Description

Technical Field

[0001] The utility model application relates to the technical field of cleaning frames, in particular to a cleaning frame for a square lithium battery top cover sheet. Background Art

[0002] Lithium batteries generally use manganese dioxide as the positive electrode material, metallic lithium or its alloy metal as the negative electrode material, and use non-aqueous electrolyte solutions. According to different battery packaging technology routes, there are mainly three shapes: square, cylindrical, and soft pack. The cylindrical and square are collectively called hard shells. The packaging structure is relatively similar, both consisting of a shell and a cover. The battery top cover needs to be fixed in a cleaning frame for cleaning after it becomes dirty.

[0003] The cleaning frames for placing products in the automatic cleaning equipment currently used in the market adopt a one-to-one mode. Different cleaning frames are adapted according to the length, width and height of the top cover piece. There are many types of top cover pieces, so there are also cleaning frames of various sizes. Most of the cleaning frames on the market are injection molded in one process. If the size needs to be changed after the batch production of the cleaning frames is completed, processing costs will be incurred. The total processing cost is high, and it is easy to lead to a large number of cleaning frames, which occupy a large space. Summary of the invention

[0004] In order to solve the problem that the existing square lithium battery top cover sheet cleaning frame cannot be used for top cover sheets of different sizes when in use, the utility model provides a square lithium battery top cover sheet cleaning frame to solve the above problem.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] Furthermore, both ends of each of the beams 1 are fixed to the beam 3 by bolts, the beam 1 is located directly above the single-sided product limit block, and the length of the beam 1 is less than the length of the single-sided product limit block.

[0009] Furthermore, each of the beam three, beam four, beam five, single-sided product limit block, double-sided product limit block and floating limit block is provided with a socket that cooperates with the fixing screw, and the outer ring of each fixing nut is directly larger than the diameter of the socket.

[0010] Furthermore, a plurality of cross beams 2 are equidistantly arranged between the two cross beams 4, U-shaped grooves are symmetrically opened inside the two cross beams 4, and another fixing screw is inserted inside the U-shaped groove, and each other fixing screw is inserted into the U-shaped groove and threadedly fixed inside the cross beam 2.

The outer ends of each cross beam 2 6 and the floating limit block 14 are slidably inserted in the supporting groove 15. The thickness of each cross beam 2 6 is equal to the thickness of the floating limit block 14. A cross beam 5 10 is provided at the ends between the two cross beams 4 8. A number of fixing screws 3 are equidistantly inserted in each group of upper and lower cross beams 3 7 and cross beams 4 8.
