Technical Field
[0001] This utility model relates to the field of automated production line technology, specifically to an end-effector picking device and a single-arm handling robot. Background Technology
[0002] End-effectors are specialized tools at the end of industrial automation equipment (such as robotic arms, robots, or conveyor systems). They are typically installed at the end of industrial automation equipment to grip or move workpieces, quickly transfer workpieces or products, and reduce production cycle time.
[0003] In actual production, sometimes it is necessary to flip the workpiece during the handling process to meet the requirements of the next process. Using robots to flip the workpiece is a common method. However, due to the limitations of its own mechanical structure, the robot needs a large amount of space to move when performing the flipping operation, so it is not suitable for some confined spaces.

[0017] A single-arm handling robot includes a vertical beam and a large swing arm;
[0018] A slide plate is slidably mounted on the vertical beam, and a second driving component for driving the slide plate to move up and down is provided between the slide plate and the vertical beam;

[0023] The beneficial effects of this utility model are:
[0024] 1. The end-feed pickup device provided in this application embodiment can flip the workpiece during the transportation process. Since the workpiece is close to the axis of rotation when flipped, the required space is small and it can adapt to the working environment with limited space.

[0026] 3. The single-arm handling robot provided in this application embodiment also has the advantages of lightweight overall structure, compact structure, fast handling speed and low cost. Since the driving part for driving the first rotating shaft is set at the end of the connecting arm away from the first rotating shaft (i.e., the far end), the connecting arm can be designed to be thinner, thinner and lighter overall, and faster. It can replace the traditional robot to grasp small plates and is suitable for small and medium-sized plate production lines where the requirements for the trajectory of the handling work and the posture of the workpiece are not high.

A second driving component is disposed between the slide 42 and the vertical beam 41 to drive the slide 42 to move vertically relative to the vertical beam 41. A large swing arm 51 is mounted on the slide 42. The upstream end of the large swing arm 51 (with the end closer to the slide 42 as the upstream end) is rotatably connected to the slide 42. A third driving component 52 is disposed between the slide 42 and the large swing arm 51 to drive the large swing arm 51 to rotate relative to the slide 42.

A first synchronous belt 433 is disposed between the first driving pulley 431 and the first driven pulley 432. The slide plate 42 is detachably fixedly connected to the first synchronous belt 433.

The first pressure plate 422 is fixedly connected to the slide plate 42 by screws (not shown in the figure), and the first synchronous belt 433 is clamped and fixed between the first pressure plate 422 and the slide plate 42. A second drive motor 434 is disposed on the vertical beam 41, and the power output shaft of the second drive motor 434 is connected to the first driving pulley 431. For example, the first driving pulley 431 is located at the upper end of the vertical beam 41, the first driven pulley 432 is located at the lower end of the vertical beam 41, and correspondingly, the second drive motor 434 is located at the upper end of the vertical beam 41.

A mounting through hole for accommodating the reducer is provided on the upstream end of the large swing arm 51.
[0075] The fourth drive component 53 has the same structure as the third drive component 52, also including a reducer and a servo motor. The reducer in the fourth drive component 53 is also an RV reducer, and the connection relationship between the reducer and the servo motor in the fourth drive component 53 is the same as that in the third drive component 52. The difference between the fourth drive component 53 and the third drive component 52 is that the housing of the reducer in the fourth drive component 53 is detachably fixedly connected to the large swing arm 51, and the power output end of the reducer in the fourth drive component 53 is detachably connected to the mounting box 14 of the connecting arm 1. The downstream end of the large swing arm 51 is provided with a mounting through hole for accommodating the reducer of the fourth drive component 53.
[0076] The structure of the end-effector pickup device is the same as that of the end-effector pickup device described above, and will not be repeated here.
[0077] Furthermore, a balancing component is also provided on the vertical beam 41.
[0078] like Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, the balancing component includes a traction member 61 and a first support wheel 62 disposed on the upper end of the vertical beam 41. One end of the traction member 61 is detachably connected and fixed to the slide plate 42, and the other end of the traction member 61 extends from the top, around the first support wheel 62, to the side of the vertical beam 41 opposite to the slide plate 42. The side of the vertical beam 41 opposite to the slide plate 42 (according to...) Figure 5 The coordinate system shown is located on the rear side of the vertical beam 41. A balancing mechanism is provided. The balancing mechanism can apply an upward force to the slide plate 42 through the traction member 61, thereby balancing the weight of the slide plate 42 and the components installed on the slide plate 42, so as to reduce the load on the second drive motor 434.
[0079] In one specific embodiment, the balancing mechanism described in this example includes a sliding plate 631 located behind the vertical beam 41, capable of sliding up and down relative to the vertical beam 41, and a cylinder 632 for driving the sliding plate 631 to move up and down relative to the vertical beam 41.

The other end of the traction member 61 passes sequentially around the first support wheel 62 and the second support wheel 633 and is fixedly connected to the vertical beam 41 via a connecting frame 634, which is located above the sliding plate 631. Thus, the second support wheel 633, acting as a movable pulley, can reduce the stroke by half; that is, when the stroke of the slide plate 42 is L, the stroke of the sliding plate 631 is only 1 / 2L, thereby providing space for the installation of the cylinder 632.
[0080] In one specific embodiment, a cylinder 632 is respectively provided on the left and right sides of the traction member 61 between the slide plate 631 and the vertical beam 41.
