Abstract
Description
Technical Field
[0001] The utility model relates to a welding positioning device for a pole ear and a lead piece used in the production of a lithium ion battery, belonging to the technical field of battery production. Background Art
[0002] In the production process of lithium-ion batteries, the assembly process is a crucial link, which involves the welding of the positive and negative leads of the upper cover with the positive and negative tabs of the battery cell. In addition, the QR code scanning process of the battery cell and the upper cover is also a key step to ensure product quality and track product information.
[0003] However, in the existing lithium-ion battery production and assembly process, the positive electrode tab welding, negative electrode tab welding and code scanning operations rely on three workers to complete manually. This method has the following defects:
[0004] 1. During the welding process, workers need to hold the battery cells and the upper cover by hand to ensure the accuracy of welding. This operation is not only labor-intensive, but also difficult to ensure accuracy.
[0005] 2. Since each battery cell requires manual operation, a large number of workers are required to participate, which not only increases personnel costs but also reduces production efficiency.
[0006] 3. Long working hours can easily lead to worker fatigue, which may lead to poor welding positions and even the risk of short circuits caused by the negative lead connecting to the shell. In addition, fatigue operation may also cause the lead to press on the battery cell, increasing the risk of thermal runaway during battery use.
[0007] 4. Due to different operating habits and skill levels of each person, there are differences in welding positions, which affects the overall quality and consistency of the product. Utility Model Content
[0008] In order to solve the problems existing in the background technology, the utility model provides a welding positioning device for a tab and a lead piece used in the production of a lithium-ion battery.
[0009] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a device for welding and positioning a tab and a lead for lithium-ion battery production, comprising a connecting rod, a battery cell positioning mechanism and an upper cover positioning mechanism, wherein the battery cell positioning mechanism comprises a battery cell placement platform and a battery cell positioning block; the upper cover positioning mechanism comprises an upper cover pole positioning block, an upper cover placement platform, an upper cover support frame, an upper cover positioning groove and an upper cover retaining frame positioning block; a battery cell positioning block and a positioning groove are provided at the upper end of the battery cell placement platform; an upper cover placement platform is fixedly provided at the upper end of the upper cover support frame, and an upper cover pole positioning block, an upper cover positioning groove and an upper cover retaining frame positioning block are provided at the upper end of the upper cover placement platform; the upper cover support frame is fixedly connected to the battery cell placement platform by a connecting rod.
[0010] The battery core placement platform is slidably connected to the bottom plate.
[0011] A battery cell code scanning gun connection block is fixed at the upper end of the battery cell placement platform, and a battery cell code scanning gun is fixed on the battery cell code scanning gun connection block.
[0012] An upper cover code scanning gun connecting block is fixed to the upper end of the upper cover supporting frame, and an upper cover code scanning gun is fixed on the upper cover code scanning gun connecting block.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. The utility model ensures that the distance between the tab and the lead is the same, ensures the consistency of the product, thereby ensuring the stability of the bending, and avoids the instability of the size of manual hand-held welding, making the operation more convenient and safe. At the same time, it avoids the risk of poor welding position due to fatigue of the operator, short circuit caused by the lead connecting to the shell, and the lead pressing the battery cell, thus ensuring the stability and safety of the battery.
[0015] 2. The utility model simultaneously inputs QR code information during the welding process, and only one person is required to perform welding and code scanning, which reduces the number of personnel operations and saves production costs. BRIEF DESCRIPTION OF THE DRAWINGS
