[0029] As Figs. 1 to 3As shown, a pulling device, comprising: a guide rail 2, a moving frame 3, a first air cylinder 4, a support 5, a second air cylinder 6, a driving device 7, the moving frame 3 is slidingly arranged on the guide rail 2, the driving device 7 is connected with the moving frame 3, for driving the moving frame 3 to move; the moving frame 3 is sequentially provided with a guide roller 31, a first limiting block 32, and a second limiting block 33, the guide roller 31 is horizontally rotatably arranged on the moving frame 3, the first limiting block 32 is fixed on the moving frame 3, first guide grooves 321 are formed on both sides of the first limiting block 32, and two guide wheels 322 corresponding to the first guide grooves 321 are rotatably arranged on the first limiting block 32; the second limiting block 33 is slidingly arranged on the moving frame 3, the first air cylinder 4 is connected with the second limiting block 33, for driving the second limiting block 33 to slide, the second limiting block 33 has an accommodating opening 331, and the first limiting block 32 can enter the accommodating opening 331, so that the first limiting block 32 and the second limiting block 33 form a limiting passage for the copper wire 100 to pass through; the support 5 is fixed on the moving frame 3, the second air cylinder 6 is fixed on the support 5, a pressing block 61 is fixed on an output shaft of the second air cylinder 6, and the pressing block 61 can be pressed on the first limiting block 32 to close the upper part of the limiting passage.
[0030] In the present application, one end (free end) of the copper wire 100 has been fixed, which needs to be matched with another fixing structure 200 for use, and the other end is located on the copper wire disc 300. In this state, the part between the fixed end of the copper wire 100 and the pulling device and the part between the copper wire disc 300 and the pulling device will be straightened.
[0031] A part of the copper wire 100 in the middle is pulled out, so as to be wound on the two guide wheels 322 on the first limiting block 32, and the copper wire 100 passes through the first guide groove 321. Then, the first air cylinder 4 and the second air cylinder 6 are started, the first air cylinder 4 starts to work, drives the second limiting block 33 to move, and makes the second limiting block 33 move towards the first limiting block 32, until a part of the first limiting block 32 can be accommodated in the accommodating opening 331 of the second limiting block 33, and the inner wall of the accommodating opening 331 is used to block the outer side of the first guide groove 321. At the same time, the second air cylinder 6 drives the pressing block 61 to press down, and the pressing block 61 closes the upper part of the first guide groove 321. Through such operation, a limiting passage that cannot be separated from the copper wire 100 is formed.
[0032] The driving device 7 is connected with the moving frame 3 which is slidably arranged on the guide rail 2. When the driving device 7 is started to work, the moving frame 3 is powered to move along the guide rail 2, and the copper wire 100 passes through the guide roller 31 which is horizontally arranged on the moving frame 3. Under the action of the guide roller 31, the copper wire 100 can travel along the set route. Since one end of the copper wire 100 has been fixed in advance, the copper wire 100 is continuously drawn out from the copper wire disc 300 during the movement of the moving frame 3. In this process, the two guide wheels 322 on the first limiting block 32 play a guiding role, so that the copper wire 100 can slide more smoothly.
[0033] In the device, the first limiting block 32 and the second limiting block 33 cooperate to form a limiting channel for the copper wire 100 to pass through, through the first guide groove 321 on both sides of the first limiting block 32 and the corresponding guide wheel 322. The copper wire 100 can be constrained from multiple directions to maintain an accurate position during movement, effectively avoiding large-scale deviation or shaking, and ensuring the accuracy of the movement path of the copper wire 100.
[0034] In the above wire pulling device, the moving frame 3 is fixed with a guide block 8 on the front side, and two second guide grooves 81 perpendicular to the central axis of the guide roller 31 are formed on the guide block 8. The second guide grooves 81 are adapted to the thickness of the copper wire 100, and the first guide grooves 321 correspond to the second guide grooves 81 one by one.
[0035] The two second guide grooves 81 perpendicular to the central axis of the guide roller 31 are formed on the guide block 8, and the thickness of the copper wire 100 is adapted to the first guide grooves 321 on the first limiting block 32. The first guide grooves 321 correspond to the second guide grooves 81 one by one, which limits the copper wire 100 from multiple dimensions. Before the copper wire 100 enters the subsequent limiting channel along the guide roller 31, the copper wire 100 is accurately constrained in the direction perpendicular to the axis of the guide roller 31 through the second guide groove 81, so that the copper wire 100 maintains an accurate transverse position.
[0036] In the above wire pulling device, the guide roller 31 is rotatably arranged on the guide block 8.
[0037] In the above wire pulling device, the driving device 7 includes a driving motor 71 and a screw nut assembly 72. The driving motor 71 is connected with the screw nut assembly 72 to drive the screw in the screw nut assembly 72 to rotate. The nut in the screw nut assembly 72 is fixedly connected with the moving frame 3.
[0038] The driving motor 71 drives the screw to rotate, the screw drives the nut to move, and the nut drives the moving frame 3 to move on the guide rail 2.
[0039] In the above-described pull wire device, the moving frame 3 is further provided with an auxiliary wheel 9 rotatably arranged on one side of the extension line of one of the second guide grooves 81.
[0040] In the case that the copper wire 100 is loose between the pull wire device and the copper wire disc 300, the auxiliary wheel 9 is pressed on the copper wire 100 to avoid the copper wire 100 from being partially separated from the first guide groove 321. The auxiliary wheel 9 is pressed on the copper wire 100 from one side of the copper wire 100 to move the copper wire 100 towards the second limiting block 33.
[0041] In the above-described pull wire device, the inner wall of the accommodating opening 331 of the second limiting block 33 is provided with a ring groove 332 corresponding to the first guide groove 321, and the second limiting block 33 is fixed with a plurality of metal guide rods 333 inserted into the ring groove 332.
[0042] The metal guide rods 333 are fixed on the second limiting block 33 and inserted into the ring groove 332, which enhances the structural strength and stability of the second limiting block 33 and reduces the abrasion of the second limiting block 33 during the movement of the copper wire 100.
[0043] It should be noted that the above examples are only used to illustrate the present application and not to limit the technical solutions described in the present application. Although the present application has been described in detail with reference to the above examples, those skilled in the art should understand that the technical personnel in the technical field can still modify or equivalently replace the present application, and all technical solutions and improvements that do not deviate from the spirit and scope of the present application should be covered in the scope of the claims of the present application.
