Description

Technical Field

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

[0002] Flexible printed circuits, also known as soft or flexible printed circuits (FPCs), are highly sought after for their lightweight, thin, and flexible bends. However, domestic FPC quality inspection still relies primarily on manual visual inspection, which is costly and inefficient. With the rapid development of the electronics industry, circuit board designs are increasingly moving towards high precision and high density. Traditional manual inspection methods are no longer sufficient for production needs, and automated FPC defect detection is becoming an inevitable trend in the industry. During FPC processing, manufacturers often print text and logos on the FPC surface to meet customer assembly or traceability requirements.

[0003] Because the FPC surface is relatively smooth, when characters or logos are directly printed on it, the formed characters and logos are prone to falling off the board after a period of use (before reaching the end of its life). To solve this problem, most existing FPC manufacturers use plasma equipment to indiscriminately roughen the FPC surface before printing characters and logos on the surface. However, using plasma equipment for roughening requires high temperature and vacuum environment, which not only increases energy consumption and processing costs, but also takes a long time for plasma equipment processing, thus reducing overall processing efficiency. Therefore, it is necessary to develop a new technical solution to solve the above problems. Utility Model Content

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

[0005] In order 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 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 laterally 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 set in two. The two laser generators and the two laser output assemblies are respectively set on the mounting frame and located above the corresponding movable plate assemblies.

[0008] As a preferred solution, a cover is provided on the frame, and the mounting frame, laser generator and 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 and a first driving mechanism; the first slide is provided on the loading plate and cooperates with the first slide rail; the first driving mechanism is provided 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, a second drive mechanism and a laser output head; the second slide is provided on the movable seat and cooperates with the second track; the second drive mechanism is provided on the movable seat and drives the movable seat to move back and forth along the second track, and the second drive mechanism is connected to the controller; the laser output head is provided 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 arranged on the movable seat and located beside the laser output head.

[0015] 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:

[0016] By providing a laser generator and a laser output component, and cooperating with the laser output component to be movable back and forth laterally on a mounting frame and connected to a controller, and the laser output component and the movable plate component correspond in position, the existing plasma roughening method is replaced by laser roughening. The laser roughening method does not require indiscriminate roughening of the entire plate surface under high temperature and vacuum environment, effectively reducing the energy consumption of the equipment and lowering the processing cost. Precisely because the roughening is local and selective, its processing efficiency is higher than that of indiscriminately roughened plasma.

[0035] 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.

[0036] The controller 20 is mounted on a frame 10. In this embodiment, the frame 10 is provided with a cover 11. The frame 10 is provided with a first track 12 extending forward and backward. The first track 12 is covered with a telescopic first dust cover 13. The first dust cover 13 is used to prevent external dust from entering the first track 12, thereby ensuring the stability of the movable panel assembly 30 during movement on the first track 12.

[0037] The movable plate assembly 30 can be movably arranged on the frame 10 back and forth; in this 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 32 and a first driving mechanism 33; the first slide 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.

[0038] The mounting frame 40 is set on the frame 10 and is located above the movable plate assembly 30; in this embodiment, a second track 41 extending laterally is provided 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.

[0039] The laser generator 50 is mounted on the mounting bracket 40 and connected to the controller 20 .

[0040] The laser output assembly 60 is movably mounted on the mounting frame 40 and connected to the controller 20. 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 light generated by the laser generator 50 is transmitted to the laser output assembly 60, the laser output assembly 60 emits the laser light generated by the laser generator 50, thereby roughening the product on the movable plate assembly 30. The laser generator 50 and the laser output assembly 60 are also two devices, with the two laser generators 50 and the two laser output assemblies 60 respectively mounted on the mounting frame and located above the corresponding movable plate assembly, allowing roughening of two products simultaneously, further increasing overall processing efficiency. The mounting frame 40, the laser generator 50, and the laser output assembly 60 are all covered by a cover 11. The cover 11 provides protection for the mounting frame 40, the laser generator 50, and the laser output assembly 60, and also prevents external interference during the roughening process, ensuring a stable roughening process.

[0041] 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 provided in the laser transmission pipeline 70, so that the direction of laser transmission can be changed by setting the laser transmission pipeline 70 and the reflection unit 71. Therefore, during installation, there is no need to position the laser output assembly 60 corresponding to the output end of the laser generator 50. 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 also 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 mounted on the movable seat 61 and engages with the second track 41. The second drive mechanism 63 is mounted on the movable seat 61 and drives the movable seat 61 to move back and forth along the second track 41. The second drive mechanism 63 is connected to the controller 20. The laser output head 64 is mounted 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 is in communication with the output end of the laser generator 50. The laser output assembly 60 also includes a detection head 65, which is mounted on the movable seat 61 and located next to the laser output head 64. The detection head 65 can be used to detect the position of the product on the movable plate assembly 30 and the effect of the roughening process, allowing the operator to promptly remove unqualified products.

[0042] The coarsening process of this embodiment is described in detail as follows:

[0043] (1) Turn on the roughening equipment and controller, and import the data of the product to be roughened into the controller;

[0044] (2) The movable seats in the two laser output assemblies are respectively driven by their second driving mechanisms to move toward the left and right sides, so that the laser output heads are located outside the corresponding movable plate assemblies;

[0045] (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;

[0046] (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;

[0047] (5) After the roughening is completed, the first driving mechanism and the second driving mechanism respectively drive the material carrier and the movable seat to reset, and the roughened product can be removed.

[0048] Similarly, you can choose the left and right laser output components to perform local, 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-sided product.

[0049] The design focus of the utility model is that: by providing a laser generator and a laser output component, and cooperating with the laser output component to be movable back and forth laterally on a mounting frame and connected to a controller, and the laser output component and the movable plate component correspond in position, so that by adopting laser roughening instead of 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 lowering the processing cost. Precisely because the roughening is local and selective, its processing efficiency is higher than that of indiscriminately roughened plasma.

[0050] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor 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.
