Technical Field

[0001] This utility model relates to an edge-binding machine, specifically an automatic edge-binding machine for steel grid-type resistor sheets. Background Technology

[0002] With rapid industrialization and urbanization, the demand for electricity is enormous, and the power grid, as the carrier of power transmission and consumption, has become a key component of the energy supply system. However, my country has a vast territory and uneven distribution of power resources. The construction of ultra-high voltage (UHV) power grids will effectively guarantee the coordinated development of power and the economy and society, and achieve the sustainable development of the power industry. Steel-grid resistor elements are a key component ensuring high-quality power transmission in UHV power grids.

[0003] The current packaging and testing of steel-grid resistor chips is carried out manually in a single process, which mainly includes the following steps:

[0004] Process 1

[0005] 1. Assembly of stainless steel sheet and mica sheet

[0006] 2. Stainless steel sheet + mica sheet combined molding

[0007] 3. Finished edge binding sheet storage

[0008] Process Two

[0009] 1. Steel grid resistor element in place

[0010] 2. Insulation separation of steel grid resistor elements

[0011] 3. Assembly of steel grid resistor elements and edge-sealing plates

[0057] Working principle:

[0058] The operator places the steel grid resistor element on the pneumatic slide table 2, clamps it with the clamping mechanism 7, and the grid teeth automatically lift to separate the steel grid bars. The first pneumatic vacuum arm 6 moves the mica spacer bar, and the cylinder 5 pushes the mica spacer bar so that the mica spacer bar can be inserted into the blades of the steel grid resistor element. The grid teeth are lifted back to their original position, and the pneumatic slide table 2 transports the steel grid resistor element with the mica spacer bar inserted to the packaging position to wait.

[0059] The servo slide 7 drives the second pneumatic vacuum arm 8 to simultaneously adsorb stainless steel sheets and mica sheets, which are then sequentially fed into the forming mold 10 for stacking and then retracted to the adsorption position to wait. The hydraulic station drives the downward pressing cylinder 13 to push the forming block 11 downward, so that the stainless steel sheets and mica sheets are formed in the forming mold 10. After the forming block 11 is formed, it moves upward back to its original position to wait.

[0060] The hydraulic station drives the edge sealing mechanism 6 to move to the sealing position, inserts the steel grid resistor element with mica spacer into the forming mold, and the upper forming cylinder 18 drives the upper forming mechanism 16 to move directly above the forming mold 10. The forming cylinder presses against the forming mold 10. After the edge sealing is completed, the upper forming mechanism 16 returns to its original position, the edge sealing mechanism 6 returns to its original position, and the forming mold 10 rotates from the horizontal position to the vertical position.

[0061] The pneumatic slide 2 retracts from the packaging position to the loading and inspection position. The cylinder drives the withstand voltage tester's test pen to contact the steel grid resistor and the edge piece of the steel grid resistor sheet respectively. The withstand voltage tester outputs 2500V voltage for withstand voltage testing. After completion, the clamping mechanism 7 opens, and the operator removes the steel grid resistor sheet and puts in the steel grid resistor element, and the production cycle continues.
