Description

Technical Field

[0001] This invention belongs to the field of circuit board processing technology, specifically a circuit board processing integrated cutting and punching processing equipment and its processing method. Background Technology

[0002] Circuit board (PCB) cutting and punching is a common processing method in PCB manufacturing. This method is mainly used to create holes, cut, and separate different functional areas on PCBs to meet the needs of PCB wiring and component mounting. Integrated cutting and punching equipment typically consists of CNC machine tools, cutting tools, drills, and other components. Cutting involves using a rotating cutting tool to cut the PCB material into the required shape and size, while punching uses impact force to pierce the PCB material. These processes require precise control and adjustment to ensure processing quality and efficiency. To improve processing efficiency, cutting and punching operations are often performed simultaneously in PCB manufacturing, and this is generally accomplished using an integrated cutting and punching machine.

[0003] To prevent circuit boards from shifting during cutting and punching, affecting cutting and punching accuracy, clamps are often used to hold the circuit boards. Conventional clamps mainly consist of two close-to-each clamping plates and a base plate. The circuit board is fixed by clamping it between the two clamping plates. After fixing, it is sent to the cutting and punching machine for cutting and punching. During cutting, the base plate of this type of clamp can effectively support and fix the circuit board. However, during punching, the presence of the base plate makes it easy for the drill bit to come into contact with the base plate, which not only affects the service life of the drill bit but also the service life of the clamp. It is urgent to improve the clamping part to adapt to the clamping requirements of cutting and drilling.

[0004] When cutting and punching circuit boards, the circuit boards need to be fixed to the fixture before subsequent processing can be carried out. This means that each circuit board needs to be manually fixed during processing, and then removed from the fixture for unloading. The whole process requires the assistance of operators, which not only increases the labor intensity, but also poses uncertain safety risks and significant safety hazards due to manual operation. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated cutting and punching processing equipment and method for circuit board processing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated cutting and punching processing equipment for circuit board processing, comprising a base plate, wherein reinforcing ribs are fixedly installed at equal angles on the outer side of the base plate, and an annular guide rail is provided on the outer side of the base plate, the other end of the reinforcing ribs being connected to the inner side of the annular guide rail; three worktables are provided at equal angles above the base plate, and each worktable has a guide block fixedly installed at its bottom end near the outer side; the worktable is movably engaged with the annular guide rail via the guide block, the guide block rotating relative to the annular guide rail, and the end of the worktable away from the guide block... Each component is equipped with a support frame. A base is provided at one end of the outer side of the annular guide rail. A cutting and punching integrated machine is fixedly installed on the top of the base. The cutting and punching integrated machine is located directly above a workbench on one side. A support platform is provided in the middle of the top of the workbench. A main cylinder is fixedly installed in the middle of the workbench. The output end of the main cylinder is connected to the middle of the bottom of the support platform. Mounting frames are installed on both the left and right sides of the top of the workbench. Transverse guide rails are installed on the front and rear sides of the inner side of the top of the mounting frame. A clamping assembly is provided between the front and rear transverse guide rails. Auxiliary support assemblies are installed on both the front and rear sides of the support platform.

[0007] Before actual use, the three workbenches must be aligned with the feeding conveyor belt, the discharging conveyor belt, and the cutting and punching machine, respectively. It is also necessary to ensure that each workbench can be aligned with the feeding conveyor belt, the discharging conveyor belt, and the cutting and punching machine after being rotated 120 degrees. At the same time, the cutting and punching machine can perform linear cutting and punching operations on the circuit board.

[0008] As a further technical solution of the present invention, a motor is fixedly installed at the middle of the top of the base plate, and a cam divider is provided at the top of the motor. The input end of the cam divider is connected to the output end of the motor. A connecting plate is provided between the three support frames, and the three support frames are equally angled on the outer side of the connecting plate and connected to the outer side of the connecting plate. The output shaft of the cam divider is connected to the bottom end of the connecting plate, and the single rotation angle of the cam divider is 120 degrees.

[0009] When in use, power can be input to the cam divider by turning on the motor, and the cam divider will drive the top worktable to rotate circumferentially. The angle of the worktable rotating once is exactly 120 degrees, and it corresponds to the feeding conveyor belt, the discharging conveyor belt and the cutting and punching integrated machine.

[0010] As a further technical solution of the present invention, the clamping assembly includes an extension rod, which is connected to the side of the support platform. A second fixing seat is fixedly connected to the end of the extension rod away from the support platform. The clamping assembly also includes a locking block, which is movably engaged with the transverse guide rail and can move left and right relative to the transverse guide rail.

[0011] As a further technical solution of the present invention, a connecting frame is installed at the top of each pair of the card blocks, and a clamping plate is installed at the end of the connecting frame away from the mounting frame. The inner side of the clamping plate is provided with an anti-slip groove.

[0012] As a further technical solution of the present invention, each of the card blocks is equipped with a first fixed seat at its bottom end. The end of the first fixed seat away from the card block is movably connected to a connecting rod via a rotating shaft. The end of the connecting rod away from the first fixed seat is movably connected to a second fixed seat via a rotating shaft.

[0013] When processing circuit boards, the feeding conveyor belt can transport a single circuit board to the top of the worktable. At this time, the circuit board is directly above the support platform. When the bottom of the circuit board contacts the top of the support platform, the main cylinder can be activated to drive the support platform to move downward. When the support platform moves downward, a force can be applied to the connecting rods, and multiple connecting rods deflect inward. At this time, the angle between the connecting rods and the extension rods decreases, and a pulling force is applied to the clamping block, which drives the clamping block to move relative to the lateral guide rail. Finally, the left and right clamping plates move closer together until the clamping plates contact the side of the circuit board, completing the clamping process of the circuit board.

[0014] By utilizing the vertical displacement of the support platform, the circuit boards from the feed conveyor can be connected and discharged when the support platform is at a high point, while the circuit boards can be automatically clamped when the support platform is at a low point. The entire process is completed quickly, and the clamping and loosening of the circuit boards can be completed quickly without repeated manual adjustments. This can shorten the fixing time of the circuit boards during processing and improve processing efficiency.

[0015] As a further technical solution of the present invention, the auxiliary support component includes a longitudinal guide rail, which is connected to the end face of the support platform. A longitudinal movable block is movably engaged inside the longitudinal guide rail. The longitudinal movable block moves up and down relative to the longitudinal guide rail. An installation block is fixedly installed on the side of the longitudinal movable block away from the support platform. A vacuum suction cup is installed on the top of each installation block.

[0016] As a further technical solution of the present invention, a mounting plate is fixedly installed on the side of the longitudinal movable block away from the mounting block, a limit telescopic rod is fixedly installed on the side of the mounting plate close to the mounting block, and a return spring located inside the longitudinal guide rail is fixedly installed at the bottom end of the longitudinal movable block, the bottom end of the return spring being connected to the bottom end of the inner cavity of the longitudinal guide rail.

[0017] As a further technical solution of the present invention, an ear plate is fixedly installed at the top of the longitudinal guide rail, and a limiting hole is opened in the middle of the ear plate. The limiting hole is adapted to the output end of the limiting telescopic rod. When the top of the longitudinal movable block contacts the top of the inner cavity of the longitudinal guide rail, the limiting telescopic rod and the limiting hole are movably engaged.

[0018] When the circuit board contacts the clamping plate, both ends of the circuit board can contact the clamping plate and the bottom end can contact the drive wheel, thus completing the three-point support of the circuit board. At this time, the cutting and punching machine can be used to cut the circuit board. When it is necessary to punch the circuit board, the bottom end of the circuit board can be attracted by the vacuum suction cup, and the main cylinder can be activated at the same time to drive the support platform to rise. At this time, the circuit board rises with it, and the limit of the clamping components at both ends is released. At this time, the circuit board is supported by only two vacuum suction cups. At the same time, the support platform rises and contacts the drill bit to complete the drilling operation.

[0019] By utilizing the vertical displacement of the support platform and the limiting process of the clamping components—that is, the support platform moves downward to clamp and upward to release—and with the help of auxiliary support components, the circuit board is transformed from three-sided support to two-point support, making it adaptable to different clamping requirements during cutting and drilling. At the same time, the circuit board can move upward during drilling, avoiding the problems of excessive wear caused by the downward displacement of traditional drill bits and the support of the base plate. It also avoids the problem of traditional fixtures where the drill bit cannot drill at the edge position due to clamping at both ends, significantly improving processing accuracy and quality.

[0020] As a further technical solution of the present invention, drive wheels are movably installed on the top of the support platform near the front and rear sides, and motors are built into the drive wheels. Dust collection hoods are embedded on the front and rear sides near the middle of the support platform. The bottom of the dust collection hood is fixedly connected to a negative pressure pipe, and the negative pressure pipe is connected to an external negative pressure fan.

[0021] During circuit board feeding, the support platform, located at its highest point, connects to the circuit boards on the feeding conveyor belt. Once the circuit boards are processed, the worktable carrying them rotates to the discharge conveyor belt. At this point, the limit telescopic rod can be activated to shorten it, preventing it from engaging with the limit hole. When the restriction is released, the reset spring automatically resets and lowers the longitudinal movable block. The mounting block and vacuum suction cup then descend, releasing their adhesion to the circuit board. After release, the drive wheel can be activated to rotate and transport the circuit board from the support platform to the discharge conveyor belt, completing the automatic discharge process.

[0022] By further utilizing the vertical displacement of the support platform, and in conjunction with the single rotation of the worktable and the function of the auxiliary support components, the circuit board can be automatically fed and clamped and fixed. It can automatically switch between two modes: cutting clamping and drilling clamping. After processing, it can automatically unload the material. The entire process can be completed automatically, effectively avoiding the problem that traditional devices still require manual assistance for feeding and unloading. This significantly reduces labor intensity, lowers safety hazards, and improves overall processing efficiency.

[0023] Meanwhile, during the cutting and drilling of circuit boards, an external negative pressure fan can be turned on to generate negative pressure inside the dust hood and negative pressure pipe to suck out the debris and dust generated during the circuit board processing, thus avoiding any impact on subsequent processing.

[0024] A processing method for an integrated cutting and punching processing equipment for circuit board processing includes the following steps:

[0025] S1: When in use, the three workbenches correspond to the feeding conveyor belt, the discharging conveyor belt, and the cutting and punching integrated machine, respectively. When any workbench corresponds to the cutting and punching integrated machine, the two workbenches correspond to the discharging end of the feeding conveyor belt and the feeding end of the discharging conveyor belt, respectively.

[0026] S2: By turning on the motor, the three worktables can be driven to move circumferentially under the action of the cam divider. When any worktable rotates to the feeding conveyor belt, the feeding conveyor belt can be driven to transport the circuit board to the top of the support platform. At this time, the main cylinder can be turned to drive the support platform to move downward. At this time, the two connecting rods deflect inward and drive the two clamping plates to move closer to each other until they contact the circuit board, thus completing the clamping process of the circuit board.

[0027] S3: At this time, the circuit board is fixed by the support platform at the bottom and the clamping plates on the left and right sides. The worktable carrying the circuit board continues to rotate and rotates to the bottom of the cutting and punching machine. At this time, the cutting and punching machine can be used to cut the circuit board. If drilling is required, the vacuum suction cup can be turned on to suction and fix the bottom of the circuit board. At the same time, the main cylinder is turned on to control the support platform to rise. At this time, the two clamping plates move away from each other and release the fixation of the side of the circuit board. The circuit board is only supported by the two auxiliary support components at the bottom. At this time, drilling can be performed.

[0028] S4: During the cutting and drilling process, the external negative pressure fan can be turned on to generate negative pressure inside the dust hood and negative pressure pipe to remove the processing debris. After the processing is completed, the worktable can be controlled to continue rotating, that is, to rotate the circuit board loaded with the processed circuit board to the discharge conveyor belt. At this time, by controlling the limit telescopic rod to shorten and release the jamming between it and the limit hole, the limit of the longitudinal movable block can be released. At this time, the longitudinal movable block moves downward under the action of the return spring and releases the fixation between it and the circuit board.

[0029] S5: At this point, the circuit board is only in contact with the drive wheel at its bottom end and there are no limiting or fixing measures. The drive wheel can be opened to drive the drive wheel to rotate and export the circuit board to the discharge conveyor belt. The worktable located on the feeding conveyor belt can be fed at the same time, and the worktable located below the cutting and punching machine can be cut and punched at the same time. Repeating the above steps can automatically complete the entire processing process.

[0030] The beneficial effects of this invention are as follows:

[0031] 1. This invention utilizes the vertical displacement of the support platform and the limiting process of the clamping components. Specifically, the downward displacement of the support platform achieves clamping, and the upward displacement of the support platform achieves release. In conjunction with the auxiliary support components, the circuit board is transformed from three-sided support to two-point support, making it adaptable to different clamping requirements during cutting and drilling. At the same time, the circuit board can be moved upward during drilling, avoiding the problems of excessive wear caused by the downward displacement of traditional drill bits and the support of the base plate. It also avoids the problem that traditional clamps cannot drill at the edge positions due to clamping at both ends, significantly improving processing accuracy and quality.

[0032] 2. By further utilizing the vertical displacement of the support platform and coordinating with the single rotation of the worktable and the auxiliary support components, this invention can achieve automatic feeding and clamping of circuit boards, and automatically switch between two modes: cutting clamping and drilling clamping. After processing, it can automatically unload the material. The entire process can be completed automatically, effectively avoiding the problem that traditional devices still require manual assistance for feeding and unloading, significantly reducing labor intensity and safety hazards, and improving overall processing efficiency.

[0033] 3. This invention utilizes the vertical displacement of the support platform. When the support platform is at a high point, it can connect to the circuit board from the feeding conveyor belt and discharge the circuit board. When the support platform is at a low point, it can automatically clamp the circuit board. The whole process is completed quickly. The clamping and loosening of the circuit board can be completed quickly without repeated manual adjustments. This can shorten the fixing time of the circuit board during processing and improve processing efficiency. Attached Figure Description

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] like Figures 1 to 8As shown in the embodiment of the present invention, an integrated cutting and punching processing equipment for circuit board processing includes a base plate 1. Reinforcing ribs 3 are fixedly installed at equal angles on the outer side of the base plate 1. An annular guide rail 2 is provided on the outer side of the base plate 1. The other end of the reinforcing ribs 3 is connected to the inner side of the annular guide rail 2. Three worktables 9 are provided at equal angles above the base plate 1. Guide blocks 10 are fixedly installed on the bottom end of each worktable 9 near its outer side. The worktables 9 are movably engaged with the annular guide rail 2 via the guide blocks 10, allowing the guide blocks 10 to rotate relative to the annular guide rail 2. A support frame 6 is installed on the end of each worktable 9 away from the guide blocks 10. A base 4 is provided at one end of the outer side of the ring guide rail 2. A cutting and punching integrated machine 5 is fixedly installed at the top of the base 4. The cutting and punching integrated machine 5 is located directly above a workbench 9 on one side. A support platform 14 is provided in the middle of the top of the workbench 9. A main cylinder 16 is fixedly installed in the middle of the workbench 9. The output end of the main cylinder 16 is connected to the middle of the bottom of the support platform 14. Mounting brackets 11 are installed on both the left and right sides of the top of the workbench 9. Horizontal guide rails 12 are installed on the front and rear sides of the inner side of the top of the mounting brackets 11. A clamping assembly 13 is provided between the front and rear horizontal guide rails 12. Auxiliary support assemblies 19 are installed on both the front and rear sides of the support platform 14.

[0045] Before actual use, the three worktables 9 should be aligned with the feeding conveyor belt, the discharging conveyor belt, and the cutting and punching machine 5 respectively. Ensure that each worktable 9 can be aligned with the feeding conveyor belt, the discharging conveyor belt, and the cutting and punching machine 5 after being rotated 120 degrees. At the same time, the cutting and punching machine 5 can perform linear cutting and punching operations on the circuit board.

[0046] like Figure 1 and Figure 2 as well as Figure 3 As shown, a motor 7 is fixedly installed at the center of the top of the base plate 1. A cam divider 8 is provided at the top of the motor 7. The input end of the cam divider 8 is connected to the output end of the motor 7. A connecting plate is provided between the three support frames 6. The three support frames 6 are set at equal angles on the outer side of the connecting plate and connected to the outer side of the connecting plate. The output shaft of the cam divider 8 is connected to the bottom end of the connecting plate. The single rotation angle of the cam divider 8 is 120 degrees.

[0047] When in use, power can be input to the cam divider 8 by turning on the motor 7, and the cam divider 8 will drive the top worktable 9 to rotate circumferentially. The angle of the worktable 9 rotating once is exactly 120 degrees, and it corresponds to the feeding conveyor belt, the discharging conveyor belt and the cutting and punching integrated machine 5.

[0048] like Figure 2 and Figure 3 as well as Figure 4 and Figure 8As shown, the clamping assembly 13 includes an extension rod 136, which is connected to the side of the support platform 14. The end of the extension rod 136 away from the support platform 14 is fixedly connected to a second fixing seat 134. The clamping assembly 13 also includes a locking block 131, which is movably engaged with the transverse guide rail 12. The locking block 131 moves left and right relative to the transverse guide rail 12. A connecting frame 132 is installed at the top between every two locking blocks 131. A clamping plate 137 is installed at the end of the connecting frame 132 away from the mounting frame 11. An anti-slip groove is provided on the inner side of the clamping plate 137. A first fixing seat 133 is installed at the bottom of the locking block 131. A connecting rod 135 is movably connected to the end of the first fixing seat 133 away from the locking block 131 through a pivot. The end of the connecting rod 135 away from the first fixing seat 133 is movably connected to the second fixing seat 134 through a pivot.

[0049] When processing circuit boards, the feeding conveyor belt can transport a single circuit board to the top of the worktable 9. At this time, the circuit board is directly above the support platform 14. When the bottom of the circuit board contacts the top of the support platform 14, the main cylinder 16 can be activated to drive the support platform 14 to move downward. When the support platform 14 moves downward, a force can be applied to the connecting rod 135. Multiple connecting rods 135 deflect inward, and the angle between the connecting rod 135 and the extension rod 136 decreases accordingly. At the same time, a pulling force is applied to the clamping block 131, which drives the clamping block 131 to move relative to the transverse guide rail 12. Finally, the two clamping plates 137 on the left and right sides move closer to each other until the clamping plates 137 contact the side of the circuit board, completing the clamping process of the circuit board.

[0050] By utilizing the vertical displacement of the support platform 14, when the support platform 14 is at a high point, it can connect to the circuit board from the feeding conveyor belt and discharge the circuit board at the high point. When the support platform 14 is at a low point, it can automatically clamp the circuit board. The whole process is completed quickly. The clamping and loosening of the circuit board can be completed quickly without repeated manual adjustments, which can shorten the fixing time of the circuit board during the processing and improve the processing efficiency.

[0051] like Figure 3 and Figure 5 as well as Figure 6 and Figure 7As shown, the auxiliary support assembly 19 includes a longitudinal guide rail 191, which is connected to the end face of the support platform 14. A longitudinal movable block 192 is movably engaged inside the longitudinal guide rail 191. The longitudinal movable block 192 moves vertically relative to the longitudinal guide rail 191. Mounting blocks 193 are fixedly installed on the side of the longitudinal movable block 192 away from the support platform 14. Vacuum suction cups 194 are installed on the top of each mounting block 193. A mounting plate 195 is fixedly installed on the side of the longitudinal movable block 192 away from the mounting block 193. The side of the mounting plate 195 closest to the mounting block 193 is fixedly mounted. A limiting telescopic rod 196 is fixedly installed. A return spring 199 located inside the longitudinal guide rail 191 is fixedly installed at the bottom end of the longitudinal movable block 192. The bottom end of the return spring 199 is connected to the bottom end of the inner cavity of the longitudinal guide rail 191. An ear plate 197 is fixedly installed at the top end of the longitudinal guide rail 191. A limiting hole 198 is opened in the middle of the ear plate 197. The limiting hole 198 is adapted to the output end of the limiting telescopic rod 196. When the top end of the longitudinal movable block 192 contacts the top end of the inner cavity of the longitudinal guide rail 191, the limiting telescopic rod 196 and the limiting hole 198 are movably engaged.

[0052] Example 1: When the circuit board is in contact with the clamping plate 137, the left and right ends of the circuit board can contact the clamping plate 137 and the bottom end can contact the drive wheel 15, thus completing the three-point support of the circuit board. At this time, the cutting and punching integrated machine 5 can be used to cut the circuit board. When it is necessary to punch the circuit board, the bottom end of the circuit board can be adsorbed by opening the vacuum suction cup 194, and the main cylinder 16 is opened at the same time to drive the support platform 14 to rise. At this time, the circuit board rises accordingly, and the limit of the clamping components 13 at both ends is released. At this time, the circuit board is supported by only two vacuum suction cups 194, and the support platform 14 rises and contacts the drill bit to complete the drilling operation.

[0053] By utilizing the vertical displacement of the support platform 14 and the limiting process of the clamping component 13, the support platform 14 is moved downward to clamp and upward to release. In conjunction with the auxiliary support component 19, the circuit board is transformed from three-sided support to two-point support, making it adaptable to different clamping requirements during cutting and drilling. At the same time, the circuit board can be moved upward during drilling to avoid the problem of excessive wear caused by the downward displacement of traditional drill bits and the support of the base plate. It also avoids the problem that traditional fixtures cannot drill holes at the edge positions due to clamping at both ends, significantly improving processing accuracy and quality.

[0054] like Figure 5 and Figure 6As shown, drive wheels 15 are movably installed on the top of the support platform 14 near the front and rear sides. The drive wheels 15 have motors built in them. Dust hoods 17 are embedded on the front and rear sides near the middle of the support platform 14. The bottom of the dust hood 17 is fixedly connected to a negative pressure pipe 18, which is connected to an external negative pressure fan.

[0055] Example 2: During the feeding of the circuit board, the support platform 14 is at its highest point and can connect the circuit board on the feeding conveyor belt. After the circuit board is processed, the worktable 9 carrying the processed circuit board rotates to the discharge conveyor belt. At this time, the limit telescopic rod 196 can be activated to control the limit telescopic rod 196 to shorten. At this time, the limit telescopic rod 196 is no longer locked with the limit hole 198. When the restriction is released, the reset spring 199 automatically resets and drives the longitudinal movable block 192 to descend. At this time, the mounting block 193 and the vacuum suction cup 194 descend accordingly to release the adsorption fixation between them and the circuit board. After the fixation is released, the drive wheel 15 can be activated to drive the drive wheel 15 to rotate and convey the circuit board at the top out of the support platform 14 and into the discharge conveyor belt, completing the automatic discharge.

[0056] By further utilizing the vertical displacement of the support platform 14, and in conjunction with the single rotation of the worktable 9 and the function of the auxiliary support component 19, the circuit board can be automatically fed and clamped and fixed. It can automatically switch between two modes: cutting clamping and drilling clamping. After processing, it can automatically unload the material. The entire process can be completed automatically, effectively avoiding the problem that traditional devices still require manual assistance for feeding and unloading. This significantly reduces labor intensity, lowers safety hazards, and improves overall processing efficiency.

[0057] Meanwhile, during the cutting and drilling of the circuit board, the external negative pressure fan can be turned on to generate negative pressure inside the dust hood 17 and the negative pressure pipe 18 to suck out the debris and dust generated during the circuit board processing, thus avoiding any impact on subsequent processing.

[0058] A processing method for an integrated cutting and punching processing equipment for circuit board processing includes the following steps:

[0059] S1: When in use, the three worktables 9 correspond to the feeding conveyor belt, the discharging conveyor belt, and the cutting and punching integrated machine 5, respectively. When any worktable 9 corresponds to the cutting and punching integrated machine 5, the two worktables 9 correspond to the discharging end of the feeding conveyor belt and the feeding end of the discharging conveyor belt, respectively.

[0060] S2: By turning on the motor 7, the three worktables 9 can be driven to move in the circumferential direction under the action of the cam divider 8. When any worktable 9 rotates to the feeding conveyor belt, the feeding conveyor belt can be driven to transport the circuit board to the top of the support platform 14. At this time, the main cylinder 16 can be turned on to drive the support platform 14 to move downward. At this time, the two connecting rods 135 deflect inward and drive the two clamping plates 137 to move closer to each other until they contact the circuit board, thus completing the clamping process of the circuit board.

[0061] S3: At this time, the circuit board is fixed by the support platform 14 at the bottom and the clamping plates 137 on the left and right sides. The worktable 9 carrying the circuit board continues to rotate and rotates to the bottom of the cutting and punching machine 5. At this time, the cutting and punching machine 5 can be used to cut the circuit board. If drilling is required, the vacuum suction cup 194 is turned on to suction and fix the bottom of the circuit board. At the same time, the main cylinder 16 is turned on to control the support platform 14 to rise. At this time, the two clamping plates 137 move away from each other and release the fixation of the side of the circuit board. The circuit board is only supported by the two auxiliary support components 19 at the bottom. At this time, drilling can be performed.

[0062] S4: During the cutting and drilling process, the external negative pressure fan can be turned on to generate negative pressure inside the dust hood 17 and the negative pressure pipe 18 to remove the processing debris. After the processing is completed, the worktable 9 can be controlled to continue rotating, that is, to rotate the circuit board loaded with the processed circuit board to the discharge conveyor belt. At this time, by controlling the limit telescopic rod 196 to shorten and release the jamming between it and the limit hole 198, the limit of the longitudinal movable block 192 can be released. At this time, the longitudinal movable block 192 moves downward under the action of the return spring 199 and releases the fixation between it and the circuit board.

[0063] S5: At this time, the circuit board is only in contact with the bottom end of the drive wheel 15 without any limiting or fixing measures. The drive wheel 15 can be opened to drive the drive wheel 15 to rotate and push the circuit board to the discharge conveyor belt. The worktable 9 located on the feeding conveyor belt can be fed at the same time, and the worktable 9 located below the cutting and punching machine 5 can be cut and punched at the same time. Repeating the above steps can automatically complete the entire processing process.

[0064] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
