Description

Technical Field

[0001] The utility model relates to the technical field of sensor production, in particular to a pressure sensor detection device. Background Art

[0002] A pressure sensor is a device or apparatus that can sense a pressure signal and convert the pressure signal into an available output electrical signal according to a certain rule. A pressure sensor usually consists of a pressure-sensitive element and a signal processing unit. According to different types of measured pressures, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors, and absolute pressure sensors.

[0003] Before leaving the factory, it is necessary to detect the internal circuit of the pressure sensor. By detecting the internal circuit of the pressure sensor, the measurement performance and accuracy of the sensor can be verified, which includes checking the stability of the sensor output signal, the response time, and the linear relationship with the expected input pressure value. These detections ensure that the sensor can provide reliable and accurate pressure measurements during actual use. If the pressure sensor does not work as expected, detecting its internal circuit can help determine the possible problems.

[0004] The conventional method for detecting the internal circuit of a pressure sensor is that the assembly line moves the pressure sensor to the lower part of the test plug board in sequence, and the lifting mechanism drives the pins of the test plug board to move downward to connect with the pins of the pressure sensor, and the internal circuit is detected by the detection device connected to the test plug board. This method requires the pressure sensor to accurately stop under the test plug board, not only requires a positioning mechanism for positioning, but also requires a control mechanism to control the start and stop of the assembly line, which affects the fluency of the detection process.

[0007] In one example, two arc-shaped grooves are formed at the top of the arc track. The same arc-shaped rod is fixedly installed between the inner walls on both sides of the arc-shaped groove. Two cylinders are fixedly installed at the bottom of the track slider, and the cylinders are slidably sleeved on the outer sides of the corresponding arc-shaped rods.

[0029] As Figures 1 to 5 shown, an embodiment of the present utility model provides a pressure sensor detection device, including an arc track 1 and a turntable 2.

Specific detection devices include oscilloscopes, multimeters, signal generators, etc. The electrical characteristics of the internal circuit of the pressure sensor unit 3 are detected to obtain electrical parameters such as voltage, current, and resistance of the internal circuit of the pressure sensor unit 3.

[0031] It should also be noted that the left end of the arc track 1 and the right end of the inclined plane track 15 are both connected to the conveyor belt, thereby realizing the interval feeding function of the pressure sensor unit 3 and the feeding and collecting function of the pressure sensor unit 3.

[0032] As Figure 4 and Figure 5 As shown, two arc-shaped grooves are formed at the top of the arc track 1. The same arc-shaped rod 16 is fixedly installed between the inner walls on both sides of the arc-shaped groove. Two cylinders are fixedly installed at the bottom of the track slider 6, and the cylinders are slidably sleeved outside the corresponding arc-shaped rod 16.

[0033] A return spring 17 is fixedly installed on the outside of the cylinder. One end of the return spring 17 is fixedly connected to the inner wall of one side of the corresponding arc-shaped groove. The return spring 17 is wound around the corresponding arc-shaped rod 16, playing a role in guiding the movement and resetting of the track slider 6.

[0034] As Figure 1 and Figure 2 As shown, a connection groove is provided at the center of the top of the pressure sensor unit 3. A pin 12 is provided on the bottom inner wall of the connection groove. The connection groove is adapted to the pin 11. The metal pin 11 provided on the test board 10 is directly docked with the pin on the pressure sensor unit 3, thereby connecting the internal circuits of the test board 10 and the pressure sensor unit 3.

[0035] As Figure 1 and Figure 4 As shown, the bend plate 14 includes a top short plate and a bottom long plate. An inclined plate is connected between the top short plate and the bottom long plate. Through the two sections with different heights of the bend plate 14, the movement of the test board 10 is restricted, driving the test board 10 and the pin 11 to move downward together.

[0036] As Figure 2 and Figure 3 As shown, two vertical grooves are formed on the front side of the fixed plate 9. The same guide plate 18 is fixedly installed between the top inner wall and the bottom inner wall of the vertical groove. The lifting plate 19 is fixedly installed on the outside of the guide plate 18.

[0038] Working principle: The conveyor belt transports the pressure sensor unit 3 to the right end of the arc track 1 at intervals. The output shaft of the drive motor 5 drives the turntable 2 to rotate, thereby driving a plurality of push plates 4 to perform circular motion. The push plate 4 drives the pressure sensor unit 3 to move along the arc track 1 until the pressure sensor unit 3 contacts the magnetic ring plate 7. The magnetic ring plate 7 adsorbs the pressure sensor unit 3 made of metal. Thereafter, the push plate 4 drives the pressure sensor unit 3, the magnetic ring plate 7 and the track slider 6 to move together. The track slider 6 drives the vertical plate 8, the fixing plate 9 and the test plate 10 to move together. The track slider 6 synchronously drives the cylinder to move along the arc-shaped rod 16 and compress the return spring 17, so that the test plate 10 moves along the bottom of the bend plate 14. When the test plate 10 moves from the top short plate of the bend plate 14 to the bottom long plate, the test plate 10 is restricted by the bend plate 14 and moves downward, thereby driving the pin 11 to move downward and insert into the connection groove, so that the pin 11 is connected to the pin 12, and the detection device is connected to the internal circuit of the pressure sensor unit 3 through the test plate 10, thereby performing an electrical test. When the pressure sensor unit 3 moves to the inclined plane track 15, the pressure sensor unit 3 slides downward along the inclined plane track 15 and disengages from the magnetic ring plate 7. Under the action of the return spring 17, the track slider 6, the vertical plate 8, the fixing plate 9, the test plate 10 and the magnetic ring plate 7 are reset to the initial position. Repeat the above process to perform electrical detection on multiple pressure sensor units 3 in sequence.
