[0023] A first magnetic plate is arranged between the electric plug 23 and the receiving part 202; a second magnetic plate is arranged between the signal plug 24 and the receiving part 202; there is magnetic adsorption between the first magnetic plate, the second magnetic plate and the receiving part 202; when in use, the positions of the electric plug 23 and the signal plug 24 on the side of the receiving part 202 can be adjusted by the first magnetic plate and the second magnetic plate. It should be pointed out that the conductive wire and the signal wire are both made of high temperature resistant materials, and sufficient stretching margin is reserved; in addition, the power supply 231 and the signal transmitter 241 are protected by a heat-insulating shell; since the circulating trolley 21 does not need to stay in the aging box 1 for a long time, electronic equipment such as the power supply 231 can be used normally.

[0024] like Figures 7 and 8As shown, a pair of blocking plates 12 are arranged on both sides of the aging box 1, and a first hydraulic cylinder 13 installed on the surface of the aging box 1 is arranged above the blocking plate 12, and a connecting piece is arranged between the output end of the first hydraulic cylinder 13 and the blocking plate 12; the bottom end of the blocking plate 12 is at the same height as the top end of the circulating track 2; during the test, the first hydraulic cylinder 13 is started, and the blocking plate 12 is driven to move through the connecting piece, and the pair of blocking plates 12 blocks the through-opening 11 of the aging box 1, thereby reducing the heat loss rate in the aging box 1 during the test, which is beneficial to the rapid heating of the subsequent test.

[0025] A pair of blocking plates 12 are provided with sliding notches 121 on opposite sides, and a filling block 123 is inserted into the sliding notch 121. A tension spring 122 is arranged between the top of the filling block 123 and the inner top wall of the sliding notch 121. An electromagnet 14 installed on the side of the aging box 1 is arranged above the blocking plate 12, and a magnetic block with the same magnetic property as the electromagnet 14 after power is turned on is arranged inside the filling block 123; when the pair of blocking plates 12 are butt-joined with each other, the electromagnet 14 is powered on, and a magnetic block with the same magnetic property as the electromagnet 14 after power is turned on is arranged inside the filling block 123; therefore, the electromagnet 14 generates magnetic repulsion to the filling block 123 inside the sliding notch 121, causing the filling block 123 to move downward and embed into the interior of the circulating track 2, thereby partially filling the through-opening 11 located in the circulating track 2, and ensuring that the through-opening 11 is completely blocked.

[0026] like Figures 3 to 6 As shown, a pair of receiving notches 221 are provided on opposite sides of a pair of clamping parts 201, a receiving plate 222 is provided inside the receiving notch 221, a guide rod 223 is provided on the side of the receiving plate 222, the end of the guide rod 223 passes through the receiving notch 221, and a compression spring 224 is provided between the receiving plate 222 and the receiving notch 221; when installing the display screen on the positioning frame 22, for display screens of different sizes, the receiving plate 222 in the receiving notch 221 can be used to clamp both sides of the display screen, and the clamping force is provided by the compression spring 224, so as to ensure the installation of display screens of different sizes on the positioning frame 22.

[0027] An inclined guiding portion is provided at the end of the receiving plate 222; the inclined guiding portion is inclined toward the two sides of the positioning frame 22; when the display screen is installed on the positioning frame 22 through the loading assembly 3, the loading assembly 3 carries the display screen into between a pair of receiving plates 222 and will first squeeze the inclined guiding portion of the receiving plate 222, and then be clamped by the receiving plate 222 to avoid interference by the end of the receiving plate 222 during the loading process.

A third hydraulic cylinder 381 is arranged at the center, and the output end of the third hydraulic cylinder 381 passes through the loading plate 38. A main vacuum suction cup 382 is arranged at the output end of the third hydraulic cylinder 381. A fourth hydraulic cylinder 39 with multiple output ends passing through the loading plate 38 is arranged at the non-center of the top of the loading plate 38. An auxiliary vacuum suction cup 391 is arranged at the output end of the fourth hydraulic cylinder 39. When loading, the conveyor 4 conveys the display screen to be tested to the bottom of the loading plate 38, and then the second hydraulic cylinder 34 is started, and the second hydraulic cylinder 34 is started. The pressure cylinder 34 drives the loading plate 38 to move downward through the fixed block 35 and the connecting frame 37, and stops when the main vacuum suction cup 382 contacts the liquid crystal part of the display screen below, and then moves on the loading slide rail 32 through the loading trolley 33 to carry the display screen to one side of the positioning frame 22, and then drives the loading plate 38 to rotate through the connecting frame 37 by the servo motor 36. The loading plate 38 drives the display screen to remain vertical, and then stops after entering between a pair of clamping parts 201 of the positioning frame 22. It should be pointed out that during installation, the plug head 23 and the signal plug 24 are automatically inserted into the specified position; automatic loading is realized, and the test efficiency is improved. In addition, when display screens of different sizes are adsorbed by the main vacuum suction cup 382, ​​they can also be adaptively adsorbed by the auxiliary vacuum suction cup 391. The use position of the auxiliary vacuum suction cup 391 is selected based on the actual size of the display screen to ensure that the display screen is fully adsorbed and the adsorption position is increased to the maximum, so as to avoid damage to the display screen due to excessive local force.

[0029] The conveyor 4 includes a shell and a conveyor belt; a pair of fifth hydraulic cylinders 41 are arranged on both sides of the shell, and a push plate 42 is arranged at the output end of the fifth hydraulic cylinder 41; when the conveyor 4 stops conveying the display screen, the fifth hydraulic cylinder 41 can drive the push plate 42 to push the display screen, so that the display screen is in a precise horizontal position, which is convenient for precise docking in the subsequent loading process, specifically the docking and insertion of the unplugged head 23 and the signal plug 24 at the plug-in position on the display screen; in addition, a baffle 44 is arranged at the unloading end of the conveyor belt, and a control motor 43 installed on the shell is arranged at the end of the baffle 44; the longitudinal position of the display screen can be blocked by the baffle 44, thereby further refining the position of the display screen; the baffle 44 can be controlled to rotate by the control motor 43, thereby controlling the blocking position of the baffle 44 on the display screen, and has a wide range of applications.
