Description

Technical Field

[0001] This utility model relates to the field of AF fingerprint liquid spraying device, specifically a multi-head AF fingerprint liquid spraying device. Background Technology

[0002] AF fingerprint liquid spraying equipment is a device used to spray anti-fingerprint coatings onto the surfaces of materials such as glass and plastic. This equipment can evenly spray the anti-fingerprint coating onto the product surface to achieve effects such as fingerprint resistance, stain resistance, and easy cleaning. AF coatings are usually made of materials with hydrophobic and oleophobic properties (such as fluorides or silane compounds) and are widely used in mobile phone screens, tablet computers, touch panels, displays, lens glass and other fields.

[0003] However, the current AF fingerprint liquid spraying equipment still has some shortcomings. For example, the nozzle spacing adjustment steps of the existing AF fingerprint liquid spraying equipment are relatively cumbersome, which means that when the staff needs to spray products of other sizes, they need to spend a long time adjusting the nozzle spacing. This interferes with the efficiency of the staff in adjusting the transition between different locations, and thus has certain defects in use.

[0004] Therefore, there is an urgent need to improve this shortcoming. This utility model is to study and improve the existing structure to provide a multi-head AF fingerprint liquid spraying device. Utility Model Content

[0005] The purpose of this invention is to provide a multi-head AF fingerprint liquid spraying device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-head AF fingerprint liquid spraying device, comprising a support bracket and a liquid storage tank. A conveying mechanism is installed on the inner surface of the support bracket, and a protective cover is fixedly installed on the top of the support bracket. An inspection door is rotatably installed on the outer side of the protective cover via a hinge. The liquid storage tank is fixedly installed on the top of the protective cover, and a drive motor is installed on the outer side of the liquid storage tank. A drive screw is installed on the output shaft of the drive motor via a coupling. Limiting guide rods are symmetrically fixedly installed on the inner surface of the liquid storage tank, and a spraying assembly is movably connected to the outer surface of the limiting guide rods.

[0007] Furthermore, the bottom of the protective cover is fixedly connected to the top of the support bracket, and the protective cover and the support bracket form a fixed structure.

[0008] Furthermore, the spraying assembly includes a support plate, a fixing block, a connecting seat, and a fixed liquid storage box. The fixing block is symmetrically installed on the top of the support plate, and the connecting seat is fixedly installed on the top of the fixing block. The interior of the connecting seat is adapted to and movably connected to the side of the drive screw, while the inner surface of the connecting seat is slidably connected to the side of the limiting guide rod.

[0009] Furthermore, the bottom of the fixing block is fixedly connected to the top of the bearing plate, and the top of the fixing block is fixedly connected to the bottom of the connecting seat, and the connecting seat forms a fixed structure with the bearing plate through the fixing block.

[0010] Furthermore, the spraying assembly also includes a fixed plate and a movable spraying mechanism, with the fixed plate symmetrically fixedly installed at the bottom of the support plate, and the movable spraying mechanism slidably connected to the bottom of the support plate.

[0011] Furthermore, the mobile spraying mechanism includes a mobile liquid storage box, a fixed base, a threaded adjusting rod, a T-shaped slider, a nozzle, and a liquid guide tube. The fixed base is fixedly connected to the outside of the mobile liquid storage box, and the threaded adjusting rod is rotatably connected inside the fixed base. T-shaped sliders are symmetrically installed on the top of the mobile liquid storage box, and nozzles are installed at equal intervals on the bottom of the mobile liquid storage box.

[0014] This utility model provides a multi-head AF fingerprint liquid spraying device, which has the following beneficial effects:

[0015] 1. This utility model, through the setting of a fixed liquid storage box and a mobile spraying mechanism, enables the spraying device to adopt a multi-set spray head synchronous operation setting. This allows the spraying component to simultaneously spray AF fingerprint liquid onto three products while moving along the top of the conveying mechanism, thereby greatly improving the processing efficiency of the spraying device. Furthermore, the setting of the drive screw and limit guide rod enables the drive motor to drive the spraying component to move back and forth along the inner surface of the protective cover during operation, thus allowing the spraying component to spray a more comprehensive range during the spraying operation.

[0016] 2. This utility model, through the setting of a fixed plate and a T-shaped slider, allows the operator to rotate the threaded adjustment rod inside the fixed base, thereby enabling the movable liquid storage box to move left and right along the bottom of the support plate. This achieves the purpose of quickly adjusting the distance between the movable and fixed liquid storage boxes, thus avoiding the situation where the operator needs to spend a long time adjusting the nozzle distance when spraying products of other sizes, which would interfere with the operator's efficiency in changing locations.

The bottom of the protective cover 3 is fixedly connected to the top of the support bracket 1, and the protective cover 3 and the support bracket 1 form a fixed structure. An inspection door 4 is rotatably installed on the outer side of the protective cover 3 via a hinge. The liquid storage tank 5 is fixedly installed on the top of the protective cover 3, and a drive motor 6 is installed on the outer side of the liquid storage tank 5. A drive screw 7 is installed on the output shaft of the drive motor 6 via a coupling. Limiting guide rods 8 are symmetrically fixedly installed on the inner surface of the liquid storage tank 5, and a spraying assembly 9 is movably connected to the outer surface of the limiting guide rods 8. The spraying assembly 9 includes a support plate 9. 1. A fixed block 92, a connecting seat 93, and a fixed liquid storage box 94 are provided. The fixed block 92 is symmetrically installed on the top of the support plate 91, and the connecting seat 93 is fixedly installed on the top of the fixed block 92. The bottom of the fixed block 92 is fixedly connected to the top of the support plate 91, and the top of the fixed block 92 is fixedly connected to the bottom of the connecting seat 93. The connecting seat 93 and the support plate 91 form a fixed structure through the fixed block 92. By setting the connecting seat 93 and the support plate 91 into a fixed structure, the connecting seat 93 can move the support plate 91 along the inner surface of the protective cover 3 more smoothly and stably. The interior of the connecting seat 93 is adapted to be movably connected to the side of the drive screw 7, and the inner surface of the connecting seat 93 is slidably connected to the side of the limit guide rod 8.

[0023] like Figure 2 and Figure 3As shown, a conveying mechanism 2 is installed on the inner surface of the support bracket 1, and a protective cover 3 is fixedly installed on the top of the support bracket 1. An inspection door 4 is rotatably installed on the outer side of the protective cover 3 via a hinge. A liquid storage tank 5 is fixedly installed on the top of the protective cover 3, and a drive motor 6 is installed on the outer side of the liquid storage tank 5. A drive screw 7 is installed on the output shaft of the drive motor 6 via a coupling. Limiting guide rods 8 are symmetrically fixedly installed on the inner surface of the liquid storage tank 5, and a spraying assembly 9 is movably connected to the outer surface of the limiting guide rods 8. The spraying assembly 9 also includes a fixed plate 95 and a movable spraying mechanism 96. The fixed plate 95 is symmetrically fixedly installed on the bottom of the support plate 91, and the movable spraying mechanism 96 is slidably connected to the bottom of the support plate 91. The movable spraying mechanism 96 includes a movable liquid storage box 961, a fixed seat 962, a threaded adjusting rod 963, a T-shaped slider 964, a nozzle 965, and a liquid guide tube 966. A fixed base 962 is fixedly connected to the side, and a threaded adjusting rod 963 is rotatably connected inside the fixed base 962. The end of the threaded adjusting rod 963 is rotatably connected to the inside of the fixed base 962, and the side of the threaded adjusting rod 963 is threadedly connected to the inner surface of the fixed plate 95. T-shaped sliders 964 are symmetrically installed on the top of the movable liquid storage box 961. The bottom of the T-shaped sliders 964 is fixedly connected to the top of the movable liquid storage box 961. The movable liquid storage box 961 forms a sliding structure with the support plate 91 through the T-shaped sliders 964. By setting the movable liquid storage box 961 and the support plate 91 into a sliding structure, the movable liquid storage box 961 moves more smoothly and stably along the bottom of the support plate 91.

A liquid guide tube 966 is fixedly installed on the side of the movable liquid storage box 961, and the other end of the liquid guide tube 966 is fixedly connected to the bottom of the liquid storage chamber 5.

[0024] In summary, this multi-head AF fingerprint liquid spraying device firstly... Figures 1 to 3As shown in the diagram, the operator opens the access door 4 by rotating the hinge. Then, the operator grasps the threaded adjusting rod 963 and rotates it inside the fixed base 962. At this time, through the sliding of the T-shaped slider 964 and the threaded connection between the side of the threaded adjusting rod 963 and the inside of the fixed plate 95, the movable liquid storage box 961 moves left and right along the bottom of the support plate 91. This allows for rapid adjustment of the distance between the movable liquid storage box 961 and the fixed liquid storage box 94. When the distance between the movable liquid storage box 961 and the fixed liquid storage box 94 is the same as the distance between the product to be sprayed, the rotation of the threaded adjusting rod 963 is stopped and the access door 4 is closed. Next, the operator places the product to be sprayed into the mold and turns on the conveying mechanism 2 and the drive motor 6. When mechanism 2 starts running, it moves the mold carrying the product into the interior of the protective cover 3. When the mold moves directly below the spraying component 9, the conveying mechanism 2 stops running. When the drive motor 6 starts running, it drives the drive screw 7 to rotate inside the liquid storage tank 5. At this time, through the connection of the connecting seat 93 and the guidance of the limit guide rod 8, the fixed block 92 drives the bearing plate 91 to move back and forth along the inner surface of the protective cover 3. This allows the nozzles 965 at the bottom of the fixed liquid storage box 94 and the movable liquid storage box 961 to automatically spray the product in the mold with AF fingerprint liquid. At this time, through the cooperation of the liquid guide tube 966, the AF fingerprint liquid stored in the liquid storage tank 5 automatically flows into the interior of the movable liquid storage box 961 and the fixed liquid storage box 94 for automatic replenishment.
