For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] Example 1:

[0040] like Figures 1 to 3 As shown, the fixture for total moisture testing in this embodiment includes a support 1. The support 1 is provided with a first clamping component 3 and a second clamping component 4. The first clamping component 3 includes a pair of opposing jaws 32 for clamping the body of the sample bottle 91. The second clamping component 4 includes a tray support 41 for supporting the edge of the sample tray 92.

[0041] The clamp for total moisture test in the embodiment can clamp the sample bottle 91 when the clamp is in the form of clamping the sample bottle 91, the clamping jaw 32 clamps the bottle body of the sample bottle 91, and the clamping of the sample bottle 91 is realized; the clamp can clamp the sample disc 92 when the clamp is in the form of clamping the sample disc 92, the disc holder 41 supports the edge of the sample disc 92, and the clamping of the sample disc 92 is realized; when it is necessary to convert the clamping form of the clamp, the angle of the clamp is adjusted, and the clamping form of the clamp can be switched. The clamp for total moisture test in the embodiment can realize the conversion of the clamping form of the clamp in the form of clamping the sample bottle 91 and the form of clamping the sample disc 92 by integrating the clamping jaw 32 and the disc holder 41 on the same clamp, adjusting the angle of the clamp, and realizing the clamping of the sample bottle 91 and the sample disc 92 without needing to be equipped with multiple mechanical clamping jaws and needing to replace the mechanical clamping jaws, so that the operation is simple, the work efficiency is high, and the space utilization rate is high.

[0042] Further, in the embodiment, the first clamping assembly 3 further includes an opening and closing driving member 31, the opening and closing driving member 31 is arranged on the support 1 and connected with the clamping jaw 32 to drive the oppositely arranged clamping jaw 32 to open and close. The opening and closing driving member 31 (such as a pneumatic cylinder) drives a pair of clamping jaws 32 to perform opening and closing movement, corresponding to the “opening” and “grasping” states of the clamping jaw 32. When the clamping jaw 32 is opened, the opening size is greater than the diameter of the sample bottle 91. After the clamping jaw 32 extends to the position of the bottle body of the sample bottle 91, the opening and closing driving member 31 drives the clamping jaw 32 to close. After the clamping jaw 32 is closed, the bottle body of the sample bottle 91 is clamped, the clamping of the sample bottle 91 is realized, and the structure is simple and reliable. Of course, in other embodiments, the number of clamping jaws 32 can be increased to make the clamping more stable.

[0043] Further, in the embodiment, the first clamping assembly 3 further includes a mounting seat 33, and the opening and closing driving member 31 is arranged on the support 1 through the mounting seat 33. The opening and closing driving member 31 is supported by the mounting seat 33, so that the opening and closing driving member 31 drives the clamping jaw 32 to open and close more stably.

[0044] Further, in the embodiment, the clamping jaw 32 is in a V shape. The clamping jaw 32 in a V shape can form four-point contact (two points of each of the two clamping jaws 32) when clamping the sample bottle 91, and the clamping stability is better.

[0045] Further, in the embodiment, the disc holder 41 is arranged on the support 1, an opening 42 is arranged at the end of the disc holder 41 away from the support 1, and the length of the opening 42 is greater than the diameter of the sample disc 92. When the sample disc 92 is clamped, the disc holder 41 moves towards the sample disc 92, the sample disc 92 passes through the opening 42 and enters the disc holder 41, and when the disc holder 41 is aligned with the sample disc 92, the disc holder 41 rises, the edge of the sample disc 92 is supported by the disc holder 41, and the clamping of the sample disc 92 is realized.

[0046] Furthermore, in this embodiment, the tray support 41 includes support arms 411 disposed on both sides of the opening 42. A first limiting member 412 is provided at the end of the support arm 411 near the opening 42, and a second limiting member 413 is provided at the end away from the opening 42. When the sample tray 92 is lifted by the tray support 41 (i.e., by the two support arms 411), the first limiting member 412 can restrict the movement of the tray support 41 towards the opening 42, and the second limiting member 413 can restrict the movement of the tray support 41 away from the opening 42, resulting in better clamping stability.

[0047] Furthermore, in this embodiment, the minimum distance between the two first limiting members 412, the minimum distance between the two second limiting members 413, and the minimum distance between the first limiting members 412 and the second limiting members 413 on the same side are all less than the diameter of the edge of the sample tray 92. The minimum distance between the two first limiting members 412 is less than the diameter of the edge of the sample tray 92, preventing the sample tray 92 from detaching from the direction facing the opening 42; the minimum distance between the two second limiting members 413 is less than the diameter of the edge of the sample tray 92, preventing the sample tray 92 from detaching from the direction away from the opening 42; the minimum distance between the first limiting members 412 and the second limiting members 413 on the same side is less than the diameter of the edge of the sample tray 92, preventing the sample tray 92 from detaching from the direction perpendicular to the opening 42. This allows the first limiting members 412 and the second limiting members 413 to cooperate in limiting the sample tray 92 in all directions on the plane of the tray support 41, resulting in better limiting effect and better clamping stability.

[0048] Preferably, in this embodiment, both the first limiting member 412 and the second limiting member 413 are arc-shaped. The diameters of the arcs of the first limiting member 412 and the second limiting member 413 are the same, meaning that the two first limiting members 412 and the two second limiting members 413 are four arc segments of the same circle. The diameter of this circle is slightly larger than the diameter of the edge of the sample plate 92. This structure is simple and reasonable, and the arc-shaped first limiting member 412 and the second limiting member 413 can fit the circular sample plate 92 more closely, resulting in a better limiting effect. Of course, in other embodiments, the first limiting member 412 and the second limiting member 413 can also be limiting posts, limiting blocks, etc.

[0049] Furthermore, such as Figure 3 As shown, in this embodiment, the first clamping component 3 and the second clamping component 4 are arranged perpendicularly. Specifically, the clamping direction of the grippers 32 is... Figure 3 The vertical direction in the middle) and the clamping direction of the plate support 41 ( Figure 3 (Horizontal) Vertical, when the clamp is in the clamping sample tray 92 configuration, it can be rotated 180° around the arrangement direction of the second clamping assembly 4 first. Figure 3 (in the horizontal direction), and then around the direction of the intersection line of the plane where the first clamping component 3 is located and the plane where the second clamping component 4 is located (in the horizontal direction). Figure 3The clamp can be converted into the sample bottle 91 clamping mode by rotating 90° along the direction perpendicular to the paper surface, and vice versa. The conversion process is simple. Of course, in other embodiments, the first clamping assembly 3 and the second clamping assembly 4 can also be arranged in other forms, for example, the first clamping assembly 3 and the second clamping assembly 4 can be arranged in an up-down interval, and the clamping assembly can be switched by moving the clamp up and down. The first clamping assembly 3 and the second clamping assembly 4 can also be arranged relatively, and the clamping assembly can be switched by rotating the clamp by 180°.

[0050] Embodiment two:

[0051] As shown in Figures 5 to 9 , the transfer device for total moisture testing of the present embodiment comprises a transfer robot 2, and the transfer robot 2 is provided with the clamp for total moisture testing of embodiment one.

[0052] The transfer device for total moisture testing of the present embodiment installs the clamp for total moisture testing of embodiment one on the transfer robot 2. The transfer robot 2 can adjust the angle of the clamp according to the actual sample container requirements, realize the conversion of the sample bottle 91 clamping mode and the sample disc 92 clamping mode of the clamp, and then drive the converted clamp to clamp the corresponding sample container, and then drive the clamped sample container to move, thereby realizing the rapid transfer of different sample containers with high work efficiency.

[0053] Further, in the present embodiment, the transfer robot 2 is a six-axis robot, and the sixth axis 22 of the transfer robot 2 is connected to the first clamping assembly 3 through a connecting piece 21. The connecting piece 21 (such as a connecting flange) is arranged on the first clamping assembly 3 (specifically, the mounting seat 33 of the first clamping assembly 3). When the clamp is in the sample bottle 91 clamping mode, the sixth axis 22 can be rotated by 180° first, and then the fifth axis 23 can be rotated by 90°, thereby converting the clamp into the sample disc 92 clamping mode. Similarly, the clamp can be converted into the sample bottle 91 clamping mode by reversing the operation. The conversion process is simpler and the operation is more convenient.

[0054] Of course, in other embodiments, the connecting piece 21 can also be arranged on the second clamping assembly 4 (as shown in Figure 4 ) or the bracket 1.
