Description

Technical Field

[0001] The utility model relates to the technical field of pallet production, in particular to a pallet grabbing device. Background Art

[0002] Pallets are indispensable in the logistics industry. The advantages of plastic pallets are: light, stable, beautiful, good integrity, no nails or thorns, odorless and non-toxic, acid-resistant, alkali-resistant, corrosion-resistant, easy to rinse and disinfect, non-rotten, recyclable, etc.; they are important tools for modern transportation, packaging, and warehousing, and are internationally required to be used for storage in industries such as food, aquatic products, medicine, and chemicals.

[0003] Currently, pallet production is generally semi-automated, requiring operators to manually remove pallets before continuing the next production cycle. This method not only increases the number of operators on the production line, but also increases their workload and labor intensity, thereby increasing production costs and safety risks. Furthermore, semi-automatic production is inefficient and has inconsistent product quality, making production and quality control difficult, thereby increasing management costs.

[0027] like Figures 1 to 4 As shown, during actual use of the present invention, the grabbing mechanism 3 is first moved to the material picking position through the rotating mechanism 1 and the translation mechanism 2, and the pallet is taken out from the injection molding device through the fixed clamping arm 32 and the movable clamping arm 33 on the grabbing mechanism 3. After being taken out, it is transported to the next process through the translation mechanism 2. By replacing manual handling with machinery, the level of production automation is improved, labor efficiency is improved, manufacturing cost is low, and operation is simple and smooth.

[0028] The movement of the grabbing mechanism 3 on the X, Y and Z axes is achieved by the first translation assembly 21, the second translation assembly 22 and the third translation assembly 23. The structure is simple, the subsequent maintenance is convenient, and the equipment use cost is low.

[0029] As a further preferred embodiment, the second translation assembly 22, the third translation assembly 23 and the grasping mechanism 3 are correspondingly arranged in two groups, and the two groups of correspondingly arranged second translation assemblies 22, the third translation assembly 23 and the grasping mechanism 3 are in opposite directions. When one group of the grasping mechanism 3 grasps the pallet, the other group can synchronously place the grasped pallet to the next process. By setting up two groups of grasping mechanisms, the transportation speed of the pallet is improved, thereby improving the production efficiency.
