[0022] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0023] At present, the robot and the injection molding machine usually use two independent oil supply systems, which have high cost. Moreover, the oil supply system of the robot usually adopts a hand-operated oiling device, which needs manual and irregular manual oiling. This manual oiling method can bring problems such as randomness, easy to forget oiling for a long time, etc., which can cause wear of the linear rail, rack and other mechanical structures of the robot, thereby shortening the service life of the robot.

[0024] The oil supply device provided by the embodiment of the present application can be shared by the injection molding machine and the mechanical arm, thereby reducing the cost required for supplying oil to the mechanical arm. The oil supply device can automatically supply oil to the injection molding machine and the mechanical arm at different times through the oil supply pipeline control component, thereby solving the problems of randomness, easy missing or untimely oiling in manual oil supply to the mechanical arm.

[0025] Figure 1 FIG. 1 is a schematic diagram of an oil supply device provided by an embodiment of the present application. Referring to FIG. 1, Figure 1 the oil supply device 100 provided by the embodiment of the present application comprises an oil storage device 200, an oil pump 300, an oil supply pipeline control component 400, an injection molding machine 500 and a mechanical arm 600. The oil storage device 200 is in communication with the oil pump 300. The oil pump 300 is in communication with the oil supply pipeline control component 400. The oil supply pipeline control component 400 is in communication with the injection molding machine 500 via a first oil supply pipeline 110. The oil supply pipeline control component 400 is in communication with the mechanical arm 600 via a second oil supply pipeline. The mechanical arm 600 is connected to the injection molding machine 500. The injection molding machine 500 is connected to the oil pump 300 and the oil supply pipeline control component 400.

[0026] In the embodiment of the present application, the oil storage device is used to store oil (hereinafter, the lubricating oil is taken as an example for illustration). The oil pump is in communication with the oil storage device, and the oil pump can pump out the lubricating oil stored in the oil storage device. The oil pump is in communication with the oil supply pipeline control component via an oil supply main pipeline. The oil supply pipeline control component is used to control the connection of the first oil supply pipeline and the second oil supply pipeline. When the oil supply pipeline control component is in communication with the first oil supply pipeline, the oil supply main pipeline can be in communication with the first oil supply pipeline via the oil supply pipeline control component, and then the lubricating oil in the oil supply main pipeline can be sent to the injection molding machine via the first oil supply pipeline to provide the lubricating oil for the injection molding machine.

[0027] When the oil supply pipeline control component is in communication with the second oil supply pipeline, the oil supply main pipeline can be in communication with the second oil supply pipeline via the oil supply pipeline control component, and then the lubricating oil in the oil supply main pipeline can be sent to the mechanical arm via the second oil supply pipeline to provide the lubricating oil for the mechanical arm.

[0028] As shown in FIG. 1, Figure 1 the mechanical arm 600 is connected to the injection molding machine 500. The mechanical arm 600 can transmit a mechanical arm oil supply start signal to the injection molding machine 500. After receiving the mechanical arm oil supply start signal, the injection molding machine can control the oil supply pipeline control component 400 to be in communication with the second oil supply pipeline 120, thereby providing the lubricating oil for the mechanical arm.

[0029] In addition, the injection molding machine 500 is connected with the oil pump 300 and the oil supply pipeline control component 400 respectively, and the connection can be wired connection. The injection molding machine 500 can transmit an oil pump starting instruction to the oil pump 300 to start the oil pump 300 to pump out lubricating oil from the oil storage device 200. The injection molding machine 500 can transmit a control signal to the oil supply pipeline control component 400 to control the oil supply pipeline control component to be connected to the first oil supply pipeline or the second oil supply pipeline.

[0030] Specifically, in an embodiment of the present application, the oil supply pipeline control component has a first state and a second state; in the first state, the oil pump is connected to the first oil supply pipeline via the oil supply pipeline control component; in the second state, the oil pump is connected to the second oil supply pipeline via the oil supply pipeline control component.

[0031] In an 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 robot. Whether the lubricating oil is provided to the injection molding machine or the robot can be determined 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.

[0032] In the embodiment, the oil supply pipeline control component can be in any one of the first state and the second state by default, the control signal can be an oil supply pipeline switching signal, and the oil supply pipeline control component can switch from one state to another state based on the oil supply pipeline switching signal after receiving the oil supply pipeline switching signal.

[0033] 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 main oil supply pipeline and the first oil supply pipeline, so as to lubricate 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 robot via the main oil supply pipeline and the second oil supply pipeline, so as to lubricate the robot.

[0034] In an embodiment of the present application, the oil supply pipeline control component is in the first state by default.

[0035] In the embodiment of the present application, the oil supply pipeline control component can be in the first state by default, because the frequency of adding lubricating oil to the injection molding machine is higher in actual application. In this way, the lubrication of the injection molding machine can be conveniently realized when the oil supply pipeline control component is in the default state.

[0036] In an embodiment of the present application, the oil supply pipeline control component can be a directional control valve.

[0037] In the embodiment of the present application, the directional control valve is used to control the flow direction of the lubricating oil pumped by the oil pump. For example, referring to Figure 7 , the outlet of the oil supply main pipeline of the oil pump 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 marked as 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 which flow direction of the lubricating oil.

[0038] For example, in an embodiment of the present application, the directional control valve can include a solenoid valve.

[0039] In the embodiment of the present application, the solenoid valve can include an electromagnet and a valve core, and the flow direction of the lubricating oil pumped by the oil pump can be controlled by the attraction of the electromagnet and the valve core. Specifically, when the solenoid valve is powered on, the electromagnet and the valve core in the solenoid valve can be attracted. When the solenoid valve is not powered on, i.e. the electromagnet and the valve core are not attracted, the oil supply pipeline control component can be in the first state, and the oil pump can be connected to the first oil supply pipeline through the oil supply pipeline control component. When the solenoid valve is powered on, i.e. the electromagnet and the valve core are attracted, the oil supply pipeline control component can be in the second state, and the oil pump can be connected to the second oil supply pipeline through the oil supply pipeline control component.

[0040] In an embodiment of the present application, the oil storage device can be a lubricating oil tank, and the oil pump can be a lubricating oil pump. The injection molding machine and the robot can share the lubricating oil tank and the lubricating oil pump, the lubricating oil in the lubricating oil tank can be pumped out through the lubricating oil pump, transmitted to the injection molding machine through the first oil supply pipeline, and transmitted to the robot through the second oil supply pipeline, thereby realizing the provision of lubricating oil to the injection molding machine and the robot.

[0041] In the embodiment of the present application, 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 more convenient, and there is no risk of falling and scalding.

[0042] The oil supply equipment provided in the embodiments of the present application comprises an oil storage device, an oil pump, an oil supply pipeline control component, an injection molding machine and a mechanical arm. The oil storage device is in communication with the oil pump, the oil pump is in communication with the oil supply pipeline control component, the oil supply pipeline control component is in communication with the injection molding machine through a first oil supply pipeline, the oil supply pipeline control component is in communication with the mechanical arm through a second oil supply pipeline, the mechanical arm is connected to the injection molding machine, and the injection molding machine is connected to the oil pump and the oil supply pipeline control component respectively. In this way, since the oil supply pipeline control component is in communication with the injection molding machine through the first oil supply pipeline and in communication with the mechanical arm through the second oil supply pipeline, and the oil supply pipeline control component is in communication with the oil pump, the oil supply pipeline control component can be used to supply oil to the injection molding machine and the mechanical arm, that is, the injection molding machine and the mechanical arm can share the oil supply pipeline control component, the oil pump and the oil storage device in the oil supply equipment. In this way, it is no longer necessary to provide two sets of oil pumps and oil storage devices for the mechanical arm and the injection molding machine, the oil supply cost is reduced, and the problem of high oil supply cost in the related art is solved.

[0043] On the basis of the above-mentioned embodiments, the oil supply equipment can further comprise a first pressure detection element arranged on the first oil supply pipeline. Figure 2 , Figure 2 is a schematic view of another oil supply equipment provided in the embodiments of the present application. As shown in Figure 2 , the oil supply equipment 100 provided in the embodiments of the present application comprises an oil storage device 200, an oil pump 300, an oil supply pipeline control component 400, an injection molding machine 500, a mechanical arm 600 and a first pressure detection element 700. The oil storage device 200 is in communication with the oil pump 300, the oil pump 300 is in communication with the oil supply pipeline control component 400, the oil supply pipeline control component 400 is in communication with the injection molding machine 500 through a first oil supply pipeline 110, the first pressure detection element 700 is arranged on the first oil supply pipeline 110, the oil supply pipeline control component 400 is in communication with the mechanical arm 600 through a second oil supply pipeline 120, the mechanical arm 500 is connected to the injection molding machine 600, and the injection molding machine 600 is connected to the oil pump 300 and the oil supply pipeline control component 400 respectively.

[0044] In the embodiments of the present application, in order to realize automatic lubrication of the injection molding machine, a first pressure detection element can be arranged on the first oil supply pipeline for supplying lubricating oil to the injection molding machine. The first pressure detection element is used to detect the liquid pressure on the first oil supply pipeline. In the case where the liquid pressure detected by the first pressure detection element is greater than or equal to a preset liquid pressure value, the first pressure detection element can feed back an injection molding machine oil supply completion signal to the injection molding machine.

[0045] 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 the first oil supply pipeline, and stop supplying lubricating oil to the injection molding machine, so as to automatically stop supplying lubricating oil to the injection molding machine after the lubricating oil supplied to the injection molding machine meets the standard, and avoid the situation that the lubricating oil is less or more, and further automatically supply the lubricating oil to the injection molding machine.

[0046] In Figure 2 On the basis of the embodiment shown, the oil supply equipment can further include a second pressure detection element arranged on the second oil supply pipeline. For details, refer to Figure 3 , Figure 3 is another schematic diagram of the oil supply equipment provided by the embodiment. As Figure 3 shown, the oil supply equipment 100 provided by the embodiment includes a lubricating oil storage device 200, an oil pump 300, an oil supply pipeline control component 400, an injection molding machine 500, a mechanical arm 600, a first pressure detection element 700, and a second pressure detection element 800. The lubricating oil storage device 200 is in communication with the oil pump 300, the oil pump 300 is in communication with the oil supply pipeline control component 400, the oil supply pipeline control component 400 is in communication with the injection molding machine 500 via a first oil supply pipeline 110, the first pressure detection element 700 is arranged on the first oil supply pipeline 110, the oil supply pipeline control component 400 is in communication with the mechanical arm 600 via a second oil supply pipeline 120, the second pressure detection element 800 is arranged on the second oil supply pipeline 120, the mechanical arm 500 is connected to the injection molding machine 600, and the injection molding machine 600 is connected to the oil pump 300 and the oil supply pipeline control component 400.

[0047] In the embodiment, similar to the first pressure detection element, in order to realize automatic lubrication of the mechanical arm, a second pressure detection element can be arranged on the second oil supply pipeline, which can be used to detect the liquid pressure of the lubricating oil on the second oil supply pipeline. In the case that the liquid pressure detected by the second pressure detection element is greater than or equal to a preset liquid pressure value, the second pressure detection element can feed back a mechanical arm oil supply completion signal to the mechanical arm. After the mechanical arm receives the mechanical arm oil supply completion signal, a mechanical arm oil supply shutdown signal can be transmitted to the injection molding machine.

[0048] After the injection molding machine receives the mechanical arm oil supply shutdown signal, the oil supply pipeline control component can be controlled to no longer connect the second oil supply pipeline, and stop supplying lubricating oil to the mechanical arm, so as to automatically stop supplying lubricating oil to the mechanical arm after the lubricating oil supplied to the mechanical arm meets the standard, and avoid the situation that the lubricating oil is less or more, and further automatically supply the lubricating oil to the mechanical arm.

[0049] In an embodiment of the present application, the first pressure detection element and the second pressure detection element are hydraulic pressure switches.

[0050] In an embodiment of the present application, the first pressure detection element and the second pressure detection element are hydraulic pressure switches. For the first pressure detection element, the first pressure detection element can be in a closed state by default, and in a case where the detected liquid pressure is greater than or equal to a preset liquid pressure value, the first pressure detection element can be in an open state. In a case where the first pressure detection element is in the open state, the first pressure detection element can feed back an injection molding machine oil supply completion signal to the injection molding machine.

[0051] Similarly to the first pressure detection element, the second pressure detection element can be in a closed state by default, and in a case where the detected liquid pressure exceeds a preset value, the second pressure detection element can be in an open state. In a case where the second pressure detection element is in the open state, the second pressure detection element can feed back a robot oil supply completion signal to the robot. After receiving the robot oil supply completion signal, the robot can transmit a robot oil supply closing signal to the injection molding machine.

[0052] In the above embodiment, the preset liquid pressure value of the first pressure detection element and the preset liquid pressure value of the second pressure detection element can be the same or different, and can be set according to actual conditions and requirements.

[0053] In the above embodiment, the injection molding machine can include an injection molding machine body and a first controller, the robot can include a robot body and a second controller, and the first controller and the second controller are different. For details, please refer to Figure 4 , Figure 4 is another schematic diagram of an oil supply device provided in an embodiment of the present application. As shown in Figure 4 , the oil supply device 100 provided in the embodiment of the present application includes an oil storage device 200, an oil pump 300, an oil supply pipeline control component 400, an injection molding machine 500, and a robot 600. The injection molding machine 500 includes an injection molding machine body 510 and a first controller 520, and the robot 600 includes a robot body 610 and a second controller 620. The oil storage device 200 is in communication with the oil pump 300, the oil pump 300 is in communication with the oil supply pipeline control component 400, the oil supply pipeline control component 400 is in communication with the injection molding machine 500 via a first oil supply pipeline 110, the oil supply pipeline control component 400 is in communication with the robot 600 via a second oil supply pipeline, the robot 600 is connected to the injection molding machine 500, and the injection molding machine 500 is connected to the oil pump 300 and the oil supply pipeline control component 400.

[0054] In the embodiments of the present application, 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 mechanical arm oil supply closing signal and the mechanical arm oil supply starting signal mentioned above, and the second controller can be used to process signals received by the mechanical arm, such as the mechanical arm oil supply completion signal.

[0055] Meanwhile, the first controller can be used to set the automatic lubrication module number, the running module number, the next lubrication module number and the automatic lubrication alarm time of the injection molding machine. The automatic lubrication module number of the injection molding machine is used to describe the interval module number of the lubrication starting of the injection molding machine. For example, if the automatic lubrication module number of the injection molding machine is 16, the injection molding machine will start the lubrication process every 16 modules. When the injection molding machine starts lubrication, the running module number is 0 and the next lubrication module number is equal to the automatic lubrication module number of the injection molding machine. After one cycle is performed, the running module number is increased by 1 and the next lubrication module number is decreased by 1. When the next lubrication module number is 0, the injection molding machine lubrication starting signal is output. After the current lubrication of the injection molding machine is completed, the next lubrication module number is restored to the set value of the automatic lubrication module number. After the lubrication action of the injection molding machine is performed, if the injection molding machine oil supply completion signal fed back by the first pressure detection element is not received 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 is cleared and the timing is restarted when the next lubrication of the injection molding machine is performed.

[0056] Correspondingly, the second controller can be used to set the automatic lubrication module number, the running module number, the next lubrication module number and the automatic lubrication alarm time of the mechanical arm. The automatic lubrication module number of the mechanical arm is used to describe the interval module number of the lubrication starting of the mechanical arm. The automatic lubrication module number and the automatic lubrication alarm time of the mechanical arm are similar to those of the injection molding machine, which will not be described here. In addition, the second controller can also be used to set the idle lubrication time of the mechanical arm. After the mechanical arm is started, the running module number of the current mechanical arm is 0, and the second controller can determine the time difference from the last shutdown of the mechanical arm according to the system time. If the time difference is greater than the idle lubrication time, the second controller can actively transmit the mechanical arm oil supply starting signal to the injection molding machine to perform a lubrication action of the mechanical arm, so as to avoid the situation that the mechanical arm is operated without sufficient lubrication after a long idle time, which may cause the service life of the mechanical arm to be shortened.

[0057] For details, please refer to Figure 5 , Figure 5 is the overall concept diagram of the oil supply equipment provided by the embodiments of the present application. As shown in Figure 5As shown, the automatic lubrication system comprises an oil pump and a first pressure detection element, a first controller in the injection molding machine can transmit an oil pump opening 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, and the first controller can receive an 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 reaches, the second controller can transmit a manipulator lubrication starting signal to the first controller through an input / output (I / O) interface or other communication modes, and after the first controller receives the manipulator lubrication starting signal, the first controller can transmit an 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 a second pressure detection element on the second oil supply pipeline. The second controller can receive a manipulator oil supply completion signal fed back by the second pressure detection element.

[0058] In the case that the automatic lubrication modulus of the injection molding machine and the automatic lubrication modulus of the manipulator reach at the same time, the lubrication of the injection molding machine can be performed first, and then the lubrication of the manipulator is performed. Specifically, after the first controller receives the manipulator oil supply starting signal, it can first determine whether the automatic lubrication modulus of the injection molding machine reaches. In the case that the automatic lubrication modulus of the injection molding machine does not reach, the injection molding machine can issue an oil pump opening instruction to the oil pump, and at the same time, transmit an oil supply pipeline switching signal to the oil supply pipeline control component, at this time, the oil pump lubricates the manipulator. In the case that the automatic lubrication modulus of the injection molding machine reaches, the oil pump lubricates the injection molding machine first, and then lubricates the manipulator after the lubrication of the injection molding machine is completed.

[0059] Wherein, the automatic lubrication modulus of the injection molding machine reaching means that the modulus of the current distance from the last oil supply completion of the injection molding machine is equal to the automatic lubrication modulus of the injection molding machine, and the automatic lubrication modulus of the manipulator reaching means that the modulus of the current distance from the last oil supply completion of the manipulator is equal to the automatic lubrication modulus of the manipulator. That is to say, the automatic lubrication modulus of the injection molding machine reaching means that a new round of oil supply of the injection molding machine is started.

[0060] In the process that the oil pump performs lubrication action on the injection molding machine or the manipulator, the automatic lubrication time, the automatic lubrication delay and the automatic lubrication times of the oil pump can be automatically recorded. The automatic lubrication time is the single working time of the oil pump, the automatic lubrication delay is the time that the oil pump stops working and waits for the next oil pump opening, at this time, the lubricating oil can be pressed into the lubricating pipeline through the distributor. The automatic lubrication times is the number of times that the oil pump performs the "automatic lubrication time" and "automatic lubrication delay" in one lubrication period.

[0065] The oil supply equipment provided by the embodiment of the application comprises an oil storage device, an oil pump, an oil supply pipeline control component, an injection molding machine and a robot. The oil storage device is connected with the oil pump in communication, the oil pump is connected with the oil supply pipeline control component in communication, the oil supply pipeline control component is connected with the injection molding machine in communication through a first oil supply pipeline, the oil supply pipeline control component is connected with the robot in communication through a second oil supply pipeline, the robot is connected with the injection molding machine, and the injection molding machine is connected with the oil pump and the oil supply pipeline control component. In this way, the injection molding machine and the robot can be supplied with oil through the oil supply pipeline control component, that is, the injection molding machine can be supplied with oil through the first oil supply pipeline, and the robot can be supplied with oil through the second oil supply pipeline. That is, the injection molding machine and the robot can share the oil supply equipment. In this way, it is no longer necessary to provide two sets of lubricating systems for the robot and the injection molding machine, the lubricating cost is reduced, and the problem of high cost in the related art is solved.

[0066] The oil supply equipment provided by the embodiments of the present application can also have the following beneficial effects: first, the lubrication of the manipulator in the related art is usually manually added by artificial oiling, and this manual lubricating oil adding method has uncertainty, and the present application can automatically start and complete the lubrication of the manipulator by setting the number of operations (automatic lubricating modulus), thereby effectively solving the problems of missing lubricating oil or not timely adding oil. Second, the lubrication of the manipulator can be automatically stopped based on the hydraulic pressure switch when the lubrication of the manipulator is completed, thereby avoiding the problems of over-lubrication or under-lubrication, and prewarning the problems of insufficient lubricating oil in the tank, too short lubricating time, and oil leakage in the lubricating pipeline. Third, the injection molding machine and the manipulator can share the lubricating oil supply system of the injection molding machine, thereby effectively saving costs. Fourth, the lubricating pipeline of the injection molding machine and the lubricating pipeline of the manipulator are separately arranged, and the lubricating control parameters of the injection molding machine and the manipulator are separately arranged, thereby avoiding the problems that may occur when the lubricating start operation modulus of the two is inconsistent. Fifth, the oil pump and the oil tank of the injection molding machine can be installed at a lower position away from the injection structure, thereby making oiling more convenient and reducing the risk of falling and scalding. Sixth, after the manipulator is idle for a long time, the manipulator can perform automatic lubrication when it is started.
