The machine vision lens is a key component for forming a machine vision system. At present, in a machine vision lens, an object distance adjusting ring is connected with an inner adjusting ring in a lens barrel assembly through three machine screws. In order to ensure the firmness of connection, glue filling treatment is carried out on the threaded holes for installing the machine meter screws, namely after the three machine meter screws are locked, two of the three machine meter screws are taken down, a certain amount of glue is filled into the threaded holes of the three machine meter screws, and then the two taken down machine meter screws are locked again; and finally, performing glue filling treatment on the threaded hole of the remaining machine meter screw and re-locking the machine meter screw.

Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.

In the prior art, as shown in fig. 1, in a machine vision lens, an object distance adjusting ring 101 is connected to an inner adjusting ring 104 in a lens barrel assembly through a screw 105, and a screw hole where the screw 105 is located is filled with glue. The inner adjusting ring 104 is fixedly connected with the lens fixing barrel 102 in the lens barrel assembly through a fastener 103.

Example one

The embodiment provides a lens disassembling jig. As shown in fig. 2, the lens disassembling jig includes a fixing mechanism 1, a rotating member 2 and a handle 3. Specifically, the fixing mechanism 1 is mounted on a lens barrel assembly of a lens to be disassembled, for preventing an inner adjusting ring 104 in the lens barrel assembly from rotating around an axis of the lens to be disassembled. The rotating part 2 is installed on the object distance adjusting ring 101 of the lens to be disassembled and is used for driving the object distance adjusting ring 101 to rotate around the axis of the lens to be disassembled. The handle 3 is fixedly connected with the rotating part 2 and is used for providing a force arm for the rotation of the object distance adjusting ring 101. Under the premise of unscrewing the machine screw 105 in advance, according to the arrangement, the object distance adjusting ring 101 can rotate relative to the inner adjusting ring 104, so that the object distance adjusting ring 101 is separated from the inner adjusting ring 104, and the object distance adjusting ring 101 is disassembled. Meanwhile, due to the existence of the rotating force arm, a labor-saving lever can be formed, so that an operator can easily rotate the object distance adjusting ring 101 through the rotating part 2 to overcome the viscous force effect of glue, acetone does not need to permeate for many times, time and labor are saved, and the disassembling efficiency is improved. In this embodiment, the handle 3 is configured as a round bar structure, and is fixedly installed on the side surface of the rotating member 2, and the axis of the handle 3 is perpendicular to the axis of the lens to be disassembled.

Alternatively, the rotating member 2 is mounted on the outer portion of the object distance adjusting ring 101. Specifically, in the present embodiment, as shown in fig. 3, the rotating member 2 is a dome-shaped structure, and a cylindrical mounting groove 22 is provided at the bottom thereof. The rotating member 2 may be fastened to the object distance adjusting ring 101 from the top down such that the object distance adjusting ring 101 is inserted into the mounting groove 22. In order to improve the friction force between the object distance adjusting ring 101 and the rotating part 2 and avoid the relative rotation of the rotating part 2 relative to the object distance adjusting ring 101, the surface of the rotating part 2 in contact with the object distance adjusting ring 101 is also provided with a concave-convex structure 21, and the concave-convex structure 21 is matched with the lines 1011 on the outer circumferential surface of the object distance adjusting ring 101. According to the arrangement, even if the size of the object distance adjusting ring 101 is very small, a large rotating moment can be conveniently applied to the object distance adjusting ring 101 through the rotating part 2 and the handle 3 so as to disassemble the object distance adjusting ring 101.

Alternatively, as shown in fig. 2, the fixing mechanism 1 includes a first fixing member 11, and the first fixing member 11 is used for preventing the lens fixing barrel 102 in the lens barrel assembly from rotating around the axis of the lens to be disassembled. In fact, as can be seen from fig. 1, since the inner adjusting ring 104 and the lens fixing barrel 102 are relatively fixed, the inner adjusting ring 104 can be prevented from rotating around the axis of the lens to be disassembled only by preventing the lens fixing barrel 102 from rotating around the axis of the lens to be disassembled. At this time, the object distance adjusting ring 101 is applied with force by the rotating part 2 and the handle 3, so that the object distance adjusting ring 101 and the inner adjusting ring 104 can be separated, and the object distance adjusting ring 101 is disassembled without limiting the rotation of the whole lens barrel assembly around the axis of the lens to be disassembled.

Alternatively, as shown in fig. 2, a limit groove 111 is provided on the first fixing member 11, and the fastening member 103 provided on the lens fixing barrel 102 is engaged in the limit groove 111. Under the matching of the limiting groove 111 and the fastening piece 103, the first fixing piece 11 can prevent the lens fixing barrel 102 from rotating around the axis of the lens to be disassembled. In this embodiment, the number of the limiting grooves 111 corresponds to the number of the fastening members 103, and is 3.

Further, it is considered that, when the object distance adjusting ring 101 is rotated by the rotating member 2 and the handle 3, the fastening member 103 may be subjected to a large torsion force before the object distance adjusting ring 101 and the inner adjusting ring 104 are separated, which may cause the fastening member 103 to be twisted off. Therefore, as shown in fig. 2, in the present embodiment, a limiting hole 114 is further disposed on the first fixing member 11. The limiting hole 114 is disposed corresponding to the barrel opening 1021 of the lens barrel 102. At this time, the fixing rod may be used to simultaneously pass through the limiting hole 114 and the barrel opening 1021 to prevent the relative rotation of the first fixing member 11 and the lens fixing barrel 102. Since the fixing rod is subjected to torsion, damage to the fastener 103 can be avoided. In this embodiment, the limiting hole 114 is a circular hole structure.

Alternatively, as shown in fig. 4, a support step 112 abutting against a fixed barrel step 1022 of the lens fixed barrel 102 is provided in the first fixing member 11, so that it is possible to place the lens fixed barrel 102 in the first fixing member 11 with great ease so that the first fixing member 11 supports the lens fixed barrel 102. Of course, in other embodiments, other support steps may be provided to abut other step structures in the lens holding cylinder 102.

Optionally, as shown in fig. 2, the fixing mechanism 1 further comprises a second fixing member 12 connected to the first fixing member 11, and the second fixing member 12 is disposed on the external platform. Specifically, a third mounting hole 122 is provided on the second fixing member 12, and the first connecting member can pass through the third mounting hole 122 to fixedly mount the second fixing member 12 to the external platform. In this embodiment, the first fixing member 11 and the second fixing member 12 are each a cylindrical structure. A disc-shaped base is further provided on the second fixing member 12, and a third mounting hole 122 is provided on the base. Optionally, the number of the third mounting holes 122 is 3, and each of the third mounting holes is a threaded hole, and the first connecting member is a bolt.

Alternatively, the first fixing member 11 and the second fixing member 12 are detachably coupled. As shown in fig. 2, in the present embodiment, the first fixing member 11 is a cylindrical structure with a variable diameter, and the lower portion thereof can be fitted in the through hole of the second fixing member 12. A first mounting hole 113 is formed in the first fixing member 11, a corresponding second mounting hole 121 is formed in the second fixing member 12, and a second connecting member can be disposed through the second mounting hole 121 and the first mounting hole 113, thereby connecting the first fixing member 11 and the second fixing member 12. Optionally, each of the first mounting hole 113 and the second mounting hole 121 is provided with 3 mounting holes, and is a threaded hole, and the second connecting member is a screw.

To more clearly show the function of the lens disassembling jig, the following description is provided for the use of the lens disassembling jig:

1. before disassembly, the machine-meter screw 105 connecting the object distance adjusting ring 101 and the inner adjusting ring 104 is unscrewed;

2. the lens fixing cylinder 102 is mounted on the fixing mechanism 1 to prevent the lens fixing cylinder 102 from rotating around the axis of the lens to be disassembled, and the rotating member 2 is mounted on the object distance adjusting ring 101.

3. an acting force is applied to the handle 3, so that the rotating part 2 rotates and drives the object distance adjusting ring 101 to rotate around the axis of the lens to be disassembled, and the object distance adjusting ring 101 is separated from the inner adjusting ring 104 to complete the disassembly of the object distance adjusting ring 101. The overall structure after disassembly is shown in fig. 6.

In summary, the object distance adjusting ring 101 can be conveniently rotated relative to the inner adjusting ring 104 by the fixing mechanism 1 and the rotating member 2, so that the object distance adjusting ring 101 can be disassembled from the lens to be disassembled. Simultaneously, can provide the arm of force when rotating 2 drives the thing apart from adjustable ring 101 and rotate through setting up handle 3, form laborsaving lever, make to disassemble more easily, efficiency is higher.

Example two

The embodiment provides a lens disassembling jig. As shown in fig. 7, the lens disassembling jig includes a fixing mechanism 1, a rotating member 2, and a handle 3. Compared with the first embodiment, the main difference is that the fixed mechanism 1 and the rotating member 2 are arranged at different positions.

Specifically, the fixing mechanism 1 is mounted on an object distance adjusting ring 101 of the lens to be disassembled, and is used for preventing the object distance adjusting ring 101 from rotating around the axis of the lens to be disassembled. The rotating part 2 is installed on the lens barrel assembly of the lens to be disassembled and is used for driving the inner adjusting ring 104 in the lens barrel assembly to rotate around the axis of the lens to be disassembled. The handle 3 is fixedly connected with the rotating member 2 and is used for providing a moment arm for the rotation of the inner adjusting ring 104. The structures of the fixing mechanism 1 and the rotating member 2 in this embodiment can be appropriately adjusted as required to achieve the rotation of the inner adjusting ring 104 and the fixing of the object distance adjusting ring 101.

According to the arrangement, the inner adjusting ring 104 can rotate relative to the object distance adjusting ring 101, so that the inner adjusting ring 104 is separated from the object distance adjusting ring 101.
