This traditional detection method has the disadvantages of high labor intensity, low detection speed, susceptibility to human subjective factors, high false detection rate and missed detection rate, and inconvenient data processing. Based on this, we designed a detection mechanism that is convenient for rapid detection of seam defects at the seam interface of the fabric. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1-8 The utility model provides the following technical solutions: A fabric sewing interface detection mechanism, comprising: a pressing component 1, a driving component 2 and a detection component 3, the pressing component 1 is used to press on the fabric sewing interface, the driving component 2 is installed at the top of the pressing component 1, the driving component 2 is used to drive the pressing component 1 to move up and down, the detection component 3 is installed on the top of the pressing component 1, and the detection component 3 is used to detect whether the fabric sewing interface is qualified.

[0023] In this embodiment, the clamping assembly 1 includes a U-shaped seat 11, a fixed seat 12 is installed at the top of the U-shaped seat 11, a spring plate 13 is installed at the bottom of the fixed seat 12, a movable block 14 is rotatably installed at the bottom of the U-shaped seat 11, a roller 15 is rotatably installed on one side of the movable block 14, one end of the spring plate 13 is tightly attached to the top of the movable block 14, and an induction plate 16 is installed on one side of the roller 15.

[0024] Specifically, the driving component 2 drives the U-shaped seat 11 to descend so that the roller 15 fits the fabric sewing interface, and the provided spring piece 13 enables the roller 15 to be pressed on the fabric sewing interface, and the fabric is pulled to move by the pulling device, so that the fabric sewing interface will move at the bottom of the roller 15. When the defect at the fabric sewing interface moves to the bottom of the roller 15, the roller 15 will drive the movable block 14 to squeeze the spring piece 13 upward under the action of the defect, and then the roller 15 will drive the sensor piece 16 to rise and approach the detection component 3. The detection component 3 detects this action and determines that there is a defect at this location of the fabric sewing interface. In this way, the fabric sewing interface can be effectively and quickly detected, which greatly improves the detection efficiency while reducing the false detection rate and missed detection rate.

[0025] In this embodiment, the detection component 3 includes a connecting plate 31 installed on the top of the front of the U-shaped seat 11, and an adjustment seat 32 is fixedly installed on the front of the connecting plate 31. An adjustment groove 33 is opened on the front of the adjustment seat 32, and two guide rods 34 are installed in the adjustment groove 33. The guide rods 34 are interlaced with the adjustment block 35. An adjusting bolt 36 is threadedly installed on the top of the adjustment seat 32, and the bottom end of the adjusting bolt 36 extends into the adjustment groove 33 and is rotatably connected to the top of the adjustment block 35. A fixing part 37 is fixedly installed on the front of the adjustment block 35, and a proximity switch 38 is installed on one side of the fixing part 37.

[0026] Specifically, the staff can adjust the distance between the proximity switch 38 and the sensor sheet 16 according to the thickness of the fabric to be detected. By rotating the adjusting bolt 36, since the bottom end of the adjusting bolt 36 is rotatably connected to the top of the adjusting block 35, the adjusting bolt 36 can drive the adjusting block 35 to rise and fall in the adjusting slot 33 along the direction of the guide rod 34, and the fixing part 37 is fixedly installed on the front side of the adjusting block 35. Therefore, in this way, the distance between the proximity switch 38 and the sensor sheet 16 can be adjusted, so that the sewing interface detection of fabrics of different thicknesses can be realized.

[0027] In this embodiment, the driving assembly 2 includes a mounting base 21, a mounting plate 22 is fixedly connected to the front of the mounting base 21, a driving cylinder 23 is installed at the top of the mounting base 21, and the telescopic end of the driving cylinder 23 extends to the bottom of the mounting base 21 and is connected to the top of the U-shaped base 11.

[0028] Specifically, the mechanism is mounted on the detection device via the mounting plate 22 , and the U-shaped seat 11 can be driven down by driving the cylinder 23 , so that the roller 15 is pressed tightly against the fabric sewing interface.

[0029] In this embodiment, a mounting groove 4 is provided on the back of the U-shaped seat 11, a limit plate 5 is installed in the mounting groove 4, an opening 6 is provided in the middle of the limit plate 5, one end of the movable block 14 extends into the opening 6 and the end of the movable block 14 is close to the top of the opening 6 when the roller 15 does not contact the fabric.

[0030] Specifically, through the opening 6, one end of the movable block 14 extends into the opening 6, and under the action of the spring 13, one end of the movable block 14 can be pressed downward, so that when the roller 15 does not contact the cloth, the other end of the movable block 14 will be close to the top of the opening 6, thereby limiting the downward tilt angle of the movable block 14 in this way.

[0031] In this embodiment, the sensor plate 16 is located on the side of the proximity switch 38 and at the bottom of the proximity switch 38 .

[0032] Specifically, through this arrangement, when the roller 15 contacts the defect and moves upward, the sensor plate 16 will move upward and approach the proximity switch 38, and then the proximity switch 38 and the sensor plate 16 can cooperate to quickly detect the defects at the seam interface of the fabric.

[0033] Working principle: The driving cylinder 23 drives the clamping assembly 1 to descend so that the roller 15 is pressed on the fabric sewing interface, and the fabric is pulled horizontally by the pulling device, so that the fabric sewing interface will move at the bottom of the roller 15. When there is a defect at the fabric sewing interface and a sewing bulge is generated, the roller 15 will drive the movable block 14 to squeeze the spring piece 13 upward. At this time, the sensor piece 16 will move upward and close to the proximity switch 38. In this way, the part with defects in the fabric sewing interface can be quickly detected, and the height of the proximity switch 38 can be adjusted by the adjustment bolt 36 and the adjustment block 35, thereby adjusting the distance between the proximity switch 38 and the sensor piece 16. In this way, defects at the fabric sewing interfaces of different thicknesses can be detected conveniently. This detection method is convenient, fast and more efficient, with higher detection accuracy, which greatly reduces the missed detection rate.
