Abstract
Description
Technical Field
[0001] This utility model relates to the field of precision shell making technology, and in particular to a high-efficiency shell making production line. Background Technology
[0002] Precision shell making is a crucial step in the precision casting process, primarily used to manufacture high-precision casting shells with high surface quality. Traditional precision shell making production lines mainly consist of two core processes: slurry application and sand application. The slurry application process uniformly coats the workpiece surface with slurry, while the sand application process uses sand to create a uniform sand layer on the shell. Currently, most production lines utilize a single robotic arm as the core handling equipment. The robotic arm picks up the workpiece and sequentially completes the slurry application and sand application processes, finally transferring the workpiece to a transfer car or conveyor line.
[0003] However, existing single-robot production lines have the following technical shortcomings:
[0004] Low production efficiency: Since all handling and processing tasks are completed by relying on only one robot, the robot must perform actions such as slurry application, sanding, and transfer in sequence, resulting in a long processing cycle for each workpiece, which makes it difficult to meet the needs of mass production.
[0005] Uneven equipment utilization: While a robotic arm is performing a certain process (such as slurry application), other equipment (such as a sand-floating machine) may be idle, resulting in a waste of resources. Utility Model Content

The robotic arm module 40 is used to grasp workpieces 80 and can move workpieces 80 to the sanding machine 50 or the transfer and placement rack 30.

[0029] The sand-loading machine 50 adopts an existing floating sand machine, sand-drenching machine, or floating sand-drenching machine.
[0030] Working principle of shell-making production line:
[0031] S1, the robotic arm module 40 grabs the workpiece 80 located on the first conveyor line 60 and moves the workpiece 80 to place it on the transfer rack 30.
[0032] S2, the multi-axis robotic arm 20 grabs the workpiece 80 located on the transfer rack 30 and moves the workpiece 80 to the slurry-coating module 10 for slurry coating. After the slurry coating is completed, the workpiece 80 is put back into the transfer rack 30.

[0034] S4, while waiting for the workpiece 80 to finish floating sand, the robot module 40 grabs the workpiece 80 located on the first conveyor line 60 and moves the workpiece 80 to place it on the transfer rack 30.
[0035] S5, after the workpiece 80 has completed floating / sanding, the robot module 40 grabs the workpiece 80 that has completed floating / sanding and places it on the second conveyor line 70.
