Description

Technical Field

[0001] This utility model relates to the field of dispensing device technology, specifically a miniaturized OCA optical adhesive dispensing device. Background Technology

[0002] Optical adhesive dispensing devices are key equipment for the precise application of optical adhesives. They are widely used in the packaging of optical components such as touch screens, camera modules, and LCD displays. Miniaturized OCA optical adhesive dispensing devices need to achieve high-precision dispensing in a compact structure while also taking into account portability and stability.

[0003] In the prior art, such as the liquid optical adhesive dispensing device for liquid crystal modules disclosed in CN202661757U, this utility model constructs a dam around the liquid crystal module with high viscosity adhesive. After the low viscosity adhesive flows to the edge of the high viscosity adhesive, it will flow along the edge of the dam due to resistance, which is beneficial for screen flow and reduces air bubbles and adhesive overflow.

[0004] The aforementioned device restricts the volume and shape of the adhesive by using a fixed-position dam. This results in a fixed volume and area during dispensing, limiting the device's flexibility. Simultaneously, the adhesive is pushed downwards by the cover plate, separating the LCD module, glass cover plate, and dam. Under the influence of the adhesive's surface tension, the tiny volume of adhesive tends to approach a hemispherical shape. When the cover plate moves downwards to dispense adhesive, air remains between the glass cover plate and the dam, which reduces the dispensing quality of the device. Therefore, we propose a miniaturized OCA optical adhesive dispensing device. Utility Model Content

[0005] One of the technical problems this application aims to solve is that the inability to adjust the dam restricts the flexibility of the device, and the separation of the LCD module, glass cover and dam with air trapped between them leads to a decrease in the quality of the adhesive application.

[0006] To address the aforementioned technical problems, this application provides a miniaturized OCA optical adhesive dispensing device, comprising a carrier plate, a baffle plate, and an auxiliary plate. The baffle plate is evenly distributed along the lower edge of the carrier plate, and the auxiliary plate is located in the lower middle part of the carrier plate. An adjusting member for adjusting the baffle plate is provided at the lower part of the carrier plate.

[0007] Preferably, the adjusting member includes two bolts disposed on the outer wall of the baffle, wherein a fixing plate is slidably connected to the outer periphery of the two bolts, a sliding rod is threadedly connected to the middle of the fixing plate, one end of the sliding rod near the baffle is rotatably connected to the middle of the baffle, and a pushing member for driving the adjusting member and the auxiliary plate to move is disposed on the upper part of the carrier plate.

[0008] Preferably, the pushing member includes a push block that slides on the upper part of the carrier plate, a push rod provided at the lower part of the push block, the lower end of the push rod being provided on the upper part of the auxiliary plate, a push plate provided in the middle of the fixed plate, a pull block provided at one end of the push plate near the push block, the pull block sliding on the outer wall of the push block, a driving member for driving the push block back to its original position provided on the upper part of the carrier plate, and a guide member for stabilizing the sliding of the push plate provided on the upper part of the carrier plate.

[0009] Preferably, the guide includes a plurality of guide blocks disposed at the upper edge of the carrier plate, the inner wall of the guide blocks being provided with two sliders, and the upper edge of the fixing plate having grooves on both sides, the sliders sliding inside the grooves.

[0010] Preferably, the driving component includes a driving block disposed on the upper part of the carrier plate, a spring disposed in the middle of the driving block, a telescopic rod disposed in the middle of the spring, and the lower end of the spring disposed on the upper part of the push block.

[0011] Preferably, the edge of the push block is set to be inclined.

[0012] Preferably, the lower end of the push plate is provided with a slide barrel, the baffle is provided on the side of the slide barrel away from the push plate, and two limiting plates are slidably connected inside the slide barrel, with an adjusting block provided in the middle of the limiting plate.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. By rotating the slide bar and using bolts to stabilize the sliding of the baffle, the baffle spacing can be flexibly adjusted according to the dispensing volume requirements, so as to achieve precise control of the dispensing volume and adapt to dispensing tasks of different volumes of glue.

[0015] 2. Through the linkage of components such as auxiliary plate, carrier plate, and baffle, the glue is stretched into a stable rectangle with rounded corners. At the same time, the baffle abuts against the glue dot position to effectively prevent air from mixing in, ensuring that the glue dot shape is regular and the quality is stable.

[0022] 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.

[0023] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a miniaturized OCA optical adhesive dispensing device, including a carrier plate 1, a baffle 11 and an auxiliary plate 12. The baffle 11 is evenly distributed at the lower edge of the carrier plate 1, the auxiliary plate 12 is located in the lower middle part of the carrier plate 1, and an adjusting member 2 for adjusting the baffle 11 is provided at the lower part of the carrier plate 1.

[0024] Furthermore, the adjusting component 2 includes two bolts 22 disposed on the outer wall of the baffle 11, wherein a fixing plate 21 is slidably connected to the outer periphery of the two bolts 22, and a sliding rod 23 is threadedly connected to the middle of the fixing plate 21. One end of the sliding rod 23 near the baffle 11 is rotatably connected to the middle of the baffle 11, and a pushing component 3 for driving the adjusting component 2 and the auxiliary plate 12 to move is disposed on the upper part of the carrier plate 1.

[0025] The fixing plate 21 can provide mounting support for the bolts 22 and the slide bar 23. The bolts 22 are used to balance the force on the baffle 11 and keep the baffle 11 parallel, and the slide bar 23 is used to push the baffle 11 to slide.

[0026] Furthermore, the pushing member 3 includes a push block 32 that slides on the upper part of the carrier plate 1, a push rod 34 is provided at the lower part of the push block 32, the lower end of the push rod 34 is provided on the upper part of the auxiliary plate 12, a push plate 31 is provided in the middle of the fixed plate 21, a pull block 33 is provided at the end of the push plate 31 near the push block 32, the pull block 33 slides on the outer wall of the push block 32, a driving member 5 for driving the push block 32 back to its original position is provided on the upper part of the carrier plate 1, and a guide member 4 for stabilizing the sliding of the push plate 31 is provided on the upper part of the carrier plate 1.

[0027] The push plate 31 is used to push the fixed plate 21 to move. The inclined surface of the push block 32 and the pull block 33 cooperate to push the push plate 31 to move. The push rod 34 can push the auxiliary plate 12 to rise and fall when the push plate 31 moves.

[0028] Furthermore, the guide 4 includes a plurality of guide blocks 41 disposed at the upper edge of the carrier plate 1. The inner wall of the guide block 41 is provided with two sliders 42. The upper edge of the fixing plate 21 is provided with grooves 43 on both sides, and the sliders 42 slide inside the grooves 43.

[0029] The guide block 41 provides installation space for the slider 42, which can guide the push plate 31 to slide linearly. The groove 43 provides sliding space for the slider 42.

[0030] Furthermore, the driving component 5 includes a driving block 51 disposed on the upper part of the carrier plate 1, a spring 53 disposed in the middle of the driving block 51, a telescopic rod 52 disposed in the middle of the spring 53, and the lower end of the spring 53 disposed on the upper part of the push block 32.

[0031] The drive block 51 provides mounting support for the spring 53 and the force point for the telescopic rod 52, with the spring 53 used to provide support for the telescopic rod 52.

[0032] Furthermore, the edges of push block 32 are set to be slanted.

[0033] When the device is started, adhesive is sprayed onto the auxiliary plate 12. The carrier plate 1 descends, bringing the auxiliary plate 12 closer to the dispensing position, pushing the carrier plate 1 towards the adhesive dot. The adhesive dot pushes the auxiliary plate 12 upward, which in turn pushes the push rod 34 and the push block 32 upward. The push block 32 pushes the spring 53 and the telescopic rod 52 to retract, and the push block 32 pushes the push plate 31 to slide, causing multiple fixed plates 21 to slide away. This causes the baffles 11 to slide away from each other, thus stretching and changing the shape of the adhesive. The adhesive remains relatively stable under the action of surface tension. Under the pushing of the auxiliary plate 12 and the pulling of the baffles 11, the adhesive is stretched into a stable rectangular shape with rounded corners. At the same time, the baffles 11... The contact point with the adhesive dot prevents air from getting in when the adhesive is stretched, thus enabling the device to dispensing adhesive stably. To make the adhesive adhere to the auxiliary plate 12 more stably, holes are provided on its surface to increase the adaptability of the auxiliary plate 12 to low-viscosity adhesives. For high-viscosity adhesives, the holes can be omitted. To accommodate different volumes of adhesive, when the amount of adhesive dispensed is small, the slide bar 23 can be rotated to push the baffle 11 to slide towards the center of the carrier plate 1. The bolt 22 can stabilize the sliding of the baffle 11 and balance the force on the baffle 11, thereby allowing multiple baffles 11 to move closer to each other, thereby reducing the space between multiple baffles 11 and reducing the amount of adhesive loaded between the baffles 11.

[0034] Example 2: Please refer to Figure 5Based on Embodiment 1, this utility model provides another technical solution: a slide barrel 24 is provided at the lower end of the push plate 31, a baffle 11 is provided on the side of the slide barrel 24 away from the push plate 31, and two limiting plates 26 are slidably connected inside the slide barrel 24, with an adjusting block 25 provided in the middle of the limiting plate 26.

[0035] The adjusting block 25 can slide inside the slide barrel 24. The limiting plate 26 can prevent the adjusting block 25 from slipping out of the slide barrel 24. The slide barrel 24 can fix the baffle 11. When the push plate 31 pulls the slide barrel 24 away, the slide barrel 24 can push the adjusting block 25 to slide in the current direction of movement. This allows the multiple adjusting blocks 25 to slide and expand the space between the slide barrel 24 and the adjusting block 25 when the slide barrel 24 is dispersed, thereby preventing glue from overflowing to the outside.
