[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] like Figure 1 As shown, a workpiece angle positioning device includes a clamping component 1, a vertical sliding component 2, a support component 3, a positioning component 4, and a tray 5. The clamping component 1 is fixedly connected to the vertical sliding component 2, which is located at the upper end of the support component 3. The positioning component 4 and the support component 3 are parallel to each other and opposite to each other. The tray 5 is located below the clamping component 4 and between the positioning component 2 and the support component 5. The clamping component 1 is used to grip the workpiece 13, and the vertical sliding component 2 is used to move the clamping component 1 and the workpiece 13 closer to or away from the support component 5.

[0033] like Figure 2As shown, the clamping assembly 1 includes a support frame 15, which includes a first metal plate 151, a second metal plate 152, and a third metal plate 153. One side of the second metal plate 152 is fixedly installed to the vertical sliding assembly 2, and the other side of the second metal plate 152 is provided with the first metal plate 151 and the third metal plate 153 respectively. The first metal plate 151 and the third metal plate 153 are arranged parallel to each other. The first metal plate 151 is provided with a first circular hole 1511, and the third metal plate 153 is provided with a second circular hole 1531. The first circular hole 1511 and the second circular hole 1531 are coaxially arranged.

[0034] like Figure 3 As shown, the support frame 15 also includes two triangular metal plates 154, and a triangular metal plate 154 is installed at each end of the second metal plate 152. One end of each triangular metal plate 154 is fixedly connected to the upper end of the first metal plate 151, and the third metal plate 153 is located between the two triangular metal plates 154.

[0035] like Figure 3 As shown, the clamping assembly 1 also includes a servo motor 11 and a pneumatic chuck 12. The servo motor 11 is mounted on the third metal plate 153. The output shaft of the servo motor 11 passes through the first circular hole 1511 and the second circular hole 1531 and is connected to the pneumatic chuck 12. The pneumatic chuck 12 is mounted on the lower end of the first metal plate 151, and the workpiece 13 is clamped below the pneumatic chuck 12. When the workpiece 13 moves directly below the clamping assembly 1, the controller controls the pneumatic chuck 12 to clamp the workpiece 13. The pneumatic chuck 12 is existing technology, and its model is GAL-15. The servo motor 11 is also existing technology, and its model is MS1H4. After the workpiece 13 is clamped, the servo motor 11 will rotate, which can rotate the workpiece 14 to a suitable angle, thereby replacing manual angle adjustment. This allows for precise control of the workpiece 12 angle, reducing manpower waste and improving work efficiency.

[0036] like Figure 4As shown, the vertical sliding assembly 2 includes a motor 21, a slide rail 22, a slider 23, and a mounting base 25. The mounting base 25 is fixedly mounted on the support assembly 3. A lead screw is rotatably connected to the mounting base 25, and one end of the lead screw is fixedly connected to the output end of the motor 21. The motor 21 is fixedly mounted to the mounting base 25. The outer periphery of the lead screw is threadedly connected to the slider 23. The lower end of the slider 23 is slidably connected to the periphery of the slide rail 22. The slide rail 22 is fixedly mounted on the mounting base 25, and the slide rail 22 and the lead screw are arranged parallel to each other. A support frame 15 is mounted on one side of the slider 23. A positioning plate 26 and two limiters 24 are provided on one side of the mounting base 25. The two limiters 24 are arranged parallel to each other, and each limiter 24 is mounted on the mounting base 25. One end of the positioning plate 26 is mounted on the slider 23, and the other end of the positioning plate 26 can sense the actuation end of either limiter 24. The motor 21 is prior art, and the model of the motor 21 is MS1H4.

[0037] When workpiece 13 moves to the lower end of clamping assembly 1, the controller sends a signal to motor 21. The output end of motor 21 rotates, driving the lead screw to rotate. Since the lead screw is connected to slider 23, and the outer periphery of slider 23 is slidably connected to slide rail 22, slider 23 moves downward, driving support frame 15 and clamping assembly 1 fixedly connected above it to move downward. The controller controls pneumatic chuck 12 to clamp workpiece 13. Then motor 21 reverses, causing lead screw to also reverse, causing slider 23 to move upward, driving support frame 15 and clamping assembly 1 fixedly connected above it to move upward as well, lifting workpiece 13 from tray 5. The controller controls servo motor 11 to rotate to adjust the angle of workpiece 13. After the angle adjustment is completed, motor 21 repeats the above actions to place workpiece 14 on tray 5, and then retracts and resets. Vertical sliding assembly 2 allows clamping assembly 1 to slide vertically and cooperate to complete the clamping and placement actions. Compared with manual workpiece angle reset, it can save manpower, improve work efficiency, and is more continuous and faster.

[0038] like Figure 4 As shown, limiter 24 is a photoelectric sensor, which is existing technology, and the model number of the photoelectric sensor is FZDK10P5101. The positioning piece 26 on slider 23 moves with slider 23. When a positioning piece 26 passes through one of the limiters 24, the positioning piece 26 will block the light source. At this time, the limiter 24 will send a signal to the controller, indicating that slider 23 has moved to the position. The controller will then send a signal to motor 21, causing motor 21 to stop until the controller reverses motor 21 again. Repeating the above movement can make the clamping component 1 on slider 23 reciprocate. Compared with mechanical limiters, photoelectric sensors can avoid mechanical friction and scratches, reduce mechanical losses and energy consumption, extend the service life of the device and improve safety.

[0039] like Figure 5As shown, the positioning component 4 includes a bracket 41 and a support plate 43, which are arranged perpendicularly to each other. The support plate 43 is slidably connected to the periphery of the bracket 41. A laser displacement sensor 45 is installed at one end of the support plate 43. The support plate 43 is fixed to the relative position of the bracket 41 by a pin 44. The workpiece 13 has a notch 14, and the laser displacement sensor 45 is used to sense the presence of the notch 14. A scale 42 is installed on the support plate 43, which is used to read the specific data of the relative height of the support plate 43. The laser displacement sensor 45 is prior art, and the model of the laser displacement sensor 47 is HG-C1030.

[0040] The position of the support plate 43 can be adjusted according to the size of the workpiece 13 and fixed with pins 44. A scale 42 reads the specific value of the relative height of the support plate 43. The laser displacement sensor 45 sends an infrared signal towards the workpiece 13 to measure the distance between the laser displacement sensor 45 and the workpiece 13. When the workpiece 13 rotates until the notch 14 on the workpiece 13 aligns with the laser displacement sensor 47, the reading of the laser displacement sensor 47 changes, thus determining that the workpiece 14 has rotated to the appropriate position and sending a signal to the controller to stop the rotation of the servo motor 11. The positioning component 4 can achieve accurate positioning, reduce energy loss, and improve efficiency. Compared with traditional mechanical positioning, it avoids wear and collisions to the workpiece. Furthermore, the scale 42 can record the data of the required laser displacement sensor height for workpieces of different specifications, so that subsequent batches of workpieces with the same specifications and dimensions can be used.

[0041] like Figure 6 As shown, the tray 5 includes a base 51 and a circular seat 52. The circular seat 52 is fixedly connected to the base 51. The base 51 is set in a fixed position or on the transmission line. The lower end of the workpiece 13 can be inserted into the inner ring of the upper end of the circular seat 52.

[0042] The working process of a workpiece angle positioning device:

[0043] The position of the support plate 43 is adjusted according to the size of the workpiece 13 and fixed with pins 44. When the workpiece 13 moves to the lower end of the clamping assembly 1, the controller sends a signal to the motor 21. The output end of the motor 21 rotates, which drives the lead screw to rotate. Since the lead screw is connected to the slider 23 and the outer periphery of the slider 23 is slidably connected to the slide rail 22, the slider 23 moves downward and drives the support frame 15 and the clamping assembly 1 fixedly connected above it to move downward. The controller controls the pneumatic chuck 12 to clamp the workpiece 13. Afterward, the motor 21 will reverse, causing the lead screw to rotate in the opposite direction, causing the slider 23 to move upward and drive the support frame 15 and the clamping assembly 1 fixedly connected above it to move downward. The motor 21 moves upwards to pick up workpiece 13 from tray 5. The controller controls the servo motor 11 to rotate to adjust the angle of workpiece 13. The laser displacement sensor 45 sends an infrared signal toward workpiece 13 to measure the distance between the laser displacement sensor 45 and workpiece 13. When workpiece 13 rotates until the notch 14 on workpiece 13 is aligned with the laser displacement sensor 47, the reading of the laser displacement sensor 47 changes to determine that workpiece 14 has rotated to the appropriate position and sends a signal to the controller to stop the rotation of the servo motor 11. After the angle adjustment is completed, the motor 21 repeats the above action to put workpiece 14 back onto tray 5 and then retracts and resets.

[0044] The control method in this embodiment is controlled by a controller. The controller circuit can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this document is mainly used to protect mechanical devices, and the control method and circuit connection will not be explained in detail here.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
