[0002] In the automotive manufacturing and maintenance industry, the installation and maintenance of engine filters and oil pans are crucial. As a key component that filters impurities from the oil and ensures the proper functioning of the engine's lubrication system, the filter's secure installation directly impacts the engine's service life and performance. The oil pan not only stores oil, but its internal magnetic components also absorb metal particles in the oil, further reducing wear on engine components. The oil pan's plug, meanwhile, seals and drains the oil, making its tightness and secure installation crucial to the proper functioning of the entire lubrication system.

The first Z-axis module 602 is fixed to the first X-axis module 601 and is used to drive the first mounting assembly 300 to move along the Z-axis direction. The second X-axis module 603 is fixed to the frame 100 and is used to drive the second mounting assembly 400 to move along the X-axis direction. The third X-axis module is fixed to the frame 100 and is used to drive the third mounting assembly 500 to move along the X-axis direction. The third Z-axis module 604 is fixed to the third X-axis module and is used to drive the third mounting assembly 500 to move along the Z-axis direction. The Y-axis module 605 is fixed to the frame 100 and is used to drive the worktable 200 to move along the Y-axis direction. The three-axis motion module is provided to realize the relative motion of the first mounting assembly 300 , the second mounting assembly 400 and the third mounting assembly 500 relative to the oil pan 110 .

[0024] like Figure 4-Figure 6As shown, the first mounting assembly 300 includes a base plate 301, a slide rail 302, a first sliding block 303, a second sliding block 304, a vertical rod 305, an elastic member 306, a first motor 307, a first cylinder 308, a support plate 309, a second cylinder 310 and a first batch head 311. The slide rail 302 is extended along the Z-axis direction and the bottom of the slide rail 302 is fixed on the base plate 301. The first sliding block 303 and the second sliding block 304 are both slidably connected to the slide rail 302, and the first sliding block 303 is located above the second sliding block 304. One end of the vertical rod 305 is fixedly connected to the second sliding block 304 and the other end is slidably connected to the first sliding block 303. The elastic member 306 is sleeved On the vertical rod 305, one end of the elastic member 306 is fixedly connected to the second sliding block 304 and the other end is fixedly connected to the first sliding block 303, the first motor 307 is fixedly connected to the first sliding block 303, the first batch heads 311 are coaxially fixedly connected to the output shaft of the first motor 307, the support plate 309 is fixedly connected to the first sliding block 303, the first cylinder 308 and the second cylinder 310 are respectively distributed on the upper and lower sides of the support plate 309, and the first cylinder 308 is fixedly connected to the support plate 309, the second cylinder 310 is fixedly connected to the base plate 301, and the first piston rod of the first cylinder 308 and the second piston rod of the second cylinder 310 are arranged opposite to each other and coaxially distributed along the Z-axis direction.

[0025] The first installation assembly 300 also includes a main pipe 312, a branch pipe 313, and a clamping member 314. The main pipe 312 is fixed to the base plate 301 and extends along the Z-axis. One end of the branch pipe 313 is connected to the main pipe 312 and the other end is connected to the vibration plate for conveying small screws. The clamping member 314 is arranged on the main pipe 312 to prevent the small screws from falling freely. The first batch head 311 is inserted into the main pipe 312. The clamping member 314 includes a pair of clamping blocks 3140 symmetrically arranged on both sides of the main pipe 312 and a spring clamped on the pair of clamping blocks 3140. Under normal circumstances, the pair of clamping blocks 3140 are moved together by the elastic force of the spring to cut off the main pipe 312 and prevent the small screws from falling freely. When installing the small screws, the first batch head 311 overcomes the elastic force of the spring and pushes the small screws out of the main pipe 312. At this time, the pair of clamping blocks 3140 are relatively separated.

[0026] The first mounting assembly 300 also includes multiple auxiliary pressing assemblies, which include a third cylinder 315 and a pressing head 316 fixedly connected to the piston rod of the third cylinder 315. The third cylinder 315 is fixed on the base plate 301 to drive the pressing head 316 to move along the Z-axis direction.

[0027] like Figure 7As shown, the second mounting assembly 400 includes a fourth cylinder 401 and a ferromagnetic element 402. The ferromagnetic element 402 is fixed to the end of the piston rod of the fourth cylinder 401. The magnetic member 130 is magnetically attracted to the ferromagnetic element 402. The fourth cylinder 401 is used to drive the ferromagnetic element 402 to move along the Z-axis direction and press the ferromagnetic element 402 into the mounting groove 111 of the oil pan 110. In addition, to ensure the accurate installation position of the magnetic member 130, the end of the ferromagnetic element 402 is concave to form a recessed portion 4020. The magnetic member 130 is adapted to the recessed portion, and the magnetic member 130 is at least partially exposed outside the recessed portion to avoid affecting the normal press-fitting of the magnetic member 130.

[0028] like Figure 8 As shown, the third mounting assembly 500 includes a second motor 501 and a second screwdriver 502, which is coaxially fixedly connected to the output shaft of the second motor 501. In this embodiment, the plug is hexagonal, so the end of the second screwdriver 502 has a hexagonal hole adapted to the plug.

[0029] In addition, reference Figure 3 , a plurality of pressing components 700 are still provided on the workbench 200, and the pressing components include a pressing cylinder 701, a base 702, a connecting member 703, a driving block 704 and a pressing block 705. The base 702 is fixed to the main body of the pressing cylinder 701, one end of the connecting member 703 is rotatably connected to the base 702 through a first rotating shaft 706, and the other end is connected to the driving block 704 through a second rotating shaft 707, one end of the driving block 704 is rotatably connected to the piston rod of the pressing cylinder 701 through a third rotating shaft 708, the pressing block 705 is fixed to the other end of the driving block 704, and the second rotating shaft 707 is located between the pressing block 705 and the third rotating shaft 708. When the oil pan 110 needs to be compressed, the piston rod of the pressing cylinder 701 extends, driving the pressing block 705 through the connecting member 703 and the driving block 704 to move, thereby pressing the oil pan 110. Conversely, when release is required, the piston rod of the pressing cylinder 701 retracts. In this embodiment, four pressing assemblies 700 are provided, one near each of the four corners of the oil pan 110.

[0030] Here's how this application works: Overall workflow: When automated assembly of an oil pan is required, the pre-tightened plug is first manually assembled onto the oil pan 110. The oil pan 110 is then manually placed on the workbench 200. Driven by the Y-axis module 605, the workbench 200 can move along the Y-axis to precisely position the oil pan 110 for each assembly. The piston rod of the pressing cylinder 701 then extends, driving the pressing block 705 through the connector 703 and the drive block 704 to press the oil pan 110, ensuring its stable position during installation. The first, second, and third mounting assemblies 300, 400, and 500 then perform their corresponding installation operations.

[0031] Working principle of the first installation component The first installation assembly 300 is responsible for installing small screws fed from the vibrating plate onto the oil pan 110, securing the filter element 120 to the oil pan 110. Prior to installation, the piston rods of the first and second cylinders 308 and 310 are both extended. At this point, the first motor 307 is in a relatively high position, preventing the first set of screws 311, connected to the first motor 307, from interfering with the screws' proper entry into the main pipe 312. When the first installation assembly 300 begins operation, the small screws are first fed from the vibrating plate into the main pipe 312 via the branch pipe 313. The clamp 314 temporarily blocks the screws' free fall. Then, the first X-axis module 601 drives the first installation assembly 300, while the Y-axis module 605 drives the worktable 200, positioning the first set of screws 311 directly above the screw-driving position. Next, the piston rod of the second cylinder 310 retracts, causing the first motor 307 to descend a certain distance, allowing the first set of screws 311 to pre-engage the small screws. Then the first Z-axis module 602 drives the first mounting assembly 300 to descend to the preset position. Then, the auxiliary pressing assembly is started, and the third cylinder 315 drives the pressing head 316 to press the oil pan 110. Subsequently, the piston rod of the first cylinder 308 contracts, the entire first motor 307 descends, and the first batch of heads 311 push the small screws out of the main pipe 312 to the screw-driving position. Finally, the first motor 307 is started to drive the first batch of heads 311 to rotate to execute the rotation of the small screws. The steps for tightening other small screws are the same as the above-mentioned action process and will not be repeated here.

[0032] Working principle of the second installation component The second mounting assembly 400 is used to press-fit the magnetic component 130 onto the oil pan 110. The magnetic component 130 is magnetically attracted to the ferromagnetic element 402. The second X-axis module 603 drives the second mounting assembly 400 to move above the mounting slot 111 of the oil pan 110. The fourth cylinder 401 drives the ferromagnetic element 402 downward along the Z-axis, press-fitting the magnetic component 130 into the mounting slot 111 of the oil pan 110.

[0033] Working principle of the third installation component The third mounting assembly 500, located below the workbench 200, is responsible for tightening the plug on the oil pan 110. The third X-axis module and the third Z-axis module 604 drive the third mounting assembly 500 to the plugging position. The second motor 501 is activated, driving the second screwdriver 502 to rotate and tighten the plug.

[0034] This application has the following beneficial effects: 1. Improved assembly efficiency: By incorporating a three-axis motion module, the first mounting assembly 300, the second mounting assembly 400, and the third mounting assembly 500 achieve relative motion with the oil pan 110. Each component can quickly and accurately reach its working position, significantly improving assembly efficiency. Compared to traditional manual assembly methods, this equipment can complete the assembly of the oil pan 110 in a fraction of the time, meeting the needs of large-scale production.

[0035] 2. Ensure assembly quality: The elastic member 306 in the first installation component 300 acts as a buffer to avoid damaging the oil pan 110 or the filter element 120 due to excessive force when installing small screws, thereby ensuring the stability of the installation of small screws. At the same time, the auxiliary pressing component can ensure the stability of the position of the filter element 120 during the installation process, further improving the assembly quality. The second installation component 400 uses the ferromagnetic element 402 to adsorb the magnetic member 130, and can accurately press the magnetic member 130 into the installation groove 111 of the oil pan 110, avoiding problems such as missing installation and wrong installation that may occur during manual installation. The third installation component 500 can accurately tighten the plug on the oil pan 110, ensuring the sealing of the plug and preventing oil leakage.

[0036] 3. Reduced Labor Intensity: This automated equipment automates previously manual operations such as tightening screws, installing magnetic components, and tightening plugs, significantly reducing worker labor intensity. Workers simply place the oil pan 110 on the workbench 200, and the equipment automatically completes the subsequent assembly, reducing fatigue and errors associated with manual operation.

[0037] 4. Strong scalability: The three-axis motion module and various mounting components of the equipment are designed to be scalable. The range of motion of the motion module and the structure of the mounting components can be adjusted according to the assembly requirements of different oil pan models to meet diverse production needs.

[0038] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
