The invention relates to the technical field of laser micro-nano machining, and discloses a femtosecond laser glue-free film high-speed high-precision welding system and method. According to the system and method, through dynamic speed-precision balance regulation and control, multi-layer film interface gradient combination, welding surface quality self-adaptive optimization and multi-target cooperative control, the problems that in existing femtosecond glue-film-free welding, the speed and precision are difficult to consider at the same time, the bonding strength of a multi-layer film interface is low, and the welding surface quality is poor are solved. Through an innovative algorithm and system design, collaborative improvement of high-speed welding and high precision is achieved, the interface bonding strength of multiple layers of thin films is enhanced, the flatness and smoothness of the welding surface are improved, and a new technical scheme is provided for high-speed, high-precision and high-quality glue-free thin film welding.

A method of manufacturing a base body of a weighing sensor of a high-precision balance in which a base body is machined out of a monolithic metal block and has at least one arm which is hinged to the rest of the metal block via integral bending spring joints in the form of thin spots. The base body is then acted upon with a chemical solution at least at the bending spring joints to cause a material removal at these points. Furthermore, a base body manufactured by this method is presented.

This invention relates to the field of rubber production and discloses a batching device for rubber production, including a precision balance and a platform scale. The precision balance has a sliding component inside, and a series of quantitative feeding scoops are placed inside the sliding component. These quantitative feeding scoops are designed for single-use feeding of different small doses of materials, ensuring precise feeding of varying amounts. A limit baffle is bolted to the top of the precision balance to regulate the operator's feeding actions and prevent material spillage due to arm movement. This invention has the following advantages and effects: by optimizing weighing equipment, improving operating methods, and adding auxiliary devices, it solves the problem of uncontrolled batching accuracy caused by manual operation and material characteristics in existing technologies, thereby significantly improving batching accuracy, stabilizing the quality of finished rubber products, increasing product qualification rate, and reducing production costs.
