[0048] Working principle:

[0049] The first cylinder 121 drives the jaw lever module 125 to reciprocate in the horizontal direction through the transmission rod 122 and the cylinder driving module 124; the reciprocating linear motion of the transmission rod 122 is converted into the reciprocating swing of the jaw lever module 125, and the reciprocating swing of the jaw lever module 125 drives the jaw assembly to clamp and release the welding strip, and the transmission rod 122 and the jaw lever module 125 realize the amplification effect of the output torque of the cylinder.

[0050] The first cylinder is higher than the overall height requirement of the new welding strip clamping mechanism, in order to avoid other mechanisms of the equipment, the first cylinder is placed at the end of the support assembly, and the span from the end to the jaw lever module is large, so that the effect is achieved with the smallest force;

[0051] The linear bearing arranged on the transmission rod 122 ensures that the transmission rod 122 can accurately realize linear reciprocating motion;

[0052] The jaw assembly contacts the jaw lever through the bearing contact block, and since there is rolling friction between the two, the bearing contact block is adopted to avoid the wear of the overall fixed jaw and the overall movable jaw assembly plate caused by friction. When the bearing contact block is seriously worn, it only needs to be replaced, which is simple to operate and low in cost. The overall fixed jaw and the overall movable jaw assembly plate are installed on the linear guide rail, and the swing of the lever is converted into the opening and closing of the overall fixed jaw and the overall movable jaw assembly plate, so as to realize the clamping and releasing of the welding strip.

[0053] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this; any person skilled in the art can make equivalent replacement or change according to the technical range disclosed in the present application and the improved concept of the technical solution of the present application, which should be covered in the protection scope of the present application.
