Description

Technical Field

[0001] The utility model belongs to the technical field of laminating equipment, in particular to a multi-layer photovoltaic component laminating machine. Background Art

[0002] With the continuous upgrading of photovoltaic module laminating equipment, each main engine manufacturer is developing multi-layer laminating machines with 3, 4, 6 or 8 layers. In the existing multi-layer laminating machines, each layer of the laminating machine is stacked up and down, and each layer moves in the same direction. As the number of layers increases, more and more problems arise. The main problems are as follows:

[0003] 1. When lifting, it is necessary to lift layer by layer. The lifting time of the entire laminator is the sum of the lifting time of each layer. The more layers there are, the more time it takes;

[0004] 2: The higher the lift, the longer the cylinder rod of the actuator (hydraulic cylinder or pneumatic cylinder), the lower the balance after extension, and the more likely it is to be damaged;

[0005] 3: The higher the lift, the longer the travel of the top working unit will be, and the more difficult it will be to arrange the vacuum tubes and cables connected to it;

[0006] 4: The more layers there are, the greater the pressure on the bottom working unit after all layers fall, and the greater the difference in sealing between the top and bottom layers, which is not conducive to improving the vacuum degree;

[0007] 5: The more layers there are, the greater the force the connection between the top layer and the second top layer will bear, and additional costs will be required for reinforcement. Utility Model Content

[0008] The purpose of the present utility model is to provide a split-type multi-layer laminating machine to address the technical problems in the prior art multi-layer laminating machines, in which the laminating main machines of each layer are stacked up and down, and the covers all move in one direction when opened and closed, resulting in a long lifting and merging time, poor working stability of the lifting drive device, easy damage, high pressure on the laminating unit located at the bottom layer, and a greater difference in sealing between the top and bottom layers, which is not conducive to improving the vacuum degree.

The output end of the lifting drive device of the laminating unit is fixedly connected, the lower laminating unit located on the bottom layer is fixedly connected to the output end of the lifting drive device of the lower laminating unit, the lifting drive device of the upper laminating unit has a stroke opposite to that of the lifting drive device of the lower laminating unit, the lifting drive device of the upper laminating unit drives the upper laminating unit located on the top layer to move up and down, thereby driving each upper laminating unit to move toward or behind the middle laminating unit, and the lifting drive device of the lower laminating unit drives the lower laminating unit located on the bottom layer to move, thereby driving each lower laminating unit to move toward or behind the middle laminating unit, thereby completing the closing or opening of the laminating unit;

[0011] The interconnection mechanism includes an interconnection rod and an interconnection plate. Each laminating unit is provided with an interconnection plate. An interconnection rod is provided between the interconnection plates of adjacent laminating units. One end of the interconnection rod is movably connected to one of the interconnection plates, and the other end is fixedly connected to the interconnection plates. Thus, the lifting drive device of the lower laminating unit drives the lower laminating unit located at the bottom layer to move, thereby driving each lower laminating unit to move toward or behind the middle laminating unit, thereby completing the closing or opening of the laminating unit.

[0012] The laminating unit includes a laminating platform, a cover plate, a rubber plate and a pressure strip. The cover plate is located below the laminating platform, and the two are fixedly connected by a rib plate to form a box structure. The rubber plate is located below the cover plate, and its periphery is pressed tightly by the pressure strip and fixedly connected to the cover plate.

[0030] The present invention will be further described in detail below through specific examples. The following examples are only illustrative and not restrictive, and should not be used to limit the scope of protection of the present invention. Figure 1 The position shown is used as an example to explain the orientation.

[0031] like Figure 1-Figure 7 As shown, Figure 1 As shown, the utility model provides a split-type multi-layer laminating machine, such as Figure 1-7 Only the main components of the laminator are shown; other parts are not shown. The laminator is composed of multiple laminating units. This embodiment provides a multi-layer laminator composed of seven laminating units capable of simultaneously placing six layers of photovoltaic modules. In practice, the number of laminating units can be configured according to needs. The laminating units on each layer have the same structure and are interchangeable.

[0032] like Figure 2 As shown, in the present invention, the central laminating unit is referred to as the middle laminating unit. The middle laminating unit 1A is stationary. The laminating units located above it are collectively referred to as the upper laminating units, namely, upper laminating unit 1B, upper laminating unit 2 1C, and upper laminating unit 3 1D. The laminating units located below it are collectively referred to as the lower laminating units, namely, lower laminating unit 1E, lower laminating unit 2 1F, and lower laminating unit 3 1G. Both the upper and lower laminating units are movable up and down. Upper laminating unit 1B, upper laminating unit 2 1C, and upper laminating unit 3 1D are raised and lowered above the middle laminating unit 1A, while lower laminating unit 1E, lower laminating unit 2 1F, and lower laminating unit 3 1G are raised and lowered below the middle laminating unit 1A. The middle laminating unit 1A is secured to an equipment frame (not shown) via multiple fixing plates 5.

[0033] The middle laminating unit 1A, upper laminating unit 1B, upper laminating unit 2 1C, upper laminating unit 3 1D, lower laminating unit 1E, lower laminating unit 2 1F, and lower laminating unit 3 1G are interconnected and movably connected via an interconnection mechanism. During lifting, the interconnection mechanism enables movement and limiting between adjacent laminating units. Specifically, the interconnection mechanism includes a plurality of interconnection rods 4 and a plurality of interconnection plates 106. At least two interconnection plates 106 are provided on the front and rear sides of the main structure of each laminating unit, respectively. The interconnection plates 106 extend beyond the main structure. The interconnection plates of each laminating unit are arranged relative to each other in the upper and lower directions. An interconnection rod is provided between the interconnection plates of two adjacent laminating units. One end of the interconnection rod is fixedly connected to the interconnection plate, and the other end passes through a through hole provided on the interconnection plate and movably connects to the interconnection plate. The interconnection rod is limited by a limiting device to prevent it from separating from the movably connected interconnection plate. The limiting device can be a fastening nut, a latch, etc. It is best if the lengths of the interconnection rods are equal, so that each laminating unit can obtain a consistent stroke.

[0034] The upper laminating unit and the lower laminating unit are respectively equipped with a lifting drive device and can be lifted and lowered independently. The upper laminating unit 1D at the top layer is called the top laminating unit and the lower laminating unit 1G at the bottom layer is called the bottom laminating unit. They are respectively connected by a lifting connecting plate 2 and a lifting drive device 3. The lifting drive device is preferably a hydraulic cylinder or a pneumatic cylinder. Each lower laminating unit and each upper laminating unit are equipped with more than two lifting drives. The lifting drives are evenly distributed on the front and back sides of the laminating unit to keep the laminating unit stable. The hydraulic cylinder or cylinder base connected to the top laminating unit 1D is fixed on the same horizontal plane of the equipment frame to control the lifting of the upper laminating unit above the middle laminating unit 1A; the hydraulic cylinder or cylinder 3 base connected to the bottom laminating unit 1G is fixed on another horizontal plane of the equipment frame to control the lifting of the lower laminating unit below the middle laminating unit 1A. As shown in the figure, in this embodiment, two sets of lifting drive devices are respectively arranged on the front and rear sides of each laminating unit, and each set of lifting drive devices is fixedly connected to the upper laminating unit 1 on the top layer and the lower laminating unit 3 on the bottom layer through a lifting plate. The output directions of the two drive devices are opposite. Thus, when the two lifting drive devices are in operation, the upper laminating unit (i.e., the top laminating unit) located on the uppermost layer and the lower laminating unit (i.e., the top laminating unit) located on the lowermost layer both move along the interconnected rods. When upper laminating unit 1 moves downward and reaches its stroke, that is, when it moves into position along its interconnected rods, it contacts upper laminating unit 1 and pushes upper laminating unit 2 to move along its interconnected rods. When upper laminating unit 2 reaches its stroke, it pushes upper laminating unit 3 to move along its interconnected rods until it merges with the middle laminating unit. When lower laminating unit 3 moves upward and reaches its stroke, it merges with lower laminating unit 2 and pushes lower laminating unit 2 upward along its interconnected rods. When it reaches its stroke, lower laminating unit 2 pushes upper laminating unit 1 upward, thereby merging with the middle laminating unit, thus completing the merging of the laminating units. When lifting, the stroke is reversed. Because the stacking units are divided into two groups, the travel distance of each stacking unit connected to the drive device is shortened by half compared to ungrouped stacking units. This reduces travel time and combined lifting time. Furthermore, the number of drive outputs is reduced by half, improving stability. Furthermore, because the middle stacking unit is fixed, the weight force on the bottom stacking unit is also reduced by half.

[0035] When the laminating machine is working, all upper laminating units including upper laminating unit 1B, upper laminating unit 2 1C, upper laminating unit 3 1D and all lower laminating units including lower laminating unit 1 1E, lower laminating unit 2 1F, lower laminating unit 3 1G move at the same time and are in an open state. Figure 2 As shown; after all photovoltaic modules in each lamination cavity are placed, all upper lamination units and all lower lamination units act simultaneously and are in a merged state, as shown in FIG. Figure 3 shown.

[0036] like Figure 4-Figure 7 As shown, the laminating unit 1 of the embodiment structure of the present invention can adopt the following structure, including a laminating platform 101, a cover plate 102, a pressure strip 103, a driving shaft group 104, and a follower shaft group 105. The cover plate 102 is located below the laminating platform 101. The laminating platform 101 and the cover plate 102 are an integrated box structure, and a rib plate is provided between the two, and the box structure is fixedly connected by the rib plate. A rubber plate and a pressure strip are provided below the cover plate, and the rubber plate is fixedly connected to the bottom of the cover plate by pressing the pressure strips around. The upper surface of the laminating platform 101 is used to place the pressurized photovoltaic components. The cover plate 102 can cooperate with the laminating platform of the laminating unit located below it through the connected pressure strips 103 to form a vacuum cavity. As shown Figure 7 As shown, when the laminating units are combined, the adjacent two laminating units cooperate to form a sealed cavity, that is, the cover plate and the pressure strip of the laminating unit located above and the laminating platform of the laminating unit located below form a sealed cavity, commonly known as a vacuum cavity, which is used to receive and accommodate photovoltaic modules. The photovoltaic modules are cured and laminated in the vacuum cavity, which is also called a packaging operation. The lower surface of each cover plate is a groove structure, which is sealed by a rubber plate 107 to form an upper chamber. The four sides of the rubber plate 107 are fixedly connected to the cover plate 102 by the pressure strip 103 and the fixing device. A sealing strip is set between the pressure strip and the rubber plate, and a sealing strip is also set at the lower end of the pressure strip to form a seal with the laminating unit located below when the two laminating units are combined. When the two laminating units are combined, the pressure strip 103 is sealed with the laminating platform of the lower laminating unit through the sealing strip to form a lower chamber. The high-temperature cloth is sandwiched between the laminating platform, the pressure strip and the sealing strip. During operation, the upper chamber is first evacuated. Once the vacuum reaches a predetermined value, the lower chamber is then evacuated. Finally, the upper chamber is inflated to compress the photovoltaic modules, completing the packaging process. The driving shaft assembly 104 and the follower shaft assembly 105 are located on the left and right ends of the laminating platform, respectively, and are connected by a high-temperature transmission cloth. The high-temperature cloth surrounds the laminating platform and the pressure strips. The driving shaft assembly 104, the follower shaft assembly 105, and the high-temperature cloth form a circulating transmission system for transporting the photovoltaic modules to the laminating platform. The interconnection plate 106 is fixed to the outside of the box formed by the laminating platform 101 and the cover plate 102. It is connected in series by the interconnection rod 4 and is used to drive the lifting and lowering movement of the laminating unit.

[0037] Of course, lamination units of other structures may also be used, as long as they can complete the packaging of photovoltaic modules.

[0038] Preferably, the total number of layers in the laminating unit is an odd number, with the upper and lower laminating units having the same number of layers, such as 5, 7, or 9 layers. Of course, the number of layers in the laminating unit can also be an even number, with the upper and lower laminating units having different numbers of layers, such as 4, 6, 8, or 10 layers. The upper and lower laminating units differ in number of layers by one layer.

[0039] The beneficial effects of the multi-layer laminating machine using the structure of dividing the laminating units into two groups, the upper and lower groups, and the number of laminating units in the upper and lower groups is equal are as follows:

[0040] 1: Lifting and closing time is shortened by 50%: the upper and lower laminating units can move simultaneously, and the time is halved;

[0041] 2: The extension distance of the cylinder or hydraulic cylinder is shortened, the service life is increased, the stability is increased, and the walking accuracy is improved;

[0042] 3: The layout of pipelines and lines is simpler, the height difference is shortened, and the reliability is increased;

[0043] 4: The relative pressure between each layer is more balanced and the difference is not too large, which helps to increase the life of the seal;

[0044] 5: The vacuum degree of each chamber is not much different, thereby improving the overall vacuum degree;

[0045] 6: The strength required for interconnecting rods and interconnecting plates between each layer is reduced, which is conducive to cost reduction and efficiency improvement.

[0046] Of course, as a fine-tuning measure, the laminating units can be grouped appropriately based on their number of layers. For example, when the number of layers is large, the units can be divided into three or four groups. The number of laminating units in each group can be equal or unequal, but equal numbers are preferred to facilitate coordinated control by the control system. A stationary laminating unit can be placed between two groups of laminating units. The stationary laminating unit is fixedly connected to the frame. This effectively reduces the travel of the drive unit, saving switching time and improving efficiency.
