A spray cleaning module is disposed on the base and is used to clean and remove dirt from the grating ruler to be cleaned.

[0006] Optionally, the camera module includes an external video interface and a first camera. Along the movement direction of the base, the first camera is disposed at the front end of the base and is used to search for the cleaning points on the grating ruler; the first camera is connected to the external video interface.

[0007] Optionally, the camera module also includes a second camera, which is mounted on the base and faces the grating ruler to be cleaned. The second camera is used to locate the points to be cleaned on the grating ruler.

[0011] Optionally, around the axis of the spray cleaning seat, each of the nozzles is respectively disposed on the top surface and two sides of the spray cleaning seat, so that the effective spraying area of ​​each nozzle is staggered and covers the entire area to be cleaned.

[0012] Optionally, a flow channel regulating valve is also provided at the inlet end of the cleaning channel, and the flow channel regulating valve is provided with a first conveying pipe, a second conveying pipe and a suction pipe.

[0013] Optionally, the flow channel regulating valve includes a valve body, in which a valve core for switching flow channels is rotatably disposed. Along the axial direction of the valve body, a first connecting pipe connected to the cleaning flow channel is disposed on the bottom end face of the valve body.

[0015] Compared with the prior art, this application has the following beneficial effects: This application includes a base on which a camera module and a spray cleaning module are mounted. The camera module is used to search for and locate the points to be cleaned on the grating ruler to be cleaned. The spray cleaning module is used to clean and remove the stains from the grating ruler to be cleaned.

[0016] In use, the entire device is bolted to the sliding device of the machine tool. When the grating ruler needs to be cleaned, the cleaning condition inside the grating ruler is first observed through the camera module. The real-time image captured is uploaded to the control center. The staff judges the point to be cleaned inside the grating ruler through the real-time image. Then, the entire cleaning device is controlled to move to the point to be cleaned through the machine tool's traveling device. During the movement, the camera module judges whether the entire cleaning device has moved to the correct position. When the staff judges that the movement has been in place, the machine tool is stopped. At this time, the stains on the grating ruler are cleaned by the spray cleaning module. At the same time, the cleaned stains are extracted and discharged, thereby achieving the cleaning of the grating ruler. Compared with the prior art, this application can achieve all-round cleaning of the dirt inside the grating ruler without disassembling it during cleaning. At the same time, it can achieve automatic blowing and tin spraying without manual operation of the cleaning equipment, thus minimizing the cleaning difficulty of the grating ruler. Secondly, the cleaning device described in this application does not require the removal of the grating ruler when cleaning it. This not only avoids the cumbersome procedure of disassembling and assembling the grating ruler, which is beneficial to improving cleaning efficiency, but also avoids damage to its components during disassembly and assembly, thereby ensuring its detection accuracy. Finally, during the cleaning process, this application can not only clean each stain point inside the grating ruler one by one, but its cleaning head can also penetrate deep into the grating ruler, which can effectively improve the cleaning effect and avoid stain residue.

[0018] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] Implementation Method 1 Reference Figures 1 to 4This embodiment, as an optional embodiment of this application, discloses a cleaning device for a grating ruler, including a base 1 and a camera module 2. The base 1 has several connecting screw holes at its bottom, and connecting bolts are installed in the connecting screw holes. Through the connecting bolts, the base 1 is connected to the moving parts of an external machine tool to realize the position adjustment of the entire cleaning device. The camera module 2 includes an external video interface 201, a first camera 202, and a second camera 203. The external video interface 201 is located on the lower side of the base 1. The base 1 is generally elongated. Along the length of the base 1, the first camera 202 is located at one end of the base 1. It should be noted that the movement direction of the base 1 is based on the movement direction of the base 1 during cleaning. In order to ensure the positioning effect of the point to be cleaned, the first camera 202 needs to be set at the front end of the base 1, that is, the installation point of the first camera 202 is selected based on the movement direction of the base 1 during cleaning. Furthermore, a mounting groove 4 is provided on the top surface of the base 1. The mounting groove 4 is arranged along the length direction of the base 1. A mounting hole is provided at the bottom of the mounting groove 4. The second camera 203 is disposed in the mounting hole. The connecting lines of the first camera 202 and the second camera 203 are electrically connected to the external video interface 201 respectively to upload the captured images. It should be noted that both the first camera 202 and the second camera 203 are cameras with a light source auxiliary module; In the above structure, the first camera 202 is disposed at the front end of the base 1, and is mainly used to search for the cleaning points on the grating ruler to be cleaned in the uncleaned area of ​​the grating ruler; the second camera 203 is located on the top surface of the base 1, facing the internal space of the grating ruler. Therefore, the second camera 203 can accurately position the base 1 directly below the cleaning point, thereby achieving positioning cleaning; the cooperation of the first camera 202 and the second camera 203 can realize the search and positioning of the cleaning points, thereby realizing the point-to-point cleaning of each cleaning point, effectively avoiding omissions and improving the cleaning effect; Secondly, through the camera, staff can clearly observe the stains inside the grating ruler. This not only allows for secondary observation of the cleaning effect to improve cleaning quality, but also enables the prediction of the type and difficulty of cleaning stubborn stains, so as to take corresponding cleaning methods and further improve the cleaning quality.

[0021] Furthermore, the base 1 is provided with a plurality of guide rollers 5, and each guide roller 5 is disposed on both sides of the mounting groove 4 along the axial direction of the mounting groove 4. The guide roller 5 can effectively reduce the friction between the cleaning device and the grating ruler. On the one hand, it can prevent excessive wear of the base 1 and the internal structure of the grating ruler, which is beneficial to protecting the detection accuracy of the grating ruler. On the other hand, the guide roller 5 can effectively reduce the frictional resistance of the cleaning device, making the adjustment of the equipment smoother. Furthermore, the cleaning device also includes a spray washing module 3, which includes a spray washing base 6. A cleaning channel 7 is provided on the base 1. A connector is provided at the inlet end of the spray washing base 6, and the spray washing base 6 is connected to the outlet end of the cleaning channel 7 through the connector. Several nozzles 8 are connected in parallel on the spray washing base 6. Around the axis of the spray washing base 6, each nozzle 8 is respectively provided on the top surface and two sides of the spray washing base 6, so that the effective spray washing area of ​​each nozzle 8 is staggered and covers the entire area to be cleaned. Specifically, the spray washing base 6 has a cubic structure, and nozzles 8 are provided on the top surface and two sides of the spray washing base 6; Since the entire base 1 is inserted into the grating ruler during installation, by setting each nozzle 8 in a different direction, each nozzle 8 corresponds to one side of the grating ruler, thus covering the entire surface of the grating ruler to be cleaned, thereby effectively avoiding cleaning dead corners and also avoiding resource waste caused by overlapping cleaning areas of nozzle 8. Secondly, the above-mentioned structural design can simplify the structure of the entire spray washing module 3 as much as possible while ensuring the cleaning effect, thereby improving the reliability and stability of the spray washing device; and the simplified structure can reduce the size of the equipment, thereby adapting to the internal space of the grating ruler, avoiding movement interference with the internal structural components of the grating ruler, and thus preventing collisions, which is beneficial to protecting the internal components of the grating ruler.

[0022] Furthermore, a flow channel regulating valve 9 is provided at the inlet end of the cleaning flow channel 7. The flow channel regulating valve 9 includes a valve body 901 and a valve core 902, wherein the valve core 902 is rotatably disposed inside the valve body 901. Along the axial direction of the valve body 901, a first connecting pipe 903 is provided on the bottom end face of the valve body 901, and a second connecting pipe 904, a third connecting pipe 905 and a fourth connecting pipe 906 are provided on the outer circumferential surface of the valve body 901. The first connecting pipe 903 is connected to the inlet end of the cleaning channel 7, the inlet end of the second connecting pipe 904 is connected to the first conveying pipe 10, the inlet end of the third connecting pipe 905 is connected to the second conveying pipe 11, and the inlet end of the fourth connecting pipe 906 is connected to the suction pipe 12. A switching flow channel 907 is provided on the valve core 902. The switching flow channel 907 is arranged in an L-shape. One end of the switching flow channel 907 is coaxial with the first connecting pipe 903, and the other end is arranged along the radial direction of the valve core 902. The valve body 901 is also provided with a rotating handle or servo motor connected to the valve core 902; It should be noted that, among the first delivery pipe 10, the second delivery pipe 11 and the suction pipe 12, the first delivery pipe 10 and the second delivery pipe 11 can be used to deliver cleaning agents, cleaning water, or high-pressure air for purging, and can be flexibly adjusted according to the cleaning situation. Meanwhile, the suction tube 12 is generally used to extract residual stains and water stains; The above-mentioned flow channel switching device can deliver a variety of different cleaning agents, thereby enriching the cleaning methods. At the same time, the suction pipe 12 can also remove the residual cleaning agent or cleaning water after cleaning, thereby avoiding secondary pollution caused by cleaning. Accordingly, this application also discloses a method for using the aforementioned cleaning device, including the following steps: S1. Install the cleaning device onto the connecting plate of the machine tool moving parts using connecting screws; S2. Connect the external video interface and each delivery pipeline; at the same time, adjust the cleaning device to the extreme position of one end of the grating ruler. S3. View the real-time images fed back by the first and second cameras in real time through an external video device; remotely observe and determine the cleaning point through the image of the first camera; after determining the cleaning point, position the cleaning device directly below the cleaning point through the second camera. S4. The cleaning agent is delivered to each nozzle through the first or second delivery pipe. After the cleaning agent has completely soaked the stains, the supply of cleaning agent is cut off, and the pipeline is switched through the flow channel regulating valve. S5. After the pipeline switching is completed, high-pressure air or high-pressure cleaning water is delivered into the nozzle to perform high-pressure spraying on the softened stains. High-pressure spraying can not only effectively remove stains, but also blow out the impurities and particles attached to the grating ruler after cleaning, thereby improving the cleaning effect. S6. Switch the pipeline again through the flow channel regulating valve, connect the vacuum cleaner interface to the nozzle, and use the vacuum cleaner to suck out the residual dirt after cleaning, thereby realizing the cleaning residue removal operation inside the grating ruler. S7. Observe the cleaning effect through the second camera. If the cleaning effect is not good, repeat steps S4-S6 multiple times or repeat the above steps after changing the cleaning agent. If the cleaning effect is good, control the cleaning device to the next cleaning point. Compared with the prior art, this application can achieve all-round cleaning of the dirt inside the grating ruler without disassembling it during cleaning. At the same time, it can achieve automatic blowing and tin spraying without manual operation of the cleaning equipment, thus minimizing the cleaning difficulty of the grating ruler. Secondly, the cleaning device described in this application does not require the removal of the grating ruler when cleaning it. This not only avoids the cumbersome procedure of disassembling and assembling the grating ruler, which is beneficial to improving cleaning efficiency, but also avoids damage to its components during the disassembly and assembly process, thereby ensuring its detection accuracy. Finally, during the cleaning process, this application can not only clean each stain point inside the grating ruler one by one, but its cleaning head can also penetrate deep into the grating ruler, which can effectively improve the cleaning effect and avoid stain residue. Meanwhile, this application can soften the stains inside the grating ruler with a cleaning agent, and also rinse the softened stains with high-pressure air or high-pressure cleaning water, thereby improving the cleaning effect of the grating ruler. At the end of the cleaning, the residual water stains can be extracted with a suction tube, thereby removing the cleaning residue inside the grating ruler and avoiding secondary pollution.
