Description

Technical Field

[0001] The present invention relates to the technical field of capacitor production, and in particular to an automatic discharge device for an electrolytic capacitor and a capacitor discharge method. Background Art

[0002] Electrolytic capacitors are energy storage components widely used in electronic devices. Their main function is to store electrical energy and be used for filtering, bypassing, coupling, etc. During the production process, electrolytic capacitors usually have a certain amount of residual charge inside. If these charges are not discharged and they are directly inserted into the PCB board, sensitive devices such as chips will be over-charged and fail. If the residual voltage of the electrolytic capacitor is too high, sparks may be generated at the moment of discharge, causing fire or electric shock accidents. Therefore, discharge treatment must be performed before inserting the electrolytic capacitor. At present, the traditional discharge method of electrolytic capacitors is to manually contact their pins with the discharge plate. This method has many disadvantages and hidden dangers: when discharging manually, it is difficult to guarantee the discharge time of the electrolytic capacitor on the discharge plate. Moreover, there is no limit device on the discharge plate. When the electrolytic capacitor contacts the discharge plate and tilts, the discharge will be invalid, and the residual electricity of the electrolytic capacitor cannot be completely released, which brings risks to the subsequent insertion into the PCB board, and may cause sensitive devices such as chips to fail due to over-electric damage. In addition, when the residual voltage of the incoming electrolytic capacitor is too high, sparks will be generated when the electrolytic capacitor contacts the discharge plate, which may not only damage the product, but more seriously, it will pose a threat to the personal safety of the operator. Furthermore, the manual operation force is unstable, and the force is difficult to control when manually discharging the electrolytic capacitor. Especially when the electrolytic capacitor contacts the discharge plate at an angle, the risk of excessive pressure causing the electrolytic capacitor pin to deform increases, and the pin deformation may affect the normal installation and performance of the electrolytic capacitor.

[0003] Therefore, it is necessary to improve the discharge process of the existing electrolytic capacitor to overcome the defects of the prior art. Summary of the invention

[0004] In order to overcome the problems existing in the related art, one of the purposes of the present invention is to provide an automatic discharge device for electrolytic capacitors, which can realize automatic discharge of electrolytic capacitors, improve the discharge efficiency of capacitors, reduce labor costs, and ensure the safety of capacitor discharge.

[0005] An automatic discharge device for an electrolytic capacitor, comprising:

[0006] A base, on which a discharge body is arranged, the discharge body comprising a discharge track and a baffle, the baffle being arranged on two opposite sides of the discharge track, a discharge plate being arranged at the bottom of the discharge track, and a discharge port being arranged at one end of the discharge track;

[0007] An angle adjustment structure is provided between the base and the discharge body, and the angle adjustment structure is used to adjust the angle between the surface of the discharge track and a horizontal plane.

[0008] During the use of the device, the inclination state of the discharge track is adjusted through the angle adjustment structure, so that the discharge track is set at a certain angle with the horizontal plane. Then the electrolytic capacitors to be discharged are placed at the starting end of the discharge track in sequence. Since the discharge track has a certain inclination angle, the capacitor begins to slide down along the track under the action of gravity. During the sliding process of the capacitor, its pin contacts the discharge plate to form a conductive path, realizing the automatic discharge of the capacitor. The baffle can form a certain limiting effect on the capacitor, which can not only prevent the capacitor from falling, but also prevent the capacitor from tilting excessively, ensuring that the capacitor pin can effectively contact the discharge plate, thereby ensuring a stable discharge effect. When the device is in use, the operator only needs to place the capacitor to be discharged at the starting end of the discharge track, and the subsequent discharge and discharging process are automatically completed by the device. Compared with the traditional manual discharge method, the manual operation links are greatly reduced and the dependence on manual labor is reduced. The baffles set on both sides of the discharge track can effectively prevent the capacitor from falling from both sides of the track during the sliding process, and avoid the capacitor from colliding with surrounding equipment or personnel. At the same time, the baffle can also prevent the sparks generated during the discharge process from splashing out, protecting the safety of the operator.

[0009] In a preferred technical solution of the present invention, the angle adjustment structure includes a mounting block and a connecting rod, the mounting block is arranged on the base, a mounting groove is arranged on the mounting block, and the length direction of the mounting groove is arranged along the length direction of the mounting block;

[0010] A first connecting shaft is arranged in the installation groove, the bottom of the connecting rod is rotatably matched with the first connecting shaft, and the top of the connecting rod is hinged to the bottom of the discharge track through a second connecting shaft.

[0011] In this embodiment, when the inclination angle of the discharge track needs to be adjusted, the operator can manually or electrically push the connecting rod to rotate around the first connecting axis. Since the top of the connecting rod is hinged to the bottom of the discharge track through the second connecting axis, the rotation of the connecting rod will drive the discharge track to rotate around the connection point with the base, thereby changing the inclination angle of the discharge track. During the adjustment process, the operator can accurately control the rotation angle of the connecting rod according to actual needs to achieve the desired inclination of the discharge track.

[0012] Preferably, after the discharge track is adjusted to a suitable inclination angle, a locking device (such as a bolt, a nut, etc.) can be provided on the first connecting shaft or the second connecting shaft to fix the relative position between the connecting rod and the mounting block and the discharge track, thereby ensuring that the inclination angle of the discharge track remains stable during the operation of the device.

[0013] In a preferred technical solution of the present invention, the first connecting shaft is movably arranged in the installation groove, and a locking member is arranged on the first connecting shaft, and the locking member is used to fix the first connecting shaft on the installation block.

[0014] In a preferred technical solution of the present invention, the locking member includes a mounting ring and a bayonet, the mounting ring is sleeved on the first connecting shaft, and the bayonet is fixed to a side wall of the mounting ring; a plurality of bayonet holes are provided on the mounting block, and the plurality of bayonet holes are provided on one side of the mounting groove along the length direction of the mounting groove, and the bayonet is adapted to the bayonet holes;

[0015] An elastic member is provided between the mounting ring and the first connecting shaft, the axis of the elastic member coincides with the axis of the first connecting shaft, one end of the elastic member is fixed on the first connecting shaft, and the other end oppositely is fixed on one side of the mounting ring.

[0016] In this embodiment, when the inclination angle of the discharge track needs to be adjusted, the position and angle of the connecting rod are initially changed by moving the position of the first connecting shaft in the mounting groove. Since the top of the connecting rod is hinged to the bottom of the discharge track, the movement of the first connecting shaft will drive the connecting rod to rotate, thereby changing the inclination angle of the discharge track. After the first connecting shaft is moved to a suitable position, it needs to be locked. The operator first pulls the mounting ring away from the mounting block, at which time the elastic member is stretched and the bayonet is pulled out of the original bayonet hole. Then the first connecting shaft is moved to the target position, and the mounting ring is released. Under the elastic force of the elastic member, the mounting ring moves toward the mounting block, and the bayonet is inserted into the corresponding bayonet hole, thereby fixing the first connecting shaft on the mounting block and completing the precise locking of the angle. If the inclination angle of the discharge track needs to be adjusted again later, the above-mentioned operation of pulling the mounting ring to pull out the bayonet, moving the first connecting shaft, and releasing the mounting ring to insert the bayonet can be repeated.

[0017] Compared with the traditional fixed angle adjustment method, the design of this embodiment can more accurately adjust the inclination of the discharge track according to the characteristics and discharge requirements of different capacitors, thereby optimizing the discharge effect of the capacitor and improving the discharge efficiency and quality.

[0018] The design of the elastic member between the mounting ring and the first connecting shaft makes the locking and unlocking operations simple and convenient. The operator only needs to pull and loosen the mounting ring and use the elastic force of the elastic member to easily insert and remove the bayonet pin without complicated tools or operating steps, which greatly improves the adjustment efficiency and reduces the labor intensity of the operator.

[0019] In a preferred technical solution of the present invention, support bars are respectively arranged on opposite sides of the discharge track, the length direction of the support bars is the same as the length direction of the baffle, and a side wall of each support bar is respectively connected to one side of the baffle.

[0020] The support bars are arranged on both sides of the discharge track to provide more stable support for the capacitor. Especially for some capacitors with larger size or higher center of gravity, the support bars can effectively prevent them from tipping over due to shaking during sliding, ensuring that the capacitor can pass through the discharge track smoothly, and improving the stability and reliability of the discharge process. The support bars cooperate with the baffle to form a stable guide channel. During the sliding process, the capacitor will be constrained by the support bars and baffles and can only move along the center line of the track, avoiding the left and right deviation of the capacitor on the track, ensuring the accurate contact between the capacitor pins and the discharge plate, and improving the discharge efficiency and quality.

[0021] In a preferred technical solution of the present invention, the baffle includes a first baffle and a second baffle, the first baffle is fixed on one side of the discharge track, and the second baffle is movably arranged on one side of the discharge track.

[0022] In a preferred technical solution of the present invention, a clamping groove is provided on the surface of the discharge track, and a clamping strip is provided on the bottom of the second baffle, and the clamping strip is matched with the clamping groove.

[0023] The movable design of the second baffle of the present application enables the device to easily adapt to electrolytic capacitors of different widths. Whether it is a small capacitor or a large capacitor, the discharge demand can be met by adjusting the position of the second baffle, which greatly improves the versatility of the device and reduces the cost of enterprises to purchase multiple devices for producing capacitors of different specifications.

[0024] Moreover, the second baffle is movable by the cooperation of the card strip and the card slot, and this structure makes the disassembly and installation of the second baffle very convenient. When performing maintenance and cleaning of the device, the operator can easily remove the second baffle from the track, and thoroughly clean the inside of the track to remove dust, debris, etc., to ensure the normal operation of the device.

[0025] In a preferred technical solution of the present invention, a buffer plate is provided at the discharge port, one side of the buffer plate is hinged to the discharge track, and a buffer pad is provided on the surface of the buffer plate.

[0026] The buffer plate and buffer pad structure of the present application can effectively absorb the kinetic energy of the capacitor, greatly reduce the impact force on the capacitor, reduce the damage rate of the capacitor, and improve the yield rate of the product.

[0027] The buffer plate and buffer pad share the impact force when the capacitor is discharged, reducing the wear of the discharge port and related parts. Compared with the device without a buffer structure, the wear degree of the discharge port parts of the device of the present application is significantly reduced during long-term use, extending the overall service life of the device.

[0028] In a preferred technical solution of the present invention, a plurality of discharge contacts are provided on the discharge plate, and the plurality of discharge contacts are arranged on the discharge plate along the length direction of the discharge track.

[0029] In this embodiment, by adding discharge contacts on the basis of the discharge plate, during the sliding process of the capacitor, its pins will contact multiple discharge contacts on the discharge plate in turn. When the capacitor pins contact the discharge contacts, a conductive path is formed between the discharge contacts to achieve the discharge of the capacitor. As the capacitor continues to slide, its pins will contact different discharge contacts in turn, and discharge multiple times to ensure that the residual electricity in the capacitor can be fully released. The setting of the discharge contacts can effectively improve the discharge effect of the device on the capacitor.

[0030] A second object of the present invention is to provide a capacitor discharge method, which is implemented based on the electrolytic capacitor automatic discharge device as described above.

[0031] The beneficial effects of the present invention are:

[0032] The present invention provides an automatic discharge device for an electrolytic capacitor, which includes a base, a discharge body is arranged on the base, the discharge body includes a discharge track and a baffle, the baffle is arranged on two opposite sides of the discharge track, a discharge plate is arranged at the bottom of the discharge track, and a discharge port is arranged at one end of the discharge track. An angle adjustment structure is arranged between the base and the discharge body, and the angle adjustment structure is used to adjust the angle between the surface of the discharge track and the horizontal plane. During use, the device uses the angle adjustment structure to adjust the placement angle of the discharge track so that the discharge track is in an inclined state. During the discharge operation, the electrolytic capacitor to be discharged is placed at the starting end of the discharge track in sequence. Since the discharge track has a certain inclination angle, the capacitor begins to slide down along the track under the action of gravity. During the sliding process of the capacitor, its pin contacts the discharge plate to form a conductive path, thereby realizing the automatic discharge of the capacitor. The whole process does not require manual intervention, which greatly improves the discharge speed. In large-scale production scenarios, the discharge time of the capacitor can be significantly shortened and the output per unit time can be increased. The insulating plastic baffles arranged on both sides of the discharge track can effectively prevent the capacitor from falling from both sides of the track during the sliding process, and avoid collision between the capacitor and surrounding equipment or personnel. At the same time, the baffle can prevent the sparks generated during the discharge process from flying out, protecting the safety of the operator.

[0033] The present application also provides a capacitor discharge method implemented based on the above-mentioned electrolytic capacitor automatic discharge device, which can realize automatic discharge of electrolytic capacitors, reduce the labor cost and labor intensity of capacitor production, and improve production efficiency.

[0043] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0044] The traditional discharge method of existing electrolytic capacitors is to manually contact their pins with the discharge plate. This method has many disadvantages and hidden dangers: when discharging manually, it is difficult to ensure the discharge time of the electrolytic capacitor on the discharge plate. In addition, there is no limit device on the discharge plate. When the electrolytic capacitor contacts the discharge plate and tilts, the discharge will be invalid, making it impossible to completely release the residual electricity of the electrolytic capacitor, which will bring risks to the subsequent insertion into the PCB board, and may cause sensitive devices such as chips to fail due to over-electric damage; in addition, when the residual voltage of the incoming electrolytic capacitor is too high, sparks will be generated when the electrolytic capacitor contacts the discharge plate, which may not only damage the product, but more seriously, it will pose a threat to the personal safety of the operator; furthermore, the manual operation force is unstable, and the force is difficult to control when manually discharging the electrolytic capacitor. Especially when the electrolytic capacitor contacts the discharge plate at an angle, the risk of excessive pressure causing the electrolytic capacitor pin to deform is increased, and the pin deformation may affect the normal installation and use performance of the electrolytic capacitor.

[0045] Based on this, the present application provides an automatic discharge device for an electrolytic capacitor.

[0046] Example 1

[0047] like Figure 1-Figure 7 As shown, this embodiment provides an electrolytic capacitor automatic discharge device, comprising:

[0048] A base 1, on which a discharge body 2 is arranged, the discharge body 2 comprises a discharge track 23 and a baffle, the baffle being arranged on two opposite sides of the discharge track 23, a discharge plate 24 being arranged at the bottom of the discharge track 23, and a discharge port being arranged at one end of the discharge track 23;

[0049] An angle adjustment structure 3 is provided between the base 1 and the discharge body 2 , and the angle adjustment structure 3 is used to adjust the angle between the surface of the discharge track 23 and a horizontal plane.

[0050] Specifically, the base 1 is made of high-strength metal material (such as stainless steel) and has good stability and load-bearing capacity. An anti-slip rubber pad is provided at the bottom to effectively prevent the device from sliding during operation. On the upper surface of the base 1, a mounting groove 311 and a fixing hole adapted to the angle adjustment structure 3 are provided for accurately installing and fixing the angle adjustment structure 3.

[0051] The discharge track 23 is made of aluminum alloy, and the surface is anodized, which has good wear resistance and conductivity. The width of the track is designed according to the size of common electrolytic capacitors to ensure that the capacitor can slide smoothly in the track. The bottom of the track is flat for installing the discharge plate 24.

[0052] The baffle is vertically arranged on opposite sides of the discharge track 23, and its height is slightly higher than the height of the electrolytic capacitor. The baffle is made of insulating plastic material, which can effectively prevent the capacitor from falling from both sides of the track during sliding, and at the same time prevent the operator from contacting the discharge area, thereby improving safety. The baffle is fixedly connected to the discharge track 23 by bolts, which is convenient for disassembly and replacement. The discharge plate 24 is made of highly conductive copper material, and the surface is silver-plated to reduce contact resistance. The discharge plate 24 is fixed to the bottom of the discharge track 23 by welding, and fits tightly with the track to ensure that the capacitor pins can fully contact with the discharge plate 24.

[0053] During use, the device adjusts the inclination of the discharge track 23 through the angle adjustment structure 3, so that the discharge track 23 is set at a certain angle with the horizontal plane. Then the electrolytic capacitors to be discharged are placed at the starting end of the discharge track 23 in sequence. Since the discharge track 23 has a certain inclination angle, the capacitor begins to slide down along the track under the action of gravity. During the sliding process of the capacitor, its pin contacts the discharge plate 24 to form a conductive path, thereby realizing the automatic discharge of the capacitor. The baffle can form a certain limiting effect on the capacitor, which can prevent the capacitor from falling and prevent the capacitor from tilting too much, ensuring that the capacitor pin can effectively contact the discharge plate 24, thereby ensuring a stable discharge effect. When the device is in use, the operator only needs to place the capacitor to be discharged at the starting end of the discharge track 23, and the subsequent discharge and discharging processes are automatically completed by the device. Compared with the traditional manual discharge method, the manual operation links are greatly reduced and the dependence on manual labor is reduced. The baffles set on both sides of the discharge track 23 can effectively prevent the capacitor from falling from both sides of the track during the sliding process, and avoid collisions between the capacitor and surrounding equipment or personnel. At the same time, the baffle can prevent the sparks generated during the discharge process from flying out, protecting the safety of the operator.

[0054] In this embodiment, the angle adjustment structure 3 may be a cylinder fixed on the base 1 , and the angle between the discharge track 23 and the horizontal plane is changed by the extension and retraction of the piston rod of the cylinder.

[0055] Example 2

[0056] like Figure 1-Figure 7 As shown, this embodiment is improved on the basis of embodiment 1.

[0057] In this embodiment, an implementation of an angle adjustment structure 3 different from that of embodiment 1 is provided. The angle adjustment structure 3 includes a mounting block 31 and a connecting rod 32. The mounting block 31 is disposed on the base 1. A mounting groove 311 is disposed on the mounting block 31. The length direction of the mounting groove 311 is disposed along the length direction of the mounting block 31.

[0058] A first connecting shaft 33 is disposed in the installation groove 311 , and the bottom of the connecting rod 32 is rotatably matched with the first connecting shaft 33 , and the top of the connecting rod 32 is hinged to the bottom of the discharge track 23 through a second connecting shaft 34 .

[0059] The size of the mounting groove 311 is precisely designed, with a width slightly larger than the width of the connecting rod 32 and a depth capable of accommodating the first connecting shaft 33 .

[0060] The first connecting shaft 33 passes through the installation groove 311 . The first connecting shaft 33 is made of stainless steel, and its surface is polished to ensure that the connecting rod 32 can rotate smoothly around the first connecting shaft 33 .

[0061] In this embodiment, when the inclination angle of the discharge track 23 needs to be adjusted, the operator can manually push the connecting rod 32 to rotate around the first connecting shaft 33. Since the top of the connecting rod 32 is hinged to the bottom of the discharge track 23 through the second connecting shaft 34, the rotation of the connecting rod 32 will drive the discharge track 23 to rotate around the connection point with the base 1, thereby changing the inclination angle of the discharge track 23. During the adjustment process, the operator can accurately control the rotation angle of the connecting rod 32 according to actual needs to achieve the desired inclination of the discharge track 23.

[0062] More preferably, after the discharge track 23 is adjusted to a suitable inclination angle, a locking device (such as a bolt, a nut, etc.) can be provided on the first connecting shaft 33 or the second connecting shaft 34 to fix the relative position between the connecting rod 32, the mounting block 31 and the discharge track 23, thereby ensuring that the inclination angle of the discharge track 23 remains stable during the operation of the device.

[0063] In different production environments and production processes, the requirements for capacitor discharge may be different. The existence of the angle adjustment structure 3 enables the device to flexibly adjust the inclination angle of the discharge track 23 according to actual production needs, thereby meeting diverse production requirements and improving the market competitiveness of the device.

[0064] Example 3

[0065] like Figure 1-Figure 7 As shown, this embodiment is improved on the basis of embodiment 2.

[0066] In this embodiment, the first connecting shaft 33 is movably disposed in the mounting groove 311 , and a locking member 35 is disposed on the first connecting shaft 33 , and the locking member 35 is used to fix the first connecting shaft 33 on the mounting block 31 .

[0067] Specifically, in this embodiment, the locking member 35 includes a mounting ring 351 and a bayonet 352, the mounting ring 351 is sleeved on the first connecting shaft 33, and the bayonet 352 is fixed to a side wall of the mounting ring 351; the mounting block 31 is provided with a plurality of bayonet holes 312, and the plurality of bayonet holes 312 are arranged on one side of the mounting groove 311 along the length direction of the mounting groove 311, and the bayonet pin 352 is adapted to the bayonet holes 312;

[0068] An elastic member 36 is provided between the mounting ring 351 and the first connecting shaft 33 , the axis of the elastic member 36 coincides with the axis of the first connecting shaft 33 , one end of the elastic member 36 is fixed on the first connecting shaft 33 , and the other end is fixed on one side of the mounting ring 351 .

[0069] In this embodiment, when the inclination angle of the discharge track 23 needs to be adjusted, the position and angle of the connecting rod 32 are initially changed by moving the position of the first connecting shaft 33 in the mounting groove 311. Since the top of the connecting rod 32 is hinged to the bottom of the discharge track 23, the movement of the first connecting shaft 33 will drive the connecting rod 32 to rotate, thereby changing the inclination angle of the discharge track 23. After the first connecting shaft 33 is moved to a suitable position, it needs to be locked. The operator first pulls the mounting ring 351 in a direction away from the mounting block 31, at which time the elastic member 36 is stretched and the bayonet 352 is pulled out of the original bayonet hole 312. Then the first connecting shaft 33 is moved to the target position, and the mounting ring 351 is released. Under the elastic force of the elastic member 36, the mounting ring 351 moves toward the mounting block 31, and the bayonet 352 is inserted into the corresponding bayonet hole 312, thereby fixing the first connecting shaft 33 on the mounting block 31, and completing the precise locking of the angle. If the inclination angle of the discharge track 23 needs to be adjusted again later, the above operations of pulling the installation ring 351 to remove the bayonet 352 , moving the first connecting shaft 33 , loosening the installation ring 351 and inserting the bayonet 352 can be repeated.

[0070] Compared with the traditional fixed angle adjustment method, the design of this embodiment can more accurately adjust the inclination of the discharge track 23 according to the characteristics and discharge requirements of different capacitors, thereby optimizing the discharge effect of the capacitor and improving the discharge efficiency and quality.

[0071] The design of the elastic member 36 between the mounting ring 351 and the first connecting shaft 33 makes the locking and unlocking operations simple and convenient. The operator only needs to pull and loosen the mounting ring 351 and use the elastic force of the elastic member 36 to easily insert and remove the bayonet 352 without complicated tools or operating steps, which greatly improves the adjustment efficiency and reduces the labor intensity of the operator.

[0072] Specifically, the elastic member 36 of the present application may be a spring.

[0073] Example 4

[0074] like Figure 1-Figure 7 As shown, this embodiment is improved on the basis of embodiment 1.

[0075] In this embodiment, support bars 22 are respectively provided on opposite sides of the discharge track 23 , the length direction of the support bars 22 is the same as the length direction of the baffle, and a side wall of each support bar 22 is respectively connected to one side of the baffle.

[0076] In actual applications, the support bar 22 is made of high-strength aluminum alloy and is manufactured through an extrusion molding process, and has good strength and rigidity. Its cross-sectional shape is a rectangle, which is easy to process and manufacture, and can provide stable support. The length direction of the support bar 22 is the same as the length direction of the baffle, and a side wall of each support bar 22 is connected to one side of the baffle respectively. The support bar 22 is firmly connected to the baffle by welding to ensure the connection strength and stability between the two. The distance between the two support bars 22 should be greater than the diameter between the pins of the capacitor to avoid damage to the pins due to collision between the pins and the support bar 22 during the discharge process of the capacitor.

[0077] The support bars 22 are arranged on both sides of the discharge track 23 to provide a more stable support for the capacitor. Especially for some capacitors with larger sizes or higher center of gravity, the support bars 22 can effectively prevent them from tipping over due to shaking during the sliding process, ensuring that the capacitor can smoothly pass through the discharge track 23, and improving the stability and reliability of the discharge process. The support bars 22 cooperate with the baffle to form a stable guide channel. During the sliding process, the capacitor will be constrained by the support bars 22 and the baffle, and can only move along the center line of the track, avoiding the left and right deviation of the capacitor on the track, ensuring the accurate contact between the capacitor pins and the discharge plate 24, and improving the discharge efficiency and quality.

[0078] Preferably, the upper surface of the support bar 22 is finely polished and smooth, which can effectively reduce the friction between the capacitor and the support bar 22. During the sliding of the capacitor, the contact between the pin and the discharge plate 24 is more stable, which reduces the deformation or damage of the pin caused by friction and improves the yield rate of the capacitor.

[0079] Example 5

[0080] like Figure 1-Figure 7 As shown, this embodiment is improved on the basis of embodiment 4.

[0081] In this embodiment, the baffle includes a first baffle 21 and a second baffle 25 . The first baffle 21 is fixed to one side of the discharge track 23 , and the second baffle 25 is movably disposed on one side of the discharge track 23 .

[0082] Furthermore, a plurality of slots 231 are provided on the surface of the discharge track 23, and a clip strip 251 is provided at the bottom of the second baffle 25, and the clip strip 251 is adapted to the slots 231. The plurality of slots 231 are arranged along the width direction between the first baffle 21 and the second baffle 25, and the length direction of each slot 231 is the same as the length direction of the second baffle 25. By adjusting the clip strip 251 to match different slots 231, the distance between the second baffle 25 and the first baffle 21 can be changed.

[0083] The movable design of the second baffle 25 of the present application enables the device to easily adapt to electrolytic capacitors of different widths. Whether it is a small capacitor or a large capacitor, the discharge demand can be met by adjusting the position of the second baffle 25, which greatly improves the versatility of the device and reduces the cost of enterprises to purchase multiple devices for producing capacitors of different specifications.

[0084] Moreover, the second baffle 25 is movable by the cooperation between the clamping strip 251 and the clamping slot 231, and this structure makes it very convenient to disassemble and install the second baffle 25. When performing maintenance and cleaning of the device, the operator can easily remove the second baffle 25 from the track, and thoroughly clean the inside of the track to remove dust, debris, etc., to ensure the normal operation of the device.

[0085] Specifically, the slot 231 may be a dovetail slot.

[0086] Example 6

[0087] like Figure 1-Figure 7 As shown, this embodiment is improved on the basis of embodiment 1.

[0088] In this embodiment, a buffer plate 26 is provided at the discharge port, one side of the buffer plate 26 is hinged to the discharge track 23 , and a buffer pad 261 is provided on the surface of the buffer plate 26 .

[0089] The buffer plate 26 is made of a light and strong aluminum alloy material, and is rectangular in shape and has a size that matches the discharge port. One side of the buffer plate 26 is hinged to the edge of the discharge port of the discharge track 23 through a hinge, and this hinge allows the buffer plate 26 to rotate around the hinge axis within a certain range, providing a buffering space for the capacitor.

[0090] The buffer pad 261 is laid on the surface of the buffer plate 26 and is made of a soft and elastic rubber material or sponge. The buffer pad 261 is firmly attached to the buffer plate 26 by strong glue, and its surface has fine convex textures to increase the friction with the capacitor surface and prevent the capacitor from sliding during the buffering process.

[0091] The buffer plate 26 and buffer pad 261 structure of the present application can effectively absorb the kinetic energy of the capacitor, greatly reduce the impact force on the capacitor, reduce the damage rate of the capacitor, and improve the yield rate of the product.

[0092] The buffer plate 26 and the buffer pad 261 share the impact force when the capacitor is discharged, reducing the wear of the discharge port and related components. Compared with the device without a buffer structure, the wear degree of the discharge port components of the device of the present application is significantly reduced during long-term use, extending the overall service life of the device.

[0093] Example 7

[0094] like Figure 1-Figure 7 As shown, this embodiment is improved on the basis of embodiment 1.

[0095] In this embodiment, a plurality of discharge contacts are disposed on the discharge plate 24 , and the plurality of discharge contacts are arranged on the discharge plate 24 along the length direction of the discharge track 23 .

[0096] Specifically, the discharge contact of the present application adopts a spring pin structure, which is mainly composed of a needle tube, a spring and a needle. The needle tube is made of a highly conductive copper alloy material, and its inner wall is silver-plated to reduce resistance and improve conductivity. The spring is placed inside the needle tube, has good elasticity and resilience, and can ensure that the needle quickly returns to its original position after being subjected to pressure. The needle is made of stainless steel, and its head is polished and has a smooth surface to ensure good contact with the electrolytic capacitor pin. Multiple discharge contacts are evenly arranged on the discharge plate 24 along the length direction of the discharge track 23. The spacing between adjacent discharge contacts is designed according to the pin spacing of common electrolytic capacitors to ensure that the pins of the capacitor can contact each discharge contact in turn during the sliding process on the track. The discharge contacts are fixed to the discharge plate 24 by welding to ensure the stability and conductivity of the connection.

[0097] In this embodiment, by adding discharge contacts on the basis of the discharge plate 24, during the sliding process of the capacitor, its pins will sequentially contact multiple discharge contacts on the discharge plate 24. When the capacitor pins contact the discharge contacts, a conductive path is formed between the discharge contacts to achieve the discharge of the capacitor. As the capacitor continues to slide, its pins will sequentially contact different discharge contacts, and discharge multiple times to ensure that the residual electricity in the capacitor can be fully released. The setting of the discharge contacts can effectively improve the discharge effect of the device on the capacitor.

[0098] Example 8

[0099] like Figure 1-Figure 7 As shown, this embodiment provides a capacitor discharge method, which is implemented based on the electrolytic capacitor automatic discharge device as described above.

[0100] Specifically, the capacitor discharge method has the following steps:

[0101] Place the electrolytic capacitor automatic discharge device on a stable workbench, check the angle adjustment structure 3, and adjust the discharge track 23 to a suitable tilt angle by moving the first connecting shaft 33 in the mounting groove 311 and fixing it with the locking member 35. According to the specifications of the capacitor to be discharged, move the second baffle 25 along the slot 231, and adjust the spacing between the first baffle 21 and the second baffle 25 to just fit the width of the capacitor.

[0102] The electrolytic capacitors to be discharged are sequentially placed at the starting end of the discharge track 23. Pay attention to the placement direction of the capacitors, and ensure that their pins face downward so that they can effectively contact the discharge contacts on the discharge plate 24 during the sliding process.

[0103] Since the discharge track 23 has a certain inclination angle, the capacitor starts to slide down along the track under the action of its own gravity. During the sliding process, the support bars 22 on both sides of the discharge track 23 provide additional support for the capacitor to prevent it from tipping over; the first baffle 21 and the second baffle 25 limit and guide the capacitor to ensure that the capacitor moves smoothly along the center line of the track.

[0104] During the sliding process of the capacitor, its pins will contact the discharge contacts on the discharge plate 24 to form a conductive path to discharge the capacitor. As the capacitor continues to slide, its pins will continue to discharge to ensure that the residual electricity in the capacitor can be fully released.

[0105] When the capacitor is discharged, it slides to the discharge port and first contacts the buffer pad 261 on the surface of the buffer plate 26 at the discharge port. The buffer pad 261 undergoes elastic deformation to absorb part of the kinetic energy of the capacitor, and at the same time, the buffer plate 26 rotates upward around the hinge axis by a certain angle to further reduce the impact force of the capacitor, so that the capacitor can stay on the buffer plate 26 stably.

[0106] After the capacitor is stabilized on the buffer plate 26 , the capacitor is removed from the buffer plate 26 by a manual or automated conveying device to proceed to subsequent production processes.

[0107] The method can realize automatic discharge of the capacitor and improve the production efficiency of the capacitor.
