[0037] The working principle of this utility model:

[0038] The utility model adopts a positioning knife 7 and a cylinder to jointly limit and clamp the raw materials of the heat exchanger. The robot arm clamp grabs the raw materials and places them in the specified position (the clamp is other components of the same equipment where this mechanism is located). When positioning the manifold, the vertical cylinder 603 moves to drive the positioning knife 7 to insert and position the manifold, and the long rod cylinder 604 pushes forward to clamp and position the manifold in the front and back directions. The clamping cylinder 601 and the horizontal cylinder 602 simultaneously push the manifold and are clamped by the clamping block 6. The positioning knife 7 is connected to the vertical cylinder 603 to first perform an upward movement and then a horizontal movement as a clamp to grab and avoid, and then the robot arm side plate is used to grab. The order of the cylinder clamp's work is controlled through the interaction of electrical signals, so that the cylinder is delayed in retracting when the gripper grabs it, and the gripper sends the side plate to the next step of the program.

[0039] When positioning the side plate, the robot arm grips the raw material and places it in the specified position. The fixed block 4 fixes the side plate in the up and down direction, and the fixed cylinder 605 pushes one side of the top side plate to complete the clamping of the side plate. The robot arm then performs the grasping action. Through the interaction of electrical signals, the working sequence of the cylinder gripper is controlled, so that the cylinder delays the retraction of the gripper when the gripper grabs it and sends the side plate to the next step.

[0040] The utility model realizes the function of clamping and positioning raw materials by grabbing them through the robot arm, which solves the problem of inaccurate and time-consuming positioning of raw materials, saves the process of manual positioning and stacking, saves manpower and time, greatly improves efficiency, and improves positioning accuracy, thereby significantly reducing the scrap rate.

All equivalent changes and improvements made within the scope of application of the present invention shall still fall within the scope of the patent coverage of the present invention.
