Description

Technical Field

[0001] The utility model relates to the technical field of circuit board feeding devices, in particular to a flexible circuit board transmission device. Background Art

[0002] Flexible circuit board is also called flexible circuit board. It is a kind of printed circuit board with high reliability and excellent flexibility made of polyimide or polyester film as the base material. It is referred to as soft board or FPC for short. It has the characteristics of high wiring density, light weight, thin thickness and free bending.

[0003] Most flexible circuit boards are processed through assembly lines. During processing, the flexible circuit boards need to be transported from one end to the other. Transmission means conveying, so that each process can be completed in sequence. At this time, a conveying device is needed. The existing conveying device is mainly a conveyor belt, which is driven by a motor to rotate and drive the material to move forward in a straight line. Because flexible circuit boards are all rolled up, their length after unfolding can be more than tens of meters, and they need to be transported continuously rather than in small independent pieces. Therefore, the existing conveyor belts are not very suitable for the transportation of flexible circuit boards. In addition, the conveyor belt is a whole, with a large volume, which is not convenient to install and replace, and cannot be installed and maintained separately. Utility Model Content

[0030] Reference Figure 1-Figure 7 A flexible circuit board transmission device comprises a body 1, a transmission slot 2 opened on the top of the body 1, a plurality of active components 3 and a plurality of driven components 4 are installed side by side in the transmission slot 2, and the plurality of driven components 4 are evenly distributed. The active component 3 and the driven component 4 both comprise a rotating shaft 300, a plurality of roller components 301 which are sleeved and limited on the rotating shaft 300 in parallel, and two sleeves 302 which are sleeved and fixed at both ends of the rotating shaft 300. The active component 3 and the driven component 4 are installed parallel to each other up and down, and a board-walking space 5 for a flexible circuit board 12 to pass through is formed between the roller components 301 of the active component 3 and the driven component 4; the roller component 301 comprises a roller 301a, and sleeves 301b which are integrally formed at both ends of the roller 301a; an arc-shaped card edge 301c and an arc-shaped card groove 301d are arranged at one end of the sleeve 302 and at both ends of the sleeve 301b, and an arc-shaped card edge 301c and an arc-shaped card groove 301d are arranged between two adjacent roller components 301 and between the sleeve 302 and the adjacent roller components 301. A roller assembly 301 is inserted and limited together by an arc-shaped clamping edge 301c and an arc-shaped clamping groove 301d. A screw hole 302a is radially opened on the outer wall of the sleeve 302. A screw connection 302b is threadedly connected in the screw hole 302a, which can be a screw, a screw or a bolt. The screw connection 302b fixes the sleeve 302 and the rotating shaft 300 together; it also includes a plurality of support seats 6 arranged side by side and mounted on the fuselage 1 on one side of the transmission groove 2. A power shaft 7 is rotatably connected between the plurality of support seats 6. One end of the power shaft 7 is connected to the output shaft of a motor 8. The motor 8 is mounted in the fuselage 1. A plurality of first bevel gears 9 are coaxially fixed on the power shaft 7. A second bevel gear 10 is coaxially mounted at one end of the rotating shaft 300 of each active assembly 3. The first bevel gear 9 is meshed with the second bevel gear 10. When the power shaft 7 rotates, it drives the first bevel gear 9, the second bevel gear 10 and the rotating shaft 300 to rotate synchronously.

[0031] When in use, a plurality of roller assemblies 301 are sleeved on the shaft 300, and the roller assemblies 301 are limited together after being plugged in by the arc-shaped clamping edge 301c and the arc-shaped clamping groove 301d, and then a sleeve 302 is sleeved on each end of the shaft 300, and the sleeve 302 and the roller assembly 301 are also limited together after being plugged in by the arc-shaped clamping edge 301c and the arc-shaped clamping groove 301d, and the two sleeves 302 can prevent the roller assemblies 301 from axially moving or rotating, and then the screw 302b is screwed into the screw hole 302a located on the outer wall of the sleeve 302, and the end of the screw 302b is pressed against the outer wall of the shaft 300, so that the two are tightly connected. Specifically, the number of roller assemblies 301 can be increased or decreased according to the width of the flexible circuit board 12. After installing each active component 3 and each driven component 4 in the above manner, one end of the flexible circuit board 12 is extended into the board space 5, and the rollers 301a on the active component 3 and the driven component 4 press the upper and lower surfaces of the flexible circuit board 12 accordingly. Start the motor 8, the motor 8 drives the power shaft 7 to rotate, and the first bevel gears 9 on the power shaft 7 rotate synchronously, while driving the second bevel gear 10, the rotating shaft 300 and the roller 301a on the active component 3 to rotate synchronously. At this time, the flexible circuit board 12 will continue to move forward in a straight line, and the roller 301a on the driven component 4 will also rotate in the process of the flexible circuit board 12 moving forward. The roller 301a on the driven component 4 can be used to prevent the flexible circuit board 12 from tilting up or shifting. The present application is easy to install, disassemble and replace, and each component can be replaced independently, with relatively low maintenance costs. The flexible circuit board 12 is not easy to tilt or shift during transmission.

[0032] In some embodiments, two vertical plates 11 are symmetrically installed on the fuselage 1 on both sides of the transmission slot 2. The two vertical plates 11 are vertically arranged with respect to each rotating shaft 300. A plurality of groups of shaft holes are opened on each vertical plate 11. Each group of shaft holes includes two shaft holes 110 opened side by side up and down. The upper shaft hole 110 is used for rotationally installing the rotating shaft 300 on the driven component 4, and the lower shaft hole 110 is used for rotationally installing the rotating shaft 300 on the active component 3. Both ends of the rotating shaft 300 are rotationally installed in the shaft holes 110 on the two vertical plates 11. The structure is simple and the installation is relatively convenient.

[0033] In some embodiments, the first bevel gear 9 and the second bevel gear 10 both include a conical gear body 900, and a plurality of bevel teeth 901 are evenly arranged on the outer wall of one end of the gear body 900. The first bevel gear 9 and the second bevel gear 10 achieve synchronous rotation after the bevel teeth 901 are meshed. The structure is simple and stable.

[0034] In some embodiments, the transmission slot 2 is a U-shaped slot, and the arc-shaped clamping edge 301c and the arc-shaped clamping slot 301d are both semicircular, and the two semicircles just form a complete circle. This structure is easy to assemble and can achieve a quick connection between the two.
