[0030] In order to enable those skilled in the art to better understand the technical solutions of the embodiments of the present utility model, the present utility model is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a feeding device for sheet metal parts, which mainly includes two parts: a turning component 2 and a gripper component 1.

[0033] The turning assembly 2 includes a frame 21 and a turning frame 22 rotatably mounted on the frame 21 . The turning frame 22 is provided with a plurality of bottom plates 23 spaced apart along the rotation axis of the turning frame 22 and a variable distance component 28 for controlling the plurality of bottom plates 23 to approach or separate from each other.

[0034] A suction cup 24 and a vacuum generator (not shown in the figure) connected to the suction cup 24 are provided on each bottom plate 23 . The vacuum generator is used to control the suction cup 24 to absorb or release the sheet metal part 29 .

[0035] The gripper assembly 1 includes a base plate 10 and a lifting component disposed on the base plate 10 . The lifting component is connected to a frame 21 and is used to drive the flip assembly 2 to move in a vertical direction.

[0036] When it is necessary to grab multiple sheet metal parts 29 placed at intervals, the lifting component of the gripper assembly 1 controls the flip assembly 2 to descend to the material picking position, and the variable distance component 28 controls the multiple bottom plates 23 to approach or separate from each other, so that each bottom plate 23 corresponds to a sheet metal part 29, and at the same time, the suction cup 24 on each bottom plate 23 sucks the sheet metal part 29, and then the variable distance component 28 adjusts the spacing of the multiple sheet metal parts 29 to the specified spacing, and finally controls the flip frame 22 to rotate and drive the multiple sheet metal parts 29 to rotate synchronously at a preset angle, so as to facilitate the subsequent loading of the sheet metal parts 29 into the material tray. It should be noted that the preset angle that the flip frame 22 rotates to drive the multiple sheet metal parts 29 to rotate synchronously can be 90 degrees or 180 degrees.

[0037] The flip frame 22 of the sheet metal feeding device provided in this embodiment is rotatably arranged on the frame 21, and each bottom plate 23 is provided with a suction cup 24 for adsorbing or releasing the sheet metal, and the variable distance component 28 on the flip frame 22 is used to control the multiple bottom plates 23 to approach or separate from each other. When the suction cup 24 on each bottom plate 23 adsorbs the sheet metal 29, the multiple bottom plates 23 can be controlled to approach or separate from each other through the variable distance component 28, and finally the flip frame 22 is controlled to flip. The feeding device realizes flipping and variable distance when the sheet metal 29 is collected instead of manual work, thereby improving the processing efficiency of the sheet metal 29.

[0038] like Figure 4 As shown, in some embodiments, the frame 21 is U-shaped as a whole, and includes a top plate 210 and a first side plate 211 and a second side plate 212 disposed at opposite ends of the top plate 210 .

[0039] The turning frame 22 is disposed between two side plates (a first side plate 211 and a second side plate 212), and the lifting component is connected to the top plate 210, and is used to drive the entire frame 21 to move in the vertical direction, thereby driving the lifting of the captured sheet metal part 29. The frame 21 has a simple structure and is easy to process.

[0040] Continue as Figure 4 As shown, in some embodiments, the flip assembly 2 further includes a rotating power component, and the rotating power component includes a first motor 26 , a rotating shaft 25 and a first transmission mechanism 27 .

[0041] A first end of the rotating shaft 25 is rotatably connected to the first side plate 211 , and a second end of the rotating shaft 25 is rotatably connected to the second side plate 212 .

[0042] The first motor 26 is fixed on the first side plate 211 and is connected to the rotating shaft 25 through the first transmission mechanism 27. The flip frame 22 is fixedly connected to the rotating shaft 25 and can rotate synchronously with the rotating shaft 25. The first motor 26 can control the rotating shaft 25 to rotate.

[0043] Preferably, the flip frame 22 of this embodiment can rotate 360 ​​degrees in the space surrounded by the two side plates and the top plate 210 .

[0044] Of course, in some other embodiments, the turning frame 22 can also be rotated by manual drive. For example, the first end of the rotating shaft 25 is connected to a handle, and the operator can rotate the rotating shaft 25 by holding the handle.

[0045] like Figure 5 and Figure 6 As shown, in some embodiments, the pitch-changing component 28 includes a pitch-changing worm 283, a second motor 281 and a pitch-changing slide assembly.

[0046] The variable pitch worm 283 is rotatably arranged on the turning frame 22 (only part of the structure is shown in the figure), and a plurality of first spiral tracks 2830, a plurality of second spiral tracks 2831 and a circular track 2832 are provided on the variable pitch worm 283. The plurality of first spiral tracks 2830 and the plurality of second spiral tracks 2831 are arranged at intervals along the axial direction of the variable pitch worm 283 and are located on both sides of the circular track 2832.

[0047] The rotation direction of the first spiral track 2830 is opposite to that of the second spiral track 2831 , and the axial direction of the variable pitch worm 283 is consistent with the direction of the rotation axis 25 of the turning frame 22 .

[0048] The second motor 281 is disposed on the flip frame 22 and is connected to the variable pitch worm 283 through the second transmission mechanism 282 to drive the variable pitch worm 283 to rotate.

[0049] The pitch-changing slide assembly includes a fixed slide 286 , a plurality of first pitch-changing slides 287 , and a plurality of second pitch-changing slides 288 .

[0050] The fixed slide plate 286 is located between the plurality of first spiral tracks 2830 and the plurality of second spiral tracks 2831 .

[0051] Each first variable pitch slide plate 287 corresponds to a first spiral track 2830 and is slidably connected to the corresponding first spiral track 2830. Each second variable pitch slide plate 288 corresponds to a second spiral track 2831 and is slidably connected to the corresponding second spiral track 2831. The fixed slide plate 286 is slidably disposed in the annular track 2832.

[0052] The fixed slide 286, multiple first pitch-changing slides 287 and multiple second pitch-changing slides 288 correspond to a base plate 23 respectively. In this way, by controlling the rotation of the pitch-changing worm 283, the first pitch-changing slide 287, the fixed slide 286 and the second pitch-changing slide 288 can be adjusted to approach or separate from each other, thereby controlling the multiple base plates 23 to approach or separate from each other.

[0053] Specifically, when the pitch-changing worm 283 rotates in a clockwise direction, the first pitch-changing slide 287, the fixed slide 286 and the second pitch-changing slide 288 approach each other; correspondingly, when the pitch-changing worm 283 rotates in a counterclockwise direction, the first pitch-changing slide 287, the fixed slide 286 and the second pitch-changing slide 288 separate from each other.

[0054] In some embodiments, a receiving cavity for accommodating the variable pitch worm 283 is provided in the flip frame 22. A first guide groove 2201 and a second guide groove 2202 are provided on the outer peripheral wall of the flip frame 22 at intervals along the axial direction of the variable pitch worm 283.

[0055] The first guide groove 2201 corresponds to the multiple first spiral tracks 2830 on the variable pitch worm 283 , and the second guide groove 2202 corresponds to the multiple second spiral tracks 2831 on the variable pitch worm 283 .

[0056] The first variable pitch slide 287 is provided with a first guide portion extending into the first guide groove 2201, and is slidably connected to the first spiral track 2830 through the first guide portion. The second variable pitch slide 288 is provided with a second guide portion extending into the second guide groove 2202, and is slidably connected to the second spiral track 2831 through the second guide portion. The fixed slide 286 is provided on the third guide portion extending into the annular track 2832.

[0057] like Figure 6As shown, each first variable pitch slide plate 287 corresponds to a first spiral track 2830, and the pitches of the plurality of first spiral tracks 2830 are different. Each second variable pitch slide plate 288 corresponds to a second spiral track 2831, and the pitches of the plurality of first spiral tracks 2831 are different. The pitches of the plurality of first spiral tracks 2830 and the plurality of second spiral tracks 2831 gradually decrease in the direction approaching the annular track 2832. At the same time, since the first spiral track 2830 and the second spiral track 2831 have opposite rotation directions, when the variable pitch worm 283 rotates, the first variable pitch slide plate 287, the fixed slide plate 286 and the second variable pitch slide plate 288 approach or separate from each other.

[0058] Continue as Figure 5 and Figure 6 As shown, in some embodiments, the flip frame 22 is further provided with linear guide rails 285 located on both sides of the variable pitch worm 283 and a plurality of sliders 284 located on the linear guide rails 285. The length direction of the linear guide rails 285 is consistent with the axial direction of the variable pitch worm 283. That is, each linear guide rail 285 is respectively provided with a plurality of sliders 284, and each slider 284 is respectively slidably disposed on the linear guide rail 285 and can move along the linear guide rail 285.

[0059] The number of sliders 284 on the linear guide rails 285 on both sides of the variable pitch worm 283 is the same. Each first variable pitch slide 287 and each second variable pitch slide 288 are respectively connected to a slider 284 on two linear guide rails 285, and the slider 284 slides along the linear guide rails 285 to ensure the directional movement of the variable pitch slide.

[0060] like Figure 3 As shown, in some embodiments, the lifting component in the gripper assembly 1 includes a cylinder 11 and a lifting plate 12 connected to the free end of the piston rod of the cylinder 11 .

[0061] The cylinder 11 is fixed on the base plate 10, and the lifting plate 12 is located below the base plate 10 and connected to the frame 21 in the flip assembly 2, for example, connected to the top plate 210 on the frame 21. The lifting and lowering of the entire flip assembly 2 can be controlled by controlling the extension and retraction of the piston rod of the cylinder 11. The lifting component has a simple structure and can quickly control the lifting and lowering of the entire flip assembly 2.

[0062] Furthermore, in some embodiments, the gripper assembly 1 includes a plurality of linear bearings 15 fixed on the base plate 10 and a guide shaft 13 passing through each linear bearing 15 .

[0063] A plurality of linear bearings 15 are respectively arranged vertically on the base plate 10. Through holes corresponding to the linear bearings 15 are provided on the base plate 10. One end of the guide shaft 13 is connected to the lifting plate 12, and the other end is connected to the fixing ring 14. The diameter of the fixing ring 14 is larger than the inner diameter of the linear bearing 15. When the gripper assembly 1 controls the flip assembly 2 to descend to a specified position, for example, when the suction cup 24 is about 5 mm away from the sheet metal part 29, the fixing ring 14 abuts against the linear bearing 15, thereby limiting the guide shaft 13 from coming out of the linear bearing 15.

[0064] The embodiment of the utility model further provides a processing system for a sheet metal part 29 , and the processing system includes a feeding device for a sheet metal part 29 as described in any one of the above embodiments.

[0065] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims.
