Abstract
The utility model discloses a board splitting fixture which comprises a fixture base and a fixture cover plate, wherein a plurality of milling cutter holes are formed in the fixture base; and a plurality of cutting grooves are formed in the fixture cover plate. According to the technical scheme disclosed by the utility model, the board splitting fixture is simple in structure and convenient to use; and the board splitting fixture can be used for fixing a PCBA (Printed Circuit Board Assembly) board in the advance direction of a milling cutter of the PCBA board, so that the finished product rate on the production line is greatly increased.
Description
Technical field
The utility model relate to a kind of semicon industry production equipment, particularly relate to the tool of the cutting action of a kind of SMT of being applied to (surface mounting technology) plate.
Background technology
The development of Along with people's growth in the living standard and IC industrial technology; The production product of SMT (Surface Mounted Technology) tends to little assembling, High Density Packaging and three-dimensional assembling has become the main flow trend that SMT produces gradually, and this just means that the microminiature module must become the main flow trend that follow-up SMT produces.Yet; When the microminiature module is carried out PCBA plate cutting branch plate at the utilization traditional mode, because old tool is the large-size modular design often, when producing; PCBA plate jigsaw spacing is too little, and the individual module after the cutting can't receive fixing in the direction that milling cutter advances fully.Carrying out thin PCBA plate when dividing plate, because the PCBA plate thickness is extremely thin, can't receive fully under the fixing situation in milling cutter direction up and down at same individual module, the PCBA plate receives external force to influence to cause to scrap easily, and this has just influenced the rate of manufacturing a finished product greatly.
For example, a certain monoblock PCB is of a size of 118.2mm * 66.6mm, and thickness is 0.3mm, and whole layout is 32 to win in succession.After cutting finished, single PCB was of a size of 9mm * 9mm, and according to tradition cutting way, pcb board is very easily taken up by milling cutter when minute plate and causes scrapping of PCBA.Scrappage is up to 3%-5%.Those skilled in the art be devoted to develop a kind of can be to the be well on novel tool of branch plate of small size and thin PCBA plate.
The utility model content
The technical problem that the utility model will solve is for the tool that overcomes prior art causes the deficiency of scrapping easily when cutting apart to small size PCBA plate with than thin PCBA plate, and a kind of novel tool is provided.
The utility model solves above-mentioned technical problem through following technical proposals:
A kind of minute plate tool comprises tool base and tool cover plate, and its characteristics are that the tool base is provided with a plurality of cutter bores, and said tool cover plate is provided with a plurality of cutting grooves.
Preferably, the size of said cutting groove is not more than the monolithic PCBA board size after the PCBA plate cuts.
Preferably, said tool cover plate and tool base are through a pivotal connection.
Preferably, said tool base is being provided with a snap close away from pivot pin end, and said tool cover plate is provided with a bonnet lock hole at correspondence position.
Preferably, between said tool cover plate and the PCBA plate to be cut antistatic foam is set.
The positive progressive effect of the utility model is: the technical scheme that the utility model discloses is simple in structure, easy to use, in the milling cutter direction of advance of PCBA plate the PCBA plate is fixed, and has improved the yield rate on the production line greatly.
Description of drawings
Fig. 1 is the structural representation of tool among embodiment of the utility model.
Fig. 2 is the structural representation of the tool under another angle among embodiment of the utility model.
The specific embodiment
The embodiment of the utility model will describe with reference to accompanying drawing.In Figure of description, the element with similar structures or function will be used the components identical symbolic representation.Accompanying drawing for the ease of each embodiment of explanation the utility model, is not to carry out the explanation of exhaustive to the utility model just, neither the scope of the utility model be limited.
Fig. 1 and Fig. 2 show the structural representation of the branch plate tool under specific embodiment of the utility model jointly.In this embodiment, tool base 10 is cuboid, and cuboid is provided with locating hole 12 in position, four angles, thereby tool base 10 is fixed on a certain plane.Tool base 10 centre positions are provided with PCBA plate die 14, and the size after the cutting of the shape of die 14 and PCBA plate module is corresponding, and each small-sized module after making the PCBA plate cut can both obtain following support, is unlikely to unsettled.
In a preferred embodiment, tool cover plate 20 inboards are provided with antistatic foam, each module generation striker situation when preventing that milling cutter from cutting the branch plate.
In use, operating personnel put into tool base 10 with PCBA plate to be cut according to the shape of groove 14, make the shape of PCBA plate and groove reach best fit-state.Buckle tool cover plate 20, lock snap close 18, the PCBA plate is defined in the direction that milling cutter advances, cut through 22 pairs of PCBA plates of cutting groove with milling cutter subsequently.After cutting finishes, open tool cover plate 20, take out the small-sized module of well cutting.
Those skilled in the art is appreciated that equally this device can not only be applied to the cutting of PCBA plate, can be applied in other industry the occasion that need carry out small size or cut than light sheet sheet material equally.
Though more than described the specific embodiment of the utility model, it will be understood by those of skill in the art that these only illustrate, the protection domain of the utility model is limited appended claims.Those skilled in the art can make numerous variations or modification to these embodiments under the prerequisite of principle that does not deviate from the utility model and essence, but these changes and modification all fall into the protection domain of the utility model.
Claims (5)
1. a branch plate tool comprises tool base and tool cover plate, it is characterized in that the tool base is provided with a plurality of cutter bores, and said tool cover plate is provided with a plurality of cutting grooves.
