Description

Technical Field

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

[0002] The three-dimensional storage device consists of multiple layers of vertical shelves, a board handling robotic arm, a conveying system, and a central control system. After receiving order information through the central control system, the robotic arm moves along the guide rail to the target shelf layer, grabs the board using a vacuum suction cup or a 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 likely to accumulate on the surface of the board, mainly from processing residues, environmental floating dust, and particles generated by mechanical friction. The attachment of dust not only affects the surface quality of the board but may also block the vacuum adsorption holes of the handling mechanism, reducing the positioning accuracy; dust poses an explosion hazard in a closed storage environment.

[0004] Capacitive sensors detect dust attachment based on the capacitance value offset caused by changes in the dielectric constant. A capacitive sensor usually consists 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, resulting in a change in the equivalent capacitance value. By measuring the capacitance change and comparing it with a preset threshold, the degree of dust accumulation can be judged.

[0005] In the storage scenario of customized furniture boards, there are significant differences in the thickness of the boards, which directly affects the detection accuracy of capacitive sensors. Since the capacitance value is inversely proportional to the thickness of the medium between the electrode plates, boards of different thicknesses will form different reference capacitance values, resulting in the possibility that the tiny capacitance changes caused by dust may be masked by the thickness difference noise. In addition, the non-uniformity of the board material and internal structure will further interfere with the electric field distribution, causing misjudgment. Summary of the Invention

[0006] In order to improve the problem of dust measurement deviation caused by the differences in the thickness and material of customized furniture boards, the present application provides an intelligent three-dimensional storage device for customized furniture boards.

Detailed implementation mode

[0041] The following will further describe this application in detail with reference to the Figures 1-4 accompanying drawings.

[0042] The embodiment of this application discloses an intelligent three-dimensional storage device for customized furniture boards. The three-dimensional storage device includes a shelf 1 and a plurality of sliding plates 2 slidably arranged in the shelf 1. The three-dimensional storage device is formed by splicing a plurality of shelves 1 in a straight line. The shelf 1 is composed of a plurality of bins 3 spliced vertically; the sliding plate 2 is slidably arranged in the bin 3, and the boards are stored by stacking them on the top surface of the sliding plate 2.

[0043] The bin 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 rod 5 and the base 4 enclose a cuboid; the sliding plate 2 is slidably connected to the base 4. A partition 7 is slidably connected vertically inside the top seat 6. Specifically, a chute 9 is opened on the bottom surface of the top seat 6, and the partition 7 is slidably arranged in the chute 9. A return spring is fixedly arranged in the chute 9, and the end of the return spring is fixedly connected to the partition 7 for driving the partition 7 to reset upward.

[0044] A plurality of magnetic sheets I 19 are fixedly arranged at the bottom of the bin 3; the magnetic sheets I 19 are located below the partition 7, and a metal sheet magnetically adsorbable to the magnetic sheets I 19 is fixedly arranged at the bottom of the partition 7. A plurality of dust suction pipes 8 are fixedly arranged at the top of the bin 3, and the dust suction pipes 8 are connected to a dust storage chamber through a dust suction pump. The dust suction pump is connected to a power supply through a contact switch I, and a plurality of dust suction pumps are connected in parallel. The contact switch I is arranged in the chute 9; after the partition 7 moves upward, it disconnects the contact switch I by abutting against it; after the partition 7 moves downward, it separates from the contact switch I to make it closed. Specifically, after the magnetic sheets I 19 are energized, the partition 7 is magnetically adsorbed to move downward; after all the partitions 7 on the periphery of the bin 3 move downward, a closed space is formed in the bin 3; at the same time, the partition 7 separates from the contact switch I, and the dust suction pump starts to dust the bin 3.

[0045] A capacitance sensor is arranged inside the bin grid 3; the capacitance sensor includes a receiving electrode plate fixedly arranged on the bottom surface of the top seat 6 and a transmitting electrode plate fixedly arranged on the top surface of the bottom seat 4. The transmitting electrode plate is connected to the positive pole of the power supply, and the receiving electrode plate is grounded through a fixed resistor; a control switch and a contact switch II are arranged on the connection circuit between the transmitting electrode plate and the power supply. The control switch and the contact switch II are connected in parallel, and the transmitting electrode plate is conducted with the power supply after any one of them is closed. The contact switch II is connected to the input end of a timer I, and the output end of the timer I is connected to the transmitting electrode plate; after the circuit of the contact switch II is conducted, the timer I starts timing and controls the transmitting electrode plate to be powered on, and the contact switch II is disconnected after the timer I finishes timing. The grounding end of the receiving electrode plate is connected to the input end of an amplifier, and the output end of the amplifier is connected to the magnetic plate II 16; the other end of the magnetic plate II 16 is connected to the positive pole of the power supply.

[0046] Preferably, the output end of the amplifier is connected to the gate of a MOS transistor, the source electrode of the MOS transistor is connected to the magnetic plate II 16, and the drain electrode is grounded; a current limiting resistor is connected in series between the output end of the amplifier and the MOS transistor. A freewheeling diode is connected in parallel to the magnetic plate II 16. An increase in dust on the surface of the to-be-tested sheet will cause the capacitance measured by the capacitance sensor to increase, the input voltage of the amplifier to rise, the current flowing through the MOS transistor to increase, and the magnetism of the magnetic plate II 16 to enhance.

[0047] The magnetic plate II 16 is arranged inside the conductor tube 12. The conductor tube 12 is a hollow circular tube, and several conductor tubes 12 are respectively arranged inside the shelf 1. A metal rod 13 is fixedly arranged inside 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 conduit 14 and an insulating tube 15 are slidably arranged inside the conductor tube 12; the conduit 14 is sleeved on the periphery of the metal rod 13, and the insulating tube 15 is sleeved on the periphery of the conduit 14. The magnetic plate II 16 is fixedly connected to the inner bottom surface of the conductor tube 12; metal sheets magnetically adsorbed to the magnetic plate II 16 are respectively fixedly arranged at the end parts of the conduit 14 and the insulating tube 15; tension springs 10 are respectively fixedly arranged at the end parts of the conduit 14 and the insulating tube 15 far away from the magnetic plate II 16; the end parts of the tension springs 10 are fixedly connected to the inner bottom surface of the conductor tube 12 far away from the magnetic plate II 16 and are used for driving the conduit 14 or the insulating tube 15 to reset in the direction away from the magnetic plate II 16. A guiding groove 17 is axially formed on the inner peripheral surface of the conductor tube 12, and the insulating tube 15 is slidably arranged inside the guiding groove 17.

[0048] Specifically, the elastic coefficients of the first tension spring connected to the conduit 14 and the second tension spring connected to the insulating tube 15 are the same; and in the initial state, the end faces of the conduit 14 and the insulating tube 15 close to the magnetic plate II 16 are flush. After the magnetic plate II 16 is powered on, the conduit 14 and the insulating tube 15 move equal distances in the direction close to the magnetic plate II 16 due to magnetic adsorption.

[0049] A magnetic ring 18 is fixedly arranged on the inner peripheral surface of the guide groove 17, and a metal ring magnetically adsorbed to the magnetic ring 18 is fixedly arranged on the outer peripheral surface of the insulating tube 15; the magnetic ring 18 is an electromagnet, and after the magnetic ring 18 is electrified, it magnetically adsorbs the metal ring to fix the metal ring 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 second magnetic piece 16. The magnetic ring 18 is connected to the second contact switch; specifically, the second contact switch is connected to the second timer, the output end of the second timer is connected to the coil of the first relay, and the magnetic ring 18 is connected to the normally closed contact of the first relay. After the second contact switch is closed, the second timer starts timing. After the second timer finishes timing, it sends a low level to the first relay, and the first relay controls the magnetic ring 18 to close.

[0050] Specifically, the second contact switch is arranged on the inner wall of the bin compartment 3; after the sliding plate 2 retracts into the bin compartment 3, it abuts against the second contact switch. When the sliding plate 2 is separated from the second contact switch, the second contact switch is in an open state, otherwise the second contact switch is closed. After the plate is placed on the sliding plate 2 and received into the bin compartment 3, the sliding plate 2 abuts against the second contact switch to make it in a conducting state; both the first timer and the second timer start timing. After the emitting electrode plate is electrified, a current passes through the second magnetic piece 16, and the current passing through the second magnetic piece 16 in this state is the initial current; the catheter 14 and the insulating tube 15 are magnetically adsorbed by the second magnetic piece 16 and move against the tensile spring 10; after the catheter 14 and the insulating tube 15 move, the end faces of the two still remain flush. In the initial state, there is no dust / less dust on the surface of the plate. After the second timer finishes timing, the magnetic ring 18 is electrified and magnetically fixes the insulating tube 15; after the first timer finishes timing, the second magnetic piece 16 is powered off, and after the insulating tube 15 is fixed, it maintains a displaced state, and the catheter 14 is reset under the action of the tensile spring 10.

[0051] A spiral resistance wire is fixedly arranged on the inner peripheral surface of the insulating tube 15. A sliding piece 11 is embedded on the catheter 14, the sliding piece 11 is sleeved on the outer peripheral surface of the metal rod 13, and the sliding piece 11 is in electrical contact with the metal rod 13 and the resistance wire respectively. Connecting terminals are arranged at at least one end of the metal rod 13 and both ends of the resistance wire respectively, so that the insulating tube 15, the metal rod 13 and the sliding piece 11 form a sliding rheostat.

[0052] Specifically, the control switch is controlled to be closed manually or by a controller. After the control switch is closed, the catheter 14 is displaced by the magnetic adsorption of the second magnetic piece 16, and in this state, the insulating tube 15 is fixed by the magnetic adsorption 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, the magnetism of the second magnetic piece 16 increases, resulting in an increase in the displacement distance of the catheter 14 towards the second magnetic piece 16, and the displacement distance of the sliding piece 11 increases following the catheter 14.

[0053] The sliding rheostat composed of the sliding piece 11, the metal rod 13 and the resistance wire is connected to the magnetic piece 19 through the comparator and the relay two. Specifically, one end of the resistance wire close to the magnetic piece 16 is connected to the positive pole of the power supply, and the other end is grounded; the metal rod 13 is connected to the positive-phase input terminal of the comparator, the reverse-phase input terminal of the comparator is connected to the reference voltage, and the output terminal is connected to the coil of the relay two; the other end of the coil of the relay two is grounded, and the magnetic piece 16 is connected to the normally open contact of the relay two. Specifically, when the sliding piece 11 moves in the direction close to the magnetic piece 16, the input voltage of the comparator increases; the increase in the magnetism of the magnetic piece 16 causes an increase in the displacement distance of the sliding piece 11. When the input voltage of the comparator is greater than the threshold voltage, the comparator outputs a high level to the relay two, and the relay two controls the start of the magnetic piece 19. After the magnetic piece 19 is energized, it moves the partition plate 7 downward through magnetic adsorption, and the movement of the partition plate 7 triggers the contact switch one, and the dust suction pump is energized to remove dust.

[0054] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
