[0002] Tinning refers to the process of coating the pins of components with solder paste to achieve a good connection with the soldering substrate. Currently, most components need to be tinned before soldering to ensure the reliability and stability of the connection. Tinning can form a strong electrical connection between the pins and pads of components during soldering. Tinning can effectively reduce harmful factors such as oxides generated during soldering, thereby improving the reliability of soldering. After tinning, the pin surface of the component will become smooth, which is convenient for automated equipment to grab and assemble.

[0003] In the prior art, when tinning components, the nozzle is used to complete the tinning process through the corresponding nozzle actuator on the tinning machine, and the nozzle is reset after the tinning is completed; however, the tinning machine partially uses an overflow tin pot and partially uses a static open tin pot.

Therefore, we propose an anti-oxidation protection device for the tinning machine to solve the above problem. Utility Model Content

A tin pot 2 is fixedly connected to the interior of the shell 1, and a motor 4 is fixedly connected to the outer wall of the frame 3. A circular hole is opened on the outer wall of the frame 3, and the inner wall of the circular hole is rotatably connected to the outer wall of the output shaft of the motor 4. A driving mechanism is provided on the outer wall of the frame 3, and a scraper mechanism is provided on the outer wall of the frame 3.

[0022] The outer wall of the frame 3 is fixedly connected with an assembly plate 13, and the top of the shell 1 is fixedly connected with a side plate 14. An L-shaped plate can be added to the side plate 14. When the scraper 12 moves and contacts the L-shaped plate, the electric push rod 15 drives the scraper 12 to move upward, and the outer wall of the scraper 12 is squeezed with the outer wall of the L-shaped plate, so that the tin slag on the scraper 12 falls onto the side plate 14, and the tin slag is collected. The outer wall of the shell 1 is fixedly connected with an electric push rod 15, and the top of the output end of the electric push rod 15 is fixedly connected to the outer wall of the frame 3. The operation of the electric push rod 15 drives the frame 3 to rise and fall as a whole, which is convenient for scraping tin slag at different heights.

[0023] The driving mechanism includes a first synchronous pulley 5, one end of the output shaft of the motor 4 is fixedly connected to the outer wall of the first synchronous pulley 5, and the outer wall of the frame 3 is rotatably connected to the second synchronous pulley 6. When the motor 4 runs, the transmission belt 7 drives the two guide blocks 9 to move along the guide rail 8.

[0024] The scraper mechanism includes a tin cover 11, which is located on the top of the tin pot 2. The outer wall of the frame 3 is fixedly connected to a guide rail 8, and the outer wall of the guide rail 8 is slidably sleeved with two guide blocks 9.

The bottom of the tin cover 11 is fixedly connected to a scraper 12.

[0025] Working principle: When in use, when the existing suction nozzle actuator moves to the top of the tin pot 2, the motor 4 is operated to rotate the first synchronous pulley 5, and the rotation of the first synchronous pulley 5 causes the transmission belt 7 and the second synchronous pulley 6 to rotate, and the two guide blocks 9 move along the guide rail 8, driving the L-shaped bracket 10 and the tin cover 11 to move, and the movement of the tin cover 11 drives the scraper 12 to move, and the tin slag in the tin pot 2 is automatically scraped off, and the electric push rod 15 is operated to drive the frame 3 to rise and fall as a whole, so as to facilitate the scraping of tin slag at different heights. After the tinning is completed, the suction nozzle is reset, and at the same time, the motor 4 and the electric push rod 15 are operated to reset, so that the tin cover 11 closes the tin pot 2, reducing the contact between the tin liquid and the air and reducing the risk of oxidation.
