Description

TECHNICAL FIELD

[0001] The utility model mainly relates to the technical field of laminating machine, concretely relates to a curved laminating machine of low tackiness PET film attachment. BACKGROUND

[0002] Laminating machine is mostly used in the attachment of cover plate and film material. With the increasingly vigorous automobile industry, innovative technologies for display screens are emerging, and the requirements for laminating are increasing. Currently, curved laminating machines can only attach high-tackiness ASF and high-tackiness PET, and cannot cope with low-tackiness PET. The reason is that low-tackiness PET, due to low tackiness and electrostatic adsorption, causes the PET to adhere to the steel belt, and cannot be attached to the surface of the cover plate. In the face of increasing product requirements.

[0003] Currently, steel belt attachment can only cope with ASF and high-tackiness PET film, and cannot solve the problem of low-tackiness PET attachment. Manual work is still required, and precision cannot be guaranteed. The solution is to change the traditional steel belt attachment method to a flat plate attachment method, and add a visual target grabbing method. Based on the camera detection function, different product precision requirements can be freely realized. The maximum precision at the present stage can reach 0.1mm, which can meet the common curved attachment orders on the market. UTILITY MODEL CONTENTS
