Description

Technical Field

[0001] The utility model relates to the technical field of manipulators, especially an adsorption type die material taking manipulator. Background Art

[0002] Injection molds are widely used in the production of plastic products. For some thin and long plastic products, due to their thin wall thickness, when the existing material taking manipulator clamps the products from the mold, the pressure exerted on the products by the clamping arms is relatively large when clamping the products, which easily causes the products to deform, resulting in a high defective rate of the products and a large amount of waste. In addition, due to the long and thin products, long clamping arms need to be made, resulting in the manipulator being heavy and affecting the material taking accuracy. Summary of the Invention

[0003] The problem to be solved by the utility model is to provide an adsorption type die material taking manipulator to avoid product deformation and improve material taking accuracy.

[0004] To solve the above technical problem, an adsorption type die material taking manipulator provided by the utility model comprises a rotating device, a connecting plate and a material taking mechanism. The rotating device comprises a cylindrical outer shell, a movable shaft and a gear plate. The movable shaft is movably arranged inside the cylindrical outer shell. The gear plate comprises a mounting bottom plate and a gear body integrally die-cast. The outer edge of the gear body is distributed with teeth. An avoidance groove is arranged at one end of the cylindrical outer shell. The gear body is hinged in the avoidance groove. A rack is connected to one end of the movable shaft. The rack is meshed and connected with the teeth. The mounting bottom plate is fixedly connected to one end of the connecting plate. The material taking mechanism comprises a mounting plate fixedly connected to the other end of the connecting plate and a plurality of material taking modules arranged in parallel on the mounting plate. Each material taking module comprises two adsorption components arranged in parallel. Each adsorption component comprises a connecting pipe, an air connection head connected to one end of the connecting pipe, an upper positioning piece fixedly connected to the connecting pipe, a lower positioning nut threadedly connected to the connecting pipe, a movable piece sleeved on the connecting pipe and movable on the connecting pipe, a vacuum suction head fixedly connected to the bottom of the movable piece, and a buffer spring sleeved on the connecting pipe and abutted between the lower positioning nut and the movable piece. A through hole matching with the connecting pipe is arranged through the mounting plate. The connecting pipe is arranged in the through hole. The upper positioning piece and the lower positioning nut respectively abut against the top surface and the bottom surface of the mounting plate.

[0005] The beneficial effects of the present utility model are as follows: The present utility model provides an adsorption-type mold material-taking manipulator. The movable shaft can be driven by a cylinder to move inside the cylindrical housing. The rack will drive the gear plate to rotate, and the rotating gear plate will drive the mounting plate to rotate, so as to drive the fixture to enter and exit the mold. After the fixture enters the mold, each material-taking module corresponds to each cavity in the mold. The vacuum suction heads of the two adsorption components of each material-taking module are respectively located at both ends of the product. The air connection head is connected to the vacuum air pipe. When the vacuum suction head contacts the product surface, the movable piece will move along the connecting pipe and compress the buffer spring, which can play a buffering role to avoid damaging the product surface by the vacuum suction head. The two vacuum suction heads on both sides will respectively adsorb both ends of the product. By driving the mounting plate to rotate, the product can be taken out of the mold, avoiding pinching the product and preventing the product from deforming, improving the product qualification rate, reducing the load of the manipulator, and improving the material-taking accuracy.
