BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a schematic diagram of the structure of the present invention;

[0015] Figure 2 It is a schematic diagram of the cross-sectional structure of the present invention. DETAILED DESCRIPTION

[0016] As attached Figure 1 , 2 As shown, the present invention comprises a housing 1, a new brush bin 6, an old brush bin 7, a bracket 3, an old brush conveying device and a new brush conveying device. The housing 1 in this embodiment is square, and other shapes may also be used. An inclined plate 2 is provided at the entrance of the housing 1 to facilitate the entry of the sweeping robot.

[0017] The new brush bin 6 and the old brush bin 7 are located at the rear of the housing 1 and separated by a partition 10. Preferably, the new brush bin 6 is located above the old brush bin 7, and a new brush inlet 8 is provided at the top of the new brush bin 6 and a new brush outlet 12 is provided at the front side, and an old brush outlet 9 is provided at the rear side of the old brush bin 7 and an old brush inlet 13 is provided at the front side, which is more conducive to putting a new brush into the new brush bin 6 and also convenient for taking away the replaced old brush. In the housing 1, the space in front of the new brush bin 6 and the old brush bin 7 is the front bin, which is used to place the sweeping robot. The old brush conveying device removes the old brush on the sweeping robot and puts it into the old brush bin 9, and the new brush conveying device grabs the new brush in the new brush bin 6 and installs it on the sweeping robot.

[0018] Sensors can be added in the new brush bin 6 and the old brush bin 9 to monitor the number of brushes in the bins, and timely reminders can be given when there are fewer new brushes in the new brush bin 6 or more old brushes in the old brush bin 9.

[0019] Preferably, the old brush conveying device and the new brush conveying device have the same structure, which is more conducive to saving production costs.

[0020] The old brush conveying device includes a first conveyor belt 15 correspondingly arranged on the inner wall of the side plate of the shell 1 and a grasping device 5 fixed on the first conveyor belt 15. One end of the first conveyor belt 15 corresponds to the position of the old brush bin 7, and the other end corresponds to the brush installation position of the sweeping robot.

[0021] The new brush transport device includes a second conveyor belt 4 correspondingly arranged on the inner wall of the side plate of the shell 1 and a gripping device 5 fixed on the second conveyor belt 4. One end of the second conveyor belt 4 corresponds to the position of the new brush bin 6, and the other end corresponds to the brush installation position of the sweeping robot.

[0022] The new brush conveying device and the old brush conveying device are two workstations. The bracket 3 first lifts the sweeping robot to a certain height to a position corresponding to the old brush conveying device, removes the old brush, and then the bracket 3 continues to lift to a position corresponding to the new brush conveying device to install the new brush. The height difference between the new brush conveying device and the old brush conveying device can also be adjusted. When the robot is at a certain height, both the new and old brush conveying devices can work, and the work of removing the old brush and conveying the new brush can be carried out at the same time, which can greatly improve the efficiency of replacement.

[0023] The first conveyor belt 15 and the second conveyor belt 4 are both L-shaped rotated 90° counterclockwise, and the outer ends of their horizontal sections correspond to the old brush bin 7 and the new brush bin 6 respectively, and their vertical sections correspond to the positions of the brushes of the sweeping robots at the corresponding workstations.

[0024] The gripping device 5 is a cylinder or a manipulator. When it is a cylinder, pin holes matching the piston rod of the cylinder are required to be provided on both sides of the brush of the sweeping robot. The piston rod of the cylinder extends outward and is inserted into the pin holes on both sides of the brush, so that the brush moves together with the cylinder.

[0025] The first conveyor belt 15 and the second conveyor belt 4 are both driven by a plurality of conveyor wheels 11, wherein one of the conveyor wheels 11 is connected to a driving motor to provide a driving force for transportation, so that the grabbing device 5 can achieve reciprocating motion on the corresponding conveyor belt.

[0026] The bracket 3 is driven by the lifting device to achieve up and down movement. At present, in the mechanical field, lifting devices that can achieve up and down movement of the bracket 3 are very common. They are common knowledge for those skilled in the art and will not be described here. At the same time, in order to ensure that the sweeping robot does not deviate from the position on the bracket 3, a structure for increasing stability is correspondingly provided on the bracket 3.

[0027] The sweeping robot used in conjunction with the present invention also needs to be improved accordingly. While keeping other structures of the existing sweeping robot unchanged, the installation method of the brush is changed so that the brush is clamped on the main body of the sweeping robot, and a lower baffle that can be opened and closed is provided on the lower end surface of the shell of the sweeping robot. When the brush needs to be taken out or installed, the lower baffle is opened. The lower baffle can be opened by installing a shift fork at a corresponding position, which is also common knowledge for those skilled in the art.

[0028] When the present invention is in use, the sweeping robot enters the specified position of the front bin, and under the action of the lifting device, the sweeping robot is lifted to a certain height so that the brush of the sweeping robot corresponds to one end of the first conveyor belt 15 located in the front bin, and then the grasping device 5 moves to the position corresponding to the brush of the sweeping robot under the drive of the first conveyor belt 15, clamps the brush, and then the grasping device 5 moves downward to remove the brush, and continues to move the removed brush into the old brush bin 9 through the old brush entrance 13, and then the grasping device 5 is released, and the old brush falls into the old brush bin 7. Then the position of the sweeping robot continues to rise to a position corresponding to one end of the second conveyor belt 4 in the front bin. The grabbing device 5 on the second conveyor belt 4 grabs the new brush in the new brush bin 6 and moves the new brush through the new brush outlet 12 to the front bin corresponding to the brush installation position of the sweeping robot. The grabbing device 5 then moves upward to install the new brush on the sweeping robot. The bracket 3 falls and the sweeping robot is put down to complete the entire brush replacement work.

[0029] The present invention has a control panel to control various actions of the entire device, and can also be connected to WIFI to remotely operate and remotely monitor the entire device through an APP. It also has a charging interface for charging the cleaning robot, which automatically charges the cleaning robot. The charging interface can directly use the charging interface of the existing cleaning robot, and the cleaning robot can automatically find the interface and automatically charge.
