Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of injection molding production, in particular to an unmanned intelligent mold monitor for monitoring molds in an injection molding workshop. Background Art
[0002] In the injection molding production process, it is necessary to monitor the working conditions of the injection molding machine in real time to avoid the problem of equipment no-load caused by product shortage, as well as mold damage and product defects caused by reasons such as ejector failure to return to position, fixed mold adhesion on the product, abnormal embedding of inserts, offset feeding position, inadequate return of the robot, and foreign matter mixed in the feeding. At present, the industry mainly uses cameras and light sources to collect the working images of the injection molding machine and analyze them in real time to respond to equipment abnormalities in a timely manner. Constrained by the structure of the injection molding machine, the light source and camera are mostly installed at specific positions on the injection molding machine. The camera can only collect images of specific parts of the injection molding machine. In order to fully obtain the working images of the injection molding machine, it is necessary to arrange multiple cameras on the injection molding machine, which will increase the monitoring cost of the injection molding machine. In addition, since the position of the light source is fixed, when the light emitted by the light source is irradiated on the surface of the injection molding machine, reflections are likely to appear in local positions, which in turn affects the quality of the collected images, reducing the reliability of the injection molding machine image monitoring. In addition, because the camera and light source are mostly set above the injection molding machine mold during image acquisition, when the mold needs to be replaced, the camera and light source need to be removed first and then replaced. The mold replacement workload is large, which in turn affects the mold replacement efficiency. Utility Model Content

[0023] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.
[0024] Please combine Figure 1 , Figure 2 as well as Figure 5The utility model discloses an unmanned intelligent mold monitor that can fully collect mold images and has low monitoring cost, adjustable light source position to reduce reflection problems, and easy mold replacement. The monitor includes a bracket 100, a position and posture adjustment unit 200, and an industrial computer 300. The bracket 100 is used to support and raise the height of the remaining components so that the unmanned intelligent mold monitor can collect images from above the mold to reduce the obstruction of the image collection part by external components and the mold itself. The bracket 100 is installed on the side of the injection molding machine mold. In this embodiment, the bracket 100 can be fixed on the injection molding machine or set on the side of the injection molding machine. The position and posture adjustment unit 200 includes a first control box 210 and a second control box 220 which are arranged side by side and slidably mounted on the top of the bracket 100, a first arm 230 which passes through the first control box 210 and can be close to or away from the bracket 100, a first driving mechanism 240 which is accommodated in the first control box 210 and drives the first arm 230 to move relative to the first control box 210, a light source 400 which is suspended above the mold and connected to the end of the first arm 230, a first rotating driving mechanism 250 which is fixed at the end of the first arm 230 and drives the light source 400 to rotate in a vertical plane, a second arm 260 which passes through the second control box 220 and can be close to or away from the bracket 100, a second driving mechanism 270 which is accommodated in the second control box 220 and drives the second arm 260 to move relative to the second control box 220, a camera 500 which is suspended above the mold and connected to the end of the second arm 260, and a second rotating driving mechanism 280 which is fixed at the end of the second arm 260 and drives the camera 500 to rotate in a vertical plane. The first rotary drive mechanism 250 and the second rotary drive mechanism 280 are both rotary motors. Among them, the first control box 210, the first arm 230, the first drive mechanism 240 and the first rotary drive mechanism 250 constitute the light source control part of the position and posture adjustment unit 200, and the second control box 220, the second arm 260, the second drive mechanism 270 and the second rotary drive mechanism 280 constitute the camera control part of the position and posture adjustment unit 200. The industrial computer 300 is fixed on the bracket 100 and is electrically connected to the first drive mechanism 240, the light source 400, the first rotary drive mechanism 250, the second drive mechanism 270, the camera 500, the second rotary drive mechanism 280 and the injection molding machine controller respectively.
[0025] During the operation of the above monitor, the industrial computer 300 controls the first driving mechanism 240 and the second driving mechanism 270 to work according to the position of the part to be imaged on the mold, so as to adjust the horizontal position of the light source 400 and the camera 500, so that the light source 400 and the camera 500 reach the designated part above the mold; then the industrial computer 300 controls the first rotating driving mechanism 250 and the second rotating driving mechanism 280 to adjust the rotation angle of the light source 400 and the camera 500 respectively, so as to adjust the posture of the light source 400 and the camera 500, so as to avoid the blind spot of the viewing angle on the mold, and at the same time, the angle adjustment of the light source 400 can avoid the reflection problem on the mold surface caused by the light source 400 directly shining on the designated part on the mold, thereby improving the quality of the collected mold image. After collecting the image of the preset part on the mold, the camera 500 transmits the image to the industrial computer 300 for further processing, so as to achieve the purpose of real-time monitoring of the working condition of the injection molding machine. When the image processing module in the industrial computer 300 determines that the image is abnormal, that is, the working condition of the injection molding machine is abnormal, the industrial computer 300 sends an electrical signal to the injection molding machine controller to control the injection molding machine to stop, so as to respond to the abnormal situation of the injection molding machine in time. For example, when it is detected that the product is out of material, the feeding position is offset, there are foreign objects in the feeding of the stamping machine, the robot return device is not in place, the ejector is not returned, the product is missing from the moving mold due to product adhesion, and the insert is abnormally embedded, the industrial computer 300 will alarm and control the injection molding machine to stop.
[0026] In one embodiment, the bracket 100 includes two columns 110 arranged opposite to each other and guide rails 120 respectively fixedly connected to the tops of the two columns 110. The columns 110 are fixed to the injection molding machine platform or the frame beside the injection molding machine by bolts, and the entire bracket 100 is in an N-shaped structure. The bottom of the first control box 210 is fixedly connected to a first slider 211 that slides with the guide rail 120, and the bottom of the second control box 220 is fixedly connected to a second slider 221 that slides with the guide rail 120. The first arm 230 and the second arm 260 are arranged in parallel at intervals, and the length direction of the first arm 230 and the length direction of the second arm 260 are respectively perpendicular to the length direction of the guide rail 120. In this way, the first control box 210 and the second control box 220 can be moved along the length direction of the guide rail 120 under the push of external force. On the one hand, the horizontal position of the camera 500 and the light source 400 relative to the mold can be adjusted to shorten the distance from the camera 500 to the part of the mold to be imaged. On the other hand, the relative position adjustment between the light source 400 and the mold can be realized to avoid the problem of image acquisition being interfered by light due to the light source 400 being too close to the mold, and to avoid the problem of insufficient brightness of the mold surface and insufficient clarity of the collected image due to the light source 400 being too far from the mold. In order to realize automatic adjustment of the positions of the light source 400 and the camera 500 in the horizontal plane, the position and posture adjustment unit 200 also includes a third driving mechanism fixed on the guide rail 120 and driving the first control box 210 to slide along the length direction of the guide rail 120, and a fourth driving mechanism fixed on the guide rail 120 and driving the second control box 220 to slide along the length direction of the guide rail 120. The third driving mechanism and the fourth driving mechanism can be cylinders or electric cylinders. The output end of the third driving mechanism is fixedly connected to the outer surface of the first control box 210 to push the first control box 210 to slide on the guide rail 120; the output end of the fourth driving mechanism is fixedly connected to the outer surface of the second control box 220 to push the second control box 220 to slide on the guide rail 120.
[0027] Please combine Figure 1-4In one embodiment, a first rack structure 231 is provided on the first arm 230 along its length direction, and the first driving mechanism 240 includes a first rotating motor 241 accommodated in the first control box 210 and fixedly connected to the inner wall of the first control box 210, and a first gear 242 fixed on the output shaft of the first rotating motor 241 and meshing with the first rack structure 231. In this way, when controlling the light source 400 to approach or move away from the bracket 100, the industrial computer 300 controls the first rotating motor 241 to work, and the output shaft of the first rotating motor 241 will drive the first gear 242 to rotate. Since the first gear 242 is engaged with the first rack structure 231, during the rotation of the first gear 242, each part on the first rack structure 231 is engaged with the first gear 242 one by one, and the first arm 230 moves relative to the first control box 210, so that the light source 400 fixed at the end of the first arm 230 and the first rotating drive mechanism 250 gradually approach or move away from the first control box 210, thereby realizing the position adjustment of the light source 400 along the length direction of the first arm 230.
[0028] Please combine Figure 1 as well as Figure 5-7 , a second rack structure 261 is provided on the second arm 260 along its length direction, and the second driving mechanism 270 includes a second rotary motor 271 housed in the second control box 220 and fixedly connected to the inner wall of the second control box 220, and a second gear 272 fixed on the output shaft of the second rotary motor 271 and meshed with the second rack structure 261. In this way, when controlling the camera 500 to approach or move away from the bracket 100, the industrial computer 300 controls the second rotary motor 271 to work, and the output shaft of the second rotary motor 271 will drive the second gear 272 to rotate. Since the second gear 272 is meshed with the second rack structure 261, during the rotation of the second gear 272, each part of the second rack structure 261 is meshed with the second gear 272 one by one, and the second arm 260 moves relative to the second control box 220, so that the camera 500 fixed at the end of the second arm 260 and the second rotary driving mechanism 280 gradually approach or move away from the second control box 220, so as to achieve the position adjustment of the camera 500 along the length direction of the second arm 260.
[0029] Furthermore, the position and posture adjustment unit 200 also includes a first mounting frame 232 and a second mounting frame 262, a first U-shaped groove is opened on the top of the first mounting frame 232, the end of the first arm 230 is embedded in the first U-shaped groove and is screwed to the first mounting frame 232, the first rotation drive mechanism 250 and the light source 400 are located on both sides of the first mounting frame 232, and the first rotation drive mechanism 250 is fixedly connected to the first mounting frame 232; a second U-shaped groove is opened on the top of the second mounting frame 262, the end of the second arm 260 is embedded in the second U-shaped groove and is screwed to the second mounting frame 262, the second rotation drive mechanism 280 and the camera 500 are located on both sides of the second mounting frame 262, and the second rotation drive mechanism 280 is fixedly connected to the second mounting frame 262. In this embodiment, at least one first mounting groove 233 extending along the length direction of the first arm 230 is formed on both opposite outer side walls of the first machine arm 230, and at least one second mounting groove 263 extending along the length direction of the second machine arm 260 is formed on both opposite outer side walls of the second machine arm 260. In this way, the first mounting frame 232 can be fixed to the first machine arm 230 by passing through the side wall of the first U-shaped groove and inserting the bolts of the first mounting groove 233, and after the bolts are tightened and abut against the bottom of the first mounting groove 233; similarly, the second mounting frame 262 can be fixed to the second machine arm 260 by passing through the side wall of the second U-shaped groove and inserting the bolts of the second mounting groove 263, and after the bolts are tightened and abut against the bottom of the second mounting groove 263.
[0030] In order to improve the reliability of position adjustment of the light source 400 and the camera 500 in the horizontal plane, a first guide block 212 is fixed in the first control box 210, a first limiting groove is opened on the first guide block 212, and a first limiting rail 213 is provided on the first arm 230, which extends along its length direction and is embedded in the first limiting groove to slide with the first guide block 212; a second guide block 222 is fixed in the second control box 220, a second limiting groove is opened on the second guide block 222, and a second limiting rail 223 is provided on the second arm 260, which extends along its length direction and is embedded in the second limiting groove to slide with the second guide block 222. Through the cooperation of the first guide block 212 and the first limiting rail 213, while the first driving mechanism 240 guides and drives the first arm 230, the first guide block 212 supports and limits the first arm 230, thereby reducing the shaking generated during the movement of the first arm 230; through the cooperation of the second guide block 222 and the second limiting rail 223, while the second driving mechanism 270 guides and drives the second arm 260, the second guide block 222 supports and limits the second arm 260, thereby reducing the shaking generated during the movement of the second arm 260. Preferably, the first limiting rail 213 is fixed on the lower surface of the first arm 230, and the first rack structure 231 is fixed on the upper surface of the first arm 230. In this way, the first arm 230 is jointly constrained by the first gear 242 and the first guide block 212 to reduce the vertical shaking of the first arm 230; the second limiting rail 223 is fixed on the lower surface of the second arm 260, and the second rack structure 261 is fixed on the upper surface of the second arm 260. In this way, the second arm 260 is jointly constrained by the second gear 272 and the second guide block 222 to reduce the vertical shaking of the second arm 260.
[0031] In another embodiment, the first arm 230 and the second arm 260 are both screw rods, and the first driving mechanism 240 includes a first nut housed in the first control box 210 and threadedly mounted on the first arm 230, and a third rotating motor located next to the first nut, a third gear is fixed on the output shaft of the third rotating motor, and a first gear ring is provided on the outer surface of the first nut to mesh with the gear teeth of the third gear; the second driving mechanism 270 includes a second nut housed in the second control box 220 and threadedly mounted on the second arm 260, and a fourth rotating motor located next to the second nut, a fourth gear is fixed on the output shaft of the fourth rotating motor, and a second gear ring is provided on the outer surface of the second nut to mesh with the gear teeth of the fourth gear. In this way, when the position of the light source 400 needs to be adjusted, the industrial computer 300 controls the third rotating motor to work, and the output shaft of the third rotating motor drives the third gear to rotate. The third gear and the first gear ring on the outer surface of the first nut are engaged with each other, so that the first nut rotates. Since the first nut is threadedly connected to the lead screw used as the first arm 230 and the third rotating motor is fixed, during the operation of the third rotating motor, the first arm 230 will be close to or away from the first control box 210 under the threaded cooperation with the first nut, thereby realizing the position adjustment of the light source 400. Similarly, when the position of the camera 500 needs to be adjusted, the industrial computer 300 controls the fourth rotating motor to work, and the output shaft of the fourth rotating motor drives the fourth gear to rotate. The second nut is rotated through the mutual engagement of the fourth gear and the second gear ring on the outer surface of the second nut. Since the second nut is threadedly connected to the lead screw used as the second arm 260 and the fourth rotating motor is fixed, during the operation of the fourth rotating motor, the second arm 260 will be close to or away from the second control box 220 under the threaded cooperation between it and the second nut, thereby realizing the position adjustment of the camera 500.
[0032] It should be noted that, in this embodiment, the light source 400 includes a Fresnel lens array, that is, the light source 400 of this embodiment is actually a Fresnel lens array light source. After the light emitted by the light source 400 is refracted by the Fresnel lens array, it can output high-uniformity, high-brightness output light, which can minimize the mirror reflection on the mold surface, and further improve the reflection problem of the image collected by the camera 500. In addition, the camera 500 of this embodiment is an intelligent camera with high resolution, ultra-depth imaging, and autofocus functions. It transmits the collected image information to the industrial computer 300 in the form of electrical signals, which can improve the quality of the collected image and avoid the problem of incorrect judgment of the mold working condition caused by image blur.
[0033] In addition, in this embodiment, the industrial computer 300 includes an imaging module for receiving an image signal sent by the camera 500, an image processing module connected to the imaging module and processing the image, and a management module for receiving the image processing result sent by the image processing module and sending a signal to the injection molding machine controller, the light source 400 control part, the camera 500 processing part and other external control systems. Specifically, after receiving the electrical signal sent by the camera 500, the imaging module uses a high dynamic reconstruction algorithm to process the electrical signal to reconstruct the mold image, which can further solve the reflection problem in the mold imaging process. The image processing module detects the subtle differences in the reconstructed mold image through a hierarchical monitoring algorithm, which can effectively distinguish the defects of the mold itself and the residual plastic particles in the mold, and reduce false detection and false alarm. The management module is an intelligent management system that can be integrated with MES (Manufacturing Execution System, manufacturing enterprise production process execution system), can register mold templates and related signals, switch the current mold template according to the production task, and report to the workshop management system in time when an abnormality occurs, sound an alarm and control the injection molding machine to stop; it also supports VNC remote control.
[0034] The unmanned intelligent mold monitor of the utility model is implemented, and a position and posture adjustment unit 200 is set. Through the first driving mechanism 240 and the second driving mechanism 270 and the first control box 210 and the second control box 220 are slidably installed on the top of the bracket 100, the position adjustment of the light source 400 and the camera 500 in the horizontal direction can be achieved, so that the camera 500 and the light source 400 reach above the specified position of the mold, and the position adjustment of the light source 400 and the camera 500 is achieved. When the mold is replaced, the position adjustment can be used to avoid the position, and there is no need to disassemble the camera 500 and the light source 400, thereby reducing the mold replacement workload and improving the mold replacement efficiency; through the first rotary drive The driving mechanism 250 and the second rotating driving mechanism 280 respectively drive the light source 400 and the camera 500 to rotate in the vertical plane to achieve posture adjustment of the light source 400 and the camera 500. The posture and position adjustment of the light source 400 and the camera 500 can avoid the problem of blind angle of image acquisition caused by occlusion of equipment components. The comprehensive acquisition of the mold image can be achieved through a camera 500 and a light source 400, which reduces the monitoring cost of the injection molding machine mold; in addition, by adjusting the position and posture of the light source 400, the lighting conditions of the part to be imaged on the mold can be improved, and the reflection problem of the captured image can be reduced, thereby improving the image acquisition quality and the reliability of image monitoring.
