Description

Technical Field

[0001] This invention relates to the field of sample wheel device technology, specifically to an unattended sample wheel device with automated sample changing capability. Background Technology

[0002] The sample wheel device is an automated device primarily used in various experimental, testing, or analytical scenarios to automatically perform sample switching and positioning operations according to pre-set procedures and rules, eliminating the need for continuous on-site human intervention and management. Its core feature lies in its ability to autonomously and orderly rotate the samples to be tested, accurately delivering different samples sequentially to the corresponding testing and analysis positions (such as sending samples to the X-ray irradiation area, spectral detection area, etc.). This allows the entire sample testing process to proceed smoothly and efficiently. Even without constant human supervision, it can reliably and continuously operate, enabling continuous and automated testing of multiple samples. This significantly improves work efficiency and reduces errors and labor costs associated with manual operation.

[0003] In use, the workpiece to be inspected is usually placed in the corresponding position and then automatically inspected without human intervention. However, in actual use, after the workpiece is inspected, it usually needs to be removed by personnel and replaced with a new workpiece. If this process is not smooth, it will indeed disrupt the overall inspection rhythm, cause inconvenience, and affect the inspection efficiency. Therefore, it is necessary to design a practical, automated, unattended sample wheel device for sample changing. Summary of the Invention

[0004] The purpose of this invention is to provide an unattended sample wheel device with automated sample changing capability to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an unattended sample wheel device with automatic sample changing capability, comprising a test box, a placement platform fixedly connected to the lower side of the inner wall of the test box, a detection mechanism cooperating with the placement platform fixedly connected to the upper side of the inner wall of the test box, a rotating rod rotatably cooperating with the lower side of the test box, and a driving mechanism cooperating with the rotating rod provided on the lower side of the inner wall of the test box. A horizontal plate is fixedly connected to the upper side of the rotating rod, and two electric push cylinders are fixedly connected to the horizontal plate. The output ends of the two electric push cylinders are fixedly connected to a tightening mechanism. Two material platforms are correspondingly arranged on the lower side of the inner wall of the test chamber.

[0006] According to the above technical solution, the driving mechanism includes a drive motor fixedly connected to the lower side of the test box, a drive gear fixedly connected to the output end of the drive motor, and a driven sprocket fixedly connected to the rotating rod and meshing with the drive gear.

[0007] According to the above technical solution, the tightening mechanism includes an empty slot block fixedly connected to the output ends of the two electric push cylinders, a bidirectional lead screw rotatably fitted on the inner wall of the empty slot block, a tightening block threaded onto the bidirectional lead screw, and a drive motor fixedly connected to one side of the empty slot block and fixedly connected to the bidirectional lead screw.

[0008] According to the above technical solution, a plurality of support legs are fixedly connected to the lower side of the test box, and the plurality of support legs are welded to the test box. Shock-absorbing pads are fixedly connected to the lower side of the plurality of support legs.

[0009] According to the above technical solution, an observation port is provided on one side of the test box, and an insulating transparent glass is fixedly connected to the inner wall of the observation port.

[0010] According to the above technical solution, a soft pad is fixedly connected to one side of each tightening block.

[0011] According to the above technical solution, a guide seat is fixedly connected to one side of the horizontal plate, and a guide rod that slides with the guide seat is fixedly connected to the upper side of the hollow slot block.

[0012] According to the above technical solution, the drive mechanism, rotating rod, horizontal plate, and material stage form a "rotation drive - sample transfer" linkage function: the output end of the drive motor drives the active gear to rotate, the active gear meshes with the driven sprocket, and drives the rotating rod to rotate around its own axis; the rotating rod drives the horizontal plate fixed on the upper side to rotate synchronously, and the electric push cylinder and tightening mechanism on the horizontal plate rotate with the horizontal plate; when the horizontal plate rotates to the top of the material stage, the tightening mechanism can grab the sample on the material stage, and when it continues to rotate to the top of the placement stage, the tightening mechanism releases the sample, realizing the automatic transfer of the sample between the material stage and the placement stage.

[0013] According to the above technical solution, the guide seat, guide rod, electric push cylinder, and empty slot block form a "moving guidance-precise positioning" linkage function: when the output end of the electric push cylinder pushes the empty slot block to move horizontally, the guide rod on the upper side of the empty slot block is simultaneously embedded in the guide seat and slides along the axis of the guide seat; the sliding cooperation between the guide rod and the guide seat restricts the movement trajectory of the empty slot block and avoids the empty slot block from deviating; this linkage ensures that the tightening mechanism moves precisely to the sample gripping or releasing position under the drive of the electric push cylinder, with an error ≤2mm.

[0014] According to the above technical solution, the tightening mechanism, soft pad, detection mechanism, and material stage form a "sample tightening-protection detection" linkage function: when the drive motor drives the bidirectional lead screw to rotate, the bidirectional lead screw drives the two tightening blocks to move closer to each other, and the soft pad on one side of the tightening block contacts the sample surface and clamps the sample; the soft pad undergoes elastic deformation to avoid excessive clamping force from damaging the sample; after clamping, the sample is rotated to the top of the placement stage by the horizontal plate, the tightening mechanism releases the sample, and the detection mechanism detects the sample on the placement stage; after the detection is completed, the tightening mechanism clamps the sample again, rotates to the top of another material stage and releases it, realizing an automated closed loop of "grabbing-detection-storage".

[0015] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: By incorporating components such as a drive mechanism and a tightening mechanism, this invention enables the drive motor, drive gear, and driven sprocket in the drive mechanism to work together, allowing the rotating rod to rotate as needed. This allows the horizontal plate and its connected components to perform a rotation function similar to a sample wheel, automatically moving samples from different positions to their corresponding detection positions. This eliminates the need for manual handling and sample switching, greatly improving the automation level of the detection process, saving manpower, and accelerating the detection process. Furthermore, the tightening mechanism can stably tighten or loosen the sample, thereby improving the sample fixation effect during the detection process and increasing the automation level of sample rotation to the corresponding detection position. This reduces the workload of manual operation and improves the overall detection efficiency. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-5 The present invention provides a technical solution: an unattended sample wheel device with automatic sample changing, including a test box 1, a placement platform 2 fixedly connected to the lower side of the inner wall of the test box 1, a detection mechanism 3 that cooperates with the placement platform 2 fixedly connected to the upper side of the inner wall of the test box 1, a rotating rod 4 rotatably connected to the lower side of the test box 1, and a driving mechanism 5 that cooperates with the rotating rod 4 provided on the lower side of the inner wall of the test box 1. A horizontal plate 6 is fixedly connected to the upper side of the rotating rod 4. Two electric push cylinders 7 are fixedly connected to the horizontal plate 6. A tightening mechanism 8 is fixedly connected to the output end of each of the two electric push cylinders 7. Two material platforms 9 are correspondingly set on the lower side of the inner wall of the test chamber 1.

[0019] Please see Figure 2 and Figure 3 as well as Figure 5 The drive mechanism 5 includes a drive motor 501 fixedly connected to the lower side of the test box 1, a drive gear 502 fixedly connected to the output end of the drive motor 501, and a driven sprocket 503 fixedly connected to the rotating rod 4 and meshing with the drive gear 502. After the drive motor 501 is started, the drive gear 502 at its output end rotates, which drives the driven sprocket 503 on the rotating rod 4 that meshes with it to rotate, thereby causing the rotating rod 4 to rotate as well, thus realizing the drive of the components connected to the rotating rod 4.

[0020] Please see Figure 4The tightening mechanism 8 includes an empty slot block 801 fixedly connected to the output ends of two electric push cylinders 7, a bidirectional lead screw 802 rotatably fitted on the inner wall of the empty slot block 801, a tightening block 803 threadedly fitted on the bidirectional lead screw 802, and a drive motor 804 fixedly connected to one side of the empty slot block 801 and fixedly connected to the bidirectional lead screw 802. After the drive motor 804 is started, it drives the bidirectional lead screw 802 inside the empty slot block 801 to rotate, causing the tightening block 803 threadedly fitted on the bidirectional lead screw 802 to move relative to it, thereby realizing the tightening or loosening operation of the sample. The entire mechanism is moved in position by being driven by the output ends of the electric push cylinders 7.

[0021] Please see Figure 1 Multiple support legs 10 are fixedly connected to the lower side of the test box 1. The multiple support legs 10 are welded to the test box 1. Shock-absorbing pads are fixedly connected to the lower side of each of the multiple support legs 10. The support legs 10 are fixed to the lower side of the test box 1 by welding. The shock-absorbing pads connected to the lower side can play a buffering and shock-absorbing role, thereby enhancing the stability of the entire device when placed and reducing the impact of external vibration on the operation of the device.

[0022] Please see Figure 1 The test chamber 1 has an observation port 11 on one side, and an isolation transparent glass 12 is fixedly connected to the inner wall of the observation port 11. The observation port 11 on one side of the test chamber 1 and the isolation transparent glass 12 are fixedly installed on the inner wall, so that the operator can observe the situation inside the chamber through the glass without opening the test chamber 1, so as to understand the operating status of the device and the sample testing status in a timely manner.

[0023] Please see Figure 2 and Figure 4 A soft pad 13 is fixedly connected to one side of the tightening block 803. When the tightening block 803 tightens and fixes the sample, the soft pad 13 can contact the sample and play a buffering and protective role to avoid damage to the sample surface during the tightening process.

[0024] Please see Figure 5 A guide seat 14 is fixedly connected to one side of the horizontal plate 6, and a guide rod 15 that slides with the guide seat 14 is fixedly connected to the upper side of the empty slot block 801. During the operation of the device, when the empty slot block 801 moves, the guide rod 15 fixedly connected above it will slide along the guide seat 14 fixedly connected to one side of the horizontal plate 6. Through this sliding engagement, the movement of the empty slot block 801 is guided, ensuring that the empty slot block 801 moves more smoothly and accurately, and ensuring that the tightening mechanism 8 and other related components connected to it can accurately complete the corresponding operations.

[0025] In this invention, the drive mechanism 5, the rotating rod 4, the horizontal plate 6, and the material platform 9 form a "rotation drive - sample transfer" linkage function: the output end of the drive motor 501 drives the active gear 502 to rotate, the active gear 502 meshes with the driven sprocket 503 to drive the rotating rod 4 to rotate around its own axis; the rotating rod 4 drives the horizontal plate 6 fixed on the upper side to rotate synchronously, and the electric push cylinder 7 and the tightening mechanism 8 on the horizontal plate 6 rotate with the horizontal plate 6; when the horizontal plate 6 rotates to above the material platform 9, the tightening mechanism 8 can grab the sample on the material platform 9, and when it continues to rotate to above the placement platform 2, the tightening mechanism 8 releases the sample, realizing the automatic transfer of the sample between the material platform 9 and the placement platform 2.

[0026] In this invention, the guide seat 14, guide rod 15, electric push cylinder 7, and empty slot block 801 form a "moving guidance-precise positioning" linkage function: when the output end of the electric push cylinder 7 pushes the empty slot block 801 to move horizontally, the guide rod 15 on the upper side of the empty slot block 801 is simultaneously embedded in the guide seat 14 and slides along the axis of the guide seat 14; the sliding cooperation between the guide rod 15 and the guide seat 14 restricts the movement trajectory of the empty slot block 801 and avoids the empty slot block 801 from deviating; this linkage ensures that the tightening mechanism 8 moves precisely to the sample gripping or releasing position under the drive of the electric push cylinder 7, with an error ≤2mm.

[0027] In this invention, the tightening mechanism 8, the soft pad 13, the detection mechanism 3, and the material stage 9 form a "sample tightening-protection detection" linkage function: when the drive motor 804 drives the bidirectional lead screw 802 to rotate, the bidirectional lead screw 802 drives the two tightening blocks 803 to move closer to each other, and the soft pad 13 on one side of the tightening block 803 contacts the sample surface and clamps the sample; the soft pad 13 generates elastic deformation to avoid excessive clamping force from damaging the sample; after clamping, the sample rotates with the horizontal plate 6 to the top of the placement platform 2, the tightening mechanism 8 releases the sample, and the detection mechanism 3 detects the sample on the placement platform 2; after the detection is completed, the tightening mechanism 8 clamps the sample again, rotates to the top of another material stage 9 and releases it, realizing an automated closed loop of "grabbing-detection-storage".

[0028] The implementation principle of this application is as follows: When in use, the device is first connected to the power supply, and the drive motor 501 in the drive mechanism 5 is started. The drive gear 502 at the output end of the drive motor 501 starts to rotate, and the driven sprocket 503 (fixedly connected to the rotating rod 4) meshes with it and rotates accordingly, thereby driving the rotating rod 4 to rotate. The horizontal plate 6 fixedly connected to the upper side of the rotating rod 4 also rotates synchronously, so that the components on the horizontal plate 6 can change position, realizing a wheel-like rotation function, moving materials or samples in different positions to the corresponding detection positions. When it is necessary to operate on the sample on the material stage 9, after the horizontal plate 6 is rotated to the corresponding position, the electric push cylinder 7 is activated to push the tightening mechanism 8 to move towards the material stage 9. After reaching the appropriate position, the drive motor 804 in the tightening mechanism 8 is activated. The drive motor 804 drives the bidirectional lead screw 802 to rotate. Since the tightening block 803 and the bidirectional lead screw 802 are threadedly connected, the rotation of the bidirectional lead screw 802 will cause the two tightening blocks 803 to move relative to each other. With the assistance of the soft pad 13, the sample is tightened and fixed. There are two material stages 9, one for placing the part to be tested and the other for placing the part after testing, which is convenient for subsequent testing and other operations. During the movement of the tightening block 803, the guide rod 15 fixedly connected above it will slide along the guide seat 14 to play a guiding role and ensure the smooth movement of the tightening block 803. After the sample is secured through the above operations, the horizontal plate 6 moves the sample to the corresponding position below the detection mechanism 3 (the detection mechanism 3 is fixedly connected to the upper side of the inner wall of the test chamber 1 and works with the placement platform 2 to complete the detection work). The detection mechanism 3 can then perform the detection on the sample. Throughout the process, the coordinated operation of the drive mechanism 5, the electric push cylinder 7, the tightening mechanism 8, etc., achieves automated sample rotation, fixation, and detection operations without the need for continuous manual intervention. It can automatically complete the rotation, positioning, and tightening of the sample according to the set process, greatly reducing the workload of manual operation and achieving a relatively efficient automated detection process.
