Technical Field

[0001] The present application relates to the field of flexible circuit board production equipment, and in particular to an FPC punching machine tool for removing static electricity. Background Art

[0002] FPC is a printed circuit, also known as a flexible circuit board. It is favored for its excellent properties such as light weight, thin thickness, and free bending and folding. Therefore, it is widely used in MP3, DVD, digital cameras, mobile phones, medical, automotive and aerospace fields.

[0003] At present, the FPC used in the new energy power battery BMS management system is usually in the shape of a long strip after production, so it is necessary to punch the long strip FPC into multiple block structures with the required shape. The punching process of FPC will use a punching machine. Before the punching machine punches the FPC, the FPC needs to be treated with static electricity. Therefore, a punching machine that can eliminate static electricity is needed to reduce the impact of static electricity on FPC products. Summary of the invention

[0004] In order to facilitate the elimination of static electricity on FPC, the present application provides an FPC punching machine for eliminating static electricity.

[0005] The present application provides a FPC punching machine for removing static electricity, which adopts the following technical solution:

[0006] A static-free FPC punching machine tool comprises a base and a workbench arranged on the base, wherein the top surface is used for placing the FPC to be punched;

[0007] A punching mechanism, located above the workbench, for punching the FPC on the workbench;

[0008] A feeding mechanism, used to deliver the FPC to the workbench;

[0009] A first exhaust duct is arranged on a side of the workbench close to the feeding mechanism, the first exhaust duct is provided with a first exhaust port facing downward, a negative ion fan is arranged on one side of the workbench, and the air outlet side of the negative ion fan is connected to the first exhaust duct;

[0010] A second air exhaust pipe is slidably disposed on the base, the second air exhaust pipe is provided with a second air exhaust port facing upward, and the second air exhaust pipe is connected to the air outlet side of the negative ion fan;

[0011] The driving mechanism includes an airbag, a connecting block, a first spring, a baffle, a first pushing assembly and a second pushing assembly. The length direction of the airbag is parallel to the table top of the workbench, one end of the airbag is closed and fixedly connected to the base, the other end of the airbag is provided with an opening and fixedly connected to the connecting block, the connecting block is provided with a cavity connected to the inside of the airbag, the connecting block is slidably arranged on the base, the connecting block is fixedly connected to the second exhaust pipe, the first spring is connected between the connecting block and the base so that the connecting block has a tendency to slide toward the side close to the fixed end of the airbag, an air inlet and an exhaust port are provided on the connecting block, the air inlet is connected to the air outlet side of the negative ion fan, the baffle is slidably arranged inside the connecting block, the baffle is used to close one of the air inlet and the exhaust port, the first pushing assembly and the second pushing assembly are respectively arranged on both sides of the workbench, the first pushing assembly is used to drive the baffle to slide toward the side close to the air inlet, and the second pushing assembly is used to drive the baffle to slide toward the side close to the exhaust port.

[0012] By adopting the above technical scheme, the first exhaust duct and the second exhaust duct are arranged so that the negative ion gas generated by the negative ion fan can be evenly covered on the surface of the FPC through the two exhaust vents in different directions. The first exhaust vent is used to remove static electricity from the FPC before punching, and the second exhaust vent is used to remove static electricity from the FPC after punching, thereby effectively eliminating static electricity on the FPC, thereby avoiding damage to the FPC caused by static electricity; the driving mechanism enables the second exhaust duct to slide on the workbench, further improving the uniformity of the distribution of the negative ion gas and ensuring the effect of removing static electricity; the present scheme drives the second exhaust duct to slide through the cooperation of the air bag, the connecting block and the first spring. Compared with the direct driving method through the air cylinder or the oil cylinder, since no additional power source is required, it helps to reduce energy consumption. Furthermore, it can avoid the design of a more complex electronic control system, which helps to improve the reliability of the system.

[0013] Optionally, a material picking mechanism is provided above the workbench, and the material picking mechanism includes a mounting plate, a suction cup and an air pump. The mounting plate is provided on one side of the punching mechanism so that the mounting plate can slide along the punching direction along with the punching mechanism. The suction cup and the air pump are both provided on the mounting plate, and the open side of the suction cup is used to abut against the FPC on the workbench, and the air pump is connected to the suction cup.

[0014] By adopting the above technical solution, the mounting plate slides along with the punching mechanism to ensure that the suction cup is accurately aligned with the FPC that has been punched. The air pump controls the suction cup to absorb or release the FPC to achieve automatic material removal, which helps to improve the overall efficiency and safety of the production line.

[0015] Optionally, the first pushing assembly includes a first connecting rod, a first magnet block and a second magnet block, the first connecting rod is fixedly connected to the baffle, the first connecting rod is slidably penetrated into the connecting block, the first magnet block is fixedly connected to one end of the first connecting rod located outside the connecting block, the second magnet block is fixedly connected to the base, and the second magnet block is used to engage with the first magnet block.

[0016] By adopting the above technical solution, when the airbag is inflated, the airbag stretches, causing the connecting block to slide. When the connecting block slides to the side close to the second magnet block, the first magnet block can slide outward due to the attraction of magnetic force until the first magnet block and the second magnet block are attracted. Therefore, when the first magnet block slides outward, the baffle can be driven to slide through the first connecting rod, so that the baffle closes the air inlet and opens the exhaust port. Since air cannot enter the airbag at this time, the first spring can make the connecting block slide in the opposite direction, the airbag is compressed, and the gas in the airbag is discharged through the exhaust port, completing the resetting of the connecting block; therefore, the first pushing assembly can realize the switching of the airbag from the inflated state to the exhausted state.

[0017] Optionally, the second pushing assembly includes a second connecting rod, a support rod, a push plate and an avoidance component, the second connecting rod is fixedly connected to the baffle, the second connecting rod is slidably penetrated into the connecting block, the support rod is vertically fixedly connected to one end of the second connecting rod located outside the connecting block, the push plate is fixedly connected to the mounting plate, the top wall of the push plate is used to resist against the support rod so that when the push plate moves up, the support rod can be pushed to move toward the side close to the exhaust port, and the avoidance component is arranged on the push plate so that the push plate can pass through the support rod when it moves down.

[0018] By adopting the above technical solution, when the push plate slides upward, it can push the support rod to slide horizontally, so that the support rod drives the baffle to slide through the second connecting rod until the baffle closes the exhaust port and the air inlet opens. At this time, the negative ion fan can blow air into the airbag through the air inlet, thereby making the airbag bulge and stretch, so that the second pushing component can realize the switching of the airbag from a compressed state to an inflated state.

[0019] Optionally, the avoidance component includes a rotating plate and a torsion spring. An avoidance groove is opened on the push plate. The rotating plate is located in the avoidance groove. Two rotating plates are provided and are rotatably connected to the inner wall of the avoidance groove. The torsion spring is fixedly connected between the rotating plate and the inner wall of the avoidance groove. The torsion spring presses the two rotating plates against each other.

[0020] When the two levers are in the forward position, the two levers are in a forward position, the two levers being moved in a reverse direction and being able to move relative to each other as the levers move upward.

[0021] Optionally, a third magnet block is fixedly connected to the baffle, and a fourth magnet block for engaging with the third magnet block is fixedly connected to the inner wall of the cavity in the connecting block. When the third magnet block and the fourth magnet block are attracted to each other, the baffle closes the air inlet.

[0022] By adopting the above technical solution, when the third magnet block and the fourth magnet block are attracted to each other, the position of the baffle can be fixed. Therefore, during the deflation of the airbag, when the first spring pushes the connecting block to slide back to the initial position, the baffle inside the connecting block is not easy to slide relative to the connecting block under the action of inertia, thereby ensuring the sealing effect of the baffle on the air inlet.

[0023] Optionally, a third downward air outlet is provided on the second air outlet duct.

[0024] By adopting the above technical solution, the third air outlet can blow air downward, which can remove static electricity on the surface of the workbench on the one hand, and clean the surface of the workbench and blow away the dust on the surface of the workbench, thereby ensuring the processing effect.

[0025] Optionally, a cleaning plate is fixedly connected to the connecting block, and the cleaning plate is used to abut against the top wall of the workbench. A collection box is provided on one side of the workbench away from the fixed end of the airbag.

[0026] By adopting the above technical solution, after the FPC punching is completed, the cut waste is accumulated on the top surface of the workbench. The cleaning plate can maintain contact with the top wall of the workbench during the sliding process of the connecting block, and push the waste on the top surface of the workbench into the collection box, ensuring the cleanliness of the workbench surface, thereby improving the punching accuracy and product quality of the FPC.

[0027] Optionally, a positioning frame is provided on the top wall of the workbench.

[0028] By adopting the above technical solution, the positioning frame can effectively limit the position of the FPC, ensure that the FPC remains stable during the punching process, avoid the decrease in punching accuracy due to position deviation, and improve the product yield.

[0029] Optionally, a receiving groove is provided on the top wall of the workbench, and the bottom end of the positioning frame is vertically slidably arranged in the receiving groove. A second spring is connected between the positioning frame and the inner wall of the receiving groove, and the second spring causes the positioning frame to have a tendency to slide toward a side away from the receiving groove. A support block is fixedly connected to the positioning frame, and a slope is provided on the support block. A push block is fixedly connected to the connecting block, so that when the connecting block drives the push block to slide horizontally, the push block can push the support block downward, so that the positioning frame slides into the receiving groove.

[0030] By adopting the above technical solution, the positioning frame can automatically pop out when not affected by external force, ensuring the accurate position of the FPC during the processing, improving production efficiency and product quality; the cooperation of the push block and the support block allows the connecting block to drive the positioning frame to slide downward into the receiving groove when sliding horizontally, so that the positioning frame avoids the sliding process of the cleaning plate, which helps to ensure the cleaning effect of the cleaning plate on the waste on the workbench.

[0031] In summary, this application includes the following beneficial technical effects:

[0032] 1. The negative ion fan blows ion air to the FPC through the first and second exhaust ducts, which can effectively neutralize the static electricity on the surface of the FPC, thereby improving the quality and safety of FPC punching.

[0033] 2. The driving mechanism utilizes the cooperation of the airbag, the connecting block and the first spring to realize the automatic sliding of the second exhaust duct, ensuring that the negative ion wind can evenly cover the FPC, further enhancing the static electricity removal effect.

[0034] 3. When the connecting block slides, the cleaning plate can be driven to slide, thereby pushing the waste on the workbench into the collection box, which can realize the rapid cleaning of the waste and help improve work efficiency.

[0035] 4. The positioning frame can position the FPC that slides onto the workbench. When the connecting block slides horizontally, the positioning frame can be pushed down into the receiving groove for avoidance, so that when the connecting block slides, it can drive the cleaning plate to slide smoothly, which helps to ensure the cleaning effect of the cleaning plate.

DETAILED DESCRIPTION

[0048] The following combination Figure 1-Figure 11 This application is described in further detail.

[0049] The present application discloses a FPC punching machine for removing static electricity. Figure 1 , Figure 2 and Figure 3 The FPC punching machine for removing static electricity includes a base 1, a workbench 2 and a punching mechanism 3. The workbench 2 is fixedly connected to the base 1, and the top surface of the workbench 2 is horizontally arranged. The punching mechanism 3 is arranged above the workbench 2, and the punching mechanism 3 includes a mounting seat 31, a punching block 32 and a punching die. The mounting seat 31 is horizontally slidably arranged on the base 1, and a horizontal oil cylinder for driving the mounting seat 31 to slide is arranged on the base 1. The punching block 32 is vertically slidably arranged on the mounting seat 31, and a vertical oil cylinder for driving the punching block 32 to slide is arranged on the mounting seat 31; in other embodiments, the mounting seat 31 and the punching block 32 can also be driven to slide by the cooperation of a motor and a screw. The punching die is fixedly connected to the bottom wall of the punching block 32, so that when the punching block 32 moves downward, it can drive the punching die to move downward, thereby punching the FPC placed on the top surface of the workbench 2, and cutting out an FPC block with a desired shape.

[0050] The punching block 32 is also provided with a material taking mechanism 9, which includes a mounting plate 91, a suction cup 92 and an air pump. The mounting plate 91 is fixedly connected to the punching block 32; since the mounting plate 91 is located on one side of the punching block 32, the mounting plate 91 will not interfere with the surface of the workbench 2 during the downward movement of the punching block 32, so that the punching process can proceed smoothly. The suction cup 92 is fixedly connected to the bottom wall of the mounting plate 91, and the opening side of the suction cup 92 faces downward; the air pump is fixedly connected to the mounting plate 91, and the air pump is connected to the opening side of the suction cup 92. Therefore, after the air pump is started, the opening side of the suction cup 92 can be vacuumed, so as to suck up the FPC after punching placed on the top surface of the workbench 2. Among them, there are multiple suction cups 92, and the suction cups 92 can be set as needed, so that the suction cups 92 only suck up the finished FPC after punching, and the cut waste is still placed on the top surface of the workbench 2, which is convenient for the subsequent unified cleaning of the waste on the workbench 2.

[0051] A feeding mechanism 4 is provided on one side of the workbench 2, and the feeding mechanism 4 includes a conveyor belt, and the top surface of the conveyor belt is flush with the top surface of the workbench 2, so that the conveyor belt can convey the FPC to be punched to the top surface of the workbench 2, thereby realizing automatic feeding of the FPC and improving work efficiency.

[0052] A first exhaust duct 5 is provided at one end of the workbench 2 close to the feeding mechanism 4, and the first exhaust duct 5 is located above the feeding mechanism 4. The first exhaust duct 5 is arranged along the width direction of the workbench 2; a plurality of first exhaust ducts 5 are provided and are evenly spaced and arranged along the length direction of the workbench 2, and the plurality of first exhaust ducts 5 are interconnected. A first exhaust port 51 is provided at the bottom of the first exhaust duct 5, and a plurality of first exhaust ports 51 are provided and are evenly spaced and arranged along the length direction of the first exhaust duct 5. A negative ion fan 6 is fixedly connected to the base 1, and the air outlet side of the negative ion fan 6 is connected to the first exhaust duct 5. Therefore, after the negative ion fan 6 is started, the first exhaust port 51 on the first exhaust duct 5 can blow out ion wind downward, thereby neutralizing the charge on the FPC on the conveying mechanism, so as to achieve the purpose of removing static electricity.

[0053] Reference Figure 4 , the workbench 2 is also provided with a second exhaust duct 7, which is arranged along the length direction of the workbench 2. The second exhaust duct 7 is provided with a second exhaust port 71 facing upward, and a plurality of the second exhaust ports 71 are arranged and evenly spaced along the length direction of the second exhaust duct 7. The second exhaust duct 7 is connected to the air outlet side of the negative ion blower 6, so the second exhaust port 71 on the second exhaust duct 7 can blow out ion wind upward, thereby removing static electricity from the punched FPC adsorbed on the suction cup 92 again, thereby reducing the impact of static electricity on the FPC. Further, the second exhaust duct 7 is also provided with a third exhaust port 72 facing downward, and a plurality of the third exhaust ports 72 are arranged and evenly spaced along the length direction of the third exhaust duct, so that the third exhaust port 72 can be used to blow air downward to remove static electricity and clean the surface of the workbench 2.

[0054] Reference Figure 5 , Figure 6 and Figure 7, the second exhaust duct 7 is slidably arranged on the base 1 along the width direction of the workbench 2, and a driving mechanism 8 for driving the second exhaust duct 7 to slide is arranged on the base 1. Two groups of driving mechanisms 8 are arranged, and they are respectively located at the two ends of the second exhaust duct 7. The driving mechanism 8 includes an airbag 81, a connecting block 82, a first spring 83, a baffle 84, a first pushing component 85 and a second pushing component 86. The airbag 81 is arranged in a long strip shape, and the length direction of the airbag 81 is arranged along the width direction of the workbench 2. One end of the airbag 81 is closed, and the end of the airbag 81 is fixedly connected to the base 1; the other end of the airbag 81 is open, and the connecting block 82 is located at the end of the airbag 81. The connecting block 82 is slidably arranged on the base 1 along the width direction of the workbench 2, and a slider is fixedly connected to the bottom of the connecting block 82. A slide groove is arranged on the base 1 on one side of the workbench 2, and the slider is slidably arranged in the slide groove. The connecting block 82 is fixedly connected to the airbag 81, and a cavity is provided inside the connecting block 82, which is connected to the opening of the airbag 81, so that the cavity inside the connecting block 82 is connected to the inside of the airbag 81. The connecting block 82 is provided with an air inlet 821 and an exhaust port 822 connected to the internal cavity, and the air inlet 821 is located on a side of the exhaust port 822 away from the fixed end of the airbag 81. The air inlet 821 is connected to the air outlet side of the negative ion blower 6.

[0055] Therefore, the negative ion blower 6 can blow air into the internal cavity of the connecting block 82 through the air inlet 821, and the wind in the internal cavity of the connecting block 82 can flow into the airbag 81, so that the gas in the airbag 81 gradually increases, the airbag 81 gradually stretches, and one end of the airbag 81 that is movably arranged slides outward, so that the connecting block 82 slides to the side away from the fixed end of the airbag 81. The outer wall of the connecting block 82 is fixedly connected to the end of the second exhaust pipe 7, so that when the connecting block 82 slides, the second exhaust pipe 7 can be driven to slide. The first spring 83 is fixedly connected between the connecting block 82 and the base 1. When the airbag 81 is not stretched, the first spring 83 is at its original length. The first spring 83 mainly plays the role of resetting the connecting block 82.

[0056] The baffle 84 is located in the cavity inside the connection block 82, and the baffle 84 is slidably disposed in the cavity inside the connection block 82. When the baffle 84 closes the air inlet 821, the exhaust port 822 is opened; when the baffle 84 closes the exhaust port 822, the air inlet 821 is opened. Therefore, by driving the baffle 84 to slide, the opening and closing states of the air inlet 821 and the exhaust port 822 can be adjusted, thereby realizing the switching of the inflation process and the exhaust process of the airbag 81.

[0057] Reference Figure 5 and Figure 6, the first pushing assembly 85 includes a first connecting rod 851, a first magnet block 852 and a second magnet block 853. The first connecting rod 851 is fixedly connected to the side of the baffle 84 away from the fixed end of the airbag 81, and the first connecting rod 851 is arranged along the width direction of the workbench 2. The end of the first connecting rod 851 passes through the side wall of the connecting block 82, and the first magnet block 852 is fixedly connected to the end of the first connecting rod 851 located outside the connecting block 82. The second magnet block 853 is fixedly connected to the side of the base 1 away from the fixed end of the airbag 81, and the magnetic poles of the second magnet block 853 and the first magnet block 852 on the side close to each other are in opposite directions. Therefore, when the airbag 81 is inflated, the connecting block 82 can slide, and the connecting block 82 drives the first magnet block 852 to slide. When the first magnet block 852 slides to the side close to the second magnet block 853, the first magnet block 852 and the second magnet block 853 can be attracted to each other. Therefore, in the process of the two magnet blocks attracting each other, the first connecting rod 851 can slide relative to the connecting block 82 to the side away from the fixed end of the airbag 81, and the first connecting rod 851 drives the baffle 84 to slide, so that the baffle 84 slides to a state where the air inlet 821 is closed, and the exhaust port 822 is opened at this time; therefore, under the action of the first spring 83, the connecting block 82 can slide to the side close to the fixed end of the airbag 81, so that the airbag 81 is shortened, and the gas in the airbag 81 is discharged from the exhaust port 822.

[0058] Reference Figure 7 In order to improve the stability of the baffle 84 during the sliding process of the connecting block 82, a third magnet block 841 is fixedly connected to the baffle 84, and a fourth magnet block 823 is fixedly connected to the inner wall of the cavity in the connecting block 82. The magnetic poles of the third magnet block 841 and the fourth magnet block 823 on the side close to each other are in opposite directions. When the baffle 84 closes the air inlet 821, the third magnet block 841 and the fourth magnet block 823 are attracted to each other.

[0059] Reference Figure 5 , Figure 7 , Figure 8 and Fig. 9The second pushing assembly 86 includes a second connecting rod 861, a support rod 862, a push plate 863 and an avoidance component. The second connecting rod 861 is fixedly connected to the end of the baffle 84 away from the first connecting rod 851, and the end of the second connecting rod 861 passes through the side wall of the connecting block 82. The support rod 862 is vertically fixedly connected to the end of the second connecting rod 861 outside the connecting block 82, and the support rod 862 is arranged along the length direction of the workbench 2. The push plate 863 is fixedly connected to the mounting plate 91, and the push plate 863 is inclined. The avoidance component includes a rotating plate 864 and a torsion spring. An avoidance groove 8631 is provided on the push plate 863, and the rotating plate 864 is located in the avoidance groove 8631. Two rotating plates 864 are provided, and both are rotatably connected to the inner wall of the avoidance groove 8631. The rotation axes of the two rotating plates 864 are parallel, and the rotation axes of the two rotating plates 864 are located on the side where the two rotating plates 864 are away from each other. Two torsion springs are provided, corresponding to the two rotating plates 864 respectively, and the torsion springs are fixedly connected between the rotating plates 864 and the inner wall of the avoidance groove 8631. Therefore, the torsion springs can make the sides of the two rotating plates 864 close to each other press against each other, thereby closing the avoidance groove 8631. A protrusion is fixedly connected to the inner wall of the avoidance groove 8631. When the two rotating plates 864 press against each other, the protrusion presses against the bottom wall of the rotating plate 864, so that the protrusion can limit the downward rotation of the rotating plate 864. The two rotating plates 864 can only rotate upward, but cannot rotate downward, so that the support rod 862 can be avoided.

[0060] After the FPC is punched, the mounting plate 91 moves downward to drive the suction cup 92 and the push plate 863 to move downward. During the downward movement of the push plate 863, the avoidance groove 8631 on the push plate 863 and the support rod 862 are located in the same vertical direction; therefore, as the push plate 863 moves downward, the bottom of the rotating plate 864 can be abutted against the top of the support rod 862, and then as the push plate 863 moves downward, the two rotating plates 864 rotate upward to avoid, so that the support rod 862 passes through the avoidance groove 8631, so that the downward movement of the push plate 863 will not affect the support rod 862. When the bottom of the suction cup 92 contacts the FPC on the top surface of the workbench 2 after the punching is completed, the air pump draws air so that the inside of the suction cup 92 is in a vacuum state, and the FPC is sucked up; then the mounting plate 91 moves upward to achieve the material removal of the FPC. During the upward movement of the mounting plate 91, the push plate 863 can be driven upward, and the push plate 863 can drive the rotating plate 864 upward. The top of the rotating plate 864 will be against the bottom of the support rod 862. Since the rotating plate 864 cannot rotate downward, as the push plate 863 moves upward, the support rod 862 can slide toward the side close to the fixed end of the airbag 81. The support rod 862 drives the baffle plate 84 to slide through the second connecting rod 861, so that the baffle plate 84 closes the exhaust port 822. At this time, the air inlet 821 is opened, and the bottom end of the push plate 863 is out of contact with the support rod 862. The push plate 863 can continue to move upward with the mounting plate 91.

[0061] Reference Fig.10 A cleaning plate 10 is fixedly connected between the two connecting blocks 82, and the cleaning plate 10 is arranged along the length direction of the workbench 2. The bottom end of the cleaning plate 10 can be against the top surface of the workbench 2, so that when the airbag 81 is extended, the connecting block 82 can slide, and the connecting block 82 drives the cleaning plate 10 to slide, and the cleaning plate 10 can push the waste on the top surface of the workbench 2 to one side, thereby realizing the cleaning of the waste. A collection box 11 is also fixedly connected to one side of the base 1 away from the fixed end of the airbag 81, and the opening of the collection box 11 faces upward, so that the cleaning plate 10 can push the waste on the workbench 2 into the collection box 11, which is convenient for collecting the waste and then emptying it later.

[0062] Reference Fig.10 and Fig.11 Since a feeding mechanism 4 is provided on one side of the workbench 2, in order to keep the position of the FPC sliding onto the workbench 2 consistent and thus ensure the punching effect, a positioning frame 12 is also provided on the top surface of the workbench 2 away from the feeding mechanism 4. Therefore, after the FPC slides onto the workbench 2, one end of the FPC abuts against the positioning frame 12, and the positioning frame 12 can play a role in positioning the FPC.

[0063] Furthermore, a receiving groove 21 is provided on the top wall of the workbench 2, and the shape of the receiving groove 21 is adapted to the positioning frame 12, and the bottom end of the positioning frame 12 is slidably arranged in the receiving groove 21 along the vertical direction. A second spring 13 is connected between the bottom end of the positioning frame 12 and the bottom wall of the receiving groove 21, and under normal conditions, the top end of the positioning frame 12 is located outside the receiving groove 21. A connecting rod 121 is fixedly connected to the positioning frame 12, and a supporting block 122 is fixedly connected to one end of the connecting rod 121 away from the positioning frame 12. The supporting block 122 is arranged in a long strip shape, and an inclined surface is arranged at one end of the supporting block 122; a push block 824 is fixedly connected to the connecting block 82 close to one side of the positioning frame 12, and a rounded corner is arranged on the side of the push block 824 close to the supporting block 122. Therefore, when the connecting block 82 slides horizontally toward the side close to the collecting box 11, the push block 824 can be driven to slide, and the rounded corners on the push block 824 fit with the inclined surface on the support block 122. Then, under the action of the inclined surface, when the push block 824 slides horizontally, the support block 122 can slide vertically downward. The support block 122 drives the positioning frame 12 to slide downward into the accommodating groove 21 through the connecting rod 121 for avoidance, so that the cleaning plate 10 can slide smoothly on the workbench 2 and ensure the cleaning effect of the cleaning plate 10 on the waste on the workbench 2.

[0064] The implementation principle of the FPC punching machine for removing static electricity in the embodiment of the present application is as follows: the negative ion fan 6 is started, and the ion wind is blown downward through the first exhaust port 51 on the first exhaust pipe 5 to remove static electricity from the FPC placed on the feeding mechanism 4; then the feeding mechanism 4 transports the FPC to be punched horizontally to the top surface of the workbench 2 until one end of the FPC abuts against the positioning frame 12 on the workbench 2, and the loading of the FPC is completed. Then the mounting seat 31 is horizontally moved to the top of the workbench 2, and the punching block 32 drives the punching die to move downward to punch the FPC on the workbench 2, cut off the scraps on the FPC, and punch the FPC into the desired shape. After the punching is completed, the punching block 32 drives the punching die to move upward, and the mounting seat 31 slides horizontally to the initial position again. At this time, the mounting plate 91 is located directly above the workbench 2, and then the unloading process of the FPC after the punching is completed can be carried out.

[0065] When unloading, the punching block 32 moves downward, driving the mounting plate 91 downward, so that the suction cup 92 on the mounting plate 91 moves downward until the suction cup 92 contacts the FPC after punching on the workbench 2. At this time, the air pump draws a vacuum on the opening side of the suction cup 92, so that the suction cup 92 sucks up the FPC, and then the mounting plate 91 drives the suction cup 92 to move upward, so that the FPC is separated from the workbench 2.

[0066] In the initial state, the baffle 84 closes the air inlet 821 on the connecting block 82, the air outlet 822 is opened, the airbag 81 is in a compressed state, and the connecting block 82 is located at a side away from the collecting box 11. The push plate 863 can be moved downward during the downward movement of the mounting plate 91, and the bottom of the rotating plate 864 on the push plate 863 will abut against the support rod 862; then, as the push plate 863 moves downward, the two rotating plates 864 can rotate upward to avoid, so that the support rod 862 passes through the avoidance groove 8631; then, the two rotating plates 864 are pressed against each other under the action of the torsion spring, so that the downward movement of the push plate 863 will not affect the support rod 862, and the support rod 862 remains stationary. When the mounting plate 91 moves upward, the push plate 863 is driven upward, and the top of the rotating plate 864 on the push plate 863 abuts against the bottom of the support rod 862. Since the rotating plate 864 cannot rotate downward, as the push plate 863 moves upward, the push plate 863 can push the support rod 862 to slide to the side away from the collection box 11. The support rod 862 drives the baffle plate 84 to slide through the second connecting rod 861 until the baffle plate 84 closes the exhaust port 822, and the air inlet 821 is opened. Then the push plate 863 is separated from the support rod 862, and the push plate 863 continues to move upward under the drive of the mounting plate 91, and stops after moving to a certain height.

[0067] Since the exhaust port 822 is closed and the air inlet 821 is open, the negative ion blower 6 can blow air into the cavity inside the connecting block 82 and the air bag 81 through the air inlet 821, and the gas in the air bag 81 gradually increases, and the movable end of the air bag 81 is extended, so that the connecting block 82 can overcome the elastic force of the first spring 83 and slide to the side close to the collecting box 11. When the connecting block 82 slides, it drives the push block 824 to slide, and the push block 824 abuts against the inclined surface on the support block 122, so that the positioning frame 12 can move down to the receiving groove 21 for avoidance. When the connecting block 82 slides, it can drive the second exhaust pipe 7 and the cleaning plate 10 to slide, and the second exhaust port 71 on the second exhaust pipe 7 can blow ion wind upwards to remove static electricity from the FPC adsorbed on the suction cup 92 again; the third exhaust port 72 on the second exhaust pipe 7 can blow ion wind downwards, which can remove static electricity from the workbench 2 on the one hand and clean the surface of the workbench 2 on the other hand. When the cleaning plate 10 slides, the waste materials accumulated on the top surface of the workbench 2 can be pushed toward the side close to the collecting box 11 until the waste materials are pushed into the collecting box 11, thereby completing the cleaning and collection of the waste materials.

[0068] When the connecting block 82 slides to one end close to the collection box 11, the first magnet block 852 can slide outward under the suction of the second magnet block 853 until the first magnet block 852 and the second magnet block 853 are attracted together, so that the first magnet block 852 can drive the first connecting rod 851 to slide when sliding, and the first connecting rod 851 drives the baffle 84 to slide, so that the baffle 84 closes the air inlet 821 and opens the exhaust port 822. At this time, air cannot enter the airbag 81, and the gas in the airbag 81 can be discharged from the exhaust port 822 under the action of the first spring 83, so that the airbag 81 is shortened rapidly, so that the connecting block 82 slides to the side away from the collection box 11 to reset, until the connecting block 82 slides to the initial position; at this time, the push block 824 is separated from the contact with the support block 122, so that the positioning frame 12 moves up and resets under the action of the second spring 13.

[0069] That is, when the suction cup 92 sucks up the FPC after punching, the connecting block 82 can slide back and forth once, so that the second exhaust duct 7 removes static electricity from the FPC again, and the waste accumulated on the workbench 2 is pushed into the collection box 11 through the cleaning plate 10. Then, the FPC on the suction cup 92 is removed, and the above process is repeated to carry out the punching process of the next FPC.

[0070] The above are optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
