Description

Technical Field

[0001] This application relates to the field of material cutting technology, and in particular to a horizontal vibration cyclic cutting device for thermally conductive materials. Background Technology

[0002] In industrial production and daily life, the application of thermally conductive materials is becoming increasingly widespread. For example, in the fields of heat dissipation of electronic equipment and industrial heat exchange systems, materials with good thermal conductivity are needed to ensure the normal operation of equipment and improve energy efficiency. With the continuous advancement of technology, higher requirements are being placed on the processing precision and efficiency of thermally conductive materials. Especially in the cutting process of thermally conductive materials, the quality and speed directly affect the performance and production cycle of subsequent products. Efficient and precise cutting processes can improve the overall quality of products, reduce material waste, lower production costs, and thus promote the rapid development of related industries.

[0003] In the past, there were several conventional methods for cutting thermal conductive materials. One was manual cutting, where workers used ordinary tools and relied on experience and skill. This method was relatively flexible and could adapt to cutting irregular shapes. Another was a simple mechanical cutting method, which used a fixed cutting die or tool to perform a downward cutting motion on the thermal conductive material. In addition, there was a method that used linear guides and drive devices to move the tool in a straight line for cutting, which could ensure the straightness of the cut to a certain extent. At the same time, there were also methods that used rotating tools for circumferential cutting, suitable for cutting thermal conductive materials of certain specific shapes. These traditional methods have long been widely used in the field of thermal conductive material processing.

[0004] However, existing methods for cutting thermal conductive materials have significant drawbacks. Manual cutting is easily limited by the skill level and physical strength of workers, making it difficult to guarantee cutting accuracy and consistency, and the work efficiency is low. Simple mechanical cutting can only achieve cutting in one direction, which cannot meet the cutting requirements of complex shapes and high precision. Although the linear guide rail drives the tool to move in a straight line and the rotating tool moves in a circular motion, the tool's movement trajectory is relatively simple, which can easily lead to defects such as burrs and false edges. In particular, for oxide powder in thermal conductive materials, the single running trajectory of the cutting tool can easily cause rapid wear. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this application provides a horizontal vibration cyclic cutting device for thermally conductive materials, which can drive the cutting blade to vibrate and cut the thermally conductive material in an elliptical trajectory, thereby reducing the wear of the cutting blade and making it less likely for the cut product to have defects such as burrs and false edges.

[0006] This application is achieved through the following technical solution:

[0007] A horizontal vibration cyclic cutting device for thermally conductive materials, comprising:

[0008] The work platform is equipped with a cutting base plate for supporting the materials to be cut;

[0009] The cutting blade assembly includes a fixed blade holder arranged horizontally, a movable blade holder slidably connected to the fixed blade holder, and a cutting blade connected to the movable blade holder;

[0010] A cyclic vibration unit is configured to generate periodic vibrations in the horizontal direction to drive the moving tool holder to perform reciprocating motion in the horizontal direction.

[0011] A vertical drive mechanism drives the cutting blade assembly to reciprocate along the height direction.

[0012] By adopting the above technical solution, a vertical drive mechanism is set up to drive the fixed blade holder to reciprocate in the vertical direction. In conjunction with the cyclic vibration unit, the cutting blade moves in an elliptical trajectory, realizing the vibration cutting of thermally conductive materials. This produces a periodic "pecking" effect, which significantly reduces the surface pressure when the cutting blade is in continuous contact with the product, and reduces product deformation and edge collapse caused by cutting pressure. In particular, for oxide powder in high thermal conductivity materials, this cutting mode can solve the problem of blade wear between the cutting blade and the oxide powder in high thermal conductivity materials, and avoid defects such as burrs and false edges in the product during the cutting process. It can also solve the problem of some material breaking and fuzz when cutting fibrous materials, cotton materials and double-sided adhesive materials.

[0013] Optionally, the cyclic vibration unit includes a servo drive motor, an eccentric cam, and an elastic reset mechanism; the servo drive motor drives the eccentric cam to rotate, and the elastic reset mechanism generates periodic compression and reset under the push of the eccentric cam; the eccentric cam and the elastic reset mechanism cooperate to make the cutting blade reciprocate in the horizontal direction.

[0014] By adopting the above technical solution, a servo drive motor drives an eccentric cam to rotate, which, under the action of an elastic reset mechanism, drives the moving blade holder to reciprocate in the horizontal direction. In conjunction with the vertical drive mechanism, the cutting blade moves along an elliptical trajectory to achieve the cutting of heat-conducting materials. Similarly, when the eccentric cam rotates, due to its eccentric characteristics, the horizontal component velocity is different at different positions. This velocity variation law causes the load on the cutting blade to exhibit a gradual process during the cutting of heat-conducting materials. Traditional cutting methods may cause the cutting blade to be subjected to a large impact force instantaneously, which can easily cause excessive wear or even damage to the cutting blade. However, in this technical solution, the gradual process of the cutting blade load can greatly reduce the instantaneous impact force borne by the cutting blade.

[0015] Optionally, the elastic reset mechanism includes a spring and a spring fixing seat, the spring fixing seat being connected to the movable tool holder, and the movable tool holder being slidably connected to the fixed tool holder via a linear guide rail.

[0016] By adopting the above technical solution, the elastic reset component is placed between the fixed blade holder and the slide block and sleeved on the sliding guide rod. This eliminates the gap at the hinge, reduces the movement of the fixed blade holder, and improves the cutting accuracy. In addition, the elastic reset component can buffer the impact force generated when the fixed blade holder makes vertical reciprocating motion under the drive of the vertical drive mechanism, reduce device vibration and noise, and improve the stability of the cutting process and the service life of the equipment.

[0017] Optionally, a circulating sliding pin is connected to the spring fixing seat, the spring is sleeved on the circulating sliding pin, the circulating sliding pin contacts the eccentric cam under the elastic force provided by the spring, and the servo drive motor drives the eccentric cam to rotate, causing the circulating sliding pin to generate a periodic horizontal thrust.

[0018] By adopting the above technical solution, the working platform is equipped with a fixed blade holder and a linear guide rail. The moving blade holder reciprocates horizontally under the action of the cyclic vibration unit, and the vertical drive mechanism drives the fixed blade holder to reciprocate vertically. In conjunction with the cyclic vibration unit, the cutting blade moves in an elliptical trajectory to cut the heat-conducting material. The cyclic vibration unit realizes the reciprocating motion of the moving blade holder through a servo drive motor, an eccentric cam, a slide, and a cyclic sliding pin. A positioning shoulder is set at the head of the cyclic sliding pin, and a spring is sleeved on the cyclic sliding pin and placed between the positioning shoulder and the slide. This ensures that the head of the cyclic sliding pin is always in contact with the eccentric cam, ensuring the stable operation of the cyclic vibration unit. This allows the moving blade holder to reciprocate stably in the horizontal direction, thereby ensuring that the cutting blade moves in the expected elliptical trajectory and improving the stability and reliability of cutting the heat-conducting material.

[0019] Optionally, either the movable tool holder or the fixed tool holder is provided with a linear guide rail, and a linear bearing is provided inside the linear guide rail.

[0020] By adopting the above technical solution, the linear guide can stably support the sliding of the moving tool holder, making the moving tool holder move more smoothly; the detachable connection facilitates the installation and disassembly of the linear guide, making it convenient for later maintenance or replacement. Specifically, the linear guide can adopt a dovetail structure.

[0021] Optionally, a height adjustment mechanism is provided between the fixed blade holder and the movable blade holder, the height adjustment mechanism being used to adjust the distance between the cutting blade and the cutting base plate.

[0022] By adopting the above technical solutions, the height adjustment mechanism can adjust the distance between the cutting blade and the cutting base plate for different specifications of cutting materials, thereby enhancing the applicability of the device. Specifically, the height adjustment mechanism can be a screw adjustment mechanism, such as installing a precision lead screw between the fixed blade holder and the moving blade holder, and rotating the lead screw to drive the moving blade holder to move up and down; the height adjustment mechanism can also be a wedge mechanism, with a transverse adjustment bolt on the side of the fixed blade holder, pushing the wedge block (sloping slider) to move longitudinally, which is converted into the vertical displacement of the moving blade holder; the height adjustment mechanism can also be an eccentric wheel / cam mechanism. One height adjustment mechanism can be a gear-based system where an eccentric shaft is mounted on top of the moving tool post, and the rotating eccentric wheel directly raises or lowers the tool post. Alternatively, a rack can be fixed to the side of the moving tool post, and the height can be adjusted manually or by motor drive via a pinion gear, then locked with bolts. Another option is a multi-stage shim / block system where standard shims of different thicknesses are inserted between the contact surfaces of the fixed and moving tool posts, and the height is adjusted by adding or removing shims. A third option is a hydraulic / pneumatic adjustment system that uses a small hydraulic or pneumatic cylinder to raise the moving tool post, coupled with closed-loop control via a pressure sensor.

[0023] Optionally, the cutting blade is slidably connected to the movable blade holder, and the height adjustment mechanism includes an adjusting bolt threaded onto the movable blade holder, the lower end of which abuts against the clamping plate.

[0024] By adopting the above technical solution, the cutting blade can be fixed by the clamping plate, and the movable blade holder is equipped with a vertically arranged directional slide rail, specifically a T-shaped slide rail, so that the clamping plate can slide on it for easy position adjustment; the top of the clamping plate is provided with a T-shaped groove arranged along the length of the movable blade holder, which is adapted to the positioning part at the lower end of the adjusting bolt. The positioning part can rotate in the T-shaped groove, so that rotating the adjusting bolt can drive the clamping plate to move up and down, thereby adjusting the distance between the cutting blade and the work platform to achieve more precise cutting.

[0025] Optionally, a spring is provided between the movable blade holder and the cutting blade to drive the cutting blade upward.

[0026] By adopting the above technical solution, the distance between the cutting blade and the work platform can be adjusted by the downward pressure of the adjusting bolt, and the spring can eliminate the gap at the connection point, reduce the movement of the fixed blade holder, and improve the cutting accuracy.

[0027] Optionally, the vertical drive mechanism includes a main drive component, a transmission component disposed at the output end of the main drive component, and an elastic reset component; the transmission component drives the fixed tool holder to reciprocate along the height direction; further, preferably the main drive component can be a cylinder, motor, servo motor, or other drive component; the transmission component can be a gear transmission, cam transmission, crank-connecting rod transmission, or other transmission components.

[0028] By adopting the above technical solution, the main driving component can be a vertical drive motor, while the transmission component can adopt various structural forms, such as an eccentric turntable combined with a connecting rod, which pushes the sliding guide rod to move vertically in the guide hole of the guide seat, ultimately realizing the reciprocating motion of the fixed blade holder in the vertical direction. This structural design makes the eccentric shaft rotate in a circular motion while its velocity component in the vertical direction changes sinusoidally. When the eccentric shaft rotates, due to its eccentric characteristics, the vertical velocity component is different at different positions. This velocity change law causes the load on the cutting blade to present a gradual process during the cutting of thermally conductive materials. Traditional cutting methods may cause the cutting blade to be subjected to a large impact force instantaneously, which can easily cause excessive wear or even damage to the cutting blade. However, in this technical solution, the gradual process of the cutting blade load can greatly reduce the instantaneous impact force borne by the cutting blade.

[0029] Optionally, the vertical drive mechanism further includes a sliding guide rod and an elastic reset member; the fixed blade holder is connected to the transmission member through the sliding guide rod; the elastic reset member is sleeved on the sliding guide rod, with one end abutting against the cutting base plate and the other end abutting against the fixed blade holder.

[0030] By adopting the above technical solution, the work platform can be equipped with a guide seat, and the sliding guide rod can be slidably connected in the guide seat. The elastic reset component is placed between the fixed knife holder and the guide seat and sleeved on the push rod. This can eliminate the gap at the hinge, reduce the movement of the fixed knife holder, and improve the cutting accuracy. In addition, the guide seat can buffer the impact force generated when the fixed knife holder makes vertical reciprocating motion under the drive of the vertical drive mechanism, reduce device vibration and noise, and improve the stability of the cutting process and the service life of the equipment.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. This application can drive the cutting blade to vibrate and cut the thermally conductive material in an elliptical trajectory to generate a periodic "pecking" effect during the cutting process. This can significantly reduce the surface pressure when the cutting blade is in continuous contact with the product, reduce product deformation and edge collapse caused by cutting pressure, and improve product quality.

[0033] 2. This application allows for adjustment of the distance between the cutting blade and the work platform via a height adjustment mechanism, which helps improve the cutting accuracy of thermally conductive materials and avoids cutting problems caused by unsuitable cutting blade height;

[0034] 3. The device described in this application achieves automated cutting, avoiding the limitations of manual cutting due to skill level and physical strength, and improving work efficiency and consistency of cutting accuracy. Attached Figure Description

[0044] The technical solutions of various embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] Example 1

[0046] Reference Figures 1 to 3This application discloses a horizontal vibration cyclic cutting device for thermally conductive materials, comprising:

[0047] The work platform 1 is equipped with a cutting base plate 11 for supporting the material to be cut;

[0048] The cutting blade assembly includes a fixed blade holder 3 arranged horizontally, a movable blade holder 4 slidably connected to the fixed blade holder, and a cutting blade 7 connected to the movable blade holder 4;

[0049] The cyclic vibration unit 5 is configured to generate periodic vibration in the horizontal direction to drive the movable tool holder 4 to perform reciprocating motion in the horizontal direction.

[0050] Vertical drive mechanism 2 drives the cutting blade assembly to reciprocate along the height direction.

[0051] Specifically, refer to Figures 1 to 3 The work platform 1 is equipped with a horizontally arranged fixed tool holder 3, which serves to support and connect other components. The vertical drive mechanism 2 includes a main drive component 26 and guide seats 21 symmetrically arranged on the work platform 1. The guide seats 21 have vertically arranged guide holes, and a sliding guide rod 22 is slidably connected in the guide holes. The top of the sliding guide rod 22 is fixed to the fixed tool holder 3. The transmission component includes a connecting rod 23 hinged to the bottom of the sliding guide rod 22. The end of the connecting rod 23 away from the sliding guide rod 22 is hinged to the eccentric shaft 251 of the turntable 25. The turntable 25 is driven by the main drive component 26. The drive component 26 provides power for rotation; when the main drive component 26 drives the turntable 25 to rotate via the transmission belt 261, the circumferential motion of the eccentric shaft 251 is converted into the vertical reciprocating motion of the sliding guide rod 22 in the guide hole through the connecting rod 23, thereby driving the fixed knife holder 3 to move up and down. Protective blocks 12 are provided on both sides of the guide seat 21 to shield the rotating parts and prevent accidents. The heat-conducting material is placed on the cutting base plate 11. As a prior art, the cutting base plate 11 can be conveyed on the work platform 1 by the pushing action of a linear motor or an electric telescopic rod.

[0052] Reference Figure 2 An elastic reset member 27 is sleeved on the sliding guide rod 22. The elastic reset member 27 is placed between the fixed knife holder 3 and the slide block 51. The elastic reset member 27 is placed between the fixed knife holder 3 and the slide block 51 and sleeved on the sliding guide rod 22. It can eliminate the gap at the hinge, reduce the movement of the fixed knife holder 3, and improve the cutting accuracy. In addition, the elastic reset member 27 can buffer the impact force generated when the fixed knife holder 3 makes vertical reciprocating motion under the drive of the vertical drive mechanism 2, reduce device vibration and noise, and improve the stability of the cutting process and the service life of the equipment.

[0053] Reference Figure 3The bottom of the fixed tool holder 3 is provided with a linear guide rail 31 arranged along its length. The linear guide rail 31 has a dovetail structure and can be detachably connected to the fixed tool holder 3 by bolt fastening, or it can be integrated into the design. The dovetail structure of the linear guide rail 31 has good stability and can effectively prevent the moving tool holder 4 from derailing during sliding. Moreover, the detachable connection facilitates later maintenance and replacement.

[0054] Reference Figures 3 to 4 A movable tool holder 4 is slidably connected to the linear guide rail 31. The movable tool holder 4 can reciprocate in the horizontal direction under the action of the cyclic vibration unit 5. The cyclic vibration unit 5 includes a servo drive motor 56 and a slide 51 mounted on the fixed tool holder 3. The output end of the servo drive motor 56 is provided with an eccentric cam 55. A cyclic sliding pin 52 is slidably connected in the slide 51. The tail of the cyclic sliding pin 52 is fixed to the movable tool holder 4 by a spring fixing seat 53. The spring fixing seat 53 has an L-shaped structure. A spring 54 is provided between the cyclic sliding pin 52 and the slide 51 to drive the head of the cyclic sliding pin 52 to abut against the eccentric cam 55. Specifically, the head of the cyclic sliding pin 52 is provided with a positioning shoulder 521, which is sleeved on the cyclic sliding pin 52 and placed between the positioning shoulder 521 and the slide 51.

[0055] Reference Figure 4 When the servo drive motor 56 drives the eccentric cam 55 to rotate, the change in the contour of the eccentric cam 55 will push the circulating sliding pin 52 to slide in the slide block 51, thereby driving the moving tool holder 4 to perform horizontal reciprocating motion. The spring 54 ensures that the head of the circulating sliding pin 52 is always in close contact with the eccentric cam 55. The head of the circulating sliding pin 52 can also have various structural forms, such as an arc structure, which can reduce the friction with the eccentric cam 55 and make the movement smoother.

[0056] Reference Figure 5 The movable blade holder 4 is equipped with a clamping plate 6 for fixing the cutting blade 7. A height adjustment mechanism is provided between the clamping plate 6 and the movable blade holder 4. The height adjustment mechanism is used to adjust the distance between the cutting blade 7 and the work platform 1. Specifically, the movable blade holder 4 is equipped with a vertically arranged directional slide rail 41, which can be a T-shaped guide rail. The back of the clamping plate 6 is slidably connected to the directional slide rail 41, and the top of the clamping plate 6 is provided with a T-shaped groove 61 arranged along the length direction of the movable blade holder 4. The height adjustment mechanism includes an adjusting bolt 8 threadedly connected to the upper end of the fixed blade holder 3. The lower end of the adjusting bolt 8 is provided with a positioning part 81 that adapts to the T-shaped groove 61. The positioning part 81 can rotate in the T-shaped groove 61. By rotating the adjusting bolt 8, the position of the clamping plate 6 on the directional slide rail 41 can be changed, thereby realizing the adjustment of the height of the cutting blade 7 to accommodate heat-conducting materials of different thicknesses.

[0057] The implementation principle of this embodiment is as follows: The cutting device in this embodiment, through the coordinated work of the vertical drive mechanism 2 and the cyclic vibration unit 5, enables the cutting blade 7 to move along an elliptical trajectory, solving the problem that traditional cutting methods cannot meet the cutting needs of complex shapes. During operation, the heat-conducting material is placed on the work platform 1, and the height of the cutting blade 7 is adjusted according to the material thickness using the height adjustment mechanism. The main drive component 26 and the servo drive motor 56 are activated. The main drive component 26 drives the fixed blade holder 3 to move up and down, while the servo drive motor 56 drives the moving blade holder 4 to move left and right. Together, they cause the cutting blade 7 to form an elliptical running trajectory, precisely cutting the heat-conducting material. This structural design greatly improves the flexibility and accuracy of cutting, reduces material waste, and increases production efficiency. Compared with traditional cutting methods, it has significant advantages and represents a major improvement over existing heat-conducting material cutting technology.

[0058] Example 2

[0059] Reference Figure 6 The difference between this embodiment and Embodiment 1 is that the vertical drive mechanism 2 includes a main drive component 26 and guide seats 21 symmetrically arranged on the work platform 1. The guide seats 21 have vertically arranged guide holes, and a sliding guide rod 22 is slidably connected in the guide holes. The top of the sliding guide rod 22 is fixed on the fixed tool holder 3. The transmission component includes a crossbar 24 connected to the bottom of the two sliding guide rods 22. The crossbar 24 has a sliding groove 241. The output end of the main drive component 26 has a turntable 25. The turntable 25 has an eccentric shaft 251 adapted to the sliding groove 241. When the main drive component 26 drives the turntable 25 to rotate, the eccentric shaft 251 slides in the sliding groove 241, causing the crossbar 24 and the sliding guide rod 22 to perform vertical reciprocating motion, thereby realizing the up and down movement of the fixed tool holder 3.

[0060] Reference Figure 7 The head of the circulating sliding pin 52 is provided with a bullseye wheel 57. The bullseye wheel 57 has a low rolling friction coefficient, which can further reduce energy loss and improve transmission efficiency.

[0061] Reference Figure 8 The movable blade holder 4 is provided with a vertically arranged directional slide rail 41, and the back of the clamping plate 6 is slidably connected to the directional slide rail 41. The height adjustment mechanism includes an adjusting bolt 8 threadedly connected to the upper end of the fixed blade holder 3. The lower end of the adjusting bolt 8 abuts against the movable blade holder 4, and a spring 9 is provided between the movable blade holder 4 and the fixed blade holder 3 to drive the movable blade holder 4 to move upward. The spring 9 can eliminate the gap at the connection part, reduce the movement of the fixed blade holder 3, and improve the cutting accuracy.

[0062] The implementation principle of this embodiment is as follows: This embodiment, through the unique vertical drive mechanism 2 structure, can also realize the vertical reciprocating motion of the fixed blade holder 3. Combined with the cyclic vibration unit 5, it enables the cutting blade 7 to form an elliptical running trajectory. This structure is relatively simple, reduces components such as the connecting rod 23, reduces the probability of mechanical failure, and improves the reliability of the equipment. In actual operation, the main drive component 26 drives the turntable 25 to rotate, and the sliding of the eccentric shaft 251 in the slide groove 241 converts the circular motion into vertical linear motion, pushing the sliding guide rod 22 and the fixed blade holder 3 to move up and down. Combined with the horizontal motion of the cyclic vibration unit 5, it realizes the cutting of complex shapes of heat-conducting materials. While ensuring cutting accuracy, it improves the stability and durability of the equipment, providing a more reliable solution for cutting heat-conducting materials.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of this application.
