[0032] The aging device 3 includes an aging base plate 34, an aging circuit board 31, an aging fixture 32, and a pressing structure 33; the aging base plate 34 is fixed on the frame 1; the aging fixture 32 is arranged on the aging circuit board 31, and the aging fixture 32 is provided with a number of station slots for placing the display; the aging circuit board 31 is arranged on the aging base plate 34 and can be electrically connected and communicatively connected to the display placed in the station slot, and is used for aging test and program burning of the display; the pressing structure 33 is connected to the aging base plate 34 and can fix the display in the station slot;

[0033] The vision recognition device 2 is communicatively connected to the controller 4 and is used for acquiring first image information of the area including the aging fixture 32 and the display and sending it to the controller 4;

[0034] The controller 4 is electrically connected to the aging circuit board 31 and is used for controlling the aging circuit board 31 to perform aging test and program burning on the display, and obtaining an aging test result according to the first image information.

[0035] For the automatic aging test and program burning device for a display proposed in this embodiment, by controlling the aging circuit board 31 to perform aging test and program burning on the display through the controller 4, the aging test and program burning can be automatically completed. The controller 4 can obtain the aging test result according to the first image information acquired by the vision recognition device 2, without manual operation and supervision, improving the efficiency, and moreover, it will not cause the aging test to fail to detect the quality defects of the display and the program selection error during program burning due to operator fatigue, and can improve the reliability of the aging test result and the efficiency of program burning.

[0036] In one embodiment, as Figure 2 shown, the pressing structure 33 includes a rotating mechanism 331 and a pressing plate 332. The rotating mechanism 331 is respectively connected to the aging base plate 34 and the pressing plate 332, and the rotating mechanism 331 can drive the pressing plate 332 to rotate relative to the aging base plate 34 to fix the display in the station slot.

[0037] In this embodiment, before the aging test, the pressing plate 332 has a certain angle with the aging base plate 34, which is convenient for placing the display into the aging fixture 32. The rotation mechanism 331 drives the pressing plate 332 to rotate relative to the aging base plate 34 to fix the display in the station slot, and then the aging test and program burning are performed on the display. After the aging test and program burning are completed, the rotation mechanism 331 can drive the pressing plate 332 to rotate back to its original position. Through the cooperation of the rotation mechanism 331 and the pressing plate 332, the placement and removal of the display can be carried out relatively quickly, improving the efficiency of the aging test and program burning.

[0038] In a further embodiment, as Figure 2 shown, the aging device 3 further includes a cylinder 35, a support plate 36, and a plurality of support columns 37;

[0039] Both ends of the plurality of support columns 37 are respectively connected to the support plate 36 and the aging circuit board 31;

The cylinder 35 can push the support plate 36 to move, and drive the aging circuit board 31 and the aging fixture 32 to move through the plurality of support columns 37, so as to clamp the display in the station slot between the aging fixture 32 and the pressing plate 332.

[0041] In this embodiment, when the pressing plate 332 rotates to fix the display in the station slot, in order to prevent the pressing plate 332 from directly pressing the display and causing damage to the display, there is still a distance between the pressing plate 332 and the display. The cylinder 35 can push the support plate 36 to drive the aging fixture 32 to move upward, so that the display in the station slot is clamped between the aging fixture 32 and the pressing plate 332 for aging and program burning. After completion, the cylinder 35 drives the support plate 36 to move downward. By using the support columns 37 to support the aging fixture 32, damage to the components on the display caused by the pressing of the pressing plate 332 can be avoided.

[0042] In a specific embodiment, as Figure 2 shown, the rotation mechanism 331 includes a first driving device 3311, a rack 3313, and a gear 3312;

[0043] The first driving device 3311 is fixedly connected to the aging base plate 34, and the first driving device 3311 is connected to the rack 3313; the first driving device 3311 can drive the rack 3313 to move linearly;

[0044] The gear 3312 is respectively connected to the pressing plate 332 and the aging bottom plate 34. The gear 3312 meshes with the rack 3313. The rack 3313 drives the gear 3312 to rotate, and the gear 3312 drives the pressing plate 332 to rotate together.

[0045] In this embodiment, the first driving device 3311 and the aging bottom plate 34 can be fixedly connected by bolts. Before placing the display in the aging fixture 32, the included angle between the pressing plate 332 and the aging bottom plate 34 is 90 degrees. After the working slots of the aging fixture 32 are filled with displays, the rotating mechanism 331 can drive the pressing plate 332 to rotate until the included angle between the pressing plate 332 and the aging bottom plate 34 is 0 degrees, fixing the display between the aging fixture 32 and the pressing plate 332 for aging test and program burning. After the aging test and program burning are completed, the rotating mechanism 331 drives the pressing plate 332 to rotate so that the included angle between the pressing plate 332 and the aging bottom plate 34 is 90 degrees. When taking out the display from the aging fixture 32 and placing the display in the aging fixture 32, there is no obstruction in the vertical direction, making it more convenient and fast to take and place the display, and improving the efficiency of aging test and program burning.

[0046] In one embodiment, as Figure 2 shown, a limit screw 3321 is provided at one end of the pressing plate 332 away from the gear 3312, and a limit post 341 is correspondingly provided on the aging bottom plate 34. The pressing plate 332 fixes the display in the working slot, and the limit screw cooperates with the limit post. By the cooperation of the limit screw and the limit post, the pressing plate 332 is limited to prevent the pressing plate 332 from rotating excessively and damaging the display, improving the reliability of the device.

[0047] In one embodiment, as Figure 2 shown, a notch 3322 is provided at one end of the pressing plate 332 close to the gear 3312. By providing the notch 3322, the material of the pressing plate 332 can be saved, reducing the manufacturing cost of the device.

[0048] In one embodiment, as Figure 2 shown, a plurality of through holes 3323 are provided on the surface of the pressing plate 332; the pressing plate 332 fixes the display in the working slot, and the plurality of through holes 3323 can expose part of the area of the display. By providing the plurality of through holes 3323, it is convenient for the visual recognition device 2 to obtain the first image information of the area including the aging fixture 32 and the display during the aging test to determine whether the display is lit, improving the accuracy and reliability of the aging test.

[0049] Embodiment 2

[0050] This embodiment proposes an automatic aging test and program burning system for a display. Refer toFigures 1-4 As shown in the figure, it includes a transfer device 5 and the automatic aging test and program burning device for the display described in the first embodiment.

[0051] The transfer device 5 is electrically connected to the controller 4.

[0052] The controller 4 is further configured to obtain the first position information of the vacant station slot according to the first image information, and control the transfer device 5 to transfer the display to the vacant station slot according to the first position information.

[0053] In this embodiment, as Figure 3 shown in the figure, the visual recognition device 2 may include a first camera 21 disposed on the frame 1, and the first image information of the area including the aging fixture 32 and the display is obtained through the first camera 21.

[0054] This embodiment provides an automatic aging test and program burning system for a display. The display is transferred to the vacant station slot through the transfer device 5, and the automation degree of the system is relatively high, which can improve the efficiency of the aging test and program burning.

[0055] In one embodiment, as Figure 3 shown in the figure, the transfer device 5 includes a robotic arm 51 and a picking and placing structure 52 connected to the robotic arm 51. The robotic arm 51 is disposed on the frame 1, and the robotic arm 51 can drive the picking and placing structure 52 to move; the picking and placing structure 52 transfers the display to the vacant station slot according to the first position information.

[0056] In this embodiment, the robotic arm 51 has multiple joints and high degrees of freedom, and can drive the picking and placing structure 52 to move freely in three-dimensional space. The picking and placing structure 52 can adopt a gripper or a suction cup. When using a suction cup, there is no need to reserve the space required for the gripper between adjacent displays, and the tray can be more compact. Therefore, in this embodiment, the picking and placing structure 52 preferably adopts a suction cup.

[0057] In a further embodiment, as Figure 3 and Figure 4 shown in the figure, the system further includes a display feeding device 6. The display feeding device 6 includes a tray rack 61, a first moving unit 62, an ejecting unit 63, a plurality of second moving units 64 and a plurality of trays 65, wherein:

[0058] The first moving unit 62 is connected to the frame 1 and the tray rack 61, and can drive the tray rack 61 to move in the vertical direction.

[0059] Specifically, the first moving unit 62 may include a first guide rail 621, a first slider 622, and a second driving device 623. The first guide rail 621 is vertically arranged on the frame 1. The first slider 622 is respectively connected to the second driving device 623 and the tray rack 61. The first slider 622 can slide along the first guide rail 621, and the second driving device 623 is used to drive the slider to slide.

[0060] The plurality of second moving units 64 are horizontally placed in the tray rack 61. Adjacent two of the second moving units 64 are arranged at a preset distance interval in the vertical direction. Each second moving unit 64 is connected to one tray 65, and the tray 65 can slide along the second moving unit 64.

[0061] Specifically, the second moving unit 64 may include a second guide rail 641 and a second slider 642. The second guide rail 641 is horizontally arranged on the tray rack 61. The second slider 642 is connected to the tray 65, and the second slider 642 can slide along the second guide rail 641.

[0062] The ejecting unit 63 can push the tray 65 on the same horizontal plane as the ejecting unit 63 to move. The tray 65 is provided with a plurality of placement slots for placing displays.

[0063] Specifically, the ejecting unit 63 may include an ejecting rod 631 and a third driving device 632. The third driving device 632 is fixed on the frame 1. The third driving device 632 is connected to the ejecting rod 631. The third driving device 632 can drive the ejecting rod 631 to perform a linear motion to push the tray 65 on the same horizontal plane as the ejecting rod 631 to move.

[0064] The visual recognition device 2 is also used to acquire second image information of the area including the tray 65 and send it to the controller 4.

[0065] Specifically, the visual recognition device 2 may further include a second camera 22 arranged on the tray rack 61. The second image information of the area including the tray 65 is acquired through the second camera 22.

[0066] The controller 4 obtains the second position information of the display in the placement slot according to the second image information, and controls the transfer device 5 to pick up the display from the placement slot according to the second position information.

[0067] In this embodiment, the second driving device 623 and the third driving device 632 adopt electric cylinders. An electric cylinder is a modular product that integrates a servo motor and a lead screw, converting the rotational motion of the servo motor into the linear motion of the lead screw. A plurality of trays are stacked vertically in the tray rack 61. The third driving device 632 drives the ejector rod 631 to perform a linear motion to eject the lowermost tray. After all the displays in the tray to be ejected are taken out by the transfer device 5, the third driving device 632 drives the ejector rod 631 to retract. The tray is retracted into the tray rack 61 under the action of the reset mechanism. The second driving device 623 drives the tray rack 61 to move downward by a preset distance. The third driving device 632 drives the ejector rod 631 to perform a linear motion to eject the second tray. Repeat the above steps to take out the displays in each tray one by one.

[0068] In a further embodiment, the display feeding device 6 further includes a reset mechanism (not shown in the figure) respectively connected to the tray rack 61 and the tray. The reset mechanism can drive the tray to reset when the ejector rod 631 retracts. By the reset mechanism driving the tray to automatically reset when the ejector rod 631 retracts, the tray after picking up the display does not occupy space, the structure is more compact, the occupied space is small, and the placement of the device is more flexible in a limited space.

[0069] In a specific embodiment, the reset mechanism adopts a rubber band. When the ejector rod 631 ejects the tray, the rubber band is stretched. When the ejector rod 631 retracts, the resilience of the rubber band drives the tray to reset into the tray rack 61. In this embodiment, a high-elastic rubber band is adopted.

[0070] In another specific embodiment, the reset mechanism adopts a spring. When the ejector rod 631 ejects the tray, the thrust of the ejector rod 631 causes the spring to stretch and deform. When the ejector rod 631 retracts, the thrust is eliminated, and the spring returns to its original state, thereby driving the tray to reset into the tray rack 61.

[0071] In the embodiment of the present invention, the controller adopts a PLC (Programmable Logic Controller, abbreviated as PLC, also known as a programmable logic controller). Signal interaction is carried out among the transfer device, the controller, and the visual recognition device to complete the action process. Communication between the transfer device and the controller is carried out through CC-Link, and the communication method between the visual recognition device and the controller is Enthernet. The controller plays a bridging role in the middle.

[0072] The working principle of this system is as follows:

[0073] Step 1: The controller 4 drives the second driving device 623 on the display feeding device 6 to move, so that the display feeding device 6 stops moving after the specified tray reaches the ejection position;

[0074] Step 2: The controller 4 drives the third driving device 632 to drive the ejector rod 631 to push out the target tray.

[0075] Step 3: The controller 4 feeds back a signal to the transfer device 5. The transfer device 5 moves above the tray. The first camera 21 is aligned with the first monitor to be grasped. The controller 4 feeds back a signal to the first camera 21 to trigger the first camera 21 to take a picture. After the picture taking is completed, the visual recognition device calculates the deviation value between the actual position of the monitor and the theoretical coordinates. The first camera 21 feeds back the deviation value to the controller 4, and the controller 4 then feeds back the deviation value to the transfer device 5. The transfer device 5 performs position compensation according to the deviation value and then grasps the first monitor.

[0076] Step 4: The transfer device 5 moves the monitor above the second camera 22. The controller 4 feeds back a signal to the visual recognition device to trigger the second camera 22 to take a picture. The visual recognition device calculates the deviation value between the center of the picking and placing structure 52 and the center of the monitor to be grasped. The visual recognition device feeds back the deviation value to the controller 4, and the controller 4 then feeds back the deviation value to the transfer device 5.

[0077] Step 5: The transfer device 5 then runs above the aging fixture 32. The first camera 21 is aligned with the station slot to be placed. The controller 4 feeds back a signal to the visual recognition device to trigger the first camera 21 to take a picture. The visual recognition device calculates the deviation value between the actual position of the station slot and the theoretical coordinates. The visual recognition device feeds back the deviation value to the controller 4, and the controller 4 then feeds back the deviation value to the transfer device 5.

[0078] Step 6: The transfer device 5 performs position compensation and correction according to the deviation value between the center of the picking and placing structure 52 and the center of the monitor to be grasped and the deviation value between the actual position of the station slot and the theoretical coordinates, and then accurately places the monitor to be grasped into the station slot.

[0079] Step 7: Steps 3 to 6 are a complete feeding action for one monitor. Then, this action continues to loop. There are a total of a aging fixtures 32 in a set of systems, and each aging fixture 32 has a total of b station slots, with a total of a×b station slots, until all the station slots of all the aging fixtures are filled with monitors.

[0080] Step 8: Next, the transfer device 5 feeds back a signal to the controller 4. The controller 4 drives the first driving device 3311 to move, driving the rack 3313 to move. The rack 3313 meshes with the gear 3312, driving the pressing plate 332 to close downward. The limit screw 3321 and the limit post 341 are pressed for limiting. To prevent damage to the display, there is still a distance between the pressing plate 332 and the display at this time. Then the controller 4 drives the cylinder 35 to push upward to drive the support plate 36, so that the pressing plate 332 is pressed against the display. The controller 4 gives a power supply control signal to conduct an aging test on the display. The aging time is 8 hours. After the aging is completed, the program is burned into the display until all the displays have completed the program burning.

[0081] Step 9: The controller 4 drives the first driving device 3311 to move, driving the rack 3313 to move. The rack 3313 meshes with the gear 3312, driving the pressing plate 332 to open upward.

[0082] Step 10: The controller 4 drives the second driving device 623 on the display feeding device 6 to move, so that the designated tray stops after reaching the pushing position. The controller 4 drives the third driving device 632 to push out the target tray.

[0083] Step 11: Then enter the material return link. The controller 4 sends a signal to the transfer device 5. The transfer device 5 runs above the BI position. The first camera 21 is aligned with the first display to be grabbed. The controller 4 sends a signal to the visual recognition device to trigger the first camera 21 to take a picture. The visual recognition device calculates the deviation value between the actual position of the display and the theoretical coordinates, and then feeds back the deviation value to the controller 4. The controller 4 then feeds back the deviation value to the transfer device 5. The transfer device 5 performs position correction according to the deviation value and then grabs the display.

[0084] Step 12: The transfer device 5 drives the display to run above the second camera 22. The second camera 22 is aligned with the display to be grabbed. The controller 4 sends a signal to the visual recognition device to trigger the second camera 22 to take a picture. The visual recognition device calculates the deviation value between the center of the picking and placing structure 52 and the center of the display to be grabbed. The visual recognition device feeds back the deviation value to the controller 4. The controller 4 then feeds back the deviation value to the transfer device 5.

[0085] Step 13: The transfer device 5 runs above the pushed-out tray. The first camera 21 is aligned with the working slot to be placed. The controller 4 sends a signal to the visual recognition device to trigger the first camera 21 to take a picture. The visual recognition device calculates the deviation value between the actual position of the working slot and the theoretical coordinates. The visual recognition device feeds back the deviation value to the controller 4. The controller 4 then feeds back the deviation value to the transfer device 5.

[0086] Step 14: The transfer device 5 performs position compensation and correction according to the deviation value between the center of the picking and placing structure 52 and the center of the display to be picked, and the deviation value between the actual position of the tray station slot and the theoretical coordinates, and then accurately places the display to be picked into the station slot.

[0087] Step 15: Repeat Steps 11 to 14 until all 576 displays with BI completed are placed back into the trays.

[0088] Through the above 15 steps, a complete workflow of the display automatic aging test and program burning system is completed. There are c trays placed in the display feeding device 6 in total, with d displays placed in each tray. There are 2 display feeding devices 6 on the left and right in total, and 2×c×d displays can be loaded at one time, which can supply the display aging work for 6 cycles.
