Description

Technical Field

[0001] The utility model relates to the technical field of lenses, in particular to a lens dispensing fixture. Background Art

[0002] At present, for optical zoom lenses and autofocus lenses, during use, it is necessary to drive the lens assembly through the cooperation of a transmission screw and a transmission nut to achieve changes in optical performance. Usually, a driving device is used to drive the transmission screw to rotate, so that the transmission nut and the lens assembly on the transmission screw generate displacement. Through the transmission nut, the rotational motion of the transmission screw is converted into the linear motion required by the lens assembly.

[0003] The transmission nut generally includes a nut body. The nut body is provided with a threaded hole that cooperates with the transmission screw, and a connection hole that cooperates with the connection bracket of the lens assembly through a pin. An installation space is provided on the connection bracket of the lens assembly. The part of the nut body with the connection hole is installed in the installation space. Installation holes are provided on the opposite two side walls of the connection bracket of the lens assembly close to the installation space. The pin sequentially passes through one installation hole, the connection hole, and the other installation hole to connect the transmission nut to the connection bracket of the lens assembly. Moreover, a dispensing port communicating with the connection hole is provided on the nut body, and glue is dispensed through the dispensing port to fix the pin.

[0004] When dispensing the pin, the lens assembly is generally fixed in the fixture. The traditional lens fixture has a fixing groove on the fixture body that matches the outer shape of the lens assembly. The lens assembly is directly placed in the fixing groove. After the lens assembly is fixed, the lens assembly is in a horizontal state (the axis of the lens assembly is perpendicular to the horizontal plane), and the transmission nut connected to the lens assembly is in a vertical state (the transmission nut is parallel to the axis of the lens assembly). The dispensing port of the pin is placed inside the transmission nut, and the curing light of the glue in the vertical direction cannot directly irradiate the glue at the dispensing port, easily resulting in incomplete curing of the glue, causing the pin to fall off easily, and seriously affecting the quality of the lens.

[0043] Embodiment 1

[0044] Figure 1 FIG. 16 is a schematic structural diagram of a lens 10 in the prior art. The lens 10 includes a lens assembly 11 and a transmission nut 12 provided on the lens assembly 11. The transmission nut 12 is provided with a connection hole for a pin to pass through, and a pin dispensing port 13 communicating with the connection hole. After the pin passes through the connection hole to connect the transmission nut 12 with the lens 10 assembly, glue will be dropped into the connection hole through the pin dispensing port 13 to fix the pin and prevent the pin from falling off.

[0045] Before dispensing glue at the pin dispensing port 13 and curing the glue, the lens 10 needs to be fixed first. After fixing the lens 10 with a traditional lens fixture, the placement state of the lens 10 is as follows Figure 1 shown, that is, the lens assembly is in a horizontal state, the axis of the lens assembly extends in the vertical direction, the drive nut 12 is in a vertical state, and the pin dispensing port 13 is placed inside the drive nut 12. Figure 1 The direction indicated by the arrow in Figure 1 is the irradiation direction of the glue curing light, that is, the glue curing light will irradiate the lens 10 in the vertical direction. However, after the lens 10 is placed like this, the pin dispensing port 13 does not face the glue curing light. Therefore, the glue curing effect is not good, and the problem of incomplete glue curing is likely to occur, resulting in easy detachment of the pin, seriously affecting the quality of the lens 10.

[0046] Based on the above problems, this embodiment provides a lens dispensing fixture, which changes the placement direction of the pin dispensing port 13, so that the glue curing light can directly irradiate the glue in the pin dispensing port 13, improving the glue curing effect, reducing the risk of pin detachment, and thus improving the quality of the lens 10.

[0047] Specifically, as shown in Figures 2 - 6 shown, the lens dispensing fixture includes a base 100 and a pressing plate 200. Among them, the base 100 includes a bottom plate 110 and a lens fixing portion 120 provided on the bottom plate 110. The lens fixing portion 120 is provided with a fixing groove 121. The lens 10 is installed in the fixing groove 121 with its axis parallel to the plate surface of the bottom plate 110. The drive nut 12 abuts against the bottom wall of the fixing groove 121, and the pin dispensing port 13 is arranged upward. The pressing plate 200 is arranged on the bottom plate 110. The pressing plate 200 includes a pressing portion 210 extending along the length direction of the lens fixing portion 120. The pressing portion 210 is provided with a pressing arm 211. The pressing arm 211 presses against the upper side of the drive nut 12 to press the drive nut 12 against the bottom wall of the fixing groove 121.

[0048] The lens dispensing fixture provided in this embodiment can fix the lens 10 with the pin dispensing port 13 facing upward, so that the glue curing light can directly irradiate the glue in the pin dispensing port 13, improving the glue curing effect, reducing the risk of pin detachment, and thus improving the quality of the lens 10. And by setting the pressing arm 211 on the pressing portion 210 to press the drive nut 12 against the bottom wall of the fixing groove 121, the risk of the drive nut 12 tilting due to problems such as improper installation can be reduced, improving the reliability of the pin dispensing port 13 facing upward after the lens 10 is fixed, enabling the glue curing light to effectively cure the glue in the pin dispensing port 13, improving the glue curing effect, reducing the risk of pin detachment, and thus improving the quality of the lens 10.

[0049] In this embodiment, the extending direction of the lens fixing portion 120 is the length direction of the bottom plate 110 ( Figure 4 The axial direction of the lens 10 is the width direction of the bottom plate 110 ( Figure 4 The direction indicated by the X-axis), the glue curing light is along the vertical direction ( Figure 4 The lens 10 is illuminated by the light (in the direction indicated by the Z axis).

[0050] The steps of fixing the lens 10 using the lens dispensing fixture are as follows:

[0051] First, the lens 10 is placed in the fixing groove 121 ; then, the pressing plate 200 is placed on the bottom plate 110 ; thereafter, the pressing plate 200 is pushed until the pressing arm 211 is located above the transmission nut 12 and presses against the transmission nut 12 .

[0052] It is worth noting that, in general, the pressing plate 200 is made of metal material and is heavy. Therefore, the pressing plate 200 can be pressed on the bottom plate 110 under the action of its own gravity and ensure that the pressing arm 211 can reliably press the transmission nut 12 .

[0053] It is worth noting that when installing the pressing plate 200 , it should be ensured that the pressing arm 211 does not block the pin dispensing port 13 .

[0054] Optionally, continue to see Figure 4 In this embodiment, the fixing groove 121 includes an upper opening and a side opening. The lens 10 is installed in the fixing groove 121 through the upper opening, and the pressing arm 211 extends into the fixing groove 121 through the side opening and presses against the transmission nut 12. The upper opening is provided to facilitate the installation of the lens 10, and the side opening is provided to facilitate the contact between the pressing arm 211 and the transmission nut 12. The fixing groove 121 has a reasonable structure, is conducive to saving space, and is also easy to process.

[0055] Furthermore, in this embodiment, part of the bottom wall of the fixing groove 121 is the plate surface of the bottom plate 110, and the driving nut 12 abuts against the plate surface of the bottom plate 110. In this way, the bottom plate 110 can be used to ensure that the driving nut 12 is placed horizontally, and no additional structure needs to be designed, which reduces the processing difficulty of the fixing groove 121, is conducive to improving the processing efficiency of the lens dispensing fixture, and reducing the processing cost.

[0056] Of course, in other embodiments, the structure of the fixing groove 121 can also be set to other structures. For example, the fixing groove 121 is formed by the top of the lens fixing portion 120 along the vertical direction ( Figure 4 The fixing groove 121 is formed by the side wall of the lens fixing portion 120 along a direction perpendicular to the length of the lens fixing portion 120 (in the direction shown by the Z axis in the middle). Figure 4A concave shape is formed in the direction shown by the X-axis in the figure, etc., which can be set according to actual needs, and the present application does not make specific limitations.

[0057] Furthermore, in order to improve the dispensing efficiency and the glue curing efficiency, a lens dispensing fixture can be set to fix multiple lenses 10 at the same time. Specifically, in this embodiment, there are multiple lens fixing parts 120. The multiple lens fixing parts 120 are arranged in parallel at intervals. Multiple fixing grooves 121 are provided on each lens fixing part 120, and the multiple fixing grooves 121 are arranged at intervals along the length direction of the lens fixing part 120. There are multiple pressing parts 210. The multiple pressing parts 210 are arranged in parallel at intervals. The pressing parts 210 are arranged in one-to-one correspondence with the lens fixing parts 120. Multiple pressing arms 211 are provided on each pressing part 210, and the pressing arms 211 are arranged in one-to-one correspondence with the fixing grooves 121.

[0058] Optionally, in this embodiment, the multiple lens fixing parts 120 are arranged in parallel at intervals along the width direction of the bottom plate 110 ( Figure 4 the direction shown by the X-axis in the figure), and the multiple pressing parts 210 are also arranged in parallel at intervals along the width direction of the bottom plate 110 ( Figure 4 the direction shown by the X-axis in the figure). The lens fixing parts 120 extend along the length direction of the bottom plate 110 ( Figure 4 the direction shown by the Y-axis in the figure).

[0059] Furthermore, continue to refer to Figure 2 and Figure 4 , among the opposite two sides of the bottom plate 110 along the direction perpendicular to the length direction of the lens fixing part 120, one side is provided with the lens fixing part 120, and the other side is provided with a baffle 130 parallel to the lens fixing part 120. The multiple pressing parts 210 are placed between the baffle 130 and the lens fixing part 120. The lens fixing part 120 and the baffle 130 on both sides of the bottom plate 110 limit the pressing plate 200. On the one hand, it has a certain guiding effect on the installation of the pressing plate 200; on the other hand, it can limit the movement of the pressing plate 200 to a certain extent, improving the reliability of the work of the pressing arm 211 pressing the transmission nut 12.

[0060] Optionally, a handle 230 can be set on the pressing plate 200. The staff can carry or move the pressing plate 200 through the handle 230. The setting of the handle 230 provides convenience for the carrying and moving of the pressing plate 200.

[0061] Furthermore, continue to refer to Figure 4 and Figure 6, a positioning post 212 is provided on the pressing portion 210, and a positioning groove 111 is provided on the bottom plate 110. The positioning post 212 is inserted into the positioning groove 111. Through the cooperation of the positioning post 212 and the positioning groove 111, the connection strength between the pressing plate 200 and the bottom plate 110 can be improved, thereby improving the reliability of the pressing arm 211 on the pressing plate 200 to press the transmission nut 12 to work.

[0062] Optionally, in order to improve the installation stability of the pressing plate 200, after the positioning post 212 is inserted into the positioning groove 111, the bottom of the pressing plate 200 is closely attached to the bottom plate 110.

[0063] Exemplarily, in a possible embodiment, the length of the positioning post 212 is less than or equal to the depth of the positioning groove 111, that is, the positioning post 212 can be completely inserted into the positioning groove 111, and the bottom of the pressing portion 210 is the bottom of the entire pressing plate 200. After the positioning post 212 is inserted into the positioning groove 111, the bottom of the pressing portion 210 is closely attached to the bottom plate 110.

[0064] Optionally, the positioning post 212 can be a press-in type ball head plunger. The press-in type ball head plunger includes a plunger tube and a ball head telescopically arranged in the plunger tube. The end of the plunger tube abuts against the bottom plate 110, and the ball head is inserted into the positioning groove 111. That is, during the process of moving the pressing plate 200, the ball head is pressed into the plunger tube. After the pressing plate 200 moves in place, the ball head is inserted into the positioning groove 111. With such a setting, during the process of moving the pressing plate 200 to make the pressing arm 211 press the transmission nut 12, the movement of the pressing plate 200 can be made more stable.

[0065] Optionally, multiple positioning posts 212 can be provided, and each positioning post 212 corresponds to at least one positioning groove 111. Setting multiple positioning posts 212 can further improve the connection strength between the pressing plate 200 and the bottom plate 110.

[0066] In this embodiment, each positioning post 212 corresponds to two positioning grooves 111. One positioning groove 111 is used to position the initial position of the pressing plate 200, and the other positioning groove 111 is used to position the end position of the pressing plate 200. The initial position of the pressing plate 200 is the position where the pressing plate 200 is first placed on the bottom plate 110, and the end position of the pressing plate 200 is the position of the pressing plate 200 when the pressing arm 211 presses against the transmission nut 12.

[0067] Further, the pressing plate 200 further includes two oppositely arranged connecting beams 220. Two ends of the pressing portion 210 are respectively connected to the two connecting beams 220. A first guide shaft 221 is provided on the connecting beam 220, and a long strip hole 112 corresponding to the first guide shaft 221 is provided on the bottom plate 110. The long strip hole 112 extends along the length direction of the lens fixing portion 120, and the first guide shaft 221 is slidably connected in the long strip hole 112. With such a setting, during the process of moving the pressing plate 200 so that the pressing arm 211 can press the transmission nut 12 (i.e., during the process of installing the pressing plate 200), the cooperation between the first guide shaft 221 and the long strip hole 112 can guide the movement of the pressing plate 200, which is beneficial to improving the installation efficiency of the pressing plate 200.

[0068] Optionally, a plurality of first guide shafts 221 can be provided, and the first guide shafts 221 and the long strip holes 112 are arranged in one-to-one correspondence. By providing a plurality of first guide shafts 221 to cooperate with the long strip holes 112, the smoothness of the movement of the pressing plate 200 can be improved.

[0069] In this embodiment, two first guide shafts 221 are provided on each connecting beam 220. In other embodiments, the number of first guide shafts 221 on each connecting beam 220 can also be one, three, four, etc., which can be set according to actual needs, and the present application does not make specific limitations.

[0070] Embodiment Two

[0071] This embodiment provides a lens dispensing fixture, which has a substantially same structure as that of Embodiment One, and is only improved on the basis of Embodiment One. Therefore, only the differences between the two are described herein, and the same structures of this embodiment and Embodiment One will not be elaborated herein.

[0072] Specifically, as Figure 7 and Figure 8 shown, in this embodiment, the pressing plate 200 further includes two oppositely arranged connecting beams 220. Two ends of the pressing portion 210 are respectively connected to the two connecting beams 220. The lens dispensing fixture further includes a limiting frame 300. The limiting frame 300 is fixed to the base 100. Guide holes are provided on opposite two sides of the limiting frame 300 along the length direction of the lens fixing portion 120. Second guide shafts 310 are arranged in one-to-one correspondence with the guide holes. The second guide shafts 310 are slidably inserted through the guide holes, and one end of each second guide shaft 310 is connected to the corresponding connecting beam 220. The second guide shafts 310 extend along the length direction of the lens fixing portion 120.

[0073] Through the cooperation of the second guide shaft 310 with the limit frame 300 and the connecting beam 220, the pressing part 210 has only the freedom degree along the length direction of the lens fixing part 120, which can prevent the pressing plate 200 from tilting during the movement, and further improves the smoothness of the movement of the pressing plate 200. Moreover, the second guide shaft 310 can also limit the height of the pressing plate 200 in the vertical direction, so that the pressing arm 211 can apply reliable pressure on the transmission nut 12 above the transmission nut 12.

[0074] Optionally, the position when one of the connecting beams 220 abuts against the limit frame 300 can be set as the termination position of the pressing plate 200. At this time, the pressing arm 211 abuts above the transmission nut 12. After such a setting, it is only necessary to push the pressing plate 200 to make the connecting beam 220 abut against the limit frame 300, which greatly reduces the installation difficulty of the pressing plate 200 and thus improves the installation efficiency of the pressing plate 200.

[0075] Optionally, multiple second guide shafts 310 can be correspondingly arranged for each connecting beam 220. In this embodiment, two second guide shafts 310 are correspondingly arranged for each connecting beam 220. In other embodiments, the number of second guide shafts 310 corresponding to each connecting beam 220 can also be three, four, etc., which can be set according to actual needs, and the present application does not make specific limitations.

[0076] Furthermore, at least part of the second guide shafts 310 are sleeved with elastic members 320. The second guide shafts 310 sleeved with elastic members 320 slide through the same side of the limit frame 300. The elastic members 320 are placed between the limit frame 300 and the end of the second guide shaft 310 not connected to the connecting beam 220. The elastic members 320 are configured to always have a tendency to push the second guide shaft 310 to pull the connecting beam 220 towards the limit frame 330 adjacent to the connecting beam 220. That is, by setting the elastic members 320, it can assist the staff to push the pressing plate 200 to move, greatly reducing the labor force.

[0077] For the convenience of understanding, the two connecting beams 220 are defined as the first beam and the second beam, and the sides of the limit frame 300 opposite to the first beam and the second beam are defined as the first side and the second side respectively. And when the first beam abuts against the first side, the pressing plate 200 is just installed in place. At this time, the pressing arm 211 abuts above the transmission nut 12. Then the elastic member 320 is sleeved on the second guide shaft 310 sliding through the first side.

[0078] It can be understood that the elastic member 320 can be selected but is not limited to a spring.

[0079] Furthermore, continue to refer to Figure 8, a boss 311 is provided at one end of the second guide shaft 310 that is not connected to the connecting beam 220, and the outer diameter of the boss 311 is greater than the diameter of the second guide shaft 310.
