Description

Technical Field

[0001] The present invention relates to the technical field of feeding and processing equipment, and in particular to a sorting and processing device for special-shaped springs. Background Art

[0002] A scroll spring (or coiled spring) is a common type of spring, mainly used for storing and releasing mechanical energy. It is usually constructed by winding a metal strip into a certain curvature. The design of the scroll spring enables it to rebound under axial pressure and is widely used in various mechanical equipment, such as automatic doors, toys, clocks, and various motor equipment.

[0003] During the cold working process, internal stress will be generated in the metal material, which will accelerate the deformation or aging of the spring during use. In order to help the spring homogenize the internal stress, reduce the risk of deformation caused by stress release, and make its elasticity and shape more stable, it is necessary to perform stress relief treatment on the spring.

[0004] Existing spring stress relief devices usually require manual sorting and ranking of springs. Since a large number of springs are produced and processed at one time, manual sorting requires a large amount of labor input. Especially during the peak production period, the number of workers often fails to meet the demand, resulting in a reduction in the operating efficiency of the production line. Moreover, long-term repetitive sorting work will cause worker fatigue, affecting their work efficiency and accuracy, and increasing the risk of sorting errors. Therefore, there is room for improvement. Summary of the Invention

[0005] In order to solve the above-mentioned technical problems, the present invention provides a sorting and processing device for special-shaped springs to solve the technical problem that existing spring processing equipment requires manual sorting and ranking, resulting in low spring processing efficiency.

[0006] The present invention is achieved through the following technical solutions: A sorting and processing device for special-shaped springs includes a sorting device, a stretching device, and a control terminal. A feeding track is provided between the sorting device and the stretching device. The sorting device includes a spiral channel assembly, a vibration motor, and an anti-piling-up component. The vibration motor is used to vibrate the spiral channel assembly, and the spring is sorted and conveyed upward along the spiral channel assembly to the feeding track. The feeding track conveys the spring to the stretching device. The anti-piling-up component is arranged at the central position of the spiral channel assembly to prevent the springs in the spiral channel assembly from piling up. The stretching device is used to stretch the spring to release stress. Both the sorting device and the stretching device are communicatively connected to the control terminal. Among them, the spring includes a body and a hanging ear part, and the body and the hanging ear part are integrally formed.

[0007] Preferably, the anti-piling-up component includes a turntable and a partition. The turntable is arranged at the central position of the spiral channel component. The partitions are arranged on the turntable at equal angles. The height of the partition is less than the diameter of the body. The feeding device randomly feeds the springs into the turntable.

[0008] Preferably, the turntable is arranged in a conical structure with a higher middle part and lower peripheral parts.

[0009] Preferably, the spiral channel component includes a first direction adjustment component. The first direction adjustment component is connected to the feeding guide rail. The first direction adjustment component includes a first baffle plate and a second baffle plate. A material guide groove is arranged between the first baffle plate and the second baffle plate. The height of the material guide groove is greater than the diameter of the body and less than the height of the hanging ear part. The first baffle plate is inclined. The edge of the first baffle plate far from the center of the anti-piling-up component is higher than the edge of the end close to the center of the anti-piling-up component.

[0010] Preferably, the spiral channel component includes a second direction adjustment component. The second direction adjustment component is connected to the end of the first direction adjustment component far from the feeding track. The second direction adjustment component includes a first transition plate, a second transition plate, and a third transition plate. The first transition plate, the second transition plate, and the third transition plate are connected in sequence. The width of the vertical plate of the second transition plate is less than the width of the horizontal plate of the first transition plate. One end of the vertical plate of the second transition plate is tangent to the horizontal plate of the first transition plate. The other end of the vertical plate of the second transition plate is tangent to the vertical plate of the third transition plate. The height of the horizontal plate of the third transition plate is lower than the height of the horizontal plate of the second transition plate.

[0011] Preferably, the sorting and processing device further includes a vision detection device. The vision detection device includes a camera and an image processing unit. The camera is installed above the spiral channel component and is used to capture the distribution image of the springs. The image processing unit is used to analyze the spring density and distribution in the image, calculate the congestion degree of the springs. The vision detection device is communicatively connected to the control terminal. The control terminal calculates the optimal vibration frequency according to the received spring congestion degree data and through a preset algorithm.

[0012] Preferably, the vibration motor is communicatively connected to the control terminal. The control terminal adjusts the vibration frequency of the vibration motor. When the congestion degree of the springs on the spiral channel component is relatively high, the control terminal issues an instruction to reduce the vibration frequency. When the congestion degree of the springs on the spiral channel component is relatively low, the control terminal issues an instruction to increase the vibration frequency.

[0013] Preferably, the stretching device includes a clamping assembly and a stretching assembly. The clamping assembly is used to fix the spring. The stretching assembly is fixed to the hanging ear part and stretches the hanging ear part. The stretching assembly stretches each group of hanging ear parts twice.

[0016] The beneficial effects of the present invention are as follows: 1. Through the sorting device, the special-shaped springs can be accurately sorted through the spiral channel assembly. The automatic sorting device not only improves the conveying speed of the springs, but also significantly improves the overall processing efficiency. The stretching device can efficiently release the stress of the springs, further improving the product quality. The setting of the anti-piling component ensures that the springs flow smoothly in the spiral channel assembly, preventing blockage caused by piling, and can effectively control the inlet and outlet speed of the springs, reasonably distribute the material flow in the channel, and thus improve the sorting efficiency of the springs. 2. Through the combined design of the turntable, partition board and weighing sensor, the problems of overlapping, piling and blockage of the springs during the conveying process are effectively solved. The conical structure of the turntable makes the springs flow naturally towards the edge. The partition board cooperates with the weighing sensor to monitor the spring distribution in real time and adjust the rotation speed of the turntable to ensure the uniform distribution of the springs. 3. The first-direction adjustment component and the second-direction adjustment component in the spiral channel assembly, through the design of the baffle plate and the transition plate, make the springs arranged in the same direction and adjust the posture, ensuring the smoothness and direction consistency of the conveying. The visual detection device monitors the spring distribution in real time, and the control terminal dynamically adjusts the vibration frequency to further improve the conveying efficiency. In addition, the guide grooves and sensors on the feeding track ensure the precise positioning and stable conveying of the springs, reducing the risk of deviation and misalignment. The overall design significantly improves the automation level and production efficiency of the spring sorting process, reduces the need for manual intervention, and ensures the continuity and stability of production.

[0028] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined inventive purpose, the following will, with reference to the drawings and preferred embodiments, elaborate in detail on the specific embodiments, structures, features and their effects according to the present invention.

[0029] Please refer to Figures 1-6, A special-shaped spring 1 sorting and processing device, including a sorting device 2, a stretching device 3 and a control terminal. A feeding track 4 is arranged between the sorting device 2 and the stretching device 3. The sorting device 2 includes a spiral channel assembly 21, a vibration motor and an anti-piling-up assembly 22. The vibration motor is used to vibrate the spiral channel assembly 21. The spring 1 is sorted and conveyed upward along the spiral channel assembly 21 to the feeding track. The feeding track 4 conveys the spring 1 to the stretching device 3. The anti-piling-up assembly 22 is arranged at the central position of the spiral channel assembly 21 to prevent the spring 1 in the spiral channel assembly 21 from piling up; the stretching device 3 is used to stretch the spring 1 to release stress. Both the sorting device 2 and the stretching device 3 are communicatively connected to the control terminal. Among them, the spring 1 includes a body 11 and a hanging ear 12, and the body 11 and the hanging ear 12 are integrally formed.

[0030] The sorting device 2 can accurately sort the special-shaped spring 1 through the spiral channel assembly 21. By applying the drive of the vibration motor to the spiral channel assembly 21, the spring 1 can move orderly along the preset path, thus avoiding the dislocation and crossing of a single spring 1 during transportation, and ensuring its stability and accuracy during the filtering and sorting process; in the whole production process, the automatic sorting device 2 not only improves the conveying speed of the spring 1, but also greatly reduces the complexity of manual operation, reducing human errors. The realization of this automation makes the production line more efficient, able to complete more production tasks in a shorter time, and significantly improves the overall processing efficiency; the production and processing efficiency of the spring 1 is highly related to the smoothness of its sorting and conveying process. By combining the sorting device 2 with the stretching device 3, it is ensured that the spring 1 is in a good sorted state when it is conveyed to the stretching device 3. The stretching device 3 can efficiently release the stress of the spring 1, further improving the product quality; more importantly, the introduction of the control terminal enables the whole equipment to operate intelligently and automatically, real-time monitoring the status of each link, ensuring that each process can be carried out under the optimal conditions. This information-based management not only helps to improve efficiency, but also provides data support for subsequent production scheduling, further enhancing the operation flexibility.

[0031] The setting of the anti-piling-up assembly 22 is particularly important. Its core function is to ensure that the spring 1 flows smoothly in the spiral channel assembly 21 and prevent blockage caused by piling up. The existence of this assembly can effectively reduce the failure rate of the sorting device 2, avoid long-term downtime, and thus ensure the continuity of the production line; in actual operation, if the spring 1 appears piling up, it is very likely to cause material blockage, making the whole sorting system stagnate and having a negative impact on the production progress. By using the anti-piling-up assembly 22, the entry and exit speed of the spring 1 can be effectively controlled, and the material flow in the channel can be reasonably distributed, thereby improving the sorting efficiency of the spring 1. At the same time, the intervention required by the operator is reduced, further improving the automation level.

[0032] In order to separate each spring 1, reduce the probability of spring 1 overlapping and collapsing, and based on this, reduce the accumulation and mixing of spring 1 on the spiral channel assembly 21, and reduce the conveying stagnation or the dropping of spring 1 caused by stacking. In one embodiment, the anti-piling component 22 includes a turntable 221 and a partition 222. The turntable 221 is arranged at the central position of the spiral channel assembly 21, and the partitions 222 are arranged on the turntable 221 at equal angles. The height of the partition 222 is less than the diameter of the body 11. The feeding device 5 feeds the springs 1 into the turntable 221 in a disorderly manner. The setting of the turntable 221 enables the springs 1 to be evenly distributed in the spiral channel system, solving the problems of coincidence and accumulation caused by the disorderly feeding of the springs 1 originally. Under the action of the vibration motor, the turntable 221 can combine the self-movement of the spring 1 with the rotation of the turntable 221, so that each spring 1 can be separated by itself and evenly laid on the turntable 221. This design effectively reduces the probability of spring 1 overlapping and collapsing, ensuring that each spring 1 can smoothly enter the spiral channel assembly 21; by reducing the accumulation and mixing of spring 1 on the turntable 221, the equipment can reduce the conveying stagnation caused by stacking. This continuous and stable feeding behavior improves the operation efficiency and stability of the spiral channel assembly 21, providing a self-regulating solution for the equipment.

[0033] At the same time, weighing sensors 6 can be evenly distributed on the partition 222. The weighing sensors 6 are communicatively connected to the control terminal. The weighing sensors 6 are used to weigh the weight of the springs 1 on the turntable 221 between two adjacent partitions 222 and feedback the weight data of each partition 222 to the control terminal. The control terminal infers the number of springs 1 on the turntable 221 between two adjacent partitions 222 based on the obtained weight data, thereby adjusting the rotation speed of the turntable 221, and further controlling the feeding amount of the feeding device 5 on different turntables 221, ensuring that the springs 1 on the turntable 221 are evenly laid, and further ensuring the smooth and efficient conveying of the springs 1; the function of each sensor 6 is to monitor the weight of the springs 1 between two adjacent partitions 222 in the turntable 221 in real time. This weight data not only reflects the number of springs 1 on each partition 222, but also provides data support for the decision-making of the control terminal; through communication with the control terminal, the weighing sensors 6 can feedback the collected data to the system, allowing the control terminal to analyze the number and distribution of the springs 1. Based on these data, the system can intelligently adjust the rotation speed of the turntable 221 and optimize the feeding amount of the springs 1. At this time, the adjustment of the rotation speed ensures that the springs 1 can be evenly distributed on the turntable 221, further improving the efficiency and stability of the conveying.

[0034] Through the above two design elements, the conveying process of spring 1 becomes more efficient and stable. While providing uniform feeding, the turntable 221 ensures the preparation state of spring 1 before it enters the spiral channel assembly 21, avoiding jamming and conveying problems caused by uneven numbers of spring 1; this control mechanism greatly improves the production coherence, enabling spring 1 to be sorted and processed at a stable speed and high frequency. Combined with dynamic weighing feedback, the system can respond in real time and maintain the optimal production state, ensuring the efficient operation of the processing line; the anti-piling-up assembly 22 integrating the turntable 221, the partition 222 and the weighing sensor 6 significantly improves the automation level and production efficiency of spring 1 sorting and processing, reducing the downtime caused by operation errors or equipment failures. This not only ensures the stability of output, but also optimizes the production process, reduces the need for manual intervention, thus saving time and costs.

[0035] To avoid the phenomenon of spring 1 concentrating and piling up in the middle of the turntable 221 and ensure the continuous and efficient operation of the system, based on this, in one embodiment, the turntable 221 is set as a conical structure with a higher middle and lower periphery. The center of the conical turntable 221 is higher and the periphery is lower. This design enables spring 1 to flow naturally to the outside under the action of gravity. When spring 1 is fed onto the turntable 221, due to the influence of gravity, spring 1 will first slide down to the edge area of the turntable 221, avoiding the phenomenon of spring 1 concentrating and piling up in the middle. This guidance of natural flow ensures that each spring 1 can effectively approach the edge, providing favorable conditions for subsequent conveying; if the turntable 221 is flat, spring 1 may be stacked or clamped together, resulting in the inability to be smoothly conveyed to the spiral channel assembly 21. After being designed into a cone, spring 1 is guided to the edge, greatly reducing the probability of spring 1 overlapping and piling up. This design of reducing piling can effectively avoid jamming problems in the subsequent feeding process and ensure the continuous and efficient operation of the system; the conical design enables spring 1 to be more easily transferred from the turntable 221 to the spiral channel assembly 21. Since the edge of the turntable 221 is lower, spring 1 only needs a smaller inclined plane when rotating to smoothly slide towards the entrance of the spiral channel. Compared with the planar structure, this design greatly improves the conveying efficiency of spring 1 and reduces delays and errors caused by the need for a higher angle or a complex transfer path; the design of the conical structure also improves the utilization efficiency of the turntable 221. By promoting the uniform distribution of spring 1 on the turntable 221, this design can not only improve the working efficiency of the turntable 221, but also avoid uneven wear caused by uneven material distribution.

[0036] In order to arrange the springs 1 in the same direction and improve the sorting efficiency of the springs 1, based on this, in one embodiment, the spiral channel assembly 21 includes a first direction adjustment component 211. The first direction adjustment component 211 is connected to the feeding guide rail. The first direction adjustment component includes a first baffle plate 2111 and a second baffle plate 2112. A material guiding groove 2113 is provided between the first baffle plate 2111 and the second baffle plate 2112. The height of the material guiding groove 2113 is greater than the diameter of the body 11 of the spring 1 and less than the height of the hanging ear portion 12 at the same time. The first baffle plate 2111 is inclined. The edge of the first baffle plate 2111 far from the center of the anti-piling-up component 22 is higher than the edge of the end close to the center of the anti-piling-up component 22. After the spring 1 is conveyed to the first direction adjustment component 211, due to the fact that the edge of the first baffle plate 2111 far from the center of the anti-piling-up component 22 is higher than the edge of the end close to the center of the anti-piling-up component 22, under the action of gravity, the body 11 slides into the material guiding groove 2113. Since the height of the material guiding groove 2113 is less than the height of the hanging ear portion 12, the hanging ear portion 12 is caught by the second baffle plate 2112, so that the springs 1 are arranged in the same direction, and the springs 1 are orderly conveyed into the feeding guide rail.

[0037] The height of the material guiding groove 2113 is designed to be greater than the diameter of the body 11 of the spring 1 but less than the height of the hanging ear portion 12, so that the hanging ear portion 12 of the spring 1 is always caught on the edge of the second baffle plate 2112. This design not only ensures that the body 11 of the spring 1 slides down along the material guiding groove 2113 while the hanging ear portion 12 remains fixed; in the material guiding groove 2113, since the body 11 of the spring 1 slides freely and the direction is guided by the first baffle plate 2111, the spring 1 will automatically adjust to the same arrangement direction when it reaches the bottom of the first baffle plate 2111. At this time, all the springs 1 will be arranged in the same orientation, thus reducing the chaos caused by inconsistent directions in the subsequent processing steps. This uniformity of direction helps the subsequent sorting and conveying processes to proceed smoothly, improving the overall working efficiency; by ensuring that the springs 1 are arranged in a unified direction, the first direction adjustment component 211 greatly improves the conveying efficiency of the subsequent feeding guide rail. The orderly arrangement of the springs 1 in the feeding guide rail helps to avoid jams caused by inconsistent directions, ensuring that the springs 1 can be conveyed smoothly and quickly to the next processing stage. Such efficient conveying not only improves the overall efficiency of the production line but also reduces the possible downtime and the need for manual intervention.

[0038] In order to enable the spring 1 to smoothly enter the subsequent load and adjustment system and ensure that the hanging ear part 12 does not get stuck or break during the conveying process, based on this, in one embodiment, the spiral channel assembly 21 includes a second-direction adjustment assembly 212. The second-direction adjustment assembly 212 is connected to one end of the first-direction adjustment assembly 211 away from the feeding track 4. The second-direction adjustment assembly 212 includes a first transition plate 2121, a second transition plate 2122, and a third transition plate 2123. The first transition plate 2121, the second transition plate 2122, and the third transition plate 2123 are connected in sequence. The vertical plate width of the second transition plate 2122 is smaller than the horizontal plate width of the first transition plate 2121. One end of the vertical plate of the second transition plate 2122 is tangent to the horizontal plate of the first transition plate 2121, and the other end of the vertical plate of the second transition plate 2122 is tangent to the vertical plate of the third transition plate 2123. The horizontal plate height of the third transition plate 2123 is lower than the horizontal plate height of the second transition plate 2122. The first transition plate 2121 is used to transfer the spring 1 in the turntable 221 to the second transition plate 2122. The second transition is used to adjust the direction of the spring 1, so that the spring 1 transitions from a horizontal state to a vertical state. Since the horizontal plate height of the third transition plate 2123 is lower than the horizontal plate height of the second transition plate 2122, during the process of the spring 1 moving from the second transition plate 2122 to the third transition plate 2123, under the action of gravity, the orientation of the spring 1 is adjusted so that the body 11 is below and the hanging ear part 12 is above, preparing for the spring 1 to enter the first-direction adjustment assembly 211.

[0039] The vertical plate width of the second transition plate 2122 being smaller than the horizontal plate width of the first transition plate 2121 ensures that the spring 1 can smoothly and stably transition to the next stage. The second transition plate 2122 enables the direction of the spring 1 to be adjusted in a timely manner to meet the requirements of the downstream feeding track 4 for the attitude of the spring 1. This precise direction adjustment ensures the smooth conveying of the spring 1 in the subsequent processing links, which is conducive to improving the overall automated production efficiency. Since the horizontal plate height of the third transition plate 2123 is lower than the height of the second transition plate 2122, during the process of the spring 1 moving from the second transition plate 2122 to the third transition plate 2123, with the help of the action of gravity, the spring 1 will naturally slide down and change its orientation. This change makes the body 11 of the spring 1 located below and the hanging ear part 12 located above, preparing for the spring 1 to enter the first-direction adjustment assembly 211. Through this design, the installation attitude of the spring 1 adapts to the subsequent feeding requirements, enabling the spring 1 to smoothly enter the subsequent load and adjustment system and ensuring that the hanging ear part 12 does not get stuck or break during the conveying process.

[0040] In order to measure the distribution state of the spring 1 during transportation and master the quantity and position of the spring 1 at each moment, based on this, in one embodiment, the sorting and processing device further includes a vision detection device. The vision detection device includes a camera and an image processing unit. The camera is installed above the spiral channel assembly 21 and is used to capture the distribution image of the spring 1. The image processing unit is used to analyze the density and distribution of the spring 1 in the image, calculate the congestion degree of the spring 1, and the vision detection device is communicatively connected to the control terminal. The control terminal calculates the optimal vibration frequency according to the received congestion degree data of the spring 1 and through a preset algorithm. The installation position of the camera is exactly above the spiral channel assembly 21, and it can clearly capture the distribution image of the spring 1. This characteristic enables the system to monitor the distribution state of the spring 1 during transportation in real time and master the quantity and position of the spring 1 at each moment. This real-time monitoring ability provides an important basis for subsequent data analysis and can help operators or the system to detect problems in time.

[0041] The image processing unit can analyze the density and distribution of the spring 1 and calculate the congestion degree of the spring 1 by processing the image captured by the camera. This process involves technologies such as image segmentation, feature extraction, and density estimation, enabling the system to quantify the distribution state of the spring 1. The calculation of this congestion degree helps the system evaluate the effectiveness of the current transportation state, determine whether there is a blockage or uneven arrangement, and then make corresponding adjustments; the vision detection device transmits the received congestion degree data of the spring 1 to the control system in real time through the communication connection with the control terminal. This connection enables the information to flow more quickly, enabling the control system to accurately understand the current production status and react in real time. This feedback mechanism ensures the efficient operation of the entire system and reduces mistakes caused by information lag; after receiving the congestion degree data, the control terminal can use a preset algorithm to calculate the optimal vibration frequency according to the current distribution state of the spring 1. The vibration frequency has a direct impact on the transportation smoothness of the spring 1. By dynamically adjusting the vibration frequency, the transportation system can react in a timely manner according to the actual situation of the spring 1, thus effectively preventing blockages or uneven transmissions.

[0042] To ensure that the system can adapt to different production conditions and improve the flexibility of the equipment, based on this, in one embodiment, the vibration motor is communicatively connected to the control terminal, and the control terminal adjusts the vibration frequency of the vibration motor. When the degree of congestion of the springs 1 on the spiral channel assembly 21 is relatively high, the control terminal issues an instruction to reduce the vibration frequency. When the degree of congestion of the springs 1 on the spiral channel assembly 21 is relatively low, the control terminal issues an instruction to increase the vibration frequency. The design of the vibration motor allows for real-time adjustment of its vibration frequency. The control terminal receives data from the vision detection device, judges the degree of congestion of the springs 1, and issues instructions according to actual needs. This dynamic adjustment ability ensures that the system can adapt to different production conditions and improves the flexibility of the equipment; when the degree of congestion of the springs 1 on the spiral channel assembly 21 is relatively high, the control terminal timely reduces the vibration frequency, which helps to avoid the mutual collision and blockage of the springs 1 in the channel. This setting allows the springs 1 to move in the channel at a lower speed, thereby reducing the transmission problems caused by congestion, ensuring that the springs 1 flow more smoothly, and avoiding excessive retraction or accumulation; when the degree of congestion of the springs 1 is relatively low, the control terminal will issue an instruction to increase the vibration frequency. This can increase the conveying speed of the springs 1 in the channel, thus completing the task faster and improving the production efficiency. In the situation where the supply of springs 1 is sufficient, the fast vibration frequency helps to quickly sort, providing timely material support for the subsequent processing process.

[0043] In order to extend the service life of the spring 1 and improve the reliability of the product, based on this, in one embodiment, the stretching device 3 includes a clamping assembly and a stretching assembly. The clamping assembly is used to fix the spring 1, and the stretching assembly is fixed to the hanging ear portion 12 and stretches the hanging ear portion 12. The stretching assembly stretches each group of hanging ear portions 12 twice. When stretching the hanging ear portion 12 for the first time, it is mainly to perform a preliminary shape adjustment on the hanging ear portion 12 of the spring 1 to ensure that it reaches the preset standard shape. The second stretching consolidates this shape, reducing the rebound and deformation of the hanging ear portion 12 after experiencing stress. This double-stretching design can ensure the dimensional and shape accuracy of the hanging ear portion 12 in the final product, meet the requirements of subsequent processing, and improve the consistency and stability of the product; after two stretches, the material of the hanging ear portion 12 of the spring 1 will undergo plastic deformation after the application of stress. This process can effectively improve the internal microstructure of the material, increase its strength and toughness, especially the load-bearing capacity at the key use parts. This improvement helps the durability and load-bearing capacity of the hanging ear portion 12 in actual use, reducing failures or fractures caused by insufficient strength, thereby improving the overall performance of the spring 1; through two stretches, the hanging ear portion 12 of the spring 1 can effectively disperse the stress concentration caused by the processing technology, reducing the risk of crack propagation inside the material due to stress concentration. This is particularly important for mechanical components (especially those under repeated load), because stress concentration is often an important cause of fatigue failure. This design can greatly extend the service life of the spring 1 and improve the reliability of the product.

[0044] In order to reduce the abnormal conditions caused by the inaccurate position of the spring 1 and ensure the smoothness of subsequent processing or transportation, based on this, in one embodiment, a preset line is provided on the feeding track 4, and a sensor 6 and a counter 7 are provided at the position of the preset line. The sensor 6 is used to detect whether the spring 1 reaches the preset line position of the feeding track 4, and the counter 7 is used to count the number of springs 1 on the feeding track 4. The sensor 6 is set at the preset line position of the feeding track 4, and its main function is to monitor in real time whether the spring 1 reaches this position. By detecting whether the spring 1 arrives or not, the system can timely obtain its precise position during the conveying process, so as to take corresponding control measures. This real-time monitoring can effectively reduce the abnormal conditions caused by the inaccurate position of the spring 1 and ensure the smoothness of subsequent processing or transportation; when the sensor 6 detects that the spring 1 reaches the preset line position, it can send a signal to the control system to trigger subsequent operations, such as starting the next processing device or adjusting the function of the feeding track 4. This mechanism can achieve precise coordination between systems, improve operation efficiency, and reduce human intervention; by monitoring whether the spring 1 arrives at the preset position on schedule, the sensor 6 can also be used for fault detection. For example, if the spring 1 fails to arrive at the preset time, this information can be quickly fed back to the control system to give an alarm in time or take other management measures to avoid potential stagnation in the production process or uneven conveying of raw materials.

[0045] To prevent deviation or misalignment during transportation and ensure the correct positioning of the spring 1 during the processing, based on this, in one embodiment, a guiding groove 8 is provided on the feeding track 4, and the hanging ear portion 12 is clamped in the guiding groove 8 and slides along the guiding groove 8. The existence of the guiding groove 8 ensures that the hanging ear portion 12 of the spring 1 always remains within a predetermined path, preventing deviation or misalignment during transportation. This design can effectively guide the spring 1 to the inlet position of the stretching device 3 and ensure the correct positioning of the spring 1 during the processing. Accurate positioning is the basis for ensuring the processing quality, especially more important in processes that require high precision; the guiding groove 8 provides a stable movement track for the spring 1 and can reduce the influence of external disturbances (such as vibrations, wind forces, etc.) on the position of the spring 1. This stable guiding can reduce the bumps and shakes of the spring 1 during transportation, enabling it to slide in a consistent manner, thereby improving the robustness and reliability of the entire transportation process; the design of the guiding groove 8 ensures the consistency of the direction of the spring 1 during transportation. The key to achieving this goal lies in ensuring that each hanging ear portion 12 always remains within the guiding groove 8, so that the spring 1 can reach the stretching device 3 at a consistent angle and direction. This is crucial for the subsequent process steps (such as stretching, compression, etc.) that require high consistency and accuracy. The same input conditions will help maintain the consistency of the processing results and improve the overall quality of the product.
