[0026] In order to better understand the purpose, structure and function of the present invention, the present invention is described in further detail below with reference to the accompanying drawings.

[0027] like Figures 1 to 7 As shown, the utility model provides a metal chip and cutting fluid classification compression recovery processor, including a Mecanum wheel mobile chassis system 13, a chip collection and storage system 14, a chip pre-compression system 15, a chip final compression system 16 and a cutting fluid collection and discharge system 17; the chip collection and storage system 14 is installed on the Mecanum wheel mobile chassis system 13, the chip pre-compression system 15 is installed on the chip collection and storage system 14, the chip final compression system 16 is installed at the front and rear ends of the chip collection and storage system 14, and the cutting fluid collection and discharge system 17 is installed on the Mecanum wheel mobile chassis system 13 and is connected to the chip collection and storage system 14.

[0028] like Figure 1 、 Figure 3 As shown, the Mecanum wheel mobile chassis system 13 includes a chassis 2, a top plate 4, multiple Mecanum wheels 1 and multiple support columns 3; multiple Mecanum wheels 1 are installed on the chassis 2, and the top plate 4 is installed parallel to the chassis 2 through multiple support columns 3.

[0029] The Mecanum wheel mobile chassis system 13 enables omnidirectional movement on the site. Considering the confined workshop environment, the recycling processor requires strong maneuverability and flexibility. The Mecanum wheel design can well adapt to the complex workshop floor environment, such as potholes and slopes, to ensure the stable operation of the recycling processor. The Mecanum wheel axle layout and control algorithm design ensure accurate positioning and flexible control of the recycling processor.

[0030] like Figure 1 、 Figure 3As shown, the chip collection and storage system 14 includes a housing 24 mounted on the upper surface of the top plate 4. The housing 24 consists of an upper feed section 25 and a lower storage section 26. One side panel of the feed section 25 is tilted to facilitate feeding. The recycling processor collects chips (mostly fragments and flocculents) generated by milling and grinding and temporarily stores them in the housing 24.

[0031] like Figures 1 to 4 As shown, the chip pre-compression system 15 includes a pre-compression reduction motor 7, a driving gear 8, a driven gear 27, two pre-compression worms 22, and two driving gears 23; the two pre-compression worms 22 are parallel and rotatably installed at the junction of the feeding part 25 and the storage part 26 of the box body 24, and the helical teeth of the two pre-compression worms 22 are cross-arranged, and the driving gears 23 are fixed on the rod bodies at one end of the two pre-compression worms 22 extending outside the box body 24, and the two driving gears 23 are meshed and connected, and a driven gear 27 is installed on the rod body at the other end of one of the pre-compression worms 22 extending outside the box body 24, and the driven gear 27 is meshed and connected with the driving gear 8, and the driving gear 8 is fixed on the output shaft of the pre-compression reduction motor 7, and the pre-compression reduction motor 7 is fixed on the outside of the box body 24.

[0032] When it is recognized that the chip box is full, the pre-compression reduction motor 7 is driven to drive the driving gear 8 to rotate (the transmission direction is as follows Figure 4 (as shown), an externally meshing driven gear 27 is mounted on the same side, responsible for transmitting force and motion. This external meshing design ensures that the two pre-compression worms 22 move toward each other during transmission, achieving chip feeding and pre-compression. Furthermore, the number of teeth on the driving gear 8 is greater than that on the driven gear 27, achieving a single-stage reduction and increasing the output torque. This design reduces the chip volume to a certain extent, facilitating the final compression step, improving compression efficiency and quality, and simultaneously resolving the issue of excessive compression mechanism size.

[0033] like Figures 1 to 3 、 Figure 6 As shown, the chip final compression system 16 includes a compression servo 5, a compression plate 6, a movable door 12, and a scissor-type telescopic mechanism 28; the front and rear side walls of the storage part 26 of the box 24 are a compression plate 6 that can move forward and backward and a movable door 12 that can be flipped up and down, and a scissor-type telescopic mechanism 28 arranged along the front and back is installed between the compression plate 6 and the top plate 4, and a transmission gear is installed on one of the scissor-type telescopic mechanism 28's scissor rods, and the transmission gear is meshed with the servo gear, and the servo gear is installed on the compression servo 5, and the compression servo 5 is installed on the scissor-type telescopic mechanism 28's scissor rods, the upper end of the movable door 12 is hinged to the side wall corresponding to the box 24, and a door opening system 18 is installed between the movable door 12 and the box 24.

[0034] The main control board drives the compression steering gear 5 to operate and realize compression. When the output angle of the compression steering gear 5 increases (rotates clockwise), the movement direction of the scissor rod of the scissor-type telescopic mechanism 28 is as follows: Figure 6 As shown, the compression function is achieved. When the compression servo 5 output angle increases or decreases (rotates counterclockwise), the scissor rods of the scissor-type telescopic mechanism 28 move in the opposite direction, and the compression plate 6 retracts to the front end. At this point, the space within the box 24 is maximized, and the chips are pre-compressed and fed into the box. This design has the advantages of compact structure, high transmission efficiency, low cost, simple control, and high output torque.

[0035] like Figures 1 to 3 、 Figure 7 As shown, the door opening system 18 includes a trapdoor servo 9 (trapdoor servo MG996R), a rocker 10, and a pressure rod 11; the lower end of the pressure rod 11 is hinged to the lower end of the outer side surface of the movable door 12, the upper end of the pressure rod 11 is hinged to the lower end of the rocker 10, the upper end of the rocker 10 is connected to the output shaft of the trapdoor servo 9, and the trapdoor servo 9 is fixed on the outer side wall of the box 24.

[0036] The trapdoor servo 9 and the compression servo 5 use high-torque digital servos to ensure that the pressure applied to the chips during compression is sufficient, thus solving the problem of insufficient output torque of the compression mechanism.

[0037] Compressed chips centralized collection and processing: This section utilizes a rocker mechanism. The assembly positions of rocker 10 and compression rod 11 were simulated and calculated, analyzing the forces acting on movable door 12 during compression to determine rod length and assembly position parameters. During compression, movable door 12 remains closed. Upon completion, the recycling unit travels to the designated chip processing location, activates the rear trapdoor servo 9 to open movable door 12, and drives the front compression servo 5 to push the compressed chips out of the box 24 via the scissor-type telescopic mechanism 28 and compression plate 6.

[0038] like Figure 1 、 Figure 5 As shown, the cutting fluid collection and discharge system 17 includes a water pump plastic pipe 19, a cutting fluid collection box 20 and a fixed chute 21; the cutting fluid collection box 20 is slidably installed on the lower bottom surface of the top plate 4 through the fixed chute 21, and a cutting fluid drain port 29 is opened at the bottom of the box body 24 to communicate with the cutting fluid collection box 20, a water pump plastic pipe 19 is installed on the cutting fluid collection box 20, a submersible motor 30 is built into the cutting fluid collection box 20, and the submersible motor 30 is communicated with the water pump plastic pipe 19, and a water level monitoring device is installed in the cutting fluid collection box 20.

[0039] In processes such as turning, milling, planing, and grinding, in order to prevent deformation of the metal workpiece due to contact with the tool due to excessive temperature, cutting fluid will be sprayed to the contact position. The cutting fluid is collected by the recovery processor together with the chips, and flows through the cutting fluid drain port 29 at the bottom to the cutting fluid collection box 20 installed at the bottom. A water level monitoring device is installed in the cutting fluid collection box 20. When the water level exceeds 3 / 4 of the box body 24, the recovery processor moves to the designated location and discharges the cutting fluid in the cutting fluid collection box 20 through the water pump plastic pipe 19, thereby solving the problem of cutting fluid collection.

[0040] This utility model realizes automatic path planning of the intelligent material cart and achieves the purpose of automatic chip classification through a program that controls the movement of the cart based on YOLO visual recognition and a Gmapping algorithm map construction and navigation based on the ROS operating system and equipped with a laser radar.

[0041] The utility model uses K210 as the main control chip for identification, and uses the camera to identify different tracks. When the corresponding number is detected, the identified number and probability are displayed on the screen, and communication is established with the microcontroller through USART. Then, the movement trajectory of the car is controlled according to the identification result to realize automatic planning.

[0042] The utility model utilizes laser sensors and ultrasonic sensors for safety monitoring and has obstacle avoidance functions. An emergency stop switch and automatic parking functions are also designed to ensure the safety of the staff.

[0043] The cutting fluid collection box 20 uses a camera and a sensor to monitor the changes in the cutting volume in the box in real time (capacity <70% - green light is always on; capacity >75% - yellow light reminder; capacity >85% - red light warning) so that the cutting fluid collection box 20 can be cleaned in time.

[0044] This utility model enables automatic tracking: the operator selects a corresponding number based on the material being processed through the remote control. The number is then recognized using the grid detection of the YOLOv2 convolutional neural network on the K210 (main control chip). The NCN model conversion tool converts this number into a KModel model, which is then recognized with the aid of a camera to distinguish between different tracks. When a corresponding number is detected, the screen displays the recognized number and probability. Communication with the microcontroller is established via the USART, allowing the recovery processor to automatically plan its trajectory. This allows for safe and efficient processing of sorted chips, preventing secondary contamination. After dumping, the recovery processor automatically returns to its original position to await new chips.
