Description

Technical Field

[0001] This utility model relates to the field of testing platform technology, specifically to a pressure sensor testing platform. Background Technology

[0002] A pressure sensor is a device that senses pressure signals and converts them into a usable output electrical signal. During the manufacturing process of pressure sensors, sampling inspection is required.

[0003] Chinese patent document CN 216746568U discloses a pressure sensor testing platform. It uses an air pump to continuously deliver gas to the interior of a fixed cylinder via a first connecting pipe. As the air pressure inside the fixed cylinder increases, a piston drives a piston rod to move downwards along the inner side of the fixed cylinder. However, this technical solution has the following drawbacks: In existing technologies, the pressure sensor is directly placed on a mounting plate structure and tested by pressing down with a testing rod. This makes it difficult to ensure accurate placement of the pressure sensor, affecting subsequent testing. Furthermore, manually adjusting the pressure sensor poses a safety risk due to its proximity to the testing rod.

[0004] Therefore, a pressure sensor testing station is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a pressure sensor detection station in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A pressure sensor detection platform includes a base, a support plate is disposed on the top of the base, a transfer component for controlling the longitudinal movement of the support plate is installed on the top surface of the base, an alignment component is disposed on the rear side of the top surface of the base, a fixing frame is fixedly connected to the top surface of the base, and a pressure detection component and a pressure adjustment component are disposed on the top surface of the fixing frame.

[0008] Furthermore, the transfer assembly includes two mounting boxes, both of which are fixedly connected to the base. A first motor is fixedly installed on the inner wall of the left mounting box, and a threaded column is fixedly connected to the output end of the first motor. A sliding column is fixedly connected to the inner wall of the right mounting box. Connecting blocks are fixedly connected to both sides of the bearing plate. The connecting block on the left is threadedly connected to the threaded column, and the connecting block on the right is slidably connected to the sliding column.

[0009] Furthermore, the alignment component includes a fixing box, which is fixedly connected to the top surface of the base. A second motor is fixedly installed on the inner wall of the fixing box. A double-ended screw is fixedly connected to the output end of the second motor. A connecting rod is threadedly connected to the surface of the double-ended screw, and the connecting rod is slidably connected to the inner wall of the fixing box. An arc-shaped locking block is fixedly connected to the end of the connecting rod.

[0010] Furthermore, the pressure detection component includes a storage tube, which is movably inserted into a fixing frame. A pressure plate is fixedly connected to the bottom surface of the storage tube, and a baffle is fixedly connected to the surface of the storage tube. An electric push rod is fixedly installed on the top surface of the fixing frame, and the top of the telescopic end of the electric push rod is in contact with the bottom of the baffle.

[0011] Furthermore, the pressure adjustment assembly includes a storage tank, which is fixedly connected to the top surface of the mounting bracket. Two water pumps are fixedly installed on the top of the storage tank, and a connecting pipe is movably inserted into the top of the storage pipe. The outlet end of one of the water pumps is fixedly connected to the connecting pipe, and the inlet end of the other water pump is fixedly connected to the connecting pipe.

[0012] Furthermore, the surface of the storage tube is provided with scale lines.

[0013] The beneficial effects of this utility model are as follows:

[0014] The tester places the pressure sensor on the top surface of the support plate and moves the support plate backward using the transfer component, so that the pressure sensor is roughly below the pressure detection component. The pressure sensor is then aligned and fixed using the alignment component. Subsequently, the pressure sensor can be squeezed and detected by the pressure detection component. The weight of the pressure detection component can be adjusted by the pressure adjustment component, thereby changing the pressure on the pressure sensor. In use, this achieves the effect of automatic detection of the pressure sensor, and can automatically align the position of the pressure sensor, thus ensuring the accuracy of subsequent tests and reducing safety risks during operation.

[0025] like Figures 1 to 4As shown, a pressure sensor testing platform includes a base 1, a support plate 2 on top of the base 1, a transfer assembly 3 for controlling the longitudinal movement of the support plate 2 mounted on the top surface of the base 1, a leveling assembly 4 on the rear side of the top surface of the base 1, and a fixing frame 7 fixedly connected to the top surface of the base 1. A pressure detection assembly 5 and a pressure adjustment assembly 6 are mounted on the top surface of the fixing frame 7. More specifically, the tester places the pressure sensor on the top surface of the support plate 2, controls the support plate 2 to move rearward using the transfer assembly 3, so that the pressure sensor is approximately below the pressure detection assembly 5. The leveling assembly 4 levels and fixes the pressure sensor, and then the pressure detection assembly 5 can perform compression detection on the pressure sensor. The pressure adjustment assembly 6 can adjust the weight of the pressure detection assembly 5, thereby changing the pressure on the pressure sensor.

[0026] The transfer assembly 3 includes two mounting boxes 301, both of which are fixedly connected to the base 1. A first motor 302 is fixedly mounted on the inner wall of the left mounting box 301, and a threaded post 303 is fixedly connected to the output end of the first motor 302. A sliding post 304 is fixedly connected to the inner wall of the right mounting box 301. Connecting blocks 305 are fixedly connected to both sides of the support plate 2. The left connecting block 305 is threadedly connected to the threaded post 303, and the right connecting block 305 is slidably connected to the sliding post 304. It should be noted that when the first motor 302 operates, it drives the threaded post 303 to rotate, thereby causing the connecting block 305 to move, which controls the movement of the support plate 2. The right connecting block 305 will slide along the surface of the sliding post 304, making the movement of the support plate 2 more stable.

[0027] The alignment component 4 includes a fixing box 401, which is fixedly connected to the top surface of the base 1. A second motor 402 is fixedly installed on the inner wall of the fixing box 401. A double-ended screw 403 is fixedly connected to the output end of the second motor 402. A connecting rod 404 is threadedly connected to the surface of the double-ended screw 403, and the connecting rod 404 is slidably connected to the inner wall of the fixing box 401. An arc-shaped locking block 405 is fixedly connected to the end of the connecting rod 404. More specifically, the second motor 402 drives the double-ended screw 403 to rotate, thereby causing the connecting rod 404 to slide along the inner wall of the fixing box 401, so that the arc-shaped locking block 405 approaches the pressure sensor. The pressure sensor is centered and aligned using the arc-shaped locking blocks 405 on both sides.

[0028] The pressure detection component 5 includes a storage tube 501, which is movably connected to the mounting bracket 7. A pressure plate 502 is fixedly connected to the bottom surface of the storage tube 501, and a baffle 504 is fixedly connected to the surface of the storage tube 501. An electric push rod 503 is fixedly installed on the top surface of the mounting bracket 7, and the top of the telescopic end of the electric push rod 503 is in contact with the bottom of the baffle 504. It should be noted that when the pressure sensor is directly below the pressure plate 502, the telescopic end of the electric push rod 503 shortens, causing the baffle 504, storage tube 501, and pressure plate 502 to descend. Finally, the pressure plate 502 rests on top of the pressure sensor. The telescopic end of the electric push rod 503 continues to shorten, so that the telescopic end no longer contacts the baffle 504. The pressure adjustment component 6 can increase or decrease the water volume inside the storage tube 501, causing a change in the overall weight of the storage tube 501. By comparing the water volume with the pressure sensor reading, the accuracy of the pressure sensor can be detected.

[0029] The pressure regulating assembly 6 includes a storage tank 601, which is fixedly connected to the top surface of the mounting bracket 7. Two water pumps 602 are fixedly installed on the top of the storage tank 601. A connecting pipe 603 is movably inserted into the top of the storage pipe 501. The outlet end of one water pump 602 is fixedly connected to the connecting pipe 603, and the inlet end of the other water pump 602 is fixedly connected to the connecting pipe 603. More specifically, when one water pump 602 operates, it can send water from inside the storage tank 601 into the connecting pipe 603, thereby increasing the water volume inside the storage pipe 501. When the other water pump 602 operates, it can extract water from inside the storage pipe 501, thereby decreasing the water volume inside the storage pipe 501.

[0030] The surface of the storage tube 501 is provided with scale lines 505. It should be noted that by setting scale lines 505, the specific water volume inside the storage tube 501 can be easily observed.

[0031] In summary: The tester places the pressure sensor on the top surface of the support plate 2, and controls the support plate 2 to move backward using the transfer component 3, so that the pressure sensor is approximately below the pressure detection component 5. The pressure sensor is then aligned and fixed using the alignment component 4. Subsequently, the pressure sensor can be squeezed and detected by the pressure detection component 5. The weight of the pressure detection component 5 can be adjusted by the pressure adjustment component 6, thereby changing the pressure on the pressure sensor. In use, this achieves the effect of facilitating automatic detection of the pressure sensor, automatically aligning the position of the pressure sensor, thus ensuring the accuracy of subsequent tests and reducing safety risks during operation.
