Description

Technical Field

[0001] The invention belongs to the technical field of aluminum foil processing, and in particular relates to a method for improving the bending performance of aluminum foil by utilizing electronic light waves. Background Art

[0002] In the application of aluminum foil, it is often necessary to bend it to meet the design requirements of different electronic components. The aluminum foil bending method in the prior art mainly relies on mechanical force, which has problems such as limited bending angle and easy cracking.

[0003] For example, a Chinese invention patent application discloses a bending and buckling forming process for aluminum foil products [application number: 201710437487.3]. The invention application includes that after the aluminum foil product is punched and formed in a forming machine, the edge of the aluminum foil product needs to be bent and buckled to form, 1) the aluminum foil product is clamped by a floating upper die and a floating lower die, the bending insert on the upper die moves downward to bend the edge of the aluminum foil product, the upper die drives the bending insert to return, and the floating lower die shrinks inward, so that there is a buckling distance between the floating lower die and the bending position of the edge; 2) the buckling insert on the lower die presses the bending position of the edge of the aluminum foil product inward, and the bending position of the edge buckles along the designed surface of the buckling insert Composite type; the gap between the floating upper die and the bending insert is designed to be less than or equal to 0.1mm; the peripheral contour of the floating upper die is a sharp angle; the outer side of the peripheral contour of the floating lower die is polished to a mirror surface; the gap between the floating lower die and the bending insert in the first step is the edge thickness of the aluminum foil product; the profile designed by the snap-fit ​​insert is a step at the extruded angle, the lower end of the step is designed to be a spoon shape, the upper side of the step is a plane, and the profile is polished to a mirror surface; the gap between the floating lower die and the snap-fit ​​insert is less than or equal to 1mm; the gap between the plane of the upper side of the step of the snap-fit ​​insert and the floating upper die is less than or equal to 0.1mm.

[0004] Although this invention application has the advantages of improving the appearance of the product and preventing the aluminum foil from overflowing from the front of the product during pressing, it still adopts the traditional mechanical bending method, so there are still problems such as limited bending angle and easy cracking mentioned above. Summary of the invention

[0005] The purpose of the present invention is to provide a method for improving the bending performance of aluminum foil by using electronic light waves in order to solve the above problems.

[0006] A method for preparing a high-porosity anode material comprises the following steps:

[0007] A method for improving the bending performance of aluminum foil by using electronic light waves, comprising the following steps:

[0008] Step 1: Place the aluminum foil to be processed on the conveyor and fix its position using a positioning device;

[0009] Step 2: Start the electron light wave generating system and irradiate the aluminum foil according to the preset parameters. Under the action of the electron light wave, the internal structure of the aluminum foil is changed to improve its flexibility and plasticity.

[0010] Step 3: After irradiation, the finished aluminum foil is obtained, and the aluminum foil is transferred to the storage area using a conveyor.

[0011] The common methods of generating electron light waves are:

[0012] 1. Use light emitting diodes (LEDs): through the recombination of electrons and holes in semiconductor materials, electrical energy is converted into light energy to generate light waves. For example, the above-mentioned Liupeng Electronics white light mixed light composite light wavelength 400nm-500nm collimated parallel LED light source white light emitter uses LED to generate light waves in a specific wavelength range.

[0013] 2. Use laser diode: Based on the principle of stimulated radiation, in the PN junction of semiconductor materials, the particle number inversion distribution is achieved by injecting current, thereby generating laser. The light waves generated have the characteristics of high directivity, high monochromaticity and high brightness.

[0014] 3. With the help of plasma light source: by applying high voltage or high-frequency electric field to the gas, the gas is ionized to form plasma. When the electrons in the plasma transition back to the ground state, they radiate light waves.

[0015] 4. Use synchrotron radiation sources: By accelerating electrons to make circular motion in a magnetic field, the electrons will radiate electromagnetic waves, including light waves, along the tangent direction when changing the direction of motion. This light source can produce light in a wide wavelength range, from infrared to X-rays.

[0016] In the present invention, the electronic light wave generating system used is FIRECOMMS Falcon, which has a fiber optic transmitter model FT50MHNR, which integrates a highly reliable resonant cavity light emitting diode (RCLED) and a precision driver IC, has an emission wavelength of 650nm, a transmission rate of DC-50MBd, and can be powered by a 5V or 3.3V±10% power supply. There is also a FT10MHNR model, which is fully compatible with the HFBR-1528 and 1529 series.

[0017] In the above-mentioned method of improving the bending performance of aluminum foil by using electronic light waves, the maximum bending angle of the finished aluminum foil is greater than 150 degrees.

[0018] In the above-mentioned method of improving the bending performance of aluminum foil by using electronic light waves, the number of bending operations of the finished aluminum foil is more than 200 times.

[0019] In the above-mentioned method of improving the bending performance of aluminum foil by using electron light waves, the crack generation rate of the finished aluminum foil during the bending process is less than 1%.

[0020] In the above-mentioned method of improving the bending performance of aluminum foil by using electron light waves, the wavelength of the electron light waves in step 2 is 355nm-10.64μm, and the frequency is 2.82×10 13 Hz-8.45×10 14 Hz.

[0021] In the above-mentioned method of improving the bending performance of aluminum foil by using electron light waves, the wavelength of the electron light waves in step 2 is 650nm and the frequency is 4.61×10 14 Hz.

[0022] In the above-mentioned method of improving the bending performance of aluminum foil by using electron light waves, the power of the electron light wave generating system in step 2 is 5W-200W.

[0023] For thinner aluminum foil sheets, such as those with a thickness of several microns to tens of microns, the laser intensity can be several watts to tens of watts; for thicker aluminum foil sheets or aluminum foil layers in multi-layer composite materials, higher intensity is required, such as 50W-200W.

[0024] In the above-mentioned method of improving the bending performance of aluminum foil by using electron light waves, the irradiation time of the electron light waves in step 2 is 10ns-3min.

[0025] In the above-mentioned method of improving the bending performance of aluminum foil by using electron light waves, the irradiation time of the electron light waves in step 2 is 15 seconds.

[0026] Extremely short-time irradiation is generally suitable for high-precision processing, such as micro-pattern engraving or fine cutting of aluminum foil. The required irradiation time is extremely short, usually at the nanosecond level, to avoid excessive heat-affected areas and ensure processing accuracy.

[0027] Short-time irradiation is generally suitable for general aluminum foil stripping operations, such as removing aluminum foil from electronic component pins or circuit boards. The irradiation time is approximately in milliseconds, which can quickly complete the stripping and reduce damage to the base material.

[0028] The present invention mainly adopts a continuous irradiation method, which is generally suitable for surface treatment or modification of large-area aluminum foil sheets, and the irradiation time ranges from a few seconds to a few minutes.

[0029] Compared with the prior art, the advantages of the present invention are:

[0030] The present invention provides a new technology for increasing the bending performance of aluminum foil by utilizing electron light waves. By bombarding the aluminum foil with electron light waves of a specific frequency and intensity, the surface of the aluminum foil becomes smoother and the thickness tends to be uniform. At the same time, its internal crystal structure and molecular arrangement are changed, thereby improving the flexibility and plasticity of the aluminum foil and significantly enhancing its bending performance.
