Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1

[0021] Please see Figures 1 to 3 This utility model is a testing device for LCD screens used in television production, including a conveyor frame 100 and an installation plate 102 installed inside it. A plug-in component 200 is provided at the front end of the upper surface of the conveyor frame 100. The plug-in component 200 includes a frequency band line 201 provided on the outside of the conveyor frame 100, and a first connector 202 and a second connector 203 provided at both ends of the frequency band line 201.

[0022] Specifically, conveyor rollers 101 are evenly spaced horizontally inside the conveyor frame 100, and a circuit board 103 is installed on the front of the upper surface of the mounting plate 102; the first connector 202 is inserted into the circuit board 103, and a housing 204 is sleeved on the outside of the second connector 203. A guide plate 205 is fixed at one bottom end of the housing 204; a flexible plate 206 is installed at the other bottom end of the housing 204, and an electric push rod 207 is installed on the outer wall of the flexible plate 206. The outer wall of the electric push rod 207 is installed on the surface of the conveyor frame 100 by a fastener.

[0023] Furthermore, multiple conveyor rollers 101 are provided, and a driving device can be provided on the outside of them for conveying the TV LCD screen to be tested. The circuit board 103 is an electronic component in TV production, which can be used for TV LCD screen testing during the production process. The two ends of the frequency band line 201 are respectively provided with a first connector 202 and a second connector 203, which are used to connect the circuit board 103 and the TV LCD screen to realize the testing of the TV LCD screen. The guide plate 205 can guide the second connector 203 to be inserted into the TV LCD screen when the second connector 203 moves. The flexible plate 206 is a flexible material that can support the second connector 203 and quickly rebound after bending. It cooperates with the frequency band line 201 to bend and be inserted into the TV LCD screen.

[0024] The operation process of this embodiment is as follows: During use, the assembled TV LCD screen is placed on the surface of the conveyor roller 101 inside the conveyor frame 100, and multiple TV LCD screens are conveyed sequentially by the conveyor roller 101. After the TV LCD screen is conveyed to the testing area, the electric push rod 207 is activated. The telescopic end of the electric push rod 207 extends and pushes the flexible plate 206 to move. The flexible plate 206 drives the second connector 203 inside the housing 204 to move. At this time, the second connector 203 continuously approaches the TV LCD screen to be tested. Then, under the guidance of the guide plate 205, the second connector 203 is inserted into the socket on the TV LCD screen. Then, the circuit board 103 is powered on to achieve the purpose of testing the TV LCD screen. After the test is completed, the electric push rod 207 is run again. The telescopic end of the electric push rod 207 retracts and drives the housing 204 to move, causing the second connector 203 inside to separate from the TV LCD screen, thereby completing the testing of the TV LCD screen and improving the testing efficiency of the TV LCD screen. Example 2

[0025] Please see Figure 2 and Figure 4 Based on Embodiment 1, the difference from the first embodiment is that a push-block assembly 300 is provided. The push-block assembly 300 includes a fixed frame 301 mounted on the surface of the mounting plate 102 and a motor 302 mounted on the rear end of the fixed frame 301. This solves the problem that existing LCD screen testing devices for television production require manual positioning of the transported LCD screens for testing purposes. However, manually and stably transporting LCD screens is time-consuming and labor-intensive, making it difficult to perform testing quickly and resulting in low work efficiency.

[0026] Specifically, the output shaft of the motor 302 passes through the bearing on the fixed frame 301 and is connected to the screw 302a via a coupling. The other end of the screw 302a is rotatably mounted on the inner wall of the fixed frame 301. A movable seat 303 is spirally sleeved on the outer wall of the screw 302a. Both ends of the upper surface of the movable seat 303 are fixedly provided with a first connecting rod 303a. The other end of the first connecting rod 303a is equipped with a push plate 304. A second connecting rod 303b is fixedly provided at one bottom end of the movable seat 303. The other end of the second connecting rod 303b is equipped with a slide 303c. The surface of the slide 303c is slidably mounted on the bottom of the baffle 305. The front and rear ends of the baffle 305 are slidably mounted on the inner wall of the conveyor frame 100.

[0027] Furthermore, the external thread on the outer wall of the screw 302a is screwed into the threaded hole on the movable seat 303, so the motor 302 drives the screw 302a to rotate. Under the action of the thread, the rotation of the screw 302a can drive the movable seat 303 to move along the inside of the fixed frame 301. The first connecting rod 303a connects the push plate 304 and the movable plate, and the second connecting rod 303b connects the slide 303c and the movable seat 303, which plays a role in connecting and transmitting. The bottom of the baffle 305 is provided with an inclined surface. When the slide 303c moves back and forth, it will push the baffle 305 to move up and down. The front and rear end faces of the baffle 305 are slidably installed on the inner wall of the conveyor frame 100, which plays a guiding role.

[0028] The operation process of this embodiment is as follows: When multiple TV LCD screens to be tested move inside the conveyor frame 100, the motor 302 is started. The output shaft of the motor 302 rotates, driving the screw 302a to rotate through the coupling. The external thread on the outer wall of the screw 302a is screwed into the threaded hole on the movable seat 303. Therefore, the rotation of the screw 302a will drive the movable seat 303 to move along the inside of the fixed frame 301 under the action of the thread. The movement of the movable seat 303 will drive the push plate 304 to move forward through the first connecting rod 303a, and the movement of the movable seat 303 will drive the slide 303c to move forward through the second connecting rod 303b. The slide 303c is slidably installed at the bottom of the baffle 305. Since the bottom of the baffle 305 is provided with an inclined surface, when the slide 303c moves horizontally back and forth, it will slide along the inclined surface, thereby moving the horizontal... The movement is converted into lifting or lowering the baffle 305, causing the baffle 305 to extend upwards or retract downwards, so that the baffle 305 moves above the conveyor frame 100 and acts as a barrier to the conveyed LCD screen. At the same time, the pusher 304 moves forward, pushing the LCD screen forward and closer to the detection component to complete the subsequent detection of the LCD screen. This ensures that the LCD screen is in the correct detection area, facilitating subsequent rapid detection. After the LCD screen detection is completed, the motor 302 is restarted, causing its output shaft to rotate in the opposite direction. Under the action of the screw 302a and the moving seat 303, the pusher 304 and the slide 303c are driven to move backwards. At this time, the limiting effect of the pusher 304 on the LCD screen is released, and the baffle 305 descends, allowing the LCD screen to move continuously, realizing continuous detection of the LCD screen.
