When the welding device 1 welds a product, a large amount of smoke is generated because different welding processes are adopted for a plurality of positions of the product in one process. If the smoke is scattered and then shooting is carried out, the welding efficiency is seriously influenced.

Meanwhile, the unadsorbed smoke dust can be scattered above the product, so that the product data shot by the camera shooting mechanism 8 is fuzzy, and the camera shooting mechanism cannot accurately calibrate the position of the product and check the condition of welding spots.

When the data of the product shot by the camera shooting mechanism 8 is in a fuzzy area, the camera shooting mechanism 8 sends a signal to increase the power of the seventh power device 93 and the power of the eighth power device 97. The seventh power device 93 rotates the second impeller 92 at an increased speed, and the flow rate of the air flow generated by the second impeller 92 along the plate body 94 is increased. The eighth power unit 97 increases the rotation speed of the third impeller 96, increases the flow speed of the air flow generated by the third impeller 96, increases the adsorption force formed at the lower end of the third adsorption cylinder 95, and allows the lower end of the third adsorption cylinder 95 to adsorb more air flow generated by the second impeller 92. Because the flow velocity of the airflow formed by the second adsorption mechanism 9 surrounding the product is relatively high, the atmospheric pressure at the position of the airflow is relatively low, the smoke and dust scattered above the product gradually approach to the airflow direction, and the smoke and dust can flow along with the airflow when contacting the airflow to complete recovery. The scattered smoke can be recovered in a shorter time.

The camera shooting mechanism 8 shoots the product before the product is welded, positions of welding points and positions of the product are marked in the photo data, the positions of the welding points and the positions of the product can be compared with the photo data shot in the subsequent welding process, when the shot photo data are found to be fuzzy, the camera shooting mechanism 8 sends signals to the seventh power device 93 and the eighth power device 97, the power of the seventh power device 93 and the power of the eighth power device 97 are increased, and the flow rate of airflow formed around the product is accelerated.

When the image data shot by the camera shooting mechanism 8 is calculated by an algorithm to find that the shot data of the product is not fuzzy any more, the camera shooting mechanism 8 sends signals to the seventh power device 93 and the eighth power device 97, and the power of the seventh power device 93 and the power of the eighth power device 97 return to the original values.

The camera 8 can transmit signals with different power increasing amplitudes to the seventh power device 93 and the eighth power device 97 according to the fuzzy degree of the picture data shot by the camera 8. When the degree of blur of the photograph data is heavy, the power of the seventh power unit 93 and the power of the eighth power unit 97 are increased by a large amount. When the degree of blur of the photograph data is light, the power of the seventh power unit 93 and the power of the eighth power unit 97 are increased by a small amount.

The seventh power device 93 drives the second impeller 92 to rotate, and the second impeller 92 generates airflow which passes through the avoiding holes on the supporting plate 4 and then flows along the plate body 94 from bottom to top. The eighth power device 97 drives the third impeller 96 to rotate, the third impeller 96 generates an air flow from bottom to top, an upward adsorption force is formed at the lower end of the third adsorption cylinder 95, the lower end of the third adsorption cylinder 95 adsorbs the air flow generated by the second impeller 92, and the air flow generated by the second impeller 92 flows between the third adsorption cylinder 95 and the plate body 94 and flows upward along the third adsorption cylinder 95 to complete the recovery.

The third pipe 82 is communicated with a cooling medium source, and the cooling medium is pumped by a water pump to complete the input of the cooling medium. The fourth pipe 83 recovers the cooling medium and needs to be cooled for recycling. A fan is disposed on the fourth pipe 83, and the fan is started to dissipate heat of the cooling medium flowing in the fourth pipe 83, and then the cooling medium in the fourth pipe 83 is returned to the cooling medium source.

Only one set of third conduits 82 and one set of fourth conduits 83 are needed to complete cooling of the weld head 13. Because the third pipeline 82 and the fourth pipeline 83 are communicated and arranged on the welding head 13 in a swinging mode at the position of the moving block 12, the swinging of the welding head 13 cannot drive the third pipeline 82 and the fourth pipeline 83 to move, and abrasion among the third pipeline 82, the fourth pipeline 83, the driving mechanism 2 and the welding device 1 is reduced.
