Description

Technical Field

[0001] The utility model relates to the technical field of polarizer quality inspection equipment, in particular to polarizer foreign body detection equipment. 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.

[0003] Polaroids need to go through multiple quality inspections after production. Only when all inspections are qualified will they be packaged and shipped. The inspection steps include size inspection, function inspection, foreign matter inspection, etc. Most factories still use manual inspection for foreign matter inspection. Due to the limitations of the human eye, the accuracy of foreign matter detection in polaroids is low, and the efficiency cannot be improved. For this reason, we propose a polaroid foreign matter detection device, which uses electronic equipment to replace manual inspection of polaroids to ensure efficiency and quality.

Furthermore, the use of a dual light source detection method can greatly improve the accuracy of detection.

[0007] The utility model is further configured that a gantry is fixed on the end surface of the base plate located outside the auxiliary slideway and the driving slideway, and the detection module is fixed on the top of the gantry.

[0008] By adopting the above technical solution, the installation effect of the detection module is achieved.

[0009] The utility model is further configured such that a first light source for irradiating downwards is installed on the top of the gantry below the detection module, and the first light source is fixed to the gantry through a mounting frame, a damping shaft is connected between the first light source and the mounting frame to achieve angle adjustment of the first light source, and a second light source is installed on the end surface of the substrate below the first light source, and the angle of the second light source is fixed and irradiates vertically upwards.

[0010] By adopting the above technical solution, the effect of providing dual light sources is achieved, which helps to improve the accuracy of detection.

[0011] The utility model is further configured such that the carrier is slidably connected to the inside of the auxiliary slideway and the driving slideway, and a linear motor for driving the carrier to move is installed inside the driving slideway.

[0015] In summary, the utility model mainly has the following beneficial effects:

[0016] 1. The utility model sets an auxiliary slide, a driving slide, a linear motor, a light source and a detection module. First, the polarizer is sucked up from the material tray by a vacuum suction ball, and then the polarizer is placed on the carrier. Further, the linear motor is started, and the linear motor drives the carrier to move. Therefore, the carrier moves forward to the bottom of the detection module under the action of the driving slide and the auxiliary slide. At this time, the polarizer on the carrier is scanned and detected by the detection module under the joint illumination of the first light source and the second light source. Then the staff can take out the material according to the result of the equipment and put it into the corresponding material tray;

[0017] 2. The utility model provides a placement slot, an air suction port and a vacuum pump. When placing the polarizer, the polarizer is first placed in the placement slot to limit its initial position, and then the vacuum pump is started. The vacuum pump will evacuate the placement slot through the air suction port, so that the air pressure above the polarizer is much greater than that below. The resulting air pressure difference will lock the polarizer on the carrier, thereby ensuring the stability of the polarizer and the quality of the detection. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Furthermore, in this embodiment, a gantry 6 is fixed to the end surface of the substrate 2 located outside the auxiliary slide 3 and the driving slide 4, and the detection module 7 is fixed to the top of the gantry 6, and the carrier 10 is made of a fully transparent material.

[0027] See also Figure 1-2The top of the gantry 6 is located below the detection module 7 and is equipped with a first light source 8 that irradiates downward, and the first light source 8 is fixed to the gantry 6 through a mounting frame, and a damping shaft is connected between the first light source 8 and the mounting frame to achieve angle adjustment of the first light source 8, and a second light source 9 is installed on the end surface of the substrate 2 below the first light source 8, and the angle of the second light source 9 is fixed and irradiates vertically upward, providing a dual light source for the detection of the polarizer 11, thereby improving the detection accuracy.

[0028] See also Figure 1-2 The carrier 10 is slidably connected to the auxiliary slide 3 and the driving slide 4, and a linear motor 5 for driving the carrier 10 to move is installed inside the driving slide 4 to achieve the driving effect on the carrier 10.

[0029] See also Figure 3-4 The end face of the carrier 10 is provided with an inwardly recessed placement groove 12, and the bottom wall of the placement groove 12 is provided with multiple groups of air suction ports 13. Each group of air suction ports 13 is connected to the input end of an external vacuum pump through a pipeline to achieve vacuum adsorption limiting of the polarizer 11 and ensure its stability during movement.

[0030] The working principle of the utility model is as follows: first, the polarizer 11 is sucked up from the material tray by a vacuum suction ball, and then the polarizer 11 is placed on the carrier 10. Further, the linear motor 5 is started, and the linear motor 5 drives the carrier 10 to move.
