Description

Technical Field

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

[0002] In the processing of FPC (Flexible Printed Circuit), dry film needs to be laminated onto both sides of the FPC. Existing FPC dry film pre-lamination machines typically have a loading mechanism consisting of a conveyor belt and a robotic arm. The robotic arm picks up and places the FPC onto the conveyor belt for transport. Since the position of the conveyor belt is fixed, the robotic arm needs to travel horizontally to pick up and place the FPC from the hopper onto the conveyor belt. This type of loading mechanism is relatively large, and the robotic arm has a long travel distance, resulting in low loading efficiency. Utility Model Content

[0003] The problem to be solved by this utility model is to provide an FPC feeding mechanism that reduces the size of the equipment and improves the feeding efficiency.

[0004] To solve the above-mentioned technical problems, an FPC feeding mechanism provided by this utility model is provided, comprising a support, a material picking and placing mechanism, a conveyor belt mechanism, and a forward and backward driving mechanism; the material picking and placing mechanism comprises a stand mounted on the support, a Z-axis linear drive mechanism mounted on the stand, and a suction mechanism driven and connected to the Z-axis linear drive mechanism; the conveyor belt mechanism comprises two side plates arranged in parallel and a conveyor belt driven between the two side plates; the forward and backward driving mechanism comprises two horizontal guide rods arranged in parallel on the support and a forward and backward driving cylinder, the two side plates are connected to the horizontal guide rods through a first guide sleeve, the forward and backward driving cylinder is fixedly connected to one end of one of the side plates, and the output shaft of the forward and backward driving cylinder is fixedly connected to one side of the support.

[0005] Preferably, the suction mechanism includes a Z-axis slide block slidably connected to the stand along the Z-axis direction, a support beam fixedly connected to the Z-axis slide block, horizontal mounting plates respectively disposed at both ends of the support beam, and a plurality of suction cup assemblies disposed at the bottom of the horizontal mounting plates. The support beam and the horizontal mounting plates are connected by a plurality of buffer assemblies. The Z-axis linear drive mechanism includes a servo motor disposed at the top of the stand, and the servo motor is connected to the Z-axis slide block by a lead screw.

[0006] Preferably, the buffer assembly includes a second guide sleeve that passes through the support beam, a connecting rod that is movably disposed on the second guide sleeve, a limiting ring that is fixedly connected to the top end of the connecting rod, and a buffer spring. The bottom end of the connecting rod is fixedly connected to the horizontal mounting plate, and the buffer spring is sleeved on the connecting rod and abuts against the support beam and the horizontal mounting plate.

[0007] Preferably, the suction cup assembly includes a suction cup slide block slidably connected to the bottom of the horizontal mounting plate, a plurality of suction cups disposed at the bottom of the suction cup slide block, a screw hole being provided through the side wall of the suction cup slide block, a positioning bolt being connected to the screw hole, and one end of the positioning bolt abutting against the side wall of the horizontal mounting plate.

[0008] The beneficial effects of this utility model are as follows: This utility model provides an FPC feeding mechanism. To facilitate the material handling mechanism's picking action, the hopper should be located below the suction mechanism, and the conveyor belt mechanism can move back and forth under the drive of the forward and backward drive cylinder. When the picking mechanism picks up material from the hopper, the conveyor belt mechanism should be located below and behind the picking mechanism to avoid obstructing the suction mechanism's picking action from the hopper. The suction mechanism is driven to move up and down by the Z-axis linear drive mechanism to pick up one FPC from the hopper. After the picking mechanism completes the picking action, the conveyor belt mechanism is driven to move below the suction mechanism by the forward and backward drive cylinder. Then, the suction mechanism is driven to descend by the Z-axis linear drive mechanism to place the FPC on the conveyor belt. The conveyor belt then transports the FPC to the next workstation. This can shorten the robot's travel distance, effectively reduce the size of the feeding mechanism, and improve feeding efficiency. Attached Figure Description

[0013] 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.

[0014] 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.

[0015] refer to Figures 1-3 .

[0016] This utility model provides an FPC feeding mechanism, comprising a support 1, a material handling mechanism 2, a conveyor belt mechanism 3, and a forward / backward drive mechanism 4. The material handling mechanism 2 includes a stand 20 mounted on the support 1, a Z-axis linear drive mechanism 21 mounted on the stand 20, and a suction mechanism 22 driven and connected to the Z-axis linear drive mechanism 21. The conveyor belt mechanism 3 includes two side plates 30 arranged in parallel and a conveyor belt 31 driven between the two side plates 30. The forward / backward drive mechanism 4 includes two horizontal guide rods 40 arranged in parallel on the support 1 and a forward / backward drive cylinder 41. The two side plates 30 are connected to the horizontal guide rods 40 through a first guide sleeve 42. The forward / backward drive cylinder 41 is fixedly connected to one end of one of the side plates 30, and the output shaft of the forward / backward drive cylinder 41 is fixedly connected to one side of the support 1.

[0017] Its working principle is as follows: To facilitate the material handling mechanism 2's material handling action, the hopper should be located below the suction mechanism 22, and the conveyor belt mechanism 3 can move back and forth under the drive of the forward and backward drive cylinder 4. When the material handling mechanism 2 picks up material from the hopper, the conveyor belt mechanism 3 should be located below and behind the material handling mechanism 2 to avoid obstructing the suction mechanism 22's material handling action from the hopper. The suction mechanism 22 is driven up and down by the Z-axis linear drive mechanism 21 to pick up one FPC from the hopper. After the material handling mechanism 2 completes the material handling action, the conveyor belt mechanism 3 is driven by the forward and backward drive cylinder 4 to move below the suction mechanism 22. Then, the suction mechanism 22 is driven down by the Z-axis linear drive mechanism 21 to place the FPC on the conveyor belt 31. The conveyor belt 31 then transports the FPC to the next workstation. This can shorten the robot's travel distance, effectively reduce the size of the loading mechanism, and improve loading efficiency.

[0018] Based on the above embodiments, the material suction mechanism 22 includes a Z-axis slide 220 slidably connected to the stand 20 along the Z-axis direction, a support beam 221 fixedly connected to the Z-axis slide 220, horizontal mounting plates 222 respectively disposed at both ends of the support beam 221, and a plurality of suction cup assemblies 223 disposed at the bottom of the horizontal mounting plates 222. The support beam 221 and the horizontal mounting plates 222 are connected by a plurality of buffer assemblies 224. The Z-axis linear drive mechanism 21 includes a servo motor 210 disposed at the top of the stand 20. The servo motor 210 is connected to the Z-axis slide 220 by a lead screw. When the servo motor 210 is working, it can drive the Z-axis slide 220 to move up and down, thereby driving the material suction mechanism 22 to move up and down to perform material picking and placing actions. When the suction cup assembly 223 picks up material from the hopper and places the material on the conveyor belt 31, the buffer assembly 224 plays a buffering role to prevent damage to the FPC.

[0019] Based on the above embodiments, the buffer assembly 224 includes a second guide sleeve 224a that passes through the support beam 221, a connecting rod 224b that is movably disposed on the second guide sleeve 224a, a limiting ring 224c that is fixedly connected to the top end of the connecting rod 224b, and a buffer spring 224d. The bottom end of the connecting rod 224b is fixedly connected to the horizontal mounting plate 222, and the buffer spring 224d is sleeved on the connecting rod 224b and abuts against the support beam 221 and the horizontal mounting plate 222. When the suction cup assembly 223 sucks material from the hopper and places the material on the conveyor belt 31, the connecting rod 224b will move along the second guide sleeve 224a, and the buffer spring 224d will be compressed, playing a buffering role and preventing damage to the FPC during the material handling process.

[0020] Based on the above embodiments, the suction cup assembly 223 includes a suction cup slide 223a slidably connected to the bottom of the horizontal mounting plate 222, and a plurality of suction cups 223b disposed at the bottom of the suction cup slide 223a. A screw hole is provided through the side wall of the suction cup slide 223a, and a positioning bolt 223c is connected to the screw hole. One end of the positioning bolt 223c abuts against the side wall of the horizontal mounting plate 222, which can adjust the position of the suction cup slide 223a on the horizontal mounting plate 222 and realize the positioning between the suction cup slide 223a and the horizontal mounting plate 222, thereby adjusting the position of each suction cup assembly 223 on the horizontal mounting plate 222 to adsorb FPCs of different sizes.

[0021] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. 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.
