[0017] The first slide rod and the piston rod make synchronous circular motions. When the first slide rod is located in the wide groove, the piston rod is located in the eight grooves and the one groove; when the first slide rod is located in the first narrow groove, the piston rod is located in the two grooves, the three grooves and the four grooves; when the first slide rod is located in the outwardly expanding groove, the piston rod is located in the five grooves; when the first slide rod is located in the second narrow groove, the piston rod is located in the six grooves and the seven grooves; when the first slide rod is located in the inwardly receiving groove, the piston rod is still located in the seven grooves.
[0018] The present invention has the following beneficial effects:
[0019] 1. The display performance detection system, the workbench drives the detection table to rotate, the first slide bar slides from the wide slot into the first narrow slot, so that the first slide bar drives the two first calibration plates to approach each other, the first spring is compressed, and the first wedge block and the second wedge block are used in cooperation to drive the second calibration plate to move, so as to push the display body and limit its position, and at the same time, the piston rod slides from the first slot into the second slot, and the piston rod sliding in the second slot drives the piston to move downward, and the suction component sucks air from the bottom of the display body, so that the display body is adsorbed on the detection table due to negative pressure, and the display body is prevented from moving and tilting during the detection process as much as possible, and then the piston rod continues to slide in the second slot, the piston stops moving downward, and the piston rod continues to drive the detection plate to press down on the soft flat cable, and when the piston rod slides in the third slot, the detection plate is always pressed on the soft flat cable, so that the display body is powered on and the first detection is performed on it;
[0020] The first slide bar continues to slide in the first narrow groove, and the piston rod slides from the third groove into the fourth groove, so that the piston rod drives the detection plate to move up a small distance and separate from the flexible flat cable. The piston rod slides from the fourth groove into the fifth groove, so that the detection plate is always separated from the flexible flat cable. At the same time, the first slide bar slides from the first narrow groove into the outer expansion groove, so that the first slide bar drives the detection table and the display screen body thereon to deviate outward together. When the first slide bar slides in the second narrow groove, the piston rod first slides in the sixth groove, so that the piston rod drives the detection plate to press down on the flexible flat cable again, and the position where the piston rod contacts the flexible flat cable does not overlap. When the first slide bar continues to slide in the second narrow groove, the piston rod slides in the seventh groove, so that the detection plate is always pressed on the flexible flat cable, thereby performing a second detection on the display screen body.
[0021] When the first slide bar slides in the inner groove, the offset detection platform is reset, and finally the first slide bar slides back into the wide groove. Under the action of the rebound force of the first spring, the first slide bar drives the first calibration plate and the second calibration plate to reset. At the same time, the piston rod slides in the eight grooves, driving the detection plate to rise and reset, thereby maximizing the detection efficiency of the display screen body.
[0022] 2. In the display performance detection system, the two first calibration plates close to each other squeeze the extension plate into the middle plate, and the second spring is compressed to reduce the length of the second calibration plate. After the squeezing of the second calibration plate by the first calibration plate is released, the extension plate can be easily reset under the action of the rebound force of the second spring, and the second calibration plate can be avoided as much as possible to cause obstruction to the two first calibration plates close to each other, thereby facilitating the positioning detection of the display body.
[0023] 3. In the display performance detection system, when the piston rod drives the piston and the retaining ring to move downward, the retaining ring squeezes and deforms the elastic sheet to pass over the elastic sheet, and then the piston is pressed down on the block, and the restored elastic sheet contacts the retaining ring. The piston rod continues to move downward so that the third spring is stretched, and the detection plate is pressed down on the soft flat cable. Then the piston rod drives the detection plate to move up a small distance, and the upward distance is not enough to completely restore the stretched third spring. At the same time, the elastic sheet limits the retaining ring from moving upward when the piston rod moves up a small distance, and the suction component is prevented from releasing pressure as much as possible, so that the display body is always adsorbed on the detection table, which is not easy to affect the detection of the display body.

[0048] When the first slide bar 140 slides in the inner groove 205, the offset detection platform 120 is reset, and finally the first slide bar 140 slides back into the wide groove 201. Under the action of the rebound force of the first spring 150, the first slide bar 140 drives the first calibration plate 130 and the second calibration plate 160 to reset. At the same time, the piston rod 230 slides in the eight grooves 268, driving the detection plate 240 to rise and reset, thereby improving the detection efficiency of the display body 10 as much as possible, and solving the existing detection system as much as possible. It is usually necessary to manually take the display screen to the detection position, and the detection plate is pressed down to contact the soft cable on the display screen to power on the display screen. However, manual detection one by one is time-consuming and labor-intensive, which can easily lead to the problem of low detection efficiency.
[0049] Embodiment 2: This embodiment is intended to promote the solution of the problem that the second calibration plate 160 easily obstructs the two first calibration plates 130 close to each other, thereby easily affecting the positioning detection of the display screen body 10. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 The two first calibration plates 130 are symmetrically arranged on the upper side of the detection platform 120, and the second calibration plate 160 includes an intermediate plate 161, two telescopic plates 162 slidably inserted on both sides of the intermediate plate 161, and a second spring 163 fixedly connected between the intermediate plate 161 and the telescopic plate 162. The length of the intermediate plate 161 is smaller than the width of the display body 10, and the ends of the two telescopic plates 162 are respectively in contact with the adjacent first calibration plates 130, and the intermediate plate 161 is fixedly connected to the second sliding rod 170.
[0050] In the present embodiment: the two first calibration plates 130 close to each other squeeze the telescopic plate 162 into the middle plate 161, and the second spring 163 is compressed to reduce the length of the second calibration plate 160. After the squeezing of the second calibration plate by the first calibration plate 130 is released, the telescopic plate 162 is easy to reset under the action of the rebound force of the second spring 163, and the second calibration plate 160 is avoided as much as possible to cause obstruction to the two first calibration plates 130 close to each other, thereby facilitating the positioning detection of the display screen body 10.
[0051] Embodiment 3: This embodiment aims to solve the problem that when the piston rod 230 drives the detection plate 240 to move upward a small distance, it is easy to drive the piston 220 upward to release the pressure of the suction component 250, which affects the adsorption of the display screen body 10, thereby easily affecting the detection of the display screen body 10. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1 , Figure 2 , Figure 3 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 A retaining ring 242 is fixedly mounted on the lower side of the piston 220, and a stopper 243 and an elastic sheet 244 are fixedly mounted on the inner wall of the cylinder 210. The stopper 243 is arranged on the upper side of the elastic sheet 244. The number of the stoppers 243 and the elastic sheets 244 are both set to be several. The distance between the stoppers 243 is greater than the outer diameter of the retaining ring 242 and smaller than the diameter of the piston 220, and the distance between the elastic sheets 244 is smaller than the outer diameter of the retaining ring 242.
[0052] In this embodiment: during the process of the piston rod 230 driving the piston 220 and the retaining ring 242 to move downward, the retaining ring 242 squeezes and deforms the elastic sheet 244 to pass over the elastic sheet 244, and then the piston 220 is pressed down on the stopper 243, and the restored elastic sheet 244 contacts the retaining ring 242, and the piston rod 230 continues to move downward so that the third spring 231 is stretched, and the detection plate 240 is pressed down on the flexible flat cable 12, and then the piston rod 230 drives the detection plate 240 to move up a small distance, and the upward movement distance is not enough to make the stretched third spring 231 completely recover. At the same time, through the resistance restriction of the elastic sheet 244 to the retaining ring 242, the piston 220 is prevented from moving up when the piston rod 230 moves up a small distance, and the suction component 250 is prevented from releasing pressure as much as possible, so that the display screen body 10 is always adsorbed on the detection table 120, so as not to easily affect the detection of the display screen body 10.
