Description

Technical Field

[0001] The utility model relates to the technical field of parts processing, in particular to a loading and unloading circulation mechanism. Background Art

[0002] During the processing and assembly of battery electrodes, in order to adapt to the automated assembly line, the loading and unloading of the electrodes are designed as a loading and unloading mechanism, which moves horizontally to the assembly line to achieve the loading of the electrodes.

[0003] The existing loading and unloading mechanism includes a workbench, one end of which is the loading end and the other end is the unloading end. The unloading end is connected to the assembly line, and the loading end loads the electrode through a robot. The workbench is also provided with a material box that travels back and forth between the loading end and the unloading end, which is used to carry the electrode and transport the electrode from the loading end to the unloading end. To avoid interference, only one material box is set on the workbench. When the material in the material box is emptied, it is returned from the unloading end to the loading end for loading. In the process of waiting for loading, the loading of the assembly line generates a waiting period. It is necessary to wait until the material box is refilled and returned to the unloading end before the assembly line can reload and start working. This results in slow production efficiency and inability to load and unload materials synchronously. Utility Model Content

[0004] The purpose of the utility model is to provide a loading and unloading circulation mechanism capable of loading and unloading materials synchronously, thereby improving production efficiency.

[0005] The technical solution of the present utility model is: a loading and unloading circulation mechanism, including a workbench with a loading end and a unloading end, a first material box provided on the workbench and moving back and forth between the loading end and the unloading end, and a second material box provided on the workbench and moving back and forth between the loading end and the unloading end, the bottom of the second material box is provided with a lifting mechanism for driving the second material box to rise and fall, and a sliding cavity is provided below the first material box for realizing the position exchange of the first material box and the second material box on the workbench in a penetrating manner after the second material box descends.

[0006] In the above scheme, a second material box is added, and the second material box is connected in a lifting manner. After it descends, during the movement with the first material box, the two realize the exchange of positions on the same work surface. That is, when one of the material boxes needs to return to the loading end after being empty, the other material box filled with material is replaced at the unloading end, avoiding waiting of the assembly line (production line), ensuring and improving production efficiency, and realizing the synchronous loading and unloading.

[0007] Preferably, a sliding cavity adapted to the second material box is provided below the first material box, and the sliding cavity is through-connected at both ends in the moving direction of the second material box.

[0009] Preferably, the loading and unloading circulation mechanism also includes a driving mechanism for driving the first material box and the second material box to move back and forth, and the driving mechanism includes a driving source, a synchronous wheel, a pressure block and a synchronous belt. The synchronous wheels are rotatably arranged on the workbench and are respectively close to the loading end and the unloading end. There are two of them. The driving source is installed on the workbench and is driven and connected to one of the synchronous wheels. The synchronous belt rotates on the two synchronous wheels, and the synchronous belt is provided with two pressure blocks respectively connected to the first bracket and the second bracket.

[0014] Compared with the related art, the beneficial effects of the present invention are:

[0015] First, the utility model adds a second material box, and the second material box is connected in a lifting manner. After the second material box is lowered, the two realize position swapping during the movement with the first material box. That is, when one of the material boxes needs to return to the loading end after being empty, the other material box filled with material is replaced at the unloading end, thereby avoiding waiting of the assembly line (production line), ensuring and improving production efficiency, and realizing synchronous loading and unloading.

[0020] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments and features of the embodiments of the present invention may be combined unless they conflict. For ease of description, the words "upper," "lower," "left," and "right" appear below merely to indicate the directions of upper, lower, left, and right in the accompanying drawings and do not limit the structure.

[0021] like Figure 1 As shown, a loading and unloading circulation mechanism provided in this embodiment includes a first sensor 1, a second sensor 2, a second material box 3, a slot-type photoelectric 4, a first linear guide rail 5, a second linear guide rail 6, a lifting mechanism 7, a driving mechanism 8, a tensioning adjustment block 9, a first material box 14, a slider 16, a stop block 17, a workbench 18, a first bracket 19, a second bracket 20 and a sliding cavity 23.

[0022] One end of the workbench 18 is a loading end 21, and the other end is a unloading end 22. The unloading end 22 is connected to the production line. Robots are provided at the loading end 21 and the unloading end 22 for grabbing the electrode 25.

[0023] The workbench 18 is provided with two parallel first linear guides 5 and two parallel second linear guides 6. The two first linear guides 5 are located outside the two second linear guides 6. The workbench 18 is provided with at least two slot-shaped photoelectric sensors 4, one of which is located near the loading end 21 and one of which is located near the unloading end 22. The slot-shaped photoelectric sensor 4 is located outside one of the first linear guides 5.

[0024] The first material box 14 and the second material box 3 have the same structure, and are both provided with a cavity for placing the electrode pieces 25 , and a plurality of electrode pieces 25 can be stacked and placed in each cavity.

[0025] The lower end of the first magazine 14 is connected to a first bracket 19. A slider 16 is provided at the bottom of the first bracket 19, adapted to fit within the first linear guide 5. The first bracket 19 elevates the first magazine 14, creating a sliding cavity 23 beneath it. This cavity 23 allows the second magazine 3 to slide through. The slider 16 on the first bracket 19 allows the first magazine 14 to move back and forth between the loading end 21 and the unloading end 22 along the first linear guide 5.

[0026] The lifting mechanism 7 is mounted on the second bracket 20. A slider 16 is provided at the bottom of the second bracket 20, adapted to fit the second linear guide 6. The lifting mechanism 7 is a slide cylinder, the drive end of which is operatively connected to the second magazine 3. The slider 16 on the second bracket 20 allows the second magazine 3 to move back and forth between the loading end 21 and the unloading end 22 along the first linear guide 5. The lifting mechanism 7 is used to drive the second magazine 3 up and down.

[0027] The ends of the first linear guide rail 5 and the second linear guide rail 6 are both provided with a stopper 17 , which is a high-strength rubber block that limits the movement trajectory of the slider 16 to prevent the slider 16 from leaving the guide rail during movement.

[0028] The two material boxes are respectively arranged at the loading end 21 and the unloading end 22. The material box at the loading end 21 is used for loading, and the material box at the unloading end 22 is used for unloading to the assembly line. The workbench 18 is provided with a first sensor 1 and a second sensor 2 for respectively sensing the materials inside the first material box 14 and the second material box 3. The first sensor 1 is arranged close to the loading end 21, and the second sensor 2 is arranged close to the unloading end 22. The first sensor 1 and the second sensor 2 are both through-beam sensors, wherein the first sensor 1 close to the loading end 21 is used to sense whether the material in the cavity of the material box at this position is flat. Otherwise, it is corrected until it is flat. The second sensor 2 close to the unloading end 22 is used to sense whether there is material in the cavity of the material box at this position. If not, it is necessary to start the instruction to exchange the position of the material box.

[0029] The workbench 18 is provided with a slotted hole, the extending direction of which coincides with the moving direction of the magazine. A tensioning adjustment block 9 is mounted at the slotted hole. The tensioning adjustment block 9 moves along the slotted hole, and its moving position is fixed to the workbench 18 by fasteners.

[0030] The drive mechanism 8 is used to drive the reciprocating movement of the first and second magazines 14 and 3. The drive mechanism 8 comprises a drive source 24, synchronous pulleys 12, pressure blocks 13, and a synchronous belt 15. Two synchronous pulleys 12 are rotatably mounted on the workbench 18, one near the loading end 21 and the other near the unloading end 22. The drive source 24 is mounted on the tensioning block 9. The drive source 24 comprises a motor 11 and a reducer 10 connected to the motor 11. The output end of the reducer 10 is connected to one of the synchronous pulleys 12, which is rotatably mounted on the tensioning block 9. The synchronous belt 15 rotates around the two synchronous pulleys 12 and is equipped with two pressure blocks 13, which are connected to the first and second brackets 19 and 20, respectively. The rotating synchronous belt 15 has inner and outer edges: the inner edge is connected to the second bracket 20, and the outer edge is connected to the first bracket 19. This enables bidirectional movement of the first and second magazines 14 and 3 relative to or away from each other. The position of one of the synchronous wheels 12 is adjusted by the tensioning adjusting block 9 to adjust the tension of the synchronous belt 15 .

[0031] To swap positions, the lifting mechanism 7 is activated to lower the second magazine 3. The drive source 24 in the drive mechanism 8 is activated, causing the timing belt 15 to synchronously drive the first and second magazines 14 and 3 in relative motion, allowing the second magazine 3 to pass through the slide cavity 23 in the first magazine 14, thus swapping positions. To reverse the position, the drive source 24 is activated, causing the first and second magazines 14 and 3 to move away from each other, completing the position swap. The lifting mechanism 7 is then activated to raise the second magazine 3 into the manipulator's operating range.

[0032] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
