Description

Technical Field

[0001] The present application belongs to the technical field of cleaning of test instruments, and in particular, relates to a cleaning device for test tubes. Background Art

[0002] Test tubes are commonly used instruments in biochemical experiments and often need to be used repeatedly. They need to be cleaned after each use to ensure that they are ready for the next use. A simple way to clean the test tube is to hold the test tube by hand, then use the water spray head to impact the inner wall of the test tube, continuously rinse and pour out the water. If necessary, it is necessary to use a brush to brush the inner wall of the test tube, and then continue to rinse to ensure the cleaning effect; in this case, if it is operated by hand, it is not convenient to switch between rinsing and brushing. There are also some assembly lines that can rinse, brush, and rinse test tubes placed in batches. On the one hand, this method has a large waste of resources when the number of test tubes to be cleaned is small. On the other hand, in order to simplify the equipment structure, the test tube is placed or clamped in an inverted state, and the flushing water is flushed from the bottom to the top. The flushed water will flow down to the nozzle and cause pollution to the nozzle. Utility Model Content

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0025] The present application embodiment provides a cleaning device, such as Figure 1-Figure 4 As shown, it includes a pneumatic clamp 1, a rotating mechanism 2, a vertical linear mechanism 3, a water spray head 5, an inclined collecting frame 6, a brush 7, etc.

[0026] The pneumatic clamp 1 is used to clamp the test tube to be cleaned; the rotation output end of the rotating mechanism 2 is connected to the pneumatic clamp 1 and is used to drive the pneumatic clamp 1 to rotate.

[0027] Specifically, Figure 2 The figure shows an optional implementation of a pneumatic clamp. The pneumatic clamp 1 includes a pair of arc-shaped clamps 11, a pair of moving rods 12 respectively connected to the arc-shaped clamps 11, and a double-headed cylinder 14 arranged in a frame 10. The moving rod 12 is slidably matched in the moving groove of the frame 10 and extends into the frame 10. The two movable ends of the double-headed cylinder 14 are respectively connected to a moving rod 12, and the rotating output end of the rotating mechanism 2 is connected to the frame 10. The movable end of the double-headed cylinder 14 moves, acting on the moving rod 12 to move along the moving groove, so that the arc-shaped clamp 11 can clamp and release the test tube. Specifically, the rotating mechanism 2 can be implemented by a rotating cylinder or a motor.

[0028] The movable end of the vertical linear mechanism 3 is connected to the rotating mechanism 2, and is used to drive the rotating mechanism 2 to rise and fall. Specifically, the vertical linear mechanism 3 can adopt a linear lead screw.

[0029] The water spray head 5 is horizontally arranged and connected to the water inlet pipe, the brush 7 is vertically arranged and arranged on a rotating assembly, and the rotating assembly can be realized by a motor. The overall length of the brush 7 is greater than the length of the test tube to ensure that it can contact and cover the inside of the test tube.

[0030] The specific positions of the water spray head 5 and the brush 7 are set to meet the following requirements: when the test tube is clamped in the pneumatic clamp 1 and is in a horizontal position and at a predetermined height, the mouth of the test tube faces the water spray head 5, and the test tube is coaxial with the water spray head 5. Figure 1 When the test tube is rotated to a vertical position, the mouth of the test tube faces the brush 7, and the test tube and the brush 7 are coaxial, as shown in FIG. Figure 4 As shown, it should be noted that Figure 4 At this time, the test tube has been lowered to the position where it cooperates with the brush 7 part as the vertical linear mechanism 3 raises and lowers the rotating mechanism 2.

[0031] The inclined collection frame 6 is arranged below the water spray head 5, and the upper end of the inclined collection frame 6 is located outside the rotation track of the test tube from the horizontal posture to the vertical posture to avoid interference with the test tube during rotation. Figure 3 In the posture shown, the downward projection of the test tube mouth is located within the collection range of the inclined collection frame 6. Specifically, as Figure 1 and3 As shown, the inclined collecting frame 6 can be used to collect the discharged water when the water is flushed and transfer the water to the test tube. Figure 3 When the device moves to the position shown and stays there for a short time, the water discharged by the collecting residue continues to be tilted so that the collected water is collected in a predetermined collection manner.

[0032] When in use, the test tube is clamped in the pneumatic clamp 1, and the test tube is placed in the following position by operating the rotating mechanism 2 and the vertical lifting mechanism 3. Figure 1 The test tube is flushed by water spraying head 5, and the flushing water is collected by the inclined collecting frame 6 below. After flushing for a certain period of time, the flushing is stopped, and the cylinder fixture 1 is rotated to the position as shown in FIG. Figure 3 The test tube is in the posture shown and stays for a short time. At this time, the residual water will continue to be discharged and collected by the inclined collection frame 6. Then the cylinder clamp 1 is rotated by the rotating mechanism 2 until the test tube is in a vertical posture. At this time, the rotating mechanism 2 and the pneumatic clamp 1 are lowered by the vertical linear mechanism to make the test tube fit into the brush, as shown in FIG. Figure 4 As shown, the inside of the test tube is scrubbed by continuously lifting and rotating the brush in coordination with the rotating assembly. After scrubbing, the cleaning can be completed directly, or the test tube can be rotated back to a horizontal position for another rinse.

[0033] As a preferred method of this example, Figure 5 As shown, the pneumatic clamp 1 also includes a wiping mechanism, and the vertical linear mechanism 3 is arranged on a rotating platform 4. The rotating platform 4 can be driven to rotate by an internally arranged motor, and the rotating platform 4 is used to drive the vertical linear mechanism 3 to rotate between the first position and the second position. The water spray head 5, the brush 7, and the inclined collection frame 6 are in the direction facing the pneumatic clamp 1 when the vertical linear mechanism 3 is in the first position, and the wiping mechanism is in the direction facing the pneumatic clamp 1 when the vertical linear mechanism 3 is in the second position.

[0034] The wiping mechanism includes a vertical rod 82 provided on the output shaft of the rotating motor 83 and a wiping cloth 81 sleeved on the vertical rod 82. Optionally, the wiping cloth 81 is fixed to the vertical rod 82 by a rope or a rubber band. When the vertical linear mechanism 3 is in the second position and the test tube is in a vertical posture, the mouth of the test tube faces the vertical rod 82, and the test tube is coaxial with the vertical rod 82. Specifically, the rotation angle of the vertical linear mechanism 3 between the first position and the second position can be 90°, and of course it can also be set to other rotation angles that do not affect the operation of the wiping mechanism.

[0035] When the vertical linear mechanism 3 is in the second position, the vertical linear mechanism 3 is continuously raised and lowered. Figure 5 As shown, in conjunction with the rotating motor 83, the inside of the test tube can be wiped to improve the cleanliness and provide a great preliminary effect for preliminary drying.

[0036] As a further preferred embodiment, there are multiple wiping mechanisms, which are arranged in a circular array on a turntable 84, and the turntable 84 can be driven by a power mechanism to rotate around its axis, so that when dealing with the cleaning of several test tubes, the turntable 84 can be rotated to switch the wiping mechanism, so that after all the test tubes to be cleaned are processed, the wiping cloth 81 can be replaced in batches, simplifying the operation and improving the efficiency. Of course, the batch cleaning quantity here is generally several or about 10, which is also the case where the number of test tubes is small for the device of this application.

[0037] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
