[0042] The terms "first" and "second" used in the terminology of this invention are for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as limiting the order of events.

[0043] The present invention provides an assembly fixture system for a horn cover covered with fabric. The horn cover 196 has an elliptical hole 197 in the middle position. The assembly fixture system includes a first fixture 16 for applying glue to the horn cover 196, a second fixture 15 for spraying glue on the horn cover 196, a third fixture for pressing the fabric on the horn cover 196, a fourth fixture for laser cutting off waste material, a fifth fixture for pushing the edge material of the horn cover 196, a sixth fixture for pushing the edges of both sides of the elliptical hole 197 of the horn cover 196, and a seventh fixture for pushing the edges of both ends of the elliptical hole 197 of the horn cover 196. The horn cover 196 is completely assembled by passing through the first fixture 16, the second fixture 15, the third fixture, the fourth fixture, the fifth fixture, the sixth fixture, and the seventh fixture in sequence. The sixth fixture includes a first base 11 and a first extrusion cone 12 located above the first base 11. The first base 11 includes a first fixing frame 112, a first placement plate 111 mounted on the first fixing frame 112 for placing the horn cover 196, and a first moving component mounted inside the first fixing frame 112 for extending into the elliptical hole 197. The first placement plate 111 is provided with a first through hole 1111 for the first moving component to extend into. The first extrusion cone 12 moves downward to move the first moving component to both sides of the elliptical hole 197. The seventh fixture includes a second base 13 and a second extrusion cone 14 located above the second base 13. The second base 13 includes a second fixing frame 132, a second placement plate 131 mounted on the second fixing frame 132 for placing the horn cover 196, and a second moving component mounted inside the second fixing frame 132 for extending into the elliptical hole 197. The second placement plate 131 is provided with a second through hole for the second moving component to extend into. The second extrusion cone 14 moves downward to move the second moving component towards both ends of the elliptical hole 197.

[0044] When covering the horn cover 196 with fabric, firstly, the outer surface of the horn cover 196 is placed inside the first fixture 16, and adhesive is applied to the inner side of the horn cover 196 and the periphery of the oval hole 197. After applying adhesive, the horn cover 196 is placed on the second fixture 15 with the inner side of the horn cover 196 facing down. Adhesive is then sprayed onto the outer surface of the horn cover 196. After spraying adhesive onto the outer surface of the horn cover 196, it is placed on the third fixture, and the fabric 199 is placed on the third fixture. The third fixture presses the fabric 199 together, fixing the fabric 199 to the horn. On cover 196, the horn cover 196, with the fabric 199 fixed in place, is placed on the fourth fixture. A laser cuts away the waste material from the edges of the horn cover 196 and the oval hole 197 on the fourth fixture. The horn cover 196 with the waste material removed is then placed on the fifth fixture. The fifth fixture pushes the fabric 199 after the fabric 196 has been cut, fixing the fabric 199 to the glue inside the horn cover 196, so that the fabric 199 wraps around the edges of the horn cover 196. The horn cover 196 with the fabric 199 pushed to the edge is then placed on the sixth fixture. The first moving component of the sixth fixture extends into the elliptical hole 197 of the horn cover 196. Simultaneously, the fabric 199 surrounding the elliptical hole 197 extends inward into the elliptical hole 197. The first extrusion cone 12 moves downward and extrudes the first moving component, causing it to move to both sides of the elliptical hole 197, thus fixing the fabric 199 on both sides of the elliptical hole 197. Finally, the horn cover 196 is placed on the seventh fixture, and the second moving component on the seventh fixture extends... The fabric 199 at both ends of the elliptical hole 197 is pushed into the inner side of the elliptical hole 197. The second extrusion cone 14 moves down and extrudes the second moving component, causing the second moving component to move towards both ends of the elliptical hole 197 and fix the fabric 199 at both ends of the elliptical hole 197, thereby completing the fabric wrapping of the horn cover 196. Through the above operation, manual operation is greatly reduced. While reducing manual operation, the efficiency of fabric wrapping of the horn cover 196 can also be effectively improved, thus effectively increasing the production capacity of fabric wrapping of the horn cover 196.

[0045] Please refer to Figure 5 , Figure 6 , Figure 10 and Figure 11 , Figure 5 This is a perspective view of the second fixture in the assembly fixture system for the horn cover covering of the present invention. Figure 6 This is a perspective view of the first fixture of the assembly fixture system for the horn cover covering of the present invention.

The bottom wall of the first placement groove 161 is provided with a first arc-shaped structure that matches the outer surface of the horn cover 196. The first placement groove 161 is used to place the horn cover 196, and the first arc-shaped structure is used to fit the outer surface of the horn cover 196 to prevent the horn cover 196 from shaking in the first anti-shake groove, which facilitates the application of glue to the inner side of the horn cover 196 and the inner side of the elliptical hole 197.

[0046] The second fixture 15 is provided with a first fixing groove 151 for placing the edge of the horn cover 196. The edge of the horn cover 196 is located in the first fixing groove 151. The first fixing groove 151 is used to place the edge of the horn cover 196 to prevent the horn cover 196 from shaking in the second fixture 15, thereby facilitating the application of adhesive to the outer surface of the horn cover 196.

[0047] The third fixture includes a third base 181 and a first pressure plate 182. The third base 181 has a second fixing groove 1811 for placing a horn cover 196. The first pressure plate 182 has a second placement groove 1821 that matches the outer surface of the horn cover 196. The second fixing groove 1811 of the third base 181 is used to place the horn cover 196, with the edge of the horn cover 196 located within the second placement groove 1821. The horn cover 196 is placed within the third base 181 and can sway within it. The first pressure plate 182 is used to squeeze... Press the fabric 199 to fix the fabric 199 to the outer surface of the speaker cover 196. When pressing and fixing the fabric 199, place the fabric 199 on the outer surface that has been sprayed with glue. The first pressure plate 182 moves down and presses the fabric 199. Since the second placement groove 1821 of the first pressure plate 182 matches the outer surface of the speaker cover 196, when the first pressure plate 182 presses down, the fabric 199 is fixed to the outer surface of the speaker cover 196 by the glue after spraying, thereby completing the covering of the outer surface of the speaker cover 196 with fabric. Please refer to Figure 12 , Figure 12 This is an exploded view of the fourth fixture of the assembly fixture system for the horn cover covering fabric of the present invention. The fourth fixture includes a fourth base 191 and a cover body 192 for covering the horn cover 196.

The fourth moving components 173 are used to move the fabric 199 at both ends of the horn cover 196 toward the inside of the horn cover 196. The second pressure plate 171 is used to fix the fabric 199 on both sides and both ends of the horn cover 196 onto the horn cover 196, thereby covering the edge of the horn cover 196.

[0049] Please refer to Figure 9 , Figure 9 This is a perspective view of the first push plate of the assembly fixture system for the speaker cover covering of the present invention. The third moving component 172 includes a plurality of first cylinders 1721 respectively disposed on both sides of the fifth base 17 and first push plates 1722 symmetrically disposed on both sides of the fifth base 17 and connected to the first cylinders 1721. The first push plate 1722 is provided with a first positioning groove 1723 abutting against the fifth base 17 on the side closer to the fifth base 17. The first cylinders 1721 are installed on both sides of the fifth base 17, and the first push plates 1722 are installed on the first cylinders 1721. The first cylinders 1721 are used to drive the first push plates 1722 to move, so that the first push plates 1722 push the fabric 199 on both sides of the speaker cover 196 to move inward to the inside of the speaker cover 196, thereby facilitating the second pressure plate 171 to press down, so that the fabric 199 wraps the edges of both sides of the speaker cover 196.

[0050] The fourth moving component 173 includes second cylinders 1731 symmetrically arranged at both ends of the fifth base 17 and second push plates 1732 respectively arranged on the symmetrical second cylinders 1731. The second push plate 1732 is provided with a second positioning groove abutting against the fifth base 17 on the side closer to the fifth base 17. The second cylinders 1731 are installed at both ends of the fifth base 17, and the second push plates 1732 are installed on the second cylinders 1731. The second cylinders 1731 are used to drive the second push plates 1732 to move, so that the second push plates 1732 push the fabric 199 at both ends of the horn cover 196 to move inward to the inside of the horn cover 196, thereby facilitating the second pressure plate 171 to press down, so that the fabric 199 wraps around the edges of both ends of the horn cover 196.

[0051] Please refer to Figure 2 , Figure 2 This is an exploded view of the first base of the assembly fixture system for the speaker cap covering of the present invention. The first moving component includes a first mounting base 113 fixed on the first base 11, a third cylinder 114 symmetrically arranged on the first mounting base 113, a first pressing block 115, which is elongated and mounted on the third cylinder 114, and a first heating element disposed on the first pressing block 115. The third cylinder 114 is used to drive the first pressing block 115 to move relative to each other along the two sides of the elliptical hole 197. The outer side of the first pressing block 115 has a second arc-shaped structure that matches the elliptical hole 197. The first mounting base 113 is used to fix the symmetrical third cylinder 114. The first pressing block 115 is used to extend into the elliptical hole 197 of the speaker cap 196. The first heating element is used to heat the first pressure plate 182. After the first pressure plate 182 contacts the side wall of the elliptical hole 197, it melts the glue from the cured state. When fixing the fabric 199 on both sides of the elliptical hole 197 of the horn cover 196, firstly, the horn cover 196 is placed on the fifth base 17. When the horn cover 196 is placed on the fifth base 17, the symmetrical first pressing block 115 extends into the elliptical hole 197 of the horn cover 196. At the same time as the first pressing block 115 extends into the elliptical hole 197, the fabric 199 located on the outer surface of the elliptical hole 197 is pushed into the elliptical hole 197. At the same time, the first extrusion cone 12 presses down, causing the symmetrical first pressing block 115 to move towards both sides of the elliptical hole 197. Meanwhile, since the first heating element is installed on the first pressing block 115, when the first pressing block 115 contacts the side wall of the elliptical hole 197, the first pressing block 115 melts the glue on both sides of the elliptical hole 197, making it easier for the fabric 199 to adhere to the side wall of the elliptical hole 197, so as to complete the wrapping of the edges of the elliptical hole 197.

[0052] Please refer to Figure 4 , Figure 4This is a perspective view of the second base of the assembly fixture system for the speaker cover covering of the present invention. The second moving component includes a second mounting base 133 fixed on the second base 13, a fourth cylinder 134 symmetrically arranged on the second mounting base 133, a second pressure block 135, which is elongated and respectively mounted on the fourth cylinder 134, and a second heating element disposed on the second pressure block 135. The fourth cylinder 134 is used to drive the second pressure block 135 to move relative to each other along the two ends of the elliptical hole 197. The outer side of the second pressure block 135 is a third arc-shaped structure that matches the elliptical hole 197. The second mounting base 133 is used to fix the symmetrical fourth cylinder 134. The second pressure block 135 is used to extend into the elliptical hole 197 of the speaker cover 196. The first heating element is used to heat the second pressure plate 171. After the second pressure plate 171 contacts the side wall of the elliptical hole 197, the adhesive melts from the cured state. When fixing the fabric 199 on both sides of the elliptical hole 197 of the horn cover 196, the horn cover 196 is placed on the sixth base 193. When the horn cover 196 is placed on the sixth base 193, the symmetrical second pressing block 135 extends into the elliptical hole 197 of the horn cover 196. At the same time as the second pressing block 135 extends in, the fabric 199 on the outer surface of the elliptical hole 197 is pushed into the elliptical hole 197. At the same time, the second extrusion cone 14 presses down, causing the symmetrical second pressing block 135 to move towards both ends of the elliptical hole 197. Meanwhile, since the second heating element is installed on the second pressing block 135, when the second pressing block 135 contacts the side wall of the elliptical hole 197, the second pressing block 135 melts the glue at both ends of the elliptical hole 197, making it easier for the fabric 199 to adhere to the side wall of the elliptical hole 197, so as to complete the wrapping of the edges of both ends of the elliptical hole 197 with fabric.

[0053] In this embodiment, a fourth through hole is provided at the position opposite to the elliptical hole 197 on the fourth base 191, and a fifth through hole 1921 is provided at the position opposite to the fourth through hole on the cover 192. The fourth through hole is used to expose the fabric 199 in the elliptical hole 197, so as to facilitate laser cutting. The fifth through hole 1921 on the cover 192 is used to limit the laser cutting of the fabric 199 in the fourth through hole, so as to avoid the problem that too much fabric 199 is cut by the laser and the fabric 199 cannot cover the elliptical hole 197.

[0054] In this embodiment, both the first pressure plate 182 and the second pressure plate 171 are provided with a third heating element. Both the first pressure plate 182 and the second pressure plate 171 are made of heat-conducting material. The third heating element heats the first pressure plate 182. When the first pressure plate 182 presses the fabric 199, it simultaneously melts the glue on the speaker cover 196, making it easier for the glue on the speaker cover 196 to fix the fabric 199. Furthermore, the third heating element heats the second pressure plate 171. When the second pressure plate 171 presses the speaker cover 196, the second pressure plate 171 melts the glue on the inside of the speaker cover 196, making it easier for the glue on the inside of the speaker cover 196 to adhere the fabric 199, thereby completing the edge binding of the speaker cover 196.

[0055] Please refer to Figure 13 , Figure 13 This is an exploded view of the eighth fixture of the assembly fixture system for the horn cover covering of the present invention. The assembly fixture system also includes an eighth fixture for pressing light guides. The inner side of the horn cover 196 is provided with a mounting groove for mounting light guides and a light-transmitting hole 198 located in the mounting groove. The eighth fixture includes a sixth base 193, a third placement plate 194 mounted on the sixth base 193, and a pressing block 195 located above the sixth base 193. A fourth heating element is provided on the pressing block 195. The eighth fixture is used to install light guides on the horn cover 196. The sixth base 193 is used to install the third placement plate 194. The third placement plate 194 is used to place the horn cover 196, and the pressing block 195 is used to press and fix the light guides in the light-transmitting hole 198.

[0056] In this embodiment, the third placement plate 194 is also provided with a fixing protrusion that extends into the elliptical hole 197. The fixing protrusion is used to limit the horn cover 196. When the fixing protrusion extends into the elliptical hole 197, the pressing block 195 can prevent the horn cover 196 from tilting upwards during the processing.

[0057] In this embodiment, the improved part of the present invention is a complete fixture system for achieving the 196-layer fabric covering of the horn cover, while the laser cutting of waste, dispensing technology, and spraying technology are all existing technologies.

[0058] Please refer to Figure 17 , Figure 17 The diagram illustrates the steps of assembling the horn cover fabric according to the present invention. The horn cover fabric assembly method, based on an assembly fixture system for the horn cover 196, includes the following steps: Step 1: Apply adhesive S101 to the speaker cover using the first fixture; Step 2: Apply adhesive S102 to the horn cover after it has been glued using the second fixture; Step 3: Press the horn cover after spraying glue onto the fabric using the third fixture (S103). Step 4: Use the fourth fixture to laser-cut the waste material S104 from the pressed fabric cover; Step 5: The horn cover after laser-cut waste is pushed to the edge using the fifth fixture (S105). Step 6; Using the sixth fixture, the flared cover with the flared edge treatment is subjected to flared edge treatment on both sides of the oval hole S106. Step 7: Using the seventh fixture, the flared cap with the elliptical hole on both sides is further edged at both ends of the elliptical hole (S107).

[0059] When wrapping the horn cover 196 with fabric, firstly, the horn cover 196 is placed in the first fixture 16 to apply adhesive to the inside of the horn cover 196. The horn cover 196 is then dried to complete the adhesive application process. After drying, the horn cover 196 is flipped over and placed on the second fixture 15 with its outer surface facing upwards to facilitate the spraying of adhesive onto its outer surface. The horn cover 196 is then dried after spraying the adhesive to complete the adhesive application process. Finally, the dried horn cover 196 is placed in the third fixture. On the third fixture, the first pressure plate 182 squeezes the fabric 199. The first pressure plate 182 heats the glue to melt the glue and adhere the fabric 199, thereby pressing the fabric of the speaker cover 196. The pressed speaker cover 196 is placed on the fourth fixture, and the cover body 192 of the fourth fixture covers the speaker cover 196. The laser cuts off the excess fabric 199 around the speaker cover 196 and the fabric 199 inside the oval hole 197, thereby removing the waste from the speaker cover 196. The speaker cover 196 after removing the waste is flipped over and placed on the fifth fixture. The fifth fixture's first... The third moving component 172 pushes the fabric 199 on both sides of the horn cover 196 toward the inside of the horn cover 196. The fourth moving component 173 pushes the fabric 199 at both ends of the horn toward the inside of the horn cover 196. The second pressure plate 171 presses down, fixing the fabric 199 on both sides and both ends of the horn cover 196 to the inside of the horn cover 196, thereby achieving the edge-pushing treatment of the horn cover 196. The edge-pushed horn cover 196 is placed on the sixth fixture. The first moving component of the sixth fixture extends into the elliptical hole 197. At the same time, the first extrusion cone 12 moves down to extrude the first moving component, causing the first... The moving component moves to both sides of the elliptical hole 197, fixing the fabric 199 on both sides of the elliptical hole 197 to achieve the edge pushing treatment on both sides of the elliptical hole 197. The horn cover 196 with the edge pushing treatment on both sides of the elliptical hole 197 is placed on the seventh fixture. The second moving component extends into the elliptical hole 197. When the second extrusion cone 14 moves down, the second moving component moves to both ends of the elliptical hole 197, fixing the fabric 199 at both ends of the elliptical hole 197 to both ends of the elliptical hole 197, thereby completing the fabric wrapping of the horn cover 196.

[0060] Working principle: When wrapping the horn cover 196 with fabric, firstly, the outer surface of the horn cover 196 is placed in the first placement groove 161 of the first fixture 16. The first placement groove 161 fits against the outer surface of the horn cover 196, thereby limiting the horn cover 196 and preventing it from shaking. This facilitates the application of adhesive to the inner edge of the horn cover 196. After the adhesive application to the inner edge of the horn cover 196 is completed, the horn cover 196 is removed and dried. The dried horn cover 196 is then flipped over and placed in the first fixing groove 151 of the second fixture 15, with the outer surface of the horn cover 196 facing upwards, facilitating the spraying of adhesive onto the outer surface of the horn cover 196. The horn cover 196, after being sprayed with adhesive, is then dried and placed in the third fixture. In the fixture, the second fixing groove 1811 of the third fixture limits the horn cover 196, and the fabric 199 is placed on the horn cover 196. At the same time, the first pressure plate 182 moves down and squeezes the fabric 199 to fit against the horn cover 196. Since the second placement groove 1821 is in contact with the outer surface of the horn cover 196, the first pressure plate 182 can fit perfectly against the outer surface of the horn cover 196. Due to the action of the third heating element, the third heating element heats the first pressure plate 182. During the process of the first pressure plate 182 squeezing the fabric 199, the heat of the first pressure plate 182 melts the glue on the outer surface of the horn cover 196, so that the fabric 199 adheres to the glue, thereby completing the pressing process of the horn cover 196.

[0061] After the fabric pressing process of the horn cover 196 is completed, the horn cover 196 is placed on the platform 1911 of the fourth base 191. At the same time, the cover body 192 is placed over the horn cover 196. The cover body 192 is used to reserve the fabric 199 for edging the horn cover 196. The fifth through hole 1921 of the cover body 192 exposes the fabric 199 of the oval hole 197. The cover body 192 also reserves the fabric 199 for edging the oval hole 197. After the cover body 192 is in place, the external laser equipment laser-cuts the excess fabric 199 on the horn cover 196. The horn cover 196 after the fabric 199 is cut off is flipped over and placed on the fifth base 17. Simultaneously, the first cylinder 1721 drives the first push plate 1722 to move towards the inside of the horn cover 196, so as to wrap the edges of the horn cover 196 with the pre-reserved fabric 199 on both sides of the horn cover 196. The second cylinder 1731 drives the second push plate 1732 to push towards the inside of the horn cover 196, so as to wrap the edges of the horn with the pre-reserved fabric 199 at both ends of the horn cover 196. Since the second pressure plate 171 is heated by the third heating element, when the second pressure plate 171 is pressed down, the second pressure plate 171 melts the glue on the inside of the horn cover 196 and makes the fabric 199 adhere to the inside of the horn cover 196, so as to complete the wrapping treatment of the edges of the horn cover 196.

[0062] After the fabric wrapping around the edge of the horn cover 196 is completed, the horn cover 196 is placed on the first placement plate 111 of the sixth fixture. Simultaneously, the first pressing block 115 of the first moving assembly pushes the fabric 199 inside the elliptical hole 197 towards the inside of the horn cover 196. After the first pressing plate 182 moves to the set position, the first extrusion cone 12 moves downwards, moving between the symmetrical first pressing plates 182 and pressing them together, causing the symmetrical first pressing plates 182 to... The first pressure plate 182 moves to both sides of the elliptical hole 197. Because the first heating element heats the first pressure plate 182, when the first pressure plate 182 is in contact with the side wall of the elliptical hole 197, the first pressure plate 182 melts the glue on the side wall of the elliptical hole 197, causing the fabric 199 on both sides of the elliptical hole 197 to adhere to both sides, thus completing the edge binding treatment on both sides of the elliptical hole 197. Further, the horn cover 196 is placed in the second placement slot 18 of the seventh fixture. Inside 21, the second pressure plate 171 of the second moving assembly pushes the fabric 199 at both ends of the elliptical hole 197 into the interior of the elliptical hole 197. Simultaneously, the second extrusion cone 14 descends and presses the symmetrical second pressure plate 171. The symmetrical second pressure plates 171 move towards both ends of the elliptical hole 197. Due to the action of the second heating element, when the second pressure plate 171 contacts the sidewalls at both ends of the elliptical hole 197, the second pressure plate 171 melts the glue on the sidewalls at both ends of the elliptical hole 197, allowing the fabric to... 199 is adhered to the sidewalls at both ends of the elliptical hole 197. Finally, the horn cover 196 is placed on the third placement plate 194 of the sixth base 193. At the same time, the light guide is placed in the light-transmitting hole 198. The extrusion block 195 moves down and extrudes the light guide. Due to the action of the fourth heating element, the extrusion block 195 causes the light-transmitting element to fuse and fix with the sidewall of the light-transmitting hole 198 during the extrusion process, so as to fix the light-transmitting element on the horn cover 196, thereby completing the assembly of the horn cover 196 covered with cloth and the light guide.

[0063] The preferred embodiment of the horn cover fabric assembly fixture system and assembly method involves applying adhesive to the inside of the horn cover using a first fixture, placing the adhesive-coated horn cover on a second fixture to spray adhesive onto the outer surface of the horn cover, placing the sprayed adhesive horn cover on a third fixture to press the fabric, placing the pressed horn cover on a fourth fixture to remove excess waste material, placing the horn cover with the removed waste material on a fifth fixture to edge the horn cover, placing the edge-bound horn cover on a sixth fixture to edge the sides of the elliptical hole, and finally placing the horn cover on a seventh fixture to edge the ends of the elliptical hole. This greatly reduces manual operation and effectively improves the efficiency of horn cover fabric assembly.

[0064] 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.
