Description

A kind of circuit board baking inner bag

Technical field

The utility model relates to circuit board baking, particularly a kind of circuit board baking inner bag.

Background technology

Circuit board, is important electronic unit, is the supporter of electronic devices and components. In circuit board process, conventionally need to toast circuit board, so that the stress of substrate is fully lax, thereby reduce the buckling deformation of substrate in processing procedure.

Current circuit board toasts the baking box adopting and comprises a main box, in main box, be provided with an inner bag, circuit board is placed in inner bag, and then pass into hot blast and toast, in the time that circuit board is toasted, but circuit board is after being baked, its inner bag adopts ironwork more, its heat-conducting effect is good, and therefore, the temperature of inner bag is higher, but operating personnel are in the time taking the circuit board having dried, very easily cause operating personnel's arm or palm to touch inner bag, thereby cause burning of operating personnel's arm or palm, cause unnecessary potential safety hazard.

Utility model content

The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of simple in structure, the easy to operate and circuit board baking inner bag that can avoid operating personnel to burn is provided.

The purpose of this utility model is achieved through the following technical solutions: a kind of circuit board baking inner bag, it comprises the inner bag body that is casing, the front end face of described inner bag body opens wide, and all offer multiple air admission holes on the upper and lower, left and right sidewall of inner bag body, in described inner bag body, be provided with multiple demarcation strips that be arranged in parallel, on described demarcation strip, offer multiple breach, dismountable oven dry plate that is provided with in described breach, and be provided with leader on the front end face of drying plate.

On described breach, offer slot, the both sides of drying plate are provided with the projection coordinating with slot, and described projection is slidably installed in slot.

The middle part of described oven dry plate is provided with screen cloth.

The rearward end of described breach is provided with an electromagnet, is provided with in the rearward end of drying plate the iron block of inhaling mutually with electromagnet.

Described demarcation strip is three.

The utlity model has following advantage: circuit board baking inner bag of the present utility model, be provided with multiple demarcation strips, in demarcation strip, by being combined with between slot and projection, oven dry plate is detachably installed, on oven dry plate, be provided with not transcalent handle, thereby after circuit board is dried, operating personnel hold handle, just can say that drying plate takes out inner bag, and then the circuit board after drying is well taken out, can avoid operating personnel to contact with inner bag high-temperature component, thereby avoid operating personnel to be burnt, improved staff's security.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is further described, protection domain of the present utility model is not limited to the following stated:

As shown in Fig. 1 ~ Fig. 3, a kind of circuit board baking inner bag, it comprises the inner bag body 1 that is casing, the front end face of described inner bag body 1 opens wide, and on the upper and lower, left and right sidewall of inner bag body 1, all offer multiple air admission holes 2, in described inner bag body 1, be provided with multiple demarcation strips that be arranged in parallel 3, in the present embodiment, described demarcation strip 3 is three. On described demarcation strip 3, offer multiple breach 4, the interior dismountable oven dry plate 5 that is provided with of described breach 4, and on the front end face of drying plate 5, be provided with leader 6, described handle 6 is made for athermanous material, as pottery, heat-protecting glass, open-textured woodwork are made.

In the present embodiment, on described breach 4, offer slot 7, the both sides of drying plate 5 are provided with the projection 8 coordinating with slot 7, described projection 8 is slidably installed in slot 7, when installation, projection 8 is inserted in slot 7, just can be dried plate 5 and be installed togather with demarcation strip 3.

Further, the middle part of described oven dry plate 5 is provided with screen cloth 9, in the present embodiment, screen cloth adopts irony screen cloth, has certain rigidity, can bear polylith circuit board, screen cloth 9 can have the effect of ventilating air, thereby can make upper strata cavity in inner bag body 1 be communicated with lower floor cavity, thereby makes can form fast heat exchange in inner bag body 1, thereby ensure the even of inner bag body 1 interior temperature, thereby improve the quality of circuit board baking.

In the present embodiment, the rearward end of described breach 4 is provided with an electromagnet, is provided with in the rearward end of drying plate 5 iron block of inhaling mutually with electromagnet, is inserted into behind the bottom of slot 7 drying plate 5, electromagnet is switched on, just can make to dry plate 5 and be fixed together with demarcation strip 3, avoid the transport of convenient for firing case, in the time that needs take out, electromagnet is carried out to power-off, operating personnel hold handle 6, just can take out drying plate 5 easily, thereby be convenient to picking and placeing of circuit board.

The course of work of the present utility model is as follows: circuit board is placed on and is dried on plate 5, then oven dry plate 5 is coordinated and put in place with slot 7, and making electromagnet energising, hot blast enters in inner bag body 1 in air admission hole 2, and circuit board is toasted, after baking, electromagnet power-off, operating personnel hold handle 6, will dry plate 5 and take out, and then the circuit board of drying on plate 5 is taken out, and then carry out the baking of next group circuit board.
