[0001] The present invention relates to the technical field of glass clamping devices, in particular to an automatic clamping device for large-size optical glass. Background Art

[0002] Large-size optical glass is widely used in many fields such as optical instruments, flat-panel displays, and solar photovoltaics. With the continuous development of related industries, higher requirements are placed on the processing and manufacturing of large-size optical glass. Among them, automatic clamping technology is a key link in the optical glass production process.

[0003] However, in the existing technology, large-sized optical glass is heavy, and the existing mechanical clamping device is prone to deformation and vibration when clamping large-sized and heavy optical glass during high-speed movement or long-stroke transportation, which affects the clamping accuracy and stability. In addition, the end effector cannot adapt well to the special surface requirements of optical glass, and is prone to scratches or poor adsorption. Summary of the Invention

[0006] Preferably, guide rods are provided on both sides of the positive and negative thread ball screws, the guide rods are fixedly connected to the inner wall of the support frame, and the sliders are movably connected to the outer wall of the guide rods. The positive and negative thread ball screws drive the sliders on both sides to move synchronously in opposite directions through left and right rotating threads, ensuring that the two sets of suction cup mechanisms are equidistantly adjusted with the center of the support frame as the symmetrical point, avoiding the problem of unbalanced loading caused by unilateral force, and ensuring that the adsorption force is evenly distributed.

[0007] Preferably, a through hole is opened through the middle outer wall of the support frame, and a synchronous pulley mechanism is movably connected inside the through hole. The output shaft end of the servo motor and the middle outer wall of the positive and negative ball screw are connected through a synchronous pulley mechanism. The synchronous pulley adopts toothed meshing transmission to eliminate the slippage of the traditional belt, ensure that the angular accuracy of the servo motor is transmitted to the screw at a 1:1 ratio, and avoid the suction cup positioning deviation caused by the transmission gap.

[0008] Preferably, the suction cup mechanism includes a third cylinder, a pneumatic joint and a vacuum suction cup. The bottom end of the telescopic rod of the third cylinder is fixedly connected to the pneumatic joint, and the vacuum suction cup is fixedly connected to the bottom surface of the pneumatic joint.

[0010] Preferably, the top surface of the top plate is fixedly connected to a limit plate, and a connecting groove is opened through the center of the top surface of the top plate. The connecting groove has a diameter of 50 mm and can integrate vacuum pipes, air pipes, cables, etc. to avoid the risk of entanglement caused by exposed pipelines, while keeping the appearance of the device neat.

[0011] Preferably, the bottom surface of the top plate is fixedly connected to a fixed connecting plate, and both ends of the connecting shaft are fixedly connected to the outer wall of the fixed connecting plate.

[0012] Preferably, the lifting mechanism includes cylinder 2, a connecting plate and an installation base plate. Cylinder 2 is fixedly installed at the center of the bottom surface of the top plate.

Combined with the reinforcement structure of the connecting plate, the shaking amplitude during the lifting process is controlled within ±0.3mm to avoid adsorption failure of the suction cup due to vertical vibration.

[0013] Preferably, the bottom surface of the connecting plate is fixedly connected to the center of the top surface of the mounting base plate, and the mounting block is fixedly connected to the outer wall of the mounting base plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the surface and edge of the glass are restrained simultaneously by a composite clamping structure of vacuum suction cups + silicone side clamps, which significantly reduces deformation and vibration during high-speed movement or long-stroke transportation, improves clamping accuracy, and avoids the risk of falling off due to single adsorption or clamping. The adjustment mechanism uses a servo motor and a positive and negative ball screw to achieve stepless adjustment of the suction cup spacing, and is compatible with large-size glass of different lengths and widths.

[0015] 2. In the present invention, the cylinder three of the suction cup mechanism can independently control the downward stroke of the suction cup to adapt to the slight fluctuations on the glass surface, ensuring that the vacuum suction cup is completely fitted to the glass. The combination of the guide rod and the positive and negative threaded ball screw achieves high displacement accuracy, ensuring that the suction cup is accurately aligned with the glass adsorption position, avoiding loose adsorption due to position deviation.

[0016] 3. In the present invention, the vacuum suction cup is made of flexible material and cooperates with the adaptive downward pressure of cylinder three to avoid surface scratches caused by hard contact; the anti-slip groove of the silicone chuck evenly distributes the clamping force through elastic deformation to prevent damage to the glass edge and meet the high surface precision requirements of optical glass.

[0017] 4. In the present invention, anti-slip grooves are provided on the surface of the silicone chuck to increase the friction with the edge of the glass. At the same time, the elastic deformation of the silicone material can buffer the clamping force and avoid edge damage or scratches caused by rigid contact. The adjusting bolt passes through the clamp arm to achieve up and down adjustment and fix the position of the adjustment plate, change the clamping height of the silicone chuck, and adapt to glass of different thicknesses. The support rod connects the silicone chucks on both sides to enhance the rigidity of the clamping structure and prevent uneven clamping force caused by deformation of the clamp arm.

Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] Example 1: Reference Figure 1 - Figure 7 As shown: An automatic clamping device for large-size optical glass, including a top connecting seat 1, side clamping mechanisms 2 are installed on the bottom surfaces of both ends of the top connecting seat 1, a lifting mechanism 3 is installed at the center of the bottom surface of the top connecting seat 1, and an adjusting mechanism 4 is installed on the bottom surface of the lifting mechanism 3. The adjusting mechanism 4 is provided with two groups, and three groups of suction cup mechanisms 5 are provided on one side of the two groups of adjusting mechanisms 4, one of which is fixedly installed on the bottom surface of the lifting mechanism 3. The adjusting mechanism 4 includes a support frame 41, a mounting block 42, a servo motor 43, a traction block 44, a synchronous pulley mechanism 45 and a side mounting plate 46. One side of the mounting block 42 is fixedly connected to the outer wall of the support frame 41, the bottom surface of the mounting block 42 is fixedly connected to the lifting mechanism 3, one end of the side mounting plate 46 is fixedly connected to the outer wall of the support frame 41, the servo motor 43 is fixedly connected to the outer wall of the side mounting plate 46, and the inner wall of the support frame 41 is rotatably connected with a positive and negative tooth ball screw 412, and the outer wall screw of the positive and negative tooth ball screw 412 The sliding block 413 is sleeved with a thread, and one end of the traction block 44 is fixedly connected to the outer wall of the sliding block 413. The servo motor 43 drives the positive and negative tooth ball screw 412 to rotate through the synchronous pulley mechanism 45, thereby controlling the sliding block 413 to drive the traction block 44 to move. The suction cup mechanism 5 is fixedly installed at the end of the traction block 44. The top connecting seat 1 includes a top plate 11, and the bottom surface of the top plate 11 is fixedly connected to the side support plate 12. The top surface of the clamping arm 21 is penetrated by a movable groove 13. The side clamping mechanism 2 includes a clamping arm 21, a connecting shaft 22, an adjusting plate 23 and a silicone clamp 24. The top of the clamping arm 21 is fixedly sleeved on the outer wall of the connecting shaft 22, and the adjusting plate 23 is installed on the lower inner wall of the clamping arm 21. The silicone clamp 24 is fixedly connected to the bottom end of the adjusting plate 23. The bottom surface of the side support plate 12 is fixedly connected to the fixing frame 16. The inner wall of the fixing frame 16 is rotatably connected to the cylinder 17. One end of the telescopic rod of the cylinder 17 is rotatably connected to the top of the clamping arm 21.

[0022] In this embodiment, when clamping large-size optical glass, the lifting mechanism 3 controls the adjustment mechanism 4 and the suction cup mechanism 5 to move downward so that the bottom end of the suction cup mechanism 5 moves above the optical glass, and the auxiliary servo motor 43 drives the positive and negative ball screws 412 to rotate and control the traction blocks 44 at both ends of the support frame 41 to move synchronously to the middle or to both ends, thereby adjusting the spacing between the suction cup mechanisms 5 at both ends so that the six groups of suction cup mechanisms 5 can accurately cover the adsorption positions of the optical glass and adapt to glasses of different sizes and shapes. Then, the suction cup mechanism 5 is automatically pressed down and vacuum adsorbed on the surface of the optical glass to achieve stable adsorption and fixation. Then, the suction cup mechanism 5 is lifted by the lifting mechanism 3 chassis and the cylinder 17 is used to assist in controlling the clamping arm 21 to rotate on both sides of the top connecting seat 1. The silicone clamp 24 is used to assist in clamping and fixing the edge of the glass. The vacuum suction cup 53 provides the main adsorption force, and the side clamping mechanism 2 assists in constraining the edge, reducing vibration and deformation during high-speed movement or long-stroke transportation, and improving the clamping accuracy.

[0023] Example 2: According to Figure 4-Figure 7 As shown, guide rods 411 are provided on both sides of the positive and negative ball screws 412, the guide rods 411 are fixedly connected to the inner wall of the support frame 41, the slider 413 is movably connected to the outer wall of the guide rods 411, a through hole 414 is penetrated through the middle outer wall of the support frame 41, a synchronous pulley mechanism 45 is movably connected inside the through hole 414, the output shaft end of the servo motor 43 and the middle outer wall of the positive and negative ball screws 412 are connected through the synchronous pulley mechanism 45, the suction cup mechanism 5 includes a cylinder three 51, an air control joint 52 and a vacuum suction cup 53, the bottom end of the telescopic rod of the cylinder three 51 is fixedly connected to the air control joint 52, and the vacuum suction cup 53 is fixedly connected to the bottom surface of the air control joint 52.

[0024] In this embodiment, the guide rod 411 is arranged in parallel with the positive and negative ball screw 412. When the screw rotates, the sliders 413 on both sides slide in opposite directions along the guide rod 411 to ensure that the traction block 44 moves synchronously and smoothly. The synchronous pulley mechanism 45 transmits the power of the servo motor 43 and connects the screw through the through hole 414 to achieve gapless transmission, avoiding the return error of traditional gear transmission. The cylinder three 51 of the suction cup mechanism 5 can independently control the downward stroke of the suction cup to adapt to the slight fluctuations on the glass surface and ensure that the vacuum suction cup 53 is completely fitted with the glass. The combination of the guide rod 411 and the positive and negative ball screw 412 achieves high displacement accuracy, ensuring that the suction cup is accurately aligned with the glass adsorption position to avoid loose adsorption due to position deviation. The synchronous pulley mechanism 45 reduces transmission noise and vibration, cooperates with the guide rod 411 for guidance, improves the smoothness of the adjustment process, and is suitable for clamping high-precision optical glass.

[0025] Example 3: According to Figure 1 - Figure 4As shown, the side clamping mechanism 2 also includes a support rod 25, an anti-slip groove 26 and an adjusting bolt 27. The support rod 25 is fixedly connected between the outer walls of the two silicone clamps 24. The anti-slip groove 26 is opened on the outer wall of the silicone clamp 24. The adjusting bolt 27 is threaded through and connected to the lower outer wall of the clamping arm 21. The top surface of the top plate 11 is fixedly connected to the limiting plate 14. A connecting groove 18 is opened through the center of the top surface of the top plate 11. The bottom surface of the top plate 11 is fixedly connected to the fixed connecting plate 15. The two ends of the connecting shaft 22 are fixedly connected to the outer wall of the fixed connecting plate 15. The lifting mechanism 3 includes a cylinder 2 31, a connecting plate 32 and a mounting base plate 33. The cylinder 2 31 is fixedly installed at the center of the bottom surface of the top plate 11. The bottom end of the telescopic rod of the cylinder 2 31 is fixedly connected to the top surface of the connecting plate 32. The bottom surface of the connecting plate 32 is fixedly connected to the center of the top surface of the mounting base plate 33. The mounting block 42 is fixedly connected to the outer wall of the mounting base plate 33.

[0026] In this embodiment, an anti-skid groove 26 is provided on the surface of the silicone chuck 24 to increase the friction with the edge of the glass. At the same time, the elastic deformation of the silicone material can buffer the clamping force to avoid edge damage or scratches caused by rigid contact. The adjusting bolt 27 passes through the clamping arm 21 to achieve up and down adjustment and fix the position of the adjusting plate 23, change the clamping height of the silicone chuck 24, and adapt to glass of different thicknesses. The support rod 25 connects the silicone chucks 24 on both sides to enhance the rigidity of the clamping structure and prevent uneven clamping force caused by deformation of the clamping arm 21. The silicone material and the anti-skid groove 26 design solve the problem that traditional metal chucks are prone to scratching the glass surface. At the same time, the anti-skid groove 26 increases the friction coefficient to prevent the glass from sliding during the clamping process. The chuck position can be quickly adjusted by adjusting the bolt 27 without replacing hardware, thereby improving the versatility of the device for glass of different specifications and reducing the cost of replacement.

[0027] The method of use and working principle of this device are as follows: the lifting mechanism 3 controls the adjustment mechanism 4 and the suction cup mechanism 5 to move downward so that the bottom end of the suction cup mechanism 5 moves above the optical glass, and the auxiliary servo motor 43 drives the positive and negative tooth ball screw 412 to rotate and control the traction blocks 44 at both ends of the support frame 41 to move synchronously to the middle or to both ends, thereby adjusting the distance between the suction cup mechanisms 5 at both ends, and then the suction cup mechanism 5 is pressed down autonomously and vacuum adsorbed on the surface of the optical glass, and then the suction cup mechanism 5 is lifted by the lifting mechanism 3 chassis and the cylinder 17 is used to assist in controlling the clamping arm 21 to rotate on both sides of the top connecting seat 1, The glass edge is assisted to be clamped and fixed by the silicone chuck 24, and the main adsorption force is provided by the vacuum suction cup 53. The side clamping mechanism 2 assists in restraining the edge. After the clamping is completed, the lifting mechanism 3 lifts the device and the glass is transported by the external mechanical arm. When releasing, the vacuum adsorption is first disconnected, and then the side clamp is released by the cylinder 17 to complete the unloading. The guide rod 411 is arranged in parallel with the positive and negative ball screw 412. When the screw rotates, the sliders 413 on both sides slide in opposite directions along the guide rod 411. The synchronous pulley mechanism 45 transmits the power of the servo motor 43 and connects the screw through the through hole 414 to achieve gapless transmission. To avoid the return error of traditional gear transmission, the cylinder 3 51 of the suction cup mechanism 5 can independently control the downward stroke of the suction cup to adapt to the slight fluctuations on the glass surface, ensuring that the vacuum suction cup 53 is completely fitted with the glass. The combination of the guide rod 411 and the positive and negative tooth ball screw 412 achieves high displacement accuracy, ensuring that the suction cup is accurately aligned with the glass adsorption position. The synchronous pulley mechanism 45 reduces transmission noise and vibration, and cooperates with the guide rod 411 to guide and improve the stability of the adjustment process. It is suitable for clamping high-precision optical glass. The surface of the silicone chuck 24 is provided with an anti-slip groove 26 to increase the friction with the edge of the glass. At the same time, the silicone material is elastic. Flexible deformation can buffer the clamping force and avoid edge damage or scratches caused by rigid contact. The adjusting bolt 27 runs through the clamp arm 21 to achieve up and down adjustment and fix the position of the adjusting plate 23, change the clamping height of the silicone clamp 24, and adapt to glass of different thicknesses. The support rod 25 connects the silicone clamps 24 on both sides to enhance the rigidity of the clamping structure and prevent uneven clamping force caused by deformation of the clamp arm 21. The silicone material and anti-slip groove 26 design solve the problem that traditional metal clamps easily scratch the glass surface. At the same time, the anti-slip groove 26 increases the friction coefficient. The clamp position can be quickly adjusted by adjusting the bolt 27 without replacing hardware.
