Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for welding robots, and in particular to a feeding structure for a welding robot. Background Technology

[0002] Welding robots mainly consist of two parts: the robot itself and the welding equipment. The robot comprises the robot body and the control cabinet (hardware and software). The welding equipment, taking arc welding and spot welding as examples, consists of the welding power source (including its control system), the wire feeder (for arc welding), and the welding torch (or clamp), among other components.

[0003] When welding robots weld workpieces, a feeding device is usually needed to deliver the workpieces to the welding table. Most current feeding devices use conveyor belts. However, after the conveyor belt has finished conveying, the staff still needs to manually pick up the workpieces from the conveyor belt and then put them back on. This is extremely inconvenient, requiring the staff to repeat the picking up and putting down of the workpieces. In addition, there is a risk of safety hazards due to human error during the putting down of the workpieces.

[0004] CN202121424667.6 discloses a feeding mechanism for an automatic welding machine, comprising a worktable, several support columns fixedly connected to the surface of the worktable, a first hydraulic pump fixedly connected to the surface of the support columns, a fixed plate fixedly connected to the extended end of the first hydraulic pump, a discharge port on the surface of the worktable, a discharge plate fixedly connected below the discharge port, a feeding box fixedly connected to the surface of the worktable, a feeding port on the top of the feeding box, a feeding plate fixedly connected above the feeding port, a groove on the side of the feeding box near the fixed plate, several second hydraulic pumps fixedly connected to the bottom of the feeding box, a placement plate fixedly connected to the extended end of the second hydraulic pumps, a telescopic mechanical claw fixedly connected to the inner side wall of the feeding box, a first hydraulic rod fixedly connected inside the feeding plate, and a lifting plate fixedly connected to the extended end of the first hydraulic rod. This utility model achieves the fixing and automatic collection of welded workpieces through the coordinated operation of the mechanisms. However, this is a swing-type structure; a rotating disc structure would be more efficient. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The welding robot feeding structure shown in this embodiment includes: a platform 1, a welding table 2 fixedly installed on the top of the platform 1 near the right side, and a motor 4 fixedly installed on the top of the platform 1 near the left side. A disc 3 is fixedly installed at the power output end of the motor 4. A support component is provided at the bottom of the disc 3, and a fixed seat 12 is fixedly installed at the center of the top of the disc 3. The fixed seat 12 is a regular hexagon (it can also be a pentagon, octagon or even a decagon, so that there are more places to place the weldment when rotating). Electric push rods 13 are fixedly installed on all six sides of the outer wall of the fixed seat 12, for a total of six push rods. A connecting block 15 is fixedly installed at the telescopic end of the electric push rod 13. A movable plate 16 is fixedly installed at the bottom of the connecting block 15. The movable plate 16 is movably connected to the top of the disc 3, and a placement groove 17 is opened on the movable plate 16.

[0031] Specifically, multiple workpieces to be welded are placed inside multiple placement slots 17. During welding, the motor 4 drives the disc 3 to rotate. After the disc 3 rotates the workpiece to the welding table 2, the motor 4 is turned off and the electric push rod 13 at the corresponding position is driven. The electric push rod 13 pushes the connecting block 15 to move. The connecting block 15 drives the movable plate 16 to move. The movable plate 16 moves the workpiece inside the placement slot 17 to the surface of the welding table 2, so that the workpiece falls directly from the placement slot 17. Subsequently, the welding robot is used to weld the workpiece on the surface of the welding table 2. The operation is convenient.

[0032] In this embodiment, as Figures 4-5 As shown; a sliding plate 21 is movably installed at the bottom of the movable plate 16, and multiple slots 10 are opened at the top of the disc 3. Each of the multiple slots 10 has a sliding groove 11 on its inner wall, and the sliding plate 21 is slidably connected to the inner cavity of the sliding groove 11.

[0033] Specifically, when the electric push rod 13 pushes the movable plate 16 to move, the movable plate 16 drives the bottom slide plate 21 to slide inside the slide groove 11, thereby limiting the horizontal movement trajectory of the movable plate 16 and other components and improving stability.

[0034] In this embodiment, as Figure 5 As shown; one side of the slide plate 21 extends into the inner cavity of the slot 10, and two blocks 22 are fixedly installed on both sides of the outer wall of the slide plate 21, and the two blocks 22 are slidably connected to the inner cavity of the slot 10.

[0035] Specifically, when the slide plate 21 moves, it will cause the two outer blocks 22 to slide inside the slot 10. When the blocks 22 move to fit against the inner wall of the slot 10, the slide plate 21 can no longer move. If the movable plate 16 continues to move at this time, the slide plate 21 will not be able to support the welding parts placed inside the placement slot 17.

[0036] The slide plate 21 is located at the bottom of the movable plate 16 and can provide support for the bottom of the weldment placed inside the placement slot 17. When the slide plate 21 gradually becomes misaligned with the bottom of the placement slot 17, the weldment inside the placement slot 17 will fall directly out of the placement slot 17 and onto the surface of the welding table 2, which facilitates subsequent welding operations.

[0037] In this embodiment, as Figure 5 As shown; a horizontal block 19 is fixedly connected to the top of the slide plate 21, and a horizontal groove 18 is provided on the movable plate 16. The horizontal block 19 is slidably connected to the inner cavity of the horizontal groove 18, and a spring 20 is fixedly connected between the outer wall of the horizontal block 19 and the inner wall of the horizontal groove 18.

[0038] Specifically, when the movable plate 16 moves, since a spring 20 is installed between the movable plate 16 and the slide plate 21, the movable plate 16 will drive the slide plate 21 to move synchronously. However, when the two locking blocks 22 on the slide plate 21 are engaged inside the locking slot 10, if the movable plate 16 continues to move, the spring 20 will be compressed under the action of the cross block 19. After the weldment falls from the placement slot 17, the electric push rod 13 drives the movable plate 16 to reset, and the slide plate 21 will also gradually reset under the elastic force of the spring 20.

[0039] In this embodiment, as Figure 5 As shown; each of the multiple electric push rods 13 has a base 14 fixedly installed at its bottom, and the multiple bases 14 are respectively fixedly connected to the outer wall of the fixed seat 12.

[0040] Specifically, the base 14 is used to reinforce the connection between the electric push rod 13 and the outer wall of the fixed seat 12, thereby improving the stability of the electric push rod 13 during subsequent operation.

[0041] In this embodiment, as Figure 3As shown; the support assembly includes four cylinders 9, all of which are fixedly connected to the top of the platform 1, and each of the four cylinders 9 has a movably mounted block 7 on its top. An annular groove 6 is provided on the bottom of the disc 3, and the four blocks 7 are slidably connected to the inner cavity of the annular groove 6.

[0042] Specifically, the cylinder 9 and the block 7 work together to support the bottom of the disk 3, and the block 7 is slidably connected inside the annular groove 6, so it does not affect the rotation of the disk 3.

[0043] In this embodiment, as Figure 3 As shown; each of the four cylinders 9 has a circular shaft 8 fixedly installed on its top, and the top of the circular shaft 8 passes through the circular block 7 and is rotatably connected to the circular block 7.

[0044] Specifically, this setting enables the circular block 7 to rotate around the circular shaft 8, further stabilizing the sliding of the circular block 7 within the annular groove 6.

[0045] In this embodiment, as Figure 3 As shown; a fixing ring 5 is fixedly installed on the outer wall of the motor 4, and the fixing ring 5 is fixedly installed on the top of the platform 1.

[0046] Specifically, this setting reinforces the installation of motor 4 and improves its stability.

[0047] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0048] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
