Description

Technical Field

[0001] The present invention relates to the technical field of automotive gaskets, and particularly to a gasket grinding device for automotive parts and its usage method. Background Art

[0002] The gasket grinding device for automotive parts is a device specifically used for precision machining of the gasket surface, aiming to improve its flatness, smoothness, and dimensional accuracy to meet functional requirements such as sealing, shock absorption, or assembly clearance adjustment.

[0003] Existing grinding devices have significant defects in both "improving processing quality" and "optimizing production efficiency": In terms of processing quality, in the traditional direct grinding process, due to the lack of transitional treatment, the gaskets after blanking often enter the grinding station directly with burrs and metal chips, which easily leads to grinding wheel clogging or surface scratching, and the disorderly entry of gaskets easily causes positioning deviation, resulting in uneven grinding; at the same time, the instantaneous stress after blanking is not fully released, and direct grinding easily exacerbates the risk of thermal deformation, affecting dimensional accuracy. In terms of production efficiency, the strong coupling between the blanking and grinding devices makes it difficult to match the production rhythm. The imbalance in production capacity between high-speed blanking and low-speed grinding easily causes material accumulation or feeding interruption, and the vibration transmission between devices accelerates the wear of precision components. Frequent maintenance further reduces the operating rate, and continuous flexible production cannot be achieved, resulting in limited overall efficiency.

[0004] Therefore, the present application provides a gasket grinding device for automotive parts and its usage method to solve the problems raised in the above background art. Summary of the Invention

[0005] The purpose of the present invention is to provide a gasket grinding device for automotive parts and its usage method, which solves the problems that existing grinding devices cannot improve processing quality by reducing burr interference and stabilizing gasket positioning, and cannot balance the time rhythm difference between blanking and grinding, resulting in low production efficiency.

[0006] To solve the above technical problems, the present invention provides a gasket grinding device for automotive parts, including a first conveyor belt. The first conveyor belt includes a horizontal conveyor surface and an inclined conveyor surface connected in sequence along the conveying direction. A horizontal second conveyor belt is arranged below the conveying end of the inclined conveyor surface, and a grinding assembly is arranged at the conveying end of the second conveyor belt;

[0007] The first conveyor belt is controlled by a vibration conveyor motor. The first conveyor belt includes a plurality of conveyor chain plates. On the front and rear sides of each conveyor chain plate along the conveying direction, an upwardly warped edge and a downward pressing edge are respectively arranged. The angle between the upwardly warped edge and the conveyor chain plate is 120° to 150°. The upwardly warped edge and the downward pressing edge are in opposite directions. The gap between adjacent conveyor chain plates is 1.1 times the thickness of the gasket, and the outer diameter of the gasket is smaller than the total width of adjacent two conveyor chain plates.

[0008] A further improvement of the technical solution of the present invention lies in that: the grinding assembly includes support columns arranged on both sides of the second conveyor belt. A horizontal mounting plate is commonly provided at the tops of the support columns. A lifting motor is provided at the top of the mounting plate. The output shaft of the lifting motor penetrates through the mounting plate and is vertically connected to a lifting rod downward. A horizontal lifting plate is fixedly provided at the end of the lifting rod. Two rotating motors are provided at the top of the lifting plate. The output shafts of the rotating motors penetrate through the lifting plate and are provided with grinding wheels, and the grinding wheels are located above the second conveyor belt.

[0009] A further improvement of the technical solution of the present invention lies in that: the grinding assembly further includes side plates arranged on both sides of the second conveyor belt. A bearing plate located at the bottom of the second conveyor belt is horizontally arranged between the two side plates. The bearing plate is adapted to the grinding wheel. Guide rods are vertically and fixedly provided at the four corners of the bearing plate, and the guide rods penetrate through the lifting plate and are in sliding fit with the lifting plate.

[0010] A further improvement of the technical solution of the present invention lies in that: a first stop bar is arranged along the conveying direction at the center of each conveyor chain plate, and the first stop bar divides the first conveyor belt into two symmetric first conveying areas.

[0011] A further improvement of the technical solution of the present invention lies in that: the included angle between the inclined conveying surface and the horizontal conveying surface is 120° to 145°. A first shaft roller is arranged on the horizontal conveying surface, and the rotation direction of the first shaft roller is the same as the driving direction of the first conveyor belt. The height of the lowest point of the first shaft roller from the conveyor chain plate is 1.5 times the thickness of the gasket.

[0012] A further improvement of the technical solution of the present invention lies in that: a second stop bar is arranged along the conveying direction at the center of the second conveyor belt, and the second stop bar divides the second conveyor belt into two symmetric second conveying areas. A single row of limiting blocks is evenly arranged on each second conveying area. The diameter of the limiting block matches the inner diameter of the gasket, and the height of the limiting block is less than the thickness of the gasket.

[0013] A further improvement of the technical solution of the present invention lies in that: a rubber coating is provided on the surface of the second conveyor belt, and the static friction coefficient of the rubber coating is 0.6 to 0.8.

[0014] A further improvement of the technical solution of the present invention lies in that: a brush roller is arranged at the front end of the second conveyor belt. A plurality of steel wire bristles are evenly arranged on the brush roller. The rotation direction of the brush roller is the same as the driving direction of the second conveyor belt. The height of the lowest point of the steel wire bristles on the brush roller from the second conveyor belt is 1.2 times the thickness of the gasket.

[0015] A further improvement of the technical solution of the present invention lies in that: a second shaft roller is arranged on the second conveyor belt between the brush roller and the grinding assembly. The rotation direction of the second shaft roller is the same as the driving direction of the second conveyor belt. The height of the lowest point of the second shaft roller from the second conveyor belt is 1.5 times the thickness of the gasket.

[0016] A method for using a gasket grinding device for automotive parts, including the following steps:

[0017] S1: The first conveyor belt receives the gaskets after blanking. After the gaskets fall onto the horizontal conveying surface, they are conveyed forward and pass through the first shaft roller. The rotation direction of the first shaft roller is the same as the transmission direction of the first conveyor belt, giving the gaskets a backward force. And the height of the lowest point of the first shaft roller from the conveying chain plate is 1.5 times the thickness of the gasket. Therefore, the first shaft roller pushes the stacked gaskets apart, so that the gaskets no longer stack, and the first shaft roller cooperates with the first stop strip to make the gaskets move to the first conveying areas on both sides of the first stop strip, dispersing the gaskets;

[0018] S2: The gaskets enter the inclined conveying surface. The first conveyor belt is controlled by a vibration conveying motor. Under the action of vibration and the inclined angle, the gaskets are regularly arranged, and most of the gaskets are clamped in the gaps between adjacent two conveying chain plates, and are clamped by the upwardly warped edges and downwardly pressing edges of the adjacent two conveying chain plates. When the gaskets are transmitted to the lower part of the end of the inclined conveying surface, due to the increase in the gap between the conveying chain plates and the gaskets being inclined downward along the horizontal plane, under the action of their own gravity, the gaskets slide and enter the second conveyor belt. The upwardly warped edges and downwardly pressing edges of the conveying chain plates clamping the gaskets are beneficial to reducing the falling height of the gaskets, slowing down the falling speed of the gaskets, and increasing the probability of the gaskets sliding into the limit blocks of the second conveyor belt;

[0019] S3: The gaskets slide into the second conveyor belt. Most of the gaskets are clamped into the limit blocks, and a small number of gaskets are not in the correct position, stacking or tilting and pressing the limit blocks. When passing through the brush roller, the rotation direction of the brush roller is the same as the transmission direction of the second conveyor belt. The steel wire bristles of the brush roller correct the gaskets that are not in the correct position. During the rotation process, the steel wire bristles can push or flip the inclined gaskets, and at the same time push the gaskets backward until the gaskets are clamped into the limit blocks;

[0020] S4: The gaskets are conveyed forward and pass through the second shaft roller. The function of the second roller shaft is the same as that of the first roller shaft, further correcting the gaskets so that the gaskets are clamped into the limit blocks;

[0021] S5: The gaskets enter directly below the grinding wheel. The second conveyor belt stops periodically. The lifting motor drives the lifting plate to descend, and the rotating motor and the grinding wheel on the lifting plate descend synchronously. The rotating motor controls the grinding wheel to rotate to grind the gaskets. Thus, the single-sided grinding of the gaskets is completed;

[0022] S6: If the gasket needs to be polished on both sides, a set of third conveyor belts is added at the end of the second conveyor belt. The structure of the third conveyor belt is the same as that of the second conveyor belt, and the conveying surface of the third conveyor belt is lower than that of the second conveyor belt. When the gasket moves to the end of the second conveyor belt, due to the structure of the limit block, the gasket will slide off the limit block and enter the third conveyor belt only after the position behind the vertical plane, and at the same time, a 180° turn is completed. The third conveyor belt is also provided with brush rollers and polishing components, and the gasket enters the third conveyor belt for polishing on the other side.

[0023] Adopting the above technical solutions, the present invention has the following beneficial effects:

[0024] 1. A gasket polishing device for automotive parts provided by the present invention is beneficial to reducing burr interference. The conveying chain plate of the first conveyor belt is provided with unique upwardly warped edges and downwardly pressing edges, which form an interleaved structure. When the gasket after blanking passes through the conveying chain plate, the upwardly warped edge scratches the surface of the gasket at an acute angle to peel off burrs and debris; the downwardly pressing edge further compresses the edge of the gasket to clean residual impurities. There is a precise gap between the chain plates, which only allows the gasket to be engaged, while debris and larger burrs naturally fall off from the gap, preventing impurities from entering the polishing area. This dual cleaning mechanism greatly reduces the risk of grinding wheel clogging and surface scratching of the gasket;

[0025] 2. A gasket polishing device for automotive parts provided by the present invention is beneficial to stabilizing the positioning of the gasket. At the end of the inclined conveying surface, the upwardly warped edge and the downwardly pressing edge of the conveying chain plate form an interleaved structure, and with the regular vibration of the vibration motor, the gaskets are arranged regularly, and most of the gaskets are engaged in the gap between two adjacent conveying chain plates. After being engaged by the upwardly warped edge and the downwardly pressing edge of two adjacent conveying chain plates, when the gasket is transmitted to the lower part of the end of the inclined conveying surface, due to the increase in the gap between the conveying chain plates and the gasket tilting downward along the horizontal plane, under the action of its own gravity, it slides and enters the second conveyor belt, which not only controls the falling height of the gasket but also slows down its falling speed to ensure the gasket lands smoothly. The second conveyor belt is provided with limit blocks that fit and match the inner diameter of the gasket, and the gasket is precisely engaged, solving the problem of uneven polishing caused by position deviation in the traditional process.

[0026] 3. A gasket polishing device for automotive parts provided by the present invention is beneficial to eliminating stress concentration in the gasket after blanking. The gasket after blanking passes through the first conveyor belt and the second conveyor belt in sequence, undergoes natural cooling, and releases the internal stress generated by blanking. At the same time, the sliding structure of the bearing plate and the guide rod arranged below the polishing component plays a shock-absorbing role, absorbing the vibration energy when the grinding wheel presses down, avoiding stress deformation, and ensuring that the thickness tolerance of the gasket is stably controlled within ±0.01 mm.

[0027] 4. A gasket grinding device for automotive parts provided by the present invention. This grinding device is beneficial to balancing the time rhythm differences between blanking and grinding, enabling continuous production and improving production efficiency. By adjusting the feeding rhythm of the first conveyor belt through a vibration transmission motor, and cooperating with the sorting of the limit blocks and the dynamic deviation correction of the brush roller on the second conveyor belt, the rhythm differences between blanking and grinding are resolved in the buffer link, increasing the overall efficiency of the production line by more than 40%. The first conveyor belt and the second conveyor belt form an independent buffer system. When the blanking machine or the grinding assembly stops temporarily, the conveyor belt can temporarily store 50 to 100 gaskets, increasing the buffer capacity and avoiding the shutdown of the entire line caused by a single-point failure in the traditional linked production line. The overall equipment operating rate is increased by 25% - 30%. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The present invention will be further explained and described below in conjunction with specific embodiments.

[0044] As Figures 1-10As shown in the figure, a gasket grinding device for automotive parts provided in this embodiment includes a first conveyor belt 1. The first conveyor belt 1 includes a horizontal conveyor surface 11 and an inclined conveyor surface 12 that are sequentially connected along the conveying direction. The included angle between the inclined conveyor surface 12 and the horizontal conveyor surface 11 is 120° to 145°. A first shaft roller 18 is provided on the horizontal conveyor surface 11. The rotation direction of the first shaft roller 18 is the same as the transmission direction of the first conveyor belt 1. The height from the lowest point of the first shaft roller 18 to the conveyor chain plate 14 is 1.5 times the thickness of the gasket. A horizontal second conveyor belt 2 is provided below the conveying end of the inclined conveyor surface 12, and a grinding assembly 3 is provided at the conveying end of the second conveyor belt 2;

[0045] As Figures 1-7As shown, in this embodiment, the first conveyor belt 1 is controlled by a vibrating conveying motor 13, and the first conveyor belt 1 includes a plurality of conveying chain plates 14. A first baffle 17 is arranged on the center upper side of each conveying chain plate 14 along the conveying direction. The first baffle 17 divides the first conveyor belt 1 into two symmetrical first conveying areas. After punching, the gasket enters the horizontal conveying surface 11 of the first conveyor belt 1, is rotated and separated by the first shaft roller 18, and is guided to the conveying areas on both sides by the first baffle 17. An upward rib 15 and a downward pressure rib 16 are respectively arranged on the front and rear sides of each conveying chain plate 14 along the conveying direction. The angle between the upward rib 15 and the conveying chain plate 14 is 120° to 150°, and the upward rib 15 and the downward pressure rib 16 are in opposite directions. The gap between adjacent conveying chain plates 14 is 1.1 times the thickness of the gasket to ensure that only a single layer of gasket is engaged, and the outer diameter of the gasket is smaller than the total width of the two adjacent conveying chain plates 14. The conveying chain plate 14 of the first conveyor belt 1 is provided with a unique upturned rib 15 and a downturned rib 16, which form a staggered structure. When the punched gasket passes through the conveying chain plate 14, the upturned rib 15 scrapes the surface of the gasket at an acute angle to remove burrs and debris; the downturned rib 16 further compacts the edge of the gasket and cleans the residual impurities. A precise gap is designed between the chain plates, which only allows the gasket to engage, while debris and larger burrs fall off naturally from the gap to prevent impurities from entering the grinding area. This double cleaning mechanism greatly reduces the risk of clogging the grinding wheel 307 and scratching the gasket surface. At the end of the inclined conveying surface 12, the upward ribs 15 and the downward ribs 16 of the conveying chain plates 14 form a staggered structure. With the regular vibration of the vibration motor, the gaskets are regularly arranged, and most of the gaskets are engaged in the gap between two adjacent conveying chain plates 14. After the upward ribs 15 and the downward ribs 16 of the two adjacent conveying chain plates 14 are engaged, when the gaskets are transmitted to the lower end of the inclined conveying surface 12, due to the increase in the gap between the conveying chain plates 14 and the gaskets tilting downward along the horizontal plane, they slide down under the action of their own gravity and enter the second conveyor belt 2, which not only controls the falling height of the gaskets, but also slows down their falling speed to ensure that the gaskets land smoothly. The second conveyor belt 2 is provided with a limit block 22 that fits the inner diameter of the gaskets. The gaskets are precisely engaged to solve the problem of uneven grinding caused by position offset in traditional processes.

[0046] like Figure 1 , Figure 4 , Figures 8-10As shown in the figure, in this embodiment, the grinding assembly 3 includes support columns 301 arranged on both sides of the second conveyor belt 2. A horizontal mounting plate 302 is jointly arranged at the tops of the support columns 301. A lifting motor 303 is arranged at the top of the mounting plate 302. The output shaft of the lifting motor 303 penetrates through the mounting plate 302 and is vertically connected to a lifting rod 304. A horizontal lifting plate 305 is fixedly arranged at the end of the lifting rod 304. Two rotating motors 306 are arranged at the top of the lifting plate 305. The output shafts of the rotating motors 306 penetrate through the lifting plate 305 and grinding wheels 307 are arranged. The grinding wheels 307 are located above the second conveyor belt 2. The two grinding wheels 307 are symmetrically installed at the bottom of the lifting plate 305. During grinding, they are synchronously pressed downwards to evenly disperse the acting force, avoiding the deformation of the gasket or the eccentric wear of the grinding wheel 307 caused by single-point pressing. Each grinding wheel 307 is driven by an independent rotating motor 306, supporting differential speed adjustment. The grinding assembly 3 further includes side plates 308 arranged on both sides of the second conveyor belt 2. A bearing plate 309 located at the bottom of the second conveyor belt 2 is horizontally arranged between the two side plates 308. The bearing plate 309 is adapted to the grinding wheel 307. Guide rods 310 are vertically and fixedly arranged at the four corners of the bearing plate 309. The guide rods 310 penetrate through the lifting plate 305 and are in sliding fit with the lifting plate 305. The bearing plate 309 at the bottom of the second conveyor belt 2 is accurately aligned with the position of the grinding wheel 307. During grinding, a rigid support structure of "upper grinding wheel 307 - lower bearing plate 309" is formed, absorbing more than 90% of the vibration energy, and the surface roughness can reach below Ra 0.2μm. The gaskets after blanking pass through the first conveyor belt 1 and the second conveyor belt 2 in sequence, experiencing natural cooling to release the internal stress generated during blanking. At the same time, the sliding structure of the bearing plate 309 and the guide rods 310 arranged below the grinding assembly 3 plays a shock-absorbing role, absorbing the vibration energy when the grinding wheel 307 is pressed downwards, avoiding stress deformation, and ensuring that the thickness tolerance of the gasket is stably controlled within ±0.01mm.

[0047] As Figure 2 , Figure 8 shown in the figure, in this embodiment, a second stop bar 21 is arranged along the conveying direction at the center of the second conveyor belt 2. The second stop bar 21 divides the second conveyor belt 2 into two symmetrical second conveying areas. A single row of limit blocks 22 is evenly arranged on each second conveying area. The diameter of the limit blocks 22 matches the inner diameter of the gasket. The height of the limit blocks 22 is less than the thickness of the gasket. The limit blocks 22 are used to limit the gasket and at the same time avoid affecting the gasket during grinding.

[0048] As Figures 8-10As shown, in this embodiment, a rubber coating is provided on the surface of the second conveyor belt 2, and the static friction coefficient of the rubber coating is 0.6-0.8, which prevents the gasket from rotating during grinding. A brush roller 23 is provided at the transmission front end of the second conveyor belt 2, and a plurality of steel wire bristles 24 are evenly arranged on the brush roller 23. The rotation direction of the brush roller 23 is consistent with the transmission direction of the second conveyor belt 2, and the lowest point of the steel wire bristles 24 on the brush roller 23 is 1.2 times the thickness of the gasket from the second conveyor belt 2. The brush roller 23 dynamically pushes the offset gasket. When the gasket slides to the second conveyor belt 2, if the position is offset due to inertia or collision, the wire bristles 24 of the brush roller 23 lightly touch the edge of the gasket and push it back to the predetermined track. If the gasket is tilted due to the sliding angle problem, the flexible movement of the wire bristles 24 can cause it to flip over, so that the gasket engages the limit block 22. When the brush roller 23 rotates, the wire bristles 24 sweep across the conveyor belt surface at a height of 1.2 times the thickness of the gasket, pushing the stacked gaskets backwards, forcing the overlapping parts to separate and preventing multiple pieces from entering the grinding component 3 at the same time.

[0049] like Figure 4 , Figures 8-10 As shown, in this embodiment, a second shaft roller 25 is arranged on the second conveyor belt 2 between the brush roller 23 and the grinding assembly 3. The rotation direction of the second shaft roller 25 is consistent with the transmission direction of the second conveyor belt 2. The lowest point of the second shaft roller 25 is 1.5 times the thickness of the gasket from the second conveyor belt 2. The gasket falls into the limit block 22 of the second conveyor belt 2. The offset gasket is accurately positioned after being corrected by the brush roller 23 and the second shaft roller 25. The second conveyor belt 2 is periodically paused, and the lifting motor 303 drives the grinding wheel 307 to press down. The double grinding wheels 307 rotate synchronously for grinding. The pressure plate 309 and the guide rod 310 suppress vibration to complete single-sided processing. The grinding equipment is conducive to balancing the time rhythm difference between punching and grinding, continuous production, and improving production efficiency. The feeding rhythm of the first conveyor belt 1 is adjusted by the vibrating transmission motor 13, and the limit block 22 of the second conveyor belt 2 is coordinated for sorting and the brush roller 23 is dynamically corrected to eliminate the rhythm difference between punching and grinding in the buffer link, so that the overall efficiency of the production line is improved by more than 40%; the first conveyor belt 1 and the second conveyor belt 2 form an independent buffer system. When the punching machine or the grinding component 3 is temporarily shut down, the conveyor belt can temporarily store 50 to 100 gaskets, thereby increasing the buffer capacity and avoiding the whole line shutdown due to single point failure of the traditional linkage production line. The comprehensive utilization rate of the equipment is increased by 25% to 30%.

[0050] A method for using a gasket grinding device for automobile parts comprises the following steps:

[0051] S1: The first conveyor belt 1 receives the punched gaskets. After the gaskets fall onto the horizontal conveying surface 11, they are conveyed forward and pass through the first shaft roller 18. The rotation direction of the first shaft roller 18 is the same as the driving direction of the first conveyor belt 1, applying a backward force to the gaskets. Moreover, the height from the lowest point of the first shaft roller 18 to the conveying chain plate 14 is 1.5 times the thickness of the gasket. Therefore, the first shaft roller 18 pushes the stacked gaskets apart, preventing the gaskets from stacking up. Also, the first shaft roller 18 cooperates with the first stop bar 17 to make the gaskets move to the first conveying areas on both sides of the first stop bar 17, dispersing the gaskets.

[0052] S2: The gaskets enter the inclined conveying surface 12. The first conveyor belt 1 is controlled by the vibrating conveying motor 13. Under the action of vibration and the inclined angle, the gaskets are arranged regularly, and most of the gaskets are clamped in the gaps between adjacent conveying chain plates 14 and are clamped by the upwardly warped edges 15 and the downwardly pressing edges 16 of the adjacent conveying chain plates 14. When the gaskets are conveyed to below the end of the inclined conveying surface 12, due to the increase in the gaps between the conveying chain plates 14 and the gaskets being inclined downward along the horizontal plane, under the action of their own gravity, the gaskets slide and enter the second conveyor belt 2. The upwardly warped edges 15 and the downwardly pressing edges 16 of the conveying chain plates 14 clamping the gaskets are beneficial for reducing the falling height of the gaskets, slowing down the falling speed of the gaskets, and increasing the probability of the gaskets sliding into the limit blocks 22 of the second conveyor belt 2.

[0053] S3: The gaskets slide into the second conveyor belt 2. Most of the gaskets are clamped into the limit blocks 22, and a small number of gaskets are not in the correct position, resulting in stacking or tilting and pressing on the limit blocks 22. When passing through the brush roller 23, the rotation direction of the brush roller 23 is the same as the driving direction of the second conveyor belt 2. The wire bristles 24 of the brush roller 23 correct the gaskets that are not in the correct position. During the rotation process, the wire bristles 24 can push or flip the tilted gaskets and at the same time push the gaskets backward until the gaskets are clamped into the limit blocks 22.

[0054] S4: The gaskets are conveyed forward and pass through the second shaft roller 25. The function of the second roller shaft is the same as that of the first roller shaft, further correcting the gaskets so that the gaskets are clamped into the limit blocks 22.

[0055] S5: The gaskets enter directly below the grinding wheel 307. The second conveyor belt 2 stops periodically. The lifting motor 303 drives the lifting plate 305 to descend, and the rotating motor and the grinding wheel 307 on the lifting plate 305 descend synchronously. The rotating motor 306 controls the grinding wheel 307 to rotate to grind the gaskets. Thus, the single-sided grinding of the gaskets is completed.

[0056] S6: If the gasket needs to be polished on both sides, a set of third conveyor belts is added at the end of the second conveyor belt 2. The structure of the third conveyor belt is the same as that of the second conveyor belt 2, and the conveying surface of the third conveyor belt is lower than that of the second conveyor belt 2. When the gasket moves to the end of the second conveyor belt 2, due to the structure of the limit block 22, the gasket will slide off the limit block 22 and enter the third conveyor belt only after the position behind the vertical plane, and at the same time, a 180° turn-over is completed. The third conveyor belt is also provided with a brush roller 23 and a polishing assembly 3, and the gasket enters the third conveyor belt for polishing on the other side.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.

The rotation direction of the second shaft roller (25) is the same as the transmission direction of the second conveyor belt (2). The height from the lowest point of the second shaft roller (25) to the second conveyor belt (2) is 1.5 times the thickness of the gasket.

10. A method for using a gasket grinding device for automotive parts, characterized in that, It includes the following steps: S1: The first conveyor belt (1) receives the punched gaskets. After the gaskets fall onto the horizontal conveying surface (11), they are conveyed forward and pass through the first shaft roller (18). The rotation direction of the first shaft roller (18) is the same as the transmission direction of the first conveyor belt (1), applying a backward force to the gaskets. Moreover, the height from the lowest point of the first shaft roller (18) to the conveyor chain plate (14) is 1.5 times the thickness of the gasket. Therefore, the first shaft roller (18) pushes the stacked gaskets apart, preventing the gaskets from stacking up. Also, the first shaft roller (18) cooperates with the first stop bar (17) to move the gaskets to the first conveying areas on both sides of the first stop bar (17), dispersing the gaskets. S2: The gaskets enter the inclined conveying surface (12). The first conveyor belt (1) is controlled by a vibrating conveyor motor (13). Under the action of vibration and the inclined angle, the gaskets are regularly arranged, and most of the gaskets are engaged in the gaps between adjacent two conveyor chain plates (14) and are clamped by the upwardly curved edges (15) and downwardly curved edges (16) of the adjacent two conveyor chain plates (14). When the gaskets are transmitted to the lower part of the end of the inclined conveying surface (12), due to the increase in the gap between the conveyor chain plates (14) and the gaskets being inclined downward along the horizontal plane and under the action of their own gravity, the gaskets slide and enter the second conveyor belt (2). The clamping of the gaskets by the upwardly curved edges (15) and downwardly curved edges (16) of the conveyor chain plates (14) helps to reduce the falling height of the gaskets, slow down the falling speed of the gaskets, and increase the probability of the gaskets sliding into the limit blocks (22) of the second conveyor belt (2). S3: The gaskets slide into the second conveyor belt (2). Most of the gaskets are engaged in the limit blocks (22), and a small number of gaskets are not in the correct position, resulting in stacking or tilting and pressing on the limit blocks (22). When passing through the brush roller (23), the rotation direction of the brush roller (23) is the same as the transmission direction of the second conveyor belt (2). The steel wire bristles (24) of the brush roller (23) correct the gaskets that are not in the correct position. During the rotation process, the steel wire bristles (24) can push or flip the inclined gaskets and at the same time push the gaskets backward until the gaskets are engaged in the limit blocks (22). S4: The gasket is conveyed forward and passes through the second shaft roller (25). The function of the second shaft roller (25) is the same as that of the first shaft roller (18), further correcting the deviation of the gasket so that the gasket is engaged into the limit block (22); S5: The gasket enters directly below the grinding wheel (307). The second conveyor belt (2) stops periodically. The lifting motor (303) drives the lifting plate (305) to descend. The rotating motor (306) on the lifting plate (305) and the grinding wheel (307) descend synchronously. The rotating motor (306) controls the grinding wheel (307) to rotate to grind the gasket. Thus, the single-sided grinding of the gasket is completed; S6: If the gasket needs to be ground on both sides, a set of third conveyor belts is added at the end of the second conveyor belt (2). The structure of the third conveyor belt is the same as that of the second conveyor belt (2), and the conveying surface of the third conveyor belt is lower than the conveying surface of the second conveyor belt (2). When the gasket moves to the end of the second conveyor belt (2), due to the structure of the limit block (22), the gasket will slide off the limit block (22) and enter the third conveyor belt only after the position behind the vertical plane, and at the same time, a 180° turnover is completed. The third conveyor belt is also provided with a brush roller (23) and a grinding assembly (3). The gasket enters the third conveyor belt for grinding on the other side.
