Description

Technical Field

[0001] The invention relates to the technical field of transformer assembly equipment, and in particular to a manufacturing technology for a transformer iron core. Background Art

[0002] At present, the stacking of transformer cores in China is mainly done manually. The emergence of automatic core stacking production lines has broken the traditional core manufacturing method. In order to realize automatic core stacking, the silicon steel sheets of each core column need to be stored in a certain order. The silicon steel sheets of the same specifications in each material bin usually have one silicon steel sheet material bin for the left core column, right core column, upper yoke, and lower yoke. Since the upper and lower ends of the silicon steel sheets of the middle column need to be staggered, three silicon steel sheet material bins are usually required for the middle column, resulting in a large space occupied by the silicon steel sheet material bin of the middle column, and the need to add robots, which increases costs. Summary of the invention

[0003] The technical problem to be solved by the present invention is: the present invention provides a transformer silicon steel sheet reverse transfer mechanism and a center column stacking device, which overcomes the problems existing in the above-mentioned prior art. Through the transformer silicon steel sheet reverse transfer mechanism, the material warehouse and the transportation robot are reduced, the space occupied by the transformer core automatic stacking production line is reduced, and the operation is stable.

[0004] The technical solution adopted to solve the above technical problems is:

[0005] A transformer silicon steel sheet moving mechanism comprises a fixed plate, a lateral drive device is arranged on the fixed plate, a rotating mechanism is arranged on the lateral drive device, the rotating mechanism can rotate at least 180 degrees, the rotating mechanism is connected to a reversal plate, and a vacuum suction cup is arranged on the reversal plate.

[0006] Preferably, the transverse driving device is a displacement cylinder transversely fixed on the fixed plate, the rotating mechanism is a rotating cylinder, and the output shaft of the displacement cylinder is fixedly connected to the rotating cylinder.

[0007] In actual use, there are many working methods of the vacuum suction cup. For example, the vacuum suction cup is connected to the vacuum pump through the suction pipe, and the negative pressure is generated by the vacuum pump to suck the silicon steel sheet. When the vacuum pump stops working and releases the negative pressure, the vacuum suction cup releases the silicon steel sheet. When the negative pressure is released, the vacuum suction cup releases the silicon steel sheet. Vacuum pump system: Install a two-position three-way solenoid valve for vacuum on the negative pressure suction pipeline, power on for suction, and power off for deflation.

[0008] The transformer silicon steel sheet moving mechanism adopts a lateral drive and rotation mechanism structure, which has a compact structure and smooth operation, and effectively realizes the function of moving and flipping in one step.

[0009] The center column stacking device comprises the above-mentioned transformer silicon steel sheet moving mechanism and two left and right center column sheet bins. The center column sheet bin is a material bin for placing and discharging center column silicon steel sheets of various specifications. A center column silicon steel sheet conveying station is arranged between the two sheet bins. A gantry truss device is arranged. The crossbeam of the gantry truss device is located above the center column silicon steel sheet conveying device. Left and right stacking robots are respectively installed on the crossbeam. Special sheet picking and placing tool devices are installed at the ends of the stacking robots. The fixing plate of the transformer silicon steel sheet moving mechanism is installed on the crossbeam. The transformer silicon steel sheet moving mechanism is located on one side of one of the center column sheet bins.

[0010] When the lateral drive device is extended, the reversal plate is located above the middle column silicon steel sheet conveying device, and the special pick-and-place tool device of the stacking robot sends the silicon steel sheet in the middle column bin at this position to the vacuum suction cup on the reversal plate. When the vacuum suction cup contacts the silicon steel sheet, the vacuum pump works to generate negative pressure in the suction pipe. The vacuum suction cup simultaneously sucks the silicon sheet, and the rotating mechanism rotates 180 degrees. The vacuum pump stops working, the suction pipe releases the negative pressure, and the vacuum suction cup releases the silicon steel sheet, and the silicon steel sheet falls smoothly on the middle column silicon steel sheet conveying station. When the silicon steel sheet does not need to be flipped, the special pick-and-place tool device of the stacking robot can directly send the silicon steel sheet in the middle column bin at this position to the middle column silicon steel sheet conveying station. This structure adopts the reverse transfer mechanism of transformer silicon steel sheets, which can reduce at least one middle column bin, and two middle column bins can meet the requirements, reduce the space occupied by the transformer core automatic stacking production line, and facilitate the arrangement at the production site.

[0011] Preferably, the sheet picking and placing tool device installed at the end of the robot includes a suction cup fixing plate and a material picking suction cup installed under the suction cup fixing plate.

[0012] Preferably, the middle column silicon steel sheet conveying device includes a fixed frame and a conveying suction cup on the fixed frame, and is provided with a power device capable of driving the fixed frame to move back and forth in a straight line.

[0013] The present invention adopts a suction cup structure with stable adsorption force, can conveniently adsorb and transport silicon steel sheets, and improves work efficiency.

[0014] The beneficial effects of the present invention are as follows: the transformer silicon steel sheet shifting mechanism of the present invention adopts a lateral drive and rotation mechanism structure, has a compact structure, operates smoothly, and effectively realizes the function of one-step shifting and flipping. The middle column stacking device adopts a transformer silicon steel sheet reverse shifting mechanism, reduces the space occupied by the transformer core automatic stacking production line, reduces the number of transport robots, is convenient to arrange at the production site, has a high degree of automation, and improves production efficiency.
