Description

Technical Field

[0001] This utility model relates to an assembly mechanism, specifically a micro water pump eccentric wheel assembly mechanism. Background Technology

[0002] Miniature water pumps, as compact and versatile fluid transport devices, have been widely used in smart homes, medical devices, and cooling systems for new energy vehicles. With the increasing market demand for miniature water pumps, the efficient and precise assembly of their core component, the eccentric wheel, has become a key factor restricting the large-scale development of the industry.

[0003] Traditional eccentric wheel assembly for miniature water pumps relies primarily on manual operation or semi-automatic equipment. Manual assembly requires workers to manually complete steps such as eccentric wheel pickup, angle adjustment, pressing with the pump body, and steel ball installation. This is not only inefficient and unable to meet the demands of large-scale production, but also highly susceptible to human error, resulting in inconsistent assembly precision, unstable product quality, and a high defect rate. While some companies use semi-automatic assembly equipment, which reduces the workload to some extent, issues remain in the eccentric wheel feeding stage. Unstable directional conveying by the vibratory feeder often leads to eccentric wheel accumulation and jamming. Eccentric wheel angle adjustment relies heavily on manual pre-adjustment or simple mechanical positioning, failing to accurately match the actual installation requirements of the pump body. This results in insufficient precision in the fit between the eccentric wheel and the pump body, affecting the pump's operational stability and lifespan. Furthermore, the low automation level of the feeding mechanism during steel ball installation easily leads to misinstallation or omission of steel balls, further reducing assembly efficiency and product qualification rate.

[0007] A vibrating feeder is used to provide an eccentric wheel, the top of which is provided with a shaft hole;

[0008] An eccentric wheel pickup unit includes a first moving device, a rotary cylinder, and a negative pressure suction head.

[0018] Beneficial effects: Strong conveying stability: The pump body rotating conveyor plate on the frame rotates at a uniform speed, which can stably convey the pump bodies to be assembled to the assembly station in sequence, providing a reliable basic platform for subsequent assembly and ensuring the continuity of the assembly process.

[0019] Precise and efficient eccentric wheel picking and moving: The vibrating feeder can arrange the eccentric wheels in an orderly manner and transport them to the designated picking position through directional vibration, which improves the efficiency and orderliness of eccentric wheel feeding.

[0025] The assembly process is highly automated and efficient: the entire assembly process, from pump body conveying, eccentric wheel picking and moving, angle adjustment, installation to steel ball feeding and installation, is completed automatically by each device in coordination. While the pump body rotates the conveyor plate to transport the assembled pump body to the next station, a new pump body to be assembled enters the assembly station.

[0034] Frame 1, on which a pump body rotating conveyor plate is mounted;

[0035] Vibrating feeder 2 is used to provide eccentric wheel 3, the top end of which is provided with shaft hole;

[0036] The eccentric wheel 3 pickup unit includes a first moving device, a rotary cylinder 8 and a negative pressure suction head 9. The first moving device is used to move the negative pressure suction head 9 between the vibrating feeder 2 and the pump body rotating conveyor plate. The rotary cylinder 8 is mounted on the first moving device and drives the negative pressure suction head 9 to rotate.

[0037] CCD camera 10 is positioned above the rotating conveyor plate of the pump body to capture images of the pump body;

[0038] The steel ball feeding unit includes a second moving device and a steel ball feeder 17. The second moving device is used to move the steel ball feeder 17 to the shaft hole position of the eccentric wheel 3.

[0039] The control device controls the rotation of the rotary cylinder 8 based on the image signal collected by the CCD camera 10, so as to adjust the angle of the negative pressure suction head 9, thereby matching the angle of the eccentric wheel 3 with the pump body;

[0040] The eccentric wheel pickup unit presses the eccentric wheel 3 onto the pump body through the negative pressure suction head 9, and the steel ball feeder 17 places the steel balls into the shaft hole of the eccentric wheel 3.

[0041] Frame 1: Frame 1 is the basic support structure of the entire assembly mechanism. A pump body rotating conveyor plate is installed on it to carry and transport the pump body to be assembled, providing a stable working platform for the subsequent assembly of the eccentric wheel 3 and steel balls.

[0042] Vibrating feeder 2: The vibrating feeder 2 adopts a directional vibrating hopper, which can arrange the eccentric wheels 3 in an orderly manner and automatically transport them to the designated pick-up position, ensuring that the eccentric wheels 3 can be stably picked up during the assembly process, improving assembly efficiency and stability. The top of the eccentric wheel 3 is provided with a shaft hole for subsequent installation of steel balls.

[0043] Eccentric wheel 3 pickup unit: The eccentric wheel 3 pickup unit consists of a first moving device, a rotary cylinder 8 and a negative pressure suction head 9.

[0044] The first moving device includes a first transverse slide rail 4, a first transverse slider 5, a first vertical slider 6, and a first transverse cylinder 7. The first transverse slider 5 can slide on the first transverse slide rail 4, and the first vertical slider 6 is connected to the first transverse slider 5 and can slide on it. The first transverse cylinder 7 drives the first transverse slider 5 to move laterally, thereby causing the negative pressure suction head 9 to move laterally between the vibrating feeder 2 and the pump body rotating conveyor plate; at the same time, the setting of the first vertical slider 6 can realize the vertical position adjustment of the negative pressure suction head 9, which is convenient for accurate picking and placing of the eccentric wheel 3.

[0045] Rotary cylinder 8: Installed on the first moving device, it can drive the negative pressure suction head 9 to rotate, thereby adjusting the angle of the eccentric wheel 3 to match the pump body.

[0046] Negative pressure suction head 9: Using the principle of negative pressure adsorption, the eccentric wheel 3 is picked up from the picking position of the vibrating feeder 2, and with the cooperation of the first moving device and the rotary cylinder 8, the eccentric wheel 3 is pressed onto the pump body, thus completing the assembly operation of the eccentric wheel.

[0047] CCD Camera 10: The CCD camera 10 is positioned above the rotating conveyor plate of the pump body, enabling it to capture images of the pump body in real time and transmit the image signals to the control device. The control device analyzes and processes the image signals to obtain relevant information about the pump body, providing data support for the rotary cylinder 8 to adjust the angle of the eccentric wheel 3, thus ensuring precise matching between the eccentric wheel 3 and the pump body.

[0048] Steel ball feeding unit: The steel ball feeding unit consists of a second moving device and a steel ball feeder 17.

[0049] The second moving device includes a second vertical slide rail 11, a second vertical slider 12, a second vertical cylinder 13, a second horizontal slide rail 14, a second horizontal slider 15, and a second horizontal cylinder 16. The second vertical slider 12 can slide on the second vertical slide rail 11 and is driven by the second vertical cylinder 13 to achieve vertical movement. The second horizontal slide rail 14 is fixed to the top of the second vertical slider 12, and the second horizontal slider 15 can slide on the second horizontal slide rail 14 and is driven by the second horizontal cylinder 16 to achieve horizontal movement. Through the coordinated operation of the components of the second moving device, the steel ball feeder 17 can be precisely moved to the shaft hole position of the eccentric wheel 3.

[0050] Steel ball feeder 17: It adopts a vibration or pneumatic feeding method, which can automatically supply and place steel balls into the shaft hole of the eccentric wheel 3 to complete the steel ball assembly operation.

[0051] Control device: The control device includes an image processing module, which receives and analyzes the pump body image signals captured by the CCD camera 10. Through image processing and analysis, the characteristic information of the pump body is obtained, and a control signal is output to the rotary cylinder 8 to achieve precise adjustment of the rotation angle of the eccentric wheel 3, ensuring the assembly accuracy of the eccentric wheel and the pump body.

[0052] Working principle: When this utility model is used, the pump body is transported by the rotating conveyor plate on the frame 1, which carries the pump body to be assembled. The plate rotates at a constant speed and transports the pump body to the assembly station in sequence, providing a stable basic platform for subsequent assembly.

[0053] Eccentric wheel 3 pickup and movement: The vibrating feeder 2 arranges the eccentric wheels 3 in an orderly manner and conveys them to the designated pickup position through directional vibration. The first moving device in the eccentric wheel 3 pickup unit is activated, and the first horizontal cylinder 7 drives the first horizontal slider 5 to slide on the first horizontal slide rail 4, driving the negative pressure suction head 9 to move laterally above the eccentric wheel 3; at the same time, the first vertical slider 6 slides on the first horizontal slider 5, causing the negative pressure suction head 9 to descend to a suitable height. The negative pressure suction head 9 uses the principle of negative pressure adsorption to pick up the eccentric wheel 3 from the vibrating feeder 2, and then the first moving device moves in the opposite direction, moving the eccentric wheel 3 to the assembly station above the pump body rotating conveyor plate.

[0054] Eccentric wheel 3 angle adjustment: When the eccentric wheel 3 is moved above the pump body, the CCD camera 10 captures an image of the pump body and transmits the image signal to the control device. The image processing module in the control device analyzes and processes the image signal to obtain the characteristic information of the pump body and determine the required installation angle of the eccentric wheel 3. Based on the analysis results, the control device outputs a control signal to the rotary cylinder 8, driving the rotary cylinder 8 to rotate the negative pressure suction head 9 and the eccentric wheel 3, adjusting the angle of the eccentric wheel 3 to match the pump body.

[0055] Eccentric wheel 3 installation: After the angle of eccentric wheel 3 is adjusted, the first vertical slider 6 drives the negative pressure suction head 9 to descend, pressing the eccentric wheel 3 onto the pump body, thus completing the installation operation of the eccentric wheel.

[0056] Ball Feeding and Installation: After the eccentric wheel 3 is installed, the second moving device of the ball feeding unit begins to operate. The second vertical cylinder 13 drives the second vertical slider 12 to slide on the second vertical slide rail 11, causing the ball feeder 17 to descend to a suitable height. Then, the second horizontal cylinder 16 drives the second horizontal slider 15 to slide on the second horizontal slide rail 14, precisely moving the ball feeder 17 to the shaft hole position of the eccentric wheel 3. The ball feeder 17 uses a vibration or pneumatic feeding method to automatically supply and place the ball feeders into the shaft hole of the eccentric wheel 3, completing the ball assembly operation. At this point, the assembly process of a miniature water pump eccentric wheel is completed. The pump body rotating conveyor plate transports the assembled pump body to the next station, while a new pump body to be assembled enters the assembly station, repeating the above assembly process.

[0057] Beneficial effects: Strong conveying stability: The pump body rotating conveyor plate on frame 1 rotates at a uniform speed, which can stably convey the pump bodies to be assembled to the assembly station in sequence, providing a reliable basic platform for subsequent assembly and ensuring the continuity of the assembly process.

[0058] The eccentric wheel 3 is precise and efficient in picking up and moving: the vibrating feeder 2 can arrange the eccentric wheel 3 in an orderly manner and transport it to the designated picking position through directional vibration, which improves the efficiency and orderliness of the eccentric wheel 3 feeding.

[0059] The first moving device in the eccentric wheel 3 picking unit drives the first horizontal slider 5 to slide on the first horizontal slide rail 4 through the first horizontal cylinder 7, and the first vertical slider 6 to slide on the first horizontal slider 5, realizing the horizontal and vertical movement of the negative pressure suction head 9. It can accurately pick up the eccentric wheel 3 from the vibrating feeder 2 and move it to the assembly station above the pump body rotating conveyor plate, ensuring the accuracy and efficiency of the eccentric wheel 3 picking and moving.

[0060] Precise adjustment of the eccentric wheel 3 angle: When the eccentric wheel 3 is moved above the pump body, the CCD camera 10 captures the pump body image and transmits it to the control device. The image processing module of the control device analyzes the image signal to obtain the pump body feature information, thereby determining the required installation angle of the eccentric wheel 3. Then, by controlling the rotary cylinder 8 to drive the negative pressure suction head 9 and the eccentric wheel 3 to rotate, the angle of the eccentric wheel 3 is precisely matched with the pump body, ensuring the accuracy of the installation angle of the eccentric wheel 3 and improving the assembly quality.

[0061] The eccentric wheel 3 is easy to install: After the angle of the eccentric wheel 3 is adjusted, the first vertical slider 6 drives the negative pressure suction head 9 to descend, pressing the eccentric wheel 3 onto the pump body. The operation is simple and the installation of the eccentric wheel 3 can be completed quickly.

[0062] The steel ball feeding and installation are highly automated: the second moving device of the steel ball feeding unit drives the second vertical slider 12 to slide on the second vertical slide rail 11 through the second vertical cylinder 13, and drives the second horizontal slider 15 to slide on the second horizontal slide rail 14 through the second horizontal cylinder 16, so as to accurately move the steel ball feeder 17 to the shaft hole position of the eccentric wheel 3.

[0063] The steel ball feeder 17 adopts a vibration or pneumatic feeding method, which can automatically supply steel balls and place them into the shaft hole of the eccentric wheel 3, realizing the automation of steel ball feeding and installation, improving assembly efficiency and reducing manual operation.

[0064] The assembly process is highly automated and efficient: the entire assembly process, from pump body conveying, eccentric wheel 3 picking up and moving, angle adjustment, installation to steel ball feeding and installation, is completed automatically by each device in coordination. While the pump body rotates the conveyor plate to transport the assembled pump body to the next station, a new pump body to be assembled enters the assembly station. The above assembly process can be repeated, which greatly improves assembly efficiency, reduces labor costs, and is suitable for large-scale production.
