[0032] Existing inspection jigs are highly targeted. One inspection jig is dedicated to one type of lens. When inspecting lenses of different types, the inspection jig needs to be replaced. The inspection process is complicated and the replacement of the inspection jig is time-consuming, which makes the efficiency of lens inspection low.
[0033] In view of the above problems, this embodiment provides a lens inspection jig that can be used for lenses of different types, has high universality, and is conducive to improving the inspection efficiency of lenses.
[0034] Specifically, if Figure 1-Figure 3 As shown, the lens detection jig includes a jig body 100, on which a lens placement position 110 is provided. The lens placement position 110 is provided with at least two layers of lens fixing grooves 111. The at least two layers of lens fixing grooves 111 are stacked in a stepped manner. Each layer of lens fixing grooves 111 is used to fix a type of lens. A through detection hole 112 is provided on the bottom wall of the lens fixing groove 111 located at the bottom layer.
[0035] Taking the lens fixing groove 111 having two layers as an example, the lens testing fixture is used to perform performance testing on two different types of lenses. The following briefly introduces the method of using the lens testing fixture (the two different types of lenses are defined as the first lens 11 and the second lens 12):
[0036] First, place the lens inspection jig on the inspection platform of the inspection equipment;
[0037] Then, the first lens 11 is fixed in the lens fixing groove 111 adapted thereto;
[0038] Afterwards, the position of the detection chip of the detection device is adjusted so that the detection chip is focused on the first lens 11 through the detection hole 112;
[0039] Afterwards, the performance testing procedure of the testing equipment is started;
[0040] Finally, after the test is completed, the first lens 11 is removed, and the second lens 12 is installed in another lens fixing groove 111 adapted thereto at the same lens placement position 110 , and the performance test program of the test equipment is started again.
[0041] The lens inspection jig provided in this embodiment provides at least two layers of lens fixing grooves 111 at lens mounting position 110, allowing a single lens mounting position 110 to be used to secure at least two types of lenses. This improves universality compared to existing lens inspection jigs, which can only secure one type of lens. Furthermore, this lens inspection jig can simultaneously inspect at least two types of lenses without requiring frequent jig replacement, thereby improving lens inspection efficiency.
[0042] A through detection hole 112 is provided on the bottom wall of the lens fixing groove 111 located at the bottom layer, and at least two layers of lens fixing grooves 111 are stacked, so that the detection chip of the detection equipment can detect the performance of the lens in each layer of lens fixing grooves 111 at the lens placement position 110 through the detection hole 112, saving the time of adjusting the position of the lens detection fixture or the detection chip, and further improving the lens detection efficiency.
[0043] Furthermore, the diameter of the detection hole 112 can be 14mm-15mm. For example, it can be 14.2mm, 14.4mm, 14.6mm, 14.8mm or 15mm, etc., which can be set according to actual needs, and this application does not make specific limitations. Setting the diameter of the detection hole 112 at 14mm-15mm allows the detection hole 112 to be adapted to most detection chips, further improving the universality of the lens detection fixture, and also facilitating the adjustment of the position of the detection chip to quickly achieve focus between the detection chip and the lens, which is beneficial to improving the detection efficiency of the lens.
[0044] Furthermore, the clearance between the lens and the lens fixing groove 111 is matched. Such a setting can not only ensure the fixing effect of the lens fixing groove 111 on the lens, but also avoid the inner wall of the lens fixing groove 111 and the lens from rubbing against each other during the process of taking and placing the lens, thereby avoiding damage to the lens, and is also conducive to improving the smoothness of taking and placing the lens.
[0045] Optionally, the gap between the outer wall of the lens and the inner wall of the lens fixing groove 111 is 0.5 mm to 1 mm. For example, it can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm or 1 mm, etc., which can be set according to actual needs and is not specifically limited in this application.
[0046] Furthermore, the depth of the lens fixing groove 111 is H1, the length of the lens along its own axial direction is H2, and H1 and H2 satisfy: 2 / 3≤H1 / H2<1. This configuration can improve the stability of the lens fixing groove 111 in fixing the lens.
[0047] Optionally, continue with Figure 1Multiple lens placement positions 110 can be provided on the jig body 100, each of which is provided with at least two layers of lens fixing grooves 111. In other words, by providing multiple lens placement positions 110 on the jig body 100, the jig body 100 can test multiple lenses at once without the need for frequent lens installation and removal during the testing process, thereby improving lens testing efficiency.
[0048] Furthermore, in this embodiment, a plurality of lens placement positions 110 are arranged in an array on the fixture body 100. By arranging the plurality of lens placement positions 110 in an array on the fixture body 100, on the one hand, the lens placement positions 110 are arranged neatly and more aesthetically pleasing; on the other hand, the arrangement of the lens placement positions 110 is regular, which facilitates adjustment of the position of the detection chip.
[0049] Optionally, continue with Figure 2 and Figure 3 In this embodiment, the lens placement position 110 is provided with two layers of lens fixing grooves 111, one of which is a circular groove and the other is a square groove. The diameter of the inscribed circle of the square groove is larger than the diameter of the circular groove. The square groove can be used to fix the lens with a connecting seat ( Figure 3 The second lens 12 in the circular groove can be used to fix the lens without a connecting seat ( Figure 3 The first shot in 11).
[0050] It is understandable that the specific shape of each layer of the lens fixing groove 111 can be adapted according to the shape of the lens to be fixed.
[0051] Optionally, the thickness of the bottom wall of the lens fixing groove 111 at the bottom layer is 0.5 mm-1 mm. Such a setting can ensure the bearing capacity of the fixture body 100 for the lens.
[0052] For example, the thickness of the bottom wall of the lens fixing groove 111 at the bottom layer can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm or 1 mm, etc., which can be set according to actual needs and is not specifically limited in this application.
[0053] Further, see Figure 1 and Figure 2 On the jig body 100, on both sides of the topmost lens fixing groove 111, there are access grooves 120 connected to the lens fixing groove 111. The access grooves 120 are used to remove and place the lens. The provision of the access grooves 120 not only facilitates the removal and placement of the lens, but also facilitates the transportation of the jig body 100.
[0054] It is worth noting that when multiple lens placement positions 110 are set on the fixture body 100, two adjacent lens placement positions 110 can share a placement slot 120. Such a setting can simplify the structure of the lens detection fixture and facilitate processing.
[0055] Optionally, the width a of the pick-and-place slot 120 is 15 mm to 20 mm. For example, it can be 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, or 20 mm, etc., which can be set according to actual needs and is not specifically limited in this application.
[0056] Furthermore, if Figure 4 As shown, the bottom of the jig body 100 is provided with a clearance groove 130 and a contact surface 140 surrounding the clearance groove 130. The contact surface 140 is used to abut against the testing platform of the testing equipment. The provision of the clearance groove 130 can reduce the contact area between the jig body 100 and the testing platform, which helps to improve the flatness of the jig body 100.
[0057] Optionally, the total area of the contact surface 140 may be 25 mm 2 -64mm 2 Such a setting can not only ensure the flatness of the fixture body 100, but also avoid an excessively large contact area. In addition, a smaller contact area is also conducive to maintaining the flatness of the fixture body 100.
[0058] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
