Description

Technical Field

[0001] This invention relates to the field of cellular manufacturing technology, and more particularly to a cellular flat welding production line. Background Technology

[0002] Currently, aluminum honeycomb panels are widely used in civil construction, vehicle and ship decoration, and other fields. The finished product is generally a hexagonal honeycomb structure, with a single strip thickness of 0.04~0.06mm. They are processed into corrugated strips using roll forming technology. After forming, the corrugated strips need to be cut to a certain length, then transported by a handling device. After transport, the corrugated strips need to be positioned, and finally, two corrugated strips are stacked and welded together to form the final hexagonal honeycomb structure. However, current honeycomb welding production lines still have the following problems in their operation: (1) During roll forming, the material strip is very thin, and the processing accuracy is extremely high. The gap adjustment and stability of the pressure roller are also very important. The gap of the pressure roller needs to be precisely adjusted according to the material strip of different thicknesses. If there is a slight error, it will affect the forming accuracy. In severe cases, it will lead to roll forming failure and defective products, resulting in material waste. Ordinary roll forming devices are difficult to achieve this.

[0003] (2) During the cutting process, the formed waveband needs to be calibrated to ensure that each waveband segment has the same length. It also needs forward power transmission to continuously transport the waveband forward. Furthermore, it needs to apply a certain pressure to the waveband for clamping and positioning to prevent displacement during waveband cutting. In the past, multiple devices could only work together, which was complex to operate and costly.

[0004] (3) In the process of handling, ordinary gripper mechanisms are generally used to clamp the waveband for handling. However, after the waveband is handled, it needs to be positioned first, and then laser welding is performed. During welding, not only does the waveband need to be pressed in the longitudinal direction, but it also cannot affect the transmission of the laser light path. Ordinary handling devices cannot achieve the above functions themselves. They can only work by setting up multiple mechanisms, which is complicated to operate and costly.

[0005] (4) During positioning, in addition to pressing the waveband in the longitudinal direction, it is also necessary to realize the displacement of the waveband in the depth direction, and at the same time, it is also necessary to position it in the horizontal direction and limit it through the positioning pin. Finally, the multi-layer honeycomb structure is welded together, which is not easy to achieve with existing devices.

[0006] In summary, the aforementioned problems in the welding process of microporous honeycomb have become a technical challenge that urgently needs to be solved in the industry. Summary of the Invention

[0007] To overcome the shortcomings of existing technologies, this invention provides a honeycomb flat welding production line, which solves the problems of difficult and inaccurate adjustment of the gap between the pressure rollers and poor forming accuracy in previous roll forming devices, the complex and costly operation of honeycomb wavebands during the cutting process, the inability of previous waveband transport devices to press the wavebands tightly and to affect the transmission of laser light path, and the problem of positioning the wavebands in the horizontal direction and limiting them with positioning pins.

[0014] The glass is provided with rotating rods on both sides, and each rotating rod is equipped with several grippers. The two ends of the rotating rods are rotatably installed in the hanger seat. The ends of the rotating rods are fixedly connected to the rotating arm. The other end of the rotating arm is connected to the pull arm through the rotating shaft. The other end of the pull arm is connected to the sliding seat of the synchronous cylinder through the rotating shaft. The synchronous cylinder is fixed to the bottom of the substrate.

[0015] The waveband conveying device includes a conveyor frame mounted on a machine frame, a waveband conveying trough on the conveyor frame, an annular conveyor belt installed in the waveband conveying trough, and one end of the annular conveyor belt being driven by a conveyor motor.

[0016] The lifting mechanism includes a lifting frame located on the outside of the left upright plate. The lifting frame passes through an elongated hole on the left upright plate and is connected to the lifting plate. Guide rods for guiding the lifting frame are installed at both ends of the left upright plate. The middle of the lifting frame is fixedly connected to the lifting block. The lifting block is threadedly connected to the lead screw. The bottom of the lead screw is connected to the lifting motor.

[0017] The positioning pin mechanism includes a positioning rod located at the top of the right vertical plate. A positioning pin seat is located on the right side of the positioning rod, and several positioning pins are installed on the positioning pin seat. Several positioning pin holes that mate with the positioning pins are provided on the positioning rod. A front-to-back moving plate is located on the right side of the positioning pin seat, and a left-to-right moving plate is located below the front-to-back moving plate. The bottom sides of the left-to-right moving plate are mounted on the frame via left-to-right slide rails. The bottom center of the left-to-right moving plate is driven by a left-to-right moving motor that drives a lead screw.

The front and rear guide rods are fixed by a guide rod seat, and the guide rod seat is mounted on the left-to-right moving plate via a second front-to-back slide rail.

[0018] The present invention adopts the above-described solution and has the following advantages: (1) By installing a lever-type adjustment mechanism connected to the lifting seat on the top plate, the height of the lifting seat and the lifting pressure roller can be precisely adjusted by the lever-type adjustment mechanism. The lifting seat drives the lifting pressure roller to move up and down along the four guide columns. The operation is stable and reliable. After the distance between the lifting pressure roller and the fixed pressure roller is adjusted, the drive motor is started. The drive wheel drives the lifting pressure roller and the fixed pressure roller to rotate synchronously in opposite directions through the synchronous belt. This is used to roll the material strip. The material strip can be conveyed backward while it is being rolled. The defect rate is low and the forming accuracy is greatly improved.

[0019] (2) By installing a vertical roller above a plate with a waveband conveyor groove, the outer circumferential surface of the vertical roller is provided with a spiral groove that matches the waveband. The vertical roller is driven to rotate by a roller motor and its up-down and left-right positions are adjusted by a cross adjustment mechanism. When the vertical roller rotates, its spiral groove matches the groove on the waveband, which can provide power for the forward conveying of the waveband. The length of the waveband can be set by the number of rotations of the vertical roller. When the set number of rotations is reached, the vertical roller stops rotating. At this time, the length of the waveband is exactly the required length. The vertical roller can also press the waveband, which can prevent the waveband from shifting when the cutting tool cuts the waveband. This invention realizes multiple functions such as length setting, conveying and pressing through the vertical roller. It is easy to operate and reduces equipment costs.

[0020] (3) The transport mechanism is moved by the X-axis kinematic pair and the Y-axis kinematic pair. First, the transport mechanism is moved to the water tank to make the glass wet. Then, the transport mechanism is moved to the waveband conveyor. The wet glass is used to adsorb and transport the waveband, realizing the transport function of the waveband. During subsequent welding, the waveband can be pressed and fixed directly by the glass. The laser can directly pass through the glass to weld the waveband without affecting the light path transmission of the laser. The glass realizes multiple functions such as transporting, welding and fixing the waveband, and not affecting the light path transmission of the laser. It is a multi-purpose device, which simplifies the structure and reduces the equipment cost.

[0021] (4) By providing a cavity between the left and right vertical plates, and a lifting plate is provided in the cavity, the waveband can be displaced in the longitudinal direction. By setting a positioning pin mechanism to position the waveband in the horizontal direction, the horizontal positioning of the waveband is realized and the positioning pin is used to limit it. Finally, a multi-layer honeycomb structure is formed by welding. Attached Figure Description

Detailed Implementation

[0033] To clearly illustrate the technical features of this solution, the invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0034] like Figure 1 As shown, a honeycomb flat welding production line includes a frame 101. A roll forming device 102, a fixed length cutting device 103, a conveying device 104 and a positioning device 105 are installed on the frame 101 from front to back. A welding device 106 is provided on one side of the positioning device 105. like Figure 2-3 As shown, the roll forming device 102 includes a base plate 1, on which a U-shaped fixed seat 2 is provided. A fixed pressure roller 4 is installed in the fixed seat 2 through a fixed shaft 3. One end of the fixed shaft 3 extends out of the fixed seat 2 and is connected to a fixed rotating wheel 5. Guide posts 6 are vertically installed at the four corners of the fixed seat 2. An inverted U-shaped lifting seat 7 is slidably installed on the guide posts 6. A lifting pressure roller 9 is installed in the lifting seat 7 through a lifting shaft 8. One end of the lifting shaft 8 extends out of the lifting seat 7 and is connected to a lifting rotating wheel 10. The fixed rotating wheel 5 and the lifting rotating wheel are also connected to the fixed rotating wheel 10. 10 is connected to the drive wheel 13 of the drive motor 12 mounted on the base plate 1 via the synchronous belt 11. The drive wheel 13 drives the lifting pressure roller 9 to rotate synchronously in opposite directions with the fixed pressure roller 4 via the synchronous belt 11 for roll forming of the material strip. The material strip can be stainless steel, high temperature alloy, aluminum alloy, copper, etc. A top plate 14 is fixedly installed on the top of the guide column 6. A lever-type adjustment mechanism connected to the lifting seat 7 is installed on the top plate 14. The lever-type adjustment mechanism is used to adjust the height of the lifting seat 7 and the lifting pressure roller 9.

[0035] The lever-type adjustment mechanism includes a vertical plate 15 fixed on the top plate 14, a vertically arranged slide block 16 fixed on the vertical plate 15, a slide rail 17 slidably installed inside the slide block 16, a bent seat 18 installed on the top of the slide block 16, and a micrometer screw 19 installed on the bent seat 18. The micrometer screw 19 can be accurate to 0.01mm and has extremely high adjustment precision. The bottom of the micrometer screw 19 is fixedly connected to the slide rail 17. The slide rail 17 is bolted to the side of the slide rail 20. The bottom of the slide rail 20 is rotatably connected to one end of the lever 22 through a first rotating shaft 21. The lever 22 is rotatably connected to the support rod 24 fixed on the top plate 14 through a second rotating shaft 23. The other end of the lever 22 is rotatably connected to the top of the pull rod 26 through a third rotating shaft 25. The bottom end of the pull rod 26 passes through a through hole on the top plate 14 and is rotatably connected to the top of the lifting seat 7 through a fourth rotating shaft 27. During adjustment, rotating the micrometer screw 19 causes the slide rail 17 to move up and down along the slide seat 18. The slide rail 17 and the slide rail seat 20 move synchronously. When the slide rail seat 20 moves downward, it causes the first rotating shaft 21 to descend. With the support of the second rotating shaft 23, the lever 22 causes the third rotating shaft 25 to rise, which in turn causes the lifting seat 7 to rise via the pull rod 26 and the fourth rotating shaft 27. Conversely, when the slide rail seat 20 moves upward, it causes the first rotating shaft 21 to rise. With the support of the second rotating shaft 23, the lever 22 causes the third rotating shaft 25 to descend, which in turn causes the lifting seat 7 to descend via the pull rod 26 and the fourth rotating shaft 27. Ultimately, this makes the distance between the lifting pressure roller 9 and the fixed pressure roller 4 match the material strip of different thicknesses, improving the rolling accuracy.

[0036] The distance between the second rotating shaft 23 and the first rotating shaft 21 is greater than the distance between the second rotating shaft 23 and the third rotating shaft 25, which can save effort.

[0037] The slide block 16 and the slide rail 17 are slidably connected by a dovetail groove structure.

[0038] The fixed pressure roller 4 and the lifting pressure roller 9 are respectively equipped with flanges 28 by several bolts on both sides, which can make the fixed pressure roller 4 and the lifting pressure roller 9 more secure and improve the stability during rolling.

[0039] A tensioning wheel 30 for tensioning the synchronous belt 11 is mounted on the base plate 1 via a tensioning wheel frame 29.

[0040] The synchronous belt 11 is an annular toothed synchronous belt. The lifting wheel 10 and the fixed wheel 5 are respectively provided with teeth that mesh with the synchronous belt 11. The lifting wheel 10 is located inside the synchronous belt 11, and the fixed wheel 5 is located outside the synchronous belt 11, so as to realize the synchronous opposite rotation of the lifting wheel 10 and the fixed wheel 5.

[0041] Working principle of roll forming device: Before operation, the height of the lifting roller 9 needs to be precisely adjusted. During adjustment, the micrometer screw 19 is rotated, causing the slide rail 17 to move up and down along the slide block 16. The slide rail 17, along with the slide rail seat 20, moves synchronously. The slide rail seat 20 then drives the pull rod 26 via the lever 22, causing the lifting seat 7 to move up and down. This ultimately achieves the height adjustment of the lifting roller 9, matching the distance between the lifting roller 9 and the fixed roller 4 to the thickness of the strip. After adjustment, the roll forming process can begin. The strip is placed between the lifting roller 9 and the fixed roller 4. Then, the drive motor 12 is started. The drive wheel 13 of the drive motor 12 drives the fixed rotating wheel 10 and the lifting rotating wheel 5 to rotate via the synchronous belt 11, causing the lifting roller 9 and the fixed roller 4 to rotate synchronously in opposite directions. The strip is then roll-formed between the lifting roller 9 and the fixed roller 4, and can be conveyed backwards during the roll forming process.

[0042] like Figure 4-5 As shown, the fixed-length cutting device includes a frame 31, on which a flat plate 32 is provided. The upper surface of the flat plate 32 is provided with a waveband conveying groove 33. A cutting blade is provided on the rear side of the flat plate 32. A vertical rotating wheel 34 is provided above the flat plate 32. The outer circumferential surface of the vertical rotating wheel 34 is provided with a spiral groove 35 that cooperates with the waveband. The lead of the spiral groove 35 is the same as the step distance of the waveband. The vertical rotating wheel 34 is used to perform fixed-length conveying and pressing of the waveband. The vertical rotating wheel 34 is connected to the output shaft of the rotating wheel motor 37 mounted on the adjusting plate 36. The adjusting plate 36 is connected to the frame 31 through a cross adjusting mechanism.

[0043] The cross adjustment mechanism includes a longitudinal adjustment mechanism mounted on the frame 31. The longitudinal adjustment mechanism includes a longitudinal slide 38, a longitudinal slide rail 39 slidably mounted inside the longitudinal slide 38, a longitudinal bent seat 40 mounted on the top of the longitudinal slide 38, a longitudinal micrometer screw 41 mounted on the longitudinal bent seat 40, and the bottom of the longitudinal micrometer screw 41 fixedly connected to the longitudinal slide rail 39. A transverse adjustment mechanism is mounted on the side of the longitudinal slide rail 39. The transverse adjustment mechanism includes a transverse slide 42, a transverse slide rail 43 slidably mounted inside the transverse slide 42, a transverse bent seat 44 mounted at the end of the transverse slide 42, a transverse micrometer screw 45 mounted on the transverse bent seat 44, the transverse micrometer screw 45 fixedly connected to the transverse slide rail 43, and the transverse slide rail 43 fixedly connected to the adjustment plate 36. The longitudinal micrometer screw 41 and the transverse micrometer screw 45 are accurate to 0.01mm, providing extremely high adjustment precision. During adjustment, rotating the longitudinal micrometer screw 41 causes the longitudinal slide rail 39 to move up and down along the longitudinal slide block 38. Rotating the transverse micrometer screw 45 causes the transverse slide rail 43 to move left and right along the transverse slide block 42, thereby causing the adjusting plate 36 to move up and down and left and right. Ultimately, this allows for adjustment of the vertical rotating wheel 34's position, matching it with wavebands of different thicknesses and ensuring that the spiral groove 35 on its outer circumferential surface precisely matches the groove of the waveband.

[0044] The cutting tool is mounted on the frame via a Y-axis motion pair 46, which can be a motor lead screw transmission structure to adjust the vertical position of the cutting tool.

[0045] The cutting tool includes two gripper cylinders 47, which are connected to an upper blade holder 48 and a lower blade holder 49 respectively. An upper blade 50 is installed on the upper blade holder 48, and a lower blade 51 is installed on the lower blade holder 49. When the gripper cylinders 47 are working, they drive the upper blade 50 and the lower blade 51 to move in opposite directions synchronously, thereby cutting the waveband.

[0046] Working principle of fixed-length cutting device: Before operation, the vertical and horizontal positions of the vertical roller 34 need to be precisely adjusted. During adjustment, rotate the longitudinal micrometer screw 41, which will drive the longitudinal slide rail 39 to move up and down along the longitudinal slide block 38. Rotate the transverse micrometer screw 45, which will drive the transverse slide rail 43 to move left and right along the transverse slide block 42, thereby driving the adjustment plate 36 to move up and down and left and right. Finally, the vertical and horizontal positions of the vertical roller 34 can be adjusted so that the vertical roller 34 can match the wavebands of different thicknesses and make the spiral groove 35 on its outer circumferential surface precisely match the groove of the waveband. Then, the rotary motor 37 is started, driving the vertical rotary wheel 34 to rotate. Under the action of the spiral groove 35, it not only drives the belt forward, providing power for the forward transport of the belt, but also uses the rotation number of the vertical rotary wheel 34 to set the length of the belt. When the set number of rotations is reached, the rotary motor 7 stops working, and the vertical rotary wheel 4 stops rotating. At this time, the length of the belt is exactly the required length. Then, the cutting work is performed. The gripper cylinder 47 is started, driving the upper blade 50 and the lower blade 51 to move synchronously in opposite directions to cut the belt. Repeating the above actions, the entire belt can be cut into several segments of the same length for use in the next process.

[0047] like Figure 6-8 As shown, the conveying device includes a waveband conveyor. A water tank 52 is provided on the frame 101 directly behind the waveband conveyor. An X-axis motion pair 53 is installed on the frame 101 directly above the waveband conveyor. A Y-axis motion pair 54 is installed at the bottom of the X-axis motion pair 53. A conveying mechanism 55 is installed at the bottom of the Y-axis motion pair 54. The conveying mechanism 55 includes a base plate 56. A perforation 57 is provided in the middle of the base plate 56. A hanging rod 58 is installed at the bottom of each end of the base plate 56. A glass seat 59 is installed at the bottom of the hanging rod 58. A glass 60 is installed between the two glass seats 59. The waveband is adsorbed and conveyed by the glass 60 after it is dipped in water in the water tank 52.

[0048] The outer side of the suspension rod 58 is provided with a suspension rod seat 61 fixed to the bottom of the base plate 56. The suspension rod 58 is movably inserted into the suspension rod seat 61, and there is a space for the suspension rod 58 to move between the suspension rod seat 61 and the base plate 56. The top of the suspension rod 58 is provided with a limiting step, and a compression spring 62 is sleeved on the outer side of the suspension rod 58 between the suspension rod seat 61 and the glass seat 59. This design allows the suspension rod 58 to have a certain elastic buffering capacity. When the glass 60 is pressed down, the glass seat 59 can push the suspension rod 58 to move upward, and the compression spring 62 is compressed, thereby achieving a buffering effect.

[0049] The glass 60 has rotating rods 63 on both sides, each rod 63 having several grippers 64. Both ends of the rotating rods 63 are rotatably mounted in the lifting rod seats 61. The ends of the rotating rods 63 are fixedly connected to rotating arms 65, and the other end of the rotating arms 65 is connected to a pull arm 66 via a rotating shaft. The other end of the pull arm 66 is connected to a sliding seat 67 of a synchronous cylinder 68 via a rotating shaft. The synchronous cylinder 68 is fixed to the bottom of the substrate 56. The grippers 64 on both sides of the glass 60 can straighten and assist in clamping the waveband. When the waveband is attracted to the bottom of the glass 60, the synchronous cylinder 68 is activated, causing the two sliding seats 67 to move in opposite directions. The sliding seats 67 then cause the pull arm 66 to move in opposite directions. The pull arm 66, through the rotating arms 65, drives the two rotating rods 63 to rotate synchronously, bringing the grippers 64 on the two rotating rods 63 closer together. This straightens the waveband at the bottom of the glass 60 and assists in clamping the waveband during transport. Conversely, when it is necessary to release, the synchronizing cylinder 68 is activated, which drives the two sliding seats 67 to move in the same direction. The sliding seats 67 drive the pull arm 66 to move in the same direction. The pull arm 66 drives the two rotating rods 63 to rotate synchronously through the rotating arm 65, so that the grippers 64 on the two rotating rods 63 move away from each other and release the waveband.

[0050] The waveband conveying device includes a conveyor frame 69 mounted on a frame 101. The conveyor frame 69 is provided with a waveband conveying trough. An annular conveyor belt 70 is installed in the waveband conveying trough. One end of the annular conveyor belt 70 is driven by a conveyor motor 71. The conveyor motor 71 can drive the annular conveyor belt 70 to rotate. The annular conveyor belt 70 can convey the waveband in the waveband conveying trough forward.

[0051] Working principle of the conveying device: During operation, the conveyor motor 71 starts, driving the annular conveyor belt 70 to rotate. The annular conveyor belt 70 transports the waveband in the waveband conveying trough forward. When transporting the waveband, the X-axis kinematic pair 53 drives the Y-axis kinematic pair 54 to move horizontally, and the Y-axis kinematic pair 54 drives the transport mechanism 55 to move vertically. First, the transport mechanism 55 is moved to the water tank 52 to wet the glass 60. Then, the transport mechanism 55 is moved to the waveband conveying device, where the wet glass 60 adheres to the waveband on the conveyor frame 69. The Y-axis kinematic pair 54 then drives the glass... During the downward pressing process, the glass seat 59 can push the lifting rod 58 upward, compressing the compression spring 62, thus providing a buffering effect. After the glass 60 adheres to the bottom of the waveband, the synchronous cylinder 68 is activated, driving the two sliding seats 67 to move in opposite directions. The sliding seats 67 drive the pull arm 66 to move in opposite directions, and the pull arm 66 drives the two rotating rods 63 to rotate synchronously through the rotating arm 65, causing the grippers 64 on the two rotating rods 63 to move closer to each other. On the one hand, this can straighten the waveband at the bottom of the glass 60, and on the other hand, it can play an auxiliary clamping role during transportation, thus realizing the function of transporting the waveband. During subsequent welding, the glass 60 can be directly used to press and fix the waveband. The laser can directly pass through the perforation 57 on the substrate 56 and the glass 60 to weld the waveband without affecting the transmission of the laser beam.

[0052] like Figure 9-10 As shown, the positioning device includes a left vertical plate 73 and a right vertical plate 74. A cavity 75 is provided between the left vertical plate 73 and the right vertical plate 74. A lifting plate 76 is movably provided in the cavity 75. A lifting mechanism connected to the lifting plate 76 is provided on the outside of the left vertical plate 73. A positioning pin mechanism for positioning the waveband in the horizontal direction is provided on the outside of the right vertical plate 74.

[0053] The lifting mechanism includes a lifting frame 77 located outside the left upright plate 73. The lifting frame 77 passes through an elongated hole 78 on the left upright plate 73 and connects to the lifting plate 76. Guide rods 79 are installed at both ends of the left upright plate 73 to guide the lifting frame 77. The middle part of the lifting frame 77 is fixedly connected to a lifting block 80, which is threadedly connected to a lead screw 81. The bottom of the lead screw 81 is connected to a lifting motor 82. When the lifting motor 82 is working, it can drive the lead screw 81 to rotate, which in turn drives the lifting block 80 to move up and down. The lifting block 80 then drives the lifting frame 77 to move up and down. The lifting frame 77 passes through the elongated hole 78 on the left upright plate 73 and drives the lifting plate 76 to move up and down, thus realizing the lifting of the lifting plate 76. The waveband to be welded is placed on the lifting plate 76. After each layer is welded, the lifting plate 76 lowers by one layer, which can realize the displacement of the waveband in the depth direction and has a storage space that can accommodate multiple layers of honeycomb.

[0054] The positioning pin mechanism includes a positioning rod 83 located at the top of the right vertical plate 74. A positioning pin seat 84 is located on the right side of the positioning rod 83, and several positioning pins 85 are mounted on the positioning pin seat 84. The positioning rod 83 has several positioning pin holes that mate with the positioning pins 85. A front-to-back moving plate 86 is located on the right side of the positioning pin seat 84. A left-to-right moving plate 87 is located below the front-to-back moving plate 86. The bottom sides of the left-to-right moving plate 87 are mounted on the frame via left-to-right slide rails 88. The bottom center of the left-to-right moving plate 87 is driven by a left-to-right moving motor 89 that drives a lead screw, allowing adjustment of its left and right positions. The bottom sides of the front-to-back moving plate 86 are connected via a first... The front and rear slide rails 90 are mounted on the left and right moving plates 87. The bottom center of the front and rear moving plates 86 is driven by the lead screw driven by the front and rear moving motor 91. The top of the front and rear moving plates 86 is provided with a fixed frame 92. The fixed shaft 93 is installed in the fixed frame 92. The fixed shaft 93 moves through the positioning pin seat 94 and is fixedly connected to the middle of the positioning rod 83. The two ends of the positioning rod 83 and the positioning pin seat 84 are respectively provided with front and rear guide rods 94. The front and rear guide rods 94 are fixedly inserted through the positioning pin seat 84 and are movably connected to the positioning rod 83. The front and rear guide rods 94 are fixed by the guide rod seat 95. The guide rod seat 95 is mounted on the left and right moving plates 87 through the second front and rear slide rails 96.

[0055] Working principle of the positioning pin mechanism: During positioning, the forward and backward moving motor 91 drives the forward and backward moving plate 86 to move forward along the first forward and backward slide rail 90 via the lead screw. The forward and backward moving plate 86 drives the fixed frame 92 and fixed shaft 93 on it to move forward. The fixed shaft 93 first drives the positioning rod 83 to move forward along the forward and backward guide rods 94 to initially clamp the waveband placed on the lifting plate 76. At this time, the positioning pin seat 84 does not move. When the fixed frame 82 contacts the positioning pin seat 84, the fixed frame 92 then moves the positioning pin seat 84, the forward and backward guide rods 94, and the guide rod seat 95 forward along the second forward and backward slide rail 96. The positioning pin 85 on the positioning pin seat 84 passes through the positioning pin hole on the positioning rod 83 and inserts forward into the honeycomb holes of the two layers of waveband for limiting. At the same time, the fixed frame 92 pushes the positioning pin seat 84, and the positioning pin seat 84 pushes the positioning rod 83 to clamp and position the waveband in the horizontal direction. When positioning is not required, the forward and backward moving motor 91 drives the forward and backward moving plate 86 to move backward along the first forward and backward slide rail 90 via the lead screw. The fixed shaft 93 on the forward and backward moving plate 86 drives the positioning rod 83, and the positioning rod 83 drives the positioning pin seat 84 to move backward away from the waveband, thereby releasing the waveband.

[0056] The entire production line works as follows: First, the strip is roll-formed by the roll forming device 102, and the strip can be conveyed backward to the fixed-length cutting device 103 at the same time. The fixed-length cutting device 103 cuts the entire strip into several segments of the same length and conveys them backward to the transport device 104. The transport device 104 can transport the strip to the positioning device 105. The positioning device 105 positions the strip in the horizontal direction. When two layers of strip are stacked, the glass 60 of the transport device 104 presses and positions the strip in the vertical direction. Then, the welding device 106 is started to perform welding. The laser of the welding device 106 can directly pass through the perforation 57 and the glass 60 to weld the two layers of strip. After welding, the lifting mechanism can drive the strip to descend step by step. Each time a layer is welded, the lifting plate 76 descends by one layer, which can realize the displacement of the strip in the depth direction and form a storage space that can accommodate multiple layers of strip. Repeating the above actions can produce the required multi-layer honeycomb structure.
