Second, manual testing is inefficient, with long testing times per unit, making it difficult to meet the cycle time requirements of large-scale production, and labor costs are high. Third, existing testing equipment lacks a robust positioning mechanism and safety protection devices, making it prone to distorted test results due to product positioning deviations, and also presenting operational safety issues. Finally, test data requires manual recording and organization, and cannot be displayed in real time or automatically judged for pass / fail status, hindering quality traceability and big data analysis, and is prone to data recording errors and omissions.

[0023] A rotary motor 651 is fixedly mounted on the mounting plate 65. One end of an extension plate 6511 is fixedly connected to the drive end of the rotary motor 651. The pressure sensor 3 is fixedly mounted on the other end of the extension plate 6511. The pressure sensor 3 is driven by the rotary motor 651 to achieve a toggle angle conversion.
[0024] Multiple positioning rods 451 are fixedly provided on the positioning plate 45, and multiple positioning holes 211 are provided on the carrier plate 21 that correspond one-to-one with each positioning rod 451 and can form an insertion fit. The carrier plate 21 forms an installation positioning on the positioning plate 45 through the insertion fit between each positioning rod 451 and each positioning hole 211.
[0025] The carrier plate 21 is also fixedly equipped with a laser displacement sensor 9 for detecting whether the air outlet product is placed on the positioning seat 22, and the frame 1 is also fixedly equipped with a barcode printer 11 for printing the force measurement results.
[0026] The PLC used is from Huichuan, the industrial computer is from Tuolang, the laser displacement sensor 9 is from Boyi Precision Technology, and the Z-axis servo motor 64, X-axis servo motor 55 and Y-axis servo motor 44 are all from Panasonic.
[0027] The frame 1 is also equipped with a PLC, an industrial computer, and a display screen 12. The PLC is fixedly mounted on the frame 1 and is used to drive the Y-axis moving assembly 4, the X-axis moving assembly 5, and the Z-axis moving assembly 6 to work. The industrial computer has an input terminal and an output terminal. The input terminal of the industrial computer is electrically connected to the pressure sensor 3 and the toggle position detection sensor 23, respectively. The output terminal of the industrial computer is electrically connected to the PLC, the display screen 12, and the barcode printer 11, respectively. The display screen 12 is fixedly mounted on the frame 1 and is used to display the test results.
[0028] The air circuits of each pressing cylinder 24 are connected in parallel and controlled by a unified solenoid valve group. The solenoid valve group receives a switching signal from the PLC. When the laser displacement sensor 9 detects that the product has been placed in place, the PLC sends a signal, the solenoid valve is turned on, and compressed air enters all pressing cylinders 24 at the same time, driving all pressing plates 7 to move synchronously to complete the pressing or releasing. Furthermore, pressure regulating valves and throttle valves can be provided in the air circuit to adjust the magnitude of the pressing force and the speed of the pressing plate 7 movement to achieve flexible clamping.
[0029] In this example, the PLC uses Huichuan brand as the lower-level control core, responsible for the action logic control of all actuators, including: start / stop, speed and position control of Y-axis, X-axis and Z-axis servo motors 64 (in this example, Panasonic brand is used); angle control of rotary motor 651; and on / off control of solenoid valve of pressure cylinder 24. In this example, the industrial computer uses Tuolang brand as the upper-level computer, responsible for data processing and human-machine interaction. The industrial computer receives the force value signal from pressure sensor 3 and the position signal from toggle position detection sensor 23, such as micro switch or photoelectric sensor, in real time through data acquisition card or communication interface. The detection signal from laser displacement sensor 9 (in this example, Boyi Precision Technology brand is used) is also sent to the PLC as an interlock condition for equipment start-up.
[0030] The pressure sensor 3 in this application has the following detection range: vertical force 0-50N, horizontal force 0-30N, and detection accuracy ±0.01N.
[0031] During the testing process, the industrial control computer plots "force-displacement" or "force-time" curves in real time, automatically calculates characteristic values such as peak force, rebound force, and friction force, and compares them with preset upper and lower limits of pass. The "pass / fail" conclusion and detailed data are displayed on the display screen 12 in real time. At the same time, the industrial control computer can control the barcode printer 11 to print labels containing product model, test date, time, force value results, and judgment conclusions, which are affixed to the product or work order for easy traceability. All test data are automatically stored in the industrial control computer's database.
[0032] The working principle of this invention is as follows: First, the air outlet product is placed on the positioning seat 22. After the laser displacement sensor 9 detects that the product is in place, multiple pressing cylinders 24 drive the pressing plate 7 to rotate and move closer to the air outlet product. The air outlet product is fixed on the positioning seat 22 by adjusting the rotation of the pressing plate 7. Then, the PLC controls the Y-axis servo motor 44 to drive the Y-axis lead screw 43 to rotate. Through the threaded engagement, the Y-axis slide 42 and the positioning plate 45 move along the Y-axis direction, so that the part of the air outlet product to be measured moves to the moving path of the pressure sensor 3. Next, the PLC controls the Z-axis servo motor 64 and the X-axis servo motor 55 to drive the Z-axis lead screw 63 and the lower shaft lead screw to rotate respectively. Through the threaded engagement, the pressure sensor 3 is driven to move in the Z-axis and X-axis directions. After the pressure sensor 3 contacts the part of the air outlet product to be measured, it is moved to measure the force. When the force is measured, the Y-axis servo motor 44 drives the Y-axis lead screw 43 to rotate. Through the threaded engagement, the Y-axis slide 42 and the positioning plate 45 move along the Y-axis direction to drive the part of the air outlet product to be measured to move with the pressure sensor 3. During this process, the pressure sensor 3 remains in a fixed position. During the force measurement process, the toggle position detection sensor 23 monitors the position change of the part to be measured in real time. The rotary motor 651 adjusts the toggle angle of the pressure sensor 3 according to the need to change the force direction of the part to be measured of the air outlet product. The pressure sensor 3 transmits the measured force value data to the industrial control computer. After processing the data, the industrial control computer displays the detection result on the display screen 12 and controls the PLC to coordinate the actions of each moving component. After all points have been tested, the pressure cylinder 24 is released, and the operator removes the product. The industrial control computer integrates all the test point data to generate a final report, which is displayed on the display screen 12 and can be printed by the barcode printer 11.
