Description

Technical Field

[0001] The invention mainly relates to the technical field of water level sensors, and in particular to a sensor debugging device. Background Art

[0002] The water level sensor has the advantages of convenient control and simple structure, and is widely used in household or commercial washing machines and dishwashers. The working principle of the water level sensor is that the diaphragm connection component in the installation cavity is pushed by gas to change its position, and then the diaphragm connection component changes the inductance of the inductor coil, so that the change signal of the inductance is transmitted to the water level controller of the washing machine or dishwasher, and then the water level height is controlled. For example, the utility model patent with the authorization announcement number CN220602646U discloses a high-precision low-frequency water level sensor, wherein the circuit board is provided with a frequency division circuit, a power supply filter circuit, an oscillation circuit and an amplifier circuit, the output end of the power supply filter circuit and the output end of the oscillation circuit are both connected to the input end of the frequency division circuit, the output end of the frequency division circuit is connected to the input end of the amplifier circuit, and the output end of the amplifier circuit is connected to the output interface; the oscillation circuit includes a starting capacitor and an inductor coil connected in parallel, and the inductor coil is wound on a coil frame.

[0003] However, water level sensors need to undergo rigorous debugging during the production process to ensure the reliability and stability of their performance. Existing sensor debugging methods mostly use manual operations, which are inefficient, and the debugging results are easily affected by human factors, resulting in uneven product quality. In addition, traditional debugging equipment has a single function, lacks systematicity and comprehensiveness, and cannot meet the diverse debugging needs of different types of water level sensors.

[0030] Working process Loading stage: The loading conveyor belt 32 keeps running, and the sensor to be debugged is transported to the designated position. The manipulator 31 is located on one side of the loading conveyor belt 32, and it has precise positioning and grasping functions. When the sensor reaches the appropriate position, the manipulator 31 moves quickly, accurately grasps the sensor through the clamping device at its end, and then places the sensor on the placement table 24 of the adjustment table 2 of the ring conveyor 1. At this time, the placement table 24 is in the initial position, waiting to receive the sensor.

[0031] Transportation and detection adjustment stage: The circular conveyor 1 starts to operate, driving the adjustment platform 2 and the sensor placed thereon to move along the circular track at a stable speed. During the movement of the sensor, the detection camera 6 located above the adjustment platform 2 performs real-time detection of the sensor. The detection camera 6 can obtain information such as the position and posture of the sensor, and feed this information back to the control system. The control system controls the action of the rotating cylinder 22 based on the information fed back by the detection camera 6. The rotating cylinder 22 drives the placement platform 24 to rotate and adjust the angle of the sensor so that the orientation of the sensor is consistent, preparing for subsequent debugging work.

[0032] Material transfer stage: When the sensor moves to the material transfer mechanism 4 along with the circular conveyor 1, the material transfer mechanism 4 starts to work. The support column 41 is fixed on the ground or other supporting structures to provide stable support for the entire material transfer mechanism 4. The rotating cylinder 42 is installed at the upper end of the support column 41, which can drive the mounting plate 43 to rotate around the axis of the support column 41. When the clamping cylinder 45 and the clamping arm 46 rotate to the top of the placement table 24, the lifting cylinder 23 drives the placement table 24 to rise, and the clamping cylinder 45 on the mounting seat 1 44 at both ends of the mounting plate 43 extends, driving the clamping arm 46 to open and accurately clamp the sensor. Then, the rotating cylinder 42 rotates 180° to move the sensor to the top of the debugging table 51. At the same time, the sensor on the debugging table 51 can also be moved to the placement table 24.

[0033] Debugging stage: After the sensor is transferred to the debugging platform 51, the interface docking mechanism 7 starts to work. The pneumatic slide 72 at the lower end of the connecting plate 71 fixed on the frame 52 extends out, driving the mounting seat 2 73 and the analog interface 74 on the mounting seat 2 73 close to the sensor interface. When the analog interface 74 is aligned with the sensor interface, the pneumatic slide 72 continues to advance, so that the analog interface 74 and the sensor interface are accurately docked. At the same time, the air pipe docking mechanism 8 also starts to work. The motor 802 starts, driving the active synchronous pulley 803 to rotate, and the active synchronous pulley 803 drives the driven synchronous pulley 804 to rotate through the synchronous belt 805. The connecting block 806 on the synchronous belt 805 moves with the movement of the synchronous belt 805, and the connecting block 806 drives the moving block 807 to slide along the guide rail 810. The docking pipe 808 on the moving block 807 gradually approaches the sensor air pipe and finally achieves docking. At this time, the air pressure regulating mechanism 9 begins to play a role. The air compressor 93 compresses the air and then delivers it to the air tank 92 for storage, and the air tank 92 plays the role of stabilizing the air pressure. The compressed air output by the air tank 92 is adjusted to a suitable pressure by the pressure regulating valve 94, and then delivered to the docking pipe 808 through the air supply pipe 809, providing a stable air pressure for the sensor, and cooperating with the analog interface 74 for debugging.

[0034] Unloading stage: After debugging is completed, the material transfer mechanism 4 operates again to move the sensor from the debugging table 51 back to the adjustment table 2 of the ring conveyor 1. Then, the manipulator 31 at the other end of the ring conveyor 1 grabs the sensor and places it on the unloading conveyor belt 33, which transports the debugged sensor to the next process or the finished product storage area.

[0035] The above-described embodiments only express a certain implementation mode of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
