When the sealing head 4 moves to a high position with the piston rod 3, its blocking portion 41 is sealed with the glue outlet 52. When the sealing head 4 moves to a low position with the piston rod 3, a glue outlet gap is formed between the blocking portion 41 and the glue outlet 52. The vertically extending dispensing head 16 is rotatably mounted on a substrate 18 horizontally arranged below the dispensing valve dispensing block 2 through a bearing 17. A motor 20 is installed on the upper surface of the substrate 18 and located on one side of the dispensing valve. A driven gear 191 is sleeved on the outer side of the dispensing head 16 and located below the substrate 18. A driving gear 192 meshing with the driven gear 191 is drivingly connected to the output shaft of the motor 20.

[0019] The dispensing mechanism is integrally mounted on the three-axis driving mechanism to perform dispensing operations on the edges of the rectangular photovoltaic glass;

[0020] The photovoltaic glass to be glued is placed horizontally under the glue dispensing head of the glue dispensing mechanism. Under the action of the three-axis driving mechanism, the glue dispensing head is first moved to a suitable height at a corner of the photovoltaic glass and the rectangular glue dispensing port of the glue dispensing head is parallel to one side of the photovoltaic glass. Then the three-axis driving mechanism drives the glue dispensing head to move along the length direction of the other side of the photovoltaic glass and opens the glue dispensing gap of the glue dispensing valve while moving, thereby realizing the glue dispensing operation at the edge of one side of the photovoltaic glass.

[0021] During the dispensing operation, the sealing head is driven downward by the piston rod to form a glue outlet gap between the sealing part and the glue outlet. The glue liquid entering from the glue inlet passes through the glue inlet flow channel and the glue outlet flow channel in turn and is then discharged outward through the glue outlet pipe.

[0022] The motor 20 is mounted on the upper surface of the base plate 18 via a support seat 9 . The lower end of the output shaft of the motor 20 is connected to a rotating shaft 11 via a coupling 10 . The lower end of the rotating shaft 11 passes through the base plate 18 and is equipped with the driving gear 192 .

A glue feeding hole 132 is provided on the upper surface of the mounting block 13. The upper end of the glue feeding hole 132, whose lower end is connected to the mounting groove 131, is connected to the glue outlet 52. The sealing portion 41 of the sealing head 4 is embedded in the glue feeding hole 132 and is gap-matched with the inner wall of the glue feeding hole 132.

[0024] The mounting block 13 is sealedly connected to the dispensing valve glue feeding block 2 via a sealing ring 21 disposed outside the glue feeding hole 132 .

[0030] The driven gear meshing with the driving gear is driven by the rotation of the motor to rotate, so that the dispensing head rotates 90°. During this process, the dispensing gap of the dispensing valve is closed;

[0031] When the dispensing head needs to stop dispensing glue during the reversing operation, the piston rod drives the sealing head to move up. When the sealing head moves to the high position with the piston rod, its sealing part cooperates with the glue outlet to prevent the glue from continuing to flow out, thereby achieving instantaneous cutoff of the glue without glue leakage, ensuring the subsequent dispensing quality.

[0032] Then, the three-axis driving mechanism drives the dispensing head to move along the length direction of the other side of the photovoltaic glass that is perpendicular to the side where the dispensing has been completed, and opens the dispensing gap of the dispensing valve while moving, thereby realizing the dispensing operation on the edge of the other side of the photovoltaic glass;

[0033] In this reciprocating process, continuous dispensing operation is achieved on the edges of the photovoltaic glass, improving the continuity and efficiency of dispensing.

[0034] The motor 20 is mounted on the upper surface of the base plate 18 via a support seat 9 . The lower end of the output shaft of the motor 20 is connected to a rotating shaft 11 via a coupling 10 . The lower end of the rotating shaft 11 passes through the base plate 18 and is equipped with the driving gear 192 .

[0035] A mounting block 13 is arranged between the dispensing valve glue feeding block 2 and the substrate 18. The upper part of the dispensing head 16 is embedded in a mounting groove 131 provided on the lower surface of the mounting block 13 and is rotatably sealed with the inner wall of the mounting groove 131 through at least two rotating sealing rings 14. A glue feeding hole 132 is provided on the upper surface of the mounting block 13. The upper end of the glue feeding hole 132, whose lower end is connected to the mounting groove 131, is connected to the glue outlet 52.

[0036] The mounting block 13 is sealedly connected to the dispensing valve glue feeding block 2 via a sealing ring 21 disposed outside the glue feeding hole 132 .

[0037] The rotating shaft 11 and the base plate 18 are rotatably connected via a bearing.

[0038] A sensing sheet 121 which can rotate with the rotating shaft 11 is installed on the rotating shaft 11 , and a sensor 122 which cooperates with the sensing sheet 121 is installed on the supporting seat 9 .

[0039] The diameter ratio of the driven gear 191 to the driving gear 192 is 2, and two sensors 122 are provided and are spaced 180° apart in the circumferential direction.

[0040] A sealing ring 22 is installed at the lower end of the glue outlet channel 62 . The inner diameter of the sealing ring 22 is smaller than the outer diameter of the blocking portion 41 .

[0041] A PEEK ring 23 is disposed below the sealing ring 22 and outside the blocking portion 41 . The inner wall of the PEEK ring 23 is in sliding contact with the outer surface of the blocking portion 41 .

[0042] The working principle of the utility model is as follows:

[0043] The dispensing mechanism is integrally mounted on the three-axis driving mechanism to perform dispensing operations on the edges of the rectangular photovoltaic glass;

[0044] The photovoltaic glass to be glued is placed horizontally under the glue dispensing head of the glue dispensing mechanism. Under the action of the three-axis driving mechanism, the glue dispensing head is first moved to a suitable height at a corner of the photovoltaic glass and the rectangular glue dispensing port of the glue dispensing head is parallel to one side of the photovoltaic glass. Then the three-axis driving mechanism drives the glue dispensing head to move along the length direction of the other side of the photovoltaic glass and opens the glue dispensing gap of the glue dispensing valve while moving, thereby realizing the glue dispensing operation at the edge of one side of the photovoltaic glass.

[0045] Next, the driven gear meshing with the driving gear is driven by the rotation of the motor to rotate, so that the dispensing head rotates 90°. During this process, the dispensing gap of the dispensing valve is closed.

[0046] Then, the three-axis driving mechanism drives the dispensing head to move along the length direction of the other side of the photovoltaic glass that is perpendicular to the side where the dispensing has been completed, and opens the dispensing gap of the dispensing valve while moving, thereby realizing the dispensing operation on the edge of the other side of the photovoltaic glass;

[0047] In this reciprocating manner, continuous dispensing operation is achieved on the edges of the photovoltaic glass, improving the continuity and efficiency of dispensing;

[0048] When dispensing is required, the sealing head is driven downward by the piston rod to form a gap between the sealing part and the glue outlet. The glue entering from the glue inlet passes through the glue inlet flow channel and the glue outlet flow channel in turn and then is discharged out through the glue outlet pipe.

[0049] When the dispensing head needs to be reversed and the dispensing of glue needs to be stopped, the piston rod is used to drive the sealing head to move up. When the sealing head moves to a high position with the piston rod, its sealing part cooperates with the glue outlet to prevent the glue therein from continuing to flow out, thereby achieving instantaneous cut-off of the glue without glue leakage, thereby ensuring the subsequent dispensing quality.

[0050] When the above-mentioned reversible photovoltaic glass dispensing structure is used, while realizing the switching between continuous glue supply and stop glue supply to the dispensing head, the dispensing direction can be quickly switched by rotating the dispensing head, thereby improving the continuity and efficiency of dispensing.

[0051] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
