Description

Technical Field

[0001] The utility model relates to the technical field of weighing equipment, in particular to a variable-position weighing workbench. Background Art

[0002] The weighing table is an important instrument for weighing. In traditional weighing, the weighing objects are randomly placed on the ground or on the tray of the electronic scale for weighing. In this way, only one item can be weighed at a time. If multiple objects are weighed, a large number of people or multiple weighing tables are required, which not only affects the quality of the product, but also requires a large amount of manpower and time, with low efficiency, which greatly increases a lot of labor costs.

[0003] There are usually work tables or workbenches in laboratories and production lines. After the operator completes the experiment, production or maintenance operations on the workbench, the product needs to be tested. The materials required for some products must be very precise. A little more or less will directly lead to test failure and product scrapping. In assembly line production, some products need to be tested for weight before leaving the factory to determine whether they meet the processing requirements. Conventional continuous weighing methods are difficult to meet the requirements of production line testing.

[0004] Variable-position weighing workbenches are now available on the market, which greatly improve work efficiency. However, they have complex structures, unreasonable designs, complicated operations, inconvenient maintenance, and high operating costs.

[0005] Therefore, engineers and technicians in this field are required to develop a weighing workbench suitable for laboratories and production lines to meet the needs of current experiments and production. Utility Model Content
