Description

Technical Field

[0001] This utility model relates to the field of dry film pre-applying machine technology, and more particularly to a feeding and tapping mechanism for an FPC dry film pre-applying machine. Background Technology

[0002] In the processing of FPC (Flexible Printed Circuit), dry film needs to be applied to both sides of the FPC. Existing FPC dry film pre-applied machines use a feeding mechanism to transport the FPC material to one side of a robotic arm. The robotic arm then picks up the FPC from the feeding mechanism and places it at the film-applied station for application. Because the feeding mechanism does not transport the FPC to a uniform position, there is a certain deviation when the robotic arm picks up the FPC, resulting in deviations when the FPC is placed at the film-applied station, affecting the accuracy of the film application. Utility Model Content

[0003] The problem to be solved by this utility model is to provide a feeding and patting mechanism for an FPC dry film pre-applying machine, which can perform a patting operation on the material during feeding to improve processing accuracy.

[0004] To solve the above technical problems, a feeding and tapping mechanism for an FPC dry film pre-lamination machine provided by this utility model is provided, comprising a conveying mechanism, a front baffle, a transverse tapping mechanism, and a material blocking mechanism; the conveying mechanism includes a support, several parallel rollers, and a first servo motor; the support includes two oppositely arranged side plates and several connecting beams connecting the two side plates; the rollers are rotatably connected between the two side plates; the first servo motor is disposed on one of the side plates and is used to drive the rollers to rotate; the front baffle is fixedly connected between one end of the two side plates; the transverse tapping mechanism includes a left tapping mechanism, The right-side striking mechanism and opening / closing drive mechanism, as well as the left-side and right-side striking mechanisms, all include a transverse sliding plate and a striking plate. Several uprights are connected between the transverse sliding plate and the striking plate, and the uprights are movably positioned in the gap between two adjacent rollers. The opening / closing drive mechanism is used to drive the two transverse sliding plates closer or further apart. The bottom of the striking plate is provided with an arc-shaped clearance groove that matches the roller, and the roller is movably positioned on the arc-shaped clearance groove. The material blocking mechanism includes a lifting cylinder set on one of the connecting beams and a material blocking plate driven and connected to the lifting cylinder. The material blocking plate is movably positioned in the gap between two adjacent rollers.

[0005] Preferably, the opening and closing drive mechanism includes a second servo motor, a first synchronous belt, a driving synchronous pulley, and a driven synchronous pulley. A first support plate is fixedly connected to one side plate, the second servo motor is mounted on the first support plate, and the driving synchronous pulley is mounted on the output shaft of the second servo motor. A second support plate is fixedly connected to the other side plate, and the driven synchronous pulley is rotatably connected to the second support plate. The first synchronous belt connects the driving synchronous pulley and the driven synchronous pulley. A connecting plate is provided on the transverse slide plate, and a synchronous tooth groove is provided on the connecting plate. The first synchronous belt meshes with the synchronous tooth groove. Several transverse guide rods are fixedly connected between the two side plates, and the transverse slide plate and the transverse guide rods are connected by a first guide sleeve.

[0006] Preferably, the bottom of the baffle plate is connected to several longitudinal guide rods, and a second guide sleeve corresponding to the longitudinal guide rods is fixedly connected to the connecting beam, with the longitudinal guide rods connected to the second guide sleeves.

[0007] Preferably, a number of bearing seats are arranged side by side on the outer side surface of one of the side plates, a worm gear is connected to the bearing seat, a worm wheel that meshes with the worm gear is connected to one end of the roller, and the first servo motor is connected to the worm gear through a second synchronous belt drive.

[0008] The beneficial effects of this utility model are as follows: This utility model provides a feeding and clapping mechanism for an FPC dry film pre-lamination machine. Initially, the baffle plate is lower than the highest point of the roller. The roller rotates under the drive of the first servo motor, conveying the FPC material onto the roller. The FPC will be conveyed to the front baffle side under the drive of the roller. After the rear end face of the FPC passes the vertical plane where the baffle plate is located, the baffle plate is driven to rise above the highest point of the roller by the lifting cylinder. The baffle plate can intercept the conveying of the next FPC. When the front end face of the FPC contacts the inner wall of the front baffle, the FPC stops being conveyed forward. The horizontal sliding plates of the left and right clapping mechanisms are driven to approach each other by the opening and closing drive mechanism. When the two clapping plates approach each other, the FPC can be clapped to the middle position, which makes it convenient for the robot to grasp the FPC in a uniform position, ensuring that the FPC is placed in the designated position of the lamination station and improving the processing accuracy.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure.

[0017] Based on the embodiments described in this disclosure, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this disclosure.

[0018] refer to Figures 1-6 .

[0019] This utility model provides a feeding and tapping mechanism for an FPC dry film pre-applying machine, comprising a conveying mechanism 1, a front baffle 2, a transverse tapping mechanism 3, and a material blocking mechanism 4. The conveying mechanism 1 includes a support 10, several parallel rollers 11, and a first servo motor 12. The support 10 includes two oppositely arranged side plates 100 and several connecting beams 101 connecting the two side plates 100. The rollers 11 are rotatably connected between the two side plates 100. The first servo motor 12 is disposed on one of the side plates 100 and is used to drive the rollers 11 to rotate. The front baffle 2 is fixedly connected between one end of the two side plates 100. The transverse tapping mechanism 3 includes a left tapping mechanism 30, a right tapping mechanism 31, and an opening and closing drive mechanism 3. 2. Both the left-side striking mechanism 30 and the right-side striking mechanism 31 include a transverse sliding plate 300 and a striking plate 301. Several uprights 302 are connected between the transverse sliding plate 300 and the striking plate 301. The uprights 302 are movably disposed in the gap between two adjacent rollers 11. The opening and closing drive mechanism 32 is used to drive the two transverse sliding plates 300 to move closer or further away. The bottom of the striking plate 301 is provided with an arc-shaped clearance groove 301a that matches the roller 11. The roller 11 is movably disposed on the arc-shaped clearance groove 301a. The material blocking mechanism 4 includes a lifting cylinder 40 disposed on one of the connecting beams 101 and a material blocking plate 41 that is driven and connected to the lifting cylinder 40. The material blocking plate 41 is movably disposed in the gap between two adjacent rollers 11.

[0020] Its working principle is as follows: Initially, the baffle plate 41 is lower than the highest point of the roller 11. The roller 11 rotates under the drive of the first servo motor 12, conveying the FPC material onto the roller 11. The FPC will be conveyed to the front baffle 2 side under the drive of the roller 11. After the rear end face of the FPC passes the vertical plane where the baffle plate 41 is located, the lifting cylinder 40 drives the baffle plate 41 to rise to a position higher than the highest point of the roller 11. The baffle plate 41 can intercept the conveying of the next FPC. When the front end face of the FPC contacts the inner wall of the front baffle 2, the FPC stops conveying forward. The opening and closing drive mechanism 32 drives the horizontal slide plates 300 of the left and right centering mechanisms 30 and 31 to approach each other. When the two side plates 301 approach each other, the FPC can be slapped to the middle position, which makes it convenient for the robot to grasp the FPC in a uniform position, ensuring that the FPC is placed in the designated position of the film laminating station and improving the processing accuracy.

[0021] Based on the above embodiments, the opening and closing drive mechanism 32 includes a second servo motor 320, a first synchronous belt 321, an active synchronous pulley 322, and a driven synchronous pulley 323. A first support plate 324 is fixedly connected to one side plate 100, the second servo motor 320 is disposed on the first support plate 324, and the active synchronous pulley 322 is disposed on the output shaft of the second servo motor 320. A second support plate 325 is fixedly connected to the other side plate 100, and the driven synchronous pulley 323 is rotatably connected to the second support plate 325. The first synchronous belt 321 is connected between the active synchronous pulley 322 and the driven synchronous pulley 323. A connecting plate 300a is disposed on the transverse slide plate 300, and a synchronous tooth groove is disposed on the connecting plate 300a. The first synchronous belt 321 is meshed with the synchronous tooth groove. A plurality of transverse guide rods 326 are fixedly connected between the two side plates 100. The transverse slide plate 300 and the transverse guide rods 326 are connected by a first guide sleeve 327. Specifically, the connecting plate 300a on the left side of the striking mechanism 30 and the connecting plate 300a on the right side of the striking mechanism 31 should be staggered so that the two connecting plates 300a are staggered and connected to both sides of the first synchronous belt 321. When the second servo motor 320 is working, the first synchronous belt 321 will rotate forward or backward, thereby driving the striking plate 301 on the left side of the striking mechanism 30 and the striking plate 301 on the right side of the striking mechanism 31 to move closer or further away.

[0022] Based on the above embodiments, a plurality of longitudinal guide rods 410 are connected to the bottom of the baffle plate 41, and a second guide sleeve 101a corresponding to the longitudinal guide rods 410 is fixedly connected to the connecting beam 101. The longitudinal guide rods 410 are connected to the second guide sleeve 101a. When the baffle plate 41 is driven to move up and down by the lifting cylinder 40, the longitudinal guide rods 410 will move along the second guide sleeve 101a, playing a guiding role.

[0023] Based on the above embodiment, a plurality of bearing seats 13 are arranged side by side on the outer surface of one side plate 100. A worm gear 14 is connected to the bearing seat 13. One end of the roller 11 is connected to a worm wheel 110 that meshes with the worm gear 14. The first servo motor 12 is connected to the worm gear 14 via a second synchronous belt 15. When the first servo motor 12 is working, it will drive each roller 11 to rotate synchronously, which has good transmission stability and transmission accuracy, and is easy to maintain.

Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
