Description

Technical Field

[0001] The present invention relates to the technical field of tempered glass testing, and more particularly to a tempered glass impact testing device. Background Art

[0002] Tempered glass is a type of safety glass. In fact, tempered glass is a prestressed glass. In order to increase the strength of the glass, chemical or physical methods are usually used to form compressive stress on the glass surface. When the glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and enhancing the glass's own resistance to wind pressure, cold and heat, impact, etc. The tempered glass impact tester is a professional equipment used to evaluate the impact resistance of tempered glass. It tests the strength, breakage resistance and safety performance of the glass by simulating external force impact.

[0003] However, existing tempered glass impact testing devices are overly simple in structure and have single functions. It is not convenient to clean the broken tempered glass during use. If it is not cleaned in time, it will affect the subsequent tempered glass testing. Moreover, most of the cleaning is done manually, which is not only inefficient, but also forms a large number of sharp particles after the tempered glass is broken. Even if gloves are worn, the sharp particles will pierce the gloves and scratch the fingers.

[0028] See also Figure 6 A rubber pad 33 is provided on the opposite side of the fixing plate 1 9 and the fixing plate 2 12. The rubber pad 33 can protect the glass and prevent the glass from being broken when the fixing plate 1 9 and the fixing plate 2 12 clamp the glass.

[0029] Working principle: When the present invention is in use, the tempered glass can be placed on the rotating shaft 5 by a mechanical arm or manually, and then the motor 27 can be started. The output shaft of the motor 27 drives one of the sprockets 4 to rotate, and the remaining sprockets 4 are driven to rotate synchronously under the action of the chain 41. The sprocket 4 fixedly connected to the output shaft of the motor 27 will drive the connecting shaft 6 to rotate synchronously when rotating, thereby driving the sprocket 4 set in the other installation groove 3 and the rotating shaft 5 to rotate, and then the tempered glass is transported.

[0030] When the tempered glass passes the sensor 26, the sensor 26 will send a signal to the controller 25, which will stop the motor 1 27 through the controller 25, thereby stopping the transportation of the tempered glass. At this time, the tempered glass is located directly above the fixing plate 1 9 and directly below the fixing plate 2 12. Then the controller 25 will start the cylinder 8, the motor 3 29 and the electromagnet 21. After the cylinder 8 is started, the telescopic end of the cylinder 8 will push the fixing plate 1 9 to move upward, thereby pushing the tempered glass to move upward and away from the rotating shaft 5, and then clamping the tempered glass between the fixing plate 1 9 and the fixing plate 2 12. At this time, the glass will be between the two fixing plates 3 36.

[0031] After the motor three 29 is started, it will drive the winding roller 23 to reel or unwind the wire rope 24. When the wire rope 24 is unwinding, the connecting block 20 will move downward along the mounting rod 15 according to its own gravity, so that the electromagnet 21 provided at the bottom of the connecting block 20 contacts the iron block 19, thereby adsorbing the iron block 19, so that the impact head 17 and the connecting block 20 are fixed together. Then, the motor three 29 and the winding roller 23 are used again to rewind the wire rope 24, so that the connecting block 20 and the impact head 17 can move upward along the mounting rod 15, so that the impact head 17 rises to a certain height. Finally, the power supply of the electromagnet 21 is disconnected, so that the electromagnet 21 continues to adsorb the iron block 19. At this time, the impact head 17 will move downward along the mounting rod 15, thereby impacting the tempered glass.

[0032] After the impact is completed, the high-speed camera 30 will test whether the glass is broken. If the glass is not broken, the high-speed camera 30 will transmit a signal to the controller 25. The controller 25 will start the cylinder 8 and the motor 1 27 again to move the tempered glass downward and onto the rotating shaft 5. After the motor 1 27 is started, the qualified tempered glass will be transported. At the same time, the next tempered glass to be tested will replace the position of the previous tempered glass, so as to be tested again. If the tempered glass is broken, there are two situations for the tempered glass at this time. One is that the glass is completely broken and forms fragments of different sizes. After that, the fragments will fall directly onto the conveyor belt 14. Then the high-definition camera 30 will According to the broken situation of the glass, the motor 28 is started through the controller 25. The output shaft of the motor 28 will drive the rotating roller 13 to rotate, thereby driving the conveyor belt 14 to rotate continuously, and then the broken glass on the conveyor belt 14 is transported to one end of the conveyor belt 14 so that the tester can clean the broken glass. Another situation is that the glass is broken, but the overall frame is still maintained, only mesh cracks appear. At this time, the high-definition camera 30 will start the electric push rod 34 through the controller 25. The telescopic end of the electric push rod 34 will push the push plate 35 close to the glass, thereby pushing the glass into the two fixed plates 3 36. Finally, the staff can remove the broken glass from one end of the fixed plate 36.
