Hoisting type 3D (Three Dimensional) compatible automatic film sticking machine

Abstract

The invention discloses a hoisting type 3D (Three Dimensional) compatible automatic film sticking machine. The hoisting type 3D compatible automatic film sticking machine comprises a film feeding platform, a transfer platform, a film taking mechanical arm, lower cavity assemblies and upper cavity assemblies, wherein the lower cavity assemblies and the upper cavity assemblies are correspondingly arranged up and down to form film sticking mechanisms; two sets of the film sticking mechanisms are arranged and are arranged on the rack at intervals respectively; the film feeding platform is arrangedbetween the two film sticking mechanisms; a film product to be stuck is placed on the film feeding platform; the transfer platform is arranged above the film feeding platform; the film taking mechanical arm spans across the upper side of the transfer platform; after the film taking mechanical arm takes out the film product on the film feeding platform and puts on the transfer platform, the membrane product is photographed and positioned through the transfer platform; the film taking mechanical arm is used for putting the positioned film product onto the transfer platform; after a position iscorrected through the transfer platform, the film product is put into the lower cavity assemblies through the film taking mechanical arm. By adopting the hoisting type 3D compatible automatic film sticking machine, automatic sticking of the film product is realized and the film sticking efficiency and quality are effectively ensured.

Description

technical field [0001] The invention relates to the field of mechanical automation, in particular to a lift-type 3D compatible automatic film laminating machine. Background technique [0002] Emerging electronic products such as smartphones, tablet computers, and smart wearable devices continue to emerge, and the demand for display screens used to manufacture these electronic products is also increasing year by year; during the manufacturing process of display screens, it is necessary to attach film, PVC, PET, etc. to the surface of the display screen. Attachment of various material membranes; the attachment of membrane materials requires no bubbles, no wrinkles, smoothness, etc. after attachment. Therefore, the film is mostly done in a vacuum environment in order to reduce air bubbles. However, there are the following key technical problems in the actual film sticking process: 1. The existing film sticking machine is used to carry the screen or the carrier of the film mate...

Problems solved by technology

However, there are the following key technical problems in the actual film sticking process: 1. The existing film sticking machine is used to carry the screen or the carrier of the film material. 2. Before the film is attached, it needs to be stretched to the outside and collapsed to reduce the air bubbles when the film is pasted. The traditional collapse film mechanism uses the tension of the spring to collapse. Membranes and springs will continue to accumulate strain after repeated use, and the quality of each collapsed film cannot be guaranteed; 3. The existing membrane material bearing structure needs to move up and down in the sealing structure. After the sealing structure is closed and a vacuum condition is generated, the membrane material will The supporting structure drives the membrane material upwards to fit on the screen; the connection between the membrane material bearing structure and the sealing structure is generally sealed with a rubber sealing ring. This kind of structure requires that the membrane material bearing structure must be kept in the vertical direction when moving up and down. , if there is a skew, it is easy to get stuck, and the glass slag and solid particles in the sealing structure are also easy to cut the rubber sealing ring when the membrane material carrying structure moves up and down, resulting in sealing failure; 4. The upper and lower parts of the sealing structure After closing, it needs to be pressed down and locked by an external mechanism to provide the bearing capacity when sticking the film. However, because the upper part of the sealing structure needs to move up and down, the external mechanism cannot be directly set above the sealing structure so as not to interfere with the movement of the upper part of the sealing structure. It can only be set On the side of the sealing structure, after the sealing structure is closed, move to the top of it, and then press down on the sealing structure; 5. The up and down movement of the membrane material bearing structure in the sealing structure depends on the power components such as the cylinder installed at the lower part of the sealing structure, but Since the membrane material needs to move in the horizontal plane after being placed on the membrane material supporting structure to correct the position, since the membrane material supporting structure is connected with the lower power part, it will inevitably drive the power part to move together when adjusting the position, which needs to be improved; 6. Sealing When the upper part of the structure is closed with the lower part by lifting method, if the traditional screw drive method is adopted, after the upper and lower parts are closed, the two are connected by a rubber sealing ring. After vacuuming, the external air pressure presses down on the rubber sealing ring. The upper part is further lowered, but the screw rod does not move, which directly leads to wire drawing; if the cylinder is used to drive, when the air circuit of the cylinder is disconnected or the circuit is disconnected, the upper part will directly move toward the cylinder without the support of the cylinder thrust. Dropping down, low safety factor; 7. The upper part of the sealed structure needs to be loaded with a screen, the assembly process is cumbersome and inconvenient, and the efficiency is low
