（6）Schematic diagram of the robotic arm: (as shown in Figure 1 on the right)
- 1. According to the machining process requirements of the workpiece, the gantry loader in this project adopts a double-station orthogonal 90-degree swing gripper system, using standard pneumatic grippers to clamp parts, which meets the requirements of grabbing parts and changing materials inside the machine tool. The gripper is equipped with sensors for detecting the presence of workpieces and sensors for detecting the clamping and releasing status of the gripper. The gripper has the function of preventing workpieces from falling in case of air and power failure. The structural diagram of the robot gripper is as follows (whether the gripper is internally supporting or externally clamping shall be subject to the countersigned drawings).
（7）Storage method: double-layer tray stocking (as shown in Figure 2 on the right)
- The double-layer tray stocking adopts dual-drive and independent control, enabling pallet exchange for loading and unloading to ensure non-stop operation of the gantry loader. The tooling pallet and the main structure are designed as a separated structure for easy product changeover and loading/unloading. There are 4 pallets in total for the upper and lower layers, with each pallet measuring 250*500mm. Each pallet can store up to 40 workpieces, and the total storage capacity of the 4 pallets is 160 workpieces. The tooling pallet can be customized according to the customer's products, and this structure facilitates continued use when the customer replaces parts in the later stage (Note: The gripper also needs to be modified according to the external structure of the product).
