[0024] The culture dish loading device of the utility model will be described below. Figures 1-2 The culture dish loading device of the utility model will be described below.

[0025] The utility model provides a kind of culture dish loading device, such as Figure 1 And Figure 2As shown, it comprises a base 10, a rotating disc 20, a lifting mechanism, a feeding mechanism and a culture dish rack 30. The rotating disc 20 is rotatably installed on the base 10, and the rotating disc 20 has a plurality of storage grooves 221. The culture dish rack 30 is pluggably installed in the storage groove 221, and a plurality of culture dishes can be stacked in the culture dish rack 30. The groove wall of each storage groove 221 is provided with a through hole 23, and the lifting mechanism is fixed to the base 10, and the driving end of the lifting mechanism can pass through the through hole 23 to push the culture dish. The feeding mechanism is used to move the culture dish to the next station.

[0026] In an embodiment, the base 10 is fixed to the ground by bolts, serving as the support structure of the entire culture dish feeding device. In another embodiment, the base 10 is in the form of a cabinet, and the rotating disc 20, the lifting mechanism and the culture dish rack 30 are all located above the cabinet. The bottom of the base 10 is provided with movable wheels with locking function, which facilitates the adjustment of the position of the base 10 when the work station is arranged and can lock the position after moving into place.

[0027] As shown in Figure 1 and Figure 2 , the base 10 is fixedly connected with a rotary drive 40, and the driving shaft of the rotary drive 40 is in transmission connection with the rotating disc 20. Under the driving of the rotary drive 40, the rotating disc 20 can rotate relative to the base 10, so that different storage grooves 221 on the rotating disc 20 are rotated to the feeding position respectively. The size of the storage groove 221 is comparable to that of the culture dish rack 30, and the culture dish rack 30 is positioned in the storage groove 221 by means of the groove wall of the storage groove 221. The culture dish rack 30 has a relatively high height in the vertical direction, and the culture dishes can be stacked in the culture dish rack 30 in the vertical direction. Therefore, a plurality of culture dishes can be stacked in one storage groove 221 by means of the culture dish rack 30. In use, the culture dish rack 30 is fed at another place, and then the entire culture dish rack 30 is positioned in the storage groove 221, so that a plurality of culture dishes can be fed at one time.

[0028] The depth of the groove body of the storage groove 221 is not higher than the thickness of one culture dish, so as to avoid that the storage groove 221 blocks the culture dish located at the bottom. In order to improve the stability of the culture dish rack 30 in the storage groove 221, the groove opening of the storage groove 221 is provided with a guard rod which is vertically erected, providing auxiliary support for the stacked culture dishes. The groove bottom of the storage groove 221 is provided with a through hole 23 for the driving end of the lifting mechanism to drive the culture dish to move upward.

[0029] In an embodiment, the feeding mechanism is a retractable clamping mechanism which can move linearly. In use, the clamping mechanism moves forward to clamp the culture dish, and then moves backward to move the clamped culture dish to the target position and then releases it, so that the culture dish falls on the conveying belt. In another embodiment, the feeding mechanism comprises a feeding mechanical arm which picks up the culture dish from the top of the culture dish rack 30 and moves the culture dish to the next station through the movement of the feeding mechanical arm.

[0030] The lifting mechanism is arranged on the base 10, and the rotation of the rotating disc 20 can move different storage grooves 221 above the lifting mechanism. Thus, the culture dishes in multiple storage grooves 221 can be lifted by a single lifting mechanism. As the culture dishes are removed, the height of the stacked culture dishes in the culture dish rack 30 gradually decreases. To achieve point picking, the lifting mechanism moves up by a preset distance after a culture dish is removed, and the next culture dish is lifted to the unloading height, thereby repeating the cycle to move the stacked culture dishes in the culture dish rack 30 to the target height one by one. After all the culture dishes in the culture dish rack 30 are removed, the rotating disc 20 rotates to move the culture dish rack 30 placed in the next storage groove 221 to the position, and waits for unloading. At this time, the empty culture dish rack 30 is taken out from the storage groove 221 and placed in the culture dish rack 30 full of culture dishes. Thus, the process is seamlessly connected, and the loading efficiency is improved.

[0031] The culture dish loading device provided by the embodiment of the utility model, the rotating disc 20 is equipped with a storage groove 221, the culture dish rack 30 is placed in the storage groove 221, multiple culture dishes can be stacked in the culture dish rack 30, with the rotation of the rotating disc 20, the culture dish rack 30 stacked with culture dishes can be moved to the target position one by one, and the culture dishes are lifted to the target height by the lifting mechanism, thus the loading mechanism can pick the culture dishes at the fixed point, and the loading and picking efficiency of the culture dishes is improved.

[0032] In a specific embodiment, as shown in Figure 1 The rotating disc 20 includes a disc body 21 and multiple storage seats 22, each storage seat 22 is detachably installed on the disc body 21, and each storage seat 22 is equipped with a storage groove 221.

[0033] The driving end of the rotating driving part 40 is fixedly connected with the disc body 21. Under the driving of the rotating driving part 40, the disc body 21 can rotate, thereby driving the storage seat 22 to rotate. The storage seat 22 is circumferentially arranged around the rotating shaft of the rotating disc 20. The storage seat 22 is detachably installed on the disc body 21 by bolts. During the debugging of the work station, the storage seat 22 with an appropriate size can be selected according to the size of the culture dishes and installed on the disc body 21. During use, if the specifications of the culture dishes change, the storage seat 22 can be detached and replaced, and the structure is more flexible. Of course, the storage seat 22 and the disc body 21 can also be an integral structure.

[0034] As shown in Figure 1 Specifically, the edge of the disc body 21 has multiple first notches, the storage seat 22 has a second notch, and the first notches and the second notch correspond and communicate to form a through hole 23.

[0035] The first notch and the second notch are both V-shaped. The plurality of first notches are arranged at the edge of the disc body 21, and the second notches arranged on the storage seat 22 are arranged one by one corresponding to the plurality of first notches, and the first notch and the second notch are communicated to form a V-shaped through hole 23. The driving end of the jacking mechanism can jack the culture dish along the through hole 23. In addition, the arrangement mode of the first notch and the second notch can also reduce the consumption of the disc body 21 and the storage seat 22, and reduce the cost.

[0036] The through hole 23 penetrates the center of the storage groove 221. Therefore, the jacking mechanism can jack the culture dish up and down along the center of the storage groove 221, improving the stability of the culture dish moving up. Specifically, the V-shaped bottom of the first notch and the V-shaped bottom of the second notch are both circular arcs, and the center of the circular arc is coaxial with the center axis of the storage groove 221.

[0037] The storage seat 22 is provided with a plurality of guard rods around the slot of the storage groove 221. Specifically, the guard rod is arranged on the storage seat 22 and located in the slot of the storage groove 221. Optionally, the guard rod is a circular rod which is tangent to the groove wall of the storage groove 221, so that after the culture dish rack 30 is placed in the storage groove 221, the guard rod can provide support and protection for the culture dish. The height of the guard rod is greater than the height of a single culture dish, thereby providing support for the positioning of the bottom culture dish.

[0038] In addition, the storage groove 221 is provided with a plurality of limiting columns 24. As shown in Figure 1 The limiting column 24 is protruded on the groove wall of the storage groove 221. The edge of the culture dish rack 30 is provided with a limiting groove. During the process of placing the culture dish rack 30 into the storage groove 221, the limiting column 24 corresponds to the limiting groove, and the guiding is provided by the limiting column 24, so that the center of the culture dish rack 30 can correspond to the center of the through hole 23.

[0039] Optionally, the feeding mechanism includes a feeding mechanical arm and a feeding detection sensor, and the feeding detection sensor is used to detect whether the culture dish reaches the unloading position, and the feeding mechanical arm picks up the culture dish based on the detection value of the feeding detection sensor.

[0040] The feeding mechanical arm is a six-axis mechanical arm with high freedom of movement. The feeding detection sensor detects whether there is a culture dish in the unloading position, and in the case of confirming the culture dish, the feeding mechanical arm clamps and moves the culture dish to the next station. The jacking mechanism jacks according to the detection value of the feeding detection sensor. Specifically, after the culture dish is taken away by the feeding mechanical arm, the feeding detection sensor detects that there is no culture dish, at this time the jacking mechanism jacks upward by a preset distance, and the next culture dish is jacked to the unloading position. When the feeding detection sensor signal changes and it is determined that there is a culture dish, the feeding mechanical arm moves to the unloading position to pick up again.

[0041] If the lifting mechanism lifts a preset distance and the to-material detection sensor does not detect the culture dish, it indicates that the culture dishes in the culture dish rack 30 are all picked up. At this time, the turntable 20 rotates according to the detection signal of the to-material detection sensor to move the next culture dish rack 30 above the lifting mechanism. In this way, the cooperation between the rotation of the turntable 20, the lifting of the lifting mechanism and the feeding mechanical arm can be realized by means of one to-material detection sensor, and the structure is simple.

[0042] Optionally, the culture dish feeding device further comprises an alarm, which is in communication connection with the to-material detection sensor. In the case that no culture dish is determined on the turntable 20, the alarm gives an alarm to remind the operator to feed in time. Specifically, after it is determined that the culture dishes on the current culture dish rack 30 are picked up based on the to-material detection sensor, the turntable 20 rotates to move the adjacent storage groove 221 above the lifting mechanism. At this time, if the to-material detection sensor does not detect the culture dish, it indicates that there is no culture dish rack 30 in the storage groove 221. At this time, the alarm gives an alarm. Optionally, the alarm is an indicator light, an audible and visual alarm device, etc.

[0043] In a specific embodiment, the lifting mechanism comprises a lifting drive and a top plate. The lifting drive is fixed to the base 10, and the top plate is fixed to the driving end of the lifting drive. The top plate is provided with a buffer pad.

[0044] The lifting drive is fixed to the base 10 and is arranged close to the starting end of the conveying belt. Optionally, the lifting drive is a pneumatic cylinder or a linear push rod. After the top plate moves up, it contacts the bottom of the culture dish to lift the culture dish upward, so that the culture dish located at the top is moved to the discharging position, facilitating the feeding mechanical arm to pick up the culture dish at a fixed point. The top plate is a circular plate to ensure that it can contact the culture dish located at the bottom under the action of the lifting drive.

[0045] The feeding mechanical arm picks up the culture dish from the top. After one culture dish is removed, the lifting drive drives the top plate to rise by a preset distance, and then the feeding mechanical arm picks up the next culture dish at a fixed point. After all the culture dishes in the storage groove 221 are picked up, the lifting drive is reset to avoid hindering the rotation of the turntable 20. Subsequently, the turntable 20 rotates to move the culture dishes stored in the next storage groove 221 to the discharging position to be picked up by the feeding mechanical arm. In this way, the lifting drive and the turntable 20 cooperate to complete the continuous supply of culture dishes, improving the feeding efficiency.

[0046] Optionally, the buffer pad is a silica gel pad, and the silica gel pad covers the top surface of the top plate. Under the driving of the lifting driving element, the top plate moves upward to lift the culture upward, and the buffer pad contacts the lowermost culture dish to avoid damaging the culture dish during the lifting process by virtue of the flexibility of the buffer pad. Alternatively, the buffer pad includes a plurality of silica gel blocks, and the plurality of silica gel blocks are fixed on the top plate and are circumferentially arranged around the circumference of the top plate. Specifically, there are three silica gel blocks, and the three silica gel blocks define a support surface. When the top plate pushes the lowermost culture dish under the action of the lifting driving element, the silica gel blocks first contact the culture dish. To avoid the top of the plurality of silica gel blocks not being coplanar due to manufacturing errors, the top of the silica gel block is spherical. When the silica gel block contacts the culture dish, the top of the silica gel block is tangent to the bottom surface of the culture dish, so that the three silica gel blocks can accurately define a plane to avoid the culture dish tilting and shaking during the pushing process.

[0047] Specifically, as shown in Figure 1 and Figure 2 Figure 2 The culture dish rack 30 has a bottom plate and a plurality of vertical rods 31, and the plurality of vertical rods 31 are installed at intervals around the circumference of the bottom plate. The bottom plate has a through hole for the driving end of the lifting mechanism to pass through, and the through hole is in communication with the through hole 23.

[0048] The size of the bottom plate is comparable to the size of the storage slot 221, so that the bottom plate can smoothly enter and exit the storage slot 221. The bottom plate is a bottom support structure for stacked culture dishes, and the vertical rods 31 are arranged at intervals around the circumference of the bottom plate to provide vertical side support for the stacked culture dishes. In an embodiment, the culture dish rack 30 has no top plate, and the loading robot arm can pick up the culture dishes from above. In another embodiment, the top of the culture dish rack 30 has a top plate. One end of some of the vertical rods 31 is fixedly connected to the top plate, and the other end is fixedly connected to the bottom plate. The other vertical rods 31 are telescopic rods, the bottom ends of which are fixedly connected to the bottom plate, and the top ends are in abutment with the top plate. The opening formed by the telescopic rod after shortening can allow the culture dishes to be moved out from the side. When the culture dish rack 30 with stacked culture dishes is moved, the top of the telescopic rod is in abutment with the top plate to prevent the culture dishes from falling out. After the culture dish rack 30 is moved to the unloading position, the telescopic rod is shortened, and a gap is formed between the telescopic rod and the top plate, so that the culture dishes can be unloaded from the side. The gap between the telescopic rod and the top plate is greater than the height of one culture dish and less than the height of two culture dishes.

[0049] To ensure smooth lifting of the lifting mechanism, a through hole is provided in the center of the bottom plate, and the driving end of the lifting mechanism can pass through the through hole to lift the culture dishes. The through hole can also reduce the weight of the bottom plate and reduce material consumption.

[0050] The utility model also provides a kind of microbial detection work station, it includes conveying belt and the culture dish loading device as described above, and the culture dish loading device is located at the start end of conveying belt.

[0051] In the microbial detection work station, the culture dish feeding device is located at the starting end of the conveying belt, and after the culture dish is transferred to the conveying belt, it is moved to the next operation station by the conveying of the conveying belt.

[0052] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
