Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical module processing technology, and in particular to a swivel plate for endoscopic detection of optical devices. Background Technology
[0002] The optical module includes a housing, a circuit board inside the housing, and optical components connected to the circuit board. Each optical component includes a cylindrical housing base containing optical elements. A raised ring is formed on the outer periphery of the housing, and a connecting wire is located at the rear end of the housing and soldered to the circuit board. During the production of the optical module, the cleanliness of the optical components requires multiple endoscopic inspections to ensure the quality of the optical module. During inspection, operators insert each optical component onto the endoscope lens of an optical component inspection machine, and then check the cleanliness of the lens through imaging results. This inspection method requires operators to approach the endoscope lens one by one, which can easily lead to missed inspections. Furthermore, insufficient grip strength during inspection can cause optical components to fall, potentially damaging them. Utility Model Content
[0003] This invention provides a swivel plate for endoscopic detection of optical devices, which overcomes the shortcomings of the prior art, solves the problem of easy missed detection, and also prevents optical devices from falling off, thus having strong practicality.
[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:
[0005] A swivel plate for endoscopic inspection of optical devices is mounted on an endoscopic inspection machine for optical devices. An endoscope lens is located at the front end of the machine, and a hanging shaft is rotatably mounted at the front end. An insert shaft is formed at the outer end of the hanging shaft, the outer diameter of which is larger than that of the insert shaft. The machine includes a collar, and a ring member is formed at the outer end of the collar. A U-shaped opening is formed on the outer periphery of the ring member. A U-shaped groove is formed on the inner wall of the U-shaped opening, the width of which is larger than the width of the U-shaped opening. An inner pressure arc plate passes through the U-shaped groove, and a pressure plate is formed at the outer end of the inner pressure arc plate. A guide screw passes through the inner end of the pressure plate, and the inner end of the guide screw is connected via a thread. An internal pressure spring is fitted onto the guide screw attached to the ring. The inner end of the internal pressure spring abuts against the outer wall of the pressure plate, and the outer end of the internal pressure spring abuts against the inner end of the guide screw nut. In application, the housing of the optical device is located within the U-shaped opening, and the convex ring is located within the U-shaped groove. The inner end of the internal pressure plate acts on the other side of the convex ring under the elastic force of the internal pressure spring. This structural design facilitates the placement of the optical devices. During testing, the ring is rotated so that each optical device is directly facing the endoscope lens. Then, each optical device facing the endoscope lens is pushed inward to bring the endoscope lens closer to the optical element of the optical device for testing. The advantage of this method is that during operation, the operator does not need to hold the optical device but can perform testing by pressing it. Furthermore, since the optical device is fixed to the ring, the probability of missed detection is reduced.
[0006] Furthermore, since the insertion shaft has rotational flexibility and a high degree of overlap between its own axis and the rotation axis during rotation, the accuracy during detection is improved. Therefore, multiple insertion strips are formed on the outer periphery of the insertion shaft, and multiple slots are opened on the inner periphery of the collar. The number of insertion strips is the same as the number of slots, and the insertion strips are inserted into the slots, so that the ring can rotate with the insertion shaft.
[0007] Furthermore, an inner ring is coaxially fixed to the other end face of the ring component by a first screw. A constraint ring is formed on the outer end of the inner ring. A rotating ring is sleeved on the inner ring and is located between the ring component and the constraint ring. Multiple external convex plates are formed on the outer periphery of the rotating ring. An arc-shaped groove is formed on one side of the external convex plate. The tail section of the optical device's housing is inserted into the arc-shaped groove to fix the optical device and prevent it from falling off due to insufficient internal pressure of the inner pressure arc plate during detection rotation.
[0008] Furthermore, slots are symmetrically provided on the outer periphery of the constraint ring, and two pairs of limiting screws are threadedly connected to the rotating ring. An inner moving plate is movable on each pair of limiting screws. A pair of guide elongated holes are provided on the inner moving plate, and the limiting screws pass through the guide elongated holes. A limiting insert plate is formed on the inner wall of the inner moving plate. The limiting insert plate is inserted into the slot to lock the rotation angle of the rotating ring, thereby ensuring the stability of the arc groove in limiting the housing.
[0009] Furthermore, a second screw is threaded onto the constraint ring, a pressure ring is fitted onto the second screw, and an inner top spring is fitted onto the second screw. The inner end of the inner top spring abuts against the pressure ring, and the outer end of the inner top spring abuts against the inner end of the second screw nut. A limit rod is welded onto the limit plate, and the limit rod passes through the pressure ring to limit the inner moving plate, so as to prevent the movement of the inner moving plate during rotation from adversely affecting the limiting effect.
[0010] The advantages of the above technical solution are:
[0011] This invention provides a stable and limited position for the optical device housing to prevent the optical device from falling during testing. Furthermore, the testing can be completed simply by pressing the optical device, thus reducing the risk of missed detections. Attached Figure Description

[0017] Figure 5 A magnified view of point A is shown. Detailed Implementation
[0018] like Figures 1-5As shown, a swivel plate for endoscopic inspection of optical devices is mounted on an endoscopic inspection machine 1. An endoscope lens 10 is located at the front end of the endoscopic inspection machine 1. A hanging shaft 11 is rotatably mounted at the front end of the endoscopic inspection machine 1. An insert shaft 12 is formed at the outer end of the hanging shaft 11. The outer diameter of the hanging shaft 11 is larger than the outer diameter of the insert shaft 12. The swivel plate includes a collar 2. A ring member 21 is formed at the outer end of the collar 2. A U-shaped opening 22 is formed on the outer periphery of the ring member 21. A U-shaped groove 23 is formed on the inner wall of the U-shaped opening 22. The width of the groove 23 is greater than the width of the U-shaped opening 22. An inner pressure arc plate 27 is inserted into the U-shaped groove 23. A pressure plate 26 is formed on the outer end of the inner pressure arc plate 27. A guide screw 24 is inserted on the inner end of the pressure plate 26. The inner end of the guide screw 24 is threaded to the ring 21. An inner pressure spring 25 is sleeved on the guide screw 24. The inner end of the inner pressure spring 25 abuts against the outer wall of the pressure plate 26, and the outer end of the inner pressure spring 25 abuts against the inner end of the nut of the guide screw 24.
[0019] In this embodiment, the operator places the housing into each U-shaped opening 22 one by one. When placing, the convex ring needs to be placed in the U-shaped groove 23. When placing, the inner pressure arc plate 27 needs to be pulled outward first. After placing, the outward pulling force is released. At this time, the inner pressure arc plate 27 will be pressed against the convex ring under the elastic force of the inner pressure spring 25, thus achieving the purpose of fixing the optical device. Then, the collar 2 is placed on the insert shaft 12, and the inner end of the collar 2 abuts against the outer end of the hanging shaft 11. Then, the ring 21 is rotated so that each optical device passes through the endoscope lens 10. When the optical device is facing the endoscope lens 10, the operator presses the optical device inward to bring it closer to the endoscope lens 10 and observes the condition of the optical element through the endoscope lens 10. The substandard devices are marked until the detection operation of the optical device on the plate is completed. After the detection, the inner pressure arc plate 27 will be pressed against the convex ring under the elastic force of the inner pressure spring 25, and then the plate and the optical device on it will be rotated.
[0020] In some embodiments, multiple inserts are formed on the outer periphery of the insert shaft 12, and multiple slots 20 are provided on the inner periphery of the collar 2. The number of inserts and slots 20 is the same, and the inserts are inserted into the slots 20. This ensures that the ring 21 does not rotate relative to the insert shaft 12, but rotates with the insert shaft 12, thus solving the problem of gaps between the insert shaft 12 and the collar 2 affecting accuracy.
[0021] In some embodiments, an inner ring 3 is coaxially mounted on the other end face of the ring member 21 and fixed by a first screw 31. A constraint ring 30 is formed on the outer end of the inner ring 3. A rotating ring 32 is sleeved on the inner ring 3, located between the ring member 21 and the constraint ring 30. A plurality of external protrusions 33 are formed on the outer periphery of the rotating ring 32, and an arc-shaped groove 34 is formed with an opening on one side of the external protrusions 33. Slots are symmetrically provided on the outer periphery of the constraint ring 30. Two pairs of limiting screws 35 are threadedly connected to the rotating ring 32. An inner moving plate 36 is movably provided on each pair of limiting screws 35. A pair of guide elongated holes 37 are provided on the inner moving plate 36, and the limiting screws 35 pass through the guide elongated holes 37. A limiting insert plate 38 is formed on the inner wall of the inner moving plate 36, and the limiting insert plate 38 is inserted into the slot. When positioning the optical device, the operator rotates the rotating ring 32. During the rotation, the optical device will pass through the arc-shaped groove 34, and then the inner moving plate 36 will move inward and the limiting plate 38 will be inserted into the slot. This ensures the positioning effect of the optical device.
[0022] In some embodiments, a second screw 40 is threadedly connected to the constraint ring 30. A pressure ring 42 is fitted onto the second screw 40, and an inner top spring 41 is fitted onto the second screw 40. The inner end of the inner top spring 41 abuts against the pressure ring 42, and the outer end of the inner top spring 41 abuts against the inner end of the nut of the second screw 40. A limit rod 39 is welded onto the limiting plate 38 and passes through the pressure ring 42. When moving the inner moving plate 36, the pressure ring 42 needs to be pulled outward first. After the inner moving plate 36 moves into place, the pulling force on the pressure ring 42 is released. Afterward, the limit rod 39 passes through the pressure ring 42 to ensure the stability of the limiting plate 38 inserted into the slot.

Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope.
