[0037] The first embodiment: as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 and Image 6 As shown, the screen glass to be tested is placed on the top surface of the positioning plate 5, the control pump 19 is activated, and the control valve 23 is actuated, so that the control pump 19 sends the hydraulic oil in the oil tank 20 to No. 1 through the control valve 23. In the communication sleeve 24, with the feeding of hydraulic oil, the hydraulic oil is sent into the interior of the entry mechanism 18 through the No. 2 pipe 26, and into the distribution box 10 through the inner cavity of the sleeve 9, and into the distribution box. The hydraulic oil in 10 enters into the movable tube 11 through the No. 1 tube 17, and pushes the sealing plug 13 to slide along the inner surface of the movable tube 11, while the No. 1 spring 12 stretches, so that multiple sets of plywood 15 clamp the screen glass at the same time The side of the lift rod 6 drives the mounting plate...

[0047] Second embodiment: as figure 1 , figure 2 , image 3 , Figure 4 and Figure 7As shown, when the screen glass is turned over and detected, the solenoid valve 30 is activated, so that the hydraulic oil entering the distribution box 10 enters the middle sleeve 313 through the fourth pipe 32. With the increase of the hydraulic oil in the middle sleeve 313, the hydraulic pressure The oil pushes the inner circular plates 312 on both sides to move, and at the same time, the No. 3 spring 315 is stretched, and the sleeve rod 311 pushes the movable tube 11 to move laterally along the side plates 33 on the side of the distribution box 10 , thereby making the adjacent plywood 15 away, so that the clamping position changes, the previously blocked clamping position is automatically opened, and the detection seat 3 on the top is used to conduct a comprehensive inspection, and after a comprehensive inspection is performed on one side, the control valve 23 controls the hydraulic oi...

Abstract

The invention discloses a mobile phone screen glass surface defect detection device in the technical field of screen detection equipment, and discloses a mobile phone screen glass surface defect detection device which comprises a base, a vertical plate is fixedly mounted on the top surface of the base, a detection seat is arranged on the front surface of the vertical plate, and a mounting plate is arranged above the base. According to the invention, a push rod is driven to move through first oil supply to realize rapid clamping of the side surface of screen glass, and after top surface detection is completed, an oil delivery path is changed through a control valve, so that hydraulic oil is delivered into a moving mechanism through a third pipe, and a toothed plate in the moving mechanism is pushed to drive a gear to rotate by 180 degrees; according to the screen glass detection device, the casing pipe drives the distribution box, the movable pipe and the screen glass to turn over, so that secondary detection of the bottom surface of the screen glass is quickly and conveniently realized, manual operation for adjusting and turning over is avoided, the actual turning-over speed is high, the operation is convenient and fast, the operation time is greatly saved, and the detection efficiency of the screen glass is improved.

Description

technical field [0001] The invention relates to the technical field of screen detection equipment, in particular to a mobile phone screen glass surface defect detection device. Background technique [0002] The touch screen glass is mainly used for touch screen panels. It is chemically strengthened glass. The glass material is a special sodium silicate glass material. It improves its own strength through sodium potassium ion exchange to achieve the purpose of glass strengthening. The impact resistance and surface hardness are significantly improved. When used as a mobile phone screen, the surface needs to be inspected for defects during production and processing, and inspection equipment is used for inspection. [0003] In the existing mobile phone screen glass surface defect detection device, during use, a visual detection device is usually installed on the detection top plate, and the screen glass to be detected is placed below, and the screen glass is moved horizontally a...
