Description

Technical Field

[0001] The utility model relates to the technical field of surface wire drawing, in particular to a surface wire drawing device for improving the bonding force of steel sheets. Background Art

[0002] Steel sheet reinforcement plays a very important role in the application of FPC products. In FPC products, steel sheet reinforcement has a relatively high requirement for the heat dissipation function of high-end products. The grounding resistance conductivity of steel sheet reinforcement, the bonding strength between steel sheet and product, and the bonding strength between steel sheet and conductive adhesive directly affect the functional problems of the product. Only with good steel sheet grounding resistance conductivity can the product signal output be well connected; only with good steel sheet reinforcement bonding can the product get good heat dissipation during use, and at the same time, it can ensure that the steel sheet reinforcement bonding is very good without stratification, cracking, and affecting the smoothness of the product. Output stable work.

[0003] The existing steel sheet surface treatment process is to assemble the steel sheet to the product after lamination and pressing. When the steel sheet is put into use at the customer end, the steel sheet and the conductive adhesive will be delaminated due to the bonding problem when the steel sheet is exposed to high temperature, which will cause the surface of the product to bulge, making the entire product flat and unable to work properly. Severe delamination will cause the circuit in the circuit board product to crack and cause poor functionality. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0046] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0047] Sound waves are longitudinal waves that can be felt by the human ear, and their frequency is in the range of 16 to 16,000 Hz. When the frequency exceeds 16,000 Hz, it is called ultrasound. Ultrasound waves, like sound waves, can propagate in media such as gas, liquid and solid. Due to the high frequency, short wavelength and high energy of ultrasound waves, reflection, refraction, resonance and loss are significant during propagation. Ultrasound waves mainly have the following properties:

[0048] (1) Ultrasonic waves can transmit very strong energy. The main function of ultrasonic waves is to exert pressure (sound pressure) on obstacles in the direction of their propagation. Therefore, the magnitude of this pressure can be used to represent the intensity of ultrasonic waves. The stronger the propagating wave energy, the greater the pressure. When ultrasonic waves are propagated in liquids or solids, the density of the medium and the vibration frequency are many times higher than when sound waves are propagated in air. Therefore, for the same amplitude, the intensity, power, and energy density of ultrasonic waves in liquids and solids are tens of millions of times higher than those in air.

[0049] (2) When ultrasonic waves propagate through a liquid medium, they will compress the liquid particles to vibrate at a very high frequency, continuously forming compression and rarefaction areas in the liquid medium. Since the liquid is basically incompressible, hydraulic shock and cavitation phenomena with alternating positive and negative pressures will occur. This process takes a very short time, and the closing pressure of the liquid cavity can reach tens of atmospheres, and can produce huge water pressure shocks. This alternating pulse pressure will damage the surface of adjacent parts, causing the solid matter to disperse and break, etc.

[0050] (3) When ultrasonic waves pass through different media, a sudden change in wave velocity can occur at the interface, resulting in wave reflection and refraction. The amount of energy reflected is determined by the wave impedance of the two media (the product of density and wave velocity is called wave impedance). The greater the difference in the wave impedance of the two media, the higher the energy reflectivity when the ultrasonic wave passes through the interface. When ultrasonic waves transition from liquid or solid to air (or vice versa), the reflectivity is close to 100%. In addition, since air is compressible, it hinders the propagation of ultrasonic waves. In order to improve the transmission conditions of ultrasonic waves in adjacent media, engine oil and vaseline are often added between the connecting surfaces of the ultrasonic vibration system as transmission media.

[0051] (4) Ultrasonic waves will produce wave interference and resonance under certain conditions. When ultrasonic waves propagate from one end of the elastic rod to the other, reflection of the waves will occur at the end of the rod. In a finite elastic body, there are actually two waves with the same period, amplitude and opposite propagation directions. When these two identical waves meet from opposite directions, wave interference will occur. When the length of the rod conforms to a certain rule, some points on the rod remain unchanged during the wave fluctuation, and their amplitude is zero (wave nodes), while other points have the largest amplitude, which is twice the original amplitude (wave antinodes). Of course, to apply ultrasonic waves to the processing field, its large amplitude resonance characteristics must be fully utilized.

[0052] Therefore, ultrasonic machining can utilize the end face of the workpiece for ultrasonic frequency vibration, and the steel sheet can be processed by abrasive suspension. During processing, liquid and suspension are added between the containers of the machine tool 1004, and the workpiece is gently pressed on the workpiece. The ultrasonic transducer 1002 generates ultrasonic frequency vibrations above 16000 Hz, and the amplitude is amplified to about 0.05-0.1 mm by means of a horn, driving the end face of the workpiece to perform ultrasonic vibrations, forcing the abrasive particles suspended in the working fluid to continuously impact and polish the processed surface at a high speed and acceleration, crushing the material on the processed surface into very fine particles, and knocking it off the workpiece. Although the material knocked off each time is small, there is still a certain processing speed due to the maximum number of knocks per second. The circulating suspension takes away the fallen particles and continuously renews the abrasive. At the same time, the high frequency, positive and negative alternating hydraulic shock waves and "cavitation" generated by the ultrasonic vibration of the workpiece surface cause the working fluid to drill into the micro cracks of the processed material, further intensifying the mechanical crushing effect. As the processing continues, the shape of the workpiece is eventually "copied" on the workpiece to achieve the required size.

[0053] The following will be combined Figure 1 A clear and complete description is given of the surface wire drawing device for improving the bonding force of steel sheets according to the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments.

[0054] According to the surface wire drawing device for improving the bonding force of a steel sheet according to an embodiment of the utility model, the surface wire drawing device comprises:

[0055] The ultrasonic generator 1001 is used to convert industrial frequency alternating current into an adjustable ultrasonic frequency.

[0056] The ultrasonic transducer 1002 is connected to the ultrasonic generator 1001 and is used to convert high-frequency electrical energy into ultrasonic waves; the high-frequency electrical energy is obtained by adjusting the ultrasonic frequency.

[0057] The amplitude amplification rod 1003 is connected to the ultrasonic transducer 1002 and is used to amplify the amplitude deformation of the ultrasonic transducer 1002 to obtain amplified ultrasonic waves.

[0058] The machine tool 1004 is disposed at the lower part of the amplitude amplification rod 1003 and is used to place the workpiece to be processed by the amplified ultrasonic wave.

[0059] The piezoelectric transducer 1005 is connected to the machine tool 1004 and is used to convert the impact force on the workpiece into a charge signal.

[0060] The charge amplifier 1006 is connected to the piezoelectric transducer 1005 and is used to receive the charge signal and convert the charge signal into a voltage signal that can be received by the oscilloscope 1007 .

[0061] The oscilloscope 1007 is connected to the charge amplifier 1006 and is used to process the voltage signal to obtain an oscilloscope result and display the oscilloscope result.

[0062] The feed pressure regulator 1008 is connected to the oscilloscope 1007 and the machine tool 1004, and is used to adjust the feed pressure of the workpiece according to the oscilloscope result.

[0063] First, the industrial frequency alternating current is converted into an adjustable ultrasonic frequency through an ultrasonic generator, which can adjust the ultrasonic frequency and has high flexibility; then, the high-frequency electrical energy is converted into ultrasonic waves through the ultrasonic transducer 1002. Since the high-frequency electrical energy is obtained by adjusting the ultrasonic frequency, the range of the ultrasonic wave is also highly flexible and can adapt to more task scenarios; then, the amplitude deformation of the ultrasonic transducer 1002 is enlarged by the amplitude expansion rod 1003 to obtain the amplified ultrasonic wave, thereby achieving the purpose of reducing energy consumption and saving costs; then, the workpiece is placed through the machine tool 1004, which can fix the relative position of the amplified ultrasonic wave and the workpiece, facilitating the processing of the workpiece; then, the piezoelectric transducer 1005 is used to monitor , obtain the impact force on the workpiece and convert it into a charge signal, which can obtain the charge signal representing the impact force on the workpiece in real time; then the charge amplifier 1006 converts the charge signal into a voltage signal that can be received by the oscilloscope 1007, providing good input data for the subsequent oscilloscope 1007 to ensure the correctness of the oscilloscope result; then the oscilloscope 1007 processes the voltage signal to obtain the oscilloscope result and displays the oscilloscope result, which can monitor the voltage signal intuitively, and also monitor the surface wire drawing treatment; finally, the feed pressure of the workpiece is adjusted according to the oscilloscope result through the feed pressure regulator 1008, so as to reasonably control the roughness of the steel sheet surface and improve the effect of the surface wire drawing treatment.

[0064] In some embodiments of the utility model, the ultrasonic generator is composed of a power supply, an oscillation stage, a voltage amplifier stage and a power amplifier stage connected in sequence; the oscillation stage is obtained by forming an inductive feedback oscillation circuit with an electron tube or a triode, and the oscillation frequency of the inductive feedback oscillation circuit is adjusted by the capacitance of the electron tube or the triode; the voltage amplifier stage is used to amplify the output of the oscillation stage; and the power amplifier stage is used to process the output of the voltage amplifier stage through multi-tube parallel push-pull.

[0065] It should be noted that the ultrasonic generator is also called an ultrasonic wave or ultrasonic frequency generator. Its function is to convert industrial frequency alternating current into ultrasonic frequency oscillation with a certain power output to provide reciprocating vibration of the workpiece end face and remove the energy of the processed material. Therefore, preferably, the oscillation stage is connected by an electron tube or a triode to form an inductive feedback oscillation circuit. The oscillation frequency can be changed by adjusting the capacitance, that is, the output ultrasonic frequency can be adjusted; the output of the oscillation stage is coupled to the voltage amplifier stage for amplification, and then transmitted to the final power amplifier tube by a transformer inverting; the power amplifier tube sometimes uses multiple tubes in parallel for push-pull output, which is transmitted to the ultrasonic transducer 1002 through the output transformer.

[0066] The ultrasonic generator is composed of a power supply, an oscillation stage, a voltage amplifier stage and a power amplifier stage connected in sequence. It has a simple structure, reliable operation, high efficiency, and is easy to operate and maintain. At the same time, the oscillation frequency can be adjusted so that the output power has a large continuous adjustable range to adapt to the processing of different workpieces.

[0067] In some embodiments of the present invention, the transducer is a piezoelectric effect ultrasonic transducer.

[0068] It should be noted that when quartz crystal, barium titanate and lead zirconate are mechanically compressed or stretched, a certain charge will be generated on the interface between the two opposite surfaces, forming a certain potential; conversely, a certain voltage will be applied to the two opposite surfaces, which will produce a certain mechanical deformation. This phenomenon is called the piezoelectric effect. If an alternating voltage of more than 16,000 Hz is applied to both sides, the material will produce high-frequency expansion and contraction deformation, causing the surrounding medium to vibrate ultrasonically, which is called a piezoelectric effect ultrasonic transducer.

[0069] Preferably, in order to obtain the maximum ultrasonic wave intensity, the crystal should be in a resonant state, so the thickness of the crystal sheet should be an integer multiple of half the wavelength of the ultrasonic wave.

[0070] The piezoelectric effect ultrasonic transducer has a simple structure and reliable operation, and can reduce production costs to a certain extent.

[0071] In some embodiments of the present invention, the piezoelectric effect ultrasonic transducer uses lead zirconate ferrite as a conductive material.

[0072] It should be noted that the expansion and contraction of quartz crystal is too small, and a voltage of 3000V can produce a deformation of less than 0.01um. The piezoelectric effect of barium titanate is 20 to 30 times greater than that of quartz crystal, but its efficiency and mechanical strength are not as good as those of quartz crystal. Lead zirconate titanate has the advantages of both.

[0073] Selecting lead zirconate ferrite as the conductive material of the piezoelectric effect ultrasonic transducer can provide good expansion and contraction and mechanical strength, and can improve the working efficiency of the piezoelectric effect ultrasonic transducer.

[0074] In some embodiments of the present invention, the amplitude amplification rod 1003 is a stepped amplitude rod.

[0075] It should be noted that the types of amplitude amplifiers of the amplitude amplification rod 1003 include conical, exponential and stepped shapes. The conical amplitude amplifier is easy to manufacture; the exponential amplitude amplifier has an amplitude amplification ratio of 10 to 20 times, works stably but is difficult to manufacture; the stepped amplitude amplifier has an amplitude amplification ratio of more than 20 times and is easy to manufacture.

[0076] Preferably, a transition arc is added at the step of the stepped horn. The step of the stepped horn is prone to fatigue fracture due to stress concentration. Adding the transition arc can reduce the amplitude attenuation of the stepped horn when subjected to load resistance and prevent fatigue fracture at the step.

[0077] Preferably, the length is equal to half the wavelength of the ultrasonic vibration or an integral multiple thereof, so that a larger amplitude can be obtained.

[0078] The stepped horn is easy to manufacture and has an excellent amplitude amplification effect, which can save a lot of production costs and improve production efficiency.

[0079] Reference Figure 2 In some embodiments of the present utility model, the surface drawing device further includes:

[0080] The cooling device 101 covers the surface of the ultrasonic transducer 1002 and is used to cool the ultrasonic transducer 1002 .

[0081] The cooling device 101 can prevent the working temperature of the ultrasonic transducer 1002 from being too high, which may cause the ultrasonic transducer 1002 to be overloaded and cause serious failures. At the same time, it can also increase the working power upper limit of the ultrasonic transducer 1002 and improve working efficiency.

[0082] In some embodiments of the present invention, the abrasive working fluid of the machine tool 1004 is composed of water and boron carbide.

[0083] It should be noted that water is the most commonly used working fluid with the best effect. In order to improve the surface quality, kerosene or engine oil is sometimes used as the working fluid. Abrasive grains generally use silicon carbide and aluminum oxide, but boron carbide is used when processing hard alloys, and diamond powder is used when processing diamonds. The size of the abrasive grains is selected according to the processing productivity and precision requirements. Larger grains have higher productivity, but the processing precision and surface roughness are poorer.

[0084] Since the abrasive working fluid is used for steel sheets, water and boron carbide are selected to form the abrasive working fluid, which can not only reduce production costs but also cope with high-hardness steel sheets. The particle size of the abrasive particles can be selected according to the processing productivity and precision requirements, and no specific restrictions are made here.

[0085] In some embodiments of the present invention, the charge amplifier 1006 includes a quasi-static amplifier, and the quasi-static amplifier is used to receive a charge signal.

[0086] It should be noted that the quasi-static charge amplifier refers to a charge amplifier with quasi-static characteristics. The quasi-static charge amplifier has the advantages of small drift and good low-frequency characteristics.

[0087] In some embodiments of the utility model, the feed pressure regulator is composed of an oscilloscope result monitor and a finite element model connected in sequence. The oscilloscope result monitor is used to monitor the oscilloscope result according to a preset threshold value, and the finite element model is used to perform optimization simulation based on the oscilloscope result to obtain a simulated feed pressure regulation result.

[0088] It should be noted that the preset threshold is set according to the effect of the surface wire drawing treatment, and the effect of the surface wire drawing treatment can be monitored by real-time monitoring of the oscilloscope results. The parameter simulation and model processing of the finite element model can be set and trained in advance, or the parameters of each component can be obtained in real time through sensors, which are not specifically limited here. There should be a suitable feed pressure on the workpiece during processing. If the pressure is small, the gap between the workpiece processing surface increases, the impact force and impact depth of the abrasive on the workpiece are reduced, and the processing speed decreases; if the pressure is too large, the gap between the tool end and the workpiece processing surface becomes smaller, the abrasive and the working fluid cannot be updated smoothly, and the acceleration also slows down. For example, when a circular solid tool is used to process holes on glass, when the processing area is in the range of 5 to 13 mm, the optimal static pressure is about 4000 kPa; when the processing area is 20 mm, the optimal static pressure is about 2000 to 3000 kPa. Therefore, adjusting the feed pressure can adjust the effect and working speed of the surface wire drawing treatment.

[0089] The oscilloscope result monitor and the finite element model can avoid the problem of poor surface drawing treatment effect, and real-time monitoring can be performed. Once the oscilloscope result is not within the preset threshold, the simulated feed pressure adjustment result can be immediately calculated through the finite element model. The feed pressure can be adjusted immediately based on the simulated feed pressure adjustment result to improve the surface drawing treatment effect.

[0091] The adsorption device 102 is connected to the machine tool 1004 and is used to clean the scrap metal in the abrasive working fluid.

[0092] By cleaning the waste metal in the abrasive working fluid through the adsorption device 102, the working state of the abrasive working fluid can be maintained, and the effect of the surface wire drawing treatment can be maintained.
