Description

Technical Field

[0001] The invention belongs to the technical field of core board cutting, and in particular relates to a core board cutting device. Background Art

[0002] The core board is made of copper foil, pre-impregnated glass fiber cloth (PP), and copper foil laminated together. Cutting is done using a cutter. The cutter consists of an upper cutter and a lower cutter. The core board is placed between the upper and lower cutters, and the upper cutter descends to cut the core board.

[0003] However, in practice, it was found that one of the edges of the cut surface of the core board after being cut by a cutter had severe burrs. The burrs were caused by the tearing between the copper foil and the PP. Severe burrs would affect the quality of subsequent finished products. Summary of the Invention

[0004] The purpose of this application is to provide a core board cutting device to solve the above-mentioned technical problems existing in the prior art.

[0005] This application is implemented as follows: An embodiment of the present application provides a core board cutting device, comprising a guide mechanism, and a restraining member, a cutting assembly, and a second clamping assembly arranged along a first direction, the first direction being parallel to a horizontal plane; the cutting assembly comprises a first cutter and a second cutter arranged along a gravity direction, the first cutter being located above the second cutter, and the first cutter and the second cutter being arranged side by side in the first direction, and the first cutter being controllably moved toward the second cutter along the gravity direction to cut the core board located therebetween; the restraining member is used to restrain the position of the core board in the gravity direction to prevent the core board from moving upward during the cutting process, the second clamping assembly is used to clamp the core board, and in the first direction, the restraining member is arranged closer to the first cutter relative to the second cutter, the restraining member cooperates with the guide mechanism for guidance, and the track extension direction of the guide mechanism is the gravity direction.

[0006] The technical solution adopted by the present invention can achieve the following beneficial effects: In the present application, when the core board is cut, the second clamping assembly clamps the core board, and the restraining member restrains the position of the core board in the direction of gravity. The first cutter approaches the second cutter to cut the core board. The middle PP and the lower copper foil are broken first under the action of the second cutter, followed by the upper copper foil. Before the first cutter cuts the upper copper foil, it is pressed against the upper copper foil, and the core board as a whole cannot move upward under the restraining action of the restraining member. Therefore, the separation of the upper copper foil and the middle PP caused by the rotation of the core board around the first cutter can be avoided. The separation of the copper foil and the PP is suppressed, thereby suppressing the generation of burrs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0010] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0011] In the related art, when cutting the core board 500, the cutting device used is referenced Figure 1 As shown, the cutting device includes an upper cutter 10 and a lower cutter 20 arranged opposite to each other, a support plate 40 is provided on the left side of the cutter, and a clamping assembly 30 is provided on the right side. The core board 500 to be cut is placed on the support plate 40, and the core board 500 extends between the upper cutter 10 and the lower cutter 20 and is clamped and fixed by the clamping assembly 30. When the cutters are used to cut the core board 500, the upper cutter 10 moves downward and abuts against the surface of the core board 500. The upper cutter 10 continues to move downward and cooperates with the lower cutter 20 to cut the core board 500. At the same time, the support plate 40 is squeezed and moved downward synchronously by the upper cutter 10.

[0012] However, one edge of the cut surface of the core plate 500 has severe burrs. Figure 2 As shown, the core board 500 is divided into two parts after being cut, and has two cutting surfaces. Both cutting surfaces have an upper edge and a lower edge. These four edges are named, and the edge marked as b will have burrs.

[0013] The burrs are actually caused by the separation of copper foil and PP. Some technologies grind the burrs after cutting, but this treatment method cannot completely solve the burr problem. It still affects subsequent products and reduces the cutting efficiency of the core board 500.

[0014] The burrs appear during the cutting process of the core plate 500. To solve the burr problem, the inventors have carefully studied the cutting process of the core plate 500. The cutting process of the core plate 500 can be referred to Figure 3 and Figure 4 shown.

[0015] During the cutting process, the PP in the middle of the core board 500 and the lower copper foil break first. As the upper cutter 10 continues to press down, the contact point between the core board 500 and the upper cutter 10 is stressed. Since the left side of the core board 500 is not fixed and is a free side with no movement restrictions, the downward movement of the upper cutter 10 will cause the left core board 500 to rotate around the blade of the upper cutter 10. Since the copper foil has a certain degree of ductility, the rotation of the left core board 500 will separate the upper copper foil from the PP before the upper copper foil breaks, thus producing burrs. This is Figure 2The reason why the edge marked b produces burrs is that the edge is torn and is in a free state, so burrs appear.

[0016] exist Figure 2 Among the other three edges, the edge marked a is pressed and cut by the upper cutter 10 and fixed by the clamping assembly 30 on the right. Although the edge marked c is torn, it is tightly fixed at the position of the lower cutter 20. The edge marked d is in a free state, but is pressed and cut by the lower cutter 20. No burrs will appear on these three edges.

[0017] In view of this, the embodiment of the present application provides a core board cutting device, referring to Figures 5 to 7 and Figure 11 As shown, the cutting device constrains and limits the core board 500 to prevent the core board 500 from rotating during the cutting process, which would cause the copper foil and PP to separate and produce burrs.

[0018] The cutting device includes a guide mechanism 400, as well as a restraining member, a cutting assembly 200, and a second clamping assembly 300 arranged along a first direction parallel to a horizontal plane. The restraining member and the second clamping assembly 300 are located on either side of the cutting assembly 200. The second clamping assembly 300 is used to clamp the core plate 500, stabilizing its position and allowing the cutting assembly 200 to steadily cut the core plate 500.

[0019] The cutting assembly 200 includes a first cutting blade 210 and a second cutting blade 220 arranged along the direction of gravity. Figure 10 As shown, the first cutter 210 is located above the second cutter 220, and the first cutter 210 and the second cutter 220 are arranged side by side in the first direction. The first cutter 210 can be controlled to move toward the second cutter 220 along the direction of gravity to cut the core board 500 located therebetween.

[0020] During the cutting process, the first cutter 210 moves downward along the direction of gravity, and the first cutter 210 and the second cutter 220 are arranged side by side in the horizontal direction to avoid the first cutter 210 colliding with the second cutter 220 during the process of cutting the core board 500, causing damage to the blade of the first cutter 210 or the second cutter 220.

[0021] The restraining member is used to restrain the position of the core plate 500 in the direction of gravity, preventing the core plate 500 from moving upward during the cutting process. The second clamping assembly 300 is used to clamp the core plate 500. In the first direction, the restraining member is arranged closer to the first cutter 210 relative to the second cutter 220. The first cutter 210 and the second cutter 220 are arranged side by side in the first direction, and the distances between the two cutters and the restraining member are also different. Compared with the second cutter 220, the restraining member is arranged closer to the first cutter 210. With respect to the second clamping assembly 300 located on the other side of the cutting assembly 200, the second clamping assembly 300 is arranged closer to the second cutter 220.

[0022] The restraint cooperates with the guide mechanism 400, the track extension direction of the guide mechanism 400 is the gravity direction, and the restraint can move along the track extension direction of the guide mechanism 400 to adjust the position of the restraint, so that the restraint can restrain the position of the core plate 500 in the gravity direction.

[0023] When using the cutting device to cut the core board 500, the core board 500 is placed between the first cutter 210 and the second cutter 220. The second clamping assembly 300 clamps the core board 500. The first cutter 210 moves downward, close to the second cutter 220, and the first cutter 210 presses against the core board 500, cooperating with the second cutter 220 to complete the cutting of the core board 500. The middle PP and the lower copper foil are first broken by the cutting action of the second cutter 220, followed by the upper copper foil.

[0024] After the lower copper foil and PP are broken and before the upper copper foil is broken, the first cutter 210 is pressed against the upper copper foil, and the first cutter 210 continues to move downward. Since the restraining member can restrain the position of the core board 500 in the direction of gravity, preventing the core board 500 from moving upward, even if the first cutter 210 continues to move downward, the core board 500 has a tendency to rotate with the blade of the first cutter 210 as the rotation axis, but due to the restraint of the restraining member, the core board 500 cannot move, resulting in the core board 500 being unable to rotate, thereby preventing the core board 500 from rotating with the blade rotation axis of the first cutter 210, and preventing the upper copper foil from separating from the PP. The separation of the copper foil and PP is suppressed, thereby suppressing the generation of burrs.

[0025] The cutting device provided in the embodiment of the present application limits the position of the core board 500 during the cutting process, changes the force mode of the cut position of the core board 500, avoids the cut position from being torn, and avoids the appearance of burrs on the core board 500 during the cutting process of the core board 500. There is no need for subsequent processing of the burrs, which is beneficial to improving the cutting effect of the core board 500 and the overall production efficiency of the PCB.

[0026] In some embodiments, reference Figure 11As shown, the restraining member is a pressing assembly 600, which is used to provide a downward pre-tightening force for the core panel 500. When cutting the core panel 500, the core panel 500 is located between the first cutter 210 and the second cutter 220. The second clamping assembly 300 clamps the core panel 500, and when the second core panel 500 contacts the second cutter 220, the pressing assembly 600 presses against the core panel 500, providing a downward pre-tightening force for the core panel 500.

[0027] Under the action of the preload force, the core plate 500 is slightly bent. When the first cutter 210 cuts the bent core plate 500, the core plate 500 is subjected to the preload force of the pressing assembly 600, which causes the core plate 500 to move downward, thereby reducing the space in which the core plate 500 can rotate and preventing the core plate 500 from rotating under the cutting of the first cutter 210.

[0028] If only the pressing assembly 600 is provided to limit the position of the core plate 500, the pressing assembly 600 does not provide a pre-tightening force on the core plate 500, and the core plate 500 will not bend, and the core plate 500 will still have a certain range of movement. When the first cutter 210 cuts the core plate 500, after the first cutter 210 pushes the core plate 500 to move, the rotational space of the core plate 500 is not restricted, and the core plate 500 will still rotate to a certain extent, resulting in burrs.

[0029] Therefore, the pressing assembly 600 needs to provide a downward pre-tightening force on the core plate 500, causing the core plate 500 to bend, thereby limiting the rotation space of the core plate 500 and preventing the core plate 500 from rotating when the first cutter 210 cuts the upper copper foil. After the upper copper foil breaks, the core plate 500 has been cut. Even if the first cutter 210 continues to move downward, causing the core plate 500 to rotate, the cut edge will not have burrs.

[0030] The pressing assembly 600 can be in the form of a cylinder, a spring, a gravity, an electromagnetic force, or a vacuum adsorption mode to control the core plate 500 and provide a downward pre-tightening force for the core plate 500. It should be noted that when the vacuum adsorption mode is selected, the pressing assembly 600 needs to be located below the core plate 500 to adsorb the core plate 500, thereby providing a downward pre-tightening force for the core plate 500, and the pressing assembly 600 needs to be able to move downward in coordination with the pressure of the first cutter 210 and the position change of the first cutter 210.

[0031] The guide mechanism 400 is mainly used to adjust the position of the pressing assembly 600 and the magnitude of the pre-tightening force applied by the pressing assembly 600 to the core plate 500 .

[0032] In some embodiments, reference Figures 5 to 7As shown, the restraining member is a first clamping assembly 100 , which is used to clamp the core plate 500 . The first clamping assembly 100 can clamp the core plate 500 and move along the track extension direction of the guide mechanism 400 .

[0033] When cutting the core board 500, the first clamping assembly 100 and the second clamping assembly 300 are both clamped on the core board 500. After the lower copper foil and PP are broken and before the upper copper foil is broken, the first cutter 210 is pressed against the upper copper foil and continues to move downward, driving the portion of the core board 500 clamped by the first clamping assembly 100 to move downward synchronously, thereby preventing the core board 500 from rotating about the blade rotation axis of the first cutter 210 and preventing the upper copper foil from separating from the PP. The separation of the copper foil and PP is suppressed, thereby suppressing the generation of burrs.

[0034] By using the first clamping assembly 100 to clamp the core board 500 located on the side of the first cutter 210, when the first cutter 210 cuts the core board 500, the position of the core board 500 is fixed by the first clamping assembly 100, and the first clamping assembly 100 and the first cutter 210 move downward synchronously to prevent the upper copper foil of the core board 500 from separating from the PP.

[0035] The guide mechanism 400 primarily provides a track for the first clamping assembly 100, enabling it to move in a predetermined direction under the pressure of the first cutter 210, thereby preventing the core plate 500 from rotating on the side of the first cutter 210. The track of the guide mechanism 400 extends in the direction of gravity, the same direction as the first cutter 210 descends.

[0036] In some embodiments, the guide mechanism 400 may further include a power device to control the movement of the first clamping assembly 100 .

[0037] The first clamping assembly 100 fixes the core plate 500 by clamping, preventing the core plate 500 from moving. The first clamping assembly 100 can be implemented in various ways. In some embodiments, the first clamping assembly 100 can be configured as a spring clamp structure, clamping the core plate 500 by the elastic force of a spring.

[0038] In some embodiments, the first clamping assembly 100 includes a first clamping portion 110 and a second clamping portion 120 arranged along the direction of gravity. Figure 8 As shown, when clamping the core plate 500, the two clamping portions are located on both sides of the core plate 500. At least one of the first clamping portion 110 and the second clamping portion 120 can move toward the other in the direction of gravity, shortening the distance between them, thereby clamping the core plate 500 located therebetween. Either the first clamping portion 110 or the second clamping portion 120 can be movable, or both can be movable.

[0039] After the two clamping parts are close to each other and pressed against the core plate 500, a constant clamping force of the two clamping parts can be maintained by a heavy object, or the position of the core plate 500 can be fixed by vacuum adsorption in the form of a vacuum suction chamber.

[0040] In some preferred embodiments, the first clamping portion 110 includes a first clamping plate 111 and a first driving mechanism 112. Figure 8 As shown, the first driving mechanism 112 is connected to the first clamping plate 111 and is used to drive the first clamping plate 111 to move toward the second clamping portion 120. The first driving mechanism 112 provides driving force for the first clamping plate 111 to drive the first clamping plate 111 to move. At the same time, the first driving mechanism 112 can also make the first clamping plate 111 press against the second clamping portion 120, thereby clamping the core plate 500. The first driving mechanism 112 can be in the form of a cylinder, an electromagnetic force, a spring, etc.

[0041] And / or, similar to the first clamping portion 110, the second clamping portion 120 includes a second clamping plate 121 and a second driving mechanism 122, Figure 8 As shown, the second driving mechanism 122 is connected to the second clamping plate 121, and is used to drive the second clamping plate 121 toward the first clamping part 110. The second driving mechanism 122 provides driving force for the second clamping plate 121. The second driving mechanism 122 is similar to the first driving mechanism 112, and can also be in the form of a cylinder, an electromagnetic force, a spring, etc.

[0042] The first driving mechanism 112 and the second driving mechanism 122 are generally directly fixed to the overall frame of the cutting device, and the cutting assembly 200 is also installed on the frame.

[0043] The first clamping assembly 100 further includes a mounting plate 130, referring to Figure 8 As shown, the first clamping portion 110 and the second clamping portion 120 are both mounted on a mounting plate 130. The mounting plate 130 cooperates with the guide mechanism 400 to guide and control the movement of the mounting plate 130 in the direction of gravity. The mounting plate 130 as a whole moves along the guide mechanism 400, and the first clamping portion 110 and the second clamping portion 120 on the mounting plate 130 change with the position of the mounting plate 130.

[0044] By setting up the mounting plate 130, when the first clamping assembly 100 moves synchronously with the first cutter 210, only the mounting plate 130 will be driven to move relative to the guide mechanism 400, and the relative positions of the first clamping part 110 and the second clamping part 120 and the mounting plate 130 will not change. Therefore, the clamping of the core plate 500 by the first clamping part 110 and the second clamping part 120 will not change, thereby avoiding the occurrence of unstable clamping of the core plate 500 by the first clamping assembly 100 during the synchronous movement of the first clamping assembly 100 and the first cutter 210.

[0045] In some embodiments, there are multiple first clamping parts 110, all of which are arranged in a straight line, and the arrangement direction of all of the first clamping parts 110 is parallel to the length direction of the first cutting knife 210; there are multiple second clamping parts 120, all of which are arranged in a straight line, and the arrangement direction of all of the second clamping parts 120 is parallel to the length direction of the first cutting knife 210.

[0046] The core plate 500 is relatively large overall, and a combination of multiple first clamping portions 110 and second clamping portions 120 can be optionally provided to clamp the core plate 500. The length direction of the first cutter 210 is actually the direction of the blade of the first cutter 210. The core plate 500 is clamped in the direction of the blade of the first cutter 210, which provides a more stable fixation of the core plate 500 and effectively prevents the core plate 500 from rotating around the blade of the first cutter 210.

[0047] When the first clamping assembly 100 also includes a mounting plate 130, multiple first clamping parts 110 and second clamping parts 120 are all installed on the mounting plate 130. The mounting plate 130 is used to unify the movement of all components on the guide mechanism 400, so that the first clamping assembly 100 as a whole can follow the movement of the first cutting knife 210 while stably clamping the core plate 500.

[0048] In some embodiments, the first clamping portion 110 is positioned above the second clamping portion 120. The second clamping plate 121 of the second clamping portion 120 is positioned relative to the first clamping portion 110 and adjacent to the second cutter 220. The second clamping plate 121 and the second cutter 220 form a gap in the first direction for the first cutter 210 to pass through. The second clamping plate 121 is positioned below the core panel 500 and is used to cooperate with the first clamping portion 110 to clamp the core panel 500 and also to support the core panel 500. The second clamping plate 121 is positioned closer to the first cutter 210 than the first clamping portion 110. The first clamping portion 110 is not present above the portion of the second clamping plate 121 adjacent to the first cutter 210. This portion of the second clamping plate 121 serves only to support the core panel 500.

[0049] When the first cutter 210 cuts the core board 500, the first cutter 210 presses against the core board 500, thereby pushing the core board 500 downward in the direction of gravity. The closer the part of the second clamping plate 121 is to the first cutter 210, the easier it is for the pressing force of the first cutter 210 to be transmitted to the first clamping assembly 100. After the first cutter 210 presses against the core board 500, the first clamping assembly 100 can more easily slide along the guide mechanism 400 to cooperate with the first cutter 210 to cut the core board 500. In addition, the second clamping plate 121 can support the core board 500 with the copper foil below and the PP in the middle already broken, thereby preventing the part of the core board 500 near the first cutter 210 from separating from the upper copper foil under the action of gravity due to the lack of support below.

[0050] The embodiment of the present application mainly avoids the appearance of burrs by keeping the position of part of the core board 500 on the side of the first cutting knife 210 stable and preventing the part of the core board 500 from rotating. The closer the first clamping assembly 100 is to the first cutting knife 210, the more stable the position of the core board 500 during cutting, and the less likely it is to rotate, shake, etc.

[0051] However, since the first cutter 210 needs to move up and down along the direction of gravity, the first cutter 210 and the base connected thereto have a certain volume. To prevent the first clamping portion 110 from interfering with the movement of the first cutter 210, a certain distance is required between the first clamping portion 110 and the first cutter 210. The second clamping portion 120 is located below the core plate 500, and a gap is reserved between the second clamping plate 121 of the second clamping portion 120 and the second cutter 220 for the first cutter 210 to pass through. Therefore, even if the second clamping plate 121 is close to the first cutter 210, it will not interfere with the movement of the first cutter 210.

[0052] The first cutter 210, the first clamping assembly 100, and the pressing assembly 600 are all capable of moving in the direction of gravity. Both the first clamping assembly 100 and the pressing assembly 600 cooperate with the guide mechanism 400, utilizing the tracks of the guide mechanism 400 to restrict their movement, allowing them to move only in the direction of gravity. The first cutter 210 also requires guidance and coordination with associated guide tracks to restrict its movement. In some embodiments, the first cutter 210 and the first clamping assembly 100 or the pressing assembly 600 share the guide mechanism 400. The first cutter 210 cooperates with the guide mechanism 400 for guidance, enabling it to move along the direction of the tracks of the guide mechanism 400 to move closer to or further from the second cutter 220. In other embodiments, a separate track may be provided to guide the first cutter 210.

[0053] The guide mechanism 400 can be set as a guide rail structure or a guide rod structure. The embodiment of the present application has no requirements for the specific setting form of the guide mechanism 400, as long as the guide mechanism 400 can provide a sliding track with a determined direction for the first clamping assembly 100.

[0054] In some embodiments of the present application, the second clamping assembly 300 includes a fixed plate 310 and a third clamping portion 320 arranged along the direction of gravity. The second clamping assembly 300 is entirely located on one side of the second cutter 220, with the fixed plate 310 positioned adjacent to the second cutter 220. Furthermore, the fixed plate 310 is fixed to a corresponding blade holder of the second cutter 220. The fixed plate 310 and the second cutter 220 maintain a constant position, and the surface of the fixed plate 310 is coplanar with the blade of the second cutter 220. After the core board 500 is placed on the fixed plate 310, it contacts the blade of the second cutter 220, facilitating subsequent cutting of the core board 500. The third clamping portion 320 can be controlled to move toward the fixed plate 310 along the direction of gravity to clamp the core board 500 between the fixed plate 310 and the second cutter 220.

[0055] After the second clamping assembly 300 clamps the core plate 500, its overall position remains unchanged, which is more conducive to the first cutter 210 cutting the core plate 500. At the same time, the structure of the third clamping part 320 is similar to the first clamping part 110 and the second clamping part 120. The fixing method and movement method of the core plate 500 can be set to the same structure. The third clamping part 320 includes a third clamping plate 321 and a third driving mechanism 322. Figure 9 As shown, the third driving mechanism 322 is connected to the third clamping plate 321 and is used to drive the third clamping plate 321 to move toward the fixed plate 310. After the third clamping plate 321 moves downward to clamp the fixed plate 310, the position of the third clamping plate 321 remains stable during the process of the first cutting knife 210 descending to cut the core board 500, and the position of the second clamping assembly 300 as a whole does not change with the descent of the first cutting knife 210.

[0056] In some embodiments, the cutting device further includes a support plate, which is located on one side of the first cutter 210 and is used to support the core board 500. The support plate also cooperates with the guide mechanism 400 to guide the core board 500. When the first cutter 210 is pressed against the core board 500 and cuts the core board 500, the support plate can move with the first cutter 210. At the same time, the support plate is hollowed out so as not to affect the direct contact between the first clamping assembly 100 or the pressing assembly 600 and the core board 500.

[0057] The present embodiment further provides a method for cutting a core plate 500, using the core plate 500 cutting device provided in the above embodiment. The specific steps are as follows: S10 : First, the core board 500 needs to be placed between the first cutter 210 and the second cutter 220 , and the position of the core board 500 to be cut is aligned with the first cutter 210 and the second cutter 220 .

[0058] S20: Then, the first clamping assembly 100 and the second clamping assembly 300 are used to clamp the core board 500 and fix the position of the core board 500. In this process, it can also be confirmed again whether the position where the core board 500 needs to be cut is aligned with the first cutter 210 and the second cutter 220.

[0059] S30: After the core board 500 is fixed, the first cutter 210 is driven to move toward the second cutter 220 to complete the cutting of the core board 500. During the cutting process of the core board 500, due to the clamping of the core board 500 by the first clamping assembly 100, this part of the core board 500 can only move in the direction of gravity and cannot rotate around the blade of the first cutter 210, thereby preventing the upper copper foil and the middle PP from splitting due to the rotation of the core board 500, thereby preventing burrs from appearing on the cut edge of the core board 500.

[0060] In step S20, the first cutter 210 can be driven to a preset position in advance to prepare for cutting the core panel 500. The preset position is a position close to the clamped core panel 500. The first cutter 210 can be lowered after the first clamping assembly 100 and the second clamping assembly 300 secure the core panel 500. Alternatively, the first cutter 210 can be lowered first and then the core panel 500 is clamped and secured.

[0061] In this application, by studying the reasons for the burrs on the cutting edges of the core board 500 and limiting the movement path of the core board 500 during the cutting process, the burrs on the cutting edges of the core board 500 are avoided, thereby improving the cutting quality and cutting efficiency of the core board 500.
