Description

TECHNICAL FIELD

[0002] Special-shaped polarizing plates have become mainstream products applied to mobile phone screens, and users have increasingly high requirements for the processing shape and precision of polarizing plates.

[0003] The traditional polarizing plate production process is to use a die cutter to punch and then use a special-shaped edge grinding machine to grind the edges to obtain a polarizing plate meeting the shape and precision requirements. The specific production process is produced in two modes. One mode is to first spray a code and then directly punch into a target small piece using a die cutter. The other mode is to first spray a code, then punch into a master piece using a die cutter, then manually spray a code, and finally cut into a target small piece through a cutting mechanism. The above two modes both need to use a hydraulic cutting machine, a die cutter, a single machine code sprayer, a small cutting machine, and an edge grinding machine.

[0058] The polarizing sheet processing equipment provided by the present application has the following beneficial effects:

[0059] Compared with the prior art, the polaroid processing equipment of the application cancels the high-cost and high-complexity mechanisms such as hydraulic cutting machines, knife dies, small cutting machines and edge grinding machines in the traditional polaroid processing production line, and replaces them with a laser cutting mechanism to cut the polaroid roll material, thereby obtaining a single polaroid, and the polaroid processing equipment is supplemented with a roll material winding mechanism, an automatic unwinding mechanism, an automatic suction and moving mechanism and a code spraying mechanism to complete the processes of polaroid feeding, feeding, cutting, suction and moving and code spraying, so that the structure and processes of the polaroid processing equipment are simplified, the investment cost is reduced, and the quality of the product is improved.

[0065] A correction sensor is signal-connected to the correction motor and is used to detect the edge position of the polaroid roll material 100 in the width direction.

[0066] The correction sensor is an optical sensor or an ultrasonic sensor.

[0067] In this embodiment, the working principle of the roll material winding mechanism is that the polaroid roll material is conveyed from the roll material winding mechanism to the automatic unwinding mechanism, and in this process, the correction sensor optically detects or detects the vibration frequency of the edge position of the polaroid roll material in the width direction, feeds back the detection signal to the controller, the controller controls the correction motor, the correction motor drives the roll material support according to the detection signal, and the roll material support moves along a direction perpendicular to the conveying direction of the polaroid roll material under the drive of the correction motor, so that the polaroid roll material on the roll material support moves a certain displacement amount in the width direction, thereby achieving the purpose of correction.

[0068] The signal transmission and control relationship between the correction sensor and the correction motor is a known technology, and will not be described herein.

[0069] In an embodiment, the roll-up mechanism 10 comprises:

When the polarizer roll is sent to the processing area of the laser cutting according to the set conveying length, the roll drive motor stops rotating to feed.

[0075] Among them, the signal transmission and control relationship between the position encoder and the roll drive motor belongs to the known technology, and the present application does not make superfluous repetition.

[0076] In an embodiment, the polarizer processing equipment further comprises a workbench, and the laser cutting mechanism comprises:

[0079] Preferably, the laser head drive motor comprises a drive motor and a lead screw in transmission connection with the drive motor, and the laser head mounting rack is in transmission connection with the lead screw, and the laser head mounting rack is stably driven to slide through the lead screw.

[0080] Preferably, the laser cutting mechanism comprises a plurality of laser head mounting racks, and the plurality of laser head mounting racks are arranged at intervals along the direction of conveying the polarizer roll.

The plurality of laser heads move according to the product shape track while emitting laser energy, thereby burning off the polarizing sheet roll material to obtain a single polarizing sheet, and completing the shape processing of the product.

During laser cutting, the automatic suction and moving mechanism performs the work of discharging the material in the discharging area.

At this time, the automatic suction and moving mechanism moves to the cutting area to perform the work of sucking the sheet. Thus, the cycle is repeated.

[0090] The automatic suction and transfer mechanism picks up all the cut and processed finished products as a whole and moves them directly above the conveyor belt. They are then sequentially placed onto the conveyor belt along the direction of the polarizer conveyor belt. Meanwhile, the waste materials on both sides are rolled up by rollers driven by motors.

The output roller 201 and the flattening roller 203 are flush, and the tension roller 202 is lower than the output roller 201 and the flattening roller 203.

[0097] The working principle of the automatic unwinding mechanism is as follows: the polarizing film roll conveyed by the roll feeding mechanism passes through the output roller, tension roller, and flattening roller in sequence before entering the laser cutting mechanism.

[0098] In another embodiment, the laser cutting head in the laser cutting mechanism is fixed relative to the worktable.

[0099] In this embodiment, the polarizer processing equipment further includes:

[0100] The roll cutting mechanism is used to receive the polarizing film roll conveyed by the automatic unwinding mechanism and to cut the polarizing film roll into polarizing film fragments. It can also convey the polarizing film fragments to the fragment moving mechanism. Here, polarizing film fragments refer to the roll cutting mechanism cutting the polarizing film roll into multiple polarizing film fragments in uniform segments.
