[0015] Multi-station water pump barrel and stator assembly device for highly efficient and automated production: The device adopts a multi-station turntable design. Through the continuous rotation of the turntable body, the entire process of stator loading and unloading is fully automated, greatly reducing manual intervention and improving production efficiency. Each station has a clear division of labor, allowing different assembly steps to be carried out in parallel, shortening the processing cycle of a single product.

[0016] The water pump rotor bearing assembly device features a linearly arranged feed cylinder and discharge chute design: by arranging the feed cylinders in a straight line and directly connecting them to the discharge chute, an orderly and efficient supply of bearings is achieved. This design simplifies the bearing conveying process, reduces jamming or misalignment of bearings during transfer, and improves the continuity and stability of the feeding process.

[0017] The water pump positioning washer screw assembly device features a highly efficient assembly process: The ingeniously designed positioning washer clamping mechanism, through the coordinated work of the clamping head and clamping plate, ensures not only the rapid and accurate insertion of the positioning washer but also its secure clamping, providing a reliable foundation for subsequent screw assembly. The screw-driving mechanism, through automated screw feeding and a precision rotating bit, achieves efficient and stable screw tightening, further improving assembly efficiency. While clamping the positioning washer in the corresponding screw hole, screws can be driven into the already clamped screw hole, significantly reducing assembly time and greatly improving assembly efficiency.

[0018] The water pump air tightness testing and oil injection device features an integrated design that improves efficiency: By integrating multiple processes such as loading and unloading, visual inspection, air tightness testing, rotor rotation, and one-time oil injection into a compact circular workbench, it enables continuous operation from loading to completing multiple key assembly steps, greatly reducing waiting time and material handling in traditional processes, thereby significantly improving the overall efficiency of the assembly line.

[0019] The automated water pump parts assembly device includes an oil filler screw mounting section: This section utilizes a high-degree-of-freedom oil filler screw mounting head and a vision inspection mechanism to achieve precise screw positioning and tightening. The vision inspection mechanism ensures the accuracy of the screw installation position, while the oil filler screw mounting head, in conjunction with a negative pressure mechanism, efficiently completes the screw tightening operation while maintaining necessary torque control. Furthermore, after suction, it can extract O-rings for installation at the end of the water pump, further integrating the O-ring installation process. The screw mounting section is similar to the oil filler screw mounting section, but uses a dedicated screw mounting head, demonstrating the device's multi-functionality and improving its overall integration.

[0020] The water pump integrated marking assembly device includes a laser marking section: As the starting point of the assembly process, this section achieves precise laser marking through an adjustable galvanometer. The highest temperature during laser marking occurs before the installation of anti-sand sleeves, flat pads, and rubber sleeves, preventing melting. Subsequent installation of these components allows the water pump to cool down, avoiding the peak laser marking temperature, significantly reducing the risk of melting. The flat pad placement section features an adjustable suction head and blocking grippers, along with a flat pad vibratory feeder, to automatically pick up, place, and precisely position the flat pad. The tapered design of the lifting end is for better compatibility with the suction head and flat pad, ensuring stability and accuracy during placement.

[0021] The pump end parts assembly device and bottom end cover adjustment and installation mechanism utilize an adjusting lifting seat, a movable adjusting clamp, and a liftable and rotatable installation tray to achieve precise alignment and installation of the end cover, improving the flexibility and accuracy of assembly while shortening the assembly time.

[0022] The various devices are connected by a robotic arm to transfer the water pump body, forming a complete automated assembly line for water pump assembly, which greatly improves assembly efficiency, quality, and precision.

The elastic support frame design effectively absorbs vibrations during assembly, further improving assembly quality.

[0030] Pressure control optimization: The independent pressing barrel clamp and pressing stator clamp in the pressing mechanism can stably fix the barrel and stator, realize the tight pressing of the stator and barrel, improve the pressing accuracy, and the elastic support frame accurately applies pressure under load, avoiding excessive pressure from damaging the structure and extending service life.

[0031] Intelligent Management: The entire system is centrally managed by a controller, enabling coordinated operation of the drive mechanism, station detection mechanism, and pressing mechanism. This intelligent control not only improves response speed but also adjusts operating parameters based on real-time feedback, ensuring that each operation reaches its optimal state.

[0032] Optionally, the water pump rotor bearing assembly includes:

[0033] The feeding section includes a feeding structure and a moving structure, wherein the feeding structure moves along a planned path, and the feeding structure is linked to the discharging section and the pressing section along the moving path;

[0034] The pressing part includes: a rotor fixing structure and a pressing structure. The rotor fixing structure includes: a movable fixing fixture and a support block. The movable fixing fixture includes: a movable pressing block located above. The pressing block and the support block are movably adapted to each other and have a notch in the middle for accommodating the rotor.

[0035] Application of discharge claws and pusher plates: The discharge claws ensure that the bearings are precisely pushed into the discharge chute and ultimately reach the assembly position, reducing the need for manual intervention and improving assembly accuracy. The uniform pushing mechanism of the pusher plates further guarantees the consistency of the pushing action and the control of force, avoiding unnecessary damage to the bearings. The pushing efficiency is significantly improved compared to traditional discharge methods.

[0036] The ingenious design of the pressing section: the cooperation between the movable fixing fixture and the support block in the rotor fixing structure, especially the notch design between the pressing block and the support block that can accommodate the rotor, not only ensures the accurate positioning of the rotor during the pressing process, but also allows the robotic arm to grab the rotor from above, which is direct and efficient. Compared with the traditional top and bottom clamping method, which requires clamping from the side and has a winding path, the top gripping method of this solution has a straight up and down path, which greatly improves the efficiency compared with the traditional method.

[0047] The workstation interacts with the loading and unloading rotating fixture. Each workstation is equipped with a clamp, which cooperates with the rotating clamp to transfer the water pump body.

[0048] Improved space utilization: The circular worktable divides the mechanism into a ring, requiring only one loading and unloading rotating fixture to achieve loading and unloading. The loading and unloading rotating fixture does not need to move, only rotate. Among the factors affecting the movement time, distance is the key, while rotation only depends on the rotation speed. This significantly improves the overall efficiency of the assembly line while saving space.

[0049] Precise positioning and clamping: Utilizing a freely rotating turntable and a freely retractable rotating clamp design, along with multiple stations on the curved plate, ensures that each pump body is precisely positioned and securely clamped at every stage of processing. This not only improves assembly accuracy and stability but also reduces quality issues caused by inaccurate positioning or unstable clamping.

[0050] Automation and Intelligence: The integrated vision inspection mechanism enables rapid inspection of the pump body before assembly, ensuring that components with correct positions and angles proceed to subsequent processes. The airtightness testing mechanism automates inspection, reducing manual intervention and improving consistency and reliability. The rotor rotation mechanism rotates appropriately before oil injection, aiding in the detection of airtightness at different rotor rotation angles and improving the effectiveness of airtightness testing.

[0051] Reduced reliance on manual labor: The design of the entire device reduces reliance on manual operation. Automated loading and unloading and material transfer between workstations not only reduce the labor intensity of workers but also reduce human error and improve production quality and consistency.

[0073] Screw and washer feeding mechanism: An integrated feeding system that includes automatic feeding of washers and screws. Through the cooperation of a vibratory feeder and a feeding bit, it achieves rapid and accurate supply of parts, reduces manual intervention, and improves the continuity and efficiency of the assembly line.

[0074] Positioning and clamping mechanism and vision positioning and detection installation mechanism: The high-precision positioning and clamping mechanism ensures the stability of the water pump barrel during assembly. Combined with the vision positioning and detection system, it can not only monitor the assembly process in real time and ensure assembly quality, but also further improve the accuracy and reliability of assembly through the precise positioning and installation of the probe holder.

[0075] The assembly equipment, through the integrated application of highly automated, precision adjustment and intelligent detection technologies, has significantly improved the efficiency and quality of assembling pump end parts and reduced labor costs.

[0076] The assembly method for a fully automated water pump assembly line includes the following steps:

[0077] ① The robotic arm places the barrel onto the barrel pre-positioning mechanism and the stator onto the stator pre-positioning mechanism. Sensors and a vision inspection mechanism detect the rotation angles of the barrel and stator. The rotation angles of the barrel and stator are adjusted to the required fitting angles by the barrel bottom clamping drive and the stator bottom rotating motor. The robotic arm then places the barrel onto the loading station and the stator onto the stator auxiliary fixture. The auxiliary fixture moves down, placing the stator at the barrel opening. The turntable body rotates. The barrel and stator are fixed using the pressing barrel clamp and pressing stator clamp. The pressing mechanism is activated to press and assemble the barrel and stator, which have rotated to the pressing station. Then, the turntable body rotates, and the assembled barrel and stator move to the unloading station. The station lifting mechanism is activated to push them out a certain distance. The robotic arm removes the assembled barrel and stator and places them onto the unloading transfer mechanism for unloading.

[0078] ② The robotic arm transports the barrel from step ① to the inlet of the water pump rotor bearing assembly device, and quickly discharges the material through the feeding cylinder and discharge chute of the discharge section. Then, the rotor and bearing are pressed and assembled through the pressing section.

[0079] ③ The robotic arm transports the barrel from step ② to the inlet of the water pump positioning shim screw assembly device. The barrel loading and conveying mechanism loads the barrel, and the barrel is moved by the barrel clamping mechanism and the station shift fork mechanism. The angle of the barrel is adjusted and the barrel and the upper bearing seat are pressed at the end face visual alignment mechanism. After the adjustment is completed, the barrel is flipped by the robotic arm so that the end faces of the barrel and the upper bearing seat are facing down. The end faces of the barrel and the upper bearing seat are located in the middle of the positioning shim pressing mechanism and the screw driving mechanism. After starting, the process of pressing the positioning shim and driving the screw is realized. Then the unloading and conveying mechanism and the unloading and transfer mechanism unload the barrel.

[0080] ④ The robotic arm transfers the barrel from step ③ to the inlet of the water pump airtightness test oil injection. The water pump body is transferred to the loading and unloading rotating fixture via the loading and unloading transfer fixture. The rotating fixture transfers the water pump body to the vision inspection mechanism and visually aligns the rotation angle of the oil injection hole. The water pump body is rotated to the predetermined angle via the rotating fixture to align the oil injection hole. The rotating fixture takes the water pump body to the airtightness test mechanism. The airtightness test fixture clamps the water pump body. The airtightness test lifting assembly presses the oil injection port end face through the airtightness test head assembly and connects to the leak meter. After air injection, the leak meter detects the leakage amount and compares it with the maximum allowable leakage amount to determine whether it is qualified. The rotating fixture clamps the qualified water pump body after the airtightness test to the primary oil injection mechanism. The filling gun assembly adjusts the height through the primary oil injection lifting assembly to press the oil injection port. First, the water pump body is evacuated, and then oil is injected in a quantitative manner. The water pump body is moved to the secondary oil injection mechanism. After overflowing, the oil injection port is sealed.

[0081] ⑤ The robotic arm transfers the barrel from step ④ to the inlet of the automated water pump parts assembly device. The barrel is moved by the conveying unit and stops at the oil injection screw mounting part, screw mounting part and oil suction part to install the oil injection screw and screw and perform the oil suction process.

[0082] ⑥ The robotic arm transfers the barrel from step ⑤ to the inlet of the water pump integrated marking assembly device for laser marking, sandproof sleeve placement, sandproof sleeve pressing, flat pad placement, and rubber sleeve placement.

[0083] ⑦ The robotic arm transfers the barrel from step ⑥ to the inlet of the pump end parts assembly device. The pump barrel is moved to the pre-tightening pressing mechanism via the barrel transfer mechanism. The rotor is pressed by the pressing head to ensure that the rotor and pump barrel components are assembled in place. The robotic arm moves the pump barrel on the pressing plate to the positioning clamping mechanism. The end cover is adjusted in height by the bottom end cover adjustment mechanism. Then the adjusting fixture takes the end cover and moves it to the mounting tray. The mounting tray is activated so that the pump barrel and end cover are engaged. The barrel moving mechanism is activated to move the pump barrel to the support plate for screw and washer installation. The screw and washer feeding mechanism takes the screw and washer from the vibratory plate and moves them to the feeding bit. The feeding bit is installed below the support plate. Finally, the pump barrel is moved to the vision positioning and detection installation mechanism for vision positioning. The pump barrel is rotated by the installation positioning rotary motor and a probe seat is installed on the top.

[0084] This assembly method integrates automation, information technology, and intelligent technology, which improves production assembly efficiency, reduces costs, and enhances assembly quality and precision.

[0085] Optionally, both the drive mechanism and the sensor components are connected to the controller.

[0086] The controller is the brain of this production line system. It receives input information from sensors, processes this information according to preset control algorithms or artificial intelligence algorithms, and issues commands to the drive mechanism to control the operation of the entire system. In modern systems, the controller may be an embedded microprocessor, a programmable logic controller (PLC), an industrial PC, or a control system specifically designed for robots.

Detailed Implementation

[0183] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments.

[0184] Example

[0185] Referring to Figures 1-3, the multi-station water pump barrel and stator assembly device includes: a multi-station turntable 1, a station detection mechanism 2, a stator auxiliary tooling 3, a station lifting mechanism 4, a pressing mechanism 5, a barrel pre-positioning mechanism 6, a stator pre-positioning mechanism 7, a vision inspection mechanism 8, a material unloading and transfer mechanism 9, and a frame 10. The barrel is designated A, and the stator is designated B. The station detection mechanism 2 is divided into a loading detection unit 201 and a unloading detection unit 202. The loading detection unit 201 is aligned with the loading station 108, and the unloading detection unit 202 is aligned with the unloading station 1011. The loading detection unit 201 and the unloading detection unit 202 are position detection sensors used to detect whether the station rotation is accurate and whether there is any deviation. Both are connected to a controller.

[0186] The frame 10, as the skeleton of the entire assembly unit, provides necessary physical support and stability. It bears the weight of all components in the unit, including, but not limited to, the turntable body 101, the pressing mechanism 5, the material handling mechanism 9, and various auxiliary devices, ensuring these components are stable and reliable during operation, reducing vibration, and preventing precision loss or equipment damage due to structural instability. The frame 10 is typically designed with a modular concept, facilitating the adjustment or addition of components according to different production needs. For example, new workstations can be easily added to the frame 10, and specific functional modules can be replaced or upgraded. This flexibility enhances the system's adaptability and scalability, reserving space for future production process optimization. The frame 10 also undertakes the orderly arrangement and management of internal electrical wiring, air pipes, hydraulic pipelines, etc., ensuring that these important but easily cluttered elements are safely and neatly integrated, facilitating maintenance and inspection, reducing safety hazards, and improving the safety and aesthetics of the work site. The robust and stable frame 10 design also considers operator safety. Through the installation of guardrails and warning signs, hazardous areas are effectively isolated, preventing accidental contact with moving parts and providing operators with a safer working environment. Whether installed on a workshop floor or integrated with other production lines, the frame 10 can be rationally laid out and adjusted according to actual site conditions, ensuring stable operation of the equipment in different production environments and meeting diverse production needs.

The station lifting head 403 abuts against the support frame 106. The station lifting frame 402 is composed of three rectangular plates missing one side, with the two sides fixed to the base plate and the middle plate fixed to the station lifting cylinder 401.

[0190] Combined with appendix Figure 6 The pressing mechanism 5, configured in conjunction with the pressing station 1010, includes: an independent pressing barrel clamp 503 and a pressing stator clamp 504. Both the pressing barrel clamp 503 and the pressing stator clamp 504 are connected to a pressing clamping guide rail 502. A lead screw is installed within the pressing clamping guide rail 502, and the lead screw is connected to a motor. Both the pressing barrel clamp 503 and the pressing stator clamp 504 are aligned with the pressing station 1010. A sensor is located directly below the pressing barrel clamp 503 and the pressing stator clamp 504. The pressing mechanism 5 is fixed to the base plate via a pressing bracket 501. The pressing bracket 501 includes: multiple upper and lower plates and a column connected to the plates. A pressing cylinder 506 is fixed to the upper plate. The pressing head 505, the pressing barrel clamp 503, and the pressing stator clamp 504 are all located between the plates and are in a straight line.

[0191] Combined with appendix Figure 7The device includes a barrel front mechanism 6, which comprises a barrel front clamp 601, a barrel clamping roller 602, a barrel sensor 603, a barrel bottom clamping drive unit 604, and a barrel bottom gripper 605. The barrel front clamp 601 is located on the side of the barrel, the barrel clamping roller 602 clamps the barrel around its periphery, and the barrel bottom gripper 605 is located at the bottom of the barrel and is arranged in a divergent manner. The barrel bottom clamping drive unit 604 includes a motor and a cylinder. The motor provides rotational drive, and the cylinder controls the opening or closing of the barrel bottom gripper 605. The barrel bottom gripper 605 is connected to a slider, which is located at the end of the cylinder's air passage. When the cylinder draws air, the slider retracts inward, and the barrel bottom gripper 605 clamps. When the cylinder is closed, the barrel bottom gripper 605 loses its clamping force. The barrel clamping roller 602 can rotate, and the barrel can also rotate while clamping the barrel.

[0192] Combined with appendix Figure 8 The stator pre-mounted mechanism 7 is used to rotate the stator. The stator pre-mounted mechanism 7 includes: a stator bottom rotating motor 701, a stator rotating fixture 702, and a stator sensor 703. The stator rotating fixture 702 is connected to the output shaft of the stator bottom rotating motor 701 and is bowl-shaped. The probe of the stator sensor 703 faces the stator. The stator sensor 703 is located on both sides, and the stator bottom rotating motor 701 is fixed to the base plate by a plate.

[0193] Combined with appendix Figure 9The visual inspection mechanism 8 includes a visual drive motor 801, a visual lifting guide rail 802, a visual support 803, and a lens 804. The lens 804 is slidably connected to the visual lifting guide rail 802. A lead screw is provided beside the visual lifting guide rail 802, and the lead screw is connected to the visual drive motor 801. The visual inspection mechanism 8 cooperates with the stator pre-mounted mechanism 7 to detect the rotation angle of the stator. As the core power source, the visual drive motor 801 is responsible for providing the necessary power to drive the lead screw to rotate. By precisely controlling the rotation direction and speed of the motor, the lens 804 in the visual inspection system can be accurately moved up and down to meet the inspection requirements of different heights and viewing angles. This is a linear guide device. The lens 804 slides up and down along this guide rail, ensuring the smoothness and linearity of the lens 804's movement, improving the stability and repeatability of the inspection. The material and design of the guide rail must balance rigidity and wear resistance to support long-term continuous operation without affecting the inspection accuracy. The vision lifting guide rail 802 connects to the rest of the inspection system, providing fixation and support for the lens 804 and ensuring the stability of the entire vision inspection unit. The bracket design needs to consider overall rigidity and coordination with other components for easy adjustment and maintenance. The lens 804 is a key component that directly performs the inspection task, capturing image information from the stator and converting visual signals into digital signals. The quality of the lens 804 directly affects the clarity and accuracy of the inspection; it typically features high resolution, wide-angle, or zoom capabilities to adapt to different inspection requirements and workpiece sizes. The lead screw is connected to the vision drive motor 801, forming a highly efficient linear transmission system. When the motor rotates, the lead screw rotates, engaging with the nut on the guide rail via a thread, enabling precise up-and-down movement of the lens 804. This transmission method features high precision, low noise, and strong load capacity, and is crucial for achieving automatic adjustment of the vision inspection mechanism 8.

[0194] Combined with appendix Figure 10 The unloading and transfer mechanism 9 is located next to the unloading station 1011 and includes: a movable unloading and transfer clamp 903, which is fixed on the unloading sliding seat 902. The unloading sliding seat 902 slides through the unloading guide rail 901, which is equipped with a lead screw and a motor.

[0195] Assembly process:

[0196] ① The barrel is placed on the barrel front mechanism 6 by the robotic arm, and the stator is placed on the stator front mechanism 7. The rotation angle of the barrel and the stator is detected by the sensor and vision inspection mechanism 8. The rotation angle of the barrel and the stator is adjusted to the fitting angle that meets the assembly requirements by the barrel bottom clamping drive 604 and the stator bottom rotating motor 701.

[0197] ②The robotic arm places the barrel at the loading station 108, places the stator on the stator auxiliary fixture 3, moves the stator auxiliary fixture 3 down, places the stator at the barrel opening, and rotates the turntable body 101.

[0198] ③ Fix the barrel and stator by pressing the barrel clamp 503 and pressing the stator clamp 504, start the pressing mechanism 5 to press and assemble the barrel and stator that have been rotated to the pressing station 1010, then rotate the turntable body 101, and the assembled barrel and stator are rotated to the unloading station 1011. Start the station lifting mechanism 4 to push out a certain distance.

[0199] ④ The assembled barrel and stator are removed by the robotic arm and placed in the unloading and transfer mechanism 9 to complete one assembly.

[0200] Example

[0201] Combined with appendix Figure 11 , 12 A water pump rotor bearing assembly device includes: a discharge section 1, a pressing section 2, a left-side loading section 3, a visual inspection section 4, and a right-side loading section 5. A left-side bearing 7, a rotor 8, and a right-side bearing 9 are located on the pressing section 2. All components are located on a base plate. Two discharge sections 1 are provided, arranged side-by-side, to supply bearings for assembly on the left and right sides of the rotor 8, respectively. The left-side loading section 3 is connected to the left side of the left discharge section 1 and the left side of the pressing section 2, and the right-side loading section 5 is connected to the right side of the right discharge section 1 and the right side of the pressing section 2. The left-side loading guide rail 306 of the left-side loading section 3 is perpendicular to the discharge section 1, and the right-side loading guide rail 503 of the right-side loading section 5 is parallel to the discharge section 1. The movement of the right-side loading section 5 perpendicular to the discharge section 1 is achieved by the rotation of the right-side connecting plate 505, as shown in Figures 18 and 20. The pressing section 2 is arranged parallel to the discharge section 1. The vision inspection unit 4 is located on both sides of the left-side feeding guide rail 306. During the feeding process, it detects the orientation of the bearings. Bearings are oriented in different directions, and some bearings (such as angular contact ball bearings) have specific orientation requirements when installed with the rotor 8. The components are distributed rationally and centrally, saving space and reducing the bearing movement distance, thus improving work efficiency.

[0202] Combined with appendix Figure 13 , 14 The discharge section 1 includes: a plurality of feed cylinders 101 arranged in a straight line and a discharge chute 102 disposed along the outlet of the feed cylinders 101. The discharge chute 102 is equipped with a discharge claw 105 for pushing the bearings. The outlet of the feed cylinders 101 is provided with a pusher plate 1012 for uniformly pushing the bearings. In this embodiment, there are 8 feed cylinders 101, and each feed cylinder 101 has an upward-facing opening 103 to facilitate observation of the bearings inside the feed cylinder 101, and the bearings can be moved through the opening 103.

[0203] The feed cylinder 101 is tilted. The gravity of the bearing forms a component force, greatly reducing the pressure on the bottom bearing of the feed cylinder 101. This reduces resistance during the pushing process by the pusher plate 1012, preventing jamming. Furthermore, with the feed cylinder 101 tilted, the bearing exerts pressure on the side wall of the feed cylinder 101, creating friction between the bearing and the feed cylinder 101, thus slowing down the bearing's descent. The top of the opening 103 of the feed cylinder 101 is also provided with a flush inlet for placing the bearing. This inlet facilitates placement, prevents the bearing from easily falling out, and avoids the bearing from flipping inside the feed cylinder 101.

[0204] The outlet of the discharge trough 102 is connected to a discharge port 104, and a material collection point is provided below the discharge port 104 to cooperate with the feeding structure. The discharge port 104 is scoop-shaped, with the smaller opening facing down and the larger opening facing up. After the bearing is removed from the discharge trough 102, it falls through the discharge port 104 to the material collection point below. The material collection point is provided with a pushing mechanism 108 for axially pushing the bearing. The aforementioned pushing mechanism 108 is a cylinder for pushing.

The pusher plate 1012 is fixed to the pusher rod 1013, which passes through the guide seat 109. The guide seat 109 limits the pusher rod 1013, and the reciprocating movement of the pusher rod 1013 drives the pusher plate 1012 to push the bearing. The pusher rod 1013 is connected to a cylinder, which is located below the base plate.

[0206] The discharge claw 105 is L-shaped and covers the width of the discharge trough 102. A protruding claw is located at the lower end of the discharge claw 105, which overlaps the side of the bearing to drive its movement. The discharge claw 105 is fixed to the discharge moving seat 106, which is connected to the discharge screw 107. The discharge moving seat 106 has a threaded hole, and the discharge screw 107 is connected to a discharge drive motor 1010 located on the right side.

The rotating rod 201002 can rotate around the output shaft of the rotating motor 201001, causing the pressure block 201003 to move away. The rotor 8, which was originally limited by the pressure block 201003 above the support block 201004, can now be easily and quickly grasped up and down by the robotic arm after it is moved away. After the rotor 8 without bearings is placed, the rotating rod 201002 is rotated back, and the support block 201004 and the pressure block 201003 form a limiting position.

The barrel angle is adjusted and the barrel and upper bearing seat are pressed at the end face visual alignment mechanism 14. After the adjustment is completed, the barrel is flipped by the robotic arm so that the end faces of the barrel and upper bearing seat face down. The end faces of the barrel and upper bearing seat are located in the middle of the positioning shim pressing mechanism 2 and the screw driving mechanism 3. After starting, the process of pressing the positioning shim and driving the screw is realized. Then, the unloading and conveying mechanism 5 and the unloading and transfer mechanism 15 unload the barrel.

The airtightness testing lifting component 403 presses the oil injection port end face through the airtightness testing head component 402 and connects to the leak meter 14. After air is injected, the leak meter 14 detects the leakage amount and compares it with the maximum allowable leakage amount to determine whether it is qualified. The air outlet pipe of the leak meter 14 is connected to the water pump body 16. Air is blown into the oil injection port through the leak meter 14. The air pressure is 0.43 MPa. The pressure is maintained for a period of time. If the leakage amount is less than 0.016 MPa, it is qualified.

[0251] 3. The rotating clamp 107 clamps the water pump body 16 that has passed the air tightness test to the primary oil injection mechanism 9. The injection gun assembly 901 adjusts the height of the oil injection port through the primary oil injection lifting assembly 903. First, the water pump body 16 is evacuated, and then oil is injected in a metered amount.

[0252] Fourth, move the water pump body 16 to the secondary oil injection mechanism 12, and seal the oil injection port after it overflows.

An assembly method for a fully automated water pump assembly line, characterized in that, Includes the following steps: ① The robotic arm places the barrel onto the barrel pre-positioning mechanism and the stator onto the stator pre-positioning mechanism. Sensors and a vision inspection mechanism detect the rotation angles of the barrel and stator. The rotation angles of the barrel and stator are adjusted to the required fitting angles by the barrel bottom clamping drive and the stator bottom rotating motor. The robotic arm then places the barrel onto the loading station and the stator onto the stator auxiliary fixture. The auxiliary fixture moves down, placing the stator at the barrel opening. The turntable body rotates. The barrel and stator are fixed using the pressing barrel clamp and pressing stator clamp. The pressing mechanism is activated to press and assemble the barrel and stator, which have rotated to the pressing station. Then, the turntable body rotates, and the assembled barrel and stator move to the unloading station. The station lifting mechanism is activated to push them out a certain distance. The robotic arm removes the assembled barrel and stator and places them onto the unloading transfer mechanism for unloading. ② The robotic arm transports the barrel from step ① to the inlet of the water pump rotor bearing assembly device, and quickly discharges the material through the feeding cylinder and discharge chute of the discharge section. Then, the rotor and bearing are pressed and assembled through the pressing section. ③ The robotic arm transports the barrel from step ② to the inlet of the water pump positioning shim screw assembly device. The barrel loading and conveying mechanism loads the barrel, and the barrel is moved by the barrel clamping mechanism and the station shift fork mechanism. The angle of the barrel is adjusted and the barrel and the upper bearing seat are pressed at the end face visual alignment mechanism. After the adjustment is completed, the barrel is flipped by the robotic arm so that the end faces of the barrel and the upper bearing seat are facing down. The end faces of the barrel and the upper bearing seat are located in the middle of the positioning shim pressing mechanism and the screw driving mechanism. After starting, the process of pressing the positioning shim and driving the screw is realized. Then the unloading and conveying mechanism and the unloading and transfer mechanism unload the barrel. ④ The robotic arm transfers the barrel from step ③ to the inlet of the water pump airtightness test oil injection. The water pump body is transferred to the loading and unloading rotating fixture via the loading and unloading transfer fixture. The rotating fixture transfers the water pump body to the vision inspection mechanism and visually aligns the rotation angle of the oil injection hole. The water pump body is rotated to the predetermined angle via the rotating fixture to align the oil injection hole. The rotating fixture takes the water pump body to the airtightness test mechanism. The airtightness test fixture clamps the water pump body. The airtightness test lifting assembly presses the oil injection port end face through the airtightness test head assembly and connects to the leak meter. After air injection, the leak meter detects the leakage amount and compares it with the maximum allowable leakage amount to determine whether it is qualified. The rotating fixture clamps the qualified water pump body after the airtightness test to the primary oil injection mechanism. The filling gun assembly adjusts the height through the primary oil injection lifting assembly to press the oil injection port. First, the water pump body is evacuated, and then oil is injected in a quantitative manner. The water pump body is moved to the secondary oil injection mechanism. After overflowing, the oil injection port is sealed. ⑤ The robotic arm transfers the barrel from step ④ to the inlet of the automated water pump parts assembly device. The barrel is moved by the conveying unit and stops at the oil injection screw mounting part, screw mounting part and oil suction part to install the oil injection screw and screw and perform the oil suction process. ⑥ The robotic arm transfers the barrel from step ⑤ to the inlet of the water pump integrated marking assembly device for laser marking, sandproof sleeve placement, sandproof sleeve pressing, flat pad placement, and rubber sleeve placement. ⑦ The robotic arm transfers the barrel from step ⑥ to the inlet of the pump end parts assembly device. The pump barrel is moved to the pre-tightening pressing mechanism via the barrel transfer mechanism. The rotor is pressed by the pressing head to ensure that the rotor and pump barrel components are assembled in place. The pump barrel, which is clamped on the pressing plate by the robotic arm, is moved to the positioning clamping mechanism. The end cover is adjusted in height by the bottom end cover adjustment mechanism. Then, the adjusting fixture takes the end cover and moves it to the mounting tray. The mounting tray is activated so that the pump barrel and end cover are engaged. The barrel moving mechanism is activated to move the pump barrel to the support plate for screw and washer installation. The screw and washer feeding mechanism takes the screw and washer from the vibratory plate and moves them to the feeding bit. The feeding bit is installed below the support plate. Finally, the pump barrel is moved to the vision positioning detection installation mechanism for vision positioning. The pump barrel is rotated by the installation positioning rotary motor and a probe seat is installed on the top.
