Description

Technical Field

[0001] The invention belongs to the technical field of furniture processing, and in particular relates to an automatic assembly machine system for drawer panels. Background Art

[0002] Door structure products are common products in the furniture industry. There are traditional doors and drawer panels with similar structures. The assembly of drawer panels includes the assembly of vertical bars, cross bars, and core boards. During the assembly process, glue needs to be applied along the notches inside the cross bars, and glue needs to be applied inside the holes and notches inside the vertical bars. The assembly process is to combine the vertical bars, cross bars, and core boards that have been glued. The assembly of the vertical bars and core boards, and the cross bars and core boards requires the core boards to be inserted into the notches of the cross bars and vertical bars. The assembly of the vertical bars and cross bars requires the wooden tenons of the cross bars to be inserted into the corresponding holes of the vertical bars and fit tightly. At present, the assembly of this type of product mainly relies on manual work, and a small number of them are also processed by equipment. However, whether it is manual or automatic assembly, the dispensing process is an obvious constraint.

[0003] Manual assembly and manual gluing impose a heavy burden on workers, and we cannot try to increase the workload. The efficiency is also low. Automatic assembly, because the gluing process is integrated on the assembly machine, occupies most of the door assembly time. A small part even requires manual pre-assembly, which seriously restricts the speed of production. In addition, since automatic assembly is continuous loading, it is difficult to determine whether the workpiece in the machine has glue, and it needs to be disassembled after assembly is completed to determine. Therefore, in terms of glue control, once the gluing device is abnormal, the product has a huge risk of glue leakage. At present, whether it is automatic or manual assembly of doors, the normal efficiency is about 5 pieces / minute, and the assembly efficiency is low. Therefore, in order to solve the above problems, it is necessary to develop a new type of drawer panel automatic assembly machine system. Summary of the invention
