Description

Technical Field

[0001] This utility model relates to water quality testing equipment, and more specifically, to an automatic transfer device for wastewater testing. Background Technology

[0002] With increasing emphasis on environmental protection, accurate and real-time water quality testing is crucial for maintaining aquatic ecological security and protecting human health. Typically, wastewater testing involves analyzing key indicators such as total phosphorus, total nitrogen, pH, and COD to comprehensively assess water quality.

[0003] When testing water quality, wastewater (the water to be tested) samples are usually sent for testing separately, and operators perform the testing procedures according to the testing standards. Common testing processes typically follow established standards and have fixed procedures.

[0004] To improve testing efficiency, some institutions have begun experimenting with robotic arms to manipulate sample tubes and other components, partially replacing manual inspection. Furthermore, to achieve streamlined water quality testing, conveyor lines can be used to transport wastewater samples between various testing stations, enabling automated testing. However, because the robotic arms handling the samples typically operate according to pre-programmed procedures, the sample tubes cannot be accurately positioned during transport on the conveyor belt, potentially leading to misalignment. This results in the robotic arms being unable to reliably and stably clamp the samples, affecting the continuity of the testing operation.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic wastewater detection device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An automated wastewater testing device includes a conveyor line for transporting sample racks. The conveyor line has several operating stations, and a positioning mechanism is provided at each operating station. The positioning mechanism includes a first telescopic rod and a second telescopic rod, which are located on opposite sides of the conveyor line and each has a telescopic end. A positioning plate is fixedly installed at the telescopic end of the first telescopic rod and a positioning plate is fixedly installed at the telescopic end of the second telescopic rod. The positioning plates are respectively fitted against the sides of the sample rack for positioning the sample rack.

[0009] The present invention is further configured such that the two sides of the sample rack are respectively positioning part one and positioning part two, positioning plate one and positioning part one are mutually abutting and adapted, and positioning plate two and positioning part two are mutually abutting and adapted.

[0010] The present invention is further configured such that the opposite sides of the positioning part and the positioning plate form a plane, and positioning is achieved by the planes abutting each other.

[0011] The present invention is further configured such that two inclined positioning slopes are formed on both sides of the positioning part two, a positioning groove is formed on the side of the positioning plate two facing the positioning part two, and the positioning slopes are formed on both sides of the positioning groove. Part of the positioning part two can be embedded in the positioning groove, and the positioning slopes one and two mutually press and limit each other.

[0012] The present invention is further configured such that side baffles are fixedly connected to both sides of the conveyor line, and a conveying path is formed between the side baffles; the first telescopic rod and the second telescopic rod are respectively installed on the side baffles on both sides.

[0013] The present invention is further configured such that an upper guide plate is fixedly connected to one side of the two side baffles opposite to each other, and the upper guide plate and the positioning plate one and the positioning plate two are respectively provided with notches, and the positioning plate one and the positioning plate two can be retracted into the corresponding notches.

[0014] The present invention is further configured such that the sample rack has several holes on its upper side for vertically placing sample tubes.

[0015] The present invention is further configured such that the positioning part has a blind hole, the blind hole is open on the side facing the positioning plate, a ball is installed in the blind hole, and a spring is elastically pressed on the side of the ball facing away from the positioning plate; part of the ball can protrude from the surface of the positioning part and can roll relative to the surface of the positioning plate.

[0016] The present invention is further configured such that a retaining ring is installed at the opening of the blind hole, the retaining ring being used to block and restrict the ball within the blind hole; the retaining ring is flush with the surface of the positioning part.

[0018] In summary, this utility model has the following beneficial effects:

[0019] Using a sample rack to load sample tubes can maintain the stability of the sample tube loading. The sample rack can also be used to position the sample tubes. Once the sample rack is positioned, it can be ensured that the sample tubes are also in the correct position.

[0020] By using positioning plates on both sides to clamp and position the positioning parts on both sides of the sample rack, the telescopic rods on both sides push the positioning plates to extend and clamp the sample rack when in the positioning state. This effectively limits the position of the sample rack and ensures the stability of the position of the sample rack and sample tubes, making it easier for the robot to operate the sample tubes.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This embodiment discloses an automated wastewater testing device, including a conveyor line 1. The conveyor line 1 transports sample racks 2, which are loaded with sample tubes 21 to be tested. Along the conveying path 10 of the conveyor line 1, there are several operating stations 101. A robotic arm 3 is installed on the outer side of each operating station 101, which can perform testing actions on the sample tubes 21, thereby realizing the corresponding testing action at the corresponding operating station 101.

[0030] To place sample tubes 21 within the sample rack 2, several holes, typically three, can be made on the upper side of the sample rack 2, allowing three sets of sample tubes 21 to be placed vertically. The sample rack 2 supports and limits the sample tubes 21, enabling them to be placed and positioned. Once the sample rack 2 is positioned, it ensures that the sample tubes 21 are also in the correct position.

[0031] The conveyor line 1 can be a conveyor belt or other conveying structure, as long as it can convey the sample rack 2. Side baffles 11 are fixed on both sides of the conveyor line 1 to limit the conveyed sample rack 2. A conveying path 10 is formed between the two side baffles 11. The sample rack 2 flows and is conveyed along the conveying path 10, from the previous operating station 101 to the next operating station 101.

[0032] A positioning mechanism is provided at the operating station 101 of the conveyor line 1. The positioning mechanism can position the sample rack 2 so that the sample rack 2 can be accurately positioned at the corresponding operating station 101, which makes it easier for the robot arm 3 to pick up the sample tube 21 or add reagents to the sample tube 21 more accurately and smoothly.

[0033] Reference Figures 2-5 As shown, the positioning mechanism includes a telescopic rod 4 and a telescopic rod 5. The telescopic rod 4 and the telescopic rod 5 are located on both sides of the conveyor line 1. The telescopic rod 4 and the telescopic rod 5 each have a telescopic end. The telescopic end of the telescopic rod 4 is fixedly installed with a positioning plate 41, and the telescopic end of the telescopic rod 5 is fixedly installed with a positioning plate 51.

[0034] Positioning plate 41 and positioning plate 51 cooperate to clamp both sides of the sample rack 2. Positioning plate 41 and positioning plate 51 respectively press and fit against both sides of the sample rack 2, thus positioning the sample rack 2. During the conveying process, the sample rack 2 is conveyed in the relatively wide conveyor line 1. When the sample rack 2 reaches the corresponding operating station 101, there may be a certain positional deviation. By clamping both sides of the sample rack 2 through the positioning mechanism, the position of the sample rack 2 can be aligned and positioned.

[0035] The sample holder 2 has a positioning part 22 and a positioning part 23 on each side, with the positioning parts 22 and 23 facing the side baffles 11 on both sides. Telescopic rods 4 and 5 are respectively installed on the side baffles 11 on both sides, so that positioning plate 41 faces positioning part 22, and positioning plate 51 faces positioning part 23. By extending and retracting the telescopic rods 4 and 5, positioning plate 41 and positioning part 22 can press against each other, and positioning plate 51 and positioning part 23 can press against each other, thus clamping and limiting the two sides of the sample holder 2.

[0036] Specifically, refer to Figure 4 As shown, the positioning part 22 and the positioning plate 41 form a plane on opposite sides. By abutting the planes, the sample holder 2 can be positioned by pressing against the positioning plate 41. After pressing, the position of the sample holder 2 can be kept roughly straight, and positioning can be achieved in the width direction of the conveyor line 1.

[0037] The second positioning part 23 has two inclined positioning ramps 231 on both sides, making the second positioning part 23 roughly form an isosceles trapezoidal shape. The second positioning plate 51 has a positioning groove 511 on the side facing the second positioning part 23, and the shape of the positioning groove 511 is adapted to the second positioning part 23. The second positioning ramps 512 are formed on both sides of the positioning groove 511, and the positioning groove 511 as a whole also forms an isosceles trapezoidal shape. The second positioning ramps 512 and the first positioning ramps 231 are mutually abutted and adapted.

[0038] When the positioning plate 2 51 and the positioning part 2 23 abut against each other, part of the positioning part 2 23 can be embedded into the positioning groove 511. The positioning inclined surface 2 512 and the positioning inclined surface 1 231 abut against each other. When the sample holder 2 has a displacement in the front-back direction, the positioning inclined surface 2 512 on the corresponding side can push the positioning inclined surface 1 231, thereby enabling the sample holder 2 to adjust its position in the front-back direction of the conveyor line 1.

[0039] Furthermore, an upper guide plate 12 is fixedly connected to one side of the two side baffles 11 opposite to each other. The upper guide plate 12 protrudes towards the middle of the conveyor line 1 to form a guiding structure for the sample holder 2.

[0040] Notch 121 is provided at positions corresponding to positioning plate 41 and positioning plate 51. When telescopic rod 4 and telescopic rod 5 retract, positioning plate 41 and positioning plate 51 can retract into the corresponding notch 121. In addition, several guide wheels (not shown in the figure) can be installed on the upper guide plate 12 to guide the sample holder 2 and improve the smoothness of the sample holder 2's operation.

[0041] After sample rack 2 arrives at operating station 101, conveyor line 1 stops running, allowing sample rack 2 to be positioned at the stopped operating station 101. Then, the telescopic end of telescopic rod 4 extends, causing positioning plate 41 to abut against positioning part 22 of sample rack 2. The telescopic end of telescopic rod 5 also extends, causing positioning plate 51 to abut against positioning part 23 of sample rack 2. Positioning plate 41 and positioning plate 51 form a limit on both sides of sample rack 2, forming a clamping state for sample rack 2. Positioning plate 41 and positioning part 22 interact with each other. The planar contact allows for positioning of the sample holder 2 in the width direction of the conveyor line 1. Simultaneously, after the positioning part 23 is embedded in the positioning groove 511, the positioning inclined surface 512 can block and limit the positioning inclined surface 231 of the positioning part 23. The mutual pressing force of the two inclined surfaces can push the sample holder 2 along the length direction of the conveyor line 1. With the support of the positioning plate 41, the sample holder 2 can be finely adjusted to ensure that it can be accurately positioned and ensure the positional accuracy of the sample holder 2 during operation.

[0042] To reduce the frictional resistance between the positioning part 22 and the positioning plate 41 of the sample holder 2, and to facilitate fine-tuning of the sample holder 2. (Refer to...) Figure 4 , Figure 6 As shown, the positioning part 22 has a blind hole 9, which is open towards the positioning plate 41. A ball bearing 6 is installed inside the blind hole 9, and a retaining ring 8 is installed at the opening of the blind hole 9. The retaining ring 8 can be glued or threaded, and is fixed at the opening of the blind hole 9. It can limit the ball bearing 6, blocking and restricting the ball bearing 6 inside the blind hole 9, so that only part of the ball bearing 6 can protrude.

[0043] A spring 7 elastically presses against the side of the ball bearing 6 facing away from the positioning plate 41. The spring 7 presses against the bottom of the blind hole 9 between itself and the ball bearing 6, applying an elastic force to the ball bearing 6 towards the positioning plate 41. Under the action of the spring 7, a portion of the ball bearing 6 can protrude from the surface of the positioning part 22 and roll against the surface of the positioning plate 41. Through the rolling friction between the ball bearing 6 and the positioning plate 41, the frictional resistance between the two can be reduced, facilitating a slight offset alignment of the sample holder 2 during clamping.

[0044] Furthermore, the retaining ring 8 is flush with the surface of the positioning part 22. After the positioning plate 41 is completely pressed against the positioning part 22, the positioning plate 41 can press the ball 6 into the blind hole 9. The planes of the positioning plate 41 and the positioning part 22 form mutual pressure, thereby enabling a stable pressure limit to be formed between the sample holder 2 and the positioning plate 41.

[0045] Furthermore, at the positioning part 22 of the sample holder 2, two or more sets of blind holes 9, springs 7 and balls 6 are generally provided in two sets. By setting them according to the above structure, multiple rolling support points can be formed to ensure that the sample holder 2 can be smoothly positioned when subjected to clamping and fine adjustment.

[0046] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
