Description

Technical Field

[0001] The invention relates to a device, in particular to a baking device. Background Art

[0002] Baking devices are common machines and equipment in the semiconductor industry, such as packaging. They are mainly used to heat and cure an electronic product to be processed, solidify it into shape, and remove bubbles in the electronic product. Curing applications include but are not limited to chip curing processing, die bonding curing processing, pre-baking, re-baking, flip chip curing, heat sink bonding curing, etc. The existing baking device includes an oven and a fan set at one end of the oven. The fan is used to drive the gas flow in the oven. When the fan fails, the oven door at the other end of the fan must be opened to remove the fan. Disassembly and maintenance are relatively inconvenient, so there is still room for improvement. Summary of the invention

[0003] The object of the present invention is to provide a baking device that can solve at least one of the above problems.

[0004] The baking device of the present invention comprises an oven and a fan unit, wherein the oven comprises an outer shell and an outer box body surrounding the outer shell, wherein an outer opening is formed at one end of the outer shell, and an outer box opening adjacent to the outer opening is formed at one end of the outer box body; the fan unit is arranged at one end of the oven and covers the outer box opening, and the fan unit comprises a wind wheel located in the outer shell, wherein the apertures of the outer opening and the outer box opening are both larger than the outer diameter of the wind wheel, so that the wind wheel can be taken out of the outer shell through the outer opening and the outer box opening.

[0005] In some implementations, the fan unit further includes a mounting base disposed at one end of the oven and shielding the opening of the outer box, a driving motor disposed on the mounting base, and a driving shaft connecting the driving motor and the wind wheel.

[0006] In some implementations, the fan unit further includes a first sealing member disposed between the outer box and the mounting seat.

[0007] In some implementations, the fan unit further includes a second seal disposed between the drive motor and the mounting base.

[0008] In some implementations, the fan unit further includes a shaft seal sleeved on the drive shaft and located between the mounting seat and the drive motor.

[0009] In some implementations, the fan unit further includes a mounting rod disposed on the mounting seat and extending toward the housing, and a first baffle plate penetrated by the mounting rod and abutting against the housing and shielding the outer opening.

[0010] In some embodiments, the oven further includes an inner shell surrounded by the outer shell, an inner opening adjacent to the outer opening is formed at one end of the inner shell, a diameter of the inner opening is larger than an outer diameter of the wind wheel, and the fan unit further includes a second baffle plate passed through by the mounting rod and abutting against the inner shell and shielding the inner opening.

[0011] In some implementations, the mounting base is fixed to the outer box by screwing.

[0012] The present invention has at least the following effects: since the diameters of the outer opening and the outer box opening are both larger than the outer diameter of the wind wheel, the wind wheel can be taken out from the outer casing through the outer opening and the outer box opening for maintenance or repair, which is quite convenient.

[0018] Before the present invention is described in detail, it should be noted that similar components are denoted by the same reference numerals in the following description.

[0019] See also Figure 1 and Figure 2 A first embodiment of a baking device of the present invention comprises an oven 1 , a fan unit 2 and a heater 3 .

[0020] The oven 1 includes an inner shell 11, an outer shell 12 surrounding the inner shell 11, and an outer box 13 surrounding the outer shell 12. An inner opening 111 is formed at one end of the inner shell 11 to define a heating space 112. An outer opening 121 adjacent to the inner opening 111 is formed at one end of the outer shell 12, and an outer box opening 131 adjacent to the outer opening 121 is formed at one end of the outer box 13. The heater 3 is disposed in the heating space 112 to heat the gas in the oven 1.

[0021] Matching reference Figure 3 and Figure 4 The fan unit 2 is disposed at one end of the oven 1 and covers the outer box opening 131. The fan unit 2 includes a mounting seat 20 disposed at one end of the oven 1 and covering the outer box opening 131, a driving motor 21 disposed on the mounting seat 20, a driving shaft 22 connected to the driving motor 21 and passing through the outer box opening 131, the outer opening 121 and the inner opening 111, a wind wheel 23 connected to the driving shaft 22 and located in the inner shell 11, a first sealing member 24 disposed between the outer box 13 and the mounting seat 20, and a first sealing member 24 disposed between the first sealing member 24 and the second sealing member 24. The second sealing member 25 between the driving motor 21 and the mounting seat 20, a shaft seal 26 set on the driving shaft 22 and located between the mounting seat 20 and the driving motor 21, four mounting rods 27 set on the mounting seat 20 and extending toward the outer shell 12, a first baffle 28 penetrated by the mounting rod 27 and abutting against the outer shell 12 and shielding the outer opening 121, and a second baffle 29 penetrated by the mounting rod 27 and abutting against the inner shell 11 and shielding the inner opening 111. Specifically, the mounting seat 20 is fixed to the outer box body 13 in a screw lock manner, but it is not limited thereto. The driving motor 21 is used to drive the driving shaft 22, so that the impeller 23 is driven by the driving shaft 22 to rotate, thereby causing the gas in the oven 1 to flow. The apertures of the inner opening 111, the outer opening 121 and the outer box opening 131 are all larger than the outer diameter of the impeller 23. Therefore, when the impeller 23 needs to be repaired, the oven 1 can be taken out directly through the inner opening 111, the outer opening 121 and the outer box opening 131 for maintenance.

[0022] The first seal 24 is made of rubber and is in the shape of a ring, and is used to prevent the gas inside the oven 1 from leaking outward from between the outer box opening 131 and the mounting seat 20. The second seal 25 is also made of rubber and is in the shape of a ring, and is used to further prevent the gas inside the oven 1 from leaking outward from between the drive motor 21 and the mounting seat 20. The shaft seal 26 is in the shape of a ring, and is used to prevent impurities or dirt inside the oven 1 from entering the drive motor 21. The first baffle 28 is in the shape of a ring and is screwed onto the mounting rod 27, and is used to block most of the airflow inside the oven 1 from flowing outward. The second baffle 29 is in the shape of a ring and is screwed onto the mounting rod 27, and is also used to block most of the airflow inside the oven 1 from flowing outward. It should be noted that the number of the mounting rods 27 is not limited to four, and in other embodiments, it may be only one.

[0023] In summary, the baking device of the present invention has the inner opening 111, the outer opening 121 and the outer box opening 131 having apertures larger than the outer diameter of the wind wheel 23, so that the wind wheel 23 can be taken out from the outer shell 12 through the outer opening 121 and the outer box opening 131 for maintenance or repair, which is quite convenient, and can indeed achieve the purpose of the present invention.

[0024] The above are merely embodiments of the present invention and should not be used to limit the scope of the present invention. All simple equivalent changes and modifications made according to the claims and description of the present invention are still within the scope of the present invention.
