Description

Technical Field

[0001] This utility model relates to the field of sample stage technology, and in particular to a sample positioning stage for testing equipment. Background Technology

[0002] The stage of the testing equipment is a crucial component in the experimental and testing process. It not only supports and secures the object under test but also ensures the object's position and stability during testing. The sample positioning stage, as an important component of this equipment, is designed to precisely place and position the sample for various tests and analyses. This meticulous and precise design greatly improves the reliability and efficiency of the experiments.

[0003] Traditional sample positioning stages are typically fixed and cannot be adjusted to accommodate different staff heights, which limits their usability. Furthermore, staff must individually place and clamp samples onto the stage. Since the number of samples tested each time is large, and re-fixing is required each time, the process is cumbersome and lacks convenience. This not only increases workload but also wastes time, thus affecting testing efficiency. Therefore, there is an urgent need for a sample positioning stage in testing equipment to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sample positioning stage for testing equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A sample positioning stage for an inspection device includes a fixed base, a stage above the fixed base, clamping mechanisms for holding samples at the four corners of the top of the stage, an adjustment mechanism for adjusting the height of the stage at the top of the fixed base, and a feeding mechanism for automatically feeding samples at one end of the stage. The feeding mechanism includes a pusher box, a partition fixed at the center of the inner wall of the pusher box, and an electric telescopic rod installed at one end of the partition. The output shaft of the electric telescopic rod passes through the partition and is fixedly connected to a push plate. A through hole is opened at one end of the inner wall of the pusher box, and a mounting block is fixed at the bottom of the pusher box near the through hole. A roller is rotatably connected to the bottom of one end of the mounting block.

[0006] Preferably, the clamping mechanism includes clamping slots fixed at the four corners of the top of the platform. A first clamping plate is fixed at one end of the inner wall of the clamping slot, and a second clamping plate is provided at the other end of the inner wall of the clamping slot. Two sliding rods are fixed at one end of the second clamping plate, and a hole for the sliding rods to pass through is opened at the end of the inner wall of the clamping slot away from the first clamping plate. The other ends of the two sliding rods are fixed with the same connecting block.

[0007] Preferably, an L-shaped fixing plate is fixed to the other end of each of the multiple connecting blocks. A pressing block is fixed to the top of one end of the inner wall of the L-shaped fixing plate, and one side of the pressing block is cut. The pressing block can cooperate with the roller. When the cut edge moves and contacts the roller, the roller can press the pressing block and drive the second clamping plate away from the second clamping plate, which facilitates the clamping and fixing of the sample.

[0008] Preferably, one end of a return spring is fixed to the end of each of the multiple connecting blocks away from the L-shaped fixing plate, and the other end of the return spring is fixedly connected to one end of the inner wall of the clamping groove, and the return spring is located on the outer surface of the corresponding slide rod.

[0009] Preferably, the adjustment mechanism includes an electric push rod mounted on the top of the fixed base. The output shaft of the electric push rod is fixedly connected to a fixed column. The top of the fixed column has a mounting groove, and a worm gear motor is installed inside the mounting groove. The output shaft of the worm gear motor is fixedly connected to a rotating shaft, and the top of the rotating shaft is fixedly connected to the bottom of the platform. The outer wall of the fixed column has multiple heat dissipation holes.

[0010] Preferably, a connecting plate is fixed to the bottom of the outer wall of the fixed column, and support legs are fixed to the four corners of the top end of the connecting plate, and the tops of the multiple support legs are fixedly connected to the bottom of the push box.

[0011] Preferably, the two supporting legs are fixed with the same mounting plate on their sides that are close to each other, and an infrared sensor is embedded in the end of the mounting plate near the platform. Receivers are embedded in the four corners of the outer wall of the platform, with the included angle between the receivers being 90 degrees, and each of them corresponds to a clamping groove.

[0012] The beneficial effects of this utility model are as follows: 1. Due to the adoption of a feeding mechanism, the push plate is pushed by an electric telescopic rod, pushing the sample to the through hole and then guiding it into the clamping slot. When the stage rotates, the roller contacts one end of the cut edge, squeezing the L-shaped fixing plate. The connecting block and slide rod pull the second clamping plate away from the clamping slot, facilitating sample placement. When the clamping slot containing the sample moves away from the push box, the return spring resets, causing the second clamping plate to move closer to the sample and clamp it. Thus, the feeding and clamping are linked, avoiding the tedious steps of sample positioning, facilitating sample inspection by staff, improving inspection efficiency, and offering simple operation and high practicality.

[0013] 2. Due to the adoption of an adjustment mechanism, when the height of the stage needs to be adjusted, the electric push rod can be operated to move the stage upward, making it convenient for staff to adjust the stage to a suitable height for themselves and facilitating the inspection of samples.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-5 A sample positioning platform for an inspection device includes a fixed base 1, a platform 4 above the fixed base 1, clamping mechanisms for clamping samples at the four corners of the top of the platform 4, an adjustment mechanism for adjusting the height of the platform 4 at the top of the fixed base 1, and a feeding mechanism for automatically feeding samples at one end of the platform 4. The feeding mechanism includes a pusher box 3, a partition is fixed at the center of the inner wall of the pusher box 3, and an electric telescopic rod 303 is installed at one end of the partition. The output shaft of the electric telescopic rod 303 passes through the partition and is fixedly connected to a pusher plate 304. A through hole 305 is opened at one end of the inner wall of the pusher box 3. A mounting block 5 is fixed at the bottom of the pusher box 3 near the through hole 305. A roller 501 is rotatably connected to the bottom of one end of the mounting block 5.

[0018] In this utility model, the clamping mechanism includes clamping slots 401 fixed at the four corners of the top of the platform 4. The included angle between each clamping slot 401 is 90 degrees. A first clamping plate 402 is fixed at one end of the inner wall of the clamping slot 401, and a second clamping plate 403 is provided at the other end of the inner wall of the clamping slot 401. Two sliding rods 404 are fixed at one end of the second clamping plate 403, and a hole for the sliding rods 404 to pass through is opened at the end of the inner wall of the clamping slot 401 away from the first clamping plate 402. The same connecting block 405 is fixed at the other end of the two sliding rods 404.

[0019] In this utility model, an L-shaped fixing plate 502 is fixed to the other end of each of the multiple connecting blocks 405. An extrusion block 503 is fixed to the top of one end of the inner wall of the L-shaped fixing plate 502. One side of the extrusion block 503 is cut edge 504. The extrusion block 503 can cooperate with the roller 501. When the cut edge 504 moves and contacts the roller 501, the roller 501 can extrude the extrusion block 503 and drive the second clamping plate 403 away from the second clamping plate 403, which facilitates the clamping and fixing of the sample.

[0020] In this utility model, one end of a return spring 406 is fixed to one end of each of the multiple connecting blocks 405 away from the L-shaped fixing plate 502, and the other end of the return spring 406 is fixedly connected to one end of the inner wall of the clamping groove 401, and the return spring 406 is located on the outer surface of the corresponding slide rod 404.

[0021] In this utility model, the adjustment mechanism includes an electric push rod 2 installed on the top of the fixed base 1. The output shaft of the electric push rod 2 is fixedly connected to a fixed column 201. The top of the fixed column 201 is provided with a mounting groove, and a worm gear motor 203 is installed inside the mounting groove. The output shaft of the worm gear motor 203 is fixedly connected to a rotating shaft 204, and the top of the rotating shaft 204 is fixedly connected to the bottom of the platform 4. The outer wall of the fixed column 201 is provided with multiple heat dissipation holes 202.

[0022] In this utility model, a connecting plate 302 is fixed to the bottom of the outer wall of the fixed column 201, and a support leg 301 is fixed to each of the four corners of the top end of the connecting plate 302, and the top of the multiple support legs 301 is fixedly connected to the bottom of the push box 3.

[0023] In this utility model, the two support legs 301 are fixed with the same mounting plate 306 on their sides that are close to each other, and an infrared sensor 307 is embedded in the end of the mounting plate 306 near the platform 4. Receivers 400 are embedded in the four corners of the outer wall of the platform 4, and the included angle between the receivers 400 is 90 degrees, and they correspond one-to-one with the clamping grooves 401.

[0024] Working Principle: When convenient positioning and inspection of samples are required, the sample is first placed on one end of the inner wall of the pusher box 3. Then, the worm gear motor 203 is controlled by the controller to rotate, which drives the rotating shaft 204 to rotate, and in turn, the stage 4 rotates. The stage 4 then drives the receiver 400 to rotate. When the receiver 400 receives a signal from the infrared sensor 307, the controller shuts off the worm gear motor 203 and activates the electric telescopic rod 303. The electric telescopic rod 303 pushes the push plate 304, which in turn pushes the sample on one end of the inner wall of the pusher box 3, pushing it to the through hole 305. The sample then falls through the through hole 305 into the clamping slot 401, thus achieving automatic sample feeding. When the stage 4 rotates, it simultaneously drives the clamping slot 401 to rotate, and also drives the corresponding L-shaped fixing plate 502 to rotate. When the cutting edge 504 first contacts the roller 501, the roller 501 will squeeze the L-shaped fixing plate 502. Then, the L-shaped fixing plate 502 will pull the connecting block 405 away from the first clamping plate 402. The connecting block 405 will pull the second clamping plate 403 away from the first clamping plate 402 through the slide rod 404, increasing the distance between the first clamping plate 402 and the second clamping plate 403. After the sample is loaded, the controller will control the worm gear motor 203 to run again, and then drive the stage 4 to rotate 90 degrees. Then, the squeezing block 503 will move away from the roller 501. At this time, the return spring 406 will drive the connecting block 405 to reset, and drive the second clamping plate 403 to reset and approach the outer surface of the sample, clamping and fixing it. Thus, through the linkage between feeding and clamping, it is convenient to position and fix the sample. The staff only needs to place the sample on one end of the inner wall of the push box 3, eliminating the need for complicated operations and improving the efficiency of inspection.

[0025] However, as is well known to those skilled in the art, the working principles and wiring methods of some electrical components such as the electric push rod 2, receiver 400, infrared sensor 307, worm gear motor 203, and electric telescopic rod 303 are commonplace and belong to conventional methods or common knowledge. Therefore, they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience. The control method of this invention is through a controller or manual control. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this invention is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail here.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
