Description

Technical Field

[0001] This application relates to the field of electronic component processing technology, and more specifically, to a terminal continuous soldering mechanism. Background Technology

[0002] Terminal tinning is a process that involves applying solder to wire terminals, primarily used in electrical connections and electronic manufacturing. Its purpose is to improve conductivity, enhance soldering reliability, and prevent terminal oxidation.

[0003] Currently, the most common method for soldering terminals is still manual immersion of the terminals in a solder bath by workers. However, manual soldering is inefficient and produces uneven results. This repetitive labor is also very demanding and unsuitable for large-scale factory production. Therefore, some factories use purely machine-based methods for soldering terminals. However, terminals are usually mounted on flexible cables, making it difficult for ordinary machinery to accurately grip the cables. Only high-precision robotic arms can meet the requirements, but these are expensive, thus increasing the manufacturing cost of terminal soldering.

[0004] Therefore, it is necessary for the inventors to design a new terminal continuous soldering mechanism to overcome the above problems. Summary of the Invention

[0005] The main objective of this application is to provide a continuous terminal soldering mechanism to solve the problems of low efficiency of manual soldering and high cost of robotic arms in related technologies.

The trapezoidal groove is opened at the top of the side wall of the solder bath, and the trapezoidal docking part is fixedly disposed at the end of the positioning plate near the solder bath.

[0009] Optionally, a slider is fixedly provided at the bottom of the solder bath, and a slide rail is fixedly provided at the top of the mounting bracket, with the slider slidably connected to the slide rail.

[0010] Optionally, the drive assembly includes a first cylinder, which is fixedly mounted on the mounting bracket, and the telescopic end of the first cylinder is fixedly connected to the solder bath.

[0011] Optionally, the pressing component includes a second cylinder and a pressure plate. The second cylinder is located above the solder bath, and the telescopic end of the second cylinder is directly opposite the top opening of the solder bath.

[0013] Optionally, an anti-overflow groove is also fixedly provided on the outer wall of the tin pool.

[0014] Optionally, the bottom of the trapezoidal groove also has an inclined guide surface.

[0015] The terminal continuous soldering mechanism provided by this utility model has the following advantages compared with the prior art:

[0016] By setting a rotating turntable to align each terminal on the clamping member with the solder bath in sequence, and by pressing down the pressing member, the soldering work of the terminals is completed, eliminating manual operation by workers and improving the efficiency of terminal soldering.

[0028] like Figures 1 to 3As shown, a terminal continuous soldering mechanism includes a turntable 1 and a mounting frame 2. A plurality of clamping members are fixedly arranged on the turntable 1. A solder pool 3 is slidably arranged on the mounting frame 2. A pressing member is fixedly arranged on the top of the solder pool 3. A docking structure is fixedly arranged between the clamping members and the solder pool 3. A driving component is fixedly arranged between the solder pool 3 and the mounting frame 2.

[0029] Specifically, the turntable 1 is driven by an external drive unit to rotate and stop periodically. A clamping component holds the cable with terminals at its end. When the turntable 1 rotates the clamping component to a position matching the solder bath 3, it stops rotating and drives the entire solder bath 3 towards the clamping component, completing the mating structure between them. At this point, the terminal enters the upper part of the solder bath 3. Then, a pressing component pushes the terminal downwards into the solder bath 3 to complete the soldering process. After soldering is complete, the pressing component is reset, the solder bath 3 is retracted, and the turntable 1 continues to rotate so that the next terminal undergoes the same soldering operation.

[0030] In this embodiment, the rotating turntable 1 sequentially aligns each terminal on the clamping member with the solder bath 3, and the downward pressure of the pressing member completes the soldering process of the terminals. This eliminates manual operation by workers and improves the efficiency of terminal soldering. At the same time, this device has a simple structure and uses low-cost structural components, which greatly reduces the cost of terminal soldering compared to a robotic arm.

[0031] The clamping component includes a positioning plate 4, which is fixedly connected to the turntable 1. The top of the positioning plate 4 has a limiting groove 5 for clamping the cable. Specifically, in actual use, a clamping mechanism can be set up at the station before the terminal soldering to press the cable into the limiting groove 5, so as to prevent the cable from loosening when the terminal is soldered.

[0032] The docking structure includes a trapezoidal groove 6 and a trapezoidal docking part 7 that fit together. The trapezoidal groove 6 is formed on the top of the side wall of the solder pool 3, and the trapezoidal docking part 7 is fixedly disposed on the end of the positioning plate 4 near the solder pool 3. The bottom of the trapezoidal groove 6 also has an inclined guide surface 15. Specifically, the trapezoidal groove 6 and the trapezoidal docking part 7 are directly opposite each other. During docking, this prevents the solder pool 3 from moving too far, causing the clamping member to extend above the solder pool 3 and preventing the pressing member from pressing down properly. Since cables are usually relatively soft, the part of the cable not clamped by the clamping member will bend slightly under the action of gravity, which may cause the terminal to fail to enter the trapezoidal groove 6. In this case, the inclined guide surface 15 can prevent this from happening.

[0033] A slider 8 is fixedly installed at the bottom of the solder pool 3, and a slide rail 9 is fixedly installed at the top of the mounting bracket 2. The slider 8 is slidably connected to the slide rail 9. Specifically, the sliding connection between the slider 8 and the slide rail 9 has low resistance and stable sliding, which can reduce the splashing of solder in the solder pool 3.

[0034] The driving assembly includes a first cylinder 10, which is fixedly mounted on the mounting bracket 2. The telescopic end of the first cylinder 10 is fixedly connected to the solder pool 3. A connecting rod 13 is fixedly mounted on the side wall of the solder pool 3, with its end extending above the solder pool 3. A second cylinder 11 is fixedly mounted on the connecting rod 13. Specifically, the first cylinder 10 drives the sliding of the solder pool 3. During installation, a conditional structure can be provided between the connecting rod 13 and the first cylinder 10 to adjust the installation height of the first cylinder 10 to meet different working requirements.

[0035] The pressing component includes a second cylinder 11 and a pressure plate 12. The second cylinder 11 is located above the solder pool 3, and the telescopic end of the second cylinder 11 is directly opposite the top opening of the solder pool 3. The pressure plate 12 is fixedly connected to the telescopic end of the second cylinder 11. Specifically, the second cylinder 11 drives the pressure plate 12 to move, thereby pressing the terminal into the solder pool 3. The pressure plate 12 can be made of a material that is not easy to stick to solder, or a structure that is easy to disassemble and assemble can be designed between the pressure plate 12 and the telescopic end of the second cylinder 11 to periodically clean the solder that has stuck and solidified on the pressure plate 12.

[0036] An anti-overflow groove 14 is also fixedly installed on the outer wall of the tin pool 3. Specifically, the anti-overflow groove 14 can prevent tin from overflowing from the tin pool 3 and causing danger to the external environment.

[0037] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
