[0006] The effects achieved by the above components are as follows: when using the moving device, the operator can manually control the sliding block to slide inside the chute, or manually control the sliding plate to slide on the top of the sliding block. Then, by placing the circuit board on the top of the sliding plate, the operator can well control any position of the circuit board to be set at the bottom of the spot welding head, which is convenient for welding the circuit board by the spot welding head, thus improving the welding efficiency of the circuit board to a certain extent.

[0007] Preferably, a round rod is fixedly connected to the inner wall of the chute, the round rod is slidably inserted through one side of the sliding block, and rubber sleeves are uniformly fixedly connected to the surface of the round rod.

[0008] The effects achieved by the above components are as follows: When the slider is slid to a suitable position on the surface of the round rod, the rubber sleeve is squeezed at the position where it contacts the inside of the slider and the round rod, thereby increasing a certain amount of friction, so that the slider can be fixed inside the chute.

[0009] Preferably, one side of the slider is fixedly connected with a first damping rod. The end of the first damping rod close to the slider is fixedly connected with one side of the sliding plate. A first spring is sleeved on the surface of the first damping rod.

[0012] The effects achieved by the above components are as follows: When the sliding plate is slid to a suitable position on the slider, the rectangular strip is squeezed away from the groove by the second spring, so that the rubber rod is squeezed against the bottom of the sliding plate, and thus the sliding plate is well fixed on the top of the slider.

The other end of the connecting rod is fixedly connected with a fixing plate. One side of the fixing plate is fixedly connected with a rubber strip, and small holes are uniformly formed in the top of the rubber strip.

[0016] The effects achieved by the above components are as follows: The circuit board is arranged on one side of the rubber arc block. The connecting rod is controlled to be close to one side of the connecting frame, so that the rubber strip is squeezed against one side of the rubber strip.

[0027] Example 1, as Figures 1-4 shown, a semi-automatic spot welder, the top of the operating table 1 is fixedly connected with a support frame 2, the top of the support frame 2 is fixedly connected with a cylinder 3, the output end of the cylinder 3 is provided with a spot welding head 4, one side of the support frame 2 is provided with an operating panel 5, the top of the operating table 1 is provided with a moving device 6, and the top of the moving device 6 is provided with a fixing device 7. When using the semi-automatic spot welder, the operator places the circuit board to be welded on the operating table 1, and drives the spot welding head 4 close to the circuit board through the cylinder 3, so as to weld the circuit board, which can achieve semi-automatic spot welding to a certain extent.

[0028] Refer to Figure 2 and Figure 3, the mobile device 6 includes a sliding block 602. A chute 601 is formed at the top of the operation table 1. The top of the chute 601 is slidably connected to the sliding block 602. The top of the sliding block 602 is slidably connected to a sliding plate 603. When using the mobile device 6, the sliding block 602 can be manually controlled to slide inside the chute 601, or the sliding plate 603 can be manually controlled to slide on the top of the sliding block 602. Then, by placing the circuit board on the top of the sliding plate 603, any position of the circuit board can be well controlled to be set at the bottom of the spot welding head 4, thus facilitating the welding of the circuit board by the spot welding head 4, which can improve the welding efficiency of the circuit board to a certain extent. A round rod 604 is fixedly connected to the inner wall of the chute 601. The round rod 604 slidably penetrates and is inserted into one side of the sliding block 602. Rubber sleeves 605 are evenly fixedly connected to the surface of the round rod 604. When the sliding block 602 is slid to a suitable position on the surface of the round rod 604, the rubber sleeves 605 are squeezed at the position where the sliding block 602 contacts the round rod 604 inside, thereby increasing a certain amount of friction force so that the sliding block 602 can be fixed inside the chute 601. A first damping rod 606 is fixedly connected to one side of the sliding block 602. One end of the first damping rod 606 close to the sliding block 602 is fixedly connected to one side of the sliding plate 603. A first spring 607 is sleeved on the surface of the first damping rod 606. The first spring 607 is fixedly connected to one side of the sliding block 602. One end of the first spring 607 close to the first damping rod 606 is fixedly connected to one side of the sliding plate 603. When the sliding plate 603 is not in use, the sliding plate 603 is pulled towards the sliding block 602 by the first spring 607, and then the sliding plate 603 can be arranged on the top of the sliding block 602. A groove 608 is formed at the top of the operation table 1. Second damping rods 609 are evenly fixedly connected to the inner wall of the groove 608. A rectangular strip 611 is fixedly connected to the top of the second damping rods 609. Rubber rods 612 are evenly fixedly connected to the top of the rectangular strip 611. A second spring 610 is sleeved on the surface of the second damping rods 609. One end of the second spring 610 is fixedly connected to one side of the inner wall of the groove 608. One end of the second spring 610 close to the second damping rod 609 is fixedly connected to the bottom of the rectangular strip 611. When the sliding plate 603 is slid to a suitable position on the sliding block 602, the rectangular strip 611 is squeezed away from the groove 608 by the second spring 610, so that the rubber rods 612 are squeezed against the bottom of the sliding plate 603, thus well fixing the sliding plate 603 on the top of the sliding block 602.

[0029] Refer to Figure 4, the fixing device 7 includes a support block 701. The support block 701 is fixedly connected to the top of the sliding plate 603. A connecting frame 703 is fixedly connected to the bottom of the sliding plate 603. When using the fixing device 7, the circuit board is arranged on one side of the support block 701 and the connecting frame 703, so that the circuit board can be well arranged on the top of the sliding plate 603. A rubber arc block 702 is fixedly connected to one side of the support block 701. A connecting rod 704 is slidably inserted into one side of the connecting frame 703. One end of the connecting rod 704 is fixedly connected to a fixing plate 705. A rubber strip 706 is fixedly connected to one side of the fixing plate 705. Small holes 707 are evenly formed in the top of the rubber strip 706. The circuit board is arranged on one side of the rubber arc block 702. The connecting rod 704 is controlled to approach one side of the connecting frame 703, and then the rubber strip 706 is pressed against one side of the rubber strip 706. Since the small holes 707 penetrate through the rubber strip 706, the deformation degree of the rubber strip 706 can be increased, and thus the circuit board can be well arranged on the top of the sliding plate 603. A third damping rod 708 is fixedly connected to one side of the connecting frame 703. The end of the third damping rod 708 away from the connecting frame 703 is fixedly connected to one side of the fixing plate 705. A third spring 709 is sleeved on the surface of the third damping rod 708. One end of the third spring 709 is fixedly connected to one side of the connecting frame 703. The end of the third spring 709 close to the third damping rod 708 is fixedly connected to one side of the fixing plate 705. The fixing plate 705 is pressed away from the connecting frame 703 by the third spring 709, so that the rubber strip 706 can be well pressed against one side of the circuit board. A rotating rod 710 is rotatably inserted into one side of the connecting frame 703. A clamping block 711 is fixedly connected to the end of the rotating rod 710 away from the connecting frame 703. The connecting rod 704 is manually pulled to make the connecting rod 704 away from the connecting frame 703, and then the rotating rod 710 is manually controlled on one side of the connecting frame 703, so that the clamping block 711 is arranged between one end of the connecting rod 704 and the connecting frame 703, and then the connecting rod 704 is clamped on the side away from the connecting frame 703, which is convenient for placing the circuit board on the top of the sliding plate 603.

[0030] Working principle: When using a semi-automatic electric welding machine, the operator manually places the circuit board to be welded on the operating table 1. The pneumatic cylinder 3 drives the spot welding head 4 to approach the circuit board, and then the circuit board can be welded, which can achieve semi-automatic spot welding to a certain extent. When using the moving device 6, the operator can manually control the sliding block 602 to slide inside the chute 601. When the sliding block 602 slides to a suitable position on the surface of the round rod 604, the rubber sleeve 605 squeezes the position where it contacts the round rod 604 inside the sliding block 602, thereby increasing a certain amount of friction, so that the sliding block 602 can be fixed inside the chute 601. The operator can also manually control the sliding plate 603 to slide on the top of the sliding block 602. When the sliding plate 603 slides to a suitable position on the sliding block 602, the second spring 610 squeezes the rectangular bar 611 away from the groove 608, so that the rubber rod 612 squeezes the bottom of the sliding plate 603, and thus the sliding plate 603 is well fixed on the top of the sliding block 602. Then, by placing the circuit board on the top of the sliding plate 603, the operator can well control the circuit board to be set at any position under the spot welding head 4, which is convenient for welding the circuit board by the spot welding head 4, and this can improve the welding efficiency of the circuit board to a certain extent. When using the fixing device 7, place the circuit board on one side of the support block 701 and the connecting frame 703, and on one side of the rubber arc block 702. The third spring 709 squeezes the fixing plate 705 away from the connecting frame 703, so that the rubber strip 706 can well squeeze one side of the circuit board. Since the small hole 707 penetrates the rubber strip 706, the deformation degree of the rubber strip 706 can be increased, and thus the circuit board can be well placed on the top of the sliding plate 603. When the circuit board needs to be placed, manually pull the connecting rod 704 so that the connecting rod 704 moves away from the connecting frame 703. Then, manually control the rotating rod 710 on one side of the connecting frame 703, and set the clamping block 711 in the middle of one end of the connecting rod 704 and the connecting frame 703, so that the connecting rod 704 is clamped on the side away from the connecting frame 703, which is convenient for placing the circuit board on the top of the sliding plate 603.
