Description

Technical Field

[0001] The utility model belongs to the technical field of semiconductor packaging test auxiliary devices, and in particular relates to a material waking device suitable for semiconductor plastic packaging black glue. Background Art

[0002] Vinyl is one of the main raw materials for the plastic sealing process. Before it is warmed up, it needs to be stored in a cold storage at a temperature of 0±5℃. It needs to be warmed up 24 hours in advance before each use, and the use time is 48 hours. The warming up and storage conditions are 24±4℃ and 40-60% humidity. Vinyl has strict requirements on the environment for warming up, storage, and use. Vinyl has strict requirements on warming up and shelf life. At present, the traditional operating method in the industry is the shelf awakening method. The material clerk takes the vinyl out of the cold storage according to the production plan, posts the warming up control label, and places it on the vinyl shelf of the corresponding model. When the vinyl is warmed up, it is moved to the usable area, and the operator collects the vinyl from the material clerk for use according to product requirements.

[0003] However, the above-mentioned traditional waking-up method has the following defects: 1. The traditional waking-up method requires independent material handlers to carry the vinyl, which wastes manpower costs; 2. The traditional waking-up method uses a workshop environment for storage, and the temperature and humidity cannot be precisely controlled; 3. The traditional waking-up method requires manual control of the vinyl model, temperature recovery time, and expiration date, which carries the risk of omissions; 4. The traditional waking-up method requires personnel to check the placement of the vinyl, which is prone to the risk of placement errors or wrong collection; 5. The traditional waking-up method requires manual handling of the vinyl, and violent handling may cause the vinyl to break, and if it is used on the product, there will be abnormalities such as insufficient filling; 6. The traditional waking-up method requires manual distribution of the vinyl, and cannot guarantee first-in-first-out, which is prone to accidents. It is easy to cause the vinyl to be scrapped after the expiration of its validity period, thereby increasing material costs; 7. In the traditional material-awakening method, each time the operator collects the vinyl, the material clerk is required to distribute it and register the distribution record, which increases the workload of the material clerk and causes missed registrations; 8. In the traditional material-awakening method, due to manual distribution and registration, when there is a problem with the product, it is difficult to trace it, and the distribution record needs to be searched, which increases the difficulty of abnormal tracing; 9. In the traditional material-awakening method, each time the operator collects the vinyl, the material clerk is required to distribute it, and there is a risk of sending the wrong thing. If it is used on the product, it will cause a large amount of scrap; 10. In the traditional material-awakening method, vinyl is easy to absorb moisture. When it is stored improperly and causes moisture absorption, it cannot be effectively discovered. When the hygroscopic vinyl is used on the product, it will cause a large number of stratification abnormalities. Utility Model Content
