Through optical detection principles and image processing technology, an optical imaging system is used to project light onto the glass cover plate surface through lighting equipment, and then cooperate with cameras and other equipment to capture the changed light and convert it into an image signal to detect defects on the glass surface. For example, a mobile phone glass cover plate surface defect rapid detection device disclosed in publication number CN216117285U can be used for detection work.

[0003] When conducting inspection work, the mobile phone glass cover plates are transported, and the mobile phone glass cover plates are generally placed on the transport device at a certain distance. The photographic device and the light source device used for imaging in the device have a certain service life, but during inspection, both of them will be in a state of long-term startup, and will not automatically close when located between two mobile phone glass cover plates, which reduces the overall service life of the device.

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The present invention will be further described below in conjunction with the embodiments.

[0035] Example: Refer to Figures 1 to 9 A device for quickly detecting surface defects of a glass cover plate of a smart phone comprises a transmission belt 1, two centering mechanisms 2 fixed on the transmission belt 1, a detection mechanism 4 for transmitting glass plates 5 at intervals, and a flipping mechanism 3 fixed in the transmission belt 1. The transmission belt 1 has a flipping zone, and two narrow conveyor belts are rotatably arranged in the flipping zone. The narrow conveyor belt comprises a plurality of transport rollers 11 rotatably connected to the flipping zone in the same direction and at the same speed.

[0036] It should be noted that the glass plate 5 to be inspected is placed into the conveyor belt 1 through an external loading device, and the glass plate 5 can be moved and transported on the conveyor belt 1. The centering mechanism 2 can push the glass plate 5 to move to the middle before inspection to achieve the centering purpose, prevent the glass plate 5 from shifting when moving, and facilitate subsequent inspection work. The inspection mechanism 4 can detect defects on the surface of the glass plate 5 through the existing optical photography imaging method. The imaged image will be transmitted to the computer, and the defects in the image will be automatically marked. The glass plate 5 transported by the conveyor belt 1 can be inspected without affecting the movement of the glass plate 5.

[0037] Then, in order to observe the marked defects more intuitively, when the detection mechanism 4 performs the detection, the glass plate 5 will synchronously turn over the glass plate 5 that has completed a single detection, and then prepare for a second detection. The defects on the glass plate 5 can be easily found through marking and then repaired.

[0038] Further explanation, in order to center the glass plate 5 without affecting transportation, as shown in FIG. Figure 2 As shown, the centering mechanism 2 includes two support frames 21 fixed on the transmission belt 1, two electric cylinders 22 are fixed on the upper ends of the support frames 21, and protective plates 23 are symmetrically fixed on the upper ends of the two support frames 21. A centering shell 24 is fixed to the output ends of the two electric cylinders 22 on the same side. The electric cylinders 22 will simultaneously drive the centering shell 24 to move, and the moving distances are the same, and the output ends of the electric cylinders 22 pass through the end faces of the protective plates 23 on the same side. The inner wall of the centering shell 24 is rotatably connected with a plurality of centering belts 25. When centering is achieved, the plurality of centering belts 25 will contact the glass plate 5 and push it to move, and the rotating centering belts 25 and the glass plate 5 cannot generate a large friction force, and thus will not affect the transportation of the glass plate 5 by the transmission belt 1.

[0039] To further explain, in order to turn over the transported glass sheet 5, as Figure 3 and Figure 4As shown, the flipping mechanism 3 includes a protective shell 32, and the surface of the transport roller 11 is made of soft rubber. While ensuring the friction force, the glass plate 5 will not be damaged when it falls on it. The transport roller 11 is connected by a belt drive. A motor 31 is fixed on the drive belt 1. The transport roller 11 is indirectly driven by the motor 31 to facilitate the flipping operation. A plurality of groups of flipping rollers 33 are fixed in a circumferential array on the outer surface of the protective shell 32. The distance between the two flipping rollers 33 at the outermost sides of each group is less than the width of the glass plate 5. When the protective shell 32 drives the flipping roller 33 to rotate, the flipping roller 33 can lift the glass plate 5 on the transport roller 11, and then achieve the purpose of flipping through continuous rotation. A plurality of rubber rings 34 are fixed on the outer surface of the flipping roller 33. The rubber ring 34 can increase the friction force between the glass plate 5 and the rubber ring 34. When the flipping roller 33 rotates with the protective shell 32, the rubber ring 34 can prevent the glass plate 5 from deviating to prevent it from falling during the flipping process.

[0040] Then, an open groove 35 is provided at one end of the protective shell 32, and two fixed rods 36 fixed on the transmission belt 1 are provided in the open groove 35. The inner wall of the open groove 35 is symmetrically provided with arc grooves 37. The ends of the two fixed rods 36 that are away from each other are elastically connected with movable rods 38. In order to ensure that the glass plate 5 can be turned over normally, the protective shell 32 preferably drives the flip roller 33 to rotate 180° when turning over. A driving component 39 is provided in the protective shell 32, and the driving component 39 is the driving source of the protective shell 32. When the detection mechanism 4 performs the detection work, the driving component 39 will drive the protective shell 32 to rotate, and when driving the rotation, the protective shell 32 itself cannot overcome the inertia brought by the driving component 39. The inner wall of the arc groove 37 and the surface of the movable rod 38 have a large friction force, and the arc groove 37 elastically connected with the fixed rod 36 will not affect the normal rotation of the protective shell 32, but can overcome the inertia brought by the rotation of the protective shell 32, ensuring that the protective shell 32 and the flip roller 33 can rotate 180° each time to complete the turning work;

[0041] It should be noted that the rubber ring 34 is not made of a hard material. When the glass plate 5 is turned over, it will go down. The rubber ring 34 made of a soft material can protect it and prevent the glass plate 5 from being damaged due to bumps when it is turned over.

[0042] Further, in order to drive the protective housing 32 to rotate, as Figure 5As shown, the driving assembly 39 includes a driven driving tube 391, the output end of the motor 31 is fixedly connected to one end of the driving tube 391, the driving tube 391 is connected to one of the transport rollers 11 by belt transmission, the output end of the motor 31 will drive the driving tube 391 and multiple transport rollers 11 to rotate simultaneously, a sealed shell 392 is fixed in the driving tube 391, a hollow tube 393 is fixed in the sealed shell 392, one end of the hollow tube 393 is connected to a hydraulic oil pumping device, a contact and a controller are provided between the hydraulic pumping device and the detection mechanism 4, the hydraulic pumping device and the detection mechanism 4 are started at the same time, only when the hydraulic pumping device is started to pump hydraulic oil into the hollow tube 393, can the rotating driving tube 391 drive the protective shell 32 to rotate, the outer surface of the hollow tube 393 is connected to at least one rectangular shell 394, and a piston plate 395 is radially slidably connected in the rectangular shell 394;

[0043] Then, when the hydraulic oil is pumped into the hollow tube 393, it will flow into the rectangular shell 394, pushing the piston plate 395 in the rectangular shell 394 to move. When the piston plate 395 moves to contact the inner wall of the protective shell 32, the friction between the two can drive the protective shell 32 to rotate, and the hydraulic pumping device will complete the two tasks of pumping and extraction during the power-on process. That is to say, when the detection mechanism 4 performs detection, the hydraulic pumping device will pump hydraulic oil into the hollow tube 393, and wait for the piston plate 395 therein to drive the protective shell 32 to rotate until the glass plate 5 is turned over, but the piston plate 395 will only contact the protective shell 32 briefly, and can only make the glass plate 5 rotate 90°. After it is erected, the hydraulic pumping device will extract the hydraulic oil in the hollow tube 393, and at this time the piston plate 395 will not contact the protective shell 32, but the protective shell 32 and the glass plate 5 will continue to move downward by their own gravity to achieve the purpose of turning over;

[0044] It should be noted that the connection relationship between the hydraulic pumping device and the pipeline at the connection point of the hollow tube 393 is a rotational connection. Under the premise of not affecting the rotation of the driving tube 391, the hydraulic oil can be pumped into the hollow tube 393 normally, and the starting motor 31 can drive the driving tube 391 and the transport roller 11 to rotate. The rotating transport roller 11 can transport the glass plate 5 that has completed a single inspection. When the inspection mechanism 4 inspects the last glass plate 5, the hydraulic pumping device will pump hydraulic oil into the hollow tube 393. When the hydraulic oil is pumped into the hollow tube 393, it will flow into the rectangular shell 394, and then push the piston plate 395 in the rectangular shell 394 to move. When the piston plate 395 moves to contact the inner wall of the protective shell 32, it can drive the protective shell 32 and the flip roller 33 to rotate through the friction between the two.

[0045] When the flip roller 33 and the rubber ring 34 come into contact with the glass plate 5, they will drive it to rotate. The rubber ring 34 can prevent the glass plate 5 from shifting to prevent it from falling during the flipping process. When the piston plate 395 drives the protective shell 32 to rotate a certain angle, the hydraulic pumping device extracts the hydraulic oil in the hollow tube 393. At this time, the piston plate 395 will not contact the protective shell 32. The protective shell 32 and the glass plate 5 will continue to move downward due to their own gravity. The friction between the inner wall of the arc groove 37 and the surface of the movable rod 38 overcomes the inertia brought by the protective shell 32 and the glass plate 5, ensuring that the protective shell 32 and the flip roller 33 can rotate 180° to complete the flipping work, and then be transported to the transmission belt 1 by the transport roller 11.

[0046] To further explain, in order to detect the moving glass plate 5, as Figure 6 and Figure 7 As shown, the detection mechanism 4 includes a support base 41 fixedly arranged on one side of 1, a motor 2 42 is fixed on the upper end of the support base 41, a threaded rod 43 is rotatably connected in the support base 41, the output end of the motor 2 42 is fixedly connected to the upper end of the threaded rod 43, a threaded block 44 is threadedly connected to the threaded rod 43, and the position height of the threaded block 44 can be adjusted by starting the motor 2 42, and both sides of the threaded block 44 close to the transmission belt 1 are mirror-reversed and fixed with a detection shell 45, and a scanning camera device is fixed at the lower end of the detection shell 45, and a combined light source device fixed on the transmission belt 1 is provided below the scanning camera device, wherein the combined light source device can cooperate with the scanning camera device for better imaging, and can better detect defects on the glass plate 5, which is convenient for marking work;

[0047] Then, two support plates 47 are fixed in the detection shell 45, and a double-headed motor 46 is fixed between the two support plates 47. The ends of the two support plates 47 that are away from each other are rotatably connected to a reciprocating screw 48, and the reciprocating screw 48 is fixedly connected to the output end of the double-headed motor 46. A detection component 49 is sleeved on the surface of the reciprocating screw 48. In order for the flipping mechanism 3 to be able to better flip the glass plate 5, the glass plate 5 placed on the transmission belt 1 will be placed at intervals, and the two detection components 49 are reciprocated by the reciprocating screw 48 to move in opposite directions, so that the combined light source device and the scanning camera device do not need to be started for a long time, thereby reducing the operation time of the device and reducing the use cost of the device. It should be noted that the combined light source device and the scanning camera device both have a certain service life. By reducing the start-up time of the two, the service life of the device is increased.

[0048] The detection assembly 49 and the stopper 40 cooperate with each other, and the side edge of the glass plate 5 can be detected by the detection assembly 49. Further description, in order to detect the side edge of the glass plate 5, as Figure 8As shown, the detection component 49 includes a rectangular shell 491 sleeved on the surface of the reciprocating screw rod 48, an electric cylinder 492 is fixed to one end of the rectangular shell 491 close to the support plate 47, a limit plate 493 is fixed to the output end of the electric cylinder 492, a movable block 494 is slidably connected in the rectangular shell 491, and the position of the limit plate 493 is controlled by the electric cylinder 492, so that the position of the movable block 494 and the arc plate 496 can be adjusted, an elastic member 495 is fixed between the movable block 494 and the inner wall of the rectangular shell 491, and two arc plates 496 are fixed to one end of the movable block 494 away from the elastic member 495, and one end of the movable block 494 is rotatably connected to a trigger frame 497, and one end of the detection shell 45 is fixed with two driving trigger frames 497 The rotating stopper 40 and the trigger frame 497 are fixed with a light source assembly 498 at one end away from the movable block 494. When the reciprocating screw rod 48 drives the rectangular housing 491 to move, the trigger frame 497 will contact the stopper 40 during the movement. However, since the movable block 494 and the arc plate 496 can compress the elastic member 495, only after the elastic member 495 cannot be compressed and the rectangular housing 491 continues to move the trigger frame 497 can the light source assembly 498 be driven to move. By adjusting the position of the limit plate 493, the time for the light source assembly 498 to remain vertical can be controlled. For glass plates 5 of different lengths, when the light source assembly 498 rotates to a vertical state, the scanning camera device, the combined light source device and the hydraulic oil pumping device are started at the same time.

[0049] It should be noted that, without adjusting the transport speed of the transmission belt 1, when the length of the glass plate 5 becomes shorter, the rotation time of the protective shell 32 also needs to be extended backward, otherwise the glass plate 5 cannot fully contact with the rubber ring 34. Turning over at this time will cause the glass plate 5 to fall. The threaded rod 43 is controlled to rotate by the motor 2 42 to adjust the position height of the threaded block 44 and the detection shell 45, so as to facilitate better detection of the glass plate 5. Then, the double-headed motor 46 is started to drive the two reciprocating screws 48 to rotate. The reciprocating screw 48 can drive the two rectangular shells 491 to move away from each other. When the arc plate 496 and the trigger frame 497 contact the inner wall of the detection shell 45 and the stopper 40 respectively, the arc plate 496 will push the movable block 494 to compress the elastic member 495. When the elastic member 495 is compressed to a limited size, the trigger frame 497 will drive the light source assembly 498 to rotate to a vertical direction, so that the imaging device, the combined light source device and the hydraulic oil pumping device are started at the same time to detect the glass plate 5.

[0050] Only when the light source assembly 498 is rotated to a vertical state, the contacts arranged therein will contact each other, allowing the controller to receive the model and drive the scanning camera device, the combined light source device and the hydraulic oil pumping device to start simultaneously.

[0051] The working principle of the present invention is as follows: the glass plate 5 to be inspected is placed into the conveyor belt 1 through an external loading device, and the glass plate 5 can be moved and transported on the conveyor belt 1. The centering mechanism 2 can push the glass plate 5 to move to the middle before inspection, so as to achieve the purpose of centering, prevent the glass plate 5 from deviating during movement, and facilitate subsequent inspection work;

[0052] The threaded rod 43 is controlled to rotate by the motor 2 42 to adjust the position height of the threaded block 44 and the detection housing 45, so as to facilitate better detection of the glass plate 5. Then, the double-headed motor 46 is started to drive the two reciprocating screws 48 to rotate. The reciprocating screws 48 can drive the two rectangular housings 491 to move away from each other. When the arc plate 496 and the trigger frame 497 contact the inner wall of the detection housing 45 and the stopper 40 respectively, the arc plate 496 will push the movable block 494 to compress the elastic member 495. When the elastic member 495 is compressed to a limited size, the trigger frame 497 will drive the light source assembly 498 to rotate to a vertical direction, so that the imaging device, the combined light source device and the hydraulic oil pumping device are started at the same time to detect the glass plate 5. When the length of the glass plate 5 becomes shorter, the position of the limit plate 493 is adjusted to control the time for the light source assembly 498 to remain vertical, so that the rotation time of the protective housing 32 is also extended backward.

[0053] The starting motor 31 can drive the driving tube 391 and the transport roller 11 to rotate. The rotating transport roller 11 can transport the glass plate 5 that has completed a single test. When the testing mechanism 4 tests the last glass plate 5, the hydraulic pumping device therein will pump hydraulic oil into the hollow tube 393. When the hydraulic oil is pumped into the hollow tube 393, it will flow into the rectangular shell 394, and then push the piston plate 395 in the rectangular shell 394 to move. When the piston plate 395 moves to contact the inner wall of the protective shell 32, the friction between the two can drive the protective shell 32 and the flip roller 33 to rotate.

[0054] When the flip roller 33 and the rubber ring 34 contact the glass plate 5, they will drive it to rotate. The rubber ring 34 can prevent the glass plate 5 from deflecting to prevent it from falling during the flipping process. When the piston plate 395 drives the protective shell 32 to rotate a certain angle, the hydraulic pumping device extracts the hydraulic oil in the hollow tube 393. At this time, the piston plate 395 will not contact the protective shell 32. The protective shell 32 and the glass plate 5 will continue to move downward due to their own gravity. The friction between the inner wall of the arc groove 37 and the surface of the movable rod 38 overcomes the inertia brought by the protective shell 32 and the glass plate 5, ensuring that the protective shell 32 and the flip roller 33 can rotate 180° to complete the flipping work, and then be transported to the transmission belt 1 by the transport roller 11. After centering and detection, the surface defects of the glass plate 5 can be clearly observed.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
