[0033] Example

[0034] Reference Figure 1 As shown, this embodiment provides a thread end connection terminal, including a frame 1, a clamping assembly and a thread end connection device 2. The clamping assembly includes two groups of jaw assemblies, and each group of jaw assemblies is used to clamp a thread end. Specifically, each group of jaw assemblies includes two jaws for clamping or loosening the thread end. In this embodiment, the jaws are pneumatic jaws, and the air pressure inside the jaws is changed by an air pump to deform the jaws to clamp the thread end. The specific structure of the pneumatic jaws can be selected from the prior art, and other forms of jaws can also be selected in other embodiments. The jaws are connected to the frame 1, and the two jaws of the same group of jaw assemblies are aligned to clamp the same thread end. The two groups of jaw assemblies clamp the two thread ends respectively and arrange the two thread ends crosswise.

[0035] Specifically, the thread end connecting device 2 is located between two jaws of the same group of jaw assemblies; the thread end connecting device 2 is connected to the frame 1 through a moving assembly 3, and the moving assembly 3 drives the thread end connecting device 2 to move in a direction close to or away from the thread end. The thread end connecting device 2 is used to twist and splice two crossed thread ends.

[0036] When two thread ends need to be connected, the moving component 3 is used to drive the thread end connection device 2 to move away from the clamping claws to reserve a certain space for the clamping claws to clamp the thread ends. The thread end connection end is moved as a whole so that the two sets of clamping claw components clamp the two thread ends respectively and make the two thread ends cross. Then the moving component 3 is used to drive the thread end connection device 2 to move toward the direction close to the thread ends until the thread ends enter the working area of ​​the thread end connection device 2, and the pneumatic thread end connection device 2 splices the two thread ends.

[0037] The thread end connection device 2 provided in this embodiment can directly clamp the hanging yarn through the clamping claws, and can clamp two thread ends that need to be connected to form a cross shape by changing the position of the thread end connection end, which is convenient for connection; by driving the thread end connection device 2 to move, the thread end clamping state and the yarn twisting state can be switched to avoid interference caused by the thread end connection device 2 during the clamping process. The thread end connection end has a simple overall structure, low cost, and each module is completely independent, easy to maintain, and a simple thread end connection process.

[0038] Specifically, refer to Figure 1 and Figure 2 As shown, the clamping jaw assembly is divided into a first group of clamping jaw assemblies and a second group of clamping jaw assemblies. The first group of clamping jaw assemblies includes a first clamping jaw 41 and a second clamping jaw 42. The clamping groove of the first clamping jaw 41 is aligned with the clamping groove of the second clamping jaw 42 and arranged along a first straight line direction 45. The second group of clamping jaw assemblies includes a third clamping jaw 43 and a fourth clamping jaw 44. The clamping groove of the third clamping jaw 43 is aligned with the clamping groove of the fourth clamping jaw 44 and arranged along a second straight line direction 46. The first clamping jaw 41 and the third clamping jaw 43 are located on the same side, and the second clamping jaw 42 and the fourth clamping jaw 44 are located on the same side, so that the clamping groove of the first clamping jaw 41 and the clamping groove of the third clamping jaw 43 are in a non-parallel state, so that the first straight line direction 45 crosses the second straight line direction 46. The two groups of clamping jaw assemblies clamp two thread ends respectively, so that the two thread ends are in a cross shape, which is more convenient for subsequent splicing.

[0039] Specifically, the frame 1 includes a top plate 11, a first mounting plate 12, and a second mounting plate 13; the first mounting plate 12 and the second mounting plate 13 are respectively connected to the top plate 11, specifically, the first mounting plate 12 and the second mounting plate 13 are both connected to the first side of the top plate 11, and extend in a direction away from the first side of the top plate 11, and a certain distance is spaced between the first mounting plate 12 and the second mounting plate 13 to form a space for accommodating the wire end connection device 2. The first clamping jaw 41 and the third clamping jaw 43 are mounted on the first mounting plate 12, and the second clamping jaw 42 and the fourth clamping jaw 44 are mounted on the second mounting plate 13; the wire end connection device 2 is installed on the first side of the top plate 11 through the moving assembly 3, and the wire end connection device 2 is located between the first mounting plate 12 and the second mounting plate 13.

[0040] Specifically, the first clamping jaw 41 and the third clamping jaw 43 are movably mounted on the first mounting plate 12 along the extension direction of the first mounting plate 12; the second clamping jaw 42 and the fourth clamping jaw 44 are movably mounted on the second mounting plate 13 along the extension direction of the second mounting plate 13, so that the distance between the first clamping jaw 41 and the third clamping jaw 43 can be adjusted, and the angle formed by the intersection of the two wire ends can be adjusted.

[0041] In this embodiment, for example, the first mounting plate 12 is provided with a long slot 14 extending along the extension direction of the first mounting plate 12, and the end of the first clamping jaw 41 is provided with a connecting shaft, which passes through the long slot 14 and can move along the extension direction of the long slot 14, and the connecting shaft can be locked by a nut after passing through the long slot 14. When the nut is loosened, the position and angle of the first clamping jaw 41 can be adjusted, and the first clamping jaw 41 can be fixed after the nut is tightened. In other embodiments, other methods can also be used to achieve the movable connection between the first clamping jaw 41 and the first mounting plate 12.

[0042] Specifically, the moving assembly 3 includes a guide rail 31 and a slider 32. The guide rail 31 is installed on the first side of the top plate 11 and extends in a direction close to or away from the thread end. The slider 32 is slidably installed on the guide rail 31 along the extension direction of the guide rail 31. The thread end docking device 2 is connected to the slider 32. The slider 32 moves relative to the guide rail 31 to drive the thread end docking device 2 to move. In this embodiment, a pneumatic linear module can be selected as the moving module. In other embodiments, other structural forms such as a screw-type linear moving module can also be selected.

[0043] Specifically, in this embodiment, the thread splicing device 2 can use an air splicer, which splices the two thread ends by applying a rotating airflow to the two thread ends. The specific structure of the air splicer can be selected from the prior art and will not be described in detail in this embodiment. In other embodiments, splicers with other structural forms such as a mechanical splicer can also be selected.

[0044] Specifically, a docking identification camera 5 is also installed on the frame 1, through which the position of the thread end can be identified, thereby providing guidance for the clamping claws to clamp the thread end.

[0045] Usage: The thread connecting terminal is mounted on a mechanical arm or other mechanical structure that can drive the thread connecting terminal to move. First, the thread connecting device 2 is moved away from the clamp to reserve a certain space for the clamp to clamp the thread, and then the thread connecting terminal is driven to move according to the position of the thread and clamp the two thread ends respectively, and then the thread connecting device 2 is driven to move towards the direction close to the thread end so that the thread end enters the working area of ​​the thread connecting device 2, and finally the thread connecting device 2 is started to splice the two thread ends.

[0046] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0047] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
