Description

Technical Field

[0001] The invention relates to the technical field of cleaning devices, in particular to a surface cleaning device for silicone rubber cables. Background Art

[0002] Cleaning devices usually refer to equipment or tools used to clean various objects or environments. Cleaning devices are involved in various fields. In the field of cables, cleaning devices are used to clean stains on the surface of cables to ensure the safe use of cables. During the production process, cables need to be covered with a protective cover on their surface. The material of the protective cover can be various rubber materials. These rubber materials are heated to a certain temperature to soften and plasticize them, and then the rubber materials are extruded and formed by an extruder and tightly wrapped on the outside of the cable. In order to prevent the silicone rubber cable from continuing to vulcanize due to its own residual heat, resulting in adhesion between the cable layers, talcum powder is needed to isolate it, and after production is completed, a cleaning device is needed to clean up the talcum powder to avoid affecting its use.

[0003] For example, Chinese patent CN110038833B discloses a novel online talcum powder cleaning device, which sets a talcum powder brush box, and four brush heads clean the surface of the cable. The rotation speed of the brush head is controlled by a rotation drive mechanism. The blowing device in the talcum powder brush box is directed to the brush head to blow off the talcum powder on the brush head, thereby achieving the function of cleaning the talcum powder on the cable surface.

[0004] However, the talcum powder in the above scheme is sprayed on the surface of the cable after washing with water. The adhesion of talcum powder is relatively strong, and the brush has a poor cleaning effect on the stone powder during cleaning. When cleaning some ribbon or flat cables, since these cables have grooves on their surfaces, there are dead corners during cleaning, resulting in worse cleaning effect. Summary of the invention

[0005] Based on this, it is necessary to provide a surface cleaning device for silicone rubber cables to address the problem that the current cleaning devices have poor cleaning effects.

[0006] The above purpose is achieved through the following technical solutions:

[0007] A surface cleaning device for a silicone rubber cable, comprising:

[0008] A frame, wherein a conveying assembly is disposed on the frame, and the conveying assembly is used to convey the silicone rubber cable;

[0009] A cleaning assembly, the cleaning assembly comprising a cleaning brush and a cleaning nozzle, the cleaning brush being rotatably disposed on the frame, the cleaning brush being located at the rear side of the cleaning nozzle in the conveying direction of the silicone rubber cable, the cleaning brush and the cleaning nozzle being used to clean the silicone rubber cable;

[0010] A controller, the controller is used to control the rotation angle of the cleaning brush and the cleaning nozzle;

[0011] An acquisition module, the acquisition module is used to acquire information parameters of the silicone rubber cable;

[0012] If the information parameter belongs to the first target type, the controller controls the cleaning component to clean the silicone rubber cable in a first cleaning mode;

[0013] If the information parameter belongs to the second target type, the controller controls the cleaning component to clean the silicone rubber cable in a second cleaning mode;

[0014] If the information parameter belongs to the third target type, the controller controls the cleaning component to clean the silicone rubber cable in a third cleaning mode;

[0015] Wherein, the information parameters at least include the shape of the silicone rubber cable and the surface state of the silicone rubber cable.

[0016] Further, if the information parameter belongs to the first target type, the controller controls the cleaning component to clean the silicone rubber cable in a first cleaning mode, including the following steps:

[0017] When the first target type is a round silicone rubber cable, the controller adjusts the rotating shaft of the cleaning brush and the round silicone rubber cable to be parallel to each other, and adjusts the angle between the cleaning nozzle and the round silicone rubber cable to be 45°.

[0018] Further, if the information parameter belongs to the second target type, the controller controls the cleaning component to clean the silicone rubber cable in a second cleaning mode, including the following steps:

[0019] When the second target type is a flat or ribbon-shaped silicone rubber cable, the surface state of the flat or ribbon-shaped silicone rubber cable is obtained. If the surface of the flat or ribbon-shaped silicone rubber cable has grooves, the controller adjusts the angle between the rotating shaft of the cleaning brush and the flat or ribbon-shaped silicone rubber cable to 45°, and adjusts the cleaning nozzle to spray perpendicularly to the flat or ribbon-shaped silicone rubber cable.

[0020] Further, if the information parameter belongs to the third target type, the controller controls the cleaning component to clean the silicone rubber cable in a third cleaning mode, including the following steps:

[0021] When the third target type is a flat or ribbon-shaped silicone rubber cable, the surface state of the silicone rubber cable is obtained, and if the surface of the silicone rubber cable is smooth, the controller adjusts the cleaning brush to be perpendicular to the flat or ribbon-shaped silicone rubber cable.

[0022] Furthermore, the rack is also provided with an identification module, which is used to identify identification information on the surface of the silicone rubber cable. If the identification information belongs to the first mark type, the first execution mode is executed; if the identification information belongs to the second mark type, the second execution mode is executed;

[0023] The identification information at least includes the tag type.

[0024] Further, if the identification information belongs to the first tag type, a first execution mode is executed, including the following steps:

[0025] When the first mark type is ink spraying, the mark spacing is obtained, and if the mark spacing is greater than a preset value, the area containing the identification information is blocked.

[0026] Further, if the identification information belongs to the first tag type, a first execution mode is executed, including the following steps:

[0027] When the first marking type is ink spraying, the marking distance is obtained. If the marking distance is less than a preset value, the same straight line area on the surface of the silicone rubber cable where the identification information is located is completely blocked.

[0028] Further, if the identification information belongs to the second tag type, the second execution mode is executed, including the following steps:

[0029] When the second mark type is laser engraving, the mark spacing is obtained. If the mark spacing is greater than a preset value, the pressure of the cleaning brush on the silicone rubber cable is increased and the air pressure of the cleaning nozzle is increased.

[0030] Further, if the identification information belongs to the second tag type, the second execution mode is executed, including the following steps:

[0031] When the second mark type is laser engraving, the mark spacing is obtained, and if the mark spacing is less than a preset value, the air pressure of the cleaning nozzle is increased.

[0032] Furthermore, the conveying assembly includes a plurality of conveying rollers, and the conveying rollers convey the silicone rubber cable.

[0033] The beneficial effects of the present invention are:

[0034] The present invention, through the setting of the cleaning component and the controller, enables the present invention to clean different types of silicone rubber cables, and can perform targeted cleaning according to the characteristics of different types of silicone rubber cables, especially for flat or ribbon-shaped silicone rubber cables with grooves, the dead corners of the grooves can be cleaned to avoid talcum powder residue in the grooves, thereby further improving the cleanliness of the surface of the silicone rubber cable.

[0035] The present invention also obtains identification information on the surface of the silicone rubber cable by setting an identification module, and selects different execution modes by judging the type of identification information and the marking spacing of the identification information, thereby avoiding the phenomenon that the identification information is worn and the identification is affected when the silicone rubber cable is cleaned.

Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.

[0050] Refer to the following Figure 1-Figure 7 The present invention will now describe a surface cleaning device for a silicone rubber cable.

[0051] A surface cleaning device for a silicone rubber cable is suitable for cleaning the surface of the silicone rubber cable, comprising a frame 100, a conveying assembly is arranged on the frame 100, the conveying assembly is used to convey the silicone rubber cable, the conveying assembly comprises a plurality of conveying rollers 110, the conveying rollers 110 clamp the silicone rubber cable, and the conveying rollers 110 rotate to realize the function of conveying the silicone rubber cable. A cleaning assembly 200 is arranged on the frame 100, the cleaning assembly 200 is used to clean the talcum powder on the surface of the silicone rubber cable, the cleaning assembly 200 comprises a cleaning brush 210 and a cleaning nozzle 220, the cleaning brush 210 is in direct contact with the surface of the silicone rubber cable, and the cleaning nozzle 220 sprays cleaning gas. Since the silicone rubber cable is produced by a drying tunnel or continuous vulcanization method, it cannot be guaranteed that the vulcanization degree of the silicone rubber reaches 100% in the drying tunnel or continuous vulcanization tube. After leaving the drying tunnel or vulcanization tube, the silicone rubber cable needs to be isolated with talcum powder to prevent the silicone rubber cable from continuing to vulcanize due to its own residual heat, which causes adhesion between cable layers. After cooling, the talcum powder needs to be cleaned. Since the shapes of silicone rubber cables are different, there are cleaning dead corners 312 during cleaning, which leads to incomplete cleaning of the talcum powder. The surface cleaning device for silicone rubber cables of the present invention also includes a controller 120, and the controller 120 is used to adjust the cleaning brush 210 and the cleaning nozzle 220 to switch the cleaning mode according to the different shapes of the silicone rubber.

[0052] Specifically in this embodiment, an acquisition module 130 is provided on the rack 100 , and the acquisition module 130 is used to acquire information parameters of the silicone rubber cable, and the information parameters include the shape of the silicone rubber cable and the surface state of the silicone rubber cable.

[0053] If the information parameter belongs to the first target type, the controller 120 controls the cleaning assembly 200 to clean the silicone rubber cable in the first cleaning mode;

[0054] Among them, the first target type is a circular silicone rubber cable 300, which is a regular shape. The first cleaning mode is that the controller 120 adjusts the rotating shaft 211 of the cleaning brush 210 to be parallel to the circular silicone rubber cable 300, and at the same time adjusts the angle between the cleaning nozzle 220 and the circular silicone rubber cable 300 to 45°, and the jet direction of the cleaning nozzle 220 is different from the conveying direction of the circular silicone rubber cable 300.

[0055] like Figure 2 As shown in ( Figure 2The arrows shown in the figure point to the conveying direction of the round silicone rubber cable 300 and the rotation direction of the cleaning brush 210). In the conveying direction of the round silicone rubber cable 300, the cleaning brush 210 is located at the rear side of the cleaning nozzle 220. The cleaning brush 210 first cleans the round silicone rubber cable 300 and then the cleaning nozzle 220 cleans the round silicone rubber cable 300. Since talcum powder is a powdery particle, it will generate dust after being attached to the surface of the round silicone rubber and being brushed by the cleaning brush 210. This may cause the surface of the round silicone rubber cable 300 cleaned by the cleaning brush 210 to re-attach talcum powder. The cleaning nozzle 220 is arranged behind the cleaning brush 210. The angle between the cleaning nozzle 220 and the round silicone rubber cable 300 is 45°, and the jet direction of the cleaning nozzle 220 is not on the same side as the conveying direction of the round silicone rubber cable 300. Then, the re-attached talcum powder can be cleaned off. The inclined setting of the cleaning nozzle 220 can prevent the dusty talcum powder from attaching to the surface of the round silicone rubber cable 300 again. Meanwhile, if the talcum powder is stubbornly attached to the circular silicone rubber surface, the stubborn talcum powder can be disturbed by the cleaning brush 210 to reduce its adhesion strength, and then it can be easily blown off when passing through the cleaning nozzle 220, resulting in a better cleaning effect.

[0056] It should be noted that the acquisition module 130 can identify the shape of the silicone rubber cable through image recognition or other methods to determine the target type, and transmit the acquired information to the controller 120, and the controller 120 selects a suitable cleaning mode according to the settings.

[0057] In other embodiments, the controller 120 of the present invention can also adjust the distance between the cleaning brush 210 and the cleaning nozzle 220 and the round silicone rubber cable 300 to accommodate round silicone rubber cables 300 of different diameters.

[0058] If the information parameter belongs to the second target type, the controller 120 controls the cleaning assembly 200 to clean the silicone rubber cable in the second cleaning mode.

[0059] The second target type is a flat or ribbon-shaped silicone rubber cable 310 , and some of the flat or ribbon-shaped silicone rubber cables 310 have grooves 311 on their surfaces, while others are smooth and do not have grooves 311 . If there is a groove 311, the second cleaning mode is used to clean the flat or ribbon silicone rubber cable 310. The second cleaning mode means that the controller 120 controls the shaft 211 of the cleaning brush 210 to form an angle of 45° with the flat or ribbon silicone rubber cable 310, and at the same time controls the cleaning nozzle 220 to spray perpendicularly to the flat or ribbon silicone rubber cable 310. The groove 311 extends along the length direction of the flat or ribbon silicone rubber cable 310. The setting of the groove 311 is usually used to enhance the flexibility and heat dissipation performance of the flat or ribbon silicone rubber cable 310. However, the existence of these grooves 311 is not conducive to the cleaning of the cleaning component 200. If the cleaning component 200 cannot completely clean the talcum powder in the groove 311, it will cause the heat dissipation effect of the groove 311 to decrease. Therefore, the second cleaning mode is used to thoroughly clean the groove 311.

[0060] It should be noted that if Figure 3 As shown ( Figure 3 The arrows shown in the figure point to the conveying direction of the flat or ribbon-shaped silicone rubber cable 310 and the rotation direction of the cleaning brush 210). When the angle between the rotating shaft 211 of the cleaning brush 210 and the flat or ribbon-shaped silicone rubber cable 310 is 45°, the cleaning brush 210 can clean the talcum powder in the groove 311 to the maximum extent. At the bottom edge of the groove 311, the talcum powder is easily accumulated there, and the rotating shaft 211 of the general cleaning brush 210 is parallel to the groove 311. Therefore, the cleaning brush 210 cannot clean the talcum powder in this part during cleaning, but it is easy to accumulate the talcum powder there. The talcum powder at the dead corner 312 is easily accumulated in the dead corner 312 because the rotating shaft 211 of the cleaning brush 210 is parallel to the groove 311, so when the cleaning brush 210 rotates, the bristles cannot enter the dead corner 312, and the talcum powder is easily accumulated in the dead corner 312). By changing the angle of the rotating shaft 211 of the cleaning brush 210, the cleaning brush 210 can have the ability to clean out the talcum powder at the dead corner, so that the talcum powder gradually moves along the cleaning direction of the cleaning brush 210, and then after the subsequent cleaning nozzle 220 cleans, the talcum powder at the dead corner can be cleaned more thoroughly, thereby preventing excessive accumulation of talcum powder and affecting the heat dissipation of the groove 311.

[0061] Specifically, through the first control experiment test, after experiments at various angles, it is concluded that the cleaning effect on the groove 311 is best when the angle is 45°. The specific experiment is as follows:

[0062] Under the same environment, and ensuring that the content of talcum powder in the groove 311 on the surface of the flat or ribbon silicone rubber cable 310 is the same, since it is difficult to detect the content of talcum powder, the talcum powder and fluorescent powder are mixed evenly and filled into the groove 311, and the cleanliness of the groove 311 is reflected by detecting the content of fluorescent powder remaining in the groove 311 after cleaning. More specifically, the content of fluorescent powder can be detected by UV light test, ensuring that other variables are the same, only changing the angle between the rotating shaft 211 of the cleaning brush 210 and the flat or ribbon silicone rubber cable 310, to conduct multiple experiments, it is detected that the less the content of fluorescent powder, the better the cleaning effect, and the more the content of fluorescent agent, the worse the cleaning effect. The experimental results are as follows Figure 5 shown.

[0063] The conclusion is that, in the process of the rotating shaft 211 of the cleaning brush 210 changing from being parallel to the flat or ribbon silicone rubber cable 310 (the angle when parallel here is 0°) to being perpendicular to the flat or ribbon silicone rubber cable 310, the mass of the fluorescent powder remaining in the groove 311 first decreases and then increases, which means that the cleaning effect of the cleaning brush 210 first gradually increases and then gradually decreases, and the turning point is at 45°. Therefore, an angle of 45° is selected, at which time the cleaning effect of the cleaning brush 210 is the best.

[0064] It should also be noted that the rotation direction of the cleaning brush 210 of the present invention is not on the same side as the conveying direction of the flat or ribbon-shaped silicone rubber cable 310, thereby increasing the force of the cleaning brush 210 on the talcum powder inside the groove 311, further improving the cleanliness of the inside of the groove 311.

[0065] When the surface of the flat or ribbon-shaped silicone rubber cable 310 does not have the groove 311 but is smooth, the third cleaning mode is used to clean the surface of the flat or ribbon-shaped silicone rubber cable 310. The third cleaning mode refers to the controller 120 adjusting the rotating shaft 211 of the cleaning brush 210 to be perpendicular to the flat or ribbon-shaped silicone rubber cable 310, and the controller 120 adjusting the cleaning nozzle 220 to spray vertically toward the flat or ribbon-shaped silicone rubber cable 310, such as Figure 4 As shown ( Figure 4The arrows shown in the figure point to the conveying direction of the flat or ribbon-shaped silicone rubber cable 310 and the rotation direction of the cleaning brush 210). Since the surface of the flat or ribbon-shaped silicone rubber cable 310 is composed of an arc surface and a plane surface, if the rotating shaft 211 of the cleaning brush 210 is parallel to the flat or ribbon-shaped silicone rubber cable 310, when the cleaning brush 210 is cleaning the junction of the plane and the arc surface, the pressure of the cleaning brush 210 on the arc surface is greater than the pressure on the plane surface, resulting in different cleaning degrees of the arc surface and the plane surface by the cleaning brush 210, that is, the cleanliness of the arc surface will be higher than the cleanliness of the plane surface. The rotating shaft 211 of the cleaning brush 210 is adjusted to be perpendicular to the flat or ribbon-shaped silicone rubber cable 310, so that the cleaning brush 210 cleans the plane and the arc surface separately, thereby making the plane and the arc surface of the flat or ribbon-shaped silicone rubber cable 310 have the same cleanliness.

[0066] Through the configuration of the cleaning component 200 and the controller 120 of the present invention, the present invention can clean different types of silicone rubber cables and can perform targeted cleaning according to the characteristics of different types of silicone rubber cables, thereby further improving the cleanliness of the silicone rubber cable surface.

[0067] In a further embodiment, an identification module 140 is further provided on the rack 100, and the identification module 140 is used to identify identification information on the surface of the silicone rubber cable. The surface of the silicone rubber cable is generally marked with identification information such as model, specification, production date, batch, manufacturer information or compliance mark. These identification information not only facilitates users, but also ensures safe, compliant and effective management. Through these identification information, the identification, installation and maintenance of the cable can be guaranteed, thereby improving the reliability and safety of the overall use process. However, during the cleaning process, these identification information may be affected. At the same time, the identification information of different marking types is also affected differently.

[0068] Generally, the marking type on the surface of the same silicone rubber cable is the same, and the marking type on the surface of the silicone rubber cable can be input into the identification module 140 in advance; it is also possible not to input the marking type in advance, but to let the identification module 140 identify it by itself. Ink spraying and laser engraving on the surface of the silicone rubber cable are different. The difference is that laser engraving will form a depression on the surface of the silicone rubber cable. Therefore, when the identification information is obtained, it is only necessary to determine whether there is a depression at the identification information. That is, a 3D scanning device (such as a laser scanner or a structured light 3D scanner) is added to the identification module 140, or structured light technology (such as projection stripes) is used to detect tiny bumps on the surface of the object, especially the area covered by impurities. Even if the impurities block the visual information of the surface, the depth information can still reflect the depression characteristics of the laser engraving. If the depression is not detected, it means that the marking type of the identification information is ink spraying.

[0069] It should be noted that the present invention is only applicable to silicone rubber cables of two marking types: ink spraying type and laser engraving type, and is not applicable to other marking types.

[0070] Specifically in this embodiment, if the identification information acquired by the identification module 140 is of the first marking type, the first execution mode is executed, wherein the first marking type is ink spraying, and the ink spraying can be performed on the surface of the silicone rubber cable in real time on a high-speed production line without significantly affecting the production speed. At the same time, the ink spraying can use high-contrast colors to make the identification information clearly visible on the surface of the silicone rubber cable. However, when spraying the ink, uneven spraying is prone to occur, which will cause uneven adhesion of the ink on the surface of the silicone rubber cable and is easily affected by external factors. Therefore, when dealing with identification information of the ink spraying type, the first execution mode is adopted. The first execution mode specifically blocks the identification information to prevent the identification information from being worn.

[0071] It should be noted that the identification module 140 in the present invention also has an image acquisition device and a speed sensor. The speed sensor is used to obtain the transmission speed of the silicone rubber cable. After the image acquisition device obtains the identification information, it leaves an image record and a time node. The image acquisition device transmits the various acquired data to the computing system, thereby calculating the length of the identification information and the spacing of the identification information.

[0072] For example, when cleaning the surface of a silicone rubber cable, the cleaning brush 210 or the cleaning nozzle 220 may wear out the identification information, resulting in unclear identification information. Therefore, after obtaining the type of identification information, the distribution spacing of the identification information is obtained through the identification module 140, that is, the marking spacing of the identification information (there are spacings between different identification information, for example, spacings are set between production dates and batches for easy identification, and the spacings between different identification information are different), so as to select different shielding methods according to the size of the spacings. If the marking spacing is greater than a preset value (the preset value is 1m, and the preset value can be adjusted in real time according to the overall length of the silicone rubber cable, and only 1m is taken as an example here), it is greater than the preset value, indicating that the spacing is large, and shielding the area where the identification information is located can be used to prevent the identification information from being worn.

[0073] Specifically, a robotic arm (not shown in the figure) for blocking the identification information can be set on the frame 100, and a tape roll (not shown in the figure) is set on the end of the robotic arm. When the identification module 140 obtains or manually inputs the marking type as an ink spray type, the robotic arm starts and moves to the position of the identification information to abut the tape roll on the identification information. At the same time, the time for which the tape roll abuts on the identification information is determined according to the length of the identification information detected by the identification module 140 to ensure that the identification information can be completely blocked.

[0074] For example, the time of obtaining the identification information through the identification module 140 is 2 seconds, and the conveying speed of the silicone rubber cable is 0.2 meters per second, then the length of the obtained identification information is 0.4 meters, and when the next identification information is obtained again after 6 seconds, the spacing between the identification information is 1.2 meters, so after the robot arm recognizes the identification information, the tape roll is abutted against the identification information area for 2 seconds, and then it is disengaged after 2 seconds, and it is abutted again after a time interval of 6 seconds, so that the tape on the tape roll is attached to the identification information to prevent the identification information from being worn. It should be noted that a cutter (not shown in the figure) is also provided on the robot arm, and the cutter cuts the tape every time the tape roll is disengaged. In the normal cleaning process of the silicone rubber cable, these identification information will not be worn. After cleaning, the blocked area will be opened and cleaned separately. Since the spacing of the identification information on the surface of the silicone rubber cable is long, the proportion of the identification information to the surface of the silicone rubber cable is small, and the cleaning area is large, only the identification information area is blocked, so that the cleaning area is large and the identification information is avoided. Wear and tear are achieved.

[0075] If the obtained marking spacing is smaller than the preset value, it means that the identification information on the silicone rubber cable occupies a large proportion of the surface of the silicone rubber cable, and the identification information on the silicone rubber cable is distributed along the length direction of the silicone rubber cable and on the same straight line, so the same straight line area where the identification information is located is completely blocked, that is, the robotic arm always keeps the tape roll in contact with the same straight line where the identification information is located, thereby completely blocking the same straight line area. It only needs to be blocked once to avoid a decrease in cleaning efficiency caused by frequent blocking of the identification information. After the silicone rubber cable is cleaned, the blocked area is opened for secondary cleaning. During cleaning, the cleaning force of the cleaning component 200 is reduced to avoid wear on the identification information. In this way, both cleaning efficiency and avoiding wear of the identification information can be achieved.

[0076] If the identification information acquired by the identification module 140 is of the second marking type, and the second marking type is laser engraving, laser engraving can prevent the identification information from being worn, but during laser engraving, the identification information forms depressions on the surface of the silicone rubber cable, and these depressions are prone to accumulate talcum powder, which blocks the identification information, especially some silicone rubber cables of similar colors, such as the identification information on the surface of a white silicone rubber cable. Since the color of talcum powder is close to white, the color difference between the two is very small, and when talcum powder accumulates in the depression of the identification information, it will affect the recognition of the identification information. For example, the original identification information contains the number 8, but white talcum powder accumulates in the middle or edge of the number 8, so it is mistakenly identified as a number such as 6, 9 or 0, and other numbers will also be mistakenly identified when talcum powder accumulates in other numbers, thereby affecting the subsequent use or classification of the silicone rubber cable.

[0077] Therefore, when targeting laser engraved type identification information, the second execution mode is executed. The second execution mode is to increase the cleaning force of the cleaning component 200. Since the depression of the identification information is much smaller than the groove 311 of the flat or ribbon silicone rubber cable 310, the cleaning difficulty is increased, so the cleaning force of the cleaning component 200 is increased to clean the depression of the identification information.

[0078] When the marking type is laser engraving, the identification module 140 obtains the marking spacing of the identification information. If the marking spacing of the identification information is greater than the preset value, the cleaning force of the cleaning brush 210 is increased and the air pressure of the cleaning nozzle 220 is increased, that is, the pressure of the cleaning brush 210 on the surface of the silicone rubber cable is increased. After increasing the pressure of the cleaning brush 210, due to the larger spacing of the identification information, the cleaning brush 210 can be prevented from brushing the talcum powder brushed out of the depression into the next depression again, and because the pressure of the cleaning brush 210 on the surface of the silicone rubber cable is increased, the talcum powder in the depression of the identification information is easier to detach, and the flushing force is greater after the air pressure of the cleaning nozzle 220 is increased, thereby avoiding the accumulation of talcum powder in the groove 311.

[0079] If the spacing of the identification information obtained by the identification module 140 is smaller than the preset value, the cleaning force on the depression is increased by increasing the air pressure of the cleaning nozzle 220. Since the spacing of the identification information is small, if the pressure of the cleaning brush 210 on the surface of the silicone rubber cable is increased, it is easy for the talcum powder cleaned by the cleaning brush 210 to enter the next depression. Therefore, the air pressure of the cleaning nozzle 220 can only be increased to make the cleaning nozzle 220 clean the depression more thoroughly to avoid the talcum powder affecting the identification information.

[0080] If the marking distance of the identification information is less than the preset value, increasing the pressure of the cleaning brush 210 on the surface of the silicone rubber cable will lead to a poor cleaning effect. This is because the identification information spacing is small, and the talcum powder brushed out by the cleaning brush 210 will be brushed into the depression of the next identification information by the cleaning brush 210. Since the pressure of the cleaning brush 210 on the surface of the silicone rubber cable increases, it is equivalent to the cleaning brush 210 tightly stuffing the talcum powder into the depression of the next identification information, which reduces the cleaning effect of the cleaning brush 210 and the cleaning nozzle 220. To prove the above conclusion, the following second control experiment is carried out:

[0081] The jet pressure of the cleaning nozzle 220 is controlled to be the same, and the identification information of the silicone rubber surface is controlled to be the same, and the content of talcum powder and fluorescent powder in the identification information is the same, etc., to ensure that other variables are the same. The only different variable is the pressure of the cleaning brush 210 on the silicone rubber cable surface. One group is normal pressure, and the other group is pressure greater than normal pressure. The results of the two groups of experimental data are shown as follows: Figure 6The conclusion is that, under the same cleaning force of the cleaning nozzle 220, the cleaning effect when the pressure is greater than the normal pressure is weaker than the cleaning effect when the normal pressure is used. Therefore, when the identification information mark spacing is less than the preset value, the pressure of the cleaning brush 210 on the silicone rubber surface is not increased, and only the air pressure of the cleaning nozzle 220 is increased.

[0082] The identification module 140 is set to obtain the identification information of the surface of the silicone rubber cable. By judging the type of the identification information and the marking spacing of the identification information, different execution modes are selected to avoid the phenomenon that the identification information is worn and the identification is affected when the silicone rubber cable is cleaned.
