Description
Technical field
The present invention relates to a kind of proving installation, particularly a kind of proving installation of test light disc intensity.
Background technology
General optical disk is base material with the polycarbonate, and it utilizes injection molding to form the base material of a discs, and then through technologies such as coatings and form a discs.And, when discs when CD-ROM drive runs up, can be because operation errors, the optical drive mechanism assembly error of spindle in optical disc drive motor, insert factor such as discs no-fix, it is too high to add discs material difference or fragility, cause discs to be held and can't stand these external force effects, make discs take place quick-fried.
For avoiding the problems referred to above, the dealer can carry out the discs substrate intensity mostly and measure, existing measuring light disc substrate intensity is to get the part polycarbonate earlier to make test piece, then test piece is put into impact testing machine and carry out the test piece impact, utilize the impact testing machine impact results, learn the intensity of discs base material.Yet shock-testing to the discs base material, it is the test of before the discs injection mo(u)lding, being done, discs can be made the discs of varying strength according to different injection-mold process parameters in addition, so the shock-testing of this discs base material can not be as the test value of real discs intensity.
In addition, the discs base material after injection mo(u)lding does not have the test mode of standard yet, checks the intensity behind the discs substrate forming whether to meet safety standard.So, for test light disc intensity, see also shown in Figure 1ly, often all be that the free-hand 11 pairs of discs 12 of tester are exerted pressure, make discs 12 bendings, to carry out the strength test of discs 12.The artificial free-hand test mode of this kind, can be because the mode that different tester exerts pressure to discs and the difference of power, cause test result variant, add the tester if use the excessive discs that causes of power to break, the fragment 121 that breaks probably has the danger that hurts the tester.
Therefore how to provide a kind of discs proving installation that solves above-mentioned every shortcoming,, show ardent expectation for institute of all circles for the utilization of discs manufacturer.
Summary of the invention
Because above-mentioned problem, the objective of the invention is to overcome the deficiencies in the prior art and defective, a kind of discs proving installation is provided, utilize discs to cause the discs bending because of radial force, before discs is broken, measure the peak power that discs can bear.
For reaching above-mentioned purpose, the invention provides a kind of proving installation, in order to measure the intensity of a discs, comprise one first grip unit, have one first groove; One second grip unit, it is relative with this first grip unit and establish, and has one second groove, wherein this second groove surface is to this first groove, two sides of this discs are positioned respectively in this first groove and this second groove, and this discs is held between this first grip unit and this second grip unit; One detects the unit, and it is located at this first grip unit; And one first unit of exerting pressure, it is linked to this and detects the unit, and applies a pressure in this first grip unit, so that this first grip unit moves to this second grip unit.
From the above, because of according to proving installation of the present invention, first grip unit is moved to second grip unit by first unit of exerting pressure, so that discs is crooked because of being squeezed, and then understanding discs and stressed relation; Before discs is broken, measure the peak power that discs can bear, and then record the intensity and the angle of discs sliver, thus the technological parameter of check discs injection mo(u)lding and the quality of discs.
