DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0027] like Figure 1 , Figure 2 and Figure 3 FIG. 1 is a schematic diagram of the overall structure of a cutting device for aluminum alloy door and window profiles provided by an embodiment of the present invention, wherein the device comprises:

[0028] A feeding frame 1, on which a feeding assembly is installed, the feeding assembly includes a loading plate 3, the bottom of the loading plate 3 is fixedly connected to an auxiliary bracket through a tension sensor 13, two groups of short shafts are fixedly arranged on the auxiliary bracket, rollers are rotatably installed at the ends of the short shafts, an airbag 10 is provided on the roller jacket, a group of magnetic rings are slidably arranged on the short shafts, an electromagnet is fixedly installed on the auxiliary bracket, the electromagnet is coaxially arranged with the magnetic ring, a group of first telescopic rods 7 are fixedly installed on the auxiliary bracket, the telescopic end of the first telescopic rod 7 is fixedly connected to a first bracket 8, a plurality of groups of first clamping wheels 9 are rotatably arranged on the first bracket 8, and the first clamping wheels 9 are driven by a conveying motor;

[0029] A cutting frame 2, in which a distance sensor, a multi-angle cutting component and a multi-functional conveying mechanism are installed, and the multi-functional conveying mechanism is fixedly installed in the cutting frame 2 and is used to convey door and window profiles and flip door and window profiles;

[0030] An image acquisition component is fixedly mounted on the end of the cutting frame 2 and is used to identify the model and placement angle of the door and window profiles.

[0031] In the present embodiment, the material cutting calculation process of the door and window profiles is usually completed by software. The number and size of the cut profiles to be used this time are input into the material cutting software. Then the material cutting software will automatically query the inventory and generate a cutting plan for each complete material based on the inventory. For example, a 6-meter door and window profile is cut into three 2-meter-long profiles. The material cutting plan is automatically calculated. In the material cutting plan, the cutting plan, material quantity and model of each profile are recorded. When the material cutting plan is obtained, cutting can be carried out. The operator takes the material from the warehouse according to the material cutting plan, places the taken-out profile to be processed on the loading plate 3, and the profile to be processed is laid flat on the loading plate 3. When cutting starts, the electromagnet is energized to generate a magnetic field by using the electromagnet. The electromagnet repels the magnetic ring, and the magnetic ring approaches the airbag 10 along the short axis. After the airbag 10 is squeezed, its diameter increases, and the profile to be processed is lifted up. The first telescopic rod 7 is pressed down so that the first clamping wheel 9 is against the profile to be processed, and the conveying motor drives the first clamping wheel 9 to move upward. The clamping wheel 9 rotates, and the first clamping wheel 9 drives the profile to be processed to move to the side close to the cutting frame 2, so that it enters the space in the cutting frame 2. At this time, the entire profile to be processed is completely lifted, and the weight of the entire profile to be processed can be detected by the tension sensor 13. After the profile to be processed is input into the multi-functional conveying mechanism, the image acquisition component is used to acquire an image of the profile to be processed, and the profile model of the profile to be processed is determined by identifying the cross-section of the profile to be processed. The linear density of the profile to be processed can be determined according to the profile model, and the length of the current profile to be processed can be calculated according to the linear density and the total amount. The cutting length and angle of the profile to be processed of the current length can be determined by querying the blanking plan, and then the multi-functional conveying mechanism is used to control the feeding length, and the multi-angle cutting component is used for cutting. The distance sensor can detect whether the profile to be processed enters the cutting frame 2, so as to determine the feeding amount according to the conveying speed of the multi-functional conveying mechanism to achieve control of the cutting length;

[0032] In this embodiment, the process of profile recognition by the image acquisition component is as follows:

[0033] The image to be identified is acquired by the image acquisition component, and is converted into a grayscale image. The grayscale image is then converted into a line graph using the Hough transform. The cross-sectional line graph of the profile to be processed can be extracted from the line graph, and a database is queried based on the cross-sectional line graph to determine the profile model of the profile to be processed. According to the angle of the cross section of the profile, it can be determined whether the profile to be processed is in a horizontal state.

[0034] like Figure 1 , Figure 2 and Figure 3As shown, as a preferred embodiment of the present invention, the feeding assembly includes a sliding seat 6, a first screw 4 is rotatably arranged on the feeding frame 1, a guide rod 5 is fixedly arranged on the feeding frame 1, the guide rod 5 is arranged parallel to the first screw 4, the sliding seat 6 is slidably arranged on the guide rod 5, a threaded hole is arranged on the sliding seat 6, the sliding seat 6 is connected to the first screw 4 by threads, and the first screw 4 is driven by a lifting motor.

[0035] In this embodiment, when loading, the lifting motor drives the first screw 4 to rotate, and the first screw 4 will drive the sliding seat 6 to slide downward. The loading plate 3 is fixedly connected to the sliding seat 6, so the loading plate 3 will drop to the lowest height. At this time, the operator can easily lay the profile to be processed on the loading plate 3.

[0036] like Figure 1 , Figure 4 and Figure 5 As shown, as a preferred embodiment of the present invention, the multi-angle cutting assembly includes a worm gear 12, which is rotatably mounted on the cutting frame 2, a suspension bracket is fixedly mounted on the bottom of the worm gear 12, a cutting motor is fixedly mounted on the suspension bracket, a saw blade 26 is mounted on the cutting motor, a rotating motor is fixedly mounted on the cutting frame 2, a worm is fixedly mounted on the output shaft of the rotating motor, and the worm is meshed with the worm gear 12.

[0037] In this embodiment, during the processing of door and window profiles, some profiles need to be cut at a 45-degree angle, that is, inclined cutting. Different doors and windows have different processing angles. In order to complete multi-angle cutting of the profiles to be processed, the cutting motor can be started, and the cutting motor drives the saw blade 26 to rotate, thereby realizing the cutting of the profiles to be processed. If the angle needs to be adjusted, the rotating motor is started, and the rotating motor drives the worm to rotate, and the worm drives the worm wheel 12 to rotate, and the worm wheel 12 drives the saw blade 26 to rotate, thereby realizing multi-angle cutting.

[0038] like Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, as a preferred embodiment of the present invention, the multifunctional conveying mechanism includes a plurality of conveying components, which are installed in pairs on the inner wall of the cutting frame 2. The conveying components include two sets of hollow shafts 27, two sets of first gears 19 and two sets of second gears 20. The two sets of hollow shafts 27 are fixedly installed on the cutting frame 2. A slide groove is provided on the hollow shaft 27, and a slip ring 29 is slidably provided on the slide groove. A second screw 28 is provided in the hollow shaft 27, and the second screw 28 is connected to the slip ring 29 by threads. The second screw 28 is driven by a second motor 16 fixedly installed on the cutting frame 2. The two sets of second gears 20 are rotatably installed on the outer edges of the hollow shaft 27, and the two sets of second gears 20 are rotatably installed on the outer edges of the hollow shaft 27. On the cutting frame 2, two groups of first gears 19 are respectively meshed with two groups of second gears 20, and the two groups of second gears 20 are respectively fixedly installed with a third pulley 25 and a fourth pulley, and the third pulley 25 and the fourth pulley are connected by a first transmission belt 21. The two groups of first gears 19 are respectively fixedly installed with a first pulley 23 and a second pulley 24, and the first pulley 23 and the second pulley 24 are connected by a second transmission belt 22. Multiple groups of support rods 31 are hinged on the first gear 19, and multiple groups of support arms 30 are hinged on the slip ring 29. The end of the support arm 30 is hinged to the support rod 31. A second telescopic rod 11 is fixedly installed on the cutting frame 2, and a second clamping wheel 18 is rotatably installed on the end of the second telescopic rod 11.

[0039] In this embodiment, the conveying components installed on the same side of the cutting frame 2 move synchronously. After the profile to be processed enters the inner side of the cutting frame 2, the state of the profile to be processed is identified by the image acquisition component to determine its model, cutting length and horizontal state. When the profile is not in a horizontal state, according to the current horizontal state, such as the angle between the bottom surface of the profile and the horizontal plane, if the profile to be processed tilts to the right, the support rod 31 in the right conveying component is controlled to open, so that the height of the profile to be processed on this side will be raised, and the bottom surface of the profile to be processed will be aligned with the horizontal plane. The horizontal planes coincide. If the profile to be processed needs to be turned over in this embodiment, any side of the inner wall of the cutting frame 2 can be defined as the left side, and its opposite side is defined as the right side. Only the support rod 31 on the right side is provided with an anti-slip sleeve 32, and the anti-slip sleeve 32 is one-way anti-slip, that is, the friction force when sliding from right to left along the anti-slip sleeve 32 is much greater than the friction force when sliding from left to right. Then the support rod 31 on the right side is opened synchronously, and the support rod 31 on the left side is contracted synchronously. Then, under the toggle of the support rod 31 on the right side, the profile to be processed will gradually begin to turn over, and then the left side The support rods 31 on the side and right side return to the initial state synchronously, and the above process is repeated to realize the flipping of the profile to be processed. When the support rod 31 is controlled to open or retract, the second motor 16 is started, and the second motor 16 is used to drive the second screw 28 to rotate. The second screw 28 drives the slip ring 29 to slide linearly along the hollow shaft 27. When the slip ring 29 slides to the side away from the second motor 16, the slip ring 29 will drive the support rod 31 to open through the support arm 30. On the contrary, when the slip ring 29 slides to the side close to the second motor 16, the slip ring 29 will The support arm 30 drives the support rod 31 to retract. When the feeding needs to be controlled, the material first enters the top of the conveying assembly. Then, after the adjustment is completed, the material to be processed is in a horizontal state or a specific flip angle, the second telescopic rod 11 extends, and the second telescopic rod 11 drives the second clamping wheel 18 to abut against the profile to be processed. The second clamping wheel 18 is driven by the feeding motor, and the feeding motor drives the profile to be processed to move forward through the second clamping wheel 18 until the distance sensor detects the profile to be processed. At this time, the feed amount of the profile to be processed is equal to , where V is the linear speed of the second clamping wheel 18, and t is the running time of the feeding motor. During this process, the third motor 17 rotates synchronously, thereby driving the profile to be processed to feed. After the feeding is completed, cutting begins.

[0041] In this embodiment, after the cutting is completed, when the cut material needs to be separated, the support rod 31 on the left side is synchronously contracted and the support rod 31 on the right side is synchronously opened, and the material slides to the right side to the conveyor belt 14. Conversely, the support rod 31 on the right side is synchronously contracted and the support rod 31 on the left side is synchronously opened, and the material slides to the left side to the conveyor belt 14.
