[0019] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] like Figure 1-9The temperature sensor air tightness detection device shown comprises a detection platform 1 and a testing machine 2 arranged on the detection platform 1. The testing machine 2 mainly seals and squeezes the upper mold 6 and the lower mold 5 together, and then injects the test gas between the upper mold 6 and the lower mold 5. When the inflation is completed, if the temperature sensor probe has no leakage, the filled air pressure will remain stable (the space between the upper mold 6 and the lower mold 5 is fixed, and the volume of the temperature sensor probe is also fixed, so the injected test gas is also fixed. When too much gas is filled, a defective temperature sensor probe can be found). If the temperature sensor probe leaks, since the leakage point is generally small, the air intake will also be slow, so it will be monitored that it is still in a continuous inflation state after reaching the pre-filling state, thereby realizing the air tightness detection of the temperature sensor. The top of the detection platform 1 is rotatably connected to a disk 3, and the top of the disk 3 is equidistantly fixedly connected to four lower molds 5, and the tops of the four lower molds 5 are opened on both sides. An opening 7 is provided, and the setting of the opening 7 facilitates the loading and unloading of the temperature sensor probe. The output end of the mobile mechanism on the testing machine 2 is fixedly connected to the upper mold 6. An inwardly sunken groove 9 is provided on the top of the testing table 1, and the sliding position of the U-shaped plate 10 can be limited by the groove 9. The U-shaped plate 10 is slidably connected to the inner side of the groove 9, and a pair of transmission rollers 12 are rotatably connected to the inner side of the U-shaped plate 10. A conveyor belt 13 is transmission-connected between the transmission rollers 12, and a plurality of placement grooves 28 for placing the temperature sensor probe are equidistantly provided on the outer wall of the conveyor belt 13. A conveying motor 29 is fixedly connected to the side wall of the U-shaped plate 10, and the output end of the conveying motor 29 passes through the inner side of the U-shaped plate 10 and is fixedly connected to the side wall of one of the transmission rollers 12. A storage frame 30 for storing the temperature sensor probe is fixedly connected to the top of the U-shaped plate 10 and located above one of the placement grooves 28. The setting of the storage frame 30 facilitates the storage of more temperature sensor probes to be tested. The top of the U-shaped plate 10 is fixedly connected to a U-shaped top frame 15, a storage groove is provided on the inner side of the U-shaped plate 10 and at a position corresponding to the opening 7, a push plate 17 is provided on the inner side of the storage groove, and the top of the push plate 17 is slidably connected to the inner side of the U-shaped top frame 15, a through groove 18 is provided on the front side of the U-shaped top frame 15, a pull rope 19 is fixedly connected to the side wall of the push plate 17, the front end of the side wall of the U-shaped plate 10 is slidably connected to the side plate 21, the other end of the pull rope 19 passes through the through groove 18 and is fixedly connected to the side wall of the side plate 21, the top of the test bench 1 is fixedly connected to an electric telescopic cylinder 14, the output end of the electric telescopic cylinder 14 is fixedly connected to the side wall of the side plate 21, and a fixed distance limiting mechanism for limiting the sliding position of the side plate 21 is provided on the test bench 1; A rotating motor 4 is fixedly connected to the top of the detection table 1, and the output end of the rotating motor 4 passes through the top of the detection table 1 and is fixedly connected to the bottom of the disc 3. A feeding trough 11 is provided on the top of the disc 3 and next to the lower mold 5. The feeding trough 11 avoids hindering the U-shaped plate 10 from moving to the disc 3 for loading. A lower opening 16 is provided on the outer wall of the U-shaped plate 10 and at a position corresponding to the feeding trough 11. The lower opening 16 avoids affecting the temperature sensor probe on the conveyor belt 13 from moving out for loading. A reset spring 35 is fixedly connected between the inner side of the U-shaped top frame 15 and the side wall of the push plate 17. The reset spring 35 facilitates the push plate 17 to be quickly reset when resetting. When performing an airtight test on the temperature sensor probe, firstly, the temperature sensor probe to be tested is swung in the storage frame 30 in sequence. At this time, the lowest temperature sensor probe will fall into the placement slot 28 on the conveyor belt 13 (when used for the first time, the temperature sensor probe to be tested can be placed in other placement slots 28 and in the lower mold 5 to be screwed into the bottom of the test machine 2, which can reduce the idle running time of the device), and then the test machine 2 is controlled to start to seal and squeeze the upper mold 6 and the lower mold 5 together, and the airtight test is performed on the temperature sensor probe in the lower mold 5. After the test is completed, the test machine 2 is controlled to drive the upper mold 6 to reset, and then the rotary motor 4 is controlled to start and drive the disc 3 to rotate, so as to screw the lower mold 5 after the test is completed out from under the test machine 2, and at the same time, the lower mold 5 with the temperature sensor probe to be tested is rotated to under the test machine 2, and then the test machine 2 is controlled to start and repeat the above operation to perform the test; At the same time, the electric telescopic cylinder 14 can be controlled to start driving the side plate 21 to move. Since the side plate 21 cannot move alone under the action of the fixed-distance limiting mechanism at this time, the side plate 21 and the U-shaped plate 10 will slide inside the groove 9 under the thrust of the electric telescopic cylinder 14, so that the U-shaped plate 10 moves to the loading trough 11. At this time, the placement groove 28 on the conveyor belt 13 is aligned with the opening 7, and the limiting rod 31 on the fixed-distance limiting mechanism moves out from the limiting plate 34, thereby releasing the restriction on the side plate 21, and the U-shaped plate 10 is resisted by the groove 9 and cannot continue to slide backward. Therefore, under the thrust of the electric telescopic cylinder 14, the side plate 21 is driven to slide on the side wall of the U-shaped plate 10, and the upper spring 23 is gradually compressed, and the pull rope 19 is driven to move when the side plate 21 moves; Thereby, under the guidance of the upper guide roller 26 and the lower guide roller 27, the push plate 17 is pulled to slide on the inner side of the U-shaped top frame 15, so that the push plate 17 slides out of the storage groove and slides into the placement groove 28, and the reset spring 35 is gradually compressed, so that the temperature sensor probe in the placement groove 28 is pushed out from the placement groove 28 and pushed into the lower mold 5 through the opening 7 until the temperature sensor probe is completely pushed into the lower mold 5, and then the electric telescopic cylinder 14 is controlled to move in the reverse direction for reset, and then the above operation is repeated in the reverse direction for reset. After the push plate 17 is reset, it is necessary to control the transmission motor 29 to start and drive a transmission roller 12 to rotate, thereby driving the conveyor belt 13 to transmit between the two transmission rollers 12, and the empty placement groove 28 is rotated out and the push cylinder 14 is connected to the push cylinder 14. The plate 17 corresponds to the position, and in this process, the placement slot 28 at the bottom of the storage frame 30 will move out of the storage frame 30, and then the surface of the conveyor belt 13 will squeeze the temperature sensor probe at the bottom of the storage frame 30 to prevent the temperature sensor probe in the storage frame 30 from slipping out. Then, when the empty placement slot 28 rotates to the bottom of the storage frame 30, the conveying motor 29 is controlled to stop running. At the same time, the squeezing of the temperature sensor probe at the bottom of the storage frame 30 is released, and then the temperature sensor probe in the storage frame 30 falls into the empty placement slot 28 under its own gravity. Finally, after the U-shaped plate 10 is reset and the testing machine 2 is completed, the rotating motor 4 can be controlled to start, and this process is repeated to achieve automatic detection of the temperature sensor probe.

[0022] In order to improve the sealing during the detection process, a lower plate 8 is fixedly connected to the bottom of the upper mold 6 and at a position corresponding to the opening 7, and the lower plate 8 is used to facilitate sealing the opening 7. An upper sealing ring 24 is fixedly connected to the bottom of the upper mold 6 and the lower plate 8, and a lower sealing ring 25 is fixedly connected to the lower mold 5 and the top of the opening 7. Through the arrangement of the upper sealing ring 24 and the lower sealing ring 25, the sealing performance of the upper mold 6 and the lower mold 5 when they are connected can be increased, thereby improving the airtight detection effect of the temperature sensor probe and increasing the accuracy of the detection data.

[0023] In order to improve the stability of the device during operation, a rear plate 22 is fixedly connected to the rear end of the side wall of the U-shaped plate 10, and a pair of upper springs 23 are fixedly connected between the rear plate 22 and the side plate 21. Through the arrangement of the rear plate 22 and the upper springs 23, the electric telescopic cylinder 14 can push the side plate 21 to move separately, and during the feeding process of the temperature sensor probe, the upper spring 23 is squeezed, thereby squeezing the U-shaped plate 10, ensuring that the position of the U-shaped plate 10 remains stationary, avoiding the misalignment of the placement groove 28 and the lower mold 5, which affects the normal feeding of the device; An upper opening 20 is provided at the top of the U-shaped plate 10 and on the side away from the U-shaped top frame 15. An upper guide roller 26 is rotatably connected to the inner side of the upper opening 20, and a pair of lower guide rollers 27 are rotatably connected to the inner side of the through groove 18. The pull rope 19 passes through the outer walls of the upper guide roller 26 and the lower guide roller 27 respectively. The arrangement of the upper opening 20, the upper guide roller 26 and the lower guide roller 27 can guide the sliding of the pull rope 19 and prevent the pull rope 19 from contacting the corner of the through groove 18, thereby affecting the service life of the pull rope 19.

[0024] The cam 32 is a substantially parallelogram of the cam 32. The cam 32 is a substantially parallelogram of the cam 32. The cam 32 is a substantially parallelogram of the cam 32. The cam 32 is a substantially parallelogram of the cam 32. The cam 32 is a substantially parallelogram of the cam 32. When the electric telescopic cylinder 14 pushes the side plate 21 to move and automatically loads the temperature sensor probe, the limit rod 31 will be driven to slide on the side wall of the limit plate 34. At this time, the limit plate 34 will squeeze the limit rod 31, so that the limit rod 31 is inserted into the inner side of the limit groove 32, thereby limiting the sliding position of the side plate 21 to avoid pushing the side plate 21 to move, causing the push plate 17 to shift and affecting the normal loading of the subsequent device. Subsequently, when the U-shaped plate 10 moves to the end of the groove 9, the limit rod 31 at this time will move out from the limit plate 34, and the limit rod 31 that loses the squeeze will slide out of the limit groove 32 under the elastic force of the lower spring 33, thereby releasing the sliding restriction of the side plate 21, so that the push plate 17 and the side plate 21 can be driven to move under the drive of the electric telescopic cylinder 14, thereby realizing automatic loading of the temperature sensor probe, and finally repeating the above operation in reverse when resetting.

[0025] In order to push out the temperature sensor probe that has been tested in the lower mold 5 during the loading process, a discharge plate 39 is provided at the rear side of the U-shaped plate 10, the bottom of the discharge plate 39 is flush with the bottom end of the lower mold 5, an L-shaped plate 40 is fixedly connected between the top of the discharge plate 39 and the top of the side plate 21, a discharge trough 36 is obliquely opened at the rear side of the top of the detection platform 1 and at a position corresponding to one of the loading troughs 11, a placing frame 37 is provided at the rear side of the detection platform 1 and at a position corresponding to the discharge trough 36, and a material receiving frame 38 is provided on the placing frame 37; When the electric telescopic cylinder 14 pushes the side plate 21 to drive the push plate 17 to load the material, the side plate 21 will slide on the side wall of the U-shaped plate 10, thereby driving the L-shaped plate 40 and the discharge plate 39 to move, and then driving the discharge plate 39 to move into the lower mold 5 moved out from the bottom of the upper mold 6, so that the discharge plate 39 passes through the opening 7 to push the temperature sensor probe after detection out of the lower mold 5, and then the temperature sensor probe falls into the discharge trough 36, and then slides into the receiving frame 38 by the temperature sensor probe's own gravity (a sponge pad can be set at the bottom of the receiving frame 38 to reduce damage to the temperature sensor probe when it falls), thereby realizing automatic material removal of the temperature sensor probe.
