[0022] (3) This invention drives the connecting rod to move away from the purifier by moving the short plate away from the hinged rod. The connecting rod moves away from the purifier and contacts the trapezoidal plate. The purifier pushes the trapezoidal plate upward to prevent excessive harmful gases from being inhaled by operators after processing is completed, resulting in work-related accidents. At the same time, the upward movement of the rotating plate will cause the purifier to absorb the harmful gases that float to the top into the purifier to prevent harm caused by residual harmful gases.

The limit plate 18 is fixedly installed on the surface of the sliding seat 17 to prevent the vibration generated during the processing from causing the circuit board to shake up and down, affecting the equipment processing.

[0033] The limit plate 18 is arranged above the connecting plate 11, a No. 1 spring is arranged between the sliding seat 17 and the slide groove, and the sliding seat 17 is reset by the No. 1 spring, and a No. 1 torsion spring is arranged between the hinge rod 16 and the fixed block 15, and the hinge rod 16 is reset by the No. 1 torsion spring.

[0034] A method for using a PCB circuit board fusing device comprises the following steps:

[0035] Step 1: The output end of the electric push rod 9 moves toward the bottom of the fusion device 8 to drive the fixed plate 10 to approach the bottom of the fusion device 8, and the fixed plate 10 moves toward the bottom of the fusion device 8 to drive the sliding rod 12 to approach the bottom of the fusion device 8;

[0036] Step 2: The sliding rod 12 drives the clamping plate 14 to move closer to the bottom of the fusion device 8, and the circuit board is clamped by the clamping plate 14 to prevent the fusion device 8 from moving during the processing and affecting the normal processing of the device;

[0037] Step 3: Use the reciprocating screw rod 4 to rotate and drive the spiral block 5, the electric telescopic rod 6 and the fusion head to move back and forth, so as to adjust the processing position and improve the working effect;

[0038] Step 4: The sliding seat 17 moves downward to drive the limit plate 18 to move downward. The limit plate 18 moves downward to limit the circuit board to prevent the vibration generated during the processing from causing the circuit board to shake up and down and affect the equipment processing.

[0039] When the present embodiment is working, the output end of the electric push rod 9 moves toward the bottom of the fusion device 8 to drive the fixed plate 10 to approach the bottom of the fusion device 8. The fixed plate 10 approaches the bottom of the fusion device 8 and drives the sliding rod 12 to approach the bottom of the fusion device 8. The sliding rod 12 approaches the bottom of the fusion device 8 and drives the clamping plate 14 to approach the bottom of the fusion device 8.

At the same time, the reciprocating screw rod 4 is used to rotate to drive the spiral The block 5, the electric telescopic rod 6 and the fusion head move back and forth, which can adjust the processing position and improve the working effect. At the same time, when the clamp 14 is clamped to the circuit board, the reverse force will push the clamp 14 to move toward the fixed plate 10. The movement of the clamp 14 toward the fixed plate 10 will cause the sliding seat 17 to be pulled by the hinged rod 16. The hinged rod 16 will cause the sliding seat 17 to move downward. The downward movement of the sliding seat 17 will drive the limit plate 18 to move downward. The downward movement of the limit plate 18 will limit the circuit board to prevent the vibration generated during the processing from causing the circuit board to shake up and down, affecting the equipment processing.

[0044] A rotating plate 208 is rotatably installed on the inner wall of the air intake port 202, an L-shaped plate 209 is fixedly installed on the top of the rotating plate 208, a pull rope 2010 is fixedly installed on the top of the sealing slide 205, and one end of the pull rope 2010 away from the sealing slide 205 is fixedly installed on the top of the L-shaped plate 209.

[0046] When this embodiment is working, the push rod 194 is driven to rotate downward by the hinge rod 16, and the push rod 194 is driven to rotate downward by the hinge rod 16. The downward rotation of the push rod 194 pushes the correction plate 193 to move away from the hinge rod 16. The movement of the correction plate 193 away from the hinge rod 16 will correct the circuit board to prevent position displacement during processing, which will cause unqualified processing. At the same time, the movement of the correction plate 193 away from the hinge rod 16 will drive the short plate 195 to move away from the hinge rod 16. The movement of the short plate 195 away from the hinge rod 16 will push the push plate 197 to rotate. The rotation of the push plate 197 will drive the turntable 196 to rotate. The rotation of the turntable 196 will drive the support plate 198 to rotate. The rotation of the support plate 198 will support the bottom of the circuit board. The supporting bottom can effectively disperse the stress generated during the clamping process, reduce the local stress concentration of the circuit board, and reduce the risk of deformation or damage of the board.

[0047] The short plate 195 moves away from the hinge rod 16, driving the connecting rod 203 to move away from the purifier 201. The connecting rod 203 moves away from the purifier 201 and contacts the trapezoidal plate 207. The purifier 201 pushes the trapezoidal plate 207 to move upward. The upward movement of the trapezoidal plate 207 drives the long rod 206 to move upward. The upward movement of the long rod 206 drives the sealing slide 205 to move upward.

When there are too many harmful gases, the operators may inhale the harmful gases, causing work-related accidents. At the same time, when the processing is completed, the equipment resets the sealing slide 205 to move downward to block the air inlet 202 to prevent the harmful gases inside the purifier 201 from leaking out, posing a safety hazard. At the same time, the upward movement of the sealing slide 205 will drive the pull rope 2010 to move upward, and the upward movement of the pull rope 2010 will pull the L-shaped plate 209 to move upward. The upward movement of the L-shaped plate 209 will drive the rotating plate 208 to move upward. The upward movement of the rotating plate 208 will cause the purifier 201 to absorb the harmful gases that float to the top into the purifier 201 to prevent the residual harmful gases from causing harm.

A PCB circuit board fusing device according to claim 2, Features: A rotating plate (208) is rotatably mounted on the inner wall of the air inlet (202), an L-shaped plate (209) is fixedly mounted on the top of the rotating plate (208), a pull rope (2010) is fixedly mounted on the top of the sealing slide plate (205), and one end of the pull rope (2010) away from the sealing slide plate (205) is fixedly mounted on the top of the L-shaped plate (209).

4. A PCB circuit board fusing device according to claim 3, Features: The connecting rod (203) is in surface contact with the trapezoidal plate (207), a No. 2 spring is provided between the sealing slide plate (205) and the air inlet (202), a No. 3 torsion spring is provided between the air inlet (202) and the rotating plate (208), and the sealing plate (204) is in surface contact with the sealing slide plate (205).

5. A method for using a PCB circuit board fusing device, using the PCB circuit board fusing device according to claim 4, It is characterized in that The following steps are involved: Step 1: The output end of the electric push rod (9) moves toward the bottom of the fusion device (8) to drive the fixed plate (10) to approach the bottom of the fusion device (8); the fixed plate (10) moves toward the bottom of the fusion device (8) to drive the sliding rod (12) to approach the bottom of the fusion device (8); Step 2: The sliding rod (12) drives the clamping plate (14) to move closer to the bottom of the fusion device (8), and the clamping plate (14) clamps the circuit board to prevent the fusion device (8) from moving during the processing, thereby affecting the normal processing of the device; Step 3: The reciprocating screw rod (4) is used to rotate and drive the spiral block (5), the electric telescopic rod (6) and the fusion head to move back and forth, so as to adjust the processing position and improve the working effect; Step 4: The sliding seat (17) moves downward to drive the limit plate (18) to move downward. The limit plate (18) moves downward to limit the circuit board to prevent the vibration generated during the processing from causing the circuit board to shake up and down, thereby affecting the equipment processing.
