Description

Technical Field

[0001] This utility model belongs to the field of automated FPC shaping technology, specifically relating to an FPC shaping mechanism. Background Technology

[0002] Flexible printed circuit boards (FPCs) are highly reliable and extremely flexible printed circuit boards made with polyimide or polyester film as the substrate. They are characterized by high wiring density, light weight, and thinness. In the assembly of mobile phones, tablets, and other devices, the motherboard and sub-board require ribbon cables for connection. After the BTB (Battery Tolerancing Board) is attached, the FPC needs to be bent and attached to the bottom of the battery compartment, and then bonded to the adhesive backing. The bottom surface must be flat and not bulging.

[0003] In current production, FPC shaping is mostly done manually, requiring careful and meticulous operation. Otherwise, the wiring will not be straightened properly and the speed will be slow. Alternatively, the equipment may shape the FPC before assembling it, which is not conducive to automated assembly. Therefore, we propose an FPC shaping mechanism. Utility Model Content

[0004] The purpose of this invention is to provide an FPC shaping mechanism to solve the problem mentioned in the background art that existing FPCs are mostly shaped manually, resulting in low efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an FPC shaping mechanism, comprising a fixed plate and a BTB body, a large shaping Z-cylinder on one side of the fixed plate, a connecting plate at the bottom of the large shaping Z-cylinder, a small shaping Z-cylinder at the bottom of the connecting plate, side-push cylinders on both sides of the connecting plate, a BTB pressure head and an FPC side push head on one side of the side-push cylinder, an FPC body above the BTB body, and an FPC pressure plate at the bottom of the small shaping Z-cylinder.

[0006] Preferably, a shaping large Z-cylinder is fixedly installed on one side surface of the fixing plate, and a connecting plate is fixedly installed at the bottom output end of the shaping large Z-cylinder.

[0007] Preferably, a shaping small Z-cylinder is fixedly installed in the middle of the bottom surface of the connecting plate, and a side-push cylinder is fixedly installed on both sides of the bottom end of the connecting plate.

[0008] Preferably, a BTB pressure head is fixedly connected to one output end of the side thrust cylinder, and an FPC side thrust head is fixedly connected to one side of the BTB pressure head.

[0009] Preferably, the upper surface of the BTB body is provided with an FPC body, and the bottom output end of the shaping small Z cylinder is fixedly installed with an FPC pressure plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] The device automatically reshapes the FPC after the BTB is attached and adheres it tightly to the bottom adhesive of the battery compartment, ensuring that the FPC is flat and does not bulge, thus improving the device's performance. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: an FPC shaping mechanism, including a fixed plate 1 and a BTB body 8. A shaping large Z cylinder 2 is provided on one side of the fixed plate 1. A connecting plate 3 is provided at the bottom end of the shaping large Z cylinder 2. A shaping small Z cylinder 4 is provided at the bottom of the connecting plate 3. Side push cylinders 5 are provided on both sides of the connecting plate 3. A BTB pressure head 6 and an FPC side push head 7 are provided on one side of the side push cylinder 5. An FPC body 9 is provided above the BTB body 8. An FPC pressure plate 10 is provided at the bottom of the shaping small Z cylinder 4.

[0019] Specifically, a large Z-shaped cylinder 2 is fixedly installed on one side surface of the fixed plate 1, a connecting plate 3 is fixedly installed at the bottom output end of the large Z-shaped cylinder 2, a small Z-shaped cylinder 4 is fixedly installed in the middle of the bottom side surface of the connecting plate 3, side push cylinders 5 are fixedly installed on both sides of the bottom end of the connecting plate 3, a BTB pressure head 6 is fixedly connected to one side output end of the side push cylinder 5, an FPC side push head 7 is fixedly connected to one side of the BTB pressure head 6, an FPC body 9 is provided on the upper surface of the BTB body 8, and an FPC pressure plate 10 is fixedly installed at the bottom output end of the small Z-shaped cylinder 4.

[0020] In this embodiment, before the device is used for shaping, the two ends of the FPC body 9 are first fastened to the surface grooves of the BTB body 8, and the FPC body 9 is arched upwards. Then, the shaping large Z cylinder 2 is activated to press down. The shaping large Z cylinder 2 drives the BTB pressure heads 6 on both sides through the connecting plate 3 to press the surface of the BTB body 8 tightly, so as to prevent the BTB body 8 from being pulled off during the shaping process of the FPC body 9. The two ends of the ribbon cable are pressed to the bottom of the battery compartment. Then, the side push cylinder 5 is activated. Through the extension of the output end of the side push cylinder 5, the FPC side push head 7 is driven to press the ribbon cable to the side wall of the battery compartment. At this time, the ribbon cable is flattened. Finally, the descent of the shaping small Z cylinder 4 can drive the FPC pressure plate 10 to press down, thereby sticking the ribbon cable to the back adhesive at the bottom of the battery, thus achieving the effect of shaping the FPC body 9.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
