In addition, when dust adheres to the display screen during testing, it can easily affect the testing results.

[0033] This utility model provides a display screen testing device, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, the display screen testing equipment includes a testing platform 1, a conveying mechanism 2, a testing mechanism 3, and a positioning platform 4. The conveying mechanism 2 is mounted on the testing platform 1 for conveying the display screen 100. The conveying mechanism 2 includes a support frame mounted on the testing platform 1, two rollers rotatably mounted on the support frame, a drive motor for driving the rollers to rotate, and a conveyor belt tensioned on the two rollers. The display screen 100 is placed on the conveyor belt for conveying, and the conveyor belt is used to convey the display screen 100 from one end of the testing platform 1 to the other end. The positioning platform 4 is fixedly connected to the upper end of the testing platform 1 and is located on one side of the conveying mechanism 2. The positioning platform 4 has a positioning groove 41 on its upper surface, with a gap between it and the conveyor belt. The display screen 100 is placed in the positioning groove 41 for testing. The positioning platform 4 has an opening on the side facing the conveyor mechanism 2 so that the positioning groove 41 can communicate with the conveyor belt. At the same time, the upper surface of the positioning groove 41 is flush with the upper surface of the conveyor belt of the conveyor mechanism 2 so that the display screen 100 can move back and forth between the positioning groove 41 and the conveyor belt of the conveyor mechanism 2. The testing mechanism 3 is set at the upper end of the testing platform 1. After the display screen 100 enters the positioning groove 41, the testing mechanism 3 can test the display screen 100 in the positioning groove 41.

[0034] Meanwhile, a first pushing mechanism 5 and a second pushing mechanism 6 are also provided on the testing table 1. Both the first pushing mechanism 5 and the second pushing mechanism 6 include a pushing cylinder and a pushing plate. The pushing cylinder is installed on the testing table 1, and the pushing plate is connected to the pushing cylinder. The pushing cylinder controls the horizontal movement of the pushing plate. The first pushing mechanism 5 is located on the side of the conveying mechanism 2 away from the positioning table 4, and the first pushing mechanism 5 can push the display screen 100 on the conveyor belt into the positioning groove 41 of the positioning table 4. The second pushing mechanism 6 is located on the positioning table 4 away from the conveying mechanism. On one side of 2, the second pushing mechanism 6 can push the display screen 100 in the positioning groove 41 on the positioning table 4 onto the conveyor belt; thereby, the first pushing mechanism 5 and the second pushing mechanism 6 move the display screen 100 back and forth between the conveyor belt and the positioning groove 41 to realize automatic loading and unloading of the display screen 100, that is, movement between the conveyor belt and the inspection station; a protective layer is provided on the side of the pushing plate facing the display screen 100, and the protective layer is made of a flexible material, such as a rubber layer, to protect the display screen 100 when pushing it.

[0035] To improve the stability of the second pusher mechanism 6 during installation, such as Figure 5 As shown, an installation groove 42 is provided on the positioning platform 4. The installation groove 42 is located on the side of the positioning platform 4 away from the conveyor belt. The second pushing mechanism 6 is set in the installation groove 42. The positioning platform 4 frees up the pushing space for the second pushing mechanism 6, making full use of the space and improving the overall compactness of the installation of the testing equipment.

[0036] In this embodiment, the detection mechanism 3 includes a mounting frame 31, a movable frame 32 slidably mounted on the mounting frame 31, a detection frame 33 slidably mounted on the movable frame 32, and a camera 34 mounted at the bottom of the detection frame 33. The camera 34 captures images of the surface of the display screen 100 and transmits them remotely, allowing for remote acquisition of real-time images of the display screen 100 for detection. No on-site personnel are required for detection operations, resulting in high detection efficiency. A first cylinder 35 is mounted on the mounting frame 31, which is connected to the movable frame 32 to control the horizontal movement of the movable frame 32, thereby enabling the first cylinder 35 to drive the camera to move horizontally at the top of the display screen 100. A second cylinder 36 is mounted on the movable frame 32, which is connected to the detection frame 33 to control the lifting and lowering movement of the detection frame 33, thereby enabling the second cylinder 36 to drive the camera 34 to move vertically closer to the surface of the display screen 100.

[0037] To ensure the stability of the movement of the movable frame 32 and the testing frame 33, a first slide rail is provided on the mounting frame 31. The first slide rail is horizontally set, and one end of the movable frame 32 is embedded in the first slide rail and slides on the first slide rail. A second slide rail is provided on the movable frame 32. The second slide rail is vertically set, and one end of the testing frame 33 is embedded in the second slide rail and slides on the second slide rail. The movement of the movable frame 32 and the testing frame 33 is limited by the first slide rail and the second slide rail to ensure that their movement is smooth.

[0038] In order to clean the dust on the display screen 100, such as Figure 6 and Figure 7 As shown, an air supply plate 37 is provided on the testing frame 33, and an air supply channel is provided inside the air supply plate 37. A jet nozzle 39 connected to the air supply channel is installed at the bottom of the air supply plate 37. The jet nozzle 39 sprays gas to blow away the dust and impurities adsorbed on the display screen 100 (in other embodiments, in order to ensure the dust removal effect, a dust suction mechanism can also be provided on the side of the positioning platform 4, which, together with the jet nozzle 39, can prevent the gas from returning to the display screen 100 after blowing). An air supply hole 38 connected to the air supply channel is provided at the top of the testing frame 33. The air supply hole 38 can be connected to an air pump through a pipeline. A connector is provided on the connecting pipe of the air pump. The connector can be inserted into the air supply hole 38 and threadedly connected to the air supply hole 38, so that the air pump is connected to the air supply channel. When the air pump supplies air, the gas enters the air supply hole 38 through the pipeline and enters the air supply channel. It is then sprayed from top to bottom by the jet nozzle 39 onto the display screen 100 to clean the surface of the display screen 100.

[0039] In order to make the air supply plate 37 removable, the air supply plate 37 is set to be detachable. Specifically, a slot 331 is opened on the side of the test frame 33, one end of the air supply plate 37 is inserted into the inside of the slot 331, and at least one side of the air supply plate 37 is left outside the slot 331, so that the air nozzle 39 is left outside the air supply plate 37, making it convenient to install and remove the air supply plate 37.

[0040] To facilitate cleaning of the air supply channel, an air groove 371 is provided on the top of the air supply plate 37. After the air supply plate 37 is inserted into the slot 331, the air groove 371 and the inner wall of the slot 331 cooperate to form a sealed air supply channel. A through hole is provided at the end of the air supply channel to communicate with the air nozzle 39, so that the air groove 371, i.e. the air supply channel, can be easily cleaned after the air supply plate 37 is pulled out.

[0041] The working principle of this utility model is as follows: The display screen 100 is placed on one side of the conveyor belt for conveying. When it reaches the position of the positioning table 4, the conveying stops. The first pushing mechanism 5 is started to push the display screen 100 on the conveyor belt onto the positioning groove 41 of the positioning table 4. When the display screen 100 is pushed to fit against one side of the positioning groove 41, the first pushing mechanism 5 returns. Then, the detection mechanism 3 is started to move the detection frame 33 to the upper end of the display screen 100 so that the camera 34 and the air nozzle 39 can move to the upper end of the display screen 100. The air pump is started to blow away and clean the dust and impurities on the display screen 100. Then, the camera 34 is moved to acquire images for remote detection. After the detection is completed, the second pushing mechanism 6 is started to push the display screen 100 on the positioning table 4 back onto the conveyor belt. The conveyor belt is started to convey the display screen 100 after the detection is completed.

[0042] This utility model, through the arrangement of positioning platform 4, conveying mechanism 2, first pushing mechanism 5 and second pushing mechanism 6, can automatically push the display screen 100 back and forth on the conveyor belt and positioning platform 4, eliminating the need for manual loading and unloading of the display screen 100, and meeting the function of continuous detection, thus improving detection efficiency; at the same time, it can blow air to clean the surface of the display screen 100 during detection, ensuring the detection effect.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
