Description

Technical Field

[0001] This utility model relates to the field of bag gripper technology, and in particular to an unloading structure for PLC robot handling. Background Technology

[0002] In the field of industrial automation, PLC (Programmable Logic Controller) controlled robots are widely used in tasks such as material handling, sorting and unloading. In these applications, bag grippers installed at the end of the robot arm are frequently used due to their gentle gripping method and wide applicability.

[0003] However, existing bag-type gripper unloading structures usually use grippers to clamp objects directly. When objects are stacked in multiple layers, in order to limit the gripped layered materials and prevent the upper layer materials from shifting, a pushing component is provided on the opposite side of the grippers. The pushing component drives the pressure plate to squeeze and fix the upper layer materials. Although this method can achieve rapid fixation of materials, since the pressure plate is in direct contact with the materials and applies pressure, it is easy to cause squeezing damage on the top of the materials, affecting the quality and appearance of the materials.

[0004] Therefore, how to design a PLC robot unloading structure that can effectively fix materials and protect the top of the materials from damage has become a technical problem that urgently needs to be solved in the field of industrial automation. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a material unloading structure for PLC robot handling, comprising:

[0007] Fixing plate;

[0008] A clamping structure is used for clamping materials. The clamping structure includes rotating brackets symmetrically arranged at the bottom of a fixed plate. A conveying arm is hinged to the bottom side of the rotating brackets. A drive unit for pushing the conveying arm to rotate is provided on the side of the fixed plate.

[0009] A limiting structure is provided for limiting the top of the material. The limiting structure includes a pushing part symmetrically arranged at the bottom of a fixed plate. A pressure plate is provided at the bottom of the pushing part. A buffer pad is provided at the bottom of the pressure plate. A fixing part is provided at the connection between the buffer pad and the pressure plate.

[0010] Preferably, the pushing part includes a pressing cylinder disposed at the bottom of the fixed plate, and the output end of the pressing cylinder is fixedly connected to the top of the pressure plate.

[0011] Preferably, the fixing part includes:

[0012] A support rod, the end of which is inserted and connected to the top side of the buffer pad;

[0014] A positioning slot block is provided on the top of the pressure plate, and the bottom of the insert block is inserted and connected to the top of the positioning slot block.

[0015] A snap-fit ​​element is provided at the bottom of the cushioning pad, and the snap-fit ​​element is used to snap and fix the bottom of the cushioning pad.

[0016] Preferably, the snap-fit ​​component includes:

[0017] A snap-fit ​​strip, the bottom of which is inserted and connected to the bottom edge of the buffer pad, and the top of which is inserted and connected to the bottom of the pressure plate;

[0018] The snap-fit ​​groove is located at the bottom of the pressure plate and is used for the insertion and positioning of the snap-fit ​​strip.

[0024] This invention features a limiting structure at the bottom of a fixed plate, with a buffer pad at the bottom of the pressure plate in the limiting structure. The fixed part limits and fixes the pressure plate and the buffer pad. Compared to directly using a pushing part to drive the pressure plate to squeeze and fix the upper material, the buffer pad in this design can isolate and protect the top of the upper material, preventing the pressure plate from directly squeezing and damaging the top of the material.
