Description

Technical Field

[0001] This utility model relates to the technical field of three-way catalytic converter packaging equipment, and more specifically, it relates to a rapid changeover system for three-way catalytic converter packaging. Background Technology

[0002] As a crucial component of modern automotive exhaust purification systems, the encapsulation process in the manufacturing of three-way catalytic converters is of paramount importance. This process involves precisely pressing a package consisting of a carrier and a gasket into the housing to ensure catalytic conversion efficiency and structural stability. Currently, the encapsulation process for three-way catalytic converters commonly employs press-fitting equipment, which integrates key components such as a press-fitting machine, a filter cartridge, and a press-fitting cylinder. The positioning mold in the press-fitting cylinder and housing positioning assembly, as a key component adaptable to different models of three-way catalytic converters, directly impacts the efficiency and adaptability of the production line due to its design flexibility.

[0003] However, in actual production, the existing changeover process is particularly cumbersome in the face of the increasingly diverse market demand for three-way catalytic converters. Traditional methods require operators to manually disassemble and replace the press-fit cylinder and positioning mold. Since the press-fit cylinder and positioning mold are heavy, they put a certain burden on the workers. Moreover, the molds are of high precision, and workers are prone to bumping or dropping them during handling, causing damage to the molds, increasing costs, and easily delaying the production schedule.

[0004] In view of the above problems, the market urgently needs a rapid changeover system for three-way catalytic converter packaging that can improve changeover efficiency and reduce human error. Utility Model Content

[0023] In the initial state, the initial pressing cylinder is inserted into the pressing machine and fixed by a fastening structure. During the changeover, a new pressing cylinder is pre-positioned on the pressing cylinder storage rack. The drive motor 3021 in the rotating assembly 3 is started, causing the rotating shaft 303 to rotate. This, in turn, causes the second pneumatic gripper 102 to move towards the pressing cylinder storage rack. The first lateral movement assembly 4 is then started, causing the second pneumatic gripper 102 to approach and clamp the new pressing cylinder. After clamping, the rotating assembly 3 is started, causing the second pneumatic gripper 102 to lift upwards so that the new pressing cylinder can be removed from the storage rack. The first lateral movement assembly 4 is then started, causing the rotating assembly 3 to move away from the new pressing cylinder storage rack. The rotating assembly 3 then causes the second pneumatic gripper 102 to rotate downwards to a horizontal position. The first pneumatic gripper 101 is moved closer to the initial pressing cylinder and clamped by the first lateral movement assembly 4. After clamping, the fastening structure between the initial pressing cylinder and the pressing machine is removed or loosened, so that the initial pressing cylinder is disconnected from the pressing machine. The second lateral movement assembly 5 is activated to move the first pneumatic gripper 101 to move the initial pressing cylinder out of the pressing machine. The first lateral movement assembly 4 is activated to move the first pneumatic gripper 101 and the initial pressing cylinder away from the pressing machine. The rotation assembly 3 is activated to rotate the positions of the first pneumatic gripper 101 and the second pneumatic gripper 102. The first lateral movement assembly 4 and the second lateral movement assembly 5 are activated again to insert the new pressing cylinder into the pressing machine and fix it by the fastening structure, thus completing the changeover work.
