The principles of the present invention will be illustrated through embodiments, and other aspects, features, and advantages of the present invention will become apparent from this detailed description. In the accompanying drawings, the same or similar parts in different figures are indicated by the same reference numerals.
[0023] Example 1
[0024] like Figures 1-2 As shown, this utility model provides a welding clamp structure for battery welding. The welding clamp structure includes clamps 1 and welding clamps 2, with the welding clamps 2 connected to the front end of clamps 1. Clamps 1 includes a first clamp arm 11, a second clamp arm 12, and a rotating shaft 13. The rear end of the first clamp arm 11 intersects with the rear end of the second clamp arm 12. The rotating shaft 13 is installed at the intersection of the first clamp arm 11 and the second clamp arm 12 to achieve a rotatable connection between the first clamp arm 11 and the second clamp arm 12. In a specific implementation, clamps 1 also includes a first handle 14 and a second handle 15. The first handle 14 is hinged to the second handle 15 through the rotating shaft 13. The first handle 14 and the second handle 15 are separated by the rotating shaft 13. The operator controls the opening or closing of the first clamp arm 11 and the second clamp arm 12 by holding the first handle 14 and the second handle 15. The welding clamp 2 includes a first welding clamp head 21, a second welding clamp head 22, two guide shafts 23, and a push slider 24. The first welding clamp head 21 and the second welding clamp head 22 are arranged opposite to each other and fixed to the front ends of the first clamp arm 11 and the second clamp arm 12. The two guide shafts 23 are distributed parallel to each other and pass through the first welding clamp head 21 and the second welding clamp head 22. The push slider 24 is located at the upper end of the first welding clamp head 21 and fixed to the front end of the first clamp arm 11. A slider fixing shaft 25 is fixed on the first welding clamp head 21. The push slider 24 is provided with a sliding groove 241 that cooperates with the slider fixing shaft 25. The slider fixing shaft 25 on the first welding clamp head 21 can slide along the sliding groove of the push slider 24.
[0025] The first welding clamp head 21 and the second welding clamp head 22 designed in this utility model are mainly used for welding two butt welds of adjacent electrode groups inside a storage battery. By controlling the opening of the first clamp arm 11 and the second clamp arm 12 on the clamp 1, the first clamp arm 11 drives the first welding clamp head 21 and the upper push slider 24 to open outward during the opening process, so as to realize the opening of the first welding clamp head 21 and the second welding clamp head 22, which facilitates the first welding clamp head 21 and the second welding clamp head 22 to remove the film from the welding point of the two butt welds of the adjacent electrode groups. The slider fixing shaft 25 is set to be locked in the sliding groove 24 of the push slider 24. Within 1, the direction of movement of the push slider 24 is ensured, and the first welding clamp head 21 under the push slider 24 is driven to freely separate and close. By setting two guide shafts 23, it can be ensured that the first welding clamp head 21 and the second welding clamp head 22 can separate along a horizontal straight line. The push slider 24, the slider fixing shaft 25, and the guide shaft 23 play an auxiliary role in controlling the separation of the first welding clamp head 21 and the second welding clamp head 22 by the push slider 24, so that the first welding clamp head 21 and the second welding clamp head 22 of the welding clamp 2 can be easily disengaged from the welding part after welding, thus improving the convenience of operation for the staff.
[0026] like Figures 3-4 As shown in the embodiment of this utility model, the first welding clamp head 21 includes a first welding semicircular hole 211 and a first baffle 212. The first baffle 212 surrounds the outside of the first welding semicircular hole 211. The second welding clamp head 22 includes a second welding semicircular hole 221 and a second baffle 222. The second baffle 222 surrounds the outside of the second welding semicircular hole 221. The first welding semicircular hole 211 of the first welding clamp head 21 and the second welding semicircular hole 221 of the second welding clamp head 22 form a welding groove. During welding, the first welding semicircular hole 211 of the first welding clamp head 21 and the second welding semicircular hole 221 of the second welding clamp head 22 are used to clamp the two welding parts of the pole group. The flame sprayed by the welding gun is used to heat and melt the welding ends of the two welding parts, so that the welding ends of the two welding parts are fused together. When the welding ends of the two welding parts are heated and melted at high temperature, sparks will be generated. The first baffle 212 provided on the first welding clamp head 21 and the second baffle 222 provided on the second welding clamp head 22 can effectively wrap the sparks generated during welding, and prevent the welding flame from leaking out too much and burning the adjacent parts of the two welding parts.
[0027] In this embodiment, the first welding semicircular hole 211 of the first welding clamp head 21 and the second welding semicircular hole 221 of the second welding clamp head 22 clamp the welding ends of the two welding parts of the electrode group. The welding ends of the two welding parts are heated by gas welding or the flame of a welding gun, so that the welding ends of the two welding parts are fused together to achieve the welding purpose. The first baffle 212 and the second baffle 222 can effectively prevent the sparks generated by welding from burning other components of the battery, such as the battery separator wall, thereby improving the production quality of the battery.
[0028] The first welding tongs head 21 comprises a first fire blocking strip 213, and the first fire blocking strip 213 is fixed at the middle lower end of the first butt welding semicircular hole 211; the second welding tongs head 22 comprises a second fire blocking strip 223, and the second fire blocking strip 223 is fixed at the middle lower end of the second butt welding semicircular hole 221. By arranging the first fire blocking strip 213 at the middle lower end of the first butt welding semicircular hole 211 and the second fire blocking strip 223 at the middle lower end of the second butt welding semicircular hole 221, when the welding ends of two butt welding pieces are welded and melted, the boss of the two butt welding pieces will not be burnt through, the thickness of the welding surface can be ensured, the lead liquid can be blocked from dropping, the phenomenon of virtual welding and lead leakage can be avoided, the lead liquid can be prevented from leaking to the pole group to cause the battery short circuit, and the battery can be prevented from being scrapped.
[0029] The above has made a detailed description of the utility model, and the above is only a preferred embodiment of the utility model, and cannot limit the scope of the application, that is, all equivalent changes and modifications made according to the scope of the application should still be within the scope of the utility model.
