Description

Technical Field

[0002] As a smart wearable device that combines fashion and technology, smart watches have become an important part of modern life. With the continuous advancement of technology, the functions of smart watches are increasing. In addition to displaying time, they can also track sports, monitor health, and provide information reminders. Since they may be exposed to moisture in daily use, such as rain and splashing water when washing hands, the waterproof performance of smart watches has become one of the important indicators to measure their quality.

[0003] Usually, the watch body is placed on the top of the lower mold, and then the lower mold is pushed into the interior of the airtightness testing machine. Then, the upper mold inside the testing machine is used to press down to form a sealed chamber between the upper and lower molds, and then the watch body is tested for airtightness. However, if the lower mold is manually pushed into the interior of the testing machine, it is easy to cause the lower mold and the upper mold to be misaligned in the longitudinal direction, resulting in misalignment during the sealing process of the lower mold and the upper mold, thereby causing errors in the sealing. In addition, since there are many types of watch appearances, the lower mold needs to be replaced for different watch airtightness tests, and the method of fixing with screws is usually troublesome. For this reason, a smart watch airtightness testing machine is needed to solve the existing deficiencies. Utility Model Content
