Description

Technical Field

[0001] This utility model relates to the field of anti-fingerprint coating spraying technology, and in particular to an automatic spraying device for anti-fingerprint coating. Background Technology

[0002] Applying an AF (anti-fingerprint) coating to tempered glass significantly reduces the adhesion of contaminants such as grease and sweat, effectively preventing fingerprints and handprints and maintaining a clean and aesthetically pleasing appearance. This coating possesses excellent hydrophobic and oleophobic properties, not only improving the smoothness of the touch but also enhancing the glass's stain resistance and ease of cleaning; daily wiping restores its cleanliness. Simultaneously, the AF coating reduces the scattering of reflected light, improving light transmittance and display clarity.

[0003] In existing technologies, the anti-fingerprint oil spraying process is mostly carried out in open or semi-enclosed environments, lacking effective isolation and protection measures. This causes atomized oil droplets to easily diffuse in the air, forming suspended particulate matter that contaminates the production environment. Long-term exposure to such environments may pose health risks to operators' respiratory system and overall health if inhaled. Furthermore, the scattered coating material easily adheres to equipment and surrounding workpieces, affecting operational cleanliness and product yield. Utility Model Content

Detailed Implementation

[0017] 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.

[0018] Please see Figure 1-6This utility model provides an embodiment of an automatic spraying device for anti-fingerprint coating, including a first platform 11, on which a reciprocating feeding assembly 5 and a spraying cylinder 21 slide. The first platform 11 is also provided with an atomizing nozzle 62, which is coaxially arranged with the spraying cylinder 21. A circular tempered glass film 61 can be coaxially inserted into the spraying cylinder 21. The atomizing nozzle 62 is used to spray AF anti-fingerprint oil onto the circular tempered glass film 61. The first platform 11 is provided with a spacer column 12, and a second platform 13 is provided on the spacer column 12. The second platform 13 is used to support a lifting assembly 4. The lifting assembly 4 includes a drive unit and a clamping plate 41 on the output end of the drive unit. An air pipe 71 is installed on the clamping plate 41, and a suction nozzle 72 is installed at one end of the air pipe 71. The suction nozzle 72 is used to adsorb the circular tempered glass film 61 in the spraying cylinder 21. The suction nozzle 72 can place the circular tempered glass film 61 on the belt 51 of the reciprocating feeding assembly 5. The lifting assembly 4 drives the suction nozzle 72 to precisely descend into the spraying cylinder 21, adsorbing the circular tempered glass film 61 that has been coated with AF anti-fingerprint oil, and smoothly transferring it onto the conveyor belt 51 of the reciprocating unloading assembly 5, completing the unloading action. This design realizes the automatic removal and transportation of the coated product, reducing manual intervention. The suction nozzle 72 and the tempered glass film are vacuum adsorbed, which reduces scratches on the surface of the circular tempered glass film 61. Spraying inside the spraying cylinder 21 reduces the dispersion of AF anti-fingerprint oil in the air.

[0019] Please see Figure 1-4 A further embodiment of this solution involves an inner sealing ring 211 attached to the inside of the spraying cylinder 21. The inner diameter of the sealing ring 211 is smaller than the diameter of the circular tempered glass film 61. The edge of the circular tempered glass film 61 can fit against the sealing ring 211 inside the spraying cylinder 21. The sealing ring 211 prevents the circular tempered glass film 61 inside the spraying cylinder 21 from contacting the atomizing nozzle 62. The cooperation between the sealing ring 211 and the circular tempered glass film 61 inside the spraying cylinder 21 increases the sealing performance and prevents the circular tempered glass film 61 from falling completely onto the atomizing nozzle 62, thus acting as a limiting element.

[0020] Please see Figure 2-5 A further embodiment of this solution is as follows: the reciprocating feeding assembly 5 also includes a support plate 52 for supporting the conveyor belt 51. A slider 521 is installed at the bottom of the support plate 52, and a slide rail 522 corresponding to the slider 521 is provided on the first platform 11. The guiding structure of the slider 521 and the slide rail 522 ensures that the support plate 52 moves smoothly between the receiving position and the conveying path, ensuring the accuracy of receiving material in the reciprocating feeding assembly 5, ensuring that the tempered film can accurately fall into the designated position during feeding, and improving feeding accuracy and system operation reliability.

[0021] Please see Figure 2-3A further solution based on this embodiment is as follows: A first limiting plate 53 is provided on the first platform 11, and a guide rod 531 is provided on the first limiting plate 53. The guide rod 531 can be inserted into the bearing plate 52. A spring 532 is sleeved on the outer diameter of the guide rod 531. The spring 532 is used to push the belt 51 away from the spraying cylinder 21. The pre-tightening structure of the spring 532 allows the bearing plate 52 to automatically reset to a position away from the spraying area when it is not pushed by the cam 111, avoiding spatial interference with the material feeding action of the lifting component 4 or the suction nozzle 72, and improving the safety of equipment operation; at the same time, it provides an initial position reference for the next material receiving action, ensuring the stability and repeatability of the action cycle. The cam 111 mechanism enables precise reciprocating motion control of the support plate 52. It pushes the belt 51 directly below the suction nozzle 72 only when material needs to be received, and automatically retracts after material feeding is completed, effectively saving space and preventing the belt 51 from interfering with other components. By controlling the rotation phase of the cam 111 through the motor, the feeding sequence of the lifting component 4 can be precisely matched to achieve a highly coordinated automated feeding process.

[0022] Please see Figure 3-5 A further solution based on this embodiment is as follows: a contact plate 523 is provided at the bottom of the support plate 52, a notch is provided on the first platform 11 to avoid the contact plate 523, a cam 111 is rotatably connected on the first platform 11, the cam 111 is used to push the belt 51 to the bottom of the suction nozzle 72 to receive the material, and a second motor is installed on the cam 111 to drive the cam 111 to rotate.

[0023] Please see Figure 1-3 A further solution based on this embodiment is as follows: The lifting assembly 4 includes a mounting plate 131 on the second platform 13 and a first motor 47 on the mounting plate 131. The output end of the first motor 47 is connected to one end of a first connecting rod 46. The other end of the first connecting rod 46 is rotatably connected to one end of a second connecting rod 45. The other end of the second connecting rod 45 is rotatably connected to an L-shaped plate 43. A limiting block 42 is installed on the second platform 13. The limiting block 42 is rotatably connected to the L-shaped plate 43. A limiting cylinder 44 slides on the L-shaped plate 43. The limiting cylinder 44 is rotatably connected to the clamping plate 41. This linkage mechanism converts the rotational motion of the motor into the vertical lifting motion of the clamping plate 41, avoiding the reduction in motor life caused by frequent forward and reverse switching of traditional motors. Compared with pneumatic components, it also avoids sealing failure caused by frequent movement.

[0024] Please see Figure 1-3 A further solution based on this embodiment is as follows: the limiting block 42 is provided with a guide opening, which is used to restrict the vertical movement of the clamping plate 41. The guide opening further constrains the movement trajectory of the L-shaped plate 43 or the limiting cylinder 44, forcing the clamping plate 41 to move in the vertical direction, ensuring that the suction nozzle 72 maintains a stable posture during the downward adsorption and lifting process, avoiding the tempered film from falling off or scratching the cylinder wall, and ensuring the safety and reliability of the feeding process.

[0025] For another embodiment of the lifting assembly 4, please refer to [link / reference]. Figure 6 A further solution based on this embodiment is as follows: the lifting assembly 4 includes a cylinder 48 mounted on the second platform 13, and a clamping plate 41 is connected to the output end of the cylinder 48. The cylinder 48 drive has the advantages of rapid response, simple control, and stable output force, which can realize the rapid lifting action of the suction nozzle 72 assembly, and at the same time reduce the need for parts assembly and reduce the assembly burden.

[0026] Working principle: First, the circular tempered glass film 61 to be sprayed is manually placed into the spraying cylinder 21 or fed in by the preceding automated equipment to achieve material loading. Under the action of gravity, the tempered glass film falls to the spraying station, and its edges are limited and supported by the sealing ring 211 inside the spraying cylinder 21 to ensure accurate positioning and maintain a safe distance from the atomizing nozzle 62 above. During the spraying stage, the atomizing nozzle 62 is activated to evenly spray AF anti-fingerprint oil onto the surface of the tempered glass film. Since the spraying process is completed in a relatively closed cylinder, paint splashing and evaporation are effectively reduced, improving the cleanliness of the spraying operation environment. After spraying, the lifting assembly 4 activates, and the drive unit, through a linkage mechanism or cylinder 48, drives the clamping plate 41 to descend vertically, causing the suction nozzle 72 to contact and vacuum-adsorb the surface of the tempered glass film. Subsequently, the lifting assembly 4 rises, removing the circular tempered glass film 61 from the spraying cylinder 21. The control system activates the second motor to drive the cam 111 to rotate. The cam 111 pushes the support plate 52 to overcome the preload of the spring 532, moving it forward along the slide rail 522. This allows the conveyor belt 51 of the reciprocating discharge assembly 5 to precisely reach the receiving position directly below the suction nozzle 72. The suction nozzle 72 breaks the vacuum, and the circular tempered glass film 61 falls onto the conveyor belt 51, completing the unloading process. The cam 111 continues to rotate, causing the spring 532 to reset and the support plate 52 to return to its original position. The conveyor belt 51 continues to rotate while following the movement of the support plate 52, conveying the sprayed circular tempered glass film 61 to the next process. The control device, control method, and corresponding circuit and pneumatic connections, as well as the generation and breaking of vacuum, are all existing technologies, and their working principles will not be elaborated here.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
