Description
Technical Field
[0001] The invention relates to the technical field of marking devices, and in particular to a marking device for processing aluminum electrolytic capacitors. Background Art
[0002] Aluminum electrolytic capacitor is a capacitor with aluminum foil as electrode, anodized aluminum oxide film as dielectric, and electrolyte as cathode. It uses the dielectric properties of the extremely thin aluminum oxide dielectric layer on the surface of the anode aluminum foil to store charge. From an electrical point of view, when voltage is applied to the two electrodes of the capacitor, an electric field will be formed between the two electrodes, and the charge is stored in this electric field.

[0022] Working principle: When the present invention is used, the aluminum electrolytic capacitor is first placed in the middle of the top surface of the workbench 12, and then the handle is turned to drive the bidirectional screw rod 35 to rotate, thereby driving the threaded sleeve 36 to move relative to each other, thereby driving the clamping plate 14 to move relative to each other, and the aluminum electrolytic capacitor is fixed by the clamping force between the two clamping plates 14; Then, the long electric push rod 19 is opened, wherein the initial end of the movable end of the long electric push rod 19 (recorded as point A) moves to the position (recorded as point B) where the aluminum electrolytic capacitor rotates 360°; and the end of the movable end of the long electric push rod 19 (recorded as point C) drives the rectangular frame 26 to move by the extension of the movable end of the long electric push rod 19, and the movement of the rectangular frame 26 is divided into two processes; Process 1: First, open the micro electric push rod 21, and the fixed rod 23 is driven to contract by the contraction of the movable end of the micro electric push rod 21, so that the fixed rod 23 is separated from the fixing hole 25, and the fixing of the strip tooth plate 24 is released; Then, the movable end of the long electric push rod 19 is moved from point A to point B. At this time, under the action of the extrusion spring 27, the movable block 28 moves synchronously with the rectangular frame 26, thereby driving the bar-shaped toothed plate 24 to move, thereby driving the gear 18 and the connecting shaft 13 to rotate, and further realizing the rotation of the workbench 12, thereby driving the aluminum electrolytic capacitor to rotate; When the position where the aluminum electrolytic capacitor needs to be marked is coplanar with the laser marker 11, the long electric push rod 19 stops working, and then the movable end of the micro electric push rod 21 is controlled to extend so that the fixing rod 23 is inserted into the fixing hole 25 on the strip tooth plate 24 to fix the strip tooth plate 24; Process 2: Control the movable end of the long electric push rod 19 to move from point B to point C. In this process, the rectangular frame 26 squeezes the connecting frame 17, thereby driving the piston 33 to move, so that the gas in the sealing box 16 is transported to the bellows 8 through the outlet pipe 29, and then the wind is blown to the marking head of the laser marker 11 through the outlet pipe 10; Then, the movable end of the long electric push rod 19 moves from point C to point B, at which time the rectangular frame 26 is separated from the connecting frame 17, and then the piston 33 is reset under the action of the reset spring 32, and at this time, the outside air enters the sealing box 16 through the intake pipe 30; The movable end of the long electric push rod 19 moves back and forth between point B and point C, so as to continuously blow air to the marking head of the laser marker 11, thereby achieving air cooling of the marking part of the aluminum electrolytic capacitor; When marking the aluminum electrolytic capacitor, the drive motor 7 is started first, and the output shaft of the drive motor 7 drives the long screw rod 5 to rotate, thereby driving the threaded sleeve 4 to rise and fall, thereby driving the electric telescopic rod 2 to rise and fall, and further driving the laser marker 11 to rise and fall; the laser marker 11 is moved to the aluminum electrolytic capacitor in parallel with the marking position by controlling the drive motor 7; then, the electric telescopic rod 2 is opened, and the active end of the electric telescopic rod 2 is extended to drive the laser marker 11 to move, so that the marking head of the laser marker 11 contacts the aluminum electrolytic capacitor to achieve marking.
