Description

Technical Field

[0001] The present invention relates to the technical field of printed circuits, and in particular to a reinforcing steel sheet laminating device and a reinforcing steel sheet laminating method. Background Art

[0002] The reinforcing steel sheet is usually made of thin steel and has the characteristics of high strength and flexibility. Its function is to increase the mechanical strength and stability of the FPC and prevent the FPC from bending, breaking or deforming during use. The reinforcing steel sheet usually exists in the form of a narrow strip and can be fixed to the FPC by bonding or attaching. It can be attached to one or both sides of the FPC to increase the rigidity and stability of the entire circuit board.

[0003] The reinforcing steel sheet bonding device is to bond the reinforcing steel sheet to the FPC. In the related technology, the reinforcing steel sheet on the material strip is first peeled off to the top surface of the material table. Since there are multiple reinforcing steel sheets in the same row on the material strip, there are multiple steel sheets on the top surface of the material table at this time; the bonding device moves the vacuum suction cup to the top surface of the material table, drives the vacuum suction cup to descend, and the vacuum suction cup absorbs one of the reinforcing steel sheets, and then moves the vacuum suction cup to the top of the workbench where the FPC is placed, and the vacuum suction cup bonds the reinforcing steel sheet to the surface of the FPC to complete the bonding of the reinforcing steel sheets; then the vacuum suction cup is driven to absorb the next reinforcing steel sheet, and the vacuum suction cup repeatedly circulates to attach the reinforcing steel sheet to the surface of the FPC.

[0004] With respect to the above-mentioned related technologies, in the process of transferring the reinforcing steel sheet by the vacuum suction cup, the vacuum suction cup is moved to the material table, and after the vacuum suction cup absorbs the reinforcing steel sheet, the vacuum suction cup is moved to the workbench, and the vacuum suction cup attaches the reinforcing steel sheet to complete the attachment of one reinforcing steel sheet; the above-mentioned operation is repeated, and each time a reinforcing steel sheet is attached, the vacuum suction cup needs to be moved to the material table. Such reciprocating motion makes the transfer efficiency of the reinforcing steel sheet low, which further causes the low efficiency of FPC attaching the reinforcing steel sheet.

[0026] S9. Repeat S8 to complete the attachment of all reinforcing steel sheets on the adsorption head.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. When it is necessary to adsorb the compensation steel sheet on the material table, the first driving mechanism drives the mobile frame to move above the material table, the cylinder drives the lifting frame to descend, the descent of the lifting frame drives the rotary motor to descend, the rotary motor drives the installation box to descend, the installation box drives the four installation blocks to descend, the installation blocks drive the adsorption head to descend, and the four adsorption heads adsorb the four reinforcing steel sheets on the top of the material table at the same time; the cylinder drives the adsorption head to rise again, the first driving mechanism drives the mobile frame to move above the workbench, the driving component first drives one adsorption head to descend, so that the height of the reinforcing steel sheet adsorbed by the adsorption head is lower than the other three reinforcing steel sheets, the lower reinforcing steel sheet is aligned with the position of the FPC that needs to be reinforced, and finally the cylinder drives the adsorption head Descend, attach the lowest reinforcement steel sheet to the FPC surface, and release the adsorption of the reinforcement steel sheet by the adsorption head; then the driving component drives the lower adsorption head to rise to its original position, and drives all adsorption heads to rise at the same time, and drives another adsorption head to descend, and moves the adsorption head to align the lowest reinforcement steel sheet with the next position of the FPC that needs to be reinforced, and then drives all adsorption heads to descend, so that the lowest reinforcement steel sheet is attached to the FPC reinforcement position, and then reciprocates in this way to attach four reinforcement steel sheets, reducing the time for the adsorption head to move to the material table to absorb the reinforcement steel sheet, improving the transportation efficiency of the reinforcement steel sheet, and further improving the efficiency of FPC attaching the reinforcement steel sheet;

[0029] 2. When it is necessary to drive the suction head to descend, the driving motor drives the rotating shaft to rotate, and the rotating shaft drives the four cams to rotate simultaneously; when the raised part of one of the cams contacts the baffle, the raised part of the cam presses down the baffle, and the baffle presses down the first spring and the slide bar, and the slide bar drives the suction head to descend until the suction head descends to the lowest position, and the driving motor stops driving the rotating shaft to rotate, so that the lowest reinforcing steel sheet can be attached; then the driving motor drives the rotating shaft to rotate 60° to release the downward pressure of the cam on the baffle, and the baffle, pushed by the first spring, drives the suction head to rise through the slide bar, so that the suction head returns to its original position, and at this time, the other suction head moves to the lowest position with the cam pressing down the baffle; and so on, so that the four suction heads move to the lowest position in turn;

[0030] 3. When the stripping shaft cooperates with the stripping plate to strip the reinforcing steel sheet, the stripping plate first strips the deformed end of the reinforcing steel sheet. Since the belt pulls the reinforcing steel sheet downward, the lower pressure shaft presses down on the other end of the reinforcing steel sheet, making it difficult for the reinforcing steel sheet to be pulled up by the belt, and the stripped end of the reinforcing steel sheet can enter the top surface of the stripping plate, thereby improving the stability of the stripping table in stripping the reinforcing steel sheet.
