Description

Technical Field

[0001] This invention relates to the field of LED lamp production equipment technology, specifically to an LED circuit board cutting device and its usage method. Background Technology

[0002] In the LED light production process, PCB splitting equipment is needed to cut LED light boards into strips. PCB splitting equipment is a type of equipment used to cut large LED light boards into smaller strips that meet the requirements.

[0003] A search revealed that the invention patent with publication number CN104162903B discloses an LED circuit board cutting machine. It uses a cutting device with adjustable height. When cutting LED light boards, the LED light board is placed on the cutting base. The cutting device is driven by a servo motor to slide left and right along the slide rail, so that the cutting blade on the cutting device slides along the cutting base to cut the LED light board.

[0004] The above solution cannot cut LED circuit boards into strips of different widths. After cutting, all of them are collected together, which cannot accommodate the collection of LED circuit boards of different widths, thus limiting its use. Summary of the Invention

[0005] The purpose of this invention is to provide an LED circuit board cutting device and its usage method. LED circuit board strips cut from both sides are positioned by limiting blocks. Initially, both the upper and lower collection frames are located below the end of the feeding belt. The middle LED circuit board strip lacks restraint. When the transfer frame reaches the end of the feeding belt and continues to rotate, the wider LED circuit board strip, lacking positioning restraint, falls into the upper collection frame. Meanwhile, the shorter LED circuit board strip, with mounting restraint, reaches the lower collection frame, where the two limiting blocks open, allowing the shorter strip to be collected. This method enables the collection of LED circuit board strips of different widths. Afterward, the upper collection frame slides on the first discharge belt, while the lower collection frame slides on the second discharge belt. During discharge, a rotary motor drives the corresponding collection frame to rotate, facilitating the tilting and removal of the LED circuit board strips from the collection frame, thus facilitating further processing of the LED circuit board strips and solving the problems mentioned in the background art.

[0006] This invention can be achieved through the following technical solution: an LED circuit board cutting device, comprising a feeding belt, a cutting frame mounted on the edge of the feeding belt, multiple transfer frames for carrying LED circuit boards evenly distributed on the surface of the feeding belt, a rolling cutting component for cutting LED circuit boards inside the cutting frame, and an output belt one and an output belt two respectively provided at the end of the feeding belt, the output belt two being located directly below the feeding belt, and the output belt one being located below the end of the feeding belt, a collection component one being mounted on the surface of the output belt one near the end of the feeding belt, and a collection component two being mounted on the surface of the output belt two near the end of the feeding belt, the collection component one and the collection component two having the same structure, the collection component two including a supporting base plate, the end of the supporting base plate being rotatably connected to a collection frame via a rotary motor, the two collection frames being used to carry LED circuit boards of different widths respectively.

[0007] A further technical improvement of the present invention is that: three bottom grooves are evenly distributed on the bottom surface of the inner cavity of the transfer frame, and two limiting blocks for pressing the top edge and side of the LED circuit board are installed on the inner wall of the transfer frame by a bidirectional cylinder. The limiting blocks are configured as L-shaped structures, and the L-shaped end face of the limiting blocks is provided with an upward inclined surface.

[0008] A further technical improvement of the present invention is that: an electric push rod is installed on the top surface of the inner cavity of the cutting frame, and a negative pressure dust removal box is installed above the cutting frame; an installation plate is installed on the pushing end of the electric push rod; a connecting plate is provided below the installation plate; a pressure pad that fits against the top surface of the LED circuit board is provided on the bottom surface of the connecting plate; and a spring is provided between the connecting plate and the installation plate; and the rolling cutting assembly is installed on the bottom surface of the installation plate.

[0009] A further technical improvement of the present invention is that: the rolling cutting assembly includes a longitudinal linear guide rail mounted on the bottom surface of the mounting plate, a longitudinal slide block is slidably connected to the outside of the longitudinal linear guide rail, a transverse linear guide rail is fixed to the bottom surface of the longitudinal slide block, a transverse slide block is slidably connected to the outside of the transverse linear guide rail, a wheel driven by a servo motor is mounted on the bottom surface of the transverse slide block, and a dust collection cover for collecting cutting dust is provided above the wheel block.

[0010] A further technical improvement of the present invention is that: the middle part of the connecting plate is provided with a through groove, and three extension grooves for the wheel to pass through are provided at equal intervals on both sides of the through groove.

[0011] A further technical improvement of the present invention is that: an exhaust port is provided in the middle of the top surface of the dust collection hood, a dust exhaust pipe is installed at the end of the exhaust port, a telescopic hose is connected to the end of the dust exhaust pipe, and the end of the telescopic hose passes through the mounting plate and extends to the air inlet of the negative pressure dust collection box.

[0012] A further technical improvement of the present invention is that: a retention groove for the dust exhaust pipe to enter is provided on the side of the transverse slide, a second spring is installed in the cavity of the inner wall of the retention groove, an arched pressure block is fixed to the end of the second spring, and the arc-shaped surface of the arched pressure block is pressed against the outer surface of the dust exhaust pipe.

[0013] The present invention also provides a method of using an LED circuit board cutting device, the method specifically including the following steps:

[0014] Step 1: The LED circuit boards are loaded into the transfer frame in sequence, and two limiting blocks are pushed by the bidirectional cylinder to fix the sides and top edges of the LED circuit boards. The boards are then cut as they reach the cutting frame with the feeding belt.

[0015] Step 2: Due to the obstruction of the dust collection hood, the dust and waste generated during cutting are located inside the dust collection hood. They flow through the exhaust port and are guided into the negative pressure dust collection box through the dust exhaust pipe and the telescopic hose.

[0016] Step 3: After being cut, the LED circuit boards are conveyed to the end position by the feeding belt. The middle LED circuit board falls into the collection frame in the first collection component, while the two LED circuit boards pressed together by the limiting pressure block fall into the collection frame in the second collection component, thus realizing the collection of two different widths of LED circuit boards after cutting.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The LED circuit board strips cut on both sides are pressed and positioned by limiting blocks. In the initial state, both the upper and lower collection frames are located below the end of the feeding belt. The LED circuit board strips in the middle are unrestricted. When the transfer frame reaches the end of the feeding belt and continues to rotate, the wider LED circuit board strips that are unrestricted fall into the upper collection frame. The shorter LED circuit board strips that are restricted and have a lower width fall into the lower collection frame when they reach the lower collection frame. The two limiting blocks open, and the shorter LED circuit board strips are collected by the lower collection frame. In this way, the collection of LED circuit board strips of two different widths is achieved. Afterward, the upper collection frame slides on the first discharge belt to discharge the LED circuit board strips, while the lower collection frame slides on the second discharge belt to discharge the LED circuit board strips. During discharge, the corresponding collection frame is rotated by a rotary motor to facilitate tilting and removing the LED circuit board strips in the collection frame, which is convenient for the LED circuit board strips to be processed again.

[0019] 2. The pressure pad re-contacts and fixes the LED circuit board, causing the spring to deform. At this time, the gap between the mounting plate and the connecting plate becomes shorter. The wheel connected to the servo motor passes through the through groove and slides on the horizontal linear guide rail via the horizontal slide block, driving the wheel to cut the LED circuit board along the bottom groove opening. After cutting one section of the LED circuit board, the vertical slide block slides on the vertical linear guide rail to facilitate the cutting of another section of the LED circuit board, resulting in three sections of LED circuit board. The dust and waste generated during cutting are shielded by the dust collection cover.

[0020] 3. The end of the arched pressure block enters the cavity of the retention groove until the dust exhaust pipe reaches the end of the retention groove. Spring 2 returns to its original deformation, the end of the arched pressure block resets and abuts against the outer surface of the dust exhaust pipe. During dust discharge, dust and waste enter through the exhaust port and are guided into the negative pressure dust removal box along the dust exhaust pipe and the telescopic hose. The dust and waste generated during cutting are removed online in real time, with good effect. Attached Figure Description

[0029] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the following detailed description of the specific implementation methods, structures, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0030] Please see Figures 1-6As shown, this invention provides an LED circuit board cutting device, including a feeding belt 1, a cutting frame 3 mounted on the edge of the feeding belt 1, and multiple transfer frames 2 for carrying LED circuit boards evenly distributed on the surface of the feeding belt 1. The cutting frame 3 has a rolling cutting component for cutting the LED circuit boards inside. The ends of the feeding belt 1 are respectively provided with an exit belt 5 and an exit belt 7, with the exit belt 7 located directly below the feeding belt 1 and the exit belt 5 located below the end of the feeding belt 1. A collecting component 6 is mounted on the surface of the exit belt 5 near the end of the feeding belt 1, and a collecting component 8 is mounted on the surface of the exit belt 7 near the end of the feeding belt 1. The collecting components 6 and 8 have the same structure. The collecting component 8 includes a supporting base plate 10, and a collecting frame 9 is rotatably connected to the end of the supporting base plate 10 via a rotary motor. The two collecting frames 9 are used to carry LED circuit boards of different widths, with sufficient gap between the upper collecting frame 9 and the bottom surface of the feeding belt 1. The LED circuit board strips are fed into the transfer frame 2 and cut into strips in the area of ​​the cutting frame 3. The LED circuit board strips cut on both sides are pressed and positioned by the limiting blocks 30. In the initial state, both the upper and lower collection frames 9 are located below the end of the feeding belt 1. The LED circuit board strips in the middle are unrestricted. When the transfer frame 2 reaches the end of the feeding belt 1 and continues to rotate, the LED circuit board strips that are unrestricted and wider fall into the upper collection frame 9. The LED circuit board strips that are restricted and shorter in width, when they reach the position of the lower collection frame 9, the two limiting blocks 30 open, and the shorter LED circuit board strips are collected by the lower collection frame 9. In this way, the collection of LED circuit board strips of two different widths is achieved. Afterwards, the upper collection frame 9 slides on the discharge belt 5 to discharge the LED circuit board strips, while the lower collection frame 9 slides on the discharge belt 7 to discharge the LED circuit board strips. During discharge, the corresponding collection frame 9 is driven to rotate by a rotary motor, which makes it easy to tilt and remove the LED circuit board strips in the collection frame 9, which is convenient for the LED circuit board strips to be processed again.

[0031] Three bottom grooves 29 are evenly distributed on the bottom surface of the inner cavity of the transfer frame 2, and two limiting blocks 30 for pressing the top edge and side of the LED circuit board are installed on the inner wall of the transfer frame 2 by a bidirectional cylinder. The limiting blocks 30 are set in an L-shaped structure, and the L-shaped end face of the limiting blocks 30 is provided with an upward slope. The limiting blocks 30 are driven to move closer or further away from each other by the bidirectional cylinder. When the LED circuit board is restricted and installed, the limiting blocks 30 fix the side and top edge of the LED circuit board.

[0032] An electric push rod 11 is installed on the top surface of the inner cavity of the cutting frame 3, and a negative pressure dust collection box 4 is installed above the cutting frame 3. A mounting plate 13 is installed on the pushing end of the electric push rod 11, and a connecting plate 15 is provided below the mounting plate 13. A pressure pad 16 that fits against the top surface of the LED circuit board is provided on the bottom surface of the connecting plate 15, and a spring 14 is provided between the connecting plate 15 and the mounting plate 13. The rolling cutting assembly is installed on the bottom surface of the mounting plate 13. The rolling cutting assembly includes a longitudinal linear guide rail 18 installed on the bottom surface of the mounting plate 13. A longitudinal slide block 19 is slidably connected to the outside of the longitudinal linear guide rail 18. A transverse linear guide rail 20 is fixed to the bottom surface of the longitudinal slide block 19. A transverse slide block 21 is slidably connected to the outside of the transverse linear guide rail 20. A wheel 22 driven by a servo motor is installed on the bottom surface of the transverse slide block 21. A dust collection cover 23 for collecting cutting dust is provided above the wheel 22. A through groove 17 is provided in the middle of the connecting plate 15. Three extension grooves 31 are provided at equal intervals on both sides for the wheel 22 to pass through. The extension grooves 31 facilitate the cutting of the LED circuit board edge by the wheel 22, so that the LED circuit board strip is cut off. When cutting the LED circuit board, the electric push rod 11 pushes the mounting plate 13 and the connecting plate 15 downward at the same time, and the pressure pad 16 contacts and fixes the LED circuit board again, so that the spring 14 deforms. At this time, the gap between the mounting plate 13 and the connecting plate 15 becomes shorter. At this time, the wheel 22 connected to the servo motor passes through the through groove 17 and slides on the horizontal linear guide rail 20 through the horizontal slide 21, driving the wheel 22 to cut the LED circuit board along the bottom groove 29, cutting one section of the LED circuit board strip. Then, the vertical slide 19 slides on the vertical linear guide rail 18 to facilitate the cutting of another section of the LED circuit board strip, resulting in three sections of LED circuit board strip. The dust and waste generated during cutting are shielded by the dust collection cover 23.

[0033] The top surface of the dust collection hood 23 has an exhaust port 24 in the middle. A dust exhaust pipe 25 is connected to the end of the exhaust port 24. A flexible hose 12 is connected to the end of the dust exhaust pipe 25. The end of the flexible hose 12 passes through the mounting plate 13 and extends to the air inlet of the negative pressure dust collector 4. A retention groove 26 for the dust exhaust pipe 25 is provided on the side of the transverse slide 21. A second spring 28 is installed in the cavity of the inner wall of the retention groove 26. An arched pressure block 27 is fixed to the end of the second spring 28. The arc-shaped surface of the arched pressure block 27 presses against the outer surface of the dust exhaust pipe 25, and the negative pressure dust collector 4 begins to... During operation, the dust exhaust pipe 25 is threaded onto the exhaust port 24, and the dust exhaust pipe 25 is inserted into the retention groove 26. The dust exhaust pipe 25 presses against the two arched pressure blocks 27 and squeezes the second spring 28. At this time, the end of the arched pressure block 27 enters the cavity of the retention groove 26 until the dust exhaust pipe 25 reaches the end of the retention groove 26. The second spring 28 returns to its original shape, and the end of the arched pressure block 27 returns to its original position and abuts against the outer surface of the dust exhaust pipe 25. During dust discharge, dust and waste enter through the exhaust port 24 and are guided by the dust exhaust pipe 25 and the telescopic hose 12 into the negative pressure dust collector 4.

[0034] The present invention also provides a method of using an LED circuit board cutting device, the method specifically including the following steps:

[0035] Step 1: The LED circuit boards are sequentially loaded into the transfer frame 2, and the two limiting blocks 30 are pushed by the bidirectional cylinder to fix the sides and top edges of the LED circuit boards. As the feeding belt 1 arrives at the cutting frame 3, the LED circuit boards are cut.

[0036] Step 2: Due to the obstruction of the dust collection hood 23, the dust and waste generated during cutting are located inside the dust collection hood 23. They are then transported through the exhaust port 24 and guided by the dust exhaust pipe 25 and the telescopic hose 12 into the negative pressure dust collection box 4.

[0037] Step 3: After being cut, the LED circuit boards are driven to the end position by the feeding belt 1. The middle LED circuit board falls into the collection frame 9 in the collection component 1 6, while the two LED circuit boards pressed together by the limiting pressure block 30 fall into the collection frame 9 in the collection component 2 8, thus realizing the collection of two different width LED circuit boards after cutting.

[0038] In use, the LED circuit board strips cut on both sides are pressed and positioned by the limiting pressure block 30. In the initial state, both the upper and lower collection frames 9 are located below the end of the feeding belt 1. The LED circuit board strip in the middle lacks restraint. When the transfer frame 2 reaches the end of the feeding belt 1 and continues to rotate, the LED circuit board strip that lacks positioning restraint and is wider falls into the upper collection frame 9. However, when the LED circuit board strip that has installation restraint and is shorter reaches the position of the lower collection frame 9, the two limiting pressure blocks 30 open, and the shorter LED circuit board strip is collected by the lower collection frame 9. In this way, the collection of two LED circuit board strips of different widths is achieved. Afterward, the upper collection frame 9 slides on the discharge belt 5 to discharge the LED circuit board strip, while the lower collection frame 9 slides on the discharge belt 7 to discharge the LED circuit board strip. During discharge, the corresponding collection frame 9 is driven to rotate by a rotary motor, which facilitates tilting and removing the LED circuit board strip in the collection frame 9, making it convenient for the LED circuit board strip to be processed again.

[0039] The LED circuit board is re-contacted and fixed by the pressure pad 16, causing the spring 14 to deform. At this time, the gap between the mounting plate 13 and the connecting plate 15 becomes shorter. The wheel 22 connected to the servo motor passes through the through groove 17 and slides on the horizontal linear guide rail 20 through the horizontal slide block 21, driving the wheel 22 to cut the LED circuit board along the bottom groove 29, cutting a section of LED circuit board. Then, the vertical slide block 19 slides on the vertical linear guide rail 18 to facilitate the cutting of another section of LED circuit board, resulting in three sections of LED circuit board. The dust and debris generated during cutting are shielded by the dust collection cover 23.

[0040] The end of the arched pressure block 27 enters the cavity of the retention groove 26 until the dust exhaust pipe 25 reaches the end of the retention groove 26. The spring 28 returns to its original shape, the end of the arched pressure block 27 resets and abuts against the outer surface of the dust exhaust pipe 25. During dust discharge, dust and waste enter through the exhaust port 24 and are guided by the dust exhaust pipe 25 and the telescopic hose 12 into the negative pressure dust removal box 4. The dust and waste generated during cutting are removed online in real time, with good effect.

[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
