Detailed Description
Referring to fig. 1, a printing pen tube 1 is used for storing low-melting-point liquid metal, the low-melting-point metal is heated and melted in the printing pen tube 1, taking bismuth indium tin alloy with a melting point of 72 ℃ as an example, the most suitable printing pen tube 1 is 20g in weight and 23g after being filled with bismuth indium tin metal, and the printing pen tube 1 is formed by pressing multiple layers of silicon steel sheets. The pen slot 2 is used for supporting a printing pen tube, when the printing pen slot 2 is used for printing, the pen slot 2 falls, the printing pen tube 1 in the pen slot 1 freely falls, when the pen slot 2 is lifted, the printing pen tube 1 in a free vertical state is lifted at the same time, the pen slot 2 restrains the printing pen tube 1, and the printing pen tube 1 is always in a vertical state when being printed. The heating coil 3 and the buffer coil 4 have two working states, wherein the heating coil 3 is positioned inside the pen slot 2. The pen tip 5 is used for printing and writing low-melting-point liquid metal and forming a specific pattern, and the pen tip 5 can be replaced. The nib slot 6 is used for fixing the nib 5. The counterweight 6 is used for adjusting the whole counterweight of the printing pen tube 1 so as to adjust the printing pressure to be the most suitable, the counterweight 6 adopts a silicon wafer, the heat energy generated by electromagnetic induction influence can be avoided, the melting point of the silicon wafer is higher, and the heating temperature of most of low-melting-point liquid metal is adapted. The weight plate fixing nut 8 is used for fixing the weight plate 7. The feeding device 9 stores 0.5 multiplied by 0.5mm of spherical materials, and the spherical materials are formed by die-pressing after bismuth indium tin metal is melted. When the electromagnet 10 is electrified, the magnetic pole is attracted, and the pen groove 2 is controlled to lift or fall by the magnetic force. The magnetic pole 11 assists the electromagnet 10 to control the pen slot 2 to lift or fall. The connecting piece 12 connects the magnetic pole 11 and the pen slot 2. The pen holder temperature sensor 13 is used for detecting the temperature of the low-melting-point liquid metal in the printing pen holder 1 and transmitting the temperature data to the data receiver 15 through Bluetooth transmission. The nib temperature sensor 14 is used to detect the temperature of the low melting point liquid metal that is about to enter the nib 5 and transmit the temperature data to the data receiver 15 via bluetooth transmission. The data receiving part 15 is used for receiving the temperature data of the pen tube temperature sensor 13 and the pen point temperature sensor 14, then coupling and comparing the two temperature data, and sending real-time data to an upper computer when the data difference value is less than 1%, and recording and displaying the existing printing temperature; when the data difference is larger than 1%, the data are sent to the upper computer and a mark is output, the existing data are not displayed, and the temperature in the printing pen tube 1 is represented to be uneven.
The working process of the printing pen tube 1 in the embodiment of the invention is as follows:
before printing, two end points A and B of the heating coil 3 are communicated with an alternating circuit, an alternating magnetic field is generated in the coil, the alternating magnetic field can generate an eddy current in low-melting-point liquid metal in the printing pen tube 1, the low-melting-point metal is melted by heat generation through an eddy current effect, and an alternating electric field generated by the heating coil 3 and the buffer coil 4 generate electromagnetic induction to form a low-efficiency transformer. According to the principle of the voltage device, a part of the energy generated by the heating coil 3 forms an eddy current in the low-melting-point liquid metal to become heat energy, and the other part of the energy is transferred to the buffer coil 4 and is converted into heat energy by the buffer coil 4, so that the low-melting-point liquid metal coated by the buffer coil 4 generates the eddy current to become heat energy. In order to prevent most of the energy of the heating coil 3 from being transferred to the buffer coil 4, the distance between the heating coil 3 and the buffer coil 4 should be at least 3cm apart when the pen container 2 is in the lifted state. By adopting the technical scheme, when the printing pen tube 1 is in a heating state, the heating coil 3 and the buffer coil 4 can heat two metals coated by the heating coil at the same time, and the low-melting-point liquid metal has good heat conductivity, so that the low-melting-point liquid metal in the printing pen tube 1 is heated uniformly. In order to enhance the eddy current effect of the heating coil 3, the internal structure of the printing pen tube 1 can be adaptively made into an anti-convex structure, so that the eddy current heat generating effect in the printing pen tube 1 during heating is enhanced.
When printing, the electromagnet 10 is electrified to adsorb the magnetic pole 11, then the pen groove 2 is pressed downwards through the connecting piece 12, and the printing pen tube 1 falls freely in the pen groove 2. Meanwhile, two end points A and B of the heating coil 3 are communicated with a direct current power supply, the heating coil 3 can be used as an electromagnet, a magnetic field generated by the heating coil 3 passes through the buffer coil 4, and when the printing pen tube 1 falls freely, the buffer coil 4 and the heating coil 3 generate electromagnetic induction to generate mutual adsorption force due to the change of magnetic flux, so that the falling speed of the printing pen tube 1 is reduced. When the printing pen tube 1 falls on the base material, slight vibration in the vertical direction can be generated, and when the printing pen tube 1 vibrates upwards, electromagnetic induction is generated between the buffer coil 4 and the heating coil 3 again to generate mutually conflicting force, so that the upward vibration amplitude of the printing pen tube 1 is reduced. In order to enhance the buffering effect of the buffer coil 4, when the pen slot 2 is pressed down, the printing pen tube 1 falls freely on the base material, and the distance between the bottom of the heating coil 3 and the top of the buffer coil 4 is within 1 cm. By adopting the technical scheme, when the printing pen tube 1 is used for printing, the impact force of the impact on the base material can be effectively reduced, and the pressure during printing can be controlled by depending on the weight plate and the gravity of the printing pen tube 1.
After printing, the pen slot 2 is lifted, the printing pen tube 1 is erected, two end points A and B of the heating coil 3 are communicated with the alternating circuit again, and liquid metal is continuously heated. The data receiver 15 receives the pen barrel temperature and the pen point temperature for comparison, when the pen barrel temperature reaches a set value, if the deviation with the pen point temperature is large, the mode enters a constant temperature mode, namely, a heating state with low power is carried out, and when the pen barrel temperature and the pen point temperature are basically kept flat, printing can be started.
In the above working process, the distance control of the heating coil and the buffer coil is a relatively complicated process, and the factors affecting the thickness of the coil, the number of turns, the magnetic permeability of the low-melting-point liquid metal, and the like. When the distance between the heating coil and the buffer coil is too far, the buffer coil cannot achieve a good buffer effect; when the distance between the heating coil and the buffer coil is too close, the two coil systems become transformers with higher conversion efficiency, and most of the power of the heating coil is captured by the buffer coil. Therefore, when the magnetic permeability of the selected low-melting-point liquid metal is high, the distance between the heating coil and the buffer coil should be correspondingly increased, and when the magnetic permeability of the selected low-melting-point metal is low, the distance between the heating coil and the buffer coil should be correspondingly increased. According to the different types of the low-melting-point liquid metal selected during printing, the distance between the heating coil and the buffer coil is different, so that the structure of the printing pen tube 1 is also set in a corresponding adaptability mode.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
