Description

Technical Field

[0002] Flexible printed circuit (FPC), also known as soft circuit board, flexible circuit board, is highly favored for its excellent characteristics such as light weight, thin thickness, and free bending and folding. With the rapid development of the electronics industry, circuit board design is becoming more and more high-precision and high-density. Traditional manual detection methods can no longer meet production needs, and FPC defect automation detection has become an inevitable trend in industrial development. Flexible circuit is a technology developed by the United States in the 1970s for the development of space rocket technology. It is a printed circuit with high reliability and excellent flexibility made of polyester film or polyimide as the substrate. By embedding the circuit design on the bendable thin plastic sheet, a large number of precision components are stacked in a narrow and limited space, thus forming a bendable flexible circuit. This kind of circuit can be bent and folded at will, is light in weight, small in size, has good heat dissipation, and is easy to install, breaking through the traditional interconnection technology. In the structure of the flexible circuit, the materials are insulating film, conductor and adhesive.

[0077] The present invention provides a material transfer mechanism for an efficient laminating machine. First, there is a PI film to be taken on one side of the device (there is a base film under the PI film, and the base film is used to support the PI film for movement), and there is an FPC to be laminated on the other side, and the PI film and the FPC are parallel and at the same height.

[0078] When the PI film is attached to the FPC, the two mobile net boxes 3 are in the lowest state, wherein the negative pressure tube 4 of the mobile net 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 net box 3 on the other side disappears, and the PI film on the mobile net 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 net 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, and in this process 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 then descends. 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. Such reciprocating motion can make the film pasting efficient; wherein the connecting arm 2 rotates counterclockwise and clockwise in turn, rather than rotating in only one direction.

[0079] When the connecting arm 2 is in the second state, the two shooting components located at the top respectively shoot the PI film and the FPC, wherein the purpose of shooting the PI film is to obtain accurate data of the position of the PI film, and the purpose of shooting the FPC is to obtain accurate data of the position of the FPC; at the same time, the two shooting components located at the bottom respectively obtain accurate data of the empty mobile mesh box 3 and the mobile mesh 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 mesh boxes 3, so that the mobile mesh box 3 with PI film can better fit the PI film to the FPC, and the empty mobile mesh box 3 can better absorb the PI film.

[0080] When the PI film is adsorbed, only the support net 5 (with a certain flexibility) needs to be attached to the top of the PI film, and then the conventional mechanism such as the exhaust fan forms a negative pressure in the negative pressure tube 4, and then the mobile net box 3 only needs to be raised to peel the PI film from the base film. When the PI film is attached, during the downward process of the support net 5 (the negative pressure in the negative pressure tube 4 continues to exist during the process of adsorbing the PI film to the bonding process), after the PI film is attached to the FPC, the negative pressure in the negative pressure tube 4 disappears, and then the clamping motor drives the clamping screw 19 to rotate, and drives the clamping frame 15 to move along the length direction of the clamping rail 14. During this activity, the laminating roller 18 (driven by the telescopic cylinder 16 to move downward) applies pressure from top to bottom, so that the PI film is attached to the FPC; at the same time, the bottom of the platform supporting the FPC also generates negative pressure (the negative pressure disappears during the movement of the FPC), which improves the position stability of the FPC; and the platform supporting the FPC also generates heat, so that the PI film and the FPC are better attached. During the film laminating process, the telescopic cylinder 16 drives the laminating roller 18 so that the laminating roller 18 acts on the supporting net 5; however, when the film is not laminating, the telescopic cylinder 16 raises the laminating roller 18 so that the supporting net 5 can be fully laminating on the PI film.

[0081] The widths of different types of PI films or FPCs are all equal, but the lengths are different. In this case, it is necessary to adjust the distance between the two adjustment frames 10 in the same shooting assembly. During the adjustment, the motor only needs to drive the adjustment screw 13, and the adjustment screw 13 can drive the two adjustment frames 10 to move closer or farther from each other until the distance between the two groups of cameras 11 (existing technology) reaches an appropriate value. One of the shooting assemblies includes four cameras 11. When shooting the position of the PI film or FPC, four points are shot as mark points, and the positions of the PI film, FPC and two mobile cages 3 are analyzed based on the four mark points.

[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 groove 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 lower 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 be lifted vertically in the first channel. At this time, the movable column 24 drives the connecting arm 2 and the two mobile 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 guiding 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 a horizontal swing 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 grooves. 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 in a parallel state with the PI film and FPC, and its position can be kept 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 ramp 33, and 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 is lowered to 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, so that the drag reduction cylinder 26 rotates 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, and the drag reduction cylinder 26 drives the one-way body to swing, and makes the one-way body and the guide part 38 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 member 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, a rotating motor or a rotating cylinder is arranged 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 the taking and sticking of the PI film is completed. 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. After rotating 90 degrees, the lifting cylinder raises the position of the connecting arm 2 for the next taking and sticking of the PI film.

[0091] The above description is only a description of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention. Any changes or modifications made by a person skilled in the art in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
