Description

Technical Field

[0001] The utility model relates to the technical field of high-frequency transformer production, in particular to a soldering device used for high-frequency transformer processing. Background Art

[0002] A high-frequency transformer is a power transformer with an operating frequency exceeding the medium frequency. It is mainly used as a high-frequency switching power supply transformer in a high-frequency switching power supply. It is also used as a high-frequency inverter power supply transformer in a high-frequency inverter power supply and a high-frequency inverter welding machine. Soldering is a processing flow of a high-frequency transformer. It is mainly used to bond the pins of the high-frequency transformer together, so that the high-frequency transformer can be welded to another mechanism when it is used later.

[0003] A search of a Chinese patent with publication number CN215545618U discloses a soldering device for a high-frequency transformer.

[0004] The utility model includes a base and a tin pool.

The tin pool is located between the four support columns, and the four corners of the lower surface of the tin pool are fixedly connected to first lifting rods. The lower ends of the four first lifting rods are slidably sleeved with sleeves. A plurality of electric push rods are fixedly connected to the middle position of the lower surface of the tin pool, and the upper ends of the four support columns are slidably connected to second lifting rods. The soldering equipment of the utility model can avoid burns that may occur when workers use clamps to clamp high-frequency transformers. Multiple high-frequency transformers can be soldered at one time, reducing workers' workload and improving work efficiency. It can also ensure that the portions of the high-frequency transformer pins immersed in the tin pool are equal, thereby ensuring the quality of the solder.

[0005] However, this patent still has the following problems: although the device can clamp and fix the high-frequency transformer and avoid manual activities to place the high-frequency inverter into the tin pool, when fixing the high-frequency inverter, the device needs to fix the high-frequency transformer with bolts after each high-frequency transformer is placed in the clamping frame, which makes the high-frequency transformer more time-consuming to install and affects the processing efficiency. Utility Model Content

In this way, the high-frequency transformer can be quickly placed in the U-shaped shell and a certain clamping effect can be obtained. After multiple high-frequency transformers are placed in the U-shaped shell, the second clamping plate can be rotated to push the high-frequency transformer, so that the spring can be further compressed, thereby increasing the clamping force on the high-frequency transformer and ensuring that the high-frequency transformer will not fall during the soldering process. After the high-frequency transformer in one of the U-shaped shells is installed, the steering rod can be driven by the servo motor to rotate downward by ninety degrees, so that the inside of another U-shaped shell where the high-frequency transformer is not installed can continue to be installed, thereby expanding the total number of high-frequency transformers installed.

[0023] See also Figures 1-6A soldering device for high-frequency transformer processing includes a workbench 1 and a tin pool 2. The top of the workbench 1 is provided with a clamping mechanism 3, a scraping mechanism 4 and a protective mechanism 5;

[0024] The clamping mechanism 3 can clamp multiple high-frequency transformers together and enable continuous soldering of high-frequency transformers. The scraping mechanism 4 can automatically clean the surface of the tin pool 2. The protective mechanism 5 can protect the high-frequency transformers during installation and removal.

[0025] The clamping mechanism 3 includes a support frame 301, which is fixed to the top of the workbench 1. A mounting frame 302 is fixed to the surface of the support frame 301, a linear module 303 is fixed to the surface of the mounting frame 302, a mounting platform 304 is fixed to the surface of the moving part of the linear module 303, a servo motor 313 is fixed to the surface of the mounting platform 304, the output shaft of the servo motor 313 passes through the mounting platform 304 and is fixed to a steering rod 305, one end of the steering rod 305 is rotatably connected to the surface of the mounting platform 304 Two mounting plates 306 are fixed on the surface of the steering rod 305, a U-shaped shell 307 is fixed on the surface of the mounting plate 306, a spring 308 is fixed on the surface of the U-shaped shell 307, a first clamping plate 309 is fixed on the surface of the spring 308, a screw 310 is threaded through the surface of the U-shaped shell 307, one end of the screw 310 is rotatably connected to the second clamping plate 311, the second clamping plate 311 is slidably connected to the surface of the U-shaped shell 307, and the first clamping plate 309 and the second clamping plate 311 are both wedge-shaped structures.

[0026] When installing the high-frequency transformer, the servo motor 313 can first be used to drive the steering rod 305 to rotate ninety degrees, so that the lower U-shaped shell 307 can rotate upward, so that the operator can more easily place the high-frequency transformer into the U-shaped shell 307. During the placement of the high-frequency transformer, the high-frequency transformer will first contact the inclined surfaces of the first clamping plate 309 and the second clamping plate 311, so that the first clamping plate 309 can be pushed and the spring 308 can be compressed. This allows the high-frequency transformer to be quickly placed into the U-shaped shell 307 and obtain a certain clamping effect. After multiple high-frequency transformers are placed into the U-shaped shell 307, the screw 310 can be rotated to make the second clamping plate 311 push the high-frequency transformer, so that the spring 308 can be further compressed, thereby increasing the clamping force on the high-frequency transformer. To ensure that the high-frequency transformer will not fall during the soldering process, after the high-frequency transformer inside one of the U-shaped shells 307 is installed, the servo motor 313 can be used to drive the steering rod 305 to rotate downward by ninety degrees, so that the installation inside the other U-shaped shell 307 without the high-frequency transformer can continue, thereby expanding the total installation volume of high-frequency transformers. When soldering, the linear module 303 drives the mounting platform 304 to move downward, so that the surface of the high-frequency transformer inside the lower U-shaped shell 307 can contact the tin solution inside the tin pool 2, thereby completing the soldering operation of the high-frequency transformer inside the U-shaped shell 307 on one side. After that, the linear module 303 and the servo motor 313 can be operated again, so that the U-shaped shell 307 with the unsoldered high-frequency transformer can be rotated and moved downward, thereby completing the continuous soldering processing operation of multiple groups of high-frequency transformers.

[0027] Furthermore, the scraping mechanism 4 includes a first bracket 401, which is fixed to the top of the workbench 1. An extension plate 402 is fixed to the top of the first bracket 401. A cylinder 403 is fixed to the surface of the extension plate 402. One end of the cylinder 403 passes through the extension plate 402 and is fixed with a scraper 404. The scraper 404 is slidably connected to the top of the tin pool 2.

[0028] After long-term operation, there will be a lot of residue on the top of the tin pool 2. By starting the cylinder 403, the scraper 404 can be driven to slide on the top of the tin pool 2, so that the scraper 404 can scrape off the residue on the top of the tin pool 2, making it more convenient to clean the top of the tin pool 2.

[0029] Furthermore, the protection mechanism 5 includes a second bracket 501, which is fixed to the top of the workbench 1. A steering motor 502 is fixed to the bottom of the second bracket 501. The output shaft of the steering motor 502 passes through the second bracket 501 and is fixed to a connecting plate 503. A collecting shell 504 is detachably connected to the surface of the connecting plate 503. The collecting shell 504 is located above the tin pool 2.

[0030] When the high-frequency transformer is installed on the surface of the U-shaped shell 307 or taken out from the inside of the U-shaped shell 307, the connecting plate 503 can be driven to rotate by the steering motor 502 so that the collecting shell 504 can be turned over to the top of the tin pool 2, so that the collecting shell 504 can shield the top of the tin pool 2, thereby preventing the high-frequency transformer from falling into the inside of the tin pool 2 due to installation errors or when it is not held firmly when taken out.

[0031] Furthermore, a telescopic rod 312 is provided inside the spring 308 , one end of the telescopic rod 312 is fixedly connected to the inner wall of the U-shaped shell 307 , and the other end of the telescopic rod 312 is fixedly connected to the surface of the first splint 309 ;

[0032] The telescopic rod 312 can be extended and retracted, and at the same time, the telescopic rod 312 can also support the first splint 309 to prevent the first splint 309 from moving downward.

[0033] Furthermore, a guide rod 405 is slidably passed through the surface of the extension plate 402, and one end of the guide rod 405 is fixedly connected to the surface of the scraper 404;

[0034] When the scraper 404 moves, the guide rod 405 slides on the surface of the extension plate 402, so that the scraper 404 can obtain a guiding effect, thereby preventing the scraper 404 from tilting when moving.

[0035] Furthermore, a slide rail 505 is fixed to the top of the second bracket 501. Three sliders 506 are slidably connected to the surface of the slide rail 505. The top of the slider 506 is fixedly connected to the bottom of the connecting plate 503. A controller 6 is fixed to the top of the workbench 1. The controller 6 is electrically connected to the steering motor 502, the cylinder 403, the servo motor 313 and the linear module 303.

[0036] The connecting plate 503 can drive the slider 506 to slide on the surface of the slide rail 505, so that the connecting plate 503 is better supported, thereby improving the stability of the connecting plate 503 during rotation, and the controller 6 can operate multiple devices.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
