Description

Technical Field

[0001] The present invention relates to a device for carrying a spring, an apparatus including such a device, and a method of using such a device and apparatus. Background Technology

[0002] Many devices require one or more springs, and the methods and equipment used to assemble such devices require precise and repeatable handling, movement, and placement of these springs. Devices that include one or more springs in their components include drug injection devices. Such devices may include springs to facilitate various functions of the device, including the operation of the drug delivery mechanism, or to deploy one or more safety features before, during, or after the drug delivery process.

[0003] If springs are stored or transported in bulk, they can easily become tangled together, and separating them can be difficult and time-consuming when they need to be assembled into a device being manufactured, resulting in inefficiency and high costs during the manufacturing process. In mass production, errors in the assembly line or situations requiring production line stoppages (e.g., due to machine blockages or malfunctions) are undesirable, as they lead to lost production time, reduced productivity and product output, and impact manufacturing and product costs.

[0004] Therefore, in the manufacturing process of a product containing one or more springs, it is desirable to provide a device that facilitates the repeated and reliable handling, transport and placement of the springs used in such a process, and / or helps to protect and ensure the integrity of the springs.

[0101] Figures 1 to 4 A spring bracket 10 according to an embodiment of the present invention is shown, comprising a hollow body 11 having sidewalls 12 formed in a tubular shape and defining an inner cavity 13. The hollow body 11 includes an opposing first proximal end 14 and a second distal end 15. The hollow body 11 is circular in cross-section and includes a central axis X. A first opening 16 is provided at the first proximal end 14. In an exemplary embodiment, a second opening 17 is provided at the second distal end 15. The inner cavity 13 can be accessed through the first and second openings 16, 17.

[0102] The spring bracket 10 includes two deflectable members 18, which in the illustrated exemplary embodiment include resilient arms 18. The resilient arms 18 are disposed in a sidewall 12 of the hollow body 11. The resilient arms 18 are disposed within holes 19 in the sidewall 12, providing space 20 around the resilient arms 18. The resilient arms 18 are connected to the sidewall 12 at their respective fixed ends 21. The resilient arms 18 are configured to bend around the fixed ends 21. Each resilient arm 18 has a free end 22 at its end opposite the fixed end 21. The resilient arms 18 include an actuating feature 23 for engaging with an actuator 30 (described in more detail below), operable to move the resilient arm 18 in use. In the illustrated exemplary embodiment, the actuating feature includes a head 23 disposed at the free end 22 of each resilient arm 18.

[0103] The head 23 includes a contact surface 24 extending from the distal portion of the free end 22 of the corresponding elastic arm 18. The contact surface 24 includes a bevel extending inward toward the central axis XX and set at an acute angle θ1 relative to the central axis XX. The contact surface 24 can be configured at an angle θ1 between 15 and 55 degrees relative to the central axis XX, and can be, for example, between 20 and 50 degrees, between 25 and 45 degrees, between 30 and 40 degrees, and approximately 35 degrees.

[0104] The resilient arm 18 includes a retaining structure that, in use, when the coil spring C is disposed within the cavity 13, engages with the coil spring C and holds the coil spring C in place within the cavity 13. The retaining structure includes a protruding element 25 extending from the respective resilient arm 18 and inwardly toward the central axis XX of the hollow body 11. The protruding element 25 is spaced apart from a respective head 23 along the respective resilient arm 18, such that the retaining structure also includes a notch 26 defined between the head 23 and the protruding element 25 on each resilient arm 18.

[0105] The elastic arm 18 extends substantially parallel to the central axis XX of the hollow body 11. The elastic arm 18 is movable by elastic deflection. In the first position, the elastic arm 18 is in a relaxed state, extending substantially parallel to the central axis XX of the hollow body 11 and substantially flush with the side wall 12 of the hollow body 11. The elastic arm 18 can deflect away from the central axis XX to a second position. In the second position, the elastic arm elastically deforms.

[0106] When the corresponding elastic arm 18 is in the first relaxed position, the innermost portion of the protruding element 25 can be radially positioned inside the inner surface plane of the sidewall 12 of the hollow body 11. At least in the first relaxed position of the elastic arm 18, the head 23 can extend inward toward the central axis XX further inward than the protruding element 25 of each elastic arm 18. This can be, for example, in... Figure 4 As seen below, the distance D1 between the outer surface of the hollow body 11 and the innermost part of the head 23 is greater than the distance D2 between the outer surface of the hollow body 11 and the innermost part of the protruding element 25. For example, in the first relaxed position and the second elastically deformed position of the elastic arm 18, the head 23 extends inward toward the central axis XX more than the protruding element 25 of each elastic arm 18. This configuration will allow the coil spring C to be inserted into the cavity 13 when the elastic arm 18 is in the second deformed position, and the protruding element to be away from the coil spring, but even when the elastic arm 18 is in the second deformed position, the coil spring C cannot extend beyond the head 23. This will be seen below with reference to Figures 7A to 7B. Figure 8B To be explained in more detail. However, the invention is not limited to this configuration, and in other embodiments, at least in the first relaxed position of the elastic arm 18, the head 23 may extend inward toward the central axis XX by a smaller distance than the protruding element 25 of each elastic arm 18.

[0107] The hollow body 11 includes a continuous annular portion 27 at its farthest region at its second end. The continuous annular portion 27 extends completely around the periphery of the hollow body 11 and is located closer to the second end than the elastic arm 18.

[0108] A flange 28 is disposed on the outer surface of the hollow body 11 and extends radially outward in a direction perpendicular to the central axis XX. In the exemplary embodiment shown, the flange 28 is located in the nearest side region of the first proximal end of the hollow body 11.

[0109] When used during manufacturing and assembly, the spring holder 10 can be used to perform at least one of receiving, holding, conveying, and discharging the helical spring C. Such a manufacturing process may include, for example, a method of manufacturing a drug delivery device, where the helical spring C may be needed as a biasing member to actuate the drug delivery mechanism or to actuate the needle safety mechanism after the drug has been delivered. Referring now to Figure 5A- Figure 5E and Figures 6A-6E Describe the use of the spring bracket 10.

[0110] The spring bracket 10 is intended for use in conjunction with an actuator 30 operable to move the elastic arm 18. The actuator 30 and the spring bracket 10 may comprise two components of the device of the present invention. Such a device may include a spring bracket assembly and may be part of an assembly system or device for medical devices, and may be part of an assembly and / or manufacturing device / system for pharmaceutical injection devices. However, the invention is not limited to the field of medical devices, but is applicable to any technical field that may require the handling and delivery of one or more springs.

[0111] Actuator 30 includes a rod having a central axis YY. Actuator 30 is configured to slide within the cavity 13 of the hollow body 11. In the exemplary embodiment shown, the hollow body 11 has a cylindrical cross-section, and actuator 30 is a cylindrical rod with an outer diameter slightly smaller than the inner diameter of the cavity 13. Actuator 30 includes a distal end 31 and a curved outer surface 32. Actuator 30 includes a chamfered surface 33 located between the distal end 31 and the side surface 32. Chamfered surface 33 extends at an acute angle θ2 relative to the central axis YY of the actuator, as shown in FIG5A. For example, chamfered surface 33 can be configured to extend at an acute angle θ2 relative to the central axis YY of the actuator, which is substantially the same angle θ1 as the angle θ1 at which the inclined contact surface 24 of head 23 extends relative to the central axis XX of hollow body 11. This can allow for improved engagement between actuator 30 and head 23 during use and reduce wear on the respective contact surfaces during repeated use. Angles θ2 and / or θ1 can be between 10 and 50 degrees, between 15 and 45 degrees, between 20 and 40 degrees, between 25 and 35 degrees, and around 30 degrees.

[0112] Figure 5A- Figure 5E The method steps for inserting the helical spring C into the spring bracket 10 are shown. In the first step shown in Figure 5A, the actuator 30 is oriented toward the second end 15 of the hollow body 11. The central axis YY of the actuator 30 is aligned and coaxial with the central axis XX of the hollow body 11.

[0113] In the next step shown in Figure 5B, as indicated by arrow B, the actuator 30 moves axially toward the spring bracket 10, and the distal end 31 of the actuator 30 is inserted into the second opening 17 in the second end 15 of the hollow body 11. The actuator 30 first passes through the annular portion 27 of the hollow body 11. This helps to align the actuator 30 within the hollow body 11, ensuring that the axes X and Y of the hollow body 11 and the actuator 30 remain coaxial. The continuous annular portion 27 of the hollow body 11 also serves to provide structural strength to the spring bracket 10 around the elastic arm 18, and helps the spring bracket 10 maintain its shape and prevent damage due to repetitive handling during its manufacture and assembly.

[0114] Actuator 30 then engages the resilient arms 18. Specifically, the chamfered surface 33 of actuator 30 abuts against the inclined contact surface 24 of the head 23 of each resilient arm 18. Actuator 30 continues to move axially toward spring bracket 10 until it reaches the loaded position shown in FIG. 5B. In this position, actuator 30 has elastically deflected the resilient arm 18 radially outward, as indicated by arrow D in FIG. 5B. The resilient arm 18 bends about its corresponding fixed end 21. Thus, the retaining structure of the protruding element 25 and the notch 26 of each resilient arm 18 also moves outward with the movement of the resilient arm 18, and moves outward from the axial protrusion of the inner surface of the sidewall 12 of the hollow body 11 defining the cavity 13. In this disclosure, it should be understood that the terms “inward” and “outward” are used generally relative to the body of spring bracket 10, such as relative to the central axis XX or relative to the hollow body 11 of spring bracket 10. Therefore, the outward movement of the elastic arm 18 is intended to be radially outward from the central axis XX.

[0115] In the next step shown in Figure 5C, the helical spring C is inserted into the inner cavity 13 through the first opening 16 at the first end 14 of the hollow body 11, as indicated by arrow E. The outer diameter of the helical spring C is slightly smaller than the inner diameter of the inner cavity 13. Because the elastic arms 18 are in a radially outward deflected position, when the helical spring C is inserted into the inner cavity 13, the retaining structure on each elastic arm 18 moves away from the helical spring C and allows the helical spring C to fall into the inner cavity 13 until it abuts the actuator 30, as shown in Figure 5D.

[0116] In step 5E, the actuator 30 then moves axially away from the spring holder 10, as indicated by arrow F. This disengages the actuator 30 from the elastic arms 18, and thus, due to the elastic recovery of the material of the elastic arms 18, the elastic arms 18 then move back to their first rest position, as indicated by arrow G. When the elastic arms 18 reach the first relaxed position, the retaining structure engages with the helical spring C. That is, the end coils of the helical spring C are received within the notches 26 of each elastic arm 18, and the protruding elements 25 are received between the end coils of the helical spring C. The helical spring C is thus securely held within the spring holder 10 and can be conveyed within the spring holder 10 to the location where the helical spring C will be used and to the manufacturing / assembly equipment.

[0117] Now refer to Figures 6A-6E The process of removing the helical spring C from the spring holder 10 is described. Before the removal process begins, and in the step preceding the assembly or manufacturing process requiring the helical spring C, the spring holder 10 is inverted from the orientation shown in the insertion method step, such that the spring holder 10 is oriented with the first end 14 lowest and the second end 15 highest. The spring holder 10 is also positioned directly above the storage location of the helical spring C for the corresponding assembly / manufacturing process. For example, the spring holder 10 can be vertically aligned for the removal process. This helps the helical spring C to be removed from the spring holder 10 uniformly and vertically, i.e., in a direction aligned with the central axis XX of the hollow body 11.

[0118] The retrieval process is generally the reverse of the insertion process described above. Figure 6A In the first step shown, the spring bracket 10 is oriented substantially vertically with the first end 14 being the lowest point. The actuator 30 is vertically positioned above and moves downward toward the second end 15 of the hollow body 11. The central axis YY of the actuator 30 is aligned and coaxial with the central axis XX of the hollow body 11.

[0119] exist Figure 6B In the next step shown, as indicated by arrow B, the actuator 30 moves axially toward the spring bracket 10, and the distal end 31 of the actuator 30 is inserted into the second opening 17 in the second end 15 of the hollow body 11. The actuator 30 first passes through the annular portion 27 of the hollow body 11, which also helps to align the actuator 30 within the hollow body 11 so that the axes XX and YY of the hollow body 11 and the actuator 30 remain coaxial.

[0120] Actuator 30 then engages the resilient arm 18. Specifically, the chamfered surface 33 of actuator 30 abuts against the inclined contact surface 24 of the head 23 of each resilient arm 18. Actuator 30 continues to move axially toward spring bracket 10 until it reaches... Figure 6BThe release position is shown. In this position, the actuator 30 has elastically deflected the elastic arms 18 radially outward, as indicated by arrow D. The elastic arms 18 bend about their respective fixed ends 21. Consequently, the protruding element 25 and the retaining structure of the notch 26 of each elastic arm 18 also move outward and disengage from the coil spring C.

[0121] exist Figure 6C In the next step shown, since the elastic arms 18 are in a radially outward deflected position, the retaining structures on each elastic arm 18 are away from the coil spring C. Therefore, the coil spring C, under its own weight, falls freely out of the inner cavity 13 through the first opening 16 at the first end 14 of the hollow body 11. The coil spring C falls into the desired position outside the spring bracket 10, so that the coil spring C is completely removed from the spring bracket, as shown. Figure 6D As shown.

[0122] In step 6E, the actuator 30 then moves axially away from the spring holder 10, as indicated by arrow F. This disengages the actuator 30 from the elastic arm 18, and thus, due to the elastic recovery of the material of the elastic arm 18, the elastic arm 18 then moves back to its first rest position, as indicated by arrow G. The spring holder 10 can then be collected and returned for reuse in subsequent spring insertion and removal processes.

[0123] During insertion and removal, the spring bracket 10 can be precisely aligned with the position where the coil spring C will be inserted / removed, allowing the coil spring C to be efficiently delivered as needed without obstructing the end of the spring bracket 10 or the equipment into which the coil spring C will be discharged. In this way, manufacturing errors and / or production downtime for correcting errors can be reduced or avoided. The flange 28 can help avoid such misalignment problems by providing positioning guidance for the spring bracket in use. For example, before inserting or removing the coil spring C, the flange 28 can be located within a recess of a corresponding shape in the assembly / manufacturing equipment, which allows the central axis XX of the hollow body 11 to be coaxial with the central axis of the coil spring C.

[0124] Another embodiment of the spring bracket 10 of the present invention is shown in Figures 7A-10B, and the same features as the previously described embodiment of the spring bracket 10 retain the same reference numerals, and will not be described in detail again.

[0125] The spring bracket 10 shown in Figures 7A-10B has a differently configured head 23 at the free end 22 of the resilient arm 18. Similar to the previous embodiment, the head 23 includes an inclined contact surface 24. However, the head 23 also includes a more square abutment step 34. The abutment step 34 extends from the inclined contact surface 24 to the inner surface of the corresponding resilient arm 18. In the exemplary embodiments of Figures 7A-10B, the abutment step 34 faces the first end 14 of the hollow body 11. In the relaxed position of the resilient arm 18 (see Figure 7A-10B)... Figure 8A and Figure 8B (As shown in Figures 10A and 10B), the elastic arm 18 is substantially parallel to the central axis XX of the hollow body 11 and substantially flush with the sidewall 12 of the hollow body 11, and the abutment surface 34 extends in a plane substantially perpendicular to the central axis XX of the hollow body 11. The equivalent abutment step surface of the first embodiment is at an angle, for example, an acute angle, relative to the central axis XX of the hollow body 11.

[0126] The following will refer to Figure 7A- Figure 8B The function of the abutment step 34 is described. Figure 7A corresponds to the operational steps of Figure 5D of the aforementioned embodiment, where the helical spring C has been inserted into the inner cavity 13 of the hollow body 11, and the actuator 30 is still in the loaded position with the elastic arm 18 radially deflected outwards. Figure 7B shows an enlarged view of a portion of Figure 7A, which more clearly shows the head 23 of the elastic arm 18 and the abutment step 34, as well as the actuator 30 with its chamfered surface 33. During the insertion of the helical spring C into the inner cavity 13, the helical spring C can fall freely into the inner cavity 13. The actuator 30 deflects the elastic arm 18 outwards, causing the protruding element 25 to move out of the helical spring C. That is, the elastic arm 18 can be fully deflected radially outwards by the actuator 30, such that the innermost part of the protruding element 25 is arranged radially outwards on the inner surface plane of the side wall 12 of the hollow body 11. In this way, the helical spring C can move freely over the protruding element 25. This is specifically shown in Figure 7B by line L2, which extends parallel to the central axis XX of the hollow body 11 and intersects the innermost radial portion of the protruding element 25. Line L2 can be seen to be positioned radially outward from the outermost radial portion of the helical spring C.

[0127] At the deflection position of the elastic arm 18, the head 23 and the abutment step 34 extend radially inward beyond the radial innermost portion of the corresponding protruding element 25. This is particularly visible in Figure 7B via line L1, which extends parallel to the central axis XX of the hollow body 11 and intersects the radial innermost portion of the head 23 / abutment step 34. Line L1 can be seen to be positioned radially inside line L2.

[0128] It can also be seen that line L1 is located radially inside the outermost radial portion of the helical spring C. Therefore, even in the deflected position of the elastic arm 18, the helical spring C cannot pass through the head 23 of the elastic arm, but is blocked by contact with the abutting surface 34 of the corresponding elastic arm 18.

[0129] In the embodiments shown in Figures 7A and 7B, in the deflected position of the elastic arm 18, the distal surface 31 of the actuator 30 is substantially flush with the abutment surface 34 relative to the direction perpendicular to the central axis XX of the hollow body 11. Therefore, insertion of the helical spring C can involve the helical spring C abutting against the abutment surface 34 and the distal surface 31 of the actuator 30. Alternatively, in the deflected position of the elastic arm 18, the distal surface 31 of the actuator 30 may not be flush with the abutment surface 34, such that insertion of the helical spring C can involve the helical spring C abutting only against the abutment surface 34 without contacting the distal surface 31 of the actuator 30.

[0130] Once the actuator 30 moves away from the spring bracket 10, due to the elastic relaxation of the material of the elastic arm 18, the elastic arm 18 moves back to the first relaxed position, and the coil spring C remains stationary on the abutment surface 34. Figure 8A and Figure 8B As shown. Figure 8A Equivalent to the aforementioned implementation plan Figure 5E The operating steps are as follows: the helical spring C has been inserted into the inner cavity 13 of the hollow body 11, and the actuator 30 has been removed from engagement with the elastic arm 18. Figure 8B It shows Figure 8A A magnified view of a portion of the image. Also in this position, the retaining structure of the elastic arm 18 engages the coil spring C to hold the coil spring C within the inner cavity 13 during subsequent movement of the spring bracket 10.

[0131] The process of removing the helical spring C is shown in Figures 9A to 10B. Figure 9A corresponds to the aforementioned embodiment. Figure 6D The operating procedure is as follows: the helical spring C has been removed from the inner cavity 13 of the hollow body 11, and the actuator 30 is still in the removed position, in which the elastic arm 18 is radially deflected outward. Figure 9B shows an enlarged view of a portion of Figure 9A, which more clearly shows the head 23 and abutment step 34 of the elastic arm 18, and the actuator 30 with its chamfered surface 33.

[0132] Once the actuator 30 moves away from the spring bracket 10, due to the elastic relaxation of the material of the elastic arm 18, the elastic arm 18 moves back to the first relaxed position, as shown in Figure 10A. Figure 10A corresponds to the aforementioned embodiment. Figure 6EThe operational steps are as follows: the helical spring C has been removed from the inner cavity 13 of the hollow body 11, and the actuator 30 has been removed from engagement with the elastic arm 18. The spring holder 10 can then be collected and returned for reuse in subsequent spring insertion and removal processes. Figure 10B shows an enlarged view of a portion of Figure 10A.

[0133] As shown in Figures 7B and 9B, when the actuator 30 is inserted into the spring bracket 10 in the loaded and / or unloaded position, the elastic arm 18 deflects radially outward by an angle θ3 from the relaxed position. In the relaxed position, the elastic arm 18 is substantially parallel to the central axis XX of the hollow body 11 and substantially flush with the sidewall 12 of the hollow body 11. The angle θ3 can vary within the scope of the invention and / or in any embodiment of the invention described herein, and can vary according to various dimensions (e.g., the length of the elastic arm 18, the distance the head 23 extends inward from the elastic arm 18, the diameter of the hollow body 11, etc.). However, the angle θ3 can be between approximately 4 and 12 degrees, between 6 and 10 degrees, and around 8 degrees. This allows sufficient deflection of the elastic arm 18 to achieve the above-described function without causing excessive fatigue to the material of the elastic arm 18 and / or the hollow body 11. In other words, the elastic arm 18 can repeatedly deflect elastically and return to the same relaxed position without reaching the elongation limit of the spring bracket 10 material, which affects the elastic arm 18's ability to return itself to the intended first relaxed position. Factors influencing the desired elastic performance of the elastic arm 18 include its length, thickness, and width dimensions, as well as its elastic modulus, elastic limit, and toughness (resistance during rapid deformation). In any embodiment of the invention described herein, the elastic modulus can range from 1800 to 2500 MPa, and the elastic limit can be 40 to 80 MPa. Furthermore, the toughness of the elastic arm 18 can be 150 to 300 J / m. 2 In use, in order to allow for repeated elastic deformation and limit the aging effects on the material of the elastic arm 18, the arm can be deflected to only 40-80% of its maximum elastic limit.

[0134] Figure 9B also shows the lateral outward deflection distance d1. This is the distance by which the elastic arm 18 deflects outward from the relaxed position in the deflection position, where the outer surface of the elastic arm 18 is flush with the outer surface of the sidewall 12 of the hollow body 11. This deflection distance d1 can vary within the scope of the invention and / or in any embodiment of the invention described herein, but can be between 1 mm and 4 mm, between 1 mm and 3 mm, between 1 mm and 2 mm, and around 1.5 mm.

[0135] The embodiment of the spring bracket 10 shown in Figures 7A to 10B includes a tapered region 16A at a first opening 16 at the first end 14. This facilitates guiding the helical spring C into the first opening 16 during the insertion step described above. This feature may optionally be applied to and provided to any embodiment of the invention described herein.

[0136] The above describes an exemplary embodiment of a spring bracket device including a spring holder 10 and an actuator 30. Variations of the above-described spring bracket device may include means for facilitating the removal of the coil spring C from the spring holder 10. (Refer to...) Figures 6A-6E Describe this variant. (Refer to the above reference.) Figures 6A-6E During the removal process, in step 6C, once the elastic arm 18 is in the radially outward deflected position and the retaining structure on each elastic arm 18 disengages from the coil spring C, the coil spring C falls out of the inner cavity 13 under its own weight through the first opening 16 at the first end 14 of the hollow body 11. In a variation of the above device, the device may include an airflow source or air jet A to generate an airflow through the inner cavity 13, thereby blowing the coil spring C out of the spring holder 10. The actuator 30 may include an air passage 35 extending therethrough, having at least one open end at the distal end 31 of the actuator 30, and the other end of the air passage 35 being connected to or connectable to the compressed air source A. In use, when the actuator 30 moves the elastic arm 18 to the deflected position, the air source A may be connected or turned on to deliver airflow through the air passage 35 (in Figure 6C (As indicated by arrow A) and flows out from the distal end 31 of actuator 30. The airflow can then drive the helical spring C and force it away from spring bracket 10.

[0137] The actuator 30 may include a plurality of air passages 35 extending therethrough, and / or the actuator 30 may include a plurality of air passage outlets 36 located at the distal end 31 of the actuator 30. The one or more air passages 35 and / or air outlets 36 may be substantially parallel to the central axis YY of the actuator 30. Alternatively or additionally, one or more air outlets 36 and / or air passages 35 may be oriented at an angle relative to the central axis YY of the actuator 30. In the latter case, the angled air outlets 36 / passages 35 may cause airflow to impinge on the coil of the helical spring C, thereby causing the helical spring C to displace from the spring holder 10. In embodiments with a central axial airflow passage 35 / outlet 36, turbulence of the airflow through the helical spring can still cause sufficient airflow to impinge on the coil of the helical spring C, thereby causing the helical spring C to displace from the spring holder 10.

[0138] The spring bracket 10 and the equipment including the spring bracket 10 and the actuator 30 may be part of a larger assembly system or equipment for manufacturing devices comprising one or more helical springs C. Such a system may include multiple assembly machines or stations. Such assembly machines / stations may be configured as a continuous process and two or more independent processes. Figure 11 An exemplary assembly system 50 is schematically illustrated. Assembly system 50 includes a coil spring manufacturing system, generally referred to as 51. The coil spring manufacturing system 51 may include a winding station 52 for manufacturing coil springs C, and a heating station 53, in which the wound spring is heated to temper the spring material. The heated coil spring is then supplied to a cooling station 54 to cool the coil spring. Thereafter, a conveyor belt 55 conveys the cooled coil spring C to an insertion station 56, which includes a device with an actuator 30, and a spring holder 10 may be disposed at this station. At the insertion station 56, the actuator 30 and the spring holder 10 are operated as described above to insert the coil spring C into the spring holder 10. The spring holder 10, holding the coil spring C, is then conveyed to a removal station 57. At the removal station 57, the actuator 30 and the spring holder 10 are operated as described above to remove the coil spring C from the spring holder 10 for subsequent assembly steps using the coil spring C.

[0139] The configuration and arrangement of the protruding elements 25 on the elastic arm 18 can vary within the scope of the invention, and such variations within the scope of the invention and / or all embodiments described herein are... Figures 12 to 14 The example shown is a non-exhaustive one.

[0140] Figure 12 A schematic cross-sectional view of one embodiment configuration is shown, illustrating opposing elastic arms 18 in a relaxed state. Each elastic arm includes a head 23 and a plurality of axially spaced protrusions 25. The protrusions 25 of one elastic arm 18 are aligned in the axial direction of the spring bracket 10 with corresponding protrusions 25 of the opposing elastic arm 18. This is indicated by a reference line ZZ extending in a direction perpendicular to the axis XX of the spring bracket 10 through each protrusion 25 of one elastic arm 18 and through the corresponding protrusions 25 on the opposing elastic arms 18. When the coil spring C is held within the spring bracket 10, this helps to securely hold the coil spring C with minimal axial movement by facilitating the opposing protrusions 25 to abut and clamp the area of ​​the coil spring C. This arrangement may optionally be applied to embodiments of the spring bracket 10 of the invention comprising two or more elastic arms 18.

[0141] exist Figure 12In one embodiment, the head 23 of one elastic arm 18 is also aligned with the corresponding head 23 of the opposing elastic arm 18 in the axial direction of the spring bracket 10. This is indicated by a reference line WW, which extends through the head 23 of one elastic arm 18 in a direction perpendicular to the axis XX of the spring bracket 10, and extends through the corresponding head 23 on the opposing elastic arm 18. This helps to ensure precise and simultaneous deflection of each elastic arm 18 when actuated by the actuator 30 as described above.

[0142] exist Figure 12 In this implementation, the dimensions of the plurality of protruding elements 25 on each elastic arm 18 increase toward the free end 22 of each elastic arm 18. That is, the distance by which each protruding element 25 protrudes inward toward the central axis XX of the spring bracket 10 increases as it gets closer to the free end 22 of the elastic arm 18. This is illustrated by a line L3 aligned with the innermost portion of each protruding element 25, which is angled inward toward the central axis XX in the direction toward the free end 22 of the elastic arm 18. This can help to securely hold the helical spring C within the spring bracket 10, because larger, more inwardly extending protruding elements 25 can be positioned toward the free end 22 of the elastic arm, but when actuated by the actuator 30 as described above, the distance by which the free end 22 is laterally deflected outward is greater than the area spaced between each elastic arm 18 and the free end 22, the larger protruding elements 25 are still large enough to move outward to allow the helical spring C to be inserted.

[0143] Figure 13 A schematic cross-sectional view of another embodiment configuration is shown, similar to... Figure 12 And similar features retain the same reference numerals. Each of the opposing elastic arms 18 includes a head 23 and a plurality of protruding elements 25 spaced apart along the axial direction of each elastic arm. Figure 13 The difference in the embodiment is that the protruding element 25 of one elastic arm 18 is not aligned axially with the corresponding protruding element 25 of the opposing elastic arm 18 in the spring bracket 10, but is offset relative to the corresponding protruding element 25 of the opposing elastic arm 18 in the axial direction of the spring bracket 10. This is represented by a reference line VV, which extends through each protruding element 25 of one elastic arm 18 in a direction perpendicular to the axis XX of the spring bracket 10, without aligning with those lines VV passing through the corresponding protruding elements 25 on the opposing elastic arms 18. When the helical spring C is held within the spring bracket 10, this helps to securely hold the helical spring C with minimal axial movement and / or axial alignment by means of the staggered opposing protruding elements 25 along the helical coil of the helical spring C. This arrangement may optionally be applied to embodiments of the invention that include two or more elastic arms 18.

[0144] exist Figure 13 In one embodiment, the head 23 of one elastic arm 18 is aligned with the corresponding head 23 of the opposing elastic arm 18 in the axial direction of the spring bracket 10. For example... Figure 12 As shown, this is indicated by reference line WW, which extends in a direction perpendicular to the axis XX of the spring bracket 10 through the head 23 of an elastic arm 18 and through the corresponding head 23 on the opposite elastic arm 18, having the same advantages as described above.

[0145] exist Figure 13 The implementation plan is as described above. Figure 12 The plurality of protruding elements 25 on each elastic arm 18 gradually increase in size toward the free end 22 of each elastic arm 18. This is in Figure 13 The image is shown by a line L3 aligned with the innermost portion of each protruding element 25, which is angled inward toward the central axis XX in the direction toward the free end 22 of the elastic arm 18. This provides the aforementioned reference. Figure 12 The same advantages described.

[0146] Figure 14 This is a schematic diagram of the configuration of the elastic arm 18 in another embodiment, and is similar to... Figure 12 and Figure 13 A schematic diagram. Figure 14 The difference in this implementation is that the plurality of protruding elements 25 on each elastic arm 18 have the same dimensions. That is, each protruding element 25 protrudes inward by the same distance toward the central axis XX of the spring bracket 10. This is shown by line L4 aligned with the innermost portion of each protruding element 25, which is parallel to the central axis XX of the spring bracket 10. This helps to securely hold the coil spring C within the spring bracket 10, because in the relaxed position of the elastic arm 18, each protruding element 25 protrudes equally to engage and secure the coil spring C within the spring bracket 10.

[0147] Figures 15A to 15C This is an enlarged schematic diagram of the elastic arm 18 of the spring bracket 10 of an embodiment of the present invention, showing different configurations of the protruding element 25 intended to fall within the scope of the present invention and optionally applicable to all embodiments described herein. Figure 15A The protruding element 25 is shown, which includes a generally circular shape and curved edges where the protruding element 25 extends from the resilient arm 18 and in the innermost axial region of the protruding element 25. This configuration facilitates the insertion of the coil spring C into the spring holder 10, for example, allowing the coil spring C to cross the protruding element if it contacts the protruding element 25 during insertion when the resilient arm 18 is deflected outward, thus allowing the coil spring C to move to the fully inserted position.

[0148] Figure 15B The protruding element 25 is provided with a surface 25A that extends substantially perpendicular to the axis XX of the elastic arm 18 and the spring bracket 10. Within the scope of the invention, this surface 25A may be positioned facing either the first end 14 or the second end 16 of the spring bracket 10. Furthermore, within the scope of the invention, the protruding element 25 may be configured with two such surfaces 25A, both extending substantially perpendicular to the axis XX of the elastic arm 18 and the spring bracket 10, one surface 25A facing the first end 14 of the spring bracket 10, and a second such surface 25A facing the second end 16 of the spring bracket. This configuration facilitates the retention of the helical spring C in the desired axial position within the spring bracket 10, as the axial movement of the helical spring C will be more significantly restricted due to the perpendicular shape of the surface 25A.

[0149] Figure 15C A protruding element 25 is shown, which includes a generally angled shape, with its straight edge intersecting the angle at which the protruding element 25 extends from the resilient arm 18 and the innermost axial region of the protruding element 25. This configuration can facilitate engagement of the coil spring C within the spring holder 10, for example, by allowing the pointed edge of the protruding element 25 to more easily lie between the coils of the coil spring C when the resilient arms 18 are released by the actuator to return to their relaxed position.

[0150] Figure 16 Another embodiment of the spring bracket 10 of the invention is shown, and similar features retain the same reference numerals, and their detailed description is not repeated. Similar to the embodiments of Figures 7A to 10B, the first opening 16 at the first end 14 includes a tapered region 16A having the advantages described above. Figure 16The difference in the implementation is that the window or cutout area 60 is provided in the side wall 12 of the hollow body 11 and extends through the side wall. This allows the interior of the hollow body 11 to be observed from the outside of the spring bracket 10. In particular, this allows it to be seen when the helical spring C is received within the spring bracket 10. This can be advantageous for the use of the spring bracket 10 during the manufacturing process. For example, during quality control or performance monitoring, the presence of the helical spring C within the spring bracket 10 can be checked for each device being produced. For example, an optical sensor or camera can check for the presence of the helical spring C within the spring bracket 10, and this check can be performed using the window 60. For example, if it is detected that the spring bracket 10 is missing the helical spring C due to an insertion failure elsewhere in the manufacturing process, the device being produced may not function properly and can therefore be automatically rejected from the production line. One window 60 can be provided, or multiple windows can be provided and can be positioned at any suitable location on the side wall 12 of the spring bracket 10. The window 60 also means a reduction in the material required to manufacture each spring bracket 10, which can reduce manufacturing costs and / or also reduce the weight of the spring bracket, which may be beneficial in the manufacturing process of devices using spring brackets.

[0151] Figure 17A to Figure 17E A spring bracket 10 according to another embodiment of the invention is shown, and similar features retain the same reference numerals, and their detailed description is not repeated. (See Figures 7A to 10B) Figure 16 Similar to the embodiment described above, the first opening 16 at the first end 14 includes a tapered region 16A with the aforementioned advantages. The spring bracket 10 also includes a tapered region 17A in a second opening 17 located at the second end 15. This further facilitates insertion and alignment of the actuator 30 in the second opening 17 during use. As can be seen from FIG. 17C, the tapered region 16A of the first opening 16 extends at an angle θ4 relative to the axis XX of the spring bracket 10. The angle θ4 can vary within the scope of the invention, but can be between 10 and 40 degrees, between 15 and 35 degrees, and around 24 degrees. Furthermore, as can be seen from FIG. 17C, the tapered region 17A of the second opening 17 extends at an angle θ5 relative to the axis XX of the spring bracket 10. The angle θ5 can vary within the scope of the invention, but can be between 3 and 20 degrees, between 5 and 15 degrees, and around 10 degrees.

[0152] Within the scope of the invention, and in any of the embodiments described herein, one or both of the first opening 16 at the first end 14 and the second opening 17 at the second end 15 are intended to include such tapered regions 16A, 17A for the aforementioned advantages and having any of the aforementioned dimensions.

[0153] The implementation schemes shown in Figures 17A to 17C are similar to those shown in Figures 17A to 17C. Figure 16 Another difference in the implementation is that, although the window 60 is provided, it is located in the resilient arm 18, rather than in the side wall 12 of the hollow body 11. The window 60 still provides the aforementioned advantage of being able to detect the presence of the helical spring C within the spring bracket 10. However, compared to not having the window 60 in the resilient arm 18, the window 60 also allows the resilient arm 18 to be lighter and / or easier to deflect. This may require a smaller actuator force to deflect the resilient arm 18 by the amount needed when using the spring bracket 10. This reduced force can reduce stress on the material of the spring bracket 10 and allow the spring bracket 10 to have a longer lifespan before failure or the need for replacement.

[0154] Figure 17A to Figure 17D Another feature of the embodiment is that a recovery surface 64 is disposed on the outer region of the elastic arm 18. The recovery surface 64 is an angled surface that is radially inward toward the central axis XX of the hollow body 11 in the direction toward the second distal end 15. The recovery surface 64 helps the elastic arm 18 to fully return to a first unbiased position, in which the elastic arm 18 is flush with the outer surface of the hollow body 11 of the spring bracket 10, as shown below. Figure 17D and Figure 17E More detailed description.

[0155] Figure 17D An enlarged view of the second distal end 15 of the spring bracket 10 shown in Figure 17C is displayed. However, in Figure 17D In the diagram, the elastic arm 18 is shown slightly outward from the first unbiased position, and therefore not flush with the outer surface of the hollow body 11 of the spring bracket 10. Repeated use of the spring bracket 10 and repeated deflection of the elastic arm 18 may cause material fatigue in the elastic arm 18. This may result in the elastic arm 18 not fully returning to the desired first unbiased position when the actuator 30 is removed. Consequently, this may cause the helical spring C within the spring bracket 10 to not be held securely as required. To overcome this, it may be desirable to actively return the elastic arm to the correct first unbiased position. This can be achieved by applying a radially inward external force to the elastic arm 18. Figure 17D and Figure 17E As shown, this force can be applied, for example, by the recovery tool 65. The recovery tool 65 can slide on the second distal end 15 of the spring bracket 10 to engage the recovery surface 64 and push the elastic arm 18 radially inward to a first unbiased position, as shown. Figure 17E As shown.

[0156] As shown in Figure 17C, when the elastic arm 18 is in the correct first unbiased position, the recovery surface 64 can be set at an angle θ7 relative to the central axis XX. This helps the elastic arm 18 gradually engage the recovery tool 65 as it slides on the spring bracket 10, returning the elastic arm 18 to the correct first unbiased position. This angle θ7 can vary within the range of this disclosure and can be between 2 and 10 degrees, between 4 and 8 degrees, and around 6 degrees.

[0157] As the recovery tool 65 slides on the second distal end 15 of the spring bracket 10, the recovery tool 65 may be provided with a central hole 66 to receive the spring bracket 10. The diameter of the central hole 66 may be slightly larger than the outer diameter of the hollow body 11 of the spring bracket 10. The recovery tool may have an angled contact surface 67 configured to engage the recovery surface 64 of the resilient arm 18. The angled contact surface 67 of the recovery tool 65 may extend relative to the central axis of the recovery tool 65 at an angle θ7 that is the same angle at which the recovery surface 64 extends relative to the central axis XX of the spring bracket 10. The features of the recovery surface 64 on the resilient arm 18 should be optionally adaptable to and provided for any embodiment of the invention described herein. Furthermore, the recovery surface 64 may be engaged by means other than the recovery tool 65 described above in order to restore the resilient arm 18 to the desired first unbiased position while providing the aforementioned benefits.

[0158] Figure 18 Another embodiment of the spring bracket 10 is shown, similar to the embodiments of Figures 17A to 17C, and similar features retain the same reference numerals, and their detailed description is not repeated. As with the embodiments of Figures 7A to 10B, the first opening 16 at the first end 14 includes a tapered region 16A with the aforementioned advantages. Figure 18 The difference in the implementation is that flange 28 includes orientation feature 61. In the exemplary embodiment shown, orientation feature 61 includes a pair of radial grooves formed on the surface of flange 28 facing the first end 14. This orientation feature 61 can facilitate the correct rotational positioning of spring bracket 10 about its central axis XX, which may benefit the function of the spring bracket in use, such as for the insertion or removal of helical spring C, and / or the insertion of actuator 30. Furthermore, this orientation feature can be used in conjunction with window 60 during manufacturing. For example, an optical sensor or camera for detecting the presence of helical spring C within spring bracket 10 may be located at some point on the manufacturing equipment / system or assembly line, thus requiring the correct orientation of spring bracket 10 to align window 60 with the optical sensor or camera. Orientation feature 61 can cooperate with a corresponding feature (not shown), such as a protrusion that can be received in the groove of orientation feature 61, to ensure the correct positioning of spring bracket 10 in use.

[0159] Figure 19A to Figure 20B It shows the relationship with Figure 21A and Figure 21B The spring bracket 10 of another embodiment of the invention is used in conjunction with the actuator of another embodiment of the invention shown. Similar features retain the same reference numerals and their detailed descriptions are not repeated. FIG19A shows the arrangement of the spring bracket 10 and actuator 30 in operation steps corresponding to FIG5D and FIG7A of the foregoing embodiments, i.e., the helical spring C has been inserted into the cavity 13 of the hollow body 11, and the actuator 30 is still in the loaded position with the elastic arm 18 radially outwardly deflected. FIG19B shows an enlarged view of a portion of FIG19A, which more clearly shows the head 23 and abutment step 34 of the elastic arm 18, and the actuator 30 having its chamfered surface 33.

[0160] Similar to the embodiments described above in Figures 5D and 7A, in the stages shown in Figures 19A and 19B, the actuator 30 has deflected the elastic arm 18 outward, causing the protruding element 25 to move away from the coil spring C, and the coil spring C can fall into the spring bracket 10. Likewise, as shown in Figure 19A, line L2 extends parallel to the central axis XX of the hollow body 11 and intersects the radially innermost portion of the protruding element 25, which is located radially outside the radially outermost portion of the coil spring C. Furthermore, the head 23 and the abutting step 34 extend radially inward further than the radially innermost portion of the corresponding protruding element 25, as shown by line L1, which extends parallel to the central axis XX of the hollow body 11 and intersects the radially innermost portion of the head 23 / abutting step 34 located radially inside line L2.

[0161] However, in Figure 19A to Figure 20B In the implementation scheme, line L1 is also set to be approximately flush with the outermost radial portion of the helical spring C, and when the helical spring C is inserted into the spring bracket 10, the end of the helical spring C abuts against the chamfered surface 33 of the actuator 30, and is also substantially axially flush with the abutment step 34 of the head 23.

[0162] Figure 19A to Figure 20B The implementation scheme also differs in that the actuator 30 includes a narrowed section 62 at its distal end extending beyond the chamfered surface 33. (See Figures 19A to 19B). Figure 20BAs shown, the narrowing section 62 is configured to engage within the coil spring C. When the actuator is initially inserted into the second end 15 of the spring bracket 10, the narrowing section 62 also allows the elastic arm 18 to deflect smoothly and gradually. Therefore, during insertion of the coil spring C, the coil spring C slides within the cavity 13 and onto the narrowing section 62 of the actuator 30 until it abuts against the chamfered surface 33 of the actuator 30. At this point, the coil spring C can also abut against the edge of the abutment surface 34. Also at this point, the lowermost end of the coil spring is substantially flush with the abutment step 34 of the head 23 in the axial direction, as shown in Figure 19B. Thereafter, as previously described and as shown in Figure 20A and... Figure 20B As shown, the actuator 30 retracts from the spring bracket 10, allowing the elastic arms 18 to return to their relaxed position, and the abutment surface 34 slides inward and is located below the end of the coil spring C to support the coil spring C, while the protruding element 25 securely holds the coil spring C within the spring bracket 10.

[0163] During the insertion of the helical spring C, the narrowing section 62 received within the helical spring C helps to axially align the helical spring C within the spring holder 10. This allows the helical spring C to be held more securely within the spring holder 10 by the protruding element 25 and also ensures that the helical spring C is aligned for precise removal later in the device manufacturing process. It should be understood that during the removal of the helical spring C, the actuator 30 will be inserted into the second opening 17 at the second end 15, and the narrowing section 62 of the actuator 30 will be received within the helical spring C. This further aids in the axial alignment of the helical spring C for precise removal from the spring holder 10.

[0164] From Figure 19A to Figure 20B As can be seen, the embodiments of these figures include many of the features previously described and the technical advantages of each of the previously described features. These features include the tapered regions 16A, 17A of the first and second openings 16, 17. Furthermore, it can be seen that the resilient arm 18 includes a window 60. In the deflected position, the resilient arm 18 extends at an angle θ3 relative to the axis XX of the spring bracket 10. Such an angle θ3 can be within the range described above, and can be between 4 and 12 degrees, between 6 and 10 degrees, and approximately 8 degrees. Figure 19B also shows the maximum lateral outward deflection distance d1 of the resilient arm 18 in the deflected position relative to the outer surface of the sidewall 12 of the hollow body 11. This deflection distance d1 can have the range described above.

[0165] Within the scope of this invention and / or in any embodiment of the invention described herein, the angle θ3 of the resilient arm 18 in the deflected position relative to the axis XX, and the maximum lateral outward deflection distance d1 of the resilient arm 18 in the deflected position relative to the outer surface of the sidewall 12 of the hollow body 11, can differ between the configuration during insertion of the helical spring C and the configuration during removal of the helical spring C. For example, during insertion, the actuator 30 can engage with the spring holder 10 such that the angle θ3 and distance d1 are smaller than those during removal. This can be achieved by inserting the actuator 30 deeper into the second end 15 of the spring holder 10 during removal than during insertion. This helps ensure reliable removal of the helical spring C from the spring holder 10 by further deflection of the resilient arm during removal of the helical spring C.

[0166] In some embodiments, during the insertion of the helical spring C, such an angle θ3 can be between 4 and 12 degrees, between 6 and 10 degrees, and approximately 8 degrees. In some embodiments, during the removal of the helical spring C, such an angle θ3 can be between 7 and 15 degrees, between 9 and 13 degrees, and approximately 11 degrees. In some embodiments, during the insertion of the helical spring C, such a deflection distance d1 of the elastic arm 18 can be between 1 mm and 4 mm, between 1 mm and 3 mm, between 1 and 2 mm, and approximately 1.3 mm. In some embodiments, during the removal of the helical spring C, such a deflection distance d1 of the elastic arm 18 can be between 1 mm and 4 mm, between 1 mm and 3 mm, between 1 and 2.5 mm, and approximately 1.8 mm.

[0167] Figure 21A and Figure 21B The actuator 30 is shown, particularly the end details of the actuator 30. The actuator 30 includes the aforementioned features, including a distal end 31, a chamfered surface 33, and a narrowing section 62. The angle θ2 of the chamfered section relative to the central axis YY of the actuator 30 can be within the previously described angle range, i.e., between 10 and 50 degrees, between 15 and 45 degrees, between 20 and 40 degrees, between 25 and 35 degrees, and around 30 degrees.

[0168] The narrowing section 62 may include an outer wall extending substantially parallel to the central axis YY of the actuator 30. Alternatively, the outer wall may extend at an angle θ6 relative to the central axis YY of the actuator 30 and may be configured to taper outwards away from the distal end 31. This angle θ6 may vary within the scope of the invention and may be between 1 and 10 degrees, between 2 and 9 degrees, between 3 and 8 degrees, between 4 and 7 degrees, and around 5 or 6 degrees. During the insertion and / or removal of the helical spring C, the angled outer wall 62 of the narrowing section 62 can facilitate the insertion of the actuator into the spring holder 10 and / or the coil of the helical spring C.

[0169] The chamfered surface 33 can extend between the narrowing section 62 and the wider portion of the actuator. The wider portion can have a diameter between 7 and 13 mm. And it can be between 7 and 12 mm, between 9 and 11 mm, and around 10 mm. Before rounding towards the distal end 31, the narrowing section can give a minimum outer wall diameter of 3.5 to 9.5 mm. It can be between 4.5 and 8.5 mm, between 5.5 and 7.5 mm, or around 6.5 mm.

[0170] Figure 22 Another embodiment of the spring bracket 10 of the present invention is shown, and is similar to that in Figures 19A to 1995. Figure 20B The spring bracket 10 shown is oriented in the opposite direction in Figure 21. Similar features retain the same reference numerals and their detailed descriptions are not repeated. Figure 22The difference in the implementation is that the cross-sectional dimension of the opening 17 at the second end 15 of the hollow body 11 is smaller than the cross-sectional dimension of the inner cavity 13. That is, the distal portion of the second end 15 of the hollow body 11 includes at least one protrusion 63 extending inwardly around the circumference of the second end 15, and the second opening 17 is defined within the inner circumference of said protrusion 63 or each protrusion. Such a protrusion 63 may include an inwardly projecting wall or lip around the entire circumference of the second end 15, or one or more such inwardly projecting lips around a portion of the circumference of the second end 15. The protrusion may also include one or more discrete protrusions spaced apart from each other and extending inwardly from the circumference of the second end 15. This can help provide increased strength and / or rigidity to the hollow body, particularly in the region of the second end 15. This can also serve as a blocking formation and prevent the helical spring C from passing through the second end 15 of the spring holder 10 during the insertion step or, once the helical spring C is inserted into the spring holder, during subsequent transport and handling / manufacturing steps. The spring bracket in this embodiment will still function as described above, although it will be understood that the actuator 30 will need to have a reduced outer diameter to pass through the second opening 17. Furthermore, the heads 23 of the resilient arms 18 will need to extend inward toward the central axis XX, beyond the axial protrusions of the inner circumference of the lip 63, so that they can be engaged by the actuator 30 as previously described to deflect the resilient arms 18. This extended head 23 is configured as follows... Figure 22 As shown.

[0171] Figure 23 and Figure 24 A spring bracket 10 according to another embodiment of the present invention is shown, similar to that in FIG17A- Figure 17E The spring bracket, and similar features retain the same reference numerals, and their detailed descriptions are not repeated. Figure 23 and Figure 24 The difference with the spring bracket is that the inner surface of the sidewall 12 of the hollow body 11 includes a plurality of centering lugs 68 projecting inward toward the central axis XX of the hollow body 11. In the illustrated embodiment, four centering lugs 68 are provided. However, more than four or fewer may be provided, and the centering lugs 68 may optionally be spaced equally around the inner circumference of the sidewall 12.

[0172] The centering lugs 68 are formed as curved bevels, and their inward projection increases as they extend toward the second distal end 15 of the spring bracket 10. In use, the centering lugs 68 are used to contact and center the helical spring C held within the spring bracket 10, thereby accurately holding the helical spring C at its center within the spring bracket 10. The centering lugs 68 can compensate for any tolerance between the outer diameter of the helical spring C and the inner diameter of the inner cavity 13 to reduce play between the helical spring C and the spring bracket 10. This helps ensure that the helical spring C is accurately positioned during insertion into the spring bracket 10, thus helping to ensure that the helical spring C can be structurally and securely engaged. This helps to prevent the spring from being accidentally or prematurely removed during transport of the spring bracket 10 or during manufacturing processes that require accurate removal and positioning of the helical spring into the device being manufactured. This may help prevent manufacturing errors and / or downtime. The features of the centering lugs 68 can optionally be adapted and provided for any embodiment of the invention described herein.

[0173] Figures 25A to 25E A series of steps using the spring bracket 10 of the aforementioned embodiment are shown, which is used in conjunction with an alternative embodiment of the actuator 30. The actuator 30 includes a pair of movable jaws 37 movably mounted on a chuck 38, such that the jaws 37 can translate toward and away from each other. The jaws 37 can be moved from, as... Figure 25A , Figure 25B , Figure 25D and Figure 25E The disengagement position shown is moved to the position shown in the figure. Figure 25C The shown joint position.

[0174] In the disengaged position, the jaws 37 are positioned close to or in contact with each other to form a rod-like shape. In the engaged position, the jaws 37 are positioned far apart from each other in the generally radial direction of the rod-like shape.

[0175] In use, Figure 25A In the steps shown, the actuator 30 is initially spaced apart from the second distal end 15 of the spring bracket 10, and the rod-shaped actuator gripper 37 is in the disengaged position and is generally aligned with the central axis XX of the spring bracket 10.

[0176] exist Figure 25B In the steps shown, the actuator 30 moves toward the spring bracket 10 in the direction indicated by arrow H, and the gripper 37 is inserted into the second opening 17 at the second distal end 15 of the spring bracket 10. The actuator 30 is inserted such that the distal end of the gripper 37 is generally aligned in the axial direction of the spring bracket 10, and the head 23 is located at the free end 22 of the deflectable member 18.

[0177] exist Figure 25CIn the next step shown, the grippers 37 are moved separately to the engagement position as indicated by arrow I, such that they engage the corresponding adjacent deflectable members 18. This causes the deflectable members 18 to move from a first unbiased position to a second biased position in the direction indicated by arrow J. This also causes the protruding element 25 of each deflectable member 18 to move outward. At this stage, the helical spring C can be inserted into the spring bracket 10 through the first opening 16 at the first proximal end 14 of the spring bracket 10. For the purpose of illustrating other features described herein, Figures 25A to 25E The helical spring C is not shown in the diagram.

[0178] Once the helical spring C is fully inserted, making contact with or approximately near the actuator gripper 37, the gripper 37 moves back to the disengaged position in the direction indicated by arrow K. This allows the deflectable member 18 to return to the unbiased position, as indicated by arrow L. Thus, the protruding element 25 engages the helical spring C to hold it within the spring holder 10.

[0179] Finally, Figure 25E In the steps shown, the actuator retracts from the spring bracket 10 in the direction indicated by arrow M. The helical spring C (not shown) remains securely held within the spring bracket 10.

[0180] The above sequence of steps describes an exemplary helical spring insertion process using the spring holder 10 and actuator 30 of this embodiment of the invention. It should be understood that the method for removing the helical spring C from the spring holder 10 may include steps that are the reverse of the steps described above for using the spring holder 10 and actuator 30 of this embodiment of the invention.

[0181] Despite Figures 25A to 25E In the figures, the spring bracket 10 and actuator 30 are shown in a generally horizontal orientation; however, the apparatus and methods used are not limited to this orientation, and in alternative embodiments, the spring bracket 10 and actuator may operate in other orientations, including but not limited to vertical, such as in Figure 5A- Figure 6E As shown in the implementation scheme. For example, the spring bracket 10 can be vertically oriented during the insertion of the helical spring, with the first proximal end 14 at the top, and can be vertically oriented during the removal of the helical spring, with the second distal end at the top.

[0182] During the insertion and removal of the helical spring, the helical spring C can be conveyed into and out of the spring holder by various means, such as falling under its own weight, being actively driven, and by any other means mentioned above, such as under the force of an airflow from an air source.

[0183] The above reference Figures 25A to 25E The alternative configuration actuator 30 described herein may optionally be adapted to and provided for any embodiment of the spring bracket 10 of the invention described herein.

[0184] exist Figures 25A to 25E In the exemplary embodiment of the actuator 30 shown, the actuator 30 is described as including two grippers 37. However, the invention is not intended to be limited to this configuration, and in alternative embodiments, the actuator may include one gripper 37 or may include two or more grippers 37. In some cases, the actuator 30 may include the same number of grippers 37 as the number of deflectable members 18 on the spring bracket 10 with which the actuator 30 is intended to cooperate, such that one gripper 37 deflects each deflectable member 18.

[0185] exist Figures 25A to 25E In the exemplary embodiment of the actuator 30 shown, the actuator 30 is described as moving the deflectable member by contacting the distal end of each gripper 37 of the corresponding head 23. However, the invention is not intended to be limited to this configuration, and in alternative embodiments, the actuator may be arranged or operated to engage other portions of the deflectable member, rather than a specific actuating feature, such as the head 23 in this example, and / or through another region of the one or more grippers 37 instead of the distal end. Furthermore, it is contemplated that other means may be employed to achieve movement of the resilient arm during the exemplary insertion / removal process besides the exemplary embodiment of the actuator 30 shown and described. Several other external manipulators or mechanisms (not shown) may engage and move the one or more deflectable members as needed. Such embodiments may similarly not require engagement with a specific actuating feature, or may use the specific actuator 30 shown and described, but these are not excluded from the scope of this disclosure.

[0186] As described above, throughout this disclosure, the terms "inward" and "outward" will be understood to be used generally relative to the body of the spring bracket 10. For example, relative to the central axis XX or relative to the hollow body 11 / cavity 13 of the spring bracket 10. Therefore, as used herein, a deflectable member and / or one or more retaining structures positioned in the second deflection position or extending "outward" will be understood to be positioned further away from the cavity 13 and / or axis XX than when positioned further inward in the first unbiased position. In some embodiments, as described above, the one or more retaining structures in the second bias position may be positioned outside the inner surface of the cavity 13. This helps to ensure the helical spring is discharged from the cavity 13. However, it should be understood that in alternative embodiments within the scope of the invention, in the second bias position, compared to the first unbiased position, the one or more retaining structures may be positioned further outward, rather than outside the inner surface of the cavity 13. The one or more retaining structures in the second bias position are further outward, such that providing a gap at least larger than the diameter of the helical spring to allow the helical spring to be discharged from the cavity 13 is sufficient. In one exemplary embodiment, where the diameter of the helical spring is significantly smaller than the inner diameter of the cavity (but large enough to be held by the one or more retaining structures when the one or more deflectable members are in the first unbiased position), the one or more retaining structures may not need to deflect outward on the inner surface of the cavity 13 to disengage the helical spring to allow its release.

[0187] The various embodiments of the spring bracket 10 illustrated and described above are intended to be configured in a range of shapes and sizes, as well as relative dimensions, within the scope of the invention. However, exemplary dimensions are described herein with reference to the embodiment shown in FIG17C and the dimensions marked therein.

[0188] The spring bracket 10 may include a total length d2 between 50 mm and 90 mm in the direction of axis XX, and may be between 60 mm and 80 mm, and may be around 70.5 mm or around 73.5 mm.

[0189] The flange 28 may include a height d3 between 1 mm and 5 mm in the axial direction XX, and may be between 2 mm and 4 mm, and may be around 3 mm.

[0190] The elastic arm 18 may include a total length d4 in the axial direction XX from the fixed end 21 to the free end 22, which is between 10 mm and 20 mm, and may be between 12 mm and 18 mm, and may be between 14 mm and 16 mm, and may be around 16.3 mm.

[0191] When disposed in the side wall 12, the window 60 may have a length between 5 mm and 25 mm in the direction of axis XX, and may be between 10 mm and 20 mm, and may be approximately 15 mm. When disposed in the elastic arm 18, the window 60 may have a length d5 ​​in the direction of axis XX, which is between 1.5 mm and 8 mm, and may be between 2.5 mm and 7 mm, and may be between 3.5 mm and 6 mm, and may be approximately 4.3 mm.

[0192] The hollow body 11 is shown and described as a cylindrical tube configured with a circular cross-section. This allows for close accommodation of a conventional circular helical spring C. It also facilitates the insertion of the helical spring C and the alignment of the spring bracket 10 for removal of the helical spring C, since proper positioning of the spring bracket 10 in use does not require a specific rotational orientation about the central axis XX. However, the invention is not limited to this configuration of the spring bracket; other dimensions and cross-sectional shapes are possible, such as elliptical, triangular, or square shapes, or other polygonal shapes.

[0193] The hollow body 11 is shown and described as having a substantially constant cross-section along its length from the first end 14 to the second opposite end 15. Referring to FIG17C, in such an embodiment, the inner diameter in the region of the first end 14 of the spring bracket 10 is... The inner diameter in the region that is substantially equal to the second end 15 of the spring bracket 10 This facilitates ease and cost-effectiveness in manufacturing and manipulating the spring bracket 10 during assembly or manufacturing processes. However, the invention is not intended to be limited to this configuration, and in alternative embodiments, the spring bracket 10 may vary its cross-sectional dimensions along its length. For example, the cross-section may be a circle of varying diameters along the length of the spring bracket, and / or the cross-section may be a shape other than a circle along a portion of the length of the spring bracket. For example, the inner diameter... It can be larger than the inner diameter. This makes the inner cavity slightly wider in the region of the first end 14 of the spring bracket 10, through which the coil spring C is inserted and removed. In addition to the assistance from the tapered region 16A, this also helps to accurately guide the coil spring C into the spring bracket 10. This also allows the coil spring C to be more tightly confined in the region of the second end 15 of the spring bracket 10, where it is engaged and held by the retaining structure of the protruding element 25 and the notch 26. However, within the scope of the invention, the opposite can be true, and the inner diameter... It can be smaller than the inner diameter This makes the inner cavity slightly narrower in the region of the first end 14 of the spring bracket 10.
