Abstract
Description
Technical Field
[0001] This utility model relates to the field of board separation fixture technology, specifically to a board separation fixture device for SMT processing. Background Technology
[0002] SMT (Surface Mount Technology) board separation fixtures are tools used in SMT production to divide connected circuit boards into individual board units. The board separation fixture positions the board to prevent displacement or wobbling during cutting, thus ensuring cutting accuracy. However, in existing technologies, PCB boards are not simply divided in two during separation; instead, they are divided into multiple smaller pieces. This results in the middle section of the board not being well positioned during cutting, and it is prone to jumping and shifting during the separation process, leading to poor separation results. In view of this, this paper was developed to address the above problems through in-depth research. Utility Model Content
[0003] The purpose of this invention is to provide an SMT processing board separation fixture device to solve the problem mentioned in the background art of the inability to stably position the various positions of the PCB.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example: Please refer to Figure 1-5 An SMT processing board separation fixture device includes a base 11, a plurality of support rods 9 are installed at the top of the base 11, and a base platform 4 is installed at the top of the support rods 9. A mounting platform 13 is provided above the base platform 4, and a fixture body 14 is installed at the top of the mounting platform 13. Two uprights 3 are installed on both sides of the top of the base 11, and a first electric guide rail 1 is installed at the top of the two uprights 3. Two first electric guide blocks 2 are installed inside the two first electric guide rails 1, and a second electric guide rail 6 is installed between one side of the first electric guide blocks 2 on the left and right sides. A plurality of second electric guide blocks 8 are installed inside the two second electric guide rails 6, and an electric push rod 5 is installed at the top of the second electric guide block 8. The output end of the electric push rod 5 extends to the bottom of the second electric guide block 8 and is equipped with a flexible pressure block 7.
[0021] A drive motor 12 is installed at the top center of the base 11, and the output end of the drive motor 12 is fixed to the bottom center of the mounting platform 13.
[0022] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, when using this device, the PCB board to be depaneled is placed inside the fixture body 14. Then, the first electric guide block 2 slides inside the first electric guide rail 1, causing the two sets of second electric guide rails 6 to move to the appropriate positions. Next, the electric push rod 5 is activated, causing the second electric guide block 8 to press down on the top of the PCB board. Then, a cutter is used to cut the board between the two sets of second electric guide rails 6. This process is repeated multiple times to cut the PCB board into multiple long strips. The first electric guide rail 1, first electric guide block 2, second electric guide rails 6, second electric guide block 8, and cutter are all existing technology products; their basic principles and control connections are not described here. To elaborate further, after one board separation is completed, the drive motor 12 drives the mounting platform 13 to rotate, causing the fixture body 14 to rotate the PCB board a quarter turn. Then, the number of second electric guide blocks 8 required is adjusted according to the number of rows cut at this time. It should be noted that each second electric guide block 8 is driven independently. If three rows need to be cut, three second electric guide blocks 8 are put into use and aligned with the top of the cut small pieces. Then, the cutting operation is repeated. After multiple cuts, the board separation operation of each small board can be completed. During each cut, both ends of the cutting tool are pressed to prevent the board from jumping due to the vibration of the cutting tool.
[0023] Multiple balls 17 are embedded in the top of the base 4, and multiple annular grooves are opened at the bottom of the mounting platform 13, with the top of each ball 17 contacting the top of the inside of the annular groove.
[0024] Specifically, such as Figure 1 and Figure 4 As shown, this design can reduce the resistance encountered when the mounting platform 13 rotates, and avoid wear between the base 4 and the mounting platform 13.
[0025] Multiple limiting angle plates 16 are installed on the top of the mounting platform 13, and the inner walls of the limiting angle plates 16 are all in contact with the outer wall of the fixture body 14.
[0026] Specifically, such as Figure 1 , Figure 3 and Figure 5 As shown, the limiting angle plate 16 can perform preliminary positioning on the fixture body 14 to prevent it from shifting in the horizontal direction. The fixture body 14 can be designed with different internal dimensions as needed to position the boards for different board separation requirements.
[0027] The outer wall of the fixture body 14 is provided with multiple sets of limiting grooves 18. The outer wall of the limiting angle plate 16 is fixed with two fixing boxes 15. One end of the fixing box 15 is rotatably mounted with a rotating shaft 19, and one end of the rotating shaft 19 extends to the outside of the fixing box 15 and is equipped with a knob 21. The outer wall of the rotating shaft 19 inside the fixing box 15 is fitted with a movable strip 20, and one side of the movable strip 20 is fixed with two limiting posts 10, and one end of the limiting post 10 extends into the interior of the limiting groove 18.
[0028] The outer wall of the rotating shaft 19 is provided with external threads, and the inner wall of the movable bar 20 is provided with matching internal threads.
[0029] The connection between the movable strip 20 and the fixed box 15 is a sliding connection, and the maximum movement distance of the movable strip 20 is greater than the depth of the limiting groove 18;
[0030] Specifically, such as Figure 5 As shown, rotating the knob 21 can control the rotation of the rotating shaft 19. Since the rotating shaft 19 is threadedly engaged with the movable bar 20 and the movable bar 20 is slidably connected to the fixed box 15, the movable bar 20 can move in a direction within the fixed box 15 as the rotating shaft 19 rotates, thereby driving the limiting post 10 to insert into or move away from the limiting groove 18, thus completing the quick positioning and disassembly operation of the fixture body 14.
[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
