Description:
BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The disclosure relates to oven apparatuses, and particularly to an oven apparatus that can be used for curing and/or heating coatings on a housing of an electronic device. 
         [0003]    2. Description of Related Art 
         [0004]    An electronic device housing can have coatings formed on its external surfaces. The coatings may be Polyurethane (PU) inks and Ultraviolet (UV) inks that are cured or solidified to create an upgraded aesthetic appearance. During the curing or solidifying process, a PU oven apparatus and a UV oven can solidify the PU inks and the UV inks by heating and curing with Ultraviolet light, respectively. 
         [0005]    The PU oven and the UV oven are arranged in a line. A conveyor belt carries the housing between the PU oven and the UV oven. However, this arrangement may occupy a large space. 
         [0006]    Therefore, there is room for improvement within the art.

The periphery boards  14  and the frame  12  cooperatively enclose a first chamber  322  and a second chamber  49  under the first chamber  322 . 
         [0017]    The air drafting module  20  can adjust the working temperature of the curing module  30 . The air drafting module  20  includes an assembling board  22 , an air drafter  24 , an adjusting valve  26  and an air-inlet port  28 . The assembling board  22  has the air drafter  24 , the adjusting valve  26  and the air-inlet port  28  assembled thereon. The assembling board  22  assembles in the upper frame section  122  of the frame  12 . The air drafter  24  includes a driving unit  242 , an outlet  244 , and a plurality of air pipes (not shown) below the assembling board  22 . The air pipes communicate with the adjusting valve  26  and the outlet  244 . The driving unit  242  drafts air from the first chamber  322  and expels the air through the air pipes and the outlet  244  to outside. The adjusting valve  26  includes a valve case  262 , a plurality of knobs  264 , and a plurality of guiding pipes  266 . The valve case  262  connects the air pipes and the guiding pipes  266 . The knobs  264  are mounted on the guiding pipes  266 . The guiding pipes  266  extend to the first chamber  322  and are adjacent to the curing module  30 . The air-inlet port  28  defines a through hole (not labeled) through the assembling board  22 . The air-inlet port  28  includes a filtering plate  282  detachably covering the through hole. The filtering plate  282  is positioned on the assembling board  22  and filters the air entering into the first chamber  322 , and the air can be absorbed into the guiding pipes  266 . 
         [0018]    Referring further to  FIG. 3 , the curing module  30  can cure UV coated housings. The curing module  30  includes a supporting plate  32 , two gearing mechanisms  34 , and a plurality of UV lamp assemblies  36 . The supporting plate  32  supports the two gearing mechanisms  34  and the UV lamp assemblies  36 . The supporting plate  32  assembles on the middle frame section  124 . Accordingly, the supporting plate  32 , the assembling board  22  and the periphery boards  14  cooperatively enclose the first chamber  322 . The supporting plate  32  defines a slot  324  and a recess  326  at the corner. The slot  324  runs though the supporting plate  32  and interconnects the second chamber  49  to guide the transportation of the transporting module  50 . A shield  328  covers the slot  324  and prevents dust from entering the slot  324 , the recess  326  has a sidewall  3262  at an end thereof, the sidewall  3262  defines a hole (not labeled) interconnecting with the second chamber  49  to guide transportation of the transporting module  50 . The two gearing mechanisms  34  are positioned adjacent to two sides of the supporting plate  32 . Each gearing mechanism  34  includes two gear wheels  342  arranged on the supporting plate  32 , a motor  344  connecting one gear wheel  342 , and a chain  346  mating with the two gear wheels  342  and driven by the motor  344 . The gear wheel  342  engages with the transporting module  50 . Therefore, the motor  344  can drive the transporting module  50 . The UV lamp assemblies  36  are spaced positioned on the supporting plate  32  and form a curing passage  360  for the passage of the transporting module  50 . Each UV lamp assembly  36  includes a supporting frame  362  and a UV lamp  364  assembled in the supporting frame  362 , the supporting frame  362  secures the guiding pipes  266  (not shown in  FIG. 3 ), and air adjacent to the UV lamp  364  is guided by and absorbed by the guiding pipe  266  to cool the UV lamp  364 . 
         [0019]    Referring to  FIGS. 4 and 6 , the heating module  40  can heat the housing having a UV coating. The heating module  40  includes a box  42 , a blowing unit  44 , heating coils  46  and two windshield boards  48 . The box  42  is a hollow body and defines two opposite openings  422 . The blowing unit  44  and the heating coils  46  are assembled into the box  42 . The blowing unit  44  blows hot air when the heating coils  46  are heated. Referring further to  FIG. 5 , the windshield board  48  includes an airproof peripheral wall  482  and a venting internal wall  484  parallel to the peripheral wall  482 . The internal wall  484  defines a plurality of through apertures  4842 . The box  42  can be assembled on the bottom frame section  126  of the frame  12 , the windshield boards  48  are fixed at the sides of the frame  12 , and each windshield board  48  interconnects openings  422  of the box  42 . The periphery boards  14  (not shown on  FIGS. 4 and 5 ) are arranged at the other opposite sides of the frame  12 , enclosing the second chamber  49 . The second chamber  49  accommodates part of the transporting module  50  (not shown in  FIGS. 5 and 6 ). Accordingly, the inside space of the box  42 , the insides space of the windshield boards  48  and the second chamber  49  communicate to define a gas path  490 . 
         [0020]    Referring back to  FIGS. 2 and 3 , the transporting module  50  includes a plurality of driving wheels  52  and a conveyor belt  54 . The driving wheels  52  are assembled on the extending plate  16 , the supporting plate  32  and the frame  12 . The conveyor belt  54  is wrapped around the driving wheels  52  and engages with the gearing mechanisms  34 , accordingly, the conveyor belt  54  can be driven by the gearing mechanisms  34  to rotate. The conveyor belt  54  can run inside and between the first chamber  322  and the second chamber  49 . 
         [0021]    During assembly of the oven apparatus  100 , the heating module  40  is assembled to the frame  12 . The blowing unit  44  and the heating coils  46  are positioned into the box  42  and the box  42  is placed onto the bottom frame section  126  of the frame  12 . The supporting plate  32  of the curing module  30  is secured to the middle frame section  124  of the frame  12 , and the assembling board  22  of the air drafting module  20  is placed on the first wall  122 . The conveyor belt  54  is mounted to the driving wheels  52 . The periphery boards  14  and the two windshield boards  48  are respectively assembled to the frame  12  and enclose the first chamber  322  and the second chamber  49 . Therefore, the oven apparatus  100  is assembled. 
         [0022]    In use, the housing having UV coatings and PV coatings is positioned on the conveyor belt  54 . The curing module  30  is started, and the gearing mechanism  34  drives the conveyor belt  54  to rotate. Meanwhile, the UV lamp assemblies  36  turn on for curing the UV coatings of the housing. The air drafting module  20  is started to control the curing intensity of the UV lamp assemblies  36 . The air is drafted by the air drafter  24  and enters into the first chamber  322  through the air-inlet port  28 , the air is expelled to outside through the guiding pipes of the adjusting valve  26 , the air pipes and the outlet  244 . Because the guiding pipes can be adjusted by the knobs  264  to cool the UV lamp  364 , the curing intensity of the UV lamp assemblies  36  can be adjusted by the knobs  264 . When the housing is transported into the second chamber  49  by the conveyor belt  54 , the heating module  50  heats and solidifies the PU coatings. The heating coils  46  are heated, and the blowing unit  44  blows hot air from the heating coils  46  into the second chamber  49 . Thus, the housing heats in the second chamber  49  and then transports out of the oven apparatus  100  by the conveyor belt  54 .
