Automatic pre-stacking equipment for browned PCB

Abstract

The invention discloses an automatic pre-stacking device for a browned PCB, and belongs to the technical field of PCB manufacturing. According to the technical key points, the automatic pre-stacking device comprises a machine box, an operation opening is formed in one side surface of the machine box in the length direction, a pre-stacking station is arranged in the machine box corresponding to the operation opening, and a pre-stacking table is arranged in the pre-stacking station; a PP sheet stacking and storing station and a browned board stacking and storing station are arranged on the two sides of the pre-stacking station; a PP sheet stacking table is arranged in the PP sheet stacking and storing station, and a browned board stacking table is arranged in the browned board stacking and storing station; a horizontal driving mechanism is arranged in the machine box, and lifting type vacuum adsorption units matched with all the stations are connected to the horizontal driving mechanism; and the lifting type vacuum adsorption unit sequentially adsorbs and conveys PP sheets on the PP sheet stacking table and browned boards on the browned board stacking table to the pre-stacking table for stacking. The invention aims to provide the automatic pre-stacking equipment for the browned PCB, which is compact in structure, high in working efficiency and low in pre-stacking error rate; and the equipment is used for automatically pre-stacking browned boards.

Description

technical field [0001] The present invention relates to a kind of PCB production equipment, more specifically, relates to a kind of automatic pre-stacking equipment of PCB browning board. Background technique [0002] In the PCB manufacturing process, it is necessary to pre-stack the browned board and the PP sheet according to the needs, and then press them to form a PCB semi-finished product after typesetting. In the prior art, manual pre-stacking is often used. This operation method not only has low work efficiency and high labor intensity, but also is prone to over- or under-positioning of PP sheets due to operational errors or negligence. And so on, resulting in the scrapping of semi-finished products after subsequent processing. In the probability of abnormal situations, the PP sheets are mainly put in more, because PP sheets are thinner and easier to stick. If workers do not pay attention when taking the sheets, it is very easy to take out multiple sheets at a time. ...

In the prior art, manual pre-stacking is often used. This operation method not only has low work efficiency and high labor intensity, but also is prone to over- or under-positioning of PP sheets due to operational errors or negligence. And so on, resulting in the scrapping of semi-finished products after subsequent processing

In the probability of abnormal situations, the PP sheets are mainly put in more, because PP sheets are thinner and easier to stick. If workers do not pay attention when taking the sheets, it is very easy to take out more than one sheet at a time.
