Description

Technical Field

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

[0002] Currently in the field of inductors, most manufacturers use three spot welding methods for spot welding semi-finished products with lead frames: resistance welding, laser spot welding and ultrasonic spot welding. A single spot welding method often cannot perfectly achieve the original design intention and electrical advantages of the molded product.

[0003] The existing Chinese patent with authorization announcement number CN 218638806 U discloses an inductor coil spot welding device, including a resistance welding structure, a laser welding structure and a transmission structure. The resistance welding structure includes a first support frame and a spot welding needle, the first support frame is used to support the spot welding needle, and the spot welding needle is used to weld the inductor coil and the wire; the laser welding structure includes a laser welding gun and a second support frame, the second support frame is used to support the laser welding gun, and the laser welding gun is used to perform secondary welding on the inductor coil and the wire; the transmission structure is used to pass the inductor coil and the wire through the resistance welding structure and the laser welding structure in sequence. The resistance welding structure first performs a virtual welding on the inductor coil and the wire, ensuring that the inductor coil and the wire are welded first, avoiding an excessively large welding spot area, and then improving the melting effect through laser welding. The inductor coil spot welding device in the utility model can achieve the purpose of making the welding spot between the inductor coil and the wire melt well when welding, while reducing the welding spot area.

[0004] The disadvantage of the above existing solution is that: due to the thickness of the inductor coil itself, the reciprocating stroke of the spot welding needle is affected by the thickness of the inductor coil itself. The thicker the inductor coil, the greater the reciprocating stroke of the spot welding needle, the longer the time spent, and the lower the welding efficiency. Utility Model Content

[0005] The utility model aims to provide an inductor coil spot welding device to solve the technical problem in the prior art that the reciprocating stroke of the spot welding needle is affected by the thickness of the inductor coil itself, the thicker the inductor coil, the greater the reciprocating stroke of the spot welding needle, the longer the time spent, and the technical problem of affecting the welding efficiency.

[0006] The technical problem to be solved by the utility model can be achieved through the following technical solutions:

[0007] An induction coil spot welding device, comprising:

[0009] The welding frame comprises a base, the welding frame is evenly distributed in an annular mounting frame, a placing plate 1 is fixedly connected to the base, the placing plate 1 is tiltedly arranged on the base, a placing plate 2 is fixedly connected to the placing plate 1, the placing plate 2 is horizontally arranged, the placing plate 1 and the placing plate 2 have a smooth transition, and an arc-shaped supporting plate is fixedly connected to the placing plate 1;

[0010] The resistance welding mechanism comprises two symmetrically arranged welding guns, wherein the welding guns are arranged above the connection between the first placing plate and the second placing plate.

[0011] As a further solution of the utility model: a fixing plate is fixedly connected to the lower end of the base, and the welding frame is fixedly connected to the annular mounting frame through the fixing plate.

[0012] As a further solution of the utility model: the inner arc surface of the arc-shaped supporting plate is arranged upward, and a supporting rod is fixedly connected to the arc-shaped supporting plate.

[0016] Beneficial effects of the utility model:

[0017] 1. When the utility model is in use, the inductor coil has two pins that need to be welded with the wires respectively. The inductor coil is set on the arc-shaped support plate, and the wire is clamped on the wire clamping plate.

DETAILED DESCRIPTION

[0024] 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 of 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.

[0025] like Figure 1-Figure 3 As shown, an inductive coil spot welding device includes: a mounting plate 1, a welding frame 5 and a resistance welding mechanism 2, a support frame 3 is rotatably arranged on the mounting plate 1, an annular mounting frame 4 is fixedly connected to the support frame 3, the welding frame 5 includes a base 52, the welding frame 5 is evenly distributed on the annular mounting frame 4 in a ring shape, a placement plate 1 53 is fixedly connected to the base 52, the placement plate 1 53 is tiltedly arranged on the base 52, a placement plate 2 54 is fixedly connected to the placement plate 1 53, the placement plate 2 54 is horizontally arranged, and there is a smooth transition between the placement plates 1 53 and the placement plates 2 54, an arc-shaped support plate 56 is fixedly connected to the placement plate 1 53, and the resistance welding mechanism 2 includes two symmetrically arranged welding guns 8, and the welding guns 8 are arranged above the connection between the placement plates 1 53 and the placement plates 2 54.

[0026] A fixing plate 51 is fixedly connected to the lower end of the base 52, and the welding frame 5 is fixedly connected to the annular mounting frame 4 through the fixing plate 51. The inner arc surface of the arc-shaped support plate 56 is arranged upward, and a supporting rod 57 is fixedly connected to the arc-shaped support plate 56. The supporting rod 57 is vertically arranged relative to the end surface of the arc-shaped support plate 56. A wire clamping plate 55 is fixedly connected to the placement plate 2 54, and an inductor 7 is arranged on the arc-shaped support plate 56. A wire 9 is clamped on the wire clamping plate 55, and the welding point between the inductor 7 and the wire 9 is arranged below the welding gun 8.

[0027] In some specific embodiments, the resistance welding mechanism 2 also includes a mechanism support frame 11 and an electric push rod 12. The electric push rod 12 is fixedly mounted on the mechanism support frame 11. The driving end of the electric push rod 12 is fixedly connected to the welding gun 8. The welding gun 8 is driven by the electric push rod 12 to move in a vertical position.

[0028] In some specific embodiments, the laser welding mechanism 6 includes two symmetrically arranged laser welding guns and a support frame. The two symmetrically arranged laser welding guns simultaneously weld the two pins of the inductor coil 7 and the wire 9. The resistance welding mechanism 2 performs electric welding on the inductor coil 7 and the wire 9 and then performs laser welding to improve the melting effect.

[0029] An inductor coil spot welding device also includes: a driving mechanism 10, the driving mechanism 10 is arranged below the mounting plate 1, the driving end of the driving mechanism 10 is coaxially fixedly connected to the support frame 3, the driving mechanism 10 drives the support frame 3 to rotate the same angle in sequence, so that several welding frames 5 on the annular mounting frame 4 are rotated to below the welding gun 8 in sequence, and the inductor coil 7 and the wire 9 on the welding frame 5 are welded by the welding gun 8. If 6 welding frames 5 are arranged on the annular mounting frame 4, the driving mechanism 10 drives the support frame 3 to rotate 60 degrees each time.

[0030] If the driving mechanism 10 is a grooved wheel mechanism, the grooved wheel mechanism is a unidirectional intermittent motion mechanism composed of a grooved wheel and a cylindrical pin, also known as a Malta mechanism, which is often used to convert the continuous rotation of the active member into a unidirectional periodic rotation with pauses of the driven member.

[0031] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0032] When in use, the inductor 7 has two pins that need to be welded to the wire 9 respectively. The inductor 7 is set on the arc-shaped support plate 56, and the wire 9 is clamped on the wire clamping plate 55. Since the placement plate 1 53 is tilted on the base 52, and the placement plate 1 53 is fixedly connected with the horizontal placement plate 2 54, the inductor 7 is placed on the tilted placement plate 1 53, and the welding point between the inductor 7 and the wire 9 can be set below the welding gun 8. The inductor 7 and the wire 9 are directly welded by the welding gun 8, and the reciprocating travel of the welding gun 8 will not be increased due to the height of the inductor 7, and the reciprocating time of the welding gun 8 can be shortened, thereby improving the welding efficiency.

[0033] Since the placement plate 53 is fixedly connected to an arc-shaped support plate 56 with the inner arc surface facing upward, and the arc-shaped support plate 56 is fixedly connected to a supporting rod 57, inductance coils 7 of different thicknesses can be placed on the inclined placement plate 53, thereby improving the applicability of the device.

[0034] Several embodiments of the utility model are described in detail above, but the embodiments of the utility model are not limited thereto and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
