Description

Baking device capable of preventing objects from falling

The invention relates to the structure technology of the baking device body, in particular to a baking device capable of preventing the object from falling.

It is known that a baking device is a device for heating an object. For example, an industrial oven is generally applied to a heating operation of an optoelectronic product such as a PCB, an LCD or a Touch Panel or a component thereof, and can be used for the above photoelectric product or The components are subjected to drying or aging tests.

The conventional baking device mostly comprises a box body having a heating chamber capable of accommodating the object to be heated and being heated, and a heating element (such as an electric heating tube) disposed on the periphery of the heating chamber, a blower, and an intake and exhaust pipe. Etc., the air in the heating chamber can be thermally convected to dry or age the object to be heated.

In the heating chamber of the baking device, a rack is usually placed or fixed, and the rack is used to hold the object to be heated, so that the object to be heated can be placed in the heating chamber to be heated. However, since the cabinet of the baking device is in operation, the atmosphere is affected by the vibration frequency generated by the blower or motor running inside, or the circulation of the hot air, so that the box is subjected to the vibration frequency transmission. The micro-vibration is generated; and it is known that since the carrier is usually placed or fixed on the inner wall of the heating chamber, the micro-vibration of the box is also transmitted to the frame, which makes the object placed on the frame extremely easy to cause The frame is vibrated and displaced, even the phenomenon that the object falls from the frame, which affects the yield of the object to be baked.

In order to improve the above problems, the manufacturer assembles the blower or the motor to a position away from the casing to reduce the influence of the vibration conduction generated when the casing is operated by the blower or the motor. However, this method not only increases the structural complexity of the hot air flow path connected to the air blower in the periphery of the box body and the heating chamber, but also has a very limited effect of reducing the vibration of the box body. Therefore, how to avoid the vibration conduction of the box body to On the shelf, it has become a technical issue to be overcome.

In view of the above, the object of the present invention is to prevent the vibration of the box from being transmitted to the frame, thereby improving the problem that the object placed on the frame falls due to the vibration of the frame.

In order to solve the above problems, the present invention provides a baking device capable of preventing an object from falling, comprising: an oven standing on the ground, the inside of the oven having a heating chamber; and a rack housed in the heating chamber. One end of the frame extends to the outside of the oven and stands on the ground; wherein the periphery of the frame is removed from the inner wall of the heating chamber and the oven body.

In a further implementation, the bottom of the heating chamber is formed with at least one perforation that provides the carrier to the outside of the oven.

In a further implementation, the end of the frame that extends outside the casing of the oven is provided with at least one support leg for adjusting the height of the frame, and the frame is placed on the ground through the through-hole through the support leg. And the number of the support legs and the perforations are equal.

In a further implementation, the rack comprises a plurality of beams arranged at a distance in a specific direction, and the plurality of beams are respectively provided with a plurality of diagonally spanning rods which are arranged adjacent to each other to provide objects, two to two Adjacent diagonal spans are constructed to form a bearing surface for the object to be placed, the bearing surface being parallel to a particular direction. Wherein the particular direction is collinear with a diagonal line that forms an oblique angle with respect to the horizontal line of the ground. A plurality of crossbars are disposed on the plurality of cross beams, and the crossbars are provided with a plurality of retaining posts, and the retaining poles are located at one end of the supporting surface. The brace has an oblique vertebra. A zigzag groove is formed in the diagonal span. The The grooves are parallel to a particular direction.

According to the above technical means, the technical effect that can be produced by the invention is that the vibration of the box body can be effectively prevented from being transmitted to the rack by virtue of the characteristics of the inner wall of the heating chamber and the oven body being removed from the periphery of the rack, thereby improving The object is placed on the shelf to receive the stability during baking to overcome the problem that the object is easy to fall off the shelf.
