[0002] Flexible printed circuit boards (FPCs) are widely used in consumer electronics, automotive electronics, and medical devices due to their advantages such as flexibility, small size, and lightweight. Because FPCs have fine lines and flexible substrates, they are prone to quality problems such as line defects, residual copper, short circuits, and open circuits during the manufacturing process. Therefore, comprehensive appearance and electrical performance testing before shipment is crucial.

[0003] In existing production processes, automated optical inspection (AOI) of FPCs generally adopts an offline inspection method, which involves collecting the boards from the production line and transporting them to independent inspection equipment. Offline inspection is prone to scratches, oxidation, or dust contamination on the board surface due to contact and exposure during board collection, transfer, and reloading.

[0023] Please see Figures 1-2 As shown, Figure 1 This is a cross-sectional schematic diagram of an embodiment of the online double-sided inspection system provided in this application; Figure 2 This is a top view schematic diagram of an embodiment of the online double-sided inspection system provided in this application; the online double-sided inspection system 1 of this embodiment includes an edge-aligning machine component 10, a conveying component 30, a first imaging component 40, a second imaging component 50, and a coding component 60.

[0024] The edge-aligning assembly 10 is connected to the etching line and is used to receive the flexible circuit board (not shown) conveyed by the etching line (not shown in the figure) and to align the flexible circuit board to the edge. The edge-aligning is achieved by pushing the flexible circuit board through the edge-aligning assembly 10, so that the flexible circuit board is attached and aligned with the preset reference edge of the edge-aligning assembly 10.

[0025] Optionally, the number of flexible circuit boards received by the edge-aligning assembly 10 from the etching line includes, but is not limited to, one or two boards. For example, the etching line may simultaneously transport two flexible circuit boards at a time, with the front-to-back distance and left-to-right distance between the two flexible circuit boards not fixed, and the size of the flexible circuit boards also not fixed.

[0026] In some embodiments, after the flexible circuit board is developed, etched, and peeled off by etching lines, the position of the flexible circuit board when it is transported to the edge-aligning machine assembly 10 is random, such as front-back or left-right positions are not fixed. The edge-aligning machine assembly 10 moves the flexible circuit board to the edge, which facilitates subsequent imaging and coding.

[0027] The conveying assembly 30 is connected to the edge-aligning assembly 10 and is used to convey the flexible circuit board. The first imaging assembly 40 is positioned above the conveying assembly 30 and on the side of the edge-aligning assembly 10 away from the etching lines, and is used to acquire a first image of the upper surface of the flexible circuit board. The second imaging assembly 50 is positioned below the conveying assembly 30 and on the side of the first imaging assembly 40 away from the edge-aligning assembly 10, and is used to acquire a second image of the lower surface of the flexible circuit board. The conveying method of the conveying assembly 30 includes, but is not limited to, vacuum suction belt conveying.

[0028] In some embodiments, after the flexible circuit board is aligned with the edge by the edge-aligning assembly 10, it is conveyed at a constant speed to the first imaging assembly 40 by the conveying assembly 30. At this time, the flexible circuit board is located between the first imaging assembly 40 and the conveying assembly 30. The first imaging assembly 40 acquires a first image from the upper surface of the flexible circuit board located below, and then conveys it to the second imaging assembly 50 through the conveying assembly 30. The flexible circuit board is located between the conveying assembly 30 and the second imaging assembly 50. The second imaging assembly 50 acquires a second image from the lower surface of the flexible circuit board located above.

[0029] The coding component 60 is disposed above the conveying component 30 and is located on the side of the second imaging component 50 away from the first imaging component 40. It is used to mark and encode the flexible circuit board. The end of the conveying component 30 near the coding component 60 is connected to the downstream equipment (not shown). The flexible circuit board is conveyed to the downstream equipment through the conveying component 30.

[0030] In some embodiments, after the flexible circuit board has its image acquired by the first imaging component 40 and the second imaging component 50, it is transported to the coding component 60 via the conveying component 30. The coding component 60 uses one or two coding systems to mark and encode the flexible circuit board for easy identification in the future. After passing through the coding component 60, the flexible circuit board enters the downstream processing equipment, such as a board collecting machine, to collect the flexible circuit board.

[0031] The online double-sided inspection system 1 of this embodiment includes an edge-aligning machine component 10, a conveying component 30, a first imaging component 40, a second imaging component 50, and a coding component 60. By integrating edge alignment, double-sided image acquisition, and coding marking functions into a continuous online double-sided inspection system 1, and directly connecting it with the etching line and subsequent process equipment, a fully automatic and uninterrupted inspection closed loop is formed. For example, the conveying component 30 is connected to the board receiving machine. Compared with offline inspection methods, it avoids secondary defects such as board scratches, pressure marks, oxidation, and dust contamination that may occur during board receiving, handling, and secondary loading, greatly improving the accuracy and reliability of the inspection results. At the same time, the coordinated layout of the first imaging component 40 and the second imaging component 50 enables simultaneous double-sided inspection to be completed in a single pass, significantly improving production efficiency and product yield.

[0032] According to some embodiments of this application, see Figure 3 and Figure 4 As shown, Figure 3 This is a top view schematic diagram of an embodiment of the edge-aligning machine component provided in this application; Figure 4 This is a schematic diagram of the structure of an embodiment of the edge-keeping machine component provided in this application; the edge-keeping machine component 10 of this embodiment includes a frame 11, a first edge-keeping component 12 and a second edge-keeping component 13.

[0033] The first edge-adjusting component 12 and the second edge-adjusting component 13 are disposed opposite to each other on the frame 11. One end of the first edge-adjusting component 12 and one end of the second edge-adjusting component 13 are both connected to the etching line. The first edge-adjusting component 12 is used to receive the flexible circuit board conveyed by the etching line and to edge the flexible circuit board. The second edge-adjusting component 13 is used to receive the flexible circuit board conveyed by the etching line and to edge the flexible circuit board.

[0034] In some embodiments, the etching line simultaneously delivers two flexible circuit boards at a time. The positions of the two flexible circuit boards are random. The two flexible circuit boards are aligned with each other by the first edge-aligning component 12 and the second edge-aligning component 13, respectively. That is, the first edge-aligning component 12 and the second edge-aligning component 13 push the two flexible circuit boards respectively, and the flexible circuit boards are aligned with the corresponding preset reference edge.

[0035] The preset reference edge of the first edge component 12 is located on the side away from the second edge component 13, and the preset reference edge of the second edge component 13 is located on the side away from the first edge component 12.

[0036] This embodiment forms a parallel processing channel by setting up a first edge-aligning component 12 and a second edge-aligning component 13 that are positioned opposite each other and directly connected to the etching line. This allows the online double-sided inspection system 1 to simultaneously receive and process two flexible circuit boards delivered from the etching line in parallel. This not only effectively matches the dual-board output rhythm of the upstream etching line and significantly shortens the average processing cycle of a single board, greatly improving the overall inspection efficiency and productivity, but also ensures that each flexible circuit board can obtain accurate and stable initial positioning through parallel independent edge-aligning operations, laying a unified and reliable benchmark for subsequent double-sided visual inspection.

[0044] In some embodiments, the first side-mounted component 12 further includes a first drive motor 128, which is disposed on the side of the first support plate 121 away from the plurality of first rollers 122. The first drive motor 128 is used to drive the plurality of first rollers 122 via a first drive belt 124.

[0045] The first drive motor 128 includes, but is not limited to, a stepper motor, a servo motor, or a speed-regulating motor, and the first drive belt 124 includes, but is not limited to, a round belt, a synchronous belt, a V-belt, or a chain.

In conjunction with the continuous forward movement of the first flat belt 126, one side of the flexible circuit board is fixed at the position of the first flat belt 126, thereby positioning the flexible circuit board and achieving the goal of moving it to the side.

The flexible circuit board is obliquely transported by the plurality of second rollers 132, and the flexible circuit board is attached and aligned with the second flat belt 136 to achieve edge alignment.

[0059] In some embodiments, a plurality of first row rollers 122 correspond one-to-one with a plurality of second row rollers 132, and the plurality of first row rollers 122 and the plurality of second row rollers 132 are arranged obliquely toward each other. At this time, the plurality of first row rollers 122 and the plurality of second row rollers 132 are arranged in a V-shape. The speed of the first row rollers 122 and the second row rollers 132 is greater than or equal to the conveying speed of the etching line, and the included angle formed between the first row rollers 122 and the corresponding second row rollers 132 is between 110° and 145°. During the conveying process of the two flexible circuit boards, the two flexible circuit boards move toward the first flat belt 126 and the second flat belt 136 respectively, thereby achieving the purpose of moving to the edge.

[0060] For example Figure 3 As shown, the first side-mounted component 12 includes 16 first row rollers 122, and the second side-mounted component 13 includes 16 second row rollers 132.

[0061] In some embodiments, the first edge-keeping assembly 12 further includes a first protective cover 129 disposed on the first mounting plate 125; the second edge-keeping assembly 13 further includes a second protective cover 139 disposed on the second mounting plate 135; the edge-keeping machine assembly 10 further includes a speed adjuster 14 disposed on the frame 11 for adjusting the running speed of the first roller 122, the second roller 132, the first flat belt 126 and the second flat belt 136.

[0062] In this embodiment, the first edge-adjusting component 12 and the second edge-adjusting component 13 can be independently controlled by a speed adjuster.

[0063] This embodiment achieves the function of two rows simultaneously moving to the side through the first row roller 122 and the second row roller 132, eliminating the need for a push plate mechanism and avoiding scratching the surface of the flexible circuit board.

The first vacuum chamber 316 is located on the side of the first conveyor belt 314 away from the first imaging assembly 40. The third drive motor 315 is connected to the first drive roller 313.

[0069] The first conveyor belt 314 includes, but is not limited to, a perforated conveyor belt. In this embodiment, the first conveyor belt 314 is a non-elastic flat belt with guide strips and a thickness of 0.5mm to 3mm. The surface is perforated, the perforations are arranged in a matrix, the spacing between the perforations is 5mm to 30mm, the perforation size is 1mm to 5mm, and the color is black or green.

[0070] The first passive roller 311 is used to support the first conveyor belt 314. The first passive roller 311 is a cylindrical or drum-shaped solid or hollow shaft with a diameter of 30mm to 60mm. The first tension roller 312 is used to support and tension the first conveyor belt 314. The first tension roller 312 is a cylindrical or drum-shaped solid or hollow shaft with a diameter of 30mm to 60mm. Both ends of the first tension roller 312 are floating and adjustable. The first drive roller 313 is used to support and drive the first conveyor belt 314. One end of the first drive roller 313 is connected to the third drive motor 315. The first drive roller 313 is a cylindrical or drum-shaped solid or hollow shaft with a diameter of 30mm to 60mm.

[0071] In other embodiments, the first tensioning roller 312 may be combined with the first passive roller 311 into a single roller.

[0072] The first vacuum chamber 316 is used to provide negative pressure adsorption pressure.

[0073] In some embodiments, the flexible circuit board enters the first conveying assembly 31 and is brought into close contact with the first conveyor belt 314 by the first vacuum box 316.

[0074] like Figure 5 As shown, the first imaging component 40 includes a first support frame 41, a first imaging element 42, a second imaging element 43, a first lighting component 44, a first lifting motor 45, a first roller assembly 46, and a second roller assembly 47. The first support frame 41 is disposed above the first conveyor belt 314. The first roller assembly 46 and the second roller assembly 47 are spaced apart on the first support frame 41. The first lighting component 44 is disposed on the first support frame 41 and is located above the first roller assembly 46 and the second roller assembly 47. The first imaging element 42 and the second imaging element 43 are spaced apart on the first support frame 41 and are located above the first lighting component 44. The first lifting motor 45 is disposed on the first support frame 41.

[0075] The first lifting motor 45 is used to drive the first support frame 41 to move up and down. The first lifting motor 45 includes, but is not limited to, a servo motor, a stepper motor, or a speed-regulating motor. The first lighting component 44 is used to illuminate the flexible circuit board. The first lighting component 44 includes 3 to 6 sets of LED strip lights. The light colors include, but are not limited to, red, blue, and white. The first lighting component 44 can adjust the angle or height.

[0076] The first roller assembly 46 and the second roller assembly 47 are used to assist in leveling the flexible circuit board. The first roller assembly 46 and the second roller assembly 47 include, but are not limited to, a whole PP roller, spaced PP wheels or other spaced rolling elements. The diameter of the first roller assembly 46 and the second roller assembly 47 is between 10mm and 50mm.

[0077] In this embodiment, both the first imaging element 42 and the second imaging element 43 are composed of 2 to 6 groups of imaging elements (not shown in the figure). For example Figure 6 As shown, both the first imaging element 42 and the second imaging element 43 are composed of 3 imaging elements.

[0078] In some embodiments, since the thickness of the flexible circuit board is relatively small, the first imaging component 40 stores preset height data (obtained according to the thickness of the flexible circuit board). When the two flexible circuit boards pass the edge-aligning assembly 10, the first lifting motor 45 drives the first support frame 41 to move up and down to a suitable height according to the preset height data. When the two flexible circuit boards are transported side by side to the first imaging component 40 via the first conveyor belt 314, the first roller assembly 46 and the second roller assembly 47 flatten the flexible circuit board and make the flexible circuit board stick tightly to the first conveyor belt 314 (the first vacuum box 316 provides negative pressure adsorption pressure). The first light assembly 44 illuminates the flexible circuit board, and the first imaging element 42 and the second imaging element 43 respectively acquire images of the two flexible circuit boards.

[0079] This embodiment ensures the flatness of the flexible circuit board when acquiring images by setting the first roller assembly 46 and the second roller assembly 47, improves the accuracy of acquiring the first image of the upper surface of the flexible circuit board, and realizes dual-row acquisition of the flexible circuit board by the first imaging element 42 and the second imaging element 43, thereby improving the detection efficiency.

[0080] like Figure 7 As shown, the second conveying assembly 32 includes a first passive tension roller 321, a second drive roller 322, a second conveyor belt 323, and a fourth drive motor 324. The first passive tension roller 321 and the second drive roller 322 are connected by the second conveyor belt 323, and the fourth drive motor 324 is connected to the second drive roller 322.

[0081] The third conveying assembly 33 includes a second passive tension roller 331, a third drive roller 332, a third conveyor belt 333, and a fifth drive motor 334. The second passive tension roller 331 and the third drive roller 332 are connected by the third conveyor belt 333, and the fifth drive motor 334 is connected to the third drive roller 332.

[0082] The second conveyor belt 323 and the third conveyor belt 333 have the same structure as the first conveyor belt 314 in the above embodiment. The first passive tension roller shaft 321 and the second passive tension roller shaft 331 have the same structure as the first tension roller shaft 312 in the above embodiment. The second drive roller shaft 322 and the third drive roller shaft 332 have the same structure as the first drive roller shaft 313 in the above embodiment. They will not be described again here.

[0083] The fourth conveying assembly 34 includes a second support frame 341, a second passive roller 342, a second tension roller 343, a fourth drive roller 344, a fourth conveyor belt 345, a sixth drive motor 346, a second vacuum box 347, and a second lifting motor 348. The second passive roller 342, the second tension roller 343, and the fourth drive roller 344 are mounted on the second support frame 341 and connected by the fourth conveyor belt 345. The sixth drive motor 346 is connected to the fourth drive roller 344. The second vacuum box 347 is located on the side of the fourth conveyor belt 345 away from the second imaging assembly 50. The second lifting motor 348 is mounted on the second support frame 341.

[0084] The second support frame 341, the second passive roller 342, the second tension roller 343, the fourth drive roller 344, the fourth conveyor belt 345, the sixth drive motor 346, the second vacuum box 347, and the second lifting motor 348 are structurally identical to the first support frame 41, the first passive roller 311, the first tension roller 312, the first drive roller 313, the first conveyor belt 314, the third drive motor 315, the first vacuum box 316, and the first lifting motor 45 in the above embodiment, and will not be described in detail here.

[0085] In some embodiments, the conveying assembly 30 further includes a negative pressure fan 35, which is disposed on the frame 11 of the side-mounting assembly 10 and located below the first side-mounting assembly 12 and the second side-mounting assembly 13. The first vacuum box 316 and the second vacuum box 347 are connected to the negative pressure fan 35 through pipes.

[0086] like Figure 7 As shown, the second imaging assembly 50 includes a bridge support plate 51, a third roller assembly 52, a fourth roller assembly 53, a second light assembly 54, a third imaging element 55, and a fourth imaging element 56. The bridge support plate 51 is disposed below the fourth conveyor belt 345 and between the second conveyor belt 323 and the third conveyor belt 333. The third roller assembly 52 and the fourth roller assembly 53 are spaced apart on the bridge support plate 51. The second light assembly 54 is disposed on the bridge support plate 51 and is located below the third roller assembly 52 and the fourth roller assembly 53. The third imaging element 55 and the fourth imaging element 56 are spaced apart on the bridge support plate 51 and are located below the second light assembly 54.

[0087] Among them, the bridge support plate 51 is used to support the third roller shaft assembly 52 and the fourth roller shaft assembly 53, and to prevent the flexible circuit board from falling off. The bridge support plate 51 has a certain degree of flatness.

[0088] The third roller assembly 52 and the fourth roller assembly 53 are used to flatten the flexible circuit board, so that the flexible circuit board is in close contact with the fourth conveyor belt 345. The third roller assembly 52 and the fourth roller assembly 53 include smooth rollers with a diameter of 10mm to 50mm, including but not limited to a single integral roller or a separately moving roller. The third roller assembly 52 and the fourth roller assembly 53 have a certain elasticity. The surfaces of the third roller assembly 52 and the fourth roller assembly 53 are coated with adhesive, and the adhesive material includes but is not limited to polyurethane or rubber.

[0089] The second lighting assembly 54, the third imaging element 55, and the fourth imaging element 56 have the same structure as the first lighting assembly 44, the first imaging element 42, and the second imaging element 43 in the above embodiments, and will not be described again here.

[0090] In some embodiments, since the flexible circuit board is relatively thin, the second imaging component 50 stores preset height data (obtained based on the thickness of the flexible circuit board). When the two flexible circuit boards pass the edge-aligning assembly 10, the second lifting motor 348 drives the second support frame 341 to move up and down to a suitable height according to the preset height data, so that the two flexible circuit boards are transported to the fourth conveyor belt 345 via the second conveyor belt 323. The second vacuum box 347 makes the flexible circuit board fit tightly against the fourth conveyor belt 345. When the flexible circuit board is transported to the second imaging component 50, the third roller assembly 52 and the fourth roller assembly 53 flatten the flexible circuit board (the elasticity of the third roller assembly 52 and the fourth roller assembly 53 can overcome gravity and stabilize the flexible circuit board on the fourth conveyor belt 345). The second light assembly 54 illuminates the flexible circuit board, and the third imaging element 55 and the fourth imaging element 56 respectively acquire images of the two flexible circuit boards.

[0091] This embodiment ensures the flatness of the flexible circuit board when acquiring images by setting the third roller assembly 52 and the fourth roller assembly 53, thereby improving the accuracy of acquiring the second image of the lower surface of the flexible circuit board.

[0092] According to some embodiments of this application, see Figure 2 As shown, the online double-sided inspection system 1 also includes a thickness measuring component 20, an industrial control computer 70, and an electrical control system 80. The thickness measuring component 20 is located between the edge-mounting machine component 10, the conveying component 30, and the first imaging component 40. The thickness measuring component 20 is used to collect thickness data of the flexible circuit board. The industrial control computer 70 is located below the thickness measuring component 20, and the electrical control system 80 is located below the inkjet printing component 60.

[0093] Optionally, the thickness measurement component 20 may collect thickness data of the flexible circuit board in ways including but not limited to mechanical pressure thickness measurement or laser non-contact thickness measurement.

[0094] In some embodiments, after the flexible circuit board is thickness-measured by the thickness measuring component 20, it is conveyed at a constant speed to the first imaging component 40 via the conveying component 30. At this time, the flexible circuit board is located between the first imaging component 40 and the conveying component 30. The first imaging component 40 acquires a first image of the upper surface of the flexible circuit board below based on the thickness data transmitted by the thickness measuring component 20. Then, it is conveyed to the second imaging component 50 via the conveying component 30. The flexible circuit board is located between the conveying component 30 and the second imaging component 50. The second imaging component 50 acquires a second image of the lower surface of the flexible circuit board above based on the thickness data transmitted by the thickness measuring component 20.

[0095] In some embodiments, when two flexible circuit boards pass through the thickness measuring component 20, the thickness measuring component 20 transmits the thickness data to the first lifting motor 45. The first lifting motor 45 drives the first support frame 41 to move up and down to a preset height (calculated based on the thickness data) according to the thickness data. When the two flexible circuit boards are transported side by side to the first imaging component 40 via the first conveyor belt 314, the first roller assembly 46 and the second roller assembly 47 flatten the flexible circuit boards and make the flexible circuit boards stick tightly to the first conveyor belt 314 (the first vacuum box 316 provides negative pressure adsorption pressure). The first light assembly 44 illuminates the flexible circuit boards, and the first imaging element 42 and the second imaging element 43 respectively acquire images of the two flexible circuit boards.

[0096] The electronic control system 80 is used for motion control of the edge-mounting machine component 10, thickness measuring component 20, first imaging component 40, second imaging component 50 and inkjet printing component 60; the industrial control computer 70 is used to process thickness data and images acquired by the first imaging component 40 and the second imaging component 50.

[0097] In some embodiments, the online double-sided inspection system 1 further includes auxiliary functional systems such as an electrostatic discharge system (not shown), a heat dissipation system (not shown), a lubrication system (not shown), a dust extraction system (not shown), and a cooling water circulation system (not shown). The electrostatic discharge system is used to remove static electricity from the flexible circuit board; the heat dissipation system is used to dissipate heat from the first imaging component 40, the second imaging component 50, and the electronic control system 80; the lubrication system is used to provide lubrication; the dust extraction system is used to remove dust, particulate matter, and other contaminants; and the cooling water circulation system is used to dissipate heat from the first lighting component 44 and the second lighting component 54.
