Description

Technical Field

[0001] The utility model relates to the technical field of sensor testing, and specifically relates to a sensor testing and re-inspection device. Background Technique

[0002] Before leaving the factory, pressure sensors are usually tested and stability tested to evaluate the stability of the working state of the pressure sensor under fixed environmental conditions, and to ensure that the quality and performance of the pressure sensor meet the factory standards.

[0003] In the related art, when testing a pressure sensor, it is basically possible to conveniently position and place it manually. However, manually placing the pressure sensor is not conducive to the efficiency of continuous detection. If the pressure sensor needs to be retested, the detection efficiency of the pressure sensor will be further slowed down. If there are unqualified pressure sensors, they also need to be manually picked out, which is not conducive to the multiple testing of the pressure sensor. Content of the Utility Model

[0004] The purpose of the utility model is to provide a sensor testing and re-inspection device to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A sensor testing and re-inspection device, including a detection table, a turntable and a retaining ring are installed on the detection table. A plurality of placement holes are provided on the surface of the turntable for placing sensors. The retaining ring can prevent the sensors from falling out of the placement holes to ensure that the lower presser accurately presses the sensors;

[0006] A plurality of lower pressers are provided and installed on the edge of the surface of the detection table and arranged in a ring. The lower pressers are used to apply pressure to the sensors, which can realize multiple tests of the sensors, simplify the test process, and improve the detection efficiency;

[0007] A first bracket is installed on the detection table, a servo motor is installed on the first bracket, an assembly bar is installed at the output end of the servo motor, a first cylinder is installed on the assembly bar, and a suction cup is installed at the lower part of the first cylinder. The suction cup picks out unqualified sensors to realize automatic rejection of sensors, and the detection efficiency is high.

[0008] Further, a blanking port is provided on the surface of the detection table. The turntable drives the sensors to be discharged from the blanking port through the placement holes, and a conveyor belt is used to pick up the qualified sensors for the next process.

[0009] Further, the lower presser includes a second bracket and a second cylinder installed on the second bracket. A pressing block is installed at the lower end of the second cylinder. The size of the pressing block corresponds to that of the sensor, and the pressing block can be replaced to adapt to more sensors.

[0010] Further, a handle screw is screwed on the surface of the assembly bar. A universal ball is installed at the lower end of the handle screw, and the universal ball is in rolling contact with the first bracket, which can assist in supporting the assembly bar and make the rotation of the assembly bar more stable.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: The sensor is sent into the placement hole of the turntable through the conveyor belt. When the driving motor drives the turntable to rotate, the turntable moves the sensor under the pressing block. The second cylinder drives the pressing block to apply pressure to the sensor. By setting multiple pressing blocks, multiple tests of the sensor can be realized. When an unqualified sensor appears, the turntable moves the unqualified sensor under the suction cup. The first cylinder drives the suction cup to move down to suck the sensor, and the servo motor rotates to pick out the unqualified sensor. For the continuous testing and selection of sensors, the efficiency is higher. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0017] Embodiment:

[0018] Please refer to Figures 1-3, the present utility model provides a technical solution: a sensor testing and rechecking device, including a detection table 1, on which a turntable 6 and a retaining ring 5 are installed. A number of placement holes 17 are provided on the surface of the turntable 6 for placing sensors. The retaining ring 5 has a notch, and a conveyor belt 20 is installed on the detection table 1. The conveyor belt 20 feeds the sensors into the notch to ensure that the rotation of the notch can drive the movement of the sensors;

[0019] Lower presses, several lower presses are provided and installed on the edge of the surface of the detection table 1 and arranged in a ring. The lower presses are used to apply pressure to the sensors. The ring arrangement can set multiple lower presses to perform multiple tests on the sensors;

[0020] A first bracket 10 is installed on the detection table 1, and a servo motor 11 is installed on the first bracket 10. The output end of the servo motor 11 is installed with an assembly bar 12, and a first cylinder 13 is installed on the assembly bar 12. A suction cup 14 is installed at the lower part of the first cylinder 13. The suction cup 14 picks out unqualified sensors. The servo motor 11 drives the assembly bar 12 to rotate, and the sensors can be placed outside the detection table 1.

[0021] In this embodiment, as Figure 2 shown, a discharge opening 18 is provided on the surface of the detection table 1. The turntable 6 drives the sensors to be discharged from the discharge opening 18 through the placement holes 17. A conveyor belt 20 is arranged below the discharge opening 18. The qualified sensors move to the disposal of the discharge opening 18 and fall onto the conveyor belt 20, which is convenient for collecting the sensors.

[0022] In this embodiment, as Figure 1 shown, a driving motor 2 is installed below the detection table 1. The output end of the driving motor 2 is installed with a turntable 3, and a bending frame 4 is installed between the turntable 3 and the turntable 6. The driving motor 2 drives the turntable 6 to rotate through the turntable 3 and the bracket. When testing the sensors, the driving motor 2 controls the turntable 6 to stop rotating to achieve the precise displacement of the sensors.

[0023] In this embodiment, as Figure 1 shown, the lower press includes a second bracket 7 and a second cylinder 8 installed on the second bracket 7. A pressure block 9 is installed at the lower end of the second cylinder 8. The size of the pressure block 9 corresponds to the size of the sensor. The pressure block 9 is replaced for different sizes of sensors to adapt to the testing of various sensors.

[0024] In this embodiment, as Figure 1 shown, a handle screw 16 is screwed on the surface of the assembly bar 12. A universal ball 15 is installed at the lower end of the handle screw 16, and the universal ball 15 is in rolling contact with the first bracket 10. By screwing the handle screw 16, the universal ball 15 can be adjusted to tightly press against the first bracket 10 to better support the assembly bar 12.

[0025] In this embodiment, as Figure 1 shown, reinforcing plates 19 are welded at the bending parts of the first bracket 10 and the second bracket 7, improving the structural strength of the first bracket 10 and the second bracket 7 and ensuring stable supporting effect.

[0026] Specifically, in use, two conveyor belts 20 are installed on the upper and lower surfaces of the detection table 1. As Figure 2 shown, the conveyor belt 20 on the right side sends the sensors into the placing holes 17. At the same time, the driving motor 2 drives the turntable 3 to rotate, aligning the empty placing holes 17 with the sensors, and the turntable 3 can continuously pick up the sensors to be tested transported by the conveyor belt 20. The turntable 3 moves the sensors below the pressing block 9. At this time, the conveyor belt 20 and the driving motor 2 stop operating. The second cylinder 8 drives the pressing block 9 to move downward to apply pressure to the sensors. After the test is completed, the conveyor belt 20 and the driving motor 2 continue to operate. When unqualified sensors appear, the turntable 3 moves the sensors below the suction cup 14. At this time, the first cylinder 13 drives the suction cup 14 to move downward to take out the unqualified sensors from the placing holes 17. The servo motor 11 drives the first cylinder 13 to rotate circumferentially through the assembly bar 12, so that the suction cup 14 moves the sensors outside the detection table 1, picking out the unqualified sensors. The qualified sensors are moved to the position of the blanking port 18 by the turntable 3, and the sensors fall onto the conveyor belt 20 on the left side through the blanking port 18, completing the transfer of the qualified sensors.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
