[0029] It should be noted that when the cleaning component 7 is in use, when the slide 4 slides between the two support frames 71, the motor five 74 and the motor six 77 are started, and the motor five 74 drives the screw five 73 to rotate, thereby driving the sliding seat 75 to move along the circular guide frame 72, thereby driving the hollow tube 76 to move. When moving, the brush 78 is driven to remove welding slag from the slide 4, and the motor six 77 drives the hollow tube 76 to rotate, thereby driving several brushes 78 to roll when moving to clean the slag, so as to more thoroughly clean the residue on the surface of the slide 4.

[0030] In the embodiments of the present invention, please refer to Figure 4 and Figure 5The other sliding seat 75 is embedded with an air duct 79, and an air fan 791 is embedded in the air duct 79. The air outlet end of the air duct 79 is connected to an air guide bend 792, and the air guide bend 792 is connected to the hollow tube 76. The outer wall of the hollow tube 76 is evenly provided with a number of air outlet holes 701.

[0031] It should be noted that when using the brush 78 for cleaning, the draft fan 791 is started simultaneously to blow air into the hollow tube 76 through the air guide bend 792, and then discharged from the air outlet 701 to further clean the residue on the slide 4.

[0032] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 A collecting box 8 is slidably mounted on the bottom end of the chip groove 102 .

[0033] It should be noted that: when the brush 78 is cleaning, it moves along the direction of the box chip groove 102 to clean, sweeping the residue into the chip groove 102, and then using the collection box 8 to collect it, which is convenient for unified transportation and processing later.

[0034] The working principle of the circuit board welding workbench provided by the utility model is as follows:

[0035] During use, the circuit board to be welded is positioned and placed on the table 41. At this time, the slide 4 is controlled to slide to the middle of the table 1, and then the motor 2 13 and the motor 3 52 are started to drive the screw 2 12 and the screw 3 51 to rotate respectively, thereby driving the support arm 5 to slide along the channel steel 11, and the suspension arm 53 to slide up and down along the support arm 5, and then the motor 4 65 of the welding assembly 6 is started to drive the screw 4 61 to rotate, thereby driving the suspension rod 62 to slide along the suspension arm 53, thereby driving the soldering iron 63 to move up and down and left and right for welding. The solder wire delivery pipe 64 is connected to the external solder wire delivery device. During welding, solder wire is continuously supplied to the welding part. The circuit board is removed after welding.

[0036] Or control motor 2 and motor 3, and move the support arm 5 and the suspension arm 53 out of the range of the platform 41. The staff holds the soldering iron 63 to perform soldering operation on the circuit board, and removes the circuit board after soldering.

[0037] The motor 13 is controlled to drive the screw 12 to rotate, thereby driving the slide 4 to slide along the slide groove 101 to one side of the cleaning component 7. When it slides to between the two support frames 71, the motor 5 74 and the motor 6 77 are started. The motor 5 74 drives the screw 5 73 to rotate, thereby driving the sliding seat 75 to move along the circular guide frame 72, thereby driving the hollow tube 76 to move. When moving (it is controlled to move in the opposite direction toward the chip discharge groove 102 each time it is cleaned, and the residue is swept into the chip discharge groove 102, and then collected by the collection box 8 for later unified transportation and processing), the brush 78 is driven to remove the welding slag from the slide 4. The motor 6 77 drives the hollow tube 76 to rotate, thereby driving several brushes 78 to roll when moving to clean the slag, so as to more thoroughly clean the residue on the surface of the slide 4.

[0038] Furthermore, the induced draft fan 791 is started synchronously to blow air into the hollow tube 76 through the air guide bend 792 and then discharged from the air outlet 701 to further clean the residue on the surface of the slide 4.
