[0017] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but these preferred embodiments should not be used to limit the scope of protection of the present invention.

[0018] See Figure 1-5 The figure shows an automatic bottle body device according to the present invention, including: frame 1, water tank 2, transverse movement mechanism 3, bottle clamping mechanism 4, cleaning mechanism 5, and drive mechanism 6.

[0019] The water tank 2 is mounted on the horizontal mounting plate of the frame 1 via water tank brackets 21. There are four water tank brackets 21, located at the four corners of the water tank. The water tank 2 has a cleaning position and a bottle receiving position. Preferably, the water tank 2 is rectangular to facilitate the movement of the horizontal moving mechanism 3 between the cleaning position and the bottle receiving position, and to facilitate the setting of the cleaning mechanism 5 and the bottle clamping mechanism 4. Therefore, in this embodiment, the cleaning mechanism 5 is set in the cleaning position on the left side of the water tank 2; the bottle clamping mechanism 4 is set in the bottle receiving position on the right side. The horizontal moving mechanism 3 is located below the bottle clamping mechanism 4 to drive the bottle clamping mechanism 4 to move. The bottle clamping mechanism 4 is set on top of the horizontal moving mechanism 3. The bottle clamping mechanism 4 is used to receive and position the sample bottle; the horizontal moving mechanism 3 is used to send the sample bottle from the bottle receiving position on the right side to the cleaning position on the left side, and to move in the opposite direction.

[0020] The cleaning mechanism 5 includes a brush 51, a drive wheel 52, a spray pipe 53, and a drain pipe 54. The brush 51 is mounted on the bottom of the water tank 2 via a brush shaft. The drive wheel 52 is mounted adjacent to the brush 51 on the bottom of the water tank 2 via a drive shaft. The brush shaft and drive shaft are not shown in the figure, but it can be understood that they are rotatably mounted on the bottom of the water tank 2, with both ends extending upwards and downwards respectively. The upper extension is used to mount the brush 51 and the drive wheel 52, and the lower extension is used to connect the drive mechanism 6. When the sample bottle 100 is in the cleaning position, the outer edge of the drive wheel 52 contacts the outer periphery of the sample bottle 100 to drive the sample bottle to rotate. The brush 51 contacts the outer periphery of the bottle body and bottle mouth of the sample bottle 100 to clean the bottle body and bottle mouth. That is, the diameter of the brush 51 is larger at the bottle mouth than at the bottle body, so that both the bottle body and bottle mouth are cleaned. The spray pipe 53 is located above the sample bottle 100 in the cleaning position to spray water onto the bottle body. The drain pipe 54 is located at the bottom of the water tank 2 and extends downward. The drive mechanism 6 is located on the frame 1 and is used to drive the drive wheel 52 and the brush 51 to rotate in opposite directions.

[0021] It should be noted that the rotation direction of the brush 51 is opposite to that of the drive wheel 52. The drive wheel 52 drives the sample bottle 100 to rotate, and the rotation direction of the sample bottle 100 is opposite to that of the drive wheel 52. The rotation direction of the brush 51 is the same as that of the sample bottle 100. The brush 51 moves towards the sample bottle 100 at the point of contact, which can increase the friction and increase the linear velocity of their relative rotation, thereby improving the cleaning efficiency.

[0022] In this embodiment, the lateral movement mechanism 3 is a lateral movement cylinder 31. This embodiment uses a rodless cylinder. When the lateral movement cylinder 31 moves to the right to its final position, the bottle clamping mechanism 4 is in the bottle receiving position. When the lateral movement cylinder 31 moves to the left to its final position, the bottle clamping mechanism 4 is in the cleaning position. At this time, the outer wall of the sample bottle contacts the drive wheel 52 and the brush 51. That is, the positioning of the lateral movement cylinder 31 between the cleaning position and the bottle receiving position is limited by the left and right movement limits of the lateral movement cylinder 31, eliminating the need for limiting mechanisms or components, thus simplifying the equipment.

[0023] In this embodiment, the bottle clamping mechanism 4 includes two grippers 41, each gripper 41 having an arc-shaped outer edge 411 and a gripper base plate 412 located on the inner side of the arc-shaped outer edge. The two gripper base plates 412 are provided with several protruding positioning protrusions 413 for positioning the inner side of the bottle mouth. When the two grippers 41 are open, the positioning protrusions 413 are located at the same circumference position as the bottle mouth, facilitating positioning when the sample bottle is delivered by the robotic arm. Each outer edge 411 has at least two uprights 414; in this embodiment, there are two uprights 414 at both ends of each outer edge 411. Preferably, the uprights 414 on the two outer edges 411 are aligned along the centerline (with...). The four rollers 415 are symmetrically arranged along a centerline aligned with the transverse direction. The top of the upright 414 is equipped with rollers 415. When the grippers 41 are closed, the four rollers 415 are concentric with the outer circle of the sample bottle 100, with a gap of 1-2 mm between the rollers 415 and the sample bottle 100. This means the rollers 415 position the sample bottle but do not clamp it, allowing the bottle to rotate during cleaning. Essentially, the outer edge 411 and rollers 415 can surround a large semicircle of the right side of the sample bottle (the side furthest from the cleaning position), exposing the portion of the sample bottle facing the brush 51 and drive wheel 52. An opening / closing cylinder 42 is connected to the grippers 41 to drive the grippers 41 in an opening and closing motion. The opening / closing cylinder 42 is equipped with a waterproof cover 45 to prevent wastewater and residue from splashing, causing equipment malfunction and extending its service life.

[0024] There are at least three positioning protrusions 413, and in this embodiment there are six. They are preferably evenly distributed on the two gripper base plates 412 in the open state, on the same circumference as the bottle opening. When the two grippers 51 are open, it facilitates bottle placement and positioning. At this time, the positioning protrusions 413 provide positioning to ensure that the sample bottle 100 is aligned with the center position when placed on the gripper base plate 412, and the position is not easily moved due to the restriction of the positioning protrusions 413. When the opening and closing cylinder 42 drives the grippers 41 to close, the position is restricted by the rollers 415 on the upright 414. At the same time, the rollers 415 provide rolling support for the rotation of the sample bottle 100.

[0025] Furthermore, in this embodiment, a sensor bracket 43 is provided on the transverse cylinder 31, located behind the opening / closing cylinder 42. Two position sensors 44 are provided on the sensor bracket 43. The position sensors 44 are located adjacent to the opening / closing cylinder 42 to detect whether the gripper is in an open / closed state.

[0026] In this embodiment, the drive mechanism 6 includes: a drive motor 61 mounted on the horizontal mounting plate of the frame 1, and preferably disposed adjacent to the drive wheel 52 and brush 51 of the cleaning mechanism on the side of the water tank 2; a transmission mechanism 62 disposed between the output shaft of the drive motor 61, the lower section of the drive shaft of the drive wheel 52, and the lower section of the brush shaft of the brush 51, i.e., the lower ends of the drive shaft of the drive wheel 52 and the brush shaft of the brush 51 extend to the bottom of the water tank 2; the transmission mechanism 62 is disposed between the water tank 2 and the horizontal mounting plate of the frame 1, and is used to drive the drive wheel 52 and brush 51 to rotate. It is understood that the transmission mechanism 62 includes a belt drive mechanism and a gear drive mechanism. The belt drive mechanism is located between the output shaft of the drive motor 61 and the drive shaft of the drive wheel 52, and the gear drive mechanism is located between the drive shaft of the drive wheel 52 and the brush shaft of the brush 51. The drive wheel 52 and the brush 51 rotate in opposite directions, which in turn drives the sample bottle 100 to rotate in the opposite direction. The brush 51 and the sample bottle 100 rotate in the same direction, and their contact positions move towards each other, thereby increasing the tangential friction force acting on the bottle wall and improving the relative linear velocity between them, which is beneficial to improving the cleaning efficiency of the outer wall of the sample bottle.

[0027] In this embodiment, a protective cover 7 is provided outside the cleaning position to prevent water splashing. The protective cover 7 is fastened to the top of the water tank 2 by a buckle 71. The protective cover 7 has a bottle clamping mechanism 4 and an opening 73 for the sample bottle to enter the protective cover on the side facing the sample bottle receiving position. Soft waterproof material, such as soft silicone, is provided on both sides of the opening 73 to form water-blocking parts 72. The sample bottle can pass through the water-blocking parts 72 into the protective cover 7. The water-blocking parts 72 returning to their original position can prevent the splashing of cleaning wastewater and residue, thus preventing environmental pollution and ensuring personnel safety.

[0028] In this embodiment, a drying mechanism 8 is further provided on the side of the sample bottle located at the cleaning position. The drying mechanism includes a fixing frame 81 placed on at least one side of the cleaning mechanism 5. In this embodiment, it is installed on the side of the protective cover 7, but it can also be directly installed on the water tank. At least one air knife 82 is movably connected to the fixing frame 81 and can rotate to adjust the direction of the air outlet for drying the surface of the bottle. In this embodiment, four air knives 82 are provided on one side of the protective cover 7. The air outlet of the uppermost air knife is horizontally set to dry the bottom of the bottle, and the other three air knives are vertically set to dry the outer wall of the bottle. One air knife 82 is provided on the opposite side. This allows the sample bottle to dry quickly and increases the frequency of use.

[0029] In this embodiment, the drain pipe 54 is positioned directly below the sample bottle during the cleaning process, facilitating rapid discharge of wastewater. Furthermore, centralized wastewater collection facilitates subsequent treatment.

[0030] The above description is illustrative only and not restrictive. The present invention aims to provide an automatic bottle cleaning device. Those skilled in the art will understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the claims, such as changing the transmission mechanism, using gear transmission instead of belt transmission, or changing the shape of the water tank, but all of these will fall within the protection scope of the present invention.
