Baking device capable of preventing objects from falling

Technical Field

The present invention relates to a structure technology of a baking device body, particularly to a baking device capable of preventing objects from falling.

Background

As is known, a baking apparatus is an apparatus for heating an object, and is generally applied to heating operations of photoelectric products or components thereof, such as PCBs, LCDs, Touch panels (Touch panels), and the like, and can perform drying, aging test, and other treatments on the photoelectric products or the components thereof.

Most of the conventional toasting devices comprise a box body, which is formed with a heating chamber for accommodating the object to be heated and heating therein, and a heating element (such as an electric heating tube), a blower, an air inlet pipe, an air outlet pipe, etc. disposed around the heating chamber, so as to form heat convection for drying or aging the object to be heated.

In the heating chamber of the baking device, a support frame is usually placed or fixed, and the support frame is used to support the object to be heated, so that the object to be heated can be stably placed in the heating chamber to be heated. However, in the operation process of the box body of the baking device, the box body is mostly influenced by the vibration frequency generated by the running of an internal blower or a motor, or the circulation flow of hot air and other factors, so that the box body can generate micro vibration under the conduction action of the vibration frequency; moreover, since the rack is usually placed or fixed on the inner wall of the heating chamber, the micro-vibration of the box body is also transmitted to the rack, so that the object placed on the rack is easily displaced due to the vibration of the rack, even the object falls off the rack, and the yield of the object being baked is affected.

In order to improve the above problem, manufacturers have mounted the blower or the motor at a position away from the casing to reduce the influence of the vibration frequency transmission generated when the blower or the motor is operated on the casing. However, this method not only increases the complexity of the structure of the hot air channel connected to the blower at the periphery of the box and the heating chamber, but also has a very limited effect of reducing the vibration of the box, so how to avoid the vibration of the box from being transmitted to the supporting frame becomes a technical subject to be overcome.

Disclosure of Invention

In view of the above, the present invention is directed to prevent the vibration of the box from being transmitted to the supporting frame, so as to improve the problem that the object placed on the supporting frame falls off due to the vibration of the supporting frame.

In order to solve the above problems, the present invention provides a baking apparatus capable of preventing objects from falling, comprising:

wherein, the periphery of the bearing frame is not contacted with the inner wall of the heating chamber and the box body of the oven.

In a further embodiment, the bottom of the heating chamber is formed with at least one aperture providing for the shelf to extend outside the oven housing.

In further implementation, at least one supporting leg is arranged at the end part of the supporting frame penetrating to the outside of the oven body, the supporting frame is used for adjusting the height of the supporting frame, the supporting frame penetrates through the supporting leg and penetrates through the through hole to be vertically arranged on the ground, and the number of the supporting leg and the number of the through hole are equal.

In a further implementation, the supporting frame comprises a plurality of beams which are arranged at intervals in a preset direction, a plurality of inclined spanning rods which are adjacent in pairs and used for placing the objects are respectively arranged on the plurality of beams, a supporting surface for placing the objects is constructed between each two adjacent inclined spanning rods, and the supporting surface is parallel to the preset direction. Wherein the predetermined direction is collinear with a diagonal line that forms an oblique angle with respect to a horizontal line of the ground. A cross rod is assembled on the plurality of cross beams, a plurality of retaining columns are arranged on the cross rod, and the retaining columns are located on one end edge of the bearing surface. The bumping post has an oblique taper. The inclined cross rod is provided with a sawtooth-shaped groove. The groove is parallel to the predetermined direction.

According to the technical means, the technical effects of the invention are as follows: by means of the characteristic that the periphery of the bearing frame is prevented from contacting with the inner wall of the heating chamber and the box body of the oven, the vibration of the box body can be effectively prevented from being transmitted to the bearing frame, and then the stability of the object placed on the bearing frame for baking is improved, so that the problem that the object is easy to fall off from the bearing frame is solved.
