Description

Technical Field

[0001] This invention relates to the field of PCB board cutting equipment technology, specifically to a PCB board cutting device with a self-cleaning function. Background Technology

[0002] PCB board cutting (separation) is a core process in electronic manufacturing that separates panelized boards into individual boards. V-CUT machines are specialized electronic manufacturing equipment used to separate PCB circuit boards with pre-set V-grooves. Their core function is to accurately separate individual boards along the V-grooves on the PCB panel, significantly reducing cutting stress and avoiding solder cracking at the board edges. They are one of the core cutting equipment in the PCB mass production process. V-CUT machines are widely used for regular rectangular materials such as PCB boards with V-CUT grooves, LED light strips, copper-based boards, aluminum-based boards, and FR4 fiberglass boards.

[0003] Existing PCB board cutting devices mostly use a reciprocating feeding method. This feeding method only allows the next PCB board to be fed after the previous PCB board has been cut and removed from the feeding fixture. It cannot achieve streamlined feeding and has low work efficiency.

[0004] For example, the aforementioned problem exists in patent (CN119589259A); it describes "a CNC V-CUT machine with positioning function, including a slot on the top surface of the V-CUT machine body and a grid platform installed on the inner wall of the slot. The top of the grid platform is equipped with a positioning mechanism for multiple limiting along the sides and top surface of the plate to be V-shaped cut. Inside the V-CUT machine body is a displacement component for driving the positioning mechanism to move along the front and rear axial direction and cooperating with the rear wall of the V-CUT machine body to form a front and rear clamping state of the plate to be V-shaped cut. The positioning mechanism includes components placed on the grid platform..." The frame structure connected to the displacement component on the top surface of the platform has several spring structures installed on the bottom wall of the frame structure. This invention can position and clamp the front, back, sides and top surface of the board to be cut, and the sides and top surface use the same drive source, which effectively reduces the complexity of the overall structure and maintenance costs. The V-CUT machine in the above patent drives the PCB board to perform reciprocating feeding through the displacement component 4. This feeding method can only feed the next PCB board after the previous PCB board has been cut and removed from the feeding fixture. It cannot achieve streamlined feeding and has low work efficiency.

[0005] The existing PCB cutting devices generally use a reciprocating feeding method. This method only allows the next PCB to be fed after the previous PCB has been cut and removed from the feeding fixture. This method cannot achieve streamlined feeding and results in low work efficiency. Therefore, we propose a PCB cutting device with a self-cleaning function. Summary of the Invention

[0006] The purpose of this invention is to provide a PCB board cutting device with a self-cleaning function to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a PCB board cutting device with self-cleaning function, including a feeding rack, a cutting and cleaning rack, and a receiving rack. The cutting and cleaning rack is disposed between the feeding rack and the receiving rack. A PCB board conveying mechanism is horizontally provided on the top of the feeding rack. The PCB board conveying mechanism includes two sets of rotary conveying components arranged symmetrically above and below. Each rotary conveying component includes several rotary conveyor belts that rotate. An isolation strip is provided at the center of the outer wall of each rotary conveyor belt. A work box is provided on the top of the cutting and cleaning rack. PCB board conveying ports are respectively opened on both sides of the work box. A cutting component and a cleaning component are disposed inside the work box. The cleaning component is disposed between the cutting component and the receiving rack.

[0008] Furthermore, the rotary conveyor assembly also includes support wheels disposed on the inner sides of both ends of the rotary conveyor belt. The two sets of rotary conveyor assemblies are symmetrically arranged with drive wheel assemblies for the rotary conveyor belt. Each drive wheel assembly includes a drive frame and a drive motor. The drive frame has a drive wheel and an auxiliary wheel that match the rotary conveyor belt rotatably disposed on its inner side. The drive wheel and the auxiliary wheel are staggered vertically. The output end of the drive motor is connected to the drive wheel via a transmission rod. The drive frame also has a tension wheel assembly that matches the rotary conveyor belt. The tension wheel assembly includes a rotatably disposed tension wheel. The auxiliary wheel and the tension wheel are located on the same horizontal line. The outer walls of both the auxiliary wheel and the tension wheel are provided with a first annular groove that matches the isolation strip.

[0009] Furthermore, the transmission rod has a regular hexagonal cross-section, and the support shaft of the drive wheel has an internal hexagonal through groove that matches the transmission rod.

[0010] Furthermore, the cutting assembly includes a first support roller and a second support roller. The first support roller is positioned above the second support roller. The outer wall of the first support roller is fitted with a plurality of cutting discs. The cutting discs are parallel to the center line of the spacing between two adjacent sets of vertically distributed rotary conveyor belts. The top of the outer wall of the second support roller is provided with a bracket below the cutting discs. The second support roller is fixedly connected to the inner wall of the work box.

[0011] Furthermore, the bracket includes a V-shaped support base, with guide wheels rotatably mounted at both ends of the top of the V-shaped support base, and a second annular groove matching the cutting disc is provided at the center of the outer wall of the guide wheel.

[0012] Furthermore, the first support roller, the second support roller, and the guide wheel are parallel to each other, the first support roller is perpendicular to the rotary conveyor belt, and the guide wheel is parallel to the drive wheel.

[0013] Furthermore, the cleaning component includes an elastic swing frame symmetrically distributed vertically, a V-shaped frame rotatably provided at the output end of the elastic swing frame, and a cleaning roller rotatably provided at both ends of the V-shaped frame, with bristles provided on the outer wall of the cleaning roller.

[0014] Furthermore, the elastic swing frame includes a swing arm, one end of which is rotatably connected to a connecting rod at the center of the V-shaped frame, and the other end of which is fitted with a rotatably connected support rod. A torsion spring is provided between the support rod and the swing arm, and the support rod is fixedly connected to the inner wall of the work box.

[0015] Furthermore, the V-shaped frame is perpendicular to the connecting rod, the cleaning roller, the connecting rod, and the support rod are parallel to each other, and the support rod is perpendicular to the rotary conveyor belt.

[0016] Furthermore, the receiving rack and the feeding rack have the same structure and are arranged flush with each other. The cutting and cleaning rack is equipped with a dust collection device below the work box.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are: This invention, through the arrangement of a feeding rack, a cutting and cleaning rack, a receiving rack, a PCB board conveying mechanism, a rotary conveyor assembly, a rotary conveyor belt, a separator strip, a cutting assembly, and a cleaning assembly, with the feeding rack, cutting and cleaning rack, and receiving rack working together, allows for streamlined continuous feeding, cutting, cleaning, and receiving of PCB boards simply by placing them inside the feeding rack. Two vertically distributed rotary conveyor belts form a streamlined clamping conveyor line, and adjacent sets of two vertically distributed rotary conveyor belts form two streamlined clamping conveyor lines. The space between these two clamping conveyor lines serves as the PCB board feeding and conveying channel. When the PCB board is placed between adjacent sets of two vertically distributed rotary conveyor belts, it is placed inside the conveying channel, and the rotary conveyor belt's rotational motion drives the PCB board through a streamlined clamping and conveying process. The system consists of two streamlined clamping conveyor lines divided by a partition strip, which effectively increases the number of PCB board feeding channels and thus the number of PCB boards processed simultaneously. The cutting component cuts the PCB boards inside the work box, and the cleaning component cleans them inside the work box. The PCB boards are then removed from the work box through the PCB board conveyor port and enter the receiving rack for further receiving and unloading. The width of the PCB board feeding channel can be adjusted by changing the horizontal spacing between two adjacent sets of vertically distributed rotary conveyor belts, thus accommodating PCB boards of different widths. Similarly, the height of the PCB board feeding channel can be adjusted by changing the vertical spacing between the vertically distributed rotary conveyor belts, thus accommodating PCB boards of different thicknesses.

[0018] This invention, by setting up a first support roller, a second support roller, a cutting disc, a bracket, an elastic swing frame, a V-shaped frame, and a cleaning roller, allows the PCB board to enter the work box and then move between the cutting disc and the bracket. The bracket provides rolling support to the bottom of the PCB board, while the cutting disc performs cutting processing on the top of the PCB board, ensuring the safety and stability of the PCB board during the cutting process. The elastic swing frame provides elastic swing support to the V-shaped frame, and the two sets of cleaning rollers distributed vertically can simultaneously clean the upper and lower surfaces of the PCB board. Supported by the elastic swing frame, the cleaning rollers and the P... The PCB board's upper and lower surfaces are in elastic contact during cleaning, effectively preventing damage to the PCB board during the cleaning process. The swing arm, through the connecting rod, can rotate and support the V-frame, allowing the V-frame to self-adjust. This ensures that the bristles on the outer walls of the two cleaning rollers on the V-frame can make close rolling contact with the upper and lower surfaces of the PCB board, thereby improving the cleaning effect. The design of the support rod and torsion spring allows the swing arm to swing elastically, enabling the cleaning rollers to adapt to PCB boards of different thicknesses while ensuring the effective rolling cleaning of the cleaning roller bristles against the PCB board.

Example

[0021] Please see Figures 1-8 This invention provides a technical solution: a PCB board cutting device with self-cleaning function, including a feeding rack 1, a cutting and cleaning rack 2, and a receiving rack 3. The cutting and cleaning rack 2 is located between the feeding rack 1 and the receiving rack 3. A PCB board conveying mechanism 4 is horizontally arranged on the top of the feeding rack 1. The PCB board conveying mechanism 4 includes two sets of rotary conveying components 5 arranged symmetrically. Each rotary conveying component 5 includes several rotary conveyor belts 501 that rotate. A separation strip 502 is provided at the center of the outer wall of each rotary conveyor belt 501. A work box 201 is located on the top of the cutting and cleaning rack 2. PCB board conveying ports 202 are respectively opened on both sides of the work box 201. A cutting component 6 and a cleaning component 7 are arranged inside the work box 201. The cleaning component 7 is located between the cutting component 6 and the receiving rack 3. The rotary conveying component 5 also includes support wheels 503 arranged on the inner sides of both ends of the rotary conveyor belts 501. The two sets of rotary conveying components 5 are arranged symmetrically. A drive wheel assembly 8 with a rotary conveyor belt 501 includes a drive frame 801 and a drive motor 804. The drive frame 801 has a drive wheel 802 and an auxiliary wheel 803 rotatably mounted on its inner side, matching the rotary conveyor belt 501. The drive wheel 802 and the auxiliary wheel 803 are staggered vertically. The output end of the drive motor 804 is connected to the drive wheel 802 via a transmission rod 805. The drive frame 801 also has a drive wheel assembly 8 that matches the rotary conveyor belt 501. 1. A matching tensioning wheel assembly 807, the tensioning wheel assembly 807 includes a rotatably configured tensioning wheel 808, the auxiliary wheel 803 and the tensioning wheel 808 are located on the same horizontal line, and the outer walls of the auxiliary wheel 803 and the tensioning wheel 808 are provided with a first annular groove 809 that matches the isolation strip 502; the receiving rack 3 has the same structure as the feeding rack 1, and the receiving rack 3 and the feeding rack 1 are distributed flush; the cutting and cleaning rack 2 is provided with a dust collection device below the work box 201.

[0022] In one embodiment, the transmission rod 805 has a regular hexagonal cross-section, and the support shaft of the drive wheel 802 has an internal hexagonal slot 806 that matches the transmission rod 805. By adopting a specially shaped transmission rod 805 and internal hexagonal slot 806, it is ensured that one drive motor 804 can normally drive multiple drive wheels 802 to rotate through one transmission rod 805 and internal hexagonal slot 806. The drive wheels 802 drive the rotary conveyor belt 501 to rotate, and the rotary conveyor belt 501 drives the PCB board to perform conveying work.

[0023] Working principle of the invention: Refer to the instruction manual appendix Figures 1-8 This invention comprises a feeding rack 1, a cutting and cleaning rack 2, a receiving rack 3, a PCB board conveying mechanism 4, a rotary conveyor assembly 5, a rotary conveyor belt 501, a separator strip 502, a cutting assembly 6, and a cleaning assembly 7. The feeding rack 1 is used for streamlined and continuous feeding of PCB boards to the cutting and cleaning rack 2, and the receiving rack 3 is used for receiving the cut and cleaned PCB boards. With the cooperation of these three components, once the PCB board is placed inside the feeding rack 1, streamlined and continuous feeding of the PCB board can be completed. The PCB board conveying mechanism 4 consists of two symmetrically arranged rotary conveyor components 5. The upper rotary conveyor component 5 uses a rotary conveyor belt 501 to press and convey the top of the PCB board, while the lower rotary conveyor component 5 uses a rotary conveyor belt 501 to support and convey the bottom of the PCB board. The two vertically distributed rotary conveyor belts 501 form a streamlined clamping conveyor line. The two adjacent vertically distributed rotary conveyor belts 501... The system consists of two streamlined clamping conveyor lines, with the space between them serving as the PCB board feeding and conveying channel. The PCB board is placed between two adjacent sets of vertically distributed rotary conveyor belts 501, allowing it to be placed inside the conveying channel. The rotary conveyor belts 501 rotate, driving the PCB board through a streamlined clamping conveying process. A separator strip 502, located at the center of the rotary conveyor belts 501, divides one conveyor belt 501 into two streamlined clamping conveyor lines, effectively increasing the number of PCB board feeding and conveying channels and thus increasing the number of PCB boards processed simultaneously. The feeding rack 1 feeds the PCB board from the PCB board feeding port 202 into the work box 201. The cutting component 6 cuts the PCB board inside the work box 201, and the cleaning component 7 cleans the PCB board inside the work box 201. The PCB board is then removed from the work box 201 from the PCB board feeding port 202 and enters the receiving rack 3 for further receiving and unloading. The width of the PCB board feeding and conveying channel can be adjusted by adjusting the horizontal spacing of the two adjacent sets of vertically distributed rotary conveyor belts 501, thus adapting to PCB boards of different widths. The height of the PCB board feeding and conveying channel can be adjusted by adjusting the vertical spacing of the vertically distributed rotary conveyor belts 501, thus adapting to PCB boards of different thicknesses. In the rotary conveyor assembly 5, the support wheels 503 provide rolling support at both ends of the rotary conveyor belt 501, ensuring the normal rotational movement of the rotary conveyor belt 501. The drive wheel assembly 8 provides the driving force for the rotational movement of the rotary conveyor belt 501. The drive frame 801 supports the drive wheel 802, the auxiliary wheel 803, and the tension wheel assembly 807. The drive wheel 802 and the auxiliary wheel 803 cooperate to provide rolling support for the rotary conveyor belt 501. The drive motor 804 drives the drive wheel 802 to rotate through the transmission rod 805. The driving wheel 802 drives the rotary conveyor belt 501 to rotate. The tensioning wheel assembly 807 can adjust the displacement of the tensioning wheel 808, thereby adjusting the tension of the rotary conveyor belt 501. The auxiliary wheel 803 and the tensioning wheel 808 cooperate with the driving wheel 802 to effectively improve the safety and stability of the rotary conveyor belt 501's rotational movement. The first annular groove 809 provides a movement channel for the isolation strip 502 on the outer wall of the auxiliary wheel 803 and the tensioning wheel 808, ensuring the normal rotational conveying movement of the rotary conveyor belt 501. The receiving rack 3 and the feeding rack 1 are designed to have the same structure and are arranged flush with each other, ensuring that the receiving rack 3 and the feeding rack 1 work in the same way and can normally perform clamping and conveying of PCB boards, ensuring the safety and stability of receiving and unloading PCB boards for the pillow; the cutting and cleaning rack 2 is equipped with a dust collection device under the work box 201, which directly performs dust collection on the bottom of the work box 201, ensuring that the cleaned cutting debris is normally discharged from the inside of the work box 201; The vacuum cleaner, drive motor, overhead support structure and height adjustment structure of rotary conveyor assembly 5, and synchronous motion design of the upper and lower rotary conveyor belts 501 in this invention all adopt existing mature structures.

[0024] Please see Figures 1-4 and Figures 9-12The present invention provides a technical solution: a PCB board cutting device with self-cleaning function. The cutting component 6 includes a first support roller 601 and a second support roller 602. The first support roller 601 is disposed above the second support roller 602. A plurality of cutting discs 603 are sleeved on the outer wall of the first support roller 601. The cutting discs 603 are parallel to the center line of the spacing between two adjacent sets of vertically distributed rotary conveyor belts 501. A bracket 604 is provided on the top of the outer wall of the second support roller 602 below the cutting discs 603. The second support roller 602 is fixedly connected to the inner wall of the work box 201. The bracket 604 includes a V-shaped support base 605. Guide wheels 606 are rotatably provided at both ends of the top of the V-shaped support base 605. The guide wheel 606 has a second annular groove 607 at the center of its outer wall that matches the cutting disc 603; the cleaning assembly 7 includes an elastic swing frame 701 symmetrically distributed vertically, a V-shaped frame 702 rotatably provided at the output end of the elastic swing frame 701, and cleaning rollers 703 rotatably provided at both ends of the V-shaped frame 702, with bristles 704 provided on the outer wall of the cleaning rollers 703; the elastic swing frame 701 includes a swing arm 705, one end of which is rotatably connected to a connecting rod 706 at the center of the V-shaped frame 702, and the other end of which is fitted with a rotatably connected support rod 707, with a torsion spring provided between the support rod 707 and the swing arm 705, and the support rod 707 is fixedly connected to the inner wall of the work box 201.

[0025] In one embodiment, the first support roller 601, the second support roller 602, and the guide wheel 606 are parallel to each other. The first support roller 601 is perpendicular to the rotary conveyor belt 501, and the guide wheel 606 is parallel to the drive wheel 802. This ensures that the feeding direction of the PCB board is perpendicular to the first support roller 601 and the second support roller 602, ensuring that the cutting disc 603 can normally cut the PCB board, while also ensuring that the guide wheel 606 can normally provide rolling support for the PCB board.

[0026] In one embodiment, the V-shaped frame 702 is perpendicular to the connecting rod 706, the cleaning roller 703, the connecting rod 706, and the support rod 707 are parallel to each other, and the support rod 707 is perpendicular to the rotary conveyor belt 501. This ensures that the feeding direction of the PCB board is perpendicular to the cleaning roller 703, the connecting rod 706, and the support rod 707, and ensures that the bristles 704 on the cleaning roller 703 can properly clean the PCB board.

[0027] Working principle of the invention: Refer to the attached diagram in the instruction manual. Figures 1-4 and Figures 9-12This invention, through the arrangement of a first support roller 601, a second support roller 602, a cutting disc 603, a bracket 604, an elastic swing frame 701, a V-shaped frame 702, and a cleaning roller 703, provides support for the cutting disc 603 via the first support roller 601 and the bracket 604 via the second support roller 602. After the PCB board enters the work box 201, it moves between the cutting disc 603 and the bracket 604. The bracket 604 provides rolling support for the bottom of the PCB board, while the cutting disc 603 performs cutting processing on the top of the PCB board, ensuring the PCB board... Safety and stability during the cutting process; the elastic swing frame 701 provides elastic swing support for the V-shaped frame 702, the V-shaped frame 702 provides rolling support for the two cleaning rollers 703, the cleaning rollers 703 provide rolling support for the brush bristles 704, and the brush bristles 704 clean the PCB board surface. The two sets of cleaning rollers 703 distributed vertically can clean the upper and lower surfaces of the PCB board simultaneously. Under the support of the elastic swing frame 701, the cleaning rollers 703 and the upper and lower surfaces of the PCB board are in elastic contact during the cleaning process, which can effectively prevent damage to the PCB board during the cleaning process. The V-shaped support base 605 in the bracket 604 provides overhead support for the two guide wheels 606, ensuring that the cutting disc 603 can normally cut the PCB board. The second annular groove 607 provides the movement track of the cutting disc 603 on the outer wall of the guide wheel 606, which can prevent the guide wheel 606 from being damaged while ensuring that the cutting disc 603 can normally cut the PCB board. The swing arm 705 can rotate and support the V-shaped frame 702 via the connecting rod 706, allowing the V-shaped frame 702 to self-adjust. This enables the bristles 704 on the outer wall of the two cleaning rollers 703 on the V-shaped frame 702 to make close rolling contact with the upper and lower surfaces of the PCB board, thereby improving the cleaning effect on the PCB board. The design of the support rod 707 and the torsion spring allows the swing arm 705 to elastically swing and support. The elastic swinging motion of the swing arm 705 allows the cleaning rollers 703 to adapt to PCB boards of different thicknesses, while ensuring the close rolling cleaning effect between the bristles 704 on the outer wall of the cleaning rollers 703 and the PCB board. The first support roller 601 can be freely rotated and installed inside the working box 201, or it can be driven by a rotary drive device to make the first support roller 601 rotate actively. It can be selected according to actual needs. The material of the 704 brush bristles, the elasticity of the torsion spring, and other parameters can all be adjusted and set according to actual conditions to avoid damage to the PCB board during the cleaning process. The cutting disc 603 and the first support roller 601 in this invention both adopt existing mature conventional structural components and conventional control technologies; the above content is common knowledge in the field and is not an improvement of this invention, therefore, it has not been explained in detail.

[0028] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
