[0033] Compared with the prior art, the utility model can at least achieve the following beneficial effects. When the engine is off the production line, due to the large mass of the engine, a pallet is usually used to transport the engine. In order to facilitate the positioning of the engine in the subsequent process, the position of the engine on the pallet is a fixed position. After the engine is off the production line, the engine is transported to the filling system by a pallet, and the positioning cylinder in the chassis accurately positions the pallet. Positioning the pallet is a prior art and will not be described in detail here. After the pallet is positioned, the pallet information reading device reads the pallet information to determine the engine model and synchronizes the engine model to the control cabinet.

In addition, in the prior art, after the engine lubricating oil is filled, the engine will be ignited. At this time, the lubricating oil inside the engine does not lubricate the components inside the engine. The ignition test will cause dry wear of the components inside the engine, and high-speed operation will cause damage to the components. In this system, the engine will be cranked before the ignition test. Unlike the ignition test, the engine will not run at a high speed during cranking, and it can promote the lubricating oil to infiltrate the components inside the engine, preventing the occurrence of dry wear.

[0046] Reference Figure 1~Figure 4 The utility model provides a multi-model engine lubricating oil filling system, characterized in that the filling system comprises:

[0047] A filling station 100, the filling station 100 includes a pallet information reading device, a filling robot 110, the filling robot 110 is provided with a filling gun, and part of the engine is located at the filling station 100;

[0048] The turning station 200 is located at one side of the filling station 100, and part of the engine is located at the turning station 200;

[0049] The chassis 300, the filling station 100 and the turning station 200 are arranged on the chassis 300;

[0050] The filling machine 400 includes a liquid storage tank 410 and a heater 420. The liquid storage tank 410 is connected to a filling gun, and the heater 420 heats the liquid storage tank 410.

[0051] The control cabinet 500 is communicatively connected to the filling station 100 , the turning station 200 and the filling machine 400 .

[0052] When the engine is on and off the production line, due to the large mass of the engine, a pallet is usually used to transport the engine. In order to facilitate the positioning of the engine in the subsequent process, the position of the engine on the pallet is fixed. After the engine is off the production line, the engine is transported to the filling system by a pallet, and the positioning cylinder in the chassis 300 accurately positions the pallet. After the pallet is positioned, the pallet information reading device reads the pallet information to determine the engine model and synchronizes the engine model to the control cabinet 500. The control cabinet 500 sends different instructions to the filling station 100, the turning station 200 and the filling machine 400 according to the engine model. The above-mentioned pallet positioning technology and pallet information reading technology are existing technologies and will not be described in detail here.

[0053] The filling machine 400 supplies a corresponding amount of lubricating oil to the refueling gun according to the model of the engine, the cranking station 200 determines the meshing position with the engine according to the model of the engine, and the filling robot 110 moves the filling gun to the filling port of the engine according to the model of the engine, thereby improving the overall automation of the system. The technical problem that the current filling system can only fill one model of engine or requires more manual intervention when filling different models of engines is solved. In addition, in the prior art, after the filling of the engine lubricating oil is completed, the engine will be subjected to an ignition test. At this time, the lubricating oil inside the engine does not lubricate the components inside the engine. The ignition test will cause dry wear of the components inside the engine, and high-speed operation will cause damage to the components. In this system, the engine will be cranked before the ignition test. Unlike the ignition test, the engine will not run at high speed during cranking, and it can promote the lubricating oil to infiltrate the components inside the engine, thereby preventing the occurrence of dry wear in the subsequent ignition test.

[0054] Specifically, the cranking action of the engine and the lubricating oil filling action are performed synchronously. When the lubricating oil of the engine is filled to the pre-lubricating point, the cranking action begins. For example, if 30L of lubricating oil needs to be added, when the lubricating oil in the engine is filled to the pre-lubricating point (such as 25L), the engine cranking and lubricating oil filling are performed synchronously at this time, and the lubricating oil is filled to 30L during the cranking process. Specifically, the cranking action time is 5s.

[0055] The filling robot 110 is a six-axis industrial robot, which has a high degree of freedom and can achieve complex movements and postures to ensure that the filling gun can be accurately aligned with the lubricating oil filling port of the engine.

[0056] Furthermore, the cranking station 200 includes a slide 210, a lifting platform 220 and a cranking mechanism 230. Through the sliding connection between the slide 210 and the chassis 300, the sliding connection between the lifting platform 220 and the slide 210, and the sliding connection between the cranking mechanism 230 and the lifting platform 220, the cranking mechanism 230 can move freely in the space to accurately engage with the engine flywheel to complete the cranking work.

[0057] Specifically, in a non-working state, the slide 210 is located on one side of the chassis 300, and the lifting platform 220 is located at the highest point of the slide 210, reserving sufficient space for the engine to enter the cranking station 200. When the engine enters the cranking station 200, according to the model of the engine, the first cylinder 240 drives the slide 210 to approach the engine in the y-axis direction, and the servo motor 250 drives the lifting platform 220 to approach the engine in the z-axis direction, and finally the second cylinder 260 drives the cranking mechanism 230 to move on the x-axis so that the flywheel of the engine can be accurately engaged during cranking.

[0058] Further, the cranking motor 270 drives the cranking mechanism 230 to engage with the engine and rotate to realize the cranking work of the engine. To ensure the engagement accuracy, the cranking mechanism 230 is connected with a floating spline 280 to assist the precise engagement between the cranking mechanism and the engine.

[0059] Further, see Figure 4 , the function of the filling machine 400 is explained.

[0060] The liquid storage tank 410 is used to store lubricating oil. At least two sensing points are set in the liquid storage tank 410, which are an upper limit liquid point and a lower limit liquid point (not shown). The liquid storage tank 410 is connected to a liquid replenishing pipeline 700. When the lubricating oil level in the oil storage tank is lower than the lower limit liquid point, the liquid replenishing pipeline 700 replenishes the liquid in the liquid storage tank 410. When the liquid is replenished to the upper limit liquid point, the liquid replenishment is completed. In other embodiments, the liquid storage tank 410 may also be set with an upper limit liquid point and a lower limit liquid point.

[0061] The filling machine 400 is provided with a heater 420 to heat the liquid storage tank 410. Specifically, the heating oil temperature is controlled within the range of 20 to 50 degrees Celsius. It is understandable that heating can reduce the forces between molecules and improve the fluidity of the lubricating oil, thereby reducing the filling time of the lubricating oil. In this embodiment, the heater 420 is arranged at the bottom of the liquid storage tank 410. In order to allow the lubricating oil in the liquid storage tank 410 to be evenly heated, a circulation pipeline 430 and an oil return pneumatic valve 440 are provided. The oil return pneumatic valve 440 is opened to drive the lubricating oil to circulate continuously in the liquid storage tank 410 and the circulation pipeline 430, so that the lubricating oil in the liquid storage tank 410 can be evenly heated.

[0062] In addition, the filling machine 400 also includes components such as a filter, a pressure reducing valve, a flow meter, and a pressure gauge, which are all connected to the oil outlet pipeline 450. The oil outlet pneumatic valve 490 is opened, and the oil is pressurized through the electric gear pump 600, and then flows through the filter and the pressure reducing valve in sequence and then flows to the filling gun to be filled into the engine. The flow meter and the pressure gauge are used to measure the oil in the oil outlet pipeline 450. In order to prevent the oil pressure in the pipeline from being too high and causing the pipe to burst, the threshold of the overflow valve 480 is set to be the same as the normal pressure measured by the pressure gauge. When the oil pressure in the oil outlet pipeline 450 exceeds the normal pressure, the oil is depressurized through the overflow valve 480 and flows back to the liquid storage tank 410 through the overflow pipeline 460.

[0063] It should be noted that during the filling process, the oil outlet pneumatic valve 490 is opened, and during the non-filling process, the oil return pneumatic valve 440 is opened, and the two cannot be opened at the same time. After the filling is completed, there is residual lubricating oil in the pipeline. Since the circulation pipeline 430 is connected to the oil outlet pipeline 450 through the valve plate 470, the residual lubricating oil can flow back to the liquid storage tank 410 from the circulation pipeline 430 through the pneumatic oil return pneumatic valve 440, completing the recovery of the residual lubricating oil.

[0064] An electric gear pump 600 is selected as the power source, a controller is set to control the filling machine 400 as a whole, and a FLOMEC gear flowmeter is selected as the flowmeter, and the linear error of its measuring range is not higher than ±0.5%, so that the filling machine 400 has the characteristics of high sensitivity, accurate measurement, high reliability, and long service life.

[0065] The control cabinet 500 is equipped with lubricating oil filling control system software, which mainly includes four modules: work interface, data query, adding order number, and manual operation. According to the scanned information, the system will automatically decompose into machine number, order number, program number, and set refueling amount according to the order number setting value added to the database. The program number is automatically sent to the robot and camera, and the corresponding program is called to execute the automatic lubricating oil filling of the engine. When the filling machine 400 completes the action, the refueling information is automatically saved to the database. The saved information includes the order number, actual refueling amount, equipment refueling program number, and refueling time. When the equipment detects the refueled engine, the system automatically prompts that the engine has been refueled when it is refilled for the second time. There are two main ways to query the software. You can query according to the order number or according to the date. The information of each unit is automatically saved to facilitate future product traceability.

[0066] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
