[0002] Solder paste rewarming technology refers to the process of taking the solder paste out of the cold storage environment and placing it in the room temperature environment for a period of time before using it, so that the temperature of the solder paste is the same as the room temperature. This step is crucial to ensure the performance of the solder paste and the quality of welding. When the solder paste is in the cold state, the distribution of the flux and tin powder in it is uneven, and it needs to be evenly distributed through rewarming to give full play to the various characteristics of the solder paste.

The patented solder paste reheating device can effectively control the solder paste reheating time, and the solder paste cannot be removed during the solder paste reheating process.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: With regard to the problem of solder paste reheating, the existing solder paste reheating device, due to its traditional reheating method and the inability to limit and fix solder paste tubes of different sizes, makes it impossible to limit and fix solder paste tubes of different sizes, thereby reducing the overall applicability of the reheating device. Therefore, improving the solder paste reheating device so that it has the function of limiting and fixing solder paste tubes of different sizes will help to improve the applicability and convenience of the solder paste reheating device.

When limiting and fixing solder paste boxes 6 of different sizes, the staff first pulls the pull block 11 to make the surface of the pull block 11 slide in the inner cavity of the open groove 10. As the pull block 11 moves, the pull block 11 drives the surface of the slide column 8 to slide in the inner cavity of the circular groove 7, so that the slide column 8 squeezes the first spring 12 to accumulate force, and the slide column 8 drives the surface of the first slider 15 to slide in the inner cavity of the first slide groove 14. At the same time, the slide column 8 drives the surfaces of the arc clamping block 9 and the thermal insulation plate 13 to gradually separate from the surface of the solder paste box 6. At this time, the solder paste box 6 will not be clamped and limited by the arc clamping block 9 and the thermal insulation plate 13. The above-mentioned structure is arranged to facilitate the staff to clamp and limit solder paste boxes 6 of different sizes, further improving the applicability and convenience of the reheating body 1.

[0028] Reference Figure 3 and Figure 5 As shown, in this embodiment: the inner cavity of the circular groove 7 is fixedly connected with a first spring 12, and one end of the first spring 12 close to the sliding column 8 is fixedly connected to the sliding column 8. The staff pulls the pull block 11 to drive the sliding column 8 to move, so that the sliding column 8 squeezes the first spring 12 to store force, and the first spring 12 is set. The rebound force of the first spring 12 continuously pushes the sliding column 8 to move, so that the sliding column 8 pushes the arc clamping block 9 and the heat insulation sheet 13 to squeeze the solder paste box body 6 for limited fixing.

[0029] Reference Figure 3 As shown, in the present embodiment: one end of the arc-shaped clamp block 9 close to the solder paste box body 6 is fixedly connected with a heat insulating sheet 13, and the material of the heat insulating sheet 13 is polystyrene which has good heat insulating performance and pressure resistance. Through the setting of the heat insulating sheet 13, the properties of the heat insulating sheet 13 itself can effectively prevent heat from being lost along with the arc-shaped clamp block 9, resulting in a reduction in the temperature recovery effect.

As the pull block 11 moves, the pull block 11 drives the surface of the slide column 8 to slide in the inner cavity of the circular groove 7, so that the slide column 8 squeezes the first spring 12 to accumulate force, and the slide column 8 drives the surface of the first slider 15 to slide in the inner cavity of the first slide groove 14. At the same time, the slide column 8 drives the surfaces of the arc clamping block 9 and the thermal insulation sheet 13 to gradually separate from the surface of the solder paste box 6. At this time, the solder paste box 6 will not be clamped and limited by the arc clamping block 9 and the thermal insulation sheet 13.
