Description
Technical field
The present invention relates to a kind of temperature control box, relate in particular to a kind of employed temperature control box of electronic package roasting procedure that is used for.
Background technology
Present domestic electronic package roasting plant adopts steam or electrically heated hot air circulation temperature control box more.The most traditional temperature control box that is used for electronic package, as shown in Figure 1, be provided with blower fan 1 in 4 tops, temperature control box operating room, the outlet of blower fan 1 is downwards towards well heater 2, well heater 2 opposite sides lead to operating room 4, operating room 4 is provided with the Sheng dish 5 multilayer through hole, that be used for the electronic component of Sheng Zaixu baking encapsulation, and the middle position of each Sheng dish 5 is provided with temperature sensor, is provided with the temperature controller 3 of accepting sensor signal control heater unlatching then, closing in temperature control box top.The temperature control box of this structure causes in the operating room temperature difference bigger because the scattered distribution of its heating and hot blast is owed rationally, and generally the temperature difference is 5 ℃-20 ℃ and does not wait, so can not satisfy the production requirement of electronic component; Temperature controller is arranged on temperature control box top in addition, is subjected to the influence of temperature control box thermal source, and aging easily reaching influences temperature-controlled precision.In addition, thermal current is stopped, cause the temperature in the temperature control box extremely inhomogeneous owing to contain the pallet of live sub-element multilayer in the temperature control box operating room.The electronic component temperature difference in operating room's diverse location during baking is very big, the phenomenon of local overheating or local overcooling can occur.Even often open the temperature control chamber door artificially, at high temperature repeatedly turn over and change pallet, but the electronic component of baking still exists quality nonconforming, even the problem of scrapping by the gross, and labour intensity is big, and the thermal efficiency is low.
In the later stage, application number is 87201262 flow-guiding type hot-air oven, has done improvement to a certain degree, has obtained certain producing effects, but because its vertically highly too big effect still is not very desirable, still has the bigger defective of the temperature difference, and the temperature difference is about 8 ℃.And in the hot air circulation process, influenced the temperature stability in the operating room, influenced the quality of the baking-curing of electronic component, produced in enormous quantities especially now, problem is just even more serious, has directly reduced the yield rate of producing.
Summary of the invention
Technical matters to be solved by this invention is that a kind of a kind of electronic package temperature control box that improves present product deficiency is provided.
The technical scheme that the present invention solve the technical problem is, a kind of electronic package temperature control box, comprise casing, blower fan, change the air port, well heater, exhausr port, casing is provided with the operating room and opens door, place the temperature sensor of operating room's enteroception temperature, accept temperature sensor signal and control the heating element unlatching, the temperature controller of closing, multilayer is set in order to place the pallet of electronic component in the operating room, it is characterized in that: described well heater is located at the below, operating room, the air outlet of blower fan is towards well heater, the well heater opposite side leads to a casing left side respectively, the air inlet duct of establishing in the right wall, the air inlet duct other end is communicated with the operating room, and the inlet scoop of blower fan is communicated with operating room's inner bottom part; 2 row about described multilayer pallet is divided into respectively by operating room's one sidewall, leave passage between row and the row; Air vent is not offered in described tray bottom; Described operating room sidewall is provided with the ventilating opening that is communicated with air inlet duct, and described ventilating opening correspondence is arranged between pallet layer and the layer.Temperature control box after the improvement is scientific and reasonable for structure with it, has a narrow range of temperature, and operating room's bulk temperature is even, and stable performance and satisfy the high quality requirements of baking-curing of all kinds of electronic element products.
In the present invention:
The big I of ventilating opening area of operating room's sidewall increases progressively from the bottom to top.Be consistent to adapt to hydromechanical principle, to make the hot blast rate that enters into each pallet layer, to improve the homogeneity of each layer temperature.
Described fan shaft is a hollow, and an end is communicated with the inlet scoop of blower fan, and the other end is communicated with as scavenge port and temperature control box are extraneous.So design, ingeniously utilized the formed negative pressure in blower fan inlet scoop that fresh air outside is automatically sucked and the very first time blows to heating element and promotes and be delivered to the operating room after the temperature and change fresh air, prevent that cold air from directly to operating room's Temperature Influence, having improved the stability of operating room's temperature.In addition, also to motor shaft and on every side annex implemented good air cooling effect, improved the life-span of blower fan greatly.
In order to prevent that temperature controller is subjected to the influence of temperature control box thermal source, temperature controller is located at the below, operating room, guaranteed the condition of work of temperature controller, improve temperature controller control accuracy and permanance.
In order to make the more even circulation of hot blast, the inlet scoop of blower fan is communicated with operating room inner bottom part central authorities, and is provided with volume adjusting apparatus, to regulate the size of hot blast rate in the blower fan inlet scoop.
For the needs of discharging waste gas in the temperature control box and dealing with burst reduce the situation of temperature, be provided with Forced discharge fan at described exhausr port.This design also can need not be opened the door at temperature-fall period, can realize at the uniform velocity cooling by control, has avoided bigger the fluctuating of temperature, can guarantee the electronic product production of high-quality requirement, the especially high-precision requirement of production.
Be provided with two insulation layers on described casing, internal layer is the soak layer, and skin is the low temperature heat-insulation layer, has more guaranteed the stability of work indoor temperature, has stoped heat abstraction, has reduced energy consumption.
For regulating thermal current direction and speed, to improve operating room's internal temperature consistance; In the gas dispersion net of top, inlet scoop area coverage greater than the band through hole of inlet scoop area.
