Abstract
Description
Technical Field
[0001] This application relates to the field of bagged spring technology, and in particular to a spring compression conveying assembly, a bagged spring machine, and a spring conveying method. Background Technology
[0002] A spring coiling machine forms springs from steel wire, compresses them, and then seals them in a cloth bag by welding or sewing, thus obtaining a bagged spring string. In related technologies, bagged spring machines use a gradually narrowing conveyor channel to compress the springs while conveying them. However, due to the elastic deformation of the springs themselves, the simultaneous compression and conveying in the channel can cause the springs to arch radially, or even pop out and detach from the conveyor channel. Arching of the springs can deform the sealed bagged spring string, while detachment can result in empty bags within the bagged spring string. Summary of the Invention
[0003] To solve at least one of the above-mentioned technical problems, this application provides a spring compression conveying assembly, a bag spring machine, and a spring conveying method, and the technical solution adopted is as follows.
[0004] The bag spring machine provided in this application includes a spring compression conveying assembly.
[0005] The spring compression conveying assembly provided in this application includes a spring compression assembly and a spring conveying assembly. The spring compression assembly includes a base, a limiting member, and compression members. The limiting member is disposed on the base and has a limiting groove extending along a first direction. The limiting member is used to prevent radial deformation during the spring compression process. Two compression members are movably disposed on the base, with each compression member located at one end of the limiting groove. The two compression members can move along the first direction to move closer to or further away from each other. The spring is placed in the limiting groove and between the two compression members. The compression members move closer to each other to compress and clamp the spring. The spring conveying assembly and the base move closer to each other along a second direction so that the feed end of the spring conveying assembly enters the spring compression assembly. The two compression members move further away from each other to transfer the compressed spring to the spring conveying assembly.
[0006] In some embodiments of this application, the compression member is provided with a clearance groove, the clearance groove is formed along a second direction, and the clearance groove forms a notch on the side of the compression member for abutting the end of the spring. The feed end of the spring conveying assembly extends into the clearance groove, and when the compression members move away from each other, the spring conveying assembly separates from the compression member from the notch formed by the clearance groove, so that the spring is transferred to the spring conveying assembly.
[0007] In some embodiments of this application, the spring conveying assembly includes two opposing first conveying assemblies, which together clamp and convey the compressed spring. Each first conveying assembly includes at least one layer of conveying member, and the compression member is provided with at least one layer of the clearance groove. The feed end of the conveying member can extend into the clearance groove.
[0008] In some embodiments of this application, the limiting member is provided with a second clearance notch to avoid the spring conveying assembly when the spring conveying assembly enters the spring compression assembly at the feed end of the spring conveying assembly.
[0009] In some embodiments of this application, the limiting member is provided as at least one, the limiting member including two oppositely arranged side baffles, the spacing of the side baffles being adjustable to change the width of the limiting groove to accommodate springs with different waist diameters.

[0013] In some embodiments of this application, the spring compression assembly includes a first drive assembly disposed on the base, the first drive assembly driving the compression members to move closer or further apart from each other.
[0014] In some embodiments of this application, the first driving component includes a first driver and a first rotating structure. The first rotating structure is connected to the compression member via a connecting rod at a position offset from its own rotation center. The first driver is connected to the first rotating structure and drives the first rotating structure to rotate, so as to cause the compression members to move closer or further apart.
[0015] In some embodiments of this application, the spring compression assembly includes a second drive assembly connected to the base, the second drive assembly driving the base to reciprocate along a second direction.
[0016] In some embodiments of this application, the second driving component includes a second driver and a second rotating structure. The second rotating structure is connected to the base via a connecting rod at a position offset from its own rotation center. The second driver connects to the second rotating structure and drives the second rotating structure to rotate. The second rotating structure drives the base to move along a second direction so that the base is close to the feed end of the spring conveying component.
[0017] In some embodiments of this application, the spring compression conveying assembly includes a spring transfer assembly for transferring a spring manufactured by a spring coiling machine to the limiting member.
[0018] In some embodiments of this application, the spring transfer assembly includes a second conveying assembly and a magnetic base. The magnetic base is disposed on the second conveying assembly and magnetically grasps the spring. The magnetic base moves to the opening side of the limiting member, so that the spring enters the limiting groove and is located between the two compression members. The spring is compressed within the space enclosed by the magnetic base, the limiting member, and the compression members.
[0019] In some embodiments of this application, the limiting member is movably disposed on the base, the limiting member moves upward to allow the spring to enter the limiting groove, and the limiting member moves downward to avoid the feed end of the spring conveying assembly.
[0020] The spring conveying method provided in this application is implemented based on a spring compression conveying assembly, and the spring conveying method includes the following workflow:
[0021] The spring enters the limiting groove and is located between the two compression members, which move closer to each other to compress the spring in the limiting groove;
[0022] The base moves toward the spring conveyor assembly, and the feed end of the spring conveyor assembly inserts into the compressor.
[0023] The compression components are separated from each other, and the two ends of the spring abut against the spring delivery assembly so that the spring is transferred from the compression components to the spring delivery assembly;

[0025] In some embodiments of this application, the limiting member rises to allow the spring to enter the limiting groove and be positioned between the two compression members; the limiting member descends to allow the feed end of the spring conveying assembly to insert into the compression member.

The sidewall of the limiting member limits the side of the spring, preventing the spring from arching radially. After the feed end of the spring conveying assembly enters the spring compression assembly, the compression members move away from each other, and the compressed spring is transferred to the spring conveying assembly. This application can be widely applied in the field of bagged spring string technology. Attached Figure Description

[0041] The following is in conjunction with the appendix Figure 1 To be continued Figure 4-4 The embodiments of this application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0043] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0044] This application relates to a bagged spring machine, which includes a spring compression conveying assembly capable of compressing and conveying the springs in a compressed state. Further, the bagged spring machine includes a sealing mechanism located downstream of the spring compression conveying assembly. The spring compression conveying assembly conveys the springs to the sealing mechanism, which seals the springs in a cloth bag to obtain a bagged spring string.
[0045] Furthermore, the bag spring machine includes a spring coiling machine 4000, which forms springs from steel wire.
[0046] The other components and operation of the bag spring machine are already described in the relevant art to those skilled in the art, and will not be described in detail here. The structure of the spring compression and conveying assembly will be introduced below.
[0047] This application relates to a spring compression conveying assembly, combined with the attached... Figure 1 and appendix Figure 3-1 and attached Figure 3-2 The spring compression conveying assembly includes a spring compression assembly 1000 and a spring conveying assembly 2000. The spring compression assembly 1000 is used to simultaneously compress and clamp at least one spring. The compressed spring is transferred from the spring compression assembly 1000 to the spring conveying assembly 2000. The spring conveying assembly 2000 conveys the spring in a compressed state to the next station for making bagged spring strings.
[0048] The spring conveying assembly 2000 has its feed end capable of entering the spring compression assembly 1000, and the spring compressed and held in the spring compression assembly 1000 is transferred to the spring conveying assembly 2000. Afterward, the spring conveying assembly 2000 separates from the spring compression assembly 1000, the spring conveying assembly 2000 conveys the spring to the next station, and the spring compression assembly 1000 compresses a new spring.
[0049] This application relates to a spring compression assembly 1000, in conjunction with the attached... Figure 2-1 The spring compression assembly 1000 includes a base 1100, a limiting member 1200, and a compression member 1300. The limiting member 1200 is disposed on the base 1100, and the spring to be compressed is placed in the limiting member 1200. The compression member 1300 is disposed on the base 1100. (See attached diagram.) Figure 2-1 Both the limiting member 1200 and the compression member 1300 are disposed on the upper side of the base 1100. There are two compression members 1300, one at each end of the base 1100 near the limiting member 1200. Furthermore, the two compression members 1300 are movably disposed on the base 1100, and the compression members 1300 at both ends of the limiting member 1200 can move closer or further apart to compress or release the spring.
[0050] It should be noted that the spring conveying assembly 2000 and the base 1100 are brought close to each other so that the feed end of the spring conveying assembly 2000 enters the spring compression assembly 1000. After the feed end of the spring conveying assembly 2000 enters the spring compression assembly 1000, the compression components 1300 move away from each other and release the spring, and the compressed spring is transferred to the spring conveying assembly 2000.
[0051] The limiting member 1200 has a limiting groove extending along a first direction parallel to the length of the limiting member 1200. Two compression members 1300 are located at opposite ends of the limiting groove. It is understood that, along the first direction, the spring is placed in the limiting groove and between the two compression members 1300. Further, a portion of the compression member 1300 is located within the limiting groove. The compression member 1300 moves in the first direction, causing the compression members 1300 at both ends of the limiting member 1200 to move closer together to compress and clamp the spring. The sidewall of the limiting member 1200 has a limiting effect on the side of the spring, preventing the spring from arching radially and preventing radial deformation during compression. It also has a shaping and anti-deformation function for the compressed spring.
[0052] In one embodiment, the spring compression assembly 1000 includes a first drive assembly disposed on the base 1100 and connected to the compression members 1300. The first drive assembly drives the compression members 1300 to move closer to or further away from each other. Further, the first drive assembly simultaneously drives the compression members 1300 at both ends of the limiting member 1200 to move, so that the movement of the compression members 1300 is synchronized.
[0053] Specifically, the first drive assembly includes a first driver and a first rotating structure 1402. The first driver includes a motor and is connected to the first rotating structure 1402. The first rotating structure 1402 has a rotation center, and the shaft at the output end of the first driver is connected to the rotation center of the first rotating structure 1402. Further, the first rotating structure 1402 is connected to the compression member 1300 at a position offset from its own rotation center via a connecting rod, and both ends of the connecting rod are hinged. In this case, the first driver drives the first rotating structure 1402 to rotate, and the first rotating structure 1402 pulls or pushes the compression member 1300 through the connecting rod, thereby causing the compression members 1300 to move closer or further apart.
[0054] Combined with appendix Figure 2-3 The first rotating structure 1402 is configured as a circular turntable, and the shaft at the output end of the first driver is connected to the center of the turntable. The turntable is connected to the compression member 1300 at a position off-center via a connecting rod. Furthermore, the hinge positions of the connecting rods on the turntable corresponding to the two compression members 1300 are on the same circumference.
[0055] Regarding the first rotating structure 1402, it can also be designed as follows: In some examples, the first rotating structure 1402 is a crossbar with its center as the rotation center, and both ends of the crossbar are connected to the compression member 1300 via connecting rods. In other examples, the first rotating structure 1402 is a disc cam with its rotation center connected to the shaft of the first driver output end. The disc cam has two eccentric positions, which are symmetrically distributed about the rotation center of the disc cam, and connecting rods for connecting the compression member 1300 are hinged at both eccentric positions.
[0056] In some embodiments, the spring compression assembly 1000 further includes a first guide structure 1401, at least one of which is provided. The first guide structure 1401 is arranged along a first direction to guide the movement of the compression member 1300. (See attached diagram.) Figure 2-3 Two first guide structures 1401 are provided, each located on the upper side of the base 1100. Each first guide structure 1401 includes a guide rail, and the bottom of the compression member 1300 is slidably connected to the guide rail via a slider. It can be understood that the first rotating structure 1402 is connected to the slider via a connecting rod.
[0057] Of course, as an alternative, it can also be designed as follows: the first guide structure 1401 includes a guide rod or a guide groove.
[0058] Regarding the first drive assembly, at least the following alternative examples exist: The first drive assembly drives the compressor 1300 to move closer or further apart using a ball screw assembly. Alternatively, the first drive assembly drives the compressor 1300 to move closer or further apart using a rack and pinion assembly. Alternatively, the first drive assembly drives the compressor 1300 to move closer or further apart using a belt drive. Alternatively, the first drive assembly drives the compressor 1300 to move closer or further apart using a cylinder or hydraulic cylinder.
[0059] In one embodiment, the spring compression assembly 1000 includes a second drive assembly connected to a base 1100. The second drive assembly drives the base 1100 to reciprocate along a second direction perpendicular to the first direction, so that the base 1100 moves closer to or further away from the spring conveying assembly 2000, thereby allowing the feed end of the spring conveying assembly 2000 to be inserted into the spring compression assembly 1000 or the spring conveying assembly 2000 to be separated from the spring compression assembly 1000.
[0060] Specifically, the second drive assembly includes a second driver 1501 and a second rotating structure 1502. The second driver 1501 includes a motor and is connected to the second rotating structure 1502. The second rotating structure 1502 has a rotation center, and the shaft at the output end of the second driver 1501 is connected to the rotation center of the second rotating structure 1502. Further, the second rotating structure 1502 is connected to the base 1100 at a position offset from its own rotation center via a connecting rod, and both ends of the connecting rod are hinged. In this case, the second driver 1501 drives the second rotating structure 1502 to rotate, and the second rotating structure 1502 pulls or pushes the base 1100 via the connecting rod, thereby moving the base 1100. The base 1100 moves along a second direction, thereby bringing the base 1100 closer to the feed end of the spring conveying assembly 2000, so that the spring conveying assembly 2000 and the base 1100 move closer to each other along the second direction.
[0061] Combined with appendix Figure 2-1 and attached Figure 2-3 The second rotating structure 1502 is set as a circular turntable, and the shaft at the output end of the second driver 1501 is connected to the center of the turntable. The turntable is connected to the base 1100 at a position off-center via a connecting rod.
[0062] It is understandable that, as an alternative, the second rotating structure 1502 can at least be designed as a cam. Alternatively, the second rotating structure 1502 can be a crossbar, with one end fixedly connected to the shaft at the output end of the second driver 1501, and the other end hinged to the connecting rod connected to the base 1100.
[0063] In some embodiments, the spring compression assembly 1000 further includes a second guide structure 1503, at least one of which is provided and arranged along a second direction to guide the movement of the base 1100. (See attached diagram) Figure 2-1 and attached Figure 2-3 Two second guide structures 1503 are provided. The second guide structure 1503 is located on the lower side of the base 1100. The second guide structure 1503 includes a guide rail. The bottom of the base 1100 is slidably connected to the guide rail by a slider.
[0064] Of course, as an alternative, it can also be designed as follows: the second guide structure 1503 includes a guide rod or a guide groove.
[0065] Regarding the second drive assembly, at least the following alternative examples exist: the second drive assembly drives the base 1100 to move via a ball screw assembly. Alternatively, the second drive assembly drives the base 1100 to move via a rack and pinion assembly. Alternatively, the second drive assembly drives the base 1100 to move via a belt drive. Alternatively, the second drive assembly drives the base 1100 to move via a cylinder or hydraulic cylinder.
[0066] In one implementation, the limiting member 1200 descends to avoid the feed end of the spring conveying assembly 2000. Specifically, the limiting member 1200 can move up and down along a third direction. On one hand, the limiting member 1200 moves upward to allow the spring to enter the limiting groove; on the other hand, when the feed end of the spring conveying assembly 2000 is inserted into the spring compression assembly 1000, the limiting member 1200 moves downward, thereby allowing the limiting member 1200 to avoid the spring conveying assembly 2000.
[0067] Combined with appendix Figure 2-1 and attached Figure 2-2 The spring compression assembly 1000 includes a third drive assembly 1600, which is disposed on the base 1100 and connected to a limiting member 1200. The third drive assembly 1600 can drive the limiting member 1200 to move up and down. When the compression members 1300 approach each other and compress the spring, the third drive assembly 1600 drives the limiting member 1200 to move downward, separating the limiting member 1200 from the spring. On the other hand, when the third drive assembly 1600 drives the limiting member 1200 to move upward, it moves the limiting member 1200 to a position where it can receive the spring.
[0068] Specifically, two third drive components 1600 are configured, and the two ends of the limiting member 1200 are respectively connected to the two third drive components 1600. Furthermore, the third drive components 1600 pneumatically drive the limiting member 1200 to move up and down.
[0069] Regarding the third drive assembly 1600, at least the following alternative examples exist: the third drive assembly 1600 drives the limit member 1200 to move via a ball screw pair. Alternatively, the third drive assembly 1600 drives the limit member 1200 to move via a gear and rack mechanism. Alternatively, the third drive assembly 1600 drives the limit member 1200 to move via a belt drive. Alternatively, the third drive assembly 1600 drives the limit member 1200 to move via a hydraulic cylinder.
[0070] As one implementation method, to increase the number of springs in the spring compression assembly 1000, combined with the attached... Figure 2-1 and attached Figure 3-1The limiting member 1200 is provided in at least two parts, and the limiting members 1200 are spaced apart along the second direction. Further, the compression member 1300 extends along the second direction and crosses each limiting member 1200 along the second direction. When the compression members 1300 approach each other, the compression members 1300 can compress the springs in each limiting member 1200 at the same time to improve efficiency.
[0071] Combined with appendix Figure 2-2 The compression member 1300 is provided with a first clearance notch 1301. During the reciprocating movement of the compression member 1300 along the first direction, the first clearance notch 1301 is used to avoid the side wall of the limiting member 1200. When the limiting member 1200 is provided with at least two intervals along the second direction, the compression member 1300 is correspondingly provided with at least two first clearance notches 1301 at intervals along the second direction, and the structure formed between two adjacent first clearance notches 1301 on the compression member 1300 forms an insertion end, which extends into the limiting groove to abut against the spring.
[0072] As an alternative implementation, the limiting member 1200 is provided as one, and the compression member 1300 is provided in the limiting groove.
[0073] In one implementation, the width of the limiting groove is adjustable to accommodate springs with different waist diameters. Specifically, the limiting member 1200 includes two side baffles 1201, which extend along a first direction and are arranged opposite to each other. The area between the two side baffles 1201 forms a limiting groove, and the side baffles 1201 form the sidewalls of the limiting member 1200. The distance between the two side baffles 1201 is adjustable to change the width of the limiting groove to accommodate springs with different waist diameters.
[0074] Furthermore, a support portion 1202 is provided at the bottom of the side baffle 1201. The support portion 1202 extends from the side of the side baffle 1201 into the limiting groove to form a bottom plate at the bottom of the limiting groove. The support portion 1202 is used to support the spring in the limiting groove. (See attached diagram) Figure 2-2 The cross-section of the side baffle 1201 is formed in an L shape so that the side baffle 1201 is formed as an L-shaped plate.
[0075] Regarding the shape of the side baffle 1201, at least one alternative design is possible: the side of the side baffle 1201 near the limiting groove is set as an inclined surface to abut against the side of the spring. In this case, the inclined surface is located on the opposite side of the side baffle 1201 in the limiting member 1200, so that the cross-section of the limiting groove is formed into a V shape.
[0076] It is understandable that when the compression member 1300 is provided with a first clearance notch 1301, the first clearance notch 1301 is used to avoid the side baffle 1201 of the limiting member 1200. (See attached diagram) Figure 2-1 and attached Figure 2-2 The two adjacent side baffles 1201 of the two adjacent limiting members 1200 are located at a corresponding first clearance notch 1301. When the compression member 1300 moves along the first direction, the first clearance notch 1301 avoids the side baffles 1201 of the limiting member 1200.
[0077] Furthermore, when the compression member 1300 rises, the side baffle 1201 partially enters the first clearance notch 1301 so that the extended end of the compression member 1300 enters the limiting groove, and the first clearance notch 1301 can avoid the side wall of the rising limiting member 1200.
[0078] In some examples, the compression member 1300 is provided with a sliding part that passes through the limiting groove. The sliding part is movably disposed on the base 1100, located at the end of the extended end and passing through the limiting groove. The sliding part is connected to the slider where the compression member 1300 is located, and the sliding part moves in the limiting groove along a first direction. In this case, the limiting groove acts as a sliding groove for the sliding part.
[0079] In one embodiment, the limiting member 1200 is provided with a second clearance notch 1203 to avoid the spring conveying assembly 2000 when the feed end of the spring conveying assembly 2000 enters the spring compression assembly 1000. In this case, the limiting member 1200 can be configured to be movable up and down, or it can be configured not to be movable up and down.
[0080] Combined with appendix Figure 3-4 The second clearance notch 1203 is provided on the side baffle 1201, and the second clearance notch 1203 is formed on the side baffle 1201 at the middle of the limiting groove. When the two compression members 1300 approach each other and compress the spring, the compressed spring is in the middle of the limiting groove.
[0081] In one embodiment, the compression member 1300 is provided with a relief groove 1302, which is formed along a second direction. The relief groove 1302 forms an inlet at one end of the compression member 1300 facing the spring conveying assembly 2000, so that the feed end of the spring conveying assembly 2000 can enter the compression member 1300 from the inlet of the relief groove 1302.
[0082] Furthermore, the clearance groove 1302 has a notch formed on the side of the compression member 1300 for abutting the end of the spring, and the clearance groove 1302 is formed in a U-shape. When the feed end of the spring conveying assembly 2000 extends into the clearance groove 1302 and the compression members 1300 move away from each other in the first direction, the spring conveying assembly separates from the compression member 1300 from the notch formed by the clearance groove 1302, and the compression member 1300 releases the spring so that the spring is transferred to the spring conveying assembly 2000.
[0083] Combined with appendix Figure 3-1 Appendix Figure 3-2 The spring conveying assembly 2000 includes two opposing first conveying assemblies 2100, with the area formed between the two first conveying assemblies 2100 used for conveying the spring. Further, the area between the two first conveying assemblies 2100 used for conveying the spring is of equal width. During the conveying process, the first conveying assemblies 2100 abut against the ends of the spring, the two first conveying assemblies 2100 jointly clamp the compressed spring, and the first conveying assemblies 2100 compress the spring to keep it in a compressed state during conveying.
[0084] It is understandable that one end of the first conveying assembly 2100 located at the feed end of the spring conveying assembly 2000 can enter the clearance groove 1302 of the compression member 1300. After the compression members 1300 move away from each other, the first conveying assembly 2100 abuts against the end of the spring, so that the spring conveying assembly 2000 receives the spring from the compression member 1300.
[0085] In some examples, the first conveying assembly 2100 includes a conveyor 2101, the inlet end of which can extend into the clearance groove 1302, and the conveyor 2101 can clamp the spring and convey the spring in a second direction. Specifically, the conveyor 2101 is configured as a toothed chain.
[0086] Furthermore, the first conveying assembly 2100 includes at least one layer of conveying members 2101, and the compression member 1300 is provided with at least one layer of clearance grooves 1302. It is understood that when the conveying members 2101 are configured with at least two layers, multiple conveying members 2101 simultaneously clamping the spring can improve the stability of the spring during conveying. In the first conveying assembly 2100, each layer of conveying members 2101 is equipped with upper and lower support plates.
[0087] In one embodiment, the spring compression conveying assembly includes a spring transfer assembly 3000, which is used to transfer the spring produced by the spring coiling machine 4000 to the limiting member 1200.
[0088] Specifically, the spring transfer assembly 3000 includes a second conveying assembly and a magnetic base 3100. The second conveying assembly includes a chain, and the magnetic base 3100 is disposed on the second conveying assembly, gripping the spring magnetically. Further, when the magnetic base 3100 moves to the opening side of the limiting member 1200, the magnetic base 3100 flips over, and the spring is located on the downward-facing side of the magnetic base 3100. The position of the spring corresponds to the position of the limiting member 1200. At this time, the spring enters the limiting groove and is located between the two compression members 1300. The compression members 1300 approach each other and clamp the spring, compressing it within the space enclosed by the magnetic base 3100, the limiting member 1200, and the compression members 1300. It can be understood that as the magnetic base 3100 gradually moves away from the limiting member 1200, the spring separates from the magnetic base 3100, thereby transferring the spring from the magnetic base 3100 to the limiting member 1200.
[0089] In some examples, a portion of the conveying section on the second conveying assembly near the spring compression assembly 1000 is parallel to the second direction. When the magnetic chuck 3100 moves to this portion of the conveying section, the magnetic chuck 3100 flips downward and the distance between the magnetic chuck 3100 and the limiting member 1200 remains unchanged, so that the spring is held in the limiting groove so that the compression member 1300 can clamp and compress the spring.
[0090] It is understandable that when there are at least two limiters 1200, the distance between two adjacent limiters 1200 is equal to the distance between two adjacent magnetic bases 3100.
[0091] The contents of this application are described in detail below with reference to specific embodiments. It should be noted that the following description is merely illustrative and not a specific limitation of this application.
[0092] This application relates to a spring conveying method, which is implemented based on a spring compression conveying assembly to complete the compression and conveying of the spring.
[0093] The spring delivery method includes the following workflow.
[0094] The spring enters the limiting groove and is located between two compression members 1300, which move closer to each other so that the spring is compressed in the limiting groove.
[0095] The base 1100 moves toward the spring conveying assembly 2000, and the feed end of the spring conveying assembly 2000 is inserted into the compression member 1300.
[0096] The compression members 1300 are spaced apart from each other, and the two ends of the spring abut against the spring conveying assembly 2000 so that the spring is transferred from the compression members 1300 to the spring conveying assembly 2000.
[0097] The base 1100 moves in the opposite direction to move away from the spring conveyor assembly 2000.
[0098] It should be noted that when the magnetic holder 3100 moves to the position of flipping and corresponding to the limiting member 1200, the limiting member 1200 rises, allowing the spring of the magnetic holder 3100 to enter the limiting groove. During the subsequent stroke, the distance between the magnetic holder 3100 and the limiting member 1200 remains constant, and the compression members 1300 move closer to each other to compress and clamp the spring. As the magnetic holder 3100 and the limiting member 1200 gradually move away from each other, the spring separates from the magnetic holder 3100, thereby transferring the spring from the magnetic holder 3100 to the limiting groove.
[0099] In some examples, when the feed end of the spring conveyor assembly 2000 enters the compressor 1300, the stop 1200 descends to avoid the feed end of the spring conveyor assembly 2000.
