Technical Field

[0001] The invention relates to the technical field of laminators, in particular to a multi-station rotary laminator for photovoltaic panel processing. Background Art

[0002] Solar laminator, often called laminator, also called solar cell module laminator, can also be called photovoltaic module laminator; usually refers to mechanical equipment that presses glass, EVA, connected single cells, EVA, backplane, these layers of materials together; solar laminator is used in solar cell photovoltaic production line; its principle is to apply a certain pressure on the surface of each layer of material, and press these materials tightly together under heating. Existing photovoltaic module laminators generally use linear transport laminators, which are processed and assembled in sequence and then enter the vacuum chamber for lamination. Because linear transport has the disadvantages of slipping during transport, inaccurate positioning accuracy, and too long threads, and the linear circulating structure transport cannot be equipped with a pin mechanism, which will cause the workpiece to contact the laminator at the first time of transport. Long heating time and uneven heating will cause warping. The existing vacuum chamber is also a laminator that cooperates with linear transport. In order to cooperate with the improved rotary laminator, its vacuum chamber also needs to be improved. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a multi-station rotary laminator for photovoltaic panel processing to solve the problems of linear transportation mentioned in the above background technology, such as slippage, inaccurate positioning accuracy, and excessively long threads.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a multi-station rotary laminator for processing photovoltaic panels, comprising a frame, a layer of fixed frame fixedly installed inside the frame, a central axis fixedly installed at the center of the frame, a rotating bearing sleeved on the outer surface of the central axis, a plurality of limiting nails inserted inside the rotating bearing, a layer of supporting frame threadedly fixed on the outer surface of the limiting nails, four cams fixedly installed on the lower side of the layer of supporting frame, the right side of the rotating bearing is engaged with a driving reduction motor, a cam disk is provided on the upper outer surface, a second layer of fixed frame is fixedly installed inside the frame above the first layer of supporting frame, a downward pressure cylinder is fixedly installed on the lower side of the second layer of fixed frame, a vacuum chamber upper cover is installed on the output end of the downward pressure cylinder, a lifting cylinder is installed at the bottom of the frame body, and a vacuum chamber lower cover is provided on the upper side of the first layer of fixed frame.

[0005] Preferably, a plurality of groups of heaters are arranged on the lower side of the inner part of the first layer of the carrier frame, and a plurality of capsule ejectors are arranged on the upper side of the first layer of the carrier frame, and the plurality of capsule ejectors protrude from the outer surface of the first layer of the carrier frame.

[0006] Preferably, the first layer of the carrier is equally divided into four stations, namely, a material loading and unloading station, a laminating station, a curing station, and a cooling station. Preferably, the lower right corner of the first-layer carrier is a lamination station, and the first-layer fixed frame, the vacuum chamber lower cover, the first-layer carrier, the vacuum chamber upper cover and the second-layer fixed frame are respectively provided with four groups, and the first-layer fixed frame, the vacuum chamber lower cover, the first-layer carrier, the vacuum chamber upper cover and the second-layer fixed frame form a closed vacuum chamber, and there are three such vacuum chambers located on the upper side of the second-layer fixed frame.

[0007] Preferably, the cam plate is provided with four trapezoidal grooves inside, and the four cams correspond to the four trapezoidal grooves. Preferably, the limiting pin adopts a segment thread design, the lower end of the limiting pin is movably fitted with the inside of the rotating bearing, and the upper end of the limiting pin is connected with the inner thread of the first layer of the supporting frame. Preferably, the size of the vacuum chamber lower cover matches that of the vacuum chamber upper cover.

[0008] Preferably, the capsule ejector pin is made of high temperature resistant material.

[0009] Compared with the prior art, the present invention has the following beneficial effects: 1. The multi-station rotary laminator for processing photovoltaic panels divides a layer of carrier into four equal stations. Since the carrier is designed as a prototype structure, a rotary working mode is formed. This design can well avoid the problem of inaccurate positioning accuracy caused by material displacement during the transportation process of the linear conveyor belt, avoid the equipment occupying too much area and increase energy consumption after heat dissipation. The rotary laminator saves energy.

[0010] 2. The multi-station rotary laminator for processing photovoltaic panels forms a closed independent vacuum chamber through a first-layer fixed frame, a vacuum chamber lower cover, a first-layer bearing frame, a vacuum chamber upper cover and a second-layer fixed frame, and there are three vacuum chambers on the upper side of the second-layer fixed frame. Since the rotary laminator realizes rotary feeding and discharging to replace the original conveyor belt, the height occupied by the upper and lower sides of the conveyor belt is reduced, thereby freeing up a lot of upper and lower space. While cooperating with the rotary laminator to improve the vacuum chamber, we utilize the saved space, increase the number of vacuum chambers, and greatly improve the working efficiency of the laminator.

[0011] 3. The photovoltaic panel processing multi-station rotary laminator has a rotary bearing sleeved on the outer surface of the central shaft, a cam disc is arranged on the upper outer surface of the rotary bearing, a number of limit pins are inserted inside the rotary bearing, a layer of carrier is fixed by threads on the outer surface of the limit pins, and four cams are fixedly installed on the lower side of the layer of carrier. The cam structure is cleverly utilized. When the four cams on the lower side of the layer of carrier rotate through the groove position in the convex disc, the layer of carrier will descend, and cooperate with the lifting cylinder to make it fit tightly with the lower cover of the vacuum chamber, and cooperate with the pressing cylinder to drive the upper cover of the vacuum chamber to be pressed down to form an independent vacuum chamber, and use the cam disc structure for pre-sinking. Compared with the ordinary method, this is more convenient and saves processing time.

[0012] 4. The multi-station rotary laminator for processing photovoltaic panels has several groups of heaters arranged on the lower side of a layer of carrier frame, and several capsule ejectors arranged on the upper side of a layer of carrier frame. Several capsule ejectors protrude from the outer surface of one layer of carrier frame. The capsule ejectors are cleverly arranged so that the workpiece will not come into direct contact with the heating plate during transportation without heating and lamination, thereby avoiding the situation of warping caused by uneven heating during transportation. The capsule ejectors are used in conjunction with the pressurization of the vacuum chamber to realize the physical ejector structure, which also avoids the problem of large space occupied by the complex structure of the mechanical ejector.

[0017] Working principle: when using the multi-station rotary laminator for processing photovoltaic panels, a synchronous conveyor belt is used to convey the processed workpiece to the upper left side of a layer of carrier frame 3, and the lower outer surface of the workpiece is movably fitted with the upper outer surfaces of several capsule ejectors 16. The capsule ejectors 16 prevent the workpiece from contacting the heating plate at the beginning. The equipment is started, and the reduction motor 6 is driven to rotate and drive the rotating bearing 14 engaged therewith to rotate. The rotation of the rotating bearing 14 drives several limit pins 12 and a layer of carrier frame 3 to rotate together. The rotation of a layer of carrier frame 3 drives four cams fixedly installed on the lower side of a layer of carrier 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 a pause, and a layer of carrier frame 3 is pre-descended due to the cam rotating to the groove inside the cam disk 5, and then the lifting cylinder 11 is cooperated to make the lower cover 10 of the vacuum chamber fit tightly with the lower outer surface of the pre-descended layer of carrier frame 3, and then the downward pressure cylinder 8 drives the upper cover 9 of the vacuum chamber to go down The workpiece is pressed into the outer surface of the upper side of a layer of carrier frame 3 to form a vacuum chamber, and then the upper cover 9 of the vacuum chamber applies downward pressure, and the lower cover 10 of the vacuum chamber applies suction upward. The capsule ejector pin 16 is also pressed into the inner part of a layer of carrier frame 3 under the suction and pressure of the vacuum chamber, so that the workpiece is tightly fitted with the outer surface of the layer of carrier frame. The heater 15 inside the layer of carrier frame 3 works, and cooperates with the high-pressure environment of the vacuum chamber to seal the workpiece to be processed in the inner part of an independent vacuum chamber for lamination. After completion, the upper cover 9 of the vacuum chamber and the lower cover 10 of the vacuum chamber are reset, the equipment is started by induction, and continues to rotate. When the cam on the lower side of the layer of carrier frame 3 moves out of the arc groove in the cam disk 5 under rotation, the layer of carrier frame 3 is lifted up and goes to the subsequent station for curing work, and then continues to rotate. When the cam rotates to the next groove inside the cam disk 5, the operation is repeated for cooling work, and then it continues to rotate to the feeding station for unloading work.
