Description

Technical Field

[0001] The utility model relates to the technical field of polaroid feeding, in particular to automatic polaroid feeding equipment. Background Art

[0002] Polarizer is a special optical film whose main function is to control the polarization direction of a specific light beam. Polarizers are increasingly used in optics, electronics, communications and other fields, and their role in optics and electronics is becoming increasingly prominent. Currently, manual polarizer production is increasingly unable to meet current production needs in terms of efficiency and quality. Automatic polarizer feeding equipment has become the key to solving the problem of manual polarizer production defects.

[0003] Currently, Chinese patent publication number CN217024423U discloses an automatic feeding device for 15-65 inch polarizers. The device comprises a fixed base and a transport frame. A transmission mechanism is provided on one side of the fixed base. A suction device is fixedly connected to the surface of the fixed base, and a fixing device is provided on the surface of the transport frame. According to the utility model, when the polarizer body needs to be fed, a hydraulic telescopic rod extends and drives the connecting plate downward until the four suction cups at the bottom of the connecting plate are fixed to the polarizer body. The hydraulic telescopic rod retracts and lifts the polarizer body. The rotating gear drives the rotating shaft, thereby rotating the connecting rod and transferring the polarizer body to the conveyor mechanism to complete the next step. Although the device has a simple structure, is easy to operate, saves time and effort, and has strong stability, replacing the manual feeding method, this device still has certain drawbacks. The device uses the suction device to grab the sheet, but there is only one station for placing the sheet, which has a limited number of sheet sacs. When all the sheets on the station are conveyed away, the device needs to stop and load the next group of sheets at the station, which to some extent affects the feeding efficiency.

[0024] There are two grabbing suction cups 10, and both grabbing suction cups 10 are arranged under the connecting plate. A suction cup position adjustment motor 12 for controlling the rotation of the connecting plate is provided above the center position of the connecting plate, and a mounting block 13 for carrying and installing a servo motor is provided at the lower end of the suction cup position adjustment motor 12. The grabbing suction cup 10 and the connecting plate are both arranged under the mounting block 13, and an L-shaped mounting plate 14 is fixedly provided on one side of the mounting block 13. One end of the mounting block 13 is embedded in the interior of a plate on the L-shaped mounting plate 14, and the other end of the L-shaped mounting plate 14 is provided with a servo linear module 15 for controlling the lifting and movement of the plate. The servo linear module 15 is composed of a combination of a servo motor and a screw rod, and the servo linear module 15 is fixedly installed with the movable arm 8, and the movable arm 8 is provided with a reinforcement bracket 16 for reinforcing the servo linear module 15.

[0025] A second protruding plate 17 is fixedly provided on the left side of the equipment base plate 1, and mounting pads 18 are provided above both ends of the second protruding plate 17. A conveying control motor 19 is provided on the upper end of the mounting pad 18.

A screw 24 connected to the conveying control motor 19 is provided above the assembly track 2, and the screw 24 is assembled in the control block 23.

[0026] A measuring module is also provided at the upper end of the second protruding plate 17.

The connecting platform 27 is fixed to one end of the connecting rod 26, and the laser rangefinder 28 is set at a protruding position of the connecting platform 27.

[0027] In the implementation mode of the present invention, since the present invention aims to solve the problem of automatic feeding of polarizers, the structural design of the first conveying base frame 20 and the second conveying base frame 21 in the present invention is specifically for transporting polarizers. After the polarizer raw materials are stacked, they are uniformly placed in the first conveying base frame 20 and the second conveying base frame 21. When the first conveying base frame 20 or the second conveying base frame 21 is fully loaded with polarizer raw materials, the measuring module above the second protruding plate 17 works to measure the thickness of the polarizer raw materials loaded in the first conveying base frame 20 and the second conveying base frame 21. According to the thickness data measured by the measuring module, the actual quantity of the polarizer raw materials can be calculated.

[0028] The equipment is equipped with two independent rail systems, namely the first conveyor frame 20 and the second conveyor frame 21 for transporting raw materials, which operate independently. In this way, the two can alternately undertake different work tasks. When the first conveyor frame 20 is fully loaded with polarizers, it is affected by the conveying control motor 19 and moves forward following the control block 23 and the control piece 22, and comes to the bottom of the grabbing suction cup 10. At this time, the second conveyor frame 21 is still at the initial position, and workers can load the polarizer raw materials into the second conveyor frame 21. After all the polarizer raw materials inside the first conveyor frame 20 are grabbed away, the first conveyor frame 20 is reset to the initial position and the second conveyor frame 21 moves forward, thereby realizing repeated alternating use.

[0029] During the process of grabbing and feeding, the movable arm 8 is controlled by the built-in rotary driver 9, adjusts its own position and comes above the first conveying bottom frame 20 / the second conveying bottom frame 21, and the servo linear module 15 controls the L-shaped mounting plate 14 to descend, and the L-shaped mounting plate 14 drives the height of the entire grabbing mechanism to descend. After the grabbing suction cup 10 adsorbs and grabs the top layer of polarizer raw materials, the servo linear module controls the L-shaped mounting plate 14 to rise. At this time, the built-in rotary driver 9 controls the movable arm 8 to reach above the conveyor belt 4, and the grabbing mechanism puts the polarizer raw materials onto the conveyor belt 4, thus completing a single conveying and feeding work.

[0030] The above is a further detailed description of the present invention in combination with a specific implementation method, and it cannot be determined that the specific implementation of the present invention is limited to this. For technical personnel in the field of the present invention and related technical fields, based on the technical solution of the present invention, any expansion and replacement of operating methods and data should fall within the scope of protection of the present invention.
