Description

Technical Field

[0001] The utility model relates to an auxiliary device for an automatic brake pad production line, in particular to a flexible steel back storage. Background Art

[0002] The patent of "a steel back storage device with precise steel back positioning" (publication number: CN211542537U) publicly disclosed on September 22, 2020 in China, disclosed the following technical details: a frame, a positioning plate, a positioning mechanism support column, a positioning mechanism adjustment screw, a positioning platform, a positioning adjustment plate, and a positioning pin. Among them, the positioning mechanism support column is installed on the top plate of the frame; the positioning platform is installed at the upper end of the positioning mechanism support column; the positioning adjustment plate is provided with a threaded hole and is installed on the end face of the positioning platform; the positioning mechanism adjustment screw is installed in the threaded hole of the positioning adjustment plate; the positioning plate is provided with a pin hole and is installed on the positioning platform; the positioning pin is installed in the pin hole of the positioning plate. However, this device needs to be additionally equipped with a pick-and-place hand to place the steel back from the steel back bin on the positioning plate, and then use the pick-and-place hand to place the steel back on the positioning plate into the brake pad mold. As a result, the placement of the steel back and the placement into the mold cannot be carried out simultaneously, and can only be placed into the mold after the placement is completed, which greatly reduces the production efficiency of the brake pads. Moreover, the placement position of the steel back is restricted by the positioning pin and cannot be adjusted as needed. For example, the steel backs are placed in a 2*2 pattern as shown in the patent drawings. When the production line is adjusted to increase or decrease the molds or different specifications of steel backs, a new steel back storage device needs to be purchased. Summary of the Invention
