Description

Technical Field

[0001] The utility model relates to the technical field of in vitro diagnosis, in particular to a gripping reaction cup structure. Background Art

[0002] The reaction cup is a container used by in vitro diagnostic instruments to transport and store samples such as blood. It is a reaction and storage container used during the testing process. When the instrument is in use, the reaction cup needs to be grabbed and transferred to facilitate sampling or testing.

[0003] In the prior art, the cuvette gripper mechanism commonly uses an electric cylinder gripper, which is not only expensive, large in size and weight, but also cannot detect whether the cuvette is successfully gripped during gripping. If the gripping is unsuccessful, the process is wasted, reducing work efficiency. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a gripping reaction cup structure, which can detect whether the gripping is successful when the reaction cup is gripped.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized by the following technical solutions: a gripping reaction cup structure, including a mounting main board, a clamping claw mechanism, an electromagnet and a sensor;

[0006] The clamp mechanism includes a clamp, a slide bar and a connecting rod. The clamp is symmetrically provided with two clamps and can be relatively horizontally moved on the mounting main board. The top of the clamp is rotatably connected with the connecting rod, and the side of the bottom close to each other is a wedge-shaped end. The connecting rod is rotatably connected with the bottom of the slide bar.

[0007] The electromagnet includes an electromagnet body and an electromagnet core. The electromagnet body is fixedly arranged on the mounting mainboard. The electromagnet core is slidably inserted in the electromagnet body. The top is connected to the electromagnet body through a spring, and the bottom is connected to the slide rod. The sensor is fixedly arranged on the mounting mainboard, and the top of the electromagnet core can be inserted into the sensor.

[0008] When working, the device moves to the top of the reaction cup, at which time the spring is in a natural state and the electromagnet is in a closed state. The upper mechanism drives the device to move downward as a whole, the bottom of the clamp contacts the reaction cup, and under the action of the wedge-shaped end, the two clamps expand to both sides, thereby clamping on both sides of the reaction cup. Then the upper mechanism drives the device to move upward as a whole, and the clamp grabs the reaction cup and moves upward. Since the reaction cup has weight, the sliding rod and the electromagnet core are pulled downward by the connecting rod, and the electromagnet core is not located in the sensor. If the reaction cup falls during the grabbing process, the spring drives the electromagnet core to reset and insert it into the sensor. After the sensor senses it, the upper mechanism can react and re-grasp the reaction cup. After being transported to the specified position, the electromagnet is energized, and the electromagnet body generates a magnetic force greater than the spring to suck the core downward. At the same time, the sliding rod moves downward to drive the clamp to open, thereby releasing the reaction cup.

[0009] The beneficial effects of the above-mentioned gripping reaction cup structure are: compared with the electric gripper, it has the advantages of lower cost, lighter weight and smaller size, and can detect whether the gripper successfully grasps the reaction cup, thereby improving work efficiency.

[0010] Furthermore, a limiting track is provided on the mounting main board, the limiting track is arranged in a horizontal direction, and is slidably connected to two sliders, and the two clamping claws are respectively arranged on the two sliders.

[0011] The limiting rail and the slider can limit the movement of the clamping jaws, so that the two clamping jaws can only move in the horizontal direction and move closer to or away from each other with the cooperation of the connecting rod.

[0012] Furthermore, a guide groove is provided on the mounting main board, the guide groove is arranged along the vertical direction, and the sliding rod is slidably connected to the guide groove.

[0013] The guide groove can limit the movement trajectory of the slide bar so that it can only move in the vertical direction.

[0014] Furthermore, a fixed adjustment block is provided on the mounting main board, and the electromagnet body is detachably connected to the fixed adjustment block.

[0015] The fixed adjustment block is used to fix the electromagnet body, and the detachable connection can facilitate the adjustment of the height position of the electromagnet body.

[0016] Furthermore, a strip-shaped through hole is provided on the fixed adjustment block, a threaded hole is provided on the side of the electromagnet body, and a bolt passing through the strip-shaped through hole is threadedly connected.

[0017] After adjusting the electromagnet body to a suitable height position, pass the bolt through the bar-shaped through hole and connect it with the threaded hole to lock the electromagnet body on the fixed adjustment block. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0028] See also Figures 1 to 3 The utility model provides a gripping reaction cup structure, including an installation main board, a clamping claw mechanism, an electromagnet and a sensor. The reaction cup is gripped by the clamping claw mechanism when gripping, and the reaction cup is released by the electromagnet when putting down. The sensor can detect whether the reaction cup is gripped successfully.

[0029] Specifically, the mounting main board 10 is used to mount the clamp mechanism, the electromagnet and the sensor 41, and is connected to the upper mechanism, which can drive the mounting main board 10 to rise and fall and move horizontally. The clamp mechanism includes a clamp 21, a slide bar 22 and a connecting rod 23. Two clamps 21 are symmetrically provided and can be relatively horizontally moved on the mounting main board 10. The top of the clamp 21 is rotatably connected with the connecting rod 23, and the side close to each other at the bottom is a wedge-shaped end. The other end of the connecting rod 23 is rotatably connected to the bottom of the slide bar 22. The electromagnet includes an electromagnet body 31 and an electromagnet core 32. The electromagnet body 31 is fixedly arranged on the mounting main board 10. The electromagnet core 32 is located above the electromagnet body 31, and a rod slidably inserted in the electromagnet body 31 is provided at the bottom. The electromagnet core 32 is connected to the electromagnet body 31 through a spring 33, and the rod at the bottom is connected to the slide bar 22. A sensor 41 fixing block 11 is provided on the top of the mounting main board 10 , and the sensor 41 is fixed on the sensor 41 fixing block 11 , and the electromagnet core 32 can be inserted into the sensor 41 .

[0030] During the grabbing process, the upper mechanism moves the mounting main board 10 to the top of the reaction cup, at which time the spring 33 is in a natural state and the electromagnet is in a closed state. The upper mechanism drives the mounting main board 10 to move downward, and the bottom of the clamping jaws 21 contacts the reaction cup. Under the action of the wedge-shaped end, the two clamping jaws 21 open to both sides, thereby clamping the reaction cup 1 on both sides. Then the upper mechanism drives the mounting main board 10 to move upward, and the clamping jaws 21 grab the reaction cup 1 and move upward. Since the reaction cup has a certain weight, the sliding rod 22 and the electromagnet core 32 are pulled downward by the connecting rod 23, and the electromagnet core 32 is not located in the sensor 41. If the reaction cup falls during the grabbing process, the spring 33 drives the electromagnet core 32 to reset, so that it is inserted into the sensor 41. After the sensor 41 senses it, it transmits a signal to the upper mechanism, and the upper mechanism can react and grab the reaction cup downward again. If the reaction cup does not fall, after being transported to the designated position, the electromagnet is energized, and the electromagnet body 31 generates a magnetic force greater than the spring 33 to suck the electromagnet core 32 downward, and at the same time the slide bar 22 moves downward to drive the clamping claw 21 to open, thereby releasing the reaction cup 1 at the designated position.

[0031] In this embodiment, the upper mechanism includes a cylinder and a horizontal transmission belt. The cylinder can drive the entire structure to rise and fall to grab the reaction cup, and the horizontal transmission belt can drive the cylinder and the entire structure to move horizontally to transfer the reaction cup.

[0032] Specifically, a limiting rail 12 and a guide groove 13 are provided on the mounting main board 10. The limiting rail 12 is arranged in the horizontal direction and is slidably connected to two sliders 121. The two clamping jaws 21 are respectively arranged on the two sliders 121. The guide groove 13 is arranged in the vertical direction, and the slide bar 22 is slidably connected to the guide groove 13. The limiting rail 12 and the slide bar 121 can limit the movement of the clamping jaws 21, so that the two clamping jaws 21 can only move in the horizontal direction, and approach or move away from each other under the cooperation of the connecting rod 23. The guide groove 13 can limit the movement trajectory of the slide bar 22, so that it can only move in the vertical direction.

[0033] Furthermore, a fixed adjustment block 14 is provided on the mounting main board 10, and the electromagnet body 31 is detachably connected to the fixed adjustment block 14. In this embodiment, a bar-shaped through hole is provided on the fixed adjustment block 14, and a threaded hole is provided on the side of the electromagnet body 31, and a bolt passing through the bar-shaped through hole is threadedly connected. The fixed adjustment block 14 is used to fix the electromagnet body 31 and facilitate the adjustment of the height of the electromagnet body 31. After the electromagnet body 31 is adjusted to a suitable height, the bolt is passed through the bar-shaped through hole and connected to the threaded hole, and the electromagnet body 31 is locked on the fixed adjustment block 14.

[0034] The working principle of the above-mentioned structure for gripping reaction cups is as follows: before grabbing the reaction cup, the upper mechanism moves the structure as a whole to the top of the reaction cup, at which time the spring 33 is in a natural state and the electromagnet is in a closed state. The upper mechanism drives the installation main board 10 to move downward, and the wedge-shaped end at the bottom of the clamp 21 contacts the reaction cup 1, and the two clamps 21 open to both sides and clamp on both sides of the reaction cup 1. Then the upper mechanism drives the installation main board 10 to move upward, and the clamp 21 grabs the reaction cup and moves upward. Since the reaction cup has a certain weight, the sliding rod 22 and the electromagnet core 32 are pulled downward through the connecting rod 23, so that the electromagnet core 32 is not located in the sensor 41. If the reaction cup falls during the grabbing process, the spring 33 is reset, driving the electromagnet core 32 to be inserted into the sensor 41. After the sensor 41 senses the insertion, it transmits a signal to the upper mechanism, and the upper mechanism can react and grab the reaction cup downward again. If the reaction cup does not fall, after being transported to the designated position, the electromagnet is energized, so that the electromagnet body 31 generates a magnetic force greater than the spring 33 to suck the electromagnet core 32 downward, thereby moving the slide bar 22 downward and driving the clamping jaw 21 to open through the connecting rod 23, thereby releasing the reaction cup 1 at the designated position.

[0035] The above-mentioned reaction cup gripping structure has the advantages of lower cost, lighter weight and smaller size compared to electric grippers, and can detect whether the grippers have successfully gripped the reaction cup, thereby improving work efficiency.
