A sensor is a device that identifies electrical, physical, or other quantitative progress, helping to detect, analyze, measure, and process various changes, such as changes in position, length, height, external dimensions, and misalignment occurring in industrial production sites, to confirm production progress and deliver benefits. Sensors also play a vital role in predicting and preventing numerous potential processes, thus meeting the needs of many industrial sensing applications. Commonly used sensors in automation include: pressure sensors, temperature sensors, MEMS sensors, torque sensors, magnetic switches, proximity switches, photoelectric sensors, displacement sensors, and optical gratings. With the large-scale shift of industrial production towards automation, and the continuous commercialization of IoT and cloud platform applications, the development of automation in the industrial sector is trending towards a higher level: intelligent manufacturing.

Existing methods, such as using multiple sensors to sense parts of different sizes or adjusting the sensor positions when producing different parts, result in higher production costs.

[0004] Therefore, it is necessary to design a pressure sensor device to solve the above problems. Utility Model Content

[0022] (Example 1)

[0023] See Figure 1 and Figure 2 This embodiment of a pressure sensor device includes a housing 1 and a sensor 2, a sensing block assembly 3, and a contact assembly 4 sequentially disposed within the housing 1. The sensor 2 is a proximity sensor. One end of the contact assembly 4 extends out of the housing 1 to receive external pressure signals. The sensing block assembly 3 is repositionably disposed between the sensor 2 and the contact assembly 4 to transmit pressure signals to the sensor 2.

[0024] Furthermore, the housing 1 has an open end, and its open end is provided with an end cap 5 for closing the housing 1 and protecting the internal components. The housing 1 has multi-stage stepped holes inside, providing sliding tracks and limiting structures for the sensing block assembly 3 and the contact assembly 4.

[0025] Furthermore, the sensing block assembly 3 includes a sensing block 31 and a copper sleeve 32 fitted onto the sensing block 31. The copper sleeve 32 is slidably connected to the middle of the multi-step hole to ensure that the sensing block 31 can move smoothly. A first spring 33 is provided between one end of the sensing block 31 and the sensor 2 to provide a reset force; a second spring 34 is provided between the other end of the sensing block 31 and the contact assembly 4, also to provide a reset force and increase the buffering effect.

[0026] Furthermore, the contact assembly 4 includes a contact rod 41, the outer end of which extends out of the outer casing 1 through the end cover 5 to receive external contact pressure. The inner end of the contact rod 41 is limited by a step to the end cover 5, ensuring that the contact rod 41 will not detach from the outer casing 1 during movement. The step at the inner end of the contact rod 41 is slidably connected to the middle of a multi-stage stepped hole, enabling smooth movement of the contact rod 41. A receiving groove 42 for a second spring 34 is provided in the middle of the step at the inner end of the contact rod 41 for mounting the second spring 34. One end of the second spring 34 abuts against the sensing block 31, and the other end abuts against the receiving groove 42, realizing buffering and reset between the contact assembly 4 and the sensing block assembly 3.

[0027] Furthermore, a sealing ring 43 is provided between the contact rod 41 and the end cover 5 to improve the sealing performance of the sensor 2 and prevent external dust, moisture and other impurities from entering the sensor 2 and affecting its normal operation.

[0028] Furthermore, one end of the first spring 33 abuts against the copper sleeve 32, and the other end abuts against the stepped surface in the middle of the multi-step hole, providing a stable reset force for the sensing block 31. The sensor 2 is fixed in the small end of the multi-step hole, ensuring that the sensor 2 can accurately receive the touch pressure signal transmitted by the sensing block 31. The housing 1 is provided with a viewing hole 6 corresponding to the sensor light of the sensor 2, for observing the working status of the sensor 2.

[0029] The working principle of this embodiment: In the free state of the touch sensor, the copper sleeve 32 is pushed by the spring force of the first spring 33. The copper sleeve pushes the stepped surface of the touch rod 41 to always be close to the end face of the end cover 5. Under the spring force of the second spring 34, the stepped surface of the sensing block is kept close to the bottom surface of the inner hole of the copper sleeve 32. The small shaft end face of the sensing block 31 is close to the sensing range of the sensor 2. When the touch rod 41 is pushed, the touch rod 41 pushes the copper sleeve 32 to move into the sensor together. The sensing block 31 moves into the sensing range of the sensor 2 under the action of the second spring 34, and the sensor senses and sends a signal.

[0030] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
