Technical Field
[0001] This utility model relates to the field of petri dish production technology, specifically to a three-station turntable carrier for an integrated petri dish removal and capping device. Background Technology
[0002] Petri dishes are basic experimental consumables commonly used in microbial culture, biological experiments, and cell growth. They mainly consist of a transparent plastic or glass base and a matching lid. To meet the requirements of high-volume, high-cleanliness production, petri dishes are mostly injection molded and then assembled and packaged by automated equipment.
[0003] In the current automated production of petri dishes, after the bottom and lid are injection molded, they need to undergo multiple processes such as automatic removal, positioning, and fastening to achieve the assembly of the entire dish. However, after the automatic fastening of the bottom and lid is completed, how to efficiently and stably transfer the petri dishes with the lids on in an orderly manner has become one of the key issues restricting the improvement of the overall production line efficiency.
[0004] Existing transfer structures mostly use traditional linear conveyor belts or single conveyor platforms for handling, which have technical defects such as insufficient positioning accuracy, mismatched transfer cycle, and unstable transition connections. Especially in application scenarios with multiple workstations and limited space layout, it is difficult to achieve accurate transition and reliable support of culture dishes between multiple workstations, which can easily lead to problems such as culture dishes shifting, slipping, or stacking disorder, affecting the continuity and stability of the overall assembly line. Utility Model Content
[0005] To address the aforementioned issues, a three-station turntable carrier integrating a petri dish removal and capping device is provided. By offering a multi-station turntable carrier device with a compact structure, efficient station switching, and accurate limiting function, this solves the technical problems of insufficient positioning accuracy, mismatched transfer cycle, and unstable transition connection in existing transfer equipment.

The carrier includes: a frame; a transfer module horizontally mounted on the frame; the transfer module having a turntable for transferring capped petri dishes; a transfer module vertically fixed on the frame, the transfer module having a suction unit for clamping petri dishes on the turntable and a drive unit for moving the suction unit; and a conveying module horizontally mounted on one side of the transfer module, the conveying module having a first conveying unit and a second conveying unit for transporting petri dishes; the first and second conveying units are horizontally positioned opposite each other on both sides of the transfer module.

[0028] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.
[0029] See Figures 1 to 8The diagram shows a three-station turntable carrier for an integrated petri dish removal and capping device, used for transferring capped petri dishes. It includes: a frame 1; a transfer module 2, horizontally mounted on the frame 1; the transfer module 2 having a turntable 21 for transferring capped petri dishes; a transfer module 3, vertically fixed on the frame 1, having a suction unit 31 for clamping petri dishes on the turntable 21 and a drive unit 32 for moving the suction unit 31; and a conveying module 4, horizontally mounted on one side of the transfer module 3, having a first conveying unit 41 and a second conveying unit 42 for transporting petri dishes; the first and second conveying units 41 and 42 are horizontally positioned opposite each other on either side of the transfer module 3.
[0030] During the automated transfer of culture dishes, an external power source is first connected to activate the drive unit 32. The drive unit 32 moves the suction unit 31 horizontally toward the culture dish to be transferred, positioned precisely above the target culture dish. Subsequently, the drive unit 32 continues to operate, causing the suction unit 31 to descend vertically, ensuring precise contact between the suction unit 31 and the target culture dish, and achieving stable clamping. After clamping, the drive unit 32 restarts, causing the suction unit 31 to slide along its original horizontal path toward the first transfer unit 41, moving it to its designated placement position above it.
[0031] At this time, the drive unit 32 controls the suction unit 31 to slowly descend vertically, so that the culture dish is stably placed on the first transfer unit 41 and the release action is completed, thereby realizing the automatic and precise transfer of the culture dish from the rotary table 21 to the first transfer unit 41. In order to adapt to the multi-line production mode, a second transfer unit 42 with the same structure as the first transfer unit 41 is also provided, which is used for backup transfer channel, defective product rejection channel or peak production capacity dual-line parallel output, ensuring the flexibility of the overall production process.
[0032] The multi-axis driven suction unit 31 enables precise gripping and transfer of culture dishes, with advantages such as controllable path, high positioning accuracy, and strong gripping stability. At the same time, the dual-channel design can not only remove defective products, but also adapt to the needs of high load and continuous operation of multiple lines.
[0033] The first transmission unit 41 is specifically a synchronous belt conveyor; the synchronous belt conveyor is used to directionally transport the culture dish that has been adsorbed and transferred via the transfer module 3.
[0034] See Figure 8As shown: The adsorption unit 31 is provided with a mounting frame 311 that can be longitudinally close to the culture dish, a plurality of clamping elements 312 that are vertically fixed to the bottom of the mounting frame 311, and adsorption elements 313 that are vertically arranged in the plurality of clamping elements 312.
[0035] When a culture dish on the rotary table 21 needs to be clamped and transferred, the drive unit 32 first activates, moving the suction unit 31 horizontally to a position directly above the target culture dish. Then, under the control of the drive unit 32, the suction unit 31 descends vertically towards the clamped culture dish on the rotary table 21. When the suction unit 31 approaches the top of the culture dish, the adsorption element 313 at the bottom of the suction unit 31 first makes precise contact with the upper surface of the culture dish lid. After moving down to the set adsorption stroke, it automatically activates the negative pressure adsorption function, achieving initial stable adsorption of the culture dish lid. Next, the clamping element 312 clamps the culture dish to enhance its overall stability. After completing the adsorption and clamping actions, the drive unit 32 activates again, driving the suction unit 31 horizontally to the target transfer station, and then descends vertically to accurately place the culture dish into the corresponding transfer unit. This completes the high-precision automatic clamping and adsorption transfer operation of the culture dish.
[0036] See Figure 7 As shown: The adsorption element 313 is provided with a suction cup 3131 and a guide rod 3132 that can guide the suction cup 3131 to slide longitudinally, as well as a first nut 3133 and a second nut 3134 that can limit and adjust the sliding stroke of the guide rod 3132; the first nut 3133 and the second nut 3134 are screwed together at intervals on the outside of the guide rod 3132; the first nut 3133 is located near the top of the guide rod 3132, and the second nut 3134 is located near the bottom of the guide rod 3132.
[0037] In the non-adsorption state, the suction cup 3131 assembly is suspended vertically towards the ground under its own weight via the guide rod 3132. The first nut 3133 on its upper part forms an initial limiting contact with the upper surface of the mounting bracket 311, thereby limiting the upper limit position of the suction cup 3131. When the drive unit 32 is activated, it drives the suction cup 3131 to move longitudinally downward along the direction of the guide rod 3132. The suction cup 3131 will move downward from the first stroke position (i.e., the position where the first nut 3133 contacts the mounting bracket 311) to the second stroke position (i.e., the position where the second nut 3134 abuts against the lower surface of the mounting bracket 311). When the suction cup 3131 moves down to the preset second stroke position, it means that the suction cup 3131 has accurately reached the designed adsorption depth. At this time, the suction cup 3131 automatically activates the negative pressure suction to realize the adsorption and fixation operation on the upper surface of the culture dish below. The adsorption process uses the first nut 3133 and the second nut 3134 to precisely control the upper and lower limits of the vertical stroke of the suction cup 3131 in both directions, ensuring accurate adsorption position and stable stroke, free from external mechanical interference.
[0038] By setting the first nut 3133 and the second nut 3134 to form a controllable vertical stroke range of the suction cup 3131, it is ensured that the suction cup 3131 has a clear starting point and ending point before adsorption, thereby achieving consistency and stability of the adsorption position in the culture dish; at the same time, it avoids adsorption failure caused by excessive stroke of the suction cup 3131 or insufficient adsorption depth.
[0039] See Figure 7 As shown: The adsorption element 313 further includes a sensor 3135 that can detect in real time when the guide rod 3132 moves to the adsorption position; the sensor 3135 is fixedly mounted horizontally on the mounting bracket 311 by a fixing bracket and the sensing end is set facing the guide rod 3132.
[0040] In the non-adsorption state, the suction cup 3131 is naturally suspended at the first stroke position under its own weight, in an initial preparation state before contacting the object to be adsorbed. When adsorption is required, the drive unit 32 is activated, driving the suction cup 3131 to continue moving downwards along the guide rod 3132. As the suction cup 3131 gradually contacts the upper surface of the culture dish, the guide rod 3132 also moves downwards from the first stroke position to the second stroke position. During this process, the displacement state of the guide rod 3132 is sensed in real time by the stroke sensor 3135 located near the guide path. Once the detection signal confirms that the suction cup 3131 has reached the preset adsorption height, the control system immediately drives the suction cup 3131 to generate negative pressure, completing the stable adsorption operation on the culture dish. At the same time, the clamping element 312 also operates synchronously under the command of the control system, clamping and securing the outer walls on both sides of the culture dish to achieve double fixation of the culture dish, improving clamping stability and anti-interference ability.
[0041] By combining the stroke of the suction cup 3131 with the design of the guide rod 3132 and the sensor 3135, precise control and feedback judgment of the adsorption height are achieved, ensuring that the suction cup 3131 only starts the adsorption action when it is moved to the target adsorption position, avoiding accidental adsorption or positional deviation; at the same time, the synchronous clamping operation of the clamping element 312 significantly improves the gripping stability of the culture dish and the safety and reliability of the automated operation of the equipment.
[0042] See Figure 5 As shown: The drive unit 32 is provided with a linear driver 321 that can drive the mounting bracket 311 to move longitudinally, a first rotary driver 322 that can drive the linear driver 321 to swing circumferentially, and a swing arm 323 that can drive the first rotary driver 322 to swing horizontally.
[0043] The drive unit 32 further includes a support frame 325 and a second rotary driver 324 capable of driving the swing arm 323 to swing; the second rotary driver 324 is fixedly mounted vertically on the frame 1 via the support frame 325; the proximal end of the swing arm 323 is connected to the drive end of the second rotary driver 324, and the first rotary driver 322 is fixedly mounted vertically on the distal end of the swing arm 323; the linear driver 321 is fixedly mounted vertically on the drive end of the first rotary driver 322.
[0044] When the culture dish, fixed by the adsorption unit 31, needs to be transferred to the first transfer unit 41 for further processing, an external power supply is first connected to drive the second rotary actuator 324, thereby causing the swing arm 323 mounted on it to swing horizontally around a preset rotation axis, achieving initial adjustment of the overall position of the adsorption unit 31. Subsequently, the first rotary actuator 322 is activated, further driving the linear actuator 321 connected to it to swing horizontally around its own axis for adjustment, thereby achieving precise angle correction of the adsorption end of the adsorption unit 31, ensuring that the posture of the culture dish during the subsequent release process is consistent with the placement requirements of the first transfer unit 41.
[0045] After the adsorption angle of the adsorption unit 31 is adjusted to the matching position, the culture dish is stably grasped by negative pressure adsorption. Next, the first rotary actuator 322 and the second rotary actuator 324 are driven in opposite directions to coordinate the horizontal circumferential rotation of the mounting bracket where the adsorption unit 31 is located, aligning it with the first transfer unit 41 at a preset angle. Finally, by controlling the vertical downward pressing action of the linear actuator 321, the adsorbed culture dish is accurately released and placed on the first transfer unit 41.
[0046] Through the multi-axis linkage between the first rotary driver 322, the second rotary driver 324 and the swing arm 323, the suction unit 31 can achieve multi-angle, highly controllable horizontal circumferential swing adjustment capability in a confined space, which significantly improves the flexible transfer efficiency of the culture dish between different work stations.
[0047] See Figure 7 and Figure 8 As shown: The clamping element 312 consists of a finger cylinder 3121 and a first clamp 3122 and a second clamp 3123 respectively fixedly disposed at the two clamping ends of the finger cylinder 3121.
[0048] When it is necessary to clamp the culture dish after it has been adsorbed by the adsorption element 313, simply drive the finger cylinder 3121 to move, causing the two drive ends of the finger cylinder 3121 to contract synchronously. During the contraction process, the first clamp 3122 and the second clamp 3123 are driven to move closer to each other, thus achieving simultaneous clamping of the culture dish on both sides.
[0049] This utility model not only enables efficient transport of culture dishes with a high and stable transport cycle, but also allows for multi-station transport without spatial limitations.
[0050] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
