[0029] like Figures 1 to 3As shown, an automatic feeding and workstation switching system comprises a support seat 1 and a turnover storage tray 2 mounted on the support seat 1, the turnover storage tray 2 having a plurality of plug-in rods 3 for placing workpieces distributed in a circumferential array direction; it also comprises a mounting table 4, a lifting plate 5 is slidably arranged on the mounting table 4 along the plumb direction, a lifting drive mechanism is fixedly arranged between the lifting plate 5 and the mounting table 4, a turntable 6 is rotatably arranged on the lifting plate 5, a docking mechanism is fixedly arranged between the turntable 6 and the turnover storage tray 2, and a workstation switching mechanism is also fixedly arranged between the turntable 6 and the lifting plate 5; two symmetrically arranged positioning plug plates 7 are also movably arranged on the mounting table 4, and the positioning plug plates 7 have a connection with the plug-in rods 3, arc-shaped surfaces 9 for guiding the plug-in rod 3 are symmetrically arranged on both sides of the docking groove 8, and a moving mechanism for driving the positioning plug-in plate 7 to move is arranged between the positioning plug-in plate 7 and the mounting platform 4; it also includes two fine-tuning mechanisms, and the two fine-tuning mechanisms are symmetrically arranged on both sides of the turntable 6, each of the fine-tuning mechanisms includes a driving plate and a driving mechanism for driving the driving plate to slide, and the driving plate has a driving surface; it also includes a controller and a first detection element, the first detection element sends the position of the plug-in rod 3 and the corresponding docking groove 8 to the controller, and the controller controls the fine-tuning mechanism based on the detection value of the first detection element so that the plug-in rod 3 is inserted into the corresponding docking groove 8.

[0030] Specifically, the steps of the system include: transporting the turnover storage tray 2 with cylindrical workpieces placed on each connecting rod 3 to the support seat 1 through an external conveyor belt or a transfer device such as a robotic arm; a mechanism for painting the surface of the workpiece is also provided above the support seat 1; each connecting rod 3 needs to be adjusted to a position matching the working station of the painting mechanism in turn; however, when being transported to the support seat 1 through a conveyor belt or other transfer device, the position of each connecting rod 3 is prone to deviation; at this time, the position of each connecting rod 3 is detected by a first detection element and compared with the position of the docking slot 8 to determine whether it is away from the connecting rod 3 or not. The plug-in rod 3 closest to the docking slot 8 is offset to the left or to the right. If it is offset to the left, the fine-tuning mechanism on the left is controlled by the controller to press the turnover storage tray 2 to move toward the positioning plug plate 7. During this movement, the turnover storage tray 2 not only slides, but also produces a certain angle deflection, so that the plug-in rod 3 on the left moves to the position of the positioning slot on the left. When the plug-in rod 3 contacts the arc surface 9, it slides along the arc surface 9 into the positioning slot to complete the positioning of the left positioning slot, and then the fine-tuning mechanism on the right is controlled by the controller to dock and position the plug-in rod 3 on the right with the positioning slot. After the positioning grooves on both sides are positioned with a plug-in rod 3, one of the plug-in rods 3 on the turnover storage tray 2 is at the painting station, and the docking mechanism can be docked. After the docking is completed, the controller controls the moving mechanism to move the positioning plug plate 7 to a position that does not interfere with the rotation of the turnover storage tray 2. When the workpiece on the plug-in rod 3 of this station has completed the painting work, the turnover storage tray 2 needs to be rotated so that the plug-in rod 3 at the next position can reach this station. At this time, the turntable 6 and the turnover storage tray 2 are connected as a whole under the action of the docking mechanism. At this time, the turntable 6 can be driven to rotate by the station switching mechanism to drive the turnover storage tray 2 to rotate, and then the above operation is repeated until all workpieces are processed. In this embodiment, the controller controls the fine-tuning mechanism according to the detection result of the first detection element to position the turnover storage tray 2 with the positioning plug plate 7, thereby achieving the purpose of transporting the connecting rods 3 and the workpieces on the turnover storage tray 2 to the processing station, and then switches the connecting rods 3 in turn through the station switching mechanism until the workpieces on all the connecting rods 3 are processed, thereby realizing batch loading and brushing processing of such cylindrical workpieces, greatly improving production efficiency and increasing the factory's production capacity.

[0031] The driving plate has a driving surface for driving the turnover storage tray 2, and the angle between the direction of the force applied by the driving surface on the turnover storage tray 2 and the sliding direction of the turnover storage tray 2 on the support seat 1 toward the positioning plug plate 7 is an acute angle. Specifically, the movement direction of the driving plate on the turnover storage tray 2 can have multiple directions, as long as the pressure applied by the driving surface on the side wall of the turnover storage tray 2 can drive the turnover storage tray 2 to move toward the side of the positioning plug plate 7.

[0032] The driving plate is a triangular plate 12, the sliding direction of the driving plate on the support seat 1 is parallel to the sliding direction of the turnover storage tray 2 on the support seat 1 toward the positioning plug plate 7, and the hypotenuse of the triangular plate 12 abuts against the side wall of the turnover storage tray 2; the driving mechanism includes a first cylinder 10 fixedly arranged on the support seat 1, and the telescopic end of the first cylinder 10 is installed with a motor 23 through a mounting plate 11, and the output shaft of the motor 23 is fixedly connected to the driving plate. Specifically, when the triangular plate 12 is driven by the cylinder to slide, the pressure applied by its inclined surface to the turnover storage tray 2 can be decomposed into a force parallel to the sliding direction of the turnover storage tray 2 on the support seat 1 toward the positioning plug plate 7, and then the turnover storage tray 2 can be driven to move relative to the positioning plug plate 7. In order to avoid the triangular plate 12 from blocking the turnover storage tray 2 when loading, the turnover storage tray 2 can be rotated to a position where it does not block the loading of the turnover storage tray 2 by the motor 23.

[0033] The moving mechanism includes a slide rail 13 and a slider 14 that cooperate with each other. The slide rail 13 is fixedly arranged on the mounting platform 4, and the slider 14 is fixedly connected to the positioning plug plate 7. Specifically, when positioning the turnover storage tray 2, the slider 14 is adjusted to the corresponding position on the slide rail 13 so that the docking groove 8 can correspond to the plug rod 3. When switching the workstation of the turnover storage tray 2, the slider 14 is moved to a position on the slide rail 13 that does not affect the rotation of the turnover storage tray 2, such as the top of the slide rail 13. At this time, the turnover storage tray 2 can rotate freely without interference. Here, the power for the sliding of the slider 14 on the slide rail 13 can be driven by the external motor 23 screw, or it can be driven by an external cylinder. Any power mechanism that can drive the slider 14 to move can be used here.

[0034] A sleeve 15 is fixedly provided at the bottom of the turntable 6, and a central shaft 16 that is rotatably matched with the sleeve 15 is fixedly provided on the lifting plate 5. Specifically, the rotation of the turntable 6 is achieved by the rotation of the sleeve 15 on the central shaft 16, and a bearing may be further provided between the sleeve 15 and the central shaft 16.

[0035] The docking mechanism includes a plurality of mutually cooperating latches 17 and insertion holes 18, wherein the latches 17 are fixedly arranged on the turntable 6 in a circumferential array, and the insertion holes 18 are arranged in a circumferential array on the turnover storage tray 2. Specifically, when the latches 17 are inserted into the insertion holes 18, the turntable 6 and the turnover storage tray 2 can be docked.

[0036] The workstation switching mechanism includes a second cylinder 19 and a positioning seat 20. The positioning seat 20 is fixedly arranged on the lifting plate 5. The second cylinder 19 is rotatably connected to the positioning seat 20. The telescopic end of the second cylinder 19 is fixedly connected to the turntable 6 via a connecting shaft. Specifically, since the distribution of the connecting rods 3 on the turnover storage tray 2 is in a circular array, the central angles between two adjacent connecting rods 3 are equal. During operation, when it is necessary to switch the work station, the pin 17 is connected to the socket 18, and then the turntable 6 is driven to rotate by extending the output end of the second cylinder 19 to drive the turnover storage tray 2 to rotate. After the switching is completed, the turntable 6 and the turnover storage tray 2 are separated by the lifting drive mechanism, that is, the pin 17 is pulled out of the socket 18. At this time, the turnover storage tray 2 falls back on the support frame, and the turntable 6 is reset by the second cylinder 19, ready to connect with the turnover storage tray 2 of the next work station. In this process, as long as the extension of the second cylinder 19 is controlled to a fixed value, the socket 18 can be matched with the connecting pin 17 every time the switch is made.

[0037] The lifting drive mechanism includes a hydraulic cylinder 21, which is fixedly mounted on the mounting platform 4, and the output end of the hydraulic cylinder 21 is fixedly connected to the lifting plate 5. Specifically, the entire lifting platform and the device on the lifting platform are driven up and down by the hydraulic cylinder 21 to complete the docking of the socket 18 and the latch 17.

[0038] A plurality of guide posts 22 are also slidably arranged between the lifting plate 5 and the mounting platform 4. Specifically, the guide posts 22 make the lifting plate 5 smoother when it is lifted and lowered, thereby ensuring the accuracy of the docking between the jack 18 and the latch 17.

[0039] The first detection element includes a sonic positioning device, which is fixedly arranged on the positioning plug plate 7. Specifically, the sonic positioning device can quickly locate the position of the plug rod 3 by reflecting the sound waves. In addition, the position of the plug rod 3 can also be determined by visual detection equipment and other devices. Any device that can determine the position of the plug rod 3 can be used here.

[0040] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
