[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. In the drawings, the same reference numerals indicate the same or corresponding technical features. The drawings are for illustrative purposes only and are not necessarily drawn to scale.

[0019] See Figure 1 , Figure 2 and Figure 3 As shown in the figure, a spot welding device for electronic chip processing includes: an operating table 1, a side plate 2 mounted on the upper left side of the operating table 1, an mounting plate 3 mounted on the upper right side of the side plate 2, a cylinder 4 mounted on the upper right side of the mounting plate 3, a laser welder 5 mounted on the lower end of the cylinder 4 through a piston rod passing through the lower end of the mounting plate 3, a spot welding vacuum adsorption stage 6 mounted on the upper end of the operating table 1 and below the laser welder 5, a dust extraction fan 7 installed on the left side of the inner cavity of the operating table 1, a dust extraction pipe 10 connected to the upper end of the dust extraction fan 7, a U-shaped pipe 20 connected to the right side of the dust extraction pipe 10, and the upper end of the U-shaped pipe 20 passing through the upper left side of the operating table 1 and connected to a conveyor belt. The conveying pipe 16 has a dust collection hood 17 connected to the front right side and the upper end of the conveying pipe 16 via a conduit. The dust collection fan 7 has a dust outlet pipe 8 connected to the right side. The dust outlet pipe 8 passes through the right side of the connecting plate 9. The lower and upper ends of the connecting plate 9 are fixed to the upper and lower ends of the inner cavity of the operating table 1. A collection frame 15 is provided at the lower right end of the connecting plate 9. A polyester non-woven fabric filter plate 11 is vertically provided on the right side of the connecting plate 9 and on the right side of the collection frame 15. A wood pulp fiber filter paper 12 is provided on the right side of the polyester non-woven fabric filter plate 11. An air outlet pipe 13 is provided on the right side of the operating table 1. An activated carbon adsorption filter plate 14 is provided in the inner cavity of the air outlet pipe 13.

[0020] Furthermore, a bracket is installed at the lower end of the vacuum cleaner 7, and the lower end of the bracket is connected and fixed to the left side of the lower end of the inner cavity of the operating table 1.

[0021] In this embodiment, the operator places the electronic chip to be welded on the spot welding vacuum adsorption stage 6, and then starts the cylinder 4, laser welder 5 and dust extraction fan 7 in sequence through the peripheral controller. The cylinder 4 drives the laser welder 5 to move up or down to weld and fix the electronic chip to be welded. A large amount of smoke or waste will be generated during welding.

[0022] Furthermore, support feet are welded around the lower end of the operating table 1, and anti-slip pads are attached to the lower end of the support feet.

[0023] In this embodiment, the dust extraction fan 7 simultaneously transports the fumes and flying debris generated during welding through the dust extraction pipe 10, U-shaped pipe 20, conveying pipe 16 and dust extraction hood 17 to one side of the connecting plate 9 inside the operating table 1 via the dust extraction pipe 8. Impurities and waste particles fall into the collection frame 15, and the airflow is filtered and blocked by the polyester non-woven filter plate 11 and the wood pulp fiber filter paper 12.

[0024] Furthermore, both sides of the front of the control panel 1 are equipped with hinged doors 19.

[0025] In this embodiment, the polyester nonwoven filter plate 11 has excellent fire resistance, which can effectively reduce the occurrence of fire accidents. It also has good high temperature resistance, making it suitable for spot welding filtration operations in high temperature environments. The internal fiber structure provides good filtration efficiency, which can capture tiny particles. The filtration accuracy can range from a few micrometers to several hundred micrometers.

[0026] Furthermore, both the upper and lower ends of the polyester nonwoven filter plate 11 and the wood pulp fiber filter paper plate 12 are provided with positioning grooves 18, and positioning blocks are slidably connected to the inner cavity of the positioning groove 18, and the outer side of the positioning block is fixed to the upper end of the inner cavity of the operating table 1.

[0027] In this embodiment, the wood pulp fiber filter paper 12 can intercept tiny particles such as dust, debris, and bacteria in the air, improve indoor air quality, and has a certain adsorption capacity to remove odors and harmful gases from the airflow. The filtered airflow is discharged after being filtered through the air outlet pipe 13 and the activated carbon adsorption filter plate 14.

[0028] Furthermore, the upper and lower ends of the polyester nonwoven filter plate 11 and the wood pulp fiber filter paper plate 12 are in contact with the upper and lower ends of the inner cavity of the operating table 1.

[0029] In this embodiment, the activated carbon adsorption filter plate 14 serves as a secondary filter for the airflow that needs to be discharged from the operating table 1, preventing impurities remaining in the airflow from being directly discharged and affecting the surrounding working environment. When the filter components need to be cleaned, the box door 19 can be opened to clean and maintain the components inside the operating table 1, and the waste collected in the collection box 15 can also be collected and cleaned in a unified manner.

[0030] During operation, the operator places the electronic chip to be welded on the spot welding vacuum adsorption table 6, and then sequentially starts the cylinder 4, laser welder 5, and dust extraction fan 7 via an external controller. The cylinder 4 drives the laser welder 5 to move up or down to weld and fix the electronic chip. Welding generates a large amount of smoke or debris. At the same time, the dust extraction fan 7 transports the smoke and flying debris generated during welding through the dust extraction pipe 10, U-shaped pipe 20, conveying pipe 16, and dust extraction hood 17 to one side of the connecting plate 9 inside the operating table 1 via the dust extraction pipe 8. Impurities and waste particles fall into the collection frame 15. The airflow is filtered and blocked by the polyester non-woven filter plate 11 and the wood pulp fiber filter paper 12. The polyester non-woven filter plate 11 has excellent fire resistance, which can effectively reduce the occurrence of fire accidents, and good high temperature resistance, making it suitable for high temperature environments. The spot welding filtration system utilizes an internal fiber structure that provides excellent filtration efficiency, capturing minute particles with a filtration precision ranging from a few micrometers to hundreds of micrometers. The wood pulp fiber filter paper 12 intercepts dust, debris, bacteria, and other tiny particles in the air, improving indoor air quality. It also possesses certain adsorption properties, removing odors and harmful gases from the airflow. The filtered airflow is then discharged after passing through the exhaust pipe 13 and the activated carbon adsorption filter plate 14. The activated carbon adsorption filter plate 14 serves as a secondary filter for the airflow that needs to be discharged from the operating table 1, preventing residual impurities in the airflow from being directly discharged and affecting the surrounding working environment. When cleaning the filter components is required, the cabinet door 19 can be opened to clean and maintain the components inside the operating table 1, and the debris collected in the collection frame 15 can also be collected and cleaned.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
