Description

Technical Field

[0001] The present invention relates to the technical field of FPCA processing, and more specifically, it relates to an integrated machine for automatic testing and packaging of FPCAs. Background Art

[0002] FPCA is an assembly technology for flexible printed circuit boards. Compared with traditional hardware circuit boards, FPCAs have the advantages of being lighter, thinner, and more flexible. They can provide a certain degree of flexibility and can be used in occasions where bending or folding is required, making them widely used in fields such as mobile electronic devices, medical devices, automotive electronics, and wearable devices.

[0003] Currently, the testing and packaging of FPCAs are mostly carried out on two or more devices, resulting in poor production and processing continuity. Therefore, in the prior art, there has emerged an integrated device for automatic testing and packaging of FPCAs to improve the continuity and consistency of FPCA processing to a certain extent.

[0004] When the existing integrated device tests and packages FPCAs, it usually transfers the circuit boards through a suction cup manipulator. First, the circuit board is adsorbed from the tray and transferred to the detection table. After detection, it is adsorbed and transferred to the packaging table for packaging. Since FPCAs are divided into single-layer flexible circuit boards and multi-layer flexible circuit boards, the multi-layer flexible circuit boards are mostly connected to the substrates and circuit layers of each circuit board by adhesion or welding. And since independent interfaces are provided at the edge positions of each layer of the circuit board, and the interfaces are not welded to the adjacent layer of the circuit board, this will cause the interface protrusions of the lower-layer circuit board to easily squeeze and deform the substrate material of the upper-layer circuit board during the packaging, pressing, and film laminating operations of the multi-layer stacked flexible circuit boards, affecting the final processed product quality of the FPCA.

[0019] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the present specification. Various examples may omit, replace, or add various processes or components as needed. In addition, the features described in some examples may also be combined in other examples.

[0020] The present invention provides an integrated machine for automatic testing and packaging of FPCAs, as Figure 1 , Figure 2 and Figure 3 shown, which includes a frame 1. A detection probe 11 is arranged at the top of the frame 1. A vision camera is integrated in the detection probe 11. Through camera photographing, vision algorithms are used to detect defects, foreign objects, offsets, etc. on the surface of the circuit board. A transfer part is arranged on the surface of the frame 1. The transfer part includes a sliding plate 2 that slides on the surface of the frame 1. A plurality of connecting blocks 21 are installed on the surface of the sliding plate 2. A transfer arm 211 is slidably connected to the surface of the connecting block 21. The number of connecting blocks 21 determines the number of transfer arms 211 for transferring flexible circuit boards. The connecting block 21 is connected to the transfer arm 211 through a cylinder 212. The fixed end of the cylinder 212 is fixedly connected to the connecting block 21, and the output end of the cylinder 212 is fixedly connected to the transfer arm 211. When the cylinder 212 extends or contracts, the transfer arm 211 moves up and down along the surface of the connecting block 21. A transfer rack 22 is fixedly connected to the bottom of the transfer arm 211. A plurality of transfer rods 221 are installed on the surface of the transfer rack 22. A suction cup 222 for sucking the circuit board is arranged at the bottom of the transfer rod 221. The top of the transfer rod 221 is used to be connected to an external air source device, so as to facilitate the suction cup 222 to generate negative pressure to attract the circuit board. A regulating plate 23 is fixedly connected to one side of the transfer rack 22.

[0021] Specifically, through the setting of the transfer part, it is used to transfer flexible circuit boards at different positions. The transfer method is that the suction cup 222 contacts the surface of the flexible circuit board, and the air inside the suction cup 222 is sucked out to form negative pressure, so as to adsorb the flexible circuit board on the surface of the suction cup 222, thereby extracting the flexible circuit board. Then, through the contraction of the cylinder 212, the transfer arm 211 is lifted upward, so as to lift the flexible circuit board, and the transfer of the circuit board is carried out through the lateral movement of the sliding plate 2 on the surface of the frame 1.

[0022] As Figure 3 , Figure 4 and Figure 5As shown, in this embodiment, the packaging table 4 is arranged on one side at the bottom of the frame 1. A film placing tray 41 for holding the FPCA film is arranged on the top of the packaging table 4. The film placing tray 41 is used to place the packaging film for packaging the circuit board after cutting. Among them, the packaging film can also be adsorbed and transported by the suction cup 222 and pressed against the surface of the circuit board. A packaging groove is formed on the surface of the packaging table 4 near the film placing tray 41. Two sides of the inner wall of the packaging groove are hinged with a receiving plate 43. A number of air holes are formed on the surface of the receiving plate 43. An air cavity is formed inside the receiving plate 43. The air cavity is communicated with a number of air holes and is connected with an external air source device to provide a stable air output. A push plate 432 adapted to the adjusting plate 23 is slidably connected inside the packaging table 4. The push plate 432 is connected with the receiving plate 43 through a hinge plate 431. The hinge plate 431 is hinged on one side of the receiving plate 43, and the side of the hinge plate 431 away from the receiving plate 43 is slidably connected to the surface of the push plate 432. The push plate 432 is connected with the packaging table 4 through a spring 433. Two ends of the spring 433 are respectively fixedly connected with the push plate 432 and the packaging table 4. When the spring 433 is in a relaxed state, the receiving plate 43 is in a crossed state with the top plane of the packaging table 4.

[0023] Specifically, by pressing down the push plate 432, the spring 433 can be compressed, and at the same time, the hinge plate 431 is driven to move downward. Further, the receiving plate 43 is driven to rotate until the receiving plate 43 rotates to be parallel or coincident with the top plane of the packaging table 4. And since the receiving plate 43 is arranged at the two side edges of the packaging groove, the receiving plate 43 can be used to receive the two side edges of the circuit board, that is, the circuit board edge interface position. When laminating a multi-layer circuit board, the circuit board interface on the surface of the edge receiving plate 43 can be lifted upward by the air flow blown out through the air holes to fit with the packaging film. Compared with physical pressing, the air flow applies a softer force to the circuit board edge interface, which can effectively avoid the problem that the interfaces of the multi-layer circuit board cause extrusion damage to the adjacent layer substrate or circuit layer due to physical pressure.

[0024] As Figure 4 shown, in a further embodiment, a pressing component is further included and is arranged in the packaging groove. The pressing component includes a number of placing rails 44 fixedly connected to the inner wall of the packaging groove. The placing rails 44 are used to support the position near the center of the multi-layer circuit board. A sliding rod 441 is slidably connected to the surface of the placing rail 44. A roller 442 for contacting the bottom of the circuit board is rotatably connected to the top of the sliding rod 441. A driving component for driving the sliding rod 441 to reciprocate on the surface of the placing rail 44 is further included.

[0025] Specifically, compared with the edge position of the circuit board, the middle section of the circuit board is mostly composed of a base layer and a circuit layer, and there is no or less hard interface composition. Therefore, at this position, the roller 442 can roll at the bottom of the multi-layer circuit board to facilitate the tight fitting of the circuit board and the packaging film covering the top. Among them, the surface of the roller 442 is set as a soft anti-static rubber cylinder or other soft materials with anti-static effects to avoid damaging the multi-layer circuit board.

[0026] As Figure 4 , Figure 5 and Figure 6 shown, in this embodiment, a pressing block 242 is slidably connected to the surface of the adjusting plate 23. The pressing block 242 is connected to the adjusting plate 23 through a tension spring 243. Both ends of the tension spring 243 are fixedly connected to the pressing block 242 and the adjusting plate 23 respectively. When the tension spring 243 is in a relaxed state, the bottom of the pressing block 242 and the bottom of the adjusting plate 23 are on the same horizontal line. A synchronous plate 241 is slidably connected inside the transfer rack 22. The synchronous plate 241 slides up and down inside the transfer rack 22. A plurality of tooth grooves are formed on the surfaces of both the pressing block 242 and the synchronous plate 241. A connecting rod 24 is fixedly connected to the top of the synchronous plate 241. A transfer rod 221 is slidably connected inside the transfer rack 22, and a slider 246 is hinged to the surface of the transfer rod 221. The hinge shaft of the slider 246 and the transfer rod 221 slides inside the transfer rack 22, and the slider 246 is slidably connected inside the transfer rack 22. The slider 246 is connected to the connecting rod 24 through a pull rod 245. One end of the pull rod 245 is hinged to the surface of the slider 246, and the other end is hinged to the surface of the connecting rod 24. Among them, the connecting rod 24 is arranged at the center position of the transfer rack 22, and the transfer rods 221 are evenly distributed on both sides of it with the connecting rod 24 as the central axis. The sliding direction of the transfer rod 221 is towards or away from the connecting rod 24. A plurality of stoppers 247 adapted to the transfer rods 221 are fixedly connected to the inner bottom of the transfer rack 22. A synchronous rod 244 is rotatably connected inside the transfer rack 22. Gears are fixedly connected to both ends of the synchronous rod 244 and are respectively engaged with the pressing block 242 and the synchronous plate 241. A push block 434 adapted to the pressing block 242 is fixedly connected to one side of the push plate 432, and the height of the push block 434 is higher than that of the push plate 432. Support plates 438 are hinged to both sides of the inner wall of the packaging groove, and the support plates 438 are located at the bottom of the receiving plate 43.

[0027] Specifically, by setting the push block 434, when the suction cup 222 absorbs a plurality of multi-layer circuit boards to the top of the packaging slot and moves down to place the circuit boards, the pressing block 242 on one side of the transfer rack 22 first contacts the pushing block 434, and in the process of the transfer rack 22 continuously moving down, the pushing block 434 pushes the pressing block 242 and stretches the tension spring 243. In this process, the upward movement of the pressing block 242 causes the gear meshing with it to rotate, thereby driving the synchronization rod 244 to rotate, and the synchronization plate 243 on one side of the synchronization rod 244 is moved. Due to the meshing action, the connecting rod 24 is synchronously moved upward and pulls up the pull rods 245 on both sides thereof. The upward movement of the pull rods 245 synchronously pulls the two sliders 246 located on both sides of the connecting rod 24 to slide toward the connecting rod 24, and makes the two opposite transfer rods 221 located on both sides of the connecting rod 24 approach each other. Due to the blocking of the stopper 247, the transfer rods 221 are relatively tilted. At this time, the multi-layer circuit board adsorbed by the suction cup 222 will be in a state where the edges of both ends are upturned and the center is convex, as shown in FIG. Figure 5 In the state shown, in this state, the interfaces at both ends of the topmost circuit board will bend up with the transfer rod 221, while the interfaces at both ends of the circuit board near the lower layer will bend down accordingly. Through the inclination of the transfer rod 221, it is convenient to separate the interfaces between the layers of the multi-layer circuit boards from each other, and then make the interfaces near the bottom easier to stagger with the receiving plate 43, and only the topmost interface is placed on the surface of the receiving plate 43, and the receiving plate 43 is set to be tilted upward to reduce its lateral width on the horizontal plane, so as to facilitate the separation of the topmost circuit board interface from the adjacent layer interface. After separating the top circuit board interface from other layers, the deformation or damage caused by the mutual squeezing of the hard interfaces of the adjacent layers of circuit boards can be reduced during lamination. Therefore, the circuit board interface near the bottom is in a freely hanging suspended state during lamination, which does not affect the lamination operation on the surface of the top circuit board. Furthermore, through the setting of the support plate 438, it is used to receive the suspended circuit board interface near the bottom.

[0028] like Figure 6 , Figure 7 and Figure 8 As shown, further, in this embodiment, the push plate 432 and the top of the push block 434 are not on the same horizontal line, the push block 434 is higher than the push plate 432, and a plurality of pressure-sensitive buttons 435 are arranged on the top of the push plate 432. A card slot is opened in the packaging table 4, and a card block 437 is slidably connected to the card slot. The card block 437 is made of magnetic material, and an electromagnet 436 is installed on the inner wall of the card slot. The electromagnet 436 is electrically connected to the pressure-sensitive button 435.

[0029] Specifically, through the setting of the push block 434 whose height is higher than that of the push plate 432, in the initial state, the clamping block 437 is stuck at the bottom of the push plate 432, and the magnetic field of the electromagnet 436 generates a repulsive force on the clamping block 437. Therefore, when the pressing block 242 contacts the top of the push block 434, the push block 434 cannot move downward due to the blockage of the clamping block 437 at the bottom, so it will push the pressing block 242 upward relatively, lift the pressing block 242 upward, and then tilt the transfer rod 221, synchronously causing the interfaces at both ends of the adsorbed circuit board to tilt upward. Since there is a height difference between the push block 434 and the push plate 432, when the pressing block 242 is pushed upward, the adjusting plate 23 will not contact the pressure-sensitive button 435 on the surface of the push plate 432 for the time being. Therefore, at this time, the receiving plate 43 is still in an upward-tilted state, which is convenient for separating the interfaces of multiple layers. After the pressing block 242 rises to a certain height, the adjusting plate 23 can contact the pressure-sensitive button 435 on the surface of the push plate 432, thereby triggering the pressure-sensitive button 435. The pressure-sensitive button 435 transmits a signal to the electromagnet 436, and the electromagnet 436 changes the magnetic field direction, thereby sucking the clamping block 437 into the card slot, canceling the blockage of the push plate 432. At this time, the continuously descending adjusting plate 23 can push the push plate 432 and the push block 434 downward. The downward pressure of the push plate 432 will compress the spring 433, and then drive the hinge plate 431 to move downward to receive the plate 43, causing the receiving plate 43 to gradually rotate towards the horizontal direction. At this time, the circuit board is placed on the surface of the storage rail 44, and at this time, the suction cup 222 cancels the adsorption state of the circuit board.

[0030] Furthermore, the surface of the adjusting plate 23 is provided with a groove adapted to the clamping block 437. When the clamping block 437 pops out of the card slot, due to the setting of the groove, the clamping block 437 will not conflict with the adjusting plate 23.

[0031] Specifically, the pressure-sensitive button 435 can sense the contact or departure of the adjusting plate 23, thereby causing the electromagnetic solenoid 436 to switch the magnetic field direction, enabling the latch 437 to extend or retract from the card slot. In addition, a pressure limit can be set for the pressure-sensitive button 435. After reaching this limit, the electromagnetic solenoid 436 can also switch the magnetic field direction. Specifically, when the pressure-sensitive button 435 senses the contact state, the electromagnetic field direction is the direction that generates an attractive force on the latch 437, while when the pressure-sensitive button 435 senses departure or reaches the pressure limit, the electromagnetic field direction is the direction that generates a repulsive force on the latch 437. The specific implementation method is as follows: During the process of the adjusting plate 23 contacting and continuously pressing down the push plate 432, since the spring 433 is continuously compressed, its elastic potential energy gradually increases, so the thrust on the push plate 432 also gradually increases. Correspondingly, the pressure of the adjusting plate 23 on the pressure-sensitive button 435 will also gradually increase. After the pressure reaches the limit, the electromagnetic solenoid 436 changes the magnetic field direction, thereby pushing the latch 437 outwards. Since the push plate 432 is pressed down at this time, the latch 437 will block the top return position of the push plate 432. In this way, when the adjusting plate 23 moves up with the transfer rack 22 and cancels the contact with the pressure-sensitive button 435, the electromagnetic solenoid 436 still maintains the state of pushing the latch 437 out, and the push plate 432 still will not move up. At this time, the receiving plate 43 will still be in a horizontal position, facilitating the laying flat of the circuit board. When the suction cup 222 adsorbs the packaging film from the film placing disc 41 and covers and adheres it to the surface of the circuit board, the adjusting plate 23 continues to contact the pressure-sensitive button 435 on the surface of the push plate 432. At this time, the electromagnetic solenoid 436 generates an attractive force on the latch 437, retracting the latch 437 into the card slot. After the film covering is completed, the adjusting plate 23 moves up. At this time, due to the lack of obstruction by the latch 437, the push plate 432 can also return to the initial position under the elastic force of the spring 433.

[0032] It should be noted that during film covering, since the downward movement step of the transfer rack 22 is the same as the step of transferring the circuit board, the pressing block 242 will still be obstructed by the pushing block 434 during the downward movement, causing the pressing block 242 to move up, further tilting the transfer rod 221, making the packaging film also in an arc shape with both sides upturned and the center sunken. At this time, the central part of the packaging film first contacts the circuit board and first adheres tightly to the circuit board. At this time, the sliding rod 441 drives the roller 442 to roll under the circuit board, fitting the central position of the circuit board and the packaging film. Subsequently, both sides of the packaging film gradually contact the surface of the circuit board, and the two ends of the circuit board are adhered to the packaging film by the method of air blowing upwards. By gradually covering and adhering from the center to both sides, the air inside the film can be effectively discharged, achieving a more ideal packaging film covering and adhering effect.

[0033] Such as Figure 3As shown in the figure, in this embodiment, two fixed rails 42 are fixedly connected to the bottom inside the packaging groove. A number of rotating shafts are rotatably connected between the two fixed rails 42, and a packaging belt 421 is drivingly connected through the number of rotating shafts. A motor C422 is installed on one side of the fixed rail 42, and the output shaft of the motor C422 is axially fixedly connected to one of the rotating shafts. Through the output of the motor C422, the rotating shaft is driven to rotate, and then the entire packaging belt 421 is driven.

[0034] Furthermore, as Figure 7 and Figure 9 shown, in this embodiment, a feeding component is further included for moving the circuit board on the surface of the placing rail 44 out. The feeding component includes a discharging rod 443 hinged to one side of the sliding rod 441. A convex block 444 is fixedly connected to one side of the sliding rod 441. The convex block 444 is a rubber block. A number of packaging trays 423 for placing circuit boards are arranged on the surface of the packaging belt 421. The packaging trays 423 can move along with the driving of the packaging belt 421. The circuit board after film covering can be placed on the surface of the packaging tray 423 and sent to the subsequent packaging steps. An inclined plate adapted to the packaging tray 423 is arranged on one side of the placing rail 44, and the inclined plate is used to guide the circuit board into the packaging tray 423.

[0035] Specifically, through the setting of the discharging rod 443, in the normal state, its height does not exceed the top of the roller 442, so it will not obstruct the circuit board when the roller 442 rolls. When the sliding rod 441 runs to the end along the placing rail 44, that is, after the roller 442 finishes packaging, covering, and pressing a number of circuit boards, the discharging rod 443 contacts the inner wall of the packaging groove, and during the continuous running of the sliding rod 441, it is forced to rotate upward by the reaction force of the inner wall of the packaging groove until it crosses the convex block 444. Since the convex block 444 is a soft rubber block, it can act as a positioning function. After the discharging rod 443 rotates upward and crosses the convex block 444, the height of the discharging rod 443 is greater than that of the roller 442 at this time. At this time, the sliding rod 441 slides reversely on the surface of the placing rail 44. During this process, the discharging rod 443 pushes a number of circuit boards after film covering on the surface of the placing rail 44 forward until the circuit boards all slide down from the inclined plate and enter the packaging tray 423 for collection.

[0036] Furthermore, a returning rod 445 adapted to the discharging rod 443 is fixedly connected to the surface of the inclined plate. After the discharging rod 443 follows the sliding rod 441 to move to the position of the returning rod 445, it is pushed forward by the returning rod 445 again, crosses the convex block 444, and then returns to the original position, waiting for the next use.

[0037] As Figure 4 and Figure 6As shown in the figure, in this embodiment, the driving component includes a motor D446 fixedly connected to one side of the packaging table 4. Two driven wheels 447 are rotatably connected to the inner wall of the packaging table 4. A driving belt 448 is connected between the two driven wheels 447. The output shaft of the motor D446 is axially fixedly connected to one of the driven wheels 447. The motor D446 is a servo motor. Through the output of the motor D446, one of the driven wheels 447 is driven to rotate, and then the driving belt 448 is driven, so that the driving belt 448 drives the sliding rod 441 to slide on the surface of the placing rail 44.

[0038] It also includes a detection table 3 arranged at the inner bottom of the frame 1. A detection disk 31 adapted to the detection probe 11 is installed on the top of the detection table 3. Before packaging, the circuit board is transported to the surface of the detection disk 31, and the circuit board is detected by the detection probe 11. Two transfer rails 32 are fixedly connected to the inner bottom of the frame 1 near one side of the detection table 3. A number of movable shafts are rotatably connected between the two transfer rails 32, and a transfer belt 321 is connected through the number of movable shafts. A motor B322 is fixedly connected to one side of the transfer rail 32. The output shaft of the motor B322 is axially fixedly connected to one of the movable shafts. A number of transfer disks 323 are arranged on the surface of the transfer belt 321. The transfer disks 323 are used to place the circuit boards waiting for detection and packaging with film. Through the output of the motor B322, one of the movable shafts is driven to rotate, and then the transfer belt 321 is driven, so that the transfer disks 323 on the surface of the transfer belt 321 move, and the number of transfer disks 323 and the circuit boards on their surfaces are continuously moved to the position to be transferred.

[0039] A motor A12 is fixedly connected to one side of the frame 1. The output end of the motor A12 is fixedly connected to a screw rod 13. The screw rod 13 penetrates through both sides of the frame 1 and is threadedly connected to the sliding plate 2. Through the output of the motor A12, the screw rod 13 is driven to rotate, and then the sliding plate 2 can reciprocate on the surface of the frame 1.

[0040] Specifically, a number of groups of connecting blocks 21 are arranged on the surface of the sliding plate 2. Two groups are selected here. Through the transfer arms 211 on the two groups of connecting blocks 21, the circuit boards in two different links can be transferred at the same time. For example, the circuit boards on the transfer disk 323 and the surface of the detection disk 31 can be sucked at the same time, and the circuit board on the surface of the transfer disk 323 is transferred to the surface of the detection disk 31, while the other group of transfer arms 211 transfers the circuit board on the surface of the detection disk 31 to the position on the surface of the packaging table 4, improving the operation efficiency.

The above specific implementation manners are only illustrative and not restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make more equivalent embodiments in various forms, all of which fall within the protection scope of this embodiment.
