When laminating a circuit board, four limit blocks can move closer to each other to limit the circuit board and prevent the phenomenon of the circuit board running during lamination processing. However, after specific use and comparison with the prior art, the following defects still exist:

[0004] Before laminating a multi-layer printed circuit board, the raw materials need to be stacked in pairs.

A limiting frame 26 is fixedly connected between the mutually remote sides of the gear plates 112. The mutually remote sides of the air bags 27 are fixedly connected to the inside of the limiting frame 26. The limiting frame 26 is used to limit the air bags 27 when they expand. Before the raw material 17 is pushed by the push plate 111, the air bags 27 can block the entrance of the sealing door 13, thereby reducing the loss of the temperature inside the box body 1 and keeping the temperature stable, which helps the raw materials 17 of each layer to be subjected to the same temperature during the lamination process and improves the lamination quality.

[0043] Reference Figures 10 to 12 As shown in the figure, there is a multi-layer printed circuit board laminating device. Fixed blocks 3 are fixedly connected to the mutually remote sides of the gear plates 112. Lifting blocks 31 are slidably connected to the upper surfaces of the bottoms of the fixed blocks 3.

[0044] Reference Figures 13 to 15 As shown, in a multi-layer printed circuit board lamination device, fixing rods 4 are symmetrically and fixedly connected to both sides of a limiting plate 110. Sliding plates 41 are slidably connected to the outer surfaces of the fixing rods 4. Screws 42 are threadedly connected to the tops of the sliding plates 41. Between the bottoms of adjacent screws 42 is threadedly connected to the upper surface of a baffle plate 18. The screws 42 are used to drive the baffle plate 18 to move up and down. Connecting springs 43 are fixedly sleeved on the outer surfaces of the fixing rods 4. The left ends of the connecting springs 43 are fixedly connected to the right sides of the sliding plates 41. The connecting springs 43 are used to drive the sliding plates 41 to move back to their original positions. Limiting blocks 44 are fixedly connected to the mutually remote sides of the fixing rods 4.

The mutually approaching ends of the return springs 46 are fixedly connected to the mutually remote sides of the limiting blocks 44. The return springs 46 are used to drive the restricting bars 45 to move back to their original positions. When the fixing rods 4 are rotated to drive the baffle plate 18 to move upward, the distance between the limiting plate 110 and the baffle plate 18 can be adjusted, enabling the limiting plate 110 to easily adapt to raw materials 17 of various thicknesses and specifications, so that there is no need to frequently replace the equipment or adjust the production line, which not only enhances the applicability of the equipment but also simplifies the operation process.

[0045] The complete working principle and steps of the above embodiments are as follows:

[0046] Reference Figures 1 to 5 As shown, when the circuit board lamination device is in the initial state, the servo motor 14 and the pushing motor 19 are in the off state, and the push plate 111 is threadedly connected to the outer surface of the right end of the lead screw 114;

[0047] When laminating a circuit board using this device, first, the operator places raw material 17 inside the limiting plate 110 and starts the servo motor 14. At this time, the output shaft of the servo motor 14 drives the switching plate 16 to rotate simultaneously through the switching frame 15. When the switching plate 16 rotates, it drives the limiting plate 110 to rotate simultaneously. After the mutually distant ends of the limiting plate 110 coincide with the entrance at the right end of the blocking plate 112, the output shaft of the pushing motor 19 drives the lead screw 114 to rotate simultaneously. When the lead screw 114 rotates, it drives the push plate 111 to move leftward. At this time, when the push plate 111 moves leftward on the outer surface of the limiting rod 113, the top on the left side of the push plate 111 will fit against the outer surface of the raw material 17 and push the raw material 17 leftward. The raw material 17 will slide from the inside of the limiting plate 110 to the upper surface on the mutually approaching side of the blocking plate 112, and then slide from the upper surface on the mutually approaching side of the blocking plate 112 into the interior of the box body 1, enabling the raw material 17 to be automatically stacked and placed quickly and accurately, achieving continuous operation.

[0048] When the pushing of the raw material 17 is completed, the output shaft of the pushing motor 19 drives the lead screw 114 to rotate in the reverse direction. When the lead screw 114 rotates in the reverse direction, it drives the push plate 111 to move rightward. When the push plate 111 moves rightward, the inclined surface of the push plate 111 will squeeze the outer surface of the raw material 17 and cause the raw material 17 to move upward, enabling the push plate 111 to move back to its original position.

[0049] When the push plate 111 moves back to its original position, the output shaft of the servo motor 14 can drive the switching plate 16 to rotate again through the switching frame 15. When the switching plate 16 drives the raw material 17 to rotate through the limiting plate 110, the raw material 17 can be replaced, enabling each layer of the raw material 17 to be accurately aligned and maintaining the consistency between each layer of the raw material 17, thereby improving the overall performance and reliability of the multi-layer printed circuit board after lamination.

[0050] Reference Figures 6 to 9 As shown, when the circuit board laminating equipment is in the initial state, the reset spring 21 is in a stretched state, and the airbag 27 is in an inflated state;

[0051] When the push plate 111 slides leftward, the right side of the push plate 111 will separate from the top on the right side of the extrusion rod 24. At this time, the reset spring 21 in the stretched state will drive the push rod 22 to slide leftward. When the push rod 22 slides leftward inside the cylinder 2, the gas inside the airbag 27 will enter the inside of the cylinder 2 through the air pipe 25. At this time, the airbag 27 will be in a contracted state, enabling the push plate 111 to smoothly slide into the interior of the box body 1.

[0052] As the push plate 111 slides to the right, the bottom on the right side of the push plate 111 will fit against the top on the left side of the extrusion rod 24 and drive the extrusion rod 24 to move to the right. When the extrusion rod 24 moves to the right, it will drive the push rod 22 to move simultaneously. When the push rod 22 moves to the right, it will cause the return spring 21 to return to the compressed state again. And when the push rod 22 slides to the right inside the cylinder 2, it can squeeze the air inside the cylinder 2 into the trachea 25. At this time, the gas can move from inside the trachea 25 to inside the airbag 27, so that the airbag 27 can return to the inflated state again. When the airbag 27 returns to the inflated state, it can block the entrance of the sealing door 13, thereby reducing the loss of the temperature inside the box body 1 and keeping the temperature stable, which helps the raw materials 17 on each layer to be subjected to the same temperature during the lamination process and improves the lamination quality.

[0053] Reference Figures 10 to 12 As shown, when the push plate 111 moves to the left, the bottom on the left side of the push plate 111 will fit against the right side of the closer ends of the lifting blocks 31 and cause the lifting blocks 31 to rotate towards the closer side. When the lifting blocks 31 rotate, they can rotate the torsion springs 32 to the energy storage state. As the push plate 111 continues to move to the left, the bottom on the left side of the push plate 111 will separate from the right side of the closer ends of the lifting blocks 31. At this time, the torsion springs 32 in the energy storage state will drive the lifting blocks 31 to move back. As the push plate 111 moves to the right, the arc surface at the bottom on the right side of the push plate 111 will fit against the inclined surface on the closer side of the lifting blocks 31. Since the left end on the farther side of the lifting blocks 31 fits against the right side of the fixed block 3, at this time, the lifting blocks 31 will be blocked by the fixed block 3, preventing the fixed block 3 from rotating towards the farther side. As the push plate 111 moves to the right, it drives the lifting blocks 31 to move upward. When the lifting blocks 31 move upward, they will cause the torsion springs 32 to move to the stretched state, and when the lifting blocks 31 move upward, they will squeeze the bottom of the raw material 17, causing the bottom of the raw material 17 to be lifted upward, so as to avoid the raw material 17 affecting the movement of the push plate 111 to the right, improve the stability and reliability of the push plate 111 during operation, and also prevent the raw material 17 from being damaged when the push plate 111 moves to the right, reduce the waste of the raw material 17, and lower the production cost.

[0054] When the arc surface of the push plate 111 separates from the inclined surface of the lifting blocks 31, the torsion springs 32 in the stretched state will drive the lifting blocks 31 to move downward, so that the raw material 17 can return to the initial state.

[0055] Reference Figures 13 to 15As shown, when the raw material 17 to be processed is relatively thick, the staff can rotate the screw 42 to drive the baffle 18 to move upward, increasing the distance between the baffle 18 and the limiting plate 110, so that the limiting plate 110 can easily adapt to raw materials 17 of various thicknesses and specifications. Thus, there is no need to frequently replace equipment or adjust the production line, which not only enhances the applicability of the equipment but also simplifies the operation process.

[0056] When the thickness of the raw material 17 exceeds the gap between the baffle 18 and the limiting plate 110, the staff can rotate the screw 42 in the reverse direction to disconnect the outer surface of the screw 42 from the upper surface of the baffle 18. Then, the staff can push the sliding plate 41 to the right. When the sliding plate 41 moves to the right on the outer surface of the fixed rod 4, it will cause the connecting spring 43 to move to the compressed state. When the sliding plate 41 moves, the outer surface on the right side of the sliding plate 41 will also squeeze the inclined surface of the limiting bar 45, causing the limiting bar 45 to move away from each other. When the limiting bar 45 moves, it will cause the return spring 46 to move to the stretched state. As the sliding plate 41 continues to move to the right, the right side of the sliding plate 41 will disengage from the inclined surface of the limiting bar 45. At this time, the return spring 46 in the stretched state will drive the limiting bar 45 to slide towards each other, enabling the limiting bar 45 to latch onto the sliding plate 41. At this point, the baffle 18 can be removed from between the outer surfaces of the limiting plate 110, allowing the limiting plate 110 to convey the raw material 17.

[0057] When the conveyance of the raw material 17 is completed, the staff can move the limiting bar 45 away from each other to disengage the inclined surface of the limiting bar 45 from latching onto the sliding plate 41. At this time, the connecting spring 43 in the compressed state will drive the sliding plate 41 to slide to the left. Thus, when the baffle 18 is lifted upward and the screw 42 is rotated, the screw 42 can re-control the up and down sliding of the baffle 18.
