Description

Technical Field

[0001] This invention relates to the field of flat tube processing technology, specifically to an automated processing line for finned flat tubes. Background Technology

[0002] Finned flat tubes have a flat cross-section, which can increase the heat exchange area per unit volume. Finned flat tubes usually require cutting and grinding steps during processing.

[0003] In related technologies, such as the heat exchanger flat tube cutting device with announcement number CN102009349B, there is a base, a milling mechanism that can slide laterally along the base, and a punching mechanism that can slide longitudinally along the base. The flat tubes that are conveyed longitudinally along the base are inserted into the milling mechanism and the punching mechanism. The milling mechanism is provided with a milling cutter to mill the flat tube and form a milling cut, and the punching mechanism is provided with a punch that can detect the position of the milling cut and punch.

[0004] Flat tubes are often made of materials such as aluminum, copper, low carbon steel and some stainless steel. Flat tubes themselves have good plasticity and toughness, and burrs are easily formed on the cutting surface. Therefore, it is necessary to remove the burrs by grinding. However, during grinding, the burrs on the cutting end face and the outer surface of the flat tube need to be treated in batches. It is difficult to complete the overall grinding of the flat tube surface in one go, resulting in low efficiency of the cutting and deburring assembly line operation. Summary of the Invention

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1-15 As shown, an embodiment of the present invention provides an automated processing line for finned flat tubes, comprising: refer to Figure 1 , Figure 3 Support component 1 is used to provide installation position and support force; support component 1 includes base plate 102, support frame 101 is fixedly connected to base plate 102, and controller 103 is fixedly installed on support frame 101. The support frame 101 can be made of square tubing welded together, and the controller 103 is used to provide control functions.

[0022] refer to Figure 2 , Figure 4 The feeding assembly 2 is located at one end of the support assembly 1 and is used to transport flat tube workpieces. The feeding assembly 2 includes a feeding frame 201 fixedly installed on the support frame 101, a feeding motor 202 fixedly installed on the feeding frame 201, and two feeding wheels 203 installed on the feeding frame 201. The output end of the feeding motor 202 is fixedly connected to one of the feeding wheels 203. During the feeding operation, one end of the flat tube workpiece is first placed between the two feeding wheels 203. The feeding wheels 203 can provide limiting forces in the up-down and left-right directions on the flat tube workpiece. The feeding motor 202 works under the action of the external power supply and controller 103, driving one of the feeding wheels 203 to rotate. The feeding wheel 203 can drive the flat tube workpiece to move, realizing the function of automatic feeding.

[0023] refer to Figure 1 , Figure 15 The moving component 11 is mounted on the support component 1 and is used to provide a moving function. The moving component 11 includes a moving rail 1102 and a moving push rod 1101 fixedly mounted on the base plate 102. The telescopic end of the moving push rod 1101 is fixedly connected to a moving frame 1103. The moving frame 1103 is slidably engaged with the moving rail 1102. A support wheel set 1106 is fixedly mounted in the middle of the moving frame 1103. A support plate 1104 is provided on the outer side of the support wheel set 1106. A side column 1105 is fixedly connected to the center of the support plate 1104. The support plate 1104 is rotatably engaged with the moving frame 1103. A cutting gap is reserved between the two support wheel sets 1106. An infrared distance sensor 1107 is fixedly mounted on the side of the moving frame 1103. To mill and cut a flat tube workpiece of the appropriate length, adjustments can be made through a moving operation. Specifically, the moving push rod 1101 operates under the action of an external power supply and controller 103, driving the moving frame 1103 to move on the moving rail 1102. As the moving frame 1103 moves, the infrared distance sensor 1107 moves along with it. The infrared distance sensor 1107 detects the real-time distance between the cutting gap of the moving rail 1102 and the end face of the support frame 101, and displays it on the display screen of the controller 103. The obtained value, plus the known value between the positioning plate 1002 and the end face of the support frame 101, gives the target length of the flat tube workpiece to be cut. The height of the support plate 1104 is the same as the height of the support wheel assembly 1106, which can provide support for the flat tube workpiece; the outer circular surface of the side column 1105 can provide a limiting force for the outer surface of the flat tube workpiece, ensuring the stability of the flat tube workpiece and providing the necessary limiting force for subsequent clamping operations.

[0024] refer to Figure 1 , Figure 5 The clamping assembly 3 is disposed on the moving part of the moving assembly 11 and is used to provide clamping force. The clamping assembly 3 includes a clamping frame 301 fixedly installed on the moving frame 1103, a clamping cylinder 302 fixedly installed on the clamping frame 301, and a clamping plate 303 fixedly connected to the output end of the clamping cylinder 302. During clamping operations, the clamping cylinder 302 works under the action of the external air source and controller 103, driving the clamping plate 303 to move downward, which can cooperate with the support wheel set 1106 to clamp the flat tube workpiece, avoid the flat tube workpiece from shaking during milling, and improve the quality of milling and cutting.

[0025] refer to Figure 1 , Figure 2 , Figure 10 Rotating component 7 is disposed on the moving part of moving component 11 and is used to provide rotation function; rotating component 7 includes a rotating seat 701 fixedly installed on moving frame 1103, a ring tooth 702 fixedly connected to the upper part of rotating seat 701, a ring rail 703 fixedly connected to the end face of ring tooth 702, a slide block 704 slidably connected to ring rail 703, a brakeable motor 706 fixedly installed on slide block 704, a drive gear 705 fixedly connected to the output end of brakeable motor 706, and the drive gear 705 meshes with ring tooth 702. To facilitate the milling and grinding of both sides of the flat tube workpiece, a rotational operation can be performed. Specifically, the brakeable motor 706 operates under the control of an external power supply and controller 103, driving the drive gear 705 to rotate. The drive gear 705 rotates on the ring gear 702, thereby driving the slide 704 and the adjacent component 4 to rotate, ensuring that the milling component 5 and the grinding component 6 can work along a circular trajectory. The brakeable motor 706 itself has a braking function, so it can brake at various angles to ensure the stability of the adjacent component 4. The rotation direction of the rotating component 7 is not limited. It can be selected to always rotate in one direction, such as clockwise, or to rotate back and forth, such as first clockwise and then counterclockwise.

[0026] refer to Figure 1 , Figure 6 , Figure 10 The proximity component 4 is located on the rotating part of the rotating component 7 and is used to provide a mutual proximity function. The proximity component 4 includes a central plate 405 fixedly mounted on the slide block 704. A proximity housing 401 is fixedly connected to the central plate 405. A proximity motor 402 is fixedly mounted at the end of the proximity housing 401. A bidirectional lead screw 404 is fixedly connected to the output end of the proximity motor 402. A proximity block 403 is threadedly connected to the bidirectional lead screw 404. The proximity block 403 slides with the proximity housing 401. A moving channel 406 is provided at the lower part of the proximity housing 401. In order to change the distance between the milling component 5 and the grinding component 6, a close-up operation can be performed. Specifically, the close-up motor 402 works under the action of the external power supply and the controller 103, which drives the bidirectional lead screw 404 to rotate. The bidirectional lead screw 404 can drive the two close-up blocks 403 to move closer to each other or further away from each other, thereby driving the milling component 5 and the grinding component 6 on the two close-up blocks 403 to move closer to each other or further away from each other.

[0027] refer to Figure 1 , Figure 7 Milling assembly 5, which is located on one of the moving parts near assembly 4, is used to provide milling function; milling assembly 5 includes a milling housing 501 fixedly mounted on one side near block 403, a milling motor 502 fixedly mounted on the milling housing 501, a circular end mill 503 fixedly connected to the output end of the milling motor 502, the circular end mill 503 being located inside the milling housing 501, and a detection block 504 fixedly connected to the milling housing 501; During milling operations, the milling motor 502 operates under the control of the external power supply and controller 103, driving the circular milling cutter 503 to rotate. The rotation of the circular milling cutter 503 enables milling and cutting of flat tube workpieces.

[0028] refer to Figure 1 , Figure 8 , Figure 9 Grinding assembly 6, located on another moving part near assembly 4, provides grinding functionality. Grinding assembly 6 includes a grinding housing 601 fixedly mounted on the other side near block 403. A grinding motor 602 is fixedly mounted on the grinding housing 601. A central disk 603 is fixedly connected to the output end of the grinding motor 602. A grinding arc strip 604 is fixedly mounted on the circumferential surface of the central disk 603. A radial groove 606 is provided on the central disk 603, and a radial... A limiting strip 611 is fixedly connected inside the radial groove 606 and located outside the radial block 608. A connecting block 609 is fixedly connected to the outer end of the radial block 608. A movable grinding strip 610 is fixedly connected to the other end of the connecting block 609 away from the radial block 608. A tension spring 607 is fixedly connected between the inner side of the radial block 608 and the center plate 603. An infrared distance sensor 605 is fixedly connected to the grinding shell 601. The radius of the center plate 603 is smaller than the radius of the circular milling cutter 503. During the grinding and milling end face operation, the grinding motor 602 works under the action of the external power supply and controller 103, driving the center disk 603 to rotate, which in turn drives the grinding arc 604 and the moving grinding strip 610 to rotate. The outer surfaces of the grinding arc 604 and the moving grinding strip 610 come into contact with the milling surface of the flat tube workpiece, thus realizing the function of grinding and milling the end face. Since the center disc 603 is circular in shape, and the circular milling cutter 503 is also circular, in order to avoid collision between the circular milling cutter 503 and the center disc 603 when they are close together, the radius of the center disc 603 should be smaller than the radius of the circular milling cutter 503. This ensures that the circular milling cutter 503 can completely mill and cut off the flat tube workpiece, and that the circular milling cutter 503 and the center disc 603 will not collide at their closest extreme positions. Because the radius of the center disc 603 is smaller than the radius of the circular milling cutter 503, under the same path conditions, the center disc 603 cannot be completely ground to the milled end face. At this point, the second state is switched. In this state, the grinding motor 602 needs to drive the central disk 603 to rotate at high speed, so that the radial block 608, connecting block 609, and moving grinding strip 610 as a whole generate sufficient centrifugal force when rotating. This centrifugal force is greater than the tension of the tension spring 607. Therefore, the radial block 608, connecting block 609, and moving grinding strip 610 as a whole will slide in the radial groove 606. At the same time, under the action of the limiting strip 611, the radial block 608 will only move to the limiting strip 611, and the moving grinding strip 610 will not move outward indefinitely. Therefore, the entire milled end face can be completely ground. In order to provide sufficient position for the moving grinding strip 610 to grind, the two approaching blocks 403 can be moved away from each other by means of the approaching component 4, thereby driving the milling component 5 and the grinding component 6 to move away from each other. In order to accurately control the distance, the infrared distance sensor 605 can detect the real-time distance between itself and the detection block 504 and transmit the data to the controller 103, thereby meeting the requirement of accurately controlling the distance between the two milling components 5 and the grinding component 6; the positions of the detection block 504 and the infrared distance sensor 605 correspond to each other.

[0029] refer to Figure 1 , Figure 11 , Figure 12 Polishing assembly 8 is located on the moving part of moving assembly 11 and is situated on the discharge side of milling assembly 5. It is used to provide polishing function for the outer surface of flat tube. Polishing assembly 8 includes a polishing frame 801 fixedly mounted on moving frame 1103. A polishing motor 802 is fixedly mounted on the side of polishing frame 801. Two polishing wire rollers 803 are rotatably mounted on polishing frame 801. The output end of polishing motor 802 is fixedly connected to the lower polishing wire roller 803. A drive pulley 804 is fixedly connected to the lower polishing wire roller 803, and a driven pulley 806 is fixedly connected to the upper polishing wire roller 803. A synchronous belt 805 is provided between the drive pulley 804 and the driven pulley 806. The polishing wire roller 803 is provided with a central columnar part 8031, a gradient part 8032, and a side columnar part 8033 in sequence from the middle to both ends. A connecting shaft 8034 is fixedly connected inside the polishing wire roller 803. During polishing, the polishing motor 802 operates under the power of the external power supply and the controller 103, driving the lower polishing wire roller 803 to rotate. The lower polishing wire roller 803 drives the drive pulley 804 to rotate. The drive pulley 804 drives the driven pulley 806 to rotate via the synchronous belt 805. The driven pulley 806 drives the upper polishing wire roller 803 to rotate, thus realizing the function of synchronously driving the upper and lower polishing wire rollers 803 to rotate. The rotation of the polishing wire roller 803 can perform grinding and polishing operations on the outer surface of the flat tube workpiece. The polishing wire roller 803 is specially designed with specially cut polishing bristles. The bristles cut at the central columnar part 8031 ​​can contact the straight outer surface of the flat tube workpiece, and the bristles cut at the gradient part 8032 can contact the arc outer surface of the flat tube workpiece. The bristles cut at the side columnar part 8033 have the same length as the bristles at the maximum radius of the gradient part 8032, which can ensure that the bristles at the gradient part 8032 are not too scattered.

[0030] refer to Figure 1 , Figure 2 , Figure 13 The guide component 9 is located at the other end of the support component 1 and is used to guide the flat tube workpiece. The guide component 9 includes a guide frame 901 fixedly installed on the support frame 101, and a guide wheel 902 is rotatably connected to the guide frame 901. During the guiding operation, the guide wheel 902 can provide limiting forces in four directions—up, down, left, and right—to the flat tube workpiece, ensuring its stability and allowing for smooth material discharge.

[0031] refer to Figure 1 , Figure 2 , Figure 14 Positioning component 10 is located at the discharge end of support component 1 and is used to position flat tube workpiece; positioning component 10 includes positioning cylinder 1001 fixedly installed on support frame 101, and positioning plate 1002 is fixedly connected to the output end of positioning cylinder 1001. During positioning operations, the positioning cylinder 1001 works under the action of the external air source and the controller 103, driving the positioning plate 1002 to move upward. The positioning plate 1002 can block the end face of the flat tube workpiece, thereby realizing the positioning function. When the positioning plate 1002 is reset, the flat tube workpiece is no longer restricted by the positioning plate 1002 and can be discharged smoothly. The positioning plate 1002 is L-shaped, which can reduce the space occupied below the positioning plate 1002 and improve the overall compactness.

[0032] Working principle: One end of the flat tube workpiece is first placed between two feeding wheels 203. The feeding wheels 203 can provide limiting force in the up and down and left and right directions on the flat tube workpiece. The feeding motor 202 works and drives one of the feeding wheels 203 to rotate. The feeding wheel 203 can drive the flat tube workpiece to move, realizing the function of automatic feeding. When the positioning cylinder 1001 is working, it drives the positioning plate 1002 to move upward. The positioning plate 1002 can block the end face of the flat tube workpiece to achieve the positioning function. At this time, the feeding stops. The movable push rod 1101 operates, driving the movable frame 1103 to move on the movable rail 1102. As the movable frame 1103 moves, the infrared distance sensor 1107 moves accordingly. The infrared distance sensor 1107 detects the real-time distance between the cutting gap of the movable rail 1102 and the end face of the support frame 101, and displays it on the display screen of the controller 103. The obtained value, plus the known value between the positioning plate 1002 and the end face of the support frame 101, can give the target length of the flat tube workpiece to be cut. When the clamping cylinder 302 is working, it drives the clamping plate 303 to move down, which can cooperate with the support wheel set 1106 to clamp the flat tube workpiece. The milling motor 502 operates, driving the circular end mill 503 to rotate; When the motor 402 is working, it drives the bidirectional lead screw 404 to rotate, and the bidirectional lead screw 404 can drive the two proximity blocks 403 to move closer to each other. At the same time, the brakeable motor 706 works, driving the drive gear 705 to rotate. The drive gear 705 rotates on the ring gear 702, thereby driving the slide 704 and the part close to component 4 to rotate, ensuring that the milling component 5 and the grinding component 6 can work in a circular trajectory, thereby realizing the milling and cutting function. When grinding and milling the end face, the grinding motor 602 works, driving the center disk 603 to rotate, which in turn drives the grinding arc 604 and the moving grinding strip 610 to rotate. The outer surfaces of the grinding arc 604 and the moving grinding strip 610 come into contact with the milling surface of the flat tube workpiece, thus realizing the function of grinding and milling the end face. In order to provide sufficient space for the moving grinding bar 610 to grind, the two proximity blocks 403 can be moved away from each other by the proximity component 4, thereby causing the milling component 5 and the grinding component 6 to move away from each other by a certain distance. In order to accurately control the distance between the two milling components 5 and the grinding component 6, the infrared distance sensor 605 can detect the real-time distance between itself and the detection block 504 and transmit the data to the controller 103, thereby meeting the requirement of accurately controlling the distance between the two milling components 5 and the grinding component 6. The grinding motor 602 needs to drive the central disk 603 to rotate at high speed, so that the radial block 608, connecting block 609, and moving grinding strip 610 as a whole generate sufficient centrifugal force when rotating. This centrifugal force is greater than the tension of the tension spring 607. Therefore, the radial block 608, connecting block 609, and moving grinding strip 610 as a whole will slide in the radial groove 606. At the same time, under the action of the limiting strip 611, the radial block 608 will only move to the limiting strip 611, and the moving grinding strip 610 will not move outward indefinitely. Therefore, the entire milled end face can be completely ground.
