[0023] The following is combined with Figure 1-4 This application is described in further detail.

[0024] The embodiment of the present application discloses a composite multi-layer automatic loading rack. Figures 1 to 4A composite multi-layer automatic loading rack includes a mounting frame 1 disposed on the ground. A plurality of trays 11 for placing workpieces to be polished are slidably connected to the mounting frame 1. Multiple trays 11 are vertically arranged along the mounting frame, with the upper surface of the lower tray 11 abutting the lower surface of the upper tray 11. A conveying assembly 2 and a pushing mechanism 3 are also provided on the mounting frame 1. The conveying assembly 2 is used to transport the workpieces on the trays 11. The pushing mechanism 3 is used to push the trays 11 onto the conveying assembly 2 and simultaneously push the workpieces on the conveying assembly 2 into the clamping assembly of the polishing assembly. The workpieces are then polished by the polishing assembly, thereby achieving the purpose of automatic loading.

[0025] Reference Figures 1 to 4 A limiting slot 12 is provided on the mounting frame 1, and the limiting slot 12 includes a vertical portion 121 and a horizontal portion 122. The horizontal portion 122 and the vertical portion 121 are vertically arranged and connected. At the same time, a limiting block 13 is slidably connected in the limiting slot 12, and the limiting block 13 is fixed to the side of the tray 11. When the tray 11 moves in the vertical direction, the limiting block 13 slides in the vertical portion 121, and then when the limiting block 13 moves to the connection point between the vertical portion 121 and the horizontal portion 122, the limiting block 13 can be pushed to slide in the horizontal direction under the action of the pushing mechanism 3, and finally it is convenient to move the tray 11 to the top of the conveying component 2.

[0026] Reference Figures 1 to 4 A feed port 6 is provided on the mounting frame 1, the opening 7 of the feed port 6 faces the ground, and the feed port 6 is connected to the horizontal portion 122. When the pushing mechanism 3 pushes the limit block 13 to correspond to the feed port 6, the tray 11 is above the conveying assembly 2. At this time, the tray 11 falls from the feed port 6 to the conveying assembly 2 under the action of gravity, and finally the position of the workpiece on the tray 11 is adjusted by the conveying assembly 2.

[0027] Reference Figures 1 to 4 The conveying assembly 2 includes a conveying roller 21 rotatably connected to the mounting frame 1 and a conveying belt 22 wound around the conveying roller 21. The moving direction of the conveying belt 22 is perpendicular to the direction in which the pushing mechanism 3 pushes the workpiece to move. At the same time, a baffle 23 is provided on the mounting frame 1. The baffle 23 is provided along the moving direction of the conveying belt 22, and a feed port 24 is opened on the baffle 23. When the workpiece on the tray 11 corresponds to the feed port 24, the pushing mechanism 3 is used to push the workpiece on the tray 11 to the position of the grinding assembly.

[0028] Reference Figures 1 to 4The pushing mechanism 3 includes a first pushing assembly 4 and a second pushing assembly 5. The first pushing assembly 4 includes a first pushing cylinder 41 fixed on the mounting frame 1, a second pushing cylinder 42 fixed on the piston rod of the first pushing cylinder 41, and a pushing plate 43 fixed on the second pushing cylinder 42. The extension and retraction directions of the first pushing cylinder 41 and the second pushing cylinder 42 are vertically arranged. When the first pushing cylinder 41 moves toward the direction close to the conveying assembly 2, the second pushing cylinder 42 extends the pushing plate 43. At this time, the first pushing cylinder 41 drives the second pushing cylinder 42, the pushing plate 43 and the bottom tray 11 to move toward the conveyor belt 22. At this time, the limit block 13 slides in the horizontal part 122. When the tray 11 moves to the top of the conveyor belt 22, the second pushing cylinder 42 drives the pushing plate 43 to move in the vertical direction away from the tray 11, thereby avoiding the reverse push of the bottom tray 11.

[0029] Reference Figures 1 to 4 The second pushing assembly 5 includes two pushing rollers 51 rotatably connected to the mounting frame 1, a pushing belt 52 wound around the pushing rollers 51, and two supporting rollers 53 rotatably connected to the mounting frame 1. The two supporting rollers 53 are arranged below the two pushing rollers 51, and the distance between the two supporting rollers 53 is smaller than the distance between the two pushing rollers 51. In this embodiment, the moving direction of the pushing belt 52 and the moving direction of the conveyor belt 22 are perpendicular to each other, so that the workpiece on the conveying assembly 2 can be transported to the position of the grinding assembly.

[0030] Reference Figures 1 to 4 Since the distance between the two support rollers 53 is smaller than the distance between the two push rollers 51, the push belt 52 will present an inclined portion 54 on the mounting frame 1, which will finally facilitate the workpiece to move to the bottom of the push belt 52. A plurality of control plates 55 are provided on the push belt 52, and a plurality of push plates 43 are evenly spaced along the circumference of the push belt 52. When the pallet 11 with the workpiece moves onto the conveyor belt 22, the push plate 43 will push the workpiece to move, and then push the workpiece to the position of the grinding assembly; in order to facilitate the control plate 55 to push the workpiece to move, a support plate 61 is provided under the push belt 52, and the support plate 61 is fixed on the mounting frame 1. The workpiece pushed out from the feed port 24 moves to the support plate 61, and then the workpiece on the support plate 61 is pushed to move under the action of the control plate 55. In addition, due to the movement of the conveyor belt 22, the position of the tray 11 can be adjusted so that each workpiece corresponds to the feed port 24 in turn, so that the workpieces at different positions on the tray 11 can be moved in turn to the clamping assembly on the grinding assembly under the action of the second pushing assembly 5, and the workpiece is fixed by the clamping assembly on the grinding assembly. Since the clamping assembly belongs to the existing technology, the clamping assembly will not be described in detail here.

[0031] Reference Figures 1 to 4The tray 11 is provided with a plurality of partitions 62, the number of which can be selected as needed. The workpiece is placed between two partitions 62 and, under the action of the second push assembly 5, is pushed from the feed port 24 to the support plate 61 and finally to the grinding assembly position. Furthermore, an opening 7 is provided at the end of the vertical portion 121 of the mounting frame 1 away from the horizontal portion 122, thereby facilitating the movement of the stop block 13 into the horizontal portion 122.

[0032] In this embodiment, a servo motor is provided on the mounting frame 1, and the output shaft of the servo motor is connected to one of the pushing rollers 51, so that the pushing belt 52 can be driven to move, and the moving speed of the pushing belt 52 can also be adjusted; at the same time, a servo motor is also provided on the mounting frame 1, and the servo motor is used to drive the conveying roller 21 to rotate. Through the setting of the servo motor, the rotation speed of the conveying belt 22 can be adjusted as needed, and the conveying belt 22 can also be made to move intermittently.

[0033] The implementation principle of a composite multi-layer automatic loading rack in the embodiment of the present application is as follows: the staff first places multiple push trays loaded with workpieces on the mounting frame 1. At this time, multiple limit blocks 13 are all in the vertical portion 121, and the upper surface of the lower tray 11 abuts against the lower surface of the upper push tray. After the tray 11 is placed, the second pushing cylinder 42 drives the pushing plate 43 along the vertical direction and moves toward the tray 11, while abutting against the side of the tray 11. Then, the first pushing cylinder 41 moves, driving the second pushing cylinder 42 and the pushing plate 43 to move at the same time. When the pushing plate 43 moves, it also drives the tray 11 to move, so that the tray 11 moves to the conveyor belt 2 2, at this time the limit block 13 and the discharge port correspond and then the tray 11 with the material will fall onto the conveyor belt 22. At this time, the tray 11 on the conveyor belt 22 does not correspond to the feed port 24. Then, the tray 11 is driven to move by conveying, so that the workpiece on the tray 11 corresponds to the feed port 24. At this time, the push belt 52 is rotated to make the control board 55 push the workpiece to move to the bottom of the grinding assembly, and it is fixed by the clamping assembly. Then, the operation is cyclically operated in sequence to achieve the purpose of automatic loading. In addition, in the process of the tray 11 being conveyed downward, the staff can put the tray 11 with the workpiece on the mounting frame 1 from above to facilitate subsequent loading, thereby increasing the loading speed.

[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
