Abstract
The utility model discloses a window former for a PCB negative plate, and relates to a negative plate cutting device for counterpoint exposure of PCBs. A negative plate requiring window formation is punched in a punching manner, and the operation method is that the negative plate requiring window formation is horizontally placed on a bottom platform (10) according to the size of the window former for the PCB negative plate and aligned with the part under a rectangular groove knife, and the negative plate is positioned; then a punching handle (1) is pressed down, a cylinder (7) is positioned on the punching handle (1), the rectangular groove knife connected below the cylinder (7) is driven to be downwardly pressed on the negative plate, and the knife edge of the rectangular groove knife (9) cuts a rectangular window on the negative plate; and finally, the punching handle automatically bounds to the original position under the action of a spring (4) to complete window formation on the negative plate. The window former has a uniform punching force, is simple and convenient to operate, and not only guarantees the quality of the formed window but also greatly improves the window formation efficiency, and the window formed by the window former is burr-free.
Description
Technical field:
The utility model relates to a kind of PCB manufacturing technology field, refers more particularly to a kind of egative film Scissoring device that is used for to PCB contraposition exposure.
Background technology:
At present, need use a kind of Diazo Master Film in the PCB figure transfer process and carry out the contraposition exposure, in the process of contraposition; Four jiaos of egative film need cut out a strip circle, stick the single face gummed paper then, and egative film and plate can be pasted on the pcb board according to dimension precision requirement in the contraposition process; Play fixed operation, on egative film, determine a strip frame, in the industry cycle be called egative film and window; Method commonly used is to comply with on the egative film limit with scissors or blade to require size to determine, and this mode is determined the big or small disunity of the frame that comes, and uses scissors or blade operation to be prone to wiping flower egative film; And edge is prone to deposit burr, is prone to cause PCB bad in the production use.
The egative film of using in the PCB contraposition process by hand is to adopt 0.1mm or the coating of 0.175mm sheet base to form; Evenly scribble the molecular layer medicine film of the faint yellow photographic chemistry article of skim on the sheet basal plane; Main component in the molecule is organic aromatic azo-compound, so term abbreviates Diazo Master Film as.
When the cutting of adopting scissors or blade to carry out egative film in the known production process is windowed, be prone to collide medicine film place, wipe the flower pesticide film; Cause the medicine film to come off, and cutting when operation time, need the artificial egative film of taking on the other hand; Carry out cutting with blade on the other hand, egative film can't be fixed, and the size of determining differs; And dynamics is uneven, is prone to cause the limit of being cut out to produce burr.
The PCB egative film window opener that the utility model provides utilizes the mode of punching press, and the egative film frame of the required size of windowing is gone out; When windowing, egative film can lie against the window opener table top, the egative film window fixed size that stamps out; And the punching press dynamics is even, and the egative film window does not have burr, and is easy and simple to handle; Not only can guarantee the quality of windowing, and can improve personnel's operating efficiency.
Summary of the invention:
For realizing above-mentioned purpose, the utility model mainly adopts following technical scheme:
Described PCB egative film window opener comprises: punching press handle, length are 250mm, and diameter is 15mm, and an end is connecting prismatoid.
Described PCB egative film window opener comprises: 2 traveling nuts, traveling nut is connecting prismatoid and fixed station.
There is a cross bar at the middle part of described fixed station, and a circular port is established in the centre of cross bar.
Described PCB egative film window opener comprises: 1 spring, cylinder and rectangular recess cutter.Cylinder is enclosed within the circular port of establishing in the middle of the fixed station cross bar, and spring housing is in cylindrical the first half, and cylinder the latter half and rectangular recess cutter link together.
Described rectangular recess cutter is made up of the blade that two length blade that is 45mm and two length are 5mm.
Described PCB egative film window opener comprises: the fixed support platform, and long is 15mm, wide is 10mm.
Described PCB egative film window opener comprises: bottom platform, and long is 28mm, wide is 18mm.
Compared with prior art, the PCB egative film window opener that the utility model provides adopts the mode of punching press, and the egative film frame of the required size of windowing is stamped out; When windowing, egative film can lie against the window opener table top, the egative film window fixed size of going out, and the punching press dynamics is even; The egative film window does not have burr, and is easy and simple to handle, not only can guarantee the quality of windowing and the improved efficiency of windowing; Every egative film needs 60 seconds before using window opener, uses window opener only to need 10 seconds, and improved efficiency 80% is increased work efficiency greatly.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model texture edge figure.
Identifier declaration among the figure: 1 punching press handle, 2 prismatoids, 3 traveling nuts, 4 springs, 5 cross bars, 6 fixed stations, 7 cylinders, 8 fixed support platforms, 9 rectangular recess cuttves, 10 bottom platform.
The specific embodiment:
The conception of the core of the utility model is: adopt the mode of punching press, the egative film frame of the required size of windowing is stamped out, when windowing, egative film can lie against the window opener table top, the egative film window fixed size of going out, and the punching press dynamics is even, and the egative film window does not have burr, and is easy and simple to handle.
For setting forth novelty, practicality, ideamonger and the purpose of the utility model, will combine accompanying drawing and specific embodiment that the utility model is done further explanation below.
As shown in Figure 1, the PCB egative film window opener that the utility model provides comprises: 1 punching press handle, 2 prismatoids, 3 traveling nuts, 4 springs, 5 cross bars, 6 fixed stations, 7 cylinders, 8 fixed support platforms, 9 rectangular recess cuttves, 10 bottom platform.Concrete operations situation following steps:
The egative film that need are windowed lies in a horizontal plane on 10 bottom platform according to the size of PCB egative film window opener, aim at 9 rectangular recess cuttves under, carry out the egative film location; Depress 1 punching press handle then, 7 cylinders are at 1 punching press handle, and the 9 rectangular recess cuttves that drive is connected in below 7 cylinders are pressed on the egative film downwards; The blade of 9 rectangular recess cuttves cuts out a rectangular window to egative film; Last 1 punching press handle rebounds automatically and returns original position under the effect of 4 springs, accomplishes egative film and windows; Take off egative film, carry out windowing of next egative film.
More than the PCB egative film window opener that the utility model provided has been carried out detailed introduction; Used concrete example among this paper the principle and the embodiment of the utility model are set forth, the explanation of above embodiment just is used to help to understand the method for using and the core conception thereof of the utility model; Simultaneously, for one of ordinary skill in the art, according to the conception of the utility model, the part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
