[0002] In today's era of rapid technological development, mobile phones, as an indispensable smart device in people's lives, have increasingly stringent requirements for their production and manufacturing processes. Mobile phone glass (CG / BG), as an important component of mobile phones, not only affects the appearance of the phone, but also affects its screen display effect, touch operation experience, and overall quality and safety. In the production process of mobile phone glass, positioning and detection are crucial.

[0003] In the existing field of mechanical equipment inspection, there is a lack of specially designed efficient fixtures for mobile phone glass inspection that requires high-precision inspection and has extremely high requirements for the "three injuries" (scratches, bumps, and abrasions) on the appearance. The traditional positioning method mostly uses a right-angle edge as a reference, and the other two non-reference edges rely on cylinders to push the product into position. This positioning method has many disadvantages: on the one hand, when the rear module takes the material, the up and down movement of the product will scratch the product. To prevent abrasions, the material taking module has to increase the avoidance trajectory when taking the material, which makes the overall production cycle longer and reduces production efficiency; on the other hand, the non-reference edge pushes the product sideways through the cylinder, which is easy to cause damage to the product appearance, such as scratches, bumps, etc., which seriously affects the quality and performance of the product and leads to an increase in the defective rate, which requires improvement. Summary of the invention

When the positioning of the mobile phone glass is completed, the mobile phone glass is sucked by the traceless suction cup arranged at the bottom to avoid the displacement of the mobile phone glass product during high-speed movement, thereby improving the stability and accuracy of the detection.

The flat force-bearing thread is used as the force support of the carrier. The tapered hole force-bearing thread is used to adjust the cylindrical head of the cylindrical adjustment bolt and the tapered hole to ensure that the center position of the carrier does not change during adjustment. The waist-type tapered hole force-bearing thread is used to prevent the carrier from shifting left and right during adjustment by making the cylindrical head of the cylindrical adjustment bolt and the tapered hole tangent. After adjustment, the cylindrical adjustment bolt is supported by the fixed top screw on the side wall of the carrier, and the copper sheet at the front end is used to prevent damage to the thread, thereby ensuring the horizontal stability of the carrier during the detection process and providing a reliable basis for the precise detection of mobile phone glass.
