DETAILED DESCRIPTION

[0039] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0041] In response to the technical problems recorded in the background technology, the applicant has found through research that the production demand for lightning arresters is large, and it is necessary to achieve rapid production of lightning arresters while ensuring the quality of lightning arresters to better meet the operational needs of lightning arresters. However, in the existing schemes for preparing zinc oxide resistors, when insulating the sides of zinc oxide resistors, the coating methods used will more or less involve human participation in the processing, and the degree of automation is low, which in turn reduces the production efficiency of zinc oxide resistors. In addition, when mass-producing zinc oxide resistors, due to the influence of uncontrollable factors such as human factors, there will be a common phenomenon of uneven coating of the side insulation layer and different local thicknesses, which affects the stability of mass-produced products and results in more side insulation flashovers in zinc oxide resistors during actual current impulse tests.

[0042] In response to at least one of the above problems, an embodiment of the present disclosure provides an automated spraying device, which utilizes a control module to control a discharging component to provide slurry to a spraying component, and controls the spraying component to spray the slurry to a target area of ​​a sample to be processed. No human operation is required, thereby improving the degree of automation, which in turn helps to improve the production efficiency of zinc oxide resistors.

[0043] The automated spraying device provided in the embodiments of the present disclosure is exemplarily described below in conjunction with the accompanying drawings.

[0044] Figure 1 A schematic diagram of the structure of an automated spraying device provided in an embodiment of the present disclosure, referring to Figure 1The automated spraying device includes: a discharging component 110, a spraying component 120 and a control module 130; the discharging component 110 and the spraying component 120 are electrically connected to the control module 130 respectively; the discharging component 110 is communicated with the spraying component 120; the control module 130 is used to control the discharging component 110 to provide slurry to the spraying component 120 (the slurry delivery direction is shown by the arrow direction), and control the spraying component 120 to spray the slurry to the target area of ​​the sample to be processed.

[0045] The target area of ​​the sample to be processed is the side area of ​​the sample to be processed (i.e., the zinc oxide resistor), and the material of the slurry is an insulating material used for application in the side area. By spraying the slurry on the side area of ​​the zinc oxide resistor, it is possible to avoid the problem of side flashover and damage when facing an actual high-amplitude lightning current impact, and in order to ensure the anti-flashover effect of the zinc oxide resistor, the slurry can be sprayed on the entire side area of ​​the zinc oxide resistor.

[0046] It is known that the prior art involves more or less human involvement in the process of coating the slurry on the side of the zinc oxide resistor, such as manual coating of the slurry, which makes the zinc oxide resistor prone to defects due to human factors. For example, the thickness of the film layer (also called the insulating layer) coated on the side is uneven, resulting in poor quality of the zinc oxide resistor, which is difficult to resist a series of damages caused by lightning strikes. At the same time, given the low degree of automation of this coating method, the production efficiency of the zinc oxide resistor needs to be improved.

[0047] Specifically, compared with the prior art, the embodiment of the present disclosure uses the control module 130 to control the discharging component 110 to provide slurry to the spraying component 120, so that the spraying component 120 can obtain the slurry in time without the need for manual addition of slurry, which helps the spraying component 120 to achieve continuous operation, that is, the control module 130 is used to control the spraying component 120 to automatically spray the slurry to the target area of ​​the sample to be processed without the need for human participation in the spraying, such as: the handheld spraying component sprays the slurry on the side area of ​​the zinc oxide resistor, thereby ensuring that the thickness of the insulating layer on the side of the zinc oxide resistor is uniform, reducing the occurrence of bubbles, sagging and other defects in the insulating layer, improving the preparation quality of the insulating layer, and then improving the safety and reliability of the zinc oxide resistor. At the same time, it also improves the overall degree of automation, saves labor costs, and is conducive to the rapid production of large quantities of zinc oxide resistors to meet the use requirements of power grid lines.

[0048] Exemplarily, the control module 130 may be a programmable logic controller (PLC), or may be other components with a master control function known to those skilled in the art, which is not limited herein.

[0049] Exemplarily, the insulating layer of the zinc oxide resistor can be any one of a high resistance layer, an insulating paint layer and a glass glaze layer, or a combination of any of the high resistance layer, the insulating paint layer and the glass glaze layer. The single thickness of the zinc oxide resistor can be 20mm to 40mm, which is not limited here.

[0050] The automatic spraying device provided by the embodiment of the present disclosure includes: a discharging component 110, a spraying component 120 and a control module 130; the discharging component 110 and the spraying component 120 are electrically connected to the control module 130 respectively; the discharging component 110 is connected to the spraying component 120; the control module 130 is used to control the discharging component 110 to provide slurry to the spraying component 120, and control the spraying component 120 to spray the slurry to the target area of ​​the sample to be processed. In this way, by using the control module 130 to control the discharging component 110 to provide slurry to the spraying component 120, and control the spraying component 120 to spray the slurry to the target area of ​​the sample to be processed, no manual operation is required, the degree of automation is improved, and then it helps to improve the production efficiency of zinc oxide resistors.

[0051] In some embodiments, Figure 2 A schematic diagram of the structure of another automatic spraying device provided in an embodiment of the present disclosure, Figure 3 This is a schematic diagram of the structure of another automatic spraying device provided in the embodiment of the present disclosure. Figure 2 and Figure 3 The discharge component 110 includes: a storage chamber 111, a stirring component 112 and a slurry pumping component 113; the stirring component 112 is arranged in the storage chamber 111; the stirring component 112 is electrically connected to the control module 130 through the slurry pumping component 113; the slurry pumping component 113 is connected to the spraying component 120; the storage chamber 111 is used to store the slurry to be sprayed; the slurry pumping component 113 is used to drive the stirring component 112 to stir the slurry and pump the slurry into the spraying component 120.

[0052] Exemplarily, the stirring component 112 may be a stirring structure such as a paddle-type agitator, a turbine-type agitator, etc. It should be noted that the slurry provided in the present disclosure is usually in a semi-liquid state. By arranging the stirring component 112 in the storage chamber 111, the slurry stored in the storage chamber 111 can be ground and stirred more evenly to prevent precipitation, agglomeration, etc., thereby ensuring that the slurry to be sprayed has good consistency and concentration, facilitating the smooth discharge of the slurry and forming a film layer with uniform thickness.

[0053] Specifically, the slurry pumping component 113 provides power to the stirring component 112, drives the stirring component 112 to rotate to stir the slurry, and pumps the stirred slurry in the storage chamber 111 into the spraying component 120, so that the spraying component 120 sprays the slurry. In this process, the speed of pumping the slurry into the spraying component 120, that is, the discharge speed, is controllable and adjusted by the control module according to the actual discharge demand.

[0054] Exemplarily, the slurry pumping component 113 may include a motor, a pump and a discharge pipe, and the motor and the pump are both controlled by the control module 130, wherein the motor is used to provide power, including but not limited to: driving the pump to work, and driving the stirring component 112 to work, etc. The pump is used to pump the slurry into the spray assembly 120, one end of the discharge pipe is connected to the storage chamber 111, and the other end is connected to the spray assembly 120, the slurry in the storage chamber 111 can be transported to the spray assembly 120 through the discharge pipe, so as to continuously provide slurry to the spray assembly 120.

[0055] In addition, by adjusting the power of the slurry pumping component 113, such as the power of the motor, the speed and direction of stirring of the stirring component 112 can be adjusted. For example, the power of the motor is determined by the current and voltage. By adjusting the current direction of the motor, the rotation direction of the motor can be changed, thereby changing the stirring direction of the stirring component 112. Alternatively, by adjusting the voltage and frequency of the motor, the speed of the motor can be changed, thereby changing the stirring speed of the stirring component 112. The power of the slurry pumping component 113 can be adaptively adjusted according to actual needs, which is not limited here.

[0056] In some embodiments, continue to refer to Figure 3 The spray assembly 120 includes: a spray gun 121 and a displacement frame 122; the spray gun 121 and the displacement frame 122 are both electrically connected to the control module 130; the spray gun 121 is fixed to the displacement frame 122; the displacement frame 122 is used to drive the spray gun 121 to move along the length direction of the displacement frame 122.

[0057] The spray gun 121 is at least connected to the storage chamber 111 to receive the slurry provided by the storage chamber 111 and spray it. Specifically, the spray gun 121 may include a nozzle for spraying the slurry, and the nozzle diameter is small, so that a highly atomized slurry can be produced based on the nozzle with a small diameter, and the spraying amount of the slurry can be more accurately controlled, the waste of the slurry can be reduced, and the production cost can be reduced. For example, the nozzle diameter can be between 0.5 mm and 1.8 mm, and can be specifically 1.5 mm. It is only necessary to ensure that the spray gun 121 can produce the above effect, and it is not limited here.

[0058] It should be noted that, in three-dimensional space, three directions that are perpendicular to each other, such as the X-axis direction, the Y-axis direction and the Z-axis direction, can be used to define a spatial rectangular coordinate system. For example, the X-axis and the Y-axis can both be in a horizontal plane, and the Z-axis can be a vertical direction perpendicular to the horizontal plane. On this basis, the length direction of the displacement frame 122 represents the Z-axis direction (that is, the longitudinal direction), and the displacement frame 122 can be extended and retracted back and forth in this direction.

[0059] Specifically, the displacement rack 122 is controlled by the control module 130 to extend and retract in its length direction, and can drive the spray gun 121 to move in this direction, thereby adjusting the position of the spray gun 121, making it convenient for the spray gun 121 to move to a suitable position close to the target area of ​​the sample to be processed, such as: toward the side of the side area of ​​the zinc oxide resistor. In this way, the spray gun 121 can smoothly spray the slurry to the target area of ​​the sample to be processed, reducing the spraying error.

[0060] In addition, the speed of extension and retraction of the displacement frame 122 is adjustable, thereby realizing the adjustment of the moving speed of the spray gun 121. For example, the displacement frame 122 can be set to drive the spray gun 121 to move at a uniform speed along the length direction of the displacement frame 122. In this way, when multiple zinc oxide resistors are stacked, the spray gun 121 can spray the side area of ​​each zinc oxide resistor in turn to ensure that the side area of ​​each zinc oxide resistor is evenly sprayed with slurry. The size of its uniform speed movement can be set according to actual spraying requirements and is not limited here.

[0061] Exemplarily, the displacement frame 122 may include rod segments, guide structures, motors, etc., wherein multiple rod segments are sequentially socketed, and the motor can drive the rod segments to extend and retract along a straight path specified by the guide structure. In other embodiments, the displacement frame 122 can also achieve the above functions through other structures, which are not limited here.

[0062] In some embodiments, continue to refer to Figure 3 There are multiple spray guns 121, and the displacement frame 122 and the spray guns 121 are fixed one to one.

[0063] Specifically, by setting the number of spray guns 121 to be multiple, and fixing the displacement rack 122 and the spray gun 121 one-to-one, it is suitable for the scenario where the number of samples to be processed is also multiple. In this scenario, each spray gun 121 can correspond to at least one sample to be processed, and the spray gun 121 can perform one-to-one targeted spraying on the sample to be processed close to it, which significantly improves the production efficiency and facilitates the mass production of zinc oxide resistors.

[0064] In some embodiments, continue to refer to Figure 3The spray assembly 120 also includes: a gas pumping component 123; the gas pumping component 123 is electrically connected to the control module 130; the spray gun 121 is connected to the gas pumping component 123; the gas pumping component 123 is used to ventilate the spray gun 121 to drive the spray gun 121 to spray the slurry.

[0065] Specifically, the gas pumping component 123 is controlled by the control module 130 to pass a certain amount of gas into the spray gun 121, providing a preset air pressure for the spray gun to drive the spray gun 121 to spray the slurry. It can be understood that by controlling the amount of gas passed into the spray gun 121, the speed at which the spray gun 121 sprays the slurry, the spraying state of the slurry, and the amount of slurry discharged, etc., can be further adjusted to achieve the spraying effect of controlling the side area of ​​the zinc oxide resistor.

[0066] Based on this, the gas pumping component 123 can provide a larger air pressure, for example: the air pressure can be 0.2MPa~1MPa, specifically can be set to 0.7MPa, so that the sprayed slurry is highly atomized, and the film layer formed is more uniform. At the same time, the slurry discharge volume is in a suitable range, such as 100L / min~300mL / min, which can be adjusted according to actual spraying requirements, and is not limited here.

[0067] Exemplarily, the gas pumping component 123 may include an air pump and an air pipe, one end of the air pipe is connected to the air pump, and the other end is connected to the spray gun 121. In this way, the air pump can ventilate the spray gun 121 through the air pipe to provide air pressure for it.

[0068] In some embodiments, Figure 4 A schematic diagram of the structure of a spray assembly provided in an embodiment of the present disclosure, combined with Figure 3 and Figure 4 The spraying assembly 120 also includes: a workbench 124, a first rotating component 125 and a plurality of second rotating components 126; the first rotating component 125 is located on the workbench 124; the plurality of second rotating components 126 are located on the first rotating component 125; the first rotating component 125 and the second rotating component 126 are both electrically connected to the control module 130; the second rotating component 126 is used to carry the sample to be processed and to drive the sample to be processed to rotate in a controlled manner; the first rotating component 125 is used to drive the second rotating component 126 to rotate to one side of the spray gun in a controlled manner.

[0069] The control module 130 can independently control the first rotating component 125 and the second rotating component 126. Specifically, the first rotating component 125 is controlled by the control module 130 to rotate on the workbench 124, thereby driving the second rotating component 126 to rotate accordingly, and the second rotating component 126 is controlled by the control module 130 to rotate on the first rotating component 125, thereby driving the sample to be processed to rotate accordingly.

[0070] In particular, when the first rotating component 125 drives the second rotating component 126 to rotate to one side of the spray gun, the first rotating component 125 is controlled to stop rotating. At this time, the nozzle of the spray gun is facing the side area of ​​the zinc oxide resistor carried by the second rotating component 126. The second rotating component 126 can be controlled by the control module 130 to rotate on the first rotating component 125, so that the spray gun 121 can evenly spray the slurry on the entire side area of ​​the zinc oxide resistor to ensure the anti-flashover effect of the zinc oxide resistor. At the same time, accurate spraying of each zinc oxide resistor is achieved to reduce the waste of slurry.

[0071] For example, the automatic spraying device may further include a first rotating shaft 1251 adapted to the first rotating component 125, and a second rotating shaft (not shown) adapted to the second rotating component 126, and the second rotating component 126 corresponds to the second rotating shaft one by one, and the control module 130 drives the first rotating component 125 to rotate by driving the first rotating shaft 1251 to rotate, and drives the second rotating component 126 to rotate by driving the second rotating shaft to rotate. In addition, the shapes of the first rotating component 125 and the second rotating component 126 may be Figure 3 The shapes shown are circular. In other embodiments, the shapes of the first rotating component 125 and the second rotating component 126 may also be square, elliptical, etc., which are not limited here.

[0072] Preferably, the first rotating component 125 and the second rotating component 126 are controlled to rotate at a uniform speed, so that the slurry can be stably and evenly sprayed to the side area of ​​the zinc oxide resistor. The speed of the first rotating component 125 can be 0.9r / min, and the speed of the second rotating component 126 can be 1r / min. The control module 130 can adjust its speed according to the actual spraying requirements, which is not limited here.

[0073] In some embodiments, continue to refer to Figure 3 The automated spraying device further includes a recovery component 140 and a detection component 150; the spraying component 120 and the discharging component 110 are respectively connected to the recovery component 140; the detection component 150 is electrically connected to the control module 130; the recovery component 140 is used to introduce the remaining slurry in the spraying component 120 into the discharging component 110; the detection component 150 is at least used to detect the weight of the sample to be processed before and after spraying, and the concentration of the slurry in the environment.

[0074] Specifically, the slurry in the spray assembly 120 that is not sprayed out by the spray gun can be introduced into the discharge assembly 110 through the recovery assembly 140, so as to realize the recycling of the slurry and reduce the waste of the slurry. For example, the storage chamber in the discharge assembly 110 can be provided with a return port, and the recovery assembly 140 can include a return pipe, one end of which is connected to the spray gun, and the other end is connected to the return port of the storage chamber, so that the remaining slurry in the spray gun re-enters the storage chamber through the return pipe and the return port for subsequent spraying.

[0075] It is not difficult to understand that the detection component 150 can be arranged on the second rotating part to detect the weight of the zinc oxide resistor before and after spraying, and transmit the detected weight data to the control module 130. The control module 130 calculates the weight change of the sample to be processed before and after spraying, compares it with the weight change threshold, and determines whether the weight of the zinc oxide resistor after spraying reaches the specified weight requirement. Exemplarily, the detection component 150 may include a weight sensor for real-time detection of the weight of the zinc oxide resistor.

[0076] In addition, when the spray gun sprays the slurry, the slurry may be in a highly atomized state, and more slurry particles may float in the air. In this regard, the detection component 150 may detect the concentration of the slurry particles floating in the environment, and transmit the detected concentration data to the control module 130, so that the control module 130 performs corresponding actions according to the current concentration, such as controlling the purification component described later to adsorb the slurry particles. Exemplarily, the detection component 150 may include a concentration detector for real-time detection of the concentration of slurry particles in the area where the automated spraying device is located.

[0077] In some embodiments, continue to refer to Figure 3 The automatic spraying device further includes a purification component 160; the purification component 160 is electrically connected to the detection component 150; the purification component 160 is used to absorb the slurry in the environment.

[0078] Specifically, after the control module 130 receives the concentration data for the slurry particles sent by the detection component 150, if it is determined that the concentration of the slurry particles is large, the control module 130 can control the purification component 160 to start up to strongly adsorb the slurry particles in the environment, reduce the residual slurry particles in the air, and prevent the slurry particles floating in the environment from falling on the side area of ​​the zinc oxide resistor after spraying, affecting the uniformity and smoothness of its film layer, improving the quality of the zinc oxide resistor, and at the same time, improving the air quality of the current (working) environment to meet environmental protection requirements.

[0079] It should be noted that the power of the purification component 160 and the flow rate of the spray gun can be adjusted to control the concentration of the slurry particles in the working environment. For example, if the power of the purification component 160 and the flow rate of the spray gun are both reduced, the concentration of the slurry particles in the working environment will also become smaller. The specific values ​​of the power of the purification component 160 and the flow rate of the spray gun can be set according to actual purification needs and are not limited here.

[0080] Exemplarily, the purification component 160 can also be connected to the storage chamber in the discharge component to guide the slurry adsorbed thereon into the storage chamber to achieve the recovery of the slurry. In addition, the purification component 160 can include a bag dust removal device for adsorbing slurry particles during operation, and the specific type of the purification component 160 is not limited here.

[0081] In some embodiments, continue to refer to Figure 3 The automatic spraying device also includes a prompt module 170; the prompt module 170 is electrically connected to the detection component 150; the prompt module 170 is used to issue weight prompt information and / or concentration prompt information.

[0082] The weight prompt information is used to indicate the weight of the zinc oxide resistor after spraying, and the concentration prompt information is used to indicate the concentration of the slurry (particles) in the environment.

[0083] Specifically, when the control module 130 determines that the weight of the zinc oxide resistor after spraying does not meet the specified weight requirement, the prompt module 170 can be controlled to send out a weight prompt message, for example: the prompt module 170 can be an indicator light, which can emit a red light to prompt that the weight of the zinc oxide resistor after spraying does not meet the specified weight requirement, or the prompt module 170 can be a screen, which can display the above weight prompt message in the form of text, or the prompt module 170 can also be a speaker to send out the above weight prompt message in the form of voice broadcast. In this way, the effect of spraying the side area of ​​the zinc oxide resistor can be monitored.

[0084] In addition, if the control module 130 determines that the concentration of slurry particles in the environment is large, such as when the concentration of slurry particles exceeds the concentration threshold, the prompt module 170 can be controlled to issue a concentration prompt message, for example, the prompt module 170 can be an indicator light, which can emit a green light to indicate that the concentration of slurry particles exceeds the concentration threshold. In this way, the concentration of slurry particles in the environment can be monitored.

[0085] In some embodiments, the automated spraying device further includes a line collection box (not shown); the line collection box is used to store electrical connection lines.
