Description

Technical Field

[0001] The present invention relates to the technical field of wire cutting, and in particular to a wire cutting machine bearing box lubrication control method, medium, device and wire cutting machine. Background Art

[0002] Wire cutting is a processing method in which the cutting wire is moved back and forth at high speed and moves relative to the workpiece to be cut (such as photovoltaic silicon rods, semiconductors, silicon carbide, sapphire, magnetic materials, etc.) to make the cutting wire cut the workpiece to be cut.

[0003] The main roller assembly is one of the key components to complete the cutting. The two ends of the main roller are supported by the bearing box. The cutting wire is wound on the main roller to form a wire net to cut the workpiece to be cut. In order to ensure the rotation effect of the bearing box, the bearing box needs to be lubricated during the cutting process. The current main lubrication method is step-by-step lubrication, that is, the bearing box is lubricated once every fixed time interval. However, due to the high speed, high torque, and high response of the wire cutting machine during the cutting process, the step-by-step lubrication method will cause lubricant splashing and other phenomena. Therefore, more lubricant needs to be filled each time to prevent insufficient lubrication of the bearing box from affecting the lubrication effect.

[0004] Accordingly, the art needs a new technical solution to solve the above problems. Summary of the invention

[0064] The preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application. For example, although the detailed steps of the method of the present application are described in detail below, without departing from the basic principles of the present application, those skilled in the art can combine, split and change the order of the following steps, and the modified technical scheme does not change the basic concept of the present application, and therefore also falls within the scope of protection of the present application.

[0065] First refer to Figure 1 and Figure 2 , describes X of the present application. Wherein, Figure 1 for.

[0066] It should be noted that, in the description of this application, the terms "first", "second", "third", "fourth", "fifth" and "sixth" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0068] First refer to Figure 1 , the lubrication system of the present application is introduced.

[0069] like Figure 1 As shown, the lubrication system of the present application includes an oil circuit assembly 1, an air circuit assembly 2 and an oil-gas mixing valve 3. The oil circuit assembly 1 and the air circuit assembly 2 are simultaneously connected to the oil-gas mixing valve 3, the oil-gas mixing valve 3 is connected to the bearing box, the oil circuit assembly 1 is used to provide lubricating oil, the air circuit assembly 2 is used to provide compressed gas, and the oil-gas mixing valve 3 is used to mix the lubricating oil and the compressed gas into oil and gas.

[0070] During the application process, a bearing box is connected to each end of the main roller of the wire cutting machine to support the rotation of the main roller. When receiving the instruction to lubricate the bearing box, the oil circuit assembly 1 and the air circuit assembly 2 are controlled to provide lubricating oil and compressed air to the oil-gas mixing valve 3 respectively. The lubricating oil and compressed air are mixed in the oil-gas mixing valve 3 to become oil and gas. The mixed oil and gas are discharged by the oil-gas mixing valve 3. The discharged lubricating oil forms a continuous liquid flow before reaching the bearing box, and is sent into the bearing box along with the compressed air for lubrication.

[0071] Further references Figure 1 In a preferred embodiment, the lubrication system includes an oil circuit assembly 1, an air circuit assembly 2, and an oil-air mixing valve 3.

[0072] Specifically, the oil circuit assembly 1 includes an oil pump 11, a power supply valve, a first filter 12, an oil pressure detection sensor and an oil flow sensor. Figure 1 Only the oil pump 11 and the first filter 12 are shown. The oil pump 11 provides lubricating oil, and the first filter 12 cleans and filters the lubricating oil. The inlet of the first filter 12 is connected to the outlet of the oil pump 11, and the outlet of the first filter 12 is connected to the power supply valve. The power supply valve is used to control the on-off and oil pressure of the oil circuit, and the outlet of the power supply valve is connected to the oil-gas mixing valve 3. The oil pressure sensor and the oil flow sensor are arranged between the power supply valve and the oil-gas mixing valve 3. The oil pressure detection sensor is used to detect the oil pressure of the lubricating oil entering the oil-gas mixing valve 3, and the oil flow sensor is used to detect the flow of the lubricating oil entering the oil-gas mixing valve 3. Preferably, the power supply valve is a pressure regulating valve or an electrically controlled valve with an adjustable opening, and the pressure of the oil circuit is adjusted by changing the opening.

[0073] The gas circuit assembly 2 includes an air pump, an air supply valve 21, a second filter, an air pressure detection sensor and an air flow sensor. The air pump is used to provide clean compressed gas. The second filter cleans and filters the compressed gas, the inlet of the second filter is connected to the outlet of the air pump, the outlet of the second filter is connected to the air supply valve 21, the outlet of the air supply valve 21 is connected to the oil-gas mixing valve 3, and the air supply valve 21 is used to control the on-off of the gas circuit and adjust the pressure of the gas circuit. The air pressure detection sensor is arranged between the air supply valve 21 and the oil-gas mixing valve 3, the air pressure detection sensor is used to detect the air pressure of the gas entering the oil-gas mixing valve 3, and the air flow sensor is used to detect the flow of the gas entering the oil-gas mixing valve 3. Preferably, the air supply valve 21 is a pressure regulating valve or an electrically controlled valve with an adjustable opening, and the pressure of the gas circuit is adjusted by changing the opening.

[0074] The main function of the oil-gas mixing valve 3 is to mix the lubricating oil and compressed air to form oil and gas of a certain concentration, and then transport the mixed oil and gas to the bearing box to lubricate the bearing box. The oil-gas mixing valve 3 includes an oil inlet, an air inlet, and an oil-gas mixing outlet. The oil inlet is connected to the power supply valve, the air inlet is connected to the air supply valve 21, and the oil-gas mixing outlet is connected to the bearing box. Preferably, the lubrication system also includes a nozzle 4, which is installed on the bearing box, the inlet of the nozzle 4 is connected to the oil-gas mixing outlet of the oil-gas mixing valve 3, and the outlet of the nozzle 4 is connected to the inside of the bearing box, which is used to spray oil and gas lubrication on the bearing inside the bearing box. Figure 1 In the illustrated embodiment, the oil-gas mixing valve 3 has four oil-gas mixing outlets, each of which is connected to a nozzle 4. In other words, the oil-gas mixing valve 3 can simultaneously inject oil and gas into four bearings in a bearing box. Usually, one oil-gas mixing valve 3 corresponds to multiple bearings in a bearing box, and the number of oil-gas mixing valves 3 is set corresponding to the number of bearing boxes.

[0075] It should be noted that the above preferred implementations are only used to illustrate the principles of the present application and are not intended to limit the scope of protection of the present application. Without departing from the principles of the present application, those skilled in the art may adjust the above settings so that the present application can be applied to more specific application scenarios.

[0076] For example, in an alternative embodiment, the specific configuration 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, oil pressure detection sensor, oil flow sensor, etc. can be omitted in the oil circuit assembly 1. For another example, the air pressure detection sensor, air flow sensor, etc. can also be omitted in the gas circuit assembly 2.

[0077] For example, in another replaceable embodiment, although the above embodiment is introduced in combination with the lubricant being an oil-gas mixture of lubricating oil and compressed air, the specific form of the lubricant is not limited to this, and technical personnel in this field can also make adjustments as long as the bearing box can be lubricated. For example, the lubricant can also be a separate lubricating oil, or a grease with a certain fluidity, etc., and the structure of the lubrication system also needs to be adjusted accordingly.

[0078] For another example, in another replaceable embodiment, although the pressure regulation and on-off of the oil circuit assembly 1 are both achieved through the power supply valve, this is not the only option. Those skilled in the art can separate the pressure regulation and on-off functions, such as achieving on-off of the pressure assembly through a solenoid valve and achieving pressure regulation of the pressure assembly through a pressure regulating device. Similarly, the air supply valve 21 in the air circuit assembly 2 can also be replaced by a solenoid valve and a pressure regulating device.

[0079] For another example, in another alternative embodiment, although the above-mentioned oil-gas mixing valve 3 is described in combination with an example of having four oil-gas mixing outlets, the number of specific oil-gas mixing outlets of the oil-gas mixing valve 3 can be adjusted based on the number of bearings in the bearing box in a specific application scenario, such as the number can also be one, two, three, five or more, and this adjustment does not deviate from the principle of the present application. Of course, one oil-gas mixing valve 3 can also correspond to two or even three bearing boxes, and this setting method does not deviate from the principle of the present application.

[0080] Of course, the above-mentioned replaceable implementations, as well as the replaceable implementations and the preferred implementations, can be used in a cross-coordinated manner to combine new implementations to suit more specific application scenarios.

[0081] Refer to the following Figure 2 , the wire cutting machine bearing box lubrication control method of the present application is introduced.

[0082] like Figure 2 As shown, in order to solve the problems of poor lubrication effect and large lubricant consumption in the existing bearing box lubrication method, the wire cutting machine bearing box lubrication control method of the present application includes:

[0083] S101, obtaining the real-time rotation speed of the main roller. For example, the real-time rotation speed of the main roller can be obtained through an encoder of a motor connected to the main roller transmission or an external speed sensor for detecting the rotation speed of the main roller.

[0084] S103, determining the magnitude of the real-time rotation speed and the preset rotation speed threshold. For example, the magnitude of the real-time rotation speed and the preset rotation speed threshold is determined by calculating the difference or ratio between the real-time rotation speed and the preset rotation speed threshold. The preset rotation speed threshold may be factory set, manually input by a staff member, or selected based on the cutting process parameters of the wire cutting machine.

[0085] S105, when the real-time rotation speed is less than the preset rotation speed threshold, control the lubrication system to inject lubricant into the bearing box. For example, when the real-time rotation speed is less than the preset rotation speed threshold, the rotation speed of the main roller is relatively low, and the power supply valve and the air supply valve of the lubrication system are controlled to open, the oil pump supplies oil to the oil-gas mixing valve, the air pump supplies air to the oil-gas mixing valve, and the lubricating oil and compressed air are mixed in the oil-gas mixing valve and supplied to the bearing box to lubricate the bearing box.

[0086] S107, when the duration of lubricant injection reaches the first preset duration, the lubrication system is controlled to stop injecting lubricant into the bearing box. For example, when it is detected that the duration of lubricant injection reaches the first preset duration, the power supply valve and the air supply valve are controlled to be closed, and the oil pump stops supplying oil to the oil-gas mixing valve, and the air pump stops supplying air to the oil-gas mixing valve at the same time, and the lubrication process ends. The first preset duration can be factory preset, manually input by the staff, or determined based on the cutting process parameters.

[0087] The above control method of the present application can realize lubricant filling when the main roller is running at a low speed or stopped by controlling the lubrication system to inject lubricant into the bearing box when the real-time speed of the main roller is less than the preset speed threshold, thereby achieving a more sufficient lubrication effect, reducing the situation where the injected lubricant splashes when the main roller speed is too high and causes insufficient lubrication, and the better lubrication effect can ensure that the bearing has a longer service life under high speed, heavy load, acceleration and deceleration, etc. In addition, compared with the existing step-by-step lubrication, the amount of lubricant injected at a single time can be greatly reduced due to the more targeted selection of the timing of lubricant injection, so that there is a certain advantage in lubricant consumption.

[0088] The preferred implementation of the control method of the present application is introduced below.

[0089] In one embodiment, the preset speed threshold is any value in the range of 0 to 1000 rpm, and more preferably, the preset speed threshold is any value in the range of 0 to 500 rpm; the first preset duration is any value in the range of 0.1s to 2s. For example, the lower the speed of the main roller, the better the injection effect of the oil and gas, and the smaller the probability of oil and gas splashing. Therefore, when the preset speed is close to or equal to zero, the lubrication operation is performed, and the effect is better. The first preset duration is more preferably any value in the range of 0.5s to 1s. If the time is too short, effective lubrication cannot be formed. If the time is too long, the oil and gas will splash as the speed of the main roller increases during the reciprocating motion, reducing the lubrication effect.

[0090] Of course, the specific values ​​of the preset speed threshold and the first preset duration are not fixed, and those skilled in the art can adjust them based on specific application scenarios.

[0091] In one embodiment, before the step of "obtaining the real-time rotational speed of the main roller", the control method also includes: detecting whether the lubrication interval of the bearing box reaches a preset interval; when the lubrication interval reaches the preset interval, obtaining the real-time rotational speed of the main roller.

[0092] For example, during the cutting process of the wire cutting machine, the main roller drives the cutting wire wound thereon to make reciprocating motion. Usually, the time of one reciprocating motion is between a few seconds and tens of seconds. If the main roller performs lubrication operation every time the speed is reduced to near zero during the reciprocating motion, it will lead to over-lubrication and unnecessary waste of lubricant. For this reason, before obtaining the real-time rotation speed of the main roller, the present application first determines whether the lubrication interval of the bearing box reaches the preset interval, that is, it determines whether the interval time from the current distance to the last lubrication of the bearing box is enough to reach the preset interval, and only when it reaches it, the bearing box is lubricated. Preferably, the preset interval is any value between 200s and 500s. For example, the preset interval can be 360s. In other words, after controlling the lubrication system to lubricate the bearing box once, the bearing box is lubricated again after an interval of 360s, so that the oil and gas injected previously can better adhere to the surface of the bearing box, thereby improving the lubrication capacity and reliability of the equipment.

[0093] By obtaining the real-time rotation speed of the main roller only when the lubrication interval reaches the preset interval, intermittent automatic supply of lubricant can be achieved, avoiding lubricant filling every time the main roller is at a low speed, resulting in excessive lubrication due to excessive lubrication times.

[0094] Of course, the specific value of the preset interval duration is not fixed, and those skilled in the art can adjust it based on the specific application scenario.

[0095] In a more preferred embodiment, the preset speed threshold, the first preset duration and the preset interval duration are determined based on at least one of the specifications of the main roller, the specifications of the bearing box, the specifications of the bearing configured in the bearing box and the cutting process of the wire cutting machine.

[0096] For example, for main rollers of different diameters, bearing boxes of different specifications, bearings of different specifications, and different cutting processes (such as different feeding methods, feed amounts, division of cutting stages, number of simultaneous cutting, etc.), the rotation speed of the main roller, the load-bearing capacity, and the degree of wear of the bearing box are all different, and the corresponding required degree of lubrication and lubrication frequency are also different. In this regard, the present application can be tested based on the above parameters to test the lubrication effect of the oil and gas supply method corresponding to different preset speed thresholds, first preset durations, and preset interval durations under each different working condition, and select the better test results as the standard value under the working condition to form a comparison table or fitting formula. Thus, in the actual application process, for each different application scenario, there is a corresponding preset speed threshold, first preset duration, and preset interval duration.

[0097] The above-mentioned configuration can realize lubricant filling in different application scenarios and improve the injection accuracy of the lubricant.

[0098] Of course, those skilled in the art may also select only one or some of the above-mentioned numerous influencing parameters to determine the preset speed threshold, the first preset duration and the preset interval duration.

[0099] In one embodiment, before the step of "controlling the lubrication system to inject lubricant into the bearing box", the control method further includes: detecting whether the startup state of the lubrication system is the first startup after the new power-on; if it is detected that the startup state is the first startup after the new power-on, controlling the lubrication system to perform a pre-lubrication operation. Specifically, the step of "controlling the lubrication system to perform a pre-lubrication operation" further includes: controlling the lubrication system to inject lubricant into the bearing box and continuing for a second preset duration. The second preset duration is any value between 100s and 300s. Preferably, the second preset duration is 180s.

[0100] For example, after the wire cutting machine is shut down for a period of time and restarted, the pipeline of the lubrication system is filled with air. At this time, when the lubrication system is started again, the lubrication system is controlled to perform a 180-second pre-lubrication operation, that is, the power supply valve and the air supply valve are controlled to open and last for 180 seconds, and the air and other impurities in the lubrication pipeline are discharged by injecting oil and gas into the lubrication pipeline, so that the lubricating oil and gas fill the pipeline, and at the same time, it also plays a role in cleaning the pipeline and the bearing box. After that, the above lubrication operation is circulated.

[0101] By controlling the lubrication system to perform pre-lubrication operation at the first start after power-on, the air in the lubrication pipeline can be discharged, so that the lubricant fills the pipeline. At the same time, it can also clean the pipeline and bearing box to improve the lubrication effect.

[0102] Of course, the above-mentioned pre-lubrication operation is not necessary, and those skilled in the art can make a choice based on the specific application scenario. In addition, the specific value of the second preset duration is not restrictive, and those skilled in the art can adjust it.

[0103] In one embodiment, the control method further includes: in the process of controlling the lubrication system to inject lubricant into the bearing box, detecting whether the supply parameters of the lubrication system meet the supply conditions; when it is detected that the supply parameters meet the supply conditions, controlling the lubrication system to continue injecting lubricant into the bearing box; when it is detected that the supply parameters do not meet the supply conditions, controlling the lubrication system to output an alarm message. Specifically, the supply parameters include the oil pressure and oil flow of the oil circuit component, the air pressure and air flow of the air circuit component, and the supply conditions include the following conditions:

[0104] (1) determining whether the oil pressure is within a preset oil pressure threshold range, and obtaining a first determination result;

[0105] (2) determining whether the oil flow rate is within a preset oil flow rate threshold range, and obtaining a second determination result;

[0106] (3) determining whether the air pressure is within a preset air pressure threshold range, and obtaining a third determination result;

[0107] (4) determining whether the air flow rate is within a preset air flow rate threshold range, and obtaining a fourth determination result;

[0108] Then, according to the first judgment result, the second judgment result, the third judgment result and the fourth judgment result, it is detected whether the supply parameter meets the supply condition.

[0109] Further, when the first judgment result indicates that the oil pressure is in a preset oil pressure threshold range, and the second judgment result indicates that the oil flow is in a preset oil flow threshold range, and the third judgment result indicates that the air pressure is in a preset air pressure threshold range, and the fourth judgment result indicates that the air flow is in a preset air flow threshold range, it is determined that the supply parameters meet the supply conditions; otherwise, it is determined that the supply parameters do not meet the supply conditions.

[0110] For example, when the oil pressure is not in the preset oil pressure threshold interval, the lubricating oil supply is unstable, which is not conducive to providing an appropriate and stable amount of lubricating oil. Similarly, when the air pressure is not in the preset air pressure threshold interval, the compressed air supply is unstable, which is not conducive to providing an appropriate and stable amount of compressed air. When the flow rate of the lubricating oil is not in the preset oil flow threshold interval, the amount of lubricating oil provided in the same time is insufficient or excessive. Similarly, when the flow rate of the compressed air is not in the preset air flow threshold interval, the amount of compressed air supplied in the same time is insufficient or excessive. If the above situation occurs, that is, at least one of the above four conditions is not met, it is determined that the supply parameters do not meet the supply conditions, and the lubrication system is controlled to output an alarm message, such as an audible / light / text alarm message, to prompt the user that the system has a fault and needs to be checked in time. If all of the above supply conditions are met, it is determined that the supply parameters meet the supply conditions, and the lubrication system is controlled to continue to inject oil and gas into the bearing box.

[0111] By controlling the lubrication system to inject lubricant into the bearing box when the supply parameters meet the supply conditions, the oil circuit components and the gas circuit components can work in a better state, which is beneficial to improving the operating stability of the lubrication system. When the supply parameters do not meet the supply conditions, the lubrication system is controlled to output an alarm message, which can avoid lubrication system failure and help improve the lubrication effect.

[0112] Of course, the above control method is not the only one. Those skilled in the art can choose whether to execute the above steps or adjust the above steps based on the specific application scenario. For example, one or more of the above four conditions can be selected. For another example, other judgment conditions can be added on the basis of the above conditions to assist in judging the stability of the lubrication system. For example, the liquid level of the lubricating oil in the oil pump can be judged. When the liquid level is too low, the amount of lubricating oil is reduced and needs to be replenished, otherwise the oil pump may run idle.

[0113] In one embodiment, the control method further includes: in the process of controlling the lubrication system to inject lubricant into the bearing box, detecting whether the injection parameters of the oil and gas meet the injection conditions; when it is detected that the injection parameters meet the injection conditions, controlling the lubrication system to continue injecting lubricant into the bearing box; when it is detected that the injection parameters do not meet the injection conditions, controlling the lubrication system to output an alarm message. Specifically, the injection parameters include the mixed pressure and mixed flow of the oil and gas, and the injection conditions include:

[0114] (5) determining whether the mixed pressure is within a preset mixed pressure threshold range, and obtaining a fifth determination result;

[0115] (6) determining whether the mixed flow rate is within a preset mixed flow rate threshold range, and obtaining a sixth determination result;

[0116] Then, according to the fifth judgment result and the sixth judgment result, it is detected whether the injection parameters meet the injection conditions.

[0117] Further, when the fifth judgment result indicates that the mixed pressure is in the preset mixed pressure threshold interval, and when the sixth judgment result indicates that the mixed flow is in the preset mixed flow threshold interval, it is determined that the injection parameters meet the injection conditions; otherwise, it is determined that the injection parameters do not meet the injection conditions.

[0118] For example, when the pressure of the mixed oil and gas is not within the preset mixed pressure threshold interval, the oil and gas supply is unstable, which is not conducive to providing an appropriate and stable oil and gas mixture, affecting the lubrication effect. When the flow rate of the mixed oil and gas is not within the preset mixed flow threshold interval, insufficient or excessive oil and gas provided in the same time will affect the lubrication effect. If at least one of the above conditions is not met, it is determined that the injection parameters do not meet the injection conditions, and the lubrication system is controlled to output an alarm message, such as an audible / light / text alarm message, to prompt the user that the system has a fault and needs to be checked in time. If all of the above judgment conditions are met, it is determined that the injection parameters meet the injection conditions, and the lubrication system is controlled to continue injecting oil and gas into the bearing box.

[0119] By controlling the lubrication system to continue injecting lubricant into the bearing box when the injection parameters meet the injection conditions, the injection stability of the mixed oil and gas can be improved, which is beneficial to improving the lubrication effect. When the injection parameters do not meet the injection conditions, the lubrication system is controlled to output an alarm message to avoid invalid lubrication.

[0120] Those skilled in the art can understand that the above control method is only preferred, and those skilled in the art can choose whether to apply the above control logic based on the actual application scenario. Of course, the above judgment conditions can also be deleted or added, and the adjusted schemes do not deviate from the principles of this application.
