[0019] like Figure 1 The dry-type transformer foil winding coil pressing line shown includes a feeding mechanism 2, a pressing mechanism 3, and a transfer mechanism 4 arranged in sequence. The feeding mechanism 2 is used to automatically feed the transformer coil 1. The pressing mechanism 3 is correspondingly arranged at the output end of the feeding mechanism 2 and is used to press the transformer coil 1. The transfer mechanism 4 is correspondingly arranged at the output end of the pressing mechanism 3 and is used to send the pressed transformer coil 1 to the subsequent work station.

[0020] Specifically, in combination Figure 2 As shown, the feeding mechanism includes a first transmission chain 204 capable of supporting the transformer coil and a first drive assembly capable of driving the first transmission chain 204. The first transmission chain 204 is mounted on a base 201 and is a double-row parallel chain. The bottom support of the transformer coil 1 is placed on the first transmission chain 204. The first drive assembly includes a servo motor 202 and a sprocket assembly 203. The servo motor 202 is connected to the chain through the sprocket assembly 203. The servo motor 202 drives the transformer coil forward through the chain. The first transmission chain 204 is also equipped with... A guiding mechanism is provided for limiting and guiding both sides of the transformer coil. The guiding mechanism includes a pair of guide frames 205 and a plurality of guide rollers 206 disposed within the guide frames 205. During the forward conveying of the transformer coil 1, the guide rollers 206 can limit and guide both sides of the transformer coil 1 to ensure its stability during the conveying process. In addition, a first blocking bracket 207 is provided on the front side of the feeding mechanism to block the transformer coil 1. The first blocking bracket 207 can position the front side of the transformer coil 1 and also prevent it from falling off the first transmission chain 204 to ensure safety.

[0021] Specifically, in combination Figure 3As shown, the pressing mechanism includes a lifting frame 302, a first lifting drive assembly, a pad 304, a second transmission chain 303, a second drive assembly, a bracket 306, a pressure plate 305, and a second lifting drive assembly. The second transmission chain 303 is correspondingly disposed at the outlet end of the first transmission chain 204 and is fixed to the top of the lifting frame 302. The second drive assembly includes a servo motor and a sprocket assembly, and can drive the second transmission chain 303 to rotate. The lifting frame 302 and the first lifting drive assembly are disposed on a base plate 301. The first lifting drive assembly is connected to the lifting frame 302 and uses a hydraulic cylinder. The pad 304 is disposed inside the lifting frame 302. The moving component can drive the lifting frame 302 and the second transmission chain 303 to move up and down, so that the transformer coil 1 on the second transmission chain 303 is supported by the pad 304. The bracket 306 is set above the second transmission chain 303, and the second lifting drive component is set on the bracket 306. The second lifting drive component includes a hydraulic cylinder 307 and a guide rod 308. The hydraulic cylinder 307 is connected to the pressure plate 305 through the guide rod 308. The hydraulic cylinder 307 can drive the pressure plate 305 to move up and down, thereby pressing the transformer coil 1 on the pad 304. In addition, the bracket 306 is also provided with a ladder 309 for maintenance of the pressing mechanism. Similarly, guide mechanisms are also provided on both sides of the second transmission chain 303.

A second blocking bracket that can block the transformer coil is provided on the rear side of the transfer mechanism 4, and guide mechanisms are also provided on both sides of the third transmission chain.

[0023] During processing, the transformer coil 1 is hoisted onto the loading mechanism 2 of the dry-type transformer foil winding coil pressing line by a crane. The transformer coil is positioned and centered by the guide mechanism and the first blocking bracket 207. The loading mechanism 2 automatically transfers the transformer coil 1 to the pressing mechanism 3. After it is in place, the operator sets the coil pressing stroke parameters, pressure, and holding time through the visual parameter setting interface. The first lifting drive component drives the lifting frame 302 and the second transmission chain 303 to descend, so that the transformer coil 1 falls on the pad 304. The transformer coil 1 is supported by the pad 304. At this time, the hydraulic cylinder 307 drives the pressure plate 305 to press down. After the pressure plate 305 reaches the preset stroke, the transformer coil 1 can be compacted. The equipment automatically measures the pressing height. After confirming that it is qualified, the lifting drive component drives the lifting frame 302 and the second transmission chain 303 to rise. The transformer coil 1 returns to the second transmission chain 303, which sends it to the transfer mechanism 4. The operator can directly tighten the nut on the top support of the transformer coil 1 to complete the operation.
