Abstract
Description
Technical Field
[0001] This application relates to the field of hard and brittle material cutting, and particularly to a self-cleaning device for cutting navigation. Background Art
[0002] In the photovoltaic field, wire cutting machines are often used to cut hard and brittle materials such as silicon wafers. Many operations still require manual opening of the cutting chamber for observation. However, in some cutting processes, since the cutting chamber cannot be opened, the state of the wire mesh cannot be monitored in real time. This situation is extremely likely to cause problems such as wire mesh breakage, seriously affecting the cutting efficiency and product quality.
[0003] Moreover, during the operation of the wire cutting machine, the mixed substances such as silicon powder generated in the cutting chamber, sprayed cutting fluid, and fog containing cutting fluid make the environment in the cutting chamber extremely harsh. This harsh environment seriously interferes with common sensors, making it impossible for them to accurately detect the state of the wire mesh either. Utility Model Content
[0004] In order to quickly clean the surface of the sensor and improve the anti-interference ability of the sensor, this application provides a self-cleaning device for cutting navigation.
[0005] This application provides a self-cleaning device for cutting navigation, which is used for cleaning the wire mesh monitoring sensor of a hard and brittle material wire cutting machine, and adopts the following technical solutions:
[0006] A self-cleaning device for cutting navigation includes a fixing plate. One side of the fixing plate is provided with a cleaning head for cleaning the sensor. A plurality of cleaning holes are opened on one side of the cleaning head. An air inlet hole and / or a water inlet hole are opened on the side of the cleaning head away from the cleaning holes. The air inlet hole and the water inlet hole are both communicated with the cleaning holes.
[0007] By adopting the above technical solutions, compressed air is introduced through the air inlet hole and water is introduced through the water inlet hole. The compressed air and water respectively enter the cleaning head and are sprayed out from the cleaning holes, realizing the automatic cleaning of the sensor, effectively removing the dirt and impurities on the surface of the sensor, ensuring that the sensor can still work normally in a harsh environment, improving the anti-interference ability of the sensor, and further improving the stability and efficiency of the cutting process.
[0008] Optionally, the center line of the cleaning hole extends in a direction inclined to the side surface of the cleaning head.
[0009] By adopting the above technical solutions, the inclined spraying can better cover the sensor, and by using the gravity and impact force of water, the dirt and impurities on the sensor can be effectively removed, reducing the water stain residue and improving the cleaning efficiency.
[0010] Optionally, a scraping device is provided on the side of the cleaning head away from the fixing plate. The scraping device includes a mounting plate and a scraping strip. An installation groove is formed in the mounting plate, and the scraping strip is located in the installation groove and is detachably connected to the mounting plate.
[0011] By adopting the above technical solution, the scraping strip can initially scrape off dirt and impurities on the sensor. The detachable connection between the scraping strip and the mounting plate enables the scraping strip to be conveniently replaced after wear, reducing the maintenance cost.

A rubber ring is provided on the side of the rotating block close to the scraping device, and the rubber ring abuts against the mounting plate.
[0013] By adopting the above technical solution, the mounting plate can rotate relative to the rotating block, thereby adjusting the angle and position of the scraping strip.

A rotating wheel is rotatably connected to the moving block, and both ends of the elastic member respectively pass through the through holes of the corresponding rotating rods and abut against the mounting plate.
[0017] By adopting the above technical solution, rotating the rotating wheel can drive the elastic member to move, thereby changing the acting forces exerted on the mounting plate by both ends of the elastic member, and further assisting the scraping device to change its angle. The structure is simple and the control is convenient.
[0018] Optionally, the rotating block is rotatably connected to the moving block, and the rotation axis is parallel to the extension direction of the scraping strip. A baffle is provided on the side of the mounting plate close to the cleaning head.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0031] The following further describes the present application in detail with reference to all the drawings.
[0032] The embodiment of the present application discloses a self-cleaning device for cutting navigation.
[0033] Referring to Figure 1, A self-cleaning device for cutting navigation, used for cleaning the wire mesh monitoring sensor of a hard and brittle material wire cutting machine. When the sensor moves to the end of the roller, the self-cleaning device cleans the surface of the sensor. The self-cleaning device includes a scraping device 3 for initially removing dirt and impurities on the surface of the sensor. The scraping device 3 includes a mounting plate 31 and a scraping strip 32. An installation groove is opened on the mounting plate 31, and the scraping strip 32 is slidably connected to the mounting plate 31 vertically in the installation groove. This sliding connection method facilitates the replacement of the scraping strip 32 and reduces the maintenance cost. The scraping strip 32 is made of elastic rubber material, which tightly connects the scraping strip 32 to the mounting plate 31 and reduces the damage of the scraping strip 32 to the sensor at the same time.
[0034] Refer to Figure 2 and Figure 3 , On the side of the mounting plate 31 away from the scraping strip 32, there is a rotating block 33. The rotating block 33 is rotatably connected to a moving block 34, and the axis of rotation is parallel to the extension direction of the scraping strip 32. This multi-directional rotational connection makes the scraping device 3 have higher degrees of freedom and flexibility, and can better adapt to the surfaces of sensors with various complex shapes. Specifically, a groove is opened on the side of the moving block 34 close to the rotating block 33. One end of the rotating block 33 extends into the groove and is rotatably connected to the moving block 34. There is a gap between the groove wall and the rotating block 33, leaving a rotating space for the rotating block 33 while restricting the rotation range of the rotating block 33. At the same time, there is also a baffle 35 on one side of the mounting plate 31. When the baffle 35 is in the initial position, the side of the baffle 35 away from the rotating block 33 is on the moving path of the sensor. When the sensor moves towards the baffle 35, the sensor abuts against the baffle 35. As the sensor continues to move, the baffle 35 and the rotating block 33 rotate together. The rotation of the baffle 35 drives the scraping strip 32 to rotate. At this time, the scraping strip 32 abuts against the sensor, and the initial scraping of the dirt on the surface of the sensor begins.
[0035] Refer to Figure 1 and Figure 3 , After the sensor completely passes through the baffle 35, during the return process, it abuts against the baffle 35 again. The rotation of the baffle 35 drives the scraping strip 32 to rotate, reducing the pollution of the sensor caused by the dirt and impurities on the scraping strip 32. At the same time, on the upper and lower ends of the side of the baffle 35 away from the rotating block 33, there are also rotatably connected guide wheels 351. The two guide wheels 351 are coaxially arranged, reducing the damage caused by the direct impact of the baffle 35 on the sensor.
[0036] Refer to Figure 4 , The moving block 34 is slidably connected to a cleaning head 2 for cleaning the sensor. A slide rail can be provided on the moving block 34, and a chute adapted to the slide rail is opened on the side plate of the cleaning head 2. The setting of the moving block 34 enables the entire scraping device 3 to be adjusted in position in the horizontal direction, so as to meet the cleaning requirements of sensors of different sizes.
[0037] Refer to Figure 1and Figure 4 On the side of the cleaning head 2 away from the scraping strip 32, a fixing plate 1 is provided. The cleaning head 2 is fixedly connected to the wire cutting machine by being fixed on the fixing plate 1. On the side of the cleaning head 2 away from the moving path of the sensor, an air inlet hole 22 and a water inlet hole 23 are provided. The air inlet hole 22 is communicated with the compressed air pipeline, and the water inlet hole 23 is communicated with the water inlet pipeline. On the side of the cleaning head 2 close to the moving path of the sensor, a plurality of cleaning holes 21 are provided. The air inlet hole 22 and the water inlet hole 23 are both communicated with the cleaning holes 21. Compressed air and water enter the cleaning head 2 respectively and are sprayed out from the cleaning holes 21, realizing the automatic cleaning of the sensor, effectively removing the dirt and impurities on the surface of the sensor, ensuring that the sensor can still work normally in a harsh environment, improving the anti-interference ability of the sensor, and further improving the stability and efficiency of the cutting process. In other embodiments, selecting either the air inlet hole 22 or the water inlet hole 23 can also achieve the above cleaning effect.
[0038] Refer to Figure 5 , specifically, the center line of the cleaning hole 21 extends along a direction inclined to the side surface of the cleaning head 2, so that the air flow and water flow sprayed out from the cleaning hole 21 are at an inclined angle, which can better cover and clean the surface of the sensor. Utilizing the gravity and impact force of water, the dirt and impurities on the sensor are effectively removed, the water stain residue is reduced, and the cleaning efficiency is improved. In practical applications, the inclination angle of the cleaning hole 21 can be adjusted according to the specific position and shape of the sensor. For example, the cleaning hole 21 can be provided below the cleaning head 2, and the cleaning hole 21 sprays and cleans obliquely upward towards the sensor, or the cleaning hole 21 can be provided above the cleaning head 2, and the cleaning hole 21 sprays and cleans obliquely downward towards the sensor to achieve the best cleaning effect.
[0039] Refer to Figure 3 , in order to better adapt to sensors with different shapes and positions, in this embodiment, the mounting plate 31 is also selected to be rotatably connected to the rotating block 33, and its rotation axis extends in the horizontal plane from the cleaning head 2 to the scraping strip 32 direction, which is the same as the moving direction of the sensor. This rotational connection enables the mounting plate 31 to rotate relative to the rotating block 33 by a certain angle, thereby adjusting the contact angle between the scraping strip 32 and the surface of the sensor to better adapt to sensors with different shapes and positions. Specifically, a rubber ring 36 is provided on the side of the rotating block 33 close to the scraping device 3. The rubber ring 36 abuts against the mounting plate 31. When the angle of the scraping device 3 is adjusted, the rubber ring 36 is compressed and deformed synchronously to make room for the angle adjustment of the scraping device 3.
[0040] Refer to Figure 2 and Figure 4, In addition, rotating rods 341 are provided above and below the rotating block 33. Through holes are formed in both rotating rods 341, and an elastic member 343 is connected between the two rotating rods 341. The moving block 34 is rotatably connected with a rotating wheel 342. The two ends of the elastic member 343 respectively pass through the through holes of the corresponding rotating rods 341 and abut against the mounting plate 31. Specifically, the elastic member 343 can be a spring or other elastic element. By rotating the rotating wheel 342, the elastic member 343 can be driven to move, thereby changing the pressure of the spring on the mounting plate 31, and thus controlling the rotation angle of the scraping strip 32. This adjustable design enables the scraping strip 32 to effectively scrape off dirt and impurities without causing excessive pressure damage to the sensor.
[0041] The implementation principle of the self-cleaning device for cutting navigation in the embodiment of the present application is as follows: The scraping strip 32 is used to initially scrape off the dirt and impurities on the surface of the sensor. Then, the air flow and water flow ejected through the cleaning holes 21 are used to further clean the sensor to ensure the cleanliness of the sensor. At the same time, the multi-directional adjustment and flexibility of the scraping device 3 enable it to adapt to the cleaning requirements of sensors with different shapes, sizes, and positions. Combining with the design of the efficient cleaning head 2 and the flexible adjustment of the scraping device 3 improves the cleaning effect on the sensor, enhances the working stability and reliability of the sensor in a harsh environment, improves the anti-interference ability of the sensor, and further improves the stability and efficiency of the cutting process. The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
