It is the earliest industrial robot and also the earliest modern robot. It plays a very important role in the assembly line operation of automatic packaging.

[0003] At present, when an automatic packing robot encounters a tall object, the mechanical claw is too short in length and has a small force area, so the mechanical claw cannot stably clamp the object. Therefore, a larger mechanical claw needs to be replaced. However, the replacement process of the mechanical claw is cumbersome, time-consuming and labor-intensive, which increases the labor intensity of the staff and affects the convenience of using the automatic packing robot.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1As shown, an industrial robot manipulator for automatic packing includes two support frames 2, and the upper parts of the two support frames 2 that are close to each other are symmetrically fixed with slide rails 3, and the ends of the two slide rails 3 that are close to each other are slidably connected with slide plates 4. The lower ends of the slide plates 4 are fixedly connected with a rotating component 5, and the lower part of the rotating component 5 is fixedly connected with a connecting piece 6, and the lower end of the connecting piece 6 is fixedly connected with a clamping component 7, and the upper end of the slide plates 4 is fixedly connected with a moving component 1.

[0027] During the specific implementation of this scheme, the device is firstly mounted on both sides of the transport device and located in the front of the transport device, and a collection box is placed in front of the transport device. When the transport device transports the object to the front, the moving component 1 can be started to drive the slide plate 4 to move, which can drive the clamping component 7 to move left and right. When the clamping component 7 is located on the upper part of the object, the connecting member 6 can be used to lower the clamping component 7, and during the process of the clamping component 7 being lowered, the clamping component 7 can be started to open and grab the object. After grabbing, the rotating component 5 can be started to drive the connecting member 6 and the clamping component 7 to rotate into the collection box in front, and the boxing can be successfully completed.

[0028] The above-mentioned middle connecting member 6 is composed of an electric telescopic rod and a connecting rod. The electric telescopic rod is fixedly connected to the gear 2 53. The connecting rod and the electric telescopic rod 71 and the two vertical plates 1 72 are all fixedly connected, which is convenient for driving the clamping assembly 7 to move up and down, and the clamped objects leave the transportation device for collection.

[0029] Specifically, in order to enhance the flexibility of the device and improve the efficiency of packing, refer to Figure 2 and Figure 3 The moving assembly 1 includes a screw rod 12, a motor 11 is fixedly connected to the right end of the screw rod 12, and a connecting block 13 is threadedly connected to the outer surface of the screw rod 12;

[0030] For further information, see Figure 2 , the connecting block 13 is fixedly connected to the slide plate 4, the motor 11 is fixedly connected to the support frame 2 on the same side, and the screw rod 12 is rotationally connected to the support frame 2 on the left side;

[0031] For further information, see Figure 2 The rotating assembly 5 includes a second gear 53, the outer surface of the second gear 53 is meshedly connected with the first gear 51, and the lower end of the first gear 51 is fixedly connected with the second motor 52;

[0032] For further information, see Figure 2 , gear 1 51 and gear 2 53 are both rotatably connected to the slide plate 4, motor 2 52 is fixedly connected to the slide plate 4, and connecting member 6 is fixedly connected to gear 2 53;

[0033] It can be seen that after the device is installed, the motor 11 can be started to drive the screw 12 to rotate forward or reversely, which can drive the connecting block 13 to move left or right, so that the slide plate 4 slides between the two slide rails 3, and the other components at the lower end of the slide plate 4 move together until the clamping assembly 7 is located at the upper part of the object, and then the motor 11 can be paused, and the connecting piece 6 and the clamping assembly 7 can be started to clamp the object. After clamping, the motor 2 52 can be started to drive the gear 1 51 to rotate, which can drive the gear 2 53 to rotate together, so that the connecting piece 6 also rotates together, and drives the clamping assembly 7 and the object clamped by it to move to the upper part of the front collection box, and then the clamping assembly 7 can be started to put the object into the collection box, and the packing is completed;

[0034] Then, the rotating component 5 is started again to reset the clamping component 7 and place it at the rear of the device to prepare for the next object. The motor 11 can be started here to drive the slide plate 4 to move left and right, so that the clamping component 7 can clamp the next object. The moving component 1 can be used to clamp objects at any position on the transport device, further improving the practicability of the device.

[0035] Specifically, in order to facilitate the clamping of objects of different heights, refer to Figure 4 and Figure 5 The clamping assembly 7 includes two vertical plates 72 and an electric telescopic rod 71. The electric telescopic rod 71 is fixedly connected to a fixed plate 74 through a piston rod at the output end. The lower ends of the two vertical plates 72 are commonly fixedly connected to a receiving plate 73. The lower end of the fixed plate 74 is fixedly connected to three contraction assemblies 75 in a circular array. The electric telescopic rod 71 and the two vertical plates 72 are fixedly connected to the connecting piece 6.

[0036] For further information, see Figure 5 The retracting assembly 75 includes a connecting rod 751 and two vertical plates 754. The lower parts of the two vertical plates 754 close to each other are connected to an L-shaped rod 753 for rotation. The L-shaped rod 753 and the connecting rod 751 are connected to two centrally symmetrical connecting plates 752 for rotation. The lower part of the outer surface of the L-shaped rod 753 is slidably connected to a clamping claw 756. The end of the clamping claw 756 away from the electric telescopic rod 71 is threadedly connected to a bolt 757.

[0037] For further information, see Figure 5 , the two vertical plates 754 are fixedly connected to the receiving plate 73, the three connecting rods 751 penetrate the lower end of the receiving plate 73 and extend to the lower end of the fixed plate 74 and are slidably connected to the receiving plate 73, the three connecting rods 751 are fixedly connected to the fixed plate 74, and the side where the three clamping claws 756 are close to each other is the concave side;

[0038] When the locking cam 752 is in motion, the locking cam 753 is in motion and the two locking cams 754 are in motion.

[0039] When the object is relatively high, the bolt 757 can be rotated to release the fixation between the L-shaped rod 753 and the clamping jaw 756, and then the clamping jaw 756 can be slid downward to lengthen the overall length of the clamping jaw 756 and the L-shaped rod 753, so as to improve the stability of clamping the relatively high object.

[0040] It should be noted that the specific installation method, circuit connection method and control method of the motor 11, the connecting member 6, the motor 2 52 and the electric telescopic rod 71 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
