Description

Technical Field

[0001] The present invention relates to the technical field of industrial automated testing, and is particularly suitable for full-parameter automated testing, sorting and labeling of micro air pumps. Background Art

[0002] In the fields of industrial automation and precision manufacturing, micropumps, as core fluid control components, are widely used in medical equipment, electronic cooling, smart homes, and other applications. Their performance parameters (such as pressure, flow, and current stability) directly determine the reliability of end-devices. As market requirements for micropump accuracy and consistency increase, traditional testing methods are no longer able to meet the needs of large-scale production.

[0003] There are many pain points in the current micro pump testing process: First, parameter measurement relies on manual step-by-step operation. Operators need to use pressure gauges, flow meters, multimeters and other tools alternately to measure pressure, flow, and current. A single test requires switching 3-5 types of equipment. The process is cumbersome and time-consuming. The test cycle of a single pump is as long as 2-3 minutes, which is inefficient. Second, manual judgment is easily affected by fatigue and experience differences. The missed detection rate of defective product sorting is as high as 5%-8%. Some hidden defects such as current fluctuations and abnormal pumping time are difficult to identify, resulting in unqualified products flowing into the downstream. Third, the process connection is broken. The pump body that has passed the test needs to be manually transferred to the laser marking machine for marking, and then manually placed in the storage box. The intermediate link not only increases the risk of damage to the pump body due to collisions, but also makes it difficult to improve the overall production rhythm due to the time-consuming transportation.

[0004] Furthermore, existing semi-automatic equipment often only tests a single parameter and requires manual assistance for loading and unloading, as well as switching between states. This prevents a closed loop of the entire "testing-grading-marking-sorting" process. These issues extend production cycles, increase labor costs, and make it difficult to meet the "zero-defect" quality requirements for micropumps in high-end applications. An integrated, fully automated testing solution is urgently needed to overcome these bottlenecks. Summary of the Invention

[0005] The present invention provides a fully automatic intelligent micro pump testing device, which aims to solve the problems of low manual efficiency, step-by-step parameter measurement, high missed detection rate due to manual reliance on defective product sorting, and low degree of process separation automation in existing micro pump testing. The specific invention content is as follows:

[0006] The equipment consists of a rotating turntable, a pump placement station, a testing station, a laser marking station, and a qualified product removal station, all arranged sequentially along the turntable's circumference, as well as a control system that coordinates the operation of these components. The testing station automatically docks finished pumps and tests preset parameters, the laser marking station automatically marks qualified finished pumps, and the qualified product removal station transfers qualified pumps to a designated location. The control system automatically sorts defective products based on test results. This overall structure, through the orderly distribution of various stations and the coordinated control of the control system, automates the entire process from pump placement and parameter testing to marking and sorting, eliminating the need for human intervention and significantly improving testing efficiency and consistency.

[0007] To further describe the above scheme, the test stations include a pressure and load current test station, a flow and no-load current test station, and a pumping time and pumping current test station, which are arranged in sequence. The three test stations are distributed in sequence along the circumference of the turntable. The principle of this step-by-step setting is to assign test tasks to independent stations according to the test requirements of different parameters, so that each station can focus on the precise detection of specific parameters. The effect is to avoid the interference that may be caused by testing multiple parameters at the same time at a single station, improve the accuracy and stability of the test of each parameter, and at the same time, realize the orderly flow of the pump body between different test stations through the rotation of the turntable, ensuring the efficient implementation of the test process.

[0008] Further describing the above scheme, the pressure and load current test station, the flow and no-load current test station, and the pumping time and pumping current test station are all equipped with upper and lower cylinders, front and rear cylinders, a finished product clamping cylinder, a test nozzle cylinder, a test clamping cylinder, a test upper and lower cylinder, a top fixed plate, a lifting plate, a front and rear movable plate, a sleeve, and a guide column. The top fixed plate is fixed to the top of the guide column, and the lifting plate is slidably installed on the guide column through the sleeve. The upper and lower cylinders are fixed to the top fixed plate, and the piston rod is connected to the lifting plate; the front and rear cylinders are fixed under the lifting plate to drive the finished product clamping cylinder to move back and forth; the finished product clamping cylinder is used to clamp the pump body and extract unqualified pump bodies and place them on the defective product tray; the test nozzle cylinder is installed on the bracket, and the test nozzle at the end of its piston rod can be connected to the pump nozzle; the test clamping cylinder is used to clamp the finished pump motor pin to realize power-on testing.

[0009] Its working principle is as follows: the upper and lower cylinders drive the lifting plate to move up and down, driving the relevant components to adjust their height; the front and rear cylinders realize the front and rear position adjustment of the finished product clamping cylinder; the test nozzle cylinder ensures that the test nozzle and the pump nozzle are precisely docked for parameter detection; the test clamping cylinder provides stable contact for power-on testing through the clamping motor pins. Each cylinder works together in the order of "upper and lower cylinders move down → clamp the finished product cylinder → push the test nozzle cylinder forward for docking → clamp the test clamping cylinder for power-on testing → process good and bad products according to the results" to form a complete testing process. The effect of this structure is that through the precise coordination of multiple cylinders, stable clamping of the pump body, precise docking of test components and automated control of the testing process are achieved, ensuring the stability and reliability of the testing process. At the same time, the finished product clamping cylinder can remove bad products in time to avoid affecting subsequent processes.

[0010] Further describing the aforementioned solution, the test station also includes a defective product sorting cylinder, a flip bracket, and a flip cylinder. The piston rods of the front and rear cylinders are connected to the front and rear movable plates, which are slidably mounted on the bottom of the lifting plate. The flip bracket slides underneath the front and rear movable plates via guide rails. The defective product sorting cylinder is fixed to the side of the front and rear movable plates, and its piston rod is connected to the flip bracket. The flip cylinder and flip bracket are mounted on the flip bracket. The flip cylinder drives the flip bracket, which in turn flips the cylinder holding the finished product.

[0011] The principle is as follows: a defective inspection cylinder drives defective pumped finished products to a specific defective tray, while a flip cylinder flips them to match the tray's placement angle. The defective product sorting process is differentiated based on test results: products with pressure, flow, or vacuum defects are placed directly on the first defective tray, while products with current defects are moved backward by the defective inspection cylinder and then downward by the upper and lower cylinders to the second defective tray. This design effectively allows for the categorized placement of defective products, facilitating subsequent analysis and processing. Furthermore, the differentiated sorting process avoids the mixing of different types of defective products, improving the standardization and efficiency of defective product management.

[0012] Further describing the aforementioned solution, the laser marking station includes a laser marking lens, a computerized laser printing switch, and a position alignment component. Its operating principle is as follows: when the control system detects the arrival of a qualified finished pump at the station, it triggers the computerized laser printing switch, and the laser marking lens automatically aligns with the top surface of the finished pump to mark the preset marking content. This structure achieves automatic and precise marking of qualified finished pumps without manual operation, ensuring consistent marking content and accurate marking placement. It also seamlessly integrates with the testing process, improving the overall process continuity.

[0013] To further describe the above scheme, the good product removal station includes good product upper and lower cylinders, good product front and rear cylinders, good product flip cylinders and good product clamping cylinders. Its working principle is as follows: the good product clamping cylinder is used to clamp the qualified pump product, the good product upper and lower cylinders and the good product front and rear cylinders cooperate to realize the lifting and translation of the pump product, and the good product flip cylinder drives the qualified pump product to flip to adapt to the placement angle of the good product tray. Its action sequence is: the good product upper and lower cylinders move down → the good product clamping cylinder clamps → the good product upper and lower cylinders move up to take out the pump body → the good product front and rear cylinders translate → the good product flip cylinder adjusts the angle → the good product upper and lower cylinders move down to place → the good product clamping cylinder releases to let the pump body fall into the good product tray. The effect of this structure is that it can efficiently and smoothly transfer the qualified pump product from the testing station to the good product tray. The coordinated action of each cylinder ensures the accuracy of the transfer process and avoids damage to the qualified pump product. At the same time, adapting to the placement angle of the good product tray ensures the orderly placement of the good products.

[0014] The equipment also includes a good product tray receiving mechanism equipped with a translational drive assembly. Its operating principle is as follows: the translational drive assembly drives the good product tray horizontally, arranging qualified finished pumps at a preset spacing. This design prevents overlapping of qualified pumps on the tray, preventing damage to the pump bodies due to squeezing. Furthermore, the neat arrangement facilitates subsequent storage and handling.

[0015] Further describing the aforementioned solution, the turntable's rotation is achieved by a turntable drive module controlled by a control system. Each rotation of the turntable triggers the sensor at the corresponding workstation. After receiving the sensor signal, each workstation performs testing, marking, or transfer operations according to a preset program, forming a cyclical testing process. The principle is that through the control system's precise control of the turntable's rotation, combined with the sensor's signal transmission, each workstation can be connected and cycled. The effect is to ensure the continuity and rhythm of the entire testing process, allowing each process to be carried out efficiently at a fixed pace, significantly improving the overall operating efficiency of the equipment.

[0016] The control system compares test parameters with standard thresholds, determines whether the finished pump product is acceptable or defective, and triggers the corresponding sorting action. It automatically analyzes and judges the parameter data transmitted from the test station based on preset parameter standards, and then issues action instructions to each actuator. This effectively enables automatic determination of test results and precise triggering of sorting actions, eliminating the subjectivity and errors of manual judgment and improving the accuracy of product grading and the timeliness of sorting.

[0017] In summary, through the coordinated cooperation of various components, the present invention realizes a fully automated process of micro pump placement, multi-parameter testing, automatic grading, laser marking to sorting of good and defective products, effectively improving test efficiency and accuracy, reducing labor costs and defective product missed detection rate, and greatly improving the automation and intelligence level of micro pump testing.

[0036] The above drawings illustrate specific embodiments of the present invention, which will be described in more detail below. These drawings and the accompanying description are not intended to limit the scope of the present invention in any way, but rather to illustrate the concept of the present invention to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] To make the technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0039] See also Figures 1-12 As shown, the equipment takes the full-parameter automated testing of micro air pumps as its core goal. Through a turntable-type multi-station collaborative mechanism, it realizes a full-process closed-loop operation from pump body placement, parameter testing, laser marking to good / bad product sorting.

[0040] The main body of the equipment consists of a rotating turntable 1 system, forming the core flow carrier. The turntable 1 achieves 60° indexing rotation via a turntable drive module 11 (servo motor and precision divider) at the bottom. Six stations are evenly distributed around the circumference, each corresponding to a pump finished product indexing fixture 12. Each time the turntable 1 rotates one grid, a proximity sensor triggers a signal, and each station receives the command and initiates a preset action. The stations are arranged in a circular pattern as follows:

[0041] Pump placement station 2: manually or by a robotic arm, several pump bodies 13 to be tested are placed on the finished pump transfer fixing seat 12;

[0042] Pressure and load current test station 3: detect the working pressure and load current value of the pump body 13;

[0043] Flow and no-load current test station 4: measure gas flow and motor no-load current;

[0044] Pumping time and current test station 5: record the pumping time and current curve of the pumping process;

[0045] Laser marking station 6: automatically marking the qualified pump body 13;

[0046] Good product removal station 7: transfer the qualified pump bodies 13 to the storage area and arrange them to prevent overlapping.

[0047] In this embodiment, the turntable 1 completes a single cycle every 30 seconds and processes multiple pump bodies 13 simultaneously, which is more than 5 times more efficient than traditional manual step-by-step testing.

[0048] Taking the pressure and load current test station 3 as an example (the pressure and load current test station 3, flow and no-load current test station 4, and pumping time and pumping current test station 5 have the same structure), its actuator adopts a three-layer modular design:

[0049] Vertical motion layer: e.g. Figure 5 、 6 As shown in FIG. 7 , four guide posts 386 are vertically fixed to the top of the equipment base 9, and the lifting plate 381 connected to the sleeve 385 can slide along the guide posts 386. The piston rods of the upper and lower cylinders 31 drive the lifting plate 381 up and down to provide a height adjustment basis for testing.

[0050] Horizontal movement layer: The front and rear cylinders 37 are installed horizontally at the bottom of the lifting plate 381, pushing the front and rear moving plates 382 to achieve forward and backward displacement. The defective sorting cylinder 35 is installed at the bottom of the front and rear moving plates 382, ​​pushing the flip bracket 383 to move forward and backward, forming a horizontal telescopic mechanism.

[0051] Execution layer: Figure 8 、 9As shown in , 10, the finished product clamping cylinder 32 is equipped with an adaptive clamping claw to fix the pump body 13 with an adjustable clamping force; the test air nozzle cylinder 33 pushes the test air nozzle 331 to precisely connect with the pump air nozzle 132 to ensure that there is no leakage in the air pressure test; the test upper and lower cylinders 342 drive the test clamping cylinder 34 to move up and down, and the test clamping cylinder 34 controls the copper alloy test chuck 341 to clamp the motor foot 131, and collects current data in real time after power is turned on.

[0052] Defective product sorting differentiation process: When abnormal pressure, flow or pumping parameters are detected, the finished product clamping cylinder 32 cooperates with the upper and lower cylinders 31, the front and rear cylinders 37, and the flip cylinder 36 to place the pump body 13 with abnormal pressure, flow or pumping parameters into the first defective product tray 76;

[0053] If the current parameter exceeds the limit, the defective product inspection cylinder 35 is triggered to move the pump body 13 backward, and the turning cylinder 36 drives the clamp to rotate 90° through the rotating shaft 361, so that the pump body 13 is parallel to the second defective product tray 761 and then falls.

[0054] After the qualified pump body 13 is transferred to the laser marking station 6, the photoelectric sensor triggers the marking instruction:

[0055] The XYZ axis servo module automatically compensates for the pump body's positional deviation of 13±2mm, and the laser marking lens 61 completes focal length calibration within 0.5 seconds; the batch number and grade identification are engraved on the surface of the pump body 13, without any human intervention.

[0056] The good product removal station 7 uses multiple cylinders to ensure the lossless transfer of the pump body 13:

[0057] The good product upper and lower cylinders 71 drive the clamping claws to move downward, and the good product clamping cylinder 74 lightly clamps the pump body 13 in a pressure feedback mode;

[0058] After the gripper rises and removes the pump body 13, the good product front and rear cylinders 72 transfer it horizontally to the top of the good product tray 75. The good product flip cylinder 73 rotates the pump body 13 90° via the rotating shaft 361, turning it parallel to the good product tray 75 before releasing it and placing it. After each row of pump bodies 13 is placed, the translation drive assembly 77 moves the good product tray 75 horizontally by one pump position, ensuring that the rows of pump bodies 13 are aligned and free of squeezing. This mechanism is implemented by a servo motor driving a ball screw, achieving a positioning accuracy of ±0.1mm.

[0059] Equipment operation relies on real-time interaction between the PLC main control module and sensors:

[0060] Data acquisition: Current probe (sampling rate 1kHz), pressure sensor, flow meter, etc. upload test values ​​in real time;

[0061] Parameter determination: The PLC compares the data with the preset threshold (for example, the no-load current standard value is 120±5mA) and triggers the sorting decision tree:

[0062] For example, if the pressure is less than 80 kPa or the flow rate is greater than 5 L / min, mark "pressure / flow rate bad" and classify it into the first bad product tray 76;

[0063] If the pumping time is greater than 10 seconds or the pumping current fluctuation is greater than 15%, mark "poor pumping" and classify it into the first defective tray 76;

[0064] If the load current is greater than 260mA or the no-load current is less than 115mA, mark it as "bad current" and classify it into the second bad product tray 761.

[0065] Otherwise → determine it as good product → transfer to marking station 6.

[0066] Cycle Control: Each time turntable 1 completes a rotation, the PLC resets all cylinder states and initiates the next cycle. Interactive Module 8 displays the test data matrix in real time and supports online adjustment of parameter thresholds.

[0067] In order to have a more thorough and comprehensive understanding of the disclosure of the present invention, the principles thereof are further explained below in conjunction with the usage methods.

[0068] Full process operation example:

[0069] The operator places the first batch of four pump bodies 13, numbered S1-S4, at pump placement station 2. The photoelectric sensor at pump placement station 2 detects that S1-S4 are in place, triggering a signal to the control system, and turntable 1 starts and rotates 60°.

[0070] The first batch of 4 pump bodies 13 are transferred to the pressure and load current test station 3 to detect the working pressure and load current value of the pump body 13; the upper and lower cylinders 31 move downward, driving the lifting plate 381 to be in place, the finished product cylinder 32 clamps the pump body 13, and the test nozzle cylinder 33 pushes forward to make the test nozzle 331 and the pump nozzle 132 accurately dock. At the same time, the upper and lower test cylinders 342 move upward, and the test clamping cylinder 34 drives the copper alloy test chuck 341 to clamp the motor foot 131. Figure 9 As shown, power on the test. The pressure sensor collects data, and the Hall effect current sensor collects load current. If pump bodies 13S1-S4 all pass, the test is complete. The test clamping cylinder 34 is released, the test nozzle cylinder 33 is retracted, and the finished product clamping cylinder 32 is released.

[0071] If the working pressure of pump body S1 is abnormal, the control system determines it as "bad pressure" and triggers the defective product sorting process: the finished product clamping cylinder 32 clamps S1 and releases the pump bodies S2, S3, and S4, the front and rear cylinders 37 drive the rear movement, and the turning cylinder 36 drives the clamping claw to turn 90°. Figure 7 As shown, the upper and lower air cylinders 31 move downward to place the pump body S1 into the first defective product tray 76 .

[0072] If the load current of pump body S2 is abnormal, the control system determines that the load current is bad, and triggers the defective product sorting process: the finished product clamping cylinder 32 clamps S2 and releases the S1, S3, and S4 pump bodies, and the front and rear cylinders 37 drive the pump to move backward. The defective inspection cylinder 35 continues to drive the flip bracket 383 to move backward to the top of the second defective product tray 761, and the flip cylinder 36 drives the clamp to flip 90°. Figure 6 As shown, the upper and lower cylinders 31 move downward to place the pump body 13S2 into the second defective product tray 761, and the other qualified ones are still on the pump finished product transfer fixing seat 12, and move with the turntable 1 to the flow and no-load current test station 4.

[0073] The turntable 1 moves to the flow and no-load current test station 4. If the flow of the pump body 13 is abnormal, the same steps as the aforementioned pressure and load current test station 3 are adopted to place the defective products on the first defective product tray 76; if the no-load current is abnormal, place them on the second defective product tray 761. The qualified products are still on the pump finished product transfer fixed seat 12 and move with the turntable 1 to the exhaust time and exhaust current test station 5.

[0074] After reaching the pumping time and pumping current test station 5, if the pumping time of the pump body 13 is abnormal, it is placed in the first defective product tray 76; if the pumping current is abnormal, it is placed in the second defective product tray 761.

[0075] Qualified pump bodies 13 are transferred to laser marking station 6. A photoelectric sensor triggers the marking command, the visual positioning system detects the position deviation of the pump body 13, and the XYZ axis servo module compensates for the deviation. Laser marking lens 61 is activated, marking the surface of the qualified pump body 13. The visual system then performs a second inspection to check the marking quality.

[0076] After the qualified pump body 13 is printed, it is transferred to the qualified product removal station 7. The qualified product upper and lower cylinders 71 move downward, and the qualified product clamping cylinder 74 clamps the pump body 13. The qualified product front and rear cylinders 72 move horizontally above the qualified product tray 75. The qualified product turning cylinder 73 rotates 90° to make the pump body 13 parallel to the qualified product tray 75. The qualified product upper and lower cylinders 71 move downward to place the pump body 13. The qualified product clamping cylinder 74 releases its gripper, and the translation drive assembly 77 drives the qualified product tray 75 horizontally to reserve space for the next qualified product. This ensures that the qualified product pumps do not overlap when the next rack is raised. This cycle of raising and lowering the racks ensures that qualified products are not squeezed.
