Description

Technical Field

[0001] This application relates to the field of engine housing assembly technology, and in particular to an engine housing laser engraving system. Background Technology

[0002] During the assembly of engine housings, one step involves engraving the housing to identify parameters such as the model number. Current laser engraving processes for engine housings still rely on manual or semi-automated methods for loading / unloading, positioning, engraving, and quality inspection, resulting in low production efficiency and difficulty in ensuring consistency. For example, traditional production lines require operators to manually move the housing to the turntable assembly fixture, adjust its position, and clamp it. A single loading / unloading operation can take 3-5 minutes, and manual intervention easily introduces positioning errors. Furthermore, quality inspection after engraving is usually performed offline, which not only extends the production cycle but also makes it difficult to comprehensively control quality risks due to insufficient sampling rates.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0018] During the assembly of engine housings, one step involves engraving the housing to identify parameters such as the model number. Current laser engraving processes for engine housings still rely on manual or semi-automated methods for loading / unloading, positioning, engraving, and quality inspection, resulting in low production efficiency and difficulty in ensuring consistency. For example, traditional production lines require operators to manually move the housing to the turntable assembly fixture, adjust its position, and clamp it. A single loading / unloading operation can take 3-5 minutes, and manual intervention easily introduces positioning errors. Furthermore, quality inspection after engraving is usually performed offline, which not only extends the production cycle but also makes it difficult to comprehensively control quality risks due to insufficient sampling rates.

[0019] Based on this, an exemplary embodiment of this application provides an engine housing laser engraving system. The system includes a loading / unloading robot, an engraving robot, and a turntable assembly. The loading / unloading robot is positioned on one side of the conveyor line; the engraving robot and the turntable assembly are positioned on the other side of the conveyor line. The turntable assembly is mounted on a frame, and the engraving robot is positioned on one side of the frame. The engraving robot is equipped with a laser engraving unit and a vision inspection unit. Through the coordinated operation of the loading / unloading robot and the conveyor line, automatic loading and unloading of the engine housing is achieved, reducing manual intervention, shortening the loading / unloading time per cycle, and improving loading / unloading efficiency. The vision inspection unit provides real-time positioning of the engraving position on the engine housing, improving engraving position accuracy. Simultaneously, quality inspection is performed immediately after engraving to identify key indicators such as the clarity of the engraved text and characters, improving inspection efficiency.

[0020] An exemplary embodiment of this application provides a laser engraving system for an engine housing, such as... Figure 1 and 2 As shown, the engine housing laser engraving system includes a loading / unloading robot 10, an engraving robot 20, and a turntable assembly 30. A material tray can be carried on the conveyor line 60, and the material tray can move along the conveyor line to each process. The material tray carries the engine housing. When the material tray moves to the laser engraving station, it is lifted by a lifting mechanism. The loading / unloading robot 10 is located on one side of the conveyor line 60. The loading / unloading robot 10 can load and unload the engine housing between the material tray and the turntable assembly 30 on the conveyor line 60. Thus, through the coordinated operation of the loading / unloading robot 10 and the conveyor line 60, automatic loading and unloading of the engine housing is achieved, reducing manual intervention, shortening the loading / unloading time per cycle, and improving loading / unloading efficiency.

[0021] The engraving robot 20 and the turntable assembly 30 are located on the other side of the conveyor line 60; the turntable assembly 30 is mounted on the frame 40, and the engraving robot 20 is located on one side of the frame 40; preferably, the engraving robot 20 is a six-axis robot, and a laser engraving unit 201 and a vision inspection unit 202 are provided at the end of the engraving robot 20; the laser engraving unit 201 is used for engraving the engine block model; the vision inspection unit 202 is used to detect and locate the engraving position on the engine block, and to detect the engraving quality after the engraving is completed. Thus, the engraving system of this application can locate the engraving position on the engine block in real time through the vision inspection unit 202, thereby improving the engraving position accuracy; at the same time, it can immediately perform quality inspection after the engraving is completed, identify key indicators such as the clarity of the engraved text and characters, and improve the efficiency of inspection.

[0022] Preferably, the vision inspection unit 202 includes a 3D camera and a 2D camera; the 3D camera is used to detect and locate the engraving position on the engine compartment; the 2D camera is used to detect the engraving quality after the engraving is completed.

[0023] like Figures 3 to 6 As shown, the turntable assembly 30 includes a rotary drive unit 301, a reducer 302, a cam divider 303, and a housing support turntable 304. The rotary drive unit 301 is mounted on the frame 40, and the rotary drive unit 301, reducer 302, cam divider 303, and housing support turntable 304 are sequentially connected. Preferably, the rotary drive unit 301 is a motor, so that the rotary drive unit 301 can drive the housing support turntable 304 to rotate. When the engine housing is supported on the housing support turntable 304, the engine housing also rotates synchronously with the housing support turntable 304.

[0024] For example, the housing carrier turntable 304 includes a chassis 3041, a carrier component 3042, and a positioning unit 3043; the carrier component 3042 is disposed on the chassis 3041, and the positioning unit 3043 is disposed on the carrier component 3042. There can be multiple carrier components 3042. Preferably, the carrier component 3042 includes a first carrier component 3042a, a second carrier component 3042b, and a third carrier component 3042c, with a loading / unloading channel 305 formed between each pair of carrier components 3042. During loading, the grippers of the loading / unloading robot 10 can be inserted into the loading / unloading channel 305 to place the engine housing on the carrier component 3042, achieving loading and positioning of the engine housing; after the engine housing is engraved, the grippers of the loading / unloading robot 10 can be inserted into the loading / unloading channel 305 to hold the engine housing and transfer it to the material tray of the conveyor line.

[0025] Preferably, to facilitate loading and unloading by the loading / unloading robot 10, during loading and unloading of the engine housing, the rotary drive unit 301 drives the housing-supporting turntable 304 to rotate, making the loading / unloading channel 305 perpendicular to the movement direction of the conveyor line 60. This facilitates loading and unloading by the loading / unloading robot 10 while ensuring that the engine housing is precisely positioned on the housing-supporting turntable 304 during loading. During this process, the rotary drive unit 301 and the cam divider 303 enable the housing-supporting turntable 304 to be precisely positioned at a preset angle.

[0026] To accommodate engine housings of different sizes and achieve positioning for them, multiple positioning units 3043 are provided, spaced apart on the support assembly 3042. For example, each positioning unit 3043 may be a positioning pin or a positioning tube. The positioning pin may extend beyond the end face of the support assembly 3042; the positioning tube may be a hollow tube with its upper end face lower than the upper end face of the support assembly 3042. When a positioning pin is provided on the engine housing, it can be inserted into the positioning tube to achieve positioning of the engine housing. When a positioning hole is provided on the engine housing, it can be fitted with a positioning pin on the support assembly 3042 to achieve positioning of the engine housing.

[0027] Preferred, such as Figure 2 As shown, the engraving system also includes a dust extraction unit 50. The suction port of the dust extraction unit 50 is located above the turntable. The dust extraction unit 50 is used to extract and filter the fumes generated during the engraving process. The filtered clean gas is discharged from the dust extraction unit 50. In this way, metal fumes and particulate matter can be captured in real time during the laser engraving process, preventing harmful substances from spreading to the workshop environment. At the same time, it can ensure that there is no accumulation of fumes in the engraving area and improve the clarity of the engraving.

[0028] The working process of the engine housing laser engraving system of this application is as follows: First, the rotary drive unit 301 drives the housing support turntable 304 to rotate, so that the loading and unloading channel 305 is perpendicular to the movement direction of the conveyor line 60; second, the loading and unloading robot 10 clamps the engine housing and loads the engine housing onto the housing support turntable 304; then, the engraving robot 20 drives the 3D camera above the engine housing to take pictures of the engine housing in order to identify the position on the engine housing that needs to be engraved; the engraving robot 20 drives the laser engraving unit 201 to move to the position on the engine housing that needs to be engraved and engraves the engine housing; after the engraving is completed, the engraving robot 20 drives the 2D camera to take pictures of the engraved mark in order to detect the engraving quality after the engraving is completed.
