Description

Technical Field

[0001] This utility model relates to the field of laminating technology, specifically to a multi-station rotary laminating machine for photovoltaic panel processing. Background Technology

[0002] A solar laminator, also known as a solar cell module laminator or photovoltaic module laminator, is a mechanical device that presses together layers of materials, including glass, EVA, connected individual cells, and a backsheet. Solar laminators are used in solar photovoltaic production lines. The principle involves applying pressure to the surfaces of each layer and pressing them together tightly under heating. Existing photovoltaic module laminators generally use linear transport laminators, processing and assembling the components sequentially before entering a vacuum chamber for lamination. Linear transport suffers from drawbacks such as slippage, inaccurate positioning, and excessively long threads. Furthermore, the linear circulating transport structure cannot accommodate a ejector pin mechanism, causing the workpiece to come into immediate contact with the laminator during transport. This prolonged heating time and uneven heating can lead to warping. Existing vacuum chambers are also designed for linear transport laminators. To accommodate improved rotary laminators, the vacuum chamber also needs modification. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a multi-station rotary laminator for photovoltaic panel processing, which solves the problems of slippage, inaccurate positioning, and excessively long threads in linear transportation mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-station rotary laminator for photovoltaic panel processing, comprising a frame, a fixed frame inside the frame, a central shaft fixedly installed at the center of the frame, a rotary bearing sleeved on the outer surface of the central shaft, a plurality of limiting pins inserted inside the rotary bearing, a bearing frame threadedly fixed on the outer surface of the limiting pins, four cams fixedly installed on the lower side of the bearing frame, the right side of the rotary bearing meshing with a drive reduction motor, a cam disk provided on the upper outer surface, a second fixed frame fixedly installed inside the frame above the first bearing frame, a pressing cylinder fixedly installed on the lower side of the second fixed frame, a vacuum chamber cover installed at the output end of the pressing cylinder, a lifting cylinder installed at the bottom of the frame, and a vacuum chamber cover provided on the upper side of the first fixed frame.

[0005] Preferably, a number of heaters are provided on the lower side of the inner layer of the support frame, and a number of capsule ejectors are provided on the upper side of the support frame, with the capsule ejectors protruding from the outer surface of the support frame.

[0006] Preferably, the first-layer support frame is divided into four equal stations: a material feeding / discharging station, a lamination station, a curing station, and a cooling station.

[0007] Preferably, the lower right corner of the first-layer support frame is the lamination station. The first-layer fixed frame, the lower cover of the vacuum chamber, the first-layer support frame, the upper cover of the vacuum chamber, and the second-layer fixed frame are respectively arranged in four sets. The first-layer fixed frame, the lower cover of the vacuum chamber, the first-layer support frame, the upper cover of the vacuum chamber, and the second-layer fixed frame form a sealed vacuum chamber. There are also three vacuum chambers located on the upper side of the second-layer fixed frame.

[0008] Preferably, the cam disk has four trapezoidal grooves inside, and the four cams correspond to the four trapezoidal grooves.

[0009] Preferably, the limiting pin adopts a segmented thread design, with the lower end of the limiting pin in active contact with the interior of the rotary bearing, and the upper end of the limiting pin connected to the internal thread of the first-layer support frame.

[0010] Preferably, the lower cover of the vacuum chamber matches the size of the upper cover of the vacuum chamber.

[0011] Preferably, the capsule ejector pin is made of a high-temperature resistant material.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This photovoltaic panel processing multi-station rotary laminator divides a single-layer support frame into four equal stations. Due to the prototype structure design of the support frame, a rotary working mode is formed. This design can effectively avoid the problem of inaccurate positioning caused by material displacement during linear conveyor belt transportation, and avoid the increased energy consumption due to excessive heat dissipation caused by large equipment footprint. The rotary laminator saves energy.

[0014] 2. This photovoltaic panel processing multi-station rotary laminator forms a sealed, independent vacuum chamber through a first-layer fixed frame, a lower cover of the vacuum chamber, a first-layer support frame, an upper cover of the vacuum chamber, and a second-layer fixed frame. Three additional vacuum chambers are located on the upper side of the second-layer fixed frame. Because the rotary laminator replaces the original conveyor belt with a rotary feed and discharge mechanism, it reduces the height occupied by the conveyor belt, freeing up considerable vertical space. While improving the vacuum chambers in conjunction with the rotary laminator, we utilized the saved space to increase the number of vacuum chambers, significantly improving the laminator's working efficiency.

[0015] 3. This multi-station rotary laminator for photovoltaic panel processing features a rotary bearing mounted on the outer surface of a central shaft. A cam disc is mounted on the upper outer surface of the rotary bearing, and several limit pins are inserted inside the bearing. A support frame is threaded onto the outer surface of each limit pin. Four cams are fixedly installed on the lower side of the support frame. By cleverly utilizing the cam structure, as the four cams rotate past the grooves in the cam disc, the support frame descends. This, in conjunction with a lifting cylinder, ensures a tight fit between the support frame and the lower cover of the vacuum chamber. Simultaneously, a pressing cylinder pushes down the upper cover of the vacuum chamber, forming an independent vacuum chamber. The cam disc structure facilitates pre-sinking, making this process more convenient and time-saving compared to conventional methods.

[0016] 4. This photovoltaic panel processing multi-station rotary laminator has several sets of heaters installed on the lower side of the inner side of the first-layer support frame, and several capsule ejector pins installed on the upper side of the first-layer support frame. The capsule ejector pins protrude from the outer surface of the first-layer support frame. The clever placement of the capsule ejector pins ensures that the workpiece does not come into direct contact with the heating plate during transportation without heating and lamination, thus avoiding uneven heating and edge warping during transportation. The use of capsule ejector pins in conjunction with the pressurization of the vacuum chamber achieves a physical ejector pin structure, which also effectively avoids the problem of large space occupation caused by the complex structure of mechanical ejector pins.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Referring to Figures 1-3, when using this utility model, a fixed frame 2 is fixedly installed inside the frame 1, a central shaft 4 is fixedly installed in the center of the frame 1, a rotary bearing 14 is sleeved on the outer surface of the central shaft 4, a cam disk 5 is provided on the upper outer surface of the rotary bearing 14, several limiting pins 12 are inserted inside the rotary bearing 14, a layer of bearing frame 3 is threaded on the outer surface of the limiting pins 12, four cams are fixedly installed on the lower side of the first layer of bearing frame 3, the right side of the rotary bearing 14 meshes with the drive reduction motor 6, a second layer of fixed frame 7 is fixedly installed inside the frame 1 above the first layer of bearing frame 3, a pressing cylinder 8 is fixedly installed on the lower side of the second layer of fixed frame 7, a vacuum chamber cover 9 is installed at the output end of the pressing cylinder 8, a lifting cylinder 11 is installed at the bottom inside the frame 1, and a vacuum chamber cover 10 is provided on the upper side of the first layer of fixed frame 2.

[0026] Working Principle: When using this photovoltaic panel processing multi-station rotary laminator, a synchronous conveyor belt transports the workpiece to the upper left side of the first-layer support frame 3. The lower outer surface of the workpiece is in contact with the upper outer surface of several capsule ejector pins 16. The capsule ejector pins 16 prevent the workpiece from contacting the heating plate at the beginning. When the equipment starts, the drive reduction motor 6 rotates, which drives the rotating bearing 14 meshing with it to rotate. The rotation of the rotating bearing 14 drives several limit pins 12 and the first-layer support frame 3 to rotate together. The rotation of the first-layer support frame 3 drives four cams fixedly installed on the lower side of the first-layer support frame 3 to rotate along the outer surface of the cam disk 5. When the cam rotates to the groove inside the cam disk 5, the equipment senses and stops. The first-layer support frame 3 pre-descends due to the cam rotating to the groove inside the cam disk 5. Then, in conjunction with the lifting cylinder 11, the lower cover 10 of the vacuum chamber is tightly attached to the lower outer surface of the pre-descended first-layer support frame 3. Then, the pressing cylinder 8 drives the upper cover 9 of the vacuum chamber to descend. The workpiece is pressed tightly against the outer surface of the upper layer of the support frame 3 to form a vacuum chamber. Then, the upper cover 9 of the vacuum chamber applies downward pressure, while the lower cover 10 of the vacuum chamber applies upward suction. The capsule ejector pin 16 is also pressed into the inner surface of the support frame 3 under the suction and pressure of the vacuum chamber, so that the workpiece is tightly attached to the outer surface of the support frame. The heater 15 inside the support frame 3 works, and in conjunction with the high-pressure environment of the vacuum chamber, the workpiece to be processed is sealed in the independent vacuum chamber for lamination. After the process is completed, the upper cover 9 and the lower cover 10 of the vacuum chamber are reset, the equipment is activated by induction, and continues to rotate. When the cam on the lower side of the support frame 3 moves out of the arc-shaped groove in the cam disk 5 under rotation, the support frame 3 is lifted up and moved to the next station for curing. Then it continues to rotate. When the cam rotates to the next groove inside the cam disk 5, the operation is repeated for cooling. Then it continues to rotate to the feeding station for unloading.

[0027] Compared with related technologies, the multi-station rotary laminator for photovoltaic panel processing provided by this utility model has the following beneficial effects: compared with the traditional linear laminator, the rotary laminator has better working efficiency, and while greatly improving working efficiency, it shortens the transportation distance between stations to ensure the quality of the workpiece.
