Description

Technical Field

[0001] This invention belongs to the field of diamond wire processing technology, specifically a diamond wire drying and spraying processing device that integrates hot water washing. Background Technology

[0002] Diamond wire is a new type of cutting wire in which diamond microparticles are fixed onto a high-strength steel wire matrix by electroplating or resin bonding. Its surface is uniformly distributed with abrasive with high hardness, which makes it have significant advantages such as high cutting efficiency, low material loss and good slice quality in the cutting and processing of hard and brittle materials such as photovoltaic silicon wafers, sapphire and magnetic materials. It has become a key consumable in the field of precision machining.

[0003] Traditional diamond wire electroplating equipment typically employs a horizontal structure. The diamond wire undergoes multiple processes, including wire feeding, alkaline washing, water washing, acid washing, water washing, pre-plating, spraying, sandblasting, thickening, post-treatment, visual inspection, and wire take-up. The spraying process mainly involves spraying and curing electroplating insulating material onto the passing steel wire busbar. The spraying station sprays the insulating material intermittently and in segments, forming segments of insulating shielding bands on the nickel layer surface. Subsequently, when entering the sandblasting tank for electroplating, the areas with the insulating film are non-conductive, making it difficult to deposit nickel and diamond. The exposed nickel areas without the insulating film are sandblasted normally and the diamond is solidified.

[0004] In the process of drying, spraying, and electroplating insulating materials onto diamond wire, the traditional method typically uses a spraying device to intermittently spray masking ink onto the passing steel busbar, followed by drying and curing to achieve a localized masking effect. This spraying device is a machine used to spray insulating masking ink onto the steel wire. Traditional processes usually employ intermittent spraying, meaning that after each spraying, a waiting period is required before the next spraying. This spraying and drying process is divided into different areas, one for spraying and another for drying. Traditionally, there is a distance between the drying area and the spraying device, and the heat released during drying is not recovered but instead dissipated to the outside, easily leading to resource waste.

[0005] Therefore, the present invention provides a diamond wire drying and spraying processing device with integrated hot water washing. Summary of the Invention

The machine box is placed below the spraying box. The hot water washing component cleans the pre-plated steel wire busbar, and the first drying component performs a primary drying process to reduce residual moisture. Subsequently, the steel wire busbar enters the spraying box, and two pumps draw electroplating insulating masking ink from the first liquid storage tank through a liquid extraction pipe.

Waste heat from the first drying component is sent to the preheating chamber via a first electromagnetic multi-way valve, heating the ink in the first liquid storage tank at a high temperature. Excess heat after heat exchange is sent to the constant temperature buffer zone via a flow component, performing secondary heat exchange on the second liquid storage tank. Lower-temperature waste heat discharged from the second drying component is sent to the heat tracing zone via a second electromagnetic multi-way valve, insulating the third liquid storage tank. Excess heat after heat exchange is also sent to the constant temperature buffer zone. This partitioned design achieves tiered utilization of waste heat at different temperatures, reducing heat waste. Simultaneously, partitioning avoids thermal interference between temperature zones, ensuring stable ink temperatures in each liquid storage tank and guaranteeing the spraying effect.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 6As shown in the embodiment of the present invention, a diamond wire drying and spraying processing device with integrated hot water washing includes a frame 1; a housing 11 is fixedly connected to the frame 1 near the center; a first liquid storage tank 12 is fixedly connected inside the housing 11; two spraying boxes 13 are fixedly connected to the frame 1, and the two spraying boxes 13 are located above the housing 11; two sprayers 14 are fixedly connected inside the spraying boxes 13; two pumps 15 are fixedly connected to the upper surface of the housing 11, and the output ends of the two pumps 15 are respectively connected to the two sprayers 14; a liquid extraction pipe 16 is fixedly connected between the input end of the pump 15 and the first liquid storage tank 12, and the liquid extraction pipe 16 penetrates the housing 11; two hot water washing components 17 are fixedly connected to the frame 1; Two primary drying components 18 are fixedly connected to the frame 1 between the hot water washing component 17 and the spraying box 13; a secondary drying component 19 is fixedly connected to the end of the frame 1 away from the primary drying component 18 at the end of the spraying box 13; two connectors 191 are fixedly connected to the housing 11, and the two connectors 191 are respectively connected to the primary drying component 18 and the secondary drying component 19 through long pipes; the diamond wire electroplating device adopts a horizontal structure, and the diamond wire is formed through multiple processes such as wire feeding, alkaline washing, water washing, acid washing, water washing, pre-plating, spraying, sanding, thickening, post-treatment, visual inspection and wire take-up. During the process of drying and electroplating insulating material on the diamond wire in the spraying process, the hot water washing component 17, the primary drying component 18, and the spraying box 13 are sequentially connected. 3. The second drying assembly 19 is fixed on the frame 1 and can be dried by electric heating and ventilation. The casing 11 is fixed below the spraying box 13. The frame 1 is equipped with two processing lines. The hot water washing assembly 17 is used to wash the pre-plated steel wire busbar with hot water, and the first drying assembly 18 performs a drying treatment on the steel wire busbar after hot water washing to reduce the moisture residue on the steel wire busbar. Then the steel wire busbar passes through the spraying box 13. Two pumps 15 draw electroplating insulating masking ink stored in the first liquid storage tank 12 through two liquid extraction pipes 16, and send it to the sprayer 14 in the spraying box 13 through the output end of the pump 15 for intermittent spraying, spraying it on the passing steel wire busbar. Then the steel wire busbar enters the second drying assembly. The internal secondary drying of component 19 serves to achieve segmented masking of the steel busbar. When the steel busbar is sprayed with electroplating insulating masking ink in the spraying box 13, the two connectors 191 are connected to the first drying component 18 and the second drying component 19, respectively. Some of the residual heat discharged from the first drying component 18 and the second drying component 19 can be sent to the casing 11. The residual heat can preheat the electroplating insulating masking ink in the first liquid storage tank 12, avoiding the problem of increased viscosity and decreased fluidity of the electroplating insulating masking ink due to excessively low temperature, ensuring stable and uniform ink spraying and uniform masking. At the same time, the residual heat discharged during the drying process is recovered and utilized, eliminating the need for additional heating equipment for ink preheating and reducing heat energy waste.After the coated steel wire busbar enters the second drying unit 19 for secondary drying, the ink will solidify to form a stable masking layer. Then it can proceed to the next sandblasting process to complete subsequent processing.

[0024] A second liquid storage tank 2 is fixedly connected to the interior of the chassis 11 near its center; a third liquid storage tank 21 is also fixedly connected to the interior of the chassis 11, with the first liquid storage tank 12 and the third liquid storage tank 21 located on either side of the second liquid storage tank 2. The heights of the first liquid storage tank 12, the second liquid storage tank 2, and the third liquid storage tank 21 within the chassis 11 are arranged from low to high. A liquid storage check valve 22 is fixedly connected to one side of each of the first liquid storage tank 12 and the second liquid storage tank 2; a flow pipe 23 is fixedly connected to the liquid storage check valve 22, with two flow pipes 23 located between the first liquid storage tank 12 and the second liquid storage tank 2, and between the second liquid storage tank 2 and the third liquid storage tank 21, respectively. The chassis 11 is internally equipped with a partitioning mechanism to divide the internal heat exchange into zones. When electroplating insulating masking ink is sprayed onto the steel wire busbar, the No. 2 and No. 3 storage tanks 21 are fixed inside the chassis 11 and located to one side of the No. 1 storage tank 12. A large amount of electroplating insulating masking ink is stored in the No. 3 storage tank 21, which is placed at a high position inside the chassis 11. The No. 2 storage tank 2 is located at the center height inside the chassis 11, while the No. 1 storage tank 12 is located at a low position on one side inside the chassis 11. The No. 1 storage tank 12, the No. 2 storage tank 2, and the No. 3 storage tank 21 are all connected by a one-way valve. Connected to pipe 22 and flow pipe 23, when ink in the first storage tank 12 is drawn out, the second storage tank 2 replenishes the first storage tank 12 through flow pipe 23 and storage check valve 22. When the ink in the second storage tank 2 decreases, the third storage tank 21 replenishes the second storage tank 2 through flow pipe 23 and storage check valve 22. The storage check valve 22 prevents ink backflow and ensures stable downward replenishment. The volumes of the third storage tank 21, the second storage tank 2, and the first storage tank 12 are arranged from largest to smallest, and the interior of the casing 11 is divided into multiple areas by a partition mechanism. Different preheating temperatures are set according to the different areas. The first drying component 1... The temperature inside drying component 8 is higher than that inside drying component 19. Drying component 18 removes water at high temperature, while drying component 19 can only cure ink. Therefore, the residual heat introduced into drying component 18 is at a higher temperature, which can quickly preheat the ink stored in small-capacity storage tank 12, keeping the ink in storage tank 12 at a stable operating temperature. The ink stored in large-capacity storage tank 21 can be kept warm by the residual heat introduced into drying component 19. This allows for full utilization of residual heat at different temperatures, ensuring the utilization rate of residual heat and keeping ink of different capacities at different temperatures, thus ensuring stable viscosity during ink spraying.

[0025] The separation mechanism includes a first vertical partition 3, a first horizontal partition 31, a second vertical partition 32, a third vertical partition 33, a second horizontal partition 34, a first electromagnetic multi-way valve 37, a second electromagnetic multi-way valve 38, and a flow assembly; the first vertical partition 3 is fixedly connected to the inside of the housing 11 on the side near the first liquid storage tank 12; the first horizontal partition 31 is fixedly connected to the top side of the first vertical partition 3; the second vertical partition 32 is fixedly connected to the bottom center of the first horizontal partition 31; the third vertical partition 33 is fixedly connected to the end of the first horizontal partition 31 away from the first vertical partition 3; and the second horizontal partition 34 is fixedly connected to the center of one side of the third vertical partition 33. A preheating chamber 35 is provided between the first vertical partition 3 and the second vertical partition 32; a heat tracing zone 36 is provided inside the chassis 11 above the second horizontal partition 34; the first electromagnetic multi-way valve 37 is fixed to a connector 191, located above the first liquid storage tank 12 inside the chassis 11, and the second electromagnetic multi-way valve 38 is fixed to another connector 191, located below the third liquid storage tank 21 inside the chassis 11, with the output end of the second electromagnetic multi-way valve 38 penetrating the second horizontal partition 34 and located within the heat tracing zone 36; a heat tracing zone 36 is provided between the second vertical partition 32 and the third vertical partition 33. A constant temperature buffer zone 4 is provided. The flow assembly is located at the center inside the chassis 11. The flow assembly is used to send the heat from the overpressure in the preheating chamber 35 and the heat tracing zone 36 into the constant temperature buffer zone 4 for collection. When the interior of the chassis 11 is preheated in zones, the first vertical partition 3, the first horizontal partition 31, the second vertical partition 32 and the chassis 11 separate the preheating chamber 35; the third vertical partition 33, the second horizontal partition 34 and the chassis 11 separate the heat tracing zone 36; the first horizontal partition 31, the second vertical partition 32, the third vertical partition 33 and the chassis 11 separate the constant temperature buffer zone 4. The preheating chamber 35 and the heat tracing zone 36 are located on both sides of the constant temperature buffer zone 4. The first electromagnetic multi-way valve 37 is fixed on a connector 191 and is located above the first liquid storage tank 12. The second electromagnetic multi-way valve 38 is fixed on another connector 191 and is located below the heat tracing zone 36. The waste heat introduced by the first drying component 18 is sent to the preheating chamber 35 connected by the first electromagnetic multi-way valve 37. The high-temperature waste heat directly heats up the ink in the first liquid storage tank 12 located below the preheating chamber 35. The excess waste heat after heat exchange can be transported to the constant temperature buffer zone 4 located in the middle through the flow component to perform secondary heat exchange on the ink in the second liquid storage tank 2.The slightly lower-temperature waste heat introduced into the second drying component 19 is directly sent to the heat tracing zone 36 connected by the second electromagnetic multi-way valve 38 to keep the ink in the third liquid storage tank 21 located below the heat tracing zone 36 warm. Excess waste heat after heat exchange is also sent to the constant temperature buffer zone 4 through the flow component to complete heat exchange, making full use of waste heat at different temperatures and reducing heat waste caused by direct exhaust. At the same time, the zoned structure can confine waste heat at different temperatures to corresponding areas, reducing mutual interference between heat from different temperature zones, ensuring the temperature stability of the ink in each storage area, and ensuring stable performance during ink retrieval and spraying.

[0026] The flow assembly includes a first electromagnetic check valve 41 and a second electromagnetic check valve 42. The first electromagnetic check valve 41 is fixed to the second vertical partition 32, and its output end faces the constant temperature buffer zone 4. The second electromagnetic check valve 42 is fixed to the third vertical partition 33, and its output end faces the constant temperature buffer zone 4. When the residual heat introduced by the first electromagnetic multi-way valve 37 accumulates excessively in the preheating chamber 35, exceeding the set threshold, the first electromagnetic check valve 41 automatically opens, allowing the excess residual heat to flow into the constant temperature buffer zone 4. When the excess heat introduced by the second electromagnetic multi-way valve 38 accumulates excessively in the heat tracing zone 36, exceeding the set threshold, the second electromagnetic one-way valve 42 automatically opens, allowing the excess heat to be introduced into the constant temperature buffer zone 4. The excess heat in the preheating chamber 35 and the excess heat in the heat tracing zone 36 can be mixed and sent into the central constant temperature buffer zone 4 to heat exchange the ink stored in the central second liquid storage tank 2. This fully utilizes the excess heat after heat exchange, ensuring the utilization rate of the excess heat, reducing heat waste, and at the same time avoiding excessive pressure in a single temperature zone, ensuring the structural stability of the heat exchange process. When setting the thresholds, please note the following: For solenoid check valve 41, the initial pressure threshold for overpressure activation is 120-125 Pa, and the threshold for closure is 80-85 Pa. For solenoid check valve 42, the initial pressure threshold for overpressure activation is 90-95 Pa, and the threshold for closure is 50-55 Pa. For solenoid multi-way valve 37, the pressure threshold for heat storage switching is 150-155 Pa, and the lower limit cut-off threshold is 60-65 Pa. For solenoid multi-way valve 38, the pressure threshold for heat storage switching is 110-115 Pa, and the lower limit cut-off threshold is 40-45 Pa. Adjust the thresholds according to the actual working conditions. All temperature and pressure initial thresholds are factory-set with a ±20% margin for manual adjustment, which can be corrected on-site based on production line speed, workshop ambient temperature, and different viscosity ink types.

[0027] Two heat exchange tubes 5 are fixedly connected to the No. 1 storage tank 12, and the two heat exchange tubes 5 are wrapped around the No. 1 storage tank 12. One end of each heat exchange tube 5 is connected to one of the two output ends of the No. 1 electromagnetic multi-way valve 37. Two heat exchange tubes 51 and 52 are fixedly connected to the No. 2 storage tank 2, and the two heat exchange tubes 51 and 52 are wrapped around the No. 2 storage tank 2. One end of heat exchange tube 51 is connected to the output end of the No. 1 electromagnetic one-way valve 41, and one end of heat exchange tube 52 is connected to the output end of the No. 2 electromagnetic one-way valve 42. The output end is connected; a fourth heat exchange tube 53 is fixedly connected to the third liquid storage tank 21, and the fourth heat exchange tube 53 surrounds the third liquid storage tank 21. One end of the fourth heat exchange tube 53 is connected to the output end of the second electromagnetic multi-way valve 38; when heat exchange is performed on the ink in the first liquid storage tank 12, the second liquid storage tank 2, and the third liquid storage tank 21, the residual heat from the first drying component 18 entering the first electromagnetic multi-way valve 37 enters the two first heat exchange tubes 5. The heat surrounds the outside of the first liquid storage tank 12 for close heat exchange, which can make the heat exchange and temperature rise more uniform and quickly heat the first liquid storage tank 12. The ink in the storage tank 12 heats up, and after heat exchange, it is discharged from the other end of the first heat exchange tube 5 into the preheating chamber 35. Excess heat discharged into the central constant temperature buffer zone 4 by the first electromagnetic check valve 41 and the second electromagnetic check valve 42 enters the second heat exchange tube 51 and the third heat exchange tube 52 respectively, surrounding the outside of the second storage tank 2 to exchange heat and maintain the temperature of the ink inside. After heat exchange, it is discharged from the other end of the second heat exchange tube 51 and the third heat exchange tube 52 into the constant temperature buffer zone 4, maintaining the temperature of the ink in the second storage tank 2, facilitating timely transfer to the first storage tank. 12 When replenishing ink, the temperature of the replenished ink can quickly meet the usage requirements; the residual heat from the second drying component 19, which is introduced into the second electromagnetic multi-way valve 38, enters the fourth heat exchange tube 53 and surrounds the outside of the third liquid storage tank 21, continuously keeping the ink stored in the third liquid storage tank 21 at a stable temperature. After heat exchange, the ink is discharged from the other end of the fourth heat exchange tube 53 into the heat tracing zone 36. The surrounding heat exchange structure makes the heat exchange more uniform, avoids uneven local temperature of the ink, and ensures the stability of ink viscosity and fluidity.

[0028] The casing 11 has a first heat storage zone 6 located on the side of the first vertical partition 3 away from the preheating chamber 35. The output end of the first electromagnetic multi-way valve 37 is fixedly connected to a first guide pipe 61, which passes through the first vertical partition 3 and connects to the first heat storage zone 6. When too much waste heat is recovered from the preheating chamber 35 and the constant temperature buffer zone 4, the first electromagnetic multi-way valve 37 is controlled to close the output end that flows into the preheating chamber 35 and open the output end connected to the first guide pipe 61, so that the waste heat that continues to flow into the first drying component 18 can be recovered into the first heat storage zone 6. This system stores heat to prevent safety hazards caused by continuous pressure increases in the heat exchange chamber. It also stores excess heat for later use, preventing direct waste discharge and ensuring high heat recovery rates. When the heat in the preheating chamber 35 and the constant temperature buffer zone 4 decreases, the first guide pipe 61 can be connected to the preheating chamber 35. This allows the waste heat stored in the first heat storage zone 6 to be sent to the preheating chamber 35 through the first guide pipe 61 and the first electromagnetic multi-way valve 37, maintaining temperature stability in the preheating chamber 35 and the constant temperature buffer zone 4. This, in turn, ensures stable ink temperature in the first liquid storage tank 12, reducing additional energy consumption.

[0029] The casing 11 contains a second heat storage zone 7, which is located at the bottom of the second partition plate 34. The output end of the second electromagnetic multi-way valve 38 is fixedly connected to a second guide pipe 71, which is located inside the second heat storage zone 7. When the second drying assembly 19 receives excessive waste heat into the heat tracing zone 36, the second electromagnetic multi-way valve 38 is controlled to close the output end into the heat tracing zone 36 and open the output end connected to the second guide pipe 71. This allows the waste heat continuing to be supplied by the second drying assembly 19 to be recovered and stored in the second heat storage zone 7, preventing heat loss during heat tracing. The continuous increase in pressure within the hot zone 36 poses a safety hazard, but it also allows for the storage of excess heat for later use, preventing direct waste from external discharge and ensuring a high rate of waste heat recovery. When the heat in the hot zone 36 and the constant temperature buffer zone 4 decreases, the second guide pipe 71 can be connected to the hot zone 36 simultaneously, allowing the waste heat stored in the second heat storage zone 7 to be sent to the hot zone 36 through the second guide pipe 71 and the second electromagnetic multi-way valve 38, maintaining the temperature stability in the hot zone 36 and the constant temperature buffer zone 4, thereby ensuring the stability of the ink temperature in the third liquid storage tank 21 and reducing the consumption of additional energy.

[0030] A first side support plate 8 is fixedly connected to the bottom of the first liquid storage tank 12; a second side support plate 81 is fixedly connected to the bottom of the second liquid storage tank 2; a third side support plate 82 is fixedly connected to the bottom of the third liquid storage tank 21, and the third side support plate 82 passes through the second transverse partition 34; the first side support plate 8, the second side support plate 81, and the third side support plate 82 are all made of metal; when the ink is preheated using residual heat, the first side support plate 8, the second side support plate 81, and the third side support plate 82 respectively support the bottom of the first liquid storage tank 12, the second liquid storage tank 2, and the third liquid storage tank 21, providing stable support, and the first side support plate 8, the second side support plate 81, and the third side support plate 82... The first, second, and third liquid storage tanks 82 are respectively supported at the bottom of the first liquid storage tank 12, the second liquid storage tank 2, and the third liquid storage tank 21, and are attached to both sides of their bottoms. The first, second, and third side support plates 8 and 82 are made of metal. They not only provide support, but also absorb heat through their material and exchange heat at the bottom and sides of the first, second, and third side support plates 8 and 82. One end of the extraction pipe 16 is located at the bottom of the extraction point in the first liquid storage tank 12. The two flow pipes 23 are connected to the bottom of the second and third liquid storage tanks 21, thereby ensuring the uniformity of ink heat exchange and the temperature of extraction and replenishment, and stabilizing the viscosity and flowability of the ink during use.

[0031] A connecting pipe 9 is fixed to the chassis 11 via an electromagnetic control valve, and the connecting pipe 9 connects to the interior of the constant temperature buffer zone 4. Two exhaust pipes 91 are fixed to the connecting pipe 9, and the two exhaust pipes 91 connect to two spraying boxes 13 respectively. When the waste heat recovered in the constant temperature buffer zone 4 is too high, the electromagnetic control valve connected to the connecting pipe 9 is opened, so that the excessive heat in the constant temperature buffer zone 4 can be sent to the spraying box 13 through the connecting pipe 9 and the exhaust pipes 91, preheating the steel wire busbar being transported and sprayed in the spraying box 13. This reduces the problem of uneven curing of the masking layer and reduced adhesion caused by the low temperature steel wire busbar passing through the interior of the spraying box 13. At the same time, the excess heat is utilized to avoid heat accumulation leading to excessive pressure in the constant temperature buffer zone 4, ensuring the operational stability of the partitioned heat exchange structure.

[0032] like Figures 1 to 6As shown, the two extraction pipes 16 have a double-layer hollow structure inside, and the outer layer of both extraction pipes 16 is made of metal. Multiple conical holes 92 are opened on the outside of the two extraction pipes 16, and these conical holes 92 are located inside the preheating chamber 35. When the pump 15 extracts the electroplating insulating masking ink from the first storage tank 12 through the extraction pipes 16, the metal outer layer of the extraction pipes 16 can absorb the recovered residual heat, thereby continuously keeping the ink warm during the extraction process. This prevents the ink temperature from dropping during delivery to the nozzle, which would lead to an increase in viscosity and affect the uniformity of spraying. The multiple conical holes 92 on the outer layer of the extraction pipes 16 allow residual heat to enter the hollow interior of the extraction pipes 16, accumulating the residual heat in the hollow cavity. The small inward opening of the conical holes 92 ensures the heat exchange and insulation effect, guaranteeing the temperature stability and uniformity of the ink coating during the process from the storage chamber to the nozzle.
