[0001] The present invention relates to the field of round and flat wire processing, and in particular, to a composite double-wire tinning machine. Background Art

[0002] In the manufacturing of photovoltaic equipment, solder tapes must be used to connect between various circuit boards; in the production process of photovoltaic solder tapes, copper wires are first led out by a pay-off device, and then drawn, rolled, annealed, and tinned in sequence. Finally, the processed photovoltaic solder tapes are wound into rolls by a take-up device for easy transportation and storage; in the existing photovoltaic solder tape double-line production equipment, two rolling mechanisms are arranged at intervals, increasing the floor area and volume of the rolling module of the equipment.

[0003] There is a way to share the same main shaft by two sets of rolling rolls, thereby reducing the floor area and volume of the rolling module. However, when applying this method to a double-wire tinning machine, since the rolling discharge directions of the double copper wires are opposite, the copper wires need to be re-arranged. During the arrangement process, the copper wires will cross, and it is easy to occur copper wire winding phenomenon, affecting the normal use of the equipment.

[0004] Therefore, it is an urgent problem to be solved by the present invention to provide a composite double-wire tinning machine in which two sets of rolling rolls share the same main shaft and can avoid copper wire cross-winding at the same time. Summary of the Invention

[0005] Aiming at the above technical problems, the object of the present invention is to overcome the situation in the prior art that there is a way to share the same main shaft by two sets of rolling rolls, thereby reducing the floor area and volume of the rolling module. However, when applying this method to a double-wire tinning machine, since the rolling discharge directions of the double copper wires are opposite, the copper wires need to be re-arranged. During the arrangement process, the copper wires will cross, and it is easy to occur copper wire winding phenomenon, affecting the normal use of the equipment. Thus, a composite double-wire tinning machine in which two sets of rolling rolls share the same main shaft and can avoid copper wire cross-winding at the same time is provided.

[0006] To achieve the above object, the present invention provides a composite double - wire tin - coating integrated machine, and the composite double - wire tin - coating integrated machine includes a rolling module; wherein, the rolling module includes: a mounting frame, a first rolling roller, a second rolling roller, a third rolling roller, a synchronous moving mechanism, a synchronous rotating mechanism, a guide roller assembly, and a guide pipe assembly. The second rolling roller is horizontally rotatably arranged on the mounting frame, and the first rolling roller and the third rolling roller are respectively arranged on both relative sides of the second rolling roller in a relatively reciprocating movable manner through the synchronous moving mechanism. The synchronous rotating mechanism is arranged on one side of the mounting frame and can drive the first rolling roller, the second rolling roller, and the third rolling roller to rotate synchronously. A guide roller assembly is arranged on one side of the first rolling roller and the second rolling roller for guiding round wires forwardly between the first rolling roller and the second rolling roller. A guide pipe assembly is arranged around the circumferences of the second rolling roller and the third rolling roller for guiding round wires reversely between the second rolling roller and the third rolling roller.

[0007] Preferably, the composite double - wire tin - coating machine includes a unwinding module, a rolling module, an annealing module, a tin - coating module, and a winding module arranged in sequence.

[0008] Preferably, a unwinding module is arranged on one side of the rolling module. The guide pipe assembly includes: a first guide pipe and a second guide pipe. One end of the first wire - guiding pipe is used to receive the round wires released by the unwinding module, and the other end is used to guide the round wires reversely between the second rolling roller and the third rolling roller. One end of the second guide pipe is used to receive the round wires, and the other end is used to guide the round wires into the annealing module. The first guide pipe and the second guide pipe adopt an "L - shaped" pipe or a "U - shaped" pipe.

[0009] Preferably, a direction - changing and avoiding pipe is arranged in the second guide pipe for avoiding the first guide pipe.

[0010] Preferably, plug - wire grooves are respectively formed on the first guide pipe and the second guide pipe along their extending directions.

[0011] Preferably, the guide roller assembly includes a plurality of guide rollers arranged in an alternating manner, and a limiting groove is coaxially arranged on the guide rollers.

[0012] Preferably, the synchronous moving mechanism includes: a moving frame and a synchronous driving component. Moving frames are respectively arranged on both relative sides of the second rolling roller in a reciprocating movable manner. The first rolling roller and the third rolling roller are respectively horizontally rotatably arranged on the moving frames. The synchronous driving component is arranged on the mounting frame for driving each moving frame to move relatively and reciprocally synchronously.

[0013] Preferably, the synchronous rotation mechanism includes: a synchronous rotation assembly and a coupling assembly.

[0015] Preferably, a guiding and wire dividing wheel is provided on one set of unwinding mechanism close to the calendering module.

[0016] According to the above technical solution, the beneficial effects of the present invention compared with the prior art are as follows: Since the conveying directions of the round wires by the first calender roll and the second calender roll are different from those by the second calender roll and the third calender roll, it is necessary to positively introduce one set of round wires between the first calender roll and the second calender roll through the guiding roll assembly, and introduce the other set of round wires between the second calender roll and the third calender roll in the reverse direction through the guiding pipe assembly. Since the layout of the round wires is realized through the pipes, the round wires can be prevented from crossing and winding, thereby realizing the movement of synchronously calendering two calender rolls driven by one main shaft, reducing the volume and floor area of the calendering module; and since the first calender roll and the third calender roll are synchronously moved through the synchronous movement mechanism; the first calender roll, the second calender roll, and the third calender roll are synchronously rotated through the synchronous rotation mechanism, which also reduces the volume and floor area of the calendering module.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] To further understand the features, technical means, and the specific purposes and functions achieved by the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0031] Refer to Figure 1 and Figure 2: A composite double-wire tinning machine, the composite double-wire tinning machine includes a rolling module 2; wherein, the rolling module 2 includes: a mounting frame 201, a first rolling roller 202, a second rolling roller 203, a third rolling roller 204, a synchronous moving mechanism 205, a synchronous rotating mechanism 206, a guiding roller assembly 207 and a guiding pipe assembly 208. The second rolling roller 203 is horizontally rotatably arranged on the mounting frame 201. On both relative sides of the second rolling roller 203, a first rolling roller 202 and a third rolling roller 204 are respectively arranged to be relatively reciprocally movable through the synchronous moving mechanism 205. The synchronous rotating mechanism 206 is arranged on one side of the mounting frame 201 and can drive the first rolling roller 202, the second rolling roller 203 and the third rolling roller 204 to rotate synchronously. A guiding roller assembly 207 is arranged on one side of the first rolling roller 202 and the second rolling roller 203 for guiding round wires forwardly between the first rolling roller 202 and the second rolling roller 203. A guiding pipe assembly 208 is arranged around the circumferences of the second rolling roller 203 and the third rolling roller 204 for guiding round wires reversely between the second rolling roller 203 and the third rolling roller 204.

[0032] In this application, since the direction of transporting round wires by the first rolling roller 202 and the second rolling roller 203 is different from the direction of transporting round wires by the second rolling roller 203 and the third rolling roller 204, it is necessary to guide one group of round wires forwardly between the first rolling roller 202 and the second rolling roller 203 through the guiding roller assembly 207, and guide the other group of round wires reversely between the second rolling roller 203 and the third rolling roller 204 through the guiding pipe assembly 208. Since the layout of the round wires is realized through pipes, it can avoid the cross-winding of the round wires, thereby realizing the movement of two rolling rollers being synchronously rolled by one main shaft, reducing the volume and floor area of the rolling module 2; and since the first rolling roller 202 and the third rolling roller 204 are synchronously moved through the synchronous moving mechanism 205; the first rolling roller 202, the second rolling roller 203 and the third rolling roller 204 are synchronously rotated through the synchronous rotating mechanism 206, which also reduces the volume and floor area of the rolling module 2.

[0033] Refer to Figure 7 : The composite double-wire tinning machine includes a unwinding module 1, a rolling module 2, an annealing module, a tinning module and a winding module arranged in sequence.

[0034] The unwinding module 1 and winding module of this application are mainly used for placing and releasing copper wire coils and automatically winding the tinned flat wires. The unwinding device and winding device applicable to this equipment recorded in the existing technology are mainly used; the annealing module includes a heating box and a cooling box. The inside of the heating box is provided with conveying rollers, which are connected to the rolling module 2 through through grooves to heat-treat the rolled copper sheets. The top is equipped with rollers with adjustable heights to adapt to different wire diameters. The cooling box is forced to ventilate and dissipate heat through a fan, and is provided with heat dissipation grooves to accelerate cooling to ensure that the copper sheets reach an appropriate temperature before tinning; the tinning module mainly pre-heats the molten tin pot to the target temperature, adds a tin alloy with a purity ≥ 99.95%, and the ultrasonic oscillator continuously cleans the oxide layer on the surface of the tin liquid. The flat wires pass through the tinning tank at a constant speed, and the upper and lower coating rollers are attached to the surface of the flat wires according to the preset pressure. After passing through the antioxidant coating and nitrogen drying, winding is achieved.

[0035] Refer to Figure 3 : A unwinding module 1 is arranged on one side of the rolling module 2. The guiding pipe assembly 208 includes: a first guiding pipe 20801 and a second guiding pipe 20802. One end of the first guiding wire pipe is used to receive the round wire released by the unwinding module 1, and the other end is used to reversely introduce the round wire between the second rolling roller 203 and the third rolling roller 204. One end of the second guiding pipe 20802 is used to receive the round wire, and the other end is used to introduce the round wire into the annealing module. The first guiding pipe 20801 and the second guiding pipe 20802 adopt an "L-shaped" pipe or a "U-shaped" pipe.

[0036] The first guiding pipe 20801 and the second guiding pipe 20802 of this application adopt a compact "L-shaped" or "U-shaped" layout to avoid the risk of material deviation caused by traditional long-distance guiding; the inner wall of the guiding pipe is polished to reduce the frictional resistance.

[0037] Refer to Figure 4 : A deflection and avoidance pipe 2080201 is arranged in the second guiding pipe 20802 for avoiding the first guiding pipe 20801.

[0038] The deflection and avoidance pipe 2080201 of this application adopts an arc-shaped or zigzag structure, so that the second guiding pipe 20802 naturally deflects its path when passing through the area of the first guiding pipe 20801, making the first guiding pipe 20801 and the second guiding pipe 20802 form a spiral shape as a whole, which can make the two groups of round wires not in the same plane, further reducing the possibility of cross-winding.

[0039] Refer to Figure 3 and Figure 4 : Plug wire grooves are respectively arranged on the first guiding pipe 20801 and the second guiding pipe 20802 along their extending directions.

[0040] In this application, a plug slot is provided to facilitate the user to insert or remove the silk thread into or from the first guiding pipe 20801 and the second guiding pipe 20802.

[0041] Referring to Figure 4 : The guiding roller assembly 207 includes a plurality of guiding rollers arranged alternately, and limiting slots are coaxially arranged on the guiding rollers.

[0042] After the round silk in this application is output from the unwinding module 1, it enters the alternately arranged guiding rollers, gradually calibrates the direction, forms a stable straight path, and the limiting slots contact the round silk during the rolling process to provide a two-way lateral binding force.

[0043] Referring to Figure 3 and Figure 4 : The synchronous moving mechanism 205 includes: a moving frame 20501 and a synchronous driving component 20502. The moving frames 20501 are respectively arranged on the opposite sides of the second calendering roller 203 in a reciprocatingly movable manner. The first calendering roller 202 and the third calendering roller 204 are respectively horizontally rotatably arranged on the moving frame 20501, and the synchronous driving component 20502 is arranged on the mounting frame 201 to drive each moving frame 20501 to move synchronously and reciprocally relative to each other.

[0044] In this application, the synchronous driving component 20502 can adopt the method of driving the bidirectional lead screw 2050202 to rotate by the first rotating motor 2050201. By respectively arranging limiting sliders on the opposite sides of the moving frame 20501 and arranging limiting sliding grooves on the mounting frame 201 that are adapted to the limiting sliders, each moving frame 20501 is driven to move stably and synchronously and reciprocally relative to each other, so as to adjust the distance between the first calendering roller 202 and the third calendering roller 204 and the second calendering roller 203, and further realize the calendering of the round silk.

[0045] Referring to Figure 5 and Figure 6 : The synchronous rotating mechanism 206 includes: a synchronous rotating component 20601 and a coupling component 20602. The synchronous rotating component 20601 is arranged on one side of the mounting frame 201 and can drive the first calendering roller 202, the second calendering roller 203, and the third calendering roller 204 to rotate synchronously through the coupling component 20602.

[0046] In this application, the synchronous rotation assembly 20601 can use the second rotary motor 2060101 to drive three mutually meshing synchronous gears 2060102 to rotate. The coupling assembly 20602 can use a cross telescopic coupling assembly 20602. The cross telescopic coupling assembly 20602 mainly includes a cross coupling 2060201 and telescopic connecting rods 2060202. The cross couplings 2060201 are respectively arranged at one end of the first calender roll 202 and one end of the third calender roll 204. A cross coupling 2060201 is also arranged on one side of the synchronous gear 2060102 corresponding to the first calender roll 202 and the third calender roll 204. The opposite ends of the telescopic connecting rods 2060202 are respectively arranged on the cross couplings, so that no matter how the first calender roll 202 and the third calender roll 204 move, starting the second rotary motor 2060101 can drive the first calender roll 202, the second calender roll 203 and the third calender roll 204 to rotate synchronously through the synchronous gear 2060102.

[0047] Refer to Figure 1 : The unwinding module 1 includes two sets of unwinding mechanisms arranged in parallel.

[0048] The unwinding mechanism of this application can adopt the combination of an unwinding reel, a guide wheel and a tensioning assembly to realize unwinding, which is mainly the prior art.

[0049] Refer to Figure 2 : A guide wire dividing wheel 101 is arranged on one set of unwinding mechanisms close to the calendering module 2.

[0050] This application further reduces the possibility of double wire cross winding by setting the guide wire dividing wheel 101.

[0051] When the device provided by the present invention is in use, since the conveying directions of the round wires by the first calender roll 202 and the second calender roll 203 are different from the conveying directions of the round wires by the second calender roll 203 and the third calender roll 204, one set of round wires needs to be positively introduced between the first calender roll 202 and the second calender roll 203 through the guide roll assembly 207, and the other set of round wires needs to be reversely introduced between the second calender roll 203 and the third calender roll 204 through the guide pipe assembly 208. Since the layout of the round wires is realized through the pipes, the cross winding of the round wires can be avoided, so as to realize the movement of synchronous calendering of two calender rolls driven by one main shaft, reducing the volume and floor area of the calendering module 2; and since the first calender roll 202 and the third calender roll 204 are synchronously moved through the synchronous moving mechanism 205; the first calender roll 202, the second calender roll 203 and the third calender roll 204 are synchronously rotated through the synchronous rotation mechanism 206, which also reduces the volume and floor area of the calendering module 2.

[0052] The preferred embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0053] In addition, it should be noted that, in the above specific embodiments, the various specific technical features described can be combined in any appropriate manner without conflict. To avoid unnecessary repetition, the present invention will not separately describe various possible combination methods.

[0054] Furthermore, any combination can be made between the various different embodiments of the present invention as long as it does not violate the idea of the present invention, and it should also be regarded as the content disclosed by the present invention.
