[0043] A plurality of chip blowing racks, corresponding to the machine tools, located at the operating end of the corresponding machine tools, for placing processed parts;

[0044] A plurality of loading racks, corresponding to the chip blowing racks, located at one end of the corresponding chip blowing rack away from the machine tool, for placing the parts to be processed;

[0045] A plurality of unloading racks, corresponding to the chip blowing racks, are located at one end of the corresponding chip blowing racks away from the machine tool; used to place the parts after chip blowing; the plurality of unloading racks and the plurality of loading racks are located in the same assembly line direction;

[0046] A single industrial robot is located between the plurality of chip blowing racks and the plurality of unloading racks, and is used to carry parts between the plurality of machine tools and the plurality of loading racks, and / or to carry parts between the plurality of chip blowing racks and the plurality of loading racks;

[0047] The positioning sensor is arranged on the industrial robot and is used to detect the status of parts.

[0048] In the embodiment of the present invention, the parts processing system may include multiple machine tools, multiple chip blowing racks, multiple loading racks, multiple unloading racks, a single industrial robot and a positioning sensor. The number of machine tools can be determined according to actual conditions, and the embodiment of the present invention does not specifically limit this. For example, Figure 1 As shown, there can be three machine tools. The number of corresponding chip blowing racks, loading racks and unloading racks is the same as the number of machine tools. When there are three machine tools, there are three corresponding chip blowing racks, loading racks and unloading racks.

[0049] Machine tools can be set up in different types according to the needs of the process, including but not limited to lathes, milling machines, boring machines, drilling machines, laser cutting machines, etc. Lathe: Mainly used for processing various rotating surfaces and end faces of rotating bodies, and the cutting process is completed by rotating the workpiece and moving the tool. Lathes can process parts of different shapes such as inner holes, outer circles, end faces, threads, etc., and are widely used in the manufacturing industry. Milling machine: Used to process parts of different shapes such as planes, curved surfaces, drilling holes, grooves, and toothed parts. The milling machine rotates the spindle tool, the workpiece does the feed movement, and uses forces in different directions to complete cutting or non-cutting processing. Milling machines are widely used in mold processing, machinery manufacturing and other fields. Drilling machine: Mainly uses drill bits to process holes on the workpiece. Different drill bits can be used for cutting processing according to the size and shape of the processing object. Drilling machines are also usually used as a supplement to other machine tools to make the entire processing process more complete. Grinding machine: Used to process high-precision parts. The high-speed rotation of the spindle drives the grinding wheel to process, which can obtain finer surface finish and processing accuracy. Grinding machines play an important role in precision manufacturing and production with high quality requirements. Boring machines: Mainly used for machining high-precision holes or finishing multiple holes in one positioning. Boring machines have high machining accuracy and are suitable for occasions with strict requirements for hole machining. Laser cutting machines: Equipment that uses laser beams to cut or punch materials. It has the advantages of fast cutting speed and high cutting accuracy and is suitable for difficult-to-process materials such as metals. Secondly, the above-mentioned machine tools can be CNC machine tools.

[0050] A chip blower is a device used to remove and collect debris from the workpiece surface or processing area during machining. It combines the basic structure of the material rack with the chip blowing function, aiming to improve machining efficiency, keep the working environment clean, and reduce the potential damage of debris to the workpiece and equipment. The chip blower is located at the operating end of the corresponding machine tool, where parts processed by the machine tool can be placed, so as to remove and collect the chips of the processed parts. The chip blower mainly generates high-pressure airflow through a blowing device (such as a blowing nozzle, nozzle, etc.) to blow away debris, chips and other impurities on the workpiece surface or in the processing area, and centrally process them through a specific collection system (such as a collection box, vacuum cleaner, etc.). This process not only helps to keep the processing area clean, but also reduces the impact of debris on machining accuracy and equipment performance. The structure of the chip blower usually includes several main parts: Support frame: As the skeleton of the entire device, the support frame is responsible for carrying components such as the blowing device, the collection system and the workpiece. It is usually made of strong materials such as steel to ensure sufficient stability and load-bearing capacity. Blowing device: including blowing nozzles, nozzles and other components, which use high-pressure airflow to blow the debris away from the workpiece surface. The number and layout of the blowing devices are determined according to the specific processing requirements to ensure effective cleaning of every corner of the workpiece. Collection system: including collection boxes, vacuum cleaners and other components, used to collect the blown-away debris. The collection system is usually connected to the blowing device, and the debris is sucked in and centrally processed through negative pressure or gravity. The working principle of the chip blower is mainly based on the purging and collection of high-pressure airflow. During the processing, the high-pressure airflow generated by the blowing device blows away the debris on the surface of the workpiece or in the processing area, and is centrally processed through the collection system. At the same time, the control system accurately controls the operation of the blowing device and the collection system to ensure the optimization of the cleaning effect and equipment performance.

[0051] The loading rack is arranged at the end of the corresponding chip blowing rack away from the machine tool, and can be used to place the parts to be processed, so that when the parts to be processed are not entered into the machine tool for processing, they can be stored centrally for easy loading. The loading rack can be a fixed loading rack, which is installed on the side of the chip blowing rack away from the machine tool to transport the parts to be processed from the ground to a high place or from a high place to the ground.

[0052] The unloading rack can also be set at the end of the corresponding chip blowing rack away from the machine tool, and multiple unloading racks and multiple loading racks are located in the same assembly line direction, so that collaborative assembly line processing can be carried out based on the assembly line method, reducing the system footprint and improving production efficiency. The unloading rack can be used to place the parts after chip blowing, so that the parts after chip blowing can be stored centrally after the machine tool processing and the chip blowing of the chip blowing rack are completed, which is convenient for unloading and product outflow. The unloading rack can be a fixed unloading rack, which is installed on the side of the chip blowing rack away from the machine tool to transport the parts after chip blowing from the ground to a high place or to transport the parts to be processed from a high place to the ground.

[0053] The number of industrial robots is single, that is, a single industrial robot is used to manipulate multiple machine tools and corresponding material racks, thereby reducing the number of industrial robots used, improving the efficiency of the use of industrial robots, and reducing the number of industrial robots used in traditional processing and reducing the corresponding costs. The industrial robot is located between multiple chip blowing racks and multiple unloading racks, and is used to transport parts between multiple machine tools and multiple loading racks, and / or, to transport parts between multiple chip blowing racks and multiple loading racks.

[0054] The positioning sensor is arranged on the industrial robot to detect the status of the parts. Specifically, the positioning sensor may include a visual positioning device and a laser ranging device. Figure 2 As shown, the camera in the visual positioning device can be used to take pictures of the parts, and the image processing unit of the visual positioning device processes the parts picture and feeds back the parts coordinate data to the industrial robot, thereby controlling the servo motors of each joint of the robot to achieve part grasping; the ranging system measures the distance from the bottom surface of the system parts to the luminous surface of the ranging system, and converts the measured analog signal into a digital signal through the data conversion unit, and transmits the data to the control unit, and the workpiece position compensation is achieved by the robot.

By arranging multiple machine tools in parallel, a chip blowing rack is placed in front of the operating side of each machine tool, a robot is placed in front of the chip blowing rack, and a loading rack and an unloading rack are placed in front of the robot. The one-to-many loading and unloading method is adopted, and the robot covers the loading and unloading of all workstations, which greatly saves the space required for production. In combination with the actual machining time, one robot is used to cooperate with multiple machine tools for loading and unloading operations, which greatly saves costs.

Parts to be inspected can be placed. Parts to be inspected are parts that require manual quality inspection to determine whether they meet production requirements. Thereby, the parts to be inspected are divided into qualified products, scrapped products, returned products, etc. The industrial robot can also transport the parts to be inspected between multiple chip blowing racks and sampling storage location racks, so that the transportation and inspection of the parts to be inspected can be automated.

[0060] Furthermore, the loading rack comprises:

[0076] Reference Figure 3 , shows a flowchart of a method for processing parts based on a parts processing system according to an embodiment of the present invention, which is applied to a host computer, the host computer is connected to the parts processing system, and the parts processing system includes the parts processing system as described above; the specific steps may include:

[0077] Step 301, obtaining a detection signal of a positioning sensor;

[0078] In the embodiment of the present invention, the detection signal of the positioning sensor can be first obtained, and the detection signal of the positioning sensor can include various position parameters of the parts in the processing process, or the position parameters of the parts in the corresponding material rack.

[0079] Step 302, based on the detection signal, control the industrial robot to move between the machine tool, the chip blowing rack, the loading rack and the unloading rack.

[0080] By processing the detection signal to determine the status and location of the parts, the parts are moved accordingly, and the industrial robot is controlled to clamp the parts and move them between the machine tool, chip blowing rack, loading rack and unloading rack, so as to place them in the corresponding position and realize the automation of the processing process.

During the alarm period, the system automatically shields the material rack without affecting the production of the line, and the same applies to other material racks. The chip blowing rack has double workstations, and each workstation is equipped with a travel switch to detect whether there is material at the workstation. Since the chip blowing time is long, the robot places the workpiece at the empty material position each time and then takes away the workpiece that has been blown off after the last placement, which is more efficient and time-saving.
