Description

Technical Field

[0001] The invention belongs to the technical field of welding, and in particular relates to a copper soft connection welding device. Background Art

[0002] Copper flexible connection is a widely used connection method for high current conductors. Its characteristics are that it can improve conductivity and can also correct errors during equipment installation. Copper flexible connection is widely used in the production and manufacturing of transformers, high and low voltage switchgear, generators, mining explosion-proof switches, automobiles and other products. Among them, copper foil flexible connection is one of the common forms of copper flexible connection. The manufacturing method of copper foil flexible connection is to stack multiple layers of copper foil neatly together, use a polymer diffusion welding machine to melt and weld the two ends of the copper foil together, and finally silver-plate both ends to improve its corrosion resistance and conductivity.

[0003] When welding copper flexible connectors, it is necessary to place neatly stacked copper foil sheets on the welding table of the welding machine and remove them after welding is completed. In the prior art, many loading and unloading operations for copper flexible connectors are done manually. For example, the technical document of the Chinese patent publication number CN206028991U, entitled Welding Device for Copper Strip Flexible Connectors, discloses a welding device for copper strip flexible connectors, including a frame, a base provided on the frame, and a lower electrode, a lower cooling body, and a lower heating body provided on the base in sequence from bottom to top, and a drive assembly provided above the base. During welding, the operator is required to manually load and unload materials and control the welding device to complete the welding. This production method has low production efficiency.

[0052] Compared with the prior art, the copper soft connection welding device provided by the embodiment of the present invention has the following beneficial effects:

[0053] A copper soft connection welding device provided by an embodiment of the present invention includes a welding machine 10, a chain plate conveyor 20, a plurality of loading units 30, a cooling water pool 40 and a transfer manipulator 50. A limiting space for carrying and limiting a copper foil 100 is formed on the loading unit 30 by a railing 32. The neatly stacked copper foil 100 is transported to a welding assembly by the chain plate conveyor 20 together with the loading unit 30. When the transfer manipulator 50 reaches the grabbing position, the railing 32 shrinks to the inside of the positioning part 31, and the transfer manipulator 50 can transfer the stacked copper foil 100 from the loading unit 30 to the welding machine 10, and two welding machines 10 are used to weld the two ends of the copper foil 100 respectively. After welding is completed, the transfer manipulator 50 transfers the workpiece to the top of the cooling water pool 40, and the transfer manipulator 50 releases the product, and the product falls into the cooling water pool 40 for cooling. In this way, the automatic loading and unloading of the copper foil 100 can be completed without worrying about the risk of scalding of personnel, and the welding work efficiency and welding safety are improved.

[0054] The welding assembly includes two welding machines 10, which are specifically polymer diffusion welding machines, and are commonly used equipment for welding copper soft connections. There is no restriction on the specific specifications and models, and users can select and set them according to their needs.

[0055] A plurality of loading units 30 are arranged at equal intervals on the conveying chain plate of the chain plate conveyor 20, and can be connected and fixed by fasteners such as screws. Figure 1 The second horizontal movement shown can automatically transport the copper foil 100 to the grabbing position of the transfer robot 50 , and cooperate with the transfer robot 50 to complete automatic loading.

[0056] The chain plate conveyor 20 can drive multiple loading units 30 to circulate and realize continuous feeding. At the loading end of the chain plate conveyor 20, multiple copper foils 100 can be stacked on the corresponding loading platform manually, or a robot can be used to stack the copper foils 100.

[0057] The loading unit 30 includes a loading platform and a railing 32. The loading surface size of the loading platform corresponds to the size of the copper foil 100. A plurality of railings 32 are arranged around the loading surface. The railings 32 can be driven up and down by a cylinder or an electric lifting rod. The railings 32 are used to limit the position of the copper foil 100 during the transportation of the copper foil 100 to prevent the copper foil 100 from being offset due to vibration or shaking. In order to prevent the railings 32 from affecting the transfer robot 50 to grasp the copper foil 100, when the loading unit 30 moves to the unloading position of the transfer robot 50, the railings 32 are lowered and retracted into the positioning part 31, and will not interfere with the grasping of the transfer robot 50. The moving position of the loading unit 30 can be accurately monitored by a limit switch, a distance sensor, etc.

[0058] The cooling water pool 40 is arranged at the discharge side of the welding machine 10. There is cooling water inside the cooling water pool 40. After welding, the workpiece falls into the cooling water pool 40 for cooling. After cooling, the workpiece is taken out by the staff. The transfer manipulator 50 can grab and release the copper foil 100. The existing manipulator structure on the market can be directly selected to complete the grabbing and releasing of the copper foil 100 or other plate-shaped / sheet-shaped materials.

The clamping rod 52 and the mounting frame 51 are slidably matched in the second horizontal direction. When the transfer robot 50 clamps the copper foil 100 from the loading platform, the clamping rod 52 is accommodated in the corresponding avoidance groove 33; a first driving member 53 is arranged on the mounting frame 51, and is used to drive the clamping rod 52 to extend or contract. When the transfer robot 50 is in a clamping state, the clamping rod 52 extends, and when the transfer robot 50 is in a released state, the clamping rod 52 contracts, so that the welded workpiece falls from below; a pressing plate 54 is arranged on the mounting frame 51 and is located above the clamping rod 52. The pressing plate 54 can move up and down, and a clamping space for the copper foil 100 is formed between the pressing plate 54 and the clamping rod 52; a translation mechanism 55 is used to drive the mounting frame 51 to move between the loading unit 30, the welding machine 10 and the cooling water pool 40.

[0060] In this embodiment, the mounting frame 51 is used to support the first driving member 53, the clamping rod 52, the pressing plate 54 and other components. When clamping the copper foil 100, the clamping rod 52 extends into the avoidance groove 33 to lift the copper foil 100 from the bottom, and then the pressing plate 54 moves downward to apply pressure to the copper foil 100 from the top.

[0062] In this embodiment, the magnetic suction plate 541 can be a magnet or an iron component that can be attracted by the electromagnetic suction cup 60. When the mounting frame 51 moves to the bottom of the electromagnetic suction cup 60, the electromagnetic suction cup 60 is powered on to generate a magnetic suction force to suck the pressing plate 54 upward, so that the copper foil 100 can enter between the pressing plate 54 and the clamping rod 52. Then, the electromagnetic suction cup 60 is powered off to eliminate the magnetic force. Under the action of the preload force of the first elastic member, the pressing plate 54 can press the copper foil 100 downward. The first elastic member and the second elastic member 9321 mentioned below can be specifically springs.

[0063] Optionally, the translation mechanism 55 is an electric telescopic rod, a telescopic cylinder or a hydraulic push rod arranged along the second horizontal direction.
