[0064] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and should not be construed as a limitation to the present application.

[0065] In the description of the present invention, it should be understood that with respect to the orientation description, such as the upper, lower, front, rear, left, right, etc., the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0066] The terms "first", "second", "third", "fourth", etc. in the specification and claims of the present invention and the accompanying drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.

[0067] Referring to "embodiment" in the present invention means that the specific features, structures or characteristics described in connection with the embodiment can be included in at least one embodiment of the present invention. The appearance of this phrase at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0068] To meet the needs of contact and soldering of the circuit board, pads need to be provided on the circuit board. At the same time, to protect the circuit board, a protective film also needs to be covered on the circuit board. In order for the protective film not to affect the exposure of the pads, in the prior art, usually, first, according to the size of the pads, openings are made at the corresponding positions on the protective film, and then the protective film after opening is pasted on the circuit board to achieve the protection of the circuit board and the exposure of the positions of the pads. However, using this method is not applicable to some products with high precision requirements, and it is easy to have the problem that the fitting position of the protective film is not precise enough.

[0069] To this end, the embodiments of the present invention provide a method, apparatus, electronic device, and storage medium for manufacturing a circuit board. By using an automatic film laminating device to laminate a protective film on a semi-finished circuit board, the film laminating efficiency can be improved. At the same time, by laminating the protective film first and then performing laser windowing, the accuracy of windowing can be enhanced, avoiding the problem of low film laminating accuracy caused by the method of windowing first and then laminating the film. By using a punching device to punch a substrate to be punched, the substrate to be punched is divided into multiple pre-cutting units, facilitating subsequent division of one substrate into multiple products.

[0070] The following combines the attached Figure 1-8 drawings to describe in detail the method, apparatus, electronic device, and storage medium for manufacturing a circuit board according to the embodiments of the present invention.

[0071] On the one hand, the embodiments of the present invention propose a method for manufacturing a circuit board, as Figure 1 shown, the method includes the following steps:

[0072] Step S100: Obtain a semi-finished circuit board;

[0073] Step S200: Locate a protective film on the semi-finished circuit board through an automatic film laminating device 100;

[0074] Step S300: Perform laser windowing on the protective film of the semi-finished circuit board according to the pad positions of the semi-finished circuit board to expose the pads;

[0075] Step S400: Perform surface treatment on the pads to form a substrate to be punched 700;

[0076] Step S500: Punch the substrate to be punched 700 through a punching device 600 to divide the semi-finished circuit board into multiple pre-cutting units 740.

[0077] It should be noted that the semi-finished circuit board refers to a circuit board that has completed the production of circuits, pads, etc. A protective film needs to be covered on the semi-finished circuit board to protect the semi-finished circuit board.

[0078] As Figure 3 shown, in some embodiments of the present invention, the automatic film laminating device 100 includes a feeding mechanism 200, a separating mechanism 300, a laminating mechanism 400, and a discharging mechanism 500; as Figure 2 shown, the above step S200: The step of laminating a protective film on the semi-finished circuit board through the automatic film laminating device 100 includes the following four steps:

[0079] Step S210: Feed the film to be processed through the feeding mechanism 200; the film to be processed includes a release paper and a protective film provided on the surface of the release paper;

[0080] Step S220: Separate the protective film from the release paper through the separating mechanism 300, and remove the release paper.

[0081] Step S230: Bond the protective film to the semi-finished circuit board through the bonding mechanism 400.

[0082] Step S240: Unload the semi-finished circuit board after film application through the unloading mechanism 500.

[0083] It should be noted that the film to be processed is usually composed of a protective film and a release paper. The protective film is adhered to the release paper, and the release paper plays a role in fixing and protecting the protective film. When applying the protective film to the semi-finished circuit board, the release paper needs to be removed first before the protective film can be applied to the semi-finished circuit board. In the embodiments of the present invention, the automatic film application is realized through the automatic film applicator 100.

[0084] Specifically, as Figure 4 shown, in some embodiments of the present invention, the loading mechanism 200 includes a first feeding table 210, a first moving device 220, and a lifting and adsorption device 230. A limiting device 211 is provided on the first feeding table 210. The first moving device 220 is located above the first feeding table 210, and the lifting and adsorption device 230 is disposed on the first moving device 220. It should be noted that in order for the automatic film applicator 100 to realize automatic film application, the film to be processed needs to be placed on the first feeding table 210 first, and multiple films to be processed can be placed at one time. In this example, the limiting device 211 includes a plurality of limiting columns. By placing the limiting columns around the first feeding table 210, the positioning of the film to be processed can be realized, which is convenient for the lifting and adsorption device 230 to grasp the film to be processed. The first moving device 220 includes a first slide rail arranged in the front-rear direction and a sliding mechanism disposed on the first slide rail. When the sliding mechanism moves along the first slide rail, it can drive the lifting and adsorption device 230 to move back and forth. The lifting and adsorption device 230 includes a lifting assembly and a suction cup. The lifting assembly can adopt devices such as air cylinders to drive the suction cup to move up and down, and the suction cup is used to adsorb the film to be processed. In this example, the above-mentioned step S210: Loading the film to be processed through the loading mechanism 200 includes the following three steps:

[0085] (1) Place a plurality of films to be processed on the first feeding table 210, and limit the plurality of films to be processed through the limiting device 211.

[0086] (2) After the lifting and adsorption device 230 descends and adsorbs the uppermost film to be processed, the lifting and adsorption device 230 lifts and lowers multiple times to shake the adsorbed film to be processed.

[0087] (3) The first moving device 220 drives the lifting and adsorption device 230 to move, so that the lifting and adsorption device 230 transfers the adsorbed film to be processed to the separating mechanism 300.

[0088] It should be noted that after placing multiple films to be processed on the first feeding table 210, the first moving device 230 drives the lifting and adsorbing device 230 to move above the films to be processed. Then, the lifting component of the lifting and adsorbing device 230 drives the suction cup to descend, so that the suction cup adsorbs the topmost film to be processed. After that, the lifting component will drive the suction cup to rise and fall multiple times in place, thereby jittering the adsorbed film to be processed to prevent multiple films to be processed from sticking together, which may cause the suction cup to simultaneously pick up multiple films to be processed at one time. After the lifting and adsorbing device 230 adsorbs one film to be processed, the first moving device 220 drives the lifting and adsorbing device 230 to move towards the separating mechanism 300, and conveys the adsorbed film to be processed to the separating mechanism 300.

[0089] As Figure 5 shown, in some embodiments of the present invention, the separating mechanism 300 includes a conveying platform 310, a second moving device 320, a rotating and lifting device 330, a separating roller 340 with adhesiveness, an aggregate device 350, a receiving platform 360, and a movable grasping device 370. The second moving device 320 is located above the conveying platform 310, the rotating and lifting device 330 is arranged on the second moving device 320, the separating roller 340 is arranged on the rotating and lifting device 330, the aggregate device 350 is arranged between the conveying platform 310 and the receiving platform 360, and the movable grasping device 370 is located above the receiving platform 360. After the lifting and adsorbing device 230 picks up the film to be processed, it will place the film to be processed on the conveying platform 310, and the conveying platform 310 will drive the film to be processed to move towards the direction of the receiving platform 360. When the film to be processed is conveyed to the edge of the conveying platform 310, the film to be processed stops moving. At this time, the second moving device 320 drives the rotating and lifting device 330 to move above the film to be processed. Subsequently, the rotating and lifting device 330 drives the separating roller 340 to descend to the surface of the film to be processed, and the second moving device 320 drives the rotating and lifting device 330 to move back and forth, so that the separating roller 340 rolls back and forth on the surface of the film to be processed. Since the separating roller 340 has adhesiveness, the protective film can be pasted up by the separating roller 340 rolling back and forth on the surface of the film to be processed, so that the protective film is separated from the bottom release paper. Subsequently, the aggregate device 350 receives the release paper, the grasping device 370 moves towards the conveying platform 310, and grabs the protective film onto the receiving platform 360, and the receiving platform 360 performs vacuum adsorption on the protective film. In this example, the above step S220: feeding the film to be processed through the feeding mechanism 200 includes the following three steps:

[0090] (1) The conveying platform 310 obtains the film to be processed conveyed by the feeding mechanism 200, and drives the film to be processed to move towards the receiving platform 360 to a preset position;

[0091] (2) The second moving device 320 drives the rotating and lifting device 330 to move above the film to be processed. The rotating and lifting device 330 drives the separating roller 340 to descend to the surface of the film to be processed. The second moving device 320 drives the separating roller 340 to roll back and forth to separate the release paper from the protective film.

[0092] (3) The collecting device 350 receives the release paper. The gripping device 370 moves towards the conveying platform 310 and grips the protective film onto the receiving platform 360. The receiving platform 360 performs vacuum adsorption on the protective film.

[0093] It should be noted that the gripping device 370 includes a second slide rail arranged in the front-back direction and a clamping jaw arranged on the second slide rail. After the release paper and the protective film are separated, the gripping device 370 will move along the second slide rail close to the protective film. After gripping the protective film through the clamping jaw, it moves back to the receiving platform 360 and places the protective film on the receiving platform 360. The receiving platform 360 is provided with a vacuum adsorption device capable of performing vacuum adsorption on the protective film to prevent the protective film from moving.

[0094] As Figure 5 shown, in some embodiments of the present invention, the collecting device 350 includes a rotating rod 351, a rotating pressure rod (not shown in the figure), a telescopic plate 352, and a collecting frame (not shown in the figure). Among them, rotating plates 353 are respectively arranged at both ends of the rotating rod 351. Both ends of the rotating pressure rod are respectively connected to the two rotating plates. The collecting frame is located below the rotating rod. The telescopic plate 352 is located between the conveying platform 310 and the receiving platform 360. The rotating rod 351 is located between the conveying platform 310 and the telescopic plate 352. In this example, the above steps of: the collecting device 350 receives the release paper, the gripping device 370 moves towards the conveying platform 310 and grips the protective film onto the receiving platform 360, and the receiving platform 360 performs vacuum adsorption on the protective film include the following three steps:

[0095] (1) The rotating plate 353 drives the rotating pressure rod to rotate between the release paper and the protective film, presses down the release paper, and makes the release paper bypass the rotating rod 351.

[0096] (2) The telescopic plate 352 extends to be connected to the conveying platform 310. The rotating rod 351 rotates to convey the release paper into the collecting frame, and the conveying platform 310 conveys the protective film onto the telescopic plate 352.

[0097] (3) The gripping device 370 moves towards the telescopic plate 352 and grips the protective film onto the receiving platform 360. The receiving platform 360 performs vacuum adsorption on the protective film.

[0098] It should be noted that after the release paper and the protective film are separated, the rotating rod 351 will drive the rotating pressure rod to rotate counterclockwise, so that it rotates between the release paper and the protective film, pressing down the release paper so that the release paper is located between the rotating rod 351 and the rotating pressure rod. At this time, when the rotating rod 351 rotates, the release paper will be rolled below by the rotating rod 351 and finally fall into the collection box. Then, the conveying platform 310 conveys the protective film to the telescopic plate 352, and the grasping device 370 moves along the second slide rail to the telescopic plate 352, grabs the protective film through the clamping jaws, and then returns above the material receiving platform 360 and places the protective film on the material receiving platform 360.

[0099] As Figure 6 shown, in some embodiments of the present invention, the laminating mechanism 400 includes: a second feeding table 410, a first manipulator device 420, a third moving device 430, a lamination platform 440, a second manipulator device 450, and a positioning and recognition device (not shown in the figure). The first manipulator device 420 is provided with a first clamping assembly 421 and a second clamping assembly 422. The second manipulator device 450 is provided with a rotatable adsorption assembly 460. The lamination platform 440 is disposed on the third moving device 430. The blanking mechanism 500 includes a blanking platform 510. The blanking platform 510 and the second feeding table 410 are respectively located on both sides of the third moving device 430. Among them, the second feeding table 410 is used to place the semi-finished circuit board; the third moving device 430 can drive the lamination platform 440 to move in the front-rear direction. When the semi-finished circuit board is to be placed on the lamination platform 440, the third moving device 430 moves the lamination platform 440 to one end close to the second feeding table 410. Then, the first clamping assembly 421 will grab the semi-finished circuit board and move it to the lamination platform 440. Then, the third moving device 430 will move the lamination platform 440 to one end close to the second manipulator device 450. The second manipulator device 450 grabs the protective film from the material receiving platform 360 through the adsorption assembly 460. At this time, the material receiving platform 360 stops vacuum adsorption. Then, the second manipulator device 450 drives the adsorption assembly 460 to move above the lamination platform 440 and laminates the protective film on the semi-finished circuit board on the lamination platform 440 to complete the film lamination of the semi-finished circuit board. In this example, the above step S230: laminating the protective film on the semi-finished circuit board through the laminating mechanism 400 includes the following five steps:

[0100] (1) Place the semi-finished circuit board on the second feeding table 410;

[0101] (2) The first manipulator device 420 clamps the semi-finished circuit board to the lamination platform 440 through the first clamping assembly 421;

[0102] (3) The third moving device 430 drives the lamination platform 440 to approach the second manipulator device 450;

[0103] (4) The second manipulator device 450 adsorbs the protective film from the separating mechanism 300 through the adsorption assembly 460, positions the semi-finished circuit board on the pressing platform 440 through the positioning and identification device, and adjusts the position of the protective film through the adsorption assembly 460;

[0104] (5) The second manipulator device 450 presses the protective film on the adsorption assembly 460 onto the semi-finished circuit board.

[0105] It should be noted that in order to ensure the accuracy of the film pasting position, the semi-finished circuit board needs to be positioned through the positioning and identification device before film pasting; at the same time, the adsorption assembly 460 grabs the protective film from the receiving platform 360 and needs to rotate an appropriate angle to exactly paste the protective film on the circuit board.

[0106] In this example, the above-mentioned step S240: discharging the semi-finished circuit board after film pasting through the discharging mechanism 500 includes the following two steps:

[0107] (1) The third moving device 430 drives the pressing platform 440 to approach the discharging platform 510;

[0108] (2) The first manipulator device 420 clamps the semi-finished circuit board without film on the second feeding table 410 through the first clamping assembly 421, and the second clamping assembly 422 places the semi-finished circuit board on the pressing platform 440 on the discharging platform 510. At the same time, the first clamping assembly 421 places the semi-finished circuit board without film on the pressing platform 440.

[0109] It should be noted that the first manipulator device 420 is provided with the first clamping assembly 421 and the second clamping assembly 422. When the first clamping assembly 421 moves above the pressing platform 440, the second clamping assembly 422 is exactly above the discharging platform 510. Through such a setting, when the previous semi-finished circuit board finishes film pasting, the first clamping assembly 421 will grab a semi-finished circuit board without film from the second feeding table 410, and the second clamping assembly 422 will simultaneously grab the semi-finished circuit board that has completed film pasting from the pressing platform 440. Subsequently, the first clamping assembly 421 and the second clamping assembly 422 move to the left together. The first clamping assembly 421 is above the pressing platform 440 and places the semi-finished circuit board without film on the pressing platform 440, and the second clamping assembly 422 is above the discharging platform 510 and places the semi-finished circuit board with film on the discharging platform 510. Through such a setting, the feeding and discharging efficiency of the semi-finished circuit board is greatly improved, thereby improving the production efficiency.

[0110] After the film is applied to the semi-finished circuit board, in order to avoid affecting the connection between the pads of the semi-finished circuit board and external components, it is necessary to perform laser windowing on the protective film of the semi-finished circuit board according to the pad positions of the semi-finished circuit board to expose the pads. Then, it is necessary to perform surface treatment on the pads, such as nickel plating and gold plating, to protect the pads. The finally formed circuit board is the substrate 700 to be die-cut. Subsequently, it is necessary to use a die-cutting device 600 to die-cut the substrate 700 to be die-cut, and divide the substrate 700 to be die-cut into multiple pre-cutting units 740.

[0111] As Figure 7 shown, in some embodiments of the present invention, the die-cutting device 600 includes a frame 610. An elevating platform 620, a die-cutting device 630, and a third loading table 640 are sequentially arranged on the frame 610. A first suction device 650 is arranged above the elevating platform 620, and a second suction device 660 is arranged above the third loading table 640. A positioning device 621 is arranged on the elevating platform 620. Among them, the elevating platform 620 is used to place the substrate 700 to be die-cut, and position the substrate 700 to be die-cut through the positioning device 621. In this example, the positioning device 621 includes positioning pins. The substrate 700 to be die-cut is positioned by passing the positioning pins through the positioning holes (not shown in the figure) of the substrate 700 to be die-cut. After the substrate 700 to be die-cut is placed, the elevating platform 620 rises, facilitating the first suction device 650 to grab the substrate 700 to be die-cut and place it on the die-cutting device 630 for die-cutting. The second suction device 660 is used to place the die-cut substrate 700 to be die-cut on the third loading table 640. In this example, the above step S500: die-cut the substrate 700 to be die-cut through the die-cutting device 600, and divide the substrate 700 to be die-cut into multiple pre-cutting units 740, includes the following four steps:

[0112] (1) Place the substrate to be die-cut on the elevating platform 620 according to the positioning of the positioning device 621;

[0113] (2) The elevating platform 620 rises, and the first suction device 650 sucks the substrate to be die-cut from the elevating platform 620 and places it on the die-cutting device 630;

[0114] After the punching device 630 punches the first area 710 of the substrate to be punched 700 once, the second suction device 660 moves the substrate to be punched 700 by a first preset distance. Then, the punching device 630 punches the first area 710 of the substrate to be punched for the second time to form a plurality of first pre-cutting units. The second suction device 660 moves the substrate to be punched 700 by a second preset distance. After the punching device 630 punches the second area 720 of the substrate to be punched once, the second suction device 660 moves the substrate to be punched 700 by the first preset distance. Then, the punching device 630 punches the second area 720 of the substrate to be punched for the second time to form a plurality of second pre-cutting units. By repeating the above process, a plurality of pre-cutting units 740 are formed.

[0115] (4)The second suction device 660 sucks the plurality of substrates to be punched 700 after punching onto the third discharging table 640.

[0116] As Figure 8 shown, in this example, the substrate to be punched 700 is composed of a plurality of circuit units. Each circuit unit can be used as an individual product. By punching the substrate to be punched, pre-cutting openings 741 can be formed on both sides of each circuit unit, thereby forming a plurality of pre-cutting units 740, which facilitates dividing the entire substrate to be punched 700 into multiple products later. Since the area of the substrate to be punched 700 is relatively large, and the punching die of the punching device 630 can only punch a limited area each time, it is necessary to divide the substrate to be punched 700 into multiple areas, such as Figure 8As shown, in this example, the substrate 700 to be punched is divided into a first region 710, a second region 720, and a third region 730, and each region includes a plurality of circuit units. At the same time, since pre-cutting openings 741 need to be formed on both sides of each circuit unit, and the spacing between both sides of each circuit unit is relatively close, but the spacing between adjacent punching dies of the punching device 630 cannot be too close, therefore, the punching device 630 cannot cut two pre-cutting openings 741 at such a close distance simultaneously. For this reason, after the punching device 630 punches the first region 710 of the substrate 700 to be punched once, pre-cutting openings 741 will be formed on one side of each circuit unit in the first region 710. Then, the second suction device 660 moves the substrate 700 to be punched a first preset distance (the first preset distance is equal to the spacing between the pre-cutting openings on both sides of a circuit unit), so that the punching device 630 punches the first region 710 of the substrate 700 to be punched a second time, thereby forming pre-cutting openings 741 on the other side of each circuit unit in the first region 710. By punching twice, pre-cutting openings 741 are formed on both sides of each pre-cutting unit 740 in the first region 710. Subsequently, the second suction device 660 moves the substrate 700 to be punched a second preset distance (the second preset distance is equal to the spacing between adjacent regions), and the punching device 630 punches the second region 720 of the substrate 700 to be punched twice. The punching process is the same as that of the first region 710, thereby forming a plurality of second pre-cutting units; repeating the above process, a plurality of pre-cutting units are formed to complete the punching of the substrate 700 to be punched.

[0117] According to the method for manufacturing a circuit board of an embodiment of the present invention, by using the automatic film laminating device 100 to laminate a protective film on the semi-finished circuit board, the film laminating efficiency can be improved. At the same time, by laminating the protective film first and then performing laser windowing, the accuracy of windowing can be improved, and the problem of low film laminating accuracy caused by the method of windowing first and then laminating the film can be avoided; by using the punching device 600 to punch the substrate 700 to be punched, the substrate 700 to be punched is divided into a plurality of pre-cutting units 740, which is convenient for subsequently dividing one substrate into a plurality of products.
