DETAILED DESCRIPTION
[0022] 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.
[0023] like Figure 1 , 2 As shown, the utility model patent designs an embodiment of a multi-purpose PCB board production tooling. In this embodiment, the production tooling includes a tooling inner frame 2 and a tooling outer frame 1. The tooling outer frame 1 and the tooling inner frame 2 are both made of non-metallic insulating materials that are resistant to high temperature, corrosion, not easy to deform, and have stable performance through thermoplastic molding and machining processes. The middle part of the tooling outer frame 1 is provided with an inner frame assembly hole with the same shape as the tooling inner frame 2, and the middle part of the tooling inner frame 2 is provided with a PCB board assembly hole 21. The tooling inner frame 21 is assembled and fixed in the inner frame assembly hole of the tooling outer frame 1, and is connected and fixed by a locking mechanism.
[0024] The tooling inner frame 2 is provided with a circle of sunken step surface 22 along the edge of the PCB assembly hole 21, and three positioning pins 23 are distributed and fixed on the step surface. The step surface 22 is about 3mm wide, and its sunken height is the same as the thickness of the PCB board. The fixed positions of the three positioning pins 23 correspond to the positions of the three positioning holes on the PCB board to be produced and processed.
[0025] The tooling inner frame 2 is respectively embedded with first internally threaded metal parts 24 on the left and right sides of the PCB board assembly hole 21. The two first internally threaded metal parts 24 are arranged on the central axis of the tooling inner frame 2, close to the left and right sides of the PCB board assembly hole 21, respectively. The first internally threaded metal parts 24 are used to be threadedly connected to the PCB board fixing parts, and are used to fix the assembled PCB board. Two second internally threaded metal parts 25 are also symmetrically embedded on the frame of the tooling inner frame 2. The second internally threaded metal parts 25 are used to be threadedly connected to the inner frame moving handle, so as to facilitate the removal and movement of the tooling inner frame 2.
[0026] A triangular positioning notch 28 is provided at the center of the lower outer edge of the tooling inner frame 2. Rectangular positioning notches 26 are provided at the center of the left and right outer edges of the frame body, and positioning blind holes 27 are provided symmetrically in the horizontal direction at the centers of the rectangular positioning notches 26 on both sides.
[0027] The size of the inner frame assembly hole in the middle of the tooling outer frame 1 is slightly larger than that of the tooling inner frame 2 by 1-3 mm, which is convenient for the assembly of the tooling inner frame 2. Three stepped support brackets 11 are distributed in a finished shape along the edge of the inner frame assembly hole. The support bracket 11 is fixed to the frame body of the tooling outer frame 1 by screws, and the part extending into the inner frame assembly hole is stepped. The height of the step is the same as the thickness of the tooling inner frame 2, and the bottom edge of the tooling inner frame 2 is pressed on the three support brackets 11.
[0028] The tooling outer frame 1 has a triangular positioning protrusion 13 of the same size as the triangular positioning notch 28 of the tooling inner frame 2 protruding from the middle position on the lower side of the inner frame assembly hole toward the center of the inner frame assembly hole, which is used to position and limit the left and right degrees of freedom of the tooling inner frame 2 installed in the middle of the tooling outer frame 1.
[0029] The left and right sides of the frame of the tooling outer frame 1 are respectively provided with locking mechanisms for fixing the tooling inner frame 2 along the central axis. The locking mechanisms are top cone fasteners 12, including set screws 121, compression springs 122, push rods 123 and top cones 124. The two sides of the frame of the tooling outer frame 1 are respectively provided with transverse holes that penetrate horizontally along the central axis. The transverse holes on both sides are located on the same axis as the positioning blind holes 27 on both sides of the frame of the tooling inner frame 2. The outer sections of the transverse holes on both sides are respectively embedded with internal threaded metal inserts 16. The push rod 123 of the top cone fastener 12 is slidably connected in the transverse hole, and the set screw 121 is threadedly connected in the internal threaded metal insert 16. A hexagon socket countersunk screw is used. The inner end of the set screw 121 is connected to one end of the push rod 123 through the compression spring 122. The top cone 124 is connected to the other end of the push rod 123 and exposed from the inner end of the transverse hole. The top cone 124 is in a square shape, and its outer dimensions are adapted to the dimensions of the rectangular positioning notch 26 of the tooling inner frame 2, and it can slide in the positioning notch 26. An internal threaded hole is provided on one side of the top cone 124, which is threadedly connected to the end of the top rod 123, and a conical head is provided on the other side, which is pressed tightly against the positioning blind hole 27 of the tooling inner frame 2 to achieve the fixation of the tooling inner frame 2 in the tooling outer frame 1. By adjusting the threaded assembly position of the top rod 123 and the top cone 124, the compression degree of the compression spring 122 can be adjusted, thereby increasing or decreasing the tightening force of the top cone fastener 12.
[0030] In addition, positioning holes 14 with the same diameter are symmetrically opened at the four corners of the tooling outer frame 1, and two positioning notches 15 are symmetrically opened on the outer edge of the upper side of the tooling outer frame 1. The positioning holes 14 and the positioning notches 15 are used for connecting and positioning the tooling outer frame with the production and processing equipment.
[0031] When the multi-purpose PCB board production tooling disclosed in the utility model patent is used, first, the blanked and formed PCB board substrate is accurately positioned on the edge step surface 22 of the PCB board assembly hole 21 of the tooling inner frame 2 using the positioning pin 23, and the fixing piece is installed in the first internal thread metal piece 24 with screws to fix the PCB board, and then the tooling inner frame 2 with the PCB board fixed is picked up with the help of a threaded handle, and the triangular positioning protrusion 13 on the tooling outer frame 1 is matched with the triangular positioning notch 28 on the tooling inner frame 2, and then the tooling inner frame 2 is placed on the three supporting brackets 11 in the middle of the tooling outer frame 1, and then the top cone fasteners 12 on the left and right sides of the tooling outer frame 1 are synchronously locked by screwing the fixing screws 121 on both sides to complete the fixing of the tooling inner frame 2, and the PCB board, the tooling inner frame 2 and the tooling outer frame 1 form a whole. When the PCB board needs tooling production on the assembly line of plate making, printing, packaging, dispensing and inspection, the whole process only needs to be positioned and installed by the tooling outer frame 1 and the production and processing equipment, so as to realize the smooth transportation and precise positioning of the PCB board. According to different use requirements, when the shape and structure of the PCB board changes, it is only necessary to redesign the structure of the PCB board assembly hole 21 of the tooling inner frame 2 without changing the structure of the tooling outer frame 1, so as to meet the production requirements of different PCB boards.
[0032] 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.
