Description

Technical Field

[0001] This application relates to the technical field of connector welding, and particularly to a connector welding auxiliary device. Background Art

[0002] A coaxial cable consists of a hollow outer cylindrical conductor and an inner conductor located on the central axis. The inner conductor is separated from the cylindrical conductor and the outside by an insulating material. According to the different transmission frequency bands, coaxial cables can be divided into two types: baseband coaxial cables and broadband coaxial cables. A BNC connector is a connector used for coaxial cables. Since a coaxial cable is a shielded cable, it has the advantages of long transmission distance and stable signal. Currently, coaxial cable connectors are still widely used in communication systems. For example, the E1 interface in network equipment is connected by two coaxial cables with BNC connectors.

[0003] During the use of coaxial cables, they often need to be welded with connectors to form cable assemblies for different scenarios. There are mainly two existing welding processes for cable core wires and connectors. One is automated production, which is applicable to cable assemblies with general specifications and large production demands; the other is manual welding by workers, which is applicable to cable assemblies with special specifications and small production demands. The specific equipment is that two columns are respectively provided with a welding pen at one end close to each other, and the position of the welding pen can be adjusted, so as to clamp cable core wires of different thicknesses. During welding, the worker places the insertion part of the cable core wire and the connector between the two welding pens, and clamps the connection part of the cable core wire and the connector with the tips of the two welding pens. Then, one hand holds the cable core wire, and the other hand holds the pre-cut solder wire and places it at the connection part of the cable core wire and the connector for welding work. The quality of manual welding requires high personal skills and experience of workers. When a novice or an inexperienced worker holds the hand-held solder wire for welding, it is very easy to cause poor welding quality at the connection part of the cable core wire and the connector due to hand shaking. Summary of the Invention

[0004] This application provides a connector welding auxiliary device, which can assist workers in steadily holding the solder wire for welding operations when welding cable core wires and connectors, thereby ensuring the welding quality of cable core wires and connectors.

[0005] The above object of this application is achieved by the following technical solutions:

[0006] A connector welding auxiliary device, comprising a support plate, above which a solder wire straightening column is provided. The lower side of the solder wire straightening column is connected to a support column through an adjusting mechanism, and the adjusting mechanism can adjust the angle of the up-and-down swing of the solder wire straightening column; the lower end of the support column is slidably connected to a track, and the sliding direction is perpendicular to the axis of the welding pen. The track is arranged in parallel above the support plate, and the lower end of the track is connected to the support plate through a connecting rod; a through hole is provided along the length direction inside the solder wire straightening column, and a solder wire fixing frame is provided on one side of the solder wire straightening column close to the welding pen. A plurality of fixing units are arranged inside the solder wire fixing frame, and the fixing units can fix the solder wire inside the solder wire fixing frame. The solder wire fixing frame is connected to the solder wire straightening column through a position adjusting unit, and the distance between the solder wire fixing frame and the solder wire straightening column can be adjusted through the position adjusting unit.

[0007] Further, the fixing unit includes an installation groove, which is fixedly connected to the inner wall of the solder wire fixing frame. The notch of the installation groove faces the solder wire inside the solder wire fixing frame. A clamping block is arranged between the installation groove and the solder wire inside the solder wire fixing frame. One end of the clamping block is sleeved on a rotating shaft at the notch of the installation groove, and the clamping block is hinged to the installation groove through the rotating shaft. The length of the clamping block is greater than the distance between the rotating shaft and the solder wire inside the solder wire fixing frame. One end of the clamping block close to the solder wire inclines towards the welding pen direction, and a torsion spring is sleeved on the rotating shaft. The elastic force of the torsion spring can make one end of the clamping block close to the solder wire abutt against the surface of the solder wire.

[0008] Further, the position adjusting unit includes a driving block. One end of the driving block is fixedly connected to the solder wire fixing frame, and the other end of the driving block is rotatably connected to one end of a first threaded rod. The other end of the first threaded rod passes through a baffle and is threadedly connected to the baffle. The baffle is fixedly connected above one end of the solder wire straightening column far from the solder wire fixing frame, and the lower side of the driving block is slidably connected to the upper side of the solder wire straightening column.

[0009] Further, two parallel guide rods are arranged between the lower end of the solder wire fixing frame and the solder wire straightening column. One end of the guide rod is inserted into the solder wire straightening column and is slidably connected to the solder wire straightening column, and the other end of the guide rod is fixedly connected to the solder wire fixing frame through a fixing block.

[0010] Further, the adjusting mechanism includes two first hinge rods. The upper ends of the two first hinge rods are fixedly connected to the lower side of the tin wire straightening column. The upper end of the second hinge rod is located in the gap between the two first hinge rods. The lower end of the second hinge rod is fixedly connected to the support column. A fastening bolt is provided through the upper end of the second hinge rod, and both ends of the fastening bolt respectively penetrate through the two first hinge rods. One end of the fastening bolt is sleeved with a fastening nut and the two are threadedly connected.

[0011] Further, a knob is provided at one end of the fastening bolt.

[0012] Further, the lower end of the connecting rod is fixedly connected to the support plate. The upper end of the connecting rod is rotatably connected to the lower side of the track near the welding pen. The axis of the connecting rod during rotation passes vertically through the center point of the connector during welding.

[0013] Further, a tin wire reel bracket is provided on the support plate. A placement platform is sleeved on the upper end of the tin wire reel bracket and the two are fixedly connected.

[0014] Further, a second threaded rod is provided on one side of the welding pen relative to the support column. The lower end of the second threaded rod is fixedly connected to the support plate. A support frustum is sleeved on the second threaded rod and the two are threadedly connected.

[0015] Further, a limiting groove is provided on the upper side at the edge of the support frustum.

[0016] In summary, the present application includes at least one of the following beneficial technical effects:

[0017] 1. After the tin wire sequentially passes through the through holes in the tin wire straightening column of the present application and the tin wire fixing frame, the end portion thereof can be fixed by a plurality of fixing units in the tin wire fixing frame. Then, the angle of the tin wire straightening column is adjusted by the adjusting mechanism so that it can contact the connection portion between the connector and the cable core wire when moving along the track during welding. After adjusting the angle of the tin wire fixing column, the worker can insert the end portion of the cable core wire into the connector and hold it with one hand. Then, move the support column along the track until the tin wire fixed in the tin wire fixing frame contacts the portion to be welded of the cable core wire and the connector. At this time, the tin wire will melt under the action of the welding pen and automatically fill the portion to be welded of the cable core wire and the connector. During the welding process, since the fixing units in the tin wire fixing frame fix the tin wire, compared with the existing manual welding process where the worker holds the tin wire for welding, the tin wire in the present application will not easily shake during the welding process. Even if the operator is a novice, the tin wire can remain stable during the welding process after adjusting the angle of the tin wire, thus ensuring the welding quality of the joint and the cable core wire.

[0018] 2. When the solder wire passes through the centers of multiple fixing units of the present application, the solder wire will push the clamping block in the fixing unit towards the soldering pen direction. The clamping block will rotate towards the soldering pen direction along the rotating shaft while squeezing the torsion spring. In this way, during the soldering process, when the length of the solder wire is insufficient, the worker can drag the solder wire towards the soldering pen direction to supplement the solder wire required for soldering. After the movement is completed, the clamping block will, under the action of the elastic force of the torsion spring, reposition the clamping block against the solder wire to fix it. At the same time, when the solder wire moves in the direction away from the soldering pen, it will generate a force on the clamping block in the same direction as its movement. When this force acts on the clamping block, it will generate a tendency for the clamping block to rotate in the direction away from the soldering pen. Since the length of the clamping block of the present application is greater than the distance between the rotating shaft and the solder wire in the solder wire fixing frame, the solder wire in the solder wire fixing frame will hold the clamping block, and at the same time, the clamping block will also prevent the solder wire from moving in the direction away from the soldering pen. The clamping block of the present application can prevent the position of the solder wire from changing during the sliding process of the support column, facilitating the soldering work of the worker.

Detailed implementation manners

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts also belong to the scope of protection of the present application.

[0028] As Figure 2 、 Figure 3 、 Figure 4 and Figure 6 shown, a connector welding auxiliary device disclosed in the present application includes a support plate 1. Above the support plate 1, there is a solder wire straightening column 2. The lower side of the solder wire straightening column 2 is connected to a support column 4 through an adjusting mechanism 3. The adjusting mechanism 3 can adjust the angle of the up-and-down swing of the solder wire straightening column 2; the lower end of the support column 4 is slidably connected to a track 5, and the sliding direction is perpendicular to the axis of the soldering pen 19. The track 5 is arranged in parallel above the support plate 1, and the lower end of the track 5 is connected to the support plate 1 through a connecting rod 6; a through hole 7 is provided in the solder wire straightening column 2 along the length direction. On the side of the solder wire straightening column 2 close to the soldering pen 19, there is a solder wire fixing frame 8. Inside the solder wire fixing frame 8, there are a plurality of fixing units 9. The fixing units 9 can fix the solder wire in the solder wire fixing frame 8. The solder wire fixing frame 8 is connected to the solder wire straightening column 2 through a position adjusting unit 10. The distance between the solder wire fixing frame 8 and the solder wire straightening column 2 can be adjusted through the position adjusting unit 10.

[0029] In the above embodiments, as Figure 1 shown, in the existing manual welding equipment, two columns are symmetrically arranged on the support plate 1. On the sides of the two columns close to each other, there is a soldering pen 19 each. The axial position of the soldering pen 19 can be adjusted, so as to adapt to the connection parts of cable cores and connectors with different diameters. The existing manual welding equipment is the prior art, and its specific structure and principle will not be elaborated here.

[0030] The solder wire on the solder wire reel can continue to extend forward under the guidance of the solder wire straightening column 2, and then pass through the central positions of a plurality of fixing units 9 in the solder wire fixing frame 8. The diameter of the through hole 7 inside the solder wire straightening column 2 is similar to the diameter of the solder wire. During the process of the solder wire moving along the through hole 7, the through hole 7 can play a certain role in straightening the solder wire. In this way, the solder wire passing through the through hole 7 is not only easier to pass through the central positions of the plurality of fixing units 9, but also the straight solder wire is convenient for the subsequent workers to quickly align the parts to be welded. The adjusting mechanism 3 can adjust the swing angle of the solder wire straightening column 2 up and down. Since the solder wire straightening column 2 is connected to the solder wire fixing frame 8 through the position adjusting unit 10, and the solder wire coming out of the solder wire straightening column 2 is fixed in the solder wire fixing frame 8 by the fixing unit 9, when the adjusting mechanism 3 adjusts the up and down swing of the solder wire straightening column 2, the solder wire in the solder wire fixing frame 8 can also swing up and down. During the welding process, the solder wire can be swung up and down to evenly weld the upper and lower areas at the connection between the cable core wire and the connector. When the lengths of the connectors are different, the positions at the connections between the connectors and the cable core wires will also change in the vertical direction. At this time, by swinging the angle of the solder wire for welding up and down, the position change at the connection between the connector and the cable core wire can be adapted.

[0031] The track 5 provided in this application can obtain the supporting force from the support plate 1 through the connecting rod 6. When welding is required, the tips of the two welding pens 19 are in a state of clamping the connection between the connector and the cable core wire at this time. When the worker slides the support column 4 along the track 5, the solder wire will gradually approach the midpoint of the line connecting the tips of the two welding pens 19. When the end of the solder wire contacts the position to be welded between the connector and the cable core wire, the welding work can begin. During the welding process, since the solder wire will be consumed, the worker can continue to move the support column 4 to keep the solder wire in close contact with the connector and the cable core wire. After the welding is completed, the worker can drive the support column 4 away from the welding pen 19, so that the solder wire is separated from the welding part. The worker can complete the adjustment of the solder wire position by moving the support column 4 along the track 5. And the solder wire is fixed by the fixing unit 9. Compared with the situation where the worker holds the solder wire in the prior art, the equipment in this application reduces the problem that the worker's hand shakes during the welding process and affects the welding quality. And the moving distance and welding angle of the solder wire can be accurately controlled. Compared with controlling the welding effect by feeling when holding the solder wire by hand, this application is more convenient for new workers to quickly start welding operations.

[0032] Further, as Figure 4 and Figure 5As shown in the figure, the fixing unit 9 includes an installation groove 91, which is fixedly connected to the inner wall of the solder wire fixing frame 8. The notch of the installation groove 91 faces the solder wire inside the solder wire fixing frame 8. A clamping block 92 is arranged between the installation groove 91 and the solder wire inside the solder wire fixing frame 8. One end of the clamping block 92 is sleeved on a rotating shaft 93 at the notch of the installation groove 91. The clamping block 92 is hinged to the installation groove 91 through the rotating shaft 93. The length of the clamping block 92 is greater than the distance between the rotating shaft 93 and the solder wire inside the solder wire fixing frame 8. One end of the clamping block 92 close to the solder wire is inclined towards the soldering pen 19. A torsion spring 94 is sleeved on the rotating shaft 93, and the elastic force of the torsion spring 94 can make one end of the clamping block 92 close to the solder wire abut against the surface of the solder wire.

[0033] In the above embodiments, the clamping block 92 of the present application is hinged to the installation groove 91 through the rotating shaft 93, so that the clamping block 92 can swing around the axis of the rotating shaft 93. The length of the clamping block 92 is not only greater than the distance between the rotating shaft 93 and the solder wire inside the solder wire fixing frame 8, but also inclined towards the soldering pen 19 under the restriction of the torsion spring 94. When the solder wire moves towards the soldering pen 19, the solder wire will drive the clamping block 92 to squeeze the torsion spring 94 and swing towards the soldering pen 19 together. At this time, the clamping block 92 will not restrict the movement of the solder wire. When the length of the solder wire for soldering is insufficient, the worker can drag the solder wire towards the soldering pen 19 to supplement the required length of the solder wire. When the solder wire moves away from the soldering pen 19, the solder wire will generate a force on the clamping block 92 in contact with it, which makes the clamping block 92 swing away from the soldering pen 19. At this time, the clamping block 92 will be blocked by the solder wire and unable to rotate due to the restriction of its length. At the same time, the clamping block 92 will also restrict the movement of the solder wire. In this way, during the process of moving the support column 4, if the solder wire wants to move automatically towards the soldering pen 19, it needs to overcome the elastic force of the torsion spring 94. If it wants to move away from the soldering pen 19, it will be restricted by the clamping block 92 in contact with it. This can further ensure that the position of the solder wire will not change easily during the process of moving the solder wire, which is convenient for the worker to perform soldering. At the same time, as long as the force of dragging the solder wire is greater than the elastic force of the torsion spring 94, the clamping block 92 will not restrict the movement of the solder wire, which is convenient for the operation of supplementing the solder wire after the solder wire is consumed to a certain extent during the soldering process.

[0034] Furthermore, as Figure 6 shown, the position adjustment unit 10 includes a driving block 101. One end of the driving block 101 is fixedly connected to the solder wire fixing frame 8. The other end of the driving block 101 is rotatably connected to one end of the first threaded rod 102. The other end of the first threaded rod 102 passes through the baffle 103 and is threadedly connected therebetween. The baffle 103 is fixedly connected above the end of the solder wire straightening column 2 far from the solder wire fixing frame 8. The lower side of the driving block 101 is slidably connected to the upper side of the solder wire straightening column 2.

[0035] In the above embodiments, during the welding process, the worker rotates the first threaded rod 102. The first threaded rod 102 can drive the driving block 101 rotatably connected thereto to slide along the solder wire straightening column 2, thereby driving the solder wire fixing frame 8 to move. When the solder wire at the front end of the solder wire fixing frame 8 is consumed to a certain extent and it is inconvenient for the worker to operate, the worker can first drive the first threaded rod 102 to make the driving block 101 drive the solder wire fixing frame 8 to move towards the solder wire straightening column 2. At this time, the clamping block 92 will swing in the opposite direction. When the length extending out of the solder wire fixing frame 8 meets the requirements, stop rotating the first threaded rod 102. When the length of the solder wire between the solder wire straightening column 2 and the solder wire fixing frame 8 is also short, at this time, the first threaded rod 102 can be rotated to drive the solder wire fixing frame 8 to move towards the soldering pen 19. At this time, the clamping block 92 will drive the solder wire to move together under the restriction of the solder wire, so as to achieve the effect of dragging and supplementing the solder wire towards the soldering pen 19, making the welding process of the worker more convenient. A handle can be installed at the end of the first threaded rod 102, so that it is convenient for the worker to rotate the first threaded rod 102 comfortably and labor-savingly.

[0036] Further, as Figure 4 shown, two parallel guide rods 11 are provided between the lower end of the solder wire fixing frame 8 and the solder wire straightening column 2. One end of the guide rod 11 is inserted into the solder wire straightening column 2 and is slidably connected therebetween. The other end of the guide rod 11 is fixedly connected to the solder wire fixing frame 8 through a fixing block 12.

[0037] In the above embodiments, the guide rod 11 provided in the present application is arranged on the opposite side of the position where the solder wire fixing frame 8 is connected to the driving block 101. In this way, during the process of the worker driving the solder wire fixing frame 8 through the driving block 101, the guide rod 11 can make the upper and lower sides of the solder wire fixing frame 8 receive relatively reasonable forces and reduce the situation of shaking during its movement.

[0038] The length of the guide rod 11 of the present application is not less than the length of the driving block 101. At the same time, one end of the guide rod 11 away from the solder wire fixing frame 8 is inserted into the solder wire straightening column 2 and is slidably connected therebetween. In this way, when the position of the solder wire fixing frame 8 changes, the guide rod 11 can synchronously extend out of or enter the solder wire straightening column 2 to adapt to the position change between the solder wire fixing frame 8 and the solder wire straightening column 2.

[0039] Further, as Figure 2 and Figure 3As shown in the figure, the adjusting mechanism 3 includes two first hinge rods 31. The upper ends of the two first hinge rods 31 are fixedly connected to the lower side of the solder wire straightening column 2. The upper end of the second hinge rod 32 is located in the gap between the two first hinge rods 31. The lower end of the second hinge rod 32 is fixedly connected to the support column 4. A fastening bolt 33 is provided through the upper end of the second hinge rod 32, and both ends of the fastening bolt 33 respectively penetrate through the two first hinge rods 31. One end of the fastening bolt 33 is sleeved with a fastening nut 34 and the two are threadedly connected.

[0040] In the above embodiments, when the worker loosens the fastening nut 34 on the fastening bolt 33 of the present application, the fastening bolt 33 of the present application can act as a hinge shaft between the first hinge rod 31 and the second hinge rod 32. At this time, the worker can swing the solder wire straightening column 2 with the fastening bolt 33 as the rotation center, so as to change the inclination angle of the end of the solder wire used for welding at the end. When the adjustment reaches the appropriate angle, the worker only needs to tighten the fastening nut 34 on the fastening bolt 33. At this time, the fastening nut 34 will tightly clamp the second hinge rod 32 by the two first hinge rods 31, so as to fix the position of the solder wire straightening column 2 by using the friction force between the two. When the worker needs to readjust the angle of the solder wire for welding, only loosen the fastening nut 34 until the solder wire straightening column 2 can rotate again. The operation process is simple and convenient.

[0041] Furthermore, as Figure 6 shown, a knob 13 is provided at one end of the fastening bolt 33.

[0042] In the above embodiments, one end of the fastening bolt 33 away from the fastening nut 34 is set as the knob 13. The diameter of the knob 13 is much larger than the diameter of the fastening bolt 33 and anti-slip textures are provided on the peripheral side. In this way, when the worker adjusts the rotation angle of the solder wire straightening column 2, it is more labor-saving to hold the fastening bolt 33 and prevent it from slipping.

[0043] Furthermore, as Figure 6 shown, the lower end of the connecting rod 6 is fixedly connected to the support plate 1. The upper end of the connecting rod 6 is rotatably connected to the lower side of the track 5 near the welding pen 19. The axis of rotation of the connecting rod 6 passes through the center point of the connector during welding in the vertical direction.

[0044] In the above embodiments, since the track 5 of the present application is rotatably connected to the connecting rod 6, the worker can swing left and right with the center of the connecting rod 6 as the rotation point during the welding process. Moreover, no matter where the support column 4 moves to on the track 5, when the worker holds the support column 4 and swings left and right, the center is the center point of the connector during welding. In this way, during the welding process, when the solder wire swings with the support column 4, the end near the connector can be welded on the periphery of the position where the connector and the cable core wire need to be welded, ensuring that the molten solder after melting the solder wire can fully cover the connection between the connector and the cable core wire and guaranteeing the welding quality.

[0045] Further, as Figure 6 shown, a solder wire reel bracket 14 is provided on the support plate 1, and a placement platform 15 is sleeved on the upper end of the solder wire reel bracket 14 and the two are fixedly connected.

[0046] In the above embodiments, after the hole in the center of the solder wire reel passes through the upper end of the solder wire reel bracket 14, the solder wire reel can be placed on the placement platform 15. The height at which the placement platform 15 holds up the solder wire reel should be similar to the height of the end of the solder wire straightening post 2 away from the soldering pen 19, so that the solder wire on the solder wire reel can smoothly pass into the solder wire straightening post 2. The diameter of the solder wire reel bracket 14 is slightly smaller than the diameter of the center hole of the solder wire reel, so that when dragging the solder wire during the soldering process, the solder wire can drive the solder wire reel to rotate around the solder wire reel bracket 14 on the placement platform 15.

[0047] Further, as Figure 2 shown, a second threaded rod 16 is provided on the side of the soldering pen 19 opposite to the support column 4. The lower end of the second threaded rod 16 is fixedly connected to the support plate 1, and a support frustum 17 is sleeved on the second threaded rod 16 and the two are threadedly connected.

[0048] In the above embodiments, the support frustum 17 can be used to place the connector. Since the length specifications of the connectors are different, the distance between the connection point of the connector and the cable core wire and the tip of the soldering pen 19 is also different. By rotating the support frustum 17 on the second threaded rod 16, the position of the support frustum 17 on the second threaded rod 16 can be adjusted, so that the height of the connector placed on the support frustum 17 can be adjusted to support the connection point to be soldered between the cable core wire and the two soldering pens 19.

[0049] Further, as Figure 2 shown, a limiting groove 18 is provided on the upper side of the edge of the support frustum 17.

[0050] In the above embodiments, the shape of the limiting groove 18 on the support frustum 17 matches the shape of the connector and can be used to place the connector. In this way, during the soldering process, the connector placed in the limiting groove 18 will not easily shake, facilitating the soldering work of the worker. A plurality of limiting grooves 18 are evenly arranged along the circumferential side of the support frustum 17. In this way, when rotating the support frustum 17 to adjust its height, it can be ensured that there is always a limiting groove 18 that can hold the position to be soldered between the connector and the cable core wire between the two soldering pens 19.

[0051] The implementation principle of this embodiment is as follows: Before the worker performs welding, first place the connector on one of the limiting grooves 18, then rotate the supporting frustum 17 to adjust the height of the connection between the connector and the cable core wire to meet the requirement of being clamped by the two welding pens 19. Then place the connector in the limiting groove 18 below the middle position between the two welding pens 19. At this time, the position to be welded between the connector and the cable core wire is exactly located between the two welding pens 19. The worker continues to adjust the positions of the two weldings so that their pen tips clamp the position to be welded at the connection between the connector and the cable core wire.

[0052] Then the worker pinches the free end of the solder wire reel on the solder wire reel support 14, and pulls the solder wire through the centers of the multiple clamping blocks 92 in the solder wire straightening column 2 and the solder wire fixing frame 8 in sequence. At this time, the worker can first drive the first threaded rod 102 to rotate, and then make the driving block 101 drive the solder wire fixing frame 8 to move the solder wire towards the welding pen 19 with the clamping blocks 92. At this time, during the process that the solder wire moves towards the welding pen 19 along the through hole 7 in the solder wire straightening column 2 under the drag of the clamping blocks 92, it will be straightened. After the solder wire is dragged out of the solder wire straightening column 2 by a certain distance, the worker can assist the end of the solder wire with his hand and rotate the first threaded rod 102 again to make the solder wire fixing frame 8 move towards the solder wire straightening column 2. At this time, the solder wire will hang outwards for a certain distance from the side of the solder wire fixing frame 8 close to the welding pen 19, and this distance should at least meet the welding requirement of a single connector.

[0053] After adjusting the length of the solder wire extending out of the solder wire fixing frame 8, the worker then loosens the fastening nut 34 and adjusts the swinging angle of the solder wire straightening column 2 up and down to ensure that the solder wire can be aligned with the position to be welded at the connection between the connector and the core wire cable during welding. After adjustment, tighten the fastening nut 34 to fix the adjusted angle.

[0054] Next, the welding operation can be carried out. The worker holds the core wire cable above the connector with one hand and holds the support column 4 with the other hand to move it towards the connector. When the end of the solder wire touches the position to be welded, the solder wire will melt under the high temperature of the soldering pen 19. Since the connection between the connector and the core wire cable is generally not too thick, the melted solder liquid will automatically spread to the periphery of the position to be welded and wrap it up. The specific amount of solder wire used is determined according to the actual process. During the welding process, the solder wire will be consumed. The worker can ensure that the solder wire is always in contact with the position to be welded by continuously pushing the support column 4 along the track 5 towards the soldering pen 19. If the wrapping effect of the solder liquid at the connection between the connector and the core wire cable to be welded is not good, the support column 4 can be rotated along the connecting rod 6 to improve the welding effect of the solder liquid in the circumferential direction at the connection between the connector and the core wire to be welded. For the welding effect in the height direction, the fastening nut 34 can be loosened and the solder wire can be swung up and down to ensure the welding effect. Even if the position to be welded between the connector and the core wire cable is relatively thick, so that it is impossible to weld evenly by rotating the solder wire along the connecting rod 6, the worker can loosen the soldering pen 19 at this time and adjust the connection position to repair the position that has not been welded.

[0055] After the connection between a connector and the core wire cable is welded, the worker retracts the support column 4 along the track 5, and then turns the first threaded rod 102 to drive the solder wire fixing frame 8 towards the solder wire fixing column to ensure that the length of the suspended solder wire on the side of the solder wire fixing frame 8 close to the soldering pen 19 meets the requirements of the next welding; if the length of the solder wire between the solder wire fixing frame 8 and the solder wire straightening column 2 does not meet the requirements of the next welding, the worker can first turn the first threaded rod 102 to drive the solder wire fixing frame 8 towards the soldering pen 19. At this time, the clamping block 92 in the solder wire fixing frame 8 will drag out a new solder wire from the solder wire straightening column 2. When the length of the dragged-out solder wire is appropriate, turn the first threaded rod 102 to drive the solder wire fixing frame 8 close to the solder wire straightening column 2 to ensure that the suspended solder wire on the side of the solder wire fixing frame 8 close to the soldering pen 19 meets the requirements of the next welding. After adjusting the length of the solder wire, the solder liquid at the connection between the connector and the core wire cable just finishes cooling and solidifying. At this time, the welded connector and core wire cable are removed, and the next connector and core wire cable to be welded are replaced and the above operations are repeated.
