Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass plate cutting technology, and in particular to a glass plate cutting device. Background Technology
[0002] Tempered glass screen protectors are protective films applied to mobile phone screens. Structurally, they mainly consist of an outer layer of tempered glass: high-definition glass that has undergone tempering treatment, providing screen protection and impact resistance; a middle layer of plastic or resin: increasing toughness and preventing injury from flying glass shards if the glass breaks; and a bottom adhesive layer: using adhesive to bond to the screen for a secure hold. During the production of tempered glass screen protectors, the initial step is processing the outer tempered glass layer. In addition to cutting the glass sheets, the cut glass sheets are then individually transferred to tempered glass screen protector polishing equipment for further polishing.
[0003] After the glass plates are polished, a feeding device needs to be installed on the tempered film polishing equipment to allow the polished glass plates to be inserted one by one into the material box.
[0004] Currently, grinding fixtures generally use a turntable to pick up and grind glass plates, followed by a transfer tray with a similar structure to hold the glass plates removed from the grinding mechanism. The structure of this transfer tray is as follows: Figure 1 As shown, the entire structure is a rotating turntable, divided into three placement positions, each at a 120° angle. Each placement position is separated by a center point, with one placement station on one side and two on the other, forming a centrally symmetrical structure. The main purpose is to effectively and rationally utilize the turntable's area. However, with this design, when using suction cups to pick up glass plates from a single placement position on the turntable in one go, three equally spaced suction cups are required. The material box is used to store the polished glass plates, such as... Figure 2 As shown, the material box has three interlocking chambers for easy transportation and storage, but the chambers are all close together, which does not match the spacing on the turntable. If they are inserted into the chambers one by one, the material can be fed, but the efficiency is low. If three are to be inserted at the same time in batches, a feeding device with adjustable spacing is required.
[0005] Therefore, it is necessary to design a feeding device that meets the design requirements. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a glass plate feeding device that can meet the requirements of varying spacing.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A glass plate feeding device includes a first feeding block, a second feeding block, a third feeding block, and a first base plate fixedly mounted on a tempered glass film polishing device. The first base plate has a first linear module that moves along the Y-axis and is driven by a first motor. A second base plate is fixedly connected to a movable seat of the first linear module.

The second and third material picking blocks are movably installed on the rotating rod and the guide rod through bushings. A rodless cylinder is arranged between the connecting plates along the direction of the guide rod. The movable seat of the rodless cylinder is connected to the third material picking block. The second and third material picking blocks are connected. Vacuum suction cups are provided at the bottom of the first, second, and third material picking blocks. Vacuum ports for connecting to vacuum pumps are provided on the first, second, and third material picking blocks. The vacuum ports are connected to the corresponding vacuum suction cups.
[0009] Preferably, a trigger plate and a photoelectric sensor adapted to the trigger plate are respectively provided at the moving trajectories of the first linear module and the second linear module.
[0010] Preferably, at least one hydraulic buffer is provided on the connecting piece directly opposite the third material receiving block.
[0011] Preferably, at least one adjusting bolt is screwed into the end face of the first material taking block facing the second material taking block and the end of the third material taking block facing the connecting piece.
[0012] Preferably, the second material picking block is provided with a bayonet, the diameter of the inner cavity of the bayonet is larger than the diameter of the opening, the third material picking block is provided with a "T"-shaped locking protrusion, the top of the locking protrusion is placed in the inner cavity of the bayonet, the diameter of the top of the locking protrusion is larger than the opening diameter of the bayonet, so that the locking protrusion cannot be disengaged from the opening of the bayonet, and the rotating rod and the guide rod are fitted with a spring between the second material picking block and the third material picking block.
[0013] Preferably, the third base is provided with a solenoid valve for connecting an external vacuum pump. The solenoid valve is connected to a vacuum port via a three-way pipe and is connected to a vacuum sensor.

Therefore, it can effectively perform the material feeding work. In particular, by relying on the air rod as the driving source for changing the spacing, the two spacings can be switched quickly, improving the material feeding efficiency.

[0023] like Figures 3 to 5 As shown, this embodiment provides a glass plate feeding device, including a first feeding block 1, a second feeding block 2, a third feeding block 3, and a first substrate 4 fixedly installed on a tempered film polishing device. The first substrate 4 is provided with a first linear module 6 that moves along the Y-axis and is driven by a first motor 5. A second substrate 7 is fixedly connected to the movable seat of the first linear module 6. A second linear module 9 that moves along the Z-axis and is driven by a second motor 8 is provided on the second substrate 7. A third substrate 10 is fixedly connected to the movable seat of the second linear module 9. A fourth substrate 11 is horizontally mounted on the third substrate 10. A third motor 12 is mounted on the fourth substrate 11, and a rotating rod 13 is mounted on the fourth substrate 11 via a bearing seat. One end of the rotating rod 13 is connected to the rotating shaft of the third motor 12. The rotating rod 13 has connecting pieces 14 at both ends, and guide rods 15 are connected to the connecting pieces 14. The first material picking block 1 is fixedly installed on one end of the rotating rod 13 and the guide rod 15. The second material picking block 2 and the third material picking block 3 are movably installed on the rotating rod 13 and the guide rod 15 through bushings. A rodless cylinder 16 is arranged between the connecting pieces 14 along the direction of the guide rod 15. The movable seat of the rodless cylinder 16 is connected to the third material picking block 3. The second material picking block 2 is connected to the third material picking block 3. A vacuum suction cup 17 is provided at the bottom of the first material picking block 1, the second material picking block 2 and the third material picking block 3. A vacuum port 18 for connecting a vacuum pump is provided on the first material picking block 1, the second material picking block 2 and the third material picking block 3. The vacuum port 18 is connected to the corresponding vacuum suction cup.
[0024] The main feature of this embodiment is that it can arrange the first picking block 1, the second picking block 2, and the third picking block 3 side by side to meet the spacing requirements of the material box, and it can also move the second picking block 2 and the third picking block 3 to the other side to meet the spacing requirements of the turntable. Therefore, it can effectively perform the material feeding work. Among them, relying on the air rod as the driving source to change the spacing, the two spacings can be switched quickly, improving the feeding efficiency.
[0025] In actual operation, the first linear module 6 on the first substrate 4 moves to the top of the turntable. Then the second linear module 9 moves down. When picking up material from the turntable, the second picking block 2 and the third picking block 3 are moved to the other side relative to where the first picking block 1 is located by the push of the leverless cylinder 16. This corresponds to the position of the glass plate on the turntable. Under the rotation of the third motor 12, the first picking block 1, the second picking block 2, and the third picking block 3 are kept in a parallel state. After the second linear module 9 moves down to the bottom, the vacuum suction cup 17 adheres to the glass plate. The external vacuum pump is turned on to start suction, which can hold the glass plate. Once the glass plate is sucked in, the first linear module 6 and the second linear module 7 retract completely, positioning the first picking block 1, the second picking block 2, and the third picking block 3 directly above the material box. Then, the third motor 12 rotates, bringing the first picking block 1, the second picking block 2, and the third picking block 3 into a vertical position, ensuring the sucked glass plate is vertical. Under the action of the rodless cylinder 16, the second picking block 2 and the third picking block 3 return to one end of the first picking block 1, placing them side-by-side. Under the action of the second linear module 9, they move vertically downwards until one end of the glass plate is inserted into the material tray. Once one end of the glass plate is inserted, the vacuum suction is removed, and the first linear module 1 and the second linear module 2 return to their original positions. The turntable will then rotate 120° to move the next placement position to the previously picked-up location.
[0026] Furthermore, for precise movement, trigger pieces 19 and photoelectric sensors 20 adapted to the trigger pieces 19 are respectively installed at the movement trajectories of the first linear module 1 and the second linear module 2. This allows for precise correction of the movement position by triggering the trigger pieces 19 and the photoelectric sensors 20, ensuring accurate movement.
[0027] Furthermore, since the push is performed by the leverless cylinder 16, in order to avoid a hard collision with the connecting piece 14 or other components when it moves to the end, the connecting piece 14 in this embodiment is provided with at least one hydraulic buffer 21 opposite to the third material taking block 3. In this way, when the leverless cylinder 16 moves outward, it can rely on the hydraulic buffer 21 as a collision buffer to reduce the intensity of the collision.
[0028] Furthermore, at least one adjusting bolt 22 is screwed into the end face of the first material picking block 1 facing the second material picking block 2 and the end face of the third material picking block 3 facing the connecting piece 14, respectively. In this way, the distance between the first material picking block 1 and the second material picking block 2 can be adjusted according to the extension distance of the adjusting bolt 22. When the third material picking block 3 moves to the other side, the distance between the third material picking block 3 and the connecting piece 14 is adjusted. This is mainly to facilitate fine adjustment of the distance.
[0029] Meanwhile, regarding the connection between the second material picking block 2 and the third material picking block 3, specifically, the second material picking block 2 can be provided with a bayonet 23, the diameter of the inner cavity of the bayonet 23 being larger than the diameter of the opening, and the third material picking block 3 can be provided with a "T"-shaped locking protrusion 24, the top of the locking protrusion 24 being placed in the inner cavity of the bayonet 23, and the diameter of the top of the locking protrusion 24 being larger than the opening diameter of the bayonet 23, so that the locking protrusion 24 cannot be disengaged from the opening of the bayonet 23. The rotating rod 13 and the guide rod 15 are fitted with a spring 25 between the second material picking block 2 and the third material picking block 3. This design can satisfy the requirement that the second material picking block 2 moves together with the third material picking block 3, and the spring can also play a role in buffering and shock absorption when the second material picking block 2 touches the adjusting bolt.
[0030] Furthermore, in this embodiment, the third base 10 is equipped with a solenoid valve 26 for connecting an external vacuum pump. The solenoid valve 26 is connected to the vacuum port 18 via a three-way pipe 27 and is connected to a vacuum sensor 28 (pressure transmitter). The function of the vacuum sensor 28 is to detect the vacuum pressure value in real time when the vacuum suction cup 17 picks up the glass plate. When the glass plate is being picked up, if it is found that the picking action has been completed but no negative pressure value is detected, it can be determined that either the glass plate is broken or the glass plate has not been picked up. This characteristic is used to check whether the glass plate is damaged or whether the material has been successfully picked up. This information can be directly fed back to the main control system of the tempered glass film polishing equipment for subsequent early warning work.
[0031] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
