[0069] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0070] In the automated assembly production line of smart terminal products, operations such as welding, assembly, and pressure holding are very mature, but product packaging automation has always been a difficult point in the entire process. Usually, manual work is required to complete the film application before product packaging. Manual film application is extremely inefficient and its accuracy cannot be guaranteed.

[0071] In view of this, the utility model provides a film pasting device, which realizes the automation of film pasting. By setting an adsorption table to adsorb the protective film placed on the supporting table, the protective film can be fixed, and the accuracy of film pasting is improved. The pressing mechanism presses the part to be pasted placed on the protective film, and the roller of the pushing mechanism rolls on the part to be pasted, thereby realizing all-round film pasting protection for the upper and lower surfaces of the part to be pasted, improving the stability of the protective film attached to the part to be pasted, and improving the efficiency of film pasting.

[0072] The film sticking device provided by the embodiment of the utility model is described below with reference to the accompanying drawings.

[0073] refer to Figure 1 and Figure 2 As shown, the utility model provides a film sticking device, including: a supporting platform 10, a pressing mechanism 20 and a pushing mechanism 30, the supporting platform 10 includes a base 11 and an adsorption table 12, the adsorption table 12 is arranged on the base 11, and the adsorption table 12 is used to adsorb a protective film 70 placed on the adsorption table 12.

[0074] refer to Figure 4 and Figure 5 As shown, the pressing mechanism 20 is disposed on the base 11, and the pressing mechanism 20 is configured to press the film-attached member 60 placed on the protective film 70. Figure 1 , Figure 6 and Figure 7 As shown, the horizontal pushing mechanism 30 is located on the side of the adsorption table 12 , and the horizontal pushing mechanism 30 includes a rotatably arranged roller 33 , and the roller 33 is used to roll on the object 60 to be film-attached so that the protective film 70 is attached to the object 60 to be film-attached.

[0075] The utility model provides a film pasting device, which can fix the protective film 70 placed on the supporting platform 10 by arranging an adsorption table 12, and improve the accuracy of film pasting. The pressing mechanism 20 presses the piece 60 to be pasted with the film placed on the protective film 70, and the roller 33 of the pushing mechanism 30 rolls on the piece 60 to be pasted with the film, so that the upper surface and the lower surface of the piece 60 to be pasted with the film are protected by film pasting in all directions, and the stability of the protective film 70 attached to the piece 60 to be pasted with the film is improved, and the automation of film pasting is realized. Compared with the manual film pasting method, it not only saves time and labor, but also improves the film pasting efficiency.

[0076] The adsorption table 12 is disposed on the supporting platform 10 , and the adsorption table 12 may be directly placed on the base 11 .

[0077] refer to Figure 2 , Figure 7 and Figure 8As shown, the side of the adsorption table 12 facing away from the base 11 is provided with a limiting cavity 13 , the interior of the adsorption table 12 is provided with a negative pressure cavity 121 , and the adsorption table 12 is also provided with an air outlet 122 communicating between the negative pressure cavity 121 and the limiting cavity 13 .

[0078] The adsorption table 12 serves to carry the film-attached piece 60 and the protective film 70. The side wall or bottom wall of the adsorption table 12 has an air suction nozzle, which is used to connect with a negative pressure device, such as a negative pressure pump. Under the action of the negative pressure device, a negative pressure is formed in the negative pressure chamber 121, so that the air between the adsorption table 12 and the protective film 70 placed on the supporting platform 10 is sucked away, thereby stably adsorbing the protective film 70 on the adsorption table 12 to prevent the protective film 70 from falling or shifting.

[0079] refer to Figure 2 , Figure 7 and Figure 8 As shown, the shape of the limiting cavity 13 is adapted to the shape of the main body of the piece 60 to be film-attached, and the limiting cavity 13 is used to limit the main body of the piece 60 to be film-attached, thereby improving the accuracy of the attachment of the protective film 70, preventing the problem of skewed attachment of the protective film 70, and improving the film attachment effect.

[0080] In a possible implementation, the object 60 to be film-coated includes but is not limited to electronic devices such as smart watches, smart bracelets, and mobile phones.

[0081] In one possible implementation, reference Figure 2 , Figure 3 and Figure 4 As shown, the pressing mechanism 20 includes a pressing unit 22, referring to Figure 7 and Fig. 9 As shown, the pressing unit 22 includes a pressing claw 221 and a pressing claw driving member 222 . The pressing claw 221 is disposed on the pressing claw driving member 222 . The pressing claw driving member 222 is used to drive the pressing claw 221 to move along a first direction so that the pressing claw 221 presses the film-attached member 60 .

[0082] The pressing mechanism 20 further includes a first driving member 21, which is disposed on the base 11 and is connected to the pressing claw driving member 222. The first driving member 21 is used to drive the pressing unit 22 to move toward or away from the adsorption table 12 along the second direction. This facilitates the movement of the pressing unit 22. When the pressing unit 22 is not needed to work, the pressing unit 22 can be moved away from the adsorption table 12 along the second direction to prevent the pressing unit 22 from interfering with the taking of the film-attached piece 60.

[0083] The first direction reference Figure 3 and Figure 4 The direction indicated by the arrow Z in the figure is the up and down direction in this example; the second direction refers to Figure 3and Figure 4 The arrow X indicates the direction.

[0084] In a possible implementation, the first driving member 21 may be, for example, a cylinder.

[0085] In one possible implementation, reference Figure 7 and Fig. 9 As shown, the pressing claw driving member 222 is connected to the first driving member 21 , the pressing claw 221 is fixed on the top of the pressing claw driving member 222 , and the pressing claw driving member 222 is used to drive the pressing claw 221 to move along the first direction so that the pressing claw 221 presses the film-attached member 60 .

[0086] In a possible implementation, the pressing claw driving member 222 may be, for example, a cylinder, which pushes the pressing claw 221 to move along the first direction.

[0087] When it is necessary to press the piece to be film-attached 60 placed on the protective film 70, the first driving member 21 drives the pressing unit 22 to approach the adsorption table 12 along the second direction, and makes the pressing claw 221 located on the upper side of the piece to be film-attached 60, and then, the pressing claw driving member 222 drives the pressing claw 221 to move along the first direction so that the pressing claw 221 presses the piece to be film-attached 60.

[0088] In one possible implementation, reference Figure 2 As shown, the pressing claw 221 includes a connecting portion 2211 and a holding portion 2212 which are connected to each other. One end of the connecting portion 2211 is connected to the pressing claw driving member 222 , and the holding portion 2212 is connected to the other end of the connecting portion 2211 .

[0089] The number of the pressing portions 2212 may be two or three, and the two or three pressing portions 2212 may be arranged at intervals. The pressing portions 2212 may be in a strip shape, thereby ensuring a pressing effect on the film-applying member 60 .

[0090] In one possible implementation, in order to prevent the pressing claw 221 from damaging the surface of the piece to be film-attached 60, an elastic sleeve, such as a rubber sleeve or a silicone sleeve, can be provided on the outer surface of the pressing portion 2212, or an elastic pad, such as a rubber pad or a silicone pad, can be adhered to the surface of the pressing portion 2212 facing the piece to be film-attached 60.

[0091] In a possible implementation, there are two pressing units 22, which are respectively located on opposite sides of the support platform 10, and the first driving member 21 is connected between the two pressing units 22. Such a structure can ensure the balance of the force applied by the pressing mechanism 20.

[0092] In a possible implementation, the adsorption table 12 is movably disposed on the base 11 along a first direction.

[0093] refer to Figure 7 and Fig. 9 As shown, when the pressure claw driving member 222 drives the pressure claw 221 to move along the first direction close to the base 11, under the pressure of the pressure claw 221, the film-attaching member 60 and the adsorption table 12 move together along the first direction close to the base 11, thereby driving the adsorption table 12 to move relative to the base 11, and the distance between the adsorption table 12 and the base 11 is reduced.

[0094] The supporting platform 10 also includes an elastic member 14 located between the adsorption table 12 and the base 11. The elastic member 14 is used to realize the resetting of the adsorption table 12. After the distance between the adsorption table 12 and the base 11 is reduced, the elastic member 14 is compressed to store energy. When the pressure claw driving member 222 drives the pressure claw 221 to move away from the base 11 along the first direction and leave the film-attached member 60, the elastic member 14 pushes the adsorption table 12 to move away from the base 11 along the first direction under the action of its own elastic force.

[0095] In addition, the elastic member 14 also serves to protect the piece 60 to be attached to the film. When the downward pressure of the pressure claw 221 on the piece 60 to be attached to the film is too large, the downward pressure of the pressure claw 221 on the piece 60 to be attached to the film can be alleviated by the compression of the elastic member 14 itself, thereby preventing the piece 60 to be attached to the film from being crushed.

[0096] In a possible implementation, the elastic member 14 includes but is not limited to a spring or an elastic sleeve.

[0097] In a possible implementation, the object 60 to be film-attached has a screen and a rear shell. When the object 60 to be film-attached is placed, the screen faces the adsorption table 12 and the rear shell faces away from the adsorption table 12 .

[0098] In some cases, the protective film 70 includes a screen protection section 71 , and the screen protection section 71 needs to be in contact with the screen of the piece 60 to be attached with the film.

[0099] In other cases, reference Figure 8 , Fig.10 and Fig.11 As shown, the protective film 70 includes a screen protection segment 71 and a rear shell protection segment 72 which are connected to each other. The screen protection segment 71 needs to be attached to the screen of the piece 60 to be attached, and the rear shell protection segment 72 needs to be attached to the rear shell of the piece 60 to be attached.

[0100] Considering that when applying the film, there needs to be a corner between the rear shell protection section and the screen protection section 71, so as to better fit with the piece to be applied 60. Therefore, in some possible implementations, the film applying device further includes a pre-bending pusher 40, and the protective film 70 is pre-bent, specifically, the protective film 70 is pre-bent at a position between the rear shell protection section 72 and the screen protection section 71, so as to improve the fitting effect between the protective film 70 and the side wall and the rear shell of the piece to be applied 60.

[0101] In one possible implementation, the pre-bending pusher 40 is disposed on the base 11, and the pre-bending pusher 40 abuts against the opposite side walls of the adsorption table 12. Since the adsorption table 12 is movably disposed on the base 11 along the first direction, relative movement occurs between the adsorption table 12 and the pre-bending pusher 40. The pre-bending pusher 40 pushes the rear shell protection segment 72 of the protective film 70, so that the position between the rear shell protection segment 72 and the screen protection segment 71 is bent, and the folding mark just fits with the edge of the edge of the film-to-be-attached member 60, thereby improving the fitting effect of the protective film 70 and the side wall of the film-to-be-attached member 60.

[0102] In a possible implementation, the pre-bending pusher 40 may be fixed on the base 11 , for example, in the shape of a strip column, and a surface of the pre-bending pusher 40 that contacts the piece to be laminated 60 may be a plane.

[0103] In one possible implementation, reference Figure 2 and Fig.10 As shown, the film sticking device also includes a guide unit 50, which includes a guide block 51 and a guide shaft 52. The guide block 51 is connected to the edge of the adsorption table 12, the first end of the guide shaft 52 is fixedly connected to one of the base 11 and the guide block 51, and the second end of the guide shaft 52 is slidably set in the other of the base 11 and the guide block 51.

[0104] In a possible implementation, the first end of the guide shaft 52 is fixed to the base 11, and the second end of the guide shaft 52 is inserted into the guide block 51 along the first direction and slidably cooperates with the guide block 51, so that a guiding effect is achieved when the adsorption table 12 moves along the first direction. In this example, a guide hole is provided in the guide block 51, and the cross-sectional shape of the guide hole is consistent with the cross-sectional shape of the guide shaft 52.

[0105] In another possible implementation, the first end of the guide shaft 52 is fixedly connected to the guide block 51, and the second end of the guide shaft 52 is inserted into the base 11 along the first direction, and slides with the base 11 to achieve a guiding effect when the adsorption table 12 moves along the first direction. In this example, a mounting hole is provided in the base 11, and a linear bearing is provided in the mounting hole. The second end of the guide shaft 52 slides in the linear bearing, and the movement is smooth and unobstructed.

[0106] In a possible implementation, the elastic member 14 is sleeved on the outer circumference of the guide shaft 52 . Such a structure can prevent the elastic member 14 from falling off, thereby improving the stability of the installation of the elastic member 14 .

[0107] The guide unit 50 provides a guide for the adsorption table 12 to move along the first direction, thereby preventing the adsorption table 12 from being tilted.

[0108] In order to further improve the guiding effect, the number of the guiding units 50 can be 2, 3, 4 or more. When the number of the guiding units 50 is 2, the two guiding units 50 are respectively located on the opposite sides of the adsorption table 12; when the number of the guiding units 50 is 4, the four guiding units 50 are respectively located at the four corners of the adsorption table 12.

[0109] In one possible implementation, reference Figure 1 and Figure 6 As shown, the push mechanism 30 also includes a support frame 34, a second driving member 31 and a roller frame 32. The support frame 34 is located on both sides of the supporting platform 10, the second driving member 31 is arranged at the top of the support frame 34, the roller frame 32 is connected to the second driving member 31, and the roller 33 is rotatably arranged in the roller frame 32. The second driving member 31 is used to push the roller 33 to move closer to or away from the adsorption table 12 along the second direction, so that the roller 33 pushes the rear shell protection section 72 to the upper surface of the film-to-be-laminated member 60, thereby achieving a stable laminating effect.

[0110] In a possible implementation, the second driving member 31 may be, for example, a cylinder.

[0111] In a possible implementation, the roller frame 32 includes a fixed frame 321 and a swing frame 322, wherein the fixed frame 321 is connected to the second driving member 31, the swing frame 322 is pivotally connected to the fixed frame 321, and the roller 33 is rotatably arranged in the swing frame 322. With such a structure, the roller frame 32 can fine-tune the position of the roller 33 while the roller 33 is rolling, so as to prevent the roller 33 from being too high or too low to cause excessive squeezing of the film-applied member 60.

[0112] The swing frame 322 is pivotally connected to the fixed frame 321, and the swing frame 322 can be connected to the fixed frame 321 through a pin. In order to improve the stability of the connection of the swing frame 322, a first open slot is opened in the end of the fixed frame 321, and one end of the swing frame 322 is located in the first open slot. A second open slot is opened at the end of the swing frame 322 away from the fixed frame 321, and the roller 33 is rotatably arranged in the second open slot through a rotating shaft.

[0113] In one possible implementation, reference Figure 1 As shown, there are two horizontal pushing mechanisms 30, which are respectively located on both sides of the adsorption table 12, so that the pushing direction of the two horizontal pushing mechanisms 30 helps to flatten the part of the protective film 70 extending to both sides of the piece to be filmed 60, so that the protective film 70 can better fit with the upper surface of the piece to be filmed 60.

[0114] The utility model provides a film sticking device, which, when working:

[0115] The first step, reference Fig.11 As shown, the protective film 70 is placed on the adsorption table 12 of the carrier 10 , and the negative pressure pump connected to the adsorption table 12 is started, so that the protective film 70 is firmly adsorbed on the adsorption table 12 .

[0116] Step 2: Reference Fig.12 As shown, the piece to be laminated 60 is placed on the protective film 70 placed on the adsorption table 12 , and the side wall of the piece to be laminated 60 abuts against a part of the side wall of the limiting cavity 13 to limit the position of the piece to be laminated 60 .

[0117] Step 3: Reference Fig.13 As shown, the first driving member 21 drives the pressing units 22 on both sides of the carrying platform 10 to move along the second direction close to the adsorption table 12 , that is, the first driving member 21 drives the pressing claws 221 and the pressing claw driving member 222 to move close to the adsorption table 12 .

[0118] Step 4: Reference Fig.14 As shown, the pressing claw 221 of the pressing unit 22 performs a pressing movement, and the pressing claw driving member 222 drives the pressing claw 221 to move in the first direction to press down the film-attached member 60, and the film-attached member 60 is pressed tightly. The film-attached member 60 is pushed downward by the downward pressure of the pressing claw 221, and the adsorption table 12 squeezes the elastic member 14. The elastic member 14 is compressed, and the adsorption table 12 drops to a certain height, which can prevent the problem of excessive pressure of the pressing claw 221 causing damage to the film-attached member 60. Fig.14 As shown, as the adsorption table 12 descends, a relative movement is formed between the adsorption table 12 and the pre-bending pusher 40, and the pre-bending pusher 40 lifts the rear shell protection section 72 of the protective film 70, causing the rear shell protection section 72 to be pre-bent.

[0119] Step 4: Reference Fig.15 As shown, the horizontal pushing mechanism 30 starts to move. The specific action of the horizontal pushing mechanism 30 is: the second driving member 31 pushes the roller frame 32 and the roller 33 to move along the second direction close to the supporting platform 10, so that the roller 33 pushes from the side of the pre-bent rear shell protection segment 72 that is opposite to the to-be-filmed member 60, pushes the rear shell protection segment 72 to the upper surface of the to-be-filmed member 60, and rolls the rear shell protection segment 72 along a straight line to tightly fit the rear shell protection segment 72 and the to-be-filmed member 60.

[0120] The two push mechanisms 30 on both sides of the support platform 10 may be operated successively, so that the rear shell protection sections 72 extending to both sides of the piece 60 to be film-attached can be smoothly attached to the rear shell of the piece 60 to be film-attached, thereby achieving all-round protection for the piece 60 to be film-attached.

[0121] In the fifth step, the second driving member 31 is reset, so that the roller 33 moves away from the supporting platform 10 in the second direction and leaves the piece to be film-attached 60, and the pressing claw driving member 222 is reset and stops pressing down on the piece to be film-attached 60. At this time, under the elastic force of the elastic member 14 itself, the adsorption table 12 moves up and resets. Finally, the first driving member 21 drives the pressing claw 221 and the pressing claw driving member 222 to move as a whole along the second direction away from the supporting platform 10, and the product after film attachment can be taken out.

[0122] The utility model provides a film pasting device, which helps to improve the fully automated production of smart terminal products. It can adhere protective films 70 to 800 pieces 60 to be pasted with films per hour, which is 4 times the speed of manual pasting. The efficiency of film pasting is greatly improved, and the qualified rate of film pasting reaches 99.5%.
