Detailed Description of the Embodiments

[0023] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0024] When cleaning utensils, generally four steps are involved: opening the lid, displacement, adding liquid, and cleaning. Currently, the entire process of opening the lid, displacement, adding liquid, and cleaning requires the support of a robotic arm. The specific process is as follows: Remove the cup lid of the beaker, place the cup lid in the designated area, pick up the beaker from the beaker placement area, transfer the beaker to the cleaning liquid outlet pipe and wait for the liquid to come out. After cleaning, transfer it to the detection instrument for the detection task. After the detection is completed, then put the beaker back into the beaker placement area, pick up the cup lid and put it back on the beaker. Thus, each set of process actions includes eight steps, the entire process is lengthy, the efficiency is low, and the loss of the robotic arm is relatively high.

[0025] Such as Figure 1 、 Figure 2 and Figure 3As shown, the utensil cleaning device of the embodiment of the utility model comprises: a frame 1, a driving member 2, a cleaning assembly 3, a first supporting plate 4 and a second supporting plate 5.

[0026] The first support plate 4 and the second support plate 5 are stacked on the frame 1 along the height direction of the frame 1, and the first support plate 4 is located below the second support plate 5. The first support plate 4 is configured to be suitable for fixing the cup body 61, and the second support plate 5 is configured to be suitable for fixing the cup cover 62; the cleaning component 3 is configured to provide cleaning liquid to the cup body 61; at least one of the first support plate 4 and the second support plate 5 is connected to the driving member 2, and under the drive of the driving member 2, the distance between the first support plate 4 and the second support plate 5 changes, so that the cup cover 62 is covered or separated from the cup body 61.

[0027] The frame 1 serves as the basis of the entire dishwashing device, supporting and fixing all other components, including the driving member 2, the cleaning assembly 3, the first support plate 4 and the second support plate 5. Exemplarily, the frame 1 includes a base 11 and a bracket 12 disposed on the base 11, and the bracket 12 may be a plate-shaped structural member or a rod-shaped structural member, etc., which is not specifically limited here.

[0028] It is particularly important to point out that the first support plate 4 can be slidably connected to the bracket 12, the second support plate 5 is fixedly connected to the bracket 12, and the driving member 2 is transmission-connected to the first support plate 4. In this way, under the drive of the driving member 2, the first support plate 4 approaches or moves away from the second support plate 5.

[0029] Alternatively, the second support plate 5 can be slidably connected to the bracket 12, the first support plate 4 is fixedly connected to the bracket 12, and the driving member 2 is transmission-connected to the second support plate 5, so that under the drive of the driving member 2, the second support plate 5 approaches or moves away from the first support plate 4.

[0030] Alternatively, the first support plate 4 is slidably connected to the bracket 12, the second support plate 5 is slidably connected to the bracket 12, and the driving member 2 is transmission-connected to the first support plate 4 and the second support plate 5. In this way, under the drive of the driving member 2, the first support plate 4 and the second support plate 5 move toward or away from each other.

[0031] Exemplarily, the first support plate 4 can be slidably connected to the bracket 12, the second support plate 5 is fixedly connected to the bracket 12, and in the case where the driving member 2 is drivingly connected to the first support plate 4, the cup body 61 is detachably disposed on the top surface of the first support plate 4, and the cup cover 62 is detachably disposed on the bottom surface of the first support plate 4. For example, a receiving groove is provided on the top surface of the first support plate 4, the cup body 61 is disposed in the receiving groove, and the cup cover 62 is disposed on the bottom surface of the first support plate 4 through a magnetic attraction assembly. Under the drive of the driving member 2, the first support plate 4 approaches or moves away from the second support plate 5 so that the cup cover 62 and the cup body 61 are covered or separated. In the initial state, the cup cover 62 and the cup body 61 are covered, and at this time, the cup cover 62 and the cup body 61 are in a sealed state. Under the drive of the driving member 2, the first support plate 4 moves away from the second support plate 5. During the downward movement of the cup body 61, the cleaning assembly 3 can provide cleaning liquid for the cup body 61. After the detection is completed, under the drive of the driving member 2, the first support plate 4 approaches the second support plate 5 so that the cup cover 62 and the cup body 61 are covered.

[0032] It can be understood that the driving member 2 can be an electric push rod or a servo motor cooperating with a lead screw transmission mechanism to achieve precise control and high-efficiency power output. Among them, after receiving the control signal, the driving member 2 drives the first support plate 4 and the second support plate 5 to move relative to each other along the height direction of the frame body 1, thereby changing the distance between the two. In addition, both the first support plate 4 and the second support plate 5 can be made of lightweight but strong materials, such as aluminum alloy or reinforced plastic.

[0033] In the embodiment of the present utility model, in the initial state, the cup cover 62 and the cup body 61 are covered, and at this time, the cup cover 62 and the cup body 61 are sealed. Before the container 6 is used for the detection task, the cleaning assembly 3 provides cleaning liquid for the cup body 61 to complete the cleaning of the cup body 61. And, under the drive of the driving member 2, the distance between the first support plate 4 and the second support plate 5 becomes larger so that the cup cover 62 and the cup body 61 are separated, and the cup body 61 can be used for the detection task. After the cup body 61 completes the corresponding detection task, under the drive of the driving member 2, the cup cover 62 and the cup body 61 can be covered. The above-mentioned container cleaning device can replace the robotic arm to complete the operation process of opening the cover, moving the cover, adding liquid, and closing the cover, thereby effectively solving the problem of low working efficiency of the robotic arm. In addition, throughout the process, no manual operation is required, thus avoiding the situation where manual cleaning may cause damage to the human body.

[0034] In an alternative embodiment, such as Figure 1 、 Figure 2 and Figure 3As shown, the cleaning assembly 3 includes a liquid storage tank 31, a liquid infusion tube 33, and a pump body 32. The liquid infusion tube 33 is connected to the liquid storage tank 31, and the pump body 32 is disposed on the liquid infusion tube 33. The liquid infusion tube 33 is configured to transport the cleaning liquid in the liquid storage tank 31 to the cup body 61 under the drive of the pump body 32. Among them, the liquid infusion tube 33 can be a flexible tube, and a nozzle can be provided at the end of the liquid infusion tube 33.

[0035] It should be noted that the liquid storage tank 31 is a sealed container and can be made of corrosion-resistant materials (such as stainless steel, high-density polyethylene, etc.) to ensure that the cleaning liquid will not be contaminated or deteriorated during storage. A liquid filling port and a sealing cover are provided at the top of the liquid storage tank 31 for easy filling and replacement of the cleaning liquid. Under the drive of the pump body 32, the liquid infusion tube 33 is responsible for safely and efficiently transporting the cleaning liquid in the liquid storage tank 31 to the cup body 61 that needs to be cleaned. Among them, the pump body 32 is the power source in the entire cleaning assembly 3, and a corrosion-resistant, easy-to-maintain centrifugal pump, diaphragm pump, or peristaltic pump can be selected. The pump body 32 is installed on the liquid infusion tube 33 to form a closed liquid path system between the liquid storage tank 31 and the nozzle.

[0036] In an alternative embodiment, as Figure 1 , Figure 2 and Figure 3 shown, the second support plate 5 is provided with a first mounting hole, the cup cover 62 is provided with a second mounting hole, the liquid inlet end of the liquid infusion tube 33 is connected to the liquid storage tank 31, and the liquid outlet end of the liquid infusion tube 33 sequentially passes through the first mounting hole and the second mounting hole.

[0037] It should be noted that the cup cover 62 is disposed on the bottom surface of the second support plate 5, and the cup cover 62 is also provided with a second mounting hole corresponding to the first mounting hole. The position and size of the second mounting hole need to be precisely matched with the first mounting hole to ensure that the liquid infusion tube 33 can fit tightly and will not shake.

[0038] In this way, when the pump body 32 starts to work, the cleaning liquid in the liquid storage tank 31 is transported to the cup body 61 through the liquid infusion tube 33. Since the liquid infusion tube 33 directly passes through the second mounting hole on the cup cover 62, the cleaning liquid can be directly sprayed into the cup body 61 for cleaning. This method not only improves the cleaning efficiency but also reduces the waste of cleaning liquid and environmental pollution.

[0039] In an alternative embodiment, as Figure 1 , Figure 2 and Figure 3 shown, the liquid infusion tube 33 is disposed on the frame body 1, and the ware cleaning device further includes a support member 7. The support member 7 is disposed on the top surface of the second support plate 5 and is close to the first mounting hole, and the liquid infusion tube 33 is attached to the outer periphery of the support member 7. Among them, the outer periphery of the support member 7 can be arc-shaped.

[0040] Among them, the infusion tube 33 is stably arranged on the frame body 1, and the infusion tube 33 can be realized by a buckle or other fixing devices. These fixing devices can be installed along the edge or internal structure of the frame body 1 to ensure that the infusion tube 33 maintains a stable position and shape during the cleaning process.

[0041] In addition, the support member 7 is installed on the top surface of the second support plate 5 and is arranged close to the first mounting hole. In this way, it can be ensured that the infusion tube 33 can be effectively supported and fixed before passing through the first mounting hole, thereby avoiding excessive bending or stress during the mounting process.

[0042] In practical applications, through the support and fixing effect of the support member 7, the infusion tube 33 can maintain a stable shape and position, so as to ensure that the cleaning liquid can be accurately and efficiently sprayed into the interior of the cup body 61. At the same time, the support member 7 can also reduce the vibration and wear of the infusion tube 33 during the cleaning process to a certain extent and extend its service life.

[0043] In an alternative embodiment, such as Figure 1 、 Figure 2 and Figure 3 shown, the central axes of the first mounting hole and the second mounting hole are arranged to coincide.

[0044] It should be noted that the central axes of the first mounting hole and the second mounting hole are arranged to coincide, which means that the infusion tube 33 can maintain a straight state when passing through the first mounting hole and the second mounting hole and will not be bent or distorted due to the hole position deviation. In this way, the precise alignment of the first mounting hole and the second mounting hole ensures that the cleaning liquid can be smoothly and accurately transported from the liquid storage tank 31 to the interior of the cup body 61.

[0045] In addition, the coincidence of the central axes of the first mounting hole and the second mounting hole reduces the frictional resistance and flow resistance of the infusion tube 33 in the mounting hole, improving the transportation efficiency of the cleaning liquid. At the same time, it also reduces the risk of damage to the infusion tube 33 due to uneven force.

[0046] In addition, when the infusion tube 33 stably passes through the two coincident mounting holes, its overall structure is more stable and is not prone to shaking or displacement due to external forces. This helps to improve the stability and reliability of the entire utensil cleaning device.

[0047] In an alternative embodiment, such as Figure 1 、 Figure 2 and Figure 3 shown, the liquid storage tank 31 includes a box body and a cover body. The cover body and the box body cooperate to form an accommodation space for storing the cleaning liquid. The cover body is provided with an opening communicating with the accommodation space, and the infusion tube 33 passes through the opening to extend into the accommodation space.

[0048] Among them, the box body of the liquid storage tank 31 is a container with a certain volume for storing cleaning liquid. The box body can be made of materials resistant to corrosion and high pressure, such as stainless steel, plastic or glass, etc. The shape and size of the box body can be designed according to actual needs to meet the requirements of different cleaning tasks.

[0049] The cover body is an important part of the liquid storage tank 31. The cover body and the box body cooperate to form a closed accommodating space. An opening communicating with the accommodating space is also provided on the cover body so that the infusion tube 33 can pass through and extend into the accommodating space. The cover body is usually made of a material matching the box body and is tightly connected to the box body by means of threads, buckles or other sealing methods to ensure the tightness of the accommodating space. It should be particularly noted that the size and shape of the opening should match the outer diameter of the infusion tube 33, and a certain margin should be left for easy installation and disassembly. At the same time, sealing elements such as gaskets or O-rings can be provided around the opening to prevent the cleaning liquid from leaking from the gap between the opening and the infusion tube 33.

[0050] In an alternative embodiment, such as Figure 1 、 Figure 2 and Figure 3 shown, the edge of the opening is a flexible body. Among them, the cover body can be made of flexible materials.

[0051] Among them, the flexible body can select materials with certain elasticity, corrosion resistance and easy processing, such as silica gel, rubber or some soft plastics. The above materials can deform when subjected to external forces, thereby providing better tightness and reducing stress concentration. In this way, due to the elasticity of the edge of the opening, when the infusion tube 33 passes through the opening, it can fit tightly and effectively prevent the leakage of the cleaning liquid.

[0052] In an alternative embodiment, such as Figure 1 、 Figure 2 and Figure 3 shown, the first support plate 4 is slidably arranged on the frame body 1, the driving member 2 is connected to the first support plate 4, and under the drive of the driving member 2, the first support plate 4 approaches or moves away from the second support plate 5.

[0053] It should be noted that the first support plate 4 can be arranged on the bracket 12 through a sliding assembly. For example, the sliding assembly includes a linear guide rail and a sliding member in sliding fit. The linear guide rail is arranged on the bracket 12, and the sliding member is arranged on the first support plate 4. The sliding member can be a slider. In this way, it can be ensured that the first support plate 4 slides smoothly on the bracket 12. Among them, the driving member 2 can be an electric push rod. Exemplarily, the action end of the electric push rod is connected to the bottom surface of the first support plate 4.

[0054] In an alternative embodiment, such as Figure 1 、 Figure 2 and Figure 3As shown, the utensil cleaning device further includes a control main board 8. The driving member 2 and the cleaning component 3 are both electrically connected to the control main board 8. The control main board 8 is configured to control the actions of the driving member 2 and the cleaning component 3 according to instructions. Among them, the pump body 32 of the cleaning component 3 is electrically connected to the control main board 8.

[0055] It should be noted that the control main board 8 is responsible for receiving external instructions (such as instructions input by the user through the control panel or control signals from the upper computer), and controlling the actions of the driving member 2 and the pump body 32 according to the preset program logic. The control main board 8 uses a high-performance processor to ensure the rapid response of instructions and the efficient execution of complex control algorithms. The control main board 8 provides a variety of interfaces (such as serial ports, parallel ports, USB interfaces, etc.) for electrical connection and data communication with components such as the driving member 2 and the pump body 32.

[0056] Specifically, when the utensil cleaning device is not in use, the second support plate 5 is close to the first support plate 4, and the cup body 61 placed on the second support plate 5 is fitted with the cup cover 62 on the first support plate 4, being in a sealed state. After the previous process section completes the sample reception, the detection workstation issues an instruction through the PLC logic control unit, and the instruction is transmitted to the control main board 8. The control main board 8 controls the peristaltic pump to act. That is, after the peristaltic pump receives the instruction from the control main board 8, the peristaltic pump extracts the cleaning liquid from the liquid storage tank 31, and the cleaning liquid enters the cup body 61 through the infusion tube 33. When the conveying time reaches the preset value, the peristaltic pump stops working. Thereafter, the control main board 8 controls the driving member 2 to act, and the driving member 2 drives the first support plate 4 to descend to the target height. The control main board 8 sends a signal to the PLC logic control unit of the detection workstation, and the PLC logic control unit controls the robotic arm to act so that the robotic arm takes away the cup body 61. After the detection task of the cup body is completed, the PLC logic control unit controls the robotic arm to place the cup body 61 back on the first support plate 4. At the same time, the PLC logic control unit sends a signal to the control main board 8. After receiving the signal, the control main board 8 issues an instruction, and the driving member 2 drives the first support plate 4 to rise until the cup body 61 is covered with the cup cover 62.

[0057] It should be noted that the cleaning liquid can include water and alcohol. For example, directly use a mixture of water and alcohol for cleaning, or first use alcohol and then use water for cleaning. At this time, the number of liquid storage tanks 31 is two, and the two liquid storage tanks 31 are respectively used to store water and alcohol. At this time, the number of infusion tubes 33 is three, and the three infusion tubes 33 are connected through a switching valve. The number of pump bodies 32 is two. In this way, the separate transportation of water and alcohol can be achieved.

[0058] It should be particularly noted that after the cleaning liquid is injected into the cup body 61 and the first support plate 4 moves away from the second support plate 5, the cup body 61 can be grasped by the robotic arm, and then the remaining liquid in the cup body 61 can be poured out. Alternatively, the ware cleaning device further includes a drain pipe. The liquid inlet end of the drain pipe is connected to the infusion pipe 33 through a switching valve. And when the cup body 61 and the cup cover 62 are covered, the liquid outlet end of the infusion pipe 33 can be substantially in contact with the bottom wall of the cup body 61. Another pump body is provided on the drain pipe, so as to drain the remaining liquid in the cup body 61. Wherein, the liquid outlet end of the drain pipe can be directly connected to the waste discharge channel or to the waste liquid tank, which is not specifically limited herein.

[0059] In addition, an embodiment of the present invention further provides a chemical experiment assembly, including a ware 6 and the above-mentioned ware cleaning device; the ware 6 includes a cup body 61 and a cup cover 62. The cup body 61 is arranged on the first support plate 4, and the cup cover 62 is arranged on the second support plate 5.

[0060] Specifically, since the chemical experiment assembly includes the ware cleaning device as described above, and the specific structure of the ware cleaning device refers to the above-mentioned embodiment, the chemical experiment assembly shown in this embodiment includes all the technical solutions of the above-mentioned embodiment. Therefore, it has at least all the beneficial effects obtained by all the above-mentioned technical solutions, which will not be elaborated herein one by one.

[0061] It should be particularly noted that the number of wares 6 can be multiple. That is to say, the first support plate 4 can be provided with multiple cup bodies 61, for example, two cup bodies 61 arranged side by side. At this time, the second support plate 5 is provided with multiple cup covers 62, and the cup covers 62 are arranged in one-to-one correspondence with the cup bodies 61. Correspondingly, there are multiple sets of cleaning assemblies 3, and each ware 6 is provided with a set of cleaning assembly 3.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
