Technical field
The present invention relates to clamping device of circuit board, particularly relate to a kind of Inflatable air bag type circuit board direct plug-in element stationary fixture.
Background technology
In board production, when direct insertion electronic component is welded, for raising the efficiency, need disposable needing the direct insertion element of welding to be inserted on circuit board, then sticking with the circuit board bottom surface of element upward, thus need stationary fixture and remove inverted electronic component on fixing circuit board, make it can not come off from circuit board.
This type of fixture existing mostly is specialized type at present, namely according to the height of the direct plug-in element in a certain particular circuit boards, the hole groove that the carve depth is different on mould, and stick cushion at ad-hoc location, and then be fixed on fixture stick with element circuitry plate, circuit board bottom surface upward time, depth difference hole groove just can withstand just different direct plug-in element one by one, makes it come off.The fixture process-cycle of this specialized type is long, and circuit board is fixing convenient not, and when circuit board or element have some modifications, again need make fixture, easily cause fixture to waste, and is unfavorable for improving board production efficiency, is also unfavorable for saving production cost.
Summary of the invention
The object of the invention is to the shortcoming and defect overcoming above-mentioned prior art, the Inflatable air bag type circuit board direct plug-in element stationary fixture that a kind of structure is simple, versatility is good is provided.
The present invention is achieved through the following technical solutions:
A kind of Inflatable air bag type circuit board direct plug-in element stationary fixture, comprises base, movable backstay, fixed backstay guide rail, air bag array; An end of described base is provided with inflation inlet, is distributed with base air flue in the inside of base, and base two parallel side is symmetrically distributed with two movable backstay guide rails.
Described movable backstay string has the B-mode bearing that two structures are identical, and movable backstay is slidably arranged on movable backstay guide rail, movable backstay is provided with movable backstay positioning knob and fixes; Described B-mode bearing is provided with B-mode bearing positioning knob, B-mode support spring bar that structure is identical, and B-mode bearing sliding is arranged on movable backstay; Described fixed backstay guide rail is arranged on another end of base, and fixed backstay slide is fitted together to the identical A type bearing of two structures.
Described A type bearing side is provided with A type bearing positioning knob, A type support spring bar that structure is identical, and A type bearing sliding is arranged on fixed backstay guide rail; Cone shape identical with A type bearing being provided with structure of described B-mode bearing determines plate cone.
Described air bag array is formed by multiple extension airbag array distribution, and each extension airbag is connected with base air flue by air bag air admission hole; The side straps fold of described extension airbag.
This Inflatable air bag type circuit board direct plug-in element stationary fixture, compared with prior art, not only simple and compact for structure, versatility good, and is applicable to the fixing of the direct insertion element of multiple circuit board, and easy for installation, be beneficial to and enhance productivity and the advantage such as cost-saving.
Accompanying drawing explanation
Fig. 1 is structural upright schematic diagram of the present invention.
Fig. 2 is Fig. 1 cross-sectional view.
Fig. 3 is the extension airbag structural representation shown in Fig. 1.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is more specifically described in detail.
Embodiment
As shown in Figure 1 and Figure 2.A kind of Inflatable air bag type circuit board direct plug-in element of the present invention stationary fixture, comprises base 1, movable backstay 3, fixed backstay guide rail 4, air bag array 7; An end of described base 1 is provided with inflation inlet 14, is distributed with base air flue 18 in the inside of base 1, and base 1 liang of parallel side is symmetrically distributed with two movable backstay guide rails 2; Described movable backstay 3 string has the B-mode bearing 9 that two structures are identical, and movable backstay 3 is slidably arranged on movable backstay guide rail 2, movable backstay 3 is provided with movable backstay positioning knob 8 and fixes;
Described B-mode bearing 9 is provided with B-mode bearing positioning knob 10, B-mode support spring bar 11 that structure is identical, and B-mode bearing 9 is slidably arranged on movable backstay 3; Described fixed backstay guide rail 4 is arranged on another end of base 1, and fixed backstay guide rail 4 sliding gomphosis has the A type bearing 6 that two structures are identical; Described A type bearing 6 side is provided with A type bearing positioning knob 5, A type support spring bar 12 that structure is identical, and A type bearing 6 is slidably arranged on fixed backstay guide rail 4;
Cone shape identical with A type bearing 6 being provided with structure of described B-mode bearing 9 determines plate cone 19,20; B-mode support spring bar 11 and A type support spring bar 12 can produce under the effect of spring 15,16 to pressure, determining plate boring fixing circuit board (not shown) under 19,20 actings in conjunction with cone shape.Cone shape determine plate cone 19,20 advantages be, be not limited to the size of mounting-positioning holes on circuit board, can well circuit board be fixed yet.
As shown in Figure 3.Described air bag array 7 is formed by multiple extension airbag 13 array distribution, and each extension airbag 13 is connected with base air flue 18 by air bag air admission hole 17.The side straps fold of extension airbag 13, under not inflation situation, extension airbag 13 can shrink along fold, can stretch under inflation situation along fold, produces holding power upwards.
For the circuit board that will weld, first regulate the position of movable backstay 3 with A type bearing 6, B-mode bearing 9, make four on these four bearings cone shape mounting-positioning holes determining plate cone 19,20 alignment circuit plates, and screw relevant positioning knob (as A type bearing positioning knob 5, movable backstay positioning knob 8, B-mode bearing positioning knob 10) and make movable backstay 3 and A type bearing 6(two), B-mode bearing 9(two) fixing.Then circuit board is taken off, plug the element needing welding, again the end of the present invention upward, the mounting-positioning holes of the circuit board sticking with element is aimed at and cone shapely determine plate and bores and 19,20 to load onto, then stir B-mode support spring bar 11 and circuit board fixed by A type support spring bar 12.Now still keep the end of the present invention upward, then in base air flue 18, enough air are filled with by inflation inlet 14, each extension airbag 13 is stretched, thus withstand the element that circuit board does not weld, at this moment again the present invention is just put, on such circuit board, inverted element would not fall down, and then enters next step welding sequence.
As mentioned above, just the present invention can be realized preferably.
Embodiments of the present invention are not restricted to the described embodiments; other are any do not deviate from Spirit Essence of the present invention and principle under do change, modification, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection scope of the present invention.
