Description

Technical Field

[0001] This application relates to the field of laboratory testing equipment technology, specifically to a temporary storage device. Background Technology

[0002] Existing laboratory testing equipment requires the use of TIP tips (pipette tips) during sample culture. To improve transfer efficiency, the TIPs are housed within a TIP tip holder. The existing patent CN218811659U protects a TIP head frame clamping device, which includes a TIP head box, a TIP head frame base, a TIP head frame, a spring clip mounting base, and a spring clip. The spring clip mounting base has a guide groove and a snap-fit ​​groove. The guide groove is used for the spring clip to pass through, and the snap-fit ​​groove is used to snap the spring clip mounting base onto the TIP head frame base. The spring clip includes a top section, an upper section, and a lower section. The lower section is fixedly installed on the spring clip mounting base. The upper section passes through the mounting groove of the TIP head frame base, and the top section extends into the guide groove of the spring clip mounting base. The upper section includes a first fold, a second fold, and a third fold. The angle between the first fold and the top section is 90 degrees, the angle between the second fold and the first fold is 125 degrees, the angle between the third fold and the second fold is 95 degrees, and the angle between the lower section and the third fold is 150 degrees. The existing TIP headstock clamping device can prevent operators from being scratched by the spring clips during the placement and removal of the TIP headstock; the bending angle of the spring clips is appropriate, which facilitates the installation and removal of the TIP headstock, and can accurately position and clamp the TIP headstock.

[0003] While existing TIP headstock clamping devices can ensure precise positioning of the TIP headstock, they can only restrict its position and cannot accurately measure whether the clamping device is holding the TIP headstock. If it is necessary to monitor whether the clamping device is loaded with a TIP headstock, additional monitoring equipment is required, which will increase the size of the entire device and easily cause interference problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0005] This application provides a temporary storage device, comprising:

[0006] The housing has a cavity for accommodating the front end of the suction head on the tray; a protective skirt is provided on the inner wall of the cavity, and a first region is formed between the protective skirt and the inner wall;

[0007] The detector is located in the first region and outside the projection range of the suction head along the Y-axis direction. The detector corresponds to the front end of the suction head.

[0008] In one embodiment, a positioning module is also included, which is disposed on the protective skirt.

[0009] In one embodiment, the positioning module comprises at least two elastic positioning heads, which are respectively mounted on two adjacent convex surfaces of the protective skirt.

[0010] In one embodiment, the number of elastic positioning heads is three.

[0011] In one embodiment, the detector is located below the protective skirt, which is provided with a corresponding elastic positioning head.

[0012] In one embodiment, a fixing platform is also provided on the inner wall, the fixing platform is located in the first area, and the detector is mounted on the fixing platform.

[0013] In one embodiment, the top surface is provided with feet for contacting the tray.

[0014] In one embodiment, the legs are L-shaped.

[0015] In one embodiment, the outer side of the support leg is flush with the outer surface of the housing.

[0016] In one embodiment, a clearance gap is formed between two adjacent legs.

[0017] This application has at least the following beneficial effects:

[0018] In this application, the material tray is mounted on a housing. A detector installed inside the housing detects whether the material tray is properly installed and whether the suction head is partially accommodated in the cavity. To avoid interference between the tip of the suction head and the detector, the detector is located in a stepped first area formed between the protective skirt and the inner wall. The protective skirt shields the detector, and the suction head is located within the area surrounded by the protective skirt, thus separating the detector from the tip of the suction head. Because the detector is located inside the housing, the empty area of ​​the cavity is used to house the detector, increasing the detection function of the material tray without increasing the volume, resulting in a more compact structure.

[0032] The embodiments of this application are described in detail below with reference to the accompanying drawings.

[0033] Reference Figure 1-4 As shown, some embodiments of this application provide a temporary storage device, including a housing 1. The housing 1 is provided with a positioning module for limiting the position of a tray 2. The tray 2 is loaded with multiple suction heads. After the tray 2 is supported on the housing 1, the positioning module fixes the tray 2, connecting the tray 2 and the housing 1 together. The housing 1 has a cavity 12 extending to the top surface 11 of the housing 1 to form an opening. The tray 2 rests on the housing 1 near the top surface 11, i.e., the tray 2 and the housing 1 are arranged vertically, and the weight of the tray 2 stabilizes its position on the housing 1. A detector 15 is installed on the inner wall of the cavity 12, and the detector 15 is positioned near the opening so that it corresponds to the front end of the suction head on the tray 2. Specifically, the detector 15 is located outside the front end of the suction head, with its detection end facing the front end of the suction head and a short detection distance. In one specific embodiment, the detection path of the detector 15 is perpendicular to the axis of the suction head. Detector 15 is used to detect the tray 2. In this embodiment, detector 15 is positioned close to the opening, making it easier for detector 15 to detect the portion of tray 2 extending into cavity 12 from the opening. More specifically, when tray 2 is supported on housing 1, the tip of suction head is located within cavity 12. Detector 15 determines whether housing 1 is supporting tray 2 by detecting the tip of suction head.

[0034] It is understood that the detector 15 is set at the front end of the suction head on the tray 2. Specifically, the detector 15 is located outside the front end of the suction head, and the detection end of the detector 15 faces the front end of the suction head. In a specific embodiment, the detection path of the detector 15 is set perpendicular to the axis of the suction head, and the detector 15 is also located within the projection range of the front part of the suction head along the X-axis direction, so that the detection distance of the detector 15 is short and the detection accuracy is higher.

[0035] In this design, a positioning module fixes and restricts the position of the tray 2, allowing the sampling mechanism to extract the suction tip from the tray 2 based on its fixed position. Simultaneously, a detector 15 detects whether the housing 1 contains the tray 2. First, the tip of the suction tip passes through the opening and is housed within the cavity 12. The housing 1 shields the tip, preventing it from being touched and detaching from the tray 2, thus ensuring the experiment proceeds normally. Second, the detector 15 is located within the cavity 12, utilizing the empty space within the housing 1 to house it. This adds the tray 2 positioning detection function to the temporary storage device without increasing its space. If the tray 2 is unloaded during transfer, the detector 15 can detect the fault and promptly issue an alarm and / or correct the error. An unloaded tray 2 specifically means that no tray 2 is fed into the temporary storage device at the loading end, but other equipment continues to operate normally. Error correction can be performed by replenishing the material tray 2 at the feeding end or skipping the empty cycle (in the case of an empty cycle, the process for the material tray 2 of the temporary storage device is paused, such as the process of the sampling mechanism extracting the suction head from the material tray 2).

[0036] Compared to adding an additional detection device outside the temporary storage device, the sampling mechanism outside the material tray 2 operates the suction head on the tray 2, which can easily cause interference between the sampling mechanism and the detection device. Furthermore, adding an additional detection device outside the temporary storage device requires reserving space for the detection device, increasing the space occupied by both the temporary storage device and the detection device. In this solution, the function of detecting the material tray 2 is integrated into the temporary storage device. This increases the functionality of the device without increasing the size of the entire device, resulting in a more compact layout that facilitates seamless integration and collaborative operation.

[0037] Furthermore, a protective skirt 14 is provided around one end of the cavity 12 near the top surface 11, and an opening is formed within the protective skirt 14. A first region a is formed between the protective skirt 14 and the inner wall, and the protective skirt 14 and the inner wall form a stepped structure, wherein the first region a is an L-shaped concave space. The detector 15 is located within the first region a, more specifically, the detector 15 is located below the protective skirt 14. For example, the outline shape of the cavity 12 is rectangular, the outline shape of the opening is concentrically arranged with the outline shape of the cavity 12, and the outline area of ​​the opening is smaller than the outline area of ​​the cavity 12. The detector 15 is positioned near the opening, specifically, the detector 15 is located at the bottom of the protective skirt 14.

[0038] In this embodiment, the positioning module comprises at least two elastic positioning heads 13, which are respectively mounted on two adjacent convex surfaces of the protective skirt 14. The protective skirt 14 has two adjacent first convex surfaces 141 and second convex surfaces 142, and at least two elastic positioning heads 13 are respectively disposed on the first convex surfaces 141 and second convex surfaces 142. Preferably, the number of elastic positioning heads 13 is three. One elastic positioning head 13 is mounted on the first convex surface 141, and the other two elastic positioning heads 13 are mounted on the second convex surface 142. In this embodiment, the elastic positioning heads 13 on the first convex surface 141 and the second convex surface 142 push against the tray 2, causing the tray 2 to abut against the other two convex surfaces of the protective skirt 14. The elastic positioning heads 13 and the protective skirt 14 clamp the tray 2 to fix its position. In addition, in this embodiment, three elastic positioning heads 13 are used to abut against the tray 2 to stably press the tray 2 onto the other two convex surfaces of the protective skirt 14. Preferably, the detector 15 is located below the protective skirt 14 on the side with two elastic positioning heads 13. The two elastic positioning heads 13 push the material tray 2, increasing the pushing force on the material tray 2 on the second convex surface 142, so as to ensure that the material tray 2 is far away from the second convex surface 142, that is, to ensure the distance between the detector 15 and the part of the material tray 2 that extends into the cavity 12, and reduce the risk of collision between the material tray 2 and the detector 15.

[0039] More specifically, the end of the elastic positioning head 13 that contacts the tray 2 is a ball head or an arc head. This increases the pressure exerted by the elastic positioning head 13 on the tray 2 while also facilitating elastic avoidance of the elastic positioning head 13 during tray 2 loading. It should also be noted that the elastic positioning head 13 can be inherently elastic, generating pressure on the tray 2 through its own elastic deformation, such as a sheet metal spring. Alternatively, the elastic positioning head 13 can include a rigid contact head (i.e., the structure in contact with the tray 2) and an elastic block. During tray 2 loading, the rigid contact head forces the elastic block to deform elastically, thereby causing the elastic positioning head 13 to generate pressure on the tray 2, such as a ball-head plunger.

[0040] Furthermore, the detector 15 is located outside the projection range of the suction head along the Y-axis. Since the tip of the suction head passes through the opening formed by the protective skirt 14, it can be known that the detector 15 is actually located within the projection range of the protective skirt 14 along the Y-axis. Specifically, the detector 15 is located within the orthogonal projection range of the protective skirt 14. During the process of loading the tray 2 into the housing 1, because the detector 15 is shielded by the protective skirt 14, the suction head and the tray 2 have difficulty contacting the detector 15, thereby improving the service life of the detector 15.

[0041] Preferably, the detector 15 is located below the protective skirt 14, which is equipped with the elastic positioning head 13. That is, the detector 15 is located below the corresponding portion of the first convex surface 141 or the second convex surface 142 on the protective skirt 14. The elastic positioning head 13 will push the tray 2 to press against the other two convex surfaces of the protective skirt 14, so that the detector 15 is away from the tray 2, making it less likely that the suction head and / or the tray 2 will come into contact with the detector 15.

[0042] In this design, a fixed platform 17 is provided on the inner wall of the cavity 12. The fixed platform 17 is located within the first region a, and the detector 15 is mounted on the fixed platform 17. Specifically, a space for accommodating the detector 15 is formed between the fixed platform 17 and the protective skirt 14. The detector 15 is placed on the fixed platform 17 to restrict the position of the detector 15.

[0043] In some embodiments of this application, the top surface 11 is provided with support legs 16 for contacting the tray 2. There are at least three support legs 16, arranged circumferentially on the outside of the opening. When the tray 2 is placed on the housing 1, the tray 2 is pressed against the support legs 16. The support legs 16 are used to support the tray 2 on the housing 1. Alignment notches are formed between adjacent support legs 16 to allow the tray 2 to be placed on the housing 1. Specifically, the tray 2 has a raised structure at its bottom; when the tray 2 is placed on the housing 1, the raised structure at the bottom of the tray 2 is located within the alignment notches between adjacent support legs 16. At the same time, the alignment notches between two adjacent support legs 16 provide gripping space for the gripping mechanism, facilitating the gripping mechanism to grasp the tray 2.

[0044] In this design, the support legs 16 are L-shaped. The outer contour of the housing 1 is rectangular. Preferably, there are four support legs 16, positioned at the four right angles of the top surface 11. The four support legs 16 support the material tray 2 at its four inner corners, stably supporting the material tray 2 on the support legs 16. It is understood that the shape of the support legs 16 includes, but is not limited to, L-shape; the shape of the support legs 16 can also be arc-shaped, I-shaped, or other common support structure shapes. In this design, multiple L-shaped support legs 16 of the same shape are used to support the material tray 2 in a coordinated manner; alternatively, support legs 16 of different shapes can be used to support the same material tray 2.

[0045] Furthermore, the outer side of the support leg 16 is flush with the outer surface of the housing 1. Specifically, the outer side of the support leg 16 is the side furthest from the open side. The outer surface of the housing 1 is specifically the outer contour side of the housing 1. In this design, the support leg 16 and the main body of the housing 1 are integrally formed to improve the overall integrity of the temporary storage device, resulting in a smoother and more aesthetically pleasing appearance. Simultaneously, the strength between the integral support leg 16 and the main body of the housing 1 is greater, thus extending the user experience.

[0046] The above embodiments are used to further illustrate this application, but do not limit this application to these specific implementations. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be understood as falling within the protection scope of this application.
