The invention provides a light source plate of a direct type panel lamp and a rapid fixing method, which can eliminate the waiting time of glue solidification in the production process of the direct type panel lamp and avoid various risks of loosening, deviation and falling of a light source plate assembly in the production process of the direct type panel lamp in the original production technology.
Description
Technical Field
The invention relates to the technical field of panel lamp production, in particular to a direct type panel lamp light source plate and a rapid fixing method.
Background
In the current industrial situation, three schemes exist in the production process of the direct type panel lamp;
according to the first scheme, the product is glued until the package is completed, the whole process flow is not specially used for glue solidification, and the production defects of the scheme are more: if the light source plate is deviated, the different color is generated; for example, the repair rate in the production process is high; for example, the production efficiency is 1300 highest in one day; if the light source plate falls off in the hands of the customer, the customer complaint is generated, and the like. The production capacity of the scheme is generally 1300 in 27 people per day. Scheme two, compare scheme one and increased the action of a glue solidification at the back end of product production, optimize the hidden danger of having solved the light source board off normal and dropping that appears assembling the back end, nevertheless also have certain drawback: turnover is needed if glue curing products are added; hardware facilities for increased curing if needed; if the assembly process of the front section is carried out, the light source plate is separated or deviated; the production period is prolonged, and the time for curing the glue is equal to 4 hours. The production capacity of the scheme is generally 1200 per day for 27 persons. Scheme three, compare scheme two and shifted to the technological scheme of glue solidification after installing the light source board, the light source board has just been installed this moment, carries out the glue solidification and can effectively avoid droing and the off normal of light source board, but partial drawback still exists: hardware facilities such as solidification cannot solve; if the production period is prolonged, the glue needs to be solidified for 4 hours, and the like. The production capacity of the scheme is generally 1500 in 27 people per day. The third scheme is gradually optimized for the first scheme, but the hardware investment amount for product turnover solidification in the production process of the direct type panel lamp can be increased, the corresponding production period is prolonged, the capacity is insufficient, and the long-term development of a factory for producing the products is not facilitated. Under the current situation that the market is increasingly competitive, another optimization scheme which can reduce the cost is urgently needed to be found for replacement.
Therefore, the direct type panel light source plate and the rapid fixing method are designed, the time flow of glue solidification is eliminated through the change of the process scheme, the labor cost is reduced, the product productivity is improved, and the production period is shortened.
Chinese patent application publication No. CN208268869U, the publication date is 2018, 12 months and 21 days, entitled "a straight following formula panel light", discloses a straight following formula panel light, including face frame, underframe and light source plate, the underframe with the face frame is for dismantling the connection, the underframe is equipped with the bottom plate, the bottom plate inboard is equipped with many parallel arrangement's bar groove, the light source plate is many, and installs respectively many in the bar inslot, be equipped with a plurality of LED light source on the light source plate, and every LED light source covers there is a lens. The utility model discloses a set up a plurality of parallel arrangement's bar groove on the bottom plate of underframe, its light source board is installed at the bar inslot, and is convenient spacing and fixed, but also can play the effect of strengthening rib to still be equipped with lens on the LED light source, can reach the diffuser plate through the lens refraction like this on, thereby realize that less LED quantity can satisfy the effect of illumination demand again. However, the direct type panel lamp of the patent still has the above problems.
