Description

Technical Field

[0001] The invention relates to the technical field of tempered glass production, in particular to a transfer device used for tempered glass processing. Background Art

[0002] Tempered glass is a kind of prestressed glass. In order to improve 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. During the manufacturing or use process, tempered glass usually needs to be transported to other designated locations, but tempered glass is easily broken due to collisions at the four corners, and during transportation, it is also easy to cause damage that cannot be seen from the outside, affecting the safety of subsequent use. For this reason, there are many public technologies on the market that propose improvement methods, such as a tempered glass transport device, including a base, a protective cavity with an upper opening in the base, and a protective cavity A first airbag is fixed to the side and bottom plate of the protection cavity, a connecting block is fixedly connected to the right end of the base, a rotating cavity with left and upper openings is arranged in the connecting block, front and rear end walls of the rotating cavity are rotatably connected to a rotating shaft, a baffle is fixedly connected to the rotating shaft, and a second airbag is fixedly arranged on the left end of the baffle, and the first airbag and the second airbag are inflated to fix and buffer tempered glass of different sizes and shapes; an air pump is arranged to draw in outside air, and the air is transported to the first airbag and the second airbag through a connecting valve connected to the air pump; during the inflation process and the transportation process, the air can be slowly discharged when the pressure increases through a pressure valve connected to the connecting valve, so as to buffer the force on the tempered glass and avoid damage to the glass.

[0003] Another example is a tempered glass transfer and protection structure, which includes a movable base and a supporting frame. The movable base includes a base body and a universal wheel assembly. The universal wheel assembly is installed on the lower end surface of the base body. The supporting frame mounting frame is at the center of the upper end surface of the base body. A first supporting plate and a second supporting plate are respectively arranged on both sides of the supporting frame. A first buffer spring group is installed between the first supporting plate and one side of the supporting frame, and a second buffer spring group is installed between the second supporting plate and the other side of the supporting frame. A clamping assembly is also installed on the upper end of the supporting frame. The structural design proposed in the disclosed technology is novel and easy to use. It can effectively fix the tempered glass to prevent it from tipping over, thereby improving the efficiency of tempered glass transfer.

[0004] However, in the prior art including the above-mentioned disclosed technology, when the tempered glass is transported, the tempered glass is usually transferred to the transport device and removed from the transport device by manual handling, which is troublesome and laborious. There are also vacuum suction cup adsorption and lifting structures suitable for large pieces of tempered glass, but they are usually separated from the transport device, resulting in the hoisting device also needing to move with the transport device during transportation, which is very inconvenient. In addition, when the existing vacuum suction cup adsorbs and transports the tempered glass, the glass is only sucked by the adsorption force of the vacuum suction cup, and there is no safety insurance measure. Once the vacuum suction cup fails, the tempered glass will inevitably fall and be damaged, and even cause injuries; In summary, it is necessary to optimize and improve the structure of the transfer device used for tempered glass processing.

Since it is not the key improvement direction of the technical solution of this embodiment, it is not described here; In order to prevent the handling device from tipping forward when carrying the tempered glass, a counterweight structure for balancing weight is provided inside the counterweight box 4. The counterweight structure is a counterweight block 13. The counterweight block 13 is fixedly connected to the upper wall of the rear chassis 1 and is located inside the counterweight box 4.

In order to adjust the counterweight position of the counterweight block 13, a first translation drive structure for adjusting the counterweight effect is arranged between the front chassis 2 and the counterweight box 4. The first translation drive structure includes two groups of fixed sleeves 5, sliding rods 12 and two groups of first electric telescopic rods 6. The two groups of fixed sleeves 5 are fixedly connected to the upper wall of the front chassis 2 and are respectively located on the left and right sides of the manipulator 7.

In order to adsorb the tempered glass to realize the handling operation, the handling device includes a substrate 8, a driving motor is provided at one end of the manipulator 7 away from the front chassis 2, the substrate 8 is fixedly connected to the end of the extended shaft of the driving motor, an adsorption structure for adsorbing the tempered glass is provided on the substrate 8, and the adsorption structure is connected to the negative pressure pump through an air pipe, and the adsorption structure includes multiple groups of negative pressure bases 9, and the multiple groups of negative pressure bases 9 are fixedly connected to the upper wall of the substrate 8 in a rectangular array, and the ends of the multiple groups of negative pressure bases 9 facing the substrate 8 all penetrate the substrate 8 and extend to the bottom of the substrate 8, and the ends of the negative pressure bases 9 extending below the substrate 8 are fixedly connected with vacuum suction cups 14, and the upper ends of the negative pressure bases 9 are connected to the negative pressure pump through an air pipe. During operation, the substrate 8 is controlled to be close to the tempered glass until the multiple groups of vacuum suction cups 14 contact the surface of the tempered glass, and the air between the vacuum suction cups 14 and the tempered glass is sucked away by the negative pressure pump, so that the tempered glass is firmly adsorbed; In order to limit the tempered glass in the vertical state, the rear wall of the substrate 8 is fixedly connected with a supporting structure for holding the tempered glass from below when carrying the tempered glass.

The lower ends of the multiple groups of stop pins 26 extend toward the lower side of the substrate 8 and the extended length does not exceed the thickness of the tempered glass. When the substrate 8 sucks the tempered glass through the vacuum suction cup 14, if the tempered glass is initially flat, the multiple groups of stop pins 26 press against the side of the tempered glass facing the device. If the tempered glass is initially tilted, the robot 7 drives the substrate 8 upward. Flip until the substrate 8 is flush with the surface of the tempered glass, and then move close to the tempered glass. At this time, the multiple groups of stop pins 26 are in contact with the bottom end of the tempered glass. After the tempered glass is sucked and lifted by the vacuum suction cup 14, the bottom end of the tempered glass in a vertical or inclined state is blocked by the multiple groups of stop pins 26, which plays a role of supporting the bottom, and prevents the tempered glass from sliding from this side due to the failure of the vacuum suction cup 14. The specific position of the multiple groups of stop pins 26 can be selected according to the bottom position of the shelf for placing tempered glass at the production site and the specific position of the pad 28 in the silo, so as to avoid the interference between the stop pins 26 and the shelf and the pad 28 when taking or placing; In order to adapt to tempered glass of different heights and widths, the left and right side walls and the front wall of the substrate 8 are provided with a limit seat 10, and a second translation driving structure for driving the limit seat 10 to move is provided between the limit seat 10 and the substrate 8. The second translation driving structure includes two groups of second electric telescopic rods 21 and two groups of guide rods 19. Two groups of mounting holes 20 and two groups of guide holes 18 are provided on one side of the substrate 8 facing the limit seat 10.

The axis extension lines of 17 all intersect with the axis line of the rotating shaft 15, and the multiple groups of sliding wheels 17 are evenly distributed along the circumference with the axis center of the rotating shaft 15 as the center. The horizontal height of the upper wall of the sliding wheel 17 is higher than the anti-slip plate 16. After the adsorption structure is adsorbed, the anti-slip plate 16 rotates until the sliding wheel 17 contacts the side of the tempered glass away from the substrate 8. When the tempered glass is transported horizontally, the anti-slip plate 16 is located below the tempered glass to prevent the tempered glass from falling downward. When the tempered glass is transported vertically, the anti-slip plate 16 is used to block the side of the tempered glass away from the substrate 8 to prevent the tempered glass from tipping toward the side away from the substrate 8. Before unloading, the anti-slip plate 16 rotates to a state where the gap 1601 is parallel to the side of the substrate 8.

[0023] Working principle: After the counterweight 13 is set, the weight of the counterweight 13 ensures that the handling device will not tip forward when handling the tempered glass, thereby improving the safety of the operation; when the handling device is handling, the connection point between the manipulator 7 and the front chassis 2 is used as the fulcrum to form a lever with the rear chassis 1 and the handling device at both ends. When there is no tempered glass on the silo, when handling heavier tempered glass, the first electric telescopic rod 6 can be extended by extending the shaft to drive the rear chassis 1 to move away from the fulcrum, thereby increasing the length of the lever arm between the counterweight 13 and the fulcrum, effectively improving the counterweight effect of the counterweight 13.

The specific positions of the multiple sets of stop pins 26 can be selected according to the bottom position of the shelf used to place the tempered glass at the production site and the specific position of the pad 28 in the silo, so as to avoid the interference between the stop pins 26 and the shelf and the pad 28 when taking or placing; the three sets of limit seats 10 can all be driven by the second translation drive structure to move closer to or away from the substrate 8, so as to adapt to tempered glass of different sizes and have a wide range of applications; after the adsorption structure is completed, the anti-slip plate 16 rotates to the sliding wheel 17 to contact the side of the tempered glass away from the substrate 8, and the tempered glass When transporting horizontally, the anti-slip plate 16 is located below the tempered glass to prevent the tempered glass from falling downwards. When transporting the tempered glass vertically, the anti-slip plate 16 is used to block the side of the tempered glass away from the substrate 8 to prevent the tempered glass from tipping toward the side away from the substrate 8. Before unloading, the anti-slip plate 16 rotates to a state where the gap 1601 is parallel to the side of the substrate 8. At this time, when the substrate 8 leaves the tempered glass, the anti-slip plate 16 does not contact the tempered glass; wherein, the extension and retraction of the extension shaft of the third electric telescopic rod 24 can drive the rack plate 23 to move axially along the extension shaft of the third electric telescopic rod 24, and then drive the gear 25 meshing therewith to rotate through multiple sets of teeth 2301, so as to achieve the purpose of driving the rotating shaft 15 and the anti-slip plate 16 to rotate.
