Description

Technical Field

[0001] The present invention is applied to the technical field of electric toothbrush detection, and particularly relates to a fully automatic detection device for an electric toothbrush and a detection method thereof. Background Art

[0002] An electric toothbrush uses the rapid rotation or vibration of the motor to produce high-frequency vibrations in the brush head, instantly breaking down the toothpaste into fine foam and deeply cleaning the gaps between teeth. At the same time, the vibration of the bristles can promote blood circulation in the mouth and have a massage effect on the gum tissue.

[0003] At present, electric toothbrushes have been widely used in the market and are deeply loved by consumers. Electric toothbrushes also need to undergo a series of tests before they are produced and shipped. The current tests include testing the air tightness of the toothbrush handle, whether vibration will be generated when the toothbrush head is inserted into the toothbrush handle, whether the toothbrush handle started by human touch will vibrate, and whether three vibrations will be generated when the toothbrush head is loaded to about 330N. At present, except for the air tightness test, which has automated testing equipment, the other vibration tests are all manual tests. Specifically, the electric toothbrush is charged and started, and then the toothbrush handle is held by hand to feel whether vibration is generated, and then the toothbrush head is inserted to feel whether vibration is generated. Finally, the load device is used to simulate the load on the toothbrush head, and then the human hand is used to feel whether vibration is generated. The above tests all need to be tested by human touch, which not only has a certain slow production efficiency, but also after a long period of manual testing, the hands may become numb and insensitive to vibration, which affects the detection effect.

[0052] S4. The carrier 3 is transported to the touch detection mechanism 7 through the circular conveying mechanism 2, and the second charging component 72 charges the electric toothbrush 1a. Then the first driver 731 drives the coil induction connector 732 to insert into the connector 1a2, and the first pickup 733 is used to pick up whether vibration audio is generated when inserted. If no audio is generated, it is an inductive faulty product. If there is audio, it is a qualified product. Then the first lifting mechanism 74 drives the conductive silicone belt 76 to press down to the toothbrush handle 1a1, and continues to use the first pickup 733 to pick up whether vibration audio is generated when the conductive silicone simulates a human hand touching the toothbrush handle 1a1. If no audio is generated, it is a contact faulty product. If there is audio, it is a qualified product.

[0053] S5.

If no audio is generated, it is a load fault product, and if there is audio, it is a qualified product;

[0054] S6. If the products detected in the above steps are all qualified, they will be returned to the unloading station through the ring conveying mechanism 2 for manual unloading. If they are faulty products, they will be collected by the defective product collection mechanism 9, and the specific fault problem will be displayed through the corresponding fault display light.
