DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all 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.

[0026] As Figure 1-2As shown in the figure, the conveying mechanism 1 of the battery cell 9 in this embodiment includes a base 2, a plurality of conveying platforms, a first driving component 41, and a second driving component 42. The plurality of conveying platforms reciprocate along the base 2. The first driving component 41 is used to drive the conveying platform to move in the conveying direction of the battery cell 9, and the second driving component 42 is used to drive the horizontal height of at least one conveying platform to be higher or lower than that of the remaining conveying platforms, so as to avoid interference between the conveying platforms during movement.

[0027] Specifically, in this embodiment, the conveying platform includes a first platform 31 and a second platform 32; when conveying the battery cell 9, the first platform 31 and the second platform 32 move relative to each other. The first driving component 41 is used to drive the first platform 31 and the second platform 32 to move in the conveying direction of the battery cell 9, and the moving directions of the first platform 31 and the second platform 32 are opposite, so as to realize simultaneous transmission of the battery cell 9 and avoid interference. The second driving component 42 is used to drive one of the first platform 31 or the second platform 32 to rise or fall when the first platform 31 and the second platform 32 approach each other to avoid the remaining platform. The second driving component 42 is fixed below the second platform 32 and moves with the second platform 32.

[0028] The first driving component 41 includes a first driver 101 and a synchronous belt 102. The first driver 101 is used to drive the synchronous belt 102 to rotate reciprocally, and each conveying platform is fixedly connected to the synchronous belt 102. The first platform 31 and the second platform 32 are respectively fixed on both sides of the synchronous belt 102, so as to realize driving by one first driver 101 and then drive the first platform 31 and the second platform 32 to move in opposite directions, realizing alternating transmission. The first platform 31 and the second platform 32 form a pair of linkage mechanisms, which are driven by the first driver 101 and the synchronous belt 102 to move synchronously and in opposite directions.

[0029] In this embodiment, the length of the first platform 31 is greater than the length of the second platform 32. The second driving component 42 is used to drive the second platform 32 to descend when the first platform 31 and the second platform 32 approach each other, so that the horizontal height of the second platform 32 is lower than that of the first platform 31. When the second platform 32 is lower than the first platform 31, the upper surface of the second platform 32 is at least lower than the lower surface of the first platform 31 by more than the thickness of one battery cell 9 to avoid interference.

[0030] As Figure 2 and Figure 3 shown in the figure, in this embodiment, the second platform 32 includes a fixing plate 51 and a moving plate 52. The moving plate 52 is located above the fixing plate 51. The second driving component 42 is used to drive the moving plate 52 to rise or fall relative to the fixing plate 51. The horizontal height of the fixing plate 51 remains unchanged, and it is always lower than the first platform 31 and is fixedly connected to the synchronous belt 102. The moving plate 52 is used for up and down movement.

[0031] To further ensure the stability of the movable plate 52 during its up-and-down movement, guide rods 53 extending in the up-and-down direction are provided at the four corners of the movable plate 52. The upper ends of the guide rods 53 are fixed to the movable plate 52, and the lower ends of the guide rods 53 penetrate through the fixed plate 51 and extend downward to guide the up-and-down movement of the movable plate 52. Preferably, the lower ends of the guide rods 53 are fixedly connected together through a connecting block 54.

[0032] In this embodiment, to ensure the stability of the movement of the transfer platform, a slide rail 71 extending in the conveying direction of the battery cell 9 is provided on the base 2, and a slider 72 cooperating with the slide rail 71 is provided at the end of the transfer platform. The slide rail 71 and the slider 72 cooperate to guide the movement of the transfer platform and ensure the stability of the conveyance. Specifically, sliders 72 and corresponding slide rails 71 are provided at both ends in the length direction of the first platform 31 and the second platform 32. Since the length of the first platform 31 is greater than the length of the second platform 32, the distance between the two slide rails 71 corresponding to the first platform 31 is greater than the distance between the two slide rails 71 corresponding to the second platform 32. The two slide rails 71 on the side of the first platform 31 and the second platform 32 close to the synchronous belt 102 are respectively located on both sides of the synchronous belt 102, so as to drive the synchronous belt 102 to rotate through the first driver 101, and then drive the first platform 31 and the second platform 32 to move in opposite directions, as Figure 4 shown.

[0033] A plurality of receiving stations 6 for carrying the battery cells 9 and a third driving assembly 43 for driving the receiving stations 6 to move relative to the transfer platform are provided on each transfer platform. Moreover, relative movement can also be achieved between the plurality of receiving stations 6 on the same transfer platform to further improve the transmission efficiency. The receiving station 6 in this embodiment is a vacuum adsorption station, which is used to adsorb the battery cell 9 while transmitting the battery cell 9 to prevent the battery cell 9 from falling.

[0034] Since a plurality of receiving stations 6 for carrying the battery cells 9 are provided on each transfer platform, multiple battery cells 9 can be received simultaneously, or after receiving one battery cell 9, the third driving assembly 43 drives the receiving station 6 carrying the battery cell 9 to move, and drives the receiving station 6 without carrying the battery cell 9 to move to the lower part of the receiving position to receive the battery cell 9. After all the receiving stations 6 on this platform receive the battery cells 9, this transfer platform moves towards the grasping position of the battery cell 9. The receiving position and the grasping position are respectively located at both ends of the base 2.

[0035] In this embodiment, a positioning strip 81 is provided at the end of the transfer platform, and a positioner 82 is provided on the base 2. The positioning strip 81 and the positioner 82 cooperate to position the transfer platform, such as positioning the receiving position of the battery cell, the grasping position, and the position where the second platform 32 needs to rise or fall, etc.

[0036] The working process of the conveying mechanism 1 of the battery cell 9 in this embodiment is briefly described as follows:

[0037] After the receiving table 6 on the first platform 31 receives the battery cell 9 at one end of the slide rail 71 (receiving position), it moves towards the other end of the slide rail 71 (grabbing position) driven by the first driving component 41 and waits for the next process or blanking.

[0038] At the same time, since the first platform 31 and the second platform 32 are respectively fixed on both sides of the synchronous belt 102, while the first platform 31 moves, the second platform 32 moves in the opposite direction. When the first platform 31 and the second platform 32 approach each other, the second driving component 42 controls the moving plate 52 of the second platform 32 to move downward, so that the horizontal height of the moving plate 52 is lower than that of the first platform 31.

[0039] When the second platform 32 moves to the receiving position of the battery cell 9, or approaches the receiving position of the battery cell 9, the second driving component 42 controls the moving plate 52 of the second platform 32 to move upward to receive the battery cell 9 at the same height.

[0040] After all the receiving tables 6 on the second platform 32 receive the battery cells 9 and the battery cells 9 on the receiving tables 6 of the first platform 31 are removed, driven by the first driving component 41, the first platform 31 and the second platform 32 move in the direction opposite to the above direction, that is, the second platform 32 moves towards the grabbing position of the battery cell 9, and the first platform 31 moves towards the receiving position of the battery cell 9. When the first platform 31 and the second platform 32 approach each other, the second driving component 42 controls the moving plate 52 of the second platform 32 to move downward.

[0041] When the second platform 32 moves to the grabbing position of the battery cell 9, or approaches the grabbing position of the battery cell 9, the second driving component 42 controls the moving plate 52 of the second platform 32 to move upward to wait for the battery cell 9 to be grabbed at the same height.

[0042] The above steps are continuously repeated to realize the continuous conveying of the battery cell 9.

[0043] The conveying mechanism 1 of the cell 9 in this embodiment realizes the reciprocating movement of the conveying platforms by setting a plurality of conveying platforms that reciprocate along the base 2 and enabling at least one conveying platform to be higher or lower than the remaining conveying platforms, so as to avoid interference between the conveying platforms. Then, the cell 9 is conveyed simultaneously, making part of the transportation time parallel, leaving sufficient time for the stable production capacity of the equipment and improving the transmission efficiency of the cell 9. A height difference is formed between the first platform 31 and the second platform 32. At the same time, the first platform 31 and the second platform 32 are driven to move synchronously and run in opposite directions by a synchronous belt 102 and a driver, ensuring stability and safety.
