The applicant has applied for an intelligent microbial sample processing device [authorization publication number CN218596396U], which is used to open, inoculate, and close the lid of a flip-top loader. The lid moves with the loader throughout the inoculation process, so the device lacks a temporary storage location for the lid, making it incapable of inoculating split-type loaders. Utility Model Content

[0003] The purpose of the utility model is to solve the above problems in the existing technology and to propose an automatic inoculation device with a split loader having high working efficiency.

[0004] The purpose of this utility model can be achieved through the following technical solutions:

[0005] An automatic inoculation device for a split loader includes a frame, a water flow turntable arranged on the frame, a cover-moving module, a marking module and a packing module. A plurality of workstation slots for placing loaders are evenly arranged along the circumferential direction on the water flow turntable. The cover-moving module is used to transfer the cover of the loader into the workstation slot. The marking module is used to inoculate the sample into the loader after the cover is opened. The packing module is used to remove the loader inoculated with the sample and covered with the cover from the workstation slot. A temporary storage position is provided between any two adjacent workstation slots. When the cover is opened, the cover-moving module moves the cover to the temporary storage position.

[0006] Setting the temporary storage position on the water turntable does not occupy other space of the device, which helps to make the device more compact. At the same time, the temporary storage position is located on the side of the work station slot, which can quickly transfer the cover to the position, thereby improving work efficiency.

[0007] In the automatic inoculation device of the above-mentioned split loader, the cap removal module includes a bracket, a rotary motor vertically mounted on the bracket, a rotary seat mounted on the rotary motor's rotating shaft, a slide mounted horizontally on the rotary seat, and a translation motor for driving the slide to slide horizontally. The slide is provided with a lifting motor and a mounting block driven up and down by the lifting motor. The lower end of the mounting block is provided with a suction cup connected to the negative pressure system. When the rotary motor is in operation, it can drive the rotary seat to rotate around the rotary motor's rotating shaft. When the translation motor is in operation, it can drive the slide to move horizontally. When the lifting motor is in operation, it can drive the mounting block to move up and down. When the suction cup adsorbs the cap, the cap can be lifted up and down, moved horizontally, and rotated to meet different work requirements.

[0008] In the automatic inoculation device of the above-mentioned split loader, a guide rail is provided at the lower part of the rotating seat, a slider is provided on the sliding seat that slides with the guide rail, a guide hole extending up and down is also provided on the sliding seat, and a guide column is provided on the mounting block that slides with the guide hole.

[0009] The slide seat is guided by the provided guide rails and sliding blocks to improve stability; the installation block is guided by the guide holes and guide columns to improve stability of the installation block.

[0010] In the automatic inoculation device of the above-mentioned split loader, the workstation slot drives the loader to pass through the loading station, marking station and unloading station in sequence, the cover moving module is used to move the cover of the loader entering the loading station to the temporary storage position / on the loader at the unloading station, the marking module is used to inoculate the sample into the loader at the marking station, and the boxing module is used to move the loader at the unloading station out of the workstation slot.

[0011] When the device starts working, the first loader enters the station slot at the loading station, and then rotates step by step at an angle of 360° / N (N is the number of station slots) along the flow turntable. After completing the opening and inoculation actions in sequence, it reaches the unloading station. At this time, the Nth loader just enters the loading station. The cover transfer module can move the cover of the Nth loader directly to the first loader, reducing the number of transfers and improving work efficiency.

[0012] The cap transfer module grabs the caps from loaders 1 to N-1 and moves them to a temporary storage area. Starting from the Nth loader, the caps entering the loading station are directly moved to the loader at the unloading station. The last N-1 caps are obtained from the temporary storage area.

[0013] In the automatic inoculation device of the above-mentioned split loader, there are four work station slots.

[0014] The lids of the 1st to 3rd loaders are grabbed by the lid transfer module and taken to the temporary storage. Starting from the 4th loader, the lids entering the loading station are directly moved to the loader at the unloading station, which is equivalent to moving the lid of the 4th loader to the 1st loader, moving the lid of the 5th loader to the 2nd loader, and moving the lid of the nth loader to the n-3rd loader. The lids of the n-2nd, n-1st, and nth loaders are obtained from the temporary storage, which reduces the number of transfers of the lid transfer module and improves work efficiency.

[0015] In the automatic inoculation device with the split loader, the temporary storage position is provided with a placement groove adapted to the lid, which is used to position the lid and ensure the accuracy of the lid removal module in grabbing the lid each time.

[0016] In the automatic inoculation device of the above-mentioned split loader, a temporary storage box is provided on the side of the water turntable at the unloading station. The temporary storage box has a passage that runs through the top and bottom. The bottom of the temporary storage box is provided with a door panel that can seal the passage. The packing module moves the loader located at the unloading station to the passage of the temporary storage box.

[0017] There is a transfer box directly below the temporary storage box. The packing module moves the loader at the unloading station to the temporary storage box. When the number of loaders in the channel reaches a certain level, the door panel opens, and the loader in the temporary storage box enters the transfer box under the action of the lifting module. The door panel is closed in time to prevent a large amount of outside air from entering the transfer box.

[0018] In the automatic inoculation device of the above-mentioned split loader, a mounting plate is provided at the bottom of the temporary storage box, the channel is arranged through the mounting plate, the door panel is slidably fitted with the mounting plate, and a power structure for driving the mounting plate is provided on the mounting plate.

[0019] The door panel is slidingly arranged on the lower side of the mounting plate. The door panel moves horizontally under the action of the power structure and has two states: channel closed and channel open. When the channel is open, the loader in the channel can enter the transfer box, and when the channel is closed, the air can be isolated.

[0020] In the automatic inoculation device of the above-mentioned split loader, the power structure includes a screw rod that is rotated on the mounting plate and a motor that drives the screw rod to rotate. The mounting plate has a slot corresponding to the screw rod, and the screw rod is threaded with a nut. The door panel is fixed to the nut through a connecting block passed through the slot.

[0021] When the motor rotates, it will drive the screw to rotate. The screw and nut cooperate, and the slots limit the connecting block to prevent the connecting block from rotating.

DETAILED DESCRIPTION

[0030] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0031] like Figure 1 and Figure 2The automatic inoculation device of the split loader shown is a part of the structure of the microbial sample inoculation device, including a frame (not shown in the figure), a water turntable 1 arranged on the frame, a cover removal module 2, a marking module 3 and a packing module 4. The water turntable 1 is rotatably arranged on the frame and driven by a stepper motor 9. The cover removal module 2 can drive the negative pressure adsorption head to move in three axes in space, which is used to move the cover of the loader. The marking module 3 can drive the marking needle to move between the needle seat and the marking area. The packing module 4 can move the loader inoculated with the sample and covered with the cover from the work station slot 11 to the transfer box.

[0032] like Figure 5 As shown, the cover removal module 2 includes a bracket 21, a rotary motor 22 vertically mounted on the bracket 21, a rotating base 23 mounted on the rotating shaft of the rotary motor 22, a slide 24 horizontally mounted on the rotating base 23, and a translation motor 25 for driving the horizontal sliding of the slide 24. The slide 24 is equipped with a lifting motor 26 and a mounting block 27 driven by the lifting motor 26 to move it up and down. The lower end of the mounting block 27 is equipped with a suction cup 28 connected to the negative pressure system. To ensure stability, a guide rail 231 is provided at the lower portion of the rotating base 23, and the slide 24 is equipped with a slider 241 that slidably engages with the guide rail 231. The slide 24 is also equipped with two guide holes 242 extending vertically. The mounting block 27 is equipped with two guide posts 271 that slidably engage with the guide holes 242.

[0033] When the rotating motor 22 is working, it can drive the rotating seat 23 to rotate around the rotating shaft of the rotating motor 22. The rotating shaft of the translation motor 25 is threadedly matched with the slide 24. When the translation motor 25 is working, it can drive the slide 24 to move horizontally. The rotating shaft of the lifting motor 26 is threadedly matched with the mounting block 27. When the lifting motor 26 is working, it can drive the mounting block 27 to move up and down. After the suction cup 28 adsorbs the lid, the lid can be lifted up and down, moved horizontally and rotated, which meets different work needs while improving work efficiency.

[0034] like Figure 2 As shown, a plurality of station slots 11 for placing loaders are evenly arranged along the circumferential direction on the water flow turntable 1, and a temporary storage position is provided between any two adjacent station slots 11. When the cover is opened, the cover moving module 2 moves the cover to the temporary storage position.

[0035] The temporary storage position is set on the water flow turntable 1, which does not occupy other space of the device and helps to make the device more compact. At the same time, the temporary storage position is located on the side of the station slot 11, which can quickly transfer the lid to the position, thereby improving work efficiency.

[0036] In this embodiment, Figure 2As shown, there are four station slots 11, which drive the loader through the loading station, the first marking station, the second marking station, and the unloading station in sequence. The marking modules 3 can be arranged in one or two groups. When there are two groups of marking modules 3, each group of marking modules 3 corresponds to a marking station. A barcode printer 10 is installed above the unloading station to print information barcodes on the loader located at the unloading station.

[0037] When the device starts working, the lids of the 1st to 3rd loaders are grabbed by the lid-shifting module 2 and taken to the temporary storage. At this time, the lids can be quickly moved into place by the rotation of the lid-shifting module 2. Starting from the 4th loader, the lids entering the loading station are directly moved to the loader at the unloading station, which is equivalent to moving the lid of the 4th loader to the 1st loader and the lid of the 5th loader to the 2nd loader. The last loader is recorded as n, and the lid of the nth loader is moved to the n-3th loader. The lids of the n-2th, n-1th, and nth loaders (i.e., the last three loaders) are obtained from the temporary storage, which reduces the number of transfers of the lid-shifting module 2 and improves work efficiency.

[0038] like Figure 2 As shown, a placement groove 12 adapted to the lid is provided at the temporary storage position, and the placement groove 12 is used to position the lid to ensure the accuracy of the lid-moving module 2 in grabbing the lid each time.

[0039] like Figure 1 and Figure 2 As shown, a temporary storage box 5 is provided at the side of the water turntable 1 at the unloading station. Figure 3 and Figure 4 As shown, the temporary storage box 5 has a vertically penetrating passage 51 therein, and a door panel 6 is provided at the bottom of the temporary storage box 5 to seal the passage 51 . The packing module 4 moves the loader at the unloading station to the passage 51 of the temporary storage box 5 .

[0040] A transfer box is provided just below the temporary storage box 5. The packing module 4 moves the loader at the unloading station to the temporary storage box 5. When the number of loaders in the channel 51 reaches a certain amount, the door panel 6 opens, and the loader in the temporary storage box 5 enters the transfer box under the action of the lifting module. The door panel 6 is closed in time to prevent a large amount of outside air from entering the transfer box.

[0041] like Figure 3 and Figure 4 As shown, a mounting plate 7 is provided at the bottom of the temporary storage box 5, a channel 51 is provided through the mounting plate 7, the door panel 6 is slidably fitted with the mounting plate 7, and a power structure for driving the mounting plate 7 is provided on the mounting plate 7.

[0042] The door panel 6 is slidingly set on the lower side of the mounting plate 7. The door panel 6 moves horizontally under the action of the power structure and has two states: the channel 51 is closed and the channel 51 is open. When the channel 51 is open, the loader located in the channel 51 can enter the transfer box, and when the channel 51 is closed, the air can be isolated.

[0043] In order to better guide the door panel 6, Figure 4 As shown, a guide groove is provided on the lower surface of the mounting plate 7, and the door panel 6 is slidably fitted in the guide groove.

[0044] like Figure 3 As shown, the power structure includes a screw rod 8 rotatably arranged on the mounting plate 7 and a motor 9 that drives the screw rod 8 to rotate. The mounting plate 7 has a slot 71 corresponding to the screw rod 8. The screw rod 8 is threaded with a nut, and the door panel 6 is fixedly connected to the nut through a connecting block passed through the slot 71.

[0045] When the motor 9 rotates, it will drive the screw rod 8 to rotate. The screw rod 8 cooperates with the nut, and the slot 71 limits the connecting block to prevent the connecting block from rotating. When the screw rod 8 rotates, the movement of the nut drives the connecting block to translate, thereby realizing the translation of the door panel 6.

[0046] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
