Description

Technical Field

[0001] This invention relates to the field of panel inspection technology, and in particular to a panel flow splitting inspection system. Background Technology

[0002] During panel manufacturing, panels need to undergo aging tests, lamp-lit tests, and other inspections to verify their performance and quality. Traditional online panel inspection systems mostly employ linear production lines, as shown in Chinese patents CN 215219355 U and CN 215219355 U. After material loading, inspection mechanisms are sequentially set up in series or parallel to complete the setup of multiple inspection lines. This type of inspection system typically discharges material uniformly at the exit point. Theoretically, it can inspect multiple groups of products simultaneously. However, in practical applications, each inspection line in the same group may be testing different modules simultaneously. Since the inspection speeds of different modules are usually different, the requirements for the coordination of inspection speeds and timing between the inspection lines are high. Even a slight time error in the inspection speed or timing of some inspection lines can cause blockages at the exit or return point. Summary of the Invention

[0003] The purpose of this invention is to provide a panel flow distribution detection system that supports at least two sets of online detections and is less prone to material blockage during the detection process.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: Furthermore, a panel sorting and testing system includes a sorting transfer platform, a return conveyor line, a discharge platform, at least two testing production lines, and a transfer device for transferring panels. The sorting transfer platform is used to place the panels to be tested. The transfer device is provided between the rear end of the return conveyor line and the discharge platform. One of the testing production lines is connected between the sorting transfer platform and the discharge platform, and the other testing production lines are connected to the discharge platform via the return conveyor line and the transfer device.

[0005] Furthermore, it also includes a feeding platform and a material distribution conveyor line, wherein the transfer device is provided between the front end of the material distribution conveyor line and the feeding platform, and between the rear end of the material distribution conveyor line and the material distribution transfer platform.

[0006] Furthermore, the testing line includes several aging furnaces and several external testing mechanisms. The external testing mechanisms are located at the front and / or rear of the aging furnaces to perform quality testing on panels that have not yet been sent into the aging furnaces and / or panels that have been sent out of the aging furnaces.

[0007] Furthermore, the external inspection mechanism includes a lighting inspection mechanism located at the front end of the aging furnace. A test board is inserted into the panel before it enters the aging furnace. The test board is used to light up the panel. A wire-pulling station is provided at the rear end of the aging furnace to separate the panel from the test board.

[0008] Furthermore, the testing line also includes a transfer mechanism for conveying the panel from the aging furnace to the wire pulling station. The test board includes a board body, a connecting cable, and an adapter. The connecting cable and the adapter are respectively fixedly connected to the board body. Magnetic metal sheets and elastic contacts are provided on both the front and back sides of the board body. Electromagnets and contact electrodes are provided on the transfer mechanism, the wire pulling station, and inside the aging furnace. The positions of the electromagnets and the magnetic metal sheets, and the positions of the contact electrodes and the elastic contacts, correspond one-to-one and can contact and connect with each other.

[0009] Furthermore, the testing line also includes a buffer platform for temporarily placing panels for panel transfer. The buffer platform includes multiple vertically arranged inverted L-shaped support rods. The support rods are arranged in two rows opposite or back to each other, and the two rows of support rods are spaced apart. The top surfaces of each support rod are located on the same horizontal plane to support the panel.

[0010] Furthermore, the caching platform is equipped with a CCD positioning device for locating the product position.

[0011] Furthermore, the return material conveyor line and the distribution material conveyor line are arranged parallel to each other and in opposite directions, and the conveying length of the distribution material conveyor line is shorter than that of the return material conveyor line.

[0012] Furthermore, maintenance corridors for maintenance personnel to pass through and perform maintenance are provided on the sides of the return material conveyor line and the distribution material conveyor line, and ladders are provided between the maintenance corridors and the ground.

[0013] Furthermore, both the return material conveying line and the distribution material conveying line include a linear slide rail, a fixed platform, a transfer assembly, a drive device, and a transfer platform. The fixed platforms are spaced apart along the sliding direction of the linear slide rail, and the transfer assembly is provided between any two adjacent fixed platforms. The transfer platform is located at both ends of the linear slide rail and is used to place the panel delivered by the transfer device. The transfer assembly is provided between the transfer platform and the fixed platform. The transfer assembly includes a transfer platform, a lifting device, and a base plate arranged sequentially from top to bottom. The base plate is slidably connected to the linear slide rail. The lifting device is used to drive the transfer platform to rise and fall. The shapes of the fixed platform and the transfer platform match the shape of the transfer platform and allow the transfer platform to rise and fall and slide along the linear slide rail. The drive device is used to drive the base plate to drive the transfer platform to slide back and forth along the linear slide rail between two fixed platforms or between a fixed platform and a transfer platform.

[0014] Furthermore, the transfer device includes a base and two transfer mechanisms. Each transfer mechanism includes a vertical slide rail, a horizontal slide rail, a sliding seat, and multiple horizontally arranged dental rods. The bottom of the vertical slide rail is fixedly connected to the base. The horizontal slide rail is slidably connected to the vertical slide rail. The sliding seat is slidably connected to the horizontal slide rail and fixedly connected to one end of each dental rod. The dental rods are spaced apart from each other and have flush top surfaces. The ends of each dental rod connected to the sliding seat are on the same side, and the end away from the sliding seat is a free end. The two transfer mechanisms are arranged opposite each other, and the sliding directions of the horizontal slide rails are parallel to each other. The dental rods on the two transfer mechanisms are staggered and avoid each other vertically, and the free ends face opposite directions.

[0015] The present invention has the following beneficial effects: 1. The system diverts materials through a material distribution and transfer platform, and can simultaneously inspect at least two sets of panels. Some panels are sent directly to the discharge platform after inspection, while others are returned to the discharge platform via a return conveyor line. By staggering the time when the panels are transported from each inspection line to the discharge platform, the system can buffer situations such as sudden increases in feeding speed or feeding amount at certain locations, making it less prone to material blockage.

[0016] 2. The return material conveyor and the distribution material conveyor are located at a high position, and maintenance corridors and ladders are set on their sides to facilitate personnel to handle any malfunctions or material blockages.

[0017] 3. The aging test process can be powered on throughout, facilitating real-time communication for full product monitoring, which helps reduce the occurrence of product failures. Attached Figure Description

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] like Figure 1-8 As shown, this invention discloses a panel 41 diversion detection system, including a material transfer platform 4, a return material conveyor line 5, a discharge platform 6, at least two detection production lines 8, and a transfer device 33 for transferring the panels 41. The material transfer platform 4 is used to place the panels 41 to be tested. The transfer device 33 is provided between the rear end of the return material conveyor line 5 and the discharge platform 6. One of the detection production lines 8 is connected between the material transfer platform 4 and the discharge platform 6, and the remaining detection production lines 8 are connected to the discharge platform 6 via the return material conveyor line 5 and the transfer device 33. The distance traveled by the panel 41 from the material transfer platform 4 through each detection production line 8 to the discharge platform 6 is of different lengths, so that the time taken for the panel 41 to reach the discharge platform 6 through each detection production line 8 is different, and the arrival times of the panels 41 can be staggered.

[0041] When there are multiple inspection lines 8, one of them can be directly set between the material transfer platform 4 and the discharge platform 6. The others can be connected to the discharge platform 6 through multiple return material conveyor lines 5 of different lengths, or through different positions at the front end of the return material conveyor line 5.

[0042] The system also includes a feeding platform 1 and a sorting conveyor line 3. Transfer devices 33 are installed between the front end of the sorting conveyor line 3 and the feeding platform 1, and between the rear end of the sorting conveyor line 3 and the sorting transfer platform 4. By setting up the sorting conveyor line 3, the panels 41 to be tested outside the system can be transported to the sorting transfer platform 4, preparing for sorting and testing. The feeding platform 1 and the discharging platform 6 can respectively use a feeding robot 2 and a sorting robot to pick up and discharge the panels 41.

[0043] The testing line 8 includes several aging furnaces 9 and several external testing mechanisms. These external testing mechanisms are located at the front and / or rear of the aging furnaces 9 to perform quality inspections on panels 41 that have not yet been sent into the aging furnaces 9 and / or on panels 41 that have been sent out of the aging furnaces 9. The external testing mechanisms can be selected according to actual testing needs to perform aging tests, lamp tests, surface defect inspections, and other testing items. Different equipment can be selected for the external testing mechanisms in different testing lines 8 to perform different types of tests simultaneously.

[0044] Taking one scenario as an example, the external testing mechanism includes a lighting testing mechanism 10 located at the front end of the aging furnace 9. A test board 18 is inserted into the panel 41 before it enters the aging furnace 9. The test board 18 is used to illuminate the panel 41. A wire-removal station 11 is provided at the rear end of the aging furnace 9 to separate the panel 41 from the test board 18. For example... Figure 10 As shown, the test board 18 used is a JIG board. The test board 18 includes a board body 19, a connecting cable 20, and an adapter 21. The connecting cable 20 and the adapter 21 are respectively fixedly connected to the board body 19. The testing line 8 also includes a transfer mechanism 15 for conveying the panel 41 from the aging furnace 9 to the wire pulling station 11.

[0045] At the front end of the aging furnace 9, that is, before entering the aging furnace 9, the panel 41 can be manually operated to perform operations such as inserting the test board 18 and lighting up for testing. After the panel 41 is sent out of the aging furnace 9 to the wire pulling station 11, the test board 18 connected to the panel 41 is pulled out. During this process, power supply and communication equipment can be set up inside the aging furnace 9 to monitor the aging test process in real time. However, in the stage after the panel 41 is sent out of the aging furnace 9 and before it is sent to the wire pulling station 11, power supply and communication are not possible. Some panels 41 may malfunction during this stage and cannot be monitored. To address this, magnetic metal sheets 22 and elastic contacts 24 are set on both sides of the panel 19. Electromagnets and contact electrodes are set on the transfer mechanism 15, the wire pulling station 11, and inside the aging furnace 9. The positions between the electromagnets and the magnetic metal sheets 22, and between the contact electrodes and the elastic contacts 24, correspond one-to-one and can contact and connect with each other.

[0046] The elastic contact 24 can be set on the silver-plated copper contact block, and the magnetic metal sheet 22 can be made of iron sheet in conjunction with an electromagnet to prevent the test board 18 from shifting, thus ensuring a stable connection between the elastic contact 24 and the contact electrode. Additionally, positioning structures, such as protrusions and grooves, can be correspondingly set between the test board 18 and the transfer mechanism 15, the wire pulling station 11, and the aging furnace 9 to ensure precise alignment. The panel 41, through the elastic contact 24 on the test board 18 to which it is inserted, can first connect to and be energized with the aging furnace 9 during the transfer from the aging furnace 9 to the wire pulling station 11, and then connect to and be energized with the transfer mechanism 15 when transferred to the transfer mechanism 15, and so on, achieving uninterrupted power supply throughout the process. Furthermore, a communication module can be inserted before the panel 41 is fed into the aging furnace 9 to enable continuous communication during this stage for real-time monitoring.

[0047] like Figure 9 As shown, the testing line 8 also includes a buffer platform 12 for temporarily placing panels 41 for transfer. The buffer platform 12 includes multiple vertically arranged inverted L-shaped support rods 13. Two rows of support rods 13 are arranged opposite or back-to-back, with each row spaced apart. The top surfaces of all support rods 13 are on the same horizontal plane to support the panels 41, facilitating the transfer of the panels 41. The buffer platform 12 can be located between the testing line 8 and the material transfer platform 4, the discharge platform 6, and the return material conveyor line 5, or between the external testing mechanism and the aging furnace 9. It can also serve as either the material transfer platform 4 or the discharge platform 6. The buffer platform 12 is equipped with a CCD positioning device 14 for locating the product position. The CCD positioning device 14, in conjunction with the transfer mechanism, can accurately place the panels 41 on the buffer platform 12, and can automatically correct the position according to different work orders. Figure 8 As shown, the aforementioned transfer mechanism includes a suction device 16 that picks up the transfer panel 41 between the wire pulling station 11 and the buffer platform 12, an ARM shaft that drives the suction device 16 to change position, and a transfer cart 17 that transfers the transfer panel 41 between the buffer platform 12 and the aging furnace 9. Both the suction device 16 and the transfer cart 17 are equipped with electromagnets and contact electrodes.

[0048] like Figure 11-17 As shown, the return material conveyor line 5 and the distribution material conveyor line 3 are arranged vertically parallel to each other and in opposite directions. The conveying length of the distribution material conveyor line 3 is shorter than that of the return material conveyor line 5. The vertical arrangement of the return material conveyor line 5 and the distribution material conveyor line 3 saves system floor space. With two detection lines 8, the length of the distribution material conveyor line 3 is approximately half that of the return material conveyor line 5.

[0049] The return material conveyor line 5 and the distribution material conveyor line 3 are provided with a maintenance corridor 31 on the side for maintenance personnel to pass through and perform maintenance. A ladder 32 is installed between the maintenance corridor 31 and the ground. Since the current panel 41 return method usually adopts bottom return or same-layer return, the position of the return line is relatively close to the ground. During maintenance, maintenance personnel need to crawl to the bottom of the return line to handle it, which is difficult to maintain and difficult to deal with blockage. However, by raising the return material conveyor line 5 and the distribution material conveyor line 3 to adopt the overhead return method and setting up the maintenance corridor 31 and ladder 32, maintenance is more convenient and blockage is easier to handle.

[0050] Both the return material conveyor line 5 and the distribution material conveyor line 3 include a linear slide rail, a fixed platform 25, a transfer assembly 26, a drive device, and a transfer platform 30. The fixed platforms 25 are spaced apart along the sliding direction of the linear slide rail, and a transfer assembly 26 is provided between any two adjacent fixed platforms 25. The transfer platform 30 is located at both ends of the linear slide rail and is used to place the panel 41 delivered by the transfer device 33. The transfer assembly 26 is provided between the transfer platform 30 and the fixed platform 25. The transfer assembly 26 includes components arranged sequentially from top to bottom. The transfer platform 27, lifting device 28, and base plate 29 are provided. The base plate 29 is slidably connected to the linear slide rail. The lifting device 28 is used to drive the transfer platform 27 to rise and fall. The shapes of the fixed platform 25 and the transfer platform 30 are matched with the shape of the transfer platform 27, and the transfer platform 27 can be lifted and passed through and slide along the linear slide rail. The drive device is used to drive the base plate 29 to drive the transfer platform 27 to slide back and forth along the linear slide rail between the two fixed platforms 25 or between the fixed platform 25 and the transfer platform 30.

[0051] The transfer platform 27 is fishbone shaped, the fixed platform 25 consists of two comb-shaped plates 19, and the structure of the transfer platform 30 is similar to that of the buffer platform 12, facilitating the transfer of the panel 41 via the transfer device 33. The panel 41 transferred by the transfer device 33 can be placed on top of the transfer platform 30. When the panel 41 is transported via the return conveyor line 5 and the distribution conveyor line 3, the transfer platform 27 first slides to the center of the bottom of the transfer platform 30, then rises and passes through the transfer platform 30. The panel 41 on the transfer platform 30 is lifted and transferred to the top of the transfer platform 27. Then, the transfer platform 27 carrying the panel 41 slides to the center of the adjacent fixed platform 25 and descends to lower the panel 41 to the top of the fixed platform 25, realizing the position change of the panel 41 from the transfer platform 30 to the fixed platform 25. Then, this process is repeated to transport the next panel 41. The same principle applies when the transfer platform 27 transports the panel 41 between the fixed platforms 25. By connecting multiple transfer segments in sequence, long-distance transport of panel 41 can be achieved, and multiple panel 41 products can be transported at the same time. The average transport time of a single panel is short, the transport speed is fast, and the products are less likely to be damaged by friction during transport.

[0052] like Figure 18-20 As shown, the transfer device 33 includes a base 34 and two transfer mechanisms 35. Each transfer mechanism 35 includes a vertical slide rail 36, a horizontal slide rail 37, a sliding seat 38, and multiple horizontally arranged insert rods 39. The base 34 is fixedly connected to the bottom of the vertical slide rail 36. The horizontal slide rail 37 is slidably connected to the vertical slide rail 36. The sliding seat 38 is slidably connected to the horizontal slide rail 37 and fixedly connected to one end of each insert rod 39. The insert rods 39 are spaced apart and have flush top surfaces. The ends of each insert rod 39 connected to the sliding seat 38 are on the same side, and the end furthest from the sliding seat 38 is a free end 40. The two transfer mechanisms 35 are arranged opposite each other, and the sliding directions of the horizontal slide rails 37 are parallel. The insert rods 39 on the two transfer mechanisms 35 are staggered and avoid each other vertically, with their free ends 40 facing opposite directions. The horizontal slide rail 37 is a multiplier rail.

[0053] Corresponding to the sky return flow, the vertical slide rails 36 of the two transfer mechanisms 35 have different travel lengths. Taking the transfer of panel 41 between the feeding platform 1 and the distribution conveyor line 3 as an example, the transfer mechanism 35 with the shorter vertical slide rail 36 travel is the first transfer mechanism 35, and the transfer mechanism 35 with the longer vertical slide rail 36 travel is the second transfer mechanism 35. When transferring panel 41, panel 41 is taken out from the buffer platform 12 by the first transfer mechanism 35 through the toothed insert. After the panel 41 is taken out and slid, the toothed insert rod 39 of the first transfer mechanism 35 is exactly above the toothed insert rod 39 of the second transfer mechanism 35. The second transfer mechanism 35 is driven to make its toothed insert rod 39 pass upward to transfer panel 41 onto the toothed insert rod 39 of the second transfer mechanism 35, and then the panel 41 is transferred to the transfer platform 30. Through this transfer device 33, panel 41 can be transferred between two positions with different heights on both sides, and the transfer is smooth and fast.

[0054] In this system, the structure on top of the feeding platform 1, the discharging platform 6, the transfer platform 30, and the distribution transfer platform 4 that supports the product is similar to that of the buffer platform 12, which facilitates the transfer of the toothed insert. Therefore, some of the buffer platforms 12 can also serve as the distribution transfer platform 4 or the discharging platform 6, and can be transferred through the transfer component 26.

[0055] Preferably, the system is equipped with two detection lines 8 arranged in a straight line on both sides of the material distribution and transfer platform 4. One line is directly connected to the discharge platform 6, and the other line is connected to the discharge platform 6 through the return material conveyor line 5. Both detection lines 8 are equipped with a light-up detection mechanism 10. When the panel 41 is subjected to online aging test using this system, the panel 41 fed into the system is first picked up by the feeding robot 2 and placed on the feeding platform 1. It is then transferred to the front end of the material distribution conveyor line 3 by the transfer device 33. After the panel 41 is transported to the rear end of the material distribution conveyor line 3, it is transferred to the material distribution transfer platform 4 by the transfer device 33. The panel 41 to be tested sent to the material distribution transfer platform 4 is diverted to the two side detection lines 8. After the test board 18 is inserted and the light test is performed, it is sent into the aging furnace 9 for aging test. Then, it is sent out of the buffer platform 12 by the transfer car 17, and then sent to the wire pulling station 11 by the ARM axis and the suction device 16 to remove the test board 18. After that, it is sent to the discharge platform 6 and picked up by the discharge robot 7.

[0056] When performing online testing through this system, the time intervals between the test panels 41 of each testing line 8 being sent to the discharge platform 6 are staggered, so even if there is a sudden increase in the feeding speed or the amount of feeding, it is not easy for material blockage to occur.

The dental rods on the two transfer mechanisms are staggered and avoid each other vertically, and their free ends face opposite directions.
