Description

Technical Field

[0001] The utility model relates to the field of products related to polarizing film processing, in particular to a positioning structure for processing polarizing films used in optical instruments. Background Art

[0002] The full name of polarizer is polarizing film. The imaging of LCD must rely on polarized light. All liquid crystals have two polarizing films in the front and back attached to the liquid crystal glass, forming a liquid crystal film with a total thickness of about 1mm. Polarized lenses are recognized worldwide as the most suitable lenses for driving. Since the polarizer itself is relatively weak, a positioning mechanism is required during the polarizer processing process.

[0003] It is difficult for the existing positioning mechanism for processing polarizers to maintain the synchronous rotation of a stack of polarizers during the rotation process. After cutting a set of opposite edges of a stack of polarizers, it is necessary to rotate 90 degrees to cut another set of opposite edges. The abnormal angle dimensions caused by the shaking or deviation of the material often increase the scrap rate during cutting, reducing production efficiency. Utility Model Content

[0006] Preferably, both sides of the support frame are provided with sliding openings, a sliding rod is fixedly connected in the sliding opening, a sliding block is slidably sleeved on the sliding rod, and one end of the sliding block is fixedly connected to the outer wall of the horizontal plate.

[0007] Preferably, four supporting legs are fixedly connected to the bottom of the support frame, and the four supporting legs are respectively fixed at four corners of the bottom of the support frame.

[0008] Preferably, the motor is a servo motor.

[0009] Preferably, the driving gear and the driven gear are both bevel gears.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The positioning structure for processing polarizing film for optical instruments is implemented by placing the polarizing film on a bearing plate and then controlling and starting an electric telescopic cylinder, which prompts the telescopic rod to push the horizontal plate downward. At this time, a pressure plate installed on the bottom of the traction rod will press down and fix the polarizing film. The control and start motor can drive the shaft rod to rotate. When the shaft rod rotates, the driving gear on one end will mesh with the driven gear to realize the rotation of the support rod in the first seat bearing. When the support rod drives the bearing plate to rotate, the pressure plate will prompt the traction rod to realize synchronous rotation in the second seat bearing due to friction. The utility model can avoid material deviation during rotation, improve production efficiency and can adapt to the fixation of polarizing films of different thicknesses.
