Description

Technical Field

[0001] The invention relates to the technical field of glass production, in particular to a clamp for producing tempered glass. Background Art

[0002] Tempered glass is a specially treated safety glass with high strength and impact resistance. Its manufacturing process mainly involves heating ordinary glass to a temperature close to the softening point (about 650°C), and then rapidly cooling (wind quenching) it to form a balanced structure of compressive and tensile stresses on its surface and inside. This treatment makes the strength of tempered glass 4-5 times higher than that of ordinary glass, and it can withstand greater external impact. In addition, when tempered glass is broken, it forms fine granular fragments rather than sharp fragments, which reduces the risk of injury to the human body, so it is called "safety glass". Tempered glass is widely used in construction, automobiles, home appliances and other fields. In construction, it is often used in curtain walls, doors and windows, partitions and other parts, which are both beautiful and safe; in the automotive industry, it is used for windows and windshields to improve driving safety; in home appliances, such as microwave oven doors and oven panels, it is also common. However, once tempered glass is formed, it cannot be cut or drilled, so all sizes and shapes need to be designed before processing. Overall, tempered glass has become an indispensable material in modern industry and life with its excellent performance and safety.

[0003] In the production process of tempered glass, the cleanliness of the glass surface has a crucial impact on the working effect of the adsorption fixture. The adsorption fixture usually relies on vacuum suction to fix and transfer the glass. If there is dust, stains or other impurities on the glass surface, it will directly affect the adsorption effect of the fixture. First, dust will destroy the seal between the glass and the fixture, resulting in insufficient vacuum suction, causing the glass to slide or fall off during the transmission process, affecting production efficiency and safety. Secondly, dust particles may be embedded in the glass surface under high pressure and high temperature, causing uneven stress in the glass during the tempering process, and even causing cracks or defects, reducing the quality of the finished product.

[0019] like Figure 1 - Fig.10As shown, the present invention provides a technical solution: a clamp for tempered glass production, comprising a handle 1, the end of the handle 1 is fixedly connected to a top cover 2, and the end of the handle 1 away from the top cover 2 is fixedly connected to an anti-rotation mechanism 3. By setting the anti-rotation mechanism 3, when the tempered glass is produced and the tempered glass is moved, the clamp and the tempered glass can be prevented from rotating, so that the tempered glass is tightly connected to the clamp; The lower surface of the top cover 2 is fixedly connected with a venting tube 4, and the bottom of the venting tube 4 is fixedly connected with an exhaust mechanism 5, the exhaust mechanism 5 includes a connecting frame 51, the connecting frame 51 is fixedly connected to the outer surface of the venting tube 4, the bottom end of the connecting frame 51 is fixedly connected with a fixed shell 52, the bottom surface of the inner cavity of the venting tube 4 is fixedly connected with a support rod 53, the end of the support rod 53 is fixedly connected with a stepping motor 54, and the outer surface of the fixed shell 52 is fixedly connected with a large suction cup 6. By setting the exhaust mechanism 5, the air between the large suction cup 6 and the tempered glass can be discharged, so that the large suction cup 6 can be tightly connected to the tempered glass, and the air can be output in the reverse direction at the same time, so that the air can be blown to the tempered glass, and the glass slag and dust on the outer surface of the tempered glass can be blown away. By setting the stepping motor 54, the output end can be rotated after the power is connected and the switch is turned on. By setting the large suction cup 6, it can be tightly adsorbed on the outer surface of the tempered glass. The top surface of the inner cavity of the fixed shell 52 is fixedly connected with a dust removal mechanism 7. By setting the dust removal mechanism 7, when the exhaust mechanism 5 blows air toward the outer surface of the tempered glass, a rotating effect can be generated, and the dust and glass slag on the outer surface of the tempered glass can be cleaned and removed.

[0020] The anti-rotation mechanism 3 includes a connecting rod 31, which is fixedly connected to one end of the handle 1 away from the top cover 2. A small suction cup 32 is fixedly connected to the bottom end of the connecting rod 31. A connecting box 33 passes through the upper surface of the small suction cup 32. A connecting pipe 34 passes through the upper surface of the connecting box 33. A connecting port 35 passes through the end of the connecting pipe 34. The connecting port 35 passes through the upper surface of the large suction cup 6. By setting the small suction cup 32, it can cooperate with the large suction cup 6, so that the device is tightly connected to the tempered glass. By setting the connecting pipe 34, the connecting box 33 and the connecting port 35, the space of the small suction cup 32 and the large suction cup 6 can be connected together, and then when the exhaust mechanism 5 discharges the air in the inner cavity of the large suction cup 6, the air in the inner cavity of the small suction cup 32 can be discharged at the same time, so that the small suction cup 32 is tightly connected to the tempered glass.

[0021] The output end of the stepper motor 54 is provided with a rotating rod 57 through a coupling, and the outer surface of the rotating rod 57 is fixedly connected with a fan blade 58, and the fan blade 58 is located in the inner cavity of the connecting frame 51. By arranging the rotating rod 57 and the fan blade 58, the stepper motor 54 can rotate when it is working, thereby rotating the fan blade 58, and finally generating air flow in the inner cavity of the connecting frame 51. The exhaust mechanism 5 also includes a blocking mechanism 55, and the blocking mechanism 55 includes a connecting pipe 551, and the connecting pipe 551 passes through the air cylinder 4. The inner wall of the connecting pipe 551 is fixedly connected with a blocking ring 552, and the inner wall of the connecting pipe 551 is fixedly connected with a first air permeable plate 553. The surface of the first air permeable plate 553 is fixedly connected with a first spring 554, and the end of the first spring 554 is fixedly connected with a blocking ball 555, and the blocking ball 555 is squeezed and adapted with the inner wall of the blocking ring 552. By setting the blocking ring 552, it can cooperate with the blocking ball 555, and then when the blocking ball 555 contacts the blocking ring 552, the connecting pipe 551 is in a closed state, so that the airflow will not flow. By setting the first spring 554, the upper and lower sides of the blocking ball 555 can be squeezed, and then when there is no pressure, the blocking ball 555 is always connected to the blocking ring 552, and the outer wall of the connecting frame 51 is closed. A one-way valve 56 is passed through the side surface, and the one-way valve 56 includes an exhaust pipe 561. The exhaust pipe 561 passes through the outer side surface of the connecting frame 51. A second air permeable plate 563 is fixedly connected to the inner wall of the exhaust pipe 561. A second spring 564 is fixedly connected to the outer surface of the second air permeable plate 563. By setting the exhaust pipe 561, when the air flow blows into the inner cavity of the large suction cup 6, the air flow can be discharged from the exhaust pipe 561. A blocking block 565 is fixedly connected to the end of the second spring 564. A blocking pad 566 is fixedly connected to the outer surface of the blocking block 565. The blocking pad 566 is frictionally matched with the inner wall of the exhaust pipe 561, and the inner wall of the exhaust pipe 561 is far away. An adsorption cotton 562 is arranged on the side away from the second air permeable plate 563. By setting the blocking block 565, the blocking block 565 and the blocking pad 566 can be separated from the inner wall of the exhaust pipe 561 when the gas is blown, so that the internal air can be discharged smoothly. At the same time, by setting the second spring 564, a pulling force can be applied to the blocking block 565 to ensure that the blocking block 565 is always in close contact with the inner wall of the exhaust pipe 561 when there is no gas blowing, thereby playing a sealing role. In addition, by setting the adsorption cotton 562 in the exhaust pipe 561, dust and glass fragments in the air can be effectively adsorbed to prevent them from entering the interior of the equipment, thereby maintaining the cleanliness and stability of the system.

[0022] The dust removal mechanism 7 includes a limiting ring 71 and a one-way bearing 72. The limiting ring 71 is fixedly connected to the top surface of the inner cavity of the fixed shell 52, and the one-way bearing 72 is fixedly connected to the bottom end of the rotating rod 57. A fixing rod 73 is fixedly connected to the outer ring of the one-way bearing 72. The end of the fixing rod 73 is fixedly connected to a limiting frame 74. The end of the limiting frame 74 is fixedly connected to a rotating ring 75. The rotating ring 75 is located directly above the limiting ring 71. The lower surface of the rotating ring 75 is rotatably connected to a ball 76. The ball 76 is frictionally adapted with the inner cavity of the limiting ring 71. By providing the one-way bearing 72, the fixing rod 73 of the outer ring of the one-way bearing 72 will not rotate when the rotating rod 57 rotates forward, and the fixing rod 73 rotates when the rotating rod 57 reverses. By providing the limiting ring 71, the rotation range of the rotating ring 75 can be controlled. The limit is set to ensure that the rotating ring 75 can achieve smooth and stable rotation on the upper surface of the limiting ring 71. At the same time, by arranging the ball bearings 76 on the limiting ring 71, the friction between the rotating ring 75 and the limiting ring 71 during rotation can be effectively reduced, making the rotation smoother. In addition, a sliding rod 77 is slidably connected in the inner cavity of the limiting frame 74, and a scraper 79 is fixedly installed at the bottom end of the sliding rod 77. The outer surface of the sliding rod 77 is sleeved with a third spring 78, and the bottom end of the third spring 78 is fixed to the upper surface of the limiting frame 74. Through this design, when the rotating ring 75 rotates, the sliding rod 77 and the scraper 79 can move accordingly, so that the scraper 79 keeps in contact with the outer surface of the tempered glass, thereby effectively scraping off dust and impurities on the surface of the tempered glass, ensuring that the contact area between the tempered glass and the large suction cup 6 is always kept clean and tidy.

[0023] Working principle: During use, the operator first connects the stepper motor 54 to the power supply and starts the switch, so that the rotating rod 57 starts to reverse. The reverse rotation of the rotating rod 57 drives the fan blade 58 to rotate, and the airflow generated by the fan blade 58 is from top to bottom. This airflow blows toward the outer surface of the tempered glass, blowing away the floating dust on its surface. At the same time, during the reverse rotation of the rotating rod 57, the fixed rod 73 and the rotating ring 75 will also rotate, thereby driving the scraper 79 to scrape the dust on the outer surface of the tempered glass. This series of actions ensures that there is no dust residue on the surface of the tempered glass when it contacts the large suction cup 6, avoiding the influence of dust on the firmness of adsorption.

[0024] After the dust is removed, the operator controls the stepper motor 54 to rotate forward, so that the rotating rod 57 drives the fan blades 58 to generate an airflow from bottom to top. This airflow extracts the air in the inner cavity of the large suction cup 6 and the small suction cup 32, forming a negative pressure, so that the large suction cup 6 and the small suction cup 32 are tightly adsorbed on the surface of the tempered glass, completing the positioning and clamping of the tempered glass. The whole process ensures the cleanliness and firm clamping of the tempered glass through the purge of the airflow and the adsorption of the suction cup. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should belong to the scope of protection of the present invention. The structures, devices and operating methods that are not specifically described and explained in the present invention are implemented according to conventional means in the field unless otherwise specified and limited.
