Description

Sucking disc grabbing device

Technical Field

The utility model relates to the technical field of grabbing structures, in particular to a sucker grabbing device.

Background

At present, in the production of PVC fitting pipe fittings, products with different types and specifications are mainly produced through an injection molding machine and a mold in an integrated manner, but the sizes and the weights of the products are different, so that the problem that the position drop point and the manipulator load of the grabbing product need to be considered when the products are grabbed each time, the design structure of the manipulator and the sucker on the injection molding machine is different, and only one or two PVC fitting products can be singly applied. When the production type of PVC accessory is changed, just need to change the grabbing structure on the manipulator in step, it is comparatively inconvenient to use.

In the prior art, snatch the structure when the installation, its extension arm is the style of calligraphy and arranges, receives the influence of side direction force easily, leads to the extension arm to take place to shake or swing sideways to influence its firm degree of connection. More importantly, for PVC fittings, it is necessary to grasp the fitting body and the nozzle portion separately, and in the prior art, only a grasping structure for the fitting body is provided, and another grasping structure is not designed for other portions (such as the nozzle).

Disclosure of utility model

The utility model aims to overcome the defects of single pertinence and poor firmness of the existing grabbing mechanism, and provides a sucker grabbing device which grabs PVC fittings through a sucker and a clamping part respectively, can flexibly adjust the position of the sucker and has better adaptability.

The technical scheme adopted by the utility model is as follows: the utility model provides a sucking disc grabbing device, includes interconnect's first perforated plate, second perforated plate and third perforated plate, and the both ends of third perforated plate are connected with first perforated plate, second perforated plate respectively, all are equipped with a plurality of connecting holes that are used for connecting sucking disc subassembly on first perforated plate, second perforated plate and the third perforated plate. In addition, still include the connecting plate, be equipped with the clamping part that can open and shut on the connecting plate, the connecting plate is connected with any one of first perforated plate, second perforated plate and third perforated plate.

The operating principle of the sucker grabbing device is as follows: the three-axis manipulator is arranged on the three-axis manipulator, and the connecting plate is connected with the sliding block on the three-axis manipulator. After the injection molding machine is opened, the three-axis manipulator moves to a material taking position, at the moment, the sucking disc component adsorbs a product, the clamping part simultaneously clamps the water gap, and then the product is sent out of the injection molding machine through the three-axis manipulator. Then, the water gap and the product are sheared by the external shearing equipment, and at the moment, the water gap and the product are respectively fixed by the clamping part and the sucker assembly and cannot fall off. After shearing, the three-axis mechanical arm sends the product to a sorting position, and the sucker component breaks vacuum suction to enable the product to fall off; and then the three-axis manipulator conveys the water gap to another sorting position, the clamping part is opened, and the water gap falls. The utility model can respectively control the dropping positions of the product and the water gap, thereby reducing the sorting strength of workers.
