DETAILED DESCRIPTION

[0059] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0060] Example 1

[0061] A synchronous multi-group stacking assembly, comprising: a narrow conveyor belt 1, a transfer box 2, a transfer box pushing assembly, a supporting platform 3, and a supporting platform lifting assembly;

[0062] like Figure 1As shown, a narrow conveyor belt 1 is arranged above the base platform 9 and on the rear side, and the narrow conveyor belt 1 is divided into a conveyor belt box and a conveyor belt; two conveyor belts are arranged, and the two conveyor belts are respectively arranged at positions close to both sides of the conveyor belt box; when the flat plate culture medium 8 is conveyed on the narrow conveyor belt 1, the bottom surface of the flat plate culture medium 8 is in contact with the two conveyor belts at the same time and is carried and moved by the conveyor belts.

[0063] A support platform 3 is arranged on one side of the discharge side of the narrow conveyor belt 1, and a lifting component is arranged below the support platform 3, and the lifting component is arranged as a telescopic rod 7; in this embodiment, two telescopic rods 7 are arranged; the base end of the telescopic rod 7 is arranged inside the base platform 9; the upper end of the telescopic rod 7 is arranged on the lower bottom surface of the support platform 3; the telescopic rod 7 can use an electric telescopic rod or a hydraulic telescopic rod, which is driven and controlled by a control switch;

[0064] The control switch of the telescopic rod 7 is connected to the PLC; the PLC is used to control the telescopic rod 7 to descend to a certain distance each time.

[0065] A transfer box push assembly is arranged on the other side of the discharge side of the narrow conveyor belt 1; a transfer box 2 is connected to the transfer box push assembly; the above-mentioned transfer box push assembly includes: a push control box 5, a motor 6, a transmission rod 502, a push rod 501 and a gear 503; the push control box 5 is arranged on one side of the discharge side of the narrow conveyor belt 1; a motor 6 is arranged on one side of the push control box 5; a transmission rod 502 is arranged in the push control box 5; one end of the transmission rod 502 is arranged on the rotor of the motor 6, and the other end of the transmission rod 502 is rotated to the side wall of the push control box 5 on the opposite side of the motor 6 On the top; two gears 503 are set on the transmission rod 502; a tooth structure is set on the lower surface of the push rod 501; the gear 503 is engaged with the lower surface of the push rod 501 through teeth; one end of the push rod 501 extends from the front of the push control box 5 and is connected to the rear side of the transfer box 2; the push rod 501 can be extended and retracted in the push control box 5; the motor 6 is connected to the PLC for communication; when the motor 6 is started, the transmission rod 502 rotates, which can drive the gear 503 to rotate, and the gear 503 drives the push rod 501 engaged therewith to extend, so that the transfer box 2 can be pushed from above the narrow conveyor belt 1 to above the supporting platform 3.

[0066] When the transfer box 2 is not displaced, it is located above the narrow conveyor belt 1, specifically above the discharge side; the function of the transfer box 2 is to allow the plate culture medium on the narrow conveyor belt 1 to enter the transfer box 2, and the transfer box 2 carries the plate culture medium to the support table 3; the transfer box 2 repeatedly transfers the plate culture medium to the same position above the support table 3, so that the plate culture medium can be stacked;

[0067] The structure of the transfer box 2 is set as follows: a hollow structure is set inside the transfer box 2, and the bottom surface of the transfer box 2 is set as an open structure; the left side of the hollow structure is set as an open structure; the flat plate culture medium can enter the hollow structure inside the transfer box 2 from the open structure on the left side of the transfer box 2; the width of the hollow structure inside the transfer box 2 is slightly larger than the outer diameter of the flat plate culture medium; the two side surfaces of the hollow structure can just contact the two sides of the flat plate culture medium; the flat plate culture medium is clamped to carry the flat plate culture medium and transferred to the supporting table 3; when it reaches above the supporting table 3, the operator takes the flat plate culture medium out of the transfer box 2.

[0068] The control switch of the telescopic rod 7 under the supporting platform 3 is connected to the PLC, and the PLC sets the height value of the telescopic rod 7 each time it descends to be equal to the thickness value of the flat plate culture medium; initially, the upper surface of the supporting platform 3 rises to be flush with the upper surface of the narrow conveyor belt 1; as the flat plate culture medium enters the transfer box 2, the transfer box 2 begins to carry the flat plate culture medium toward the supporting platform 3 under the action of the push rod 501, and when it moves to the top of the supporting platform 3, the PLC controls the motor to stop the further extension of the push rod 501; then the staff takes the flat plate culture medium out of the transfer box 2 to the top of the supporting platform 3; at the same time, the PLC detects that one transfer is completed, and the height drops by the thickness of a flat plate culture medium; the transfer box 2 retreats to the top of the narrow conveyor belt 1, continues to collect the flat plate culture medium, and prepares to complete the second transfer; after the second transfer is completed, the second flat plate culture medium is stacked on the first flat plate culture medium; this is repeated until the flat plate culture medium is stacked to a certain height, and the staff performs unified packaging.

[0069] Example 2

[0070] Based on Example 1, in Example 1, the flat plate culture media coming down from the wide conveyor belt are generally transported in groups of several, and each group is separated by a certain distance; this can improve the stacking efficiency and complete the stacking of multiple groups at the same time. Normally, a group of flat plate culture media needs to all enter the transfer box 2 before being transferred uniformly; in Example 1, it is necessary to manually count and monitor the number of cells entering the transfer box 2, and then start the motor 6 to transfer the transfer box 2 carrying the flat plate culture media.

[0071] like Figure 2 and Figure 5 As shown, in this embodiment, an infrared emitter 202 is arranged near the left edge of the hollow structure in the transfer box 2, that is, the infrared emitter 202 is arranged above the entrance of the transfer box 2; the narrow conveyor belt 1 is divided into a conveyor belt box and a conveyor belt; two conveyor belts are arranged, and the two conveyor belts are respectively arranged at positions close to both sides of the conveyor belt box, and an infrared sensor 101 is embedded in the center of the conveyor belt box; the infrared sensor 101 is arranged opposite to the infrared emitter 202; the infrared sensor 101 is connected to the PLC for communication.

[0072] The flat plate culture medium entering the transfer box 2 will pass through the infrared transmitter 202. Under normal circumstances, the infrared light emitted by the infrared transmitter 202 will be received by the infrared sensor 101. When a flat plate culture medium enters the transfer box 2, the infrared light of the infrared transmitter 202 will be blocked once. The number of flat plate culture media in a group is preset. When the PLC collects the number of blocking signals from the infrared sensor 101 equal to the preset number of flat plate culture media, the PLC will control the motor to start, and the push rod 501 will push the transfer box 2, so that the transfer box 2 can carry the flat plate culture medium to complete the transfer. In this way, the automatic recording of the number of flat plate culture media entering the transfer box 2 is realized, and after a group of flat plate culture media completely enters the transfer box 2, the transfer box 2 automatically starts to carry the flat plate culture medium for transfer.

[0073] Example 3

[0074] Based on Example 1, in Example 1, the flat plate culture medium in the transfer box 2 is in contact with the side of the flat plate culture medium through the hollow structure side wall of the transfer box 2, so that the flat plate culture medium is stuck in the transfer box 2, and the transfer box 2 carries the flat plate culture medium for transfer; that is, there is essentially no clamping structure between the transfer box 2 and the flat plate culture medium; although the distance between the support platform 3 and the narrow conveyor belt 1 is very short; but during the movement of the transfer box 2, the flat plate culture medium inside may still be at risk of falling.

[0075] like Figures 4 to 6 As shown, in this embodiment, clamping components are arranged on both sides of the hollow structure of the transfer box 2; there is a certain gap between the two sides of the hollow structure and the flat plate culture medium; the clamping components are used to clamp and fix the flat plate culture medium from both sides to prevent the flat plate culture medium from falling during transfer; when the transfer box 2 carries the flat plate culture medium to the top of the supporting platform 3, the clamping components are released, and the flat plate culture medium falls from the open structure on the bottom surface of the transfer box 2 onto the supporting platform 3.

[0076] The above-mentioned clamping assembly is configured as an electromagnetic clamping block 201; Figure 5 , grooves are provided on both sides of the hollow structure in the transfer box 2, and the electromagnetic clamping blocks 201 are movably arranged in the grooves; the electromagnetic clamping blocks 201 are connected to the electromechanical components; the electromechanical components are used to control the two electromagnetic clamping blocks 201 to produce mutual magnetic attraction; clamp the flat plate culture medium in the middle; the electromechanical components are connected to the PLC for communication. When the electromagnetic clamping blocks 201 carry the flat plate culture medium and transfer it to the top of the support platform 3, the electromechanical components are powered off, so that the magnetism of the two electromagnetic clamping blocks 201 disappears, and the flat plate culture medium falls onto the support platform 3. In this way, it can be ensured that each time the transfer box 2 carries the flat plate culture medium, the flat plate culture medium can be stably clamped.

[0077] The electromagnetic clamping block 201 and the electromechanical components belong to the prior art, and their specific structures and principles are not described in detail here.

[0078] Example 4

[0079] Based on Example 1, in Example 1, the flat plate culture medium is transferred to the supporting table 3. After the specified number of stacks are completed, the staff is required to complete the packaging of the stacked flat plate culture medium on the supporting table 3; after the packaging is completed, the supporting table 3 can perform the next stacking support function; this will undoubtedly delay work efficiency.

[0080] like Figure 7 and Figure 8 As shown, in this embodiment, a packaging table 4 is arranged on the upper surface of the base platform 9 near the front side; the supporting platform 3 includes: a base plate 301, a sliding plate 302, a slide groove 303 and a slide rail 304; the slide groove 303 is embedded in the upper surface of the base plate 301; the slide rail 304 is arranged on the lower surface of the sliding plate 302; the slide rail 304 is movably arranged in the slide groove 303, so that the sliding plate 302 can slide back and forth relative to the base plate 301.

[0081] Before stacking, a plastic gasket 10 is placed on the sliding plate 302, and the plate culture medium falls on the gasket 10 of the sliding plate 302; after the specified number of stackings are completed, the upper surface of the sliding plate 302 is kept flush with the upper surface of the packaging table 4; the sliding plate 302 is moved so that the sliding plate 302 is docked on the packaging table 4, and then the gasket 10 is slowly pulled so that the stacked plate culture medium is dragged onto the packaging table 4 along with the gasket 10, and then the sliding plate 302 is restored to its original position to continue the next stacking; and the staff will package the plate culture medium stacked last time on the packaging table 4.
