Description

Technical Field

[0001] This invention relates to the field of door and window processing technology, specifically to rapid processing equipment for aluminum alloy door and window frames. Background Technology

[0002] In the processing of aluminum alloy doors and windows, welding is required to strengthen the structural strength and complete the splicing of the frame. In existing technologies, the ends of the door and window frames are typically cut into an inclined structure, and then the inclined end faces of two frames are joined and welded together to form a stable right-angle connection. In practice, the door and window frames are usually positioned on a welding platform, and the welding operation is completed by a laser welding robot. During the welding process, the stability of the frame must be ensured to guarantee welding quality. An existing patent (publication number: CN118989592B) discloses a welding device for intelligent door and window processing. While this device can perform grinding on the ends of door and window frame parts, the inverted V-shaped support structure used makes it difficult to achieve stable positioning of the parts. This leads to frequent adjustments of the tooling position to calibrate the part's posture during subsequent inclined grinding and welding processes. This not only severely restricts the improvement of processing efficiency but also results in high workpiece temperatures after grinding, and frequent manual intervention can easily lead to safety risks. Summary of the Invention

Two window frame parts are placed on the surface of the supporting inclined plates so that the two window frame parts are set vertically. A notch is left between the upper ends of the two supporting inclined plates to allow space for grinding.

Detailed Implementation

[0008] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0009] refer to Figures 1-9 As shown, the rapid processing equipment for aluminum alloy door and window frames includes two supports 100. Each support 100 has a support leg 101 on its outer side. The two supports 100 are connected by a merging rod. Each support 100 has a transfer mechanism with multiple window frame positioning mechanisms 300 for locking the window frame plate 301. Above the transfer mechanism is a mounting plate 105, which is connected and fixed to the support leg 101 via a processing frame 102. The lower end of the mounting plate 105 has a grinding mechanism for grinding the upper inclined surface of the window frame plate 301. Downstream of the grinding mechanism is a laser welding head 104 for welding the closed end position of the window frame plate 301. The transfer mechanism drives the window frame positioning mechanism 300 to move, and the window frame plate 301 on the window frame positioning mechanism 300 moves to the grinding position. The grinding mechanism completes the grinding of the window frame plate 301, and the laser welding head 104 welds the ends of the two window frame plates 301, thus completing the part processing. The mounting plate 105 is also equipped with a camera group 103 at the rear to obtain the welding status of the upper end of the window frame plate 301, so as to carry out quality inspection of the welded products of the window frame plate 301 and ensure the processing quality. The camera group and laser sensor work together to achieve quality inspection. The core principle is as follows: Two industrial-grade high-definition CCD cameras are used in conjunction with a coaxial supplementary lighting module and a dustproof protective shell. When the laser sensor detects that the window frame positioning mechanism carries the welded window frame plate to the quality inspection station, the camera is simultaneously triggered to capture high-speed images of the weld area from both the front and side views. After the acquired images are preprocessed by grayscale conversion, noise filtering, and contrast enhancement, features such as weld width, centerline offset, and defect location are extracted through algorithms such as Canny edge detection and polynomial contour fitting. These features are compared with preset qualified thresholds (such as weld width 2-3mm, offset ≤0.3mm, etc.) to accurately identify defects such as incomplete penetration, porosity, and cracks. Qualified parts flow into the receiving plate, while unqualified products are diverted to the defective product collection tank through a diversion structure. When three consecutive unqualified products are found, the equipment triggers an audible and visual alarm. At the same time, the quality inspection data is automatically stored for traceability. The entire process is non-contact inspection and is deeply integrated with the assembly line process to ensure processing quality and efficiency. The grinding mechanism includes a hanging plate set at the lower end of the mounting plate 105. A grinding motor 107 is fixedly mounted on the hanging plate. A grinding disc 106 is provided at the output end of the grinding motor 107. Grinding layers are provided on both sides of the grinding disc 106. A grinding shell 108 for protection is provided on the outer side of the grinding disc 106. In this way, the grinding disc 106 can be rotated by the grinding motor 107, thereby completing the synchronous grinding of the upper ends of the two window frame plates 301. The support 100 is provided with a receiving mechanism at its end for receiving materials. The receiving mechanism includes a receiving plate 400 for carrying parts. The receiving plate 400 is provided with a leakage grid hole 401 for filtering at its end. The leakage grid hole 401 is provided with a particle collection groove 402 for particulate impurities on its lower side. When the transfer mechanism drives the window frame positioning mechanism 300 to flip, the window frame plate 301 on the window frame positioning mechanism 300 will detach. The impurities remaining on the window frame positioning mechanism 300 will also be collected by the receiving plate 400. The particulate impurities will pass through the leakage grid hole 401 and enter the particle collection groove 402. One end of the particle collection groove 402 is open, so that the particulate impurities can be easily swept out from one side later. The window frame positioning mechanism 300 includes a fixture base plate 322, the bottom of which is connected to the surface of the transfer mechanism. Two symmetrically arranged support inclined plates 302 are provided on the upper end of the fixture base plate. The two support inclined plates 302 form an inverted V-shape, allowing two window frame parts to be placed on the surface of the support inclined plates 302 so that the two window frame parts are vertically positioned. A notch 303 is left between the upper ends of the two support inclined plates 302 to allow space for grinding. The surface of the window frame plate 301 is slidably provided with… A support plate 320 is used to support the bottom of the window frame plate 301. A sliding guide unit is provided between the support plate 320 and the support inclined plate 302. The support plate 320 is provided on both sides for locking the outer side of the window frame plate 301. The segmented locking unit can lock the window frame plate 301 in the grinding position, providing a basis for grinding. In the welding position, the support plate 320 further pushes the window frame plate 301 to slide upward, so that the upper ends of the two window frame plates 301 are closed, providing a basis for welding. The bracket 100 is provided with a stabilizing mechanism that supports the position of the tooling base plate 322. The stabilizing mechanism further limits the position of the tooling base plate 322, so that the upper window frame positioning mechanism 300 can operate stably. The stabilizing mechanism includes T-shaped sleeves 321 symmetrically arranged at the lower end of the tooling base plate 322. The upper end of the bracket 100 is connected to the limiting plate 500 through the stabilizing frame. The limiting plate 500 has pointed inclined surfaces 502 on both sides of its front end, and a guide slope 503 at its tip. Through the guide slope 503 and the pointed inclined surfaces 502, the limiting plate 500 is better inserted into the T-shaped sleeves 321 so that the tooling base plate 322 can obtain horizontal support force. The upper end face and two sides of the limiting plate 500 are distributed with multiple spherical cavities, and ball bearings 501 are fitted in the spherical cavities to replace sliding friction with rolling friction and reduce the frictional wear of the components. Two supporting inclined plates 302 are symmetrically provided with side sealing plates 317 on both sides. The two side sealing plates 317 and the supporting inclined plates 302 form a collection cavity, which facilitates the collection of welding particles. When unloading later, the particles in the collection cavity can also be discharged. The segmented locking unit includes pressing surfaces 305 symmetrically arranged on both sides of the lifting plate 320. Two side sliding rods 312 are provided at the lower end of each pressing surface 305. The side sliding rods 312 are slidably disposed with side sliding holes on the supporting inclined plate 302. The end of the lifting plate 320 is connected to the pressing surface 305 by a second spring 313. A guide inclined surface 315 is provided on the outer side of each pressing surface 305. The surface of the supporting inclined plate 302 is rotatably provided with pressing roller shafts 316 corresponding to the two guide inclined surfaces 315. The clamping surface of the pressing surface 305 is provided with padding blocks for clamping the window frame plate 301. These padding blocks can lock the position of the window frame plate 301, improving the clamping effect. The lower end of the lifting plate 320... A pressure rod 311 is provided at the center position. A pressure wheel 310 is rotatably provided at the end of the pressure rod 311. Top pressure plate groups 600 are provided on both sides of the bracket 100 to push the pressure wheel 310. When the top pressure plate groups 600 push the pressure wheel 310, the lifting plate 320 slides upward along the support inclined plate 302. When sliding, the extrusion roller shaft 316 generates a thrust on the guide inclined surface 315, thereby bringing the two extrusion surfaces 305 closer together so as to lock the position of the window frame plate 301. The extrusion surfaces 305 move synchronously here, thereby completing the centering of the window frame plate 301. In this way, the ends of the two window frame plates 301 can be accurately connected during the clamping process, ensuring processing quality and processing efficiency. The top pressure plate assembly 600 includes a top pressure plate 601 arranged parallel to the bracket 100. The top pressure plate 601 is connected and fixed to the outside of the bracket 100 via a connecting side frame 605. The front end of the top pressure plate 601 is provided with a ramp surface 604 for guiding the pressure roller 310. The surface of the top pressure plate 601 downstream of the ramp surface 604 is provided with a clamping guide surface 603 and a welding guide surface 602. The clamping guide surface 603 and the welding guide surface 602 are connected by a butt joint slope. When the window frame positioning mechanism 300 moves to the grinding position, the window frame plate 301 moves along the ramp surface. 604 slides to the clamping guide surface 603, thereby bringing the two clamping bars 314 closer together and completing the initial clamping of the window frame plate 301. After welding is completed, as the window frame plate 301 and the window frame positioning mechanism 300 continue to move to the welding position, the pressure roller 310 moves to the welding guide surface 602 under the guidance of the transition slope. At this time, the lifting plate 320 drives the window frame plate 301 to slide upward, thereby making the upper ends of the two window frame plates 301 close together. Then, the laser welding head 104 spot welds the end joint position of the window frame plate 301 to complete the welding process. A laser sensor for detecting the position of the window frame positioning mechanism 300 is provided below the mounting plate 105, which makes it easier to control the determination of the processing position of the window frame plate 301. The pad block includes multiple elastic grooves 318 formed on the inner side of the extrusion surface 305. A floating clamping block 306 is slidably disposed in each elastic groove 318. The clamping surface of the floating clamping block 306 is provided with clamping protrusions 304. The inner wall of the elastic groove 318 and the floating clamping block 306 are connected by an elastic post 319. During the clamping process, the floating clamping block 306 can be retracted into the elastic groove 318. This storage method can give the floating clamping block 306 a certain avoidance basis and avoid the problem of over-clamping. The outer side of the extrusion roller shaft 316 is provided with a rubber layer to reduce wear between the extrusion roller shaft 316 and the guide slope 315. The sliding guide unit includes guide posts 309 symmetrically arranged on both sides of the lower end of the support plate 320. The guide posts 309 are slidably arranged with the guide sleeves 308 on the surface of the support inclined plate 302. The support plate 320 and the guide sleeves 308 are connected and fixed by a first spring 307. In the initial state, the window frame is in contact with the surface of the support plate 320 under the action of gravity. When the first spring 307 is reset, the support inclined plate 302 will always be in the lowest position. At this time, the window frame plate 301 is in a free state, which is convenient for loading and unloading. The transfer mechanism includes a transmission belt 201 rotatably mounted at both ends of the bracket 100. The two transmission belts 201 are connected by a transmission belt 202. One of the transmission belts 201 is connected to a transmission motor 200 for driving its rotation. The transmission motor 200 drives the transmission belt 201 to rotate, and the transmission belt 201 drives the transmission belt 202 to rotate, thereby driving the window frame positioning mechanism 300 to circulate, so as to circulate the fixed window frame plate 301 to improve processing efficiency.

[0010] Working principle: During actual processing, the window frame plate 301 to be processed is placed on the surface of two supporting inclined plates 302. Initially, the window frame plate 301 is in a free state. The transmission motor 200 drives the transmission belt 201 to rotate, and the transmission belt 201 drives the drive belt 202 to rotate, thereby driving the window frame positioning mechanism 300 to circulate. When the window frame positioning mechanism 300 moves to the grinding position, the top pressure plate group 600 pushes the pressure roller 310, and the lifting plate 320 slides upward along the supporting inclined plate 302. When sliding, the extrusion roller shaft 316 generates a thrust on the guide inclined surface 315, thereby bringing the two extrusion surfaces 305 closer together to lock the position of the window frame plate 301. The extrusion surfaces 305 move synchronously here, thereby completing the centering of the window frame plate 301. In this way, the ends of the two window frame plates 301 can be accurately joined during the clamping process, ensuring processing quality and processing efficiency. After being centered and clamped, the window frame plate 301 is moved to the grinding position to complete the grinding operation. After the grinding operation, the window frame plate 301 continues to move. At this time, under the guidance of the transition slope, the pressure roller 310 moves to the welding guide surface 602. At this time, the lifting plate 320 drives the window frame plate 301 to slide upward, so that the upper ends of the two window frame plates 301 are joined and closed. Then, the laser welding head 104 is used to spot weld the joint position of the end of the window frame plate 301 to complete the welding process.

[0011] The welding method here is a flow-line processing. When loading the material, simply place the window frame plate 301 in the predetermined position without precise fixing. Then, the self-locking gravity of the window frame plate 301 is used to complete the longitudinal adjustment. Then, the horizontal centering is completed by the synchronous clamping on both sides, completing the pre-welding alignment operation. Finally, the window frame plate 301 is moved synchronously to automatically fit the upper inclined surface, and then welding is carried out, which greatly improves the processing efficiency. Under the action of the transfer mechanism, the window frame positioning mechanism 300 and the top pressure plate assembly 600 are misaligned. At this time, the window frame positioning mechanism 300 will release its grip on the window frame plate 301. As the window frame positioning mechanism 300 rotates to the bottom of the transfer mechanism, the window frame plate 301 on the window frame positioning mechanism 300 will be collected by the receiving plate 400. The residual particulate impurities on the window frame positioning mechanism 300 will slide into the receiving plate 400 and finally be collected at the particulate collection groove 402.

[0012] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
