Description

Technical Field

[0001] This invention relates to the field of high-frequency welding technology, and in particular to a high-frequency welding device and welding method for aluminum heat exchanger components. Background Technology

[0002] High-frequency welding machines convert low-frequency AC power input from the power grid into high-frequency AC power through electronic circuits. The high-frequency current flows to a specially designed induction coil, generating a strong magnetic flux with instantaneous polarity changes within the coil. When a metal workpiece is placed in the magnetic field of the coil, eddy currents are generated inside, causing the workpiece's temperature to rise rapidly through the Joule heating effect, achieving non-contact and efficient heating, and ultimately completing processes such as welding or heat treatment.

[0003] When welding aluminum heat exchanger components, especially the pipe joints, using a high-frequency welding machine can improve the efficiency of welding aluminum heat exchanger pipe joint components. This involves butt-jointing the components and wrapping the weld joint with a coil, and then directly attaching an induction coil to the pipe joint for non-contact, high-efficiency heating to complete the welding of the aluminum heat exchanger pipe joints.

[0004] However, when welding the nozzle components of aluminum heat exchangers, a conveyor belt is usually used to transport the aluminum heat exchanger. Then, a vision recognition system and a control system are used to identify and position the aluminum heat exchanger. Once the aluminum heat exchanger is transported to the welding area, the transport stops, and the induction coil is driven by a drive mechanism to descend and perform high-frequency welding on the aluminum heat exchanger nozzle components. However, the identification and positioning of the aluminum heat exchanger by the vision recognition system and control system can have identification errors, which can lead to unqualified welding of the aluminum heat exchanger nozzle components, or even collisions between the induction coils, resulting in certain defects.

[0049] A connecting collar and a fixing block are provided, wherein the connecting collar is slidably sleeved on the outside of the first support column, and the fixing block is fixedly connected between the connecting collar and the drive sleeve;

[0054] Another objective of this invention is to provide a high-frequency welding method for aluminum heat exchanger components, comprising the following specific steps:

[0055] Step 1: When performing high-frequency welding on aluminum heat exchanger components, the drive assembly first moves the heating coil to the processing area. At this time, the drive assembly drives the drive sleeve to descend. The drive sleeve pushes the shaft down through the second spring, causing the shaft to engage with the bottom of the outer wall of the locking block and lock the positioning plate. When the conveyor belt moves the aluminum heat exchanger component to the pressing induction block, the second sensor feeds back a signal that the aluminum heat exchanger component has moved to the processing area, and at the same time, the conveyor belt stops conveying the aluminum heat exchanger component.

[0056] Step 2: After the aluminum heat exchanger component moves to the processing area, the drive assembly moves the heating coil to the processing area, so that the heating coil is sleeved on the tube opening of the aluminum heat exchanger component for high-frequency welding, and the heating coil performs high-frequency welding on the tube opening of the aluminum heat exchanger component.

[0057] Step 3: After the high-frequency welding at the nozzle of the aluminum heat exchanger component is completed, the drive assembly moves the heating coil from the processing area to the storage area. The drive assembly also moves the drive sleeve upward. First, the second spring extends and resets until the limiting block at the top of the shaft is in contact with the fixed collar. The drive sleeve then moves the shaft upward through the fixed collar and the limiting block, causing the shaft to move the locking block into the storage groove. The locking block no longer engages with the installation sleeve. The conveyor belt starts to transport the aluminum heat exchanger component. The aluminum heat exchanger component pushes the positioning plate to rotate until the aluminum heat exchanger component is discharged. Under the action of the first spring, the positioning plate rotates and resets, allowing for subsequent high-frequency welding of the aluminum heat exchanger component.

[0058] The technical effects and advantages of this invention are as follows:

[0059] (1) The present invention utilizes the cooperative use of a conveyor belt, an integrated support, a heating coil, a drive assembly, and a positioning assembly. The positioning assembly can position the aluminum heat exchanger components conveyed on the conveyor belt and provide feedback on the conveying of the aluminum heat exchanger components to the high-frequency welding area. This allows the drive assembly to drive the heating coil to descend, enabling the heating coil to perform high-frequency welding on the aluminum heat exchanger components.

[0060] (2) The present invention utilizes the combined use of a heating coil, a driving component, a positioning component, and a linkage component. The driving component can drive the heating coil to move to the processing area, the waiting area, and the storage area. When the heating coil is in the processing area or the waiting area, the driving component can lock and limit the positioning component through the linkage component, thereby preventing the aluminum heat exchanger component from moving directly and causing collision damage to the heating coil. When the heating coil moves to the storage area, the driving component releases the limitation of the positioning component through the linkage component, so that the aluminum heat exchanger component can push the positioning component to move and discharge the aluminum heat exchanger component.

Detailed Implementation

[0071] 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.

[0072] This invention provides, for example Figures 1-8 The image shows a high-frequency welding device for aluminum heat exchanger components.

[0073] Example 1: Includes a supporting housing 1, an integrated bracket 3, a heating coil 4, a drive assembly 5, a positioning assembly 6, and a linkage assembly 7. A conveyor belt 2 for transporting aluminum heat exchanger components is mounted on the top of the supporting housing 1. The integrated bracket 3 is mounted on the supporting housing 1 and guides the aluminum heat exchanger components. The drive assembly 5 is mounted on the integrated bracket 3. The heating coil 4 is driven and mounted at the output end of the drive assembly 5. The heating coil 4 is powered by a high-frequency generator, which integrates a control terminal and a vision recognition system. Both the control terminal and the vision recognition system are existing technologies and will not be described in detail here. The drive assembly 5 moves the heating coil 4 up and down to the processing area, the waiting area, and the storage area. When the heating coil 4 is in the waiting area or the storage area, it does not contact the aluminum heat exchanger components. The aluminum heat exchanger can pass through the bottom of the heating coil 4, which is located in the processing area and the storage area. The positioning component 6 is installed on the integrated bracket 3. The positioning component 6 is used to limit and restrict the aluminum heat exchanger components. The linkage component 7 is set on the integrated bracket 3. The drive component 5 drives the heating coil 4 to move to the processing area and the processing area, so that the linkage component 7 locks and limits the positioning component 6. The drive component 5 drives the heating coil 4 to move to the storage area, so that the linkage component 7 unlocks the positioning component 6. Thus, when the heating coil 4 is in the processing area and the processing area, the positioning component 6 is in a locked state, so that the positioning component 6 can be in a stable state to limit and restrict the aluminum heat exchanger. When the heating coil 4 is in the storage area, the linkage component 7 can unlock the positioning component 6, so that the aluminum heat exchanger can pass through the positioning component 6 and be discharged.

[0074] Furthermore, the integrated bracket 3 includes a first support column 31, a second support column 32, a first fixing member 33, a bearing rod 34, and a second fixing member 35. The first support column 31 and the second support column 32 are both fixedly installed on the side of the bearing housing 1. There are two of each of the first support column 31 and the second support column 32. The positioning component 6 and the linkage component 7 are both installed on the first support column 31. The bearing rod 34 is fixedly installed on the first support column 31 through the first fixing member 33. The second fixing member 35 is fixedly installed on the bearing rod 34. The drive component 5 is installed on the second fixing member 35. There are also two of each of the bearing rod 34 and the second fixing member 35, which ensures the stability of the drive component 5 installation.

[0075] Furthermore, the integrated bracket 3 also includes a third fixing member 36, a first fixing rod 37, a second fixing rod 38, a fourth fixing member 39, a connecting rod 310, and a guide rod 312. The third fixing member 36 is fixedly installed on the outside of the second support column 32. The end of the first fixing rod 37 is fixedly connected to the third fixing member 36. The end of the second fixing rod 38 is fixedly connected to both the third fixing member 36 and the first fixing member 33. The third fixing member 36, the first fixing rod 37, and the second fixing rod 38 can improve the stability of the assembly of the two first support columns 31 and the two second support columns 32. The fourth fixing member 39 is fixedly installed on the outside of the first support column 31 and the second support column 32 respectively. The connecting rod 310 is fixedly installed on the fourth fixing member 39. One end of the connecting rod 310 is fixedly installed with the fifth fixing member 311. The outer wall of the guide rod 312 is fixedly installed on the fifth fixing member 311. There are at least two guide rods 312, which can limit the two sides of the aluminum heat exchanger to ensure the stability of the aluminum heat exchanger on the conveyor belt 2. Loosening the fourth fixing member 39 and the fifth fixing member 311 can adjust the position of the guide rod 312.

[0076] Furthermore, the drive assembly 5 includes a drive cylinder 51, a mounting plate 52, a fixing frame 53, and a detection camera 54. The drive cylinder 51 is fixedly mounted on the top of the second fixing member 35, and the fixing frame 53 is fixedly connected to the top of the mounting plate 52. The output end of the drive cylinder 51 is connected to the fixing frame 53 via a transmission connection. The heating coil 4 is fixedly mounted on the bottom of the mounting plate 52. That is, the drive cylinder 51 can drive the heating coil 4 to move up and down through the fixing frame 53 and the mounting plate 52, so that the heating coil 4 can move to the processing area, the waiting area, or the storage area. The detection camera 54 is fixedly mounted on the top of the mounting plate 52. The bottom of the mounting plate 52 has a detection probe corresponding to the detection camera 54. The detection camera 54 can transmit the captured video images to the visual recognition system, which can identify the output. The conveyor belt 2 transports the position of the aluminum heat exchanger component, which, in conjunction with the positioning component 6, allows for dual identification of the aluminum heat exchanger component's position. This improves the accuracy of the high-frequency welding process of the aluminum heat exchanger component. Furthermore, the vision recognition system can identify the status of the high-frequency welding process of the aluminum heat exchanger component through photos taken by the detection camera 54. A protective cover 55 is fixedly connected to the bottom of the mounting plate 52 to protect the detection camera 54. The protective cover 55 is made of transparent material, so it will not affect the image captured by the detection camera 54. There is a certain gap between the heating coil 4 and the detection camera 54. Under the protection of the protective cover 55, the influence of the heating coil 4 on the detection camera 54 can be reduced. The protective cover 55 needs to be cleaned and maintained regularly to reduce its influence on the image captured by the detection camera 54.

[0077] Example 2: Based on Example 1, the positioning component 6 includes a positioning plate 61, a mounting component 62, a fixed housing 64, a sensing block 63, a connecting sleeve 66, a connector 67, and a rubber sleeve 68. The positioning plate 61 is rotatably mounted on one side of the first support column 31 via the mounting component 62. When the two positioning plates 61 are in a straight line, they can block and limit the aluminum heat exchanger component conveyed on the conveyor belt 2. The distance between the two positioning plates 61 is less than the width of the aluminum heat exchanger component, thereby preventing the aluminum heat exchanger component from passing through the gap between the two positioning plates 61. The fixed housing 64 is fixedly mounted on the front of the positioning plate 61. The back of the positioning plate 61 has an opening communicating with the inner cavity of the fixed housing 64. The sensing block 63 is slidably sleeved inside the opening. The sensing block 63 and the fixed housing 64... A first sensor 65 is installed in the middle. When the conveyor belt 2 conveys the aluminum heat exchanger component and makes pressure contact with the sensing block 63, the first sensor 65 can detect the pressure on the sensing block 63. Thus, the first sensor 65 feeds back a signal to the control terminal, that is, the aluminum heat exchanger component has been conveyed to the processing area, and the conveyor belt 2 can be stopped to convey it. The connecting sleeve 66 is fixedly connected to the inside of the fixed housing 64. The connecting piece 67 is fixedly connected to the front of the sensing block 63. The outer wall of the connecting piece 67 is slidably sleeved with the connecting sleeve 66. The rubber sleeve 68 is slidably sleeved with the outside of the connecting piece 67. The rubber sleeve 68 is located between the connecting sleeve 66 and the sensing block 63. The rubber sleeve 68 can buffer and protect the sensing block 63, reduce the impact force of the sensing block 63 on the first sensor 65, and thus improve the service life of the first sensor 65.

[0078] Furthermore, the mounting assembly 62 includes a mounting member 621, a fixing sleeve 622, a mounting sleeve 623, a connecting block 625, an arc rod 626, a first spring 627, and a second sensor 628. The mounting member 621 is fixedly mounted on the outside of the first support column 31. The end of the fixing sleeve 622 is fixedly connected to the mounting member 621. The mounting sleeve 623 is rotatably sleeved inside the fixing sleeve 622. One side of the fixing sleeve 622 has a slot 624 that matches the positioning plate 61. When the aluminum heat exchanger component needs to be discharged, the aluminum heat exchanger component can squeeze the two positioning plates 61 to rotate, thereby causing the positioning plates 61 to rotate relative to the fixing sleeve 622 through the mounting sleeve 623, thus allowing the aluminum heat exchanger component to be discharged between the two positioning plates 61. One side of the positioning plate 61 is fixedly connected to the mounting sleeve 623, and the connecting block 625 is fixedly connected to the mounting sleeve 626. Externally, the inner wall of the fixed sleeve 622 is provided with an arc groove. The connecting block 625 is slidably sleeved inside the arc groove. The arc rod 626 is fixedly installed inside the arc groove. The outer wall of the arc rod 626 is slidably inserted and sleeved with the connecting block 625. The first spring 627 is slidably sleeved outside the arc rod 626. The second sensor 628 is installed inside the arc groove. The end of the first spring 627 is pressed and attached to the second sensor 628 and the connecting block 625 respectively. The first spring 627 can exert an elastic force through the connecting block 625, so that after the aluminum heat exchanger component is discharged, the first spring 627 can give the positioning plate 61 a reset rotational elastic force, so that the positioning plate 61 rotates and resets. The second sensor 628 can detect the change of the elastic compression force of the first spring 627 and obtain the state of the positioning plate 61, so as to lock and limit the positioning plate 61 in the future.

[0079] Furthermore, the linkage component 7 includes a shaft 71, a locking block 72, a storage groove 73, and a drive sleeve 74. The bottom of the outer wall of the shaft 71 is movably sleeved with the mounting sleeve 623. The top of the mounting component 621 has a shaft hole that matches the shaft 71. The locking block 72 is fixedly connected to the outside of the shaft 71. The top of the inner wall of the mounting sleeve 623 has a locking groove. The bottom of the outer wall of the locking block 72 is slidably engaged with the inner cavity of the locking groove. When the locking block 72 is engaged between the mounting sleeve 623 and the mounting component 621, the mounting sleeve 62 can be... 3. Locking is performed to ensure the stability of the positioning plate 61 in limiting the aluminum heat exchanger components. The receiving groove 73 is opened at the bottom of the inner wall of the shaft hole. The top of the outer wall of the locking block 72 is slidably engaged with the inner cavity of the receiving groove 73. When the locking block 72 slides into the inside of the receiving groove 73, that is, when the bottom of the locking block 72 separates from the mounting sleeve 623, the locking of the positioning plate 61 can be released, and the aluminum heat exchanger components can push the positioning plate 61 to rotate. The driving sleeve 74 is sleeved on the top of the outer wall of the shaft 71, and the driving sleeve 74 and the mounting plate 52 are linked together.

[0080] Furthermore, the linkage assembly 7 also includes a connecting collar 75, a fixing block 76, a fixing plate 77, a fixing collar 78, a limiting block 79, and a second spring 710. The connecting collar 75 is slidably sleeved on the outside of the first support column 31. The fixing block 76 is fixedly connected between the connecting collar 75 and the drive sleeve 74. One end of the fixing plate 77 is fixedly connected to the mounting plate 52. The outer wall of the connecting collar 75 is fixedly connected to the fixing plate 77. Thus, when the drive cylinder 51 drives the mounting plate 52 to move up and down, the mounting plate 52 can drive the drive sleeve 74 to move up and down through the fixing plate 77, the connecting collar 75, and the fixing block 76. The fixing collar 78 is fixedly sleeved on the bottom of the inner cavity of the drive sleeve 74. The outer wall of the shaft 71 is slidably sleeved on the fixing collar 78. The limiting block 79 is fixedly connected to the top of the shaft 71. The second spring 710 is sleeved inside the drive sleeve 74. The bottom of the second spring 710 is pressed and fitted against the limiting block 79. Figure 8 As shown, when the drive assembly 5 moves the heating coil 4 down to the processing area, the bottom of the drive sleeve 74 is in contact with the mounting part 621, the second spring 710 is in a compressed state, and the locking block 72 on the outer wall of the shaft 71 is engaged with the mounting sleeve 623. At this time, the positioning plate 61 is in a locked state. When the drive assembly 5 moves the heating coil 4 to the processing area, the drive sleeve 74 rises, the second spring 710 is in an unfolded state, and the locking block 72 on the outer wall of the shaft 71 is still engaged with the mounting sleeve 623. At this time, the positioning plate 61 is in a locked state. When the drive assembly 5 moves the heating coil 4 to the storage area, the drive sleeve 74 rises, and the drive sleeve 74 can drive the shaft 71 to rise through the fixing collar 78 and the limiting block 79, thereby causing the locking block 72 on the outer wall of the shaft 71 to slide into the interior of the storage groove 73. The locking block 72 separates from the mounting sleeve 623, and the positioning plate 61 is locked.

[0081] Another objective of this invention is to provide a high-frequency welding method for aluminum heat exchanger components, comprising the following specific steps:

[0082] Step 1: When performing high-frequency welding on aluminum heat exchanger components, firstly, drive assembly 5 moves heating coil 4 to the processing area. At this time, drive assembly 5 drives drive sleeve 74 to descend. Drive sleeve 74 pushes shaft 71 to descend through second spring 710, so that shaft 71 drives the bottom of the outer wall of the locking block 72 to engage with the slot on the mounting sleeve 623, locking and limiting the positioning plate 61. When the conveyor belt 2 transports the aluminum heat exchanger component to the pressing induction block 63, the second sensor 628 feeds back the signal that the aluminum heat exchanger component has moved to the processing area, and at the same time stops the conveyor belt 2 from transporting the aluminum heat exchanger component.

[0083] Step 2: After the aluminum heat exchanger component moves to the processing area, the drive assembly 5 drives the heating coil 4 to move to the processing area. When the drive assembly 5 drives the heating coil 4 to be processed, there is a certain gap between the bottom of the drive sleeve 74 and the mounting part 621 at the top of the fixed sleeve 622. As a result, when the drive assembly 5 drives the heating coil 4 from the processing area to the processing area, the drive sleeve 74 continues to descend, and the drive sleeve 74 and the shaft 71 squeeze the second spring 710, so that the heating coil 4 is sleeved at the pipe opening of the aluminum heat exchanger component for high-frequency welding, so that the heating coil 4 performs high-frequency welding on the pipe opening of the aluminum heat exchanger component.

[0084] Step 3: After the high-frequency welding at the nozzle of the aluminum heat exchanger component is completed, the drive assembly 5 moves the heating coil 4 from the processing area to the storage area. The drive assembly 5 also moves the drive sleeve 74 upward. First, the second spring 710 extends and resets until the limiting block 79 at the top of the shaft 71 is in contact with the fixing collar 78. The drive sleeve 74 then moves the shaft 71 upward through the fixing collar 78 and the limiting block 79, causing the shaft 71 to move the locking block 72 into the storage groove 73. The locking block 72 no longer engages with the mounting sleeve 623. The conveyor belt 2 starts to transport the aluminum heat exchanger component. The aluminum heat exchanger component pushes the positioning plate 61 to rotate until the aluminum heat exchanger component is discharged. Under the action of the first spring 627... The positioning plate 61 rotates and resets, allowing for subsequent high-frequency welding of the aluminum heat exchanger components. After the positioning plate 61 resets, the change in the elastic coefficient of the first spring 627 can be detected by the second sensor 628 to indicate whether the positioning plate 61 has stabilized. Once the value detected by the second sensor 628 stabilizes, the drive assembly 5 can move the heating coil 4 to the processing area. At this time, the drive assembly 5 drives the drive sleeve 74 to descend. The drive sleeve 74 pushes the shaft 71 to descend via the second spring 710, causing the shaft 71 to engage with the bottom of the outer wall of the locking block 72 in the slot on the mounting sleeve 623, locking and limiting the positioning plate 61 so that the positioning plate 61 can block the aluminum heat exchanger components that are subsequently transported.
