Abstract
Description
Technical Field

[0002] With the development of the photovoltaic industry, the requirements for photovoltaic slicing technology are becoming increasingly stringent. In prior art, diamond wire is typically placed on a main roller to slice silicon. This typically requires machining grooves in the main roller, where the diamond wire is wound around the grooves to complete the wiring. In existing technology, the grooves are typically machined into the coating of the main roller.
[0003] However, in the prior art, the coating layer of the main roller is usually made of polyurethane resin material, and the hardness of polyurethane resin is relatively low at room temperature. When a tool is used to process the groove on the coating layer of the main roller, the coating layer is easily deformed, and multiple processing with the tool is required. Figure 1 As shown, the tool can be fed three times. The first feed is 0.08-0.14mm for the first groove; the second feed is 0.16-0.28mm for the second groove; and the third feed is 0.16-0.28mm for repairing the groove shape. The tool needs to feed three times to carve a groove, and the processing time of a groove is about 7 seconds. In the existing technology, the processing time of the groove is long and the processing efficiency is low.

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0043] One of the core concepts of the embodiment of the present invention is to provide a groove engraving device, such as Figure 2 As shown, a structural schematic diagram of a tool of the present invention for carving grooves on a workpiece to be processed is shown. Specifically, the grooving equipment includes: a processing chamber for accommodating the workpiece 2 to be processed, a tool 1 for carving grooves on the workpiece 2 to be processed, a clamping mechanism for clamping the workpiece 2 to be processed, and a driving mechanism for driving the clamping mechanism to rotate, wherein the clamping mechanism and the tool 1 are both arranged in the processing chamber, and the clamping mechanism can rotate relative to the processing chamber; the grooving equipment also includes: a temperature control device for controlling the temperature in the processing chamber to be within a preset temperature range, and the temperature control device is arranged in the processing chamber.
[0044] In an embodiment of the present invention, a clamping mechanism for clamping a workpiece 2 to be processed and a tool 1 for cutting a groove in the workpiece 2 are both located within a processing chamber. When the tool 1 is cutting a groove in the workpiece 2, a temperature control device can control the temperature in the processing chamber to be within a preset temperature range, so that the ambient temperature of the workpiece 2 to be processed is within the preset temperature range. Since the hardness of the workpiece 2 to be processed is relatively high within the preset temperature range, it is easier for the tool 1 to cut the groove in the workpiece 2, which can avoid residual chips in the groove and improve the cutting effect. Moreover, the driving mechanism can drive the workpiece 2 to be processed to rotate via the clamping mechanism, so that the groove of the workpiece 2 to be processed can be formed in one step, which can improve the processing efficiency and processing quality of the groove cutting of the workpiece 2 to be processed.
[0045] The processing chamber in this embodiment of the present invention is used to house and connect the clamping mechanism, the tool 1, and the temperature control device, and can be the main body of the grooving equipment or a processing machine. In actual application, while the tool 1 is grooving a workpiece 2, the workpiece 2 can be connected to the processing chamber, and the temperature control device can control the temperature within the processing chamber to within a preset temperature range. This ensures that the workpiece 2 remains within the preset temperature range during the grooving process, maintaining a high hardness.
[0046] Specifically, the clamping mechanism can rotate relative to the processing chamber. Thus, when a workpiece 2 is placed in the processing chamber for grooving, the driving mechanism can drive the workpiece 2 to rotate via the clamping mechanism, thereby accelerating the speed at which the tool 1 carves the grooves on the workpiece 2. In actual applications, due to the high hardness of the workpiece 2, the tool 1 can complete the grooving of the workpiece 2 after only one rotation of the workpiece 2 driven by the driving mechanism via the clamping mechanism. This results in a faster grooving speed and allows the groove to be formed in one step.
[0047] The driving mechanism in the embodiment of the present invention is used to provide a power source and may include at least one of hydraulic drive, pneumatic drive, electrical drive and mechanical drive. It can be specifically configured according to actual needs and is not specifically limited in the embodiment of the present invention.
[0048] The tool 1 in the embodiment of the present invention can be a V-shaped tool or a U-shaped tool. In actual application, if the tool 1 is a V-shaped tool, it can engrave a V-shaped groove on the workpiece 2 to be processed; if the tool 1 is a U-shaped tool, it can engrave a U-shaped groove on the workpiece 2 to be processed. The tool 1 can be configured according to the groove shape actually required, and this embodiment of the present invention does not specifically limit this.
[0049] Furthermore, the structure of the tool 1 may be designed symmetrically so that the grooves on the workpiece 2 to be processed have good symmetry, which facilitates the arrangement of the diamond wire.
[0050] The preset temperature range in the embodiment of the present invention is a low temperature environment, which can be set according to actual needs and is not specifically limited in the embodiment of the present invention. Specifically, the temperature control device can control the processing chamber to always maintain a constant low temperature environment.
[0051] The clamping mechanism in the embodiment of the present invention is a mechanism for clamping and fixing the workpiece 2 to be processed. It can be a combined structure composed of a gear and a rack or a clamping claw structure. It can be specifically configured according to actual needs, and the embodiment of the present invention does not make specific limitations on this.
[0052] Furthermore, the workpiece 2 to be processed can be a main roller or an auxiliary roller, etc., which is not specifically limited in the embodiment of the present invention. In actual applications, the main roller generally includes: a main roller body and a coating layer covering the main roller body. The coating layer can be made of a material with high hardness in a low temperature environment, such as polyurethane resin or polytetrafluoroethylene.
[0053] For example, the following description is made by taking the example of tool 1 carving a groove on the main roller:
[0054] Step 1: Install the main roller on the clamping mechanism in the processing cabin;
[0055] Step 2: Use a temperature control device to adjust the temperature in the processing chamber to a preset temperature range;
[0056] Step 3: Adjust the cutter 1 to be opposite to at least a portion of the main roller;
[0057] Step 4: Adjust the feed of tool 1 to insert into the coating layer of the main roller;
[0058] Step 5: The driving mechanism drives the main roller to rotate one circle through the clamping mechanism, and the tool 1 carves a groove on the coating layer of the main roller;
[0059] Step 6: Adjust the tool 1 to retract and complete the groove on the main roller;
[0060] Step 7: Adjust the tool 1 to be opposite to the other parts on the main roller, and repeat the above steps 1 to 6 to make the next groove.
[0061] like Figure 2 As shown, the tool 1 can complete the grooving with one feed, and the time for the tool 1 to complete one grooving is about 3.5 seconds. Compared with the grooving method in the prior art, it can save half the time and double the processing efficiency.
[0062] By engraving grooves on the main roller in the above-mentioned manner, the engraving time of the main roller is shortened, chips are less likely to remain between the grooves, and the groove forming effect is better. In this way, in practical applications, it is convenient to arrange the diamond wire in the groove of the main roller, which can avoid diamond wire jump and improve the slicing efficiency and slicing quality of the diamond wire.
[0063] Optionally, the preset temperature range is -10 degrees Celsius to -4 degrees Celsius. In practical applications, the hardness of the workpiece 2 is higher when it is in the temperature range of -10 degrees Celsius to -4 degrees Celsius, which can avoid residual chips in the groove, resulting in better grooving effect and higher grooving efficiency.
[0064] Specifically, at temperatures below -10°C, the polyurethane resin coating on the main roller is affected by the low temperature and shrinks significantly. After groove engraving, the groove shape and dimensions can change significantly after returning to room temperature, affecting the placement of the diamond wires and hindering slicing. At temperatures above -4°C, the polyurethane resin coating on the main roller has a lower hardness, which can easily leave polyurethane resin residue in the grooves and cause the main roller surface to become unclean, affecting the placement of the diamond wires. In the embodiments of the present invention, the preset temperature range is controlled between -10°C and -4°C. This not only removes the polyurethane resin residue from the grooves, improving the engraving effect, but also prevents significant changes in the groove shape after returning to room temperature.
[0065] In an optional embodiment of the present invention, the temperature control device may include: a temperature sensor for detecting the temperature in the processing chamber, a refrigeration mechanism for adjusting the temperature in the processing chamber, and a controller for controlling the operation of the refrigeration mechanism; the temperature sensor, refrigeration mechanism and controller are all arranged in the processing chamber, and the temperature sensor and refrigeration mechanism are electrically connected to the controller respectively.
[0066] In an embodiment of the present invention, the temperature sensor can detect the temperature inside the processing chamber and send the detected temperature value to the controller. After receiving the temperature value, the controller controls the operation of the refrigeration mechanism to facilitate the temperature control device to control the temperature inside the processing chamber within a preset temperature range.
[0067] Specifically, a temperature sensor is a sensor that senses temperature and converts it into a usable output signal. Temperature sensors are the core component of temperature measuring instruments and come in a wide variety. Temperature sensors can be categorized by their measurement method: contact and non-contact. They can also be divided into RTDs and thermocouples based on the sensor material and electronic component characteristics. The present invention does not specifically limit the type of temperature sensor; the type can be selected based on actual needs.
[0068] Specifically, a controller is a device that controls the starting, speed regulation, braking, and reversing of a motor by changing the wiring of the main or control circuits and the resistance values in a predetermined sequence. It consists of a program counter, an instruction register, an instruction decoder, a timing generator, and an operation controller. It is the "decision-making body" that issues commands, coordinating and directing the operations of the entire computer system. Controllers can be categorized as combinational logic controllers or microprogram controllers. The present invention does not specify the type of controller; specific configurations can be tailored to actual needs.
[0069] For example, the temperature sensor detects that the temperature of the processing chamber is 0 degrees Celsius, and sends information that the temperature value is 0 degrees Celsius to the controller. The controller determines that the current temperature value is higher than minus 4 degrees Celsius, and the controller adjusts the refrigeration mechanism to turn on refrigeration or increase refrigeration so that the current temperature value is within the temperature range of minus 10 degrees Celsius to minus 4 degrees Celsius.
[0070] Alternatively, the temperature sensor detects that the temperature of the processing chamber is minus 5 degrees Celsius and sends the information that the temperature value is minus 5 degrees Celsius to the controller. The controller determines that the current temperature value is within the temperature range of minus 10 degrees Celsius to minus 4 degrees Celsius, and the controller controls the refrigeration mechanism to maintain the current operating state.
[0071] Optionally, the cooling mechanism may include at least one of a heat exchanger and an air conditioner. In practical applications, the heat exchanger may adjust the temperature within the processing chamber to a range of -10°C to -4°C through heat exchange; the air conditioner may adjust the temperature within the processing chamber to a range of -10°C to -4°C through forced cooling.
[0072] Specifically, a heat exchanger (also known as a heat exchanger or heat exchange equipment) is a device used to transfer heat from a hot fluid to a cold fluid to meet the specified process requirements. It is an industrial application of convective heat transfer and heat conduction. Heat exchangers can be classified in different ways. According to their operating process, they can be divided into three categories: partition type, hybrid type, and heat storage type (or heat recovery type); according to the compactness of their surface, they can be divided into compact and non-compact types. The embodiment of the present invention does not specifically limit the type of heat exchanger, and it can be set according to actual needs.
[0073] Specifically, a room air conditioner (or room air conditioner) processes air temperature, humidity, purity, and airflow velocity to meet production and living needs. It is referred to as an "air conditioner." An air conditioner is a unit used to provide temperature control for air within a (generally enclosed) space. Its function is to regulate parameters such as the temperature, humidity, cleanliness, and airflow velocity of the air within the room (or enclosed space or area) to meet process requirements. The embodiments of the present invention do not specifically limit the type of air conditioner; the air conditioner can be configured based on actual needs.
[0074] In another optional embodiment of the invention, the grooving device may further include: a cooling device for cooling the workpiece 2 to be processed, the cooling device is arranged in the processing chamber, and the cooling device is arranged corresponding to the tool 1.
[0075] In an embodiment of the present invention, when the tool 1 is grooved on the workpiece 2 to be processed, the cooling device can be used to cool the workpiece 2 to be processed, which can further ensure that the workpiece 2 to be processed is within a preset temperature range, thereby improving the groove carving effect and efficiency of the workpiece 2 to be processed.
[0076] In actual application, the tool 1 can be used to groove the processing area of the workpiece 2 to be processed, and the cooling device can be opposite to the processing area of the workpiece 2 to be processed. The cooling device can be used to cool the processing area of the workpiece 2 to be processed to ensure the hardness of the processing area of the workpiece 2 to be processed and improve the grooving effect of the processing area of the workpiece 2 to be processed.
[0077] Optionally, the cooling device may be a coolant spraying mechanism. In practical applications, the coolant spraying mechanism can cool the workpiece 2 in real time, ensuring that the workpiece 2 is always within a preset temperature range during the grooving process.
[0078] Specifically, the coolant spraying mechanism can automatically spray coolant toward the processing area of the workpiece 2 to be processed, so that the coolant can not only cool the processing area of the workpiece 2 to be processed, but also flush away the chips in the processing area of the workpiece 2 to be processed.
[0079] Furthermore, the coolant can be an industrial liquid used to cool and lubricate the tool 1 and the workpiece 2 to be processed. It can be scientifically compounded from a variety of super-functional additives, and at the same time have good cooling performance, lubrication performance, rust prevention performance, oil removal and cleaning function, anti-corrosion function, easy dilution and other characteristics. Specifically, it can include at least one of an emulsion, a semi-synthetic cutting fluid and a fully synthetic cutting fluid. The coolant can also be an antifreeze or dry ice, which can be specifically set according to actual needs. The embodiment of the present invention does not make specific limitations on this.
[0080] In another optional embodiment of the present invention, the grooving device may further include: a heat-insulating cover 3 for keeping the workpiece 2 warm, and the heat-insulating cover 3 may be arranged in the processing cabin.
[0081] In the embodiment of the present invention, the heat-insulating cover 3 can cover the workpiece 2 to lock in the temperature, thereby better controlling the workpiece 2 to be processed to remain within a preset temperature range.
[0082] Specifically, the heat-insulating cover 3 may be an arc-shaped structure or a prismatic structure, and may be configured according to actual needs, which is not specifically limited in the embodiment of the present invention.
[0083] like Figure 3 As shown, the heat-insulating cover 3 can cover the outside of the workpiece 2 to be processed. For specific settings, please refer to the following, and the embodiment of the present invention does not make any specific limitations on this.
[0084] like Figure 3As shown, the heat-insulating cover 3 may be provided with an opening 31 , and the opening 31 may be used for passing the tool 1 so as to make the tool 1 abut against at least a portion of the workpiece 2 to be processed.
[0085] In the embodiment of the present invention, the opening 31 of the heat-insulating cover 3 may be opposite to the tool 1 , so that the tool 1 may pass through the opening 31 and contact the workpiece 2 to complete the grooving on the workpiece 2 .
[0086] like Figure 4 As shown, the heat-insulating cover 3 may include: a first cover body 32 and a second cover body 33, and the first cover body 32 and the second cover body 33 are rotatably connected.
[0087] In the embodiment of the present invention, the first cover body 32 and the second cover body 33 of the heat preservation cover 3 are rotatably connected, which is convenient for adjusting the size of the opening 31 of the heat preservation cover 3, and further convenient for covering the outside of the workpiece 2 to be processed to keep the workpiece 2 warm.
[0088] Specifically, the first cover 32 and the second cover 33 can be rotatably connected by a connecting member 34, and the connecting member 34 can be a bolt structure or a hinge structure, such as Figure 5 As shown, a case where the connecting member 34 is a hinge structure is shown. Other cases may refer to the settings, and the embodiment of the present invention does not make specific limitations on this.
[0089] Furthermore, a hinge, also known as a hinge leaf, is formally called a hinge. It often folds in two and is a component that connects two parts of an object and enables them to move. Hinge types may include plastic-sprayed washer hinges, plastic-sprayed nylon hinges, imitation copper washer hinges, imitation silver washer hinges, etc., and are not specifically limited in the present embodiment.
[0090] In actual application, the first cover body 32 and the second cover body 33 can be detachably connected. The first cover body 32 and the second cover body 33 of the thermal insulation cover 3 can be first covered on the outside of the workpiece 2 to be processed, and then the first cover body 32 and the second cover body 33 can be fastened using fasteners, so that the thermal insulation cover 3 can cover the workpiece 2 to be processed and lock in the temperature.
[0091] Optionally, the heat-insulating cover 3 may further include: an inner wall 35 and an outer wall 36 , wherein a hollow cavity is formed between the outer wall 36 and the inner wall 35 , and a coolant for cooling the workpiece 2 to be processed is provided in the hollow cavity.
[0092] In the embodiment of the present invention, a refrigerant is provided in the hollow cavity of the heat-insulating cover 3 and the workpiece 2 is cooled by the refrigerant, which can further ensure that the workpiece 2 is always within a preset temperature range during the grooving process.
[0093] Specifically, the coolant can automatically spray coolant toward the processing area of the workpiece 2 to be processed, so that the coolant can not only cool the processing area of the workpiece 2 to be processed, but also flush away the chips in the processing area of the workpiece 2 to be processed.
[0094] Furthermore, the refrigerant is an industrial liquid used to cool and lubricate the tool 1 and the workpiece 2. It can be a combination of multiple highly functional additives, exhibiting excellent cooling, lubrication, rust prevention, oil removal and cleaning, corrosion resistance, and ease of dilution. Specifically, it can include at least one of an emulsion, a semi-synthetic cutting fluid, and a fully synthetic cutting fluid. The coolant can also be antifreeze or dry ice, depending on actual needs and is not specifically limited in this embodiment of the present invention.
[0095] The groove engraving device provided by the embodiment of the present invention has at least the following advantages:
[0096] In an embodiment of the present invention, a clamping mechanism for clamping a workpiece and a tool for cutting grooves in the workpiece are both located within a processing chamber. While the tool is cutting grooves in the workpiece, a temperature control device can control the temperature within the processing chamber to remain within a preset temperature range, thereby ensuring that the ambient temperature of the workpiece is within the preset temperature range. Because the workpiece has a higher hardness within the preset temperature range, the tool facilitates cutting grooves in the workpiece, preventing residual chips in the grooves and improving the cutting effect. Furthermore, a drive mechanism can drive the workpiece to rotate via the clamping mechanism, allowing the grooves in the workpiece to be formed in one step, thereby improving the efficiency and quality of cutting grooves in the workpiece.
[0097] Reference Figure 6 , shows a flow chart of the steps of a groove engraving method according to an embodiment of the present invention.
[0098] The groove engraving method provided in the embodiment of the present invention may specifically include the following steps:
[0099] Step 101: Clamp the workpiece to be processed using a clamping mechanism that rotates relative to the processing chamber.
[0100] The processing cabin may be a main body of a grooving device or a processing machine tool, and the clamping mechanism and the workpiece to be processed may be arranged in the processing cabin.
[0101] The clamping mechanism may be a mechanism for clamping and fixing the workpiece to be processed, and the clamping mechanism may drive the workpiece to be processed to rotate. The clamping mechanism may be a combination structure consisting of a gear and a rack, or a clamping claw structure, and may be configured according to actual needs, and is not specifically limited in the embodiments of the present invention.
[0102] The workpiece to be processed may be a main roller or an auxiliary roller, etc., and this is not specifically limited in the embodiments of the present invention. In practical applications, the main roller generally includes: a main roller body and a coating layer covering the main roller body. The coating layer may be made of a material with high hardness in a low temperature environment, such as polyurethane resin or polytetrafluoroethylene.
[0103] Step 102: Using a temperature control device to control the temperature in the processing chamber to be within a preset temperature range.
[0104] The temperature control device can control the temperature in the processing chamber to be within a preset temperature range, so that the workpiece to be processed can always be in an environment within the preset temperature range and maintain a high hardness.
[0105] The preset temperature range may be a low temperature environment, in which the workpiece has a higher hardness. The preset temperature range may be set according to actual application, and the embodiment of the present invention does not specifically limit this.
[0106] Step 103: Using a driving mechanism to drive the workpiece on the clamping mechanism to rotate, so that the tool carves a groove on the workpiece.
[0107] The driving mechanism is used to provide a power source and may include at least one of hydraulic drive, pneumatic drive, electrical drive and mechanical drive. The specific configuration may be based on actual needs and is not specifically limited in the embodiments of the present invention.
[0108] The tool may be a V-shaped tool or a U-shaped tool. In practical applications, if the tool is a V-shaped tool, a V-shaped groove may be carved on the workpiece; if the tool is a U-shaped tool, a U-shaped groove may be carved on the workpiece. The tool may be configured according to the groove shape required, and this is not specifically limited in the embodiments of the present invention.
[0109] Furthermore, the structure of the tool may be designed symmetrically so that the grooves on the workpiece to be processed are symmetrical, which facilitates the arrangement of the diamond wire.
[0110] In an embodiment of the present invention, the clamping mechanism for clamping the workpiece to be processed and the tool for cutting grooves on the workpiece to be processed are both located within the processing chamber. The temperature control device can control the temperature within the processing chamber to be within a preset temperature range, so that during the process of the tool cutting grooves on the workpiece to be processed, the workpiece to be processed can always be kept in an environment within the preset temperature range, maintaining a high hardness, facilitating the tool to cut grooves on the workpiece to be processed, avoiding residual chips in the grooves, and improving the cutting effect. Furthermore, the driving mechanism can drive the workpiece to be processed to rotate via the clamping mechanism, so that the grooves on the workpiece to be processed can be formed in one step, thereby improving the processing efficiency and quality of cutting grooves on the workpiece to be processed.
[0111] Reference Figure 7 , shows a flowchart of the steps of a groove engraving method according to another embodiment of the present invention. Specifically, it may include:
[0112] Step 201: Clamp the workpiece to be processed using a clamping mechanism that rotates relative to the processing chamber.
[0113] Step 201 may refer to step 101 and will not be described in detail here.
[0114] Step 202: Use a temperature sensor to detect the temperature in the processing chamber.
[0115] The temperature sensor is arranged in the processing chamber and can detect the temperature value in the processing chamber in real time.
[0116] Specifically, a temperature sensor is a sensor that senses temperature and converts it into a usable output signal. Temperature sensors are the core component of temperature measuring instruments and come in a wide variety. Temperature sensors can be categorized by their measurement method: contact and non-contact. They can also be divided into RTDs and thermocouples based on the sensor material and electronic component characteristics. The present invention does not specifically limit the type of temperature sensor; the type can be selected based on actual needs.
[0117] Step 203: When the temperature is not within the preset temperature range, control the refrigeration mechanism to adjust the temperature in the processing chamber to the preset temperature range.
[0118] The preset temperature range may be -10°C to -4°C, and the workpiece to be processed has a higher hardness within the temperature range of -10°C to -4°C. When the temperature is lower than -10°C or higher than -4°C, the refrigeration mechanism is controlled to adjust the temperature within the processing chamber so that the temperature within the processing chamber remains within the preset temperature range.
[0119] Wherein, the refrigeration mechanism may include: at least one of a heat exchanger and an air conditioning regulator. Specifically, the heat exchanger can adjust the temperature in the processing chamber by heat exchange. A heat exchanger (also called a heat exchanger or heat exchange equipment) is a device used to transfer heat from a hot fluid to a cold fluid to meet the specified process requirements. It is an industrial application of convective heat transfer and heat conduction. Heat exchangers can be classified in different ways. According to their operating process, they can be divided into three categories: partition type, hybrid type, and heat storage type (or heat recovery type); according to the compactness of their surface, they can be divided into compact type and non-compact type.
[0120] Specifically, the air conditioner can adjust the temperature in the processing cabin by forced cooling. The air conditioner (room air conditioner) processes the temperature, humidity, purity, and air flow rate of the air to meet the needs of production and life, and is referred to as "air conditioner" for short. The air conditioner is a unit used to provide a space area (generally closed) with a device for processing air temperature changes. Its function is to adjust the parameters such as the temperature, humidity, cleanliness and air flow rate of the air in the room (or closed space, area) to meet the requirements of the process. The embodiment of the present invention does not specifically limit the type of air conditioner, and it can be set according to actual needs.
[0121] Step 204: Control the tool feed, wherein the tool feed depth is 0.16-0.28 mm.
[0122] Before the tool is fed, the tool may be adjusted to at least partially face the workpiece, and then the tool is controlled to feed so that the tool is inserted into the workpiece.
[0123] Specifically, the tool may be fed only once, and the depth of the tool fed once may be 0.16-0.28 mm (millimeter). In this way, the depth of the groove engraved by the tool on the workpiece to be processed may reach 0.16-0.28 mm.
[0124] Specifically, the tool only needs to make one cut to form the groove on the workpiece in one go. In actual application, the tool takes about 3.5 seconds to carve a single groove, which is half the time and twice as efficient as the existing technology.
[0125] Step 205: using a driving mechanism to drive the workpiece on the clamping mechanism to rotate relative to the processing chamber, a tool to carve a groove on the workpiece, and using a cooling device to spray coolant to the grooved position of the workpiece.
[0126] Among them, the driving mechanism is used to drive the clamping mechanism to rotate, and the driving mechanism is used to provide a power source, which can include at least one of hydraulic drive, pneumatic drive, electrical drive and mechanical drive. It can be specifically set according to actual needs, and the embodiment of the present invention does not make specific limitations on this.
[0127] The clamping mechanism is used to clamp the workpiece to be processed. When the driving mechanism drives the clamping mechanism to rotate, the clamping mechanism can drive the workpiece to be processed to rotate relative to the processing chamber.
[0128] Specifically, while the workpiece to be processed rotates relative to the processing chamber, the tool can be fixed relative to the processing chamber, and the tool can cut a groove on the workpiece to be processed.
[0129] Furthermore, when the tool is carving a groove on the workpiece, the cooling device can be used to spray coolant onto the grooved position of the workpiece to be machined to reduce the temperature of the grooved position of the workpiece to be machined and ensure the hardness of the workpiece to be machined.
[0130] The cooling device can cool the workpiece in real time to ensure that the workpiece is always within a preset temperature range during the grooving process. The cooling device can be a coolant spraying mechanism.
[0131] Specifically, the coolant spraying mechanism can automatically spray coolant toward the grooved position of the workpiece to be processed, so that the coolant can not only cool the grooved position of the workpiece to be processed, but also flush away the chips at the grooved position of the workpiece to be processed.
[0132] Step 206: Control the tool to retract.
[0133] Specifically, after the groove is completed, the driving mechanism is controlled to stop working, and the tool is controlled to retract.
[0134] In an embodiment of the present invention, the clamping mechanism for clamping the workpiece to be processed and the tool for cutting grooves on the workpiece to be processed are both located within the processing chamber. The temperature control device can control the temperature within the processing chamber to be within a preset temperature range, so that during the process of the tool cutting grooves on the workpiece to be processed, the workpiece to be processed can always be kept in an environment within the preset temperature range, maintaining a high hardness, facilitating the tool to cut grooves on the workpiece to be processed, avoiding residual chips in the grooves, and improving the cutting effect. Furthermore, the driving mechanism can drive the workpiece to be processed to rotate via the clamping mechanism, so that the grooves on the workpiece to be processed can be formed in one step, thereby improving the processing efficiency and quality of cutting grooves on the workpiece to be processed.
