[0020] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0021] Please refer to Figures 1 to 3 As shown, the utility model is a lithium battery cover plate pole welding proofing tool, comprising a welding tool base plate 1 and a pressing block 2; a positioning groove 11 is provided on the plate surface of the welding tool base plate 1, and a limit block 12 arranged around the positioning groove 11 is provided on the welding tool base plate 1;

[0022] The pressing block 2 is detachably arranged on the top of the limiting block 12 , and the pressing block 2 is pressed on the pole area of ​​the lithium battery cover plate 3 . A through hole 21 is arranged on the pressing block 2 , and the through hole 21 exposes the pole of the lithium battery cover plate 3 .

[0023] Working principle: During the sample preparation process, the lithium battery cover plate 3 and related pole welding parts are assembled in sequence and placed in the positioning groove 11 of the welding tooling base plate 1, and then the pressing block 2 is connected to the limit block 12, so that the pressing block 2 can be properly pressed on the pole area of ​​the lithium battery cover plate 3, and at the same time, the pole of the lithium battery cover plate 3 is exposed by the through hole 21, so that the welding equipment can weld the pole to the lithium battery cover plate 3 through the through hole 21.

[0024] In one embodiment, see Figure 3 As shown, the pressing block 2 is provided with a plurality of exhaust channels 22 connected to the through holes 21, and the pressing block 2 is provided with a gas joint 23 connected to the exhaust channel 22. The gas joint 23 is connected to a vacuum cleaner and other related exhaust equipment, so that the welding smoke generated by the welding pole can be discharged from the exhaust channel 22 in time, preventing explosion points from occurring during the welding process, and reducing the pollution of the surface of the lithium battery cover 3 by the welding smoke.

[0025] In an optional embodiment, the through hole 21 is truncated cone-shaped, and the small diameter end of the through hole 21 is close to the lithium battery cover. The truncated cone-shaped through hole 21 helps the welding smoke to diffuse, so that it can be sucked away from the exhaust channel 22 by related exhaust equipment such as a vacuum cleaner.

[0026] In one embodiment, see Figure 3 As shown, the pressing block 2 is provided with a thermocouple thermometer temperature sensing wire 24, and the detection end of the thermocouple thermometer temperature sensing wire 24 is close to the through hole 21. Among them, the detection end of the thermocouple thermometer temperature sensing wire 24 is preferably not only close to the through hole 21, but also close to the pole welding area of ​​the lithium battery cover 3. The thermocouple thermometer temperature sensing wire 24 can detect the temperature in real time during the welding process, which is conducive to data control and diversified data collection during the proofing process.

[0027] In an optional embodiment, the limit block 12 is connected to the pressing block 2 by screws. Since this solution belongs to the proofing tooling, compared with using a cylinder or electric cylinder to operate the pressing block 2 to press and fix the lithium battery cover plate 3, the use cost of screw locking is lower. At the same time, the screw locking method has stronger fixation than the quick clamp and can ensure the compression of the sealing ring on the lithium battery cover plate 3.

[0028] In one embodiment, see Figure 1 and Figure 2 As shown, the top of the limit block 12 is provided with baffles 121 against both sides of the pressing block 2. The limit block 12 uses the baffles 121 to limit the pressing position of the pressing block 2 on the lithium battery cover 3 to avoid poor welding of the pole due to biased pressing.

[0029] In one embodiment, see Figure 2As shown, the welding tool base plate 1 is provided with a guide block 13 arranged around the positioning groove 11, and the top of the guide block 13 is provided with a chamfer inclined toward the positioning groove 11. The guide block 13 can be used to guide the lithium battery cover plate 3 to be placed in the positioning groove 11.

[0030] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
