The reinforcement component 2 is installed in the middle position of the lower end of the square plate 12, and the reinforcement component 2 is linked with the driving component 9. T-shaped plates 15 are fixedly installed on both sides of the L-shaped plate 6, and the purification component 3 is installed at the lower end of the T-shaped plate 15. An integrated control panel 16 is fixedly installed on one side of the L-shaped plate 6, and a CCD camera 17 is fixedly installed on one side of the lower end of the L-shaped plate 6. The CCD camera 17 is electrically connected to the integrated control panel 16. A sliding groove is opened at the upper end of the workbench 1, and a first bidirectional screw 19 driven by a first motor 18 is rotatably installed in the sliding groove. One end of the clamping plate 5 is threadedly connected to the first bidirectional screw 19, and the first motor 18 is connected to the integrated control The control panel 16 is electrically connected, the first electric guide rail and the second electric guide rail are both electrically connected to the integrated control panel 16, a circular groove is provided in the middle of one end of the limit plate 13, a damping telescopic rod 20 is fixedly installed in the circular groove, the free end of the damping telescopic rod 20 is fixedly connected to the buffer plate 14, a spring 21 is sleeved on the outside of the damping telescopic rod 20, one end of the spring 21 is fixedly installed in the circular groove, and the other end of the spring 21 is fixedly connected to the buffer plate 14, guide rods 22 are fixedly installed on both sides of one end of the buffer plate 14, and one end of the guide rod 22 is plugged into the limit plate 13. When in use, an electric soldering iron is installed on one side of the upper end of the L-shaped plate 6, and a conventional electric soldering iron can be used for welding.

The first motor 18 is electrically connected to the first plate 4, and the integrated control panel 16 can control the forward and reverse rotation of the first motor 18. First, manually place the mainboard on the upper end of the placement plate 4, and then start the first motor 18 through the integrated control panel 16 to drive the first bidirectional lead screw 19 to rotate, so that the clamping plates 5 on both sides move toward each other to fix the mainboard. Then, the driving component 9 is started through the integrated control panel 16 to move the limit plates 13 toward each other to fix electronic components of different sizes. At this time, the buffer plate 14 is in contact with the electronic component. When the electronic component is subjected to a large extrusion force, the buffer plate 14 drives the spring 21 to contract, and the damping telescopic rod 20 to contract. The generated deformation force is used to buffer the large extrusion force on the electronic component to prevent the excessive extrusion force from causing certain damage to the electronic component.At the same time, the reinforcement component 2 automatically absorbs and reinforces the electronic components to prevent the electronic components from shifting during the welding process and reducing the welding quality. The friction generated inside the damping telescopic rod 20 can offset the elastic potential energy generated by the spring 21 to prevent the buffer plate 14 from moving back and forth.

The integrated control panel 16 controls the first electric slide rail to move the sliding plate 7, and then controls the second electric slide rail to move the mounting plate 8. Then, the first cylinder 10 is started to move the square plate 12 downward to move the electronic component to the upper surface of the desired welding position. After the electronic component is moved to the specified position, it is manually soldered with an electric soldering iron. The operator does not need to manually position it, which improves the soldering efficiency. When too much exhaust gas is generated, the purification component 3 is manually started through the integrated control panel 16 to collect and purify the exhaust gas to prevent the exhaust gas from drifting into the air and causing certain damage to the operator's body.

[0030] The driving assembly 9 includes a second bidirectional lead screw 901 and a second motor 902. The second bidirectional lead screw 901 is rotatably installed in the square groove 11.

The integrated control panel 16 can control the second motor 902 to rotate forward and reverse. First, manually control the second motor 902 to start through the integrated control panel 16 to drive the second bidirectional lead screw 901 to rotate, so that the limit plate 13 moves toward each other inside the square groove 11, and electronic components of different sizes are clamped and fixed. When welding is completed, manually control the second motor 902 to rotate in the opposite direction through the integrated control panel 16, so that the limit plate 13 moves oppositely inside the square groove 11, and the fixing effect on the electronic components is released.

[0031] The reinforcement component 2 includes a suction cup 201, which is fixedly installed in the middle position of the lower end of the square plate 12, and square tubes 202 are fixedly installed on both sides of the upper end of the square plate 12. A piston 204 with a traction rod 203 installed at one end is slidably installed inside the square tube 202. One end of the square tube 202 is connected to the suction cup 201 through an air pipe 205. A sliding hole 206 is opened at the upper end of the square plate 12, and a moving plate 207 is symmetrically slidably installed in the sliding hole 206. One end of the moving plate 207 is fixedly connected to the limit plate 13, and the other end of the moving plate 207 is fixedly connected to the traction rod 203. When in use, when the second bidirectional screw 901 drives the limit plate 13 to move toward each other inside the square groove 11, the moving plate 20 7 then moves towards each other in the sliding hole 206, and the piston 204 is driven to move inside the square tube 202 through the traction rod 203, and the air inside the suction cup 201 is transported to the inside of the square tube 202 through the air supply pipe 205, so that the suction cup 201 automatically adsorbs and fixes the electronic components, so that the position of the electronic components will not be offset during the welding process, thereby improving the welding quality. When the welding is completed, the limit plate 13 drives the moving plate 207 to move in the opposite direction in the sliding hole 206, and the traction rod 203 moves in the opposite direction accordingly, so that the piston 204 moves inside the square tube 202, and the piston 204 is reset, and air is transported to the inside of the suction cup 201 through the air supply pipe 205, so as to release the adsorption and fixing effect of the suction cup 201 on the electronic components.

[0032] The purification component 3 includes a second cylinder 301 and a centrifugal fan 302. The second cylinder 301 is fixedly installed on one side of the lower end of the L-shaped plate 6.

An activated carbon adsorption plate 305 is inserted on one side of the adsorption box 304. When in use, a mounting frame is fixedly installed on the output end of the second cylinder 301. The air suction hood 303 is installed on the inner side of the mounting frame by bolts. When a lot of waste gas is generated during welding, the second cylinder 301 is manually controlled to start through the integrated control panel 16, and the air suction hood 303 is moved downward to a suitable position, and then The integrated control panel 16 starts the centrifugal fan 302, and the generated exhaust gas is transported to the inside of the adsorption box 304 through the suction hood 303 and the pipeline. The exhaust gas is purified by the activated carbon adsorption plate 305 inside the adsorption box 304 to remove harmful substances in the exhaust gas. The activated carbon can effectively adsorb harmful substances in the exhaust gas due to its large specific surface area and rich microporous structure. The purified gas is transported to the air inlet of the centrifugal fan 302 through the pipeline, and then transported to the external environment through the air outlet of the centrifugal fan 302. When the exhaust gas purification is completed, the centrifugal fan 302 is manually turned off through the integrated control panel 16, and the second cylinder 301 is started to reset the suction hood 303. When the activated carbon adsorption plate 305 needs to be replaced, the positioning screw is manually turned to release the fixing effect of the activated carbon adsorption plate 305, and then the activated carbon adsorption plate 305 is manually moved out of the adsorption box 304, and then a new activated carbon adsorption plate 305 is replaced.
