[0042] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0043] In the present invention, unless otherwise stated, the orientation terms such as "upper, lower, top, bottom" are usually in the direction shown in the drawings, or in the vertical, perpendicular or gravitational direction of the component itself; similarly, for the convenience of understanding and description, "inner, outer" refers to the inner and outer of the contour of each component itself, but the above orientation terms do not limit the present invention.

[0044] In order to solve the problems of low handling efficiency and large occupied space existing in the horizontal conveying device in the prior art.

[0045] An embodiment of the present invention provides a rotary table manipulator.

[0046] As Figures 1-9 shown, a rotary table manipulator provided by an embodiment of the present invention includes a rotary table 1, an indexing box 2, a mounting plate 3, a first slider 4, a plurality of load-carrying members 5 and a cam drive mechanism 6;

[0047] A plurality of linear guide rails 11 are arranged on the rotary table 1, the linear guide rails 11 extend along the radial direction of the rotary table 1, and the plurality of linear guide rails 11 are distributed along the circumferential direction of the rotary table 1.

[0048] The indexing box 2 includes a main shaft 21. The main shaft 21 passes through the turntable 1 and can drive the turntable 1 to pivot. The mounting plate 3 is arranged relative to the turntable 1 along the axial direction of the main shaft 21. An arc-shaped guide rail 31 is arranged on the mounting plate 3 along the circumferential direction of the main shaft. The arc-shaped guide rail 31 and a plurality of linear guide rails 11 are located between the turntable 1 and the mounting plate 3.

[0049] A second arc-shaped guide rail 41 is arranged on the first slider 4. When the first slider 4 is spliced with the mounting plate 3, the first arc-shaped guide rail 31 and the second arc-shaped guide rail 41 can be butted to form a circular guide rail.

[0050] Specifically, the mounting plate 3 is usually arranged in a circular shape and has a notch 32. The first slider 4 is inserted into the notch 32.

[0051] A plurality of load-carrying members 5. Each load-carrying member 5 is slidably arranged on one of the linear guide rails 11. The turntable 1 can pivot to enable the plurality of load-carrying members 5 to slide on the circular guide rail.

[0052] A cam driving mechanism 6. The main shaft 21 is in transmission cooperation with the first slider 4 through the cam driving mechanism 6. The main shaft 21 can drive the cam driving mechanism 6 to drive the first slider 4 to move along the radial direction of the circular guide rail.

[0053] It should be noted that when one of the plurality of load-carrying members 5 slides onto the second arc-shaped guide rail 41, the cam driving mechanism 6 drives the first slider 4 to move along the radial direction of the circular guide rail towards the outside of the circular guide rail.

[0054] With such an arrangement, when the main shaft 21 rotates, it cooperates with the timing of the cam driving mechanism 6. The turntable 1 rotates at a predetermined speed and drives the plurality of load-carrying members 5 to slide on the circular guide rail. When one of the plurality of load-carrying members reaches the second arc-shaped slide rail 41, the first slider 4 moves along the radial direction of the circular guide rail, so that the load-carrying member 5 located on the first slider 4 can move along the radial direction of the circular guide rail, and the workpiece 7 on the load-carrying member 5 is transported to a predetermined station, solving the problems of low handling efficiency and large occupied space existing in the horizontal conveying device in the prior art.

[0055] It can be understood that when the second arc-shaped slide rail 41 moves along the radial direction of the circular guide rail, it can be butted with the first arc-shaped slide rail 31 again to form the circular guide rail.

[0056] Further, the cam drive mechanism 6 includes a cam 61 and a drive shaft 62. The cam 61 is sleeved on the drive shaft 62, and the drive shaft 62 is used to drive the cam 61 to rotate. The drive shaft 62 is in transmission cooperation with the main shaft 21.

[0057] The cam drive mechanism 6 further includes a slide bar 63. The cam 61 is in transmission connection with the slide bar 63 through a transmission structure 64, and the first slider 4 is arranged on the slide bar 63.

[0058] Specifically, as shown in Figure 2 the transmission structure 64 includes a rocker 641 and a connecting rod 642. One end of the rocker 641 is pivotally connected to a fixedly arranged mounting shaft, and the other end is connected to one end of the connecting rod 642. The other end of the connecting rod 642 is connected to the slide bar 63. The cam drive mechanism is also provided with a cam follower, which is arranged between the two ends of the rocker 641. The cam follower is in close contact with the cam 61. When the cam 61 rotates, it can drive the rocker 641 to move, and the rocker 641 drives the connecting rod 642 connected thereto to move, so that the slide bar 63 slides back and forth along the Figure 2 vertical direction in the figure. When the slide bar 63 moves in the vertical direction, it can drive the first slider 4 to move, so that the first slider 4 can move along the radial direction of the circular guide rail.

[0059] Preferably, the circular guide rail is arranged as an arc-shaped groove, and the load-carrying member has a protruding portion, and the protruding portion is slidably arranged on the inner wall of the groove. With such a setting, through the cooperation between the protruding portion and the inner wall of the groove, the stability of the load-carrying member when sliding on the circular guide rail can be ensured.

[0060] Further, as shown in Figures 3-6 the load-carrying member 5 includes a connecting plate 51. The protruding portion is located on one side of the connecting plate 51. The connecting plate has another side opposite to the protruding portion, and a guide groove cooperating with the linear guide rail is arranged on the other side. With such a setting, the connecting plate 51 is located between the turntable 1 and the mounting plate 3. Moreover, the protruding portion on the connecting plate 51 is slidably arranged in the circular guide rail, and the guide groove of the connecting plate 51 is arranged on the linear guide rail. During the rotation of the turntable 1, the protruding portion slides in the circular guide rail, and the linear guide rail 11 plays a driving role on the load-carrying member, driving it to slide along the circular guide rail.

[0061] Further, the protruding portion includes a second slider 511 arranged on one side of the connecting plate, and the second slider 511 is slidably arranged on the inner wall of the circular guide rail.

[0062] Further, the load-carrying member 5 further includes a clamping unit 52. The connecting plate 51 has a first end away from the center of the circular guide rail. The clamping unit 52 is provided on the first end. The clamping unit includes a limiting mechanism 521 and an adsorption mechanism 522. The limiting mechanism 521 defines a clamping space, and the adsorption mechanism 522 is used to fix the workpiece 7 in the clamping space by adsorption.

[0063] Specifically, the limiting mechanism 521 includes two first limiting plates 5211 arranged oppositely and a second limiting plate 5212 arranged on one side of the two first limiting plates. The second limiting plate 5212 is perpendicular to the first limiting plate 5211, and the two first limiting plates 5211 and the second limiting plate 5212 enclose the clamping space.

[0064] Further, the limiting mechanism 5 may further include a bottom plate 5213. The first limiting plate 5211 and the second limiting plate 5212 are perpendicularly arranged on the bottom plate. The first limiting plate, the second limiting plate 1212 and the bottom plate jointly enclose the clamping space.

[0065] The adsorption mechanism 522 may be a vacuum adsorption mechanism and / or a magnetic adsorption mechanism.

[0066] When the mass of the adsorbed workpiece is relatively light, the adsorption mechanism may include a vacuum chuck, and the workpiece can be adsorbed and fixed in the clamping space through the vacuum chuck.

[0067] When the mass of the adsorbed workpiece is relatively heavy, the adsorption mechanism may include a negative pressure system, a vacuum chuck and / or a negative pressure port. The negative pressure system can generate negative pressure and communicate with the vacuum chuck and / or the negative pressure port, so as to be able to adsorb the heavier workpiece.

[0068] When the adsorbed workpiece is a magnetic substance, the adsorption mechanism can select a magnetic adsorption mechanism. The magnetic source of the magnetic adsorption mechanism can be arranged on the bottom plate, and the magnetic source can be a permanent magnet or an electromagnet.

[0069] Preferably, in this embodiment, at least one of the first limiting plates 5211 can move away from or towards the other relatively arranged first limiting plate 5211 in a direction perpendicular to the first limiting plate to adjust the size of the clamping space. With such a setting, the size of the clamping space can be adjusted to adapt to workpieces of different sizes.

[0070] An embodiment of the present invention further provides a stamping system, including a stamping device and the rotary table manipulator as described above. The main shaft of the stamping device is in transmission cooperation with the main shaft of the indexing box to drive the main shaft of the indexing box to rotate.

[0071] With such a setting, the main shaft of the indexing box can be driven by the main shaft of the stamping equipment. The stamping frequency of the stamping equipment is coordinated with the rotation of the main shaft of the indexing box and the timing of the cam, enabling the parts stamped by the stamping equipment to match the rotation speed of the main shaft of the indexing box. As a result, the load-bearing members arranged on the turntable can timely take away the processed workpieces. Moreover, the timing of the cam drive mechanism can control the sliding timing of the first slider, ensuring that when the turntable rotates the load-bearing member carrying the workpiece to the second arc-shaped slide rail on the first slider, the first slider is driven to move radially along the circular guide rail.

[0072] In summary, the embodiments of the present invention achieve the following technical effects:

[0073] With such a setting, when the main shaft rotates, it is coordinated with the timing of the cam mechanism. The turntable rotates at a predetermined speed and drives multiple load-bearing members to slide on the circular guide rail. When one of the multiple load-bearing members reaches the second arc-shaped slide rail, the first slider moves radially along the circular guide rail, enabling the load-bearing member located on the first slider to move radially along the circular guide rail and transporting the workpiece on the load-bearing member to a predetermined station, thus solving the problems of low handling efficiency and large space occupation existing in the horizontal conveying device in the prior art.
