Technical Field

The present disclosure relates to the technical field of electronic equipment, and in particular to automatic film sticking equipment and an automatic film sticking method.

Background technique

With the continuous advancement of technology, electronic devices have more and more functions, and there are more and more functional components. Functional components need to be protected by a layer of protective film before assembly to prevent scratches that affect the quality. Most functional components are connected to flexible circuit boards. Since flexible circuit boards are easily damaged, they need to be more protected when applying films to functional components.

When using automatic film laminating equipment to laminar the screen assembly, the flexible circuit board is long and will bend and break during the process of taking and placing the screen assembly. The reliability is poor, and manual lamination is usually used to protect the flexible circuit board.

Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

Fig. 3 is a schematic diagram of a conveying mechanism and a material loading and unloading mechanism according to an exemplary embodiment.

As shown in Figures 1 to 3, the automatic film-sticking device 100 of the embodiment of the present disclosure is used to stick a film material on a material to protect the appearance of the material and effectively protect the flexible circuit board connected to the material. In the following description, the material is described by taking a screen assembly as an example, but the present disclosure is not limited to this.

The automatic film laminating device 100 of the embodiment of the present disclosure may include: a material loading mechanism 20, a film laminating mechanism 40, a material unloading mechanism 30, a conveying mechanism 50, and a wire management mechanism 513. For example, the automatic film laminating device 100 of the present disclosure may also include a frame 10, on which a material inlet 12 for materials (such as screen components) to enter and a film material inlet 11 for film materials to enter are provided.

The material loading mechanism 20 is used to receive materials, such as screen components. The material loading mechanism 20 can be a conveyor belt component, and the materials can be placed on a material tray, and the material tray carrying the materials is conveyed to the mounting station S1 through the conveyor belt.

The film pasting mechanism 40 is used to transfer the film material to the material feeding mechanism 20 and apply the film material to the screen assembly. For example, the film pasting mechanism 40 can be used to apply film to the material at the film pasting station S3.

The material unloading mechanism 30 is used to transfer the film-attached material to the next station, such as the gluing station. The material unloading mechanism 30 can also be a transmission belt assembly, which transfers the film-attached material to the gluing station through the transmission belt.

Fig. 4 is a partial structural schematic diagram of a conveying mechanism according to an exemplary embodiment. As shown in Fig. 3 and Fig. 4 , the conveying mechanism 50 is used to transport the screen assembly from the material loading mechanism 20 to the film attaching mechanism 40 and the material unloading mechanism 30 .

The conveying mechanism 50 may include a mounting seat 511 and a transport suction cup 512 mounted on the mounting seat, wherein the transport suction cup 512 is used to absorb the screen assembly. For example, the transport suction cup 512 may be mounted below the mounting seat 511 .

The cable management mechanism 513 includes a cable management driving member and a toggle member 5134. The toggle member 5134 is connected to the cable management driving member, and the cable management driving member drives the toggle member 5134 to move, so that the toggle member 5134 toggle the flexible circuit board connected to the screen assembly on the transmission mechanism, so that the flexible circuit board is mounted on the toggle member 5134 to prevent the flexible circuit board from being excessively bent.

For example, the cable management drive is provided on the mounting seat 511. The cable management drive can be installed above the mounting seat 511. The toggle member 5134 is provided below the transport suction cup 512, and is used to toggle the flexible circuit board 300 connected to the screen assembly 200 on the transport suction cup 512, so that the flexible circuit board 300 can be mounted on the toggle member 5134, for example, the flexible circuit board 300 can be as close as possible to or almost attached to the back of the display screen assembly (as shown in FIG. 5), so as to prevent the flexible circuit board from being excessively bent, resulting in the possibility of breaking at the connection with the screen assembly.

Taking the screen assembly as an example, the material feeding mechanism 20 receives the screen assembly and transfers the screen assembly to the mounting station S1. The conveying mechanism 50 moves to the mounting station S1 and sucks the display surface of the screen assembly through the suction cup 512 to suck the screen assembly. The conveying mechanism 50 drives the sucked screen assembly to the film-applying station S3 and places the screen assembly on the jig of the film-applying station S3. Among them, the flexible circuit board connected to the screen assembly is located on the back of the screen assembly. Since the screen assembly has a certain length, the flexible circuit board located on the back of the screen assembly is in a bent state in a natural state (under the action of gravity). When the screen assembly is placed on the jig, the flexible circuit board may bend between the back of the screen assembly and the jig, causing the flexible circuit board to fold itself. In particular, when the screen assembly is filmed, due to the action of external force, the bent or folded flexible circuit board may break, resulting in damage.

The present disclosure can solve the problem of bending or folding of the flexible circuit board well through the wire management mechanism 513. The specific working process can be that the suction cup 512 of the conveying mechanism 50 sucks the screen assembly from the material feeding mechanism 20 to drive the screen assembly to rise to a certain height. Then, the wire management driving member of the wire management mechanism 513 drives the toggle member 5134 located below the suction cup 512 to move, and flattens the bent flexible circuit board located on the back of the screen assembly, so that the flexible circuit board is mounted on the toggle member 5134, so that the flexible circuit board is almost attached to the back of the screen assembly. Next, the conveying mechanism 50 drives the screen assembly to move to the film pasting station. Before releasing the screen assembly, the conveying mechanism 50 can be lowered a certain distance so that the distance between the screen assembly and the jig is smaller than the length of the flexible circuit board itself. Then, the wire management drive member drives the toggle member 5134 to move in the opposite direction and causes the suction cup 512 to release the screen assembly. The free end of the flexible circuit board on the back of the screen assembly bends toward the jig under its own gravity and is mounted on the jig. Since the distance between the screen assembly and the jig is smaller than the length of the flexible circuit board, the free end of the flexible circuit board can contact (mount) the jig to prevent the flexible circuit board from folding and breaking itself.

That is to say, the wire management mechanism 513 disclosed in the present invention can make the flexible circuit board on the back of the screen assembly always mounted on the toggle member 5134 during the transportation of the screen assembly, so that the flexible circuit board is almost attached to the screen assembly. In addition, when the wire management mechanism 513 releases the screen assembly on the jig, the free end of the flexible circuit board on the back of the screen assembly is mounted on the jig, so that the flexible circuit board is also almost attached to the back of the screen assembly. Therefore, the automatic film application device disclosed in the present invention can realize automatic film application of the screen assembly, and can also effectively protect the flexible circuit board on the back of the screen assembly, thereby improving the reliability of the display assembly.

In one embodiment, the cable management mechanism 513 further includes a connecting member 5133, the driving end of the cable management driving member is connected to the upper end of the connecting member 5133, and is used to drive the connecting member 5133 to move, and the toggle member 5134 is fixedly or rotatably connected to the lower end of the connecting member 5133. For example, the connecting member 5133 is slidably connected to the mounting seat 511, and a linear guide rail is provided on the mounting seat 511, and the connecting member 5133 is slidably connected to the linear guide rail through a slider. The toggle member 5134 can be a rotating rod, and the rotating rod is rotatably connected to the connecting member 5133 through a bearing.

The rotatable connection of the toggle member 5134 to the connecting member 5133 can reduce the friction between the toggle member 5134 and the flexible circuit board when the toggle member 5134 toggle the flexible circuit board, thereby preventing damage to the flexible circuit board.

In one embodiment, the wire management drive member includes a motor 5131 and a lead screw 5132, and the upper end of the connecting member 5133 is threadedly connected to the lead screw 5132. For example, the motor 5131 is fixed on the mounting seat, the lead screw 5132 is connected to the motor output shaft, and the upper end of the connecting member 5133 is threadedly connected to the lead screw 5132. The forward and reverse rotations of the motor 5131 drive the moving member 5133 to move back and forth. However, it is not limited to this. The wire management drive member can be a telescopic cylinder, the telescopic end of the telescopic cylinder is fixedly connected to the connecting member, and the connecting member is driven to move by the extension and contraction of the driving cylinder, thereby driving the toggle member 5134 to move.

Fig. 6 is a schematic structural diagram of a cleaning mechanism according to an exemplary embodiment.

In one embodiment, as shown in FIG. 2 and FIG. 6 , the automatic film laminating device 100 further includes a cleaning mechanism 60. The cleaning mechanism 60 includes a cleaning bracket 61, a flexible belt unwinding roller 63, a flexible belt recovery roller (not shown) and a flexible belt 64.

The flexible belt discharge roller 63 is rotatably installed on the cleaning bracket 61, located above the support portion 62, and is used to place unused flexible belts. The flexible belt recovery roller is installed on the cleaning bracket 61, and is used to recycle the used flexible belt. The flexible belt is wound around the flexible belt discharge roller 63, and the free end of the flexible belt 64 is sequentially wound around the support portion 62 and the flexible belt recovery roller, and the flexible belt is used to contact and clean the surface of the material. The flexible belt 64 may be a non-woven fabric.

When the screen needs to be wiped, the mobile driving member drives the cleaning bracket 61 to move above the cleaning station S2, and makes the cleaning belt located at the support part 62 contact with the material surface, and drives the flexible belt receiving roller to rotate to move the flexible belt to wipe the screen assembly.

The present invention cooperates with the flexible belt unwinding roller 63, the flexible belt receiving roller and the flexible belt 64 to automatically clean the surface of the material by wiping with the flexible belt 64. Dust and impurities on the surface of the material can be attached to the flexible belt 64 and collected in the flexible belt receiving roller, thereby making the dust and impurities on the surface of the material clean more thoroughly.

In one embodiment, the cleaning mechanism further includes a container 65 and a nozzle 66. The container 65 is disposed on the cleaning bracket 61 and is used to store a cleaning liquid. The nozzle 66 is disposed on the cleaning bracket 61, and the nozzle 66 is connected to the container 65 and is lower than the container 65, and is used to spray the cleaning liquid onto the flexible belt 64. The cleaning liquid can be a foam cleaning agent, alcohol, etc.

In one embodiment, the cleaning mechanism 60 further includes a sponge 67, which is disposed on the support portion 62 of the cleaning bracket 61 and in contact with the inner surface 641 of the flexible belt. The sponge 67 is used to receive the cleaning liquid sprayed by the nozzle 66. Through the contact between the sponge 67 and the inner surface 641 of the flexible belt 64, the cleaning liquid on the sponge can more evenly penetrate into the flexible belt 64, and the part of the flexible belt located at the support portion 62 can always remain in a wet state, so that the material can be cleaned more thoroughly.

When the first conveying mechanism 51 is located at the cleaning mechanism, the second conveying mechanism 52 is located at the film laminating mechanism, and the third conveying mechanism 53 is located at the material unloading mechanism 30.
