实际生产中，本发明所述导光板面检治具装置的工作流程如下：In actual production, the working process of the light guide plate surface inspection fixture device described in the present invention is as follows:
第一，工作人员将批量待检验的导光板竖向放置在水平底板31上，批量的导光板位于水平底板的后部。Firstly, the workers vertically place the batches of light guide plates to be inspected on the horizontal base plate 31 , and the batches of light guide plates are located at the rear of the horizontal base plate.
第二，第一伸缩气缸32和第二伸缩气缸36动作，第一伸缩气缸通过第一连接杆33驱动第一吸盘34向后水平移动，第二伸缩气缸通过第二连接杆驱动第二吸盘37向后水平移动，第一吸盘和第二吸盘同时吸取批量导光板中最前端的导光板；之后，在第一伸缩气缸的驱动下，第一吸盘34和第二吸盘37带着导光板水平向前移动至水平底板的前端处，此时，被第一吸盘和第二吸盘吸附的导光板已从黑底背光玻璃12的下方经过而来到黑底背光玻璃的下方的前方且位于LED灯条13的正下方。Second, the first telescopic cylinder 32 and the second telescopic cylinder 36 act, the first telescopic cylinder drives the first sucker 34 to move horizontally backward through the first connecting rod 33, and the second telescopic cylinder drives the second sucker 37 through the second connecting rod Moving backward horizontally, the first suction cup and the second suction cup simultaneously absorb the frontmost light guide plate in the batch of light guide plates; then, driven by the first telescopic cylinder, the first suction cup 34 and the second suction cup 37 take the light guide plate horizontally Move forward to the front end of the horizontal bottom plate. At this time, the light guide plate absorbed by the first suction cup and the second suction cup has passed from the bottom of the black backlight glass 12 to the front of the bottom of the black backlight glass and is located on the LED light bar. 13 directly below.
第三，第一提升机构21中的第一气缸214和第二提升机构22中的第二气缸同时伸展，第一夹块215和第二夹块相向移动而夹持住位于LED灯条13正下方的导光板；之后，第一电机和第二电机同时动作，分别驱动第一丝杆212和第二丝杆旋转，第一丝杆和第二丝杆分别驱动第一升降块213和第二升降块沿第一导向槽216和第二导向槽向上移动，第一升降块和第二升降块带动导光板上升至黑底背光玻璃12的正前方，此时，通过黑底背光玻璃吸光的原理，LED光射入导光板中，工作人员能清楚的检验产品上的异常。Thirdly, the first air cylinder 214 in the first lifting mechanism 21 and the second air cylinder in the second lifting mechanism 22 extend simultaneously, and the first clamping block 215 and the second clamping block move toward each other to clamp the LED light bar 13 at the front The light guide plate below; after that, the first motor and the second motor act at the same time, respectively driving the first screw rod 212 and the second screw rod to rotate, and the first screw rod and the second screw rod drive the first lifting block 213 and the second screw rod respectively The lifting block moves upward along the first guide groove 216 and the second guide groove, and the first lifting block and the second lifting block drive the light guide plate to rise to the front of the black backlight glass 12. At this time, the light is absorbed by the black backlight glass , LED light is injected into the light guide plate, and the staff can clearly inspect the abnormality on the product.
以上内容仅为本发明的较佳实施方式，对于本领域的普通技术人员，依据本发明的思想，在具体实施方式及应用范围上均会有改变之处，本说明书内容不应理解为对本发明的限制。The above content is only the preferred implementation mode of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation mode and application scope. limits.
