Abstract
The utility model discloses an exposure device for a PCB plate. The exposure device comprises an exposure machine, and a workbench surface arranged on the exposure machine, wherein a double-layer film is arranged on the workbench surface; and the double-layer film is fixed on the workbench surface by location nails. Via the design aforementioned, location speed and accuracy for the films can be greatly increased, and then exposure efficiency for the PCB plate can be increased.
Description
Technical field
The utility model belongs to the circuit board fabrication field, particularly be a kind of pcb board exposure device while manufacturing circuit board.
Background technology
Along with scientific and technological development and the raising of technology, oneself becomes trend and the direction of development the portable belt electronic product of ultra-thin and ultra-light.Correspondingly, that uses the circuit board volume of these electronic products also to become is more and more less, requires positioning precision also more and more higher.Therefore in the course of processing of pcb board, the accurate processing of product and the accurate exposure of pcb board seem particularly important.
Often need double-sided exposure in the pcb board manufacture process at present, its general operation principle is: the film on folded on the two sides of PCB plate, then by location weld-ring and pcb board location hole on film limit visual accurate after, utilize gummed paper to pasting, putting plate into exposure machine is afterwards exposed, tear after the exposure film on plate two sides, complete exposure.Adopt afterwards and use the same method to operate second pcb board, not only speed is slow for this mode of operation, accuracy is low but also the lost labor.
The utility model content
The purpose of this utility model is to overcome in prior art the exposure pcb board need to paste the defect of tearing the film repeatedly, provides a kind of simple in structure and film to locate fast pcb board exposure device.
For achieving the above object, the technical solution of the utility model has been to provide a kind of pcb board exposure device, comprise exposure machine and be located at the work top on exposure machine, described work top is provided with the double-deck film, and the double-deck film is fixed on described work top by locating pin.
As preferably, the described double-deck film comprises the upper and lower two-layer film, on the upper and lower film, is printed on respectively the pcb board circuit diagram cooperatively interacted, the edge bonding connection of the upper and lower film, and junction, upper and lower film edge is provided with opening.
As preferably, described locating pin is 4, is symmetricly set on the surrounding of the double-deck film.
Advantage of the present utility model and beneficial effect are: can greatly improve locating speed and the accuracy of the film by above design, improve the exposure efficiency of pcb board.
The accompanying drawing explanation
Fig. 1 is perspective view of the present utility model;
The structural representation that Fig. 2 is the double-deck film;
In figure: 1, exposure machine; 2, work top; 3, the double-deck film; 4, circuit diagram; 5, locating pin; 6, the upper film; 7, the lower film; 8, opening.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model more clearly is described, and can not limit protection range of the present utility model with this.
As shown in Fig. 1 Fig. 2, a kind of pcb board exposure device comprises exposure machine 1 and is located at the work top 2 on exposure machine 1 that described work top 2 is provided with the double-deck film 3, and the double-deck film 3 is fixed on described work top 2 by locating pin 5.
The described double-deck film 3 comprises the upper and lower two- layer film 6 and 7, on the upper and lower film 6 and 7, is printed on respectively the pcb board circuit diagram 4 cooperatively interacted, the upper and lower film 6 and 7 edge bonding connection, and the upper and lower film 6 and 7 junctions, edge are provided with opening 8.
Described locating pin 5 is 4, is symmetricly set on the surrounding of the double-deck film 3.
In practical operation, pcb board is inserted from the opening 8 of the double-deck film 3, because the circuit diagram 4 on the upper strata film 6 and lower floor's film 7 shifts to an earlier date printed, and upper and lower circuit diagram 4 outward flanges coincide, after pcb board inserts the double-deck film 3, the upper and lower surface position of pcb board is all corresponding with circuit diagram 4, at this moment opens 1 pair of pcb board of exposure machine and carries out exposing operation and get final product.Such design has improved the efficiency of exposure greatly, has saved the loaded down with trivial details process of pad pasting repeatedly.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
Claims (3)
