Description

Technical Field

[0001] The utility model relates to the technical field of lens production, in particular to a lens disassembly jig and a lens disassembly device. Background Art

[0002] As the speed of lens updates and iterations increases, the old versions of lenses in stock after iteration often need to have their usable glass lenses recycled for reuse.

[0003] Currently, lens disassembly jigs generally include a disassembly base for fixing the lens and a disassembly push rod for pushing the lens out. When disassembling the lens, the disassembly base is glued and fixed to a designated position on the work platform so that the center of the lens on the disassembly base is aligned with the center of the disassembly push rod. The disassembly push rod is then lowered to push the lens out of the frame. However, different lens models currently require dedicated disassembly bases. When replacing the disassembly base, the disassembly base and disassembly push rod need to be realigned, and then the disassembly base needs to be glued and fixed, resulting in lower lens disassembly efficiency. In addition, during the disassembly process, the glue on the disassembly base is easily deteriorated due to prolonged exposure to air, resulting in a decrease in adhesion. The decrease in adhesion will cause the center of the disassembly base to shift, affecting the success rate of disassembly.

[0004] Therefore, it is urgent to provide a lens disassembly jig and a lens disassembly device to solve the above technical problems. Utility Model Content

[0042] Example 1

[0043] This embodiment provides a lens disassembly jig that is fixed by a locking mechanism, which is less likely to cause center deviation during use and improves the efficiency of lens disassembly.

[0044] Specifically, if Figures 1-6 As shown, the lens disassembly fixture includes a disassembly base 100 and a locking mechanism 200 .

[0045] The disassembly base 100 includes a top 110 and a sidewall 120 surrounding the top 110. The top 110 is provided with a lens receiving area for securing the lens to be disassembled. The bottom wall of the sidewall 120 abuts against the lens disassembly workbench 10. The sidewall 120 defines a receiving cavity for accommodating the recovery platform 11 on the lens disassembly workbench 10. The recovery platform 11 is positioned opposite the lens receiving area. A locking mechanism 200 is provided on the sidewall 120 and connected to the recovery platform 11. The locking mechanism 200 can adjust the position of the disassembly base 100 relative to the recovery platform 11.

[0046] When installing the disassembly base 100 on the lens disassembly workbench 10, first align the accommodating cavity with the recovery platform 11; then move the disassembly base 100 so that the side wall portion 120 abuts against the lens disassembly workbench 10, and at this time the recovery platform 11 enters the accommodating cavity; then adjust the position of the disassembly base 100 so that the axis of the lens to be disassembled fixed in the lens accommodating area on the disassembly base 100 coincides with the axis of the disassembly push rod 20 used for disassembling the lens; finally, connect the locking mechanism 200 to the recovery platform 11 to fix the disassembly base 100 on the lens disassembly workbench 10.

[0047] The lens disassembly jig provided in this embodiment has a disassembly base 100 connected to the recovery platform 11 on the lens disassembly workbench 10 via a locking mechanism 200. Compared to the prior art solution of directly gluing the disassembly base to the lens disassembly workbench with glue, on the one hand, it can improve the fixing efficiency of the disassembly base 100, thereby improving the efficiency of lens disassembly; on the other hand, it avoids the problem of center offset caused by the reduced adhesion of glue, which is conducive to ensuring the lens disassembly yield rate. In addition, the locking mechanism 200 can adjust the position of the disassembly base 100 relative to the recovery platform 11. Even if the disassembly base 100 is center offset, it can be easily corrected, and the use is more flexible.

[0048] Further, see Figure 1 and Figure 6 In this embodiment, the locking mechanism 200 includes multiple screws 210. Threaded holes 121 are provided along the circumference of the sidewall 120, corresponding to each screw 210. The threaded holes 121 are connected to the corresponding screws 210, and the tail ends of the multiple screws 210 abut against the outer circumferential wall of the recovery platform 11. The locking mechanism 200 has a simple structure. By rotating the screws 210 to adjust the length of the screws 210 within the accommodating cavity, the position of the disassembly base 100 relative to the recovery platform 11 can be adjusted. Adjusting and securing the disassembly base 100 is relatively simple.

[0049] Optionally, continue with Figure 6 In this embodiment, the diameter of the accommodating cavity is b, the diameter of the recovery platform 11 is a, and a and b satisfy: b ≥ 2a. This arrangement allows a larger adjustment range for the position of the disassembly base 100.

[0050] Optionally, continue with Figure 6 The height of the recovery platform 11 relative to the lens disassembly workbench 10 is d, and the height of the axis of the threaded hole 121 relative to the lens disassembly workbench 10 is c. c and d satisfy the following relationship: d / 2 ≤ c ≤ d-1.5 mm. This arrangement improves the stability of the multiple screws 210 against the recovery platform 11, thereby improving the stability of the disassembly base 100 fixed to the lens disassembly workbench 10.

[0051] Further, see Figure 1 The side wall 120 is provided with an opening 122 communicating with the accommodating cavity, and the opening 122 is arranged opposite to the recycling platform 11. The setting of the opening 122, on the one hand, is convenient for the staff to observe the falling condition of the lens; on the other hand, the disassembled lens can be taken away through the opening 122.

[0052] Optionally, continue with Figure 1 In this embodiment, three screw rods 210 are provided, wherein two screw rods 210 are disposed opposite each other, another screw rod 210 is disposed on one side of the two oppositely disposed screw rods 210, and an opening 122 is disposed on the other side of the two oppositely disposed screw rods 210. Preferably, the other screw rod 210 is perpendicular to the two oppositely disposed screw rods 210.

[0053] Of course, in other embodiments, the number and arrangement of the screws 210 may also be other, and can be set according to actual needs, and this application does not make specific limitations.

[0054] Further, see Figure 3 and Figure 4 The lens accommodation area is a through hole that passes through the top 110. The lens disassembly jig also includes a disassembly head 300. The disassembly head 300 is detachably mounted in the through hole. The disassembly head 300 is provided with a lens fixing hole 310, which is used to fix the lens to be disassembled. By providing a detachable connection between the disassembly head 300 and the disassembly base 100, and fixing the lens to be disassembled on the disassembly head 300, when disassembling lenses of different models, it is only necessary to replace the disassembly head 300 that matches it, without having to replace the disassembly base 100. This improves the compatibility of the lens disassembly jig. In addition, the disassembly base 100 is directly mounted in the through hole, which makes installation and disassembly relatively simple, thereby improving the efficiency of lens disassembly.

[0055] Optionally, continue with Figure 3 and Figure 4 In this embodiment, the through hole includes a first through hole 111 and a second through hole 112 whose axes coincide with each other. The first through hole 111 is positioned above the second through hole 112, and the diameter of the first through hole 111 is larger than the diameter of the second through hole 112. A limiting surface 113 is formed between the first through hole 111 and the second through hole 112. The disassembly receiving head 300 includes a first boss 301 and a second boss 302 whose axes coincide with each other. The diameter of the first boss 301 is larger than the diameter of the second boss 302. The first boss 301 is mounted in the first through hole 111, and the bottom wall of the first boss 301 abuts against the limiting surface 113. The second boss 302 is mounted in the second through hole 112. The stepped first through hole 111 and the second through hole 112 are used to fix the stepped first boss 301 and the second boss 302. The structure is simple, and the disassembly receiving head 300 is convenient for easy removal and placement.

[0056] Optionally, the first boss 301 is clearance-fitted or interference-fitted with the first through hole 111 , and the second boss 302 is clearance-fitted with the second through hole 112 .

[0057] Continue to see Figure 6 In this embodiment, the fitting tolerance between the first boss 301 and the first through hole 111 is ±0.02 mm. The diameter of the second boss 302 is f, and the diameter of the second through hole 112 is g, and g and f satisfy: gf≥1 mm.

[0058] Example 2

[0059] This embodiment provides a lens disassembly device, comprising a lens disassembly workbench 10, a disassembly push rod 20, a driving member (not shown in the figure), and the lens disassembly jig provided in the first embodiment.

[0060] Since the lens disassembly device adopts the above-mentioned lens disassembly fixture, the efficiency and yield of lens disassembly are both high.

[0061] Specifically, if Figure 5 As shown, a lens disassembly workbench 10 is provided with a recovery platform 11 for receiving lenses. The disassembly base 100 of the lens disassembly jig is connected to the recovery platform 11 via a locking mechanism 200. A disassembly push rod 20 is positioned above and opposite the center of the recovery platform 11. A drive member is connected to the disassembly push rod 20, driving it upward and downward to eject the lens from the lens to be disassembled, which is secured to the disassembly base 100.

[0062] The steps to disassemble the lens using the lens disassembly device are as follows:

[0063] First, fix the lens disassembly jig on the lens disassembly workbench 10, and make the center of the lens accommodating area face the center of the disassembly push rod 20;

[0064] Then, fix the lens to be disassembled on the lens accommodating area, and make the center of the lens accommodating area coincide with the center of the lens;

[0065] Finally, the driving member is started, and the disassembling push rod 20 is controlled by the driving member to descend until the disassembling push rod 20 pushes the lens of the lens out of the lens frame, and the pushed lens falls onto the recovery platform 11.

[0066] Further, see Figure 5 The recycling station 11 is provided with a recycling box 30 for receiving lenses. The opening of the recycling box 30 is opposite to the lens storage area. Lenses pushed out of the frames by the disassembled push rod 20 fall into the recycling box 30. The recycling box 30 can accommodate more lenses, reducing the frequency of removing lenses.

[0067] 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.
