The detecting device comprises a fixing base and a detection rod, a small round hole and a large round hole which are coaxial are arranged in the fixing base successively from top to bottom, the detection rod comprises a spring rod, a boss, a probe rod and a probe which are coaxially arranged successively from top to bottom, a spring is sleeved on the outside of the spring rod which is arranged in the small round hole, the boss is arranged in the large round hole, the diameter of the probe is smaller than diameters of holes needed to be detected in the lead frame, and a cable is connected to the upper end of the detection rod and connected with a detector. The device is suitable for detecting punch holes of the lead frame.
Description
Technical field
The utility model 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 finished punching press to these pores by some roads stamping die when carrying out punching.Because the hole is less, the drift of stamping die is thinner, fractures easily when punching press, in case drift fractures, the pore of this in the lead frame will be leaked punching; In addition, when the stamping die punching press, the backfill phenomenon appears in scrap easily, and scrap also may drop on the lead frame, causes the damage to product in later process.Above-mentioned situation all can cause bad product, the detection operation in road 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 the undetected visitor of causing to tell of its efficient that not only detects, thus can cause bad product to flow in client's hand.
The utility model content
Technical problem to be solved in the utility model is: a kind of lead frame punching checkout gear that can improve detection efficiency and detect accuracy is provided.
For addressing the above problem, the technical solution adopted in the utility model is: lead frame punching checkout gear, comprise a holder and a test rod, be disposed with from top to bottom mutually coaxial small sircle hole and big hole in the described holder, described test rod comprises from top to bottom the spring lever of successively mutual coaxial setting, boss, feeler lever and probe, the outer cover of spring lever is provided with spring, 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, the cable connection detector.
Above-mentioned lead frame punching checkout gear also comprises insulating sleeve, and insulating sleeve is set in boss and the feeler lever outside of test rod.
The beneficial effects of the utility model are: 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.
Description of drawings
Fig. 1 is decomposition texture schematic diagram of the present utility model;
Fig. 2 is sectional structure schematic diagram of the present utility model;
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
Below by specific embodiment the utility model lead frame punching checkout gear is described in further detail.
Such as Fig. 1, shown in Figure 2, lead frame punching checkout gear, comprise a holder 1 and a test rod 2, be disposed with from top to bottom mutually coaxial small sircle hole 11 and big hole 12 in the described holder 1, described test rod 2 comprises from top to bottom the spring lever 21 of successively mutual coaxial setting, boss 22, feeler lever 23 and probe 24, the outer cover of spring lever 21 is provided with spring 3, 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 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 impact detects.
Operation principle of the present utility model 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 the length of probe 24, accurate such as punching in the lead frame, then pop one's head in and 24 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, detector just can not received Continuity signal yet, and then this punching is qualified; Inaccurate or leak punching such as punching in the lead frame, when this checkout gear moved down, probe 24 contacted with lead frame, spring 3 contractions, and so that line conduction, detector is received Continuity signal, gives the alarm, namely this punching is defective.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used for restriction the utility model; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
Claims (2)
1. lead frame punching checkout gear, comprise a holder and a test rod, it is characterized in that: be disposed with from top to bottom mutually coaxial small sircle hole and big hole in the described holder, described test rod comprises from top to bottom spring lever, boss, feeler lever and the probe of successively mutual coaxial setting, the outer cover of spring lever is provided with spring, 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, the cable connection detector.
