[0002] Pallets are usually used to place workpiece blanks in workshops, which facilitates the stacking of workpieces and the loading and unloading of forklifts. They are widely used in various factories today.

[0003] At present, pallets are mainly divided into wooden pallets, metal pallets and plastic pallets, which have different characteristics and are used in different scenarios. Among them, plastic pallets are light in texture and easy to place, so they are increasingly used in modern factories. However, they also have the disadvantage of relatively low strength. In order to improve the limitations of plastic pallets, some manufacturers have introduced solutions to add steel beams to plastic pallets to increase the strength of the pallets, so that they can have a higher load capacity. Specifically, a small amount of steel pipes are directly inserted into the plastic pallet, which will not increase the weight of the plastic pallet itself, but also improve the strength of the plastic pallet.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-2 The utility model provides the following technical solutions: a fully automatic cleaning device for plastic pallets, which is used for cleaning plastic pallets containing steel beams, comprises a cleaning unit 1 for cleaning the pallets, a conveyor line 2 for conveying the pallets, and a manipulator 3 for transferring the pallets between the conveyor line 2 and the cleaning unit 1; an electromagnet 4 is provided on the manipulator 3.

[0025] As an optional implementation scheme of the utility model, when a pallet is transmitted from the conveyor line 2, the manipulator 3 moves to the top of the pallet, turns on the electromagnet 4 and aligns it with the steel beam in the pallet, so that the pallet is sucked up by the manipulator 3, and then the manipulator 3 puts the pallet into the cleaning unit 1 for cleaning. After cleaning, the pallet is sucked up by the manipulator 3 and placed back on the conveyor line 2, so that the pallet moves to the discharge end along the conveyor line 2.

[0026] Through the above structure, the plastic pallet can be cleaned completely automatically without manual operation. In addition, by using the electromagnet 4, there is no need to worry about the robot 3 causing damage to the pallet. It is very suitable for continuous cleaning operations of plastic pallets containing steel beams.

[0027] like Figure 1 As shown, the robot 3 includes a robot arm 31 and a connecting rod 32 arranged on the robot arm 31 , and two electromagnets 4 are respectively arranged at two ends of the connecting rod 32 .

[0028] As an optional implementation scheme of the utility model, the robot arm 31 is an existing technology that has been widely used. As long as it can drive the connecting rod 32 to move back and forth between the cleaning box 11 and the conveyor line 2, those skilled in the art can select a suitable robot arm 31 according to actual needs, so this technical solution will not be described in detail. The two electromagnets 4 are mainly set to absorb different positions on the steel beam, or to absorb different steel beams on a pallet, so that the pallet maintains force balance during the transportation process of the robot arm 3, and is not prone to tipping accidents, making the transportation of the pallet between the cleaning unit 1 and the cleaning box 11 smoother and more stable.

[0029] like Figure 1 As shown, two connecting rods 32 are provided, and at least one connecting rod 32 is movably connected.

[0030] As an optional implementation scheme of the present invention, in order to further improve the reliability of the electromagnet 4 in sucking the pallet, two connecting rods 32 can be arranged in parallel (a total of four electromagnets 4 are carried), or two connecting rods 32 can be coaxial, and one of the connecting rods 32 is designed to be a movable connection in order to adapt to the different spacings between steel beams in pallets of different specifications. Therefore, the specific movable connection method can be a sliding connection, a telescopic connection, etc., and this is not specifically limited in the present technical solution. Any means for driving the adjustment of the spacing between the two connecting rods 32 should be included in the protection scope of this application.

[0031] like Figure 1-2 The figure also includes a telescopic mechanism 33 , which is connected to the mechanical arm 31 , and a connecting rod 32 is connected to the telescopic mechanism 33 .

[0032] As an optional implementation scheme of the present invention, the telescopic mechanism 33 mainly includes a structure such as an electric push rod, which enables the distance between the two connecting rods 32 to be adjustable, thereby adapting to the transportation of plastic pallets of different specifications.

[0033] like Figure 1-3 As shown, the cleaning unit 1 includes a cleaning box 11 and an ultrasonic module 12 in the cleaning box 11 . A water inlet 13 and a water outlet 14 are respectively provided on the cleaning box 11 .

[0034] As an optional implementation scheme of the present invention, since there may be stubborn stains such as oil stains on the plastic pallet, the effect of cleaning the plastic pallet by using the ultrasonic module 12 is more obvious.

[0035] like Figure 2-3 As shown, the device further includes a dosing unit 5 , which is connected to the cleaning box 11 via a dosing pipe 51 .

[0036] As an optional implementation scheme of the present invention, the dosing unit 5 mainly adopts a dosing pump or a metering pump, which can put cleaning agent into the cleaning box 11, and cooperate with the operation of the ultrasonic module 12 to greatly improve the cleaning effect of the plastic pallet.

[0037] like Figure 1 and 3 As shown, it also includes a spray pipe 6 arranged in the cleaning box 11 and a plurality of spray heads 7 connected to the spray pipe 6. The spray pipe 6 is connected to the water inlet 13 through-connected.

[0038] As an optional embodiment of the present invention, the pallet in the cleaning box 11 can also be cleaned by flushing, and the external water source enters the spray pipe 6 so that the spray head 7 flushes the plastic pallet. On this basis, those skilled in the art can further improve the distribution of the spray head 7, for example, the spray head 7 is aimed at the pallet at different angles to achieve full-scale flushing of the pallet, and the dosing pipe 51 of the dosing unit can also be connected to the spray pipe 6 through a three-way valve.

[0039] like Figure 1-2 As shown, the electromagnetic valve 8 is also included, which is respectively arranged at the water inlet 13 and the water outlet 14.

[0040] As an optional implementation scheme of the utility model, no matter whether the method of immersion cleaning or flushing is adopted, the water inlet 13 and the water outlet 14 need to be controlled to avoid wasting water resources.

[0041] like Figure 1-2 As shown, the conveyor line 2 includes a bracket 21, a support component 22 rotatably connected to the bracket 21, and a power module 23 for driving the support component 22 to rotate. The support component 22 includes but is not limited to a conveyor belt, a roller, and a conveyor chain.

[0042] As an optional implementation scheme of the utility model, the power module 23 mainly includes a stepper motor or a servo motor, which is used to drive the operation of the conveyor belt, roller or conveyor chain; when the pallet is driven by the conveyor line 2 to a position suitable for the robot 3 to pick up, the conveyor line 2 can be stopped by the command set by the controller, and the next pallet will be transported to the position suitable for the robot 3 to take away the pallet after the robot 3 takes away the pallet.

[0043] like Figure 2 As shown, it also includes a control unit 9, which is electrically connected to the manipulator 3, the electromagnet 4, the cleaning unit 1 and the conveying line 2 respectively.

[0044] As an optional implementation scheme of the utility model, the control unit 9 can realize fully automatic operation of the technical solution, so that the entire tray cleaning process does not require human intervention, which greatly saves manpower and energy consumption.

[0045] The working principle and use process of the utility model are as follows: when the immersion method is adopted, the water inlet 13 in the cleaning box 11 is opened and the water outlet 14 is closed, the dosing unit 5 is turned on and the cleaning agent is put into the cleaning box 11, and when the conveyor line 2 drives the tray to a position suitable for the manipulator 3 to take the tray away, the manipulator 3 drives the electromagnet 4 to move to the steel beam aligned with the tray, and after turning on the electromagnet 4, the tray is sucked by the manipulator 3, and the manipulator 3 can drive the tray into the cleaning box 11, and then the ultrasonic module 12 can be turned on for cleaning. After cleaning, the manipulator 3 takes out the tray and puts it back into the conveyor line 2. When the water in the cleaning box 11 can no longer be used for cleaning, the electromagnetic valve 8 of the water outlet 14 is opened to discharge the sewage;

[0046] When the flushing method is adopted, the manipulator 3 drives the pallet into the cleaning box 11, the water inlet 13 is opened, and the water source and the cleaning agent enter the spray pipe 6 together to directly flush the pallet in all directions. The flushed pallet can be placed back on the conveyor line 2 by the manipulator 3.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
