Description

Technical Field

[0001] This invention belongs to the field of aluminum machinery technology, specifically referring to a high-efficiency processing method for aluminum profiles for doors and windows with dual-station combination and a corresponding dual-workstation production line. Background Technology

[0002] With the rapid development of industrial automation, the processing of aluminum profiles for doors and windows has also quickly entered the field of high-efficiency, highly automated, and highly intelligent processing. This has led to the emergence of related automated processing flows for aluminum profiles for doors and windows, as well as corresponding structures and workstation production lines integrating sawing, milling, drilling, and other processes. Currently, the application of workstations uses a single composite machining center area combined with automatic feeding, delivery, and unloading processes as the basic process logic framework. The composite machining center area integrates sawing, milling, drilling, laser scribing, grooving, and other processes. This process logic is based on the traditional single-machine processing logic, that is, the flow of a production line composed of multiple sets of single machines, replacing manual labor with automated production logic, and replacing the multiple sets of single machines plus buffering with workstation production lines. However, the workstation production line model based on this traditional process logic has a very significant drawback: efficiency optimization! Traditional manual labor combined with multiple stand-alone machines offers great flexibility and control in terms of machine technology, efficiency, and personnel application, as humans play a leading role. This allows for flexible allocation and application based on different profile types, processing quantities, and the working efficiency of different stand-alone machines, ensuring effective production capacity. However, the workstation production line model directly inherited from this work logic has fixed execution positions and sequences for all processes. This makes it impossible to optimize execution based on different profile types, achieve high-efficiency output from workstations, or effectively differentiate between fine and rough processing. Either some functions are not needed in certain profile processing, resulting in wasted resources; or some functions, due to slow efficiency at certain points, affect the efficiency of other points, preventing high-efficiency processing; furthermore, the complex nature of the processing areas leads to all processes being treated as fine finishing, resulting in wasted processing efficiency and increased processing costs. To address this, a high-efficiency processing method combining two workstations for aluminum profiles for doors and windows, and a corresponding dual-workstation production line, are proposed. This method breaks with conventional thinking, transforming the traditional production line model of process logic flow into a logical framework of automatic feeding, automatic material feeding, automatic processing, intermediate transfer, and automatic material discharge in a dual composite processing center area. It also optimizes the distinction between fine and rough processing, greatly improving the working efficiency of each process node, reducing the waiting time of high-efficiency nodes, improving product utilization efficiency, increasing production capacity, and reflecting the highly composite and intelligent characteristics of automated production.

[0019] This solution also discloses a high-efficiency processing method for dual-station assembly of aluminum profiles for doors and windows, which mainly includes the following steps: The first step is to manually feed the material onto the synchronous conveyor belt assembly. Through the action of the feeding conveyor motor and the feeding conveyor synchronous shaft assembly, the profile is brought to the feeding and positioning assembly. The second step involves using the synchronous lifting transmission assembly to smoothly lift the aluminum profile, which in turn drives the bottom support roller assembly to lift the profile off the synchronous transmission belt assembly. The third step involves using the cylinder in the hooking mechanism to retract and drive the hooking bearing rollers to press the profile backward onto the first rear positioning roller group, thus achieving initial transfer and positioning of the profile in the Y direction. Then, the cylinder in the upper pressing mechanism performs an ejection action to achieve upper pressing of the profile and complete the transfer and positioning. Fourth, the feeding robot arm assembly reaches the leftmost end of the profile under servo drive, and the robot arm clamps the profile to perform the feeding action; Fifth step: When the rightmost end of the profile reaches the incoming material inspection auxiliary clamping component, the profile touches the inspection plate and continues to move forward, driving the inspection hinge to move, pushing the inspection cylinder to trigger the limit switch, and completing the incoming material inspection work; Step 6: Under program control, the forward drilling and milling head assembly and the reverse drilling and milling head assembly reach the machining position along the linear guideway and the circular guideway. Step 7: As the machining head moves, the feeding robot arm assembly grips the profile and moves forward to the high-speed drilling and milling machining area composed of the forward drilling and milling head assembly and the reverse drilling and milling head assembly. Step 8: After the profile is in place, the rodless cylinder performs a clamping action, driving the auxiliary side clamping block to clamp the profile to the auxiliary rear positioning plate. At the same time, the clamping feed cylinder pushes out, so that the auxiliary upper clamping is in place. The auxiliary clamping cylinder and the auxiliary clamping pneumatic component perform an upper clamping action, so that the upper clamping block clamps the upper surface of the profile. At the same time, the front clamping pneumatic component in the machine head clamping and positioning mechanism performs a clamping action, so that the front clamping roller group pushes the profile to the second rear positioning roller group. The upper clamping pneumatic component performs an upper clamping action, so that the upper clamping roller group clamps the profile to the bottom roller group. Step 9: The forward drilling and milling head assembly and the reverse drilling and milling head assembly perform high-speed drilling and milling; Step 10: When the feeding robot arm assembly reaches the position of the incoming material detection auxiliary clamping assembly, all the auxiliary clamping in the incoming material detection auxiliary clamping assembly is released to avoid it, and at the same time, it is converted into the intermediate material transfer assembly of the intermediate transmission buffer area of ​​the intermediate transmission buffer mechanism to perform the auxiliary clamping work of high-speed sawing and milling. Step 11: After high-speed milling is completed, the feeding robot assembly sends the profile out of the high-speed drilling and milling working area of ​​the high-speed drilling and milling mechanism and into the intermediate transmission buffer area of ​​the intermediate transmission buffer mechanism. Step 12: The turnover synchronous lifting mechanism performs the lifting action, which drives the turnover positioning roller assembly to receive the material. When the material enters the intermediate transmission buffer area of ​​the intermediate transmission buffer mechanism, the third bottom roller lifts the profile, and the hooking pneumatic assembly performs the hooking action, which drives the hooking bearing roller group to press the profile to the rear upright roller group. Step 13: The turnover synchronous lifting mechanism performs a lowering action, causing the third bottom roller to fall below the synchronous belt of the middle synchronous transmission component, thus placing the profile onto the synchronous transmission belt; Step 14: The intermediate synchronous transmission component performs synchronous belt transmission to transport the profile to the precision feeding area; Step 15: The precision feeding and positioning component performs the material-lifting action, and the profile is separated from the intermediate synchronous transmission component, and the initial positioning in the Y and Z directions is completed. Step 16: Under servo drive, the precision feeding robot arm reaches the profile clamping position and clamps the leftmost side of the profile, ready to precisely feed it into the composite processing center area. Step 17: The four-way sawing and milling unit reaches the precision milling position under servo drive, and at the same time the profile enters the composite machining center area; Step 18: Perform core sawing and milling positioning, clamping, milling, and sawing operations; Step 19: The finished product is held by the unloading robot arm and enters the unloading and receiving roller group in the unloading area of ​​the unloading mechanism. The unloading and receiving lifting pneumatic system performs the dropping action and puts the finished product onto the synchronous belt of the unloading synchronous belt transmission mechanism to complete the transmission and unloading. Step 20: Repeat the above process to complete the assembly line operation.

[0043] In practical use, the material is manually fed onto the synchronous conveyor belt assembly 15. The output of the drive motor rotates, driving the drive wheel 162 to rotate. The rotation of the drive wheel 162 drives the synchronous belt 161 to rotate. The rotation of the synchronous belt 161 drives the driven wheel 165 and the tension wheel 163 to rotate, thereby moving the workpiece on the synchronous belt 161. Through the action of the feeding transmission motor 16 and the feeding transmission synchronous shaft 17, the profile reaches the feeding positioning assembly 9.

The output of the robotic gripper cylinder 152 moves, driving one end of the control linkage 153 to move, which in turn drives the other end of the push rod 155 to move, thereby driving the robotic arm base 156 to move. The movement of the robotic arm base 156 drives the gripping robotic arm 157 to move. The output of the X-axis drive motor 146 moves, driving the rotating shaft 159 to rotate, thereby driving the gripper... The robotic arm 157 rotates, and the feeding robotic arm assembly 12, driven by a servo, reaches the leftmost end of the profile. The robotic arm grips the profile and performs the feeding action. When the rightmost end of the profile reaches the incoming material detection auxiliary clamping assembly 24, the profile touches the detection plate 30 and continues to move forward, driving the detection hinge 29 to move. This pushes the detection cylinder 27 to trigger the limit switch, completing the incoming material detection. Under program control, the drilling and milling forward head assembly 10 and the drilling and milling reverse head assembly 11 reach the processing position along the linear guide motion pair 46 and the circular guide motion pair 47. While the processing head moves, the feeding robotic arm assembly 12 grips the profile and moves forward to the high-speed drilling and milling processing area composed of the drilling and milling forward head assembly 10 and the drilling and milling reverse head assembly 11. After the profile is in place, the rodless cylinder 42 performs the clamping action.The auxiliary side clamping block 44 is driven to clamp the profile to the auxiliary rear positioning plate 45. At the same time, the clamping feed cylinder 34 is pushed out, so that the auxiliary upper clamping is in place. After that, the auxiliary clamping cylinder 37 and the auxiliary clamping pneumatic assembly perform the upper clamping action, so that the upper clamping block 38 clamps the upper surface of the profile. At the same time, the front clamping pneumatic assembly 65 in the machine head clamping and positioning mechanism performs the clamping action, so that the front clamping roller group 64 pushes the profile to the second rear positioning roller group 62. The upper clamping pneumatic assembly 60 performs the upper clamping action, so that the upper clamping roller group 61 clamps the profile to the bottom roller group 63. The drilling and milling forward machine head assembly 10 and the drilling and milling reverse machine head assembly 11 perform high-speed drilling and milling. The output end of the feed cylinder 201 moves, driving the fish-eye bearing 202 to move. The movement of the fish-eye bearing 202 drives the safety mechanism to move. The mounting shaft 207 moves, which in turn moves the moving plate 203, which in turn moves the electric spindle 206. The electric spindle 206 is used to drill holes in the workpiece. The drilling process of the front drilling and milling spindle assembly 55, the rear drilling and milling spindle assembly 56, and the lower drilling and milling spindle assembly 57 is the same as that of the upper drilling and milling spindle assembly 54. The output end of the hook cylinder 208 moves, which in turn moves the connecting block 213. The movement of the connecting block 213 moves the hook slide rail 210, which in turn moves the hook bearing roller 211. When the feeding robot assembly 12 reaches the position of the incoming material detection auxiliary clamping assembly 24, all the auxiliary clamping in the incoming material detection auxiliary clamping assembly 24 is released to avoid the material, and at the same time, it is converted into the intermediate transmission buffer mechanism 2. The intermediate material transfer component 72 in the transmission buffer area performs auxiliary clamping work for high-speed milling. After high-speed milling is completed, the feeding robot component 12 sends the profile out of the high-speed milling working area of ​​the high-speed drilling and milling mechanism 1 and into the intermediate transmission buffer area of ​​the intermediate transmission buffer mechanism 2. The turnover synchronous lifting mechanism 73 performs a lifting action, driving the turnover positioning roller component 74 to receive the material. When the material enters the intermediate transmission buffer area of ​​the intermediate transmission buffer mechanism 2, the third bottom roller 89 lifts the profile, and the hooking pneumatic component 93 performs a hooking action, driving the hooking bearing roller group 92 to press the profile to the rear upright roller group 90. The turnover synchronous lifting mechanism 73 performs a lowering action, causing the third bottom roller 89 to fall below the synchronous belt of the intermediate synchronous transmission component 70, realizing the placement of the profile to the synchronous belt. On the conveyor belt, the intermediate synchronous transmission component 70 synchronously transmits the profile to the precision feeding area 3. The precision feeding positioning component 9 lifts the profile and releases it from the intermediate synchronous transmission component 70, completing preliminary positioning in the Y and Z directions. The precision feeding robot 4, driven by a servo, reaches the profile clamping position and clamps the leftmost side of the profile, preparing for precise feeding into the composite processing center area 5. The four-way sawing and milling unit 106, driven by a servo, reaches the precision milling position. Simultaneously, the profile enters the composite processing center area 5 for core sawing and milling positioning, clamping, milling, and sawing actions. The finished material is clamped by the discharge robot 105 and enters the discharge receiving roller group 144 in the discharge area of ​​the discharge mechanism 6. The discharge receiving lifting pneumatic system 142 performs the dropping action.The finished material is placed onto the synchronous belt of the discharge synchronous belt conveyor 141 to complete the material transmission and discharge. This process is repeated to complete the assembly line operation. This is the overall workflow of the invention. This step can be repeated for subsequent uses.

10. A method for using a dual-workstation production line for high-efficiency processing of aluminum profiles for doors and windows, characterized in that, The high-efficiency dual-workstation production line for processing aluminum profiles for doors and windows according to claim 9 includes the following steps: The first step is to manually feed the material onto the synchronous conveyor belt assembly (15). Through the action of the feeding conveyor motor (16) and the feeding conveyor synchronous shaft (17), the profile reaches the feeding and positioning assembly (9). The second step is to use the synchronous lifting transmission assembly (19) to make the lifting aluminum profile (18) rise steadily, and drive the bottom support roller assembly (23) to lift the profile away from the synchronous transmission belt assembly (15). The third step is to use the cylinder in the hooking mechanism (20) to drive the hooking bearing roller to press the profile backward to the first rear positioning roller group (22) to achieve the initial transmission and positioning of the profile in the Y direction. Then, the cylinder in the upper pressing mechanism (21) performs the pushing action to achieve the upper pressing of the profile and complete the transmission and positioning. In the fourth step, the feeding robot assembly (12) reaches the leftmost end of the profile under servo drive, and the robot grips the profile to perform the feeding action; Fifth step: When the rightmost end of the profile reaches the incoming material inspection auxiliary clamping component (24), the profile touches the inspection plate (30) and continues to move forward, driving the inspection hinge (29) to move, pushing the inspection cylinder (27) to trigger the limit switch, and completing the incoming material inspection work; In the sixth step, the forward drilling head assembly (10) and the reverse drilling head assembly (11) reach the machining position under program control along the linear guide motion pair (46) and the circular guide motion pair (47); Step 7: While the machining head moves, the feeding robot assembly (12) clamps the profile and moves forward to the high-speed drilling and milling processing area composed of the forward drilling and milling head assembly (10) and the reverse drilling and milling head assembly (11). Step 8: After the profile is in place, the rodless cylinder (42) performs a pressing action, driving the auxiliary side pressing block (44) to press the profile to the auxiliary rear positioning plate (45). At the same time, the pressing feed cylinder (34) is pushed out, so that the auxiliary pressing cylinder (37) and the auxiliary pressing pneumatic assembly perform an upper pressing action, so that the upper pressing block (38) presses the upper surface of the profile. At the same time, the front pressing pneumatic assembly (65) in the machine head pressing and positioning mechanism performs a pressing action, so that the front pressing roller group (64) pushes the profile to press against the second rear positioning roller group (62). The upper pressing pneumatic assembly (60) performs an upper pressing action, so that the upper pressing roller group (61) presses the profile against the bottom roller group (63). In the ninth step, the forward drilling head assembly (10) and the reverse drilling head assembly (11) perform high-speed drilling and milling. The output end of the feed cylinder (201) moves to drive the fish-eye bearing (202) to move. The movement of the fish-eye bearing (202) drives the mounting shaft (207) to move. The movement of the mounting shaft (207) drives the moving plate (203) to move. The movement of the moving plate (203) drives the electric spindle (206) to move. The electric spindle (206) is used to drill holes in the workpiece. The drilling process of the front drilling spindle assembly (55), the rear drilling spindle assembly (56), and the lower drilling spindle assembly (57) is the same as that of the upper drilling spindle assembly (54). Step 10: When the feeding robot assembly (12) reaches the position of the incoming material detection auxiliary clamping assembly (24), the output end of the telescopic cylinder (26) moves to drive the second mounting plate (31) to move, the second mounting plate (31) moves to drive the detection mounting seat (28) to move, the detection mounting seat (28) moves to drive the detection plate (30) to move, the output end of the clamping feed cylinder (34) moves to drive the auxiliary rear positioning plate (45) to move, and the workpiece can be clamped by the auxiliary side clamping block (44). The output end of the auxiliary clamping cylinder (37) moves to drive the upper clamping block. (38) The workpiece can be clamped by the upper clamping block (38) and the auxiliary clamping table (41). All the auxiliary clamping in the auxiliary clamping assembly (24) of the incoming material detection is released to avoid it. At the same time, it is converted into the intermediate transfer buffer mechanism (2). The intermediate transfer assembly (72) of the intermediate transfer buffer area performs the auxiliary clamping work of high-speed sawing and milling. The vertical pneumatic transmission (78) output end moves to drive the pallet (79) to move up and down. The pallet (79) moves to drive the second bottom roller (80), the rear roller (81) and the rear vertical plate (82) to move up and down. Step 11: After high-speed milling is completed, the feeding robot assembly (12) sends the profile out of the high-speed drilling and milling mechanism (1) high-speed drilling and milling working area and into the intermediate transmission buffer mechanism (2) intermediate transmission buffer area. Step 12: The turnover synchronous lifting mechanism (73) performs the lifting action, driving the turnover positioning roller assembly (74) to receive the material. When the material enters the intermediate transmission buffer area of ​​the intermediate transmission buffer mechanism (2), the third bottom roller (89) lifts the profile, and the hooking pneumatic assembly (93) performs the hooking action, driving the hooking bearing roller assembly (92) to press the profile to the rear upright roller assembly (90). In the thirteenth step, the turnover synchronous lifting mechanism (73) performs a falling action, so that the third bottom roller (89) falls below the synchronous belt of the middle synchronous transmission component (70), thereby placing the profile onto the synchronous transmission belt; Step 14: The intermediate synchronous transmission component (70) performs synchronous belt transmission to transport the profile to the precision feeding area (3). Step 15: The precision feeding and positioning component (9) performs the material lifting action and causes the profile to detach from the intermediate synchronous transmission component (70), and completes the initial positioning in the Y and Z directions; Step 16: The precision feeding robot (4) reaches the profile clamping position under servo drive and clamps the leftmost side of the profile, ready to be precisely fed into the composite processing center area (5). Step 17: The four-way sawing and milling unit (106) reaches the precision milling position under servo drive, and at the same time the profile enters the composite machining center area (5). Step 18: The output end of the left clamping cylinder (217) moves, causing the left clamping column (218) to move downward. The downward movement of the left clamping column (218) causes the left clamping block (214) to move downward, using the left clamping block (214) to press the workpiece. The output end of the right clamping cylinder (223) moves, causing the right clamping column (224) to move downward. The downward movement of the right clamping column (224) causes the right clamping block (220) to move downward, using the right clamping block (220) to press the workpiece. The output end of the clamping positioning motor (226) rotates, driving the roller screw pair (22... 9) Rotation, the rotation of the roller screw pair (229) drives the synchronous slide (231) to rotate, the synchronous slide (231) moves and pushes the sliding guide (233) to move, the sliding guide (233) moves and drives the second connecting rod (234) to move, the output end of the clamping cylinder (238) moves and drives the upper pressure plate (245) to move downward to clamp the workpiece, the output end of the translation cylinder (240) moves and drives the clamping base plate (247) to move, so that the position of the upper pressure plate (245) can be adjusted to perform core milling positioning, clamping, milling and sawing actions; Step 19: The finished product is held by the discharge robot arm (105) and enters the discharge receiving roller group (144) of the discharge area of ​​the discharge mechanism (6). The discharge receiving lifting pneumatic system (142) performs the dropping action and puts the finished product onto the synchronous belt of the discharge synchronous belt transmission mechanism (141) to complete the transmission and discharge. Step 20: Repeat the above process to complete the assembly line operation.
