Description

Technical Field

[0001] This utility model relates to a surface treatment device, and more particularly to a surface treatment device for an optical lens barrel. Background Technology

[0002] Optical tubes are key components in optical instruments such as endoscopes, microscopes, and telescopes, and their surface quality directly affects the performance and imaging quality of the optical system. Therefore, surface treatment technology for optical tubes is particularly important.

[0003] Surface treatment of optical lens barrels typically includes cleaning and polishing processes. The purpose is to remove surface contaminants, scratches, and defects, improve surface smoothness and flatness, and thus enhance optical performance. However, existing optical lens barrel surface treatment methods have some shortcomings. While equipment can effectively address surface contaminants, polishing methods for scratches often rely on manual operation. Scratches are treated manually or using polishing machines, which is not feasible for batch processing of lens barrels. This results in low efficiency and makes it difficult to ensure consistent treatment results for each product. Utility Model Content

[0004] To overcome the shortcomings of traditional lens barrel surface treatment, which, while effectively addressing surface contaminants using relevant equipment, often relies on manual polishing methods for scratch removal, making batch processing of lens barrels impossible. This results in low efficiency and difficulty in ensuring consistent processing results for each product. The purpose of this invention is to provide a surface treatment device for optical lens barrels to solve one of the aforementioned problems.

[0005] Technical Solution: A surface treatment device for an optical lens barrel includes a base plate, a base, a liquid tank, a housing, an ultrasonic cleaning tank, an ultrasonic module, a lower connecting groove, a transmission component, a side cylinder, a diverter valve, a central connecting pipe, a pump, a diverter connector, a connecting pipe, a drain pipe, a hanging system, and hanging fixtures. A base is located on one side of the top of the base plate. The housing is symmetrically located on the front and rear sides of the upper part of the base. A liquid tank is located on the left side of the base, used to store a sand-mixing liquid for cleaning the lens barrel surface. An ultrasonic cleaning tank is located on the right side of the base, with an ultrasonic module installed on one side. A lower connecting groove is fixed above the liquid tank, and a diverter valve passes through the lower part of the lower connecting groove. A pump is located on one side wall of the liquid tank, with its output end connected to the diverter valve and its input end extending downwards into the lower inner space of the liquid tank. A drain pipe is vertically located above the diverter valve, which has multiple liquid flow channels. The drain pipe is connected to a certain pipe inside the diverter valve. The lower connecting groove... The system is equipped with a transmission component and a drain outlet at the bottom of the lower receiving tank. Symmetrical side cylinders are mounted on the transmission component, each with multiple connecting pipes on its inner wall. Each side cylinder has a flow divider at its lower part. A flow divider valve connects to two flow dividers via a central connecting pipe. Vertical connecting pipes are mounted on the upper part of each flow divider, connecting to the flow dividers on the same side cylinder. Multiple nozzles are mounted on the drain pipe and connecting pipes. The mixed sand liquid in the tank is pumped out and transmitted through different flow channels of the flow divider valve to the two flow dividers and the drain pipe, and then sprayed out through the nozzles on the drain pipe and connecting pipe. The side cylinders move in opposite directions within the lower receiving tank via the transmission component. When the two side cylinders move inwards and contact each other, they overlap and form a hollow cylindrical shape. A hanging system is mounted on the bottom plate, equipped with hanging fixtures. The hanging system drives the hanging fixtures to pass sequentially through the side cylinders and the ultrasonic cleaning tank for processing.

[0006] Furthermore, the hanging system includes columns, rails, transmission chains, sliders, cylinders, clamps, hanging fixtures, support blocks, hanging blocks, clamping fixtures, sliding rods, and pressure blocks. Two columns are located on the rear side of the base plate, with a rail between the upper parts of the columns. The path at the front of the rail is directly above the lower receiving groove and the ultrasonic cleaning tank. A transmission chain is located in the upper part of the rail, circulating within the rail via a power component. Several push blocks are spaced along the transmission chain. Multiple sliders are slidably and evenly spaced along the inner side of the lower part of the rail, each pushed by a push block on the transmission chain to achieve circulation on the rail. Each slider is vertically mounted with a cylinder, and a clamp is fixedly connected to the end of the cylinder's movable rod. The hanging fixture is hung within the clamp, consisting of hanging blocks, a hanging frame, and several support blocks set within the hanging frame. The overall hanging fixture is cylindrical, with the support blocks arranged in a ring around the hanging block. The frame is arranged vertically downwards in multiple layers, with a fixed spacing between each layer of support blocks to ensure that each support block can independently support the lens barrel without interfering with each other. The lens barrel is suspended in the holder by the upper hanging blocks, and moves along the track by the movement of the holder, slider, and cylinder. The suspension fixture is equipped with a clamping fixture, which consists of a sliding frame, a sliding rod, and several pressure blocks arranged on the sliding frame. The sliding rod is located at the top of the sliding frame, and its upper part passes through the hanging blocks on the suspension frame. The sliding rod has threads and is fitted with a nut. The pressure blocks are also arranged in a ring in the sliding frame, vertically downwards in multiple layers. The number of pressure blocks in each layer is the same as the number of support blocks in the corresponding layer, forming a one-to-one pair. By moving the sliding frame, the pressure blocks move down to cooperate with the support blocks in the corresponding layer, vertically fixing the lens barrel in the suspension fixture. The position of the clamping fixture is then fixed by the nuts.

[0007] Furthermore, pressure regulating valves are also installed on the pipelines of the drain pipe and the diversion joint.

[0008] Furthermore, it also includes a filter element. A filter element is provided on one side of the liquid tank. The filter element consists of a frame and a filter screen. The filter element is located below the drain outlet of the lower tank. The liquid flowing out of the lower tank will pass through the filter element and then flow into the liquid tank.

[0009] Furthermore, it also includes a cleaning tank and a water receiving side tank. The cleaning tank is located in the area between the liquid tank on the upper part of the base and the ultrasonic cleaning tank. The water receiving side tank is located on the upper part of the cleaning tank near the side cylinder. The water receiving side tank is connected to the internal space of the water receiving tank.

[0010] Furthermore, it also includes a liquid inlet connector. Two liquid inlets are provided on the wall of the liquid tank, and the two liquid inlets are used to introduce the cleaning agent and the solid liquid into the liquid tank respectively.

[0011] Furthermore, both the ultrasonic cleaning tank and the cleaning tank are equipped with a water injection and drainage system.

[0012] The beneficial effects are as follows: This utility model uses a hanging system and hanging fixture to transport lens barrels to be processed in batches and continuously. By introducing the lens barrel into the side barrel, high-speed liquid flow carrying fine particles is evenly impacted on the surface of the lens barrel on the hanging fixture through multi-directionally arranged nozzles, achieving uniform and meticulous surface polishing. After polishing, an ultrasonic cleaning device is used to further treat the lens barrel surface, thoroughly removing any tiny particles and residues that may have been generated during the polishing process, ensuring the cleanliness of the lens barrel surface, and ultimately achieving a high-quality optical lens barrel surface treatment effect.

[0013] This invention features an airflow regulating valve installed on the pipe connecting the inner tube and the drain pipe of the side cylinder. By using airflow to compensate for the pressure of the liquid flow, the stability and uniformity of the liquid flow are ensured, thereby improving the consistency and reliability of the polishing effect. In addition, the airflow regulating valve can effectively reduce the instability of the liquid flow caused by pressure fluctuations, which not only optimizes the polishing process but also improves the stability and working efficiency of the entire system.

[0014] This invention filters the liquid returning to the liquid tank from the lower receiving groove, intercepting larger particles cleaned from the lens barrel, reducing the likelihood of blockages in the various transmission pipelines caused by the cleaned impurities, while maintaining the cleanliness of the polishing fluid to a certain extent, extending the service life of the liquid in the liquid tank, and reducing the frequency of replacement.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: A surface treatment device for an optical lens barrel, such as Figure 1-7 As shown, the system includes a base plate 1; the base plate 1 forms the foundation of the equipment, providing stable support for the entire system. A base 2 is mounted on the base plate 1, and housings 3 are symmetrically arranged on the front and rear sides of the upper part of the base 2, providing a relatively enclosed environment for the polishing process. The liquid tank 21 on the left side of the base 2 is used to store the sand-mixing liquid, which plays a key role in the polishing process. The fine particles it contains can effectively polish the surface of the lens barrel. On the right side of the base 2, an ultrasonic cleaning tank 4 is provided, with an ultrasonic module 41 installed on one side. After the lens barrels are polished, they will be moved here for deep cleaning to remove residual particles and impurities.

[0025] Two inlet connectors 9 are provided on the wall of the liquid tank 21. The two inlet connectors 9 are used to introduce the cleaning agent and the solid liquid into the liquid tank 21 respectively, so as to replenish the polishing liquid in the liquid tank in time. A lower receiving groove 5 is fixedly provided above the liquid tank 21. A diversion valve 53 is carefully installed in the lower part of the lower receiving groove 5. This valve has multiple liquid flow channels inside, which can flexibly control the flow direction and flow rate of the liquid. A liquid pump 54 is configured on one side wall of the liquid tank 21. Its input end extends into the lower part of the liquid tank 21 to ensure that sufficient sand mixing liquid can be extracted. The output end of the liquid pump 54 is closely connected to the diversion valve 53 to deliver the extracted liquid to the diversion valve.

[0026] A drain pipe 56 is vertically installed at the top of the diverter valve 53. It is connected to a certain pipeline inside the diverter valve and is responsible for delivering liquid to the designated nozzle position. Inside the lower receiving groove 5, a transmission component 51 is also installed, which drives the symmetrically arranged side cylinders 52 to move. Multiple connecting pipes 551 are evenly spaced on the inner wall of the side cylinders 52. They are connected to the diverter connector 55 at the bottom to ensure smooth liquid transmission.

[0027] The diversion valve 53 is connected to two diversion joints 55 through the central pipe 531. In this way, the liquid can be accurately delivered to the two side cylinders 52 through the regulation of the diversion valve 53. The upper part of the diversion joint 55 is vertically connected to the connecting pipe 55, which is closely connected to the diversion joint 55 on the same side cylinder 52, forming a complete liquid delivery network.

[0028] Multiple nozzles are cleverly installed on the drain pipe 56 and the connecting pipe 551. They can spray the liquid at high speed and evenly impact the surface of the lens barrel. When the mixed sand liquid in the liquid tank 21 is drawn out by the pump 54, it will be transmitted to the two diversion joints 55 and the drain pipe 56 through different liquid flow channels of the diversion valve 53, and finally sprayed out through the nozzles.

[0029] Driven by the transmission component 51, the side cylinder 52 can move back and forth in opposite directions within the lower groove 5. When the two side cylinders 52 move inward and contact each other, they will cover each other and form a hollow cylindrical shape. This shape can just accommodate the hanging fixture 66 and the mirror tube on it, providing a closed and stable environment for polishing. The base plate 1 is equipped with a hanging system 6, and the hanging fixture 66 is equipped on the hanging system 6. The hanging fixture 66 is driven by the hanging system 6 to pass through the side cylinder 52 and the ultrasonic cleaning tank (4) in sequence to carry out the corresponding processing steps.

[0030] Among them, such as Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the hanging system 6 includes columns; two columns 61 are securely installed on the rear side of the base plate 1. They not only provide solid support for the entire hanging system 6, but also define the installation space of the track 62. The track 62 spans between the upper parts of the columns 61, and its front path is located directly above the lower receiving groove 5 and the ultrasonic cleaning tank 4. This layout facilitates the smooth movement of the hanging fixture 66 and the lens barrel on it between the processing areas.

[0031] Inside the upper part of the track 62, a transmission chain 63 is installed. Driven by a power component, it circulates within the track, providing continuous power for the movement of the hanging fixture 66. Several push blocks are spaced apart on the transmission chain 63. These blocks cooperate with multiple sliders 64 that are slidably and evenly spaced on the lower inner side of the track 62. By pushing the push blocks, the sliders 64 circulate on the track 62.

[0032] like Figure 6 and Figure 7 As shown, each slider 64 is vertically mounted with a cylinder 65, the end of which is firmly connected to a mounting base 651. This mounting base 651 is the mounting point of the hanging fixture 66. The hanging fixture 66 consists of a hanging block 662, a hanging frame, and multiple layers of ring-shaped support blocks 661. The whole fixture has a cylindrical shape. The support blocks 661 are arranged vertically downward in multiple layers, and each layer maintains a fixed spacing. This design ensures that each support block 661 can independently support the lens barrel without interfering with each other.

[0033] The hanging fixture 66 is suspended in the holder 651 by the upper hanging block 662. As the holder, slider 64 and cylinder 65 move, it can move freely on the track 62. In order to fix the lens barrel, the hanging fixture 66 is also equipped with a clamping fixture 67, which consists of a sliding frame, a sliding rod 671 and multiple layers of ring-shaped clamping blocks 672. The sliding rod 671 is located at the upper part of the sliding frame and passes through the hanging block 662 on the hanging frame. The position of the clamping fixture can be easily adjusted by the cooperation of the thread and nut.

[0034] The pressure block 672 and the support block 661 form a one-to-one pair. When it is necessary to fix the lens barrel, simply move the sliding frame to move the pressure block 672 down, so that it can fit tightly with the support block 661 of the corresponding layer, thus fixing the lens barrel vertically in the hanging fixture 66. Finally, by tightening the nut, the position of the clamping fixture 67 can be firmly locked, ensuring that the lens barrel will not loosen or fall off during processing.

[0035] During processing, the hanging fixture is inserted into the bracket 651 at the front left of the track. Driven by the hanging system 6, the bracket 651 carries the hanging fixture 66 and the mirror barrel to be processed into the housing 3 and then transfers it to the right to the side cylinder 52. The track 62 is then stopped, the cylinder 65 is extended downward to the preset height, and then the transmission component 51 is controlled to close the two side cylinders 52. At this time, the hanging fixture 66 is surrounded by the side cylinders 52 and is fitted around the drain pipe 56. The pump 54 is started to extract the mixed sand liquid in the liquid tank 21 and distribute it to the drain pipe 56 and the connecting pipe 551 through the diversion valve 53. Finally, the mixed sand liquid containing fine particles is sprayed onto the mirror barrel at high speed through the nozzles on these pipes. The mixed sand liquid is sprayed onto the surface of the mirror barrel under high pressure, which can effectively remove impurities and minor defects from the surface of the mirror barrel. At the same time, since multiple nozzles act from different angles at the same time, it ensures that the surface of the mirror barrel is subjected to uniform force, which improves the quality and efficiency of polishing. During the polishing process, the flow of the mixed sand liquid not only serves a cleaning function, but also achieves fine polishing of the lens barrel surface through its internal micro-particles, making the lens barrel surface smoother and flatter.

[0036] After polishing, the control system first shuts off the liquid pump 54 to prevent further liquid spraying, which could lead to waste or contamination. Then, the control transmission component 51 separates the two side cylinders 52, exposing the hanging fixture 66 again. The transmission chain 63 on the track 62 then continues to operate, bringing the hanging fixture 66 and the lens barrel on it directly above the ultrasonic cleaning tank 4. The movable rod of the control cylinder 65 extends downwards again, completely immersing the hanging fixture 66 and the lens barrel on it into the cleaning fluid in the ultrasonic cleaning tank 4. The ultrasonic module 41 starts working, generating high-frequency vibrations. Through the cavitation effect of ultrasound, tiny bubbles in the liquid rapidly form and break under the action of ultrasound, generating a powerful impact that can further remove tiny particles and residues from the surface of the lens barrel, ensuring that the cleanliness of the lens barrel surface reaches the highest standard. Ultrasonic cleaning not only improves the cleaning effect but also penetrates into the tiny crevices on the surface of the lens barrel, thoroughly removing dirt from hard-to-reach areas, thus ensuring the high quality of the lens barrel surface.

[0037] Finally, the control system will retract cylinder 65 and lift the hanging fixture 66 and the lens barrel on it out of the ultrasonic cleaning tank 4, completing the entire surface treatment process.

[0038] Example 2: Based on Example 1, such as Figure 5As shown, it also includes a pressure regulating valve 57. A pressure regulating valve 57 is added to the drain pipe 56 and the diverter 55. Each pressure regulating valve 57 is equipped with an airflow connector for connecting to an external high-pressure air source. The airflow is used to compensate for the pressure of the liquid flow transmitted through the connecting pipe 551 and the drain pipe 56. By precisely controlling the airflow, the stability and uniformity of the liquid flow during transmission are ensured. This not only significantly improves the consistency and reliability of the polishing effect, making the workpiece surface smoother and more uniform, but also effectively reduces the instability of the liquid flow caused by pressure fluctuations. This improvement not only optimizes the polishing process but also greatly enhances the stability and efficiency of the entire system, providing a strong guarantee for the smooth operation of the production process.

[0039] Among them, such as Figure 4 As shown, it also includes a filter element 7. The filter element 7 is provided on one side of the liquid tank 21. The filter element 7 is composed of a sturdy frame and a precision filter screen, and is precisely positioned directly below the drain port of the lower receiving tank 5. When the liquid flowing out of the lower receiving tank 5 passes through, it will first be finely filtered by the filter element 7, effectively intercepting larger particles cleaned off the lens barrel. This design not only significantly reduces the risk of blockage of the transmission pipelines by the cleaned impurities, but also greatly maintains the cleanliness of the polishing fluid, thereby extending the service life of the liquid in the liquid tank, reducing the replacement frequency, and improving the stability and efficiency of the overall system.

[0040] In addition, such as Figure 2-4 As shown, it also includes a cleaning tank 8 and a water receiving side channel 81. The cleaning tank 8 is provided in the area between the liquid tank 21 on the upper part of the base 2 and the ultrasonic cleaning tank 4. An additional cleaning tank 8 is provided. On the upper part of the cleaning tank 8, adjacent to the side cylinder 52, there is a water receiving side channel 81, which is closely connected to the internal space of the cleaning tank 8 to form a smooth liquid channel. Through the guidance of the water receiving side channel 81, the polishing station can be effectively connected, and residual liquid or impurities can be captured and guided to prevent them from dripping directly into the equipment, thereby maintaining the cleanliness of the equipment, reducing potential failures caused by the accumulation of impurities, and improving the overall operating efficiency and equipment life.

Therefore, the scope of this disclosure should not be limited to the above embodiments, but should be defined not only by the appended claims, but also by their equivalents.
