[0025] Combination Figure 1-Figure 7 As shown, the automatic folding device 100 provided by the present invention is mainly used for automatically folding the soft fabric attached to the structural member 200. The structural member 200 can be a component such as an aluminum frame in a leather case keyboard, or any other component, which is not specifically limited in the present invention. In one embodiment of the present invention, the structural member 200 has two side walls 210 and 220 arranged opposite to each other; and a film is provided inside the soft fabric, which can be melted by heating and bonded to the structural member 200. Of course, it is not limited to this, and it can also be an ordinary soft fabric. The automatic folding device 100 in the present invention is suitable for folding all soft fabrics and similar materials.

[0026] Continue to combine Figure 1-Figure 7As shown, the automatic folding device 100 includes a positioning base 110, a pushing mechanism 120 and a pressing block 130. The positioning base 110 is provided with a positioning groove 110a extending along the first direction (X-axis direction), and the positioning groove 110a is used to accommodate the structural member 200 and the soft fabric attached to the two opposite side walls 210 and 220 thereof. Therefore, the positioning groove 110a is arranged corresponding to the structural member 200 to be wrapped with fabric, so that after the structural member 200 attached with the soft fabric is accommodated in the positioning groove 110a, the side walls 210 and 220 of the structural member 200 can abut against the inner wall of the positioning groove 110a. The pushing mechanism 120 and the pressing block 130 are both arranged above the positioning base 110, and the pushing mechanism 120 can reciprocate along the second direction (Y-axis direction). The pushing mechanism 120 is used to push the soft cloth to be slightly bent toward the middle of the positioning groove 110a, and the soft cloth in this state is positioned; the pressing block 130 can be arranged to move up and down in the vertical direction. When the pressing block 130 is pressed down, it can push the slightly bent soft cloth positioned by the pushing mechanism 120 to continue to bend toward the inside of the structural member 200. When the pressing block 130 is pressed down into place, the soft cloth can be pressed to the inner side wall attached to the structural member 200, thereby realizing the folding of the soft cloth.

[0027] Combination Figure 1-Figure 7 As shown, in a preferred embodiment of the present invention, the bottom of the positioning groove 110a is further provided with a slot 110b extending along the first direction (X-axis direction), so that after the structural member 200 attached with the soft cloth is accommodated in the positioning groove 110a, the soft cloth can be extended from the slot 110b. Figure 3 shown.

[0028] Combination Figure 1 , Figure 3 As shown, in one embodiment of the present invention, the positioning base 110 includes a first base 111 and a second base 112 that match each other. The first base 111 and the second base 112 are arranged at intervals and surrounded by the positioning groove 110a, and the gap between the first base 111 and the second base 112 forms the card slot 110b. This structural setting can adjust the spacing between the first base 111 and the second base 112 according to the specific structural member 200, thereby adjusting the width of the positioning groove 110a, so that after the structural member 200 is accommodated in the positioning groove 110a, its side wall can just abut against the inner wall of the positioning groove 110a. Of course, the positioning groove 110a is not limited to this structural setting, and the positioning groove 110a corresponding to the structural member 200 can also be directly opened on the positioning base 110, which does not affect the function of the positioning groove 110a.

[0029] Continue to view Figure 1As shown, in this embodiment, the first base 111 includes a first bottom wall 1111 and a first side wall 1112 disposed on one side of the first bottom wall 1111. Correspondingly, the second base 112 includes a second bottom wall 1121 and a second side wall 1122 disposed on one side of the second bottom wall 1121. The widths of the first bottom wall 1111 and the second bottom wall 1121 may be the same or different. Figure 1 In the embodiment shown, the widths of the two are different; the heights of the first side wall 1112 and the second side wall 1122 are the same. After the first base 111 and the second base 112 are installed, the first bottom wall 1111 and the second bottom wall 1121 are adjacent and spaced apart, and the gap between the two forms the slot 110b, as shown in FIG. Figure 1 As shown. The first side wall 1112 and the second side wall 1122 are located at positions far away from each other, so the first side wall 1112, the first bottom wall 1111, the second bottom wall 1121, and the second side wall 1122 together form the positioning groove 110a. Figure 1 That is, the first side wall 1112 and the second side wall 1122 form the two side walls of the positioning groove 110a, the first bottom wall 1111 and the second bottom wall 1121 together form the bottom of the positioning groove 110a, and the gap between the two forms the card slot 110b located at the bottom of the positioning groove 110a. Figure 3 As shown, after the structure 200 with the soft fabrics A and B attached thereto is accommodated in the positioning groove 110 a , the side walls of the structure 200 and the soft fabrics A and B attached thereto are attached to the first side wall 1112 and the second side wall 1122 .

[0030] See also Figure 1 , Figure 4-7 As shown, in one embodiment of the present invention, the pushing mechanism 120 includes a first pushing block 121 and a second pushing block 122 disposed above the positioning base 110, the first pushing block 121 and the second pushing block 122 are disposed above the first base 111 and the second base 112 respectively and can reciprocate along the second direction (Y-axis direction), wherein the second direction (Y-axis direction) is perpendicular to the first direction (X-axis direction). When the first pushing block 121 and the second pushing block 122 move toward each other, the soft fabrics A and B can be pushed to bend toward the middle of the positioning groove 110a, as shown in FIG. Figure 4 shown.

[0031] In this embodiment, the pushing mechanism 120 further includes a driving member (not shown) connected to the first pushing block 121 and the second pushing block 122 respectively, and the driving member drives the first pushing block 121 and the second pushing block 122 to move toward each other to push the soft fabrics A and B to bend toward the middle of the positioning groove 110a. In a specific embodiment, the driving member is preferably a servo motor, but it is not limited thereto, and of course other driving mechanisms can also be selected.

[0032] Combination Figure 1 , Figure 4 As shown, in a preferred embodiment of the present invention, the opposite sides of the first push block 121 and the second push block 122 form push surfaces 1211 and 1221, and both push surfaces 1211 and 1221 are inclined surfaces, and the two push surfaces 1211 and 1221 gradually approach each other from the top to the bottom. In this way, after the first push block 121 and the second push block 122 move toward each other and push the soft fabrics A and B to bend toward the middle, the pressing block 130 can move downward along the push surfaces 1211 and 1221 during the pressing process. On the one hand, the push surfaces 1211 and 1221 can be pushed to move the first push block 121 and the second push block 122 away from each other, and on the other hand, the guiding effect of the inclined surface facilitates the inward bending of the soft fabrics A and B during the pressing.

[0033] Continue to combine Figure 1-Figure 7 As shown, in the present invention, the pressing block 130 includes a pressing block 131 which is movably arranged above the positioning base 110 and connected to the driving member. The lower end of the pressing block 130 is provided with a pressing block 131, which extends along the first direction (X-axis direction), and the pressing block 131 is arranged corresponding to the interior of the structural member 200, so that the pressing block 131 can be pressed into the interior of the structural member 200 and can be detached. Therefore, when the driving member drives the pressing block 131 to press down, the bent soft fabrics A and B can be pushed to continue to bend toward the interior of the structural member 200. When the pressing block 131 is pressed down to the bottom of the structural member 200, the soft fabrics A and B are bent and attached to the inner wall of the structural member 200 to achieve folding. The driving member is not specifically limited in the present invention, as long as it can drive the pressing block 130 to move up and down.

[0034] Combination Figure 1 , Figure 6 As shown, in a preferred embodiment of the present invention, the two side surfaces of the extrusion block 131 in the second direction (Y-axis direction) are provided with step-shaped pressing surfaces 131a (see Figure 1 ), when the extrusion block 131 is pressed down to the bottom of the structural member 200, the pressing surface 131a is pressed against the top of the side walls 210 and 220 of the structural member 200. At this time, the extrusion block 131 cooperates with the inner wall of the positioning groove 110a to clamp and squeeze the side walls 210 and 220 of the structural member 200 and the soft fabrics A and B attached to the outside (see Figure 6 ), so that the soft fabrics A and B wrap the side walls 210 and 220 of the structural member 200 and adhere thereto.

[0035] Combination Figure 1 , Figure 4 , Figure 6As shown, the extrusion block 131 includes a first extrusion section 1311 and a second extrusion section 1312. The second extrusion section 1312 is convexly arranged at the end of the first extrusion section 1311 and extends along the first direction (X-axis direction). The width of the second extrusion section 1312 in the second direction (Y-axis direction) is smaller than the width of the first extrusion section 1311. Therefore, the convex end surface of the first extrusion section 1311 in the second direction (Y-axis direction) forms the pressing surface 131a (see Figure 1 ). At the same time, the height of the second extrusion section 1312 preferably corresponds to the height of the two side walls 210, 220 of the structural member 200. In this way, when the second extrusion section 1312 is pressed down to the bottom of the structural member 200, the second extrusion section 1312 is just accommodated in the interior of the structural member 200, and the pressing surface 131a is pressed against the top of the side walls 210, 220 of the structural member 200. The second extrusion section 1312 cooperates with the inner wall of the positioning groove 110a to extrude the side walls 210, 220 of the structural member 200 and the soft fabrics A, B attached to the outside, so that the soft fabrics A, B fit the inner and outer sides of the side walls 210, 220 of the structural member 200 (see Figure 6 ).

[0036] Continue to view Figure 1 As shown, the cross section of the first extrusion section 1311 is a wedge-shaped structure, and the two side surfaces 131b of the first extrusion section 1311 in the second direction (Y-axis direction) are inclined, and the two side surfaces 131b of the first extrusion section 1311 in the second direction (Y-axis direction) gradually approach the end where the second extrusion section 1312 is located. At the same time, the cross section of the second extrusion section 1312 is a rectangular structure. With this structural arrangement, when the extrusion block 131 is pressed down, the inclined two side surfaces 131b of the first extrusion section 1311 match the push surfaces 1211 and 1221 of the first push block 121 and the second push block 122, and the first push block 121 and the second push block 122 are pushed to move in opposite directions by the action of the inclined surfaces, so that the first push block 121 and the second push block 122 are automatically retracted. When pressed into place, the side surface of the second extrusion section 1312 can be pressed against the inner wall surface of the structural member 200 , thereby squeezing the soft fabrics A and B to make them adhere to the inner wall of the structural member 200 .

[0037] Continue to combine Figure 1 , Figure 4-7 As shown, in one embodiment of the present invention, the pressing block 130 also includes a fixed block 132, and the fixed block 132 is connected to the upper end of the extrusion block 131 and connected to the driving member. The width of the fixed block 132 in the second direction (Y-axis direction) is greater than the width of the extrusion block 131. Of course, it is not limited to such a structural setting.

[0038] Combination Figure 4-6As shown, in a preferred embodiment of the present invention, at least the extrusion block 131 on the pressing block 130 is a heatable structure, and preferably the entire pressing block 130 is a heatable structure. When the pressing block 130 is pressed down to achieve the folding, the heat of the pressing block 130 activates the adhesive film inside the soft fabrics A and B, causing the adhesive film to melt and be fixed to the structural member 200.

[0039] Combine again below Figure 1-Figure 7 As shown, the working principle and process of the automatic folding device 100 of the present invention are explained.

[0040] First, two soft fabrics A and B are attached to the outer sides of the two side walls 210 and 220 of the structural member 200 using a device. Figure 2 In the manner shown, the soft fabric A is attached to the outside of the side wall 210 of the structural member 200, and the soft fabric B is attached to the outside of the side wall 220 of the structural member 200, but the present invention is not limited thereto, and the soft fabrics A and B wrap the entire exterior of the structural member 200, and the excess parts are attached and extended downward. At the same time, the upper ends of the soft fabrics A and B protrude from the upper ends of the two side walls 210, 220 of the structural member 200, as shown in FIG. Figure 2 shown.

[0041] Next, the structural member 200 with the soft fabrics A and B attached thereto is placed as a whole in the positioning groove 110a of the positioning base 110. At this time, the two side walls 210 and 220 of the structural member 200 abut against the two inner walls of the positioning groove 110a, so that the soft fabrics A and B are respectively clamped between the side walls 210 and 220 of the structural member 200 and the inner walls of the positioning groove 110a. At the same time, the upper ends of the soft fabrics A and B protrude from the upper ends of the two inner walls of the positioning groove 110a. Figure 3 shown.

[0042] Then, the servo motors on both sides drive the first push block 121 and the second push block 122 to move toward each other along the second direction (Y-axis direction), so that the first push block 121 and the second push block 122 push the soft fabrics A and B to bend toward the middle of the structural member 200, so that the top of the soft fabrics A and B is located above the inner cavity of the structural member 200, as shown in FIG. Figure 4 At this time, the servo motor stops running to stop the first push block 121 and the second push block 122 at this position, so as to realize the positioning of the soft fabrics A and B.

[0043] Next, the driving member drives the pressing block 130 to move downward, and the pressing block 130 moves downward so that its squeezing block 131 presses against the soft fabrics A and B. Figure 5As shown, the soft fabrics A and B are slightly pushed down, and the side surface 131b of the squeezing block 131 pushes the pushing surfaces 1211 and 1221 of the first push block 121 and the second push block 122, so that the first push block 121 and the second push block 122 move away from each other, and the first push block 121 and the second push block 122 automatically retract after receiving the force. During the squeezing block 131 pressing down, the soft fabrics A and B are pushed to continue to bend toward the inside of the structural member 200; as the squeezing block 131 moves down, the soft fabrics A and B gradually bend and fit toward the inner wall of the structural member 200; when the driving squeezing block 130 moves down until the squeezing block 131 is pressed down to the position, the squeezing block 131 is pressed against the inside of the structural member 200. During this process, the squeezing block 131 squeezes the soft fabrics A and B toward both sides to make them fit against the inner wall of the structural member 200, thereby completing the folding.

[0044] Furthermore, by heating the pressing block 130, the pressing block 130 self-heats and activates the adhesive film inside the fabric, causing the adhesive film to melt and adhere to the structural member 200, thereby fixing the soft fabrics A and B to the structural member 200, thereby wrapping the entire structural member 200, and then taking out the product to complete the entire folding operation.

[0045] In summary, the automatic folding device 100 of the present invention is provided with a positioning base 110 and a positioning groove 110a thereon to accommodate the structural member 200 and the soft fabrics A and B attached to the two opposite side walls 210 and 220 thereof, and a pushing mechanism 120 and a pressing block 130 are provided above the positioning base 110. The pushing mechanism 120 includes a first pushing block 121 and a second pushing block 122 that can reciprocate along the second direction (Y-axis direction), and the pressing block 130 can move along the vertical direction. The pressing block 130 is provided with an extrusion block 131 extending along the first direction (X-axis direction), and the extrusion block 131 can be pressed into the structural member 200 and can Therefore, when folding, the structural member 200 and the soft fabrics A and B attached to the two side walls thereof are placed as a whole in the positioning groove 110a, and then the first push block 121 and the second push block 122 move toward each other in the second direction (Y-axis direction) to push the soft fabrics A and B to bend toward the middle of the positioning groove 110a, and then the pressing block 130 is driven to press down to push the bent soft fabrics A and B to continue to bend toward the inside of the structural member 200. When the squeezing block 131 is pressed down to the bottom of the structural member 200, it squeezes the soft fabrics A and B to fit the inner wall of the structural member 200, thereby realizing the wrapping and folding of the soft fabrics A and B. Compared with the manual folding method of fabric in the prior art, the folding method of the present invention can firstly ensure the line consistency of the folding position, thereby solving the problem of uneven edges in the prior art, improving product consistency and operation stability, and ensuring the folding quality of the leather cover keyboard; secondly, the operation time of a single product is optimized from the existing 120s to 30s, thereby improving the folding efficiency and the overall production capacity.

[0046] The structures of other parts of the automatic folding device 100 involved in the present invention are conventional structures well known to ordinary technicians in the field, and will not be described in detail here.

[0047] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
