The utility model relates to the technical field of ink production, and concretely relates to ink adhesion dynamic testing device, including support component and setting uncoiling part, tension roller group, vertical grid part, horizontal grid part, ink stripping part, image acquisition part and winding part in proper order along the uncoiling direction, the upper portion of support component is equipped with the first support surface, and the first support surface provides the support for the roll material to be tested. The application adopts the step -by -step conveying of roll material and the horizontal movement of horizontal grid roller to work cooperatively, can complete high -precision grid drawing in the continuous production process simultaneously, avoids the test deviation caused by manual grid strength \ angle deviation, and simultaneously, the application can accurately control the adhesive tape attachment pressure and the peeling angle, ensures the standardization of peeling action, reduces the influence of human operation randomness on the result.

The utility model relates to the technical field of furniture surface paint film physical and chemical performance tests, in particular to a paint film impact resistance test grid drawing template which comprises a transverse drawing plate and a vertical drawing plate which are used in cooperation, a transverse line groove is formed in the transverse drawing plate, a vertical line groove is formed in the vertical drawing plate, and the transverse line groove is communicated with the vertical line groove. A plurality of transverse line grooves and a plurality of vertical line grooves are arranged at intervals, and the transverse line grooves and the vertical line grooves are mutually perpendicular when used in cooperation, a worker only needs to align the transverse marking plate and the vertical marking plate to the upper left corner of a test piece in sequence, and transverse lines and vertical lines which are perpendicular to each other are rapidly drawn through the transverse line grooves and the vertical line grooves; by means of the mode, the grid drawing process is greatly simplified, the grid drawing time is greatly shortened, the test efficiency is remarkably improved, meanwhile, due to the prefabricated transverse line grooves and the prefabricated vertical line grooves, it is ensured that the line positions are accurate, manual measurement errors are avoided, it is ensured that the drawn grids strictly meet the standard requirements, and the grid drawing accuracy is improved.

This application relates to the field of laser processing technology, and more particularly to a method, system, terminal device, and storage medium for detecting backlash. The backlash detection method includes: controlling a laser cutting machine to return to its mechanical origin, executing a specific scribing program and initiating a reverse grid drawing motion; using a vision system to identify and measure the grid lines; and combining image processing technology to calculate the mechanical backlash. This method eliminates the need for expensive third-party testing tools, is simple to operate, highly automated, and can quickly and accurately detect mechanical backlash. It adapts to the time-varying characteristics of backlash in the belt and synchronous gear transmission structures of laser cutting machines, meets the requirements for equipment error detection, reduces measurement costs, and eliminates human error. The system, terminal device, and storage medium provided in this application, being based on the backlash detection method, also possess the aforementioned technical effects.
