Abstract
Description
Technical Field
[0001] The utility model relates to the field of automated production, in particular to an automatic workpiece turning device. Background Art
[0002] When carrying out industrial automatic production, sometimes both the front and back sides of the workpiece need to be processed (such as drilling, screwing, etc.). The traditional practice is to use a conveyor belt to transport the workpiece to the flipping station after the front side processing is completed. The operator at the flipping station manually flips the workpiece so that the bottom side of the workpiece faces up, and places the workpiece with the bottom side facing up on the conveyor belt to be transported to the next processing station. This purely manual flipping operation requires human resources and has relatively low work efficiency. At the same time, after manual flipping, when the workpiece is placed on the conveyor belt again, the accuracy of the placement position needs to be strictly guaranteed. Once there is a deviation in the placement position, it may affect the subsequent processing accuracy.
[0003] Therefore, a method or device capable of solving the above problems is now needed. Summary of the invention

[0006] A stopper 5 and a position sensor 6 are provided at the end of the conveyor belt mechanism 2.

[0012] The automatic workpiece turning device of this structural form has a simple structure, ingenious design, and reasonable layout. It designs a special structure to solve the problems existing in the traditional manual operation method. It can use the first translation manipulator to transport the workpiece transported by the conveyor belt to the turning station and suspend it. Then, after the turning manipulator clamps the workpiece, the first translation manipulator releases the workpiece and moves it away.

[0018] The specific implementation of the present utility model will be described below in conjunction with the accompanying drawings. Figures 1 to 5 As shown: A workpiece automatic turning device comprises a workbench 1, on which a conveyor belt mechanism 2, a turning mechanism 3 and a material receiving table 4 are arranged.
[0019] A stopper 5 and a position sensor 6 are provided at the end of the conveyor belt mechanism 2.
[0020] The flipping mechanism 3 includes a support frame 7, an X-axis cylinder 8 is arranged at the top of the support frame 7, the working end of the X-axis cylinder 8 is connected to an X-axis slide 9 slidably connected to the support frame 7, a Z-axis cylinder 10 is arranged at the top of the X-axis slide 9, the working end of the Z-axis cylinder 10 is connected to a Z-axis slide 11 slidably connected to the X-axis slide 9, and two material-taking clamps 12 are symmetrically arranged on the Z-axis slide 11.
[0021] The flipping mechanism further comprises a Y-axis cylinder 13, the working end of which is connected to a Y-axis bracket, a rotating cylinder 14 is arranged on the Y-axis bracket, and the output end of the rotating cylinder 14 is connected to a flipping clamp 15.
[0022] The distance between the two material-retrieving jaws 12 is H, the central axis of the conveyor belt mechanism 2 is L1, the central axis of the flipping jaw 15 is L2, and the position sensor 6 corresponds to the material-retrieving position at the end of the conveyor belt mechanism 2.
[0023] The L1 and L2 intersect at point a, the distance between the center of the material receiving platform 4 and point a is H, the center point of the material taking position is point b, and the distance between point a and point b is also H.
[0024] The working process of the automatic workpiece turning device of the embodiment of the utility model is as follows: the workpiece 16 that needs to be turned over is transferred from the previous workstation to the entrance of the conveyor belt mechanism 2, and moves under the action of the conveyor belt mechanism 2. When the workpiece 16 moves to the material taking position, it is blocked by the stop block 5. At this time, the position sensor 6 detects that there is a workpiece waiting for turning over at the material taking position of the conveyor belt mechanism 2;
[0025] Of the two material-picking jaws 12, the one close to the conveyor belt mechanism 2 is the first material-picking jaw, and the other is the second material-picking jaw. In the initial state, the first material-picking jaw is located above the material-picking position, and the second material-picking jaw is located above point a. After the control system sends a signal, the Z-axis cylinder 10 drives the Z-axis slide 11 downward, the first material-picking jaw moves downward and clamps the workpiece 16, and then the Z-axis slide 11 moves upward, the workpiece 16 is taken away from the material-picking position, and the next workpiece 16 will move to the material-picking position under the action of the conveyor belt mechanism 2 and wait for the next flipping operation;
[0026] The X-axis cylinder 8 is retracted, driving the X-axis slide 9 to move a unit distance H in the direction away from the conveyor mechanism 2. At this time, the second material-retrieving clamping jaw is located above the center point of the receiving platform 4, and the first material-retrieving clamping jaw holding the workpiece 16 is located above point a;
[0027] The Z-axis slide plate 11 moves downward, and the two material-taking clamping claws 12 move downward, so that the center point of the workpiece 16 coincides with point a, and the workpiece 16 is now in the flipping position;
[0028] The flipping jaw 15 moves to clamp the workpiece 16 hovering at point a. Since the two clamping parts of the flipping jaw 15 are distributed longitudinally, and the two clamping parts of the material picking jaw 12 are distributed horizontally, the flipping jaw 15 will not interfere with the material picking jaw 12 during the action (the material picking jaw 12 clamps the two side surfaces of the workpiece 16, and the flipping jaw 15 clamps the upper and lower end surfaces of the workpiece 16). After the flipping jaw 15 clamps the workpiece 16, the first material picking jaw is released and rises, and the flipping jaw 15 drives the workpiece 16 to flip up and down 180°, so that its bottom surface faces upward, completing the flipping action;
[0029] While the workpiece 16 moves, the X-axis slide 9 moves in the opposite direction by a distance H. At this time, the first material picking jaw returns to the top of the material picking position, and the second material picking jaw moves to the top of point a; the Z-axis slide 11 drives the two material picking jaws 12 downward, the first material picking jaw clamps the second workpiece 16, and the second material picking jaw clamps the first workpiece 16 suspended at point a by the flipping jaw 15. After the action of the material picking jaw 12 is completed, the flipping jaw 15 is released and retreated, and then the Z-axis slide 11 rises, and the Z-axis slide 9 moves a unit distance H toward the direction of the receiving table 4 again. At this time, the first workpiece 16 is located above the receiving table 4, and the second workpiece 16 is located above point a.
[0030] The Z-axis slide 11 moves downward, and the first workpiece 16 with the bottom facing upward is placed on the receiving table 4, while the second workpiece 16 still facing upward moves to point a, and the flipping clamp 15 repeats the above action to flip the second workpiece 16;
[0031] The second material picking jaw returns to above point a, and the first material picking jaw returns to above the material picking position, waiting for the next operation. During the above process, the first workpiece 16 placed on the receiving table 4 with the bottom facing up is taken away by the robot and transported to the subsequent workstation. The receiving table 4 is empty, waiting for the second workpiece 16.
[0032] If the above process is repeated, the operation of turning over multiple workpieces 16 in sequence can be achieved.
