Description

Technical Field

[0001] This invention relates to the field of lithium battery processing equipment technology, and in particular to a burr removal device for lithium battery processing. Background Technology

[0002] After lithium battery-related tubing is cut, stamped, or machined, burrs easily form on the inner walls of its ports. If these burrs are not removed in time, they will not only affect the sealing and connection stability during subsequent assembly, but may also scratch mating components. Therefore, it is usually necessary to deburr the inner walls of the tubing ports.

[0003] Most deburring devices in the prior art use grinding wheels or grinding heads to grind the pipes. For example, Chinese invention patent CN108214166A discloses a deburring device for lithium battery processing, which uses a grinding structure to grind the workpiece.

[0004] However, existing technologies for removing burrs from the inner ends of pipe fittings typically require a separate internal grinding drive mechanism. This mechanism uses telescopic or pneumatic components to drive the internal grinding structure into the pipe fitting for grinding. This not only results in a complex overall structure but also lacks coordination between the internal grinding mechanism and the workpiece conveying mechanism. After processing a single workpiece, it is usually necessary to disconnect the internal grinding structure from the pipe fitting before unloading and reloading, leading to cumbersome loading and unloading processes, long workpiece processing intervals, and reduced overall processing efficiency. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a burr removal device for lithium battery processing, so as to solve the problems in the prior art that require setting up an independent inner wall grinding drive mechanism and the long workpiece processing interval when deburring the inner port of the pipe fitting.

[0006] To achieve the above objectives, the present invention provides a burr removal device for lithium battery processing, including a rotating base and two sets of clamping assemblies disposed on the top of the rotating base, wherein a grinding device is disposed on one side of the rotating base.

[0007] The clamping assembly includes an adjustable base and clamping plates disposed at both ends of the adjustable base. A rotating support ring is rotatably disposed on the side of the clamping plate near the pipe.

[0008] The bottom of the rotating base is provided with a pressurizing component for inflating and depressurizing the flexible airbag, and the clamping component is connected to the pressurizing component; the pressurizing component can alternately inflate and depressurize the two sets of clamping components as the rotating base rotates.

[0009] The rotating base can drive two sets of clamping components to switch between the grinding station and the material handling station, so that the flexible airbag in the grinding station expands and fits against the inner wall of the pipe to grind the inner wall of the pipe, and the flexible airbag in the material handling station contracts and resets.

[0010] Furthermore, the rotating base includes a base and a turntable rotatably mounted on top of the base. Two sets of clamping assemblies are fixedly mounted on top of the turntable. A rotating motor is fixedly mounted on top of the base. The output end of the rotating motor is connected to a drive gear.

[0012] Furthermore, the clamping plate includes a movable clamping plate slidably disposed with the adjustable base and a fixed clamping plate fixedly connected to the adjustable base. The adjustable base includes a base body, the inner cavity of which is provided with a threaded rod and a servo motor for driving the threaded rod to rotate. A movable block is screwed onto the threaded rod. Slide grooves are provided on both sides of the base body, and a sliding arm connected to the movable block is slidably disposed in the slide groove. The other end of the sliding arm is connected to the movable clamping plate.

[0013] Furthermore, the fixed clamp is provided with a driving unit inside, and a first toothed ring is rotatably provided in the inner cavity of the fixed clamp. The first toothed ring is coaxially and fixedly connected to the rotating support ring. The driving unit includes a first gear meshing with the first toothed ring and a drive motor for driving the first gear to rotate.

[0014] Furthermore, the flexible airbag is fitted and sealed to the outer periphery of the protrusion, the outer surface of the flexible airbag is provided with abrasive grains, and the inner cavity of the protrusion is in communication with the flexible airbag.

[0015] Furthermore, the clamping assembly also includes a three-way tube, one end of which is connected to a first flexible tube that communicates with a flexible airbag on one side of the movable clamping plate, and the other end of which is connected to a second flexible tube that communicates with a flexible airbag on one side of the fixed clamping plate.

[0016] Furthermore, the pressurizing assembly includes a hollow tube fixedly disposed at the bottom of the turntable. A first connecting pipe and a second connecting pipe are connected to the outer periphery of the hollow tube. A piston is slidably disposed inside the hollow tube. The outer periphery of the piston is in a sealing sliding fit with the inner wall of the hollow tube. A lead screw that passes downward through the bottom of the hollow tube is rotatably connected to the bottom of the piston.

[0017] Furthermore, a second gear is screwed onto the outer periphery of the lead screw, the second gear is rotatably connected to the bottom of the hollow tube, a limit pin is fixedly provided at the bottom of the lead screw, and a limit groove is provided at the top of the base to slide with the limit pin.

[0018] Furthermore, a third gear is provided between the second internal gear ring and the second gear, the third gear meshing with both the second internal gear ring and the second gear, and the gear ratio of the third gear being greater than that of the second gear.

[0019] This invention utilizes an inflatable flexible airbag, which automatically conforms to the inner wall of the pipe fitting's inner end after inflation, uniformly grinding burrs on the inner wall during pipe rotation, thereby improving the deburring effect of the pipe fitting's inner end. Simultaneously, through the coordinated operation of the rotating base, pressurizing component, and clamping component, the clamping component can synchronously complete the inflation and depressurization of the flexible airbag during station switching, eliminating the need for a separate inner wall grinding drive mechanism and reducing the overall structural complexity of the equipment. Furthermore, this invention employs a dual-station cyclic switching structure, enabling alternating workpiece grinding and loading / unloading, reducing workpiece processing intervals, improving continuous processing efficiency and automation, and demonstrating good practicality.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0036] It should be noted that, unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 As shown, this embodiment provides a burr removal device for lithium battery processing, including a rotating base 1 and two sets of clamping components 2 disposed on the top of the rotating base 1. The two sets of clamping components 2 are divided into component one and component two, and the two sets of clamping components 2 are arranged at intervals along the circumferential direction of the rotating base 1.

[0038] The rotating base 1 has a grinding station on the side closest to the grinding device 5, and a material handling station on the opposite side. In use, the operator can install the pipe to be processed 4 onto the corresponding clamping assembly 2 at the material handling station. After the rotating base 1 rotates, the pipe to be processed 4 can be transported to the grinding station for deburring. At the same time, the processed pipe 4 is moved to the material handling station for removal, thereby realizing the cyclic switching of loading, processing and unloading, and improving the overall processing efficiency.

[0039] Specifically, the rotating base 1 includes a base 11 fixedly mounted on the ground and a turntable 12 rotatably mounted on the top surface of the base 11, with two sets of clamping assemblies 2 fixedly mounted on the top surface of the turntable 12. The base 11 is internally provided with a drive structure for driving the turntable 12 to rotate.

[0040] Preferably, the drive structure includes a rotary motor 111 fixedly mounted on the top of the base 11, a drive gear 112 fixedly connected to the output end of the rotary motor 111, and a second internal gear ring 38 fixedly mounted on the bottom of the turntable 12. The drive gear 112 and the second internal gear ring 38 mesh with each other. In use, the rotary motor 111 is started to drive the drive gear 112 to rotate, and the drive gear 112 drives the second internal gear ring 38 to rotate, thereby realizing the rotation of the turntable 12.

[0041] Furthermore, a rotating ring 113 is rotatably mounted on the top of the base 11. Multiple sets of columns 114 are fixedly mounted on the top of the rotating ring 113. The top of the multiple sets of columns 114 is fixedly connected to the bottom of the second internal toothed ring 38 to support the turntable 12, thereby improving the stability of the turntable 12 during rotation.

[0042] In order to protect the structure located at the bottom of the turntable 12, a protective ring plate 121 is fixedly installed at the bottom of the turntable 12. The protective ring plate 121 is located outside the pressure assembly 3, and the second internal toothed ring 38 is fixedly installed at the bottom of the protective ring plate 121.

[0043] like Figure 9 and Figure 10 As shown, the clamping assembly 2 includes an adjustable base 21 fixedly mounted on the top of the turntable 12. Two sets of clamping plates 22 are provided at both ends of the top surface of the adjustable base 21. The two sets of clamping plates 22 are used to clamp and position the two ends of the pipe fitting 4.

[0044] The clamping plate 22 includes a movable clamping plate 221 that is slidably disposed with the adjustable base 21 and a fixed clamping plate 222 that is fixedly connected to the adjustable base 21. The adjustable base 21 can drive the movable clamping plate 221 to move along the length direction of the adjustable base 21 to adapt to the clamping requirements of pipe fittings 4 of different lengths.

[0045] The adjustable base 21 includes a base body 211. A servo motor 213 is provided at one end of the inner cavity of the base body 211. The output end of the servo motor 213 is connected to a threaded rod 212. The other end of the threaded rod 212 is rotatably connected to the other end of the inner cavity of the base body 211. A moving block 214 is screwed onto the threaded rod 212. Slide grooves 215 are provided on both sides of the base body 211. Slide arms 216 slide in the slide grooves 215 respectively. One end of the slide arm 216 is connected to the moving block 214, and the other end is connected to the moving clamp 221.

[0046] Rotating support rings 25 are rotatably provided on the side of each of the two sets of clamping plates 22 that are relatively close to the pipe fitting 4. The two rotating support rings 25 are coaxially arranged and correspond to the two ends of the pipe fitting 4 respectively, so as to support the pipe fitting 4 and drive the pipe fitting 4 to rotate synchronously.

[0047] Furthermore, a drive unit 26 is provided inside the fixed clamping plate 222, which is used to drive the rotating support ring 25 to rotate.

[0048] Specifically, a first gear ring 251 is rotatably disposed on the side of the inner cavity of the fixed clamping plate 222 near the rotating support ring 25, and the first gear ring 251 is coaxially and fixedly connected to the rotating support ring 25. The driving unit 26 includes a first gear 261 rotatably disposed on the inner side of the fixed clamping plate 222, the first gear 261 meshing with the first gear ring 251, and a drive motor 262 is fixedly disposed on the outer side of the fixed clamping plate 222, the output end of the drive motor 262 being connected to the first gear 261.

[0049] In use, the drive motor 262 drives the first gear 261 to rotate, the first gear 261 drives the first gear ring 251 to rotate, and the first gear ring 251 drives the rotating support ring 25 to rotate synchronously, thereby driving the pipe 4 clamped between the two sets of rotating support rings 25 to rotate synchronously to meet the subsequent grinding requirements.

[0050] Furthermore, a protrusion 23 is fixedly provided on one side of the two sets of clamping plates 22 near the pipe fitting 4, and the protrusion 23 is located at the center of the rotating support ring 25. The protrusion 23 can be inserted into the port of the pipe fitting 4.

[0051] A flexible airbag 24 is provided on the outer periphery of the protrusion 23. The flexible airbag 24 is sleeved and sealed to the outer periphery of the protrusion 23. The flexible airbag 24 is preferably made of a flexible sealing material with elastic deformation capability. Abrasive grains are fixedly provided on the outer surface of the flexible airbag 24. The abrasive grains can be one of diamond, silicon carbide or alumina abrasive grains, for grinding and deburring the inner end of the pipe fitting 4.

[0052] Furthermore, the clamping assembly 2 also includes a three-way pipe 39, with two sets of three-way pipes 39 respectively disposed on the top of the rotating base 1 and corresponding to the two sets of clamping assemblies 2. The three-way pipes 39 are used to connect the flexible airbags 24 at both ends of the corresponding clamping assembly 2 to achieve synchronous gas delivery.

[0053] Specifically, one end of the three-way pipe 39 is connected to a first flexible hose 391, which is connected to a flexible airbag 24 on one side of the movable clamping plate 221; the other end of the three-way pipe 39 is connected to a second flexible hose 392, which is connected to a flexible airbag 24 on one side of the fixed clamping plate 222. Through this structural arrangement, the gas output from the pressurizing component 3 can be simultaneously delivered through the three-way pipe 39 to the flexible airbags 24 at both ends of the same set of clamping components 2, thereby causing the flexible airbags 24 on both sides to expand synchronously and fit against the inner walls of both ends of the pipe fitting 4, ensuring that the inner walls of both ends of the pipe fitting 4 can be simultaneously ground and deburred.

[0054] Furthermore, the inner cavity of the protrusion 23 is connected to the three-way pipe 39, and a through hole 231 is provided on the outer periphery of the protrusion 23, which is connected to the inner cavity of the flexible airbag 24.

[0055] In use, after the gas enters the protrusion 23 through the three-way pipe 39, the gas enters the flexible airbag 24 through the through hole 231, causing the flexible airbag 24 to expand and fit against the inner wall of the tube 4. As the tube 4 rotates, the abrasive particles on the outer surface of the flexible airbag 24 can uniformly polish the inner wall of the tube 4 port, thereby removing burrs from the port.

[0056] like Figures 6 to 8 As shown, the bottom of the turntable 12 is provided with a pressurization component 3 for inflating and depressurizing the flexible airbag 24.

[0057] Specifically, the pressurizing component 3 includes a hollow tube 31 fixedly mounted at the bottom of the turntable 12. A first connecting pipe 32 is connected to the top of the outer periphery of the hollow tube 31, and a second connecting pipe 33 is connected to the bottom of the outer periphery of the hollow tube 31. The first connecting pipe 32 and the second connecting pipe 33 are located on the upper and lower sides of the axial movement path of the piston 34, respectively, and the piston 34 is located between the first connecting pipe 32 and the second connecting pipe 33. When the piston 34 moves, it can change the air pressure in the corresponding cavities of the first connecting pipe 32 and the second connecting pipe 33 to form gas compression and suction states, respectively. The first connecting pipe 32 is connected to the three-way pipe 39 corresponding to component one, and the second connecting pipe 33 is connected to the three-way pipe 39 corresponding to component two.

[0058] A piston 34 is slidably disposed inside the hollow tube 31, and the piston 34 can move along the axial direction of the hollow tube 31. A lead screw 35 is rotatably connected to the bottom of the piston 34, and the lead screw 35 passes downward through the bottom of the hollow tube 31. The bottom of the hollow tube 31 is provided with a sealing structure to ensure the airtightness of the interior of the hollow tube 31.

[0059] A second gear 36 is threaded onto the outer circumference of the lead screw 35. The second gear 36 is screwed into the lead screw 35 and is rotatably connected to the bottom of the hollow tube 31. A limit pin 351 is fixedly provided at the bottom of the lead screw 35, and the limit pin 351 is preferably square in structure.

[0060] Correspondingly, a limiting groove 352 is provided at the top center of the base 11, and a limiting pin 351 is slidably disposed inside the limiting groove 352, and the limiting groove 352 can restrict the rotation of the limiting pin 351.

[0061] Therefore, when the second gear 36 rotates, the screw 35 is restricted from rotating due to the cooperation between the limiting pin 351 and the limiting groove 352. The second gear 36 can drive the screw 35 to move in the axial direction, and the screw 35 further drives the piston 34 to move inside the hollow tube 31, thereby realizing the compression and suction of the gas inside the hollow tube 31.

[0062] Furthermore, in order to increase the travel of the piston 34 and the inflation / deflation of the flexible airbag 24, a third gear 37 is provided between the second internal gear ring 38 and the second gear 36.

[0063] Specifically, the third gear 37 is rotatably mounted on the top of the base 11 via a rotating shaft. The third gear 37 meshes with both the second internal gear ring 38 and the second gear 36, and the gear ratio of the third gear 37 is greater than that of the second gear 36.

[0064] In use, when the turntable 12 rotates, the second internal gear ring 38 drives the third gear 37 to rotate, and the third gear 37 further drives the second gear 36 to rotate. Since there is a gear ratio difference between the third gear 37 and the second gear 36, the rotation stroke of the second gear 36 can be amplified, thereby increasing the moving distance of the piston 34 driven by the lead screw 35 to meet the gas inflation and deflation requirements of the flexible airbag 24.

[0065] The working process of this embodiment is as follows:

[0066] In the initial state, component one is located at the material handling station, and component two is located at the grinding station. The operator first installs the pipe fitting 4 to be processed onto component one located at the material handling station, and adjusts the position of the moving clamp 221 to stably clamp the pipe fitting 4 between the two sets of rotating support rings 25.

[0067] Subsequently, the rotating motor 111 is started. The rotating motor 111 drives the second internal gear ring 38 to rotate through the drive gear 112, thereby driving the turntable 12 to rotate 90 degrees clockwise.

[0068] During the rotation of turntable 12, hollow tube 31 rotates synchronously. Second internal gear ring 38 drives second gear 36 to rotate through third gear 37. Second gear 36 drives lead screw 35 to move upward, thereby driving piston 34 to move upward.

[0069] When the piston 34 moves upward, the gas inside the hollow tube 31 is compressed and enters the flexible airbag 24 on the corresponding component through the first connecting tube 32, the three-way tube 39, the protrusion 23 and the through hole 231, causing the flexible airbag 24 to expand and fit tightly against the inner wall of the tube 4.

[0070] At the same time, the gas inside the flexible airbag 24 of component 2, which moves from the grinding station to the material handling station, flows back to the hollow tube 31 through the second connecting pipe 33, thereby causing the flexible airbag 24 to contract, reset, and detach from the inner wall of the tube 4.

[0071] After the turntable 12 completes a 90-degree rotation, the component located at the grinding station begins grinding. At this time, the drive motor 262 operates, driving the tube 4 to rotate around its own axis. Simultaneously, the grinding device 5 grinds the outer end of the tube 4, while the flexible airbag 24 grinds the inner end of the tube 4, thereby achieving simultaneous removal of burrs from both the inner and outer ends of the tube 4.

[0072] After the current pipe fitting 4 has been polished, the worker removes the finished pipe fitting 4 and installs the new pipe fitting 4 to be processed into component two at the material handling station. Subsequently, the rotating base 1 rotates 90 degrees in the opposite direction, and the piston 34 moves in the opposite direction, thereby realizing the inflation of another set of flexible airbags 24 and the depressurization and reset of the current flexible airbag 24, thus achieving continuous automated removal of burrs at the inner end of the pipe fitting 4 in this cycle.

[0073] This embodiment incorporates an inflatable flexible airbag 24, which, after inflation, automatically conforms to the inner wall of the inner port of the pipe fitting 4 of different sizes. This, combined with the rotation of the pipe fitting 4, achieves uniform grinding, improving the removal of burrs from the inner port and reducing the risk of damage to the inner wall of the pipe fitting 4 caused by traditional rigid grinding structures. Furthermore, the coordinated operation between the turntable 12 and the pressurizing component 3 enables the automatic inflation and deflation of the flexible airbag 24 during station switching, allowing for automatic positioning and resetting without the need for an additional independent control system.

[0074] Specifically, the grinding device 5 includes an electric slide rail 51 fixedly installed on the ground, a support column 52 slidably installed on the top of the electric slide rail 51, a top plate 53 fixedly installed on the top of the support column 52, and a limit seat 531 installed on the top of the top plate 53.

[0075] An electric telescopic rod 54 is provided on the top of the top plate 53. A grinding motor 55 is fixedly installed at the output end of the electric telescopic rod 54. A grinding disc 56 is connected to the output end of the grinding motor 55.

[0076] In use, the electric slide rail 51 can adjust the movement position of the grinding disc 56 in the front-to-back direction, the electric telescopic rod 54 can adjust the movement position of the grinding disc 56 in the left-to-right direction, and the grinding motor 55 drives the grinding disc 56 to rotate at high speed, thereby meeting the grinding requirements of the pipe fittings 4 ports at different positions.
