Description

Technical Field

[0001] This utility model relates to the field of visual quality inspection machine technology, specifically an automatic positioning device for visual quality inspection machines based on pneumatic clamping. Background Technology

[0002] In modern industrial automated production, vision inspection machines are core equipment for ensuring product quality, and their positioning and sorting efficiency directly affects the overall efficiency of the production line. Traditional positioning mechanisms mostly use rigid mechanical clamping or single pneumatic clamping methods, lacking the ability to adapt to changes in workpiece shape and size, leading to positioning deviations. Fixed-layout pneumatic grippers are difficult to adjust the spacing and angle flexibly, requiring frequent manual clamp changes, which severely restricts the inspection efficiency of various workpieces. The cameras of traditional equipment are usually fixed and can only cover a single inspection angle. For workpieces with complex structures, such as multi-faceted or deep cavities, manual flipping of the workpiece or the addition of multiple inspection modules are required, resulting in high equipment costs and large footprints. In addition, the sorting process mostly relies on manual labor or simple conveyor belt diversion, making it impossible to classify qualified and unqualified workpieces in real time and accurately based on visual inspection results, which can easily lead to mixed materials or missed inspections.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0029] Example 1: As Figures 1-3 ,include:

[0030] The main feeder includes a first frame 100, and the inner wall of the first frame 100 is rotatably connected to the first feed roller 110 via bearings;

[0031] The automatic positioning assembly includes a turntable 310, the inner wall of which is rotatably connected to a second feed roller 330 via bearings;

[0032] The sorting and feeding machine has two sets arranged symmetrically on the left and right. The sorting and feeding machine includes a second frame 400, and the inner wall of the second frame 400 is rotatably connected to the third feeding roller 410 through bearings.

[0033] The specific application scenario of this embodiment is as follows: The first frame 100 of the main feeder provides overall support, the first feeding roller 110 rotates under the action of the bearing to realize the conveying of the workpiece, the turntable 310 of the automatic positioning component can rotate, the second feeding roller 330 rotates inside it to receive the workpiece sent by the main feeder, and adjusts the direction of the workpiece by rotating the turntable 310, the two sets of second frames 400 of the sorting feeder are symmetrically arranged, the third feeding roller 410 rotates, and according to the detection result of the workpiece, qualified and unqualified workpieces are conveyed to different directions to complete the sorting work. The entire device realizes the transmission, positioning and sorting of workpieces through the coordinated rotation of each feeding roller.

[0034] Example 2: Figure 1 and Figure 2 Pneumatic clamping assemblies are fixedly installed on the top outer walls of both sides of the first frame 100. The pneumatic clamping assemblies are symmetrically arranged in two sets. The pneumatic clamping assemblies include cylinder frames 200, which are fixedly installed on the top outer wall of the first frame 100. A push plate 220 is fixedly installed on the output end of the cylinder 210.

[0035] The specific application scenario of this embodiment is as follows: The cylinder frames 200 on both sides of the top of the first frame 100 provide the mounting base for the cylinder 210. When it is necessary to clamp and position the workpiece, the cylinder 210 is started, and its output end pushes the push plate 220 to make linear motion. The two sets of pneumatic clamping components on the left and right work together to clamp the workpiece from both sides, so that the workpiece is kept in a stable position on the main feeder, avoiding deviation during the conveying process, and providing good conditions for subsequent visual inspection and processing.

[0036] Example 3: Figure 1 and Figure 2 A first servo motor 120 is fixedly installed on the inner wall of the first frame 100. Several first feeding rollers 110 are provided. Adjacent first feeding rollers 110 are connected by a first sprocket and a second chain. The outer wall of the output shaft of the first servo motor 120 is connected to the outer wall of the starting first feeding roller 110 by a first sprocket and a second chain.

[0037] The specific application scenario of this embodiment is as follows: After the first servo motor 120 is started as a power source, its output shaft transmits power to the first feeding roller 110 at the starting end through the first sprocket and the second chain, causing the first feeding roller 110 at the starting end to rotate. Since the adjacent first feeding rollers 110 are also connected by the first sprocket and the second chain, the rotation of the first feeding roller 110 at the starting end will drive the subsequent first feeding rollers 110 to rotate synchronously in sequence, thereby realizing the continuous conveying of the workpiece on the main feeder and ensuring the stability and synchronicity of the conveying process.

[0038] Example 4: Figure 1 and Figure 4 A visual inspection system is fixedly installed on the top outer wall of the first frame 100. The visual inspection system includes a support frame 130, which is fixedly installed on the top two outer walls of the first frame 100. The bottom inner wall of the first frame 100 is rotatably connected to a U-shaped frame 140 via a pivot. The inner wall of the U-shaped frame 140 is rotatably connected to a visual inspection and recognition camera 150. A first stepper motor for driving the pivot is fixedly installed on the inner wall of the support frame 130. A second stepper motor 160 is fixedly installed on the outer wall of the U-shaped frame 140. The second stepper motor 160 is used to drive the visual inspection and recognition camera 150 to rotate.

[0039] The specific application scenario of this embodiment is as follows: The first stepper motor on the support frame 130 drives the rotating shaft to rotate, thereby driving the U-shaped frame 140 to rotate, realizing the horizontal angle adjustment of the visual inspection and recognition camera 150. At the same time, the second stepper motor 160 on the outer wall of the U-shaped frame 140 drives the visual inspection and recognition camera 150 to rotate inside the U-shaped frame 140, realizing the vertical angle adjustment. Through the angle adjustment in these two directions, the visual inspection and recognition camera 150 can flexibly capture and inspect the workpiece from all directions. The captured image information is transmitted to the control system to determine whether the workpiece is qualified, providing a basis for subsequent sorting work.

[0040] Example 5: Figure 1 and Figure 5 The automatic positioning component includes a base plate 300, which is fixedly installed on the inner wall of the first frame 100. The top of the base plate 300 is rotatably connected to a turntable 310 via a second rotating shaft. A third stepper motor for driving the second rotating shaft is fixedly installed on the inner wall of the base plate 300. The turntable 310 has inlet and outlet 320 at both ends. The inner wall of the turntable 310 is rotatably connected to a third feeding roller 330 via bearings. There are several third feeding rollers 330. A drive shaft 331 is provided in the middle of the third feeding roller 330. A second sprocket 332 is fixedly installed on the outer wall of the drive shaft 331. Adjacent second sprockets 332 are sequentially connected by a second chain 333. A second servo motor 340 is fixedly installed on the inner wall of the top of the turntable 310. The outer wall of the output shaft of the second servo motor 340 is connected to the outer wall of the starting drive shaft 331 via a second sprocket 332 and a second chain 333.

[0041] The specific application scenario of this embodiment is as follows: The third stepper motor on the inner wall of the base plate 300 drives the second rotating shaft to rotate, thereby driving the turntable 310 to rotate, which can adjust the workpiece to the required angle position. After the second servo motor 340 is started, it transmits power to the starting end drive shaft 331 through the second sprocket 332 and the second chain 333, causing the starting end drive shaft 331 to rotate. Since the second sprockets 332 on adjacent drive shafts 331 are connected by the second chain 333, the rotation of the starting end drive shaft 331 will drive all drive shafts 331 to rotate synchronously. The drive shaft 331 drives the third feeding roller 330 to rotate, realizing the conveying and precise positioning of the workpiece on the turntable 310.

[0042] Example 6: Figure 1 and Figure 2The automatic positioning component includes a base plate 300, which is fixedly mounted on the inner wall of the first frame 100. The top of the base plate 300 is rotatably connected to a turntable 310 via a second rotating shaft. A third stepper motor for driving the second rotating shaft is fixedly mounted on the inner wall of the base plate 300. The turntable 310 has inlet and outlet ports 320 at its front and rear ends. A third feeding roller 330 is rotatably connected to the inner wall of the turntable 310 via bearings. Several third feeding rollers 330 are provided. A drive shaft 331 is provided in the middle of the third feeding roller 330. A second sprocket 332 is fixedly mounted on the outer wall of the drive shaft 331. Adjacent second sprockets 332 are sequentially connected by a second chain 333. A second servo motor 340 is fixedly installed on the inner wall of the top of the turntable 310. The outer wall of the output shaft of the second servo motor 340 is connected to the outer wall of the starting drive shaft 331 through a second sprocket 332 and a second chain 333. The second frame 400 is fixedly connected to the side wall of the first frame 100. The second frame 400 and the first frame 100 are perpendicularly distributed. A third servo motor 420 is fixedly installed on the side wall of the second frame 400. The output shaft of the third servo motor 420 is connected to the outer wall of the third feed roller 410 through a third sprocket and a third chain. Adjacent third feed rollers 410 are sequentially connected through a third sprocket and a third chain.

[0043] The specific application scenario of this embodiment is as follows: After the third servo motor 420 starts, its output shaft transmits power to the third feeding roller 410 through the third sprocket and the third chain, causing the third feeding roller 410 to rotate. Since adjacent third feeding rollers 410 are also connected by the third sprocket and the third chain, all third feeding rollers 410 will rotate synchronously. The second frame 400 is perpendicularly distributed to the first frame 100. After the visual inspection and recognition camera 150 has inspected the workpiece, the control system controls the start, stop, and direction of the sorting feeder according to the inspection result. If the workpiece is qualified, it is conveyed to one direction; if it is unqualified, it is conveyed to another direction, thereby realizing the automatic sorting of workpieces.

[0044] The working principle of this utility model is as follows: When used by those skilled in the art, the main feeder is driven by the first servo motor 120 and the first chain transmission to realize workpiece conveying. The pneumatic clamping assembly clamps the workpiece from both sides through the cylinder 210 and the push plate 220, moving the workpiece to a suitable feeding position for feeding, ensuring stable positioning. The visual detection and recognition camera 150 adjusts the angle through the first step motor and the second step motor 160, collects workpiece images and analyzes them. The turntable 310 is driven to rotate by the third step motor. The second servo motor 340 drives the third feeding roller 330 through chain transmission to accurately adjust the workpiece orientation. The feeding roller 410 is driven by the third servo motor 420 to divert the workpiece according to the detection results. All components are driven by the third chain transmission and servo control to realize high-precision automated quality inspection and sorting.
