Abstract
A control circuit of a printed circuit board (PCB) work station comprises a temperature control part, a pressure control part, a lifting device, a control button and an alarm display, elements to be removed are heated, the temperature of elements is controlled, elements are not damaged and removed though the setting of the highest temperature and a heating heater, after old elements are removed, a PCB is cleaned, the preparing is for the welding of new elements, welding materials are removed, new elements are placed, welding is conducted, the repairing process of the board is completed, the use rate of the PCB is improved and the waste of resources is reduced.
Description
Technical field
The invention belongs to the industrial control technology apparatus field, be specifically related to a kind of control circuit of PCB workstation.
Background technology
Most of surface-assembled manufacturings and processing procedure slip-stick artist's primary goal is to improve the qualification rate of initial survey assembly, and therefore, the slip-stick artist concentrates on main energy in initial manufacturing certainly, reprocesses processing procedure and seldom take into account.yet in fact, be subjected to the PCB(printed circuit board (PCB)), components and parts, scaling powder, solder(ing) paste, the impact of the factors such as mounting equipment, even best manufacturing equipment, the automaticity of assembling is high again, also be difficult to avoid occurring defective product, extensive application along with High density of PCB and the novel encapsulated integrated circuit of costliness, make the cost of PCB assembling increase to some extent, if do not calculate because the problem of individual metablocks device is sacrificed the monoblock plank, and more and more stricter He meticulous detection means makes manufacturer more easily find these defectives at present, therefore the pcb board that need to reprocess is also in continuous increase.
Summary of the invention
To achieve these goals, the apparatus that pin of the present invention provides a kind of PCB to reprocess can be reprocessed by this equipment automatically to the pcb board that needs are reprocessed, and improves the utilization factor of pcb board, reduces the waste of resource.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is:
A kind of control circuit of PCB workstation comprises: temprature control unit, pressure control section, lifting gear, control knob and alarm indication;
Described temprature control unit is by adopting the scolder of infrared heating technique melting member solder joint, by being set, maximum temperature and timer form closed-loop control system, be that being heated of element is unlikely to too high and damages, adopt closed-loop control, realize the accurate control to temperature;
Whether described pressure control section is to detect by dismounting and the welding of pressure transducer to element, prevent from can element being posted by pressure detection because overvoltage causes component wear;
Described lifting gear is the mobile device with dismounting and the installation of element, by controlling the movement of this device, and the accurate position of setting element.
The basic step of reprocessing is: dismantle old element, remove amount of residual solder and clean this zone, mount new element, soldered elements, the control procedure of workstation is: to needs remove element heat, and its temperature is controlled, can guarantee not damage element and it is removed by maximum temperature being set and heating timer, after old element removes, need to clean pcb board, for the welding of new element is prepared, scolder on clear board, then place new element, weld, complete the rework process of plank.
Description of drawings
Accompanying drawing is the control circuit figure of PCB reclamation work platform of the present invention.
Embodiment
As shown be PCB reclamation work of the present invention station and get control circuit, the reclamation work station is by using the light splitting vision system with the PCB of PCB pad and BGA(ball grid array structure) solder joint is imaged on display simultaneously, regulate the position of PCB, PCB pad and BGA solder joint are overlapped.the reclamation work station is to disassemble from PCB device is undamaged, again new device mounted up exactly and carry out high-quality welding, during the dismounting element, at first make the solder joint solder fusing of element by infrared heating, maximum temperature and the heating timer of heating are set, detect the higher limit that whether reaches heating by temperature sensor, and to controlling heat time heating time, pcb board can not damaged because of continuous heating, use lifting gear that element is taken out from PCB, the automatic lifting mechanism that carries out the automated location lifting when element is pulled down removes element, after element removes, need to clean pcb board, namely remove scolder residual on plank, place new element, detect by pressure transducer and whether element is placed with, weld at last, after completing, system sends sound and light alarm, prompting is reprocessed and is completed.
Claims (2)
1. the control circuit of a PCB workstation comprises: temprature control unit, pressure control section, lifting gear, control knob and alarm indication, it is characterized in that,
