[0032] The present application provides a film sticking device, such as Figures 1 to 9 As shown, it includes a base 10, a carrying component 20 and an attaching component 30. The carrying component 20 is slidably installed on the base 10 along a first direction. The carrying component 20 is used to carry and fix the product to be film-attached;

[0033] The attachment assembly 30 includes an attachment plate 31, a pressure roller 32 and a first negative pressure member. The attachment plate 31 includes a fixed end 311 and a movable end 312. The fixed end 311 is hingedly connected to the base 10 through a hinge shaft 35, and the movable end 312 extends toward a side away from the bearing assembly 20. The pressure roller 32 is rollably arranged at the movable end 312. The attachment plate 31 is also provided with a first air hole 310. The first negative pressure member is connected to the first air hole 310. The first negative pressure member is used to generate negative pressure at the first air hole 310 to adsorb the protective film. The pressure roller 32 is used to press the protective film to make it adhere to the product to be filmed.

[0034] When the movable end 312 abuts against the product to be film-coated, the plane where the attachment plate 31 is located is parallel to or intersects with the plane where the product to be film-coated is located.

[0035] like Figures 1 to 3 As shown, the present application uses the attachment plate 31 of the attachment component 30 and the first negative pressure member to adsorb and fix the protective film, and then in the process of film pasting, by pulling the bearing component 20 to make the pressure roller 32 roll on the product to be pasted, and disconnecting the exhaust of the first negative pressure member, the protective film originally adsorbed and fixed on the attachment plate 31 can be attached to the product to be pasted; wherein when the plane where the entire attachment plate 31 is located is parallel to the product to be pasted, then it is necessary to apply a certain pressure to the attachment plate 31 externally to compress the protective film to achieve attachment, and it is also possible to allow only the active end 312 to abut against the product to be pasted, so that the weight of the attachment plate 31 itself can be converted into pressure and applied to the product to be pasted from the pressure roller 32, thereby compressing the protective film for easy attachment; the film pasting device provided by the present application can effectively improve the production conversion rhythm, specifically up to 3min / time, which is 90% higher than the production rhythm of the traditional film pasting device; the disassembly and assembly rhythm is increased to 5min / time, which is 95% higher than that of the traditional film pasting device, and only pneumatic attachment is required, without the need for electrical connection.

[0036] In application, the carrying assembly 20 can be raised and lowered in the third direction to adjust the height of the product to be film-coated carried and fixed by the carrying assembly 20, so as to facilitate adaptation with the attaching assembly 30. Specifically, the height of the product to be film-coated is lower than the height of the attaching assembly 30. In one case, Figure 8 As shown, during the film pasting process, the entire pasting plate 31 is parallel to the product to be pasted. At this time, an external force needs to be applied to the pasting plate 31 to press the protective film tightly so that the film can be pasted. Another situation is that Fig. 9 As shown, only the movable end 312 is in contact with the product to be laminated, and there is a gap between the side close to the fixed end 311 and the product to be laminated. This design can convert more of the weight of the attachment plate 31 into pressure applied to the pressure roller 32, thereby facilitating the compression of the protective film, which can effectively improve the production cycle.

[0037] In application, the products to be coated include but are not limited to mobile electronic devices, display screens, wooden furniture in spray painting workshops, glass, plastic and other non-metallic materials, etc. The protective film includes but is not limited to tempered film, flexible film and non-metallic surface protective film used on mobile phone screens, etc. The pressure roller 32 includes but is not limited to rollers made of rubber or silicone materials.

[0038] In applications, such as Figure 3 and Figure 6 As shown, a fixing end 311 of the attachment plate 31 is provided with a clearance groove 3110 to facilitate the attachment plate 31 to rotate around the axis.

[0039] In application, the shape of the pores includes but is not limited to circular, elongated, elliptical, and triangular. In one embodiment, circular and elongated shapes are preferred, which are easier to manufacture. In addition, near the protective film tearing hand, the shape of the first pore 310 is elongated, which has a stronger force when adsorbing and is faster when releasing, so as to facilitate the quick attachment of the protective film.

[0040] In some embodiments, Figure 3 and Figure 6 As shown, the attachment assembly 30 further includes a first sealing plate 33. A first groove is formed on the side of the attachment plate 31 away from the protective film. The first sealing plate 33 is embedded in the first groove and forms a first cavity connected to the first air hole 310. This arrangement is to improve the working efficiency of the negative pressure member, avoid air leakage at the first air hole 310, thereby strengthening the negative pressure at the first air hole 310 and ensuring the adsorption and fixation of the protective film.

[0041] In applications, such as Figure 2 As shown, the first negative pressure member is a vacuum generator 16 and an air pipe (not shown in the figure). The vacuum generator 16 is connected to the first cavity through the air pipe. The vacuum generator 16 is used to inhale air, thereby generating negative pressure in the cavity, and adsorbing and fixing the protective film through the first air hole 310, so as to facilitate the subsequent flipping of the attachment plate 31 to perform the film pasting process.

[0042] In some embodiments, Figure 3 and Figure 5 As shown, the base 10 includes a bottom plate 11 and two support arms 12, the support arm 12 is arranged at one end of the bottom plate 11, and the two support arms 12 are arranged on both sides of the bottom plate 11 along the second direction, and the attachment plate 31 is hingedly connected to the two support arms 12 through a hinge shaft 35. By arranging the support arms 12 on the bottom plate 11, and then arranging the bearing assembly 20 on the bottom plate 11, and arranging the attachment assembly 30 on the support arms 12, the overall stability of the entire film attaching device is improved, and it is also convenient to carry, disassemble and use the entire device.

[0043] In applications, such as Figure 3 and Figure 5 As shown, a rubber foot 111 is further provided on the side of the bottom plate 11 away from the bearing assembly 20, so as to alleviate the rigid contact between the bottom plate 11 and the supporting ground. In some embodiments, a roller is further provided on the side of the bottom plate 11 away from the bearing assembly 20 to assist in pushing and facilitate carrying. In some embodiments, a support plate 112 is further provided on the side of the bottom plate 11 close to the bearing assembly 20, and the support plates 112 are provided on both sides of the bottom plate 11 along the second direction, and the support plates 112 are used to assist in supporting the second support plate 22, so as to further improve the stability of the bearing plate 21.

[0044] In use, the attachment plate 31 is hingedly connected to one end of the support arm 12 away from the bottom plate 11 , so as to increase the height of the entire attachment assembly 30 .

[0045] In some embodiments, Figure 3 and Figure 5 As shown, the attachment assembly 30 further includes a first support plate 34, a hinge shaft 35 and two fixing seats 36;

Both ends of the pressing roller 32 are rotatably connected to the two fixing seats 36 .

[0048] The first support plate 34 can better support and fix the attachment plate 31 , and the pressing roller 32 is rotatably arranged at the end of the attachment plate 31 through the fixing seat 36 , so as to press and attach the protective film.

[0049] In applications, such as Figure 5 As shown, a handle 37 is provided on one side of the first support plate 34 away from the attachment plate 31 , so that an operator can easily rotate the attachment assembly 30 to complete the film attachment work.

[0050] In some embodiments, Figures 3 to 5 As shown, the support arm 12 is also provided with a limit block 13, which is located on the side of the support arm 12 away from the bearing assembly 20. The limit block 13 has a support end surface 130 for supporting the attached plate 31, wherein the support end surface 130 is arranged to be inclined upward from a side close to the support arm 12 to a side away from the support arm 12.

[0051] In application, each support arm 12 is provided with a corresponding stopper 13, and the support end face 130 of the stopper 13 is in direct contact with the first support plate 34, so as to support and limit the attachment plate 31. The existence of the stopper 13 is to limit the positioning of the attachment plate 31, so that the attachment plate 31 has a plane or inclined surface that is convenient for placing the protective film. Specifically, when the first support plate 34 is in contact with the support end face 130 of the stopper 13, the acute angle between the plane where the attachment plate 31 is located and the plane where the product to be filmed is located is between 0° and 90°, preferably any angle among 15°, 30°, 45° and 60°.

[0052] In some embodiments, Figure 4As shown, a buffer column 131 is further provided on the support end surface 130. The buffer column 131 is made of silica gel or rubber, so as to buffer the rigid contact between the limit block 13 and the first support plate 34 and avoid wear.

[0053] In some embodiments, Figure 4 As shown, the height of the support end surface 130 in the third direction is higher than the fixed end 311. When the attachment plate 31 abuts against the support end surface 130, the attachment plate 31 is tilted upward toward the side away from the bearing assembly 20. In this way, the positioning and adsorption of the protective film are facilitated.

[0054] In some embodiments, Figure 2 , Figure 3 as well as Figure 5 As shown, the bearing assembly 20 includes a second supporting plate 22, a bearing plate 21 and a positioning block;

Through the cooperation of the above slide rail 24 and the slider 25, the bearing plate 21 is slidably installed in the first direction, thereby facilitating the attachment of the protective film.

[0060] In application, a third support plate 27 is further provided on one side of the second support plate 22 close to the support platform 23 , and the third support plate 27 connects the second support plate 22 and the support platform 23 , thereby improving the stability of the second support plate 22 and the load-bearing plate 21 .

[0061] In application, two slide rails 24 are provided, and four sliders 25 are provided. One slide rail 24 corresponds to two sliders 25, so that the sliding is more stable.
