[0002] Terminals are increasingly widely used in various fields, including signal terminals, power terminals, and connection terminals, serving as connection points in circuits. In the electronics industry, electronic products typically require terminal assembly during manufacturing, connecting wires to terminals via soldering. Soldering is a welding method that uses a low-melting-point metal solder to melt and penetrate and fill the gaps at the joints of metal parts. Since the solder is often a tin-based alloy, it is called soldering. Previously, welding was performed manually using electric welding equipment. During manufacturing, the soldering process quality relied on manual control, resulting in outdated methods, low efficiency, poor reliability, and unstable quality. Therefore, there is a need to develop an automated terminal heating and soldering device to solve these problems. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] like Figures 1 to 5As shown, an automatic terminal heating and welding device includes a frame 01, a worktable 02, a positioning fixture 03, an X-axis drive assembly 04, a movable frame 05, a Z-axis drive assembly 06, a heating control box 07, and an induction coil 08. The worktable 02 is horizontally fixed on the frame 01. The positioning fixture 03 includes a fixture base plate 031, a base plate handle 032, a fixture cover plate 033, and a cover plate handle 034. Multiple sets of positioning posts 021 are provided above the worktable 02. Multiple sets of positioning holes 0311 are provided on the fixture base plate 031. The fixture base plate 031 is placed on the worktable 02, and the multiple sets of positioning posts 021 are inserted into the multiple sets of positioning holes 0311 one by one. Multiple sets of first magnets 0312 are provided on the fixture base plate 031 along the X-axis direction. A wire placement groove 0313 and a terminal placement groove 0314 are provided above the fixture base plate 031. Terminal placement slot 0314 is connected to the rear end of wire placement slot 0313. Base plate handle 032 is fixed on the upper left and right sides of fixture base plate 031. Fixture cover plate 033 is placed on fixture base plate 031 and corresponds to the upper part of wire placement slot 0313. Multiple sets of second magnets 0331 are arranged below fixture cover plate 033. The second magnets 0331 are in contact with the first magnets 0312. Cover plate handle 034 is fixed above fixture cover plate 033. X-axis drive assembly 04 is fixed on frame 01. Movable frame 05 is fixed on the power output end of X-axis drive assembly 04. Z-axis drive assembly 06 is fixed on movable frame 05. Heating control box 07 is fixed on the power output end of Z-axis drive assembly 06. Induction coil 08 is electrically connected to heating control box 07 and the induction heating end corresponds to the upper part of terminal placement slot 0314.

[0023] The connecting terminals and wires have been riveted in the previous process, initially fixing the connecting terminals to the rear end of the wires. Then, the connecting terminals and wires are placed in the terminal placement slot 0314 and wire placement slot 0313 on the fixture base plate 031, respectively. The fixture cover plate 033 is placed on the fixture base plate 031 through the cover plate handle 034. The first magnet 0312 and the second magnet 0331 attract each other, thereby pressing the fixture cover plate 033 against the wires, thus completing the positioning and fixing of multiple sets of wires. Next, the fixture base plate 031 is placed on the worktable 02 through the fixture handle, and the positioning post 021 is inserted into the positioning hole 0311, thereby quickly positioning the fixture base plate 03. Subsequently, under the driving action of the X-axis drive assembly 04 and the Z-axis drive assembly 06, the induction coil 08 moves sequentially above each set of terminals, and the induction coil 08 is energized through the heating control box 07, thereby heating the terminals and melting the solder embedded in the terminal riveting area, thus welding the terminals onto the wires. The advantages of this design are: it can quickly position and fix terminals and wires, and it can automatically perform welding processes on multiple sets of terminals, which not only improves welding efficiency, but also improves welding quality.

[0024] The fixture base plate 031 is also provided with a clearance groove 0315, which corresponds to the left and right sides of the terminal placement groove 0314. The left and right sides of the induction heating end of the induction coil 08 are bent downward and correspond to the clearance groove 0315.

[0025] By setting the clearance slot 0315, the induction heating end of the induction coil 08 can be partially surrounded by the outer periphery of the terminal, thereby improving the efficiency of induction heating.

[0026] Multiple sets of fixture cover plates 033 and cover plate handles 034 are arranged along the X-axis on the fixture base plate 031. This reduces the weight of a single fixture cover plate 033, making it easier for operators to pick up and put down the fixture cover plate 033. Furthermore, it allows for flexible selection of wire placement slots 0313 and terminal placement slots 0314 within a specific area of ​​the fixture base plate 031, rather than requiring all of them to be used, thus making operation more flexible.

[0027] This design also includes a protective cover 09 and a flip drive assembly 10. The protective cover 09 is rotatably mounted on the frame 01 and covers the worktable 02. The flip drive assembly 10 is fixed on the frame 01 and its power output end is fixedly connected to the protective cover 09. The flip drive assembly 10 is used to drive the protective cover 09 to flip.

[0028] After the fixture base plate 031 is placed on the workbench 02, the flip drive assembly 10 drives the protective cover 09 to close on the workbench 02. Then the equipment automatically performs the welding process. The protective cover 09 can protect the operator.

[0029] This design also includes a solder breaker 11, a connecting frame 12, and a solder rod guide 13. The solder breaker 11 is fixed on the movable frame 05, the connecting frame 12 is fixed on the induction coil 08, and the solder rod guide 13 is fixed on the connecting frame 12 and its angle is adjustable. The solder rod guide 13 is provided with a guide hole. After the solder breaker 11 passes through the guide hole, the solder rod passes through the guide hole and its end corresponds to the top of the terminal placement slot 0314.

[0030] For some terminal models, no solder is pre-embedded at the riveting position. Instead, the welding is carried out by simultaneously feeding the welding rod during welding. The welding rod passes through the solder breaker 11 and then through the welding rod guide tube 13 to reach the riveting position. Under the heating action of the induction coil 08, the end of the welding rod melts and forms solder at the riveting position, thus completing the welding.

[0031] This design also includes a cooling fan 14, which is fixed on the frame 01 and corresponds to one side of the workbench 02.

[0032] After the protective cover 09 is installed, in order to quickly dissipate the heat during welding, a cooling fan 14 is installed to dissipate the heat from the side of the frame 01, thus preventing the temperature inside the equipment from getting too high.

[0033] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
