Description

Technical Field

[0001] This invention relates to the field of diamond grinding wheel processing technology, specifically to a diamond grinding wheel processing device. Background Technology

[0002] In the traditional application of diamond grinding wheel processing equipment, the clamping and disassembly of grinding wheels has long been a technical bottleneck. The main pain points are concentrated in the following aspects, which directly affect processing efficiency, dressing accuracy and ease of operation.

[0003] Traditional equipment often uses manual tightening of clamps (such as bolt clamping or manual adjustment with a three-jaw chuck) to fix diamond grinding wheels. This requires operators to repeatedly calibrate the wheel position, which is not only labor-intensive but also prone to wheel misalignment due to human error. This can lead to problems like "over-dressing" or "incomplete dressing" during subsequent laser dressing, making it impossible to guarantee the consistency of dressing quality for batches of grinding wheels. Some semi-automatic clamping equipment requires additional independent power sources such as air pumps and hydraulic systems to drive the clamping mechanism and fix the grinding wheel via pneumatic or hydraulic pressure. These additional power sources increase the structural complexity and manufacturing cost of the equipment.

[0004] The disassembly process is inefficient due to its multiple steps: traditional equipment requires operators to reverse the operation of multiple clamping components (such as loosening bolts, turning off the air pump / hydraulic valve, and manually prying open the clamping arms). This is cumbersome, and the movements of each component lack coordination, resulting in lengthy disassembly times for a single grinding wheel. Especially in batch processing scenarios, frequent manual disassembly significantly reduces the overall efficiency of the equipment, failing to meet the demands of high-efficiency production. Therefore, we have introduced a new diamond grinding wheel processing device. Summary of the Invention

[0005] The purpose of this invention is to provide a diamond grinding wheel processing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a diamond grinding wheel processing device, comprising a laser dressing chamber and a conveyor belt running through the laser dressing chamber, wherein mounting components for mounting diamond grinding wheels are provided at equal intervals on the conveyor belt, and an industrial robotic arm for mounting a laser gun is provided at the top of the laser dressing chamber, wherein the laser gun can be adjusted to any position through the industrial robotic arm, and the nanosecond pulse laser of the laser gun performs laser dressing on the surface of the diamond grinding wheel;

[0007] The mounting assembly includes mounting seats that are fixed at equal intervals on the conveyor belt and clamping components that are slidably disposed on the mounting seats.

[0008] The clamping assembly is provided with drive support wheel assemblies on the upper outer sides of both ends, and with centering abutment assemblies on the upper inner sides of both ends. The centering abutment assemblies are connected to a pressing positioning assembly that is movably connected to the mounting base.

[0009] When the shaft on the diamond grinding wheel is placed on the drive support wheel assembly, the clamping assembly moves downward relative to the mounting base under the gravity of the diamond grinding wheel. At the same time, the downward positioning assembly moves closer to and presses against the upper end of the shaft, and the centering abutment assembly abuts against the side of the diamond grinding wheel until the diamond grinding wheel is centered and clamped.

[0010] Preferably, the laser trimming chamber is fixed at the upper middle part of the base, and the upper sides of the base are also provided with supports for installing the conveyor belt, and the corresponding supports are also provided with a first servo motor for driving the conveyor belt to rotate.

[0011] Preferably, the two ends of the conveyor belt extend through the openings on the left and right sides of the lower part of the laser trimming chamber, and the top of the openings is provided with curtains.

[0012] Preferably, the mounting base includes a U-shaped base, with U-shaped clearance slots at the top center of both ends of the U-shaped base, and limiting rectangular slots at the center of both ends of the U-shaped base;

[0013] The clamping assembly includes a lifting slide and side limiting seats fixed at both ends of the lifting slide. The lifting slide slides into the limiting rectangular groove. A return spring is connected between the bottom of the limiting rectangular groove and the bottom of the lifting slide. The inner wall of the side limiting seat is in close contact with the outer walls of both ends of the U-shaped seat.

[0014] Preferably, the drive support wheel assembly includes two sets of drive support wheels movably connected to the outer side of the upper part of the side limiting seat, and a second servo motor fixed to the outer side of the upper part of the corresponding side limiting seat by a bracket;

[0015] The motor pulley at the output end of the second servo motor is connected to the outer pulley on the outside of the corresponding drive support wheel via an external transmission belt. The drive shaft in the middle of the inner side of the drive support wheel passes through the side limit seat and is connected to an inner pulley. An inner transmission belt connects the two sets of inner pulleys.

[0016] Preferably, the centering abutment assembly includes an inverted triangular protrusion fixed to the inner side of the upper part of the side limiting seat, a side piston disposed in the air intake chamber in the middle of the inverted triangular protrusion, a push rod fixed to the middle of the side piston, and an abutment head screwed to the inner end of the push rod after it extends out of the air intake chamber.

[0017] The cylinder is located at the lower middle of the lifting slide, and a bottom piston is installed inside the cylinder. A vertical rod is fixed at the lower middle of the bottom piston and the upper middle of the U-shaped seat.

[0018] An air guide pipe is connected between the bottom of the outer end of the air intake chamber and the top of the cylinder.

[0019] Preferably, the pressing positioning assembly includes a pressing positioning arm whose front and rear parts are symmetrically and movably connected by a pin on the inner side of the U-shaped clearance slot, a pressing roller movably connected to the top of the pressing positioning arm, and a pin rod provided at the bottom of the pressing positioning arm.

[0020] The inverted triangular protrusion has concave grooves on its front and rear walls, and oblique through grooves on both sides of the concave grooves. The bottom of the pressing positioning arm extends into the concave groove, and the pin slides into the oblique through groove.

[0021] Compared with the prior art, the beneficial effects of the present invention are: the present invention can complete the precise clamping of diamond grinding wheels without manual operation through the "gravity triggering - multi-component linkage" mechanism: when the shaft of the diamond grinding wheel is placed on the drive support wheel, the grinding wheel itself is driven by gravity to trigger the following two positioning actions simultaneously: triggering the centering and abutting component to achieve horizontal centering of the diamond grinding wheel, and triggering the pressing positioning component to achieve vertical positioning of the diamond grinding wheel.

[0022] This process relies entirely on mechanical linkage, eliminating the need for additional equipment such as air pumps. This simplifies the equipment structure, reduces manufacturing costs and maintenance requirements, and eliminates the need for manual adjustments. This reduces the labor intensity of operators, avoids manual positioning errors, ensures the consistency of clamping accuracy for each grinding wheel, and improves the quality of batch dressing.

[0023] The beneficial effects of this invention in solving the problem of "low efficiency in the disassembly process" are: elastic reset + simultaneous release of multiple constraints, realizing automatic unlocking and disassembly of diamond grinding wheels;

[0024] Through the "gravity unloading-elastic reset" mechanism, all positioning constraints are automatically released when the grinding wheel is removed: the centering abutment component resets, releasing the horizontal constraint of the diamond grinding wheel; the downward positioning component resets, releasing the vertical constraint of the diamond grinding wheel.

[0025] The entire disassembly process requires no manual operation to clamp the parts; simply removing the diamond grinding wheel completes the automatic unlocking, significantly shortening the disassembly time and improving the overall working efficiency of the equipment, making it especially suitable for batch processing scenarios.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example:

[0043] Please see Figure 1-14 The present invention provides a technical solution:

[0044] A diamond grinding wheel processing device includes a control console, a laser dressing chamber 1, and a conveyor belt 5 passing through the laser dressing chamber 1;

[0045] The laser trimming chamber 1 is fixed at the upper middle part of the base 4. The upper sides of the base 4 are also provided with supports 7 for mounting the conveyor belt 5, and the corresponding supports 7 are also provided with a first servo motor 6 for driving the conveyor belt 5 to rotate.

[0046] The conveyor belt 5 is provided with mounting components 8 for mounting diamond grinding wheels 10 at equal intervals. The top of the laser dressing chamber 1 is provided with an industrial robotic arm 2 for mounting a laser gun 3. The laser gun 3 can be adjusted to any position through the industrial robotic arm 2. The nanosecond pulse laser of the laser gun 3 performs laser dressing on the surface of the diamond grinding wheel 10.

[0047] The control panel is equipped with a touch screen display, which has a built-in PLC controller. The first servo motor 6 works under the control of the PLC controller, so that the conveyor belt 5 transports the mounting component 8 and the diamond grinding wheel 10 on the mounting component 8 into the laser dressing chamber 1.

[0048] The automated feeding and unloading of diamond grinding wheels 10 is realized, eliminating the need for manual handling of diamond grinding wheels 10 in and out of the laser dressing chamber 1. This not only reduces the labor intensity of operators but also improves the working efficiency of the equipment and reduces the interference of manual operation on the dressing process.

[0049] The first servo motor 6 features high control precision and stable speed, which can accurately control the running speed and start / stop position of the conveyor belt 5, ensuring that the installation components 8 and diamond grinding wheel 10 can be accurately delivered to the designated dressing position in the laser dressing chamber 1, avoiding the dressing effect being affected by deviations in the transportation position.

[0050] Furthermore, the industrial robotic arm 2 operates under the control of the PLC controller, causing the laser gun 3 to move to a suitable position, and then controlling the nanosecond pulse laser of the laser gun 3 to perform laser finishing on the surface of the diamond grinding wheel 10.

[0051] An industrial robotic arm 2 is mounted on the top of the laser dressing chamber 1, and a laser gun 3 is mounted on the industrial robotic arm 2. The industrial robotic arm 2 has the characteristics of multi-degree-of-freedom movement, which can drive the laser gun 3 to adjust to any position in three-dimensional space. This connection and drive method enables the laser gun 3 to adapt to the dressing needs of diamond grinding wheels 10 of different sizes and shapes, and can accurately irradiate various parts of the surface of the diamond grinding wheel 10 with laser, ensuring that all parts of the surface of the diamond grinding wheel 10 are uniformly and effectively dressed, thereby improving the overall dressing quality of the grinding wheel.

[0052] Nanosecond pulsed lasers can concentrate and release laser energy in an extremely short time. By utilizing the high peak power and controllable thermal effect of nanosecond lasers, the bonding agents (such as resin, ceramics, and metals) on the surface of the diamond grinding wheel 10 are selectively removed, and the abrasive grain morphology of the diamond grinding wheel 10 is appropriately modified. Ultimately, the sharpness, geometric accuracy, and surface morphology of the diamond grinding wheel 10 are restored, thus solving the problem of decreased processing accuracy caused by "clogging, passivation, and deformation" of the diamond grinding wheel 10 during the grinding process.

[0053] The computed tomography microstructure of the abrasive grains after the diamond grinding wheel 10 is finally formed is similar to the horny tooth tip shape of a chiton's tooth (e.g., Figure 13 (as shown), and as per the instruction manual. Figure 14As shown, the wear and stress distribution of the chiton horn-like tooth tips on the surface of the machined diamond grinding wheel indicates that both the wear and stress conditions meet the performance parameter requirements of the diamond grinding wheel. Its structural parameters are: tooth tip inclination angle of 25°, wedge angle of 45°, and clearance angle of 20°. The microstructure morphology is characterized by asymmetrical wedge-shaped protrusions, with the back surface wearing faster than the ventral surface, ensuring that the tooth tips maintain an acute angle shape during grinding and achieving the self-sharpening characteristic of the diamond grinding wheel 10 surface.

[0054] The mounting assembly 8 includes mounting seats 802 that are fixed at equal intervals on the conveyor belt 5 and clamping components 801 that are slidably disposed on the mounting seats 802.

[0055] Both ends of the conveyor belt 5 extend through the openings on the lower left and right sides of the laser dressing chamber 1, and the top of the openings is provided with curtains 9. The curtains 9 facilitate the conveyor belt 5 to transport the mounting assembly 8 and the diamond grinding wheel 10 on the mounting assembly 8 into or out of the laser dressing chamber 1.

[0056] The clamping assembly 801 has drive support wheel assemblies on the upper outer sides of both ends, and a centering abutment assembly on the upper inner sides of both ends. The centering abutment assembly is connected to a pressing positioning assembly that is movably connected to the mounting base 802.

[0057] Mounting base 802 includes a U-shaped base 8026, with U-shaped clearance slots 8025 at the top center of both ends of the U-shaped base 8026, and limiting rectangular slots 8023 at the center of both ends of the U-shaped base 8026.

[0058] The clamping assembly 801 includes a lifting slide 80101 and side limiting seats 80103 fixed at both ends of the lifting slide 80101. The lifting slide 80101 slides in the limiting rectangular groove 8023. A return spring 8024 is connected between the bottom of the limiting rectangular groove 8023 and the bottom of the lifting slide 80101. The inner wall of the side limiting seat 80103 is in close contact with the outer walls of both ends of the U-shaped seat 8026.

[0059] Because the lifting slide 80101 slides into the limiting rectangular groove 8023, and the inner wall of the side limiting seat 80103 is in close contact with the outer walls of both ends of the U-shaped seat 8026, it guides the movement direction of the lifting slide 80101, ensuring that the lifting slide 80101 can only move up and down in the vertical direction, thus avoiding horizontal deviation that could affect the clamping accuracy.

[0060] The U-shaped seat 8026 provides installation space for the clamping assembly 801. At the same time, the U-shaped structure makes it easy for operators to observe the clamping status of the diamond grinding wheel 10 from the side, and also facilitates adjustment and maintenance when clamping problems occur.

[0061] The U-shaped clearance slot 8025 is located at the top center of both ends of the U-shaped seat 8026, providing space for the inverted triangular protrusion 80109 to move up and down.

[0062] The return spring 8024 is connected between the bottom of the limiting rectangular groove 8023 and the bottom of the lifting slide 80101. When the diamond grinding wheel 10 is removed from the clamping assembly 801, the return spring 8024 can push the lifting slide 80101 upward to reset, so that the clamping assembly 801 returns to its initial state, which facilitates the clamping of the next diamond grinding wheel 10 and improves the automation and efficiency of clamping.

[0063] The drive support wheel assembly includes two sets of drive support wheels 80106 that are movably connected to the outer side of the upper part of the side limit seat 80103, and a second servo motor 80104 that is fixed to the outer side of the upper part of the side limit seat 80103 by a bracket 80108.

[0064] The motor pulley at the output end of the second servo motor 80104 is connected to the outer pulley on the outside of the corresponding drive support wheel 80106 via an outer drive belt 80105. The drive shaft in the middle of the inner side of the drive support wheel 80106 passes through the side limit seat 80103 and is connected to an inner pulley. An inner drive belt 80112 is connected between the two sets of inner pulleys.

[0065] The second servo motor 80104 is fixed to the upper outer side of the side limit seat 80103 by the bracket 80108. The motor pulley at its output end is connected to the outer pulley on the outside of the drive support wheel 80106 through the outer transmission belt 80105. This belt drive method has the function of buffering and vibration reduction, which can reduce the impact on the drive support wheel 80106 and the diamond grinding wheel 10 during motor start-up and operation.

[0066] Meanwhile, the drive shaft in the middle of the inner side of the drive support wheel 80106 is connected to the inner pulley, and the inner transmission belt 80112 is connected between the two sets of inner pulleys, realizing the synchronous rotation of the two sets of drive support wheels 80106. This ensures that the diamond grinding wheel 10 shaft 101 is subjected to uniform force, and avoids the diamond grinding wheel 10 from rotating eccentrically due to inconsistent speed of the drive support wheel 80106, which would affect the laser dressing accuracy.

[0067] In addition, the high-precision control of the second servo motor 80104 can achieve precise adjustment of the rotation speed of the diamond grinding wheel 10, meeting the requirements of different dressing processes for the rotation speed of the diamond grinding wheel 10.

[0068] The centering abutment assembly includes an inverted triangular protrusion 80109 fixed to the inner side of the upper part of the side limiting seat 80103, a side piston 80120 disposed in the air intake chamber 80121 in the middle of the inverted triangular protrusion 80109, a push rod 80116 fixed in the middle of the side piston 80120, and an abutment head 80110 screwed to the inner end of the push rod 80116 after it extends out of the air intake chamber 80121;

[0069] The inverted triangular protrusion 80109 is fixed on the upper inner side of the side limiting seat 80103. Its structural design not only provides installation space for components such as the air intake chamber 80121 and the side piston 80120, but also works in conjunction with the downward positioning component to achieve linkage, making the clamping process more compact and efficient.

[0070] The abutment head 80110 is screwed to the top rod 80116, which makes it easy to replace the abutment head 80110 with different materials and shapes according to the material and size of the diamond grinding wheel 10, thus improving the versatility of the centering abutment component.

[0071] A cylinder 80102 is provided in the middle of the lower end of the lifting slide 80101. A bottom piston 8022 is provided inside the cylinder 80102. A vertical rod 8021 is fixed in the middle of the lower end of the bottom piston 8022 and the upper end of the middle of the U-shaped seat 8026.

[0072] An air guide pipe 80115 is connected between the bottom of the outer end of the intake chamber 80121 and the top of the cylinder barrel 80102.

[0073] When the lifting slide 80101 moves downward, the cylinder 80102 moves relative to the bottom piston 8022, thereby compressing the gas inside the cylinder 80102 and providing power to the centering and supporting component. This structure eliminates the need for additional power sources such as air pumps, utilizing the weight of the diamond grinding wheel 10 to achieve power transmission, simplifying the equipment structure, reducing equipment costs, and making the clamping process more energy-efficient and environmentally friendly.

[0074] The mechanical motion of the lifting slide 80101 is converted into a change in gas pressure, which in turn drives the movement of the centering abutment component. This achieves a clever combination of mechanical motion and pneumatic transmission, making the clamping process more stable and gentle, and avoiding impact damage to the diamond grinding wheel 10 caused by rigid connection.

[0075] The pressing positioning assembly includes a pressing positioning arm 80111 symmetrically and movably connected to the front and rear of the inner side of the U-shaped clearance slot 8025 by a pin 80114, a pressing roller 80107 movably connected to the top of the pressing positioning arm 80111, and a pin 80117 set at the bottom of the pressing positioning arm 80111.

[0076] The inverted triangular protrusion 80109 has an inwardly concave inclined groove 80118 on its front and rear walls. The inwardly concave inclined groove 80118 has inclined through grooves 80119 on its two side walls. The bottom of the downwardly pressing positioning arm 80111 extends into the inwardly concave inclined groove 80118, and the pin 80117 slides into the inclined through groove 80119.

[0077] The pressing positioning arm 80111 is symmetrically and movably connected to the front and rear parts of the U-shaped clearance slot 8025 via a pin 80114. The pin 80114 provides a pivot point for the pressing positioning arm 80111, allowing the pressing positioning arm 80111 to rotate flexibly around the pin 80114, thereby achieving the pressing and releasing of the diamond grinding wheel 10 shaft 101.

[0078] The pressure roller 80107 is movably connected to the top of the pressure positioning arm 80111. When pressing the diamond grinding wheel 10 shaft 101, the pressure roller 80107 and the shaft 101 are in rolling contact, which can reduce the friction between the two and avoid wear on the shaft 101 and the pressure positioning arm 80111 during the rotation of the grinding wheel, extend the service life of the components, and also ensure the smooth rotation of the grinding wheel.

[0079] When the shaft 101 on the diamond grinding wheel 10 is placed on the drive support wheel assembly, the clamping assembly 801 moves downward relative to the mounting base 802 under the gravity of the diamond grinding wheel 10. At the same time, the pressing positioning assembly moves closer to and presses against the upper end of the shaft 101, and the centering abutment assembly abuts against the side of the diamond grinding wheel 10 until the diamond grinding wheel 10 is centered and clamped.

[0080] When removing the diamond grinding wheel 10, the mounting component 8 achieves convenient disassembly of the diamond grinding wheel 10 through a process of "gravity unloading - elastic reset - multi-component linkage release". The specific working principle is as follows:

[0081] When the operator removes the diamond grinding wheel 10 from the drive support wheel assembly, the gravity load of the diamond grinding wheel 10 is removed from the clamping assembly 801, and the return spring 8024 (originally in a compressed state) in the mounting base 802 releases its elastic potential energy, pushing the lifting slide 80101 upward along the limiting rectangular groove 8023, thereby driving the clamping assembly 801 to reset as a whole.

[0082] During the upward movement of the lifting slide 80101, the cylinder 80102 at its lower end also moves upward, generating relative movement with the vertical rod 8021 fixed on the U-shaped seat 8026 and the bottom piston 8022, causing the internal volume of the cylinder 80102 to increase and the air pressure to decrease. At this time, the air inlet chamber 80121 of the central abutment component forms an air pressure balance with the cylinder 80102 through the air guide pipe 80115. Under the action of the air pressure difference, the side piston 80120 moves outward, driving the push rod 80116 and the abutment head 80110 to move backward synchronously, releasing the abutment constraint on the side of the diamond grinding wheel 10.

[0083] Simultaneously, the upward movement of the lifting slide 80101 causes the side limiting seat 80103 and the inverted triangular protrusion 80109 to move upward. The concave groove 80118 on the front and rear walls of the inverted triangular protrusion 80109 slides relative to the pin 80117 at the bottom of the pressing positioning arm 80111. Due to the guiding effect of the inclined groove 80119, the pressing positioning arm 80111 rotates around the pin 80114, and the pressing roller 80107 at the top is lifted accordingly, releasing the clamping force on the upper end of the diamond grinding wheel 10 shaft 101.

[0084] Finally, all positioning constraints of the clamping assembly 801 are completely released, allowing the operator to easily remove the diamond grinding wheel 10. The mounting assembly 8 then returns to its initial state under the action of the return spring 8024, preparing for the next grinding wheel clamping. The entire process requires no additional operation; automatic unlocking is achieved through the linkage of the mechanical structure, ensuring convenient disassembly while avoiding damage to the grinding wheel or clamping components.

[0085] Specifically, when using it:

[0086] (a) Clamping and fixing stage of diamond grinding wheel 10:

[0087] The shaft 101 on the diamond grinding wheel 10 is first placed on the front and rear sets of drive support wheels 80106 of the drive support wheel assembly.

[0088] Under the action of the diamond grinding wheel 10's own gravity, the lifting slide 80101 in the clamping assembly 801 slides downward along the limiting rectangular groove 8023 on the mounting base 802, while compressing the return spring 8024 between the bottom of the limiting rectangular groove 8023 and the bottom of the lifting slide 80101.

[0089] When the lifting slide 80101 moves down, the bottom piston 8022 in the lower middle cylinder 80102 moves up relative to the cylinder 80102, causing the gas in the cylinder 80102 to be compressed. The compressed gas is then transported through the air guide pipe 80115 to the air intake chamber 80121 of the inverted triangular protrusion 80109 in the central abutment assembly.

[0090] The air pressure inside the air intake chamber 80121 increases, pushing the side piston 80120 to move inward. The push rod 80116 fixed in the middle of the side piston 80120 moves accordingly. The abutment head 80110 screwed to the inner end of the push rod 80116 finally abuts against the side of the diamond grinding wheel 10, achieving the horizontal centering of the diamond grinding wheel 10.

[0091] Simultaneously, the lifting slide 80101 moves downward, causing the side limiting seats 80103 at both ends of the clamping assembly 801 to move downward, and the inverted triangular protrusion 80109 fixed on the inner side of the upper part of the side limiting seat 80103 moves downward synchronously. Since the bottom of the pressing positioning arm 80111 in the pressing positioning assembly extends into the concave groove 80118 on the front and rear walls of the inverted triangular protrusion 80109, and the pin 80117 slides in the oblique through grooves 80119 on both sides of the concave groove 80118, when the inverted triangular protrusion 80109 moves downward, through the cooperation of the oblique through groove 80119 and the pin 80117, the pressing positioning arm 80111 is driven to rotate around the pin shaft 80114. The pressing roller 80107 movably connected to the top of the pressing positioning arm 80111 then approaches and presses against the upper end of the rotating shaft 101 of the diamond grinding wheel 10, completing the vertical positioning of the diamond grinding wheel 10. At this point, the diamond grinding wheel 10 is fully centered and clamped.

[0092] (II) Equipment Start-up and Diamond Grinding Wheel 10 Transportation Stage:

[0093] The operator sends work instructions through the touch screen of the control console. After receiving the instructions, the built-in PLC controller first controls the first servo motor 6 on the two supports 7 on the upper end of the base 4 to start.

[0094] The first servo motor 6 drives the conveyor belt 5 to rotate. Since the conveyor belt 5 is provided with mounting components 8 at equal intervals and the diamond grinding wheel 10 is pre-installed on the mounting components 8, the conveyor belt 5 carries the mounting components 8 and the diamond grinding wheel 10 to the laser dressing chamber 1.

[0095] The two ends of the conveyor belt 5 extend through the openings on the left and right sides of the lower part of the laser dressing chamber 1. When the mounting component 8 and the diamond grinding wheel 10 approach the opening, the curtain 9 at the top of the opening naturally opens under the drive of the conveyor belt 5 and the push of the grinding wheel, making it convenient for the mounting component 8 and the diamond grinding wheel 10 to enter the laser dressing chamber 1. After the grinding wheel enters, the curtain 9 returns to the closed state by its own elasticity, which can reduce the leakage of dust in the laser dressing chamber 1.

[0096] (III) Laser trimming stage:

[0097] The PLC controller activates the industrial robotic arm 2 located at the top of the laser dressing chamber 1. The robotic arm 2 moves the laser gun 3 according to a preset program, adjusting it to a suitable position corresponding to the surface of the diamond grinding wheel 10.

[0098] After the position adjustment is completed, the PLC controller controls the nanosecond pulse laser in the laser gun 3 to emit laser light. The nanosecond pulse laser releases laser energy in a concentrated manner in a very short time, and uses high peak power and controllable thermal effect to act on the surface of the diamond grinding wheel 10: preferentially and selectively removing the bonding agent (such as resin, ceramic, metal) on the surface of the grinding wheel, while moderately dressing the abrasive grain morphology of the diamond grinding wheel 10.

[0099] During the dressing process, if it is necessary to adjust the angle or position of the diamond grinding wheel 10 to achieve full dressing, the PLC controller can control the second servo motor 80104 of the drive support wheel assembly in the clamping assembly 801 to start. The motor pulley at the output end of the second servo motor 80104 drives the outer pulley on the outside of the drive support wheel 80106 to rotate through the outer transmission belt 80105. The drive support wheel 80106 rotates accordingly, thereby driving the rotating shaft 101 of the diamond grinding wheel 10 to rotate, thus realizing the angle adjustment of the diamond grinding wheel 10.

[0100] At the same time, the drive shaft in the middle of the inner side of the drive support wheel 80106 drives the inner pulley to rotate. The inner pulley drives the corresponding other set of drive support wheels 80106 to rotate synchronously through the inner transmission belt 80112, ensuring that the grinding wheel rotates smoothly.

[0101] After a period of laser dressing, the blockages on the surface of the diamond grinding wheel 10 are removed, and the abrasive grains regain their sharp shape (the microstructure of the abrasive grains is similar to the horny tooth tip shape of a chiton's tooth, with a forward tilt angle of 25°, a wedge angle of 45°, and a clearance angle of 20°, forming an asymmetrical wedge-shaped protrusion. The back surface wears faster than the ventral surface, which allows the tooth tip to maintain an acute angle shape during the grinding process, achieving self-sharpening characteristics). The geometric accuracy and surface morphology of the diamond grinding wheel 10 are also restored, solving the problem of decreased machining accuracy caused by blockage, dulling, and deformation of the diamond grinding wheel 10 during the grinding process.

[0102] (iv) Dressing completion and grinding wheel output stage:

[0103] After the diamond grinding wheel 10 is dressed, the PLC controller controls the nanosecond pulse laser to stop working, and at the same time controls the industrial robotic arm 2 to drive the laser gun 3 to reset.

[0104] Subsequently, the PLC controller restarted the first servo motor 6, driving the conveyor belt 5 to continue rotating, sending the mounting assembly 8 containing the dressed diamond grinding wheel 10 out of the opening on the other side of the laser dressing chamber 1. During the sending process, the curtain 9 at the opening was pushed open again, and closed again after the grinding wheel was completely sent out.

[0105] The operator can remove the dressed diamond grinding wheel 10 from the conveyor belt 5 and install the diamond grinding wheel 10 to be dressed onto the empty mounting assembly 8, and the equipment will enter the next working cycle.

[0106] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
