Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of ultrasonic handles, and in particular to a waterproof packaging process for ultrasonic handles. Background Art
[0002] Ultrasonic teeth cleaning technology and dental ultrasonic bone knife machines have been widely used in the field of oral medical health. Ultrasonic teeth cleaning machines can effectively remove supragingival and subgingival calculus, and dental ultrasonic bone knife machines can quickly perform dental surgeries such as alveolar bone incision. These handles need to be ultrasonically cleaned and sterilized with high-temperature steam.
[0003] Currently, the handles either fail due to structural and technical problems that make the ceramic pieces susceptible to water ingress, or are designed to be very complex for waterproofing, increasing the difficulty and cost of processing and assembling the handles. Summary of the Invention
[0004] The object of the present invention is to provide a waterproof packaging process for an ultrasonic handle, aiming to solve the problem of poor waterproof effect of the existing ultrasonic handle packaging process.
[0005] To achieve the above object, the present invention provides a waterproof packaging process for an ultrasonic handle, comprising the following steps:
[0006] Connect the transducer to the connector through the silicone water tube and the transducer wire;
[0007] A preset amount of encapsulation material is injected and solidified to fill the gap between the outside of the ceramic sheet and the inner wall of the handle shell, thereby sealing the ceramic sheet and waterproofing the solder joints of the connector and the wire.
[0008] After injecting glue, the handle is placed on the tooling within the preset time, placed in a sealed container, and the container is vacuumed by an air pump;
[0009] The ultrasonic handle after vacuum treatment is left to stand until the packaging material is completely solidified.
[0010] Among them, in "injecting a preset amount of packaging material and curing it to fill the gap between the outside of the ceramic sheet and the inner wall of the handle shell, sealing the ceramic sheet and waterproofing the welding points of the connector and the wire", the packaging material is silicone or other potting glue.
[0011] Among them, in "injecting a preset amount of packaging material and curing it to fill the gap between the outside of the ceramic sheet and the inner wall of the handle shell, sealing the ceramic sheet and waterproofing the welding points of the connector and the wire", the Shore hardness after curing is 30A-60A degrees.
[0012] Among them, in "after injecting glue, stand the handle on the tooling within the preset time, put it in a sealed container, and use an air pump to vacuum the container for the preset time", the preset time is 1 hour, and the preset time for vacuum treatment is 1-10 minutes.
[0013] Among them, in the process of "after injecting glue, standing the handle on the tooling within a preset time, placing it in a sealed container, and vacuuming the container with an air pump", the relative vacuum degree is 0.1-1 bar.
[0014] The present invention provides a waterproof packaging process for an ultrasonic handle, comprising the following steps: connecting the transducer and the connector via a silicone water tube and a transducer wire; injecting a preset amount of packaging material, curing the material, and then filling the gap between the outside of the ceramic sheet and the inner wall of the handle housing to seal and waterproof the ceramic sheet, while also sealing and waterproofing the welding points of the connector and the wire; after injecting the glue, placing the handle on a tool within a preset time, placing it in a sealed container, and evacuating the container with an air pump; and allowing the vacuum-treated ultrasonic handle to stand until the packaging material is completely cured. The present invention uses potting glue such as silicone to fully seal the ceramic sheet on the transducer, thereby optimizing the sealing and waterproofing effect and significantly extending the service life of the handle. This process simplifies the structure of the ultrasonic handle, makes production very simple, reduces costs, and improves the sealing performance of the glue, thereby enhancing the reliability of the handle and simplifying the operating process, thereby solving the problem of poor waterproofing in the existing ultrasonic handle packaging process.

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0017] Figure 2 This is a flow chart of a waterproof packaging process for an ultrasonic handle provided by the present invention.
[0018] In the figure: 10-handle housing, 20-transducer, 30-mounting base, 40-connector. DETAILED DESCRIPTION
[0019] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.
[0020] See also Figures 1 to 2 The present invention provides a waterproof packaging process for an ultrasonic handle, comprising the following steps:
[0021] S1 connects the transducer 20 to the connector 40 via a silicone water tube and a transducer 20 wire;
[0022] The packaging material is silica gel or other potting glue.
[0023] The Shore hardness after curing is 30A-60A.
[0024] Specifically, the transducer 20 and connector 40 are first connected via silicone tubing and transducer 20 wires to ensure a secure and airtight connection. The encapsulation material is silicone or other potting glue, with a Shore hardness of 30A-60A after curing. This hardness range ensures good sealing performance without affecting the handle's operational flexibility due to excessive hardness.
[0025] S2: injecting a preset amount of encapsulation material and curing it to fill the gap between the outside of the ceramic sheet and the inner wall of the handle housing 10, thereby sealing the ceramic sheet and the welding point of the connector 40 and the wire.
[0026] Specifically, a preset amount of packaging material is injected so that the cured glue can fully fill the gap between the outside of the ceramic sheet and the inner wall of the handle shell 10, thereby sealing and waterproofing the ceramic sheet and the welding points of the connector 40 and the wire.
[0027] After S3 injects glue, the handle is placed on the tooling within the preset time, placed in a sealed container, and the container is vacuumed by an air pump for the preset time;
[0028] The preset time is 1 hour.
[0029] The preset time for vacuum treatment is 1-10 minutes.
[0030] The relative vacuum degree is 0.1-1 bar.
[0031] Specifically, after injecting the glue, the handle should be placed on a workpiece within a preset time (e.g., within 1 hour) and placed in a sealed container. The container should then be evacuated using an air pump. The relative vacuum level should be controlled between 0.1 and 1 bar. This range effectively removes bubbles from the glue and improves its sealing properties. During the evacuation process, the handle and glue should be closely monitored to ensure that the glue can fully release the gas trapped within the vacuum environment.
[0032] S4 allows the ultrasonic handle after vacuum treatment to remain still until the packaging material is completely solidified.
[0033] Specifically, the vacuum-treated ultrasonic handle is left to stand, allowing the encapsulation material to fully cure under suitable environmental conditions. The curing process takes a certain amount of time, typically determined by the properties of the potting adhesive used and the process requirements. This ensures a good seal and waterproofing effect.
[0034] Example 1:
[0035] The connection between the transducer 20 and the connector 40 includes a silicone water tube and a transducer 20 wire. By injecting a certain amount of silicone or other potting glue, the Shore hardness after curing is between 30A-60A degrees, filling the gap between the outside of the ceramic piece and the inner wall of the handle shell 10, the ceramic piece is sealed and waterproof, and the welding points of the connector 40 and the wire are also sealed and waterproof, and then the mounting base 30 is installed into the handle shell.
[0036] After injecting the glue, within a certain period of time, such as within 1 hour, stand the handle on the tooling, place it in a sealed container, and use an air pump to vacuum the container to a relative vacuum degree of 0.1-1 bar. Let it stand for 1-10 minutes to allow the bubbles to be fully discharged.
[0037] After vacuuming, let it sit for a while to allow the glue to cure completely.
[0038] Example 2:
[0039] In this example, the gaps between the connector 40 and the handle housing 10, the mounting base 30 and the handle housing 10, and the handle housing 10 and the transducer 20 are sealed with silicone, and then the bubbles generated in the glue during the assembly process are removed by vacuuming.
[0040] The above disclosure is only a preferred embodiment of the waterproof packaging process of an ultrasonic handle of the present invention. Of course, it cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that implementing all or part of the processes of the above embodiment and making equivalent changes in accordance with the claims of the present invention still fall within the scope of the invention.
