Description

Technical Field

[0001] The present invention relates to the technical field of copper wire processing equipment, and particularly to a cutting device. Background Art

[0002] A heat sink is a device for dissipating heat from heat-generating electronic components in an electrical appliance, and is mostly in the shape of a plate, a sheet or multiple sheets, etc. Generally, a heat-conducting silicone grease needs to be applied to the contact surface between the electronic component and the heat sink during use, so that the heat generated by the component can be more effectively conducted to the heat sink and then dissipated into the surrounding air through the heat sink.

[0003] Heat sinks are usually assembled by heat sink assembly equipment, and the heat sink assembly equipment usually has the following functions: unwinding and sizing copper wires, cutting the copper wires into a fixed length, extracting the copper cores located inside the copper wires, and the copper wires from which the copper cores are extracted are conveyed to a welding station, where the copper wires are welded to metal copper sheets as a whole. However, the existing device for cutting copper wires has a relatively complex structure, and different cutting knives for cutting copper wires need to be driven by their own power mechanisms, resulting in low efficiency. Summary of the Invention

[0004] Based on this, in view of the problem of low efficiency of the existing device for cutting copper wires, it is necessary to provide a cutting device with higher efficiency for cutting copper wires.

[0005] A cutting device, comprising:

[0006] A base;

[0007] A first cutter assembly, which is reciprocally movable along a first direction and is arranged on the base;

[0008] A second cutter assembly, which is reciprocally movable along the first direction and is arranged on the base. During the reciprocal movement of the first cutter assembly and the second cutter assembly along the first direction, they can approach or move away from each other, and the material line can be cut off when the first cutter assembly and the second cutter assembly approach each other;

[0009] A rotating assembly, which is rotatably arranged on the base around a first rotation axis perpendicular to the first direction;

[0014] By setting the above-mentioned cutting device, initially, the first cutter assembly and the second cutter assembly are located at positions away from each other. At this time, the material line is conveyed between the first cutter assembly and the second cutter assembly. Then, the first driving member operates to drive the rotating assembly to rotate, indirectly driving the first cutter assembly and the second cutter assembly to approach each other, and cutting the material line during the approaching process. After cutting, the cut material line is removed. At the same time, the first driving member operates to drive the rotating assembly to rotate, indirectly driving the first cutter assembly and the second cutter assembly to move away from each other. After returning to the initial position, the above steps are repeated. In this way, only one first driving member can drive the actions of the first cutter assembly and the second cutter assembly simultaneously, thereby completing the cutting of the material line, without setting corresponding power mechanisms for the first cutter assembly and the second cutter assembly, simplifying the structure and improving the efficiency.

The moving block is reciprocally movably arranged on the base along the second direction. The third link is movably connected to the moving block, and the material grabbing member is arranged on the moving block for grabbing the material line.

[0022] In one embodiment, the third link includes a first connecting portion and a second connecting portion angularly connected to one end of the first connecting portion.

[0037] As Figure 1-3 shown, a cutting device provided by an embodiment of the present invention includes a base 11, a first cutter assembly 12, a second cutter assembly 13, a rotating assembly 14, a first driving member 15, a first connecting rod 16, and a second connecting rod 17.

[0038] The first cutter assembly 12 is reciprocally movable along a first direction and is disposed on the base 11.

[0039] The second cutter assembly 13 is reciprocally movable along the first direction and is disposed on the base 11. During the reciprocal movement of the first cutter assembly 12 and the second cutter assembly 13 along the first direction, they can approach or move away from each other. During the approaching process of the first cutter assembly 12 and the second cutter assembly 13, they can cut the material line 200.

[0040] The rotating assembly 14 is rotatably disposed on the base 11 about a first rotation axis perpendicular to the first direction.

[0041] The first driving member 15 is disposed on the base 11 and is in transmission connection with the rotating assembly 14.

[0042] One end of the first connecting rod 16 is hinged to the first cutter assembly 12, and the other end is hinged to the rotating assembly 14.

[0043] One end of the second connecting rod 17 is hinged to the second cutter assembly 13, and the other end is hinged to the rotating assembly 14.

[0044] The hinge axis of the first connecting rod 16 and the second connecting rod 17 is parallel to the first rotation axis.

[0045] Among them, the material line 200 is a copper wire or other linear materials that need to be cut. The first direction is Figure 1 the up and down direction shown, and the extending direction of the first rotation axis is Figure 1 the left and right direction shown.

[0046] By setting the above-mentioned cutting device, initially, the first cutter assembly 12 and the second cutter assembly 13 are located at positions far away from each other. At this time, the material line 200 is conveyed between the first cutter assembly 12 and the second cutter assembly 13. Then, the first driving member 15 operates to drive the rotating assembly 14 to rotate, indirectly driving the first cutter assembly 12 and the second cutter assembly 13 to approach each other, and cutting the material line 200 during the approaching process. After cutting, the cut material line 200 is removed. At the same time, the first driving member 15 operates to drive the rotating assembly 14 to rotate, indirectly driving the first cutter assembly 12 and the second cutter assembly 13 to move away from each other. After returning to the initial position, the above steps are repeated. In this way, only one first driving member 15 can drive the actions of the first cutter assembly 12 and the second cutter assembly 13 at the same time, thereby completing the cutting of the material line 200, without setting corresponding power mechanisms for the first cutter assembly 12 and the second cutter assembly 13, simplifying the structure and improving the efficiency.

[0047] It should be explained that taking the first connecting rod 16 hinged to the rotating assembly 14 as an example, the first connecting rod 16 being hinged to the rotating assembly 14 means that the first connecting rod 16 is rotatably connected to the rotating assembly 14 around a rotation axis. And the position where the first connecting rod 16 is hinged to the rotating assembly 14 has a hinge point, and the rotation axis passes through this hinge point. This rotation axis is the hinge axis of the first connecting rod 16 hinged to the rotating assembly 14.

[0048] In this way, it can be understood that the first connecting rod 16 has two hinge axes, and the second connecting rod 17 also has two hinge axes. The hinge axes of the first connecting rod 16 and the second connecting rod 17 are parallel to the first rotation axis. That is, after the first connecting rod 16 and the second connecting rod 17 are hinged to the rotating assembly 14, they will also rotate around the first rotation axis with the rotating assembly 14. And the other ends of the first connecting rod 16 and the second connecting rod 17 are hinged to the first cutter assembly 12 and the second cutter assembly 13 respectively, so as to realize the conversion of the rotation of the rotating assembly 14 into the movement of the first cutter assembly 12 and the second cutter assembly 13 in the first direction.

[0049] In some embodiments, the base 11 includes a bottom plate 112 and a mounting portion 114. The mounting portion 114 is provided on one side of the bottom plate 112. The first cutter assembly 12, the second cutter assembly 13, the rotating assembly 14, the first driving member 15, the first connecting rod 16 and the second connecting rod 17 are all provided on the mounting portion 114. The mounting portion 114 is supported by the bottom plate 112. The area of the bottom plate 112 is larger than that of the mounting portion 114, which can more stably support other structures in the device.

[0050] In practical applications, the material line 200 is conveyed in a second direction perpendicular to the first direction. The mounting portion 114 is provided with a notch for the material line 200 to pass through, so as to ensure the convenient installation of the above-mentioned structure and the convenient conveyance of the material line 200. Among them, the second direction isFigure 1 The left - right direction shown.

[0051] In some embodiments, the first cutter assembly 12 includes a first connecting plate 122 and a first cutter 124. The first connecting plate 122 is disposed on the base 11 to reciprocate along a first direction. The first link 16 is hinged to the first connecting plate 122. The first cutter 124 is disposed at one end of the first connecting plate 122 facing the second cutter assembly 13. The first cutter 124 can cut the material line 200 as the first connecting plate 122 and the second cutter assembly 13 approach each other.

[0052] Further, the second cutter assembly 13 includes a second connecting plate 132 and a second cutter 134. The second connecting plate 132 is disposed on the base 11 to reciprocate along the first direction. The second link 17 is hinged to the second connecting plate 132. The second cutter 134 is disposed at one end of the second connecting plate 132 facing the first connecting plate 122, and the second cutter 134 corresponds to the first cutter 124 in the first direction. The second cutter 134 can cut the material line 200 as the second connecting plate 132 and the first cutter 124 approach each other.

[0053] Combined with Figure 1 It can be understood that the first cutter 124 and the second cutter 134 corresponding to each other in the first direction means that during the reciprocating movement of the first connecting plate 122 and the second connecting plate 132 along the first direction, the surfaces of the adjacent cutting edges of the first cutter 124 and the second cutter 134 can be attached, or in other words, when the first cutter 124 and the second cutter 134 coincide in the first direction, the distance between the adjacent cutting edge surfaces is less than a preset gap. The preset gap may be caused by errors, as long as the material line 200 can be cut when the first cutter 124 and the second cutter 134 move to coincide in the first direction.

[0054] In some embodiments, a first linear guide 182 extending longitudinally along the first direction is provided on the base 11. First sliders 184 are fixedly provided on both the first connecting plate 122 and the second connecting plate 132. The first sliders 184 are slidably disposed on the first linear guide 182, so that the first connecting plate 122 and the second connecting plate 132 can reciprocate along the first direction and can approach or move away from each other during the reciprocating movement.

[0055] In some embodiments, the number of the first cutters 124 and the second cutters 134 is at least two, and each first cutter 124 corresponds to a second cutter 134 in the first direction. Thus, each time the first connecting plate 122 and the second connecting plate 132 approach each other, at least two first cutters 124 and at least two second cutters 134 can approach each other to cut at least two material lines 200 simultaneously.

[0056] In practical applications, at least two first cutting knives 124 are arranged at intervals in a third direction perpendicular to the first direction at one end of the first connecting plate 122 facing the second connecting plate 132. Correspondingly, at least two second cutting knives 134 are also arranged at intervals in the third direction at one end of the second connecting plate 132 facing the first connecting plate 122.

[0057] Specifically, the number of both the first cutting knives 124 and the second cutting knives 134 is two, and they are both arranged at intervals in the third direction. Among them, the first direction is Figure 2 the up-down direction shown, and the third direction is Figure 2 the left-right direction shown.

[0058] It should be noted that since the first cutting knives 124 and the second cutting knives 134 are arranged at intervals in the third direction, notches can be opened on both sides of the installation part 114 in the third direction to facilitate the conveying of the material line 200. Even a communication port penetrating through the opposite sides of the installation part 114 in the second direction can be opened, as long as it is ensured that other structures such as the wire rail will not affect the opening of the communication port, that is, it will not affect the conveying of the material line 200.

[0059] In addition, in the case where notches are opened on both opposite sides of the installation part 114 in the third direction, in order to enable the first connecting plate 122 and the second connecting plate 132 to move more stably in the first direction, there are four first wire rails 182. Correspondingly, there are also four first sliders 184. The four first wire rails 182 are symmetrically arranged in the first direction and the third direction respectively. The first connecting plate 122 and the second connecting plate 132 are respectively connected to the first wire rails 182 through the corresponding first sliders 184.

[0060] Please refer to Figure 3 and Figure 4 , in some embodiments, the distances between the hinge points of the first connecting rod 16 on the rotating assembly 14 and the hinge points of the second connecting rod 17 on the rotating assembly 14 and the first rotation axis are the same. In this way, during the rotation of the rotating assembly 14, the moving speeds of the first cutting knife assembly 12 and the second cutting knife assembly 13 are the same, which facilitates controlling the first cutting knife assembly 12 and the second cutting knife assembly 13 to approach and separate from each other, and further facilitates cutting the material line 200.

[0061] It can be understood that since the rotation of the rotating assembly 14 is converted into the movement of the first connecting plate 122 and the second connecting plate 132 in the first direction through the first connecting rod 16 and the second connecting rod 17, the rotational angular velocities of the ends of the first connecting rod 16 and the second connecting rod 17 connected to the rotating assembly 14 are the same.

[0062] Meanwhile, since the first rotation axis is perpendicular to the first direction, the larger the rotation radius of the ends of the first link 16 and the second link 17 hinged to the rotation assembly 14, the greater the displacement and speed of the first link 16 and the second link 17 in the first direction. Therefore, the rotation radii of the ends of the first link 16 and the second link 17 hinged to the rotation assembly 14 are the same.

[0063] Please refer to Figure 3 and Figure 4 , in some embodiments, the rotation assembly 14 includes a first gear 142 and a rotating shaft 144. The first gear 142 is rotatably arranged on the base 11 around the first rotation axis, and the first gear 142 is in transmission connection with the first driving member 15. The rotating shaft 144 is fixedly connected to one side of the first gear 142 along the second direction. One of the first link 16 and the second link 17 is hinged to the side of the first gear 142 away from the rotating shaft 144, and the other is hinged to the side of the rotating shaft 144 away from the first gear 142.

[0064] The first link 16 and the second link 17 are respectively connected to different structures, and the first link 16 and the second link 17 are spaced apart in the second direction. During the rotation of the first gear 142 and the rotating shaft 144 around the first rotation axis, the first link 16 and the second link 17 will not affect each other. In this way, the rotation assembly 14 can always rotate in the same direction to drive the first connecting plate 122 and the second connecting plate 132 to approach or separate from each other, without the need to drive the rotation assembly 14 to rotate forward and backward by the first driving member 15, reducing the requirements for the first driving member 15 and the design cost.

[0065] In some embodiments, the first driving member 15 includes a driving motor 152 and a second gear 154. The driving motor 152 is arranged on the base 11, and the second gear 154 is arranged at the driving end of the driving motor 152 to be rotatable around an axis under drive, and the second gear 154 meshes with the first gear 142, thereby driving the second gear 154 to rotate around the first rotation axis.

[0066] Please refer to Figure 1 , in some embodiments, the cutting device further includes a material grabbing assembly 19. The material grabbing assembly 19 is reciprocally movable along the second direction on the base 11, and is used for grabbing the material line 200 and approaching or separating from the first cutting assembly 12 and the second cutting assembly 13 in the second direction, so as to complete the conveying of the material line 200 along the second direction.

[0067] Further, the cutting device further includes a third connecting rod 21. The third connecting rod 21 is rotatably connected to the base 11 about a second rotation axis perpendicular to the first direction and the second direction. One end of the third connecting rod 21 is movably connected to the first cutting blade assembly 12 or the second cutting blade assembly 13, and the other end is movably connected to the material grasping assembly 19, and is used to drive the material grasping assembly 19 to approach or move away from the first cutting blade assembly 12 and the second cutting blade assembly 13 when the first cutting blade assembly 12 and the second cutting blade assembly 13 move away from or approach each other.

[0068] The material grasping assembly 19 is linked with the first cutting blade assembly 12 or the second cutting blade assembly 13 through the third connecting rod 21, and both the first cutting blade assembly 12 and the second cutting blade assembly 13 are driven by the same first driving member 15. In this way, the conveying of the material line 200 and the cutting of the material line 200 can be realized by one first driving member 15, without separately arranging a power mechanism for the conveying of the material line 200, further simplifying the structure, reducing the structural cost, and at the same time, the interlinkage of each mechanism also improves the efficiency.

[0069] In some embodiments, the material grasping assembly 19 includes a moving block 192 and a material grasping member 194. The moving block 192 is reciprocally movably arranged on the base 11 along the second direction. The third connecting rod 21 is movably connected to the moving block 192, and the material grasping member 194 is arranged on the moving block 192 and is used to grasp the material line 200.

[0070] Further, the material grasping member 194 includes a grasping state and a releasing state. When the material grasping member 194 is in the grasping state, the material grasping member 194 grasps the material line 200. When the material grasping member 194 is in the releasing state, the material grasping member 194 can release the material line 200. The material grasping member 194 can be switched between the grasping state and the releasing state during the moving process, so as to grasp the material line 200 and move it along the second direction and then release it, and can repeatedly process the material line 200, thereby realizing the conveying of the material line 200 during the reciprocating movement of the material grasping member 194 along with the moving block 192 along the second direction, and completing the loading of the material line 200.

[0071] In practical applications, the material grasping member 194 is a clamping jaw cylinder, and the clamping jaw cylinder has clamping jaws, and the clamping jaws are used to grasp the material line 200, so as to drive the material line 200 to move along the second direction and complete the loading.

[0072] Combined with Figure 1It should be noted that the successful feeding of the material line 200 means that one end of the material line 200 extends to a preset length on the discharge side of the first cutting knife assembly 12 and the second cutting knife assembly 13, and this preset length is the length of the finished product after the material line 200 is cut. Since the movement of the material gripping member 194 in the second direction is linked to the movement of the cutting knife assembly in the first direction, if the material gripping member 194 extends to the discharge side of the cutting knife assembly in the second direction and the material gripping member 194 is located between the first cutting knife assembly 12 and the second cutting knife assembly 13, it is necessary to consider that the material gripping member 194 will not affect the operation of the cutting knife assembly. If the material gripping member 194 always moves on the feeding side of the cutting knife assembly, there is no need to consider the material gripping member 194 affecting the operation of the cutting knife assembly. To reduce the design cost, the material gripping member 194 is preferably reciprocally moved on the feeding side of the cutting knife assembly.

[0073] Meanwhile, assuming that the material line 200 includes a head end and a tail end, the cutting of the material line 200 is from the head end to the tail end. After each cutting, a new head end will be formed on the material line 200, and this head end abuts against the cutting knife assembly. At this time, the reciprocating movement of the material gripping member 194 on the feeding side of the cutting knife assembly can drive the head end of the material line 200 to extend to the discharge side of the cutting knife assembly, and the reciprocating movement distance of the material gripping member 194 is the above-mentioned preset length.

[0074] Among them, the feeding side of the cutting knife assembly is the side where the material line 200 is conveyed in the second direction of the cutting knife assembly, that is Figure 1 the right side of the middle cutting knife assembly, and the corresponding discharge side is the side where the finished product of the preset length is formed in the second direction of the cutting knife assembly, that is Figure 1 the left side of the middle cutting knife assembly.

[0075] Please refer to Figure 1 and Figure 5 In some embodiments, a second linear guide 202 extending longitudinally in the second direction is provided on the moving block 192, and a second slider 204 is provided on the base 11. The second slider 204 is slidably engaged with the second linear guide 202, so that the moving block 192 is reciprocally moved in the second direction on the base 11.

[0076] In some embodiments, the third connecting rod 21 includes a first connecting portion 212 and a second connecting portion 214 angularly connected to one end of the first connecting portion 212. One end of the first connecting portion 212 connecting the second connecting portion 214 is rotatably connected to the base 11 around the second rotation axis. A first strip-shaped hole 211 is provided at the other end of the first connecting portion 212 away from the second connecting portion 214, and a second strip-shaped hole 213 is provided at the other end of the second connecting portion 214 away from the first connecting portion 212.

[0077] Further, the first cutter assembly 12 or the second cutter assembly 13 is provided with a first hinge rod 222. The cutting device further includes a second hinge rod 224 disposed on the moving block 192. The first hinge rod 222 is movably connected to the first strip-shaped hole 211, and the second hinge rod 224 is movably connected to the second strip-shaped hole 213.

[0078] In practical applications, the third link 21 is movably connected to the first connecting plate 122, that is, the first hinge rod 222 is disposed on the first connecting plate 122.

[0079] Please refer to Figure 1 and Figure 6 , in some embodiments, the cutting device further includes a guide block 23. The guide block 23 is provided with a guide hole 232 penetrating through its opposite sides along a second direction perpendicular to the first direction. The guide block 23 is disposed on the base 11 and is located on the feeding side of the first cutter assembly 12 and the second cutter assembly 13. The material line 200 is threaded through the guide hole 232, so as to guide the conveyance of the material line 200, ensure that the material line 200 corresponds to the cutter, and cut the material line 200 during the approach of the cutter.

[0080] Please refer to Figure 1 and Figure 7 , in some embodiments, the cutting device further includes a first clamping assembly 24 and a second clamping assembly 25. The first clamping assembly 24 and the second clamping assembly 25 are respectively disposed on opposite sides of the first cutter assembly 12 and the second cutter assembly 13 along the second direction, and are used for clamping the material line 200, so as to ensure that the material line 200 remains taut after successful feeding of the material line 200, that is, after the leading end of the material line 200 extends to a preset length on the discharging side of the cutter assembly, which facilitates the cutter to cut the material line 200.

[0081] Further, the first clamping assembly 24 includes a support plate 242, an upper pressing plate 244 and a second driving member 246. The support plate 242 and the second driving member 246 are both disposed on the base 11. The upper pressing plate 244 is in transmission connection with the second driving member 246, and is driven to reciprocate along the first direction, so as to approach or move away from the support plate 242.

[0082] During the conveyance of the material line 200, it passes between the support plate 242 and the upper pressing plate 244. After successful feeding of the material line 200, the second driving member 246 drives the upper pressing plate 244 to approach the support plate 242, so as to clamp and fix the material line 200 between the support plate 242 and the upper pressing plate 244. Specifically, the second driving member 246 is a cylinder or an electric cylinder, etc.

[0083] In some embodiments, the second clamping assembly 25 includes a clamping jaw, and the clamping jaw is used for clamping the leading end of the material line 200 extending to the discharging side of the cutter assembly.

[0084] It should be noted that the second clamping assembly 25 can also be a jaw cylinder or other power mechanism cooperating with a jaw, as long as it can clamp and fix the head end of the material line 200.

[0085] For the convenience of understanding the technical solution of the present invention, the working process of the cutting device in the above embodiment is described herein:

[0086] Initially, the first cutting knife assembly 12 and the second cutting knife assembly 13 are in positions far away from each other, and the material grabbing member 194 is in a released state. Then, the first driving member 15 acts to drive the first cutting knife assembly 12 and the second cutting knife assembly 13 to approach each other. At the same time, the material grabbing member 194 moves away from the cutting knife assembly along the second direction. After moving to a preset position, the material grabbing member 194 is converted from the released state to the grabbing state, and grabs the material line 200.

[0087] Next, the first driving member 15 continues to act to drive the first cutting knife assembly 12 and the second cutting knife assembly 13 to move away from each other. The material grabbing member 194 drives the material line 200 to feed. After the material line 200 is successfully fed, the second driving member 246 acts to press down the upper pressing plate 244 to clamp the material line 200, and the second clamping assembly 25 also clamps the head end of the material line 200.

[0088] The first driving member 15 continues to act to drive the first cutting knife assembly 12 and the second cutting knife assembly 13 to approach each other until the material line 200 is cut off, completing the cutting of the material line 200.

[0089] It can be understood that since there are at least two first cutting knives 124 and second cutting knives 134 to cut at least two material lines 200 simultaneously, the corresponding guide blocks 23, material grabbing assemblies 19, third connecting rods 21, first clamping assemblies 24, and second clamping assemblies 25 are all the same in number as the first cutting knives 124 and second cutting knives 134, so as to realize the automatic feeding and cutting process of at least two material lines 200 simultaneously.

[0090] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0091] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
