[0029] The visual recognition component, the clamping component, the drive module 6 and the manipulator 2 are all connected to an external industrial computer through wires;

[0030] The sensor located outside is placed on the placement table 5 by the manipulator 2 on the left side, and the sensor is preliminarily tested by the visual recognition component. If it is qualified, the sensor is picked up by the manipulator 2 on the right side and placed in the test slot 9. The first cylinder 10 drives the mounting plate 11 to descend and drives the clamping component to press the sensor for testing. During the two tests, if the sensor is found to be unqualified at any time, it will be fed back to the external industrial computer, and the external industrial computer will alarm.

[0031] In this embodiment, the visual recognition component includes a driving platform 12 disposed on the driving end of the driving module 6, a second cylinder 13 is fixed to the lower part of the driving platform 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, and the camera 15 is located directly above the placement platform 5;

[0032] The driving module 6 can adjust the left and right position of the driving platform 12, the second cylinder 13 can adjust the height position 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 on the sensor and upload the data to an external industrial computer.

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

[0034] In this embodiment, a plurality of positioning components are respectively disposed around the pressing plate 19 . There are four positioning components in number, which are located on four sides of the pressing plate 19 .

[0035] In this embodiment, the positioning assembly 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 driving 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, and a long rod 25 is respectively inserted at the front and rear ends of the round rod 24, and a roller 26 is rotatably connected between the two long rods 25. A first spring 27 is arranged 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, and the mounting plate 11 drives the pressing plate 19 and the positioning assembly to descend. When the pressing plate 19 touches the sensor, the pressure sensor 20 sends a signal to the industrial computer, and the industrial computer controls the first motor 16 to run. The operation of the first motor 16 drives the driving disk 17 to rotate, and the driving disk 17 drives the driving rod 18 to move, thereby driving the positioning assembly to move toward the pressing plate 19, so that the four positioning assemblies fit around the sensor to clamp the sensor. At this time, the pressing plate 19 continues to descend, and the positioning assembly can prevent the sensor from moving. The roller 26 in the positioning assembly fits the sensor. When the pressing plate 19 moves downward, the roller 26 fits the sensor to rotate and descend together. When the roller 26 presses against the clamp 7 After that, the pressing plate 19 continues to descend, and the lengths of the two long rods 25 inserted into the round rod 24 become longer and longer until the long rods 25 support the round rod 24 and squeeze the first spring 27. At this time, the pressing plate 19 moves to the bottommost position. During this process, the pressure sensor 20 will continuously detect the pressure of the squeezing 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 computer will control the first cylinder 10 to stop running after receiving the information, and remind the staff to come for inspection. If the value of the pressure sensor 20 does not exceed the fixed value after the pressing plate 19 moves to the lowest position, the first cylinder 10 rises, and the first spring 27 pushes the roller 26 to reset. The sensor is fine, and the removal component 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 slot 9, and reinforcement blocks 30 are disposed on both the front and rear sides of the first placement plate 28 and the second placement plate 29. A reinforcement slot 31 connected to the detection slot 9 is provided inside the fixture 7. The first placement plate 28 and the second placement plate 29 are slidably disposed on the reinforcement slot 31 through the reinforcement block 30. The longitudinal section of the first placement plate 28 on the side close to the second placement plate 29 is convex, and the longitudinal section of the second placement plate 29 on the side close to 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 can make the first placement plate 28 and the second placement plate 29 move more stably. The concave shape of the second placement plate 29 and the convex shape of the first placement plate 28 can make the first placement plate 28 and the second placement plate 29 have a stronger pressure-bearing capacity when they cooperate.

[0040] The operation of the second motor 33 drives the first connecting shaft 34 to rotate, and the first connecting shaft 34 drives the first synchronous wheel 35 to rotate. The first synchronous belt 36 makes the two first synchronous wheels 35 rotate together, and the two first synchronous wheels 35 drive 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 matching 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 toward 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, so that the sensor falls on the conveying assembly, and then the first reciprocating screw 37 and the second reciprocating screw 40 continue to rotate and close again.

[0041] In this embodiment, the conveying assembly includes two second synchronous wheels 41, one of which is fixed to the end of the first connecting column, and the other second synchronous wheel 41 is rotatably connected to the inner wall of the conveying cavity 32.

[0042] The rotation of the first connecting column drives a second synchronous wheel 41 to rotate, and the second synchronous belt 39 makes the two second synchronous wheels 41 rotate, thereby driving the conveying roller 42 to rotate, driving the conveying belt 43 to rotate, so that the sensor dropped from the detection slot 9 can 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 , and the length between every two push plates 44 is greater than the length of the sensor, which can ensure that the sensor can be driven to move.

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