[0039] The following detailed description of the present invention will make the features and advantages of the present invention more clear and explicit.

[0040] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0041] The present invention provides a universal printed circuit board support tooling for a board splitter, such as Figure 2 As shown, it includes: a pallet 10, a pallet support 11, a pallet slide rail 9 and a support column assembly.

[0042] like Figure 3As shown, the pallet 10 is a plate-frame structure, and the pallet 10 is supported on the pallet pillar 11. The pallet pillar 11 cooperates with the hole position of the pallet separator tray so that the pallet 10 can be assembled on the pallet separator tray. Preferably, a plurality of mounting holes are processed around the pallet 10, one end of the pallet pillar 11 is a threaded column, and the other end is a truncated cone structure. The outer circumference of the truncated cone is processed with grooves to form a support platform for the pallet 10. The small end of the truncated cone structure of the pallet pillar 11 penetrates from the pallet mounting hole, contacts the lower plate surface of the pallet 10 at the support platform, and supports the pallet 10. Of course, the structure and form of the pallet pillar can also be other structures, such as the pallet pillar adopts a threaded section at the lower end and a suction cup structure at the upper end, and the suction cup is used to fix the pallet, or the pallet pillar adopts a threaded section at the lower end and a threaded hole at the upper end. After the upper end supports the pallet, the pallet is fastened by bolts that cooperate with the threaded holes.

[0043] The process of cutting the edge of the printed circuit board is generally carried out after the process of installing the electronic components on the printed circuit board. The pallet support pillar can lift the entire supporting tooling away from the tray of the panel separator, providing sufficient avoidance space for the electronic components on the main body of the printed circuit board, avoiding the problem of increasing the size of the supporting tooling due to the avoidance space created by increasing the height of the pallet.

[0044] The two sides of the pallet 10 are provided with pallet slide grooves 101 for fixing the pallet slide rails 9, and scale marks such as positioning grooves and digital marks are processed on the side of the pallet slide grooves 101 of the pallet 10. Multiple pallet slide rails 9 are fixed on the pallet 10 by threaded fasteners (such as screws / bolts 8+nuts 12) passing through the pallet slide grooves 101. Positioning grooves are provided at both ends of the pallet slide rails 9, corresponding to the scale marks of the pallet, so as to facilitate the clear installation position of the pallet slide rails and improve the installation efficiency of subsequent printed circuit boards of the same type.

[0045] like Figure 4 As shown, a support column slide rail installation groove 91 is provided along the length direction on the pallet slide rail 9, and a plurality of support column assemblies are distributed and installed on the plurality of pallet slide rails 9 along the support column slide rail installation groove 91 according to the appearance of the printed circuit board with process edge. The support column assembly supports the printed circuit board with process edge, and after the support and fixation of the printed circuit board with process edge of various external dimensions are completed, the process edge cutting is performed. The support column slide rail installation groove 91 on the pallet slide rail 9 is processed with scale marks such as positioning grooves and digital marks, which is convenient for clarifying the installation position of the support column assembly and improving the installation efficiency of the subsequent printed circuit boards of the same type.

[0046] The support column assembly includes a first support column assembly and a second support column assembly.

[0047] like Figure 5 As shown, the first support column assembly includes a first rotatable support column 6, a first support column slide rail 7 and a first side fastener 5. Figure 6As shown, a longitudinal circular hole 71, a lateral threaded hole 72 and a longitudinal long hole 73 are provided on the first support column slide rail 7, the lower end of the first rotating support column 6 is located in the longitudinal circular hole 71, and the first lateral fastener 5 presses and fixes the first rotatable support column 6 from the lateral threaded hole 72; the first support column slide rail 7 is fixed to the pallet slide rail 9 by a threaded fastener passing through the longitudinal long hole 73 and the support column slide rail mounting groove 91; by adjusting the position of the threaded fastener in the longitudinal long hole 73 and rotating the first support column slide rail 7 in the plane after loosening the threaded fastener, the relative position of the first support column slide rail 7 and the pallet slide rail 9 can be adjusted, thereby driving the adjustment of the orientation of the first rotatable support column 6 to adapt to printed circuit boards of various shapes.

[0048] like Figure 7 As shown, the upper end of the first rotatable support column 6 is a step structure 61, the upper step structure passes through the process edge gap, and the lower step surface supports the printed circuit board body. The positional relationship between the first rotatable support column 6 and the printed circuit board with the process edge is shown in FIG. Fig.10 The upper step structure of the first rotatable support column 6 is used to limit the movement of the printed circuit board with process edges in the horizontal plane, so that the printed circuit board with process edges can be prevented from moving during the cutting process. The lower end of the first rotatable support column 6 includes a uniform diameter section 62 and a pressure rail section 63. The uniform diameter section is located in the longitudinal circular hole 71 of the first support column slide rail 7. The end of the first lateral fastener 5 abuts against the uniform diameter section. The outer diameter of the pressure rail section is larger than that of the uniform diameter section. It is higher than the longitudinal circular hole 71 and abuts against the upper surface of the first support column slide rail 7. The pressure rail section ensures that the first rotatable support column 6 remains vertical during the fastening process of the first lateral fastener 5 to the first rotatable support column 6. Preferably, an upper auxiliary section 64 and a lower auxiliary section 65 are provided on both sides of the uniform diameter section 62, and the upper auxiliary section 64 and the lower auxiliary section 65 are located in the longitudinal circular hole 71 of the first support column slide rail 7, and the maximum outer diameters of the two are equal to the outer diameter of the longitudinal circular hole 71 in the first support column slide rail 7; the upper auxiliary section 64 and the lower auxiliary section 65 are also conducive to keeping the first rotatable support column 6 vertical during the fastening process of the first lateral fastener 5 to the first rotatable support column 6.

[0049] like Figure 8 As shown, the second support column assembly includes a fixing plate presser screw 1, a spring 2, a plate presser 3, a second rotatable support column 4, a second support column slide rail and a second side fastener.

[0050] The second support column slide rail can adopt the same structure as the first support column slide rail 7. The second support column slide rail is provided with a longitudinal circular hole, a lateral threaded hole and a longitudinal long hole. The lower end of the second rotating support column 4 is located in the longitudinal circular hole, and the second lateral fastener presses and fixes the second rotatable support column 4 from the lateral threaded hole; the second support column slide rail is fixed to the pallet slide rail 9 by a threaded fastener passing through the longitudinal long hole and the support column slide rail mounting groove 91; by adjusting the position of the threaded fastener in the longitudinal long hole and rotating the second support column slide rail in-plane after loosening the threaded fastener, the relative position of the second support column slide rail and the pallet slide rail 9 can be adjusted, thereby driving the adjustment of the orientation of the second rotatable support column 4 to adapt to multiple types of printed circuit boards.

[0051] like Fig. 9 As shown, the upper end of the second rotatable support column 4 is flat and has a threaded blind hole. The flat surface on one side of the blind hole supports the process edge of the outer ring of the printed circuit board with the process edge. The positional relationship between the second rotatable support column 4 and the printed circuit board with the process edge is shown in FIG. Fig.10 The lower end of the second rotatable support column 4 includes a uniform diameter section and a rail pressure section. The uniform diameter section is located in the longitudinal circular hole of the second support column slide rail. The end of the second lateral fastener abuts against the uniform diameter section. The outer diameter of the rail pressure section is larger than the outer diameter of the uniform diameter section. It is higher than the longitudinal circular hole and abuts against the upper surface of the second support column slide rail. The rail pressure section ensures that the second rotatable support column 4 remains vertical during the fastening of the second lateral fastener to the second rotatable support column 4. Preferably, an upper auxiliary section and a lower auxiliary section are provided on both sides of the uniform diameter section. The upper auxiliary section and the lower auxiliary section are located in the longitudinal circular hole of the second support column slide rail. The maximum outer diameters of the two sections are equal to the outer diameter of the longitudinal circular hole in the second support column slide rail. The upper auxiliary section and the lower auxiliary section are also conducive to keeping the second rotatable support column 4 vertical during the fastening of the second lateral fastener to the second rotatable support column 4.

[0052] The plate presser 3 is located above the second rotatable support column 4, and a step hole is provided therein, and the spring 2 is placed in the step hole and supported by the step surface; the fixing plate presser screw 1 passes through the spring and cooperates with the threaded blind hole on the second rotatable support column 4 to press the process edge of the outer ring of the printed circuit board with process edge onto the second rotatable support column 4. The plate presser 3 can only cover the process edge of the outer ring of the printed circuit board with process edge, or can cover the process edge and the printed circuit board body. The plate presser covers the printed circuit board with process edge to avoid the high-power vacuum cleaner of the board separator from sucking the printed circuit board with process edge upwards during processing, which affects the fixation of the sample.

[0053] After the printed circuit board with process edge is installed and fixed on the supporting fixture, the milling cutter of the board separator passes through the process edge gap and cuts and separates the process edge from the main body of the printed circuit board at the stamp hole.

[0054] The universal printed circuit board support tooling of the panel separator is easy to operate and can be completed by one person. It adopts a double slide rail (support column slide rail + pallet slide rail) and a rotatable support column structural design, which is compatible with different types of printed circuit boards and can achieve all-round fixed support for printed circuit boards, thereby improving work efficiency and product quality, avoiding the design, manufacturing, storage and management costs of special support tooling, and providing positioning grooves and digital identification on the pallet and pallet slide rails for easy use in subsequent work.
