Description

Technical Field

[0001] This utility model relates to the field of injection molding product clamping technology, and in particular to a robotic arm for gripping and protecting products. Background Technology

[0002] During the development of fully automated production in the gas and pipe fittings workshop, which integrates injection molding machines with a six-axis robotic arm for automatic part handling, two common gripping modes of the robotic arm were found: 1. Using grippers to hold the runner rod. Due to the large weight of the product, significant deformation occurs at the joint between the runner rod and the product. 2. After the injection molding machine ejects, the product is caught in a hopper. The product tumbles inside the hopper, and the runner rod may be supported at the bottom of the hopper, causing stress at the joint between the runner rod and the product. Furthermore, the high temperature of the product immediately after exiting the mold makes it more prone to stress deformation. These two methods are effective for gripping small products and products of half their weight. However, when dealing with heavy and hot products, the large weight and high temperature often lead to significant deformation, damaging the joint between the product and the runner rod and affecting product quality. Utility Model Content

[0003] To address the aforementioned problems, this utility model aims to provide a protective tooling for robotic arms when gripping products, thereby solving the problem that the area where the product and the flow channel rod meet during gripping is prone to deformation due to its heavy weight and high temperature.
