[0002] The mutual inductor, also known as instrument transformer, is a general term for current transformer and voltage transformer. It is a primary device that realizes the interconnection between the primary and secondary electrical systems. The mutual inductor converts the high voltage and large current of the primary system into low voltage and small current for use by measuring instruments, relay protection and automatic devices of the secondary system. When the mutual inductor is produced, the grounding copper busbar of its components needs to be welded, and thus a welding device is needed.

[0003] However, there are still some problems when using the existing welding device for processing the mutual inductor grounding copper bar: There is a copper busbar welding device with a Chinese patent application number of CN202223579216.7, which includes a base, a workbench is installed on the top outer wall of the base by bolts, and a top cover is welded on the top outer wall of the workbench, a screw rod is rotatably connected to the inside of the top cover by a bearing, and the outer thread of the screw rod is connected to a slide, a second electric telescopic rod distributed at an equal distance is installed on the bottom outer wall of the slide by bolts, and a lifting platform is installed on the output end of the second electric telescopic rod by bolts, a slider is arranged inside the lifting platform, and a cylinder is installed on the top outer wall of the slider by bolts, a lifting plate is installed on the output end of the cylinder by bolts, and a welding gun is installed on the bottom outer wall of the lifting plate by bolts; The existing copper bar welding equipment cannot perform continuous welding operations when in use. After the copper bar is welded, it is necessary to unload the material and reload the unwelded copper bar, which is cumbersome and has low welding efficiency. Most existing copper busbar welding devices require independent power sources or control structures for positioning the copper busbar and adjusting the position of the welding module. The design of multiple power sources inevitably increases the failure rate of the welding device.

[0004] In view of the above problems, an innovative design was carried out based on the original welding device for processing the transformer grounding copper bar. Summary of the invention

[0005] The purpose of the present invention is to provide a welding device for processing a mutual inductor grounding copper bar, so as to solve the problem in the above background technology that the existing copper bar welding equipment is unable to perform continuous welding operations due to cumbersome loading and unloading operations, which will inevitably affect the welding efficiency, and there is a risk of scalding during manual loading and unloading, and the safety is low.

[0006] To achieve the above object, the present invention provides the following technical solution: a welding device for processing a mutual inductor grounding copper bar, comprising a supporting platform: Positioning frames are fixed on the upper ends of both sides of the support platform, and the upper ends of the positioning frames are rotatably connected to transmission rods, the inner sides of the transmission rods are connected to transmission rollers, and the outer walls of the transmission rollers are provided with placement grooves; A support frame is fixed to the upper end of the rear side of the support platform, and an electric push rod is fixed to the upper end of the support frame, and the lower end of the electric push rod is fixedly connected to the movable frame, and a welding module is fixed to the lower end of the front side of the movable frame; A positioning seat is fixed to the upper end of the rear side of the support platform, and a movable plate is connected to the upper end of the positioning seat, and a welding pad is fixed to the upper side of the front end of the movable plate. A transmission rotating rod passes through the lower end of the support frame, and first pulleys pass through both ends of the transmission rotating rod. A transmission rack is fixed to the lower end of the rear side of the movable frame, and a transmission gear passes through the right side of the transmission rotating rod.

[0007] Preferably, two groups of transmission rods are provided, and the left transmission rod is higher than the right transmission rod, and the transmission rod is connected to the axis of the transmission roller; the placement groove array is distributed on the outer wall of the transmission roller.

[0008] By adopting the above technical solution, two sets of transmission rods and transmission rollers with different heights are designed to make the heights of the placement grooves different. When the placement grooves are placed on the grounding copper bars, the copper bars inside the two sets of placement grooves are stacked to facilitate quick welding.

[0009] Preferably, the electric push rods are symmetrically distributed on both sides of the support frame, and sliding guide rods are fixed on both sides of the support frame. The two groups of sliding guide rods respectively pass through the left and right ends of the movable frame, and the sliding guide rods are slidably connected to the movable frame. The welding module is externally covered with a protective cover, and the upper end of the protective cover is fixedly connected to the movable frame.

[0010] By adopting the above technical solution, the height of the movable frame can be adjusted through the design of the electric push rod, and the height of the welding module can be adjusted by the movable frame, thereby controlling the welding module and the welding pad to cooperate in welding the grounding copper busbar, and the design of the two sets of sliding guide rods can improve the lifting stability of the movable frame.

[0011] Preferably, a second pulley is fixed to the outer end of the two groups of transmission rods, and a transmission belt is connected between the second pulley and the first pulley, the transmission rotating rod is fixedly connected to the transmission gear, and the transmission gear is meshingly connected to the transmission rack.

[0012] By adopting the above technical scheme, through the cooperation of the second pulley, the first pulley and the transmission belt, the first pulley can be driven to rotate when the transmission rotating rod rotates in the forward direction, and the first pulley can use the transmission belt to drive the second pulley, the transmission rod and the transmission roller to rotate synchronously, so as to load and unload the grounding copper bar, and by using the cooperation of the transmission rack and the transmission gear, the transmission rack is driven to move synchronously when the movable frame moves downward, and the transmission rack is used to drive the transmission gear and the transmission rotating rod to rotate synchronously.

[0013] Preferably, an inner ratchet is fixed inside the first pulley, and a pawl is provided inside the inner ratchet, and the pawl is rotatably connected to the outer wall of the transmission rotating rod, the inner ratchet is meshed with the pawl, and a reset spring is fixed between the end of the pawl and the outer wall of the transmission rotating rod.

[0014] By adopting the above technical solution, through the cooperation of the inner ratchet and the pawl, the transmission rod can be controlled to provide unidirectional transmission power for the first pulley. When the transmission rod rotates forward, it can drive the first pulley to rotate synchronously, and when the transmission rod rotates reversely, the first pulley does not rotate, so as to avoid the rotation position deviation of the grounding copper busbar when the welding module moves downward for welding.

[0015] Preferably, the upper end of the positioning seat is slidably connected to the movable plate, and the upper end of the positioning seat is designed in a "T" shape. The upper end of the movable plate is connected to a second rack, a second gear is fixed in the middle of the transmission rod, and the lower end of the second gear is meshingly connected to the second rack.

[0016] By adopting the above technical scheme, the movable plate can be limited and installed through the positioning seat. When the transmission rod rotates, it can drive the second gear to rotate synchronously, and the transmission gear can be used to drive the second rack and the movable plate to move forward and backward. When the movable frame moves downward, it can drive the movable plate and the welding pad to move forward, so that the position of the welding pad corresponds to that of the welding module, which is convenient for welding the grounding copper busbar.

[0017] Preferably, a transmission plate is fixed to the upper end of the front side of the movable plate, and the transmission plate is designed in a "T" shape, and guide plates are fixed on both sides of the upper end of the transmission plate, the height of the guide plate on the left is lower than that of the guide plate on the right, and the opposite sides of the two groups of guide plates are designed in an inclined surface, and the two groups of guide plates correspond to the height of the placement grooves on the left and right sides.

[0018] By adopting the above technical solution, the two sets of guide plates are connected to the movable plate through a transmission plate, which can drive the guide plates to move synchronously when the movable plate moves forward, so that the guide plates push the copper bars inside the placement slots to move, and then limit the copper bars to ensure the accuracy of the welding position.

[0019] Preferably, a limiting plate is fixed to the upper end of the rear side of the support frame, and the limiting plate is designed in an "L"-shaped structure, and the adjacent ends of the two groups of limiting plates are designed in an arc shape.

[0020] By adopting the above technical solution, the design of the limit plate can prevent the copper bar inside the placement groove from being offset or detached when the transmission roller rotates, thereby improving the stability of the grounding copper bar during loading.

[0021] Preferably, a fixing frame is fixed in the middle of the rear side of the support platform, a positioning rod is fixed in the middle of the fixing frame, and a material discharge cam is fixed in the middle of the positioning rod. A material discharge trough is opened in the middle of the support platform, and a material discharge conveyor belt is installed inside the material discharge trough.

[0022] By adopting the above technical solution, the unloading cam is installed by means of a fixing frame and a positioning rod. The lower end of the unloading cam is designed to be convex. When the driving roller rotates, the grounding copper busbar inside the placement slot also rotates, and the unloading cam can push the grounding copper busbar out of the placement slot, thereby ensuring normal unloading. At the same time, because the unloading conveyor belt continuously rotates to connect the materials, the welded grounding copper busbar can be dispersed and spread on the surface of the unloading conveyor belt without accumulation, which accelerates the heat dissipation efficiency of the grounding copper busbar after welding, eliminates the need for manual unloading, and avoids the risk of scalding for staff.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: the welding device for processing the mutual inductor grounding copper busbar places the material through the rotation of the transmission roller, and directly rotates a certain angle after welding to carry out synchronous loading and unloading. The operation is simple and fast, and continuous welding operations can be carried out without manual control of loading and unloading, which saves time and improves the overall welding efficiency of the grounding copper busbar. The welding structure and the loading and unloading structure are linked to each other, which reduces the design of the power source and reduces the overall failure rate.

[0024] 1. By setting a one-way transmission structure, after the welding of the grounding copper bar is completed, the welding module is reset upward and the transmission structure is used to provide rotational power for the feeding structure. When the transmission roller rotates, the grounding copper bar after welding moves downward for unloading, and the grounding copper bar inside the upper placement slot is rotated to the front and placed horizontally, which is convenient for welding again, reducing the setting of the power source, improving the reliability of the welding device and reducing the failure rate; 2. By setting up an auxiliary unloading structure, the grounding copper bar after welding can be unloaded quickly and reliably to avoid the risk of burns caused by manual touch. By utilizing the design of the unloading cam, while the driving roller rotates to unload, the grounding copper bar after welding is constantly in contact with the unloading cam, and the lower end of the unloading cam is convex, which can squeeze the grounding copper bar out of the placement slot and fall onto the unloading conveyor belt below. It is dispersed and laid flat during transportation on the unloading conveyor belt without accumulation, which accelerates cooling. BRIEF DESCRIPTION OF THE DRAWINGS

In order to avoid the grounding copper bar being stuck in the placement groove 5, a unloading cam 29 is set, and its lower end is protruding. During the rotation of the transmission roller 4, the unloading cam 29 can continuously push the grounding copper bar out of the placement groove 5, so as to unload the material normally and improve the operation reliability.
