Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic components, in particular to a pre-pressing mechanism of a photovoltaic component. Background Art

[0002] With the rapid development of the photovoltaic power generation industry, the requirements for efficiency and quality of photovoltaic module production equipment are becoming increasingly stringent. Laminators, as key equipment in photovoltaic module production, are primarily used to laminate solar cells, EVA film, glass, and backsheet materials. Through heating, vacuuming, and pressurizing processes, the layers are tightly bonded to form stable and durable photovoltaic modules.

[0003] However, during the current lamination process, defects such as shifting or bubbles often occur in photovoltaic modules due to limitations in material properties and operating conditions. These defects not only affect the module's sealing effectiveness but can also reduce the module's power generation efficiency and lifespan during use. While traditional clamping and preloading mechanisms can somewhat suppress module shifting, they fail to provide uniform preload across all parts of the module. This can easily cause slight shifts during high-temperature lamination, leading to bubble formation and poor preloading effectiveness. Utility Model Content

[0032] See also Figures 1 to 4As shown, in this embodiment, a pre-pressing mechanism of a photovoltaic component includes a pre-pressing platform 1, a first pre-pressing component 2, a second pre-pressing component 3, a flexible pre-pressing component 4 and an induction component 5, wherein: the pre-pressing platform 1 has a bearing surface 10 for bearing the photovoltaic component 100 to be pre-pressed; the first pre-pressing component 2 is located directly above the bearing surface 10, the first pre-pressing component 2 includes a mounting frame 20, a first driving member 21 and a lifting member 22, the mounting frame 20 is mounted on the pre-pressing platform 1, the lifting member 22 is liftably arranged on the mounting frame 20, the driving end of the first driving member 21 is connected to the lifting member 22, and the first driving member 21 is configured to drive the lifting member 22 to a high position or a low position; the second pre-pressing component 3 is mounted on the lifting member 22, the second pre-pressing component 3 includes a second driving member 30 and a lifting member 22 along the first direction ( Figure 1 The first traverse member 31 and the second traverse member 32 are spaced apart in the X direction in the middle. The flexible pre-pressing assembly 4 includes a first flexible pre-pressing member 40 and a second flexible pre-pressing member 41. The first flexible pre-pressing member 40 is mounted on the first traverse member 31, and the second flexible pre-pressing member 41 is mounted on the second traverse member 32. The first flexible pre-pressing member 40 and the second flexible pre-pressing member 41 are moved along the second direction ( Figure 1 The driving end of the second driving member 30 is connected to the first transverse member 31 and / or the second transverse member 32. The second driving member 30 is configured to drive the first transverse member 31 and the second transverse member 32 to move closer to or away from each other when the lifting member 22 is in a low position, so as to drive the first flexible pre-compression member 40 and the second flexible pre-compression member 41 to move, thereby pre-compressing the photovoltaic component 100 on the bearing surface 10; the sensing component 5 is configured to detect whether the lifting member 22 moves to a low position, and transmit the detection information to the first driving member 21.

[0033] It can be seen that through the cooperation of the first pre-stressing component 2, the second pre-stressing component 3 and the sensing component 5, the first driving member 21 drives the lifting member 22 to a low position, and the second driving member 30 drives the first transverse member 31 and the second transverse member 32 to move closer to or away from each other when the lifting member 22 is in a low position, driving the first flexible pre-stressing member 40 and the second flexible pre-stressing member 41 to move, and then pre-stressing the photovoltaic component 100 on the bearing surface 10. The sensing component 5 detects whether the lifting member 22 moves to a low position, and transmits the detection information to the first driving member 21, thereby providing uniform pre-stress to each part of the photovoltaic component 100, without generating bubbles, and having a good pre-stressing effect.

[0034] Specifically, the first driving member 21 is a driving cylinder, and the second driving member 30 is two rodless cylinders, and the driving ends of the two rodless cylinders are respectively connected to the first transverse member 31 and the second transverse member 32.

[0035] As an embodiment, the supporting surface 10 is a square surface that matches the photovoltaic component 100 to be pre-pressed, and buffer components 6 are evenly distributed at the four corners of the supporting surface 10. The buffer components 6 are configured to buffer the movement of the lifting component 22 when the lifting component 22 descends to a low position to avoid hard contact between the lifting component 22 and the photovoltaic component 100 to be pre-pressed.

[0036] As an embodiment, each buffer assembly 6 includes a guide shaft 60 and a buffer spring 61. The corresponding guide shaft 60 is provided with a guide groove 23 on the lifting member 22. Each buffer spring 61 is sleeved on the corresponding guide shaft 60. The first end of each buffer spring 61 is installed on the bearing surface 10. The second end of the buffer spring 61 is set upward and a buffer pad 62 is installed on the end. When the lifting member 22 descends to the low position, each guide shaft 60 is passed through the corresponding guide groove 23, the lifting member 22 rests on the buffer pad 62 and overcomes the elastic force of the buffer spring 61 to move downward.

[0037] It can be seen that buffer components 6 are provided at the four corners of the bearing surface 10, which effectively avoids the hard contact between the lifting member 22 and the photovoltaic component 100 to be pre-pressed, protects the photovoltaic component 100 to be pre-pressed, and at the same time, through the cooperation of the guide shaft 60 and the buffer spring 61, while achieving buffering of the lifting member 22, it can also have a guiding function.

[0038] As an embodiment, the induction component 5 includes an induction generator 50 and an induction receiver 51. The induction generator 50 is installed on the pre-pressing table 1, and the induction receiver 51 is installed on the lifting member 22. The induction generator 50 is configured to transmit a signal to the lifting member 22, and the induction receiver 51 is configured to receive the signal emitted by the induction generator 50 and transmit the stop signal to the first driving member 21; when the lifting member 22 is in a high position, the induction receiver 51 cannot receive the signal emitted by the induction generator 50; when the lifting member 22 drops to a low position, the induction receiver 51 receives the signal emitted by the induction generator 50.

[0039] It can be seen that the automatic control of the lifting member 22 is achieved through the cooperation of the induction generator 50 and the induction receiver 51.

[0040] As an embodiment, the pre-pressing mechanism of the photovoltaic module further includes a transporting assembly 7 , which is configured to pick up the pre-pressed photovoltaic module 100 and transport it to a subsequent process.

[0041] As an embodiment, the transport component 7 includes a manipulator 70 and a Bernoulli suction cup 71. The driving end of the manipulator 70 is connected to the first end of the Bernoulli suction cup 71. The second end of the Bernoulli suction cup 71 serves as an adsorption end. The adsorption end of the Bernoulli suction cup 71 has several adsorption areas based on the Bernoulli effect. The Bernoulli suction cup 71 is configured to adsorb the pre-pressed photovoltaic component 100, and cooperate with the manipulator 70 to pick up the pre-pressed photovoltaic component 100 and transport it to the subsequent process.

[0042] It can be seen that the pre-pressed photovoltaic assembly 100 is transported by using the manipulator 70 and the Bernoulli suction cup 71 , thereby achieving non-contact transport and avoiding damage to the photovoltaic assembly 100 .

[0043] It should be noted that the principle of negative pressure generated by the Bernoulli effect is that the Bernoulli suction cup 71 is provided with an air inlet, an air cavity and an air outlet. The gas enters the air cavity from the air inlet of the Bernoulli suction cup 71 and flows out from the air outlet. The flow rate of the outflowing gas is large, which will generate a uniform and thin strong airflow at the adsorption end. At this time, the gas flow rate on the upper surface of the sheet is greater than the gas flow rate on its lower part. According to the principle that the faster the fluid speed, the lower the pressure, a pressure difference will be generated on the upper and lower sides of the photovoltaic component 100, thereby forming an upward lifting force at the bottom of the photovoltaic component 100, so that the pre-pressed photovoltaic component 100 is adsorbed in the adsorption area.

[0044] As an embodiment, a detection component 8 is provided on one side of the pre-pressing platform 1 , and the detection component 8 is configured to perform detection on the pre-pressed photovoltaic component 100 .

[0045] Specifically, the detection component 8 includes a CDD industrial camera and a backlight source. The CDD industrial camera is installed on the mounting frame 20, and the backlight source is set on the pre-pressing platform 1. Through the cooperation of the CDD industrial camera and the backlight source, the pre-pressed photovoltaic component 100 located on the pre-pressing platform 1 is photographed and detected.

[0046] As an embodiment, the first flexible pre-pressing member 40 and the second flexible pre-pressing member 41 may be configured as flexible pre-pressing rollers or flexible pre-pressing plates.

[0047] It should be noted that the first flexible pre-pressing member 40 and the second flexible pre-pressing member 41 use flexible pre-pressing rollers. During pre-pressing, a rotating driving member can be set at the end of the flexible pre-pressing roller to drive the flexible pre-pressing roller to roll, and the first flexible pre-pressing member 40 and the second flexible pre-pressing member 41 can be pre-pressed back and forth multiple times, and move horizontally while rolling until all positions of the photovoltaic component 100 are subjected to uniform pre-pressure. After the pre-pressing is completed, the bonding effect between the layers of the photovoltaic component 100 is good.

[0048] When the prestressing mechanism of the above-mentioned photovoltaic module is prestressed: the first driving member 21 drives the lifting member 22 to the low position, each guide shaft 60 is inserted into the corresponding guide groove 23, and at the same time the lifting member 22 rests on the buffer pad 62 and overcomes the elastic force of the buffer spring 61 to move downward. After reaching the position, the induction receiver 51 receives the signal sent by the induction generator 50 and transmits the stop signal to the first driving member 21, and the first driving member 21 stops working; the second driving member 30 drives the first transverse member 31 and the second transverse member 32 to move closer to or away from each other when the lifting member 22 is in the low position, so as to drive the first flexible prestressing member 40 and the second flexible prestressing member 41 moves, and then performs reciprocating pre-stressing on the photovoltaic component 100 on the bearing surface 10, so that each position of the photovoltaic component 100 is subjected to stable pre-stressing; after the pre-stressing is completed, the first driving member 21 drives the lifting member 22 to the high position, and the CDD industrial camera cooperates with the backlight source to perform photo inspection on the pre-stressed photovoltaic component 100 located on the pre-stressing platform 1; after the inspection is qualified, the robot 70 drives the Bernoulli suction cup 71 to move to the top of the pre-stressed photovoltaic component 100, and the Bernoulli suction cup 71 absorbs the pre-stressed photovoltaic component 100, and cooperates with the robot 70 to pick up the pre-stressed photovoltaic component 100 and transport it to the subsequent process.

[0049] The above embodiments merely illustrate the basic principles and features of the present invention. The present invention is not limited to the above embodiments. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention.
