[0021] 11 multiple grippers 12 piston recognition module DETAILED DESCRIPTION

[0022] The following describes the specific implementation of the embodiment of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the embodiment of the present invention and is not used to limit the embodiment of the present invention.

[0023] Example 1

[0024] Figure 1 The figure is a schematic diagram of the structure of an engine piston installation system according to a first embodiment of the present invention. The engine piston installation system 1 comprises a robot 10; a plurality of grippers 11; and a piston recognition module 12 for identifying the model information of the engine piston and transmitting the model information to the robot 10. Based on the received engine piston model information, the robot 10 selects a gripper from the plurality of grippers 11 that matches the engine piston model information and uses the selected gripper to install the engine piston.

[0025] Specifically, the piston recognition module 12 can identify the model information of the engine piston (e.g., piston number, size, etc.), and then transmit this information to the robot used to install the piston. After receiving the engine piston model information, the robot selects a gripper from multiple grippers that matches the piston and performs the installation operation. After installation is complete, the robot releases the gripper and returns to its initial position to await the next operation. If the piston model of the next engine to be installed is different from that of the previous engine, the robot replaces the gripper with another matching one for installation. The entire process can be performed continuously to improve production efficiency.

[0026] This embodiment of the present invention utilizes a piston recognition module to automatically identify the model information of an engine piston and transmit it to a robot used to install the engine piston. Upon receiving the model information, the robot selects a gripper from multiple grippers that matches the model information to install the piston. This embodiment of the present invention significantly reduces the possibility of incorrect engine piston installation and improves installation accuracy and efficiency.

[0027] Furthermore, the piston recognition module includes: a camera (not shown in the figure), which is used to obtain image information of the engine and identify model information of the engine piston based on the image information.

[0028] Specifically, different models of engines correspond to different models of engine pistons. The embodiment of the present invention utilizes a camera of a piston recognition module to obtain image information of the engine, and identifies the model information of the engine piston based on the image information of the engine.

[0029] The piston in the embodiment of the present invention can be either an assembled finished piston or an unassembled component corresponding to the piston model (i.e., after determining the piston model, the corresponding piston components such as the oil ring, gas ring, connecting rod and piston pin can be determined).

[0030] There are as many as thirty-six types of engine pistons. The camera of the piston recognition module can be used to obtain image information of the engine, and the model information of the engine piston can be identified based on the image information (for example, for piston assemblies that have not been assembled into finished pistons, the piston model information may include odd piston part numbers, even piston part numbers, piston first ring part numbers, piston second ring part numbers, and piston oil ring part numbers). The robot needs to match the grippers currently installed on the robot with the model information of the engine piston to be installed to determine whether the current robot grippers need to be replaced.

[0031] Furthermore, the clamping claw includes: a clamping portion and a driving portion (not shown in the figure), and the driving portion is used to drive the clamping portion to clamp the engine piston.

[0032] Furthermore, the robot is further configured to adjust the position and angle of the clamping portion and the driving portion based on the received model information of the engine piston. The robot adjusts the position and angle of the clamping portion and the driving portion based on the received model information to accommodate the installation requirements of engine pistons of different models while ensuring that the clamping jaws can accurately and stably clamp the piston.

[0033] Example 2

[0034] To ensure the accuracy and stability of the system, the second embodiment of the present invention further adds a calibration module (not shown in the figure) on the basis of the first embodiment, for calibrating the position and angle of the clamping part and the driving part.

[0035] The installation system 1 further includes a calibration module for calibrating the position and angle of the clamping portion and the driving portion.

[0036] A second embodiment of the present invention provides a calibration module to periodically calibrate the position and angle of the gripper to ensure system accuracy and stability. Specifically, this can be achieved by comparing the gripper with a standard reference and adjusting the gripper. Calibration can be performed periodically or when errors are detected.

[0037] Example 3

[0038] To further improve installation accuracy, this embodiment of the present invention adds a photoelectric sensor module (not shown) based on the first embodiment. The installation system 1 also includes a photoelectric sensor module for determining whether the gripper has gripped the engine piston and sending the judgment result to the robot.

[0039] During this process, the photoelectric sensor module is used to detect whether the gripper has successfully grasped the piston. If the gripper fails to detect the piston, a signal is sent to the robot for appropriate processing, such as re-grasping, to ensure the piston is successfully installed on the engine.

[0040] Example 4

[0041] Figure 2 4 is a flow chart of a method for installing an engine piston according to a fourth embodiment of the present invention. The method comprises the following steps S41-S42.

[0042] S41. Identify the model information of the engine piston using a piston identification module, and send the model information of the engine piston to the robot.

[0043] Furthermore, the identifying the model information of the engine piston by using the piston identification module includes: acquiring image information of the engine by using the piston identification module; and identifying the model information of the engine piston by using the image information of the engine.

[0044] Specifically, the piston in the embodiment of the present invention can be either an assembled finished piston or an unassembled component corresponding to the piston model (i.e., after determining the piston model, the corresponding piston components such as oil ring, gas ring, connecting rod and piston pin can be determined).

[0045] There are as many as thirty-six types of engine pistons. The camera of the piston recognition module can be used to obtain image information of the engine, and the model information of the engine piston can be identified based on the image information (for example, for piston assemblies that have not been assembled into finished pistons, the piston model information may include odd piston part numbers, even piston part numbers, piston first ring part numbers, piston second ring part numbers, and piston oil ring part numbers). The robot needs to match the grippers currently installed on the robot with the model information of the engine piston to be installed to determine whether the current robot grippers need to be replaced.

[0046] S42: Using the model information of the engine piston received by the robot, select a gripper that matches the model information of the engine piston from a plurality of grippers, and use the selected gripper to install the engine piston.

[0047] This embodiment of the present invention uses a piston recognition module to automatically identify the model information of an engine piston and transmit it to a robot used to install the engine piston. The robot then uses the received engine piston model information to select a gripper from multiple grippers that matches the model information for installation. This embodiment of the present invention significantly reduces the possibility of incorrect engine piston installation and improves installation accuracy and efficiency.

[0048] Furthermore, the robot is further configured to adjust the position and angle of the selected clamping jaws using the received model information of the engine piston. The robot adjusts the position and angle of the clamping jaws using the received model information to accommodate the installation requirements of engine pistons of different models while ensuring that the clamping jaws can accurately and stably clamp the piston.

[0049] Furthermore, the installation method further includes calibrating the position and angle of the clamping jaws by comparing the position and angle with a standard reference and adjusting the clamping jaws. Calibration can be performed regularly or when errors are found to ensure accuracy and stability of the installation process.
