Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically a welding robot device. Background Technology

[0002] Air cushion conveyors are a new type of continuous material conveying equipment. Their core working principle is to use a blower to deliver compressed air to the air chamber inside the trough of the machine body. After the compressed air escapes through the vent or throttling hole at the top of the air chamber, it forms a uniform air cushion with a thickness of 0.1-0.5 mm between the conveyor belt and the bottom of the trough, which smoothly supports the conveyor belt and the material it carries. This transforms the rolling friction of traditional idlers into gas friction, greatly reducing running resistance and achieving low-friction, stable conveying. It is widely used in many industries such as coal, grain, power, and metallurgy.

[0003] As the core pressure-bearing component of the air cushion conveyor, the air chamber's structural integrity, sealing, and structural strength directly determine the stability of the air cushion formation and the reliability of equipment operation. It is usually composed of components such as discs, grooves, and base plates. Welding is a key process in the air chamber manufacturing process. Precise welding is required at the joints of each component to ensure that the welds are dense, free of slag inclusions, and free of defects such as porosity. This avoids problems such as air leakage and weld failure, ensuring that the air chamber can stably withstand the compressed air pressure, thereby ensuring the long-term efficient operation of the air cushion conveyor.

[0004] Currently, welding the air chamber of an air cushion conveyor requires operators to use handheld welding torches or semi-automatic welding equipment. This not only involves extremely high labor intensity, but also poses a serious health hazard to operators who work in high-temperature, strong light, fumes, and harmful gas environments for extended periods. Furthermore, the welding efficiency is low. In addition, existing welding methods suffer from inconvenient loading and unloading of materials. The air chamber components are mostly plate-shaped structures, which are large in size and weight, making it very difficult to move the air chamber on the processing table. Moreover, workpiece placement deviations are prone to occur during operation, affecting the subsequent welding accuracy. Summary of the Invention

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-6In this embodiment of the invention, a welding robot device includes two end frames 1. A second mounting frame 4 is fixedly connected between the lower ends of the two end frames 1. A first mounting frame 3 is provided above the end frames 1 and is fixedly connected to the end frames 1. An arc-shaped cover 8 is fixedly connected to the first mounting frame 3. A plurality of supporting arc plates 10 are fixedly connected to the upper surface of the arc-shaped cover 8. The arc-shaped cover 8 is provided with a support wheel assembly for facilitating the movement of the gas chamber. The support wheel assembly includes a plurality of rectangular slide rods 20. The plurality of rectangular slide rods 20 are slidably connected in the space formed between the supporting arc plates 10 of the arc-shaped cover 8. The plurality of rectangular slide rods 20 are evenly distributed in the middle and on both sides of the arc-shaped cover 8. The upper end of each rectangular slide rod 20 is rotatably connected to a first roller 11, and the lower end of each rectangular slide rod 20 is rotatably connected to a second roller 23. The lower end of each rectangular slide rod 20 is fixedly connected to a fixed plate 22. A spring 21 is sleeved on each rectangular slide rod 20 located between the fixed plate 22 and the arc-shaped cover 8. The second mounting frame 4 is provided with a pushing component for pushing the rectangular slide rod 20 upward. Multiple supporting arc plates 10 are provided to support the air chamber. The curvature of the supporting arc plates 10 is adapted to the curvature of the air chamber to ensure the stability of the air chamber after placement. The pushing component is used to lift the air chamber and detach it from the supporting arc plates 10 when feeding the air chamber, thereby facilitating the movement of the air chamber and making it convenient for loading and unloading.

[0026] The pushing assembly includes several bottom sliding arms 9. A second slide rail 24 is fixedly connected to both ends of the bottom sliding arms 9 in the second mounting frame 4. A first slide block 30 is fixedly connected to both ends of the bottom sliding arms 9, and the first slide block 30 is slidably connected to the second slide rail 24. A pushing component for cooperating with a second roller 23 is provided between the upper ends of the bottom sliding arms 9. The second mounting frame 4 also has a pushing mechanism for pushing the bottom sliding arms 9 along the second slide rail 24. The pushing component includes a longitudinal rod 29, which is fixedly connected between the bottom sliding arms 9 and located below the second roller 23. Several inclined protrusions 27 are fixedly connected to the longitudinal rod 29, and the inclined protrusions 27 cooperate with the second roller 23 to drive the first roller 11 upwards. The pushing mechanism includes a fixed crossbar. 26. The fixed crossbar 26 is fixedly connected inside the second mounting frame 4. The fixed crossbar 26 is fixedly connected to the third telescopic drive member 28. The output end of the third telescopic drive member 28 is fixedly connected to the bottom sliding arm 9. When the first roller 11 is pushed to move upward, the output end of the third telescopic drive member 28 moves the bottom sliding arm 9 along the second slide rail 24. The movement of the bottom sliding arm 9 synchronously moves the longitudinal rod 29. When the longitudinal rod 29 moves, the inclined protrusion 27 pushes the second roller 23 to move the rectangular slide rod 20 upward. The upward movement of the rectangular slide rod 20 will drive the first roller 11 to move upward. When it is necessary to drive the first roller 11 downward, the output end of the third telescopic drive member 28 resets to disengage the inclined protrusion 27 from the second roller 23. Then, the rectangular slide rod 20 resets downward under the action of the spring 21.

[0027] Several positioning rollers 5 are rotatably connected to both sides of the upper end face of the first mounting frame 3. A material blocking assembly is provided at one end of the first mounting frame 3. The material blocking assembly includes a first telescopic drive component 2, which is fixedly connected to one end of the second mounting frame 4. A connecting push rod 31 is fixedly connected to the output end of the first telescopic drive component 2. Positioning stops 33 are fixedly connected to both ends of the connecting push rod 31. The positioning stops 33 are slidably connected to the first mounting frame 3. When it is necessary to block the air chamber, the first telescopic drive component 2 can drive the connecting push rod 31 to move upward. The upward movement of the connecting push rod 31 drives the positioning stops 33 to move, thereby blocking the air chamber. When it is not necessary to block, the output end of the first telescopic drive component 2 drives the positioning stops 33 to reset downward.

[0028] The other end of the first mounting frame 3 is provided with a positioning component that cooperates with the baffle assembly to position the gas chamber. The positioning component includes a positioning push plate 19, which is rotatably connected to the end frame 1 on the side of the first mounting frame 3 away from the positioning baffle 33. The positioning push plates 19 are distributed on the end frame 1 above the first mounting frame 3. The tail of each positioning push plate 19 is fixedly connected to a drive arm 18. A rotating seat is fixedly connected to the first mounting frame 3 near the positioning push plate 19. A second telescopic drive member 7 is rotatably connected inside the rotating seat. The output end of the second telescopic drive member 7 is rotatably connected to the end of the drive arm 18 away from the positioning push plate 19. When positioning the gas chamber, the output end of the second telescopic drive member 7 moves to drive the drive arm 18 and the positioning push plate 19 to rotate around the pivot point, so that the positioning push plate 19 rotates to a position parallel to the support arc plate 10, thereby achieving the positioning of the gas chamber and ensuring the accuracy of the gas chamber position and the stability of subsequent welding.

[0029] A top frame 12 is fixedly connected to the upper ends of the end frame 1. First slide rails 17 are fixedly connected to both sides of the upper end of the top frame 12. Second slide blocks 32 are slidably connected to each of the first slide rails 17. A drive box 15 is fixedly connected between the two second slide blocks 32. A welding robot 16 for welding the gas chamber is mounted on the lower end of the drive box 15. The drive box 15 is equipped with a drive assembly for moving the drive box 15 along the first slide rails 17. The drive assembly includes a rack 13, which is fixedly connected to the top frame 12 near the center. A servo geared motor 14 is fixedly connected to the end of the servo geared motor 14, and a gear 25 is fixedly connected to the output end of the servo geared motor 14. The gear 25 meshes with the rack 13. The welding robot 16 can perform welding operations on the gas chamber according to a preset program during operation. At the same time, the servo geared motor 14 can drive the gear 25 to rotate. The gear 25 and the rack 13 work together to drive the drive box 15 to move. The movement of the drive box 15 drives the welding robot 16 to move, so that the welding robot 16 can move along the first slide rail 17 according to the preset program to complete the welding operation on the gas chamber.

[0030] A plurality of support legs 6 are fixedly connected between the first mounting frame 3 and the second mounting frame 4; the first telescopic drive component 2, the second telescopic drive component 7 and the third telescopic drive component 28 are cylinders, hydraulic cylinders or electric push rods.

[0031] The working principle of this invention is as follows: Before use, conveying devices are connected to both ends of the first mounting frame 3. During operation, the first telescopic drive 2 drives the connecting push rod 31 to move upward. The upward movement of the connecting push rod 31 drives the positioning stop 33 to form a limiting block. Then, the conveying device sends the air chamber between the two positioning push plates 19. At the same time, the output end of the third telescopic drive 28 moves the bottom sliding arm 9 along the second slide rail 24. The movement of the bottom sliding arm 9 synchronously drives the longitudinal rod 29 to move. When the longitudinal rod 29 moves, the inclined protrusion 27 pushes the second roller 23, causing the rectangular slide rod 20 to move upward. The upward movement of the rectangular slide rod 20 drives the first roller 11 to move upward, so that the sent air chamber contacts the first roller 11. Then, the operator pushes the air chamber so that the end of the air chamber hits the positioning stop 33. Subsequently, the output end of the second telescopic drive 7 moves the drive arm 18 and the positioning push plate 19 to rotate around the pivot point, so that the positioning push plate 19 rotates to the position of the supporting arc plate. The gas chamber is positioned parallel to the first slide rail 17. After positioning, the output end of the third telescopic drive 28 is reset, causing the inclined protrusion 27 to disengage from the second roller 23. Then, the rectangular slide bar 20 is reset downward under the action of the spring 21. At this time, the gas chamber falls onto the support arc plate 10 to complete the positioning operation. During welding, the welding robot 16 welds the gas chamber according to the preset program. At the same time, the servo reduction motor 14 can drive the gear 25 to rotate. The gear 25 cooperates with the rack 13 to drive the drive box 15 to move. The movement of the drive box 15 drives the welding robot 16 to move, which in turn allows the welding robot 16 to move along the first slide rail 17 according to the preset program to complete the welding operation of the gas chamber. After welding, the second telescopic drive 7 and the first telescopic drive 2 are reset, and the third telescopic drive 28 is activated again, causing the first roller 11 to rise. Then, the operator can slide the gas chamber from above the positioning stop bar 33 onto the discharge conveyor via the first roller 11.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Although this specification describes embodiments, not every embodiment contains only one technical solution. This method of description is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
