Description

Technical Field

[0001] The present application relates to the technical field of storage device cleaning, and in particular to an intelligent three-dimensional storage device for customized furniture panels. Background Art

[0002] The three-dimensional storage device consists of multiple vertical shelves, sheet material handling robotic arms, a conveying system and a central control system. After the device receives order information through the central control system, the robotic arm moves along the guide rail to the target shelf layer, grabs the sheet material with a vacuum suction cup or clamping mechanism, and transfers it to the designated workstation through the conveying system.

[0003] During the long-term operation of the three-dimensional storage device, dust or debris is easy to accumulate on the surface of the plate, mainly from processing residues, environmental dust and particles generated by mechanical friction. Dust adhesion not only affects the surface quality of the plate, but also may block the vacuum adsorption holes of the handling mechanism and reduce positioning accuracy; dust in a closed storage environment poses an explosion hazard.

[0004] Capacitive sensors detect dust adhesion based on the capacitance value offset caused by the change in dielectric constant. Capacitive sensors are usually composed of a pair of parallel electrode plates. When dust particles exist between the electrode plates, the dielectric properties of the dust will change the distribution of the electric field between the plates, causing the equivalent capacitance value to change. By measuring the capacitance change and comparing it with the preset threshold, the degree of dust accumulation can be determined.

[0005] In the storage scenario of custom furniture plates, there are significant differences in plate thickness, which directly affects the detection accuracy of the capacitive sensor. Since the capacitance value is inversely proportional to the thickness of the medium between the plates, plates of different thicknesses will form differentiated baseline capacitance values, resulting in the possibility that small capacitance changes caused by dust may be masked by thickness difference noise. In addition, the material and internal structure of the plate are not uniform, which will further interfere with the electric field distribution and cause misjudgment. Summary of the invention

DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-4This application is described in further detail.

[0026] The embodiment of the present application discloses an intelligent three-dimensional storage device for customized furniture panels. The three-dimensional storage device includes a shelf 1 and a plurality of slides 2 slidably arranged in the shelf 1.

The shelf 1 is composed of a plurality of compartments 3 spliced ​​vertically; the slide 2 is slidably arranged in the compartment 3, and the panels are stored by stacking on the top surface of the slide 2.

[0027] The compartment 3 includes a base 4, a plurality of vertical rods 5 fixedly connected to the base 4, and a top seat 6 fixedly arranged above the base 4. In this embodiment, the top seat 6, the vertical rods 5 and the base 4 are arranged to form a rectangular parallelepiped; the slide plate 2 is slidably connected to the base 4. A partition 7 is vertically slidably connected inside the top seat 6. Specifically, a slide groove 9 is provided on the bottom surface of the top seat 6, and the partition 7 is slidably arranged in the slide groove 9. A reset spring is fixedly arranged in the slide groove 9, and the end of the reset spring is fixedly connected to the partition 7, which is used to drive the partition 7 to reset upward.

[0028] Several magnetic sheets 19 are fixedly provided at the bottom of the compartment 3; the magnetic sheets 19 are located below the partition 7, and a metal sheet that can be magnetically adsorbed to the magnetic sheets 19 is fixedly provided at the bottom of the partition 7. Several dust suction pipes 8 are fixedly provided at the top of the compartment 3, and the dust suction pipes 8 are connected to the dust storage compartment through a dust suction pump. The dust suction pump is connected to the power supply through a contact switch 1, and several dust suction pumps are connected in parallel. The contact switch 1 is set in the slide groove 9; after the partition 7 moves upward, it is disconnected by abutting against the contact switch 1; after the partition 7 moves downward, it is separated from the contact switch 1 to close it. Specifically, after the magnetic sheet 19 is energized, the partition 7 is moved downward by magnetically adsorbing the partition 7; the partitions 7 on the sides of the compartment 3 are all moved downward to form a closed space for the compartment 3; at the same time, the partition 7 is separated from the contact switch 1, and the dust suction pump is started to remove dust from the compartment 3.

[0029] A capacitive sensor is arranged in the compartment 3; the capacitive sensor includes a receiving plate fixed on the bottom surface of the top seat 6 and an emitting plate fixed on the top surface of the base 4. The emitting plate is connected to the positive pole of the power supply, and the receiving plate is grounded through a fixed resistor; a control switch and a contact switch 2 are arranged on the connection circuit between the emitter plate and the power supply. The control switch and the contact switch 2 are connected in parallel, and the emitter plate is turned on to the power supply after any one of them is closed. The contact switch 2 is connected to the input end of the timer 1, and the output end of the timer 1 is connected to the emitter plate; after the circuit of the contact switch 2 is turned on, the timer starts timing, and controls the emitter plate to be energized, and the contact switch 2 is disconnected after the timer 1 ends timing. The grounding end of the receiving plate is connected to the input end of the amplifier, and the output end of the amplifier is connected to the magnetic sheet 2 16; the other end of the magnetic sheet 2 16 is connected to the positive pole of the power supply.

[0030] Preferably, the output end of the amplifier is connected to the gate of the MOS tube, the source of the MOS tube is connected to the second magnetic sheet 16, and the drain is grounded; a current limiting resistor is connected in series between the output end of the amplifier and the MOS tube. A freewheeling diode is connected in parallel to the second magnetic sheet 16. The increase of dust on the surface of the plate to be tested will cause the capacitance measured by the capacitive sensor to increase, so that the input voltage of the amplifier increases, the current flowing through the MOS tube increases, and the magnetism of the second magnetic sheet 16 is enhanced.

[0031] Magnetic piece 2 16 is arranged in the conductor tube 12. The conductor tube 12 is a hollow circular tube, and several conductor tubes 12 are respectively arranged in the shelf 1. A metal rod 13 is fixed in the conductor tube 12, and the metal rod 13 extends along the axial direction of the conductor tube 12 and is coaxially arranged with the conductor tube 12. A guide tube 14 and an insulating tube 15 are slidably arranged in the conductor tube 12; the guide tube 14 is sleeved on the circumference of the metal rod 13, and the insulating tube 15 is sleeved on the circumference of the guide tube 14. Magnetic piece 2 16 is fixed to the inner bottom surface of the conductor tube 12; the ends of the guide tube 14 and the insulating tube 15 are respectively fixed with metal pieces magnetically attracted to magnetic piece 2 16; the ends of the guide tube 14 and the insulating tube 15 away from magnetic piece 2 16 are respectively fixed with tension springs 10; the end of the tension spring 10 is fixed to the inner bottom surface of the conductor tube 12 away from magnetic piece 2 16, and is used to drive the guide tube 14 or the insulating tube 15 to reset in the direction away from magnetic piece 2 16. A guide groove 17 is formed on the inner peripheral surface of the conductor tube 12 along its axial direction, and the insulation tube 15 is slidably disposed in the guide groove 17 .

[0032] Specifically, the elastic coefficients of the tension spring 1 connected to the conduit 14 and the tension spring 2 connected to the insulating tube 15 are the same; and in the initial state, the end surfaces of the conduit 14 and the insulating tube 15 close to the second magnetic sheet 16 are flush. After the second magnetic sheet 16 is powered on, the conduit 14 and the insulating tube 15 move an equal distance toward the direction close to the second magnetic sheet 16 due to magnetic attraction.

[0033] A magnetic ring 18 is fixedly provided on the inner circumference of the guide groove 17, and a metal ring that is magnetically attracted to the magnetic ring 18 is fixedly provided on the outer circumference of the insulating tube 15; the magnetic ring 18 is an electromagnet, and after the magnetic ring 18 is energized, the metal ring is magnetically attracted to the magnetic ring, so that the metal ring is in a fixed state. It should be noted that the length of the magnetic ring 18 is less than the length of the insulating tube 15, and the magnetic ring 18 is located on the moving path of the insulating tube 15 to reduce the magnetic field interference of the magnetic ring 18 on the magnetic sheet 2 16. The magnetic ring 18 is connected to the contact switch 2; specifically, the contact switch 2 is connected to the timer 2, the output end of the timer 2 is connected to the coil of the relay 1, and the magnetic ring 18 is connected to the normally closed contact of the relay 1. After the contact switch 2 is closed, the timer 2 starts timing, and after the timer 2 ends timing, it sends a low level to the relay 1, and the relay 1 controls the magnetic ring 18 to close.

[0034] Specifically, contact switch 2 is arranged on the inner wall of compartment 3; after slide plate 2 is retracted into compartment 3, it abuts against contact switch 2. When slide plate 2 is separated from contact switch 2, contact switch 2 is in an open state, otherwise contact switch 2 is closed. After the plate is placed on slide plate 2 and accommodated in compartment 3, slide plate 2 abuts against contact switch 2 to make it in a pass state; timer 1 and timer 2 both start timing. After the emitter plate is energized, current passes through magnetic sheet 2 16, and the current passing through magnetic sheet 2 16 in this state is the initial current; conduit 14 and insulating tube 15 are moved by magnetic adsorption of magnetic sheet 2 16 to overcome tension spring 10; after conduit 14 and insulating tube 15 move, the end faces of both remain flush. In the initial state, there is no dust or less dust on the surface of the plate. After timer 2 ends, magnetic ring 18 is energized and magnetically fixes insulating tube 15; after timer 1 ends, magnetic sheet 2 16 is de-energized, insulating tube 15 is fixed and remains in a displacement state, and conduit 14 is reset by tension spring 10.

[0035] A spiral resistance wire is fixed on the inner circumference of the insulating tube 15. A sliding piece 11 is embedded in the conduit 14, and the sliding piece 11 is sleeved on the outer circumference of the metal rod 13, and the sliding piece 11 is in electrical contact with the metal rod 13 and the resistance wire respectively. At least one end of the metal rod 13 and both ends of the resistance wire are respectively provided with terminal blocks, so that the insulating tube 15, the metal rod 13 and the sliding piece 11 constitute a sliding rheostat.

[0036] Specifically, the control switch is controlled to close manually or by a controller. After the control switch is closed, the conduit 14 is displaced by the magnetic attraction of the second magnetic piece 16, and in this state, the insulating tube 15 is in a fixed state by the magnetic attraction of the magnetic ring 18. When dust accumulates on the surface of the plate, the dielectric constant between the plates increases, the capacitance value increases, and the magnetism of the second magnetic piece 16 increases, resulting in an increase in the displacement distance of the conduit 14 in the direction of the second magnetic piece 16, and the displacement distance of the slide 11 following the conduit 14 increases.

[0037] The sliding rheostat composed of the slider 11, the metal rod 13 and the resistance wire is connected to the magnetic sheet 19 through the comparator and the relay 2. Specifically, the resistance wire is connected to the positive pole of the power supply at one end close to the magnetic sheet 2 16, and the other end is grounded; the metal rod 13 is connected to the positive input end of the comparator, the negative input end of the comparator is connected to the reference voltage, and the output end is connected to the relay 2 coil; the other end of the relay 2 coil is grounded, and the magnetic sheet 2 16 is connected to the normally open contact of the relay 2. Specifically, when the slider 11 moves toward the direction close to the magnetic sheet 2 16, the input voltage of the comparator increases; the magnetic enhancement of the magnetic sheet 2 16 causes the displacement distance of the slider 11 to increase. When the input voltage of the comparator is greater than the threshold voltage, the comparator outputs a high level to the relay 2, and the relay 2 controls the magnetic sheet 19 to start. After the magnetic sheet 19 is energized, it moves downward through the magnetic adsorption partition 7, and the movement of the partition 7 triggers the contact switch 1, and the dust suction pump is energized to remove dust.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
