Therefore, the first component, region, layer, and / or part discussed below may be referred to as the second component, region, layer, and / or part without departing from some embodiments of this utility model.

[0025] In order to overcome the above-mentioned defects in the prior art, the present invention provides an automatic adhesive bonding device for products.

[0026] Figures 1 to 5 This is a schematic diagram of the automatic adhesive bonding device from different viewing angles, according to an embodiment of the present invention. The automatic adhesive bonding device provided by the present invention will be described in detail below with reference to the drawings.

[0027] Please refer to Figure 1 The automatic adhesive bonding equipment 100 provided by this utility model includes: an adhesive transfer mechanism 101 for adsorbing adhesive and transferring it between multiple preset workstations; a release paper removal mechanism 102 for removing the release paper from the adhesive; a product conveyor belt 103 for conveying products to be bonded with adhesive, the product conveyor belt 103 being provided with an adhesive holder 104 for placing the adhesive with the release paper removed, the adhesive surface of the adhesive with the release paper removed facing the adhesive holder 104 and the front end extending out of the adhesive holder 104; and a bonding mechanism 105.

[0028] You can refer to the following: Figure 2 ,like Figure 2 As shown, the bonding mechanism includes a pre-press head 201 and a pressing roller 202. The pre-press head 201 and the pressing roller 202 are sequentially arranged in front of the adhesive backing frame 204 on the product conveyor belt 203. When the product (not shown) is conveyed by the product conveyor belt 203 to a preset position below the adhesive backing frame 204, the pre-press head 201 presses down to adhere the front end of the adhesive backing 205 to the product. As the product conveyor belt 203 is conveyed forward, the adhesive backing 205 on the adhesive backing frame 204 falls onto the product and is conveyed to the pressing roller 202 along with the product. The pressing roller 202 rolls to adhere the adhesive backing 205 to the product.

[0029] Please continue to refer to this. Figure 2 In a preferred embodiment of the present invention, the adhesive backing frame 204 includes side plates 206 fixed at predetermined positions on both sides of the product conveyor belt 204, multiple crossbars 207 connecting the two side plates 206, and adhesive backing limiting plates 208 disposed on the two side plates. The adhesive backing limiting plates 208 limit the adhesive backing of the product after the release paper has been removed to the middle position of the adhesive backing frame 204. An anti-stick roller 209 is rotatably mounted on the crossbars 207. When the adhesive backing 205 is conveyed forward with the product, it drives the anti-stick roller 209 to roll forward.

[0030] It should be noted that the device structure of the adhesive backing holder described here is merely illustrative, intended to clearly illustrate the adhesive bonding process of the automatic adhesive bonding equipment provided by this utility model. Other similar device structures that can temporarily store the adhesive backing of the removed release paper can also be applied to the automatic adhesive bonding equipment provided by this utility model, and should all be included within the protection scope of this utility model.

[0031] Understandably, since the bonding equipment provided by this utility model in the illustrated embodiment processes strip-shaped products and adhesive backing, the strip structure, due to its certain length, cannot ensure that the long strip of adhesive backing is instantly and accurately pasted to the back of the product and adhered properly in all places. Therefore, it is necessary to set up an adhesive backing rack to temporarily store the adhesive backing with the release paper removed. As the product conveyor belt moves forward, the long strip of adhesive backing is gradually placed on the product surface, and then the bonding rollers behind the product conveyor belt roll and press to achieve the bonding of the strip-shaped adhesive backing.

[0032] In a preferred embodiment, the pressure of the clamping roller is not less than 2 kg. It is understood that the pressure provided by the clamping roller can affect the strength and quality of the adhesive bonding, therefore, it is necessary to select a clamping roller with an appropriate pressure according to the product requirements. Furthermore, the pressure setting of the clamping roller can be adjusted according to the material of the product to be processed.

[0033] Preferably, the automatic adhesive bonding equipment provided by this utility model also includes an adhesive hopper, please refer to [reference needed]. Figure 3 The adhesive hopper includes a storage rack 301 for storing adhesive and an adhesive conveyor belt 302. The storage rack 301 is equipped with an adhesive lifting mechanism 303, which is used to lift the adhesive stored in the storage rack 301 to the top of the storage rack 301. The adhesive transfer mechanism 304 transfers the adhesive lifted to the top of the storage rack 301 to the adhesive conveyor belt 302 for further processing.

[0034] Furthermore, in a preferred embodiment of the present invention, the automatic adhesive bonding device provided by the present invention further includes an adhesive positioning mechanism for calibrating and positioning the bonding angle of the adhesive before transferring it to the adhesive holder.

[0035] You can refer to the following: Figure 4In this embodiment, the adhesive positioning mechanism includes a positioning plate 401, on which a plurality of positioning protrusions 402 are provided around the outer contour of the standard position of the adhesive. The adhesive transfer mechanism 403 transfers the adhesive 404 onto the positioning plate 401, and the adhesive 404 falls into the position defined by the plurality of positioning protrusions 402 to complete the positioning.

[0036] Similarly, the specific device structure of the positioning plate described herein is merely illustrative, intended to clearly illustrate how the automatic adhesive bonding device provided by this utility model ensures the consistency of the adhesive bonding position angle during the adhesive bonding process, and is not intended to limit the scope of protection of this utility model. Other similar device structures that can position and calibrate the adhesive placement angle can be applied to the automatic adhesive bonding device provided by this utility model, and should also be included within the scope of protection of this utility model.

[0037] In one embodiment, such as Figure 4 As shown, the release paper removal mechanism includes a clamp 405 for holding the release paper label and a drive member 406 for driving the clamp 405 to move. In this utility model, the release paper with adhesive backing has a label protruding from the adhesive backing end. After the clamp 405 holds the release paper label, the drive member 406 drives the clamp 405 to move to tear off the release paper with adhesive backing.

[0038] More preferably, in one embodiment, please refer to Figure 4 The release paper removal mechanism is positioned close to the adhesive positioning mechanism to remove the release paper of the adhesive after calibration and positioning.

[0039] It is easy to understand that if the adhesive release paper is removed before positioning, the adhesive will stick to the positioning plate 401, causing inconvenience to subsequent processing. Therefore, the adhesive release paper needs to be removed after the positioning work is completed. Thus, the release paper removal mechanism is set near the positioning mechanism, which reflects the rationality of the process design.

[0040] Please continue to refer to this. Figure 3 In a preferred embodiment of this utility model, the adhesive conveyor belt 302, the adhesive positioning mechanism 305, and the product conveyor belt 306 are arranged in parallel, and the adhesive positioning mechanism 305 and the adhesive holder 307 are located at the same position in the conveying direction of the product conveyor belt 306 (the direction of the arrow in the figure), and the conveying range of the adhesive conveyor belt 302 includes this position. In other words, along the direction of the arrow in the figure, the adhesive positioning mechanism 305, the adhesive holder 307, and the adhesive conveyor belt 302 can be side by side, thereby facilitating the transfer of adhesive among the three by the adhesive transfer mechanism.

[0041] Furthermore, such as Figure 3As shown, the adhesive transfer mechanism includes a first gantry 308, which spans and is perpendicular to the adhesive conveyor belt 302, the adhesive positioning mechanism 305, and the product conveyor belt 306. A first adhesive transfer component 309 is provided on the first gantry 308, which transfers adhesive between the adhesive conveyor belt 302, the adhesive positioning mechanism 305, and the adhesive frame 307 along the top beam direction of the first gantry 308.

[0042] Even better, such as Figure 3 As shown, the distances between the adhesive conveyor belt 302 and the adhesive positioning mechanism 305, and between the adhesive positioning mechanism 305 and the product conveyor belt 306, are equal and have a value of L. The first adhesive transfer member 309 is provided with two adhesive transfer plates 310 and 311 that are parallel in position and have a spacing of L. The lifting of the two adhesive transfer plates 310 and 311 is independently controlled.

[0043] As can be seen, the arrangement of the two adhesive transfer plates 310 and 311 on the first gantry 308 and the first adhesive transfer component 309 allows for the simultaneous synchronous transfer of multiple adhesive sheets from the adhesive conveyor belt 302 to the adhesive positioning mechanism 305 and from the adhesive positioning mechanism 305 to the adhesive rack 307. This ingenious device structure design improves the automation efficiency of adhesive application and processing. The specific structure of the gantry and adhesive transfer mechanism described here is merely illustrative, intended to provide a preferred embodiment illustrating the preferred device structure of the automatic adhesive bonding equipment provided by this utility model, and is not intended to limit the scope of protection of this utility model. Other similar structural designs that can achieve synchronous and parallel multi-process adhesive processing to improve work efficiency can also be applied to the automatic adhesive bonding equipment provided by this utility model and should all be included within the scope of protection of this utility model.

[0044] Please continue to refer to this. Figure 3 In one embodiment, in the automatic adhesive bonding equipment provided by this utility model, the rack 301 is arranged parallel to the adhesive conveyor belt 302, and the adhesive conveyor belt 302 covers the location of the rack 301 in a direction perpendicular to the direction in which it conveys adhesive. The adhesive transfer mechanism also includes a second gantry 312, on which a second adhesive transfer member 313 is provided. The second adhesive transfer member 313 is provided with an adhesive transfer plate 314 that can be lifted and lowered. The second adhesive transfer member 313 drives the adhesive transfer plate 314 to move perpendicular to the direction of the adhesive conveyor belt 302 to transfer adhesive between the rack 301 and the adhesive conveyor belt 302.

[0045] For example, in Figure 3In the illustrated embodiment, the adhesive conveyor belt 302 consists of two connected tracks. One section is flush with the rack 301, and the second adhesive transfer member 313 transfers the adhesive from the rack 301 to the adhesive conveyor belt 302. The adhesive conveyor belt 302 then conveys the adhesive forward. Furthermore, the other section of the adhesive conveyor belt 302 is flush with the adhesive positioning mechanism 305, and the first adhesive transfer member 309 transfers the adhesive from the adhesive conveyor belt 302 to the adhesive positioning mechanism 305.

[0046] More preferably, in one embodiment, the adhesive hopper includes a plurality of hopper racks arranged side by side, such as Figure 3 As shown, the racks 301 and 315 are arranged side by side, allowing for the storage of more adhesive material. The second adhesive transfer member 313 moves along the top beam of the second gantry 312 to obtain the adhesive from the multiple racks, and then transfers the adhesive onto the adhesive conveyor belt 302.

[0047] In other words, the movement of the second adhesive transfer member 313 can cover the plurality of racks, thereby transferring the adhesive in the plurality of racks onto the adhesive conveyor belt 302.

[0048] The quantity, form, and location of the adhesive trays described herein are merely illustrative examples, intended to provide preferred embodiments and illustrate the device structure of the automatic adhesive bonding equipment provided by this utility model, and are not intended to limit the scope of protection of this utility model. In practice, the specific settings of the adhesive trays can be adjusted according to the actual working conditions and usage requirements, and similar structures should all be included within the scope of protection of this utility model.

[0049] Please refer to the reference. Figure 5 In a preferred embodiment, the automatic adhesive bonding equipment provided by this invention includes a sensor 502 at the end of the product conveyor belt 501 for detecting whether the product has adhesive backing. The equipment alarms when it detects that the conveyed product lacks adhesive backing. The sensor effectively reduces the occurrence of adhesive backing leakage, improving equipment reliability and production yield.

[0050] In one embodiment, reference may be made to Figure 1 The automatic adhesive bonding equipment 100 provided by this utility model also includes a product flipping mechanism 106, which is located at the starting point of the product conveyor belt 103 and is used to flip the product onto the product conveyor belt so that the back of the product faces upward for adhesive bonding.

[0051] The automatic adhesive bonding equipment provided by this utility model can reduce adhesive leakage, improve product processing perfection, reduce manual operation, and lower labor costs. At the same time, the automated bonding process can improve the consistency of adhesive bonding and improve product quality.

[0052] The preceding description is provided to enable any person skilled in the art to practice the various aspects described herein. However, it should be understood that the scope of protection of this utility model should be determined by the appended claims and should not be limited to the specific structures and components of the embodiments described above. Those skilled in the art can make various changes and modifications to the embodiments, and these changes and modifications also fall within the scope of protection of this utility model.
