Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy door and window processing equipment, and in particular to a fully automatic CNC four-corner assembly production line for aluminum alloy doors and windows. Background Art

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] At present, with the popularization and development of aluminum alloy doors and windows, aluminum alloy door and window processing enterprises are developing towards the direction of intensive and standardized modernization. With the continuous development and growth of aluminum alloy door and window processing enterprises, more and more large and medium-sized aluminum alloy door and window processing enterprises at home and abroad need stable, reliable, suitable for aluminum alloy door and window processing industry, and highly automated production lines. Corner assembly is a key step in the production of aluminum alloy doors and windows. The existing aluminum alloy door and window corner assembly equipment includes single-corner assembly machine, double-headed angle assembly machine, and vertical four-headed angle assembly machine. The single-headed angle assembly machine needs to assemble the four corners of the door and window separately in turn, and each corner needs to be repeatedly positioned during the angle assembly process. Therefore, the labor intensity of manual labor is high, the production efficiency is low, the product quality is difficult to guarantee, and the defective rate is high. The double-headed angle assembly machine needs to divide the four corners of the door and window into two groups, assembling two corners each time, and repeat positioning twice during the angle assembly process. Therefore, compared with the single-headed angle assembly machine, the labor intensity of the double-headed angle assembly machine is reduced, and the production efficiency is improved, but the product quality is still difficult to guarantee, and the defective rate is high. The vertical four-head corner assembly machine can complete the positioning and corner assembly of the four corners of aluminum alloy doors and windows at one time, thereby improving production efficiency. However, the inventor found that the vertical four-head corner assembly machine uses eight cylinders to assemble the corners simultaneously. Since the oil pressure of the eight cylinders cannot be exactly the same, the eight cylinders are out of sync and the acting forces are not synchronized, resulting in problems such as misalignment of the aluminum alloy door and window corners, affecting product quality. Since the vertical four-head corner assembly machine uses manual single-thread loading, the manual labor intensity of the vertical four-head corner assembly machine is high. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a fully automatic CNC four-corner assembly production line for aluminum alloy doors and windows, which can automatically load and unload materials, has low labor intensity, avoids the phenomenon of corner assembly dislocation, and ensures product quality.

[0084] In order to facilitate subsequent processing and management, a barcode printer is also installed on the operating table.

[0085] The working method of this embodiment is:

[0086] The aluminum alloy profiles are assembled into aluminum alloy door and window frames on the angle code assembly table through the angle code. After the assembly, the aluminum alloy door and window frames are manually or automatically placed on the synchronous belt A61 and the synchronous belt B73 of the feeding and conveying table, and then positioned by the positioning guide wheel 49 and the positioning plate 50. After positioning, the start button is pressed, and the synchronous belt A61 and the synchronous belt B73 are driven to rotate by the motor A55 and the motor B67 respectively to transmit the aluminum alloy door and window frames to the synchronous belt C152 and the synchronous belt D165 of the four-corner assembly machine 2. The synchronous belt C152 and the synchronous belt D165 are driven to rotate by the motor C146 and the motor D159 respectively. When the photoelectric switch A62 senses that the second frame of the aluminum alloy door and window frame is transmitted from the feeding and conveying table to the synchronous belt C152 and the synchronous belt D165, the motor A55 and the motor B67 stop rotating, that is, the synchronous belt A61 and the synchronous belt B73 stop rotating and transmitting. At this time, the staff continues to put the assembled aluminum alloy door and window frames on the synchronous belt A61 and the synchronous belt B73 of the feed transmission platform, and after positioning them through the positioning guide wheel 49 and the positioning plate 50, they wait for the four-corner corner assembly machine 2 to complete the corner assembly and then continue to be transmitted to the four-corner corner assembly machine 2.

[0087] When the photoelectric switch B 153 senses the first frame of the aluminum alloy door and window frame, the positioning device A 154 and the positioning device B166 rise, and at the same time, the motor C146 and the motor D159 stop rotating, that is, the synchronous belt C152 and the synchronous belt D165 stop rotating and transmitting. Relying on the inertia of the motor C146 and the motor D159 when they stop rotating, the synchronous belt C152 and the synchronous belt D165 slowly stop rotating and transmitting, slowly bumping the aluminum alloy door and window frame against the positioning device A 154 and the positioning device B166, and then stopping transmission. After the aluminum alloy door and window frame collides with the positioning device A154 and the positioning device B166, the positioning device A 154 and positioning device B166 fall back to their positions, and then the servo motors of beam A component 10, beam B component 11, corner component B13, and corner component D15 cooperate to drive the corner assembly workbench of the four-corner corner assembly machine to quickly move to the bottom of the aluminum alloy door and window frame. After moving into position, the fixed conveyor belt lifting device 142 and the fixed conveyor belt lifting device 2 155 drop 16-fixed conveyor belt component B and 17-movable conveyor belt component B below the workbench, and the aluminum alloy door and window frame falls onto the corner assembly 118-workbench plate, and then the 105-servo motor C corresponding to each component 12-corner assembly component A, 13-corner assembly component B, 14-corner assembly component C, and 15-corner assembly component D drives the pallet A component to drive the 38-external positioning device and 119-positioning support plate on the 118-workbench plate to move and position the outer corner of the aluminum alloy door and window frame. , when the 38-external positioning device and the 119-positioning support plate are positioned, the 39-internal positioning device starts to position the inner corner of the aluminum alloy door and window frame driven by the cylinder. When the inner corner of the aluminum alloy door and window frame is positioned, the 37-pressing device presses the aluminum alloy door and window frame, and then the 114-servo motor D corresponding to the 12-corner component A, 13-corner component B, 14-corner component C, and 15-corner component D drives the 120-support plate B to the position to be assembled. After arriving at the position, the 127-servo motor E and the 137-servo motor F corresponding to the 12-corner component A, 13-corner component B, 14-corner component C, and 15-corner component D simultaneously drive the 124-corner knife seat A and the 134-corner knife B to drive the corresponding 40-corner knife to move the corner to connect the aluminum alloy door and window frame into an aluminum alloy door and window. After the cornering is completed, 40-cornering knife, 37-pressing device, 39-inner positioning device return to their original positions in sequence, 38-outer positioning device and 119-positioning support plate return to the transmission position, and then 142-fixed conveyor belt lifting device 1 and 155-movable conveyor belt lifting device 1, the first lifting fixed conveyor belt component 16 and the second lifting fixed conveyor belt component 17 rise above the workbench, and after rising into place, motor C146 and motor D159 are started to drive synchronous belt C152 and synchronous belt D165 to rotate and transmit the aluminum alloy doors and windows to the discharge conveying platform 3.

[0088] When the photoelectric switch C180 on the discharge conveyor platform 3 senses the first frame of the aluminum alloy doors and windows, the aluminum alloy doors and windows have all been transferred to the discharge conveyor platform 3, and the fixed conveyor belt lifting device 168 and the mobile conveyor belt lifting device 181 drop the discharge fixed conveyor belt component 19 and the discharge mobile conveyor belt component 20 to the position to be stacked. When the new fully automatic CNC four-corner assembly production line for aluminum alloy doors and windows is not connected to the hardware assembly workbench, the motor E173 and the motor F186 stop rotating, that is, the synchronous belt E179 and the synchronous belt F192 stop rotating and transmitting, waiting for the manual or automatic stacker to transport the aluminum alloy doors and windows. When the new fully automatic CNC four-corner assembly production line for aluminum alloy doors and windows is connected to the hardware assembly workbench, the motor E173 and the motor F186 continue to rotate to drive the synchronous belt E179 and the synchronous belt F192 to rotate and transmit the aluminum alloy doors and windows to the hardware assembly workbench. When the photoelectric switch C180 on the discharging conveying platform 3 senses the first frame of the aluminum alloy door and window, the motor A55 and the motor B67 of the feeding conveying platform 1 are started to drive the synchronous belt A61 and the synchronous belt B73 to rotate and transmit to start the next aluminum alloy door and window frame corner assembly.

[0089] The feeding conveying platform, the four-corner assembly machine, and the discharging conveying platform are sequentially connected to the same assembly line, and the discharging conveying platform can be raised and lowered and connected to the subsequent hardware assembly workbench, so that the present invention realizes a new fully automatic CNC four-corner assembly production line for aluminum alloy doors and windows, which can effectively improve production efficiency and effectively reduce manual labor intensity.

Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
