[0002] Copper busbar is copper busbar, which is an indispensable conductive material for manufacturing motor windings, high and low voltage electrical appliances, switch contacts, and wires for power distribution installation. It plays the role of transmitting current and connecting electrical equipment in the circuit. Copper busbar has been widely used in electrical equipment, especially complete sets of power distribution devices. However, there are many types of copper busbar products. Different types of products have different cross-sectional chamfers (such as right angles, rounded corners, etc.), different plating layers (such as tin plating, silver plating, etc.), different specifications and shapes (such as rectangles, cylinders, etc.), and the length of the copper busbar is generally very long. It is cut to the desired length and shape when it is used. The existing copper busbar handling equipment is usually designed for copper busbars of certain specifications to facilitate automatic handling. However, for copper busbar products of different models and specifications, such as copper busbars with larger width or smaller width, automatic handling cannot be achieved, and manual placement and storage are required. At the same time, due to the soft materials of small-width copper busbars and copper rods, they are very difficult to handle, storage and use are very inconvenient, and the labor intensity of workers is high, which affects the efficiency of subsequent production.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0026] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0027] like Figure 6 As shown, the structure of the tray 46 adapted by this solution is shown in the figure. The tray 46 is a U-shaped groove structure, which is suitable for accommodating small-sized copper bars and copper rods with a width not greater than 40 mm. The tray 46 is provided with a pair of lifting ears 47, and the number of the lifting ears 47 is multiple. The tray 46 can be taken and placed by hooking the lifting ears 47.

[0028] like Figures 1 to 5 As shown, a copper bar handling mechanism includes a sliding frame 513, on which a lifting mechanism is arranged, and a suction cup 534 for adsorbing the copper bar 1 and a hook mechanism 54 for hoisting the pallet 46 are connected to the lifting mechanism, and the interior of the suction cup 534 is negative pressure, and a hook 546 that can reciprocate and retract is arranged on the hook mechanism 54. Specifically, a vacuum pump 531 and a solenoid valve 532 are arranged on the sliding frame 513 to achieve the negative pressure effect in the suction cup 534. A vacuum sensor 535 for detecting the air pressure in the suction cup 534 is also included. Preferably, a distance sensor 55 for detecting the distance between the suction cup 534 and the copper bar 1 and / or the distance between the hook mechanism 54 and the pallet 46 is arranged on the sliding frame 513 to prevent the lifting mechanism from falling too far, causing the suction cup 534 and the hook mechanism 54 to collide with the copper bar 1 and the pallet 46, thereby avoiding damage to parts.

[0029] Specifically, the lifting mechanism includes a lifting motor 521, a connecting shaft 522, a lifting screw 523, a connecting seat 524 and a lifting connecting frame 525. The connecting shaft 522 is arranged in the horizontal direction. The lifting motor 521 drives the connecting shaft 522 to rotate. There are multiple lifting screws 523, and the lifting screws 523 are driven by the connecting shaft 522 to rotate and lift relative to the lifting screws 523. Specifically, both ends of the connecting shaft 522 are rotatably connected to the adapter seat. The lifting screw 523 is threadedly connected to the adapter seat, so that the rotation of the connecting shaft 522 drives the rotation of the lifting screw 523 [1]. The connecting seat 524 is fixedly connected to the bottom of the lifting screw 523. The lifting connecting frame 525 is fixedly connected to the bottom of the connecting seat 524 in the horizontal direction. The suction cup 534 and the hook mechanism 54 are connected to the lifting connecting frame 525. Since the copper bar 1 is relatively long, and the common length of the copper bar 1 is 6 meters, there are multiple suction cups 534, which are arranged in parallel in the horizontal direction to adsorb different positions of the copper bar 1 to ensure adsorption reliability. Preferably, multiple suction cups 534 are arranged on a connecting rod 533, and the connecting rod 533 is fixedly connected to the lifting mechanism. A buffer spring 536 is abutted between the suction cup 534 and the lifting mechanism. The buffer spring 536 makes the position of the suction cup 534 adapt to the copper bar 1 of different shapes, and at the same time protects the suction cup 534 from being subjected to a force exceeding the spring elastic force.

[0030] Preferably, the lifting mechanism further includes a lifting position sensor 526 for detecting the limit position of the lifting mechanism. The lifting position sensor 526 is arranged on the sliding frame 513 to detect the limit position of the lifting mechanism. The lifting position sensor 526 can be of various types such as a laser sensor.

[0031] like Figure 5 As shown, the hook mechanism 54 includes a hook fixing plate 541, which is fixedly connected to the lifting mechanism. A rotating cylinder 542 is installed on the hook fixing plate 541. A rotating gear 544 is coaxially fixedly connected to the lower part of the rotating cylinder 542 through a rotating shaft 543. The opposite sides of the rotating gear 544 are respectively meshed with a rack 545. The rack 545 is arranged parallel to the hook fixing plate 541 and slides relative to the hook fixing plate 541. The end of the rack 545 is connected to a hook 546. The rotating gear 544 is driven to rotate by the rotating cylinder 542, and the two racks 545 are driven to synchronously extend and retract relative to the hook fixing plate 541. After the rack 545 is extended, the hook 546 can be extended into the lifting ear 47. With the lifting action of the hook mechanism 54, the tray 46 can be taken and placed. There are multiple hook mechanisms 54, which are arranged corresponding to the number and position of the lifting ears 47, so that the tray 46 can be hooked from multiple points to ensure stable and reliable action. Preferably, the hook mechanism 54 also includes a rack detection sensor 547 for detecting the movement of the rack 545 relative to the hook fixing plate 541. The rack detection sensor 547 can be in the form of various sensors such as laser sensors to detect and feedback whether the rack 545 extends outward relative to the hook fixing plate 541.

[0032] like Figure 1 As shown, the fixed frame 511 is also included. The fixed frame 511 is perpendicular to the extension direction of the sliding frame 513 in the horizontal plane. The sliding frame 513 is slidably arranged on the fixed frame 511. The sliding frame 513 is provided with a driving mechanism, and the driving mechanism drives the sliding frame 513 to slide on the fixed frame 511. Specifically, the driving mechanism includes a sliding driving motor 514, a sliding driving shaft 515 and a sliding gear. The sliding driving shaft 515 is rotatably arranged on the sliding frame 513. A sliding rack 516 is fixedly arranged on the fixed frame 511 along the predetermined moving direction of the sliding frame 513. The sliding gear is fixedly connected to both ends of the sliding driving shaft 515. The sliding gear is meshed with the sliding rack 516. The sliding driving motor 514 drives the sliding driving shaft 515 and the sliding gear to rotate, thereby driving the sliding frame 513 to move along the fixed frame 511. The sliding frame 513 is rotatably provided with a roller 512 , and the roller 512 is provided on the fixed frame 511 and rolls along the fixed frame 511 to reduce the friction force when the sliding frame 513 slides.

[0033] When the copper bar transport mechanism is in operation, the driving mechanism drives the sliding frame 513 to slide along the fixed frame 511 to the predetermined material picking position, and the lifting mechanism drives the suction cup 534 and the hook mechanism 54 to fall. If the part to be transported is a large-sized copper bar 1, the suction cup 534 contacts the upper surface of the copper bar 1, and the vacuum pump 531 cooperates with the solenoid valve 532 to make the suction cup 534 negative pressure to complete the adsorption of the copper bar 1; if the part to be transported is a small-sized copper bar or copper rod, the hook mechanism 54 moves to the position of the ear 47, and the rotating cylinder 542 drives the rack 545 to extend outward until the hook 546 extends into the ear 47. After the material picking is completed, the lifting mechanism drives the suction cup 534 and the hook mechanism 54 to move upward, and the driving mechanism drives the sliding frame 513 to slide along the fixed frame 511 to the predetermined material discharge position, and the lifting mechanism drives the suction cup 534 and the hook mechanism 54 to fall. The vacuum pump 531 cooperates with the electromagnetic valve 532 to blow air outward from the suction cup 534 to separate the suction cup 534 from the copper bar 1, or the rotary cylinder 542 drives the rack 545 to retract inward to disengage the hook mechanism 54 from the lifting ear 47, thereby completing the material discharge action.
