Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a mechanical structure for automatic return of the tube after it is clamped. Background Technology

[0002] Hospitals need to draw blood from numerous patients daily for testing. Vacuum test tubes are commonly used to draw blood. These test tubes need to be transported to the laboratory's testing equipment as quickly as possible. Current test tube delivery systems only have a forward-pushing mechanism. When the vision sensor malfunctions, two tubes may come down simultaneously, easily causing jamming. Jammed tubes require manual intervention and must be handled by a maintenance engineer, increasing after-sales maintenance costs and economic expenses. Furthermore, jamming delays the delivery of subsequent test tubes, further hindering patients' treatment. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic return mechanism for tubes after jamming. This mechanism automatically resolves the problem when tube jamming occurs, eliminating the need for maintenance personnel, reducing costs, and ensuring continued normal operation even after jamming, without delaying the delivery of subsequent test tubes. It solves the problem of current test tube delivery devices that only push forward, where two tubes may simultaneously descend into the channel when the visual sensor malfunctions, easily causing jamming. Jamming requires manual intervention and a maintenance engineer, increasing after-sales maintenance costs and economic costs. Furthermore, tube jamming delays the delivery of subsequent test tubes, further hindering patient care.

[0005] (II) Technical Solution

[0006] To achieve the goals of automatically troubleshooting tube jamming without requiring maintenance personnel, reducing costs, and ensuring normal operation even after tube jamming without delaying subsequent testing, this utility model provides the following technical solution: an automatic tube return mechanism after tube jamming, comprising a platform plate, two opposing bottom support plates on the platform plate, and limit sliding plates on the bottom support plates respectively. The limit sliding plates are used to restrict and stack test tubes. A pusher is also provided between the two bottom support plates. The pusher is used to push the bottommost test tube located between the limit sliding plates. The pusher is provided with two clamping plates. When the pusher pushes away the bottommost test tube and resets it, the two clamping plates will clamp the test tube falling above and pull it away.

[0007] Preferably, a channel is formed between the limiting slide plates, and test tubes are stacked inside the channel.

[0008] Preferably, a visual sensor is provided on one side of the limiting slide plate, and the visual sensor is used to check whether there is a test tube inside the channel.

[0009] Preferably, the pusher is cylindrical, and a clamp is provided at one end of the pusher near the test tube and in the middle, forming a retention space between the clamps, which is used to catch the test tube falling from above.

[0010] Preferably, the distance between the two clamps is greater than the length of the test tube.

[0011] Preferably, a return slide plate is provided on one side of the bottom support plate. When the pusher head is reset, the test tube located in the retention space will fall into the return slide plate.

[0012] Preferably, the bottom of the platform plate is further provided with a lower base plate perpendicular to the platform plate, and the lower base plate is provided with a motor and two pulleys, with a transmission belt connecting the pulleys, and the motor is connected to one of the pulleys.

[0013] Preferably, the lower base plate is further provided with a slide rail, and a slider is slidably mounted on the slide rail.

[0014] Preferably, the bottom of the slider is fixedly connected to the transmission belt, and a connector is provided above the slider, which is fixedly connected to the push head.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a mechanical structure for automatic return of the tube after clamping, which has the following beneficial effects:

[0017] This is a mechanical structure for automatic tube return after tube jamming, achieved through the coordinated operation of its various components. Under normal conditions, the test tube slides between two limiting slide plates and falls into the channel. A vision sensor detects the test tube, and according to the programmed sequence, the pusher initiates its movement, pushing the test tube out of the current module to the next. In case of a malfunction, two or more test tubes may slide between the two limiting slide plates, leaving one test tube remaining in the channel. The cause is that the vision sensor fails to detect the test tube, preventing the pusher from moving. With two test tubes in the channel, the vision sensor detects the tube, and the pusher initiates its movement according to the programmed sequence. After pushing one test tube away, the other test tube, positioned above the pusher, falls into the retention space between the two clamping plates of the pusher. The pusher then resets, pushing the test tube back into the return limit slide plate and into the return loading hopper for reloading. This achieves automatic troubleshooting when tube jamming occurs, eliminating the need for maintenance personnel, reducing costs, and ensuring continued normal operation even after a jam, without disrupting subsequent testing processes.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 A mechanical structure for automatic return to the chamber after the tube is clamped includes a platform plate 7, which serves as the basic support component of the entire mechanical structure.

[0024] Two bottom support plates 8 are arranged opposite each other on the platform plate 7. The bottom support plates 8 are arranged in pairs on the platform plate 7 to support and position the limiting slide plate 2 and the push head 3.

[0025] The bottom support plate 8 is also equipped with limiting slide plates 2. The limiting slide plates 2 are used to restrict and stack test tubes 1, restricting the position of test tubes 1 and guiding their stacking. During normal operation of the equipment, there should be only one test tube 1 between the two limiting slide plates 2. Once a fault occurs, there will be two test tubes 1 between the two limiting slide plates 2. In this case, in order to ensure that the fault can be automatically eliminated later, the limiting slide plates 2 will guide the excess test tubes 1 to be stacked in an orderly manner between the two, ensuring accurate troubleshooting later.

[0026] A pusher 3 is also provided between the two bottom support plates 8. The size of the pusher 3 is only used to push the bottom test tube 1 located between the limit slide plates 2. When the bottom test tube 1 is pushed into the next process pusher 3 to reset, the upper test tube 1 will fall downwards without the support of the lower test tube 1. Since the pusher 3 is provided with two clamping plates 9, the two clamping plates 9 will hold the upper test tube 1 that has fallen, pull the test tube 1 away, thereby eliminating the fault and allowing the excess test tube 1 to automatically return to the chamber for re-inspection.

[0027] The limiting slide plate 2 forms a channel 5, and test tubes 1 are stacked inside the channel 5. The channel 5 provides a stacking area for test tubes 1, and also guides test tubes 1 to move in a predetermined direction, so that test tubes 1 can wait for push head 3 to operate in a neat and orderly manner, ensuring that the mechanical structure processes test tubes 1 smoothly.

[0028] A vision sensor 6 is installed on the sliding plate 2 on one side of the limit. The vision sensor 6 is used to check whether there is a test tube 1 inside the channel 5.

[0029] The pusher 3 is cylindrical, and can only push one test tube 1 into the next process at a time. The pusher 3 has clamps 9 at one end near the test tube 1 and in the middle, and the distance between the two clamps 9 is greater than the length of the test tube 1. When the pusher 3 pushes to its end and pushes one test tube 1 into the next process, the test tube 1 above loses the support of the test tube 1 below and falls downwards into the retention space 10 formed between the clamps 9, where it is limited by the clamps 9 on both sides. Subsequently, during the reset process of the pusher 3, the test tube 1 in the retention space 10 is pulled out by the clamps 9 until it reaches the return slide plate 4. The test tube 1 then falls out through the return slide plate 4 and re-enters for testing.

[0030] The bottom of the platform plate 7 is also provided with a lower base plate 17 perpendicular to the platform plate 7. The lower base plate 17 is perpendicular to the platform plate 7 and provides a mounting position for components such as the motor 11 and pulleys 12. The lower base plate 17 is equipped with the motor 11 and two pulleys 12, and a transmission belt 13 is connected between the pulleys 12. The motor 11 is connected to one of the pulleys 12. The pulleys 12, the motor 11, and the transmission belt 13 form a drive device that drives the push head 3 to reciprocate.

[0031] The bottom plate 17 is also provided with a slide rail 15, on which a slider 14 is slidably mounted. The bottom of the slider 14 is fixedly connected to the transmission belt 13. The transmission belt 13 can drive the slider 14 to reciprocate back and forth on the slide rail 15, and transmit the reciprocating motion to the push head 3 through the connector 16.

[0032] Working principle: Under normal conditions, test tube 1 slides between the two limiting slide plates 2 and falls into channel 5. The vision sensor 6 detects test tube 1, and according to the program settings, the pusher head 3 starts to move, pushing test tube 1 out of the module to the next module. In case of failure, two or more test tubes 1 may slide between the two limiting slide plates 2, leaving one test tube 1 in channel 5 that has not been pushed away. Cause analysis: The vision sensor 6 fails to detect test tube 1, causing the pusher head 3 to not move. There are two test tubes 1 in channel 5. The vision sensor 6 detects test tube 1, and according to the program settings, the pusher head 3 starts to move, pushing away one test tube 1. The other test tube 1 is above the pusher head 3. After the pusher head 3 passes, the test tube 1 above falls into the retention space 10 between the two clamping plates 9 of the pusher head 3. After the pusher head 3 resets, it pushes test tube 1 into the return limit slide plate 2, where it falls into the return loading bin for reloading. This achieves the effect of automatically eliminating faults when pipe jamming occurs, eliminating the need for maintenance personnel, reducing costs, and ensuring normal operation even after pipe jamming, without delaying the subsequent inspection process.
