Description

Technical Field

[0001] The present invention belongs to the technical field of flexible circuit board processing, and in particular relates to an intelligent material receiving mechanism for flexible circuit boards and a fast pressing all-in-one device. Background Art

[0002] Flexible circuit boards, also known as soft boards or FPC boards, are printed circuits made from a flexible insulating substrate. Compared to rigid resin circuit boards, flexible circuit boards offer advantages such as higher wiring density, lighter weight, thinner thickness, fewer wiring space restrictions, and greater flexibility.

[0003] When laminating flexible circuit boards, a release film + FPC + release film loading method is used. The purpose of the lamination process is to press the upper and lower cover molds of the FPC board into one with the FPC board body under the protective effect of the upper and lower release films (the FPC board itself has a laminated cover film on the upper and lower layers, which is different from the upper and lower film paper). After the lamination process, the FPC board has a certain degree of stickiness, so the upper and lower film paper must be separated from the FPC board and the FPC board is collected. The lamination process of flexible circuit boards is cumbersome, and manual loading and collection are mostly used in this process, and no automated equipment is used to replace human operation. The existing automatic collection process mostly uses a single belt drive structure for collection, that is, the workpiece is placed on the belt and automatically falls into the collection bin via the belt transmission. The problem with this solution is that the products are scattered and disorderly when falling into the hopper, which is easy to bend and damage the products. Especially when two products are collected at the same time, the scattered collection phenomenon is more serious due to the lack of synchronization between the two products.

[0004] Therefore, how to carry out automatic loading and intelligent material collection in the FPC board lamination process has always been a technical problem that needs to be solved urgently in this industry. Summary of the Invention

A Z-axis driving cylinder 709 is respectively arranged on the left and right sides of the head of the T-shaped plate 708. A film suction plate 710 is driven and connected below each of the Z-axis driving cylinders 709, which are a left film suction plate 7101 and a right film suction plate 7102 respectively.

[0072] The left film suction plate 7101 and the right film suction plate 7102 of the upper and lower manipulator feeding mechanisms are driven by their respective Z-axis drive cylinders 709 to independently absorb the workpiece, and then move to the right to the pre-discharge position through the common X-axis drive cylinder 707; when the left and right film suction plates of the upper and lower manipulator feeding mechanisms reach the pre-discharge position, the Y-axis drive motor 704 drives the upper and lower manipulator feeding mechanisms to move to the four-roller meshing mechanism 6 through the screw transmission, and pushes the workpiece into the four-roller meshing mechanism 6, while realizing the pre-bonding of the upper and lower film papers on the workpiece, and then the four-roller meshing mechanism 6 rolls and pre-presses the film papers before sending them to the pressing mechanism 5 for pressing.

[0073] The two groups of the quick-pressing device's paper-reeling and feeding mechanisms 10 are arranged alternately at the front end of the frame 4; wherein, the upper group of the quick-pressing device's paper-reeling and feeding mechanisms 10 include an upper film paper unwinding shaft 1001 and an upper film paper rewinding shaft 1002, and the lower group of the quick-pressing device's paper-reeling and feeding mechanisms include a lower film paper unwinding shaft 1003 and a lower film paper rewinding shaft 1004; the upper film paper unwinding shaft 1001 is arranged at the upper end, and the upper film paper rewinding shaft 1002 and the lower film paper unwinding shaft 1003 are arranged side by side from back to front. It is placed in the middle position, and the lower mold paper winding shaft 1004 is set at the bottom; the upper film paper unwinding shaft and the lower film paper unwinding shaft are both sleeved with film paper 11, and the film paper 11 passes through the corresponding upper and lower four-roller meshing mechanisms 6 to reach the corresponding upper and lower film paper winding shafts for winding. At the same time, the frame 4 is also provided with a multi-axis anti-paper suction mechanism, and the multi-axis anti-paper suction mechanism includes several paper guide rods 1005; the paper guide rods 1005 are used to spread the film paper 11 so as to reduce the paper feed margin of the film paper 11.

[0074] The working process of the quick pressing integrated device of this embodiment is as follows: Figure 9 As shown, specifically:

[0075] First, the upper film paper unwinding shaft 1001 pre-places a sufficient length of film paper 11, and the film paper 11 passes through the upper and lower pairs of rollers of the four-roller meshing mechanism 6, specifically passes through the contact and matching position of the main roller 602 and the auxiliary roller 603, and then reaches the upper film paper rewinding shaft 1002. The upper film paper rewinding shaft 1002 pre-winds a certain length of film paper 11 for use in lamination; similarly, the lower film paper unwinding shaft 1003 pre-places a sufficient length of film paper 11, and the film paper 11 passes through the upper and lower pairs of rollers of the four-roller meshing mechanism 6, specifically passes through the contact and matching position of the main roller 602 and the auxiliary roller 603, and then reaches the lower film paper rewinding shaft 1004. The lower film paper rewinding shaft 1004 pre-winds a certain length of film paper 11 for use in lamination;

[0076] Secondly, the film suction plates 710 of the manipulator feeding mechanisms 7 of the upper and lower sets of quick pressing devices suck the FPC board to be pressed from the hopper 8 and move it to the feeding port of the four-roller meshing mechanism 6 under the drive of the three-axis power assembly. The film suction plates 710 push the FPC board into the meshing position of the upper and lower main rollers 602 of the four-roller meshing mechanism 6 and then release the FPC board. At this time, the upper and lower sides of the FPC board are covered with film paper, forming an overall structure of upper film paper-FPC board-lower film paper. This overall structure is moved to the pressing mechanism under the rotation drive of the upper and lower main rollers of the four-roller meshing mechanism 6;

[0077] Subsequently, the pressure plate driving mechanism under the lower pressure plate 503 is driven upward, so that the lower pressure plate 503 drives the middle pressure plate 502 to move upward together, so that the lower pressure plate 503, the middle pressure plate 502 and the upper pressure plate 501 are pressed together, completing the FPC board pressing of the two sets of fast pressing devices; then the pressure plate driving mechanism moves downward, so that the three pressure plates are separated; during the entire process of the pressure plate pressing and separating, the four-roller meshing mechanism 6 is moved by the cooperation of the strip boss 601 and the bearing step 504;

[0078] Finally, the four-roller meshing mechanism 6 and the paper-rewinding and feeding mechanism 10 both operate in reverse, and the upper and lower film papers are pulled away to the right, driving the pressed workpiece to move right. The pressed workpiece exits the pressing mechanism 5 and the four-roller meshing mechanism 6 in turn. During this process, the upper and lower film papers and the FPC board are peeled off from top to bottom; after the FPC board is completely peeled off, it automatically falls onto the transmission belt of the intelligent material-receiving mechanism 9 for automatic material rewinding; at the same time, the upper and lower film paper rewinding shafts rewind the used film paper and rewind a certain length of new film paper to prepare for the next workpiece processing.

[0079] In addition, it should be noted that the film suction plate of the manipulator loading and unloading mechanism of the embodiment of the present invention is divided into a left film suction plate and a right film suction plate. The left and right film suction plates can each absorb a small-sized FPC board, or can simultaneously absorb a large-sized FPC board, and there is no restriction on this. At the same time, the intelligent material collection mechanism of the embodiment of the present invention is a double-belt material collection mechanism, which can complete the collection of two small-sized FPC boards on the left and right, or can simultaneously complete the collection of a large-sized FPC board, with flexible material collection and unloading, and there is no restriction on this. In addition, the double film suction plate structure and double-belt material collection mechanism of the embodiment of the present invention can also be replaced with a single film suction plate structure and a single-belt material collection mechanism according to the actual processing requirements of the product. This replacement is a simple adjustment of the corresponding structure in the embodiment of the invention and will not be repeated here.

[0080] The above description is only an embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the scope of the present invention shall be included in the scope of protection of the present invention.
