Detailed implementation manners
[0023] To make the technical solutions and technical effects of the embodiments of the present application clearer, the embodiments of the present application will be described below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on this, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.
[0024] In the related art, an endoscope includes an illumination part and an imaging part, and generally an optical fiber is used for light conduction in the illumination part. Specifically, referring to Figure 3 , the optical fiber 240 penetrates into the connector 220 on the base 210 and reaches the head end seat through the inner cavity of the tube body 230, and the incident end of the optical fiber 240 located outside the connector 220 needs to be ground and trimmed. However, in the process of endoscope optical fiber processing, most of the optical fiber incident ends are directly ground manually, and it is difficult to grasp the grinding accuracy and the consistency of the grinding end face effect is poor.
[0025] The embodiments of the present application at least solve the above technical problems, and the embodiments of the present application will be elaborated in detail below with reference to the drawings.
[0026] Referring to Figure 1 and Figure 2, this application provides an optical fiber grinding auxiliary device 100, which includes a support member 110, a bracket 120, and a micrometer differential head 130. The support member 110 is provided with a feed outlet 111. The bracket 120 is connected to the support member 110, and a feed space is formed between the bracket 120 and the support member 110, and the feed space is aligned with the feed outlet 111. The optical fiber product 200 to be ground is movably accommodated in the feed space; the micrometer differential head 130 is installed on the bracket 120. The micrometer differential head 130 includes an operating end 131 and a feed end 132 that are drivingly connected. The feed end is connected to the optical fiber product to be ground, and the operating end 131 drives the feed end 132 to squeeze the optical fiber product 200 to be ground to drive the optical fiber product 200 to be ground to move toward the feed outlet 111.
[0027] In this application, the optical fiber grinding auxiliary device 100 precisely controls the size of the exposed part of the optical fiber product 200 to be ground by using the micrometer differential head 130, improves the grinding accuracy of the end face of the optical fiber 240, and enhances the consistency of the grinding effect; specifically, the bracket 120 can be a plate-like structure, the middle part of which protrudes away from the support member 110 and forms a cavity. The support member 110 is connected to the bracket 120 to form a feed space. The side of the support member 110 away from the bracket 120 can be connected to a grinding device, and then the micrometer differential head 130 is manipulated to press the optical fiber product 200 to be ground located in the feed space, so that it is exposed from the feed opening on the support member 110 for grinding. The operation is convenient, the feed accuracy is easy to control, the consistency of the grinding finished product is good, the production efficiency is high, and the operating end 131 is far from the grinding place, so the safety is strong.
[0028] Furthermore, the rotation amount of the operating end 131 of the micrometer differential head 130 is associated with the feed amount of the feed end 132, and the ratio of the rotation amount to the feed amount is large, that is, when the operating end 131 rotates multiple turns, the feed end 132 only advances a small distance, which is beneficial to precisely controlling the feed amount, avoiding excessive feed amount caused by operation errors, and reducing errors. In addition, precise scales are marked on the main body of the micrometer differential head 130, which is convenient for the operator to read the feed amount and is beneficial to controlling the feed accuracy.
[0029] It should be noted that this application can also control the feed speed of the feed end 132 by controlling the rotation speed of the operating end 131 of the micrometer differential head 130, so that the feed speed of the exposed part of the optical fiber product 200 to be ground is adapted to the grinding efficiency, and a better grinding effect is achieved.
[0030] In some embodiments, the micrometer differential head 130 includes a locking mechanism, and the locking mechanism locks the movement of the feed end 132. In this embodiment, after the operating end 131 of the micrometer differential head 130 controls the feed end 132 to feed in place, in order to avoid position rebound, it is necessary to use the locking mechanism to lock the position of the feed end 132, so that it is not necessary to continuously apply force to the operating end 131, saving labor.
[0031] Specifically, the bracket 120 is provided with a mounting hole 121, the micrometer differential head 130 is mounted on the mounting hole 121, and the feeding end 132 can pass through the mounting hole 121 to directly or indirectly press against the optical fiber product 200 to be ground.
[0032] In some embodiments, referring to Figure 1 and Figure 2 , the optical fiber grinding auxiliary device 100 further includes a movable seat 140, the movable seat 140 is movably arranged in the feeding space; the movable seat 140 has a limiting groove 141, and the optical fiber product 200 to be ground is mounted on the movable seat 140 through the limiting groove 141; when the micrometer differential head 130 presses and drives the optical fiber product 200 to be ground, the movable seat 140 moves synchronously with the optical fiber product 200 to be ground under the drive of the optical fiber product 200 to be ground. In some embodiments, the optical fiber grinding auxiliary device 100 further includes a guide post 150, the guide post 150 is connected to the support member 110, and the guide post 150 is distributed in the feeding space; the movable seat 140 is movably connected to the guide post 150. In some embodiments, the optical fiber grinding auxiliary device 100 further includes a return spring 160, the return spring 160 is sleeved on the guide post 150, and the return spring 160 is located between the support member 110 and the movable seat 140; when the movable seat 140 moves towards the feeding outlet 111, the return spring 160 has a resilience force to move the movable seat 140 away from the feeding outlet 111.
[0033] In the above embodiments, the optical fiber product 200 to be ground is mounted in the limiting groove 141 of the movable seat 140, avoiding the shaking of the optical fiber product 200 to be ground during the moving process, which may cause the grinding accuracy to decrease; in addition, the guide post 150 is erected between the support member 110 and the bracket 120 and passes through the avoidance hole 145 of the movable seat 140, so that the movable seat 140 moves linearly along the guide post 150, increasing the stability of the moving action; the return spring 160 abuts between the support member 110 and the movable seat 140, and the return spring 160 is compressed when the movable seat 140 moves towards the feeding outlet 111. After the grinding is completed, only by turning back the operating end 131 of the micrometer differential head 130, under the resilience force of the return spring 160, the movable seat 140 can be reset, and the operation is convenient.
[0034] Furthermore, when the feeding direction is the up-down direction, the return spring 160 can also provide damping and support during the feeding process, avoiding the movement of the movable seat 140 under its own gravity, which may affect the feeding accuracy.
[0035] Specifically, in some embodiments, the bracket 120 and the support member 110 are detachably connected by fasteners; alternatively, the bracket 120 and the support member 110 are snap-connected. In this embodiment, the bracket 120 is detachably connected to the fasteners, which is convenient for taking out or putting the optical fiber product 200 to be ground into or out of the limit groove 141 of the movable seat 140, and the operation is convenient.
[0036] In addition, in some embodiments, referring to Figure 2 , the movable seat 140 has a convex end 142, the convex end 142 faces the feed outlet 111, and the convex end 142 matches the feed outlet 111. In this embodiment, when the movable seat 140 moves towards the feed outlet 111, the convex end 142 of the movable seat 140 can pass through the feed outlet 111, and the feed outlet 111 limits the convex end 142, so that the structure is relatively stable during grinding; moreover, a positioning hole 144 is provided in the convex end 142, and the connector 220 of the optical fiber product 200 to be ground passes through the positioning hole 144, so as to further limit the optical fiber product 200 to be ground. During grinding, the incident end position of the optical fiber 240 at the connector 220 is more fixed, and the grinding effect is better.
[0037] In some embodiments, referring to Figure 1 and Figure 2 , a plurality of foot pads 180 are connected to the side surface of the support member 110 facing away from the bracket 120, and a protection space for the exposed part of the optical fiber product 200 to be ground is formed between the support surface formed by the plurality of foot pads 180 and this side surface of the support member 110.
[0038] Specifically, the foot pads 180 are distributed on the edge of the support member 110, avoiding the feed outlet 111, and the number is more than three. The size of the foot pads 180 is larger than the exposed size of the incident end of the optical fiber 240 after grinding. Therefore, when the optical fiber grinding auxiliary device 100 is directly placed after being separated from the grinding equipment, the incident end of the optical fiber 240 at the connector 220 will not be touched, playing a protective role.
[0039] In some embodiments, referring to Figure 1 and Figure 2 , the optical fiber grinding auxiliary device 100 further includes a cushion block 170, and the cushion block 170 is installed at the opening of the limit groove 141, and the cushion block 170 abuts against the part of the optical fiber product 200 to be ground located in the limit groove 141.
[0040] During the feeding process, the feeding end 132 of the micrometer differential head 130 directly presses against the cushion block 170, and the cushion block 170 presses against the supporting step 143 of the movable seat 140 and the base 210 of the optical fiber product 200 to be ground, so as to realize the indirect driving mode in which the micrometer differential head 130 squeezes the cushion block 170 and the cushion block squeezes the optical fiber product to be ground.
[0041] This embodiment avoids damaging the fiber optic product 200 to be ground by direct pressing, and can also prevent the feed end 132 of the micrometer differential head 130 from having an excessive feed distance, which affects the operation convenience. Additionally, by replacing the spacer 170 with different materials and sizes, it is possible to adapt to different specifications of the fiber optic product 200 to be ground, enhancing the versatility.
[0042] In addition, in some embodiments, the spacer 170 can be removed, and the feed end 132 of the micrometer differential head 130 can directly contact and press the fiber optic product to be ground, which can also achieve the purpose of precise feeding and is also within the protection scope of this application.
[0043] In some embodiments, the four corners of the spacer 170 have an expansion structure 171, and a supporting step 143 is formed at the opening of the limiting groove 141, and the supporting step 143 abuts against the expansion structure 171.
[0044] In the above embodiment, the spacer 170 is limited by the abutment of the expansion structure 171 at the corner with the supporting step 143 of the limiting groove 141. When the fiber optic grinding auxiliary device 100 is idle, under the resilience of the return spring 160, the spacer 170 is limited between the bracket 120 and the supporting step 143, with firm limitation and prevention of detachment.
[0045] Particularly, the above content only describes the structure related to the improvement of this application, and it does not mean that the fiber optic grinding auxiliary device 100 cannot include other components. Therefore, on the premise of not causing contradictions, the fiber optic grinding auxiliary device 100 can also have other components. For example, a clamping mechanism for the fiber optic product 200 to be ground, a monitoring system for the exposed amount of the fiber optic product 200 to be ground, etc. The embodiments of this application do not limit the composition of the fiber optic grinding auxiliary device 100.
[0046] In addition, it needs to be emphasized again that although the above content describes the embodiments of this application in combination with the drawings, those skilled in the art can still make various modifications and variations without departing from the concept of this application, and such modifications and variations will fall within the scope defined by the appended claims.
