Description

Technical Field

[0001] The utility model relates to the technical field of optical lens manufacturing, in particular to a spacer assembly jig. Background Art

[0002] Metal spacers are very common in the structural design of optical zoom lenses. There are generally two installation methods for spacers. One is to use tweezers to put the spacer into the lens frame and then use a pressing pen to forcibly flatten the spacer. However, during the flattening process, there is often strong vibration, which easily affects the installation accuracy of the lens cooperating with the spacer. Moreover, it is easy to install the spacer obliquely with tweezers, resulting in incomplete pressing, which in turn affects the assembly of the next part of the lens and the imaging quality of the lens. The other is to adsorb the spacer with a spacer suction pen and then install the spacer into the lens frame. This installation method has a lower risk of the spacer being installed obliquely. However, currently, the spacer suction pen can only be used for spacers of a single size, with poor versatility, complex structure, and poor stability.

[0003] Therefore, it is urgent to propose a spacer assembly jig to solve the above technical problems. Summary of the Utility Model

[0004] The utility model provides a spacer assembly jig, which can be applicable to spacers of various sizes, has high universality, and has a simple structure and high structural stability.

[0007] A suction head, which is in clearance fit with the lens frame. The suction head includes an adsorption end and a connection end disposed opposite to the adsorption end. An air inlet groove is provided in the middle of the connection end. A plurality of radial gas passages extending along the radial direction of the suction head are provided on the circumferential direction of the suction head. The first end of the radial gas passage communicates with the air inlet groove, and the second end of the radial gas passage is located on the outer peripheral wall of the suction head and is blocked by a plug. A plurality of adsorption holes extending along the axial direction of the suction head are provided on the adsorption end. The adsorption holes are arranged in one-to-one correspondence with the radial gas passages, and the adsorption holes communicate with their corresponding radial gas passages. The adsorption holes are used for adsorbing the spacer;

[0008] A suction pen rod, which is detachably connected to the connection end. A through suction channel is provided in the suction pen rod. One end of the suction channel communicates with the air inlet groove, and the other end of the suction channel is used to be connected to the air pipe of a suction device.

[0009] Optionally, a first relief groove is provided in the middle of the adsorption end. The first relief groove is used to avoid the lens in the spectacle frame. The part of the adsorption end surrounding the first relief groove is the adsorption surface. The adsorption holes are arranged on the adsorption surface, and the adsorption surface is used to support the spacer ring.

[0010] Optionally, a plurality of exhaust holes penetrating the suction pen tip are provided at the bottom of the first relief groove, and the exhaust holes are arranged in a dislocation manner with the radial gas passage.

[0011] Optionally, an annular flange is provided on the adsorption surface, and the outer peripheral wall of the annular flange abuts against the inner peripheral wall of the spacer ring.

[0018] Advantages of the utility model:

[0019] The utility model provides a spacer assembly jig, which comprises a suction pen tip and a suction pen rod. The suction pen tip includes an adsorption end and a connection end. An air inlet groove is arranged on the connection end. A plurality of adsorption holes are arranged along the circumferential direction of the adsorption end. The adsorption holes are communicated with the air inlet groove through a radial gas passage on the suction pen tip. The suction pen rod is detachably connected to the connection end. An air suction passage is arranged in the suction pen rod. An air suction device is communicated with the air suction passage through an air pipe. When using this spacer assembly jig to assemble a spacer, first start the air suction device. External air will be sucked away successively through the adsorption holes, the radial gas passage, the air inlet groove and the air suction passage, so that the adsorption holes have adsorption force to adsorb the spacer. Then the suction pen tip and the spacer enter the spectacle frame together. After the spacer is sent to the installation position in the spectacle frame, turn off the air suction device to make the spacer detach, and then remove this spacer assembly jig. By setting the clearance fit between the suction pen tip and the spectacle frame, the installation of the spacer is not easy to be skewed, which is convenient for subsequent pressing of the spacer. Moreover, the adsorption holes, the radial gas passage and the air inlet groove are all directly processed on the suction pen tip, and the structural stability is relatively high. In addition, by setting the detachable connection between the suction pen tip and the suction pen rod, the suction pen tip matching the size of the spacer to be assembled can be replaced, so that the universality of this spacer assembly jig is relatively high.

In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.

[0034] This embodiment provides a spacer assembly jig, which can be applicable to spacers of various sizes, has a high universality, and has a simple structure and high structural stability.

[0035] Specifically, as Figures 1-5 shown, the spacer assembling jig includes a suction pen tip 100 and a suction pen rod 200.

[0036] Among them, the suction pen tip 100 is in clearance fit with the lens frame 20. The suction pen tip 100 includes an adsorption end and a connection end disposed opposite to the adsorption end. An air inlet groove 110 is provided in the middle of the connection end. A plurality of radial gas passages 120 extending along the radial direction of the suction pen tip 100 are provided on the circumferential direction of the suction pen tip 100. The first end of the radial gas passage 120 is communicated with the air inlet groove 110. The second end of the radial gas passage 120 is located on the outer peripheral wall of the suction pen tip 100 and is blocked by a plug. A plurality of adsorption holes 130 extending along the axial direction of the suction pen tip 100 are provided on the adsorption end. The adsorption holes 130 are arranged in one-to-one correspondence with the radial gas passages 120. The adsorption holes 130 are communicated with their corresponding radial gas passages 120. The adsorption holes 130 are used for adsorbing the spacer 10. That is, the adsorption holes 130, the radial gas passages 120 and the air inlet groove 110 form a passage for gas flow.

[0037] The suction pen rod 200 is detachably connected to the connection end. A through suction channel 210 is provided in the suction pen rod 200. One end of the suction channel 210 is communicated with the air inlet groove 110. The other end of the suction channel 210 is used for connecting with the air pipe 40 of the suction device.

[0038] The steps of using this spacer assembling jig to assemble the spacer 10 are as follows:

[0039] First, start the suction device. The outside air will sequentially enter the suction device through the adsorption holes 130, the radial gas passages 120, the air inlet groove 110, the suction channel 210 and the air pipe 40. In this way, the adsorption holes 130 have adsorption force, and the spacer 10 is adsorbed on the adsorption end through this adsorption force;

[0040] Then, move this spacer assembling jig so that the suction pen tip 100 adsorbed with the spacer 10 enters the lens frame 20. Since the suction pen tip 100 is in clearance fit with the lens frame 20, the spacer 10 can be restricted by the limit between the lens frame 20 and the suction pen tip 100. When the spacer 10 is loaded into the lens frame 20 through the suction pen tip 100, the risk of the spacer 10 being skewed is relatively low, reducing the risk of the subsequent spacer 10 being under-pressed, and thus ensuring to a certain extent the assembly reliability of the next part of the lens and the imaging quality of the lens;

[0041] Finally, after the spacer 10 is installed in place, turn off the suction device. At this time, the adsorption holes 130 of the suction pen tip 100 lose the adsorption force on the spacer 10, causing the suction pen tip 100 to separate from the spacer 10. Move this spacer assembling jig to make it leave the lens frame 20.

[0042] The spacer assembling jig provided in this embodiment has a high structural stability as its adsorption holes 130, radial gas passages 120, and air inlet grooves 110 are all directly machined on the suction pen tip 100. Moreover, by setting the suction pen tip 100 to be detachably connected to the suction pen rod 200, the suction pen tip 100 that matches the size of the spacer 10 to be assembled can be replaced, making the spacer assembling jig highly versatile.

[0043] Optionally, in this embodiment, both the adsorption holes 130 and the radial gas passages 120 are provided with 12. In other embodiments, the numbers of the adsorption holes 130 and the radial gas passages 120 can also be set to other values, which can be set according to actual needs, and the present application does not make specific limitations.

[0044] Optionally, multiple adsorption holes 130 and multiple radial gas passages 120 are both arranged at equal intervals along the circumferential direction of the suction pen tip 100. With this arrangement, the force on each part of the spacer 10 can be relatively uniform, and the effect of adsorbing the spacer 10 is better.

[0045] Optionally, continue to refer to Figure 1 In this embodiment, the air suction channel 210 is in interference fit with the trachea 40. With this arrangement, it is convenient for the installation and disassembly between the spacer assembling jig and the trachea 40.

[0046] Furthermore, continue to refer to Figures 1-3 A first avoidance groove 140 is provided in the middle of the adsorption end. The first avoidance groove 140 is used to avoid the lens 30 in the spectacle frame 20. The part of the adsorption end surrounding the first avoidance groove 140 is the adsorption surface 150. The adsorption holes 130 are arranged on the adsorption surface 150, and the adsorption surface 150 is used to support the spacer 10. By providing the first avoidance groove 140, it can be avoided that the suction pen tip 100 interferes with the lens 30, resulting in the spacer 10 not being properly installed. With this arrangement, the spacer assembling jig is also applicable to the assembly of the spacer 10 for a convex lens and the assembly of the spacer 10 for a concave lens, improving the versatility of the spacer assembling jig.

[0047] Optionally, continue to refer to Figure 3 and Figure 5 A number of exhaust holes 160 penetrating the suction pen tip 100 are provided at the bottom of the first avoidance groove 140. The exhaust holes 160 are arranged in a staggered manner with the radial gas passages 120. By providing the exhaust holes 160, it can be avoided that too much gas between the first avoidance groove 140 and the lens 30 affects the suction pen tip 100 from entering the interior of the spectacle frame 20, resulting in the spacer 10 not being properly installed.

[0048] Optionally, the number of the exhaust holes 160 can be one or multiple, which can be set according to actual needs. Continue to refer to Figure 5, in this embodiment, there are four exhaust holes 160, and the four exhaust holes 160 are arranged at equal intervals along the circumferential direction of the suction head 100.

[0049] Further, continue to refer to Figure 2 and Figure 3 , an annular flange 170 is provided on the adsorption surface 150, and the outer peripheral wall of the annular flange 170 abuts against the inner peripheral wall of the spacer 10. By providing the annular flange 170, on the one hand, the position of the spacer 10 on the suction head 100 can be limited, further reducing the risk of the spacer 10 being installed obliquely; on the other hand, the contact area between the spacer 10 and the suction head 100 is increased, thereby improving the adsorption reliability of the suction head 100 to the spacer 10.

[0050] Optionally, the length of the annular flange 170 in the axial direction of the suction head 100 is 1.3 mm - 1.5 mm.

[0051] Further, continue to refer to Figures 2-4 , a second avoidance groove 180 is provided on the outer peripheral wall of the suction head 100, and a convex portion 21 is provided on the inner peripheral wall of the frame 20, and the convex portion 21 enters the second avoidance groove 180. By providing the second avoidance groove 180, the convex portion 21 on the frame 20 can be avoided to ensure that the spacer 10 can be installed in place.

[0052] Optionally, the depth of the second avoidance groove 180 in the radial direction of the suction head 100 is 0.2 mm - 0.3 mm.

[0053] Further, continue to refer to Figure 1 and Figure 4 , a connector 190 is provided around the outer edge of the air inlet groove 110, the connector 190 is provided with an external thread, and one end of the air suction channel 210 is provided with an internal thread, and the suction pen rod 200 is connected to the external thread of the connector 190 through the internal thread. The threaded connection structure is simple, which is convenient for the installation and disassembly between the suction head 100 and the suction pen rod 200, and the connection strength is relatively high.

[0054] Optionally, the material of the suction pen rod 200 can be polyoxymethylene (POM plastic), and the material of the suction head 100 can be a metal material. In this way, both the strength of the suction head 100 can be ensured and the weight can be reduced through the suction pen rod 200.

[0055] Optionally, in a possible embodiment, the second end of the radial gas passage 120 is filled with a colloid, and this colloid is the plug. The second end of the radial gas passage 120 is blocked by the colloid, which is convenient for processing, has a better blocking effect, lower cost, and will not increase the weight of the suction head 100.

[0056] Optionally, in another possible embodiment, the plug includes a head (not shown in the figure) and a rod portion connected to the head (not shown in the figure), and the rod portion is in interference fit with the second end. The plug has a simple structure, is convenient for assembly, and has a better plugging effect.

[0057] Further, continuing to refer to Figure 4 , mounting grooves 121 corresponding one-to-one to the radial gas passages 120 are provided on the outer peripheral wall of the suction head 100, the head is placed in the mounting groove 121, and the head does not protrude from the mounting groove 121 in the radial direction of the suction head 100. With such a setting, it can not only avoid interference between the head and the spectacle frame 20, but also make the structure of the suction head 100 more beautiful.

[0058] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here.
