Description

Technical Field

[0001] This utility model relates to the technical field of grating scanner fixing equipment, specifically a highly adaptable clamp for grating scanners. Background Technology

[0002] A grating scanner is a device that uses the principle of gratings to convert optical signals into electrical signals through scanning motion. It is commonly used in image scanning, industrial inspection, and other fields. It can collect and analyze information such as details and dimensions of an object's surface. In semiconductor manufacturing, precision machining, and other scenarios, it can accurately detect defects in workpieces or complete dimensional measurements. When using a grating scanner, it is essential to ensure that the object's position remains stable during the scanning process to avoid inaccurate scanning results or ghosting caused by movement. Therefore, a fixing fixture is required.

[0003] Existing grating scanner fixtures are fixed to the center of the scanner worktable by bolts or slots. The fixture components are adjusted according to the scanning requirements. The object is placed on the working surface of the fixture. The knob is manually turned or the clamp is used to pre-tighten the fixture fastener. The force should be such that the object does not wobble. It is not fully locked yet so that it can be fine-tuned later.

[0004] Existing fixtures for grating scanners require manual tightening and loosening of individual fasteners to clamp and fix the object to be scanned. It is difficult to control the torque of each fastener to be consistent. During the process of manually tightening each fastener, the workpiece may be displaced due to different force sequences, resulting in symmetry errors in the scanned 3D model. To address this, we propose a fixture for grating scanners with strong adaptability. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a highly adaptable grating scanner fixture that can adapt to workpieces of various shapes. The fixing plate clamps the workpiece synchronously from different directions, which improves the accuracy of clamping and positioning, provides a guarantee for high-precision scanning, and can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a highly adaptable clamp for a grating scanner, comprising a base, wherein the base has a support platform inside and a clamping mechanism;

[0007] Clamping mechanism: It includes guide grooves, sliders, dovetail grooves, dovetail sliders and fixing plates. The upper surface of the support platform is provided with evenly distributed guide grooves. Sliders are slidably connected inside the guide grooves. Dovetail grooves are provided on the inner walls of the long sides of the guide grooves. Dovetail sliders are fixedly connected to the outside of the sliders. The dovetail sliders are slidably connected to the inside of the adjacent dovetail grooves. The top of each slider is connected to a fixing plate by bolts. It can adapt to workpieces of various shapes. The fixing plate clamps the workpieces simultaneously from different directions, which improves the accuracy of clamping and positioning and provides a guarantee for high-precision scanning.

[0008] Furthermore, a microcontroller is provided on the outside of the base, and the input terminal of the microcontroller is electrically connected to an external power source to provide electrical connections for various electrical appliances.

[0009] Furthermore, the clamping mechanism also includes a rotating column, a rectangular plate, and an L-shaped rod. The rotating column is rotatably connected between the upper and lower inner walls of the support platform. A rectangular plate is fixedly sleeved on the outside of the rotating column. L-shaped rods are rotatably connected to the four corner edges of the lower surface of the rectangular plate. The ends of the L-shaped rods away from the rotating column are rotatably connected to the lower surfaces of the vertically adjacent sliders to achieve synchronous movement.

[0010] Furthermore, the clamping mechanism also includes a drive assembly, which includes a worm gear and a worm. The worm gear is fixedly sleeved on the outside of the rotating column, and the worm is rotatably connected to the inner wall of the right side of the support platform. The worm gear and the worm are meshed together to ensure stable transmission.

[0011] Furthermore, the drive assembly also includes a motor, which is mounted on the bottom wall of the support platform. The right end of the motor's output shaft is fixedly connected to the left end of the worm gear, and the input end of the motor is electrically connected to the output end of the microcontroller to provide clamping drive.

[0012] Furthermore, the left and right inner walls of the base are respectively provided with sliding grooves, and the front ends of the left and right sides of the support platform are provided with sliding columns. The sliding columns are slidably connected to the interior of the adjacent sliding grooves on the same side. The bottom wall of the base is provided with an electric push rod. The telescopic end of the electric push rod is rotatably connected to a U-shaped seat. The top end of the U-shaped seat is fixedly connected to the rear end of the lower surface of the support platform. The input end of the electric push rod is electrically connected to the output end of the microcontroller to achieve angle tilting.

[0013] Furthermore, rubber anti-slip pads are fixedly connected to the four corners of the bottom of the base to prevent the clamp from sliding during use.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This highly adaptable fixture for raster scanners has the following advantages:

[0015] The motor drives the worm gear to rotate, which in turn drives the worm wheel to rotate around the axis of the rotating column. The rectangular plate fixedly sleeved on its outside rotates accordingly. The L-shaped rod swings around the connection point between the L-shaped rod and the rectangular plate. The swing of the L-shaped rod pushes the slider to slide in the guide groove. The four fixed plates can move synchronously towards the center from different directions to achieve centering and clamping of the workpiece. This avoids the randomness and human error of manual operation, ensures the consistency of clamping force and position each time, and allows for flexible adjustment of the clamping range of the fixed plates. It is compatible with workpieces of different sizes, expands the applicability of the fixture, ensures that the clamping components move accurately along the preset direction, and improves the accuracy of the grating scanner in clamping and positioning objects.

[0020] 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.

[0021] Please see Figure 1-3This embodiment provides a technical solution: a highly adaptable fixture for a raster scanner, including a base 1, an internal support platform 2, and a clamping mechanism 6. A microcontroller 5 is located on the outside of the base 1, with its input terminal electrically connected to an external power source. Slide grooves 3 are respectively formed on the left and right inner walls of the base 1. Slide posts 4 are provided at the front ends of both sides of the support platform 2, and each slide post 4 is slidably connected to the interior of an adjacent slide groove 3 on the same side. An electric push rod 7 is provided on the bottom wall of the base 1, and a U-shaped seat 8 is rotatably connected to the telescopic end of the electric push rod 7. The top of the U-shaped base 8 is fixedly connected to the rear end of the lower surface of the support platform 2. The input end of the electric push rod 7 is electrically connected to the output end of the microcontroller 5. Rubber anti-slip pads 9 are fixedly connected to the four corners of the bottom end of the base 1. When scanning an object with a grating scanner, the object must first be placed in the middle of the support platform 2. During the scanning process, when the object needs to be tilted, the microcontroller 5 controls the electric push rod 7 to start running, thereby pushing the rear end of the support platform 2 to rise, so that the front sliding column 4 slides inside the sliding groove 3, so that the object reaches the required scanning angle.

[0022] Clamping mechanism 6 includes guide grooves 61, sliders 62, dovetail grooves 63, dovetail sliders 64, and fixing plates 65. The upper surface of the support platform 2 has evenly distributed guide grooves 61. Sliders 62 are slidably connected inside the guide grooves 61. Dovetail grooves 63 are formed on the inner walls of the long sides of the guide grooves 61. Dovetail sliders 64 are fixedly connected to the outside of the sliders 62. The dovetail sliders 64 are slidably connected to the interior of adjacent dovetail grooves 63. The top of each slider 62 is bolted to a fixing plate 65. The clamping mechanism 6 also includes a rotating column 66, a rectangular plate 67, and an L-shaped rod 68. The rotating column 66 is rotatably connected between the upper and lower inner walls of the support platform 2. A rectangular plate 67 is fixedly sleeved on the outside of the rotating column 66. L-shaped rods 68 are rotatably connected to the four corners of the lower surface of the rectangular plate 67. The ends of the L-shaped rods 68 away from the rotating column 66 are rotatably connected to the lower surfaces of the vertically adjacent sliders 62. The clamping mechanism 6 also includes a drive assembly 69, which includes a worm gear 691 and a worm 692. The worm gear 691 is fixedly sleeved on the outside of the rotating column 66, and the worm 692 is rotatably connected to the inner right wall of the support platform 2. The worm gear 691 and the worm 692 are meshed together. The drive assembly 69 also includes a motor 693, which is located on the bottom wall of the support platform 2. The right end of the output shaft of the motor 693 is connected to the worm 692. The left end of 92 is fixedly connected, and the input end of motor 693 is electrically connected to the output end of microcontroller 5. Microcontroller 5 controls motor 693 to work. The output shaft is fixedly connected to the left end of worm 692, driving worm 692 to rotate. Since worm wheel 691 meshes with worm 692, the rotation of worm 692 will drive worm wheel 691 to rotate around the axis of rotating column 66. Therefore, when worm wheel 691 rotates, it will drive rotating column 66 to rotate between the upper and lower inner walls of support platform 2. When rotating column 66 rotates, rectangular plate 67 fixedly sleeved on its outside will rotate accordingly. L-shaped rods 68 at the four corners of the lower surface of rectangular plate 67 are rotatably connected to rectangular plate 67. When rectangular plate 67 rotates, the L-shaped rods 68 will rotate. The rod 68 swings around its connection point with the rectangular plate 67. The swing of the L-shaped rod 68 pushes the slider 62 to slide in the guide groove 61. When the slider 62 slides in the guide groove 61, the dovetail slider 64 outside it slides synchronously in the dovetail groove 63. The dovetail structure can prevent the slider 62 from deviating during the sliding process and ensure the stability of the sliding. The fixing plate 65 at the top of the slider 62 is connected by bolts and moves with the slider 62. Multiple fixing plates 65 can clamp the workpiece from different directions. By controlling the forward and reverse rotation of the motor 693, the opening and clamping actions of the fixing plates 65 can be realized, and the object is stably fixed to the upper surface of the support table 2 for grating scanning.

[0023] The working principle of the highly adaptable grating scanner fixture provided by this utility model is as follows: When scanning an object with a grating scanner, the object must first be placed in the middle of the support platform 2. The microcontroller 5 controls the motor 693 to work, and the output shaft is fixedly connected to the left end of the worm gear 692, driving the worm gear 692 to rotate. Since the worm wheel 691 meshes with the worm gear 692, the rotation of the worm gear 692 will drive the worm wheel 691 to rotate around the axis of the rotating column 66. Therefore, when the worm wheel 691 rotates, it will drive the rotating column 66 to rotate between the upper and lower inner walls of the support platform 2. When the rotating column 66 rotates, the rectangular plate 67 fixedly sleeved on its outside will rotate accordingly. The L-shaped rods 68 at the four corners of the lower surface of the rectangular plate 67 are rotatably connected to the rectangular plate 67. When the rectangular plate 67 rotates, the L-shaped rods 68 will swing around the connection point between them and the rectangular plate 67. The swing of 8 will push the slider 62 to slide in the guide groove 61. When the slider 62 slides in the guide groove 61, its external dovetail slider 64 will slide synchronously in the dovetail groove 63. The dovetail structure can prevent the slider 62 from deviating during the sliding process and ensure the stability of the sliding. The fixed plate 65 connected to the top of the slider 62 by bolts moves with the slider 62. Multiple fixed plates 65 can clamp the workpiece from different directions. By controlling the forward and reverse rotation of the motor 693, the opening and clamping action of the fixed plate 65 can be realized, and the object is stably fixed to the upper surface of the support table 2 for grating scanning. During the scanning process, when it is necessary to tilt the object, the microcontroller 5 controls the electric push rod 7 to start running, which in turn pushes the rear end of the support table 2 to rise, so that the front sliding column 4 slides in the groove 3, so that the object reaches the required scanning angle.

[0024] It is worth noting that the microcontroller 5 disclosed in the above embodiments can be a PIC12F675, the motor 693 can be a YS8024, and the electric actuator 7 can be a DYTP. The microcontroller 5 controls the operation of the motor 693 and the electric actuator 7 using methods commonly used in the prior art.

[0025] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
