[0042] Reference below Figures 1 to 4 The welding device according to the first aspect of the present application is described in detail.

[0043] refer to Figures 1 to 3 According to the first embodiment of the present invention, the welding device comprises a terminal conveying module 100, a wire positioning module 200, a terminal transfer module 300 and a welding module 400; the terminal conveying module 100 is provided with a terminal output port 111a for outputting the terminal; the wire positioning module 200 is used for clamping the wire; the terminal transfer module 300 comprises a first driving structure 310 and a terminal positioning structure 320, a material passage 321 is formed in the terminal positioning structure 320, and the material passage 321 has a first end 321a and a second end 321b opposite to each other, and the first driving structure 310 is connected to the terminal positioning structure 320, and is used to drive the terminal positioning structure 320 to do lifting and lowering. The terminal positioning structure 320 is moved to switch between the first state and the second state. When the terminal positioning structure 320 is in the first state, the first end 321a is connected to the terminal output port 111a, and the terminal conveying module 100 can convey the terminal to the second end 321b along the feeding channel 321. When the terminal positioning structure 320 is in the second state, the terminal at the second end 321b is abutted against the wire on the wire positioning module 200 in the vertical direction; the welding module 400 is arranged on one side of the wire positioning module 200. When the terminal positioning structure 320 is in the second state, the welding module 400 can weld the terminal at the second end 321b to the wire.

[0044] For example, Figures 1 to 3As shown, a material feeding channel 321 extending forward and backward is formed in the terminal positioning structure 320, the rear end of the material feeding channel 321 forms a first end 321a, and the front end of the material feeding channel 321 forms a second end 321b, the terminal conveying module 100 is arranged on the rear side of the terminal transfer module 300, the wire positioning module 200 is arranged on the front side of the terminal transfer module 300, and the welding module 400 is arranged on the upper side of the terminal transfer module 300. When the welding device of the present application is working, the first driving structure 310 drives the terminal positioning structure 320 to move downward so that the first end 321a of the feeding channel 321 is connected to the terminal output port 111a of the terminal conveying module 100. At this time, the terminal conveying module 100 can convey the terminal through the terminal output port 111a and the first end 321a in sequence into the feeding channel 321, and continue to drive the terminal to move along the feeding channel 321 to the second end 321b of the feeding channel 321. Then, the first driving structure 310 drives the terminal positioning structure 320 to move upward so that the terminal at the second end 321b is close to the wire on the wire positioning module 200, and the upper end of the terminal is in contact with the wire. Then, the welding module 400 can weld the terminal and the wire so that the terminal and the wire together form a data line.

[0045] It can be understood that during the operation of the welding device of the present application, the terminal positioning structure 320 performs lifting and lowering movements under the drive of the first driving structure 310, so that the space occupied by the terminal positioning structure 320 in the horizontal direction is smaller, so as to reduce the size of the welding device of the present application in the horizontal direction, and make the overall structure of the welding device of the present application more compact.

[0046] It can be understood that since the first driving structure 310 can drive the terminal positioning structure 320 to perform lifting and lowering movements, so that the terminal at the second end 321b can approach and abut the wire on the wire positioning module 200 in the vertical direction, the wire on the wire positioning module 200 can remain in a stationary state throughout the entire process of welding with the terminal, so as to reduce the probability of the problem of the wire being difficult to align with the terminal due to deformation of the wire due to movement, thereby improving the welding accuracy between the wire and the terminal.

[0047] In some embodiments of the present invention, reference Figure 1 and Figure 2 The terminal transfer module 300 also includes a second drive structure 330. The terminal positioning structure 320 includes a lower seat 322 and an upper seat. A material feeding channel 321 is formed between the lower seat 322 and the upper seat. The second drive structure 330 is connected to the upper seat and is used to drive the upper seat to move closer to or away from the lower seat 322 in the vertical direction.

[0048] It should be noted that when the terminal is located at the second end 321b of the feeding channel 321, the rear half of the terminal is located inside the feeding channel 321, and the front half of the terminal is located outside the feeding channel 321, and the front half of the terminal is used for welding with the wire; therefore, when the front half of the terminal is welded with the wire, the terminal and the wire together constitute the data line. Since the rear half of the terminal is still located inside the feeding channel 321, due to the limitation of the channel wall of the feeding channel 321, it is difficult for the terminal to completely detach from the feeding channel 321, which makes it difficult to unload the data line, affecting the subsequent work of the welding device.

[0049] It can be understood that in the welding device of the present embodiment, since the terminal positioning structure 320 includes a lower seat 322 and an upper seat, a feeding channel 321 is formed between the upper seat and the lower seat 322, and the second driving structure 330 is connected to the upper seat; thus, after the front half of the terminal is welded to the wire to form a data line, the second driving structure 330 can drive the upper seat upward away from the lower seat 322, at which time the feeding channel 321 is opened, and the data line can smoothly detach from the feeding channel 321, and then, the second driving structure 330 can drive the upper seat downward close to the lower seat 322 to close the feeding channel 321, at which time, the terminal positioning structure 320 can position the next terminal.

[0050] In some embodiments of the present invention, the upper seat includes an upper seat body 323 and an elastic clamping structure, a first sub-channel is defined between the lower seat 322 and the upper seat body 323, a second sub-channel is defined between the elastic clamping structure and the lower seat 322, an end of the first sub-channel away from the second sub-channel forms a first end 321a, an end of the second sub-channel away from the first sub-channel forms a second end 321b, and the elastic clamping structure is used to cooperate with the lower seat 322 to clamp the terminal located at the second end 321b.

[0051] For example, Figure 2 and Figure 3 As shown, the upper seat includes an upper seat body 323 and an elastic clamping structure connected to each other, a first sub-channel is formed between the lower seat 322 and the upper seat body 323, a second sub-channel is formed between the elastic clamping structure and the lower seat 322, the rear end of the second sub-channel is connected to the front end of the first sub-channel, the rear end of the first sub-channel forms a first end 321a, and the front end of the second sub-channel forms a second end 321b.

[0052] Furthermore, after the terminal conveying module 100 conveys the terminal into the feeding channel 321, when the terminal moves along the feeding channel 321 to the second end 321b, the elastic clamping structure can cooperate with the lower seat 322 to clamp the terminal at the second end 321b, so that the terminal can be stably positioned at the second end 321b. On the one hand, it can prevent the terminal from escaping from the feeding channel 321 under the conveying action of the terminal conveying module 100. On the other hand, the clamping and fixing of the terminal by the elastic clamping structure can enable the welding module 400 to smoothly weld the wire and the terminal, and make the welding between the terminal and the wire have higher precision.

[0053] In some embodiments of the present invention, reference Figure 3 The elastic clamping structure includes a clamping member 324 and an elastic member 325. The clamping member 324 includes a clamping portion 324a, a hinged portion 324b and a driving portion 324c which are connected in sequence. The hinged portion 324b is hinged to the upper seat body 323. A second sub-channel is formed between the clamping portion 324a and the lower seat 322. The driving portion 324c is connected to the upper seat body 323 through the elastic member 325. The elastic member 325 is used to provide an elastic force to keep the clamping portion 324a close to the lower seat 322.

[0054] It is understandable that under the elastic force of the elastic member 325, the driving portion 324c can rotate upward relative to the hinge portion 324b, so that the clamping portion 324a can rotate downward relative to the hinge portion 324b, so that the clamping portion 324a can cooperate with the lower seat 322 to clamp and fix the terminal at the second end 321b.

[0055] It can be understood that by connecting the elastic member 325 with the driving portion 324c of the clamping member 324, the elastic member 325 can be set on the side away from the clamping portion 324a, so that there is enough space for the clamping portion 324a to move; at the same time, the staff can increase the length of the driving portion 324c itself to make the clamping member 324 as a whole present the form of a force-saving lever, so that the elastic member 325 can make the clamping portion 324a have a greater clamping force on the terminal while providing a smaller elastic force.

[0056] In a further embodiment of the present invention, reference Figure 3 The hinge portion 324b is located on a side of the clamping portion 324a away from the second end 321b.

[0057] It can be understood that since the hinge portion 324b is located on the side of the driving portion 324c away from the second end 321b, during the process of the terminal moving toward the second end 321b in the second sub-channel, the terminal will push the clamping portion 324a to gradually rotate upward relative to the hinge portion 324b. Accordingly, during the process of the terminal moving toward the second end 321b in the second sub-channel, the clamping force exerted on the terminal by the clamping portion 324a will gradually increase. When the terminal moves to the second end 321b, the clamping force applied to the terminal by the clamping portion 324a reaches a maximum. At this time, the clamping portion 324a can firmly clamp the terminal at the second end 321b.

[0058] In some embodiments of the present invention, the terminal conveying module 100 includes a temporary storage seat 110, a push rod 120 and a third driving structure 130. A feeding channel 111 is formed in the temporary storage seat 110. The channel wall of the feeding channel 111 is provided with a terminal input port for allowing the terminal to enter. One end of the feeding channel 111 forms a terminal output port 111a. The push rod 120 can be slidably penetrated in the feeding channel 111. The third driving structure 130 is connected to the push rod 120 and is used to drive the push rod 120 to push the terminal in the feeding channel 111 into the second end 321b of the material passage 321.

[0059] For example, Figures 1 to 3 As shown, the terminal conveying module 100 includes a temporary storage seat 110, a push rod 120 and a third driving structure 130. A feeding channel 111 extending forward and backward is formed in the temporary storage seat 110, and a terminal output port 111a is formed at the front end of the feeding channel 111. The push rod 120 extends in the front-to-back direction and is slidably arranged in the feeding channel 111. A terminal input port is provided on the channel wall of the feeding channel 111. The third driving structure 130 is connected to the push rod 120 and is used to drive the push rod 120 to slide in the front-to-back direction.

[0060] Furthermore, when the terminal conveying module 100 of the present embodiment is working, the third driving structure 130 can drive the push rod 120 to move backward along the feeding channel 111 so that the terminal input port and the terminal output port 111a are connected. At this time, the terminal can enter the feeding channel 111 through the terminal input port, and then, the third driving structure 130 can drive the push rod 120 to move forward along the feeding channel 111. The push rod 120 pushes the terminal in the feeding channel 111 into the running channel 321 through the terminal output port 111a, and continues to push the terminal into the second end 321b of the running channel 321.

[0061] In a further embodiment of the present invention, reference Figure 1 The welding device also includes a terminal storage module, which includes a vibration disk 140 and a conveying rail 150. Terminals are stored in the vibration disk 140, and opposite ends of the conveying rail 150 are respectively connected to the vibration disk 140 and the terminal input port.

[0062] Furthermore, the vibrating bowl 140 can vibrate the terminals into the conveying rail 150, so that the terminals can move along the conveying rail 150 to the terminal input port and enter the feeding channel 111.

[0063] In some embodiments of the present invention, the welding device further includes a wire guiding module 500 for guiding the welding wire to the second end 321b.

[0064] For example, as Figure 1 and Figure 4 shown, the wire guiding module 500 includes a fourth driving structure 510, a lifting seat 520, an adjusting frame 530 and a wire guiding tube 540. The wire guiding tube 540 is arranged at one end of the adjusting frame 530, and the other end of the adjusting frame 530 is rotatably arranged on the lifting seat 520 around a horizontal axis. The fourth driving structure 510 is connected to the lifting seat 520 and is used to drive the lifting seat 520 to move up and down. A wire pressing member is also arranged on the lifting seat 520, and the wire pressing member is located directly above the wire positioning module 200.

[0065] It can be understood that after the wire is positioned on the wire positioning module 200, the fourth driving structure 510 can drive the lifting seat 520 to descend, so that the wire pressing member can press and fix the wire on the wire positioning module 200. At this time, the wire outlet of the wire guiding tube 540 is directly opposite to the end of the wire on the wire positioning module 200, and the welding wire can be accurately conveyed along the wire guiding tube 540 to the end of the wire. When the terminal positioning structure 320 is in the second state, the welding wire can be accurately conveyed along the wire guiding tube 540 to the second end 321b of the terminal positioning structure 320.

[0066] It can be understood that since the adjusting frame 530 is rotatably arranged on the lifting seat 520 around a horizontal axis, the operator can rotate the adjusting frame 530 relative to the lifting seat 520 to adjust the height of the wire guiding tube 540.

[0067] In some embodiments of the present invention, referring to Figure 1 , the welding module 400 includes a fifth driving structure 410 and a welding head 420. The welding head 420 is located directly above the second end 321b. The fifth driving structure 410 is connected to the welding head 420 and is used to drive the welding head 420 to move up and down, so that the welding head 420 approaches or moves away from the terminal on the second end 321b.

[0068] Next, referring to Figure 5 the welding method of the second aspect of the present invention will be described in detail.

[0069] According to the welding method provided by the embodiments of the second aspect of the present invention, it is applied to the welding device provided by the embodiments of the first aspect of the present invention; referring to Figure 5The welding method includes but is not limited to the following steps:

[0070] Step S100, clamping the wire on the wire positioning module 200;

[0071] Step S200, driving the terminal positioning structure 320 to descend so that the first end 321a is connected to the terminal output port 111a;

[0072] Step S300, input the terminal into the material passage 321 through the terminal output port 111a, and transport the terminal to the second end 321b along the material passage 321;

[0073] Step S400, driving the welding seat to rise so that the upper end of the terminal abuts against the wire;

[0074] Step S500: welding the upper end of the terminal to the wire material to form a data line.

[0075] It should be noted that the wire needs to be welded to the upper end surface of the terminal. After the wire is clamped on the wire positioning module 200, the wire has been positioned. The terminal positioning structure 320 is driven to descend so that the first end 321a of the terminal positioning structure 320 is connected to the terminal output port 111a. At this time, the terminal can enter the feeding channel 321 of the terminal positioning structure 320 through the terminal output port 111a, and move along the feeding channel 321 to the second end 321b. By driving the terminal positioning to rise, the terminal at the second end 321b can move upward close to the wire on the wire positioning module 200, and make the upper end surface of the terminal abut against the wire. Then, the upper end of the terminal can be welded to the wire to form a data cable.

[0076] It can be understood that since the terminal positioning structure 320 can perform lifting and lowering movements, the terminal positioning structure 320 can drive the terminal upward to abut against the wire. The wire does not need to continue moving after being positioned on the wire positioning module 200, so as to avoid deformation of the wire due to movement, thereby improving the welding accuracy between the terminal and the wire.

[0077] In a further embodiment of the present invention, reference Figure 5 The welding method also includes but is not limited to the following steps:

[0078] Step S600, driving the upper seat upward away from the lower seat 322 to open the material feeding channel 321 in the vertical direction;

[0079] Step S700, driving the data line away from the second end 321b, so that the terminal is separated from the material feeding channel 321;

[0080] Step S800: drive the upper seat downward to approach the lower seat 322 to close the material feeding channel 321 in the vertical direction.

[0081] It should be noted that after the wire and the terminal are welded to form the data line, since the terminal is located at the second end 321b of the feeding channel 321, the channel wall of the feeding channel 321 will restrict the terminal to hinder the feeding of the data line.

[0082] It can be understood that in the welding method of the present application, since the terminal positioning structure 320 includes a lower seat 322 and an upper seat, the feeding channel 321 is formed between the lower seat 322 and the upper seat, and by driving the upper seat upward away from the lower seat 322, the terminal can smoothly detach from the feeding channel 321, and then, drive the upper seat downward close to the lower seat 322 so that the feeding channel 321 is closed, and the next terminal can be smoothly fed into the feeding channel 321. At this time, the terminal positioning structure 320 can smoothly position the next terminal.

[0083] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
