Description

Technical Field

[0001] This utility model relates to a flexible stage device suitable for FPC visual inspection, and in particular to a flexible stage device suitable for FPC visual inspection, belonging to the technical field of flexible stage devices for FPC visual inspection. Background Technology

[0002] Flexible printed circuit boards (FPCs), also known as flexible circuit boards or flexographic circuit boards, are highly favored in the electronics field due to their excellent characteristics such as light weight, thinness, and ability to be freely bent and folded. They are widely used in many fields such as smartphones, aerospace, and military for connecting components and motherboards, such as display modules and fingerprint modules. As electronic products develop towards high density, miniaturization, and high reliability, the use of FPCs continues to increase. In the FPC production process, appearance inspection is an important step, which needs to check for indentations, foreign objects, poor dispensing, etc. Traditional inspection methods are mostly human eye inspection, but in recent years, visual inspection has also been gradually applied. However, regardless of the inspection method, the FPC needs to be placed on a suitable platform for inspection.

[0003] Traditional flexible stage devices for FPC visual inspection have a simple structure and existing FPC visual inspection stages have several problems. On the one hand, FPC material is soft, and improper handling during placement and fixing can easily scratch the surface of the circuit board, causing damage to the internal circuitry and resulting in product waste. On the other hand, traditional stages usually require corresponding fixing fixtures for FPCs of different sizes, which not only increases the cost of fixtures but also makes the replacement process more troublesome, affecting inspection efficiency. In addition, if the stage cannot fix and support the FPC well during inspection, it may cause the FPC to bend or deform, thereby affecting the accuracy of the inspection results and leading to false tests.

[0004] Therefore, there is an urgent need to improve a flexible stage device suitable for FPC visual inspection in order to solve the above-mentioned problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-7 As shown in the figure, this embodiment provides a flexible stage device suitable for FPC appearance inspection.

[0027] A flexible stage device for FPC visual inspection includes a base plate 1 and a vertical plate 2. An FPC body 3 is fixedly mounted on one end of the base plate 1. A vacuum adsorption structure 4 is provided on the base plate 1. The vacuum adsorption structure 4 includes a vacuum pump 5 fixedly mounted on the top of the base plate 1. Multiple first connecting pipes 6 are fixedly mounted on the vacuum pump 5, and a second connecting pipe 7 is fixedly mounted on one end of each first connecting pipe 6. A flexible stage body 8 is fixedly mounted on the top of the FPC body 3. The flexible stage body 8 has grooves 9 and multiple suction holes 10. A vacuum nozzle 11 is mounted on the bottom of the flexible stage body 8, and a connector 12 connected to the second connecting pipe 7 is fixedly mounted on the bottom of the vacuum nozzle 11. A spring clamp 13 is fixedly mounted on one end of the flexible stage body 8, and a positioning pin 14 connected to the vertical plate 2 is provided on the spring clamp 13.

[0028] A first fixing plate 15 is fixedly installed on one side of the FPC body 3. A rotating rod 16 is movably installed on the top of the first fixing plate 15. A first gear 17 is fixedly installed below the rotating rod 16. A drive motor 18 is fixedly installed on the first fixing plate 15. A second gear 19 that meshes with the first gear 17 is fixedly installed at the output end of the drive motor 18. A first connecting block 20 is fixedly installed on the top of the rotating rod 16. A first electric telescopic rod 21 is fixedly installed at one end of the first connecting block 20. A second connecting block 22 is installed at the output end of the first electric telescopic rod 21. A second electric telescopic rod 23 is fixedly installed at the bottom of the second connecting block 22. An FPC suction cup 24 connected to the upright plate 2 is fixedly installed at the output end of the second electric telescopic rod 23. A control panel 25 is provided on one side of the flexible platform body 8.

[0029] By using the vacuum adsorption structure 4, the traditional method of manually placing FPCs during thermal inspection is changed. This avoids scratches on the circuit board surface and damage to internal circuits caused by operators during FPC placement. When visual inspection of the FPC begins, the drive motor 18 is started via the control panel 25, driving the second gear 19. Due to the connection between the second gear 19 and the first gear 17, the first gear 17 also rotates simultaneously with the second gear 19. The rotating rod 16 also rotates under the drive of the first gear 17. The rotation of the rotating rod 16 allows for angle adjustment of the first connecting block 20. Adjusting the first connecting block 20 allows for adjustment of a series of structures at one end, including the first electric telescopic rod 21, the second connecting block 22, the second electric telescopic rod 23, and the FPC suction cup 24.

[0030] After the FPC suction cup 24 has finished adsorbing the upright plate 2 from the conveying device, the upright plate 2 adsorbed on the FPC suction cup 24 can be moved back above the flexible platform body 8 by resetting and adjusting the first connecting block 20. Then, by starting the second electric telescopic rod 23 on the control panel 25, the FPC suction cup 24 will descend until the upright plate 2 adsorbed on the FPC suction cup 24 is placed into the groove 9 opened on the flexible platform body 8. The operation of the second electric telescopic rod 23 will then stop. After the upright plate 2 is placed, the positioning pin 14 can initially clamp one end of the upright plate 2 under the elastic action of the spring clamp 13.

[0031] After the vacuum nozzle 11 is attached to the bottom of the flexible platform body 8 and covers the multiple air extraction holes 10, the vacuum pump 5 can be started via the control panel 25 to perform vacuuming. The multiple first connecting pipes 6 on the vacuum pump 5 can all connect to the second connecting pipes 7 and are connected to the connector 12 to extract air from inside the vacuum nozzle 11. This allows the vacuum nozzle 11 to generate a certain suction force on the upright plate 2 through the multiple air extraction holes 10 on the flexible platform body 8. Since the pipes of the first connecting pipes 6 can be opened or closed, the suction force of the vacuum nozzle 11 can reach its maximum when all the first connecting pipes 6 are open. Therefore, it can firmly adsorb the FPC and prevent movement. Simultaneously, to accommodate FPCs of different strengths, closing one or more of the first connecting tubes 6 reduces the suction force of the vacuum nozzle 11. This ensures firm adsorption of the FPC while preventing deformation or damage due to excessive suction. This design ensures the FPC remains relatively flat and stable during inspection, laying the foundation for high-quality imaging. The advantages of this structure include simplified FPC replacement without affecting inspection efficiency, and the ability to effectively fix and support the FPC while preventing bending or deformation.

[0032] like Figures 1-7 As shown, a protective shell 26 is fixedly installed on the outside of the drive motor 18. The protective shell 26 has multiple heat dissipation holes 27. A maintenance cover 28 is provided at one end of the protective shell 26. A first magnetic ring 29 is fixedly installed on the inner side of the maintenance cover 28. A second magnetic ring 30, which is magnetically connected to the first magnetic ring 29, is fixedly installed on the protective shell 26.

[0033] The protective shell 26, heat dissipation holes 27, and inspection cover 28 effectively protect the drive motor 18 from impact damage. The multiple heat dissipation holes 27 on the protective shell 26 dissipate the heat generated by the drive motor 18, preventing overheating and potential malfunction. The inspection cover 28 allows for easy maintenance of the drive motor 18 without disassembling the protective shell 26, saving time. The first magnetic ring 29 and the second magnetic ring 30 attract each other, securing the inspection cover 28 to one end of the protective shell 26 and preventing it from falling off. Due to the characteristics of the first magnetic ring 29 and the second magnetic ring 30, the inspection cover 28 can be opened by simply pulling it without tools, further saving time.

[0034] like Figures 1-7As shown, a first fixing block 31 is fixedly installed on the first electric telescopic rod 21, and a first fixing sleeve 32 connected to the first fixing block 31 is fixedly installed on the second connecting block 22. Both the first fixing block 31 and the first fixing sleeve 32 are provided with connecting holes 33. An insert rod 34 is movably installed inside the connecting hole 33, and a latch 35 is fixedly installed at one end of the insert rod 34.

[0035] With the arrangement of the first fixing block 31, the first fixing sleeve 32, the connecting hole 33, the insert rod 34, and the latch 35, the first fixing block 31 is inserted into the first fixing sleeve 32, and then the insert rod 34 is inserted into the connecting hole 33 to connect the two together. Then, the insert rod 34 is rotated so that the angle of the latch 35 is adjusted to be perpendicular to the angle of the connecting hole 33, thus fixing the first fixing block 31 inside the first fixing sleeve 32 to prevent it from falling off. When the insert rod 34 is rotated in the opposite direction so that the angle of the latch 35 is consistent with the angle of the connecting hole 33, the insert rod 34 can be pulled out from the inside of the connecting hole 33, thereby allowing the first fixing block 31 to be pulled out from the inside of the first fixing sleeve 32. Therefore, it is convenient for personnel to disassemble and replace the insert rod 34 when it is damaged.

[0036] like Figures 1-7 As shown, a second fixing plate 36 is fixedly installed on the top of the second connecting block 22. A third electric telescopic rod 37 is fixedly installed on one side of the second fixing plate 36. A locking tooth 38 is installed at the output end of the third electric telescopic rod 37. A toothed ring 39 that meshes with the locking tooth 38 is fixedly installed at the other end of the insertion rod 34. A second fixing block 40 is fixedly installed on the third electric telescopic rod 37. A second fixing sleeve 41 that connects to the second fixing block 40 is fixedly installed at one end of the locking tooth 38. A plurality of mounting holes 42 are provided on the second fixing block 40. A spring body 43 is fixedly installed inside the mounting holes 42. A locking ball 44 is fixedly installed at one end of the spring body 43. A plurality of locking holes that cooperate with the locking ball 44 are provided on the inner side of the second fixing sleeve 41.

[0037] With the arrangement of the second fixing plate 36, the third electric telescopic rod 37, the locking teeth 38, and the toothed ring 39, when the insertion rod 34 is inserted into the connecting hole 33 to connect the first fixing block 31 and the first fixing sleeve 32, the third electric telescopic rod 37 is activated via the control panel 25 to extend, causing the locking teeth 38 to move. When the locking teeth 38 move to the position of the toothed ring 39 and engage with it, the insertion rod 34 can be fixed and limited, thus preventing the insertion rod 34 from rotating and affecting the stability of the first fixing block 31 inside the first fixing sleeve 32. When the third electric telescopic rod 37 retracts, it can cause the locking teeth 38 to disengage from the toothed ring 39, thereby allowing the insertion rod 34 to rotate normally. The arrangement of the fixing block 40, the second fixing sleeve 41, the mounting hole 42, the spring body 43, the locking ball 44, and the locking hole allows the locking ball 44 to be compressed and contracted into the mounting hole 42 during the process of inserting the second fixing block 40 into the second fixing sleeve 41. When the locking ball 44 moves to the position of the locking hole, it can pop out and lock into the locking hole under the elastic action of the spring body 43, thereby fixing the second fixing block 40 inside the second fixing sleeve 41 to prevent it from falling off. Pulling the locking tooth 38 causes the locking ball 44 to be compressed and contracted into the mounting hole 42. After the locking ball 44 is disengaged from the locking hole, the locking tooth 38 can be removed from the third electric telescopic rod 37, making it convenient for personnel to disassemble and replace the locking tooth 38 when it is damaged.

[0038] In this embodiment, as Figures 1-6 As shown in the figure, the working process of the flexible stage device for FPC appearance inspection provided in this embodiment is as follows:

[0039] When the visual inspection of the FPC begins, the drive motor 18 is first started via the control panel 25, driving the second gear 19 to operate. Due to the connection between the second gear 19 and the first gear 17, the first gear 17 also begins to rotate simultaneously with the second gear 19. The rotating rod 16 also begins to rotate under the drive of the first gear 17. The rotation of the rotating rod 16 allows for angle adjustment of the first connecting block 20. Adjusting the first connecting block 20 allows for adjustment of a series of structures at one end, including the first electric telescopic rod 21, the second connecting block 22, the second electric telescopic rod 23, and the FPC suction cup 24. After the suction cup 24 picks up the upright plate 2 from the conveying device, the upright plate 2 picked up by the suction cup 24 can be moved back to above the flexible platform body 8 by resetting and adjusting the first connecting block 20. Then, by starting the second electric telescopic rod 23 on the control panel 25, the suction cup 24 will be lowered until the upright plate 2 picked up by the suction cup 24 is placed into the groove 9 opened on the flexible platform body 8. The second electric telescopic rod 23 will then stop. After the upright plate 2 is placed, the positioning pin 14 can initially clamp one end of the upright plate 2 under the elastic action of the spring clamp 13.

[0040] After the vacuum nozzle 11 is attached to the bottom of the flexible stage body 8 and covers the multiple air extraction holes 10, the vacuum pump 5 can be started via the control panel 25 to perform vacuuming. The multiple first connecting pipes 6 on the vacuum pump 5 can be connected to the second connecting pipes 7 and connected to the connector 12 to extract the air inside the vacuum nozzle 11. This allows the vacuum nozzle 11 to generate a certain suction force on the upright plate 2 through the multiple air extraction holes 10 on the flexible stage body 8. Since the pipes of the first connecting pipes 6 can be opened or closed, when all the first connecting pipes 6 are open, the suction force of the vacuum nozzle 11 can reach its maximum, thus firmly adhering to the FPC and preventing movement. At the same time, in order to be suitable for FPCs of different specifications and strengths, the suction force of the vacuum nozzle 11 can be reduced by closing one or more of the first connecting pipes 6. This ensures that the FPC is firmly adhering while avoiding deformation or damage to the FPC due to excessive suction. This design ensures that the FPC remains relatively flat and stable during the inspection process, laying the foundation for high-quality imaging.
