Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of copper wire, in particular to a production device of round-flat alternating interconnection copper strip. BACKGROUND

[0002] Photovoltaic cell panel is mainly composed of cell piece and interconnection strip welded together to convert light energy into electrical energy by sunlight. The cell piece is made of silicon, and the interconnection strip is composed of copper-based strip coated with tin alloy. The interconnection strip is welded on the main grid line of the cell piece. The existing interconnection strip is mostly copper wire with consistent diameter or copper strip with consistent thickness and width. The interconnection strip is generally welded on the front and back of the cell piece in sequence. The welding strength is reduced due to the small contact area between the copper wire and the cell piece. If the copper strip with consistent width and thickness is used, there is a large resistance and power loss, and the reflection efficiency of the cell piece is low, which affects the photovoltaic power generation efficiency. SUMMARY

[0003] The purpose of the present application is to provide a round-flat alternating interconnection copper strip, which can increase the welding strength of the interconnection copper strip and the cell piece and improve the connection stability of the interconnection strip and the cell piece by round-flat alternating arrangement.

[0004] The production device of the round-flat alternating interconnection copper strip can facilitate the production and processing of the round-flat alternating interconnection copper strip.

[0005] The above technical purpose of the present application is achieved by the following technical scheme:

[0006] A round-flat alternating interconnection copper strip includes a copper wire, a plurality of linearly distributed copper flat strip segments are formed on the copper wire, and a gradual change segment is formed at both ends of the copper flat strip segment. In use, the round part of the copper wire is welded on the front of the cell piece, and the copper flat strip segment is welded on the back of the cell piece. Since the back of the cell piece does not need to be illuminated, the flat arrangement does not affect the photovoltaic power generation efficiency and can increase the contact area of the interconnection copper strip and the back of the cell piece, thereby increasing the welding strength and improving the connection stability of the interconnection strip and the cell piece.

[0007] A production device of a round-flat alternating interconnection copper strip includes a first roller and a second roller arranged vertically, the first roller includes a first shaft fixedly connected with a deforming roller body, the second roller includes a second shaft coaxially fixedly connected with a circular roller body, and a copper wire passes between the deforming roller body and the circular roller body.

[0008] The outer wall of the deforming roller body includes a first circular arc segment with a radius R1, a second circular arc segment with a radius R2, a straight line segment tangent to the end of the first circular arc segment, a round corner segment connecting the straight line segment and the end of the second circular arc segment, R2>R1, and the first circular arc segment and the second circular arc segment are coaxially arranged with the first shaft.

[0009] The circular roller body is a cylinder with a radius of R1;

[0010] The first and second wheel shafts are rotationally connected to a rolling body, and the rolling body is arranged on a rack.

[0011] Through the above technical solution, the copper wire of a certain diameter after pre-drawing passes through the gap between the deformation roller body and the circular roller body from left to right, and the right end of the copper wire is provided with a traction.

[0012] The first and second rollers rotate in opposite directions and at the same angular velocity. When the circular corner section and the straight line section rotate to the upper side of the circular roller body, the gap between the deformation roller body and the circular roller body gradually decreases, thereby rolling the copper wire to form a gradual change section. When the second circular arc section rotates to the upper side of the circular roller body, the gap between the deformation roller body and the circular roller body can be kept unchanged. During this period, the rolled copper strip can maintain the same thickness. This section is a copper flat strip section. When the second circular arc section moves away from the upper side of the circular roller body, the other circular corner section and the other straight line section pass through the upper side of the circular roller body again. The gap between the deformation roller body and the circular roller body gradually increases again, thereby forming a gradual change section again, so that the rolled copper strip becomes thicker. When the first circular arc section rotates to the upper side of the circular roller body, the copper wire is not pressed and remains unchanged.

[0013] The application further provides that the center distance L1 between the first wheel shaft and the second wheel shaft is equal to the diameter D of the copper wire plus twice R1.

[0014] Through the above technical solution, by controlling the center distance L1 between the first wheel shaft and the second wheel shaft, the size of the rolled copper wire can be ensured. The diameter of one end of the copper wire circle is still D, and the thickness of the flat strip section of the rolled copper wire is L1-R1-R2.

[0019] When the center distance L1 between the first axle and the second axle is less than the sum of the diameter D of the copper wire and twice R1 after the adjustment through the hand wheel, the copper wire after being rolled by the first rolling wheel and the second rolling wheel is in a state of a thick flat copper strip, a gradually thin copper strip, a thin flat copper strip, a gradually thick copper strip, and a thick flat copper strip, which is cyclically repeated.

[0020] The base is further provided with a stepped bearing hole formed thereon and arranged from small at the top to large at the bottom; and the middle part of the adjusting sleeve is formed with a support ring.

[0021] The upper end of the adjusting sleeve is inserted into two first bearings arranged above and below and matched with each other, the first bearings are inserted into and fixed in the stepped bearing hole, the support sleeve is clamped between the outer ring end faces of the two first bearings, and the upper end face of the outer ring of the upper first bearing is pressed against the stepped face of the stepped bearing hole; the outer ring of the lower first bearing drives the lower end face to be pressed against the upper end protruding ring of the thrust bearing, and the lower end of the thrust bearing is pressed against the support ring.

[0022] When the first rolling wheel and the second rolling wheel roll the copper wire, the first rolling wheel is subjected to the upward reaction force of the copper wire, the first rolling wheel is pre-moved upward, the support ring is pressed against the thrust bearing, and the thrust bearing is pressed against the first bearing, so that the support ring is limited to move upward, thereby limiting the upward movement of the adjusting sleeve and preventing the upward movement of the first rolling wheel, and the distance between the first rolling wheel and the second rolling wheel is kept relatively stable; the thrust bearing is pressed against the outer ring of the first bearing, so that the rotation of the adjusting sleeve is not affected and the damage to the first bearing is reduced; if the support ring is directly pressed against the inner ring of the first bearing, the inner ring of the first bearing is damaged.

[0025] The gear transmission can ensure that the angular velocities of the first roller and the second roller are the same.

[0026] The bottom of the rolling main body slides on the second guide rails arranged in the front-rear direction, and the second guide rails are fixed on the rack.

[0027] The rear end of the rolling main body is fixedly connected with the end of the telescopic rod of the electric telescopic cylinder, and the electric telescopic cylinder is fixed on the rack.

[0028] The left end of the rolling main body is fixed with an induction block, and the opposite side of the induction block is provided with two proximity sensors arranged in the front-rear direction, each proximity sensor is fixed on a corresponding rectangular slide block, the rectangular slide block is inserted into a rectangular slide sleeve, and the rectangular slide sleeve is fixed on the rack; each rectangular slide block is rotationally connected with an adjusting screw arranged in the front-rear direction, and the adjusting screw is screwed on the side wall of the rectangular slide sleeve. The proximity sensors are electrically connected with a controller, and the controller controls the telescopic direction of the electric telescopic cylinder.

[0029] Through the technical scheme, the extension and contraction of the telescopic rod of the electric telescopic cylinder can drive the rolling main body to move forward and backward, the rolling main body can drive the first roller and the second roller to move forward and backward, the first roller and the second roller move forward and backward relative to the copper wire, so that the first roller and the second roller do not roll the copper wire at the same position, the service life of the first roller and the second roller can be improved, and the stability of the rolled copper strip can be ensured. Because the rollers do not move, the copper wire is always rolled at the same place, the place where the copper wire is rolled is more severely worn, the service life of the rollers is reduced, and the size stability of the copper strip is also affected.

[0030] The deformed roller body and the circular roller body further comprise a carbon steel layer and a tungsten steel layer, and the tungsten steel layer is arranged outside the carbon steel layer.

[0031] Through the technical scheme, the tungsten steel layer has high hardness, the service life of the roller can be improved, and the size stability of the rolled copper strip can be ensured.

[0032] The deformed roller body and the circular roller body are each formed with a cooling cavity, a first water outlet through hole and a first water inlet through hole are formed on the inner side wall of the cooling cavity and arranged in the front-rear direction; the cooling cavity, the first water outlet through hole and the first water inlet through hole are arranged in the carbon steel layer of the corresponding deformed roller body or circular roller body.

[0035] The front end of the first axle and the second axle is respectively rotatably connected with a water receiving head through a bearing;

[0036] The water receiving head comprises a water receiving head body, the water receiving head body is formed with a large-diameter insertion hole and a small-diameter insertion hole arranged coaxially, the front end of the first axle and the second axle is inserted into the large-diameter insertion hole of the corresponding water receiving head body, and the water passing pipe of the front end of the first axle and the second axle is inserted into the small-diameter insertion hole of the corresponding water receiving head body;

[0038] The fourth water outlet through hole is connected with a water outlet branch pipe, and the fourth water inlet through hole is connected with a water inlet branch pipe.

[0039] Through the above technical solution, since the thermal expansion and contraction amounts of the tungsten steel layer and the carbon steel layer are different, the deformation amount of the carbon steel layer is greater than that of the tungsten steel layer;

[0040] The cooling water in the outside world enters the small-diameter insertion hole through the water inlet branch pipe, then enters the second water inlet long hole through the water passing pipe, enters the cooling cavity through the third water inlet through hole and the first water inlet through hole, the water in the cooling cavity cools the carbon steel layer, the water completing the cooling work enters the second water outlet long hole through the first water outlet through hole and the third water outlet through hole, then flows into the large-diameter insertion hole, and finally flows out to the water outlet branch pipe from the fourth water outlet through hole.

[0041] The application further provides that two water outlet branch pipes are connected with two ends of a water outlet tee joint, and a water outlet main pipe is connected to a third end of the water outlet tee joint.

[0044] The outstanding effect of the application is:

[0045] By setting the round and flat alternately, one section of the round is set on the front of the battery piece, and one section of the flat is set on the back of the battery piece, which can increase the welding strength between the interconnecting strip and the battery piece and improve the connection stability between the two without affecting the reflection of the interconnecting strip light;

[0073] The specific embodiments of the present application are described in further detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application, but are not used to limit the scope of the present application.

[0074] The following references Figures 1 to 14 The present application is described as follows:

[0075] A round-flat alternating interconnection copper strip includes a copper wire 90, a plurality of linearly distributed copper flat strip segments 901 are formed on the copper wire 90, and gradual change segments 902 are formed at both ends of the copper flat strip segments 901. In use, a round section of the copper wire is welded on the front of a battery piece, and the copper flat strip segments are welded on the back of the battery piece. Since the back of the battery piece does not need to be illuminated, the flat arrangement does not affect the photovoltaic power generation efficiency and can increase the contact area of the interconnection copper strip with the back of the battery piece, increase the welding strength, and thus improve the connection stability of the interconnection strip and the battery piece.

[0076] A production device of a round-flat alternating interconnection copper strip includes a first rolling wheel 10 and a second rolling wheel 20 arranged above and below, the first rolling wheel 10 includes a first shaft 101 and a deformation rolling wheel body 102 fixedly connected, the second rolling wheel 20 includes a second shaft 201 and a circular rolling wheel body 202 coaxially fixedly connected, and a copper wire 90 passes between the deformation rolling wheel body 102 and the circular rolling wheel body 202.

[0077] The outer wall of the deformation rolling wheel body 102 includes a first circular arc segment 1021 with a radius R1, a second circular arc segment 1022 with a radius R2, a straight line segment 1023 tangent to the end of the first circular arc segment 1021, a round corner segment 1024 connecting the straight line segment 1023 and the end of the second circular arc segment 1022, the R2>R1, and the first circular arc segment 1021 and the second circular arc segment 1022 are coaxially arranged with the first shaft 101.

[0078] The circular rolling wheel body 202 is a column with a radius R1;

[0079] The first shaft 101 and the second shaft 201 are rotationally connected to a rolling main body 30, and the rolling main body 30 is arranged on a rack 31.

[0080] A copper wire with a certain diameter after pre-drawing passes between the gap between the deformation rolling wheel body 102 and the circular rolling wheel body 202 from left to right, and the right end of the copper wire is provided with a traction;

[0081] The first roller and the second roller rotate in opposite directions and at the same angular velocity. When the first circular arc segment 1024 and the straight line segment move above the circular roller body 202, the gap between the deforming roller body 102 and the circular roller body 202 gradually decreases, so that the copper wire is rolled. This segment is a gradual change segment. When the second circular arc segment moves above the circular roller body 202, the gap between the deforming roller body 102 and the circular roller body 202 remains unchanged. In this process, the rolled copper strip maintains the same thickness. This segment is a copper flat strip segment. When the second circular arc segment moves away from the top of the circular roller body 202, another circular arc segment and another straight line segment move above the circular roller body 202 again. The gap between the deforming roller body 102 and the circular roller body 202 gradually increases, so that the rolled copper strip becomes thicker. When the first circular arc segment moves above the circular roller body 202, the copper wire is not pressed and remains unchanged.

[0082] The center distance L1 between the first axle 101 and the second axle 201 is equal to the diameter D of the copper wire 90 plus twice R1.

[0083] By controlling the center distance L1 between the first axle 101 and the second axle 201, the size of the rolled copper wire can be ensured. The diameter of one end of the copper wire 90 is still D, and the thickness of the flat segment of the rolled copper wire is L1-R1-R2.

[0084] The rolling body 30 comprises a pair of adjusting blocks 301 and a pair of fixed blocks 302 arranged in an up-down manner. The fixed blocks 302 are fixed on the base 303, and the adjusting blocks 301 are slidingly connected to the first guide rails arranged vertically. The first guide rails are fixedly connected to the base 303.

[0085] The two ends of the first axle 101 are rotatably connected to the two adjusting blocks 301 through bearings, and the two ends of the second axle 201 are rotatably connected to the two fixed blocks 302 through bearings.

[0086] Each adjusting block 301 is fixed on the lower end of an adjusting screw 304. The upper end of the adjusting screw 304 is screwed into an adjusting nut 305, which is rotatably connected to the upper end of the base 303. The adjusting nut 305 extends through the upper end of the base 303 and is fixed with a worm wheel 306. The two worm wheels 306 are meshed with the same worm 307, the two ends of which are rotatably connected to a support 308, which is fixedly connected to the base 303. One end of the worm 307 is connected with a hand wheel 309.

[0087] Rotating the hand wheel, the hand wheel drives the worm to rotate, the worm drives the two worm gears to rotate synchronously, the worm gears drive the adjusting sleeve to rotate, the adjusting sleeve drives the adjusting screw to move up or down, the adjusting screw drives the adjusting block to move, the adjusting block drives the first axle to move up or down, thereby adjusting the height of the first roller, thereby adjusting the gap between the first roller and the second roller; through the hand wheel adjustment, the distance between the two rollers is conveniently controlled, thereby controlling the size of the copper strip after rolling.

[0088] When the center distance L1 between the first axle 101 and the second axle 201 is less than the sum of the diameter D of the copper wire 90 and twice R1 after adjustment by the hand wheel, the state after the copper wire is rolled by the first roller and the second roller is a thick flat copper strip, a gradually thinned copper strip, a thin flat copper strip, a gradually thickened copper strip, a thick flat copper strip, and so on.

[0089] The base 303 is formed with a stepped bearing hole 3031 arranged from small at the top to large at the bottom; the middle part of the adjusting sleeve 305 is formed with a support ring 3051;

[0090] The upper end of the adjusting sleeve 305 is inserted into the two first bearings 310 arranged above and below and matched with each other, the first bearings 310 are inserted into and fixed in the stepped bearing hole 3031, the outer ring end faces of the two first bearings 310 are clamped with the support sleeve 311, the upper end face of the outer ring of the upper first bearing 310 is pressed against the stepped face of the stepped bearing hole 3031; the outer ring of the lower first bearing 310 drives the lower end face to be pressed against the upper end protruding ring 3121 of the thrust bearing 312, and the lower end of the thrust bearing 312 is pressed against the support ring 3051.

[0091] When the first roller and the second roller roll the copper wire, the first roller is subjected to the upward reaction force of the copper wire, the first roller is pre-moved upward, the support ring is pressed against the thrust bearing, the thrust bearing is pressed against the first bearing, the support ring is limited to move upward, thereby limiting the upward movement of the adjusting sleeve, thereby preventing the upward movement of the first roller, so that the distance between the first roller and the second roller remains relatively stable; the thrust bearing is pressed against the outer ring of the first bearing, which can ensure that the rotation of the adjusting sleeve is not affected and can reduce the damage to the first bearing. If the support ring is directly pressed against the inner ring of the first bearing, the inner ring of the first bearing is damaged.

[0092] The rear end of the first axle 101 and the rear end of the second axle 201 are each connected with a synchronous gear 802 through a universal joint 801, the two synchronous gears 802 are meshed with each other and rotationally connected in a gear box 803, the gear box 803 is fixed on the rack 31; one of the synchronous gears 802 is meshed with a drive gear 804, the drive gear 804 is fixed on the motor shaft of a first motor 805, and the first motor 805 is fixed on the gear box 803.

[0093] The first motor drives the driving gear to rotate, the driving gear drives the synchronous gear to rotate, one synchronous gear drives the first axle to rotate through the universal chain shaft, the other synchronous gear drives the second axle to rotate through the other universal chain shaft, the first axle drives the deformed roller body to rotate, and the second axle drives the circular roller body to rotate, so as to perform the rolling work on the copper wire.

[0094] The gear transmission can ensure that the angular velocities of the first roller and the second roller are the same.

[0095] The bottom of the rolling body 30 slides on the second guide rails 32 arranged in the front-back direction, and the second guide rails 32 are fixed on the rack 31.

[0096] The rear end of the rolling body 31 is fixedly connected with the end of the telescopic rod of the electric telescopic cylinder 33, and the electric telescopic cylinder 33 is fixed on the rack 31.

The proximity sensor is electrically connected with the controller, and the controller controls the extension direction of the electric telescopic cylinder.

[0098] The extension and contraction of the telescopic rod of the electric telescopic cylinder can drive the rolling body to move forward and backward, and the rolling body can drive the first roller and the second roller to move forward and backward, so that the first roller and the second roller move forward and backward relative to the copper wire, so that the first roller and the second roller do not roll the copper wire at the same position, which can improve the service life of the first roller and the second roller, and can ensure the stability of the rolled copper strip, because the rollers do not move and always roll the copper wire at the same position, the rolling position of the copper wire is more seriously worn, which reduces the service life of the rollers and affects the size stability of the copper strip.

[0099] The structure of the deformed roller body 102 and the circular roller body 202 comprises a carbon steel layer 4001 and a tungsten steel layer 4002, and the tungsten steel layer 4002 is arranged outside the carbon steel layer 4001.
