Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, and in particular to a double-sided adhesive applicator. Background Technology

[0002] As is well known, a double-sided tape applicator refers to an automated process for applying adhesive to semi-finished products. It involves applying double-sided tape (3M tape) one by one to the adhesive surface of the product. Based on the equipment program settings, it can realize fully automated processes such as material feeding, adhesive separation, adhesive application, cutting, and material collection, which can greatly reduce labor costs and make the tedious adhesive application work efficiently completed under the operation of the double-sided tape applicator.

[0003] Currently, existing double-sided tape applicators require precise tape application, necessitating monitoring. Conventional monitoring relies on two cameras to scan the top and bottom surfaces, confirming the position of the adhesive side and the presence of the product. While this dual-camera system achieves top-and-bottom detection, both cameras must be positioned directly above and below the product. This limits the structural layout of other components and increases costs. Utility Model Content

[0004] To address the shortcomings of the existing technology, the purpose of this utility model is to provide a double-sided adhesive applicator that uses a single camera to detect both the top and bottom surfaces.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A double-sided tape applicator includes a main body and a feeding mechanism, a dispensing mechanism, a applying mechanism, a cutting mechanism, and a receiving mechanism mounted on the main body. A vertical plate is set between the discharge port of the feeding mechanism and the dispensing mechanism. A camera is mounted on the side of the main body on the vertical plate. Two symmetrically arranged detection blocks are set on one end face of the vertical plate via a crossbar. A material feeding space is formed between the two detection blocks. A right-angle prism is embedded in each detection block. One end face of the two right-angle prisms faces one point of the material feeding space, and the other end face of the right-angle prisms faces the camera. An avoidance hole is provided on the vertical plate directly opposite the detection port of the camera.

[0007] Preferably, the feeding mechanism includes a material reel storing products, a double-sided adhesive reel storing double-sided adhesive, and a waste reel for winding up the double-sided adhesive release film. The material reel guides the products to the feeding space via a roller assembly and places them in the adhesive application mechanism through the feeding space. The double-sided adhesive reel guides the double-sided adhesive to the adhesive separation mechanism via a roller assembly. The waste reel receives the double-sided adhesive release film separated by the adhesive separation mechanism via a roller assembly.

[0008] Preferably, the adhesive separating mechanism includes a first substrate and an adhesive separating plate. The first substrate is fixedly mounted on the main body. One end of the first substrate receives double-sided adhesive introduced by the double-sided adhesive reel via a roller assembly. The adhesive separating plate is fixedly mounted on the other end of the first substrate, and the top end of the adhesive separating plate is suspended. The upper surface of the top end of the adhesive separating plate is a horizontal plane, and the lower surface of the top end of the adhesive separating plate is an inclined plane. A pressure plate is provided on the adhesive separating plate at the inclined plane, and a feed port for the double-sided adhesive release film to pass through is provided between the pressure plate and the inclined plane.

[0009] Preferably, the adhesive applicator includes two second substrates vertically mounted on the main body, with a pressure roller shaft and a support roller shaft disposed between the second substrates. The support roller shaft is connected to the product introduced by the material reel and the double-sided adhesive separated by the adhesive separating plate. A first cylinder is disposed on the second substrate, and the first cylinder is connected to the pressure roller shaft via a hinge rod. The push rod of the first cylinder is hinged to one end of the hinge rod, and the pressure roller shaft is connected to the other end of the hinge rod. By pushing the first cylinder, the pressure roller shaft is pressed against the support roller shaft.

[0010] Preferably, the cutting mechanism includes a blade for cutting double-sided tape and a linear module for driving the blade to move laterally and repeatedly. The blade is fixedly mounted on the movable seat of the linear module, and the cutting edge of the blade extends to the support roller shaft.

[0011] Preferably, the receiving mechanism includes a receiving reel for winding the product, and the receiving reel receives the product discharged by the adhesive applicator via a roller assembly.

[0012] By adopting the above solution, this utility model uses two opposing right-angle prisms to optically refract the upper and lower surfaces of the product, allowing the images of the upper and lower surfaces of the product to be uniformly imported into the same camera. Thus, the design requirements can be met with a single camera, and the camera does not need to be vertically installed on the upper and lower surfaces of the product, freeing up more space for other mechanisms to be laid out.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a mechanical connection or an electrical connection.

[0021] like Figures 1 to 5As shown, this embodiment provides a double-sided tape applicator, including a main body 1 and a feeding mechanism 2, a dispensing mechanism 3, an applicating mechanism 4, a cutting mechanism 5, and a receiving mechanism 6 mounted on the main body 1. A vertical plate 11 is set between the discharge port of the feeding mechanism 2 and the dispensing mechanism 3. A camera 12 is mounted on the side of the main body 1 on the vertical plate 11. Two symmetrically arranged detection blocks 14 are set on one end face of the vertical plate 11 via a crossbar 13. A material feeding space 15 is formed between the two detection blocks 14. A right-angle prism 16 is embedded in each detection block 14. One end face of the two right-angle prisms 16 faces one point of the material feeding space 15, and the other end face of the right-angle prisms 16 faces the camera 12. An avoidance hole 17 is provided on the vertical plate 11 directly opposite the detection port of the camera 12.

[0022] This embodiment mainly uses two opposing right-angle prisms 16 to optically refract the upper and lower surfaces of the product, so that the images of the upper and lower surfaces of the product are uniformly imported into the same camera 12. Thus, the design requirements can be met by relying on a single camera 12, and the camera 12 does not need to be vertically set on the upper and lower surfaces of the product, which can free up more space for other mechanisms to carry out structural layout.

[0023] It should be noted that the product in this embodiment is a strip-shaped product, such as some labels. That is, double-sided tape is applied to the adhesive parts of these products. Specifically, when the product passes through the material feeding space 15, that is, between the detection blocks 14, the right-angle prism 16 embedded in the detection block 14 can, according to the optical principle of the right-angle prism 16, export the image of one side from the other side. Based on this principle, the images of the upper and lower surfaces of the product can be successfully guided to the side. The side then enters the camera 12 through the setting of the avoidance hole 17. A single camera 12 can successfully capture the upper and lower surfaces of the product.

[0024] The overall adhesive application process for the product is specifically completed by the feeding mechanism 2, the adhesive dispensing mechanism 3, the adhesive application mechanism 4, the cutting mechanism 5, and the receiving mechanism 6. The specific structures of these mechanisms are as follows:

[0025] The feeding mechanism 2 in this embodiment includes a material reel 21 storing products, a double-sided adhesive reel 22 storing double-sided adhesive, and a waste reel 23 for winding up the double-sided adhesive release film. The material reel guides the products to the feeding space 15 through the roller assembly 100 and places them in the adhesive application mechanism 4 through the feeding space 15. The double-sided adhesive reel 22 guides the double-sided adhesive to the adhesive separation mechanism 3 through the roller assembly 100. The waste reel 23 receives the double-sided adhesive release film separated by the adhesive separation mechanism 3 through the roller assembly 100.

[0026] The adhesive separating mechanism 3 in this embodiment includes a first substrate 31 and an adhesive separating plate 32. The first substrate 31 is fixedly mounted on the main body 1. One end of the first substrate 31 receives double-sided adhesive introduced by the double-sided adhesive reel 22 through a roller assembly 100. The adhesive separating plate 32 is fixedly mounted on the other end of the first substrate 31, and the top end of the adhesive separating plate 32 is suspended. The upper surface of the top end of the adhesive separating plate 32 is a horizontal plane, and the lower surface of the top end of the adhesive separating plate 32 is an inclined plane. A pressure plate 33 is provided at the inclined plane of the adhesive separating plate 32, and a feed port 34 for the double-sided adhesive release film to pass through is provided between the pressure plate 33 and the inclined plane. The adhesive separating operation refers to the separation of the release film of the double-sided adhesive (3M adhesive). First, it needs to be manually separated, and after the release film is separated, it is wound into the waste reel 23. Furthermore, since the double-sided adhesive passes through the adhesive separating plate 32, during subsequent feeding, only the release film is fixed and pulled. After the release film bends from the top of the adhesive separating plate 32 and passes through the feed port 34, it will naturally peel off the release film by relying on the top of the cone-shaped adhesive separating plate 32. The peeled double-sided adhesive will continue to be pushed forward and sent into the adhesive applicator 4.

[0027] The adhesive applicator 4 in this embodiment includes two second substrates 41 vertically mounted on the main body 1. A pressure roller shaft 43 and a support roller shaft 42 are disposed between the second substrates 41. The support roller shaft 42 receives the product introduced by the material reel 21 and the double-sided adhesive separated by the adhesive separating plate 32. A first cylinder 44 is provided on the second substrate 41. The first cylinder 44 is connected to the pressure roller shaft 43 through a hinge rod 45. The push rod of the first cylinder 44 is hinged to one end of the hinge rod 45, and the pressure roller shaft 43 is connected to the other end of the hinge rod 45. By pushing the first cylinder 44, the pressure roller shaft 43 is pressed against the support roller shaft 42. When the double-sided adhesive (which is not too long, usually a few centimeters, so it can be pushed along the set direction without traction) and the part of the product to be adhered to reach the pressure roller 43 at the same time, the first cylinder 44 is driven to press the support roller 42 onto the double-sided adhesive from top to bottom, so that the double-sided adhesive is adhered to the product. After the adhesion is completed, wait for the double-sided adhesive to be cut. Note that it is not the product that is cut.

[0028] As for the cutting mechanism 5, in this embodiment, the cutting mechanism 5 includes a blade 51 for cutting double-sided adhesive and a linear module 52 for driving the blade 51 to move laterally and repeatedly. The blade 51 is fixedly installed on the movable seat of the linear module 52, and the cutting edge of the blade 51 extends to the support roller shaft 42. After the adhesive is applied, the linear module 52 is run so that the blade 51 slices through the double-sided adhesive, thereby cutting it. Of course, when it enters the receiving mechanism 6, a pressure roller shaft 101 can also be set up to apply pressure to the double-sided adhesive and the product again to ensure a stable bond.

[0029] After the adhesive is applied, the product is wound up. Therefore, the winding mechanism 6 in this embodiment includes a winding reel 61 for winding the product. The winding reel 61 receives the product discharged from the adhesive application mechanism 4 through a roller assembly.

[0030] Furthermore, it should be noted that the reels in this embodiment can all be equipped with turntables that have their own motors for rotation, and these roller groups can be equipped with motors or cylinders as needed for auxiliary operation. Moreover, the entire mechanism can be assembled in a modular form, which facilitates later replacement and maintenance.

[0031] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
