Problems solved by technology

At present, the trimming is to manually use scissors to trim a single product along the outer frame of the product. This method not only has low production efficiency and high labor intensity, but also has low trimming dimensional accuracy, and there are large fluctuations in the dimensions of the same batch of products. , which is not conducive to the stable control of product quality; the measurement of resistance and voltage of strain gauges is completely dependent on manual testing. Due to the large output of strain gauges, many workers are required, resulting in high labor intensity, high production costs, low test efficiency, and error-prone , It is also not conducive to the stability control of product quality; moreover, sorting is also manual sorting. The manual sorting method not only has low production efficiency, high labor intensity, high production cost, and is prone to errors, it is also not conducive to product quality. stability control
