Background
In the production process of printed circuit boards, trays for carrying and transporting the printed circuit boards are typically provided with a peripheral main frame and support bars of different forms for supporting and spacing the plurality of printed circuit boards. The Printed Circuit Board (PCB) carrier (tray) is used for storing and transporting the PCB during the module manufacturing process, and also enables the PCB substrates to be accurately arranged during the assembly process of the PCB substrates, thereby improving the assembly yield. Therefore, the PCB substrate supporting structure should have high reliability, i.e. the structure should be stable, firm, not easy to deform, and able to precisely arrange the plurality of PCBs. In addition, the PCB substrate carrying structure also requires a high degree of freedom to enable carrying of PCBs of different sizes, and other considerations such as selection of low cost materials and ease of fabrication are also contemplated.
The conventional tray is used for carrying a PCB substrate and mainly comprises a main frame and a plurality of support rods. The inner space formed by the main frame is divided into two parts by a clapboard parallel to the support rod to form two opposite L-shaped areas. The support rods in each region are arranged at equal intervals and used for bearing and separating a plurality of substrates. The tray is typically made by resin injection molding or injection molding. The material for manufacturing the tray is easy to deform, the parallel precision between the support rods is insufficient, and the assembly qualification rate (assembly yield) is reduced. In addition, the tray can only bear one size of PCB substrate, when the size is changed, another tray needs to be customized again, the manufacturing time is long, the original tray can not be used and discarded, the tray is not suitable for diversified product mass production, and the cost is wasted. As mentioned above, there is a need to provide a PCB substrate supporting structure, which can overcome the above-mentioned disadvantages.
Therefore, how to solve the above problems and deficiencies of the prior art is the subject of the urgent research and development of the related art.

Detailed Description
In order to solve the problem of the cost of the conventional printed circuit board substrate, the inventor of the present invention has made many years of research and development to overcome the disadvantages of the conventional products, and will hereinafter describe in detail how to provide a structure for supporting a printed circuit board substrate according to the present invention to achieve the most efficient functional requirements. In order to make the aforementioned and other objects, features, and advantages of the invention more apparent, preferred embodiments of the invention are described in detail below with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is an exploded schematic view of a supporting structure of a printed circuit board substrate according to the present invention. Fig. 2 is a combination schematic view of the printed circuit board substrate bearing structure of the invention. The pcb substrate supporting structure 100 according to the embodiment of the invention has a low cost and a short manufacturing time, thereby reducing and shortening the cost and preparation time of the product manufacturing tool. In detail, the pcb substrate supporting structure 100 includes a main frame 110, a grid 120, at least one positioning seat 130 and at least one fixing member 140.

The main frame 110 includes at least one limiting member 112, at least one positioning hole 114 and at least one fixing hole 116, the fixing holes 116 are located at four corners of the main frame 110, the positioning holes 114 are located at two opposite sides (each side has two positioning holes 114) of the main frame 110, the limiting members 112 are disposed at four peripheral side surfaces of the main frame 110, each peripheral side surface has two limiting members 112, wherein the limiting members 112 are combined on the main frame 110 through the limiting holes 1121.
The grid 120 is in a criss-cross matrix shape and has a plurality of grids, the grid 120 is used for bearing printed circuit boards with different sizes, the grid 120 is made of heat-resistant structural materials, wherein the grid 120 is made of materials with high heat conductivity coefficient, so that the grid 120 can uniformly conduct heat energy or heat to the whole grid 120 in the baking process, and further the printed circuit boards can be uniformly heated. It should be noted that each grid size of the grid 120 is smaller than the size of the printed circuit board, so as to prevent the printed circuit board from falling from the grid. The positioning base 130 is disposed on the main frame 110 by being pivoted to the positioning hole 114, wherein the positioning base 130 includes a cover plate 132 and a positioning post 134, and is pivoted to the positioning hole 114 by the cover plate 132 and the positioning post 134. The fixing member 140 fixes the grill 120 to the main frame 110 by pivotally connecting the at least one fixing hole 116. In an embodiment, the pcb substrate supporting structure 100 further includes a plurality of teflon tubes 122, the teflon tubes 122 are detachably or replaceably disposed on the grid 120, and the teflon tubes 122 are used to prevent the pcb from being scratched.
