These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0034] This embodiment provides a lens coding jig, which is suitable for the same type of lenses with different coding area positions. When coding the same type of lenses with different coding area positions, there is no need to adjust the position of the laser etching equipment or the lens coding jig, which saves debugging time and improves coding efficiency.

[0035] Specifically, if Figures 1-4 As shown, the lens includes a head 10 and a body 20 connected to the head 10. Among the same type of lenses, some lenses are provided with a coding area 30 on the head 10, and some lenses are provided with a coding area 30 at one end of the body 20 close to the head 10. The lens coding fixture includes a fixture body 100, and the fixture body 100 is provided with a positive fixing space 110 ( Figure 1 The part in the solid line frame) and the reverse fixed space 120 ( Figure 1 The forward fixing space 110 is used to fix the lens of the body 20 provided with the coding area 30, and the reverse fixing space 120 is used to fix the lens of the head 10 provided with the coding area 30. The forward fixing space 110 and the reverse fixing space 120 are partially overlapped, so that when the lens is fixed by the forward fixing space 110 and the lens is fixed by the reverse fixing space 120, the position of the coding area 30 relative to the fixture body 100 is the same.

[0036] The process of using this lens coding fixture to code the lens is as follows:

[0037] Place the lens coding jig on the coding workbench and adjust its flatness;

[0038] According to the position of the coding area 30 on the lens to be processed, it is installed in the forward fixed space 110 or the reverse fixed space 120. For example, the coding area 30 on the lens to be processed is located on the body 20 (see Figure 2 ), the lens is installed in the positive fixed space 110;

[0039] Adjust the position of the laser etching device so that the coding module of the laser etching device is aligned with the coding area 30. After adjusting the position of the laser etching device, start coding.

[0040] When it is necessary to switch to coding the lens of the coding area 30 located at the head 10 (see Figure 3 ), it is only necessary to install the lens in the reverse fixed space 120, and the coding operation can be started without adjusting the position of the lens coding fixture or laser etching equipment, which saves the time of debugging the equipment and greatly improves the coding efficiency of the lens.

[0041] Further, see Figure 1In this embodiment, a first head fixing groove 101 and a second head fixing groove 102 for fixing the head 10 are provided in the middle of the fixture body 100. The first head fixing groove 101 and the second head fixing groove 102 are arranged adjacent to each other and are connected through a connecting groove 103. The connecting groove 103 is used to fix part of the body 20. Body fixing grooves 104 are symmetrically provided on both sides of the first head fixing groove 101 and the second head fixing groove 102. The body fixing grooves 104 are connected to their corresponding first head fixing grooves 101 or second head fixing grooves 102. The first head fixing groove 101, the connecting groove 103, the second head fixing groove 102 and the body fixing groove 104 that are sequentially connected along the first direction form a forward fixing space 110. The second head fixing groove 102, the connecting groove 103, the first head fixing groove 101 and the body fixing groove 104 that are sequentially connected along the second direction form a reverse fixing space 120. Such an arrangement has a certain anti-foolproof performance, such as Figure 4 As shown, if the head portion 10 of the lens is installed upward, if the head portion 10 is fixed in the second head fixing groove 102 , the body portion 20 cannot be fixed.

[0042] The first direction is opposite to the second direction. In this embodiment, the first direction is a vertically downward direction, and the second direction is a vertically upward direction.

[0043] Further, see Figure 2 and Figure 3 For ease of understanding, we define lenses with a coding area 30 on the head 10 as a first-class lens, and lenses with a coding area 30 on the body 20 as a second-class lens. The distance a between the coding area 30 on the first-class lens and the wall of the second head fixing slot 102 near the connecting slot 103 is a first distance, and the distance b between the coding area 30 on the second-class lens and the wall of the second head fixing slot 102 near the connecting slot 103 is a second distance, which is equal to the first distance. Furthermore, the first head fixing slot 101 and the second head fixing slot 102 have the same dimensions, and the two body fixing slots 104 have the same dimensions. This arrangement results in a symmetrical structure between the first head fixing slot 101, the connecting slot 103, the second head fixing slot 102, and the two body fixing slots 104, facilitating processing.

[0044] Furthermore, when using the forward fixing space 110 to install the lens, the head 10 can be made to abut against the groove wall of the first head fixing groove 101 close to the connecting groove 103; and when using the reverse fixing space 120 to install the lens, the head 10 can be made to abut against the groove wall of the second head fixing groove 102 close to the connecting groove 103, thereby reducing the difficulty of installing the lens.

[0045] It is worth noting that the diameter of the head 10 is larger than the diameter of the body 20, the sizes of the first head fixing groove 101 and the second head fixing groove 102 match the head 10, and the sizes of the body fixing groove 104 and the connecting groove 103 match the body 20. This arrangement can not only improve the fixing effect of the lens, but also has a certain degree of fool-proofness.

[0046] Optionally, in this embodiment, the length of the lens in the axial direction is 16 mm-18 mm, and the length of the forward fixing space 110 and the length of the reverse fixing space 120 are both 18 mm.

[0047] Optionally, in this embodiment, the width of the first head fixing groove 101 and the second head fixing groove 102 is 1 to 1.5 times the diameter of the head 10 . Such an arrangement has a better fixing effect on the head 10 .

[0048] Optionally, the width of the connecting groove 103 along the first direction is 0.5 mm-1 mm, which is convenient for processing. The size should not be too large to avoid affecting the positioning of the coding area 30.

[0049] Further, see Figure 1 In one possible embodiment, first escape grooves 130 are provided on both sides of the first head fixing groove 101, communicating therewith. These first escape grooves 130 are used to remove the lens. The provision of these first escape grooves 130 facilitates lens removal and improves lens coding efficiency. Optionally, the length c of the first escape grooves 130 is 4 mm to 5 mm.

[0050] Further, see Figure 1 In another possible embodiment, second escape grooves 140 are provided on both sides of the second head fixing groove 102, communicating therewith. The second escape grooves 140 are used to remove the lens. The provision of the second escape grooves 140 facilitates lens removal and improves lens coding efficiency. Optionally, the length d of the second escape grooves 140 is 4 mm to 5 mm.

[0051] In this embodiment, first avoidance grooves 130 connected to the first head fixing groove 101 are provided on both sides thereof, and second avoidance grooves 140 connected to the second head fixing groove 102 are provided on both sides thereof. This arrangement makes it convenient to take the lens regardless of whether it is installed in the forward fixing space 110 or the reverse fixing space 120.

[0052] Optionally, continue with Figures 1-4 The fixture body 100 is provided with an anti-fool mark 150, which is arranged opposite to the body fixing groove 104. The anti-fool mark 150 is used to mark the installation direction of the lens.

[0053] For example, in this embodiment, when the head 10 faces the foolproof mark 150, the lens is installed in the positive fixing space 110, and when the body 20 faces the foolproof mark 150, the lens is installed in the reverse fixing space 120. In this way, the foolproof mark 150 guides the installation of the lens, improves the installation efficiency of the lens, and further improves the coding efficiency of the lens.

[0054] Of course, the lens can also be installed in the reverse fixed space 120 when the head 10 faces the anti-fool mark 150, and in the forward fixed space 110 when the body 20 faces the anti-fool mark 150. It can be set as needed.

[0055] Optionally, the fool-proof mark 150 can be the name of the fixture, or a color mark, etc., and can be set according to actual needs. This application does not make any specific limitations.

[0056] Furthermore, if Figure 5 As shown, the side of the jig body 100 facing away from the forward fixing space 110 and the reverse fixing space 120 is provided with an air-avoidance groove 160 and a supporting surface 170 surrounding the air-avoidance groove 160. The jig body 100 is placed on the coding workbench via the supporting surface 170. The provision of the air-avoidance groove 160 reduces the contact area between the jig body 100 and the coding workbench, thereby improving the flatness of the jig body 100 and improving the coding quality.

[0057] Optionally, the depth of the air-avoiding groove 160 may be 0.5 mm-1 mm, and the width e of the supporting surface 170 may be 3 mm-4 mm.

[0058] Exemplarily, the depth of the air avoidance groove 160 can be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm or 1mm, and the width of the supporting surface 170 can be 3mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm or 3.5mm, etc., which can be set according to actual needs and is not specifically limited in this application.

[0059] Optionally, the material of the fixture body 100 may be polyetheretherketone (PEEK), which is lightweight and easy to carry.

[0060] 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.
