Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic module processing equipment, and in particular to a mechanical synchronous lifting device and method. Background Art

[0002] Large laminators are mechanical equipment that presses multiple layers of materials together. They are an important equipment required for manufacturing solar cell modules. The synchronization of the lifting and lowering of the laminating dynamic platen has an extremely important influence on the shape index and performance index of the pressed product. If the lifting and lowering of the dynamic platen are not synchronized, on the one hand, it will lead to uneven density of the entire laminate, and at the same time, the surface flatness is difficult to ensure, resulting in the scrapping of the laminate or too low yield rate.

[0003] The synchronous lifting of the existing laminated motorized platens mostly uses a gear rack structure to achieve mechanical synchronization. For example, Patent ZL200420035633.8 provides a mechanical synchronization device using double gears and racks to ensure the mechanical synchronization of the dynamic platen. The problem of using a gear rack structure to achieve mechanical synchronization is that: first, the cost of the gear rack structure device is relatively high; second, the installation process is relatively cumbersome, requiring all gears and racks to be on the same plane at the initial installation; finally, although the gear rack structure can ensure mechanical synchronization to a certain extent, there is still a gap between the gear and the rack, and it cannot be guaranteed that the initial installation state of all gears is consistent, so there is still some asynchronism, especially after long-term use, the gap between the gear and the rack will become larger. When the gap is too large, its synchronization cannot be guaranteed, resulting in the scrapping of the laminate. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a mechanical synchronous lifting device and method, which solves the problem of mechanical synchronous lifting of a large laminator and ensures the synchronization and stability of the lifting of the dynamic pressure plate.

[0005] The technical solution of the present invention is applied to a laminating machine, which includes a plurality of cross beams, each of which is connected to the same dynamic pressure plate through a pressure plate cylinder, and a synchronous lifting device includes a plurality of identical synchronous mechanisms, each of which is connected to the dynamic pressure plate through a synchronous mechanism so that various positions of the dynamic pressure plate can be synchronously moved, and each synchronous mechanism includes a rotating connecting plate, a connecting rod and a support, the support is connected to the dynamic pressure plate, one end of the connecting rod is rotatably connected to the support, one end of the rotating connecting plate is rotatably connected to the other end of the connecting rod, and the other end of the rotating connecting plate is fixedly connected to a through shaft, and a plurality of rotating connecting plates share a through shaft so that each rotating connecting plate can synchronously rotate around the axis center line of the through shaft, thereby causing various positions of the dynamic pressure plate to move synchronously, and the through shaft is rotatably connected to each cross beam.

[0006] Furthermore, each crossbeam is connected to the dynamic pressure plate via at least two synchronization mechanisms, and at least two synchronization mechanisms are arranged on both sides of the crossbeam.

[0007] Furthermore, a square tube is provided between each pressure plate cylinder and the cross beam to buffer the force exerted by the pressure plate cylinder on the cross beam.

[0008] Furthermore, the pressure plate cylinders on the multiple cross beams are arranged in a straight line and share a square tube.

[0009] Furthermore, each synchronous lifting device also includes a lifting cylinder, a fixed end of the lifting cylinder is connected to the crossbeam, and a telescopic end is connected to the dynamic pressure plate for preliminary pressing.

[0010] Furthermore, there are at least two lifting cylinders, and at least two lifting cylinders are arranged on both sides of the pressure plate cylinder.

[0011] Furthermore, a lifting cylinder is provided under the static pressure plate of the laminator to adjust the height of the static pressure plate.

[0012] Furthermore, the multiple beams are connected by at least two connecting rods.

[0013] The present invention also provides a mechanical synchronous lifting method. When performing the pressing work, the telescopic end of each pressure plate cylinder is telescopic to drive the dynamic pressure plate to move upward or downward. When the dynamic pressure plate moves up or downward, it drives the connecting rod to move up or downward, so that the rotating connecting plate drives the through shaft to rotate. Since multiple rotating connecting plates on the same side share a through shaft, the rotation angles of the multiple rotating connecting plates are consistent, thereby ensuring that the dynamic pressure plate remains stable throughout the entire working process.

[0014] The technical solution provided by the embodiment of the present invention has the following advantages compared with the prior art:

[0015] When the pressure plate cylinder of the present invention drives the dynamic pressure plate to perform pressing, the dynamic pressure plate drives the support to move, the support drives the connecting rod to move, and the connecting rod drives the connecting plate to rotate. Since several connecting plates are fixedly connected to the through shaft, each rotating connecting plate can rotate synchronously around the axial center line of the through shaft, thereby making the dynamic pressure plate move synchronously at various positions, ensuring that the dynamic pressure plate remains stable throughout the entire working process, solving the problem of mechanical synchronous lifting of large-scale laminating machines, and ensuring the synchronization and stability of the lifting of the dynamic pressure plate.

[0016] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through study and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] A specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation.

[0024] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “axial”, “radial”, “circumferential”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the technical solutions of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] In the description of the embodiments of the present invention, unless otherwise specified, “plurality” means two or more.

[0026] like Figure 1 , Figure 2 , Figure 3As shown, the present invention provides a mechanical synchronous lifting device, which is applied to a laminating machine 1. The laminating machine 1 includes a plurality of beams 2, each of which is connected to the same dynamic pressure plate 4 through a pressure plate cylinder 3. The synchronous lifting device includes a plurality of identical synchronization mechanisms 6. Each beam 2 is connected to the dynamic pressure plate 4 through the synchronization mechanism 6, so that the dynamic pressure plate 4 can move synchronously at various positions. Each synchronization mechanism 6 includes a rotating connecting plate 61, a connecting rod 62 and a support 63. The support 63 is connected to the dynamic pressure plate 4, one end of the connecting rod 62 is rotatably connected to the support 63, one end of the rotating connecting plate 61 is rotatably connected to the other end of the connecting rod 62, and the other end of the rotating connecting plate 61 is fixedly connected to a through shaft 7. A plurality of rotating connecting plates 61 share a through shaft 7, so that each rotating connecting plate 61 can rotate synchronously around the axial center line of the through shaft 7, thereby causing the dynamic pressure plate 4 to move synchronously at various positions. The through shaft 7 is rotatably connected to each beam 2.

[0027] When the pressure plate cylinder 3 of the present invention drives the dynamic pressure plate 4 to perform a pressing action, the dynamic pressure plate 4 drives the support 63 to move, the support 63 drives the connecting rod 62 to move, and the connecting rod 62 drives the connecting plate to rotate. Since several connecting plates are fixedly connected to the through shaft 7, each rotating connecting plate 61 rotates synchronously around the axial center line of the through shaft 7, thereby making the dynamic pressure plate 4 move synchronously at various positions, ensuring that the dynamic pressure plate 4 always remains stable during the entire working process, solving the problem of mechanical synchronous lifting of the large laminating machine 1, and ensuring the synchronization and stability of the lifting of the dynamic pressure plate 4.

[0028] It can be understood that the connecting rod 62 is rotatably connected to the support 63 via the first pin 64, and one end of the rotating connecting plate 61 is rotatably connected to the connecting rod 62 via the second pin 65, both of which ensure that there is a degree of freedom of rotation in the planar direction.

[0029] It can be understood that the rotating connecting plate 61 is fixedly connected to the through shaft 7 by a key, and the principle of constant distance between multi-link nodes is utilized to enable each rotating connecting plate 61 on the same side to rotate synchronously around the axial center line of the through shaft 7, thereby realizing mechanical synchronous lifting and lowering, so that the forces on each part of the dynamic pressure plate 4 are the same, thus avoiding the scrapping of the laminate due to uneven force during pressing.

[0030] In the embodiment provided by the present invention, each crossbeam 2 is connected to the dynamic pressure plate 4 via at least two synchronization mechanisms 6 , and at least two synchronization mechanisms 6 are arranged on both sides of the crossbeam 2 .

[0031] Furthermore, the synchronization mechanisms 6 on the same side share a through shaft 7, which has two functions: one is to ensure that all the movable pressure plates 4 are raised and lowered synchronously during the pressing, and the other is to connect several beams 2.

[0032] The specific number of the pressing plate cylinder 3 and the synchronization mechanism 6 can be set by those skilled in the art according to the requirements, and the present invention does not limit this.

[0033] Furthermore, a square tube 8 is provided between each pressing plate cylinder 3 and the cross beam 2 to buffer the force exerted by the pressing plate cylinder 3 on the cross beam 2 .

[0034] Furthermore, the pressure plate cylinders 3 of the multiple cross beams 2 are arranged in a straight line and share a square tube 8 .

[0035] It can be understood that a common square tube 8 can further connect several beams 2 .

[0036] It should be noted that when there are multiple pressure plate cylinders, they are arranged along the length direction of the cross beam 2. For example, if there are pressure plate cylinders and cross beams 2, the cylinders of the entire mechanical synchronous lifting device are arranged in the form of an ×, that is, each cylinder acts on the movable pressure plate 4 at the same time.

[0037] Furthermore, each cross beam 2 is provided with at least one lifting cylinder 9, the fixed end of at least one lifting cylinder 9 is connected to the cross beam 2, and the telescopic end is connected to the dynamic pressure plate 4 for preliminary pressing.

[0038] It can be understood that the function of several lifting cylinders 9 is to move the movable pressure plate 4 to the top of the material to be pressed, to preliminarily press the material, and to prepare for the pressing by several pressure plate cylinders 3 to prevent the material from shifting when the pressure plate cylinders 3 directly press, resulting in the laminate not meeting the requirements.

[0039] The specific number of the lifting cylinders 9 can be set by those skilled in the art according to their needs, and the present invention does not limit this.

[0040] It can be understood that since several lifting cylinders 9 are added for the initial pressing, it is necessary to increase the drooping distance of several pressing plate cylinders 3 so that several pressing plate cylinders 3 can effectively perform the secondary pressing.

[0041] Furthermore, a plurality of beams 2 are arranged on the base 1 at equal intervals.

[0042] It can be understood that the equal spacing arrangement can ensure that the dynamic pressure plate 4 is subjected to uniform force, and avoid the situation where the portion with too large a spacing cannot be subjected to force, resulting in incomplete pressing and causing the laminate to be scrapped.

[0043] Furthermore, a lifting cylinder 10 is provided below the static pressure plate 5 of the laminator 1 for adjusting the height of the static pressure plate 5 .

[0044] It can be understood that the height of the static pressure plate 5 is adjusted to adjust the pressing strength to adapt to the manufacture of different types of laminates, while avoiding excessive pressure that causes the laminate to be scrapped.

[0045] Furthermore, the multiple beams 2 are connected by at least two connecting rods 11 .

[0046] It can be understood that the connection of the connecting rod 11 is to further fix the multiple beams 2 to avoid shaking during operation.

[0047] The present invention also provides a mechanical synchronous lifting method. When pressing, the telescopic end of each pressure plate cylinder 3 is extended and retracted, driving the dynamic pressure plate 4 to move upward or downward. When the dynamic pressure plate 4 moves upward or downward, it drives the connecting rod 62 to move upward or downward, so that the rotating connecting plate 61 drives the through shaft 7 to rotate. Since multiple rotating connecting plates 61 on the same side share a through shaft 7, the rotation angles of the multiple rotating connecting plates 61 are consistent, thereby ensuring that the dynamic pressure plate 4 remains stable throughout the entire working process.

[0048] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0049] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and the embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily realized. Therefore, without departing from the general concept defined by the claims and equivalent scope, the present invention is not limited to the specific details and the illustrations shown and described here.
