Description

Technical Field

[0001] The present invention relates to the technical field of motor waterproof detection, and in particular to a detection device for motor waterproof. Background Art

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses an energized coil (i.e., stator winding) to generate a rotating magnetic field and acts on a rotor (such as a squirrel-cage closed aluminum frame) to form a magneto-electrical rotating torque. Electric motors are divided into DC motors and AC motors according to the power supply used. After the motor is produced, waterproof testing equipment is needed to test the waterproof performance of the motor.

[0003] The motor waterproof detection device in the prior art places the micro motor in a placement box, starts the cylinder to drive the right shell to move toward the left shell, and combines them to form a closed shell, places the micro motor in a relatively closed environment, and then starts the first motor to drive the first screw to rotate, and with the cooperation of the connecting plate, the upper shell and the lower shell are sealed and combined, and the connection between the left shell and the right shell is sealed, thereby further improving the sealing of the micro motor during detection, effectively isolating the micro motor from the external environment, avoiding being easily affected by external factors during detection, and making the detection result more accurate;

Under the guidance of the through rod 19 in the first guide groove 21, the insert plate 18 is driven to move in the slot of the lifting plate 15 toward the conveying seat 39, and then drives the lifting plate 17 at one end of the insert plate 18 to move and insert into the lifting groove 10. As the lifting plate 15 continues to move, the lifting plate 17 moves and supports to the upper groove wall of the lifting groove 10, thereby lifting the conveying seat 39 and the motor as a whole in the placement frame 7 to move to the detection position for detection work.

[0034] See also Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 7 The detection structure includes a cylinder 24 installed at the top of one side away from each other of the two side plates 3, and a detection frame 22 is installed on one end of the cylinder 24 output shaft passing through the side plate 3, one of the detection frames 22 is provided with a water spray structure, one of the detection frames 22 is provided with a sealing frame at the edge of one side away from the side plate 3, and the other detection frame 22 is provided with a sealing groove 23 at the edge of one side away from the side plate 3, and the lower inner wall of each detection frame 22 is inclined toward the side close to the side plate 3, and a lifting structure is provided between the detection frame 22 and the conveying seat 39;

[0035] The lifting structure includes four lifting bars 25 connected to the inner walls of the two detection frames 22 on the side away from each other, and four lifting frames 26 (the shape of the lifting frames 26 is as shown in FIG. 1 ) are connected to the front and rear edges of the conveying seat 39. Figure 3As shown in the figure, a limit plate 27 is installed on one side of each group of two lifting frames 26 that are away from each other. When the lifting plate 17 drives the conveying seat 39 and the motor to move upward to the position between the two detection frames 22, the cylinder 24 is started to drive the two detection frames 22 to move toward the middle, and the lifting bars 25 on the inner walls of the detection frames 22 are inserted into the corresponding lifting frames 26, so that when the two detection frames 22 move, they can automatically drive the detection frames 22 to move upward from the lifting plate 17 until they move to the middle between the two detection frames 22. In this way, as the detection frames 22 continue to move, the conveying seat 39 can be lifted to the two detection frames 22, and the two detection frames 22 can be smoothly spliced ​​together, so that the waterproof detection work can be smoothly carried out;

[0036] The water spraying structure includes a connecting tube 29 connected to the bottom of one of the detection frames 22, a water storage tank 28 is installed at the bottom end of the connecting tube 29, a water pump 31 is installed at a side of the water storage tank 28 near the bottom end, a water supply pipe 30 is connected to the water pump 31, a nozzle 32 is installed on one end of the water supply pipe 30 inserted into the detection frame 22, and a blocking structure is arranged in the connecting tube 29.

[0039] The implementation of a motor waterproof detection device according to an embodiment of the present invention is as follows: first, the first motor 4 is started to drive the rotating rod 5 and the conveyor belt 6 to rotate as a whole, and the motor in the conveying seat 39 is conveyed toward the side plate 3 for automatic loading. When the motor to be detected moves to the position between the two side plates 3 along with the conveying seat 39, the second motor 13 is started to drive the screw 14 to rotate, and the lifting plate 15 moves upward on the rotating screw 14, and drives the through rod 19 to move upward in the first guide groove 21 of the vertical plate 20. Under the guidance of the through rod 19, the slot 21 drives the insert plate 18 to move in the slot of the lifting plate 15 toward the direction close to the conveying seat 39, thereby driving the lifting plate 17 at one end of the insert plate 18 to move and insert into the lifting slot 10. As the lifting plate 15 continues to move, the lifting plate 17 moves and supports to the upper slot wall of the lifting slot 10, thereby bringing the conveying seat 39 and the motor as a whole to the detection position in the placement frame 7. Then, the cylinder 24 is started to drive the two detection frames 22 to move toward the middle, and the lifting bar 25 on the inner wall of the detection frame 22 is inserted into the lifting slot 10. The two detection frames 22 are moved into the corresponding lifting frames 26, so that when the two detection frames 22 move, they can automatically drive the detection frames 22 to move upward from the lifting plate 17 until they move to the middle between the two detection frames 22. In this way, as the detection frames 22 continue to move, the conveying seat 39 can be lifted to the two detection frames 22, and the two detection frames 22 can be smoothly spliced ​​together. Then, the water pump 31 can be started to convey the water in the water tank 28 from the water delivery pipe 30 to the nozzle 32, and the nozzle 32 sprays it toward the motor in the conveying seat 39 to The waterproof detection work is realized, and the sprayed water can flow back from the connecting tube 29 to the water storage tank 28 to realize the water recycling function. After the detection, the two detection frames 22 move away from each other, and the detected motor and conveying seat 39 are placed on the lifting plate 17 as a whole, and the second motor 13 is started to drive the screw 14 to rotate in the opposite direction. The lifting plate 17 will re-place the conveying seat 39 and the motor as a whole on the corresponding placement frame 7, and the rotating conveyor belt 6 will transport the unloaded material, so that the waterproof detection work of the motor can be realized.

[0040] The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereto.
