Description

Technical Field

[0001] This utility model relates to the field of automated production equipment technology, and in particular to a film application device. Background Technology

[0002] In the film application industry, the precision and lifespan of film application equipment are crucial factors affecting product quality. However, existing technologies still present several problems. First, current film application equipment lacks precision, and most products requiring film application are flat, making it difficult for the equipment to handle spherical surfaces effectively. Second, existing film application equipment is non-standard, with the product feeding / unloading mechanism and film application mechanism integrated rather than modular. This results in longer development times and higher costs, hindering product upgrades and equipment modifications. Furthermore, the film application mechanism uses modular movement, leading to poor overall flexibility and hindering operation and maintenance. The purpose of this application is to address these technical problems. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a film application device that, through modular design, can increase the service life of the device, reduce production costs, and improve the accuracy and effect of film application.

Detailed Implementation

[0031] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0032] like Figure 1As shown, one embodiment of this application provides a film-applying device, including a conveying assembly 3 for conveying a product 4 to be film-applied, a film-covering assembly 1 for covering the film material to be applied onto the product 4, and a film-applying assembly 2 for applying pressure to the film material to apply it onto the product 4. The conveying assembly 3 includes a conveying unit 31 for conveying the product 4 and a first drive unit for driving the conveying unit 31. The film-covering assembly 1 includes a covering unit 10 for covering the film material onto the product 4 and a second drive unit for driving the covering unit 10. The first drive unit and the second drive unit independently provide power to the conveying unit 31 and the covering unit 10, respectively, so that the transport line is separated from the film-covering and film-applying modules. This can reduce the development cost and cycle of the film-applying device and improve the reusability of the modular structure after the product 4 is modified.

[0033] like Figure 2 As shown, the film coating assembly 1 is used to coat the uncoated product 4 with film, and also includes a frame 11, a film supply unit 12, a monitoring unit 13, and a transport unit 14. The film supply unit 12 is used to provide film material to the coating unit and can realize automatic film supply and peeling. The monitoring unit 13 is used to detect the relative position of the film material and the product 4. The transport unit 14 is used to remove the film material from the film supply unit 12 and adjust the position of the monitoring unit 13 so that the monitoring unit 12 can take pictures of the film material and the product 4. Furthermore, the film supply unit 12, the monitoring unit 13, and the transport unit 14 are all mounted on the frame 11.

[0034] like Figure 3 As shown, the transport unit 14 includes a main body 1410 rotatably mounted on a frame 11, a first connecting shaft 1411 vertically mounted on the main body 1410, a second connecting shaft 1412 telescopically connected to the first connecting shaft 1411, and a rotating shaft 1413 rotatably mounted on one end of the second connecting shaft 1412. The transport unit 14 also includes a base 143 for connecting to the frame 11 and a vacuum generator 144 disposed on the side of the base. The base 143 is disposed at the bottom of the main body 1410, and the main body 1410 is fixed to the frame 11 via the base 143. The vacuum generator 144 communicates with the suction member 101, so the suction member 101 uses vacuum suction to pick up the membrane. In a further embodiment, the transport unit 14 is preferably a four-axis robot. The suction unit 101 and the second camera assembly 132 are both connected to the rotating shaft 1413. The rotation and extension of the four-axis robot enable the suction unit 101 to accurately complete the film taking and coating process, and also enable the second camera assembly 132 to take pictures of the product 4 at the accurate position.

[0035] like Figure 4 A to Figure 4As shown in Figure B, the covering unit 10 includes a suction member 101, which is used to suction the film material. The suction member 101 is mounted on the rotating shaft 1413 and is positioned facing the product 4. The covering unit 10 also includes a spring 102, a spring pin 103, and a connecting plate 104. The connecting plate 104 is used to connect the suction member 101 to the rotating shaft 1413. The spring 102 is disposed between the connecting plate 104 and the suction member 101 to ensure that the suction member 101 adheres to the surface of the product 4 when taking and applying the film. The spring pin 103 is disposed on one side of the suction member 101, and its length is greater than the thickness of the suction member 101, so that the spring pin 103 can press down on the product 4 when the suction member 101 applies the film, preventing the product 4 from being lifted up after the film is applied.

[0036] like Figures 5 to 6 As shown, the monitoring unit 13 includes a first camera assembly 131 and a second camera assembly 132. The first camera unit 131 is used to take pictures of the film material to confirm the position of the film material being absorbed, and is mounted on the frame 11. The first camera assembly 131 includes a first lens unit, a first supplementary light source 1312, a first image sensor 1311, and a fixing bracket 1313. The fixing bracket 1313 is used to fix the first lens unit and the first supplementary light source 1312. The first supplementary light source 1312 provides supplementary light for the first lens unit to take pictures. The first image sensor 1311 is used to transmit the film material picture to the processor. The first image processor 1311 also includes a protective cover 13110, which is used to protect the first image processor 1311 and the first lens unit. The first image processor 1311 and the first lens unit are housed in the protective cover 13110 and embedded in the frame 11.

[0037] like Figure 6 As shown, the second camera unit 132 is used to take pictures of product 4 to confirm the position of product 4 to be coated, and is connected to the transport unit 14. The second camera unit 132 includes a second lens unit, a second image sensor 1321, a second supplementary light source 1322, and a connecting bracket 1323. The connecting bracket 1323 is used to fix the second lens unit, the second image sensor 1321, and the second supplementary light source 1322 on the rotation axis 1413 of the transport unit 14. The second lens unit and the second image sensor 1321 are both disposed above the second supplementary light source 1322. The second supplementary light source 1322 provides supplementary light for the second lens unit to take pictures. The second image sensor 1321 is used to transmit the picture of product 4 with film to the processor. The first camera unit 131 and the second camera unit 132 are electrically connected to the processor respectively. After the two transmit the pictures they have taken to the processor, the processor overlaps and compares the position of the film material with the position of product 4 to ensure that the film material can be applied to the accurate position of product 4, which greatly improves the accuracy of the coating position. In a further embodiment, the first camera assembly 131 and the second camera assembly 132 are preferably CCD cameras.

[0038] The laminating assembly 1 applies the film material to the surface of product 4. However, since product 4 is preferably spherical, the film material cannot be completely adhered to the surface of product 4. Therefore, an additional laminating assembly 2 is needed to imprint the film material onto the entire surface of the spherical product 4. Figure 7 As shown, the film-applying assembly 2 is used to apply pressure to the film material to apply it onto the product 4. The film-applying assembly 2 is fixed above the conveying unit 31 and faces the product 4. The film-applying assembly 2 includes an imprinting element 21, a cylinder 22, and a mounting plate 23. The imprinting element 21 is used to press the film material onto the product 4. The cylinder 22 is used to drive the imprinting element 21, that is, to provide pressure for the imprinting process. The mounting plate 23 is used to mount the imprinting element 21 and is connected to the cylinder 22 in a transmission manner. The film-applying assembly 2 also includes a fixing element 24 and an elastic element 25. The fixing element 24 is used to fix the cylinder 22 and the mounting plate 23 to other robotic arms, and the fixing element 24 is located above the cylinder 22. The elastic element 25 is used to press down the product 4 to prevent the product 4 from being lifted up after pressing. In a further embodiment, the embossing component is preferably made of soft rubber. The embossing component 21 uses soft rubber to press the film material onto the surface of the product 4, which increases the adhesion between the film material and the product 4 and realizes the spherical film application process.

[0039] like Figure 8 As shown, the conveying assembly 3 is used to convey the product 4 to be laminated, and includes a conveying unit 31 and a fixture 32. The conveying unit 31 is used to convey the fixture 32, and includes a conveyor belt 311, which includes an upper belt and a lower belt, which operate independently. The conveyor belt 311 also includes a blocking device and a limiting device, which are used to restrict the fixture 32 and prevent it from moving during the lamination process. Figure 9 As shown, fixture 32 is used to carry product 4 and is placed on conveyor belt 311. It includes a main body plate 321 and a positioning pin 322. The positioning pin 322 and product 4 are both located on the same side of the main body plate 321. The positioning pin 322 is used to further limit the position of the main body plate 321. The main body plate 321 is also provided with a reserved position 323. In a further embodiment, the reserved position 323 can be used to install product 4, providing the possibility of adding modules later. Product 4 on fixture 32 is conveyed to film coating assembly 1 by conveyor belt 311 for film coating. After film coating, it is conveyed to film application assembly 2 for pressing to complete the automatic film application process.

[0040] Based on the above-mentioned film application equipment structure, the specific process of automatic film application for product 4 is as follows: The operator feeds the film material to the film supply unit 12, and the film supply unit 12 automatically supplies and peels off the film; at the same time, the operator places product 4 on the fixture 32 and presses the release button; the conveying component 3 starts, and the conveyor belt 311 of the conveying unit 31 conveys the fixture 32 to the film application component 1. The blocking device and the limiting device of the conveying unit 31 operate in sequence, automatically blocking and limiting the fixture 32 to prevent the fixture 32 from shifting during the film application process. Meanwhile, the conveying unit 14 of the laminating assembly 1 starts operating. The conveying unit 14 rotates to the film supply unit 12, and the suction member 101 of the laminating unit 10 picks up the film material. After picking up the film, the conveying unit 14 rotates to the first camera assembly 131, which takes a picture of the film material and uploads the image to the processor. The conveying unit 14 then rotates back to the product 4 on the fixture 32. At this time, the second camera assembly 132 fixed on the conveying unit 14 takes a picture of the product 4 and uploads the image to the processor. The processor compares the two pictures and determines the accurate position for lamination. Then, the suction member 101 applies the film material to the surface of the product 4. The same operation is performed on other products 4 on the fixture 32. After the lamination process is completed, the limiting device and the blocking mechanism retract sequentially, and the conveyor belt 311 continues to transport the fixture 32 to the lamination assembly 2. Upon reaching the lamination assembly 2, the blocking device and the limiting device rise again to limit the fixture 32, and the imprinting element 21 of the lamination assembly 2 moves, applying downward pressure to completely adhere the film material to the surface of the product 4. After completion, the imprinting element 21 retracts, completing the lamination process. Finally, the blocking device and the limiting device retract again, and the automatic lamination process of the product 4 is completed.

[0041] In the automatic film application process, product 4 undergoes two processes: lamination and film application. The film material is stably pressed onto the surface of product 4, which not only achieves automatic film application for spherical products but also improves the quality of product 4. Furthermore, the first camera assembly 131 and the second camera assembly 132 are preferably CCD cameras. The CCD cameras take pictures of the film material and the product successively, and the film is applied after comparison, which improves the positional accuracy of film application and further improves the quality of product 4. In addition, the handling unit 14 is preferably a four-axis robot, which realizes the flexibility of the film application equipment by handling the film material.

[0042] In summary, the film-applying device provided by the above embodiments of this utility model includes a conveying component 3, a film-coating component 1, and a film-applying component 2. The conveying component 3 includes a conveying unit 31 and a fixture 32. The film-coating component 1 includes a frame 11, a film-coating unit 10, a film-supplying unit 12, a monitoring unit 13, and a transport unit 14. The film-applying component includes an imprinting element 21. The conveying unit 31 conveys the fixture 32 sequentially to the film-coating component 1 and the film-applying component 2. During the film-coating process, the monitoring unit 13 uses a CCD camera to photograph the film material and the product 4. After comparison, the film is applied, improving the accuracy of the film-coating position on the product 4 and improving the quality of the product 4. After film-coating, the imprinting element 21 of the film-applying component 2 presses the film material onto the surface of the product 4, achieving a bonding effect on the spherical surface of the product 4 and further improving the quality of the product 4. In addition, the conveying component 3 also includes a first driving unit, and the film coating component 1 also includes a second driving unit. The first driving unit and the second driving unit operate independently, that is, the conveying component 3 and the film coating component 1 operate independently. This design realizes a modular mechanism that separates the film application from the product 4 transmission line, which can reduce the development cost and cycle of the modular mechanism, and also improve the reusability of the modular mechanism after the product 4 is modified.

[0043] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
