Description

Technical Field

[0001] The utility model relates to the technical field of soldering paste, in particular to a soldering paste cooling device. Background Technique

[0002] Soldering paste is a substance used to assist in the soldering of electronic components. It is usually a mixture of metal powders (such as tin powder or lead-tin alloy powder) and a combustible organic compound (such as rosin or other resins). In the process of electronic manufacturing, soldering paste is applied to the pads or other metal surfaces on the circuit board to promote the wetting effect during the soldering process, improve the soldering quality and efficiency. Soldering paste needs to be stored refrigerated before use to prevent changes in its chemical composition. After being applied to the circuit board, it is melted by heating (usually through the reflow soldering process) to melt the metal powder, so that the metal powder forms a good connection with the surface of the circuit board and other electronic components. Selecting the appropriate soldering paste is crucial for ensuring the reliability and performance of electronic products.

[0003] After assisting in soldering, the soldering paste needs to be cooled, so a cooling device is required. Although the traditional cooling device has a certain cooling capacity, it still has some deficiencies. For example, it is difficult to enclose the soldered object according to requirements, so it is easy for the soldered object to be displaced or dropped due to collision during the cooling process, thus affecting its cooling effect. In addition, its cooling structure is relatively fixed, so its cooling range is also relatively limited, making it difficult to cool the soldering paste more comprehensively. Therefore, a soldering paste cooling device is proposed to solve the above problems. Content of the Utility Model

[0025] Please refer to Figure 1-7 , the present utility model provides a technical solution:

[0026] A solder paste cooling device includes a base 1. Fixed columns 2 are fixedly connected to the four corners of the top of the base 1. A connecting bracket 3 is fixedly connected to the top of the fixed columns 2. A cooling support plate 4 is arranged between the connecting brackets 3. The left and right ends of the front wall and the rear wall of the cooling support plate 4 are connected to the connecting brackets 3 through connecting bolts 5. A surrounding component 6 is arranged above the cooling support plate 4. A plurality of heat dissipation fins 7 are arranged at equal intervals and fixedly connected to the bottom of the cooling support plate 4. A bottom plate 8 is fixedly connected to the center of the top of the base 1. An adjusting component 9 is arranged on the bottom plate 8. A cooling component 10 is arranged above the adjusting component 9.

[0027] The enclosure component 6 includes positioning insertion rods 601 fixedly connected to the four sides of the top wall of the cooling support plate 4, and an enclosure support plate 602 arranged above the positioning insertion rods 601. Positioning insertion holes 603 are arranged at equal intervals on the bottom wall of the enclosure support plate 602. The positioning insertion holes 603 and the positioning insertion rods 601 are set with equal numbers, corresponding positions, and matching specifications. The enclosure component 6 can provide good enclosure ability for the cooling support plate 4 when needed. Therefore, it is not easy for the welded object placed on the cooling support plate 4 to shift or fall due to collision during the cooling process, thus ensuring its cooling effect; The adjustment component 9 includes a vertical plate 901 fixedly connected to the rear side of the top of the bottom plate 8. A driving motor 902 is fixedly connected to the center of the rear wall of the vertical plate 901. The output end of the driving motor 902 penetrates the vertical plate 901 and a half gear 903 is fixedly connected to this end. An adjustment frame 904 with an open structure in the front and rear is arranged on the front side of the vertical plate 901. The adjustment frame 904 is sleeved outside the half gear 903. Convex teeth 905 corresponding to the position of the half gear 903 and matching specifications are arranged on both the inner top wall and the inner bottom wall of the adjustment frame 904. A moving groove 906 is arranged at the center of the inner cavity of the bottom plate 8. A moving support rod 907 is fixedly connected to the center of the bottom wall of the adjustment frame 904. A moving support block 908 is fixedly connected to the bottom end of the moving support rod 907. The moving support block 908 extends into the moving groove 906 and the adjustment frame 904 is slidably connected to the moving groove 906 through the moving support rod 907 and the moving support block 908. The adjustment component 9 can regularly reciprocally adjust the position of the cooling component 10. Therefore, the cooling range of the cooling component 10 can be made wider, so that the soldering paste can be cooled more comprehensively; The cooling component 10 includes a cooling box 1001. A connecting support column 1002 is fixedly connected to the center of the bottom of the cooling box 1001, and the cooling box 1001 is fixedly connected to the center of the top of the adjustment frame 904 through the connecting support column 1002. A cooling fan 1003 is arranged in the inner cavity of the cooling box 1001, and dust-proof nets 1004 are arranged on both the top wall and the bottom wall of the cooling box 1001. The cooling component 10 can cool the heat dissipation fins 7, that is, cool the soldering paste quickly at the same time.

[0028] Workflow: First, all electrical appliances are powered on. The fixed support column 2 can fixedly support the cooling support plate 4 through the connecting bracket 3.

The enclosure assembly 6 can provide good enclosure ability for the cooling support plate 4 when needed. Therefore, it is not easy for the welded objects placed on the cooling support plate 4 to shift or fall due to collision during the cooling process, ensuring its cooling effect. When enclosure is needed, just set the positioning jack 603 at the bottom of the enclosure support plate 602 on the positioning rod 601 for positioning. The disassembly is the same. The cooling support plate 4 is made of aluminum or copper. Therefore, the heat dissipation fins 7 can quickly absorb the heat on the welded objects through the material characteristics of the cooling support plate 4, enabling the soldering paste to cool quickly. The bottom plate 8 can support the adjustment assembly 9. The adjustment assembly 9 can regularly and reciprocally adjust the position of the cooling assembly 10. Therefore, the cooling range of the cooling assembly 10 can be made wider, enabling the soldering paste to be cooled more comprehensively. Start the driving motor 902. The driving motor 902 drives the semi-gear 903 to rotate through its output end. When the gear of the semi-gear 903 rotates to the upper convex tooth 905, it will push the adjustment frame 904 to move leftward through meshing. When the gear of the semi-gear 903 rotates to the lower convex tooth 905, it will push the adjustment frame 904 to move rightward through meshing, thereby driving the cooling assembly 10 to move simultaneously through the connecting support column 1002. When the adjustment frame 904 moves, it slides in the moving groove 906 through the moving rod 907 and the moving block 908. The cooling fan 1003 in the cooling assembly 10 can cool the heat dissipation fins 7, that is, cool the soldering paste quickly at the same time. The dust-proof net 1004 can block impurities in the air to prevent them from entering the cooling box 1001 and affecting the cooling fan 1003.
