Description

Technical Field

[0001] This invention relates to an automatic tube bundle assembly machine, belonging to the field of tube bundle assembly technology. Background Technology

[0002] The pneumatic body panel assembly features four nylon tube bundles, each connected to one of four bamboo-joint reverse-tooth connectors on the panel. These four nylon tube bundles have a unique structure, with each tube having a different shape and multiple bends. Precise alignment and positioning of the nylon tube bundles are crucial during assembly. The pneumatic body panel assembly is typically assembled manually using a press-fit method, which is difficult and cannot guarantee the correct alignment and positioning of the nylon tube bundles. This can even lead to misalignment or breakage of the tube bundles. Furthermore, manual assembly is inefficient and cannot meet production demands. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing an automated tube bundle assembly machine that improves assembly efficiency.

[0004] To achieve the objective, the technical solution adopted by this invention is: An automatic tube bundle assembly machine includes a frame and a through-plate fixture, a fixture driving mechanism, a tube clamping mechanism, a tube clamping driving mechanism, and a controller located on the frame. The through-plate fixture holds a through-plate with multiple hollow tube connectors. The fixture driving mechanism includes a lifting cylinder, a rotating cylinder, and a first moving cylinder, which respectively drive the through-plate fixture to move up and down, rotate, and move back and forth. The tube clamping mechanism is used to clamp tube bundles. The number of tube clamping mechanisms and the number of tube bundles are the same as the number of tube connectors. Each tube bundle has a different mark. Multiple sets of tube clamping mechanisms are arranged side-by-side, and each set of tube clamping mechanisms has the same mark as the corresponding clamped tube bundle. The tube clamping driving mechanism and the tube clamping mechanism are both located above the through-plate fixture. The tube clamping driving mechanism drives the tube clamping mechanism and the clamped tube bundle to move left and right. The fixture driving mechanism drives the through-plate fixture and the through-plate to move, so that each tube connector is sequentially assembled with its corresponding tube bundle.

[0005] As a further optimization of the above technical solution: the through plate is provided with four pipe joints, the four pipe joints are arranged in two rows and two columns, the tube bundle is provided with a total of four, and the pipe clamp mechanism is provided with four sets and arranged alternately from left to right.

[0006] As a further optimization of the above technical solution: the fixture driving mechanism further includes a first moving plate and a second moving plate. Two first slide rails are fixed on the first platform of the frame, and each of the two first slide rails is equipped with a first slider. Both ends of the first moving plate are fixed to the first slider. A first moving cylinder is fixed to the bottom of the first platform, and the piston rod of the first moving cylinder is connected to the first moving plate. The first moving cylinder drives the first moving plate and the first slider to move on the first slide rails. A mounting plate is fixed to the bottom of the first moving plate, and the lifting cylinder is fixed to the mounting plate. Two guide sleeves are embedded in the first moving plate, and a guide post is inserted in each of the two guide sleeves. The second moving plate is fixed to the top of the two guide posts, and a connecting plate is fixed to the bottom of the two guide posts. The piston rod of the lifting cylinder is fixed to the connecting plate. The lifting cylinder drives the connecting plate, the guide posts, and the second moving plate to move up and down relative to the first moving plate. The rotary cylinder is fixed to the bottom of the second moving plate. The plate-passing fixture is located above the second moving plate. The output shaft of the rotary cylinder passes through the second moving plate and is fixed to the plate-passing fixture. The rotary cylinder drives the plate-passing fixture to rotate.

[0007] As a further optimization of the above technical solution: a second plate is fixed on the frame, the second plate being located above the first plate. The pipe clamp drive mechanism and the pipe clamp mechanism are both located on the second plate, so that the pipe clamp drive mechanism and the pipe clamp mechanism are both located above the through-plate fixture. The pipe clamp drive mechanism includes a drive motor, a lead screw, a transmission seat, a fixed seat, and a third moving plate. The drive motor and the fixed seat are both fixed on the second plate. One end of the lead screw is connected to the drive motor, and the other end of the lead screw is fixed to the fixed seat. The transmission seat is threaded onto the lead screw and fixed to the bottom surface of the third moving plate. Two second slide rails are fixed on the second plate, and each of the two second slide rails is provided with a second slider. The third moving plate is fixed on the two second sliders. The pipe clamp mechanism is mounted on the third moving plate. The drive motor drives the lead screw to rotate, thereby driving the transmission seat to move laterally relative to the lead screw, so that the third moving plate and the pipe clamp mechanism move laterally.

[0008] As a further optimization of the above technical solution: each set of pipe clamping mechanisms includes a clamping cylinder, a push plate, and two clamping jaws. The clamping cylinder is fixed to the third moving plate, and the piston rod of the clamping cylinder is connected to the push plate. The tails of the two clamping jaws are integrally formed with connecting rods, and the two connecting rods are provided with inclined moving grooves. The ends of the two moving grooves near the push plate are closed ends, and the ends of the two moving grooves away from the push plate are open ends. Two bolts are provided on the push plate, and the ends of the two bolts pass through the two moving grooves respectively and are fitted with nuts. The end of the push plate is slidably installed in the moving groove through the bolts. The push plate drives the bolts to move in the moving groove. The two clamping jaws are hinged to the third moving plate through hinge shafts, and clamping grooves are provided on the opposite sides of the two clamping jaws.

[0009] As a further optimization of the above technical solution: a third slide rail and a limiting block are also fixed on the third moving plate. A third slider is slidably provided on the third slide rail. The bottom of the push plate is fixed on the third slider. Limiting grooves are provided on the opposite sides of the two gripping claws. When the two gripping claws are brought together, the limiting block is located in the limiting groove of the two gripping claws.

[0010] As a further optimization of the above technical solution: the frame is also provided with four clamping buttons connected to the controller. The four clamping buttons respectively control the clamping cylinders in the four sets of pipe clamping mechanisms to drive the push plate forward, so that the two clamping jaws close together to clamp the tube bundle. At the same time, the four clamping buttons are respectively provided with the same markings corresponding to the four sets of pipe clamping mechanisms.

[0011] As a further optimization of the above technical solution, it also includes a tube bundle positioning mechanism, which includes a first positioning plate, a second positioning plate, a third positioning plate, and a fourth positioning plate located on the top of the frame. The first positioning plate, the second positioning plate, the third positioning plate, and the fourth positioning plate are all located above the tube clamping mechanism. The tube bundle positioning mechanism also includes a support plate and four protrusions located on the support plate. The support plate is located below the tube clamping mechanism. The four protrusions are spaced apart and located directly below the midpoint of two of the clamping claws in the four sets of tube clamping mechanisms. One end of the tube bundle is fitted onto the protrusion, and the other end of the tube bundle contacts the corresponding first positioning plate / second positioning plate / third positioning plate / fourth positioning plate, so that the tube bundle is positioned.

[0012] As a further optimization of the above technical solution: the tube bundle positioning mechanism further includes a first moving mechanism and a second moving mechanism fixed on the frame. The first moving mechanism includes a fifth moving cylinder and a second moving cylinder. Both the fifth moving cylinder and the second moving cylinder are connected to the top of the frame through a mounting connecting plate. The piston rod of the fifth moving cylinder is connected to the first positioning plate and the second positioning plate and drives the first positioning plate and the second positioning plate to move back and forth. The piston rod of the second moving cylinder is connected to the third positioning plate and the fourth positioning plate and drives the third positioning plate and the fourth positioning plate to move up and down. The second moving mechanism includes a third moving cylinder and a fourth moving cylinder. The third moving cylinder is fixed to the frame. The piston rod of the third moving cylinder is connected to the fourth moving cylinder. The piston rod of the fourth moving cylinder is connected to the bottom of the pallet. The third moving cylinder drives the fourth moving cylinder and the pallet to move up and down. The fourth moving cylinder drives the pallet to move laterally.

[0013] As a further optimization of the above technical solution: when all four tube bundles are positioned and clamped by the corresponding tube clamping mechanism, the third moving cylinder drives the support plate and the protrusion to move downward, so that the bottom of the tube bundle is disengaged from the protrusion; the fourth moving cylinder drives the support plate and the protrusion to move to the left; the fifth moving cylinder drives the first positioning plate and the second positioning plate to move backward and disengage from the tube bundle; the second moving cylinder drives the third positioning plate and the fourth positioning plate to move upward and disengage from the tube bundle, so that the tube bundle positioning mechanism is separated from all the tube bundles.

[0014] As a further optimization of the above technical solution: the through plate fixture has a relief groove, the relief groove is provided with four positioning posts, the four pipe joints on the through plate are respectively sleeved on the four positioning posts, and the nut seat at the bottom of the through plate is located in the relief groove.

[0015] As a further optimization of the above technical solution: the frame is also equipped with an air source processing unit, which is used to provide compressed air to the cylinder, and the frame is also equipped with several cooling fans.

[0016] As a further optimization of the above technical solution: the frame is also equipped with a start button and a reset button connected to the controller. Pressing the start button starts the assembly operation, and pressing the reset button resets each component to the initial state of waiting for loading.

[0017] Compared with existing technologies, this invention achieves automatic assembly between four nylon tube bundles and four pipe joints on the guide plate, overcoming the instability of manual assembly operations and ensuring that the tube bundles and pipe joints can be assembled in place. Furthermore, the force of the lifting cylinder driving the guide plate upward is uniform and vertical, which can prevent tube bundle breakage during assembly. At the same time, automatic assembly not only greatly improves tube bundle assembly efficiency and meets production needs, but also significantly reduces assembly costs. The tube bundles are positioned by the protruding post on the tube bundle positioning mechanism and the first positioning plate, second positioning plate, third positioning plate and fourth positioning plate, ensuring that the four tube bundles are correctly oriented and have high positional accuracy during assembly. The rotary cylinder of the fixture driving mechanism drives the guide plate fixture and the guide plate to rotate, realizing the assembly of the opposite side pipe joints on the guide plate. The assembly process is reasonable and smooth. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. For example... Figure 1-5 As shown, the automatic tube bundle assembly machine includes a frame 8 and a through-plate fixture 3, a fixture drive mechanism 4, a tube clamping mechanism 5, a tube clamping drive mechanism 7, and a controller 9 located on the frame 8. A through-plate 1 is placed on the through-plate fixture 3, and multiple hollow tube connectors 11 are provided on the through-plate 1. The fixture drive mechanism 4 includes a lifting cylinder 41, a rotating cylinder 42, and a first moving cylinder, which respectively drive the through-plate fixture 3 to move up and down, rotate, and move back and forth. The tube clamping mechanism 5 is used to clamp the tube bundles 2. The number of tube clamping mechanisms 5 and the number of tube bundles 2 are the same as the number of tube connectors 11. Each tube bundle 2 has a different mark. Multiple sets of tube clamping mechanisms 5 are arranged side by side, and each set of tube clamping mechanisms 5 has the same mark as the corresponding clamped tube bundle 2. Both the pipe clamp drive mechanism 7 and the pipe clamp mechanism 5 are located above the through plate fixture 3. The pipe clamp drive mechanism 7 drives the pipe clamp mechanism 5 and the clamped pipe bundle 2 to move left and right. The fixture drive mechanism 4 drives the through plate fixture 3 and the through plate 1 to move, so that each pipe joint 11 is assembled with each corresponding pipe bundle 2 in sequence.

[0025] In the above technical solution: the through plate 1 is provided with four pipe joints 11, which are arranged in two rows and two columns. There are four tube bundles 2, which are different in shape and have multiple bends. The four tube bundles 2 are marked with different marks, such as serial numbers ①, ②, ③, ④, or colors red, yellow, orange, and green. The marks can be affixed to the corresponding positions of the tube bundles 2 with stickers. Correspondingly, there are four sets of pipe clamping mechanisms 5, which are arranged alternately from left to right. The four sets of pipe clamping mechanisms 5 are marked with the same marks as the four tube bundles 2.

[0026] In the above technical solution: the through plate fixture 3 has a relief groove 31, and four positioning posts 32 are provided in the relief groove 31. The four pipe joints 11 on the through plate 1 are respectively sleeved on the four positioning posts 32, and the nut seat at the bottom of the through plate 1 is located in the relief groove 31.

[0027] In the above technical solutions: such as Figure 2 As shown, the fixture driving mechanism 4 also includes a first moving plate 43 and a second moving plate 44. Two first slide rails 45 are fixed on the first plate 81 of the frame 8, and each of the two first slide rails 45 is equipped with a first slider. Both ends of the first moving plate 43 are fixed to the first sliders. A first moving cylinder is fixed to the bottom of the first plate 81, and the piston rod of the first moving cylinder is connected to the first moving plate 43. The first moving cylinder drives the first moving plate 43 and the first slider to move on the first slide rails 45. A mounting plate 49 is fixed to the bottom of the first moving plate 43, and a lifting cylinder 41 is fixed to the mounting plate 49. Two guide sleeves 46 are embedded in the first moving plate 43, and guide posts 47 pass through each of the two guide sleeves 46. The second moving plate 44 is fixed to the top of the two guide posts 47, and a connecting plate 48 is fixed to the bottom of the two guide posts 47. The piston rod of the lifting cylinder 41 is fixed to the connecting plate 48, and the lifting cylinder 41 drives the connecting plate 48, the guide posts 47, and the second moving plate 44 to move up and down relative to the first moving plate 43. A rotary cylinder 42 is fixed to the bottom of the second movable plate 44, and a plate-passing fixture 3 is located above the second movable plate 44. The output shaft of the rotary cylinder 42 passes through the second movable plate 44 and is fixed to the plate-passing fixture 3. The rotary cylinder 42 drives the plate-passing fixture 3 to rotate. Protective covers 410 are connected to both sides of the first movable plate 43. The protective covers 410 serve to prevent dust from entering the lower lifting cylinder 41 and the first movable cylinder.

[0028] In the above technical solutions: such as Figure 1 , 3 As shown, a second plate 82 is fixed on the frame 8, and the second plate 82 is located above the first plate 81. The pipe clamp drive mechanism 7 and the pipe clamp mechanism 5 are both located on the second plate 82, so that the pipe clamp drive mechanism 7 and the pipe clamp mechanism 5 are both located above the through-plate fixture 3. Figure 3As shown, the pipe clamp drive mechanism 7 includes a drive motor 71, a lead screw 72, a transmission seat, a fixed seat 75, and a third moving plate 73. The drive motor 71 and the fixed seat 75 are both fixed to the second platform 82. One end of the lead screw 72 is connected to the drive motor 71, and the other end is fixed to the fixed seat 75. The transmission seat is sleeved on the lead screw 72 and fixed to the bottom surface of the third moving plate 73. Two second slide rails 74 are fixed on the second platform 82, and each of the two second slide rails 74 has a second slider. The third moving plate 73 is fixed to the two second sliders. The pipe clamp mechanism 5 is mounted on the third moving plate 73. The drive motor 71 drives the lead screw 72 to rotate, thereby causing the transmission seat to move laterally relative to the lead screw 72, thus causing the third moving plate 73 and the pipe clamp mechanism 5 to move laterally.

[0029] In the above technical solutions: such as Figure 4 As shown, each set of pipe clamping mechanisms 5 includes a clamping cylinder 51, a push plate 54, and two clamping jaws 52. The clamping cylinder 51 is fixed to the third moving plate 73, and the piston rod of the clamping cylinder 51 is connected to the push plate 54. The tails of the two clamping jaws 52 are integrally formed with connecting rods 55, and each connecting rod 55 has an inclined moving groove 56. The end of the two moving grooves 56 near the push plate 54 is a closed end, and the end of the two moving grooves 56 away from the push plate 54 is an open end. Two bolts 57 are inserted through the end of the push plate 54. The ends of the two bolts 57 pass through the two moving grooves 56 respectively and are fitted with nuts. The end of the push plate 54 is slidably installed in the moving grooves 56 through the bolts 57, and the push plate 54 drives the bolts 57 to move within the moving grooves 56. Both clamping jaws 52 are hinged to the third moving plate 73 through hinge shafts 58, and each clamping jaw 52 has a clamping groove 53 on its opposite side.

[0030] The clamping cylinder 51 drives the push plate 54 to move forward. The push plate 54 drives the bolt 57 to move along the moving groove 56 from the closing end to the opening end. The linear motion of the push plate 54 is transmitted through the inclined moving groove 56 on the connecting rod 55, driving the two clamping jaws 52 to rotate and swing around their respective hinge axes 58, thereby opening the two clamping jaws 52 and lowering the tube bundle 2. The clamping cylinder 51 drives the push plate 54 to move backward, and the bolt 57 moves from the opening end to the closing end of the moving groove 56, thereby closing the two clamping jaws 52 and clamping the tube bundle 2. The clamping jaws 52 form a force-saving lever with the hinge axis 58 as the fulcrum, which can clamp the tube bundle 2 without causing excessive compression. The power output from the clamping cylinder 51 is used as the input force, acting on the power arm end of the lever, and the clamping jaws 52 act as the resistance arm end, clamping the workpiece. The power arm is longer than the resistance arm, which can amplify the force and ensure stable clamping. By integrating the connecting rod 55 with the gripping jaws 52, the synchronous opening and closing of the two gripping jaws 52 is ensured, achieving automatic centering and avoiding clamping misalignment. When the gripping position is reached, the connecting rod 55 and the hinge shaft 58 form a near-dead-point force transmission state. This not only amplifies the clamping force but also maintains the clamping state in the event of air interruption or pressure loss, providing a certain degree of mechanical self-locking capability and enhancing safety.

[0031] In the above technical solutions: such as Figure 1 As shown, the frame 8 is also equipped with four gripping buttons 76 connected to the controller 9. The four gripping buttons 76 respectively control the gripping cylinders 51 in the four sets of pipe clamping mechanisms 5 to drive the push plate 54 to move forward, so that the two gripping claws 52 close together to grip the pipe bundle 2. At the same time, the four gripping buttons 76 are respectively equipped with the same markings corresponding to the four sets of pipe clamping mechanisms 5.

[0032] In the above technical solutions: such as Figure 4 As shown, a third slide rail 59 and a limiting block 510 are also fixed on the third moving plate 73. A third slider 511 is slidably mounted on the third slide rail 59. The bottom of the push plate 54 is fixed on the third slider 511. The cooperation between the third slide rail 59 and the third slider 511 guides the movement of the push plate 54. Limiting grooves are provided on opposite sides of the two gripping jaws 52. When the two gripping jaws 52 are brought together, the limiting block 510 is located in the limiting groove of the two gripping jaws 52. The limiting block 510 limits the closing process of the two gripping jaws 52 to prevent the two gripping jaws 52 from over-gripping and damaging the tube bundle 2.

[0033] In the above technical solutions: such as Figure 3As shown, the system also includes a tube bundle positioning mechanism 6, which positions the tube bundles 2. The tube bundle positioning mechanism 6 includes a first positioning plate 63, a second positioning plate 64, a third positioning plate 65, and a fourth positioning plate 66 located at the top of the frame 8. These four positioning plates are all located above the tube clamping mechanism 5. The first positioning plate 63 and the second positioning plate 64 are arranged in parallel, as are the third positioning plate 65 and the fourth positioning plate 66. The ends of the four tube bundles 2 are in contact with the first positioning plate 63, the second positioning plate 64, the third positioning plate 65, and the fourth positioning plate 66, respectively. The tube bundle positioning mechanism 6 also includes a support plate 67 and four protrusions 68 located on the support plate 67. The support plate 67 is located below the tube clamping mechanism 5, and the four protrusions 68 are spaced apart and located directly below the midpoint of two gripping jaws 52 in the four sets of tube clamping mechanisms 5.

[0034] The tube bundle 2 is manually picked up and positioned between the clamping grooves 53 of the two clamping jaws 52 in the tube clamping mechanism 5, which are marked with the same designation. At this time, the clamping jaws 52 are in the open state. Simultaneously, one end of the tube bundle 2 is fitted onto the protrusion 68, positioning the tube bundle 2 at the clamping center of the tube clamping mechanism 5 (the midpoint between the two clamping grooves 53 after merging). The bottom of the tube bundle 2 is in contact with the top surface of the support plate 67, and the other end of the tube bundle 2 is in contact with the corresponding first positioning plate 63 / second positioning plate 64 / third positioning plate 65 / fourth positioning plate 66, thus positioning the tube bundle 2. Then, the clamping button 76 with the same designation is pressed, activating the clamping cylinder 51 to move the push plate 54 forward, causing the two clamping jaws 52 to close and clamp the tube bundle 2. The above operation is repeated four times to ensure that all four tube bundles 2 are positioned and clamped by their corresponding tube clamping mechanisms 5. The protruding post 68 and the support plate 67 position the clamping position of the tube bundle 2. The protruding post 68 is used to position the clamping center of the tube clamping mechanism 5 to prevent the tube bundle 2 from being squeezed by the clamping claw 52 due to deviation from the clamping center, which would cause the tube bundle 2 to deform or even break. The support plate 67 ensures that multiple tube bundles 2 are clamped at the same height by the tube clamping mechanism 5. At the same time, the support plate 67 supports the tube bundle 2 to prevent the tube bundle 2 from falling due to insufficient clamping force of the tube clamping mechanism 5.

[0035] In the above technical solutions: such as Figure 3As shown, the tube bundle positioning mechanism 6 also includes a first moving mechanism and a second moving mechanism fixed on the frame 8. The first moving mechanism includes a fifth moving cylinder 61 and a second moving cylinder 62. Both the fifth moving cylinder 61 and the second moving cylinder 62 are connected to the top of the frame 8 via mounting connecting plates. The piston rod of the fifth moving cylinder 61 is connected to the first positioning plate 63 and the second positioning plate 64 and drives the first positioning plate 63 and the second positioning plate 64 to move back and forth. The piston rod of the second moving cylinder 62 is connected to the third positioning plate 65 and the fourth positioning plate 66 and drives the third positioning plate 65 and the fourth positioning plate 66 to move up and down. The second moving mechanism includes a third moving cylinder 69 and a fourth moving cylinder 610. The third moving cylinder 69 is fixed to the frame 8. The piston rod of the third moving cylinder 69 is connected to the fourth moving cylinder 610. The piston rod of the fourth moving cylinder 610 is connected to the bottom of the support plate 67. The third moving cylinder 69 drives the fourth moving cylinder 610 and the support plate 67 to move up and down. The fourth moving cylinder 610 drives the support plate 67 to move laterally.

[0036] When all four tube bundles 2 are positioned and clamped by the corresponding tube clamping mechanism 5, the third moving cylinder 69 drives the support plate 67 and the protrusion 68 to move downward, so that the bottom of the tube bundle 2 is disengaged from the protrusion 68. The fourth moving cylinder 610 drives the support plate 67 and the protrusion 68 to move to the left. The fifth moving cylinder 61 drives the first positioning plate 63 and the second positioning plate 64 to move backward and disengage from the tube bundle 2. The second moving cylinder 62 drives the third positioning plate 65 and the fourth positioning plate 66 to move upward and disengage from the tube bundle 2, so that the tube bundle positioning mechanism 6 is separated from all the tube bundles 2, preventing the tube bundle positioning mechanism 6 from interfering with the assembly and movement process of the tube bundle 2 and interfering with the assembly of the tube bundle 2.

[0037] In the above technical solutions: such as Figure 2 As shown, the frame 8 is also equipped with an air source processing unit 14, which is used to supply compressed air to the cylinder. The air source processing unit 14 is a commercially available device. The frame 8 is also equipped with several cooling fans 10.

[0038] In the above technical solution: the frame 8 is also equipped with a start button 12 and a reset button 13 connected to the controller 9. Pressing the start button 12 starts the assembly operation, and pressing the reset button 13 resets each component to the initial state waiting for loading.

[0039] The working process of this invention is as follows: The controller 9 is turned on, the air source treatment unit 14 is connected to air at a pressure of approximately 0.4-0.5 MPa, the reset button 13 is pressed to ensure all components are reset in place, the guide plate 1 is manually placed on the guide plate fixture 3, so that the four pipe connectors 11 on the guide plate 1 are respectively fitted onto the four positioning posts 32, and the nut seat at the bottom of the guide plate 1 is located in the relief groove 31; the tube bundle 2 is manually removed, so that the tube bundle 2 is positioned between the clamping grooves 53 of the two clamping claws 52 in the tube clamping mechanism 5 with the same markings, at which point the clamping... With the gripper 52 in the open position, one end of the tube bundle 2 is simultaneously fitted onto the protrusion 68, and the other end of the tube bundle 2 contacts the corresponding first positioning plate 63 / second positioning plate 64 / third positioning plate 65 / fourth positioning plate 66, completing the positioning of the tube bundle 2. Next, press the gripping button 76 with the same marking, activating the gripping cylinder 51 to move the push plate 54 forward, causing the two gripping grippers 52 to close and grip the tube bundle 2, completing the tube loading. Repeat the tube loading operation four times to ensure that all four tube bundles 2 are positioned and gripped by their corresponding tube clamping mechanisms 5. Figure 1 As shown, Figure 1 This is the state before assembly after the material has been loaded.

[0040] The third moving cylinder 69 drives the support plate 67 and the protrusion 68 to move downward, so that the bottom of the tube bundle 2 is separated from the protrusion 68. The fourth moving cylinder 610 drives the support plate 67 and the protrusion 68 to move to the left. The fifth moving cylinder 61 drives the first positioning plate 63 and the second positioning plate 64 to move backward and separate from the tube bundle 2.
