Super Pneumatic Finger Lens Impact Test Machine High Performance

Lens Drop Ball Impact Test Machine will test the impact of lenses to meet the applicable ANSI,FDA and European requirement. All the lenses must pass an impact test, known as the "Drop Ball Test": a 16-millimeter steel ball is dropped onto the lens from a height of 1.27 meter

Specification:

1) 5/8-inch steel ball weighing approximately 0.56 ounce

2)Dropped from a height of 50 inches upon the horizontal upper surface of the lens.

3)The ball shall strike within a 5/8 inch diameter circle located at the geometric center of the lens.

4)The ball may be guided but not restricted in its fall by being dropped through a tube extending to within approximately 4 inches of the lens.

5)To pass the test, the lens must not fracture
2)Drop ball System
Drop ball system includes pneumatic finger, lift synchronous belt, cleaning brush, steel ball recycling and reputing system
3) Pneumatic finger
Pneumatic finger is used to clamp and release ball.
4) Lift synchronous belt
Lift synchronous belt delivers the pneumatic finger with steel ball to requested drop height 1.27m.
5) Cleaning brush
Cleaning brush sweep the tested lenses to recycling box
6) Steel ball recycling and reputing System
Steel ball recycling and reputing system will sort out balls from tested lenses and return to initial drop point, wait to be clamped by cylinder finger. Reputing system will automatically supply new steel ball to continue testing once balls can not be returned to initial point.
7) PLC Controler
PLC controller and touch screen panel for easy operation system

What kinds of Lens should test?

1. Q. What are the impact testing requirements for prescription (Rx) glass lenses?

A. The manufacturer must test each finished Rx glass lens individually for impact resistance (21 CFR 801.410(c)(3)). The lens must be capable of withstanding the impact test provided in 21 CFR 801.410(d)(2) as described later in this document under “Testing Apparatus and Procedure.” You should perform testing after the lens has been edged (cut to the shape of the frame) but before the lens is put into the frame.

2.Q. What are the impact testing requirements for non-prescription (over-the-counter) glass lenses, e.g., magnifying spectacles and nonprescription sunglasses?

A. You must test a statistically significant sample of over-the-counter glass lenses from each production batch. The sample must be representative of the finished forms as worn by the wearer, including forms that are of minimal lens thickness and have been subjected to any treatment used to impart impact resistance.
