Description

Technical fields:

[0001] This utility model relates to the field of CNC feeding machine technology, and specifically to a CNC automatic feeding device. Background technology:

[0002] With the continuous development of industrial automation technology, CNC machining is being applied more and more widely. While developing rapidly, people are also placing increasingly higher demands on its safety, efficiency, and spatial layout. In the past, CNC machine tools could not achieve automatic feeding and unloading processes, and manual feeding was generally used. The specific operation was as follows: the operator would feed a piece of material to be processed onto the machining spindle inside the CNC machine tool, then close the safety door. After the CNC machine tool finished processing, the operator would open the safety door and remove the material, and this cycle would be repeated.

[0003] Currently available automated loading and unloading machines can automatically load and unload CNC machine tools. For example, Chinese utility model patent application CN 207997162U discloses an automated CNC warehouse loading and unloading machine, which includes: a frame, a loading and unloading functional area, an electrical distribution box, and three-color warning lights. The frame contains an air source processing unit, and the loading and unloading functional area is located on top of the frame. A front safety door is located on one side of the loading and unloading functional area, and a rear safety door is located on the other side. A material frame is located on the bottom of the loading and unloading functional area, and an XYZ transport arm is located above the material frame. The CNC loading and unloading robotic arm uses a combination of servo motors, lifting cylinders, and a synchronous belt transmission unit to double the stroke of the robotic arm, and the stroke is adjustable.

[0004] However, this existing CNC automated material handling machine uses a combination of servo motors, lifting cylinders, and synchronous belt transmission units to transport materials. The robotic arm is an XYZ handling arm, capable of movement only in three axes. However, during long-stroke operations, positioning inaccuracies are prone to occur. Furthermore, its material frames lack a stacking mechanism, making it difficult to effectively arrange and stack materials, resulting in low space utilization. Additionally, in this technical solution, the safety doors for the loading and unloading areas are located at the front and rear, requiring loading and unloading from the front of the CNC machine. Front loading and unloading can easily interfere with operators adjusting the equipment, is detrimental to space layout, and can negatively impact production safety and operational convenience.

[0028] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0029] See Figures 1 to 11 As shown, a CNC automatic feeding device includes: a CNC main body 1 and a feeding machine 2 disposed beside the CNC main body 1 for automatically feeding materials onto the CNC main body 1.

[0030] The CNC main body 1 is equipped with an automatic door 11 for loading and unloading materials by the feeding machine 2. The feeding machine 2 includes a main frame 21, a four-axis robotic arm 22 disposed within the main frame 21 for loading and unloading materials onto the CNC main body 1, a lifting and stacking mechanism 23 disposed within the main frame 21 for stacking materials by lifting and lowering, an auxiliary positioning mechanism 24 disposed within the main frame 21 for flipping and positioning materials, a feeding electrical box 25 disposed within the main frame 21, and a protective cover mechanism 26 disposed around the main frame 21 for enhanced protection. The feeding electrical box 25 is responsible for receiving processing instructions and coordinating the four-axis robotic arm 22, the lifting and stacking mechanism 23, and the auxiliary positioning mechanism 24 to achieve full automation of material positioning, gripping, and conveying. Furthermore, in this invention, the protective cover mechanism 26 completely surrounds and protects the main frame 21, greatly improving production safety.

[0031] This invention changes the traditional CNC equipment's front-mounted loading mechanism. By installing an automatic door 11 beside the CNC main body 1, the loading machine 2 is positioned to the side of the CNC main body 1, performing loading and unloading operations from the side. This avoids the problem of front-mounted loading interfering with operator adjustments, effectively optimizing space layout, enhancing safety and ease of operation, and achieving a high degree of automation, enabling fully automatic unattended operation. It is suitable for widespread application in various CNC automatic loading equipment. Furthermore, compared to existing structures, this invention uses an auxiliary positioning mechanism 24 to rotate and position materials with high accuracy. A four-axis robotic arm 22 grips materials for loading and unloading, covering a wide area. A lifting and stacking mechanism 23 lifts and lowers the pallet 215, optimizing space utilization and enhancing material storage capacity, allowing for material replacement every 4 to 6 hours, effectively saving labor costs.

[0032] The main frame 21 includes four supporting legs 211, a base 212 positioned above and supported by the legs 211, a frame 213 mounted on the base 212, a three-color light 214 mounted on the frame 213 for indicating loading information, and a pallet 215 mounted on the base 212 for carrying materials. A clearance door 219 for matching with the automatic door 11 is provided on one side of the frame 213. Here, there are two lifting and stacking mechanisms 23 and two pallets 215, used to store materials to be processed and processed materials respectively. Preferably, multiple guide columns 220 are vertically mounted on the base 212 to guide the pallets 215. The lifting and stacking mechanisms 23 are positioned below the pallets 215 and are used to raise or lower the pallets 215 containing materials, facilitating gripping by the four-axis robotic arm 22.

The second X-axis module 6, driven by the first X-axis module 3, can laterally pass through the clearance door 219 and the automatic door 11, and drives the robotic gripper module 7 to move back and forth between the CNC main body 1 and the loading machine 2 to achieve precise loading and unloading.

The system includes a first X-axis drive shaft 38 between the second rack 36, a first X-axis motor 39 for driving the first X-axis drive shaft 38, a first synchronous pulley 310 mounted on the output shaft of the first X-axis motor 39, a second synchronous pulley 311 fixed on the first X-axis drive shaft 38, a first synchronous belt 312 sleeved around the first synchronous pulley 310 and the second synchronous pulley 311, and a first spur gear 313 and a second spur gear 314 mounted on the first X-axis drive shaft 38 for meshing with the first rack 35 and the second rack 36, respectively. Here, the first X-axis module 3 is located at the upper end of the main frame 21, and the first X-axis module 3 almost bears the weight of the entire four-axis manipulator mechanism 22. Therefore, the first X-axis module 3 adopts a dual-guide structure of slide rail-slider and rack-gear to improve the load-bearing capacity of the first X-axis module 3, ensure smooth operation, and avoid affecting positioning accuracy due to operational jamming.

[0035] The Y-axis module 4 includes a Y-axis slide rail 41 mounted between the first X-axis slider 33 and the second X-axis slider 34, a Y-axis slider 42 mounted on the Y-axis slide rail 41, a Y-axis moving plate 43 mounted on the Y-axis slider 42, and a Y-axis motor 44 mounted on one side of the Y-axis moving plate 43; the Z-axis module 5 includes a Z-axis flat tube 51, a Z-axis slide rail 52 mounted on the Z-axis flat tube 51, a Z-axis slider 53 mounted on the Z-axis slide rail 52 and fixed to the Y-axis moving plate 43, and a Z-axis motor 54 mounted at the lower end of the Y-axis moving plate 43; the second X-axis module 6 includes a second X-axis flat tube 61 mounted at the lower end of the Z-axis flat tube 51, a fourth X-axis slide rail 62 mounted on the second X-axis flat tube 61, a fourth X-axis slider 64 mounted on the fourth X-axis slide rail 62, and a second X-axis motor 63 mounted at one end of the second X-axis flat tube 61. Here, the first X-axis module 3, Y-axis module 4, Z-axis module 5 and the second X-axis module 6 work together to drive the robotic gripper module 7 to grab materials for loading and unloading, with high positioning accuracy and a large coverage area.

[0036] The robotic gripper module 7 includes an upper top plate 71 mounted on the fourth X-axis slider 64, a robotic cylinder 72 mounted on the lower end of the upper top plate 71, a robotic adapter plate 73 connected to the lower end of the robotic cylinder 72, a suction cup drive cylinder 74 mounted on one end of the robotic adapter plate 73, several vacuum suction cups 75 mounted below the suction cup drive cylinder 74 for picking up and transporting materials, a side posture cylinder 76 mounted on the other end of the robotic adapter plate 73, an L-shaped plate 77 hinged to the lower end of the side posture cylinder 76, a four-jaw gripper 78 mounted on one side of the L-shaped plate 77 for gripping and transporting materials, a secondary robotic gripper 79 mounted on the other side of the L-shaped plate 77 for gripping and transporting materials, and a sensing photoelectric sensor 70 mounted on the four-jaw gripper 78 for sensing materials. Here, in order to adapt to the handling of various materials, the robotic gripper module 7 is not only equipped with a vacuum suction cup 75, but also with a four-jaw gripper 78 and a secondary robotic gripper 79 through an L-shaped plate 77. This allows for different handling methods for different materials, greatly improving adaptability.

[0037] The lifting and stacking mechanism 23 includes a stacking base plate 231 disposed on the base 212, a lifting motor mounting plate 232 mounted on the stacking base plate 231, a lifting motor 233 mounted on one end of the lifting motor mounting plate 232, a lifting slide rail 234 vertically disposed on the lifting motor mounting plate 232, a sliding mounting plate 235 slidably disposed on the lifting slide rail 234, a main support plate 236 horizontally disposed on the sliding mounting plate 235, and a main support plate 236 disposed on the sliding mounting plate 235. The system includes a corner brace 237 mounted on the mounting plate 235 and supported at the lower end of the main support plate 236; a lead screw 238 vertically mounted on the lifting motor mounting plate 232; a lead screw nut 239 sleeved on the lead screw 238 and connected to the sliding mounting plate 235; a third synchronous pulley 2301 mounted on the output shaft of the lifting motor 233; a fourth synchronous pulley 2302 located at the lower end of the lead screw 238; and a third synchronous belt 2303 sleeved around the third synchronous pulley 2301 and the fourth synchronous pulley 2302. Here, the main support plate 236 supports the tray 215 from below to drive the tray 215 to rise and fall. The corner brace 237 further enhances the load-bearing capacity, and the use of the lead screw 238 and lead screw nut 239 for transmission makes the sliding mounting plate 235 more stable during the lifting and falling process.

[0038] The auxiliary positioning mechanism 24 includes a frame main board 241 mounted on the feeding electrical box 25, a cylinder support mounting plate 242 mounted on the frame main board 241, a first tilting cylinder 243 mounted on the upper end of the cylinder support mounting plate 242, a cylinder adapter plate 244 mounted on the first tilting cylinder 243, a first gripper 245 and a second gripper 246 mounted on the cylinder adapter plate 244, a cylinder support seat 247 mounted on the frame main board 241, a second rotary cylinder 248 mounted on the cylinder support seat 247, a positioning disk 249 mounted on the second rotary cylinder 248 and driven by the second rotary cylinder 248 to perform planar tilting, and a water tank 240 mounted at one end of the frame main board 241. Here, during the material loading process, after the robotic gripper module 7 picks up the material, the photoelectric sensor 70 detects the material's orientation using diffuse reflected light. If it does not correspond to the preset orientation, it will be corrected by the auxiliary positioning mechanism 24. Specifically, the first flipping cylinder 243 drives the first gripper 245 and the second gripper 246 to grip and flip the material, while the second rotating cylinder 248 drives the positioning disk 249 to rotate, ensuring that the material enters the CNC body 1 in the correct orientation for processing. Additionally, the water tank 240 is used to clean the processed material.

[0039] The feeding electrical box 25 includes an electrical box body 251 disposed within the main frame 21 for providing power distribution, a first fan 252 disposed on one side of the electrical box body 251 for drawing outside air into the electrical box body 251, and a second fan 253 disposed on the other side of the electrical box body 251 for drawing hot air out of the electrical box body 251 in conjunction with the first fan 252 for heat dissipation.

[0040] In summary, this invention changes the traditional CNC equipment's front-mounted loading mechanism. By installing an automatic door 11 on the side of the CNC main body 1, the loading machine 2 is positioned beside the CNC main body 1 and performs loading and unloading operations from the side. This avoids the problem of front-mounted loading affecting operators' equipment debugging, effectively optimizes the spatial layout, enhances safety and ease of operation, and has a high degree of automation, enabling fully automatic unattended operation. It is suitable for widespread application in various CNC automatic loading equipment. Furthermore, compared with existing structures, this invention uses an auxiliary positioning mechanism 24 to drive the material for flipping and positioning, achieving high positioning accuracy.
