Description
Technical field
The utility model relates to triode checkout equipment technical field, especially the mechanism for testing on the triode Test handler.
Background technology
Shown in Figure 1, at present, the method for testing of part of detecting is to adopt test pawl 100 on the Test handler, and three pin of triode 101 are tested, and it is whether qualified that the data that obtain with test are classified.But old-fashioned test mode is for the triode of picture TO-252/TO-263; Middle pin is very short, occurs the middle pin of test during by conventionally test easily and does not reach the position, causes test result not conform to the actual conditions; Waste product is increased, so meaning that just loses test.
Summary of the invention
It is a kind of simple in structure that the purpose of the utility model is to provide; Utilize the heat radiator of clamping piece roof pressure triode; Because the pin in the middle of the triode links to each other with heat sink; Therefore clamping piece can also be tested triode when compressing triode, with the test ejector sleeve mechanism on the triode Test handler that promotes test mass and accuracy.
For achieving the above object, the utility model adopts following technical scheme:
Test ejector sleeve mechanism on the triode Test handler; Include test pawl, test tracks; Triode is placed on the test tracks, and the pin of the corresponding triode of test pawl touches test, is provided with clamping piece in an end of the heat sink of triode; The heat sink of clamping piece roof pressure triode, clamping piece is by air cylinder driven.
The external part of the axis of the piston of said cylinder promotes an ejector sleeve seat, and the ejector sleeve seat is installed on the guide rail, and the ejector sleeve seat drives the some groups of triodes that the clamping piece roof pressure is different.
The outer end of said ejector sleeve seat is formed with two parallel lead arms, and lead arm connects a cross bar, and cross bar is parallel with test tracks; Some groups of clamping pieces are connected cross bar through contiguous block respectively, and cross bar is provided with axis hole, and shaft hole sleeve is connected to the ejector sleeve axle, and the ejector sleeve axle also wears in the through hole that is installed on contiguous block, between cross bar and contiguous block, is provided with the ejector sleeve axle sleeve and props up the top, and the ejector sleeve axle sleeve is set on the ejector sleeve axle.
After adopting said structure; The beneficial effect that the utility model obtains is: triode is when test, and the test pawl is to three pin tests the time, also adopts the clamping piece pair and the heat sink of interim pins homopolarity to carry out engaged test; Make test more accurate, thereby reduce rejection rate.
The utility model advantage again is simple in structure, and is scientific and reasonable, makes easily; Cost is low, and clamping piece is flexible, easy and simple to handle by cylinder control; Dirigibility is good, and it is also quite convenient to safeguard, has promoted the operation ratio and the operability of the test ejector sleeve mechanism on the triode Test handler greatly.
Description of drawings:
Accompanying drawing 2 is the perspective view of the utility model;
Accompanying drawing 3 is the utility model STRUCTURE DECOMPOSITION synoptic diagram;
Front schematic view when accompanying drawing 4 is the work of Fig. 2.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further specified:
Consult Fig. 2,3, shown in 4, be preferred embodiment structural representation, the test ejector sleeve mechanism on the relevant triode Test handler of the utility model for the utility model; Include test pawl 1, test tracks 2; Triode 3 is placed on the test tracks 2, and the pin of test pawl 1 corresponding triode 3 touches test, is provided with clamping piece 4 in an end of the heat sink of triode 3; The heat sink of clamping piece 4 roof pressure triodes 3, clamping piece 4 is driven by cylinder 5.
When triode 3 is entered test tracks 2, block by thimble, test pawl 1 begins three pin of triode 3 are tested; Simultaneously the power that provided by cylinder of clamping piece 4 makes clamping piece 2 compress an end of the heat sink of triode, makes the clamping piece pair and the heat sink of interim pins homopolarity carry out engaged test, reaches the pin of crura intermedium homopolarity is tested; Thereby reduce the drawback that the test pawl does not reach on traditional approach; Make test more accurate, thereby reduce rejection rate, improve the quality that detects.
Fig. 2,3, shown in 4; In the present embodiment, the external part of the axis of the piston of cylinder 5 promotes an ejector sleeve seat 6, among the figure; Ejector sleeve seat 6 rear ends are provided with connecting portion and are connected with the axis of the piston of cylinder 5; Be arranged with slidably sliding sleeve 51 on the axis of the piston of cylinder 5, attaching nut interlocking on the sliding sleeve 51 and form the connecting portion that annular groove comes clamping ejector sleeve seat 6 reaches and is fixed together; Be provided with corresponding spacing bolster in the front and back of sliding sleeve 51, during real work, because the difference of the physical dimension of triode; So; After whole ejector sleeve mechanism for testing assembles, can regulate spacing bolster, and then reach the amplitude of stretching out of the axis of the piston of cylinder 5 according to different triodes; Thereby realize to regulate the final position that clamping piece is pushed down triode, make that so whole ejector sleeve mechanism versatility is stronger.Fig. 2,3, shown in 4, ejector sleeve seat 6 is installed on the guide rail 7, moves more steadily, the outer end of ejector sleeve seat 6 is formed with two parallel lead arms 61, lead arm 61 connects a cross bar 8, cross bar 8 is parallel with test tracks 2; Some groups of clamping pieces 4 are connected cross bar 8 through contiguous block 41 respectively, and cross bar 8 is provided with axis hole 81, and axis hole 81 is socketed on ejector sleeve axle 9; Ejector sleeve axle 9 also wears in the through hole that is installed on contiguous block 41, between cross bar 8 and contiguous block 41, is provided with 91 tops of ejector sleeve axle sleeve, and ejector sleeve axle sleeve 91 is set on the ejector sleeve axle 9; Ejector sleeve axle 9 plays the guide pillar effect; Cross bar 8 straight lines are moved, come ejection contiguous block 41, drive the some groups of triodes 3 that clamping piece 4 roof pressures are different thereby reach through ejector sleeve axle sleeve 91.
The beneficial effect that the utility model obtains is: simple in structure, scientific and reasonable, to make easily, and cost is low, and clamping piece is flexible by cylinder control, and easy and simple to handle, dirigibility is good, and it is also quite convenient to safeguard; Triode when the test pawl is tested three pin, also adopts clamping piece that the heat sink of middle pin homopolarity is carried out engaged test when test, makes test more accurate, thereby reduces rejection rate.
Aforementioned is the explanation of the utility model structure being done preferred embodiment, and is can do multiple variation or modify embodiment according to the design spirit of the utility model.So, the obviously replacement that can do for the technological personage who is familiar with this area with modify, will be incorporated within the claim that the utility model advocates.
