Description

Technical Field

[0001] This utility model relates to the field of feeding platform technology, specifically to an alternating feeding platform for a welding workstation. Background Technology

[0002] The welding workstation feeding platform is a key component of the welding automation system. It is mainly used to transport the workpieces to be welded to the welding area and work with the welding equipment to complete continuous production. It is typically used in industrial scenarios that require high-precision positioning and efficient transportation, such as automobile manufacturing, aerospace and machining.

[0003] During the feeding process, the common feeding structure uses the extension and retraction of a telescopic cylinder to complete a single feeding operation within the cycle of reciprocating motion. Each feeding operation also includes two stages: material dropping and material picking. Therefore, the overall motion cycle is relatively long. When performing high-speed welding or spot welding operations, the welding time is often less than the overall material feeding time, which leads to a long welding waiting time. Therefore, it is necessary to design an interleaved feeding structure to improve feeding efficiency and thus shorten the waiting time. Utility Model Content

[0006] Preferably, the distance between the two sets of electric vacuum suction cups is equal to the horizontal straight-line distance from the welding loading conveyor to the bearing plate, and the material platform is symmetrically distributed on both sides of the welding loading conveyor.

[0008] Preferably, a rotating plate is rotatably connected to the upper end of the feed platform, and a stepper motor that drives the rotating plate to rotate is installed inside the rotating plate. Each rotating plate is provided with a pair of bearing plates.

[0009] Preferably, the drive assembly includes a servo motor and a threaded rod. The servo motor is fixed at the middle position on the outer side of the horizontal plate, and the threaded rod is rotatably connected inside the horizontal plate.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Please see Figure 1-4This utility model provides a technical solution: it includes a welding feeding conveyor frame 1, a conveying roller installed inside the welding feeding conveyor frame 1, material platforms 2 fixed on both sides of the welding feeding conveyor frame 1, a bearing plate 22 set on the material platform 2, a horizontal plate 3 installed above the welding feeding conveyor frame 1, an mounting plate 4 slidably connected to the horizontal plate 3 through a drive assembly, two sets of electric vacuum suction cups 5 installed at the bottom of the mounting plate 4, a telescopic cylinder 51 fixed on the mounting plate 4 to drive the electric vacuum suction cups 5 to rise and fall, a controller 6 installed on the outside of the horizontal plate 3, the distance between the two sets of electric vacuum suction cups 5 is equal to the horizontal straight-line distance from the welding feeding conveyor frame 1 to the bearing plate 22, the material platforms 2 are symmetrically distributed on both sides of the welding feeding conveyor frame 1, and support columns 31 are fixed at the four corners of the bottom of the horizontal plate 3, with the bottom of the support columns 31 fixed to the upper end of the material platform 2.

[0019] The drive assembly includes a servo motor 32 and a threaded rod 33. The servo motor 32 is fixed at the middle position of the outer side of the horizontal plate 3. The threaded rod 33 is rotatably connected inside the horizontal plate 3. The threaded rod 33 passes through the mounting plate 4 and is threadedly connected to the mounting plate 4. The end of the threaded rod 33 is fixed on the output end of the servo motor 32. Limiting blocks 41 are fixed on both sides of the mounting plate 4. Limiting grooves are opened on the inner side wall of the horizontal plate 3 at positions corresponding to the limiting blocks 41.

[0020] The upper end of the material platform 2 is rotatably connected to a rotating plate 21, and a stepper motor that drives the rotating plate 21 to rotate is installed inside. Each rotating plate 21 is provided with a pair of bearing plates 22.

[0021] Working principle: First, connect the entire device to an external power source. By sliding the mounting plate 3 within the horizontal plate, one pair of electric vacuum suction cups 5 can be aligned with the welding feeding conveyor 1, and the other pair can be aligned with the material platform 2 on different sides. Driven by the telescopic cylinder 51 and adsorbed by the electric vacuum suction cups 5, the material on the material platform 2 can be adsorbed. The electric vacuum suction cup 5 located above the welding feeding conveyor 1 releases the material, achieving the purpose of alternating material loading on both material platforms 2. The material picking and unloading are carried out simultaneously, avoiding the waiting caused by motion reset, and achieving more efficient material feeding. During this process, the drive of the output end of the servo motor 32 drives the threaded rod 33 to rotate, which realizes the reciprocating sliding of the mounting plate 4. After all the material on the inner bearing plate 22 of the material platform 2 is loaded, the rotation of the rotating plate 21 can rotate the outer bearing plate 22 to the inner side, increasing the continuity of material feeding and preventing excessively long waiting time due to material loading. The unloaded bearing plate 22 can be rotated to the outer side for material loading without affecting the normal material feeding operation.
