Description

Technical Field

[0001] This utility model relates to the field of dual-head dispensing technology, specifically a dual-head dispensing structure for lenses. Background Technology

[0002] In electronic smart devices such as mobile phones and tablets, the power of the camera function has become an important indicator of the phone's value. The performance of the camera function is determined by the lens, which is usually composed of a lens barrel, lens elements, and spacers. When fixing the lens with adhesive, a lens dispensing machine is required.

[0003] Traditional lens dispensing machines typically use a single dispensing head to dispense adhesive onto the lens. During operation, the dispensing head comes into contact with the lens barrel, which can cause the lens barrel to wobble and shift position. In addition, single-head dispensing machines have low dispensing efficiency, and the dispensing angle of traditional lens dispensing machines is relatively fixed, making it difficult to perform multi-angle dispensing operations. Utility Model Content

[0004] The purpose of this invention is to provide a dual-head dispensing structure for lenses, so as to solve the problem of lens dispensing machines being difficult to perform multi-angle dispensing operations as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lens dual-head dispensing structure, including a support frame, a Y-axis slide rail, and a moving plate. A KK module for driving the moving plate to move linearly is mounted on the top of the support frame. The moving plate is movably connected to the Y-axis slide rail of the KK module via a screw. A cylinder and a Z-axis slide rail are respectively mounted on the front part of the moving plate. A moving block for driving the moving seat is connected to the telescopic end of the cylinder. The moving seat is fixed to the surface of the moving block by bolts. A first slider is bolted to the side of the moving seat near the Z-axis slide rail, forming a sliding structure with the first slider. An angle dial is bolted to the outer surface of the moving seat, and angle values ​​are engraved on the surface of the angle dial. An arc-shaped groove for sliding the circular slider is formed on the front surface of the angle dial.

[0006] Preferably, the angle dial has equally spaced positioning holes for mounting a fixing seat, and the fixing seat is mounted on the surface of the angle dial by bolts and positioning holes.

[0007] Preferably, the rear part of the fixing seat near the arc-shaped groove is connected to a circular slider for moving the fixing seat, and the circular slider and the arc-shaped groove form a sliding structure.

[0008] Preferably, the fixing base has an adhesive dispensing container installed inside, and two sets of adhesive dispensing containers and fixing bases are provided on the angle dial.

[0009] Preferably, both sets of adhesive dispensing buckets are connected to dispensing heads for dispensing adhesive to the lens at their ends, and a mounting plate is bolted to the center surface of the angle dial.

[0010] Preferably, the front part of the mounting plate is equipped with a pressure bar slide rail and a proportional valve, and the outer side of the pressure bar slide rail is slidably connected to a second slider for driving the pressure bar body to rise and fall.

[0011] Preferably, the pressure bar body is installed at the bottom of the second slider, and the telescopic end at the bottom of the proportional valve is connected to the top of the second slider, so that the proportional valve can drive the second slider and the pressure bar body to move up and down.

[0012] Preferably, the inside of the pressure bar body is provided with a U-shaped groove for the dispensing head to pass through, and the pressure bar body is used to press and limit the lens barrel.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This dual-head dispensing structure allows for adjustment of the dispensing head angle. When the angle needs adjustment, the bolts between the fixing seat and the angle dial can be loosened, and the fixing seat can be pushed in a specified direction. This allows the fixing seat to move the circular slider within the arc-shaped groove. When the dispensing head on the fixing seat reaches the specified angle, the bolts are tightened to fix the position of the fixing seat. The position of the fixing seat can be adjusted according to the position of the positioning hole, enabling the dispensing head to perform multi-angle dispensing operations. The scale values ​​on the angle dial facilitate personnel confirmation of the dispensing head angle. A proportional valve controls the pressure, ensuring controllable and stable pressure on the pressure bar body, allowing the lens to be stably positioned during dispensing. Furthermore, the two sets of dispensing heads can perform multi-angle dispensing operations, suitable for dispensing different lenses. Additionally, the two sets of dispensing heads improve dispensing efficiency. Attached Figure Description

[0027] exist Figure 1 , Figure 2 , Figure 4 and Figure 6 In the middle: The front part of the mounting plate 16 is equipped with a pressure bar slide rail 17 and a proportional valve 18. The outer side of the pressure bar slide rail 17 is slidably connected to a second slider 19 for driving the pressure bar body 20 to rise and fall. The pressure bar slide rail 17 can guide the second slider 19.

[0028] exist Figure 1 , Figure 2 , Figure 4 and Figure 6 In the middle: the pressure bar body 20 is installed at the bottom of the second slider 19, and the telescopic end of the bottom of the proportional valve 18 is connected to the top of the second slider 19. The proportional valve 18 can drive the second slider 19 and the pressure bar body 20 to rise and fall.

[0029] exist Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 In the middle: The inside of the pressure bar body 20 is provided with a U-shaped groove 21 for the dispensing head 14 to pass through. The pressure bar body 20 is used to press and limit the lens barrel.

[0030] In practical implementation, lens dispensing machines are commonly used in the lens dispensing process of electronic devices. Traditional lens dispensing machines have difficulty performing multi-angle dispensing, and the lens barrel is prone to positional shifts during dispensing, thus affecting the dispensing efficiency. The KK module is a key transmission component in the field of industrial automation. Its core feature is that it achieves precise linear motion through integrated design. The KK module is a motor-driven moving platform, and its core structure includes a screw and a U-shaped linear guide rail. During the lens dispensing process, the lens barrel moves to the lens barrel camera position for imaging and positioning via a rotating assembly table. The KK module drives the moving plate 3 on the screw via a motor. Moving along the Y-axis slide rail 2, when the moving plate 3 moves to the designated position above the lens, the cylinder 4 can be activated. When the cylinder 4 is running, its telescopic end can drive the moving block 6 to move downwards. When the moving block 6 moves, it can drive the moving seat 7 and the first slider 8 to move. When the first slider 8 moves, it can slide through the Z-axis slide rail 5. When the moving seat 7 moves, it can drive the angle dial 9 to move, so that the pressure bar body 20 and the dispensing head 14 on the angle dial 9 can move to the designated position above the lens barrel. At this time, the proportional valve 18 is activated, which can control the second slider 19 to descend. The second slider 19 can be lowered through the pressure bar. The slide rail 17 slides, and the second slider 19 can drive the pressure bar body 20 to descend. At this time, the bottom end of the pressure bar body 20 can press the lens barrel with the specified pressure, thereby preventing the lens barrel from shifting position during dispensing. At the same time, the two sets of dispensing heads 14 inside the U-shaped groove 21 of the pressure bar body 20 dispense glue until it overflows and fills the entire lens. During this process, the lens barrel can be rotated by the rotating assembly table, which facilitates the dispensing heads 14 to dispense glue around the lens. After one set of lens dispensing is completed, the angle dial 9 and the pressure bar body 20 are raised by controlling the cylinder 4 and the proportional valve 18, and the moving plate 3 can be moved to the next work station by the Y-axis slide rail 2. In preparation for dispensing operations, when the angle of the dispensing head 14 needs to be adjusted, the bolts between the fixing seat 12 and the angle dial 9 can be loosened, and the fixing seat 12 can be pushed in the specified direction and angle, so that the fixing seat 12 can drive the circular slider 15 to slide inside the arc groove 10. When the dispensing head 14 on the fixing seat 12 moves to the specified angle, the bolts are tightened to fix the position of the fixing seat 12. The position of the fixing seat 12 can be adjusted according to the position of the positioning hole 11, so that the dispensing head 14 can perform dispensing operations at multiple angles. The scale value on the angle dial 9 can facilitate personnel to confirm the angle of the dispensing head 14.

[0031] See Figures 1-6 It can be seen that by using the proportional valve 18 to control the pressure, the pressure of the pressure bar body 20 can be controlled and stabilized, so that the lens can be placed stably during dispensing. In addition, the two sets of dispensing heads 14 can perform dispensing operations at multiple angles, which is suitable for dispensing operations of different lenses. At the same time, the two sets of dispensing heads 14 can improve dispensing efficiency.
