Description

Technical Field

[0001] The present invention relates to the technical field of automatic welding equipment, and particularly relates to an automatic welding equipment for copper strip coiling tubes. Background Art

[0002] Copper strips are mainly used in industries such as electronics, electrical, communication, network, mechanical hardware, construction, and household appliances. Copper strip coiling tubes are tubes welded from copper strips, with a thickness generally between 0.06 and 1.5 mm. Different materials of copper strips are selected, and their uses are also different.

[0003] When using an automatic welding equipment to weld copper strips into coiling tubes, the flat copper strip is placed at the fixed plate, and the copper strip is fixed by the clamps on both sides. Subsequently, the welding head passes through the contact points at both ends of the two copper strips for welding. During the welding process, the welding slag generated is likely to fall into the groove inside the fixed plate, resulting in the surface of the copper strip being indented when the subsequent copper strip is placed and in close contact with the inner wall of the groove of the fixed plate, and may cause the copper strip to deflect and shift at the inner wall of the fixed plate when the clamp clamps the copper strip, affecting the welding effect of the copper strip. Summary of the Invention

One side of the frame is provided with a third electric push rod, and the output rod of the third electric push rod slides on one side of the inner wall of the frame. The output rod of the third electric push rod is fixedly connected with a pushing plate, and the pushing plate slides on the outer surface of the positioning rod. One side of the top of the frame is provided with a hydraulic rod, and the output rod of the hydraulic rod is fixedly connected with a support rod. One side of the top of the support rod is provided with a servo motor, and the output end of the servo motor is fixedly connected with a lead screw. Both ends of the lead screw rotate at both ends of the inner wall of the support rod. A welding head is threadedly connected to the outer surface of the lead screw. The bottom end of the welding head is rotatably connected with a pressing wheel, and a welding gun is arranged at the bottom end of the welding head. A cleaning device is arranged on the outer surface of the frame. The cleaning device includes a sliding rod. One end of the sliding rod is fixedly connected with one side of the top of the pushing plate, and the outer surface of the sliding rod slides on one side of the inner wall of the frame. The end of the sliding rod far away from the pushing plate is fixedly connected with a ring, and a threaded ring is fixedly connected to the inner wall of the ring. One side of the frame is rotatably connected with a screw rod, and a long thread is provided on the outer surface of the screw rod. The inner wall of the threaded ring is threadedly connected with the outer surface of the screw rod. One end of the screw rod is fixedly connected with a plurality of fan blades, and a round hole is provided on one side of the frame, and the fan blades are located inside the round hole. One side of the bottom end of the pushing plate is rotatably connected with a shaft rod, and a rectangular rod is fixedly connected to the outer surface of the shaft rod. A plurality of soft brushes are fixedly connected to one side of the rectangular rod. One end of the shaft rod is provided with a coil spring, and both ends of the coil spring are respectively fixedly connected with one side of the shaft rod and one side of the pushing plate. The coil spring is in a compressed state.

[0006] The effects achieved by the above components are as follows: when the welding device is used to weld the copper strip coil, the copper strip is laid flat on the placement plate above the fixed block, and then the first electric push rod is operated to extend to control the fixed block to move upward so that the surface of the copper strip fits the outer surface of the positioning rod and the copper strip is bent, and then the two second electric push rods are operated to extend to control the two clamping plates to move closer to the middle to push the two ends of the bent copper strip to fit the outer surface of the positioning rod so that the copper strip is bent into a coil, and then the hydraulic rod is operated to contract to control the frame rod to descend so that the pressure wheel at the bottom of the welding head presses Above both ends of the copper strip, the servo motor on one side of the rack rod is operated to drive the screw rod to rotate, so that the welding head moves on the outer surface of the screw rod, and the pressure wheel at the bottom of the welding head moves on the surface of both ends of the copper strip to flatten the copper strip, and the two ends of the copper strip are welded by the welding gun, so that the copper strip is rolled into a tube and sleeved on the outer surface of the positioning rod. After the welding is completed, the hydraulic rod is extended to make the rack rod rise, and the servo motor is operated to drive the screw rod to rotate to return the welding head to its original position, and then the two second electric push rods are operated to shrink and drive the splint to move away from the positioning rod, and the first electric push rods are operated The rod contracts to make the fixed block drop, and finally the third electric push rod is operated to control the push plate to slide on the outer surface of the positioning rod to push the coiled tube sleeved on the outer surface of the positioning rod away from the surface of the positioning rod to take out the coiled tube. When the push plate moves outward, it will drive the sliding rod to slide on the inner wall of the frame toward the direction of the positioning rod. At the same time, the threaded ring on the inner wall of the circular ring at one end of the sliding rod will move on the outer surface of the screw to drive the screw and the fan blades to rotate. The welding slag in the groove on the outer surface of the fixed block is blown away from the surface of the fixed block through the rotating fan blades. At the same time, the push plate moves outward to move the rectangular rod to above the fixed block. When the push plate moves, the coil spring at one end of the shaft rod returns to its original state, which will drive the shaft rod to rotate downward, making the rectangular rod and the placement plate perpendicular to each other, so that the soft brush on one side of the rectangular rod can sweep and clean the inside of the groove on the outer surface of the fixed block, and further clean the welding slag on the surface of the fixed block to avoid welding slag from remaining on the outer surface of the fixed block as much as possible. When the third electric push rod contracts and drives the push plate back to its original position, the bottom end of the rectangular rod contacts the outer surface of the placement plate, which will push the shaft rod and the rectangular rod to rotate upward and compress the coil spring, so that one side of the rectangular rod fits against the outer surface of the placement plate.

[0007] Preferably, the outer surface of the soft brush is in an arc shape, and the length of the soft brushes at both ends of the rectangular rod is smaller than the length of the soft brush at the middle end of the rectangular rod.

[0009] Preferably, one end of the sliding rod away from the push plate is fixedly connected to a limiting rod, and one side of the limiting rod slides on one side of the top end of the frame.

[0010] The effect achieved by the above components is that when the push plate moves and drives the sliding rod to move, one side of the limit rod will slide on one side of the frame. The limit rod can further limit the angle between the sliding rod and the frame, thereby avoiding the angle of the sliding rod from being deflected when moving as much as possible.

[0011] Preferably, a filter plate is fixedly connected to the inner wall of the circular hole, and a filter screen is arranged on the outer surface of the filter plate.

[0012] The effect achieved by the above components is: when the fan blades rotate and blow the air, it will pass through the filter plate. The filter outside the filter plate can filter the dust and impurities in the air, and block the impurities on the side of the filter plate close to the fan blades as much as possible, so that the impurities will not follow the air into the surface of the fixed block.

[0013] Preferably, a collecting device is provided on one side of the placement plate, and the collecting device includes a trough box, two plug-in blocks are fixedly connected to one end of the trough box, a falling groove is provided inside the trough box, a card slot is provided on one side of the inner wall of the trough box, a sliding plate is slidably connected to the inner wall of the trough box, and two slots are provided at one end of the placement plate, and the size and shape of the outer surface of the plug-in block are adapted to the size and shape of the inner wall of the slot.

[0014] The effect achieved by the above components is: when using the automatic welding device, the two plugs at one end of the slot box can be inserted into the two slots at one end of the placement plate, and the slot box can be installed at one end of the placement plate. The welding slag cleaned by the cleaning device will enter the interior of the slot box for collection. After the welding equipment is used, the slot box can be pulled to pull the two plugs at one end of the slot box out of the slots to remove the slot box, and then the sliding plate can be pulled to open the drop slot inside the slot box to clean the welding slag collected inside the slot box. After cleaning, the sliding plate can be pushed to move and insert one end into the card slot to close the drop slot, thereby improving the practicality and convenience when using the cleaning device.

[0015] Preferably, one end of the trough box is fixedly connected to a pull rod, and the cross-sectional shape of the pull rod is U-shaped.

[0016] The effect achieved by the above components is that by holding the outer surface of the U-shaped pull rod, the pull rod can be pulled more conveniently to control the slot box, thereby facilitating the disassembly and assembly of the slot box.

[0017] Preferably, a plurality of convex strips are fixedly connected to the outer surface of the plug-in block, the convex strips are linearly distributed on the outer surface of the plug-in block, and the convex strips are rubber strips made of rubber material.

[0018] The effect achieved by the above components is that the friction between the plug-in block and the inner wall of the slot when the plug-in block is inserted into the slot can be increased by providing the convex strips made of rubber material, so that the plug-in block is not easy to accidentally fall off from the inside of the slot.

[0019] Preferably, one end of the sliding plate is fixedly connected with a groove block, and a groove is opened at the bottom end of the groove block.

[0020] The effect achieved by the above components is that it is more convenient to pull the groove block by hooking the hand at the groove at the bottom end of the groove block to control the movement of the sliding plate and open the falling groove.

[0021] Compared with the prior art, the advantages and positive effects of the present invention are as follows: In the present invention, by setting up a cleaning device, when the third electric push rod is operated to control the push plate to move on the outer surface of the positioning rod and push out the coiling tube, the screw ring at one end of the sliding rod can drive the screw rod and the fan blade to rotate, so that the fan blade generates wind power to blow away the welding slag on the outer surface of the fixed block. At the same time, the soft brush on one side of the rectangular rod will move on the outer surface of the fixed block, and the outer surface of the fixed block can be further cleaned by the soft brush, as much as possible to avoid the welding slag remaining on the outer surface of the fixed block, which affects the subsequent fixing of the position of the copper strip on the outer surface of the fixed block and the welding effect.

Both ends of the coil spring 210 are respectively fixedly connected with one side of the shaft rod 27 and one side of the pushing plate 11. The coil spring 210 is in a compressed state. When using the welding device to weld the copper strip coiling pipes, the copper strip is laid flat on the placing plate 4 above the fixing block 6. Subsequently, the first electric push rod 5 is operated to extend to control the fixing block 6 to move upward, so that the surface of the copper strip is attached to the outer surface of the positioning rod 7 and the copper strip is bent. Then, the two second electric push rods 8 are operated to extend to control the two clamping plates 9 to move closer to the middle, pushing the two ends of the bent copper strip to be attached to the outer surface of the positioning rod 7 to bend the copper strip into a coiling pipe. Then, the hydraulic rod 12 is operated to contract to control the support rod 13 to descend, so that the pressing wheel at the bottom end of the welding head 16 presses on the upper sides of the two ends of the copper strip. And the servo motor 14 on one side of the support rod 13 is operated to drive the lead screw 15 to rotate, so that the welding head 16 moves on the outer surface of the lead screw 15.

After the welding is completed, the hydraulic rod 12 is extended to make the frame rod 13 rise, and the servo motor 14 is operated to drive the screw rod 15 to rotate to return the welding head 16 to its original position, and then the two second electric push rods 8 are operated to shrink and drive the clamping plate 9 to move away from the positioning rod 7, and the first electric push rod 5 is operated to shrink and the fixed block 6 is lowered. Finally, the third electric push rod 10 is operated to control the push plate 11 to slide on the outer surface of the positioning rod 7 to sleeve When the reel on the outer surface of the positioning rod 7 is pushed away from the surface of the positioning rod 7 to take out the reel, when the push plate 11 moves outward, it will drive the sliding rod 21 to slide on the inner wall side of the frame 1 in the direction of the positioning rod 7, and at the same time, the threaded ring 23 on the inner wall of the circular ring 22 at one end of the sliding rod 21 will move on the outer surface of the screw 24, driving the screw 24 and the fan blade 26 to rotate, and the welding slag in the groove on the outer surface of the fixed block 6 will be blown off the surface of the fixed block 6 by the rotating fan blade 26.
