Description

Technical Field

[0001] The utility model relates to the technical field of coating cover plate spraying, in particular to a coating cover plate spraying device. Background Art

[0002] With the development of technology, cover plates of various display devices, such as mobile phones, tablets, and TVs, play an increasingly important role in people's daily lives. The screens of these devices usually use coated cover plates to protect the display surface and enhance the viewing experience. In order to reduce the reflection and glare of external light, an anti-glare film layer is usually applied on the cover plate. However, the traditional anti-glare film coating process has the problem of uneven coating thickness, resulting in color difference or white fog, affecting the appearance and performance of the product.

[0003] For example, the Chinese utility model patent (CN201820561890.7) discloses an automatic spraying device. The utility model relates to an automatic spraying device, including a side panel spraying device, a bottom panel spraying device, a conveying device and a control device. The side panel spraying device and the bottom panel spraying device are respectively arranged at the inlet and outlet ends of the conveying device. The side panel spraying device and the bottom panel spraying device are fixedly connected to the conveying device. The control device is electrically connected to the side panel spraying device and the bottom panel spraying device. The control device is located below the conveying device. The control device is used to control the opening and closing of the side panel spraying device and the bottom panel spraying device. The automatic spraying device of the utility model realizes automatic spraying, effectively saves labor costs and time costs, improves spraying efficiency, and does not affect the subsequent demolding process.

[0004] 1) In the existing coating cover plate anti-glare film spraying process, the anti-glare liquid is usually poured into the spraying equipment, and the spraying operation is performed by adjusting the pressure and nozzle angle of the sprayer. However, due to factors such as airflow interference, the number and movement of the spray nozzles, and the cover plate fixing method, the thickness of the sprayed anti-glare film layer is uneven, resulting in color difference or white fog.

[0005] 2) When spraying the traditional anti-glare liquid, only one spray nozzle sprays from left to right, and the cover plate keeps moving forward, so this method is relatively inefficient. In this patented solution, the cover plate does not need to move. There are 4 nozzles on it, which can move left and right and forward and backward in the left and right and upper and lower quarter areas respectively to spray the surface of the cover plate evenly. While improving the efficiency, it also avoids uneven spraying or liquid accumulation caused by the vibration of the conveyor belt during the transmission process. Utility Model Content

[0006] Based on this, it is necessary to provide a coating cover plate spraying device to address the above-mentioned technical problems. Through the shielding effect of the lifting cover, the influence of the airflow on the spraying liquid is reduced, and the uniformity of the spraying is improved. By setting multiple nozzles and moving the spraying in different areas, the spraying efficiency is improved. At the same time, it also avoids the uneven spraying caused by the vibration of the conveyor belt. The coated cover plate is fixed by a vacuum adsorption device.

[0057] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0058] Please refer to Figure 1-Figure 3, a coating cover plate spraying device, comprising a supporting mechanism 1, a coating mechanism 2, an adsorption fixing mechanism 3 for implementing negative pressure suction of the coating cover plate 42, and a linear displacement mechanism 4 for guiding the displacement change of the coating mechanism 2;

[0062] The linear displacement mechanism 4 improves the spraying angle and range of the coating mechanism 2;

[0063] The coating mechanism 2 is composed of a lifting cover 21 , a spraying device 22 and a spray head structure 23 .

[0066] The support mechanism 1 includes two side wall support plates 11 arranged on both sides of the ground, and the two side wall support plates 11 are supported and connected by a linear displacement mechanism 4;

[0067] The adsorption fixing mechanism 3 includes a booster suction fan 31 which is located opposite to the nozzle in the nozzle structure 23, and the air outlet of the booster suction fan 31 is arranged at the bottom of the booster suction fan 31;

[0068] Four independent negative pressure air suction ports are provided on the top of the booster suction fan 31 . The top ends of the negative pressure air suction ports are vertically connected to a lifting guide pipe 32 . A vacuum adsorption head 33 is provided at the top end of the lifting guide pipe 32 .

[0069] The lifting cover 21 provided in this embodiment makes the thickness uniformity of the anti-glare film layer better, and avoids color difference or white fog caused by uneven film layer. First, the lifting cover 21 is used to cover the cover plate as much as possible before spraying to avoid horizontal interference of the front, back, left and right airflows on the sprayed mist liquid, thereby avoiding horizontal deviation of the spray liquid and causing horizontal accumulation of liquid.

[0070] The automatic column passing device provided in Example 1 is further optimized, specifically, Figure 4 As shown, the top ends of the four vacuum adsorption heads 33 can be lifted and lowered in tandem;

[0071] A lifting slot 211 is provided on the side wall of the lifting cover 21 , a sliding rod 212 is provided at the top of the lifting slot 211 , and one end of the sliding rod 212 is connected to the spraying equipment 22 to slide the lifting cover 21 up and down.

[0072] Through the above structural design, when spraying on the conveyor belt 41, the vacuum adsorption head 33 and the lifting guide tube 32 are used to implement the vacuum adsorption force, and the four vacuum holes under the cover plate are adsorbed to keep the cover plate fixed during the spraying process.

[0073] The automatic column passing device provided in Example 1 or 2 is further optimized, such as Figure 1-6 As shown, a linear displacement frame 12 is provided in the middle of the side walls of the two side wall support plates 11 , and a partition plate 13 is provided in the middle of the linear displacement frame 12 .

[0074] A traction rod 14 is transversely arranged at the middle of the top of the lifting cover 21, a connecting rod 15 is connected to the middle of the top of the traction rod 14, a square plate 16 is installed at the middle of the top of the connecting rod 15, and a connecting rod 17 is arranged in the middle, and one end of the connecting rod 17 is connected to one end of the linear displacement frame 12;

[0075] When spraying on the conveyor belt 41, the vacuum adsorption head 33 and the lifting guide tube 32 are used to implement the vacuum adsorption force, and the four vacuum holes under the cover plate are adsorbed, so that the cover plate is fixed and kept motionless during the spraying process, avoiding the problem of uneven local spraying or uneven displacement caused by vibration or jamming of the equipment during operation, and making spraying more convenient.

[0076] The automatic column passing device provided in the above embodiments is further optimized, such as Figure 7 As shown, the linear displacement mechanism 4 includes a conveyor belt 41 arranged in the middle of the two side wall support plates 11, and a coating cover plate 42 is provided on the surface of the conveyor belt 41.

[0077] The use process provided by the utility model is as follows: Step 1: First, the personnel need to prepare the coating (anti-glare liquid) with the coating cover plate 42 spray material and pour it into the storage tank of the spraying equipment 22, and store it for use;

[0078] Step 2: In order to prevent the spray material from scattering when spraying the surface of the coating cover plate 42, the coating cover plate 42 is shielded around by utilizing the lifting groove 211 of the lifting cover 21 and the inner drive of the sliding rod 212 to avoid air flow interference and form a closed space;

[0079] After that, the vacuum adsorption device is turned on, and the negative pressure gas suction on the roof is performed according to the position of the vacuum adsorption head 33 and the lifting guide tube 32, and the coating cover plate 42 is adsorbed and fixed through multiple vacuum holes;

[0080] Then, the control device controls the nozzle of the spraying device 22 and the coated cover plate 42 to remain relatively still, and the conveyor belt 41 must stop moving. Different from the traditional single nozzle, this solution uses 4 nozzles distributed in the four quarter areas of the upper, lower, left and right of the cover plate. The nozzles can move forward, backward, left and right in their respective areas to achieve uniform spraying on the surface of the cover plate, improve spraying efficiency, and avoid uneven spraying or accumulation of liquid medicine caused by vibration of the conveyor belt 41.

[0081] Step 3: After the spraying is completed, each operating device is reset and powered on, the lifting cover 21 is raised, and the vacuum adsorption device releases the coated cover plate 42 that has been sprayed, and the coated cover plate 42 is then transferred to the next station along with the restarted conveyor belt 41;

[0082] Step 4: The size of the lifting cover 21 is replaceable according to the size and shape of the coated cover 42. Because the screen sizes of different mobile phones are naturally different, and there are many types of car-mounted display screens, the size and shape of the lifting cover 21 are adjusted to adapt to the coated cover 42 of different specifications. At the same time, the number of nozzles and the moving trajectory of the lifting guide tube 32 can also be adjusted according to actual needs to achieve the best spraying effect.
