Description

Technical field:

[0001] The utility model relates to a patch detection and shunting mechanism for preparing polarizers. Background technology:

[0002] The full name of polarizer is polarizing film. The imaging of liquid crystal displays must rely on polarized light. All liquid crystals have two polarizing films in front and back tightly attached to the liquid crystal glass, forming a liquid crystal film with a total thickness of about 1mm. It is an indispensable component of liquid crystal imaging technology.

[0003] During polarizer production, they are typically cut and then attached to a placement plate. After the polarizers are attached, they need to be inspected to determine if they are qualified. In existing technology, polarizers are typically inspected by removing the entire plate and then taking it to a testing area for inspection. After inspection, qualified and unqualified polarizers are manually separated, resulting in low efficiency. If polarizers could be inspected immediately after attachment and qualified and unqualified products could be separated, overall production efficiency would be significantly improved, leading to the development of this project. Utility model content:

[0004] The present invention aims to improve the problems existing in the prior art, that is, the technical problem to be solved by the present invention is to provide a patch detection and shunting mechanism for preparing polarizers.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a patch detection and diversion mechanism for the preparation of polarizers, comprising a discharge conveyor belt that penetrates the detection equipment horizontally and conveys the polarizer from left to right, and a qualified product conveyor belt and an unqualified product conveyor belt that are distributed at intervals along the longitudinal direction are provided on the right side of the discharge conveyor belt, and a movable adsorption seat for adsorbing the polarizer output by the discharge conveyor belt is provided between the discharge conveyor belt and the qualified product conveyor belt, and the movable adsorption seat is driven by a longitudinal moving component to move between the qualified product conveyor belt and the unqualified product conveyor belt, and a polarizer moving component for moving the polarizer on the movable adsorption seat to the right is provided above the left end of the qualified product conveyor belt and the unqualified product conveyor belt.

[0006] Furthermore, a plurality of first adsorption holes distributed in a matrix are provided on the top of the movable adsorption seat.

[0007] Furthermore, the longitudinal moving component includes a longitudinal screw rod and longitudinal slide rails arranged parallel to the left and right sides of the longitudinal screw rod. The longitudinal screw rod is screwed to the middle part of the lower end of the movable adsorption seat, and the bottom of the movable adsorption seat slides with the longitudinal slide rail. One end of the longitudinal screw rod is connected to the drive motor, and the drive motor drives the movable adsorption seat to move forward and backward along the longitudinal slide rail through the longitudinal screw rod.

[0008] Furthermore, the polarizer moving assembly includes a horizontally arranged linear moving module, the left end of the linear moving module is located directly above the moving adsorption seat, and a vertically arranged lifting cylinder is fixed to the bottom of the moving end of the linear moving module. The cylinder rod of the lifting cylinder extends downward and a horizontally arranged adsorption plate is fixed at the end, and the adsorption plate is used to adsorb the top of the polarizer.

[0009] Furthermore, a plurality of second adsorption holes distributed in a matrix are provided at the bottom of the adsorption plate.

[0010] Compared with the existing technology, the utility model has the following effects: the structural design of the utility model is simple and reasonable. The polarizer after inspection is moved to the position corresponding to the qualified product conveyor belt and the unqualified product conveyor belt by moving the adsorption seat, and then moved to the conveyor belt with the help of the polarizer moving assembly, so as to realize the diversion output after the polarizer is inspected. Compared with the traditional method of removing the entire plate and then taking it to the inspection area for inspection, the overall production efficiency is effectively improved.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0015] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.

A movable adsorption seat 6 is provided between the conveyor belts 4 for adsorbing the polarizer 3 output by the discharge conveyor belt 1. The movable adsorption seat 6 is connected to the polarizer output by the discharge conveyor belt. The movable adsorption seat 6 is driven by a longitudinal moving component to move between the qualified product conveyor belt 4 and the unqualified product conveyor belt 5. The polarizer after inspection is moved to a position corresponding to the qualified product conveyor belt and the unqualified product conveyor belt through the movable adsorption seat; a polarizer moving component for moving the polarizer 3 on the movable adsorption seat to the right is provided above the left end of the qualified product conveyor belt 4 and the unqualified product conveyor belt 5.

[0017] During operation, the discharge conveyor belt 1 conveys the polarizer 3 after pasting from left to right. When the polarizer 3 passes through the detection device 2, the detection device 2 detects the polarizer, and then outputs it to the mobile adsorption seat 6 through the discharge conveyor belt 1; if the polarizer is qualified after detection by the detection device 2, the mobile adsorption seat 6 remains stationary, and the polarizer moving assembly above the qualified product conveyor belt 4 moves the polarizer on the mobile adsorption seat 6 to the right to the qualified product conveyor belt 4, and is output by the qualified product conveyor belt 4; if the polarizer is unqualified after detection by the detection device 2, the mobile adsorption seat 6 moves forward to the position corresponding to the unqualified product conveyor belt 5, and the polarizer moving assembly above the unqualified product conveyor belt 5 moves the polarizer on the mobile adsorption seat 6 to the right to the unqualified product conveyor belt 5, and is output by the unqualified product conveyor belt 5. The inspected polarizer is moved to the corresponding position of the qualified product conveyor belt and the unqualified product conveyor belt by moving the adsorption seat, and then moved to the conveyor belt with the help of the polarizer moving assembly. In this way, the polarizer is diverted and output after inspection. Compared with the traditional method of removing the entire plate and then taking it to the inspection area for inspection, the overall production efficiency is effectively improved.

[0020] In this embodiment, the polarizer moving assembly includes a horizontally arranged linear motion module 11, the left end of which is located directly above the movable adsorption seat 6. A vertically arranged lifting cylinder 12 is fixed to the bottom of the movable end of the linear motion module 11. The cylinder rod of the lifting cylinder 12 extends downward and is fixed to the end with a horizontally arranged adsorption plate 13. The adsorption plate 13 is used to adsorb the top of the polarizer 3. During operation, the lifting cylinder drives the adsorption plate downward and approaches the movable adsorption seat. The adsorption plate then adsorbs the polarizer, and the lifting cylinder resets upward. After that, the linear motion module drives the lifting cylinder, adsorption plate, and polarizer to move to the right.

[0021] In this embodiment, a plurality of second adsorption holes 14 distributed in a matrix are provided at the bottom of the adsorption plate 13 .
