Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent cleaning robots, and in particular relates to a self-cleaning structure of a sticky roller used inside a robot. Background Art

[0002] At present, traditional smart cleaning robots mainly perform indoor cleaning tasks by vacuuming and sweeping. As users become more and more dependent on smart cleaning robots, the use of smart cleaning machines is becoming more and more frequent.

[0003] The interior of the intelligent cleaning robot is equipped with a dust-sticking structure with a cleaning function. Since the dust-sticking roller of the dust-sticking structure has a limited dust collection capacity, the sticking roller needs to be replaced after a large amount of dust has accumulated. In the case of frequent use, the replacement frequency is relatively increased, and the cleaning time is relatively extended. Therefore, in order to reduce the replacement frequency of consumables and allow the robot's dust-sticking cleaning function to be used for a longer period of time, a self-cleaning structure for the sticky roller inside the robot is designed to solve the above problem.

[0004] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the utility model and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because these solutions are described in the background technology section of the utility model. Utility Model Content

[0005] In order to overcome the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a self-cleaning structure of a sticky roller used in a robot.

[0006] In order to achieve the above purpose and other related purposes, the technical solution provided by the utility model is: a self-cleaning structure of a sticky roller inside a robot, comprising a paper roll unit and a swing arm unit;

[0007] The paper rolling unit comprises:

[0008] first mounting frame;

[0009] An exhibition board, wherein the exhibition board is vertically fixed on the first mounting frame;

[0010] A first rotating shaft, which is horizontally and rotatably disposed on the first mounting frame and is used for winding the upper end of the roll paper;

[0011] A second rotating shaft, which is horizontally rotatably disposed on the first mounting frame and is located below the first rotating shaft; and is used for winding the lower end of the roll paper;

[0012] The swing arm unit comprises:

[0013] A second mounting frame;

[0014] a transmission shaft, the transmission shaft being horizontally rotatably disposed on the second mounting frame;

[0015] A swing arm, one end of which is fixed on the transmission shaft;

[0016] The sticky roller is horizontally rotatably arranged on one side of the display board and is transmission-connected with the other end of the swing arm; when the swing arm rotates upward, the sticky roller is arranged to contact the display board.

[0017] In this solution, when the ground needs to be cleaned, the swing arm rotates to the set contact position with the ground. After touching the ground, the sticky roller starts to work to clean the dust on the ground in the clean room. When the sticky roller needs to be cleaned, the swing arm reciprocates and contacts the sticky paper on the display board of the paper roll unit to realize the self-cleaning function.

[0018] Furthermore, a static elimination rod is arranged above the display board, and the static elimination rod is arranged on the mounting frame. In this solution, the static elimination rod can eliminate static electricity generated during self-cleaning in a very short time, ensuring the safety of using the machine in a clean room.

[0019] Furthermore, the first rotating shaft is connected to the first motor in a transmission manner, and the first motor is fixed on the mounting frame; the second rotating shaft is connected to the second motor in a transmission manner, and the second motor is fixed on the mounting frame. In this solution, the upper end of the roll of paper is wound on the first rotating shaft, and the first motor controls the rotation of the first rotating shaft, thereby controlling the retraction and release of the upper end of the roll of paper; the lower end of the roll of paper is wound on the second rotating shaft, and the second motor controls the rotation of the second rotating shaft, thereby controlling the retraction and release of the lower end of the roll of paper. The two motors are independently controlled, and the retraction and release are free and easy to control.

[0020] Furthermore, the first rotating shaft and the first motor, and the second rotating shaft and the second motor are connected via a synchronous belt transmission. In this solution, the synchronous belt transmission is adopted, which has stable transmission, can absorb vibration, is easy to maintain, and has low noise.

[0021] Furthermore, a parallel fixing plate is provided on one side of the adhesive roller, a connecting piece is fixed at both ends of the fixing plate, and the two ends of the adhesive roller are rotatably connected to the two connecting pieces respectively. In this solution, the connecting piece and the adhesive roller are detachably connected, and the connection can be achieved through a quick-release structure, which is convenient for disassembly, assembly and replacement of the adhesive roller.

[0022] Furthermore, the swing arm is connected to a suspension plate, the suspension plate is arranged parallel to the fixed plate, and a spring is arranged between the suspension plate and the fixed plate. In this solution, the swing arm is connected to a suspension plate, and a spring is arranged between the suspension plate and the fixed plate, which can play a role of telescopic adjustment and buffering when swinging; when the swing arm is rotated to a set position in contact with the ground, the suspension structure can adapt to the uncertainty of the ground.

[0023] Furthermore, the spring is sleeved on the suspension shaft, one end of the suspension shaft is fixed on the fixed plate, the other end passes through the suspension plate and is provided with a limit end, and the suspension plate is arranged to move back and forth on the suspension shaft. In this solution, the spring is sleeved on the suspension shaft, which improves the stability of the swing, and the movement of the suspension plate on the suspension shaft ensures the telescopic adjustment of the structure during the swing. Among them, there are two suspension shafts and both are sleeved with springs to improve the stability of the structure.

[0024] Further, a linear bearing is arranged on the suspension shaft, and the linear bearing is fixed on the suspension plate. In this scheme, the linear bearing is arranged on the suspension shaft, which can improve the straightness of the suspension plate when it moves back and forth on the suspension shaft, and improve the movement accuracy.

[0025] Furthermore, two swing arms are provided and fixed at the two ends of the transmission shaft respectively. In this solution, two swing arms are used and arranged at the two ends of the transmission shaft, and the structure is more stable when swinging.

[0026] Further, the transmission shaft is connected to a servo motor, and the servo motor is fixed on the second mounting frame through a mounting plate. In this solution, the servo motor is used to better control the swing position.

[0027] Due to the application of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0028] The utility model discloses a sticky roller self-cleaning structure for the inside of the robot. When the floor needs to be cleaned, the swing arm rotates to a set position in contact with the floor. After touching the floor, the sticky roller starts to work to clean the floor dust in the clean room. When the sticky roller needs to be cleaned, the swing arm reciprocates to contact the sticky paper on the display board of the paper roll unit to realize the self-cleaning function. The self-cleaning structure can reduce the frequency of replacing cleaning consumables of the sticky robot in the clean room, so that the single cleaning area is larger and the cleaning time is longer.
