Description

Technical Field

[0001] The present invention relates to the technical field of glass detection, and in particular to a tempered glass detection device. Background Art

[0002] Tempered glass is a high-strength glass. After production, it needs to be tested for its compressive properties. The tempered glass testing process generally requires placing the glass on a test bench. A pressure device is then used to apply a certain amount of pressure to both ends of the glass. An auxiliary light source is then evenly illuminated on the glass. A camera is then used to capture an image on the other side of the light source. If the tempered glass shatters or cracks under pressure, the captured image will have a shadow at the location of the shatter or crack, resulting in an uneven light spot. Finally, a computer compares the captured image with a pre-set image to determine if the glass has any defects.

[0003] This type of tempered glass testing equipment typically uses a lifting and lowering mechanism at both ends, with a fixed support structure in the middle. The central support structure is typically a two-roller support roller assembly. During testing, the glass must be inserted into the gap between the upper and lower rollers. Because the glass must be bent downward to a position lower than the central support during testing, both ends of the test bench must be lower than the central fixed support structure. The two sides of the test bench cannot be set higher than or at the same height as the central fixed support structure.

[0004] In actual use, this existing testing equipment has the following shortcomings: 1. There is no glass positioning structure. Therefore, when the downward pressure mechanisms at both ends press down, the vibration of the equipment causes the glass to slide on the middle support platform, which can easily cause the downward pressure mechanism on one side to be unloaded, resulting in unilateral bending of the glass and inability to fully inspect. 2. Glass inspection requires downward pressure from both ends, so the support devices on both sides cannot be higher than the middle support platform. When the glass to be inspected enters the gap between the upper and lower rollers, it needs to be manually aligned with the gap between the upper and lower rollers before insertion. This reduces loading efficiency and makes it difficult to achieve automatic loading and unloading of glass. Summary of the Invention

DETAILED DESCRIPTION

[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] like Figures 1 to 11 As shown, a tempered glass inspection device according to the present invention comprises a top plate 1, a lifting frame 3 and a bottom frame 4; two groups of middle pressure roller assemblies are provided on the lifting frame 3; the middle pressure roller assembly comprises two middle pressure rollers 8 arranged along the height direction; both ends of the middle pressure rollers 8 are rotatably connected to the lifting frame 3; upper fixed support assemblies are provided on both sides of the top plate 1; a flat panel lamp 27 is fixed inside the lifting frame 3; a plurality of cameras 13 are provided on the surface of the top plate 1 facing the lifting frame 3; during the inspection process, the flat panel lamp 27 evenly illuminates the glass to fill in the light for the glass, and the plurality of cameras 13 are responsible for taking pictures of different areas of the glass; the two middle pressure rollers 8 of the same middle pressure roller assembly are arranged up and down, and a gap is formed between the two middle pressure rollers 8 to pass through the glass;

[0035] A lifting assembly is connected between the bottom frame 4 and the lifting frame 3; elastic support roller assemblies are provided on both sides of the lifting frame 3; the elastic support roller assembly includes a rubber roller 5; connecting shafts are fixed at both ends of the rubber roller 5; a lifting seat 26 is rotatably connected to the connecting shaft; the lifting seat 26 is connected to the lifting frame 3 for lifting and sliding; a spring 35 is connected between the lifting frame 3 and the lifting seat 26; a locking assembly is provided on the lifting seat 26 for locking and fixing the rubber roller 5; when the lifting frame 3 descends to the lowest point, the locking assembly releases the grip on the rubber roller 5, allowing the rubber roller 5 to rotate freely on the lifting seat 26; the surface of the rubber roller 5 is covered with a rubber pad;

[0036] When the glass enters the middle pressure roller 8 and the lifting assembly drives the lifting frame 3 to rise relative to the bottom frame 4, the locking assembly immediately locks and fixes the rubber roller 5. At this time, the rubber roller 5 acts as a friction pad. Friction is generated between the rubber roller 5 and the bottom surface of the glass to prevent the glass from sliding on the rubber roller 5 during the rising process, ensuring that the upper fixed support assembly can be accurately aligned with both ends of the glass.

[0037] When the rubber roller 5 is not under pressure, the spring 35 provides support for the lifting seat 26. The top of the rubber roller 5 and the bottom of the glass gap are at the same horizontal plane. When the glass is fed, the lifting frame 3 drops to the lowest point, the locking assembly releases the grip on the rubber roller 5, and the rubber roller 5 can rotate freely. Through the guidance of the rubber roller 5 and the rolling structure formed by the rubber roller 5 and the glass, the glass can be directly inserted. Similarly, when the glass is discharged, the rubber roller 5 can also rotate freely. When the lifting seat 26 is pressed at both ends of the glass, it will be pressed down together with the glass.

[0038] Workflow:

[0039] The first step is to insert the rubber roller 5 at one end of the glass;

[0040] The second step is to push the glass forward. Under the rolling guidance of the rubber roller 5, the front end of the glass passes through the gap formed between the two middle pressure rollers 8 and is placed on the rubber roller 5 on the other side.

[0041] In the third step, the lifting assembly drives the lifting frame 3 to rise, and the middle pressure roller assembly and the glass rise together. At the same time, the locking assembly immediately locks the rubber roller 5, so that the rubber roller 5 forms a large friction force on the glass to prevent the glass from sliding on the rubber roller 5;

[0042] In the fourth step, after the lifting frame 3 rises a certain distance, the upper fixed support assembly begins to contact the upper surface of the glass. As the lifting frame 3 continues to rise, the degree of bending of the glass by the upper fixed support assembly increases until it reaches the set detection position;

[0043] In the fifth step, the flat panel light 27 evenly illuminates the glass to fill in the light. Each camera 13 is responsible for collecting images of different areas of the glass and transmitting the images to the computer for comparison to determine whether there are defects in the glass.

[0044] In the sixth step, after the lifting frame 3 is lowered and reset, the glass is pushed out from the gap formed between the two middle pressing rollers 8.

[0045] As a preferred embodiment of the present invention, the lifting assembly includes a main cylinder 9 and a pulling frame 11; cam seats 6 are slidably connected to both sides of the bottom frame 4; at least one cam surface is provided on the surface of the cam seat 6; the cam surface is composed of an upper supporting plane 602, a lower supporting plane 603 and an inclined plane 601 connected between the upper supporting plane 602 and the lower supporting plane 603; the cam seats 6 are fixed on the pulling frame 11; the two ends of the main cylinder 9 are respectively fixed on the pulling frame 11 and the bottom frame 4; the upper supporting plane 602 is horizontally arranged; rollers 7 are connected to the cam surfaces; the rollers 7 are rotatably connected to the lifting frame 3; the upper supporting plane 602 and the lower supporting plane 603 are both horizontally arranged;

[0046] A slider 20 is fixed on the cam seat 6; a first straight guide rail 25 slidably connected to the slider 20 is fixed on the bottom frame 4;

[0047] The lifting frame 3 utilizes its own gravity to keep the roller 7 in close contact with the cam surface. A first lifting guide sleeve 19 is fixed to the bottom frame 4. A lifting guide shaft 31 is provided on the lifting frame 3 and is slidably connected to the first lifting guide sleeve 19. The cooperation between the first lifting guide sleeve 19 and the lifting guide shaft 31 enables the lifting frame 3 to be raised and lowered and slid in a directional manner on the bottom frame 4.

[0048] After the master cylinder 9 is actuated, the cam seat 6 is pulled along the first straight guide rail 25 via the pull frame 11, causing the roller 7 to move on the cam surface. When the roller 7 rolls to the lower support plane 603, the lifting frame 3 is at its lowest point; when the roller 7 rolls to the upper support plane 602, the lifting frame 3 is at its highest point; when the roller 7 rolls on the inclined surface 601, the lifting frame 3 is in the lifting stage.

[0049] Using a main cylinder 9 power device, each roller 7 forms multiple support points to lift the lifting frame 3, making the overall height of the lifting structure smaller. Multiple support points support evenly at the same time, making the pressure on the bottom frame 4 more uniform;

[0050] The height to which the glass is lifted and the amount it bends are determined by the height difference between the lower support plane 603 and the upper support plane 602, providing a more stable height difference during glass lifting. Even if the master cylinder 9 overtravels the upper support plane 602, the roller 7 remains on the upper support plane 602, ensuring that the glass is lifted to a consistent height each time. This ensures a highly consistent degree of glass bending each time, reduces the precision requirements for the extension and retraction of the master cylinder 9, and simplifies the control circuitry.

[0051] Similarly, the lower support plane 603 is set horizontally to ensure that the top height of the rubber roller 5 is consistent each time the rubber roller 5 is reset to the lowest position to pick up the material, so that the glass is guided by the rubber roller 5 and aligned with the middle pressure roller assembly.

[0052] As a preferred embodiment of the present invention, the locking assembly includes a friction wheel 2, a pressure plate 38, a hinge shaft 24 rotatably connected to the pressure plate 38, and a torsion spring 23 sleeved on the hinge shaft 24; one end of the torsion spring 23 is fixed to the lifting seat 26; the other end of the torsion spring 23 is fixed to the pressure plate 38; a pressure rod 3801 is provided on the pressure plate 38; a through hole 2701 is provided on the frame of the flat lamp 27; a push rod 21 is provided on the bottom frame 4 at a position opposite to the through hole 2701; the friction wheel 2 is fixed to the connecting shaft of the rubber roller 5; the friction wheel 2 is arranged on the swing path of the pressure plate 38; the push rod 21 passes through the through hole 2701 from bottom to top and then extends into the interior of the lifting frame 3;

[0053] The push rod 21 and the pressure rod 3801 are both arranged opposite to the through hole 2701. Under the action of the torsion spring 23, the pressure plate 38 tends to approach the friction wheel 2, thereby realizing the self-locking of the friction wheel 2. The wheel body of the friction wheel 2 is provided with a tooth groove. The side of the pressure plate 38 facing the friction wheel 2 is provided with teeth that are used in conjunction with the above-mentioned tooth groove. The lifting frame 3 is lowered to the lowest point, which is the glass feeding state. The top of the rubber roller 5 is aligned with the glass gap. At this time, the push rod 21 overcomes the elastic force of the torsion spring 23, pushes the pressure rod 3801 to turn the pressure plate 38 outward away from the friction wheel 2, so that the friction wheel 2 and the rubber roller 5 can rotate freely. When the glass is fed, the freely rotating rubber roller 5 can slide into the glass gap.

[0054] When the lifting frame 3 begins to rise, the push rod 21 immediately leaves the pressure rod 3801; the force of the torsion spring 23 causes the pressure plate 38 to press against the friction wheel 2. The teeth of the pressure plate 38 engage with the teeth of the friction wheel 2, locking the rubber roller 5 by the pressure plate 38. The rubber on the surface of the rubber roller 5 forms a static friction force with the surface of the glass. During the lifting process of the lifting frame 3, the glass will not slide relative to the rubber roller 5.

[0055] The rubber roller 5 acts as a pulley structure during loading, making loading more convenient. When the glass is lifted, the rubber rollers 5 at both ends act as anti-slip parts to limit the position of the glass. The glass guide sliding and positioning structure are integrated into one, simplifying the glass loading structure.

[0056] Moreover, the existing lifting motion of the lifting frame 3 is used as the power to drive the pressure plate 38, and there is no need to set up additional power for locking the friction wheel 2. This linkage mode of the lifting frame 3 and the pressure plate 38 has a fast response speed and does not require an additional circuit structure to control the locking of the rubber roller 5.

[0057] As a preferred embodiment of the present invention, the push rod 21 is a screw rod; a first nut 22 is threadedly connected to the screw rod; the first nut 22 is fixed to the bottom frame 4; by rotating the push rod 21 on the first nut 22, the height of the top end of the push rod 21 can be fine-tuned to ensure that the push rod 21 just pushes the pressure plate 38 open when the lifting frame 3 is at the lowest point; and ensure that when the lifting frame 3 starts to rise, the pressure plate 38 is always tightly held on the friction wheel 2 of the rubber roller 5, so that the glass will not move on the rubber roller 5 during the entire rising process, thereby improving the loading accuracy of the glass.

[0058] As a preferred embodiment of the present invention, a lifting sliding shaft 36 is fixed to the lifting seat 26; a third lifting guide sleeve 34 slidably connected to the lifting sliding shaft 36 is fixed to the lifting frame 3; the spring 35 is sleeved on the lifting sliding shaft 36; the two ends of the spring 35 are respectively pressed between the third lifting guide sleeve 34 and the lifting seat 26; the bottom of the lifting sliding shaft 36 is provided with an external thread; a second nut 37 is threadedly connected to the external thread; the second nut 37 is pressed against the bottom of the lifting frame 3; by rotating the second nut 37, the horizontal height of the rubber roller 5 can be adjusted, so that the glass can be aligned with the glass gap before entering the gap.

[0059] As a preferred embodiment of the present invention, the upper fixed support assembly includes an upper roller bracket 12 fixed on the top plate 1; a positive pressure roller 10 is arranged in the upper roller bracket 12; the positive pressure roller 10 is used to form a pressure with the glass surface; no matter before or after the glass is bent, the wheel body of the positive pressure roller 10 can always be tangent to the glass surface, so that the position where the glass is pressed forms a straight line, so that the pressure of the glass in the width direction is balanced.

[0060] As a preferred embodiment of the present invention, both ends of the positive pressure roller 10 are fixed with a fixed shaft 1001; the fixed shaft 1001 is arranged at an eccentric position of the positive pressure roller 10; the fixed shaft 1001 is rotatably connected to the upper roller bracket 12; a turbine 16 is fixed on the fixed shaft 1001; a worm connecting bracket 1201 is provided on the upper roller bracket 12; a worm 15 meshing with the turbine 16 is rotatably connected to the worm connecting bracket 1201; a rotating shaft driving module 18 is fixed on the top plate 1; a rotating shaft 17 is fixed on the worm 15; the rotating shaft 17 is connected to the rotating shaft driving module 18; the rotating shaft driving module 18 consists of a motor and a reduction gearbox; the motor is connected to the input end of the reduction gearbox; the reduction gearbox is a reduction gearbox with two output ends, and the two output ends of the reduction gearbox are respectively fixed on the rotating shaft 17;

[0061] The worm connecting bracket 1201 is a U-shaped frame structure. When the motor starts, it drives the two rotating shafts 17 and two worms 15 to rotate through the reduction gearbox. The worm 15 drives the worm gear 16 to rotate, causing the fixed shaft 1001 to rotate on the upper roller bracket 12. Since the lifting height of the lifting frame 3 is a fixed value, the fixed shaft 1001 and the positive pressure roller 10 are set eccentrically. Therefore, by rotating the positive pressure roller 10, the distance between the bottom of the positive pressure roller 10 and the lifting frame 3 can be adjusted to adjust the required bending amount of the glass. The low transmission ratio between the worm 15 and the worm gear 16 can achieve fine-tuning of the eccentric rotation of the positive pressure roller 10, making the bending amount of the glass more precise. The transmission between the worm 15 and the worm gear 16 has a self-locking effect, preventing the torque from being transmitted to the motor after the positive pressure roller 10 is compressed, which can better protect the motor and prevent the positive pressure roller 10 from rotating arbitrarily, making it more stable and improving the stability of the pressure during glass testing.

[0062] As a preferred embodiment of the present invention, there are two middle pressure roller assemblies; a sliding seat 29 is provided on both sides of the middle pressure roller assembly; a second straight guide rail 28 is fixed to the lifting frame 3; the two ends of the middle pressure roller 8 are rotatably connected to the sliding seats 29 on both sides; the sliding seats 29 are slidably connected to the second straight guide rail 28; the lifting frame 3 is provided with a synchronous motion module for driving the two middle pressure roller assemblies to move on the second straight guide rail 28;

[0063] Since the middle pressure roller 8 is a component that applies lifting force to the glass; the synchronous motion module can drive the middle pressure roller component to move on the lifting frame 3, so that the two middle pressure roller components can move away from or close to each other to adjust the pressure position of the glass; the middle pressure roller 8 is a rotatable roller structure. When the glass is pressed, the synchronous motion module can still drive the middle pressure roller 8 to move horizontally and apply pressure at different positions of the glass. It can not only perform multi-position detection on the glass, but also enable the camera 13 to shoot the originally blocked position after the middle pressure roller 8 moves, so that all positions of the glass can be photographed.

[0064] As a preferred embodiment of the present invention, the synchronous motion module includes a lifting cylinder 32, a third lifting guide sleeve 33 fixed to the bottom of the lifting frame 3, and a lifting shaft 14 slidably connected to the third lifting guide sleeve 33; the two ends of the lifting cylinder 32 are respectively fixed to the lifting shaft 14 and the lifting frame 3; connecting rods 30 are symmetrically provided on both sides of the lifting shaft 14; one end of the two connecting rods 30 is respectively hinged to the sliding seats 29 of the two middle pressure roller assemblies; the other ends of the two connecting rods 30 are both hinged to the lifting shaft 14;

[0065] The lifting cylinder 32 can drive the lifting shaft 14 to perform lifting movement along the third lifting guide sleeve 33, and at the same time drive the two connecting rods 30 to swing, so that the two middle pressure roller assemblies can move synchronously towards each other or synchronously away from each other; through a lifting power structure and a connecting rod setting structure, the synchronous movement of the two middle pressure roller assemblies can be achieved, ensuring the symmetry of the glass pressure and simplifying the power structure.

[0066] The beneficial effects of the present invention are:

[0067] 1. Use the rubber roller to support and guide the glass so that the glass can be accurately inserted into the glass gap. Place the glass directly on the rubber roller and push it into the glass gap manually or by using a fork, which facilitates the feeding and unloading of the glass, improves the feeding and unloading efficiency of the glass, and facilitates the automation of the glass feeding and unloading.

[0068] 2. After the glass and lifting frame begin to rise, the locking assembly immediately locks the rubber roller to prevent the glass from sliding on the rubber roller during the rising process. The corresponding positions at both ends of the glass can be pressed and bent by the upper fixed support assembly to ensure that the glass can complete comprehensive inspection.

[0069] 3. Using a main cylinder power device, each roller forms multiple support points to lift the lifting frame. The overall height of the lifting structure is smaller, and multiple support points support evenly at the same time, making the pressure on the bottom frame more uniform.

[0070] 4. The height to which the glass is lifted and the amount it is bent depend on the height difference between the lower and upper support planes, making the height difference of the glass more stable. When the main cylinder overtravels on the upper support plane, the roller remains on the upper support plane, ensuring that the glass is lifted to a consistent height each time and the degree of glass bending is highly consistent each time. This reduces the main cylinder's requirements for air source stability and simplifies the control circuit. The lower support plane is set horizontally, ensuring that the top height of the rubber roller remains consistent each time it returns to its lowest position to receive the material. The glass is aligned with the middle pressure roller assembly through the rubber roller guide.

[0071] 5. When loading the glass, the rubber roller uses a pulley structure, which allows the glass to be pushed in directly, making loading more convenient. When the glass is lifted, the rubber rollers at both ends serve as anti-slip parts to limit the position of the glass. The glass guide sliding and positioning structures are integrated into one, simplifying the glass loading structure. In addition, the existing lifting power of the lifting frame is used to drive the pressure plate, eliminating the need for additional power for locking the friction wheel. This lifting frame and pressure plate linkage method has a fast response speed and does not require an additional circuit structure to control the locking of the rubber roller.

[0072] 6. By rotating the push rod on the first nut, the height of the top of the push rod can be fine-tuned to ensure that the push rod just pushes the pressure plate open when the lifting frame is at the lowest point; ensuring that the pressure plate is always tightly held on the friction wheel of the rubber roller during the lifting frame's ascent, so that the glass will not move on the rubber roller during the entire ascent process, thereby improving the loading accuracy of the glass.

[0073] 7. Since the lifting height of the lifting frame is a fixed value, and the fixed axis and the positive pressure roller are eccentrically set, the distance between the bottom of the positive pressure roller and the lifting frame can be adjusted by rotating the positive pressure roller to adjust the required bending amount of the glass.

[0074] 8. Through a lifting power structure and a connecting rod setting structure, the synchronous movement of the two middle pressure roller assemblies is achieved, ensuring the symmetry of the glass pressure and simplifying the power structure.

[0075] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
