[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Figures 1 to 5 In the invention, a semi-automatic jig for patching cloth on the surface of the front shell of an audio system is provided, comprising an electrical control box 10. A base plate 51 is provided at the top of the electrical control box 10. The top ends of the base plate 51 are fixedly connected to a cloth clamping cylinder mounting plate 52 by a pushing cylinder 50, and a control button 11 is provided on one side in the length direction. The two ends of the cloth clamping cylinder mounting plate 52 are fixedly connected to a first cloth clamping cylinder 70, and multiple groups of second cloth clamping cylinders 60 are fixedly connected on both sides. The two ends of the cloth clamping cylinder mounting plate 52 are located at the top of the guide rod and are respectively provided with a first connecting strip 702 and a second connecting strip 701. The cloth clamping cylinder mounting plate 52 is provided with an adjustment hole 705. The adjustment hole 705 facilitates the left and right adjustment of the first cloth clamping cylinder 70. A stretching cylinder 65 is installed between each set of second cloth-clamping cylinders 60. A support cylinder 80 is fixedly connected to the bottom end of the cloth-clamping cylinder mounting plate 52. Two downward-pressing cylinders 30 are mounted on the top of the electrical control box 10 via guide rods and a fixing plate 20. The bottom end of the downward-pressing cylinder 30 is fixedly connected to a heated upper pressing die 32. A product carrier 81 is located in the middle of the cloth-clamping cylinder mounting plate 52. The top of the product carrier 81 places the front housing product 100, and the heated upper pressing die 32 presses the patch 101 onto the top of the product 100. Two handles 12 are provided at each end of the electrical control box 10, and three heat dissipation vents 13 are provided on the upper side of the handles 12. A grating 15 is installed at each end of the top of the electrical control box 10, and a barrier 19 is provided on the top. The grating 15 is located near the control button 11, which is a two-handed button. The use of the grating also improves safety. A heating source is provided inside the heated upper pressing die 32 to heat-press the patch onto the top of the front housing of the speaker.

[0024] An upper pressing plate 31 is mounted on the top of the electrical control box 10 . The top of the upper pressing plate 31 is fixedly connected to the lower pressing cylinder 30 , and a heating upper pressing mold 32 is provided on the lower side. The surface of the heating upper pressing mold 32 is provided with a layer of silicone.

[0025] One end of the two second cloth clamping cylinders 60 is fixedly connected to a cloth clamping claw 61, which is arranged on the upper and lower sides of the patch 101. The cloth clamping claw 61 clamps the two sides of the cloth piece. The stretching cylinder 65 stretches the two sides of the cloth piece.

[0026] A support plate 71 is provided at the top of the first cloth clamping cylinder 70, and the top of the support plate 71 is slidably connected to a movable plate 74. One end of the movable plate 74 is movably connected to a movable claw 75 via a pin 751. The side wall of the first cloth clamping cylinder 70 is fixedly connected to a fixed claw 76, and the movable claw 75 is pressed against the fixed claw 76. A guide rail 72 is provided at the top of the support plate 71, and the bottom end of the movable plate 74 is fixedly connected to a slider 73, and the slider 73 is slidably connected to the guide rail 72. The fixed claw 76 and the movable claw 75 clamp the two ends of the patch. The slider 73 moves to drive the movable claw 75 to press against the fixed claw 76, thereby pressing the cloth piece. The first cloth clamping cylinder 70 moves downward to fit the cloth piece to the upper surface of the front shell product 100 of the audio system.

[0027] The product support fixture 81 has an annular groove 813 at its center. It also has an arcuate surface 811 at each end and a stepped groove 812 around its perimeter. Connecting holes 810 are located around the annular groove 813, which are fixedly connected to the top of the support cylinder 80. A fabric support 85 is crimped onto the perimeter of the product support fixture 81.

[0028] First, place the product on the product carrying jig, and then cover the product with a piece of cloth. At this time, all four edges of the cloth are flat on the cloth clamping claws, and then start the control button. The cloth clamping claws are extended through the cloth clamping cylinder to close the cloth clamping claws and clamp the cloth. At this time, the stretching cylinders on all sides move outward at the same time to achieve a taut state of the cloth. Then the pushing cylinder installed on the mounting plate of the cloth clamping cylinder will move downward to make the cloth close to the product. At this time, the pressing cylinder will press down and press the cloth tightly against the product through the heated upper die (silicone-plated surface). After a period of temperature pressing, the cloth is tightly attached to the product. The pressing is completed, the jig automatically resets, and the operation is repeated.

[0029] The above are only specific application examples of the present invention and do not constitute any limitation on the scope of protection of the present invention. Any technical solution formed by equivalent transformation or equivalent replacement shall fall within the scope of protection of the present invention.
