Description

Technical Field

[0001] This invention relates to the field of machining, and in particular to a flexible belt fixing fixture and a flexible belt fixing method. Background Technology

[0002] When sewing or bonding flexible materials, it's necessary to fix them in place to ensure the final product's shape and dimensions meet requirements, preventing them from shifting during processing. For example, when sewing watch straps, the space around the strap is limited. Furthermore, the overall aesthetic requirements for the watch necessitate precise stitch dimensions and shapes. Therefore, maintaining the strap's shape stability during sewing is crucial. Improving processing efficiency while maintaining shape stability becomes a key challenge. Summary of the Invention

[0010] Furthermore, the material trough includes a contouring groove and a band groove that are connected. The contouring groove is located at one end of the band groove, the positioning groove is located at the other end of the band groove, and the first clamping surface is higher than the bottom of the band groove.

[0011] The operation window includes a rectangular window, which is located in the slot and adjacent to the contour slot, and the length direction of the rectangular window is perpendicular to the length direction of the slot.

[0012] Furthermore, the feed trough also includes:

[0020] The platform includes a positioning part, which includes a rear seat, a top ball, and an elastic element. The rear seat has a first receiving hole.

[0021] The positioning part is disposed on the side of the positioning groove away from the second positioning surface. The top ball is retractably disposed in the first receiving hole through the elastic element. The clamping component is engaged in the positioning groove and simultaneously abuts against the first positioning surface, the second positioning surface and the top ball.

[0027] Press the first cover plate onto the connection position between the flexible strip and the connected component;

[0028] Press the second cover plate onto the flexible belt to pull the connecting section of the flexible belt back to the position corresponding to the operating window, wherein the first cover plate is located between the positioning groove and the second cover plate.

[0029] Furthermore, the second cover plate with a flexible belt pressure cap previously includes:

[0030] A flexible strip located between the clamping assembly and the first cover plate is laid along the feed trough.

[0035] This invention discloses a flexible strip fixing fixture and a flexible strip fixing method. First, a clamping assembly clamps the flexible strip at its clamping section, while simultaneously passing the connecting section of the flexible strip through the connecting hole of the connected component and folding it over. After the clamping assembly is inserted into the positioning groove, a first cover plate and a second cover plate are used sequentially to press the flexible strip together. Thus, the first and second cover plates, located on both sides of the operating window, simultaneously fix the flexible strip, preventing it from moving freely and affecting its positional accuracy. Furthermore, when the second cover plate presses onto the flexible strip, it ensures that the flexible strip is simultaneously stretched flat by the clamping assembly and the first cover plate, preventing wrinkles in the material groove and further ensuring the processing accuracy of the flexible strip.

In the detailed description of the invention below, certain specific details are described in detail. Those skilled in the art will fully understand the invention even without these details. To avoid obscuring the essence of the invention, well-known methods, processes, flows, elements, and circuits are not described in detail.

[0067] Unless the context explicitly requires it, words such as "including" or "contains" throughout the application should be interpreted as including rather than exclusive or exhaustive; that is, meaning "including but not limited to".

[0068] In the description of this invention, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0069] Figure 1 and Figure 2 This is a schematic diagram of the flexible band fixing fixture in different directions. Among them, Figure 1The flexible strip A and the connected component B are not shown in the figure, and the limiting part 45 in the figure is in a limiting state. Figure 2 The limiting part 45 in the middle is in the open state.

[0070] Figure 3 This is an exploded view of the flexible belt fixing fixture. Both the first cover plate 51 and the second cover plate 52 are open. The clamping assembly is in the state before being inserted into the positioning slot 42.

[0071] Figure 4 This is a cross-sectional schematic diagram of the flexible belt fixing fixture. A partial enlarged view is also shown in the figure. This enlarged view is in the direction indicated by arrow E in the cross-sectional view and does not show the first cover plate 51, the second cover plate 52, or the clamping assembly. The dashed lines E and F in the figure illustrate different positions of the flexible belt A on the flexible belt fixing fixture. When the flexible belt A is clamped by the clamping assembly and the first cover plate 51, its two ends are relatively fixed. In this state, the flexible belt A is taut, approximately taut, or suspended above the material groove 41, as shown by the dashed line F. When the second cover plate 52 is pressed down, the flexible belt A1 will exhibit the state shown by the dashed line G, with its left side adhering to the bottom of the material groove 41, while its right side will tilt towards the clamping assembly.

[0072] Figure 5 This is a schematic diagram of the clamping assembly. The clamping assembly in the diagram is in a clamping state, and its overall shape is roughly block-like. Figure 6 This is an exploded view of the clamping assembly. Figures 5-6 As shown, the clamping assembly consists of a pressing part 1, a locking part 2, and a bearing part 3.

[0073] Figure 7 and Figure 8 The clamping components are in different working states. Among them, Figure 3 With the clamping assembly in the open state, rotating the pressing part 1 and the locking part 2 in the directions indicated by arrows D and C in the figure respectively will lock the clamping assembly onto the flexible strip A. That is, it presents as... Figure 4 The state shown in the image.

[0074] Figure 9 This is a schematic diagram of the flexible belt fixing fixture's workflow. State I, State II, and State III in the diagram correspond to different stages in which the flexible belt A is fixed by the fixture. In State I, the arrow indicates the direction in which the connected component B is fitted onto the flexible belt A through the connecting hole B1.

[0075] Optionally, the aforementioned connected component B can be used to connect the flexible band A to devices such as the watch body, wristband body, or helmet body, thereby allowing the flexible band A to be used to bind the aforementioned devices to the human body. In the following explanation, the flexible band A is used as a watch band, and the connected component B is used as a lug.

[0076] In some implementations, such as Figures 1-9 As shown, the flexible band fixing fixture of this embodiment includes a platform 4, a clamping assembly, a first cover plate 51, and a second cover plate 52. The platform 4 is provided with a material groove 41 and a positioning groove 42. An operation window 411 is opened on the bottom surface of the material groove 41, extending through the material groove 41. The positioning groove 42 is located in the horizontal extension direction of the material groove 41. The clamping assembly has opposing first clamping surfaces 31 and 11, and is detachably mounted on the positioning groove 42. The first cover plate 51 and the second cover plate 52 are movably connected to the platform 4 and located on both sides of the operation window 411. The second cover plate 52 is located between the positioning groove 42 and the first cover plate 51.

[0077] Simultaneously, the flexible belt fixing fixture is configured to have a pre-installed state and a positioning state. In the pre-installed state, the clamping section A2 of the flexible belt A is fixed to the clamping assembly, and the first cover plate 51 presses against the connection position between the flexible belt A and the connected component B. The connecting section A1 of the flexible belt A passes through the connecting hole B1 of the connected component B and folds over to extend towards the clamping section A2. In the positioning state, the second cover plate 52 presses against the flexible belt A to pull the connecting section A1 of the flexible belt A back to the position corresponding to the operating window 411.

[0078] The flexible strip fixing fixture of this embodiment allows the first cover plate 51 and the second cover plate 52 to be independently pressed onto the flexible strip A, thereby positioning the relative positional relationship between the flexible strip A and the connected component B. This facilitates the fixing of the connecting segment A1 of the flexible strip A and the connection between the connecting segment A1 and the connected component B. The fixing method of the connecting segment A1 includes, but is not limited to, sewing, bonding, or anchoring. The following description uses sewing as an example.

[0079] In this embodiment, the connecting segment A1 of the flexible strip A is located in a certain section of the flexible strip A. When connecting the flexible strip A to the connected component B, the connecting segment A1 is bent to fix it to the connected component B. Figure 9 In state I, the connecting segment A1 is located at one end of the flexible strip A. In this state, the connecting segment A1 is straight. When the flexible strip A is placed on the flexible strip fixing fixture, the connecting segment A1 will be bent in the opposite direction, so that it wraps around the side of the lug (e.g., Figure 9 (As shown in state II).

[0080] It's easy to understand that the flexibility of the flexible band A allows the watch strap to fit snugly against the wrist when worn. However, during sewing, the needle bar of the sewing machine causes the connecting section A1 of the flexible band A to deform as it pierces the fabric. This process results in uneven stitches, leading to crooked or unequal stitches. A stitch is a unit formed by one or more threads, which connect, interweave, or intertwine with the fabric each time the sewing machine needle pierces it. During sewing, the needle bar mechanism, thread hook mechanism, and thread take-up mechanism are located above and below the operating window 411, respectively, and the connecting section A1 is sewn together by the up-and-down movement of the needle bar relative to the operating window 411.

[0081] Specifically, in this embodiment, when the flexible band A is simultaneously fixed by the clamping component and the first cover plate 51, the flexible band A will exhibit an inclined state in the area between the clamping component and the first cover plate 51 (e.g., Figure 9 Medium state III and Figure 4 (As shown by the dashed line F), this is the pre-installed state. In other words, it extends from the bottom of the material groove 415 towards the second clamping surface 11. At this time, the flexible strip A cannot be completely attached to the bottom of the material groove 41.

[0082] In this configuration, as the second cover plate 52 is pressed down, the flexible belt A gradually comes into contact with the bottom of the trough 41 as the second cover plate 52 adheres to the top of the flexible belt A. Simultaneously, the length of the flexible belt A between the clamping assembly and the first cover plate 51 changes, thus continuously pulling the flexible belt A from the top of the connected component B to the bottom of the connected component B until the second cover plate 52 completely covers the platform 4. Figure 9 In states III and II, the connecting segment A1′ shown by the dashed line is the position before the second cover plate 52 presses down. As the second cover plate 52 presses down, the connecting segment A1′ moves towards the first cover plate 51 (as shown by the arrow in state III), which is the positioning state. Ultimately, this ensures that the first cover plate 51 and the second cover plate 52 press down on both sides of the sewing area of ​​the flexible tape A. At the same time, the flexible tape A in the sewing area is in a flattened state. Therefore, when the needle bar of the sewing machine drives the thread to pierce the flexible tape A, the flexible tape will not move randomly.

[0083] Preferably, the clamping force of the first cover plate 51 pressing against the connecting section A1 is configured to be less than the clamping force applied by the clamping assembly to the clamping section A2. When the second cover plate 52 is pressed down, the flexible band A can slide relative to the first cover plate 51 while remaining stationary relative to the clamping assembly. This ensures that the connecting section A1 can move to the corresponding position of the operating window 411.

[0084] In summary, the flexible belt fixing fixture of this embodiment of the invention first uses a clamping assembly to clamp the clamping section A2 of the flexible belt A, while simultaneously folding the connecting section A1 of the flexible belt A through the connecting hole B1 of the connected component B. After the clamping assembly is inserted into the positioning groove 42, the first cover plate 51 and the second cover plate 52 are used to press the flexible belt A together in sequence. Thus, the first cover plate 51 and the second cover plate 52 located on both sides of the operating window 411 simultaneously fix the flexible belt A, preventing the flexible belt A from moving randomly during the processing of the connecting section A1, which would affect the processing accuracy of the flexible belt A. Furthermore, when the second cover plate 52 is pressed onto the flexible belt A, it ensures that the flexible belt A can be stretched flat by both the clamping assembly and the first cover plate 51, preventing the flexible belt A from wrinkling in the material groove 41, further ensuring the processing accuracy of the flexible belt A. And it ensures that the processed flexible belt A is stably connected to the connected component B.

[0085] Preferably, the first cover plate 51 and the second cover plate 52 are rotatably connected to the platform 4. Simultaneously, a limiting part 45 is provided near the material trough 41. The limiting member 451 of the limiting part 45 is rotatably connected to the platform 4. When the first cover plate 51 and the second cover plate 52 are in the pressed position, the limiting member 45 rotates to the top edge of the first cover plate 51 and the second cover plate 52, thereby locking the position of the two cover plates.

[0086] In some implementations, such as Figures 1-9 As shown, the material trough 41 includes a connected contour groove 412 and a band groove 413. The contour groove 412 is located at one end of the band groove 413, and the positioning groove 42 is located at the other end of the band groove 413. The aforementioned first clamping surface 31 is higher than the bottom of the band groove 413. The operation window 411 includes a rectangular window, which is located in the band groove 413 and adjacent to the contour groove 412. The length direction of the rectangular window is perpendicular to the length direction of the band groove 413.

[0087] In this embodiment, the contour groove 412 is related to the shape of the connected component B. Figure 2 The image shows a specific form of a contoured groove 412, which prevents the lug from moving towards the positioning groove 42 when it is placed inside. Conversely, a band groove 413 is used to accommodate the flexible band A. Therefore, its width needs to be adapted to the width of the flexible band A.

[0088] Furthermore, to better adapt the platform 4 to the sewing machine, the bottom surface of the platform 4 is made flat, and the thickness of the platform 4 is controlled within a certain range so that the flexible strip A can be precisely positioned within the groove 413, and the needle bar can easily perform up-and-down piercing movements along the height of the platform 4. Therefore, after the clamping assembly is installed in the platform 4, the first clamping surface 31 will be higher than the bottom of the material groove 41. This embodiment utilizes the height difference between the first clamping surface 31 and the bottom of the groove 413, so that during the switch from the pre-installed state to the positioning state, the length of the flexible strip A between the first cover plate 51 and the clamping assembly needs to be increased to tighten the flexible strip A.

[0089] In some implementations, such as Figures 1-9 As shown, the material trough 41 also includes two clearance windows 414, and the rectangular window is located between the two clearance windows 414 along the length of the rectangular window.

[0090] It's easy to understand that during the sewing process, the sewing machine uses its presser foot to press against the seam of the flexible tape A (e.g., ...). Figure 9 (As shown in the dashed box H), to prevent the connecting section A1 from lifting during sewing. During this process, the presser foot will move along the width direction of the flexible strip A. Under this premise, two clearance surfaces 521 are provided at both ends of the operation window 411 to allow the presser foot to move freely.

[0091] In some implementations, such as Figures 1-9 As shown, the platform 4 includes two supporting frames 43, which are located between the operating window 411 and the clearance window 414, respectively. The first cover plate 51 includes a first claw 511 and a second claw 512, which extend towards the second cover plate 52 and correspond to the two supporting frames 43. The two claws can press against both sides of the seam, ensuring that the flexible strip A does not move arbitrarily. At the same time, when the first claw 511 and the second claw 512 apply a pressing force to the flexible strip A and the connected part B, the two supporting frames 43 can support the connecting section A1, preventing the connecting section A1 from being recessed into the operating window 411 due to the pressure of the first cover plate 51 and the puncture of the needle bar.

[0092] In some implementations, such as Figures 1-9 As shown, the first cover plate 51 has a contoured surface 513, which conforms to the top surface shape of the connected component B. The first cover plate 51 simultaneously presses against the flexible strip A and the connecting segment A1; therefore, the contoured surface 513 allows the first cover plate 51 to fit the top of the connecting segment A1. This avoids excessive pressure applied by the first cover plate 51 to the flexible strip A, preventing the flexible strip A from sliding relative to the first cover plate 51, or insufficient pressure, which would prevent the flexible strip A from being taut in the pre-assembled state.

[0093] In some implementations, such as Figures 1-9As shown, the second cover plate 52 has a clearance surface 521. When the second cover plate 52 is in the pressing position, the clearance surface 521 extends from the bottom of the second cover plate 52 to the first clamping surface 31. This clearance surface 521 allows the flexible strip A to extend from the bottom of the material groove 41 to the clamping assembly, avoiding damage to the flexible strip A caused by the second cover plate 52 during the pressing process.

[0094] In some implementations, such as Figures 1-9 As shown, the positioning groove 42 laterally includes two first positioning surfaces 421 and two second positioning surfaces 422. The two first positioning surfaces 421 and the two second positioning surfaces 422 are respectively located on both sides of the groove. The first positioning surfaces 421 are arranged along the extension direction of the groove, and the second positioning surfaces 422 are perpendicular to the extension direction of the groove 41 and located on the side of the positioning groove 42 near the first cover plate 51. The platform 4 includes a positioning part 44, which includes a rear seat 441, a top ball 442, and an elastic member 443. The rear seat 441 has a first receiving hole 444. The positioning part 44 is disposed on the side of the positioning groove 42 away from the second positioning surfaces 422. The top ball 442 is telescopically disposed in the first receiving hole 444 through the elastic member 443. The clamping assembly is engaged in the positioning groove 42 and simultaneously abuts against the first positioning surfaces 421, the second positioning surfaces 422, and the top ball 442.

[0095] The positioning part 44 allows the clamping assembly to abut against the side of the positioning groove 42 near the first cover plate 51. When the clamping assembly is clamped at the predetermined position of the flexible belt A and the flexible belt fixing fixture is in the positioning state, it can be ensured that the connecting section A1 moves to the position of the operation window 411.

[0096] Figure 10 This is a flowchart illustrating the flexible strip fixing method. Figures 1-10 As shown, the flexible belt fixing fixture in the above embodiments can be operated in the following manner.

[0097] Step S100: Fix the flexible band A to the clamping assembly, wherein the clamping assembly has a first clamping surface 31 and a second clamping surface 11 opposite to each other.

[0098] Specifically, the clamping assembly includes a supporting part 3, a pressing part 1, and a locking part 2. The supporting part 3 includes the aforementioned first clamping surface 31. The pressing part 1 is rotatably connected to the supporting part 2, and the rotation axis of the pressing part 1 is parallel to the first clamping surface 31. The pressing part 1 includes the aforementioned second clamping surface 11 opposite to the first clamping surface 31. The locking part 2 is rotatably connected to the supporting part 3, and the rotation axis of the locking part 2 is perpendicular to the first clamping surface 31. When the pressing part 1 is in the pressing position, the locking part 2 is engaged at the top and / or side of the pressing part 1. Simultaneously, the clamping assembly is detachably installed in the positioning groove 42, and the first clamping surface 11 is flush with the bottom of the material groove 42.

[0099] In this embodiment, the rotation directions of the pressing part 1 and the locking part 2 are configured such that their rotation planes are perpendicular to each other. When the pressing part 1 rotates from above the first clamping surface 31, it can press against the flexible strip A. In this state, another clamping area is formed between the first clamping surface 31 and the second clamping surface 11. The cross-section of this clamping area can be adapted to the shape of the flexible strip A. For example, the cross-sectional shape can be rectangular. After the locking part 2 rotates from the side of the first clamping surface 31, it can limit the pressing part 1 by contacting the top or side area of ​​the pressing part 1.

[0100] Optionally, the pressing part 1 includes a body 1b and a pad 1a. The pad 1a is detachably fixed to the body 1, and the side of the pad 1a facing the first clamping surface 31 is used to form the second clamping surface 11. The pad 1a can be made of rubber. By pressing the pad 1a onto the flexible belt A, the flexible belt A can be protected from excessive compression, and the friction generated by its own elastic deformation can limit its movement on the clamping assembly.

[0101] Preferably, a rectangular groove is provided at the top of the bearing portion 3, and the bottom of the rectangular groove is the aforementioned first clamping surface 31. When the pressing portion 1 is in the pressing position, the pad 1a and the rectangular groove form a clamping area. Conversely, Figure 7 The flexible strip A shown in the diagram also has a roughly rectangular cross-section along its extension direction, but its thickness is greater than or slightly greater than the distance between the first clamping surface 31 and the second clamping surface 11 when the clamping assembly is in the locked state. This ensures that the pressing part 1 and the bearing part 3 can apply clamping force to the flexible strip A. The width of the strip structure is adapted to the width of the rectangular groove to ensure that the flexible material does not wrinkle or warp within the rectangular groove.

[0102] In some implementations, such as Figures 1-10 As shown, the pressing part 1 also includes a first U-shaped groove 12, which faces the side of the pressing part 1. The locking part 2 includes a swing arm 21, which is rotatably engaged in the first U-shaped groove 12.

[0103] Specifically, when the pressing part 1 is in the pressing state, the inner wall of the first U-shaped groove 12 extends horizontally. This allows the swing arm 21 to slide into the first U-shaped groove 12 by horizontal swinging. As a result, the structure of the clamping assembly is more compact.

[0104] In some implementations, such as Figures 1-10As shown, the swing arm 21 has a second U-shaped groove 211 corresponding to the first U-shaped groove 12, and the opening of the second U-shaped groove 211 is offset from the opening of the first U-shaped groove 12. In this embodiment, the second U-shaped groove 211 is further formed on the swing arm 21, and the inner wall of the second U-shaped groove 211 extends through the swing arm 21 from top to bottom, so that the first U-shaped groove 12 and the second U-shaped groove 211 can engage with each other. This increases the swing amplitude of the swing arm 21 when locked, allowing it to rotate more towards the bearing part 3, thereby making the overall structure of the clamping assembly in the locked state more compact, so as to facilitate its installation in the positioning groove 42 of the platform 4.

[0105] In some implementations, such as Figures 1-10 As shown, the pressing part 1 also includes a first connecting side 13 and a swing side 14 that are far apart from each other, and the first U-shaped groove 12 is located on the swing side 14. The swing arm 21 has a connecting end 212 and an operating end 213. The bearing part 3 includes a second connecting side 32 and a third connecting side 33 that are far apart from each other, the second connecting side 32 is hinged to the first connecting side 13, and the connecting end 212 is hinged to the third connecting side 33.

[0106] Specifically, the pressing part 1 further includes a first rotating shaft 1c, and the locking part 2 further includes a second rotating shaft 22. The first rotating shaft 1c and the second rotating shaft 22 are respectively used to realize the rotational connection between the pressing part 1 and the locking part 2 and the bearing part 3.

[0107] By fixing the pressing part 1 and the supporting part 3, as well as the supporting part 3 and the locking part 2, at a position away from the first rotating shaft 1c, a clamping force can be applied to the flexible strip A relatively easily. At the same time, this area can be offset from the extension direction of the flexible strip A to avoid interference when the flexible strip A is locked with the clamping assembly.

[0108] In some implementations, such as Figures 1-10 As shown, the pressing part 1 includes a hook 15, which is bent to form a first U-shaped groove 12. That is, in this embodiment, the first U-shaped groove 12 is located inside the hook 15. The supporting part 3 includes a first clearance groove 34 and a second clearance groove 35 located on the third connecting side 33, and the first clearance groove 34 and the second clearance groove 35 intersect. When the pressing part 1 is in the pressing position, the hook 15 is located in the first clearance groove 34 and the first U-shaped groove 12 is aligned with the second clearance groove 35. When the locking part 2 is in the locking position, the swing arm 21 is located in the second clearance groove 35.

[0109] Figure 6The figure shows a specific form of the first clearance groove 34 and the second clearance groove 35. The first clearance groove 34 penetrates the bearing portion 3 in the thickness direction, and the second clearance groove 35 penetrates the bearing portion 3 in the width direction. When the pressing portion 1 is in the pressing state, the hook 15 is completely submerged in the first clearance groove 34. When the locking portion 2 is in the locking state, the swing arm 21 can also be completely submerged in the second clearance groove 35. As a result, when the clamping assembly clamps the flexible strip A, the whole structure is block-shaped, which makes it easy to clamp it on the positioning groove 42.

[0110] In some implementations, such as Figures 1-10 As shown, the pressing part 1 also includes a positioning member 16, a second receiving hole 17, and an elastic member 18. Figure 6 (Not shown in the image), the positioning member 16 can be telescopically moved along the second receiving hole 17 via the elastic member 18. The operating end 213 includes a positioning recess 2131. When the locking part 2 is in the locked position, the elastic member 18 pushes part of the positioning member 16 from the second receiving hole 17 into the positioning recess 2131.

[0111] Specifically, the positioning element 16 is a top ball, and the elastic element 18 is a spring. Additionally, a sleeve 1d is provided on the pressing part 1, with a second receiving hole 17 formed inside the sleeve 1d. Utilizing the cooperation between the top ball and the spring in this embodiment, when the swing arm 21 swings to the locking position, the top ball precisely engages with the positioning recess 2131, ensuring that the locking part 2 is stably engaged on the pressing part 1 and preventing wobbling.

[0112] Step S200: Insert the clamping assembly into the positioning groove 42. The positioning part 44 in the above embodiment allows the clamping assembly to stably abut against the side wall of the positioning groove 42.

[0113] Step S300: Pass the connecting segment A1 of the flexible strip A through the connecting hole B1 of the connected component B and fold it over.

[0114] Step S400: Place the connector B in the feed trough 41 and pull the flexible belt A.

[0115] Specifically, the connector B is positioned within the contour groove 412. Simultaneously, this process causes the flexible belt A to move, and pulls it in the opposite direction to apply a preload. In this configuration, the first cover plate 51 can be pressed down simultaneously. This tauts the flexible belt A located between the first cover plate 51 and the clamping assembly. Figure 9 State I shows two connected components B fitted onto the flexible strip A.

[0116] The solid line indicates the relative position of the connected component B to the flexible strip A before the second cover plate 52 is pressed in place. The dashed line indicates the relative position of the connected component B to the flexible strip A after the second cover plate 52 is pressed in place.

[0117] Step S500: Press the first cover plate 51 onto the connection position between the flexible strip A and the connected component B. At this time, control the pressing force of the first cover plate 51 to avoid excessive pressing force causing damage to the flexible strip A.

[0118] Step S600: Press the second cover plate 52 onto the flexible belt A to pull the connecting section A1 of the flexible belt A back to the position corresponding to the operating window, wherein the first cover plate 41 is located between the positioning groove 42 and the second cover plate 52. Specifically, the first clamping surface 31 is higher than the bottom of the material trough 41.

[0119] In summary, the flexible strip fixing method of this embodiment of the invention first uses a clamping assembly to clamp the clamping section A2 of the flexible strip A, while simultaneously folding the connecting section A1 of the flexible strip A through the connecting hole B1 of the connected component B. After the clamping assembly is inserted into the positioning groove 42, the flexible strip A is pressed together sequentially using the first cover plate 51 and the second cover plate 52. Thus, the first cover plate 51 and the second cover plate 52 located on both sides of the operating window 411 simultaneously fix the flexible strip A, preventing the flexible strip A from moving freely during the processing of the connecting section A1, which would affect the processing accuracy of the flexible strip A. Furthermore, when the second cover plate 52 presses onto the flexible strip A, it ensures that the flexible strip A can be stretched flat by both the clamping assembly and the first cover plate 51, preventing wrinkles in the flexible strip A in the material groove 41, further ensuring the processing accuracy of the flexible strip A. This also ensures a stable connection between the processed flexible strip A and the connected component B.

[0120] In some implementations, such as Figures 1-10 As shown, the second cover plate 52 is pressed onto the flexible strip A, which includes the flexible strip being arranged along the feed groove 41 between the clamping assembly and the first cover plate 51.

[0121] The operator can use their hand strength to press the flexible strip A towards the bottom of the trough 41 before the second cover plate 52 is pressed on, so as to reduce the risk of the second cover plate 52 scratching the upper surface of the flexible strip A.

[0122] In some implementations, such as Figures 1-10 As shown, fixing the flexible band A to the clamping assembly specifically includes fixing the flexible band A to a predetermined position on the clamping assembly. Conversely, pressing the second cover plate 52 onto the flexible band A and pulling the connecting segment A1 of the flexible band A back to the position corresponding to the operation window specifically includes pressing the second cover plate 52 onto the flexible band A to pull the end of the connecting segment A1 of the flexible band A back to the position corresponding to the operation window.

[0123] Figure 7Region IVa in this embodiment is the predetermined position. By measuring the relative position of the flexible belt fixing fixture and the flexible belt A, the optimal clamping position of the clamping component on the flexible belt A is obtained. Thus, the operator can first measure the predetermined position on the flexible belt A so that the clamping component is clamped in this region. When the first cover plate 51 and the second cover plate 52 are pressed together in sequence, the end of the connecting section A1 corresponds exactly to the operating window 411 (e.g., Figure 9 (As shown in dashed box H), so that the sewing machine can sew it together.

[0124] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can be modified and varied in various ways. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of protection of the present invention.
