Description

Technical Field

[0001] This utility model relates to a vibration testing device, and more particularly to a vibration testing device for electric toothbrushes. Background Technology

[0002] Electric toothbrushes use the rapid rotation or vibration of a motor core to generate high-frequency vibrations in the brush head, instantly breaking down toothpaste into fine foam that deeply cleans between teeth. At the same time, the vibration of the bristles promotes blood circulation in the mouth and has a massaging effect on the gum tissue.

[0003] Electric toothbrushes are now widely used in the market and are very popular with consumers. However, electric toothbrushes need to undergo a series of tests before leaving the factory. For example, the toothbrush handle needs to be tested to see if it vibrates when the toothbrush head is inserted. After the toothbrush head is inserted, it needs to be tested to see if it vibrates when the load on the toothbrush head reaches a set value. Traditionally, the toothbrush head is manually inserted and the vibration is detected by human hearing and touch. The load test requires the electric toothbrush to be placed in a specific load device to apply the load force, and then the vibration is determined by human hearing and touch. The above tests involve a lot of human factors and are prone to false positives. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a vibration testing device for electric toothbrushes with a high degree of automation and accurate test results.

[0020] like Figures 1 to 7As shown, in this embodiment, the present invention includes a workbench, on which a carrier 1 is mounted, and a toothbrush handle 2 is placed. A toothbrush head drive mounting assembly 3 is mounted at one end of the carrier 1. A lifting device 4 is mounted on the workbench, with a load-pressing driver 5 and a load pressure head 6 connected to the load-pressing driver 5 at one end of the lifting device 4. A microphone 7 is mounted at the middle of the bottom of the lifting device 4, and a clamping assembly 8 is mounted at the other end of the bottom of the lifting device 4. The toothbrush head drive mounting assembly 3 is used to insert a toothbrush head 9 from the toothbrush handle 2. When the toothbrush head 9 is inserted or removed, the load-pressing driver 5 is used to drive the load pressure head 6 to press down on the toothbrush head 9 to apply a set load pressure. The clamping component 8 is used to press the toothbrush handle 2 onto the carrier 1 to prevent the toothbrush handle 2 from lifting off the carrier 1 when the load pressure head 6 presses down on the toothbrush head 9, which would affect subsequent testing. The microphone 7 is used to pick up the vibration sound source generated when the toothbrush head 9 is inserted into the toothbrush handle 2 and the vibration sound source generated after the toothbrush head 9 is loaded to the set value, and transmit the sound source to the back-end test controller. This design uses the microphone 7 to replace the traditional manual inspection and judgment, which effectively improves the inspection quality.

[0021] In this embodiment, the clamping assembly 8 includes a top plate 81 and a bottom plate 82 located below the top plate 81. The top plate 81 is fixed to the other end of the bottom of the lifting device 4. A guide post 83 and a buffer spring 84 sleeved on the guide post 83 are provided between the two sides of the top plate 81 and the bottom plate 82. A clamping member 85 is provided at the lower end of the bottom plate 82. The bottom of the clamping member 85 is provided with an arc-shaped notch 851 adapted to the toothbrush handle 2. A support adapted to the toothbrush handle 2 is provided on the carrier 1. The toothbrush handle 2 is placed horizontally on the carrier 1 via two support brackets 11, and the clamping member 85 is located above the two support brackets 11 and above the lower part of the toothbrush handle 2. This design allows the entire clamping assembly 8 to be pressed down by the lifting device 4. The arc-shaped notch 851 of the clamping member 85 is engaged with the toothbrush handle 2 for clamping. The guide post 83 and the buffer spring 84 between the top plate 81 and the bottom plate 82 effectively buffer the clamping and pressing process, avoiding hard contact that could damage the product.

[0022] In this embodiment, a mounting housing 71 is provided at the bottom center of the lifting device 4. The microphone 7 is installed inside the mounting housing 71, and the head of the microphone 7 extends out of the mounting housing 71. The height of the head of the microphone 7 is higher than the height of the clamping member 85. The microphone 7 is located above the middle of the toothbrush handle 2. This design allows the microphone 7 to move closer to the middle of the toothbrush handle 2 under the drive of the lifting device 4 during the detection process, thus getting as close as possible to the vibration source of the toothbrush handle 2, effectively detecting and judging whether the toothbrush handle 2 vibrates to generate a sound source.

[0023] In this embodiment, the toothbrush head drive mounting assembly 3 includes a first transverse drive 31 and a transverse push plate 32 connected to the first transverse drive 31. The upper end of the first transverse drive 31 is provided with a first transverse guide rail 33 and a transverse carrier plate 34 adapted to be mounted on the first transverse guide rail 33. The end of the transverse carrier plate 34 is connected to the transverse push plate 32. The upper end of the transverse carrier plate 34 is provided with a second transverse guide rail 35, a cylinder mounting plate 36 adapted to be mounted on the second transverse guide rail 35, and a second transverse drive 37 connected to the cylinder mounting plate 36. The cylinder mounting plate 36 is provided with a toothbrush gripper cylinder 38 and symmetrically mounted on the toothbrush gripper cylinder 38. The toothbrush handle 2 has two gripper arms 39. When the two gripper arms 39 are combined, they form an inner cavity that fits the toothbrush head 9. One of the gripper arms 39 has a through-hole at its upper or lower end that extends into the inner cavity. An infrared sensor 310 is installed on the through-hole. The infrared sensor 310 is used to sense whether the toothbrush head 9 is being gripped. This design uses a first transverse drive 31 to initially move the entire toothbrush gripper cylinder 38 to the assembly position. Then, the second transverse drive 37 precisely inserts the toothbrush head 9 into the connector at the top of the toothbrush handle 2. At this time, a qualified toothbrush handle 2 will vibrate, and the sound source will be captured by the microphone 7. If the microphone 7 does not capture the sound source, it proves that the toothbrush handle 2 is defective.

[0024] In this embodiment, the drive end of the load-pressing driver 5 is connected to and fixed with a mounting block 51. A pressure sensor 52 is provided on the end wall of the mounting block 51. The load pressure head 6 is connected to the pressure sensor 52, and the load pressure head 6 is located directly above the toothbrush head 9 when it is inserted into the toothbrush handle 2. This design allows the load force to be set and feedback to be provided in real time by the pressure sensor 52. When the set load force is reached, the toothbrush handle 2 will vibrate three times, and the sound source generated will be captured by the microphone 7. If the microphone 7 does not capture the sound source, it proves that the toothbrush handle 2 is defective.

[0025] In this embodiment, the other end of the carrier 1 is provided with a base driver 10 and a toothbrush base seat 101 connected to the base driver 10. The base driver 10 is used to drive the toothbrush base seat 101 to extend out and be placed at the bottom of the toothbrush handle 2. This design can further ensure that the toothbrush handle 2 will not move laterally on the carrier 1.

[0026] In this embodiment, a wireless charger is provided inside the toothbrush base 101; this design can also keep the toothbrush handle 2 wirelessly charged during testing, and prevent the toothbrush handle 2 from not generating the corresponding vibration due to lack of power.

[0027] In this embodiment, the toothbrush handle 2 can be manually placed into the carrier 1, and then the test can be started. After the test, the toothbrush handle 2 can be removed. Alternatively, the carrier 1 with the toothbrush handle 2 placed in it can be transported to the test position by a conveyor belt. This can be achieved simply by adding a traditional position sensor and a corresponding blocking cylinder to the test position.

[0028] This invention relates to the technical field of electric toothbrush testing.

[0029] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
