The anti-slip groove 5, the first limiting groove 6, the second limiting groove 7, and the loading and unloading groove 8 realize the installation and limiting action of the four-way acquisition board body. The surface of the welding carrier 1 is respectively provided with a first groove 9, a second groove 10, and a support groove 11.

[0019] The positioning plane 2 is located at the upper end of the welding carrier 1, and the mounting hole 3 is located at the upper end of the positioning plane 2. Multiple mounting holes 3 are distributed in a linear array along the axial direction of the welding carrier 1. The mounting holes 3 are threaded through holes, and the coding plane 4 is located between two adjacent mounting holes 3.
[0020] Furthermore, the welding carrier 1 is fastened to the surface of the equipment through the mounting hole 3 , and the coding plane 4 facilitates coding to identify and distinguish the welding carrier 1 .
[0021] The anti-skid groove 5 is located at the lower end of the welding carrier 1 . The anti-skid groove 5 is arranged in a horizontal direction. A plurality of anti-skid grooves 5 are distributed in a linear array along the axis direction of the welding carrier 1 .
[0022] Furthermore, a four-way collecting plate is placed on the surface of the anti-skid groove 5, and a horizontally arranged anti-skid layer prevents the four-way collecting plate from sliding.
[0023] The first limiting groove 6 and the second limiting groove 7 are both located inside the anti-slip groove 5. The first limiting groove 6 is set horizontally, and the second limiting groove 7 is set vertically. The depths of the first limiting groove 6 and the second limiting groove 7 are both greater than the depth of the anti-slip groove 5. The two second limiting grooves 7 are symmetrically distributed with the axis of the welding carrier 1 as the center.
[0024] Furthermore, the first limiting groove 6 contacts the upper end of the four-way acquisition board, and the two second limiting grooves 7 contact the two sides of the four-way acquisition board respectively, thereby limiting the position of the four-way acquisition board.
[0025] The loading and unloading groove 8 is located inside the anti-slip groove 5 . The loading and unloading groove 8 is vertically arranged and passes through the surface of the welding carrier 1 . A plurality of loading and unloading grooves 8 are distributed in a linear array along the axis direction of the welding carrier 1 .
[0026] Furthermore, the loading and unloading groove 8 passes through the surface of the welding carrier 1, so as to facilitate the movement and fixation of the four-way acquisition board on the surface of the welding carrier 1.
[0027] The first type groove 9 is located above the anti-slip groove 5, the first type groove 9 is set horizontally, the second type groove 10 is set vertically, the support groove 11 is located above the second type groove 10, and the depth of the second type groove 10 is greater than the depth of the first type groove 9, the depth of the first limiting groove 6 and the depth of the support groove 11. Multiple second type grooves 10 are distributed in a linear array along the axial direction of the welding carrier 1.
[0028] Furthermore, the first groove 9 and the second groove 10 position the pin portion of the four-way acquisition board to avoid collision during assembly and movement of the device and ensure stability during welding.
[0029] By setting the anti-skid groove 5, the bottom surface of the four-way acquisition board is prevented from skidding and heat dissipation, the first limit groove 6 and the second limit groove 7 are set to limit the installation of the body of the four-way acquisition board, and the second groove 10 and the support groove 11 are set to position and support the pins of the four-way acquisition board, the technical problems of the existing mold having no reasonable fixing means, being difficult to achieve high-precision welding, and having low welding rate and welding accuracy are solved.
[0030] Working principle:
[0031] Before use, the lower surface of the four-way acquisition board is slidably connected to the surface of the anti-slip groove 5, and the two sides of the four-way acquisition board are placed on the surface of the second limiting groove 7. The two sides of the four-way acquisition board are limited by two second limiting grooves 7 symmetrically arranged with the welding carrier 1 as the axis, and the upper end of the four-way acquisition board body is contacted with the horizontal first limiting groove 6 to keep the four-way acquisition board horizontally placed. The loading and unloading groove 8 arranged inside the anti-slip groove 5 passes through the surface of the welding carrier 1. Multiple loading and unloading grooves 8 are arranged vertically, which is convenient for loading and unloading the four-way acquisition board above the welding carrier 1 and moving the welding carrier 1 body. The first groove 9 and the second groove 10 on the upper end of the welding carrier 1 are used to position the pins at the front end of the four-way acquisition board, so as to facilitate high-precision welding of the four-way acquisition board and avoid the shaking caused by the movement of the welding carrier 1 during the installation, which leads to the deviation of the main body of the four-way acquisition board and the pins of the four-way acquisition board, resulting in defects such as cold welding. A plurality of mounting holes 3 distributed in an array along the horizontal direction are arranged above the welding carrier 1, and a coding plane 4 is arranged above the welding carrier 1. Coding in this area can identify the model of the welding carrier 1 and distinguish the same type of welding carriers 1.
