DETAILED DESCRIPTION

[0026] In the following description, numerous specific details are provided in order to provide a thorough understanding of the present application. One of ordinary skill in the art will realize, however, that the application can be practiced without one or more of these details. In other instances, well-known structures and functions have not been described in detail in order not to unnecessarily obscure the present application.

[0027] In order to thoroughly understand the embodiments of the present application, detailed structures will be proposed in the following description. Obviously, the implementation of the embodiments of the present application is not limited to the special details familiar to those skilled in the art. The preferred embodiments of the present application are described in detail as follows, however, in addition to these detailed descriptions, the present application can also have other embodiments.

[0028] In the embodiments of the present application, a lens mounting positioner is provided. The lens mounting positioner can be used for mounting and positioning of a lens and a lens clamp. In combination with reference to Fig. 1 , Fig. 4 and Fig. 6The lens mounting positioner 10 can include a main body 110, in which a first mounting cavity 1101 and a second mounting cavity 1102 are formed. The shape of the first mounting cavity 1101 can be set according to the shape of the lens 20, and the shape of the second mounting cavity 1102 can be set according to the shape of the lens clamp 30. The first mounting cavity 1101 has a first positioning surface 1111, and at least part of the structure of the lens 20 can be mounted in the first mounting cavity 1101 and abut against the first positioning surface 1111 to position the lens 20 at a first position. The second mounting cavity 1102 can have a second positioning surface 1121, and at least part of the structure of the lens clamp 30 can be mounted in the second mounting cavity 1102 and abut against the second positioning surface 1121 to position the lens clamp 30 at a second position. The first mounting cavity 1101 and the second mounting cavity 1102 are arranged such that the lens 20 positioned at the first position partially penetrates the lens clamp 30 positioned at the second position. That is, the lens 20 is limited at the first position by abutting against the first positioning surface 1111, and the lens clamp 30 is limited at the second position by abutting against the second positioning surface 1121. In this way, the relative position of the lens 20 and the lens clamp 30 can be controlled by reasonable arrangement of the first positioning surface 1111 and the second positioning surface 1121. The lens 20 can have one part of the structure located in the first mounting cavity 1101 and another part of the structure located in the second mounting cavity 1102. The lens clamp 30 has a clamping hole, and the part of the lens 20 located in the second mounting cavity 1102 is in the lens clamp 30 (specifically, penetrates the clamping hole) and is used for mounting connection with the lens clamp 30.

[0029] When mounting the lens 20 and the lens clamp 30, the lens 20 can be inserted into the first mounting cavity 1101 until the lens 20 abuts against the first positioning surface 1111, and then the lens clamp 30 is mounted into the second mounting cavity 1102 until the lens clamp 30 abuts against the second positioning surface 1121, so as to determine the relative position of the lens 20 and the lens clamp 30. On this basis, the lens 20 and the lens clamp 30 are connected and fixed (which can be achieved by using fasteners 330, etc.), so as to achieve the connection and fixation of the lens 20 and the lens clamp 30. Then the lens mounting positioner 10 can be removed, and the lens clamp 30 drives the lens 20 to perform AA adjustment of the lens 20 and subsequent dispensing operations.

[0030] The lens mounting positioner 10 provided in the application can be used as an auxiliary device in the mounting process of the lens 20 and the lens clamp 30. The first positioning surface 1111 can limit the position of the lens 20, and the second positioning surface 1121 can limit the position of the lens clamp 30, that is, the lens 20 is limited to the first position and the lens clamp 30 is limited to the second position, so as to limit the relative position of the lens 20 and the lens clamp 30, thereby facilitating the subsequent mounting of the lens 20 and the lens clamp 30. In this way, the relative position between the lens clamp 30 and the lens 20 can be ensured to be accurate through the setting of the lens mounting positioner 10, that is, the axis of the lens 20 can be ensured to be consistent with the axis of the lens clamp 30. When multiple groups of lenses 20 and lens clamps 30 of the same type need to be mounted, the first positioning surface 1111 can limit each lens 20 to the first position and each lens clamp 30 to the second position, so that the positions of different lenses 20 and lens clamps 30 are consistent, and the positions of each group of lenses 20 and lens clamps 30 do not need to be adjusted after mounting, thereby improving the mounting efficiency of the lenses 20 and the lens clamps 30 and ensuring the consistency of the subsequent mounting effect.

[0031] It can be understood that the lens mounting positioner 10 is used as an auxiliary device in the mounting process of the lens 20 and the lens clamp 30. The position of the lens 20 and the position of the lens clamp 30 are limited by the lens mounting positioner 10, which eliminates the need for positioning structures such as mounting cavities provided on the lens clamp 30, so that the size of the lens clamp 30 can be smaller, thereby facilitating the subsequent dispensing process.

[0032] For example, in combination with the first mounting cavity 1101, the first positioning surface 1111 can be provided on the first positioning table 1110, the lens 20 can include a barrel 210 and a mounting boss 220 provided on the outer periphery of the barrel 210, the barrel 210 can be inserted into the inside of the first positioning table 1110, and the mounting boss 220 can abut against the first positioning surface 1111. Fig. 3 、 Fig. 4 、 Fig. 5 and Fig. 6 For example, in combination with the first mounting cavity 1101, the first positioning surface 1111 can be provided on the first positioning table 1110, the lens 20 can include a barrel 210 and a mounting boss 220 provided on the outer periphery of the barrel 210, the barrel 210 can be inserted into the inside of the first positioning table 1110, and the mounting boss 220 can abut against the first positioning surface 1111.

[0033] For example, in combination with the first mounting cavity 1101, the first positioning surface 1111 can be provided on the first positioning table 1110, the lens 20 can include a barrel 210 and a mounting boss 220 provided on the outer periphery of the barrel 210, the barrel 210 can be inserted into the inside of the first positioning table 1110, and the mounting boss 220 can abut against the first positioning surface 1111. Fig. 4 ,Fig. 5 and Fig. 6 The first positioning platform 1110 can have a first positioning side surface 1112 connected with the first positioning surface 1111, the first positioning side surface 1112 being configured to abut against the outer circumferential wall of the barrel 210. The inner space enclosed by the first positioning side surface 1112 constitutes a part of the first mounting cavity 1101, and the barrel 210 is inserted into the space. The outer circumferential wall of the barrel 210 can abut against the first positioning side surface 1112. The first positioning platform 1110 is annular, and the axis of the first positioning platform 1110 can coincide with the axis of the lens 20. In this way, the position of the lens 20 in the radial direction is limited by the first positioning side surface 1112, and the position of the axis of the lens 20 is determined so as to better coincide with the axis of the lens holder 30. It can be understood that the length of the first positioning side surface 1112 in the axial direction of the first positioning platform 1110 affects the positioning of the lens 20, i.e., the positioning of the axis of the lens 20. The longer the length of the first positioning side surface 1112, the larger the contact area with the lens 20, and accordingly, the axis of the lens 20 can better coincide with the axis of the lens holder 30. Conversely, the shorter the length of the first positioning side surface 1112, the smaller the contact area with the lens 20, and the more difficult it is to accurately position the axis of the lens 20, i.e., more difficult to coincide with the axis of the lens holder 30. Exemplarily, the length of the first positioning side surface 1112 in the axial direction of the first positioning platform 1110 can be greater than the length of the barrel 210. Exemplarily, the inner edge of the first positioning surface 1111 can be formed with an inclined guide structure to facilitate the insertion of the lens 20. In an embodiment not shown, the first positioning side surface can be spaced apart from the outer circumferential wall of the barrel.

[0034] Exemplarily, in combination with reference to Fig. 1 , Fig. 5 , Fig. 6 and Fig. 7The second positioning table 1120 can be connected with the first positioning surface 1111 and extend to the second mounting cavity 1102. An end surface of the second positioning table 1120 away from the first positioning table 1110 can form a second positioning surface 1121. The second positioning surface 1121 can be understood as a cavity bottom of the second mounting cavity 1102. The second positioning table 1120 can be an annular table with an inner diameter greater than that of the first positioning table 1110. A space enclosed by the first positioning table 1110 and a space enclosed by the second positioning table 1120 together constitute the first mounting cavity 1101. During installation, the lens clamp 30 is installed into the second mounting cavity 1102 until the lens clamp 30 abuts against the second positioning surface 1121. The second positioning surface 1121 can define the position of the lens clamp 30 in the axial direction. In this way, the lens clamp 30 is better defined in the second position by the second positioning surface 1121, so as to ensure accurate fixing of the relative position between the lens clamp 30 and the lens 20, and the structure is simple and the positioning process of the lens clamp 30 is simple and efficient.

[0035] For example, in combination with reference to Fig. 1 , Fig. 3 , Fig. 6 and Fig. 7 , the main body 110 can further include a third positioning table 1130 disposed on a side of the second positioning table 1120 away from the first positioning table 1110. A space enclosed by the third positioning table 1130 constitutes the second mounting cavity 1102. The third positioning table 1130 can have a second positioning side surface 1131 connected with the second positioning surface 1121, and the second positioning side surface 1131 can be used to fit the outer peripheral wall of the clamping portion 310 of the lens clamp 30. The lens clamp 30 can include a clamping portion 310 for clamping the lens 20 and a connecting portion 320 connected with the clamping portion 310. The clamping portion 310 can be installed on the inner side of the third positioning table 1130, and the outer peripheral wall of the clamping portion 310 can fit the second positioning side surface 1131. The clamping portion 310 can be annular, and the lens 20 has a clamping fixing surface 230, and the clamping portion 310 is sleeved on the outer periphery of the clamping fixing surface 230. The third positioning table 1130 can be an annular table with an inner diameter greater than that of the second positioning table 1120. That is, in the embodiment provided with the first positioning table 1110 and the second positioning table 1120, the inner diameters of the first positioning table 1110, the second positioning table 1120 and the third positioning table 1130 increase in turn. The first positioning table 1110, the second positioning table 1120 and the third positioning table 1130 can be coaxially arranged. The second positioning side surface 1131 can define the position of the lens clamp 30 in the radial direction, determine the position of the axis of the lens clamp 30, and make the axis of the lens clamp 30 better coincide with the axis of the lens 20.

[0036] For example, in combination with reference to Fig. 2 ,Fig. 5 and Fig. 7 The third positioning table 1130 can be ring-shaped and open on one side, and the first extension wall 1140 and the second extension wall 1150 can be oppositely arranged on both sides of the opening, so that the connecting portion 320 of the lens clamp 30 positioned at the second position passes out of the gap formed by the opening, the first extension wall 1140 and the second extension wall 1150. The distance between the first extension wall 1140 and the second extension wall 1150 is matched with the size of the connecting portion 320. The connecting portion 320 has a first side wall and a second side wall opposite to each other. The first side wall is in abutment with the first extension wall 1140, and the second side wall is in abutment with the second extension wall 1150. The first extension wall 1140 and the second extension wall 1150 can limit the rotation of the connecting portion 320 in the circumferential direction, limit the position of the connecting portion 320, that is, limit the position of the lens clamp 30 in the circumferential direction, and further ensure the accurate fixing of the relative position between the lens clamp 30 and the lens 20.

[0037] For example, in combination with reference to Fig. 2 and Fig. 5 The lens mounting positioner 10 can further include a screwing member (not shown in the figure), which can pass through the first extension wall 1140 so that the connecting portion 320 passing out of the gap can be clamped between the screwing member and the second extension wall 1150, or the screwing member can pass through the second extension wall 1150 so that the connecting portion 320 passing out of the gap can be clamped between the screwing member and the first extension wall 1140. The first extension wall 1140 or the second extension wall 1150 can be provided with a through hole 1141, and the screwing member can pass through the through hole 1141. After the lens clamp 30 is installed into the second mounting cavity 1102, the screwing member can be screwed to better clamp the connecting portion 320 between the screwing member and the corresponding first extension wall 1140 or second extension wall 1150, and the position of the connecting portion 320 is more stable, that is, the position of the lens clamp 30 is more stable.

[0038] For example, in combination with reference to Fig. 5 and Fig. 7 The third positioning table 1130 can be provided with a avoiding opening 1132 for avoiding the fastener 330 arranged on the clamping portion 310. The avoiding opening 1132 can expose the fastener 330 arranged on the clamping portion 310. During installation, after the lens 20 is installed into the first position and the lens clamp 30 is installed into the second position, the connection between the lens 20 and the lens clamp 30 can be fixed by the fastener 330, so that the lens 20 is more stably connected to the lens clamp 30. For example, the fastener 330 can be a top screw structure.

[0039] According to another aspect of the present application, in combination with reference to Fig. 1 , Fig. 2 and Fig. 7The lens clamp 30 is provided with a connecting portion 320 and a clamping portion 310, the clamping portion 310 is annular, the connecting portion 320 is connected to one side of the clamping portion 310 and extends away from the one side of the clamping portion 310, and the clamping portion 310 is used to abut the second positioning surface 1121 of any one of the lens mounting positioners 10, so as to position the lens clamp 30 to the second position. The lens clamp 30 arranged in this way is limited in the second position under the action of the lens mounting positioner 10, and the axial line of the lens 20 can be better guaranteed to be consistent with the axial line of the lens clamp 30. When it is required to mount multiple lenses 20 and lens clamps 30 of the same type, the clamping positions of different lenses 20 and lens clamps 30 are consistent, and it is not required to adjust the positions of each group of lenses 20 and lens clamps 30 after mounting, so that the mounting efficiency of the lenses 20 and the lens clamps 30 is higher.

[0040] Exemplarily, referring to Fig. 1 The connecting portion 320 can be provided with a positioning hole 3210 for being connected to the adjusting assembly. The connecting portion 320 is connected to the adjusting assembly and moves the lens clamp 30 under the driving of the adjusting assembly, so as to adjust the position of the lens 20, that is, to perform AA adjustment on the lens 20.
