[0002] Since the beginning of the new century, with the rapid development of my country's economy and the rapid improvement of people's living standards, automobiles have become increasingly popular, and the market demand for automobiles has also been growing. Therefore, the production capacity of many car manufacturers is gradually increasing in a planned manner. In the automobile manufacturing process, a large number of sheet metal parts are required. In the production process of automated production workshops, loading devices, such as intelligent robotic arms, are often used to automatically load automotive sheet metal parts from conveyor belts onto worktables.

[0003] However, as is well known, automotive sheet metal parts come in a variety of shapes. Some sheet metal parts are suitable for clamping, while others (raw materials) are suitable for picking up. Therefore, the robotic arms used at different workstations need to be equipped with picking mechanisms suitable for that workstation, thus limiting the scope of use of the robotic arms.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0027] Example:

[0028] like Figure 1-6 As shown, the intelligent loading device for automotive sheet metal parts provided by this utility model includes: a robotic arm 1, which is controlled by an intelligent program. Its structure and principle will not be described in detail here. A composite picking mechanism 2 is installed at one end of the robotic arm 1. The composite picking mechanism 2 includes a connecting cover 20 and a U-shaped support plate 21 installed below the connecting cover 20. The top of the connecting cover 20 is connected and fixed to the robotic arm 1. A suction component is installed on the connecting cover 20, and a clamping component is set on the support plate 21. The suction component can pick up flat sheet metal parts, and the clamping component can clamp sheet metal parts with uneven surfaces. This allows the composite picking mechanism to select a suitable method to pick up the sheet metal parts, and then the robotic arm 1 automatically places the automotive sheet metal parts onto the worktable. Specifically, the suction assembly includes multiple first electric push rods 22 mounted on the connecting cover 20. A suction cup 23 is mounted at the bottom of the first electric push rod 22. The suction cup 23 is an active suction cup that can actively intake and exhaust air, such as the ABB robot suction cup. The first electric push rods 22 control the suction cup 23 to descend. After the suction cup 23 adheres to the surface of the sheet metal part, the suction cup 23 actively extracts air and then uses negative pressure to suck up the sheet metal part. After the sheet metal part is placed on the worktable, the suction cup 23 takes in air and releases the sheet metal part. The clamping assembly includes two clamping plates 24 symmetrically slidably mounted on the bottom of the support plate 21. A second electric push rod 25 is mounted on the outer side of each clamping plate 24 to drive its movement. A clamping block 26 is mounted on the inner side of each clamping plate 24. The size of the clamping block 26 can be adjusted and replaced as needed. In use, the second electric push rod 25 drives the clamping plates 24 inward, causing the two clamping plates 24 to move closer together, clamping the sheet metal part located between them. The clamping block 26 presses against the edge of the sheet metal part, thus picking it up. After the sheet metal part is placed on the worktable, the clamping plates 24 move away from each other, releasing the sheet metal part. It is worth noting that when the clamping assembly and the suction assembly do not operate simultaneously, a suitable picking method should be selected based on the structural characteristics of the sheet metal part.

[0029] By installing a composite picking mechanism 2, including a connecting cover 20, a support plate 21, a suction component, and a gripping component, on the robot arm 1, the robot arm 1 can either pick up the sheet metal parts by suction and place them on the worktable, or it can pick up the sheet metal parts by gripping and place them on the worktable. The robot arm 1 is more flexible and versatile in its use, thus expanding the scope of its application.

[0030] Example 2:

[0031] like Figure 5 As shown, in this embodiment, a clamping part is provided on the side of the clamping plate 24. When the robot selects to pick up the sheet metal part using the suction method, the output shaft of the first electric push rod 22 extends, so that the suction cup 23 is lower than the bottom height of the clamping plate 24. Then, the second electric push rod 25 starts and pushes the clamping plate 24 to move inward. Then, the outer clamping parts of the two clamping plates 24 clamp the output shaft of the first electric push rod 22, which helps to clamp and fix the first electric push rod 22. This prevents the suction cup 23 from becoming unstable after picking up the sheet metal part due to the excessive extension of the output shaft of the first electric push rod 22. This improves the stability of the suction cup 23 and reduces the possibility of the sheet metal part falling off due to shaking.

[0032] By providing a clamping part on the side of the clamping plate 24, the first electric push rod 22 can be auxiliaryly fixed by the clamping plate 24, which can improve the stability of the suction cup 23 during use.

[0033] Example 3:

[0034] like Figure 5 As shown, in this embodiment, a shim 27 is fixedly installed on the inner side of the clamping part. During use, the shim 27 rests on the output shaft of the first electric actuator 22, reducing the possibility of damage to the output shaft. This helps to improve the service life of the first electric actuator 22.

[0035] By fixing a shim 27 to the inside of the clamping part, the crushing damage to the first electric push rod 22 can be reduced, which helps to improve the service life of the first electric push rod 22.

[0036] Example 4:

[0037] like Figure 6 As shown, in this embodiment, a track 29 is installed on the support plate 21, and a slider 28 is slidably installed on the track 29. The slider 28 is fixedly connected to the top of the clamping plate 24. Therefore, when the clamping plate 24 moves, it drives the slider 28 to move along the track 29. The movement stability of the clamping plate 24 is improved by the support of the track 29 and the slider 28.

[0038] By setting the track 29 and the slider 28, the movement stability of the clamp 24 is improved.

[0039] Example 5:

[0040] like Figure 6 As shown, a clearance hole 30 is provided on the support plate 21. When in use, a part of the slider 28 can pass through the clearance hole 30, thereby increasing the maximum distance between the two clamping plates 24, increasing the maximum clamping width of the sheet metal parts, and thus increasing the application range of the clamping assembly.

[0041] By opening clearance holes 30 on the support plate 21, the usability of the clamping assembly can be increased.

[0042] Example 6:

[0043] like Figure 4 and Figure 6 As shown, an image recognition component 31 is installed on the side of the connecting cover 20. The image recognition component 31 is connected to the intelligent control console of the robot arm 1. The main function of the image recognition component 31 is to capture image information of the sheet metal parts on the conveyor belt, intelligently analyze the type code of the sheet metal parts, and screen and compare it according to the type code library stored in the database to finally determine the specific model of the sheet metal parts. Then, the model information is sent to the intelligent control console of the robot arm 1. The intelligent control console selects an appropriate picking method to pick up the sheet metal parts according to the model of the sheet metal parts. At the same time, it should be noted that multiple cameras should be installed at the front end of the robot arm 1 to identify the orientation and distance of the sheet metal parts.

[0044] By installing an image recognition component 31 on the side of the connecting cover 20, it is possible to easily perform intelligent recognition of sheet metal parts.

[0045] Working principle: When in use, the appropriate method of use is adopted according to the shape of the sheet metal part.

[0046] Clamping method: The second electric push rod 25 drives the clamping plate 24 to move inward, so that the two clamping plates 24 come closer to each other and clamp the sheet metal part located between the two clamping plates 24. The clamping block 26 presses against the edge of the sheet metal part, and then picks up the sheet metal part. After the sheet metal part is placed on the worktable, the clamping plates 24 move away from each other and release the sheet metal part.

[0047] Suction method: The first electric push rod 22 controls the suction cup 23 to descend. After the suction cup 23 is attached to the surface of the sheet metal part, the suction cup 23 actively draws air and then uses negative pressure to suck up the sheet metal part. After the sheet metal part is placed on the worktable, the suction cup 23 takes in air and releases the sheet metal part.
