Problems solved by technology

However, due to the high price and precision of the special parameter detection machine for optical disc base, most optical disc manufacturers will place the detection machine in a special testing room, so that the CD injection molding machine can be debugged while the optical disc base can be tested on the production line. Thickness brings a lot of inconvenience

Embodiment Construction

[0018] refer to Figure 1 to Figure 5 , a detector for measuring the thickness of the optical disc base, comprising a base 1 with a positioning column 2 at one end, the diameter of the positioning column 2 is smaller than or equal to the aperture of the central hole of the optical disc base 5, so that the optical disc The base 5 can be quickly set on the positioning column 2; the other end of the base 1 is provided with a slide table 3 that can slide horizontally thereon, and here, as a preferred embodiment of the present invention, the base 1 is provided with There is a guide rail 11 that can allow the slide table 3 to move horizontally along it, and the upper surface of the guide rail 11 is provided with several positioning holes 110 that are separated from the positioning column 2 by a certain distance. There are positioning bolts 31 that can be used in conjunction with the positioning holes 110. When the slide table 3 moves to the right above the corresponding positioning ...

Abstract

The invention discloses a detector for measuring the thickness of an optical disc base. The detector comprises a base which is provided with a positioning pillar at one end, wherein a sliding table which can horizontally slide on the base is arranged at the other end of the base, the upper portion of the sliding table horizontally extends in the direction facing towards the positioning pillar to form a horizontal supporting arm, and the free end of the horizontal supporting arm is provided with an instrument head used for measuring the thickness of the optical disc base. Due to the fact that the sliding table which can horizontally move on the base is arranged on the base and the instrument head used for measuring the thickness of the optical disc base is arranged on the sliding table, when the optical disc base is arranged on the positioning pillar, the sliding table which moves horizontally drives the instrument head used for measurement to move leftward and rightward, therefore, the thickness of the peripheral edge of the optical disc base and the thickness of the inner portion of the optical disc base are measured, workers can debug an optical disc injection molding machine in a production line while detecting the thickness of the optical disc base, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a measuring meter, in particular to a measuring meter for measuring the base of an optical disc. Background technique [0002] As we all know, when producing an optical disc base, the thickness of the optical disc base is a very important parameter. Optical disc bases are usually obtained by injection molding through optical disc molds with optical disc injection molding machines. When producing different optical disc bases, it is necessary to adjust the injection molding parameters of the optical disc injection molding machine. Therefore, the staff first need to measure the optical disc bases produced in the test. Determine the difference between the actual thickness and the theoretical thickness, and then adjust the parameters of the disc injection molding machine accordingly. [0003] Now people mainly detect various parameters of the optical disc base, including the thickness of the optical disc base, through a special par...
