Description

Clamp for box filling machine Technical Field The utility model relates to the field of box filling machine structures, in particular to a clamp for a box filling machine. Background The box filling machine is widely applied to industries such as food, beverage, medicine, chemical industry and the like, and is used for automatically filling products into cartons, plastic boxes or other transport packages. The existing boxing machine is generally composed of a robot, a control system, a vision system, a clamp and other key parts, and the components work cooperatively to realize efficient and accurate boxing operation. The clamp plays a vital role in the case packer, is a core component of the end effector of the robot, directly contacts with a product and is responsible for grabbing, carrying and releasing the product. The design and performance of the clamp directly affect the efficiency, accuracy and reliability of the case packer. The existing clamp comprises a clamping jaw type clamp, a sucking disc type clamp, a magnetic clamp, a flexible clamp and the like, wherein the clamping jaw type clamp is suitable for products with regular shapes, such as paper boxes, plastic bottles and the like, the clamp can firmly grasp the products through opening and closing actions of mechanical clamping jaws, the sucking disc type clamp is suitable for products with flat surfaces, such as glass bottles, plastic plates and the like, the sucking disc can absorb and lift the products through a vacuum absorption principle, the magnetic clamp is suitable for metal products, such as metal parts, steel bottles and the like, the clamp can rapidly grasp the metal products through magnetic absorption, the flexible clamp is suitable for products with irregular shapes or fragile shapes, such as flexible clamps of fruits, eggs and the like, can adapt to products with different shapes through soft materials or pneumatic devices, and damage is avoided.
