Description

Technical Field

[0001] The invention relates to the technical field of display screen production, and in particular to a display screen assembly system. Background Art

[0002] There are many types of displays, including visual displays, auditory displays, tactile displays and olfactory displays. According to the characteristics of the information displayed, it can be divided into dynamic displays and static displays, qualitative displays and quantitative displays. According to the different manufacturing materials, it can be divided into cathode ray tube displays (CRT), plasma displays PDP, liquid crystal displays LCD, etc. The display generally includes the following structures: Liquid crystal module: Glass substrate: Inside is liquid crystal and grid-shaped printed circuit. The timing circuit is used to generate the timing and voltage required to control the deflection of liquid crystal molecules; lamp tube: produces white light source. Backlight: reflects the light generated by the lamp tube onto the LCD screen; control board: The control board plays a signal conversion role. Convert various input format signals into fixed output format signals. For example, the input signal for a 1024 x768 screen can be 640×480, 800×600, 1024×768, etc., and finally converted into an output format of 1024×768; inverter: generates high voltage to light up the lamp tube.

[0003] When assembling a common display screen, it is necessary to put the LCD screen, control board and inverter into an outer box, and then use the glue dispensing process to fix the LCD screen to the box shell, and connect the LCD screen to the control board and inverter, and complete the assembly after passing the subsequent inspection. However, the general display screen assembly system has the following defects when assembling the display screen: First, the glue is not applied evenly on the display screen shell, resulting in glue overflow during installation of the LCD screen, affecting the appearance of the edge of the LCD screen, or the glass substrate is not firmly bonded due to the discontinuous glue, affecting the assembly quality, and the glue solidification time is relatively slow, resulting in a long time of placement before transportation, affecting the assembly efficiency; Second, when the LCD screen of the display screen is assembled with the display screen shell, it is necessary to In order to connect the LCD screen to the control board and the inverter, the assembly structure needs to be turned over. Conventional turning over is generally done manually, and manual operation is likely to increase the damage rate of the LCD screen and the display screen shell, and manual turning over is also time-consuming and labor-intensive. In addition, some LCD screens are large in size, and manual handling and installation are also troublesome, and it is not easy to quickly align the correct position, affecting assembly efficiency; third, when assembling the display screen, since the LCD screen needs to be conductively connected to the control board and the inverter, a soldering process is required. Due to the high temperature of the soldering process, it is difficult for the traditional assembly system to quickly cool down the area around the solder, which will cause the temperature of the solder to drop slowly after melting, resulting in a strong flow ability, which is easy to damage the display screen components.

Soft rubber is used, so the LCD screen will not be damaged during transfer. When the transport component transfers the LCD screen, the fixed motor 58 and the vacuum suction cup 57 are started, and the vacuum suction cup 57 adsorbs one side of the bottom of the LCD screen to facilitate movement. The fixed motor 58 drives the threaded rod 54 to rotate, the threaded rod 54 drives the moving seat 56 to move, and the moving seat 56 drives the vacuum suction cup 57 to move, and the LCD screen is transferred to the display housing 12. This process can quickly install a larger LCD screen and prevent the LCD screen from being damaged by bumps during installation, thereby improving the protection effect of the LCD screen.

[0027] Two groups of multi-stage hydraulic rods 59 are provided and symmetrically distributed on both sides of the bottom of the assembly platform 1. The fixed plate 60 is fixedly connected to the end of the multi-stage hydraulic rod 59. The rubber baffle plate 61 and the electric telescopic rod 63 are both fixedly connected to the upper surface of the fixed plate 60. The outer wall of the rubber baffle plate 61 and the inner wall of the display housing 12 are on the same vertical plane perpendicular to the ground. The electric heating plate 62 is arranged on the inner side of the rubber baffle plate 61. The maximum temperature of the electric heating plate 62 is 40 degrees. The electric telescopic rod 63 is arranged on the inner side of the rubber baffle plate 61. The roller frame 64 is fixedly connected to the top of the electric telescopic rod 63, and the elastic roller 65 is arranged on the roller frame 64. During use, when dispensing glue, by starting the multi-stage hydraulic rod 59, the multi-stage hydraulic rod 59 drives the fixed plate 60 to rise, so that the fixed plate 60 drives the glue baffle plate 61 to fit with the inner wall of the display housing 12 to prevent the glue from overflowing. In addition, the electric heating plate 62 can heat the glue dispensing area to accelerate the drying of the glue and improve the assembly efficiency. In addition, when the assembled display screen needs to be taken out, by starting the electric telescopic rod 63, the electric telescopic rod 63 drives the roller frame 64 to rise, and the elastic roller 65 on the roller frame 64 abuts against the bottom of the assembled display screen, and then pushes it out, and it is quickly removed by the elastic roller 65.
