Description

Technical Field

[0001] This invention relates to the field of FPC circuit board processing, and more specifically, to the process flow of flexible printed circuit boards. Background Technology

[0002] PCB (Printed Circuit Board) is a type of printed circuit board, often referred to as a rigid board. FPC (Flexible Printed Circuit) is a type of flexible circuit board, also known as a flexible circuit board or flexographic board. Miniaturization of electronic products is an inevitable trend, and for a significant portion of consumer products, surface mount technology (SMD) is mounted on FPCs to complete the assembly of the entire device due to space constraints. FPCs are widely used in digital products such as calculators, mobile phones, digital cameras, and digital camcorders. Surface mount technology (SMD) on FPCs has become one of the development trends in SMT (Surface Mount Technology).

[0003] When processing FPCs, they need to be fixed in place. When they are placed on a carrier board, the dust on the carrier board needs to be cleaned manually, which is quite troublesome. In addition, during solder paste printing, splatter may fly everywhere, affecting the processing environment. Therefore, we propose a flexible printed circuit board process flow.

[0010] Preferably, the pull plate is inclined about the first slider, the first pull plate is offset from the center of the first turntable, and the flip plate forms a rotating structure through the first turntable.

[0011] Preferably, the adjustment mechanism includes a second turntable, a push plate, a connecting rod, a connecting block, a second slide rod, a second connecting plate, and a cutting equipment body. The second turntable is rotatably connected to the top of the mounting platform. A push plate is rotatably connected to the surface of the second turntable. A connecting rod is rotatably connected to the surface of the push plate. A connecting block is rotatably connected to the surface of the connecting rod. A second slide rod is fixedly connected to the surface of the connecting block. A second connecting plate is slidably connected to the surface of the second slide rod. The cutting equipment body is mounted on the bottom of the second connecting plate.

[0012] Preferably, the push plate is disposed on the vertical central axis of the second turntable, the length of the push plate is greater than the diameter of the second turntable, and the push plate and the connecting rod are arranged to cross each other.

[0013] Preferably, the second slide rod is perpendicular to the connecting block, the second slide rod is embedded in the vertical slide rail on the surface of the second connecting plate and is slidably connected to it, and the surface of the mounting platform is provided with a transverse buffer groove.

[0014] Preferably, the cleaning mechanism includes a rotating plate, an embedded rod, a third connecting plate, a groove, a second slider, a movable plate, a control plate, and a cleaning roller. The rotating plate is rotatably connected to the surface of the mounting plate. The embedded rod is fixedly connected to the surface of the rotating plate. The third connecting plate is slidably connected to the surface of the embedded rod. The third connecting plate has a groove on its surface. The second slider is fixedly connected to the surface of the third connecting plate. The bottom of the second slider is rotatably connected to the movable plate. The bottom of the movable plate is rotatably connected to the control plate. The bottom of the control plate is provided with a cleaning roller.

[0015] Preferably, the embedded rod is vertically disposed at the left and right ends of the rotating plate, the sliding groove is vertically disposed on the surface of the third connecting plate, the third connecting plate forms a sliding structure through the embedded rod, and the movable plate is symmetrically disposed in two sets in a figure-eight shape about the center point of the control plate, and the ends of the two sets of movable plates are rotatably connected to the control plate.

[0016] This solution also provides a flexible printed circuit board process flow, which includes the following steps:

[0017] S1. First, clean the carrier plate. Turn on the motor to control the second turntable to rotate. Because the embedding rod is vertically set at the two ends of the rotating plate, when the rotating plate rotates, it will drive the embedding rod to slide along the inside of the third connecting plate. The third connecting plate will move to the side through the sliding of the embedding rod. Then, the two sets of second sliders will move accordingly. Because the movable plate is set with two sets in a figure-eight shape, when the two sets of second sliders move away from each other, they will push the control plate, causing the control plate to drive the cleaning roller to move on the carrier plate to remove the dust from the carrier plate. Then, apply high-temperature resistant double-sided tape to the carrier plate, with the same effect as the silicone plate. Then, stick the flexible circuit board to the carrier plate and fix it.

[0018] S2. Next, the conveyor belt will push the flexible circuit board to move. When it moves to the bottom of the printing equipment body, the printing equipment body will print solder paste on it. By setting an optical positioning module, the solder paste printing can be more accurate. In use, by setting a flip plate, it can prevent splashing of solder paste during printing. When the flip plate needs to be opened, just open the hydraulic rod. Then the hydraulic rod will pull the connecting block, and the first slide rod will move accordingly. Because the first slide rod is embedded in the inclined groove inside the force plate, when the first slide rod slides, it will drive the force plate to move away from the mounting plate. Then the first connecting plate that is rotatably connected to it will start to tilt. At this time, the first slider loses the support force of the first connecting plate and rebounds downward under the action of the spring, pulling the pull plate. Because the pull plate is off the center of the first turntable, when the pull plate is pulled downward, it will cause the first turntable to rotate counterclockwise. The flip plate that is fixedly connected to the first turntable will rotate accordingly, realizing the purpose of opening, which makes it convenient for the staff to wipe the inside.

[0019] S3. Finally, after the solder paste printing is completed, the flexible circuit board will be placed and reflowed sequentially through the main body of the placement equipment and the main body of the reflow soldering equipment. Finally, it will be transported to the bottom of the cutting equipment for stamping and cutting. In order to greatly improve the work efficiency and make the edges of the stamped flexible circuit board neat and beautiful, when it is necessary to adjust the angle of the cutting equipment, it is only necessary to drive the second turntable to rotate by the motor. Because the push plate is set on the vertical central axis of the second turntable, when the second turntable rotates counterclockwise, it will apply a pushing force to the left of the push plate. Then the push plate will push the connecting block through the connecting rod. The second slide bar, which is perpendicular to the connecting block, will also move accordingly. Because the second slide bar is embedded in the vertical slide groove in the second connecting plate, when the second slide bar moves, it will drive the second connecting plate to swing. Then the cutting equipment body installed at the bottom of the second connecting plate will also swing accordingly to achieve the adjustment of the angle.

[0020] The flexible printed circuit board process provided by this invention has the following beneficial effects when used:

[0021] 1. The flexible printed circuit board process involves setting up embedding rods. Because the embedding rods are vertically set at the two ends of the rotating plate, when the rotating plate rotates, they will drive the embedding rods to slide along the inside of the third connecting plate. The third connecting plate will move to the side due to the sliding of the embedding rods. Subsequently, the two sets of second sliders will move accordingly. Because the movable plate is set with two sets in a figure-eight shape, when the two sets of second sliders move away from each other, they will push the control plate, causing the control plate to drive the cleaning roller to move on the carrier plate to remove dust from the carrier plate. Then, high-temperature resistant double-sided tape is attached to the carrier plate, with the same effect as silicone plate. Finally, the flexible circuit board is pasted onto the carrier plate to fix it.

[0022] 2. The flexible printed circuit board process, by setting a flip plate, can prevent splatter during solder paste printing. When the flip plate needs to be opened, only the hydraulic rod needs to be opened. Then the hydraulic rod will pull the connecting block, and the first slide rod will move accordingly. Because the first slide rod is embedded in the inclined groove inside the force plate, when the first slide rod slides, it will drive the force plate to move away from the mounting plate. Then the first connecting plate that is rotatably connected to it will begin to tilt.

[0023] 3. In this flexible printed circuit board process, by setting a first connecting plate, when it is tilted, the first slider loses the support of the first connecting plate and rebounds downward under the action of the spring, pulling the pull plate. Because the pull plate is off the center of the first turntable, when the pull plate is subjected to downward pulling force, it will cause the first turntable to rotate counterclockwise. The flip plate fixedly connected to the first turntable will rotate accordingly, realizing the purpose of opening, which makes it convenient for the staff to wipe the inside.

[0024] 4. The flexible printed circuit board process involves setting up a push plate. Because the push plate is located on the vertical central axis of the second turntable, when the second turntable rotates counterclockwise, it will apply a pushing force to the left on the push plate. Subsequently, the push plate will push the connecting block through the connecting rod. The second slide rod, which is perpendicular to the connecting block, will also move accordingly. Because the second slide rod is embedded in the vertical groove inside the second connecting plate, when the second slide rod moves, it will drive the second connecting plate to swing. Subsequently, the main body of the cutting equipment installed at the bottom of the second connecting plate will also swing accordingly, thereby achieving angle adjustment.

All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0038] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0039] Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0040] For examples, please refer to Figures 1 to 9 This embodiment provides a flexible printed circuit board process flow, including a base 1, a conveyor belt 2, a carrier plate 3, a mounting plate 4, and an opening and closing mechanism disposed on the surface of the mounting plate 4. The conveyor belt 2 is disposed on the surface of the base 1, and the carrier plate 3 is fixedly connected to the surface of the conveyor belt 2. The mounting plate 4 is fixedly connected to the surface of the base 1 on the side of the conveyor belt 2. The opening and closing mechanism includes a transmission component and a control component.

[0041] The transmission assembly includes a hydraulic rod 5, a connecting block 6, a first sliding rod 7, and a force-bearing plate 8. The hydraulic rod 5 is fixedly connected to the surface of the mounting plate 4. The output end of the hydraulic rod 5 is fixedly connected to the connecting block 6. The bottom of the connecting block 6 is fixedly connected to the first sliding rod 7. The surface of the first sliding rod 7 is slidably connected to the force-bearing plate 8.

[0042] The control assembly includes a first connecting plate 9, a spring 10, a first slider 11, a pull plate 12, a first turntable 13, and a flip plate 14. The first connecting plate 9 is slidably connected to the side of the force-bearing plate 8. The first slider 11 is rotatably connected to the surface of the first connecting plate 9. The bottom of the first slider 11 is fixedly connected to the spring 10. The side of the first slider 11 is rotatably connected to the pull plate 12. The surface of the pull plate 12 is rotatably connected to the first turntable 13. The surface of the first turntable 13 is rotatably connected to the flip plate 14.

[0043] A printing equipment body 15 is fixedly connected to the surface of the base 1. An optical positioning module 16 is provided on the top of the printing equipment body 15. A patch device body 17 is provided on the side of the printing equipment body 15. A reflow soldering equipment body 18 is provided on the side of the patch device body 17. A mounting platform 19 fixedly connected to the mounting plate 4 is provided on the side of the reflow soldering equipment body 18. An adjustment mechanism 20 is provided on the top of the mounting platform 19. A cleaning mechanism 21 is provided on the surface of the mounting plate 4.

[0044] Furthermore, the first slide rod 7 is vertically set at the bottom of the connecting block 6. The first slide rod 7 is embedded in the inclined slide rail on the surface of the force plate 8 and is slidably connected to it. The force plate 8 forms a left-right sliding structure through the first slide rod 7. Because the first slide rod 7 is embedded in the inclined groove inside the force plate 8, when the first slide rod 7 slides, it will drive the force plate 8 to move away from the mounting plate 4. Subsequently, the first connecting plate 9, which is rotatably connected to it, will begin to tilt.

[0045] Furthermore, the pull plate 12 is inclined about the first slider 11, and the first pull plate 12 is offset from the center of the first turntable 13. The flip plate 14 forms a rotating structure through the first turntable 13. The first slider 11 loses the support of the first connecting plate 9 and rebounds downward under the action of the spring 10, pulling the pull plate 12. Because the pull plate 12 is offset from the center of the first turntable 13, when the pull plate 12 is pulled downward, it will cause the first turntable 13 to rotate counterclockwise. The flip plate 14, which is fixedly connected to the first turntable 13, will rotate accordingly, thus achieving the purpose of opening and making it convenient for staff to wipe the inside.

[0046] Furthermore, the adjustment mechanism 20 includes a second turntable 2001, a push plate 2002, a connecting rod 2003, a connecting block 2004, a second slide rod 2005, a second connecting plate 2006, and a cutting equipment body 2007. The second turntable 2001 is rotatably connected to the top of the mounting platform 19. The push plate 2002 is rotatably connected to the surface of the second turntable 2001. The connecting rod 2003 is rotatably connected to the surface of the push plate 2002. The connecting block 2004 is rotatably connected to the surface of the connecting rod 2003. The second slide rod 2005 is fixedly connected to the surface of the connecting block 2004. The second connecting plate 2006 is slidably connected to the surface of the second slide rod 2005. The cutting equipment body 2007 is installed at the bottom of the second connecting plate 2006. By setting the adjustment mechanism 20, the angle of the cutting equipment body 2007 can be adjusted, which greatly improves the work efficiency, and at the same time, the edges of the punched flexible circuit board are neat and beautiful.

[0047] Furthermore, the push plate 2002 is positioned on the vertical central axis of the second turntable 2001. The length of the push plate 2002 is greater than the diameter of the second turntable 2001. The push plate 2002 and the connecting rod 2003 are arranged to cross each other. Because the push plate 2002 is positioned on the vertical central axis of the second turntable 2001, when the second turntable 2001 rotates counterclockwise, it will apply a pushing force to the left on the push plate 2002. Subsequently, the push plate 2002 will push the connecting block 2004 through the connecting rod 2003, and the second slide rod 2005, which is perpendicular to the connecting block 2004, will also move accordingly.

[0048] Furthermore, the second slide rod 2005 is perpendicular to the connecting block 2004. The second slide rod 2005 is embedded in the vertical slide rail on the surface of the second connecting plate 2006 and is slidably connected to it. The surface of the mounting platform 19 is provided with a horizontal buffer groove. Because the second slide rod 2005 is embedded in the vertical slide rail in the second connecting plate 2006, when the second slide rod 2005 moves, it will drive the second connecting plate 2006 to swing. Subsequently, the cutting equipment body 2007 installed at the bottom of the second connecting plate 2006 will also swing accordingly, thereby realizing the adjustment of the angle.

[0049] Furthermore, the cleaning mechanism 21 includes a rotating plate 2101, an embedded rod 2102, a third connecting plate 2103, a groove 2104, a second slider 2105, a movable plate 2106, a control plate 2107, and a cleaning roller 2108. The rotating plate 2101 is rotatably connected to the surface of the mounting plate 4. The embedded rod 2102 is fixedly connected to the surface of the rotating plate 2101. The third connecting plate 2103 is slidably connected to the surface of the embedded rod 2102. The groove 2104 is provided on the surface of the third connecting plate 2103. The second slider 2105 is fixedly connected to the surface of the third connecting plate 2103. The movable plate 2106 is rotatably connected to the bottom of the second slider 2105. The control plate 2107 is rotatably connected to the bottom of the movable plate 2106. The cleaning roller 2108 is provided at the bottom of the control plate 2107. By setting up the cleaning mechanism 21, dust and foreign objects such as solder beads on the surface of the carrier plate 3 can be removed.

[0050] Furthermore, the embedded rod 2102 is vertically disposed at the left and right ends of the rotating plate 2101, and the slide groove 2104 is vertically disposed on the surface of the third connecting plate 2103. The third connecting plate 2103 forms a sliding structure through the embedded rod 2102. The movable plate 2106 is symmetrically disposed in two sets in a figure-eight shape about the center point of the control plate 2107. The ends of the two sets of movable plates 2106 are rotatably connected to the control plate 2107. When the rotating plate 2101 rotates, it will drive the embedded rod 2102 to move along the interior of the third connecting plate 2103. Sliding, the third connecting plate 2103 will move to the side through the sliding of the embedded rod 2102, and then the two sets of second sliders 2105 will move accordingly. Because the movable plate 2106 is provided with two sets in a figure-eight shape, when the two sets of second sliders 2105 move away from each other, they will push the control plate 2107, so that the control plate 2107 drives the cleaning roller 2108 to move on the carrier plate 3, removing the dust on the carrier plate 3. Then, high temperature resistant double-sided tape is attached to the carrier plate 3, with the same effect as the silicone plate. Then, the flexible circuit board is attached to the carrier plate 3 to fix it.

[0051] This solution also provides a flexible printed circuit board process flow, which includes the following steps:

[0052] S1. First, clean the carrier plate 3. Turn on the motor to control the second turntable 2001 to rotate. Since the embedded rod 2102 is vertically set at the two ends of the rotating plate 2101, when the rotating plate 2101 rotates, it will drive the embedded rod 2102 to slide along the inside of the third connecting plate 2103. The third connecting plate 2103 will move to the side through the sliding of the embedded rod 2102. Then, the two sets of second sliders 2105 move accordingly. Since the movable plate 2106 is set with two sets in a figure-eight shape, when the two sets of second sliders 2105 move away from each other, it will push the control plate 2107, so that the control plate 2107 drives the cleaning roller 2108 to move on the carrier plate 3 to remove the dust on the carrier plate 3. Then, apply high temperature resistant double-sided tape to the carrier plate 3. The effect is the same as that of the silicone plate. Then, stick the flexible circuit board to the carrier plate 3 to fix it.

[0053] S2. Next, the conveyor belt 2 will push the flexible circuit board to move. When it moves to the bottom of the printing equipment body 15, the printing equipment body 15 will print solder paste on it. By setting the optical positioning module 16, the solder paste printing can be made more accurate. In use, by setting the flip plate 14, splashing can be prevented during solder paste printing. When the flip plate 14 needs to be opened, only the hydraulic rod 5 needs to be opened. Then the hydraulic rod 5 will pull the connecting block 6, and the first slide rod 7 will move accordingly. Because the first slide rod 7 is embedded in the inclined groove inside the force plate 8, in When the first sliding rod 7 slides, it will drive the force plate 8 to move away from the mounting plate 4. Then the first connecting plate 9, which is rotatably connected to it, will start to tilt. At this time, the first slider 11 loses the support of the first connecting plate 9 and rebounds downward under the action of the spring 10, pulling the pull plate 12. Because the pull plate 12 is off the center of the first turntable 13, when the pull plate 12 is pulled downward, it will cause the first turntable 13 to rotate counterclockwise. The flip plate 14, which is fixedly connected to the first turntable 13, will rotate accordingly, so as to open the door and make it easier for the staff to wipe the inside.

[0054] S3. Finally, after the solder paste printing is completed, the flexible circuit board will undergo placement and reflow soldering operations sequentially through the placement equipment body 17 and the reflow soldering equipment body 18. Finally, it will be transported to the bottom of the cutting equipment body 2007 for stamping and cutting. To significantly improve work efficiency and ensure the stamped flexible circuit board has neat and aesthetically pleasing edges, when the angle of the cutting equipment body 2007 needs to be adjusted, it is only necessary to rotate the second turntable 2001 via a motor. This is because the push plate 2002 is located on the vertical central axis of the second turntable 2001. When 001 rotates counterclockwise, it applies a pushing force to the left on the push plate 2002. Then, the push plate 2002 pushes the connecting block 2004 through the connecting rod 2003. The second slide rod 2005, which is perpendicular to the connecting block 2004, also moves accordingly. Because the second slide rod 2005 is embedded in the vertical groove in the second connecting plate 2006, when the second slide rod 2005 moves, it will cause the second connecting plate 2006 to swing. Then, the cutting equipment body 2007 installed at the bottom of the second connecting plate 2006 will also swing accordingly, thereby adjusting the angle.

[0055] like Figure 1 As shown, the flexible printed circuit board process involves the following steps: First, the carrier board 3 is cleaned. Then, the motor is turned on to control the second turntable 2001 to rotate. Because the embedded rod 2102 is vertically positioned at both ends of the rotating plate 2101, the rotating plate 2101 rotates, causing the embedded rod 2102 to slide along the interior of the third connecting plate 2103. The third connecting plate 2103 moves laterally due to the sliding of the embedded rod 2102. Subsequently, the two sets of second sliders 2105 move accordingly. Because the movable plate 2106 has two sets arranged in a figure-eight shape, when the two sets of second sliders 2105 move away from each other, they push the control plate 2107, causing the control plate 2107 to drive the cleaning roller 2108 to move on the carrier board 3, removing dust from the carrier board 3. Then, high-temperature resistant double-sided tape is applied to the carrier board 3, achieving the same effect as a silicone plate. Finally, the flexible circuit board is pasted onto the carrier board 3 to fix it in place.

[0056] Subsequently, the conveyor belt 2 pushes the flexible circuit board to move. When it moves to the bottom of the printing equipment body 15, the printing equipment body 15 will print solder paste on it. By setting the optical positioning module 16, the solder paste printing can be made more accurate. In use, by setting the flip plate 14, it can prevent splashing of solder paste during printing. When it is necessary to open the flip plate 14, simply open the hydraulic rod 5. Then the hydraulic rod 5 will pull the connecting block 6, and the first sliding rod 7 will move accordingly. Because the first sliding rod 7 is embedded in the inclined groove inside the force plate 8, the first sliding rod 7 moves accordingly. When rod 7 slides, it will cause the force plate 8 to move away from the mounting plate 4. Then the first connecting plate 9, which is rotatably connected to it, will start to tilt. At this time, the first slider 11 loses the support of the first connecting plate 9 and rebounds downward under the action of spring 10, pulling the pull plate 12. Because the pull plate 12 is off the center of the first turntable 13, when the pull plate 12 is pulled downward, it will cause the first turntable 13 to rotate counterclockwise. The flip plate 14, which is fixedly connected to the first turntable 13, will rotate accordingly, so as to open the door and make it easier for the staff to wipe the inside.

[0057] After solder paste printing is completed, the flexible circuit board will undergo placement and reflow soldering operations sequentially through the placement equipment body 17 and the reflow soldering equipment body 18. Finally, it will be transported to the bottom of the cutting equipment body 2007 for stamping and cutting. To significantly improve work efficiency and ensure that the edges of the stamped flexible circuit boards are neat and aesthetically pleasing, when the angle of the cutting equipment body 2007 needs to be adjusted, it is only necessary to rotate the second turntable 2001 by driving the motor. This is because the push plate 2002 is set on the vertical central axis of the second turntable 2001. When rotated counterclockwise, a pushing force is applied to the left side of the push plate 2002. Subsequently, the push plate 2002 pushes the connecting block 2004 through the connecting rod 2003. The second slide rod 2005, which is perpendicular to the connecting block 2004, also moves accordingly. Because the second slide rod 2005 is embedded in the vertical groove in the second connecting plate 2006, when the second slide rod 2005 moves, it will cause the second connecting plate 2006 to swing. Subsequently, the cutting equipment body 2007 installed at the bottom of the second connecting plate 2006 will also swing accordingly, thereby achieving angle adjustment.

7. A flexible printed circuit board manufacturing process, using the flexible printed circuit board fabrication apparatus according to any one of claims 1-6, characterized in that, Includes the following steps: S1. First, clean the carrier plate. Turn on the motor to control the rotating plate to rotate. Because the embedded rod is vertically set at the two ends of the rotating plate, when the rotating plate rotates, it will drive the embedded rod to slide along the inside of the third connecting plate. The third connecting plate will move to the side through the sliding of the embedded rod. Then, the two sets of second sliders will move accordingly. Because the movable plate is set with two sets in a figure-eight shape, when the two sets of second sliders move away from each other, they will push the control plate, causing the control plate to drive the cleaning roller to move on the carrier plate to remove the dust from the carrier plate. Then, apply high-temperature resistant double-sided tape to the carrier plate, with the same effect as the silicone plate. Then, stick the flexible circuit board to the carrier plate to fix it. S2. Next, the conveyor belt will push the flexible circuit board to move. When it moves to the bottom of the printing equipment body, the printing equipment body will print solder paste on it. By setting an optical positioning module, the solder paste printing can be more accurate. In use, by setting a flip plate, it can prevent splashing of solder paste during printing. When the flip plate needs to be opened, just open the hydraulic rod. Then the hydraulic rod will pull the connecting block, and the first slide rod will move accordingly. Because the first slide rod is embedded in the inclined groove inside the force plate, when the first slide rod slides, it will drive the force plate to move away from the mounting plate. Then the first connecting plate that is rotatably connected to it will start to tilt. At this time, the first slider loses the support force of the first connecting plate and rebounds downward under the action of the spring, pulling the pull plate. Because the pull plate is off the center of the first turntable, when the pull plate is pulled downward, it will cause the first turntable to rotate counterclockwise. The flip plate that is fixedly connected to the first turntable will rotate accordingly, realizing the purpose of opening, which makes it convenient for the staff to wipe the inside. S3. Finally, after the solder paste printing is completed, the flexible circuit board will be placed and reflowed sequentially through the main body of the placement equipment and the main body of the reflow soldering equipment. Finally, it will be transported to the bottom of the cutting equipment for stamping and cutting. In order to greatly improve the work efficiency and make the edges of the stamped flexible circuit board neat and beautiful, when it is necessary to adjust the angle of the cutting equipment, it is only necessary to drive the second turntable to rotate by the motor. Because the push plate is set on the vertical central axis of the second turntable, when the second turntable rotates counterclockwise, it will apply a pushing force to the left of the push plate. Then the push plate will push the connecting block through the connecting rod. The second slide bar, which is perpendicular to the connecting block, will also move accordingly. Because the second slide bar is embedded in the vertical slide groove in the second connecting plate, when the second slide bar moves, it will drive the second connecting plate to swing. Then the cutting equipment body installed at the bottom of the second connecting plate will also swing accordingly to achieve the adjustment of the angle.
