Abstract
Description
Technical Field
[0001] The invention relates to a crystal testing device. Background Art
[0002] The current quartz crystal performance test method is: after setting the frequency, resistance and other parameter ranges in the test machine software, the crystal to be tested is placed in the vibrating material tray. The crystals are automatically arranged one by one on the material tray track, with the leads facing upward and continuously entering the test track. The metal test probe set beside the track performs a pressure touch test on each passing crystal. The measured frequency, resistance and other electrical data are compared with the preset electrical parameters in the software, and qualified and unqualified products are automatically classified and placed. After qualified products are inspected and qualified, they are packaged and sent to customers for use;
[0003] Although the existing test machine measurement method can distinguish qualified and unqualified performance parameters such as frequency and resistance of crystals, there are some failure modes in the process of crystal resonators, such as defects in crystal materials, tiny cracks and breaks on the edges caused by wafer cutting and grinding, and the adhesion of conductive glue, which are recognized quality defects in the crystal industry. These defects are not easy to be found in the test. Even qualified products may have quality risks, which usually manifest themselves with the long-term operation of the components. The frequency may shift at the least, and the internal wafer may break or debond, causing the product to crash. In particular, our company's crystal products are mainly exported and used in automobiles, and their stability and safety are extremely important. Therefore, there is an urgent need for a testing device that can completely prevent the outflow of products with quality risks. Summary of the invention
[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a crystal testing device capable of eliminating inherent quality risks of products.
[0005] The technical solution adopted by the present invention is: the present invention includes a machine and a crystal loading module, and the machine is provided with a crystal transport module, a unloading module, a crystal electrical testing module and a crystal knocking module, the crystal loading module is connected to the crystal transport module, the unloading module is connected to one side of the crystal transport module, a crystal testing station is arranged on one side of the crystal transport module, the crystal electrical testing module and the crystal knocking module are both coordinated with the crystal testing station, and the crystal knocking module is located below the crystal electrical testing module.
[0006] Furthermore, the crystal loading module includes a vibration plate, a lifting module and a crystal sensor. The lifting module and the crystal sensor are both located at the end of the vibration plate and on one side of the crystal transport module. The vibration plate and the crystal transport module are both coordinated with the lifting module.
[0007] Furthermore, the crystal transport module comprises a belt-driven circulating transport module, and a plurality of crystal carriers are arranged on the belt-driven circulating transport module.
[0008] Furthermore, the crystal electrical property test module is cooperatively arranged above the crystal test station, and the crystal knocking module is cooperatively arranged below the crystal test station.
[0009] Furthermore, the crystal knocking module includes a knocking support seat, a knocking motor and a knocking head, the knocking motor is arranged on the knocking support seat, the knocking head is arranged on the knocking motor, and the knocking head is arranged below the crystal testing station.

[0011] The beneficial effect of the present invention is: compared with the conventional technology, there is a situation where it is impossible to prevent the outflow of products with quality hazards. In the present invention, when the crystal is transported to the crystal testing station, the crystal electrical testing module tests the crystal, and at the same time, the crystal knocking module knocks the crystal. The crystal knocking module continuously hits the outer shell surface of the crystal five times with a force of 1KG. At this time, the crystal with inherent defects will aggravate the expansion of the chip cracks until it breaks, and the conductive adhesive will be detached at the weakly bonded parts, which is enough to cause the crystal to fail to oscillate or the abnormal frequency resistance changes are measured, thereby achieving the purpose of eliminating products with inherent quality hazards. Therefore, the present invention has the advantage of being able to eliminate the inherent quality hazards of the product. BRIEF DESCRIPTION OF THE DRAWINGS
