[0031] Example 1

[0032] Reference Figure 1 - Figure 8 The present embodiment provides a laser cutting device for integrated circuit board production, including a laser cutting machine and a clamping assembly 100, wherein the clamping assembly 100 includes a substrate 101, a movable plate 102 connected to the substrate 101, a first transmission member 103 arranged at the upper end of the substrate 101, a second transmission member 104 cooperating with the first transmission member 103, a limit frame 105 fixedly connected to one side of the movable plate 102, and a pressing block 106 connected to the limit frame 105.

[0036] It should be noted that the first magnetic block 101b and the second magnetic block 102e are magnetically connected to ensure the stability of the device during the circuit board cutting process.

[0037] In addition, the handle 102f facilitates pushing the movable plate 102 to cut the circuit board.

[0038] Furthermore, the slide bar 102a includes a fixed block 102a-1 and a chain 102a-2, the fixed block 102a-1 is fixedly connected to one side of the slide bar 102a, and one end of the chain 102a-2 is fixedly connected to one side of the fixed block 102a-1.

[0039] Furthermore, the first transmission member 103 includes a first limiting sleeve 103a, a first sprocket 103b, an annular plate 103c and a first torsion spring 103d. The first limiting sleeve 103a is fixedly connected to the top of the base plate 101, one side of the first sprocket 103b is rotatably connected to the first limiting sleeve 103a, the annular plate 103c is fixedly connected to the top of the base plate 101, and the first torsion spring 103d is fixedly connected between the annular plate 103c and the other side of the first sprocket 103b.

[0041] Furthermore, the chain 102a - 2 is provided with a plurality of matching grooves 102a - 2a that engage with the first sprocket 103b and the second sprocket 104b, and the other end of the chain 102a - 2 is fixedly connected to the top of the pressing block 106 .

[0043] It should be noted that, during the process of the pressing block 106 being separated from the circuit board, the first spring 105 a is in a compressed state.

[0044] Furthermore, the pressing block 106 includes a through slot 106a, a shaft 106b and a rolling wheel 106c. The through slot 106a is provided at the bottom of the pressing block 106.

[0045] It should be noted that a rubber pad is sleeved on the circumferential surface of the rolling wheel 106 c , which can prevent the rolling wheel 106 c from making rigid contact with the circuit board, thereby providing a better protection effect on the circuit board.

[0046] When in use, first push the movable plate 102 through the handle 102f. When the sliding bar 102a at the bottom of the movable plate 102 slides on the slide 101a, the chain 102a-2 can be pulled through the fixed block 102a-1. The chain can drive the first sprocket 103b to rotate, and the first sprocket 103b drives the first torsion spring 103d to be compressed. At this time, the chain 102a-2 drives the pressing block 106 to rise through the second sprocket 104b. At this time, the first spring 105a is compressed, and then the circuit board to be cut is placed on the support plate 102b, and the movable plate 102 is reset backward until the first magnetic block 101b and the second magnetic block 102e are magnetically connected. At this time, the pressing block 106 can press the circuit board.

[0047] Example 2

[0048] Reference Figure 1 - Fig. 9 Based on the previous embodiment, this embodiment provides a laser cutting device for integrated circuit board production, wherein a connecting rod 102b-1 is fixedly connected to one side of the support plate 102b, the connecting rod 102b-1 slides in cooperation with the arc groove 102d, an inclined groove 102c-1 is provided at the connection between the baffle 102c and the support plate 102b, and a second torsion spring 102c-2 is fixedly connected between the baffle 102c and the movable plate 102.

[0049] It should be noted that the connecting rod 102b-1 and the arc groove 102d slide together, which can make the support plate 102b have better pressure resistance when the pressing block 106 presses the circuit board, and the second torsion spring 102c-2 is in a compressed state when the pressing block 106 presses the circuit board.

[0050] in addition, Figure 1 - Fig. 9 The structure in the figure is only used as a reference for mechanical transmission and is not a structural proportional diagram of the final product.

[0051] Furthermore, an elastic member 107 is provided on the movable plate 102, and the elastic member 107 includes a pop-up plate 107a, a ramp block 107b, a connecting shaft 107c and a second spring 107d. The pop-up plate 107a is slidably connected to a first groove opened on one side of the movable plate 102, and the ramp block 107b is slidably connected to a second groove opened on one side of the slide rod 102a. The first groove and the second groove are connected through a third groove. The connecting shaft 107c is fixedly connected between the pop-up plate 107a and the ramp block 107b, and the second spring 107d is fixedly connected between the connecting shaft 107c and the inner wall of the third groove.

[0052] It should be noted that when the movable plate 102 is pushed, the inclined surface of the inclined block 107b contacts the slide 101a and is gradually squeezed into the second groove, thereby driving the second spring 107d to be compressed. At this time, the pop-up plate 107a enters the first groove and will not affect the movement of the support plate 102b. When the movable plate 102 is reset, the second spring 107d is also reset. At this time, the pop-up plate 107a can pop out, thereby pushing the cut circuit board, so that the cut circuit board can better slide through the inclined groove 102c-1 to the collection device at the bottom.

[0053] When in use, first push the movable plate 102 through the handle 102f. When the slide bar 102a at the bottom of the movable plate 102 slides on the slide table 101a, the chain 102a-2 can be pulled through the fixed block 102a-1. The chain can drive the first sprocket 103b to rotate. The first sprocket 103b drives the first torsion spring 103d to compress. At this time, the chain 102a-2 drives the pressing block 106 to rise through the second sprocket 104b. At this time, the first spring 105a is compressed, and then the circuit board to be cut is placed on the support plate 102b, and the movable plate 102 is reset backward until the first magnetic block 101 b is magnetically connected to the second magnetic block 102e, and the pressing block 106 can press the circuit board. After the entire block is cut, continue to push the movable plate 102 forward. At this time, the rolling wheel 106b rolls on the circuit board, the pressing block 106 gradually rises, and the second torsion spring 102c-2 is reset, which can drive the support plate 102b to gradually tilt. At this time, since the circuit board is cut into two halves, due to the thrust of the pop-up plate 107a on the circuit board after reset, the circuit board will slide along the inclined surface of the inclined groove 102c-1. After the cutting is completed, the circuit board can slide along the inclined groove to the collection device, which has better practicality.

[0054] It should be noted that the movable plate 102 can be automatically pushed by connecting the electric telescopic rod to the handle 102f.
