[0002] Lead welding refers to the welding between the coil head and the lead or the welding between the leads, and the welding quality has a great influence on product quality. The head needs to be arranged before lead welding. The paint film of the coil original wire at the lead connection is removed, and heating and chemical corrosion methods can be used. Before removing the paint film, the root of the head should be protected with cotton cloth to prevent damage to the root insulation during the work process. There are many lead welding methods, such as ultrasonic bonding, ball welding, etc.

[0003] At present, in the cable welding, the two ends of the cable are generally kept horizontal, and solder and welding iron are used. The welding iron melts the solder on the wire after heating, and the solder is enough to fill the gap between the metal conductor wires in the wire, so as to weld the wires together. Generally, multiple workers are needed to cooperate to complete the welding work, and the workers are prone to misalignment during the welding process, resulting in too thick welding points at the welding position, which does not meet the welding requirements and needs to be re-welded, affecting the use of the cable. The existing Chinese patent CN201920572419.2 discloses a welding device for cable core butt joint, which solves the problem of misalignment of the welding point in the prior art. However, when the welding end is bent, the problem of misalignment of the welding point still exists.

[0031] The transmission assembly comprises four tooth rods 6, each tooth rod 6 is engaged with a tooth ring 21, the tooth ring 21 is fixedly connected to the outside of the lower end of the transmission roller 4, the lower end of the tooth rod 6 is slidingly connected to the frame body 2, and the lower end of the tooth rod 6 is provided with a first spring 14 for resetting thereof; the end of the tooth rod 6 close to the welding assembly is slidingly connected with a support frame 16 for stabilizing the same, and the lower end of the support frame 16 is fixedly connected to the frame body 2; the outside of each tooth rod 6 is slidingly fixedly connected with a guide column 20, each guide column 20 is slidingly connected to a trapezoidal groove 19 opened in a support plate 13, and the support plate 13 is fixedly connected to the frame body 2.

[0032] Each tooth rod 6 is fixedly connected with a support rod 5, the upper end of the support rod 5 is fixedly connected with a wedge-shaped block 12, the side edge of the wedge-shaped block 12 is provided with a sliding clamping block 15, the clamping block 15 is slidingly connected with the frame body 2, and the clamping block 15 is provided with a second spring 17 for resetting thereof.

[0033] The welding assembly comprises two electric cylinders 7 symmetrically arranged relative to the frame body 2, the lower ends of the electric cylinders 7 are fixedly connected to the frame body 2, the output ends of the electric cylinders 7 are fixedly connected with a connecting plate 11, the middle part of the lower surface of the connecting plate 11 is fixedly connected with a liquid storage syringe 9, the liquid storage syringe 9 is provided with a third spring 10 for resetting, the middle part of the liquid storage syringe 9 is fixedly connected with a connecting frame 8, and the lower end of the connecting frame 8 is fixedly connected to the frame body 2.

[0034] The electric cylinder 7 is started to drive the connecting plate 11 to press downward, drive the upper end of the liquid storage syringe 9 to press downward, and make the tin liquid in the liquid storage syringe 9 drop on the connecting position between the two cables 18 to perform welding.

[0035] As a further scheme of the present application, the driving assembly comprises four first motors 3, each of which is fixedly connected to the frame body 2 and symmetrically arranged relative to the frame body 2.

[0036] In actual work process, the first motor 3 is started to drive the transmission roller 4 to rotate, the transmission roller 4 clamps and conveys the cable 18, at the same time, the driving gear ring 21 rotates in the transmission process of the transmission roller 4, the gear ring 21 drives the gear rod 6 to move, the gear rod 6 moves to the middle part of the frame body 2, the gear rod 6 drives the wedge-shaped block 12 to move through the support rod 5 at the same time, when the cable 18 moves to pass through the middle part of the clamping block 15 under the transmission of the transmission roller 4, the gear rod 6 drives the inclined surface of the wedge-shaped block 12 to drive the two clamping blocks 15 to move to the direction close to the cable 18, when the cable reaches the middle part of the frame body 2, the cable 18 is finally clamped and fixed, so that the two cables 18 are aligned (for example, the structure on the left side, and the structure on the right side moves in the same way), then the electric cylinder 7 is started to drive the connecting plate 11 to press downward, drive the upper end of the liquid storage syringe 9 to press downward, and make the tin liquid in the liquid storage syringe 9 drop on the connecting position between the two cables 18 to perform welding. Figure 1 This process does not need multiple workers to cooperate with welding, reduces the investment of worker cost, and also will not cause the misplacement of the two ends of the welded cable, the welding point to be too large or not meet the welding requirements.

[0037] The trapezoidal groove 19 of the embodiment is mainly used for conveniently moving the gear rod 6 and the wedge-shaped block 12 to the welding position, moving the gear rod 6 and the wedge-shaped block 12 in the trapezoidal groove 19 through the guide column 20, disengaging the gear rod 6 from the gear ring 21, and restoring to the initial position under the elastic force of the first spring 14 to realize the effect of automatic resetting.

[0038] The sliding clamping block 15 comprises an upper clamping block and a lower sliding block, the upper clamping block can move forward and backward on the lower sliding block, and the lower sliding block can move left and right on the frame body 2.

[0039] When the inclined surface of the wedge block 12 moves to contact the upper clamping block of the clamping block 15, the inclined surface of the wedge block 12 drives the upper clamping block of the clamping block 15 to move closer to the cable 18. Then, after the two upper clamping blocks clamp the cable 18, the straight edge of the wedge block 12 pushes the upper clamping block of the clamping block 15, thereby driving the sliding block of the clamping block 15 to move closer to the electric cylinder 7, moving the cable to the designated position.

[0040] Among them, the liquid storage pump tank 9 is an electric heating tank, which contains molten solder for spot welding. The electric heating tank is mainly used to keep the molten solder in a liquid state at all times.

[0041] The groove on the transmission roller 4 is adapted to the diameter of the cable 18.

[0042] The lower end of the liquid storage pump tank 9 is conical to facilitate the dripping of molten tin.

[0043] Working principle: First, the first motor 3 is started, driving the transmission roller 4 to rotate. The transmission roller 4 clamps and conveys the cable 18. At the same time, during the transmission process of the transmission roller 4, the toothed ring 21 is driven to rotate. The toothed ring 21 drives the toothed bar 6 to move. The toothed bar 6 moves towards the middle of the frame 2. While the toothed bar 6 is moving, it drives the wedge block 12 to move through the support rod 5. When the cable 18 moves under the transmission of the transmission roller 4 and passes through the middle of the clamping block 15, the toothed bar 6 drives the inclined surface of the wedge block 12 to drive the two clamping blocks 15 to move closer to the cable 18. When the cable reaches the middle of the frame 2, the cable 18 is finally clamped and fixed, aligning the two cables 18 (to...). Figure 1 Taking the structure on the left as an example (the movement of the structure on the right is the same), then the electric cylinder 7 is activated, causing the connecting plate 11 to press down, which in turn causes the upper end of the liquid reservoir 9 to press down, causing the molten solder in the liquid reservoir 9 to drip onto the connection between the two cables 18 for soldering. This process does not require multiple workers to cooperate in soldering, reducing the cost of labor. At the same time, it will not cause misalignment of the two ends of the soldered cables, excessively large solder joints, or situations that do not meet the soldering requirements. In addition, the two transmission rollers 4 can straighten the bent parts of the cables 18, which is convenient for use in actual use. If there are bent parts, workers do not need to manually straighten them with tools, which saves time and improves work efficiency.

[0044] The sliding clamp 15 comprises upper clamping blocks and lower sliding blocks. The upper clamping blocks can move forward and backward on the lower sliding blocks, and the lower sliding blocks can move left and right on the frame body 2. During operation, when the inclined surface of the wedge-shaped block 12 moves to contact the upper clamping blocks of the clamp 15, the inclined surface of the wedge-shaped block 12 drives the upper clamping blocks of the clamp 15 to move towards the side close to the cable 18. Then, when the two upper clamping blocks clamp the cable 18, the straight edge part of the wedge-shaped block 12 pushes the upper clamping blocks of the clamp 15, thereby driving the sliding blocks of the clamp 15 to move towards the side close to the electric cylinder 7, and moving the cable to the designated position.
