Description

Technical Field

[0001] This utility model relates to the field of UV protection technology, specifically a universal UV protection dispensing device. Background Technology

[0002] In the UV protection dispensing process, the reliability of the dispensing device fixture directly affects the product's protective performance and production efficiency. Existing UV protection dispensing fixtures are designed and manufactured according to each product's drawings, which is costly and can only be applied to a single product.

[0003] For example, CN104741290A discloses an automatic UV adhesive dispensing device, including a base with a linear guide rail. A moving platform driven by a single-axis driver (driven by a servo motor) is mounted on the linear guide rail. The moving platform is equipped with a dispensing cylinder and a corresponding UV adhesive trough. A UV lamp corresponding to a product fixture is also mounted on the moving platform. This invention utilizes a single-axis driver to drive the moving platform smoothly, resulting in more uniform and faster dispensing. The high-precision positioning function of the servo motor ensures more accurate dispensing position and length. Constant-speed and uniform dispensing reduces air bubbles and improves yield. Automated dispensing replaces manual labor, keeping employees away from UV adhesive and reducing the harmful effects of its irritating odor. The dispensing process and UV light irradiation further improve work efficiency.

[0004] However, there are shortcomings: the fixture can only be designed and manufactured for a single product, which is not very flexible. When the product changes (such as size or shape adjustment), the fixture cannot be compatible and needs to be redesigned, which leads to a short life cycle and high production cost. Utility Model Content

[0005] The purpose of this utility model is to provide a universal three-proof UV dispensing device to solve the problems mentioned in the background art, which are that the fixtures can only be designed and manufactured according to a single product, which is not flexible. When the product changes (such as size or shape adjustment), the fixtures cannot be compatible and need to be redesigned, which leads to a short life cycle and high manufacturing cost.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a universal three-proof UV dispensing device, comprising a carrier frame. The carrier frame has an inner cavity with a carrier slot for placing products. An adjusting assembly is fixedly connected to the inner cavity of the carrier frame. Several adjusting assemblies are symmetrically arranged. Each adjusting assembly includes a fixing post, which is fixedly connected to the inner cavity of the carrier frame. One end of the fixing post is rotatably connected to an adjusting post. The inner cavity of the adjusting post is rotatably connected to a connecting shaft. A fixing ring is rotatably connected to the outer side of the connecting shaft. The fixing ring is fixedly connected to one end of the adjusting post. A connecting ring is rotatably connected to the outer side of the connecting shaft. One end of the connecting ring is fixedly connected to a connecting post, and one end of the connecting post is threaded with a screw.

[0008] Furthermore, the adjustment assembly also includes an elastic buffer, which is disposed between the adjustment column and the connecting shaft to absorb the impact force during the adjustment process.

[0009] Furthermore, the outer wall of the carrier frame is provided with scale markings, which correspond to the adjustment stroke of the adjustment component and are used to visually display the extension length of the adjustment column.

[0010] Furthermore, the end of the screw is provided with a rubber abutment block, and the contact surface of the rubber abutment block has an arc-shaped structure to adapt to the edge contour of the product.

[0011] Furthermore, the bottom of the carrier plate groove is provided with anti-slip texture, which is distributed in a grid pattern to increase the friction between the product and the carrier plate groove.

[0012] Furthermore, the outer side wall of the adjusting column is provided with an external thread, and the inner side wall of the fixed column is provided with an internal thread that matches the external thread. By rotating the adjusting column, its extension and retraction relative to the fixed column can be adjusted with an adjustment accuracy of 0.5 mm / turn.

[0013] Furthermore, a deep groove ball bearing is provided between the connecting shaft and the fixed ring. The outer ring of the deep groove ball bearing is fixedly connected to the fixed ring, and the inner ring is fixedly connected to the connecting shaft, so as to reduce the frictional resistance when the adjusting column rotates.

[0014] Furthermore, positioning holes are provided at the four corners of the carrier frame, which are used for pin positioning with the worktable of the dispensing equipment.

[0015] This utility model has the following beneficial effects:

[0016] I. This utility model is equipped with an adjustment component. Through the symmetrically distributed adjustment component, the fixed position in multiple directions can be adjusted synchronously according to the product size, so that one device can be adapted to products of various sizes, reducing development costs. The threaded screw provides adjustable fixing force, avoiding the defects of traditional fixtures that need to be redesigned due to changes in product shape, and improving flexibility.

[0017] II. Based on the above-mentioned beneficial effects, a carrier plate frame and a carrier plate groove are also provided. The bottom of the carrier plate groove is provided with anti-slip texture, which is distributed in a grid pattern. The anti-slip texture increases the coefficient of friction between the product and the carrier plate groove from 0.2 to over 0.5, effectively preventing product displacement caused by vibration during dispensing and ensuring that the dispensing position accuracy error is ≤0.3mm. Positioning holes are provided at the four corners of the carrier plate frame. The positioning holes are used for pin positioning with the worktable of the dispensing equipment. The positioning holes and pins can achieve rapid and accurate positioning of the device and the dispensing equipment, with a repeatability accuracy of ≤0.1mm, avoiding position deviation caused by manual placement.

[0024] 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.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-3 As shown, this utility model is a universal three-proof UV dispensing device, including a carrier frame 1. The inner cavity of the carrier frame 1 is provided with a carrier slot 2 for placing products. An adjustment component 3 is fixedly connected to the inner cavity of the carrier frame 1. Several adjustment components 3 are symmetrically arranged. The adjustment component 3 includes a fixing post 4, which is fixedly connected to the inner cavity of the carrier frame 1. One end of the fixing post 4 is rotatably connected to an adjustment post 5. The inner cavity of the adjustment post 5 is rotatably connected to a connecting shaft 6. The outer side of the connecting shaft 6 is rotatably connected to a fixing ring 7, which is fixedly connected to one end of the adjustment post 5. The outer side of the connecting shaft 6 is rotatably connected to a connecting ring 8. One end of the connecting ring 8 is fixedly connected to a connecting post 9, and one end of the connecting post 9 is threadedly connected to a screw 10.

[0027] For example, the symmetrically distributed adjustment components 3 can be used to adjust the fixed position in multiple directions simultaneously according to the product size, so that one device can be adapted to products of various sizes, reducing development costs. The threaded screws 10 provide adjustable fixing force, avoiding the defects of traditional fixtures that need to be redesigned due to changes in product shape, and improving flexibility.

[0028] The adjustment assembly 3 also includes an elastic buffer, which is disposed between the adjustment column 5 and the connecting shaft 6 to absorb the impact force during the adjustment process;

[0029] For example, when the screw 10 is tightened to fix the product, the elastic buffer can buffer the impact force generated by the rigid contact, prevent the precision electronic components from being damaged due to excessive force, solve the hidden defect of existing special fixtures that "the product is easily damaged during the fixing process", and is especially suitable for the protection of fragile samples in the research and development stage.

[0030] The outer wall of the carrier frame 1 is provided with scale markings, which correspond to the adjustment stroke of the adjustment component 3 and are used to visually display the extension length of the adjustment column 5.

[0031] For example, the scale markings allow operators to quickly locate the position of adjustment column 5 according to the product size without the need for additional measuring tools, reducing the adjustment time from 5 minutes to less than 1 minute, improving production efficiency, and is especially suitable for the rapid changeover needs of multi-batch small-volume trial production scenarios.

[0032] The end of the screw 10 is provided with a rubber abutment block, and the contact surface of the rubber abutment block has an arc-shaped structure to fit the edge contour of the product.

[0033] For example, the arc-shaped rubber clamping block replaces the rigid clamping of the traditional metal screw 10 with flexible contact, which can adapt to various product edge shapes such as circles and polygons, and avoids damaging the product surface; at the same time, the friction of the rubber material can prevent the screw 10 from loosening after fixing, and improve the fixing reliability of complex-shaped products.

[0034] The bottom of the carrier plate groove 2 is provided with anti-slip texture, which is distributed in a grid pattern to increase the friction between the product and the carrier plate groove 2.

[0035] For example, the anti-slip texture increases the coefficient of friction between the product and the carrier plate groove 2 from 0.2 to over 0.5, effectively preventing product displacement due to vibration during dispensing and ensuring that the dispensing position accuracy error is ≤0.3mm.

[0036] The outer side wall of the adjusting column 5 is provided with external threads, and the inner side wall of the fixed column 4 is provided with internal threads that match the external threads. By rotating the adjusting column 5, its extension and retraction relative to the fixed column 4 can be adjusted with an adjustment accuracy of 0.5mm / turn.

[0037] For example, the precision threaded drive structure provides quantitative adjustment accuracy, allowing operators to precisely control the extension length of the adjustment column 5 according to the product size, avoiding the rough adjustment method of traditional manual prying. It is especially suitable for precision devices with strict dimensional tolerance requirements (such as chip carriers), improving the versatility and adjustment reliability of the device.

[0038] A deep groove ball bearing is provided between the connecting shaft 6 and the fixed ring 7. The outer ring of the deep groove ball bearing is fixedly connected to the fixed ring 7, and the inner ring is fixedly connected to the connecting shaft 6 to reduce the frictional resistance when the adjusting column 5 rotates.

[0039] For example, the deep groove ball bearing converts the sliding friction of the adjusting column 5 during rotation into rolling friction, reducing the coefficient of friction from 0.15 to 0.002, making the adjustment process smoother, allowing the rotation operation to be completed with one hand, reducing operator fatigue, and extending the mechanical life of the adjusting component 3.

[0040] Positioning holes are provided at the four corners of the carrier frame 1. The positioning holes are used for pin positioning with the worktable of the dispensing equipment.

[0041] For example, the positioning hole and the pin can be used to achieve rapid and accurate positioning of the device and the dispensing equipment, with a repeatability of ≤0.1mm, avoiding positional deviations caused by manual placement.

[0042] Working principle: When in use, first loosen the fixing screw 10, place the product into the carrier plate groove 2 of the carrier plate frame 1, and adjust the product size through the symmetrically arranged adjustment components 3. The fixing column 4 and the adjustment column 5 in the adjustment components 3 are connected by threads. Rotating the adjustment column 5 can achieve a telescopic adjustment with an accuracy of 0.5mm / turn. At the same time, the deep groove ball bearing between the connecting shaft 6 and the fixing ring 7 reduces the rotational friction resistance. During adjustment, the scale markings on the outside of the carrier plate frame 1 clearly show the extension length of the adjustment column 5. After adjustment, tighten the screw 10. The rubber abutment block at the end of the screw 10 adapts to the edge of the product with an arc-shaped flexible contact surface and fixes it. The elastic buffer between the adjustment column 5 and the connecting shaft 6 absorbs the impact force during fixing. The grid-like anti-slip texture at the bottom of the carrier plate groove 2 increases the product friction and prevents displacement. Finally, the product is positioned by the positioning holes at the corners of the carrier plate frame 1 and the pins on the dispensing equipment worktable, realizing the precise fixing and quick clamping of the product in the dispensing device, and completing the three-proof UV dispensing operation of products of different sizes and shapes.

[0043] This step solves the problems of high cost, poor flexibility, and short lifespan of existing fixtures.

[0044] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
