Technical Field

[0001] The utility model relates to the field of assembly lines, in particular to a fixture return transmission line. Background Art

[0002] With the rapid development of the national economy, the continuous advancement of science and technology, and the rapid development of modern communication technology, the appearance and volume of products are also constantly changing, and flexible circuit boards are becoming more and more widely used. Flexible circuit boards need to undergo PSA lamination and target punching during the production process. PSA lamination is to use a laminating machine to coat a layer of PSA film on the flexible circuit board, which is used to prevent dust, oxidation and static electricity, and mainly plays a protective role; then, the laminated flexible circuit board needs to be placed in a jig and transferred to the target punching machine with the jig for target punching. After that, the flexible circuit board after target punching is transferred to other workstations without the need to use a jig.

[0003] In order to save transfer time, a conveyor line for conveying jigs is usually set up between the laminating machine and the target shooting machine. Conventional conveyor lines are generally linear, which have the following problems: (1) The placement space is long and is not suitable for use in smaller workshops; (2) The jigs cannot be returned, and workers need to walk a long distance to retrieve the jigs, which results in great physical exertion of the workers. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model provides a jig return conveying line, including a laminating discharge conveyor line extending in the longitudinal direction, and also including a transverse conveying mechanism, a docking station and a reflux conveyor line. The reflux conveyor line is arranged in parallel with the laminating discharge conveyor line, and the conveying directions of the reflux conveyor line and the laminating discharge conveyor line are opposite. The docking station is arranged between the discharge end of the laminating discharge conveyor line and the feed end of the transverse conveying mechanism, and one end of the reflux conveyor line is connected to the discharge end of the transverse conveying mechanism; the transverse conveying mechanism includes a transverse frame, a bearing mechanism and a cap removing mechanism. The transverse frame extends in the transverse direction, the bearing mechanism is movably arranged on the transverse frame, the bearing mechanism can move back and forth between the docking station and the reflux conveyor line, the cap removing mechanism is arranged on the transverse frame so as to move up and down, and the cap removing mechanism is arranged above the bearing mechanism.

[0006] It can be seen from the above scheme that by setting up a docking station, the jig with the flexible circuit board on the bonding and discharging conveyor line can be transferred to the transverse conveying mechanism; by setting up a reflux conveyor line, it is used to automatically return the jig with the flexible circuit board removed, which is convenient for recycling. Compared with the prior art, it is beneficial to save workers' labor and improve work efficiency; by setting the reflux conveyor line in parallel with the bonding and discharging conveyor line, compared with the prior art, it is beneficial to shorten the length of the placement space and is more suitable for use in smaller workshops; by setting up a bearing mechanism, it is used to realize the lateral movement of the jig in the transverse frame; by setting up a cover removal mechanism, it is convenient to take up the upper cover of the jig before the target shooting machine takes the material, so that the flexible circuit board is exposed on the bottom plate of the jig. After the target shooting machine takes the material, the upper cover is put back on the bottom plate, which is convenient for the complete recovery of the jig.

[0007] A further solution is that guide rails and transverse linear modules are arranged in parallel on the transverse frame, and the bearing mechanism is arranged on the guide rails and the transverse linear module. The guide rails extend in the transverse direction, and the transverse linear module can drive the bearing mechanism to move back and forth along the extension direction of the guide rails.

[0008] A further solution is that the carrying mechanism includes a base, a stopper and two carrying and conveying components, the two carrying and conveying components are arranged on the base opposite to each other in the transverse direction, a longitudinal placement groove for accommodating the jig is formed between the two carrying and conveying components, the stopper is arranged on one end of the longitudinal placement groove away from the docking platform, and the carrying and conveying components can convey the jig to the stopper.

[0009] It can be seen from the above scheme that by setting up a load-bearing conveying assembly, when a part of the jig enters the longitudinal placement groove, the load-bearing conveying assembly is started to convey the jig forward so that the entire jig is completely conveyed into the longitudinal placement groove.

[0010] A further solution is that a buffer pad is provided on one side of the stopper.

[0011] A further solution is that the distance between the two load-bearing conveying components is adjustable.

[0012] It can be seen from the above solution that by setting the distance between the two load-bearing and conveying components to be adjustable, it is beneficial to be compatible with fixtures of different widths.

[0013] A further solution is that the cap removing mechanism is suspended on the transverse moving frame, and the cap removing mechanism includes a lifting drive device, a diverter plate, a mounting plate and a plurality of vacuum suction cups. The diverter plate is connected to the driving end of the lifting drive device, and an air inlet connector and a plurality of air outlet connectors are provided on the diverter plate.

[0015] A further solution is that the position of the vacuum suction cup on the mounting plate is adjustable.

[0016] It can be seen from the above scheme that by setting the position of the vacuum suction cup on the mounting plate to be adjustable, it is helpful to reasonably adjust the position of the vacuum suction cup according to the size of the upper cover of the fixture and the characteristics of the opening, thereby ensuring that the vacuum suction cup can be adsorbed on the upper cover.

[0017] A further solution is that a plurality of magnetic suction parts are arranged on the mounting plate, and the magnetic suction parts are arranged one-to-one corresponding to the vacuum suction cups. The magnetic suction parts adsorb the corresponding vacuum suction cups onto the mounting plate, and the connecting ends of the vacuum suction cups are made of magnetic metal materials, or the connecting ends of the vacuum suction cups are provided with magnets that are magnetically attracted to the magnetic suction parts.

[0018] It can be seen from the above scheme that by providing a magnetic suction piece to adsorb the vacuum suction cup on the mounting plate, the position of the vacuum suction cup can be adjusted quickly and conveniently.

[0019] A further solution is that the reflux conveying line includes a reflux rack, which extends longitudinally. The reflux rack is provided with a plurality of temporary storage positions arranged along its extension direction. Two reflux conveying components are provided in each temporary storage position. The two reflux conveying components are arranged on the reflux rack opposite to each other in the transverse direction. The reflux conveying components can drive the fixture to move longitudinally.
