[0003] At present, a multi-pickup arm robot generally uses a vacuum suction cup to pick up the processed products. When the processed products are picked up by the vacuum suction cup, due to the high pressure inside the vacuum suction cup, the product and the hard parts inside the suction cup will be squeezed, causing damage to the product.

[0004] How to invent a robotic arm with multiple picking arms to improve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content

[0005] In order to remedy the above deficiencies, the utility model provides a robotic arm with multiple picking arms, aiming to improve the problem that when the processed product is picked up by a vacuum suction cup, the product and the hard parts in the suction cup will be squeezed due to the high pressure in the vacuum suction cup, resulting in damage to the product.

[0006] The utility model is achieved in this way:

[0007] The utility model provides a robot arm with multiple picking arms, comprising a base and a robot arranged on the top of the base, and also comprising: a first picking arm and a second picking arm installed at the ends of the robot arm; a mounting rod fixedly connected to the first picking arm and the second picking arm, a vacuum suction cup is installed at the bottom of the mounting rod, a buffer air bag is fixedly connected inside the vacuum suction cup, a buffer pad is fixedly connected to the bottom of the buffer air bag, a connecting hole is opened on the buffer air bag, wherein the buffer air bag is used to provide buffer support for the vacuum suction cup and the product when picking up the product.

[0008] Preferably, a lifting cylinder is installed on the top of the base, an output end of the lifting cylinder is fixedly connected to a mounting plate, and the manipulator is installed on the top of the mounting plate.

[0009] Preferably, it also includes a fixing ring fixedly connected to the mounting rod, a threaded sleeve rotatably connected to the fixing ring, a sealing airbag fixedly connected to the bottom of the fixing ring, wherein the bottom sleeve of the mounting rod is provided with a threaded tube, a sealing groove is opened on the top of the threaded tube, the sealing airbag is adapted to the sealing groove, and the threaded sleeve is connected to the threaded tube by threads.

[0010] Furthermore, a limiting ring is fixedly connected to the inside of the threaded tube, and the top of the limiting ring fits with the bottom of the mounting rod.

[0011] Furthermore, the buffer airbag is fixedly connected to the bottom of the threaded tube, and the vacuum suction cup is installed at the bottom of the threaded tube.

[0012] Preferably, a high-pressure air pipe is installed on the top of the mounting rod, and the mounting rod is configured to be hollow.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model uses a buffer airbag, a buffer pad and a connecting hole in coordination. When a product is picked up by a vacuum suction cup, the pressure of adsorption will be buffered and absorbed by the buffer airbag and the buffer pad due to the reduction of the air pressure in the vacuum suction cup. In the process of buffering and absorption, the pressure in the vacuum suction cup can still be reduced by setting the connecting hole, which ensures the adsorption force while preventing the adsorption force from being too large, causing the hard structure in the vacuum suction cup to hit the product and causing damage to the product, thereby protecting the product well.

[0015] 2. The utility model uses a sealing airbag and a sealing groove in coordination. During the installation of the vacuum suction cup, the sealing airbag will enter the sealing groove, and under the squeezing action of the threaded tube, the sealing airbag can completely fill the sealing groove, thereby ensuring the sealing of the vacuum suction cup installation and ensuring the stability of the movement of the vacuum suction cup when picking up the product.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model.

[0025] When in use, the height of the manipulator 4, the first pick-up arm 5 and the second pick-up arm 6 are adjusted by the lifting cylinder 2, and then the manipulator 4 enables the first pick-up arm 5 and the second pick-up arm 6 to pick up the product through the vacuum suction cup 15. When picking up, the vacuum suction cup 15 is first fitted with the product, and then the air in the vacuum suction cup 15 is extracted through the high-pressure air pipe 8 to reduce the air pressure in the vacuum suction cup 15 so that the vacuum suction cup 15 can adsorb the product. In the process of adsorbing the product, the buffer pad 17 will be fitted with the product, and then in the process of gradually reducing the air pressure in the vacuum suction cup 15, the buffer airbag 16 will be compressed to buffer the adsorption force of the vacuum suction cup 15. When the buffer airbag 16 is compressed, the gas in the vacuum suction cup 15 will be continuously extracted through the connecting hole 18, thereby ensuring that the adsorption force can adsorb the product.

[0026] While ensuring the adsorption force, it prevents the adsorption force from being too large, causing the hard structure in the vacuum suction cup 15 to hit the product and cause damage to the product, thereby well protecting the product.

[0027] Reference Figure 1 , Figure 3 , Figure 4 , further comprising a fixing ring 9 fixedly connected to the mounting rod 7, a threaded sleeve 10 rotatably connected to the fixing ring 9, a sealing airbag 11 fixedly connected to the bottom of the fixing ring 9, wherein a threaded tube 13 is sleeved at the bottom of the mounting rod 7, a sealing groove 12 is provided at the top of the threaded tube 13, the sealing airbag 11 is adapted to the sealing groove 12, and the threaded sleeve 10 is connected to the threaded tube 13 by threads.

[0028] However, due to the long-term use of the vacuum suction cup 15, the vacuum suction cup 15 will be damaged. At this time, the threaded tube 13 is removed by rotating the threaded sleeve 10, and then a new threaded tube 13 is installed. During installation, the threaded tube 13 is inserted at the bottom of the installation rod 7, and then the threaded sleeve 10 is rotated to move the threaded tube 13 upward, so that the sealing airbag 11 enters the sealing groove 12 until the limit ring 14 fits with the installation rod 7, and under the squeezing action of the threaded tube 13, the sealing airbag 11 can completely fill the sealing groove 12, thereby ensuring the sealing of the vacuum suction cup 15 installation and ensuring the stability of the vacuum suction cup 15 in picking up the product.
