Description

Technical Field

[0001] This invention relates to the technical field of electronic device manufacturing, and in particular to a heat shrink tubing forming machine for electronic devices. Background Technology

[0002] Currently, some electronic components (such as capacitors) require precise fitting into heat shrink tubing. Existing technology typically involves manual operation: the electronic component is placed into a fixture, a small section of heat shrink tubing is manually inserted, and then a heat gun is used to firmly wrap the tubing around the component. This manual method is inefficient and cannot achieve consistent quality, failing to meet the demands of high-efficiency, high-quality electronic component production. Summary of the Invention

[0003] The purpose of this invention is to provide a heat shrink tubing forming machine for electronic devices, mainly solving the technical problem of how to automatically apply heat shrink tubing to electronic devices.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] An electronic device heat shrink tubing forming machine includes a frame and a feeding mechanism, a turntable, a loading mechanism, a tubing mechanism, a calibration mechanism, a heat shrinking mechanism, and a unloading mechanism, all connected to the frame.

[0006] The turntable is rotatable relative to the frame, and the turntable is provided with a clamp for clamping electronic devices. When the turntable rotates, it drives the clamp to rotate relative to the frame.

[0007] The feeding mechanism is used to automatically provide electronic devices, and the loading mechanism is located on one side of the feeding mechanism and is used to transfer the electronic devices on the feeding mechanism to the clamps on the turntable;

[0008] The sleeve mechanism, the calibration mechanism, the heat shrink mechanism, and the unloading mechanism are arranged sequentially along the rotation direction of the turntable on one side of the turntable. The sleeve mechanism is used to sleeve the heat shrink sleeve onto the electronic device located on the fixture from top to bottom. The calibration mechanism is used to calibrate the position of the heat shrink sleeve sleeved on the electronic device. The heat shrink mechanism is used to heat shrink the heat shrink sleeve and wrap it around the outer wall of the electronic device. The unloading mechanism is used to unload the electronic device located on the fixture outward to a preset position.

[0009] In the above technical solution, the feeding mechanism includes a base, a tape feeding mechanism, a drive motor, and a turntable;

[0010] The base is connected to the frame. The base is provided with a guide groove for the tape to enter and exit. The tape has multiple holes along its length and is used to attach the pins of electronic devices. The dial wheel has multiple protrusions on its radial outer wall. The dial motor is connected to the base and the dial wheel and is used to drive the dial wheel to rotate. When the dial wheel rotates, the protrusions are embedded in the holes of the tape to drive the tape to move in the guide groove. The movement path of the tape includes a position adjacent to the feeding mechanism.

[0011] The heat shrink tubing forming machine for electronic devices also includes a first cutting mechanism connected to the frame. The first cutting mechanism is located on one side of the dial and is used to cut off the pins of the electronic device so that the pins of the electronic device can be separated from the tape.

[0012] In the above technical solution, the electronic device heat shrink tubing forming machine further includes a second cutting mechanism connected to the frame. The heat shrink mechanism, the second cutting mechanism and the feeding mechanism are arranged sequentially on one side of the turntable along the rotation direction of the turntable. The second cutting mechanism is used to cut the pins on the electronic device to a preset length.

[0013] In the above technical solution, the clamp includes a base, a telescopic rod, an elastic element, and two clamping blocks;

[0014] The base is connected to the turntable, the telescopic rod slides and extends relative to the base, the two clamping blocks are rotatably connected to the base, and both clamping blocks are confined to the telescopic rod. The elastic element connects the base and the telescopic rod. The telescopic rod is subjected to the elastic force of the elastic element, causing the two clamping blocks to move closer together and be in a clamping state. When the two clamping blocks are in the clamping state, they are joined together to form a positioning part and a clamping groove. The top surface of the positioning part is a support surface for supporting the electronic device. The positioning part has a downwardly extending positioning hole, which is used to limit the position of the pins of the electronic device. The clamping groove is used to clamp the electronic device with heat shrink tubing already on it, and the clamping groove extends downward through the clamping block.

[0015] In the above technical solution, the electronic device heat shrink tubing forming machine further includes a material transfer mechanism connected to the frame. The heat shrink mechanism, the material transfer mechanism and the second cutting mechanism are arranged sequentially on one side of the turntable along the rotation direction of the turntable. The material transfer mechanism is used to move the electronic device located on the positioning part of the fixture into the clamping slot of the fixture.

[0016] In the above technical solution, the electronic device heat shrink tubing forming machine further includes an opening and clamping mechanism connected to the frame. The opening and clamping mechanism is used to push the telescopic rod to compress the elastic element and switch the two clamping blocks from the clamping state to the open state.

[0017] Before the clamp receives electronic devices from the loading mechanism, when the clamp rotates to the adjacent position of the transfer mechanism, and when the clamp rotates to the unloading mechanism, the clamp must be driven by the opening mechanism to switch from the clamping state to the open state.

[0018] In the above technical solution, the sleeve mechanism includes a frame, a feeding tray, a first driver, a sleeve module, a first gripper, a shaft, a third driver, and a cutter.

[0019] The frame is connected to the machine frame, the feeding tray is rotatably connected to the frame, the feeding tray is provided with an annular groove, the annular groove is used for winding the heat shrink tubing in a flat state; the length direction of the shaft is vertical and is used to open the inner hole of the heat shrink tubing.

[0020] The sleeve module further includes a connected second driver and a second gripper, with the second gripper positioned above the first gripper. The second gripper is used to grip the heat shrink sleeve wound outward from the feed tray, and the second driver is used to drive the second gripper to rise or fall.

[0021] Both the first driver and the third driver are connected to the frame. The first driver is connected to the first gripper and the sleeve module respectively. The first driver is used to drive the first gripper and the sleeve module to rise or fall together. The first gripper is used to simultaneously grip the heat shrink sleeve and the shaft core located inside the heat shrink sleeve. The third driver is connected to the cutter and is used to drive the cutter to extend directly below the shaft core.

[0022] In the above technical solution, the shaft core includes a plug-in part, a hole-expanding part, and a guide part connected sequentially from top to bottom;

[0023] The enlarged portion gradually expands in a tapered shape from the bottom end of the insertion portion to the guide portion. The radial side of the guide portion is a guide surface, which extends downward in a cylindrical shape. The outer dimensions of the guide surface are greater than or equal to the outer dimensions of the outer wall surface of the heat shrink tubing required on the electronic device. When the first gripper simultaneously grips the heat shrink tubing and the shaft core located inside the heat shrink tubing, the first gripper holds the guide surface on the shaft core.

[0024] In the above technical solution, the calibration mechanism includes a fourth driver, a fifth driver, a pressure block, and a push block;

[0025] Both the fourth and fifth drivers are connected to the frame. The fourth driver is connected to the pressure block and is used to drive the pressure block to rise or fall vertically. The falling of the pressure block is used to abut against the top surface of the electronic device so that the pressure block and the support surface together clamp the electronic device. The fifth driver is connected to the push block and is used to drive the push block to rise or fall vertically. The rising of the push block is used to push the heat shrink tubing fitted on the electronic device upward to a predetermined position.

[0026] In the above technical solution, the unloading mechanism includes a sixth driver, an unloading tray, an adhesive application module, and an unloading robot.

[0027] The sixth driver, the adhesive application module, and the unloading robot are all connected to the frame. The adhesive application module is used to apply adhesive to the top surface of the electronic device located in the clamping slot. The top of the unloading tray is provided with a plurality of circumferentially arranged receiving slots. The sixth driver is connected to the unloading tray and is used to drive the unloading tray to rotate. When the unloading tray rotates, any of the receiving slots on the unloading tray can be located directly below the clamping slot. The unloading robot is used to unload at least one of the electronic devices located on the unloading tray to a preset position.

[0028] Compared with the prior art, the electronic device heat shrink tubing forming machine provided by the present invention has at least the following beneficial effects:

[0029] During operation, the feeding mechanism automatically feeds electronic components, and then the loading mechanism moves the electronic components from the feeding mechanism to the fixture on the turntable. Then, the rotation of the turntable moves the fixture sequentially to the adjacent positions of the sleeve mechanism, calibration mechanism, heat shrink mechanism, and unloading mechanism. The sleeve mechanism is used to automatically put the heat shrink tubing onto the electronic components. After the heat shrink tubing is in place, the calibration mechanism calibrates the position of the heat shrink tubing on the electronic components. Then, the heat shrink mechanism blows hot air onto the heat shrink tubing, so that the heat shrink tubing is heated and wraps around the outer wall of the electronic components. Finally, the unloading mechanism unloads the electronic components that have completed the sleeve operation from the fixture to the preset position.

[0030] In summary, this solution can automatically and accurately apply heat shrink tubing to electronic devices, significantly improving the tubing efficiency and ultimately increasing the production efficiency of electronic devices. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0064] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0065] Please refer to the following: Figures 1 to 4This embodiment provides a heat shrink tubing forming machine for electronic devices, including a frame 1 and a feeding mechanism 2, a first cutting mechanism 3, a turntable 4, a loading mechanism 5, a tubing mechanism 6, a calibration mechanism 7, a heat shrinking mechanism 8, a second cutting mechanism 9, and a unloading mechanism 10, all connected to the frame 1. The turntable 4 is driven by a motor, allowing it to rotate relative to the frame 1. A clamp 41 is mounted on the turntable 4. The loading mechanism 5, tubing mechanism 6, calibration mechanism 7, heat shrinking mechanism 8, second cutting mechanism 9, and unloading mechanism 10 are sequentially arranged on one side of the turntable 4 along its rotation direction.

[0066] Specifically, the feeding mechanism 2 uses a tape feeding method to automatically feed electronic components. The tape is used to bond the pins of multiple electronic components. At this time, simply driving the tape to move the electronic components can move them to the required positions. The first lead-cutting mechanism 3 is used to cut off the pins on the electronic components, so that the electronic components can be separated from the tape. After being separated from the tape, the electronic components are placed on the fixture 41 under the drive of the loading mechanism 5. The turntable 4 drives the fixture 41 to rotate, so that the fixture 41 is sequentially moved to the adjacent positions of the sleeve mechanism 6, the calibration mechanism 7, the heat shrinking mechanism 8, the second lead-cutting mechanism 9, and the unloading mechanism 10. The heat shrinking mechanism 6 is used to fit the heat shrink tubing onto the electronic device located on the fixture 41. The calibration mechanism 7 is used to calibrate the position of the heat shrink tubing on the electronic device, so that the position of the heat shrink tubing relative to the electronic device is more accurate. The heat shrinking mechanism 8 shrinks the heat shrink tubing by blowing hot air and makes the heat shrink tubing wrap around the outer wall of the electronic device. The second lead cutting mechanism 9 is used to cut the leads of the electronic device located on the fixture 41 to a preset length. The unloading mechanism 10 is used to unload the electronic device located on the fixture 41 outward to a preset position.

[0067] The electronic device in this embodiment takes a capacitor as an example. The following description, in conjunction with the accompanying drawings, will explain each of the above-mentioned mechanisms in detail.

[0068] Please refer to the following: Figure 5 and Figure 6The feeding mechanism 2 includes a base 21, a tape (not shown in the figure), a drive motor 22, and a turntable 23. The base 21 is fixed to the frame 1 and has a guide groove 211 for the tape to enter and exit. The guide groove 211 preferably extends in a U-shape, so that the direction in which the tape enters the guide groove 211 is opposite to the direction in which it leaves the guide groove 211. The tape has multiple holes along its length. The drive motor... 22 is fixed to the base 21. The dial wheel 23 is connected to the output shaft of the actuating motor 22. The dial wheel 23 has multiple protrusions 231 on its radial outer wall. When the dial wheel 23 rotates under the drive of the actuating motor 22, the protrusions 231 of the dial wheel 23 will be embedded into the holes of the tape, so as to drive the tape to move along the extension direction of the guide groove 211. The movement path of the tape includes the position adjacent to the above-mentioned feeding mechanism 5, so that the feeding mechanism 5 can pick up the capacitor 80 from the tape. The first cutting mechanism 3 cuts off the leads of the capacitor 80 by driving the blade 31 laterally, so that the capacitor 80 and the tape are separated from each other, so that the feeding mechanism 5 can easily pick up the capacitor 80 from the tape. In fact, the cut leads on the capacitor 80 will not fall down. The cut leads on the capacitor 80 will remain on the tape and be sent out as the tape is fed out along the guide groove 211.

[0069] Among them, the feeding mechanism 5 is a conventional two-axis or three-axis picking robot. The structure of the feeding mechanism 5 will not be described in detail here.

[0070] Please refer to the following: Figure 4 , Figures 7 to 9Multiple clamps 41 are fixed on the turntable 4, enabling the aforementioned feeding mechanism 5, sleeve mechanism 6, calibration mechanism 7, heat shrinking mechanism 8, second cutting mechanism 9, and unloading mechanism 10 to operate simultaneously, thereby improving the equipment's working efficiency. Each clamp 41 specifically includes a base 411, a telescopic rod 412, an elastic element 413, and two clamping blocks 414. The base 411 is fixed on the turntable 4, the telescopic rod 412 can slide telescopically relative to the base 411, and both clamping blocks 414 are rotatably connected to the base 411. The telescopic rod 412 has an inclined groove, into which parts of the two clamping blocks 414 are embedded, limiting the clamping blocks 414 on the telescopic rod 412. When the telescopic rod 412 slides telescopically relative to the base 411, it can drive the two clamping blocks 414 to switch between a clamped state and an open state. The elastic element 413 is preferably a spring. The elastic element 413 connects the telescopic rod 412 and the base 411. The telescopic rod 412 is springed open by the elastic force of the elastic element 413, causing the two clamping blocks 414 to move closer to each other and be in the clamping state described above. When the two clamping blocks 414 are in the clamping state, the two clamping blocks 414 are spliced ​​together to form a positioning part 415 and a clamping groove 416. The positioning part 415 is preferably protruding upward relative to the clamping blocks 414. The top surface of the positioning part 415 is a support surface 4151 for supporting the capacitor 80, so that the capacitor 80 can be fitted with a heat shrink sleeve under the support of the support surface 4151. In addition, two downwardly extending positioning holes 4152 are provided on the top of the positioning part 415. These positioning holes 4152 are used to limit the position of the leads of the capacitor 80, so that the capacitor 80 can be firmly placed on the positioning part 415, and the capacitor 80 will not fall over during the sleeve operation. The wall of the clamping groove 416 is used to clamp the capacitor 80 that has been fitted with heat shrink tubing. Furthermore, the clamping groove 416 extends downward through the clamping block 414, so that when the wall of the clamping groove 416 clamps the capacitor 80, the two leads of the capacitor 80 can be exposed downward, so that the leads of the capacitor 80 can be shortened by the subsequent second lead-cutting mechanism 9.

[0071] In practice, after the feeding mechanism 5 takes the capacitor from the feeding mechanism 2, it places it on the positioning part 415 of the fixture 41. Then, the capacitor 80 sequentially completes the processes of fitting the heat-shrink tubing, calibrating the heat-shrink tubing position, and heat-shrinking on the positioning part 415, until it reaches the second cutting mechanism 9, at which point the capacitor 80 needs to be moved from the positioning part 415 to the clamping slot 416. Please refer to [the relevant documentation / reference] for further details. Figure 2 and Figure 3This embodiment also includes a material transfer mechanism 11, which is fixedly connected to the frame 1. The heat shrink mechanism 8, the material transfer mechanism 11, and the second cutting mechanism 9 are arranged sequentially on one side of the turntable 4 along the rotation direction of the turntable 4. The material transfer mechanism 11 is used to move the capacitor located on the positioning part 415 of the clamp 41 to the clamping slot 416 of the clamp 41, so that the second cutting mechanism 9 can cut the lead of the capacitor 80 to a preset length. The material transfer mechanism 11 is a conventional two-axis or three-axis picking robot. The structure of the material transfer mechanism 11 will not be described in detail here.

[0072] As can be seen from the above, the fixture 41 in this embodiment facilitates both the sleeve operation of the capacitor 80 and the lead cutting operation of the capacitor 80. The capacitor 80 does not need to complete the lead cutting operation in other equipment, thereby greatly improving the production efficiency of the capacitor 80.

[0073] Please refer to the following: Figure 3 and Figure 10 This embodiment also includes an opening clamping mechanism 12, which is fixed to the frame 1 via an adapter frame 13. The opening clamping mechanism 12 is located on the side of the clamp 41 closer to the center of the turntable 4. The opening clamping mechanism 12 is preferably a cylinder. The opening clamping mechanism 12 is used to push the telescopic rod 412 to compress the elastic element 413, so that the two clamping blocks 414 switch from the clamped state to the open state. Specifically, when the clamp 41 receives the capacitor 80 from the feeding mechanism 5, when the clamp 41 rotates to the adjacent position of the transfer mechanism 11, and when the clamp 41 rotates to the unloading mechanism 10, the clamp 41 needs to be driven by the opening clamping mechanism 12 to switch from the clamped state to the open state. In other words, there are three clamping mechanisms 12. The first clamping mechanism 12 is responsible for driving the clamp 41 adjacent to the feeding mechanism 5 to open. The second clamping mechanism 12 is responsible for driving the clamp 41 adjacent to the transferring mechanism 11 to open. The third clamping mechanism 12 is responsible for driving the clamp 41 adjacent to the unloading mechanism 10 to open.

[0074] Please refer to the following: Figures 11 to 17 The sleeve mechanism 6 in this embodiment includes a frame 61, a positioning mechanism 62, a feeding tray 63, a first driver 64, a sleeve module 65, a first gripper 66, a shaft core 67, a third driver 68, and a cutter 69. The sleeve module 65 further includes a connected second driver 651 and a second gripper 652. The positioning mechanism 62, the feeding tray 63, the first driver 64, and the third driver 68 are all fixed to the frame 61. The positioning mechanism 62, the first gripper 66, and the second gripper 652 are preferably gripper cylinders, which have the ability to grip or release an object. The first driver 64, the second driver 651, and the third driver 68 are preferably multi-axis cylinders with self-guided operation.

[0075] The positioning mechanism 62 is located on one side of the capacitor 80. When the positioning mechanism 62 is in the clamping state, it clamps the capacitor 80 to correct its position and ensure that the capacitor 80 can be fitted into the heat shrink tubing 90 in the correct position.

[0076] The feeding tray 63 is located at the top and is rotatably connected to the frame 61. The feeding tray 63 is provided with an annular groove 631, and the heat shrink tubing 90 can be wound in the annular groove 631, so that the feeding tray 63 can store a sufficiently long heat shrink tubing 90 to realize the function of automatic feeding of heat shrink tubing 90. It should be noted that when the heat shrink tubing 90 is wound on the feeding tray 63, the heat shrink tubing 90 is in a flat state.

[0077] The first driver 64 is connected to a mounting base 641, and the second driver 651 and the first gripper 66 are fixed on the mounting base 641. The first driver 64 is used to drive the mounting base 641, the entire sleeve module 65 and the first gripper 66 to move up or down together in the vertical direction.

[0078] The second driver 651 is used to drive the second gripper 652 to rise or fall in the vertical direction, and the second gripper 652 is used to grip the heat shrink tubing 90 wound from the feed tray 63.

[0079] The shaft core 67 has its length pointing vertically and is used to open the inner hole of the heat shrink tubing 90. Specifically, the shaft core 67 includes an insertion part 671, an expanding part 672, and a guide part 673 connected sequentially from top to bottom. The insertion part 671 is a needle-like structure extending vertically. The expanding part 672 gradually widens in a tapered shape from the bottom end of the insertion part 671 to the top end of the guide part 673. When the flat heat shrink tubing 90 is inserted into the shaft core 67, the insertion part 671 first inserts into the inner hole of the heat shrink tubing 90, and then the expanding part 672 expands the inner hole of the flat heat shrink tubing 90. Gradually expand outwards until the heat shrink tubing 90 is fitted onto the guide portion 673. At this point, the inner hole of the portion of the heat shrink tubing 90 fitted onto the guide portion 673 is completely expanded in a circular shape. The radially side surface of the guide portion 673 is a guide surface 6731, which extends downwards in a cylindrical shape. The guide surface 6731 is used to allow the heat shrink tubing 90 to slide vertically downwards. Moreover, the outer dimensions of the guide surface 6731 are greater than or equal to the outer wall surface of the tubing required on the capacitor 80 (e.g., ...). Figure 13The dimensions of the wall surface 81 (as referred to) allow the heat shrink tubing 90 to be inserted downwards onto the wall surface 81 of the capacitor 80 along the guide surface 6731. Furthermore, the guide surface 6731 has multiple recessed grooves 6732, which are radially recessed along the guide portion 673 and extend upwards to the tapered wall surface of the enlarged hole portion 672. These grooves reduce the contact area between the heat shrink tubing 90 and the guide surface 6731, thereby reducing the friction between them and making it easier for the heat shrink tubing 90 to be inserted downwards onto the wall surface 81 of the capacitor 80 along the guide surface 6731.

[0080] The first gripper 66 is located directly below the second gripper 652. The first gripper 66 is also used to grip the heat shrink tubing 90 wound from the feed tray 63. Moreover, when the first gripper 66 grips the heat shrink tubing 90, the first gripper 66 also grips the guide surface 6731 of the shaft core 67 inside the heat shrink tubing 90.

[0081] The third driver 68 is connected to the cutter 69. The third driver 68 is used to drive the cutter 69 to move directly below the shaft core 67 and extend between the shaft core 67 and the capacitor 80, so that the cutter 69 can cut the heat shrink sleeve 90 sleeved on the capacitor 80.

[0082] The following describes the working principle of the sleeve mechanism 6 in this embodiment:

[0083] First, the flat heat shrink tubing 90 is pre-wound outward from the feed tray 63, and then the flat heat shrink tubing 90 is inserted downward onto the shaft core 67, so that the shaft core 67 is located inside the heat shrink tubing 90. Figure 14 As shown, guided by the shaft core 67, the heat shrink tubing 90 is expanded from its original flat state to a hollow cylindrical state by the shaft core 67. Then, the first gripper 66 simultaneously clamps the heat shrink tubing 90 and the shaft core 67 located inside the heat shrink tubing 90. Specifically, at this time, the first gripper 66 clamps the guide surface 6731 of the shaft core 67 through the heat shrink tubing 90.

[0084] Then, the first driver 64 drives the entire sleeve module 65 and the first gripper 66 to descend together. The descending height is preferably 1mm. At this time, the bottom surface of the shaft core 67 (i.e. the bottom surface of the guide part 673) will abut against the top surface of the capacitor 80. Then the first gripper 66 is released, and the top surface of the capacitor 80 supports the shaft core 67 to prevent the shaft core 67 from falling downward due to its own weight.

[0085] Immediately afterwards, the second gripper 652 has already gripped the heat shrink tubing 90, and the second driver 651 drives the second gripper 652 to descend. The second gripper 652 grips the heat shrink tubing 90 and descends, so that the heat shrink tubing 90 is gradually inserted into the capacitor 80 along the guide surface 6731 of the shaft core 67.

[0086] When the heat shrink tubing 90 is slid down to the preset length, the first gripper 66 clamps the heat shrink tubing 90 and the guide surface 6731 of the shaft core 67 simultaneously. Then, the first driver 64 drives the tubing module 65 and the first gripper 66 to rise simultaneously, so that the shaft core 67 and the heat shrink tubing 90 rise together with the first gripper 66 a short distance. At this time, the distance that the shaft core 67 rises is preferably 1mm, so that the bottom surface of the shaft core 67 (i.e. the bottom surface of the guide part 673) and the top surface of the capacitor 80 are separated from each other. At this time, the gap between the bottom surface of the shaft core 67 and the top surface of the capacitor 80 is 1mm.

[0087] Finally, the third driver 68 drives the cutter 69 to extend between the shaft core 67 and the capacitor 80. At this time, the cutter 69 cuts the heat shrink tubing 90. Meanwhile, the second gripper 652 has switched from the gripping state to the open state. Furthermore, the second gripper 652 moves upward to the reset position under the drive of the second driver 651, waiting for the next cycle. This completes the function of automatically attaching the tubing to the capacitor 80.

[0088] In fact, the stroke of the first driver 64 controls the gap between the shaft 67 and the capacitor 80 so that the cutter 69 can cut the heat shrink tubing 90 better when the shaft 67 moves upward away from the capacitor 80, while the stroke of the second driver 651 controls the depth to which the heat shrink tubing 90 is inserted into the capacitor 80.

[0089] This section further explains that the sleeve mechanism 6 of this technical solution is more suitable for the automatic sleeve operation of large-diameter heat shrink tubing 90. This is because the wall thickness of large-diameter heat shrink tubing 90 is usually thinner. When the heat shrink tubing 90 is sleeved onto the shaft core 67, the large-diameter heat shrink tubing 90 usually does not completely wrap around the shaft core 67. Under the clamping of the second gripper 652, the large-diameter heat shrink tubing 90 can be easily sleeved onto the capacitor 80 along the guide surface 6731 of the shaft core 67. In other words, the large-diameter heat shrink tubing 90 can slide relatively easily relative to the shaft core 67.

[0090] Please refer to the following: Figure 12 and Figure 14The mounting base 641 is provided with a first limiting groove 6411, which is located directly above the second gripper 652. The first limiting groove 6411 penetrates the mounting base 641. The flat heat shrink tubing 90 wound from the feed tray 63 passes through the first limiting groove 6411 and is fitted onto the shaft core 67. The first limiting groove 6411 is in the shape of a straight line, allowing it to limit the position of the flat heat shrink tubing 90. Furthermore, because... The first limiting groove 6411 is located directly above the second gripper 652. Therefore, when the mounting base 641 moves vertically under the drive of the first driver 64, the mounting base 641 can always straighten the part of the heat shrink sleeve 90 below the first limiting groove 6411, avoiding the problem that the heat shrink sleeve 90 will wobble and thus cannot be stably and vertically inserted into the capacitor 80. That is, the reliability and stability of the heat shrink sleeve 90 being inserted into the capacitor 80 are improved.

[0091] Please refer to the following: Figure 13 and Figure 15 A limiting seat 70 is fixed above the second gripper 652. The limiting seat 70 moves vertically along with the second gripper 652. The limiting seat 70 has a through second limiting groove 701, which is located directly below the first limiting groove 6411. The flat heat shrink tubing 90 wound from the feed tray 63 passes through the first limiting groove 6411 and the second limiting groove 701 in sequence and is then fitted onto the shaft core 67. The second limiting groove 701 is U-shaped and is also used to limit the flat... The position of the heat shrink tubing 90, namely the second limiting groove 701, also prevents the flat heat shrink tubing 90 from swaying. Through the combined action of the first limiting groove 6411 and the second limiting groove 701, a longer section of heat shrink tubing 90 that is straightened in the vertical direction is provided above the second gripper 652. This ensures that the second gripper 652 can reliably hold the heat shrink tubing 90 and slide it down onto the capacitor 80, thereby further improving the reliability and stability of the heat shrink tubing 90 sliding down onto the capacitor 80.

[0092] The bushing mechanism 6 of this technical solution can significantly improve the efficiency of the bushing of capacitor 80, thereby significantly improving the production efficiency of capacitor 80. Moreover, the bushing mechanism 6 of this technical solution also has the advantages of simple structure, low cost and high reliability.

[0093] Please see Figure 18The calibration mechanism 7 includes a fourth actuator 71, a fifth actuator 72, a pressure block 73, and a pusher block 74. The fourth actuator 71 and the fifth actuator 72 are both fixed on the frame 1, and both the fourth actuator 71 and the fifth actuator 72 are preferably cylinders. The fourth actuator 71 is connected to the pressure block 73 and is used to drive the pressure block 73 to rise or fall vertically. The fifth actuator 72 is connected to the pusher block 74 and is used to drive the pusher block 74 to rise or fall vertically. The rising of the pressure block 73 and the falling of the pusher block 74 are both used to avoid the clamp 41 from turning. When the clamp 41 rotates between the pressure block 73 and the pusher block 74, the pressure block 73 first falls and abuts against the top surface of the capacitor 80. That is, the pressure block 73 and the support surface 4151 on the clamp 41 will jointly clamp the capacitor 80 to stabilize the position of the capacitor 80. Then the pusher block 74 moves upward and pushes the heat shrink sleeve 90 upward to a predetermined position to calibrate the position of the heat shrink sleeve 90 on the capacitor 80.

[0094] The heat shrink mechanism 8 in this embodiment is prior art. The heat shrink mechanism 8 uses hot air to blow onto the capacitor 80 located on the positioning part 415 of the clamp 41, causing the heat shrink sleeve 90 to wrap around the outer wall of the capacitor 80. Therefore, this embodiment will not describe the heat shrink mechanism 8 in detail. To improve work efficiency, there are two heat shrink mechanisms 8. By performing two heat shrink operations on the capacitor 80, the simultaneous operation of other mechanisms is not affected.

[0095] Please see Figure 19 The second lead-cutting mechanism 9 includes a fixed base 91, a pressing component 92, a collection box 93, and two lead-cutting modules 94. The fixed base 91 is fixed on the frame 1. The pressing component 92 and the two lead-cutting modules 94 are all connected to the fixed base 91. During operation, the pressing component 92 descends and abuts against the top surface of the capacitor 80 to stabilize the position of the capacitor 80. The two lead-cutting modules 94 shorten the two leads of the capacitor 80 to a preset length by moving closer to each other. The collection box 93 is arranged at the bottom of the fixed base 91 and is used to collect the leads that have been cut off from the capacitor 80.

[0096] Please refer to the following: Figure 2 , Figure 3 and Figure 20The unloading mechanism 10 includes a sixth driver 101, an unloading tray 102, an adhesive application module 103, and an unloading robot 104. The sixth driver 101, adhesive application module 103, and unloading robot 104 are all connected to the frame 1. The adhesive application module 103 is used to apply adhesive to the top surface of the capacitor 80 located in the clamping slot 416. The top of the unloading tray 102 is provided with multiple circumferentially arranged receiving slots 1021. The sixth driver 101 is a motor, connected to the unloading tray 102, and used to drive the unloading tray 102 to rotate. When the unloading tray 102 rotates, any one of the receiving slots 1021 on the unloading tray 102 can move directly below the clamping slot 416, so that when the clamp 41 opens, the capacitor 80 originally located in the clamping slot 416 can fall into any one of the receiving slots 1021. When the unloading tray 102 rotates to the adjacent position of the unloading robot 104, the unloading robot 104 will simultaneously take out two capacitors 80 from the two receiving slots 1021 and transfer the two picked-up capacitors 80 into the tray. Finally, the finished capacitors 80 are collected by the tray. The unloading robot 104 is a conventional two-axis or three-axis picking robot. The specific structure of the unloading robot 104 will not be described here.

[0097] In summary, this solution can automatically and accurately fit the heat shrink tubing 90 onto the capacitor 80, and can also automatically shorten the leads of the capacitor 80 to a preset length. The capacitor 80 does not need to have its leads cut in another device, thus greatly improving the production efficiency of the capacitor.
