Description

Technical Field

[0001] The utility model relates to the technical field of PCBA processing, in particular to a universal PCBA board separation device. Background Art

[0002] PCB production generally uses a panelization process, where components are mounted and soldered onto the PCB to form PCBA assemblies for practical use. However, depaneling PCBAs, which contain various components, can be quite challenging. The PCBAs must be protected from stress during the depaneling process, as this can easily damage the components. Existing depaneling methods often use V-cut depaneling machines or automatic curved depaneling machines. V-cut depaneling machines are primarily designed for linearly spliced PCBAs and are more suitable for regularly shaped PCBAs. Automatic curved depaneling machines are primarily used for irregular, non-linear PCBAs, requiring the use of various depaneling devices to cope with the depaneling process. Therefore, current depaneling devices are still not suitable for depaneling multiple varieties of PCBAs with different specifications and in small quantities.

[0003] Existing PCB depaneling devices are complex in structure, costly, inefficient, and lack the ability to meet today's rapidly evolving needs. Among them, Chinese utility model patent No. CN205799692U discloses a PCB depaneling device designed to improve depaneling efficiency. However, the disclosed depaneling device is still incompatible with PCBs of varying specifications and requires different positioning bars during use, making reference positioning difficult and complex. It also requires different positioning pins to accommodate the automatic hole alignment of the PCB board. Utility Model Content

[0004] In view of the defects in the prior art, the present invention provides a universal PCBA depaneling device to solve the problem that the current depaneling device has a complex structure and is still unable to use PCB boards of different specifications.

[0005] The utility model provides a universal PCBA board separation device, comprising:

[0006] A fixed bottom plate, wherein the fixed bottom plate is provided with slide grooves, and the slide grooves are arranged in parallel;

[0007] At least two sets of slide plate assemblies, both ends of the slide plate assemblies being slidably connected to the slide grooves;

[0008] The support assembly is arranged on the slide assembly. Each slide assembly is provided with at least two support assemblies, and at least one of the two support assemblies is slidably connected to the slide assembly.

[0009] It can be seen from the above technical solution that the universal PCBA depaneling device provided by the present invention can be applied to depaneling operations of PCBAs of different rules through the slide assembly and the support assembly provided on the slide assembly.

[0010] Optionally, positioning pins are provided at both ends of the slide assembly, and the positioning pins pass through the slide slots and are connected to nuts. The slide assembly slides within the slide slots to freely adjust the width between the slides.

[0013] It can be seen from the above technical solution that the skateboard assembly includes a skateboard assembly I for reference positioning and a skateboard assembly II for adapting to different rules. First, the reference positioning of one corner of the PCBA is achieved through the skateboard assembly I, and then the other slidable support assembly on the skateboard assembly I is used to achieve the positioning of the other corner on the same side. Then, the support assembly on the skateboard assembly II is used to achieve the positioning of the two corners on the other side, ensuring the positioning effect of the PCB.

[0014] Optionally, a support stud is provided on the top of the support block. Positioning holes are formed on the four corners of the PCBA, and the positioning holes are inserted into the support stud to achieve the positioning of the PCBA.

[0015] Optionally, a locking screw is provided through the side of the support assembly to achieve positioning of the support assembly based on the slide assembly, thereby ensuring a positioning effect for the PCBA.

[0016] Optionally, the fixed base plate is provided with a fixing hole for connecting to a board separator.

[0017] By adopting the above technical solution, this application has the following technical effects:

[0018] The universal PCBA depaneling device provided by the utility model can be applied to depaneling operations of PCBAs with different regularities through the slide assembly and the support assembly provided on the slide assembly. After the four positioning holes of the PCBA are positioned respectively by the support assembly, locking the support assembly can realize the positioning operation during PCBA depaneling and ensure the positioning effect.

[0030] like Figure 1 As shown, the present embodiment provides a universal PCBA board separation device, comprising a fixed base plate 1, at least two groups of slide plate assemblies 2 and a support assembly 3. The fixed base plate 1 is provided with a slide groove 11, and the slide groove 11 is arranged in parallel; both ends of the slide plate assembly 2 are slidably connected to the slide groove 11; the support assembly 3 is arranged on the slide plate assembly 2, and each slide plate assembly 2 is provided with at least two support assemblies 3, and at least one of the two support assemblies 3 is slidably connected to the slide plate assembly 2.

[0031] The universal PCBA depaneling device provided in this embodiment can be applied to depaneling operations of PCBAs of different rules through the slide assembly 2 and the support assembly 3 provided on the slide assembly 2; after the four positioning holes of the PCBA are positioned respectively through the support assembly 3, locking the support assembly 3 can realize the positioning operation during PCBA depaneling and ensure the positioning effect.

[0032] Optionally, positioning pins 22 are provided at both ends of the slide assembly 2. The positioning pins 22 pass through the slide groove 11 from the bottom of the fixed base plate 1 and are connected to nuts 23 at the top. The slide assembly 2 slides in the slide groove 11, and the width between the slide assemblies 2 can be freely adjusted. When the width between the slide assemblies 2 is adjusted to a suitable position, the position between the slide assemblies 2 can be fixed by a locking nut, which facilitates the subsequent operation of the board separator.

[0033] In a specific embodiment, a butterfly nut is used to lock the positioning pin 22 to position the slide assembly 2. The butterfly nut can adjust the position of the slide assembly 2 without tools, which is easy to operate.

[0034] like Figure 2-3 As shown, a slide rail 21 is formed on the slide plate assembly 2, and the support assembly 3 includes a support block 31. A groove is formed at the bottom of the support block 31, and the groove and the slide rail 21 are arranged in coordination.

A slidable support assembly on slide assembly I then positions the other corner on the same side. Finally, the support assembly 3 on slide assembly II positions both corners on the other side, ensuring the proper positioning of the PCB.

[0036] In one embodiment, a through-hole 24 is defined in the side of the slide rail of slide assembly I. A locking screw 33 passes through one end of a support block 31, the slide rail 21, and then the other end of the support block 31, securing the support assembly 3 to the slide rail 21. This serves as a reference for positioning the support assembly 3. For the remaining slidable support assemblies 3, locking screws 33 extend through both ends of the support block 31 and abut against the slide rail 21, allowing for flexible adjustment to accommodate PCBAs of varying specifications.

[0037] like Figure 4 As shown, a support stud 32 is provided on the top of the support assembly 3. Positioning holes are formed on the four corners of the PCBA, and the positioning holes are inserted into the support stud 32 to achieve the positioning of the PCBA.

[0038] Optionally, a locking screw 33 is provided through the side of the support assembly 3. The locking screw 33 is used to realize the positioning of the support assembly 3 based on the slide assembly 2, thereby ensuring the positioning effect for the PCBA.
