DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] The present invention provides a tungsten wire processing device, the structure of which is as follows Figure 1 - Figure 8 As shown, it includes a wire unwinding device 1, an electrolysis device 2, a cleaning device 3, a wire collecting device 4, a drying device 5 and an intelligent wire diameter controller which are arranged in sequence. When the outer diameter of the wire material deviates, the intelligent wire diameter controller automatically outputs a feedback control signal to adjust the electrolysis current. The cleaning device 3 includes a rough washing mechanism 6, a neutralization mechanism 7 and a fine washing mechanism 8 which are arranged in sequence. The rough washing mechanism 6 is used for initially washing the tungsten wire 11 to wash away most of the alkali solution on the tungsten wire 11. The neutralization mechanism 7 is used for releasing acid-base neutralization solution to neutralize the alkali solution remaining on the tungsten wire 11. The fine washing mechanism 8 is used for washing the neutralized product on the tungsten wire 11.

[0029] The tungsten wire 11 in the electrolysis device 2 is 12 mm from the liquid surface, which reduces the risk of bubble generation and splashing during the electrolysis process, thereby increasing the electrolyte volume and safety. The precise control of this depth also optimizes the current distribution between the electrode and the tungsten wire, further improving the quality and consistency of the product.

[0030] It should be noted that, in the present embodiment, the wire-releasing device 1 adopts 1 wire-laying motor with 2 wire-collecting motors (1 to 2), the wire-laying width is adjustable from 0 to 120 mm, the wire-laying pitch is adjustable from 0 to 100 wires (the wire-counting wheel adopts a full-circle winding method), and the position of the wire-laying guide wheel is adjustable and convenient to lock, with an adjustment range of 20 mm.

[0031] The number of electrolysis heads of the electrolysis device 2 is 3-6, the electrolysis voltage is 0-36v, and the number of electrodes in each electrolytic cell is 12 pairs in total, which are used to clean tungsten wire 11 with a diameter of 0.08mm-0.015mm. The six working heads are independently controlled and can work independently. These parameters have been precisely calculated and experimentally verified to achieve the best balance between electrolysis efficiency and energy consumption. Compared with traditional technologies, the uniformity and efficiency of the electrolysis process are significantly improved, energy consumption is reduced, and overall environmental friendliness is improved. The wire collecting speed of the wire collecting device 4 is 100-200m / min, and it is controlled by PLC+frequency converter+encoder, with constant speed and constant tension, and the speed fluctuation does not exceed 1m / min. It has fixed length and broken wire parking functions, and the wire collecting shaft runout is ≤0.03mm.

[0032] The intelligent wire diameter controller is centrally displayed, controlled, saved and classified by a computer. When the operator starts the machine, he can set the operator number, customer number, machine number, product batch number, model, specification and other parameter information of each spool to automatically save all the setting parameters and test data, and automatically generate QR codes and various reports required by users. When the outer diameter of the wire material deviates, the system automatically outputs feedback control signals to adjust the electrolytic current to control the wire diameter to always be stable and qualified. The networked laser measurement online monitoring system consists of multiple measurement terminals, a multi-functional server, a data management monitoring center and a dedicated data signal connection line. It can realize 24-hour online automatic measurement, ensure that there are no detection blind spots in time and space, and achieve full process inspection. It can also perform color, sound and light comprehensive alarms, and remind workers to intervene and handle in time when the wire diameter deviates. All test data can be arbitrarily queried based on the set parameters or time, which greatly improves management efficiency and facilitates later tracing and inquiry. All test data automatically generates various reports required by users, which can be archived and printed, saving a lot of labor costs.

[0033] When in use, the tungsten wire 11 passes through the rough washing mechanism 6, the neutralization mechanism 7 and the fine washing mechanism 8 in sequence. When the tungsten wire passes through the rough washing mechanism 6, the rough washing mechanism 6 cleans the alkali solution on the surface of the tungsten wire 11 with hot water. When the tungsten wire 11 passes through the neutralization mechanism 7, the neutralization mechanism 7 neutralizes the alkali solution on the surface of the tungsten wire 11 with an acid-base neutralizing solution. When the tungsten wire 11 passes through the fine washing mechanism 8, the fine washing mechanism 8 cleans and wipes the tungsten wire 11 with clean water. Under the joint action of the rough washing mechanism 6, the neutralization mechanism 7 and the fine washing mechanism 8, the cleanliness of the tungsten wire 11 is improved, and the production quality is improved.

[0034] In the present invention, under the action of the rough washing mechanism 6, the alkali solution attached to the surface of the tungsten wire 11 is cleaned by hot water, under the action of the neutralization mechanism 7, the alkali solution remaining on the surface of the tungsten wire 11 is neutralized by an acid-base neutralizing liquid, and under the action of the fine washing mechanism 8, the neutralized product remaining on the surface of the tungsten wire 11 is cleaned and wiped by clean water. Under the joint action of the three processes of the rough washing mechanism 6, the neutralization mechanism 7 and the fine washing mechanism 8, the cleanliness of the surface of the tungsten wire 11 is improved, and the production quality is improved.

[0035] To rinse the alkali solution on the surface of the tungsten wire 11, please refer to Figure 2 In a preferred embodiment, the rough washing mechanism 6 includes a rough washing tank 61, which contains hot water. A guide wheel 62 is rotatably connected at the top of the rough washing tank 61 for pressing the tungsten wire 11 into the rough washing tank 61.

[0036] When in use, when the tungsten wire 11 passes through the rough washing tank 61, under the action of the guide wheel 62, the tungsten wire 11 is immersed in the rough washing tank 61, and the alkali solution on the surface of the tungsten wire 11 is rinsed with hot water, which improves the fluidity of the alkali solution and has a better cleaning effect.

[0037] To clean the guide wheel 62, refer to Figure 2 and Figure 3 In a preferred embodiment, a support plate 95 is fixedly connected above the guide wheel 62 in the rough washing tank 61, and a scraper 63 is slidably connected to the support plate 95 along the height direction of the rough washing tank 61. A spring 64 is fixedly connected between the scraper 63 and the support plate 95, one end of the spring 64 is fixedly connected to the support plate 95, and the other end of the spring 64 is fixedly connected to the scraper 63. The spring 64 is in a compressed state, and the spring 64 makes the scraper 63 tend to slide toward the guide wheel 62, so that the scraper 63 is movable against the guide wheel 62.

[0038] During use, on the one hand, when the tungsten wire 11 passes through the guide wheel 62, the alkali liquid on the tungsten wire 11 will adhere to the guide wheel 62. After the guide wheel 62 rotates one circle, the alkali liquid on the guide wheel 62 will adhere to the tungsten wire 11 again, affecting the cleanliness of the tungsten wire 11. The scraper 63 cleans the guide wheel 62, reducing the possibility of the alkali liquid on the guide wheel 62 repeatedly adhering to the tungsten wire 11, and improving the cleanliness of the tungsten wire 11. On the other hand, when the tungsten wire 11 moves along the guide wheel 62, it will cause certain wear on the guide wheel 62, affecting the production quality of the tungsten wire 11. The scraper 63 can play a certain grinding role on the guide wheel 62, improve the smoothness of the surface of the guide wheel 62, and thus improve the production quality of the tungsten wire 11.

[0039] To improve flushing performance, please refer to Figure 2In a preferred embodiment, a liquid inlet pipe 65 is fixedly connected to one side of the rough washing tank 61, a guide groove 66 for the tungsten wire 11 to pass through is fixedly connected below the guide wheel 62 in the rough washing tank 61, and a liquid outlet pipe 67 is fixed to the other side of the rough washing tank 61, and the liquid inlet pipe 65, the guide groove 66 and the liquid outlet pipe 67 are aligned.

[0040] When in use, the tungsten wire 11 passes through the guide groove 66. Under the joint action of the liquid inlet pipe 65, the guide groove 66 and the liquid outlet pipe 67, the hot water in the rough washing tank 61 is directed to move along the length direction of the tungsten wire 11. On the one hand, the impact force of the hot water is increased. On the other hand, the impurities on the surface of the tungsten wire 11 can be quickly washed away, reducing the possibility of impurities repeatedly adhering to the tungsten wire 11, improving the cleanliness of the surface of the tungsten wire 11, and improving the production quality.

[0041] To improve the cleanliness of hot water, please refer to Figure 3 In a preferred embodiment, a filter tank 68 is fixedly connected to one side of the rough washing tank 61, a return pipe 69 is fixedly connected to one side of the filter tank 68, a pump body 91 is installed on the return pipe 69, the liquid outlet pipe 67, the filter tank 68 and the return pipe 69 are connected in sequence, a filter plate 92 is installed in the filter tank 68, and the filter plate 92 is inclined at 30°.

[0042] When in use, under the action of the pump body 91, hot water flows between the rough washing tank 61 and the filter tank 68, and impurities on the tungsten wire 11 pass through the liquid outlet pipe 67 into the filter tank 68 and fall onto the filter plate 68, thereby improving the cleanliness of the hot water and the cleanliness of the tungsten wire 11. The filter plate 68 is set in an inclined state, so that the impurities are concentrated on one side of the filter plate 68, which is convenient for the later treatment of impurities, convenient operation, and improved production efficiency.

[0043] To neutralize the alkali solution on the tungsten wire 11, please refer to Figure 4 In a preferred embodiment, the neutralization mechanism 7 includes a liquid storage tank 71, which contains acid-base neutralization liquid. A drain pipe 72 is fixedly connected to the bottom of the liquid storage tank 71. The drain pipe 72 extends along the height direction of the liquid storage tank 71. The drain pipe 72 is located directly above the tungsten filament 11. A flow valve 73 is installed on the drain pipe 72. A recovery box 74 is fixedly connected to the bottom of the liquid storage tank 71, and the top of the recovery box 74 is open.

[0044] When in use, when the tungsten wire 11 passes through the drain pipe 72, the flow rate of the acid-base neutralizing solution is controlled by using the flow valve 73 according to the diameter of the tungsten wire 11. The acid-base neutralizing solution in the liquid storage tank 71 passes through the drain pipe 72 and drips onto the tungsten wire 11 to neutralize the alkali solution on the tungsten wire 11. The excess acid-base neutralizing solution and the alkali solution fall into the recovery tank 74. This method effectively reduces the amount of acid-base neutralizing solution, saves energy and protects the environment, and is consistent with the concept of sustainable development.

[0045] To improve the neutralization effect, please refer to Figure 5 In a preferred embodiment, a bracket 75 is fixedly connected to one side of the liquid storage tank 71, and a sleeve 76 is provided on the bracket 75 for the tungsten wire 11 to pass through. The end of the sleeve 76 away from the liquid storage tank 71 is connected to the air source through an air pipe 77. The air source is generally an air pump. Four exhaust holes 78 are arranged on the inner side of the sleeve 76. The four exhaust holes 78 are all inclined at forty-five degrees, and the four exhaust holes 78 are all facing the tungsten wire 11.

[0046] When in use, the tungsten filament 11 passes through the sleeve 76, and the gas discharged from the gas source passes through the exhaust hole 78 and blows onto the tungsten filament 11 along the length direction of the tungsten filament 11. Under the action of the airflow, the fluidity of the acid-base neutralization liquid is improved, so that the acid-base neutralization liquid and the alkaline solution are mixed more evenly, further improving the neutralization effect, improving the cleanliness of the tungsten filament 11, and improving the production quality.

[0047] To further enhance the neutralization effect, please refer to Figure 6 In a preferred embodiment, the sleeve 76 is connected to the bracket 75 for axial rotation along the tungsten wire 11, and a motor 79 is installed on the bracket 75 on one side of the sleeve 76. A driving gear 93 is coaxially fixedly connected to the output shaft of the motor 79, and a driven gear ring 94 meshing with the driving gear 93 is coaxially fixedly connected to the sleeve 76.

[0048] When in use, under the driving action of the motor 79 and the transmission action of the driving gear 93 and the driven gear ring 94, the sleeve 76 rotates 360° along the axial direction of the tungsten filament 11, so that the airflow discharged from the exhaust hole 78 is blown onto the tungsten filament 11 more evenly, further improving the neutralization effect, improving the cleanliness of the tungsten filament 11, and improving the production quality.

[0049] To clean up the neutralizer, refer to Figure 7 In a preferred embodiment, the fine washing mechanism 8 includes a fine washing tank 81, which is filled with clean water. A pressure wheel 82 is rotatably connected at the top of the fine washing tank 81 to press the tungsten wire 11 into the fine washing tank 81, and an ultrasonic generator 83 is fixedly connected at the bottom of the fine washing tank 81.

[0050] During use, when the tungsten wire 11 passes through the fine washing tank 81 , the pressing wheel 82 presses the tungsten wire 11 into the fine washing tank 81 , and under the action of the ultrasonic generator 83 , the clean water in the fine washing tank 81 generates ultrasonic vibrations to completely clean the neutralized substances on the tungsten wire 11 .

[0051] To make the tungsten filament 11 dry quickly, please refer to Figure 8In a preferred embodiment, a frame 96 is fixedly connected to the side of the fine washing tank 81 away from the bracket 75, and two wiping plates 84 are fixedly connected to the frame 96. The wiping plates 84 include a plate body 85 and a sponge 86 fixedly connected to the plate body 85. The two sponges 86 are respectively in contact with the top and bottom of the tungsten wire 11. Liquid storage chambers 87 are opened in the two plate bodies 85. Alcohol is contained in the liquid storage chamber 87, and the liquid storage chamber 87 is connected to the sponge 86.

[0052] When in use, the sponge 86 wipes the tungsten wire 11, cleans the water droplets attached to the surface of the tungsten wire 11, improves the dryness of the tungsten wire 11, and reduces the possibility of dust repeatedly adhering to the surface of the tungsten wire 11. The alcohol in the liquid storage chamber 87 enters the sponge 86, and the sponge 86 applies the alcohol to the tungsten wire 11, further accelerating the volatilization of the water droplets, further accelerating the drying of the tungsten wire 11, further improving the cleanliness of the tungsten wire 11, and further improving the production quality.

[0053] In order to better understand the present invention, the following Figure 1 - Figure 8 The working principle of the technical solution of a tungsten wire processing equipment of the present invention is described in detail: the tungsten wire 11 passes through the rough washing mechanism 6, the neutralization mechanism 7 and the fine washing mechanism 8 in sequence. When the tungsten wire 11 passes through the rough washing mechanism 6, the rough washing mechanism 6 cleans the alkali solution on the surface of the tungsten wire 11 with hot water. When the tungsten wire 11 passes through the neutralization mechanism 7, the neutralization mechanism 7 neutralizes the alkali solution on the surface of the tungsten wire 11 with an acid-base neutralizing solution. When the tungsten wire 11 passes through the fine washing mechanism 8, the fine washing mechanism 8 cleans and wipes the tungsten wire 11 with clean water. Under the joint action of the rough washing mechanism 6, the neutralization mechanism 7 and the fine washing mechanism 8, the cleanliness of the tungsten wire 11 is improved, and the production quality is improved.

[0054] In summary, the electrolysis equipment of the present invention realizes intelligent control of wire diameter through the intelligent wire diameter controller, realizes comprehensive intelligent management and control of the tungsten wire production process, improves the consistency of production efficiency and product quality, and adds two key steps of acid neutralization and alkali solution treatment and ultrasonic cleaning after the traditional cleaning process, which greatly improves the surface cleanliness of the tungsten wire and the stability of product quality. The present invention significantly improves the production efficiency and surface quality of tungsten wire through precise current control technology and advanced cleaning process optimization, and is particularly suitable for meeting the strict requirements of high-tech industries such as photovoltaics for high-performance tungsten wire.
