Description

Technical Field

[0001] This utility model relates to a reaction vessel, specifically a cylinder orientation mechanism for a micro water pump assembly device. Background Technology

[0002] In the automated assembly process of miniature water pumps, the cylinder body, as a core component, directly affects the connectivity of the internal fluid channels and the overall performance of the pump due to the positional accuracy of its circumferential through-holes. Therefore, the cylinder body must be precisely oriented before entering the assembly process to ensure that the position of the through-holes is strictly aligned with the installation positions of subsequent components (such as impellers, seals, etc.).

[0003] Inadequacy of existing technology

[0004] Manual orientation is inefficient and has inconsistent accuracy.

[0005] In traditional assembly processes, cylinder block orientation largely relies on manual operation, involving visually identifying the positions of through holes and manually adjusting the orientation. This method has the following drawbacks:

[0006] Inefficient: Manually adjusting the direction of each cylinder is difficult to match the high-speed cycle requirements of automated production lines;

[0007] Large fluctuations in accuracy: Due to the subjective judgment of the operator, the position of the through hole is prone to deviation, which can lead to problems such as misalignment and sealing failure during subsequent assembly, increasing the defect rate.

[0008] Traditional mechanical orientation mechanisms lack versatility

[0009] Some automated equipment uses mechanical shift forks, slots, and other structures to achieve cylinder orientation, but such methods have significant limitations.

[0010] The detection and control logic is simple.

[0011] Existing detection methods mostly employ mechanical limits or simple photoelectric switches, which can only determine whether the cylinder is in position and cannot accurately identify the circumferential position of the through hole. For example, traditional photoelectric detection cannot distinguish the different angles of the through hole during cylinder rotation, leading to orientation failure or the need for repeated adjustments, thus reducing production efficiency. Utility Model Content

[0012] In view of the above situation and to overcome the defects of the prior art, this utility model provides a cylinder orientation mechanism for a micro water pump assembly device, which effectively solves the problems mentioned in the background art.

[0014] Feeding track, used to transport cylinders with at least one through hole in the circumference;

[0015] Detection components, including:

[0016] A support bracket is provided at the discharge end of the feeding track;

[0017] The detection disc is rotatably mounted on the bracket, and has a detection hole in its middle with a diameter smaller than the outer diameter of the cylinder body. The position of the detection hole corresponds to the movement trajectory of the cylinder body through hole.

[0018] An infrared transmitter and an infrared receiver are respectively located above and below the detection hole;

[0019] The rotary drive unit includes a rotary motor mounted on the bracket, the rotary motor being connected to the detection disk in a transmission manner;

[0020] The control module, electrically connected to the infrared receiver and the rotating motor, is configured as follows:

[0021] When the infrared receiver continuously receives infrared signals, it controls the rotating motor to drive the detection disk to rotate.

[0022] When the infrared receiver first interrupts receiving the infrared signal due to the blockage of the infrared signal by the cylinder through-hole wall, the control motor stops rotating to complete the cylinder orientation.

[0023] Preferably, the number of detection holes is one, and its diameter is smaller than the outer diameter of the cylinder body.

[0024] Preferably, it also includes a first pneumatic clamp located at the discharge end of the feeding track, used to remove the cylinder body from the feeding track before testing.

[0025] Preferably, the control module is further configured to: trigger the clamping unit to transfer the cylinder that has completed orientation after the rotating motor stops.

[0026] Preferably, the clamping unit includes multiple arrayed second pneumatic clamps and a cylinder slide rail assembly for driving the three-dimensional movement of the second pneumatic clamps.

[0027] Preferably, the center of the detection hole of the detection disc is coaxial with the cylinder axis.

[0028] Beneficial effects: Precise detection and orientation, ensuring assembly accuracy: The detection holes of the detection plate correspond to the movement trajectory of the cylinder block through holes, and the center is coaxial with the cylinder block axis. With the signal detection of the infrared transmitter and receiver, the position of the cylinder block through holes can be accurately identified.

[0029] The control module analyzes the timing of infrared signal interruptions and controls the start and stop of the rotating motor to ensure that the cylinder automatically stops rotating when the through hole reaches the target position, achieving high-precision orientation, avoiding manual adjustment errors, and improving assembly consistency.

Detailed Implementation

[0039] The following is in conjunction with the appendix Figure 1-7 The specific embodiments of this utility model will be described in further detail.

[0040] Example 1, by Figure 1-7 The present invention provides a cylinder orientation mechanism for a micro water pump assembly equipment, comprising: a feeding track 3 for conveying a cylinder 4 having at least one through hole in the circumferential direction;

[0041] Detection components, including:

[0042] The bracket 12 is located at the discharge end of the feeding track 3;

[0043] The detection plate 13 is rotatably mounted on the bracket 12, and has a detection hole in its middle with a diameter smaller than the outer diameter of the cylinder 4. The position of the detection hole corresponds to the movement trajectory of the through hole of the cylinder 4.

[0044] An infrared transmitter 14 and an infrared receiver are respectively located above and below the detection hole;

[0045] The rotary drive unit includes a rotary motor 16 mounted on the bracket 12, and the rotary motor 16 is connected to the detection disk 13 in a transmission manner;

[0046] The control module, electrically connected to the infrared receiver and the rotating motor 16, is configured as follows:

[0047] When the infrared receiver continuously receives infrared signals, it controls the rotating motor 16 to drive the detection disk 13 to rotate.

[0048] When the infrared receiver first interrupts receiving the infrared signal due to the infrared signal being blocked by the through hole wall of cylinder 4, the control motor 16 stops rotating to complete the orientation of cylinder 4.

[0049] Chassis 1: Chassis 1 provides a stable mounting base and support frame for the entire orientation mechanism and serves as the carrier for mounting other components.

[0050] Vibrating feeding plate 2: The vibrating feeding plate 2 is installed on one side of the top of the machine box 1. Through vibration, the cylinder 4 placed inside it is arranged in an orderly manner and transported to the feeding track 3 to realize the automatic feeding of the cylinder 4.

[0051] Feeding track 3: The feeding track 3 is installed at the discharge port of the vibrating feeding plate 2 to receive the cylinder 4 conveyed by the vibrating feeding plate and transport it along the track to the subsequent processing position.

[0052] Horizontal slide rail 5 and horizontal cylinder 6: The horizontal slide rail 5 is installed on the top of the housing 1, and the horizontal cylinder 6 is fixedly installed on one end of the horizontal slide rail 5. The horizontal slider 7 is laterally slidably connected to the horizontal slide rail 5, and one end is connected to the free end of the horizontal cylinder 6. The horizontal cylinder 6 drives the horizontal slider 7 to slide on the horizontal slide rail 5, realizing the lateral movement of the relevant components.

[0053] Vertical cylinder 8 and slider 7: Vertical cylinder 8 is fixedly installed at the top of horizontal slider 7, and vertical slider 9 is vertically slidably connected to one side of horizontal slider 7, with its top end fixed to the free end of vertical cylinder 8. Vertical cylinder 8 drives vertical slider 9 to slide in the vertical direction, realizing the vertical movement of the component.

[0054] First pneumatic clamp 10: The first pneumatic clamp 10 is installed on one side of the discharge port of the feeding track 3 and is used to remove the cylinder 4 in the feeding track 3 before testing, and cooperate with the moving cylinder 11 to realize the clamping and transfer of the cylinder.

[0055] Moving cylinder 11: The moving cylinder 11 is installed on one side of the first pneumatic clamp 10 and fixed to the transverse slide rail 5. It can drive the first pneumatic clamp 10 to move in the horizontal direction to realize the transfer of the cylinder body 4 between different work positions.

[0056] Second pneumatic clamp 15: Multiple second pneumatic clamps 15 are equidistantly arrayed at the bottom of the vertical slider 9 to form a clamping unit, which is used to clamp the cylinder 4 that has been oriented and move in three dimensions under the drive of the cylinder slide rail assembly to transfer the cylinder to the subsequent assembly station.

[0057] Support 12: The support 12 is installed on the housing 1 at the bottom of the feeding track 3 to provide installation support for the detection plate 13 and other detection components.

[0058] Detection plate 13: The detection plate 13 is rotatably mounted on the bracket 12. A detection hole is opened in the middle. The inner diameter of the detection hole is smaller than the outer diameter of the cylinder 4. The detection hole is located outside the through hole of the cylinder 4. Its center is coaxial with the axis of the cylinder 4. It is used to perform orientation detection on the cylinder 4.

[0059] Infrared transmitter 14 and receiver: The infrared transmitter 14 is mounted on the bracket 12 above the detection hole, and the infrared receiver is mounted on the bracket 12 below the detection hole. The two work together to detect the position of the cylinder 4 through hole so as to achieve the orientation of the cylinder.

[0060] Rotary motor 16: Rotary motor 16 is installed on one side of bracket 12 and is connected to detection disk 13 for transmission. The detection disk 13 is driven to rotate by rotating motor 16, thereby driving cylinder 4 placed on detection disk to rotate, realizing direction selection operation.

[0061] Control Components: The control module is electrically connected to the infrared receiver and the rotating motor 16. It is the control core of the entire orientation mechanism. By processing the infrared receiver signal, it controls the start and stop of the rotating motor 16 to achieve the orientation and positioning of the cylinder 4. After orientation is completed, it triggers the clamping unit to transfer the cylinder 4.

[0062] Working Principle: In the automatic feeding stage of this invention: The vibrating feeding plate 2 is installed on one side of the top of the machine housing 1. After being turned on, it uses its own vibration to arrange the randomly placed cylinders 4 inside into an orderly manner. Subsequently, the orderly arranged cylinders 4 are conveyed to the feeding track 3 connected to the discharge port of the vibrating feeding plate 2, realizing the automatic feeding of the cylinders 4. After receiving the cylinders 4, the feeding track 3 smoothly conveys them to the subsequent processing position along the track, awaiting further operation.

[0063] Cylinder body transfer to the inspection station: When cylinder body 4 is conveyed to the discharge port of feeding track 3, the first pneumatic clamp 10 located on one side of the discharge port is activated, using its pneumatic clamping function to remove cylinder body 4 from the feeding track 3. At the same time, the moving cylinder 11 connected to the first pneumatic clamp 10 starts working, driving the first pneumatic clamp 10 to move in the horizontal direction, transferring the clamped cylinder body 4 to the designated position above the inspection plate 13.

[0064] Horizontal and vertical movement adjustment: The horizontal movement assembly, consisting of the horizontal slide rail 5 and the horizontal cylinder 6, and the vertical movement assembly, consisting of the vertical cylinder 8 and the vertical slider 9, function as follows: The horizontal cylinder 6 drives the horizontal slider 7 to slide on the horizontal slide rail 5, thereby adjusting the position of the relevant components in the horizontal direction; the vertical cylinder 8 drives the vertical slider 9 to slide in the vertical direction, so that the cylinder 4 reaches the appropriate height in the vertical direction, ensuring that the cylinder 4 can be accurately placed on the detection plate 13.

[0065] Detection and Orientation Stage: The cylinder 4 is placed on the detection plate 13. The position of the detection hole in the middle of the detection plate 13 corresponds to the movement trajectory of the through hole of the cylinder 4, and the inner diameter of the detection hole is smaller than the outer diameter of the cylinder 4, with its center coaxial with the axis of the cylinder 4. The infrared transmitter 14 mounted on the bracket 12 above the detection hole and the infrared receiver mounted on the bracket 12 below the detection hole begin to work, working together to detect the position of the through hole of the cylinder 4. When the infrared receiver continuously receives the infrared signal emitted by the infrared transmitter 14, it indicates that the through hole of the cylinder 4 is not in the correct position. The control module electrically connects the infrared receiver and the rotating motor 16, controlling the rotating motor 16 to drive the detection plate 13 to rotate, causing the cylinder 4 to rotate as well. When the infrared receiver first interrupts receiving the infrared signal due to the infrared signal being blocked by the wall of the through hole of the cylinder 4, it indicates that the through hole of the cylinder 4 is in the target position. The control module controls the rotating motor 16 to stop rotating, completing the orientation operation of the cylinder 4.

[0066] Cylinder body transfer to assembly station: After the cylinder body 4 is oriented, multiple second pneumatic clamps 15, equidistantly arrayed at the bottom of the vertical slider 9, form a clamping unit to clamp the oriented cylinder body 4. Subsequently, driven by the cylinder slide rail assembly consisting of the transverse slide rail 5, the transverse cylinder 6, and the vertical cylinder 8, the second pneumatic clamps 15 move the cylinder body 4 in three dimensions, precisely transferring the cylinder body 4 to the subsequent assembly station for the next step of micro water pump assembly.

[0067] Beneficial effects: Precise detection and orientation, ensuring assembly accuracy: The detection holes of the detection plate 13 correspond to the movement trajectory of the through holes of the cylinder 4, and the center is coaxial with the cylinder axis. With the signal detection of the infrared transmitter 14 and receiver, the position of the cylinder through holes can be accurately identified.

[0068] The control module analyzes the timing of infrared signal interruption and controls the start and stop of the rotating motor 16 to ensure that the cylinder 4 automatically stops rotating when the through hole reaches the target position, achieving high-precision orientation, avoiding manual adjustment errors, and improving assembly consistency.
