Abstract
Description
Technical Field
[0001] This utility model relates to the field of tunnel oven baking plates, and in particular to a vertical baking plate rack. Background Technology
[0002] In typical PCB factories, copper-clad laminates (CCLs) need to be baked after cutting to reduce moisture content, minimize board expansion and contraction, and improve production precision. Current baking methods involve stacking the cut CCLs in a vertical oven and baking them at 150 degrees Celsius for more than 4 hours. This method has a long baking time and consumes a lot of electricity. The temperature in the middle of the stacked boards is uneven, resulting in inconsistent water absorption rates. Furthermore, the boards are easily scratched and scrapped during handling, leading to cost losses. Summary of the Invention
[0003] To solve the above problems, this technical solution provides a vertical baking tray rack.
[0004] To achieve the above objectives, the technical solution is as follows:
[0005] A vertical baking rack includes several bases arranged side by side, the outermost base having a sliding groove, and also includes multiple partitions for isolating vertical circuit boards, the partitions having sliders that cooperate with the sliding grooves.
[0006] In some embodiments, the partition has multiple baffles inside.
[0007] In some embodiments, the end face of the base is provided with a plurality of heat transfer holes.
[0008] In some embodiments, the outermost base has a plurality of locking holes in the lateral direction.
[0009] In some embodiments, the outermost base is provided with a limiting portion for limiting the slider.
[0010] In some embodiments, the base is further provided with a connecting portion, and the connecting portion is provided with a plurality of heat transfer through holes.
[0011] The beneficial effects of this application are:
[0012] This application features multiple partitions, each of which moves via a slider and a groove, thereby altering the spacing between adjacent partitions. This allows for the vertical placement of copper-clad laminates of different specifications for baking. The vertical arrangement of the boards improves ventilation and baking efficiency, reducing baking time and costs. Furthermore, it minimizes scrap losses caused by scratches and copper surface dents from stacked boards, improving first-pass yield. Finally, the boards are heated evenly, effectively reducing overall expansion and contraction and increasing production precision. Attached Figure Description
[0013] To more clearly illustrate the technical solutions in the embodiments of this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below.
[0014] Figure 1 This is a schematic diagram of the structure of an embodiment of the present utility model. Figure 1 ;

[0016] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0017] Please refer to Figure 1-2 As shown, a vertical baking rack includes several bases 1 arranged side by side, the outermost base 1 is provided with a sliding groove 2, and also includes multiple partitions 3 for isolating vertical circuit boards, the partitions 3 being provided with sliders 4 that cooperate with the sliding grooves 2.
[0018] This application features multiple partitions, each of which moves via a slider and a groove, thereby altering the spacing between adjacent partitions. This allows for the vertical placement of copper-clad laminates of different specifications for baking. The vertical arrangement of the boards improves ventilation and baking efficiency, reducing baking time and costs. Furthermore, it minimizes scrap losses caused by scratches and copper surface dents from stacked boards, improving first-pass yield. Finally, the boards are heated evenly, effectively reducing overall expansion and contraction and increasing production precision.
[0019] In this embodiment, the partition 3 is provided with multiple baffles 5 inside. The baffles are arranged at intervals to block the board. In addition, the gaps can be used for ventilation and heat conduction to avoid uneven heating.
[0020] In this embodiment, the end face of the base 1 is provided with a plurality of heat transfer holes 6, and the bottom can also be ventilated and conduct heat.
[0021] In this embodiment, the outermost base 1 is provided with multiple locking holes 7 in the lateral direction. When the partition is moved to a suitable position, it is fixed by screws passing through the locking holes and the slider, thereby making the partition adjustable.
[0022] In this embodiment, the outermost base 1 is provided with a limiting part 8 for limiting the slider 4 to prevent the partition from falling off.
[0023] In this embodiment, the base 1 is also provided with a connecting part 9, and the connecting part 9 is provided with a plurality of heat transfer holes 6, and the bottom can also be ventilated and conduct heat.
[0024] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
