Specifically, the present invention as a whole uses a connecting seat and a support as a connecting support carrier. The connecting seat is connected to the driving mechanism above, and is driven by the driving mechanism to move back and forth between different workstations, and move up and down in the vertical direction to pick up and put materials; the support is located below the connecting seat, and a plurality of material picking positions are arranged at intervals at its bottom, and an adjustment component is arranged correspondingly at each material picking position, and a longitudinal clamping component is arranged correspondingly below each adjustment component; at the same time, a group of transverse clamping components are also arranged below the support, and the group of transverse clamping components respectively extend to the front and rear (lateral direction) sides of the plurality of material picking positions.

After being tightly fixed and corrected for flatness, the core body is clamped and fixed in the longitudinal and transverse directions by the longitudinal clamping cylinder and the transverse clamping cylinder respectively, and then taken out; further, when the pressing block of the pressing and calibration assembly of the present invention presses the core body, the vertically arranged pressing and calibration spring is used to provide elastic buffering in the vertical direction, so as to reduce the damage to the surface of the core body during the pressing and calibration; when the pressing block is moved upward by the upward reaction force of the core body, it approaches the pressure sensor above, thereby realizing real-time and accurate monitoring of the pressing and calibration force, and through pressure feedback information, the pressing and calibration distance can be controlled in real time during the pressing and calibration process. In addition, during the pressure calibration process, the pressure block of the present invention is supported by a vertically arranged pressure rod, and the pressure rod is slidably inserted in the pressure calibration sleeve. In order to prevent the pressure rod from falling downward out of the pressure calibration sleeve due to its own gravity, a step portion arranged at the bottom of the pressure calibration sleeve and a pressure cap portion arranged at the top of the pressure rod are used to block and limit the pressure. A pressure calibration spring is vertically inserted at the top of the pressure rod, and the top of the pressure calibration spring is limited by a spring limiting column horizontally arranged on the pressure calibration support plate to provide a downward supporting force. When the pressure block is subjected to an upward force, the pressure rod is driven to compress the pressure calibration spring upward. After being compressed, the pressure calibration spring provides a downward elastic force to achieve elastic buffering of the pressure block. BRIEF DESCRIPTION OF THE DRAWINGS
