Description

Technical Field

[0001] This utility model relates to the field of FPC processing technology, specifically to a cover plate loading device for FPC drilling. Background Technology

[0002] FPC (Flexible Printed Circuit) is a type of flexible electronic interconnect component made from a flexible substrate (such as polyimide PI, polyester PET, etc.) through processes such as etching. It is lightweight, flexible, and resistant to high and low temperatures, and is widely used in consumer electronics, automotive electronics, medical devices, and other fields.

[0003] Drilling is a critical step in the manufacturing process of FPC (Flexible Printed Circuit Board), primarily used to achieve interlayer circuit continuity (such as through holes and blind vias) or to provide mounting channels for component pins. A drilling cover plate (or simply cover plate) is used to cover the drilled area of ​​the FPC during drilling to reduce vacuum leakage.

[0004] In the existing technology, the cover plate is transported by a conveyor belt, and then a robot arm is used to remove the cover plate from the conveyor belt for loading. The accuracy of loading the cover plate onto the FPC is low, which cannot reduce vacuum leakage. In addition, the loading efficiency is low and the cost is high. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a cover plate feeding device for FPC drilling, which can realize precise and rapid feeding of cover plates and improve production efficiency.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

The hopper module includes a hopper and a feeding assembly. The feeding assembly is located at the bottom of the hopper, and the hopper contains a cover plate. The feeding assembly is used to remove the cover plate from the bottom of the hopper. The robotic arm module includes a loading robotic arm and a traversing module. The traversing module is mounted on the crossbeam of the gantry frame, and the loading robotic arm is mounted on the drive end of the traversing module. The loading robotic arm is used to pick up the cover plate removed by the feeding assembly, and the traversing module drives the loading robotic arm to move along the crossbeam of the gantry frame.

[0008] As a further improvement to the above technical solution, the hopper includes a feed inlet at the top and a discharge outlet at the bottom. The feeding assembly includes a feeding plate and a feeding drive. The feeding plate is provided with a groove for accommodating a cover plate. The feeding plate is slidably connected to the bottom of the hopper. The feeding drive is used to drive the feeding plate to reciprocate between the picking position and the feeding position. When the feeding plate is in the picking position, the groove is located directly below the discharge outlet.

[0009] As a further improvement to the above technical solution, the feeding plate is provided with a negative pressure chamber inside, and the bottom of the groove is provided with a plurality of negative pressure holes, which are connected to the negative pressure chamber, and the negative pressure chamber is connected to an external vacuum device.

[0016] The beneficial effects of this invention are as follows: Several cover plates are loaded into a hopper, and these cover plates can be sequentially removed from the hopper. A robotic arm then removes the cover plates and places them on an FPC board. The structure is compact, the transport distance is short, and the movements are smooth, effectively improving the feeding efficiency of the cover plates.

[0026] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / connections involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. For example, fixed connections / fixed installations can use screw connections, bolt connections, pin connections, key connections, adhesive connections, mortise and tenon connections, welding, riveting, etc., as needed. For detachable connections, screw connections, bolt connections, threaded connections, snap-fit ​​connections, mortise and tenon connections, Velcro connections, etc., can be used as needed. The various technical features in this utility model can be combined interactively without contradicting each other.

[0027] Reference Figures 1-7 This utility model provides an FPC drilling cover plate loading device 400, including a gantry frame 410 and a hopper module 420 and a robotic arm module 430 mounted on the gantry frame 410. The hopper module 420 includes a hopper 421 and a feeding assembly, which is located at the bottom of the hopper 421. A support plate 424 is provided on one of the columns of the gantry frame 410, and a support block 425 is provided on the support plate 424. The hopper 421 is fixedly mounted on the support plate 424 by two of the support blocks 425. The hopper 421 has a rectangular frame structure and has a storage space inside for loading cover plates 440. The top of the storage space is a feed inlet, and the bottom of the storage space is a discharge outlet. The feeding assembly can move the cover plates 440 out sequentially from the bottom of the hopper 421 so that the robotic arm module 430 can pick up the cover plates 440.

[0028] The gantry 410 is used to span above the first linear motor 100, which drives the fixture 200, on which the FPC board 300 is mounted, to move along the Y-axis. The robotic arm module 430 includes a loading robotic arm and a transverse module. The transverse module is mounted on the crossbeam of the gantry 410, and the loading robotic arm is mounted on the drive end of the transverse module. The transverse module is used to drive the loading robotic arm to move along the X-axis (the length direction of the crossbeam of the gantry), thereby removing the cover plate 440 removed from the hopper 421.

[0029] In this embodiment, refer to Figures 3-6The feeding assembly includes a feeding plate 422 and a feeding drive component. The feeding plate 422 is provided with a groove 428 for accommodating a cover plate 440. The shape of the groove 428 is the same as that of the cover plate 440, and the size of the groove 428 is slightly larger than that of the cover plate 440. This facilitates the receiving of the cover plate 440 moving downwards from the bottom outlet of the hopper 421 due to gravity, and also enables the positioning of the cover plate 440, preventing it from being too skewed. In this embodiment, the groove 428 accommodates only one cover plate 440, that is, the depth of the groove 428 is approximately the same as the thickness of one cover plate 440, ensuring that the feeding plate 422 is not obstructed when moving the cover plate 440 out of the hopper 421.

[0030] The bottom of the hopper 421 is provided with a chute, and the feeding plate 422 is slidably connected to the chute. The length direction of the chute is set along the X-axis, so that the feeding plate 422 can only move along the X-axis. When the feeding plate 422 moves, it can remove the cover plate 440 in the groove 428 out of the hopper 421, thereby facilitating the loading robot to pick it up. It can be understood that when the feeding plate 422 moves, that is, after the groove 428 leaves the bottom of the hopper 421, the upper surface of the feeding plate 422 blocks the outlet, thereby preventing the remaining cover plates 440 from falling down. When the groove 428 returns to the bottom of the hopper 421, a new cover plate 440 falls into the groove 428.

[0031] Furthermore, the feed plate 422 is provided with a negative pressure chamber 426 inside, and the bottom of the groove 428 is provided with a plurality of negative pressure holes 427. The plurality of negative pressure holes 427 are connected to the negative pressure chamber 426. The negative pressure chamber 426 is connected to an external vacuum device through a negative pressure pipe joint 429. This can generate negative pressure at the negative pressure holes 427, which will adsorb the cover plate 440 in the groove 428 and prevent the cover plate 440 from shaking when it moves with the feed plate 422.

[0032] In this embodiment, the feeding drive includes a feeding cylinder 423. The telescopic end of the feeding cylinder 423 is connected to the feeding plate 422, and the fixed end of the feeding cylinder 423 is mounted on the support plate 424. The telescopic movement of the feeding cylinder 423 can realize the reciprocating motion of the feeding plate 422, thereby realizing the action of conveying the cover plate 440 from the material picking position to the material loading position and the reset action.

[0033] In other embodiments, the feeding drive can be a linear module such as a hydraulic cylinder, an electric cylinder, or a linear motor.

[0034] In this embodiment, refer to Figure 3 and Figure 7The loading robot includes a negative pressure suction nozzle 435 and a lifting drive component. The lifting drive component is installed on the drive end of the transverse module, and the negative pressure suction nozzle 435 is installed on the drive end of the lifting drive component. The lifting drive component is used to drive the negative pressure suction nozzle 435 to move along the Z-axis. When the transverse module drives the loading robot to the loading position, the lifting drive component drives the negative pressure suction nozzle 435 to move downward to contact the cover plate 440 and thus pick up the cover plate 440. Then it moves upward to reset. Next, the transverse module drives the loading robot to the unloading position, and the lifting drive component drives the negative pressure suction nozzle 435 to move downward to place the cover plate 440 on the FPC board 300. After the cover plate 440 is placed, it moves upward to reset.

[0035] Furthermore, the driving end of the lifting drive component is provided with a buffer block 434, and the buffer block 434 is provided with a mounting hole. The negative pressure suction nozzle 435 is slidably connected in the mounting hole, and a buffer spring 436 is connected between the negative pressure suction nozzle 435 and the buffer block 434. In this way, when the lifting drive component drives the negative pressure suction nozzle 435 to move downward to pick up / place the cover plate 440, a buffering force can be provided to avoid damage to the negative pressure suction nozzle 435 due to hard contact.

[0036] In this embodiment, the transverse module includes a second linear motor 431, the lifting drive component is a lifting cylinder 433, the fixed end of the lifting cylinder 433 is connected to the moving part 432 of the second linear motor 431, and the buffer block 434 is installed on the telescopic end of the lifting cylinder 433.

[0037] In other embodiments, the lifting drive component may be a linear module such as a hydraulic cylinder, an electric cylinder, or a linear motor.

All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
