Description

Technical Field

[0001] This invention belongs to the field of pressing robot technology, and more specifically, relates to the pressing structure of a rubber stopper based on a capacitor of an industrial robot. Background Technology

[0002] In the field of capacitor manufacturing, rubber stoppers, as sealing and insulating components, are pressed onto capacitors after the liquid injection process. With the widespread application of industrial automation technology in electronic component production lines, the automatic feeding and pressing of rubber stoppers by robotic arms has become the mainstream process direction.

[0003] Existing pressing structures generally adopt a single rigid pressing mode. When the rubber stopper is pressed into the injection hole at room temperature, the hardness of the rubber material itself can easily cause the core to shift and the gap between the stopper and the hole wall to be uneven. Therefore, during the pressing process, it is necessary to soften it by heating to reduce the pressing resistance and avoid core misalignment. Some equipment has a separate heating station to preheat and soften the rubber stopper. However, the heating process and the pressing process are distributed in different stations. The material needs to be repositioned repeatedly during the material transfer process, which not only prolongs the production cycle, but also causes the rubber stopper to gradually cool down and lose heat during the transfer process, so that the actual temperature of the rubber stopper when it arrives at the pressing station is lower than the preset pressing temperature. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a pressing structure for a rubber stopper based on a capacitor of an industrial robot. This solves the problem in the prior art where the existing pressing structure requires preheating and softening the rubber stopper at a heating station before transferring it to the pressing station. During the transfer process, the rubber stopper gradually cools down and loses heat, resulting in the actual temperature of the rubber stopper arriving at the pressing station being lower than the preset pressing temperature.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The rubber stopper heating and softening process is integrated with the pressing and assembly process on the same execution end. Utilizing the switching between the heating and sealing positions of the sealing disc, hot air heating can be directly activated after the rubber stopper is clamped. After heating, the pressing operation is immediately performed, eliminating the need for transfer between the heating and pressing stations. This avoids heat loss from the rubber stopper surface during transfer, ensuring the rubber stopper remains within the appropriate softening temperature range during pressing. This reduces problems such as increased stopper hardness and increased pressing resistance due to temperature drops, and minimizes assembly defects such as core misalignment and uneven clearance between the stopper and the injection hole. During heating, the hot air is ejected through the heating hole 306 and diffuses evenly along the heating channels between the contact blocks towards the top surface of the rubber stopper, ensuring uniform heating and further improving the consistency of the softening effect.

[0016] 2. By switching the locking block between the locked and unlocked positions, the clamping plate can be flexibly switched between two working modes: rigid connection and floating sliding, adapting to the force requirements of different operation stages. During the material transfer and large-stroke alignment stages, the locking block is in the locked position, and the clamping plate and lifting frame are rigidly connected as one unit, ensuring structural stability and accurate alignment during material transfer. During the pressing operation, the locking block switches to the unlocked position, and the clamping plate can make a small range of floating displacement along the sliding column. With the help of high-pressure gas drive, it can achieve flexible pressing, buffering the impact force at the moment of pressing and avoiding deformation of the capacitor shell or damage to the rubber plug caused by rigid pressing. After pressing is in place, the locking block can switch back to the locked position to form a rigid pressure holding state, maintaining a stable pressing depth and pressing force, ensuring the sealing performance of the rubber plug after pressing, and improving the pressing consistency during mass production.

[0017] 3. Multiple functions, including clamping and transferring materials, hot air heating, and pressing assembly, are integrated into a single pressing actuator. This eliminates the need for multiple independent workstations on the production line, reducing overall equipment space requirements and simplifying production line layout. The pneumatic system utilizes a three-way solenoid valve to achieve single-chamber reuse. The same heating chamber can be used for both heating with atmospheric pressure gas to generate hot air from the heating module and pressing with high-pressure gas to drive the pressure plate displacement. This eliminates the need for separate drive and heating air circuits, reducing the number of external pipelines and making the overall structure more compact. A sealing block on the outside of the transmission cavity seals gaps, preventing heat loss due to hot air leakage from the transmission position during heating and preventing external dust and debris from entering the transmission pair and causing jamming and wear, thus improving equipment stability and extending its service life.

Detailed Implementation

[0020] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solutions of the present invention, but should not be used to limit the scope of protection of the present invention.

[0021] Example:

[0022] As attached Figures 1 to 12 As shown: This invention provides a pressing structure for a rubber stopper of a capacitor based on an industrial robot, comprising: a longitudinal track support 101 and a transverse track support 102, wherein the longitudinal track support 101 is movably mounted on top of the transverse track support 102, and a pressing assembly is movably mounted on top of the longitudinal track support 101. The pressing assembly is used to press and assemble the rubber stopper onto the capacitor; the pressing assembly includes two sets of locking blocks 201 located in locked or unlocked positions, a lifting frame 202 is movably mounted on top of the longitudinal track support 101, and a clamping plate 203 is disposed below the lifting frame 202. The top of the clamping plate 203 is provided with two sets of locking sleeves 204, and the bottom of the clamping plate 203 is provided with a material transfer robot for clamping and transferring rubber plugs. When the two sets of locking blocks 201 are in the locked position, the top of the two sets of locking sleeves 204 are inserted into the lifting frame 202, and the two sets of locking blocks 201 are respectively inserted into the two sets of locking sleeves 204. The clamping plate 203 is fixed to the bottom of the lifting frame 202. When the two sets of locking blocks 201 are in the unlocked position, the locking blocks 201 are not inserted into the locking sleeves 204, and the clamping plate 203 is vertically slidably disposed at the bottom of the lifting frame 202. The material handling robot includes a sealing plate 301 located at a heating or sealing position, a lifting sleeve 302 inside a lifting frame 202, a through heating chamber at the top of the lifting sleeve 302, a heating module 303 for heating the internal gas inside the heating chamber, a material handling plate 304 at the bottom of the pressing plate 203, a pressing end plate 305 at the bottom of the material handling plate 304, and a heating hole 306 at the center of the bottom of the pressing end plate 305. The heating chamber, the heating hole 306, and the sealing... The sealing discs 301 are coaxially distributed. When the sealing discs 301 are in the heating position, they retract from the heating holes 306, allowing the top of the heating holes 306 to communicate with the heating chamber. The heating module 303 heats the gas in the heating chamber, and the heated gas flows downward along the heating chamber and is blown out through the heating holes 306 to the rubber plug for heating. When the sealing discs 301 are in the sealing position, they are inserted into the heating holes 306, and the top of the heating holes 306 is not connected to the heating chamber. Both the material handling robot and the pressing assembly are connected to an external control terminal. The rubber stopper heating and softening process and the pressing and assembly process are integrated into the same execution end. Relying on the switching between the heating position and the sealing position of the sealing plate 301, hot air heating can be turned on directly after the rubber stopper is clamped. After heating, the pressing operation is performed immediately, eliminating the transfer link between the rubber stopper and the pressing position. This avoids heat loss from the surface of the rubber stopper during the transfer process and ensures that the rubber stopper is always in the appropriate softening temperature range during pressing. It reduces the problems of the stopper hardness rebound and the increase of pressing resistance caused by the temperature drop, and reduces assembly defects such as core packing misalignment and uneven gap between the stopper and the injection hole. During the heating process, hot air is sprayed out through the heating hole 306 to heat the rubber stopper and soften it.

[0023] The pressing assembly also includes a first electric telescopic rod 205 for driving the sealing disc 301 to move between the heating position and the sealing position. The first electric telescopic rod 205 is electrically connected to an external control terminal. A first mounting hole is opened at the bottom of the pressing plate 203, and a mounting sleeve 230 is inserted into the first mounting hole. The outer wall of the mounting sleeve 230 is fixed to the inner wall of the first mounting hole. The first electric telescopic rod 205 is installed in the internal cavity of the mounting sleeve 230. The telescopic rod at the bottom end of the first electric telescopic rod 205 is connected to the sealing disc 301. 01 Top surface connection, the telescopic rod of the first electric telescopic rod 205 performs telescopic action, thereby driving the sealing plate 301 to move up and down along the axial direction, realizing the switching between the heating position and the sealing position. The top of the lifting sleeve 302 is equipped with a three-way solenoid valve 206. The valve seat of the three-way solenoid valve 206 is fixed on the top end face of the lifting sleeve 302. The valve port at the bottom of the three-way solenoid valve 206 is connected to the inside of the heating chamber. The two sets of valve ports at the top of the three-way solenoid valve 206 are respectively connected to the external air intake equipment and the air suction equipment.

[0024] In this embodiment, when the equipment enters the rubber stopper heating process, the external control terminal controls the first electric telescopic rod 205 to extend the telescopic rod and push the sealing disc 301 downward to the heating position. At this time, the sealing disc 301 is completely withdrawn from the heating hole 306, and the top of the heating hole 306 is fully connected to the heating chamber. The three-way solenoid valve 206 is switched to the passage connected to the external air intake device, and the external atmospheric pressure gas is continuously introduced into the heating chamber. The heating module 303 is started, and the heating module 303 heats the gas flowing in the heating chamber. The heated gas flows downward along the heating chamber and is blown out through the heating hole 306 to the top surface area of ​​the rubber stopper. When the heating process is completed, the heating module 303 is turned off, the first electric telescopic rod 205 retracts the telescopic rod and pulls the sealing disc 301 upward to the sealing position. The side wall of the sealing disc 301 is attached to the inner wall of the heating hole 306, blocking the gas flow path between the heating chamber and the heating hole 306. When the locking block 201 is in the unlocked position, the three-way solenoid valve 206 switches to the high-pressure gas supply passage connected to the external air intake device. High-pressure gas continuously fills the heating chamber, and the gas pressure acts on the top surface of the sealing plate 301 and the pressing end plate 305. The pressing plate 203 moves down synchronously, and the moving pressing end plate 305 applies a pressing force to the rubber plug. At the same time, the compressibility of the gas is utilized to provide a buffer margin during pressing and absorb the instantaneous impact force during the pressing process. After the pressing and holding pressure is completed, the three-way solenoid valve 206 switches to the passage connected to the external air intake device. The air intake device draws gas from the heating chamber to create a negative pressure in the chamber, which drives the pressing plate 203 and the pressing end plate 305 to move upward.

[0025] Multiple sets of contact blocks 207 are provided at the bottom of the pressing end plate 305. The multiple sets of contact blocks 207 are evenly arranged around the bottom surface of the pressing end plate 305. The bottom of the multiple sets of contact blocks 207 is used to directly contact the top surface of the rubber stopper to transmit the pressing force. There are gaps between the multiple sets of contact blocks 207 to form a heating channel. The heating channel extends radially from the center to the outside. In this embodiment, when the sealing plate 301 is in the heating position, the sealing plate 301 is located above the center of the heating channel. The inner end of the heating channel is connected to the bottom opening of the heating hole 306. After the hot air jet from the heating hole 306 contacts the top surface of the rubber stopper, it diffuses along the gap of the heating channel to the circumferential edge of the rubber stopper, so that the central area and the edge area of ​​the top surface of the rubber stopper can be in contact with the hot air jet, so as to achieve uniform heating of the entire rubber stopper and avoid local temperature differences from affecting the softening effect.

[0026] A lifting slide cylinder 209 is slidably inserted inside the lifting sleeve 302. The bottom end of the lifting slide cylinder 209 and the bottom end of the lifting frame 202 are both connected to the second mounting plate 210. The outer wall of the lifting slide cylinder 209 fits against the inner wall of the lifting sleeve 302 and can slide linearly along the axial direction of the lifting sleeve 302. This is used to guide the second mounting plate 210 and the lifting frame 202 to perform lifting displacement as a whole and to limit horizontal deviation during the lifting process. Four sets of sliding columns 211 are provided on the top of the pressure plate 203. The four sets of sliding columns 211 are evenly distributed around the top surface of the pressure plate 203. The bottom of the second mounting plate 210 is provided with openings corresponding to the four sets of sliding columns 211. Four sets of first sliding holes 212 and four sets of sliding posts 211 are respectively slidably inserted into the four sets of first sliding holes 212. The outer wall of the sliding post 211 is in contact with the inner wall of the first sliding hole 212 and can slide along the axial direction of the channel. Each of the four sets of sliding posts 211 is provided with a limit ring at the top. The outer diameter of the limit ring is larger than the inner diameter of the first sliding hole 212, which is used to limit the downward sliding stroke of the sliding post 211 and prevent the sliding post 211 from falling out of the first sliding hole 212. Each of the four sets of sliding posts 211 is fitted with a floating spring 213 on the outside. The top of the floating spring 213 abuts against the bottom surface of the second mounting plate 210, and the bottom of the floating spring 213... The floating spring 213 abuts against the top surface of the pressure plate 203 and provides an upward restoring force for the pressure plate 203. Two sets of sliding seats 214 are provided on the top of the second mounting plate 210, symmetrically arranged on both sides of the top surface of the second mounting plate 210. Each set of sliding seats 214 has a second sliding hole 215 on one side. Two sets of locking blocks 201 slide through the two sets of second sliding holes 215 respectively. A second electric telescopic rod 216 is provided on the top of the sliding seat 214 to drive the locking blocks 201 to move between the locked and unlocked positions. The telescopic rod of the second electric telescopic rod 216... The end of the locking block 201 is connected to one end of the locking sleeve 204. The second electric telescopic rod 216 is electrically connected to an external control terminal to control the second electric telescopic rod 216 to perform telescopic movements, thereby driving the locking block 201 to slide in the second sliding hole 215 to realize the switching of work positions. A third sliding hole 218 is opened on one side of the locking sleeve 204 corresponding to the locking block 201. The inner diameter of the third sliding hole 218 is the same as the inner diameter of the second sliding hole 215. The top of the second mounting plate 210 is provided with two sets of through slots corresponding to the two sets of locking sleeves 204. The cross-sectional dimensions of the through slots are adapted to the cross-sectional dimensions of the locking sleeves 204, allowing the locking sleeves 204 to pass through.

[0027] In this embodiment, when the locking block 201 is in the locked position, the two sets of locking sleeves 204 extend upward through the two sets of through slots to the top surface of the second mounting plate 210. The second sliding hole 215 and the third sliding hole 218 are located on the same axis. The locking block 201 passes through the second sliding hole 215 and the third sliding hole 218. The outer wall of the locking block 201 is simultaneously attached to the inner wall of the two channels, restricting the axial displacement of the locking sleeve 204. This is used to rigidly connect the pressing plate 203 and the second mounting plate 210 into one unit, so that the pressing plate 203 can move up and down synchronously with the second mounting plate 210 and the lifting frame 202, and there will be no relative displacement between the two.

[0028] Specifically, the rubber plug is moved laterally from the material handling station to the pressing station. During this process, the locking block 201 remains in the locked position, and the pressing plate 203 and the second mounting plate 210 maintain a rigid connection. The pressing plate 203 will not sway up and down during the material transfer process, and the rubber plug held by the material transfer robot can maintain a stable posture and will not shift or fall off due to shaking, ensuring the accuracy of the material transfer alignment. When the locking block 201 is in the unlocked position, the locking sleeve 204 is not inserted into the through groove, and the top of the locking sleeve 204 is located below the second mounting plate 210. The second sliding hole 215 and the third sliding hole 218 are not located on the same axis. The locking block 201 is only inserted into the second sliding hole 215. The locking block 201 does not form an axial constraint on the locking sleeve 204. It is used to release the rigid constraint between the pressing plate 203 and the second mounting plate 210, so that the pressing plate 203 can slide axially relative to the first sliding hole 212 through the sliding column 211.

[0029] Furthermore, after the pressing assembly moves to directly above the pressing station, the external control terminal controls the second electric telescopic rod 216 to extend the telescopic rod and push the locking block 201 from the locked position to the unlocked position. The locking block 201 gradually disengages from the third sliding hole 218 and completely enters the second sliding hole 215. At this time, the rigid connection between the pressing plate 203 and the second mounting plate 210 is released. When high-pressure gas is subsequently introduced to drive the pressing plate 203 to move downward, the pressing plate 203 can slide downward independently without causing the second mounting plate 210 and the lifting frame 202 to move synchronously. The pressing assembly is located at the pressing station. The second electric telescopic rod 216 is activated to extend the telescopic rod to move the locking block 201 from the locked position to the unlocked position and disengage it from the third sliding hole 218, so that the locking block 201 only passes through the second sliding hole 215. The pressing plate 203 slides downward along the first sliding hole 212 through the sliding column 211, and the floating spring... Spring 213 compression is a preparatory step for the pressing operation. After the rigid constraint is released, the pressing plate 203 has the ability to float and can be flexibly pressed in by air pressure, avoiding the impact of large-stroke rigid pressing on the capacitor shell. When pressing the rubber plug, the pressing plate 203 rises along the first sliding hole 212 through the sliding column 211 during the pressing process, so that the locking sleeve 204 passes through the through groove on the second mounting plate 210. The second sliding hole 215 and the third sliding hole 218 are coaxial. The second electric telescopic rod 216 is activated to retract the telescopic rod, and the locking block 201 moves from the unlocked position to the locked position. The locking block 201 passes through the second sliding hole 215 and the third sliding hole 218, so that the second mounting plate 210 and the pressing plate 203 are fixedly connected. This step is the pressure holding and locking action after pressing in place. The pressing depth is maintained by rigid locking to prevent the rubber plug from rebounding and causing incomplete pressing.

[0030] Specifically, the rubber stopper is made of butyl rubber, which undergoes a certain elastic deformation under pressure. After being pressed into the injection hole, it tends to rebound outwards. If the pressure is released directly after pressing, the rubber stopper may rebound beyond the preset depth, affecting the sealing performance. By switching the locking block 201 to the locked position, the pressing plate 203 and the second mounting plate 210 are rigidly fixed, which can maintain a stable pressing depth during the pressure holding period, counteract the rebound force of the rubber stopper, and ensure the positional accuracy of the rubber stopper after pressing. Furthermore, by switching the locking block 201 between the locked and unlocked positions, the pressing plate 203 can be flexibly switched between two working modes: rigid connection and floating sliding, adapting to different operating stages. During the material transfer and large stroke alignment stages, the locking block 201 is in the locked position, and the pressing plate 203 and the lifting frame 202 are rigidly connected to each other to ensure structural stability and accurate alignment during the material transfer process. During the pressing operation, the locking block 201 switches to the unlocked position, and the pressing plate 203 can make a small range of floating displacement along the sliding column 211. With the help of high-pressure gas drive, flexible pressing is achieved, buffering the impact force at the moment of pressing and avoiding rigid hard pressing that could cause deformation of the capacitor shell or damage to the rubber plug. After pressing is in place, the locking block 201 can switch back to the locked position to form a rigid pressure holding state, maintaining a stable pressing depth and pressing force, ensuring the sealing performance of the rubber plug after pressing, and improving the pressing consistency during mass production.

[0031] Two sets of longitudinal slide rails 103 are provided on the top of the longitudinal track support 101. The two sets of longitudinal slide rails 103 are arranged parallel to each other along the length of the longitudinal track support 101. The material transfer support 219 is slidably connected to the two sets of longitudinal slide rails 103 by two sets of first sliders respectively. The top surface of the first slider is fixed to the bottom surface of the material transfer support 219. A material transfer mounting frame 220 is provided on one side of the material transfer support 219. The material transfer mounting frames 220 are vertically distributed. A mounting base 221 and a first mounting plate 222 are provided on one side of the material transfer mounting frame 220. The mounting base 221 is located below the first mounting plate 222. The top of the lifting sleeve 302 is connected to the first mounting plate 222. A second mounting hole is provided at the top corresponding to the heating chamber. A three-way solenoid valve 206 is installed in the second mounting hole. The bottom valve port of the three-way solenoid valve 206 is aligned and connected with the top opening of the heating chamber, allowing the external air passage to be directly connected to the interior of the heating chamber. The bottom end of the lifting sleeve 302 is connected to the mounting base 221. The mounting base 221 provides support and fixation for the lower part of the lifting sleeve 302, ensuring that the lifting sleeve 302 always remains vertical, providing a stable guiding reference for the sliding of the lifting slide 209. A belt drive structure 223 is provided on one side of the lifting frame 202 and is connected to a protective cover 224 through two sets of brackets. The belt drive structure 223 is located inside the protective cover 224 to prevent operation. To prevent the belt from rubbing against surrounding components and improve equipment operation safety, a lifting motor 225 is installed on one side of the protective cover 224. The lifting motor 225 is electrically connected to an external control terminal. The main shaft of the lifting motor 225 passes through the side wall of the protective cover 224 and is connected to the drive wheel of the belt drive structure 223. When the lifting motor 225 is running, it can drive the drive wheel to rotate, thereby driving the belt to circulate vertically. A clamping plate 226 is installed on one side of the material transfer mounting frame 220. The clamping plate 226 is fixedly connected to one side of the belt of the belt drive structure 223. When the belt is running, the clamping plate 226 can drive the material transfer mounting frame 220 and the lifting frame 202 to generate relative displacement. The lifting motor 225... 5 is used to drive the lifting frame 202 to lift via the belt drive structure 223, so as to realize the large stroke vertical displacement of the pressing component and meet the height alignment requirements of different work stations. A detection seat 227 is provided on one side of the material transfer mounting frame 220. The detection seat 227 extends vertically and is fixed to the side wall of the material transfer mounting frame 220. A sensing end 228 is provided on one side of the lifting frame 202. The sensing end 228 moves vertically synchronously with the lifting frame 202. Infrared sensors 229 are respectively provided at the top and bottom of the detection seat 227. The detection end of the infrared sensor 229 faces the sensing end 228. The infrared sensor 229 is used to detect the relative distance between the sensing end 228 and the detection seat 227.

[0032] In this embodiment, the external control terminal controls the lifting motor 225 to move the clamping plate 226 through the belt drive structure 223, which further causes the lifting frame 202, the lifting slide 209, and the material transfer robot to rise and fall along the lifting sleeve 302. The external control terminal can control the rate and direction of the lifting displacement by adjusting the speed and direction of the lifting motor 225. The outer wall of the lifting slide 209 is in contact with the inner wall of the lifting sleeve 302 and slides axially along the inner wall of the sleeve, providing auxiliary guidance for the entire lifting process, avoiding shaking of the lifting frame 202 during movement, ensuring the verticality of the pressing end plate 305, and keeping the rubber plug pressing direction consistent with the axis of the capacitor injection hole.

[0033] Specifically, the external control terminal first controls the lifting motor 225 to rotate forward, driving the belt to move the clamping plate 226 and the lifting frame 202 downward. The lifting slide 209 slides smoothly down along the inner wall of the lifting sleeve 302, and the material transfer robot moves down to the material picking height. After the rubber plug is picked up, the control module controls the lifting motor 225 to rotate in reverse, driving the lifting frame 202 to move up to the clearance height. After the workstation switch is completed, the lifting motor 225 is controlled to rotate forward again to move the pressing component down to the pressing station height. The displacement rate of the entire lifting process remains stable, and the rubber plug will not fall off the material transfer claw 307 due to the impact of starting and stopping.

[0034] The material handling robot also includes multiple sets of material handling claws 307 for gripping rubber plugs. The bottom end of the mounting sleeve 230 is connected to the material handling disk 304. The bottom of the material handling disk 304 has a rotating groove 308, which is a circular groove and is coaxially arranged with the material handling disk 304. A rotating disk 309 is rotatably arranged in the rotating groove 308. Multiple sets of sliding grooves 310 are formed around the rotating groove 308. The sliding grooves 310 extend along the radial direction of the material handling disk 304. Sliding blocks 311 are slidably arranged in each set of sliding grooves 310. The sliding blocks 311 can reciprocate along the radial direction of the sliding grooves 310. The ends of the sliding blocks 311 away from the rotating disk 309 are fixedly connected to the material handling claws 307. 07 moves synchronously with the sliding block 311. The spacing between the multiple sets of transfer claws 307 is adjusted by the radial sliding of the sliding block 311 to achieve the clamping and release of the rubber stopper. The bottom of the transfer disk 304 is connected to the pressing end disk 305 through multiple sets of limiting blocks 312. The multiple sets of limiting blocks 312 are evenly distributed in the circumference, and their upper and lower ends are fixed to the bottom surface of the transfer disk 304 and the top surface of the pressing end disk 305, respectively, to maintain the set spacing between the transfer disk 304 and the pressing end disk 305. The multiple sets of limiting blocks 312 are spaced apart to form a transmission cavity 313. The transmission cavity 313 provides the movement space for the transmission action of the connecting rod 315 and the sliding block 311. The external opening of the multiple sets of transmission cavities 313 is provided with a sealing block. 314, the sealing block 314 is located at the outer port of the transmission cavity 313, separating the transmission structure from the external environment. The sealing block 314 is used to seal the transmission cavity 313 to prevent the leakage of hot gas from the heated rubber plug, avoiding the hot gas flow into the transmission structure and causing the transmission components to age due to heat. At the same time, it blocks external dust and rubber debris from entering the transmission cavity 313, ensuring the cleanliness and smooth operation of the transmission pair. The bottom of the sliding block 311 is provided with a connecting rod 315 corresponding to the transmission cavity 313. One end of the connecting rod 315 is rotatably connected to the bottom of the sliding block 311, and the other end of multiple sets of connecting rods 315 are rotatably connected to the rotating disk 309. The connecting rod 315 moves with the rotation of the rotating disk 309, thereby pulling or pushing the sliding block 311. 11. The rotating disk 309 slides radially along the sliding groove 310. A through hole is provided at the top of the rotating disk 309, and an internal gear ring 316 is provided in the through hole. A transfer motor 317 for driving the rotating disk 309 to rotate is provided in the mounting sleeve 230. The transfer motor 317 is electrically connected to an external control terminal. The body of the transfer motor 317 is fixed to the inner wall of the mounting sleeve 230, and the output shaft faces the rotating disk 309 downward. A gear 318 is provided on the main shaft of the transfer motor 317. The gear 318 meshes with the internal gear ring 316. When the transfer motor 317 is running, it drives the gear 318 to rotate. Through the meshing transmission between the gear 318 and the internal gear ring 316, the power is transmitted to the rotating disk 309, driving the rotating disk 309 to rotate around the axis.

[0035] In this embodiment, when the external control terminal controls the transfer motor 317 to rotate forward, the gear 318 drives the internal gear ring 316 and the rotating disk 309 to rotate forward. When the rotating disk 309 rotates, it pulls the outer end of the connecting rod 315 to retract towards the center. The other end of the connecting rod 315 pulls the sliding block 311 to slide along the sliding groove 310 towards the center, driving multiple sets of transfer claws 307 to retract inward synchronously, reducing the distance between the multiple sets of transfer claws 307 to clamp and fix the rubber plug. The external control terminal controls the transfer motor 317 to rotate forward, driving multiple sets of transfer claws 307 to retract inward synchronously. The inner side of the claw body fits against the circumferential outer wall of the rubber plug, thus clamping and fixing the rubber plug. The rubber plug is firmly clamped. After clamping, the lifting frame 202 moves the rubber plug upward. The entire material handling process does not require manual assistance. When the material transfer motor 317 rotates in the opposite direction, the gear 318 drives the internal gear ring 316 and the rotating disk 309 to rotate in the opposite direction. When the rotating disk 309 rotates in the opposite direction, it pushes the outer end of the connecting rod 315 to unfold outward. The other end of the connecting rod 315 pushes the sliding block 311 to slide outward along the sliding groove 310, which drives multiple sets of material transfer claws 307 to open outward in sync to release the rubber plug and complete the pressing. The opening action and the closing action have the same path, which can smoothly release the clamping constraint on the rubber plug and avoid the rubber plug being bumped during release, causing positional displacement.

[0036] An electric transfer telescopic cylinder 104 is installed on the top of the longitudinal track support 101. One end of the telescopic rod of the electric transfer telescopic cylinder 104 is connected to the side of the transfer support 219. The extension direction of the telescopic rod is parallel to the extension direction of the longitudinal slide rail 103, and is used to drive the transfer support 219 to move along the longitudinal slide rail 103. After the equipment completes the gripping of the rubber plug at the loading station, the external control terminal controls the electric transfer telescopic cylinder 104 to extend the telescopic rod and push the transfer support 219 to move along the longitudinal slide rail 103 towards the pressing station. After reaching the designated position, the electric transfer telescopic cylinder 104... The movement is stopped and locked, allowing the material transfer bracket 219 to remain stably positioned above the pressing station. The top of the transverse track bracket 102 is equipped with two sets of transverse slide rails 105 and two sets of connecting blocks 106. The two sets of transverse slide rails 105 are arranged parallel to each other along the length of the transverse track bracket 102. The two sets of connecting blocks 106 are fixed at both ends of the transverse track bracket 102. The bottom of the transverse transfer plate 107 is slidably connected to the two sets of transverse slide rails 105 via two sets of second sliders. The bottom of the longitudinal track bracket 101 is fixedly connected to the top surface of the transverse transfer plate 107, moving with the transverse transfer plate... 107 synchronously performs lateral displacement to achieve lateral station switching of the entire pressing assembly. A toothed belt 108 is provided between the two sets of connecting blocks 106. The two ends of the toothed belt 108 are fixed to the two connecting blocks 106 respectively. The belt is kept taut and parallel to the transverse slide rail 105. A toothed pulley 109 and two sets of driven pulleys 110 are provided at the bottom of the transverse plate 107 corresponding to the toothed belt 108. The toothed pulley 109 is located between the two sets of driven pulleys 110. The toothed belt 108 is wound around the toothed pulley 109 and the two sets of driven pulleys 110 respectively. On the driven pulley 110, the meshing area between the toothed belt 108 and the toothed pulley 109 is sufficient to avoid tooth skipping during transmission. A transverse motor 111 is installed on the top of the transverse plate 107. The body of the transverse motor 111 is fixed on the top surface of the transverse plate 107. The main shaft of the transverse motor 111 passes downward through the through hole of the transverse plate 107 and connects to the toothed pulley 109. When the transverse motor 111 is running, it can drive the toothed pulley 109 to rotate. Through the meshing action of the wheel teeth and belt teeth, the transverse plate 107 moves along the extension direction of the toothed belt 108.

[0037] In this embodiment, the transverse motor 111 is started to rotate the toothed pulley 109, causing the transverse plate 107 and the longitudinal track support 101 to move along the transverse slide rail 105. When the transverse motor 111 rotates in the right direction, the transverse plate 107 moves to one side, and when it rotates in the opposite direction, the transverse plate 107 moves to the other side. The electric transfer telescopic cylinder 104 is started to push the transfer support 219 and the transfer mounting frame 220 to move along the longitudinal slide rail 103. The telescopic rod of the electric transfer telescopic cylinder 104 extends out to move the corresponding transfer support 219 to the pressing station, and retracts the telescopic rod to move the corresponding transfer support 219 to the material picking station.

[0038] The specific usage and function of this embodiment are as follows: During use, the external control terminal controls the transverse motor 111 to drive the toothed pulley 109 to rotate. Through the meshing transmission between the toothed belt 108 and the driven pulley 110, the transverse plate 107 moves laterally along the transverse slide rail 105 at the top of the transverse track bracket 102. Simultaneously, it drives the longitudinal track bracket 101 to complete the transverse alignment with the entire pressing assembly. Two sets of connecting blocks 106 fix the two ends of the toothed belt 108 to ensure belt tension and prevent tooth skipping during the transmission process. At the same time, the external control terminal controls the telescopic rod of the electric transfer telescopic cylinder 104 to extend and retract, driving the transfer bracket 219 to move longitudinally along the longitudinal slide rail 103 at the top of the longitudinal track bracket 101. This, combined with the transverse movement, moves the pressing assembly and the transfer robot to the top of the material picking station.

[0039] Upon reaching the material handling station, the external control terminal controls the lifting motor 225 to drive the belt drive structure 223 to operate. Through the clamping plate 226, the lifting frame 202 and the lifting slide 209 slide downwards along the lifting sleeve 302, causing the material handling robot to descend to the rubber stopper handling height. The detection seat 227 on the side of the material handling mounting frame 220 senses the position of the sensing end 228 on the side of the lifting frame 202 in real time through infrared sensors 229 at the top and bottom. During material handling, the material handling motor 317 inside the mounting sleeve 230 rotates forward... The operation drives the gear 318 to rotate, which in turn drives the rotating disk 309 to rotate in the rotating groove 308 at the bottom of the transfer disk 304 through meshing with the inner gear ring 316 of the rotating disk 309. The rotating disk 309 pulls the corresponding sliding block 311 along the sliding groove 310 towards the center through multiple sets of connecting rods 315, which simultaneously drives multiple sets of transfer claws 307 to retract inward, clamping the rubber plug from the periphery to complete the material removal. The synchronous action of multiple sets of transfer claws 307 can ensure that the rubber plug is clamped and centered, avoiding skewing during subsequent pressing.

[0040] After material retrieval is completed, the lifting motor 225 reverses and drives the lifting frame 202 and the rubber plug to move up to the clearance height. The transverse motor 111 and the electric material transfer telescopic cylinder 104 work together to move the pressing assembly to the top of the pressing station. After reaching the pressing station, the external control terminal controls the second electric telescopic rod 216 to extend the telescopic rod and push the locking block 201 to slide along the second sliding hole 215 on the sliding seat 214, switching from the locked position to the unlocked position, so that the locking block 201 disengages from the third sliding hole 218 on the side of the locking sleeve 204, releasing the rigid connection between the pressing plate 203 and the second mounting plate 210. At this time, the pressing plate 203 can float axially along the first sliding hole 212 on the second mounting plate 210 through the four sets of sliding columns 211 at the top. The floating spring 213 on the outside of the sliding column 211 provides an upward reset force for the pressing plate 203.After unlocking, the external control terminal activates the first electric telescopic rod 205. The first electric telescopic rod 205 extends and pushes the sealing disc 301 downward from the sealing position to the heating position, so that the heating hole 306 in the center of the pressing end disc 305 is connected to the heating chamber inside the lifting sleeve 302. Then, the three-way solenoid valve 206 switches to the passage connected to the external air intake device, and normal pressure gas is introduced into the heating chamber. At the same time, the heating module 303 in the heating chamber is activated to heat the gas. The heated hot air is blown through the heating hole 306 to the top surface of the rubber plug clamped below, and the hot air travels along the multiple sets of contact blocks 207 at the bottom of the pressing end disc 305. The heating flow channel diffuses circumferentially to the rubber stopper, causing the rubber stopper to soften evenly with heat, reducing subsequent pressing resistance, and minimizing assembly defects such as core packing misalignment and uneven clearance between the stopper body and the injection hole. A transmission cavity 313 is formed between the transfer plate 304 and the pressing end plate 305 through multiple sets of limiting blocks 312. A sealing block 314 on the outside of the transmission cavity 313 seals the gap, preventing hot air from entering the transmission parts and causing component aging, while also blocking dust and debris to ensure smooth transmission. After heating reaches the preset conditions, the heating module 303 stops working, and the first electric telescopic rod 205 retracts, pulling the sealing plate 301 upwards to the sealing position. The sealing disc 301 is inserted into the heating hole 306 to block the gas path, preventing subsequent high-pressure gas leakage and ensuring stable pressing force. Then, the three-way solenoid valve 206 switches to the high-pressure gas supply path, introducing high-pressure gas into the heating chamber. The high-pressure gas acts on the top surface of the pressing plate 203, pushing the pressing plate 203 to slide downward along the sliding column 211, causing the pressing end disc 305 and the contact block 207 to move downward synchronously. At the same time, it can buffer the impact force at the moment of pressing, pressing the rubber plug into the capacitor injection hole. During the pressing process, the pressing plate 203 continuously moves upward relative to the second mounting plate 210, causing the locking sleeve 204 to pass upward through the second mounting plate 210. When the infrared sensor 229 detects that the sensing end 228 has reached the preset pressing depth position, the axes of the second sliding hole 215 and the third sliding hole 218 coincide. The external control terminal controls the second electric telescopic rod 216 to retract, pushing the locking block 201 from the unlocked position to the locked position, so that the locking block 201 simultaneously enters the interior of the second sliding hole 215 and the third sliding hole 218, rigidly connecting the pressing plate 203 and the second mounting plate 210 into one, maintaining the current pressing depth for pressure retention, offsetting the rebound force of the rubber plug after being pressed, ensuring the consistent pressing depth of the rubber plug, and improving the sealing performance and batch pressing consistency.

[0041] After the pressure holding is completed, the transfer motor 317 rotates in reverse, driving the rotating disk 309 to rotate in reverse through the gear 318 and the internal gear ring 316. The connecting rod 315 pushes the sliding block 311 and the transfer claw 307 to open outward synchronously, releasing the clamping of the rubber plug. Then, the three-way solenoid valve 206 switches to the passage connected to the external air suction equipment, drawing gas from the heating chamber to form a negative pressure. With the reset force of the floating spring 213, the pressing plate 203 slides upward to reset. The locking block 201 switches back to the unlocked position. The lifting motor 225 rotates in reverse, driving the lifting frame 202 to rise to the clearance height. The horizontal movement motor 111 and the electric transfer telescopic cylinder 104 cooperate again to move the pressing assembly to the next pressing station. The above operation process is repeated to realize the continuous automated pressing of the capacitor rubber plug.
