Description

Technical Field

[0001] This invention relates to the field of current transformer processing technology, and in particular to a current transformer assembly and processing apparatus. Background Technology

[0002] After winding, coil components require soldering the coil leads to the terminals. The coil is then assembled into a housing and encapsulated with potting compound to obtain a complete electrical component. In existing technologies, coil soldering and assembly typically employ a manual, automated assembly line approach. However, these existing devices and methods have several shortcomings. For example, manual operation is inefficient, and automated operations lack effective multi-dimensional constraint mechanisms because the cut wires are irregularly twisted, bent, or fluffy.

[0003] Therefore, it is necessary to provide a current transformer assembly and processing device to achieve multi-dimensional reliable constraint of wires, stable feeding and accurate positioning of terminals, and accurate reset of flip-over components, thereby improving welding quality and assembly accuracy. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention discloses a device capable of reliably constraining wires in multiple dimensions, achieving stable feeding and accurate positioning of terminals, and ensuring precise resetting of flip-over components, thereby improving welding and assembly. The technical solution adopted by this invention is as follows: a current transformer assembly and processing device, including a conveying mechanism and a feeding mechanism mounted on the conveying mechanism. The feeding mechanism cooperates with a welding mechanism. The welding mechanism includes a bracket, on which a U-shaped plate is rotatably mounted. Normally, the U-shaped plate is placed horizontally. A long slide is slidably mounted on the bracket, and two positioning slide rods are slidably mounted on the long slide, either opposite or facing away from each other. A positioning pressure plate is fixedly installed at the first end of the positioning slide rod, and a sliding pressure plate is slidably installed at the second end of the positioning slide rod. An arc-shaped retaining strip is provided at the bottom of the positioning pressure plate, and an arc-shaped protruding end is provided at the top of the sliding pressure plate. The sliding pressure plate cooperates with the bracket and the trapezoidal plate. The trapezoidal plate is fixedly installed on the bracket. The protruding width of the protruding end on the sliding pressure plate and the width of the retaining strip are both smaller than the diameter of the wire on the coil. A positioning rack is fixedly installed on each positioning slide rod. Both positioning racks mesh with gear three. Gear three rotates around the axis and is installed on the connecting slider. The connecting slider is fixedly installed on the long slide.

[0005] Furthermore, gear three is coaxially and fixedly connected to gear one, gear one meshes with gear two, gear two cooperates with fixed rack, and fixed rack is fixedly installed on bracket, with the fixed rack corresponding to the position of trapezoidal plate.

[0006] Furthermore, a limit frame is installed on gear two. The limit frame cooperates with a spring plate, which has elasticity and is fixedly installed on the connecting slider.

[0007] Furthermore, the support is equipped with two limiting seats, which correspond to the positions of the unloading slides. There are two unloading slides, which are fixedly installed on the support. The unloading slides are equipped with inclined sections, and the two unloading slides are symmetrically distributed on both sides of the lifting and moving frame.

[0008] Furthermore, a mating plate is fixedly installed on the lifting and moving frame. The mating plate is provided with a U-shaped bayonet. The mating plate mates with the rotating disk and the position corresponds to the rotating disk. The rotating disk mates with the spatial cylinder. The spatial cylinder is fixedly connected to the gears on the same axis. A sliding column is provided on the rotating disk and slides in the threaded groove of the spatial cylinder. Under normal conditions, the rotating disk naturally slides to the bottom of the spatial cylinder.

[0009] Furthermore, the support, the feeding slide, and the limit seat are provided with coaxially arranged holes that are consistent with the maximum diameter of the wiring terminal. Two push rods are symmetrically installed on the lifting and moving frame. The push rods are the same as the maximum diameter of the wiring terminal and the push rods are positioned corresponding to the limit seat. A welding hydraulic cylinder is installed on the lifting and moving frame and is connected to the support.

[0010] Furthermore, a welding torch is installed on the bracket, and the welding torch is positioned corresponding to the limit seat.

[0011] Furthermore, the U-shaped plate is connected to the bracket by a torsion spring, and a limiting side plate is provided on each side of the U-shaped plate.

[0012] Furthermore, a rotating frame is rotatably mounted on the support, and a feeding slide is slidably mounted on the rotating frame. A two-way hydraulic cylinder is mounted on the feeding slide, and two clamping plates are mounted on the piston rod of the two-way hydraulic cylinder. Each clamping plate is provided with a friction plate, and the two clamping plates move relative to or away from each other.

[0013] Furthermore, a synchronous belt assembly is provided below the rotating frame, and a base frame is installed on the synchronous belt assembly. The base frame operates intermittently, and each operation of the base frame drives the housing to move a preset distance. The conveying mechanism also includes a robot arm, which is positioned corresponding to the U-shaped plate.

[0014] The beneficial effects of this invention compared with the prior art are: (1) By setting up a cooperative structure of positioning pressure plate, sliding pressure plate, trapezoidal plate and clamping strip, the positioning pressure plate and sliding pressure plate gradually approach each other in the horizontal direction during the movement of the long carriage, clamping the wire laterally; then the sliding pressure plate slides down along the inclined section of the trapezoidal plate, and its protruding end presses the wire longitudinally onto the clamping strip. Through the dual constraint mechanism of first horizontal and then vertical, the wire that is irregularly twisted after being cut is simultaneously constrained in two dimensions during the conveying process, effectively solving the problem of wire displacement and torsion caused by relying only on unidirectional pressure plate in the prior art. (2) The present invention drives the coil to rotate 180 degrees by driving the rotating frame. During this process, the U-shaped plate rotates to make way. After the rotation is completed, the U-shaped plate is reset under the action of the torsion spring. At the same time, the base frame moves stepwise to achieve precise positioning of the shell, so that the coil can be accurately inserted into the shell. (3) The present invention integrates the wire constraint, terminal welding, coil rotation, shell assembly and glue injection processes into the same device. Through the coordinated action of the welding screw, welding hydraulic cylinder, feeding motor, lifting motor and base frame, the entire process of coil from winding to finished product assembly and glue injection is fully automated.

A U-shaped plate 208 is rotatably mounted. Under normal conditions, the U-shaped plate 208 is placed horizontally. A long slide 303 is slidably mounted on the bracket 301.

A positioning pressure plate 317 is fixedly mounted at the first end of each positioning slide rod 313, and a sliding pressure plate 315 is slidably mounted at the second end of each positioning slide rod 313. An arc-shaped retaining strip 316 is provided at the bottom of the positioning pressure plate 317, and an arc-shaped protruding end is provided at the top of the sliding pressure plate 315. The sliding pressure plate 315 cooperates with the bracket 301 and the trapezoidal plate 302, which is fixedly mounted on the bracket.

[0028] A limit frame 311 is installed on gear 2 309. The limit frame 311 cooperates with the spring plate 307, and the spring plate 307 is fixedly installed on the connecting slider 306.

[0029] like Figures 5-9 The bracket 301 is provided with two limiting seats 321, which correspond to the positions of the unloading slide 320. There are two unloading slides 320, which are fixedly installed on the bracket 301. The two unloading slides 320 are provided with inclined sections, and the unloading slides 320 are symmetrically distributed on both sides of the lifting and moving frame 318.

[0030] like Figures 5-9 The bracket 301, the unloading slide 320, and the limit seat 321 are provided with holes that are coaxially arranged with the same maximum diameter as the terminal block 322. Two push rods 319 are symmetrically installed on the lifting and moving frame 318. The push rods 319 have the same maximum diameter as the terminal block 322 and the push rods 319 correspond to the position of the limit seat 321. A welding hydraulic cylinder 324 is installed on the lifting and moving frame 318 and is connected to the bracket 301.

[0031] A welding torch 323 is mounted on the bracket 301, and the welding torch 323 corresponds to the position of the limit seat 321.

[0032] like Figures 3-4 The U-shaped plate 208 is connected to the bracket 301 via a torsion spring 210, and a limiting side plate 209 is provided on each side of the U-shaped plate 208.

[0033] like Figures 2-4 A rotating frame 202 is rotatably mounted on the bracket 301. The rotating frame 202 is connected to the feeding motor 201, which is mounted on the bracket 301. A feeding slide 204 is slidably mounted on the rotating frame 202. The feeding slide 204 is threadedly connected to the feeding screw 211, which is rotatably mounted on the rotating frame 202. The feeding screw 211 is connected to the lifting motor 203, which is mounted on the rotating frame 202. A two-way hydraulic cylinder 205 is mounted on the feeding slide 204. Clamping plates 206 are installed at the two piston rods of the two-way hydraulic cylinder 205. Each clamping plate 206 is provided with a friction plate 207. The two clamping plates 206 can move relative to or away from each other.

[0034] like Figures 1-4A timing belt assembly 102 is provided below the rotating frame 202. A base frame 101 is installed on the timing belt assembly 102. Multiple housings 105 are placed on the base frame 101. The base frame 101 operates intermittently. Each operation of the base frame 101 causes the housings 105 to move a preset distance. A glue injection assembly 103 is installed on the timing belt assembly 102. The glue injection assembly 103 is used to inject glue into the housings 105 of the assembled coils 106. The robot arm 104 is positioned corresponding to the U-shaped plate 208. The robot arm 104 is used to pick up the coils 106 that have been wound by the winding machine and place them onto the U-shaped plate 208.

[0035] The working principle of this invention is as follows: After the winding machine cuts the wire of the wound coil 106, it is picked up by the robot arm 104 and placed on the U-shaped plate 208. At this time, the U-shaped plate 208 is placed horizontally, and the limiting side plates 209 on both sides of the U-shaped plate 208 limit the coil 106. At the same time, the bidirectional hydraulic cylinder 205 is activated to extend the piston rod so that the clamping plate 206 and the friction plate 207 move backward and clamp the inner coil of the coil 106 to position the coil 106. At this time, the twisted wire on the coil 106 falls in a messy state above the long slide 303. In the initial state, the two positioning pressure plates 317 are respectively located on both sides of the gear 312.

[0036] The welding motor 305 is started, which drives the welding screw 304 to rotate, causing the long slide 303 to slide on the bracket 301. The long slide 303 drives the connecting slider 306, the positioning slide rod 313, and the positioning rack 314 to move, which in turn drives the second gear 309 to move. The second gear 309 meshes with the fixed rack 310 and rotates, which drives the first gear 308 to rotate. The first gear 308 drives the third gear 312 to rotate. The third gear 312 drives the positioning rack 314 and the positioning slide rod 313 to move relative to each other, which causes the sliding pressure plate 315 on one set of positioning slide rods 313 to gradually approach the positioning pressure plate 317 on another set of positioning slide rods 313, pushing the wire that falls on the long slide 303.

[0037] The bottom end of the sliding pressure plate 315 is initially in contact with the trapezoidal plate 302. During the movement of the long slide 303, the sliding pressure plate 315 slides onto the inclined section of the trapezoidal plate 302, and then slides onto the bracket 301. During this process, the sliding pressure plate 315 slides relative to the positioning slide rod 313. As the sliding pressure plate 315 slides down, it approaches the positioning pressure plate 317 on another set of positioning slide rods 313 until the protruding end of the sliding pressure plate 315 presses the wire onto the retaining strip 316, thus restricting the irregular shape of the wire in both the horizontal and vertical directions.

[0038] When gear 2 309 rotates, it drives the limiting frame 311 to rotate. The rotation of the limiting frame 311 pushes the spring plates 307 on both sides, and the spring plates 307 bend adaptively. When gear 2 309 disengages from the fixed rack 310, the position of the limiting frame 311 is limited by the elastic force of the spring plates 307, thereby limiting gear 2 309, gear 1 308, and gear 3 312, so that the wire is kept in a clamped state.

[0039] The long slide 303 moves a preset distance, causing the straightened wire to appear at the corresponding position on the limit seat 321. At this time, the rotating disk 326 moves into the U-shaped bayonet of the mating plate 325. Then, the welding torch 323 automatically welds the wire on the coil 106 to the terminal 322 in the limit seat 321. After welding, the welding hydraulic cylinder 324 is activated to drive the lifting moving frame 318 to slide upward, completely pushing the welded terminal 322 out of the limit seat 321. At the same time, the mating plate 325 pushes the rotating disk 326 upward. As the rotating disk 326 slides on the spatial cylinder 327, it drives the spatial cylinder 327 to rotate, which in turn drives the gear 312 to rotate, so that the positioning pressure plate 317 and the sliding pressure plate 315 no longer clamp the wire.

[0040] The feeding motor 201 is started, which drives the rotating frame 202 to rotate. This causes the bidirectional hydraulic cylinder 205, clamping plate 206, friction plate 207, and the coil 106 held by the two friction plates 207 to rotate 180 degrees. Then, the lifting motor 203 drives the feeding screw 211 to rotate, which causes the feeding slide 204 to slide on the rotating frame 202, causing the coil 106 to move down and be inserted into the lower housing 105. Then, the bidirectional hydraulic cylinder 205 retracts its piston rod, and the feeding motor 201 drives the rotating frame 202 to reverse, causing the feeding slide 204, bidirectional hydraulic cylinder 205, and clamping plate 206 to return to their initial positions.

[0041] When flipped, the U-shaped plate 208 rotates to make way, and then the U-shaped plate 208 is reset under the elastic force of the torsion spring 210.

[0042] After the welded terminal 322 disengages from the limiting seat 321, the welding hydraulic cylinder 324 drives the lifting moving frame 318, the mating plate 325, and the push rod 319 to move downwards. The mating plate 325 drives the rotating disk 326 to move downwards, causing the spatial cylinder 327 to rotate, which in turn drives the gear 312 to rotate. After the push rod 319 moves downwards a preset distance, the terminal 322 in the unloading slide 320 slides in the inclined slide to the position corresponding to the push rod 319 for alignment. Then, the welding hydraulic cylinder 324 drives the push rod 319 to slide in the holes of the unloading slide 320 and the bracket 301, pushing the terminal 322 upwards to a preset position. Then, the push rod 319 stops moving. When the push rod 319 pushes the terminal 322 at its corresponding position upwards, it simultaneously restricts the unloading of the remaining terminals 322 in the unloading slide 320.

[0043] The welding motor 305 drives the welding screw 304 to reverse and drive the long slide 303 back to the initial position. During the process of the long slide 303 returning to the initial position, the gear 309 meshes with the fixed rack 310 again, so that the sliding pressure plate 315 and the lifting moving frame 318 return to the initial position.

[0044] After a housing 105 is assembled with a coil 106, the base frame 101 operates to move the housing 105 a preset distance, so that the next unassembled housing 105 moves to the corresponding position under the U-shaped plate 208. The glue injection component 103, in coordination with the base frame 101 operating with gaps, injects glue into the housing 105 with the coil 106 installed.
