DETAILED DESCRIPTION

[0032] Example 1:

[0033] Please refer to Figures 1-13 , the utility model provides a technical scheme: as Figures 1-2 Shown, a welding strip clamping device, including base plate 1 and installing on base plate 1 on drive structure 2.

[0034] The driving structure 2 comprises a driving member one 21, a driving member two 22 and a driving member three 23. The driving member three 23 is located between the driving member one 21 and the driving member two 22, and the driving end of the driving member three 23 is in active abutment with the driving end of the driving member one 21.

[0035] The driving structure 2 further comprises a sliding member one 6, a sliding member two 7, a clamping assembly one 41 and a clamping assembly two 42. The sliding member one 6 and the sliding member two 7 are in sliding connection with the side edges of the base plate 1.

[0036] The driving member one 21 comprises a cylinder one and a connecting rod assembly one 211. The cylinder one is fixedly connected to one end of the connecting rod assembly one 211. The other end of the connecting rod assembly one 211 is fixedly connected to one side of the sliding member one 6.

[0037] The driving member two 22 comprises a cylinder two and a connecting rod assembly two 221. The cylinder two is fixedly connected to one end of the connecting rod assembly two 221. The other end of the connecting rod assembly two 221 is fixedly connected to one side of the sliding member two 7.

[0038] The other side of the sliding member one 6 and the other side of the sliding member two 7 are respectively fixedly connected to the clamping assembly one 41 and the clamping assembly two 42, which are respectively used to drive the clamping assembly one 41 and the clamping assembly two 42 to move, so as to clamp or release the clamping of the welding strip.

[0039] As shown in Figures 2-6 The clamping assembly one 41 comprises a plurality of movable claws 411, a connecting plate 412 and a plurality of springs one 413. The side of the connecting plate 412 away from the sliding member one 6 is provided with a plurality of recesses one arranged at intervals. The movable claws 411 are rotationally connected to the side wall below the recess one and extend to the lower side of the connecting plate 412. The spring one 413 is arranged in each recess one. The two ends of the spring one 413 are respectively fixedly connected to the movable claw 411 and the side wall of the opposite side of the recess one.

[0040] The clamping assembly two 42 comprises a plurality of fixed claws 421 arranged at intervals with the movable claws 411. The top of the fixed claw 421 extends through the connecting plate 412 to the fixed connection with the protruding part provided on the side of the sliding member two 7. The fixed claw 421 is located below the connecting plate 412 and forms a clamping groove with the movable claw 411 for clamping the welding strip.

[0041] As shown in Figures 5-12 The sliding member one 6 comprises a plurality of sliding blocks one 61 and a sliding plate one 62. The sliding block one 61 is slidingly connected to the side edge of the base plate 1 along the length direction, and the sliding block one 61 is fixedly connected to the opposite side of the sliding plate one 62. The side wall of the sliding plate one 62 away from the sliding block one 61 is fixedly connected to the connecting plate 412. The upper side of the sliding plate one 62 extends toward the connecting rod assembly one 211 and is fixedly connected to the connecting rod assembly one 211.

[0042] The sliding piece two 7 comprises a sliding block two 71 and a sliding plate two 72; the sliding block two 71 is slidingly connected to the side of the base plate 1 along the length direction, and the sliding block two 71 is fixedly connected to the opposite side of the sliding plate two 72; the side wall of the sliding plate two 72 away from the sliding block two 71 is further protruded, and the protruded part of the sliding plate two 72 is fixedly connected with the fixed claw 421. The upper side of the sliding plate two 72 extends towards the direction of the linkage assembly two 221, and is fixedly connected with the linkage assembly two 221 (see Figure 6 and Figure 7 ). There is a distance between the sliding plate one 62 and the sliding plate two 72, so as to facilitate the sliding plate one 62 to drive the clamping assembly one 41 or the sliding plate two 72 to drive the clamping assembly two 42 to move. The sliding block one 61 and the sliding block two 71 are preferably two, and the sliding block one 61 and the sliding block two 71 can be the same structure for sliding.

[0043] As shown in Figure 13 , the upper middle part of the sliding plate one 62 protrudes a fixed block 312 towards one side of the driving piece three 23, and an elastic piece 5 is arranged between the fixed block 312 and the extended side of the sliding plate two 72, and the elastic piece 5 is preferably a spring two, and the two ends of the elastic piece 5 are fixedly connected with the extended side of the sliding plate two 72 towards the fixed block 312 and the fixed block 312 respectively.

[0044] Working principle: It should be noted that "right side" in the following means the direction towards the driving piece one 21, and "left side" means the direction towards the driving piece two 22.

[0045] The operator starts the driving piece one 21 and the driving piece two 22. The driving ends of the driving piece one 21 and the driving piece two 22 drive the linkage assembly one 211 and the linkage assembly two 221 to move towards each other.

[0046] That is, the connecting rod assembly two 221 drives the slider two 71, the slide plate two 72 and the fixed claw 421 to move; the connecting rod assembly one 211 drives the slider one 61, the slide plate one 62, the connecting plate 412, the spring one 413 and the movable claw 411 to move. In this way, the welding strip is clamped by the opposite movement of the movable claw 411 and the fixed claw 421, and the welding strip is pulled out. When reaching the position above the battery piece where the welding strip needs to be placed, the driving part one 21 and the driving part two 22 are in the state of no force output and no action under the control of the intermediate relief type battery valve (this is a conventional technical means, which will not be described in detail here), the driving end of the driving part three 23 moves to the direction of the driving part one 21 on the right side, and pushes the driving end of the driving part one 21 on the right side to move. The driving end of the driving part one 21 on the right side drives the connecting rod assembly one 211 and the corresponding movable claw 411 to move away from the left connecting rod assembly two 22, thereby increasing the distance between the movable claw 411 and the fixed claw 421, so as to open the clamping of the welding strip for the first time. When the welding tool is pressed to press the welding strip on the battery piece to prepare for welding, the clamping position of the welding strip is adjusted, so as to realize the accurate control of the welding strip. When welding, if the width of the welding strip deviates, the lower end of the movable claw 411 will be pushed to rotate away from the welding strip, so that the upper end of the movable claw 411 rotates towards the spring one 413. At the same time, the spring one 413 will exert a counter force on the upper end of the movable claw 411, so that the lower end of the movable claw 411 rotates towards the welding strip, so as to keep the clamping state of the welding strip at all times, avoiding the problem of deviation when clamping the welding strip for welding.

[0047] Then the driving ends of the driving part one 21 and the driving part two 22 drive the connecting rod assembly one 211 and the connecting rod assembly two 221 and the corresponding movable claw 411 and the fixed claw 421 to move reversely. The movable claw 411 and the fixed claw 421 are opened, so as to be opened for the second time, preparing for the next clamping. The driving part three 23 moves reversely, restoring the state of the driving end of the driving part three 23 when it is not pushed.
