Description

Technical Field

[0001] This utility model relates to the field of adhesive coating equipment technology, and in particular to an adhesive coating device and adhesive coating equipment. Background Technology

[0002] The adhesive is encapsulated in a container and extruded from the container outlet by squeezing or external pressure, then applied to the coating area of ​​the substrate. Currently, most adhesive outlets are circular, resulting in a cylindrical dispensing shape. During the coating process, the dispensing head needs to be moved back and forth across the product surface to expel the adhesive, distributing the cylindrical adhesive evenly across the surface. This process is repeated until the adhesive is evenly spread across the product surface. Because of the cylindrical dispensing shape, the adhesive spreading area is difficult to control, and the dispensing head needs to be moved back and forth multiple times, resulting in low coating efficiency and uneven adhesive layer thickness.

[0015] Compared with related technologies, the beneficial effects of this utility model are: The gluing device provided by this utility model involves mounting a gluing component on the frame of a gluing equipment. When gluing is required on the surface of a product, the operator first places the product to be glued on the worktable of the gluing equipment. Then, by adjusting the position of the gluing component, its outlet is brought into contact with the surface of the product to be glued.

The receiving cavity serves as a temporary storage and output channel for the glue, and its design ensures smooth glue flow. After the glue is ready, the built-in drive mechanism of the gluing equipment drives relative movement between the gluing component and the product.

[0025] Combination Figure 1 , Figure 3 As shown, an embodiment of the present invention provides an adhesive applicator, including an adhesive applicator 100.

[0026] The coating component 100 is mounted on the frame 200 of the coating equipment. The coating component 100 has a receiving cavity 110. The coating component 100 has a glue outlet 120 corresponding to the receiving cavity 110. The opening of the glue outlet 120 is downward and elongated. The coating component 100 also has a glue inlet 130 communicating with the receiving cavity 110. The glue inlet 130 is connected to the corresponding glue supply equipment through a material conveying pipe 131. The glue that enters the receiving cavity 110 through the glue inlet 130 can be output through the glue outlet 120.

[0027] The adhesive applicator provided in this embodiment mounts the adhesive applicator 100 on the frame 200 of the adhesive applicator. When adhesive application is required on the surface of a product, the operator first places the product to be coated on the worktable of the adhesive applicator. Then, by adjusting the position of the adhesive applicator 100, its outlet 120 abuts against the surface of the product to be coated. Next, the adhesive supply device connected to the adhesive applicator is started, and the adhesive supply device begins to stably deliver adhesive into the receiving cavity 110 of the adhesive applicator 100. The receiving cavity 110 serves as a temporary storage and output channel for the adhesive, and its design ensures smooth flow of the adhesive. After the adhesive is ready, the adhesive applicator 100 and the product are moved relative to each other using the built-in drive mechanism of the adhesive applicator. This relative movement can be the adhesive applicator 100 sliding on the product surface or the product moving relative to the adhesive applicator 100, depending on the actual design of the adhesive applicator. During the movement, the adhesive located in the receiving cavity 110 is evenly output from the dispensing port 120 under pressure, forming an adhesive surface with a certain width and thickness. This design not only greatly improves the adhesive application efficiency, enabling the adhesive application operation to be completed in a shorter time, but also ensures the uniformity of the adhesive thickness on the product surface.

[0028] like Figure 2 As shown, in some specific embodiments, the adhesive coating component 100 is provided with a telescopic rod 140, which passes through the frame 200. An elastic element is provided between the adhesive coating component 100 and the frame 200. The adhesive coating component 100 can telescopically move relative to the frame 200 and compress the elastic element. When the adhesive coating component 100 is subjected to an external force, it can telescopically move relative to the frame 200 and compress the elastic element in this process. The elastic element absorbs and releases energy through its own deformation.

[0029] In actual glue application, when the glue outlet 120 of the glue applicator 100 presses against the surface of the product to be glued, the glue applicator 100 will experience a certain reaction force due to slight unevenness or angular changes on the product surface. At this time, the elastic element will deform under pressure, thereby driving the glue applicator 100 to perform slight telescopic movement relative to the frame 200. This telescopic movement is actually a flexible contact method, which can automatically adjust the position and pressure of the glue applicator 100 according to the actual conditions of the product surface.

[0030] This flexible contact method not only ensures smooth glue dispensing from the glue outlet 120, avoiding uneven glue application caused by excessive distance between the glue applicator 100 and the product, but also prevents damage to the product due to excessive top pressure. Therefore, this design significantly improves the reliability and glue application quality of the glue applicator in this embodiment, enabling it to better adapt to the glue application needs of products with different shapes and materials.

[0031] In some specific embodiments, the end of the telescopic rod 140 opposite to the adhesive coating component 100 extends through the frame 200, and an adjusting nut 142 is threaded onto the protruding end of the telescopic rod 140. When it is necessary to adjust the relative position between the telescopic rod 140 and the frame 200, the operator only needs to gently turn the adjusting nut 142 to move it along the axial direction of the telescopic rod 140. This movement directly changes the extension length of the telescopic rod 140 within the frame 200, thereby adjusting the initial compression of the elastic element disposed between the adhesive coating component 100 and the frame 200.

[0032] Since the initial compression of the elastic element directly determines the initial pressure exerted by the glue outlet 120 of the coating part 100 on the surface of the product to be coated, this initial pressure can be precisely controlled by adjusting the rotation of the nut 142. This design allows the coating device to perform personalized pressure adjustments according to the material, shape, and coating requirements of different products, ensuring the stability of the coating process and the uniformity of the coating quality.

[0033] In some specific embodiments, the elastic element is a preload spring 141, which is sleeved on the telescopic rod 140. By sleeved on the telescopic rod 140, the telescopic rod 140 serves as a support structure for the preload spring 141, providing it with a stable installation position and ensuring that the preload spring 141 maintains linear extension and contraction during stress. This design of sleeved on the telescopic rod 140 effectively avoids lateral displacement of the preload spring 141 when subjected to large compressive forces.

[0034] Lateral displacement is a common failure mode of springs under stress, which can lead to a decrease in the spring's performance or even complete loss of elasticity. In this embodiment, since the preload spring 141 is securely fitted onto the telescopic rod 140, its extension and retraction direction is strictly limited, thereby ensuring that the preload spring 141 can always extend and retract along the axial direction when subjected to compressive force, avoiding failure problems caused by lateral displacement.

[0035] This design not only improves the working reliability of the elastic element, but also extends its service life, providing a strong guarantee for the long-term stable operation of the glue application device.

[0036] In some specific embodiments, the frame 200 is provided with guide posts 210 arranged parallel to the telescopic rod 140. The guide posts 210 pass through the adhesive applicator 100. This design ensures that the adhesive applicator 100 always moves along the path specified by the guide posts 210 during telescopic movement. The presence of the guide posts 210 is equivalent to providing a fixed moving track for the adhesive applicator 100, effectively limiting the offset or swaying of the adhesive applicator 100 during telescopic movement.

[0037] In actual operation, when the adhesive coating component 100 is subjected to external force and undergoes telescopic movement, the guide column 210 strictly guides its movement direction, ensuring that the adhesive coating component 100 can accurately and smoothly telescopically move along the predetermined direction. This guiding effect not only improves the reliability of the telescopic movement of the adhesive coating component 100, but also avoids problems such as uneven adhesive application or equipment damage caused by deviation in the movement direction.

[0038] In some specific embodiments, the opening direction of the glue inlet 130 is perpendicular to the opening direction of the glue outlet 120. During actual operation, when glue enters the receiving cavity 110 through the glue inlet 130, because the glue inlet 130 is perpendicular to the glue outlet 120, the glue will not flow directly towards the glue outlet 120. Instead, it will first impact the inner wall of the receiving cavity 110. This impact process actually acts as a buffer, allowing the glue to be dispersed and stabilized to a certain extent within the receiving cavity 110. After impacting the inner wall, the glue will spread evenly along the inner wall, forming a relatively stable pressure distribution within the receiving cavity 110.

[0039] This design avoids the situation where glue is directly injected from the glue inlet 130 and immediately discharged from the glue outlet 120. Direct glue discharge could lead to uneven glue pressure at the outlet 120, resulting in some areas having too much glue and others too little, thus affecting the uniformity and quality of the glue application. By aligning the glue inlet 130 and the outlet 120 perpendicularly, the design ensures a more even distribution of glue pressure from the outlet 120. Whether at the beginning or throughout the application process, the outlet 120 consistently delivers glue at a uniform pressure, resulting in a uniform glue layer thickness and a smooth surface.

[0040] In some specific embodiments, the feed pipe 131 connected to the glue inlet 130 is L-shaped. The outlet of the feed pipe 131 is connected to the glue inlet 130, and the inlet of the feed pipe 131 is connected to the corresponding glue supply device. The inlet of the feed pipe 131 is located vertically above the receiving cavity 110, ensuring the smoothness of the glue supply device in conveying glue into the receiving cavity 110, reducing the probability of glue staying in the feed pipe 131, and facilitating subsequent cleaning of the feed pipe 131.

[0041] In some specific embodiments, a gradient channel 121 is provided between the receiving cavity 110 and the dispensing port 120. The gradient channel 121 gradually widens along the long side of the dispensing port 120 and gradually narrows along the short side of the dispensing port 120 from the receiving cavity 110 to the dispensing port 120. In actual operation, when the glue flows from the receiving cavity 110 to the dispensing port 120, it passes through this gradient channel 121. Although the cross-sectional shape of the glue changes during this process, its cross-sectional area remains constant or changes only slightly due to the design of the gradient channel 121. This means that the glue's flow rate will not change drastically due to abrupt changes in cross-sectional area when passing through the gradient channel 121.

[0042] A stable glue flow rate is crucial for uniform glue application. If the flow rate is too fast, excessive glue buildup at the outlet 120 may result in an overly thick glue layer; if the flow rate is too slow, it may lead to discontinuous application or an underly thin glue layer. The gradient channel 121 design ensures a consistent glue flow rate from the receiving cavity 110 to the outlet 120. Whether in the initial stage of application or throughout the process, the outlet 120 delivers glue at a stable speed, resulting in a uniformly distributed glue layer on the product surface.

[0043] In some specific embodiments, the adhesive applicator 100 includes a main body 101 and a cover plate 102. The cover plate 102 is fixedly mounted on the main body 101 by a connector and together with the main body 101 forms the receiving cavity 110 and the adhesive outlet 120. The connector can be a common mechanical connection component such as a bolt, screw or clip. The specific choice depends on factors such as the actual use scenario, ease of assembly and the firmness of the connection.

[0044] The advantage of this split design lies in its ease of periodic disassembly and cleaning of residual adhesive. After prolonged use of the adhesive applicator, some cured or semi-cured adhesive will inevitably remain in the receiving cavity 110. If this residual adhesive is not cleaned in time, it will not only affect the effective volume of the receiving cavity 110 but may also alter the flow characteristics of the adhesive, thereby affecting the uniformity of dispensing and the quality of the coating. With the split design of the main body 101 and the cover plate 102, the operator only needs to loosen the connector and remove the cover plate 102 from the main body 101 to directly and thoroughly clean the inside of the receiving cavity 110, removing residual adhesive and impurities. After cleaning, the cover plate 102 is reinstalled onto the main body 101, ensuring a secure connection, and the adhesive applicator 100 can continue to operate normally. This design greatly improves the ease of maintenance and service life of the adhesive applicator, ensuring the stability of the coating quality.

[0045] The embodiments of this utility model also provide a glue coating device, which can be divided into automatic glue coating machines, semi-automatic glue coating machines, etc., depending on the control type. It includes the glue coating device in the above embodiments. The glue coating component 100 of the glue coating device is mounted on the frame 200 of the glue coating device.
