[0002] Copper bus bars (or copper bars) are one of the main products in copper processing materials, with high mechanical properties, good electrical conductivity, thermal conductivity, excellent corrosion resistance, electroplating properties, brazing properties, beautiful metallic luster, and good forming and processing properties. They are indispensable conductive materials in the fields of manufacturing motor windings, high and low voltage electrical appliances, power transmission and transformation equipment, and wires for power supply and distribution installations. In recent years, with the continuous and rapid development of the national economy, the production and consumption of copper bars in China have also increased significantly.

[0003] At present, the production of copper bus bars mostly adopts a continuous extrusion process. The extruded copper bus bars are sheared according to product specifications, and the sheared copper bus bar products need to be transferred and stacked. Usually, for copper bus bar products with small width, thickness, and length and low weight, they can be manually carried and stacked, but the labor intensity is high and the labor cost is high; for copper bus bar products with large width, thickness, and length and high weight, the transfer and stacking of the sheared copper bus bar products need to be hoisted by a traveling crane (overhead crane), and the stacking efficiency is low, affecting the overall production efficiency of copper bars.

[0004] Therefore, there is an urgent need to design an automatic stacking machine device that can automatically carry and stack copper bus bars, and the automatic stacking machine also needs to be equipped with an automatic transmission device that can adjust the sheared copper bus bars to the grasping position of the stacking machine and hold them to facilitate the stacking machine to grasp the copper bus bars for stacking.

The support shaft connected to the movable end of the upper toggle arm is a short shaft, and the support shaft connected to the movable end of the lower toggle arm is a long shaft, so that the heights of the two rotating wheels are the same.

[0008] Optionally, the fixed ends of the two toggle arms are hinged on the first pin shaft through deep groove ball bearings.

[0009] Optionally, the two rotating wheels are nylon wheels made of nylon material.

[0010] Optionally, a coupling is connected to the telescopic end of the driving cylinder, and the rear ends of the two support plates are hinged to one end of the coupling away from the telescopic end through a second pin shaft.

[0023] The centering device for the copper busbar stacking machine according to the embodiment of the present utility model can be applied to the copper busbar conveying device equipped with the copper busbar stacking machine, and is used to center and adjust the position of the copper busbar on the conveying device, so that the position of the copper busbar matches the grasping position of the stacking machine, facilitating the accurate grasping of the copper busbar by the stacking machine. Specifically, the telescopic movement of the driving cylinder can drive the support plate 14 to move back and forth, and then drive the opening and closing of the two crank arms 3, thereby driving the two rotating wheels 2 to approach and move away from each other. In practical applications, the telescopic movement of the piston rod driven by the telescopic end can be adjusted by adjusting the compressed air volume in the two cavities of the cylinder. During the centering adjustment of the copper busbar position, the piston rod can drive the telescopic end to be in the retracted state, so that the two rotating wheels 2 tend to approach, thereby tending to clamp the copper busbar and adjust the copper busbar to the middle position of the conveying device.

[0024] The frame 13, crank arms 3, cylinder, etc. of the centering device are located below the copper busbar conveying surface of the conveying device (such as a roller conveying device), and the two rotating wheels 2 are located on the copper busbar conveying surface under the action of the support shaft, so that the two rotating wheels can correspondingly clamp the copper busbar during conveying. In an optional embodiment, a vertical first pin shaft 8 is provided at the rear end of the frame 13, and the fixed ends of the two crank arms 3 are laminated and hinged on the first pin shaft 8. The support shaft connected to the movable end of the upper crank arm 3 is a short shaft 11, and the support shaft connected to the movable end of the lower crank arm 3 is a long shaft 1, so that the heights of the two rotating wheels 2 are the same and are located on the copper busbar conveying surface. Among them, the bottom ends of the long shaft 1 and the short shaft 11 have threaded sections with smaller diameters, which can pass through the threaded holes at the movable ends of the two crank arms 3, and then cooperate with the round nut 12 to realize the connection between the two crank arms 3 and the long shaft 1 and the short shaft 11; the top ends of the long shaft 1 and the short shaft 11 have installation sections with smaller diameters that match the inner diameter of the rotating wheel 2, and cooperate with the first retaining ring 10 to realize the rotatable installation of the rotating wheel 2.

[0025] Optionally, deep groove ball bearings 9 are connected to the fixed ends of the two crank arms 3 and are hinged on the first pin shaft 8 through the deep groove ball bearings 9, and the connection is stable, reliable and convenient for rotation.

[0026] Optionally, the two rotating wheels 2 are nylon wheels made of nylon material. The nylon wheels have a certain rigidity, high wear resistance, long service life and low cost.

[0027] In this embodiment, a receiving member 15 is connected to the telescopic end of the driving cylinder 16. The rear ends of the two support plates 14 are hinged to one end of the receiving member 15 away from the telescopic end through a second pin shaft 17. The receiving member 15 is a connecting member between the telescopic end of the cylinder and the two support plates, and can be specifically set according to the shapes of the telescopic end of the cylinder and the connecting plate. Here, the two support plates 14 are laminated and hinged on the second pin shaft 17. The front end of the upper support plate 14 is hinged to the upper crank arm 3 through a third pin shaft 4, and the front end of the lower support plate 14 is hinged to the lower crank arm 3 through a third pin shaft 4.

[0028] The frame 13 is a frame type with openings on both the left and right sides, composed of four frame plates in the front, back, upper, and lower directions. The first pin shaft 8 is located inside the rear frame plate and is connected to the upper and lower frame plates. The front frame plate has a support hole that matches the driving cylinder 16. The upper and lower frame plates are provided with long limit holes. The second pin shaft 17 is a long pin shaft with a longer length, and both ends extend into or out of the long limit holes. Second retaining rings 18 can be provided at both ends of the second pin shaft 17 to limit the position of the second pin shaft. The long limit hole corresponds to the movement path of the second pin shaft 17, and is used to limit the front and rear movement stroke of the second pin shaft 17, that is, to limit the opening and closing amplitude of the two crank arms 3, thereby limiting the distance between the two runners 2, and can be applicable to copper busbar products of different widths.

[0029] In an actual application scenario, components such as the driving cylinder in the centering device of the copper busbar stacking machine according to the embodiment of the present utility model can all adopt devices with corresponding functions in the prior art. Components such as the frame, runner, crank arm, and support plate can be set according to the conveying device and the copper busbar product model equipped in the stacking machine in the actual working condition.
