[0025] Reference Figures 1-2An automated grinding device includes a worktable 50, a material holding mechanism 10, a conveying mechanism 20, a feeding mechanism 30, and a grinding mechanism 40. The worktable 50 has a feeding station and a processing station. The feeding mechanism 30, used to feed the material to the material holding mechanism 10, is located at the feeding station. The grinding mechanism 40, used to grind the material, is located at the processing station. The material holding mechanism 10 is movably mounted on the worktable 50 via the conveying mechanism 20. The material holding mechanism 10 is used to clamp the material, and the conveying mechanism 20 is used to drive the material holding mechanism 10 to reciprocate between the feeding station and the processing station. The material is fed into the material holding mechanism 10 via the feeding mechanism 30. The conveying mechanism 20 transports the material holding mechanism 10 along with the material to the processing station. At the processing station, the material is ground by the grinding mechanism 40. After processing and unloading, the conveying mechanism 20 transports the material holding mechanism 10 back to the feeding station for the next feeding and processing cycle. Optionally, the automated grinding equipment also includes a housing 60, which is mounted on the worktable 50 and covers the material holding mechanism 10, the conveying mechanism 20, the feeding mechanism 30, and the grinding mechanism 40 to ensure processing safety. The housing 60 is provided with an openable and closable door panel for adjustment operations.

[0026] Reference Figures 3-5 The material holding mechanism 10 includes a roller drive assembly 15 and two roller groups that can move closer to or further away from each other. The roller groups are mounted on a material holding bracket 13. Optionally, the material holding bracket 13 is provided with a protective shell 16 to cover the roller groups and prevent workers from accidentally touching them during operation. Optionally, the material holding bracket 13 is also provided with a clamping drive part 14, which is connected to at least one of the roller groups to drive the two roller groups to move closer to or further away from each other. The clamping drive part 14 can be a cylinder or other structure that can achieve the same effect. The roller drive assembly 15 is connected to at least one of the roller groups, namely a first roller group 11 and a second roller group 12. Each roller group includes multiple rollers whose roller axes are located in the same straight line and are arranged at intervals. The lines connecting the roller axes of the two roller groups are parallel to each other. A material holding space is formed between two adjacent rollers in the first roller group 11, and each roller in the second roller group 12 is located above its respective material holding space. During loading at the loading station, the clamping drive unit 14 drives the second roller group 12 to rise, increasing the height of the holding space. The loading mechanism 30 delivers the workpiece to the corresponding holding spaces of the holding mechanism 10. After loading, the clamping drive unit 14 drives the second roller group 12 to descend until the rollers of the second roller group 12 contact the workpiece in the holding space, ensuring that the workpiece will not detach during processing. The conveying mechanism 20 transports the holding mechanism 10 to the processing station, and the roller drive assembly 15 drives the roller group to rotate, thereby causing the workpiece to rotate in the holding space, ensuring that the end of the workpiece can be uniformly sharpened by the grinding mechanism 40. Optionally, the clamping drive unit 14 can be a cylinder.

[0027] In some embodiments, the rollers of the first roller group 11 are provided with circumferential grooves on their sides, and the rollers of the second roller group 12 are adapted to the grooves. When the work material is fed into the holding space, the two roller groups move closer to each other, and the rollers in the second roller group 12 can extend into the grooves of the first roller group 11, thereby reducing the possibility of the work material deviating from or even leaving the holding space.

[0028] Optionally, the outer side of the rollers in the roller assembly is wrapped with a rubber wear-resistant layer, which reduces the possibility of materials leaving the holding space, lowers the maintenance cost of the roller assembly, and avoids the need for frequent roller replacements.

[0029] In some embodiments, the material holding mechanism 10 includes a drive shaft assembly 153, where the drive shafts of the drive shaft assembly 153 are connected one-to-one with the rollers of the first roller assembly 11. The roller drive assembly 15 includes a motor 151 and a drive belt 152. The motor 151 is connected to one of the drive shafts, driving the drive shaft and the corresponding roller to rotate. The drive belt 152 is mounted on the drive shaft assembly 153 and contacts the drive shafts in the drive shaft assembly 153, thereby driving all drive shafts to rotate in the same direction and at the same speed. This ensures that the material in the material holding space rotates at a uniform speed, avoiding deviation of the material due to different speeds, which could affect processing accuracy. Optionally, the motor 151 is connected to one of the drive shafts via a belt drive assembly. A support wheel assembly 154 is provided below the drive shaft assembly 153. The drive belt 152 is disposed between the drive shaft assembly 153 and the support wheel assembly 154. The support wheel assembly 154 ensures that the drive belt 152 and the drive shafts in the drive shaft assembly 153 are in taut contact, ensuring that the rotational speed of the drive shaft assembly 153 is consistent. Furthermore, a movable adjusting wheel 155 is provided below the support wheel assembly 154. The transmission belt 152 is tensioned and installed on the outside of the support wheel assembly 154 and the adjusting wheel 155. The tension of the transmission belt 152 can be adjusted by adjusting the position of the adjusting wheel 155.

[0030] In some embodiments, the material holding mechanism 10 further includes a base plate 17, which is fixed to the material holding bracket 13, and the rollers of the roller assembly are rotatably mounted on the base plate. The surface of the base plate used to mount the roller assembly forms the side of the material holding space, allowing one end of the workpiece to abut against the base plate, thereby ensuring that the other end of the workpiece is flush and the grinding degree is uniform and controllable. As an optional embodiment, the base plate is made of a wear-resistant material. As another optional embodiment, the base plate is provided with wear-resistant blocks corresponding to the material holding spaces. During grinding, one end of the workpiece can abut against the wear-resistant block to make the ends of each workpiece in the material holding space flush to ensure consistent processing. When the wear-resistant block wears out, the corresponding wear-resistant block can be replaced, without replacing the entire base plate, thus reducing maintenance costs.

[0031] In some embodiments, the conveying mechanism 20 includes a power transmission chain 21 and a guiding mechanism 22. The material holding mechanism 10 is mounted on the worktable 50 via the guiding mechanism 22. The power transmission chain 21 is connected to the material holding mechanism 10 and is used to drive the material holding mechanism 10 to move along the guiding direction of the guiding mechanism 22, so that the material holding mechanism 10 can move in a certain direction to ensure the accuracy of feeding and processing. Optionally, the guiding mechanism 22 includes a guide rail, and the lower part of the material holding mechanism 10 cooperates with the guide rail, so that it can move along the guide rail. The guide rail has a ring structure. After the material of the material holding mechanism 10 is processed at the processing station, the material holding mechanism 10 can continue to move along the processing direction to return to the feeding station, which also saves the space required by the equipment.

[0032] Reference Figure 7 The feeding mechanism 30 includes a clamping part 34 for clamping the workpiece and a feeding drive component 31. The feeding drive component 31 is connected to the clamping part 34. When the workpiece is fed, the feeding drive component 31 drives the clamping part 34 to move toward the holding mechanism 10, thereby sending the workpiece on the clamping part 34 into the holding mechanism 10. After the feeding is completed, the feeding drive component 31 drives the clamping part 34 away from the holding mechanism 10.

[0033] In some embodiments, the clamping part 34 is provided with a retractable positioning member 32, which, after extending, can adapt to and be fixed with the material holding mechanism 10. When the material holding mechanism 10 moves along the processing direction, it can drive the feeding mechanism 30 to move synchronously. The clamping part 34 and the material holding mechanism 10 remain relatively stationary, thus eliminating the need for the material holding mechanism 10 to pause feeding at the feeding station. This improves processing efficiency and enables precise feeding of the workpiece. After the workpiece is fed, the positioning member 32 retracts, and the feeding mechanism 30 no longer follows the material holding mechanism 10 along the processing direction. The material holding mechanism 10 moves independently to the processing station via the conveying mechanism 20. Optionally, the advancing surface of the material holding mechanism 10 moving towards the processing station is provided with a recess, and the positioning member 32, after extending, can abut against the recess. When the material holding mechanism 10 moves toward the processing station, its forward surface that abuts against the positioning component 32 drives the feeding mechanism 30 to move synchronously. Since the positioning component 32 extends out and cooperates with and abuts against the recessed part, the positioning component 32 is not easy to disengage when the material holding mechanism 10 moves, ensuring that the material holding mechanism 10 can remain relatively stationary with the feeding mechanism 30 when moving to feed.

[0034] In some embodiments, the feeding mechanism 30 further includes a feeding plate 33, which is used to place the workpiece to be fed so that the clamping part 34 can pick up the workpiece. Optionally, the top surface of the feeding plate 33 is provided with a plurality of receiving slots 331, which are arranged parallel to each other on the feeding plate 33 at intervals. Each workpiece is placed in a respective receiving slot. The two sides of the receiving slots are provided with widening slots, and the clamping part 34 can extend into the widening slots to facilitate picking up the workpiece.

[0035] In some embodiments, the clamping part 34 includes a mounting plate 341, a longitudinal driving component 342, and clamping claws 343 for clamping the workpiece. The longitudinal driving component 342 is fixed on the mounting plate 341, and its output end is connected to the clamping claws 343. Thus, the longitudinal driving component 342 can drive the clamping claws 343 to move longitudinally, allowing the clamping claws 343 to pick up the workpiece from the material receiving tray. Simultaneously, the height of the clamping claws 343 can be aligned with the material holding mechanism 10 for precise feeding. The mounting plate 341 is connected to the feeding driving component 31. When the feeding driving component 31 is activated, the clamping claws 343 on the mounting plate 341 can move closer to or further away from the material holding mechanism 10, thereby achieving feeding. Further, the number of clamping claws 343 is two or more, and the clamping claws 343 are arranged in parallel at intervals. Each clamping claw 343 corresponds to a material container. Each clamping claw 343 is used to clamp the material in each material container, so as to realize the simultaneous feeding of multiple materials and improve the feeding efficiency.

[0036] In some embodiments, the feeding mechanism 30 further includes a slide 35, which is fixedly mounted on the worktable 50, and the clamping part 34 is slidably mounted on the slide 35 via a sliding mechanism 351. Optionally, the sliding mechanism 351 is a slide rail, and the bottom of the clamping part 34 cooperates with the slide rail. The slide rail can ensure that the clamping part 34 moves relative to the worktable 50 in a defined direction, thereby preventing the material from shifting during feeding and affecting the feeding accuracy.

[0037] Furthermore, the feeding mechanism 30 also includes a reset member 36 fixed on the slide 35, which is connected to the clamping part 34. During material feeding, the clamping part 34 moves with the holding mechanism 10, moving away from its initial position. After feeding, the reset member 36 drives the clamping part 34 back to its initial position at the feeding station, ready for the next batch of material feeding. As an optional implementation, the reset member 36 is a cylinder, with its output end connected to the clamping part 34. After feeding, the cylinder starts, causing its output end to drive the clamping part 34 to reset. Alternatively, the reset member 36 is a spring, with both ends connected to the slide 35 and the clamping part 34 respectively. During feeding, the clamping part 34 moves with the holding mechanism 10, and the spring stretches to store elastic potential energy. After feeding, the positioning member 32 retracts, and the clamping part 34 disengages from the holding mechanism 10 and remains relatively stationary. The spring then returns, causing the clamping part 34 to also return to its initial position.

[0038] In some embodiments, the feeding mechanism 30 further includes a feeding sensor 37, which is electrically connected to the feeding drive component 31. The feeding sensor 37 can be used to detect the relative position of the clamping part 34 and the holding mechanism 10. When the clamping part 34 and the holding mechanism 10 remain relatively stationary, the feeding sensor 37 sends an electrical signal to the feeding drive component 31, which then starts to feed the workpiece from the clamping part 34 to the holding mechanism 10.

[0039] Reference Figure 6 The grinding mechanism 40 includes a grinding wheel tip mechanism 41 and a position adjustment mechanism. The grinding wheel tip mechanism 41 is mounted on the worktable 50 through the position adjustment mechanism. By adjusting the position adjustment mechanism, the relative position of the grinding wheel tip mechanism 41 with respect to the workpiece of the material holding mechanism 10 on the processing station can be changed, thereby adapting to different processing requirements.

[0040] In some embodiments, the position adjustment mechanism includes a telescopic component 42, which can extend and retract along the height direction and be fixed. The grinding wheel tipping mechanism 41 is mounted on the telescopic component 42, and the height of the grinding wheel tipping mechanism 41 relative to the worktable 50 can be adjusted by adjusting the telescopic component 42, thereby adjusting the longitudinal position of the grinding wheel tipping mechanism 41 relative to the workpiece.

[0041] In some embodiments, the position adjustment mechanism includes an angle adjustment component 43, which includes a bracket 431, a spiral mounting bracket 432, and a spiral adjustment knob 433. Both the spiral adjustment knob 433 and the spiral mounting bracket 432 are rotatably mounted on the bracket 431. A grinding wheel tipping mechanism 41 is mounted on the spiral mounting bracket 432. The outer edge of the spiral mounting bracket 432 has teeth, and the spiral adjustment knob 433 meshes with the teeth of the spiral mounting bracket 432. By rotating the spiral adjustment knob 433, the spiral mounting bracket 432 rotates relative to the bracket 431, thereby adjusting the relative angle between the grinding wheel tipping mechanism 41 on the spiral mounting bracket 432 and the workpiece of the material holding mechanism 10. Optionally, the spiral mounting bracket 432 has an arc-shaped through hole, and the bracket 431 has a corresponding arc-shaped threaded groove. When fixing the relative position of the spiral mounting bracket 432 and the bracket 431, a bolt can be passed through the through hole and inserted into the threaded groove for tightening.

[0042] Optionally, the bracket 431 can be mounted on the telescopic component 42, thereby allowing adjustment of the grinding wheel tip mechanism 41 in both height and angle to better adapt to different processing requirements.

[0043] Optionally, the bracket 431 is also provided with an angle scale, and the screw mounting bracket 432 is correspondingly marked. The angle scale is aligned with the outer edge of the screw mounting bracket 432 so that the operator can make accurate fine adjustments and record operating data.

[0044] In some embodiments, the grinding mechanism 40 further includes a grinding sensor 44 for detecting the position of the material holding mechanism 10, and the grinding sensor 44 is electrically connected to the grinding wheel tip mechanism 41. When the grinding sensor 44 detects that the material holding mechanism 10 is about to reach the processing station, the grinding sensor 44 sends an electrical signal to the grinding wheel tip mechanism 41 to start the grinding wheel tip mechanism 41; when the material holding mechanism 10 leaves the processing station, the grinding sensor 44 sends an electrical signal again to shut down the grinding wheel tip mechanism 41.

[0045] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the embodiments.
