Watch strap processing fixture and watch strap processing method

Abstract

This invention relates to the field of watch strap processing technology, specifically disclosing a watch strap processing fixture and a watch strap processing method. The fixture has a first groove and a second groove on its base, with the first groove accommodating a first loop and the second groove accommodating a watch strap, thus limiting the width of the first loop and the watch strap. A first positioning component fixes the end of the first loop away from the fold, limiting its length. A second loop is limited in its length by having its end away from the fold wrap around the free end of the watch strap and fixed above the second groove by the second positioning component. This also allows the second loop to bend at the point where it wraps around the watch strap. A gasket presses a portion of the second loop against a second surface, ensuring the relative position of the first loop, the second loop, and the watch strap is stable and the bending position is precise.

Description

Technical Field

[0001] This invention relates to the field of watch strap processing technology, and in particular to a watch strap processing fixture and a watch strap processing method. Background Technology

[0002] Watch straps are typically made of metal, leather, or woven fiber materials. Some watches with straps made of woven fiber materials also come with a lanyard, which is also made of woven fiber material. The lanyard serves both a decorative purpose and adds variety to the watch's applications.

[0003] In existing technologies, the lanyard and watch strap are typically assembled manually. Specifically, the raw material for the lanyard is usually a long strip of sheet fiber. The middle part of the fiber strip needs to be heat-pressed to the watch strap first, and then the fiber strip needs to be bent and laser-cut multiple times. Finally, the two ends of the cut fiber strip are connected to form the lanyard. However, existing technologies usually rely on manual bending of the fiber strip, which makes it difficult to guarantee the positioning accuracy of the bent part of the fiber strip, thus making it difficult to guarantee the quality of the product, and also resulting in low production efficiency. Summary of the Invention

[0058] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0059] In existing technologies, the lanyard and watch strap are typically assembled manually. Specifically, the raw material for the lanyard is usually a long strip of sheet fiber. The middle part of the fiber strip needs to be heat-pressed to the watch strap first, and then the fiber strip needs to be bent and laser-cut multiple times. Finally, the two ends of the cut fiber strip are connected to form the lanyard. However, existing technologies usually rely on manual bending of the fiber strip, which makes it difficult to guarantee the positioning accuracy of the bent part of the fiber strip, thus making it difficult to guarantee the quality of the product, and also resulting in low production efficiency.

[0060] To address this issue, this embodiment provides a watch strap processing fixture for processing semi-finished watch straps.

[0061] like Figure 1 and Figure 2 As shown, the semi-finished watch strap 10 includes a watch strap 101 and a loop strap, the loop strap including a first loop 102 folded in half and a second loop 103.

[0062] The watch strap 101 has a first surface 1011 and a second surface 1012 disposed opposite to each other. The fold 104 of the loop strap is fixed to the first surface 1011 of the watch strap 101, and the second loop 103 is located between the first loop 102 and the loop strap. The fold 104 is the overlapping portion of the first loop 102 and the second loop 103. In this embodiment, the fold 104 is adjacent to the end of the watch strap 101.

[0063] like Figure 3 As shown Figure 9 As shown, the watch strap processing fixture includes a base 1, a first positioning component 2, a second positioning component 3, and a gasket 41.

[0064] like Figure 3As shown, the base 1 has a first groove 11 for accommodating the first loop 102 and a second groove 12 for accommodating the watch strap 101. Specifically, the first groove 11 and the second groove 12 are connected. The first groove 11 has a first bottom wall 111 and two first side walls 112 located on both sides of the first bottom wall 111. The second groove 12 has a second bottom wall 121 and two second side walls 122 located on both sides of the second bottom wall 121. When the first loop 102 is accommodated in the first groove 11, the first loop 102 fits against the first bottom wall 111, and the two first side walls 112 respectively abut against the two sides of the width direction of the first loop 102 to restrict the movement of the first loop 102 along its width direction. When the watch strap 101 is accommodated in the second groove 12, the fold 104 and the portion of the watch strap 101 away from the fold 104 can fit against the second bottom wall 121, and the two second side walls 122 respectively abut against the two sides of the width direction of the watch strap 101 to restrict the displacement of the watch strap 101 in its width direction. The width directions of the first loop 102 and the watch strap 101 are as follows: Figure 3 The ab direction is shown in the diagram.

[0065] In this embodiment, the widths of the first ring 102 and the second ring 103 are equal, and the widths of the first ring 102 and the second ring 103 are not equal to the width of the watch strap 101. This also forms a step at the connection between the first groove 11 and the second groove 12 to limit the length of the watch strap 101.

[0066] like Figures 3 to 6 , Figure 8 and Figure 9 As shown, the first positioning component 2 is disposed on the base 1 and is used to fix the end of the first loop 102 away from the fold 104. Optionally, the first positioning component 2 includes a first positioning post 21 and a second positioning post 22 protruding from the base 1. The first positioning post 21 is used to insert into the first positioning hole 1021 disposed in the first loop 102, and the second positioning post 22 is used to insert into the second positioning hole 1022 disposed in the first loop 102, thereby limiting the first loop 102 in its length direction. The length direction of the first loop 102 is as follows: Figure 3 As shown in the cd direction. In this embodiment, the diameters of the first positioning post 21 and the second positioning post 22 are different, which can prevent mistaken installation and avoid reverse installation. In other embodiments, the first positioning component 2 can also be replaced by an elbow clamp, which presses the first ring band 102 against the first bottom wall 111.

[0067] Optionally, such as Figure 12As shown, the first positioning component 2 also includes a first slider 23 slidably connected to the base 1, a first fixing block 25 disposed on the base 1, a first boss 26 disposed on the first slider 23, a first spring (not shown in the figure) disposed between the first fixing block 25 and the first slider 23, and a first baffle 24 disposed on the base 1. The base 1 is provided with a first sliding groove 18 and a first elongated hole 15 communicating with the first sliding groove 18. The first baffle 24 closes the opening of the first sliding groove 18. The first slider 23 is located in the first sliding groove 18. The first boss 26 passes through the first elongated hole 15. The first positioning post 21 and the second positioning post 22 are both fixed to the first boss 26. The first slider 23 can drive the first boss 26 to move along the length direction of the first elongated hole 15. The first spring is always in a compressed state and is configured to make the first slider 23 always have a tendency to move away from the second positioning component 3. With this configuration, when installing the first ring band 102, by pushing the first slider 23 to move it to a suitable position closer to the second positioning component 3, the first positioning hole 1021 and the second positioning hole 1022 of the first ring band 102 are respectively fitted onto the first positioning post 21 and the second positioning post 22. After releasing the first slider 23, driven by the first spring, the first slider 23, through the first boss 26, drives the first positioning post 21 and the second positioning post 22 to move away from the second positioning component 3 along the length direction of the first ring band 102. This allows the first ring band 102 to be tensioned automatically and can also accommodate first ring bands 102 of different lengths. In other embodiments, the first spring can also be replaced by a first magnet (not shown in the figure) disposed on the first fixing block 25 and a second magnet (not shown in the figure) disposed on the first slider 23. The ends of the first magnet and the second magnet with the same magnetic properties face each other. Under the interaction of the first magnet and the second magnet, the first slider 23 always has the ability to drive the first positioning post 21 and the second positioning post 22 to move away from the second positioning component 3, thus achieving the same effect.

[0068] like Figures 3 to 9 As shown, the second positioning component 3 is disposed on the base 1 and located above the second groove 12. The second positioning component 3 is used to fix the end of the second loop 103 away from the fold 104, so that the second loop 103 can wrap around the free end of the watch strap 101 and be located above the second surface 1012. Before fixing the second loop 103 by the second positioning component 3, the second loop 103 needs to be wrapped around the free end of the watch strap 101 and bent so that the second loop 103 wraps around to the top of the second surface 1012 of the watch strap 101, and then the second loop 103 is fixed by the second positioning component 3. One end of the watch strap 101 is a connecting end for rotatable connection with the watch case, and the other end is a free end for connection with the mating watch strap 101.

[0069] In this embodiment, the second positioning component 3 includes a third positioning post 31 and a fourth positioning post 32. The third positioning post 31 is used to insert into the third positioning hole 1031 disposed in the second ring belt 103, and the fourth positioning post 32 is used to insert into the fourth positioning hole 1032 disposed in the second ring belt 103. This allows the second ring belt 103 to be limited in its length direction. The length direction of the second ring belt 103 is as follows: Figure 3 As shown in the cd direction. In other embodiments, the second positioning component 3 may also be replaced by an elbow clamp.

[0070] like Figures 3 to 8 As shown, the gasket 41 is detachably mounted on the base 1 and located above the second groove 12. The gasket 41 has a hot-pressing position. When the gasket 41 is in the hot-pressing position, it is used to press a portion of the second loop 103 against the second surface 1012, ensuring the stability of the positions of the second loop 103 and the watch strap 101 during the hot-pressing operation. Specifically, the base 1 is provided with a positioning pin 13, and the gasket 41 is provided with a first positioning pin hole 411, which is inserted into the positioning pin 13.

[0071] The watch strap processing fixture provided in this embodiment limits the width of the first loop 102 and the watch strap 101 by providing a first groove 11 and a second groove 12 on the base 1. The first groove 11 accommodates the first loop 102 and the second groove 12 accommodates the watch strap 101. The first positioning component 2 fixes the end of the first loop 102 away from the fold 104, thus limiting the length of the first loop 102. The second loop 103 is limited in length by having its end away from the fold 104 pass around the free end of the watch strap 101 and fixed above the second groove 12 by the second positioning component 3. The second loop 103 is also bent at the position where it passes around the watch strap 101. A portion of the second loop 103 is pressed against the second surface 1012 by the gasket 41, ensuring the relative position of the first loop 102, the second loop 103, and the watch strap 101 is stable and the bending position is accurate.

[0072] Optionally, to ensure the relative position stability of the gasket 41 and the base 1, the watch strap processing fixture also includes a clamping block 42. The clamping block 42 is provided with a second positioning pin hole 421, which can also be inserted and engaged with the positioning pin 13. The clamping block 42 is also detachably connected to the base 1 to maintain the phase position of the gasket 41 and the base 1. The clamping block 42 can be detachably connected to the base 1 by magnetic attraction, or it can be detachably connected by screws passing through the clamping block 42 and threadedly connected to the base 1.

[0073] Optionally, such as Figures 3 to 6 , Figure 8 and Figure 9 As shown, the watch strap processing fixture also includes a first pressure plate assembly 5. The first pressure plate assembly 5 includes a first pressure plate 51 rotatably connected to the base 1, and a first buckle 52 movably disposed on the base 1. A portion of the first pressure plate 51 is located above the first groove 11 and is used to press the first loop 102 against the base 1. Another portion of the first pressure plate 51 is located above the second groove 12 and is used to press the watch strap 101 against the base 1. The first buckle 52 is used to lock or unlock the relative position of the first pressure plate 51 and the base 1. With this configuration, the watch strap 101 and the first loop 102 can be pressed simultaneously by the first pressure plate assembly 5 to ensure that their positions relative to the base 1 are stable. Specifically, in this embodiment, when the first pressure plate 51 presses the first loop 102 against the base 1 and simultaneously presses the watch strap 101 against the base 1, the first pressure plate 51 rotates to a position that fits against the base 1.

[0074] Optionally, such as Figure 10 As shown, the first latch 52 includes a handle rod 521 rotatably mounted on the base 1, a clamping seat 522 slidably sleeved on the handle rod 521, a bolt 523 threadedly connected to the handle rod 521, a handle cap 524 clamped between the bolt 523 and the handle rod 521, and a compression spring 525 sleeved on the handle rod 521. The handle cap 524 covers the clamping seat 522, and the compression spring 525 is located inside the handle cap 524 with its two ends abutting against the handle cap 524 and the clamping seat 522 respectively. Driven by the compression spring 525, the clamping seat 522 always tends to move away from the handle cap 524. The first pressure plate 51 is provided with a groove 511. When the first pressure plate 51 is rotated to fit against the base 1, the pressing seat 522 can be manually compressed into the handle cap 524, and the handle rod 521 can be rotated into the groove 511 to release the pressing seat 522. Under the action of the compression spring 525, the pressing seat 522 can press the first pressure plate 51 against the base 1. Preferably, the first pressure plate assembly 5 also includes a limiting post 53 provided on the base 1. The first pressure plate 51 is provided with a limiting hole 512. When the first pressure plate 51 is rotated to fit against the base 1, the limiting post 53 and the limiting hole 512 are inserted to ensure the stability of the position of the first pressure plate 51.

[0075] Optionally, such as Figures 3 to 6 , Figure 8 and Figure 9As shown, the watch strap processing fixture also includes a second pressure plate assembly 6 located above the first groove 11. The second pressure plate assembly 6 includes a second pressure plate 61 rotatably connected to the base 1, and a second buckle 62 movably disposed on the base 1. The second pressure plate 61 is used to press the first loop 102 against the base 1, and the second buckle 62 is used to lock or unlock the relative position of the second pressure plate 61 and the base 1. This further ensures the stability of the position of the first loop 102. Specifically, the first pressure plate assembly 6 is located between the first positioning assembly 2 and the second pressure plate assembly 6, and the second buckle 62 is rotatably disposed on the base 1. When the second pressure plate assembly 6 presses the portion of the second loop 103 located between the first positioning assembly 2 and the second pressure plate assembly 6 against the first bottom wall 111 of the first groove 11, the phase position of the second pressure plate 61 and the base 1 can be locked by rotating the second buckle 62 to engage with the second pressure plate 61.

[0076] Optionally, such as Figures 3 to 9 As shown, the watch strap processing fixture also includes a third pressure plate assembly 7 located above the second groove 12. The third pressure plate assembly 7 includes a third pressure plate 71 rotatably connected to the base 1, and a third buckle 72 movably disposed on the base 1. The third pressure plate 71 is used to press the watch strap 101 tightly against the base 1, and the third buckle 72 is used to lock or unlock the relative position of the third pressure plate 71 and the base 1. This arrangement can further ensure the stability of the positioning of the watch strap 101. The third positioning post 31 and the fourth positioning post 32 of the second positioning assembly 3 are both disposed on the third pressure plate 71, which helps to reduce the number of parts in the watch strap processing fixture. The third buckle 72 is rotatably disposed on the base 1. Preferably, the third pressure plate assembly 7 further includes a fourth pressure plate 73 rotatably disposed on the third pressure plate 71. The fourth pressure plate 73 is used to press the second ring belt 103 against the third pressure plate 71, and the third buckle 72 can lock or unlock the third pressure plate 71 and the fourth pressure plate 73 simultaneously to the base 1, which can further improve the stability of the positioning of the second ring belt 103.

[0077] Optionally, such as Figure 14As shown, the third pressure plate assembly 7 also includes a second slider 74 slidably connected to the base 1, a second fixing block 76 disposed on the base 1, a second boss 77 and a third boss 78 both disposed on the second slider 74, a second spring (not shown in the figure) disposed between the second fixing block 76 and the second slider 74, and a second baffle 75 disposed on the base 1. The base 1 has a second sliding groove 27 and a second elongated hole 16 and a third elongated hole 17 both communicating with the second sliding groove 27. The second baffle 75 closes the opening of the second sliding groove 27, the second slider 74 is located within the second sliding groove 27, and the second boss 77 passes through the second elongated hole 78. The third boss 78 passes through the third elongated hole 17, the third pressure plate 71 is rotatably mounted on the second boss 77, the third boss 78 is provided with a positioning pin 79, and the third buckle 72 is rotatably mounted on the third pressure plate 71. When the third pressure plate 71 presses the watch strap 101 tightly onto the base 1, the third pressure plate 71 is inserted into the positioning pin 79. The second slider 74 can drive the second boss 77 and the third boss 78 to move simultaneously along the length direction of the second elongated hole 16 and the third elongated hole 17. The second spring is always in a compressed state and is configured to make the second slider 74 always have a tendency to move away from the first positioning component 2. With this configuration, when installing the second ring band 102, the third pressure plate 71 is first rotated to fit against the base plate 1. At this time, the third pressure plate 71 can press the watch band 101 tightly against the base 1, and the third pressure plate 71 and the positioning pin 79 are inserted. Then, by pushing the second slider 74 to move it to the appropriate position closer to the first positioning component 2, the third positioning hole 1031 and the fourth positioning hole 1032 of the second ring band 103 are respectively fitted onto the third positioning pin 31 and the fourth positioning pin 32. Then, the second ring band 103 is pressed by the fourth pressure plate 73, and the third pressure plate 71 and the fourth pressure plate 73 are locked simultaneously by the third buckle 72. At this time, the second slider 74 can be released. After the second slider 74 is released, under the drive of the second spring, the second slider 74 drives the third pressure plate component 7 and the second positioning component 3 installed on the third pressure plate component 7 to move simultaneously away from the first positioning component 2, which can tighten the second ring band 103. In other embodiments, the second spring can also be replaced by a third magnet (not shown in the figure) disposed on the second fixing block 76 and a fourth magnet (not shown in the figure) disposed on the second slider 74. The ends of the third magnet and the fourth magnet with the same magnetic properties are opposite each other. Under the interaction of the third magnet and the fourth magnet, the second slider 74 always has the ability to drive the second positioning component 3 to move away from the first positioning component 2, which can also achieve the above-mentioned effect.

[0078] Optionally, such as Figures 3 to 5 ,as well as Figure 13As shown, the watch strap processing fixture also includes a first hot pressing block 81. The gasket 41 has a recessed groove 412. When the gasket 41 is in the hot pressing position, the first hot pressing block 81 passes through the recessed groove 412 to hot press the second loop 103 and the watch strap 101, so that the second loop 103 and the watch strap 101 form a preliminary connection area. Because the gasket 41 can press the second loop 103 and the watch strap 101 together, a smooth pressing effect can be ensured when the first hot pressing block 81 hot presses the second loop 103 and the watch strap 101 through the recessed groove 412.

[0079] Optionally, such as Figure 7 As shown, the pad 41 also has a laser cutting position. When the pad 41 is in the laser cutting position, the pad 41 is located between the second ring 103 and the watch strap 101, and the initial connection area can be inserted into the relief groove 412. The laser cutting equipment can cut the second ring 103 directly above the pad 41 to avoid damaging the watch strap 101 below.

[0080] Optionally, such as Figures 3 to 5 As shown, the base 1 is provided with a guide hole 14, and the first hot pressing block 81 is provided with a first guide post 811, which can be inserted into the guide hole 14; this ensures the fitting accuracy between the first hot pressing block 81 and the base 1, thereby ensuring the pressing accuracy of the first hot pressing block 81. Figure 9 and Figure 13 As shown, the watch strap processing fixture also includes a second hot pressing block 82. The second hot pressing block 82 is provided with a second guide post 821, which can be inserted into the guide hole 14. The second hot pressing block 82 is used to hot press the second loop 103 and the watch strap 101 to form a final connection area between the second loop 103 and the watch strap 101, and the final connection area covers the initial connection area. In this embodiment, the pressing surface of the second hot pressing block 82 is larger than the pressing surface of the first hot pressing block 81 and can completely cover the pressing surface of the first hot pressing block 81. By having both the second guide post 821 and the first guide post 811 inserted into the guide hole 14, the positional accuracy of the second hot pressing block 82 and the first hot pressing block 81 when pressing the second loop 103 and the watch strap 101 can be guaranteed. By using the first hot pressing block 81 and the second hot pressing block 82 to hot press the second loop 103 and the watch strap 101 step by step, the pressing quality of the final connection area can be significantly improved, and wrinkles at the pressing position can be avoided.

[0081] Optionally, such as Figure 11As shown, both the first hot pressing block 81 and the second hot pressing block 82 can abut against the first pressure plate 51 along the extending direction of the guide hole 14. This arrangement allows the first pressure plate 51 to limit the movement of the first hot pressing block 81 and the second hot pressing block 82, preventing excessive movement during hot pressing and thus reducing the quality of the hot pressing. It also avoids the need for separate components to limit the movement of the first hot pressing block 81 and the second hot pressing block.

[0082] This embodiment also provides a method for processing watch straps, which includes the following steps:

[0083] S10: Provide a semi-finished watch strap 10 and the aforementioned watch strap processing fixture.

[0084] S20: Clamping and positioning.

[0085] Specifically, S20 includes the following steps:

[0086] S210: Place the first loop 102 in the first slot 11 and place the watch strap 101 in the second slot 12.

[0087] like Figure 4 As shown, the first loop 102 is laid flat in the first groove 11, and the watch strap 101 is placed in the second groove 12. The first groove 11 limits the width of the first loop 102, and the second groove 12 limits the width of the watch strap 101. The adjustment between the first groove 11 and the second groove 12 limits the length of the watch strap 101.

Then the first slider 23 is released. Driven by the first spring, the first slider 23 drives the first positioning post 21 and the second positioning post 22 to move away from the second positioning component 3 through the first boss 26, which can tighten the first ring belt 102 by itself.

[0090] S230: The second loop 103 is wrapped around the free end of the watch strap 101 and fixed by the second positioning component 3.

[0091] Specifically, such as Figures 4 to 6 As shown, S230 includes:

[0092] S2301: Rotate the third pressure plate 71 to press the second ring 103 and watch strap 101 onto the base 1, and the third pressure plate 71 and the positioning pin 79 are inserted into each other.

[0093] S2302: Insert the third positioning hole 1031 and the fourth positioning hole 1032 on the second ring belt 103 into the third positioning post 31 and the fourth positioning post 32 respectively.

[0094] Specifically, by pushing the second slider 74 to move it to a suitable position closer to the first positioning component 2, the third positioning hole 1031 and the fourth positioning hole 1032 of the second ring belt 103 are respectively fitted onto the third positioning post 31 and the fourth positioning post 32.

[0095] S2303: Rotate the fourth pressure plate 73 to press the second ring belt 103 against the third pressure plate 71.

[0096] S2304: Rotate the third buckle 72 to lock the third pressure plate 71 and the fourth pressure plate 73 to the base 1 simultaneously.

[0097] When the third latch 72 locks the third pressure plate 71 and the fourth pressure plate 73 simultaneously, the second slider 74 can be released. After the second slider 74 is released, driven by the second spring, the second slider 74 drives the third pressure plate assembly 7 and the second positioning assembly 3 installed on the third pressure plate assembly 7 to move away from the first positioning assembly 2 at the same time through the second boss 77 and the third boss 78, which can tighten the second ring belt 103.

[0098] S240: Install gasket 41 into the hot-press position.

[0099] Specifically, such as Figure 4 and Figure 5 As shown, S240 includes the following steps:

[0100] S2401: Insert the first positioning pin hole 411 on the gasket 41 into the positioning pin 13 on the base 1, and press the second ring 103 onto the watch strap 101 through the gasket 41.

[0101] S2402: Insert the second positioning pin hole 421 of the clamping block 42 into the positioning pin 13, and lock the relative position of the clamping block 42 and the base 1, so as to lock the relative position of the gasket 41 and the base 1 through the clamping block 42.

[0104] S222: Rotate the second pressure plate 61 to press the portion of the first ring belt 102 located between the first positioning component 2 and the first pressure plate component 5 against the first bottom wall 111 of the first groove 11, and lock the relative position of the second pressure plate 61 and the base 1 by the second buckle 62.

[0105] Alternatively, the watch strap manufacturing method may also include:

[0106] S30: First hot pressing.

[0107] like Figure 5 and Figure 6 As shown, the first hot pressing block 81 passes through the relief groove 412 provided on the gasket 41 to perform initial hot pressing on the second ring 103 and the watch strap 101, forming a preliminary connection area, and then the first hot pressing block 81 is removed.

[0108] S40: Laser cutting.
