Description
Technical field
The utility model relates to pcb board correcting technology field, is specifically related to a kind of pcb board apparatus for correcting.
Background technology
When making pcb board (Printed Circuit Board, printed circuit board (PCB)), the PCB finished product is if phenomenon such as plate is curved, plate sticks up, and generally direct Bian pressure bake mode is corrected in test and visual inspection process.See also Fig. 1, traditional apparatus for correcting is arranged in the curved warping anti-stetch machine 100 of plate, and it comprises baking box 101, upper table surface 102 and following table 103, and described upper table surface 102 can slide up and down in baking box 101, and 103 of following tables are fixed in the baking box 101.When using this apparatus for correcting, earlier the bad pcb board of several piece being stacked as one folds, be placed on the following table 103, make upper table surface 102 move down on the pcb board that directly is pressed on the following table 103 again and keep a period of time, the evenness tolerance of upper table surface 102 and following table 103 is ± 2mm (millimeter).The said apparatus complex structure, utilization rate of equipment and installations is low, can only correct the folded pcb board of 2-3 at every turn, and because hot pressing and the step of colding pressing are all carried out, process length consuming time in baking box, and efficient is very low.When using said apparatus to carry out the pcb board rectification, in order to carry out subsequent handling, need repeatedly carry pcb board, easy scratch pcb board produces scrap products after the operation inconvenience.
Summary of the invention
In view of this, the utility model discloses a kind of pcb board apparatus for correcting that improves the pcb board rectification effect, enhances productivity.
The purpose of this utility model is achieved through the following technical solutions: a kind of pcb board apparatus for correcting of realizing above-mentioned pcb board antidote, comprise baking box, be used for stacking the carrier of waiting to correct pcb board, described carrier can be arranged in the baking box with passing in and out, and described carrier is provided with the pressure-applying unit that can exert pressure simultaneously to whole pile of pcb board simultaneously; Also be provided with heat-transferring assembly on the described carrier.
Because described carrier can take out outside the baking box, and the operation that stacks pcb board is carried out more easily, more can reduce the carrying of pcb board, reduces it by the probability of scratch; In addition, when carrying out described cold pressing process, pcb board directly can be taken out together with carrier and carry out, baking box then can continue to come into operation.
Described heat-transferring assembly comprises the heat transfer steel plate that overlays between each folded pcb board.
The heat transfer steel plate is except making pcb board is heated evenly, and its even curface also has the effect that strengthens rectification effect.
Further, described heat transfer surface of steel plate is coated with aluminium matter heat-conducting layer.
In order further to overcome the uneven problem of being heated inside and outside the pcb board that stacks in a pile, the utility model spy is coated with the good thermal conductivity aluminium of tool matter heat-conducting layer at the heat transfer surface of steel plate.
Described aluminium matter heat-conducting layer is 1:20-1:50 with the ratio of the thickness of heat transfer steel plate.
Aluminum material hardness is lower, if the too high gross distortion that then takes place easily of aluminium matter heat-conducting layer thickness.Use the heat transfer steel plate of aluminium matter heat-conducting layer distortion to handle pcb board, not only the plate that can not correct pcb board stick up, problem increased the weight of and cause whole blackboard newspaper useless.Aluminium matter heat-conducting layer thickness is low then to be not enough to the heat transfer effect that provides enough.The utility model designer proposes the ratio of aluminium matter heat-conducting layer and the thickness of heat transfer steel plate is limited to 1:20-1:50 after long term test demonstration, can guarantee that heat-transfer effect has enough hardness again, and its heat transfer efficiency is than clean steel plate hight more than 65%.
Described pressing mechanism comprises that one is positioned over the compression steel plate at whole pile of pcb board top.
Directly compression steel plate is placed on the whole pile of pcb board top that stacks, carrier is sent in the baking oven toasted again, by the weight of compression steel plate self pcb board is exerted pressure.Owing to need not to move up and down during compression steel plate work, improved the utilance of baking box; The heat transfer steel plate of surfacing also has the effect that strengthens rectification effect.
Described carrier bottom tool wheel; Described baking box bottom is provided with the guide rail of carrier turnover.
The present invention has following beneficial effect with respect to prior art:
1. will to count that folded pcb board to be corrected stacks be to exert pressure in whole pile of top after one whole pile to the utility model, thereby correct this pile pcb board simultaneously, improved production efficiency, adopt pcb board antidote disclosed in the utility model and device to correct pcb board, the product of one times of area of each comparable conventional method multiprocessing.
2. the pcb board apparatus for correcting that provides of the utility model has reduced the carrying number of times of pcb board in the processing procedure, simplifies working process and reduces process time, more than 50%, can also avoid being scrapped by scratch in the pcb board handling process simultaneously when economizing on than traditional processing mode.
3. the heat transfer surface of steel plate of pcb board apparatus for correcting provided by the utility model is provided with aluminium matter heat-conducting layer, and the thickness ratio of heat transfer steel plate and aluminium matter heat-conducting layer is optimized, and satisfies the requirement of heat transfer efficiency and hardness simultaneously.Its heat transfer efficiency of heat transfer steel plate that is provided with aluminium matter heat-conducting layer more than 65, has guaranteed that the rectification effect of pcb board is as for more being conducive to energy savings than the ordinary steel plate hight.
4. the pcb board apparatus for correcting that provides of the utility model has good pcb board rectification effect, and corrected rate reaches more than 99%, corrects mode apparently higher than tradition.
