Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of capacitor production, especially relates to a electrolytic capacitor automatic discharging device. BACKGROUND

[0002] The electrolytic capacitor is a kind of energy storage element widely used in electronic equipment, and its main function is to store electric energy and be used for filtering, bypass, coupling etc.The electrolytic capacitor is usually left with certain electric charge in the production process.If the electric charge is not discharged and directly inserted into PCB board, it will cause the chip and other sensitive devices to be damaged by overvoltage, and if the residual voltage of electrolytic capacitor is too high, spark may be generated in the discharging moment, which may cause fire or electric shock accident.Therefore, the electrolytic capacitor must be discharged before insertion.Currently, the traditional discharging method of electrolytic capacitor is to contact the pin with discharging plate manually.This method has many shortcomings and hidden dangers:when discharging manually, it is difficult to ensure the discharging time of electrolytic capacitor on the discharging plate.Moreover, there is no limiting device on the discharging plate, and when electrolytic capacitor contacts the discharging plate obliquely, it will cause ineffective discharging, so that the residual electricity of electrolytic capacitor cannot be completely released, which brings risks to subsequent insertion into PCB board, and may cause the chip and other sensitive devices to be damaged by overvoltage;in addition, when the residual voltage of incoming electrolytic capacitor is too high, spark may be generated when electrolytic capacitor contacts the discharging plate, which not only may damage the product, but also seriously threatens the personal safety of operator;furthermore, the manual operation force is unstable, and it is difficult to control the force when discharging electrolytic capacitor manually.Especially when electrolytic capacitor contacts the discharging plate obliquely, it increases the risk of deforming the pin of electrolytic capacitor caused by excessive pressing, and the deformation of pin may affect the normal installation and use performance of electrolytic capacitor.

[0003] Therefore, it is necessary to improve the discharging process of existing electrolytic capacitor to overcome the defects of prior art. UTILITY MODEL CONTENTS

[0004] To overcome the problems in the prior art, the purpose of the utility model is to provide an electrolytic capacitor automatic discharging device, which can realize automatic discharging of electrolytic capacitor, improve the discharging efficiency of capacitor, reduce labor cost and ensure the safety of capacitor discharging.

[0005] An electrolytic capacitor automatic discharging device, comprising:

[0006] A base is provided with a discharging body, the discharging body comprises a discharging track and a baffle, the baffle is arranged on the opposite sides of the discharging track, the bottom of the discharging track is provided with a discharging plate, and one end of the discharging track is provided with a discharge port;

[0007] An angle adjusting structure is arranged between the base and the discharge main body, and is used to adjust the included angle between the surface of the discharge track and the horizontal plane.

[0008] In use, the device adjusts the inclination of the discharge track through the angle adjusting structure, so that the discharge track is arranged at a certain included angle with the horizontal plane. Then the electrolytic capacitor to be discharged is placed in turn at the starting end of the discharge track. Since the discharge track has a certain inclination angle, the capacitor starts to slide 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 automatic discharge of the capacitor. The baffle can form a certain limiting effect on the capacitor, which can prevent the capacitor from falling and also prevent the capacitor from tilting too much, so as to ensure that the pin of the capacitor can effectively contact the discharge plate, thereby ensuring stable discharge effect. 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 processes are automatically completed by the device. Compared with the traditional manual discharge method, the manual operation link is greatly reduced, and the dependence on manual operation is reduced. The baffle 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, thereby avoiding collision between the capacitor and surrounding equipment or personnel. At the same time, the baffle can also prevent sparks generated during the discharge process from splashing out, thereby protecting the safety of the operator.

[0009] In the preferred technical scheme of the utility model, the angle adjusting structure comprises 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 mounting groove, the bottom of the connecting rod is rotationally connected with the first connecting shaft, and the top of the connecting rod is hingedly connected with the bottom of the discharge track through a second connecting shaft.

[0011] In this embodiment, when it is necessary to adjust the inclination angle of the discharge track, the operator can manually or electrically push the connecting rod to rotate around the first connecting shaft. Since the top of the connecting rod is hingedly connected with the bottom of the discharge track through the second connecting shaft, the rotation of the connecting rod will drive the discharge track to rotate around the connecting 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, so as to achieve the required inclination of the discharge track.

[0012] More preferably, when the discharge track is adjusted to a suitable inclination angle, a locking device (such as a bolt, a nut, etc.) can be arranged on the first connecting shaft or the second connecting shaft to fix the relative positions between the connecting rod and the mounting block and the discharge track, so as to ensure that the inclination angle of the discharge track remains stable during the operation of the device.

[0013] In the preferable technical scheme of the utility model, the first connecting shaft is movably arranged in the mounting groove, and a locking piece is arranged on the first connecting shaft, which is used for fixing the first connecting shaft on the mounting block.

[0014] In the preferable technical scheme of the utility model, the locking piece comprises a mounting ring and a pin, the mounting ring is sleeved on the first connecting shaft, and the pin is fixed on one side wall of the mounting ring; a plurality of clamping holes are arranged on the mounting block, the plurality of clamping holes are arranged on one side of the mounting groove along the length direction of the mounting groove, and the pin is matched with the clamping hole.

[0015] An elastic piece is arranged between the mounting ring and the first connecting shaft, the axis of the elastic piece is coincident with the axis of the first connecting shaft, one end of the elastic piece is fixed on the first connecting shaft, and the opposite end is fixed on one side of the mounting ring.

[0016] In the embodiment, when the inclination angle of the discharge track needs to be adjusted, the position and angle of the connecting rod are preliminarily changed by moving the first connecting shaft in the mounting groove first. Since the top of the connecting rod is hinged to the bottom of the discharge track, the movement of the first connecting shaft drives the connecting rod to rotate, and then the inclination angle of the discharge track is changed. After the first connecting shaft is moved to the appropriate position, it needs to be locked. The operator first pulls the mounting ring away from the mounting block, at this time, the elastic piece is stretched, and the pin is pulled out of the original clamping hole. Then the first connecting shaft is moved to the target position, and the mounting ring is released. Under the action of the elastic force of the elastic piece, the mounting ring moves towards the mounting block, the pin is inserted into the corresponding clamping hole, so that the first connecting shaft is fixed on the mounting block, and the accurate locking of the angle is completed. If the inclination angle of the discharge track needs to be adjusted again subsequently, the above-mentioned operations of pulling the mounting ring to pull out the pin, moving the first connecting shaft, releasing the mounting ring to insert the pin can be repeated.

[0017] Compared with the conventional fixed-angle adjustment mode, the design can more accurately adjust the inclination of the discharge track according to the characteristics of different capacitors and discharge requirements, so as to optimize the discharge effect of the capacitor and improve the discharge efficiency and quality.

[0018] The elastic piece 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 release the mounting ring, and the elastic force of the elastic piece can easily realize the insertion and extraction of the pin, without the need for complex tools or operation steps, so that the adjustment efficiency is greatly improved, and the labor intensity of the operator is reduced.

[0019] In the preferable technical scheme of the utility model, the opposite two sides of the discharge track are respectively provided with support strips, the length direction of the support strip is same with the length direction of the baffle, and the side wall of each support strip is respectively connected with one side of the baffle.

[0020] The support strips are arranged on the two sides of the discharge track, which provides more stable support for the capacitor. Especially for some large size or high gravity center capacitors, the support strips can effectively prevent them from rolling over due to shaking during sliding, ensuring that the capacitor can smoothly pass through the discharge track, improving the stability and reliability of the discharge process. The support strips cooperate with the baffles to form a stable guide channel. During the sliding process of the capacitor, it will be constrained by the support strips and baffles, and can only move forward along the center line of the track, avoiding the left and right deviation of the capacitor on the track, ensuring the accurate contact of the capacitor pin with the discharge plate, and improving the discharge efficiency and quality.

[0021] In the preferable technical scheme of the utility model, the baffle comprises 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 the preferable technical scheme of the utility model, the surface of the discharge track is provided with a clamping groove, the bottom of the second baffle is provided with a clamping strip, and the clamping strip is matched with the clamping groove.

[0023] The movable design of the second baffle of the application makes the device easily adapt to electrolytic capacitors of different widths. Whether it is a small capacitor or a large capacitor, the discharge requirements of the capacitor can be met by adjusting the position of the second baffle, greatly improving the versatility of the device and reducing the cost of purchasing multiple equipment for producing capacitors of different specifications.

[0024] Moreover, the second baffle is movably arranged through the cooperation of the clamping strip and the clamping groove, and such a structure makes the disassembly and installation of the second baffle very convenient. When maintaining and cleaning the device, the operator can easily remove the second baffle from the track, and comprehensively clean the inside of the track to remove dust, debris and the like, ensuring the normal operation of the device.

[0025] In the preferable technical scheme of the utility model, a buffer plate is arranged at the discharge outlet, one side of the buffer plate is hingedly connected with the discharge track, and a buffer pad is arranged on the surface of the buffer plate.

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

[0027] The buffer plate and the buffer pad share the impact force when the capacitor discharges, and reduce the abrasion of the discharge port and related components.

[0028] In the preferable technical scheme of the utility model, a plurality of discharge contacts are arranged on the discharge plate along the length direction of the discharge track.

[0029] In the embodiment, the discharge contacts are added to the discharge plate, and the pins of the capacitor will contact the plurality of discharge contacts on the discharge plate in turn during the sliding of the capacitor. When the pins of the capacitor contact the discharge contacts, a conductive path is formed between the pins and the discharge contacts, and the discharge of the capacitor is realized. With the continuous sliding of the capacitor, the pins will contact different discharge contacts in turn, and the discharge is performed for multiple times, so that the residual electricity in the capacitor can be fully discharged. The arrangement of the discharge contacts can effectively improve the discharge effect of the device on the capacitor.

[0041] The preferred embodiments of the utility model will be described in more detail below with reference to the drawings. Although the preferred embodiments of the utility model are shown in the drawings, it should be understood that the utility model can be realized in various forms and should not be limited by the embodiments described here. On the contrary, these embodiments are provided to make the utility model more thorough and complete, and to fully convey the scope of the utility model to those skilled in the art.

[0042] The conventional discharging mode of the existing electrolytic capacitor is to manually contact the pin with the discharging plate. This mode has many shortcomings and hidden dangers: when discharging manually, it is difficult to ensure the discharging time of the electrolytic capacitor on the discharging plate. Moreover, there is no limiting device on the discharging plate, and when the electrolytic capacitor contacts the discharging plate obliquely, it will cause ineffective discharging, so that the residual electricity of the electrolytic capacitor cannot be completely discharged, which brings risks to subsequent insertion into the PCB, and may cause the sensitive devices such as chips to be damaged by overvoltage and fail. In addition, when the incoming electrolytic capacitor has a too high residual voltage, a spark will be generated when the electrolytic capacitor contacts the discharging plate instantaneously, which not only may damage the product, but more seriously, may pose a threat to the personal safety of the operator. Furthermore, the manual operation force is unstable, and when discharging the electrolytic capacitor manually, the force cannot be well controlled. Especially when the electrolytic capacitor contacts the discharging plate obliquely, it increases the risk of over-pressing the electrolytic capacitor pin, which may affect the normal installation and use performance of the electrolytic capacitor.

[0043] Based on this, the present application provides an electrolytic capacitor automatic discharging device.

[0044] Embodiment 1

[0045] As shown in Figures 1-7 The present embodiment provides an electrolytic capacitor automatic discharging device, which comprises:

[0046] A base 1 is provided with a discharging body 2, the discharging body 2 comprises a discharging track 23 and a baffle, the baffle is arranged on the opposite sides of the discharging track 23, the bottom of the discharging track 23 is provided with a discharging plate 24, and one end of the discharging track 23 is provided with a discharge port;

[0047] An angle adjusting structure 3 is arranged between the base 1 and the discharging body 2, and is used for adjusting the included angle between the surface of the discharging track 23 and the horizontal plane.

[0048] Specifically, the base 1 is made of high-strength metal material (such as stainless steel), has good stability and bearing capacity. The bottom is provided with an anti-skid rubber pad, which can effectively prevent the device from sliding during work. On the upper surface of the base 1, a mounting groove 311 and a fixing hole are arranged, which are matched with the angle adjusting structure 3, and are used for accurately installing and fixing the angle adjusting structure 3.

[0049] The discharging track 23 is made of aluminum alloy material, and the surface is subjected to anodic oxidation treatment, so as to have good wear resistance and conductivity. The width of the track is designed according to the size of the common electrolytic capacitor, so as to ensure that the capacitor can smoothly slide in the track. The bottom of the track is flat, and is used for installing the discharging plate 24.

[0050] The baffle is vertically arranged on the opposite sides of the discharge track 23 and has a height slightly higher than that of the electrolytic capacitor. The baffle is made of insulating plastic material and can effectively prevent the capacitor from falling off from the two sides of the track during sliding and avoid the operator from contacting the discharge area, thereby improving safety. The baffle is fixedly connected to the discharge track 23 through bolts, facilitating disassembly and replacement. The discharge plate 24 is made of copper material with high electrical conductivity and is plated with silver on the surface to reduce the contact resistance. The discharge plate 24 is fixed to the bottom of the discharge track 23 through welding and closely adheres to the track, ensuring that the capacitor pin can fully contact the discharge plate 24.

[0051] During use, the device adjusts the inclination of the discharge track 23 through the angle adjusting structure 3 to set the discharge track 23 at a certain angle with the horizontal plane. Then, the electrolytic capacitor to be discharged is placed at the starting end of the discharge track 23. Due to the inclination of the discharge track 23, the capacitor starts to slide along the track under the action of gravity. During the sliding of the capacitor, its pin contacts the discharge plate 24 to form a conductive path, realizing automatic discharge of the capacitor. The baffle can limit the capacitor to a certain extent, preventing the capacitor from falling off and preventing the capacitor from tilting too much, ensuring that the capacitor pin can effectively contact the discharge plate 24, thereby ensuring stable discharge effect. When using the device, 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 discharge processes are automatically completed by the device. Compared with the traditional manual discharge method, the device greatly reduces the manual operation link and reduces the dependence on manpower. The baffle arranged on both sides of the discharge track 23 can effectively prevent the capacitor from falling off from the two sides of the track during sliding and prevent the capacitor from colliding with surrounding equipment or personnel. At the same time, the baffle can also prevent sparks generated during discharge from splashing out, protecting the safety of the operator.

[0052] In this embodiment, the angle adjusting structure 3 can be a gas 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 gas cylinder.

[0053] Embodiment 2

[0054] As shown in Figures 1-7 , this embodiment is improved on the basis of embodiment 1.

[0055] In this embodiment, an implementation of the angle adjusting structure 3 different from that of embodiment 1 is provided. The angle adjusting structure 3 includes a mounting block 31 and a connecting rod 32, the mounting block 31 is arranged on the base 1, and the mounting block 31 is provided with a mounting groove 311, the length direction of the mounting groove 311 is arranged along the length direction of the mounting block 31;

[0056] The first connecting shaft 33 is arranged in the mounting groove 311, the bottom of the connecting rod 32 is rotationally connected with the first connecting shaft 33, and the top of the connecting rod 32 is hingedly connected with the bottom of the discharge rail 23 through the second connecting shaft 34.

[0057] The mounting groove 311 is accurately designed, and the width of the mounting groove 311 is slightly larger than the width of the connecting rod 32, and the depth of the mounting groove 311 can accommodate the first connecting shaft 33.

[0058] The first connecting shaft 33 penetrates the mounting groove 311, the first connecting shaft 33 is made of stainless steel, and the surface is polished to ensure smooth rotation of the connecting rod 32 around the first connecting shaft 33.

[0059] In this embodiment, when the inclination angle of the discharge rail 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 hingedly connected with the bottom of the discharge rail 23 through the second connecting shaft 34, the rotation of the connecting rod 32 drives the discharge rail 23 to rotate around the connecting point with the base 1, thereby changing the inclination angle of the discharge rail 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 rail 23.

[0060] More preferably, when the discharge rail 23 is adjusted to the appropriate inclination angle, a locking device (such as a bolt, 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 and the mounting block 31 and the discharge rail 23, ensuring that the inclination angle of the discharge rail 23 remains stable during device operation.

[0061] In different production environments and production processes, the requirements for capacitive discharge may be different. The presence of the angle adjusting structure 3 enables the device to flexibly adjust the inclination angle of the discharge rail 23 according to actual production needs, thereby meeting diverse production requirements and improving the market competitiveness of the device.

[0062] Embodiment 3

[0063] As shown in FIG. 3, this embodiment is an improvement based on embodiment 2. Figures 1-7

[0064] In this embodiment, the first connecting shaft 33 is movably arranged in the mounting groove 311, and the first connecting shaft 33 is provided with a locking member 35 for fixing the first connecting shaft 33 on the mounting block 31.

[0065] ​Specifically, in the embodiment, the locking member 35 comprises a mounting ring 351 and a latch 352, the mounting ring 351 is sleeved on the first connecting shaft 33, and the latch 352 is fixed on a side wall of the mounting ring 351; a plurality of clamping holes 312 are arranged on the mounting block 31 and arranged on one side of the mounting groove 311 along the length direction of the mounting groove 311, and the latch 352 is matched with the clamping hole 312.

[0066] An elastic member 36 is arranged 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 opposite to the one end is fixed on one side of the mounting ring 351.

[0067] In the embodiment, when it is needed to adjust the inclination angle of the discharge rail 23, first, the position of the first connecting shaft 33 in the mounting groove 311 is moved to preliminarily change the position and angle of the connecting rod 32. Since the top of the connecting rod 32 is hinged to the bottom of the discharge rail 23, the movement of the first connecting shaft 33 drives the connecting rod 32 to rotate, and then the inclination angle of the discharge rail 23 is changed. After the first connecting shaft 33 is moved to the appropriate position, it needs to be locked. The operator first pulls the mounting ring 351 away from the mounting block 31, at this time the elastic member 36 is stretched, and the latch 352 is pulled out of the original clamping hole 312. Then the first connecting shaft 33 is moved to the target position, and the mounting ring 351 is released. Under the action of the elastic force of the elastic member 36, the mounting ring 351 moves towards the mounting block 31, the latch 352 is inserted into the corresponding clamping hole 312, so that the first connecting shaft 33 is fixed on the mounting block 31, and the accurate locking of the angle is completed. If it is needed to adjust the inclination angle of the discharge rail 23 again subsequently, the above-mentioned operations of pulling out the latch 352 by pulling the mounting ring 351, moving the first connecting shaft 33, and inserting the latch 352 by releasing the mounting ring 351 are repeated.

[0068] Compared with the conventional fixed-angle adjustment mode, the design can more accurately adjust the inclination of the discharge rail 23 according to the characteristics of different capacitors and discharge requirements, so as to optimize the discharge effect of the capacitor and improve the discharge efficiency and quality.

[0069] 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 release the mounting ring 351, and the elastic force of the elastic member 36 can easily realize the insertion and extraction of the latch 352, without the need for complex tools or operation steps, which greatly improves the adjustment efficiency and reduces the labor intensity of the operator.

[0070] Specifically, the elastic member 36 of the application can be a spring.

[0071] Embodiment 4

[0072] As shown in the figure, this embodiment is improved on the basis of Embodiment 1. Figures 1-7

[0073] In this embodiment, the discharge track 23 is provided with support strips 22 on both sides, the length direction of the support strips 22 is the same as that of the baffle, and one side wall of each support strip 22 is connected to one side of the baffle.

[0074] In actual application, the support strips 22 are made of high-strength aluminum alloy material through extrusion molding process, and have good strength and rigidity. The cross-sectional shape of the support strips 22 is rectangular, which is convenient for processing and manufacturing and can provide stable support. The length direction of the support strips 22 is the same as that of the baffle, and one side wall of each support strip 22 is connected to one side of the baffle. The support strips 22 are firmly connected to the baffle through welding to ensure the connection strength and stability between the two. The distance between the two support strips 22 should be greater than the diameter between the pins of the capacitor to avoid the pins from being damaged due to collision with the support strips 22 during the discharge process of the capacitor.

[0075] The support strips 22 are arranged on both sides of the discharge track 23 to provide more stable support for the capacitor. Especially for some large-sized or high-barycenter capacitors, the support strips 22 can effectively prevent the capacitors from rolling over due to shaking during sliding, ensuring that the capacitors can smoothly pass through the discharge track 23 and improving the stability and reliability of the discharge process. The support strips 22 cooperate with the baffle to form a stable guide channel. During the sliding process of the capacitor, the capacitor is constrained by the support strips 22 and the baffle and can only move along the center line of the track, avoiding the capacitor from shifting left and right on the track and ensuring the accurate contact between the pins of the capacitor and the discharge plate 24, thereby improving the discharge efficiency and quality.

[0076] More preferably, the upper surface of the support strip 22 is finely polished to be smooth, which can effectively reduce the friction between the capacitor and the support strip 22. During the sliding process of the capacitor, the contact between the pins and the discharge plate 24 is more stable, reducing the deformation or damage of the pins caused by friction and improving the yield of the capacitor.

[0077] Embodiment 5

[0078] As shown in the figure, this embodiment is improved on the basis of Embodiment 4. Figures 1-7

[0080] Further, the surface of the discharging track 23 is provided with a plurality of clamping grooves 231, and the bottom of the second baffle 25 is provided with a clamping strip 251 which is matched with the clamping grooves 231. The plurality of clamping grooves 231 are arranged along the width direction between the first baffle 21 and the second baffle 25, and the length direction of each clamping groove 231 is the same as the length direction of the second baffle 25. By matching the clamping strip 251 with different clamping grooves 231, the distance between the second baffle 25 and the first baffle 21 can be changed.

[0081] The second baffle 25 of the present application is movably designed, so that the device can easily adapt to electrolytic capacitors of different widths. Whether it is a small capacitor or a large capacitor, the discharging requirement of the capacitor can be met by adjusting the position of the second baffle 25, greatly improving the universality of the device and reducing the cost of purchasing multiple devices for producing capacitors of different specifications.

[0082] Moreover, the second baffle 25 is movably arranged by matching the clamping strip 251 with the clamping grooves 231, and this structure makes it very convenient to disassemble and install the second baffle 25. When maintaining and cleaning 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., ensuring the normal operation of the device.

[0083] Specifically, the clamping groove 231 can be a dovetail groove.

[0085] As shown in the drawings, the present embodiment is improved on the basis of Embodiment 1. Figures 1-7

[0086] In the present embodiment, a buffer plate 26 is arranged at the discharge outlet, one side of the buffer plate 26 is hinged to the discharging track 23, and the surface of the buffer plate 26 is provided with a buffer pad 261.

[0087] The buffer plate 26 is made of lightweight aluminum alloy material with certain strength, and its shape is rectangular and its size is matched with the discharge outlet. One side of the buffer plate 26 is hinged to the edge of the discharge outlet of the discharging 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 movable space for buffering the capacitor.

[0088] The buffer pad 261 is laid on the surface of the buffer plate 26 and is made of soft and elastic rubber material or sponge. The buffer pad 261 is firmly pasted on the buffer plate 26 by strong glue, and its surface has fine protruding texture to increase the friction with the surface of the capacitor and prevent the capacitor from sliding during the buffering process.

[0089] ​The buffer plate 26 and the buffer pad 261 of the 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 of the product.

[0090] 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 devices without a buffer structure, the device of the application significantly reduces the wear of the discharge port components during long-term use, prolonging the overall service life of the device.

[0091] Embodiment 7

[0092] As shown in Figures 1-7 This embodiment is an improvement based on embodiment 1.

[0093] In this embodiment, a plurality of discharge contacts are arranged on the discharge plate 24 along the length direction of the discharge track 23.

[0094] Specifically, the discharge contact of the application adopts a spring needle structure, mainly composed of a needle tube, a spring and a needle head. The needle tube is made of copper alloy material with high conductivity, and its inner wall is plated with silver to reduce resistance and improve conductivity. The spring is placed inside the needle tube and has good elasticity and resilience, which can ensure that the needle head quickly returns to its original position after being pressed. The needle head is made of stainless steel, and its head is polished to ensure good contact with the electrolytic capacitor pin. A plurality of discharge contacts are 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 common pin spacing of electrolytic capacitors to ensure that the capacitor pins can be in contact with each discharge contact in turn during sliding on the track. The discharge contact is fixed on the discharge plate 24 by welding to ensure the stability and conductivity of the connection.

[0095] In this embodiment, by increasing the discharge contact on the basis of the discharge plate 24, the capacitor pins will be in contact with the plurality of discharge contacts on the discharge plate 24 in turn during the sliding of the capacitor. When the capacitor pin contacts the discharge contact, a conductive path is formed between the capacitor pin and the discharge contact, realizing the discharge of the capacitor. As the capacitor continues to slide, its pin will be in contact with different discharge contacts in turn, discharging multiple times to ensure that the residual electricity in the capacitor can be fully discharged. The arrangement of the discharge contact can effectively improve the discharge effect of the device on the capacitor.

[0096] Embodiment 8

[0097] As shown in Figures 1-7 This embodiment provides a capacitor discharge method, which is implemented based on the automatic electrolytic capacitor discharge device as described above.

[0098] Specifically, the capacitor discharging method steps as follows:

[0099] Place the electrolytic capacitor automatic discharging device on a stable workbench, check the angle adjustment structure 3, adjust the discharging track 23 to the appropriate inclination angle by moving the first connecting shaft 33 in the installation slot 311 and fixing it with the locking piece 35. According to the specifications of the capacitor to be discharged, move the second baffle 25 along the clamping slot 231, adjust the distance between the first baffle 21 and the second baffle 25 to just fit the width of the capacitor.

[0100] Place the electrolytic capacitor to be discharged in sequence at the starting end of the discharging track 23. Pay attention to the placement direction of the capacitor, make sure that its pins are facing down, so that they can effectively contact the discharging contacts on the discharging plate 24 during sliding.

[0101] Because the discharging track 23 has a certain inclination angle, the capacitor starts to slide down the track under the action of its own gravity. During the sliding process, the support bars 22 on both sides of the discharging 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, ensuring that it moves smoothly along the center line of the track.

[0102] During the sliding process of the capacitor, its pins will come into contact with the discharging contacts on the discharging plate 24, forming a conductive path and achieving the discharging of the capacitor. As the capacitor continues to slide, its pins will be continuously discharged, ensuring that the residual electricity in the capacitor can be fully discharged.

[0103] When the capacitor completes discharging and slides to the discharge outlet, it first contacts the buffer pad 261 on the surface of the buffer plate 26. The buffer pad 261 deforms elastically, absorbing part of the kinetic energy of the capacitor, while the buffer plate 26 rotates upward around the hinge shaft by a certain angle, further reducing the impact force of the capacitor, allowing the capacitor to be stably stopped on the buffer plate 26.

[0104] After the capacitor is stable on the buffer plate 26, it is taken away from the buffer plate 26 by manual or automatic conveying device for subsequent production process.

[0105] This method can realize the automatic discharging of the capacitor and improve the production efficiency of the capacitor.

[0106] The foregoing is a summary and thus contains only the most basic embodiment. The application can be practiced with modification and alteration and still be within the scope of the application. This summary is not intended to mean that the application described herein will necessarily cover all of the subject matter shown, but it is stated in support of the claims as presented. The applications described herein will now be described with reference to the attached drawings described above. The drawings described herein are intended to be illustrative and not restrictive. For example, the drawings set forth below are provided to illustrate the various embodiments of the application and are not intended to limit the scope of the application.
