DETAILED DESCRIPTION
[0016] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments. The technical solutions in the embodiments of the utility model are clearly and completely described, and the described embodiments are only embodiments of a part of the invention, not all of it. Based on the embodiments in the invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the invention.
[0017] like Figure 1 As shown, the utility model patent designs an embodiment of a PCB board production tooling inner frame. In this embodiment, the tooling inner frame includes an inner frame body 1, and the middle part of the inner frame body 1 is a PCB board placement hole 2. The specific shape and size of the PCB board placement hole 2 can be set according to the actual shape and size of the PCB board to be produced and processed, and should be 1-3mm smaller than the size of the PCB board. The inner frame body 1 is provided with a sunken step surface edge 3 along the edge of the PCB board placement hole 2. The step surface edge 3 is about 1-3mm wide and the depth is equal to the thickness of the PCB board substrate.
[0018] The outer edge of the inner frame body 1 is also provided with a plurality of positioning notches for installation on the tooling outer frame, wherein a triangular positioning notch 7 in the shape of an equilateral triangle is provided in the middle of the lower edge of the inner frame body 1, which is used to position and limit the left and right degrees of freedom of the entire tooling inner frame installed in the middle of the tooling outer frame. Rectangular positioning notches 8 are provided in the middle of the two side edges of the inner frame body 1, and positioning blind holes 9 are opened in the horizontal direction at the centers of the rectangular positioning notches 8 on both sides, respectively. The rectangular positioning notches 8 and the positioning blind holes 9 are used to position and limit the front and back and up and down four degrees of freedom of the entire tooling inner frame installed in the middle of the tooling outer frame.
[0019] The entire inner frame is made of non-metallic insulating materials that are resistant to high temperatures, corrosion, deformation and stability through thermoplastic molding and machining processes, and can also be made entirely through machining and other processes.
[0020] Three positioning pins 6 are distributed on the left and right sides and the upper side of the step surface edge 3. The positioning pins 6 are made of hard metal alloy round bars through metal processing and embedded in the step surface edge 3 of the inner frame body 1.
[0021] Two first internally threaded metal parts 4 are symmetrically embedded on the left and right sides of the PCB board placement hole 2 along the central axis of the inner frame body 1. The two first internally threaded metal parts 4 are arranged close to the edge 3 of the step surface. The PCB board can be fixed with the help of fixing brackets and screws. They are made of metal square materials through gold processing.
[0022] Two second internally threaded metal parts 5 are symmetrically embedded in the inner frame body 1 for threaded connection with the handle with external threads, so that the entire inner frame and the assembled PCB board can be conveniently taken during the assembly process. The second internally threaded metal parts 5 are made of metal square materials through gold processing.
[0023] When the PCB board production tooling inner frame disclosed in the utility model patent is used, the PCB board substrate that has been cut and formed is first accurately positioned on the step surface edge 3 of the PCB board placement hole 2 in the inner frame body 1 using the positioning pin 6, and then the fixing bracket is installed on the first internal thread metal part 4 using screws to fix the PCB board. After that, the entire tooling inner frame is moved with the help of the threaded handle installed in the second internal thread metal part 5. When assembling, the positioning equilateral triangle boss on the tooling outer frame and the triangular positioning notch 7 on the inner frame body 1 are first matched, and then placed together on the support bracket in the middle of the tooling outer frame, and then the elastic top cones on the left and right sides of the tooling outer frame are synchronously locked, and the elastic fixed cones on both sides are pressed against the positioning blind holes 9 on both sides of the inner frame body, and the entire tooling inner frame together with the PCB board substrate is accurately positioned and fixed on the tooling outer frame, and the PCB board, the tooling inner frame and the tooling outer frame form a whole. When the PCB board needs tooling production on the assembly line of plate making, printing, packaging, dispensing and inspection, the PCB board can be smoothly carried and accurately positioned only by the outer frame of the production tooling during the entire production process. And according to different use requirements, when the shape and structure of the PCB board changes, only the shape and size of the PCB board placement hole 2 of the tooling inner frame need to be redesigned, without changing the structure of the tooling outer frame, to meet all production requirements of different PCB boards.
[0024] The above contents are only preferred embodiments of the present invention and cannot be used to limit the scope of implementation of the present invention. That is, any 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.
