Description

Technical Field

[0001] The present invention relates to the technical field of diffusion plates, and more specifically, to a detection device for a diffusion plate. Background Art

[0002] A diffusion plate is a material used in optical and lighting applications. Its main function is to evenly distribute the light emitted by a light source, thereby avoiding light spots and glare and providing a uniform and soft lighting effect. Diffusion plates are commonly used in fields such as LED lighting devices, display screens, and optical instruments.

[0003] During the production process of diffusion plates, quality inspection is required. The detection of diffusion plates usually uses a high-resolution industrial line-scan CCD camera to scan and image the product in cooperation with an on-line scanning light source, and automatic detection is carried out based on a dedicated image processing software on an industrial computer, which can effectively detect the quality of the product. However, the existing diffusion plate detection devices often make misjudgments due to dirt on the surface of the diffusion plate, resulting in the rejection of originally good products, thereby reducing the yield rate. Therefore, it is necessary to propose a detection device for diffusion plates to solve the above problems. Summary of the Invention

[0004] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a detection device for a diffusion plate, which can solve the problem that the existing diffusion plate detection device cannot pre-treat the dirt on the surface of the diffusion plate, thereby reducing the interference of external factors on the detection accuracy.

The bottom ends of the two second electric push rods on the same side of the suspension rail are installed on the top surface of the same pressing plate. A side plate is fixed to the outside of each pressing plate, and a camera is installed inside the side plate.

[0013] As a preferred embodiment of the present invention, a transmission mechanism is installed on the top surface of the bearing beam. The transmission mechanism includes a top box fixed to the top surface of the bearing beam. There are sliding grooves on both sides of the top box. Two extrusion heads are symmetrically fixed to both sides of the top box. A sliding rod is slidably connected inside the bearing beam. A third spring is sleeved on the sliding rod.

[0014] As a preferred embodiment of the present invention, a cutting mechanism is provided inside the bearing beam.

[0016] As a preferred embodiment of the present invention, a workpiece mechanism is installed inside the installation groove. The workpiece mechanism includes a fixed ear inserted into the inside of the installation groove, and a plate body is fixed to the bottom end of the fixed ear.

[0017] Compared with the prior art, the advantages of the present invention are as follows:

[0018] While the second electric push rod drives the camera to reach the visual inspection position, the lower sliding plate is pressed down by the pressing plate. The lower sliding plate can not only drive the cleaning brush to slide out of the housing and abut against the surface of the plate body, but also drive the housing to descend, thereby driving the cleaning brush to longitudinally wipe the surface of the plate body and cleaning both sides of the plate body simultaneously. The cleaning brush can complete the cleaning of the plate body before the camera reaches the visual inspection position, and when the camera reaches the position, the cleaning mechanism can completely disengage from the plate body, avoiding blocking the plate body, ensuring the integrity of the camera visual inspection, and improving the detection accuracy.

[0019] During the downward sliding process of the housing, the sinking mechanism is driven to slide in the through groove. By using the intermittent abutment of the extrusion block against the convex block during the sliding process of the sinking mechanism, the inner sliding plate is driven to reciprocate inside the sinking rod. Then, by using the cooperation of the dial plate and the connecting block, the cleaning brush is driven to slide horizontally through the inner sliding plate. That is, while the cleaning brush is driven to slide downward by the housing, it slides horizontally back and forth, increasing the brushing method of the cleaning brush, with better cleaning effect and higher cleaning efficiency.

[0020] After the visual inspection is completed, the cleaning mechanism drives the sinking mechanism to reset. During the resetting process of the sinking mechanism, the slide bar can also be driven up by the drag plate. The slide bar drives the swing plate to swing through the push plate at its bottom. During the swinging process of the swing plate, the push block is pushed to slide, thereby driving the cutter to cut the fixed ear, separate the fixed ear from the plate body, and quickly complete the release of the plate body by the load-bearing mechanism.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment 1. Please refer to Figures 1-11 As shown, the present invention discloses a detection device for a diffusion plate, including a bearing mechanism 1. The bearing mechanism 1 includes a bearing beam 11, and two installation grooves 18 are symmetrically arranged at the bottom of the bearing beam 11;

[0036] A detection mechanism 3 is arranged above the bearing beam 11. The detection mechanism 3 includes second electric push rods 33 installed on both sides of the bearing beam 11, and a pressing plate 34 is installed at the bottom end of the second electric push rods 33;

[0037] Cleaning mechanisms 6 are installed on both sides of the bearing beam 11. The cleaning mechanism 6 includes an outer shell 61 slidably connected to both sides of the bearing beam 11. A lower sliding plate 63 is slidably connected to the outside of the outer shell 61. A support plate 67 is installed inside the outer shell 61. A trapezoidal block 65 is fixed to one side of the support plate 67. The lower sliding plate 63 abuts against the inclined surface of the trapezoidal block 65, and a cleaning brush 691 is slidably installed on the other side of the support plate 67.

[0038] After the load beam 11 transports the workpiece mechanism 7 to the detection area of the detection mechanism 3 and stops moving, the second electric push rod 33 is then activated to drive the pressing plate 34 to move downward (in the orientation shown in the attachment). Figure 1 During the downward movement of the pressing plate 34, it first pushes the lower slide plate 63 downward. The lower slide plate 63 slides downward within the outer shell 61, squeezing the trapezoidal block 65. The trapezoidal block 65 drives the support plate 67 to slide towards the load beam 11. The support plate 67 drives the cleaning brush 691 to slide. Since the outer shell 61 is attached to both sides of the load beam 11 at this time, the cleaning brush 691 cannot slide out of the outer shell 61. Instead, the downward pressure of the pressing plate 34 drives the outer shell 61 to slide downward through the lower slide plate 63, disengaging from the load beam 11. And as the second electric push rod 33 extends, the outer shell 61 continues to move downward at a constant speed. Losing the resistance from the side of the load beam 11 against the cleaning brush 691, the cleaning brush 691 slides out of the inner part of the outer shell 61 and then contacts the surface of the plate body 71. By using the second electric push rod 33 to drive the outer shell 61 to descend, the cleaning brush 691 wipes the surface of the plate body 71, removing the dirt on the surface of the plate body 71 to prevent the dirt from affecting subsequent quality inspections.

[0039] Embodiment 2 is an explanatory description based on Embodiment 1. Specifically, please refer to Figures 1-11 The detection mechanism 3 further includes a suspension rail 31 installed above the load beam 11. The linear motor 14 is slidably connected to the suspension rail 31. A number of support rods 32 are symmetrically fixed on both sides of the suspension rail 31. The bottom end of each support rod 32 is installed with a second electric push rod 33. The bottom ends of the two second electric push rods 33 on the same side of the suspension rail 31 are installed on the top surface of the same pressing plate 34. A side plate 35 is fixed on the outside of each pressing plate 34, and a camera 36 is installed on the inner side of the side plate 35.

[0040] The cleaning mechanism 6 further includes a side groove 62 provided on the outside of the outer shell 61. The lower slide plate 63 is slidably connected to the inside of the side groove 62. Two sixth springs 64 are symmetrically installed on the top surface of the lower slide plate 63. Two seventh springs 66 are symmetrically installed on the side surface of the trapezoidal block 65. An adjustment groove 68 is provided on the other side of the support plate 67. Two eighth springs 69 are symmetrically installed at both ends inside the adjustment groove 68. An inner slide bar 692 is fixed on the side surface of the cleaning brush 691. The inner slide bar 692 is slidably connected to the inside of the adjustment groove 68, and the two eighth springs 69 respectively abut against both ends of the inner slide bar 692. Two connecting blocks 693 are symmetrically fixed at both ends of the top surface of the cleaning brush 691, and each connecting block 693 abuts against the corresponding dial plate 27.

[0041] The workpiece mechanism 7 is installed inside the installation groove 18. The workpiece mechanism 7 includes a fixing ear 72 inserted into the inside of the installation groove 18, and a plate body 71 is fixed at the bottom end of the fixing ear 72.

[0042] Currently, in the production process of the plate body 71, the plate body 71 is usually transferred by horizontal conveying and sucker adsorption. However, this method will increase the processing procedures and raise the production cost in the processes of forming and processing (such as bending, punching, etc.), cleaning and drying, and quality inspection of the plate body 71. For example, when using a roller conveyor or a sucker to transfer the plate body 71, the cleaning equipment can only clean one side of the plate body 71, and the other side needs to be turned over to be cleaned; during inspection, the roller conveyor or the sucker will block the plate body 71, creating dead angles and resulting in inaccurate inspection. Therefore, to solve the above problems, a fixed ear 72 is designed on one side of the plate body 71 in the present invention. During transportation, the fixed ear 72 is inserted into the corresponding installation groove 18 at the bottom of the bearing beam 11. The first electric push rod 19 inside the installation groove 18 is activated to drive the clamping plate 191 to clamp the fixed ear 72, thereby vertically fixing the plate body 71, facilitating the cleaning mechanism 6 to clean both sides of the plate body 71 simultaneously, and the method of clamping the fixed ear will not block the plate body 71, making the detection by the camera 36 more accurate.

[0043] When transporting the plate body 71, the linear motor 14 travels on the suspension rail 31 and is connected to the bearing beam 11 through the long rod 15. The linear motor 14 drives the bearing beam 11 and other mechanisms installed thereon to move together, thereby achieving the purpose of transporting the plate body 71.

[0044] After the bearing beam 11 transports the plate body 71 to the detection area as shown in the appendix Figure 1 After that, the second electric push rod 33 is activated to drive the pressing plate 34 to descend. The pressing plate 34 drives the lower sliding plate 63 to descend. The lower sliding plate 63 slides downward inside the outer shell 61, stretching the sixth spring 64, and at the same time squeezing the trapezoidal block 65. The trapezoidal block 65 drives the support plate 67 to slide towards the bearing beam 11, stretching the seventh spring 66. The support plate 67 drives the cleaning brush 691 to slide. Since the outer shell 61 is attached to both sides of the bearing beam 11 at this time, the cleaning brush 691 cannot slide out of the outer shell 61. However, the downward pressure of the pressing plate 34 drives the outer shell 61 to slide downward, disengaging from the bearing beam 11, and as the second electric push rod 33 extends, the outer shell 61 continues to move downward at a constant speed. Losing the resistance of the side of the bearing beam 11 against the cleaning brush 691, the cleaning brush 691 slides out of the inner part of the outer shell 61 and then contacts the surface of the plate body 71. By using the second electric push rod 33 to drive the outer shell 61 to descend, the cleaning brush 691 wipes the surface of the plate body 71, removing the dirt on the surface of the plate body 71 to prevent the dirt from affecting the subsequent quality inspection.

[0045] During the process of the second electric push rod 33 driving the pressing plate 34 to descend, the pressing plate 34 also drives the side plate 35 to descend. When the outer shell 61 slides below the bottom end of the plate body 71 (the outer shell 61 does not block the plate body 71), the second electric push rod 33 stops extending. At this time, the camera 36 inside the side plate 35 reaches the detection position and starts visual sampling.

[0046] Initially, the cleaning mechanism 6 is attached to both sides of the bearing beam 11, and the cleaning brush 691 is hidden inside the housing 61. This can not only prevent the entire cleaning mechanism 6 from blocking the baffle 71 when not in use, thus affecting the visual inspection by the camera 36, but also protect the cleaning brush 691 from external environmental pollution during transportation.

[0047] Embodiment 3. This embodiment is an explanatory description based on Embodiment 1. Specifically, please refer to Figures 1-11 , the bearing mechanism 1 further includes four through grooves 12 penetrating through the four corners of the bearing beam 11. The bottom ends of the two suspension rods 13 are symmetrically fixed to the top surface of the bearing beam 11. The top ends of the two suspension rods 13 are equipped with linear motors 14. A number of long rods 15 are symmetrically installed on the top surface of the bearing beam 11. A first spring 16 is sleeved on each long rod 15. An extrusion block 17 is fixed to the inner side of each through groove 12. Two first electric push rods 19 are symmetrically installed on both sides of each installation groove 18. A clamping plate 191 is installed at the output end of each first electric push rod 19.

[0048] A sinking mechanism 2 is arranged in the through groove 12. The sinking mechanism 2 includes a sinking rod 21 slidably connected to each through groove 12. The top ends of the two sinking rods 21 on the long side of the bearing beam 11 are fixedly connected with a cross bar 22. A drag plate 23 is fixed to the side wall of the cross bar 22. An inner sliding plate 24 is slidably connected inside the sinking rod 21. A number of convex blocks 25 are equidistantly fixed to one side of the inner sliding plate 24. A number of second springs 26 are equidistantly installed on the other side of the inner sliding plate 24. The inner sliding plate 24 is elastically connected to the inside of the corresponding sinking rod 21 through a number of second springs 26. A dial plate 27 is fixed to the bottom end of the inner sliding plate 24.

[0049] During the process that the cleaning brush 691 slides out of the housing 61 and contacts the surface of the baffle 71, the cleaning brush 691 drives the connecting blocks 693 at both ends thereof to slide together. The connecting blocks 693 slide along the side surface of the dial plate 27. No matter how the connecting blocks 693 slide, they always contact the side surface of the dial plate 27.

[0050] During the descent of the shell 61, the sinking mechanism 2 is driven to descend, and the sinking rod 21 slides in the corresponding through groove 12. The sinking rod 21 drives the cross bar 22 to descend, and the cross bar 22 drives the drag plate 23 to descend. A number of long rods 15 arranged on the top surface of the load-bearing beam 11 penetrate the cross bar 22, and the top end of the first spring 16 sleeved on the outer wall of the long rod 15 contacts the bottom surface of the cross bar 22. During the descent of the cross bar 22, the cross bar 22 and the long rod 15 slide relative to each other, and the cross bar 22 compresses the first spring 16. The long rod 15 can improve the stability of the sinking mechanism 2 during sliding and reduce shaking. Multiple second springs 26 arranged inside the sinking rod 21 push the inner slide 24 toward the outside of the sinking rod 21, so that the protrusion 25 on one side of the inner slide 24 protrudes from the side of the sinking rod 21, and the two groups of protrusions 25 at both ends of the same cross bar 22 are staggered and fixed on their respective inner slides 24. When the sinking rod 21 slides downward in the through groove 12, the extrusion blocks 17 on the inside of the through groove 12 successively resist the protrusions 25 on the side of the inner slide 24, thereby intermittently pushing the inner slide 24 into the sinking rod 21, and cooperating with the elastic force of the second spring 26, the inner slide 24 reciprocates in the sinking rod 21, and the two inner slides 24 at both ends of the same cross bar 22 move in the same direction at the same time.

[0051] In this way, the bottom ends of the two inner slides 24 inside the same shell 61 drive their respective paddles 27 to reciprocate at the same frequency. The paddle 27 pushes the connecting block 693, thereby driving the cleaning brush 691 to swing horizontally. The connecting block 693 drives the inner slide bar 692 on its side to swing left and right in the adjustment groove 68, alternately compressing and releasing the eighth spring 69 inside the adjustment groove 68. The horizontal swing of the cleaning brush 691 can form a horizontal wiping of the plate body 71, and cooperate with the shell 61 to drive the cleaning brush 691 to wipe the plate body 71 vertically downward, thereby increasing the movement mode of the cleaning brush 691 and improving the cleaning effect.

[0052] Example 4: This example is an explanation based on Example 1. For details, please refer to Figures 1-11 A transmission mechanism 4 is installed on the top surface of the load-bearing beam 11, and the transmission mechanism 4 includes a top box 41 fixed to the top surface of the load-bearing beam 11, and slide grooves 42 are provided on both sides of the top box 41. Two extrusion heads 43 are symmetrically fixed on both sides of the top box 41. A slide rod 44 is slidably connected to the inside of the load-bearing beam 11, and a third spring 45 is sleeved on the slide rod 44. A push plate 46 is fixed to the bottom end of the slide rod 44, and a shell 47 is fixed to the top end of the slide rod 44. Two fourth springs 48 are symmetrically installed inside the shell 47, and two shift blocks 49 are symmetrically slidably connected to both sides of the shell 47, and one end of the two fourth springs 48 is respectively installed on the side of the corresponding shift block 49, and the shift block 49 is slidably connected to the inside of the corresponding slide groove 42.

[0053] The inside of the bearing beam 11 is provided with a cutting mechanism 5. The cutting mechanism 5 includes two swing plates 51 symmetrically and rotatably connected to the inside of the bearing beam 11. The swing plates 51 are elastically connected to the inside of the bearing beam 11 through torsion springs 52. A wedge block 53 is fixed to the top end of each swing plate 51. The two ends of the push plate 46 respectively abut against the two wedge blocks 53. Two push blocks 54 are symmetrically and slidably connected to the inside of the bearing beam 11. And the bottom end of each swing plate 51 respectively abuts against the outer side of the corresponding push block 54. A connecting rod 55 is fixed to the bottom end of each push block 54. Cutting knives 56 are installed at both ends of the connecting rod 55. And the cutting knives 56 are located in the installation groove 18. A fifth spring 57 is installed on the side surface of the connecting rod 55. The connecting rod 55 is elastically connected to the inside of the bearing beam 11 through the fifth spring 57.

[0054] The cross bar 22 follows the cleaning mechanism 6 to descend. When the outer shell 61 reaches the bottom end of the plate body 71 and continues to descend to leave the side range of the plate body 71, the drag plate 23 on the side surface of the cross bar 22 abuts against the dial block 49 protruding from the sliding groove 42. Since the contact surfaces of the drag plate 23 and the dial block 49 in this process are both inclined surfaces (that is, the end of the drag plate 23 is an inclined surface, the top surface of the end of the dial block 49 is an inclined surface, and the inclined surfaces of the two are mutually adapted), the drag plate 23 pushes the dial block 49 into the shell body 47 after abutting against the dial block 49. The dial block 49 compresses the fourth spring 48 inside the shell body 47. Thus, the drag plate 23 can easily cross the obstruction of the dial block 49. Finally, the drag plate 23 slides to the lower part of the dial block 49, and the dial block 49 pops out of the shell body 47 again.

[0055] After the cleaning mechanism 6 finishes cleaning, the camera 36 performs visual inspection. After the inspection is completed, the linear motor 14 drives the plate body 71 to continue moving through the bearing beam 11. The pressing plate 34 and the lower sliding plate 63 slide relative to each other. When the lower sliding plate 63 is separated from the abutment of the pressing plate 34, the seventh spring 66 pushes the trapezoidal block 65, so that the support plate 67 and the cleaning brush 691 are reset. The lower sliding plate 63 is pulled back upward by the sixth spring 64; without the abutment of the pressing plate 34 on the lower sliding plate 63, the elastic force of the first spring 16 pushes the cross bar 22 upward, and the entire sinking mechanism 2 slides upward and finally returns to the initial position. The sinking mechanism 2 also drives the outer shell 61 back to both sides of the bearing beam 11.

[0056] At the beginning of the upward movement of the cross bar 22, the platen 23 abuts against the bottom surface of 49, thereby driving the housing 47 to slide inside the top box 41. As the housing 47 slides upward, the slider 49 slides upward within the chute 42. The housing 47 drives the push plate 46 to slide upward through the slide bar 44, and compresses the third spring 45. As the push plate 46 slides upward, it abuts against and pushes the wedge blocks 53 at both ends away from itself. The wedge blocks 53 drive the swing plate 51 to swing. As the swing plate 51 swings, the torsion spring 52 stores energy. At the same time, its bottom end pushes the push block 54 inward. The push block 54 drives the cutting knives 56 to move closer to each other through the connecting rod 55. The cutting knives 56 cut off the fixing ears 72 inside the installation groove 18, causing the plate body 71 to fall off, completing the entire inspection process of the plate body 71. After the cutting knives 56 complete the cutting, the platen 23 drives the slider 49 to just rise to the top end of the chute 42. During this process, the extrusion head 43 on the top side of the top box 41 abuts against and extrudes the slider 49, pushing the slider 49 into the housing 47. The slider 49 is separated from the platen 23. Losing the blockage of the slider 49 to the platen 23, the entire sinking mechanism 2 continues to rise with the cleaning mechanism 6 until the sinking mechanism 2 and the cleaning mechanism 6 are reset. During the reset process of the sinking mechanism 2 and the cleaning mechanism 6, the first electric push rod 19 drives the first electric push rod 19 to retract, releasing the fixing ears 72 inside the installation groove 18.
