The advantage of this process is that the temperature is easy to control, and oxidation can be avoided during the soldering process. When the existing equipment performs soldering operations on components and circuit boards, the fixation is prone to deviation, affecting the soldering accuracy.

A plurality of support members are respectively installed at the top of the loading plate 1 and around the fixing groove 6. The temperature measurement module 3 is installed in the installation groove 2 through bolts

[0023] During use, the fixing groove 6 is located at the center of the top of the loading plate 1, and the temperature measurement sensors 4 are respectively located around the fixing groove 6. The temperature measurement module 3 can detect the temperature of each position of the workpiece through a plurality of temperature measurement sensors 4. The support members can support the workpiece upward. The clamping assembly can clamp and fix the workpiece, improving the stability of the loading plate 1 for fixing the workpiece and preventing the workpiece from shifting or detaching

[0024] In one embodiment, specifically, the clamping assembly includes a fixing frame 5 installed at the top of the loading plate 1 and near one side. A fixing groove 6 is provided at the top of the loading plate 1 and near the other side. A screw 7 penetrates through the inside of the fixing groove 6. A sliding block 8 is sleeved outside the screw 7 inside the fixing groove 6. The top of the sliding block 8 is connected to a clamping frame 9. The bottom of the clamping frame 9 is connected with guide blocks 13 near both ends. Guide grooves 14 are respectively provided on both sides of the fixing groove 6 at the top of the loading plate 1. The guide blocks 13 are slidably connected with the guide grooves 14. The screw 7 penetrates through the sliding block 8 and is screwed with it. The sliding block 8 is slidably connected with the fixing groove 6

[0025] Among them, both the fixing frame 5 and the clamping frame 9 are in a frame shape. The cross-sections of the fixing frame 5 and the clamping frame 9 are U-shaped. The guiding groove 14 can guide and limit the clamping frame 9 through the guiding block 13 to prevent the clamping frame 9 from shifting. By using the screw rod 7, the sliding block 8 can be driven to slide in the fixing groove 6, so that the sliding block 8 drives the clamping frame 9 to approach or move away from the fixing frame 5, facilitating the clamping and fixing, taking, placing, and replacement of the workpiece by the clamping frame 9 and the fixing frame 5.

[0026] Furthermore, the support member includes a plurality of support columns 10 installed on the top of the loading plate 1 and surrounding the fixing groove 6. A cushion block 11 for supporting the workpiece is installed inside the support columns 10. An elastic frame 12 is connected between the inner sides of the support columns 10 and at the bottom of the cushion block 11. Two elastic plates 15 are connected to the inner side of the elastic frame 12. An anti-detachment ring 18 is connected to the bottom of the cushion block 11.

At the same time, the first anti-slip pad 16 and the second anti-slip pad 17 can protect the workpiece from being knocked.

[0029] The working principle of the present utility model:

[0030] First, place the workpiece on the first anti-slip pad 16 on the top of the cushion block 11. The cushion block 11 presses down on the elastic frame 12 through the anti-detachment ring 18. Due to the mutual action of forces, at this time, the two elastic plates 15 support the elastic frame 12 upward, and at the same time, the elastic frame 12 supports the cushion block 11 upward. At the same time, the support column 10 supports the workpiece through the cushion block 11. Then, place one side of the workpiece into one side of the fixing frame 5, and then rotate the screw rod 7 to drive the sliding block 8 to slide in the fixing groove 6. Then, the sliding block 8 drives the clamping frame 9 to approach the fixing frame 5. At the same time, the clamping frame 9 drives the guiding block 13 to slide in the guiding groove 14. Then, the clamping frame 9 and the fixing frame 5 clamp and fix the workpiece on the top of the cushion block 11. Then, use the temperature measurement module 3 to detect the temperature of each position of the workpiece through a plurality of temperature sensors 4.
