Technical Field

[0001] The present invention relates to the technical field of nozzle removal, and in particular to a nozzle removal device for a lens. Background Art

[0002] The sprue is usually a connection part formed during the injection molding or casting process to introduce molten plastic or material into the mold and needs to be removed after molding.

[0003] Water nozzle cutting refers to the trimming of the water nozzle part produced during the molding process of plastic products or models, and the polishing of the shear protrusion at the shear point between the plastic product and the water nozzle, so that the surface of the plastic product is smooth, beautiful, and meets the design requirements.

[0004] In traditional plastic product production, nozzle cutting and polishing are typically separate processes, often performed manually. Traditional production methods rely heavily on manual labor for these tasks, which require precise operation and are prone to errors, resulting in low-quality finished products. Therefore, improvements are necessary. Summary of the Invention

Through the cooperation of sensors and a master control system, it realizes automated sprue cutting, polishing and finished product storage, reduces manual operation errors and improves production efficiency; uses the sensor module to provide real-time feedback on the shearing point and polishing status, ensures the accuracy of each shearing and polishing, and reduces the production of defective products.

[0006] To achieve the above-mentioned purpose, the present invention provides a lens nozzle cutting device, comprising a master control system, a material receiving mechanism, a sensor module, a transfer mechanism, a shearing mechanism, a material conveying mechanism, a grinding mechanism, a temporary storage tray, a first material receiving mechanism, a second material receiving mechanism, and a material storage.

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 transmission 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, and 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 feeding mechanism 4, the grinding mechanism 5, the first material receiving mechanism 7, the second material receiving mechanism 8 and the material storage 9 and is used for information processing.

[0042] The receiving mechanism 1 is used to receive plastic products and transport 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 delivered 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 remove the sprue of the plastic product;

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

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

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

[0049] The first 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 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, the sensor module obtains the material, position, and shearing point between the plastic products and the nozzle and feeds back to the master control system.

[0054] B. Transfer mechanism 2 receives the plastic product delivered by receiving mechanism 1. The master control system uses the sensor module to obtain the material and position of the plastic product, as well as the shear point where the plastic product and the nozzle are sheared, to control transfer mechanism 2 to adjust the angle of the plastic product before transferring it to 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 plastic product at the shear point where the plastic product and the nozzle are sheared 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 shear protrusions at the shearing point between the plastic product and the nozzle. The sensor module obtains an image of the shear protrusions during polishing and feeds it back to the master control system. The master control system adjusts the number of polishing times and the polishing depth of the polishing mechanism 5 based on the image feedback from the sensor module to ensure 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] The collaboration of sensors and the master control system enables automated nozzle cutting, polishing, and finished product storage, reducing manual operation errors and improving production efficiency. The sensor module provides real-time feedback on the cutting point and polishing status, ensuring the accuracy of each cutting and polishing process and reducing the number of defective products.

[0060] This application integrates functions such as material connection, cutting, grinding, conveying, and storage, providing a complete process and reducing time loss and material waste during process conversion. Through real-time sensor detection of the material and position of plastic products, it can adapt to plastic products of different materials and flexibly respond to production needs.

[0061] Compared with traditional technology, the lens sprue cutting device of this application integrates multiple functions such as material receiving, conveying, shearing, polishing, and storage. It uses 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 move up and down, 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 arranged on the lifting seat 12 and drives the material receiving platform 14 to rotate, and a reset member is provided 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 can be a servo motor. The servo motor has a position feedback function, can achieve precise rotation control through the controller, and can set the reset position to achieve automatic reset after rotation. Servo motors are suitable for applications 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 a cylinder lifting mechanism, an electric screw lifting mechanism, a hydraulic lifting mechanism, or a chain or gear lifting mechanism.

[0069] Cylinder lifting mechanisms use air pressure to push a piston to achieve the desired lift. Cylinders offer advantages such as fast response, simple structure, and low cost, making them suitable for applications requiring high speed and precision.

[0070] The electric screw lift mechanism uses a motor to rotate the screw, which in turn moves the nut up and down, achieving lift height. This mechanism offers high precision and is suitable for applications requiring stable and precise control of lift position.

[0071] Hydraulic lifts utilize liquid pressure to propel a piston, achieving lift and lowering. Hydraulic systems are suitable for applications with heavy loads, offering high load capacity and stability, making them ideal for applications requiring heavy loads.

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

[0073] Working method of material 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 placement, the robot tilts and presses the plastic product downward against the mounting base 15, causing the receiving platform 14 to rotate via the rotator 13 and pull the reset member to deform to match the robot's tilt and downward pressure, allowing the plastic product to be fully placed in the mounting base 15 and locked into the retaining groove 151.

[0076] A3. After the plastic product is clamped in the slot 151, the robot releases the plastic product and moves away from the receiving mechanism 1. The receiving platform 14 returns 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 arrangement of rotating the receiving platform 14 using the rotator 13 allows the receiving platform 14 to adjust its angle as the robot arm tilts and presses downward, ensuring that the plastic product can be accurately placed into 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 portion of the plastic product, ensuring stability and accuracy in subsequent operations and avoiding shearing or grinding errors caused by 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 , which 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 pressing drive 161 is fixed to the receiving platform 14 and is used to drive the rotary actuator 162 to move up and down. The pressing drive 161 is a pneumatic cylinder or an electric cylinder.

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

[0085] Once the plastic product is secured in slot 151, the pressing driver 161 drives the rotary actuator 162 downward. Simultaneously, the rotary actuator 162 drives the pressing plate 163 to rotate over the plastic product. When the pressing driver 161 drives the rotary actuator 162 downward to a predetermined position, the pressing plate 163 contacts the plastic product, preventing it from separating from the fixing base 15 as the lifter 11 drives the lifting base 12 downward. This allows the pressing plate to precisely cover the plastic product, improving the flexibility and precision of its securing. This ensures that the plastic product remains stably secured during conveying, shearing, or polishing operations, enhancing overall processing accuracy.

[0086] This design reduces the movement error of plastic products during the 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 base 15 of this embodiment, and an opening 153 is provided on one side of the fixing base 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 clamp 24 , a pushing drive 25 , a shearing seat 26 and a shearing adjustment actuator 27 .

[0089] The transfer drive 21, transfer drive 23, and 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 drive 21 is arranged directly below the material receiving mechanism 1, and the conveying table 22 is fixed to the transfer drive 21. The transfer drive 21 is used to drive the conveying table 22 to slide between the transfer drive 23 and the material receiving mechanism 1, so that the plastic products can be stably and accurately transported from the material receiving mechanism 1 to the shearing mechanism 3, realizing automated conveying operations, reducing manual intervention, and improving production efficiency.

[0091] The transfer driver 23 is provided on 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 provided 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 provided 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 base 12 down to the same level as the conveyor platform 22. The fixed base 15 is suspended on the periphery of the conveyor platform 22. When the conveyor platform 22 is located in the middle hole 152, the plastic product is located above the conveyor platform 22.

[0097] B2. The lifter 11 drives the lift base 12 down to a position below the level of the conveyor platform 22. The plastic product is placed on the conveyor platform 22. The transfer driver 21 drives the conveyor platform 22 to slide away from the receiving mechanism 1 through the opening 153 of the fixed seat 15 and transports the plastic product on the conveyor platform 22 to a predetermined position near the transfer driver 23. The transfer mechanism 2 then receives the plastic product conveyed by the receiving mechanism 1.

[0098] B3. The visual camera captures an image of the plastic product's position and feeds it back to the master control system. The master control system processes the image to determine the plastic product's position in three-dimensional space. The master control system then controls the transfer driver 23 to drive the transfer fixture 24 toward the conveyor table 22. The transfer fixture 24 grips the plastic product carried on the conveyor 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 shear adjustment actuator 27 to drive the shear seat 26 to rotate to adjust the shearing point of the plastic product. The angle encoder monitors the angle change of the shear 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] A visual camera captures the three-dimensional position of the plastic product and feeds it back to the master control system, ensuring that the product maintains its accurate position during conveying and shearing. An angle encoder monitors the angle changes of the shear adjustment actuator 27 and provides real-time feedback to the master control system, enabling more precise adjustment of the shear point.

[0102] The combined design of the transfer driver 23 and the transfer fixture 24 makes the transfer process of the plastic product smoother and more 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 of the plastic product, coupled with feedback from an angle encoder, to achieve high-precision control of the shearing process. During the shear point adjustment process, a visual feedback system provides real-time monitoring, 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 drive 31 and a cutter 32. Two cutters 32 are fixed to the shearing drive 31 relative to each other. The shearing drive 31 drives the two cutters 32 toward or away from each other. When the shearing drive 31 drives the two cutters 32 toward each other, the shear point where the plastic product meets the sprue is cut. After the shear point where the plastic product meets the sprue is cut, the shearing drive 31 drives the two cutters 32 away from each other. This achieves efficient sprue shearing and ensures a smooth and precise 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 gripping manipulator 41, which can be a pneumatic or hydraulic cylinder gripping manipulator. By gripping the plastic product with the gripping manipulator 41, the transfer stability of the plastic product between shearing and polishing processes is effectively ensured, reducing processing errors caused by workpiece slippage or shifting, and improving the continuity and reliability of 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. This allows the master control system to optimize and adjust the shearing and polishing processes in real time based on the material characteristics, adapting to plastic products of different materials and improving 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 plastic product and the nozzle by the shearing mechanism 3 is as follows:

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

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

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

[0114] C4. The shearing driver 31 drives the two cutters 32 to move closer to each other according to the preset shearing force to cut the shear point where the plastic product and the nozzle are sheared.

[0115] The shearing mechanism 3 drives the shear adjustment actuator 27 and the shear seat 26 toward the shear drive 31 through the push drive 25, allowing the plastic product to accurately enter 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 gripping manipulator 41 in the material conveying mechanism 4 grips 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 precise 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 precisely controls the approach of the two cutters 32 based on a preset shear force, ensuring smooth separation at the shear point. Combined with material identification feedback, the shear force can be adjusted based on the hardness or thickness of the plastic product, avoiding unnecessary mechanical wear and improving 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, reducing processing defects caused by differences in material properties, improving the intelligence level and production efficiency of the equipment, and reducing the scrap rate.

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

[0121] Low hardness plastics (Shore A 40-60, 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 shear force. At the same time, it is necessary to avoid excessive shear force that may cause material deformation or burrs.

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

[0125] Shear strength: 100-200N

[0126] Shearing properties: Medium-hard plastics require moderate shearing force to ensure smooth shearing while maintaining a smooth cut surface. A greater shearing force helps prevent tearing or incomplete breaking of the plastic during cutting.

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

[0128] Shear strength: 200-400N

[0129] Shearing characteristics: For harder plastics, higher shear force can ensure clean and rapid cutting, avoiding incomplete cutting due to insufficient shear force. Especially when encountering reinforced materials, higher shear force 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 forces can be fine-tuned based on the hardness and thickness of the specific material. The master control system uses sensors to identify the material properties and automatically adjust the shear force.

[0134] Preferably, the shearing mechanism 3 further includes a movable actuator 33, which drives the shear actuator 31 toward the shearing seat 26, thereby facilitating the shear actuator 31 to drive the cutter 32 to cut the plastic product at the shear point where it meets the nozzle. The movable actuator 33 drives the shear actuator 31 away from the shearing seat 26 to avoid interference with the material conveying mechanism 4. The movable actuator 33 can be an electric actuator, a pneumatic actuator, or a hydraulic actuator. An electric actuator, such as an electric cylinder, a pneumatic actuator, such as an air cylinder, or a hydraulic actuator, such as a hydraulic cylinder.

[0135] like Figure 6 As shown, the material conveying mechanism 4 of this embodiment includes a turntable mechanism 42, a plurality of clamping manipulators 41, and the plurality of clamping manipulators 41 are arranged at intervals on the turntable mechanism 42, and the turntable mechanism 42 is respectively arranged at a material receiving station 421, a grinding station 422, a detection station 423 and a transfer station 424;

[0136] The turntable mechanism 42 is an intermittent splitting transmission mechanism, which combines conventional motors, transmission shafts, turntables, intermittent dividers and other components to achieve intermittent rotation of the turntable.

[0137] The sensor module includes a quality inspection vision camera;

[0138] The shearing mechanism 3 is arranged at the material receiving station 421, the grinding mechanism 5 is arranged at the grinding station 422, the quality inspection visual camera is arranged at the inspection station 423, the first material receiving mechanism 7 is arranged on one side of the transfer station 424, and the turntable mechanism 42 drives the clamping robot 41 to stop at the material receiving station 421, the grinding station 422, the inspection station 423 and the transfer station 424 in sequence.

[0139] When in use, the turntable mechanism 42 drives the clamping robot 41 to stop at the material receiving station 421, and the clamping robot 41 clamps the plastic product to facilitate cutting the water outlet of the plastic product. The turntable mechanism 42 drives the clamping robot 41 to stop at the polishing station 422, and the polishing mechanism 5 polishes the shearing protrusion, effectively improving the surface finish of the plastic product. The turntable mechanism 42 drives the clamping robot 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 inspects or evaluates the quality of the polishing of the plastic product, thereby improving the qualified rate of the plastic product, reducing the defective rate, and improving product quality. The turntable mechanism 42 drives the clamping robot 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 automated processes, manual intervention is reduced, significantly improving production speed and efficiency. The continuous rotation of the turntable mechanism 42 and the precise positioning of the gripping manipulator 41 ensure seamless connection between each workstation, shortening the production cycle and improving production efficiency.

[0141] Traditional manual production lines require a lot of manpower input, while this 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, it is possible to flexibly adapt to the production needs of different production scales and product types, 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 enhance 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. 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, thereby preventing the clamping manipulator 41 from interfering with the shearing mechanism 3 and the grinding mechanism 5, and allowing the turntable mechanism 42 to 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, thereby facilitating 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. The electric driver may be an electric cylinder, the pneumatic driver may be an air cylinder, and the hydraulic driver may be 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 provided at the other end of the fixing frame 51 ;

[0148] The end of the fixture 52 away from the mounting frame 51 is provided with an extended frame 521 for securing the plastic product, thereby restraining the plastic product. The end of the fixture 52 near the mounting frame 51 is provided with a grinding opening 522. The shearing point between the plastic product and the nozzle is exposed in the grinding opening 522. The grinding opening 522 facilitates grinding the shearing protrusion at the shearing point between the plastic product and the nozzle, and also protects other parts of the plastic product from being polished.

[0149] The polishing driver 54 drives the polishing head 53 to move along the polishing opening 522 to polish the shearing portion between the plastic product and the nozzle.

[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, and a conventional XY-axis driving mechanism such as a driving module that cooperates with a ball screw and a linear guide, a driving module that cooperates with a synchronous toothed belt and a linear guide, or a dual-motor driving module, enables the grinding driver 54 to drive 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 housing 531 , a sliding housing 532 , a telescopic driver 533 , a grinding actuator 534 and a grinding wheel 535 .

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

[0154] The fixed housing 531 is fixed to the grinding driver 54 and is slidably connected to the sliding housing 532 , so that the grinding head 53 is connected to the grinding driver 54 , making it easier for the grinding driver 54 to drive 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 accuracy and efficiency of grinding.

[0156] The telescopic actuator 533 is fixed to the fixed housing 531 and is used to drive the sliding housing 532 to slide along the fixed housing 531. This can precisely control the sliding movement of the sliding housing 532 within the fixed housing 531, thereby achieving fine adjustment of the position of the grinding wheel 535. This design helps achieve finer control and more uniform grinding results during the grinding process.

[0157] The grinding actuator 534 secures the sliding housing 532 and drives the grinding wheel 535. The grinding actuator 534 is directly secured to the sliding housing 532 and drives the grinding wheel 535. This direct drive reduces power transmission losses, improves energy efficiency, and makes the grinding process more efficient. The shearing projections are ground by the rotating grinding wheel 535 contacting them.

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

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

[0160] Preferably, the sliding housing 532 is provided with a slide bar 5321, which is hingedly connected to the sliding housing 532. A guide slider 5311 and a limit block 5312 are provided in the fixed housing 531. The slide bar 5321 slides along the guide slider 5311, thereby achieving a sliding connection between the fixed housing 531 and the sliding housing 532. The limit block 5312 is configured to interfere with the slide bar 5321. By interfering with the slide bar 5321, the limit block 5312 limits the position of the guide slider 5311, thereby controlling the sliding travel of the sliding housing 532.

[0161] like Figure 9 Specifically, the articulated arm 536 includes a first connecting base 5361, a second connecting base 5362, a cross-rotating member 5363, and a telescopic member 5364. The first connecting base 5361 is fixedly connected to the fixed frame 51, and the second connecting base 5362 is fixedly connected to the sliding housing 532. There are two cross-rotating members 5363, and the ends of the telescopic member 5364 are respectively hinged to the first connecting base 5361 and the second connecting base 5362 via the cross-rotating member 5363. This achieves a hinged connection between one end of the articulated arm 536 and the sliding housing 532, while 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. This ensures that the sliding housing 532 and the fixed frame 51 are hingedly connected via the hinged arm 536, with a certain degree of telescopic margin, making the sliding housing 532 more flexible and stable in its movement along the fixed frame 51.

[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, middle edging and 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 shear point between the plastic product and the nozzle.

[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 , through which grinding debris is collected, 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 exerted 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 second torque sensor detects in real time the pressure applied by the grinding wheel 535 on the plastic product, and the friction coefficient tester detects in real time the friction coefficient between the grinding wheel 535 and the plastic product, and feeds back to the master control system.

[0177] When in use, the master control system uses ultrasonic sensors to identify the material properties of plastic products through specific wavelengths or spectral reflections. The master control system adjusts the polishing pressure P(t) of the telescopic driver 533 based on the hardness of the plastic product material and the formula for the polishing pressure P(t), and adjusts the polishing speed V(t) of the polishing actuator 534 based on the formula for the polishing speed V(t).

[0178] A second torque sensor and a friction coefficient tester measure the pressure and friction coefficient of the grinding wheel on the plastic part in real time, dynamically adjusting the grinding pressure and speed based on the hardness of the plastic material. This real-time feedback and adjustment mechanism ensures the accuracy and efficiency of the grinding process, avoiding over- or under-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 medium hardness plastics (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] A camera module captures images of the shearing protrusions and uses image recognition technology to capture key points and generate the shortest possible sanding path. This approach not only reduces sanding time but also improves sanding accuracy and avoids unnecessary material removal, thus 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 for 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 the adjustment factors for depth and number of times.

[0195] d ini The initial grinding depth ranges from 0.1 mm to 1.0 mm. In this embodiment, d ini =0.5mm example.

[0196] Q std The standard smoothness range is between 0 and 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 in real time by the camera module. 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 driver 533 and the number of times N(t) that the polishing driver 54 moves back for polishing based on the polishing depth d(t) adjustment formula.

[0199] Based on the real-time feedback from the camera module about the shear bumps, the master control system dynamically assesses the surface finish after polishing and adjusts the polishing depth and frequency accordingly. This intelligent adjustment mechanism ensures that the ideal surface quality is achieved regardless of the initial state of the plastic product, improving overall product quality and consistency.

[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- or under-grinding, thereby lowering production costs.

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