Description

Technical Field

[0001] This utility model relates to the technical field of self-controlled nitrogen blowing concentration devices, specifically to mechanical grippers for self-controlled nitrogen blowing concentration devices. Background Technology

[0002] An automated nitrogen blowing concentrator is an automated device used for laboratory sample pretreatment, primarily for the rapid and controllable concentration of liquid samples (such as extracts, digests, and solvents). It accelerates solvent evaporation by blowing an inert gas (usually nitrogen) onto the sample surface, while an automated control system precisely regulates parameters such as temperature, gas flow rate, and time to achieve a highly efficient and safe concentration process. Mechanical grippers hold the test tubes and transfer them from the nitrogen blowing device to the liquid addition device or a temporary storage station, enabling fully automated operation.

[0003] After high-temperature nitrogen blowing, the test tubes are rapidly cooled, increasing the material's brittleness. This can cause breakage when gripped by mechanical clamps. Additionally, some low-quality test tubes may also break during the clamping process. Test tube breakage can lead to personal injury or increase the risk of equipment damage. Therefore, a mechanical clamp based on a self-controlled nitrogen blowing concentration device is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a mechanical gripper for a self-controlled nitrogen blowing concentration device, thereby solving the problems mentioned in the background art. To solve the above-mentioned technical problems, this invention is achieved through the following technical solution:

[0005] This utility model relates to a mechanical gripper for a self-controlled nitrogen blowing concentration device, comprising:

[0006] The mechanical gripper includes a first hydraulic rod, a fixed plate, a connecting plate, an arc-shaped clamping plate, and a connector. The fixed plate is fixed to the side of the cylinder of the first hydraulic rod, the connecting plate is fixed to the piston rod of the first hydraulic rod, and the arc-shaped clamping plate is rotatably connected to the first hydraulic rod through the connector.

[0007] The damage prevention component includes a first support plate, a limiting hole, a second support plate, a limiting rod, and a U-shaped protective cover. One end of the first support plate is fixed to the upper end of the first hydraulic rod cylinder, the limiting hole is opened at the other end of the first support plate, the limiting rod is inserted into the limiting hole, the second support plate is fixed to the upper end of the limiting rod, and the U-shaped protective cover is fixed to the lower end of the second support plate.

[0008] Furthermore, the damage prevention component also includes mounting holes and a first reinforcing plate. The mounting holes are opened at one end of the first support plate and are fixed to the upper end of the first hydraulic rod cylinder by bolts. The first reinforcing plate is fixed to both sides of the lower end of the first support plate.

[0009] Furthermore, the U-shaped protective cover is wrapped around the outside of the arc-shaped clamp and is movably connected to the outside of the first support plate.

[0010] Furthermore, the connector includes a first link and a second link. One end of the first link is rotatably connected to one end of the connecting plate, and the other end is rotatably connected to the middle of the second link. The end of the second link away from the arc-shaped clamp is rotatably connected to the fixed plate.

[0011] Furthermore, it also includes a spill prevention component, which includes an opening and a receiving box. The opening is located at the lower end of the U-shaped protective cover, and the receiving box is movably connected in the opening.

[0012] Furthermore, the anti-spray assembly also includes a sensor, a Z-shaped support plate, and a second hydraulic rod. The sensor is fixed to the upper inner side of the U-shaped protective cover, one end of the Z-shaped support plate is fixed to the outer side of the U-shaped protective cover, and the cylinder of the second hydraulic rod is fixed to the other end of the Z-shaped support plate.

[0013] Furthermore, the anti-splash assembly also includes a second reinforcing plate and a silicone pad, with the second reinforcing plate fixed to both ends of the Z-shaped support plate and the silicone pad placed inside the receiving box.

[0014] This utility model has the following beneficial effects:

[0015] This invention utilizes a damage prevention component. A first hydraulic rod, via an external robotic arm, moves to the test tube and downwards. As the arc-shaped clamping plate moves downwards, the U-shaped protective cover touches the worktable and is pushed upwards, causing a limiting rod to move along a limiting hole on the first support plate. This, in turn, causes the second support plate and the U-shaped protective cover to move upwards. When the arc-shaped clamping plate reaches the upper side of the test tube, the first hydraulic rod activates, the piston rod retracts, and the connecting piece on the connecting plate rotates, causing the arc-shaped clamping plate to clamp the test tube. Subsequently, the first hydraulic rod moves upwards, causing the test tube to move upwards, while the U-shaped protective cover falls under gravity until the second support plate adheres to the first support plate. At this point, the U-shaped protective cover covers the outside of the test tube. This design reduces the amplitude of liquid splashing when the test tube breaks, minimizing injury to personnel and reducing the extent of equipment damage. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-4 As shown, this utility model is a mechanical gripper for a self-controlled nitrogen blowing concentration device, comprising:

[0027] The mechanical gripper includes a first hydraulic rod 10, a fixed plate 11, a connecting plate 12, an arc-shaped clamping plate 15, and a connector. The fixed plate 11 is fixed to the side of the cylinder of the first hydraulic rod 10, the connecting plate 12 is fixed to the piston rod of the first hydraulic rod 10, and the arc-shaped clamping plate 15 is rotatably connected to the first hydraulic rod 10 through the connector.

[0028] The connector includes a first link 13 and a second link 14. One end of the first link 13 is rotatably connected to one end of the connecting plate 12, and the other end is rotatably connected to the middle of the second link 14. The end of the second link 14 away from the arc-shaped clamp 15 is rotatably connected to the fixed plate 11.

[0029] The first hydraulic rod 10 can change position and is controlled by an external hydraulic system. The model is HYDRO-LINE HLA-25. The fixing plate 11 provides support and is used to connect the second connecting rod 14. The connecting plate 12 is used to connect the first connecting rod 13. The first connecting rod 13 is used to connect the connecting plate 12 and the second connecting rod 14. The arc-shaped clamping plate 15 is used to clamp the test tube and has an anti-slip pad installed inside, which has an anti-slip function and can reduce wear on the test tube.

[0030] The damage prevention component includes a first support plate 20, a limiting hole 23, a second support plate 24, a limiting rod 25, and a U-shaped protective cover 26. One end of the first support plate 20 is fixed to the upper end of the cylinder of the first hydraulic rod 10. The limiting hole 23 is opened at the other end of the first support plate 20. The limiting rod 25 is inserted into the limiting hole 23. The second support plate 24 is fixed to the upper end of the limiting rod 25. The U-shaped protective cover 26 is fixed to the lower end of the second support plate 24.

[0031] The damage prevention component also includes a mounting hole 21 and a first reinforcing plate 22. The mounting hole 21 is opened at one end of the first support plate 20 and is fixed to the upper end of the cylinder of the first hydraulic rod 10 by bolts. The first reinforcing plate 22 is fixed to both sides of the lower end of the first support plate 20.

[0032] The U-shaped protective cover 26 is wrapped around the outside of the arc-shaped clamp 15 and is movably connected to the outside of the first support plate 20.

[0033] The first support plate 20 provides support, the mounting hole 21 provides connection, the first reinforcing plate 22 provides reinforcement, the limiting hole 23 provides limiting, and the second support plate 24 is used to connect the limiting rod 25 and the U-shaped protective cover 26. The limiting rod 25 provides connection, and the U-shaped protective cover 26 provides protection. It is made of transparent acrylic material.

[0034] Working principle:

[0035] Mounting hole 21 of first support plate 20 is fitted onto bolt on cylinder body of first hydraulic rod 10, and nut is tightened. First hydraulic rod 10 moves to test tube via external robotic arm and moves downward. As arc clamp 15 moves downward, U-shaped protective cover 26 touches workbench and is pushed upward, causing limit rod 25 to move along limit hole 23 on first support plate 20, causing second support plate 24 and U-shaped protective cover 26 to move upward. When arc clamp 15 moves to the upper side of test tube, first hydraulic rod 10 starts, piston rod retracts, causing connector on connecting plate 12 to rotate, causing arc clamp 15 to clamp test tube. Then first hydraulic rod 10 moves upward, causing test tube to move upward, while U-shaped protective cover 26 falls under gravity until second support plate 24 fits against first support plate 20. At this time, U-shaped protective cover 26 wraps around the outside of test tube.

[0036] This step can reduce the amount of test tube and liquid splashing when the test tube breaks, thereby reducing injury to personnel and minimizing the scope of equipment damage.

[0037] Please see Figure 4-5 As shown, this embodiment, based on the above embodiment, further includes:

[0038] The anti-splash assembly includes an opening 31 and a receiving box 35. The opening 31 is located at the lower end of the U-shaped protective cover 26, and the receiving box 35 is movably connected in the opening 31.

[0039] The anti-spray assembly also includes a sensor 30, a Z-shaped support plate 32, and a second hydraulic rod 34. The sensor 30 is fixed to the upper inner side of the U-shaped protective cover 26, one end of the Z-shaped support plate 32 is fixed to the outer side of the U-shaped protective cover 26, and the cylinder of the second hydraulic rod 34 is fixed to the other end of the Z-shaped support plate 32.

[0040] The anti-splash assembly also includes a second reinforcing plate 33 and a silicone pad 36. The second reinforcing plate 33 is fixed to both ends of the Z-shaped support plate 32, and the silicone pad 36 is placed inside the receiving box 35.

[0041] Sensor 30, model EE-SX1061, is used to sense whether the arc-shaped clamping plate 15 is holding the test tube. Opening 31 facilitates the movement of the receiving box 35. Z-shaped support plate 32 provides support, second reinforcing plate 33 provides reinforcement, and second hydraulic rod 34 can realize position change through external hydraulic system control. Model HYDRO-LINE HLA-16. Receiving box 35 is used to receive the falling test tube and liquid, and silicone pad 36 can absorb the energy of the falling test tube.

[0042] Working principle:

[0043] When the arc-shaped clamp 15 clamps the test tube and moves upward, the U-shaped protective cover 26 falls under its own gravity. When the sensor 30 senses the test tube on the arc-shaped clamp 15, it transmits the signal to the control system. The control system activates the second hydraulic rod 34. The piston rod of the second hydraulic rod 34 extends, driving the receiving box 35 to move along the opening 31. The receiving box 35 and the silicone pad 36 move to the bottom of the test tube.

[0044] This step prevents broken test tubes from falling directly onto the equipment platform, further reducing damage to the equipment.
