Description

Technical Field

[0001] The utility model relates to the technical field of coil welding, in particular to a coil welding device. Background Art

[0002] Inductance is a property of a closed loop and a physical quantity. When current passes through a coil, a magnetic field is induced in the coil, and the induced magnetic field generates an induced current to resist the current passing through the coil. It is a circuit parameter that describes the induced electromotive force effect caused in the coil or in another coil due to the change of coil current. The device that provides inductance is called an inductor.

[0003] In the coil manufacturing process of inductors, there is a wire winding welding process. During welding, since the welding lead is heated at the soldering point, the lead area near the soldering point will be locally heated, thereby generating thermal stress. The lead material around the soldering point will undergo slight thermal deformation due to the temperature gradient, causing the lead to relax due to slight bending, affecting the consistency of multiple coil welding positions and causing poor welding.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-Figure 3 , Figure 5-Figure 6 As shown, the utility model provides a coil welding device, which is suitable for welding coils. The coil needs to be placed on a carrier 1 before welding. The carrier 1 is connected to an external horizontal guide rail (not shown in the figure) so that the carrier 1 can move laterally on a horizontal plane. A coil position for placing the coil is provided on the carrier 1, and a wire rack 7 is provided on the carrier 1. In the present application, the wire rack 7 is a copper sheet. The coil is placed on the carrier 1. At this time, the coil is located in a hole in the copper sheet, and the lead on the coil is located in a lead groove on the carrier 1 and the lead is in contact with the copper sheet. In addition, the carrier 1 also has a positioning hole 11.

[0027] like Figure 1 As shown, the coil welding device includes: a driving assembly, specifically, the driving assembly includes a first cylinder 3 and a second cylinder 4, the first cylinder 3 and the second cylinder 4 are both fixedly mounted on a bracket 2, the first cylinder 3 is connected to a pressing assembly 5, and the first cylinder 3 drives the pressing assembly 5 to move downward for pressing the lead wire.

[0028] Specifically, Figure 2-Figure 4 As shown, the pressing assembly 5 includes a first connecting member 51, and the first connecting member 51 is not limited to a plate-like structure, a block-like structure, or a combination of a plate-like structure and a block-like structure. The first connecting member 51 is connected to the first cylinder 3, and the first connecting member 51 is connected to an upper cover plate 52 by bolts. A plurality of first bosses 56 and a plurality of second bosses 57 are arranged at the bottom of the upper cover plate 52. The first cylinder 3 drives the first connecting member 51 and the upper cover plate 52 to move downward until the first boss 56 and the second boss 57 contact the top of the lead. At this time, the first boss 56 and the second boss 57 each form a contact point when contacting a single lead, and the welding point of the lead is located between the two contact points.

[0029] Furthermore, the first connecting member 51 is provided with a positioning pin 55 for positioning in the vertical direction, so that when the upper cover plate 52 moves downward, the positioning pin 55 can be inserted into the positioning hole 11 on the carrier 1. The first connecting member 51 also has a through hole 54, and a spring is arranged in the through hole 54. The first connecting member 51 is connected to the fixed block 53, one end of the spring is fixedly connected to the fixed block 53, and the other end of the spring is suspended.

[0030] like Figure 1 As shown, the second cylinder 4 is connected to the supporting assembly 6, and the second cylinder 4 drives the supporting assembly 6 to lift up to support the lead.

[0031] Specifically, Figure 2-Figure 3 The supporting assembly 6 includes a second connecting member 61 , and the second connecting member 61 is not limited to a plate-like structure, a block-like structure, or a combination of a plate-like structure and a block-like structure, and the second connecting member 61 is connected to the second cylinder 4 .

[0032] Furthermore, Figure 5-Figure 7 As shown, the second connecting member 61 is connected to the lower toothed block 62 by bolts, and the lower toothed block 62 is provided with a plurality of first supporting parts 63 and a plurality of second supporting parts 64. The second cylinder 4 drives the second connecting member 61 and the lower toothed block 62 to lift until the first supporting part 63 and the second supporting part 64 contact the bottom of the lead wire.
