[0028] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0029] See also Figures 1 to 4 As shown, the present invention discloses a grinding device 100, which is used to receive a workpiece to be ground (not shown) transported from the feeding mechanism 200 and grind the workpiece to be ground. Preferably, the workpiece to be ground is a plastic part. By providing the grinding device 100 connected to the feeding mechanism 200, burrs on the plastic part can be removed to ensure the quality of the finished product. At the same time, the ground workpiece can be directly fed to the subsequent feeding operation, that is, the grinding device 100 is integrated into the feeding process.

[0030] Specifically, the grinding device 100 includes a positioning module 1 and a grinding module 2. In the vertical direction perpendicular to the grinding device 100, the grinding module 2 is located above the positioning module 1. The positioning module 1 is configured to position the workpiece to be ground transported from the feeding mechanism 200 so that the grinding module 2 can grind the workpiece to be ground.

[0031] The positioning module 1 includes a workbench 11 connected to the feeding mechanism 200 and a positioning block 12 movably connected to the workbench 11. In the vertical direction perpendicular to the workbench 11, the positioning block 12 can be activated to move up and down to partially expose the outside of the workbench 11, and form a working area 110 on the workbench 11 for positioning the workpiece to be ground.

[0032] The feeding mechanism 200 is preferably a vibrating plate, and the vibrating plate includes a hopper 201 and a feeding channel 202 connected to the grinding device 100. The feeding channel 202 is connected to the workbench 11. The workpiece to be ground is transported to the workbench 11 through the feeding channel 202 and is restricted to the working area 110 by the positioning block 12. In other words, the positioning block 12 is located on the transportation path of the workpiece to be ground to block and position the workpiece to be ground.

[0033] Preferably, the workbench 11 is provided with a protrusion extending toward the positioning block 12, the protrusion being used to support the workpiece to be ground, and the positioning block 12 is correspondingly provided with a U-shaped groove 121. When the positioning block 12 moves upward, the working area 110 is formed between the protrusion and the U-shaped groove 121. The provision of the U-shaped groove enables the positioning block 12 to clamp the workpiece to be ground on three sides, thereby completely confining it within the working area 110.

[0034] In this embodiment, a mounting portion 1211 for mounting a grinding piece (not shown) is provided at the top of the U-shaped groove 121. In a vertical direction perpendicular to the workbench 11, the mounting portion 1211 is always partially higher than the workbench 11. Preferably, the grinding piece is sandpaper to grind the side wall surface of the workpiece to be ground.

[0035] In the vertical direction perpendicular to the workbench 11, the grinding module 2 is located above the workbench 11 and includes a driving component 21 and a grinding component 22 connected to the driving component 21. The grinding component 22 is opposite to the working area 110 and can approach or move away from the working area 110 under the drive of the driving component 21.

[0036] A transmission rod 23 is connected between the positioning module 1 and the grinding module 2. One end of the transmission rod 23 is connected to the drive assembly 21, and the other end is in transmission connection with the positioning block 12. The positioning block 12, the transmission rod 23, and the grinding assembly 22 can move in the same direction under the drive of the drive assembly 21. Preferably, the drive assembly 21 is a double cylinder to provide driving force for the grinding assembly 22 and the transmission rod 23.

[0037] Generally speaking, before receiving a workpiece to be ground from the feed mechanism 200, the grinding assembly 22 moves away from the work area 110 to provide space for the workpiece to move. At this point, the positioning block 12 moves in the same direction as the grinding assembly 22, exposing at least a portion of the workpiece to be ground outside the worktable 11, thereby blocking the workpiece from its path and confining it within the work area 110. The grinding assembly 22 then moves closer to the work area 110 until it abuts against the upper surface of the workpiece to be ground, thereby grinding the workpiece. At this point, the positioning block 12 also moves toward the interior of the worktable 11, exposing only the assembly portion 1211 to the outside of the worktable 11. The grinding elements mounted on the assembly portion 1211 grind the sidewalls of the workpiece. Therefore, the simultaneous movement of the positioning block 12 and the grinding assembly 22 allows not only the workpiece to be positioned but also the sidewalls of the workpiece to be ground.

[0038] The workpiece to be ground is provided with a positioning hole, and the working area 110 is correspondingly provided with a through-groove 1101. A positioning rod 1102 is housed within the through-groove 1101. The positioning rod 1102 is in transmission connection with the transmission rod 23 and can be moved toward the workpiece to be ground and into the positioning hole under the action of the transmission rod 23. The movement direction of the positioning rod 1102 is opposite to that of the transmission rod 23. In other words, after the positioning block 12 is lowered, the positioning rod 1102 is used to reposition the workpiece to be ground to prevent it from shifting during the grinding process. Preferably, the through-groove 1101 is provided on a protrusion of the workbench 11.

[0039] A movable block 13 is provided in the workbench 11, and the positioning rod 1102 and the transmission rod 23 are respectively abutted against the two ends of the movable block 13. When one of the positioning rod 1102 and the transmission rod 23 moves toward the movable block 13, the movable block 13 is pushed and moves toward the other of the positioning rod 1102 and the transmission rod 23.

[0040] Preferably, the movable block 13 is a T-shaped block, and both ends of the movable block 13 are provided with abutment surfaces 131 that abut against the positioning rod 1102 and the transmission rod 23, respectively. The abutment surfaces 131 are inclined surfaces, and the positioning rod 1102 and the transmission rod 23 are correspondingly provided with pulleys 14. Therefore, the positioning rod 1102 and the transmission rod 23 can slide along the abutment surfaces 131 via the pulleys 14, and the provision of the inclined surfaces also enables the positioning rod 1102 and the transmission rod 23 to push the movable block 13 to move.

[0041] The movable block 13 is provided with a pin 132 extending toward the positioning block 12. The positioning block 12 is correspondingly provided with a slot 122 for the pin 132 to pass through. The slot 122 is tilted and includes a first end 1221 near the positioning rod 1102 and a second end 1222 near the transmission rod 23. In a direction perpendicular to the workbench 11, the first end 1221 is higher than the second end 1222. The slot 122 is tilted, and based on the unchanged horizontal height of the movable block 13, when the pin 132 of the movable block 13 moves from the second end 1222 toward the first end 1221, the positioning block 12 is lowered. When the pin 132 of the movable block 13 moves from the first end 1221 toward the second end 1222, the positioning block 12 is raised. Therefore, the movement of the positioning block 12 is achieved through the transmission cooperation between the transmission rod 23, the movable block 13, and the positioning block 12.

[0042] In this embodiment, the transmission rod 23 only provides a force to push the movable block 13 toward the positioning rod 1102 . Therefore, the transmission rod 23 can only realize the lowering of the positioning block 12 .

[0043] Preferably, an elastic member (not shown) is sleeved on the positioning rod 1102. When the transmission rod 23 moves toward the movable block 13, the movable block 13 is pushed toward the positioning rod 1102, the pin 132 moves from the second end 1222 to the first end 1221, the positioning rod 1102 is lifted and extends into the positioning hole, and the elastic member is compressed. When the transmission rod 23 moves away from the movable block 13, the elastic member resets and drives the positioning rod 1102 to move toward the movable block 13, pushing the movable block 13 toward the transmission rod 23. The pin 132 moves from the first end 1221 to the second end 1222, and the positioning block 12 is partially exposed to the workbench 11. In other words, the movement direction of the movable block 13 is controlled by the reset force of the elastic member on the positioning rod 1102 and the driving force of the driving assembly 21, thereby enabling the positioning block 12 to move in the same direction as the grinding assembly 22.

[0044] In summary, the grinding device 100 of the present invention is provided with a positioning block 12 that can be activated to move up and down to partially expose the outside of the workbench 11, so as to limit the workpiece to be ground transported by the self-feeding mechanism 200 to the working area 110, and grinds it through the grinding component 22 to eliminate burrs on the workpiece to be ground, thereby ensuring the quality of the finished product.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
