For the shape-milling device, the base plate is fixed on the milling machine board, the four corners of the circuit board are fixed on the base plate, and the middle part of the circuit board is fixed through the adhesive tape and the cover board, so that the shape-milling treatment is realized on the circuit board. Compared with the prior art, the shape-milling device disclosed by the utility model solves the problems that positioning holes are not available in some PCBs (printed circuit boards), so that pins can not be used for positioning, consequently, the production efficiency for forming a routing is low, the forming size of a product can not be guaranteed accurately, and danger exists in operation; the shape-milling device reduces the production cost, and improves the production efficiency; the fixing inside the circuit board is realized by the adhesive tape; and after the shape milling of the circuit board, the adhesive tape can be torn down, and glue residue cannot leave on the circuit board.
Description
Technical field
The utility model belongs to PCB manufacturing technology field, and what be specifically related to is that a kind of wiring board that does not have pin mills appearance device, is used for not milling sharp processing to there being pin in the wiring board plate.
Background technology
Mill profile for wiring board, at present the existing way of industry is: assigned address in circuit board technique limit and the plate is bored locating hole, break pin at each locating hole when milling profile and wiring board is fixed on mills on the machine backing plate, mill profile by milling the plate formula then.
This to assigned address boring in the plate of wiring board; And drill hole fixedly is milled the mode that profile is operated through pin; Solved the traditional circuit plate when milling profile; What produced can't locate the problem that causes the wiring board finished size to guarantee because of wiring board, has reduced the scrappage of product, has improved the quality of wiring board.But this utilization pin is fixed the mode that could mill profile to wiring board to wiring board inside, and it need be provided with locating hole in circuit board technique limit and plate.Yet there is part plank internal customer not allow to be provided with locating hole; Thereby can't use pin to position when causing moulding gong plate; Present stage, most wiring board enterprise adopted the direct hand of operator by on plank; Apply pressure by hand plank is carried out by force fixing, moulding gong plate then, this kind method exists that the wiring board finished size can't accurately be guaranteed, have very big danger and the low problem of moulding production efficiency in the operating process.
The utility model content
For this reason, the purpose of the utility model is to provide a kind of wiring board that does not have pin to mill appearance device, is used for that wiring board is not had pin and mills sharp processing, to reduce production costs, enhances productivity.
For realizing above-mentioned purpose, the utility model mainly adopts following technical scheme:
A kind of wiring board that does not have pin mills appearance device; Comprising backing plate (1), wiring board (2), cover plate (4) with mill board face (6); (1) four edge of said backing plate is provided with locating hole (5); (1) four corner of backing plate is passed above-mentioned locating hole (5) through pin and is fixed on and mills on the board face (6), and (2) four corners of said wiring board are fixed on the backing plate (1) through pin, middlely is adhesively fixed on the backing plate (1) through adhesive tape (3).
Wherein said wiring board (2) is pressed abd fixed on the backing plate (1) through cover plate (4), and adhesive tape (3) is positioned between wiring board (2) and the cover plate (4), and adhesive tape (3) two ends are bonded on the backing plate (1).
The utility model is fixed on wiring board four corners on the backing plate through shim is being milled on the board face, and the centre is then fixed through adhesive tape and cover plate, with realization the profile of milling of wiring board is handled.Compared with prior art, the utility model has solved the interior no locating hole of part pcb board can't use the pin location, causes the problem that moulding gong plate production efficiency is low, the shaped article size can't accurately be guaranteed and operate dangerous property; Thereby reduced production cost; Improved production efficiency, and realized that through adhesive tape the plate of wiring board is interior fixing, after wiring board mills profile; Can adhesive tape be torn, can residual in the circuit board glue stain.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Identifier declaration among the figure: backing plate 1, wiring board 2, adhesive tape 3, cover plate 4, locating hole 5, mill board face 6.
The specific embodiment
For setting forth the thought and the purpose of the utility model, will combine accompanying drawing and specific embodiment that the utility model is done further explanation below.
See also shown in Figure 1ly, Fig. 1 is the structural representation of the utility model.The utility model provides a kind of wiring board that does not have pin and mills appearance device; Be used for when wiring board being milled the profile processing; Because of no locating hole can't pin the location adopts artificial fixedly cause moulding gong plate production efficiency lowly, the shaped article size can't accurately be guaranteed and operated the problem of dangerous property; Thereby reduced production process, reduced production cost, improved production efficiency.
Wherein this device comprises backing plate 1, wiring board 2, cover plate 4 and mills board face 6; Four edges of said backing plate 1 are provided with locating hole 5; Four corners of backing plate 1 are passed above-mentioned locating hole 5 through pin and are fixedly mounted on and mill on the board face 6; It mainly acts on is to be convenient to wiring board 2 milled, and don't as for hurting the lathe that mills machine.
Four corners of wiring board 2 also are provided with locating hole; Be fixed on the backing plate 1 through pin, the centre position of wiring board 2 then is adhesively fixed on the backing plate 1 through many adhesive tapes 3, and adhesive tape 3 two ends correspondences are bonded on the backing plate 1; Through fixing of two ends, with closely being fixed on the backing plate 1 in the middle of the wiring board 2.
On wiring board 2, also be provided with a cover plate 4, this cover plate 4 is pressed on the wiring board 2, be used for it is pressed abd fixed on backing plate 1, and above-mentioned adhesive tape 3 is between wiring board 2 and cover plate 4, and adhesive tape 3 two ends are bonded on the backing plate 1.
The adhesive tape that the utility model adopts is red adhesive tape, and all bonding red adhesive tape directions are consistent, and when the red adhesive tape here tore after milling the profile end, no glue stain was in the circuit board residual.
The operation principle of the utility model is: at first cleaning is milled machine lathe table top, with backing plate four angular bit locating holes, is fixed on shop bolt and mills on the machine lathe, with circuit board technique limit four angular bit locating holes, is fixed on the backing plate with shop bolt again; Once mill the profile formula according to what mixed up then, the same direction of wiring board (radially or broadwise) is milled moulding; In the circuit board with once mill profile and mill on the vertical direction of plate direction and to paste red adhesive tape, pasted on the red adhesive tape bonnet and the measure-alike cover plate of wiring board, fix with red adhesive tape at the Qi Sijiao place; Mill the profile formula according to secondary, wiring board other direction (broadwise or radially) is milled moulding, accomplish the last moulding of wiring board, mill board parameter and once to mill formal parameter identical; Mill after profile finishes, tear red adhesive tape, take off wiring board.
More than be that a kind of wiring board that does not have pin that the utility model is provided mills appearance device and carried out detailed introduction; Used concrete example among this paper the structural principle and the embodiment of the utility model are set forth, above embodiment just is used to help to understand the method and the core concept thereof of the utility model; Simultaneously, for one of ordinary skill in the art, according to the thought 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.
