[0035] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention, and directions and references (e.g., up, down, left, right, etc.) may only be used to help describe the features in the drawings. Therefore, the following specific embodiments are not to be taken in a limiting sense, and the scope of the subject matter claimed is limited only by the attached claims and their equivalents.

[0036] like Figure 1-Figure 3 As shown, a cable inner conductor welding device includes a welding component 1, a clamping component 2 and a floating component 3:

[0037] The clamping assembly 2 is used to clamp the cable 8 and has a transmission groove 201 opening downward;

[0038] The floating assembly 3 is supported below the clamping assembly 2 and is used to shake the solder evenly when the soldering assembly 1 heats and melts the solder. The floating assembly 3 includes a cam member 301 that is rotatably arranged in the transmission groove 201 and is used to drive and cooperate with the groove wall of the transmission groove 201 to drive the clamping assembly 2 to shake horizontally, and a limiting mechanism that is used to support the clamping assembly 2 and limit its shaking amplitude. The cam member 301 is driven by a motor 308, and the motor 308 is installed on a mounting seat 307.

[0039] During welding, firstly, the inner conductor 9 is put on the end of the cable 8, and then the cable 8 is clamped by the clamping assembly 2 so that the end of the cable 8 is facing the welding assembly 1. Then the welding assembly 1 gradually approaches the cable 8 and heats and melts the solder. During this process, the motor drives the cam component 301 to rotate. During the rotation of the cam component 301, it cooperates with the groove wall of the transmission groove 201 of the clamping assembly 2 to drive the clamping assembly 2 to produce a small lateral shaking, so that the solder is evenly distributed, thereby improving the welding effect.

[0040] In some examples, the limiting mechanism includes a floating seat 302, which is arranged between the mounting seat 307 of the floating component 3 and the clamping seat 202 of the clamping component 2, and a first guide shaft 303 is installed on the clamping seat 202, and a second guide shaft 304 is installed on the mounting seat 307 to cross the first guide shaft 303. The number of first guide shafts 303 and the number of second guide shafts 304 can be but are not limited to one, two or three, etc. The floating seat 302 is sleeved on the first guide shaft 303 and the second guide shaft 304 and can slide along the first guide shaft 303 and the second guide shaft 304, and a first elastic member 305 is arranged between the floating seat 302 and the clamping seat 202, and a second elastic member 306 is arranged between the floating seat 302 and the mounting seat 307. The first elastic member 305 and the second elastic member 306 are both springs, which can play a buffering role.

[0041] In some examples, the cam component 301 is a cam bearing, a connecting shaft is provided between the output end of the motor 308 and the rod of the cam bearing, the floating seat 302 is provided with a through groove for the connecting shaft to pass through, and a floating gap is provided between the outer peripheral wall of the connecting shaft and the groove wall of the through groove to allow the floating seat 302 to produce lateral displacement.

[0042] In some examples, a carrier 4 and a lifting mechanism 5 installed on the carrier 4 and used to lift the mounting seat 307 are also included. The lifting mechanism 5 can be but is not limited to a cylinder or a telescopic rod, etc. A guide mechanism 6 is arranged between the carrier 4 and the mounting seat 307. The number of guide mechanisms 6 can be but is not limited to one group, two groups or three groups, etc. Each group of guide mechanisms 6 includes a guide rod fixed on the carrier 4, and the end of the guide rod facing away from the carrier 4 passes through the mounting seat 307, and a linear bearing is installed between the guide rod and the mounting seat 307. During welding, while the motor 308 drives the cam member 301 to rotate so that the clamping assembly 2 shakes slightly, the lifting mechanism 5 drives the clamping assembly 2 to move upward until the insulating sheet sleeved on the end of the cable abuts against the welding assembly 1. This is the limit position of the upward movement of the clamping assembly 2. Although the cable 8 is clamped and positioned by the clamping assembly 2, the hardness of the cable 8 itself is not high. When the welding assembly 1 approaches it and welds, bending and displacement may occur. By lifting the cable 8 so that the insulating sheet on it abuts against the welding assembly 1, displacement of the welding part can be avoided, thereby improving the stability of welding. In the upward movement process, the guide rod and the linear bearing cooperate to guide the movement of the clamping assembly 2.

[0043] In some examples, both ends of the clamping seat 202 are bent toward the direction of the mounting seat 307 to form a first bending portion 2021, one end of the first elastic member 305 abuts against the inner wall of the first bending portion 2021, and the other end abuts against the outer wall of the clamping seat 202, and both ends of the mounting seat 307 are bent toward the direction of the clamping seat 202 to form a second bending portion 3071, one end of the second elastic member 306 abuts against the inner wall of the second bending portion 3071, and the other end abuts against the outer wall of the mounting seat 307, the first bending portion 2021 and the second bending portion 3071 are staggered with each other, and the clamping seat 202, the mounting seat 307, the first bending portion 2021 and the second bending portion 3071 are enclosed to form a floating cavity for accommodating the floating seat 302, and the floating cavity can limit the floating distance of the floating seat 302.

[0044] In some examples, a centering mechanism 7 is further included, which is located above the clamping assembly 2 and directly opposite to it. The centering mechanism 7 includes a centering sleeve 701 with a centering cavity formed therein, and the centering cavity is used for the inner conductor 9 to be inserted to guide it, and one end of the centering cavity is blocked to form a blocking end for limiting the inner conductor 9 inserted therein; during welding, the inner conductor 9 is first sleeved on the end of the cable 8, and then the inner conductor 9 is inserted upward into the centering cavity of the centering sleeve 701 until it abuts against the blocking end, and then the cable 8 is clamped by the clamping assembly 2, so that the cable 8 can be positioned and the operation is convenient.

[0045] In some examples, the centering mechanism 7 also includes a longitudinal adjustment mechanism 702 for adjusting the longitudinal displacement of the centering sleeve 701 and a transverse adjustment mechanism 703 for adjusting the transverse displacement of the centering sleeve 701. The longitudinal adjustment mechanism 702 and the transverse adjustment mechanism 703 are both slide structures, so that the centering sleeve 701 can be positioned according to different types of cables 8 to limit the inner conductor 9; the slide includes a fixed seat, a screw nut structure installed on the fixed seat, and a sliding seat connected to the output end of the screw nut structure. The fixed seat of the longitudinal adjustment mechanism 702 is installed on the bracket, and its sliding seat is connected to the sliding seat of the transverse adjustment mechanism 703.

[0046] In some examples, there are two groups of welding assemblies 1, the two groups of welding assemblies 1 are symmetrically distributed and each group of welding assemblies 1 includes a welding head 101 and a linear reciprocating drive mechanism 102 for driving the welding head 101 to move closer to or away from the inner conductor 9. The linear reciprocating drive mechanism 102 can be but is not limited to a cylinder, which is mounted on a support plate and a slide rail 103 is mounted on the support plate. A slider 104 that cooperates with the slide rail is installed at the bottom of the welding head 101, and an insulation block 105 is installed between the slider and the welding head 101 for isolating the heat transferred from the welding head 101 to increase the life of the linear reciprocating drive mechanism 102.

[0047] In some examples, the clamping assembly 2 and the floating assembly 3 are both inclined from top to bottom toward the side close to the operating side, and the platform 4 includes a bottom plate 401, an inclined top plate 402, and a vertical plate 403 located between the bottom plate 401 and the top plate 402. A chamber for accommodating the lifting mechanism 5 is formed between the top plate 402, the bottom plate 401, and the vertical plate 403, and the top plate 402 is provided with an avoidance groove for the power supply machine 308 to pass through. The top plate 402 is inclined from top to bottom toward the side away from the operating side, so that the clamping assembly 2 and the floating assembly 3 thereon are inclined synchronously, thereby facilitating the clamping and centering of the cable 8.

[0048] In some examples, the clamping mechanism includes two wire claws 203 and a clamping cylinder 204 for driving the two wire claws 203 to move closer to or away from each other. The clamping cylinder 204 is installed on the clamping seat 202, and each wire claw 203 includes a plurality of fingers spaced apart in the longitudinal direction.

[0049] Working principle:

[0050] During welding, first, the inner conductor 9 is sleeved on the end of the cable 8, and the inner conductor 9 is inserted upward into the centering cavity of the centering sleeve 701, and then the cable 8 is clamped by the clamping assembly 2. Then, the two welding heads 101 gradually approach the cable 8 and heat the solder to melt. During this process, the lifting mechanism 5 drives the clamping assembly 2 to move up until the insulating sheet sleeved on the end of the cable abuts against the welding assembly 1. At the same time, the motor 308 drives the cam component 301 to rotate. During the rotation of the cam component 301, it cooperates with the groove wall of the transmission groove 201 of the clamping assembly 2 to drive the clamping assembly 2 and the cable 8 thereon to produce a small lateral shaking, so that the solder is evenly distributed, thereby improving the welding effect.
