Description

Technical Field

[0001] The utility model relates to a transfer trolley, in particular to a transfer trolley of a welding robot, belonging to the technical field of welding robots. Background Art

[0002] At present, the field of industrial robot welding mainly uses conventional medium and large welding robots. The size of this robot, the space for movement, and the space occupied by the robot control cabinet are relatively large. In addition, the robot itself weighs more than 150kg and can only be installed on a fixed base or a bottom mobile track, which greatly compresses the scope and location of the robot. The robot cannot enter the interior of some medium and large workpieces due to its size. Although the existing robots can increase their range of movement by adding external axes (ground rails, cantilever mechanisms), it also greatly increases their costs, making it difficult to meet customer needs.

[0003] When in use, existing conventional welding robots are usually fixed in a certain position, making it difficult to move the welding robots, and mechanical welding collaborative robots are difficult to separate from the mobile machine base. When welding the inside or edge welds of medium, large, and heavy welding workpieces, conventional medium and large robots cannot meet the welding requirements due to factors such as limited space and site. For this reason, we provide a welding robot transfer trolley to solve the above problems. Utility Model Content

[0024] The embodiment of the utility model provides a transfer trolley of a welding robot.

[0025] The components involved in this application are all prior art and will not be described in detail in this application.

[0026] See also Figure 1 , including a transfer trolley 1, a group of universal wheels 21 are fixedly installed on the bottom surface of the transfer trolley 1. Through the setting of the universal wheels 21, it is convenient for the staff to move the device to the position where welding is required, reducing the difficulty of the staff to move the welding robot.

[0027] See also Figure 1 and Figure 2 A small control cabinet 2 and a welding power supply 3 are fixedly installed on the top surface of the transfer trolley 1. The small control cabinet 2 can control the collaborative robot 6 and set the program of the collaborative robot 6, so that the collaborative robot 6 can perform welding operations according to actual needs. The welding power supply 3 provides power for the operation of various components of the device.

[0028] See also Figure 1A heat dissipation window 19 is provided on the outer surface of the welding power source 3. An operating tablet is installed on the welding power source 3. The staff can set and control the data of the welding power source 3 through the operating tablet. A heat dissipation fan is installed inside the heat dissipation window 19, which can dissipate the heat generated by the operation of the welding power source 3 to the outside of the device, so as to prevent the internal temperature of the welding power source 3 from being too high and affecting the normal operation of the device.

[0029] See also Figure 1 , Figure 2 and Figure 4 A collaborative robot 6 is arranged above the small control cabinet 2. A square base 7 is fixedly connected to the bottom of the collaborative robot 6. The square base 7 is made of Q235A material and 6mm or 8mm thick steel plate. The square base 7 and the collaborative robot 6 are insulated by an epoxy resin board to prevent current from passing through the square base 7 to damage the internal electrical appliances and also to avoid disrupting the welding current. There are two handles on the top surface of the square base 7 to facilitate the staff to move the collaborative robot 6 through the handles.

[0030] A set of magnetic chassis 8 are fixedly connected to the side surface where the square base 7 and the small control cabinet 2 are close to each other. The magnetic chassis 8 is equipped with right-angle sheet metal and reinforced magnets. Through the arrangement of four magnetic chassis 8, the collaborative robot 6 can be stably installed above the small control cabinet 2, thereby increasing the stability of the device. At the same time, the magnetic chassis 8 also makes it convenient for the staff to remove the collaborative robot 6 from the small control cabinet 2 and move it to a small space where welding is required.

[0031] The end of the collaborative robot 6 is rotatably connected to a connecting rod 9, and an electric welding gun 10 is fixedly connected to the outer surface of the connecting rod 9. The electric welding gun 10 is fixedly connected to a wire feeding tube 13. The collaborative robot 6 can rotate the connecting rod 9 to adjust the position of the electric welding gun 10 according to the actual welding position, so that the collaborative robot 6 can perform welding operations at various angles. The wire feeding tube 13 can provide welding wire for the welding operation of the electric welding gun 10.

[0032] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 A protective bracket 4 is fixedly connected to the top surface of the transfer trolley 1, and an auxiliary welding mixed gas storage tank 5 is arranged on the outside of the protective bracket 4. The protective bracket 4 can play a role in protecting various components of the device. The auxiliary welding mixed gas storage tank 5 can provide auxiliary gas for the welding operation of the collaborative robot 6, thereby improving the welding effect of the device.

[0033] The outer surface of the protection bracket 4 is fixedly connected with two groups of hanging blocks 17, and the inside of the hanging block 17 is hung with an iron chain 18. Both ends of the iron chain 18 are fixedly installed with hooks adapted to the hanging block 17. Through the arrangement of the hanging block 17 and the iron chain 18, the auxiliary welding mixed gas storage tank 5 can be protected, so that the auxiliary welding mixed gas storage tank 5 can be kept stable during the movement of the device.

[0034] See also Figure 1 and Figure 3 The outer surface of the protective bracket 4 is fixedly connected with an armrest 20, and the outer surface of the armrest 20 is covered with a layer of rubber pad, which can reduce the friction on the hands of the staff when pushing the device. The setting of the armrest 20 makes it convenient for the staff to move the transfer trolley 1.

[0035] See also Figure 2 and Figure 3 A baffle plate 11 is fixedly connected to the outer surface of the protective bracket 4, and the wire feeding tube 13 slides inside the baffle plate 11. When the collaborative robot 6 pulls the wire feeding tube 13 during operation, the wire feeding tube 13 will slide inside the baffle plate 11, thereby providing space for the collaborative robot 6 to operate. The baffle plate 11 plays a protective and supporting role, and can protect the components under the baffle plate 11 and provide support for the wire feeding tube 13 at the same time.

[0036] The outer surface of the welding power source 3 is rotatably connected to a winding roller 12, which can wind up the wire feeding tube 13 to prevent the wire feeding tube 13 from being scattered disorderly outside the device, affecting the movement and appearance of the device, and causing a certain degree of interference to the welding operation of the collaborative robot 6.

[0037] The outer surface of the welding power source 3 is fixedly connected with a support frame 15, which is adapted to the winding roller 12. The winding roller 12 can rotate on the support frame 15. The support frame 15 provides support for the rotation and winding operation of the winding roller 12 to prevent the winding roller 12 from sinking due to excessive gravity, thereby ensuring the normal winding operation of the winding roller 12.

[0038] A wire feeding tube 13 is wound around the outer surface of the winding roller 12, and a wire feeder 14 is fixedly installed inside the baffle plate 11. The wire feeding method and working principle of the wire feeder 14 are both prior arts and will not be described in detail in this application. The wire feeder 14 can provide the collaborative robot 6 with welding wire and can control the welding penetration and weld width by controlling the wire feeding speed of the welding wire, thereby achieving control of the welding quality. The welding wire provided by the wire feeder 14 is transported to the electric welding gun 10 via the wire feeding tube 13. The wire feeding tube 13 can protect the welding wire to prevent the welding wire from being cut by other substances during the welding process.

[0039] The top surface of the protective bracket 4 is fixedly connected with a connecting frame 16, which is slidably connected to the wire feeding tube 13. The connecting frame 16 provides support for the sliding of the wire feeding tube 13, so that the wire feeding tube 13 can remain stable during the sliding process, and avoids the wire feeding tube 13 from being scattered and piled up above the baffle 11 when sliding.

[0040] Working principle: When the staff uses the device for welding, they first push the transfer trolley 1 to a position suitable for welding through the winding roller 12, and then set the operating program of the collaborative robot 6 through the small control cabinet 2. The collaborative robot 6 starts to control the electric welding gun 10 to perform welding operations. At this time, the wire feeder 14 will transport the tin wire to the electric welding gun 10 through the wire feeding tube 13. When the staff wants to remove the collaborative robot 6 from the small control cabinet 2 for welding operations alone, they first remove the square base 7 from the small control cabinet 2 through the handle installed on the square base 7, and then move the collaborative robot 6 to a position suitable for the operation, which is convenient for moving the collaborative robot 6. At the same time, the collaborative robot 6 can also be disassembled from the transfer trolley 1, which is convenient for welding operations on the inside or edge welds of some medium, large, and heavy welding workpieces, thereby improving the applicability of the device.

[0041] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
