Description

Technical Field

[0001] The present invention relates to the technical field of cable welding machines, in particular to a multi-head cable welding machine. Background Art

[0002] A wire welding machine is an automated or semi-automatic device used to weld wires (such as wires, cables, and conductors) to each other or to other electronic components (such as terminals, connectors, and splices). Using a specific welding process, it permanently connects the conductors (typically metals like copper and aluminum) of a wire, ensuring good electrical conductivity, mechanical strength, and stability.

[0003] A multi-head cable welding machine is a welding machine with multiple welding ends, which is used to handle cable welding operations. During the welding operation of the existing multi-head welding machine, it is necessary to pre-align the positions of multiple cables to ensure that there will be no position deviation in the subsequent welding operation. However, during this welding operation, the preliminary preparations for cable welding require a lot of time, and in the actual welding process, the thicker cables cannot be rotated and adjusted by themselves, resulting in poor welding effects. Manual rotation of the cable welding points is required, which slows down the welding efficiency. Summary of the Invention

[0004] In order to save the time consumed in manually adjusting the cable alignment and thus improve the cable welding efficiency, the present invention adopts the following technical solutions: A multi-head cable welding machine includes a base and a second connecting plate. Both ends of the base are provided with a stabilizing frame. The inner ring surface of the stabilizing frame is provided with a balancing groove and an embedded groove. A rotating frame is rotatably provided on the stabilizing frame. The outer ring of the rotating frame is provided with a balancing arc plate that rotatably fits with the balancing groove. Both ends of the second connecting plate are provided with a connecting mechanism. The rotating frame is provided with a limit plate. The rotating frame is provided with a mounting groove, and the outer surface of the rotating frame is provided with a rotating groove located outside the mounting groove. A spur gear is rotatably arranged in the rotating groove, and the spur gear is rotatably fitted with the rotating groove through a connecting ring. The spur gear is provided with a wire clamping mechanism for clamping the cable end, and the wire clamping mechanism includes a first clamping plate fixedly connected to the outer surface of the spur gear.

[0005] Preferably, a second clamping plate is slidably mounted on the outer surface of the spur gear, a sliding groove is provided on the outer surface of the spur gear, and a slider is slidably mounted on the inner side of the second clamping plate.

[0006] Preferably, both ends of the first splint and the second splint are provided with spring cylinders, a connecting rod is movably sleeved inside the spring cylinder, and both ends of the connecting rod are provided with return springs whose ends are connected to the inner cavity of the spring cylinder.

[0007] Preferably, a rotation-stop plate is provided on the outer surface of the first clamping plate, and a pad is provided on the inner annular surface of the second clamping plate.

[0008] Preferably, the connecting mechanism is rotatably fitted to the rotating frame, a first connecting plate is provided on the inner surface of the rotating frame, and a welder for cable welding is provided on the first connecting plate.

[0009] Preferably, an inner gear ring is provided on the inner surface of the rotating frame, and the connecting mechanism includes a rotating ring rotatably fitted with the rotating frame, and an external suspension is provided on the outer surface of the rotating ring.

[0010] Preferably, a first ring frame is provided on the rotating ring, a bottom end of the first ring frame is provided with teeth that mesh with the spur gear, and a second ring frame is further provided on the first ring frame.

[0011] Preferably, the first clamping plate is provided with a rotation-stop plate that matches the sliding limit of the second ring frame, the outer side of the stabilizing frame is provided with an extrusion arc plate for squeezing the second clamping plate close to the first clamping plate, and the top of the stabilizing frame is provided with a wire blocking plate for controlling the cable welding point.

[0012] Preferably, a transmission shaft is rotatably provided at the bottom of the second connecting plate, and transmission gears meshing with the inner gear ring are provided at both ends of the transmission shaft.

[0013] Preferably, a driving motor is provided on the top surface of the second connecting plate, a driving bevel gear is provided at the bottom end of the output shaft of the driving motor, and a driven bevel gear meshing with the driving bevel gear is provided in the middle section of the transmission shaft.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up the rotating frame and utilizing the mutual cooperation between the spur gear and the wire clamping mechanism, the two cables can be loaded, welded and unloaded in a streamlined operation. Moreover, according to the meshing matching between the spur gear and the teeth, the two cables can be rotated 360 degrees during the welding operation of the welding machine, thereby improving the welding effect between the two cables and eliminating the need for manual adjustment of the welding position, effectively improving the welding efficiency of the cables.

[0015] 2. Through the setting of the stabilizing frame and the connecting mechanism, and by utilizing the cooperation between the anti-rotation plate and the second ring frame, as well as the cooperation between the second clamping plate and the extrusion arc plate, the second clamping plate can be adjusted in displacement according to the position of the spur gear relative to the stabilizing frame, so as to facilitate its cooperation with the first clamping plate to clamp and release the cable, thereby facilitating the cable clamping operation.

[0016] 3. By setting up the wire baffle and utilizing the synchronous rotation between the two rotating frames, the distance between the two cables can be adjusted when the two cables are inserted and clamped to meet different subsequent welding requirements. In addition, the two cables will be automatically aligned before welding to avoid the occurrence of subsequent welding point offset.

[0017] In summary, the present invention overcomes the shortcomings of the existing technology. Through the setting of the rotating frame, the two cables can be loaded, welded and unloaded in an assembly line operation, and the cables can be welded 360 degrees during welding, which improves the efficiency of the welding process and has high social use value and application prospects.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0029] Example 1 Reference Figures 1 to 8 A multi-head cable welding machine includes a base 1 and a second connecting plate 4. Both ends of the base 1 are provided with a stabilizing frame 2. The inner ring surface of the stabilizing frame 2 is provided with a balancing groove 201 and an embedded groove 202. A rotating frame 3 is rotatably provided on the stabilizing frame 2. The outer ring of the rotating frame 3 is provided with a balancing arc plate 31 that rotates with the balancing groove 201. Both ends of the second connecting plate 4 are provided with a connecting mechanism 42. A limit plate 5 is provided on the rotating frame 3. The rotating frame 3 is provided with a mounting groove 32, and the outer surface of the rotating frame 3 is provided with a rotating groove 35 located outside the mounting groove 32. A spur gear 6 is rotatably provided in the rotating groove 35. The spur gear 6 is rotatably fitted with the rotating groove 35 through a connecting ring 61. The spur gear 6 is provided with a clamping mechanism 7 for clamping the cable end. The clamping mechanism 7 includes a first clamping plate 701 fixedly connected to the outer surface of the spur gear 6. Figure 1 As shown, the welding machine rotates clockwise, which is used to perform the process operations of cable loading and clamping, rotation welding and unloading and loosening.

[0030] Specifically, refer to Figure 7 and Figure 8The outer surface of the spur gear 6 is slidably fitted with a second clamping plate 702, and a slide groove 601 is provided on the outer surface of the spur gear 6. The inner side of the second clamping plate 702 is provided with a slider 7021 that is slidably fitted with the slide groove 601. The second clamping plate 702 can slide on the surface of the spur gear 6 under the sliding cooperation between the slider 7021 and the slide groove 601, so that the second clamping plate 702 is close to and away from the first clamping plate 701 to complete the clamping and releasing operations of the cable.

[0031] Specifically, refer to Figure 7 and Figure 8 Both ends of the first splint 701 and the second splint 702 are provided with spring tubes 705, and a connecting rod 706 is movably sleeved inside the spring tube 705. Both ends of the connecting rod 706 are provided with return springs 707 whose ends are connected to the inner cavity of the spring tube 705. When the second splint 702 moves closer to the first splint 701, the return spring 707 will be compressed and elastically deformed as the second splint 702 moves away from the first splint 701, and the return spring 707 will restore its elastic deformation accordingly.

[0032] Specifically, refer to Figure 7 and Figure 8 A stop plate 703 is provided on the outer surface of the first clamping plate 701 , and a pad 704 is provided on the inner ring surface of the second clamping plate 702 .

[0033] Example 2 Reference Figures 1 to 8 The difference between this embodiment and the first embodiment is that the connecting mechanism 42 is rotatably fitted to the rotating frame 3, a first connecting plate 34 is provided on the inner surface of the rotating frame 3, and a welder 302 for cable welding is provided on the first connecting plate 34. The two ends of the first connecting plate 34 are respectively connected to the rotating frame 3. There are three first connecting plates 34, and there are three welders 302. The welder 302 is only turned on when the spur gear 6 is meshed with the teeth 4203. When the meshing and matching between the spur gear 6 and the teeth 4203 are completed, the welder 302 stops working.

[0034] Specifically, refer to Figure 6 An inner gear ring 33 is provided on the inner surface of the rotating frame 3, and the connecting mechanism 42 includes a rotating ring 4201 that is rotatably mounted on the rotating frame 3. An external suspension 421 is provided on the outer surface of the rotating ring 4201. The external suspension 421 is used to connect to an external supporting structure. When the device is running, the connecting mechanism 42 as a whole is always in a stationary state relative to the external supporting structure.

[0035] Specifically, refer to Figures 4 to 6A first ring frame 4202 is provided on the rotating ring 4201, and a tooth 4203 is provided at the bottom end of the first ring frame 4202 to engage with the spur gear 6. A second ring frame 4204 is also provided on the first ring frame 4202. Through the setting of the second ring frame 4204, when the spur gear 6 drives the first clamping plate 701 to rotate, the outer arc surface of the anti-rotation plate 703 will contact the outer arc surface of the second ring frame 4204, thereby stopping the first clamping plate 701 from rotating, preventing the second clamping plate 702 from being unable to approach the first clamping plate 701 under the extrusion limiting action of the extrusion arc plate 203 during the subsequent clamping process.

[0036] Specifically, refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 7 and Figure 8 The first clamping plate 701 is provided with a stop plate 703 that matches the sliding limit of the second ring frame 4204, and the outer side of the stabilizing frame 2 is provided with an extrusion arc plate 203 for squeezing the second clamping plate 702 close to the first clamping plate 701. The top of the stabilizing frame 2 is provided with a wire baffle 21 for controlling the welding point of the cable. The thickness of the wire baffle 21 can be adjusted according to the actual welding processing situation. When the required welding spacing between the two cables is large, the thickness of the wire baffle 21 can be increased to control the distance between the two cables, and vice versa. The setting of the wire baffle 21 can help the two cables to align the two cables after being inserted into the spur gear 6, so that the welding point between the two is aligned with the output end of the welding machine 302, avoiding the problem of deviation in the welding position affecting the welding effect.

[0037] Specifically, refer to Figure 3 and Figure 6 A transmission shaft 43 is rotatably provided at the bottom of the second connecting plate 4 , and both ends of the transmission shaft 43 are provided with transmission gears 432 that mesh with the inner gear ring 33 .

[0038] Specifically, refer to Figures 1 to 3 and Figure 6 A driving motor 41 is provided on the top surface of the second connecting plate 4, and a driving bevel gear 411 is provided at the bottom end of the output shaft of the driving motor 41. A driven bevel gear 431 meshing with the driving bevel gear 411 is provided in the middle section of the transmission shaft 43. Through the arrangement of the transmission shaft 43, the output shaft of the driving motor 41 drives the driving bevel gear 411 to rotate, thereby utilizing the meshing and matching effect to drive the driven bevel gear 431 to rotate, so as to allow the transmission gear 432 to drive the inner gear ring 33 to rotate, so that the two rotating frames 3 can rotate at the same speed and in the same direction.

[0039] For other structures not described, refer to Example 1.

[0040] Working principle: In the present invention, the two cables to be welded are inserted into the oppositely arranged spur gears 6, and then according to the rotation of the rotating frame 3, the ends of the two cables are respectively contacted with the two side surfaces of the wire baffle 21, and as the rotating frame 3 continues to rotate, the spur gear 6 enters the embedded groove 202. At this time, the anti-rotation plate 703 and the second ring frame 4204 are in a sliding contact state, so that the spur gear 6 cannot rotate, and the second clamping plate 702 will be limited by the extrusion arc plate 203, so that the second clamping plate 702 is close to the first clamping plate 701, and the reset spring 707 will produce elastic deformation, so that the two end points of the first clamping plate 701 and the second clamping plate 702 are in contact, so that the cables are clamped under the action of the first clamping plate 701 and the second clamping plate 702, so that the distance between the two cables is fixed; When the spur gear 6 begins to mesh with the teeth 4203, the contact state between the anti-rotation plate 703 and the first ring frame 4202 is released. As the rotating frame 3 rotates, the spur gear 6 can rotate, and the welder 302 is simultaneously turned on at this time to weld the ends of the two cables. The rotation of the spur gear 6 and the clamping effect of the wire clamping mechanism 7 on the cables allow the cables to rotate by themselves, thereby allowing the welder 302 to perform a 360-degree welding process on the cables. When the cable diameter is large, the welding effect of the cable can be improved, and there is no need to manually adjust the welding position of the cable. When the wire clamping mechanism 7 drives the cable to rotate, the limit plate 5 can limit the relative position between the first clamping plate 701 and the second clamping plate 702 to prevent the relative position change between the first clamping plate 701 and the second clamping plate 702 from affecting its clamping of the cable. When the cable is welded, the cable also completes a 360-degree rotation. Then the spur gear 6 will rotate out from the other end of the embedded groove 202, and the synchronous anti-rotation plate 703 will make limited sliding contact with the first ring frame 4202, so that the spur gear 6 will no longer rotate. At the same time, the second clamping plate 702 will be restored under the constraint and push of the extrusion arc plate 203, so that the elastic deformation of the reset spring 707 will be restored, so that the second clamping plate 702 and the first clamping plate 701 will release the clamping of the cable, and then the welded cable will be pulled out, and the clamping operation of the next group of cables can be carried out.

[0041] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by a person skilled in the art. The provision of power is also common knowledge in the art. The present invention is mainly used to protect mechanical devices, so the control method and circuit connection are not explained in detail in the present invention.

[0042] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
