short plate is fixedly installed on the top of the machine tool, and a third electric push rod for adjusting the length of the cut-off pin is fixedly installed on one side of the short plate. The telescopic part of the third electric push rod is fixedly installed with a frame, and the two ends of the frame are respectively fixedly connected to the two sides of the box.

[0012] In one possible design, the top side of the machine tool has an inclined groove to facilitate the discharge of the cut-off pins, and a concave plate is fixedly installed on one side of the machine tool. The concave plate is concave in shape, and a collection box for collecting the cut-off pins is placed inside the concave plate.

[0013] In one possible design, a dustproof curtain for protecting the bidirectional lead screw is fixedly installed on one side of the housing.

[0014] In one possible design, two guide rods are fixedly installed on the opposite sides of the connecting plate and the abutment plate. A movable hole is provided on the fixed plate, and the outer side of the guide rod is slidably connected to the inner wall of the movable hole.

[0015] In this application, during use, firstly, adjust the distance between the two clamping plates according to the size of the capacitor. Start the motor to drive the bidirectional lead screw to rotate, causing the two moving blocks to move in opposite directions. The moving blocks are linked to the clamping plates through the U-shaped connecting frame, so that the distance between the two L-shaped clamping plates matches the width of the capacitor. Place the capacitor into the placement frame formed by the clamping plates (fitting against the inner wall of one side of the clamping plate), and position the capacitor leads in the gap between the two clamping plates (leads facing the blade). If it is necessary to fix the capacitor, the clamping plates can be clamped by driving the motor. Start the third electric push rod. The telescopic part of the third electric push rod extends and retracts, causing the frame to move, which in turn causes the entire box to move back and forth. When the box moves, the clamping plates and the capacitor move synchronously. Adjust the distance of the lead extending beyond the blade (i.e., the cutting length). Start the two first electric push rods. The connecting plate drives the blade holder to perform the cutting action. The baffle plate extends synchronously to form a supporting reaction force. Through the cooperation of the blade and the baffle plate, the lead is cut off. The cut lead slides through the inclined groove on the machine platform into the collection box in the concave plate for further processing. Collect the capacitor, then start the motor. The motor reverses, causing the clamping plates to slightly move away from both sides of the capacitor. Then, start the second electric push rod. The telescopic part of the second electric push rod retracts, and the telescopic part drives the push plate to move. The push plate pushes the capacitor to move, making the capacitor move away from the two clamping plates for easy removal. The setting of the shielding curtain can protect the bidirectional lead screw from dust (when the connecting frame moves to a certain position, the connecting frame will lift the shielding curtain; when it does not move, it will be blocked by the shielding curtain, which is composed of multiple strips). The shielding curtain (i.e., the door curtain) can be made of PVC or fabric. Of course, the specific material can be selected according to actual needs. The material, type, and specifications of the lead screw can be selected according to actual needs. The material, type, and specifications of the bidirectional lead screw can be selected according to actual needs. The type of motor can be a stepper motor, and the specific type can be selected according to actual needs. It should be noted that the motor, the first electric push rod, the second electric push rod, and the third electric push rod need to be controlled by an external controller and powered by an external power supply during use.

[0016] The beneficial effects of this utility model are as follows:

[0017] In this utility model, the capacitor lead cutting device, through an adjustment mechanism, uses a motor-driven bidirectional lead screw to link with a moving block to achieve adaptive adjustment of the spacing between two L-shaped clamps. It is compatible with capacitors of different sizes, solves the limitations of traditional fixed frames, improves the versatility of the equipment, and reduces the time cost of changing tooling.

[0018] In this utility model, the capacitor lead cutting device uses a push-out mechanism, where a second electric push rod drives a T-shaped push plate to push the cut capacitor out of the clamping plate for easy removal.

[0019] In this invention, the spacing between the two L-shaped clamps can be adaptively adjusted through the adjustment mechanism, which is compatible with capacitors of different sizes, solves the limitations of traditional fixed frames, improves the versatility of the equipment, and reduces the time cost of changing tooling. The ejection mechanism can push the cut capacitor out of the clamps for easy removal. 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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Reference Figure 1-4A lead-cutting device includes a machine base 1, a lead-cutting mechanism, an adjustment mechanism, an ejection mechanism, a lead-cutting length adjustment mechanism, and a lead-collecting mechanism. These components work together to cut the leads of capacitors of different sizes and collect the cut leads. The machine base 1 comprises a fixed plate 8, a first electric push rod 6, a connecting plate 9, a stop plate 13, a knife holder 10, and a blade 12. Two fixed plates 8 are fixedly mounted on the top of the machine base 1. A first electric push rod 6 is fixedly mounted on one side of each fixed plate 8, with its telescopic portion penetrating through the fixed plate 8. The telescopic portions of the two first electric push rods 6 are fixedly connected to the connecting plate 9 and the stop plate 13, respectively. A knife holder 10 is fixedly mounted on one side of the connecting plate 9, and a blade 12 for lead cutting is bolted to one side of the knife holder 10.

[0028] During the lead-cutting operation, the capacitor is placed in a placement frame consisting of two clamping plates 14. Then, the two first electric push rods 6 are activated to extend and retract synchronously, causing the connecting plate 9 and the stop plate 13 to move closer to the capacitor. When the blade 12 moves to the appropriate position, it cuts the capacitor leads.

[0029] The adjustment mechanism includes a housing 2, a motor 17, two connecting brackets 18, and a bidirectional lead screw 15. The top of the housing 2 is slidably connected to the top of the machine base 1. The motor 17 is fixedly mounted on one side of the housing 2. One end of the bidirectional lead screw 15 is rotatably connected to the inner wall of one side of the housing 2, and the output end of the motor 17 passes through one side of the housing 2 and is fixedly connected to the other end of the bidirectional lead screw 15. Two moving blocks 16 are slidably connected to the inner wall of one side of the housing 2. A lead screw nut is embedded in one side of each moving block 16, and the lead screw nut is threadedly connected to the bidirectional lead screw 15. The connecting brackets 18 are U-shaped. One end of each connecting bracket 18 is fixedly connected to one side of the two moving blocks 16. The bottoms of the two clamping plates 14 are slidably connected to the top of the housing 2, and the other end of each connecting bracket 18 is fixedly connected to one side of the clamping plate 14.

[0030] When it is necessary to cut leads for capacitors of different sizes, motor 17 is started, which drives the bidirectional lead screw 15 to rotate. Since the bidirectional lead screw 15 is threadedly connected to the lead screw nut on the moving block 16, and the moving block 16 is slidably connected to the inner wall of one side of the housing 2, the rotation of the bidirectional lead screw 15 will cause the two moving blocks 16 to move closer or further apart along the axial direction of the bidirectional lead screw 15. The movement of the moving blocks 16, through the connecting frame 18, causes the two clamping plates 14 to slide on the top of the housing 2, thereby adjusting the distance between the two clamping plates 14 to accommodate capacitors of different sizes.

[0031] The ejection mechanism includes a second electric push rod 19 and a push plate 20. The push plate 20 is T-shaped, and one of the clamping plates 14 has a receiving groove on one side inner wall for accommodating the push plate 20. One end of the second electric push rod 19 is fixedly connected to one side of the clamping plate 14, and the telescopic part of the second electric push rod 19 passes through one side of the clamping plate 14 and is fixedly connected to one side of the push plate 20.

[0032] After the capacitor leads are cut off, the second electric push rod 19 is activated. The telescopic part of the second electric push rod 19 retracts, pulling the push plate 20 to push out the capacitor located between the two clamping plates 14, making it easier to remove the capacitor after the leads are cut off.

[0033] This application is used in the field of capacitor lead cutting, but it can also be used in other fields applicable to this application.

[0034] Example 2

[0035] refer to Figure 1-4 An improvement based on Embodiment 1: A capacitor lead cutting device, which is used in the field of capacitor lead cutting.

[0036] A short plate is fixedly installed on the top of the machine base 1. A third electric push rod 21 for adjusting the length of the cut-off pin is fixedly installed on one side of the short plate. A frame 3 is fixedly installed on the telescopic part of the third electric push rod 21. The two ends of the frame 3 are fixedly connected to the two sides of the box body 2 respectively.

[0037] When it is necessary to adjust the length of the cut-off pin, the third electric push rod 21 is activated. The telescopic part of the third electric push rod 21 extends and retracts, driving the frame 3 to move. The movement of the frame 3 in turn causes the box 2 to slide on the top of the machine base 1, thereby changing the distance between the blade 12 and the capacitor pin, and realizing the adjustment of the cut-off pin length.

[0038] A sloping groove 11 is provided on one side of the top of the machine base 1 to facilitate the discharge of the cut-off pins. A concave plate 4 is fixedly provided on one side of the machine base 1. The concave plate 4 is concave in shape, and a collection box 5 for collecting the cut-off pins is placed inside the concave plate 4.

[0039] During the lead cutting process, the cut leads slide down the inclined groove 11 into the collection box 5, achieving automatic collection of the cut leads. When the collection box 5 is full of leads, it can be removed from the concave plate 4 for cleaning or subsequent processing.

[0040] Two guide rods 7 are fixedly installed on the opposite sides of the connecting plate 9 and the abutment plate 13. A movable hole is provided on the fixed plate 8, and the outer side of the guide rod 7 is slidably connected to the inner wall of the movable hole. The function of the guide rods 7 is to guide the movement of the connecting plate 9 and the abutment plate 13, ensuring their stability during movement and making the cutting operation more accurate.

[0041] A dustproof curtain is fixedly installed on one side of the housing 2 to prevent dust and other impurities from entering the housing 2 and adhering to the bidirectional lead screw 15, thus affecting the normal rotation of the bidirectional lead screw 15 and the adjustment accuracy of the adjustment mechanism.

[0042] However, as is well known to those skilled in the art, the working principles and wiring methods of the motor 17, the first electric push rod 6, the second electric push rod 19, and the third electric push rod 21 are commonplace and belong to conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0043] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
