Description

Wire package wire rack, wire winding method and wire winding device

The present invention relates to a wire package reel, a wire take-up method, and a wire take-up device, which are preferably applied to a wire body having a low proof stress characteristic with respect to a line. The frame is packaged for winding as a wire for, for example, a solar cell.

The solar cell system has a configuration in which a specific region of a germanium crystal cell as a solar cell is soldered using a wire for connection and transmitted through a wire. The wire for the solar cell is connected to the connection portion of the solar cell unit, and in order to follow the deformation amount of the solar cell unit, the value of the 0.2% proof value must be lowered. In other words, as a wire for a solar cell, it is required to have a low endurance characteristic which lowers the value of 0.2%. Therefore, it is conventionally used to use a line body (hereinafter also referred to as a low-endurance line body) which lowers its 0.2% proof value.

In recent years, in order to alleviate the influence of insufficient supply of niobium raw materials for solar cell constituent materials and to reduce material costs, solar cell units have begun to be thinner.

However, the strength of the solar cell is relatively weak after being thinned, and the connection portion of the solar cell to the wire for solar cell is also liable to cause bending or damage of the solar cell due to the difference in expansion ratio of each other.

Therefore, in order to be able to deform the solar cell unit, the connecting portion of the solar cell lead wire and the solar cell unit must have an important characteristic of lowering the 0.2% proof value.

In order to maintain the 0.2% endurance value at a lower value, the low-endurance line body must use a completely different winding assembly method for the wire frame at the time of manufacture, which generally does not reduce the 0.2% endurance value. Winding assembly.

More specifically, the wire winding method and the wire winding device for the conventional wire body which does not reduce the 0.2% proof value are disclosed in Patent Document 1 (Japanese Patent Laid-Open Publication No. 2002-241053) The wire winding method and the wire winding device proposed in the method.

The wire winding method and the wire winding device described in Patent Document 1 are provided with a pressure roller unit for pressurizing contact at the periphery of the wire body when the wire is wound up, and by a pressure roller unit The wire winding method and the wire winding device for correcting the misalignment of the winding pitch and at the same time restraining the wire body from achieving the winding efficiency of the entire row are suppressed.

By winding the assembled wire body in the above manner, the wire frame can be wound and assembled at a set value of a traverse pitch of about 1.0 times the width of the wire body. In other words, it is possible to form a wound state in which the wound layer is accumulated layer by layer, and each of the wound layers is constituted by an arrangement portion in which the wire bodies are repeatedly arranged in the direction of the wire frame axis. The arrangement of the wire body is arranged in the direction of the wire frame axis without gaps, and is in a consistent arrangement in the axial direction of each winding layer.

In the wire winding method and the wire winding device described in Patent Document 1, when the wire body is a normal wire body which is generally not low-resistance, At the same time, sufficient winding assembly tension is applied to perform winding assembly, and the periphery of the wire winding assembly layer is pressurized and assembled by the pressure roller unit, so that even if the traverse pitch is about 1.0 times the width of the wire body The length is also not affected by winding misalignment and winding slack.

However, when the low-endurance wire body is wound and assembled, the wire body cannot maintain its 0.2% endurance value at a lower value when a load is applied, so that compared with the general non-low endurance The wire body is assembled for winding, and the wire frame must be wound and assembled using a small winding assembly tension.

Further, when the wire body having low endurance is wound and assembled using the wire winding method and the wire winding device described in Patent Document 1, for example, the wire winding assembly is performed by the pressure roller unit. Pressurization of the periphery of the layer and simultaneous winding assembly can result in the problem that the wire body cannot maintain its 0.2% endurance value at a lower value under the applied load.

It is worth mentioning that if the above method is changed to pressurize the periphery of the wire winding assembly layer without using the pressure roller unit, or if the wire body is used for winding assembly using a small winding assembly tension, The lead angle of the spiral winding assembly in the direction of the wire frame axis becomes small, which causes a winding misalignment in the axial direction of the wire frame, and the winding misalignment phenomenon is also a wire winding looseness (winding collapse) or a roll. The main cause of the collapse phenomenon.

In particular, in the case of the wire winding method and the wire winding device described in Patent Document 1, the traverse pitch is set to a length of about 1.0 times the width of the wire body, that is, the wire body is in the axial direction of the frame. When the complex arrangement portion exhibits a state in which there is no gap in the entire column state, the surface of the wound layer formed by the arrangement of the plurality of arrangement portions will be slightly flat.

In this way, a plurality of layers of the wound layer are laminated in the radial direction of the wire frame, and in the wound layer in which the inner side and the outer side are adjacent to each other in the radial direction, the outer wound layer is likely to form a slightly flat surface. The inner winding layer is slid, so that the aforementioned winding slack and winding collapse phenomenon in the direction of the bobbin axis are generated.

Therefore, in the case of using a low-endurance linear body, in order to keep the 0.2% proof value at a low value, it is impossible to perform winding assembly under low winding assembly tension, and it is not possible to pass through the pressure roller unit pair. The outer circumference of the wire assembly winding layer is pressurized, especially when the traverse pitch length is about 1.0 times the width of the wire body, the above-mentioned action will cause the occurrence of winding misalignment, and it will be easy to be affected by the winding misalignment. Causes the occurrence of winding slack or winding collapse.

In the case where the winding slack occurs, the winding assembly state of the bobbin cannot be maintained, and at the same time, the frictional overlap of the wire bodies with each other is likely to occur, or the components around the bobbin collar portion are easily brought into contact with each other. The wire body is worn out, and it is difficult to ensure the quality of the wire body under the application of a load. Further, once the above-mentioned winding slack occurs, for example, when the wire body is wound up, the phenomenon that the winding is loosened due to vibration is also severed.

On the other hand, when the phenomenon of winding collapse occurs, when the wire body is drawn and taken out from the state of being wound and assembled to the wire frame, the feeding portion of the wire body interferes with the winding collapse portion, causing the wire body to be pumped. When pulling out, the phenomenon of pulling and pulling each other occurs.

When these wire bodies are drawn and taken out from the state of being wound and assembled to the wire frame, a load is applied to the wire body itself due to pulling and pulling. The line body cannot maintain its 0.2% endurance value in the range of good quality.

Further, when the wire body is drawn and taken out from the state of being wound and assembled in the wire frame, once the wire bodies are pulled and pulled by each other, the wire body may be broken, and the wire body is prevented from being smoothly taken out, so that a subsequent series of production line processes must be performed. Forced to be completely interrupted, resulting in a significant drop in productivity.

The invention provides a wire body winding wire frame, a wire body winding method and a wire body winding device, which can make a low endurance line body to be wound and assembled even without applying a load to the wire frame. The entire winding state in which the winding slack or the winding collapse does not occur can be maintained, and the line body with low endurance can be smoothly taken out and taken out from the state of being wound and assembled in the wire frame.

In order to achieve the above object, a wire package wire rack of the present invention is characterized in that a line body with low endurance is opposite to a body portion of the wire frame by a predetermined one traverse pitch from one side end of the wire frame axis direction. The other side is wound up in a row, and is wound around the other side of the bobbin axial direction in the outer side of the winding layer after the winding of the entire row, thereby traversing the roll. Wrap the line body to the radial direction of the wire frame to make a winding overlap. The wire package wire rack is characterized in that the preset traverse pitch is set to a value larger than the 1.0-fold frame interval, and is simultaneously set to prevent the wire body from generating a value of the winding bulging portion. The winding bulging portion is caused by the fact that at least a part of the line body assembled in the circumferential direction of the wire frame is protruded from the other line body in the circumferential direction of the wire frame.

In other words, the traverse pitch of the present invention is set to be 1.0 times between frames. The value other than the distance is set at the same time to prevent the line body from producing a value of the winding bulging state. The winding bulging portion is caused by the fact that at least a part of the line body assembled in the circumferential direction of the wire frame is protruded from the other line body in the circumferential direction of the wire frame.

In addition, the wire package wire frame represents a wire frame in which the wire frame body portion is wound and assembled with a low-strength line body.

The line system with low endurance is a line body whose 0.2% endurance value is less than 60 MPa in the pulling experiment, for example, a line body of a rectangular conductor for a solar cell having a flat cross section and a circular cross section.

The frame spacing of the present invention is a value corresponding to the width of the line body (1.0 times the width of the line body) in the arrangement interval in which the line bodies are arranged along the axis of the wire frame. Or, after referring to the width gap of the line body in the longitudinal direction of the line body or the gap in the axial direction of the wire frame body, the set value (+α times the width of the line body) and the value corresponding to the width of the line body are added. Value (1+α times the width of the line body).

The winding bulging portion of the present invention refers to a bulging portion which is produced by winding at least a part of the line body assembled in the circumferential direction of the wire frame from the other linear body in the circumferential direction of the wire frame. However, the present invention is not limited to the expansion of the line body assembled in at least a part of the circumferential direction of the wire frame, and the other line body in the circumferential direction of the wire frame, which is slightly bulged in the axial direction of the wire frame, or may be in the direction of the wire frame axis. The concave-convex winding bulging portion in which the concave portion and the convex portion are alternately overlapped with each other, or a portion including at least a portion of the wire frame axial direction in a direction other than the wire frame axial direction.

In addition, the winding bulging portion belongs to the above-mentioned concave portion in the axial direction of the bobbin In the case where the convex portions are alternately overlapped with each other, the linear body of the convex portion is slid and collapsed toward the concave portion while the wire frame vibrates, and the phenomenon of winding slack, winding collapse, and winding misalignment occurs, and is also the winding of the present invention. The main cause of winding slack, winding collapse, and winding misalignment occurs in the bulging portion.

The shape and size of the linear body of the present invention are not limited at all, and are preferably a rectangular line. The line body is formed by the above-mentioned pure copper-based conductor material in a rectangular line, and is subjected to immersion plating on the surface to serve as a connecting wire for connecting a specific field of the bismuth crystal unit, that is, a immersion plating line for a solar cell. .

The line body is preferably formed of a pure copper-based material. The pure copper-based material is not particularly limited to a pure copper-based conductor material having a low impurity content or a high electrical conductivity, and preferably, for example, oxygen-free copper (OFC), refined copper, dephosphorized copper or the like is substantially free of oxidation. A copper-based material having a purity of 99.9% or more.

According to the configuration described above, even if the wire body with low endurance is wound and assembled without applying a load to the wire frame, the winding state in which the winding slack or the winding collapse phenomenon does not occur can be maintained, and the line with low endurance can be maintained. The body is smoothly taken out from the state of winding assembly.

More specifically, by setting the traverse pitch P to a value larger than the 1.0-times-separation pitch, the former can ensure the interval between the winding assembly portions of the line body, as compared with the case where the traverse pitch P is set to be 1.0 times the frame spacing. The winding assembly state in which the surface of the wound layer is formed into an uneven shape enhances the effect of resisting frictional resistance between the wound layers.

According to the above configuration, even if the line body is wound and assembled with a low-wound assembly tension that does not apply a load to the line body, the line body with low endurance can be obtained. The winding assembly is performed with respect to the wire frame without causing winding misalignment and winding collapse, so that a winding state in which the low endurance line body is wound and assembled can be realized.

In addition, when the traverse pitch P is set to be larger than the value of the 1.0-times-separation pitch, as described above, the low-resistance line can be wound without being wound and wound without applying the winding assembly tension. The winding assembly is disintegrated with respect to the wire frame, but on the other hand, in the case where the traverse pitch P is set, at least a part of the circumferential direction of the wire frame is generated in the circumferential direction due to the difference in the value of the traverse pitch P. Part of the more prominent winding bulging part.

In order to prevent the above, the present invention is such that by setting the traverse pitch P to prevent at least a part of the line body in the circumferential direction of the wire frame from protruding from other line bodies in the circumferential direction of the wire frame, the line body is caused to roll. The value of the bulging portion is thereby prevented from causing the main cause of the occurrence of the winding bulging portion due to the winding collapse or the winding collapse.

Therefore, the winding state in which the winding slack or the winding collapse phenomenon does not occur can be maintained, and the line body with low endurance can be smoothly taken out from the state of winding assembly.

In the embodiment of the present invention, the traverse pitch is P, and the freeze pitch is p, which is set to satisfy the condition of 1.0 × p < P < 3.0 × p.

As described above, by setting the traverse pitch P to a value satisfying 1.0 × p < P, the above-described setting is, for example, a value satisfying 1.0 × p > P, and at this time, the line body wound by the entire row is arranged along the wire frame axis direction. In the plurality of winding assembly portions formed, there is no inclination in which the winding assembly portion is overlapped with the adjacent overlapping winding assembly portions, so that the winding assembly can be performed in a stable package state.

Or, as described above, by setting the traverse pitch P to a value of 1.0 × p < P, for example, in the case of setting P = 1.0 × p, the line body assembled for the multiple layers of the wire frame is Since the alignment is almost seamless, it is possible to prevent the occurrence of a winding state in which the frictional resistance between the wound layers is low, and to avoid occurrence of winding misalignment and winding collapse.

Therefore, in the case where the winding misalignment and the winding disintegration do not occur, in addition to being able to smoothly extract the wire from the wire frame, it is possible to prevent the occurrence of skewing of the linear body and to avoid the 0.2% endurance value becoming large. Therefore, it is possible to ensure that the wire body is excellent in usable as a connecting wire for a solar cell.

Further, similarly, as described above, by setting the traverse pitch P to a value of P < 3.0 × p, it is possible to prevent the inclination of the wire body assembled to the wire frame from the wire frame axis direction (relative to the wire frame axis direction). The spiral angle of the vertical direction becomes larger. That is, the winding assembly rail of the line body with respect to the bobbin can be suppressed to a winding assembly rail having a small spiral guide angle.

In the above manner, even if the line body is wound and assembled using the low tension on the wire frame, the winding slack with respect to the wire frame does not occur, and the occurrence of the winding collapse phenomenon due to the influence of the winding misalignment can be avoided.

In addition, the aforementioned low tension means a tension lower than the tension at which the 0.2% proof force value of the low endurance resistant body is 60 MPa or less.

Furthermore, when the wire body is wound and assembled with respect to the wire frame, in addition to suppressing the load applied to the wire body, it is possible to prevent bending, bending, dents, and lines from being formed on the wire body assembled with respect to the wire frame. The occurrence of deformation phenomena such as body corner depression.

Moreover, in the embodiment of the present invention, it can be set to satisfy 1.0×p. <P < 2.0 × p and 2.0 × p < P < 3.0 × p.

In other words, it is equivalent to setting the traverse pitch P to a value other than the stop pitch p of 2.0 times.

By setting the traverse pitch P to a value other than 2.0 times the stop pitch, it is possible to prevent the winding body from being wound up in a state in which the wire body assembled and wound on the wire frame is less likely to be formed in a concavo-convex winding bulging portion. The wound state is wound assembly.

Then, the drawn portion that is taken up and taken out by the wire body assembled and assembled to the wire frame is covered by the portion where the wound bulging portion is wound and disintegrated, so that the linear body of the drawn portion and the linear body of the wound bulging portion interfere with each other. Therefore, the drawn part is not pulled and pulled by the line body during the process of pumping out, and the line body can be pumped out without applying load to the wire frame.

Therefore, when the line body is taken out with respect to the wire rack, an excessive load is not applied to the line body, and thus it is ensured that it has a low 0.2% proof value.

Further, in the embodiment of the present invention, the traverse pitch P may be set to a condition that satisfies P < 1.5 × p.

According to the above configuration, for example, when P>1.5×p, that is, when the traverse pitch P is large, the line body is likely to be in the axial direction of the frame, and the traverse pitch P is shorter than the winding assembly track. The slid in the direction causes a winding misalignment. However, if the traverse pitch P is set to P < 1.5 × p, the occurrence of the above-described situation can be prevented, and the wire package bobbin can be configured in a preferable winding state.

Furthermore, when the line body is traversed with respect to the wire frame, it is possible to surely prevent the tension from being applied by allowing the line body to be aligned in the direction of the wire frame axis. Large, winding misalignment or the application of unnecessary load on the line body.

Furthermore, when the traverse pitch P is set to P<1.5×p, when the line body of the same length is wound and assembled with respect to the bobbin, the traverse pitch P is set to P>1.5×p. In comparison, the wire frame can be wound and assembled without protruding, and a compact wire package wire frame can be constructed.

In addition, the wire package reel of the present invention is characterized in that the line body with low endurance is opposite to the body portion of the wire frame by one side of the wire frame axis direction to the other at a predetermined traverse pitch. The side ends are wound in a row, and are wound around the other side of the wound bobbin in the entire row, and are repeatedly wound from the other end of the bobbin axial direction toward the side end, thereby traversing the line to make the line The body is wound to overlap in the radial direction of the wire frame. The wire winding reel is characterized in that the traverse winding system juxtaposes the spanning portions in the winding layer along the line body axis direction to form an axial direction crossing line in the winding layer, wherein the winding layer is in the radial direction of the wire frame The outer side and the inner side are adjacent to each other, and the spanning portion is formed by the arrangement portion of the line body constituting the outer winding layer across the arrangement portion of the line body constituting the inner winding layer. Further, the predetermined traverse pitch is set to a value in which the axial direction jumper is dispersed in the winding layer in the circumferential direction of the bobbin in a range satisfying 1.0 × p < P < 1.5 × p.

According to the configuration described above, even in the case of the low-strength line body, the winding assembly can be performed without causing the winding slack without applying an excessive load, and at the same time, the occurrence of the winding bulging portion can be prevented, and the roll can be prevented from being produced. Winding pattern around collapse and winding slack.

More specifically, in the case of a normal line body which is generally not low-resistance, it is possible to traverse the wire frame while applying tension to it. Since it is assembled, even if the traverse pitch is set to P = 1.0 × p for traverse winding, the winding slack caused by the low frictional resistance between the wound layers can be minimized. Further, by traversing the traverse pitch to P = 1.0 × p, the gap between the arrangement portions of the line body along the wire frame axis direction is also small, and the aforementioned traverse portion in the wire frame axis direction is also relatively There will be no protruding (convex) portions other than the spanning portion.

On the other hand, in the case of a low endurance line body, in order to apply tension without causing winding collapse to the line body, it is necessary to set the traverse pitch P to be greater than 1.0 times the frame spacing p as described above. Value.

It is worth mentioning that, when the winding of the plurality of layers is overlapped by the traverse winding, the spanning portions are juxtaposed along the bobbin axis direction, and the winding directions are formed in the respective winding layers.

However, when the traverse pitch P is set to a value greater than 1.0 times the cue spacing p, especially in the case where the axial direction spans on each of the wound layers with a winding state consistent with the circumferential direction of the bobbin, this winding state The cross-line in the direction of the middle axis of the sample has a portion corresponding to the circumferential direction of the bobbin on each of the wound layers, and will be a protruding bulging portion of the line body as compared with other portions in the circumferential direction of the bobbin, that is, it is easy to produce a roll. Winding pattern around collapse.

Therefore, by setting the traverse pitch within a range of 1.0 × p < P < 1.5 × p, the value of the axial direction jumper in the circumferential direction of the bobbin in each of the wound layers is set, even if low endurance is used. The linear body can also be wound and assembled without causing a looseness of the load without applying an excessive load, and at the same time, the occurrence of the winding bulging portion can be prevented, and a roll that does not cause winding collapse and winding slack can be realized. Around the scene.

Here, the spanning portion is an arrangement portion of the line body constituting the outer portion of the wound layer, which is generated across the aligned portion of the line body constituting the inner portion of the wound layer.

In detail, in the entangled winding, in the wound layer in which the plurality of layers are wound and overlapped with respect to the wire frame, the wound layer in which the outer side of the wire frame is adjacent to the inner side in the radial direction of the wire frame constitutes the outer winding. The arrangement of the line bodies of the layers, or the arrangement of the line bodies constituting the inner winding layer, are all arranged in a spiral shape. On the other hand, the spiral guide angles indicating the arrangement directions of the respective arrangement portions are just positive and negative in the arrangement portion of the line body constituting the outer winding layer and the arrangement portion of the line body constituting the inner winding layer.

Therefore, when the plurality of layers are wound and overlapped with respect to the bobbin under the traverse winding, the line body constituting the outer winding layer among the plurality of winding layers is arranged to span the line body constituting the inner winding layer. The arrangement portion, and thus the arrangement portion of the line body constituting the outer winding layer, will inevitably become a spanning portion of the line portion constituting the inner winding layer, and the aforementioned crossing portion is the above-mentioned span portion.

Further, the description in the axial direction of the bobbin is not limited to be parallel to the bobbin axis direction, and may be an oblique direction with respect to the bobbin axis direction, but at least includes a direction component related to the bobbin axis direction.

Moreover, the wire package reel of the present invention is characterized in that the line body with low endurance is opposite to the body portion of the wire frame by one side of the wire frame axis direction to the other by a predetermined traverse pitch. The side ends are wound in a row, and are wound around the other side of the wound bobbin in the entire row, and are repeatedly wound from the other end of the bobbin axial direction toward the side end, thereby traversing the line to make the line The radius of the body to the wire frame Do the winding overlap. The wire winding reel is characterized in that the traverse winding system juxtaposes the spanning portions in the winding layer along the line body axis direction to form an axial direction crossing line in the winding layer, wherein the winding layer is in the radial direction of the wire frame The outer side and the inner side are adjacent to each other, and the spanning portion is formed by the arrangement portion of the line body constituting the outer winding layer across the arrangement portion of the line body constituting the inner winding layer. Further, the predetermined traverse pitch is set to a value in which the axial direction jumper is dispersed in the winding layer in the circumferential direction of the bobbin in a range satisfying 1.0 × p < P < 1.5 × p.

Moreover, the wire winding method of the present invention is characterized in that the line body with low endurance is opposite to the body portion of the wire frame by a predetermined one traverse pitch from one side end of the wire frame axis direction to the other side. The end is wound in a row, and is wound around the other side of the bobbin axial direction on the outer side of the winding layer after the winding of the entire row, and the traverse winding is used to make the line body Winding overlaps in the radial direction of the wire frame. The wire winding method is characterized in that the preset traverse pitch is set to a value larger than the 1.0 times the frame spacing, and is simultaneously set to prevent the line body from generating a value of the winding bulging portion, wherein the winding bulge The part is caused by the fact that at least a part of the line body assembled in the circumferential direction of the wire frame is protruded from the other line body in the circumferential direction of the wire frame.

Moreover, the wire winding method of the present invention is characterized in that the line body with low endurance is opposite to the body portion of the wire frame by a predetermined one traverse pitch from one side end of the wire frame axis direction to the other side.

2 is a schematic explanatory view of the winding means 71, and FIG. 3 is a schematic explanatory view of the traverse type winding unit 80 which the winding means 71 has.

The winding means 71 is constituted by a traverse type winding unit 80 and a supply unit 90, and the supply unit 90 supplies the immersion plating line 1b to the traverse type winding unit 80 on the upstream side of the traverse type winding unit 80.

The supply unit 90 is composed of a plurality of guide rollers 91 (91a, 91b, 91c, 91d, 91e) and a pull-up winch 92, wherein the guide rollers 91 are used for traversing the immersion plating line 1b.

Further, the supply unit 90 may also adjust the tension applied to the dip plating line 1b as the swinging roller of the take-up tension adjusting machine when the dip plating line 1b is pulled.

The pull-up winch 92 is provided with a motor (not shown), and is actively rotated by the motor to determine the running speed of the immersion plating line 1b (to-be-plated line 1a) from the immersion plating treatment means 2 to the immersion plating means 61.

Further, the pull-up winch 92 is pulled and pulled in the downstream direction while the immersion plating wire 1b is being pulled, and the immersion plating wire 1b is supplied to the traverse type winding unit 80.

As shown in FIG. 3, the traverse type winding unit 80 is a control unit, a bobbin turning means 110 for rotating the bobbin 200 in a pivoting manner, and a reciprocating movement for reciprocating the bobbin 200 in the direction of the bobbin axis. The means 120 is configured such that the immersion plating line 1b is wound in a row from one side of the bobbin axial direction to the other side, and the outer side of the winding assembly layer of the entire winding is repeatedly passed by the bobbin axis direction. The traverse winding of one side end to the other side is wound to form a immersion plating in which the immersion plating line 1b is wound in the radial direction of the wire frame. Wire reel rack 10.

Although not shown in the figure, the control unit rotates the bobbin 200 while rotating the shaft by the bobbin turning means 110, and repeats the reciprocating motion of the bobbin 200 in the axial direction by the reciprocating means 120. The immersion plating line 1b which has low endurance is controlled to traverse the bobbin main body portion 201 at a predetermined traverse pitch.

The bobbin turning means 110 is constituted by the take-up driving portion 111, the take-up shaft 112, and the support table 113. The winding drive unit 111 rotates the wire frame 200 in an axial direction, and the winding shaft 112 serves as a power transmission means for transmitting the rotation of the winding drive unit 111 in the direction of the wire frame 200, and the support table 113 is rotatably The take-up shaft 112 is supported.

Further, the front end portion of the take-up shaft 112 has a bobbin assembly portion 112a for accommodating the assembly bobbin 200, wherein the bobbin axial direction of the bobbin 200 coincides with the axial direction of the guide roller 91e disposed at the upstream end.

According to the above configuration, the bobbin 200 can perform only a stroke amount reciprocating motion corresponding to the length of each bobbin turning means 110 in the bobbin axial direction.

Moreover, the reciprocating means 120 is preferably at a corresponding position of the end of the bobbin body at which the screw shaft 121 corresponds to the length of the bobbin body portion 201. An end portion reaching the detecting sensor 124 (see FIG. 3) capable of detecting that the reciprocating movable portion 122 reaches the corresponding position of the end portion of the bobbin body is provided.

Next, a method of manufacturing a solder wire using the solder wire manufacturing machine 11 having the above configuration will be described.

The manufacturing method of the plating wire is composed of a pre-dip plating process and a winding process, wherein the pre-dip processing process is a step of applying the pre-plating treatment to the plating line 1a, and the winding process is treated. The surface of the plating line 1a is subjected to a solder plating process to produce a immersion plating line 1b, and a step of winding the immersion plating line 1b between the immersion plating pretreatment process and the progress program.

The pre-dip coating process is a procedure in which a heat treatment process, an acid washing process, a water washing process, and a softening annealing process are sequentially performed.

The heat treatment procedure is a procedure in which the surface of the plating wire 1a is subjected to steam cleaning by operating the inside of the heat treatment furnace 22 which is a vapor atmosphere through the to-be-plated wire 1a. By the vapor cleaning, the water-soluble lubricant or other impurities adhering to the surface of the wire 1a to be plated can be separated from the surface thereof, and the water-soluble lubricant or other impurities adhering to the surface of the wire 1a to be plated can be easily removed.

The wire 1a to be plated after the heat treatment furnace 22 is heated is cooled to a predetermined temperature by the cooling water stored in the inside of the cooling water tank 23 after passing through the connection pipe 24.

The acid washing process is performed by pickling the surface of the wire 1a to be plated which is run in the acid-based cleaning liquid 32 stored in the acid cleaning tank 31 to be plated.

In the water washing process. The surface of the wire to be plated 1a is washed with ultrasonic water in the ultrasonic cleaning tank 41, and the water soluble on the surface of the wire 1a to be plated is removed. Sexual lubricants or other impurities.

In the softening annealing process, the wire 1a to be plated is operated inside a softening annealing furnace 51 which is filled with a reducing gas and heated to 800 ° C, and the plating wire 1a is subjected to soft annealing to low endurance while being reduced. A procedure for plating the surface oxide layer of the wire 1a.

In the subsequent immersion plating process, the molten tin is adhered to the surface of the wire 1a to be plated by operating the molten immersion plating liquid 63 stored in the molten immersion plating tank 62.

The wire 1a to be plated guided from the inside of the softening annealing furnace 51 is guided to be immersed in the molten immersion plating liquid 63.

The wire 1a to be plated to be immersed in the molten immersion plating liquid 63 has a molten immersion plating liquid 63 adhered to the surface thereof, and the immersion plating line 1b which is covered with the molten immersion plating liquid 63 as a whole surface. The immersion plating line 1b is passed through the groove-in-direction direction changing roller 64 in the molten immersion plating tank 62 during the operation of the immersion plating tank 62, and is switched to the direction of the operation in the molten immersion plating tank 62. Vertically above, it is led upward by the molten dip soldering groove 62.

The dip plating line 1b is led out by the molten dip soldering groove 62, and is direction-converted by the groove up direction switching roller 65 to be operated in the side of the winding means 71.

As shown in FIG. 2 and FIG. 3, after the to-be-plated line 1a is performed by the above-mentioned immersion plating process and the immersion plating process, the processed immersion plating line 1b is utilized by the supply unit 90 in the winding means 71. The pull-up winch 92 is pulled and pulled out through the traversing take-up unit 80 on the wire rack 200.

In detail, in the winding assembly process, it can be changed appropriately The reciprocating movement means 120 arbitrarily sets the traverse pitch of the immersion plating line 1b traversely wound on the bobbin main body portion 201 by the speed or moment of the reciprocating movement driving portion (motor) 123.

Further, in the winding program, the traverse pitch is set to a value larger than 1.0 times the pitch of the fixed grid, and at the same time, it is set to prevent the immersion plating line 1b from generating a value of the bulging portion, and under this condition, the immersion is performed. The plating line 1b is tangentially wound around the bobbin main body portion 201. The winding bulging portion is caused by the fact that at least a part of the immersion plating line 1b wound in the circumferential direction of the wire frame protrudes from the other immersion plating line 1b in the circumferential direction of the wire frame.

In other words, when the traverse pitch is further P and the stop interval is other p, the traverse pitch P is set to satisfy 1.0 × p < P < 2.0 × p and 2.0 × p < P < 3.0 × p.

Corresponding to the value of the traverse pitch P is set to be in the range of 1.0 × p < P < 3.0 × p, and is a value other than the stop pitch p of 2.0 times.

Further, in the winding program, the reciprocating portion 122 sets the moving speed of the screw shaft 121 to approximately constant speed. Therefore, the bobbin 200 is wound around the bobbin main body portion 201 and the bobbin main body portion is bounded by the bobbin main body portion. The one side end of the 201 axial direction is the other end, or the movement of the other side end to the side end, and the dip plating line 1b is wound and assembled while moving slightly in the direction of the wire frame axis.

Further, the reciprocating movable portion 122 may be moved at a small interval at a predetermined traverse pitch in the direction of the bobbin axis, or may be intermittently moved intermittently, but set at a slightly constant speed as the above-described transmissive moving speed. When the wire rack 200 is wound in a whole row at a predetermined traverse pitch, it can also be lightened at the same time. The wire frame 200 is applied to the load of the low endurance immersion plating line 1b by repeated acceleration and deceleration.

The above-described plating wire manufacturing apparatus 11 and the manufacturing method can obtain various functions and effects as follows.

The plating wire manufacturing apparatus 11 is a supply device 12, a heat treatment furnace 22, an acid cleaning tank 31, an ultrasonic water washing tank 41, a softening annealing furnace 51, and a immersion plating means 61 as the pre-dip plating treatment means 2. The molten immersion plating tank 62 and the winding means 71 are arranged in series in the above-described order from the upstream side to the downstream side in the running direction of the immersion plating line 1b.

By continuously arranging the various mechanisms and continuously applying the respective procedural steps, it is possible to prevent the immersion plating line 1b having low endurance from running an unnecessary distance during the manufacturing process, and to reduce the immersion plating line 1b from being subjected to the operation. load.

Therefore, the immersion plating line 1b having a sufficiently low endurance value and a desired quality of 0.2% of the endurance value can be stably obtained, and the stability of the product and the manufacturing efficiency can be simultaneously improved by the stability of the immersion plating line 1b.

Further, in the winding device 11 and the winding program described above, the value of the preset traverse pitch P of the immersion plating line 1b with respect to the bobbin main body portion 201 is set to be larger than 1.0 times the stop spacing p. The numerical value and the value of the immersion plating line 1b are traversed with respect to the bobbin main body 201 at a value which is set to prevent the immersion plating line 1b from generating a bulging portion. The winding bulging portion is caused by the fact that at least a part of the immersion plating line 1b wound in the circumferential direction of the wire frame protrudes from the other immersion plating line 1b in the circumferential direction of the wire frame.

According to the above configuration, the influence of the immersion plating line 1b due to the winding misalignment can be greatly reduced, and at the same time, the occurrence of the winding collapse or the winding slack can be prevented. Health.

In detail, in order to keep the 0.2% proof value of the dip plating line 1b at a low value, the dip plating line 1b must be wound and assembled on the wire frame 200 at a lower tension, and in this use, When the low-tension is wound and assembled to the wire frame 200, the so-called winding slack and winding misalignment are remarkably likely to occur.

For example, when the preset value of the traverse pitch P is set to 1.0 times the fixed grid pitch, compared with the case where the preset value of the traverse pitch P is set to a value larger than the 1.0-fold stop pitch, since the wire frame axis direction is The gap between the arrangement portions of the dip plating line 1b is reduced, so that the gap between the arrangement portions of the dip plating line 1b hardly exists on the surface of the wound layer formed by the arrangement of the plurality of arrangement portions. The unevenness caused by the influence of the gap is alleviated and formed into a slightly flat shape.

In the case where the dip plating line 1b is a rectangular line, the surface of the wound layer formed by the plurality of rows of immersion plating lines 1b is disposed in the direction of the bobbin axis, and is particularly considered to be a smooth surface having a small amount of frictional resistance.

However, when the immersion plating line 1b with low endurance is generally traversed to the wire frame 200, in order to reduce the burden of the immersion plating line 1b with low endurance, a common immersion plating line which is generally not low-resistance is used. The lower winding tension traverses the wire frame 200.

As described above, when the dip plating line 1b is wound and overlapped with the wire frame 200, as the plurality of laminated winding layers are accumulated, the immersion plating line 1b constituting the wound layer causes problems such as winding slack and winding collapse.

In contrast, by setting the traverse pitch P to 1.0 than the fixed cell spacing When the numerical value is larger than that in the case where the distance is set to 1.0 times, the interval between the arrangement portions of the dip plating line 1b can be ensured, and the surface of the wound layer can be wound and assembled in a suitable uneven shape. Friction resistance between the wound layers.

According to the above configuration, the influence of the immersion plating line 1b due to the winding misalignment can be greatly reduced, and at the same time, the occurrence of winding collapse or winding slack can be prevented.

Further, as described above, when the traverse pitch P is set to be larger than the value of the 1.0-fold stop pitch, the experience is traversed in the circumferential direction of the wire frame in which the immersion plating line 1b is wound according to the set traverse pitch P. Tell us that there will be at least a part of the dip-plating line that is more prominent than the other parts in the circumferential direction, that is, the phenomenon of winding and bulging occurs. Here, even if the traverse pitch P is set to a value smaller than the 1.0-times-separation pitch, by setting it to a value at which the bulging portion does not occur, the roll in which the winding collapse or the winding collapse hardly occurs can be maintained. Around the scene.

More specifically, the winding bulging portion is generated corresponding to the set value of the traverse pitch P. For example, the different traverse pitch P interferes with the arrangement portion of the immersion plating line 1b arranged along the bobbin axis direction, and becomes a winding assembly. One of the various causes of the phenomenon of winding up and down.

When the phenomenon of winding the bulging portion occurs, the immersion plating line 1b is easily pulled from each other when being taken out from the bobbin 200, and winding collapse is also likely to occur. After the occurrence of the winding collapse, the winding collapse portion covers the pumping take-out portion and interferes, so that it is easier to pull each other when the immersion plating wire 1b is taken out from the wire frame 200.

Therefore, how to appropriately set the value of the traverse pitch P to avoid the phenomenon of winding bulging becomes quite important.

On the other hand, by setting the traverse pitch P to a value for preventing the entangled portion of the immersion plating line 1b from being generated, under these conditions, it is possible to stably wind and assemble without causing winding disturbance, and thus it is less likely to occur. Winding collapse phenomenon. The winding bulging portion is caused by the fact that at least a part of the immersion plating line 1b wound in the circumferential direction of the wire frame protrudes from the other immersion plating line 1b in the circumferential direction of the wire frame.

Therefore, when the immersion plating line 1b is taken out by the winding assembly state of the wire frame 200, since the taken-out portion of the immersion plating line 1b does not interfere with the winding collapse portion, there is no pulling phenomenon, and the immersion phenomenon can be prevented. The plating wire 1b is taken out from the wire rack 200 under a load.

Further, when the dip plating line 1b is taken out by the winding assembly state of the wire frame 200, since the excessive load can be applied to the dip plating line 1b, the immersion plating line 1b does not have a trapping phenomenon, and at the same time, The 0.2% proof value of the immersion plating line 1b is ensured to be in a lower quality range.

Further, when the immersion plating line 1b is sucked and taken out by the winding assembly state of the wire frame 200, the problem that the immersion plating line 1b is pulled out by the drawing portion and the winding collapse portion of the immersion plating line 1b is interrupted. After the interference between the extracted portion of the immersion plating line 1b and the wound collapse portion is eliminated, the procedure for exchanging the other wire frame 200 can be saved, and the production efficiency of the solar battery can be improved.

Further, in the above-described winding program, the traverse pitch is P, the frame spacing is p, and the winding operation is performed under the condition that 1.0 × p < P < 3.0 × p is satisfied.

According to the above conditions, by setting the traverse pitch to a range of 1.0 × p < P, the dip plating line 1b can be wound and assembled in a stable package state without applying a load to the wire frame 200. The dip plating line 1b can also be taken out smoothly from the wire rack 200.

Specifically, when the traverse pitch P is less than 1.0 times the cue spacing p, the dip plating line 1b is wound and assembled at a traverse pitch P in the bobbin axis direction, and the dip plating line 1b is wound and assembled. In the arrangement portion of the bobbin 200, the arrangement portion in which the bobbins are adjacent to each other in the axial direction of the bobbin has a possibility that one of the portions is overlapped and tilted toward the other portions. On the other hand, in the arrangement portion arranged in the inclined state, when the immersion plating line 1b is further overlapped on the outer layer, an unstable winding assembly state such as winding bulging and winding collapse occurs.

In the case of the above-described winding assembly, in addition to obstructing the immersion plating line 1b from being smoothly taken out, a warp bending is generated on the immersion plating line 1b, resulting in a value of 0.2% proof value becoming large, so that the immersion plating line 1b It will become quite difficult to ensure that the quality is maintained within the range in which the connecting wires for solar cells can be used.

Therefore, the traverse pitch P must be set within a range of 1.0 × p < P.

It is worth mentioning that, as described above, if the traverse pitch P is set within the range of P < 3.0 × p, even the low-endurance immersion plating line 1b is wound with a low tension to the wire frame 200. In the assembly, it is also possible to prevent the immersion plating line 1b from being wound misalignment, winding slack, and winding collapse in the axial direction of the bobbin.

More specifically, the low-endurance immersion plating line 1b is wound and assembled. In the case of the wire frame 200, the wire is assembled by applying a low tension to the dip plating line 1b, so that the load applied to the dip plating line 1b can be suppressed.

It is worth mentioning that, in the case where the traverse pitch P is set to 1.0 times the frame spacing p, the gap between the arrangement portions of the immersion plating line 1b will hardly exist, so that the wound layers are easily slid with each other, causing the winding to collapse. The production. Therefore, it is necessary to set the traverse pitch P to a value larger than the 1.0-times-separation pitch p to ensure an appropriate frictional force between the wound layers and to prevent the occurrence of the above-described winding collapse phenomenon.

On the other hand, however, as the traverse pitch P becomes larger, the immersion plating wire 1b assembled to the wire frame 200 in a direction perpendicular to the direction of the wire frame axis will become a large spiral winding. Assemble the track. In other words, the wire yoke 200 is spirally wound around the assembled immersion plating line 1b, and its inclination angle with respect to the wire frame axis direction also becomes small.

In this way, the immersion plating line 1b assembled to the wire frame 200, the winding assembly track of the immersion plating line 1b in the direction of the wire frame axis will be relatively short in the direction of the spiral lead angle, that is, the angle of the spiral lead angle will be relatively small. The change of the direction makes the dip-plating line 1b, in addition to the excessive dislocation of the self-restoring force, in addition to the easy occurrence of winding misalignment, and the degree of winding slack caused by the winding misalignment is more serious.

Further, when the traverse pitch P is set to a value equal to or greater than 3.0 times the pitch of the grid, the lead angle in the vertical direction with respect to the bobbin 200 is increased by a large spiral, so that the immersion plating line 1b must be routed to the bobbin. The wire frame 200 is wound and assembled in a pulling manner in the axial direction, which causes a problem that the load applied to the dip plating line 1b is excessively large.

Further, if the traverse pitch P is set to be greater than 3.0 times between the freeze spaces When the wire frame 200 is wound and assembled by the dip plating line 1b at a value equal to or greater than p, the immersion plating line 1b is likely to be deformed such as bending, bending dents, and corner depressions.

On the other hand, by setting the traverse pitch P to a value smaller than or equal to 3.0 times the cue spacing p, even if the bobbin 200 is wound and assembled to the bobbin 200 with a low tension, the bobbin 200 can be prevented from being wound. The phenomenon of winding misalignment, winding slack, and winding collapse occurs.

Further, when winding the wire frame 200, it is not necessary to apply the winding assembly tension to the wiring of the dip line 1b with respect to the wire frame axis direction, so that the load applied to the dip plating line 1b can be suppressed. Further, the lead angle on the wire frame 200 does not exhibit a large spiral wound state, and the occurrence of deformation such as bending, bending dents, and corner depression can be prevented from occurring in the immersion plating line 1b.

Further, in the winding method of the dip plating line 1b of the present embodiment, the low-endurance dip plating line 1b is opposed to the wire frame 200 by a predetermined one traverse pitch from the side of the wire frame axis direction. The end is wound in a row along the other side, and is wound around the other side of the bobbin axial direction in the outer side of the winding layer after the winding of the entire row, thereby traversing In the wound layer in which the outer side of the wire frame is adjacent to the inner side in the radial direction of the wire frame, the arrangement portion of the immersion plating line 1b constituting the outer wound layer crosses the arrangement portion of the immersion plating line 1b constituting the inner wound layer. The axial direction cross-line is formed on each of the wound layers in parallel along the line axis direction.

Therefore, it is necessary to set the traverse pitch P to a value in which the axial direction jumper is dispersed in the circumferential direction of the bobbin in each of the wound layers in a range satisfying 1.0 × p < P < 1.5 × p.

In other words, by setting the traverse pitch P to a value other than the stop pitch p of 2.0 times, the occurrence of the concavo-convex winding bulging portion 133 mentioned later can be avoided.

Regarding this part, use FIG. 4 to FIG. 7 for explanation.

4(a) and 4(b) are immersion plating wire reel 10 in which the immersion plating line 1b is wound and assembled in the bobbin axial direction when the traverse pitch P is set to 2.0 times the citch pitch p. The mode is shown in an expanded view.

6(a) and 6(b) show the mode of the immersion plating wire reel 10 in which the immersion plating line 1b is wound and assembled in the bobbin axis direction when the traverse pitch P is set to 2.5 times the citch pitch p. Indicate the expanded view.

4(a) and (b) and FIGS. 6(a) and 6(b), in order to achieve simplification of expression, the number of windings is also eliminated while the gap between the immersion plating lines 1b and the thickness of the immersion plating line 1b are omitted. Only the (n-1)th, nth, and (n+1)th layers are simply illustrated.

In Fig. 4(a) and Fig. 6(a), in the winding layer in which a plurality of layers are accumulated, the n-th alignment portion in which the dip-plating line 1b is arranged from one end in the bobbin axial direction to the other end is formed. The layer-wound layer is indicated by a solid line, and in the inner layer of the n-th layer wound layer, the (n-1) is composed of a plurality of arrangement portions arranged from the other side end in the bobbin axis direction to the side end. The layer winding layer is indicated by a broken line.

In (b) and (b) of FIG. 4, the (n+1)th winding layer is formed by a plurality of matching portions in which the dip plating line 1b is arranged from one end in the bobbin axial direction to the other end. The solid line indicates that, in one of the inner layers of the (n+1)th layer wound layer, the other side end from the bobbin axis direction is arranged to the side end. The n-th winding layer composed of the plurality of arrangement portions is indicated by a broken line.

5(a) is an end view of the line A-A in FIG. 4(b), and FIG. 5(b) is an end view of the line B-B in FIG. 4(b). Fig. 7(a) is an end view of the line A-A in Fig. 6(b), and Fig. 7(b) is an end view showing the line B-B in Fig. 6(b).

As shown in Fig. 4 (a), (b) and Figs. 6 (a) and (b), in the wound layer in which the outer side of the wire frame is bonded to the inner side in the radial direction, the immersion plating line constituting the inner wound layer is formed. The lead angle (α) of the arrangement portion of 1b and the lead angle (-α) of the arrangement portion of the immersion plating line 1b constituting the outer wound layer are opposite to each other, that is, the two are respectively the direction of the bobbin axis The upper vertical direction is opposite to the vertical direction.

Therefore, in the wound layer in which the outer side of the wire frame is adjacent to the inner side in the radial direction, the arrangement portion of the immersion plating line 1b constituting the outer wound layer is at least a part of the circumferential direction of the wire frame (two places in the circumferential direction of the wire frame) The spanning portion 130 of the portion of the immersion plating line 1b constituting the inner wound layer is formed, that is, the adjacent portions (intersections) are overlapped.

In this case, the spanning portion 130 will be juxtaposed in a plurality of lines along the bobbin axis direction to form an axial direction span 130L (cross line).

Here, as shown in FIG. 4 to FIG. 7, in the arrangement portion of the dip plating line 1b constituting the (n-1)th layer, the crossing portion 130 spanning the arrangement portion of the immersion plating line 1b constituting the nth layer is formed. After the alignment along the line axis direction, the formed axial direction span 130L is set as the axial direction span 130La, and the (n+1)th layer is formed in the arrangement portion of the immersion plating line 1b constituting the nth layer. The immersion plating line 1b has a spanning portion 130 spanned by the arrangement portion, along the wire frame After the arrangement in the axial direction, the formed axial direction crossing line 130L is set as the axial direction crossing line 130Lb.

Further, for example, when the traverse pitch P is set to 2.0 times the citch pitch p, according to the set traverse pitch P, as in FIGS. 4(a) and (b) and FIGS. 5(a) and (b), In particular, as shown in FIGS. 4(b) and 5(b), as the wound layer is cumulatively laminated in a plurality of layers, the axial direction span 130L (130La, 130Lb) is lined in each of the wound layers. When an offset occurs in the circumferential direction (the two jumpers coincide), the portion of the axial direction spanning line 130L whose stack is accumulated across the portion 130 will form a convex portion 131, and the portion other than the portion 130 will form the concave portion 132. In other words, in the case where the aforementioned axial direction span 130L is offset in the circumferential direction of the bobbin in each of the wound layers (the two jumpers are uniformly overlapped), the convex portions 131 and the concave portions in the uniformly overlapping portions thereof The portion 132 is formed in a concavo-convex winding bulging portion 133 in the axial direction of the bobbin.

In this case, the axial direction span 130L is in a uniform winding state in the circumferential direction of the bobbin in each of the wound layers, that is, the aspect in which the embossed portion 133 is formed in the embossed shape, at the traverse pitch When P is set to a desired preset value, it is accompanied by the fact that as the value of the traverse pitch P becomes larger, the possibility of the winding state of the concavo-convex winding bulging portion 133 is relatively increased.

Further, the axial direction span 130L is in a uniform winding state in the circumferential direction of the bobbin in each of the wound layers, in other words, the aforementioned pattern of generating the concavo-convex winding bulging portion 133 will be as in FIG. As shown in Fig. 5, it can be seen through experiments that this is produced when the traverse pitch P is set to a value close to 2.0 times the cue spacing p.

On the other hand, as shown in FIG. 6 and FIG. 7, for example, when the traverse pitch P is set to 2.5 times the cue spacing p, the (n-1)th layer is formed according to the set traverse pitch P value. The line direction 130La with the nth layer axis direction and the circumferential direction of the wire frame 130Lb constituting the nth layer and the (n+1)th layer axis direction will not coincide with each other, so that the axis direction line line 130L can be in each winding layer. Dispersion in the circumferential direction of the wire frame prevents the convex portion 131 and the concave portion 132 from juxtaposed in the axial direction of the frame to form the uneven-shaped winding bulging portion 133.

Therefore, in order to avoid the phenomenon that the uneven-shaped winding bulging portion 133 generated in each layer is offsetly wound in the circumferential direction, the traverse pitch P is preferably set to a value other than the 2.0-folder pitch p.

In the following, the experiment content of the effectiveness confirmation will be explained.

(Effective confirmation, inspection)

In the present experiment, the immersion plating line reel 10 obtained by continuously traversing the immersion plating line 1b with respect to the wire frame 200 is individually formed at a predetermined traverse pitch P, and these net frames 200 are made. The dip-plated wire package 10 which is wound up and assembled with the low-resistance immersion plating line 1b is a sample, and it is appropriate to verify from the viewpoint of expressing the winding assembly characteristics, that is, the ease of occurrence of the winding collapse phenomenon. The traverse distance P value.

Moreover, the dip plating line 1b wound up in the wire frame 200 was low-resistance by the manufacturing method mentioned above, and the immersion plating line of the immersion-plating thickness of 40 micrometer shown in Table 1 was formed.

【Table 1】

Experimental condition

Use size...square line (0.16 x 2.0(w)mm)

Lead-free plating wire (plating thickness 40 μm )

Coiler specifications: flat angle coiler (line frame traverse coiler)

Coiling tension: fixed value 1.5N (weight: 150g / one)

The axial length of the body of the wire frame is L...90mm

The diameter of the body of the wire frame...100mm

The traverse pitch P is as shown in Table 2, and is set to multiply the traverse pitch P by a preset magnification of 1.0 times the fixed-pitch pitch of p to 2.8 times to obtain a total of 15 kinds of values, and the traverse pitch should be The value of P is made into 15 kinds of immersion wire package reel 10 .

Further, in order to prevent the alignment portions of the dip plating line 1b arranged along the axial direction of the bobbin from overlapping each other, the grid spacing p is set to the width of the dip plating line 1b after considering the gap between the width of the dip line 1b and the length in the bobbin axis direction. (w = 2.0 mm) plus 2.4 mm of 0.4 mm.

This experiment is to evaluate the appearance of individual winding patterns and the drop test for the 15 kinds of immersion wire package wire racks 10 in the above table, and find the most appropriate horizontal direction from the viewpoint of the winding assembly characteristics based on the experimental results. Dynamic spacing P.

The appearance evaluation of the wound state is confirmed by whether or not the periphery of the surface of the immersion plating wire reel 10 has irregularities or bulges.

Further, the unevenness of the periphery of the surface of the dip-plated wire package 10 means that at least a part of the peripheral portion of the wire-wound wire package 10 has a concave portion which is concave in the radial direction of the wire frame 200. Both of the convex convex portions and the convex convex portions are alternately overlapped and formed in the concavo-convex winding bulging portion 133.

The bulging of the periphery of the surface of the dip-plated wire package 10 refers to the peripheral portion of the immersion wire package 10, and at least a part of the bulging portion of the entire wire frame direction.

In addition, the wire rack drop experiment was carried out in the following manner.

As shown in Fig. 8, first, the dip-plated wire package 10 is lifted to a height of 2.0 cm (H) from the ground of the horizontal cement floor, and the wire frame axis is naturally dropped in a horizontal posture to apply thereto. With an impact.

The immersion plating wire bobbin 10 is repeatedly subjected to a drop test by winding, and the immersion plating wire 1b of the main body portion of the winding bobbin 200 is wound on the both sides in the axial direction of the bobbin main body portion 201 due to the impact of the falling. The bobbin collar portion 202 is displaced such that a gap is created between the bobbin collar portion 202 and the dip line 1b. After the gap is measured using the gap detector, the number of drops required to reach the predetermined gap size (0.5 mm, 1.0 mm, 2.0 mm) is calculated and compared with the respective traverse pitch P.

In other words, if the gap between the bobbin collar portion 202 and the dip plating line 1b reaches a predetermined gap size, the more the bobbin 200 is dropped, the more difficult the winding collapse occurs. This wire rack drop experiment, The case where the gap between the bobbin collar portion 202 and the dip plating line 1b reaches 2.0 mm and the number of drops is less than 10 times is defined as "failed", and when it exceeds 10 times or more, it is defined as "acceptable".

In addition, in the wire drop test, in order to reduce the error caused by the winding collapse at the time of falling, in each drop experiment, the preset horizontal posture and the horizontal posture are reversed at the same time. Experiments were carried out in two ways in which the two sides of the bobbin axis were opposite to each other in a horizontal posture. For the gap measurement between the bobbin collar portion 202 and the dip plating line 1b, the side end and the other side end in the axial direction are separately measured while measuring, and a larger value is recorded.

The results of the above-described evaluation of the appearance of the wound state and the result of the wire drop test are shown in Table 2 and FIG.

In addition, FIG. 9 is a graph showing the number of drops of the gap between the bobbin collar portion 202 and the dip plating line 1b reaching 2.0 mm in the wire rack drop experiment under the setting results of the above-described 15 kinds of traverse pitch P. the result of.

As shown in Table 2, in the wire rack drop test for verifying the winding collapse characteristics, the sample with the traverse pitch P set for the result of the "failed" sample was examined for the appearance evaluation. It can be found that at least one of the concavo-convex portion and the bulged portion is present on the peripheral surface of the dip-plated wire package.

As a result of the above, it is understood that the uneven portion or the bulged portion existing on the outer peripheral surface of the immersion-plated wire package 10 has a causal relationship with the number of drops indicating the winding assembly characteristics. Therefore, it is understood that in order to prevent the winding from collapsing, Preventing the uneven surface portion and the bulging portion of the peripheral surface of the immersion plating wire package 10 The winding aspect of both is of great significance.

For example, when the traverse pitch P is set to a value of 2.0 times the cue spacing p, as shown in the photographs of FIGS. 13 and 14, the concave and convex portions are generated on the peripheral surface of the immersion wire reeling bobbin 10, As shown in Fig. 4 (b) and Fig. 5 (b), in the direction along the bobbin axis, the winding state of the concavo-convex winding bulging portion 133 having the convex portion 131 and the concave portion 132 is alternately formed. .

Further, the convex portion 131 and the concave portion 132 have a step difference of about 3 mm to 8 mm in size with each other.

Next, as for the convex portion in the concavo-convex portion, as shown in FIG. 5(b), the arrangement portion of the wound assembly dip plating line 1b is stacked in the different layers in the different layers, and the span portion 130 is stacked. The convex portion 131.

Further, the finger portion is actually touched with the convex portion 131, and it is found that the convex portion 131 is wound and collapsed in the direction of the concave portion 132, and the winding misalignment occurs, so that it can be known that the wire frame is wrapped in the dip-plated wire. A part of the outer peripheral surface of the outer surface of the outer surface of the outer surface of the outer surface of the outer surface of the outer surface of the outer surface of the outer surface of the outer surface of the outer surface of the outer surface of the outer surface of the outer surface of the outer surface of the outer surface of the outer surface of the outer surface of the outer surface of the outer surface of the outer surface of the outer surface of the outer surface of the outer surface of the outer surface of the outer surface of the outer surface of the outer surface of the outer surface of the outer surface.

Further, the immersion plating line package 10 having the traverse pitch P of 1.0 times the grid spacing p is before the start of the drop test of the wire frame, and the arrangement portions of the immersion plating line 1b in the direction of the wire frame axis are approximately not provided with a gap. The state of the whole column, so at first glance, it is intuitively considered that the winding collapse phenomenon is difficult to occur in a neat winding state.

However, if the rack drop test is performed, if the traverse pitch P is set to 1.0. When the value of the pitch p is doubled, it is found that a bulging portion is generated on the peripheral surface of the immersion wire package 10, resulting in a "fail" of the drop test result.

Therefore, it has been confirmed from experiments that in the case of using the low-endurance immersion plating line 1b, in order not to apply a load to the immersion plating line 1b, the immersion plating line 1b must be wound on the wire frame 200 under a low winding assembly tension. In the case where the traverse pitch P is set to 1.0 times the grid spacing, the frictional resistance of the immersion plating line 1b wound by the plurality of layers in the respective wound layers after the winding of the plurality of layers is particularly reduced. Therefore, the phenomenon of winding collapse is also more likely to occur.

It is worth mentioning that, as shown in FIG. 9, even if the traverse pitch P is set to 1.0 times the second half or 2.0 times the value of the fixed-pitch pitch p, the result of the wire frame drop test is not necessarily "failed". However, in general, as the traverse pitch P is set to a value larger than the 1.0-fold stop pitch p, the probability that the wire frame drop test result is unqualified will become larger and larger.

For example, if the traverse pitch P is set to a value larger than the 2.5-fold stop pitch p, the result of the drop test will be "failed", so it can be confirmed that it is preferably set to 2.5 times or less. The value.

Further, when the traverse pitch P is set to a value of 2.0 times the second half of the cue spacing p, the dip plating line 1b wound around the wire frame 200 is dent and bent.

From this point, it can also be confirmed that the traverse pitch P should preferably be set to a value equal to or less than 2.5 times the cue spacing p.

In contrast, the traverse pitch P is set to 1.2 times the stop pitch p When the value is used, the result of the drop test is "qualified". In other values, for example, when the traverse pitch P is set to a value of 1.8 times or 2.5 times the fixed pitch p, the experimental result is also "qualified".

As shown in Table 2, the evaluation results of the appearance of the wound state of the immersion-plated wire package 10 are as shown in Table 2, and there are no uneven portions and bulging portions on the peripheral surface, as shown in the photographs of Figs. 10 to 12, The immersion plating line 1b is in a stable winding state along the direction of the wire frame axis.

Further, in the photograph of Fig. 10, a part of the dip plating line 1b wound and assembled to the wire frame 200 protrudes outward in the radial direction of the wire frame, but this is the front end portion of the dip plating line 1b, and is not affected by the winding bulging. produce.

In other words, through the traverse winding, the low-endurance immersion plating line 1b is opposed to the bobbin main body portion 201 at a predetermined one traverse pitch P from one side end of the bobbin axis direction to the other side end. While being wound up in a row, and outside the winding layer after the winding of the entire row, the other side end in the direction of the bobbin axis is repeatedly wound around the side end in an entire row so that the dip plating line 1b is along the bobbin axis The wound assembly layer formed by the entire column portion arranged in the entire direction forms a wound pattern in which a plurality of layers are laminated on each other, and further, in the wound layer in which the outer side of the wire frame in the radial direction is adjacently bonded to the inner side, the outer wound layer is formed. The arrangement portion of the immersion plating line 1b spans the arrangement portion of the immersion plating line 1b constituting the inner wound layer, and is aligned in the axial direction of the bobbin while forming a winding pattern in the axial direction across the respective wound layers.

According to the present embodiment, the immersion plating line 1b is wound up by setting the traverse pitch P to a value in which the axial direction span 130L is dispersed in the circumferential direction of the wire frame in each of the wound layers, for example, a set pitch pitch p. 1.2 times, 1.8 times or 2.5 times, the axial direction span 130L can be dispersed inconsistently in the circumferential direction of the bobbin in each of the wound layers, and the effect of preventing the occurrence of the concavo-convex winding bulging portion 133 can be achieved.

Even if the outer peripheral surface of the dip-plated wire reel 10 is actually touched with a finger or the like, there is no occurrence of winding misalignment, winding collapse, or winding loosening.

Therefore, in the conditions set in this experiment, the traverse pitch is preferably set to a value of 1.2 times, 1.8 times or 2.5 times the set pitch p, and these values are also applicable to the need to keep the 0.2% endurance value low. The numerical value of the solar cell wire is the optimum value of its traverse pitch P. In particular, when the traverse pitch is 1.2 times the grid spacing, the size of the spiral track angle due to the spiral winding assembly can be effectively suppressed, and the immersion plating line 1b is prevented from being affected by the dent, so that it is optimal. Set value.

In addition, in the effect confirmation experiment, in addition to the conditions and manufacturing conditions of Table 1, the immersion plating line 1b was subjected to the traverse winding supplement and additional experiments (hereinafter, Said additional experiment).

In this additional experiment, the immersion plating line 1b is wound and assembled to the wire frame 200 having the length of the wire frame axial direction of different lengths, or the set spacing p is set to be different from the numerical condition set in the above Table 1. Or manufacturing conditions.

As a result of the additional experiment, when the traverse pitch P is set to 1.0 times the cavitation pitch p or 2.0 times, as shown in FIG. 9, the conclusion is consistent with the above-mentioned effect confirmation experiment result, which is also unqualified and confirmed to be prone to roll. Collapse Collapsed winding pattern. From this, it is understood that the traverse pitch P is set to an experimental condition of 1.0 times the cavitation pitch p or 2.0 times, and the winding state in which the winding collapse is likely to occur can be reproduced. In addition, the experimental results set to other values also have the same conclusions as the results of the above-described effectiveness confirmation experiments.

On the other hand, when the traverse pitch P was set to a value of 1.2 times the cue spacing p, the result of the wire rack drop test was "acceptable", and it was confirmed that the phenomenon of winding collapse was hard to occur, and the reproducibility of the experiment was obtained. Therefore, it can be determined again that the traverse pitch P should preferably be set to a value of 1.2 times the set pitch p.

Further, the traverse pitch P is in the range of 1.0 times the frame spacing to 2.5 times or less, and the traverse pitch P is 1.8 times or more in the frame spacing except that the value is 1.2 times the pitch interval. In the case of 2.5 times, it also has a better winding state. Therefore, it can be confirmed that the distribution result of the traverse pitch P value of the wire rack drop test result is "acceptable", and has the same distribution tendency as the above drop experiment. .

However, these experimental data may be subject to manufacturing conditions such as the axial length of the bobbin or the error generated during the manufacturing process, which may result in a situation in which the traverse pitch P value obtained above is completely identical, that is, it is not necessarily It has experimental reproducibility.

However, the optimum traverse pitch P value can be accurately found based on the manufacturing conditions through the following steps.

First, if the traverse pitch P is set to a value other than the optimum value of 1.2 times the cue spacing p, the traverse pitch P must first be within the range of 1.0 times the crib spacing p to 2.5 times the cue spacing p, deducting the experience. After the value of the winding gap is close to the value of 2.0 times the spacing of the grid, the remaining The preset value is set to a tentative value.

Next, the traverse pitch P is wound and assembled under the provisional value set as described above, and it is assumed that traverse is generated when unevenness occurs on the peripheral surface or a swelled portion is formed in the middle of winding assembly. After the pitch P is reset to a value near the above-mentioned 1.8 times or 2.5 times the fixed pitch p and the like, the winding assembly is performed again, thereby smoothly finding the optimum traverse pitch under the current manufacturing conditions. P value.

In addition, the traverse pitch P is not limited to a fixed value when the immersion plating line 1b is traversed with respect to the wire frame 200, and the traverse pitch P may be traversed to the wire frame 200 at the immersion plating line 1b. At the same time of winding, it is possible to prevent an immediate change under the premise that uneven portions or bulging portions are formed on the peripheral surface of the immersion wire reeling bobbin 10.

As described above, while the immersion plating line 1b is wound and assembled to the wire frame 200, the means for confirming whether the peripheral surface of the immersion plating wire package 10 is uneven or bulged may be By visual inspection, the traverse pitch P is changed by manually inputting the value of the traverse pitch P arbitrarily.

Or, while traversing the winding, the sensor is used to instantly detect whether the concave or convex portion or the bulging portion is generated, and according to the detection signal of the sensor, if the concave or convex portion or the bulging portion is generated, the automatic control is automatically performed. The traverse pitch P value is changed to eliminate the aforementioned concavo-convex portion or bulging portion.

Also, the sensor can be, for example, an infrared sensor or a charge coupled (CCD) camera.
