[0046] Example

[0047] Please refer to Figure 1-7 As shown, this embodiment provides a sewing template for upper accessories, including a base plate 1, a positioning plate 2 and a clamping assembly 3. The base plate 1 is connected to an external workbench and is located under the head of the sewing machine. The positioning plate 2 is rotatably set on the base plate 1, and a placement position 21 and a drive block 22 are provided on the positioning plate 2. The clamping assembly 3 is placed on the placement position 21. The height of the drive block 22 and the height of the needle of the sewing machine have an interactive part, that is, the drive block 22 and the needle have a certain overlap in the horizontal direction, which facilitates the subsequent mutual contact between the needle and the drive block 22. The clamping assembly 3 includes a first plate 31 and a second plate 32, and one side of the second plate 32 is connected to the first plate 31. The first plate 31 and the second plate 32 are respectively provided with a first sewing channel 311 and a second sewing channel 321 corresponding to each other, and the first sewing channel 311 and the second sewing channel 321 correspond to the position of the needle. The first and second accessories of the upper accessories are respectively arranged on the inner side surfaces of the first plate 31 and the second plate 32 corresponding to each other, and are respectively covered on the first sewing channel 311 and the second sewing channel 321.

[0048] The first plate 31 and the second plate 32 clamp the first accessory and the second accessory therein, positioning the two to ensure the accuracy of their relative positions during the sewing process and improve the sewing qualification rate; the positioning plate 2 carries the clamping component 3, and the machine head descends to sew the first accessory and the second accessory through the second sewing channel 321. At the same time, the positioning plate 2 is rotatably set on the base plate 1. By rotating, the position of the sewn clamping component 3 and the unsewn clamping component 3 can be exchanged to achieve uninterrupted sewing and improve production efficiency.

[0049] Furthermore, by setting the driving block 22 on the positioning plate 2, it is ensured that the driving block 22 and the needle of the sewing machine are at the same horizontal height. By controlling the movement of the machine head, the side of the needle and the driving block 22 are pressed against each other, and a force is applied to the driving block 22 to drive the positioning plate 2 to rotate, thereby realizing the position exchange of the sewn clamping assembly 3 and the unsewn clamping assembly 3, or the external workbench drives the substrate 1 to move, thereby realizing the pressing between the driving block 22 and the side of the needle, realizing the rotation drive of the positioning plate 2, reducing the number of manpower, and further improving the sewing efficiency.

[0050] Please refer to Figure 1-4 As shown, in this embodiment, an upwardly extending central axis column 12 is provided on the base plate 1, a rotation channel 25 is provided at the center of the positioning plate 2, the central axis column 12 extends upward through the rotation channel 25, and a rotating shaft 13 is provided between the central axis column 12 and the inner side wall of the rotation channel 25. The rotation of the positioning plate 2 is achieved by the rotating shaft 13, and the central axis column 12 limits the positioning plate 2 to ensure that the positioning plate 2 can stably rotate on the base plate 1. Furthermore, a mounting groove 11 is provided on the base plate 1, and the central axis column 12 is provided at the center of the bottom of the mounting groove 11. The positioning plate 2 is rotatably provided in the mounting groove 11, and the inner side wall of the mounting groove 11 cooperates with the central axis column 12 to limit the positioning plate 2, further ensuring that the positioning plate 2 can stably rotate on the base plate 1.

[0051] The number of drive blocks 22 is the same as the number of placement positions 21 and corresponds one to one. In this embodiment, the number of drive blocks 22 and placement positions 21 are both four, and one-to-one corresponding placement positions 21 and drive blocks 22 are set. After each sewing is completed, the corresponding drive block 22 is located on the side of the needle, which is convenient for pressing against the needle and driving the positioning plate 2 to rotate.

[0052] In this embodiment, a placement channel 211 is defined in the placement position 21. A placement step 212 is provided at the inner bottom of the placement channel 211. The bottom surface of the first plate 31 abuts against the placement step 212. The placement channel 211 reduces the weight of the positioning plate 2, thereby reducing the driving force required to rotate the positioning plate 2 and saving energy. It also makes way for the sewing needle, ensuring that the needle can fully penetrate the first and second accessories for sewing, thereby improving the sewing effect.

[0053] Please refer to Figure 2 、 Figure 6 and Figure 7 As shown, further, a first magnetic member 15 is provided on the base plate 1, and a second magnetic member 322 is provided on the second plate 32, and the first magnetic member 15 and the second magnetic member 322 correspond one to one. The second magnetic member 322 and the first magnetic member 15 are attracted to each other to limit the clamping assembly 3 and ensure the stability of the clamping assembly 3 during the sewing process; at the same time, the second plate 32 is located above the first plate 31, and the second magnetic member 322 applies a force toward the first plate 31 to the second plate 32, thereby improving the fit between the first plate 31 and the second plate 32, thereby improving the limiting effect of the first accessory and the second accessory, and further improving the sewing qualification rate. In this embodiment, a magnetic channel 313 is provided on both the first plate 31 and the second plate 32, and the second magnetic member 322 is fixed in the magnetic channel 313 of the second plate 32. The magnetic channel 313 of the first plate 31 gives way to the first magnetic member 15 and the second magnetic member 322, ensuring that a stable magnetic attraction force can be formed between the two. Specifically, the first magnetic member 15 and the second magnetic member 322 are both magnets.

[0054] Please refer to Figure 1-4 As shown, specifically, a positioning block 213 is provided on the placement step 212, and a positioning notch 312 is provided on the side of the first plate 31, and the positioning notch 312 and the positioning block 213 correspond one to one. When the clamping assembly 3 is on the placement position 21, the positioning block 213 is embedded in the positioning notch 312, and the clamping assembly 3 is positioned on the side to ensure the position accuracy of the clamping assembly 3, thereby improving the accuracy of the sewing position of the first accessory and the second accessory. In this embodiment, the positioning plate 2 is circular in shape, and the four placement positions 21 are circumferentially distributed on the circular circumference of the positioning plate 2. The first plate 31 and the second plate 32 are fan-shaped, which improves the space utilization of the positioning plate 2, ensures that the first plate 31 and the second plate 32 have a larger surface area, and can clamp and limit first accessories and second accessories of more sizes. In this embodiment, there are two positioning blocks 213 for placing a step portion 212. The two positioning blocks 213 correspond to the radii on both sides of the first plate 31 respectively, limiting the clamping component 3 on both sides, further improving the position accuracy of the clamping component 3.

[0055] Furthermore, a limit block assembly 23 is provided on the positioning plate 2. The limit block assembly 23 is arranged around the circumference of the placement position 21 and abuts against the circumference of the clamping assembly 3. The limit assembly positions the clamping assembly 3 on the outside and cooperates with the positioning block 213 to further improve the accuracy of the placement of the clamping assembly 3 at the position 21. In this embodiment, the limit block assembly 23 includes a first limit block 231 and two second limit blocks 232. The first limit block 231 is located at the center of the clamping assembly 3 and extends in the radial direction on both sides of the center to limit the top of the clamping assembly 3; the second limit blocks 232 are located at both ends of the bottom edge of the arc of the clamping assembly 3 to limit the clamping assembly 3 at the bottom. Under the premise of ensuring that the clamping assembly 3 can be limited in multiple directions, the size of the limit assembly is reduced, the weight of the positioning plate 2 is further reduced, and the driving force for driving the positioning plate 2 to rotate is reduced.

[0056] In this embodiment, a retaining ring 314 is provided on the inner side of the first plate 31. The retaining ring 314 surrounds the first sewing channel 311. The first accessory is embedded within the retaining ring 314. The inner surface of the retaining ring 314 has the same shape and size as the first accessory. The inner surface of the retaining ring 314 retains the first accessory, ensuring its accurate positioning. A retaining groove 323 is provided on the inner side of the second plate 32. The second sewing channel 321 is formed within the retaining groove 323. The retaining groove 323 corresponds to the position of the retaining ring 314. The second accessory is embedded within the retaining groove 323. The inner surface of the retaining groove 323 has the same shape and size as the second accessory. The inner surface of the retaining groove 323 retains the second accessory, ensuring its accurate positioning. In this embodiment, the size of the second accessory is larger than that of the first accessory, that is, the size of the limiting protrusion 314 is smaller than the size of the limiting groove 323. When the first plate 31 and the second plate 32 are in contact with each other, the limiting protrusion 314 is embedded in the limiting groove 323 and presses against the second accessory, exerting a limiting force on the second accessory, thereby further improving the stability of the second accessory during the sewing process.

[0057] Furthermore, the base plate 1 is provided with a locking block 14, which is located on the peripheral side of the positioning plate 2 and has a locking groove 141 facing the positioning plate 2. The positioning plate 2 is provided with a spring assembly 24, which includes a driving portion 242 and a spring 241 connected to the driving portion 242. The spring 241 protrudes from the positioning plate 2 and conforms to the shape of the locking groove 141. The driving portion 242 applies a force to the spring 241 in the direction of the locking block 14. During the rotation of the positioning plate 2, the spring 241 and the locking block 14 abut against each other. The locking block 14 applies a force to the spring 241 in the direction of the driving portion 242, compressing the driving portion 242 until the spring 241 moves into the locking groove 141. The driving portion 242 rebounds, and the driving spring 241 abuts against the inner side wall of the locking groove 141, thereby achieving the positioning of the positioning plate 2 and ensuring that the placement position 21 of the positioning plate 2 can stably move to the bottom of the machine head. In this embodiment, the number of the locking blocks 14 is four, and the number of the spring block assemblies 24 is two. The two spring block assemblies 24 are located on both sides of the diameter of the positioning plate 2. In one sewing state, the locking grooves 141 of the two locking blocks 14 of the two spring block assemblies 24 respectively press against each other. In the next sewing state, the two spring block assemblies 24 respectively press against the locking grooves 141 of the other two locking blocks 14, ensuring that the positioning plate 2 can be positioned before sewing each clamping assembly 3.

[0058] In this embodiment, the engaging plate is provided with a relief slope 142, which is located on one side of the engaging groove 141. The relief slope 142 slopes from one side of the engaging groove 141 to the other side away from the positioning plate 2. Before positioning, the spring block 241 and the relief slope 142 abut against each other and move along the relief slope 142 toward the engaging groove 141. The relief slope 142 gives way to the spring block 241, preventing the spring block 241 from colliding with the side wall of the engaging block 14 and affecting the continuity of the sewing process.

[0059] In this embodiment, the spring block assembly 24 also includes a lower enclosure plate 243 and an upper enclosure plate 244. The lower enclosure plate 243 is fixed on the positioning plate 2, and the upper enclosure plate 244 is fixed on the top surface of the lower enclosure plate 243. The upper enclosure plate 244 and the lower enclosure plate 243 enclose the driving portion 242 and the spring block 241. Furthermore, the driving portion 242 is a spring, one end of the spring is fixedly connected to the side wall of the enclosure plate, and the other end of the spring is fixedly connected to the spring block 241. The front end openings of the upper enclosure plate 244 and the lower enclosure plate 243 allow the spring block 241 to extend and abut against the engaging groove 141, and guide the spring block 241 at the rear end, upper end and both sides to ensure that the spring block 241 can stably move toward the engaging block 14, thereby avoiding the position of the spring block 241 from being offset and affecting the accuracy of the position of the positioning plate 2.

[0060] Please refer to Figure 8As shown, this embodiment also discloses a sewing method using the sewing template of the above-mentioned shoe upper accessories, comprising the following steps:

[0061] S01, the first plate 31 and the second plate 32 clamp the first accessory and the second accessory, completing the assembly of the clamping assembly 3, and loading the assembled clamping assembly 3 onto the placement position 21 respectively. The first placement position 21 is located at the sewing position below the machine head;

[0062] S02, the sewing machine head moves relative to the workbench, feeds from the head stop position to the starting end of the sewing position, and sews the first accessory and the second accessory at the sewing position according to the preset sewing path;

[0063] S03, when sewing reaches the end of the sewing position, the sewing ends, that is, sewing is performed from point a around the second sewing channel 321, and finally returns to point a; the head of the sewing machine performs a period of idle feeding, so that the head moves to the side of the driving block 22, that is, the head moves from point a to point b; the driving block 22 is pushed to rotate the positioning plate 2, driving the first-order placement position 21 to move away from the sewing position, and the second-order placement position 21 to enter the sewing position, that is, the head contacts each other with the driving block 22 at point b, and moves from point b to point c, and the positioning plate 2 is pushed to rotate by the driving block 22; thereafter, after the head returns to the stop position, S02 is executed, that is, the head returns from point c to point a; and a new round of sewing begins;

[0064] S04 , unloading the sewn clamping assembly 3 , and loading the assembled clamping assembly 3 onto the vacant placement position 21 .

[0065] The movement of the machine head relative to the workbench refers to the relative motion relationship between the two, which may be that the workbench is fixed and the machine head moves, or that the machine head is fixed and the workbench moves.

[0066] The sewing process and the loading and unloading process are carried out simultaneously. At the same time, the clamping assembly 3 is manually loaded and unloaded, and the positioning plate 2 is driven by the sewing machine, reducing the number of manual labor and improving the overall sewing efficiency. Similarly, the external workbench drive base plate 1 can also be driven, so that the driving block 22 and the sewing machine needle abut against each other, and the position of the positioning plate 2 is rotated and adjusted.
