Description

[0001] The invention relates to the technical field of mechanical devices, in particular to an automatic wire-laying type plate isolator. Background Art

[0002] Plate products such as tiles and precision-polished metals are usually transported in groups of multiple sheets stacked vertically on plate racks. The friction between the plates can easily cause wear on the precision-polished surface. In order to protect the polished surface of the plates, foam pads are usually placed between the plates for isolation before transportation. Currently, large factories often use suction cup manipulators to stack plates and manually place foam isolation pads, which is not only inefficient but also poses a risk of operator injury.

[0035] The wire taking-up servo motor 32 is installed above the wire taking-up machine bracket 31, and a synchronous pulley 2 38 is installed on the output shaft of the wire taking-up servo motor 32. The synchronous pulley 1 37 and the synchronous pulley 2 38 are connected by a synchronous belt 39, and the winding wheel 33 is driven to rotate by the synchronous belt transmission.

The motor driver, the main control chip 47 and the switch power supply 48 are installed in the distribution box housing 44, and the distribution box housing 44 is provided with an electrical installation rail 45 for installing various components.

[0038] The usage is:

[0039] Paying action:

[0040] The wire-releasing plate isolator is used in conjunction with a manipulator, and the initial state is: the winding wheel 33 is installed on the winding wheel hanging cylinder 34 under the suction force of the NdFeB strong magnet 42, the pressing lever on the wire-releasing mechanism 3 is opened, the nylon wire 8 is passed through the wire wheel 2 30, clamped between the rubber winding wheel 25 and the wire wheel 1 26, and the wire end is fixed on the plate bracket 6;

[0041] When the robot places a plate 7, a high-level signal is provided to the main control chip 47, and then the X-axis slide 12 drives the wire-releasing mechanism 3 to move half the width of the plate from left to right along the X-axis direction. At the same time, the wire-releasing mechanism 3 releases the nylon line 8 of half the width of the plate plus twice the height of the plate during this period, thereby laying a U-shaped isolation line on the surface of the plate. When the robot places the next plate 7, the two ends of the U-shaped line are clamped under the action of the gravity of the plate, and a gap of about 2mm is formed between the two plates 7 under the action of the nylon line 8. At the same time, a high-level signal is provided to the main control chip 47 again. The main control chip 47 controls the Y-axis slide 13 to drive the wire-releasing mechanism 3 to move forward a distance of the thickness of a plate, and controls the X-axis slide 12 to drive the wire-releasing mechanism 3 to move half the width of the plate from right to left along the X-axis direction. At the same time, the wire-releasing mechanism 3 releases the nylon line 8 of half the width of the plate plus twice the height of the plate again during this period to complete the second laying. This process is repeated until the last plate is placed, and the winding wheel 33 is removed and transported together with the plate.

[0042] Reeling action:

[0043] The initial state of the wire-receiving mechanism 4 is: the wire-receiving mechanism 4 is placed in the middle position above the plate 7, the winding wheel 33 is hung on the winding wheel hanging cylinder 34, and the nylon wire 8 is wound onto the winding wheel 33 through the ram-horn-shaped wire blocking fork 43;

[0044] The wire-winding servo motor 32 rotates under the action of the driving control mechanism 5 to drive the winding wheel 33 to wind up the wire. After each plate 7 is removed, the corresponding length of nylon wire 8 is automatically retracted onto the winding wheel 33. When the nylon wire 8 is tightened due to the pressure of the plate and the tension exceeds the torque of the torque limiter 36, the torque limiter 36 slips to prevent the motor from being blocked and burned. The wire-winding servo motor 32 continues to move until the last plate is removed. The wire-winding mechanism 4 recycles all the nylon wire 8 onto the winding wheel 33 for recycling. The ram-horn wire blocking fork 43 controls the left and right swing range of the nylon wire 8 so that the nylon wire 8 can be evenly wound onto the winding wheel 33.
