Description
Technical Field
The invention relates to the technical field of assembly lines of medium and large-sized cabinets, in particular to an assembly line and a turnover trolley of medium and large-sized cabinets such as a combined air conditioning unit.
Background
When the middle-large cabinet body such as a cabinet of a combined air conditioning unit is assembled, assembly line operation is required, a plurality of stations for different assembly operations are arranged in the assembly process after the cabinet body enters an assembly line, and the cabinet body is off line after assembly is finished.
In the prior art, in order to facilitate the transportation and movement of the cabinet 7 during and after the assembly of the large-sized cabinet 7, a generally adopted assembly line is to erect a roller line 9, the roller line 9 can be shown in fig. 1, the roller line 9 is an unpowered roller line, the assembly line starts assembly work after the bottom bracket 8 provided with the cabinet 7 is placed on the roller line 9, the height of the assembly line of the combined air conditioning unit is 400mm, meanwhile, the assembly line roller protrudes out of the platform by 15mm, personnel need to cross over the roller or stand on the roller during operation, after the assembly work is completed on one station, the cabinet 7 is pushed to the next station by assistance of a plurality of personnel, and when the assembled combined air conditioning unit is off line, the transportation needs to be assisted by a forklift.
In the process of implementing the invention, the inventor finds that at least the following problems exist in the prior art:
1. because personnel need to cross over the roller or stand on the roller during operation, and the roller of the assembly line is higher than one end of the platform by a distance, the risk of a slideway exists when the personnel stand or walk over, and potential safety hazards are brought to the operators;
2. the combined air conditioning unit cabinet body is large in size and high in weight, so that the combined air conditioning unit cabinet body is relatively labor-consuming in pushing the unpowered roller line body, needs 2 or more persons for assistance, can be pushed by using a forklift even when the cabinet body is heavy, is generally operated for 30 sections every day in the assembly operation of the combined air conditioning unit cabinet body, reduces the pushing efficiency because the pushing time is about 2 minutes per section on average, and meanwhile, the pushing process also needs to pay attention to the mutual coordination among multiple persons so as to avoid overlarge cabinet body deviation;
3. the height of the production line of the combined air conditioning unit is 400mm, namely the height of the working platform of the staff is about 400mm, various accessories and various assembly tools need to be taken in the assembly process, and the staff need to frequently go up and down the production line every day, so that the labor intensity of the staff is increased, and the assembly efficiency is reduced;
4. because the difference in height between the existing assembly line body and the ground is large, when the cabinet body of the combined air conditioning unit is off line, a forklift needs to be used for auxiliary carrying, but a plurality of assembly lines generally share one forklift in a production workshop, so that the cabinet body needs to wait for the forklift when being off line, the dependence on the forklift is high, and the assembly line operation can be slowed down when waiting for the forklift.
In view of this, how to solve the problems of safety risk, low assembly efficiency, high labor intensity, high dependence on a forklift and the like of operators in assembly line production of medium and large cabinets such as a combined air conditioning unit and the like in the prior art becomes a subject to be researched and solved by the invention.
