Description

Technical Field

[0001] The invention relates to the technical field of production and processing of driving recorders, and in particular to a lens fine grinding device for driving recorders. Background Art

[0002] With the development of the times, more and more people choose to travel by car, and there are more and more vehicles on the road. Most people will equip their cars with a driving recorder, which is an instrument that records images, sounds and other related information while the vehicle is driving. After the driving recorder is installed, the video images and sounds of the entire driving process of the car can be recorded, which can provide evidence for traffic accidents. People who like self-driving tours can also use it to record the process of conquering difficulties and obstacles. When driving, they can record videos while walking, and record the time, speed and location in the video at the same time. It is quite a "black box". It can also be used as a DV at home to shoot the fun of life, or as a home monitoring system. It can also be used for parking monitoring at ordinary times. After installing a driving recorder, the video data cannot be cropped. If it is cropped, it cannot provide help after the accident occurs. The driving recorder often needs to be equipped with corresponding lenses. Therefore, with the increase in demand, more and more driving recorder lenses need to be produced. In the process of producing driving recorder lenses, in order to make the lenses smoother and more transparent, it is necessary to polish the lenses. Therefore, a lens fine grinding device for driving recorders is introduced.

[0003] Most of the existing lens fine-grinding devices for driving recorders on the market currently only fix the lens to be polished at a specific position, press the polishing device on the lens to be polished for polishing. After polishing one side, the operator manually turns over the lens to be polished, and then polishes the other side. It is impossible to polish both sides of the lens at the same time, and the polishing efficiency is low. It is also impossible to well control the polishing equipment to polish both sides of the lens to be polished to the same degree. The polishing effect is not ideal, and most of the existing lens fine-grinding devices for driving recorders on the market do not clean and collect the debris generated during the lens polishing process. A lot of manpower is required for subsequent cleaning, and there is a high possibility that a large amount of lens debris will scratch the workers during the cleaning process. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art, and a lens fine grinding device for a driving recorder is proposed. The device can grind both sides of the lens at the same time, eliminating the need for the operator to manually turn over the lens to be polished, saving manpower and improving the grinding efficiency. By grinding both sides of the lens at the same time, the grinding equipment can also be better controlled to grind both sides of the lens to the same degree, making the grinding effect more ideal. In addition, the device cleans and collects the debris generated during the grinding process of the lens, reducing the workload of subsequent manual cleaning and reducing the possibility of lens debris scratching workers during the cleaning process.

A connecting shaft 2274 connected to one end of the inner top wall of the two fixed strips 2273 away from the strip plate 2271, and two ventilation slots 2272 respectively opened at the lower parts of the front and rear sides of the strip plate 2271, the ends of the two connecting shafts 2274 away from the arc plate 221 are fixedly connected to the fan 2275, the left and right ends of the strip plate 2271 are respectively arranged in the middle of the two track slots 226, the ends of the two connecting shafts 2274 close to the arc plate 221 are fixedly connected to the bevel gear 2276, the two bevel gears 2276 are respectively meshed with the two arc-shaped oblique racks 225, the lower parts of the left and right ends of the strip plate 2271 are provided with grooves 2277 on the front and rear sides, and the two arc-shaped oblique racks 225 are respectively arranged in the middle of the grooves 2277 at the lower parts of the left and right ends of the strip plate 2271.The lower side of the shell 21 is fixedly connected to the bottom box 3, and the interior of the bottom box 3 is slidably connected to the dust collecting drawer 4. When the debris generated during grinding falls on the upper side of the shell 21, the motor 224 is started to drive the moving gear 223 to rotate. Because the moving gear 223 is meshed with the rack 222, the rotation of the moving gear 223 will carry the motor 224 and the blowing and scraping component 227 to move back and forth along the track groove 226. Because there will be not only debris but also glass dust during the grinding process, only the strip plate 2271 is close to the upper side of the shell 21 for scraping and cleaning. Small dust may be adsorbed on the upper side of the shell 21, and scraping cleaning cannot be completely cleaned, and the bevel gear 2276 and the arc-shaped bevel rack 225 interact with each other. The bevel gear 2276 drives the fan 2275 to rotate through the connecting shaft 2274 as the blowing and scraping component 227 moves, so that the fan 2275 blows air into the strip plate 2271, and the air blows out from the ventilation slot 2272. The lens dust on the upper side of the shell 21 can be blown and cleaned during the movement of the blowing and scraping component 227. As a result, the dust adsorbed on the upper side of the shell 21 can be cleaned into the shell 21 through the notch 23, and filtered through the filter hole 24, and falls into the dust collection drawer 4 inside the bottom box 3 on the lower side of the shell 21, which is convenient for pulling out the dust collection drawer 4 for unified cleaning. The rear side of the shell 11 is rotatably connected with an operating cover 5, which is convenient for the staff to operate and repair the device.

[0013] Working principle: Before using the device, place the device at the desired position, open the operating cover 5 through the handle on the operating cover 5, place the lens to be polished on the upper side of the lower grinding plate 1883, and adjust the fan grinding plate 1886 according to the lens to be polished. When the lens to be polished is larger than the lower grinding plate 1883, start the motor 1881 to drive the threaded rod 1882 to rotate. Before starting the motor 1881, adjust the limit lock sleeve 1888 according to the required adjustment range of the fan grinding plate 1886 and the moving range of the threaded sleeve 1885 on the threaded rod 1882, and rotate the limit lock sleeve 1888 on the threaded rod 1882 to control the moving range of the threaded sleeve 1885. When the motor 1881 drives the threaded rod 1882 to rotate, the lower grinding plate 188 3 is fixedly connected to the filter plate 187 through the fixed connecting rod 1884, so the threaded sleeve 1885 can only move between the two limit lock sleeves 1888 along the threaded rod 1882 under the restriction of the connecting rotating rod 1887 and the fan grinding plate 1886, so that the threaded sleeve 1885 rises along the threaded rod 1882, and pushes the fan grinding plate 1886 through the connecting rotating rod 1887, so that the fan grinding plate 1886 is unfolded, so as to better adapt to the lens that needs to be polished and is larger than the lower grinding plate 1883, which is convenient for subsequent comprehensive polishing. Then, the electric push rod 1710 on the main gear ring 176 is started, so that the electric push rod 1710 pushes the push plate 1711, and pushes the clamping plate 1712 through the spring rod 1713, so that multiple clamping plates 1712 clamp the lenses that need to be polished at the same time, and the lenses are polished. The spring rod 1713 can make the clamping plate 1712 have a certain buffer when pushing and clamping the lens to be polished, so as to prevent the clamping plate 1712 from excessively squeezing the lens to be polished and damaging the lens to be polished, and start the hydraulic rod 165, so that the hydraulic rod 165 pushes the polishing cover 166 downward and lightly covers the lens to be polished, and finally start the motor 172 to drive the main gear 173 to rotate, thereby driving the main gear ring 176 to rotate, and then driving the sub-gear 2 14 and the main gear ring 176 to rotate through the transmission gear 2 179, and then the sub-gear 2 14 drives the sub-gear 1 13 and the sub-gear 3 15 and the sub-gear 2 14 to rotate through the main shaft 12, and then the sub-gear 1 13 drives the sub-gear ring 183 to rotate through the transmission gear 3 186, thereby making The main gear ring 176 rotates in the opposite direction to the auxiliary gear ring 183 and the gear ring cover 163, thereby improving the grinding efficiency. The debris generated during grinding falls through the filtration of the filter plate 187. The filter plate 187 can also prevent the lens to be polished from accidentally falling. As a result, the device can grind both sides of the lens at the same time, eliminating the need for the operator to manually turn over the lens to be polished, saving manpower and improving the grinding efficiency. By grinding both sides of the lens at the same time, the grinding equipment can be better controlled to grind both sides of the lens to be polished to the same degree, making the grinding effect more ideal. When the debris generated during grinding falls on the upper side of the shell 21, the motor 224 is started to drive the moving gear 223 to rotate. Because the moving gear 223 is engaged with the rack 222,Therefore, under the rotation of the moving gear 223, the motor 224 and the blowing and scraping component 227 will be carried to reciprocate along the track groove 226. Because there will be not only debris but also glass dust in the grinding process, if the strip plate 2271 is only close to the upper side of the shell 21 for scraping and cleaning, fine dust may be adsorbed on the upper side of the shell 21, and the scraping cleaning cannot be completely cleaned. The bevel gear 2276 and the arc-shaped bevel rack 225 are meshed with each other. Therefore, as the blowing and scraping component 227 moves, the bevel gear 2276 drives the fan 2275 to rotate through the connecting shaft 2274, so that the fan 2275 moves toward the strip plate 227. 1, the wind blows out from the ventilation slot 2272, and the lens dust on the upper side of the shell 21 can be blown and cleaned during the movement of the blowing and scraping component 227, so that the dust adsorbed on the upper side of the shell 21 can be cleaned into the shell 21 through the notch 23, and filtered through the filter hole 24, and fall into the dust collection drawer 4 inside the bottom box 3 on the lower side of the shell 21, so that it is convenient to pull out the dust collection drawer 4 for unified cleaning later, thereby cleaning and collecting the debris generated during the lens grinding process, reducing the workload of subsequent manual cleaning, and also reducing the possibility of lens debris scratching workers during the cleaning process.
