Abstract
The present invention discloses a device for detecting the sealing of an ultrasonically welded seam. The device comprises a laterally placed clamping box. The top end of the clamping box is opened, and a cavity is formed in the clamping box. A concavely installation table is formed at the opening end of the clamping box, and an assembly hole which communicates with the cavity is formed at a side end face in a length direction. A cover plate and a metal foil are orderly packaged on the concavely installation table through a vacuum cement. A plurality of through holes are formed on the cover plate along a straight line. The linear ultrasonically welded seams on the metal foil and the through holes are in displacement. The assembly hole is provided with a nozzle, and the junction of the nozzle and the clamping box is sealed by the vacuum cement. According to the device, the metal foil is fixed through the clamping box and the cover plate, the sealing of the junction is raised further through the vacuum cement, the clamping box is evacuated by a helium leak detection instrument through the gas nozzle to form negative pressure in the cavity, and then the sealing of the ultrasonically welded seam is detected through a helium gun.
Description
Technical field
The invention belongs to weld seam device for detecting sealability, be specifically related to the pick-up unit of weld seam sealing after a kind of ultrasonic soldering.
Background technology
Ultrasonic soldering is the body surface utilizing dither wave loops to weld to two need, when pressurizeing, makes the mutual friction of two body surface phases and the fusion that formed between molecular layer.Ultrasonic metal welding can carry out strip welding to the sheeting of the non-ferrous metals such as copper, silver, aluminium, nickel.
Because aluminium foil itself has excellent sealing property, therefore it is more and more wider in the application of the industries such as food, medicine, chemical industry, gas sampling analysis.Only for aluminium foil in the present invention, a lot of occasion needs to be spliced by multiple aluminium foils, and this splicing much completes by the roll welding of ultrasound wave straight line, but, form the sealing property of long straight weld after welding, there is no effective method at present and detect.
Summary of the invention
The present invention, for solving prior art Problems existing and proposing, its objective is the pick-up unit providing weld seam sealing after a kind of ultrasonic soldering.
Technical scheme of the present invention is: the pick-up unit of weld seam sealing after a kind of ultrasonic soldering, comprise horizontal placement, open top, the inner clamping box forming cavity, clamping box openend forms indent assembly bench, the side end face of length direction forms the pilot hole with cavity connects, indent assembly bench is packaged with cover plate, tinsel successively by vacuum cement, cover plate linearly forms multiple through hole, the ultrasonic weld seam of wire and through hole sequence on tinsel, pilot hole is provided with valve, and valve and clamping box junction are sealed by vacuum cement.
Described tinsel material is copper or silver or aluminium or nickel.
The present invention realizes fixing tinsel by clamping box, cover plate, and the sealing of binding site is improved further by vacuum cement, helium leak detector is found time by valve to clamping box inner chamber thus forms negative pressure in the lumen, then carries out sealing propertytest by helium spray gun to ultrasonic weld seam.

Embodiment
Below, with reference to drawings and Examples, the present invention is described in detail:
As shown in Fig. 1 ~ 3, the pick-up unit of weld seam sealing after a kind of ultrasonic soldering, comprise horizontal placement, open top, the inner clamping box 1 forming cavity, clamping box 1 openend forms indent assembly bench 8, the side end face of length direction forms the pilot hole 9 with cavity connects, indent assembly bench 8 is packaged with cover plate 2 successively by vacuum cement 3, tinsel 5, cover plate 2 is linearly formed multiple through hole 7, the ultrasonic weld seam 6 of wire and through hole 7 sequence on tinsel 5, pilot hole 9 is provided with valve 4, valve 4 and clamping box 1 junction are sealed by vacuum cement 3.
Described tinsel 5 material is copper or silver or aluminium or nickel.
Described cover plate 2, tinsel 5 overall size are less than the size of indent assembly bench 8.Guarantee cover plate 2, tinsel 5 can be encased in indent assembly bench 8.
Cover plate 2, sealed by vacuum cement 3 between tinsel 5 and indent assembly bench 8, between the pilot hole 9 of valve 4 and clamping box 1, vacuum cement 3 seals, and when can ensure to be vacuumized by valve 4 pairs of inner chambers, entirety has good impermeability.
The course of work of the present invention is as follows:
(I) uses metal material processing clamping box 1, clamping box 1 openend forms indent assembly bench 8, the side end face of length direction forms the pilot hole 9 with cavity connects, the aperture of pilot hole 9 and the external diameter of valve 4 adapt, cover plate 2 is that about 1mm metal sheet processes by thickness, bore multiple through holes 7 of row's diameter 1 ~ 2mm in the position of cover plate 2 disalignment, between holes, spacing is 5 ~ 10cm.The size of cover plate 2 is fixed with ultrasonic weld seam 6 length of tinsel 5 to be measured, and be bonded on indent assembly bench 8 by cover plate 2 with bonding agent after completion of processing, valve 4 is inserted in pilot hole 9, then seals with vacuum cement 3.
(II) cuts out a tinsel 5 with ultrasonic weld seam 6 measure-alike with it according to the size of cover plate 2, and ultrasonic weld seam 6 is positioned on the center line of tinsel 5.
Tinsel 5 to be measured is placed on the surface of cover plate 2 by (III), seals between the surrounding of tinsel 5 and cover plate 2, indent assembly bench 8 with a circle vacuum cement 3.
(IV) vacuumizes from the inner chamber of valve 4 to clamping box 1 with helium leak detector.Tinsel 5 is attached on cover plate 2, can not take out flat by tinsel 5 when vacuumizing.And stagger mutually in the position of ultrasonic weld seam 6 and through hole 7, ultrasonic weld seam 6 can not cause damage owing to vacuumizing.
(V), when the negative pressure in clamping box 1 inner chamber reaches appointment numerical value, visits undetected survey with helium spray gun to ultrasonic weld seam 6.
The present invention realizes fixing tinsel by clamping box, cover plate, and the sealing of binding site is improved further by vacuum cement, helium leak detector is found time by valve to clamping box inner chamber thus forms negative pressure in the lumen, then carries out sealing propertytest by helium spray gun to ultrasonic weld seam.
