[0029] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the application.
[0030] Please refer to Figure 1 , Figure 2 and Figure 3A brazing tool in this embodiment includes an upper cover 1, a high-temperature plastic plate 2 is installed under the upper cover 1, and a bottom bracket 3 is provided under the high-temperature plastic plate 2. The surfaces of the upper cover 1 and the high-temperature plastic plate 2 are both provided with a plurality of through-type first positioning holes 8, the upper surface of the bottom bracket 3 is provided with a board card outline 4, and the upper surface of the bottom bracket 3 is provided with a plurality of second positioning holes 13 and evenly distributed grooves 5. The positions of the plurality of first positioning holes 8 correspond to the positions of the plurality of second positioning holes 13 respectively. By defining the positional relationship between the first positioning holes 8 and the second positioning holes 13, it is convenient to subsequently combine the upper cover 1, the high-temperature plastic plate 2 and the bottom bracket 3 together, thereby facilitating subsequent brazing work.
[0031] It should be noted that the shape of the board outline 4 is the same as the outline of the board, so that the board can be inserted quickly and accurately, which reduces the assembly time and improves work efficiency. In addition, by providing the groove 5, bubbles can be prevented from being trapped. During the brazing process, due to heating, gas may be generated and retained between the board and the base 3, and the design of the groove 5 helps to provide an exhaust channel so that the gas can be discharged smoothly, thereby reducing the formation of bubbles during welding and avoiding welding defects. At the same time, the groove 5 can help regulate the conduction of heat so that the base 3 distributes the temperature more evenly during the heating process. By guiding the heat flow to flow on the surface of the base 3, the temperature of different areas is ensured to be consistent, reducing welding problems caused by local overheating or cooling. Finally, it needs to be explained that the reason why the groove 5 can enhance the clamping force on the board is because the board outline 4 can increase the friction between the base 3 and the board, preventing the board from being displaced due to vibration or movement during the brazing process.
[0032] See also Figure 1 、 Figure 2 and Figure 3 The upper cover 1 and the bottom bracket 3 are both made of metal, preferably aluminum alloy or stainless steel. By limiting the materials of the upper cover 1 and the bottom bracket 3, they can provide good temperature uniformity and optimize the quality of brazing by taking advantage of their thermal conductivity and strong structure. The high-temperature plastic plate 2 is a high-temperature resistant material with a low thermal expansion coefficient and a certain chemical stability. It is preferably polyimide or polyphenylene sulfide. By limiting the material of the high-temperature plastic plate 2, it can be ensured that the material can withstand the high temperature during brazing, avoiding deformation at high temperature and resulting in a decrease in welding accuracy. At the same time, no harmful gas is released at high temperature and no metal is corroded, thereby ensuring the cleanliness of the welding module.
[0033] See also Figure 1 、 Figure 3 and Figure 4The upper cover 1 and the high-temperature plastic plate 2 are provided with a plurality of through connection holes 6, and the inner wall of each connection hole 6 is threadedly connected with a connecting bolt 7, so that the upper cover 1 and the high-temperature plastic plate 2 are connected through the plurality of connecting bolts 7. The connecting hole 6 and the connecting bolt 7 can conveniently install the high-temperature plastic plate 2 on the bottom surface of the upper cover 1, and facilitate the disassembly of the high-temperature plastic plate 2.
[0034] Please refer to Figure 1 、 Figure 2 and Figure 4 The inner wall of each first positioning hole 8 is threadedly connected with a positioning bolt 9, and the upper cover 1, the high-temperature plastic plate 2 and the bottom support 3 are connected through the positioning bolt 9. The positioning bolt 9 can facilitate the connection of the upper cover 1, the high-temperature plastic plate 2 and the bottom support 3, and is beneficial to rapid disassembly and fixing. The outer part of each positioning bolt 9 is sleeved with a gasket 10. The gasket 10 can improve the stability of the positioning bolt 9 installed between the upper cover 1, the high-temperature plastic plate 2 and the bottom support 3. The upper surface of the bottom support 3 is provided with a pointing arrow 11 and a steel stamp area 12. The pointing arrow 11 and the steel stamp area 12 can mark the bottom support 3, which is convenient for quickly distinguishing the category of the tooling.
[0035] In the embodiment, the brazing tool can make the plate card more quickly placed on the bottom support 3 through the plate card contour 4, and the connection mode of the connecting bolt 7 and the positioning bolt 9 is relatively simple, which is convenient for rapid disassembly and fixing. The high-temperature plastic plate 2 is provided, which will not release harmful substances at high temperature, reduce pollution, and its material surface is smooth, which can prevent the accumulation of welding slag or pollutants in the welding process. The combination of the upper cover 1 and the high-temperature plastic plate 2 is helpful to arrange uniform pressure, so that the plate card and the bottom support 3 are evenly heated during the heating process, and the formation of bubbles caused by uneven temperature distribution during welding is reduced. Finally, the recess 5 can realize the effects of exhaust, bubble reduction, uniform heat conduction, enhanced clamping force, ventilation and cooling.
[0036] In summary, the device can reduce the time spent on positioning the center and cleanliness every time the plate is pressed, and the brazing module is fixed in the same position every time the plate is pressed, which prevents the brazing module from being unevenly stressed and generating a large number of bubbles, improves work efficiency, reduces costs, and reduces waste.
[0037] The working principle of the above embodiment is that: in use, first, the upper cover 1 and the high-temperature plastic plate 2 are connected through the connecting hole 6 and the connecting bolt 7, then the board card is placed according to the board card contour 4 opened on the surface of the bottom support 3, then the first positioning hole 8 on the combined upper cover 1 and high-temperature plastic plate 2 is aligned with the second positioning hole 13 opened on the surface of the bottom support 3, then the combined upper cover 1 and high-temperature plastic plate 2, the board card and the bottom support 3 are fixedly connected through the positioning bolt 9 and the gasket 10, and finally the bottom support 3 is heated and welded, in the heating process, the upper cover 1 and the high-temperature plastic plate 2 cover the board card and form a sealed structure with the bottom support 3, which helps to prevent dust or pollutants in the external environment from entering the welding area, thereby maintaining the cleanliness of the module, and the high-temperature plastic plate 2 can withstand high temperature in the brazing process, avoid deformation under high temperature to reduce the welding precision, and not release harmful gas and not corrode metal under high temperature, so as to ensure the cleanliness of the welding module, and the recess 5 can effectively realize exhaust and reduce bubbles, uniform heat conduction, enhance clamping force and the effects of ventilation and cooling.
