Description

Technical Field

[0001] The utility model relates to the technical field related to medical equipment, and in particular to a lens assembly tooling device. Background Art

[0002] At present, medical endoscopes have become an indispensable inspection equipment in modern medicine and are widely used in clinical diagnosis and treatment. The components of medical endoscopes include lighting systems and image transmission lenses. The assembly accuracy of the image transmission lens of the endoscope is of great significance to the imaging quality and stability of the endoscope.

[0003] At present, when assembling the micro lens of an endoscope, the lens can be assembled by using an adjustable slender pen tip to appropriately squeeze the objective lens on the base, or the lens can be assembled into the lens barrel using tweezers through a simple fixing fixture. However, in the existing lens assembly method, it is difficult for the force-applying tool (such as the above-mentioned slender pen tip, tweezers, etc.) to remain coaxial with the lens, resulting in an unstable force-applying angle. The assembly process of the micro lens in the lens barrel is prone to cause the main light angle of the lens group to deviate, making it difficult to ensure the coaxiality of the lens. In addition, during the above-mentioned assembly process, the force-applying tool is also prone to uneven force application, which can cause scratches and damage to the lens, thereby affecting the imaging clarity of the endoscope.

[0053] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0054] Combine the following Figures 1 to 10 , describing an embodiment of the lens assembly tooling device of the utility model.

[0055] According to an embodiment of the utility model, on the one hand, a lens assembly tooling device is provided, including a frame 1, at least one fixed seat 2, at least one group of assembly components and a coaxiality adjustment mechanism, wherein the fixed seat 2 is arranged at the lower part of the frame 1, the lens 3 is arranged on the fixed seat 2, the assembly component is arranged at the upper part of the frame 1, at least one group of assembly components corresponds to the position of at least one fixed seat 2, the assembly component is used to assemble the lens 3, the coaxiality adjustment mechanism is movably arranged on the frame 1, and the coaxiality adjustment mechanism is used to adjust the coaxiality between the lens 3 arranged on the fixed seat 2 and the assembly component.

[0056] This lens assembly tooling device can adjust the coaxiality between the lens 3 arranged on the fixed seat 2 and the assembly component by setting a coaxiality adjustment mechanism. Before assembling the lens 3, the coaxiality between the lens 3 and the assembly component is adjusted first to keep the lens 3 and the assembly component coaxial, and then the lens 3 is assembled using the assembly component. The force angle of the assembly component on the lens 3 remains unchanged, which can make the main light angle of the lens group after assembly consistent and the coaxiality good, thereby ensuring the detection accuracy and imaging quality of subsequent detection equipment.

[0057] like Figure 1-2 As shown, the frame 1 of the lens assembly tooling device of this embodiment is the bearing structure of the whole device. The frame 1 has a certain structural strength. The frame 1 includes a frame 104 and a base 105. The base 105 is used to be firmly placed on a flat surface such as a desktop or an operating table. The lower legs of the frame 104 are connected to the base 105. The upper part of the frame 104 is a box structure (a rectangular parallelepiped structure) with a cavity inside. The box structure has a first assembly plate 101 and a second assembly plate 102 from top to bottom, and the first assembly plate 101 and the second assembly plate 102 are preferably arranged horizontally, and the above-mentioned cavity is provided between the first assembly plate 101 and the second assembly plate 102. The first assembly plate 101, the second assembly plate 102, the frame 104 and the base 105 can be connected by fasteners such as screws.

[0058] The fixing seat 2 is arranged at the lower part of the frame 1. Specifically, the fixing seat 2 is arranged on the upper surface of the base 105. One, two, three or other fixing seats 2 can be arranged on the base 105 as needed. In this embodiment, two fixing seats 2 are arranged on the base 105, and two lenses 3 can be assembled. The fixing seat 2 is a columnar structure as a whole. The bottom of the fixing seat 2 is connected to the base 105, and the top of the fixing seat 2 is used to place the lens 3 for lens assembly. In this embodiment, the fixing seat 2 is a cylindrical structure.

[0059] The top of the fixing seat 2 has a slot into which the lens 3 can be inserted to limit the position of the lens 3. The depth of the slot allows the lower structure of the lens 3 to be inserted, and the upper structure of the lens 3 is exposed from the top plane of the fixing seat 2 for subsequent lens assembly operations.

[0060] The lens 3 is composed of a plurality of lenses, and its specific structure is not described here in detail.

[0061] The assembly components are arranged on the upper part of the frame 1, specifically, the assembly components are arranged on the frame 104, at least one group of assembly components corresponds to at least one fixing seat 2, that is, one group of assembly components corresponds to one fixing seat 2 one by one, and one group, two groups, three groups, etc. of assembly components can be arranged as needed. In this embodiment, two groups of assembly components are arranged, each corresponding to one fixing seat 2, and the assembly components are used to assemble the lens 3.

[0062] Further, the assembly component has an assembly position close to and assembled with the lens 3 and a suspension position away from the lens 3, and the assembly component is movably arranged between the assembly position and the suspension position.

[0063] The assembly component has an assembly position and a suspension position, and the assembly component can move between the assembly position and the suspension position. With the movement of the assembly component, the assembly component can move from the assembly position to the suspension position, and can also move from the suspension position to the assembly position. Moreover, the force angle of the assembly component on the lens is always coaxial with the lens, thereby ensuring the coaxiality of the lens after assembly. When the assembly component is located at the assembly position, the lens assembly operation can be performed under manual operation. When the lens assembly is not required, the assembly component can be located at the suspension position for subsequent use.

[0064] Furthermore, the assembly component is vertically penetrated in the first assembly plate 101 and the second assembly plate 102 to realize the assembly of the lens. The assembly component includes a support rod 4, a fixing ring 6 and an elastic member 7. The support rod 4 is vertically penetrated in the first assembly plate 101 and the second assembly plate 102. The fixing ring 6 is sleeved on the outer wall of the support rod 4. The fixing ring 6 moves between the first assembly plate 101 and the second assembly plate 102 with the support rod 4. The elastic member 7 is sleeved on the outside of the support rod 4. The upper end of the elastic member 7 is fixed to the first assembly plate 101, and the lower end is connected to the fixing ring 6. When the assembly component is in a suspended position, the elastic member 7 is in a compressed state.

[0065] The assembly component is vertically disposed on the first assembly plate 101 and the second assembly plate 102 , that is, the assembly component can move in a direction perpendicular to the first assembly plate 101 and the second assembly plate 102 .

[0066] like Figure 3-4 As shown, specifically, the assembly assembly includes a support rod 4, a fixing ring 6 and an elastic member 7. The support rod 4 is vertically arranged in the first assembly plate 101 and the second assembly plate 102, the upper end of the support rod 4 is placed on the first assembly plate 101, and the lower end of the support rod 4 is placed under the second assembly plate 102, correspondingly, the upper and lower ends of the support rod 4 are exposed from the frame 104, the first assembly plate 101 is formed with a first assembly hole, the second assembly plate 102 is formed with a second assembly hole, and the support rod 4 is arranged through the first assembly hole and the second assembly hole.

[0067] The fixing ring 6 is sleeved on the outer wall of the support rod 4, and the fixing ring 6 is fixed to the outer wall of the support rod 4. The fixing ring 6 can move up and down in the vertical direction together with the support rod 4, and the outer diameter of the fixing ring 6 is larger than the inner diameter of the first assembly hole and the second assembly hole, so that the fixing ring 6 cannot fall out of the second assembly plate 102 downwards, nor can it fall out of the first assembly plate 101 upwards, so as to limit the assembly component and ensure the reliability of the structure. The fixing ring 6 moves with the support rod 4 between the first assembly plate 101 and the second assembly plate 102 to realize the movement of the assembly component between the assembly position and the suspension position.

[0068] The elastic member 7 is specifically a spring. The elastic member 7 is sleeved on the outside of the support rod 4, the upper end of the elastic member 7 is fixed to the first assembly plate, and the lower end is connected to the fixing ring 6. When the assembly component is in the suspended position, the elastic member 7 is in a compressed state. When the assembly component is in the suspended position, the spring in the compressed state can accumulate a certain restoring force. When the assembly component is out of the suspended position (after being unlocked from the suspended position), under the action of the spring restoring force, the assembly component can apply a uniform pressure to the lens 3 to assist in assembling the lens.

[0069] Furthermore, the assembly component also includes a sleeve 5 , which is disposed in the first assembly hole of the first assembly plate 101 , the support rod 4 is passed through the sleeve 5 , and the upper end of the elastic member 7 is fixed to the sleeve 5 .

[0070] The height of the sleeve 5 matches the thickness of the first assembly plate 101 , the outer wall of the sleeve 5 is fixed to the inner wall of the first assembly hole, the support rod 4 passes through the sleeve 5 , and the upper end of the elastic member 7 is fixed to the sleeve 5 to achieve fixation with the first assembly plate 101 .

[0071] Furthermore, the assembly component also includes a tablet pressing pen 8, which is arranged at one end of the support rod 4 facing the lens 3.

[0072] The upper end of the tablet pressing pen 8 is connected to the end of the support rod 4 facing the lens 3, and the lower end of the tablet pressing pen 8 is a pen-shaped structure for contacting the lens 3. In this embodiment, the upper part of the tablet pressing pen 8 has a concave groove structure, and the end of the support rod 4 is suitable for inserting into the groove structure, and then the tablet pressing pen 8 is connected and fixed to the support rod 4 by a radially screwed bolt.

[0073] Furthermore, the surface where the tablet pressing pen 8 contacts the lens 3 is a plane; or the surface where the tablet pressing pen 8 contacts the lens 3 is provided with a groove 801, and the edge of the groove 801 contacts the lens 3.

[0074] The surface of the tablet pressing pen 8 in contact with the lens 3 has two structural forms. The first is that the surface of the tablet pressing pen 8 in contact with the lens 3 is a plane, such as Figure 5-7 As shown, this type of tablet pressing pen 8 is suitable for assembling plane mirrors and concave lenses. Through large-area plane contact, the lens is subjected to uniform force, reducing the possibility of scratches and damage to the lens, and ensuring imaging clarity; the second type is that the contact surface between the tablet pressing pen 8 and the lens 3 has an inwardly concave groove 801. In some embodiments, the groove 801 is set at the center of the contact surface, and the groove 801 is a circular groove, that is, the cross-sectional shape of the groove 801 perpendicular to the axial direction of the tablet pressing pen 8 is circular. Figure 8-10 As shown, the edge of the groove 801 contacts the lens. This tablet pressing pen 8 is suitable for assembling convex lenses and concave lenses. Especially when assembling a convex lens, the edge of the groove 801 uniformly applies pressure to the convex lens. The contact area is large, which avoids the problem of assembly deviation caused by point contact between the flat tablet pressing pen and the convex lens. Moreover, the large-area contact can better protect the lens surface, reduce problems such as scratches on the lens surface, and ensure assembly quality and subsequent imaging clarity. The above two structural forms of tablet pressing pens 8 can be selected and used according to the lenses of different lenses.

[0075] In order to facilitate the subsequent coaxiality adjustment of the lens and the assembly component, the various components in the assembly component must also remain coaxial. The coaxiality adjustment process of the various components of the assembly component can adopt the existing coaxiality adjustment method, which is not described in detail here.

[0076] Furthermore, the lens assembly tooling device of this embodiment further includes a locking mechanism, which is used to lock the assembly component so that it is located in the suspended position, or to unlock the assembly component from the suspended position.

[0077] When the assembly component is in the suspended position, it needs to be locked in the suspended position by a locking mechanism. When the lens needs to be assembled, the locking mechanism can unlock the assembly component so that the assembly component can move from the suspended position to the assembly position.

[0078] like Figure 1 As shown, the locking mechanism includes a locking handle 9 and a slide groove 10. The slide groove 10 is formed on the upper part of the frame 1. The slide groove 10 includes a vertical groove portion 1001 and a locking groove portion 1002 that are interconnected. One end of the locking handle 9 is connected to the support rod 4, and the other end passes through the slide groove 10 and can move along the slide groove 10. When the locking handle 9 moves to the locking groove portion 1002, the assembly component is in a suspended position.

[0079] Specifically, a slide groove 10 is formed on the side wall of the frame 104. The slide groove 10 is a hollow groove. The slide groove 10 includes a vertical groove portion 1001 and a locking groove portion 1002. The length direction of the vertical groove portion 1001 is arranged along the vertical direction. The locking groove portion 1002 is connected to the vertical groove portion 1001. In this embodiment, the locking groove portion 1002 is arranged horizontally, that is, the slide groove 10 as a whole is a T-slot structure rotated 90°.

[0080] One end of the locking handle 9 is connected to the fixing ring 6 to achieve the connection between the locking handle 9 and the support rod 4. The other end of the locking handle 9 passes through the slide groove 10 and can move along the slide groove 10. By operating the locking handle 9, the fixing ring 6 and the support rod 4 can be driven to move along the slide groove 10. When the locking handle 9 is placed in the vertical groove portion 1001, the support rod 4 can move in the vertical direction to assemble the lens, and when the locking handle 9 is placed in the locking groove portion 1002, the assembly component is in a suspended position, and the lens assembly is not performed at this time.

[0081] Optionally, the locking handle 9 is connected to the fixing ring 6 along the radial direction of the fixing ring 6, and the fixing ring 6 is coaxial with the support rod 4. When the locking handle 9 enters the locking groove 1002, the locking handle 9 drives the fixing ring 6 to rotate a certain angle, so that the locking handle 9 is stuck in the locking groove 1002, and the assembly component can be locked in the suspended position.

[0082] In this embodiment, the assembly component cannot move horizontally in the frame 104. By setting the coaxiality adjustment mechanism at the lower part of the frame 1 (i.e., on the base 105), the horizontal position of the fixing seat 2 and the lens 3 thereon can be adjusted, thereby adjusting the coaxiality between the lens 3 and the assembly component.

[0083] Of course, in other embodiments, the coaxiality adjustment mechanism can also be set on the upper part of the frame 1 (i.e., on the frame 104) to adjust the horizontal position of the assembly component, so that the fixed seat 2 and the lens 3 thereon cannot move in the horizontal direction, thereby adjusting the coaxiality between the lens 3 and the assembly component. Alternatively, the coaxiality adjustment mechanism is simultaneously set on the upper part (i.e., on the frame 104) and the lower part (i.e., on the base 105) of the frame 1, so that the horizontal position of the assembly component can be adjusted, and the horizontal position of the fixed seat 2 and the lens 3 thereon can also be adjusted, thereby adjusting the coaxiality between the lens 3 and the assembly component. The setting method of the above coaxiality adjustment mechanism can be selected according to needs.

[0084] Furthermore, in this embodiment, the coaxiality adjustment mechanism includes an adjusting seat 11, the adjusting seat 11 is arranged at the lower part of the frame 1, the fixed seat 2 is arranged on the adjusting seat 11, the adjusting seat 11 has an adjusting hole 1101, the lower part of the frame 1 has a mounting hole 103, the inner diameter of the adjusting hole 1101 is larger than the inner diameter of the mounting hole 103, and the fastener 12 passes through the adjusting hole 1101 and the mounting hole 103 in sequence to fix the adjusting seat 11 to the lower part of the frame 1.

[0085] The adjustment seat 11 is a flat plate structure. The adjustment seat 11 is arranged on the upper surface of the base 105. The adjustment seat 11 can move horizontally relative to the base 105 to adjust the coaxiality between the lens 3 on the fixed seat 2 and the assembly component. Figure 4 As shown, the x and y directions are horizontal directions, the z direction is the vertical direction, and the two arc-shaped arrows indicate that the adjustment seat 11 can be rotated horizontally to adjust its position. Specifically, the adjustment seat 11 is formed with an adjustment hole 1101, and the number of the adjustment holes 1101 can be selected and set as needed. In this embodiment, two adjustment holes 1101 are provided, and the fixed seat 2 is arranged between the two adjustment holes 1101. Two or more mounting holes 103 are formed on the upper surface of the base 105 to correspond to one, two or more fixed seats 2. In this embodiment, four mounting holes 103 are formed on the upper surface of the base 105. Since the inner diameter of the adjustment hole 1101 is larger than the inner diameter of the mounting hole 103, the horizontal position of the adjustment seat 11 can be moved, thereby realizing the coaxiality adjustment. The fastener 12 is usually a bolt. After the coaxiality of the lens 3 and the assembly component is adjusted (within the allowable tolerance range), the position of the adjustment seat 11 is fixed by passing the fastener 12 through the adjustment hole 1101 and the mounting hole 103.

[0086] The center position of the adjustment seat 11 has a fixing seat assembly groove for setting the fixing seat 2. The fixing seat 2 can be firmly set in the fixing seat assembly groove. When the horizontal position of the adjustment seat 11 is adjusted, the fixing seat 2 and the lens 3 thereon move and adjust synchronously with the adjustment seat 11.

[0087] The following describes the process of assembling the lens by the lens assembly tooling device of this embodiment:

[0088] First, it is necessary to adjust the coaxiality of the assembly, that is, to ensure that the support rod 4, the sleeve 5, the fixing ring 6 and the tablet pressing pen 8 are coaxial. The coaxiality adjustment process can adopt the existing adjustment method, which will not be repeated here;

[0089] Then, place the lens barrel of the lens 3 on the fixing seat 2, and then place the fixing seat 2 on the adjusting seat 11, and ensure that the lens barrel of the lens 3, the fixing seat 2 and the adjusting seat 11 are coaxial;

[0090] The adjusting seat 11 is moved horizontally to adjust the coaxiality between the lens 3 and the assembly component, so that the coaxiality between the lens 3 and the assembly component is within the allowable tolerance range, and then the adjusting seat 11 is fixed with the fastener 12. At this time, the coaxiality between the lens 3 and the assembly component is adjusted;

[0091] Afterwards, if the lens 3 does not need to be assembled temporarily, or other preparations need to be made, the locking handle 9 can be controlled to drive the support rod 4 to move along the slide groove 10, and the locking handle 9 can be inserted into the locking groove 1002 to place the assembly component in a suspended position;

[0092] When the lens needs to be assembled, the locking handle 9 is controlled to drive the support rod 4 to leave the locking groove 1002 and enter the vertical groove 1001. At this time, the assembly component is unlocked. Under the action of the restoring force of the elastic member 7 and manual operation, the pressing pen 8 applies appropriate pressure to the lens of the lens 3 to assemble the lens into the lens barrel. Then, the locking handle 9 is controlled to drive the support rod 4 to move upward to the locking groove 1002, and the fixing seat 2 is taken out from the adjusting seat 11, and then the assembled lens 3 is taken out, thereby completing the assembly of a lens.

[0093] In the above lens assembly process, the assembly component and the lens remain coaxial, and the assembly component always applies a downward force to the lens, which can ensure that the force is applied evenly and ensure that the coaxiality of the lens after assembly meets the requirements. In addition, different pressing pens 8 can be selected according to different lenses, such as convex lenses, concave lenses, and plane mirrors, to further improve the uniformity of the force, ensure that the lens will not be damaged during assembly, and will not affect the surface flatness of the lens, so that the assembly process is more stable and reliable, and will not affect the imaging quality of the lens.

[0094] The lens assembly tooling device of this embodiment has a simplified design, high lens assembly efficiency, and good stability and consistency, which is conducive to the application of lenses in medical equipment such as endoscopes, and the high stability and imaging reliability of fixed imaging and lighting lenses. Through adjustable coaxiality and a structure that adapts to different lens shapes, the purpose of stable and reliable installation of the lens is further guaranteed and practicality is improved.

[0095] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
