[0038] The following is for reference. Figures 1-4 An optical lens appearance inspection fixture is described in detail with reference to a specific embodiment. It is to be understood that the following description is merely illustrative and not intended to limit the scope of the invention.
[0039] like Figures 1-4 As shown, an optical lens appearance inspection fixture includes a base plate 100 and a pressure plate 150.
[0040] The bottom plate 100 has a positioning groove 110 for accommodating the tray 260 on its top surface. The bottom plate 100 has a first positioning pin 120 and a plurality of magnetic components 130 on the outside of the positioning groove 110. Specifically, the magnetic components 130 can be magnets. Multiple magnetic components 130 are spaced apart. Specifically, the top surface of the base plate 100 has multiple mounting holes 140. The magnetic components 130 are installed in the mounting holes 140. The shape of the magnetic components 130 is cylindrical, which facilitates installation in the mounting holes 140. The pressure plate 150 is made of ferromagnetic material such as steel plate. The pressure plate 150 is connected to the magnetic components 130 by magnetic attraction and is used to press the optical lens 280 onto the tray 260. The pressure plate 150 has a first positioning hole 160 that cooperates with the first positioning pin 120. The pressure plate 150 has multiple observation ports 170 that correspond to the acupoints 270 of the tray 260. The positions of the observation ports 170 correspond to the optical lenses 280. In order to accommodate more optical lenses 280, specifically, the shape of the observation ports 170 is circular, so that it can match the shape of the lens of the optical lens 280. Moreover, the observation ports 170 are arranged in an array and match the acupoints 270 of the tray 260. This arrangement allows more optical lenses 280 to be inspected at once. Before inspection, the optical lens 280 is neatly placed on the acupoint 270 of the tray 260. Then, the tray 260 is placed on the positioning groove 110 on the top surface of the base plate 100. The top surface of the base plate 100 is provided with a first positioning pin 120, which can be installed with the first positioning hole 160 of the pressure plate 150 to play a positioning role, which is conducive to installing the pressure plate 150 onto the base plate 100. Multiple magnetic parts 130 are provided at intervals on the top surface of the base plate 100 outside the positioning groove 110, which can be magnetically connected with the pressure plate 150 to press the optical lens 280 onto the tray 260, mainly pressing the edge part of the optical lens 280. The pressure plate 150 is also provided with multiple observation ports 170 corresponding to the acupoint 270 of the tray 260. The observation ports 170 mainly expose the lens part of the optical lens 280, which can be used to inspect the optical lens 280. Therefore, the optical lens 280 appearance inspection fixture can fix the tray 260 and the product, and during the inspection process, it can be tilted at any angle to inspect the appearance of the product for easy observation. The product will not fall off, thus ensuring the quality of the product.
[0041] like Figure 4As shown, the side of the base plate 100 is provided with a side mounting opening 180. Multiple upwardly extending side limiting plates 190 are mounted to the side mounting opening 180 via screws. These side limiting plates 190 restrict the outer side of the pressure plate 150. The side limiting plates 190 restrict the outer side of the pressure plate 150, facilitating its installation onto the base plate 100. They also provide support when inspecting the product's appearance at an angle, reducing the load on the first locating pin 120 and preventing its deformation. It is understood that the top of the side limiting plates 190 also has an angled design, which serves as a guide, further facilitating the installation of the pressure plate 150.
[0042] like Figure 3 As shown, the positioning groove 110 is rectangular. In some specific embodiments of this utility model, the four corners of the positioning groove 110 are provided with outwardly extending material picking notches 200. The material picking notches 200 in the positioning groove 110 facilitate the removal of the tray 260 from the positioning groove 110 after inspection. Additionally, the bottom surface of the positioning groove 110 is provided with a second positioning pin 210, and the bottom surface of the tray 260 is provided with a second positioning hole that mates with the second positioning pin 210. The second positioning pin 210 on the bottom surface of the positioning groove 110 facilitates its installation with the tray 260. It is understood that the tops of the first positioning pin 120 and the second positioning pin 210 are beveled. The beveled top of the first positioning pin 120 facilitates its installation with the first positioning hole 160 of the pressure plate 150, and the beveled top of the second positioning pin 210 facilitates its installation with the second positioning hole of the tray 260.
[0043] Specifically, such as Figure 2 and Figure 3 As shown, there are three first positioning pins 120 and three first positioning holes 160. The three first positioning pins 120 are located at the three corners of the base plate 100, and the three first positioning holes 160 are located at the three corners of the pressure plate 150. The three first positioning pins 120 are set at the three corners of the base plate 100 and cooperate with the first positioning holes 160 at the three corners of the pressure plate 150 for positioning and installation, which further ensures accurate positioning. At the same time, the triangular layout can provide stable positioning support for the pressure plate 150 and prevent the first positioning pins 120 from deforming.
[0044] Understandably, the top surface of the pressure plate 150 is provided with a recess 220, and multiple observation ports 170 are located within the recess 220. The recess 220 shortens the distance between the top surface of the pressure plate 150 and the optical lens 280, and the observation ports 170 within the recess 220 facilitate inspection of the optical lens 280. Correspondingly, the pressure plate 150 has multiple material-stealing grooves 230 located outside the recess 220. These grooves reduce the weight of the pressure plate 150, making it easier for inspectors to lift and inspect it, thus reducing their workload.
[0045] In some specific embodiments of this utility model, the four sides of the base plate 100 are provided with material-stealing notches 240. Providing material-stealing notches 240 can reduce the weight of the base plate 100, making it easier for inspectors to pick it up and inspect it, thus reducing the burden on inspectors.
[0046] In some specific embodiments of this utility model, the bottom surface of the base plate 100 is provided with four support legs 250, which are located at the four corners of the base plate 100. Specifically, the four support legs 250 are installed on the bottom surface of the base plate 100 by bolts. The support legs 250 at the four corners of the bottom surface of the base plate 100 serve a supporting function, which is beneficial for placement before and after inspection, and also for inspectors to pick up the base plate 100.
[0047] In the description of this specification, references to terms such as "an embodiment," "some embodiments," "illustrative embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0048] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
