Description

Technical Field

[0001] This utility model relates to the field of PCB depaneling machines, and in particular to a milling cutter type PCB depaneling machine. Background Technology

[0002] Milling cutter-type PCB separators use high-speed rotating carbide milling cutters to cut along pre-planned paths on circuit boards, thus dividing a single, continuous panel into multiple independent smaller boards. The movement of the milling cutter is typically adjusted via a three-axis translation mechanism and a CNC system, in conjunction with a high-resolution camera for positioning and alignment, achieving high-precision cutting. Fine dust is generated during the cutting process, which is usually sucked up through dust extraction ports around the milling cutter. However, in some cases, the dust gradually accumulates and becomes compacted in the gaps between the milling cutter blades, making it difficult to remove by dust extraction alone, thus affecting the normal use of the milling cutter. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a milling cutter-type PCB separator, which facilitates dust blowing and brushing cleaning of the milling cutter after PCB separation, resulting in good cleaning performance and ensuring long-term normal use of the cutter.

The second bracket connects to the edge of the fan blade and is located on the top of the fan blade. The brush is located on the second bracket.

[0007] In a further technical solution, the first bracket includes a support block and a support arm. The support block is located in the middle of the sleeve, and the two ends of the support arm are respectively connected to the support block and the inner wall of the sleeve.

[0024] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0025] Example:

[0026] like Figures 1-4 As shown, a milling cutter type PCB separator includes a three-axis drive assembly 10, a milling cutter head 20, a base 30, and a cleaning device 40. The three-axis drive assembly 10 can be any mechanism capable of linear drive in the three vertical directions of the "XYZ" axes. In this embodiment, it can specifically be a Y-axis guide rail, an X-axis guide rail, a Z-axis guide rail, and a gantry frame. The Y-axis guide rail is located on both sides of the base 30, and the bottom ends of the gantry frame are connected to the Y-axis guide rail. The X-axis guide rail is located on the gantry frame, and the Z-axis guide rail is located on the X-axis guide rail. The Y-axis guide rail, X-axis guide rail, and Z-axis guide rail are driven by a CNC system. The milling cutter head 20 is connected to the three-axis drive assembly 10 through a mounting plate 11. A dust collection hood 21 is provided on the outside of the cutter of the milling cutter head 20, and the dust collection hood 21 has a dust collection hole that communicates with the dust collection system.

[0027] The aforementioned CNC system, milling cutter head 20, and dust collection system all adopt any existing milling cutter PCB separator structure that can meet the requirements of this application.

[0028] The cleaning device 40 includes a sleeve 41, a blower 42, a first bracket, a fan blade 44, a second bracket, and a brush 46. The sleeve 41 is located on the top of the base 30, and the bottom of the sleeve 41 has an air inlet 411. The blower 42 is located inside the bottom of the sleeve 41 near the air inlet 411. The first bracket is located on top of the blower 42 and includes a support block 431 and support arms 432. The support block 431 is located in the middle of the sleeve 41, and the support arms 432 include at least three arms arranged in a circular array outside the support block 431, with their ends connected to... The inner wall of the sleeve 41 is connected; the bottom center of the fan blade 44 is provided with a rotating shaft 441 aligned with the sleeve 41; the top center of the support block 431 is provided with a bearing connecting the rotating shaft 441; the outer edge of the fan blade 44 is provided with a connecting ring 442; the second bracket includes an mounting strip 451 and a support ring 452; the mounting strip 451 is vertically arranged on the top of the connecting ring 442; the support ring 452 coincides with the central axis of the connecting ring 442 and is located at the top of the mounting strip 451; the brush 46 is strip-shaped and vertically arranged on the mounting strip 451, facing the inner side of the second bracket.

[0029] The working principle of the above technical solution is as follows:

[0030] After the milling cutter head 20 completes the cutting of a panel, the three-axis drive assembly 10, under the existing CNC system programming, drives the milling cutter head 20 to move to the sleeve 41, and moves the milling cutter into the sleeve 41. At this time, the blower device 42 can be turned on, and air is drawn in from the air inlet 411 and blown towards the fan blade 44 and the milling cutter. At the same time, the blower blows the fan blade 44 to rotate, which drives the brush 46 on the second bracket to rotate around the milling cutter. The air force, together with the friction of the brush 46, cleans the dust accumulated in the gap of the milling cutter. The dust is sucked away by the dust suction hood 21 on the milling cutter head 20 to complete the cleaning.

[0031] In another embodiment, such as Figure 3 As shown, the brush 46 includes a retaining plate 461 and brush bristles 462 disposed on the retaining plate 461. Elastic fasteners 463 are respectively provided on both sides of the retaining plate 461 on the side where the brush bristles 462 are located. The mounting strips 451 are arranged in pairs, including multiple pairs, and are arranged in a ring array on the top side of the connecting ring 442. There is an installation gap between the same pair of mounting strips 451 for the brush bristles 462 to pass through. The mounting strips 451 are provided with fastening holes 4511 adapted to the elastic fasteners 463. When the elastic fasteners 463 are fastened to the fastening holes 4511, the brush 46 passes through the installation gap.

[0032] The brush 46 has a modular structure and can be disassembled relative to the second bracket, making it convenient to clean and replace the brush 46.

[0033] In another embodiment, such as Figure 1As shown, the sleeve 41 can be located at the edge of the base 30, within the range of motion of the milling cutter head 20.

[0034] Avoid interfering with the plate separation operation.

[0035] In another embodiment, such as Figure 2 As shown, the air inlet 411 includes multiple inlets, which are evenly arranged in a ring array on the bottom side wall of the sleeve 41; a dustproof net 412 is provided at the air inlet 411.

[0036] The dustproof net 412 reduces the amount of external dust entering the sleeve 41, thus minimizing its impact on the cleaning effect.

[0037] In another embodiment, the blower 42 is an ion fan.

[0038] Ionizing fans can eliminate static electricity in powder and prevent powder from adhering to the milling cutter surface due to static electricity.

[0039] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
