Description

Technical Field

[0001] The present invention relates to the technical field of matt packaging, and in particular to an automatic intelligent production line and method for matt hydrating needles. Background Art

[0002] Nowadays, hyaluronic acid injection products are very popular. Hyaluronic acid injection is to fill the prepared liquid into the prefilled syringe, and the glass tube of the prefilled syringe is made of transparent material. The measures that need to be taken during the production process of hyaluronic acid injection are to keep the production in darkness, do not turn on the lights, and produce under dark conditions. The reason is that the liquid of hyaluronic acid injection contains a vitamin, sodium hyaluronate and other substances. The vitamin requires protection from light and is sensitive to light. The content will drop faster in normal daylight. It can be slightly better under ordinary incandescent lamp environment, but it will also drop quickly. Other light may cause the degradation of vitamins and the content will drop. This vitamin will degrade even in the light of 100 lux (lux, legal symbol lx).

[0003] At the front end of production, the demand for light is not too strong because the processes are relatively concentrated. However, in the subsequent packaging, the product is exposed for a longer time. Packaging is also a stage in which the product is formed, and there are many details. If it is not well controlled, it may lead to poor appearance, or defective products are not picked out. At present, it is difficult to completely avoid light during the production and subsequent packaging of hyaluronic acid injections, and there is also the problem of how to inspect the samples after production in a completely light-proof state. If conventional packaging and inspection are selected, it is inevitable to carry out them under normal conditions. In this way, light has a greater impact on the vitamins in the liquid, seriously affecting the product quality.

Step 3: Material distribution slope: Move the syringes in the circular section into the material distribution slope, and the syringes gather at the bottom of the material distribution slope; Step 4: Using the position sensor, the PLC control module controls the conveyor belt to stop the box below the lifting mechanism; Step 5: The PLC controller controls the fifth telescopic motor to turn on, and the syringe enters between the first clamping plate and the second clamping plate of the lifting mechanism, and then controls the fifth telescopic motor to turn off, and the lifting mechanism puts the syringe into the containing box; Step 6: The capping mechanism uses a robot to place the cover plate on top of the containing box, and the conveyor belt moves the containing box out of the sealed box to complete the automated production.

10. The method for producing water light needles without light according to claim 9 is characterized in that: In step 6, the containing box is removed from the sealed box and handed over to manual glue sealing and barcode marking operations.
