Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wire cutting, in particular to an oil-gas lubrication control method, system, medium, control device and wire cutting machine. BACKGROUND

[0002] Wire cutting is a processing method that cuts workpieces (such as photovoltaic silicon rods, semiconductors, silicon carbide, sapphire, magnetic materials, etc.) by high-speed reciprocating movement of a cutting wire and relative movement of the cutting wire and the workpieces.

[0003] The main roller assembly is one of the key components for completing cutting. The main roller is supported at both ends by a bearing box, and the cutting wire is wound around the main roller to form a wire net for cutting the workpieces. At present, most bearing boxes are still manually injected with lubricating grease (oil) for lubrication, which has the problem of high labor cost. Secondly, due to the characteristics of high speed, high torque and high response of the wire cutting machine during cutting, the use of high-speed bearing grease for lubrication will cause the lubricant to scatter and not easily adhere to the rolling surface. In addition, during manual oil injection, the lubricating grease is easily contaminated, affecting the lubrication effect, and even causing damage to the bearing box.

[0004] Correspondingly, there is a need in the art for a new technical solution to solve the above problems. SUMMARY

DETAILED DESCRIPTION

[0067] The preferred embodiments of the present application will be described in reference to the drawings. Those skilled in the art will understand that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application. For example, although the detailed steps of the method of the present application are described in detail below, those skilled in the art can combine, split and change the order of the steps described below without departing from the basic principles of the present application. The technical solutions modified in this way do not change the basic concept of the present application, and therefore fall within the protection scope of the present application.

[0068] It should be noted that in the description of the present application, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0069] In addition, it should also be noted that in the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through an intermediate medium, or internal communication of two elements. Those skilled in the art can understand the specific meaning of the above terms in the present application according to the specific circumstances.

[0070] Firstly, the oil-air lubrication system of the present application is introduced. Figure 1 The oil-air lubrication system of the present application is introduced.

[0071] As Figure 1As shown, to address the problems of low automation, difficult lubricant adhesion, high cost, and low cleanliness in existing bearing housing lubrication methods, the oil-air lubrication system of this application includes an oil circuit assembly 1, an air circuit assembly 2, an oil separator 3, and a controller 4. The oil circuit assembly 1 provides lubricating oil, and the air circuit provides compressed gas. Both the oil circuit assembly 1 and the air circuit assembly 2 are connected to the oil separator 3, which is connected to the component 5 to be lubricated. The oil separator 3 is used to mix the lubricating oil and compressed gas into an oil-air mixture. The controller 4 is connected to the oil circuit assembly 1 and the air circuit assembly 2 and is used to control the start and stop of the oil circuit assembly 1 and the air circuit assembly 2.

[0072] In application, the controller 4 controls the oil circuit assembly 1 and the air circuit assembly 2 to supply lubricating oil and compressed air to the oil separator 3 respectively based on the received lubrication command. The lubricating oil and compressed air are mixed in the oil separator 3 to become oil-air mixture. The oil separator 3 is used to discharge the mixed oil-air mixture intermittently at the optimal cycle. The discharged oil forms a continuous liquid flow before reaching the part to be lubricated 5 and is sent into the part to be lubricated 5 along with the air for lubrication.

[0073] The aforementioned oil-air lubrication system can automatically supply oil and air to the parts 5 to be lubricated, improving the degree of automation in lubrication. Furthermore, under the action of compressed air, the lubricating oil flows continuously in a spiral motion along the inner wall of the oil-air pipeline, forming a continuous oil film that adheres to the parts 5 to be lubricated, thus improving the adhesion effect. Moreover, the automatic oil-air injection control method reduces labor costs and minimizes lubrication contamination.

[0074] The following reference Figure 1 This application describes a preferred embodiment of the oil-gas lubrication system.

[0075] like Figure 1 As shown, in a preferred embodiment, the oil-air lubrication system includes an oil circuit assembly 1, an air circuit assembly 2, an oil distribution block 3, a controller 4, and an interactive screen 6.

[0076] Specifically, the oil circuit assembly 1 includes an oil pump 11, a power supply valve 12, a filter 13, and an oil pressure sensor 14. The oil pump 11 supplies lubricating oil for oil-air lubrication. The power supply valve 12 is connected to the outlet of the oil pump 11 and is used to control the on / off state of the oil circuit. The inlet of the filter 13 is connected to the outlet of the power supply valve 12, and the outlet of the filter 13 is connected to the oil distributor 3. The filter 13 cleans and filters the lubricating oil. The oil pressure sensor 14 is used to detect the oil pressure of the oil circuit assembly 1.

[0077] The air path assembly 2 comprises an air pump 21, a gas supply valve 22 and an air pressure detection sensor 23. The air pump 21 is used to provide clean compressed air. The inlet of the gas supply valve 22 is in communication with the outlet of the air pump 21, the outlet of the gas supply valve 22 is in communication with the oil distribution block 3, and the gas supply valve 22 is used to control the opening and closing of the air path. The air pressure detection sensor 23 is arranged between the air pump 21 and the gas supply valve 22, and the air pressure detection sensor 23 is used to detect the air pressure of the air path assembly 2.

[0078] The oil distribution block 3 preferably adopts a quantitative piston type dispenser. The main function of the oil distribution block 3 is to mix lubricating oil and compressed air to form oil-air mixture of a certain concentration, and then deliver the mixed oil-air mixture to specific parts to be lubricated 5. At the same time, the oil distribution block 3 can set a specific opening for each oil distribution path to provide an appropriate amount of mixed oil-air mixture.

[0079] The interactive screen 6 is connected with the controller 4, and the interactive screen 6 is used to receive control parameters and display process parameters. The interactive screen 6 is a touch screen, and through the touch screen, the user can directly set and read the required parameters of the oil-air lubrication.

[0080] The controller 4 preferably adopts a programmable logic controller 4 (PLC). The controller 4 is connected with the oil supply valve 12, the gas supply valve 22, the oil pressure detection sensor 14, the air pressure detection sensor 23 and the interactive screen 6, so as to receive data or instructions from the sensors and the interactive screen 6, and control the opening and closing of the valves.

[0081] In this application, the parts to be lubricated 5 are bearing boxes, and each main roller of the wire cutting machine is connected with one bearing box at each end, i.e. a first bearing box and a second bearing box. The outlets of the oil distribution block 3 are in communication with the first bearing box and the second bearing box to supply the mixed oil-air mixture to the two bearing boxes.

[0082] In this system, the oil supply pressure and the gas supply pressure can be monitored in real time through the controller 4 and the interactive screen 6. The mixed oil-air mixture is discharged intermittently at the best cycle to ensure the safe and stable operation of the system and the bearing boxes. Once an abnormality occurs in the operation of the entire system, it can be detected immediately and an alarm can be sent to prompt the operator to handle it. The compressed air can keep the lubricated parts at a certain positive pressure, keep them clean, and reduce the temperature of the bearing boxes. By arranging the oil pressure detection sensor 14, the oil pressure can be detected in real time to improve the lubrication control accuracy of the system. By arranging the air pressure detection sensor 23, the air pressure can be detected in real time to improve the lubrication control accuracy of the system. By arranging the interactive screen 6, the control difficulty can be reduced.

[0083] It should be noted that the above preferred embodiments are only used to illustrate the principles of the present application, and are not intended to limit the protection scope of the present application. Those skilled in the art can adjust the above arrangement without departing from the principles of the present application, so that the present application can be applied to more specific application scenarios.

[0084] For example, in an alternative embodiment, the specific arrangement of the oil circuit assembly 1 and the gas circuit assembly 2 is not unique, and those skilled in the art can adjust it according to specific needs. For example, the filter 13, the oil pressure detection sensor 14, etc. in the oil circuit assembly 1 can be omitted. For another example, the gas pressure detection sensor 23 in the gas circuit assembly 2 can be omitted, etc.

[0085] For another example, in another alternative embodiment, although the above embodiment is introduced in combination with the arrangement of the interactive screen 6, the arrangement of the interactive screen 6 is not necessary, and those skilled in the art can choose whether to arrange the interactive screen 6 according to specific needs.

[0086] For another example, in another alternative embodiment, although the above-mentioned lubricated component 5 is a bearing box, this is only exemplary, and those skilled in the art can also apply the system to other components of the wire cutting machine that need to be lubricated. For example, the main roller motor, etc.

[0087] Of course, the above-mentioned alternative embodiments can also be cross-used between each other and between the alternative embodiments and the preferred embodiments, so as to combine new embodiments to be applied to more specific application scenarios.

[0088] The following refers to Figure 2 The oil-gas lubrication control method of the present application is introduced.

[0089] As Figure 2 shown, corresponding to the above-mentioned oil-gas lubrication system, the oil-gas lubrication control method of the present application comprises:

[0090] S101, detecting whether the oil-gas lubrication interval time length of the lubricated component reaches the preset interval time length. For example, during the operation of the main roller of the wire cutting machine, the controller detects the oil-gas lubrication interval time length of the bearing box and judges whether it reaches the preset interval time length. The preset interval time length is preset at the factory or set by the operator on site.

[0091] S103, when it is detected that the oil-gas lubrication interval time length reaches the preset interval time length, controlling the oil-gas lubrication system to inject oil-gas to the lubricated component. For example, when it is detected that the oil-gas lubrication interval time length reaches the preset interval time length, the controller controls the power supply valve and the gas supply valve to open, the oil pump supplies oil to the oil distribution block, the gas pump supplies gas to the oil distribution block, and the lubricating oil and compressed air are mixed in the oil distribution block to supply the first bearing box and the second bearing box, and lubricate them.

[0092] S105, detecting whether the oil gas lubrication duration reaches a first preset duration. For example, the oil gas lubrication duration is the duration of injecting oil gas into the bearing box. After starting to inject oil gas, the controller detects the oil gas lubrication duration and judges whether the first preset duration is reached. The first preset duration is preset at the factory or set by the operator on site.

[0093] S107, when detecting that the oil gas lubrication duration reaches the first preset duration, controlling the oil gas lubrication system to stop injecting oil gas into the component to be lubricated. For example, when detecting that the oil gas lubrication duration reaches the first preset duration, the controller controls the power supply valve and the gas supply valve to be closed, at which time the oil pump stops supplying oil to the oil distribution block, and the gas pump simultaneously stops supplying gas to the oil distribution block.

[0094] The application sets an oil gas lubrication system. When the lubrication interval duration of the component to be lubricated reaches the preset interval duration, the oil gas lubrication system is controlled to inject oil gas into the component to be lubricated. Then, when the injection duration of oil gas reaches the first preset duration, the injection of oil gas is stopped. This is repeated to achieve intermittent automatic supply of oil gas to the component to be lubricated, improve the degree of automation of lubrication, and under the flow action of compressed air, the lubricating oil continuously spirally flows along the inner wall of the oil gas pipeline and forms a continuous oil film attached to the component to be lubricated, improving the attachment effect. In addition, due to the automatic injection of oil gas, labor costs can be reduced, and lubrication pollution is less likely to occur. Through repeated testing, monitoring, analysis and comparison by the applicant, it is found that during the oil gas lubrication process, the more lubricating oil is not necessarily better. Too much lubricating oil can cause the bearing box to heat up seriously. Therefore, the injection time of oil gas needs to be set. After the injection time of oil gas reaches, the injection of oil gas is stopped to form intermittent lubrication to achieve the best lubrication effect.

[0095] The preferred embodiments of the control method of the application are described below.

[0096] In a preferred embodiment, the first preset duration is any value in 2s-10s, and the preset interval duration is any value in 200s-500s. Preferably, the first preset duration is 5s, and the preset interval duration is 360s. In other words, after controlling the oil gas lubrication system to continuously supply oil gas to the first bearing box and the second bearing box for 5s, the oil gas lubrication system is controlled to stop supplying oil to the first bearing box and the second bearing box for 360s, so that the previously injected oil gas can better adhere to the surface of the bearing box, improving the lubrication capacity and the reliability of the equipment.

[0097] Of course, the specific values of the first preset duration and the preset interval duration are not fixed and can be adjusted by those skilled in the art based on specific application scenarios.

[0098] In a preferred embodiment, before the oil gas lubrication system injects oil gas into the component to be lubricated, the oil gas lubrication control method further comprises: detecting whether the startup state of the oil gas lubrication system is the first startup after power-on; if it is detected that the startup state is the first startup after power-on, controlling the oil gas lubrication system to perform a pre-lubrication operation, and after the pre-lubrication operation is completed, performing the step of "controlling the oil gas lubrication system to inject oil gas into the component to be lubricated"; if it is detected that the startup state is not the first startup after power-on, performing the step of "controlling the oil gas lubrication system to inject oil gas into the component to be lubricated". Specifically, the step of "controlling the oil gas lubrication system to perform a pre-lubrication operation" further comprises: controlling the oil gas lubrication system to inject oil gas into the component to be lubricated for a second preset duration. The second preset duration is any value in the range of 100s-300s. Preferably, the second preset duration is 180s.

[0099] For example, after the online cutting machine is stopped for a period of time and restarted, the pipeline of the oil gas lubrication system is full of air. At this time, when the oil gas lubrication system is started again, the oil gas lubrication system is controlled to perform a pre-lubrication operation for 180s, that is, the power supply valve and the gas supply valve are controlled to be opened and maintained for 180s, and the oil gas is injected into the lubrication pipeline to expel the air in the oil gas lubrication pipeline, so that the lubricating oil gas fills the pipeline. At the same time, it also plays a role in cleaning the pipeline and the component to be lubricated. Then, the above-mentioned intermittent lubrication operation is started.

[0100] By controlling the oil gas lubrication system to perform a pre-lubrication operation at the first startup after power-on, the air in the oil gas lubrication pipeline can be expelled, and the lubricating oil gas fills the pipeline. At the same time, it also plays a role in cleaning the pipeline and the component to be lubricated, thereby improving the lubrication effect.

[0101] In a preferred embodiment, the control method further comprises: when the oil gas lubrication system is started for the first time after power-on, waiting for a third preset duration before controlling the oil gas lubrication system to perform a pre-lubrication operation. The third preset duration is any value in the range of 20s-60s. Preferably, the third preset duration is 40s.

[0102] For example, when the oil gas lubrication system is started for the first time, all devices in the system are in a preheating stage and are not yet stable in operation. At this time, 40s is waited for to allow the devices to start running, and then the pre-lubrication operation is started, so as to improve the effect of the pre-lubrication operation.

[0103] Of course, the specific values of the second preset duration and the third preset duration are only exemplary, and a person skilled in the art can adjust them based on specific application scenarios.

[0104] In a preferred embodiment, before the step of controlling the oil-gas lubrication system to inject oil-gas to the component to be lubricated, the control method further comprises: detecting whether the oil-gas starting parameter of the oil-gas lubrication system meets the starting condition; when it is detected that the oil-gas starting parameter meets the starting condition, performing the step of controlling the oil-gas lubrication system to inject oil-gas to the component to be lubricated; when it is detected that the oil-gas starting parameter does not meet the starting condition, controlling the oil-gas lubrication system to output an alarm information. Specifically, the oil-gas starting parameter comprises the oil pressure of the oil circuit assembly, the air pressure of the air circuit assembly, and the lubricating oil level of the oil circuit assembly, and the starting condition comprises the following conditions:

[0105] (1) judging whether the oil pressure of the oil circuit assembly is in a preset oil pressure threshold interval to obtain a first judgment result;

[0106] (2) judging whether the air pressure of the air circuit assembly is in a preset air pressure threshold interval to obtain a second judgment result;

[0107] (3) judging whether the lubricating oil level of the oil circuit assembly is greater than a liquid level threshold to obtain a third judgment result;

[0108] According to the first judgment result, the second judgment result, and the third judgment result, it is detected whether the oil-gas starting parameter meets the starting condition.

[0109] In the preferred technical solution of the above oil-gas lubrication control method, when the first judgment result indicates that the oil pressure is in the preset oil pressure threshold interval, the second judgment result indicates that the air pressure is in the preset air pressure threshold interval, and the third judgment result indicates that the lubricating oil level is greater than the liquid level threshold, it is determined that the oil-gas starting parameter meets the starting condition; otherwise, it is determined that the oil-gas starting parameter does not meet the starting condition.

[0110] For example, the preset oil pressure threshold interval can be any value in 1.0-2.0 MPa, the preset air pressure threshold interval can be any value in 0.2-0.6 MPa, and the liquid level threshold of the lubricating oil can be a height value corresponding to 0.1-0.5 L. When the oil pressure is not in the preset oil pressure threshold interval, the supply of lubricating oil is unstable, which is not conducive to providing stable lubricating oil. Similarly, when the air pressure is not in the preset air pressure threshold interval, the supply of compressed air is unstable, which is not conducive to providing stable compressed air. When the lubricating oil level is too low, the amount of lubricating oil is reduced and needs to be supplemented, otherwise the oil pump may be idling. If the above conditions are met, i.e., at least one of the above three conditions is not met, it is determined that the oil-gas starting parameter does not meet the starting condition, and the oil-gas lubrication system outputs an alarm information, such as an acoustic / visual / text alarm information, to prompt the user that the system has a fault and needs to be checked in time. If the above starting conditions are all met, it is determined that the oil-gas starting parameter meets the starting condition, and the oil-gas lubrication system injects oil-gas to the component to be lubricated.

[0111] By controlling the oil gas lubrication system to inject oil gas to the component to be lubricated when the oil gas starting parameter meets the starting condition, the starting stability of the oil gas lubrication system can be improved. When the oil gas starting parameter does not meet the starting condition, the oil gas lubrication system outputs an alarm information, which can avoid the failure of the oil gas lubrication system and improve the lubrication effect.

[0112] In another embodiment, the oil gas starting parameter can also include an emergency stop signal of the oil gas lubrication system, and a fourth determination result is obtained by determining whether the emergency stop signal exists; and the oil gas starting parameter is determined to meet the starting condition according to the first determination result, the second determination result, the third determination result and the fourth determination result. When the first determination result indicates that the oil pressure is in the preset oil pressure threshold interval, the second determination result indicates that the gas pressure is in the preset gas pressure threshold interval, the third determination result indicates that the lubricating oil level is greater than the liquid level threshold, and the fourth determination result indicates that the emergency stop signal does not exist, the oil gas starting parameter is determined to meet the starting condition; otherwise, the oil gas starting parameter is determined to not meet the starting condition.

[0113] Of course, the above starting condition is not unique, and those skilled in the art can adjust it according to the specific application scene, for example, one or more of the above conditions can be omitted, or other determination conditions can be added on this basis.

[0114] The following refers to Figure 3 , a possible implementation process of the present application is introduced.

[0115] As Figure 3 shown, in a possible implementation process:

[0116] S201, at the first start after a new power-on, the oil pressure, gas pressure and lubricating oil level are first obtained.

[0117] S203, according to the oil pressure, gas pressure and lubricating oil level, it is determined whether the starting condition is met, if yes, S205 is executed; otherwise, S215 is executed.

[0118] S205, the oil gas lubrication system is started, and after waiting for 40s, pre-lubrication is performed, the oil gas lubrication system is controlled to supply oil gas to the first bearing box and the second bearing box, and the control is continued for 3min.

[0119] S207, after 3min, intermittent lubrication control is started, and the oil gas lubrication system is first controlled to start injecting oil gas to the first bearing box and the second bearing box.

[0120] S209, it is determined whether the injection time of oil gas is greater than or equal to 5s, if yes, S211 is executed; otherwise, if not, S207 is returned to continue to be executed.

[0121] S211, controlling the oil-gas lubrication system to stop injecting oil-gas.

[0122] S213, judging whether the time of stopping injecting oil-gas is greater than or equal to 360s, if yes, returning to execute S207; otherwise, if no, returning to continue to execute S211.
