Description

Copper wire coil structures

Technical field

The utility model is cut on thick copper especially with regard to a kind of using UV laser about a kind of copper wire coil structures Copper wire coil structures.

Background technique

Generally manufacture 40 millimeters of radio-frequency coils below of coil diameter be made of use copper wire in a manner of around spiral, and The radio-frequency coil of this size is not available made of laser machine cutting the reason is that, during being cut by laser copper material The energy for having fraction of laser light is absorbed by copper material, and is made copper material heat expansion and generated copper deformation, and then make the copper wire position being cut into And size generates apparent deviation, finally resulting in radio-frequency coil after the completion of cutting is not to be in complete helical form It is existing.

Utility model content

The main purpose of the utility model is to provide a kind of diameter is cut on 100 μm or more of thick copper is less than or equal to 40 millimeters of copper coil.

In order to achieve the above object, the utility model provides a kind of copper wire coil structures, wherein with a thickness of 100 μm or more Thick copper is equipped with connecting bridge and groove；The connecting bridge is located on thick copper and has certain width, which refers in thickness The particular block not cut through by laser beam on copper；The groove is set to the two sides of connecting bridge and is presented with the appearance of arc, The groove is cut by laser.

Wherein, the diameter of the copper coil is less than or equal to 40 millimeters.

Wherein, quantity set by the connecting bridge is more than one.

Utility model has the advantages that

1, copper coil directly is made in circle Copper fabrication using laser；

2, circle copper will not deform and generate dimensional discrepancy during cutting.

Specific embodiment

The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art The utility model can be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.

Referring initially to Fig. 1, Fig. 2 and Fig. 3, Fig. 1 is that the UV laser processing process of the utility model copper coil is shown It is intended to, Fig. 2 is the utility model copper coil structural schematic diagram, and Fig. 3 is the utility model copper coil structure partial enlarged diagram.

The UV laser processing 1 of the utility model copper coil, made through the following steps:

Positioning step 11: using fixed fixture by the thick copper 21 with a thickness of 100 μm or more be fixed to target position and by its It flattens.

Cutting step 12: the cutting of copper wire is carried out on thick copper 21 by UV laser in a manner of around spiral, and is being cut After the completion in there are not by the connecting bridge 211 of UV laser cutting and positioned at the multiple tracks groove 212 of connecting bridge two sides on thick copper 21.

Cutting step 13: connecting bridge 211 is cut off using UV laser, is connected with each other the groove 212 of 211 two sides of connecting bridge And complete spiral groove 212 together is formed, and then obtain a spiral helicine copper coil.

In addition, the utility model copper wire coil structures 2, be equipped on the thick copper 21 with a thickness of 100 μm or more connecting bridge 211 with And groove 212.

The connecting bridge 211 is located on thick copper 21 and has certain width, the connecting bridge 211 refer on thick copper 21 not by The particular block that UV was cut by laser.

The groove 212 is set to the two sides of connecting bridge 211 and with the presentation of the appearance of arc, which is swashed by UV Light is process.

It can schema shown in details are as follows for reference about the embodiments of the present invention and correlation:

It is continuous to please refer to Fig. 4 and the Fig. 2 and Fig. 3 that arranges in pairs or groups, Fig. 4 are that the UV laser processing of the utility model copper coil implements stream Journey schematic diagram.

As indicated at step 31, the thick copper 21 that will be cut first is fixed using fixed fixture, and passes through fixation simultaneously Jig is flattened, and avoids the thick copper 21 from leading to occur unnecessary error in subsequent processing because of surface irregularity whereby.

As shown at step 32, then fixed fixture is put into laser cutting machine, and allows UV laser in a manner of around spiral It is cut into a plurality of copper wire on thick copper 21, and in order to avoid copper wire position generates offset and size generates during cutting Deviation, therefore the connecting bridge 211 not cut through by UV laser more than at least one can be reserved especially on thick copper 21, so that having cut Thick copper 21 after is equipped with the groove 212 that multiple tracks does not interconnect.

And aforementioned 211 manufacturing process of connecting bridge can make laser beam that can not incite somebody to action to block laser beam using fixed fixture Energy beats the connecting bridge 211 for being formed on thick copper 21 and not cut in turn, or the operating software by setting laser cutting machine The energy of laser beam is controlled, makes the energy of its laser beam when by specific path that can not cut through thick copper 21 and forms, In addition, the form that connecting bridge 211 shapes is not only limited in shown in Fig. 2 radial, the reserved most important purpose of connecting bridge 211 exists In avoiding copper wire position from generating offset and size generation deviation, as long as therefore learning that copper wire how long is being cut by calculated in advance It cuts to be deformed and can arbitrarily adjust position set by connecting bridge 211 and quantity.

As shown in step 33, finally connecting bridge 211 is being cut off using UV laser, is making the groove 212 of 211 two sides of connecting bridge It is connected with each other, and just will form one when all grooves 212 connect into a road length groove 212 as made of the laying of spiral copper wire Copper coil.

In summary, the UV laser processing of the utility model copper coil and its structural advantages are:

The spiral that diameter is less than or equal to 40 millimeters directly is made in the thick Copper fabrication with a thickness of 100 μm or more using UV laser Copper coil.

The setting of connecting bridge can make the copper wire being cut into be kept fixed line width, and be avoided that copper material absorbs excessive laser energy It generates thermal deformation and the position of copper wire and size is caused to generate deviation.

Embodiment described above is only preferred embodiments for fully illustrating the utility model, the utility model Protection scope it is without being limited thereto.Those skilled in the art made equivalent substitute or change on the basis of the utility model It changes, both is within the protection scope of the present invention.The protection scope of the utility model is subject to claims.
