[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0021] See also Figures 1 to 3 , including a fixture body 1, the left half of the fixture body 1 is provided with a PCB adapter module 2, the right half is provided with a groove 11, the groove 11 is provided with a replaceable module 3, the PCB adapter module 2 is provided with a suction cup plate 22, the suction cup plate 22 is provided with a vacuum suction cup, the screen body 21 is fixed on the suction cup plate by the suction cup, the replaceable module 3 can replace different modules according to the different models of the screen body 21, the replaceable module 3 is provided with a cylinder 32, the left end of the cylinder 32 is connected to the screen FPC cable 35, the screen FPC cable 35 is connected to the screen body 21, and the back of the PCB adapter module 2 is provided with a reverse connector 23. A first connector 37 is provided on one side of the cylinder 32 on the replaceable module 3, and a second connector 38 is provided on the replaceable module 3 near the first connector 37. The right end of the screen FPC cable 35 is connected to the product connector 34, and the cylinder 32 is connected through the product connector 34. A multi-tube joint 5 is provided on the right side of the bottom of the fixture body 1 , and the multi-tube joint 5 is connected to a pipeline 4 for controlling the direction of the first gas joint 31 .
[0022] The cylinder 32 is started to push the screen FPC cable 35 to the left, and then push it downward. At this time, the screen is fixed and pressed by the FPC cable. Then, the FPC signal is output to the first connector 37 through the product connector 34, and then the first connector 37 is connected to the second connector 38. The output FPC signal is then connected to the reverse connector 23 of the PCB adapter module 2 by the second connector 38. The reverse connector 23 is inserted into the device to light up the product, so as to detect whether the screen is a good product.
[0023] Since the module arranged on the right half of the fixture body 1 is a replaceable module 3, when facing different types of screens, different corresponding modules can be replaced to adapt to different screen models, so that the same parts can be reused to reduce costs.
[0024] By using the multi-tube joint 5, various pipes 4 of the fixture can be effectively connected to one place, and the gas from the gas source can be evenly distributed to various parts of the screen to ensure the uniformity of the screen light source. The multi-tube joint 5 can adjust the air pressure delivered to various areas of the screen to meet the needs of different screen sizes and models, and it also facilitates the removal and reinstallation of the air pipe, so as to facilitate the needs of the replaceable module 3 for fast replacement of screens of different models.
[0025] The working principle is: the screen body 21 is placed on the suction cup plate on the fixture body 1 through the mechanical arm of the external device, and then the screen body 21 and the screen FPC cable 35 are adsorbed by the vacuum suction cup, and then the cylinder 32 is started, the cylinder 32 pushes the gas rod to move to the left, and then presses the screen body 21 product downward. The screen body 21 product contacts the PCB through the probe, and the PCB transmits the signal to the reverse connector 23 at the bottom of the fixture, and the reverse connector 23 is plugged with the device PG to realize the connection between the device PG and the screen body 21 product connector 34, so as to achieve the purpose of detecting whether the product screen is a good product.
[0026] Furthermore, there are four vacuum suction cups, which are evenly arranged in the areas of the suction cup plate corresponding to the four corners of the screen body 21. The four vacuum suction cups can effectively vacuum the screen body 21, and can effectively adsorb and fix the screen.
[0027] Furthermore, a second air joint is provided on the longer side of the suction cup plate, and an air pipe groove is provided at the PCB adapter module 2 corresponding to the second air joint, and the air pipe groove is communicated with the end of the pipe 4. U-shaped pipe clamps 36 for fixing the air pipe are also evenly arranged in the pipe 4. The use of the air pipe groove can protect the air pipe of the second air joint, and the use of the U-shaped pipe clamp 36 can fix and protect the air pipe of the second air joint in the pipe 4, so as to prevent the air pipe from having a problem that the vacuum suction cup does not adsorb the screen firmly due to the air pipe pipe 4.
[0028] The replaceable display screen fixture provided by the utility model has the following advantages:
[0029] By opening grooves on the jig and using replaceable modules as modules for testing mobile phone screens, the remaining identical areas of the jig can be reused to save costs. At the same time, the screen can be effectively fixed by using cylinders and vacuum suction cups, and the display can be quickly positioned and fixed, thereby improving detection efficiency.
