The electric carving plate making is an important technology for manufacturing the plate roller, and a key part of the electric carving plate making equipment is an electric carving head which has decisive influence on printing quality and efficiency.
The traditional electric carving head is a device capable of outputting high-frequency reciprocating motion, namely, electric energy is converted into kinetic energy of mechanical motion, and the basic principle is that a cutter bar is driven by Lorentz force to drive a diamond cutter point on the electric carving head to cut into the specified depth of a copper layer on the surface of a roller. According to general rules, the working frequency of the system should be as far away from the first-order first resonant frequency as possible, if some fields require the working frequency to be at least 2 times of the first-order first resonant frequency, while the system where the existing electric engraving head is located generally works at a higher working frequency, such as 8000Hz or higher commonly used in the industry, and the first-order first resonant frequency of the existing mainstream engraving head is only 3000-4000 Hz, so that the difference between the working frequency of the system and the first-order first resonant frequency of the engraving head is not large, and thus the amplitude of the engraving head is too large, that is, the depth of cutting into a copper layer is too large, that is, the engraving head has an overshoot condition, and the convergence time of the engraving head is too long.

Please refer to fig. 1, which is a perspective view of an electric engraving needle assembly according to an embodiment of the present invention.
An electrosurgical needle assembly 10, comprising: an electro-engraving needle body 100 and a clamping assembly 200; the electric engraving needle body 100 is connected with the clamping assembly 200, the clamping assembly 200 includes a base 210 and a clamping member 220, the electric engraving needle body 100 is provided with a mounting hole 110, the mounting hole 110 is used for accommodating a torsion bar, the clamping member 220 is arranged on the base 210, the clamping member 220 is provided with an accommodating space 221, at least a part of the electric engraving needle body 100 is accommodated in the accommodating space 221, at least a part of the clamping member 220 close to the base 210 has a width smaller than that of the base 210, and the base 210 is used for being connected with a box body.
In this embodiment, when the torsion bar rotates, the rotation of the torsion bar drives the electric engraving needle body 100 to vibrate reciprocally, the clamping assembly 200 clamps the electric engraving needle body 100 through the clamping member 220, at least a part of the clamping member 220 close to the base 210 has a width smaller than that of the base 210, the clamping member 220 generates an acting force opposite to the vibration direction of the electric engraving needle body 100, so that the clamping member 220 reduces the vibration amplitude of the electric engraving needle body 100, that is, the overall rigidity of the electric engraving needle assembly is increased, the working frequency of the electric engraving needle assembly is far greater than the first resonance frequency of the electric engraving needle body 100, the overshoot probability of the electric engraving needle body 100 is reduced, and the convergence time of the electric engraving needle body 100 is reduced.
Moreover, the first resonant frequency of the electric engraving needle body is 3000-4000 Hz, and the working frequency of the electric engraving needle assembly adopting the structure is far higher than 8000Hz, so that the working frequency of the electric engraving needle assembly is two times or more than the first resonant frequency of the electric engraving needle body. The design is beneficial to avoiding overshoot of the electric carving needle body and reducing the convergence time of the electric carving needle body.
In one embodiment, referring to fig. 2, one end of the clamping member 220 close to the base 210 has an arc-shaped portion 230, and at least a part of the width of the arc-shaped portion 230 is smaller than that of the base 210. In this embodiment, the arc-shaped part 230 is located on the base 210, the arc-shaped part 230 is connected to the base 210, and the arc-shaped part 230 vibrates reciprocally on the base 210, that is, when the body 100 of the electric carving needle vibrates, the arc-shaped part 230 vibrates along with the body of the electric carving needle. Since the width of a part of the arc part 230 is smaller than the width of the base 210, so that the arc part 230 has elasticity for movement, the clamping member 220 is subjected to a certain elastic restoring force in the vibration process by the elastic force of the arc part 230, that is, the arc part 230 generates a damping effect on the electric engraving needle body, for example, when the torsion bar rotates, the electric engraving needle body vibrates, so that the clamping member 220 follows the electric engraving needle body to reciprocate, the arc part 230 provides a damping force when the clamping member 220 deviates from the position in the stable state, that is, the arc part 230 generates a force opposite to the movement trend of the clamping member 220, so that the clamping member 220 moves towards the position in the stable state, and the vibration amplitude of the electric engraving needle body is reduced, the overall rigidity of the electric carving needle body is improved. Moreover, under the condition of constant energy, the vibration frequency of the electric carving needle body in unit time is increased, namely the working frequency of the electric carving component is increased, namely the working frequency of the electric carving needle component is two times or more than the first resonance frequency of the electric carving needle body, so that the probability of overshoot of the electric carving needle body is reduced, and the convergence time of the electric carving needle body is shortened.
In one embodiment, referring to fig. 2, the width of the middle portion of the arc portion 230 is smaller than the width of the end portion of the arc portion 230. In this embodiment, the width of the arc portion 230 varies, wherein the width of the middle portion of the arc portion 230 is different from the widths of the other positions, and the width of the middle portion of the arc portion 230 is different from the widths of the clamping member 220 and the base 210, i.e., the width of the middle portion of the arc portion 230 is smaller than at least one of the width of the clamping member 220 and the width of the base 210, for example, the width of the middle portion of the arc portion 230 is smaller than the width of the clamping member 220; for another example, the width of the middle portion of the arc portion 230 is smaller than the width of the base 210; for another example, the width of the middle portion of the arc portion 230 is smaller than the width of the clamping member 220 and the base 210. In this way, the width of the middle of the arc-shaped part 230 is smaller than that of the end of the arc-shaped part 230, so that the end of the arc-shaped part 230 can vibrate, even if the arc-shaped part 230 deforms, so that the end of the arc-shaped part 230 can generate damping force, i.e. the end of the arc-shaped part 230 generates an acting force opposite to the movement trend of the clamping member 220, so that the clamping member 220 moves towards the position in the stable state, the vibration amplitude of the electric engraving needle body is reduced, and the overall rigidity of the electric engraving needle body is improved. Moreover, under the condition of constant energy, the vibration frequency of the electric carving needle body in unit time is increased, namely the working frequency of the electric carving component is increased, namely the working frequency of the electric carving needle component is two times or more than the first resonance frequency of the electric carving needle body, so that the probability of overshoot of the electric carving needle body is reduced, and the convergence time of the electric carving needle body is shortened.
In one embodiment, referring to fig. 2, the width of the arc portion 230 near the end of the base 210 is equal to the width of the base 210. In this embodiment, the arc part 230 has an arc structure, that is, the widths of the portions of the arc part 230 are not equal, that is, the width of a portion of the arc part 230 is different from the widths of other portions. When the electric engraving needle assembly works, the electric engraving needle body performs reciprocating vibration motion on a rotation action line of the torsion bar, the arc-shaped part 230 is vibrated by the vibration of the electric engraving needle body, that is, the arc-shaped structure of the arc-shaped part 230 is deformed, so that the arc-shaped part 230 generates a damping effect on the electric engraving needle body, and the arc-shaped part 230 has a tendency of recovering to a stable state, that is, the restoring force of the arc-shaped part 230 generated by the damping effect is opposite to the vibration direction of the arc-shaped part 230. In this way, when the width of the end of the arc part 230 close to the base 210 is equal to the width of the base 210, the end of the arc part 230 close to the base 210 keeps the same with the vibration of the base 210, that is, the end of the arc part 230 close to the base 210 has the same motion state, and since the base 210 is fixed on a box, the base 210 does not deflect or vibrate when the electric engraving needle assembly works, so that the base 210 is stably arranged on the box, and further, the end of the arc part 230 close to the base 210 does not vibrate, thereby increasing the rigidity of the part of the arc part 230 close to the base 210 and increasing the vibration frequency of the part of the arc part 230 close to the base 210. Under the condition of certain energy, the vibration frequency of the electric engraving needle body in unit time is increased, namely the working frequency of the electric engraving assembly is increased, namely the working frequency of the electric engraving needle assembly is two times or more than the first resonance frequency of the electric engraving needle body, so that the overshoot probability of the electric engraving needle body is reduced, and the convergence time of the electric engraving needle body is shortened.
In one embodiment, the arc-shaped part is integrally formed with the base, so that a connection gap between the arc-shaped part and the base is reduced, the mechanical strength between the arc-shaped part and the base is improved, the rigidity between the arc-shaped part and the base is improved, the vibration frequency of the arc-shaped part is increased, the vibration frequency of the electric carving needle body in unit time is increased under the condition of certain energy, namely the working frequency of the electric carving assembly is increased, the overshoot probability of the electric carving needle body is reduced, and the convergence time of the electric carving needle body is reduced.
In one embodiment, referring to fig. 2, the width of the arc portion 230 near one end of the clamping member 220 is equal to the width of the clamping member 220. In this embodiment, the arc part 230 has an arc structure, that is, the widths of the portions of the arc part 230 are not equal, that is, the width of a portion of the arc part 230 is different from the widths of other portions. When the electric engraving needle assembly works, the electric engraving needle body performs reciprocating vibration motion on a rotation action line of the torsion bar, the arc-shaped part 230 is vibrated by the vibration of the electric engraving needle body, that is, the arc-shaped structure of the arc-shaped part 230 is deformed, so that the arc-shaped part 230 generates a damping effect on the electric engraving needle body, and the arc-shaped part 230 has a tendency of recovering to a stable state, that is, the restoring force of the arc-shaped part 230 generated by the damping effect is opposite to the vibration direction of the arc-shaped part 230. Thus, when the width of the arc part 230 near the end of the clamping member 220 is equal to the width of the clamping member 220, the end of the arc part 230 near the clamping member 220 keeps consistent with the vibration of the base 210, i.e. the end of the arc part 230 near the clamping member 220 has the same motion state. Due to the fact that the arc-shaped part 230 deforms to generate a damping force opposite to the movement direction of the arc-shaped part, the vibration amplitude of one end, close to the clamping piece 220, of the arc-shaped part 230 is reduced, under the condition that energy is constant, the vibration frequency of one end, close to the clamping piece 220, of the arc-shaped part 230 is increased, the vibration frequency of the electric carving needle body in unit time is increased, namely the working frequency of the electric carving assembly is increased, namely the working frequency of the electric carving needle assembly is two times or more than the first resonance frequency of the electric carving needle body, the probability of overshoot of the electric carving needle body is reduced, and meanwhile the convergence time of the electric carving needle body is also reduced.
In one embodiment, the arc-shaped part is a part of the clamping member, that is, the arc-shaped part and the clamping member are integrally formed, so that a connection gap between the arc-shaped part and the clamping member is reduced, the mechanical strength between the arc-shaped part and the clamping member is improved, the rigidity between the arc-shaped part and the clamping member is improved, the vibration frequency of the arc-shaped part is increased, the vibration frequency of the electric engraving needle body in unit time is increased under a certain energy condition, that is, the working frequency of the electric engraving assembly is increased, the probability of overshoot of the electric engraving needle body is reduced, and the convergence time of the electric engraving needle body is shortened.
In one embodiment, referring to fig. 2, the arc portion 230 has two arc slots 231, two sides of the arc portion 230 are respectively provided with one arc slot 231, and the openings of the two arc slots 231 are opposite to each other. In this embodiment, the arc portion 230 is a rectangular body, and the arc slots 231 are opened at two sides of the arc portion 230, that is, the arc portion 230 is a rectangular body having grooves at two sides. The formation of the two arc-shaped slots 231 reduces the width of the partial area of the arc-shaped part 230, the opening directions of the two arc-shaped slots 231 face to two opposite directions, and the opening directions of the two arc-shaped slots 231 are opposite to each other, i.e. the opening direction of one arc-shaped slot 231 is parallel to and does not intersect with the opening direction of the other arc-shaped slot 231. The two arc-shaped grooves 231 are oppositely arranged at two sides of the arc-shaped part 230, the distance between the bottoms of the two arc-shaped grooves 231 is the minimum width of the arc-shaped part 230, so that the arc-shaped part 230 is deformed conveniently, the damping effect generated by the arc-shaped part 230 is enhanced, the vibration amplitude of the arc-shaped part 230 is reduced, the rigidity of the arc-shaped part 230 is increased, the vibration frequency of the electric engraving needle body in unit time is increased, namely the working frequency of the electric engraving assembly is increased, namely the working frequency of the electric engraving needle assembly is two times or more than the first resonance frequency of the electric engraving needle body, therefore, the probability of overshoot of the electric engraving needle body is reduced, and the convergence time of the electric engraving needle body is reduced.
In one embodiment, referring to fig. 2, the two arc-shaped slots 231 are located in the middle of the arc-shaped portion 230, that is, the center of the arc-shaped slot 231 and the center of the height of the arc-shaped portion 230 are located on the same horizontal line, and a line connecting the center of the arc-shaped slot 231 and the center of the height of the arc-shaped portion 230 is parallel to the base 210.

Thus, when the electric engraving needle assembly works, the electric engraving needle body vibrates back and forth under the rotation of the torsion bar, namely the electric engraving needle body vibrates along the direction parallel to the base 210, namely the electric engraving needle body has a motion trend along the direction parallel to the base 210, and the two clamping parts 222 block the vibration of the electric engraving needle body, so that the motion trend of the electric engraving needle body is weakened, the motion amplitude of the electric engraving needle body is reduced, the mechanical strength between the electric engraving needle body and the clamping parts 220 is improved, and the overall rigidity of the electric engraving needle assembly is further improved. Under the condition of certain energy, the motion amplitude of the electric engraving needle body is reduced, so that the vibration frequency of the electric engraving needle body is increased, namely the vibration frequency of the electric engraving needle body is increased, the vibration frequency of the electric engraving needle body in unit time is increased, namely the working frequency of the electric engraving assembly is increased, namely the working frequency of the electric engraving needle assembly is two times or more than the first resonance frequency of the electric engraving needle body, the probability of overshoot of the electric engraving needle body is reduced, and meanwhile, the convergence time of the electric engraving needle body is also reduced.
