[0002] In the field of solder protection technology, numerous problems are often encountered when soldering battery cells. Existing technologies, some solder protection fixtures have significant shortcomings in their protective performance. Solder beads are easily splattered during the soldering process, which can damage the battery cells, seriously affect operational safety, and may even lead to process defects.

[0003] Moreover, existing fixtures are not precise enough in positioning the battery cells, which makes the cells prone to shaking during the soldering process, resulting in offset soldering positions and greatly increasing the soldering defect rate. At the same time, most fixtures are difficult to adapt to the fixing requirements of battery cells of different sizes. When dealing with battery cells of different specifications, it is necessary to frequently change the fixture, which not only wastes time but also reduces production efficiency. Therefore, it is necessary to design a solder protection fixture to solve the above problems. Utility Model Content

[0013] Compared with the prior art, this utility model provides a solder protection fixture, which has the following beneficial effects:

[0014] 1. This soldering protective fixture provides reliable protection for the battery cell through its protective mechanism. The combination of the protective platform and cover plate effectively prevents solder balls from splashing during soldering operations, avoiding damage to the battery cell and greatly improving operational safety. It also reduces process defects caused by high-temperature soldering. At the same time, the mounting slot inside the protective platform provides precise positioning for the battery cell, ensuring that the battery cell does not move around during soldering, guaranteeing the accuracy of the soldering position, and reducing the soldering defect rate caused by positional deviation. The coordinated design of the adjusting shaft, moving frame, and clamping plate allows the fixture to adapt to the fixing requirements of battery cells of different sizes. By rotating the adjusting shaft, the moving frame moves back and forth, thereby adjusting the position of the clamping plate to achieve stable clamping of the battery cell. This not only improves the versatility of the fixture but also allows for quick adjustment according to the specifications of different battery cells, effectively improving production efficiency and reducing time losses caused by changing fixtures. Furthermore, the tabs on the front side of the battery cell can be placed in the fixing slot on the top of the protective platform to ensure the stability of the tabs.

[0029] Please see Figure 1-7 The present invention provides a technical solution: a solder protective fixture, including a base 1, a protective mechanism 2 on the top of the base 1, and a heat dissipation mechanism 3 on the front side of the protective mechanism 2;

[0030] The protective mechanism 2 includes a protective platform 21, which is fixedly connected to the top of the base 1. Fixed rods 22 are fixedly connected to the left and right sides of the protective platform 21. A cover plate 23 is rotatably connected to the periphery of the fixed rods 22. A battery cell 24 is slidably connected inside the protective platform 21. A tab 25 is fixedly connected to the front and rear sides of the battery cell 24. The tab 25 is located on the top of the protective platform 21. A connecting rod 26 is slidably connected inside the protective platform 21. A clamping plate 291 is fixedly connected to the front side of the connecting rod 26. The clamping plate 291 is slidably connected inside the protective platform 21. A movable frame 27 is fixedly connected to the rear side of the connecting rod 26. An adjusting shaft 28 is threadedly connected inside the movable frame 27. A support frame 29 is rotatably connected to the periphery of the adjusting shaft 28.

[0031] The protective platform 21 has an installation slot inside, the battery cell 24 is slidably connected in the installation slot, and the clamping plate 291 is slidably connected in the installation slot, so as to facilitate the placement of the battery cell 24 through the installation slot.

[0032] A fixing groove is provided on the front side of the top of the protective platform 21. The top of the inner side of the front and rear tabs 25 of the battery cell 24 is in contact with the top of the protective platform 21, and the front tab 25 of the battery cell 24 is slidably connected in the fixing groove, so as to ensure the stability of the tab 25 through the fixing groove.

[0033] The support frame 29 is fixedly connected to the top rear side of the base 1, and the bottom of the movable frame 27 is slidably connected to the top of the base 1, so that the connecting rod 26 and the clamping plate 291 can be moved by the movable frame 27.

[0034] Example 2

[0035] Please see Figure 1-7Furthermore, based on Embodiment 1, the heat dissipation mechanism 3 includes a mounting frame 31, which is fixedly connected to the bottom front side of the protective platform 21. A fan 32 is fixedly connected inside the mounting frame 31, and a guide frame 33 is fixedly connected to the top of the mounting frame 31.

[0036] The mounting frame 31 has a rectangular slot inside, and the fan 32 is fixedly connected in the rectangular slot, which makes it easy to install the fan 32 through the rectangular slot. The top of the air guide frame 33 has an air outlet, and the air outlet is located on the rear side of the top of the air guide frame 33. This makes it easy to ensure that the solder falling during the soldering process will not affect the fan 32 by setting the air outlet on the rear side of the top of the air guide frame 33.

[0037] In actual operation, when this device is used and welding of the battery cell 24 with other metal components is required, firstly, the tabs 25 on both the front and rear sides of the battery cell 24 are cut to the specified size, and then the battery cell 24 is slidably connected to the mounting groove inside the protective platform 21, so that the inner top of the tabs 25 on both the front and rear sides of the battery cell 24 is in contact with the top of the protective platform 21, and the front tab 25 of the battery cell 24 is slidably connected to the fixing groove on the top of the protective platform 21.
