Description

Technical Field

[0001] The utility model relates to the technical field of flexible printed circuit board production, in particular to a drum feeding device for the black hole process of flexible printed circuit boards. Background Technique

[0002] At present, flexible printed circuit boards are printed circuits made of flexible insulating substrates. Flexible circuits provide excellent electrical performance, can meet the design requirements of smaller and higher-density installations, and also help to reduce assembly processes and enhance reliability. Due to the large demand for flexible printed circuit boards, it is necessary to optimize the production of flexible printed circuit boards.

[0003] For example, in the Chinese utility model patent with the publication number CN215163137U, a high-efficiency drum feeding device for the black hole process of flexible printed circuit boards is disclosed. In the above prior art, although the liquid medicine can quickly fill both the front and back sides of the flexible printed circuit board, making the film deposition uniform during the black hole process, due to the softness of the flexible printed circuit board itself, the circuit board is generally manually placed inside the drum. Manual feeding and discharging will result in insufficient automation, slow down the production and processing speed of the flexible printed circuit board, and affect production efficiency. Therefore, it is necessary to design a drum feeding device for the black hole process of flexible printed circuit boards that can automatically feed and discharge. Content of the Utility Model

[0004] To solve the technical problem that when a flexible printed circuit board is processed by the black hole process, the staff needs to manually place the circuit board inside the drum, which affects the production and processing speed, the utility model provides a drum feeding device for the black hole process of flexible printed circuit boards.

[0005] The utility model is realized by the following technical solutions: a drum feeding device for the black hole process of flexible printed circuit boards, including a processing box, a drum is arranged on one side of the processing box, a plurality of hanging grooves are opened on the inner wall of the drum, a circuit board assembly is arranged on one side of the drum, a feeding assembly for feeding the circuit board assembly into the hanging grooves is arranged on one side of the circuit board assembly, a blanking assembly for taking out the circuit board assembly from the hanging grooves is arranged on one side of the feeding assembly, and the circuit board assembly includes a feeding box arranged on one side of the drum, a plurality of fixing frames arranged inside the feeding box, and flexible printed circuit boards arranged on each fixing frame.

[0006] Through the above technical solutions, when the servo motor is started, the feeding assembly will drive the circuit board assembly to perform automatic feeding operations, and at the same time, the blanking assembly will also be started to perform automatic blanking operations.

[0007] As a further improvement of the above solution, the fixing frame is adapted to the feeding box, and pushing ports are opened on both sides of the feeding box, and both pushing ports are adapted to the fixing frame.

[0008] Through the above technical solution, after the fixing bracket is pushed, it will enter the inside of the hanging groove from the pushing port with the flexible circuit board.

[0009] As a further improvement of the above solution, the feeding component includes a pushing plate arranged on one side of the feeding box, a servo motor arranged on one side of the pushing plate, and a threaded rod fixedly installed on the output end of the servo motor. One end of the threaded rod threadedly penetrates through the pushing plate and is rotatably installed with a limiting block fixedly installed at the bottom of the feeding box.

[0010] Through the above technical solution, when the servo motor is started, the threaded rod will rotate, so that the pushing plate passes through the pushing port to push the fixing bracket.

[0011] As a further improvement of the above solution, the pushing plate is arranged in an "L" shape, and one side of the pushing plate extends into the adjacent pushing port.

[0012] Through the above technical solution, the pushing plate will be limited by the pushing port when moving, avoiding deviation during movement.

[0013] As a further improvement of the above solution, the discharging component includes a connecting plate fixedly installed on one side of the pushing plate and a discharging rod fixedly installed on one side of the connecting plate.

[0014] Through the above technical solution, after the discharging rod is pushed, it will push the fixing bracket inside the hanging groove, thus completing the discharging operation.

[0015] As a further improvement of the above solution, support plates are fixedly installed at the bottom of the feeding box and the bottom of the servo motor.

[0016] Through the above technical solution, the feeding box and the servo motor are supported and will not hang in the air.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] By setting a circuit board component, a feeding component and a discharging component, the flexible circuit board is installed on the fixing bracket. Cooperating with the feeding component, the flexible circuit board can automatically enter the inside of the drum. Cooperating with the discharging component, the processed flexible circuit board can be discharged while loading. Such a setting can not only perform automatic loading and unloading operations for the black hole process processing of the flexible circuit board, but also reduce the number of staff required to operate the device and lower the labor cost.

[0024] Next, in combination with the accompanying drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.

[0025] Please refer to Figures 1 - 3 , A roller feeding device for black hole process machining of flexible circuit boards in this embodiment includes a processing box 1. A roller 2 is provided on one side of the processing box 1. A plurality of hanging grooves are formed on the inner wall of the roller 2. A circuit board assembly is provided on one side of the roller 2. A feeding component for feeding the circuit board assembly into the hanging grooves is provided on one side of the circuit board assembly. A blanking component for taking out the circuit board assembly from the hanging grooves is provided on one side of the feeding component. The circuit board assembly includes a loading box 301 provided on one side of the roller 2, a plurality of fixed frames 302 provided inside the loading box 301, and a flexible circuit board 303 provided on each fixed frame 302. The fixed frame 302 is adapted to the loading box 301. Pushing ports are formed on both sides of the loading box 301, and both pushing ports are adapted to the fixed frame 302. When the servo motor 402 is started, the feeding component will drive the circuit board assembly to perform an automatic feeding operation, and at the same time, the blanking component will also be started to perform an automatic blanking operation. After the fixed frame 302 is pushed, it will enter the hanging groove with the flexible circuit board 303 from the pushing port.

[0026] Refer to Figure 2 and Figure 3 , The feeding component includes a pushing plate 401 provided on one side of the loading box 301, a servo motor 402 provided on one side of the pushing plate 401, and a threaded rod 403 fixedly installed on the output end of the servo motor 402. One end of the threaded rod 403 threadedly penetrates the pushing plate 401 and is rotatably installed with a limit block 6 fixedly installed at the bottom of the loading box 301. The pushing plate 401 is arranged in an "L" shape, and one side of the pushing plate 401 extends into the adjacent pushing port. When the servo motor 402 is started, the threaded rod 403 will rotate, so that the pushing plate 401 passes through the pushing port to push the fixed frame 302.

[0027] Combined with Figure 1 and Figure 3 , the blanking component includes a connecting plate 501 fixedly installed on one side of the pushing plate 401 and a blanking rod 502 fixedly installed on one side of the connecting plate 501. After the blanking rod 502 is pushed, it will push the fixing frame 302 inside the hanging groove, thus completing the blanking operation.

[0028] Combined with Figure 1 and Figure 2 , support plates 7 are fixedly installed at the bottoms of both the feeding box 301 and the servo motor 402, so that the feeding box 301 and the servo motor 402 are supported and will not hang in the air.

[0029] The implementation principle of a drum feeding device for flexible printed circuit board black hole process machining in the embodiment of the present application is as follows: There is a liquid for black hole process machining inside the processing box 1. The existing drum 2 for black hole process machining has its own drive system. According to the settings of the drive system, set the rotation speed and rotation interval of the servo motor 402. Install multiple flexible printed circuit boards 303 on the adapted fixing frames 302, put the fixing frames 302 into the feeding box 301, and start the servo motor 402. When the hanging groove coincides with the pushing port of the feeding box 301, the drive system will stop the rotation of the drum 2. At the same time, the servo motor 402 will start, causing the threaded rod 403 to rotate, thereby driving the pushing plate 401 to move. When the pushing plate 401 moves through the pushing port, it will push the fixing frame 302, thus pushing the fixing frame 302 into the adjacent hanging groove. The connecting plate 501 on one side of the pushing plate 401 will also push the blanking rod 502 to move, pushing out the fixing frame 302 inside the previous hanging groove to complete blanking, which is convenient for preparing for feeding. When the servo motor 402 makes the threaded rod 403 rotate in the reverse direction, the pushing plate 401 will return to its original position, which is convenient for pushing the next fixing frame 302. Such a setting can not only perform automatic feeding and automatic blanking operations for the black hole process machining of the flexible printed circuit board 303, but also reduce the number of staff required to operate the device, reducing labor costs.

[0030] The above-mentioned implementation manners are only the preferred implementation manners of the present utility model, and cannot be used to limit the scope of protection of the present utility model. Any non-substantial changes and substitutions made by those skilled in the art based on the present utility model fall within the scope of protection required by the present utility model.
