Description

Technical Field

[0001] This utility model relates to the field of lithium battery soft pack assembly technology, specifically to an upper pressure plate mounting device for lithium battery pack assembly. Background Technology

[0002] In lithium battery pack assembly, the installation of the upper plate usually refers to the operation of installing a metal or non-metal plate that serves to fix, support or protect the battery module or battery pack structure. Its core function is to ensure the stability, safety and structural integrity of the battery module within the battery pack.

[0003] In the current assembly of lithium battery pouch cells, the assembled battery pack is placed inside the packaging box, and then the structure is sealed by installing a pressure cap to provide protection. During installation, one person needs to hold the box in place while another person lifts the battery pack, places it inside the box, connects the battery pack to the pressure cap, and finally places the pressure cap on top of the box and tightens it with hex bolts. This installation method is relatively labor-intensive and physically demanding, and has low installation efficiency. Utility Model Content

[0004] The technical problem this utility model aims to solve is that the existing lithium battery soft pack assembly requires two people to work together: one person to fix the box and the other to move the battery pack into the box, connect the wires, and then put on the cover and tighten it with hex bolts. This method is labor-intensive and has low installation efficiency.

[0005] To solve the above problems, the technical solution adopted by this utility model is an upper pressure plate mounting device for lithium battery pack assembly, including a frame structure, which includes a high frame and a low frame. A conveyor belt structure is provided at the top of the low frame. A placement frame is provided on the inner side of the middle of the high frame. Gear 1 is fixed on both sides of the placement frame and is rotatably connected to the inner side of the high frame. A drive shaft is rotatably provided on the inner side of the high frame. Gear 2, which meshes with gear 1, is fixed on the side of the drive shaft. Telescopic top rods electrically connected to an external power source are rotatably provided on both sides of the placement frame. The bottom end of the telescopic top rod is hinged to the bottom end of the frame structure. A telescopic rod electrically connected to an external power source is fixed at the top of the high frame. A cross connecting plate is fixed at the bottom end of the telescopic rod. A connecting frame is fixed on the side of the cross connecting plate outside the high frame. A support plate is fixed on the side of the connecting frame. A telescopic short rod electrically connected to an external power source is fixed on the upper side of the support plate. An electric screwdriver electrically connected to an external power source is fixed at one end of the telescopic short rod. An opening is provided on the side of the connecting frame at the electric screwdriver.

[0006] As a further embodiment of this utility model: a support platform is fixed in the middle of the elevated structure to provide auxiliary support for the placement frame.

[0007] As a further embodiment of this utility model: a motor 1, electrically connected to an external power source, is fixed on one end of the transmission shaft on the elevated side to drive the transmission shaft to rotate; a motor 2, electrically connected to an external power source, is fixed on one side of the conveyor belt structure to drive the conveyor belt structure to operate.

[0008] As a further embodiment of this utility model: a workbench is provided on one side of the frame structure above the conveyor belt structure for assembling lithium battery pouches.

[0009] As a further embodiment of this utility model: a lithium battery pack protective frame is placed in the placement frame, and the height of the bottom inner side of the placement frame is the same as the height of the upper side of the conveyor belt structure, which facilitates the conveying of the assembled lithium battery pack from the conveyor belt structure into the lithium battery pack protective frame in the placement frame.

[0010] As a further embodiment of this utility model: the width of the placement frame is greater than the width of the elevated frame, and the top of the telescopic top rod is located at one end of the side of the placement frame to prevent the elevated frame from obstructing the top of the telescopic top rod.

[0011] Compared with the prior art, the advantages of this utility model are as follows: This application adds a conveyor belt structure and a placement frame structure, which can adjust the angle through gear transmission and telescopic top rod, so as to transport the assembled battery pack into the lithium battery pack protective frame inside the placement frame. The placement frame is erected through telescopic top rod and gear transmission, and then the connecting frame is moved down through the telescopic rod and fixed with screws by electric screwdriver, which saves manpower and time and improves work efficiency.
