Preferably, the jig further comprises a first heating block, and the first heating block is fixed to the first heating plate to heat the first heating plate.

Preferably, the at least one mechanical arm further comprises an adsorption portion, and the adsorption portion adsorbs the circuit board by using a vacuum principle to move the circuit board in a first direction.

Preferably, the first direction is perpendicular to the first heating plate.

Preferably, the workbench includes a second heating block, and the second heating block is fixed to the second heating plate to heat the second heating plate.

Preferably, the preheating device further comprises a cooling structure, and the cooling structure is a fan to cool the circuit board.

Compared with the prior art, the beneficial effect of the present invention is that the heating structure of the pre-heating device of the present invention heats the circuit board by the first heating plate and the second heating plate by the mechanical arm sucking the circuit board, and the circuit board is cooled by the cooling structure. The board can be repeatedly heated and cooled repeatedly at one station to make the test reliable.

In summary, this creation is not only innovative in terms of space type, but also can enhance the above-mentioned multiple functions compared with the customary items. It should fully comply with the statutory invention patent requirements of novelty and progressiveness, and apply for it according to law. Approving this new type of invention patent application, in order to invent invention, to the sense of virtue.

The spirit of the present invention will be described in the following drawings and detailed description, and those skilled in the art will be able to change and modify the technology disclosed by the present invention after the preferred embodiment of the present invention. The spirit and scope of this creation.

The terms “first”, “second”, etc. used in this document are not specifically intended to refer to the order or order, nor are they used to limit the case. They are only used to distinguish between components or operations described in the same technical terms. .

The terms used in this document, unless otherwise specified, generally have the usual meaning of each term used in the art, in the context of the disclosure, and in the particular content. Certain terms used to describe the disclosure are discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in the description of the disclosure.

Referring to FIG. 1 , a preheating device 100 is used for repeatedly heating and cooling a circuit board 200 . The preheating device 100 includes a cooling structure 10 and a heating structure 20 . In an embodiment, the refrigeration structure 10 is a fan.

The heating structure 20 includes a jig 22 and a table 24. The jig 22 includes a mounting table 220, a plurality of robot arms 222 fixed to the mounting table 220, a first heating plate 224, and a first heating block 226 fixed to the first heating plate 224. Each robot arm 222 is movably mounted to the first heating plate 224. Each robot arm 222 includes a suction portion 2220. Multiple robots The arms 222 are parallel to each other. Each robot arm 222 is generally perpendicular to the first heating plate 224. In an embodiment, the first heating plate 224 is made of aluminum.

The table 24 includes a second heating plate 240 and a second heating block 242 fixed to the second heating plate 240. The second heating plate 240 is substantially parallel to the first heating plate 224. In an embodiment, the second heating plate 240 is made of aluminum.

Please refer to FIG. 2 to FIG. 6. When the preheating device is used, the following steps are included: Step 1: Place the circuit board 200 on the worktable 24; Step 2. Move the mechanical arm 222 toward the first direction relative to the first heating plate 224. In order to grasp the circuit board 200; in step 3, the first heating plate 224 generates heat, and the mechanical arm 222 moves relative to the first heating plate 224 in a second direction opposite to the first direction until the side of the circuit board 200 and the first heating plate 224 In the fourth step, the second heating plate 240 generates heat and moves in the second direction relative to the first heating plate 224 until it interferes with the other side of the circuit board 200. At this time, the two sides of the circuit board 200 are heated by the first heating plate 224 and the second heating plate 224. The plate 240 is heated; in step 5, the first heating plate 224 and the second heating plate 240 stop heating, and the second heating plate 240 moves back to the original position in the first direction; in step 6, the mechanical arm 222 faces the first heating plate 224 Moving in one direction causes the circuit board 200 to float, and the cooling structure 10 cools the circuit board 200. By repeating the above steps, the circuit board 200 can be repeatedly heated and cooled to meet the requirements before testing.

In summary, this creation is not only innovative in terms of technical thinking, but also has many of the above-mentioned functions that are not in the traditional methods of the past. It has fully complied with the statutory invention patent requirements of novelty and progressiveness, and applied for it according to law. The bureau approved this new type of invention patent application, in order to invent invention, to the sense of virtue.
