Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen tank production, and in particular to a conveyor for an automated production line of hydrogen tanks. Background Art

[0002] Hydrogen tanks are the primary equipment for storing hydrogen and are crucial to its application. As a clean and efficient energy source, hydrogen has broad application prospects, including in transportation, industrial production, and power supply. The production of hydrogen tanks ensures the safe and efficient storage and supply of hydrogen, providing the necessary infrastructure for its application.

[0003] For example, the patent application with publication number CN117428658A discloses a weld polishing device for hydrogen storage tank layer wrapping, including a support base, an adjustment component and a hydrogen storage tank. The support base includes two straight rails and a polishing base. The polishing base is connected between the two straight rails. The upper surface of the polishing base is a concave arc surface. A plurality of through grooves are provided on the arc surface. Two groups of movable polishing boxes are connected in the plurality of through grooves. A single movable polishing box is provided with a plurality of grinding wheels evenly spaced inside, and the rotation radii of the plurality of grinding wheels do not intersect with each other; a driving roller is provided on the straight rail, and the driving roller is in contact with the hydrogen storage tank; an identification component is provided on the surface of the arc surface for identifying the presence of welds.

[0004] However, there are still some problems with the above patent. During the welding process, the above patent only fixes the extrusion section, while during the hydrogen tank molding process, the injection section needs to be placed on both sides of the extrusion section and welded at the same time so that the two injection sections can be welded on both sides of the extrusion section. Most of the existing injection sections include a hood-shaped head body and a head sealing tube arranged on the head body. Therefore, when carrying out the transportation work, the head body is mostly transported by a clamping robot that abuts against the outer wall of the head body and applies a certain pressure. However, since the head body is a hood-shaped structure, the head body will be deformed during the process of applying pressure to it, which will cause the head body to deform, and the deformed head body will not be able to be aligned with the extrusion section, which will lead to the failure of subsequent welding work.

[0005] Therefore, how to complete the transportation of the injection molding section is a problem that needs to be solved at present. Summary of the Invention

The moving supporting cylinder 21 can drive the supporting frame 22 to start working, and then the moving supporting frame 22 adjusts the penetration depth of the connecting frame 23, and adjusts the distance between the supporting wheel 24 and the top of the welding table 1 according to the size of the extruded section. Then the clamping cylinder 25 starts working. The moving clamping cylinder 25 can drive the limit frame 27 connected thereto to start working. The limit frame 27 moves along the third articulated seat 26 with the cooperation of the fifth connecting rod 212, so that the limit frame 27 abuts against the surface of the extruded section, and then the movable platform in the welding part 3 can adjust the position of the welding equipment. , so that the welding equipment completes the welding work of the extrusion section and the injection molding section. After completing the welding work at the predetermined position, the limit motor 28 starts to work, and the moving limit motor 28 can drive the gear box 29 to move. The moving gear box 29 can drive the connecting rod 210 to move, thereby driving the driving wheel 211 to rotate. Since the driving wheel 211 abuts against the surface of the extrusion section, the extrusion section can be rotated, so that the unwelded area on the extrusion section can be located in the welding area of the welding equipment, and the welding work is completed by the welding equipment; when the injection molding section is located on the support seat 551 under the transportation of the manipulator, the driving cylinder 553 starts to work at this time, and the moving driving cylinder 553 can drive the fourth connecting rod 554 to move, thereby moving The fourth connecting rod 554 can drive the transmission shaft 555 to rotate, and the rotating transmission shaft 555 drives the transmission member 556 to rotate, and then the rotating transmission member 556 drives the driving connecting rod 557 to move. When the transmission member 556 rotates clockwise, the driving connecting rod 557 can push the driven block 558 to move in the direction away from the transmission member 556. Conversely, the driving connecting rod 557 can push the driven block 558 to move in the direction close to the transmission member 556. When the transmission member 556 rotates clockwise, the moving driven block 558 can drive the supporting slider 5511 to move on the supporting slide rail 5510, thereby adjusting the position of the supporting block 559, so that the supporting block 559 abuts against the inner wall of the injection molding section, completing the limiting work of the injection molding section, and then With the movement of the linear motion mechanism 51, the transport seat 54 can be moved in the length direction of the limiting slide rail 52, so that the injection molding section on the transport seat 54 can be located in the clamping area of the second transport component 6, which is convenient for the clamping part 66 to clamp the injection molding section; when the clamping work is performed, the displacement motor 661 starts to work, and the moving displacement motor 661 can drive the driving gear 662 connected thereto to rotate, and then the rotating driving gear 662 can drive the driven gear 663 to rotate, thereby driving the adjusting screw rod 664 connected thereto to start moving, so that the adjusting disk 665 is located in the area surrounded by the injection molding section, and then the abutment block 6611 is abutted against the top of the sealing pipe mouth of the head, and the limiting wheel 6612 is provided through the internal support method,After the clamping work of the injection molding section is completed, the position of the abutment block 6611 and the limiting wheel 6612 is adjusted by moving the adjusting disk 665 on the adjusting screw 664, so that the abutment block 6611 abuts against the head sealing tube, and the limiting wheel 6612 passes through the head sealing tube and is located in the head body, and then the telescopic cylinder 666 starts to work. The moving telescopic cylinder 666 can drive the second articulated seat 667 to start moving, so that the first connecting rod 668 and the second articulated seat 667 have relative movement, and then the moving first connecting rod 668 drives the second connecting rod 669 to start moving, and the angle between the first connecting rod 668 and the second connecting rod 669 is adjusted so that the second connecting rod 668 and the second connecting rod 669 are relative movement. 69 rotates on the third connecting rod 6610, so that the limiting wheel 6612 abuts against the inner wall of the head body, completing the clamping work of the head, and then with the work of the adjusting member, completing the conveying work of the injection molding section, when the limiting wheel 6612 is located in the head body, at this time, the connection between the first connecting rod 668 and the second connecting rod 669 is at a predetermined distance from the inner wall of the head sealing tube, and then with the movement of the telescopic cylinder 666, the connection between the first connecting rod 668 and the second connecting rod 669 is away from the inner wall of the head sealing tube, ensuring that the first connecting rod 668 and the second connecting rod 669 can be expanded in the head sealing tube, so that the limiting wheel 6612 can abut against the connection between the head body and the head sealing tube, and then the transmission When the part 556 moves counterclockwise, the driving connecting rod 557 can push the driven block 558 to move in the direction close to the transmission part 556. At this time, the support block 559 is away from the injection molded part, so that the injection molded part is transferred from the first transport component 5 to the second transport component 6. Then, after completing the clamping work of the injection molding section, the limit mechanism 55 is away from the injection molding section, and then the adjustment motor 6532 starts to work. The moving adjustment motor 6532 can drive the transmission screw 6533 to start rotating, and then the moving transmission screw 6533 can adjust the position of the driving block 6534 in the length direction of the support 6531, so that the injection molding section is away from the transport platform 4, and then according to the size of the extrusion section, the adjustment The first rotating disk 651 starts to work, and the moving first rotating disk 651 can drive the support 6531 to rotate. Then the second rotating disk 654 starts to rotate, and the position of the injection section is adjusted. Through the cooperation of the first rotating disk 651 and the second rotating disk 654, the axis of the injection section and the axis of the extrusion section are coincident. Then the adjustment motor 6532 starts to work, and the position of the injection section on the support 6531 is adjusted, so that the injection section and the extrusion section are abutted. The injection section is then fixed to the extrusion section using welding equipment, completing the installation of the injection section, thereby completing the transportation and assembly of the hydrogen tank components.
