Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of circuit board production, and particularly relates to a copper foil removing device for a press-bonded plate. BACKGROUND

[0002] With the rapid development of 5G communication, cloud computing and data centers, as a core optoelectronic device, optical modules put forward higher requirements on the manufacturing efficiency and precision of the carrier, i.e. optical module PCB board. Such PCB boards generally adopt a multi-layer high-speed material press-bonded structure, and the press-bonding process needs to press-bond outer copper foils on the upper and lower surfaces of the inner layer core plate after the line etching is completed, and fill the semi-cured sheet between the layers to realize the interlayer bonding and insulation. In the existing production process, the press-bonded plate formed after press-bonding will form protruding copper foil burrs on both sides of the plate due to process requirements. The formation of this structure is because the cutting size of the copper foil needs to be larger than the design plate edge to offset the resin flow deviation and interlayer alignment error in the hot pressing process and to ensure the compactness of the interlayer filling.

[0003] However, the removal of the copper foil burrs has long relied on manual operation mode, and the copper foil on both sides of the press-bonded plate is manually torn off by the operator. The efficiency of manual copper foil tearing is not high, especially in mass production, which consumes a lot of manpower, and the force of manual tearing each time is uneven, which easily leads to substrate separation or copper foil residue, affecting the subsequent edge trimming process. At the same time, the processes of press-bonding, edge trimming, drilling and etching have been automated, but the copper foil burr removal link is still in the labor-intensive stage, and manual intervention interrupts continuous production, which restricts the upgrading of intelligent manufacturing. Therefore, it is necessary to develop a copper foil burr removing device with high automation and high reliability to improve the production efficiency of PCB boards. SUMMARY

[0004] In order to solve the above problems of the prior art, the application provides a press-bonded plate copper foil removing device which can automatically and reliably remove the copper foil burrs of the press-bonded plate and improve the production efficiency of the PCB.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the embodiments of the present application are described in detail below in combination with the drawings, but the embodiments described in the present application are part of the embodiments of the present application, not all the embodiments.

[0027] Embodiment 1

[0028] The embodiments of the present application provide a copper foil removing device for pressing plate, as shown in Figure 1 for removing the copper foil burrs 81 on both sides of the pressing plate 8 as shown in Figure 1 . Specifically, the pressing plate 8 is a rectangle with copper foil burrs 81 protruding from the upper and lower surfaces of both sides.

[0029] Specifically, as shown in Figures 1-7As shown, the copper foil removal device in this embodiment includes: a pair of parallel and horizontally arranged mounting rods 1, a rotating mechanism 2, a clamping mechanism 3, a clamping and conveying mechanism 4, a waste discharge mechanism 5, and a mounting block 6.

[0030] Among them, such as Figure 1 and Figure 2 As shown, two mounting blocks 6 are respectively mounted on both sides of a horizontal substrate 9, and are synchronously moved closer to each other or separated from each other along the width direction of the substrate 9.

[0031] like Figures 1-5 As shown, a pair of parallel mounting rods 1 are horizontally mounted on the substrate 9 and located in the middle of the two mounting blocks 6. The two mounting rods 1 are arranged towards the length of the substrate 9, and the plane formed by the axes of the two mounting rods 1 is parallel to the top surface of the substrate 9. The distance between the two mounting rods 1 is greater than the width of the pressing plate 8, where the width of the pressing plate 8 includes the width of the copper foil burr 81. Each mounting rod 1 has two slidingly fitted mating blocks 11, which are paired with the two sides of the corresponding mounting block 6. A connecting rod 61 is provided between the mating block 11 and the paired mounting block 6. The two ends of the connecting rod 61 are rotatably connected to the corresponding mating block 11 and the mounting block 6, respectively. The rotation axes corresponding to the two ends of the connecting rod 61 are both vertically set. When the two mounting blocks 6 move closer to each other synchronously, the two mating blocks 11 separate towards each other under the action of the connecting rod 61. When the two mounting blocks 6 separate towards each other synchronously, the two mating blocks 11 move closer to each other under the action of the connecting rod 61.

[0032] like Figures 3-7 As shown, the four sets of rotating mechanisms 2 include a horizontally rotating shaft 21 rotatably mounted on each mating block 11 and a rotating cylinder 22 coaxially connected to the rotating shaft 21. The rotating shaft 21 is arranged perpendicular to the mounting rod 1, and its end is connected to the bottom of the rotating cylinder 22. The openings of the rotating cylinders 22 corresponding to the two mating blocks 11 on one mounting rod 1 face the other mounting rod 1. Each rotating shaft 21 is coaxially provided with a gear 23 located between the mating block 11 and the rotating cylinder 22. Each rotating shaft 21 is supported below a rack 24 arranged along the length of the mounting rod 1 and meshing with the corresponding gear 23.

[0033] like Figures 3-6 As shown, the clamping mechanism 3 is respectively installed in each rotating cylinder 22. It includes a pair of clamping rods 31 arranged parallel to the rotating shaft 21 and rotating synchronously with the corresponding rotating cylinder 22. The axis of the rotating shaft 21 is always located in the middle of the axis of the two clamping rods 31. One end of the clamping rod 31 extends out of the end face of the rotating cylinder 22 by a predetermined length and is used to clamp and wind the copper foil flash 81 with the rotating cylinder 22. When the two rotating cylinders 22 corresponding to the mounting rod 1 abut, each pair of clamping rods 31 is in an open state and arranged vertically.

[0034] like Figure 1As shown, the clamping mechanism 4 is arranged above the base plate 9 and between the two mounting rods 1, used for horizontally clamping the press plate 8 and transversely feeding it into the two pairs of clamping rods 31 when the two rotating cylinders 22 abut on the mounting rods 1, where the transverse direction refers to the length direction of the press plate 8 consistent with the length direction of the mounting rods 1 when the clamping mechanism 4 feeds the press plate 8. Specifically, in the embodiment, the clamping mechanism 4 adopts the form of a moving platform cooperating with an array of suction cups to suck the press plate 8; in order to ensure that the copper foil flash 81 on both sides of the press plate 8 can enter the corresponding clamping rods 31 when the clamping mechanism 4 feeds the press plate 8 into the two mounting rods 1, a sensor can be installed on the feeding path to detect the position of the edges of the press plate 8 in real time, the suction cups are designed with independently adjustable vacuum partitions, the suction force distribution is dynamically adjusted according to the sensor data to correct the posture of the press plate, and a tapered guide structure can be further arranged on the path to automatically slide the edge copper foil flash 81 into the clamping rods 31; in addition to the form of the moving platform cooperating with the suction cups, the clamping mechanism 4 can also adopt the form of a mechanical hand gripper for feeding, which uses parallel pneumatic clamps to grab the copper foil-free areas at both ends of the press plate 8 for feeding.

[0035] As shown in Figure 3 , Figure 5 , Figure 6 , Figure 10 As shown, the waste removal mechanism 5 includes four pairs of push rods 51 arranged movably along the rotating shaft 21, and each end of each mounting rod 1 is provided with a pair of push rods 51, each pair of push rods 51 is parallel to the mounting rod 1 and arranged vertically and spaced apart; when the push rod 51 moves to a predetermined distance away from the corresponding mounting rod 1, the projection of the clamping rod 31 along the length direction of the mounting rod 1 is located between each pair of push rods 51, and the upper push rod 51 in each pair of push rods 51 is located between the cylinder opening end face of the rotating cylinder 22 and the coiled copper foil flash 81.

[0036] The working principle of the copper foil removal device will be described below in combination with the above structure:

[0037] Feeding stage:

[0038] As shown in Figures 1-6 , the two mounting blocks 6 are synchronously separated, the two connecting rods 61 are pulled to make the two cooperating blocks 11 relatively close to each other, the gear 23 on the rotating shaft 21 engages with the corresponding rack 24, and the two rotating cylinders 22 rotate inward while relatively closing to each other, where the inward rotation refers to that the upper parts of the two rotating cylinders 22 are in a retracted state from the cylinder opening end face of the rotating cylinder 22, until the two rotating cylinders 22 abut on each other; at this time, the mounting block 6 stops, and the two clamping rods 31 in each rotating cylinder 22 are in an open state and arranged vertically.

[0039] As shown in Figure 1 , Figure 5 , Figure 6As shown, the suction cup in the clamping mechanism 4 holds the pressing plate 8 and feeds the pressing plate 8 horizontally and along the length of the substrate 9 between the two mounting rods 1. At the same time, the copper foil flash 81 on both sides of the pressing plate 8 enters between the corresponding two clamping rods 31 until the two abutting rotating cylinders 22 are located at the exact center of the corresponding copper foil flash 81. At this time, the feeding stage of the pressing plate 8 is completed.

[0040] Removal stage: such as Figures 1-6 As shown, each pair of clamping rods 31 returns to the clamping state, clamping the copper foil flash 81. The two mounting blocks 6 synchronously move closer to each other. By pushing the corresponding two connecting rods 61, the two mating blocks 11 synchronously separate towards each other. The gear 23 on the rotating shaft 21 meshes with the corresponding rack 24, causing the two rotating cylinders 22 to rotate outwards while separating towards each other. Here, outward rotation means that, viewed from the end face of the cylinder opening of the rotating cylinder 22, the upper part of the two rotating cylinders 22 is in an outward-spreading state. At the same time, because the two clamping rods 31 inside the rotating cylinder 22 clamp the copper foil flash 81, the middle part of the copper foil flash 81 will be pulled by the two pairs of clamping rods 31, and A breakage occurs; as the rotating cylinder 22 rolls along the edge of the pressing plate 8 and is clamped by the clamping rods 31, the protruding copper foil burrs 81 on the edge of the pressing plate 8 will separate from the pressing plate 8 along the movement of the rotating cylinder 22 and be wound onto a pair of clamping rods 31; when the two mating blocks 11 separate to a predetermined distance, the clamping rods 31 will tear off all the copper foil burrs 81 of the pressing plate 8, and each pair of clamping rods 31 will enter between the corresponding two push rods 51. The upper push rod 51 in each pair of push rods 51 is also located between the rolled copper foil burrs 81 and the end face of the rotating cylinder 22. At this time, the stage of tearing off the copper foil burrs 81 is completed.

[0041] Waste discharge stage: such as Figures 1-8 As shown, before the two rotating cylinders 22 separate, each pair of push rods 51 moves along the rotating shaft 21 to a predetermined distance from the corresponding mounting rod 1. At this time, the projection of the clamping rod 31 along the length direction of the mounting rod 1 is located between each pair of push rods 51. After the two rotating cylinders 22 separate, the copper foil flash 81 is wound around a pair of clamping rods 31. The upper push rod 51 of each pair of push rods 51 is located between the end face of the rotating cylinder 22 and the rolled copper foil flash. When each pair of push rods 51 completely removes the copper foil flash 81 on the side corresponding to the pressing plate 8, each pair of clamping rods 31 enters between the corresponding two push rods 51, and the vertical distance between the two push rods 51 and the corresponding clamping rod 31 is less than the outer diameter of the rolled copper foil flash 81 at this time. After that, each pair of push rods 51 moves away from the corresponding mounting rod 1 along the rotating shaft 21, thereby pushing the rolled copper foil flash 81 away from the clamping rod 31.

[0042] Material unloading stage: The pressed plate 8 after the copper foil burr 81 has been removed is directly fed into the trimming process by the clamping mechanism 4; the two mounting blocks 6 separate in opposite directions at the same time, driving the corresponding two rotating cylinders 22 to abut against each other. The above operation can be repeated to remove the copper foil burr 81 from the next pressed plate 8.

[0043] Through the setting of the mounting blocks 6, the connecting rods 61, the mounting rods 1, the matching blocks 11, and the cooperation of the rotating shafts 21, the gearwheels 23 and the racks 24, the two mounting blocks 6 can convert the relative approaching or separating stroke of the two mounting blocks 6 into the relative approaching or separating stroke of the two matching blocks 11 along the mounting rods 1, and make the rotating cylinders 22 and the clamping rods 31 in the rotating cylinders 22 rotate with the movement of the matching blocks 11. When the rotating cylinders 22 move, the moving direction of the rotating cylinders 22 is always consistent with the length direction of the copper foil burrs 81, and the clamping rods 31 in each rotating cylinder 22 are perpendicular to the edge of the pressing plate 8. When the clamping rods 31 clamp the copper foil burrs 81, the two rotating cylinders 22 rotate and separate, and the copper foil burrs 81 will separate from the edge of the pressing plate 8 and be automatically wound on the clamping rods 31, so that the stable removal of the copper foil burrs 81 is effectively realized, and the problems of the separation of the base material or the copper foil burrs 81 caused by the uneven force and the uncertain angle of tearing can be effectively avoided. Meanwhile, through the setting of the push rods 51 and the cooperation of the push rods 51 and the clamping rods 31, the clamping rods 31 can automatically separate the wound copper foil burrs 81 from the clamping rods 31 after the clamping rods 31 remove all the copper foil burrs 81, so that the degree of automation is high, the removal efficiency of the copper foil burrs 81 can be effectively improved, and the production efficiency of the PCB board is improved.

[0044] Specifically, as shown in Figures 1-3 , the bottom of the mounting block 6 is connected to a driving block 65, and the base plate 9 horizontally supports a bidirectional screw rod 66 which is perpendicular to the mounting rod 1 and located below the mounting rod 1. The two driving blocks 65 are respectively threaded to the two opposite segments of the bidirectional screw rod 66, and one end of the bidirectional screw rod 66 is connected to a motor 67. The movement of the two mounting blocks 6 is driven by the cooperation of the motor 67 and the bidirectional screw rod 66, so that the two mounting blocks 6 have high movement stability and synchronization, thereby effectively ensuring the stability of the copper foil burrs 81.

[0045] Embodiment 2

[0046] As a further embodiment of the above-mentioned embodiment 1, as shown in Figure 3 , Figure 8 , Figure 10 , the two pairs of push rods 51 corresponding to the mounting rods 1 are respectively connected to a slide rod 52 which is parallel to the rotating shaft 21 and faces the other mounting rod 1. Each slide rod 52 is slidably arranged in a mounting seat 53, and the mounting seat 53 is arranged on the top surface of the base plate 9. The two slide rods 52 are connected by a cross rod 54 which is parallel to the mounting rod 1, and the slide rod 52 and the cross rod 54 are located below the clamping rod 31. A first spring 55 is sleeved on the slide rod 52 and connected between the cross rod 54 and the mounting seat 53. When the first spring 55 is in a natural state, the push rod 51 and the corresponding mounting rod 1 are spaced apart by a predetermined distance.

[0047] As shown in Figures 1-6As shown, each of the two mounting blocks 6 is connected to a push rod 62 that is parallel to the rotating shaft 21 on its opposite side; when the mounting block 6 drives the corresponding clamping rod 31 to enter between the two push rods 51 and the first spring 55 is in its natural state, the end of the push rod 62 passes between the two rotating cylinders 22 and abuts against the corresponding crossbar 54.

[0048] When applying, such as Figures 1-7 As shown, the first spring 55 is in its natural state, and under the drive of the mounting block 6, the clamping rod 31 clamps the rolled copper foil flash 81 and enters between the corresponding two push rods 51. At this time, the end of the top rod 62 on the mounting block 6 also synchronously abuts against the corresponding crossbar 54. The two mounting blocks 6 continue to move closer to each other synchronously, so that the clamping rod 31 that enters between the two push rods 51 moves along the length direction of the push rod 51. At the same time, the end of the top rod 62 moves against the crossbar 54, and the first spring 55 is stretched, so that the push rod 51 moves away from the corresponding mounting rod 1, thereby pushing the rolled copper foil flash 81 away from the clamping rod 31, realizing the automatic discharge of the copper foil flash 81.

[0049] By setting up the slide bar 52, mounting base 53, crossbar 54, and first spring 55, and with the cooperation of crossbar 54 and top bar 62, push bar 51 can automatically push the rolled copper foil burrs 81 away from clamping bar 31 after the mounting block 6 drives clamping bar 31 to wind all the copper foil burrs 81. There is no need to set up a separate drive structure to drive push bar 51 to move, which further improves the automation level of the removal device.

[0050] It should be noted that the copper foil pressed on the upper and lower surfaces of the inner core board is generally very thin, and the copper foil protruding from the edge of the pressing plate 8, i.e., the copper foil flash 81, is also relatively narrow. The clamping rod 31 can break the copper foil flash 81 with a small clamping force as the rotating cylinder 22 rotates and separates. At the same time, because the clamping force of the clamping rod 31 is small, it will not affect the push rod 51 from pushing the rolled copper foil flash 81 off the clamping rod 31.

[0051] Preferred, such as Figure 3 As shown, a dropping hole can be opened on the substrate 9 below the separation point of the copper foil burr 81 and the clamping rod 31, so that the separated copper foil burr 81 can automatically fall into the collection part through the dropping hole, thereby improving the collection efficiency.

[0052] Example 3

[0053] As a further implementation of the above embodiments 1-2, such as Figure 3 and Figure 4 As shown, the mounting rod 1 has support plates 12 at both ends, the support plates 12 are located on the top surface of the base plate 9, and two second springs 13 are sleeved on the mounting rod 1, which are connected between the corresponding support plates 12 and the mating blocks 11; when the second springs 13 are in the natural state, the two rotating cylinders 22 on the mounting rod 1 abut against each other.

[0054] As shown in Figures 1-3 The two sides of the mounting block 6 are provided with a strip-shaped slot 63 arranged along the moving direction thereof, and a movable block 64 is slidingly fitted in the strip-shaped slot 63. Each fitting block 11 is paired with a corresponding movable block 64. The two ends of the connecting rod 61 are rotationally connected with the corresponding fitting block 11 and movable block 64, respectively. That is, the rotation connection between the connecting rod 61 and the corresponding mounting block 6 is located on the movable block 64. The rotation axes corresponding to the two ends of the connecting rod 61 are both vertically arranged. When the movable block 64 abuts against the front end of the strip-shaped slot 63, the end of the top rod 62 is located at the rear end of the rotating cylinder 22. Here, the front end of the strip-shaped slot 63 refers to the end close to the corresponding mounting rod 1. Here, the rear end of the rotating cylinder 22 refers to the bottom end. When the movable block 64 abuts against the rear end of the strip-shaped slot 63 and the two rotating cylinders 22 abut against each other, the end of the top rod 62 is located at the front end of the rotating cylinder 22. Here, the rear end of the strip-shaped slot 63 refers to the end away from the corresponding mounting rod 1. Here, the front end of the rotating cylinder 22 refers to the cylinder mouth end.

[0055] As shown in Figures 3-7 Each rotating cylinder 22 is provided with a movable plate 25 arranged towards the cylinder mouth direction thereof. The bottom of the movable plate 25 is vertically provided with a guide rod 251 sliding through the cylinder wall of the rotating cylinder 22. One end of one clamping rod 31 is fixedly connected to the inner bottom surface of the rotating cylinder 22, and the other end of the other clamping rod 31 is connected to the movable plate 25. A third spring 252 is sleeved on the guide rod 251 and connected between the movable plate 25 and the inner wall of the rotating cylinder 22. When the third spring 252 is in a natural state, the two clamping rods 31 abut against each other. The side wall of the rotating cylinder 22 is provided with a communication slot 221 radially penetrating through the cylinder mouth end and the inner bottom surface thereof. The communication slot 221 is communicated with one side of the movable plate 25. The one side of the movable plate 25 is provided with a guide slot 26. When the two rotating cylinders 22 abut against each other, the two guide slots 26 corresponding to the two movable plates 25 are oppositely arranged. The top rod 62 is always located at the middle part of the two rotating cylinders 22. The end of the top rod 62 is connected to the middle part of a fitting rod 68 arranged in parallel to the mounting rod 1. The two ends of the fitting rod 68 are used to enter the corresponding guide slot 26 when the two rotating cylinders 22 abut against each other, so as to separate the clamping rod 31 connected to the movable plate 25 from the other clamping rod 31.

[0056] In application, as shown in Figures 1-7 The second spring 13 is in a natural state. The two rotating cylinders 22 abut against each other. The two mounting blocks 6 are separated away from each other, so that the movable blocks 64 are relatively moved to abut against the front ends of the strip-shaped slots 63. At this time, the fitting rod 68 at the end of the top rod 62 is located at the rear end of the rotating cylinder 22. The clamping rod 31 in each rotating cylinder 22 is in a clamping state.

[0057] After the two installation blocks 6 are synchronously moved towards each other, the installation blocks 6 will not drive the matching blocks 11 to move at the same time due to the action of the movable block 64, but the rotating cylinder 22 keeps abutting, and the movable block 64 moves to the rear end of the strip-shaped slot 63, and the installation blocks 6 move, so that the two ends of the matching rod 68 enter the guide slot 26 in the stroke of the relative movement of the movable block 64, and the linear movement of the matching rod 68 cooperates with the structure of the guide slot 26 to separate the clamping rods 31, and the matching rod 68 stays in the guide slot 26 to keep the clamping rods 31 in an open state, so that the feeding of the laminated plate 8 can be performed at this time.

[0058] After the laminated plate is fed to the predetermined position by the pinch mechanism 4, the two installation blocks 6 continue to move towards each other synchronously, and the rotating cylinder 22 still keeps abutting until the movable block 64 moves to the rear end of the strip-shaped slot 63, at which time the matching rod 68 moves out of the guide slot 26 and is located at the front end of the rotating cylinder 22, and the clamping rods 31 clamp the copper foil burr 81 under the action of the third spring 252.

[0059] The two installation blocks 6 continue to move towards each other, and since the movable block 64 has abutted against the rear end of the strip-shaped slot 63 at this time, the two matching blocks 11 will be separated synchronously with the movement of the two installation blocks 6, that is, the clamping rods 31 start to wind the copper foil burr 81, and at the same time, the end of the top rod 62 moves to the corresponding cross rod 54 to prepare to push the cross rod 54 to discharge the wound copper foil burr 81.

[0060] After the removal of the copper foil burr 81 is completed, the two installation blocks 6 are separated, and under the action of the second spring 13, the matching blocks 11 move towards each other synchronously, and the movable block 64 always abuts against the rear end of the strip-shaped slot 63 until the two rotating cylinders 22 abut, at which time the matching rod 68 is located at the front end of the rotating cylinder 22; the two installation blocks 6 continue to separate, the rotating cylinder 22 keeps abutting, and the movable block 64 moves to the front end of the strip-shaped slot 63, and at the same time, the installation blocks 6 pull the matching rod 68 back to the rear end of the rotating cylinder 22 through the guide slot 26, so as to process the next laminated plate 8.

[0061] Through the relative movement of the movable block 64 and the installation block 6, and the cooperation of the matching rod 68 and the guide slot 26, the two installation blocks 6 can automatically separate the clamping rods 31 when the two installation blocks 6 move towards each other and the rotating cylinder 22 is in an abutting state, so as to leave a feeding channel; at the same time, the clamping mechanism 3 can automatically clamp the copper foil burr 81 as the installation blocks 6 continue to move towards each other, thereby further improving the automation degree of the removal device.

[0062] Specifically, as shown in Figure 6 and Figure 7As shown, the guide groove 26 is sequentially provided with a first section 261 and a second section 262 along the direction of the mouth of the rotating cylinder 22, the first section 261 and the second section 262 are both horizontally arranged, and the first section 261 is located below the second section 262, one end of the first section 261 is communicated with one end of the movable plate 25, and one end of the second section 262 is communicated with the other end of the movable plate 25, and the other end of the first section 261 is transitionally communicated with the other end of the second section 262; the communication position of the other end of the second section 262 and the other end surface of the movable plate 25 is provided as a slope facing the corresponding clamping rod 31; when the third spring 252 is in a natural state and the rotating cylinder 22 is abutted, the projection of the cooperation rod 68 along the length direction of the jacking rod 62 is located in the first section 261 and on the slope of the other end surface of the movable plate 25; the bottom surface of the rotating cylinder 22 is further provided with a through groove 222 communicated with one end of the movable plate 25, and the through groove 222 is used for passing the cooperation rod 68.

[0063] When the rotating cylinder 22 is in the abutted state and the third spring 252 is in the natural state, the cooperation rod 68 is moved from the rear end to the front end of the rotating cylinder 22, and the cooperation rod 68 will first pass through the groove 222 and enter the first section 261, and then transitionally move from the first section 261 to the second section 262; since the second section 262 is located above the first section 261, when the cooperation rod 68 moves to the second section 262, the movable plate 25 can be pulled down, so that the separation of the clamping rod 31 is realized; when the cooperation rod 68 is moved from the front end to the rear end of the rotating cylinder 22, the cooperation rod 68 first abuts against the slope of the other end surface of the movable plate 25, and then sequentially passes through the second section 262 and the first section 261.

[0064] Embodiment 4

[0065] As a further embodiment of the above-mentioned embodiments 1-3, as shown in Figures 7-10 Although the copper foil burrs 81 can be directly pulled off by the clamping rod 31, the position where the copper foil burrs 81 are broken each time is inconsistent, which may affect the stability of the copper foil burrs 81. In order to ensure that the copper foil burrs 81 can be broken from the middle part before the rotating cylinder 22 is separated each time, and further ensure the stability of the removal of the copper foil burrs 81, a cutting assembly 7 can be erected above each mounting rod 1, which includes a cutter seat 71 provided on the base plate 9 and located at the middle position of the two pairs of clamping rods 31 corresponding to the mounting rod 1; each mounting rod 1 is provided with a mounting frame 74, the top of which is provided with a linear mechanism, the movable end of the linear mechanism is vertically downward and connected with a cutter holder 72 located above the cutter seat 71, and the cutter holder 72 is provided with a cutter blade 73; after the pressing plate 8 is fed, the copper foil burrs 81 are located between the cutter seat 71 and the cutter blade 73, and the linear mechanism drives the cutter holder 72 to move downward, so that the copper foil burrs 81 can be cut from the middle part, thereby ensuring that the copper foil burrs 81 can be broken from the middle part before the rotating cylinder 22 is separated each time, and improving the reliability of the removal device.

[0066] The above descriptions are only the preferred embodiment of the application, not intended to limit the application. Obviously, a person of ordinary skill in the art can make various modifications and variations to the application without departing from the spirit and scope of the application.
