DETAILED DESCRIPTION

[0018] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0019] A multi-layer circuit board assembly auxiliary device, such as Figure 1-Figure 3As shown, it includes a placement plate 1, an electric push rod 3, a connecting rod 4, a connecting seat 5, a sliding plate 6, a first spring 7 and a pre-stressing assembly. Four electric push rods 3 are connected to the lower middle side of the placement plate 1. The telescopic ends of the electric push rods 3 are connected to connecting rods 4. The upper sides of the connecting rods 4 are connected to connecting seats 5. The connecting seats 5 are all slidably connected to the placement plate 1. The connecting seats 5 are all slidably connected to the sliding plates 6. Two first springs 7 are connected between the sliding plates 6 and the connected connecting seats 5. A pre-stressing assembly is provided on the placement plate 1.

[0020] like Figure 1 As shown, the pre-pressing assembly includes a trackless cylinder 10, a sliding rod 11, a sliding member 12, a screw 13, a lifting frame 14, a second spring 15 and a pressure wheel 16. The left and right upper sides of the placement plate 1 are connected to the trackless cylinder 10, the sliding rod 11 is connected between the sliders of the trackless cylinder 10, the left and right parts of the sliding rod 11 are slidably connected to the sliding member 12, the sliding member 12 is threadedly connected with the screw 13, the upper side of the screw 13 is provided with a knob for easy rotation, the lower side of the screw 13 is in contact with the sliding rod 11, the sliding member 12 is slidably connected to the lifting frame 14, the upper side of the lifting frame 14 is provided with a limit block for limiting the moving range of the lifting frame 14, the front and rear parts of the lifting frame 14 are connected to the second spring 15 between the adjacent sliding members 12, and the lower side of the lifting frame 14 is rotatably connected to the pressure wheel 16.

[0021] like Figure 2 As shown, it also includes a footing 2, and the lower sides of the left and right parts of the placement plate 1 are connected to two front and rear footings 2.

[0022] like Figure 2 As shown, it also includes fixing parts 8 and driving cylinders 9. Four fixing parts 8 are connected to the lower side of the placement plate 1. The fixing parts 8 are all connected to the driving cylinders 9. The telescopic ends of the driving cylinders 9 all pass through the placement plate 1.

[0023] When using the utility model, first place the placement plate 1 in the multi-layer circuit board assembly area, support the placement plate 1 through the base 2, and then place the circuit layers on the placement plate 1 layer by layer. After placement, start the electric push rod 3 to drive the connecting rod 4 to move, so that the connecting seat 5 and the sliding plate 6 move inward to contact the circuit layer, and align the circuit layer. Then, loosen the screw 13 through the knob to adjust the position of the sliding member 12. After the adjustment, loosen the screw 13 to fix the position of the sliding member 12, and then start the trackless cylinder 10 to make the slider drive the sliding rod 11 to move backward, so that the sliding member 12 moves backward, and then the pressure wheel 16 moves on the circuit layer. At this time, the lifting frame 14 moves upward, and the second spring is used to release the lifting frame 14. The force of the spring 15 keeps the pressure wheel 16 in contact with the circuit layer at all times, thereby pre-pressing the circuit layer to reduce the stress between the circuit layers and the risk of warping and twisting of the circuit board. After the pressure wheel 16 is separated from the circuit layer, the placement plate 1 is moved to the bottom of the laminator to move the laminate downward, pressing the sliding plate 6 to move downward, and the first spring 7 is squeezed and contracted to press the laminate down on the circuit layer to laminate the circuit layer. After lamination, the placement plate 1 is no longer located under the laminator, and the first spring 7 rebounds to push the sliding plate 6 to reset, and then the driving cylinder 9 on the fixing part 8 is started to extend the telescopic end of the driving cylinder 9 to push the circuit layer upward to facilitate the removal of the circuit layer.
