Description

Technical Field

[0001] The invention relates to the field of machinery, in particular to an automatic conveying device. Background Art

[0002] In the field of modern manufacturing and logistics, the conveyor line system plays a vital role, and its performance directly affects key indicators such as production efficiency, cost control and product quality. With the continuous improvement of industrial automation, higher and higher requirements are put forward for the flexibility, accuracy and energy efficiency of conveyor lines in the process of handling and transporting workpieces.

[0003] Traditional conveyor lines usually use a design with multiple independent drive components to achieve the position change of workpieces, especially when the workpieces are moved horizontally first and then lifted. For example, a common method is to use a horizontal cylinder to control the horizontal movement of the workpiece, and then equip it with a vertical cylinder to achieve lifting operations. The use of multiple drive components not only increases the hardware cost of the equipment, including procurement cost, installation cost, and later maintenance cost. Each drive component requires a separate control system and supporting equipment, which makes the structure of the entire conveyor system complicated, increases the failure points, reduces the reliability and stability of the system, and further increases the cost of repair and maintenance.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0019] The lifting mechanism includes a connecting rod 13, and the four connecting rods 13 are divided into two groups and arranged on both sides of the slider 9. One end of the connecting rod 13 is connected to the slider 9 through a fixing bolt 24, and the other end is connected to the lifting plate 14 through a fixing bolt 24. A workpiece positioning plate 15 is installed on the lifting plate 14, and a cam follower 19 is fixed to the front end of the lifting plate 14. The workpiece 8 is placed on the workpiece positioning plate 15.

[0020] A spring support 17 is fixed to the connecting rod 13 and the sliding block 9 , respectively. The two spring supports 17 are connected via a spring 18 .

[0021] The connection structure between the connecting rod 13 and the slider 9 and the connecting rod 13 and the lifting plate 14: bearings 23 are provided at the upper and lower ends of the connecting rod, a spacer 25 is provided between the connecting rod 13 and the slider 9, and a spacer 25 is also provided between the connecting rod 13 and the lifting plate 14. The fixing bolt 24 connects the connecting rod 13, the spacer 25 and the slider 9 together, and the fixing bolt 24 also connects the connecting rod 13, the spacer 25 and the lifting plate 14 together.

[0022] The slide block 9 is also provided with a lifting plate limiting block 16 .

[0023] The connecting rod 13, the slider 9 and the lifting plate 14 form a parallelogram mechanism.

[0024] The working principle of the present invention is:

[0025] Initial preparation stage

[0026] The slider 9 is located on the right side of the slide 7. The slider 9, the lifting plate 14 and four connecting rods form a parallelogram mechanism. The pulling force of the spring 18 causes the lifting plate 14 to fall on the lifting plate limit block 16. At this time, the workpiece can be placed on the workpiece positioning plate 15, and the workpiece is in the initial position to be transported.

[0027] Horizontal movement stage

[0028] The servo motor 6 is started, and the servo motor 6 drives the slide 7, which in turn drives the slider 9 and the entire mechanism (including the lifting mechanism and the workpiece, etc.) installed on the slider 9 to move to the left as a whole. In this process, the entire mechanism maintains a relatively stable structural form, and the workpiece moves horizontally to the left along with the mechanism.

[0029] Lifting and conversion stage

[0030] When the mechanism as a whole moves to the left to a certain position, the cam follower 19 contacts the height limit block 11. At this time, since the roller of the cam follower 19 contacts the vertical surface of the height limit block 11, as the slider 9 continues to move to the left, the roller of the cam follower 19 will roll upward along the vertical surface of the height limit block 11.

[0031] Because one end of the four connecting rods is connected to the slider 9 by a fixing bolt, and the other end is connected to the lifting plate 14, when the roller of the cam follower 19 rolls upward, the connecting rod 13 will rotate with the axis of the fixing bolt 24 as the center and supported by the bearing 23. This rotational movement causes the lifting plate 14 to rise upward, thereby realizing the movement conversion from horizontal movement to vertical rise. At the same time, since the spring 18 connects the slider 9 and the spring support 17 on the lifting plate 14, an elastic connection system is formed. In the initial state, the spring 18 is in a stretched state, exerting a downward pulling force on the lifting plate 14, and this pulling force causes the lifting plate 14 to fall on the lifting plate limit block 16. When the cam follower 19 contacts the height limit block 11 and begins to roll upward along its vertical surface, the lifting plate 14 begins to rise. At this time, the tension of the spring 18 still exists, which will prevent the lifting plate 14 from rising excessively, so that the cam follower 19 fixedly connected to the front end of the lifting plate 14 will not separate from the height limit block 11, and the cam follower 19 will always be in contact with the height limit block 11, ensuring that the center of the workpiece 8 remains unchanged in the vertical direction, thereby ensuring the stability and accuracy of the workpiece during the rising process.

[0032] Gripping and subsequent transport phase

[0033] The servo motor 6 continues to control the height of the lifting plate 14, so that the air gripper finger 21 enters the inner hole of the workpiece 8, and after the proximity switch 22 senses the workpiece 8, the proximity switch 22 transmits a signal to the controller. The controller ventilates the air gripper 5 through the solenoid valve, and the air gripper 5 clamps the workpiece 8 and grabs it.

[0034] Then, the servo motor 6 drives the slide block 9 to move right again, and the lifting plate 14 descends under the action of the spring 18, and the workpiece 8 is separated from the workpiece positioning plate 15. The air gripper 5 uses the horizontal moving module 4 to transport the workpiece horizontally to the next process position, completing the entire workpiece moving and lifting feeding action.

[0035] The entire working process is achieved through the precise control of the servo motor and the ingenious coordination of various components, so that the workpiece is first moved horizontally and then rises vertically and is transported to the next process. This reduces the additional driving components used for lifting in traditional methods and improves energy utilization efficiency and equipment integration.
