Description

Technical Field

[0001] The utility model belongs to the technical field of film pasting equipment, in particular to a sheet film automatic pasting equipment. Background Art

[0002] During the processing of some products, some parts need to be coated. For example, in some sensors, waterproof and breathable films, transparent films, etc. need to be attached to the outer shell or pores of the workpiece. Such films generally have a certain bending strength (i.e., they will not bend or deform under certain force conditions).

[0003] At present, the common film laminating equipment on the market usually includes a workpiece placement tool, a film loading assembly, a film placement station, a film removal assembly, and a moving assembly for controlling the transfer of the film removal assembly between the film placement station and the workpiece placement tool (see the schematic diagram of the position relationship). Figure 1 ).

[0004] During the actual use of the above-mentioned film laminating equipment, it was found that the position of the film finally attached to the workpiece was easily inaccurate due to the influence of the stop position of the upper film component, the vibration of the machine during the film removal process, and the scratches between the film placement stations. Therefore, the applicant designed an automatic film laminating equipment that can ensure that the film removal component can correct the position of the film after removing the film.

Then, the moving component drives the film taking component 4 to move above the material belt 204, and the film adjustment component 209 works and makes the position of the sheet film 205 consistent with the material taking direction of the negative pressure suction head. Then, under the action of the lifting component 6, the film taking component 4 descends to take the film, and then the film taking component 4 rises, and the clamping and positioning component controls the clamping claw 81 to approach and adjust the position of the sheet film. After the adjustment, the clamping and positioning component controls the clamping claw 81 to open, and then the moving component controls the film taking component 4 to drive the sheet film to be installed on the workpiece.
