[0002] Fabric often needs to be folded during the sewing process. In the current technology, the folding process of fabric mainly relies on manual operation. Specifically, workers place the fabric on a special folding template to fold it, and then sew the folded pieces together.

[0003] However, manual operation is inefficient and prone to errors, making it difficult to guarantee folding accuracy and consistency, thus affecting overall production efficiency and quality. Furthermore, the fabric often contains chemical fumes, which can be harmful to workers' health if inhaled over a long period. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic folding device for an intelligent sewing workstation includes a mounting base, a worktable fixedly mounted on the mounting base, a folding working surface on the upper surface of the worktable, a folding plate on the upper side of the folding working surface, a rotary motor fixedly mounted on the left side of the worktable via a fixed seat, the output shaft of the rotary motor being drivenly connected to a rotary shaft, and a driven shaft rotatably connected to the right side of the folding working surface via a bearing, the axis of the driven shaft coinciding with the axis of the rotary shaft, and both the rotary shaft and the driven shaft being fixedly connected to one side of the folding plate.

[0007] An installation plate is vertically installed inside the workbench. A cylinder shaft seat and a pressure plate shaft seat are fixedly installed at the upper and lower ends of the side surface of the installation plate, respectively. The cylinder shaft seat is rotatably connected to one end of the pressure plate cylinder via a shaft. The pressure plate shaft seat is connected to one end of the pressure plate flipping block via a shaft. The other end of the pressure plate flipping block is connected to the piston rod of the pressure plate cylinder. A pressure plate is fixedly connected to the outer surface of the pressure plate flipping block. The pressure plate extends out of the workbench and is located above the workbench. The pressure plate is flipped up and down by the pressure plate cylinder to movably press against the upper surface of the folded working surface.

[0008] Preferably, the workbench surface is provided with a plurality of small suction holes, which are distributed in the middle and near the edge of the folded working surface; a vacuum pump is installed inside the workbench, and the suction end of the vacuum pump is connected to the suction holes through the suction chamber.

[0009] Preferably, the mounting base is further provided with a translational carrier suction cup mechanism, which includes a support column. A rodless cylinder is fixedly installed at the upper end of the support column. The slider of the rodless cylinder is connected to the translational platform. A pneumatic slide is installed on the side of the translational platform. A sliding seat is slidably connected to the outer side of the pneumatic slide. A swing cylinder is fixedly installed below the sliding seat. The output end of the swing cylinder is connected to the suction cup frame. A plurality of suction cups are installed on the lower surface of the suction cup frame. A suction cup vacuum pump is fixedly installed on the upper surface of the suction cup frame.

[0010] Preferably, an identification sensor is fixedly installed inside the workbench, and the sensing end of the identification sensor passes through the workbench and corresponds to the upper surface of the folded work surface.

[0011] Preferably, a positioning mounting frame is fixedly installed under the workbench by a support column, and a cam sleeve and a quick-change handle are installed on the positioning mounting frame; a positioning column is vertically installed on the upper surface of the mounting base, the positioning column is movably inserted into the cam sleeve, a locking hole is opened on the surface of the mounting base, and the locking end of the quick-change handle is movably connected in the locking hole.

[0012] Preferably, handles are installed on opposite sides of the workbench.

[0013] This invention provides an automatic folding device for an intelligent sewing workstation, offering the following advantages: By controlling the piston rod of the pressure plate cylinder to extend, the pressure plate flipping block rotates around a pivot. This, in turn, leverages the lever principle to cause the pressure plate to flip downwards, pressing it against the fabric on the upper surface of the folding work surface. This achieves a pressing and fixing effect on the fabric, preventing fabric displacement during subsequent folding operations and ensuring the fabric remains flat and fixed. Furthermore, by activating a rotary motor, the output shaft drives a rotating shaft to rotate, which in turn causes the folding plate to flip synchronously around the rotating shaft and the driven shaft, allowing the fabric to be folded under the action of the folding plate. This achieves automated fabric folding, improves production efficiency, ensures folding accuracy, and meets the demands of high-quality production. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] Example 1, as Figure 1-4 As shown, an automatic folding device for an intelligent sewing workstation includes a mounting base 1, a worktable 2 fixedly mounted on the mounting base 1, a folding working surface 3 on the upper surface of the worktable 2, a folding plate 8 on the upper side of the folding working surface 3, a rotary motor 5 fixedly mounted on the left side of the worktable 2 via a fixed seat 4, the output shaft of the rotary motor 5 being drivenly connected to a rotary shaft 6, and a driven shaft 7 being rotatably connected to the right side of the folding working surface 3 via a bearing, the axis of the driven shaft 7 coinciding with the axis of the rotary shaft 6, and both the rotary shaft 6 and the driven shaft 7 being fixedly connected to one side of the folding plate 8.

[0024] An installation plate 9 is vertically installed inside the workbench 2. A cylinder shaft seat 10 and a pressure plate shaft seat 11 are fixedly installed at the upper and lower ends of the side surface of the installation plate 9, respectively. The cylinder shaft seat 10 is rotatably connected to one end of the pressure plate cylinder 12 through a rotating shaft. The pressure plate shaft seat 11 is connected to one end of the pressure plate flipping block 13 through a rotating shaft. The other end of the pressure plate flipping block 13 is connected to the piston rod of the pressure plate cylinder 12. A pressure plate 14 is fixedly connected to the outer surface of the pressure plate flipping block 13. The pressure plate 14 extends out of the workbench 2 and is located above the workbench 2. The pressure plate 14 is flipped up and down through the pressure plate cylinder 12 to press it onto the upper surface of the folded working surface 3.

[0025] Working principle:

[0026] During use, the fabric to be folded is first moved to the designated position on the folding working surface 3 of the workbench 2 by the translation carrier mechanism of the preceding process. (In this embodiment, a vision sensor can be installed above the workbench 2 to identify whether the fabric position is correct. The signal output terminal of the vision sensor is connected to the signal input terminal of the controller, and the signal output terminal of the controller is connected to the control port of the translation carrier suction cup mechanism to control the translation carrier suction cup mechanism to precisely control the movement position of the fabric. The vision sensor and controller adopt a well-known solution in the prior art, which is known to those skilled in the art and will not be described in detail here.) Then, the piston rod of the pressure plate cylinder 12 is extended to push the pressure plate flipping block 13 to rotate around the pivot. Then, through the lever principle, the pressure plate 14 is flipped downward and pressed onto the fabric on the upper surface of the folding working surface 3, thereby achieving the effect of pressing and fixing the fabric to avoid the problem of fabric displacement during subsequent folding operations and ensuring that the fabric is flat and fixed. Then, the rotary motor 5 is started, and the output shaft of the rotary motor 5 drives the rotary shaft 6 to rotate, which in turn drives the folding plate 8 to rotate synchronously around the rotary shaft 6 and the driven shaft 7, so that the fabric is folded under the action of the folding plate 8.

[0027] Next, the piston rod of the pressure plate cylinder 12 is slightly retracted to reduce the pressure of the pressure plate 14 on the fabric, facilitating the smooth removal of the fabric later. Then, the suction cup mechanism of the subsequent translation carrier is controlled to pick up the folded fabric from the upper surface of the folding work surface 3 and move it to the next workstation, ensuring the fabric is flat and wrinkle-free. Afterward, the piston rod of the pressure plate cylinder 12 is retracted to its initial position, restoring the pressure plate 14 to its initial state, ready for the next round of fabric folding. The entire process, precisely coordinated by the control system, ensures efficient and consistent fabric folding, suitable for mass production needs.

[0028] In Example 2, as a further preferred embodiment of Example 1, the upper surface of the workbench 2 is provided with several small suction holes 15, which are distributed in the middle and near the edge of the folding working surface 3. A vacuum pump 16 is installed inside the workbench 2, and the suction end of the vacuum pump 16 is connected to the suction holes 15 through the suction chamber. Therefore, after the preceding process's translation carrier suction cup mechanism moves the fabric to the designated position on the folding working surface 3, the vacuum pump 16 can be turned on to generate negative pressure in the suction holes 15, firmly adhering the fabric to the workbench 2, further preventing fabric displacement and ensuring folding accuracy. After the fabric is folded by the folding plate 8, the vacuum pump 16 is turned off to release the negative pressure in the suction holes 15, making it easier for the fabric to be smoothly adsorbed and removed by the subsequent process's translation carrier suction cup mechanism, ensuring a smooth and accurate folding process and improving production efficiency.

[0029] In Example 3, as a further preferred embodiment of Example 1, an identification sensor 29 is fixedly installed inside the workbench 2. The sensing end of the identification sensor 29 passes through the workbench 2 and corresponds to the upper surface of the folding working surface 3. Specifically, the identification sensor 29 can be an infrared sensor (this is prior art and will not be described in detail here). The signal output end of the identification sensor 29 is connected to the signal input end of a controller. The signal output end of the controller is connected to the control end of the rotary motor 5 and the control end of the pressure plate cylinder 12. When the fabric moves to the folding working surface 3, the identification sensor 29 can quickly detect the fabric and transmit the signal to the controller, thereby controlling the rotary motor 5 and the pressure plate cylinder 12 to operate. The controller adopts a well-known solution in the prior art, which is understood by those skilled in the art and will not be described in detail here.

[0030] Example 4, as Figure 5 As shown, as a further preferred embodiment, the mounting base 1 is also provided with a translational carrier suction cup mechanism. The translational carrier suction cup mechanism includes a support column 21, a rodless cylinder 22 is fixedly installed on the upper end of the support column 21, the slider of the rodless cylinder 22 is connected to the translational platform 23, a pneumatic slide 24 is installed on the side of the translational platform 23, a sliding seat 25 is slidably connected to the outside of the pneumatic slide 24, a swing cylinder 26 is fixedly installed below the sliding seat 25, the output end of the swing cylinder 26 is connected to the suction cup frame 27, a number of suction cups are installed on the lower surface of the suction cup frame 27, a suction cup vacuum pump 28 is fixedly installed on the upper surface of the suction cup frame 27, and the suction cup vacuum pump 28 is connected to the suction cups through a pipeline; the suction cup frame 27 corresponds to the upper surface of the folding working surface 3.

[0031] Therefore, after the fabric sewing process is completed, the rodless cylinder 22 can be activated to move the translation platform 23. Then, the pneumatic slide 24 and the swing cylinder 26 can be controlled to work together to make the suction cup frame 27 accurately align with the fabric. Then, the suction cup vacuum pump 28 can be activated to ensure that the suction cup frame 27 can firmly adhere to the sewn fabric. After that, the rodless cylinder 22 can be activated to move the translation platform 23. The pneumatic slide 24 and the swing cylinder 26 can be controlled to work together to move the fabric precisely to the predetermined position on the folding work surface 3, ensuring the accurate positioning of the fabric before folding.

[0032] In this embodiment, a controller can be provided, with its signal output terminal connected to the signal input terminals of the rodless cylinder 22, pneumatic slide 24, swing cylinder 26, suction cup vacuum pump 28, and vision sensor, respectively. The vision sensor monitors the fabric position and status in real time and feeds the data back to the controller. Based on the feedback information, the controller dynamically adjusts the operating parameters of the rodless cylinder 22, pneumatic slide 24, swing cylinder 26, and suction cup vacuum pump 28, thereby precisely controlling the coordinated operation of each component, further optimizing the accuracy of fabric transfer and positioning, and improving the overall automation level. This is suitable for high-precision, high-volume production needs. The controller uses a well-known solution in the prior art, which is already understood by those skilled in the art and will not be described in detail here.

[0033] In Example 5, as a further preferred embodiment of Example 1, a positioning mounting frame 17 is fixedly installed under the workbench 2 via a support column. Multiple cam sleeves 18 and multiple quick-change handles 19 are mounted on the positioning mounting frame 17. A positioning column is vertically mounted on the upper surface of the mounting base 1, and the positioning column is movably inserted into the cam sleeve 18. A locking hole is provided on the surface of the mounting base 1, and the locking end of the quick-change handle 19 is movably connected to the locking hole. Therefore, as needed, by rotating the knob of the quick-change handle 19, the locking end of the quick-change handle 19 can be disengaged from the locking hole, thereby allowing the entire workbench 2 to detach from the mounting base 1. This allows for quick replacement of workbenches of different specifications to adapt to diverse production needs. When installing the workbench 2, the positioning hole in the center of the cam sleeve 18 under the workbench 2 can be aligned with the positioning column on the mounting base 1 to achieve rapid and accurate positioning of the workbench 2. Then, by rotating the knob of the quick-change handle 19, the quick-change handle 19 is re-locked to the mounting base 1, ensuring the workbench 2 is securely fixed.

[0034] In Example 6, as a further preferred embodiment of Example 5, handles 20 are installed on opposite sides of the workbench 2. Therefore, when the entire workbench 2 is detached from the mounting base 1, the workbench 2 can be directly removed from the mounting base 1 using the handles 20, facilitating maintenance and replacement.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
