This transfer frame is mainly used for transfer and storage in the production of lithium battery negative electrode sheets. It has a simple structure and can neatly store the stacks of negative electrode sheets, effectively preventing the sheets from falling off. It can also effectively avoid the messy problem of adjacent stacks of electrodes crossing each other due to stacking offset. It is easy to take and improves work efficiency.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a transport frame for negative electrode sheets of a lithium battery, comprising an outer frame 1, grooves 11 are provided at both ends of the outer frame 1, and a clamping component for facilitating layering is fixedly connected to the inner part of the upper end of the outer frame 1, an elastic component for facilitating ejection is fixedly connected to the outer end of the lower side of the clamping component, and a limiting component for facilitating protection is arranged on the upper side of both ends of the clamping component. When the negative electrode sheets are transported, the negative electrode sheets can be placed in a single layer on the lower side of the clamping component, and then the clamping component is inserted into the outer frame 1 with the assistance of the elastic component to limit the neatly placed negative electrode sheets, and then the limiting component can be used to clamp the clamping component. When the transport frame transports the negative electrode sheets of the lithium battery, the placed negative electrode sheets can be clamped, thereby limiting them and preventing them from shaking too much.

[0022] like Figure 1 and Figure 2 As shown, an inner frame 5 is fixedly connected to the middle end of the upper side of the positioning assembly, and a splitting assembly is fixedly connected to the inner side of the inner frame 5. When placing the negative electrode sheets of the lithium battery, they are placed in the splitting assembly one by one, and the stacked negative electrode sheets are split again using the splitting assembly to facilitate subsequent taking.

[0023] like Figure 2 As shown, the locking assembly includes a first partition plate 2 inserted inside the outer frame 1, and a locking plate 21 is attached to the lower sides of both ends of the first partition plate 2, the end of the locking plate 21 away from the first partition plate 2 is inserted in the outer frame 1, and a first spring 22 is fixedly connected to the outer side of the end of the locking plate 21 inserted in the first partition plate 2, and the end of the first spring 22 away from the locking plate 21 is fixedly connected to the outer frame 1. When the first partition plate 2 is inserted, the locking plates 21 on both sides are squeezed, so that the locking plates 21 are squeezed and inserted into the outer frame 1 to compress the first spring 22. After waiting for the first partition plate 2 to be inserted, the first spring 22 pushes the locking plate 21 to pop out, so that the locking plate 21 restricts the first partition plate 2, so as to facilitate the locking of the upper side of the first partition plate 2.

[0024] like Figure 4 As shown, the elastic component includes a sleeve 3 fixedly connected to the lower sides of both ends of the first partition plate 2, and a plug plate 31 is inserted inside the lower end of the sleeve 3, a second spring 32 is fixedly connected to the upper side of the plug plate 31, and the upper end of the second spring 32 is fixedly connected to the sleeve 3, a push rod 33 is fixedly connected to the middle end of the lower side of the plug plate 31, and a top plate 34 is fixedly connected to the lower side of the push rod 33. In the process of squeezing the card plate 21, the first partition plate 2 simultaneously squeezes the second spring 32 with the assistance of the push rod 33 and the plug plate 31, and subsequently, the elastic potential energy of the second spring 32 pushes the sleeve 3 and the first partition plate 2 to cooperate with the first partition plate 2 to limit the position, so as to facilitate the restriction of the lower side of the first partition plate 2 and the subsequent assistance in the removal of the first partition plate 2.

[0025] like Figure 1 and Figure 2 As shown, the limiting assembly includes limiting plates 4 arranged on the upper sides of both ends of the first partition plate 2, and rubber pads 41 are fixedly connected to the upper sides of the limiting plates 4. When the first partition plate 2 moves downward, it is simultaneously limited by the limiting plates 4 and the rubber pads 41. The limiting plates 4 and the rubber pads 41 can be used to limit the downward movement distance of the first partition plate 2, so as to protect the placed negative electrode sheets.

[0026] like Figure 1 As shown, the dividing assembly includes a second dividing plate 51 inserted and fixedly connected inside the inner frame 5, and a third dividing plate 52 is passed through and fixedly connected to the outer side of the second dividing plate 51, the lower side of the inner frame 5 is fixedly connected to the upper side of the first dividing plate 2, and the lower side of the limiting plate 4 is fixedly connected to the upper sides of both ends of the inner frame 5, and the negative electrode sheets are placed one by one in the separation compartments of the second dividing plate 51 and the third dividing plate 52, so as to further restrict the negative electrode sheets by utilizing the space divided by the second dividing plate 51 and the third dividing plate 52.

[0027] Working principle: When the negative electrode sheets of lithium batteries need to be transported, the negative electrode sheets are first placed one by one in the compartments of the second partition plate 51 and the third partition plate 52 at the lower end of the outer frame 1. When the inner side of the inner frame 5 at the lower end of the outer frame 1 is placed, a set of first partition plates 2 drives the sleeve 3 and the like to be inserted into the outer frame 1. The first partition plate 2 first squeezes the upper card plate 21 so that the card plate 21 is inserted into the outer frame 1 under pressure to compress the first spring 22, and then continues to squeeze the lower card plate 21 so that the card plate 21 is inserted into the outer frame 1. When the first partition plate 2 is driven by the sleeve 3, etc., the lower side of the top plate 34 is in contact with the outer frame 1, and the first partition plate 2 is pressed against the second spring 32 with the assistance of the ejector rod 33 and the inserting plate 31. The first separator 2 is pressed, and then the sleeve 3 and the first separator 2 are pushed by the elastic potential energy of the second spring 32 to limit the lower side of the first separator 2 to cooperate with the first separator 2 to limit the position. When the first separator 2 moves downward, it is simultaneously limited by the limit plate 4 and the rubber pad 41. The limit plate 4 and the rubber pad 41 can be used to limit the downward movement distance of the first separator 2 to prevent the negative electrode sheet from being squeezed due to its excessive downward movement distance. Then, the above operation is performed, and the inner frame 5 inserted on the upper side of the first separator 2 in the outer frame 1 is filled with negative electrode sheets, and then Another set of first partition plates 2 drives the sleeve 3 and others to be inserted into the outer frame 1, so that they cooperate with the first partition plate 2 on the lower side to be locked. When removing and taking materials later, first press the card plates 21 on both sides. After the card plates 21 are squeezed, they are inserted into the outer frame 1 to compress the first spring 22. At this time, the second spring 32 simultaneously pushes the sleeve 3 and the first partition plate 2 upward with the assistance of the insert plate 31, the push rod 33 and the top plate 34, so that the first partition plate 2 and others pop out of the outer frame 1. The two sets of first partition plates 2 can be removed according to the above operations.

[0028] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
