In addition, the monitoring assembly comprises a vision sensor 32, a first fixing column 33, a second fixing column 34, a spring 35 and a sliding column 36 with protrusions, wherein the vision sensor 32 is provided with a first through hole 37, the first fixing column 33 and the second fixing column 34 are fixedly connected with the connecting seat 31 and are oppositely arranged, the sliding column 36 with protrusions is in sliding connection with the first fixing column 33, two ends of the spring 35 are respectively fixedly connected with the first fixing column 33 and the sliding column 36 with protrusions, the spring is positioned between the first fixing column 33 and the sliding column 36 with protrusions, the second fixing column 34 is provided with a second through hole 38, and the sliding column 36 with protrusions penetrates into the first through hole 37 and the second through hole 38. When the vision sensor 32 needs to be replaced, the sliding column slides towards the first fixing column 33 through the protrusion, the spring 35 is compressed, the sliding column moves out of the first through hole 37 and the second through hole 38, a gap is reserved between the sliding column 36 and the vision sensor 32, and the vision sensor 32 is taken out for replacement, so that replacement and installation are facilitated.
The working/implementation/use principle of the invention is as follows: FOG liquid crystal display that output still puts 10min in each regional automation of arm stand 2 circumferencial direction needs to carry out impedance test passes through material loading transport mechanism 3 transmits, this moment transparent sucking disc 7 is located material loading transport mechanism 3's top, when waiting to examine FOG liquid crystal display to transparent sucking disc 7 below, one of them elevating gear 11 rotates, drives another gear 11 and two rack 10 rotates, realizes elevating frame 9 drives transparent sucking disc 7 moves down and contacts and wait to examine FOG liquid crystal display, vacuum generator 6 action forms the negative pressure absorption and waits to examine FOG liquid crystal display. The transparent suckers 7 are used for adsorbing the corresponding FOG liquid crystal screen to be detected, the lifting frame 9 moves upwards to drive the transparent suckers 7 for adsorbing the FOG liquid crystal screen to be detected to move upwards, the mechanical arm upright posts 2 rotate to drive the transparent suckers 7 of the FOG liquid crystal screen to be detected to rotate to the upper portion of the test table 4, the mechanical arm upright posts 2 are used for realizing that the transparent suckers 7 rotate to different stations for processing, a mechanical arm structure is not required to be designed for corresponding stations, the cost is reduced, the lifting frame 9 moves downwards to drive the transparent suckers 7 to move downwards, the transparent suckers 7 are loosened to enable the FOG liquid crystal screen to be detected to be located on the test table 4, and through the identification components, the movement of the identification pen 23 in the front-back, up-down and-left-right directions is achieved to carry out unqualified area identification, and after the test is finished, indicator lamps at corresponding positions display green lights or red lights according to test results. After all the tests are finished, the transparent sucker 7 adsorbs the detected FOG liquid crystal screen to move upwards, the mechanical arm upright post 2 rotates again to enable the detected FOG liquid crystal screen to be located above the blanking transmission mechanism 5, the lifting frame 9 moves downwards, the transparent sucker 7 is loosened to enable the detected FOG liquid crystal screen to be located on the blanking transmission mechanism 5 and transmitted according to the detection results, if silver paste resistance values of all positions of the detection results are qualified, the blanking transmission mechanism 5 transmits the detected FOG liquid crystal screen to the next procedure to be processed, and if the detection results have that silver paste resistance values of one position are unqualified, the baffle 13 acts to guide the unqualified FOG liquid crystal screen to the defective product area of the reworked transmission mechanism 12 to be reworked. The lifting pieces can independently act to carry out adsorption test according to the detection result of the monitoring component, so that the application range is wider.
Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present invention and not for limiting the same, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the present invention, which is intended to be covered by the claims of the present invention.
