[0029] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0030] In the related art, clamps can only carry either flat-bottomed or round-bottomed vessels, and cannot accommodate both flat-bottomed and round-bottomed vessels. Transporting different types of vessels requires replacing different clamps or installing at least two conveying mechanisms equipped with different clamps, which makes the conveying mechanisms inconvenient and costly. To address or improve the problem in the related art where clamps can only carry either flat-bottomed or round-bottomed vessels, the present invention provides a clamp, a conveying mechanism, and a detection line.

[0031] The following combination Figures 1 to 2 , describing the clamp provided in an embodiment of the present utility model.

[0032] Specifically, the clamp 1 includes a main body 101 , a limiting portion 102 and a mounting portion 103 .

[0033] The main body 101 is used to cooperate with the driving device 3 so that the driving device 3 can drive the clamp 1 to move. The main body 101 is provided with a supporting surface 1011 for supporting a flat-bottomed vessel 2. For example, the flat-bottomed vessel 2 includes but is not limited to a flat dish.

[0034] The limiting portion 102 is connected to the main body 101 and protrudes from the supporting surface 1011. The limiting portion 102 is used to abut against the outer circumference of the flat-bottomed container 2 and limit the flat-bottomed container 2 in a direction parallel to the supporting surface 1011.

[0035] The mounting portion 103 is connected to the main body 101. A mounting hole 1031 is provided on the surface of the mounting portion 103 for receiving a round-bottomed vessel. For example, round-bottomed vessels include, but are not limited to, test tubes. Optionally, the mounting portion 103 protrudes from the support surface 1011, and the mounting hole 1031 is provided on the end surface of the mounting portion 103 that protrudes from the support surface 1011.

[0036] In this embodiment, the flat-bottomed vessel 2 can be supported by the supporting surface 1011 of the main body 101, and the limiting portion 102 connected to the main body 101 and protruding from the supporting surface 1011 can be abutted against the outer circumferential surface of the flat-bottomed vessel 2, thereby limiting the flat-bottomed vessel 2 in a direction parallel to the supporting surface 1011, that is, the limiting portion 102 and the supporting surface 1011 jointly define the position of the flat-bottomed vessel 2 on the clamp 1, thereby ensuring that the flat-bottomed vessel 2 has a determined position on the clamp 1 and the stability of the flat-bottomed vessel 2 on the clamp 1 during transportation.

[0037] By providing a mounting portion 103 on the main body 101, and providing a mounting hole 1031 on the mounting portion 103, a round-bottomed vessel can be placed into the mounting hole 1031, and the mounting hole 1031 limits the round-bottomed vessel, so that the round-bottomed vessel has a fixed position on the clamp 1 and ensures the stability of the round-bottomed vessel on the clamp 1 during transportation.

[0038] With such a configuration, the clamp 1 provided in the embodiment of the present invention can limit the flat-bottomed vessel 2 through the main body 101 and the limiting portion 102 so that the clamp 1 can adapt to the flat-bottomed vessel 2, and can limit the round-bottomed vessel through the mounting hole 1031 on the mounting portion 103 so that the clamp 1 can adapt to the round-bottomed vessel. Therefore, the clamp 1 provided by the present invention can adapt to both flat-bottomed vessels 2 and round-bottomed vessels.

[0039] refer to Figure 1 As shown, in some embodiments of the present invention, the mounting portion 103 is connected to the limiting portion 102. This arrangement connects the mounting portion 103, limiting portion 102, and main body 101 in pairs, enhancing the overall structural strength of the clamp 1. Furthermore, the mounting portion 103 and limiting portion 102 are connected without any gap between them, making the overall structure of the clamp 1 more compact and reducing the space occupied by the clamp 1.

[0040] refer to Figure 1 As shown, in some embodiments provided by the present invention, the mounting portion 103 and the limiting portion 102 are both used to abut against the outer circumferential surface of the flat-bottomed container 2 and jointly limit the flat-bottomed container 2 in a direction parallel to the supporting surface 1011. In this embodiment, by the mounting portion 103 and the limiting portion 102 jointly limiting the flat-bottomed container 2 in a direction parallel to the supporting surface 1011, the mounting portion 103 can also provide a limiting effect for the flat-bottomed container 2, thereby appropriately reducing the area required for the limiting portion 102, making the overall structure of the clamp 1 more compact and reducing the space occupied by the clamp 1.

[0041] In some embodiments provided by the present invention, the mounting portion 103 protrudes from the surface of the limiting portion 102 facing away from the main body 101. This configuration allows the mounting portion 103 to be taller, and the mounting hole 1031 on the mounting portion 103 to be deeper, allowing a round-bottomed vessel to be inserted deeper into the mounting hole 1031. This improves the retaining effect of the fixture 1 on the round-bottomed vessel and increases the stability of the round-bottomed vessel on the fixture 1.

[0042] In some embodiments provided by the present invention, the position-limiting portion 102 is provided with an arcuate surface 1021 for engaging with the outer circumference of the flat-bottomed container 2. In this embodiment, the position-limiting portion 102 engages with the outer circumference of the flat-bottomed container 2 via the arcuate surface 1021, thereby increasing the contact area between the position-limiting portion 102 and the flat-bottomed container 2. While retaining the flat-bottomed container 2, this also prevents stress concentration between the position-limiting portion 102 and the flat-bottomed container 2, which could damage the flat-bottomed container 2.

[0043] In some embodiments provided by the present invention, there are at least two limiting portions 102. Each limiting portion 102 is used to limit the flat-bottomed container 2, and a distance is provided between adjacent limiting portions 102. Compared to providing the limiting portion 102 as a single unit, in this embodiment, at least two limiting portions 102 are provided, and a distance is provided between adjacent limiting portions 102. This can reduce the weight of the clamp 1 while ensuring the effect on the flat-bottomed container 2, thereby reducing the energy consumption of the drive device 3 and achieving energy conservation and emission reduction.

[0044] refer to Figure 1 and Figure 2 As shown, in some embodiments provided by the present invention, a first groove 1012 is provided on the supporting surface 1011. One end of the first groove 1012 passes through the first edge of the main body 101, and the other end of the first groove 1012 is used to extend below the flat-bottomed container 2. The first groove 1012 is used to avoid the first gripping component 7 of the flat-bottomed container 2.

[0045] In this embodiment, a first groove 1012 is provided on the supporting surface 1011, and one end of the first groove 1012 passes through the first edge of the main body 101, and the other end extends to the bottom of the flat-bottomed vessel 2. When the clamping jaws of the first grasping component 7 grasp or place the flat-bottomed vessel 2, part of the structure of the clamping jaws can be placed in the first groove 1012, so that the clamping jaws of the first grasping component 7 can be avoided through the first groove 1012 to avoid interference between the clamping jaws and the supporting surface.

[0046] Optionally, two first gripping assemblies 7 may be provided along the motion path of the clamp 1 driven by the drive device 3. For example, the two first gripping assemblies 7 are provided on the same side of the motion path, and the two first gripping assemblies 7 are provided at the loading station and the unloading station, respectively. When the clamp 1 moves to the loading station, the first gripping assembly 7 at the loading station loads the material. When the clamp 1 moves to the unloading station, the first gripping assembly 7 at the unloading station unloads the material.

[0047] refer to Figure 1 and Figure 2 As shown, in some embodiments provided by the present invention, a second groove 1013 is provided on the supporting surface 1011. One end of the second groove 1013 passes through the second edge of the main body 101, and the other end of the second groove 1013 is configured to extend below the flat-bottomed container 2. The second groove 1013 is configured to avoid the first gripping assembly 7 of the flat-bottomed container 2. The second edge is adjacent to or opposite the first edge.

[0048] In this embodiment, a second groove 1013 is provided on the supporting surface 1011, and one end of the second groove 1013 passes through the second edge of the main body 101, and the other end extends to the bottom of the flat-bottomed vessel 2. When the clamping jaws of the second grasping component 8 grasp or place the flat-bottomed vessel 2, the clamping jaws can be placed in the second groove 1013, so that the clamping jaws of the second grasping component 8 can be avoided by the second groove 1013, thereby avoiding interference between the clamping jaws and the supporting surface.

[0049] Optionally, refer to Figure 2 As shown, the second grabbing assembly 8 is located at one end of the motion path of the clamp 1, and the first grabbing assembly 7 is located on one side of the motion path, or the second grabbing assembly 8 and the first grabbing assembly 7 are distributed on both sides of the motion path of the clamp 1. The first grabbing assembly 7 and the second grabbing assembly 8 are respectively arranged at the unloading station and the loading station.

[0050] The fixture 1 moves to the loading station, where the second grabbing assembly 8 loads the material, and the second groove 1013 avoids the second grabbing assembly 8. The fixture 1 moves to the unloading station, where the first grabbing assembly 7 unloads the material, and the first groove 1012 avoids the first grabbing assembly 7.

[0051] Therefore, by setting the first groove 1012 and the second groove 1013, and the first groove 1012 and the second groove 1013 are set at different edges of the main body 101, the clamp 1 can be suitable for application scenarios where the grabbing components of the loading station and the unloading station are located on different sides of the movement path.

[0052] Optionally, the first groove 1012 or the second groove 1013 is arranged to pass through the thickness direction of the main body 101. Such an arrangement can, on the one hand, increase the avoidance space of the first groove 1012 or the second groove 1013 in the thickness direction of the main body 101, thereby providing a better avoidance effect for the grasping component, and on the other hand, reduce the weight of the clamp 1.

[0053] A conveying mechanism is also provided in an embodiment of the present invention.

[0054] Specifically, the conveying mechanism includes a driving device 3 and the aforementioned clamp 1. The main body 101 is connected to the driving device 3, for example, the main body 101 and the driving device 3 are bonded, welded, or connected via a connector. The driving device 3 is used to drive the clamp 1 to move.

[0055] The conveying mechanism includes the clamp 1 and also includes all the above advantages of the clamp 1, so it will not be described in detail.

[0056] In some embodiments provided by the present invention, the conveying mechanism further includes a base 4, a guide member 5, and a sliding member 6. The guide member 5 is connected to the base 4, the sliding member 6 is slidably connected to the guide member 5, the sliding member 6 is connected to the main body 101, and the driving device 3 connects the main body 101 and the base 4. For example, the guide member 5 is provided with a slide groove, and the sliding member 6 is slidably connected to the slide groove.

[0057] In this embodiment, all components of the conveying mechanism are mounted on the base 4, forming a single unit. This enhances the integrity of the conveying mechanism and facilitates separate assembly and commissioning of the conveying mechanism, thereby reducing the difficulty of assembly and commissioning and shortening on-site commissioning time. The guide member 5 and the slider 6 slide together to guide the clamp 1, allowing them to share the load or impact on the drive device 3, resulting in smoother operation of the clamp 1 and a longer service life of the drive device 3.

[0058] Optionally, the running path of the clamp 1 is set to a straight line, and the conveying mechanism can be set to a cylinder, an oil cylinder, a screw-nut mechanism or a rack-and-pinion mechanism.

[0059] Alternatively, the running path of the clamp 1 can also be set as an arc, and the conveying mechanism can be set as a rack and pinion mechanism.

[0060] In some embodiments provided by the present invention, the conveying mechanism further includes a position detection device and a control assembly. The position detection device and the drive device 3 are both electrically connected to the control assembly. The position detection device is used to detect the position information of the clamp 1. For example, the position detection device is configured as a proximity switch, an induction switch, or a travel switch.

[0061] In this embodiment, the position information of the clamp 1 is obtained by the position detection device, so that the control component can accurately control the stop position of the drive device 3 according to the position information, thereby making the stop position of the clamp 1 more accurate, so as to facilitate subsequent loading and unloading.

[0062] An embodiment of the present invention further provides a detection line.

[0063] Specifically, the inspection line includes the clamp 1 described above or the conveying mechanism described above.

[0064] The detection line includes the fixture 1 or the conveying mechanism, and also includes all the above advantages of the fixture 1 or the conveying mechanism, so it will not be described in detail.

[0065] In some embodiments provided by the present invention, the detection line further includes a grabbing assembly, which is used to place a flat-bottomed vessel 2 or a round-bottomed vessel on the fixture 1 or remove the flat-bottomed vessel 2 or the round-bottomed vessel from the fixture 1 .

[0066] Optionally, the grabbing assembly includes a first grabbing assembly 7 and a second grabbing assembly 8. Figure 2 As shown, the second gripping assembly is located at one end of the motion path of the clamp 1, and the first gripping assembly 7 is located on one side of the motion path. Alternatively, the second gripping assembly 8 and the first gripping assembly 7 are distributed on both sides of the motion path of the clamp 1. The first gripping assembly and the second gripping assembly are respectively arranged at the unloading station and the loading station. When the clamp 1 moves to the loading station, the second gripping assembly 8 at the loading station loads the material, and the second groove 1013 avoids the second gripping assembly 8. When the clamp 1 moves to the unloading station, the first gripping assembly 7 at the unloading station unloads the material, and the first groove 1012 avoids the first gripping assembly 7.

[0067] Alternatively, the gripping assembly includes two first gripping assemblies 7. For example, the two first gripping assemblies 7 are disposed on the same side of the motion path of the clamp 1, and the two first gripping assemblies 7 are disposed at the loading station and the unloading station, respectively. When the clamp 1 moves to the loading station, the first gripping assembly 7 at the loading station loads the material. When the clamp 1 moves to the unloading station, the first gripping assembly 7 at the unloading station unloads the material.

[0068] Optionally, at least one of the first grasping assembly 7 and the second grasping assembly 8 includes a robotic arm and a gripper provided on the robotic arm, and the gripper may be provided as a pneumatic finger or a pneumatic gripper.
