Embodiment Construction

[0048] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0049] Such as Figure 1-11 shown.

[0050] A composite production line of PCB hand plug-in processing and patch processing, such as figure 1 As shown, it mainly consists of the following equipment:

[0051] A board machine 1 (such as figure 2 , 3 shown), the loading machine 1 sends the PCB board placed in the upper board channel into the guide rail of the production line in time according to the production rhythm, and is sent into the adjacent screen printing machine 2 under the drive of the conveyor belt in the guide rail; enter The PCB board in the upper board channel of the board loading machine 1 has undergone SMT patch processing and low temperature reflow processing;

[0052] Screen printing machine 2, the screen printing machine 2 is responsible for silk screen printing of low-temperature solder paste on the PCB board that has been sen...

Abstract

The invention discloses a PCB (Printed Circuit Board) production line combining a manual in process processing and paster processing, which is characterized by comprising a board feeding machine (1), a screen printing machine (2), as well as a first board overturning machine (3), an adhesive dispenser (4), a UV curing oven (5), a second board overturning machine (6), SMT (Surface Mounting Technology) equipment (7) and a reflow soldering heating curing oven (8). The first board overturning machine (3) is responsible for overturning a PCB subjected to low-temperature solder past printing of the screen printing machine (2) and then dispensing an adhesive, and after adhesive dispensing, a UV adhesive with a large long-pin device is cured under UV irradiation; after the PCB is overturned by the second board overturning machine, the step of paster production begins; and finally, PCB heating curing is finished in the reflow soldering heating curing oven (8). The invention combines SMT operation and manual in process operation together to realize a double-faced reflow soldering technology, solves the defects of traditional wave-soldering technology, and saves energy since reflow soldering is performed only twice and elements are heated twice.

Description

technical field [0001] The invention relates to an electronic printed circuit board production equipment, in particular to a PCB board production line combining hand-inserting and patching, in particular a composite production line of PCB hand-inserting processing and patching processing. Background technique [0002] As we all know, in the production and processing of electronic products, how to reduce the input of personnel, processes and auxiliary materials to achieve the same quality is the key to reducing production costs and improving production efficiency. BPR is such a new production method. In the past production, there are usually two processing methods: the first is two reflow soldering + one wave soldering, which is to first reflow solder the components on both sides of the PCB, and then complete the SMT production line. The PCB board turnover is transferred to the substrate production line for hand-insertion operation and wave soldering; the other is three-time ...
