Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of solder resist tools for circuit boards, and specifically to a universal nail bed board device for solder resist printing on circuit boards. Background Technology
[0002] Circuit boards, also known as PCBs, are important electronic components that serve as the support for electronic devices. The solder mask process on PCBs involves using screen printing technology to apply solder mask ink to the PCB substrate. For PCBs with double-sided solder mask printing, a bed of nails is required. First, the bed of nails is placed on the screen printing machine's worktable, with the back of the PCB placed on it. The screen printer then prints solder mask ink on the front of the PCB. Next, the PCB is flipped 180°, with the ink-printed front side placed on the support nails of the bed of nails. The screen printer then prints solder mask ink on the back of the PCB. Because the contact area between the support nails and the PCB is very small, it prevents the solder mask ink on the front of the PCB from being scratched, thus improving the quality of the solder mask layer.
[0003] See Figure 1 A traditional nail bed board includes a bed board 1, support nails 21, and positioning nails 31. The upper surface of the bed board 1 is a complete flat surface. The bottom of the support nail 21 is a first base block 22, and the lower surface of the first base block 22 is a complete flat surface. The bottom of the positioning nail 31 is a second base block 32, and the lower surface of the second base block 32 is a complete flat surface. Multiple support nails 21 are manually placed on the upper surface of the bed board by workers according to the actual production needs of supporting the circuit board. Then, the first base block 22 is pasted to the upper surface of the bed board 1 with tape 5 to fix the position of the support nails 21. The support nails 21 are used to support the lower surface of the circuit board 4. Similarly, the second base block 32 is pasted to the upper surface of the bed board 1 with tape 5. The positioning nails 31 are used to support the positioning holes located at the corners of the circuit board 4. The disadvantages of this nail bed board are: the use of tape for fastening leads to a waste of tape resources; when changing circuit boards of different specifications, in order to stably support the circuit boards, the staff has to tear off the tape, adjust the position of the support nails and positioning nails on the bed board, and then re-fasten it with tape; the tape fastening operation is cumbersome and inefficient.
[0004] Therefore, how to efficiently adjust and fix the position of the support nails and positioning nails on the bed board is a technical problem that urgently needs to be solved in this field. Utility Model Content

The lower surface edge of the first base block has a first wedge-shaped surface, and the first limiting pin is engaged in a limiting hole.

The positioning pin is fixedly disposed on the upper surface of the second base block, and the second limiting pin is fixedly disposed on the lower surface of the second base block. The lower surface edge of the second base block has a second wedge-shaped surface. The second limiting pin is engaged in another limiting hole, and the top of the limiting pin has a boss structure.
[0011] Furthermore, the support pin is conical in shape.
[0012] Furthermore, the positioning pin is cylindrical.
[0013] Furthermore, the sum of the number of the circuit board support components and the number of the circuit board positioning components is less than the number of the limiting holes.
[0014] Furthermore, both the circuit board support assembly and the circuit board positioning assembly are made of metal materials.
[0015] Furthermore, the bed board is made of plastic material.
[0016] Compared with the prior art, the advantages of this utility model are as follows: the support pin and the first base block are fixed to the bed board by inserting the first limiting pin into the limiting hole, and the positioning pin and the second base block are fixed to the bed board by inserting the second limiting pin into the limiting hole; the operator's hand can pull out the first limiting pin through the first wedge surface and the second limiting pin through the second wedge surface; the rectangular array of limiting holes facilitates the confirmation of spacing, and the horizontal and vertical coordinate lines facilitate the planning of the distribution of the support pin and the positioning pin on the bed board, and the position of the support pin and the positioning pin on the bed board can be adjusted and fixed efficiently according to the circuit board specifications of the actual solder resist process; the use of tape is eliminated, avoiding the waste of tape resources.

Detailed Implementation
[0027] This utility model provides a universal nail bed device for solder resist printing on circuit boards, which overcomes the shortcomings of using adhesive tape for fixing in the prior art; it achieves the technical effect of fixing by snapping into the limiting holes, which is convenient for pulling out and disassembling, and efficiently adjusting and fixing the position of the support nails and positioning nails on the bed board.
[0028] The overall concept of the technical solution of this utility model embodiment is as follows:
[0029] The worker holds the first base block of the circuit board support assembly and inserts the first limiting pin into the limiting hole. The bed board material has a certain degree of elasticity, and the limiting hole engages the first limiting pin. The lower surface of the first base block fits against the upper surface of the bed board, helping to stably support the circuit board. Similarly, the second limiting pin of the circuit board positioning assembly is engaged in the limiting holes at other locations. When the position of the circuit board support assembly needs to be adjusted, the worker's hand or a tool is inserted into the first wedge-shaped surface and then pulled outwards. When the position of the circuit board positioning assembly needs to be adjusted, the second limiting pin is pulled outwards through the second wedge-shaped surface. The rectangular array of limiting holes facilitates the confirmation of the spacing between adjacent limiting pins, and the horizontal and vertical coordinate lines facilitate the planning of the distribution of support and positioning pins on the bed board, better supporting and positioning the circuit board.
[0030] Based on the actual circuit board specifications for the solder mask process, and in conjunction with the rectangular array of limiting holes, horizontal coordinate lines, and vertical coordinate lines, the positions of the support pins and positioning pins on the bed board are efficiently adjusted and fixed. The support pins are used to lift the lower surface of the circuit board, and the boss structure of the positioning pins is used to insert into the positioning holes located at the corners of the circuit board, effectively preventing the circuit board from shaking. This invention eliminates the need for adhesive tape, avoiding the waste of tape resources.
[0031] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0032] See Figures 1 to 8 The preferred embodiment of this utility model.
[0033] A universal nail bed board device for solder resist printing on circuit boards, comprising:
[0034] Bed board 1, circuit board support assembly 2 and circuit board positioning assembly 3;
[0035] The upper surface of the bed board 1 is provided with limiting holes 11, and the multiple limiting holes 11 are in a rectangular array. The upper surface of the bed board 1 is also provided with a horizontal coordinate line 12 and a vertical coordinate line 13.
[0036] The circuit board support assembly 2 includes a support pin 21, a first base block 22 and a first limiting pin 23. The support pin 21 is fixedly disposed on the upper surface of the first base block 22, and the first limiting pin 23 is fixedly disposed on the lower surface of the first base block 22. The lower surface edge of the first base block 22 has a first wedge-shaped surface 221, and the first limiting pin 23 is engaged in a limiting hole 11.
[0037] The circuit board positioning assembly 3 includes a positioning pin 31, a second base block 32, and a second limiting pin 33. The positioning pin 31 is fixedly disposed on the upper surface of the second base block 32, and the second limiting pin 33 is fixedly disposed on the lower surface of the second base block 32. The lower surface edge of the second base block 32 has a second wedge-shaped surface 321. The second limiting pin 33 is inserted into another limiting hole 11. The top of the limiting pin is a boss structure 311.
[0038] This utility model uses a first limiting pin 23 to engage with the limiting hole 11 to fix the support pin 21 and the first base block 22 to the bed board 1, and a second limiting pin 33 to engage with the limiting hole 11 to fix the positioning pin 31 and the second base block 32 to the bed board 1. The worker's hand can pull out the first limiting pin 23 through the first wedge surface 221 and the second limiting pin 33 through the second wedge surface 321. The rectangular array of limiting holes 11 facilitates the confirmation of spacing, and the horizontal coordinate line 12 and the vertical coordinate line 13 facilitate the planning of the distribution of the support pin 21 and the positioning pin 31 on the bed board 1. According to the specifications of the circuit board 4 in the actual solder resist process, the position of the support pin 21 and the positioning pin 31 on the bed board 1 can be adjusted and fixed efficiently. The tape 5 is eliminated, avoiding the waste of tape resources caused by tape use.
[0039] like Figure 5 As shown, the limiting holes 11 on the bed plate 1 are a rectangular array of thirteen rows and eleven columns. In this embodiment, the horizontal spacing between two adjacent limiting holes is one centimeter, and the vertical spacing between two adjacent limiting holes is also one centimeter. When placing the circuit board in this invention, it is necessary to consider both the stable support of the circuit board and the avoidance of critical lines or pads on the circuit board. The positions of the circuit board support assembly and the circuit board positioning assembly on the bed plate should be flexibly adjusted, and finally, they should be engaged with the corresponding limiting holes for fixation.
[0040] The support nail 21 is conical.
[0041] The positioning pin 31 is cylindrical.
[0042] The sum of the number of the circuit board support assembly 2 and the circuit board positioning assembly 3 is less than the number of the limiting holes 11. Since the limiting holes 11 are not yet used, it is convenient to adjust the position of the circuit board support assembly 2 or the circuit board positioning assembly 3.
[0043] Both the circuit board support assembly 2 and the circuit board positioning assembly 3 are made of metal.
[0044] The bed board 1 is made of plastic material.
[0045] The working method of this utility model is as follows: According to the specifications of the circuit board 4 in the solder resist process, the operator pre-arranges the circuit board support assembly 2 and the circuit board positioning assembly 3 on the bed board 1, inserts the first limiting pin 23 into the limiting hole 11, and the lower surface of the first base block 22 is in contact with the upper surface of the bed board 1; inserts the second limiting pin 33 into another limiting hole 11, and the lower surface of the second base block 32 is in contact with the upper surface of the bed board 1; when the circuit board support assembly 2 and the circuit board positioning assembly 3 are misaligned on the bed board 1, the first limiting pin 23 is pulled out through the first wedge surface 221, and the second limiting pin 33 is pulled out through the second wedge surface 321, so as to quickly adjust the position of the circuit board support assembly 2 and the circuit board positioning assembly 3 on the bed board 1; the rectangular array of limiting holes 11 facilitates the confirmation of the spacing between two adjacent limiting pins, and the horizontal coordinate line 12 and the vertical coordinate line 13 facilitate the planning of the distribution of the support pin 21 and the positioning pin 31 on the bed board 1.
[0046] After completing the arrangement of the circuit board support assembly 2 and the circuit board positioning assembly 3, the circuit board 4 is placed on the present invention, the positioning pin 31 is inserted into the positioning hole located at the corner of the circuit board, the support pin 21 lifts the lower surface of the circuit board, and finally the screen printing machine prints solder resist ink on the upper surface of the circuit board.
[0047] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention.
