Description

Technical Field

[0001] This utility model relates to the field of tin furnace technology, specifically a tin furnace component for a laser paint stripping soldering turntable. Background Technology

[0002] The solder pot of the solder stripping rotary machine is a key piece of equipment used in the wave soldering process of circuit board assembly. It heats the tin alloy to a liquid state to form a stable wave, which immerses the pads and component leads on the circuit board into the molten tin to complete the soldering. The design of the solder pot must ensure that the molten tin temperature is uniform and the wave is stable in order to guarantee the soldering quality.

[0003] Solder baths are an indispensable component for achieving high-quality soldering, but they still have certain problems: 1) poor soldering quality; 2) during the soldering process, the continuous loss of the solder pool will cause fluctuations in the liquid level, which will affect the soldering accuracy; 3) high energy consumption. Therefore, in view of the above situation, there is an urgent need to develop a solder bath component for laser paint stripping soldering turntables to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide a solder furnace assembly for a laser soldering turntable for removing solder coating, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a solder pot assembly for a laser soldering turntable, comprising a base, a main solder pot, a slide rail and a solder pot lifting assembly, wherein the main solder pot is fixed on the base, the slide rail is fixed at the top edge of the base, a slider is slidably mounted on the slide rail, the solder pot lifting assembly is fixed on the slider, and a drive assembly for driving the slider is fixed at the top of the slide rail.

[0006] The solder pot lifting assembly includes a mounting frame, an exhaust bend, and a secondary solder pot. The mounting frame is fixed on the slider. A connector a is installed on one side of the exhaust bend, and the exhaust bend is fixed to the side of the mounting frame through connector a. A connector b is fixed to the side wall of the secondary solder pot, and the secondary solder pot is fixed to the bottom edge of the mounting frame through connector b.

[0007] Preferably, an overflow baffle is fixedly provided at the edge of the main solder pot, and a slag pool is fixedly provided on one side of the main solder pot. The overflow baffle has a notch at the top edge near the slag pool. Specifically, the overflow baffle can prevent the solder slag formed during the soldering process from escaping everywhere. With the help of the scraping mechanism, the solder slag on the surface of the solder pool can be scraped into the slag pool through the notch.

[0008] Preferably, the inlet end of the exhaust bend is equipped with a fume hood, and the outlet end of the exhaust bend is equipped with an interface. Specifically, the fume hood, in conjunction with the exhaust bend, can discharge the gas generated during the soldering process through the pipe.

[0009] Preferably, there are four exhaust bends and auxiliary soldering furnaces in total. The fume hood of the exhaust bend is located diagonally above the auxiliary soldering furnace. Specifically, the exhaust gas generated during the soldering process can be guided into the exhaust bend through the fume hood above, thereby improving the exhaust gas discharge efficiency.

[0010] Preferably, the main solder furnace is equipped with a heating element for heating the solder bath. Specifically, the heating element heats the solder alloy in the main solder furnace to keep it in a liquid state.

[0011] Compared with the prior art, this utility model provides a solder furnace assembly for a laser soldering turntable, which has the following advantages:

[0012] It adopts a design that combines a fixed main solder pot with a movable auxiliary solder pot. The main solder pot maintains a stable liquid solder temperature and flow waveform, while the auxiliary solder pot can precisely control the soldering depth and time through a lifting mechanism, ensuring uniform and full solder joints and improving soldering reliability. Moreover, the auxiliary solder pot is only raised when needed, reducing the exposure time of liquid solder and heat loss, thus reducing energy consumption. As solder is constantly consumed during continuous soldering, the solder liquid level will gradually decrease. The auxiliary solder pot lifting function enables the equipment to maintain a stable liquid level in the auxiliary solder pot even when solder consumption is severe and the solder liquid level is low, thereby ensuring soldering accuracy and quality. At the same time, the embedded design between the main solder pot and the auxiliary solder pot saves equipment floor space and facilitates production line layout and management.

[0019] Example:

[0020] Please see Figures 1-2 This utility model provides a technical solution: a solder pot assembly for a laser soldering turntable, including a base 10, a main solder pot 20, a slide rail 40 and a solder pot lifting assembly 30. The main solder pot 20 is fixed on the base 10, the slide rail 40 is fixed at the top edge of the base 10, a slider 401 is slidably mounted on the slide rail 40, the solder pot lifting assembly 30 is fixed on the slider 401, and a driving assembly 50 for driving the slider 401 to move is fixed on the top of the slide rail 40.

[0021] The solder pot lifting assembly 30 includes a mounting frame 301, an exhaust pipe 302, and a secondary solder pot 303. The mounting frame 301 is fixed on the slider 401. A connector a3023 is installed on one side of the exhaust pipe 302, and the exhaust pipe 302 is fixed to the side of the mounting frame 301 through the connector a3023. A connector b3031 is fixed to the side wall of the secondary solder pot 303, and the secondary solder pot 303 is fixed to the bottom edge of the mounting frame 301 through the connector b3031.

[0022] Preferably, an overflow baffle 201 is fixedly provided on the edge of the main solder pot 20, and a slag pool 202 is fixedly provided on one side of the main solder pot 20. The overflow baffle 201 has a notch near the top edge of the slag pool 202. Specifically, the overflow baffle 201 can prevent the solder slag formed during the soldering process from escaping everywhere. With the help of the scraping mechanism, the solder slag on the surface of the solder pool can be scraped into the slag pool 202 through the notch.

[0023] Preferably, the inlet end of the exhaust bend 302 is fixedly provided with a fume hood 3021, and the outlet end of the exhaust bend 302 is fixedly provided with an interface 3022. Specifically, the fume hood 3021, in conjunction with the exhaust bend 302, can discharge the gas generated during the soldering process through the pipe.

[0024] Preferably, there are four exhaust bends 302 and auxiliary soldering furnace 303. The fume hood 3021 of the exhaust bend 302 is located diagonally above the auxiliary soldering furnace 303. Specifically, the exhaust gas generated during the soldering process can be introduced into the exhaust bend 302 through the fume hood 3021 above, thereby improving the exhaust gas discharge efficiency.

[0025] Preferably, the main solder pot 20 is equipped with a heating element for heating the solder bath. Specifically, the heating element heats the solder alloy in the main solder pot 20 to keep it in a liquid state.

[0026] Working principle: The heating element in the main solder pot 20 heats and keeps the solder alloy inside in a liquid state. When the laser paint stripping soldering turntable drives the copper coil to the soldering station, the drive component 50 drives the slider 401 and the auxiliary solder pot 303 to rise to a certain height along the slide rail 40. The auxiliary solder pot 303 drives the liquid solder alloy inside to contact the soldering part of the copper coil to realize the soldering operation. Then the drive component 50 drives the slider 401 and the auxiliary solder pot 303 to descend to the initial position. The exhaust pipe is connected to the interface 3022 of the exhaust pipe 302. The exhaust gas generated during soldering is introduced into the exhaust pipe 302 by the fume hood 3021 above it, and finally discharged through the exhaust pipe. With the help of the turning mechanism of the laser paint stripping soldering turntable, the residue left on the surface of the solder pool during the soldering process is pushed into the slag pool 202, keeping the surface of the solder pool clean.
