During the production process, the oil supply of the robot (for example, lubrication of the guide rails and rack mechanisms in the robot) will directly affect the service life of the robot.

[0003] At present, the related technology usually adopts manual refueling to supply oil to the robot, which is prone to problems such as oil leakage or untimely refueling, thereby shortening the service life of the robot. Summary of the invention

At the same time, the injection molding machine can turn off the oil pump and stop supplying oil to the manipulator based on the manipulator oil supply shutdown signal sent by the manipulator.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0013] At present, the robot and injection molding machine usually use two independent oil supply systems, which are costly. In addition, the oil supply system of the robot usually adopts a hand-cranked oiling device, which requires manual oiling from time to time. This manual oiling method will bring about problems such as large randomness and easy to forget to oil for a long time, which will cause the mechanical structures such as the linear rail and rack of the robot to wear, thereby shortening the service life of the robot.

[0014] The oil supply method provided in the embodiment of the present application can automatically supply oil to the injection molding machine and the manipulator through the injection molding machine, without the need to set up two independent oil supply systems for the injection molding machine and the manipulator, thereby reducing costs. In addition, this automated method of supplying oil to the injection molding machine and the manipulator also solves the problems of large randomness, easy omission or untimely oil supply in the manual oil supply method, and also avoids the problem of shortening the service life of the manipulator due to omission or untimely oil supply.

[0016] In one embodiment of the present application, the oil supply pipeline control component 400 has a first state and a second state; when the oil supply pipeline control component 400 is in the first state, the oil pump 300 is connected to the first oil supply pipeline 210 via the oil supply pipeline control component 400; when the oil supply pipeline control component 400 is in the second state, the oil pump 300 is connected to the second oil supply pipeline 220 via the oil supply pipeline control component 400. The oil supply pipeline control component 400 may be in the first state by default.

[0017] In one embodiment of the present application, the oil supply device 100 may further include a first pressure detection element, which is disposed in the first oil supply pipeline 210. In one embodiment of the present application, the oil supply device 100 may further include a second pressure detection element, which is disposed in the second oil supply pipeline 220. Wherein, both the first pressure detection element and the second pressure detection element may be hydraulic pressure switches. In an embodiment of the present application, the injection molding machine may include an injection molding machine body and a first controller; the manipulator may include a manipulator body and a second controller, and the first controller is different from the second controller. The oil storage device 200 may be a lubricating oil tank; the oil pump 300 may be a lubricating oil pump.

[0018] Please refer to Figure 2 , Figure 2: is a flow chart of a fuel supply method provided in an embodiment of the present application. Figure 2 As shown, the oil supply method provided in the embodiment of the present application includes: Step 110, the injection molding machine obtains a manipulator oil supply start signal from the manipulator; In the embodiment of the present application, the manipulator oil supply start signal can be used to indicate that the manipulator has an oil supply demand. When the manipulator has an oil supply demand, the manipulator can transmit the manipulator oil supply start signal to the injection molding machine. When the injection molding machine receives the manipulator oil supply start signal, it can further control the oil pump and the oil supply pipeline control component to supply oil to the manipulator to meet the manipulator's oil supply demand.

[0019] Step 120, the injection molding machine controls the oil pump to start in response to the oil supply start signal of the manipulator, and controls the oil supply pipeline control component to send the oil delivered by the oil pump to the manipulator via the second oil supply pipeline, wherein the oil pump is connected to the oil supply pipeline control component, the oil supply pipeline control component is connected to the injection molding machine via the first oil supply pipeline, and the oil supply pipeline control component is connected to the manipulator via the second oil supply pipeline; In an embodiment of the present application, the oil pump may be connected to an oil storage device, and the oil storage device may be an oil storage tank. The oil stored in the oil storage device may be lubricating oil, and lubricating oil is used as an example for discussion below. The injection molding machine may be connected to the oil pump and the oil supply pipeline control component respectively. After the injection molding machine receives the manipulator oil supply start signal, in response to the manipulator start signal, the injection molding machine may transmit an oil pump start instruction to the oil pump to start the oil pump, so that the oil pump pumps out lubricating oil from the oil storage device. In addition, the injection molding machine may control the oil supply pipeline control component to be connected to the second oil supply pipeline, so that the lubricating oil pumped out by the oil pump is sent to the manipulator via the second oil supply pipeline to achieve lubrication of the manipulator.

[0020] In one embodiment of the present application, the oil supply pipeline control component has a first state and a second state; the first state and the second state of the oil supply pipeline control component are both controlled by the injection molding machine; when the oil supply pipeline control component is in the first state, the oil pump is connected to the first oil supply pipeline via the oil supply pipeline control component; when the oil supply pipeline control component is in the second state, the oil pump is connected to the second oil supply pipeline via the oil supply pipeline control component.

[0021] In the embodiment of the present application, the oil supply pipeline control component can be connected to one of the first oil supply pipeline and the second oil supply pipeline at the same time, so as to provide lubricating oil to one of the injection molding machine and the manipulator. It can be determined whether to provide lubricating oil to the injection molding machine or the manipulator by the state of the oil supply pipeline control component. The injection molding machine can transmit a control signal to the oil supply pipeline control component, and the control signal causes the oil supply pipeline control component to be in one of the first state or the second state.

[0022] Specifically, the oil supply pipeline control component may be in any one of the first state and the second state by default, and the control signal may be an oil supply pipeline switching signal. After receiving the oil supply pipeline switching signal, the oil supply pipeline control component may switch from the default state to another state based on the oil supply pipeline switching signal.

[0023] When the oil supply pipeline control component is in the first state, the oil pump can be connected to the first oil supply pipeline via the oil supply pipeline control component, and the lubricating oil pumped out by the oil pump can be sent to the injection molding machine via the oil supply main pipeline of the oil pump and the first oil supply pipeline, thereby achieving the purpose of lubricating the injection molding machine. When the oil supply pipeline control component is in the second state, the oil pump can be connected to the second oil supply pipeline via the oil supply pipeline control component, and the lubricating oil pumped out by the oil pump can be sent to the manipulator via the oil supply main pipeline of the oil pump and the second oil supply pipeline, thereby achieving the purpose of lubricating the manipulator.

[0024] In one embodiment of the present application, the oil supply pipeline control component is in the first state by default.

[0025] In the embodiment of the present application, since the frequency of adding lubricating oil to the injection molding machine is higher in actual application, the oil supply pipeline control component can be in the first state by default. In this way, when the oil supply pipeline control component is in the default state, lubrication of the injection molding machine can be achieved.

[0026] In one embodiment of the present application, the oil supply pipeline control component may be a directional control valve.

[0027] In the embodiment of the present application, the directional control valve is used to control the flow direction of the lubricating oil pumped out by the oil pump. Figure 3-1 The outlet of the oil pump oil supply main pipeline is marked as P, the inlet of the first oil supply pipeline is marked as A, and the inlet of the second oil supply pipeline is B. The flow direction of the lubricating oil can be from P to A, or from P to B, and the directional control valve can be used to control the flow direction of the lubricating oil.

[0028] Exemplarily, in one embodiment of the present application, the directional control valve may include a solenoid valve.

[0029] In an embodiment of the present application, the solenoid valve may include an electromagnet and a valve core, and the flow direction of the lubricating oil pumped out by the oil pump may be controlled by the electromagnet and the valve core being attracted. Specifically, when the solenoid valve is energized, the electromagnet and the valve core in the solenoid valve may be attracted. When the solenoid valve is not energized, that is, the electromagnet and the valve core are not attracted, the oil supply pipeline control component may be in a first state, and the oil pump may be connected to the first oil supply pipeline via the oil supply pipeline control component. When the solenoid valve is energized, that is, the electromagnet and the valve core are attracted, the oil supply pipeline control component may be in a second state, and the oil pump may be connected to the second oil supply pipeline via the oil supply pipeline control component.

[0030] Specifically, please refer to Figure 3-1 and Figure 3-2 , Figure 3-1 is a schematic diagram of an oil supply pipeline control component provided by an embodiment of the present application in a first state, Figure 3-2 Schematic diagram of a fuel supply pipeline control component in a second state provided by an embodiment of the present application. Figure 3-1 As shown, M, N, K and T are valve ports in the oil supply pipeline control component 400, N port is connected to the oil supply main pipeline of the oil pump 300, M port is connected to the first oil supply pipeline 210, K port is connected to the second oil supply pipeline 220, T port is blocked, a is a magnet, and b is a spring. When the oil supply pipeline control component 400 is not powered, the flow direction of the lubricating oil can be from the outlet P of the oil pump oil supply main pipeline to the inlet A of the first oil supply pipeline. The oil supply pipeline control component 400 is in the first state, and M, N, K and T ports are as shown in FIG. Figure 3-1 As shown. The middle position function of the oil supply pipeline control component 400 is N to M, K to T. At this time, the oil pump 300 provides lubricating oil to the injection molding machine 500 through port A when working. When the oil supply pipeline component 400 is powered on, the flow direction of the lubricating oil can be from the outlet P of the oil pump oil supply main pipeline to the inlet B of the second oil supply pipeline. The oil supply pipeline control component 400 is in the second state, and the M, N, K and T ports are as shown in FIG. Figure 3-2 As shown, at this time, the oil pump 300 provides lubricating oil to the manipulator 600 through the B port when working. It should be understood that Figure 3-1 and Figure 3-2 The oil pump 300 may be connected to the motor 310 , and the oil pump 300 may also be connected to the oil storage device via the filter device 320 , wherein the filter device 320 may be used to filter some impurities, and the filter device 320 is an optional component.

[0031] Step 130, the injection molding machine receives a manipulator oil supply closing signal sent by the manipulator; In the embodiment of the present application, after the robot completes lubrication, a robot oil supply shutoff signal may be fed back to the injection molding machine, and the robot oil supply shutoff signal may be used to instruct to stop supplying oil to the robot.

[0032] In one embodiment of the present application, before the injection molding machine receives the manipulator oil supply shutdown signal sent by the manipulator, the manipulator may receive a manipulator oil supply completion signal transmitted by a second pressure detection element, and the second pressure detection element may be arranged on the second oil supply pipeline; the manipulator sends a manipulator oil supply shutdown signal to the injection molding machine in response to the manipulator oil supply completion signal.

[0033] In the embodiment of the present application, in order to realize the automatic lubrication of the manipulator, a second pressure detection element may be provided on the second oil supply pipeline, and the second pressure detection element may be used to detect the liquid pressure of the lubricating oil on the second oil supply pipeline. When the liquid pressure detected by the second pressure detection element is greater than or equal to the preset liquid pressure value (second set value), the second pressure detection element may feedback a manipulator oil supply completion signal to the manipulator. After the manipulator receives the manipulator oil supply completion signal, a manipulator oil supply closing signal may be transmitted to the injection molding machine.

[0034] After the injection molding machine receives the oil supply shutdown signal of the robot, the oil supply pipeline control component can be controlled to no longer connect to the second oil supply pipeline, and stop supplying lubricating oil to the robot. This can automatically stop supplying lubricating oil to the robot after the lubricating oil supplied to the robot meets the standard, avoiding the situation of insufficient or excessive lubricating oil, and can further realize the automatic supply of lubricating oil to the robot.

[0035] In one embodiment of the present application, the second pressure detection element may be a second hydraulic pressure switch, and the manipulator oil supply completion signal is generated after the pressure detected by the second hydraulic pressure switch reaches a second set value.

[0036] In the embodiment of the present application, the second hydraulic pressure switch may be in a closed state by default, and when the detected liquid pressure exceeds a preset value, the second hydraulic pressure switch may be in an open state. When the second hydraulic pressure switch is in an open state, the second hydraulic pressure switch may generate a manipulator oil supply completion signal, and feed back the manipulator oil supply completion signal to the manipulator. After receiving the manipulator oil supply completion signal, the manipulator may transmit a manipulator oil supply closing signal to the injection molding machine.

[0037] Step 140, the injection molding machine controls the oil pump to be turned off in response to the oil supply shut-off signal of the robot; In an embodiment of the present application, after the injection molding machine receives the robot oil supply shutdown signal fed back by the robot, it can respond to the robot oil supply shutdown signal and issue an oil pump shutdown command to the oil pump to control the oil pump to shut down, and no longer add mechanical oil to the robot to avoid waste caused by excessive oil addition.

[0038] In one embodiment of the present application, the injection molding machine includes an injection molding machine body and a first controller, the manipulator includes a manipulator body and a second controller, and the oil supply control parameters of the first controller and the oil supply control parameters of the second controller are set separately.

[0039] In the embodiment of the present application, the injection molding machine body includes a body in the injection molding machine that has a lubrication requirement, and the first controller can be used to process signals received by the injection molding machine, such as the injection molding machine oil supply completion signal, the robot oil supply shutdown signal, and the robot oil supply start signal mentioned above. The robot body is a body in the robot that has a lubrication requirement, and the second controller can be used to process signals received by the robot, such as the robot oil supply completion signal.

[0040] Considering that the injection molding machine and the manipulator may have different oil supply control parameters during the oil supply process, the oil supply control parameters of the injection molding machine and the oil supply control parameters of the manipulator can be set separately, that is, the oil supply control parameters of the injection molding machine and the oil supply control parameters of the manipulator can be independently set, managed and controlled.

[0041] In one embodiment of the present application, the oil pump is a lubricating oil pump, the oil supply control parameters of the first controller and the oil supply control parameters of the second controller both include lubrication control parameters, and the lubrication control parameters of the second controller include an adjustable automatic lubrication module.

[0042] In an embodiment of the present application, the lubricating oil pump can pump lubricating oil from an oil storage device such as a lubricating oil tank, and the injection molding machine and the manipulator can share the lubricating oil pump and the lubricating oil tank. During the installation of the lubricating oil tank and the lubricating oil pump, the lubricating oil tank and the lubricating oil pump can be installed at a lower position, as far away from the injection structure as possible. In this way, the process of adding lubricating oil can be made more convenient, and there is no risk of falling and scalding.

[0043] The oil supply control parameter of the first controller and the oil supply control parameter of the second controller may both include lubrication control parameters. Specifically, the lubrication control parameter of the first controller and the lubrication control parameter of the second controller may both include an adjustable automatic lubrication modulus, the automatic lubrication modulus of the injection molding machine is used to describe the interval modulus of the injection molding machine starting lubrication, and the automatic lubrication modulus of the manipulator is used to describe the interval modulus of the manipulator starting lubrication. For example, if the automatic lubrication modulus of the injection molding machine is 16, the lubrication process of the injection molding machine will be started every time the injection molding machine injects 16 molds.

[0044] In addition, taking the lubrication control parameters of the first controller as an example, it can also include the operating modulus of the injection molding machine, the modulus before the next lubrication, and the automatic lubrication alarm time. When the injection molding machine just starts lubrication, the operating modulus is 0, and the modulus before the next lubrication is equal to the automatic lubrication modulus of the injection molding machine. After executing a cycle, the operating modulus is increased by 1, and the modulus before the next lubrication is reduced by 1. When the modulus before the next lubrication is 0, the injection molding machine lubrication start signal is output. After the lubrication of the injection molding machine is completed, the operating modulus is reset, and the modulus before the next lubrication is restored to the set value of the automatic lubrication modulus. After the injection molding machine is lubricated, if the injection molding machine oil supply completion signal fed back by the first pressure detection element is exceeded within the set automatic lubrication alarm time, the first controller can automatically alarm. If the injection molding machine oil supply completion signal fed back by the first pressure detection element is received within the set automatic lubrication alarm time, the current accumulated time will be reset to zero, and the timing will be restarted when the injection molding machine is lubricated next time.

[0045] Correspondingly, the lubrication control parameters of the second controller may also include the operating module of the manipulator, the module until the next lubrication, and the automatic lubrication alarm time. The automatic lubrication module and automatic lubrication alarm time of the manipulator are similar to those of the injection molding machine and will not be repeated here. In addition, the lubrication control parameters of the second controller may also include the idle lubrication time of the manipulator. After the manipulator is turned on, the current operating module of the manipulator is 0. The second controller can determine the time difference from the current time when the manipulator was last shut down based on its system time. If the time difference is greater than the idle lubrication time, the second controller can actively transmit the manipulator oil supply start signal to the injection molding machine and execute a lubrication action of the manipulator to avoid operating the manipulator in a situation where the manipulator is not lubricated enough after being idle for a long time. This situation may shorten the service life of the manipulator.

[0046] In an embodiment of the present application, the injection molding machine obtains a manipulator oil supply start signal from the manipulator; the injection molding machine controls the oil pump to start in response to the manipulator oil supply start signal, and controls the oil supply pipeline control component to send the oil delivered by the oil pump to the manipulator via the second oil supply pipeline; the injection molding machine receives a manipulator oil supply shutdown signal sent by the manipulator; the injection molding machine controls the oil pump to shut down in response to the manipulator oil supply shutdown signal; wherein, the oil pump is connected to the oil supply pipeline control component, the oil supply pipeline control component is connected to the injection molding machine via the first oil supply pipeline, and the oil supply pipeline control component is connected to the manipulator via the second oil supply pipeline. In this way, after the injection molding machine obtains the oil supply start signal of the robot, it can respond to the manipulator oil supply start signal, control the oil pump to start, and control the oil delivered by the oil pump to be sent to the manipulator via the second oil supply pipeline, thereby lubricating the manipulator. At the same time, the injection molding machine can turn off the oil pump and stop lubricating the manipulator based on the manipulator oil supply shutdown signal sent by the manipulator. In other words, the lubrication of the manipulator can be achieved through the injection molding machine. The entire process does not require human intervention and is not prone to oil leakage or untimely refueling, thereby solving the problem of shortening the service life of the manipulator by the method of using related technologies.

[0047] Please refer to Figure 4 , Figure 4 is a flow chart of another oil supply method provided in an embodiment of the present application. Figure 4 As shown, the oil supply method provided in the embodiment of the present application includes: Step 410: The injection molding machine obtains a manipulator oil supply start signal from the manipulator.

[0048] Step 420: the injection molding machine determines whether the injection molding machine oil supply start-up condition is met.

[0049] In an embodiment of the present application, the injection molding machine oil supply start condition may include at least one of the conditions that the oil pump can operate normally and the remaining oil amount is sufficient. The injection molding machine oil supply start condition may also include the arrival of the automatic lubrication modulus of the injection molding machine, and the manipulator oil supply start signal may be obtained when the automatic lubrication modulus of the manipulator arrives. Among them, the arrival of the automatic lubrication modulus of the injection molding machine is used to indicate that the current modulus from the last time the injection molding machine completed oil supply is equal to the automatic lubrication modulus of the injection molding machine, and the arrival of the automatic lubrication modulus of the manipulator is used to indicate that the current modulus from the last time the manipulator completed oil supply is equal to the automatic lubrication modulus of the manipulator. In other words, the arrival of the automatic lubrication modulus of the injection molding machine means starting a new round of oil supply for the injection molding machine.

[0050] In one embodiment of the present application, when the injection molding machine determines that the injection molding machine oil supply start-up conditions are met, the injection molding machine controls the oil pump to start, and controls the oil supply pipeline control component to send the oil delivered by the oil pump to the injection molding machine via the first oil supply pipeline.

[0051] In the embodiment of the present application, in actual situations, compared with the lubrication action of the manipulator, the lubrication action of the injection molding machine is more frequent, and the lubrication priority of the injection molding machine can be set higher than the lubrication priority of the manipulator. That is to say, when the automatic lubrication modulus of the injection molding machine and the automatic lubrication modulus of the manipulator arrive at the same time, the injection molding machine can be supplied with oil first, and then the manipulator can be supplied with oil after the injection molding machine is supplied with oil. Therefore, when it is determined that the injection molding machine oil supply start-up conditions are met, the injection molding machine can control the oil pump to start, and control the oil supply pipeline control component to connect to the first oil supply pipeline, so that the lubricating oil pumped out by the oil pump is sent to the injection molding machine via the first oil supply pipeline to achieve lubrication of the injection molding machine.

[0052] In one embodiment of the present application, after the injection molding machine controls the oil pump to turn on, and controls the oil pipeline control component to send the oil delivered by the oil pump to the injection molding machine via the first oil supply pipeline, the injection molding machine can receive an injection molding machine oil supply completion signal transmitted by a first pressure detection element, and the first pressure detection element can be set in the first oil supply pipeline; the injection molding machine can control the oil pump to turn off in response to the injection molding machine oil supply completion signal.

[0053] In the embodiment of the present application, in order to realize automatic lubrication of the injection molding machine, a first pressure detection element may be provided on the first oil supply pipeline that provides lubricating oil to the injection molding machine, and the first pressure detection element is used to detect the liquid pressure on the first oil supply pipeline. When the liquid pressure detected by the first pressure detection element is greater than or equal to the preset liquid pressure value, the first pressure detection element may feed back a signal that the injection molding machine oil supply is completed to the injection molding machine.

[0054] After the injection molding machine receives the injection molding machine oil supply completion signal, the oil supply pipeline control component can be controlled to no longer connect to the first oil supply pipeline, and stop supplying lubricating oil to the injection molding machine. Thereby, after the lubricating oil supplied to the injection molding machine meets the standard, the supply of lubricating oil to the injection molding machine is automatically stopped, avoiding the situation of insufficient or excessive lubricating oil, and further realizing the automatic supply of lubricating oil to the injection molding machine.

[0055] In one embodiment of the present application, the first pressure detection element is a first hydraulic pressure switch, and the injection molding machine oil supply completion signal is generated after the pressure detected by the first hydraulic pressure switch reaches a first set value.

[0056] In the embodiment of the present application, the first hydraulic pressure switch may be in a closed state by default, and when the detected liquid pressure exceeds a preset value, the first hydraulic pressure switch may be in an open state. When the first hydraulic pressure switch is in an open state, the first hydraulic pressure switch may feed back a signal indicating that the injection molding machine is supplied with oil, to the injection molding machine.

[0057] Step 430, when the injection molding machine determines that the injection molding machine oil supply start condition is not met, the injection molding machine responds to the manipulator oil supply start signal, controls the oil pump to start, and controls the oil supply pipeline control component to send the oil delivered by the oil pump to the manipulator via the second oil supply pipeline.

[0058] In an embodiment of the present application, when there is no need to supply oil to the injection molding machine, the robot oil supply start signal can be immediately responded to, the oil pump can be controlled to start, and the oil supply pipeline control component can be controlled to connect to the second oil supply pipeline. The oil pumped out by the oil pump can be sent to the robot via the second oil supply pipeline.

[0059] Please refer to Figure 5 , Figure 5 This is a general concept diagram of an oil supply method provided in an embodiment of the present application. Figure 5 As shown, the automatic lubrication system includes an oil pump and a first pressure detection element. The oil pump and the oil supply pipeline control component can be controlled by the first controller in the injection molding machine. The first controller in the injection molding machine can transmit the oil pump start instruction to the oil pump. The automatic lubrication system can complete the automatic lubrication of the injection molding machine through the oil pump and the first pressure detection element. The first controller can receive the injection molding machine oil supply completion signal fed back by the first pressure detection element. When the second controller of the manipulator determines that the automatic lubrication modulus of the manipulator has arrived, the second controller of the manipulator can transmit the manipulator lubrication start signal to the first controller in the injection molding machine through the input / output (I / O) interface or other communication methods. After receiving the manipulator lubrication start signal, the first controller can transmit the oil supply pipeline switching signal to the oil supply pipeline control component, so that the lubricating oil pumped out by the oil pump lubricates the manipulator, and the automatic lubrication of the manipulator can be completed through the second pressure detection element on the second oil supply pipeline. The second controller can receive the manipulator oil supply completion signal fed back by the second pressure detection element.

[0060] When the automatic lubrication modulus of the injection molding machine and the automatic lubrication modulus of the manipulator arrive at the same time, the injection molding machine can be lubricated first, and then the manipulator can be lubricated. Specifically, after the first controller receives the manipulator oil supply start signal, it can first determine whether the automatic lubrication modulus of the injection molding machine has arrived. When the automatic lubrication modulus of the injection molding machine has not arrived, the injection molding machine can issue an oil pump start command to the oil pump, and at the same time transmit the oil supply pipeline switching signal to the oil supply pipeline control component, and the oil pump lubricates the manipulator at this time. When the automatic lubrication modulus of the injection molding machine arrives, the oil pump lubricates the injection molding machine first, and after the lubrication of the injection molding machine is completed, the manipulator is lubricated.

[0061] When the oil pump lubricates the injection molding machine or robot, the automatic lubrication timing, automatic lubrication delay and automatic lubrication times of the oil pump can be automatically recorded. The automatic lubrication timing is the single working time of the oil pump, and the automatic lubrication delay is the time to wait for the next oil pump to start after the oil pump stops working. At this time, the lubricating oil can be pressed into the lubrication pipeline through the distributor. The automatic lubrication times are the number of times the oil pump executes the "automatic lubrication timing" and "automatic lubrication delay" in one lubrication cycle.

[0062] Step 440: the injection molding machine receives a manipulator oil supply closing signal sent by the manipulator.

[0063] Step 450, the injection molding machine controls the oil pump to shut down in response to the oil supply shutdown signal of the robot; wherein the oil pump is connected to the oil supply pipeline control component, the oil supply pipeline control component is connected to the injection molding machine via the first oil supply pipeline, and the oil supply pipeline control component is connected to the robot via the second oil supply pipeline.

[0064] The relevant contents of step 440 to step 450 may refer to the previous discussion.

[0065] In the embodiment of the present application, by judging the oil supply start-up conditions of the injection molding machine and combining the switching of the oil supply pipeline control components, time-sharing oil supply to the injection molding machine and the robot can be achieved. When the oil supply start-up conditions of the injection molding machine are met, the injection molding machine can be supplied with oil first by controlling the oil supply pipeline control components. In this way, the injection molding machine and the robot share the same oil supply system, reducing the cost of supplying oil to the injection molding machine and the robot.

[0066] Figure 6 This is a specific flow chart of a fuel supply method provided in an embodiment of the present application. Figure 6 , the oil supply method provided in the embodiment of the present application includes: Step 605: The injection molding machine obtains a manipulator oil supply start signal from the manipulator.

[0067] In step 610, the injection molding machine may determine whether the injection molding machine oil supply start-up conditions are met. If the injection molding machine determines that the injection molding machine oil supply start-up conditions are met, the following steps 620-640 may be performed first to provide lubricating oil to the injection molding machine, and then the following steps 650-670 may be performed to provide lubricating oil to the manipulator. If the injection molding machine determines that the injection molding machine oil supply start-up conditions are not met, the following steps 650-670 may be directly performed to provide lubricating oil to the manipulator.

[0068] Step 620: the injection molding machine controls the oil pump to start, and controls the oil supply pipeline control component to deliver the oil delivered by the oil pump to the injection molding machine via the first oil supply pipeline.

[0069] In step 620, the oil supply pipeline control component has a first state and a second state, and the first state and the second state of the oil supply pipeline control component are both controlled by the injection molding machine. When the oil supply pipeline control component is in the first state, the oil pump is connected to the first oil supply pipeline via the oil supply pipeline control component; when the oil supply pipeline control component is in the second state, the oil pump is connected to the second oil supply pipeline via the oil supply pipeline control component. The oil supply pipeline control component is in the first state by default.

[0070] Step 630: the injection molding machine receives an injection molding machine oil supply completion signal transmitted by a first pressure detection element, where the first pressure detection element is disposed in the first oil supply pipeline.

[0071] The first pressure detection element in step 630 may be a first hydraulic pressure switch, and the injection molding machine oil supply completion signal is generated after the pressure detected by the first hydraulic pressure switch reaches a first set value.

[0072] Step 640: the injection molding machine controls the oil pump to be turned off in response to the injection molding machine oil supply completion signal.

[0073] Step 650 , the injection molding machine controls the oil pump to start in response to the oil supply start signal of the robot, and controls the oil supply pipeline control component to deliver the oil delivered by the oil pump to the robot via the second oil supply pipeline.

[0074] The injection molding machine includes an injection molding machine body and a first controller, the manipulator includes a manipulator body and a second controller, and the oil supply control parameters of the first controller and the oil supply control parameters of the second controller are set separately. The oil pump may be a lubricating oil pump, and the oil supply control parameters of the first controller and the oil supply control parameters of the second controller both include lubrication control parameters, and the lubrication control parameters of the second controller include an adjustable automatic lubrication modulus.

[0075] Step 660: the manipulator receives a manipulator oil supply completion signal transmitted by a second pressure detection element, and the second pressure detection element is arranged in the second oil supply pipeline.

[0076] Step 670: the robot sends a robot oil supply closing signal to the injection molding machine in response to the robot oil supply completion signal.

[0077] Step 680: the injection molding machine receives a manipulator oil supply closing signal sent by the manipulator.

[0078] Step 690, the injection molding machine controls the oil pump to shut down in response to the oil supply shutdown signal of the robot; wherein the oil pump is connected to the oil supply pipeline control component, the oil supply pipeline control component is connected to the injection molding machine via the first oil supply pipeline, and the oil supply pipeline control component is connected to the robot via the second oil supply pipeline.

[0079] In the embodiment of the present application, the automatic lubrication of the injection molding machine and the manipulator can be realized by the method described in the above steps 605 to 690. Figure 7 The control process for achieving automatic lubrication is further described.

[0080] Please refer to Figure 7 , Figure 7 1 is a flow chart of a control process for realizing automatic lubrication provided by an embodiment of the present application. Figure 7 As shown, lubrication control parameters (such as automatic lubrication modulus) can be set in the first controller of the injection molding machine and the second controller of the manipulator, respectively. When the second controller of the manipulator determines that the automatic lubrication modulus of the manipulator has been reached, the second controller can send a manipulator oil supply start signal to the injection molding machine. After the injection molding machine receives the manipulator oil supply start signal, the first controller of the injection molding machine can first determine whether the automatic lubrication modulus of the injection molding machine has been reached.

[0081] Among them, the automatic lubrication modulus of the injection molding machine reaches the value that the modulus of the injection molding machine from the last oil supply is equal to the automatic lubrication modulus of the injection molding machine, and the automatic lubrication modulus of the manipulator reaches the value that the modulus of the manipulator from the last oil supply is equal to the automatic lubrication modulus of the manipulator. In other words, the automatic lubrication modulus of the injection molding machine reaches the value that a new round of oil supply of the injection molding machine is started.

[0082] When it is determined that the automatic lubrication modulus of the injection molding machine has been reached, an oil pump start instruction can be transmitted to the oil pump to control the oil pump to start, and at the same time, the oil supply pipeline control component is not energized, so that the oil supply pipeline control component is in the first state, the oil pump is connected to the first oil supply pipeline, and the lubricating oil pumped out by the oil pump is sent to the injection molding machine via the first oil supply pipeline to add lubricating oil to the injection molding machine. The first pressure detection element set on the first oil supply pipeline can detect the lubricating oil hydraulic pressure on the first oil supply pipeline. When the first pressure detection element determines that the detected hydraulic pressure is greater than the first set value, it can be determined that the addition of lubricating oil to the injection molding machine is completed, and an injection molding machine oil supply completion signal is generated.

[0083] At this time, a signal indicating that the injection molding machine oil supply is completed can be sent to the injection molding machine. At the same time, the injection molding machine can transmit an oil pump start instruction to the oil pump to control the oil pump to start, and energize the oil supply pipeline control component so that the oil supply pipeline control component is in the second state, switching from supplying oil to the injection molding machine to supplying oil to the manipulator. The oil pump is connected to the second oil supply pipeline, and the lubricating oil pumped out by the oil pump is sent to the manipulator via the second oil supply pipeline to add lubricating oil to the manipulator. The second pressure detection element provided on the second oil supply pipeline can detect the lubricating oil hydraulic pressure on the second oil supply pipeline. When the second pressure detection element determines that the detected hydraulic pressure is greater than the second set value, it can be determined that the addition of lubricating oil to the manipulator is completed, and a signal indicating that the manipulator oil supply is completed is generated.

[0084] When it is determined that the automatic lubrication modulus of the injection molding machine has not been reached, lubricating oil can be added to the manipulator immediately. That is, the injection molding machine can transmit an oil pump start instruction to the oil pump to control the oil pump to start, and energize the oil supply pipeline control component to put the oil supply pipeline control component in the second state, and start the process of adding lubricating oil to the manipulator. The specific process can refer to the above introduction and will not be expanded here.

[0085] After the injection molding machine receives the injection molding machine oil supply completion signal or the manipulator oil supply completion signal, the injection molding machine can transmit an oil pump closing instruction to the oil pump and simultaneously transmit an oil supply pipeline switching closing instruction to the oil supply pipeline control component, so that the oil supply pipeline control component is in the first state. At the same time, the oil supply process of the injection molding machine and the manipulator is ended.

[0086] like Figure 3-1 and Figure 3-2 As shown, the pressure judgment of the oil supply pipeline in the above control process is completed by two pressure switches, namely Figure 3-1 or Figure 3-2The first pressure detection element 700 and the second pressure detection element 800 in the injection molding machine are provided. Taking the second pressure detection element as an example, when the detected hydraulic pressure is greater than the second set value, the second pressure detection element can be closed, and at the same time, a manipulator oil supply completion signal is transmitted to the second controller of the manipulator. After receiving the manipulator oil supply completion signal, the second controller of the manipulator can transmit a manipulator oil supply shutdown signal to the first controller of the injection molding machine through an I / O interface or other communication methods. After receiving the manipulator oil supply shutdown signal, the first controller of the injection molding machine can issue an oil pump shutdown instruction to the oil pump. In this process, if the manipulator oil supply shutdown signal is not detected after the automatic lubrication alarm time has exceeded after the lubrication is started, the first controller of the injection molding machine can issue an alarm message for prompting.

[0087] In an embodiment of the present application, the injection molding machine obtains a manipulator oil supply start signal from the manipulator; the injection molding machine controls the oil pump to start in response to the manipulator oil supply start signal, and controls the oil supply pipeline control component to send the oil delivered by the oil pump to the manipulator via the second oil supply pipeline; the injection molding machine receives a manipulator oil supply shutdown signal sent by the manipulator; the injection molding machine controls the oil pump to shut down in response to the manipulator oil supply shutdown signal; wherein, the oil pump is connected to the oil supply pipeline control component, the oil supply pipeline control component is connected to the injection molding machine via the first oil supply pipeline, and the oil supply pipeline control component is connected to the manipulator via the second oil supply pipeline. In this way, after the injection molding machine obtains the oil supply start signal of the robot, it can respond to the manipulator oil supply start signal, control the oil pump to start, and control the oil delivered by the oil pump to be sent to the manipulator via the second oil supply pipeline, thereby lubricating the manipulator. At the same time, the injection molding machine can turn off the oil pump and stop lubricating the manipulator based on the manipulator oil supply shutdown signal sent by the manipulator. In other words, the lubrication of the manipulator can be achieved through the injection molding machine. The entire process does not require human intervention and is not prone to oil leakage or untimely refueling, thereby solving the problem of shortening the service life of the manipulator by the method of using related technologies.

[0088] The oil supply method provided in the embodiment of the present application may also have the following beneficial effects: First, the lubrication of the manipulator in the related art is usually manually refueled, and this manual method of adding lubricating oil has uncertainty. The present application automatically starts and completes the lubrication of the manipulator by setting the number of operations (automatic lubrication modulus), which can effectively solve the problem of missing lubricating oil or untimely lubrication. Second, the lubrication of the manipulator can be automatically stopped based on the hydraulic pressure switch when the lubrication of the manipulator is completed, which can avoid the problem of over- or under-lubrication, and at the same time, it can warn of the problems such as insufficient oil in the lubricating oil tank, too short lubrication time, and oil leakage in the lubrication pipeline. Third, the injection molding machine and the manipulator can share the lubricating oil supply system of the injection molding machine, which can effectively save costs. Fourth, the lubrication pipeline of the injection molding machine is set separately from the lubrication pipeline of the manipulator, and the lubrication control parameters of the injection molding machine and the manipulator are set separately to avoid problems that may occur when the lubrication start-up operation modulus settings of the two are inconsistent. Fifth, the oil pump and oil tank of the injection molding machine can be installed at a lower position, away from the injection structure, making refueling more convenient, while reducing the risk of falling and scalding. Sixth, after the robot has been idle for a long time, automatic lubrication can be performed when the robot is turned on.
