[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] Reference below Figure 1 and Figure 2 The soldering device according to the first aspect of the present invention will be described in detail.

[0032] refer to Figure 1 The soldering device according to the embodiment of the present invention includes a frame 100, a welding seat 200, a welding assembly 300 and a wire feeding assembly 400.

[0033] For example, Figure 1 and Figure 2As shown, the welding seat 200 is provided on the frame 100, and the welding seat 200 is provided with a welding station 210 for carrying the terminal; the welding assembly 300 is provided on the frame 100 and is located on the upper side of the welding station 210, and the welding assembly 300 includes a first driving structure 310 and a welding head 320, and the lower end of the welding head 320 is provided with two welding protrusions 321 distributed along a preset horizontal direction, and the preset horizontal direction is the left and right direction. The two welding protrusions 321 are respectively used to weld the two core wires of the same wire respectively. Connected to the two contacts of the same terminal, the first driving structure 310 is connected to the welding head 320 and is used to drive the welding head 320 to move in the vertical direction so that the two welding protrusions 321 can approach or move away from the welding station 210; the wire feeding assembly 400 is arranged on the frame 100, and the wire feeding assembly 400 includes two wire feeding structures 410, and the two wire feeding structures 410 are respectively located on the left and right sides of the welding station 210, and the two wire feeding structures 410 are respectively used to transport tin wire to the two contacts of the supporting terminal.

[0034] It should be noted that the wire has two core wires and the terminal is provided with two contacts, and the two core wires need to be welded to the two contacts respectively. When achieving the connection between the wire and the terminal, the two core wires need to be contacted with the two contacts respectively, and then, the welding head 320 is used to accommodate the tin wire so that the tin liquid drops on the junction of the core wire and the contact, thereby achieving welding between the core wire and the contact. If a tin wire is directly placed on the terminal, and the opposite ends of the tin wire are extended to the two contacts respectively, in this case, after the welding head 320 melts the tin wire, it is certainly possible to achieve welding between the core wire and the contact. However, since there is a certain distance between the two contacts on the terminal, the part of the tin wire located between the two contacts will cause waste.

[0035] When the soldering device of this embodiment is working, the terminal can be placed in the welding station 210 of the welding seat 200, and the two contacts on the terminal are distributed in the left and right directions. The two core wires of the wire can be extended into the welding station 210 and respectively contact the two contacts. The two wire feeding structures 410 can respectively transport the tin wire to the two contacts. Under the drive of the first driving structure 310, the welding head 320 can move downward close to the welding station 210 so that the two welding protrusions 321 can respectively contact the two tin wires, so that the ends of the two tin wires are melted, thereby realizing welding between the core wires and the contacts.

[0036] It is understandable that since a wire feeding structure 410 is respectively used at the two contact points of the terminal to feed the tin wire, the supply of the tin wire is made more accurate, thereby reducing the waste of the tin wire.

[0037] It can be understood that by providing two welding protrusions 321 on the welding head 320, the two welding protrusions 321 can respectively contact the contacts on the terminal to reduce the probability of the middle part of the two contacts on the terminal contacting the welding head 320, thereby reducing the burns caused by the welding head 320 to the structure between the two contacts on the terminal.

[0038] In order to enable the wire to be automatically transported to the welding station 210 and to enable the wire to automatically leave the welding station 210, in some embodiments of the present invention, the soldering device also includes a wire conveying assembly (not shown in the figure), the wire conveying assembly includes a conveyor line and a plurality of jigs, the conveyor line extends in the left and right directions, the jigs are arranged on the conveyor line at intervals in the left and right directions, the jigs are used to load the wire, the welding seat 200 is located on the rear side of the conveyor line, and the conveyor line can drive the jig to move in the left and right directions.

[0039] Furthermore, when the soldering device of the present application is working, the wire can be loaded on the jig, and the two core wires at the rear end of the wire are exposed. Under the conveyance of the conveyor line, the jig can move from right to left, so that the jig can be moved in sequence to the front of the welding seat 200, and when the jig is located in front of the welding seat 200, the two exposed core wires on the wire loaded on the jig can be just located in the welding station 210; when the welding assembly 300 completes the welding between the core wire and the contact on the terminal, the conveyor line can be conveyed to the left for a distance to allow another jig to move to the front of the welding seat 200 to complete the welding between another wire and another terminal.

[0040] It can be understood that by setting up a wire conveying assembly, the wire conveying assembly can automatically convey the wire to the welding seat 200 and move the two core wires of the wire to the welding station 210 of the welding seat 200, thereby improving the degree of automation of the soldering device of the present application and reducing the labor intensity of the staff.

[0041] It should be noted that although the conveyor line can sequentially convey the jigs to the front of the welding seat 200,

[0042] However, as the conveyor line works for a long time, the conveying accuracy of the conveyor line for the jig becomes lower and lower, making it difficult for the jig to be located just in front of the welding seat 200. In this case, the two core wires of the wire on the jig are difficult to fall just into the welding station 210, thereby affecting the subsequent welding effect between the core wires and the contacts on the terminal.

[0043] Based on the above problems, in some embodiments of the present invention, reference Figure 1 The soldering device also includes a positioning component 500, which is arranged on one side of the welding station 210. The positioning component 500 is used to position the jig in a preset horizontal direction so that the two core wires of the wire on the jig fall completely into the welding station 210.

[0044] It can be understood that by setting up the positioning component 500, the positioning component 500 can position the jig in a preset horizontal direction, so that the jig can be located just in front of the welding seat 200, and the two core wires of the wire on the jig can both fall into the welding station 210.

[0045] In a further embodiment of the present invention, reference is made to Figure 1 and Figure 2 The positioning assembly 500 includes a positioning frame 510 and a second driving structure 520. The positioning frame 510 is located on the upper side of the conveyor line, and a positioning groove 511 is provided on the positioning frame 510. The opening of the positioning groove 511 faces downward, and the positioning groove 511 has a first positioning groove wall 511a and a second positioning groove wall 511b distributed along the left and right directions. The second driving structure 520 is connected to the positioning frame 510 and can drive the positioning frame 510 to perform lifting movements.

[0046] It can be understood that after the conveyor line transports the jig to the front of the welding seat 200, the second drive structure 520 can drive the positioning frame 510 to move downward so that the jig can be accommodated in the positioning groove 511, and the jig can be fine-tuned in the left and right directions under the first positioning groove wall 511a and the second positioning groove wall 511b, so that the jig can be located just in front of the welding seat 200, and the two core wires of the wire on the jig can fall completely into the welding station 210.

[0047] In the process of the second driver 121 driving the positioning frame 510 to perform the lifting movement, in order to enable the fixture to smoothly enter the positioning groove 511, in some embodiments of the present invention, reference is made to Figure 2 The slot of the positioning slot 511 is provided with a guide surface 511 c, and the guide surface 511 c is used to guide the fixture into the positioning slot 511.

[0048] It can be understood that by setting a guide surface 511c at the notch of the positioning groove 511, when the second driving structure 520 drives the positioning frame 510 downward to approach the jig, the jig can smoothly enter the positioning groove 511 under the guiding action of the guide surface 511c, thereby completing the positioning of the jig in the left and right directions.

[0049] It should be noted that, since the core wire has a certain flexibility, when the two core wires of the wire fall into the welding station 210, if the core wire is bent, even if the core wire is still in the welding station 210, it is difficult for the core wire to just contact the contact. In this case, even if the welding between the core wire and the contact is completed later, the connection strength between the core wire and the contact is low, and the connection between the core wire and the contact is easily disconnected due to external forces such as vibration.

[0050] Based on the above problems, in some embodiments of the present invention, reference Figure 2 The positioning frame 510 is also provided with a first clamping groove 512 and a second clamping groove 513 distributed along the left and right directions. The first clamping groove 512 and the second clamping groove 513 are both open downward. The first clamping groove 512 is used to accommodate one of the core wires of the wire, and the second clamping groove 513 is used to accommodate the other core wire of the wire.

[0051] It can be understood that, under the drive of the second driving structure 520, the positioning frame 510 can move downward so that the jig can be accommodated in the positioning groove 511, thereby realizing the positioning of the jig in the left and right directions, and the two core wires can be respectively accommodated in the first clamping groove 512 and the second clamping groove 513 to realize the positioning of the two core wires in the left and right directions, thereby enabling the two core wires to accurately contact the two contacts on the terminal in the welding station 210 respectively.

[0052] It should be noted that for different types of terminals, the positions of the contacts on the terminals are also different.

[0053] In order to enable the soldering device of the present application to complete the welding between wires and different types of terminals, in some embodiments of the present invention, reference is made to Figure 1 A third driving structure 110 is provided on the frame 100. The third driving structure 110 is connected to the welding seat 200 and is used to drive the welding seat 200 to move in the front and rear directions to approach or move away from the conveyor line.

[0054] It is understandable that the length of the core wire on the wire is certain, and for different terminals, when the terminal is located on the welding station 210, the distance between the contact on the terminal and the conveying line is different. In the soldering device of this embodiment, when the distance between the contact on the terminal and the conveying line is relatively far, the third driving structure 110 can drive the welding seat 200 close to the conveying line to reduce the distance between the contact on the terminal and the conveying line, so that the end of the wire core can smoothly contact the contact on the terminal; when the distance between the contact on the terminal and the conveying line is relatively close, the third driving structure 110 can drive the welding seat 200 away from the conveying line to increase the distance between the contact on the terminal and the conveying line, so that the end of the wire core can smoothly contact the contact on the terminal.

[0055] In some embodiments of the present invention, reference Figure 2 The wire feeding structure 410 includes a mounting block 411 and a wire guide tube 412 . The wire guide tube 412 is disposed on the mounting block 411 , and one end of the wire guide tube 412 faces the welding station 210 .

[0056] It is understandable that the tin wire can be passed through the wire guide tube 412 , and under the guidance of the wire guide tube 412 , the tin wire can be smoothly transported to the welding station 210 .

[0057] In some embodiments of the present invention, a pre-positioning station 220 is further provided on the welding seat 200, which is connected to the welding station 210 and is used to pre-position the terminal; a pushing structure 120 is further provided on the frame 100, and the pushing structure 120 includes a driver 121 and a pushing rod 122, and the driver 121 is connected to the pushing rod 122, and is used to drive the pushing rod 122 to push the terminal on the pre-positioning station 220 to the welding station 210.

[0058] For example, Figure 1 As shown, the welding seat 200 is also provided with a pre-positioning station 220, which is located on the rear side of the welding station 210; the frame 100 is also provided with a pushing structure 120, which includes a driver 121 and a pushing rod 122, the pushing rod 122 extends in the front-to-back direction, and the driver 121 is connected to the pushing rod 122.

[0059] Furthermore, the staff can use the terminal loading device to load the terminal to the pre-positioning station 220. Then, the driver 121 can drive the push rod 122 to move forward to push the terminal on the pre-positioning station 220 forward into the welding station 210, thereby realizing the loading of the terminal in the welding station 210.

[0060] The data line production line provided in accordance with the embodiment of the second aspect of the present utility model includes the soldering device provided in the embodiment of the first aspect of the present utility model.

[0061] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
