[0031] In summary, the present invention has the following beneficial technical effects:

[0032] 1. The present invention is provided with components such as a negative pressure regulating structure, an air transmission structure, and a suction cup structure. The negative pressure structure applies suction to the suction cup structure through the air transmission structure, so that the suction cup structure applies suction to the glass plate it contacts. The negative pressure regulating structure adjusts the suction of the suction cup structure to prevent the glass plate from being broken due to excessive suction of the suction cup structure.

[0033] 2. The present invention provides a track frame, an inner through-shaft, a horizontal elastic telescopic rod, a blocking ball and other components. After the through-hole suction cup adsorbs the glass plate, the suspension connecting frame moves upward and pulls the glass plate adsorbed by the through-hole suction cup upward through the elastic connection between the collar and the vertical pole. Under gravity, the glass plate pulls the collar relatively elastically close to the upper end of the vertical pole through the vertical pole. At the same time, the mounting ring drives the inner through-shaft to move downward relative to the track frame through the end belt and the pressure relief elbow, driving the outer plate to gradually move away from the pressure relief elbow, thereby increasing the blocking ball and the pressure relief elbow. The distance from the large diameter end makes the weight of the glass plate adsorbed by the through-hole suction cup greater, and the distance between the outer plate and the pressure relief elbow becomes larger, and the suction force generated in the lower tube drives the blocking ball to move toward the large diameter end of the pressure relief elbow. When the blocking ball moves to the large diameter end of the pressure relief elbow, the through-hole suction cup reaches the maximum suction force on the glass plate. When the distance between the outer plate and the pressure relief elbow becomes greater, the suction force required to pull the blocking ball to the large diameter end of the pressure relief elbow becomes greater, so that the heavier the glass plate adsorbed by the through-hole suction cup, the greater the suction force of the through-hole suction cup on the glass plate.

[0034] 3. The present invention is provided with components such as a groove wheel, a movable frame, a one-way push plate, an inner turntable and an air transfer groove. When the suspension connecting frame controls the mounting ring to drive the through-hole suction cup downward to contact the glass plate, the suspension connecting frame continues to move relatively, and the upper tube moves downward relative to the lower tube, so that the push rod drives the one-way push plate upward by pushing the movable frame to rotate the groove wheel, and the groove wheel drives the air transfer groove on the circumferential surface of the inner turntable to connect with the air duct, which can provide suction to the through-hole suction cup, and the through-hole suction cup applies suction to the glass plate. After the glass plate moves to the designated position and is put down, when the suspension connecting frame continues to move downward, the push rod pushes the movable frame and the one-way push plate upward again, so that the groove wheel rotates 90 degrees, so that the air transfer groove and the air duct are misaligned, so that the through-hole suction cup is separated from the adsorption of the glass plate, and the glass plate can be put down.

[0035] 4. The present invention provides an adjustment ring, an adjustment rod, an adjustment sleeve, and other components. When the adjustment ring rotates, the adjustment sleeve is driven to rotate synchronously. The adjustment rod slides within the adjustment sleeve to change the distance between the through-hole suction cup and the axis of the mounting ring, so that the through-hole suction cup can adapt to glass plates of different sizes.

DETAILED DESCRIPTION

[0046] The following is combined with Figures 1-9 The present invention is described in further detail.

[0047] The embodiment of the present invention discloses a transport device for automatically adjusting adsorption force for glass processing. Figures 1-9As shown, it includes a suspension connecting frame 1, which is connected to a control structure that can control lifting and horizontal movement, so that the suspension connecting frame 1 can move up and down and horizontally, and can drive the suspension connecting frame 1 to change its position. An elastically retractable mounting ring 2 is installed at the lower end of the suspension connecting frame 1, and a plurality of suction cup structures 3 are installed at the lower retractable end of the mounting ring 2. The suction cup structure 3 can adsorb the glass plate it contacts. The suspension connecting frame 1 can control the glass plate to move to a specified position and can place the glass plate to the corresponding position.

[0048] The mounting ring assembly 2 includes a mounting ring 21, an upper ring 22 and multiple vertical poles 23. The upper ring 22 is coaxially located on the upper side of the mounting ring 21. The lower ends of the vertical poles 23 are fixed to the mounting ring 21. The upper ring 22 is slidably sleeved on the outer surface of the vertical pole 23. The vertical pole 23 is located on the upper side of the upper ring 22 and is slidably sleeved with a ring 24. The upper surface of the ring 24 is elastically connected to the upper end of the vertical pole 23. The ring 24 and the upper end of the vertical pole 23 are elastically connected by a spring. The ring 24 has a tendency to move away from the upper end of the vertical pole 23.

[0049] The inner ring surface of the collar 24 is convex, and the portion of the vertical rod 23 located on the upper side of the upper ring 22 is provided with a groove structure that cooperates with the convex structure of the collar 24. The groove structure of the vertical rod 23 limits the movement range of the collar 24, so that when the mounting ring 21 moves upward relative to the upper ring 22, the elastic connection between the collar 24 and the vertical rod 23 will not exert resistance on the movement of the mounting ring 21. When the suction cup structure 3 adsorbs the glass plate and suspends it in the air, the glass plate pulls the mounting ring 21 and the vertical rod 23 downward, causing the vertical rod 23 to elastically move downward close to the collar 24.

[0050] An air suction providing structure 4 is installed inside the suspension connecting frame 1 .

[0051] The suction cup structure 3 includes a through-hole suction cup 31, a lower bend tube 32 and an upper bend tube 33. The through-hole suction cup 31 is located on the lower side of the mounting ring 21. The through-hole suction cup 31 is connected and installed with the lower end of the lower bend tube 32. The other end of the lower bend tube 32 rotates and passes through the bottom surface of the mounting ring 21. The lower bend tube 32 is located on the upper side of the mounting ring 21 and is rotatably connected to the lower end of the upper bend tube 33. The upper bend tube 33 can rotate relative to the upper bend tube 33 and the mounting ring 21.

[0052] The outer ring surface of the mounting ring 21 is sleeved with a power-rotating adjustment ring 211 , and the mounting ring 21 is equipped with a motor that drives the power rotation of the adjustment ring 211 . The two ends of the lower bend pipe 32 are vertically arranged, and the middle position of the lower bend pipe 32 is horizontally arranged.

[0053] An adjusting rod 212 is fixed to the upper surface of the horizontal part of the lower bend tube 32, and an adjusting sleeve 213 is slidably sleeved on the outer surface of the adjusting rod 212. The adjusting sleeve 213 is fixed to the outer ring surface of the adjusting ring 211, and the extension line of the adjusting sleeve 213 coincides with the axis of the adjusting ring 211. When the adjusting sleeve 213 rotates with the adjusting ring 211, the adjusting rod 212 moves in the adjusting sleeve 213 to change the distance between the through-hole suction cup 31 and the axis of the mounting ring 21, so that the through-hole suction cup 31 can adsorb glass plates of different sizes.

[0054] The air supply structure 4 includes a negative pressure structure 41 capable of powered air extraction and a retractable air transmission structure 42 . The negative pressure structure 41 is connected to the suspension connecting frame 1 , and the negative pressure structure 41 is connected to the retractable end of the air transmission structure 42 and installed in communication.

[0055] The upper end of the suction cup structure 3 is connected to the lower telescopic end of the air transmission structure 42 and installed, and the suction cup structure 3 can absorb the glass it contacts.

[0056] The air transmission structure 42 is equipped with a negative pressure regulating structure 43 which can control the maximum negative pressure inside the suction cup structure 3 . The negative pressure regulating structure 43 is connected to the telescopic end of the mounting ring 2 .

[0057] The air transmission structure 42 includes an upper tube 421 and a lower tube 422. The upper tube 421 is slidably connected to the outer surface of the lower tube 422. The lower tube 422 is located at the lower side of the upper tube 421 and is connected to an end plate 423. The upper end of the upper bend pipe 33 is connected and installed with the lower end of the end plate 423, and the end plate 423 is connected and installed with the negative pressure regulating structure 43.

[0058] The negative pressure regulating structure 43 is connected to the upper ring 22 , the suction cup structure 3 is connected to the mounting ring 21 , and the upper surface of the upper ring 22 is fixed to the suspension connecting frame 1 .

[0059] The negative pressure regulating structure 43 includes a pressure relief elbow 431 and a blocking ball 432 . The lower end of the pressure relief elbow 431 is connected to the end plate 423 and installed.

[0060] The upper end of the pressure relief bend 431 is horizontal, and the horizontal end of the pressure relief bend 431 is divided into two parts with different inner diameters. The large diameter end of the horizontal part of the pressure relief bend 431 is located between the small diameter end and the axis of the end plate 423.

[0061] The blocking ball 432 is slidably inserted into the inside of the small-diameter end of the horizontal part of the pressure relief elbow 431. When the blocking ball 432 is located inside the small-diameter end of the pressure relief elbow 431, the blocking ball 432 can block the pressure relief elbow 431. A horizontal elastic telescopic rod 433 is fixed to the end of the blocking ball 432 away from the end plate 423. The large-diameter end of the horizontal elastic telescopic rod 433 has a smaller diameter than the internal diameter of the small-diameter end of the horizontal end of the pressure relief elbow 431. An outer plate 434 is fixed to the end of the horizontal elastic telescopic rod 433 located outside the pressure relief elbow 431. The horizontal elastic telescopic rod 433 has a tendency to contract, which has the function of pulling the blocking ball 432 closer to the outside The outer plate 434 is elastically connected to the upper surface of the pressure relief bend 431 horizontally, and an inner shaft 435 is fixedly passed through the front of the outer plate 434. After the through-hole suction cup 31 adsorbs the glass plate, the negative pressure between the end plate 423 and the pressure relief bend 431 has a tendency to pull the blocking ball 432 to move toward the large diameter end of the pressure relief bend 431. After the blocking ball 432 moves to the large diameter end of the pressure relief bend 431, the pressure relief bend 431 and the end plate 423 can be depressurized, and the maximum negative pressure in the end plate 423 and the pressure relief bend 431 is limited, thereby limiting the maximum suction force of the through-hole suction cup 31 on the glass plate.

[0062] The interior of the upper end of the upper tube 421 is adapted to the exterior of the lower tube 422 in size, and a gap is set between the inner wall of the lower end of the upper tube 421 and the outer surface of the lower tube 422. At the same time, the lower end of the upper tube 421 cooperates with the lower tube 422 so that the space of the large diameter part of the upper tube 421 is not connected to the outside. The lower tube 422 is located on the side of one end of the interior of the upper tube 421 and is provided with an air vent 424. When the air vent 424 of the lower tube 422 is located at the large diameter end part of the upper tube 421, the air in the large diameter end part of the upper tube 421 is evacuated from the lower tube 422 through the air vent 424, and the negative pressure structure 41 is connected and installed to the interior of the large diameter end of the upper tube 421.

[0063] A limiting ring 425 is slidably inserted into the large diameter end of the upper tube 421, and the limiting ring 425 is slidably sleeved on the outer surface of the lower tube 422. The inner ring surface of the limiting ring 425 is convex, and the outer surface of the lower tube 422 is provided with a long groove structure that is compatible with the convex structure of the limiting ring 425. When the lower tube 422 moves relative to the upper tube 421, the limiting ring 425 slides in the upper tube 421, and at the same time, the limiting ring 425 slides on the surface of the lower tube 422. The long groove structure of the lower tube 422 limits the range of movement of the limiting ring 425 relative to the lower tube 422.

[0064] The upper end of the upper curved pipe 33 is connected and installed with the lower telescopic end of the air transmission structure 42 .

[0065] A track frame 436 is installed on the upper surface of the upper ring 22 , and the inner shaft 435 is inserted into the track frame 436 .

[0066] The upper end of the track frame 436 is arranged vertically, and the lower end of the track frame 436 is arranged inclined toward a side away from the axis of the end plate 423.

[0067] When the suspension connecting frame 1 drives the through-hole suction cup 31 to contact the glass plate, the through-hole suction cup 31 can absorb the glass plate. When the suspension connecting frame 1 drives the through-hole suction cup 31 to move upward in the air, the gravity of the mounting ring 21 and the glass plate drives the upper end of the vertical rod 23 to elastically approach the sleeve ring 24, so that the end plate 423 and the pressure relief elbow 431 drive the inner through shaft 435 to move downward relative to the track frame 436, driving the outer plate 434 to move away from the pressure relief elbow 431, and the glass plate is lifted up. The heavier the glass plate, the greater the distance the inner through shaft 435 moves downward relative to the track frame 436. At the same time, the greater the distance the outer plate 434 is away from the pressure relief bend 431, the greater the negative pressure required for the negative pressure in the pressure relief bend 431 to drive the blocking ball 432 into the large-diameter end of the pressure relief bend 431, and the greater the suction force of the through-hole suction cup 31 on the glass plate. The lighter the glass plate, the smaller the maximum negative pressure in the end plate 423, so that the suction force exerted by the through-hole suction cup 31 on the glass plate changes with the gravity of the glass plate.

[0068] The negative pressure structure 41 includes an air disc 411 and an inner turntable 412. The inner turntable 412 is rotatably inserted into the inside of the air disc 411. The thickness of the inner turntable 412 is less than the width of the inner wall of the air disc 411, so that a negative pressure cavity is formed between the inner turntable 412 and the inner wall of the air disc 411. A shaft 413 is fixed through the axis of the inner turntable 412. A negative pressure pump 414 is installed on the side of the air disc 411 away from the inner turntable 412. The negative pressure pump 414 can pump negative pressure into the air disc 411.

[0069] The shaft 413 is located on the outside of the gas disc 411 and is fixedly sleeved with a groove wheel 415 at one end. Four evenly distributed groove-shaped structures are opened on the circumferential side of the groove wheel 415. A movable frame 416 that moves up and down is provided on one side of the circumferential surface of the groove wheel 415. The movable frame 416 is elastically slidably connected to the end face of the gas disc 411. The elastic connection between the movable frame 416 and the gas disc 411 is connected by a spring, which has a tendency to push the movable frame 416 to move downward. The movable frame 416 moves up and down relative to the gas disc 411. The movable frame 416 is located on the upper side of the upper tube 421, and a push rod 417 is fixed to the upper end of the lower tube 422. The push rod 417 is located on the lower side of the movable frame 416.

[0070] A one-way push plate 418 is provided on the side of the groove wheel 415 close to the movable frame 416. The one-way push plate 418 is elastically rotatably connected to the side of the movable frame 416 close to the air disk 411. The one-way push plate 418 rotates upward in one direction relative to the movable frame 416. When the lower tube 422 moves upward relative to the upper tube 421, the push rod 417 is pushed to move upward relative to the movable frame 416. After the push rod 417 pushes the movable frame 416, the one-way push plate 418 is driven to move upward. When the one-way push plate 418 moves upward, it pushes the groove wheel 415 to rotate 90 degrees. When the push rod 417 moves downward, the one-way push plate 418 rotates upward relative to the movable frame 416 without applying thrust to the groove wheel 415. The elastic connection between the movable frame 416 and the air disk 411 has a tendency to move downward.

[0071] Two air transfer grooves 419 are provided on the circumferential surface of the inner turntable 412. A ventilation pipe 4110 is installed on the side of the air disc 411 close to the upper tube 421. The other end of the ventilation pipe 4110 is connected and installed with the large diameter end of the upper tube 421. The ventilation pipe 4110 is located on the lower side of the shaft 413. Each time the push rod 417 moves upward, it can drive the groove wheel 415 and the inner turntable 412 to rotate 90 degrees. When the air transfer groove 419 is connected with the ventilation pipe 4110, the negative pressure pump 414 can generate negative pressure between the large diameter end of the lower tube 422 and the lower tube 422 through the air transfer groove 419 and the ventilation pipe 4110. When the push rod 417 moves upward again, the inner turntable 412 rotates 90 degrees again, causing the air transfer groove 419 and the ventilation pipe 4110 to be misaligned, so that the through-hole suction cup 31 is separated from the adsorption of the glass plate.

[0072] A pressure relief hole 4111 is provided at one end of the air disc 411 near the upper tube 421. The pressure relief hole 4111 is arranged at 90 degrees to the upper end of the vent pipe 4110 and the axis of the air disc 411. When the air transfer groove 419 and the vent pipe 4110 are misaligned, the air transfer groove 419 is connected to the pressure relief hole 4111 to prevent the negative pressure pump 414 from being damaged.

[0073] The upper side of the groove wheel 415 is in contact with a pressure wheel 4151, and the pressure wheel 4151 is rotatably connected to an elastic vertical telescopic rod 4152. The elastic vertical telescopic rod 4152 is fixed to the air disc 411. The elastic vertical telescopic rod 4152 has a tendency to push the pressure wheel 4151 to move downward, so that the pressure wheel 4151 cooperates with the groove structure of the groove wheel 415. At this time, the air transmission groove 419 is connected to the vent pipe 4110 or the pressure relief hole 4111 to ensure that the groove wheel 415 will only rotate when the one-way push plate 418 moves upward.

[0074] The working principle is: the suspension connecting frame 1 controls the installation group ring 2 to move up and down, controls the suction cup structure 3 to move to the upper side of the glass plate, and the negative pressure structure 41 applies suction to the suction cup structure 3 through the air transmission structure 42. When the suction cup structure 3 contacts the glass plate, the suction cup structure 3 adsorbs the glass plate, and the maximum suction force of the suction cup structure 3 on the glass plate is controlled by the negative pressure adjustment structure 43. Then, the suspension connecting frame 1 controls the glass plate adsorbed by the suction cup structure 3 to move to the specified position. After the glass plate is put down, the negative pressure structure 41 is controlled to stop applying suction to the suction cup structure 3, so that the suction cup structure 3 is no longer adsorbed on the glass plate.

[0075] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
