[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0027] Figure 1 A schematic diagram of the three-dimensional structure of the pin assembly tool provided in the embodiment of the present application is shown. Figure 4 A schematic structural diagram of a winding braiding device provided in an embodiment of the present application is shown.

[0028] like Figure 1 and Figure 4 As shown, an embodiment of the present application provides a pin assembly tool 1 for inserting a pin P into a mounting groove C of a knitting tool 2. The pin assembly tool 1 includes: a base 10, a clamp 11 and a fault detection component 12.

[0029] The clamp 11 is connected to the base 10, and includes a pair of clamping jaws 110 arranged opposite to each other, and the pair of clamping jaws 110 are used to clamp the pin P and insert the pin P into the mounting groove C. In one example, the pin P is a U-shaped pin with two pins. In another example, the pin P is an I-shaped pin with one pin.

[0030] The fault detection component 12 is connected to the base 10. The fault detection component 12 includes a movable plate 120 located between a pair of jaws 110 and a first sensor 121 located between the base 10 and the movable plate 120. The movable plate 120 is movable in the vertical direction. If the depth of the pin P inserted into the mounting groove C does not meet the preset requirements, the movable plate 120 is lifted by the pin P and abuts against the first sensor 121 to trigger the first sensor 121 to send an electrical signal.

[0031] In this embodiment, when a pair of clamping jaws 110 grabs the pin P and inserts the pin P into the mounting groove C of the knitting tool 2, if the pin P is tilted so that the depth of its insertion into the mounting groove C is insufficient, an upward resistance will be generated between the pin of the pin P and the mounting groove C. Since the surface of the pin P and the clamping jaws 110 are smooth, the pin of the pin P will move upward after being subjected to resistance, and at the same time, the movable plate 120 will be lifted up, so that the movable plate 120 moves upward and abuts against the first sensor 121, so as to trigger the first sensor 121 to send an electrical signal. The electrical signal can be used to remind the assembler in the form of sound or picture. After receiving the electrical signal, the assembler can repair the unqualified pins. If the depth of the pin P inserted into the mounting groove C meets the preset requirements, the movable plate 120 will be in the original position and will not trigger the first sensor 121 to send an electrical signal.

[0032] The pin assembly tool provided in the embodiment of the present application adds a fault detection component 12 to the base 10, and the fault detection component 12 includes a movable plate 120 located between a pair of clamping jaws 110 and a first sensor 121 located between the base 10 and the movable plate 120. The movable plate 120 is movable in the vertical direction. If the depth of the pair of clamping jaws 110 clamping the pin P and inserting it into the installation slot C does not meet the preset requirements, the movable plate 120 is lifted up by the pin P and abuts against the first sensor 121 to trigger the first sensor 121 to send an electrical signal. Therefore, while the pin assembly tool meets the basic clamping function of the clamping jaws 110, it also adds a detection function of whether the pin P is inserted into the installation slot C, so as to replace the high-cost image detection, improve the assembly quality of the pin P, and has a simple structure and low cost, which effectively improves the competitiveness of the product.

[0033] Figure 2 Show Figure 1 A schematic structural diagram of the guide assembly of the pin assembly tool is shown.

[0034] In some embodiments, the fault detection component 12 also includes a guide component 122 located between the base 10 and the movable plate 120, the guide component 122 includes a guide rod 122A, and the movable plate 120 is provided with a through hole allowing the guide rod 122A to pass through. When the movable plate 120 is lifted by the pin P, the movable plate 120 can move in the vertical direction.

[0035] like Figure 2 As shown, the guide assembly 122 is arranged between the base 10 and the movable plate 120, and the guide rod 122A passes through the through hole of the movable plate 120. When the movable plate 120 is lifted by the pin P, the guide rod 122A can guide the movable plate 120 to move in the vertical direction to prevent the movable plate 120 from offsetting and accidentally touching or failing to touch the first sensor 121, resulting in the fault detection assembly 12 being unable to detect the pin failure problem in time.

[0036] In some embodiments, the guide assembly 122 also includes a guide sleeve 122B and an elastic member 122C respectively sleeved on the outer peripheral side of the guide rod 122A, and the elastic member 122C is located between the guide sleeve 122B and the movable plate 120. When the movable plate 120 is lifted by the pin P, the elastic member 122C is compressed so that the movable plate 120 abuts against the first sensor 121.

[0037] The guide sleeve 122B is sleeved on the outer peripheral side of the guide rod 122A, and the length of the guide sleeve 122B is less than the length of the guide rod 122A. Optionally, the elastic member 122C is a spring. The elastic member 122C is sleeved on the outer peripheral side of the guide rod 122A, and the elastic member 122C is located between the guide sleeve 122B and the movable plate 120. When the movable plate 120 is lifted by the pin P, the elastic member 122C is compressed so that the movable plate 120 abuts against the first sensor 121. The elastic member 122C can buffer the impact force on the movable plate 120 when it is lifted by the pin P. When the fault of the pin P is eliminated, the elastic member 122C pushes the movable plate 120 to return to its original position.

[0038] Furthermore, the number of the guide assemblies 122 is two, and the two guide assemblies 122 are arranged at intervals along the length direction of the movable plate 120 .

[0039] like Figure 2 As shown, the two guide assemblies 122 are spaced apart along the length direction of the movable plate 120 , which can balance the upward resistance of the movable plate 120 when it is lifted by the pins P, thereby preventing the movable plate 120 from tilting and failing to trigger the first sensor in time.

[0040] Figure 3 Show Figure 1 A schematic structural diagram of a pair of clamping jaws of a pin assembly tool is shown.

[0041] In some embodiments, a pair of clamping jaws 110 are respectively provided with a first clamping portion 111 and a second clamping portion 112 at the ends thereof, a first notch J1 is provided on the side of the first clamping portion 111 facing the second clamping portion 112, and a second notch J2 is correspondingly provided on the side of the second clamping portion 112 facing the first clamping portion 111, and the first clamping portion 111 and the second clamping portion 112 are interlocked with each other to form a clamping cavity for clamping the pin P between the first notch J1 and the second notch J2.

[0042] like Figure 3 As shown, the ends of the pair of clamping jaws 110 are respectively provided with a first clamping portion 111 and a second clamping portion 112, and a clamping cavity for clamping the plug pin P is formed between the first notch J1 of the first clamping portion 111 and the second notch J2 of the second clamping portion 112. When the pair of clamping jaws 110 move in a direction approaching each other, the plug pin P can be clamped through the clamping cavity formed by the first notch J1 and the second notch J2, and the plug pin P can be inserted into the corresponding installation slot C; when the plug pin P is assembled in place, the pair of clamping jaws 110 move in a direction away from each other to release the plug pin P.

[0043] Furthermore, the number of the first notch J1 and the number of the second notch J2 are respectively multiple, the multiple first notches J1 are arranged at intervals along the length direction of the first clamping portion 111, and the multiple second notches J2 are arranged at intervals along the length direction of the second clamping portion 112; one first notch J1 and a corresponding second notch J2 are used to clamp a pin of the pin P.

[0044] When the pin P is a U-shaped pin with two pins, one first notch J1 and one corresponding second notch J2 are used to clamp one pin of the pin P. One pin P needs to clamp two pins of the pin P through two first notches J1 and corresponding second notches J2. When there are multiple first notches J1 and second notches J2, multiple types of pins P can be clamped and assembled, thereby improving the versatility of the pin assembly tooling.

[0045] In addition, in order to assemble as many types of pins P as possible within the limited length range of the first clamping portion 111 and the second clamping portion 112, a first notch J1 and a corresponding second notch J2 located at the edge can be used as a positioning reference for one pin of the pin P, and other first notches J1 and corresponding second notches J2 are set as clamping cavities for another pin of a different type of pin P, so as to reduce the number of first notches J1 and corresponding second notches J2. For example, Figure 3 A total of five first notches J1 and corresponding second notches J2 are provided for assembling pins P of four different sizes and types.

[0046] It is understandable that when the plug pin P is an I-type pin with one pin, one of the plug pins P needs to be clamped by a first notch J1 and a corresponding second notch J2.

[0047] Furthermore, the first clamping portion 111 is also provided with a concave portion T1 or a convex portion T2 adjacent to the first notch J1, and the second clamping portion 112 is correspondingly provided with a convex portion T2 or a concave portion T1 adjacent to the second notch J2, and the first clamping portion 111 and the second clamping portion 112 are mutually interlocked through the concave portion T1 and the convex portion T2. ​​When the first clamping portion 111 is provided with a concave portion T1 adjacent to the first notch J1, the second clamping portion 112 is correspondingly provided with a convex portion T2 adjacent to the second notch J2; when the first clamping portion 111 is provided with a convex portion T2 adjacent to the first notch J1, the second clamping portion 112 is correspondingly provided with a concave portion T1 adjacent to the second notch J2. In this way, the first clamping portion 111 and the second clamping portion 112 can be closely interlocked with each other through the concave portion T1 and the convex portion T2, thereby improving the clamping force of the pair of clamping jaws 110.

[0048] Furthermore, the pin clamping tool 1 further includes a cylinder assembly (not shown in the figure), which is respectively connected to a pair of clamping jaws 110, and is used to drive the pair of clamping jaws 110 to move back and forth to clamp or release the pin P, and the cylinder assembly further includes a pressure regulating valve for adjusting the clamping force of the clamping jaws 110. The pressure regulating valve can adjust the clamping force of the pair of clamping jaws 110 to ensure that the clamping force of the pin P is just enough to assemble it into the installation groove C and does not scratch the surface due to excessive clamping force.

[0049] In some embodiments, the pin clamping tool 1 further includes an in-situ detection component 13, which is connected to at least one clamping jaw 110, and includes a second sensor 131, which is used to detect whether the pin P is clamped between a pair of clamping jaws 110. The second sensor 131 is fixedly connected to the clamping jaw 110 through a connector.

[0050] like Figure 1 and Figure 4 As shown, since the knitting tool 2 is usually provided with a plurality of mounting slots C, if the pair of clamping jaws 110 fails to clamp the pin P during the process of assembling the pin P, the pin P will not lift up the movable plate 120, and the fault detection component 12 will mistakenly judge that the pin P is assembled properly because it does not receive the electrical signal of the first sensor 121. To solve this problem, the present embodiment provides a position detection component 13 on at least one clamping jaw 110, and first detects whether the pair of clamping jaws 110 clamps the pin P before assembling the pin P, and then performs the assembly process of the pin P, which can further improve the assembly quality of the pin P.

[0051] like Figure 4 As shown, the embodiment of the present application also provides a winding braiding device, including: a braiding tool 2 and a pin assembly tool 1 as described above. The braiding tool 2 has a mounting groove C, and the pin assembly tool 1 is located above the braiding tool 2. The pin assembly tool 1 clamps the pin P through a pair of clamping claws 110 and inserts the pin P into the mounting groove C.

[0052] Therefore, the winding braiding equipment provided in the embodiment of the present application, by adding a fault detection component 12 to the base 10 of the pin assembly tool 1, not only does the pin assembly tool satisfy the basic clamping function of the clamping jaws 110, but also adds a detection function of whether the pin P is inserted into the installation slot C, so as to replace the high-cost image detection, improve the assembly quality of the pin P, and has a simple structure and low cost, which effectively improves the competitiveness of the product. In addition, an in-situ detection component 13 is also provided on at least one side of the clamping jaws 110. Before assembling the pin P, it is first detected whether a pair of clamping jaws 110 have clamped the pin P, and then the assembly process of the pin P is performed, which can further improve the assembly quality of the pin P. At the same time, a pair of clamping jaws 110 can clamp pins P of various types and sizes, thereby improving the versatility of the pin assembly tool 1.
