Abstract
The invention relates to a tool for detecting a lead frame of an optical coupler. The tool which comprises a stamping die body is characterized in that: the upper part of the stamping die body is provided with several bosses; the positions of the bosses correspond with the positions of fine holes in the lead frame of the optical coupler; and the size of the bosses is not greater than the size of the corresponding fine holes. The tool of the invention is suitable for identifying the deformation of non-perforation of the lead frame of the optical coupler.
Description
Technical field
The present invention relates to a kind of not punching distortion identification of photo-coupler lead frame that is used to detect.
Background technology
Be distributed with many pores in the photo-coupler lead frame.The photo-coupler lead frame is accomplished the punching press to these pores through some roads stamping die when producing.Because the hole is less, because of the drift of stamping die is thinner, when punching press, fractures easily, in case drift fractures, this pore in the photo-coupler lead frame will be dashed by leakage; In addition, when the stamping die punching press, the backfill phenomenon appears in scrap easily, and scrap also may drop on the photo-coupler lead frame, in engineering station, back, causes the damage to product.Above-mentioned situation all can cause bad product; The detection operation in road, back all adopts the position of pore in artificial visually examine's photo-coupler lead frame and quantity to detect bad product at present; Lower and the risk that has omission to cause the visitor to tell of its efficient that not only detects, thus can cause bad product to flow in client's hand.
Summary of the invention
Technical problem to be solved by this invention is: a kind of detection frock that can improve detection efficiency and the photo-coupler lead frame that detects accuracy is provided.
For addressing the above problem; The technical scheme that the present invention adopts is: the detection frock of photo-coupler lead frame; Comprise the diel body; Said diel upper part of body is provided with several boss, and the position of boss is corresponding with the position of pore in the photo-coupler lead frame, and the size of boss is not more than the size of corresponding pore.
The invention has the beneficial effects as follows: the detection frock of above-mentioned photo-coupler lead frame, it is simple in structure, easy to use.It can go out salient point on the bad product of photo-coupler lead frame, thereby the tester is come into plain view, and can not only improve detection efficiency, and can improve the accuracy that detects, thereby can prevent that bad product from flowing in client's hand.
Description of drawings
Fig. 1 is the main TV structure sketch map of the detection frock of photo-coupler lead frame of the present invention;
Fig. 2 is the right TV structure sketch map of Fig. 1;
Among the figure: 1, diel body, 2, boss.
The specific embodiment
Through specific embodiment the detection frock of photo-coupler lead frame of the present invention is done further to describe in detail below.
Like Fig. 1, shown in Figure 2; The detection frock of photo-coupler lead frame comprises stamping head body 1, and the bottom of said stamping head body 1 is provided with several boss 2; The position of boss 2 is corresponding with the position of pore in the photo-coupler lead frame, and the size of boss 2 is not more than the size of corresponding pore.
Operation principle of the present invention is: during use; Above-mentioned stamping head body 1 is arranged on the together last of photo-coupler lead frame stamping line; After treating that the punching press of photo-coupler lead frame is accomplished; Re-use 1 pair of photo-coupler lead frame of above-mentioned stamping head body and carry out punching press, if the photo-coupler lead frame is certified products, then boss 2 directly passes the pore of photo-coupler lead frame; Leak the pore that dashes if having in the photo-coupler lead frame; Or scrap backfill phenomenon appears and scrap drops on the photo-coupler lead frame; Then boss 2 can be gone out salient point below this pore, thereby the tester is come into plain view, and can not only improve detection efficiency; And can improve the accuracy that detects, thereby can prevent that bad product from flowing in client's hand.
The above embodiments are the principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used to limit the present invention; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
Claims (1)
1. the detection frock of photo-coupler lead frame; Comprise the diel body; It is characterized in that: said diel upper part of body is provided with several boss, and the position of boss is corresponding with the position of pore in the photo-coupler lead frame, and the size of boss is not more than the size of corresponding pore.
