Abstract

The utility model provides an air guiding groove base plate for routing. The air guiding groove base plate for routing is used for supporting a PCB in the process of routing of the PCB. The air guiding groove base plate for routing is provided with a plurality of air guiding grooves which are interlaced longitudinally and transversely. The air guiding grooves in the air guiding groove base plate for routing are arranged in a rectangular array mode. Corresponding to the PCB, the air guiding grooves which are interlaced longitudinally and transversely form a work area of the air guiding groove base plate for routing. The two sides of each air guiding groove are provided with guiding-out grooves, wherein the guiding-out grooves are communicated with the air guiding groove and extend out of the working area. When routing is conduced on the PCB, the portion, to be routed, of the PCB and the air guiding grooves are aligned in the thickness direction of the air guiding grooves. Dust generated in the process of routing of the PCB is guided out of the PCB through the air guiding grooves and the guiding-out grooves. According to the air guiding groove base plate for routing, the air guiding grooves are formed, an original plane base plate is replaced, the dust generated in the process of routing of the PCB is effectively removed, and when a routing cutter 50 with the diameter smaller than (equal to) 1.2 mm or the aspect ratio larger than 1:2 is used for routing, dust blockage is avoided.

Description

Gong plate wind guide tank backing plate
Technical field
The utility model relates to a kind of backing plate, is specifically related to a kind of gong plate wind guide tank backing plate.
Background technology
In PCB manufacture field, normal used thickness is that 2.2MM, 2.7MM or 3.0MM drilling liner plate support pcb board with protection table top, and the supporting surface of this drilling liner plate is plane.
But, while using plane backing plate to support, when adopting diameter to be less than (equaling) 1.2MM or aspect ratio to be greater than 1:2 gong cutter and to carry out gong plate, there will be large template powder to get lodged in gong groove or be bonded at gong groove sidewall, and cannot remove by washing normally plate, can only or return gong processing by manual repair, reduce production efficiency, improve cost of labor.
Utility model content
Based on this, be necessary for deficiency of the prior art, a kind of gong plate wind guide tank backing plate is provided.
The utility model is achieved in the following ways: a kind of gong plate wind guide tank backing plate, during for pcb board gong plate, support pcb board, on this gong plate wind guide tank backing plate, offer some crisscross air slots, the rectangular arrayed of air slot on described gong plate wind guide tank backing plate, the corresponding pcb board of crisscross air slot forms the working region of gong plate wind guide tank backing plate, each air slot both sides offers and is communicated with this air slot and extends to working region derivation groove in addition, during pcb board gong groove, the part for the treatment of gong groove of pcb board is alignd with air slot thickness direction, the dust that pcb board gong groove produces is extended pcb board with exterior domain by air slot and derivation groove.
Further, the groove width of the air slot of described inner side is 1.0~1.5MM, and the thickness of slab of gong plate wind guide tank backing plate is 2.5~3.5MM.
Further, the material of this gong plate wind guide tank backing plate is epoxy resin board.
In sum, the utility model gong plate wind guide tank backing plate is provided with several air slots, replace original plane backing plate, the dust producing while making pcb board gong groove is effectively removed, and uses diameter to be less than to have no dust when gong cutter 50 that (equaling) 1.2MM or aspect ratio be greater than 1:2 carries out gong plate processing gong groove to stop up.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model gong plate wind guide tank backing plate.
Schematic diagram when Fig. 2 is the use of the wind guide tank of gong plate shown in Fig. 1 backing plate cooperation gong cutter.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, be a kind of gong plate wind guide tank backing plate 10 of the present utility model, the bottom surface of supporting pcb board 50 while carrying out gong plate for pcb board 50 adds the work top in man-hour with protection, make gong cutter 60 on pcb board 30, complete the operation of gong plate.
Described gong plate wind guide tank backing plate 10 platy structure that is square, on gong plate wind guide tank backing plate 10, offer some crisscross air slots 20, the rectangular arrayed of air slot 20 on this gong plate wind guide tank backing plate 10, the corresponding pcb board 50 of crisscross air slot 20 forms the working region 30 of gong plate wind guide tank backing plate 10.Each air slot 20 both sides offers and is communicated with this air slot 20 and extends to working region 30 derivation groove 40 in addition, the groove width of described air slot 20 is 1.0~1.5MM, the thickness of slab of gong plate wind guide tank backing plate 10 is 3.0MM, during gong plate, the part for the treatment of gong groove of pcb board 50 is alignd with air slot 20 thickness directions, the dust that pcb board 30 gong grooves produce is extended pcb board 50 with exterior domain by air slot 20 and derivation groove 40, and the dust in pcb board 50 gong grooves is effectively removed.
The preparation method of the utility model gong plate wind guide tank backing plate is as follows:
1, on the drilling liner plate of 2.5~3.5MM thickness or the epoxy resin board of 2.5~3.5MM thickness, get out Guan Weikong, in this example example, the thickness of slab of described drilling liner plate or epoxy resin board is 3.0MM;
2, according to the designing requirement of product, adopt gong type lathe to process Guan Weikong, make Guan Weikong form the air slot 20 of some arrayed, the groove width of this air slot 20 is 1.0~1.5MM.
In sum, the utility model gong plate wind guide tank backing plate is provided with several air slots 20, replace original plane backing plate, the dust producing while making pcb board 50 gong groove is effectively removed, and uses diameter to be less than to have no dust when gong cutter 50 that (equaling) 1.2MM or aspect ratio be greater than 1:2 carries out gong plate processing gong groove to stop up.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
