[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figures 1-5 As shown, a sensor detection system includes a frame 1, two robotic arms 2 are arranged in the middle of the frame 1, a track 3 is fixed in the middle of the frame 1, two workstations 4 are slidably arranged on the track 3, a placement platform 5 is fixed on the left workstation 4, a vision recognition component is arranged on the upper part of the placement platform 5, the vision recognition component is arranged on the drive module 6, the drive module 6 is fixed to the upper part of the frame 1, a clamp 7 is fixed on the upper part of the right workstation 4, a receiving platform 8 is fixed at the rear of the clamp 7, two detection slots 9 are opened on the clamp 7, a removal component is arranged on the middle workstation 4, a first cylinder 10 is fixedly installed on the frame 1 above the removal component, a mounting plate 11 is fixed to the output end of the first cylinder 10, two clamping components are arranged on the lower part of the mounting plate 11, the two clamping components are respectively located directly above the two detection slots 9, and the two robotic arms 2 are respectively arranged in front of the placement platform 5 and the receiving platform 8.

[0029] The visual recognition component, gripping component, drive module 6, and robotic arm 2 are all connected to an external industrial control computer via wires;

[0030] The robot arm 2 on the left places the sensor located outside the environment onto the placement platform 5. The sensor is initially tested by the vision recognition component. If it passes the test, the robot arm 2 on the right picks up the sensor and places it into the test slot 9. The first cylinder 10 drives the mounting plate 11 to descend, causing the clamping component to press the sensor for testing. If the sensor fails to pass either test, the external industrial control computer will be notified and will issue an alarm.

[0031] In this embodiment, the visual recognition component includes a drive stage 12 disposed on the drive end of the drive module 6. A second cylinder 13 is fixed to the lower part of the drive stage 12. A third cylinder 14 is fixed to the lower part of the output end of the second cylinder 13. A camera 15 is fixed to the output end of the third cylinder 14. The camera 15 is located directly above the placement stage 5.

[0032] The drive module 6 can adjust the left and right position of the drive platform 12, the second cylinder 13 can adjust the height of the camera 15, and the third cylinder 14 can adjust the front and back position of the camera 15, thereby controlling the position of the camera 15 to perform visual recognition of the sensor and upload the data to an external industrial control computer.

[0033] In this embodiment, the clamping assembly includes a first motor 16 fixed inside the mounting plate 11. A drive disk 17 is fixed to the lower part of the motor's output shaft. Multiple drive rods 18 are hinged to the lower part of the drive disk 17. A positioning component is hinged to the lower part of each drive rod 18. A pressure plate 19 fixed to the mounting plate 11 is provided below the drive disk 17. A pressure sensor 20 is provided at the lower part of the pressure plate 19. Multiple guide grooves are opened on the upper part of the pressure plate 19. A guide rod 22 is slidably arranged in each guide groove. Multiple positioning components are respectively fixed to the ends of the guide rods 22 away from the first motor 16.

[0034] In this embodiment, multiple positioning components are respectively disposed around the pressure plate 19, and there are four positioning components located on the four sides of the pressure plate 19.

[0035] In this embodiment, the positioning component includes a connecting block 23 fixed to the end of the guide rod 22 away from the first motor 16. The connecting block 23 is hinged to the lower part of the drive rod 18. The connecting block 23 is fixed to the end of the guide rod 22 away from the first motor 16. A round rod 24 is fixed to the end of the connecting block 23 away from the first motor 16. Long rods 25 are respectively inserted into the front and rear ends of the round rod 24. A roller 26 is rotatably connected between the two long rods 25. A first spring 27 is provided above the roller 26. One end of the first spring 27 is fixed to the lower part of the round rod 24, and the other end of the first spring 27 is fixed to the upper part of the long rod 25.

[0036] The first cylinder 10 drives the mounting plate 11 to descend, which in turn drives the pressure plate 19 and positioning components to descend. When the pressure plate 19 touches the sensor, the pressure sensor 20 sends a signal to the industrial control computer. The industrial control computer then controls the first motor 16 to run, which in turn drives the drive disc 17 to rotate. The drive disc 17 drives the drive rod 18 to move, thereby moving the positioning components towards the pressure plate 19. This causes the four positioning components to fit around the sensor and clamp it. At this time, the pressure plate 19 continues to descend. The positioning components prevent the sensor from moving. The roller 26 in the positioning components fits against the sensor. As the pressure plate 19 moves downward, the roller 26 rotates and descends together with the sensor. When the roller 26 presses against the clamp 7... Afterwards, the pressure plate 19 continues to descend, and the two long rods 25 insert into the round rod 24 by increasingly larger lengths until the long rods 25 press against the round rod 24 and squeeze the first spring 27. At this time, the pressure plate 19 moves to the bottom position. During this process, the pressure sensor 20 will continuously detect the pressure of the squeeze sensor. The pressure is set to a fixed value. If the pressure exceeds the fixed value of the pressure sensor 20 during this period, the industrial control computer will receive the information and control the first cylinder 10 to stop running and remind the staff to come and check. If the pressure sensor 20 does not exceed the fixed value after the pressure plate 19 moves to the lowest position, the first cylinder 10 will rise, and the first spring 27 will push the roller 26 to reset. The sensor is not faulty, and the removal assembly will collect the sensor and send it to the receiving table 8.

[0037] In this embodiment, the removal component includes a first placement plate 28 and a second placement plate 29 slidably disposed in the detection groove 9. Reinforcing blocks 30 are provided on both the front and rear sides of the first placement plate 28 and the second placement plate 29. A reinforcing groove 31 communicating with the detection groove 9 is opened inside the clamp 7. The first placement plate 28 and the second placement plate 29 are slidably disposed on the reinforcing groove 31 through the reinforcing blocks 30. The longitudinal section of the first placement plate 28 near the second placement plate 29 is convex, and the longitudinal section of the second placement plate 29 near the first placement plate 28 is concave. The first placement plate 28 and the second placement plate 29 are both disposed on the adjustment component.

[0038] The cooperation between the reinforcing block 30 and the reinforcing groove 31 makes the movement of the first placement plate 28 and the second placement plate 29 more stable. The concave shape of the second placement plate 29 and the convex shape of the first placement plate 28 make the pressure-bearing capacity stronger when the first placement plate 28 and the second placement plate 29 are in cooperation.

[0039] In this embodiment, the adjustment assembly includes a conveying cavity 32 opened inside the clamp 7, the conveying cavity 32 is connected to the detection groove 9, a second motor 33 is fixed inside the conveying cavity 32, a first connecting shaft 34 is fixed to the output end of the second motor 33, two first synchronous pulleys 35 are rotatably connected inside the conveying cavity 32, the two first synchronous pulleys 35 are connected by a first synchronous belt 36, one of the first synchronous pulleys 35 is fixed to the first connecting shaft 34, the other first synchronous pulley 35 is fixed to the first reciprocating screw 37, the first synchronous pulley 35 fixed to the first reciprocating screw 37 is rotatably connected to the inner wall of the conveying cavity 32, the other end of the first reciprocating screw 37 is fixedly connected to a second reciprocating screw 40 through a mating rod 38, the other end of the second reciprocating screw 40 is rotatably connected to the inner wall of the conveying cavity 32, a first placement plate 28 and a second placement plate 29 are respectively threaded to the second reciprocating screw 40 and the first reciprocating screw 37, and a conveying assembly is fixed to the end of the first connecting column away from the second motor 33;

[0040] The second motor 33 drives the first connecting shaft 34 to rotate, which in turn drives the first synchronous pulley 35 to rotate. The first synchronous belt 36 causes the two first synchronous pulleys 35 to rotate together, which in turn drives the first reciprocating screw 37 and the first connecting column to rotate. The first reciprocating screw 37 drives the second reciprocating screw 40 to rotate through the mating rod 38. The threads on the first reciprocating screw 37 and the second reciprocating screw 40 are in opposite directions. The first reciprocating screw 37 and the second reciprocating screw 40 can drive the first placement plate 28 and the second placement plate 29 to move towards each other. When the sensor needs to fall from the detection slot 9, the first placement plate 28 and the second placement plate 29 move away from each other, causing the sensor to fall onto the conveying assembly. Then the first reciprocating screw 37 and the second reciprocating screw 40 continue to rotate and reclose.

[0041] In this embodiment, the conveying assembly includes two second synchronous pulleys 41, one of which is fixed to the end of the first connecting column, and the other is rotatably connected to the inner wall of the conveying cavity 32. The two second synchronous pulleys 41 are connected by a second synchronous belt 39. A conveying roller 42 is fixed on each of the two second synchronous pulleys 41, and a conveying belt 43 is connected to the two conveying rollers 42.

[0042] The rotation of the first connecting column drives the rotation of a second synchronous pulley 41. The second synchronous belt 39 causes the two second synchronous pulleys 41 to rotate, thereby driving the conveyor roller 42 to rotate and the conveyor belt 43 to rotate, enabling the sensor falling from the detection groove 9 to be transported.

[0043] Preferably, a plurality of push plates 44 are fixed on the outer side wall of the conveyor belt 43.

[0044] In this embodiment, a plurality of push plates 44 are fixed on the outer side wall of the conveyor belt 43. The length between each pair of push plates 44 is greater than the length of the sensor, which can ensure that the sensor is moved.

[0045] In this embodiment, the rear of the conveying cavity 32 is connected to the outside, and the rear of the clamp 7 is provided with an inclined plate 45, and the receiving platform 8 of the inclined plate 45 is provided at the outlet end of the inclined plate 45.

[0046] The sensor delivered from the conveying chamber 32 will land on the inclined plate 45 and then slide into the receiving table 8.

[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
