Description

Technical Field

[0001] This utility model relates to the field of glass flipping technology, specifically a flipping device for photovoltaic glass processing. Background Technology

[0002] Photovoltaic glass often requires double-sided processing or testing during the manufacturing process, so it is necessary to realize the automatic flipping of glass sheets in the production line.

[0003] Existing flipping devices include two lifting and rotating clamping components. After the two clamping components have clamped the photovoltaic glass, the photovoltaic glass needs to be moved upwards first, and then the two clamping components rotate simultaneously to flip the photovoltaic glass. Since the two clamping components are driven to rotate by their respective motors, during continuous operation, errors can cause their rotations to be inconsistent. As these errors accumulate, the two clamping components need to be repositioned and matched frequently, making the device relatively cumbersome and affecting production efficiency.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0020] like Figure 1-7 As shown, a flipping device for photovoltaic glass processing includes a support frame 3, a lifting unit, a clamping unit, and a rotating unit. The lifting unit is mounted on the support frame 3. The lifting unit has two lifting ends. The clamping unit includes two clamping ends, which are located on the two lifting ends respectively. It also includes a connecting rod 4, with a fixed seat 5 at each end of the connecting rod 4. The fixed seat 5 has a through hole, and mounting plates 6 are provided on the upper and lower sides of the clamping end. A fixed rod 7 that is slidably connected to the fixed seat 5 is provided between the two mounting plates 6. Springs 8 are respectively sleeved on the fixed rod 7 and located on both sides of the fixed seat 5. A contact sensor 9 is provided on the inner middle part of the connecting rod 4; The rotating unit is mounted on the lifting unit. The rotating unit is used to drive one of the clamping ends to rotate, while the other clamping end rotates following the first clamping end under the action of the connecting rod 4.

[0021] Furthermore, the lifting unit includes a U-shaped movable frame 10, with rails 11 on both sides of the movable frame 10. The support frame 3 is provided with a slide groove 12 for sliding the rails 11. The two slide grooves 12 are connected by a partition 13. A first lead screw 14 is provided between the support frame 3 and the partition 13. A first motor 15 is provided below the support frame 3 to drive the first lead screw 14 to rotate. The first lead screw 14 is threadedly connected to the movable frame 10.

[0022] When it is necessary to control the movable frame 10 to move upward, the first motor 15 needs to be started. The first motor 15 drives the first lead screw 14 to rotate. Then, through the threaded connection between the first lead screw 14 and the movable frame 10, and the sliding connection between the track 11 and the slide 12, the movable frame 10 is driven to move vertically upward. When it is necessary to control the movable frame 10 to move downward, it is only necessary to control the output end of the first motor 15 to rotate in the opposite direction. The upward and downward positions of the movable frame 10 are determined according to the positions after debugging. Therefore, upper limit and lower limit devices can be set on the slide 12 respectively, so that the movable frame 10 stops moving when it moves upward or downward to the target position.

[0023] Furthermore, the two clamping ends in the clamping unit are respectively set at both ends of the movable frame 10. The clamping end includes a fixed frame 16. A sleeve 17 is provided on one side of the fixed frame 16. The sleeve 17 is rotatably connected to the movable frame 10. An abutment frame 18 is provided on one side of the fixed frame 16. A groove 19 is opened on one side of the abutment frame 18. The groove 19 is only open on one side. Two guide rods 20 that are slidably connected to the fixed frame 16 are provided on the outer side of the abutment frame 18. A slide block 21 is provided on one side of the abutment frame 18. The slide block 21 passes through the fixed frame 16 and is located inside the fixed frame 16. A second lead screw 22 is provided inside the fixed frame 16. A second motor 23 for driving the second lead screw to rotate is provided on the outer side of the fixed frame 16.

[0024] Two clamping ends are located on either side of the conveyor belt 2. The position of the glass plate 1 on the conveyor belt 2 has been adjusted. During the transport of the glass plate 1, when the front end of the glass plate 1 contacts the contact sensor 9, the contact sensor 9 senses that the glass plate 1 is in position and then transmits the signal to the control system. The control system controls the conveyor belt 2 to stop moving. Subsequently, the second motors 23 in both clamping ends are started. The second motors 23 drive the second lead screw 22 to rotate. The second lead screw 22 is connected to the slide block 21 by a thread, and the guide rod 20 is connected to the fixed frame 16 by a thread. The sliding connection increases the distance between the abutment frame 18 and the fixed frame 16, and the distance between the two abutment frames 18 at the two clamping ends gradually shortens. During this process, both ends of the glass plate 1 can enter the grooves 19 of the abutment frame 18 respectively. A pressure sensor is provided in the groove 19 of the abutment frame 18. When the pressure applied by the glass plate 1 to the pressure sensor reaches the target pressure value, both second motors 23 stop rotating at the same time. At this time, the glass plate 1 is clamped by the two abutment frames 18. Subsequently, the glass plate 1 can be flipped by the rotating unit.

[0025] Furthermore, the rotating unit includes a fixed frame 24, which is located on the outside of the movable frame 10. A third motor 25 is mounted on the fixed frame 24, and the output end of the third motor 25 is connected to the sleeve 17.

[0026] When controlling the rotation of the glass plate 1 between the two abutment frames 18, the first motor 15 needs to be started first. The first motor 15 drives the first lead screw 14 to rotate, causing the movable frame 10 to move upward, thus raising the height of the glass plate 1 and maintaining a sufficient gap between the glass plate 1 and the conveyor belt 2. Then, the third motor 25 is started. The third motor 25 drives the fixed frame 16 connected to the sleeve 17 to rotate through the sleeve 17. Since the two fixed frames 16 are connected by the connecting rod 4, and since the glass plate 1 is located inside the two abutment frames 18, the third motor 25 can simultaneously drive the two abutment frames 18 to rotate 180°, and also rotate the glass plate 1 180°. After the glass plate 1 is flipped, the first motor 15 is started, and the output end of the first motor 15 is flipped, which drives the first lead screw 14 to reverse, causing the movable frame 10 to move downward and the two abutment frames 18 to move downward. During the descent, the conveyor belt 2 will abut against the connecting rod 4, and the connecting rod 4 will always be above the conveyor belt 2 by squeezing the spring 8. The two abutment frames 18 can move downward normally. When the glass plate 1 is placed on the conveyor belt 2, the first motor 15 stops working, and then the two second motors 23 are controlled to rotate in opposite directions, so that the two ends of the glass plate 1 are moved out of the grooves 19 of the abutment frames 18. Then the conveyor belt 2 starts to continue transporting the flipped glass plate 1.

[0027] At the same time, the movable frame 10 needs to be controlled to move upward, so that the two abutment frames 18 move upward. Then, the two abutment frames 18 are controlled to rotate in opposite directions by the third motor 25, so that the position of the connecting rod 4 is reset. This ensures that when the glass plate 1 comes into contact with the contact sensor 9, the glass plate 1 is just between the two abutment frames 18, thus enabling the clamping of the glass plate 1 and subsequent flipping operations.

[0028] Furthermore, the opening end of the groove 19 in the abutment frame 18 is set in a trumpet shape to facilitate the entry of both ends of the glass plate 1 into the groove 19.

[0029] The height of the groove 19 is greater than the thickness of the glass plate 1, approximately 1.3 times the thickness of the glass plate 1.

[0030] The following steps are included when flipping glass plate 1: 1. Conveyor belt 2 transports glass plate 1 until glass plate 1 comes into contact with contact sensor 9, at which point conveyor belt 2 stops moving; 2. The two abutting frames 18 are brought close to each other, so that both ends of the glass plate 1 can enter the grooves 19 of the two abutting frames 18; 3. Next, control the abutment frame 18 to move upward, and drive the glass plate 1 to move upward. When the glass plate 1 moves upward to a certain height, control the two abutment frames 18 and the glass plate 1 to rotate 180°. 4. Then control the two abutment frames 18 and the glass plate 1 to move downwards. When the glass plate 1 is placed on the conveyor belt 2, the conveyor belt 2 continues to start and convey the glass plate 1 out. 5. The two abutment frames 18 continue to move upward, and then the two abutment frames 18 are controlled to rotate 180° in opposite directions, so that when the subsequent glass plate 1 comes into contact with the contact sensor 9, the glass plate 1 can also be located between the two abutment frames 18.

[0031] The first motor 15, the second motor 23, and the third motor 25 can all be equipped with speed reducers. The equipment is controlled by a PLC system, and the start and stop of each motor, as well as the start and stop of the conveyor belt 2, are controlled by various sensors.

[0032] By controlling the moving speed of the conveyor belt 2, the glass plates 1 transported on the conveyor belt 2 can be flipped in sequence.

[0033] Link 4 is made of steel plate with anti-torsion reinforcing ribs on the surface to ensure that the two abutment frames can maintain basic synchronous rotation.

[0034] This flipping device can also be used to flip various types of glass, not just photovoltaic glass. However, regular maintenance is required to ensure the normal operation of the equipment.

[0035] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
