[0024] The adaptability assembly includes an adaptability tube 501 fixedly connected to the side of the L-shaped plate 4 near the suction cup 105. The adaptability tube 501 is connected to the adaptability plate 502 via a first guide assembly. The adaptability plate 502 is fixedly connected to the side near the suction cup 105 with an adaptability rod 503. The other end of the adaptability rod 503 is rotatably connected to the mounting base of the suction cup 105 via a connecting ball 504. A spring 505 is provided on the side of the adaptability plate 502 away from the adaptability rod 503. The other end of the spring 505 is connected to the bottom wall of the adaptability tube 501.

[0025] It should be noted here that: by adapting the setting of the component, the suction cup 105 can easily change its position according to the surface shape of the automobile part, thereby helping to improve the sufficiency of the contact between the suction cup 105 and the complex shape of the surface of the automobile part compared to the existing technology, and then improve the balance of the suction force of the four suction cups 105 on the surface of the automobile part, thereby improving the stability of grasping the automobile parts. At the same time, with the cooperation of the locking component, the shaking of the suction cup 105 during the grasping of the automobile parts due to the elastic connection is reduced, thereby improving the firmness and safety of grasping the automobile parts.

[0026] It is worth noting that the horizontal movable frame 102, the longitudinal movable frame 103 and the vertical movable frame 104 form a three-dimensional movable frame, which can enable the suction cup 105 to move left and right, front and back and up and down.

[0028] It should be noted that the air pipe 6 is provided to adjust the air pressure of the suction cup 105, thereby achieving the grasping and releasing of automobile parts.

[0029] See also Figure 5 The first guide assembly shown in the figure includes two symmetrical guide holes 701 opened on the side wall of the adaptation tube 501. The two guide holes 701 are slidably connected to the guide plates 702. The opposite ends of the two guide plates 702 are connected to the adaptation plate 502.

[0030] It should be noted here that the first guide assembly is provided to provide guidance and limiting functions for the movement of the adaptation rod 503 .

[0031] See also Figure 3-Figure 5 The locking assembly shown in the figure includes two sliding plates 801 slidably connected between the two adjusting aluminum profiles 3. The two sliding plates 801 are connected to a locking plate 802 on the side away from each other through a second guide assembly. The four locking plates 802 are slidably connected to the adaptable tube 501 through the second guide assembly. The vertical movable frame 104 is provided with a driving assembly for driving the four locking plates 802.

[0032] It should be noted here that the locking assembly is used to lock the adaptation rod 503, thereby maintaining the position of the adaptation rod 503 during the grasping process, thereby reducing the shaking of the suction cup 105 during the grasping of automobile parts due to the elastic connection.

[0033] It is worth noting that the locking plate 802 is connected to the adaptable tube 501 via the second guide assembly, so that the locking plate 802 can slide but will not separate from the adaptable tube 501, thereby facilitating the adjustment of the adaptable tube 501.

[0034] See also Figure 4 and Figure 5 The second guide assembly shown in the figure includes a dovetail groove 901 formed on a side of the sliding plate 801 close to the two locking plates 802. The dovetail groove 901 is slidably connected to the two dovetail plates 902. One end of the two dovetail plates 902 is connected to the locking plates 802. A bolt for locking the dovetail plates 902 is threadedly connected to the side of the sliding plate 801 away from the locking plates 802.

[0035] It should be noted here that the second guide assembly is provided to provide guidance and limiting functions for the movement of the locking plate 802 .

[0036] Working Principle: On an automotive parts production line, when an automotive part needs to be grabbed, first, the two adjustment aluminum profiles 3 and four L-shaped plates 4 are moved according to the actual size of the automotive part. The adjustment aluminum profiles 3 and L-shaped plates 4 are then locked with bolts to adjust the spacing between the four suction cups 105. After the spacing between the four suction cups 105 is adjusted, the four suction cups 105 are moved to the top of the automotive part by the horizontal moving frame 102 and the vertical moving frame 103.

[0037] When the four suction cups 105 are moved above the auto parts, the vertical moving frame 104 drives the suction cups 105 to move close to the auto parts. When the four suction cups 105 are in contact with the surface of the auto parts, if the surface of the auto parts has irregular shapes such as curved surfaces, concave and convex structures, the elastic contraction of the adapting components and the rotation of the connecting balls 504 will cause the suction cups 105 to change their positions according to the surface shape of the auto parts. This helps to improve the contact between the suction cups 105 and the complex shapes of the auto parts compared to the existing technology. , thereby improving the balance of the suction force of the four suction cups 105 on the surface of the automobile parts, thereby improving the stability of grasping the automobile parts. After the four suction cups 105 are in contact with the surface of the automobile parts, the air pressure of the suction cups 105 can be reduced by an external air pump, so that the suction cups 105 and the surface of the automobile parts are attracted to each other. At this time, the automobile parts can be grasped to the next station or placement frame under the cooperation of the vertical movable frame 104, the longitudinal movable frame 103 and the horizontal movable frame 102, thereby completing the grasping operation of the automobile parts.

[0038] After the four suction cups 105 are in contact with the surface of the automobile parts, the driving assembly is used to push the locking plate 802 on one side of the sliding plate 801 to contact the surface of the adaptation rod 503, thereby locking the adaptation rod 503, thereby maintaining the position of the adaptation rod 503 during the grasping process, thereby reducing the shaking of the suction cup 105 during the grasping of automobile parts due to the elastic connection, thereby improving the firmness and safety of grasping automobile parts.

[0039] Example 2

[0040] See also Figure 3 and Figure 6, this embodiment further explains Example 1. The driving assembly in the figure includes a motor 1001 fixedly connected to the end of the vertical movable frame 104 close to the suction cup 105. The output end of the motor 1001 is fixedly connected to a rotating frame 1002. The driving plate 1003 is slidably connected to the opposite ends of the rotating frame 1002. The rotating frame 1002 is threadedly connected to two T-shaped tightening rods 1005 for tightening the driving plate 1003. The two sliding plates 801 are fixedly connected to a connecting plate 1004 on one side close to the motor 1001.

[0041] It should be noted here that: through the setting of the drive component, when the motor 1001 drives the rotating frame 1002 to rotate, the two drive plates 1003 will be driven to rotate synchronously. When the two drive plates 1003 rotate to abut against the connecting plate 1004, the two connecting plates 1004 will be pushed away from each other under the driving force, and then the locking plate 802 on one side of the sliding plate 801 will be pushed against the side wall of the adaptation rod 503. At the same time, the T-shaped clamping rod 1005 is used to adjust and lock the drive plate 1003, so that the two drive plates 1003 can adapt to the push of the two connecting plates 1004 with different spacings.
