[0039] like Figure 1 As shown, the present invention provides a fast and flexible support tool for printed circuit board splitting, comprising: a tool base 1, a movable support member, the movable support member is used to place a printed circuit board panel 3 above, the tool base 1 is located below the movable support member and is connected to the movable support member to provide support for the movable support member.

[0040] like Figure 2 As shown, the printed circuit board panel 3 includes a plurality of printed circuit boards, and a plurality of positioning holes 31 are provided at the edge of each printed circuit board for fixing the position of the printed circuit board during the manufacturing process.

[0041] The surface of the tooling base 1 is provided with a plurality of evenly distributed first fixing holes 11, which are arranged in a matrix, and the distances between adjacent first fixing holes 11 in the transverse direction and adjacent first fixing holes 11 in the longitudinal direction are equal; and the first fixing holes 11 are used to fix the movable support.

[0042] like Figure 3 As shown, the movable support member includes: a movable base 21, a fixing member 22, a supporting member 23 (such as Figure 1 As shown). The end of the movable base 21 is provided with a second fixing hole 211, and the surface of the movable base 21 is provided with a U-shaped groove 212, and the U-shaped groove 212 and the second fixing hole 211 are on the same axis. The top of the fixing member 22 is provided with a boss 221, and the size of the boss 221 is larger than the width of the U-shaped groove 212; the main body diameter of the fixing member 22 is smaller than the width of the U-shaped groove 212 and matches the diameter of the first fixing hole 11, and the bottom end of the fixing member 22 passes through the U-shaped groove 212 of the movable base 21 and is inserted into the first fixing hole 11 of the tooling base 1, so that the movable base 21 is fixed between the boss 221 of the fixing member 22 and the tooling base 1. The bottom end size of the support member 23 matches the diameter of the second fixing hole 211 of the movable base 21, and can be inserted into the second fixing hole 211 of the movable base 21. The middle outer surface of the support member 23 is provided with an annular limit baffle 231, which is used to determine the depth of the support member 23 inserted into the second fixing hole 211; the top end of the support member 23 is provided with a positioning structure 232, and the positioning structure 232 is a conical structure, and the bottom surface diameter of the positioning structure 232 is larger than the diameter of the positioning hole 31 of the printed circuit board, so that the top end of the support member 23 is inserted into the positioning hole 31 of the printed circuit board and stuck at the positioning structure 232 of the support member 23.

[0043] In a preferred embodiment, the outer surface of the support member 23 located above the limiting baffle 231 is further provided with a groove 233 , and a tool can be placed in the groove 233 to install or remove the support member 23 .

[0044] When using the tooling, place the tooling base 1 on a flat workbench, insert the support member 23 along the inner wall of the second fixing hole 211 of the movable base 21, until the limit stopper 231 of the support member 23 contacts the upper surface of the movable base 21, and complete the fixation of the support member 23. Determine the number and placement of the movable support members to be used according to the size of the printed board panel 3 and the position of its positioning hole 31, place the movable base 21 at the selected position, and pass the bottom end of the fixing member 22 through the U-shaped groove 212 of the movable base 21, and insert it into the appropriate first fixing hole 11 on the tooling base 1 in the U-shaped groove 212, until the boss 221 of the fixing member 22 contacts the movable base 21, and complete the fixation of the movable base 21. According to the number and position of the selected movable support parts, the fixing of the support part 23 and the fixing of the movable base 21 are repeated, and the positioning hole 31 of the printed board panel 3 is placed on the positioning structure 232 of the corresponding support part 23, and the position of the movable support part is checked to be accurate. If there is a deviation between the positioning hole 31 of the printed board panel 3 and the position of the support part 23, the position of the fixing part 22 is adjusted relative to the U-shaped groove 212 of the movable base 21 to complete the fine adjustment; if the position of the movable support part is accurate, the installed tooling is placed on the operating platform of the panel separation equipment, and the tooling can be fixed with screws or tapes, and the panel separation equipment is started to perform the panel separation operation on the printed board panel 3. The tooling is used to support the printed board panel 3, and the position of the printed board panel 3 will not move relative to each other during the panel separation process, so as to achieve high-precision and non-destructive panel separation operation.

[0045] Among them, since the movable base 21 has multiple degrees of freedom, it can rotate at any angle on the surface of the tooling base 1 with the fixing part 22 as the center; and the length of the U-shaped groove 212 of the movable base 21 can be designed as needed, thereby increasing the adjustable distance of the fixing part 22 in the U-shaped groove 212 and improving the flexibility of the movable support. Therefore, before the boss 221 of the fixing part 22 contacts the movable base 21, the movable base 21 can be adjusted at multiple angles and positions on the tooling base 1, which facilitates the installation of the tooling.

[0046] Embodiment 1

[0047] This embodiment uses a threaded structure to enhance the stability of the connection between the tooling base 1 and the fixing member 22, and between the movable base 21 and the support member 23. Specifically, the inner wall of the first fixing hole 11 of the tooling base 1 is provided with an internal thread, and the bottom end of the fixing member 22 is provided with an external thread matching the first fixing hole 11, so that the fixing member 22 and the tooling base 1 are connected together by threads. The inner wall of the second fixing hole 211 of the movable base 21 is provided with an internal thread, and the bottom end of the support member 23 is provided with an external thread matching the inner wall of the second fixing hole 211, so that the support member 23 and the movable base 21 are connected together by threads.

[0048] like Figure 4 , Figure 5 As shown, the arrangement positions of the plurality of first fixing holes 11 on the tooling base 1 are further optimized, the spacing between adjacent first fixing holes 11 on the tooling base 1 is set to D, and the distance between the center a of the second fixing hole 211 of the movable base 21 and the center b of the end of the U-shaped groove 212 away from the second fixing hole 211 is regarded as the effective length L of the movable base 21. The spacing D of the first fixing holes arranged in an array on the tooling base 1 is matched with the effective length L of the movable base 21. When When the movable base 21 is fixed on a first fixing hole 11 of the tooling base 1, the farthest distance that the support member 23 can support is the distance between adjacent first fixing holes 11 on the diagonal line, thereby ensuring the effectiveness of the position setting of the first fixing holes 11 on the tooling base 1 and reducing the number of first fixing holes 11 on the tooling base 1, which can effectively avoid the unreasonable layout of the inner wall threads caused by the dense arrangement of the first fixing holes 11 on the tooling base 1 and the mutual interference of multiple movable bases 21 during installation.

[0049] like Figure 6 As shown, the support member 23 is further optimized. The taper C of the positioning structure 232 of the support member 23 is less than 0.8, ensuring that the positioning hole 31 of the printed circuit board can be nested in the middle part of the positioning structure 232, and the fixation of the printed circuit board panel 3 is more stable; due to the limited internal space of the panel separation equipment, the taper range of the positioning structure 232 of the support member 23 is preferably 0.5-0.8.

[0050] In summary, the tooling of the present invention can change the supporting position for different printed circuit board panels by simply adjusting the movable base, thereby supporting different printed circuit board panels, improving the flexibility of the support tooling, greatly reducing the cost of putting special tooling into production and the subsequent management cost, and facilitating rapid board or line change in production and easy replication.
