Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of diamond wire manufacturing, especially relates to a diamond wire surface treatment system with automatic supplement function. BACKGROUND

[0002] Diamond wire, namely diamond cutting wire, is a kind of cutting tool made by embedding a layer of diamond particles on the base body of high-strength steel wire and other parent wires through specific process. Because the diamond embedded on its surface has extremely high hardness and wear resistance, diamond wire shows excellent performance in the cutting field. In the photovoltaic industry, diamond wire is widely used in slicing processing of semiconductor materials such as single crystal silicon and polycrystalline silicon, which can significantly improve slicing efficiency and quality and reduce production cost. In the cutting processing field of optical glass, gem and other hard and brittle materials, diamond wire has become one of the mainstream cutting tools due to its high precision and low loss characteristics.

[0003] The production of diamond wire generally includes the main steps of parent wire selection and pretreatment, diamond particle coating, solidification and post-treatment. Parent wire pretreatment is the key link to ensure the quality of diamond wire, which usually includes surface cleaning processes such as water washing, alkali washing and acid washing to remove impurities such as oil stains, rust marks and oxide layers on the surface of parent wire, so that the surface of parent wire reaches a clean and activated state, creating good conditions for the firm adhesion of diamond particles in the subsequent process. On the pretreated surface of the parent wire, diamond particles are uniformly fixed on the parent wire by electroplating, resin bonding or brazing, etc. to form diamond wire with cutting ability. Finally, through post-treatment processes such as solidification and heat treatment, the performance and stability of diamond wire are further improved.

[0004] In the production process of diamond wire, the surface cleaning process plays a crucial role. First of all, thoroughly removing oil stains and impurities on the surface of the parent wire can prevent these contaminants from affecting the bonding force between diamond particles and the parent wire in the subsequent electroplating or bonding process, ensuring that diamond particles are not easy to fall off during use, improving cutting performance and service life. Secondly, removing the oxide layer and rust marks on the surface of the parent wire can make the surface of the parent wire present a fresh metal active surface, which is conducive to the deposition of metal ions in the electroplating process, making the plating layer more uniform and dense, thereby enhancing the overall strength and wear resistance of the diamond wire. In addition, good surface cleaning can also ensure the flatness and smoothness of the parent wire surface, improving the cutting precision and surface quality of the diamond wire.

[0005] In the surface cleaning link of the existing diamond wire manufacturing process, a mother tank is usually used to contain cleaning solution for cleaning operation. However, there is currently a lack of real-time detection means for the liquid level of the mother tank, and only manual periodic inspection can be relied on. Manual inspection not only requires a large amount of labor cost, but also has a long inspection cycle and cannot timely find the subtle changes of the liquid level. When the liquid level is too low, the cleaning effect may be affected because the cleaning solution cannot fully soak the busbar in some areas. When the liquid level is too high, the cleaning solution may overflow, which not only wastes resources but also pollutes the production environment.

[0006] Manual liquid supplement is the main way to supplement cleaning solution at present, which can only supplement liquid according to fixed time intervals and preset amounts. Since the consumption speed of cleaning solution is affected by many factors such as the number of busbar cleaning, cleaning time, cleaning solution concentration, etc. during the cleaning process, the regular and quantitative liquid supplement method cannot accurately meet the actual production needs. When the actual consumption speed is greater than the liquid supplement speed, the concentration and liquid level of the cleaning solution will gradually decrease, resulting in a decrease in cleaning effect. Conversely, when the actual consumption speed is less than the liquid supplement speed, it will cause waste of cleaning solution and may also affect the process parameters of the cleaning solution, such as concentration, pH value, etc., thereby affecting the surface treatment quality of the diamond wire.

[0007] Some enterprises use a liquid supplement pump for quantitative liquid supplement, but this method also has obvious shortcomings. The liquid supplement amount of the liquid supplement pump is preset and cannot be dynamically adjusted according to the real-time changes of the liquid level of the mother tank. In actual production, due to the influence of various factors, the liquid level of the mother tank will fluctuate. When the liquid level is low, the liquid supplement pump may supplement liquid at a fixed speed, but due to the relatively slow liquid supplement speed, the liquid level may remain at a low level and cannot be restored to the normal working liquid level in time. When the liquid level is high, the liquid supplement pump continues to supplement liquid at the set amount, which may continuously increase the liquid level and even cause the liquid to overflow the mother tank. The instability of the liquid level not only affects the cleaning effect, but also may cause damage to the equipment, increase maintenance costs and production risks. Practical new type content

[0010] A kind of diamond wire surface treatment system with automatic supplement function includes a liquid storage structure for storing cleaning solution, a liquid delivery pipe connected to the liquid storage structure and a liquid supply end, a control valve for controlling the on-off of the liquid delivery pipe, a liquid level acquisition device arranged in the liquid storage structure, and a control system.

[0011] The liquid storage structure comprises a plurality of liquid storage tanks arranged corresponding to the process flow of each station of the diamond wire production line, and the control valve is used for automatically supplementing the cleaning liquid in the liquid storage tank by opening and closing the control valve.

[0012] The control system is provided with a liquid supplementing position and a liquid supplementing stop position corresponding to different liquid storage tanks, and the opening and closing of the control valve are controlled according to the feedback information of the liquid level collecting device.

[0013] As a further improvement of the utility model, the control system has a liquid supplementing time length setting function, and the interval time from opening to closing of the control valve is controlled according to the liquid supplementing time length when the liquid level in the liquid storage tank is lower than the liquid supplementing position.

[0014] As a further improvement of the utility model, the control system further has a liquid supplementing period detection setting function, the liquid supplementing time length is increased when the liquid level in the liquid storage tank is lower than the liquid supplementing position within one liquid supplementing period after starting liquid supplementing, and the liquid supplementing time length is decreased when the liquid level in the liquid storage tank is higher than the liquid supplementing position within one liquid supplementing period after starting liquid supplementing.

[0019] As a further improvement of the utility model, the additive storage tank comprises a pre-plating acid tank arranged corresponding to the pre-plating process, a segmentation agent storage tank and a sanding acid tank arranged corresponding to the sanding process, and a brightener storage tank and a thickening acid tank arranged corresponding to the thickening process.

[0020] As a further improvement of the utility model, the control valve is a pneumatic valve.

[0021] As a further improvement of the utility model, the system further comprises a manual control valve arranged on the infusion pipe corresponding to the liquid storage tank, which controls the opening and closing of the cleaning liquid entering the liquid storage tank. Advantages

[0022] The application adopts an advanced closed-loop control mode, uses a liquid level collection device to detect the liquid level in the liquid storage tank in real time, and feeds back the liquid level information to the control system. The control system accurately controls the control valve according to the preset replenishment liquid level and stop replenishment position. This closed-loop control mechanism enables the system to respond to small changes in the liquid level in a timely manner, achieving accurate control of the liquid level. Compared with the traditional manual inspection and liquid replenishment method, the problem of liquid overflow due to late or inaccurate manual operation or insufficient cleaning effect due to low liquid level is avoided, ensuring that the diamond wire is in a stable and suitable cleaning liquid level environment in each process, effectively improving the quality and stability of surface treatment.

[0023] The system uses a multiple small replenishment method to replenish the cleaning liquid, and a small amount of cleaning liquid is replenished each time, and the function of automatically adjusting the replenishment amount is combined. The control system dynamically adjusts the replenishment amount each time according to the information fed back by the liquid level collection device and the preset replenishment time and replenishment cycle detection settings. This method not only accurately controls the replenishment amount to match the actual cleaning liquid consumption rate, but also avoids the large impact of one-time large replenishment on key process parameters such as temperature and concentration of the tank liquid. Maintaining the stability of the tank liquid process parameters helps to ensure the consistency and reliability of diamond wire surface treatment and improve product quality.

[0024] The system is equipped with additive storage tanks corresponding to different process flows, and a peristaltic pump is arranged in each storage tank. The control system can accurately control the flow of the peristaltic pump, and the operator can flexibly set the flow of the corresponding additive through the control system according to the actual process requirements. This precise flow control ensures that the additive can be added to the corresponding process flow in the best proportion, which helps to optimize the performance of the cleaning liquid and improve the effect of diamond wire surface treatment, such as enhancing the adhesion of the plating layer and improving the embedding firmness of the diamond particles.

[0025] The control system sets a replacement cycle for each additive and has the function of recording and calculating the additive addition and expired remaining time. When the additive reaches the replacement cycle, the system will automatically issue an alarm prompt to remind the operator to replace the additive in time. This function effectively avoids the problem of unstable process parameters and reduced product quality caused by the use of expired additives, ensures the reliability of the production process and the consistency of product quality, and reduces the production risks and cost losses caused by poor management of additives.

[0026] The liquid storage structure of the system includes a plurality of liquid storage tanks corresponding to the process flow of each station of the diamond wire production line, which comprehensively covers various links such as pretreatment, pre-plating, sanding, thickening, and washing. For example, the pretreatment process is provided with an alkali washing tank and an acid washing tank, the pre-plating process has a pre-plating tank, and the sanding process is equipped with a post-sanding spraying tank. The reasonable arrangement of these liquid storage tanks ensures that appropriate cleaning liquid can be supplied for different process flows, meeting the diversified surface treatment needs in the diamond wire production process. The cleaning liquid at different process stages can be independently stored and supplemented, avoiding mutual interference and improving production efficiency and product quality.

[0027] The system uses a pneumatic valve as the control valve, which has the advantages of fast response speed and high control precision, and can better cooperate with the control system to realize rapid and accurate replenishment of the cleaning liquid. At the same time, a manual control valve is provided on the liquid delivery pipe corresponding to the liquid storage tank, and the operator can manually control the opening and closing of the cleaning liquid into the liquid storage tank according to the actual situation. This combination of manual and automatic control increases the flexibility of the system, facilitating emergency treatment and equipment debugging by the operator in special situations, and ensuring the smooth progress of the production process.

DETAILED DESCRIPTION

[0030] In order to deepen the understanding of the present application, the present application will be further described in conjunction with the embodiments and drawings, which are only used to explain the present application and do not constitute a limitation on the protection scope of the present application.

[0031] Implementation example:

[0032] A diamond wire surface treatment system with automatic replenishment function is arranged along a production line for manufacturing diamond wire. A liquid supply end 2 is in communication with a pure water pipe network for production. Pure water is delivered to a liquid storage structure through a liquid delivery pipe 3. The liquid storage structure is provided with liquid storage tanks corresponding to each process flow section. An additive liquid storage tank corresponding to each liquid storage tank is used to replenish the adjusting agent in the corresponding liquid storage tank. A control system controls the operation of a control valve 4 and a peristaltic pump 13 based on real-time feedback information from a liquid level collection device 5 in the liquid storage tank.

[0033] The diamond wire production sequentially passes through the processes of pretreatment, pre-plating, sanding, thickening, and washing, to achieve sanding and fixing on the surface of the bus bar. In this embodiment, the bus bar is made of tungsten wire. The bus bar surface is sequentially subjected to alkali washing, water washing, and acid washing. The tungsten wire bus bar sequentially passes through an alkali washing tank 111, an alkali post-hot water washing tank 112, an alkali post-cold water washing tank 113, an acid washing tank 114, an acid post-first cold water washing tank 115, and an acid post-second cold water washing tank 116. The alkali washing removes organic impurities such as oil stains and grease on the surface of the bus bar by saponification reaction of the tungsten wire in the alkali washing tank 111 with an alkaline solution. After alkali washing, the bus bar sequentially passes through the alkali post-hot water washing tank 112 and the alkali post-cold water washing tank 113, and is washed with clean water to flush away the residual alkaline solution and the falling impurities on the surface of the bus bar. The acid washing removes rust and oxidation layer on the surface of the bus bar by chemical reaction of the bus bar with an acidic solution in the acid washing tank 114, so that the pure metal matrix is exposed on the surface of the bus bar, and the adhesion between the bus bar and the subsequent plating layer is improved. Finally, the bus bar sequentially passes through the acid post-first cold water washing tank 115 and the acid post-second cold water washing tank 116 for water washing again to completely remove the residual acid solution and reaction products on the surface of the bus bar.

[0034] In the pre-plating process, the bus bar surface is plated with a nickel plating layer in a pre-plating tank 117, and then the residual plating solution is removed in a pre-plating post-spraying tank 118. The sanding process realizes the attachment of diamond particles on the surface of the bus bar. After completion, the residual plating solution and particle impurities are removed in a sanding post-spraying tank 119. The thickening process realizes the increase of the thickness of the bus bar plating layer in a thickening tank 1110, to further improve the bonding strength between the diamond particles and the bus bar. Finally, the bus bar sequentially passes through a spraying tank 1111, a first hot water washing tank 1112, a cold water washing tank 1113, and a second hot water washing tank 1114 for multi-stage water washing to complete the final cleaning of the surface of the bus bar.

[0035] The control system is connected to the liquid level acquisition device 5 in each storage tank to collect liquid level information in real time. In this embodiment, the control system uses a touch screen input method to set parameters, including the replenishment level and the stop replenishment level. When the liquid level is lower than the replenishment level, the corresponding control valve is opened to replenish the corresponding storage tank. When the liquid level in the storage tank is higher than the stop replenishment level, the corresponding control valve is closed. In this embodiment, the control valve is a pneumatic valve, and the opening and closing of the pneumatic valve is achieved by controlling the solenoid valve through a PLC. The control system can also set the replenishment cycle. If the liquid level is lower than the replenishment level within one replenishment cycle after the start of replenishment, the control system automatically increases the replenishment time of the next cycle; conversely, it decreases the replenishment time. By using multiple small replenishments and automatic adjustment of the replenishment amount, the replenishment amount can be precisely controlled without affecting key process parameters such as the temperature and concentration of the tank solution.

[0036] The additive storage tanks are connected to the pre-plating acid tank 121, the dividing agent storage tank 122, the sandblasting acid tank 123, the brightener storage tank 124, and the thickening acid tank 125, respectively, to store additives used in the pre-plating, sandblasting, and thickening processes. The control system automatically replenishes additives to each storage tank by operating a peristaltic pump. The control system can set the flow rate of the peristaltic pump to control the additive flow rate, corresponding to the additive replacement cycle. It records and calculates the amount of additive added and the remaining time before expiration, and issues an alarm when the replacement cycle is reached.

[0037] In this embodiment, the manual control valve 6 installed on the infusion tube 3 is a ball valve, which manually controls the opening and closing of the infusion tube 3 to achieve active fluid replenishment. In special circumstances, the manual control valve can be used as an emergency measure to cut off or open the fluid supply of the infusion tube.

[0038] Traditional systems lack real-time liquid level detection, requiring manual inspection and often resulting in untimely and inaccurate replenishment. This application's system employs closed-loop control, utilizing a liquid level acquisition device to monitor the liquid level in the storage tank in real time and feeding it back to the control system. The control system precisely adjusts the control valves according to preset replenishment and stop-replenishment levels, achieving automatic replenishment of the cleaning solution. This prevents overflow due to excessively high levels or impacts cleaning effectiveness due to excessively low levels, ensuring production stability. Through precise liquid level control and additive addition, this application ensures stable process parameters such as the concentration and temperature of the cleaning solution in each process flow, resulting in a more uniform and stable surface treatment effect on the diamond wire, improving the adhesion between the coating and the mother wire, and enhancing the adhesion of diamond particles. Existing production systems involve numerous manual operations, leading to low efficiency and a high risk of errors. This application achieves automatic replenishment of the cleaning solution and additives, reducing the workload of manual inspection and replenishment, and lowering labor costs. Simultaneously, automated operation eliminates the time differences associated with manual operations, making the production process more continuous and efficient.

In addition, under the guidance of the utility model, these features and embodiments can be modified to adapt to specific conditions and materials without departing from the spirit and scope of the utility model.
