Abstract

The utility model discloses an automatic detecting device for a lead frame. The automatic detecting device comprises a bracket, a conveying rail, a detecting camera and a controller, wherein the conveying rail, the detecting camera and the controller are all mounted on the bracket; the conveying rail is arranged right under the detecting camera; and the length of the conveying rail is at least two times of the width of the detecting camera. The automatic detecting device for the lead frame can meet the demand of automatically detecting products and has the advantages of high accuracy, high speed and good stability.

Description

A kind of lead frame automatic detection device
Technical field
The utility model relates to the automated image detection range, relates in particular to a kind of lead frame automatic detection device.
Background technology
Lead frame is as the chip carrier of integrated circuit, be a kind of being electrically connected by means of bonding gold wire realization chip internal circuit exit and outer lead, form the key structure spare of electric loop, it has played the function served as bridge that is connected with outer lead, all needing to use lead frame in the semiconductor integrated package of the overwhelming majority, is basic material important in the electronics and information industry.Lead frame is mainly produced with mould pressing and chemical etching method.
In the prior art, the lead frame production run adopts photoelectric sensor testing product quality, and this detection mode compares traditional contact detection and eye detection method has tangible advantage.But the photoelectric sensor detection method is subject to disturb, and testing process receives only light and blocks as Rule of judgment, and is therefore very limited to the judgement of detected material, requires high to the operating accuracy of the conveying device of carrying detected material.
Summary of the invention
The technical problems to be solved in the utility model provides a kind ofly can accurately judge detected material, the lead frame automatic detection device low to the requirement of conveying device operating accuracy.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: this lead frame automatic detection device comprises support, delivery track, detection video camera and controller, described delivery track, detect video camera, controller is all rack-mount, described delivery track be positioned at detect video camera under, the length of described delivery track is at least the twice that detects the video camera width.
The image detecting apparatus of this utility model can judge whether detected material is qualified by contrasting correct image, it is little that the process of images acquired is influenced by light, therefore can be strong to the judgement of detected material, require low to the operating accuracy of the conveying device of carrying detected material.
As of the present utility model preferred, described frame bottom is provided with the feet of regulating height.Can reach the purpose of adjusting the delivery track operation height by regulating feet, delivery track is better docked with the lead frame production line.
As of the present utility model preferred, described controller comprises touch-screen, and described touch-screen is fixed on the support, and described touch-screen is positioned at the top of detecting video camera.The position of touch-screen is provided with both had been convenient to workman's operation, again testing process was not produced any influence.
The utility model adopts technique scheme: this lead frame automatic detection device can satisfy the requirement new to the automatic detection of product, have accuracy height, speed soon, the advantage of good stability.Judge detected material by contrasting correct image during this lead frame automatic detection device work, it is strong to make that the lead frame automatic detection device has very strong judgement to detected material; Judgement strengthens, and has further reached the purpose of reduction to the operating accuracy of the conveying device of conveying detected material, and the detection cost is reduced greatly.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described in detail.
Fig. 1 is the front view of a kind of lead frame automatic detection device of the utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
As shown in Figure 1, 2, this lead frame automatic detection device comprises the support 1 of a framed structure, on four angles of support 1 bottom, be provided with the feet 2 of regulating height, controller 3 be installed, delivery track is installed at the top of support 1, detects video camera 4 and touch-screen 5 at support 1 middle part.
Feet 2 comprises support column and supporting seat composition.Support column vertically is connected on the support 1, and its outside is provided with screw thread; Supporting seat is provided with screw, and supporting seat is movably connected on the support column by the mode that is threaded.Delivery track comprises that two guide seat 6 and 7, two guide seat 6 of straight line power roller lay respectively at the two ends of straight line power roller 7.Guide seat 6 is provided with two rotating shafts, and two rotating shafts are on the different surface levels, wherein maintains an equal level with the operation height of the approaching rotating shaft of straight line power roller 7 and the operation height of straight line power roller 7.Detect video camera 4 and be fixed on the support 1, and be positioned at the top at straight line roller middle part by column.Be the accuracy that guarantees to detect, the length of straight line power roller 7 is for detecting the twice of camera width.Straight line power roller 7 is provided with motor, and this motor is connected with pinch roller on the straight line power roller 7, is that pinch roller rotates and then can drive lead frame from straight line power roller 7 processes with motor thus.Detect video camera 4 and motor all with control linkage.Input-output device on the controller 3 adopts touch-screen 5, and this touch-screen 5 is fixed on the support 1 by column.Touch-screen 5 is positioned at the top of detecting camera, and the operation height of touch-screen 5 can make things convenient for the workman to operate.
During use, adjust feet 2 guide seat 6 is docked with the production line of lead frame.When lead frame enters straight line power roller 7 under the guiding function of guide seat 6, in straight line power roller 7 course of conveying through detecting the surveyed area below the video camera 4.Detect video camera 4 and straight line power roller 7 and cooperatively interact, when a slice lead frame enters surveyed area fully, detect video camera 4 and just make detecting operation, and testing result is flowed to controller 3.Guide seat 6 outputs of lead frame through surveyed area from being positioned at straight line power roller 7 other ends.Run into lead frame off quality in testing process, delivery track can quit work and give the alarm under the control of controller 3.
