Description

Technical Field

[0001] The utility model belongs to the technical field of microorganism culture devices, and in particular relates to a flat plate culture medium hooking and conveying device. Background Art

[0002] A culture dish is a glass or plastic round container used to hold liquid culture medium or solid agar culture medium for cell culture. The culture dish consists of a bottom and a lid, and is a chemical device used to culture bacteria. Its main material is glass or plastic. A culture dish is usually made of solid culture medium for flat plate culture. The flat plate culture medium is made by filling the sterilized agar culture medium into the culture dish, which is then sealed with a culture dish lid to allow the agar culture medium to condense in the dish.

[0003] Batch plate culture medium is produced on the assembly line; the culture dish is loaded, opened, agar filled and closed on the sterile and closed wide conveyor belt. After the filled plate culture medium is conveyed to the end of the wide conveyor belt, it needs to be changed from a side-by-side queue to a longitudinal arrangement, and then transferred to the narrow conveyor belt responsible for coding to be coded at the bottom of the culture dish. Therefore, the two conveyor belts are in a vertical relationship to complete the formation conversion of the culture dish. At present, on the assembly line, since there is no auxiliary mechanical structure associated with the wide conveyor belt and the narrow conveyor belt, manual operation is required to transfer the plate culture medium from the wide conveyor belt to the narrow conveyor belt; manual operation requires a special person to use a hook rod to move the plate culture medium at this link; the plate culture medium is in a neat side-by-side arrangement on the wide conveyor belt; but after manual operation, the arrangement between the plate culture medium may be uneven after the plate culture medium is transferred to the narrow conveyor belt. Utility Model Content

[0004] The utility model provides a flat plate culture medium hooking and conveying device, which is set between the mutually perpendicular wide conveyor belt discharge port and the narrow conveyor belt feed port; the hooking and conveying device is provided with a hooking and conveying plate that can reciprocate in the horizontal direction and rise and fall in the vertical direction; by coordinating the horizontal reciprocating movement of the hooking and conveying plate with the vertical lifting movement, the flat plate culture medium on the wide conveyor belt can be continuously hooked and transferred to the narrow conveyor belt; and because the hooking and conveying plate will not shift when moving in the horizontal and vertical directions; therefore, when the flat plate culture medium is transferred from the wide conveyor belt to the narrow conveyor belt, the flat plate culture medium can be kept neatly arranged from side by side to longitudinally arranged; avoiding the situation where the bottom inkjet coding of the flat plate culture medium is offset due to the uneven queue. The utility model solves the problem that the current flat plate culture medium production line needs manual operation when transferring the flat plate culture medium from the wide conveyor belt to the narrow conveyor belt, which will destroy the originally neat queue of the flat plate culture medium and cause the bottom inkjet coding to shift.

DETAILED DESCRIPTION

[0050] 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.

[0051] Example 1

[0052] A flat plate culture medium hooking and conveying device, comprising: a wide conveyor belt 1, a narrow conveyor belt 2, a hooking and conveying plate 8, a hooking and conveying plate horizontal moving component and a hooking and conveying plate lifting component;

[0053] like Figure 1 As shown, the discharge side of the wide conveyor belt 1 is vertically connected to the feed side of the narrow conveyor belt 2; a hook plate horizontal moving assembly is bridged between the discharge side of the wide conveyor belt 1 and the feed side of the narrow conveyor belt 2; the hook plate horizontal moving assembly in this embodiment includes: an n-type bracket 3, a support plate 4, a slide bar 5 and an electric control slider 6; the n-type bracket 3 is horizontally erected above the discharge side of the wide conveyor belt 1; the support plate 4 is arranged on the side close to the feed side of the narrow conveyor belt 2, where the side refers to the side of the narrow conveyor belt 2 that does not contact the wide conveyor belt 1; the slide bar 5 is arranged above the n-type bracket 3 and the support plate 4;

[0054] Specifically, one end of the slide bar 5 is centered on the upper edge of the n-type bracket 3, and the other end is centered on the upper edge of the support plate 4; an electric-controlled slider 6 is movably arranged on the slide bar 5; the electric-controlled slider 6 can move horizontally back and forth on the slide bar 5 under electric drive; a hook plate lifting assembly is arranged below the electric-controlled slider 6; the hook plate 8 is arranged at the lower end of the hook plate lifting assembly; in this way, when the electric-controlled slider 6 moves horizontally on the slide bar 5, it can drive the hook plate 8 to move horizontally.

[0055] The above-mentioned electric control slider 6 is an existing product that can be directly purchased. The structure and control circuit of the electric control slider 6 belong to the existing technology and will not be described in detail here.

[0056] The culture dish is filled with agar culture medium on the wide conveyor belt 1 to obtain a flat culture medium; the flat culture medium is transported by the wide conveyor belt 1 to the discharge side of the wide conveyor belt 1; at this time, the hook plate 8, under the action of the electric control slider 6, realizes the transfer of the flat culture medium on the wide conveyor belt 1 to the narrow conveyor belt 2; in this process, the flat culture medium originally in a parallel formation on the wide conveyor belt 1 is converted into a longitudinal formation and transported on the narrow conveyor belt 2, and the coding mechanism under the narrow conveyor belt 2 performs coding on the bottom of the flat culture medium. Since the hook plate 8 is a vertical flat plate structure, and the connection structure between the hook plate 8 and the hook plate horizontal moving component and the hook plate lifting component, the hook plate 8 will not have any angular deflection; so when the flat culture medium is transferred to the narrow conveyor belt 2, the formation of the flat culture medium can also be kept neat.

[0057] The hook-and-carry plate 8 needs to be lowered until the lower edge is close to the conveyor belt surface, so that the hook-and-carry plate 8 can fully contact the side of the flat culture medium; the hook-and-carry plate 8 can push the flat culture medium onto the narrow conveyor belt 2. After the push is completed, the hook-and-carry plate 8 will rise again and return to the starting point for the next round of hooking and pushing the flat culture medium. The above actions are all completed under the action of the hook-and-carry plate lifting assembly;

[0058] The above-mentioned hook conveying plate lifting assembly is configured as an electric control push rod 7; Figure 1 As shown, in this embodiment, two electric control push rods 7 are provided; the base end of the electric control push rod 7 is provided below the electric control slider 6; and the telescopic end of the electric control push rod 7 is provided with a hooking plate 8. The extension and contraction of the electric control push rod 7 can realize the lowering or raising of the hooking plate 8. The electric control push rod 7 is an existing product that can be purchased, and the structure and control circuit of the electric control push rod 7 belong to the existing technology, which will not be described in detail here.

[0059] Example 2

[0060] Based on Example 1, in Example 1, the operation of electrically controlling the transfer of the flat culture medium from the wide conveyor belt 1 to the narrow conveyor belt 2 is realized; the continuous transfer of the flat culture medium is realized and the neat arrangement of the formation is ensured to avoid deviation during coding; the flat culture medium is moved from the wide conveyor belt 1 to the narrow conveyor belt 2 and needs to be located in the middle position of the narrow conveyor belt 2, so that the bottom surface of the flat culture medium is fully in contact with the narrow conveyor belt 2, maintaining the balance of the center of gravity and making the transmission more stable; in addition, the coding is made to be located as centered as possible on the bottom surface of the flat culture medium.

[0061] In order to ensure that the plate culture medium can stay in the center of the narrow conveyor belt 2 each time it is transferred to the narrow conveyor belt 2, as shown in FIG. Figure 2 As shown, in this embodiment, a laser rangefinder 11 is arranged above the hook plate 8; the specific arrangement structure of the laser rangefinder 11 is as follows: a supporting plate 701 is horizontally arranged on the telescopic end of the electric control push rod 7; the hook plate 8 is vertically arranged in the center below the supporting plate 701; a laser rangefinder 11 is arranged in the center above the supporting plate 701; the laser rangefinder 11 is connected to the PLC for communication, and the PLC is then connected to the electric control slider 6 for communication.

[0062] The laser emitted by the laser rangefinder 11 can be reflected after hitting the surface of the support plate 4; the distance between the laser rangefinder 11 and the support plate 4 is calculated when the hook and delivery plate 8 just pushes the flat plate culture medium to the middle position of the narrow conveyor belt 2; each time the hook and delivery plate 8 pushes the flat plate culture medium, when the laser rangefinder 11 measures that it has reached the set distance, it sends a control signal to the PLC, and the PLC controls the electronic control slider 6 to stop moving; in this way, it can be ensured that the hook and delivery plate 8 hooks the flat plate culture medium to the middle position of the narrow conveyor belt 2 every time; the flat plate culture medium can move smoothly on the narrow conveyor belt 2 and the inkjet code is exactly located at the bottom center of the flat plate culture medium.

[0063] Example 3

[0064] Based on Example 1, in Example 1, when the flat plate culture medium on the wide conveyor belt 1 moves close to the discharge side, the hooking plate 8 needs to be dropped in time and located at the rear side of the flat plate culture medium to hook and push the flat plate culture medium onto the narrow conveyor belt 2. The hooking plate 8 needs to be dropped in time to be located just at the rear side of the flat plate culture medium so that the flat plate culture medium can be pushed.

[0065] In order to make the hook plate 8 descend more accurately after the flat plate culture medium is transported to the specified position, Figure 1As shown, in this embodiment, an infrared transmitter 9 and an infrared sensing receiver 10 are respectively arranged on both sides of the wide conveyor belt 1 and close to the left side of the n-type bracket 3; the infrared transmitter 9 is arranged on one side of the wide conveyor belt 1, and the infrared sensing receiver 10 is arranged on the other side of the wide conveyor belt 1; and the infrared transmitter 9 is directly opposite to the infrared sensing receiver 10; the infrared sensing receiver 10 is connected to the PLC for communication, and the PLC is connected to the electric control push rod 7 for communication.

[0066] When the flat culture medium moves on the wide conveyor belt 1 to a position that just blocks the infrared rays of the infrared transmitter 9, the infrared sensing receiver 10 cannot receive the infrared rays normally. At this time, the infrared sensing receiver 10 sends a signal to the PLC, and the PLC controls the electric push rod 7 to move downward, so that the hooking plate 8 is located at the rear side of the flat culture medium, and begins to hook and move the flat culture medium toward the narrow conveyor belt 2.

[0067] Example 4

[0068] Based on Example 1, in Example 1, the length of the hooking and conveying plate 8 is fixed. If the length of the flat plate culture medium arranged side by side does not exceed the length of the hooking and conveying plate 8, the hooking and conveying plate 8 can normally hook and convey the flat plate culture medium; however, if the number of flat plate culture mediums arranged side by side is large, the hooking and conveying plate 8 may not be able to hook and convey the flat plate culture mediums located on both sides;

[0069] like Figure 2 As shown, in this embodiment, an extension plate 801 is provided on both sides of the hook and conveying plate 8 through a hinged joint; when the length of the hook and conveying plate 8 needs to be extended, the extension plates 801 on both sides are simply flipped over to be flush with the hook and conveying plate 8. At this time, there are extension plates 801 on both sides of the hook and conveying plate 8, which increases the overall length. When the number of flat plate culture media is large and the length of the side-by-side queue is long, hook and conveying can also be performed; if there is no need to expand the hook and conveying plate 8, the extension plates 801 on both sides are flipped over and attached to the back of the hook and conveying plate 8.

[0070] As a preferred embodiment, after the extension plate 801 is flipped over to be flush with the hooking and conveying plate 8, it needs to be fixed to the hooking and conveying plate 8; Figure 5 As shown, magnetic components are arranged on the opposite sides of the hooking plate 8 and the extension plate 801; the magnetic components are used to keep the two relatively fixedly connected after the extension plate 801 is flipped over to be flush with the hooking plate 8. The above-mentioned magnetic components include: a magnet sheet 802 and a metal sheet 803; the magnet sheet 802 is arranged on the side of the extension plate 801; the metal sheet 803 is arranged on the side of the hooking plate 8 opposite to the magnet sheet 802. In this way, when the extension plate 801 is flipped over to be flush with the hooking plate 8, the magnet sheet 802 on the side of the extension plate 801 will attract the metal sheet 803 on the side of the hooking plate 8, so that the extension plate 801 and the hooking plate 8 remain fixed.

[0071] Example 5

[0072] Based on Example 4, in Example 4, the overall length of the hook and conveying plate 8 is extended by providing extension plates 801 on both sides of the hook and conveying plate 8, and the extension plates 801 are flipped over to be flush with the hook and conveying plate 8 to achieve extension; the extension plates 801 are flipped over to the back side of the hook and conveying plate 8 to achieve folding; when the extension plates 801 are folded on the back side of the hook and conveying plate 8, the overall thickness of the hook and conveying plate 8 is increased; in addition, if the extension plates 801 are not firmly connected and fixed on the back side of the hook and conveying plate 8, the extension plates 801 will detach from the hook and conveying plate 8, causing swinging, thereby affecting the movement of the flat culture medium by the hook and conveying plate 8.

[0073] like Figure 4 As shown, a hollow sandwich structure is provided inside the two sides of the hook conveying plate 8; an extension plate 801 is slidably provided inside the hollow sandwich structure; when the hook conveying plate 8 needs to be extended, the extension plate 801 is pulled out from the sandwich structure; when the hook conveying plate 8 does not need to be extended, the extension plate 801 is pushed back into the sandwich structure. In this way, the length of the hook conveying plate 8 is extended without increasing the thickness of the hook conveying plate 8 itself.
