[0057] The first separation block 225 is provided with a sliding connection hole 2253 extending along the second direction, and the cross support plate 211 is provided with a sliding connection column on the inner wall of the first sliding hole.

The two positioning clamps are slidably arranged on the cross support plate 211 of the positioning seat 21 along the first direction, and the two positioning clamps can approach each other under the elastic force of the second elastic member 231 to clamp and position the contact 102, so that the position of the contact 102 on the contact blade 101 meets the set requirements. The two second separation components can also respectively drive the two positioning clamps away from each other, so that other operations such as welding or cutting can be performed after the contact 102 is placed on the end of the contact blade 101.

When the second separation block 234 loses the upward force along the second direction, the second elastic members 231 on both sides respectively drive the two positioning blocks 232 to approach each other.

[0066] It should be noted that the structure of the second separation block 234 is the same as that of the first separation block 225 , and the detailed structure of the second separation block 234 will not be repeatedly described here.

The first driving member 51 can drive the first pushing plate 52 to move upward along the second direction, so that the first pushing plate 52 drives the second separation block 234 to move upward, so that the two positioning blocks 232 in the contact positioning assembly 23 move away from the contact knife 101, and when the first pushing plate 52 moves upward, the pushing block 53 abuts against the first separation block 225, so that the first separation block 225 drives the sliding clamping block 222 to move away from the contact knife 101. By setting the first driving assembly 5, the operation is more convenient and the production efficiency is further improved.

[0069] Optionally, a second driving assembly 6 is provided at both the contact loading station 15 and the welding station 17, and the second driving assembly 6 includes a second driving member 61 and a second pushing plate 62. The second driving member 61 is fixedly provided on the platform 3, and the second pushing plate 62 is fixedly provided at the output end of the second driving member 61. The second driving member 61 can drive the second pushing plate 62 to move upward along the second direction, and the second pushing plate 62 can drive the second separation block 234 to move upward so that the two positioning blocks 232 move away from the contact knife 101 to facilitate the loading and welding of the contacts 102.

[0070] In order to improve the welding efficiency of the upper electrode 171 and the lower electrode 172 and reduce the maintenance and adjustment frequency, the clamping mechanism 2 also includes a fixed seat 24, the positioning seat 21 is arranged on the turntable 1 through the fixed seat 24, the fixed seat 24 is fixedly arranged on the turntable 1, the positioning seat 21 is slidably connected with the fixing seat 24 through the second guide rail slider structure along the second direction, and a third elastic member (which can also be selected as a spring) is arranged between the positioning seat 21 and the fixing seat 24, and the third elastic member provides an elastic force upward along the second direction for the positioning seat 21. When the upper electrode 171 presses the contact 102 downward along the second direction, and at the same time drives the positioning seat 21 to descend along the second direction, so that the contact blade 101 abuts against the lower electrode 172, the upper electrode 171 and the lower electrode 172 are energized to achieve welding of the contact 102 and the contact blade 101. This structure allows the contact 102 and the contact blade 101 to be effectively welded without adjustment after slight wear of the upper electrode 171 or the lower electrode 172.

[0071] Furthermore, after the upper electrode 171 moves downward along the second direction so that the contact 102 and the contact knife 101 are clamped between the upper electrode 171 and the lower electrode 172, the two positioning plates 233 move away from each other along the first direction to disengage the contact 102, and then the upper electrode 171 and the lower electrode 172 are energized to weld the contact 102 and the contact knife 101 to reduce sparking and wear.
