The invention relates to a punching detection device of a lead frame. The punching detection device comprises a fixing seat and a detection rod; the fixing seat is provided with a small round hole and a large round hole which are orderly arranged from top to bottom and are coaxial; the detection rod comprises a spring rod, a lug boss, a probe rod and a probe, which are orderly and coaxially arranged from top to bottom; the spring is sleeved outside the spring rod; the spring rod is arranged in the small round hole; the lug boss is arranged in the large round hole; the diameter of the probe is smaller than that of the hole requiring detection in the lead frame; a cable is connected to the upper end of the detection rod, and the cable is connected to a detector. The punching detection device is suitable for detecting the punching of the lead frame.
Description
Technical field
The present invention relates to a kind of lead frame punching checkout gear.
Background technology
Lead frame needs the many apertures of punching out in process of production on it.Lead frame is accomplished the punching press to these pores through some roads stamping die when carrying out punching.Because the hole is less, the drift of stamping die is thinner, when punching press, fractures easily, in case drift fractures, the pore of this in the 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 lead frame, in later process, 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 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: provide a kind of and can improve detection efficiency and the lead frame punching checkout gear that detects accuracy.
For addressing the above problem, the technical scheme that the present invention adopts is: lead frame punching checkout gear comprises a holder and a test rod; Be disposed with coaxial small sircle hole and big hole each other in the said holder from top to bottom; Said test rod comprises from top to bottom spring lever, boss, feeler lever and the probe of mutual coaxial setting successively, and the outer cover of spring lever is provided with spring, and spring lever is arranged in the small sircle hole; Boss is arranged in the big hole; The diameter of probe is less than the diameter that needs to detect the hole in the lead frame, the upper end connection cable of test rod, cable connection detector.
Above-mentioned lead frame punching checkout gear also comprises insulating sleeve, and insulating sleeve is set in the boss and the feeler lever outside of test rod.
The invention has the beneficial effects as follows: above-mentioned lead frame punching checkout gear; It is simple in structure, easy to use, and the mode that adopts the electronics touch-type to detect 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.

Fig. 1 is a decomposition texture sketch map of the present invention;
Fig. 2 is a sectional structure sketch map of the present invention;
Among the figure: 1, holder, 11, small sircle hole, 12, big hole, 2, test rod, 21, spring lever, 22, boss, 23, feeler lever, 24, probe, 3, spring, 4, cable, 5, insulating sleeve.
The specific embodiment
Through specific embodiment lead frame punching checkout gear of the present invention is done further to describe in detail below.
Like Fig. 1, shown in Figure 2, lead frame punching checkout gear comprises a holder 1 and a test rod 2; Be disposed with coaxial each other small sircle hole 11 and big hole 12 in the said holder 1 from top to bottom; Said test rod 2 comprises from top to bottom spring lever 21, boss 22, the feeler lever 23 of mutual coaxial setting successively and pops one's head in 24, and the outer cover of spring lever 21 is provided with spring 3, and spring lever 21 is arranged in the small sircle hole 11; Boss 22 is arranged in the big hole 12; The diameter of probe 24 is less than the diameter that needs to detect the hole in the lead frame, the upper end connection cable 4 of test rod 2, cable 4 connection detector (not shown)s.
As preferred version, above-mentioned lead frame punching checkout gear also comprises insulating sleeve 5, and insulating sleeve 5 is set in the boss 22 and feeler lever 23 outsides of test rod 2.Insulating sleeve 5 can prevent that feeler lever 23 from contacting with lead frame, and the accuracy that influence detects.
Operation principle of the present invention is: when the punching in the lead frame is detected, this checkout gear is arranged on the top of lead frame, the punching of lead frame arrive this checkout gear under the time; This checkout gear moves down a bit of distance; This distance is not more than probe 24 length, and is accurate like punching in the lead frame, then pops one's head in 24 to stretch in the punching of lead frame; Because the diameter of probe 24 is less than the diameter of punching in the lead frame; 24 can not contact with lead frame so pop one's head in, and detector just can not received Continuity signal yet, and then this punching is qualified; Inaccurate or leak and to dash like punching in the lead frame, when this checkout gear moved down, probe 24 contacted with lead frame, spring 3 contractions, and make line conduction, and detector is received Continuity signal, gives the alarm, promptly this punching is defective.
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 (2)
1. lead frame punching checkout gear; Comprise a holder and a test rod, it is characterized in that: be disposed with coaxial small sircle hole and big hole each other in the said holder from top to bottom, said test rod comprises from top to bottom spring lever, boss, feeler lever and the probe of mutual coaxial setting successively; The outer cover of spring lever is provided with spring; Spring lever is arranged in the small sircle hole, and boss is arranged in the big hole, and the diameter of probe is less than the diameter that needs to detect the hole in the lead frame; The upper end connection cable of test rod, the cable connection detector.
