Description

Technical Field

[0001] This invention relates to the field of independent spring manufacturing technology, and in particular to an integrated production line for independent spring processing and automatic packaging. Background Technology

[0002] Traditional independent spring production lines mostly adopt segmented, manual-assisted, or semi-automated production modes. Springs rolled by spring machines need to be sorted and fed by humans or simple mechanisms, and then sent into a tempering furnace for heat treatment by independent conveying equipment. After tempering, the springs are transferred to independent packaging equipment for packaging by humans or a separate handling mechanism. This production method has many technical defects.

[0003] Firstly, the equipment in each process is independent, resulting in poor automation and continuity. Springs require multiple transfers between loading, tempering, unloading, discharging, and packaging, making the production process cumbersome, time-consuming, and prone to deformation and damage, affecting product qualification rates. Secondly, the loading process in tempering lacks orderly and automated mechanisms, leading to problems such as spring stacking, jamming, and chaotic posture, preventing stable and continuous entry into tempering and subsequent workstations, resulting in insufficient production line stability. Thirdly, the handling mechanisms lack versatility and adaptability. Traditional clamps are mostly rigid structures, making it difficult to adapt to the flexible clamping requirements of springs. Furthermore, their multi-station handling and pitch adjustment capabilities are insufficient, failing to simultaneously meet the requirements of multiple actions such as tempering loading, tempering unloading, discharging, and transfer packaging. Overall, traditional production lines have low integration, large footprint, and high reliance on manual labor, resulting in low production efficiency, high labor costs, and low product quality consistency, making it difficult to achieve efficient and stable automated continuous production.

[0004] Therefore, there is an urgent need for an integrated production line that combines independent spring processing and automated packaging to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the background art and provide an integrated production line for independent spring processing and automatic packaging.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: An integrated production line for independent spring processing and automatic packaging includes a conveyor belt and a combing device, a handling device, a tempering furnace, a material discharge detection device, and a packaging device arranged sequentially on the conveyor belt. The output end of the tempering furnace is also provided with a discharge device, which is located outside the conveyor belt. A packaging detection device is provided above the packaging device.

[0007] Preferably, the conveyor belt includes a feeding conveyor section and a discharging conveyor section, which are respectively fixed on both sides of the tempering furnace. Conveying brackets, which are V-shaped, are fixedly arranged on both the feeding and discharging conveyor sections. The feeding conveyor section transports the rolled springs to the input end of the tempering furnace, while the discharging conveyor section receives the tempered springs and transports them to the packaging device. The V-shaped conveying brackets provide stable support and limit for the springs, preventing them from rolling or shifting during transport. Combined with the conveying action of the conveyor belt, this ensures smooth transport of the springs between various process stations.

[0008] Preferably, the feeding conveying section is equipped with a lifting assembly, which includes a lifting arm, a lifting telescopic rod, a lifting connecting block, and a lifting driver for driving the lifting connecting block. Two lifting arms are located on either side of the feeding conveying section. The lifting driver is fixedly installed below the feeding conveying section. The lifting connecting block is fixedly installed on the output shaft of the lifting driver and located between the lower parts of the two lifting arms. The fixed ends of the lifting telescopic rod are respectively fixed on both sides of the lifting connecting block. The telescopic ends of the lifting telescopic rod are fixedly connected to the lifting arms. A lifting support groove is fixedly provided on the top of the lifting arm. V-groove; When the spring advances with the feeding conveyor section to the lifting assembly, the lifting telescopic rod retracts inward until the lifting arm is close to both sides of the feeding conveyor section. At the same time, the lifting driver drives the lifting connecting block to lift upward until the bottom height of the lifting tray exceeds the top height of the feeding conveyor section, thus lifting the spring placed on the conveyor bracket upward, making it easier for the handling device to grab the spring. After the handling device completes the material removal, the lifting assembly falls back to its original position. This structure achieves precise alignment and smooth transfer between the spring and the input end of the tempering furnace, avoiding manual lifting and rigid collisions, and improving the consistency of the feeding posture and the stability of the process connection.

[0009] Preferably, the combing device includes a combing track, an upper guide hopper, a lower guide hopper, and an intermittent material dropping assembly. The combing track is located at the starting end of the feeding conveyor section. The upper and lower guide hoppers are fixedly mounted on the feeding conveyor section, with the upper guide hopper positioned above the lower guide hopper. The intermittent material dropping assembly includes a material dropping guide rail, a material dropping slider, a material dropping baffle, and a material dropping sensor. The material dropping guide rail is fixedly mounted on the feeding conveyor section and located behind the lower guide hopper. The material dropping slider is slidably mounted on the material dropping guide rail. The material dropping baffle is fixedly mounted in front of the material dropping slider and located between the upper and lower guide hoppers. The material dropping sensor is fixedly mounted on the material dropping baffle. A spring is formed... In spring production, the coiled springs fall from the output end of the spring machine onto the combing conveyor belt and move forward until they fall into the upper guide hopper. The material drop sensor located at the outlet below the upper guide hopper detects the spring falling in, and the material drop slider drives the material drop baffle to slide backward until the spring falls from the upper guide hopper through the lower guide hopper into the conveyor bracket of the feeding section. The intermittent material drop assembly detects the material status through the material drop sensor to realize intermittent material blocking and release, controlling the springs to fall independently and orderly into the conveyor bracket. This solves the problems of traditional material stacking, jamming, and chaotic posture from the source, realizing automated, intermittent, and orderly spring feeding, and improving the stability and continuous operation capability of the production line.

[0010] Preferably, the conveying device includes a loading conveying device and a unloading conveying device. Both the loading and unloading conveying devices include a three-axis motion assembly and a flexible gripper assembly. The three-axis motion assembly of the loading conveying device is fixedly mounted above the input end of the tempering furnace and the loading conveying section. The three-axis motion assembly of the unloading conveying device is fixedly mounted above the output end of the tempering furnace, the unloading conveying section, and the discharge device. The flexible gripper assemblies are slidably mounted on the three-axis motion assembly. The loading conveying device grabs the springs lifted by the lifting assembly and transfers them to the input end of the tempering furnace. The unloading conveying device grabs the springs after tempering and transfers them to the unloading conveying section or the discharge device. The three-axis motion assembly enables the flexible gripper assembly to move flexibly and accurately in space. The flexible gripper assembly flexibly clamps the springs. The conveying device replaces traditional manual or rigid conveying methods, reduces deformation and collisions during spring transfer, improves conveying efficiency and workstation docking accuracy, and enhances the automated continuous operation capability of the production line.

[0011] Preferably, the flexible gripper assembly includes a gripper fixing slider, a gripper drive mounting base, a gripper turntable, a gripper mounting base, flexible grippers, and a gripper rotation driver for driving the gripper turntable. The gripper fixing slider is slidably mounted on the three-axis motion assembly, the gripper drive mounting base is fixedly mounted on the gripper fixing slider, the gripper rotation driver is fixedly mounted on the gripper drive mounting base, the gripper turntable is rotatably mounted below the gripper drive mounting base and fixedly connected to the output shaft of the gripper rotation driver, and the gripper mounting base is fixedly mounted below the gripper turntable. A plurality of flexible grippers are also included. The flexible jaws are fixedly mounted on the jaw mounting base. When a spring needs to be moved, the three-axis motion assembly drives the jaw fixing slider to move to the corresponding position. The jaw turntable adjusts its rotation angle according to the spring's posture. Several flexible jaws adjust their opening angle according to the spring's size. The flexible jaws adopt a symmetrical opening and closing structure. The clamping section is a concave arc-shaped structure adapted to the outer contour of the independent spring. The bottom is provided with an inwardly protruding step. When the flexible jaws are closed, their arc-shaped clamping surface fits against the spring surface. The bottom step prevents the spring from falling off. The flexible jaw assembly realizes synchronous, precise, and stable clamping of multiple springs.

[0012] Preferably, the flexible gripper assembly of the material handling device further includes a variable pitch guide rail and a gripper variable pitch block. The variable pitch guide rail is fixedly mounted on the gripper mounting base, and a plurality of gripper variable pitch blocks are slidably mounted on the variable pitch guide rail. The flexible gripper is fixedly mounted on the gripper variable pitch blocks. The variable pitch guide rail and the gripper variable pitch blocks can flexibly adjust the clamping distance according to the station spacing of the tempering furnace, the material conveying section and the discharge device, and the spring size, so as to realize the precise transfer of springs of multiple stations and multiple specifications, improve the adaptability and flexibility of material handling, and ensure the smooth connection between the material handling stage and the subsequent processes.

[0013] Preferably, the tempering furnace includes a processing track and processing brackets. The processing track is rotatably disposed inside the tempering furnace, and the processing bracket array is fixedly disposed on the processing track. The processing brackets are V-shaped, and several grouping partitions are fixedly disposed on the processing brackets. The V-shaped processing brackets prevent the springs from rolling and shifting during the tempering process. The grouping partitions divide each bracket into multiple independent workstations, ensuring that multiple batches of springs do not come into contact, collide, or stick together when tempering simultaneously. At the same time, fixed pick-up and drop-off points are formed, laying the foundation for automated handling and adapting to the automation requirements of integrated production lines.

[0014] The discharge device provides an independent discharge temporary storage station for the tempered springs, avoiding the accumulation of springs caused by the continuous output of the tempering furnace when the downstream packaging device stops, maintaining the continuity of the tempering process, reducing the risk of production interruption, and ensuring the stable operation of the integrated production line.

[0015] Preferably, the packaging device includes a receiving roller, a transfer roller, a forming roller, a hot press roller, and a guide traction roller group arranged sequentially along the conveying direction, as well as an upper film unwinding roller and a lower film unwinding roller. The receiving roller is rotatably positioned below the end of the feeding conveying section, the upper film unwinding roller is rotatably positioned above the forming roller, and the lower film unwinding roller is rotatably positioned below the forming roller. Anti-detachment blocks are fixedly provided above the junction of the receiving roller and the transfer roller, and below the transfer roller, respectively. A material-pushing wedge is fixedly provided above the junction of the forming roller and the transfer roller. Both the receiving roller and the transfer roller have interlocking material-pushing protrusions. The forming roller has a receiving groove, and the hot press roller has a sealing protrusion. A spring falls from the end of the feeding conveying section into the groove formed by the material-pushing protrusion of the receiving roller and rotates with the counterclockwise rotating receiving roller. The spring is pushed into the transfer roller by the material-pushing protrusion under the limiting position of the stop block. The transfer roller rotates clockwise, and the spring rotates with the transfer roller to the front of the forming roller under the limiting position of the anti-detachment stop block. The lower packaging film is rolled onto the surface of the forming roller by the lower film unwinding roller. The spring is pushed into the receiving groove with the lower packaging film by the material-pushing wedge. The forming roller rotates counterclockwise, driving the spring forward. The upper packaging film is rolled onto the surface of the spring by the upper film unwinding roller. The hot press roller rotates clockwise and presses the upper and lower packaging films of the spring together through the sealing protrusion, completing the packaging of the independent spring. Finally, it is placed into the packaging box by the guide traction roller group. The guide traction roller group has a tensioning function, which can apply tension to the packaging bag to keep the packaging bag flat and stable and prevent the spring from falling out of the bag. The packaging device realizes fully automated continuous operation of spring packaging.

[0016] Preferably, both the feeding detection device and the packaging detection device include detection cameras. The detection camera of the feeding detection device is fixedly installed above the feeding conveyor section, and the detection camera of the packaging detection device is fixedly installed above the guide traction roller group and located downstream of the hot pressing roller. The feeding detection device detects whether the tempered springs are stacked and whether their posture is normal. The packaging detection device detects whether the packaged springs are stacked and whether their size and spacing are correct, thus preventing unqualified products from flowing into the next process or leaving the factory, effectively improving the product quality pass rate. The camera replaces traditional manual inspection, reducing reliance on manual labor and detection errors.

[0017] In summary, the present invention has the following beneficial effects: 1. This invention integrates core components such as combing device, handling device, tempering furnace, discharging device, feeding detection device, and packaging device onto a single production line. Relying on the conveyor belt, it achieves seamless connection between various processes, breaking the traditional segmented and independent production mode of production lines.

[0025] according to Figure 1 , Figure 5 As shown, the conveying device 3 includes a loading conveying device 301 and a unloading conveying device 302. Both the loading conveying device 301 and the unloading conveying device 302 include a three-axis motion component 31 and a flexible claw component 32. The three-axis motion component 31 of the loading conveying device 301 is fixedly mounted above the input end of the tempering furnace 4 and the loading conveying section 101.

The receiving roller 61 is rotatably positioned below the end of the unloading conveying section 102. The upper film unwinding roller 661 is rotatably positioned above the forming roller 63, and the lower film unwinding roller 662 is rotatably positioned below the forming roller 63. Anti-detachment blocks 67 are fixedly provided above the junction of the receiving roller 61 and the transfer roller 62, and below the transfer roller 62, respectively. A material-feeding wedge 68 is fixedly provided. Both the receiving roller 61 and the transfer roller 62 are provided with mutually meshing material-feeding protrusions 69. The forming roller 63 is provided with a receiving groove 631, and the hot pressing roller 64 is provided with a sealing protrusion 641.

The bottom of the material-feeding wedge is provided with a wedge tooth 682. The wedge tooth 682 blocks the spring located between the material-feeding protrusions 69 of the transfer roller 62 and forces the spring to disengage from the transfer roller 62, so that the spring falls into the receiving groove 631 covered with the lower packaging film under the guidance of gravity and the tooth surface of the wedge tooth 682.

[0030] according to Figure 8As shown, both the feeding detection device 701 and the packaging detection device 702 include a detection camera 71.

[0031] Working principle: According to Figures 1-10As shown, the spring falls from the output end of the spring machine into the combing conveyor 21, and moves forward with the combing conveyor 21 until it falls into the upper guide hopper 22. The material drop sensor 28 detects that material has entered, and the material drop baffle 27 slides backward with the material drop slider 26 until the spring falls down, and falls into the conveying bracket 11 of the feeding conveyor section 101 through the lower guide hopper 23, thus completing the material combing. The spring moves forward with the feeding conveyor section 101, and is arranged in groups according to the number of lifting trays 17. When a group of springs is in place, the lifting driver 16 drives the lifting arm 13 to move inward and upward until the lifting tray 17 lifts the spring away from the conveying bracket 11. The three-axis motion component 31 of the feeding and conveying device 301 drives the flexible claw component 32 to move above the lifting tray 17, and the claw turntable 35 drives the flexible claw 37 to align with the lower part. After the spring is released, the three-axis motion assembly 31 drives the flexible jaw 37 downwards until it contacts the spring. The flexible jaw 37 closes to grasp the spring and moves to above the input end of the tempering furnace 4. The jaw turntable 35 drives the flexible jaw 37 to align with the processing bracket 42 below. The flexible jaw 37 moves downwards until the spring contacts the processing bracket 42. The flexible jaw 37 opens to release the spring. The three-axis motion assembly 31 drives the flexible jaw assembly 32 back above the lifting tray 17 to wait for the next set of springs to be positioned. The tempering loading is completed. The number of groups formed by the grouping partition 43 constitutes a batch. After a batch of springs is placed, the processing track 41 drives the springs forward into the processing area for tempering. After processing, the processing track 41 drives the springs forward out of the processing area. The tempering is completed. The three-axis motion component 31 of the material handling device 302 drives the flexible gripper component 32 to move. The flexible gripper 37 grabs the processed spring and places it into the conveyor bracket 11 of the unloading conveyor section 102. When the upstream processing efficiency is higher than the downstream packaging efficiency, the unloading conveyor 302 places the processed spring into the discharge device 5 for temporary storage. After the packaging device 6 returns to normal, the temporarily stored spring is placed into the unloading conveyor section 102, and the tempering unloading is completed. The spring moves forward with the unloading conveyor section 102. The detection camera 71 of the unloading detection device 701 detects the status of the spring. If the detection is abnormal, the abnormal spring is manually removed. If the detection is passed, the spring continues to move forward, and the online spring tempering detection is completed. At the end of the unloading conveyor section 102, the spring falls into the groove formed by the feeding protrusion 69 of the receiving roller 61. As the receiving roller 61 rotates, the material-pushing protrusion 69 of the transfer roller 62 pushes the spring into it and continues to drive the spring forward. The lower film unwinding roller 662 rolls the lower packaging film onto the surface of the forming roller 63. The spring is pushed into the receiving groove 631 containing the lower packaging film by the material-pushing wedge 68 and rotates with the forming roller 63. The upper film unwinding roller 661 rolls the upper packaging film onto the surface of the spring. The forming roller 63 continues to rotate until the sealing protrusion 641 of the hot press roller 64 presses the upper and lower packaging films wrapping the spring together. The guide traction roller group 65 pulls the packaged spring forward. The detection camera 71 of the packaging detection device 702 detects the status of the spring inside the packaging. If the detection is abnormal, the abnormal spring is removed manually. If the detection is passed, the spring continues to move forward until it is put into the packaging box, and the spring packaging is completed.
