Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0034] See also Figures 1 to 7 The transplanting and rotating device provided in the embodiment of the present application is now described. The transplanting and rotating device provided in the embodiment of the present application includes a translation mechanism 11 and a rotation mechanism 22.

[0035] The translation mechanism 1 includes a moving member 11 and a transplanting platform 12 . The moving member 11 is connected to the transplanting platform 12 to drive the transplanting platform 12 to move.

[0036] The rotating mechanism 2 includes a screw 21, a rotating member 22, a synchronous rotating assembly 23 and a rotating seat 24. The rotating seat 24 is used to carry the workpiece. The rotating seat 24 is rotatably installed on the transplanting platform 12. The rotating member 22 is movably sleeved on the screw 21, and a spiral transmission structure is provided between the rotating member 22 and the screw 21. The synchronous rotating assembly 23 is respectively connected to the rotating seat 24 and the rotating member 22, and is used to make the rotating seat 24 and the rotating member 22 move synchronously.

[0037] The workpiece in the embodiment of the present application may be a U-shaped aluminum tray to be laser processed. In addition, it may also be other workpieces to be processed that require angle change.

[0038] The moving member 11 may be a linear motor, an electric cylinder or a pneumatic cylinder, preferably a rodless pneumatic cylinder. The moving direction of the moving member 11 is parallel to the length direction of the lead screw 21 .

[0039] The screw rod 21 and the rotating member 22 of the rotating mechanism 2 can be connected by threads, and the synchronous rotation component 23 can include a driving gear and a driven gear. The driving gear is sleeved on the screw rod 21 and connected to the rotating member 22, and the driven gear is connected to the rotating seat 24. The driving gear and the driven gear are engaged. When the rotating member 22 slides along the length direction of the screw rod 21 and spirally rotates around the outer wall of the screw rod 21, the rotating seat 24 is driven by the driving gear and the driven gear to rotate on the transplanting platform 12 along the rotating axis parallel to the length direction of the screw rod 21.

[0040] After the workpiece is placed in the rotating seat 24 of the rotating mechanism 2, the transferring platform 12 is driven to move along the length direction of the screw rod 21 by the moving part 11, which drives the synchronous rotating component 23, the rotating part 22, and the rotating seat 24 on the rotating mechanism 2 to move along the length direction of the screw rod 21. The rotating part 22 rotates spirally around the outer wall of the screw rod 21 while moving along the length direction of the screw rod 21. When the rotating part 22 rotates spirally around the outer wall of the screw rod 21, the rotating part 22 drives the rotating seat 24 to rotate on the transferring platform 12 along the rotating axis parallel to the length direction of the screw rod 21 through the synchronous rotating component 23. In this way, the workpiece on the rotating seat 24 is rotated while being transferred, so that the workpiece completes the posture conversion when it reaches the laser processing position, making the workpiece convenient for laser processing and improving production efficiency.

[0041] The transplanting and rotating device of the embodiment of the present application can achieve the transplanting and rotation of the workpiece only through a driving source of the moving part 11. Compared with a device that achieves translation through a motor and rotation through a cylinder, the transplanting and rotating device of the embodiment of the present application has lower cost.

[0042] See also Figure 3 、 Figure 4 、 Figure 5A spiral groove 211 is provided on the screw rod 21, and an insertion rod 221 is inserted on the side wall of the rotating member 22. One end of the insertion rod 221 is clamped in the spiral groove 211 of the screw rod 21 so that the rotating member 22 can rotate along the circumference of the screw rod 21 when it moves along the length direction of the screw rod 21.

[0043] The rotating member 22 moves from one end of the spiral groove 211 to the other end of the spiral groove 211, and the rotating member 22 rotates one full revolution along the outer wall of the screw rod 21. By controlling the movement distance of the rotating member 22 on the screw rod 21, the rotation angle of the rotating member 22 can be controlled, and the rotation angle of the workpiece on the rotating base 24 can be controlled by the synchronous rotation assembly 23.

[0044] See also Figure 3 、 Figure 4 The rotating mechanism 2 also includes a mounting seat 26, an adjusting mounting block 27 and a fixing screw. The screw rod 21 is passed through the mounting seat 26 and connected to the adjusting mounting block 27. The adjusting mounting block 27 is provided with a long arc-shaped adjusting hole 271 for adjusting the angle of the adjusting mounting block 27. The mounting seat 26 is provided with a fixing hole 261. The fixing screw is passed through the adjusting hole 271 and is threadedly connected to the fixing hole 261. By rotating the adjusting mounting block 27, the screw rod 21 can be rotated to adjust the angle of the spiral groove 211 on the screw rod 21.

[0045] Adjustment hole 271 is a long, curved, waist-shaped hole. The fixing threaded member can be a screw or a threaded rod, preferably a threaded rod. Loosening the threaded rod allows the adjustment mounting block 27 and the screw rod 21 to be rotated to adjust the angle of the spiral groove 211 on the screw rod 21. This allows the workpiece on the rotating seat 24 to rotate at the desired angle after the rotating member 22 moves on the screw rod 21. Tightening the threaded rod causes the head of the threaded rod to abut against the edge of the adjustment hole 271 on the adjustment mounting block 27, thereby fixing the angle of the adjustment mounting block 27 and simultaneously securing the screw rod 21.

[0046] Preferably, the synchronous rotation component 23 includes a driving wheel 231, a driven wheel 232 and a synchronous belt 233. The driving wheel 231 is sleeved on the screw rod 21, the driving wheel 231 is connected to the rotating member 22, the driven wheel 232 is connected to the rotating seat 24, and the synchronous belt 233 is sleeved on the driving wheel 231 and the driven wheel 232.

[0047] When the rotating member 22 spirally rotates around the outer wall of the screw rod 21, it can drive the driving wheel 231 to spirally rotate around the outer wall of the screw rod 21. The driving wheel 231 rotates, and the driven wheel 232 can be driven to rotate synchronously through the synchronous belt 233. The rotation of the driven wheel 232 drives the rotating seat 24 to rotate on the transplanting platform 12 along the rotating axis parallel to the length direction of the screw rod 21.

[0048] The driving wheel 231 or the driven wheel 232 is provided with teeth, and the synchronous belt 233 is provided with a toothed belt meshing with the teeth.

[0049] The toothed belt on the synchronous belt 233 meshes with the teeth on the driving wheel 231 or the driven wheel 232 to prevent the synchronous belt 233 from becoming loose due to aging and being unable to rotate with the rotation of the driving wheel 231 or the driven wheel 232 .

[0050] The rotating mechanism 2 further includes a fixing assembly 25 . The fixing assembly 25 is disposed on the rotating base 24 and is used to fix the workpiece.

[0051] A limiting groove for accommodating the workpiece is provided on the rotating seat 24. The fixing device may include a cylinder and a baffle. The cylinder is installed at the edge of the limiting groove. The cylinder is connected to the baffle by transmission. When the workpiece is placed in the limiting groove, the cylinder moves the baffle toward the limiting groove to cover the workpiece in the limiting groove, preventing the workpiece from falling out of the limiting groove when the rotating seat 24 rotates.

[0052] Preferably, see Figure 6 、 Figure 7 The fixed component includes a translation drive and a pressing unit. The pressing unit is used to abut the workpiece against the rotating seat. The translation drive is installed on the rotating seat. The translation drive drives the pressing unit to move toward or away from the workpiece.

[0053] The pressing unit can make the workpiece close to the rotating seat, preventing the workpiece from shaking during rotation and reducing the breakage rate of the workpiece.

[0054] The pressing unit may include a pressing block and a lifting drive component. The lifting drive component is connected to the translation drive component. The lifting drive component is connected to the pressing block for transmission to drive the pressing block to move in a direction perpendicular to the side of the rotating seat that supports the workpiece. The pressing block abuts against the workpiece, so that the workpiece can be tightly attached to the rotating seat to prevent the workpiece from shaking when rotating.

[0055] The translation drive 251 and the lifting drive can be electric cylinders, air cylinders or hydraulic cylinders, preferably air cylinders. The translation drive 251 is installed at the bottom of the rotating base 24 and drives the pressing unit to move in a direction parallel to the side of the rotating base that supports the workpiece.

[0056] Preferably, see Figure 6 、 Figure 7 The pressing unit includes a connecting block 252, an abutment member 253 and an elastic member 254. The abutment member 253 is used to abut against the workpiece. The abutment member 253 is installed on the connecting block 252. The two ends of the elastic member 254 abut against the abutment member 253 and the connecting block 252 respectively. The translation drive member 251 is transmission-connected with the connecting block 252 to drive the abutment member 253 to move toward or away from the workpiece.

[0057] A connecting block 252 is mounted on one side of the rotating base 24. It is provided with a connecting transverse portion extending above the upper limit slot of the rotating base 24. An abutting member 253 comprises a connecting rod and an abutting portion. The connecting rod is inserted into the connecting transverse portion. The abutting portion is mounted on the side of the connecting rod that is closest to the workpiece in the limit slot. The abutting portion is used to abut the workpiece. The length of the connecting rod is perpendicular to the bottom of the limit slot of the rotating base 24. An elastic member 254 is mounted between the abutting portion of the abutting member 253 and the connecting transverse portion of the connecting block 252.

[0058] The elastic member 254 can be a spring or elastic silicone rubber sleeved on the insertion rod 221, preferably a spring. One end of the spring abuts the connecting transverse portion of the connecting block 252, and the other end abuts the abutting portion of the abutting member 253. The translational drive member 251 moves the connecting block 252, the abutting member 253, and the elastic member 254 toward the workpiece, causing the abutting portion of the abutting member 253 to abut the workpiece, thereby clamping the workpiece between the abutting portion of the abutting member 253 and the retaining groove of the rotating seat 24. The elastic member 254 presses the abutting portion of the abutting member 253 against the workpiece, preventing it from falling out of the retaining groove when the rotating seat 24 rotates.

[0059] The end of the abutment member 253 that is closest to the workpiece is configured as an arcuate surface. The end of the abutment member 253 that is closest to the workpiece is configured as an abutment portion. The end surface of the abutment portion that is closest to the workpiece is configured as an arcuate surface, or the abutment portion is configured as a sphere. This can reduce friction when the abutment member 253 moves on the workpiece, preventing the abutment portion on the abutment member 253 from abrading the workpiece.

[0060] See also Figure 2 、 Figure 6 and Figure 7 A through hole 121 is provided on the transplanting platform 12, and a first supporting member 122 and a second supporting member 123 are mounted on both sides of the through hole 121 of the transplanting platform 12. The first supporting member 122 and the second supporting member 123 do not rotate with the rotation of the rotating base 24. A first rotating shaft 241 is provided on the side of the rotating base 24 close to the synchronous rotation component 23, and the fixing component 25 is installed on the side of the rotating base 24 away from the synchronous rotation component 23. A second rotating shaft 242 is provided on the connecting block 252 of the fixing component 25. The first rotating shaft 241 on the rotating base 24 is rotatably mounted on the first supporting member 122, and the second rotating shaft 242 is rotatably mounted on the second supporting member 123. The driving wheel 231 of the synchronous rotation component 23 is connected to the first rotating shaft 241 on the rotating base 24, so that the rotating base 24 is rotatably set on the transplanting platform 12.

[0061] See also Figure 1 、 Figure 2 The translation mechanism 1 further includes a base plate 13 , on which the moving member 11 is mounted. A limiting buffer member 131 is provided on the base plate 13 to prevent the transplanting platform 12 from overshooting.

[0062] A limiter and buffer 131 is positioned along the path of the transplanting platform 12. It comprises a limiter and a buffer. The limiter is mounted on the base plate 13, and the buffer is mounted on the side of the limiter near the transplanting platform 12. The buffer can be a spring or a silicone block. The limiter prevents the transplanting platform 12 from overshooting the processing station, while the buffer prevents the transplanting platform 12 from overshooting and potentially damaging it.

[0063] Guide rails and sliders can also be set on the base plate 13. The length direction of the guide rails is parallel to the length direction of the screw rod 21. The sliders are slidably connected to the guide rails, and the sliders are connected to the transplanting platform 12. The guide rails and sliders can provide support for the transplanting platform 12 and guide the transplanting platform 12 at the same time.
