Description

Technical Field

[0001] This invention relates to the field of watch strap processing methods, and particularly to a method for positioning, fixing, and processing a watch strap structure. Background Technology

[0002] Watch straps, as the key part that secures a watch to the wrist, come in many varieties, such as metal straps, leather straps, and rubber straps. Currently, many metal straps are increasingly being manufactured using 3D printing. After manufacturing, most straps require surface treatments or finishing processes such as polishing, grinding, engraving, spraying, and diamond setting.

[0003] 3D printed chains are prone to shrinkage, have curved surfaces, and are connected in a movable manner between multiple chain units. During processing, the chain as a whole cannot maintain a stable shape. All of these factors make subsequent processing of the chain extremely difficult, complex, and prone to low positioning accuracy.

[0004] Therefore, it is necessary to provide a method for positioning, fixing, and processing the watch strap structure to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention provides a method for positioning, fixing, and processing a watch strap structure, in order to solve the problems of difficult positioning and fixing, complex operation, and low positioning accuracy in the subsequent processing of the strap in the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows: a method for positioning, fixing, and processing a watch strap structure, which uses a positioning and fixing fixture to position and fix multiple movable strap units. Each strap unit has a fixing rod on one side. The positioning and fixing fixture includes a positioning plate and a limiting plate connected to each other. The side of the positioning plate facing the limiting plate has a positioning groove, and the side of the limiting plate away from the positioning plate has a glue groove. The limiting plate has a limiting hole that penetrates and communicates with the glue groove. The method for positioning, fixing, and processing the watch strap structure includes the following steps: Step S11: Position the multiple movable chain belt units in the positioning slot; Step S12: Connect the limiting plate to the positioning plate, and simultaneously insert the fixing rod into the limiting hole, with the fixing rod extending into the glue groove; Step S13: Inject glue into the glue tank. After the glue hardens, remove the chain belt unit and the limiting plate together for subsequent processing of the chain belt unit.

[0007] In this invention, the diameter of the limiting hole is larger than the outer diameter of the fixing rod, and step S12 further includes: A barrier paste is applied to the outer periphery of the fixing rod. When the fixing rod is inserted into the limiting hole, the barrier paste fills the gap between the fixing rod and the limiting hole.

[0008] In this invention, a slot is provided on the outer periphery of one end of the fixing rod that extends into the glue groove, and the glue fills the slot.

[0009] In this invention, the side of the positioning plate facing the limiting plate is provided with a positioning post, and the limiting plate is provided with a positioning hole for positioning and insertion with the positioning post. Step S12 further includes: The limiting plate and the positioning plate are connected by the positioning engagement of the positioning pin and the positioning hole.

[0010] In this invention, the side of the positioning plate facing the limiting plate is provided with a plurality of limiting posts; Step S12 further includes: When the limiting plate and the positioning plate are connected, the limiting plate contacts the limiting post, and the limiting plate is at a set distance from the chain belt unit.

[0011] In this invention, the side of the chain belt unit facing away from the fixing rod is provided with a fixing hole, the positioning plate is provided with a through hole corresponding to the fixing hole, and a fixing post is detachably provided in the through hole; Step S11 further includes: After the multiple movable chain belt units are positioned in the positioning groove, the fixing post is inserted into the insertion hole, and one end of the fixing post extends into the fixing hole.

[0012] Each of the chain belt units has multiple fixing holes on the side facing away from the fixing rod, and the multiple fixing holes are arranged at an axial angle relative to each other.

[0013] Furthermore, step S13 also includes: After removing the fixing post, take out the chain belt unit and the limiting plate together, and then perform subsequent processing on the fixing hole of the chain belt unit.

[0014] In this invention, the fixing rods of the plurality of chain belt units are arranged in a ring within the glue groove.

[0015] In this invention, the method for positioning, fixing, and processing the watch strap structure further includes step S14: After the chain belt unit is processed, the chain belt unit and the fixing rod are cut and separated.

[0016] Compared with the prior art, the beneficial effects of this invention are as follows: The positioning, fixing and processing method of the watch strap structure of this invention positions multiple strap units through the positioning groove of the positioning plate, then connects the limiting plate to the positioning plate, and simultaneously inserts the fixing rod into the limiting hole, with the fixing rod extending into the glue groove. Then, glue is injected into the glue groove. After the glue hardens, it can form a fixed connection between the multiple fixing rods and the limiting plate, realizing the positioning and stable fixing of multiple strap units. Afterwards, the strap units and the limiting plate are taken out together, and the strap units can be processed subsequently. The operation is convenient and the positioning and fixing effect is good. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The directional terms mentioned in this invention, such as "up", "down", "front", "back", "left", "right", "inner", "outer", "side", "top" and "bottom", are only for reference to the orientation of the accompanying drawings. The directional terms used are for the purpose of explaining and understanding this invention, and are not intended to limit this invention.

[0024] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, a connection can be a detachable connection or a connection of an integral structure; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components or an interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] 3D printed chains can shrink, and the surface of the chain is curved. Multiple chain units are connected by movable connections. These factors make it very difficult to position and fix the chain during subsequent processing in the current technology. The operation is complicated and the positioning accuracy is low.

[0026] The following is a preferred embodiment of a positioning, fixing, and processing method for a watch strap structure that can solve the above-mentioned technical problems provided by the present invention.

[0027] Please refer to Figure 1 , Figure 2 and Figure 3 In the diagram, units with similar structures are represented by the same labels.

[0028] This embodiment provides a method for positioning, fixing, and processing a watch strap structure. It uses a positioning and fixing fixture to position and fix multiple movable strap units 11. Please refer to [reference needed]. Figure 4 Each chain unit 11 has a fixing rod 111 on one side.

[0029] Please refer to Figure 3 The positioning and fixing fixture includes a positioning plate 12 and a limiting plate 13 connected to each other. The side of the positioning plate 12 facing the limiting plate 13 is provided with a positioning groove 121, and the side of the limiting plate 13 away from the positioning plate 12 is provided with a glue groove 131. The limiting plate 13 is provided with a limiting hole 132 that penetrates and communicates with the glue groove 131.

[0030] Please refer to Figure 1 The positioning, fixing, and processing method of the watch strap structure in this embodiment includes the following steps: Step S11: Position the multiple movable chain belt units 11 in the positioning groove 121 to form the initial positioning of the multiple chain belt units 11.

[0031] Step S12: Connect the limiting plate 13 to the positioning plate 12, and at the same time insert the fixing rod 111 into the limiting hole 132, and extend the fixing rod 111 into the glue groove 131.

[0032] Step S13: Inject glue into the glue tank 131. After the glue hardens, it can fix the multiple fixing rods 111 to the limiting plate 13, thereby achieving the positioning and stable fixation of multiple chain belt units 11 with good positioning and fixation effect. Then, remove the chain belt units 11 and the limiting plate 13 together, and the chain belt units 11 can be further processed.

[0033] The positioning, fixing, and processing method of the watch strap structure in this embodiment further includes step S14: After the chain belt unit 11 is processed, the chain belt unit 11 and the fixing rod 111 are cut and separated. That is, after the auxiliary positioning and fixing function of the fixing rod 111 is used up, the fixing rod 111 can be cut off to obtain the processed chain belt unit 11.

[0034] In this embodiment, the multiple chain belt units 11 are distributed at four corners, but it is understood that the connection structure of the multiple chain belt units 11 is not limited to this.

[0035] In this embodiment, the diameter of the limiting hole 132 is larger than the outer diameter of the fixing rod 111. This allows multiple fixing rods 111 to be easily inserted into the corresponding limiting holes when the limiting plate 13 is connected to the positioning plate 12, thus improving the ease of operation.

[0036] In this embodiment, step S12 further includes: A barrier grease is applied to the outer periphery of the fixing rod 111. When the fixing rod 111 is inserted into the limiting hole 132, the barrier grease fills the gap between the fixing rod 111 and the limiting hole 132. The barrier grease prevents the glue in the glue groove 131 from flowing out of the limiting hole 132 and contaminating the chain belt unit 11. It also improves the stability of the fit between the fixing rod 111 and the limiting hole 132.

[0037] The barrier paste can be a wax or a solid oil that can be melted by heating.

[0038] Please refer to Figure 4 In this embodiment, a slot 1111 is provided on the outer periphery of one end of the fixing rod 111 that extends into the glue groove 131, and glue fills the slot 1111. This allows the fixing rod 111 to form a stable connection with the hardened glue.

[0039] Please refer to Figure 3 In this embodiment, the side of the positioning plate 12 facing the limiting plate 13 is provided with a positioning post 122, and the limiting plate 13 is provided with a positioning hole 133 for positioning and insertion with the positioning post 122.

[0040] Step S12 also includes: The limiting plate 13 and the positioning plate 12 are connected by the positioning engagement of the positioning pin 122 and the positioning hole 133.

[0041] In this embodiment, the side of the positioning plate 12 facing the limiting plate 13 is provided with a plurality of limiting posts 123.

[0042] Step S12 also includes: When the limiting plate 13 and the positioning plate 12 are connected, the limiting plate 13 contacts the limiting post 123, and the limiting plate 13 is at a set distance from the chain belt unit 11.

[0043] In this embodiment, a fixing hole is provided on the side of the chain belt unit 11 facing away from the fixing rod 111 (the fixing hole is located at...). Figure 3 The bottom surface of the mid-chain unit 11), the positioning plate 12 is provided with a through hole 124 corresponding to the fixing hole, and a fixing post 14 is detachably provided in the through hole 124. The fixing post 14 and the through hole 124 can be an interference fit with a certain interference force.

[0044] Step S11 also includes: After multiple movable chain belt units 11 are positioned in the positioning groove 121, a fixing post 14 is inserted into the insertion hole 124, and one end of the fixing post 14 extends into the fixing hole, thereby further positioning and fixing the chain belt unit 11 in the positioning groove 121.

[0045] Each chain belt unit 11 has multiple fixing holes on the side facing away from the fixing rod 111, and the axial direction of the fixing holes is relatively inclined. The insertion through hole 124 is also inclined to correspond to the fixing hole, and different fixing posts 14 extend and connect to the fixing hole of the chain belt unit 11 at different inclination angles. This makes it difficult for the chain belt unit 11 to fall out of the positioning groove 121, and the chain belt unit 11 can be stably positioned and fixed in the positioning groove 121.

[0046] Furthermore, step S13 also includes: After removing the fixing post 14, take out the chain belt unit 11 and the limiting plate 13 together, and then perform subsequent processing on the fixing hole of the chain belt unit 11.

[0047] In this embodiment, the fixing rods 111 of multiple chain belt units 11 are arranged in a ring within the glue groove 131, and the multiple fixing rods 111 can form a uniform and stable connection with the hardened glue.

[0048] In this embodiment, the outer plane of the hardened adhesive is flush with the side of the limiting plate 13 that faces away from the positioning plate 12. This allows the side of the limiting plate 13 with adhesive to be stably placed on the fixed plane, and then the chain belt unit 11 can be processed.

[0049] In this embodiment, the glue tank 131 is provided with a conical inner wall surface. The inner diameter of the conical inner wall surface is smaller at the end near the chain belt unit, which facilitates the subsequent removal of the hardened glue from the glue tank 131.

[0050] The preferred embodiment of the watch strap structure positioning, fixing, and processing method uses the positioning groove 121 of the positioning plate 12 to position multiple strap units 11. Simultaneously, by inserting a fixing post 14 into the insertion hole 124 and extending one end of the fixing post 14 into the fixing hole, the strap units 11 are further positioned and fixed within the positioning groove 121. Then, the limiting plate 13 is connected to the positioning plate 12, and the fixing rod 111 is inserted into the limiting hole 132, and the fixing rod 111 extends into the glue groove 131. Then, glue is injected into the glue groove 131. After the glue hardens, the glue can form a fixed connection between the multiple fixing rods 111 and the limiting plate 13, thereby achieving the positioning and stable fixing of multiple chain belt units 11.

[0051] Then, the chain belt unit 11 and the limiting plate 13 are removed together, and the chain belt unit 11 can be further processed. After the chain belt unit 11 is processed, the chain belt unit 11 and the fixing rod 111 are cut and separated to obtain the processed chain belt unit 11.

[0052] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
