Description

Technical Field

[0001] The utility model relates to the field of inductor coil winding machine accessories, in particular to a wire folding device. Background Art

[0002] After the inductor coil is wound by the winding machine, it needs to be laser welded by a spot welding machine. The inductor coil is a device that works based on the principle of electromagnetic induction. The overall shape of the coil is a spiral. According to the number of winding layers, it can be mainly divided into three types: single-layer inductor coil, double-layer inductor coil and triple-layer inductor coil.

[0003] At present, winding machines are usually used to wind inductor coils. The main process is as follows: one end of the copper wire to be wound is tied to the side wall of the winding rod, and then the motor drives the winding rod to rotate up or down, so that the copper wire is spirally wound on the winding rod. When the winding machine processes a single-layer inductor coil, the copper wire is wound around the winding rod from bottom to top or from top to bottom for one round to obtain the required single-layer inductor coil; when the winding machine processes a double-layer inductor coil, the copper wire is wound around the winding rod from bottom to top and then to bottom or from top to bottom and then to top to obtain the required double-layer inductor coil. The three-layer inductor coil is the same as the single-layer, the only difference is that the winding machine winds the copper wire two more layers.

[0004] The two lead ends of the single-layer and three-layer inductor coils obtained by the above-mentioned related technologies are respectively located at the two ends of the overall extension direction of the inductor coil. In the actual use of the inductor coil, in order to connect the lead ends of the inductor coil to the surface of the printed circuit board, the inductor coil needs to be folded before welding, so that the extension lines of the two lead ends of the inductor coil are located in the same plane of the inductor coil, avoiding the height difference between the two leads, resulting in the inability to correspond to the complete welding of the inductor coil during welding, and finally resulting in unstable welding, affecting the welding quality rate of the inductor coil.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0032] See also Figure 1-10 The figure shows a folding line device of the utility model, comprising a main support 1, a winding mechanism 2 fixed on the main support 1, and a folding line mechanism 3, the folding line mechanism 3 comprising a folding line driving unit 31 and a folding line block 32, the folding line driving unit 31 is drivingly connected to the folding line block 32, and the folding line block 32 is arranged on one side of the winding mechanism 2; the winding mechanism 2 comprises a winding driving unit 21, a winding column and a support platform 24, and the winding column is fixed on the support platform 24.

[0033] like Figure 3-Figure 5 As shown, it should be noted that the winding column includes an upper winding column 22 and a lower winding column 23, and the lower winding column 23 is fixed on a support platform 24. The diameter of the upper winding column 22 is the same as that of the lower winding column 23, and the diameter of the support platform 24 is larger than the diameter of the lower winding column 23 and the upper winding column. When working, the upper winding column 22 or the lower winding column 23 winds the copper wire to obtain an inductor 4, and the inductor 4 includes an upper lead 41 and a lower lead 42. The upper lead 41 is not in height with the lower lead 42. The folding line driving unit 31 is started so that the folding line block 32 is wound along the upper winding column 2 2 moves downward, pressing the upper end lead 41 of the inductor 4 downward to fold the feet, so that the inductor 4 of the odd number of layers is located in the same plane after the folding, so as to facilitate the use of the inductor 4. The folding mechanism 3 can fold the feet of the inductor 4 to avoid the height difference between the two leads, ensure the complete welding of the upper end lead 41 and the lower end lead 42 of the inductor 4, improve the welding stability and the quality rate, and at the same time, the folding drive unit 31 is a motor, driven by the motor, so the folding force of the folding block 32 each time can be kept consistent under the control of the motor, thereby improving the quality of the inductor 4 produced by the winding machine.

[0034] like Figure 6As shown, a first folded corner area 51 is formed at a certain position at the uppermost end of the inductor 4, and the first folded corner area 51 presses the upper end lead 41 located at the inductor 4 downward by nearly 90 degrees until a certain position of the upper end lead 41 sticks to the surface of the support platform 24; a second folded corner area 52 is formed between the upper end surface of the support platform 24 and the coil surface of the inductor 4, and the process of the lower end surface of the folding line block 32 pressing the upper end lead 41 downward causes a certain position of the upper end lead 41 to be folded in the second folded corner area 52, at which time the upper end lead 41 and the lower end lead 42 are in the same horizontal plane and in the same direction, and the upper end lead 41 is folded downward and then folded laterally under the joint action of the folding line block 32, the support platform 24 and the inductor 4 so as to be in the same horizontal plane and in the same direction as the lower end lead 42.

[0035] like Figure 7 and Figure 8 As shown, since the copper wire used for winding the inductor 4 has a layer of adhesive on its surface, the adhesive will melt when hot air is blown during winding, and the shape of the inductor 4 will be fixed when cold air is blown. However, there is no adhesive on the surface of some copper wires. In order to prevent the inductor 4 from being unshaped and spreading after winding, a wire clamping mechanism 6 is provided on the main bracket 1. The wire clamping mechanism 6 includes a wire clamping drive part 61, a wire clamping slide rail 62 and two wire clamping arms 63. The two wire clamping arms 63 have the same structure and are symmetrically arranged on the left and right. The wire clamping drive part 61 is driven and connected to the two wire clamping arms 63. The wire clamping drive part 61 is driven to make the two wire clamping arms 63 approach or move away from each other on the wire clamping rail. A wire clamping groove 64 is provided on the wire clamping arm 63. When the wire clamping grooves 64 of the two wire clamping arms 63 are close to each other, the shape of the inductor 4 can be fixed, so as to prevent the newly wound coil from spreading, avoid winding failure, and improve the winding forming efficiency of the inductor 4.

[0036] Specifically, a connecting plate 7 is provided on one side of the folding line driving part 31, and the connecting plate 7 is fixedly connected to the clamping line driving part 61. The folding line block 32 is fixedly arranged on the clamping line arm 63 and is flush with the horizontal line of the lower end surface of the clamping line groove 64. When the single-layer inductor 4 is wound on the upper winding column 22, the folding line driving part 31 is first started to drive the clamping line driving part 61, the clamping line track, the clamping line arm 63 and the folding line block 32 to move downward together. At this time, the folding line block 32 folds the upper end lead 41 at the first folding angle area 51, and then continues to fold downward at the second folding angle area 52, so that the upper end The lead wire 41 and the lower end lead wire 42 are in the same horizontal plane and in the same direction; at the same time, the wire clamping groove 64 is aligned with the outer periphery of the inductor 4, and the wire clamping driving part 61 is started so that the two wire clamping arms 63 are close to each other on the wire clamping track, and the two wire clamping grooves 64 are close to each other to squeeze and clamp the inductor 4 to shape it, and finally the wire clamping driving part 61 is started to move the two wire clamping arms 63 away from each other to release the inductor 4, and the folding line driving part 31 is started so that the wire clamping driving part 61, the wire racking track, the wire clamping arms 63 and the folding line block 32 are moved upward and reset together, and the entire folding line and shaping steps are simple, the structure is optimized, and the manufacturing cost is saved.

[0037] like Figure 3 As shown, the support platform 24 is provided with a fixed protrusion 81 and a movable clamp 82, and the main bracket 1 is provided with a pressing mechanism 9, and the pressing mechanism 9 includes a pressing driving part 91 and a pressing horizontal plate 92, and the pressing horizontal plate 92 is connected to the pressing driving part 91. The pressing driving part 91 is started to drive the pressing horizontal plate 92 to move downward, and the copper wire located above the fixed protrusion 81 and the movable clamp 82 is pressed down, so that the copper wire is located between the fixed protrusion 81 and the movable clamp 82, and then the copper wire is clamped by the movable clamp 82 close to the fixed protrusion 81. When the copper wire is wound to obtain the inductor 4, the copper wire between the fixed protrusion 81 and the movable clamp 82 is the lower end lead 42 of the inductor 4.

[0038] Working principle:

[0039] First, the copper wire is located above the fixed protrusion 81 and the movable clamp 82, the pressing driving part 91 is started, the pressing horizontal plate 92 presses the copper wire downward to between the fixed protrusion 81 and the movable clamp 82, the movable clamp 82 approaches the fixed protrusion 81 to clamp the copper wire, and the pressing horizontal plate 92 is reset;

[0040] Secondly, the winding drive unit 21 is started to wind the copper wire clockwise or counterclockwise around the outer peripheral surface of the upper winding post 22 and (or) the lower winding post 23 to obtain a single-layer inductor coil 4;

[0041] like Fig. 9As shown, the folding line driving unit 31 is started to drive the clamping line driving unit 61, the clamping line track, the clamping line arm 63 and the folding line block 32 to move downward together, and the folding line block 32 folds the upper end lead 41 at the first folding angle area 51, and then continues to fold downward at the second folding angle area 52. At this time, the upper end lead 41 and the lower end lead 42 are in the same horizontal plane and in the same direction;

[0042] like Fig.10 As shown, the wire clamping drive part 61 is started to make the two wire clamping arms 63 approach each other on the wire clamping track, and the two wire clamping grooves 64 approach each other to squeeze and clamp the inductor 4 to shape it. Then, the wire clamping drive part 61 is started to move the two wire clamping arms 63 away from each other to release the inductor 4. The wire folding drive part 31 is started to move the wire clamping drive part 61, the wire racking track, the wire clamping arms 63 and the wire folding block 32 upward and reset together.

[0043] Finally, the processed inductor coil 4 is taken away by a robot or other device to prepare for the next winding of the inductor coil 4. By repeating the above steps, single-layer coils with two leads on the same horizontal plane can be continuously obtained. The overall structure is simple, which improves the quality of the inductor coil 4 produced by the winding machine.
