The invention relates to the field of flexible circuit board bending, in particular to a clamp for bending multiple positions of a flexible circuit board, a clamp opening and closing system and an opening and closing method. The clamp comprises a clamp bottom plate, a positioning column, a first positioning sliding block, a second positioning sliding block and an overturning clamping plate. A first supporting part, a second supporting part, a third supporting part and a fourth supporting part are arranged on the clamp bottom plate. The first supporting part, the second supporting part and the third supporting part are arranged on the front side of the clamp bottom plate side by side. The fourth supporting part is arranged on the left side of the clamp bottom plate. A first hollow part is arranged on the right side of the first supporting part. A second hollow part is arranged between the first supporting part and the second supporting part. A third hollow part is arranged between the second supporting part and the third supporting part. A first concave part is formed by the left side of the third supporting part and the front side of the fourth supporting part. A second concave part is arranged on the rear side of the fourth supporting part. According to the clamp, a space is reserved for subsequent bending, so that the bending operation of a circuit board by a subsequent device is facilitated.
Description
technical field [0001] The invention relates to the field of bending and forming of flexible circuit boards, in particular to a fixture for multiple bending of flexible circuit boards, a fixture opening and closing system and an opening and closing method. Background technique [0002] At present, most of the bending of the flexible circuit board (referred to as FPC) is to be bent by upper and lower knife clamping. [0003] For example, the Chinese invention patent (publication number: CN110757777A, publication date: 20200207) discloses an automatic bending machine for flexible circuit boards, including a workbench, an upper knife pressing mechanism and a rotary bending mechanism. The upper knife pressing mechanism includes upper knife and The first air cylinder, the upper knife is driven and connected with the first air cylinder; the rotary bending mechanism includes a second air cylinder, a transmission assembly and a rotary bending knife. Knife drive connection; when wor...
