Description

Technical Field

[0001] This utility model relates to the field of laser detection technology, specifically to a size detection device. Background Technology

[0002] Laser dimension inspection utilizes the high directionality, high brightness, and high coherence of lasers to achieve non-contact precision measurement of object dimensions. It has been widely used in industrial manufacturing, architectural surveying, aerospace and other fields. In the existing technology, laser dimension inspection devices need to inspect the dimensions of individual workpieces one by one, and changing workpieces after inspection takes a certain amount of time, making it difficult to continuously inspect multiple workpieces, resulting in less than ideal inspection efficiency.

[0003] For example, patent publication number CN222164136U describes a laser dimension inspection mechanism, including a worktable with support legs fixedly installed at the four corners of its lower surface. A mounting box is slidably mounted on the worktable, and a motion component for adjusting the position of the mounting box is provided on the worktable.

A mounting frame is fixedly mounted on the connecting column, and a sliding groove is provided on the mounting frame, within which a slider is slidably mounted. An adjustment component for adjusting the position of the slider is provided on the mounting frame. This invention allows for adjustment of the laser inspection instrument's position along the Z-axis, enabling flexible adjustment of the laser inspection instrument's position according to inspection requirements when inspecting non-standard parts. It eliminates the need to disassemble the inspection equipment, making it simple to operate and convenient to use. However, this laser dimension inspection device requires sequential dimension inspection of individual workpieces, and changing workpieces after inspection takes time, making it difficult to continuously inspect multiple workpieces, resulting in less than ideal inspection efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a size detection device, which solves the problem that laser size detection devices need to sequentially detect the size of a single workpiece, and that changing the workpiece after detection requires a certain amount of time, making it difficult to continuously detect multiple workpieces and resulting in unsatisfactory detection efficiency.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a size detection device, including a base, a support frame fixedly connected to one side of the top of the base, a lifting mechanism installed on the support frame, and a continuous detection mechanism provided on the base and the lifting mechanism;

[0006] The continuous detection mechanism includes a crossbeam and a guide rail. The crossbeam is mounted on the lifting mechanism, and the guide rail is mounted on the base.

[0008] Preferably, the electric push rod is fixedly installed at the end of the crossbeam, and the output shaft end of the electric push rod is fixedly connected to the guide block. The guide block is slidably disposed inside the crossbeam, so that the electric push rod can drive the guide block to move along the guide rod.

[0009] Preferably, the two first gears mesh with each other, the two moving screws are connected by the transmission of the two first gears, and the two moving screws rotate in opposite directions, so that the two moving screws can drive the two workpieces to move in different directions.

[0010] Preferably, the two slides are symmetrically arranged on the two moving screws, and the slides are detachably connected to the vacuum suction cup by bolts, so that the vacuum suction cup can be disassembled and repaired.

[0011] Preferably, the nut seat matches the guide groove, and the slide block is slidably connected to the guide groove through the nut seat, so as to guide the movement of the slide block.

The workpiece can be changed during the detection time, reducing the time spent changing workpieces and thus effectively improving detection efficiency.

[0015] 2. This dimensional detection device uses a lifting motor to drive a lifting screw to rotate.

[0021] 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.

[0022] Please see Figures 1-3This utility model provides a technical solution: a size detection device, including a base 1, a stand 3 fixedly connected to one side of the top of the base 1, a lifting mechanism 4 installed on the stand 3, and a continuous detection mechanism 2 provided on the base 1 and the lifting mechanism 4. Multiple workpieces can be continuously detected by the continuous detection mechanism 2, reducing the time occupied by changing workpieces, thereby effectively improving detection efficiency.

[0023] The continuous detection mechanism 2 includes a crossbeam 215 and a guide rail 202. The crossbeam 215 is mounted on the lifting mechanism 4, and the guide rail 202 is mounted on the base 1. The guide rail 202 is located at the bottom of the crossbeam 215 and is fixedly connected to the base 1 to ensure stability. A guide rod 204 is fixedly connected inside the crossbeam 215, and a guide block 203 is slidably connected to the guide rod 204. A mounting plate 201 is fixedly installed at the bottom of the guide block 203, and a laser detection head 214 is fixedly installed at the bottom of the mounting plate 201. The laser detection head 214 can project a laser line. The laser detection head 214 is moved to the surface of the object, and the deformed contour is captured by a camera to achieve high-precision dimensional detection and shape reconstruction. One end of the guide block 203 is fixedly connected to an electric push rod 205, which can move the position of the laser detection head 214, thus enabling alternating detection of workpieces at two detection stations. The electric push rod 205 is fixedly installed at the end of the crossbeam, and the output shaft end of the electric push rod 205 is fixedly connected to the guide block 203. The guide block 203 is slidably disposed inside the crossbeam 215, allowing the electric push rod 205 to drive the guide block 203 along the guide rod 204. For movement, two guide grooves 206 are provided on the guide rail 202. Each guide groove 206 is rotatably connected to a moving screw 207. A first gear 208 is fixedly connected to the end of each moving screw 207. The two first gears 208 mesh with each other, and the two moving screws 207 are connected by transmission through the two first gears 208. The two moving screws 207 rotate in opposite directions, enabling them to drive two workpieces to move in different directions. A moving motor 209 is fixedly connected to the end of one moving screw 207. A support frame 210 is fixedly connected to the machine 209. Nut seats 211 are threaded onto both moving screws 207. A slide block 212 is fixedly connected to the top of the nut seat 211. The nut seat 211 matches the guide groove 206. The slide block 212 is slidably connected to the guide groove 206 via the nut seat 211, thus guiding the movement of the slide block 212. A vacuum suction cup 213 is detachably connected to the top of the slide block 212. By contacting the surface of the object, a sealed space is formed, and negative pressure (vacuum) is generated by evacuating the internal air. This is achieved using external atmospheric pressure (approximately 1 kg / cm²). 2Adsorption is achieved through internal pressure difference. Two slides 212 are symmetrically arranged on two moving screws 207, and the slides 212 are detachably connected to the vacuum suction cup 213 by bolts, so that the vacuum suction cup 213 can be disassembled and repaired.

[0024] Please see Figure 1 and Figure 4 The lifting mechanism 4 includes a lifting seat 401, which is slidably connected to the upright frame 3. The top end of the lifting seat 401 is fixedly connected to the end of the crossbeam. A lifting screw 402 is threaded onto the lifting seat 401. The lifting screw 402 is rotatably connected to the inner wall of the upright frame 3 through a bearing. A lifting motor 403 is provided on one side of the lifting screw 402. A second gear 404 is fixedly connected to both the output shaft end of the lifting motor 403 and the lifting screw 402. The two second gears 404 mesh with each other, so that the lifting motor 403 can drive the lifting screw 402 to rotate through the two second gears 404. The lifting screw 402 can be driven to rotate by the lifting motor 403, which in turn drives the lifting seat 401 to move. The movement of the lifting seat 401 drives the crossbeam to move, and the movement of the crossbeam drives the laser detection head 214 to move. This allows the height of the laser detection head 214 to be adjusted to match the workpiece size and ensure detection accuracy.

[0025] During operation, the workpiece is placed on a vacuum suction cup 213, which adheres to the workpiece. A moving motor 209 drives two moving screws 207 to rotate in opposite directions. The rotation of the screws 207 moves the nut seat 211, which in turn moves the slide 212, which in turn moves the vacuum suction cup 213. This causes the two vacuum suction cups 213 to move in opposite directions, positioning them at opposite ends of the guide rail 202, one at the inspection station and the other at the loading / unloading station. Simultaneously, an electric push rod 205 moves the guide block 203, which in turn moves the mounting plate 201, which in turn moves the laser inspection head 214. The position of the laser inspection head 214 is adjusted to allow for alternating dimensional inspection of the workpieces on the two vacuum suction cups 213. The inspection time is used to change the workpiece, reducing the time spent changing workpieces and effectively improving inspection efficiency.
