Description

Technical Field

[0001] This utility model belongs to the field of rotating device technology, and specifically relates to a glass rotating device. Background Technology

[0002] A glass rotation device is an auxiliary equipment used in the processing, inspection, or display of glass products. It is commonly used for clamping, positioning, and rotating glass workpieces. Its main applications include glass polishing, grinding, etching, coating, and inspection, and it is particularly suitable for processing the sides or full-angle surfaces of circular or near-circular glass sheets. A typical glass rotation device usually includes a turntable structure for supporting and rotating the glass, clamping assemblies for vertical clamping, and sometimes control and drive mechanisms.

[0003] Most glass rotation devices on the market are driven by manual or single-direction motors. The centering and positioning of the glass relies heavily on manual judgment and experience, which can easily cause center offset and affect processing accuracy. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a glass rotation device. This device can quickly and accurately position and firmly clamp the glass plate, possessing strong practicality, stability, and safety. It can be widely applied to various industrial or experimental occasions such as glass processing, testing, display, and treatment, and has excellent prospects for promotion and application.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a glass rotating device, comprising a base, a bearing ring on the top of the base, a turntable rotatably mounted on the inner side of the bearing ring, a lower clamping seat mounted on the top of the turntable, a support column mounted on the top of the base, a cylinder mounted on the top of the support column, a lifting arm mounted on the top of the cylinder, a fixed shaft mounted at the bottom of one end of the lifting arm, an upper clamping seat rotatably mounted at the bottom of the fixed shaft, four guide grooves on the top of the turntable, a slider slidably mounted inside the guide grooves, a lead screw rotatably mounted inside the guide grooves, one end of the lead screw being connected to a first bevel gear, a motor mounted on the inner side of the turntable, the output end of the motor being connected to a second bevel gear, the second bevel gear meshing with the first bevel gear, a transmission connection between the slider and the lead screw, and a glass side clamping device on the top of the slider.

[0006] The beneficial effects of this invention are as follows: The operator places a circular glass plate flat on the lower clamping seat, then controls the electric telescopic rod to drive the clamping block to rise. The motor drives the second bevel gear to rotate, and the meshing transmission between the second and first bevel gears drives the lead screw to rotate. The lead screw and the slider are connected by a threaded structure, allowing the slider to move synchronously towards the side of the glass in the guide groove. This, in turn, causes the clamping block to move closer to the glass. Through the contact between the clamping block and the glass, the glass is slowly shifted towards the center of the turntable until it is centered, so that the center of the glass coincides with the axis of the lower clamping seat. This achieves automated and precise positioning, avoids human error, and improves clamping uniformity.

[0007] After clamping the glass plate, the air pump can be started to extract air through the connected suction pipe, forming a continuous negative pressure suction force at the negative pressure suction hole where the top of the pump contacts the bottom of the glass. This enhances the adhesion of the bottom surface of the glass, improves rotational stability, and prevents displacement caused by centrifugal force at high speeds.

[0008] As a further improvement to the above technical solution: a motor is installed inside the base, and the output end of the motor is fixedly connected to the turntable.

[0009] The motor is used to drive the turntable to rotate.

[0010] To improve clamping stability:

[0011] As a further improvement to the above technical solution: the bottom of the upper clamping seat and the top of the lower clamping seat are provided with anti-slip rubber pads.

[0012] The beneficial effects of this improvement are: by setting anti-slip rubber pads, the friction between the bottom of the upper clamping seat and the top of the lower clamping seat and the glass can be increased, thereby improving clamping stability.

[0013] To clamp the sides of the glass plate:

[0014] As a further improvement to the above technical solution: the glass side clamping device includes a support frame fixed to the top of the slider, an electric telescopic rod is installed on the inner side of the support frame, the piston rod end of the electric telescopic rod is connected to the clamping block, and the clamping block passes through the top plate of the support frame and is slidably connected to it.

[0015] The beneficial effects of this improvement are as follows: when it is necessary to position the glass, the electric telescopic rod is controlled to drive the clamping block to rise so that it can contact the side of the glass. When the positioning is completed, the electric telescopic rod is controlled to drive the clamping block to fall to avoid collision with the polishing equipment used to polish the side of the glass.

[0016] For the control of this device:

[0017] As a further improvement to the above technical solution: a control device is provided on the side of the base.

[0018] The beneficial effects of this improvement are as follows: the control device is equipped with operation buttons and a display screen, and the control device is equipped with a PLC controller for the operation of the device and the running of the control program.

[0019] To improve the clamping stability of the glass:

[0020] As a further improvement to the above technical solution: an air pump is installed on the side of the turntable, the air pump is connected to one end of the air extraction pipe, the air extraction pipe is fixedly installed inside the turntable, and the top end of the air extraction pipe is connected to the negative pressure suction hole.

[0021] The beneficial effects of this improvement are as follows: after the air pump is started, air is drawn out through the air extraction pipe connected to it, and a continuous negative pressure adsorption force is formed at the negative pressure suction hole at its top that contacts the bottom of the glass, which enhances the adhesion of the bottom surface of the glass, improves rotational stability and prevents displacement caused by centrifugal force at high speeds.

[0022] As a further improvement to the above technical solution: a conductive ring is installed on the top of the base, and a spring contact is installed on the bottom of the turntable.

[0023] The conductive ring installed on the top of the base maintains contact with the spring plate contacts installed on the bottom of the turntable, enabling continuous transmission of electrical signals during rotation and providing uninterrupted power supply to electrical components such as motors, electric telescopic rods, and air pumps located on the rotating structure.

[0024] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0032] like Figure 1-5 As shown, a glass rotating device includes a base 1, a bearing ring 2 on the top of the base 1, a turntable 3 rotatably mounted on the inner side of the bearing ring 2, a lower clamping seat 5 on the top of the turntable 3, a support column 6 on the top of the base 1, a cylinder 7 on the top of the support column 6, a lifting arm 8 on the top of the cylinder 7, a fixed shaft 9 on the bottom of one end of the lifting arm 8, an upper clamping seat 10 rotatably mounted on the bottom of the fixed shaft 9, four guide grooves 11 on the top of the turntable 3, a slider 12 slidably mounted inside the guide grooves 11, a lead screw 13 rotatably mounted inside the guide grooves 11, one end of the lead screw 13 connected to a first bevel gear 14, a motor 15 mounted inside the turntable 3, the output end of the motor 15 connected to a second bevel gear 16, the second bevel gear 16 meshing with the first bevel gear 14, a transmission connection between the slider 12 and the lead screw 13, and a glass side clamping device 17 on the top of the slider 12.

[0033] The operator places the circular glass plate flat on the lower clamping seat 5, then controls the electric telescopic rod 24 to drive the clamping block 25 to rise. The motor 15 drives the second bevel gear 16 to rotate, and the meshing transmission between the second bevel gear 16 and the first bevel gear 14 drives the lead screw 13 to rotate. The lead screw and the slider 12 are connected by a threaded structure, which allows the slider to move synchronously towards the side of the glass in the guide groove 11. This, in turn, moves the clamping block 25 closer to the glass. Through the contact between the clamping block 25 and the glass, the glass is pushed slowly towards the center of the turntable until it is centered, so that the center of the glass coincides with the axis of the lower clamping seat 5. This achieves automated and precise positioning, avoids human error, and improves the uniformity of clamping.

[0034] After clamping the glass plate, the air pump 19 can be started to extract air through the air extraction pipe 20 connected to it, forming a continuous negative pressure suction force at the negative pressure suction hole 21 at its top that contacts the bottom of the glass, which enhances the adhesion of the bottom surface of the glass, improves rotational stability and prevents displacement caused by centrifugal force at high speeds.

[0035] The base 1 is equipped with a motor 4, and the output end of the motor 4 is fixedly connected to the turntable 3.

[0036] Motor 4 is used to drive the turntable 3 to rotate.

[0037] The bottom of the upper clamping seat 10 and the top of the lower clamping seat 5 are provided with anti-slip rubber pads 18.

[0038] By setting the anti-slip rubber pad 18, the friction between the bottom of the upper clamping seat and the top of the lower clamping seat 5 and the glass can be increased, thereby improving clamping stability.

[0039] The glass side clamping device 17 includes a support frame 23 fixed to the top of the slider 12. An electric telescopic rod 24 is installed on the inner side of the support frame 23. The piston rod end of the electric telescopic rod 24 is connected to the clamping block 25. The clamping block 25 passes through the top plate of the support frame 23 and is slidably connected to it.

[0040] When the glass needs to be positioned, the electric telescopic rod 24 is controlled to drive the clamping block 25 to rise so that it can contact the side of the glass. When the positioning is completed, the electric telescopic rod 24 is controlled to drive the clamping block 25 to fall to avoid collision with the polishing equipment used to polish the side of the glass.

[0041] The base 1 is provided with a control device 22 on its side.

[0042] The control device 22 is equipped with operation buttons and a display screen. The control device 22 has a PLC controller inside, which is used for the operation of the device and the running of the control program.

[0043] An air pump 19 is installed on the side of the turntable 3. The air pump 19 is connected to one end of the air extraction pipe 20. The air extraction pipe 20 is fixedly installed inside the turntable 3. The top end of the air extraction pipe 20 is connected to the negative pressure suction hole 21.

[0044] After the air pump 19 is started, it draws out air through the air extraction pipe 20 connected to it, and forms a continuous negative pressure adsorption force at the negative pressure suction hole 21 at its top that contacts the bottom of the glass, which enhances the adhesion of the bottom surface of the glass, improves rotational stability and prevents displacement caused by centrifugal force at high speed.

[0045] A conductive ring 26 is installed on the top of the base 1, and a spring contact 27 is installed on the bottom of the turntable 3.

[0046] The conductive ring 26 installed on the top of the base 1 is in contact with the spring plate contact 27 installed on the bottom of the turntable 3, so as to realize the continuous transmission of electrical signals during rotation and provide uninterrupted power supply to electrical components such as motor 15, electric telescopic rod 24, and air pump 19 located on the rotating structure.

[0047] The working principle and usage process of this utility model are as follows: During use, the operator first starts the entire system using the operation buttons on the control device 22, ensuring that the motor 4 inside the base 1, the motor 15 inside the turntable 3, the cylinder 7 at the top of the support column 6, the slider 12 in the guide groove 11 and its top-mounted glass side clamping device 17, as well as the support frame 23, electric telescopic rod 24, and clamping block 25 located on the slider 12 are all in their initial standby state. Then, the operator places the circular glass plate flat on the lower clamping seat 5, and then controls the electric telescopic rod 24 to drive the clamping block 25 to rise. The motor 15 drives the second bevel gear 16 to rotate, and through the meshing transmission between the second bevel gear 16 and the first bevel gear 14, it drives the lead screw 13 to rotate. The lead screw and... The sliders 12 are driven by a threaded structure, allowing them to move synchronously towards the side of the glass in the guide groove 11. This, in turn, moves the clamping block 25 closer to the glass. The contact between the clamping block 25 and the glass pushes the glass slowly towards the center of the turntable until it is centered, aligning the center of the glass with the axis of the lower clamping seat 5. This achieves automated and precise positioning, avoiding human error and improving clamping uniformity. After the glass is positioned, the motor 15 can be controlled to drive the sliders 12 and the glass side clamping device 17 to reset. The electric telescopic rod 24 can be controlled to lower the clamping block 25 to avoid collision with the polishing equipment used for polishing the glass side. At the same time, the cylinder 7 can be controlled to drive the lifting arm 8 connected to it to move downward. The fixed shaft 9 connected to the bottom of the lifting arm 8 drives the upper clamp at the lower end. The holder 10 slowly descends, causing the upper holder 10 and lower holder 5 to clamp the upper and lower surfaces of the glass respectively, forming a reliable and stable vertical clamping structure. This effectively prevents the glass from tilting or sliding during rotation. The anti-slip pads 18 increase the friction between the bottom of the upper holder and the top of the lower holder 5 and the glass, improving clamping stability. Simultaneously, the air pump 19 installed on the side of the turntable 3 starts, drawing air out through the connected suction pipe 20. This creates a continuous negative pressure suction force at the negative pressure suction hole 21 at its top, which contacts the bottom of the glass. This enhances the adhesion of the glass's bottom surface, improves rotational stability, and prevents displacement due to centrifugal force at high speeds. Subsequently, the motor 4 starts, its output end fixedly connected to the turntable 3, driving the entire turntable slowly and evenly. The rapid rotation allows the glass to rotate 360 ​​degrees around its center, suitable for multi-angle inspection and side polishing. Furthermore, the conductive ring 26 mounted on the top of the base 1 maintains contact with the spring contact 27 mounted on the bottom of the turntable 3, ensuring continuous transmission of electrical signals during rotation. This provides uninterrupted power to electrical components such as the motor 15, electric telescopic rod 24, and air pump 19 located on the rotating structure, ensuring coordinated, efficient, and continuous operation of all actions. In summary, this device can quickly and accurately position and firmly clamp glass plates, possessing strong practicality, stability, and safety. It is widely applicable to various industrial or experimental applications such as glass processing, testing, display, and treatment, and has excellent prospects for widespread application.
