DETAILED DESCRIPTION
[0031] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0032] The utility model will be described in detail with reference to the drawings for further understanding the contents of the utility model.
[0033] Reference Figure 1 and Figure 4 This utility model discloses an intelligent workpiece assembly device, comprising a workbench 1, a support column 3 fixedly connected to the top left of the workbench 1, an alarm 5 fixedly connected to the top of the support column 3, an operation panel 2 fixedly connected to the front right of the top of the workbench 1, and a robotic arm 8 fixedly connected to the rear middle of the top of the workbench 1. Based on visual inspection and sensor detection results, the HSR-CR605 robotic arm 8 begins to move under the command of the central control system. This robotic arm has a collision detection function; when it encounters external facilities (subject to external force) during movement, it can quickly detect and immediately stop moving, greatly enhancing the safety of the robotic arm in complex working environments. In high-speed mode, it can quickly complete actions such as grasping and placing, improving assembly efficiency. In collaborative mode, the robotic arm 8 is more intelligent and safer, enabling better collaboration and interaction with surrounding equipment and operators. When manual intervention is required in certain assembly stages, the collaborative mode ensures safe interaction between the robotic arm 8 and the operator. The robotic arm 8 is equipped with a dual-station gripper capable of gripping bearings, couplings, and pallets of different specifications. After receiving instructions from the central control system, the robotic arm 8 will select the appropriate fixture according to the specific situation of the workpiece and accurately clamp the workpiece. If the workpiece needs to be prepared for assembly, the robotic arm 8 will clamp it to the raw material module; if the workpiece is ready for assembly, it will be placed in the assembly module. The support frame between the cylinders can be disassembled and replaced according to different workpieces. The support frame 4 is fixedly connected to the rear end of the right side of the top of the worktable 1.
[0034] Reference Figure 2 A detection component is installed at the top right center of the workbench 1. The detection component includes a fixed rod 9, which is fixedly connected to the top right center of the workbench 1. A mounting bracket 16 is fixedly connected to the outer ring of the fixed rod 9. A camera 17 is fixedly connected to the top left outer wall of the fixed rod 9. A light 18 is fixedly connected to the bottom left side of the mounting bracket 16. A camera 19 is fixedly connected to the bottom front end of the mounting bracket 16. When the tray is in place, sensor detection is performed first. The sensor performs preliminary physical characteristic detection on the tray and the workpiece on it, detecting the presence of workpieces, their approximate positions, and other information. Then, the vision scanning module starts working. It consists of hardware such as the intelligent camera 17, the light 18, and the camera 19. Through the coordinated action of these hardware components, the color of the workpiece is recognized and its position is determined. At the same time, the type of workpiece and its precise position and size information are determined. The results of these detections and recognitions are transmitted to the unit control system and subsequent execution equipment.
[0035] Reference Figure 3A conveyor belt 10 is fixedly connected to the top of the support frame 4. A tray mechanism 11 is set at the bottom front end of the conveyor belt 10. The original workpiece 14 is set at the front left side of the top of the worktable 1, and the workpiece to be assembled 15 is set at the front right side of the top of the worktable 1. A fixed frame 6 is fixedly connected to the middle left side of the top of the worktable 1, and an assembly mechanism 7 is set on the top of the fixed frame 6. In the assembly mechanism 7, the operation of pressing the bearing into the coupling using a cylinder is the core assembly step. During this process, the pressure value is analyzed in real time and the movement position of related components is monitored through a pressure detection device to determine whether the assembly is qualified. If the pressure value is within the preset qualified range and the movement position meets the assembly requirements, the assembly is successful; otherwise, if the pressure value is abnormal or the movement position deviation is large, the assembly is unqualified and needs to be adjusted or reassembled. The assembled workpiece is still inspected in the assembly module. The inspection content may include the overall dimensional accuracy after assembly, the firmness of the connection, etc. The inspection results are also fed back to the central control system. If the workpiece passes the inspection, the robotic arm 8 will place it in the raw material module for further processing or return it to the pallet according to the instructions of the central control system, so as to transport it back to the intelligent warehousing station. If the inspection fails, it may be placed in a specific non-conforming product area or reassembled. An RFID reader 12 is set at the bottom of the rear end of the conveyor belt 10. The RFID reader 12 can read the information on the pallet to determine the preliminary condition of the material. The blocking mechanism is used to restrict the movement of the pallet at a specific time to ensure the accuracy and stability of the operation. The pallet temporary storage position provides temporary storage space for the pallet for subsequent processing. A blocking mechanism 13 is set at the bottom of the middle of the conveyor belt 10.
[0036] Working principle: When the equipment is started, the conveyor belt 10 on the top of the support frame starts to operate. The tray mechanism 11 on the conveyor belt 10 is used to carry the workpiece for transmission. The RFID reader 12 at the bottom of the rear end of the conveyor belt 11 can identify and read information of the passing workpiece. The blocking mechanism 13 at the bottom of the middle of the conveyor belt 11 can block the movement of the workpiece when necessary to facilitate subsequent operations. The camera 17 in the detection component collects images of the workpiece on the workbench 1 to obtain information such as the position and shape of the workpiece. The light 18 at the bottom left of the mounting frame 16 can provide illumination for the camera 17 to take pictures. The camera 19 at the bottom front end can also assist in obtaining relevant information of the workpiece. According to the information fed back by the detection component, the robotic arm 8, with the cooperation of the assembly mechanism 7 at the top of the fixed frame 6, accurately grabs the workpiece to be assembled and assembles it onto the original workpiece 14. If any abnormal situation occurs during the assembly process, such as excessive deviation of the workpiece position or unsmooth assembly, the alarm 5 at the top of the support column 3 will sound an alarm to prompt the operator to handle it. The whole process achieves intelligent, efficient and accurate workpiece assembly operation through the coordinated work of various components.
