Description

Technical Field

[0001] The embodiments of the present invention relate to the field of polishing apparatus technology, and more specifically, to a polishing apparatus for processing automotive battery pressure plates. Background Technology

[0002] In the automotive manufacturing industry, battery plates play a crucial role in securing batteries, preventing vibration and displacement, and providing insulation protection. Their surface quality directly affects the battery's lifespan and vehicle safety performance. During the processing of the plates, metal burrs, flash, or oxide layers may remain on the surface. These defects can lead to surface conductivity and cause short circuits in the battery. Polishing with polishing equipment can completely remove surface impurities, significantly improve insulation performance, and prevent abnormal current conduction.

[0003] In existing technologies, conventional polishing equipment can polish the surface of the pressure plate using an upper polishing wheel, but it is difficult to fully grind burrs, flash, and oxide layers at the corners of the upper and lower edges of the pressure plate. Since existing equipment cannot cover the polishing needs of corner areas, operators often need to manually process the unpolished areas later. This not only leads to low polishing efficiency but also significantly increases manual operation time and production costs. To address this, we propose a polishing device for processing automotive battery pressure plates. Summary of the Invention

[0004] To overcome the above-mentioned defects, the present invention provides a polishing device for processing automotive battery pressure plates, which solves the problem that conventional polishing equipment in the prior art is unable to fully polish the burrs, flash and oxide layer at the corners of the upper and lower edges of the pressure plate. Since the existing equipment cannot cover the polishing needs of the corner areas, operators often need to manually process the unpolished parts later, which not only leads to low polishing efficiency, but also greatly increases the manual operation time and production costs.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a polishing device for processing automotive battery pressure plates, comprising a frame, an upper polishing wheel, a worktable, and a pressure plate body; wherein an auxiliary polishing mechanism is provided on the frame, the auxiliary polishing mechanism comprising: The tripod and polishing belt are provided. Rotating belts are fixedly installed on both sides of the polishing belt. One side of the tripod is respectively equipped with a first I-shaped wheel, two sets of pressure wheels and two sets of second I-shaped wheels, which are used to drive the rotating belt and polishing belt to rotate. A horizontal lead screw is rotatably mounted on the top of the frame, and a nut block is mounted on the outside of the horizontal lead screw.

[0006] Preferably, a speed reduction motor is provided at one end of the horizontal lead screw, a slider is fixedly provided on the back of the tripod, and a slide rail is fixedly provided on the inner wall of the frame.

[0007] Preferably, a crossbeam is fixedly installed on the frame, and a motor is fixedly installed inside the crossbeam. The pressure wheel contacts the outer wall of the rotating belt and the polishing belt, and the first I-shaped wheel and two sets of second I-shaped wheels contact the inner wall of the rotating belt.

[0008] Preferably, a protruding plate is fixedly provided on the top of the second nut block, and a T-shaped screw is threadedly connected to the inside of the protruding plate.

[0009] Preferably, an adjusting component is provided between the pressure wheel and the tripod. The adjusting component includes a concave frame fixed to the front of the tripod and two sets of fixed frames. A two-way lead screw is rotatably provided inside the concave frame, and an upper motor is fixedly provided on the top of the concave frame. The external part of the bidirectional lead screw is provided with two sets of nut blocks.

[0010] Preferably, a mounting plate is fixedly installed on the concave frame, and a T-shaped screw is threadedly connected to the inside of the mounting plate.

[0011] Preferably, the tripod is provided with a clamping member for clamping the rotating belt and the polishing belt, the clamping member comprising: The upper plate is fixed to the tripod, and a stud is provided inside the upper plate. A threaded ring is connected to the outside of the stud by a thread. A stop wheel is rotatably provided on the stud.

[0012] Preferably, the tripod is provided with an arc edge polishing assembly, which includes two sets of horizontal spiral plates and two sets of movable frames that are slidably disposed inside the horizontal spiral plates. A connecting motor is fixedly disposed on the top of the movable frame, and a rotating rod is rotatably disposed inside the movable frame. A lower polishing wheel is fixedly disposed outside the rotating rod for polishing the arc edges at the corners of the pressure plate body. A connecting spring is fixedly installed between the horizontal spiral plate and the movable frame.

[0013] Preferably, a lifting component is provided between the two sets of horizontal spiral plates. The lifting component includes two sets of vertical spiral plates and a lifting frame that is slidably disposed inside the vertical spiral plates. The interior of the vertical spiral plates is connected by a locking screw. The interior of the horizontal spiral plate is connected by a locking screw via a thread.

[0014] Preferably, a gantry frame is fixedly mounted on the frame, a transverse plate is slidably mounted on the gantry frame, a hydraulic cylinder is fixedly mounted on the transverse plate, and a drive motor is fixedly mounted on the bottom working end of the hydraulic cylinder.

[0015] The beneficial effects of the embodiments of the present invention are as follows: (1) The present invention combines an auxiliary polishing mechanism and an adjusting component. The first and second I-shaped wheels make the polishing sand belt form a V-shaped structure. The included angle of the inner side can directly contact the edge corners of the upper and lower surfaces of the pressure plate body to polish the edge corners of the upper and lower surfaces of the pressure plate body. The adjusting component drives the two sets of pressing wheels to move through the bidirectional screw, changing the opening angle of the V-shaped sand belt. This allows the contact angle and contact pressure between the inner wall of the polishing sand belt and the upper and lower edge corners of the pressure plate body to be adapted and matched to pressure plate bodies of different thicknesses, ensuring that burrs, flash and oxide layer are thoroughly polished.

[0016] (2) The present invention, through the design of the clamping component, can ensure that the polishing sand belt and the rotating belt are in a taut state during use after adjusting the distance between the two sets of pressure wheels. At the same time, with the long-term use of the polishing device, the polishing sand belt and the rotating belt may become loose due to wear and other reasons. At this time, the tightness can be adjusted by the clamping component to bring the polishing sand belt and the rotating belt back to a taut state. There is no need to frequently replace parts, which reduces maintenance costs and workload, while ensuring the continuous and efficient operation of the polishing device.

[0017] (3) By combining the designed arc-edge polishing component and the lifting component, the present invention can simultaneously polish the arc-shaped surface and the surrounding surface of the pressure plate body with different thicknesses, thereby improving the polishing efficiency of the pressure plate body. The moving frame can slide in the horizontal loop plate, so that the lower polishing wheel can automatically adjust its position according to the arc-shaped edge of the pressure plate body. When the auxiliary polishing mechanism moves, the lower polishing wheel will compress or stretch the spring due to the pressure of the arc-shaped surface, and always keep in contact with the arc-shaped surface, avoiding polishing omissions due to changes in the arc-shaped edge curvature. Moreover, through the sliding cooperation between the vertical loop plate and the lifting frame, the position of the horizontal loop plate can be adjusted up and down, thereby changing the vertical distance between the two sets of lower polishing wheels, so that the polishing wheel can polish the arc-shaped surface and the surrounding surface of the pressure plate body with different thicknesses, thereby improving applicability.

[0026] Example 1 Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10This invention provides a technical solution: a polishing device for processing automotive battery pressure plates, comprising a frame 100, an upper polishing wheel 104, a worktable 108, and a pressure plate body 105 disposed on the top of the worktable 108. An auxiliary polishing mechanism is provided on the frame 100, the auxiliary polishing mechanism including: The tripod 200 and the polishing belt 201 are thicker than the rotating belt 204. At this time, the polishing belt 201 is in contact with the surface of the pressure plate body 105, while the rotating belt 204 is not in contact with the pressure plate body 105. The rotating belt 204 is fixedly installed on both sides of the polishing belt 201. The tripod 200 is rotatably equipped with a first I-shaped wheel 209, two sets of pressing wheels 213 and two sets of second I-shaped wheels 214 on one side, which are used to drive the rotating belt 204 and the polishing belt 201 to rotate. An active motor 217 is fixedly installed inside the tripod 200. The active motor 217 drives the first I-shaped wheel 209 to rotate, and the working end of the active motor 217 is fixedly connected to the first I-shaped wheel 209. A horizontal lead screw 203 is rotatably mounted on the top of the frame 100. A second nut block 211 is mounted on the outside of the horizontal lead screw 203. When the second nut block 211 moves on the horizontal lead screw 203, it drives the tripod 200 to move accordingly. An L-shaped plate 207 is fixedly mounted between the second nut block 211 and the tripod 200. A reduction motor 202 is installed at one end of the horizontal lead screw 203. Two sets of vertical plates are fixedly installed on the top of the frame 100. Both ends of the horizontal lead screw 203 are rotatably installed inside the vertical plates. The reduction motor 202 is fixed on the vertical plates. A slider 205 is fixedly installed on the back of the tripod 200. A slide rail is fixedly installed on the inner wall of the frame 100. When the tripod 200 moves, it will also drive the slider 205 to slide on the slide rail, which can increase the stability of the tripod 200 when it moves. The slider 205 can slide on the slide rail. A crossbeam 101 is fixedly mounted on the frame 100. A motor 206 is fixedly mounted inside the crossbeam 101, and the working end of the motor 206 is fixedly connected to the bottom of the worktable 108. An air slip ring is installed on the outside of the worktable 108, and the air slip ring is connected to an external negative pressure pump to provide negative pressure to the negative pressure holes on the worktable 108. The air slip ring consists of a rotating ring and a stationary ring. The rotating ring is connected to the worktable 108, and the stationary ring is connected to the external negative pressure pump via a connecting pipe. The top of the worktable 108 has multiple sets of negative pressure holes, and the interior of the worktable 108 has a connecting cavity that is connected to the negative pressure holes. The pressure wheel 213 contacts the outer wall of the rotating belt 204 and the polishing sand belt 201. The first I-shaped wheel 209 and the two sets of second I-shaped wheels 214 contact the inner wall of the rotating belt 204. When polishing the corners of the edges of the pressure plate body 105 of different lengths and widths, the pressure plate body 105 on the worktable 108 can be picked up and adjusted as needed to facilitate polishing. A protruding plate 501 is fixedly installed on the top of the nut block 211. A T-shaped screw 500 is threadedly connected inside the protruding plate 501. When the upper polishing wheel 104 polishes the pressure plate body 105, the T-shaped screw 500 can clamp and limit the horizontal lead screw 203 to prevent the reduction motor 202 from starting unexpectedly and causing the horizontal lead screw 203 to rotate, which would cause the tripod 200 to move and affect the polishing of the upper polishing wheel 104. The bottom of the T-shaped screw 500 extends to the surface of the horizontal lead screw 203.

[0027] Example 2 Please refer to Example 1. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 An adjusting component is provided between the clamping roller 213 and the tripod 200 to adjust the distance between the two sets of clamping rollers 213. The adjusting component includes a concave frame 216 fixed on the front of the tripod 200 and two sets of fixed frames 215. A bidirectional lead screw 212 is rotatably provided inside the concave frame 216. An upper motor 208 is fixedly provided on the top of the concave frame 216, and the working end of the upper motor 208 is fixedly connected to the top of the bidirectional lead screw 212. Two sets of nut blocks 210 are provided on the outside of the bidirectional lead screw 212. The end of the fixing frame 215 is fixedly connected to the nut blocks 210. The pressure wheel 213 is rotatably mounted on the fixing frame 215. A mounting plate is fixedly installed on the concave frame 216. The interior of the mounting plate is connected to a T-shaped screw 502 via threads. When the upper polishing wheel 104 is polishing, the T-shaped screw 502 can clamp and limit the bidirectional lead screw 212 to prevent the upper motor 208 from rotating unexpectedly, causing the bidirectional lead screw 212 to rotate and the positions of the two sets of pressure wheels 213 to change, which would affect the subsequent polishing of the pressure plate body 105 by the polishing sand belt 201. The working end of the T-shaped screw 502 extends to the surface of the bidirectional lead screw 212.

[0028] In summary, the air slip ring is connected to an external negative pressure pump. At this time, multiple sets of negative pressure holes on the worktable 108 generate negative pressure, placing the pressure plate body 105 at a suitable position on the worktable 108. The negative pressure generated by the negative pressure holes firmly adheres and fixes the pressure plate body 105. The drive motor 103 is then turned on, and its working end rotates, driving the upper polishing wheel 104 to rotate at high speed. Then, the hydraulic cylinder 102 is activated, and its working end moves downwards, driving the drive motor 103 to move. The drive motor 103 then drives the upper polishing wheel 104 to descend and contact the… The upper surface of the pressure plate body 105 is polished. Then, as the transverse plate moves left and right on the gantry 107 and the gantry 107 moves back and forth on the sliding rail, the upper polishing wheel 104 moves back and forth and left and right to polish the upper surface of the pressure plate body 105. After polishing, the negative pressure pump is turned off. Then, the pressure plate body 105 is picked up, rotated 180 degrees and placed in a suitable position on the worktable 108. Then, the negative pressure pump is turned on to adsorb and fix the pressure plate body 105. At this time, the area at the bottom of the pressure plate body 105 that was not polished is polished. After polishing is complete, the active motor 217 is turned on, driving the first I-shaped wheel 209 to rotate. The rotation of the first I-shaped wheel 209 drives the two sets of external transmission belts 204 to rotate at high speed. The two sets of transmission belts 204 drive the polishing sand belt 201 to rotate at high speed. At this time, the transmission belts 204 drive the second I-shaped wheel 214 and the pressure wheel 213 to rotate as well. Then, the reduction motor 202 is turned on, driving the horizontal lead screw 203 to rotate. At this time, the second nut block 211 located outside the horizontal lead screw 203 moves to the right, causing the L-shaped plate 207, the tripod 200, the transmission belt 204, the polishing sand belt 201 and other structures to move to the right as well. Then, the inner wall of the polishing sand belt 201 begins to contact the upper and lower surface edges and corners of the front of the pressure plate body 105 for polishing, removing burrs, flash and oxidation. After thorough grinding and polishing, the upper and lower edge corners of the front surface of the pressure plate body 105 are polished after moving to the right until they are separated from and in contact with the rightmost position. After polishing, the tripod 200 stops moving and the reduction motor 202 is turned off. Then the installation motor 206 is started, and the working end drives the worktable 108 to rotate 90 degrees, causing the pressure plate body 105 to rotate 90 degrees as well. Then the working end of the reduction motor 202 is reversed, and the nut block 211 moves to the left, causing the tripod 200, polishing sand belt 201 and other structures to move to the left. Then the unpolished upper and lower edge corners of the front surface of the pressure plate body 105 can be polished. This process is repeated to thoroughly grind the burrs, flash and oxide layer at the upper and lower four edges of the pressure plate body 105. The polishing belt 201 has a V-shaped structure in its side view. The inner angle of the V-shape contacts the front of the pressure plate body 105, specifically at the corners of the upper and lower surfaces, thus polishing the corners. During use, the inner angle of the V-shape of the polishing belt 201 can be adjusted according to the thickness of the pressure plate body 105. During adjustment, the upper motor 208 is turned on, and its working end drives the bidirectional lead screw 212 to rotate. This causes the two sets of nut blocks 210 on the bidirectional lead screw 212 to move in opposite directions. (When the pressure plate body 105 is thicker, the two sets of nut blocks 210 move in opposite directions. At this time, the two sets of clamping wheels 213 move in opposite directions, increasing the number of nut blocks 210.) The spacing between them (the opposite is true when the thickness of the pressure plate body 105 is not too thick) nut block 210 drives the corresponding clamping wheel 213 to move in opposite or opposite directions, thereby loosening or tightening the polishing belt 201. At this time, the spacing between the polishing belts 201 between the two sets of clamping wheels 213 increases or decreases, so that the inner included angle of the V-shaped polishing belt 201 contacts the corners at the edges of the upper and lower surfaces of the pressure plate body 105 for polishing. At the same time, according to the same operation method, the inner included angle of the V-shaped polishing belt 201 can be adjusted according to actual needs, so that the inner wall of the polishing belt 201 contacts the corners at the edges of the upper and lower surfaces of the pressure plate body 105 at different angles, thereby increasing the polishing effect.

[0029] Example 3 Please refer to Example 2. Figure 1 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figure 10 and Figure 11 The tripod 200 is provided with a clamping member for clamping the rotating belt 204 and the polishing sand belt 201. The clamping member includes an upper plate 301 fixed on the tripod 200. A stud 302 is provided inside the upper plate 301. A threaded ring 303 is threadedly connected to the outside of the stud 302. A stop wheel 300 is rotatably provided on the stud 302. The stop wheel 300 and the stud 302 are rotatably connected by a rotating shaft.

[0030] In summary, before the spacing of the two sets of clamping rollers 213 is adjusted, the threaded ring 303 is loosened by rotating it away from the upper plate 301. Then, the stud 302 is moved away from the polishing belt 201. This will cause the stud 302 to slide inside the upper plate 301, causing the abutment roller 300 to move and disengage from the surfaces of the polishing belt 201 and the rotating belt 204. After the spacing of the two sets of clamping rollers 213 is adjusted, the abutment roller 300 is moved closer to the polishing belt 201, causing the abutment roller 300 to move along with it. Then, the abutment roller 300 contacts and presses against the polishing belt 201 and the two sets of rotating belts 204, keeping the polishing belt 201 and the two sets of rotating belts 204 in a taut state. This prevents the polishing belt 201 and the two sets of rotating belts 204 from becoming loose when the spacing of the two sets of clamping rollers 213 is adjusted. Finally, the threaded ring 303 is tightened by rotating it closer to the upper plate 301 to fix the stud 302. At the same time, the tension of the transmission belt 204 and the polishing belt 201 can also be adjusted by using the abutment wheel 300 to tighten them, so that the polishing belt 201 and the two sets of rotating belts 204 are always taut during use, thus preventing them from loosening after a long period of use.

[0031] Example 4 Please refer to Example 3. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 12 , Figure 13 and Figure 14 The tripod 200 is equipped with an arc edge polishing assembly, which includes two sets of horizontal spiral plates 405 and two sets of movable frames 402 that are slidably disposed inside the horizontal spiral plates 405. A connecting motor 401 is fixedly disposed on the top of the movable frame 402, and the bottom working end of the connecting motor 401 is fixedly connected to the top of the rotating rod. A rotating rod is rotatably disposed inside the movable frame 402, and a lower polishing wheel 400 is fixedly disposed outside the rotating rod for polishing the arc edges at the corners of the pressure plate body 105. A connecting spring 403 is fixedly disposed between the horizontal spiral plates 405 and the movable frame 402. A lifting component is provided between the two sets of horizontal spiral plates 405 to adjust the thickness of the arc edge at the corner of the pressure plate body 105 (that is, to adjust the vertical distance between the two sets of lower polishing wheels 400). The lifting component includes two sets of vertical spiral plates 408 and a lifting frame 404 slidably disposed inside the vertical spiral plates 408. The interior of the vertical spiral plates 408 is connected by a locking screw 409 through a thread, and the working end of the locking screw 409 extends to the surface of the lifting frame 404. A connecting plate 406 is fixedly provided between the horizontal spiral plates 405 and the tripod 200. The interior of the horizontal spiral plate 405 is connected by a locking screw 407 via threads, and the top of the locking screw 407 extends to the surface of the movable frame 402. When polishing the arc-shaped surface around the pressure plate body 105, the top of the locking screw 407 is not disengaged from the movable frame 402, and the movable frame 402 can move within the horizontal spiral plate 405. When polishing the right-angled corners around the pressure plate body 105, the movable frame 402 can be fixed to prevent the lower polishing wheel 400 from contacting the pressure plate body 105. The movable frame 402 is moved away from the lower polishing wheel 400, causing the lower polishing wheel 400 to move along with it. Then, the locking screw 407 is rotated upwards and tightened so that the top of the locking screw 407 contacts and locks the movable frame 402. At this time, the lower polishing wheel 400 is limited and fixed, and when it moves with the tripod 200, the lower polishing wheel 400 will not contact the outer surface of the pressure plate body 105.

[0032] In summary, the curved edges at the corners of some pressure plate bodies 105 can also be polished. During polishing, before the tripod 200 begins to move, two sets of connecting motors 401 are activated. The working ends of the two sets of connecting motors 401 rotate, causing the rotating rod to rotate, which in turn drives the corresponding lower polishing wheel 400 to rotate at high speed. Then, as the tripod 200 begins to move, it drives the polishing belt 201 to polish, simultaneously moving the lower polishing wheel 400 to contact the left side surface of the pressure plate body 105. As it moves, it contacts the curved surface at the left corner, and polishing begins on the curved surface at the left corner. As it moves to the right, the two sets of lower polishing wheels 400 are squeezed by the curved surface, and the moving frame 402 moves away from the lower polishing wheels. When the moving frame 402 slides inside the horizontal plate 405, the connecting spring 403 is pulled by the moving frame 402 away from the lower polishing wheel 400. The lower polishing wheel 400 can be adjusted in position according to the curvature of the corner arc surface of the pressure plate body 105 and always keep in contact with the arc surface. During this period, the rotating lower polishing wheel 400 polishes the arc surface. As the tripod 200 moves to the right, after the lower polishing wheel 400 finishes polishing the arc edge, it begins to contact the front of the pressure plate body 105 and polishes the front. When it moves to the right to the right side of the pressure plate body 105 and close to the arc surface of the front, it begins to polish the arc surface of the right front of the pressure plate body 105. After polishing is completed, the lower polishing wheel 400 moves to the rightmost position of the equipment and no longer contacts the pressure plate body 105. Then, the mounting motor 206 is turned on, and the working end of the mounting motor 206 drives the worktable 108 to rotate 90 degrees, thereby causing the pressure plate body 105 to rotate 90 degrees. At this time, as the tripod 200 moves to the left, the lower polishing wheel 400 continues to polish the arc-shaped surface at the front corner of the pressure plate body 105. This process is repeated, polishing the arc-shaped surface at the corner of the pressure plate body 105 and the surrounding surface at the same time while polishing the corners of the four edges of the pressure plate body 105. No secondary polishing operation is required afterward, saving manpower and increasing polishing efficiency. Furthermore, when the thickness of the pressure plate body 105 is different, the vertical distance between the two sets of lower polishing wheels 400 can be adjusted. This allows for polishing of curved surfaces and the surrounding surfaces of the pressure plate body 105 of different thicknesses according to the different thicknesses of the pressure plate body 105. During adjustment, the locking screw 409 is loosened in the upward direction (the working end of the locking screw 409 does not contact the surface of the lifting frame 404). Then, the lifting frame 404 is moved upward, causing the horizontal spiral plate 405, the moving frame 402, and the lower polishing wheels 400 located on the left side of the lifting frame 404 to move along with it. After the movement is complete, the locking screw 409 is rotated towards the lifting frame 404 to tighten and fix the lifting frame 404 (the working end of the locking screw 409 contacts the surface of the lifting frame 404). At this time, the vertical distance between the two sets of lower polishing wheels 400 increases, which can satisfy the polishing of the surrounding surfaces and curved surfaces of the pressure plate body 105 of different thicknesses.
