After the sensors are soaked for a specified time, they are taken out and their resistance values ​​are measured. The resistance value is used to determine whether the sensors are qualified products.

The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0060] Example

[0061] like Figures 1 to 13 As shown, it includes a detection table 45, on which a coding mechanism 50, a first transplanting mechanism, at least two water bath heating mechanisms 47, a second transplanting mechanism 48 and an air drying mechanism 49 are provided; the coding mechanism 50 is used to code the sensor 9; the first transplanting mechanism is used to transfer the coded sensor 9 to the water bath heating mechanism 47; the water bath heating mechanism 47 is used to heat the sensor 9 to a preset temperature; the second transplanting mechanism 48 and the air drying mechanism 49 are located between two adjacent water bath heating mechanisms 47, and the second transplanting mechanism 48 is used to detect the resistance value of the sensor 9 in the water bath heating mechanism 47 and transfer the sensor 9 to the air drying mechanism 49; the air drying mechanism 49 is used to remove water stains on the sensor 9.

[0062] A stacking unit 2002 for stacking the sensor 9 is also provided on the top of the detection platform 45 . The stacking unit 2002 includes a third slide rail 2003 , a third slide seat, an eighth driving mechanism and a second tooling 2039 for placing the sensor 9 .

[0063] The bottom of the third slide rail 2003 is fixed on the detection table 45, the third slide seat is slidably connected to the third slide rail 2003, the output end of the eighth driving mechanism is connected to the third slide seat, and the second tooling 2039 is fixed on the third slide seat.

[0064] The detection platform 45 is also provided with a plurality of support columns, on which a pressure module is provided, and the second tooling 2039 is placed on the pressure module, which is a pressure sensor.

[0065] In order to ensure that the sensors 9 to be coded can be transferred to the first transfer mechanism in this embodiment, a stacking unit 2002 is provided. After completing the processing of the same batch of sensors, the sensors 9 are placed one by one on the second tooling 2039 by a robot. As the number of sensors 9 placed on the second tooling 2039 gradually increases, the pressure of the second tooling 2039 on the pressure module also gradually increases. When the pressure value reaches the preset value, that is, the second tooling 2039 is full of sensors 9, the second driving mechanism drives the third slide to move on the third slide rail 2003, and drives the second tooling 2039 equipped with sensors 9 to the first transfer mechanism, so that the first transfer mechanism can move the sensors on the second tooling 2039 one by one to the coding mechanism 50 for coding.

[0066] The first transplanting mechanism includes a first column 2004, a horizontal platform 2006, a fourth slide 2005, a fourth slide seat 2007, a seventh driving mechanism and a first clamping assembly.

[0067] The first column 2004 is fixed on the top of the detection platform 45 , and the third slide rail 2003 is located between two first columns 2004 , and the horizontal platform 2006 is fixed on the top of the first columns 2004 .

[0068] The fourth slide 2005 is fixed on the horizontal platform 2006 , the fourth slide seat 2007 is slidably connected to the fourth slide 2005 , and the output end of the seventh driving mechanism is connected to the fourth slide seat 2007 .

[0069] In this embodiment, in order to ensure that the first transplanting mechanism can drive the first clamping assembly to move back and forth between the stacking unit 2002 and the coding mechanism 50, so as to realize the coding of the sensors 9 stacked on the stacking unit 2002 one by one, specifically, the seventh driving mechanism is a cylinder or a hydraulic cylinder. When the seventh driving mechanism is working, the output end of the seventh driving mechanism drives the fourth slide 2007 to move on the fourth slide 2005, so that the first clamping assembly connected to the fourth slide 2005 can move back and forth between the stacking unit 2002 and the coding unit, thereby realizing automatic loading of the sensors 9 one by one.

[0070] A fifth slide 2008 is also provided on the side wall of the fourth slide 2007, a fifth slide 2009 and a sixth driving mechanism are provided on the fifth slide 2008, the fifth slide 2009 is slidably connected to the fifth slide 2008, and the output end of the sixth driving mechanism is connected to the fifth slide 2009; the fifth slide 2009 is connected to a first clamping assembly for clamping the sensor 9.

[0071] In this embodiment, in order to ensure that the first clamping component can move in the vertical direction, thereby driving the first clamping component to grab the sensor 9 placed on the stacking unit 2002 or the inkjet coding component, a fifth slide 2008 is connected to the fourth slide 2007, and the sixth driving mechanism is a cylinder or a hydraulic cylinder. When the sixth driving mechanism is working, the output end of the sixth driving mechanism drives the fifth slide 2009 to move in the vertical direction, changing the height of the second clamping component in the vertical direction, thereby ensuring that the first clamping component can smoothly remove the sensor 9 placed on the stacking unit 2002 or the inkjet coding mechanism 50.

[0072] The inkjet printer assembly includes a fixed seat 2013, a first tooling 2020 and two inkjet printers 2021. A rotating unit 2011 is provided on the top of the detection table 45. The rotating unit 2011 is a motor. The bottom of the fixed seat 2013 is connected to the rotating unit 2011. A movable disk 2018 is provided on the fixed seat 2013. The output end of the rotating unit 2011 extends vertically into the fixed seat 2013 and is connected to the movable disk 2018. The first tooling 2020 is fixed on the movable disk 2018. Two positioning grooves for placing the sensor 9 are provided on the first tooling 2020. The inkjet printer 2021 is fixed to the fixed seat 2013 through a vertical plate.

[0073] In order to enable the sensor 9 to be sprayed with code, a first tooling 2020 for placing the sensor 9 is provided in the present embodiment. The temperature sensor 9 captured can be installed on the first tooling 2020 by means of the provided transplanting assembly and the clamping assembly, and then the provided inkjet printer 2021 is used to first spray code one of the surfaces of the sensor 9. After the inkjet printer 2021 completes the spray coding of one surface of the sensor 9, the provided rotating unit 2011 is used to drive the movable disk 2018 to rotate, and the first tooling 2020 on which the sensor 9 is mounted on the movable disk 2018 rotates synchronously, so that the other surface of the sensor 9 faces the inkjet printer 2021, so that the inkjet printer continues to spray code the other surface of the sensor 9.

[0074] The set inkjet printer 2021 is a laser inkjet printer.

[0075] The side wall of the fixing seat 2013 is also provided with a convex edge 2014, the convex edge 2014 is provided with a first clamp 2015, the first clamp 2015 is provided with a first adjusting rod 2016, one end of the first adjusting rod 2016 is provided with a second clamp, the second clamp is provided with a second adjusting rod, one end of the second adjusting rod is provided with a third clamp, the third clamp is provided with a third adjusting rod 2023, and the third adjusting rod 2023 is provided with a first camera 2022.

[0076] In this embodiment, in order to detect whether a sensor 9 is placed in the first tooling 2020, a first camera 2022 is also provided on the fixed seat 2013. The first camera 2022 is movably connected to the convex edge 2014 on the fixed seat 2013 through the first adjusting rod 2016, the second adjusting rod and the third adjusting rod 2023, so that the position of the first camera 2022 can be adjusted according to actual conditions to ensure that the first camera 2022 can capture the image of the first tooling 2020, thereby determining whether there is a sensor 9 on the first tooling 2020.

[0077] It also includes a detection unit 2012, which includes a fixed column 2031, a movable platform 2035, a first slider 2034, a shell 2033 and a second camera 2032. The movable platform 2035 is slidably connected to the fixed column 2031, the first slider 2034 is slidably connected to the movable platform 2035, the shell 2033 is fixed on the first slider 2034, the second camera 2032 is connected to the shell 2033, and the second camera 2032 is facing the first tooling 2020.

[0078] In order to detect whether the inkjet code on the sensor 9 is qualified, a detection unit 2012 is further provided in this embodiment. The second camera 2032 can be used to capture images of the sensor 9 after inkjet coding to determine whether the inkjet code on the sensor 9 is qualified. At the same time, in order to ensure that the second camera 2032 can be accurately aligned with the sensor 9 on the first tooling 2020, a manual turntable is provided on the fixed column 2031 and the movable platform 2035. A transmission screw is provided on the manual turntable. The movable platform 2035 is connected to the transmission screw on the fixed column 2031 through a thread, and the first slider 2034 is connected to the transmission screw on the movable platform 2035 through a thread. In this way, the two manual turntables can be used to adjust the vertical and horizontal positions of the second camera 2032, thereby ensuring that the second camera 2032 can be aligned with the sensor 9 on the first tooling 2020.

[0079] During inspection, after the inkjet printer 2021 completes coding on the sensor 9 on the first tooling 2020, the first tooling 2020 is rotated 180° using the rotating unit 2011 so that the coded surface of the sensor 9 faces the second camera 2032, and the second camera 2032 is used to detect whether the coding on the sensor 9 is qualified; after the inkjet printer 2021 codes the other side of the sensor 9, the rotating unit 2011 is used to continue to rotate the first tooling 2020 180° so that the coding on the other side of the sensor 9 also faces the second camera 2032, so as to detect the coding on that side.

[0080] Since the sensors 9 to be coded need to be placed one by one on the second tooling 2039 after completing the previous process, and then the sensors 9 on the second tooling 2039 can be coded one by one, in order to avoid the previous process and the first transfer mechanism sharing a second tooling 2039 at the same time, causing mutual interference, a stacking unit 2002 is provided. When the second tooling 2039 is filled with the sensors 9 to be coded in the previous process, the eighth driving mechanism starts to work and drives the second tooling 2039 to move to the bottom of the horizontal table 2006, so that the first transfer mechanism moves the first clamping assembly to the second tooling 2039 to clamp the sensor 9 on the second tooling 2039.

[0081] The water bath heating mechanism 47 includes a heating box 241 with a heating pool, the heating box 241 is fixed on the detection table 45, and a driving unit 245 is also provided on the heating box 241. A turntable 243 is provided at the output end of the driving unit 245, and the turntable 243 is located in the heating pool of the heating box 241. The turntable 243 is provided with a plurality of mounting holes 247 for placing the sensor 9. The heating box 241 is also provided with a loading port and a unloading port. The first transplanting mechanism can drive the first clamping assembly to the loading port, and the second transplanting mechanism 48 can drive the second clamping assembly to the unloading port. The time for the mounting hole 247 of the turntable 243 located at the loading port to rotate to the unloading port is the heating time required for the sensor 9 in the heating pool.

[0082] In the prior art, when testing temperature sensors, the traditional method is to place the temperature sensors in batches in a constant temperature pool, and then take out the sensors one by one for resistance testing after the sensors are soaked for a period of time to determine whether the sensors are qualified products. However, the sensors in the constant temperature pool need to be taken out one by one before the next batch of sensors can be placed in the constant temperature pool in batches. This results in that after a new batch of sensors are placed in the constant temperature pool, it is necessary to wait for the sensors to be soaked for a specified time before the sensors can be tested. This reduces the detection efficiency of the sensors. For this reason, the technical solution is provided with a heating pool in the heating box 241. The heating pool can heat the water temperature in the pool body to a certain temperature to keep it in a certain constant temperature state, so as to heat the sensor water bath to the detection temperature. At the same time, a turntable 243 is also provided in the heating pool of the heating box 241. A plurality of mounting holes 247 are provided on the turntable 243. When testing, the sensor 9 with the test is taken out The loading port on the heating box 241 is placed in the mounting hole 247 on the turntable 243, and then the driving unit 245 is used to drive the turntable 243 to rotate a certain angle, so that the next mounting hole 247 on the turntable 243 rotates to the loading port, and the sensor 9 to be detected continues to be placed in the mounting hole 247. The driving unit 245 continues to drive the turntable 243 to rotate a certain angle, and so on, so that the sensors 9 installed on the turntable 243 rotate one by one toward the unloading port. During the rotation of the turntable 243, the heating pool performs water bath heating on the sensor 9 on the turntable 243. When the sensor 9 on the turntable 243 just rotates to the unloading port, the time that the sensor 9 is immersed in the heating pool is the water bath heating time specified for the sensor 9. Therefore, when the sensor 9 on the turntable 243 rotates to the unloading port, the sensor 9 at this position on the turntable 243 is taken out for resistance detection to determine whether the sensor 9 meets the specified accuracy requirements, thereby improving the detection efficiency of the sensor.

[0083] After the sensor 9 is heated to a specified temperature in a water bath, the second clamping assembly on the second transplanting mechanism 48 is used to take out the sensor at the discharge port of the water bath heating mechanism 47 and measure its resistance. The measured resistance value is used to determine whether the sensor 9 is a qualified product. The measured sensor 9 is then transferred to the air-drying mechanism 49, and the air-drying mechanism 49 is used to air-dry the sensor 9 to remove water stains attached to the surface. Finally, the air-dried sensor 9 is placed in the loading port of another water bath heating mechanism 47 by the second transplanting mechanism 48, and the turntable 243 is used to rotate the sensors 9 one by one and heat them in a water bath to a specified temperature. Therefore, the air-drying mechanism 49 set between the two water bath heating mechanisms 47 can remove water stains on the sensor 9, thereby avoiding the water stains attached to the surface of the sensor 9 affecting the water temperature in the heating pool, and further improving the detection accuracy of the sensor 9.

[0084] The driving unit 245 includes a second column 2413, a horizontal plate 2412, a motor 2411 and a transmission belt 249. The second column 2413 is fixed on the side wall of the heating box 241, and the horizontal plate 2412 is slidably connected to the second column 2413; two pulleys 248 are provided on the horizontal plate 13, and both ends of the transmission belt 249 are sleeved on the two pulleys 248. A rotating shaft is also provided on the turntable 243, and the rotating shaft passes through the horizontal plate 13 and is connected to one of the pulleys 248; the motor 2411 is fixed to the bottom of the horizontal plate 2412, and the output shaft of the motor 2411 passes through the horizontal plate 2412 and is connected to the other pulley 248.

[0085] In this embodiment, when it is necessary to drive the turntable 243 to rotate in the heating pool, the motor 2411 works to drive one of the pulleys 248 to rotate. When the pulley 248 rotates, it drives the other pulley 248 to rotate under the action of the transmission belt 249, thereby causing the turntable 243 to rotate in the heating pool, and gradually rotating the water bath heated sensor 9 from the loading port to the unloading port.

[0086] A sixth slide and a transmission screw are also provided on the second column 2413.
