Description

Technical Field

[0001] The utility model relates to the field of a wire outlet of a coil on a frame, in particular to a wire outlet mechanism. Background Art

[0002] like Figure 1-2 As shown in the figure below, this is the state of the coil after it is wound and pulled out. The purpose of pulling out the wire end is to ensure that there is enough space around the wire end to facilitate other winding mechanisms to clamp the wire end and wind it around the pins on the skeleton through the winding mechanism.

[0003] The existing thread outlet mechanism, such as patent number 202410365309.4, is named a winding foot mechanism, which includes a thread puller mechanism for pulling out the thread end.

[0004] However, the thread head mechanism (the prior art patent) that only pulls out the thread head for this purpose Figure 5-6 ), which occupies a large proportion of the entire machine. In addition, the movement range of the thread dial is also very small. If the thread dial mechanism is simplified and integrated into other mechanisms, the complexity of the structure, production cost, and production efficiency of the equipment can be significantly improved. However, the new design of the thread dial mechanism and which mechanism to combine it with have become a major problem at present. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a wire outlet mechanism, which has two functions of winding the wire and pulling the wire head. It can not only realize the winding of the copper wire on the skeleton, but also pull out the wire head on the copper wire.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A wire outlet head mechanism is characterized in that a winding groove with variable width and a mounting groove adjacent to the winding groove are provided on a winding table, a skeleton with a column is placed in the mounting groove, and the copper wire passes through the arc-shaped winding groove and spirally rises around the column at a specified radius, wherein the width of the winding groove can be changed from a state of reducing the radius of the copper wire to a state of expanding the radius of the copper wire, and the wire head is located outside the column after passing through the winding groove with a larger radius.

[0008] Furthermore, it also includes a forming part, a telescopic cylinder, and a push rod. The winding table is provided with an opening adjacent to the mounting groove, and the opening has space required for the movement of the forming part. The side wall of the forming part cooperates with the top surface of the side wall that makes the mounting groove have a groove depth to form a winding groove with variable width. The piston rod of the telescopic cylinder is connected to the forming part through the push rod.

[0009] Furthermore, in a state where the radius of the copper wire is expanded, the formed part is separated from the mounting groove due to the contraction of the telescopic cylinder.

[0010] Furthermore, the winding table is provided with a linear groove for feeding the copper wire into the winding groove.

[0011] Furthermore, it also includes a wire feeding mechanism, which includes a vertical plate, multiple groups of longitudinally distributed guide rubber wheels arranged on one side of the vertical plate, and a wire feeding motor, belt, and driven wheel located on the other side of the vertical plate. The driven wheel is coaxially connected to the guide rubber wheel, and the wire feeding motor is connected to the driven wheel through a belt.

[0012] Beneficial effects of the utility model:

[0013] The bending of the copper wire is constrained by the outer arc surface of the winding groove. When the copper wire continues to pass through the winding groove, the resistance provided by the winding groove forces the copper wire to bend along the current radius of the outer arc surface. The variable width of the winding groove causes the radius of the copper wire to change. In other words, after the wire end is bent with a larger radius, it is located outside the column, which serves the purpose of the wire end exiting. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] See also Figure 3-5 As shown, it includes two parts: a wire feeding mechanism 1 and a winding mechanism 2. The wire feeding mechanism 1 actively feeds out the copper wire 3 and pushes the copper wire 3 into the winding mechanism 2. Under the action of the winding mechanism 2, the copper wire 3 is wound on the column 41 of the skeleton 4.

[0026] like Figure 1-2 As shown, a pair of columns 41 are shown on the skeleton 4, and the copper wire 3 is wound around the above-mentioned columns 41.

[0027] The winding mechanism 2 includes:

[0028] like Figure 6-9 As shown, the winding table 21 is provided with a winding groove 22 with variable width. The winding groove 22 is arc-shaped. The copper wire 3 is initially linear. When the copper wire 3 is pushed into the winding groove 22, the copper wire 3 is constrained by the outer annular surface 22a of the winding groove 22 and bends along the radius of the outer annular surface 22a. In the case of continuous wire feeding, the copper wire 3 is wound around the column 41 in a spiral form.

[0029] The variable width of the winding groove 22 can change the radius of the copper wire 3. The wire end 31 is bent when the winding groove 22 has a larger radius, and the rest of the copper wire 3 is bent using the winding groove 22 with a minimum radius. In this way, the spiral copper wire 3 has its wire end 31 independently outside the column 41 with a larger radius. At this time, the pulling out of the wire end 31 has been completed. In other words, the means of the variable width winding groove 22 retains the original winding function and can realize the pulling out of the wire end 31. This improvement to the winding mechanism 2 simplifies the structure of the entire winding foot-wrapping mechanism. At the same time, the production cost and production efficiency can be significantly improved.

[0030] like Figure 11As shown, in this embodiment, the variable winding groove 22 is formed by a combination of a movable molded part 23 and a top surface 24a on the side wall of the mounting groove 24. The winding platform 21 is provided with an opening 21a for the movement of the molded part 23. The opening 21a is adjacent to the mounting groove 24. The linear movement of the molded part 23 in the above-mentioned opening 21a abuts against or moves away from the side wall of the mounting groove 24. In addition, the height of the molded part 23 is higher than the above-mentioned side wall. In other words, the mounting groove 24 is formed by the top surface 24a on the side wall of the mounting groove 24 and the side wall (that is, the outer annular surface 22a) of the molded part 23. The power source for implementing the movement of the molded part 23 is a combination of a telescopic cylinder 25 and a push rod 26. The telescopic cylinder 25 is connected to the molded part 23 via the push rod 26.

[0031] From a structural point of view, only one telescopic cylinder 25 is needed, and no other additional auxiliary mechanisms are required, so the structure is simple.

[0032] The steps for use are:

[0033] S1, using the telescopic cylinder 25, the molded part 23 is pulled away from the side wall of the installation groove 24 in the opening 21a, and a distance is created between the side wall of the molded part 23 and the side wall of the installation groove 24. At this time, the winding groove 22 is in a state of expanding the radius of the copper wire 3;

[0034] S2, feeding the copper wire 3. After crossing the above distance, the copper wire 3 contacts the side wall of the molded part 23 and is bent along the arc surface of the side of the molded part 23.

[0035] S3, (e.g. Figure 10 As shown in the figure, after the wire end 31 is bent, the telescopic cylinder 25 pushes the forming part 23 to move the remaining part of the copper wire 3 against the circumference of the column 41. At this time, the forming part 23 is against the side wall of the installation groove 24, and the remaining part of the copper wire 3 is spirally wound on the column 41 with a smaller radius.

[0036] In this embodiment, a base 26 is further included. The winding platform 21 is disposed on the base 26 , and the telescopic cylinder 25 is disposed on the base 26 .

[0037] The winding platform 21 is further provided with a linear groove 27 for feeding the copper wire 3 into the winding groove 22 .

[0038] It also includes a wire feeding mechanism 1, which includes a vertical plate 100, multiple groups of longitudinally distributed guide rubber wheels 101 arranged on one side of the vertical plate 100, and a wire feeding motor 102, a belt 103, and a driven wheel 104 located on the other side of the vertical plate 100. The driven wheel 104 is coaxially connected to the guide rubber wheel 101, and the wire feeding motor 102 is connected to the driven wheel 104 through the belt 103. The copper wire 3 is located between the two guide rubber wheels 101 in the same group. Under the action of the wire feeding motor 102, the copper wire 3 is pushed to move into the linear groove 21b.

[0039] The above embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
