Technical Problem

[0004]然而，上述现有技术方案存在一定的局限性，由于泡棉本身质地柔软，剥离件的尖刺部插入泡棉以实现分离的过程中，可能对泡棉造成物理损伤，容易破坏泡棉的结构完整性，破坏泡棉的结构完整性后，泡棉在钣金件运输过程中吸收冲击力性能和缓冲防护性能下降，同时，结构不完整的泡棉也可能在装配时填充钣金件与壳体间隙的紧密性降低

Benefits of technology

1.供料组件将含离型膜与泡棉条的未剥离泡棉稳定转移至分离组件的吸附台，吸附台通过吸附作用对未剥离泡棉整体固定以减少偏移；随后，间距大于单个泡棉条宽度的第一压杆与第二压杆沿竖直方向下移，分别压实离型膜与非目标泡棉，漏出单个目标泡棉条，此时抓取件夹取目标泡棉条时，因离型膜和其他泡棉被压杆固定，目标泡棉可与离型膜自然分离且不受牵连，降低了物理损伤概率，保障了泡棉结构完整性，进而确保泡棉在钣金件运输中的缓冲防护性能及电子设备装配时对间隙的填充紧密性。

Abstract

The application relates to a foam automatic feeding device, belonging to the foam automatic feeding field, which comprises a rack and a feeding mechanism installed on the rack, the feeding mechanism comprises a feeding assembly and a separation assembly, the separation assembly comprises a grabbing piece, a suction table and first and second pressing rods, the first pressing rod is arranged at the end far from the feeding assembly, the second pressing rod is arranged at the end close to the feeding assembly, and the first and second pressing rods are both arranged at the upper end of the suction table and vertically slide, the interval between the first and second pressing rods is greater than one and smaller than two foam strip widths, the feeding assembly transfers the whole foam containing a release film and un-stripped foam to the suction table, the suction table adsorbs and fixes the foam and the release film, the first and second pressing rods move downward to compact the release film and the non-target foam respectively, a single target foam strip is leaked out, the grabbing piece clamps the target foam, the clamping process reduces the probability of causing physical damage of the foam, and the structural integrity of the foam is ensured.
