[0033] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0034] like Figure 1 and Figure 2 As shown, the robot arm 100 includes: a robot arm base 20, a robot arm 30, an anti-slip receiving block 40 and an anti-slip block 50.

[0035] The robot arm base 20 is used to fix the robot arm 30 and carry the robot arm 30 to move.

[0036] The robot arm 30 is used to carry the object to be transferred, and one end of the robot arm 30 is fixed on the robot arm base 20. In a specific example, the number of the robot arm 30 on the robot arm base 20 is at least one.

[0037] Combination Figure 2 and Figure 3 As shown, the anti-skid receiving block 40 is detachably connected to the upper surface of the mechanical arm 30; a groove 41 is provided on the upper surface of the anti-skid receiving block 40. In a specific example, the number of anti-skid receiving blocks 40 on each mechanical arm 30 is at least three; each anti-skid receiving block 40 is provided with at least three grooves 41, and each groove 41 is correspondingly provided with an anti-slip block 50. This improves the reliability of smoothness and anti-skid.

[0038] like Figure 4 and Figure 5 As shown, the anti-sliding block 50 includes a positioning portion 51 and a protruding portion 52; the anti-sliding block 50 is positioned in the groove 41 by interference fit through the positioning portion 51; the protruding portion 52 protrudes from the upper surface of the anti-sliding receiving block 40 to support the conveyed object. In addition, the material of the anti-sliding block 50 is elastic material.

[0039] It is understandable that the anti-sliding block 50 may be spherical (see Figure 4 and Figure 5 ), columnar (see Figure 2 ), a rectangular parallelepiped, or other special shapes, as long as the functionality of the positioning portion 51 and the protruding portion 52 is met. This application does not make any specific restrictions on this.

[0040] In the embodiment of the present application, the robot arm 100 may be a robot arm for conveying a display panel or a semi-finished display panel. It is understandable that the display panel may be a display panel such as a liquid crystal panel, an OLED (Organic Light-Emitting Diode) panel, etc.; the semi-finished display panel may be a semi-finished panel in the manufacturing process such as a glass cover plate, a TFT (Thin Film Transistor) glass, a touch screen functional glass, etc., and the present application does not impose any specific restrictions on this.

[0041] It should be noted that the robot arm 100 can also be used to pick up and place other conveyed objects besides display panels and display panel semi-finished products, and this application does not impose any specific restrictions on this.

[0042] Before using the robot arm of the embodiment of the present application, the anti-sliding block is installed in the groove corresponding to the anti-sliding receiving block, so that the anti-sliding block is positioned in the groove by the positioning portion with interference fit, and the protruding portion protrudes from the upper surface of the anti-sliding receiving block; and the anti-sliding receiving block is detachably connected to the upper surface of the robot arm through a threaded connection or a snap connection, and it is ensured that the highest point of the protruding portion of the anti-sliding block on the entire robot arm is on the same horizontal plane or an approximately horizontal plane. At this time, the robot arm can enter the waiting state for transmission.

[0043] For the application scenario where a robot arm picks up and places an object to be transported, in the working state, the object to be transported is placed on the robot arm, and the robot arm contacts the lower surface of the object to be transported through the protruding part of the elastic anti-sliding block, carrying the transmission of the object until the object is taken down. In this way, it can not only ensure the safe and stable transportation of the object to be transported, but also does not affect the bearing strength, which helps to increase the service life of the robot arm, and the maintenance operation is convenient and time-saving, which is conducive to improving production efficiency and reducing costs.

[0044] In the embodiment of the present application, the anti-slip block 50 is preferably made of rubber material to ensure high elasticity and light weight. The anti-slip receiving block 40 is preferably made of carbon fiber material. It is understandable that the anti-slip block 50 and the anti-slip receiving block 40 can also be made of other applicable materials, and the present application does not make specific restrictions on this.

[0045] In the embodiment of the present application, the main body contour of the anti-sliding block 50 is preferably a sphere or an ellipsoid to improve the convenience of loading and unloading during maintenance.

[0046] Alternatively, if Figure 5 As shown, a platform structure 53 is cut on the anti-sliding block 50; in the load-bearing state, the conveyed object is placed on the robot arm 30 by contacting the platform structure 53. Further, the diameter range of the platform structure 53 is preferably 0.1cm-0.5cm. The platform structure 53 can increase the contact area with the conveyed object, which helps to further improve the reliability of safe and stable transportation.

[0047] In the embodiment of the present application, the diameter of the anti-sliding block 50 ranges from 2 cm to 10 cm, so as to take into account both high universality and applicability.

[0048] In the embodiment of the present application, the anti-slip receiving block 40 is preferably positioned on the upper surface of the robotic arm 30 by a snap connection or a threaded connection to improve the convenience of loading and unloading the anti-slip receiving block 40.
