Description

Technical Field

[0001] This application relates to the field of coil spring manufacturing technology, and in particular to a coil spring fixing device. Background Technology

[0002] In existing technologies, coil springs have a wide range of applications. With the continuous development of industrial production, the requirements for the efficiency and quality of coil spring packaging are also increasing. Efficient and accurate coil spring packaging not only protects the springs from damage during transportation and storage but also improves the automation level of the production process. Since coil springs store and release mechanical energy through elastic deformation, they need to be shaped using cable ties before leaving the factory to prevent them from deforming and tangling due to accidental ejection during transportation and storage. However, current technologies rely on manual operation. Workers need to manually place the coil springs in the appropriate position and then secure them with cable ties. This method is not only inefficient but also makes it difficult to guarantee consistent packaging quality for each coil spring due to the instability of manual operation. Some technologies use simple mechanical devices to assist packaging, but these devices are often single-function, only completing part of the packaging process, and still require significant manual intervention. For example, some devices can only position the coil spring, while the connection and tightening of the cable ties still need to be done manually; some devices can connect the cable ties, but cannot guarantee the stability of the coil spring during the packaging process, which can easily lead to the cable ties not being securely tightened.

[0003] However, these coil spring packaging methods have obvious technical defects. Manual packaging is labor-intensive, inefficient, and difficult to meet the needs of large-scale production. At the same time, the quality of coil spring packaging is unstable. The cable ties are not tightly attached to the coil spring, and the coil spring is prone to falling off the cable ties, which will affect the subsequent use and transportation of the coil spring.

Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0034] This application discloses a coil spring fixing device.

[0035] Reference Figure 1 and Figure 2As shown, a coil spring fixing device includes a first feeding assembly 1 for positioning a coil spring 6, a first clamping and transferring assembly 2 arranged on the side of the first feeding assembly 1 for clamping and transferring the coil spring 6 after it has been guided by the first feeding assembly 1, a rotating assembly 3 arranged on the side of the first feeding assembly 1 for driving the coil spring 6 to rotate, a second feeding assembly 4 arranged on the opposite side of the rotating assembly 3 for attaching a cable tie 7 to the coil spring 6 on the rotating assembly 3, and a discharging assembly 5 arranged on the side of the rotating assembly 3 for fastening and discharging the coil spring 6. Through the cooperation of these components, an automated packaging process is achieved for the coil spring 6 from positioning, transferring, attaching the cable tie 7, fastening the cable tie 7 to discharging, greatly improving packaging efficiency and quality.

[0036] Reference Figure 2 As shown, the first feeding assembly 1 includes a first feeding frame 11, a first conveyor belt 12 arranged on the first feeding frame 11, a placement seat 13 arranged at intervals on the first conveyor belt 12 for placing the coil spring 6, and a first guide member 14 arranged on the first feeding frame 11 for guiding the bent portion 61 of the coil spring 6.

[0037] Reference Figure 2 As shown, the placement seat 13 has a first cavity 131 for placing the coil spring 6. Baffles are arranged on both sides of the placement seat 13, and a lifting rod is provided inside the placement seat 13 to lift the coil spring 6 out of the placement seat 13. The interior of the first cavity 131 has an arc-shaped structure, and this arc-shaped structure is adapted to the coiled coil spring 6. The baffles on both sides of the placement seat 13 limit the coil spring 6, preventing it from tipping over during transport. The baffles abut against both sides of the coil spring 6 in its annular state. Specifically, the lifting rod is located at the center of the placement seat 13. The lifting rod can be driven by a motor (as in the prior art) to lift the coil spring 6 located inside the placement seat 13. The height of the lifting rod is higher than the height of the baffles.

[0038] Reference Figure 2 and Figure 3As shown, the first guide component 14 has a guide housing 141 arranged on the first feeding frame 11, a first gripper 142 arranged at the input end of the guide housing 141 for abutting the bent portion 61 of the coil spring 6, and a second gripper 143 abutting the coil spring 6. The first gripper 142 has first rollers 1421 arranged on it that abut against the upper and lower sides of the bent portion 61, and the second gripper 143 has second rollers 1431 arranged on it that abut against the sides of the steel strip of the coil spring 6. The guide housing 141 has a through groove 1411 adapted to the bent portion 61 and the steel strip of the coil spring 6. The coil spring 6, after being gripped by the first gripper 142 and the second gripper 143, is inserted into the through groove 1411 for limiting its position. The guide housing 141 serves a supporting and protective function, and the first gripper 142 and the second gripper 143 can be pneumatic grippers used in the prior art to achieve the opening and closing of the two grippers. The first roller 1421 and the second roller 1431 can be made of rubber to increase friction, thereby better contacting the bending part 61 and the steel strip of the coil spring 6, and reducing damage to the surface of the coil spring 6.

[0039] The clamping action of the first gripper 142 and the second gripper 143 can centrally position the originally free bent portion 61 and the extended steel strip of the coil spring 6. A clearance is provided between the first gripper 142 and the second gripper 143 to allow the coil spring 6 to pass through. Furthermore, an infrared detector is arranged on the first feeding frame 11 to detect the state of the coil spring 6 as it is fed into the position between the first gripper 142 and the second gripper 143. The first gripper 142 first clamps and positions the bent portion 61 vertically, and then the second gripper 143 clamps the coil spring 6 vertically. Simultaneously, the upper and lower clamping plates of the first gripper 142 have the same curvature as the bent portion 61, and the upper and lower clamping plates of the second gripper 143 have the same shape as the extended steel strip. The first roller 1421 and the second roller 1431 on the first gripper 142 and the second gripper 143 abut against the coil spring 6. After being clamped, the first gripper 142 and the second gripper 143 are aligned with the through groove 1411 on the guide housing 141 in the same plane. At the same time, the coil spring 6 on the placement seat 13 is conveyed by the first conveyor belt 12. The bent part 61 and the steel strip can be guided by the first roller 1421 and the second roller 1431 and enter the through groove 1411 in the guide housing 141. The coil spring 6 is shaped by the limiting cooperation between the inside of the guide housing 141 and the bent part 61.

[0040] Reference Figure 4 and Figure 5As shown, the first clamping and transferring assembly 2 includes a transfer frame 21, a transfer platform 22 arranged on the transfer frame 21, a first guide rail 23 arranged on the transfer frame 21 for the transfer platform 22 to slide toward the first feeding assembly 1, a second guide rail 24 arranged on the transfer platform 22 and parallel to the ground, a sliding plate 25 arranged on the second guide rail 24, a first transfer gripper 26 arranged on the sliding plate 25 for clamping the bent portion 61 guided out of the through groove 1411, and a second transfer gripper 27 arranged on the sliding plate 25 for clamping the coil spring 6 steel strip guided out of the through groove 1411.

[0041] The transfer frame 21 provides support for the entire transfer assembly. A first guide rail 23 is mounted on the transfer frame 21, allowing the transfer platform 22 to slide along it, thus enabling the transfer platform 22 to move towards the output end of the first conveyor belt 12. A first drive motor is mounted on the transfer frame 21 and connected to the end face of the transfer platform 22 away from the first conveyor belt 12, providing power for the sliding of the transfer platform 22. Simultaneously, a second guide rail 24 is arranged towards the output end of the first conveyor belt 12, and a second drive motor is also arranged on the side of the sliding plate 25 to enable its movement. The first transfer gripper 26 and the second transfer gripper 27 are at the same height as the through groove 1411 on the guide housing 141. The first transfer gripper 26 and the second transfer gripper 27 move to the outlet position of the through groove 1411, and the engagement distance between the first transfer gripper 26 and the second transfer gripper 27 is greater than the gap in the through groove 1411. When the bent portion 61 and the extended steel strip portion move out of the through slot 1411, the first and second transfer clamping claws clamp and retract the bent portion 61 and the steel strip portion. At the same time, the lifting rod inside the placement seat 13 rises to lift the coil spring 6, preventing the baffles on both sides of the placement seat 13 from affecting the coil spring 6. By clamping the bent portion 61 and the extended steel strip, the clamping stability of the entire coil spring 6 can be maintained, and the toughness of the steel strip itself can ensure that the swaying frequency of the coiled coil spring 6 is stable. After clamping, the coil spring 6 is transferred to the rotating assembly 3 by the movement of the sliding plate 25.

[0043] The rod output component 43 has a first rod 431 arranged on the second feeding frame 41 for attaching and placing cable ties 7. The cable ties 7 are evenly arranged on the first rod 431, and there are at least two first rods 431. In this application, three first rods 431 are installed, and the cable ties 7 are completely attached to the outside of the first rod 431. A ring-shaped first push block 432 is arranged on the side of the first rod 431. The first push block 432 is hollow and slides on the first rod 431. The inner diameter of the first push block 432 is the same as the diameter of the first rod 431. A first push rod 433 is arranged on the end face of the first push block 432 away from the output end of the first rod 431, and a telescopic motor 434 is arranged on the side of the first push rod 433 away from the first push block 432. The first push block 432 pushes the cable ties 7 attached to the first rod 431 toward the output end of the first rod 431. The first threading rod 431 can be made of stainless steel to ensure its strength and surface smoothness, facilitating the sliding of the cable tie 7.

[0044] Reference Figure 6 As shown, an idle speed component 435 is provided at the output end of the first threading rod 431. The idle speed component 435 includes a first drive wheel 4351 arranged on the second feeding frame 41. The first drive wheel 4351 is perpendicular to the first threading rod 431 and arranged on the upper side of the first threading rod 431. The drive wheel abuts against the cable ties 7 on the first threading rod 431, and a first guide rod 4311 facing the opening component 44 is provided on the first threading rod 431. The first drive wheel 4351 is a rubber roller, which reduces damage to the surface of the cable ties 7 when in contact with them. The motor drives the drive wheel to rotate slowly, driving a single cable tie 7 to be output from the first threading rod 431 to the first guide rod 4311. The idle speed component 435 can realize the individual output of the cable ties 7 on the first threading rod 431 at a set speed. At the same time, an adjusting bolt is provided on the drive wheel of the idle speed component 435, which can realize the adjustment of the distance between the drive wheel and the first threading rod 431.

The discharge component 5 includes a discharge bracket and a second conveyor belt 51 arranged on the discharge bracket. The push plate component 37 pushes the tied coil spring 6 to push the coil spring 6 off the fixed plate 32 and onto the second conveyor belt 51, and then transports it to the next process through the second conveyor belt 51.

[0053] The implementation principle of the coil spring fixing device in this application embodiment is as follows: The cable tie 7 packaging machine realizes the automated packaging process of coil spring 6 from positioning, transfer, cable tie 7 connection, binding to discharge through the coordinated work of various components. The first feeding component 1 positions and guides the coil spring 6. The worker places the coil spring 6 in the placement seat 13, with the bent part 61 facing the guide housing 141. As the placement seat 13 moves with the first conveyor belt 12, when the bent part 61 and the steel strip part pass between the first gripper 142 and the second gripper 143, the first gripper 142 and the second gripper 143 clamp and position the bent part 61 and the steel strip part, ensuring that the bent part 61 and the steel strip are coaxially positioned with the through groove 1411 on the guide housing 141. Furthermore, the first roller 1421 and the second roller 1431 on the first gripper 142 and the second gripper 143 can guide the sliding coil spring 6 to accurately engage into the through groove 1411 for limiting.

[0054] The two jaws on the first clamping and transferring assembly 2 are aligned with the through slot 1411 of the guide housing 141. The first clamping and transferring assembly 2 clamps the coil spring 6 and transfers it to the rotating assembly 3. The second feeding assembly 4 outputs and expands the cable tie 7. The worker can adjust the drive wheel on the idle speed component 435 in advance to increase the distance between the drive wheel and the first threading rod 431. The worker can then pre-load the annular cable tie 7 onto the first threading rod 431 to achieve the feeding of the cable tie 7. Finally, the positions of the drive wheel and the first threading rod 431 are adjusted. The first push block 432 pushes the cable tie 7 on the first threading rod 431 toward the four-jaw chuck 442. Guided by the idle speed component 435, it slides onto the second guide rod 4421. The four-jaw chuck 442 then expands the cable tie 7. The rotating assembly 3 enables the rotation of the coil spring 6 and the binding of the cable tie 7. The first clamping and transferring assembly 2 transfers the coil spring 6 to the rotating head 33 and aligns the bent part 61 with the groove on the rotating head 33 for insertion. Then, the first clamping and transferring assembly 2 retracts, and the flip plate rotates under the drive of the rotating motor 34, completely inserting the exposed portion of the coil spring 6 into the groove of the rotating head 33. At the same time, while the coil spring 6 is being transferred, the sliding column 352 on the fixing plate 32 slides to a suitable position in the sliding groove 351, and after the coil spring 6 is inserted, it can abut against the extended steel strip on the side of the coil spring 6 as a fulcrum. After the rotating column head 33 rotates, it reverses and opens the originally formed coil spring 6. The bent part 61 inside the coil spring 6 engages and limits the sliding column 352. After the flap opens, the supporting platform 441 moves towards the fixed plate 32, and the positioning column 36 extends out from the round hole. The opened cable tie 7 is completely wrapped around the outside of the reversed coil spring 6, and the positioning column 36 is also arranged inside the cable tie 7. At this time, the four-jaw chuck 442 retracts, and the originally opened cable tie 7 begins to become irregular. The highest point of the cable tie 7 abuts against the positioning column 36, and the cable tie 7 is hung on the positioning column 36. At the same time, the entire cable tie 7 still wraps around the coil spring 6. After the flap rotates and closes, the positioning column 36 retracts, and the cable tie 7 falls onto the coil spring 6 due to gravity. The rotating column head 33 rotates clockwise to relax the coil spring 6, and at the same time abuts and limits the outer cable tie 7. Under the action of elastic force, the coil spring 6 fits tightly with the cable tie 7, realizing the binding of the cable tie 7. The discharge assembly 5 delivers the bound coil spring 6. Compared with existing technologies, this packaging machine improves packaging efficiency and quality, reduces labor costs, and solves the problems of manual packaging and simple mechanical assisted packaging, demonstrating strong practicality and innovation.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
