Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flexible printed circuit boards, in particular to a flexible circuit board bending device. BACKGROUND

[0002] In the process of assembling the electric control unit of the automobile electric steering machine, the assembly of the double-layer flexible circuit board is involved. After the first layer of circuit board is assembled on the motor, the second layer of circuit board needs to be assembled to the appropriate position through the bending of the flexible board and then fastened by bolts. The existing double-layer circuit board needs to be bent at the corner position, so that the circuit board can be reliably installed at the corner position. The existing assembly line adopts manual bending of the flexible circuit board, and the assembly process cannot avoid the fact that the flexible circuit board is not subjected to tensile stress and compressive stress, and the manual efficiency is low, which cannot meet the requirements of the assembly line rhythm.

[0003] The prior art, such as the patent document with the Chinese patent application number 202322540682.2 and the publication date of May 28, 2024, discloses a flexible circuit board automatic bending device, which comprises a device base, a workpiece tray, a moving track, a support base grabbing mechanism, a clamping and overturning mechanism, and a tightening mechanism. The moving track is fixed on the device base, and the workpiece tray 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 tray comprises a tray, a fixed base, and a circuit board support base. The clamping and overturning mechanism is arranged on the two side surfaces of the moving track. The clamping and overturning mechanism clamps the circuit board support base at the bending station and moves along the set bending track to bend the flexible circuit board. The tightening mechanism is movably fixed on the upper part of the clamping and overturning mechanism and is used for tightening the bolts to fix the second layer of circuit board on the workpiece. The above document uses a relatively compact mechanical design to meet the requirements of the new test process, and reserves a certain flexibility to adapt to the requirements of different product characteristics.

[0004] However, in the existing flexible circuit board, if multiple circuit boards are to be installed in the same device, a connector is usually used to connect the terminals of two or more circuit boards, which facilitates subsequent installation of the circuit boards and makes installation more convenient. However, the installation of the connector cannot ensure that the connector and the connecting terminal are reliably positioned when connected. Multiple circuit boards cannot be bent simultaneously, but have to be bent separately. However, after separate bending, the bending positions of the two or more circuit boards may not be consistent, which may cause inaccurate installation. SUMMARY

[0005] The present application provides a flexible circuit board bending device, which enables the circuit board to be stably installed on the connector and ensures that the bending positions of the two circuit boards are consistent.

[0006] To achieve the above object, the technical scheme of the present application is: a flexible circuit board bending equipment, comprising a rack, a first workbench for placing a first circuit board is arranged on the rack, a turnover device is arranged on one side of the rack of the first workbench, a second workbench for placing a second circuit board is arranged on the turnover device, the turnover device drives the second workbench to turn over to the first workbench so that the first circuit board and the second circuit board correspond; a thimble device is arranged on the other side of the rack of the first workbench, the thimble device extends into the first circuit board and the second circuit board and abuts against the connecting terminal of the first circuit board and the second circuit board, and a gap is formed between the first circuit board and the second circuit board through the thimble device; an assembling mechanism is arranged on the front end of the rack of the first workbench, the assembling mechanism installs a connector on the connecting terminal of the first circuit board and the second circuit board; a placing table for placing the first circuit board is arranged on the front end of the first workbench, the connecting terminal of the first circuit board extends out of the placing table, a bending interval is arranged between the placing table and the first workbench, a bending device is arranged below the bending interval, and the bending device bends the first circuit board and the second circuit board on the first workbench through the bending interval.

When the installation of the connector is completed, the ejector pin device and the flipping device are reset, and the first circuit board and the second circuit board are bent by the bending device. Since the first circuit board and the second circuit board have been fixed to the connector, the bending positions of the first circuit board and the second circuit board are consistent when they are bent, thereby facilitating the subsequent installation of the circuit boards. The first circuit board and the second circuit board are aligned when the connector is connected, so that after the two circuit boards are connected by the connector, only the bending device needs to be started to bend, and the two circuit boards do not need to be moved to the bending device.
