DETAILED DESCRIPTION

[0038] The present invention is described in detail below with reference to the accompanying drawings.

[0039] like Figures 1 to 9 As shown, a lens water outlet cutting device of the present invention includes a general control system, a material receiving mechanism 1, a sensor module, a transfer mechanism 2, a shearing mechanism 3, a material conveying mechanism 4, a grinding mechanism 5, a temporary storage tray 6, a first material receiving mechanism 7, a second material receiving mechanism 8 and a material storage warehouse 9.

[0040] The first material receiving mechanism 7 and the second material receiving mechanism 8 are both conventional multi-axis suction cup manipulators. The material storage warehouse 9 is a conventional lifting material storage warehouse.

[0041] The master control system is electrically connected to the material receiving mechanism 1, the sensor module, the transfer mechanism 2, the shearing mechanism 3, the material conveying mechanism 4, the grinding mechanism 5, the first material receiving mechanism 7, the second material receiving mechanism 8 and the material storage 9 for information processing.

[0042] The receiving mechanism 1 is used to receive the plastic products and convey them to the transfer mechanism 2;

[0043] The sensor module is used to obtain the material and position of the plastic product, the shear point at the connection between the plastic product and the nozzle, and the image of the shear bulge at the shearing point between the plastic product and the nozzle and feed it back to the master control system;

[0044] The transfer mechanism 2 is used to receive the plastic products conveyed by the receiving mechanism 1. The master control system controls the transfer mechanism 2 to adjust the angle of the plastic products and then transfer them to the shearing mechanism 3.

[0045] The shearing mechanism 3 is used to shear the plastic product to cut off the water outlet of the plastic product;

[0046] The material transfer mechanism 4 is used to transfer the plastic product between the shearing mechanism 3 and the grinding mechanism 5;

[0047] The grinding mechanism 5 is used for grinding the shearing protrusion;

[0048] The temporary storage tray 6 is used to hold the polished plastic products;

[0049] The first material receiving mechanism 7 is used to receive the polished plastic products and transport them to the temporary storage tray 6;

[0050] The second material receiving mechanism 8 drives the first material receiving mechanism 7 to move and is used to transport the temporary storage tray 6 to the material storage warehouse 9;

[0051] The storage warehouse 9 is used to store the temporary storage tray 6 containing plastic products;

[0052] How the Resection Device Works:

[0053] A. The receiving mechanism 1 receives the plastic products and conveys them to the transfer mechanism 2. During the conveying process of the plastic products, the sensor module obtains the material, position and shearing point between the plastic products and the nozzle and feeds them back to the master control system;

[0054] B. The transfer mechanism 2 receives the plastic product delivered by the receiving mechanism 1. The master control system obtains the material and position of the plastic product and the shearing point of the plastic product and the nozzle according to the sensor module to control the transfer mechanism 2 to adjust the angle of the plastic product and then transfer it to the shearing mechanism 3;

[0055] C. The material conveying mechanism 4 clamps the plastic product on the transfer mechanism 2, and the shearing mechanism 3 shears the shearing point between the plastic product and the nozzle to separate the plastic product from the nozzle. The material conveying mechanism 4 clamps the plastic product and transfers it to the polishing mechanism 5;

[0056] D. The polishing mechanism 5 polishes the shearing protrusion at the shearing point between the plastic product and the nozzle. The sensor module obtains the image of the shearing protrusion during polishing and feeds it back to the master control system. The master control system adjusts the number of polishing times and the depth of polishing of the polishing mechanism 5 according to the image of polishing fed back by the sensor module, so that the plastic product is polished;

[0057] E..The second receiving mechanism 8 drives the first receiving mechanism 7 to receive the polished plastic products and transport them to the temporary storage tray 6;

[0058] F. The second material receiving mechanism 8 transports the temporary storage tray 6 to the material storage warehouse 9.

[0059] Through the cooperation of sensors and the master control system, automatic nozzle cutting, grinding and finished product storage are realized, which reduces the error of manual operation and improves production efficiency. The sensor module is used to provide real-time feedback on the shearing point and grinding status, ensuring the accuracy of each shearing and grinding, and reducing the production of defective products.

[0060] This application integrates the functions of material connection, cutting, grinding, transmission, storage, etc., with a complete process, reducing the time loss and material waste in process conversion. Through the real-time detection of the material and position of plastic products by sensors, it can adapt to plastic products of different materials and flexibly respond to production needs.

[0061] Compared with traditional technology, the lens water outlet cutting device of the present application integrates multiple functions such as material receiving, conveying, shearing, grinding, and storage. It utilizes real-time monitoring and feedback from sensors and the master control system to realize automated operation, overcoming the problems of errors, low efficiency, and inconsistent quality in traditional technology, and significantly improving production efficiency and product quality.

[0062] like Figure 3 As shown, the material receiving mechanism 1 of this embodiment includes a lifter 11 , a lift seat 12 , a rotator 13 , a material receiving platform 14 and a fixing seat 15 .

[0063] The lifter 11 drives the lifting seat 12 to rise and fall, so that the material receiving mechanism 1 can flexibly adjust the material receiving position according to the different heights of the conveyed plastic products, ensuring that the plastic products can be smoothly placed in the fixing seat 15, thereby improving the adaptability of the equipment.

[0064] The rotator 13 is rotatably disposed on the lifting seat 12 and drives the receiving platform 14 to rotate, and a reset member is disposed between the rotator 13 and the lifting seat 12. Specifically, the reset member in this embodiment is an example of a reset torsion spring.

[0065] In other embodiments, the reset element may be a servo motor, which has a position feedback function, can achieve precise rotation control through a controller, and can set a reset position to achieve automatic reset after rotation. The servo motor is suitable for application scenarios that require stable and high-speed rotation.

[0066] The fixing seat 15 is fixed to the material receiving platform 14 . The fixing seat 15 is provided with a clamping groove 151 for fixing the water outlet of the plastic product. The plastic product is fixed by the clamping groove 151 .

[0067] The lifting seat 12 is provided with a limit plate 121 and a buffer screw 122 . The buffer screw 122 is provided on the limit plate 121 and is located directly above the rotator 13 .

[0068] The lifter 11 is one of a cylinder lift mechanism, an electric screw lift mechanism, a hydraulic lift mechanism, or a chain or gear lift mechanism.

[0069] The cylinder lifting mechanism uses air pressure to push the piston to achieve lifting action. The cylinder has the advantages of fast response, simple structure and low cost, and is suitable for occasions with high speed and precision requirements.

[0070] The electric screw lifting mechanism drives the screw to rotate through the motor, driving the nut to move up and down to achieve lifting. This mechanism has high precision and is suitable for application scenarios that require stable and precise control of the lifting position.

[0071] The hydraulic lifting mechanism uses liquid pressure to push the piston to move and achieve lifting. The hydraulic system is suitable for applications with large loads, has high load-bearing capacity and stability, and is suitable for occasions where heavy objects need to be carried.

[0072] The chain or gear lifting mechanism realizes lifting action through chain or gear transmission. It has a simple structure and good stability, which is suitable for design scenes with compact space.

[0073] Working method of receiving mechanism 1:

[0074] A1. The lifter 11 drives the lift seat 12 to rise to a preset position, and the plastic product is placed on the fixed seat 15 by the robot;

[0075] A2. During the placement process of the robot, the robot tilts and presses the plastic product down on the fixed seat 15 so that the receiving table 14 rotates through the rotator 13 and pulls the reset member to change shape to match the tilt and downward angle of the robot, so that the plastic product is completely placed in the fixed seat 15 and clamped in the clamping groove 151;

[0076] A3. After the plastic product is stuck in the slot 151, the manipulator releases the plastic product and moves away from the receiving mechanism 1, and the receiving platform 14 is restored to its original state through the cooperation of the rotator 13 and the reset member and contacts the buffer screw 122;

[0077] A4. The lifter 11 drives the lift base 12 to descend to a preset position.

[0078] The setting of using the rotator 13 to drive the receiving platform 14 to rotate allows the receiving platform 14 to adjust its angle during the process of the robot arm tilting and pressing down, ensuring that the plastic product can be accurately placed in the slot 151 of the fixing seat 15. The rotational coordination between the rotator 13 and the receiving platform 14 improves the positioning accuracy of the plastic product and reduces the need for manual adjustment.

[0079] The design of the buffer screw 122 and the limit plate 121 provides a protection mechanism to prevent excessive movement, thereby avoiding damage to the equipment due to excessive movement or misoperation, and also ensures the smooth and safe operation of the material receiving mechanism.

[0080] The slot 151 designed on the fixing seat 15 effectively fixes the nozzle part of the plastic product, ensures the stability and accuracy in subsequent operations, and avoids shearing or grinding errors caused by the movement of the product.

[0081] like Figure 3 As shown, the material receiving platform 14 of this embodiment is provided with a material pressing mechanism 16 , and the material pressing mechanism 16 includes a material pressing driver 161 , a rotary actuator 162 and a pressing sheet 163 .

[0082] The pressing drive 161 is a cylinder drive or an electric push rod, and the rotating actuator 162 is a servo motor or a pneumatic rotary actuator.

[0083] The material pressing driver 161 is fixed to the material receiving platform 14 and is used to drive the rotary actuator 162 to move up and down. The material pressing driver 161 is a pneumatic cylinder or an electric cylinder.

[0084] The rotary actuator 162 drives the pressing plate 163 to rotate.

[0085] When the plastic product is clamped in the clamping slot 151, the pressing drive 161 drives the rotary actuator 162 to descend, and at the same time, the rotary actuator 162 drives the pressing sheet 163 to rotate above the plastic product. When the pressing drive 161 drives the rotary actuator 162 to descend to the preset position, the pressing sheet 163 contacts the plastic product, preventing the plastic product from separating from the fixing seat 15 during the process of the lifter 11 driving the lifting seat 12 to descend. The pressing sheet can accurately cover the top of the plastic product, improving the flexibility and accuracy of the plastic product fixation. It ensures that the plastic product always remains in a stable fixed state during the conveying, shearing or grinding operation, improving the overall processing accuracy.

[0086] This design reduces the movement error of plastic products during processing, reduces the defective rate, ensures the smooth progress of subsequent processes, and further improves the stability and work efficiency of automated processing equipment.

[0087] like Figure 3 and Figure 4 As shown, a central hole 152 is provided inside the fixing seat 15 of this embodiment, and an opening 153 is provided on one side of the fixing seat 15 , and the opening 153 is communicated with the central hole 152 .

[0088] The transfer mechanism 2 includes a transfer drive 21 , a conveying table 22 , a transfer drive 23 , a transfer fixture 24 , a pushing drive 25 , a shearing seat 26 and a shearing adjustment actuator 27 .

[0089] The transfer drive 21, the transfer drive 23 and the push drive 25 are all linear drives, such as conventional screw linear drives, conventional synchronous belt linear drives or conventional linear motor linear drives. The transfer clamp 24 is a conventional pneumatic clamp or a conventional hydraulic clamp. The shear adjustment actuator 27 is a conventional electric rotary drive, a conventional pneumatic rotary drive or a conventional hydraulic rotary drive.

[0090] The transfer driver 21 is arranged directly below the material receiving mechanism 1, and the conveying table 22 is fixed to the transfer driver 21. The transfer driver 21 is used to drive the conveying table 22 to slide between the transfer driver 23 and the material receiving mechanism 1, so that the plastic products can be stably and accurately conveyed from the material receiving mechanism 1 to the shearing mechanism 3, realizing automated conveying operation, reducing manual intervention, and improving production efficiency.

[0091] The transfer driver 23 is arranged at one side of the transfer driver 21, the transfer fixture 24 is fixed to the side of the transfer driver 23 facing the transfer driver 21, the push driver 25 is arranged between the transfer driver 23 and the shearing mechanism 3, the shearing adjustment actuator 27 is fixed to the push driver 25, and the shearing seat 26 is fixed to the shearing adjustment actuator 27;

[0092] The sensor module includes a vision camera and an angle encoder.

[0093] The visual camera is used to obtain images of the position of the plastic product and feed them back to the master control system. The master control system obtains the position of the plastic product in three-dimensional space and the position of the shear point through image processing.

[0094] The angle encoder is disposed on the shear adjustment actuator 27 and is used to monitor the angle change of the shear adjustment actuator 27 .

[0095] The transfer mechanism 2 receives the plastic products conveyed by the receiving mechanism 1 and conveys the plastic products to the shearing mechanism 3 to separate the plastic products from the nozzle before cutting:

[0096] B1. The lifter 11 drives the lift seat 12 to descend to the same level as the conveying platform 22, the fixed seat 15 is suspended on the periphery of the conveying platform 22, and when the conveying platform 22 is located in the middle hole 152, the plastic product is located above the conveying platform 22;

[0097] B2. The lifter 11 drives the lift seat 12 to descend to a position below the horizontal height of the conveying platform 22, and the plastic product is placed on the conveying platform 22. The transfer driver 21 drives the conveying platform 22 to slide away from the receiving mechanism 1 through the opening 153 of the fixed seat 15 and conveys the plastic product carried on the conveying platform 22 to a preset position close to the transfer driver 23, so that the transfer mechanism 2 receives the plastic product conveyed by the receiving mechanism 1;

[0098] B3. The image of the position of the plastic product obtained by the visual camera is fed back to the master control system. The master control system obtains the position of the plastic product in three-dimensional space through image processing. The master control system controls the transfer driver 23 to drive the transfer fixture 24 close to the conveying table 22. The transfer fixture 24 clamps the plastic product carried on the conveying table 22;

[0099] B4. The transfer driver 23 drives the transfer fixture 24 close to the push driver 25 and places the plastic product on the shear seat 26;

[0100] B5. The master control system obtains the image of the position of the plastic product through the visual camera and processes it to obtain the shearing point of the plastic product. The master control system controls the shearing adjustment actuator 27 to drive the shearing seat 26 to rotate to adjust the shearing point of the plastic product. The angle encoder monitors the angle change of the shearing adjustment actuator 27 and feeds back to the master control system. During the adjustment process of the shearing point of the plastic product, the visual camera obtains the image of the shearing point position of the plastic product in real time and feeds back to the master control system. The master control system confirms the adjustment result so that the shearing point of the plastic product is toward the shearing mechanism 3.

[0101] The visual camera obtains the three-dimensional position image of the plastic product and feeds it back to the master control system to ensure that the plastic product always maintains the accurate position during the conveying and shearing process. The angle encoder is used to monitor the angle change of the shear adjustment actuator 27 and feed it back to the master control system in real time, making the shear point adjustment more accurate.

[0102] The combined design of the transfer driver 23 and the transfer fixture 24 makes the transfer process of the plastic product more stable and accurate, avoids vibration and misalignment during the transfer process, and ensures that the shearing point of the plastic product can be accurately aligned with the shearing mechanism 3.

[0103] The shear adjustment actuator 27 automatically adjusts the shear point position of the plastic product and cooperates with the feedback of the angle encoder to achieve high-precision control of the shearing process. During the shear point adjustment process, the visual feedback system monitors in real time, further improving the accuracy and consistency of the shearing operation.

[0104] like Figure 5 As shown, the shearing mechanism 3 of this embodiment includes a shearing driver 31 and a cutter 32. There are two cutters 32. The two cutters 32 are relatively fixed to the shearing driver 31. The shearing driver 31 drives the two cutters 32 to approach or move away from each other. When the shearing driver 31 drives the two cutters 32 to approach each other, the shearing point at the shearing point between the plastic product and the nozzle is cut. After the shearing point at the shearing point between the plastic product and the nozzle is cut, the shearing driver 31 drives the two cutters 32 to move away from each other. Efficient nozzle shearing operation is achieved, ensuring a smooth and accurate shearing process.

[0105] The shearing drive 31 may be an electric drive, a pneumatic drive or a hydraulic drive. The electric drive may be an electric cylinder, the pneumatic drive may be an air cylinder, and the hydraulic drive may be a hydraulic cylinder.

[0106] The material transfer mechanism 4 includes a clamping manipulator 41, wherein the clamping manipulator 41 is a cylinder clamping manipulator or an oil cylinder clamping manipulator. The clamping manipulator 41 clamps the plastic product, effectively ensuring the transfer stability of the plastic product between the shearing and grinding processes, reducing the processing error caused by the sliding or displacement of the workpiece, and improving the continuity and reliability of the overall production.

[0107] The sensor module includes an ultrasonic sensor and a first torque sensor.

[0108] Ultrasonic sensors are used to identify the material properties of plastic products through specific wavelengths or spectral reflections and feed them back to the master control system, allowing the master control system to optimize and adjust the shearing and grinding processes in real time according to the characteristics of the material, adapt to plastic products of different materials, and improve processing accuracy and product quality.

[0109] The first torque sensor is arranged on the shear driver 31 to measure the force applied during the actual shearing process and feed it back to the master control system, so that the system can adjust the shearing parameters according to the actual shearing force to prevent over-shearing or under-shearing, thereby extending the service life of the equipment and reducing the scrap rate.

[0110] The method for shearing the shearing part between the plastic product and the nozzle by the shearing mechanism 3 is as follows:

[0111] C1. The push driver 25 drives the shear adjustment actuator 27 and the shear seat 26 to approach the shear driver 31, and the plastic product passes through the two cutters 32 and extends into the clamping claw of the clamping manipulator 41 of the material conveying mechanism 4, and the shearing point of the plastic product is placed between the two cutters 32;

[0112] C2. The material transfer mechanism 4 holds the plastic product by the clamping manipulator 41;

[0113] C3. The master control system identifies the material properties of the plastic product through a specific wavelength or spectral reflection by the ultrasonic sensor and feeds back to the master control system. The master control system selects a preset shear force to control the shear driver 31 according to the preset material properties of the plastic product;

[0114] C4. The shearing driver 31 drives the two cutters 32 to approach each other according to the preset shearing force to cut off the shearing point where the plastic product and the water outlet are sheared.

[0115] The shearing mechanism 3 drives the shearing adjustment actuator 27 and the shearing seat 26 to approach the shearing driver 31 through the push driver 25, so that the plastic product accurately enters the shearing area of ​​the cutter 32. This design ensures the accuracy of the shearing position of the plastic product and effectively avoids the problem of poor shearing due to workpiece misalignment.

[0116] The clamping manipulator 41 in the material conveying mechanism 4 clamps the plastic product to keep it stably during the shearing process, thereby preventing shearing errors caused by unstable materials and ensuring the smooth progress of the shearing process.

[0117] The master control system uses ultrasonic sensors to identify the material properties of plastic products through wavelength or spectral reflection, and selects the most appropriate shear force based on the different characteristics of the materials. This ensures accurate shearing of plastic products made of different materials, avoiding over-shearing or under-shearing caused by using a single shear force.

[0118] The shear driver 31 accurately controls the approach of the two cutters 32 according to the preset shear force to ensure smooth separation of the shear point. Combined with material identification feedback, the shear force can be adjusted according to the hardness or thickness of the plastic product, avoiding unnecessary mechanical wear and improving the shear quality.

[0119] The overall design achieves efficient and precise separation of plastic products from the nozzle by automatically adjusting the shear force and shear point position, reduces processing defects caused by differences in material properties, improves the intelligence level and production efficiency of the equipment, and reduces the scrap rate.

[0120] In actual use, plastic products are specifically divided into low hardness plastics, medium hardness plastics, high hardness plastics and ultra-high hardness plastics.

[0121] Low hardness plastics (Shore hardness A40-60, such as soft PVC, TPU):

[0122] Shear force: 50-100N

[0123] Shearing characteristics: This soft material is easier to cut and can be cut with a smaller shearing force. At the same time, it is necessary to avoid excessive shearing force that may cause material deformation or burrs.

[0124] Medium hardness plastics (Shore hardness A70-80, such as PE, PP, and ordinary ABS):

[0125] Shear force: 100-200N

[0126] Shearing characteristics: Medium hardness plastics require moderate shearing force to ensure smooth shearing while maintaining the flatness of the cut surface. Larger shearing force helps prevent tearing or incomplete breaking of the plastic during cutting.

[0127] High hardness plastic (Shore hardness A85-95, such as PA (nylon), PC, reinforced ABS):

[0128] Shear force: 200-400N

[0129] Shearing characteristics: For harder plastics, higher shearing forces can ensure clean and rapid cutting, avoiding incomplete cutting due to insufficient shearing force. Especially when encountering reinforced materials, higher shearing forces can also avoid the resistance caused by fibers or fillers inside the material.

[0130] Ultra-high hardness plastics (Shore hardness D70-80, such as POM, polyimide, and some glass fiber reinforced composite materials):

[0131] Shear strength: 400-600N

[0132] Shearing characteristics: Due to their high hardness, these materials require greater shearing force to ensure smooth cutting. At the same time, the stability of the equipment must be maintained during the shearing process to avoid cutting delays or uneven surfaces due to insufficient force.

[0133] These shear force options can be fine-tuned based on the hardness and thickness of the specific material. The master control system can use sensors to identify material properties and automatically adjust the shear force.

[0134] Preferably, the shearing mechanism 3 further includes a mobile driver 33, which drives the shearing driver 31 to move close to the shearing seat 26, so that the shearing driver 31 drives the cutter 32 to cut the shearing point of the shearing position between the plastic product and the nozzle. The mobile driver 33 drives the shearing driver 31 to move away from the shearing seat 26 to avoid interfering with the material conveying mechanism 4.

[0139] When in use, the turntable mechanism 42 drives the clamping manipulator 41 to stop at the material receiving station 421, and the clamping manipulator 41 clamps the plastic product to facilitate cutting the water outlet of the plastic product. The turntable mechanism 42 drives the clamping manipulator 41 to stop at the polishing station 422, and the shearing protrusion is polished by the polishing mechanism 5, which effectively improves the surface finish of the plastic product. The turntable mechanism 42 drives the clamping manipulator 41 to stop at the inspection station 423, and the quality inspection visual camera obtains the surface image of the plastic product and feeds it back to the main control system, and the quality of the polishing of the plastic product is inspected or evaluated, thereby improving the qualified rate of the plastic product, reducing the defective rate, and improving the product quality. The turntable mechanism 42 drives the clamping manipulator 41 to stop at the transfer station 424, so that the first material receiving mechanism 7 can receive the polished plastic product and transport it to the temporary storage tray 6.

[0140] Through the automated process, manual intervention is reduced, and the production speed and efficiency of the product are significantly improved. The continuous rotation of the turntable mechanism 42 and the precise positioning of the clamping manipulator 41 ensure the seamless connection between each station, shorten the production cycle, and improve production efficiency.

[0141] Traditional manual production lines require a lot of manpower input, while the automated material conveying mechanism reduces the need for manual operation, reduces labor costs, and at the same time reduces the labor intensity of workers and reduces labor costs.

[0142] By adjusting the rotation speed of the turntable mechanism 42 and the number of the clamping robots 41, the production needs of different production scales and product types can be flexibly adapted, thereby improving the flexibility and adaptability of the production line and enhancing production flexibility.

[0143] Automated production lines reduce workers’ direct contact with dangerous equipment, reduce the risk of work-related accidents, improve workplace safety, and increase work safety.

[0144] The automated production line is equipped with advanced control systems and sensor modules, which can monitor production status and equipment performance in real time, making it easier for managers to schedule production and maintain equipment, thereby improving the efficiency and accuracy of production management and facilitating management and maintenance.

[0145] Preferably, a translation driver 43 is provided between the turntable mechanism 42 and the clamping manipulator 41, and the translation driver 43 drives the clamping manipulator 41 to extend and retract. When the turntable mechanism 42 rotates, the translation driver 43 drives the clamping manipulator 41 to retract into the turntable mechanism 42, so as to avoid interference between the clamping manipulator 41 and the shearing mechanism 3 and the grinding mechanism 5, so as to make the turntable mechanism 42 rotate smoothly. When the turntable mechanism 42 stops, the translation driver 43 drives the clamping manipulator 41 to extend out of the turntable mechanism 42, so as to facilitate the clamping manipulator 41 to operate in the material receiving station 421, the grinding station 422, the inspection station 423 and the transfer station 424. The translation driver 43 is an electric driver, a pneumatic driver or a hydraulic driver, and the electric driver is such as an electric cylinder, the pneumatic driver is such as an air cylinder, and the hydraulic driver is such as a hydraulic cylinder.

[0146] like Figure 7 As shown, the grinding mechanism 5 of this embodiment includes a fixing frame 51 , a fixing fixture 52 , a grinding head 53 and a grinding driver 54 .

[0147] The fixing fixture 52 is fixed to one end of the fixing frame 51 , and the grinding driver 54 is disposed at the other end of the fixing frame 51 ;

[0148] An end of the fixing jig 52 away from the fixing frame 51 is provided with an extended frame 521 for fixing the plastic product, and the plastic product is restricted by the extended frame 521. An end of the fixing jig 52 close to the fixing frame 51 is provided with a grinding opening 522, and the shearing part of the plastic product and the nozzle is exposed in the grinding opening 522. The grinding opening 522 facilitates the grinding of the shearing protrusion of the shearing part of the plastic product and the nozzle, and the grinding opening 522 can also protect other parts of the plastic product from being polished.

[0149] The grinding driver 54 drives the grinding head 53 to move along the grinding opening 522 to grind the shearing point between the plastic product and the water outlet.

[0150] By precisely controlling the grinding driver 54, the moving speed, direction and force of the grinding head 53 can be controlled according to a preset program or operating instruction, thereby achieving precise grinding of the shear point between the plastic product and the nozzle, which helps to ensure the quality and efficiency of grinding.

[0151] Among them, the grinding driver 54 is an XY axis driving mechanism, a conventional XY axis driving mechanism such as a driving module of a ball screw and a linear guide, a driving module of a synchronous toothed belt and a linear guide, or a dual motor driving module, so as to realize that the grinding driver 54 drives the grinding head 53 to move along the XY axis.

[0152] like Figure 8 As shown, the grinding head 53 of this embodiment includes a fixed shell 531 , a sliding shell 532 , a telescopic driver 533 , a grinding actuator 534 and a grinding wheel 535 .

[0153] The telescopic driver 533 is a linear driver, such as a conventional screw linear driver, a conventional synchronous belt linear driver or a conventional linear motor linear driver. The grinding actuator 534 is a motor.

[0154] The fixed shell 531 is fixed to the grinding driver 54 and is slidably connected to the sliding shell 532 , so that the grinding head 53 is connected to the grinding driver 54 , so that the grinding driver 54 drives the grinding head 53 .

[0155] The sliding shell 532 is provided with an articulated arm 536, one end of the articulated arm 536 is hinged to the sliding shell 532, and the other end of the articulated arm 536 is slidably connected to the fixed frame 51. Through the design of the articulated arm 536, the grinding head can be flexibly adjusted in angle relative to the fixed frame 51, which enables the grinding process to better adapt to workpieces of different shapes and curves, thereby improving the grinding accuracy and efficiency.

[0156] The telescopic driver 533 is fixed to the fixed shell 531 and is used to drive the sliding shell 532 to slide along the fixed shell 531, and can accurately control the sliding of the sliding shell 532 in the fixed shell 531, thereby achieving fine adjustment of the position of the grinding wheel 535. This design helps to achieve more precise control and more uniform grinding effect during the grinding process.

[0157] The grinding actuator 534 fixes the sliding shell 532 and is used to drive the grinding wheel 535 to rotate. The grinding actuator 534 is directly fixed to the sliding shell 532 and is used to drive the grinding wheel 535 to rotate. This direct drive method reduces the loss of power transmission, improves energy utilization efficiency, and makes the grinding process more efficient. The shearing protrusion is polished by the rotating grinding wheel 535 contacting the shearing protrusion.

[0158] The entire grinding head has a compact structure, with each component tightly connected and clearly defined in function. This design not only reduces the overall size, but also facilitates subsequent maintenance and replacement, reducing the cost of use.

[0159] By precisely controlling the position and speed of the grinding wheel, the grinding head can reduce the risks to operators and workpieces while ensuring the grinding effect, thereby improving the safety of the production process.

[0160] Preferably, the sliding shell 532 is provided with a slide bar 5321, the slide bar 5321 is hinged with the sliding shell 532, a guide slider 5311 and a limit block 5312 are provided in the fixed shell 531, and the slide bar 5321 slides along the guide slider 5311 to achieve a sliding connection between the fixed shell 531 and the sliding shell 532. The limit block 5312 is used to contact the slide bar 5321, and the limit block 5312 contacts the slide bar 5321, so that the guide slider 5311 is limited, thereby controlling the sliding stroke of the sliding shell 532.

[0161] like Fig. 9 As shown, specifically, the articulated arm 536 includes a first connection seat 5361, a second connection seat 5362, a cross rotating member 5363 and a telescopic member 5364. The first connection seat 5361 is fixedly connected to the fixed frame 51, and the second connection seat 5362 is fixedly connected to the sliding shell 532. There are two cross rotating members 5363, and both ends of the telescopic member 5364 are respectively hinged to the first connection seat 5361 and the second connection seat 5362 through the cross rotating member 5363. One end of the articulated arm 536 is hinged to the sliding shell 532, and the other end of the articulated arm 536 is hinged to the fixed frame 51.

[0162] The telescopic member 5364 includes a first telescopic sleeve 5365, a sliding member 5366 and a second telescopic sleeve 5367. The first telescopic sleeve 5365 and the second telescopic sleeve 5367 are respectively hinged to the cross rotating member 5363, and the first telescopic sleeve 5365 and the second telescopic sleeve 5367 are respectively slidably connected to the sliding member 5366. In this way, the sliding shell 532 and the fixing frame 51 are hinged through the hinge arm 536 and have a certain telescopic margin, so that the sliding shell 532 can move along the fixing frame 51 more flexibly and stably.

[0163] In other embodiments, the telescopic member 5364 may also be a spring or an elastic rubber member, so that the telescopic member 5364 has a certain telescopic margin.

[0164] The extended frame 521 of this embodiment includes an upper edge, a middle edge and a lower edge.

[0165] The upper edging, the middle edging and the lower edging cooperate to wrap at least one third of the area of ​​the plastic product, so that the extended frame 521 cooperates with the material conveying mechanism 4 to fix the plastic product, making it easy to polish the shear protrusion at the shearing point between the plastic product and the water outlet.

[0166] A collecting box is provided below the fixing frame 51 , and a negative pressure suction pipe is provided at one end of the collecting box close to the grinding head 53 . Grinding debris is collected through the negative pressure suction pipe, so as to facilitate recycling of the grinding debris.

[0167] The sensor module of this embodiment includes a second torque sensor, a friction coefficient tester and a camera module.

[0168] The second torque sensor is used to detect the pressure applied by the grinding wheel 535 on the plastic product in real time.

[0169] The friction coefficient tester is used to detect the friction coefficient between the grinding wheel 535 and the plastic product in real time.

[0170] The friction coefficient tester is used to detect the friction coefficient between the grinding wheel 535 and the plastic product in real time.

[0171] The formula for grinding pressure P(t) is:

[0172] P(t)=K1·(F s -F m )

[0173] The formula for grinding speed V(t) is:

[0174] V(t)=K2·(μ s -μ m )

[0175] Among them, F S is the preset standard torque value, F m is the grinding torque measured in real time; μ s is the preset standard friction coefficient, μ m is the friction coefficient measured in real time; K1 and K2 are adjustment coefficients. The value range of K1 and K2 is 0-5. In this embodiment, K1=2 and K2=1.5 are used as an example.

[0176] The pressure applied by the grinding wheel 535 to the plastic product is detected in real time by the second torque sensor, and the friction coefficient tester detects the friction coefficient between the grinding wheel 535 and the plastic product in real time and feeds back to the master control system.

[0177] When in use, the master control system uses an ultrasonic sensor to identify the material properties of the plastic product through specific wavelength or spectral reflection. The master control system adjusts the grinding pressure P(t) of the telescopic driver 533 according to the hardness of the plastic product material and the formula of the grinding pressure P(t), and adjusts the grinding speed V(t) of the grinding actuator 534 according to the formula of the grinding speed V(t).

[0178] The second torque sensor and the friction coefficient tester can detect the pressure applied by the grinding wheel on the plastic product and the friction coefficient between the grinding wheel and the plastic product in real time, and dynamically adjust the grinding pressure and speed according to the hardness of the plastic product material. This real-time feedback and adjustment mechanism ensures the accuracy and efficiency of the grinding process and avoids excessive or insufficient grinding caused by fixed parameters.

[0179] For different commonly used plastic products, the standard torque value range preset by FS is different.

[0180] For example:

[0181] For softer plastics (such as PE), FS can be set in a lower range, such as 10-20 Nm. This embodiment takes FS as 15 Nm as an example.

[0182] For plastics with medium hardness (such as PP, PS), FS can be set in a medium range, such as 20-30Nm. S This is an example of 25Nm.

[0183] For harder plastics (such as nylon PA), F S It can be set in a higher range, such as 30-40Nm. S This is an example of 35Nm.

[0184] μ s It is a relatively fixed value, which represents the basic friction characteristics between materials without lubrication or under specific conditions. For most plastic products under dry friction conditions, μ s It can be set in the range of 0.2-0.5. s This is an example of 0.3.

[0185] The total length L of the grinding path is:

[0186]

[0187] Where (x i ,y i ) is the coordinate of each key point on the polishing path, and n is the length of the path between two key points.

[0188] When in use, the camera module obtains the image of the shearing protrusion and feeds it back to the main control system. The main control system captures the position and shape of the shearing protrusion based on the shearing protrusion image fed back by the camera module through image recognition, and uses each protrusion shape as a key point of the grinding path. The key points are connected to generate a grinding path for controlling the grinding wheel 535. The main control system dynamically adjusts the grinding path and calculates the shortest grinding path based on the total length L of the grinding path. The shearing protrusion is ground with the shortest grinding path to reduce the grinding time.

[0189] The camera module is used to obtain images of the shearing protrusions, and the key points are captured through image recognition technology to generate the shortest grinding path. This method not only reduces the grinding time, but also improves the grinding accuracy and avoids unnecessary material removal, thereby protecting the integrity and aesthetics of the plastic product.

[0190] Grinding depth d(t) adjustment formula:

[0191] d(t)=d init -K4·(Q meas -Q std );

[0192] Adjustment formula of grinding times N(t):

[0193] N(t)=N init +K5·(Q meas -Q std );

[0194] Among them, d ini is the initial grinding depth, N init is the initial grinding times, Q meas is the measured polished surface finish, Q std is the standard finish, K4 and K5 are adjustment factors for depth and number of passes.

[0195] d ini The initial grinding depth ranges from 0.1 mm to 1.0 mm. ini =0.5mmExample.

[0196] Q std The standard smoothness ranges from 0 to 50 units of smoothness. In this embodiment, Q std =10 unit finish example.

[0197] The value range of K4 is between 0.01 and 0.1, and the value range of K5 is between 0.1 and 1.0. In this embodiment, the setting value of K4 is 0.05 mm / unit of smoothness, and the setting value of K5 is 0.5 times / unit of smoothness.

[0198] The master control system performs image recognition based on the image of the shearing protrusion fed back by the camera module in real time. The master control system determines the surface smoothness of the plastic product after the shearing protrusion is polished based on the image recognition result of the shearing protrusion, and thus dynamically adjusts the polishing depth d(t) of the extension stroke of the telescopic drive 533 and the number of times N(t) that the polishing drive 54 moves back for polishing based on the polishing depth d(t) adjustment formula.

[0199] Based on the shear bulge image fed back by the camera module in real time, the master control system can dynamically evaluate the surface finish after grinding and adjust the grinding depth and number of times accordingly. This intelligent adjustment mechanism ensures that no matter what the initial state of the plastic product is, the ideal surface quality can be achieved in the end, improving the overall quality and consistency of the product.

[0200] By precisely controlling grinding parameters and paths, and dynamically adjusting grinding strategies, this technical solution significantly improves production efficiency and product quality, while reducing material waste and processing time caused by over-grinding or under-grinding, thereby reducing production costs.

The content of this specification should not be understood as limiting the present invention.
