Referring to fig. 3a, the system for detecting a display panel further includes an image obtaining device 400, configured to obtain an image of the display panel to be detected on the feeding moving unit 320 when the feeding moving unit 320 moves to the image obtaining position, where a position corresponding to the second end B of the feeding linear guide 310 is multiplexed as the image obtaining position.
Specifically, the image capturing device 400 may be, for example, an industrial camera, and is used to position the feeding moving unit 320, and when the feeding moving unit 320 moves to the image capturing position, that is, the second end B of the feeding linear guide 310, the image capturing device 400 captures an image of the display panel to be tested at the second end B of the feeding linear guide 310.

Moreover, the second end B of the feeding linear guide 310 is the feeding grabbing position a1 of the feeding device 100, so that the image acquiring device 400 can acquire an image of the feeding device 100 grabbing the display panel to be tested, and when the grabbing position of the feeding device 100 does not accord with the preset position, the grabbing position of the feeding device 100 is adjusted in time, so that the feeding device 100 can safely grab the display panel to be tested.
Referring to fig. 3a and 3b, the detection system of the display panel further includes a blanking linear module 500, the blanking linear module 500 includes a blanking linear guide rail 510, a blanking moving unit 520, and a blanking grabbing mechanism 530, the blanking grabbing mechanism 530 is rotatably connected to the blanking moving unit 520, and the blanking moving unit 520 is configured to drive the blanking grabbing mechanism 530 to make a linear motion along the blanking linear guide rail 510; the blanking grabbing mechanism 530 is used for moving the blanking moving unit 520 to a position corresponding to the blanking station 230, grabbing the display panel of which the performance detection to be detected is finished at the blanking station 230, and rotating 90 degrees anticlockwise; the blanking grabbing mechanism 530 is further used for moving the blanking moving unit 520 to the second end D of the blanking linear guide rail 510, rotating 90 ° clockwise, and placing the display panel which completes the performance detection to be detected on the blanking transfer platform 540.
Specifically, the display panel's detecting system utilizes unloading straight line module 500 to carry out the unloading to the display panel after detecting, detect and remove to unloading station 230 after the completion when display panel, unloading snatchs mechanism 530 and snatchs the display panel after detecting from unloading station 230, snatch back unloading and snatch mechanism 530 anticlockwise rotation 90, make unloading snatch mechanism 530 and unloading linear guide 510 parallel, unloading motion unit 520 drives the unloading and snatchs mechanism 530 and make linear motion along unloading linear guide 510, snatch mechanism 530 with the unloading and remove to the second end D of unloading linear guide 510 from the first end C of unloading linear guide 510, unloading snatchs mechanism 530 clockwise rotation 90, place the display panel who will accomplish the performance detection that awaits measuring on unloading relay platform 540, thereby accomplish the unloading. It should be noted that the blanking grabbing mechanism 530 can obtain the display panels of a plurality of detection devices 200, and fig. 3a and 3b only show the grabbing of the display panels of two detection devices 200. The blanking grabbing mechanism 530 is used for grabbing blanking for display panels of different detection devices 200, so that blanking can be performed while feeding is performed, and time is saved. However, in the prior art, the same device is used for feeding and discharging, feeding and discharging of the same detection device 200 cannot be performed simultaneously, and referring to fig. 1, when the double-claw manipulator 820a is used for feeding the first detection device 710a, discharging of the first detection device 710a cannot be performed, and discharging of the first detection device 710a needs to depend on the second double-claw manipulator 820b, specifically, the first double-claw manipulator 820a grasps a display panel which is detected from a discharging station of the first detection device 710a and needs to be placed on the second movement unit 850, and then the second double-claw manipulator 820b grasps the display panel which is detected from the first detection device 710a from the second movement unit 850 and places the display panel on the discharging transfer platform, so that discharging can be achieved. That is, in the blanking process of the first detecting device 710a, the second detecting device 710b cannot realize the feeding and the blanking. Therefore, compared with the prior art, the technical scheme of the embodiment solves the interference problem in feeding and discharging, and saves time.
Referring to fig. 3a, the height of the discharging grabbing mechanism 530 is higher than the feeding moving unit 320 by a first preset distance.
Specifically, the height of the discharging grabbing mechanism 530 is higher than the first preset distance of the feeding moving unit 320, and illustratively, the first preset distance can be 35 mm, so that when the feeding linear module 300 is used for feeding, the discharging grabbing mechanism 530 can simultaneously carry out discharging, the interference problem of feeding and discharging is avoided, time is saved, and the detection efficiency is improved.
Alternatively, referring to fig. 3a, the interval L1 between the feeding device 100 and the first inspection device 200a may be 40 mm, and the interval L2 between the feeding device 100 and the second inspection device 200b may be 40 mm, so that the feeding device 100 has enough space to rotate and feed when feeding two adjacent inspection devices 200, thereby avoiding the problem that the second double-claw robot 820b can not grab the display panel to be tested from the second moving unit 850 and place the display panel to be tested on the second inspection device 710b until the first double-claw robot 820a grabs the display panel to be tested from the first moving unit 840 to the second moving unit 850 in the prior art. The problem of among the prior art different detection device correspond loading attachment have mutual interference at the material loading in-process is solved.
Referring to fig. 3a, the discharging linear guide 510 and the feeding linear guide 310 are separated by a second preset distance L3, and are located on a side of the feeding linear guide 310 away from the detecting device 200.
Illustratively, the blanking linear guide 510 is parallel to the feeding linear guide 310 and is located on a side of the feeding linear guide 310 away from the detection device 200, so as to avoid interference between feeding and blanking. The blanking linear guide rail 510 and the feeding linear guide rail 310 are separated by a second preset distance L3, optionally, the second preset distance L3 may be 40 mm, or may be other values, as long as the requirement that the feeding linear guide rail 310 and the blanking linear guide rail 510 do not interfere with each other during movement is met.
