This invention discloses a method, apparatus, equipment, and medium for dynamic management and control of key resource inventory and changes, relating to the field of automotive manufacturing technology. The method includes importing a current electronic spreadsheet of outsourced resource component inventory into an M-BOM system to obtain an outsourced resource component inventory table; setting up an interception operation for design changes in the verification process of process document processing, and marking the components corresponding to the intercepted design changes; and waiting for the marked component inventory to be depleted before re-establishing the marked component inventory. This application can effectively manage and control design changes to inventory components.

This utility model discloses a robot domain controller and robot hardware system based on a modular system. The robot domain controller includes a core computing module and a carrier board integrating the following functional circuits: a multi-rate Ethernet interface circuit, a wireless communication module interface, a storage device interface, an audio output interface with integrated power amplifier circuitry, an onboard inertial measurement unit (IMU), and a converged expansion interface. The converged expansion interface is used to connect to external expansion boards to provide robot-specific buses and signals. Adopting the above technical solution can improve integration, interface adaptability, product design level, and reduce costs.

The application relates to the technical field of semiconductor manufacturing, and particularly discloses a heating disc reference position adjusting method and adjusting device, which are used for aligning and adjusting the spatial position of a heating disc in an internal chamber of a film coating equipment. The adjusting method comprises the following steps: installing a level detector on the heating disc; adjusting the levelness of the heating disc under a vacuum environment, and confirming that the heating disc is in a horizontal posture through the level detector; adjusting the levelness of the heating disc under normal pressure, and confirming that the heating disc is in a horizontal posture through the level detector; aligning the heating disc under normal pressure, aligning the center of the heating disc with the center of the internal chamber of the film coating equipment, and determining the reference position of the heating disc. The combination of the level detector and the tool structure can realize horizontal adjustment and centering adjustment, and can greatly reduce the production cost of the wafer film coating equipment.

The invention provides a hard inclined rock surface cast-in-place pile drilling method, and relates to the technical field of constructional engineering. The hard inclined rock surface cast-in-place pile drilling method comprises the steps that the soft rock stratum position of a pile hole is determined; a first excess steel bar of a pile foundation reinforcement cage main bar is inserted into the soft rock stratum in the axial direction of a pile hole, and a first layer of rubble is backfilled; a percussion drill is used for pressing the first excess steel bars and the first layer of rubbles into the soft rock stratum; second excess material reinforcing steel bars of main reinforcements of the pile foundation reinforcing cage are made into reinforcing steel bar meshes, and the reinforcing steel bar meshes are horizontally filled into the pile holes; backfilling a second layer of rubble on the reinforcing mesh; impacting the second layer of rubbles by using the percussion drill; and drilling. And through combined backfilling of the horizontal reinforcing mesh and the second layer of rubbles, the uniformity of an impact interface can be improved, and deflection of a drilling tool of the impact drill is avoided, so that the drilling construction efficiency can be improved while the drilling cost of the hard inclined rock surface cast-in-place pile can be reduced.
