Description

Technical Field

[0001] This utility model relates to the field of lens fixture technology, and in particular to a pin recycling fixture. Background Technology

[0002] Optical zoom lenses typically employ a drive screw and drive nut mechanism for movement, enabling the lens assembly to rotate. Specifically, the drive nut is secured using a pin with adhesive and a spring. Since the pin is small and its material is recyclable, it is suitable for recycling. However, current pin recycling methods mostly rely on manual labor, using tweezers to disassemble the pin. This method not only poses operational risks, potentially causing injury to operators, but is also technically demanding. Furthermore, the strength of the tweezers can limit their reuse, resulting in low recycling efficiency. Therefore, finding a simplified method for pin recycling, avoiding injury to workers, and effectively improving recycling efficiency is a problem that needs to be addressed by those in the field. Utility Model Content

[0003] The purpose of this utility model is to provide a pin recycling fixture, which can recycle pins in a simple way, avoid injury to workers, and effectively improve recycling efficiency.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A pin recycling fixture, comprising:

[0006] The system includes a base, a movable component, and a ejector pin. The movable component is movably disposed in the base along a first direction, and the ejector pin is disposed on the base. The lens is confined within the movable component and presses against the movable component to move toward the base along the first direction. During the movement of the lens, the ejector pin can push out a pin in the lens.

[0007] Optionally, the movable component includes a limiting member that is movable along the first direction. The limiting member has a positioning port on its side wall. The guide portion of the lens is correspondingly disposed with the positioning port. When the guide portion is located at the positioning port, the ejector pin and the pin are directly opposite each other.

[0008] Optionally, it also includes a guide post fixed to the base along the first direction, and the guide post is capable of passing through the guide portion.

[0009] Optionally, the limiting member is provided with a limiting hole through the first direction, the limiting hole is connected to the positioning port, and the lens can be embedded in the limiting hole.

[0010] Optionally, the movable component further includes a guide shaft and an elastic element. One end of the guide shaft is fixedly connected to the limiting member, and the other end is movably inserted into the base. The elastic element is sleeved on the outside of the guide shaft and located between the limiting member and the base.

[0011] Optionally, the guide shaft includes a connecting shaft body, and the two ends of the connecting shaft body are respectively provided with a connecting end and a limiting end. The connecting end is connected to the limiting member, and the limiting end is movably disposed in the inner cavity of the base.

[0012] Optionally, the base is provided with a movable hole, the connecting shaft passes through the movable hole, and the outer diameter of the limiting end is larger than the inner diameter of the movable hole.

[0013] Alternatively, the ejector pin may be provided with an ejector head for ejecting the pin.

[0036] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and specific implementation methods.

[0037] like Figures 1-9 As shown, this embodiment provides a pin recovery fixture, including a base 10, a movable component 20, a guide post 30, and a push pin 40, for recovering pins 200 from a lens 100. Specifically, the axial direction of the base 10 is set as a first direction, the movable component 20 is movably disposed in the base 10 along the first direction, and the guide post 30 and the push pin 40 are both fixed to the base 10 along the first direction. Optionally, the lens 100 can be confined within the movable component 20 and can press the movable component 20 to move towards the base 10 along the first direction. During the movement of the lens 100, the push pin 40 can push out the pin 200 from the lens 100 for easy recovery. This replaces the manual method of using tweezers or other tools to recover the pin 200, avoids injury to operators, and effectively improves recovery efficiency.

[0038] like Figure 3 and Figure 4As shown, specifically, the lens 100 is provided with a top 110, a limiting part 120, and a bottom 130 from top to bottom, wherein the outer diameter of the limiting part 120 is larger than the outer diameters of the top 110 and the bottom 130. Further, a guide part 140 and a support base 150 protrude from one side of the lens 100, wherein the guide part 140 has a guide hole 141 extending along a first direction, and the guide part 140 is configured as a cavity structure. Further, a pin 200 is disposed in the mounting base 150, and a spring is sleeved on the outside of the pin 200. The rotating end of the transmission nut is movably disposed on the support base 150 and the outside of the pin 200 by the spring, thereby ensuring the fixation of the transmission nut. When the lens 100 presses against the movable component 20 and moves towards the base 10 along the first direction, the ejector pin 40 can push the pin 200 out of the mounting base 150, so that the top end of the pin 200 protrudes from the upper surface of the mounting base 150, facilitating the removal and recycling of the pin 200 by the operator.

[0039] like Figure 1 and Figure 2 As shown, in this embodiment, the base 10 is provided with an inner cavity 101 to facilitate the movement of the movable component 20 within the base 10 along a first direction. Combined with... Figures 5-9 As shown, specifically, in this embodiment, the movable component 20 includes a limiting member 21, a guide shaft 22, and an elastic member 23. Optionally, two guide shafts 22 and two elastic members 23 are provided. One end of the guide shaft 22 is fixedly connected to the limiting member 21, and the other end is movably inserted into the base 10. The elastic member 23 is sleeved on the outside of the guide shaft 22 and located between the limiting member 21 and the base 10. Optionally, the limiting member 21 is movable along a first direction, and the two guide shafts 22 are spaced apart along the first direction. An elastic member 23 is provided on the outside of each guide shaft 22. In this embodiment, the elastic member 23 is set as a spring. In other embodiments, it can also be set as needed. Thus, the movement of the limiting member 21 in the first direction can be realized through the guide shaft 22 and the elastic member 23.

[0040] Specifically, the limiting member 21 is configured as an annular structure with a notch, and a limiting hole 201 is provided through the center of the limiting member 21 along the first direction. The lens 100 can be embedded in the limiting hole 201 to ensure the stable placement of the lens 100 on the limiting member 21. For example, the bottom 130 is embedded in the limiting hole 201, and the outer diameter of the limiting part 120 is larger than the inner diameter of the limiting hole 201. Thus, the lower surface of the limiting part 120 can abut against the upper top surface of the limiting member 21 to ensure the stable placement of the lens 100 on the limiting member 21.

[0041] Furthermore, a positioning opening 202 is provided on the side wall of the limiting member 21, so that the limiting member 21 forms an annular structure with a notch, and the positioning opening 202 is connected to the limiting hole 201. Specifically, the positioning opening 202 is correspondingly arranged with the guide part 140 and the mounting base 150, so as to avoid the protruding guide part 140 and mounting base 150 of the lens 100, while accurately positioning the placement position of the lens 100 on the limiting member 21. For example, when the guide part 140 is located at the positioning opening 202, the ejector pin 40 and the pin 200 are arranged facing each other, so as to position the placement position of the lens 100 through the positioning opening 202, realize the precise alignment of the pin 200 and the ejector pin 40, ensure the subsequent accurate ejection of the pin 200, and improve the recycling efficiency.

[0042] like Figure 7 As shown, in this embodiment, the guide shaft 22 includes a connecting shaft 222, and both ends of the connecting shaft 222 are respectively provided with a connecting end 221 and a limiting end 223. Specifically, the connecting end 221 is connected to the limiting member 21, the limiting end 223 is movably inserted through the base 10 and located in the inner cavity 101, and the elastic member 23 is sleeved on the outside of the connecting shaft 222. Optionally, the base 10 is provided with a movable hole communicating with the inner cavity 101, the connecting shaft 222 is inserted through the movable hole, and can move up and down in the first direction within the movable hole. Further, the outer diameter of the limiting end 223 is larger than the inner diameter of the movable hole, thereby preventing the guide shaft 22 from detaching from the base 10. Exemplarily, the connecting end 221 and the limiting member 21 are screwed together to ensure a stable connection between the two. Other connection methods can also be used in other embodiments, which are not limited here.

[0043] like Figure 8 As shown, in this embodiment, the guide post 30 is fixed on the base 10 along the first direction, and the guide post 30 can pass through the guide hole 141 of the guide part 140 and extend into the cavity of the guide part 140 to ensure that the lens 100 can only move axially in the first direction and will not rotate. While achieving guidance, it further ensures the precise correspondence between the ejector pin 40 and the pin 200.

[0044] like Figure 9 As shown, the ejector pin 40 includes a support portion 41 and a fixing portion 42 connected to each other, and an ejector pin head 401 is provided at the end of the support portion 41 opposite to the fixing portion 42. Exemplarily, the support portion 41 and the fixing portion 42 can be configured as an integrally formed structure to improve mechanical strength. Optionally, the ejector pin head 401 is used to eject the pin 200, so that the tip of the pin 200 can protrude from the upper surface of the support base 150, facilitating timely retrieval of the pin 200 by the operator. Exemplarily, the outer diameter of the ejector pin head 401 is smaller than the outer diameter of the pin 200, so that when the lens 100 moves downward in the first direction, the ejector pin head 401 can eject the pin 200 out of the lens 100.

[0045] Furthermore, the fixing part 42 is connected to the base 10, and the supporting part 41 extends out of the base 10 to ensure that the ejector pin 401 can contact the pin 200. For example, in this embodiment, the base 10 is provided with a threaded hole, and the fixing part 42 is screwed into the threaded hole to achieve stable installation of the ejector pin 40 on the base 10.

[0046] Working process: The protruding guide portion 140 and mounting base 150 of the lens 100 are placed corresponding to the positioning port 202 of the limiting member 21, so that the bottom 130 is embedded in the limiting hole 201 of the limiting member 21, and the limiting part 120 can be seated on the upper surface of the limiting member 21. At the same time, the guide post 30 can pass through the guide hole 141 and extend into the guide portion 140. Then, the lens 100 is pushed downward along the first direction, so that the limiting member 21 and the guide shaft 22 move synchronously towards the base 10 along the first direction and squeeze. The elastic element 23 continues until the pin head 401 of the ejector pin 40 contacts the pin 200, causing the top of the pin 200 to protrude from the upper surface of the support base 150. The operator promptly retracts the pin 200 and then stops applying force to the lens 100. Under the action of the elastic element 23, the limiting element 21 drives the guide shaft 22 to return to its initial position, so as to retract the pin 200 of the next lens 100, realizing assembly line operation, avoiding manual operation with tweezers, and effectively improving the recycling efficiency.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
