Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0025] Embodiment 1

[0026] A positioning device for recycling and disassembling waste electrical appliances, including a base 1, a workbench 2 is rotatably arranged on the top of the base 1, a handle 3 is arranged on the side of the workbench 2, four positioning mechanisms are arranged on the workbench 2, a bracket 4 is arranged inside the workbench 2, and a traction mechanism for driving the positioning mechanism is arranged on the bracket 4;

[0027] The positioning mechanism includes a sliding groove 5, a positioning rod 6 and a limiting ring 7. The sliding groove 5 is arranged on the surface of the workbench 2, and the four sliding grooves 5 are centrosymmetric about the center of the workbench 2. The limiting ring 7 is fixed on the surface of the positioning rod 6. The positioning rod 6 is slidably arranged in the sliding groove 5. The top of the limiting ring 7 abuts against the edge of the sliding groove 5. The bottom of the positioning rod 6 is slidably arranged on the surface of the bracket 4 through a guiding structure. The traction mechanism includes a motor 8, a main shaft 9, a rack 10 and a gear 11. The motor 8 is fixed at the bottom of the bracket 4. The main shaft 9 is rotatably arranged between the workbench 2 and the bracket 4. The four gears 11 are arranged on the surface of the main shaft 9. The four racks 10 are respectively fixed on the surfaces of the four positioning rods 6. The heights of the four racks 10 decrease arithmetically in the counterclockwise direction, and the tolerance between the heights of two adjacent racks 10 is equal to the thickness of the rack 10.

[0028] Please refer to Figure 2 , the motor 8 can drive the main shaft 9 to rotate. When the main shaft 9 rotates, it can drive the gears 11 to rotate synchronously. When the gears 11 rotate, they can drive the positioning rod 6 to move towards the direction close to the main shaft 9 through the rack 10. At this time, the positioning rod 6 can linearly move inside the sliding groove 5, so as to realize the positioning of the waste electrical appliances through the positioning rod 6. Since the heights of the four racks 10 are different, the four racks 10 can be driven by the four gears 11 at the same time, that is, it means that the strokes of the four positioning rods 6 are the same. Therefore, some circular or square waste electrical appliances can be positioned, and there will be no external force acting on the waste electrical appliances when the staff disassemble the waste electrical appliances, which is convenient for the staff to apply force to the tools.

[0029] The guiding structure includes a groove 16 and a guiding rod 17. The guiding rod 17 is fixed on the surface of the bracket 4. The groove 16 is arranged at the bottom of the positioning rod 6. The top of the groove 16 abuts against the top surface of the guiding rod 17. A rotating shaft 18 is rotatably arranged at the top of the groove 16. A roller 19 is fixedly arranged at the lower end of the rotating shaft 18. The side surface of the roller 19 is in contact with the side surface of the guiding rod 17.

[0030] Please refer to Figure 4 , when the positioning rod 6 moves, it can move synchronously on the surface of the guiding rod 17 through the groove 16. The guiding rod 17 can play a guiding role for the positioning rod 6 from the bottom of the positioning rod 6 in cooperation with the sliding groove 5. When the positioning rod 6 moves, it can drive the roller 19 to move synchronously through the rotating shaft 18. At this time, since the roller 19 is in contact with the side surface of the guiding rod 17, there will be friction between the roller 19 and the guiding rod 17. This frictional force can drive the roller 19 to rotate, so that the bottom of the positioning rod 6 will not get stuck during movement.

[0031] Embodiment 2

[0032] The above solution realizes the positioning of waste electrical appliances through four simultaneously moving positioning rods 6. However, the strokes of the four positioning rods 6 are the same, and it is difficult to position non-square waste electrical appliances. Therefore, in this embodiment, a clutch structure is provided between the gear 11 and the main shaft 9. The clutch structure includes a cavity 12, a spring 13, a locking block 14, and a locking groove 15. The cavity 12 is provided on the surface of the main shaft 9, the locking groove 15 is provided on the inner wall of the gear 11, the locking block 14 is slidably arranged in the locking groove 15, the spring 13 is fixed between the locking groove 15 and the locking block 14, one end of the locking block 14 abuts against the inside of the locking groove 15, the locking block 14 is set as a hemisphere, one end of the locking block 14 is located in the cavity 12, and the inner wall of the locking groove 15 is set as the spherical surface of the remaining part of the locking block 14.

[0033] Please refer to Figure 3 , when the main shaft 9 rotates, it can drive the spring 13 and the locking block 14 to rotate synchronously through the cavity 12. At this time, since one end of the locking block 14 is located in the locking groove 15, the locking block 14 can drive the gear 11 to rotate synchronously with the main shaft 9 through the locking groove 15, thereby realizing the driving of the gear 11 on the rack 10. When non-square waste electrical appliances are placed on the workbench 2, at first, the four positioning rods 6 move synchronously under the drive of the four gears 11 and the racks 10 respectively. When one or several of the positioning rods 6 come into contact with the waste electrical appliances, the positioning rods 6 are blocked and cannot continue to move, but the remaining positioning rods 6 are not blocked. Therefore, the remaining positioning rods 6 can continue to move. For the main shaft 9, the main shaft 9 needs to rotate continuously. In this process, the rack 10 below the blocked positioning rod 6 also cannot continue to move, so the corresponding gear 11 cannot rotate either. At this time, the main shaft 9 will drive the locking block 14 to rotate forcibly through the spring 13, and then one end of the locking block 14 will disengage from the inside of the locking groove 15. The result is that the four positioning rods 6 can fit on the side of the waste electrical appliances according to the specific shape of the waste electrical appliances to realize the positioning of the waste electrical appliances.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
