Abstract
Description
Technical Field
[0001] This invention relates to the field of automotive roof manufacturing technology, and more particularly to a flexible welding line for automotive roof manufacturing. Background Technology
[0002] In the production of car roofs, plastic clips need to be welded onto the roof body. Currently, in traditional production processes, besides manual handling of the plastic clips and their hot-melt welding on a heating plate, semi-automatic mechanical devices with clamps are also used. However, current semi-automatic mechanical devices can only handle and weld clips in one direction. Therefore, a single clamp connected to a semi-automatic device can only hold one type of plastic clip and can only weld in one direction. When welding multiple different clips and multiple directions on a car roof, many semi-automatic welding devices are required, which not only significantly increases production costs but also means that a single welding station is typically only suitable for producing car roofs of one size and shape, resulting in poor adaptability. Furthermore, operators are required to assist the machine in clamping the clips, wasting manpower and resulting in extremely low efficiency.
[0003] If a semi-automatic mechanical device is used to clamp the plastic clips, the plastic clips need to be attached to the heating plate for heat melting. During the heat melting process, factors such as changes in the temperature of the heating plate can lead to over-melting, which will affect the welding quality.
[0004] Furthermore, when the existing clamps pick up the plastic clips, the plastic clips may sometimes shift due to factors such as the clamps not gripping them securely. Manually installing the clips can also easily result in misalignment, leading to product defects. Summary of the Invention
[0005] In order to overcome the shortcomings of the above-mentioned technologies, the purpose of this invention is to provide a flexible welding line for automobile roof production.
[0006] The technical solution adopted in this invention is: a flexible welding line for automobile roof production, comprising a workbench, multiple heating plates, and two fully automatic six-angle robotic arms. The two fully automatic six-angle robotic arms are arranged on both sides of the workbench. Each fully automatic six-angle robotic arm has a clamping frame on one side. The clamping frame includes a frame body, on which a tray and multiple clamps are arranged. Multiple plastic clips are arranged on the tray. Each clamp includes a connecting plate, a supporting body, a dual-axis cylinder, and a hook. The connecting plate and the supporting body are connected by multiple connecting columns. The lower part of the supporting body is provided with... The system includes a receiving groove and a first limiting groove. The first limiting groove is located below the receiving groove and is connected to it. A through groove is provided on the side of the supporting body, and the lower part of the through groove is connected to the receiving groove. The hook includes a vertical plate and a horizontal plate. The vertical plate passes through the through groove, and the horizontal plate passes through the receiving groove. One end of the vertical plate is fixedly connected to the horizontal plate, and the other end is fixedly connected to the push plate of the dual-axis cylinder. The cylinder body of the dual-axis cylinder is fixedly installed on the supporting body. There are a total of six heating plates. Three heating plates are installed on the left and right sides of the worktable, respectively. Two limiting plates are provided on the heating plate on the left side. The connecting plate is X-shaped.
[0007] Furthermore, two limiting plates are symmetrically arranged at both ends of the heating plate, and the limiting plates are vertically fixed to the heating plate.
[0008] Furthermore, a cone-shaped first limiting post is provided at each of the four corners below the connecting plate, and multiple X-shaped second limiting grooves are provided on the frame. The second limiting grooves are adapted to the connecting plate, and a first limiting hole is provided at each of the four corners of the second limiting groove. The first limiting hole is adapted to the first limiting post, and the first limiting post can be inserted into the corresponding first limiting hole. A rectangular through hole is provided in the middle of the second limiting groove.
[0009] Furthermore, the tray includes a rectangular tray body with multiple third limiting grooves, multiple conical second limiting posts at the bottom of the tray body, and multiple second limiting holes for inserting the second limiting posts on the frame body, with each second limiting hole corresponding to one second limiting post.
[0010] Furthermore, a handle is provided at each of the two ends of the upper part of the tray.
[0011] Compared with the prior art, the present invention has the following beneficial effects: The flexible welding line for automobile roof production described in this invention, with its fully automatic six-angle robotic arm, solves the difficulty of welding buckles of different angles on automobile roofs on the same machine; the fully automatic six-angle robotic arm connects to different clamps by adsorption, so that different clamps can grip different types of plastic buckles, and one fully automatic six-angle robotic arm can be used to move multiple types of plastic buckles, thus having a wider range of applications; the receiving groove of the clamp is adapted to the buckle body of the plastic buckle, and the limiting groove is adapted to the upper part of the welding plate, so that the plastic buckle is fixed and restricted in the bearing body, and will not be offset due to shaking during movement, ensuring accurate welding position and thus greatly reducing the occurrence of product defects; by setting the limiting plate, overheating is effectively prevented.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0023] like Figures 1 to 10As shown, a flexible welding line for automobile roof production includes a workbench 15, multiple heating plates 16, and two fully automatic six-angle robotic arms 17. The two fully automatic six-angle robotic arms 17 are positioned on either side of the workbench 15. Each fully automatic six-angle robotic arm 17 has a clamp frame 18 on one side. The clamp frame 18 includes a frame body 8, on which a tray 9 and multiple clamps 10 are mounted. The tray 9 has multiple plastic clips 7. Each clamp 10 includes a connecting plate 1, a supporting body 2, a dual-axis cylinder 3, and a hook 4. The connecting plate 1 and the supporting body 2 are connected by multiple... A connecting column 5 is connected. The lower part of the bearing body 2 is provided with a receiving groove 21 and a first limiting groove 22. The first limiting groove 22 is located below the receiving groove 21 and is connected to the receiving groove 21. The side of the bearing body 2 is provided with a through groove 23. The lower part of the through groove 23 is connected to the receiving groove 21. The hook 4 includes a vertical plate 41 and a horizontal plate 42. The vertical plate 41 passes through the through groove 23 and the horizontal plate 42 passes through the receiving groove 21. One end of the vertical plate 41 is fixedly connected to the horizontal plate 42, and the other end is fixedly connected to the push plate 31 of the dual-axis cylinder 3. The cylinder body 32 of the dual-axis cylinder 3 is fixedly installed on the bearing body 2.
[0024] There are six heating plates 16 in total. Three heating plates 16 are installed on the left and right sides of the workbench 15 respectively, and two limiting plates 19 are provided on the heating plate 16 on the left side.
[0025] Two limiting plates 17 are symmetrically arranged at both ends of the heating plate 16, and the limiting plate 19 is vertically fixedly connected to the heating plate 16.
[0026] The upper part of the bearing body 2 has a protrusion 24. When the clamp 10 holds the plastic buckle 7 and heats it to a set thickness on the heating plate 16, the bottom surfaces of both ends of the protrusion 24 contact the top surfaces of the two limiting plates 19 respectively, thereby preventing the plastic buckle 7 from being heat-melted further and avoiding over-melting.
[0027] The two fully automatic six-angle robotic arms 17 are symmetrically arranged on both sides of the worktable 15, and three heating plates 16 are arranged below each fully automatic six-angle robotic arm 17.
[0028] The connecting plate 1 is X-shaped, and a cone-shaped first limiting post 11 is provided at each of the four corners below the connecting plate 1. The frame 8 is provided with a plurality of X-shaped second limiting grooves 12, which are adapted to the connecting plate 1. Each second limiting groove 12 can be used to place a connecting plate 1 of a clamp 10. A first limiting hole 13 is provided at each of the four corners of the second limiting groove 12. The first limiting hole 13 is adapted to the first limiting post 11, and the first limiting post 11 can be inserted into the corresponding first limiting hole 13. A rectangular through hole 14 is provided in the middle of the second limiting groove 12, and the bearing body 2 can pass through the rectangular through hole 14.
[0029] The tray 9 includes a rectangular tray body 91 with multiple third limiting grooves 92. Each third limiting groove 92 can be used to place a plastic buckle 7. The bottom of the tray body 91 is provided with multiple conical second limiting posts 93. The frame 8 is provided with multiple second limiting holes 94 for inserting the second limiting posts 93. Each second limiting hole 94 corresponds to one second limiting post 93.
[0030] A handle 95 is provided at each of the two ends of the upper part of the tray 9. The second limiting post 93 cooperates with the second limiting hole 94 to ensure that the position of the tray 9 is fixed and to make the position of the plastic clips of the clamp more accurate. After the plastic clips of a car roof are welded, the worker removes the tray 9 and then directly replaces it with another tray 9 that carries the plastic clips 7, so that the welding of the next product can be carried out quickly, which greatly improves production efficiency.
[0031] The plastic buckle 7 is formed by connecting a buckle body 71 and a welding plate 72. Different models of plastic buckles 7 have different sizes and shapes of their buckle bodies 71 and welding plates 72. Each type of clamp 10 is used to clamp a specific model of plastic buckle 7, and each plastic buckle 7 has one or more corresponding clamps 10. The buckle body 71 of each plastic buckle 7 is adapted to the receiving groove 21 of its corresponding clamp 10, and the first limiting groove 22 of the corresponding clamp 10 is adapted to the upper part of the welding plate 72 of the plastic buckle 7.
[0032] Since different models of plastic buckles 7 have different sizes and shapes of buckle bodies 71 and welding plates 72, the third limiting grooves 92 on the tray 9 have various shapes. Each welding plate 72 has one or more third limiting grooves 92 that are adapted to it, so that the tray 9 can hold a variety of different models of plastic buckles 7.
[0033] There are four connecting posts 5 in total.
[0034] The vertical plate 41 and the horizontal plate 42 are vertically fixedly connected, and the vertical plate 41 and the horizontal plate 42 are integrally formed.
[0035] The dual-axis cylinder 3 is disposed between the bearing body 2 and the connecting plate 1.
[0036] The upper part of the connecting plate 1 is fixedly connected to the mother plate 6 of the quick-change plate, and the free end of the fully automatic six-angle robotic arm 17 is connected to the daughter plate of the quick-change plate. The daughter plate of the quick-change plate can be magnetically connected to the mother plate, so that the fully automatic six-angle robotic arm 17 can move the clamp 10 and the plastic buckle 7 through the quick-change plate under the program control of the control box.
[0037] In use, the car roof body is fixed on the workbench 15. The fully automatic six-angle robotic arm 17 first picks up the required clamp 10, and then moves the clamp 10 to position the carrier body 2 directly above the corresponding plastic buckle 7. The carrier body 2 is then lowered until the buckle body 71 is placed in the receiving groove 21, the upper part of the welding plate 72 is placed in the first limiting groove 22, and the lower part of the welding plate 72 is suspended outside the first limiting groove 22. Then, the push plate 31 of the dual-axis cylinder 3 drives the hook 4 to move towards the plastic buckle 7 until the horizontal plate 42 passes through the cavity of the buckle body 71 and presses against the side wall of the buckle body 71. Under the action of the hook 4, the upper part of the welding plate 72 is fixed in the first limiting groove 22, so that the plastic buckle 7 does not shift during transportation. The welding plate 72 is moved to the heating plate 16 for hot melting. After hot melting, it is welded to the car roof, thus ensuring accurate welding position.
[0038] The above embodiments are based on the technical solution of the present invention and provide detailed implementation methods and specific operation processes, but the protection scope of the present invention is not limited to the above embodiments.
