[0018] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Please refer to Figures 1 to 3The terminal grabbing mechanism of the automatic bottle unloading device of this embodiment is used for grabbing a plurality of glass bottles 1 arranged in a row at the same time, comprising a rectangular frame 2, a plurality of groups of bottle grabbing driving devices spaced apart along the length direction of the rectangular frame 2, a plurality of upper beams 3 arranged between each two adjacent groups of bottle grabbing components, and a bottle grabbing component; the bottle grabbing component and the upper beam 3 both span between the two wide sides of the rectangular frame 2, and a connecting piece 31 for assembly with an external device is provided at the upper end of the upper beam 3; the bottle grabbing component comprises a guide rail component 6, a pair of L-shaped clamping jaws 7, and a pair of hollow hoses 8 made of polyurethane material, the pair of L-shaped clamping jaws 7 are arranged with vertical plates opposite to each other and along the length direction of the rectangular frame 2, and the hollow hoses 8 are arranged at the ends of the opposite vertical plates that overhang downward along the full length of the L-shaped clamping jaws 7, and the horizontal plate is connected to the slider of the guide rail component 6, and the pair of L-shaped clamping jaws 7 are driven by the plurality of groups of bottle grabbing driving devices to slide toward each other to close or slide away from each other to open along the width direction of the rectangular frame 2 through the slider along the slide rail of the guide rail component 6;

[0020] When the end grasping mechanism of the automatic bottle unloading equipment is used to grasp the glass bottles 1, a pair of L-shaped clamping claws 7 are symmetrically located on both sides of multiple consecutively arranged glass bottles 1, and the end of the vertical plate surface is at the same height as the bottle mouth of the glass bottle 1. When opened, there is a distance between the glass bottle 1 and the glass bottle 1. When closed, a pair of hollow hoses 8 are used to closely contact the bottle mouths of multiple consecutively arranged glass bottles 1, so as to achieve simultaneous clamping of multiple consecutively arranged glass bottles 1.

[0021] In the specific implementation, the corresponding structural settings also include:

[0022] The connecting piece 31 is an angle code, and the entire mechanism serves as an end effector and is assembled at the end of the robot through the connecting piece 31.

[0023] The bottle grabbing driving device comprises a pneumatic clamping jaw 4 and a connecting plate 5. The extension direction of the pneumatic clamping jaw 4 is arranged along the width direction of the rectangular frame 2. The two clamping jaws are connected to the horizontal plates of a pair of L-shaped clamping jaws 7 through bolts through the connecting plate 5.

[0024] The lower end of the rectangular frame 2 spans across a plurality of lower cross beams 9 along the width direction, and a set of guide rail assemblies 6 is installed on each lower cross beam 9 .

[0025] The upper and lower beams are made of standard aluminum profiles, which are light in weight and high in strength. The guide rail assembly is installed on the lower beam to enhance the bending moment resistance of the mechanism and help improve the stability of the mechanism.

[0026] The pneumatic gripper adopts large-diameter products, which fully utilizes the advantages of large-diameter opening, improves the compatibility with position errors when grasping glass bottles and cans, reduces the difficulty of grasping, and saves control investment.

[0027] The hollow hose 8 is made of polyurethane, which increases the friction between the hose and the mouth of the glass bottle, provides a more reliable clamping force, and utilizes the characteristics of the hose body to provide a buffer during clamping, thereby reducing the impact on the bottle mouth during clamping.

[0028] Working Example:

[0029] Initially, the pneumatic gripper opens, and a pair of L-shaped grippers open with it. The entire mechanism can be driven by the robot to move above the glass bottles and jars arranged in a row on the baking kiln, so that a pair of L-shaped grippers are located outside the two sides of a plurality of continuous glass bottles and jars at the height of the bottle mouth. After that, the pneumatic gripper closes, driving a pair of L-shaped grippers to close under the guidance of the guide rail assembly, and closely contacts the two sides of the bottle mouths of each glass bottle and jar within the length direction of the L-shaped gripper through a pair of hollow hoses, clamping multiple glass bottles and jars at the same time. After that, the robot drives the mechanism and the grasped glass bottles and jars to be lifted as a whole, and moves them to each glass bottle and jar along the conveying direction and falls on the flat top chain. After that, the pneumatic gripper opens again to release the clamping of the glass bottles and jars, and the entire mechanism rises with the robot and detaches from the glass bottles and jars. This cycle is repeated.
