[0002] In the manufacturing process of water pumps, the triangular valve plate is a key component, and its assembly quality with the workpiece directly affects the overall performance and service life of the water pump. Traditional water pump triangular valve plate assembly processes often employ manual assembly. Manual assembly is not only inefficient and unable to meet the demands of large-scale production, but it is also greatly affected by factors such as worker skill level and working conditions, resulting in inconsistent assembly precision, poor product quality stability, and increased defect rates and production costs.

[0003] With the widespread application of automation technology in manufacturing, some companies have begun to try using automated equipment for assembling triangular valve plates. However, existing automated assembly equipment generally suffers from problems such as complex structure, difficult debugging, and high cost. Although some equipment can achieve basic assembly functions, it lacks effective technical means in the position adjustment of the triangular valve plates, making it difficult to accurately control the angle of the valve plates, resulting in assembled products that cannot meet high-precision usage requirements.

Detailed Implementation

[0039] The following is in conjunction with the appendix Figure 1-6 The specific embodiments of this utility model will be described in further detail.

[0040] Example 1, by Figure 1-6 This utility model provides a water pump triangular valve plate assembly mechanism, comprising:

[0041] Rack 1;

[0042] The column 2 is fixed on the frame 1;

[0043] The vibrating feeder 3, located on both sides of the column 2, is used to convey the triangular valve plate 4;

[0044] The horizontal slide rail 6 is installed at the top of column 2;

[0045] The horizontal slider 7 is slidably connected to the horizontal slide rail 6;

[0046] A transverse cylinder 8 drives the transverse slider 7;

[0047] A vertical cylinder 9 is mounted on the horizontal slider 7;

[0048] A vertical slide plate 10 connected to the output end of the vertical cylinder 9;

[0049] A crossbeam 11 is fixed to the bottom of the vertical slide plate 10;

[0050] The negative pressure suction head 12 located at the bottom of the crossbeam 11 is used to adsorb the triangular valve plate 4;

[0051] Adjustment column 13 located on the moving path of negative pressure suction head 12;

[0052] Rotary cylinder 14 drives the adjustment column 13 to rotate;

[0053] The workpiece 5 to be assembled is located below the negative pressure suction head 12;

[0054] The negative pressure suction head 12 transfers the triangular valve plate 4 conveyed by the vibrating feeder 3 to the adjusting column 13 for position adjustment, and then assembles it onto the workpiece 5 to be assembled.

[0055] Frame 1 and Column 2: Frame 1 provides a stable supporting foundation for the entire assembly mechanism, ensuring the stability of the equipment during operation. Column 2 is fixed to frame 1 and serves as a supporting structure for the installation of other components, providing installation positions for components such as the vibrating feeder 3 and the transverse slide rail 6.

[0056] Vibrating feeder 3: Adopting a directional vibrating plate design, it can automatically arrange and convey the triangular valve plates 4 in an orderly manner. Its discharge end is equipped with a single-piece separation mechanism, which can ensure that only one triangular valve plate 4 is output at a time, avoiding the chaos caused by multiple plates being output at the same time, and providing a guarantee for subsequent accurate grasping.

[0057] Horizontal slide rail 6, horizontal slider 7, and horizontal cylinder 8: The horizontal slide rail 6 is installed at the top of the column 2, and the horizontal slider 7 is slidably connected to the horizontal slide rail 6. The horizontal cylinder 8 drives the horizontal slider 7 to make horizontal linear motion on the horizontal slide rail 6, thereby driving the vertical cylinder 9 connected to the horizontal slider 7 and related components to move horizontally, realizing the horizontal position adjustment of the negative pressure suction head 12.

[0058] Vertical cylinder 9, vertical slide plate 10, and crossbeam 11: Vertical cylinder 9 is mounted on horizontal slider 7, and its output end is connected to vertical slide plate 10. Vertical cylinder 9 drives vertical slide plate 10 to move vertically through extension and retraction, thereby driving crossbeam 11 and negative pressure suction head 12, which are fixed to the bottom of vertical slide plate 10, to move up and down, completing the gripping and placement action of triangular valve plate 4. Horizontal cylinder 8 and vertical cylinder 9 operate synchronously through air circuit linkage controller, enabling precise coordinated movement of negative pressure suction head 12 in both horizontal and vertical directions.

[0059] Negative pressure suction heads 12: There are two of them, symmetrically distributed on both sides of the bottom center line of the crossbeam 11, used to adsorb the triangular valve plate 4. Through negative pressure suction, the triangular valve plate 4 can be stably gripped and its position can be kept fixed during movement, ensuring the accuracy of assembly.

[0060] Adjustment column 13 and rotary cylinder 14: The adjustment column 13 is located on the moving path of the negative pressure suction head 12, and has an elastic clamping part at the top. Its circumferential sidewall has a positioning groove that matches the contour of the triangular valve plate 4. The rotary cylinder 14 drives the adjustment column 13 to rotate. When the negative pressure suction head 12 transfers the triangular valve plate 4 to the adjustment column 13, the elastic clamping part fixes the triangular valve plate 4 in the positioning groove. The rotary cylinder 14 can adjust the position of the triangular valve plate 4 to achieve the correct angle suitable for assembly.

[0061] CCD vision sensor: Located above the adjustment column 13, it is used to detect the rotation angle of the triangular valve plate 4. Through real-time monitoring, it can accurately provide feedback on the position and posture information of the triangular valve plate 4, providing data support for the adjustment action of the rotating cylinder 14 and ensuring the accuracy of the position and posture adjustment.

[0062] Workpiece 5 to be assembled: Located below the negative pressure suction head 12, it is the assembly target of the triangular valve plate 4. The negative pressure suction head 12 accurately assembles the triangular valve plate 4, which has been adjusted in position, onto the workpiece 5 to be assembled, thus completing the assembly process.

[0063] Working Principle: During the feeding stage of this invention: After starting the equipment, the vibrating feeder 3 begins operation. As a directional vibrating plate, it utilizes the principle of vibration to cause the triangular valve plates 4 placed within it to move continuously within a specific track. During this movement, the triangular valve plates 4 are gradually arranged in an orderly manner due to the influence of vibration and the track shape. The discharge end triangular valve plate 4 reaches the designated discharge position, laying the foundation for subsequent precise grasping.

[0064] Grasping and Transfer Stage: The horizontal cylinder 8 and the vertical cylinder 9 work in concert via a pneumatic linkage controller. The horizontal cylinder 8 drives the horizontal slider 7 to move horizontally in a straight line on the horizontal slide rail 6, which in turn drives the vertical cylinder 9 and its connected components to move horizontally. The vertical cylinder 9 drives the vertical slide plate 10 and the crossbeam 11 to move up and down through its extension and retraction. Together, these two components move the negative pressure suction head 12 precisely to the discharge position of the vibrating feeder 3. At this time, the negative pressure suction head 12 activates its negative pressure suction, stably adsorbing the single triangular valve plate 4. Subsequently, under the linkage of the horizontal cylinder 8 and the vertical cylinder 9, the negative pressure suction head 12, carrying the triangular valve plate 4, moves along a specific trajectory to above the adjusting column 13.

[0065] Positioning adjustment stage: The negative pressure suction head 12 descends, placing the triangular valve plate 4 on top of the adjusting column 13. The elastic clamping part at the top of the adjusting column 13, relying on its own elasticity, firmly fixes the triangular valve plate 4 in the positioning groove that matches the contour of the triangular valve plate 4 on the circumferential side wall. At this time, the CCD vision sensor located above the adjusting column 13 starts working, detecting the rotation angle of the triangular valve plate 4 in real time and transmitting the detected angle data to the control system. The control system calculates the angle difference that needs to be adjusted according to the preset assembly angle requirements, and then sends a command to the rotating cylinder 14. After receiving the command, the rotating cylinder 14 drives the adjusting column 13 to rotate, causing the triangular valve plate 4 to rotate to the correct position, ensuring that its angle meets the requirements for assembly with the workpiece 5 to be assembled.

[0066] Assembly Stage: After the orientation adjustment is completed, the negative pressure suction head 12 descends again to adsorb the triangular valve plate 4. Then, driven by the combined action of the horizontal cylinder 8 and the vertical cylinder 9, it moves to directly above the workpiece 5 to be assembled. Subsequently, the vertical cylinder 9 drives the negative pressure suction head 12 to descend, accurately placing the orientation-adjusted triangular valve plate 4 at the designated assembly position on the workpiece 5, completing one assembly process. Afterward, the negative pressure suction head 12 rises, returning to the discharge position of the vibrating feeder 3, and repeats the above feeding, gripping, transferring, orientation adjustment, and assembly steps to achieve continuous automated assembly of the triangular valve plate 4.

[0067] Beneficial effects: Vibrating feeder 3 achieves automatic and orderly arrangement: Utilizing the principle of vibration and a specific track design, the triangular valve plates 4 automatically complete the orderly arrangement during movement without manual intervention, thus improving feeding efficiency.

[0068] Precise material discharge positioning: The discharge end of the vibrating feeder 3 can accurately deliver the triangular valve plate 4 to the designated position, providing a stable foundation for subsequent gripping actions and reducing positioning errors.

[0069] Coordinated motion of air circuit linkage control: The horizontal cylinder 8 and the vertical cylinder 9 cooperate through the air circuit linkage controller to drive the horizontal slider 7 to make horizontal linear motion on the horizontal slide rail 6, and drive the vertical cylinder 9 and connected components to move horizontally; at the same time, the vertical cylinder 9 drives the vertical slide plate 10 and the crossbeam 11 to move up and down through the extension and retraction action, so as to realize the precise movement of the negative pressure suction head 12 in the horizontal and vertical directions and ensure the accuracy of the gripping position.

[0070] Stability of negative pressure adsorption: The negative pressure suction head 12 stably adsorbs the single triangular valve plate 4 through negative pressure suction, avoiding displacement or falling during the gripping process and ensuring the reliability of the transfer process.

[0071] Precise fixing of elastic clamping and positioning groove: The elastic clamping part at the top of the adjusting column 13 and the positioning groove that matches the contour can firmly fix the triangular valve plate 4 to the circumferential side wall, ensuring that the position remains unchanged during the testing and adjustment process.

[0072] CCD visual inspection and automatic angle adjustment: The CCD visual sensor located above the adjustment column 13 detects the angle data of the triangular valve plate 4 in real time. Combined with the control system and the rotating cylinder 14, it realizes automatic angle correction, ensuring the matching accuracy between the position of the triangular valve plate 4 and the workpiece 5 to be assembled, avoiding the errors and time consumption of manual adjustment.

[0073] Full-process automated collaboration: The negative pressure suction head 12, horizontal cylinder 8, and vertical cylinder 9 are linked with the control system to realize full-process automation from gripping, transferring, and position adjustment to assembly, reducing manual operation and improving production efficiency.

[0074] Continuous operation capability: After completing a single assembly, the negative pressure suction head 12 automatically returns to the discharge position of the vibrating feeder 3 to repeat the operation, realizing the continuous assembly of the triangular valve plate 4, which is suitable for mass production scenarios and reduces production costs.
