[0023] The utility model is further described below in conjunction with the accompanying drawings.

[0024] Example 1

[0025] like Figure 1 As shown, a tray hook-pull transfer device is used to cooperate with the storage slide and the extraction slide of the storage and access port of the sample refrigerator 1, and is used to realize the automatic storage and removal of the sample tray storing the food sample box in the sample refrigerator 1.

[0026] like Figure 1 and Figure 2 As shown, the tray hook-pull transfer device includes a frame, an in-and-out transmission assembly, a motor 6-1 and two hook-pull assemblies. The in-and-out transmission assembly includes a transmission belt 6-2 and two transmission wheels 6-3. The two transmission wheels 6-3 with vertical axes are both rotatably connected to the frame; the two transmission wheels 6-3 are connected by transmission belts 6-2. The arrangement direction of the two transmission wheels 6-3 is parallel to the length direction of the storage slide and the extraction slide (that is, the movement direction of the sample tray 3 when storing or taking out the sample refrigerator 1). The motor 6-1 is fixed on the frame, and the output shaft is fixed to one of the transmission wheels 6-3.

[0027] There are two hook-pull assemblies. The two hook-pull assemblies are respectively installed on the opposite sides of the in-and-out transmission assembly. The hook-pull assembly includes a guide rail, a slider 6-4, a hook claw 6-5 and a steering gear 6-6. The guide rail is fixed on the frame. The slider 6-4 is slidably connected to the guide rail; the slider 6-4 is fixed to the transmission belt 6-2. The steering gear 6-6 is fixed on the slider 6-4. The output shaft of the steering gear 6-6 is vertically arranged. The inner end of the hook claw 6-5 is fixed on the output shaft of the steering gear 6-6. The steering gear 6-6 can drive the hook claw 6-5 to flip outward or retract inward. The outer end of the hook claw 6-5 is provided with a hook portion.

[0028] The sliders 6-4 in the two hook-pull assemblies are respectively fixed to the two straight sections on the transmission belt 6-2, and divide the transmission belt 6-2 into two equal length sections. Therefore, the two sliders 6-4 are symmetrical about the center of the annular area surrounded by the transmission belt 6-2, and move in opposite directions with the transmission belt 6-2. The hook parts of the hook claws 6-5 in the two hook-pull assemblies face opposite directions, and are respectively used to deliver the sample tray into the sample refrigerator 1 and take out the sample tray from the sample refrigerator 1.

[0029] like Figure 3 As shown, four sample box installation positions arranged in sequence are arranged on the sample tray 3. Each sample box installation position can be used to place a food sample box for storing sampled food and provide positioning for the food sample box.

[0030] Grooves 3-1 are provided at both ends of the two sides of the sample tray 3. When the sample tray 3 is placed in the storage slide 4, the extraction slide 5, the loading area 1-1 and the removal area 1-2 in the sample refrigerator 1, the groove 3-1 on the sample tray 3 and the hook 6-5 in the tray hook transfer device 6 are at the same height. The hook 6-5 can be turned outward to hook the groove 3-1 on the sample tray 3, thereby driving the sample tray 3 to move in and out through the movement of the transmission belt 6-2. The four grooves 3-1 on the sample tray 3 form both axial symmetry and central symmetry, so that no matter which direction the sample tray 3 is sent into the storage slide 4, there is a groove 3-1 corresponding to the position of the hook 6-5 in the tray hook transfer device.

[0031] Under the drive of the steering gear 6-6, the hook 6-5 has two extreme positions, namely, a standby position where the hook portion at the outer end of the hook 6-5 is close to the transmission belt 6-2, and a working position where the hook portion at the outer end of the hook 6-5 is away from the transmission belt 6-2. When the hook 6-5 is in the standby position, the hook 6-5 will not contact the corresponding sample tray 3. When the hook 6-5 is in the working position, the hook portion at the outer end of the hook 6-5 extends into the groove 3-1 of the corresponding sample tray 3.

[0032] When the hook claw 6-5 of the input hook-pull assembly is in the working position, the hook portion at the outer end of the hook claw 6-5 faces the side away from the storage slide, and can hook the groove 3-1 of the sample tray 3 and drive the sample tray 3 into the sample refrigerator. When the hook claw 6-5 of the output hook-pull assembly is in the working position, the hook portion at the outer end of the hook claw 6-5 faces the side close to the extraction slide, and can hook the groove 3-1 of the sample tray 3 and drive the sample tray 3 out of the sample refrigerator.

[0033] Example 2

[0034] like Figure 4As shown, a storage and access device for a sample refrigerator tray comprises a storage and access plate 2, a storage slide 4, an extraction slide 5, and a tray hook transfer device 6 as described in Example 1. The storage and access plate 2 is arranged at the storage and access port of the sample refrigerator 1; the storage slide 4 and the extraction slide 5 for storing the sample tray 3 are installed on the storage and access plate 2. The storage and access plate 2 can be fixed at the bottom of the storage and access port, or it can be movably connected to the bottom of the storage and access port; the storage and access plate 2 can be maintained in a horizontal state to carry the storage or output of the sample tray 3. The sample refrigerator 1 is provided with a loading area 1-1 and a removal area 1-2 for the sample tray 3. The sample refrigerator 1 can transport the food tray placed by the staff in the loading area 1-1 to any storage area inside the sample refrigerator 1, and can also transport the food tray stored in any storage area inside the sample refrigerator 1 to the removal area 1-2. The storage slide 4 and the extraction slide 5 are aligned with the loading area 1-1 and the removal area 1-2 in the sample refrigerator 1, respectively.

[0035] like Figure 1 As shown, the method of transferring food trays inside the sample refrigerator 1 can be achieved by using a three-degree-of-freedom mobile platform in conjunction with a mechanical gripper (for example, the solution described in the patent application with publication number "CN108278811A"), or by other tray transfer structures; these structures have many mature cases in the prior art and are not the focus and protection scope of the present utility model, so they are not elaborated in the present utility model.

[0036] The tray hook and pull transfer device 6 is installed between the loading area 1-1 and the retrieval area 1-2 in the sample retention refrigerator 1, and can simultaneously or independently complete the actions of "pulling the sample retention tray 3 placed by the staff on the storage slide 4 into the loading area 1-1 in the sample retention refrigerator 1" and "pushing the sample retention tray 3 in the loading area 1-1 in the sample retention refrigerator 1 to the extraction slide 5 for the staff to take".

[0037] In the tray hook-pull transfer device, one of the hook-pull components is an input hook-pull component, which is located on the side of the in-and-out transmission component close to the loading area 1-1 of the sample retention refrigerator, and is used to pull the sample tray 3 on the storage slide 4 into the loading area 1-1 of the sample retention refrigerator 1; the other hook-pull component is an output hook-pull component, which is located on the side of the in-and-out transmission component close to the taking-out area 1-2 of the sample retention refrigerator 1, and is used to push the sample tray 3 on the taking-out area 1-2 of the sample retention refrigerator 1 to the extraction slide 5.

[0038] In the initial state, the input hook assembly is located at the end of the in-out transmission assembly close to the storage slide 4, so as to hook the end of the sample tray 3 on the storage slide 4 close to the loading area 1-1 of the sample refrigerator 1. The output hook assembly is located at the end of the in-out transmission assembly close to the storage slide 4, so as to hook the end of the sample tray 3 on the removal area 1-2 of the sample refrigerator 1 away from the extraction slide 5.

[0039] This embodiment provides a non-essential preferred technical solution, in which the inner edge of the access plate 2 and the bottom edge of the access port form a revolving pair. When the access plate 2 is flipped to a vertical state, the access port on the sample refrigerator 1 is closed. The locking assembly 7 includes an electromagnet and a locking block. The electromagnet is fixed to the top of the access port. The locking block is made of ferromagnetic material and is fixed on the access plate 2. The positions of the electromagnet and the locking block correspond. When the access plate 2 closes the access port, the access port is in contact. The locking assembly 7 achieves locking of the access plate 2 by energizing the electromagnet to adsorb the locking block.

[0040] This embodiment provides a non-essential preferred technical solution, where the access plate 2 is driven to flip by an opening and closing drive mechanism; the opening and closing drive mechanism includes a cylinder. The cylinder body and the frame form a revolving pair; the push rod (i.e., piston rod) of the cylinder and the access plate 2 form a revolving pair. The access plate 2 is driven to switch between a horizontal state and a vertical state by the extension and contraction of the cylinder.

[0041] This embodiment provides a non-essential preferred technical solution, in which a positioning assembly (not shown in the figure) is installed near the access port in the sample refrigerator 1; the positioning assembly includes a positioning baffle and a push-pull electromagnet. The push-pull electromagnet is fixed in the sample refrigerator 1. A positioning baffle is fixed on the push rod of the push-pull electromagnet. The positioning baffle has two extreme positions under the drive of the push-pull electromagnet; when the positioning baffle is in the first extreme position, the positioning baffle is aligned with the inner end of the storage slide 4, which can limit the extreme position of the staff pushing the sample tray 3 inward; when the positioning baffle is in the second extreme position, the positioning baffle is offset from the inner end of the storage slide 4, and no longer blocks the sample tray 3, so that the tray hook transfer device 6 can drive the sample tray 3 into the sample refrigerator 1.

[0042] The working principle of this embodiment is as follows (this working principle is only one way to realize the function of the utility model and is not an essential technical feature):

[0043] When storing a food sample box in the sample refrigerator 1, place the sample box on the sample tray 3. The sample box contains food that needs to be sampled. Place the sample tray 3 on the storage slide 4 and push it inward to the limit position so that the sample tray 3 is against the positioning baffle. After that, the push-pull electromagnet drives the positioning baffle to slide so that the positioning baffle is staggered with the storage slide 4. The motor 6-1 in the tray hook-pull transfer device 6 drives the two hook-pull components to move in opposite directions, so that the hook claw 6-5 on the hook-pull component for storing the sample tray 3 is aligned with the groove 3-1 on the sample tray 3 located on the storage slide 4; finally, the hook claw 6-5 on the hook-pull component for storing the sample tray 3 is turned outward and hooked on the groove 3-1 on the sample tray 3; the motor 6-1 in the tray hook-pull transfer device 6 drives the two hook-pull components to move, and pulls the sample tray 3 on the storage slide 4 into the sample refrigerator 1.

[0044] When taking out the food sample box in the sample refrigerator 1, the sample refrigerator 1 transfers the sample tray 3 to be taken out to the take-out area 1-2; the motor 6-1 in the tray hook transfer device 6 drives the two hook assemblies to move in opposite directions, so that the hook claw 6-5 on the hook assembly used to take out the sample tray 3 is aligned with the groove 3-1 on the sample tray 3 located in the take-out area 1-2. Finally, the hook claw 6-5 on the hook assembly used to take out the sample tray 3 flips outward and hooks the groove 3-1 on the sample tray 3; the motor 6-1 in the tray hook transfer device 6 drives the two hook assemblies to move, and pulls the sample tray 3 on the take-out area 1-2 of the sample refrigerator 1 into the extraction slide 5 for the staff to take, and the sampling is completed.

[0045] The above-mentioned sample storage method and sampling method can be executed simultaneously.
