A baking milliliter for PCB circuit boards

Abstract

The utility model relates to a baking thousand-layer rack for PCB, which comprises a transfer carrier vehicle, a baking vehicle and a thousand-layer rack. A transfer vehicle includes an insulated floor, Protect the bezel and movable baffle, A roast truck comprises a drying chassis and a plurality of heat-resistant casters, A loudspeaker frame include handrails, Fixed strips and a plurality of PCBboards are shelved on the screen frame, the first end of the fixing strip is mounted on the drying chassis, the armrest is mounted on the second end of the fixing strip, A plurality of flip holes arearranged on the fixing strip, the plurality of flip holes are sequentially arranged in a direction from a first end of the fixing strip to a second end of the fixing strip, By setting up the transfercarrier, Baking trucks and millennia racks, The thousand-layer rack is arranged on the baking vehicle, the PCB is spread on the thousand-layer rack, the baking vehicle and the thousand-layer rack aresent into the oven for baking, the number of the PCB entering the oven in the single baking process is increased, the baking efficiency is further improved, the thousand-layer rack is driven to be transferred by the baking vehicle, and the safety of the thousand-layer rack is improved.

Description

technical field [0001] The invention relates to the field of metal placement racks, in particular to a baking laminated rack for PCB circuit boards. Background technique [0002] The PCB board needs to be baked and dried after oiling in the final inspection process. In order to meet the needs of production and baking volume, the existing solder-resisting ovens are usually designed with upper and lower layers of brackets in the oven, and circuit boards or semi-finished circuit boards are inserted into the pig cage frame, with 20-25 boards / Each rack is placed on an oven rack for baking. Basically, each layer can be placed in 2 rows, and each row can be placed with 40 plates. From this, each cycle of each oven is calculated (heating time is about 20 minutes, baking time is 60 minutes, and cooling time is 20 minutes. minutes) can bake up to 80 boards, and the baked pig cage rack needs to be cooled to normal temperature before it can be taken out of the oven. Although the opera...

Problems solved by technology

In order to meet the needs of production and baking volume, the existing solder-resisting ovens are usually designed with upper and lower layers of brackets in the oven, and circuit boards or semi-finished circuit boards are inserted into the pig cage frame, with 20-25 boards / Each rack is placed on an oven rack for baking. Basically, each layer can be placed in 2 rows, and each row can be placed with 40 plates. From this, each cycle of each oven is calculated (heating time is about 20 minutes, baking time is 60 minutes, and cooling time is 20 minutes. minutes) can bake up to 80 boards, and the baked pig cage rack needs to be cooled to normal temperature before it can be taken out of the oven. Although the operator is equipped with high-temperature gloves, the operator may be caught Burn safety hazard

In addition, the baking efficiency of this baking frame structure is low, which cannot meet the production needs.
