Description

Technical Field

[0001] The invention relates to the technical field of flexible printed circuit boards, and in particular to a flexible circuit board bending device. Background Art

[0002] The assembly process of the electric steering control unit of the automobile involves the assembly of a double-layer flexible circuit board. After the first layer of the circuit board is installed on the motor, the second layer of the circuit board needs to be assembled to the appropriate position by bending the flexible board and then fastened by bolts. The existing double-layer circuit board needs to be turned for the corner position so that the circuit board can be reliably installed at the corner position. The existing assembly line uses manual bending of the flexible circuit board. The assembly process cannot avoid the flexible circuit board from being subjected to tensile stress and compressive stress, and the low labor efficiency cannot meet the line beat requirements.

[0003] Prior art, such as the patent document with Chinese patent application number 202322540682.2 and announcement date 2024.05.28, discloses an automatic bending device for a flexible circuit board, including a device base, a workpiece pallet, a moving track, a support base grabbing mechanism, a clamping and flipping mechanism and a tightening mechanism; the moving track is fixed on the device base, and the workpiece pallet is movably fixed on the moving track; the support base grabbing mechanism is arranged on the upper part of the moving track for grabbing the circuit board support base; the workpiece pallet includes a pallet, a fixed base and a circuit board support base; the clamping and flipping mechanism is arranged on both sides of the moving track, and the clamping and flipping mechanism at the bending station clamps the circuit board support base to move along the set bending trajectory to bend the flexible circuit board; the tightening mechanism can be lifted and fixed on the upper part of the clamping and flipping mechanism, and is used to tighten the bolts to fix the second layer of the circuit board on the workpiece. The above documents use a relatively compact mechanical design to meet the requirements of the new test process, and reserve a certain degree of flexibility to adapt to the requirements of different product characteristics.

[0004] However, in the existing flexible circuit boards, if multiple circuit boards are to be installed in the same device, connectors are usually used to connect the terminals of two or more circuit boards. This makes it easier to avoid confusion during the subsequent installation of the circuit boards and makes the installation more convenient. However, the installation of the connector cannot ensure that the connector can be reliably limited when connected to the connecting terminals. Multiple circuit boards cannot be bent at the same time, but the bending operations are performed separately for the multiple circuit boards. However, after the separately bent circuit boards are installed, bending more than two circuit boards may result in inconsistent bending positions, thereby causing inaccurate installation.

The bending limit base plate 64 is driven by the bending limit cylinder 61 to move to a position above the first workbench 11 corresponding to the first circuit board and the second circuit board, and the bending lifting cylinder 66 drives the bending limit plate 67 to move downward and limit the first circuit board and the second circuit board, thereby ensuring that when the first circuit board and the second circuit board are bent, the positions of the first circuit board and the second circuit board are not easily changed, thereby ensuring the stability of the bending.

[0047] The working principle of the present invention is as follows: by setting a first workbench 11 for placing a first circuit board and a second workbench 12 for placing a second circuit board, when installing the circuit boards, the first circuit board is first placed on the first workbench 11, and the second circuit board is placed on the second workbench 12, thereby the second circuit board is flipped by the flipping device 2 so that the second circuit board can be flipped to the top of the first circuit board, so as to facilitate the connector 03 to install the connecting terminals of the first circuit board and the second circuit board, and at the same time, by setting the ejector device 3, by extending the ejector device 3 from one side of the first circuit board and the second circuit board to between the first circuit board and the second circuit board, so that there is a certain gap between the first circuit board and the second circuit board, The connector 03 is sleeved onto the first circuit board and the second circuit board, and the connecting terminals on the first circuit board and the second circuit board are respectively connected to the connectors, and the connecting terminals of the first circuit board and the second circuit board are supported by the ejector device 3, so that when the connector 03 is assembled, the connecting terminals of the first circuit board and the second circuit board will not be pushed by the connector 03, so that the installation of the connector 03 is stable and not easy to be misplaced; when the connector 03 is installed, the ejector device 3 and the flip device 2 are reset, and the first circuit board and the second circuit board can be bent by the bending device 4. Since the first circuit board and the second circuit board have been fixed to the connector 03, the bending positions of the first circuit board and the second circuit board are guaranteed to be consistent during bending, which facilitates the subsequent installation of the circuit boards.
