Description

Technical Field

[0001] This utility model relates to the field of lens barrel cleaning technology, and in particular to a lens barrel inner barrel cleaning device. Background Technology

[0002] In the field of optical instrument manufacturing and maintenance, the cleanliness of the inner wall of the lens barrel, as the carrier structure of the core optical component, directly determines the stability of the optical path and the imaging quality. Just like the "field of view channel" of a camera lens, any tiny dirt or residue may lead to a decrease in light transmittance and seriously affect the performance of the equipment. With the annual increase in market demand for optical equipment such as smartphone camera modules and medical endoscopes, higher requirements are placed on the precision, efficiency and safety of cleaning the inner barrel of the lens barrel.

[0003] Traditional devices often lack a feeding structure, making it easy for the cleaning components to deviate in position when they extend into the inner barrel of the microscope tube. Furthermore, the cleaning process often relies on manual operation or simple mechanical transmission, which not only makes it difficult to achieve thorough cleaning but also results in extremely low cleaning efficiency. In addition, incomplete cleaning often leads to a decline in the performance of the microscope tube. In terms of fixation, traditional devices often use manual clamping or simple buckles for fixation, and lack protective design. Improper force control during fixation can easily lead to problems such as insecure fixation causing the microscope tube to shift during cleaning and affecting the cleaning effect, or excessive force causing physical damage to the microscope tube and shortening its service life. At the same time, manual fixation is cumbersome, further reducing the efficiency and safety of the overall cleaning operation. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cleaning device for the inner cylinder of a microscope tube.

[0005] This utility model is achieved using the following technical solution: a cleaning device for the inner barrel of a microscope tube, comprising a mounting base, a first support plate fixedly connected to the top of the mounting base, a limit rod fixedly connected to the right side of the first support plate, and a second support plate fixedly connected to the top of the mounting base, and further comprising:

[0006] The cleaning mechanism includes an electric push rod fixedly connected to the right side of the second support plate, a sliding frame slidably connected to the outside of the limiting rod, and a cleaning brush provided on the left side of the sliding frame;

[0007] The fixing mechanism includes a rotating disk rotatably connected inside a first support plate, a fixing block slidably connected inside the rotating disk, and an anti-slip pad fixedly connected to the outside of the fixing block.

[0008] As a further improvement to the above solution, the end of the limiting rod away from the first support plate is fixedly connected to the left side of the second support plate, the sliding frame is fixedly connected to the left end of the electric push rod, a servo motor is fixedly connected to the outside of the sliding frame, and a transmission rod is fixedly connected to the output end of the servo motor.

[0009] The above technical solution fixes the two ends of the limiting rod to the first support plate and the second support plate respectively, forming a rigid guide rail to ensure that the sliding frame moves accurately along a straight line; the design of the electric push rod directly driving the sliding frame reduces the energy loss in the intermediate links and makes the forward and backward movement of the cleaning brush more reliable.

[0010] As a further improvement to the above solution, the transmission rod is rotatably connected inside the sliding frame, a first bevel gear is fixedly connected to the outside of the transmission rod, and a rotating rod is rotatably connected inside the sliding frame.

[0011] Through the above technical solution, the independently set rotating pair ensures that the transmission rod is only responsible for rotational motion and does not participate in linear displacement, avoiding jamming or wear problems caused by compound motion; the bevel gear placed inside the sliding frame can effectively prevent dust and dirt, and extend its service life.

[0012] As a further improvement to the above solution, a second bevel gear is fixedly connected to the outside of the rotating rod, the second bevel gear meshing with the first bevel gear, and the cleaning brush is fixedly connected to the outside of the rotating rod.

[0013] As a further improvement to the above solution, a drive motor is fixedly connected to the back of the first support plate, and a worm gear is fixedly connected to the output end of the drive motor. The worm gear is rotatably connected inside the first support plate.

[0014] Through the above technical solution, the worm gear transmits power to the toothed retaining ring, and its self-locking function ensures the stability of the fixation after the fixing is completed.

[0015] As a further improvement to the above solution, a toothed fixing ring is fixedly connected to the outside of the rotating disk, the toothed part of the toothed fixing ring meshes with the worm gear, and a connecting rod is rotatably connected inside the fixing block.

[0016] As a further improvement to the above solution, an arc-shaped groove is provided inside the first support plate, and a sliding block is slidably connected inside the arc-shaped groove, with the connecting rod rotatably connected inside the sliding block.

[0017] Through the above technical solution, the arc-shaped guide rail forces the sliding block to run along a predetermined trajectory, compensating for the center offset of different diameter mirror tubes. At the same time, it automatically adjusts its size by utilizing the geometric characteristics of the arc surface, ensuring compatibility from thin-walled tubes to thick-walled tubes and expanding the applicability of the equipment.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention utilizes the coordinated operation of an electric push rod, a limiting rod, a sliding frame, a servo motor, a transmission rod, a first bevel gear, a second bevel gear, a rotating rod, and a cleaning brush in its cleaning mechanism. The electric push rod drives the sliding frame to move stably along the limiting rod, causing the cleaning brush to precisely extend into the inner barrel of the lens. Simultaneously, the servo motor drives the transmission rod to rotate, and through the meshing transmission of the first and second bevel gears, the rotating rod drives the cleaning brush to rotate. This achieves efficient and thorough cleaning of the inner barrel of the lens, effectively improving cleaning efficiency and quality, and avoiding the problem of lens performance being affected by incomplete cleaning.

[0020] This invention utilizes the orderly operation of a drive motor, worm gear, toothed fixing ring, rotating disk, connecting rod, sliding block, arc groove, fixing block, and anti-slip pad in a fixing mechanism. The drive motor rotates the worm gear, which in turn rotates the rotating disk through the meshing of the worm gear and toothed fixing ring. The rotating disk, via the connecting rod, causes the sliding block to slide along the arc groove, thereby moving the fixing block towards the lens barrel. This allows the anti-slip pad to adhere to the outer wall of the lens barrel, achieving stable and non-destructive fixing of the lens barrel. This ensures that the lens barrel will not shift during cleaning, guaranteeing the stability and safety of the cleaning process, avoiding physical damage to the lens barrel during fixing, and extending the service life of the lens barrel.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] Example:

[0030] Please combine Figure 1-5 This embodiment of a lens barrel inner tube cleaning device includes a mounting base 1, a first support plate 11 fixedly connected to the top of the mounting base 1, a limit rod 12 fixedly connected to the right side of the first support plate 11, and a second support plate 13 fixedly connected to the top of the mounting base 1. It also includes:

[0031] The cleaning mechanism 2 includes an electric push rod 201 fixedly connected to the right side of the second support plate 13, a sliding frame 202 slidably connected to the outside of the limiting rod 12, and a cleaning brush 208 provided on the left side of the sliding frame 202.

[0032] The fixing mechanism 3 includes a rotating disk 303 rotatably connected inside the first support plate 11, a fixing block 305 slidably connected inside the rotating disk 303, and an anti-slip pad 306 fixedly connected to the outside of the fixing block 305.

[0033] The end of the limiting rod 12 away from the first support plate 11 is fixedly connected to the left side of the second support plate 13. The sliding frame 202 is fixedly connected to the left end of the electric push rod 201. A servo motor 203 is fixedly connected to the outside of the sliding frame 202. A transmission rod 204 is fixedly connected to the output end of the servo motor 203.

[0034] The transmission rod 204 is rotatably connected inside the sliding frame 202. The first bevel gear 205 is fixedly connected to the outside of the transmission rod 204, and the rotating rod 206 is rotatably connected inside the sliding frame 202.

[0035] A second bevel gear 207 is fixedly connected to the outside of the rotating rod 206. The second bevel gear 207 meshes with the first bevel gear 205. A cleaning brush 208 is fixedly connected to the outside of the rotating rod 206.

[0036] Activating the electric push rod 201 causes the sliding frame 202 to move stably along the limit rod 12 towards the lens barrel, thereby extending the cleaning brush 208 into the inner barrel of the lens barrel. Subsequently, activating the servo motor 203 fixed externally to the sliding frame 202 causes the transmission rod 204 fixed at the output end of the servo motor 203 to rotate, which in turn drives the first bevel gear 205 fixed externally to rotate synchronously, thereby driving the second bevel gear 207 to rotate, ultimately causing the rotating rod 206 to rotate inside the sliding frame 202, and finally driving the cleaning brush 208 to rotate.

[0037] A drive motor 301 is fixedly connected to the back of the first support plate 11, and a worm gear 302 is fixedly connected to the output end of the drive motor 301. The worm gear 302 is rotatably connected inside the first support plate 11.

[0038] A toothed retaining ring 304 is fixedly connected to the outside of the rotating disk 303. The toothed part of the toothed retaining ring 304 meshes with the worm gear 302. A connecting rod 307 is rotatably connected inside the fixing block 305.

[0039] The first support plate 11 has an arc-shaped groove 308 inside, and a sliding block 309 is slidably connected inside the arc-shaped groove 308. The connecting rod 307 is rotatably connected inside the sliding block 309.

[0040] When the drive motor 301 is started, the worm gear 302 will rotate inside the first support plate 11, and drive the toothed fixing ring 304 and the rotating disk 303 fixed thereto to rotate inside the first support plate 11. When the rotating disk 303 rotates, it will drive the sliding block 309 to slide in the arc groove 308 through the connecting rod 307, thereby driving the fixing block 305 to move closer to the lens barrel inside the rotating disk 303 until the anti-slip soft pad 306 fixed outside the fixing block 305 is tightly attached to the outer wall of the lens barrel, thus completing the fixing of the lens barrel.

[0041] The implementation principle of the lens barrel cleaning device in this embodiment is as follows: Before cleaning, the lens barrel needs to be fixed. At this time, the drive motor 301 fixed on the back of the first support plate 11 is started, which will drive the worm gear 302 fixed at the output end of the drive motor 301 to rotate inside the first support plate 11. Since the worm gear 302 and the toothed part of the toothed fixing ring 304 fixed to the outside of the rotating disk 303 mesh with each other, the rotation of the worm gear 302 will drive the toothed fixing ring 304 and the rotating disk 303 fixed thereto to rotate inside the first support plate 11. 3. The fixed block 305 is slidably connected inside. The connecting rod 307 inside the fixed block 305 is rotatably connected to the external side of the sliding block 309. The sliding block 309 is slidably connected in the arc groove 308 opened inside the first support plate 11. When the rotating disk 303 rotates, the connecting rod 307 will drive the sliding block 309 to slide in the arc groove 308, thereby driving the fixed block 305 to move closer to the lens barrel inside the rotating disk 303 until the anti-slip soft pad 306 fixed outside the fixed block 305 is tightly attached to the outer wall of the lens barrel, thus completing the fixation of the lens barrel.

[0042] After fixing, the electric push rod 201 fixedly connected to the right side of the second support plate 13 is activated. The left end of the electric push rod 201 is fixedly connected to the sliding frame 202, which is slidably connected to the outside of the limiting rod 12. Driven by the electric push rod 201, the sliding frame 202 will move steadily along the limiting rod 12 towards the lens barrel until the cleaning brush 208 fixed to the outside of the left rotating rod 206 of the sliding frame 201 extends into the inner barrel of the lens barrel. Then, the servo motor 203 fixed to the outside of the sliding frame 202 is activated. The transmission rod 204 fixed at the output end of the servo motor 203 will rotate accordingly. The transmission rod 204 is rotatably connected inside the sliding frame 202, and the first bevel gear 205 fixed outside it will also rotate synchronously. Since the first bevel gear 205 and the second bevel gear 207 fixed outside the rotating rod 206 mesh with each other, the rotation of the first bevel gear 205 will drive the second bevel gear 207 to rotate, thereby causing the rotating rod 206 to rotate inside the sliding frame 202, and finally driving the cleaning brush 208 to rotate, so as to thoroughly clean the inner barrel of the lens barrel.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
