Description

TECHNICAL FIELD

[0001] The application relates to the technical field of lithium batteries, and particularly relates to a lithium battery module clamping jig. BACKGROUND

[0002] Lithium batteries are a kind of batteries using non-aqueous electrolyte solution with lithium metal or lithium alloy as positive / negative electrode material. Due to the very active chemical properties of lithium metal, the processing, preservation and use of lithium metal have very high requirements on the environment. With the development of science and technology, lithium batteries have become mainstream. 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 safety, specific capacity, self-discharge rate and performance-price ratio of rechargeable batteries are superior to those of lithium ion batteries.

[0003] Lithium batteries are various, and a lithium battery module is assembled by a plurality of lithium batteries. A clamping jig needs to be used during production of the lithium battery module. A lithium battery module auxiliary welding jig is disclosed in Chinese Patent No. CN108274174A, which comprises a side plate, an upper cover plate, a carrier, a bottom plate, a magnetic component, a magnetic plate, a hinge, and an observation hole. The carrier of the lithium battery module auxiliary welding jig can well cooperate with the slide of a spot welding machine, and can be conveniently pressed and fixed. The battery module product to be welded can be well fixed, and shifting and inaccurate positioning can be avoided. The present application has the functions of battery pack guiding, fixing and limiting, and can be well matched with the spot welding machine through the bottom plate, facilitating installation and replacement in the machine, reducing manual operation, improving production capacity and efficiency, ensuring the simplicity and accuracy of the process, ensuring the welding quality, facilitating processing and manufacturing, and having high practicality and low cost.

[0004] Chinese Patent No. CN213580385U discloses a lithium battery module welding quality test jig, which comprises a base, a support plate fixedly installed on one side of the base, a bottom plate fixedly installed on one side of the support plate, a clamp fixedly installed on one side of the bottom plate, a motor box fixedly installed on one side of the clamp, a lead screw fixedly installed on one side of the motor box, and a switch fixedly installed on one side of the lead screw. The lithium battery module welding quality test jig can test the tension of welding spots at different angles, so that the test result is more accurate. The first clamping plate and the second clamping plate are used to clamp the lithium battery module, so as to avoid the problem that the lithium battery module falls onto the test table and is damaged. The lithium battery module welding quality test jig has high accuracy and low loss.

[0005] A lithium battery module welding jig is disclosed in Chinese patent CN110788529A, which comprises a jig left side baffle, a jig right side baffle, a jig bottom plate, a jig welding side plate, a jig clamping cylinder, a jig left side clamping assembly and a jig right side clamping assembly. The jig left side clamping assembly comprises a jig left side vertical plate, a clamping plate and a clamping connecting rod. The clamping plate is in the shape of a "bow", and the middle part of the clamping plate is arranged at the top middle position of the jig left side vertical plate. The clamping connecting rod has two ends, the lower end of the clamping connecting rod is hinged to the jig left side baffle, and the upper end of the clamping connecting rod is hinged to the groove of the "bow" shaped left clamping plate. The structure of the jig right side clamping assembly is the same as that of the jig left side clamping assembly. The advantage of this patent is that the jig clamping cylinder lifts the jig clamping lifting plate upward, so that the upper clamping elements of the jig left side baffle and the jig right side baffle clamp the lithium battery module, ensuring the reliability of clamping.

[0006] However, this three patents are convenient to install and replace in the machine table, also improve the accuracy of the jig, and ensure the reliability of clamping, but cannot automatically clamp, resulting in the need for manual clamping by the user when using, and cannot automatically clamp, thereby increasing the labor of the user.
