Description
Technical Field
The invention relates to the technical field of automobile radiator assembly, in particular to a radiator core assembly machine and an assembly method thereof.
Background
Because of the rapid introduction of pure electric buses, manufacturers producing radiators at present only use the production experience of commercial vehicle radiators. For the individual requirements of the passenger car radiator, the improvement of the related production process is only in the fumbling stage, and no related national standard or industry standard exists at all. According to the experience of the two years of new energy passenger car radiator production of our company, the requirements of the passenger car on the radiator, both in terms of heat radiation performance and product reliability, are far higher than those of commercial vehicles. The traditional production equipment and production process can not meet the requirements of new energy buses on the radiator.
The radiator core assembly machine used by companies at present has the same problems that the assembly process is complex, time-consuming and material-consuming, and the quality cannot be ensured:
firstly, the radiator core assembled according to the production process set by the existing assembly machine has the quality problems of uneven wave band, band dropping, inclined brace holes and the like. The main reasons are that the working assembly machines for assembly, leveling, correction and the like cannot guarantee that the working assembly machines can only be completely finished by manual work, visual control is performed, the product quality cannot be stable, and the working efficiency is low.
Secondly, the traditional assembly machine workflow is as follows:
s101, arranging a radiating belt, radiating pipes and baffles according to the requirements of a drawing by an assembly machine;
s102, flattening and finishing the core body;
s103, binding and fixing the assembled core body by using iron wires;
s104, loosening an air cylinder of the assembly machine and taking down the core body;
s105, knocking out a main piece;
s106, taking down the iron wires bound for the first time;
s107, secondary flattening of the core body and arrangement of the heat dissipation belt;
s108, correcting positions of the baffle and the core body;
s109, bundling the corrected core body with iron wires for the second time;
step S110, the flow goes to a roasting process.
The 18 minutes required to complete a core according to the above procedure is very inefficient and presents the first quality problem.
In addition, the original assembly machine backboard is a whole board, and the relative positions of the baffle plate, the radiating belt and the radiating pipe of the assembled radiator core body cannot reach the positions required by the drawing. Firstly, according to the technical requirements of products, the baffle, the radiating pipe and the radiating belt are not on the same plane, the radiating belt exceeds the radiating pipe by 1mm, the relative positions of the baffle and the radiating belt are on the same central line, and the fact that the relative positions of the braces on the baffle and the radiator core are equal is satisfied. However, the core body actually assembled often cannot be marked, one surface of the heat dissipation belt, which is close to the back plate, of the heat dissipation pipe is almost on the same plane, the core body needs to be taken down and then is completely manually flattened, and the distance of the heat dissipation belt, which is higher than the heat dissipation pipe by 1mm, cannot be ensured by visual inspection. Secondly, the baffle position and the radiating pipe and one surface of the radiating belt backboard are basically on the same plane, so that the relative positions of the brace arranged on the baffle and the core body of the radiator are not consistent, and the serious surface is directly pressed on the core body.
