Abstract

The utility model discloses a waste marking tool for lead frames, which comprises a bottom plate (1), limiting rods (2) and a flat panel (3). The bottom plate (1) is provided with two limiting rods (2). The flat panel (3) is provided with two through holes (4). The diameters of the through holes (4) are equal to the diameters of the limiting rods (2). The flat panel (3) is parallel to the bottom plate (1), and the longer edges of the flat panel (3) are parallel to the longer edges of the bottom plate (1). The two limiting rods (2) are configured to respectively pass through the two through holes (4) so as to fix the flat panel (3) onto the bottom plate (1). The middle part of the flat panel (3) is provided with a rectangular slot (5). The flat panel (3) is provided with scale marks (6) along the shorter side and the longer side of the rectangular slot (5) respectively. Different Arabic numbers are etched between every two adjacent scale marks (6). The waste marking tool for lead frames is simple in structure and labor-saving. By means of the waste marking tool for lead frames, the operation of workers is facilitated, and unqualified products can be accurately rejected.

Description

A kind of lead frame waste product mark frock
Technical field
The utility model relates to the technical field of waste product removing in electronics production industry, particularly a kind of lead frame waste product mark frock.
Background technology
At present, in most of electronic enterprises, workman need to be divided into rectangular-shaped tablet the product of a plurality of little bulks by cutting equipment, the method of processing is first gridding on tablet surface, again by cutting equipment along grid line feed, the final bulk product that obtains, the bulk product processing is mainly used in subsequent production.Due to some smaller part position defectiveness on tablet, be illustrated in figure 1 the structural representation of defective tablet, workman will mark with crayon on this position, after cutting equipment has cut whole tablet, workman takes out defective product according to mark, yet, cutting equipment is along in grid feed process, the material bits that cutting produces can cover mark completely, cause workman to be difficult to search out defective product, waste workman's time and efforts, finally caused product used to be used as waste disposal, increased production cost.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, provide a kind of simple in structure, save workman's amount of labour, facilitate workman to operate, can accurately reject the lead frame waste product mark frock of bad product.
The purpose of this utility model is achieved through the following technical solutions: a kind of lead frame waste product mark frock, it comprises base plate, gag lever post and flat board, on described base plate, be provided with two gag lever posts, two gag lever posts are all perpendicular to base plate setting, the diameter that is provided with two through holes and two through holes on flat board is all identical with the diameter of gag lever post, flat board is parallel to the long limit setting that base plate and dull and stereotyped long limit are parallel to base plate, flat board is fixed on base plate through two gag lever posts respectively by two through holes, dull and stereotyped middle part is provided with rectangular channel, on flat board and along being provided with graduation mark on the minor face of rectangular channel and long limit, between every adjacent two graduation marks, be all carved with different Arabic numerals.
Described base plate and flat board be rectangular shape all.
Two described through holes arrange along dull and stereotyped long limit, and the diameter of two through holes is 1.5mm.
Described base plate and dull and stereotyped thickness are 5mm.
The long limit of described rectangular channel is parallel to dull and stereotyped long limit and arranges.
The utlity model has following advantage: flat board of the present utility model is fixed on base plate through two gag lever posts respectively by two through holes, dull and stereotyped middle part is provided with rectangular channel, on flat board and along being provided with graduation mark on the minor face of rectangular channel and long limit, between every adjacent two graduation marks, be all carved with different Arabic numerals, gridding on tablet in advance before processing, workman leans against the long limit of tablet and minor face respectively long limit and the minor face of rectangular channel, and guarantee that in horizontal direction and vertical direction, grid is aimed at respectively the dull and stereotyped Arabic numerals of growing limit and minor face, now, manually read the coordinate of defectiveness grid, again by under this coordinate record, then use cutting equipment along grid line feed, after having cut, workman only needs to find fast defective product according to the coordinate of recording, therefore, facilitated workman to choose fast defective product, thereby reject accurately bad product, saved workman's the amount of labour.

In figure, 1-base plate, 2-gag lever post, 3-is dull and stereotyped, 4-through hole, 5-rectangular channel, 6-graduation mark.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, protection range of the present utility model is not limited to the following stated:
As shown in Figures 2 and 3, a kind of lead frame waste product mark frock, it comprises base plate 1, gag lever post 2 and dull and stereotyped 3, on described base plate 1, be provided with two gag lever posts 2, two gag lever posts 2 all arrange perpendicular to base plate 1, the diameter that is provided with two through holes 4 and two through holes 4 on dull and stereotyped 3 is all identical with the diameter of gag lever post 2, the diameter of two through holes 4 is 1.5mm, the long limit that the dull and stereotyped 3 long limits that are parallel to base plate 1 and dull and stereotyped 3 are parallel to base plate 1 arranges, dull and stereotyped 3 are fixed on base plate 1 through two gag lever posts 2 respectively by two through holes 4, gag lever post 2 has prevented from rocking in the cut process of tablet, dull and stereotyped 3 middle part is provided with rectangular channel 5, on dull and stereotyped 3 and along being provided with graduation mark 6 on the minor face of rectangular channel 5 and long limit, between every adjacent two graduation marks 6, be all carved with different Arabic numerals, Arabic numerals on dull and stereotyped 3 long limits are abscissa, Arabic numerals on dull and stereotyped 3 minor faces are ordinate.
As shown in Figure 2, base plate 1 and dull and stereotyped 3 is rectangular shape all, and base plate 1 is 5mm with the thickness of flat board 3, and the long limit on two through hole 4 edges dull and stereotyped 3 arranges, and the long limit of rectangular channel 5 is parallel to dull and stereotyped 3 long limit setting.
The course of work of the present utility model is as follows: gridding on tablet in advance before processing, workman leans against the long limit of tablet and minor face respectively long limit and the minor face of rectangular channel 5, and guarantee that in horizontal direction and vertical direction, grid is aimed at respectively the dull and stereotyped Arabic numerals of growing limit and minor face, now, manually read the coordinate of defectiveness grid, again by under this coordinate record, then use cutting equipment along grid line feed, after having cut, workman only needs to find fast defective product according to the coordinate of recording, facilitated workman to choose defective product, thereby reject accurately bad product, saved workman's the amount of labour.
