[0002] The oil pump is a core component of the lubrication system of an automobile engine. It is mainly used to pressurize the engine oil in the oil pan and deliver it to various friction surfaces of the engine (such as the crankshaft, camshaft, piston, etc.) to form an oil film to reduce wear. At the same time, it ensures the continuous circulation of the engine oil in the lubrication system to maintain the normal operating temperature and cleanliness of the engine.

[0003] As the "heart" of the engine, the performance of the oil pump directly affects the engine life. After long-term use of the engine, a large amount of impurities will be generated. The oil pump filter screen (strainer) is located between the oil pan and the oil pump and is used to filter large particle pollutants such as metal debris and mechanical impurities in the engine oil. Its core function is to protect the oil pump and the subsequent lubrication system to prevent impurities from entering and causing wear or blockage. At present, the oil pump filter screen valve plate is mainly installed manually, which is prone to incomplete installation. Moreover, the installation accuracy requirements for the solenoid valve plate on the current oil pump are high. If the installation is not in place, the solenoid valve plate cannot work properly, resulting in blockage or valve plate failure, which increases the wear of the engine.

[0004] Therefore, those skilled in the art are committed to developing an automatic assembly device for oil pump filter screen valve plates, which is conducive to quickly installing the valve plate to the specified position and improving the installation accuracy of the valve plate.

[0033] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, an automatic assembly device for an oil pump filter screen valve plate includes a conveying assembly 1 for conveying an oil pump housing; a mold assembly 2 having a positioning assembly 3 for positioning the oil pump housing and a fixing assembly 4 for fixing the oil pump housing; a pressing assembly 5 installed on the side wall of the mold assembly 2 and used for automatically pressing the valve plate into the oil pump housing.

[0034] In the present invention, through the mutual cooperation of the conveying assembly 1, the mold assembly 2, and the pressing assembly 5, the automation of the assembly processes such as the conveying of the oil pump housing and the automatic pressing of the valve plate is realized, replacing the traditional manual installation method, greatly improving the assembly efficiency, facilitating the rapid completion of the assembly work of the oil pump filter screen valve plate on a large-scale production line, and enhancing the overall production capacity.

[0035] As Figure 1 , Figure 2As shown, in some embodiments, the conveying assembly 1 includes between a first conveying bracket 6 and a second conveying bracket 7. Conveying sprockets 8 are installed on both the first conveying bracket 6 and the second conveying bracket 7. Through the chain drive principle, these conveying sprockets 8 drive the conveying plate 13 disposed thereon to move, thereby carrying the oil pump housing for displacement. A conveying plate 13 is provided on the conveying sprocket 8, and a positioning member for precisely positioning the oil pump housing is installed on the conveying plate 13. The conveying sprocket 8 is connected to a power assembly (not shown in the figure), and the power assembly is electrically connected to the control assembly (not shown in the figure). The power assembly can adopt a reduction motor. The power assembly provides power support for the entire conveying process, enabling it to operate at a preset speed and rhythm. And the power assembly is electrically connected to the control assembly, so that the conveying action can be precisely regulated according to the control instruction, realizing the automation and intelligence of the conveying process.

[0036] As Figure 1 , Figure 2 shown, in another embodiment, a mounting plate 9 is provided between the first conveying bracket 6 and the second conveying bracket 7. A plurality of lifting cylinders 10 are installed on the mounting plate 9. In this embodiment, four lifting cylinders 10 are installed on the mounting plate 9, and the four lifting cylinders 10 are respectively located at the four corners of a rectangle. A top block 11 is installed at the output end of the lifting cylinder 10. When the lifting cylinder 10 extends, the upper end of the top block 11 is higher than the outer edge of the upper end of the conveying sprocket 8 and jacks up the conveying plate 13. A positioning baffle 12 is further provided on the first conveying bracket 6 and on the side wall of the mounting plate 9. When one set of the first conveying bracket 6 and the second conveying bracket 7 conveys the conveying plate 13 to the second set of the first conveying bracket 6 and the second conveying bracket 7, the positioning baffle 12 is used to position the position of the conveying plate 13, and then the lifting cylinder 10 acts to jack up the conveying plate 13 to disconnect it from the conveying sprocket 8, which is beneficial for subsequent manual picking up of the oil pump housing or for subsequent picking up of the oil pump housing by the manipulator 26.

[0037] As Figure 1 , Figure 3 shown, in the embodiment, the mold assembly 2 includes a mold plate 14. The mold plate 14 is disposed on a mounting table 15. The positioning assembly 3 includes at least one positioning pin 16. The positioning pin 16 is installed on the mold plate 14. A plurality of positioning pins 16 are precisely installed on the mold plate 14. By cooperating with the corresponding hole positions on the oil pump housing, precise positioning of the housing is achieved.

[0038] The fixing component 4 includes a fixing cylinder 17 and a rotating cylinder 18. The fixing cylinder 17 and the rotating cylinder 18 are arranged oppositely. A connecting rod 19 is hinged to the output end of the rotating cylinder 18. A fixing block is installed at the end of the connecting rod 19. The middle part of the connecting rod 19 is connected to the fixing cylinder 17 through a hinging component. When the fixing cylinder 17 expands and contracts, the middle part of the connecting rod 19 rotates around the hinging component, so that the fixing block tightly presses the oil pump housing. The output end of the rotating cylinder 18 is connected to a pressing rod 20. A pressing block is installed at the end of the pressing rod 20. When compressed air is introduced into the rotating cylinder 18, the rotating cylinder 18 rotates 180° and its output end contracts, so that the end of its pressing rod 20 tightly presses the oil pump housing. The fixing cylinder 17 and the rotating cylinder 18 are arranged oppositely to form a multi-point clamping structure for the oil pump housing.

[0039] In the embodiment, the pressing component 5 includes a pressing cylinder 21. The pressing cylinder 21 is installed on the side wall of the mold component 2. The output end of the pressing cylinder 21 is installed with a pressing cylinder 22. When it is necessary to press the valve plate into the oil pump housing, the pressing cylinder 21 receives a control signal and extends, driving the pressing cylinder 22 to move parallelly, so as to accurately press the valve plate placed at the corresponding position of the oil pump housing into the housing interior, ensuring that the valve plate is tightly fitted with the housing and completing the key process of automatic assembly.

[0040] The side wall of the mold component 2 is also connected with a telescopic cylinder 23. The output end of the telescopic cylinder 23 is connected with a laser marking machine 24. Through the telescopic movement of the telescopic cylinder 23, the position of the laser marking machine 24 can be adjusted, so that it can perform marking operations on the oil pump housing at a suitable angle and distance, enabling the device to not only complete the automatic assembly of the valve plate, but also immediately mark the oil pump housing after the assembly is completed, facilitating subsequent product traceability and management.

[0041] As Figure 1 、 Figure 4 shown, a manipulator 26 is also arranged on the side of the conveying component 1. A clamping seat is installed at the output end of the manipulator 26. A first clamping piece 27 for clamping the oil pump housing and a second clamping piece 28 for clamping the valve plate are respectively installed on both sides of the clamping seat. To ensure the timeliness and stability of the valve plate supply, a valve plate rack 25 is also arranged on the installation table 15 for neatly storing the valve plates to be assembled, facilitating the manipulator 26 to pick up at any time. The manipulator 26 can act according to a preset program, and use the first clamping piece 27 and the second clamping piece 28 to respectively grab the oil pump housing and the valve plate. First, the oil pump housing is clamped by the first clamping piece 27 and accurately placed and fixed on the mold component 2, and then the first clamping piece 27 is driven to clamp the valve plate and place it at the pressing position, facilitating the subsequent automatic pressing by the pressing component 5.

[0042] Meanwhile, to improve the intelligent level of the production process and the quality monitoring ability, a vision sensor 29 is equipped on the installation table 15. The vision sensor 29 is used to detect the number of valve plates, prevent production interruption caused by material shortage, and is electrically connected to the control component, capable of real-time feedback of the detected signal to the control center, so as to timely adjust the production rhythm or perform replenishment operations.

[0043] In other embodiments, on both sides of the first conveying bracket 6 and the second conveying bracket 7, a set of guide wheel groups are additionally provided. Each set of guide wheel groups includes multiple guide wheels evenly distributed along the conveying direction. These guide wheels are used for side guiding of the conveying plate 13 to ensure that the conveying plate 13 can run smoothly and linearly under the drive of the conveying sprocket 8, effectively avoiding the problem of the position deviation of the oil pump housing caused by the deviation of the conveying plate 13, and further improving the stability of conveying.

[0044] A pressure sensor is added to the output end of the pressing cylinder 21 of the pressing assembly 5 to real-time monitor the pressure value during the pressing process and transmit the data to the control component. The control component precisely controls the pressing process according to the preset pressure range to ensure that the valve plate can be pressed into the oil pump housing with appropriate and uniform pressure. When the pressure value detected by the pressure sensor exceeds or is lower than the set range, the control component will timely adjust the output pressure of the pressing cylinder 21 to ensure the stability of the valve plate pressing quality. In addition, the material of the pressing cylinder 22 is specially treated (such as chrome plating), with higher surface hardness and good wear resistance, which can effectively resist the wear caused by long-term pressing operations and ensure the service life and pressing accuracy of the pressing cylinder 22.

[0045] A material buffer area is added on the installation table 15. The material buffer area is located beside the valve plate rack 25. The valve plate rack 25 with the valve plates placed is placed in the material buffer area. When the valve plates on the installation table 15 are used up, the vision sensor 29 transmits the signal of adding materials to the control component, and the control component controls the manipulator 26 to remove the empty valve plate rack 25 and place the valve plate rack 25 with the valve plates placed at the material taking position.
