[0022] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0023] Reference Figure 1~Figure 3 , which is an embodiment of the present invention, provides a tension spring assembly machine for a foot support, which is used to install a tension spring 5 on a foot support 2, wherein the foot support 2 has a first clamping portion 202 and a second clamping portion 203, and the two ends of the tension spring 5 are respectively clamped on the first clamping portion 202 and the second clamping portion 203, comprising: a frame 1, having a conveying groove 101, and the foot support 2 is slidably arranged in the conveying groove 101; a guide conveying member, which is arranged on the frame 1 and located above the foot support 2, and the tension spring 5 is suspended on the guide conveying member. On the conveying member, the guiding conveying member is used to drive the tension spring 5 to move with the foot support 2, and the guiding conveying member is used to guide one end of the tension spring 5 to be clamped on the first clamping portion 202; the mounting member 10 is arranged on the frame 1, and the mounting member 10 has a connecting portion 1005 and a guide groove 1003, the connecting portion 1005 is slidably arranged in the guide groove 1003, the connecting portion 1005 is inserted into the other end of the tension spring 5, and the connecting portion 1005 is used to guide the other end of the tension spring 5 to be clamped on the second clamping portion 203.

[0024] In the above scheme, during the initial preparation, a large number of foot supports 2 to be assembled are placed in turn into the conveying slot 101 of the frame 1 to ensure that the foot supports 2 can slide straightly in the slot. The tension spring 5 is suspended on the guide conveyor. After starting the assembly machine, the foot support 2 begins to slide in the conveying slot 101, and at the same time, the guide conveyor drives the tension spring 5 to move synchronously. When the foot support 2 and the tension spring 5 move to the appropriate position, the guide conveyor guides one end of the tension spring 5 to accurately snap onto the first snap-in portion 202 of the foot support 2. Subsequently, the connecting portion 1005 of the mounting member 10 slides in the guide slot 1003 and inserts the other end of the tension spring 5, and then guides this end of the tension spring 5 to snap onto the second snap-in portion 203 of the foot support 2, thereby completing a tension spring 5 assembly process on the foot support 2, and then repeating this process continuously.

[0025] The frame 1 provides a stable support structure for the entire assembly machine. The conveying groove 101 can ensure that the foot support 2 slides smoothly and prevent it from shaking or shifting during the sliding process, thereby ensuring the accuracy of assembly. The guide conveying member is located above the foot support 2 and is connected to the tension spring 5. The guide conveying member can stably drive the tension spring 5 when the foot support 2 moves, and can accurately guide one end of the tension spring 5 to dock with the first clamping portion 202 of the foot support 2. The connecting portion 1005 can slide flexibly in the guide groove 1003 to ensure the guidance of the clamping process of the other end of the tension spring 5.

[0026] The device eliminates the potential safety hazard caused by the spring 5 popping out when the spring 5 is manually assembled, thus ensuring the safety of the operator. The device greatly improves the assembly efficiency, overcomes the problem of slow manual assembly speed, meets the needs of large-scale production, effectively shortens the production cycle, and reduces production costs. The device also has high assembly accuracy, ensuring the accuracy and stability of the connection between the spring 5 and the foot support 2, thus improving product quality.

[0027] Furthermore, the middle part of the foot support 2 has a recessed portion 201 and a protruding portion 204, and the recessed portion 201 is slidably arranged in the conveying groove 101; the guiding conveying member includes: a guide rod 41, one end of the guide rod 41 is arranged on the frame 1, the guide rod 41 has a straight section 411 and an inclined section 412, the inclined section 412 is located on the side close to the mounting member 10, and one end of the tension spring 5 is slidably suspended on the guide rod 41; a crossbeam 9 is arranged on the other side of the guide rod 41, and the crossbeam 9 has a mounting groove 902; a shift rod 7 is slidably arranged on the crossbeam 9, the bottom end of the shift rod 7 is abutted against the foot support 2, and the top end of the shift rod 7 is connected to the tension spring 5, and after the foot support 2 moves along the conveying groove 101, it is used to drive the shift rod 7 to slide along the straight section 411 to the inclined section 412.

[0028] In the above scheme, first, the foot support 2 is placed in the conveying groove 101 through the concave portion 201 in the middle and starts to slide. One end of the tension spring 5 is suspended on the guide rod 41, and one end of the guide rod 41 is firmly fixed on the frame 1. When the foot support 2 moves along the conveying groove 101, the bottom end of the lever 7 keeps close contact with the foot support 2, and the top end thereof contacts the tension spring 5. As the foot support 2 moves, the lever 7 slides along the straight section 411 of the guide rod 41 toward the inclined section 412. During this process, the tension spring 5, pushed by the lever 7, gradually approaches the first clamping portion 202 of the foot support 2 along the guide rod 41 until the clamping is completed.

[0029] The recessed portion 201 of the foot support 2 cooperates with the conveying groove 101 to make the foot support 2 more stable and reduce shaking during the sliding process. The straight section 411 and the inclined section 412 of the guide rod 41 provide a clear path guide for the movement of the tension spring 5. The mounting groove 902 of the crossbeam 9 provides a stable mounting position for the lever 7, so that the lever 7 can slide smoothly on the crossbeam 9. The lever 7 can accurately transmit the movement of the foot support 2 to the tension spring 5 and guide the movement direction of the tension spring 5. The accuracy and reliability of the clamping of the tension spring 5 with the first clamping portion 202 of the foot support 2 are improved. The tension spring 5 has a clear guide during the movement process, which reduces the clamping deviation caused by human factors or other uncertain factors, improves the assembly quality and efficiency, and also reduces the failure rate during the assembly process.

[0030] Furthermore, the cross beam 9 has a notch 901 , and the notch 901 is located at one side of the mounting member 10 . After the lever 7 moves to the position of the mounting member 10 , the lever 7 is taken out through the notch 901 .

[0031] In the above scheme, during the assembly process, when the lever 7 reaches the position of the mounting member 10 along with the movement of the foot support 2, since the cross beam 9 is provided with a notch 901 on one side of the mounting member 10, the operator can easily remove the lever 7 from the cross beam 9 through the notch 901, thereby avoiding interference between the lever 7 during the subsequent engagement process between the tension spring 5 and the second engaging portion 203 of the foot support 2.

[0032] The notch 901 on the crossbeam 9 is located on one side of the mounting member 10, which matches the position and moving path of the lever 7, making it convenient for the operator to operate without affecting other structures and functions of the entire assembly machine. The operator can easily remove the lever 7, reducing the obstruction that may be caused by the lever 7 near the installation area, further improving the assembly efficiency, and reducing the risk of assembly errors that may be caused by inconvenient operation.

[0033] Furthermore, the mounting member 10 includes: a sliding seat 1001, which is slidably arranged on the frame 1; an arc guide rail 1002, which is arranged on the sliding seat 1001, and a guide groove 1003 is arranged on the arc guide rail 1002; a connecting rod 1004, which is slidably arranged on the arc guide rail 1002, and the connecting part 1005 is located at one end of the connecting rod 1004 away from the arc guide rail 1002. After the tension spring 5 is located in the bevel section, the sliding seat 1001 moves toward the direction of the tension spring 5 to drive the connecting part 1005 to insert into the other end of the tension spring 5.

[0034] In the above scheme, when the tension spring 5 is ready on the inclined section 412 of the guide rod 41, the sliding seat 1001 starts to slide on the frame 1 toward the tension spring 5. Since the connecting rod 1004 can slide on the arc-shaped guide rail 1002, and the connecting portion 1005 is located at one end of the connecting rod 1004, as the sliding seat 1001 moves, the connecting portion 1005 is accurately inserted into the other end of the tension spring 5. Then, through the guidance of the guide groove 1003 on the arc-shaped guide rail 1002 to the connecting portion 1005, this end of the tension spring 5 can be smoothly clamped to the second clamping portion 203 of the foot support 2.

[0035] The sliding connection between the sliding seat 1001 and the frame 1 is of high precision, ensuring the stability of the sliding process. The arc design of the arc guide rail 1002 is adapted to the installation position relationship of the tension spring 5 and the foot support 2, and can provide a suitable moving path for the connecting part 1005. The connecting rod 1004 slides freely on the arc guide rail 1002, and the connecting part 1005 is firmly connected to the connecting rod 1004, ensuring that it will not loosen or fall off during the assembly process.

[0036] The arc guide rail 1002 and the guide groove 1003 can better adapt to the position and angle changes of the tension spring 5 in different installation stages, effectively reduce the error in the clamping process, improve the success rate of assembly and the consistency of the product, and ensure the assembly quality.

[0037] Furthermore, the mounting member 10 also includes: a top rod 11, which is arranged on the frame 1; a telescopic rod 12, which is arranged at one end of the top rod 11 close to the inclined section 412, and a spring 13 is sleeved on the outer side of the telescopic rod 12, and the piston end of the telescopic rod 12 abuts against the inclined section 412; a baffle 14, which is arranged on the piston end of the telescopic rod 12, and the baffle 14 is used to prevent the tension spring 5 from falling off from the inclined section 412.

[0038] In the above solution, when the tension spring 5 is located in the inclined section 412 waiting for further assembly, the spring 13 sleeved on the outer side of the telescopic rod 12 provides elastic force, so that the piston end of the telescopic rod 12 stably abuts against the inclined section 412. The baffle 14 installed at the piston end of the telescopic rod 12 effectively prevents the tension spring 5 from accidentally falling off from the inclined section 412, ensuring that the tension spring 5 is fixed in position while waiting for installation.

[0039] The top rod 11 provides a reliable support point for the entire structure. The elastic coefficient of the spring 13 of the telescopic rod 12 is carefully selected to ensure sufficient elastic force to make the telescopic rod 12 abut against the inclined section 412, while not causing damage to other components due to excessive elastic force. The size and shape of the baffle 14 match the positional relationship between the tension spring 5 and the inclined section 412, and can completely cover the direction in which the tension spring 5 may fall off.

[0040] The tension spring 5 is effectively prevented from accidentally falling off at the inclined section 412, ensuring the continuity and stability of the assembly process. The problem of installation failure or the need for readjustment due to the change in the position of the tension spring 5 is avoided, the reliability of the assembly process is improved, the errors and interruptions in the assembly process are reduced, and the production efficiency is improved.

[0041] Furthermore, it also includes: a clamping conveyor 8, which is arranged at the bottom of the frame 1. After the foot support 2 moves to the inclined section 412, the clamping conveyor 8 is used to clamp the foot support 2 on which the tension spring 5 is to be installed.

[0042] In the above scheme, after the foot support 2 moves to the inclined section 412 with the conveyor belt 6, the clamping conveyor 8 automatically starts and starts working. It clamps the foot support 2 waiting for the installation of the tension spring 5 through a specific clamping mechanism. During the process of clamping and installing the tension spring 5 and the foot support 2, the clamping conveyor 8 continues to maintain the clamping state to ensure that the foot support 2 will not be displaced due to the elastic force of the tension spring 5 or other external forces, and to ensure that the tension spring 5 can be accurately clamped to the clamping part of the foot support 2. The clamping conveyor 8 is located at the bottom of the frame 1. The clamping mechanism adopts suitable clamping materials and structures, which can apply sufficient clamping force without damaging the foot support 2, thereby ensuring the position stability of the foot support 2 when installing the tension spring 5. By clamping the foot support 2, the failure of clamping caused by the shaking or displacement of the foot support 2 is effectively reduced, thereby improving the assembly quality and efficiency, ensuring the smooth progress of the entire assembly process, and reducing the defective rate.

[0043] Furthermore, it also includes: a conveyor belt 6, which is arranged on the frame 1, the conveyor belt 6 has a limiting portion 601, the foot support 2 is arranged on the limiting portion 601, and the conveyor belt 6 is used to drive the foot support 2 to move along the conveying trough 101.

[0044] In the above scheme, before the assembly starts, the foot support 2 is placed on the limit portion 601 of the conveyor belt 6. After the assembly machine is started, the conveyor belt 6 starts to run, and uses its own friction or other transmission methods to drive the foot support 2 to move along the conveying trough 101. During the movement, the foot support 2 will pass through various links of the tension spring 5 installation in sequence, such as the installation of the tension spring 5 under the cooperation of the guide conveying member and the installation member 10 and other related components. After the installation is completed, the conveyor belt 6 continues to transport the assembled foot support 2 to the next process or collection area.

[0045] There is appropriate friction between the conveyor belt 6 and the foot support 2, which can stably transport the foot support 2 without damaging the surface of the foot support 2. The design of the limiter 601 is key, which can accurately limit the position of the foot support 2, prevent the foot support 2 from deviating or misaligned during the transportation process, and ensure that the foot support 2 moves along the predetermined path. The automatic transportation of the foot support 2 is realized, which greatly improves the production efficiency. The limiter 601 ensures the accuracy and stability of the transportation of the foot support 2, reduces the need for manual intervention, reduces the errors that may be caused by manual operation, creates good conditions for the precise installation of the tension spring 5, and improves the consistency of product quality.

[0046] Furthermore, it also includes: a sensor 15, which is arranged on the sliding seat 1001, and the sensor 15 is used to sense the position of the foot support 2.

[0047] In the above scheme, during the assembly process, when the foot support 2 moves to the corresponding position along with the conveyor belt 6, the sensor 15 on the sliding seat 1001 of the mounting member 10 starts to work. The sensor 15 senses the position of the foot support 2 by detecting specific signals of the foot support 2, such as optical signals, electromagnetic signals, etc. Once the sensor 15 senses that the foot support 2 has reached a suitable installation position, the sensor 15 immediately transmits the signal to the control system of the assembly machine. Based on the signal, the control system accurately controls the mounting member 10 and other related components to perform subsequent installation operations of the tension spring 5, thereby ensuring the timeliness and accuracy of the installation.

[0048] The sensor 15 is mounted on the sliding seat 1001, and its position corresponds to the moving path and installation position of the foot support 2. The sensor 15 is connected to the control system through a stable and reliable signal transmission line to ensure fast and accurate signal transmission. By timely and accurately sensing the position of the foot support 2, installation errors caused by inaccurate position of the foot support 2 are avoided, the assembly process is optimized, the assembly efficiency and product quality are further improved, and defective products caused by manual judgment errors are reduced.

[0049] Furthermore, it also includes: a support rod 3, which is obliquely arranged on the frame 1, and a mounting hole 301 is provided between the support rod 3 and the guide rod 41, and the mounting hole 301 is used to provide a space for mounting the tension spring 5 on the guide rod 41.

[0050] In the above scheme, when installing the tension spring 5 on the guide rod 41, the installer can use the space provided by the mounting hole 301 between the support rod 3 and the guide rod 41 to operate. The tension spring 5 is installed on the guide rod 41 through the mounting hole 301 from a suitable angle. This space provides convenience for the installation operation, making the installation process of the tension spring 5 smoother. The shape of the mounting hole 301 and the surrounding space layout fully consider the principles of ergonomics, making it convenient for installers to operate. It facilitates the installation operation of the tension spring 5 on the guide rod 41, and improves the convenience and efficiency of the installation. It reduces the difficulties that may be caused to the installers due to insufficient operating space, optimizes the installation process, improves the work efficiency in the assembly preparation stage, and also helps to improve the fluency of the entire assembly process. Furthermore, the lever 7 has an arc-shaped portion 701 , which is slidably disposed on the guide rod 41 , and the arc-shaped portion 701 is used to push the tension spring 5 to move along the guide rod 41 .

[0051] In the above solution, the stability and smoothness of the movement of the tension spring 5 on the guide rod 41 are ensured. Through the push of the arc portion 701, the tension spring 5 can move more accurately along the predetermined path of the guide rod 41, effectively reducing the possibility of the tension spring 5 getting stuck or deviating from the path, improving the reliability and efficiency of the assembly process, and helping to improve product quality.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
