[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This embodiment provides a display screen production line, which includes (see reference) Figure 1The quantitative wiping assembly shown includes a substrate 1, a wiping mechanism for wiping is provided below the substrate 1, and a delivery mechanism for quantitatively delivering wiping liquid to the wiping mechanism through a pipeline is provided above the substrate 1.

[0021] In some embodiments, the delivery mechanism includes: a transfer tank 2 located above the substrate 1 to provide alcohol to the wiping mechanism, and a fluid control valve 201 located below the substrate 1 and connecting the transfer tank 2 and the wiping mechanism. When the wiping clamp 3 needs to be replenished with wiping liquid, the wiping liquid in the transfer tank 2 will flow through the pipeline to the fluid control valve 201. The fluid control valve 201 will then deliver the liquid storage tank 101 through the pipeline to the wiping clamp 3 to replenish the wiping clamp 3, thereby ensuring the wiping effect of the wiping clamp 3 on the gold fingers of the display screen. The fluid control valve 201 can quantitatively control the wiping liquid entering the pipeline to ensure that when the wiping clamp 3 is replenished with wiping liquid, there will not be too much wiping liquid, which would prevent the wiping liquid on the display screen from evaporating quickly.

[0022] In some embodiments: the wiping mechanism includes two wiping clamps 3 arranged opposite to each other, and the two wiping clamps 3 can be connected to the conveying mechanism. A movable plate 301 is provided on one side of the wiping clamp 3, and a driving device 302 for pushing the movable plate 301 is provided on the surface of the movable plate 301. An infrared sensor is installed below the substrate 1. The infrared sensor is electrically connected to the driving device 302. The surface of the wiping clamp 3 can be a fiber cloth. After the wiping liquid enters the pipeline, it will enter the wiping clamp 3 through the pipeline, so that the fiber cloth on the wiping clamp 3 can absorb the wiping liquid delivered by the pipeline, thereby replenishing the wiping clamp 3 with wiping liquid. When the infrared sensor senses the display screen, the infrared sensor will send a signal to the two sets of driving devices 302. An electrical signal is sent to activate the two sets of drive devices 302. After activation, the two sets of drive devices 302 will push the moving plate 301 towards the display screen. When the moving plate 301 moves, it will move the wiping clip 3 together, so that the two wiping clips 3 can touch the top and bottom of the display screen respectively, thereby clamping and wiping the gold fingers on the display screen. When the infrared sensor does not detect the display screen, it will control the drive device 302 to shut down, so that the drive device 302 will move the moving plate 301 away from the display screen, thereby retracting the wiping clip 3. When the gold fingers of the display screen pass by the wiping clip 3, the wiping clip 3 will wipe the gold fingers of the display screen to prevent dust from being on the gold fingers of the display screen.

[0023] In some embodiments: a liquid storage tank 101 is provided on one side of the substrate 1, and a pneumatic control valve 102 is installed on the top of the substrate 1. The liquid storage tank 101 and the pneumatic control valve 102 are connected by a pipeline, and the pneumatic control valve 102 is connected to the transfer tank 2 by a pipeline. After the pneumatic control valve 102 is activated, it will draw the alcohol in the liquid storage tank 101 into the pipeline. After the alcohol enters the pipeline, it will flow from the pneumatic control valve 102 to the transfer tank 2 through the pipeline connection between the pneumatic control valve 102 and the transfer tank 2, thereby replenishing the alcohol in the transfer tank 2.

[0024] In some embodiments: a solenoid valve 103 is provided on the top of the substrate 1, and a liquid level sensor 104 is mounted on the surface of the transfer tank 2. The output terminal of the liquid level sensor 104 is electrically connected to the input terminal of the solenoid valve 103, and the output terminal of the solenoid valve 103 is electrically connected to the input terminal of the pneumatic control valve 102. When the liquid level sensor 104 detects that the alcohol level in the transfer tank 2 is too low, the liquid level sensor 104 can transmit an electrical signal to the solenoid valve 103. The solenoid valve 103 receives the electrical signal and then controls the pneumatic control valve 102 to start, so that the pneumatic control valve 102 can pump the alcohol in the storage tank 101 to the transfer tank 2. When the liquid level sensor 104 detects that the alcohol level in the transfer tank 2 is sufficient... An electrical signal can be sent to the solenoid valve 103, causing the solenoid valve 103 to close the pneumatic control valve 102, thus stopping the alcohol in the storage tank 101 from entering the transfer tank 2. The upper liquid level sensor 141 can detect the highest liquid level in the transfer tank 2. When the wiping liquid reaches the highest liquid level in the transfer tank 2, it will send an electrical signal to the solenoid valve 103, causing the solenoid valve 103 to close the pneumatic control valve 102. The lower liquid level sensor 142 can detect the lowest liquid level. When the lower liquid level sensor 142 detects that the liquid level in the transfer tank 2 has reached the lowest level, the solenoid valve 103 will control the pneumatic control valve 102 to start, so that the pneumatic control valve 102 will replenish the wiping liquid in the storage tank 101 into the transfer tank 2.

[0025] In some embodiments, a funnel 105 is provided above the liquid storage tank 101. The funnel 105 is connected to the liquid storage tank 101. When it is necessary to replenish the wiping liquid in the liquid storage tank 101, the wiping liquid can be introduced into the funnel 105, so that the liquid storage tank enters the liquid storage tank 101 through the funnel 105, thereby replenishing the wiping liquid in the liquid storage tank 101.

[0026] In some embodiments, a mounting plate 106 is provided below the substrate 1. The substrate 1 and the mounting plate 106 are installed together by bolts. The connection and fixation between the substrate 1 and the mounting plate 106 can ensure that the substrate 1 is installed stably, thereby ensuring that the transfer tank 2 can work normally.

[0027] The specific working process for wiping the gold fingers of the display screen according to this utility model is as follows:

[0028] After the wiping fluid enters the pipeline, it flows into the wiping clamp 3, allowing the fibrous cloth on the wiping clamp 3 to absorb the wiping fluid delivered by the pipeline, thus replenishing the wiping clamp 3 with wiping fluid. When the infrared sensor detects the display screen, the infrared sensor sends an electrical signal to the two sets of drive devices 302, causing the two sets of drive devices 302 to start. After the two sets of drive devices 302 start, they will push the moving plate 301 towards the display screen. When the moving plate 301 moves, it will move the wiping clamp 3 along with it, so that the two wiping clamps 3 can touch the top and bottom of the display screen respectively, thereby clamping and wiping the gold fingers on the display screen. When the infrared sensor does not detect the display screen, it will control the drive device 302 to shut down, causing the drive device 302 to move the moving plate 301 away from the display screen, thereby retracting the wiping clamp 3. When the gold fingers of the display screen pass through the wiping clamp 3, the wiping clamp 3 will wipe the gold fingers of the display screen to prevent dust from floating on the gold fingers of the display screen.

[0029] The procedure for replenishing alcohol to the wiping clip 3 is as follows:

[0030] When the wiping fluid needs to be replenished in the wiping clip 3, the wiping fluid in the transfer tank 2 will flow through the pipeline to the fluid control valve 201. The fluid control valve 201 will then transport the liquid storage tank 101 through the pipeline to the wiping clip 3, thereby replenishing the wiping fluid in the wiping clip 3 and ensuring the wiping effect of the wiping clip 3 on the gold fingers of the display screen. The fluid control valve 201 can quantitatively control the amount of wiping fluid entering the wiping clip 3, thereby ensuring that when the wiping clip 3 is replenished with wiping fluid, there will not be too much wiping fluid, which would prevent the wiping fluid on the display screen from evaporating quickly.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
