Description

Technical Field

[0001] The invention relates to the field of FPC processing technology, in particular to a device and method for locally and selectively roughening the surface of an FPC. Background Art

[0002] Flexible circuit boards, also known as soft circuit boards or flexible circuit boards, are highly favored by people for their excellent properties such as light weight, thin thickness, and free bending and folding. However, the quality inspection of FPC in China still mainly relies on manual visual inspection, which is costly and inefficient. With the rapid development of the electronics industry, circuit board design is becoming more and more high-precision and high-density. Traditional manual inspection methods can no longer meet production needs, and automated inspection of FPC defects has become an inevitable trend in industrial development. When processing FPC, manufacturers often print some characters and logos on the surface of FPC according to customer assembly or traceability requirements.

[0003] Since the surface of FPC is relatively smooth, when characters or logos are directly printed, the formed characters and logos are easy to fall off from the board after a period of use (before the end of life). In order to solve this problem, most existing FPC manufacturers use plasma equipment to indiscriminately roughen the surface of FPC, and then print characters and logos on the surface after roughening. However, roughening with plasma equipment needs to be carried out in a high temperature and vacuum environment, which not only consumes more energy and has a high processing cost, but also takes a long time for plasma equipment processing, which makes the overall processing efficiency low. Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the invention

[0004] In view of this, the present invention aims to address the deficiencies in the prior art, and its main purpose is to provide a local and selective roughening device and roughening method for the FPC surface, which can effectively solve the problems of high energy consumption, high processing cost and low processing efficiency in the existing FPC roughening process.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A device for locally and selectively roughening the surface of an FPC comprises a frame, a controller, a movable plate assembly, a mounting frame, a laser generator and a laser output assembly; the controller is arranged on the frame; the movable plate assembly can be movably arranged on the frame back and forth; the mounting frame is arranged on the frame and is located above the movable plate assembly; the laser generator is arranged on the mounting frame and connected to the controller; the laser output assembly can be movably arranged on the mounting frame back and forth horizontally and connected to the controller, and the laser output assembly is connected to the output end of the laser generator, and the laser output assembly corresponds to the position of the movable plate assembly.

[0007] As a preferred solution, the movable plate assemblies are arranged in two symmetrical lateral arrangements, and the corresponding laser generators and laser output assemblies are also provided in two arrangements. The two laser generators and the two laser output assemblies are respectively provided on mounting frames and are located above the corresponding movable plate assemblies.

[0008] As a preferred solution, a cover is provided on the frame, and the mounting frame, the laser generator and the laser output assembly are all covered by the cover, and the movable plate assembly moves out of the cover as it moves forward and backward.

[0009] As a preferred solution, the frame is provided with a first track extending forward and backward, and the movable plate assembly includes a loading plate, a first slide seat and a first driving mechanism; the first slide seat is arranged on the loading plate and cooperates with the first slide rail; the first driving mechanism is arranged on the loading plate and drives the loading plate to move back and forth along the first track.

[0010] As a preferred solution, a telescopic first dust cover is provided on the first track.

[0011] As a preferred solution, the laser output assembly is connected to the laser generator via a laser transmission pipeline, and a reflection unit for reflecting laser light is provided in the laser transmission pipeline.

[0012] As a preferred solution, the mounting frame is provided with a second track extending laterally; the laser output assembly includes a movable seat, a second slide seat, a second driving mechanism and a laser output head; the second slide seat is arranged on the movable seat and cooperates with the second track; the second driving mechanism is arranged on the movable seat and drives the movable seat to move back and forth along the second track, and the second driving mechanism is connected to the controller; the laser output head is arranged on the movable seat and moves back and forth with the movable seat, and the laser output head is connected to the controller.

[0013] As a preferred solution, a telescopic second dust cover is provided on the second track.

[0014] As a preferred solution, the laser output assembly further includes a detection head, which is disposed on the movable seat and located beside the laser output head.

[0015] A roughening method for an FPC surface roughening device comprises the following steps:

[0016] (1) Turn on the roughening equipment and controller, and import the data of the product to be roughened into the controller;

[0017] (2) The movable seats in the two laser output assemblies are respectively moved toward the left and right sides under the drive of their second driving mechanisms, so that the laser output heads are located outside the corresponding movable plate assemblies;

[0018] (3) placing the product to be roughened on two carrier plates, and then driving the corresponding carrier plates toward the laser output assembly through the first driving mechanism;

[0019] (4) When the carrier plate moves the product to be roughened to the bottom of the laser output assembly, the laser generator starts working and roughens the corresponding part of the product to be roughened through the laser output head;

[0020] (5) After the roughening is completed, the first driving mechanism and the second driving mechanism respectively drive the carrier plate and the movable seat to reset, and the roughened product can be removed.

[0021] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

The laser roughening method does not need to indiscriminately roughen the entire plate surface under high temperature and vacuum environment, effectively reducing the energy consumption of the equipment and reducing the processing cost. Because the roughening is local and selective, its processing efficiency is higher than that of indiscriminately roughened plasma.

[0041] Please refer to Figures 1 to 5 As shown, it shows the specific structure of a preferred embodiment of the present invention, which includes a frame 10, a controller 20, a movable plate assembly 30, a mounting frame 40, a laser generator 50 and a laser output assembly 60.

[0042] The controller 20 is disposed on the frame 10; in this embodiment, a cover 11 is disposed on the frame 10. The frame 10 is provided with a first track 12 extending forward and backward, and a telescopic first dust cover 13 is sleeved on the first track 12. The first dust cover 13 is used to prevent external dust from entering the first track 12, thereby ensuring the stability of the movable plate assembly 30 during the movement process on the first track 12;

[0043] The movable plate assembly 30 can be movably arranged on the frame 10 back and forth; in the present embodiment, there are two movable plate assemblies 30 arranged symmetrically in the transverse direction. The movable plate assembly 30 moves out of the hood 11 as it moves back and forth. When loading and after processing, the hood 11 can be moved outward through the movable plate assembly 30, thereby facilitating the loading and unloading process of the product. The movable plate assembly 30 includes a loading plate 31, a first slide seat 32 and a first driving mechanism 33; the first slide seat 32 is arranged on the loading plate 31 and cooperates with the first slide rail 12; the first driving mechanism 33 is arranged on the loading plate 32 and drives the loading plate to move back and forth along the first rail 32

[0044] The mounting frame 40 is disposed on the frame 10 and is located above the movable plate assembly 30; in the present embodiment, a second track 41 extending laterally is disposed on the mounting frame 40; a telescopic second dust cover 42 is provided on the second track 41, and the second dust cover 42 is used to prevent external dust from entering the second track 41, thereby ensuring the stability of the movement process of the laser output assembly 60 when it moves along the second track 41.

[0045] The laser generator 50 is disposed on the mounting frame 40 and connected to the controller 20 .

[0046] The laser output assembly 60 can be movably arranged on the mounting frame 40 and connected to the controller 20, and the laser output assembly 60 is connected to the output end of the laser generator 50. The laser output assembly 60 corresponds to the position of the movable plate assembly 30, so that after the laser generated by the laser generator 50 is transmitted to the laser output assembly 60, the laser output assembly 60 emits the laser generated by the laser generator 50, thereby performing a roughening process on the product on the movable plate assembly 30. The laser generator 50 and the laser output assembly 60 are also two settings, and the two laser generators 50 and the two laser output assemblies 60 are respectively arranged on the mounting frame and located above the corresponding movable plate assembly, so that the roughening of two products can be performed at the same time, further increasing the overall processing efficiency. The mounting frame 40, the laser generator 50 and the laser output assembly 60 are all covered by the machine cover 11, and the machine cover 11 plays a certain protective role on the mounting frame 40, the laser generator 50 and the laser output assembly 60, and can also prevent external interference during the roughening process, ensuring the stability of the roughening process.

[0047] The laser output assembly 60 is connected to the laser generator 50 via a laser transmission pipeline 70. A reflection unit 71 for reflecting laser light is disposed in the laser transmission pipeline 70, so that the direction of laser transmission can be changed by disposing the laser transmission pipeline 70 and the reflection unit 71. This eliminates the need to position the laser output assembly 60 in correspondence with the output end of the laser generator 50 during installation. The laser output assembly 60 and the laser generator 50 can be arranged front to back without being arranged horizontally, so that the required installation space is more flexible. The laser output assembly 60 includes a movable seat 61, a second slide 62, a second drive mechanism 63 and a laser output head 64; the second slide 62 is arranged on the movable seat 61 and cooperates with the second track 41; the second drive mechanism 63 is arranged on the movable seat 61 and drives the movable seat 61 to move back and forth along the second track 41, and the second drive mechanism 63 is connected to the controller 20; the laser output head 64 is arranged on the movable seat 61 and moves back and forth with the movable seat 61, the laser output head 64 is connected to the controller 20, and the laser output head 64 is connected to the output end of the laser generator 50. The laser output assembly 60 also includes a detection head 65, which is arranged on the movable seat 61 and located beside the laser output head 64. The detection head 65 can not only be used to detect the position of the product on the movable plate assembly 30, but also detect the effect after roughening, so that the operator can timely remove the unqualified roughening products.

[0048] The roughening process of this embodiment is described in detail as follows:

[0049] (1) Turn on the roughening equipment and controller, and import the data of the product to be roughened into the controller;

[0050] (2) The movable seats in the two laser output assemblies are respectively moved toward the left and right sides under the drive of their second driving mechanisms, so that the laser output heads are located outside the corresponding movable plate assemblies;

[0051] (3) placing the product to be roughened on two carrier plates, and then driving the corresponding carrier plates toward the laser output assembly through the first driving mechanism;

[0052] (4) When the carrier plate moves the product to be roughened to the bottom of the laser output assembly, the laser generator starts working and roughens the corresponding part of the product to be roughened through the laser output head;

[0053] (5) After the roughening is completed, the first driving mechanism and the second driving mechanism respectively drive the carrier plate and the movable seat to reset, and the roughened product can be removed.

[0054] Similarly, you can choose the left and right laser output components to perform local and selective roughening processing on two products at the same time, or you can choose one of the laser output components to complete the roughening processing of a single-side product.

[0055] The design focus of the present invention is that by providing a laser generator and a laser output component, and cooperating with the laser output component to be movably arranged on a mounting frame laterally and back and forth and connected to a controller, and the laser output component corresponds to the position of the movable plate component, so that by using laser roughening to replace the existing plasma roughening, the laser roughening method does not need to indiscriminately roughen the entire plate surface under high temperature and vacuum environment, effectively reducing the energy consumption of the equipment and reducing the processing cost. Because the roughening is local and selective, its processing efficiency is higher than that of indiscriminately roughened plasma.

[0056] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
