Problems solved by technology

[0004] At present, the detection process of magnifying glasses is mainly carried out manually, that is, relying on the inspection personnel to observe the lens with naked eyes. However, due to the small size of bubbles and small cracks, the detection needs to rely on the experience and technology of the inspection personnel, and the detection is more difficult. It is time-consuming and labor-intensive, and the detection efficiency is low. At the same time, it is easy to miss the magnifying glass with defects, resulting in a decline in the pass rate of the magnifying glass.

Embodiment 1

[0045] Present embodiment 1 discloses magnifying glass detection fixture, with reference to figure 1, including a jig body 1, which is provided with two supporting feet 11, and the jig body 1 is also provided with a placement groove 13 with an opening upward and for placing workpieces, and the inner wall of the placement groove 13 abuts against the side wall of the workpiece , the inner wall of the placement groove 13 is provided with an LED lamp 15 .

[0046] The jig body 1 is an arc-shaped groove, arranged horizontally, and an opening is arranged on the top surface. Two supporting feet 11 are provided on the outer wall of the bottom wall of the jig body 1 . to combine figure 2 , the supporting foot 11 is in the shape of a long column and is arranged vertically. A through hole 111 is disposed on the top of the supporting leg 11, and the through hole 111 is matched with a bolt. The supporting feet 11 are threadedly connected with the outer wall of the bottom wall of the j...

Embodiment 2

[0054] refer to image 3 The difference between this embodiment and Embodiment 1 is that the side wall of the placement groove 13 includes three side plates 131 . The side panels 131 are made of elastic material. The side plates 131 are in the shape of a long arc plate, and the plate surface is inclined relative to the bottom wall of the jig body 1 , and the two ends of the three side plates 131 in the length direction are connected end to end to form a placement slot 13 .

[0055] Likewise, the raised portion 18 includes three connecting plates 181 made of elastic material. The connecting plates 181 are in the shape of long arc plates, and the board surfaces are inclined. The three connecting plates 181 are connected end to end to form the raised portion 18 . The three connecting plates 181 correspond to the three side plates 131 one by one, and the top ends of the connecting plates 181 are fixedly connected to the bottom ends of the side plates 131 . An elastic component ...

Embodiment 3

[0060] refer to Figure 5 The difference between this embodiment and Embodiment 1 is that a light-receiving plate 16 for covering the placement groove 13 is provided on the bottom wall of the jig body 1 . The light receiving plate 16 includes a fixed part 161 and a movable part 162. The fixed part 161 is in the shape of a long plate. The movable part 162 is in the shape of an arc plate, and the edge of the movable part 162 is fixedly connected with the end of the fixed part 161 which is far away from the bottom wall of the fixture body 1 in the length direction. catch. The movable part 162 is perpendicular to the fixed part 161 .

[0061] to combine Image 6 A plurality of photoresistors 163 are arranged on the plate surface of the movable part 162 facing the placement groove 13 . The photoresistor 163 spreads over the board surface of the movable part 162 and is fixedly connected with the board surface of the movable part 162 . Reminisce Figure 5 , the photoresistor 16...

Abstract

The invention belongs to the field of magnifying glass detection, and relates to a magnifying glass detection jig and a detection method. The magnifying glass detection jig comprises a jig body, the jig body is provided with a containing groove which is provided with an upward opening and used for containing a workpiece, the containing groove comprises a side wall abutting against the side wall of the workpiece, and the inner wall of the side wall of the containing groove is provided with a lighting piece, the included angle between the incident light of the lighting piece and the side wall of the workpiece is 45-90 degrees. The detection difficulty of the magnifier is reduced, and the detection efficiency of the magnifier is improved.

Description

technical field [0001] The application relates to the field of magnifying glass processing, in particular to a magnifying glass inspection jig. Background technique [0002] The magnifying glass can magnify small objects into images, so that people can observe small objects or structures more clearly and intuitively, which brings great convenience to people's observation process. [0003] During the processing and transportation of the magnifying glass, processing errors or bumps during transportation may cause damage to the magnifying glass, causing defects such as bubbles or small cracks inside the magnifying glass. Inspection, take out the defective magnifying glass for rework, so as to improve the pass rate of the magnifying glass when it leaves the factory. [0004] At present, the detection process of magnifying glasses is mainly carried out manually, that is, relying on the inspection personnel to observe the lens with naked eyes. However, due to the small size of bu...
