Technical Field

[0001] This application relates to the field of pressure sensor processing and manufacturing, and in particular to a pressure sensor pressing device. Background Technology

[0002] A pressure sensor is an electronic component or device that converts physical pressure signals, such as the pressure of gases or liquids or the contact pressure of solid surfaces, into measurable and transmittable electrical signals, such as voltage or current. In the manufacturing process of pressure sensors, the pressing process is a key step to ensure their performance and quality.

[0003] Current pressure sensor pressing devices are not precise enough in positioning the pressure sensor, and are prone to displacement during the pressing process, resulting in inaccurate pressing position, affecting product consistency and reliability. The pressure applied during pressing is difficult to control; excessive pressure may damage the internal components of the sensor, while insufficient pressure may lead to weak adhesion and affect the normal operation of the sensor. Therefore, we propose a pressure sensor pressing device to solve the above problems. Utility Model Content

[0015] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0016] Example 1: Please see Figure 1-4 In this invention, the pressure sensor pressing device includes a base 1. Two first slide rails 20 are formed on the upper surface of the base 1. Two first sliders 21 are slidably connected inside each of the two first slide rails 20. A baffle 22 is fixedly connected to the upper surface of each set of first sliders 21. Two first cylinders 8 are fixedly connected to the upper surface of the base 1. The output ends of the two first cylinders 8 are fixedly connected to the outer surface of the baffles 22. Push rods 23 are fixedly connected to the sides of the two baffles 22 that are close to each other. Clamping plates 24 are fixedly connected to the sides of the two push rods 23 that are close to each other. A first pressure sensor 26 and a support plate 25 are installed on the sides of the two clamping plates 24 that are close to each other. The controller 4 activates the two first cylinders 8, and the output ends of the first cylinders 8 push the baffles 22. The baffle 22 moves, causing the first slider 21 to slide within the first slide rail 20. At the same time, the push rod 23 moves with the baffle 22, causing the two clamping plates 24 to move closer to each other until the bearing plate 25 on the clamping plate 24 contacts the pressure sensor. At this time, the first pressure sensor 26 on the clamping plate 24 can sense the contact pressure, ensuring that the clamping force on the pressure sensor is appropriate and achieving positioning. The upper surface of the base 1 is fixedly connected to the bearing column 19, and the upper surface of the bearing column 19 is fixedly connected to the suction plate 18. The upper surface of the suction plate 18 has multiple suction holes 17. The pressure sensor is placed on the upper surface of the suction plate 18. The vacuum pump 5 is started. The vacuum pump 5 is connected to the inside of the suction plate 18 through the bearing column 19, so that the multiple suction holes 17 on the suction plate 18 generate suction force, forming a preliminary adsorption and fixation of the pressure sensor.

[0017] Example 2: A fixed frame 6 is fixedly connected to the bottom surface of the base 1. A vacuum pump 5 is fixedly connected inside the fixed frame 6. The output end of the vacuum pump 5 passes through the bearing column 19 and is fixedly connected to the suction plate 18. A support frame 12 is fixedly connected to the upper surface of the base 1. A second cylinder 13 is fixedly connected to the outer surface of the support frame 12. A fixed block 14 is fixedly connected to the output end of the second cylinder 13. Two fixed rods 7 are fixedly connected to the upper surface of the base 1. A second slide rail 11 is opened on the side of the two fixed rods 7 that are close to each other. A second slider 10 is slidably connected inside the two second slide rails 11. A moving rod 9 is fixedly connected to the side of the two second sliders 10 that are close to each other. One end of the two moving rods 9 is fixedly connected to the outer surface of the fixed block 14. A second pressure sensor 15 is installed on the bottom surface of the fixed block 14. A pressure block 16 is fixedly connected to the bottom surface of the second pressure sensor 15.

[0018] The controller 4 controls the second cylinder 13 to start. The output end of the second cylinder 13 pushes the fixed block 14 to move downward. The fixed block 14 drives the moving rod 9 to move. The second sliders 10 at both ends of the moving rod 9 slide in the second slide rail 11 of the fixed rod 7, providing guidance for the movement of the pressure block 16, so that the pressure block 16 moves smoothly towards the pressure sensor and performs the pressing operation. The second pressure sensor 15 on the bottom surface of the fixed block 14 monitors the pressure applied by the pressure block 16 in real time and transmits the pressure information to the controller 4. The controller 4 adjusts the second cylinder 13 according to the preset parameters to ensure that the pressing pressure meets the requirements. The controller 4 is installed on the outer surface of the base 1. Multiple support legs 2 are fixedly connected to the bottom surface of the base 1. Each support leg 2 has an anti-slip pad 3 installed on its bottom surface. The base 1 is kept stable by the support legs 2 and the anti-slip pad 3. All components operate in an orderly manner under the overall coordination of the controller 4 to realize the positioning and pressing of the pressure sensor.

[0019] The working principle of this application is: First, place the pressure sensor on the upper surface of the suction plate 18, start the vacuum pump 5, and activate the two first cylinders 8 via the controller 4. The output end of the first cylinder 8 pushes the baffle 22 to move, and the baffle 22 drives the first slider 21 to slide within the first slide rail 20. At the same time, the push rod 23 moves with the baffle 22, causing the two clamping plates 24 to move closer to each other until the bearing plate 25 on the clamping plate 24 contacts the pressure sensor. At this time, the first pressure sensor 26 on the clamping plate 24 can sense the contact pressure, ensuring that the clamping force on the pressure sensor is moderate and achieving accurate positioning. After positioning is completed, the controller 4 controls the second cylinder 13 to start, and the output end of the second cylinder 13 pushes the fixing block 14 downward. 14 drives the moving rod 9 to move, and the second sliders 10 at both ends of the moving rod 9 slide in the second slide rail 11 of the fixed rod 7, providing guidance for the movement of the pressure block 16, so that the pressure block 16 smoothly approaches the pressure sensor and performs the pressing operation. During the pressing process, the second pressure sensor 15 on the bottom surface of the fixed block 14 monitors the pressure applied by the pressure block 16 in real time and transmits the pressure information to the controller 4. The controller 4 adjusts the second cylinder 13 according to the preset parameters to ensure that the pressing pressure meets the requirements. After the pressing is completed, the second cylinder 13 drives the pressure block 16 to reset, the first cylinder 8 drives the clamping plate 24 to reset, the vacuum pump 5 stops working, the suction of the suction hole 17 disappears, and the pressed pressure sensor can be taken out.
