Description

Technical Field

[0001] The utility model relates to the field of chip mounters, in particular to a high-speed front and rear arm chip mounter. Background Art

[0002] The existing placement machine usually has a motion assembly of a placement machine head arranged on a workbench, as shown in the prior patent owned by our company with patent number CN202220221860.8, including a placement machine head, an X-axis motion mechanism, a Y-axis motion mechanism, and a Z-axis motion mechanism and an R-axis motion mechanism arranged on the placement machine head; the placement machine head is arranged on the X-axis motion mechanism, and the X-axis motion mechanism is arranged on the Y-axis motion mechanism; the placement machine head moves in the X-axis direction along the X-axis motion mechanism; the placement machine head and the X-axis motion mechanism move in the Y-axis direction along the Y-axis motion mechanism; the Z-axis motion mechanism includes a placement head mechanism and a transmission mechanism; a plurality of placement head mechanisms are arranged on the placement machine head, each of which is controlled by an independent transmission mechanism, and each of which moves up and down along the Z-axis under the control of its corresponding transmission mechanism; and an R-axis motion mechanism is arranged on each of the placement head mechanisms.

[0003] In the operation of a placement machine with this structure, the placement machine head needs to first move above the feeder board seat, pick up the electrical components to be mounted from the feeder board, and then move above the high-speed flying camera mechanism to take pictures of each electrical component on the placement head nozzle in turn to read the component information. The circuit board is transported to the middle of the workbench by the conveyor track, and then the controller issues instructions to sequentially mount the electrical components on each placement head nozzle to the designated positions on the circuit board. Although this structure can realize the automated placement of the placement machine, the disadvantage of this structure is that there is only one set of placement machine heads and a matching machine head motion drive mechanism. The disadvantage of this structure is that the effectiveness efficiency can no longer meet the requirements of existing production, and it is necessary to develop a more efficient and stable high-speed placement equipment.
