Background
The existing powder-liquid double-chamber bag (a soft bag of a double-chamber bag for infusion filled with liquid medicine and medicinal powder, wherein the outer side of a powder cavity is welded with an aluminum film for protection) is a high-end soft infusion bag type product, and the soft bag is provided with two chambers and is separated by a middle weak weld. One chamber is filled with liquid medicine, and the other chamber is filled with medicinal powder. The method is also a product with high added value for pharmaceutical factories, and the process control of the product is also stricter. However, the powder therein has high environmental requirements, so a layer of aluminum film is welded on two sides of the powder cavity for protection, and the purpose of aluminum film welding is to protect the powder. The poor welding effect of the aluminum film can also influence the protection effect, and the effect of protecting the powder cannot be achieved. In the prior art, a special penetrating fluid is driven into a sealing cavity between an aluminum film and a medicine bag during leakage detection, the inspection standard is that the penetrating fluid can penetrate into a welding seam if welding is unqualified, the method has low efficiency and inconvenient operation, and a detected product is damaged at the same time. Therefore, the method can only carry out sampling inspection on the products under the offline condition, and cannot detect each product.
Therefore, helium can be filled between the aluminum film and the medicine bag before welding, and the helium generally does not cause adverse effects on people and medicine powder. And filling a certain amount of helium between the aluminum film and the soft bag before the full-automatic aluminum film welding machine finishes welding the aluminum film, and then welding the aluminum film, so that the helium is sealed between the aluminum film and the soft bag. And detecting leakage by using a helium detection device in the subsequent process so as to judge whether the aluminum film is qualified in welding or not through helium leakage detection. If the weld is not effective, the presence of helium can be detected at the perimeter of the bag. The existing aluminum film welding equipment does not have the helium filling function, and whether the product is qualified or not can not be judged timely and effectively.

Detailed Description
The invention will be further described with reference to the following examples:
as shown in fig. 1-3, two room bag aluminium membrane welding of powder liquid fill helium device, including liftable welding top die 1 and fixed welding bed die 5, medicine bag 4 is equipped with mobilizable aluminium membrane sucking disc 2 that send between welding top die 1 and the welding bed die 5 on welding bed die 5, pastes on medicine bag 4 the plane and is equipped with and controls the helium pipe 8 that fills that removes, still is equipped with the pressure aluminium lamina membranacea 9 that can control the translation from top to bottom between welding top die 1 and the welding bed die 5.
The helium filling pipe 8 of the embodiment is fixed on the helium filling pipe fixing plate 7, and the helium filling pipe fixing plate 7 is arranged on the helium filling driver 6; the aluminum pressing diaphragm plate 9 is arranged on a vertical driver 10, and the vertical driver 10 is arranged on a horizontal driver 11.
The helium charging driver 6, the vertical driver 10 and the horizontal driver 11 of the present embodiment are electric cylinders.
The utility model discloses a working process or theory of operation:
firstly, the aluminum film feeding sucker 2 adsorbs the cut aluminum film 3 and conveys the aluminum film to the upper part of the welding lower die 5 to correspond to the die position, and at the moment, the helium filling pipe 8 and the aluminum pressing diaphragm plate 9 are both in the original positions, namely the positions for preventing the aluminum film from interfering with the die and avoiding welding the upper die and the lower die, as shown in figure 1. The helium filling pipe 8 is fixed on the helium filling driver 6 through the helium filling pipe fixing plate 7, the helium filling driver 6 acts to drive the helium filling pipe 8 to move towards the mold, and the helium filling pipe is just attached to the medicine bag 4 and is positioned above the medicine bag 4 after the helium filling pipe is in the position. Then the aluminum film sucking disc 2 drives the aluminum film 3 to move downwards to the position which is jointed with the medicine bag 4. The aluminum pressing diaphragm 9 is fixed on the moving part of the vertical driver 10, and the fixed part of the vertical driver 10 is connected on the moving part of the horizontal driver 11, so that after the horizontal driver 11 acts to drive the aluminum pressing diaphragm 9 to move to the correct position relative to the mold, the vertical driver 10 acts to drive the aluminum pressing diaphragm 9 to move downwards to press the aluminum film 3. A groove avoiding the helium filling pipe 8 is reserved on the aluminum pressing template, the air outlet of the helium filling pipe 8 is pressed between the aluminum film 3 and the medicine bag 4, and a sealed cavity is formed between the aluminum film 3 and the medicine bag 4. At this point, the valve controlling the helium gas inlet is opened and the helium gas is filled into the sealed chamber through the helium gas tube outlet as shown in fig. 2. After the helium filling is finished, the helium filling pipe 8 and the aluminum pressing diaphragm plate 9 respectively return to the initial positions under the driving of the respective drivers. The upper welding mold 1 moves downward to complete welding, and most of the filled helium gas is sealed in the cavity between the aluminum film 3 and the medicine bag 4. And finally, welding the upper die 1 for resetting, resetting the aluminum film feeding sucker 2, and removing one aluminum film.
