[0026] As shown in Figure 6 , the turnover clamping piece 2408 includes a positioning block 24081, the positioning block 24081 is provided with a penetrating fixing hole, the fixing hole of the positioning block 24081 is sleeved on the outer surface of the guide rod 2407, and the top of the positioning block 24081 is provided with a positioning groove for placing the product 100. The bottom of the positioning block 24081 is fixedly connected with a positioning cylinder 24082, and the output end of the positioning cylinder 24082 is fixedly connected with a clamping block 24083.

[0027] When the product 100 is sent to the turnover frame 2406 by the lifting assembly 23, the product 100 will first fall into the positioning groove on the top of the positioning block 24081, and the positioning cylinder 24082 is operated to pull the clamping block 24083 to move, and the inner clamping surface of the clamping block 24083 is in contact with the top and outer wall of the product 100, so as to fix the product 100 on the positioning block 24081.

When the product 100 passes through the code scanning station, the upper and lower surfaces of the product 100 are scanned by the upper code scanner 32 and the lower code scanner 33 respectively. If the product code is on the top, it is identified by the upper code scanner 32; if it is on the bottom, it is identified by the lower code scanner 33.

[0029] The conveying line 31 tail end is fixedly connected with a blocking piece 34 on both sides. The blocking piece 34 can block the product 100 on the conveying line 31, so as to facilitate the orderly grabbing and carrying of the product 100 by the carrying robot 50 to the idle test station.

[0030] As shown in Figure 1 and Figure 8 , the jig flat plate mechanism 60 is at least two, and the jig flat plate mechanism 60 is used to carry and fix the product 100 for electrical performance test. When one jig flat plate mechanism 60 is testing, the carrying robot 50 can feed or take away the tested product 100 from the other idle jig flat plate mechanism 60, reducing the waiting time and improving the test efficiency.

[0031] The jig flat plate mechanism 60 includes a bottom frame 61, the top of the bottom frame 61 is fixedly connected with a push cylinder 62, the output end of the push cylinder 62 is fixedly connected with a push plate 63, and the top of the push plate 63 is fixedly connected with a load plate 64 for carrying the product 100; The bottom frame 61 is provided with a test needle plate 67, and the probes on the test needle plate 67 correspond to the test points of the product 100; The push plate 63 is embedded with a guide sleeve 65, and the top of the bottom frame 61 is fixedly connected with a guide column 66, and the guide sleeve 65 is slidingly connected to the outer surface of the guide column 66.

[0032] After the product 100 is placed on the carrier plate 64 by the transfer robot 50, the push cylinder 62 is operated to pull down the push plate 63 and the carrier plate 64, so that the product 100 is stably lowered. At this time, the guide sleeve 65 slides on the outer surface of the guide column 66. When the product 100 is lowered to the lowest point, the test point at the bottom of the product 100 contacts the probe on the test needle plate 67 and generates a certain contact pressure. At this time, the power-on and function test can be started. After the test is completed, the push cylinder 62 is retracted to pull up the product 100 and separate the contact with the test needle plate 67, so as to facilitate the transfer robot 50 to take away.

[0033] As shown in Figure 1 and Figure 9 , the central control screen automatic visual auxiliary test equipment further comprises a visual test mechanism 70, which is arranged above the jig flat plate mechanism 60. The visual test mechanism 70 is used for visual detection of the product 100. The visual test mechanism 70 comprises a fixed frame 71, and at least one industrial camera 72 is fixedly connected to the bottom of the fixed frame 71. After the test point of the product 100 contacts the test needle plate 67, the product 100 is in a power-on state. At this time, the test program controls the display screen of the product 100 to display test images such as solid color images, grid images, gradient images, etc. The industrial camera 72 photographs the display screen after being lighted, collects the display image, and transmits the collected image to an image processing system. The collected image is compared and analyzed with a preset standard template, so as to judge whether the display screen has appearance defects such as bright and dark spots, color spots, uneven display, and line defects.

[0034] As shown in Figure 1 , the transfer robot 50 is a six-axis robot, and the end effector of the transfer robot 50 is provided with a gripper and a marker pen.

[0035] Specifically, when the product 100 is a defective product, the transfer robot 50 takes out the product 100 from the jig flat plate mechanism 60, and controls the marker pen to draw a clear mark on the frame or back of the product 100.

[0036] As shown in Figure 1 , the tail end of the snapshot camera module 40 is provided with a second turnover mechanism 80, which is used to turn over the product 100 to a flowing-out posture after the test is completed. The structure and working principle of the second turnover mechanism 80 are the same as or similar to those of the first turnover mechanism 20. When the transfer robot 50 places the product 100, which has completed all tests, on the second turnover mechanism 80, the second turnover mechanism 80 performs a turnover action opposite to that when feeding. If the screen needs to face upward during the test, the screen needs to face downward to protect the screen or adapt to the packaging requirements during the flowing-out, the second turnover mechanism 80 will turn over the product 100 from the test posture to the flowing-out posture.

[0037] The tail end of the second turnover mechanism 80 is provided with a discharging assembly 90, which is used to convey the product 100 to a subsequent packaging station, a sorting station or a storage area.

[0038] The working principle of the present application is as follows: the product 100 to be tested is placed on the feeding assembly 22, the lifting assembly 23 lifts and transfers the product 100 from the feeding assembly 22 to the turnover assembly 24, the turnover clamp 2408 clamps and fixes the product 100, and then the driving member 2404 drives the turnover frame 2406 to rotate, so that the product 100 is automatically and uniformly turned from an initial disordered posture to a preset test posture; After the posture adjustment is completed, the product 100 is placed back and flows into the code scanning mechanism 30 and is carried by the conveying assembly 31, the upper code scanner 32 and the lower code scanner 33 located above and below the conveying assembly 31 simultaneously scan the upper and lower surfaces of the product 100, and automatically read the identity code thereof; After the code scanning is completed, the handling robot 50 grasps the positioned product 100 from the conveying assembly 31 according to the coordinate information provided by the snapshot camera module 40, and places the product 100 on the loading plate 64 of an idle jig plate mechanism 60, after the placement is completed, the push cylinder 62 operates to drive the loading plate 64 and the product to descend through the push plate 63, so that the test points at the bottom of the product 100 are in contact with the probes on the test needle plate 67 to establish electrical connection, and the electrical performance test is started. At this time, the industrial camera 72 photographs the product 100 displaying the test image after being powered on, and the collected image is transmitted to the image processing system for defect analysis; When one jig plate mechanism 60 is testing, the handling robot 50 can feed another idle jig plate mechanism 60, or take out the product 100 that has completed the test from the jig plate mechanism 60; After the test is completed, the handling robot 50 takes out the product 100 from the jig plate mechanism 60, if the test result is bad, the marker pen at the end of the handling robot 50 will make a mark on the product 100. Subsequently, the handling robot 50 places the product on the second turnover mechanism 80, and adjusts the product 100 from the test posture to a specified posture suitable for flowing out or packaging through the second turnover mechanism 80. Finally, the product 100 is conveyed to the next process through the discharging assembly 90, and the entire automatic test process is completed.
