Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] It should also be understood that the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include the plural forms.

[0028] It should be further understood that the term " / and" used in the specification of the present invention and the appended claims refers to any combination and all possible combinations of one or more of the related listed items, and includes these combinations.

[0029] Please refer to Figure 1 and Figure 2 , Figure 1 is a three-dimensional structural schematic diagram of the soldering mechanism 100 provided by the present invention, Figure 2 is Figure 1Schematic plan view of the soldering mechanism 100. The present invention provides a soldering mechanism 100, which includes a soldering gun 20 and a shaping component 10. The shaping component 10 is fixed on the soldering gun 20, and the solder wire is located at the position corresponding to the soldering iron tip of the soldering gun 20. Among them, the shaping component 10 is used to shape the solder wire 30, that is, to shape the straight solder wire 30 into a bent solder wire 30. When the soldering iron tip of the obliquely arranged soldering gun 20 contacts the solder wire 30, it can increase the contact area between the solder wire 30 and the soldering iron tip, thereby increasing the heating efficiency of the soldering iron tip for the solder wire 30, making more solder wire 30 become molten state to facilitate welding of the joint and the multi-core wire, and then enhancing the welding strength of the joint and the multi-core wire.

[0030] Among them, as Figure 1 and Figure 2 shown, the shaping component 10 includes a cage 11 and a shaping head 12. A guide cylinder 13 is provided on the cage 11, and the guide cylinder 13 is used to accommodate the solder wire 30; the shaping head 12 is slidably arranged on the cage 11. The shaping head 12 includes a first shaping part 121, a second shaping part 122 and a torsion spring (not shown in the figure). The first shaping part 121 and the second shaping part 122 are respectively located on opposite sides of the guide cylinder 13. One ends of the first shaping part 121 and the second shaping part 122 are rotatably connected, and the torsion spring is arranged at the rotational connection of the first shaping part 121 and the second shaping part 122, and is used to drive the other ends of the first shaping part 121 and the second shaping part 122 to approach each other; among them, the end of the first shaping part 121 facing away from the torsion spring extends in a direction away from the guide cylinder 13.

[0031] Specifically, the guide cylinder 13 is fixedly arranged on the retaining frame 11. The guide cylinder 13 is formed by a slender cylindrical column. The welding wire 30 is inserted into the inner cavity of the guide cylinder 13. The slender guide cylinder 13 can be used to guide the welding wire 30 and can shape the welding wire 30 into a straight straight strip. One end of the first shaping member 121 and the second shaping member 122 of the shaping head 12 are rotatably connected, and the other end is always kept in a clamped state under the tensioning force of the torsion spring. When the shaping head 12 moves to the position of the guide cylinder 13, the force of the guide cylinder 13 on the first shaping member 121 and the second shaping member 122 can separate the ends of the first shaping member 121 and the second shaping member 122, so that the first shaping member 121 and the second shaping member 122 are respectively located on opposite sides of the guide cylinder 13. When the shaping head 12 slides to the position of the welding wire 30 relative to the retaining frame 11, since the end of the first shaping member 121 extends in the direction away from the guide cylinder 13, the second shaping member 122 will abut the welding wire 30 and move toward the first shaping member 121, thereby making the shape of the welding wire 30 consistent with the shape of the surface of the first shaping member 121, that is, the shape of the welding wire 30 will extend in the direction away from the guide cylinder 13 to form a curved end, thereby increasing the contact area between the inclined soldering iron tip and the curved welding wire 30.

[0032] Furthermore, if Figure 1 and Figure 3 As shown, Figure 3 The diagram is a partially enlarged structural diagram of the shaping assembly 10 and the soldering iron tip in one embodiment of the present invention. The surface of the first shaping member 121 facing the guide cylinder 13 is a smooth curved surface, and the end of the second shaping member 122 away from the torsion spring is provided with a shaping wheel 123. When the shaping head 12 moves beyond the guide cylinder 13, the shaping wheel 123 is used to press the solder wire 30 to fit on the curved surface of the first shaping member 121.

[0033] The shaping wheel 123 is rotatably connected to the end of the second shaping member 122. When the shaping wheel 123 contacts the welding wire 30 for moving shaping, the shaping wheel 123 can reduce the friction between the welding wire 30 and the second shaping member 122. Furthermore, a groove 124 can be provided in the middle of the shaping wheel 123 so that the welding wire 30 is located in the groove 124. In this way, the groove 124 can be used to position and limit the welding wire 30.

[0034] Furthermore, a through hole 112 is provided on the holder 11, and the shaping assembly 10 includes a driving member 40 and a first guide rod 50, the first guide rod 50 is slidably provided in the through hole 112, one end of the first guide rod 50 is connected to the driving member 40, and the other end of the first guide rod 50 is connected to the shaping head 12. The driving member 40 is used to apply a moving force to the shaping assembly 10 through the first guide rod 50, and the through hole 112 on the holder 11 and the first guide rod 50 can make the movement of the shaping head 12 more precise.

[0035] Among them, the driving member 40 can be, for example, a servo motor or a hydraulic cylinder, etc.

[0036] In this embodiment, as Figure 2 shown, the driving member 40 includes a bracket 41, a sliding block 42, and a connecting block 43. A roller 411 is provided on the bracket 41; the sliding block 42 is slidably disposed on the bracket 41 and can move in a direction approaching or away from the roller 411; the middle of the connecting block 43 is rotatably connected to the sliding block 42, and a chute 431 is provided at one end of the connecting block 43 facing the first guide rod 50, and the end of the first guide rod 50 is slidably disposed in the chute 431.

[0037] Specifically, when the sliding block 42 moves in a direction approaching the roller 411, that is, when moving to the right as shown in Figure 2 , the connecting block 43 will abut against the roller 411 and rotate around the connection between the connecting block 43 and the sliding block 42 under the action of the roller 411, so that the end of the connecting block 43 facing the first guide rod 50 rotates downward, thereby driving the first guide rod 50 to drive the shaping head 12 to move downward, that is, to move in a direction approaching the end of the bonding wire 30, so as to abut against the bonding wire 30 and cause deformation.

[0038] Conversely, when the sliding block 42 moves in a direction away from the roller 411, that is, when moving to the left as shown in Figure 2 , the connecting block 43 will disengage from the contact with the roller 411, and the connecting block 43 will rotate around the connection between the connecting block 43 and the sliding block 42 under the action of the reset member 44, so that the end of the connecting block 43 facing the first guide rod 50 rotates upward, thereby driving the first guide rod 50 to drive the shaping head 12 to move upward, that is, to move in a direction away from the end of the bonding wire 30, so as to disengage from the contact with the bonding wire 30 and expose the bonding wire 30 for the soldering iron tip to heat the bonding wire 30.

[0039] Furthermore, as Figure 1 shown, a guide hole 421 is provided on the sliding block 42, and the shaping assembly 10 includes a second guide rod 14 and an elastic member 15. The second guide rod 14 is slidably passed through the guide hole 421. One end of the second guide rod 14 is connected to the cage 11, and the other end of the second guide rod 14 is limited to the end face of the sliding block 42 facing away from the cage 11. The elastic member 15 is sleeved on the second guide rod 14 and is elastically clamped between the sliding block 42 and the cage 11.

[0040] Specifically, one end of the second guide rod 14 facing away from the cage 11 is limited to the slider 42 by a screw. In this way, it is possible to prevent the cage 11 from being overly withdrawn relative to the slider 42. Moreover, when the driving member 40 drives the cage 11 to move towards the slider 42, the second guide rod 14 will not interfere with the movement of the cage 11. By sleeving an elastic member 15 on the second guide rod 14, the cage 11 can be kept at a certain distance from the slider 42 as much as possible, and when the cage 11 moves towards the slider 42, a certain buffer can be provided to prevent the cage 11 from colliding with the slider 42.

[0041] Optionally, the elastic member 15 can be a spring, a shrapnel or a foam, etc.

[0042] Furthermore, as Figure 4 shown, Figure 4 FIG. is a schematic three-dimensional structure diagram of a soldering mechanism 100 in another embodiment of the present invention. The shaping assembly 10 and the corresponding soldering gun 20 form a set of welding units for welding a core wire and a corresponding joint. In order to improve the working efficiency of the soldering mechanism 100, it can be set that the soldering mechanism 100 includes a mounting plate 60, and the number of welding units is multiple groups, and the multiple groups of welding units are evenly spaced around the circumference of the mounting plate 60. In this way, the multiple groups of welding units can work simultaneously to improve the welding efficiency of the joint and the multi-core wire.

[0043] Among them, a plurality of scales can be preset on the mounting plate 60, and a plurality of assembly holes 61 are provided at the positions of the scales. The scales are used to mark the setting positions of the welding units, and the assembly holes 61 are used to assemble the welding units.

[0044] For example, the scale can include 3 heads, 4 heads, 5 heads or 6 heads. The 3-head scale is used to identify the position of the welding unit that needs to be installed when welding three core wires. Therefore, the assembly holes 61 corresponding to the 3-head scale are evenly spaced around the circumference of the mounting plate 60, and the central angle between adjacent assembly holes 61 is 120 degrees. The assembly holes 61 corresponding to the 4-head scale are evenly spaced around the circumference of the mounting plate 60, and the central angle between adjacent assembly holes 61 is 90 degrees. By pre-processing the scales and the assembly holes 61 on the mounting plate 60, the fixing steps of the welding units can be simplified, and the assembly efficiency of the welding units can be improved.

[0045] Furthermore, as Figure 5 and Figure 6 shown, Figure 5 FIG. is a schematic three-dimensional structure diagram of a soldering mechanism 100 in yet another embodiment of the present invention, Figure 6 is Figure 5Schematic diagram of the partial enlarged structure. The soldering mechanism 100 includes a wire feeding component 70. The wire feeding component 70 is arranged at the center of the mounting plate 60 and is used for clamping the joint. In this way, it is convenient for soldering the joint and can improve the automation degree of the soldering mechanism 100.

[0046] Optionally, the wire feeding component 70 can be, for example, a manipulator or the like. As Figure 7 and Figure 8 shown, Figure 7 is a three-dimensional structure schematic diagram of the wire feeding component 70 in an embodiment of the present invention, Figure 8 is Figure 7 a planar structure schematic diagram of the wire feeding component 70. The wire feeding component 70 includes a support block 71, a moving cylinder 72, a mounting head 73 and two clamping jaws 74. The moving cylinder 72 is arranged on the support block 71; the mounting head 73 is connected to the output end of the moving cylinder 72 and is used to move along the first direction under the drive of the moving cylinder 72. Two guiding grooves 731 are arranged on the mounting head 73, and the extending direction of the guiding grooves 731 is inclined with respect to the first direction; the two clamping jaws 74 are slidably arranged on the support block 71 along the second direction perpendicular to the first direction, the first ends of the two clamping jaws 74 are slidably arranged in the corresponding guiding grooves 731, and the second ends of the two clamping jaws 74 form a clamping gap for clamping the joint.

[0047] Specifically, a through hole is arranged on the support block 71, the moving cylinder 72 is fixed on one side of the support block 71, the mounting head 73 is arranged on the other side of the support block 71, and the output end of the moving cylinder 72 passes through the through hole on the support block 71 and is connected to the mounting head 73 to drive the mounting head 73 to move in a direction close to or away from the support block 71, that is, along the first direction.

[0048] Among them, in this embodiment, the wire feeding component 70 can be arranged along the axis direction of the mounting plate 60 so that the included angles between the multiple welding units surrounding the wire feeding component 70 and the joint are all the same. At this time, the first direction is the axis direction of the mounting plate 60. And further, the first direction can be set as the vertical direction.

[0049] Furthermore, as Figure 7 shown, a slider 711 protrudes on the support block 71, a guiding groove 741 is arranged on the clamping jaw 74, and the slider 711 is inserted into the guiding groove 741 to slidably connect the clamping jaw 74 and the support block 71. Among them, the extending directions of the slider 711 and the guiding groove 741 are along the second direction perpendicular to the first direction, that is, when the first direction is the vertical direction, the second direction is the horizontal direction.

[0050] Optionally, the cross-sectional shapes of the guide groove 741 and the slider 711 can be set as dovetail shapes. In this way, the two jaws 74 can be held on the support block 71 by the shapes of the slider 711 and the guide groove 741, and positioning can be performed by using the slider 711 and the guide groove 741, so as to simplify the structure of the wire feeding assembly 70 and improve the assembly efficiency of the wire feeding assembly 70.

[0051] Furthermore, the two guide grooves 731 can be symmetrically arranged with respect to the first direction, so that the jaws 74 connected in the two guide grooves 731 move synchronously. The specific meaning that the extending direction of the guide groove 731 is inclined with respect to the first direction is that the included angle between the extending direction of the guide groove 731 and the first direction is an acute angle. Thus, when the mounting head 73 moves along the first direction, the distance between the two jaws 74 will change with the distance between the two guide grooves 731, so as to adjust the distance between the two jaws 74 and facilitate the adaptation to connectors of different sizes.

[0052] Optionally, in this embodiment, as Figure 8 shown, in the direction away from the support block 71, the distance between the two guide grooves 731 gradually increases. When the moving cylinder 72 drives the mounting head 73 to move downward, the first ends of the two jaws 74 will move upward relative to the mounting head 73. At this time, the distance between the two jaws 74 becomes smaller, for clamping a connector with a smaller diameter. When the moving cylinder 72 drives the mounting head 73 to move upward, the first ends of the two jaws 74 will move downward relative to the mounting head 73. At this time, the distance between the two jaws 74 becomes larger, for clamping a connector with a larger diameter.

[0053] Furthermore, as Figure 5 shown, the soldering mechanism 100 can further include a base 80 and a lifting driving member 90. The lifting driving member 90 is fixed on the base 80, and the output end of the lifting driving member 90 is connected to the mounting plate 60, so as to drive the mounting plate 60 to perform a lifting motion, so as to move the soldering unit to the corresponding positions of the connector and the multi-core wire.

[0054] Since the lifting driving member 90 and the base 80 are arranged on one side of the mounting plate 60, when the weight of the soldering unit is large, it is easy to cause the soldering mechanism 100 to tip over.

[0055] Therefore, in this embodiment, the soldering mechanism 100 may further be provided with a third guide rod 81. A guide hole 82 may be provided on the base 80. The third guide rod 81 is inserted into the guide hole 82, and one end of the third guide rod 81 is connected to the mounting plate 60. Since the third guide rod 81 is connected to a position near the center of the mounting plate 60, the gravity of the mounting plate 60 can be balanced, preventing the soldering mechanism 100 from tipping over and improving the stability of the soldering mechanism 100. Also, a double-point connection structure can be formed between the mounting plate 60 and the base 80 to prevent the mounting plate 60 from rotating relative to the base 80 and damaging the lifting drive member 90.

[0056] Further, as Figure 5 shown, the soldering mechanism 100 may further include a translation drive member 91. The translation drive member 91 is connected to the base 80 and is used to drive the base 80 to move horizontally to adjust the position of the mounting plate 60 in the horizontal direction.

[0057] Based on the soldering mechanism 100 in the above embodiment, as Figure 9 shown, Figure 9 is a schematic three-dimensional structure diagram of a soldering device 00 in another embodiment of the present application. The present application also provides a soldering device 00. The soldering device 00 includes a positioning assembly 200 and a soldering mechanism 100. The positioning assembly 200 is correspondingly arranged with the soldering gun 20. The positioning assembly 200 is used to position the multi-core wire, and the soldering gun 20 is used to melt the solder wire 30 on the shaping assembly 10 to weld and connect the joint and the multi-core wire.

[0058] The above are only the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
