Technical Field

[0001] The utility model relates to the field of PCB board processing equipment, in particular to a PCB board separating device. Background Art

[0002] PCBs are one of the core components of modern electronic products, playing a vital role in circuit connection and signal transmission. Cutting is an essential step in the PCB production process. To improve production efficiency, PCBs are typically produced in panels during the SMT process. Later in the SMT process, PCB panels need to be depaneled—cutting the panels into individual units for subsequent assembly and testing.

[0003] Currently, PCB depaneling is primarily accomplished through direct cutting, but existing depaneling equipment suffers from several significant drawbacks. First, for complex board shapes, existing cutting methods may not fully meet precision and shape requirements, resulting in uneven edges or unnecessary damage. More directly, physical impact during the cutting process can cause burrs on the PCB after cutting. These burrs not only affect the PCB's appearance but can also interfere with subsequent assembly and testing, and even damage electronic components. This burr problem is particularly severe for thicker PCBs, especially if the cutting equipment's rotational speed is not high enough. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Embodiment: A PCB board separation device, such as Figures 1-4 As shown, it includes a support base 1, a support frame 2, a splitter 3, a fixed block 4, a cutting plate 5, a conveying component 6, a motor 7, a lifter 8, a scraping edge cover 9, a support plate 10, an elastic column 11, an embrittlement component and a leveling component. The support base 1 is connected to the support frame 2, and the splitter 3 is installed on the support frame 2. The splitter 3 includes a cutting blade and a placement plate at the bottom. The cutting blade is slidably connected to the placement plate to cut the entire PCB board from front to back, so that the burrs on the PCB board are located on the front and back sides. The support base 1 is connected to the fixed block 4, and the fixed block 4 is connected to a cutting plate 5, a motor 7 is installed on the support base 1, a conveying assembly 6 is provided on the support base 1, one end of the conveying assembly 6 is connected to the output shaft of the motor 7, the conveying assembly 6 is located at the bottom of the rear end of the cutting plate 5, a lifter 8 is installed on the support frame 2, a scraping edge cover 9 is connected to the lifter 8, a support plate 10 is connected to the support base 1, an elastic column 11 is connected to the support base 1, the elastic column 11 is located between the two support plates 10, a brittle component for hardening burrs on the PCB board is provided on the support frame 2, and a leveling component for leveling the PCB board is provided on the fixed block 4.

[0022] like Figure 2 and Figure 3As shown, the embrittlement component includes a mounting seat 12, a cooling bag 13, a feed pipe 14, a diversion box 15 and a dry ice nozzle 16. The mounting seat 12 is connected to the support frame 2, and the cooling bag 13 is placed in the mounting seat 12. The diversion box 15 is connected to the support frame 2. One end of the feed pipe 14 is connected to the cooling bag 13, and the other end is connected to the diversion box 15. Multiple dry ice nozzles 16 are connected to the diversion box 15, and the dry ice nozzles 16 are facing the conveying component 6.

[0023] like Figure 4 As shown, the leveling assembly includes a cylinder 18, a push rod 19, a fixed plate 20, a rocker arm 21, a sliding rod 22 and a push plate 23. The cylinder 18 is installed on the fixed block 4, and the piston rod of the cylinder 18 is connected to the push rod 19. The sliding rod 22 is slidably connected to the placement plate at the bottom of the splitter 3. The fixed plate 20 is connected to the fixed block 4. The rocker arm 21 is rotatably connected to the fixed plate 20 in the middle, one end is rotatably connected to the push rod 19, and the other end is rotatably connected to the sliding rod 22. The parts of multiple sliding rods 22 passing through the placement plate are commonly connected to the push plate 23, and the push plate 23 is slidably connected to the top surface of the conveying assembly 6.

[0024] When the PCB board is transported to a certain position by the conveying assembly 6, it is separated from the conveying assembly 6 and falls on the support plate 10 and the elastic column 11, and the motor 7 stops working. The lifter 8 is then started, thereby pushing the scraping edge cover plate 9 to move downward. The scraping edge cover plate 9 contacts the PCB board on the support plate 10. The burrs on the edge of the PCB board are cleaned by squeezing the scraping edge cover plate 9 and the support plate 10. When the scraping edge cover plate 9 squeezes the PCB board, the elastic column 11 can buffer the middle part to protect the PCB board. When the lifter 8 drives the scraping edge cover plate 9 to rise, the motor 7 is started, driving the new PCB board to move onto the support plate 10, pushing out the previous PCB board, and the motor 7 and the lifter 8 cooperate to complete the deburring work one by one.

[0025] When the PCB board falls on the conveying assembly 6, the dry ice ejected from the cooling bag 13 is transported through the feeding pipe 14 and the diverter box 15, and finally ejected through the dry ice nozzle 16 to harden the burrs on the PCB board on the conveying assembly 6, thereby making it smoother to remove the burrs from the cover plate 9 and the support plate 10, and solving the problem of soft extrusion and deformation of the burrs.

[0026] When the PCB board falls on the conveying assembly 6, the cylinder 18 pushes the push rod 19 to move, and the push rod 19 drives the rocker arm 21 to rotate. The other end of the rocker arm 21 pushes the push plate 23 to move through the sliding rod 22, thereby pushing the PCB board. The distance pushed by the push plate 23 is equal to the distance between the support plate 10 and the fixed block 4. Therefore, the PCB board that moves smoothly can accurately fall on the two support plates 10, and the burrs generated by cutting at the front and back ends of the PCB board are completely removed. After falling, the tilted PCB board will also be parallel to the two support plates 10 under the action of the push plate 23. The continuous spraying of dry ice by the cooling bag 13 and the reciprocating motion of the cylinder 18 can further ensure the burr removal effect.

[0027] like Figure 4 As shown, it also includes a lighting lamp 24, and a plurality of lighting lamps 24 are installed on the support frame 2.

[0028] The lighting lamp 24 provides sufficient lighting when cutting the PCB board, ensuring a good operating vision.

[0029] like Figure 3 As shown, it also includes a guide hopper 17. A through hole is opened on the top surface of the support base 1, which is located on the side of the support plate 10, and the guide hopper 17 is connected to the through hole.

[0030] The anti-collision block 25 can prevent the staff from making right-angle contact with the surrounding of the support base 1 to avoid injury.

[0031] like Figure 1 As shown, it also includes anti-collision blocks 25, and the top corners of the support base 1 are connected with anti-collision blocks 25.

[0032] The PCB board leaving the support plate 10 falls into the guide hopper 17 and finally falls into the collection box to achieve automatic collection.

[0033] The staff first places the PCB to be cut onto the cutting plate 5, then activates the splitter 3, using the cutting blade to slide within the placement plate to complete the precise separation of the PCB. After separation, the PCB naturally falls onto the conveyor assembly 6. At this time, the motor 7 starts, driving the conveyor assembly 6 to rotate via the output shaft, conveying the PCB backward. When the PCB board breaks away from the conveyor assembly 6 and lands on the support surface formed by the support plate 10 and elastic columns 11, the motor 7 pauses and the lifter 8 starts, pushing the burr-scraping cover plate 9 downward until it contacts the PCB board. The scraping action of the burr-scraping cover plate 9 removes burrs from the edge of the PCB board. During this process, the elastic columns 11 provide a cushion for the middle portion of the PCB board, while the peripheral burrs are removed through contact with the support plate 10. After the lifter 8 resets, the motor 7 restarts, cyclically driving the new PCB board onto the support plate 10 and pushing out the processed PCB board, achieving continuous deburring. At the same time, the dry ice in cooling bladder 13 is delivered to dry ice nozzle 16 via feed pipe 14 and diverter box 15, hardening the PCB board burrs on conveyor assembly 6. This ensures smoother deburring of cover plate 9 and support plate 10, preventing burrs from being squeezed and deformed due to their softness. Furthermore, cylinder 18 propels push rod 19, which, through the transmission of rocker arm 21 and sliding rod 22, pushes push plate 23 to smoothly move the PCB boards, ensuring that each PCB board lands accurately on support plate 10 and that burrs on both the front and rear ends are completely removed.

Therefore, the scope of the present disclosure should not be limited to the above-described embodiments, but should be determined not only by the appended claims but also by the equivalents of the appended claims.
