The input end of the upper adsorption channel 72 is aligned with and connected to the output end of the lower adsorption channel 71.

[0048] Through the arrangement of the above structure, when the cover shell 2 is fitted with the base 1, the upper adsorption channel 72 and the lower adsorption channel 71 will be connected. At this time, the negative pressure in the welding cavity will be transmitted to the adsorption groove 7, thereby adsorbing and fixing the lower base, effectively improving the stability of welding.

[0049] Reference Figure 1-Figure 9In the present invention, when in use, the two substrates constituting the water-cooling plate are aligned and laid flat on the base 1, and then the first cylinder 21 is turned on to pull the cover 2 downward to fit the top of the base 1, thereby forming a sealed welding cavity; then the second cylinder 23 pushes the negative pressure suction cup 24 to move downward and fit the upper substrate, and then the negative pressure suction cup 24 is turned on to adsorb and fix the upper substrate, and the second cylinder 23 moves upward to an appropriate height and then stops, at which time a clean space will be formed between the upper substrate and the lower substrate. The driving motor 332 is then turned on to drive the dust collecting blade 331 to rotate in the dust collecting box 33. At this time, a thrust will be generated on the side close to the exhaust pipe 36, so that the airflow will enter the exhaust groove 353 along the exhaust pipe 36. At this time, due to the repulsive effect between the first magnetic plate 354 and the blocking plate 352, the blocking plate 352 will be pushed back to the air guide groove 313, so that the exhaust hole 351 is in a state of communication with the exhaust groove 353. At this time, the airflow will enter the air guide groove along the exhaust hole 351 313, and then enters the power box 37 along the air guide groove 313 and the exhaust box 35 to drive the driving impeller 371 to rotate, so that the reciprocating screw 311 rotates, thereby making the sliding plate 3 move along the reciprocating screw 311, and the first magnetic plate 354 will continue to repel the blocking plate 352 at different positions subsequently, so as to ensure that the airflow continuously enters the power box 37 to drive the driving impeller 371 to rotate, and ensure the smooth movement of the sliding plate 3, and when the sliding plate 3 moves to the cleaning cavity, the laser cleaning head 32 is turned on to emit a laser beam to interact with the surface of the substrate, so as to clean the bonding surfaces of the two substrates, ensure the cleanliness of the substrate, improve the welding effect and the production quality of the water-cooled plate; at the same time, a suction effect will be generated on the side close to the dust suction pipe 34, and this suction effect will be transmitted to the cleaning cavity through the dust suction hole 341, so as to absorb the debris and impurities generated during the cleaning process, avoid the debris from adhering to the substrate again, and ensure the cleanliness of the welding cavity.

[0050] In the process of driving the impeller 371 to rotate, the repulsive effect of the third magnetic plate 63 and the piston plate 61 is utilized. When the two are in the repulsive area, the piston plate 61 will be pushed to move toward the side of the compressed third spring 62, thereby compressing the gas in the gas chamber 6 and opening the one-way valve in the gas pipe 64, so that the gas in the gas chamber 6 enters the gas storage ring 51 along the gas pipe 64. When the third magnetic plate 63 and the piston plate 61 are separated from the repulsive area, the piston plate 61 will return to its original position and slide under the rebound effect of the third spring 62, thereby generating a suction effect in the gas chamber 6, thereby opening the one-way valve in the exhaust pipe 66, so that the gas in the welding cavity is sucked into the gas chamber 6 for replenishment, and utilizing the design of the nitrogen molecule filtration membrane. The arrangement will only allow the nitrogen component in the air to enter the air storage ring 51, thereby continuously increasing the air pressure in the air storage ring 51 and continuously reducing the air pressure in the welding cavity, and the airflow entering the power box 37 will eventually be discharged to the outside from the air outlet pipe 372, thereby comprehensively reducing the original gas in the welding cavity. First, the welding cavity will gradually approach a vacuum state, thereby avoiding the influence of oxygen, hydrogen, etc. on welding (such as oxidation), thereby improving the welding quality; secondly, when the cover shell 2 is fitted with the base 1, the upper adsorption channel 72 and the lower adsorption channel 71 will be connected. At this time, the negative pressure in the welding cavity will be transmitted to the adsorption groove 7, thereby adsorbing and fixing the lower base, effectively improving the stability of welding.

[0051] When the cleaning is completed, the second cylinder 23 pushes the upper substrate downward to make it fit with the lower substrate, and then the internal brazing raw material is melted by the hot melt tank 432, and then the welding tube 433 is adjusted to a suitable height by controlling the electric push rod 431, and then the driving motor 421 and the electromagnetic valve in the welding tube 433 are turned on at the same time, the driving motor 421 will drive the belt 422 to rotate, and the sliding seat 41 will move along the annular slide rail 4 by friction, and after the electromagnetic valve in the welding tube 433 is opened, the hot-melted brazing liquid will drip out, so as to braze the connection between the upper substrate and the lower substrate, and at the same time, the second magnetic plate 522 and the sealing The repulsive effect of the plate 512 will push the sealing plate 512 to move into the gas storage ring 51 when the sliding seat 41 slides to each gas outlet groove 511, so that the gas outlet groove 511 is connected with the gas guide bin 521. At this time, the nitrogen stored in the gas storage ring 51 will be discharged to the weld along the blow pipe 54, so as to first push the brazing liquid into the weld quickly and effectively, so that the brazing liquid can achieve better penetration effect, and also accelerate the gas flow speed at the weld, so that the brazing liquid can be quickly condensed, thereby effectively improving the welding efficiency and quality; finally, when the sliding seat 41 rotates one circle, the above-mentioned welding operation can be stopped, and then the cover shell 2 can be opened to take out the finished water-cooled plate after welding.

[0052] Embodiment 2:

[0053] Reference Figure 1-Figure 9 , which is basically the same as the first embodiment, on the basis of the first embodiment, a welding method of a water cooling plate is proposed, and the steps are as follows:

[0054] Step 1, first clean the two substrates that make up the water-cooled plate: turn on the drive motor 332 to drive the dust suction blade 331 to rotate in the dust suction box 33, and at this time, a thrust will be generated on the side close to the exhaust pipe 36, so that the airflow will enter the exhaust groove 353 along the exhaust pipe 36. At this time, due to the repulsive effect between the first magnetic plate 354 and the blocking plate 352, the blocking plate 352 will be pushed back to the air guide groove 313, so that the exhaust hole 351 is in a state of communication with the exhaust groove 353. At this time, the airflow will enter the air guide groove 313 along the exhaust hole 351, and then enter the power box 37 along the air guide groove 313 and the exhaust box 35 to push the driving impeller 371 to rotate, so that the reciprocating screw rod 311 rotates, thereby causing the sliding plate 3 to move along the reciprocating screw rod 311. The first magnetic plate 354 will continue to repel the blocking plates 352 at different subsequent positions, thereby ensuring that the airflow continuously enters the power box 37 to drive the driving impeller 371 to rotate, thereby ensuring the smooth movement of the sliding plate 3. When the sliding plate 3 moves to the cleaning cavity, the laser cleaning head 32 is turned on to emit a laser beam to interact with the surface of the substrate, thereby cleaning the fitting surfaces of the two substrates, ensuring the cleanliness of the substrates, improving the welding effect and the production quality of the water-cooled plate; at the same time, suction will be generated on the side close to the dust suction pipe 34, and this suction will be transmitted to the cleaning cavity through the dust suction hole 341, thereby absorbing the debris and impurities generated during the cleaning process, preventing the debris from adhering to the substrate again, thereby ensuring the cleanliness of the welding cavity.

[0055] Step 2, exhaust the air in the cavity formed by the base 1 and the cover shell 2: in the process of driving the impeller 371 to rotate, the repulsive effect of the third magnetic plate 63 and the piston plate 61 is utilized. When the two are in the repulsive area, the piston plate 61 will be pushed to move toward the side of the compressed third spring 62, thereby compressing the gas in the gas chamber 6 and opening the one-way valve in the gas filling pipe 64, so that the gas in the gas chamber 6 enters the gas storage ring 51 along the gas filling pipe 64. When the third magnetic plate 63 and the piston plate 61 are separated from the repulsive area, the piston plate 61 will return to its original position and slide under the rebound effect of the third spring 62, thereby generating a suction force in the gas chamber 6. Use, thereby opening the one-way valve in the exhaust pipe 66, so that the gas in the welding cavity is sucked into the charging chamber 6 for replenishment, and by utilizing the setting of the nitrogen molecule filter membrane, only the nitrogen component in the air will enter the gas storage ring 51, thereby continuously increasing the air pressure in the gas storage ring 51, and continuously reducing the air pressure in the welding cavity, and the airflow entering the power box 37 will eventually be discharged to the outside from the air outlet pipe 372, thereby comprehensively reducing the original gas in the welding cavity. First, the welding cavity will gradually approach a vacuum state, thereby avoiding the influence of oxygen, hydrogen, etc. on welding, thereby improving the welding quality.

[0056] Step 3, weld the connection between the two substrates and process the weld: melt the brazing raw material inside the hot melt tank 432, then adjust the welding tube 433 to a suitable height by controlling the electric push rod 431, and then turn on the drive motor 421 and the solenoid valve in the welding tube 433 at the same time, the drive motor 421 will drive the belt 422 to rotate, and the sliding seat 41 will move along the annular slide rail 4 by friction, and after the solenoid valve in the welding tube 433 is opened, the hot-melt brazing liquid will drip out, so as to weld the connection between the upper substrate and the lower substrate. Brazing is performed. At the same time, by utilizing the repulsive effect between the second magnetic plate 522 and the sealing plate 512, when the sliding seat 41 slides to each air outlet groove 511, the sealing plate 512 will be pushed to move into the air storage ring 51, so that the air outlet groove 511 is connected with the air guide bin 521. At this time, the nitrogen stored in the air storage ring 51 will be discharged to the weld along the blowing pipe 54, so as to firstly push the brazing liquid into the weld quickly and effectively, so that the brazing liquid can achieve better penetration effect, and can also accelerate the gas flow speed at the weld, so that the brazing liquid can condense quickly, thereby effectively improving the welding efficiency and quality.
