Description

Technical Field

[0001] This application relates to the field of textile equipment manufacturing technology, and in particular to a front and back identification device and an automatic button attaching machine. Background Technology

[0002] In the field of textile equipment manufacturing technology, especially in garment making, button sewing is a crucial process. To reduce labor costs and improve production efficiency, many factories have adopted automatic button sewing machines for mass production. Traditional automatic button sewing machines typically rely on vision recognition systems or mechanical devices to identify the front and back of buttons. For standard button styles, traditional recognition devices can accurately determine the front and back by observing the button's shape, surface texture, color, and other characteristics.

[0003] However, for some special button designs, especially those with an arched front and a flat back, traditional identification devices struggle to accurately determine their orientation. This structural characteristic makes them visually unrecognizable, easily resulting in the front being face down during production. Incorrect identification of the button's orientation can lead to it being sewn on backwards, requiring disassembly and adjustment, causing unnecessary manual labor and processing waste, and impacting production efficiency. Utility Model Content

[0031] To address the problem of incorrect identification of the front and back of the test piece in related technologies, which leads to unnecessary manual operations and processing waste, firstly, refer to... Figure 1 and Figure 2 , Figure 1 This diagram shows a front and back identification device 10 according to one embodiment of the present invention. Figure 2 A schematic diagram of the dimensions of the front and back recognition device 10 is shown, where the units are millimeters. The front and back recognition device 10 is applied to an automatic button attaching machine 20. The front and back recognition device 10 includes a fixing unit 101, a positioning member 102, and a detection unit 103. The fixing unit 101 is formed on the front and back recognition device 10 and is used to fix the position of the front and back recognition device 10 on the automatic button attaching machine 20. The positioning member 102 is fixed on the front and back recognition device 10 and is used to adjust the position of the front and back recognition device 10 on the automatic button attaching machine 20. The detection unit 103 is used to identify the front and back of the test piece 50.

[0032] For example, the front and back recognition device 10 has a fixing unit 101 at its first end and a detection part 103 at its second end. The fixing unit 101 and the positioning member 102 are spaced apart, and the positioning member 102 is located between the fixing unit 101 and the detection part 103. The positioning member 102 can be integrally formed with the front and back recognition device 10. The shape of the front and back recognition device 10 is not specifically limited here, and the overall shape can be set as a strip.

[0033] In practical applications, the automatic button-attaching machine 20 typically needs to operate within a certain working range. Therefore, the fixing unit 101 in this embodiment not only interacts with the fixing screw 30 to fix the front and back identification device 10 on the automatic button-attaching machine 20, but also cooperates with the positioning member 102 to provide necessary support for the front and back identification device 10. Furthermore, the fixing unit 101 can cooperate with the positioning member 102 to adjust the position of the front and back identification device 10 on the automatic button-attaching machine 20 according to specific production needs. Adjusting the position of the front and back identification device 10 on the automatic button-attaching machine 20 can involve adjusting its position in both the horizontal and vertical directions of the automatic button-attaching machine 20.

[0034] Optionally, the positioning element 102 can be configured as a positioning nut, and the fixing unit 101 can be configured as a rectangular or elongated elliptical fixing through hole along the vertical direction. Through the rectangular or elongated elliptical fixing through hole along the vertical direction, and the structure of the positioning nut and screw, the position of the front / back identification device 10 in the first and second directions of the automatic button-attaching machine 20 can be adjusted, thereby allowing the front / back identification device 10 to meet the identification requirements of different models and sizes of test pieces 50. The interaction between the fixing through hole and the fixing screw 30, as well as the interaction between the positioning nut and the screw, enables the connection of the front / back identification device 10 to the automatic button-attaching machine 20. Simultaneously, the friction between the screw and the nut ensures that the front / back identification device 10 will not loosen after adjustment.

[0035] The detection unit 103 can determine the front and back of the test piece 50 by physical contact with its external shape. For example, the detection unit 103 can be configured as a slot, guide bar, cam, etc., of a specific shape. When the detection unit 103 contacts the test piece 50, it determines the front and back of the test piece 50 by the matching of its shape features with the slot or guide bar. Since the front and back of the test piece 50 have different shapes, they will react differently when entering the detection unit 103. For example, the front of the test piece 50 may fit perfectly with its shape, while the back of the test piece 50 may get stuck or slide unevenly due to incomplete fit, thus enabling the identification of the front and back of the test piece 50.

[0036] In actual operation, the operator can adjust the position of the front / back recognition device 10 in the first direction of the automatic button-attaching machine 20 through the rectangular or elongated elliptical fixing through hole. After the operator moves the front / back recognition device 10 to the target position in the first direction, the fixing unit 101 and the positioning element 102 are connected to the automatic button-attaching machine 20 by screws or positioning pins. The first direction of the automatic button-attaching machine 20 can be the vertical direction of the automatic button-attaching machine 20. When it is necessary to adjust the position of the front / back recognition device 10 in the second direction of the automatic button-attaching machine 20, the operator can remove the fixing screws or positioning pins and move the front / back recognition device 10 along the second direction of the automatic button-attaching machine 20. After the operator moves the front / back recognition device 10 to the target position in the second direction, the fixing unit 101 and the positioning element 102 are reconnected to the automatic button-attaching machine 20 by screws or positioning pins. Optionally, the fixing unit 101 can also be configured as a slide rail, locking component, etc., arranged along the direction of the slide rail 201 of the automatic button attaching machine 20, which can flexibly adjust the position of the front and back recognition device 10 in the second direction of the automatic button attaching machine 20 without disassembling the screws or positioning pins. The second direction of the automatic button attaching machine 20 can be the horizontal direction of the automatic button attaching machine 20, that is, the direction of the automatic button attaching machine 20 along its own slide rail 201.

[0037] In this embodiment, the fixing unit 101 is used to fix the front and back recognition device 10 on the automatic button attaching machine 20, and the positioning member 102 is used to cooperate with the fixing unit 101 to adjust the position of the front and back recognition device 10 on the automatic button attaching machine 20, so that the front and back recognition device 10 can recognize the front and back of test parts 50 of different sizes and shapes, thereby improving the versatility of the front and back recognition device 10. The detection unit 103 is used to identify the front and back of the test part 50, and can determine the front and back of the test part 50 through a non-electronic mechanical method, reducing the identification cost and maintenance cost; at the same time, the detection unit 103 can ensure the accuracy of front and back recognition by accurately detecting the external shape of the test part 50, avoiding unnecessary manual operation and processing waste, thereby improving production efficiency.

[0038] In an exemplary embodiment, the fixing unit 101 includes a plurality of fixing through holes, which are spaced apart.

[0039] The fixing unit 101 includes multiple fixing through holes arranged at specific intervals to ensure that the device 10 can be evenly stressed. The spacing between each fixing through hole is determined based on the size of the device 10, the stress conditions, and the actual usage environment. The shape and size of the fixing through holes are not specifically limited here. For example, the shape of the fixing through holes can be set as an oblong, oblong, or rectangular shape. The fixing through holes can be precisely designed according to the diameter of the screw or locating pin to ensure that the device 10 will not be loose or unstable when fixed.

[0040] In this embodiment, the fixing unit 101 includes multiple fixing through holes, which are spaced apart to ensure that the front and back recognition device 10 can be evenly distributed with force, so that the front and back recognition device 10 can be firmly fixed on the automatic button attaching machine 20 during installation, and to avoid displacement of the front and back recognition device 10 due to vibration or mechanical operation during operation, thereby affecting the accuracy of front and back recognition.

[0041] In one exemplary embodiment, the fixing unit 101 and the positioning member 102 are connected to the automatic button-attaching machine 20 by screwing or snapping.

[0042] Optionally, the fixing unit 101 interacts with the fixing screw 30 or the positioning pin to fix the front and back recognition device 10 in position on the automatic button attaching machine 20. The positioning element 102 is a positioning nut, which interacts with the positioning screw 40 or the positioning pin to connect the front and back recognition device 10 to the automatic button attaching machine 20.

[0043] In the previous exemplary embodiment, the fixing unit 101 is installed in conjunction with the fixing screw 30 to fix the front and back recognition device 10 to the slide 201 of the automatic button attaching machine 20.

[0044] For example, the slide 201 of the automatic button-attaching machine 20 is provided with a threaded hole that mates with the fixing screw 30. This threaded hole can cooperate with the fixing unit 101, allowing the fixing screw 30 to fix the front / back identification device 10 onto the slide 201 of the automatic button-attaching machine 20 through the cooperation between the threaded hole on the slide 201 and the fixing unit 101. The fixing screw 30 has a rounded head at one end away from the threaded hole, and the radius of this rounded head is larger than the radial distance of the fixing unit 101 in the horizontal direction. Having a rounded head at the end of the fixing screw 30 away from the threaded hole also prevents scratching the workpiece 50 being tested.

[0045] In this embodiment, the fixing unit 101 is installed in conjunction with the fixing screw 30 to fix the front and back recognition device 10 to the slide 201 of the automatic button attaching machine 20, which can improve the stability of the front and back recognition device 10.

[0046] In one exemplary embodiment, the positioning element 102 is a positioning nut, which is installed in conjunction with the positioning screw 40 to adjust the position of the detection unit 103 on the slide rail 201.

[0047] Optionally, the positioning nut has a locking function or an anti-loosening design to ensure the stability of the front / back recognition device 10's position under vibration or external force. The positioning nut works in conjunction with the positioning screw 40 to adjust the position of the front / back recognition device 10. For example, rotating the positioning screw 40 adjusts the position of the front / back recognition device 10 on the automatic button-attaching machine 20, thereby adjusting the position of the detection unit 103 on the slide rail 201 of the automatic button-attaching machine 20. Simultaneously, the positioning screw 40 and the positioning nut work together to ensure the front / back recognition device 10 is securely fixed on the automatic button-attaching machine 20.

[0048] In this embodiment, the precise position adjustment of the detection unit 103 on the slide rail 201 can be achieved by the cooperation of the positioning nut and the positioning screw 40. Furthermore, the threaded connection between the positioning nut and the positioning screw 40 ensures that the front and back recognition device 10 remains fixed at the target position, thereby avoiding recognition errors caused by positional deviation of the front and back recognition device 10 during the front and back recognition process.

[0049] In one exemplary embodiment, the positioning element 102 is fixedly connected to the front and back identification device 10 by welding.

[0050] The positioning component 102 is fixedly connected to the front and back recognition device 10 by welding, which can further ensure the stability of the positioning component 102 and the front and back recognition device 10, thereby ensuring the reliability of the connection between the front and back recognition device 10 and the automatic button attaching machine 20.

[0051] In one exemplary embodiment, the detection unit 103 is a slot, the shape of which is adapted to the shape of the target surface of the test piece 50.

[0052] Among them, the target surface of the test piece 50 refers to a specific surface on the test piece 50, such as the front surface of the test piece 50. The front surface of the test piece 50 may have a certain geometric shape, such as an arched surface, a plane, a curved surface, or a surface with a special structure.

[0053] Optional, such as Figure 3The diagram shows a structural schematic of a test piece 50 with an arched front and a flat back, and a detection unit 103. When identifying the front and back of a test piece 50 with an arched front and a flat back, the slotted shape is set to an arched surface. During the front and back identification process of the front-arched, flat-backed test piece 50 by the front-back identification device 10, when the front of the test piece 50 faces the detection unit 103, it can pass smoothly through the front and back identification device 10, indicating that the test piece 50 is in the front position. When the back of the test piece 50 faces the detection unit 103, it cannot pass through the front and back identification device 10, indicating that the test piece 50 is in the back position.

[0054] In this embodiment, the shape of the slotted arch surface is adapted to the shape of the target surface of the test piece 50, which can ensure that the detection unit 103 accurately contacts or embeds into the target surface of the test piece 50. In this way, the front and back sides of the test piece 50 can be accurately identified through the matching of the slot shape, avoiding unnecessary manual operation and processing waste in subsequent processing, thereby improving production efficiency.

[0055] In one exemplary embodiment, the front and back recognition device 10 is made of metal and can be flexibly bent and adjusted.

[0056] Metal materials possess high strength, rigidity, and wear resistance. The front / back recognition device 10 is made of metal, enabling it to withstand significant mechanical pressure, vibration, or friction during long-term use. Furthermore, the front / back recognition device 10 is elastically bendable, enhancing its flexibility. By adjusting its shape, it can precisely adapt to automatic button-attaching machines 20 of different specifications or shapes.

[0057] Secondly, see Figure 4 , Figure 4 A schematic diagram of an automatic button-attaching machine 20 according to an embodiment of the present invention is shown. The automatic button-attaching machine 20 includes the aforementioned front and back identification device 10. The slide rail 201 of the automatic button-attaching machine 20 has a threaded hole, and the fixing screw 30 is installed by cooperating with the threaded hole and the fixing unit 101 to fix the device 10 to the slide rail 201.

[0058] For example, after the operator moves the front and back recognition device 10 to the target position on the automatic button attaching machine 20, the fixing screw 30 is installed by cooperating with the threaded hole and the fixing unit 101 to connect the front and back recognition device 10 to the slide rail 201. Then, the front and back recognition device 10 is fixedly connected to the automatic button attaching machine 20 by cooperating with the positioning screw 40 and the positioning member 102.

[0059] The automatic button-attaching machine 20 includes an automatic button-attaching machine 20 switch. Exemplarily, in actual operation, after the front / back recognition device 10 is moved to the target position on the automatic button-attaching machine 20 and the front / back recognition device 10 is fixedly connected to the automatic button-attaching machine 20 via the fixing unit 101 and the positioning member 102, the automatic button-attaching machine 20 switch is turned on to start the automatic button-attaching machine 20. This causes the test piece 50 to move upwards along the slide 201 of the automatic button-attaching machine 20 from the bottom of the automatic button-attaching machine 20 to the detection section 103 of the front / back recognition device 10, due to the vibration of the automatic button-attaching machine 20. Figure 4 The direction indicated by the middle arrow is the direction of vibration movement of the test piece 50. If the test piece 50 moves to the detection section 103 of the front / back recognition device 10 and passes through the detection section 103 smoothly, it indicates that the test piece 50 is in the front position, and the test piece 50 will continue to be sent to the next process. If the test piece 50 moves to the detection section 103 of the front / back recognition device 10 but cannot pass through the detection section 103, it indicates that the test piece 50 is in the back position, and the test piece 50 will be blocked, separated, and dropped to the bottom of the automatic button attaching machine 20 for re-recognition.

[0060] In one exemplary embodiment, since the test piece 50 has various types and sizes, a plurality of front and back identification devices 10 are provided to match the various test pieces 50 according to their types and sizes.

[0061] Optionally, before moving the front and back recognition device 10 to the target position on the automatic button attaching machine 20 and fixing the front and back recognition device 10 to the automatic button attaching machine 20 by the fixing unit 101 and the positioning member 102, the front and back recognition device 10 is further selected according to the type and size of the test piece 50 to match the test piece 50.

[0062] In this embodiment, the front and back identification device 10 is replaced according to the different types and sizes of the test piece 50, which can enhance the versatility and flexibility of the automatic button attaching machine 20 and ensure the accuracy of the identification of the test piece 50.

[0063] In one exemplary embodiment, 144 pieces of each of four different sizes of test pieces 50 are selected, totaling 576 test pieces 50. A front / back identification device 10, matching the front / back of each of the four different sizes of test pieces 50, is used on the automatic button-attaching machine 20 to identify the front / back of the test pieces 50. Specifically, for each size of test piece 50, after determining the matching front / back identification device 10, the position of the front / back identification device 10 on the automatic button-attaching machine 20 is adjusted by the cooperation of the positioning member 102 and the fixing unit 101, so that the detection unit 103 can perform the front / back identification work more smoothly and accurately.

[0064] In another embodiment, a front / back identification device 10 is provided for use in an automatic button attaching machine 20. The device 10 includes:

[0065] A fixing unit 101 is provided on the device 10. The fixing unit 101 is used to fix the device 10 in position on the automatic button attaching machine 20. The fixing unit 101 includes a plurality of fixing through holes, which are spaced apart. The fixing unit 101 is installed in conjunction with the fixing screw 30 to fix the device 10 to the slide rail 201 of the automatic button attaching machine 20.

[0066] Positioning component 102 is fixed to the device 10 and is used to adjust the position of the device 10 on the automatic button-attaching machine 20. Positioning component 102 is a positioning nut, which is installed in conjunction with positioning screw 40 and is used to adjust the position of the detection unit 103 on the slide rail 201. Positioning component 102 is fixedly connected to the device 10 by welding.

[0067] The detection unit 103 is used to identify the front and back sides of the test piece 50. The detection unit 103 is a slot, and the shape of the slot is adapted to the shape of the target surface of the test piece 50.

[0068] The front and back recognition device 10 is made of metal and can be flexibly bent and adjusted.

[0069] An automatic button attaching machine 20 includes the aforementioned front and back identification device 10. The automatic button attaching machine 20 has threaded holes on its slide rail 201, and fixing screws 30 are installed by engaging with the threaded holes and fixing unit 101 to fix the device 10 to the slide rail 201.

[0070] In this embodiment, the fixing unit 101 includes multiple fixing through holes spaced apart to ensure that the front and back recognition device 10 can be evenly distributed with force. This allows the front and back recognition device 10 to be securely fixed to the automatic button-attaching machine 20 during installation, preventing displacement of the front and back recognition device 10 due to vibration or mechanical operation during operation, which would affect the accuracy of front and back recognition. The precise position adjustment of the detection unit 103 on the slide 201 can be achieved through the cooperation of the positioning nut and positioning screw 40. Furthermore, the threaded connection between the positioning nut and positioning screw 40 ensures that the front and back recognition device 10 remains fixed at the target position, thus avoiding recognition errors caused by positional deviation of the front and back recognition device 10 during the front and back recognition process. The detection unit 103 is a slotted part. The shape of the slotted arched surface is adapted to the shape of the target surface of the test piece 50. This ensures that the detection unit 103 accurately contacts or embeds into the target surface of the test piece 50. Through the matching of the slot shape, the front and back of the test piece 50 can be accurately identified, avoiding unnecessary manual operation and processing waste in subsequent processing, thereby improving production efficiency.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
