[0002] In the bidirectional gas circulation of an air suspension system, it is necessary to sense the gas pressure in the air tank and air spring. Before the pressure sensor is installed on the valve body, its port quality needs to be tested to ensure stable installation. Existing pressure sensor testing mechanisms mainly include a loading machine, a unloading machine, and a testing platform. The loading machine sends the pressure sensor to be tested to the testing platform, and the testing end of the testing equipment takes pictures of the pressure sensor. However, this testing method is a static testing method, which cannot comprehensively test the quality of the pressure sensor port and may reduce the testing quality of the pressure sensor port.

[0012] 1. In this utility model, the pressure sensor to be tested is placed in the test piece placement rack.

The suction component picks up the material, and then moves the pressure sensor in the test piece placement rack to the rotating component.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0022] Example: A quality inspection mechanism for a pressure sensor, including a working fixed plate 1, as shown in the attached figure. Figure 1As shown, a main support frame 2, a light source 12, a first sensor 13, and a second sensor 17 are mounted on the working fixed plate 1. A horizontal moving assembly 3 is mounted on the main support frame 2. A vertical cylinder 4 is mounted on the moving end of the horizontal moving assembly 3. A feeding cylinder 5 is mounted on the extended end of the vertical cylinder 4. The horizontal moving assembly, the vertical cylinder, and the feeding cylinder work together. A rotary cylinder 6 is connected to the extended end of the feeding cylinder 5. A semi-circular rotating seat 7 is mounted on the rotating end of the rotary cylinder 6. A suction assembly 8 for absorbing the pressure sensor is mounted at the end of the semi-circular rotating seat 7. A detection platform 9 is mounted on the working fixed plate 1. A swivel assembly 10 for rotating the pressure sensor is installed inside the detection platform 9. A test piece placement rack 11 is mounted on the side of the detection platform 9. The test piece placement rack has two workstations. A position sensor is provided at the bottom of the test piece placement rack to detect whether a pressure sensor is placed there. The light source 12, the first sensor 13, and the second sensor 17 are mounted on the working fixed plate 1. Sensor 17 is arranged around the detection platform 9. The light source is mainly used to enhance the brightness of the detection environment. The first sensor mainly detects the flatness of one end of the pressure sensor and whether there are any gaps or damages. The other end of the pressure sensor is mainly a metal head that connects to other electrical components. The second sensor is used to check whether the metal head is damaged or bent. In this embodiment, the first and second sensors are photoelectric sensors, using the Sick W2S series. This is a high-performance photoelectric sensor with extremely high accuracy and sensitivity, suitable for object detection in automated equipment. The housing of this type of sensor is also relatively robust, and the sensor is not affected by chemical, thermal, and mechanical environments. The light source 12 includes a rod 121 fixed on the working plate 1. The upper end of the rod 121 is provided with a lamp body fixing seat 122. The lamp body fixing seat 122 has two spliced ​​clamping plates 123. An illumination element 124 is installed between the two clamping plates 123. The structure is simple and easy to install. Since the second sensor is located on the side of the testing platform, after the pressure sensor completes the inspection of one end face, the semi-circular rotating seat drives the pressure sensor to rotate, and the other end face of the pressure sensor corresponds with the second sensor to achieve end face detection.

[0023] The lateral movement assembly 3 includes a lateral plate 31 mounted on the main support frame 2 and a lateral rodless cylinder 32. The moving end of the lateral rodless cylinder 32 is equipped with a main plate 33 that is slidably connected to the lateral plate 31. The vertical cylinder 4 is mounted on the main plate 33. The lateral rodless cylinder serves as a power source, driving the main plate to move. The lateral movement assembly also functions as a material discharge assembly, delivering the completed pressure sensor to the next workstation.

[0024] The extended end of the vertical cylinder 4 is equipped with a right-angle plate 14, as shown in the attached figure. Figure 2As shown, a slide rail 15 is mounted on the vertical cylinder 4, and a right-angle plate 14 fits into the slide rail 15. A connecting plate 16 is mounted on the lower end of the right-angle plate 14, and the discharge cylinder 5 is located below the connecting plate 16. A stable connection between the vertical cylinder and the discharge cylinder is achieved through a multi-plate connection structure. The suction assembly 8 includes a fixing plate 81 mounted on the semi-circular rotating seat 7, as shown in the attached diagram. Figure 3 and 4 As shown, a positioning seat 82 is installed at the inner end of the semi-circular rotating seat 7, and a straight tube 83 is installed inside the positioning seat 82. The upper end of the straight tube 83 is connected to an air supply hose 84. One end of the air supply hose 84 passes through the rotating cylinder 6 and is connected to a negative pressure source. A stabilizing block 85 is installed at the lower end of the straight tube 83. A negative pressure is generated in the air supply hose and the straight tube. When the pressure sensor is inserted into the port of the straight tube, the negative pressure generated in the tube can attract the pressure sensor. This type of robotic gripping can effectively avoid deformation caused by gripping and play a better role in protecting the pressure sensor.

[0025] The swirl assembly 10 includes an active motor 101 mounted on the detection table 9, as shown in the attached figure. Figure 5 As shown, the extended end of the drive motor 101 is connected to a drive pulley 102. A fixed frustum 103 is mounted on the detection platform 9, and a rotatable material platform 104 is mounted on the fixed frustum 103. A driven pulley 105 is mounted on the outer side of the material platform 104. A belt 106 is wound around the drive pulley 102 and the driven pulley 105. Since dynamic detection of the pressure sensor port is required, the rotation of the material platform is achieved through belt drive. The pressure sensor is mounted inside the material platform. A protective cover 91 is provided on the detection platform 9, and the protective cover 91 has a through groove 92. The placement opening of the material platform 104 is in the through groove 92. The protective cover can effectively protect the belt drive assembly and reduce the impact of dust on the belt drive.

[0026] The working principle of this invention is as follows: The pressure sensor to be tested is placed in the test piece placement rack. The horizontal moving component, the feeding cylinder, and the vertical cylinder work together. The suction component picks up the material and then moves the pressure sensor in the test piece placement rack to the rotating component. The rotating component drives the pressure sensor to rotate, and the light source shines on the testing platform. The first sensor detects the pressure sensor port. Then, the suction component removes the pressure sensor, and the rotating cylinder operates so that the other end of the pressure sensor faces the second sensor, allowing for detection of the other end of the pressure sensor. The rotating component in this invention drives the pressure sensor to rotate, enabling dynamic detection of the pressure sensor and improving the detection effect and quality of the pressure sensor port.
