Description

Technical Field

[0001] The present invention relates to the field of FPC processing technology, and in particular to an FPC surface local and selective roughening device and roughening method. 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. Summary of the Invention

[0004] In view of this, the present invention addresses the deficiencies in the prior art, and its main purpose is to provide a device and method for local 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] To achieve the above object, 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, there are two movable plate components arranged symmetrically horizontally, and correspondingly, there are also two laser generators and two laser output components. The two laser generators and the two laser output components are respectively arranged on the mounting frame and above the corresponding movable plate components.

[0008] As a preferred solution, a machine cover is arranged on the frame. The mounting frame, the laser generator and the laser output components are all covered by the machine cover, and the movable plate components move out of the machine cover as they move back and forth.

[0009] As a preferred solution, a first track extending forward and backward is arranged on the frame. The movable plate component includes a loading plate, a first sliding seat and a first driving mechanism. The first sliding seat is arranged on the loading plate and cooperates with the first sliding 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 sleeved on the first track.

[0011] As a preferred solution, the laser output component is connected to the laser generator through a laser transmission pipeline, and a reflection unit for reflecting the laser is arranged in the laser transmission pipeline.

[0012] As a preferred solution, a second track extending horizontally is arranged on the mounting frame. The laser output component includes a movable seat, a second sliding seat, a second driving mechanism and a laser output head. The second sliding 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. 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. The laser output head is connected to the controller.

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

[0014] As a preferred solution, the laser output component further includes a detection head, and the detection head is arranged on the movable seat and beside the laser output head.

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

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

[0017] (2). The movable seats in the two laser output components are respectively driven by their second driving mechanisms to move towards the left and right sides, so that the laser output heads are located outside the corresponding movable plate components;

[0018] (3) Place the product to be roughened on two loading plates, and then drive the corresponding loading plate to move towards the laser output component through the first driving mechanism;

[0019] (4) When the loading plate moves the product to be roughened directly below the laser output component, the laser generator works, and the laser output head roughens the corresponding place of the product to be roughened;

[0020] (5) After roughening is completed, drive the loading plate and the movable seat to return to their original positions respectively by the first driving mechanism and the second driving mechanism, and then remove the roughened product.

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

The laser roughening method does not require non-discriminatory roughening of the entire board surface in a high-temperature and vacuum environment, effectively reducing the energy consumption of the equipment and lowering the processing cost. Because it is local and selectively roughened, its processing efficiency is higher than that of non-discriminatory roughening plasma.

[0041] Please refer to Figures 1 to 5 as shown, which shows the specific structure of the preferred embodiment of the present invention, including 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 arranged on the frame 10; in this embodiment, a machine cover 11 is arranged on the frame 10. A first track 12 extending forward and backward is arranged on the frame 10, 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, ensuring the stability of the movable plate assembly 30 during its movement on the first track 12;

[0043] The movable plate assembly 30 is arranged on the frame 10 so as to be movable back and forth; in this embodiment, two movable plate assemblies 30 are arranged symmetrically in the horizontal direction. The movable plate assembly 30 moves out of the machine cover 11 as it moves back and forth. When loading and after processing are completed, the movable plate assembly 30 can move out of the machine cover 11 outward, facilitating the loading and unloading process of products. The movable plate assembly 30 includes a loading plate 31, a first sliding seat 32 and a first driving mechanism 33; the first sliding 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 track 32.

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

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

[0046] The laser output assembly 60 is arranged on the mounting bracket 40 so as to be movable back and forth horizontally 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 coarsening the products on the movable plate assembly 30. The laser generator 50 and the laser output assembly 60 are also provided in two sets. The two laser generators 50 and the two laser output assemblies are respectively arranged on the mounting bracket and above the corresponding movable plate assemblies, so that the coarsening of two products can be carried out simultaneously, further increasing the overall processing efficiency. The mounting bracket 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 for the mounting bracket 40, the laser generator 50 and the laser output assembly 60, and at the same time can also prevent interference from the outside during the coarsening process, ensuring the stability of the coarsening process.

[0047] The laser output component 60 is connected to the laser generator 50 through a laser transmission pipeline 70. A reflection unit 71 for reflecting the laser is arranged in the laser transmission pipeline 70, so that the direction of laser transmission can be changed through the arrangement of the laser transmission pipeline 70 and the reflection unit 71. When installing, it is not necessary to align the output ends of the laser output component 60 and the laser generator 50 in terms of position. The laser output component 60 and the laser generator 50 can be arranged front and back, without the need for horizontal arrangement, making the required installation space more flexible. The laser output component 60 includes a movable seat 61, a second sliding seat 62, a second driving mechanism 63 and a laser output head 64; the second sliding seat 62 is arranged on the movable seat 61 and cooperates with the second track 41; the second driving 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. The second driving 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 communicated with the output end of the laser generator 50. The laser output component 60 further includes a detection head 65. The detection head 65 is arranged on the movable seat 61 and 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 component 30, but also detect the effect after roughening, which is convenient for the operator to timely remove the products with unqualified roughening.

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

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

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

[0051] (3). Place the products to be roughened on the two loading plates, and then drive the corresponding loading plates to move towards the laser output components through the first driving mechanism;

[0052] (4). When the loading plate moves the product to be roughened directly below the laser output component, the laser generator works, and the corresponding place of the product to be roughened is roughened through the laser output head;

[0053] (5). After roughening is completed, the first driving mechanism and the second driving mechanism drive the loading plate and the movable seat to return to their original positions respectively, and then the roughened products can be taken off.

[0054] Similarly, it is possible to select the two laser output components on the left and right to simultaneously perform local and selective roughening processing on two products, or select one of the laser output components to complete the roughening processing of the products on one side.

[0055] The design focus of the present invention lies in: by providing a laser generator and a laser output component, and the laser output component is arranged on the mounting rack so as to be movable back and forth horizontally and connected to the controller, and the laser output component corresponds to the position of the movable plate component, so that the existing plasma roughening is replaced by laser roughening. The laser roughening method does not need to roughen the entire plate surface without difference under high temperature and vacuum environment, effectively reducing the energy consumption of the equipment and lowering the processing cost. Just because it is local and selective roughening, its processing efficiency is higher than that of the non-differential roughening plasma.

[0056] The above is only a preferred embodiment of the present invention, and does not impose any limitation on the technical scope of the present invention. Therefore, any minor modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
