Description

Technical Field

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

[0002] An electric toothbrush uses the rapid rotation or vibration of the electric 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, other vibration tests are 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 toothbrush head is loaded through a load device to simulate the load, and then the human hand feels whether vibration is generated. The above tests all need to be tested by human touch, which not only has a certain degree of slow production efficiency, but also after a long period of manual testing, the hands may become numb and insensitive to vibration, resulting in affected detection results.

[0015] S1. The carrier is transported to the first incoming material sensor via the circular conveying mechanism. After the first incoming material sensor senses the incoming material, the first blocking lifter rises to block the carrier from continuing to be transported on the circular conveying mechanism. The electric toothbrush is manually placed in the carrier. Then, the first lifting device lifts the carrier to the limit plate.

The toothbrush head docking driver then inserts the test toothbrush head into the connector. The third lifting mechanism then drives the toothbrush head load plate downward to press the test toothbrush head. The second pickup detects the audio generated when the toothbrush head load plate is loaded onto the test toothbrush head. If no audio is generated, the toothbrush head is a faulty load product. If audio is generated, the toothbrush head is a qualified product.

[0020] S6. If the products detected in the above steps are qualified, they will be returned to the unloading station through the ring conveying mechanism for manual unloading.

Then the handle pushes the positioner 44 to extend and push the top of the toothbrush handle 1a1, thereby performing a reference positioning on the electric toothbrush 1a in the carrier 3. Then the height of the connector 1a2 is detected by the distance sensor 45.

[0052] S4. The carrier 3 is transported to the touch detection mechanism 7 via the circular conveying mechanism 2. The second charging assembly 72 charges the electric toothbrush 1a. The first driver 731 then drives the coil induction connector 732 to insert into the connector 1a2. The first pickup 733 detects whether vibration audio is generated during insertion. If no audio is generated, the toothbrush is faulty due to induction. If audio is generated, the toothbrush is qualified. The first lifting mechanism 74 then drives the conductive silicone belt 76 downward onto the toothbrush handle 1a1. The first pickup 733 then detects whether vibration audio is generated when the conductive silicone simulates a human hand touching the toothbrush handle 1a1. If no audio is generated, the toothbrush is faulty due to contact. If audio is generated, the toothbrush is qualified.

[0053] S5. The carrier 3 is transported to the toothbrush head load detection mechanism 8 via the circular conveying mechanism 2. The second lifting mechanism 84 drives the pressing head 89 to press the electric toothbrush 1a into the carrier 3. Simultaneously, the third charging assembly 81 charges the electric toothbrush 1a. The toothbrush head docking driver 82 then inserts the test toothbrush head 83 into the connector 1a2.

The second pickup 812 detects whether an audio signal is generated when the toothbrush head load plate 811 is loaded onto the test toothbrush head 83. If no audio signal is generated, the toothbrush head is faulty. If audio signal is generated, the toothbrush head is qualified.

[0054] S6. If the products detected in the above steps are 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.
