Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery assembly, in particular to a lithium battery assembly rack which is convenient for batch processing. Background Art

[0002] Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metallic lithium and are rechargeable. The fifth generation of rechargeable batteries, lithium metal batteries, was born in 1996. Their safety, specific capacity, self-discharge rate and performance-price ratio are better than lithium ion batteries. Due to its own high technical requirements, only companies in a few countries are producing this type of lithium metal battery. When the total number of cells in a lithium battery pack is relatively large, the addition of a cell bracket is more for the stability of the lithium battery pack structure.

[0003] For example, an assembly rack for lithium battery assembly with application number CN202121601295.X includes a main shell and a bracket, wherein the main shell is fixed above the bracket, a plurality of transverse baffles are fixed at intervals in the main shell, a plurality of vertical baffles are fixed at intervals in the main shell, and the plurality of vertical baffles and the plurality of transverse baffles are arranged crosswise with each other, lithium battery cells are placed between the plurality of vertical baffles and the plurality of transverse baffles, a bottom plate is placed at the bottom of the battery cells, side sliding holes are opened under the plurality of vertical baffles and the plurality of transverse baffles, a connecting rod is fixed between the two bottom plates, and the connecting rod is slidably arranged in the side sliding hole, the assembly rack stores a plurality of lithium battery cells through the main shell, and the wheels can facilitate the movement of the bracket. However, the lithium battery assembly rack requires manual hand-held welding heads for welding, which makes it difficult to control the welding strength, and there are many nickel sheets arranged at the intersection of the transverse plate fixing block and the vertical plate fixing block, which may be missed during welding, the welding precision is not high, and harmful gases are generated during welding, which may cause harm to the human body. Therefore, in view of this, the existing structural deficiencies are studied and improved, and a lithium battery assembly rack that is convenient for batch processing is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a lithium battery assembly rack that is convenient for batch processing, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lithium battery assembly rack that is convenient for batch processing, comprising a mounting frame and a cooling fan, a groove is opened on one side of the mounting frame, and a cooling fan is fixedly connected to the inside of the groove, a dustproof net is fixedly connected to one side of the cooling fan, and a bracket is fixedly connected to the bottom of the mounting frame, and a driving mechanism is fixedly connected to the top of the mounting frame.

[0006] Preferably, the driving mechanism includes a fixing frame fixedly connected to the top position of the mounting frame, and a servo motor is fixedly connected to one side of the fixing frame, a driving rod is fixedly connected to one side of the servo motor, and a moving block is connected to the external thread of the driving rod.

[0007] Preferably, a return spring is fixedly connected to the interior of the mounting frame, and a baffle is fixedly connected to one end of the return spring.

[0008] Preferably, a limiting frame is movably connected to the bottom of the baffle, and the lithium battery body is fixed inside the limiting frame.

[0009] Preferably, one end of the lithium battery body is fixedly connected to a positioning mechanism, and the positioning mechanism includes a horizontal plate fixing plate fixedly connected to one side of the lithium battery body, and one side of the horizontal plate fixing plate is fixedly connected to a vertical plate fixing plate, and a nickel plate is fixedly connected at the intersection of the horizontal plate fixing plate and the vertical plate fixing plate.

[0010] Preferably, one side of the lithium battery body is fixedly connected with silicone rubber, and the bottom of the moving block is fixedly connected with an electric lifting rod, and one end of the electric lifting rod is provided with a welding head.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model is provided with a driving mechanism and a positioning mechanism. The servo motor inside the driving mechanism drives the driving rod to rotate at a certain frequency. When the welding head is consistent with the center line of the nickel sheet, the moving block automatically stops moving outside the driving rod, and the welding head welds and fixes the nickel sheet and the lithium battery body. The traditional assembly frame requires manual hand-held welding heads for welding, which is difficult to control the welding force. In addition, there are many nickel sheets arranged at the intersection of the horizontal plate fixing block and the vertical plate fixing block, which may be missed during welding. The welding precision is not high, and harmful gases are generated during welding, which will cause harm to the human body. The driving rod inside the driving mechanism provided by the utility model can drive the welding head at the bottom of the moving plate to perform batch welding processing, which can improve the welding degree and improve the processing efficiency and reduce the labor input cost. At the same time, a positioning mechanism is provided on one side of the lithium battery body. After fixing each string of lithium batteries, the nickel sheet insulating material inside the positioning mechanism is used to separate each string of lithium batteries to prevent the outer skin of the lithium battery body from being damaged and causing a short circuit in the future.

[0013] 2. The utility model provides a limiting frame and silicone rubber. When assembling the outer skin of the lithium battery body, the limiting frame serves as a container for fixing the lithium battery body to prevent the lithium battery pack from changing when it is moved after being arranged. The silicone rubber isolates the lithium battery body, and every two lithium batteries are bonded together with adhesives such as silicone rubber, thereby achieving a better fixing effect.
