Description

Technical Field

[0001] This application relates to the field of industrial automation technology, and in particular to an electric cylinder oil injection device and an electric cylinder oil injection control system. Background Technology

[0002] In the development of industrial automation, equipment lubrication and maintenance are crucial. Large equipment, such as scaffolding robots, often uses manual lubrication, requiring overhead cranes to lubricate the electric cylinders, which is inefficient and prone to errors.

[0003] Existing lubrication technologies mainly include spring-type and electronic lubricators. Spring-type lubricators have uncontrollable lubrication, are prone to overfilling, and do not alarm when the oil tank is empty; electronic lubricators lubricate according to a set time and amount, and the timer continues even when the electric cylinder is not moving, which can also lead to overfilling, and similarly, there is no alarm when the oil tank is empty.

[0004] Excessive lubrication not only wastes resources and pollutes the environment—for example, when a robotic overhead conveyor handles goods in a smart warehouse, leaking lubricating oil can contaminate the goods, clog vents, and shorten the lifespan of the electric cylinder—there is an urgent need for a new, precise lubrication technology to solve many of the problems with existing technologies and meet the needs of industrial production.

It should also be understood that the terms “comprising / including” or “having,” etc., specify the presence of the stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. Meanwhile, the term “and / or” as used in this specification includes any and all combinations of the associated listed items.

[0041] In one exemplary embodiment, such as Figure 1 As shown, this application provides an electric cylinder oil injection device, which includes an oil injection assembly 2, a first switching circuit 4, and a controller 6. The oil injection assembly 2 is used to inject oil into the electric cylinder 300; the first switching circuit 4 is connected in series in the power supply circuit of the oil injection assembly 2; the controller 6 is connected to the first switching circuit 4, and when the electric cylinder 300 operates for a certain duration, the controller 6 outputs a first level signal to the first switching circuit 4 to trigger the first switching circuit 4 to close.

[0042] The lubrication assembly 2 is the part of the electric cylinder lubrication equipment directly responsible for supplying lubricating oil to the electric cylinder 300. Its specific structure may include a container for storing lubricating oil (such as an oil tank) and a conveying device (such as an oil pump 24, oil pipe, and nozzle) for transporting lubricating oil from the container to the lubrication points inside the electric cylinder 300. Its main function is to accurately inject an appropriate amount of lubricating oil into the electric cylinder 300 according to certain requirements during equipment operation, ensuring that all moving parts of the electric cylinder 300 receive sufficient lubrication during operation, reducing friction and wear, thereby ensuring the normal operation of the electric cylinder 300 and extending its service life. Different types of lubrication assemblies 2 may differ in lubrication methods (such as pressure lubrication, gravity lubrication, etc.), lubrication accuracy, and lubrication speed; the specific design depends on the overall requirements of the equipment and the application scenario. The first switching circuit 4 plays the role of controlling the power supply of the lubrication assembly 2 in the entire electric cylinder lubrication equipment. It is connected in series in the power supply circuit of the lubrication assembly 2, and its main function is to determine whether to conduct based on the signal output by the controller 6, thereby controlling whether the lubrication assembly 2 is energized and operates. When the controller 6 outputs a first-level signal, the first switch circuit 4 closes, connecting the power supply circuit to the oil injection component 2, and the oil injection component 2 begins to operate for oil injection. Conversely, when the switch circuit is open, the oil injection component 2 stops receiving power and stops oil injection. The first switch circuit 4 can be composed of one or more electronic switching elements (such as transistors, relays, etc.). Its specific circuit structure and component selection will affect the switch's response speed, current carrying capacity, control method, and other performance indicators. These indicators need to match the power requirements of the oil injection component 2 and the control logic of the entire device. The controller 6 is responsible for the logic control and decision-making of the entire oil injection process. It is connected to the first switch circuit 4 and monitors the working status of the electric cylinder 300 (such as working time) and determines whether to trigger the oil injection operation based on the preset timing duration. When the working time of the electric cylinder 300 reaches the timing duration, the controller 6 outputs a first-level signal to the first switch circuit 4, controlling its closure and starting the oil injection component 2 for oil injection. The controller 6 can be a microcontroller, a programmable logic controller 6, or other electronic devices or components with control functions.

[0043] For example, when the device starts, the lubrication assembly 2 is connected in series with the first switching circuit 4 in the power supply circuit, and the first switching circuit 4 is initially in the open state. After the electric cylinder 300 starts working, the controller 6 continuously monitors the operating status of the electric cylinder 300, specifically by receiving signals from relevant sensors on the electric cylinder 300 (such as motion sensors, working time counters, etc.). These signals can accurately reflect whether the electric cylinder 300 is in working state and the cumulative working time. When the controller 6 detects that the working time of the electric cylinder 300 reaches the preset time, the logic circuit inside the controller 6 generates a first level signal (e.g., a high level signal) and outputs it to the first switching circuit 4. After receiving the first level signal output by the controller 6, the electronic switching element inside the first switching circuit 4 is activated, causing the first switching circuit 4 to close. At this time, the power supply circuit of the lubrication assembly 2 is connected, the lubrication assembly 2 starts working, and lubricating oil is injected from the storage container of the lubrication assembly 2 into the lubrication points inside the electric cylinder 300 through a conveying device at a certain pressure and flow rate, thereby realizing the lubrication operation of the electric cylinder 300. During the oil injection process, the oil injection component 2 continues to work until the oil injection task is completed or the oil injection stops according to other control logic (such as reaching the preset oil injection volume, receiving a stop oil injection signal, etc.).

[0044] The aforementioned electric cylinder lubrication system uses a controller that precisely monitors the cylinder's operating time, triggering the lubrication component only after the cylinder has reached the designated lubrication duration. This ensures a close match between the lubrication timing and the cylinder's actual lubrication needs. This effectively avoids unnecessary lubrication, precisely controls the amount of lubricating oil injected, and allows the lubricating oil to provide just the right amount of lubrication during cylinder movement, preventing leakage due to over-lubrication. This not only significantly reduces lubricating oil waste and lowers operating costs, but also prevents environmental pollution (such as goods in smart warehouses) caused by lubricating oil leakage, and avoids shortened cylinder lifespan caused by leaked lubricating oil clogging the vent. This strongly guarantees the stable operation of the electric cylinder and the efficient, clean, and sustainable operation of industrial production.

[0045] In one exemplary embodiment, such as Figure 2 As shown, the controller 6 includes a timer 62 and a drive module 64. The timer 62 is used to keep track of time when the electric cylinder 300 is working, and outputs a second level signal when the timing duration reaches the set time. The drive module 64 is connected to the first switch circuit 4 and the timer 62 respectively. When the drive module 64 receives the second level signal, it outputs a first level signal to the first switch circuit 4.

[0046] The timer 62 is used to accurately measure time when the electric cylinder 300 is in operation. Timing starts from the moment the electric cylinder 300 begins operation, continuously accumulating the working time in preset time units (such as seconds, milliseconds, etc.). When the accumulated time reaches the preset time limit, the timer 62 generates a level change signal, i.e., a second-level signal (e.g., a high-level signal), as a notification signal that the time trigger condition has been met. This allows the subsequent drive module 64 to perform corresponding operations based on this signal, thereby controlling the start of the oil injection process. This ensures that the oil injection operation is precisely executed at the time required by the actual operation of the electric cylinder 300, achieving the purpose of oil injection based on the movement of the electric cylinder 300. The drive module 64 plays the role of signal conversion and power driving in the entire controller 6. On the one hand, it receives the second level signal from the timer 62, which serves as a trigger command, indicating that the working time of the electric cylinder 300 has met the oil injection conditions. On the other hand, it is connected to the first switch circuit 4 and is responsible for converting the received timer 62 signal into a first level signal suitable for driving the first switch circuit 4 (such as converting a weak logic level signal into a level and power signal required to turn on the electronic switch element in the first switch circuit 4), and outputting it to the first switch circuit 4, thereby controlling the on / off of the power supply circuit of the oil injection component 2, realizing precise control of the working state of the oil injection component 2, and ensuring that the entire oil injection equipment operates normally according to the preset logic.

[0047] For example, taking the drive module 64 as a comparator, during device initialization, the timer 62 and the comparator are initialized, and the first switch circuit 4 is in the off state. When the electric cylinder 300 starts working, the timer 62 starts timing synchronously. When the timer 62 reaches the set duration, its output level changes, generating a second level signal (assuming it is high). This high-level signal is input to one input terminal of the comparator (e.g., the positive input terminal), and the other input terminal of the comparator (e.g., the negative input terminal) is connected to a reference voltage source, whose reference voltage is set to the trigger threshold voltage corresponding to the timer 62 outputting a high level. Since the input high-level signal is greater than the reference voltage at this time, the comparator output level flips, outputting a first level signal (e.g., high level) to the first switch circuit 4. After receiving the high-level signal, the electronic switching element (e.g., a transistor) in the first switch circuit 4 conducts, the power supply circuit of the oil injection component 2 is closed, and the oil injection component 2 starts working, injecting lubricating oil into the electric cylinder 300. Alternatively, taking the drive module 64 as a trigger, before device startup, the timer 62 and the trigger are initialized, and the first switch circuit 4 is in the off state. When the electric cylinder 300 starts working, timer 62 starts timing synchronously. When the timing reaches the set duration, timer 62 outputs a second-level signal (e.g., high level). This high-level signal is used as a trigger signal input to the clock input (CLK) of the flip-flop. The data input (D) of the flip-flop is preset to high level (indicating that the oil filling operation is enabled). Under the triggering of the rising edge of the clock signal (i.e., when timer 62 outputs a high-level signal), the output (Q) of the flip-flop outputs a first-level signal (high level) to the first switching circuit 4. After receiving the high-level signal, the relay or transistor and other electronic switching elements in the first switching circuit 4 activate, turning on the power supply circuit of the oil filling assembly 2, and the oil filling assembly 2 starts working to perform oil filling.

[0048] In this embodiment, a timer precisely times the operation and outputs a second-level signal at the appropriate time, closely linking the oil injection timing with the actual working duration of the electric cylinder. This ensures that the oil injection operation accurately matches the lubrication requirements of the electric cylinder, avoiding the problems of over- or under-oil injection caused by the disconnect between the traditional oil injection method and the actual movement. The drive module, as a key component for signal conversion and power driving, whether implemented as a comparator or a trigger, effectively converts the timer signal into a first-level signal adapted to the first switching circuit. This enables precise control of the power supply circuit for the oil injection component, improving the accuracy and reliability of oil injection, effectively reducing lubricant waste and leakage, preventing environmental pollution, extending the service life of the electric cylinder, reducing equipment maintenance costs, and enhancing the performance and intelligence of the entire electric cylinder oil injection equipment, thus ensuring efficient and stable operation in industrial production.

[0049] In one exemplary embodiment, such as Figure 2As shown, the device also includes a power supply module 8 and a second switching circuit 10. The power supply module 8 is connected to the timer 62 and the electric cylinder 300 respectively, and the power supply module 8 is also connected to the oil injection assembly 2 through the first switching circuit 4; the second switching circuit 10 is connected in series in the common circuit on which the power supply module 8 supplies power to the timer 62 and the electric cylinder 300.

[0050] For example, in the initial state of the equipment, the power supply module 8 is in standby mode, the second switch circuit 10 is in the off state, and the first switch circuit 4 is also in the off state. At this time, the timer 62 has not started timing, the electric cylinder 300 and the oil injection component 2 are not powered, and the entire system is in a static waiting state. When it is necessary to start the electric cylinder 300, an external control signal (such as the operator pressing the start button or receiving a start command from the host computer) causes the second switch circuit 10 to close. The power supply module 8 starts supplying power to the electric cylinder 300 and the timer 62, and the electric cylinder 300 starts running immediately. At the same time, the timer 62 starts timing synchronously at the moment of power supply, accumulating the working time of the electric cylinder 300 in a preset time unit (such as seconds, milliseconds, etc.), ensuring that the monitoring of its working time begins accurately from the moment the electric cylinder 300 starts working, providing a precise time reference for subsequent precise oil injection control. As the electric cylinder 300 continues to work, the timer 62 continues to time. When the timer 62 reaches the preset timing duration, it outputs a second level signal (such as a high level). The signal is transmitted to the drive module 64 (such as a comparator or trigger, whose working principle is as described above). The drive module 64 outputs a first-level signal (such as a high level) to the first switching circuit 4 based on this signal. After receiving the first-level signal, the electronic switching element (such as a transistor or relay) in the first switching circuit 4 activates, causing the first switching circuit 4 to close. At this time, the power supply module 8 supplies power to the oil injection assembly 2 through the closed first switching circuit 4. The oil injection assembly 2 starts to work, injecting an appropriate amount of lubricating oil into the internal lubrication points of the electric cylinder 300 through a delivery device (such as an oil pump 24, oil pipe, or fuel injector) according to the design requirements, thereby achieving precise oil injection operation of the electric cylinder 300.

[0051] In this embodiment, by connecting the second switching circuit in series with the common power supply circuit, the timer can synchronously count when the electric cylinder starts, ensuring the accuracy and timeliness of monitoring the working time of the electric cylinder. This provides a reliable time basis for subsequent precise oil injection, effectively avoiding the problem of oil injection being too early or too late due to timing errors. Simultaneously, the power supply module is connected to the oil injection component through the first switching circuit, realizing precise start-stop control of the oil injection component based on the actual movement of the electric cylinder, avoiding the drawbacks of uncontrolled oil injection in traditional oil injection methods. This not only improves the accuracy of oil injection, reduces lubricant waste and seepage, and lowers the risk of environmental pollution, but also extends the service life of the electric cylinder, reduces equipment failures caused by improper lubrication, improves the overall stability, reliability, and intelligence level of the equipment, reduces maintenance costs, and improves the efficiency and quality of industrial production.

[0052] In one exemplary embodiment, such as Figure 3 As shown, the oil injection assembly 2 includes an oil tank 22 and an oil pump 24. The oil outlet of the oil tank 22 is connected to the chamber of the electric cylinder 300 through an oil supply pipe; the oil pump 24 is located on the oil supply path from the oil tank 22 to the electric cylinder 300, and the power supply terminal of the oil pump 24 is connected to the power supply module 8 through the first switch circuit 4.

[0053] In this embodiment, the oil tank serves as a storage container for lubricating oil, providing a stable oil source for oil injection. It is connected to the electric cylinder chamber via an oil delivery pipe, ensuring that the lubricating oil can be smoothly delivered to the lubrication points inside the electric cylinder. The oil pump is located on the oil delivery path, and its power supply is controlled by the first switching circuit, enabling the oil injection process to start and stop precisely according to controller commands. This achieves on-demand oil injection, effectively improving the accuracy of oil injection and avoiding the problems of over- or under-injection caused by the inability to accurately control the amount of oil injected in traditional oil injection methods.

[0054] In one exemplary embodiment, the first switching circuit 4 is a relay.

[0055] In this embodiment, a relay is used as the first switching circuit 4. Based on the relay's excellent electrical isolation characteristics, it can effectively isolate electrical interference between the controller 6 and the power supply circuit of the oil injection component 2, ensuring the stable operation of the controller 6 and preventing it from being affected by factors such as the high current of the oil injection component 2, thus improving the reliability of the entire device. It can withstand a large current load and is suitable for devices like the oil injection component 2 that may require high-power drive, ensuring stable conduction of the power supply circuit and enabling the oil injection component 2 to operate normally. The relay's switching action is clear and reliable, and its response speed meets the oil injection control requirements. It can accurately control the on / off state of the power supply circuit of the oil injection component 2 based on the signal from the controller 6, thereby precisely controlling the timing and process of oil injection. This allows for precise oil injection based on the actual movement of the electric cylinder 300, further reducing the risk of lubricating oil leakage, extending the life of the electric cylinder 300, and improving the overall performance of the equipment and industrial production efficiency.

[0056] In one exemplary embodiment, controller 6 is a Googol GTC controller 6.

[0057] Among them, the specific models of the GTC controller 6 can be GTC-RC800 or GTC-NC610, etc.

[0058] In this embodiment, the Googol GTC controller (specific models such as GTC-RC800 or GTC-NC610) is selected because it possesses high stability and reliability, enabling long-term stable operation in complex industrial environments and ensuring uninterrupted precise control of the electric cylinder's lubrication operation. Secondly, its built-in timing and logic judgment functions accurately monitor the electric cylinder's operating time and determine the lubrication timing based on preset rules, achieving precise lubrication and effectively preventing over- or under-lubrication. Furthermore, these controllers often exhibit good compatibility, easily integrating with other equipment and systems, facilitating automated control of the entire industrial production process.

[0059] In one exemplary embodiment, the electric cylinder oil injection device also includes a human-machine interface device. The human-machine interface device is connected to the controller 6.

[0060] In this embodiment, operators can intuitively view key information such as the working time of the electric cylinder, the oiling status, and the remaining oil level in the oil tank through a human-machine interface device, allowing them to monitor the equipment's operation in real time and promptly detect and address any anomalies. Simultaneously, the human-machine interface device enables convenient parameter settings for the controller, such as adjusting the oiling timing, making the oiling operation more aligned with actual production needs. This significantly improves the flexibility and convenience of equipment use, optimizes the control of the entire oiling process, thereby enhancing overall equipment operating efficiency, ensuring the smooth and orderly operation of industrial production, and reducing the risk of equipment failure due to inconvenient operation or unreasonable parameter settings.

[0061] In one exemplary embodiment, the human-computer interaction device is a Googol GRP4000 teach pendant.

[0062] In this embodiment, the Googol GRP4000 teach pendant features a simple, intuitive, and user-friendly interface, allowing operators to quickly familiarize themselves with the operating procedures and easily view various operating parameters and real-time status of the electric cylinder lubrication equipment, such as electric cylinder working time, lubrication frequency, and oil tank volume, thus accurately controlling the equipment. Simultaneously, it possesses precise parameter setting functions, allowing for convenient and detailed adjustments to key control parameters such as lubrication timing and mode, enabling lubrication operations to better adapt to diverse industrial production scenarios. Furthermore, the Googol GRP4000 teach pendant seamlessly integrates with devices such as the Googol GTC controller, ensuring efficient and accurate data transmission. Overall, this further enhances the ease of equipment operation, the precision of lubrication control, and the efficiency and reliability of the entire industrial production process.

[0063] In an exemplary embodiment, where the oil filling assembly 2 includes an oil tank 22, the device further includes a level sensor. The level sensor is used to detect the remaining oil level in the oil tank 22, and the level sensor is connected to a human-machine interface device via a controller 6.

[0064] For example, after the equipment starts up and operates normally, the level sensor begins to work. Installed at a suitable location inside the oil tank 22 of the oil filling assembly 2, it monitors the lubricating oil level in the oil tank 22 in real time using a corresponding sensing principle (such as ultrasonic, float, etc., depending on the specific level sensor type) to determine the remaining oil level. The level sensor converts the detected oil level data into a corresponding electrical signal (e.g., analog or digital signal, depending on the sensor's output format) and then transmits this signal to the controller 6. Upon receiving the oil level signal from the level sensor, the controller 6 analyzes and processes it, converting the oil level information into a recognizable data format. Then, the controller 6 transmits this processed oil level data to a connected human-machine interface device (such as a Googol GRP4000 teach pendant). After receiving the data, the human-machine interface device displays the remaining oil level in the oil tank 22 in an intuitive way (such as numerical display, level progress bar, etc.) on its display interface, allowing operators to check at any time. Based on the displayed remaining oil level information, operators can prepare in advance and promptly replenish lubricating oil when the oil level approaches the lower limit. This ensures that the oil injection component 2 continuously and accurately injects oil into the electric cylinder 300 when there is sufficient lubricating oil in the oil tank 22, maintaining good lubrication of the electric cylinder 300 and stable operation of the entire equipment. It also avoids problems such as interruption of oil injection or affecting the normal operation of the electric cylinder 300 due to lack of oil.

[0065] In this embodiment, the liquid level sensor can detect the remaining oil level in the oil tank in real time and accurately. This data is transmitted to the controller, processed, and then fed back to the human-machine interface for intuitive display. Operators can clearly know the oil reserve status at any time. This allows for advance prediction of whether lubricating oil needs to be added, avoiding interruptions in lubrication due to insufficient oil in the tank, and also helps to rationally plan the timing of lubricating oil addition, achieving refined equipment operation and maintenance management. At the same time, this real-time monitoring and display mechanism further improves the reliability and stability of the entire electric cylinder lubrication equipment, ensuring continuous and efficient industrial production and reducing the risk of equipment failure due to oil level issues.

[0066] In one exemplary embodiment, this application also provides an oil injection control system for an electric cylinder 300, the system comprising: an electric cylinder 300 and the electric cylinder oil injection device described in the above embodiment.
