DETAILED DESCRIPTION

[0040] 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.

[0042] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a transfer device for sheet metal parts, which mainly includes a fixed frame 1, a flip cache component 2 and a transfer component 3.

[0043] The flipping and caching assembly 2 is disposed on the fixed frame 1 . The flipping and caching assembly 2 includes a flipping component, and the flipping component includes a rotating shaft 23 rotatably disposed on the fixed frame 1 and a rotating carrier assembly disposed on the rotating shaft 23 .

[0044] The rotating carrier assembly includes at least one carrier plate. The carrier plate is provided with a positioning pin 211, a suction cup 210 and a vacuum generator (not shown in the figure) for controlling the suction or release of the suction cup 210. Figure 5 shown.

[0045] The sheet metal part 4 is provided with a positioning hole for inserting the positioning pin 211 , and the vacuum generator can control the suction cup 210 to absorb the sheet metal part 4 , thereby fixing the sheet metal part 4 on the carrying plate.

[0046] The transfer assembly 3 is located below the rotating shaft 23. The transfer assembly 3 includes a material receiving carrier 33, a lifting assembly 32 for controlling the lifting of the material receiving carrier 33, and a driving component 31 for controlling the lifting assembly 32 to move in a horizontal direction.

[0047] After the rotating shaft 23 rotates by a preset angle, the raised receiving carrier 33 can be opposite to the carrying plate, and the receiving carrier 33 is used to receive the sheet metal part 4 released by the carrying plate. Specifically, the vacuum generator can control the suction cup 210 to release the sheet metal part 4, and the sheet metal part 4 can fall on the receiving carrier 33.

[0048] The transfer device of this embodiment can accurately position the product posture of the sheet metal part 4, and the suction cup 210 tightly sucks the sheet metal part 4 to prevent it from shifting or falling during the flipping process; the lifting component 32 in the transfer component 3 can reduce the height of the falling material and smoothly receive the material; after receiving the material, the driving component 31 in the material receiving carrier 33 component will move the material receiving carrier 33 out, providing precise positioning for the second set of tapping machine feeding grippers, thereby achieving accurate precision after flipping.

[0049] like Figure 1 As shown, in some embodiments, the number of the carrier plates in the rotating carrier assembly can be two, namely, a first carrier plate 21 and a second carrier plate 22. The second carrier plate 22 and the first carrier plate 21 are arranged 180 degrees apart about the axis of the rotating shaft 23. That is, when the first carrier plate 21 faces directly upward, the second carrier plate 22 faces directly downward; when the first carrier plate 21 faces directly downward, the second carrier plate 22 faces directly upward.

[0050] When the gripper places the sheet metal part 4 product after the first tapping on the positioning pin 211 on the first carrier 21, the vacuum generator generates negative pressure. After the suction cup 210 sucks the sheet metal part 4, the motor component 24 controls the rotation axis 23 to rotate, driving the product to flip 180 degrees, so that the first carrier 21 is opposite to the receiving carrier 33, and the second carrier 22 is facing upward. At this time, when the first carrier 21 releases the sheet metal part 4, another sheet metal part 4 can be placed on the second carrier 22. Then control the rotation axis 23 to continue to rotate 180 degrees in the same direction, so that the second carrier 22 is opposite to the receiving carrier 33, and the first carrier 21 is facing upward. Continue the above work. This cycle continues, which can increase the transfer rate of the sheet metal part 4.

[0051] Of course, in some other embodiments, the number of the carrier plates in the rotating carrier assembly can be three or four, etc., which can be determined according to factors such as the shape and size of the sheet metal part 4. When the number of the carrier plates is three, one carrier plate will be opposite to the receiving carrier 33 every time the rotating circle rotates 120 degrees. This embodiment is described only by taking the rotating carrier assembly including two carrier plates as an example.

[0052] Preferably, multiple sets of rotating carrier assemblies can be arranged on each rotating shaft 23 of this embodiment. The multiple sets of rotating carrier assemblies are arranged at intervals along the axial direction of the rotating shaft 23. Figure 1 shown.

[0053] A plurality of groups of flip cache components 2 may be arranged on the fixed frame 1, and the rotation axes 23 in the plurality of groups of flip cache components 2 are parallel to each other. Figure 1 shown.

[0054] like Figure 5 As shown, in some embodiments, the positioning pins 211 and the suction cup 210 on the carrying plate are both disposed on the first surface of the carrying plate.

[0055] A support 212 for sleeved on the rotating shaft 23 is provided on the second surface of the carrier plate.

[0056] As for the specific position of the vacuum generator on the carrier plate, this embodiment does not make any specific limitation, and preferably, it is arranged on the same surface as the support 212. The working principle and specific structure of the vacuum generator belong to the prior art and will not be described in detail.

[0057] like Figure 3 As shown, in some embodiments, the fixing frame 1 includes a rectangular frame and support columns 13 for supporting the rectangular frame.

[0058] The rectangular frame includes two opposite shaft support plates 10 and two opposite side plates 11. Each shaft support plate 10 corresponds to two support columns 13 respectively.

[0059] Two connecting plates 14 are respectively disposed on the outer sides of the two rotating shaft support plates 10. The top ends of the supporting columns 13 are connected to the connecting plates 14, and the bottom ends are connected to the base 15 for supporting on the ground.

[0060] Of course, in some other embodiments, a connecting plate 14 may also be provided on the outer sides of the two side plates 11 , and correspondingly, the top end of the supporting column 13 is connected to the connecting plate 14 on the side plate 11 .

[0061] Further, Figure 4 As shown, the two ends of the rotating shaft 23 are respectively connected to the seat bearings 25. The two rotating shaft support plates 10 of the fixed frame 1 are provided with bearing holes 16 for installing and fixing the seat bearings 25. Figure 3 As shown, this structure facilitates the installation of the flip component.

[0062] The motor component 24 of this embodiment can be fixed on the rotating shaft support plate 10. The motor shaft of the motor component 24 can be connected to the rotating shaft 23 through a coupling, so as to drive the rotating shaft 23 to rotate. The motor component 24 can be fixed on the rotating shaft support plate 10 through a motor frame.

[0063] When two groups of flip cache assemblies 2 can be set on the fixed frame 1, the rotating shafts 23 in the two groups of rotating carrier assemblies can be connected through chain transmission, and the motor component 24 can be connected to the rotating shaft 23 in one group of rotating carrier assemblies, and then the two rotating shafts 23 are controlled to rotate synchronously through chain transmission.

[0064] like Figure 7 As shown, in some embodiments, the receiving carrier 33 includes a receiving tray and a photoelectric switch 331 disposed on the receiving tray. The photoelectric switch 331 is used to detect whether there is a sheet metal part 4 on the receiving tray. The photoelectric switch 331 is the abbreviation of a photoelectric proximity switch, which uses the blocking or reflection of the light beam by the detected object to connect the circuit by the synchronous circuit, thereby detecting the presence or absence of the object.

[0065] Preferably, the receiving tray of this embodiment is provided with a shelf groove 330 for placing the sheet metal part 4. A switch bracket 332 is provided at the bottom of the shelf groove 330, and a photoelectric switch 331 is fixed on the switch bracket 332. When the carrying tray releases the sheet metal part 4, the sheet metal part 4 can fall into the shelf groove 330 on the receiving tray to ensure the stability of the sheet metal part 4 on the receiving tray.

[0066] It should be noted that the number of the shelf slots 330 on the receiving tray of this embodiment is the same as the number of the rotating carrier components in the flip buffer component 2. That is, each rotating carrier component corresponds to a shelf slot 330.

[0067] like Figure 8 and Fig. 9 As shown, in some embodiments, the lifting assembly 32 includes a bottom plate 328 , a lifting base plate 325 , a carrier connecting plate 320 , and a cylinder assembly.

[0068] The bottom plate 328 is connected to the driving component 31 , and the lifting base plate 325 is located above the bottom plate 328 .

[0069] The carrier connecting plate 320 is located above the lifting base plate 325 and is fixedly connected to the receiving carrier 33. The cylinder assembly is located between the lifting base plate 325 and the carrier connecting plate 320. The cylinder assembly includes a first cylinder 324 and a second cylinder 323 respectively fixed on the lifting base plate 325. The piston rods of the two cylinders are respectively extended and retracted in the vertical direction.

[0070] The first cylinder 324 is arranged downward, and the free end of its piston rod passes through the lifting base plate 325 and is connected to the bottom plate 328 through the floating joint 326. The second cylinder 323 is arranged upward, and the free end of its piston rod is connected to the carrier connecting plate 320. The lifting height of the receiving carrier 33 can be increased by controlling the extension and retraction of the piston rods of the two cylinders.

[0071] The stroke of the first cylinder 324 of this embodiment is different from the stroke of the second cylinder 323. The stroke of the first cylinder 324 can be a short stroke, and the stroke of the second cylinder 323 can be a long stroke. That is, the stroke of the first cylinder 324 is smaller than the stroke of the second cylinder 323.

[0072] When controlling the receiving carrier 33 to receive the sheet metal part 4, the piston rod of the second cylinder 323 can be controlled to extend first, so that the receiving carrier 33 quickly approaches the sheet metal part 4 adsorbed on the carrier plate of the rotating shaft 23. When the receiving plate is about 5 mm away from the sheet metal part 4, the piston rod of the first cylinder 324 is controlled to extend, thereby driving the lifting base plate 325 and the second cylinder 323 thereon to rise for the second time, and finally let the sheet metal part 4 fall into the shelf groove 330 of the receiving plate to stably receive the sheet metal part 4. Then the first cylinder 324 is controlled to reset, and the second cylinder 323 is reset to continue the next action.

[0073] In the lifting assembly of this embodiment, two cylinders with different strokes are arranged, so that the material receiving carrier 33 can be lifted step by step, thereby minimizing the height of the falling material and ensuring smooth material receiving.

[0074] Further, in some embodiments, a long shaft sleeve 321 and a short shaft sleeve 329 are provided on the lifting base plate 325. The long shaft sleeve 321 and the short shaft sleeve 329 are respectively arranged vertically on the lifting base plate 325, and the lifting base plate 325 is respectively provided with through holes communicating with the two sleeves.

[0075] The carrier connecting plate 320 is provided with a long optical axis 322 extending downward, and the bottom plate 328 is provided with a short optical axis 327 extending upward.

[0076] The long optical axis 322 is inserted into the long axis sleeve 321 and matches with the clearance, and the short optical axis 327 is inserted into the short axis sleeve 329 and matches with the clearance. In this way, the long optical axis 322 and the short optical axis 327 are matched with the sleeves respectively, which can guide the lifting of the lifting base plate 325 and the carrier connecting plate 320, thereby ensuring the stability of the lifting.

[0077] like Figure 6 As shown, in some embodiments, the driving component 31 includes a frame (not shown) and a rodless cylinder 310 disposed on the frame. The rodless cylinder 310 is fixed to the frame through a mounting bracket 311.

[0078] In some embodiments, the piston in the rodless cylinder 310 is connected to the bottom plate 328 in the lifting assembly 32, and the movement of the piston can drive the lifting assembly 32, the carrier connecting plate 320 and the sheet metal part 4 to move synchronously. As for the specific structure and working principle of the rodless cylinder 310, they belong to the prior art and are not described in detail. The driving component 31 can keep the sheet metal part 4 from shifting during the movement of the product.

[0079] In addition, the driving component 31 also includes a drag chain groove 313 arranged on the frame, and the drag chain 312 for connecting the rodless cylinder 310 can be arranged in the drag chain groove 313. When the piston on the rodless cylinder 310 moves, the corresponding drag chain 312 moves in the drag chain groove 313.

[0080] 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. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
