The existing single welding tooling has low welding efficiency, high labor intensity, complicated operation, and large product welding position accuracy error. According to the pneumatic battery bracket welding tooling described in patent number CN110948152A, manual precise positioning is required for loading, and unloading is required in advance before loading. Switching between loading and unloading in single-station operation mode takes a lot of time. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a manipulator pneumatic welding tool to solve the above-mentioned problems.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a manipulator pneumatic welding tool comprises a fixed base, the top of the fixed base is fixedly connected to a limiting frame, the top of the limiting frame is fixedly connected to a loading frame, the inner cavity of the loading frame is slidably connected to a sliding member through a sliding groove, one side of the sliding member is fixedly connected to a plurality of limiting plates through a connecting frame, a placement groove is separated from the sliding member by the plurality of limiting plates, the bottom of the sliding member is fixedly connected to a unloading channel communicated with the inner cavity of the placement groove, the bottom of the unloading channel is rotatably connected to a limiting rod driven by a cylinder, one side of the limiting frame is fixedly connected to a limiting block, the top of the limiting frame is fixedly connected to a clamping cylinder, the top of the clamping cylinder piston rod is fixedly connected to a clamping plate, the bottom of the limiting frame is fixedly connected to a workpiece lifting mechanism, and one side of the sliding member is fixedly connected to a pushing mechanism.

[0006] As a further solution of the present invention: an inner groove adapted to the surface of the workpiece is arranged in the middle of the top block, and a ball is rotatably connected to the inner cavity of the inner groove.

[0007] As a further solution of the present invention: the pushing mechanism includes a pushing plate fixed to one side of the sliding member, and a groove adapted to the surface of the workpiece is formed on one side of the pushing plate.

[0008] As a further solution of the present invention: the top of the push plate is fixedly connected to a push cylinder, the bottom end of the push cylinder piston rod is fixedly connected to a push rod, the push rod passes through and extends to the bottom of the push plate, and the surface of the push rod abuts against the surface of the workpiece.

[0009] As a further solution of the present invention: the length of the sliding member is one half of the loading rack, the sliding member is driven by a motor, and when the sliding member moves to the highest point, the unloading channel is located directly above the workpiece placement slot of the limiting rack.

[0012] When in use, the workpiece is placed on the sliding member, and the workpiece is placed in the sliding groove through the placement groove separated by the limit plate and the sliding member. The horizontal workpiece is directly placed in the gap between the upper and lower limit plates, and the vertical workpiece is placed under the connecting frame, in the gap between the limit plate and the sliding member. At this time, the limit rod driven by the cylinder blocks the lower part of the unloading channel, and the workpiece falls into the unloading channel and is blocked by the limit rod. Then the sliding member is driven by the motor to move upward in the loading frame. At this time, when the sliding member moves upward, the lifting cylinder at the bottom of the limit frame is lifted up, and the lifting cylinder drives the top block to move upward to push the workpiece to the top of the limit frame.

After the sliding part is transported to the top, the cylinder drives the limit rod to retract, and the limit on the unloading channel is lost. The workpiece falls from the unloading channel to the top of the limit frame, and then the clamping cylinder drives the clamping plate to rotate for limiting, and then the sliding part moves to the bottom for re-loading. After loading, repeat the above operation, eject the welded tooling, and then perform the unloading operation. When loading, you only need to place the workpiece above the sliding part, and it can be automatically positioned through the unloading channel. There is no need to stop and wait, and loading and unloading are carried out simultaneously. No additional power source is required, which not only improves the processing efficiency but also reduces energy consumption.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the present invention, when loading materials, it is only necessary to place the workpiece on the sliding part, and the workpiece can be automatically positioned through the unloading channel without stopping for waiting. The loading and unloading are carried out simultaneously, and no additional power source is required to drive it. It not only improves the processing efficiency and reduces the energy consumption, but also can directly shape the workpiece at one time, and can complete multiple synchronous processing steps in one clamping. One clamping avoids the size and position deviation caused by multiple clamping, optimizes the product processing accuracy, and ensures the product quality. By using this device, the transfer time of multiple workstations is saved, the labor efficiency is improved, and the labor intensity is reduced.

[0015] 2. In the present invention, when discharging, the downward pressure cylinder is started, and the workpiece is pressed downward by the downward pressure rod, so that the front end of the workpiece is tilted to prevent the front end from sinking. The workpiece is smoothly output to the buffer plate, buffered by the buffer plate, and then output through the guide wheel. The top of the workpiece can be kept upward during discharging, and the discharging is stable and not blocked. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The lifting mechanism includes a cylinder fixing frame 12 fixed at the bottom of the limit frame 2, and a lifting cylinder 13 is fixedly connected to one side of the cylinder fixing frame 12, and a top block 14 is fixedly connected to the top of the piston rod of the lifting cylinder 13. When loading, it is only necessary to place the workpiece above the sliding member 4, and it can be automatically positioned through the unloading channel 17 without stopping and waiting. The unloading and loading of materials are carried out simultaneously without the need for an additional power source to drive, which not only improves the processing efficiency but also reduces energy consumption.

[0027] An inner groove adapted to the surface of the workpiece is provided in the middle of the top block 14, and the inner cavity of the inner groove is rotatably connected with a ball 15. When the sliding member 4 moves upward, the lifting cylinder 13 at the bottom of the limit frame 2 is lifted up, and the lifting cylinder 13 drives the top block 14 to move upward to push the workpiece to the top of the limit frame 2. At this time, the workpiece is stuck in the inner groove of the top block 14 and rises upward.

[0028] The pushing mechanism includes a push plate 8 fixed on one side of the sliding member 4. A slot 9 adapted to the surface of the workpiece is opened on one side of the push plate 8. When the sliding member 4 moves, the push plate 8 is driven to move. The push plate 8 supports the workpiece through the slot 9 and pushes the workpiece to the discharge connection table 21.

[0029] The top of the push plate 8 is fixedly connected to a pressing cylinder 10, and the bottom end of the piston rod of the pressing cylinder 10 is fixedly connected to a pressing rod 11. The pressing rod 11 penetrates and extends to the bottom of the push plate 8, and the surface of the pressing rod 11 abuts against the surface of the workpiece. When discharging, the pressing cylinder 10 is started, and the workpiece is pressed downward by the pressing rod 11, so that the front end of the workpiece is tilted to prevent the front end from sinking. The workpiece is smoothly output to the buffer plate 22, buffered by the buffer plate 22, and then output through the guide wheel 23, which can keep the top of the workpiece upward during discharging, and the stable discharging is not blocked.

[0030] The length of the sliding member 4 is half of that of the loading rack 3 . The sliding member 4 is driven by a motor. When the sliding member 4 moves to the highest point, the unloading channel 17 is located directly above the workpiece placement slot of the limiting rack 2 .

[0031] A discharge connection platform 21 is fixedly connected to one side of the fixed base 1, a buffer plate 22 is fixedly connected to the top of the discharge connection platform 21, a guide wheel 23 is rollingly connected to the surface of the buffer plate 22, and shielding plates are fixedly connected to both sides of the discharge connection platform 21.

[0032] The loading rack 3 is flush with the surface of the limiting rack 2 .

[0033] When in use, the workpiece is placed on the slide 4, and the workpiece is placed in the sliding groove 5 through the placement groove separated by the limit plate 7 and the slide 4. The horizontal workpiece is directly placed in the gap between the upper and lower limit plates 7, and the vertical workpiece is placed under the connecting frame 6, in the gap between the limit plate 7 and the slide 4. At this time, the limit rod 16 driven by the cylinder blocks the lower part of the unloading channel 17, and the workpiece falls into the unloading channel 17 and is blocked by the limit rod 16. Then the slide 4 is driven by the motor to move upward in the loading frame 3. At this time, when the slide 4 moves upward, the jacking cylinder 13 at the bottom of the limit frame 2 is lifted up, and the jacking cylinder 13 drives the top block 14 to move upward to push the workpiece to the top of the limit frame 2. At this time, the workpiece is stuck in the inner groove of the top block 14 and rises upward. Then, when the slide 4 moves, it drives the push plate 8 to move, and the push plate 8 supports the workpiece through the slot 9 to push the workpiece to the unloading connection table 21. When discharging, start the downward pressure cylinder 10, and press the workpiece downward through the downward pressure rod 11, so that the front end of the workpiece is tilted to prevent the front end from sinking. The workpiece is smoothly output to the buffer plate 22, buffered by the buffer plate 22, and then output through the guide wheel 23. After the slide 4 is transported to the top, the cylinder drives the limit rod 16 to be retracted, and the limit on the unloading channel 17 is lost. The workpiece falls from the unloading channel 17 to the top of the limit frame 2, and then the clamping cylinder 18 drives the clamping plate 19 to rotate for limiting, and then the slide 4 moves to the bottom for re-loading. After loading is completed, repeat the above operation, push out the welded tooling, and then perform the unloading operation. When loading, you only need to place the workpiece above the slide 4, and it can be automatically positioned through the unloading channel 17, and there is no need to stop and wait. Unloading and loading are carried out simultaneously, and no additional power source is required. It not only improves the processing efficiency but also reduces energy consumption.
