Description

Technical Field

[0001] The utility model relates to the technical field of lens detection equipment, in particular to a surface defect detection device for resin lenses. Background Art

[0002] Glasses are composed of lenses and frames, and are used to improve eyesight, protect eyes or for decorative purposes. Glasses can correct various vision problems, including myopia, hyperopia, astigmatism, presbyopia, strabismus or amblyopia, etc. Glasses are composed of lenses and frames. When glasses are processed, it is necessary to detect the surface defects of the lenses to determine whether there are cracks and pits on the lens surface.

[0003] When the existing lens surface defect detection equipment is in use, it is necessary to manually place the lens on the support platform of the lens surface defect detection equipment, and collect the lens through the camera for surface defect detection. However, when manually placing and removing the lens, the equipment is in a standby waiting state, and the equipment cannot work continuously, which will affect the efficiency of lens detection.

[0004] Based on this, a device for continuously transporting resin lenses through a transmission mechanism for surface defect detection is designed. Content of the Utility Model

[0005] The utility model aims at the deficiencies existing in the prior art, and provides the following technical solution: a surface defect detection device for resin lenses, including a support platform, a touch screen arranged on the upper surface of the support platform, and a moving frame installed on the support platform for moving in the Y-axis direction. A camera for photographing resin lenses is installed on the moving frame. A transmission mechanism for transporting resin lenses is arranged on the support platform, and a negative pressure member for limiting the resin lenses is further arranged on the upper surface of the support platform.

[0006] As an improvement of the above technical solution, the transmission mechanism includes brackets fixed on both sides of the support platform, and a mesh belt installed on the brackets.

[0007] As an improvement of the above technical solution, the bracket includes side plates fixed on both sides of the support platform. The mesh belt is sleeved outside the two side plates, and a motor roller is installed at the end of the side plate. Retaining rings for preventing the side of the mesh belt from slipping off are welded at both ends of the motor roller, and driven rollers for supporting the mesh belt are rotatably installed on the side plates.

[0008] As an improvement of the above technical solution, the driven rollers are distributed in an array.

[0009] As an improvement of the above technical solution, the negative pressure member includes air permeable holes opened on the upper surface of the support platform, and two negative pressure blowers installed in the air permeable holes. A rubber ring is installed at the upper end of the air permeable hole, and the rubber ring is in contact with the inner surface of the mesh belt.

[0010] As an improvement of the above technical solution, the ventilation holes are arranged in an array on the upper surface of the support table.

[0011] Advantages of the utility model:

[0012] 1. Through the transmission mechanism arranged on the support table, when the resin lens is photographed by the camera on the support table, the feeding and discharging are carried out through the transmission mechanism, so that the camera continuously photographs the resin lens transported on the transmission mechanism, solving the problem that the traditional resin lens is directly placed on the support table, resulting in low detection efficiency due to the intermittent operation of the equipment. And a negative pressure member for limiting the transmission mechanism is arranged on the upper surface of the support table, so that the negative pressure member generates negative pressure, and the resin lens transported on the transmission mechanism is tightly attached to the upper surface of the support table for transmission, ensuring that the resin lens is limited when passing under the camera on the transmission mechanism, and avoiding the resin lens shaking on the transmission mechanism when the transmission mechanism starts and stops.

[0013] 2. Through the transmission mechanism composed of a bracket and a mesh belt, and the bracket is composed of side plates, motor rollers, retaining rings and driven rollers. The side plates are fixed on both sides of the support table, which is convenient for the motor rollers installed at the ends of the two side plates to support the mesh belt. The retaining rings welded at both ends of the motor rollers are used to prevent the mesh belt from running off during transmission, and the driven rollers rotatably installed on the side plates are used to support the mesh belt, so that the mesh belt transports the resin lens when moving.

[0014] 3. Through the negative pressure member composed of ventilation holes, a negative pressure fan and a rubber ring, the ventilation holes are arranged in an array on the upper surface of the support table, and the negative pressure fan installed in the ventilation holes generates a downward air flow when the negative pressure fan is powered on, so that when the mesh belt passes through the upper end of the ventilation holes, the resin lens is tightly attached to the mesh belt under the action of air, avoiding the resin lens shaking when the camera photographs the resin lens due to the stop of the transmission mechanism.

[0022] In this implementation manner, through the transmission mechanism arranged on the support table 1, when the resin lens is photographed by the camera 4 on the support table 1, feeding and discharging are performed through the transmission mechanism, so that the camera 4 continuously photographs the resin lens transported on the transmission mechanism, solving the problem that the traditional resin lens is directly placed on the support table 1, resulting in low detection efficiency due to the intermittent operation of the device. And a negative pressure member 7 for limiting the transmission mechanism is arranged on the upper surface of the support table 1. The negative pressure member 7 generates negative pressure, so that the resin lens transported on the transmission mechanism is closely attached to the upper surface of the support table 1, ensuring that the resin lens is limited when passing under the camera 4 on the transmission mechanism and avoiding the resin lens from shaking on the transmission mechanism when the transmission mechanism starts and stops.

Retaining rings 53 for preventing the side of the mesh belt 6 from slipping off are welded at both ends of the motor roller 52. Driven rollers 54 for supporting the mesh belt 6 are rotatably installed on the side plates 51, and the driven rollers 54 are arranged in an array.

The retaining rings 53 welded at both ends of the motor rollers 52 are used to prevent the mesh belt 6 from running off during transmission, and the driven rollers 54 rotatably installed on the side plates 51 are used to support the mesh belt 6, so that the mesh belt 6 transports the resin lens when moving.

[0025] Specifically, the negative pressure component 7 includes ventilation holes 71 formed on the upper surface of the support platform 1 and two negative pressure fans 72 installed in the ventilation holes 71. A rubber ring 73 is installed at the upper end of the ventilation holes 71, and the rubber ring 73 is in contact with the inner surface of the mesh belt 6. The ventilation holes 71 are arranged in an array on the upper surface of the support platform 1.
