Embodiment approach

[0024] In further embodiments of the present invention, please continue to refer to figure 1 and figure 2 shown. The pressing mechanism 3 has a driving device, and the PLC controller 4 is connected with the driving device signal, so that the PLC controller 4 sends a signal to the driving device, and the driving device drives the pressing mechanism 3 to realize the up and down pressing action.

[0025] In a further embodiment of the present invention, taking a preferred embodiment as an example, the driving device is a double-rod cylinder, specifically an SMC double-rod cylinder. The pressing down mechanism 3 realizes the pressing down action through the double-rod cylinder, so as to press down a plurality of sheet metal trays 21 of the sheet metal positioning tray mechanism 2 .

[0026] In a further embodiment of the present invention, the pressing mechanism 3 has several pressing rubber heads 31, each pressing rubber head 31 faces each sheet metal tray 21, and each pressin...

Abstract

The invention discloses a polarizer push fixture and a work mode thereof. The polarizer push fixture comprises a rack, a metal plate positioning tray mechanism mounted at the upper end of the rack, a pressing-down mechanism located above the metal plate positioning tray mechanism, and a PLC (Programmable Logic Controller) in signal connection with the pressing-down mechanism. The work mode comprises the following steps: 1, placing a metal plate in a metal plate tray; 2, placing the metal plate positioning tray mechanism at the upper end of the rack; 3, opening a drive switch and controlling the pressing-down mechanism to descend and compress a polarizer and the metal plate by the PLC; 4, enabling the pressing-down mechanism to ascend automatically after the pressing-down mechanism performs pressing down for 12 seconds; 5, taking the metal plate positioning tray mechanism out from the polarizer push fixture; 6, taking the metal plate out from the metal plate tray. By adopting the polarizer push fixture and the work mode, a press-attaching rubber head of the pressing-down mechanism is in contact with the polarizer, so that the polarizer and the metal plate are fitted closely and adhered firmly, and the firm adhesion of the polarizer on the metal plate is ensured, and the whole operation is convenient and effective.

Description

technical field [0001] The invention relates to the technical field of a pushing jig, in particular to a pushing jig for an optical-mechanical polarizing plate of a projector. Background technique [0002] At present, in the production process of optical projectors, the optical-mechanical polarizing plate of the projector needs to be attached and bonded to the sheet metal with double-sided tape, that is, a certain pressure is used to make the polarizing plate and the sheet metal pressed together with double-sided tape After a period of time, the polarizer is firmly bonded to the sheet metal. [0003] In the existing polarizing plate pushing fixture, the rubber head and the pressing mechanism are fixed with a spring and a guide shaft, so that when several polarizing plates are attached at the same time, the rubber head can be pressed and the force is basically the same. However, the existing polarizing plate pushing jig is mainly used for uniform force, and does not involve ...
