[0002] Flexible printed circuits (FPCs), also known as flexible printed circuits or flexible printed circuit boards, are highly sought after for their lightweight, thin, and flexible bendable and foldable properties. With the rapid development of the electronics industry, circuit board designs are increasingly demanding higher precision and higher density. Traditional manual inspection methods are no longer sufficient to meet production demands, and automated FPC defect detection is becoming an inevitable trend in the industry. These flexible printed circuits can be bent and folded freely, are lightweight, compact, have excellent heat dissipation, and are easy to install, revolutionizing traditional interconnect technology. The materials used in flexible circuits are insulating films, conductors, and adhesives.

[0077] The application provides a material moving mechanism of a high-efficiency laminating machine, which has a PI film to be taken (a base film is arranged below the PI film and used for supporting the PI film to move) on one side of the equipment and a FPC to be laminated on the other side, and the PI film and the FPC are parallel and have the same height.

[0078] When the PI film is attached to the FPC, the two mobile boxes 3 are in the lowest state, wherein the negative pressure tube 4 of the mobile box 3 on one side generates negative pressure and adsorbs the PI film; the negative pressure in the negative pressure tube 4 of the mobile box 3 on the other side disappears, and the PI film on the mobile box 3 is attached to the FPC; after the attachment is completed, the lifting and rotating mechanism drives the connecting arm 2 and the two mobile boxes 3 to rise, so that the PI film is separated from the base film, and the FPC with the film is in a free state; then the lifting and rotating mechanism drives the connecting arm 2 to rotate 90 degrees. At the same time, the base film of the PI film moves forward one station, so that the next PI film is put into the standby state, and the FPC film is pulled forward, so that the next FPC to be pasted moves to the substitute film pasting station; then the connecting arm 2 rotates 90 degrees and drops down. At this time, the mobile net box 3 with the PI film is pasted, and the empty mobile net box 3 to which the PI film has been pasted absorbs the new PI film. This reciprocating process can make the film pasting efficient; the connecting arm 2 rotates counterclockwise and clockwise in sequence, rather than rotating in only one direction.

[0079] When the connecting arm 2 is in the second state, the two shooting components located above shoot the PI film and FPC respectively, where the purpose of shooting the PI film is to obtain accurate data on the position of the PI film, and the purpose of shooting the FPC is to obtain accurate data on the position of the FPC; at the same time, the two shooting components located below respectively obtain accurate data on the empty mobile network box 3 and the mobile network box 3 with PI film; then after the above four groups of data are transmitted to the controller, the controller controls the operation of two groups of UVW platforms 6 (also called UVW alignment platforms, which are standard parts) respectively, and adjusts the positions and angles of the two mobile network boxes 3, so that the mobile network box 3 with PI film can better fit the PI film to the FPC, and the empty mobile network box 3 can better absorb the PI film.

[0080] When attaching the PI film, the support mesh 5 (which possesses a certain degree of flexibility) simply needs to be placed on top of the PI film. A conventional mechanism, such as an exhaust fan, then creates a negative pressure within the negative pressure tube 4. The mobile mesh box 3 then simply needs to be raised to separate the PI film from the base film. When attaching the PI film, as the support mesh 5 descends (negative pressure persists within the negative pressure tube 4 from the time the PI film is attached to the FPC), the negative pressure within the negative pressure tube 4 disappears. The clamping motor then rotates the clamping screw 19, which in turn moves the clamping frame 15 along the length of the clamping rail 14. During this movement, the laminating roller 18 (driven downward by the telescopic cylinder 16) applies downward pressure from above, attaching the PI film to the FPC. Simultaneously, negative pressure is generated at the bottom of the platform supporting the FPC (which disappears during the FPC's movement), improving the FPC's positional stability. The platform also generates heat, further enhancing the adhesion between the PI film and the FPC. During the film laminating process, the telescopic cylinder 16 drives the laminating roller 18 so that the laminating roller 18 acts on the support net 5; however, when the film is not laminating, the telescopic cylinder 16 raises the laminating roller 18 so that the support net 5 can be fully laminarized on the PI film.

[0081] Different types of PI films or FPCs have the same width, but their lengths may vary. This requires adjusting the distance between the two adjustment frames 10 within the same camera assembly. This adjustment is accomplished by simply using a motor-driven adjustment screw 13, which moves the two adjustment frames 10 closer or further apart until the proper distance between the two cameras 11 (prior art) is achieved. One camera assembly includes four cameras 11. When capturing the position of the PI film or FPC, four points are captured as markers. These markers are then used to analyze the positions of the PI film, FPC, and the two mobile cages 3.

[0082] When the connecting arm 2 is in the first state, the drag reduction cylinder 26 is located at the bottom of the first vertical slot 21, and the guide portion 38 is lower than the drag reduction cylinder 26. At this time, under the pulling force of the elastic body 40a, the movable column 24 has sufficient position stability.

[0083] Then, after the PI film on one side is adsorbed and the PI film on the other side is attached, the motor drives the lifting screw 43 to rotate, and drives the lifting plate 42, the driving body 41, the driving cylinder 27, the synchronization part 32 and the driving part 31 to rise. During the lifting process, the top of the inclined guide part 38 first hits the bottom side of the drag reduction cylinder 26. Since the two sides of the drag reduction cylinder 26 are limited by the first vertical groove 21, the first vertical surface 28 and the driving part 31, it can only rise vertically within the first channel. At this time, the movable column 24 drives the connecting arm 2 and the two movable cages 3 to rise;

[0084] After rising to a certain height, the drag reduction cylinder 26 is higher than the top of the driving part 31, and at this time the drag reduction cylinder 26 also moves to the arc-shaped groove part at the connection point of the first vertical groove 21 and the horizontal groove 22. At this time, under the guiding action of the arc-shaped groove at the connection point of the first vertical groove 21 and the horizontal groove 22, and under the joint action of the guide part 38 and the second driving inclined surface 33 at the top of the driving part 31, the drag reduction cylinder 26 moves into the horizontal groove 22. At this time, the connecting arm 2 exhibits horizontal swinging until the drag reduction cylinder 26 hits the two elastic limit blocks 40; then the driving cylinder 27 and the driving part 31 continue to rise, so that the drag reduction cylinder 26 passes over the first two elastic limit blocks 40 and moves to the rear two elastic limit blocks 40 (When the drag reduction cylinder 26 passes through the elastic limit block 40, the elastic limit block 40 is elastically deformed; grooves are provided on the top inner wall and the bottom inner wall of the horizontal groove 22, and the elastic limit block 40 is located in the groove. When the drag reduction cylinder 26 hits the elastic limit block 40, the elastic limit block 40 can act as a resistance to the drag reduction cylinder 26. At the same time, when the elastic limit block 40 is subjected to a large force, the elastic limit block 40 can also be driven by the drag reduction cylinder 26 to undergo elastic deformation and enter the corresponding groove). At this time, the drag reduction cylinder 26 is limited and kinetic energy is consumed by the four elastic limit blocks 40, so that the drag reduction cylinder 26 can stop rotating. At this time, the connecting arm 2 is parallel to the PI film and FPC, and can maintain its position stable.

[0085] After the shooting is completed, the PI film movement is completed, the FPC movement is completed, and the VUW platform activity is completed, the driving cylinder 27 is further raised, and continues to drive the drag reduction cylinder 26 to rotate through the second driving inclined surface 33 until it rotates another 90 degrees. At this time, the drag reduction cylinder 26 is located at the top of the second vertical groove 23 and at the bottom of the second vertical surface 29.

[0086] Then the driving cylinder 27 is lowered. At this time, under the action of the gravity of each structure and the pulling force of the elastic body 40a, the connecting arm 2 moves downward until it reaches the bottom of the second vertical groove 23 to apply the PI film and take out a new PI film.

[0087] Afterwards, the driving cylinder 27 rises again, and the drag reduction cylinder 26 is raised to the top of the horizontal groove 22 through the top of the first driving inclined surface 30; the driving cylinder 27 continues to rise, and the first inclined surface drives the drag reduction cylinder 26 to rotate in the horizontal groove 22 (if the previous rotation is clockwise, the rotation here is counterclockwise), and stops shooting and fine-tuning the position after rotating 90 degrees; then the driving cylinder 27 continues to rise, causing the drag reduction cylinder 26 to rotate 90 degrees, so that the drag reduction cylinder 26 returns to the top of the first vertical groove 21, and at the same time the drag reduction cylinder 26 is located at the bottom of the first vertical surface 28, and the drag reduction cylinder 26 is located below the unidirectional body.

[0088] Then the driving cylinder 27 descends until the lower side of the one-way body acts on the top of the drag reduction cylinder 26. The drag reduction cylinder 26 drives the one-way body to swing, and the one-way body and the guide part 38 are both accommodated in the opening of the extension part 34. After the guide part 38 passes over the drag reduction cylinder 26, the one-way body and the guide part 38 rotate outward under the elastic force of the elastic part 39 until the outer side of the one-way body contacts the end part 36, waiting for the next raising of the drag reduction cylinder 26.

[0089] In another embodiment, the lifting and rotating mechanism includes a lifting cylinder vertically fixed on the supporting base plate 1, and a rotating motor or a rotating cylinder is provided on the piston rod of the lifting cylinder, and the output shaft of the rotating motor or the piston rod of the rotating cylinder is connected to the connecting arm 2.

[0090] When taking and sticking the PI film, the lifting cylinder drives the rotating motor or rotating cylinder and the connecting arm 2 to lower, and completes the taking and sticking of the PI film; then the lifting cylinder drives the rotating motor or rotating cylinder and the connecting arm 2 to rise, and then the rotating motor or rotating cylinder drives the connecting arm 2 to rotate 90 degrees for shooting and adjusting the position, and after rotating 90 degrees again, the lifting cylinder raises the position of the connecting arm 2 to take and stick the PI film next time.

[0091] The above description is only a description of the preferred embodiments of the present invention and does not limit the scope of the present invention. Any changes and modifications made by ordinary technicians in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
