Description

Technical Field

[0001] The present invention relates to the technical field of stamping equipment, and in particular to a high-speed transporting robot and a transporting method suitable for large press spacing. Background Art

[0002] In traditional stamping production lines, the distance between presses is often large, and there are two production forms. One is to manually carry stamped parts, which is time-consuming, labor-intensive, and also poses a safety hazard; the other is to configure a truss robot in front and behind each press, and the two robots are transported at fixed points through a conveying device to realize an automated production mode. In view of safety, efficiency and other considerations, traditional stamping production lines are facing the need for technological iteration.

[0003] Automated stamping and handling robots can realize the mechanization and automation of production. Existing automated stamping and handling robots are generally equipped with a three-axis moving mechanism. The three-axis moving mechanism is generally composed of drive components such as a motor, a screw rod or a motor, a rack, etc. At the same time, the robot is slidably set on a slide rail, thereby realizing the movement of the robot and precise positioning after movement.

[0004] In traditional production lines with large press spacing, the spacing between adjacent presses is large, and the installation and working space is limited. The existing automated stamping and handling robots are suitable for limited production line spacing and are difficult to be directly applied to the automation transformation of production lines with large press spacing. In addition, due to the limitations of their driving structure and method, the handling speed of existing automated stamping and handling robots is limited, and the maximum speed is generally double speed, which cannot meet the needs of large-spacing and high-beat automated production; in addition, the existing automated stamping and handling robots are very likely to be damaged by contact and impact with materials when moving at high speed to pick up materials.

The first synchronous belt is fixedly installed at both ends of the upper arm after passing around the first driving wheel. The first driving wheel can be used to drive the first synchronous belt to rotate, and then the upper arm can be driven by the first synchronous belt to move laterally along the second slide rail. The transmission efficiency is high and the accuracy of the lateral movement of the upper arm can be controlled more accurately.

[0010] Preferably, the second synchronous belt drive assembly includes a second driving wheel driven by the motor, and the second synchronous belt is meshed with the surface of the second driving wheel.

At the same time, it also enhances the load capacity of the manipulator. In situations where the load is heavy and high-precision operations are required, the setting of the cylinder balancer can effectively share the load pressure of the manipulator, improve its stability and operating efficiency, and play a role in buffering and shock absorption. The telescopic end of the cylinder balancer can absorb part of the impact force or vibration energy to protect the manipulator from damage and improve operating accuracy.

Driven by the second synchronous belt, the third slider starts to move along the third slide rail, so that the movement speed of the third slider is twice that of the upper arm;

[0017] During the movement of the boom, the second driving wheel synchronously drives the second synchronous belt to rotate around the first driven wheel. At this time, the moving speed of the third slider is greater than twice the moving speed of the boom to quickly adjust the left and right position of the end picker assembly.

[0018] Preferably, when the moving speed of the end picker assembly is required to be four times the moving speed of the boom, the first driving wheel and the third driving wheel are started synchronously, the first synchronous belt drives the boom to slide, the sliding of the boom causes the second synchronous belt to rotate around the first driven wheel, and the third slider starts to move along the third slide rail, so that the moving speed of the third slider is twice the moving speed of the boom.

The sliding of the mounting frame 32 causes the fourth synchronous belt 35 to rotate around the second driven wheel 36, thereby driving the fifth slider 38 installed under the fourth synchronous belt 35 to move along the fifth slide rail 37, and the moving speed of the fifth slider 38 is twice the moving speed of the mounting frame 32.

[0048] Through the coordinated use of the first lateral speed-double moving mechanism 3 and the second lateral speed-double moving mechanism 4, a transport speed of four times the speed+ is achieved, and a high beat is achieved, which meets the urgent demand for high beat in the stamping automation industry. The moving parts are driven by synchronous belts, which not only ensures precise transmission but also has a certain flexibility, which can reduce the contact impact between the end picker assembly 39 and the sheet material when picking up the material, and at the same time reduce the degree of damage caused by interference and collision with the mold in accidental situations.

[0049] Example 2

[0050] In a typical embodiment of the present invention, a transport method is proposed, which uses the high-speed transport manipulator suitable for large press spacing in Example 1. The working principle of the high-speed transport manipulator is as follows: Figure 9 As shown, the specific process of the transportation method is as follows:

[0051] When transporting parts, the manipulator is fixedly connected to the frame 1 through the first mounting plate 8, and the vertical movement motor 40 is started, so that the vertical movement motor 40 drives the input shaft of the reducer 13 to rotate, and the output shaft of the reducer 13 drives the gear 12 to rotate. Through the engagement between the gear 12 and the rack 11, the vertical beam 5 moves up and down along the first slide rail 9, thereby adjusting the up and down position of the end picker assembly 39;

[0052] When the vertical position adjustment of the end tooling assembly 39 is completed, under the action of the first synchronous belt driving assembly 18, the first driving wheel 183 drives the first synchronous belt 19 to rotate, and the first synchronous belt 19 drives the upper arm 16 to slide along the second slide rail 26, thereby driving the second synchronous belt 23 wound around the first driven wheel 25 to rotate. Driven by the second synchronous belt 23, the third slider 28 begins to move along the third slide rail 27, so that the movement speed of the third slider 28 is twice the movement speed of the upper arm 16;

[0053] When further speed increase is required, during the movement of the boom 16, the second driving wheel 223 synchronously drives the second synchronous belt 23 to rotate around the first driven wheel 25. The setting of the first driven wheel 25 can keep the second synchronous belt 23 in a taut state, thereby driving the third slider 28 connected to the second synchronous belt 23 to continue to move along the third slide rail 27, so that the left and right position of the end tool assembly 39 can be quickly adjusted. At this time, the moving speed of the third slider 28 is twice the moving speed of the boom 16 (up to three times the speed). The first drive motor 181 and the second drive motor 221 are started at the same time and the output shafts of the two motors rotate in opposite directions, so that the moving speed of the third slider 28 is greater than twice the moving speed of the boom 16, so that the left and right position of the end tool assembly 39 can be quickly adjusted.

[0054] While the first synchronous belt drive assembly 18 and the second synchronous belt drive assembly 22 are working synchronously, the third synchronous belt drive assembly 29 is started, and the third synchronous belt 31 drives the mounting frame 32 installed under the fourth slider 33 to slide along the fourth slide rail 34. The sliding of the mounting frame 32 causes the fourth synchronous belt 35 to rotate around the second driven wheel 36, thereby driving the fifth slider 38 installed under the fourth synchronous belt 35 to move along the fifth slide rail 37, so that the moving speed of the fifth slider 38 is twice the moving speed of the mounting frame 32. Through the joint operation and coordination of the first horizontal speed-multiplying moving mechanism 3 and the second horizontal speed-multiplying moving mechanism 4, specifically the joint operation of the first synchronous belt drive assembly 18, the second synchronous belt drive assembly 22, and the third synchronous belt drive assembly 29, a conveying speed of four times the speed + can be achieved, so that the left and right positions of the end picker assembly 39 can be adjusted at high speed to meet the conveying requirements of large spacing and high beat.

[0055] In other operations, when the moving speed of the end picker assembly 39 is required to be four times the moving speed of the arm 16, the first drive motor 181 and the third drive motor 291 are started synchronously. At this time, under the action of the first drive motor 181, the first driving wheel 183 drives the first synchronous belt 19 to rotate, and the first synchronous belt 19 drives the arm 16 to slide along the second slide rail 26, thereby driving the second synchronous belt 23 wound around the first driven wheel 25 to rotate. Driven by the second synchronous belt 23, the third slider 28 starts to move along the third slide rail 27, so that the movement of the third slider 28 is The moving speed is twice the moving speed of the upper arm 16. At the same time, under the action of the third drive motor 291, the third synchronous belt 31 drives the mounting frame 32 installed under the fourth slider 33 to slide along the fourth slide rail 34. The sliding of the mounting frame 32 causes the fourth synchronous belt 35 to rotate around the second driven wheel 36, thereby driving the fifth slider 38 installed under the fourth synchronous belt 35 to move along the fifth slide rail 37, so that the moving speed of the fifth slider 38 is twice the moving speed of the mounting frame 32, thereby making the moving speed of the end picker assembly 39 four times the moving speed of the upper arm 16.

[0056] This embodiment uses the first synchronous belt drive assembly 18, the second synchronous belt drive assembly 22 and the third synchronous belt drive assembly 29 to adjust the handling speed of the end picker assembly 39 as needed, so that it can be adjusted to double speed +, four times speed and four times speed + relative to the moving speed of the arm 16 to meet the needs of different working conditions.
