The fixture lacks a structure for collecting and treating the waste gas and slag generated during welding, which endangers the health of operators and affects their life safety. Therefore, we need to propose a welding fixture for circuit board processing. Summary of the Invention

[0005] The purpose of this utility model is to provide a welding fixture for circuit board processing, which has the advantage of collecting and treating the waste gas and slag generated during welding, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a welding fixture for circuit board processing, including a workbench, a partition is provided on the top of the workbench, and a processing component for collecting and treating the waste gas and slag generated during welding is provided below the partition and at the bottom of the workbench.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention utilizes a combination of a guide funnel, a three-way pipe, an isolation net, a treatment box, a purification mechanism, an exhaust pipe, an exhaust fan, and a waste collection box. During welding, fumes and spatter are drawn downwards through the perforated structure of the partition under the negative pressure of the exhaust fan. The guide funnel converges and directs the airflow, preventing pollutants from spreading to the work area. After the mixed airflow enters the three-way pipe, the reduced flow velocity and the mechanical interception of the inclined isolation net cause solid waste to be trapped and fall into the waste collection box. Gaseous pollutants continue to flow into the treatment box, where the purification mechanism purifies the exhaust gas before discharge. This allows for the collection and treatment of welding fumes and waste, effectively preventing welding fumes from escaping, reducing the risk of operators inhaling harmful gases, and improving the protection of operators' health.

[0019] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained through the structures pointed out in the description and the accompanying drawings. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a welding fixture for circuit board processing, including a workbench 1, a partition 2 is provided on the top of the workbench 1, a plurality of holes are uniformly opened through the top of the partition 2, and a processing component for collecting and treating the waste gas and slag generated during welding is provided below the partition 2 and at the bottom of the workbench 1.

[0027] Preferably, the processing components include: a guide funnel 3, a three-way pipe 4, an isolation net 5, a processing box 6, a purification mechanism, an exhaust pipe 7, an exhaust fan 8, and a waste collection box 9. The guide funnel 3 is installed at the bottom of the workbench 1. The bottom end of the guide funnel 3 is connected to the three-way pipe 4. An isolation net 5 is installed at an angle inside one end of the three-way pipe 4. The processing box 6 is connected to one side of the isolation net 5 and at one end of the three-way pipe 4. The processing box 6 is equipped with a purification mechanism for purifying the waste gas. An exhaust pipe 7 is installed at one end of the processing box 6. An exhaust fan 8 is installed inside the exhaust pipe 7. The other end of the three-way pipe 4 is connected to the waste collection box 9.

[0028] Specifically, through the coordinated use of the guide funnel 3, the three-way pipe 4, the isolation net 5, the treatment box 6, the purification mechanism, the exhaust pipe 7, the exhaust fan 8, and the waste collection box 9, the fumes and spatter generated during welding are drawn downwards through the hollow structure of the partition 2 under the negative pressure of the exhaust fan 8. The guide funnel 3 converges and guides the airflow to prevent pollutants from spreading to the working area. After the mixed airflow enters the three-way pipe 4, the solid waste is intercepted by the isolation net 5 due to the reduced flow velocity and the mechanical interception effect of the inclined isolation net 5, and slides down to the waste collection box 9. The gaseous pollutants continue to flow to the treatment box 6, where the exhaust gas is purified by the purification mechanism inside the treatment box 6 before being discharged. This allows for the collection and treatment of welding exhaust gas and waste, effectively preventing welding fumes from escaping, reducing the risk of operators inhaling harmful gases, and improving the protection of operators' health.

[0029] Preferably, the purification mechanism includes: activated carbon blocks 10, mounting frame 11, filter plate 12, and mounting groove 13. Several sets of activated carbon blocks 10 are located at one end of the interior of the treatment box 6.

The filter plate 12 is installed inside the mounting frame 11. The mounting groove 13 is opened at one end of the inner wall of the treatment box 6. The interior of the mounting groove 13 is adapted to the surface of the mounting frame 11, and the mounting frame 11 is slidably connected to the inner wall of the mounting groove 13. First, the filter plate 12 intercepts PM2.5 particles, and then the activated carbon blocks 10 adsorb organic gases and remove odors, thereby reducing the heavy metal content in the purified exhaust gas. At the same time, the sliding design of the mounting frame 11 and the mounting groove 13 allows the filter plate 12 to be quickly pulled out for easy replacement or cleaning.

[0030] Preferably, a cover 14 is fitted to the top of the processing box 6. An installation mechanism for installing the cover 14 is provided between the cover 14 and the top of the processing box 6.

One end of the mounting rod 16 passes through the top of the cover 14 and extends to the bottom of the cover 14, where it is threadedly connected to the inner cavity of the mounting hole 15. The through hole 17 is opened through the top of the cover 14, and the interior of the through hole 17 is fitted to the bottom end of the mounting rod 16. The bottom end of the mounting rod 16 is inserted into the inner cavity of the through hole 17. The cover 14 is fixed to the top of the processing box 6 by the threaded mounting rod 16 and the mounting hole 15, which facilitates opening the cover for maintenance.

[0031] Preferably, a protective frame 18 is installed on the top of the partition 2 and on the top of the workbench 1. The protective frame 18 can block welding slag splashes and reduce the risk of burns. At both ends of the protective frame 18 and on the top of the partition 2, clamping components for clamping the circuit board are provided. The clamping components include: telescopic rods 19, clamping seats 20, clamping rods 21, limiting plates 22, telescopic springs 23, and clamping plates 24.

The telescopic ends of the telescopic rods 19 and inside the protective frame 18 are connected to the clamping seats 20. Two sets of clamping plates are slidably connected at both ends of the clamping seats 20. A limit plate 22 is installed at one end of the clamping rod 21 inside the clamping seat 20. A telescopic spring 23 is provided on one side of the limit plate 22 at one end of the clamping rod 21. A clamping plate 24 is connected to the other end of the clamping rod 21 at the corresponding position. The telescopic spring 23 and the clamping rod 21 are linked together to adapt to different types of circuit boards and provide uniform pressure on irregularly shaped boards to avoid damage to components caused by local stress. The clamping plate 24 is made of anti-static material and only contacts the edge of the circuit board to avoid blocking the solder pads or test points, ensuring that soldering and testing are carried out simultaneously.
