Description

Technical Field

[0001] The present invention relates to the technical field of semiconductor manufacturing, and in particular to a processing method and a jig for single-wire cutting equipment. Background Art

[0002] At present, with the rapid development of the chip industry, the semiconductor-related equipment industry has also developed rapidly. Wire cutting equipment has the advantages of good flatness and low loss, and is deeply favored by the market. Quartz materials are widely used in semiconductor, photovoltaic, optical fiber communication and other industries due to their excellent physical and chemical stability.

[0003] The traditional cutting method usually uses an iron square plate as the cutting platform. The quartz material is directly bonded to the iron square plate with a two-component glue. After the cutting is completed, a torch is used to bake the material for debonding. This method has significant disadvantages: first, there are safety hazards in debonding by torch baking, which may cause fire or injury to operators; second, the double-plane design of the iron square plate results in a small contact surface for the circular material, insufficient bonding strength, and the material is easy to fall off during the cutting process; finally, the material is bonded to the iron square plate and lacks a directional reference. The parallelism is difficult to adjust, which can easily cause the cutting surface to tilt, affecting the material utilization rate. Therefore, the industry urgently needs a safer, more efficient and precise cutting method to overcome the limitations of existing technologies.

[0004] For example, a Chinese patent disclosed a fixture for single-wire diamond cutting of multi-sized cylindrical chalcogenide glass and quartz containers, application number CN201621389507.1, which includes a fixture base plate, a fixed baffle and two movable baffles; wherein the fixture base plate is fixed to the workbench of the cutting machine by screws, and the fixture base plate is provided with two T-slots; the fixed baffle is fixed to the fixture base plate, and the two movable baffles are respectively installed on the T-slots of the fixture base plate, and the distance between the two movable baffles and the fixed baffle is continuously adjustable, and the angle formed with the fixed baffle is adjustable.

[0005] Although the above scheme has a simple and reliable fixture structure, and can realize rapid clamping and stable cutting of cylindrical chalcogenide glass and quartz containers, simplify the process, improve process efficiency, and increase material utilization, there is still a problem that the position and angle of the material to be processed cannot be adjusted in place before processing, which may affect the processing quality. Summary of the invention

[0006] In order to overcome the problem that it is difficult to accurately adjust the position and angle of the material to be processed before clamping the current quartz fixture for single-wire cutting, the present invention provides a processing method and fixture for single-wire cutting equipment, which solves the problems of insufficient fixing strength, difficulty in releasing after fixing, and difficulty in adjusting parallelism in the traditional quartz material cutting process, thereby obtaining a higher precision, safer and more reliable cutting effect.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions: A processing jig for a single-wire cutting device comprises: a clamping jig, the clamping jig being provided with a base fixing and horizontal adjustment nuts and vertical adjustment nuts; a resin pad for bonding quartz material; a fastening pad arranged in the clamping jig; and a fastening pad nut for fixing the resin pad and the fastening pad.

[0008] The clamping fixture is the main structure. It can be fine-tuned in the horizontal plane through the base fixation and horizontal adjustment nuts, and the vertical adjustment nuts are used to adjust the height. This two-way adjustment mechanism can ensure that the quartz material maintains the best position and angle during the cutting process, effectively improving the cutting accuracy. The design of the resin pad cleverly solves the problem of damage that may be caused by direct contact between the quartz material and the metal fixture, and also provides a better bonding interface. The fastening pad and the corresponding nut further enhance the stability of the entire device to prevent vibration and displacement during the cutting process. Compared with the traditional single clamping method, this multi-level fixing scheme can better adapt to quartz materials of different shapes and sizes, and also significantly reduces the risk of dislocation or falling off of the workpiece during processing. From a mechanical point of view, the design effectively reduces local stress concentration by dispersing stress points, which is particularly important for the processing of brittle materials such as quartz. In addition, the modular design concept of the fixture leaves room for future functional expansion and optimization, such as considering integrating temperature control or vibration suppression systems to further improve processing accuracy and efficiency. Overall, the fixture design reflects a deep understanding of the processing characteristics of quartz materials, and achieves high-precision and high-stability processing requirements through sophisticated structural design.

[0009] Preferably, the resin pad has a shape with a curved surface on one side and a flat surface on the other side, which can adapt to quartz materials of different shapes. The curved surface design enables the pad to better fit irregular or curved quartz workpieces, providing a larger contact area, thereby enhancing bonding strength and stability. This design can also reduce stress concentration and reduce the risk of cracks or fragmentation of the workpiece due to uneven local force during processing. The flat design ensures good contact with the clamping fixture, which is convenient for installation and positioning. From the perspective of material mechanics, this double-sided special-shaped design can maximize the contact area with the quartz material while ensuring structural strength, thereby optimizing the transmission and distribution of force. In addition, this solution has good adaptability, can meet the processing requirements of quartz materials of different shapes and sizes, and improves the versatility and economic benefits of the fixture. From the perspective of production efficiency, this design reduces the need for frequent replacement of fixtures due to changes in the shape of the workpiece, thereby shortening the production preparation time and improving the overall production efficiency. Further, those skilled in the art can consider introducing microstructure design, such as microgrooves or specific textures, into the curved surface part to further enhance the bonding effect and reduce the generation of bubbles, thereby improving the processing quality and precision.

[0010] As a preferred method, a two-component special adhesive that can be applied to the resin pad is also included to bond the quartz material to the resin pad; the special adhesive includes a main agent and a curing agent. The main agent and the curing agent are mixed and used in a precise ratio to provide sufficient bonding strength to ensure the stability of the quartz material during the cutting process. The curing process of the two-component adhesive usually involves a chemical reaction, which can produce a stable three-dimensional polymer network, thereby providing excellent bonding performance. Compared with traditional physical adsorption or single-component adhesives, this bonding method has better heat resistance and chemical resistance, which is particularly important for quartz materials that may encounter high temperatures and chemical corrosion environments during the cutting process. In addition, another advantage of the two-component adhesive is its adjustability. By changing the ratio of the main agent and the curing agent, the curing speed and final mechanical properties of the adhesive can be adjusted to adapt to different processing environments and efficiency requirements. For example, when rapid curing is required to improve production efficiency, the proportion of the curing agent can be appropriately increased to speed up the curing reaction. In practical applications, the use of this special adhesive can also reduce the damage to the quartz material caused by improper selection of adhesives. Due to the brittleness of quartz materials, improper bonding methods may cause damage to the material during the cutting process. However, two-component special adhesive can reduce the risk of damage to quartz materials while ensuring bonding strength.

[0011] Preferably, the clamping fixture includes a fixture base, a material clamping groove and a horizontal adjustment hole, wherein the material clamping groove is used to accommodate a resin pad and a quartz material, and the horizontal adjustment hole cooperates with the base fixing and the horizontal adjustment nut to adjust the level of the quartz material on the cutting platform. The resin pad and the quartz material are accommodated in the material clamping groove, and the horizontal adjustment hole cooperates with the base fixing and the horizontal adjustment nut to achieve the horizontal adjustment of the quartz material on the cutting platform. The core advantage of this design lies in its adjustment ability and control of processing accuracy. Specifically, the design of the horizontal adjustment hole allows the position of the quartz material to be fine-tuned to ensure that it is aligned with the cutting line during the cutting process, which is crucial to improving the cutting accuracy. In the field of precision machining, even a slight position deviation may cause the product to be scrapped, so this fine-tuning mechanism has a significant impact on ensuring product quality and processing efficiency. By fine-tuning the level, it can be ensured that the quartz material is evenly supported during the cutting process, reducing material deformation or damage caused by uneven support, and helping to reduce wear during the processing process, because uniform support can reduce friction between the material and the fixture, thereby extending the service life of the fixture.

[0012] Preferably, the clamping fixture includes a vibration damping system, which includes a damper and a vibration absorbing layer, the damper is installed between the fixture base and the fastening pad, and the vibration absorbing layer is covered on the back of the resin pad. The design of this clamping auxiliary mechanism takes into account the physical properties of the quartz material and the dynamic behavior during the processing process, and provides an additional fixing method to ensure the stability of the quartz material during the cutting process, and reduce the displacement or damage of the material caused by vibration or impact force during high-speed cutting. In engineering practice, the cutting accuracy of quartz materials is extremely high, and any slight vibration may cause the unevenness of the cutting surface or the breakage of the material. Therefore, the design of the auxiliary clamping mechanism must take into account its impact on the stability of the material. According to the principle of vibration analysis, the damping characteristics of the system are crucial to the dynamic response. The existence of damping force can reduce the vibration amplitude of the system and improve the stability of the system. By adding additional contact points, the damping ratio of the system can be increased, thereby reducing vibration, which is particularly evident in underdamped or critically damped systems.

[0013] Preferably, the clamping fixture includes a temperature control module detachably connected to the resin pad, the temperature control module includes a control unit and at least one temperature sensor, and the control unit adjusts the heating or cooling element according to the set temperature parameters to control the temperature of the resin pad. In the cutting process of quartz material, the role of the temperature control module is multifaceted. First, it can optimize the bonding effect between the quartz material and the pad by controlling the temperature of the resin pad. According to the risk management and crisis response research of adhesive materials, the appropriate bonding temperature can improve the bonding strength and reduce the material loss caused by bonding failure during high-speed cutting. Secondly, precise temperature control helps to reduce the thermal stress of the quartz material during the cutting process and avoid material damage or cracking caused by local overheating. The design of the temperature control module allows the temperature of the resin pad to be adjusted at different processing stages. For example, in the early stage of cutting, a higher temperature may be required to ensure that the adhesive softens to fully achieve the bonding effect; while in the later stage of cutting, the temperature may need to be lowered to avoid thermal damage to the material and assist in the shaping of the adhesive. This modular design enables the fixture to quickly adapt to different processing requirements and improve production efficiency. Compared with the prior art method of using a fire gun for degumming and material extraction, the temperature control module of the present invention provides a safer and more controllable degumming method. Through precise temperature regulation, the material and the resin pad can be quickly separated without damaging the quartz material, greatly improving the safety and convenience of processing.

[0014] The present application also discloses a processing method for a single-wire cutting device using the above-mentioned clamping fixture, comprising the following steps: (1) installing the clamping fixture on a cutting platform via a base fixing and a horizontal adjustment nut; (2) bonding a quartz material to a resin pad; (3) installing the resin pad in the clamping fixture; (4) adjusting the horizontality and verticality of the quartz material via a vertical adjustment nut and a horizontal adjustment nut; (5) after adjustment, tightening the base fixing and the horizontal adjustment nut; (6) starting the guide wheel and the cutting wire system to perform cutting operations.

[0015] The clamping fixture is installed on the cutting platform through the base fixing and horizontal adjustment nut to ensure the basic stability of the fixture. Then, the quartz material is bonded to the resin pad by special glue. The selection of this special glue is crucial to ensure that the material does not shift during the cutting process. According to the relevant literature on diamond single-wire cutting equipment and cutting technology, constant tension control during the cutting process is very critical to ensure cutting quality. The steps of adjusting the horizontality and verticality of the quartz material by vertical adjustment nuts and horizontal adjustment nuts ensure the stability of the material during the cutting process. In addition, the steps of tightening the base fixing and horizontal adjustment nuts after adjustment further ensure the fixation of the fixture and material during the cutting process to prevent cutting errors caused by vibration or movement. The steps of starting the guide wheel and cutting line system for cutting operations involve the contact length and force state between the cutting line and the workpiece. When swing cutting, the contact length between the cutting line and the workpiece is small, and the normal pressure and tangential cutting force will be smaller, thereby reducing the risk of cutting line breakage and effectively improving the cutting surface quality.

[0016] Preferably, the base fixing and the horizontal adjustment nut and the vertical adjustment nut can jointly adjust the parallelism and horizontality of the resin pad and the quartz material on the cutting platform, so that the material maintains a suitable cutting angle and position during the cutting process. In the cutting process of quartz material, cutting accuracy is one of the key factors. Quartz material has high hardness and high brittleness, and it is easy to produce cracks and fragments during the cutting process. Therefore, the force and cutting speed must be strictly controlled during the cutting process. According to relevant literature, the cutting method research of single-wire cutting equipment mentioned that by accurately controlling cutting parameters such as cutting speed, feed rate and cutting wire tension, the cutting quality can be effectively improved and material waste can be reduced. By using the base fixing and the horizontal adjustment nut and the vertical adjustment nut in combination, the position of the quartz material on the cutting platform can be accurately adjusted to ensure the stability and accuracy of the cutting process. This precise positioning is a key factor in achieving high-quality cutting, because it directly affects the quality of the cutting surface, as well as the dimensional accuracy and surface finish of the final product.

[0017] Preferably, after the material is cut, the quartz material and the resin pad are removed as a whole and degummed and taken out through a heated water tank. After the cutting is completed, the quartz material and the resin pad are removed as a whole and degummed and taken out through a heated water tank. Compared with the traditional gun baking method, this degumming method not only improves safety, but also reduces the risk of thermal damage to the quartz material, while also improving the efficiency and controllability of the degumming process. By heating the water tank, uniform heat transfer can be achieved, and the special glue can be softened evenly, making it easier to separate the quartz material from the resin pad, reducing material damage and waste.

[0018] Preferably, the fixture includes a fixture groove, a fastening pad is arranged in the fixture groove, and the resin pad is fixed by adjusting the fastening pad nut arranged on the side of the fastening pad. The fastening pad arranged in the fixture groove fixes the resin pad by the fastening pad nut, which can provide sufficient clamping force to ensure the stability of the quartz material during the cutting process. This fixing design can minimize the material damage caused by vibration or impact force, thereby improving the cutting quality.

[0019] In addition, the design of the fastening block must also take into account its uniform compression of the resin pad to avoid uneven stress distribution during the cutting process. Uneven stress distribution may cause internal damage to the material, affecting the integrity and performance of the final product. Therefore, the fastening block can evenly distribute the force to ensure that the resin pad and quartz material remain flat and stable throughout the cutting process.

[0020] This solution has the following beneficial effects: By precisely adjusting the nuts in the horizontal and vertical directions, the correct positioning of the quartz material on the cutting platform is ensured, which improves cutting accuracy, reduces material waste and improves processing efficiency.

[0021] The resin pad is used instead of the iron square plate to increase the bonding area of ​​the quartz material, enhance the bonding strength, effectively prevent the material from shifting or falling off during the cutting process, and ensure processing safety.

[0022] The introduction of a detachable temperature control module enables precise temperature management of the resin pad, optimizes the cutting quality of quartz materials, and reduces safety hazards during degumming and material extraction.

[0023] The fixing method of the fastening pad and nut in the fixture groove is designed to improve the versatility and flexibility of the fixture, adapt to quartz materials of different shapes and sizes, reduce the number of fixture changes, and improve production efficiency.

[0024] A heated water tank can be used for degumming and material removal, avoiding the safety hazard of using a torch to bake. At the same time, it improves the degumming efficiency, reduces thermal damage to the quartz material, and improves the safety and reliability of the processing process.

DETAILED DESCRIPTION

[0030] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

[0031] Example 1 like Figure 1 , 2 As shown, the core of the single-wire cutting equipment processing jig proposed in Example 1 is to achieve the stability and accuracy of the quartz material 3 during the cutting process by combining the clamping jig 1 and the resin pad 4. The clamping jig, as the basis of the entire system, is composed of a jig base 11, a material clamping groove 9, a horizontal adjustment hole 10 and other parts. The jig base is connected to the cutting platform 5 through a base fixing and a horizontal adjustment nut 6. This connection method allows fine adjustment in the horizontal plane to ensure the parallelism between the clamping jig and the cutting platform. The material clamping groove is a key structure for accommodating the resin pad and the quartz material. Its design needs to consider quartz materials of different sizes and shapes, so the size and shape of the groove are accurately calculated. The horizontal adjustment hole cooperates with the base fixing and the horizontal adjustment nut to achieve precise adjustment in the xy plane, and theoretically can achieve micron-level adjustment accuracy. The vertical adjustment nut is responsible for the adjustment in the z-axis direction. The adjustment mechanisms in these three directions work together to ensure the precise positioning of the quartz material in three-dimensional space.

[0032] like Figure 3 , 4As shown, the processing fixture of the single-wire cutting equipment is a clamping fixture, wherein the clamping fixture is provided with a base fixing and horizontal adjustment nuts and vertical adjustment nuts; a resin pad, which is bonded to the quartz material; a fastening pad 2, which is arranged in the clamping fixture; and a fastening pad nut 8, which is used to fix the resin pad and the fastening pad 2. The clamping fixture is the main structure, and can be fine-tuned in the horizontal plane through the base fixing and the horizontal adjustment nut 6, and the vertical adjustment nut 7 is used to adjust the height. This two-way adjustment mechanism can ensure that the quartz material maintains the best position and angle during the cutting process, and effectively improves the cutting accuracy. The design of the resin pad cleverly solves the problem of damage that may be caused by direct contact between the quartz material and the metal fixture, and also provides a better bonding interface. The fastening pad 2 and the corresponding nut further enhance the stability of the entire device and prevent vibration and displacement during the cutting process. Compared with the traditional single clamping method, this multi-level fixing scheme can better adapt to quartz materials of different shapes and sizes, and also significantly reduces the risk of dislocation or falling off of the workpiece during processing. From a mechanical point of view, the design effectively reduces local stress concentration by dispersing stress points, which is particularly important for the processing of brittle materials such as quartz. In addition, the modular design concept of the fixture leaves room for future functional expansion and optimization, such as integrating temperature control or vibration suppression systems to further improve processing accuracy and efficiency. Overall, the fixture design reflects a deep understanding of the processing characteristics of quartz materials, and achieves high-precision and high-stability processing requirements through sophisticated structural design.

[0033] The resin pad is a unique design with a curved surface on one side and a flat surface on the other side, which enables it to adapt to quartz materials of different shapes. The selection of resin materials has also been carefully considered. It needs to have sufficient rigidity to prevent deformation during processing, and at the same time have a certain degree of elasticity to buffer vibration during cutting. From the perspective of material mechanics, this design can effectively disperse the cutting force, reduce stress concentration, and thus reduce the risk of material breakage. The resin pad and the quartz material are bonded using a two-component special glue. The choice of this glue is based on its high strength, low softening temperature, and corrosion resistance. From a chemical perspective, the ratio of the main agent and the curing agent directly affects the bonding strength and curing time. Epoxy resin main agents and amine curing agents are usually used. The reaction mechanism involves a ring-opening addition reaction to generate a three-dimensional network structure, thereby achieving high-strength bonding. The design purpose of the fastening pad 2 and the fastening pad 2 nut is to further enhance the stability of the resin pad in the clamping fixture. The material and shape of the fastening pad 2 need to match the resin pad to ensure uniform force. From a mechanical point of view, there is a relationship between the tightening force F of the nut of the fastening pad 2 and the friction force f: f = μF, where μ is the friction coefficient. By adjusting the tightening force, the degree of fixation of the resin pad can be accurately controlled. In order to further improve the processing accuracy and stability, the present invention also introduces a vibration damping system, including a damper and a vibration absorption layer. The damper is installed between the fixture base and the fastening pad, and its working principle is based on the energy dissipation characteristics of viscoelastic materials. When the system is vibrated, the viscoelastic material inside the damper will undergo shear deformation, converting mechanical energy into heat energy, thereby reducing the vibration amplitude. In theory, the relationship between the damping ratio ζ and the critical damping coefficient cc of the system and the actual damping coefficient c is ζ = c / (2√(km)), where k is the system stiffness and m is the mass. By adjusting the damping ratio, the system can be restored to a balanced state in the shortest time. The vibration absorption layer covers the back of the resin pad, mainly using porous materials such as polyurethane foam, and its sound absorption coefficient α varies at different frequencies, generally in the medium and high frequency bands. The best effect. This design can effectively reduce vibration transmission during the cutting process and improve processing accuracy. The introduction of the temperature control module is to solve the impact of temperature changes on materials and bonding strength during processing. The module includes a control unit and a temperature sensor, which can adjust the heating or cooling elements according to the set temperature parameters. From a thermodynamic point of view, temperature changes will affect the thermal expansion coefficient α of the material, which in turn affects the dimensional accuracy. According to the linear thermal expansion formula ΔL = αL0ΔT, where L0 is the initial length and ΔT is the temperature change, the impact of temperature changes on material size can be calculated. This impact can be minimized by precisely controlling the temperature. In practical applications, the temperature control module can use a PID (proportional-integral-differential) control algorithm to adjust the heating or cooling power in real time according to the feedback from the temperature sensor to achieve a temperature control accuracy of ±0.1°C.This precise temperature control not only helps maintain the dimensional stability of the material, but also ensures the best performance of the adhesive.

[0034] The processing method of the present invention makes full use of the characteristics of the above-mentioned fixture. First, the clamping fixture is installed on the cutting platform through the base fixing and the horizontal adjustment nut. This step requires the use of a level to ensure the initial levelness. Then, the quartz material is bonded to the resin pad. This process needs to be carried out in a clean environment to avoid dust and other impurities affecting the bonding effect. The coating thickness and uniformity of the adhesive directly affect the bonding strength, so it is possible to consider using an automatic glue coating device to ensure the consistency of the glue coating. After the resin pad is installed in the clamping fixture, it can be precisely adjusted by the vertical adjustment nut and the horizontal adjustment nut. This adjustment process can be carried out with the help of a laser rangefinder or a high-precision level, and theoretically can achieve micron-level accuracy. After the adjustment is completed, the base fixing and the horizontal adjustment nut need to be tightened. This step requires attention to torque control to avoid deformation caused by excessive tightening. Finally, the guide wheel and cutting line system are started for cutting operations. The selection of cutting lines needs to consider factors such as material hardness and cutting speed. Diamond wire is usually used, and its cutting ability is closely related to parameters such as line speed, applied pressure and coolant flow.

[0035] In this embodiment, when the single-wire cutting equipment processing jig and method of the present invention are actually applied, it is first necessary to select a suitable resin pad according to the size and shape of the quartz material to be processed. The operator should use high-precision measuring equipment, such as a three-coordinate measuring machine, to accurately measure the size of the quartz material to ensure that the selected resin pad can completely cover the surface of the material. Next, carefully clean the contact surface between the resin pad and the quartz material, and wipe it with a dust-free cloth dipped in isopropyl alcohol to ensure that the surface is free of oil and dust.

[0036] When preparing for bonding, the operator should accurately mix the main agent and curing agent of the two-component special glue in a well-ventilated environment according to the ratio provided by the manufacturer. Use a precision electronic scale to ensure the accuracy of the mixing ratio, and the error should be controlled within ±0.1g. The mixed glue should be quickly and evenly applied to the resin pad, and the application thickness should be controlled between 0.1-0.2mm. Automatic glue application equipment can be used to ensure uniformity. Before placing the quartz material on the resin pad coated with glue, the operator needs to start the temperature control module. The module includes a control unit and at least one temperature sensor, which can adjust the heating or cooling elements according to the set temperature parameters. According to the optimal curing temperature of the two-component glue used, it is usually set in the range of 25-30℃. The control unit uses a PID (proportional-integral-differential) control algorithm to adjust the heating or cooling power according to the real-time feedback of the temperature sensor to achieve a temperature control accuracy of ±0.1℃.

[0037] Place the quartz material on a temperature-controlled resin pad, taking care to avoid bubbles. A vacuum degassing device can be used to remove any tiny bubbles that may exist to improve the bonding strength. Under the action of the temperature control module, the curing process of the glue is precisely controlled. This not only speeds up the curing speed, but also ensures uniform curing of the entire bonding surface, significantly improving the bonding quality and strength. Usually, under precise temperature control conditions, the curing time can be shortened from the traditional 24 hours to 4-6 hours, greatly improving production efficiency.

[0038] After curing, the operator needs to install the clamping fixture on the cutting platform. First, use a high-precision level to check the level of the cutting platform and, if necessary, adjust the platform support feet to make corrections. Then, place the clamping fixture on the cutting platform and initially fix it with the base fixing and level adjustment nuts. Use a torque wrench to control the torque, usually in the range of 20-30 N·m. Subsequently, use a level with an accuracy of not less than 0.02mm / m to check the level of the clamping fixture and make fine adjustments by adjusting the base fixing and level adjustment nuts.

[0039] Next, carefully place the resin pad with the bonded quartz material into the material clamping slot of the clamping fixture. Wear anti-static gloves when operating. After placement, adjust the nuts vertically and horizontally for precise adjustment. Laser interferometer can be used for multi-point measurement to ensure that the overall flatness error is controlled within ±3μm. During the adjustment process, the nuts need to be adjusted slowly and evenly to avoid sudden stress changes.

[0040] After adjustment, install the fastening pad and tighten the fastening pad nut. Use a torque wrench to control the torque, usually within the range of 10-15 N·m. Tighten gradually in a cross-sequence to ensure uniform pressure distribution.

[0041] Before starting the cutting operation, carefully check the state and tension of the cutting wire. Use a dedicated wire tension measuring instrument for detection, and the tension value is usually in the range of 20-30 N. At the same time, check and adjust the flow and temperature of the cutting fluid. The flow rate of the cutting fluid is controlled at 1-2 L / min, and the temperature is maintained in the range of 20-25℃, and real-time monitoring is performed using a flow meter and temperature sensor.

[0042] During the cutting process, the temperature control module continues to work by monitoring and adjusting the temperature of the resin pad in real time to compensate for the heat generated by cutting and keep the temperature of the quartz material and the bonding interface stable. This is crucial to maintaining material dimensional stability and bonding strength, especially during long cutting operations.

[0043] Operators need to pay close attention to cutting speed and feed rate. The initial cutting speed is set to 10-15 m / s and the feed rate is controlled at 0.1-0.2 mm / min. As the cutting progresses, these parameters can be fine-tuned based on real-time monitoring data. If the cutting quality is found to be reduced or abnormal sounds are heard, the machine should be stopped immediately for inspection.

[0044] In addition, in order to further improve processing accuracy and efficiency, it is possible to consider introducing a real-time monitoring and feedback mechanism into the system. For example, a high-speed camera can be installed in the cutting area to analyze the cutting status in real time through image processing algorithms and adjust the cutting parameters in a timely manner. At the same time, acceleration sensors can be installed at key locations to monitor vibration conditions. If abnormal vibration is detected, the system can automatically adjust the cutting speed or stop the machine for inspection.

[0045] In this embodiment, a series of interchangeable resin pads and fastening pads can also be designed to adapt to quartz materials of different shapes and sizes. These interchangeable parts should be precision-processed to ensure that their dimensional accuracy and surface roughness meet the requirements. At the same time, a material database is established to record the optimal processing parameters of different materials, including cutting speed, feed rate, cutting fluid flow rate, and temperature control parameters, so as to quickly adjust and optimize the processing process.

[0046] By combining the application of the temperature control module, the single-wire cutting equipment processing fixture and method of the present invention not only improves the processing accuracy and efficiency, but also greatly enhances the stability and controllability of the process, providing a reliable technical guarantee for the processing of high-quality quartz materials.

[0047] Example 2 This embodiment adopts an improved single-wire cutting equipment processing jig and method, the core of which is to optimize the degumming and material taking process of quartz material. As in Example 1, this embodiment also uses a carefully designed clamping jig and resin pad to ensure the stability and accuracy of the quartz material during the cutting process. The basic structure of the clamping jig remains unchanged, including the jig base, the material clamping groove, the horizontal adjustment hole and other parts. The resin pad still adopts a unique design of a curved surface on one side and a flat surface on the other side to adapt to quartz materials of different shapes. However, the innovation of this embodiment lies in the processing method after the cutting is completed. When the quartz material is cut, the operator can remove the quartz material and the resin pad as a whole, and then degumming and taking the material through the heating water tank. Compared with the temperature control module used in Example 1, this method has the advantages of simpler operation and lower cost. The temperature of the heating water tank is usually controlled in the range of 60-80°C, and the specific temperature depends on the softening point of the two-component glue used. The water temperature in the water tank is precisely controlled by a constant temperature heating system, and the temperature fluctuation is controlled within ±1°C. This degumming method can not only effectively avoid the safety hazards of the traditional gun baking method, but also ensure the uniformity and controllability of the degumming process. The water heating method can evenly soften the glue layer and reduce the material stress or deformation problems that may be caused by local overheating. In addition, this method also has environmental advantages because no harmful gas emissions are generated. In general, this embodiment further improves processing efficiency and safety by optimizing the degumming and material collection process, while maintaining the advantages of high-precision processing.

[0048] In the actual application of Example 2, most of the operation procedures are the same as those of Example 1, but the processing steps after the cutting is completed are different. After the cutting operation is completed, the operator first needs to shut down the cutting system to ensure that the cutting line stops moving completely. Then, carefully loosen the nuts that tighten the pads, paying attention to torque control to avoid sudden release of stress that causes material deformation. Using anti-static gloves, remove the quartz material and the resin pad as a whole from the clamping fixture.

[0049] Next is the core step of this embodiment - degumming in a heated water tank. The operator needs to pre-set the temperature of the heated water tank, usually between 60-80°C, and the specific temperature should be determined according to the softening point of the glue used. Use a precision temperature control system, such as a PID controller, to ensure that the water temperature is stable within the set value ±1°C. Slowly immerse the entire material in the heated water tank. The immersion time is generally 15-30 minutes, and the specific time depends on the thickness of the glue layer and the size of the material.

[0050] During the immersion process, the operator needs to closely observe the softening of the adhesive layer. A dedicated temperature probe can be used to monitor the material surface temperature in real time to ensure the temperature uniformity of the entire debonding process. When the adhesive layer begins to soften, a special plastic tool can be used to gently separate the quartz material and the resin pad. Avoid using metal tools to prevent scratching the material surface.

[0051] After debonding is completed, the quartz material is immediately transferred to room temperature deionized water for cooling to prevent the material from stress due to rapid temperature changes. After cooling, the surface of the material is cleaned with a dust-free cloth dipped in isopropyl alcohol to remove residual glue. Finally, the dimensional accuracy and surface quality of the material are checked using precision measuring equipment such as a three-coordinate measuring machine.

[0052] This degumming method is not only simple to operate and low in cost, but also ensures the uniformity and controllability of the degumming process, effectively avoiding the potential safety hazards and material damage risks that may be caused by traditional methods. At the same time, since the entire process is carried out in water, the emission of harmful gases is greatly reduced, meeting environmental protection requirements. Through this optimized degumming and material collection method, the solution of this embodiment further improves production efficiency and safety while maintaining the advantages of high-precision processing.
