Background technology
In the semiconductor test Packaging Industry, the band Test handler is a kind of a kind of equipment that transistor is tested and the specification product in the transistor filtered out according to test result.Its course of work is: transistor is by UV (ultraviolet ultraviolet ray) film frame material loading, transistor carry out that lot number is determined and the direction location after enter on the test platform, this test platform is by the CD-ROM drive motor of X-Y-Z direction disposed thereon, driving the testing needle that test platform moves on the cover plate that realization is arranged on the transistor AND gate on the test platform test platform top aims at, after the transistor AND gate testing needle is aimed at, test platform moves up under the effect of CD-ROM drive motor, realize that testing needle contacts with transistorized pin contraposition, and transistor detected, the test board of the upper surface setting of above-mentioned cover plate and Test Host mainly are that the control testing needle carries out work, and testing result carried out record, after detection finishes, according to test result, adopt mechanical arm that product qualified in the transistor is selected, carry out the light inspection again, carry out braid so that enter subsequent processing.
Above-mentioned band Test handler is in the process of work, transistor is arranged on the band, band is provided with lead frame, transistorized running is to realize by the conversion of both arms to band, both arms are provided with a plurality of suckers, by sucker lead frame is picked up, thereby realize that both arms are to transistorized running.
But the sucker on the both arms can only pick up the lead frame of some surfacings, if the surface irregularity of lead frame, the sucker on the both arms can not adsorb whole lead frame well so, so just do not reach the transistorized purpose of transportation.So above-mentioned sucker is very high to the flatness requirement of lead frame, lead frame need reach certain flatness and could be picked up, and has increased the manufacturing requirement to lead frame.
The utility model content
In view of this, the utility model provides a kind of band Test handler sucker, by in this sucker spring being set, has realized the lead frame of some surface irregularities is adsorbed, and has reduced the flatness requirement of sucker to lead frame.
In order to achieve the above object, the utility model embodiment provides following technical scheme:
A kind of band Test handler sucker comprises:
Shell;
Be set in the described shell, and the vacuum shaft that can in described shell, slide up and down, this vacuum shaft has center pit, and the top of this vacuum shaft is provided with Air suction pipe joint, and the interface of this Air suction pipe joint communicates with described center pit;
Be set in the bottom of described vacuum shaft, and the vacuum cup that communicates with described center pit, it is characterized in that, be provided with positioning table in the described shell;
Also comprise being set on the described vacuum cup, and the spring between described vacuum shaft and described shell, an end of described spring contacts with described positioning table location, and the other end is positioned on the described vacuum cup.
Preferably, the band Test handler is with in the sucker, and described positioning table is the circular orientation platform.
Preferably, the band Test handler is with in the sucker, and described Air suction pipe joint is arranged on the top of described center pit by being threaded.
Preferably, the band Test handler is with in the sucker, and the outer wall of described shell is provided with sets up the stage, and this is set up the stage and is provided with threaded hole.
As shown from the above technical solution, the utility model embodiment provides the band Test handler with in the sucker, between vacuum shaft and shell, spring is set, and the inwall of shell is provided with positioning table, because vacuum shaft can slide up and down in the enclosure, and spring housing is located on the vacuum cup, said structure makes that vacuum cup can be flexible up and down with respect to shell, so the sucker of this structure can adapt to the lead frame of surface irregularity owing to its vacuum cup can stretch, a plurality of suckers on both arms cooperatively interact according to the surface of lead frame, make each sucker lead frame be picked up by the flexible realization of self, thereby realize the picking up of the lead frame of some surface irregularities, and then reduced the manufacturing requirement of lead frame.
Description of drawings
The band Test handler that Fig. 1 provides for the utility model embodiment structural representation of sucker;
Fig. 2 is the cut-open view of Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is a part of embodiment of the present utility model, rather than whole embodiment.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skills are obtained under the prerequisite of not making creative work belongs to the scope that the utility model is protected.
The utility model embodiment discloses a kind of band Test handler sucker, has realized the irregular lead frame in surface is adsorbed, and then has reduced the requirement of sucker to the flatness of lead frame.
Please refer to accompanying drawing 1-2, the band Test handler that Fig. 1 provides for the utility model embodiment structural representation of sucker, Fig. 2 is the sectional structure synoptic diagram among Fig. 1.
The band Test handler sucker that the utility model embodiment provides comprises shell 2, vacuum shaft 5, Air suction pipe joint 1, vacuum cup 4 and spring 3, wherein:
