[0002] TO packaging is one of the most common detector packaging forms. Its structure generally includes a tube cap and a spherical lens arranged on the tube cap. This structure is usually made of optical glass sealed with a metal tube cap through a high-temperature sintering process; because During the subsequent packaging process, the cap is subject to relatively large vibrations. If the sealing strength is not enough, the problem of lens falling off will easily occur, which will affect product quality. In addition, in order to ensure product performance, the industry also has corresponding requirements for the sealing strength of the lens and cap and specifications;
[0003] In the prior art, there is no special equipment for testing the sealing strength of the lens and the cap, and the DAGE4000 (chip push-pull shear force tester) is generally used for testing; although the DAGE4000 is powerful, its structure is complex and the volume is large , the requirements for the operator are high, and the equipment is expensive. If it is dedicated to the lens and cap seal strength test, the cost performance is not high. In addition, the test period of the lens and cap seal strength test using DAGE4000 is longer , Low efficiency, only suitable for random inspection of products, not suitable for real-time detection during online production
