Description

Technical Field

[0001] The present application relates to the technical field of sensor quality detection, and in particular to a sensor length detection mechanism. Background Art

[0002] A sensor is a detection device that can sense the information being measured and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control.

[0003] During the production process of sensors, the length of the produced sensor probes may deviate from the standard size due to insufficient equipment accuracy, operating errors or improper material handling. Whether the length of the sensor probe meets the standard is particularly critical, which will affect the subsequent installation and use of the sensor. Therefore, customers widely require 100% inspection to achieve the goal of zero defects on the line. However, the conventional inspection method is to use a standard caliper to measure the length of the sensor probes one by one, which is inefficient and difficult to meet production needs. Utility Model Content

[0004] In order to solve the above problems, the present application provides a sensor length detection mechanism.

[0005] The sensor length detection mechanism provided in this application adopts the following technical solution:

[0006] A sensor length detection mechanism, comprising a detection mechanism and a sensor movably arranged in the detection mechanism, the sensor comprising a sensor body, a tube shell fixedly arranged outside the sensor body, and a probe fixedly arranged at one end of the sensor body, the detection mechanism comprising a detection platform, a detection hole opened in the detection platform, and a detection component arranged in the detection hole, the tube shell movably arranged in the top of the matching detection hole, the probe is accommodated in the detection hole, a positioning plate is arranged in the detection hole of the detection platform, an elastic member is fixedly arranged on the top of the positioning plate, and a pressure plate located at the bottom of the probe is fixedly arranged on the top of the elastic member;

[0007] The detection component includes a touch switch fixed on the top of the positioning plate, and a pressure block fixed on the bottom of the pressure plate and located directly above the touch switch. An indication component for indicating after the touch switch is powered on is provided on the outside of the detection platform.

[0008] By adopting the above technical solution, the sensor is inserted into the detection hole, and the sensor shell is completely inserted into the corresponding detection hole. If the sensor probe is shorter, the touch switch cannot contact the pressure block, and the indicating mechanism has no response, so it is judged that the probe is shorter and does not meet the standard. If the sensor probe is compliant or longer, the pressure block will contact the touch switch, and the indicating mechanism will be energized for prompting. At this time, if the sensor shell exceeds the top surface of the detection table, the sensor probe is too long and does not meet the standard. If it does not exceed, the sensor probe length meets the standard.

[0009] Preferably, the indicating assembly includes an indicator light and a sound alarm fixedly arranged on the outside of the testing platform.

[0010] By adopting the above technical solution, the user is indicated by two ways, namely, the sound of the sound alarm and the lighting of the indicator light, and the indication effect is better.

[0011] Preferably, the positioning plate is slidably connected in the detection hole of the detection platform, the elastic member includes two groups of springs fixedly arranged on both sides of the top of the positioning plate, and the pressure plate is fixedly connected to the top ends of the two groups of springs.

[0012] By adopting the above technical solution, the spring can elastically connect the positioning plate and the pressing plate, and elastically support the pressing plate.

[0013] Preferably, a partition is fixedly provided at the bottom of the detection hole of the detection platform, an adjusting bolt is threadedly connected to the inner thread of the partition, a rotating block rotatably connected to the positioning plate is fixedly provided at the top of the adjusting bolt, a limiting rod is fixedly provided at the bottom of the positioning plate, the bottom end of the limiting rod passes through and extends to the bottom of the partition, and an enlarged hole for a tool to rotate the adjusting bolt is opened at the bottom of the detection hole of the detection platform.

[0014] By adopting the above technical solution, the positioning plate can be driven to rise and fall by rotating the adjusting bolt, so that the distance between the pressure plate and the sensor probe can be adjusted, which makes it easier for the detection mechanism to detect sensors with probes of different length scale specifications.

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] 1. By inserting the sensor into the detection hole and making the sensor shell completely enter the matching detection hole, if the sensor probe is shorter, the touch switch cannot contact the pressure block, and the indicating mechanism has no response, so it is judged that the probe is short and does not meet the standard. If the sensor probe is compliant or longer, the pressure block will contact the touch switch, and the indicating mechanism will be powered on to emit sound and light information for prompting. At this time, if the sensor shell exceeds the top surface of the detection table, the sensor probe is too long and does not meet the standard. If it does not exceed, the sensor probe length meets the standard. On the whole, the user only needs to plug and unplug the sensor in the detection table to complete the detection, which is convenient and quick, and improves the detection efficiency of the sensor.

[0017] 2. By rotating the adjusting bolt, the positioning plate can be driven to rise and fall, thereby adjusting the distance between the pressure plate and the sensor probe, which is convenient for the detection mechanism to detect sensors with probes of different lengths and specifications. It has a wide range of applications and can indicate to the user through the sound of the sound alarm and the lighting of the indicator light. The indication effect is better and it is convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-Figure 4 This application is described in further detail.

[0024] The embodiment of the present application discloses a sensor length detection mechanism.

[0025] A sensor length detection mechanism, referring to Figure 1-3 , including detection mechanisms and sensors.

[0026] The detection mechanism includes a detection platform 1 , a detection hole 11 provided in the detection platform 1 , and a detection component provided in the detection hole 11 . The detection hole 11 is provided throughout the detection platform 1 .

[0027] The sensor includes a sensor body 2, a tube shell 21 fixed on the outside of the sensor body 2, and a probe 22 fixed on one end of the sensor body 2. The sensor body 2 is the main body of the sensor 2. The sensor body 2, the tube shell 21 and the probe 22 constitute the existing sensor, and its internal structure, shape and principle have been disclosed and will not be elaborated here.

[0028] Reference Figure 1 and Figure 3 The tube shell 21 is movably arranged in the top of the corresponding detection hole 11, and the probe 22 is accommodated in the detection hole 11. The detection platform 1 can support and limit the corresponding tube shell 21 through the top of the detection hole 11, so that the top surface of the tube shell 21 is flush with the top surface of the detection platform 1, and the probe 22 is located inside the detection hole 11.

[0029] Reference Figure 3-4 A positioning plate 3 is provided in the detection hole 11 of the detection platform 1, an elastic member is fixedly provided on the top of the positioning plate 3, a pressing plate 32 located at the bottom of the probe 22 is fixedly provided on the top of the elastic member, the positioning plate 3 is slidably connected in the detection hole 11 of the detection platform 1, the elastic member includes two groups of springs 31 fixedly provided on both sides of the top of the positioning plate 3, the pressing plate 32 is fixedly connected to the top ends of the two groups of springs 31, the detection platform 1 can limit the positioning plate 3 through the detection hole 11, the spring 31 can elastically connect the positioning plate 3 and the pressing plate 32, and elastically support the pressing plate 32.

[0030] Reference Figure 3-4 The detection component includes a touch switch 33 fixed on the top of the positioning plate 3, and a pressing block 34 fixed on the bottom of the pressing plate 32 and located directly above the touch switch 33. An indicating component for indicating after the touch switch 33 is powered on is provided on the outside of the detection platform 1. When the probe 22 of the sensor is short, the pressing plate 32 pressed down by the probe 22 cannot contact the touch switch 33, and the indicating mechanism cannot be powered on. At this time, the indicating mechanism has no response, which means that the length of the probe 22 is short and does not meet the standard. If the length of the sensor probe 22 is compliant or longer, the pressing block 34 pressed down by the probe 22 will contact the touch switch 33 to turn on the touch switch 33, so that the indicating mechanism is powered on to prompt the user. At this time, if the sensor shell 21 exceeds the top surface of the detection platform 1, the sensor probe 22 is too long and does not meet the standard. If it does not exceed, the length of the sensor probe 22 meets the standard.

[0031] Reference Figure 1-3 The indication component includes an indicator light 35 and a sound alarm 36 fixedly arranged on the outside of the detection platform 1. The indicator light 35 can be a lamp such as an LED lamp that can emit light to remind the user, and the sound alarm 36 can be an instrument such as a buzzer that can emit sound to remind the user. The user is indicated by the sound of the sound alarm 36 and the lighting of the indicator light 35, and the indication and reminder effects are better. The circuit connection between the indicator light 35, the sound alarm 36 and the touch switch 33 is an existing common technology, usually connected in series with a wire. The above circuit connection has been disclosed and will not be repeated here.

[0032] Reference Figure 3A partition plate 4 is fixedly provided at the bottom of the detection hole 11 of the detection platform 1, and an adjusting bolt 41 is connected to the inner thread of the partition plate 4. When the user rotates the adjusting bolt 41, the adjusting bolt 41 will be driven to rise and fall in the detection hole 11.

[0033] Reference Figure 3 A rotating block 42 rotatably connected to the positioning plate 3 is fixed at the top of the adjusting bolt 41, and a limiting rod 43 is fixed at the bottom of the positioning plate 3. The bottom end of the limiting rod 43 penetrates and extends to the bottom of the partition 4. The rotating block 42 can connect the adjusting bolt 41 and the positioning plate 3, and the limiting rod 43 can limit the positioning plate 3 so that the positioning plate 3 can only be raised and lowered but cannot be rotated, thereby ensuring the circuit connection of the touch switch 33.

[0034] When the adjusting bolt 41 is rotated, it will drive the positioning plate 3 to move up and down, so as to adjust the distance between the pressing plate 32 and the sensor probe 22, so as to facilitate the detection mechanism to detect sensors of probes 22 of different length scale specifications.

[0035] Reference Figure 3 The bottom of the detection hole 11 of the detection table 1 is provided with an enlarged hole for a tool to rotate the adjusting bolt 41 . The setting of the enlarged hole facilitates the user to extend the sleeve of the electric wrench into the detection hole 11 to rotate the adjusting bolt 41 .

[0036] The implementation principle of a sensor length detection mechanism of the embodiment of the present application is as follows: when in use, the user can insert the sensor to be detected into the detection hole 11, so that the probe 22 of the sensor enters the interior of the detection hole 11, and the tube shell 21 of the sensor completely enters the matching detection hole 11;

[0037] If the probe 22 of the sensor is too short, the pressing plate 32 pressed down by the probe 22 cannot contact the touch switch 33, and the indicating mechanism cannot be powered on. In this case, the lack of response of the indicating mechanism indicates that the probe 22 is too short and does not meet the standard.

[0038] If the sensor probe 22 is of the required length or is relatively long, the pressing block 34 pressed down by the probe 22 will contact the touch switch 33 to turn on the touch switch 33, so that the indicating mechanism is powered on to send out sound and light information to the user through the sound alarm 36 and the indicator light 35. At the same time, if the sensor probe 22 is relatively long, the tube shell 21 will exceed the top surface of the test bench 1 due to the top pressure of the relatively long probe 22. At this time, the user can observe with the naked eye that if the tube shell 21 exceeds the top surface of the test bench 1, it means that the sensor probe 22 is too long and does not meet the standard. If it does not exceed, it means that the length of the sensor probe 22 meets the standard.

[0039] Then the detected sensor is pulled out from the detection platform 1, and the length detection of the next sensor probe 22 can be continued. During the detection, it is only necessary to plug and unplug the sensor, which is convenient and fast, and improves the detection efficiency.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
