Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic component laminating machine equipment, and particularly relates to a multi-layer synchronous lifting photovoltaic component laminating machine and a synchronous lifting system. Background Art

[0002] The prior art multi-layer photovoltaic module laminating machine includes more than two laminating main machines, each of which is stacked up and down. The opening and closing cover of each layer of the laminating main machine is driven by a lifting device. Since the output end of the lifting device is connected to the laminating main machine on the lowest layer, when opening and closing the cover, the lifting device drives the laminating main machine on the lowest layer to lift and lower, thereby pushing the laminating main machine above it to lift and lower, completing the opening and closing of the cover. For example, the Chinese utility model patent application number 202221666138.1 entitled "A Multi-layer Laminating Machine Lifting Device" discloses a multi-layer laminating machine lifting device and a laminating machine, which includes a lifting mechanism, the lifting mechanism includes a hydraulic cylinder and a lifting transition plate, the hydraulic cylinder is vertically fixed below the laminating mechanism near the bottom of the frame; the lifting transition plate is fixed on the telescopic rod of the hydraulic cylinder and corresponds to the laminating mechanism above it, a plurality of guide rollers are respectively fixed on the sides of the plurality of laminating mechanisms, and each guide roller is embedded in a slide groove opened at a right angle. In the working state, the hydraulic cylinder lifts the lifting transition plate, the lifting transition plate lifts the lowest laminating mechanism, the lowest laminating mechanism then lifts the next lowest laminating mechanism, and lifts up layer by layer in sequence, and finally the upper and lower adjacent laminating mechanisms are all pressed together. During this process, the guide rollers on each layer of laminating mechanism slide along the right-angled slide rails of the limit plate, thereby ensuring that each layer of laminating mechanism is lifted in the vertical direction; when it is necessary to take out the solar cell module between the two laminating mechanisms, the hydraulic cylinder telescopic rod contracts, the lifting transition plate is retracted to the top of the support frame, and the multi-layer laminating mechanisms fall vertically from bottom to top in sequence until the limit blocks of each layer of laminating mechanism are blocked by the inclined surface of the limit plate. At this time, each layer of laminating mechanism remains in the corresponding position, and the space between each two layers of laminating mechanisms is in an open state. The laminator adopts the above-mentioned lifting device structure, and its opening and closing covers have a sequence. When closing the covers, the cover at the bottom is closed first, and when opening the covers, the cover at the top is opened first. When the laminator has a large number of layers, the time for opening and closing the covers is relatively long, resulting in low overall work efficiency. Utility Model Content

[0035] The present invention will be further described in detail below through specific embodiments. The following embodiments are merely illustrative and non-restrictive, and should not be used to limit the scope of protection of the present invention.

[0036] like Figures 1-10As shown, the laminating machine of the present invention includes multiple laminating main machines and a synchronous lifting system. Each laminating main machine is provided with a laminating cavity for laminating photovoltaic modules. The laminating cavities of each laminating main machine are stacked up and down to form a multi-layer laminating machine. Each laminating cavity is composed of an upper cover 101 and a laminating workbench 102. The upper cover of each laminating cavity is located above the laminating workbench. In the two adjacent laminating main machines located in the middle layer, the laminating workbench of the laminating main machine located above and the upper cover of the laminating main machine located below constitute a laminating workbench assembly. In each laminating workbench assembly, the laminating workbench is located above the upper cover. Under the action of the synchronous lifting system, each layer of the laminating cavity can open and close the lid synchronously. When closing the lid synchronously, each layer of the laminating workbench assembly moves synchronously, and the laminating cavity closes the lid synchronously. When opening the lid, each layer of the laminating cavity opens the lid synchronously, allowing the stacking assembly 1 to be transferred in or out between the upper laminating workbench assembly and the lower laminating workbench assembly.

[0037] The synchronous lifting system of the present invention includes a lifting drive device, a scissor lift mechanism, a synchronous lifting vertical guide device 24, and a lamination chamber horizontal displacement compensation device 23. The lifting drive device usually adopts a linear reciprocating lifting drive device, such as a hydraulic cylinder, a screw nut reciprocating drive device, a gear rack reciprocating drive device or an electric cylinder drive device, as long as it can drive the fork arm lifting mechanism to achieve lifting. The lifting drive device and the scissor mechanism constitute a jacking mechanism. This patent application uses the example of a hydraulic cylinder as the lifting drive device for explanation. In this case, the jacking mechanism is called a hydraulic jacking mechanism. The scissor lift mechanism includes at least two sections of scissor lift arms 216. Each section of the scissor lift arm includes two cross-arranged scissor arms 2161 that are hingedly connected by a scissor pin 212. The number of sections of the scissor lift arm is set according to the number of layers of the lamination chamber. At least one section of the lamination chamber is correspondingly provided with a scissor lift arm. The two adjacent sections of the scissor lift arm are arranged in the upper and lower layers. The top end of the lower section of the scissor lift arm and the bottom end of the upper section of the scissor lift arm are hingedly connected by a horizontal guide wheel connecting pin 232 to form a combined lifting end of the scissor lift arm. The top end of the scissor lift arm located on the top layer is the top lifting end. Of course, if cost is not considered, the top layer can also adopt a combined lifting end structure. For the convenience of description, the combined lifting end and the top lifting end are collectively referred to as lifting ends. The bottom end of the scissor lift arm located on the bottom layer is connected to the horizontal roller 2163 provided on the frame through a horizontal roller 2162 for rolling connection, or is connected by a slider or a slide rail for sliding connection. Each lifting end of the scissor lift mechanism is connected to the horizontal displacement of the objects that need to be lifted, such as the laminating workbench components on the corresponding layer and the corresponding side, through the horizontal displacement compensation device. That is, when connected to the laminating machine, each layer of the laminating cavity has at least four connection points connected to the scissor lift mechanism, two connection points at the front and rear ends respectively. The front and rear ends of each layer of the laminating cavity are respectively connected to a lifting end of the scissor lift mechanism. Figure 1Taking the structure of a 4-layer laminating machine as an example, it uses a one-stage 4-layer laminating machine. A scissor lift mechanism is installed on both sides in front of the laminating machine, and a hydraulic jacking mechanism consisting of a scissor lift mechanism and a hydraulic cylinder is installed on the two sides behind the laminating machine. Each hydraulic jacking mechanism is equipped with a laminating chamber horizontal displacement compensation device. The lamination chamber horizontal displacement compensation device 23 includes a horizontal displacement mechanism and a horizontal displacement guide groove 239. The horizontal displacement guide groove is horizontally arranged, with its length direction parallel to the running direction of the lamination assembly, and is provided on the lamination workbench assembly. The horizontal displacement mechanism is slidably connected or rollingly connected to the horizontal displacement guide groove. The horizontal displacement mechanism can be a slider, or a guide wheel or roller. Preferably, the horizontal displacement mechanism uses a guide wheel assembly. The guide wheel assembly 6 includes a guide bearing 61, a guide pin 62, a guide pin sleeve 63, and a guide limit spring 64. The guide bearing is rotatably arranged outside the guide pin, with a limit spring provided at one end and a guide pin sleeve mounted on the other end. The guide bearing of the guide wheel assembly is located in the horizontal displacement guide groove 239 and can move horizontally along the horizontal displacement guide groove. The guide pin is fixedly connected to the lifting end of the scissors lift mechanism through the guide pin sleeve 63, thereby realizing a horizontal displacement movable connection between the scissors lift mechanism and the lamination workbench assembly. Usually, the scissors arms are made of rectangular tubes or rectangular plates, and the horizontal guide wheel connecting pin 232 also serves as the guide bearing 61. To prevent the scissor lift arm and the laminating workbench from slipping during the lifting process, a laminating workbench slot plug 235 is provided between the guide bearing and the guide pin sleeve. The laminating workbench slot plug closes the opening of the horizontal displacement guide groove on the laminating workbench, sealing the guide bearing in the horizontal displacement guide groove. The guide sleeve and the guide pin are both located outside the horizontal displacement guide groove, preventing the guide wheel assembly from slipping out of the horizontal displacement guide groove, which is beneficial to the stable operation of the system. A horizontal displacement guide groove side opening is provided at the end of the laminating workbench assembly. The guide groove side opening can facilitate the disassembly and assembly of the guide pin. A guide wheel plug is fixedly provided on the side opening to prevent the guide wheel assembly from slipping out of the side opening. The guide pin of the guide wheel assembly serves to connect the top end of the lower scissor lift arm with the bottom end of the upper scissor lift arm, and also serves as the horizontal guide wheel connecting pin 232 connecting the two. The use of the above-mentioned horizontal displacement compensation device can not only absorb the lateral movement displacement of the scissor lift arm, but also prevent the laminating chamber from shaking during the lifting process. The output rod of the hydraulic cylinder is hingedly connected to the scissor pin connecting the two scissor arms, preferably through a hydraulic cylinder joint 213.

[0038] Preferably, the hydraulic cylinder output rod is hingedly connected to the scissor lift arm via a lifting connection mechanism 210. Figure 3As shown, the jacking connection mechanism 210 includes a scissor pin shaft 212, a hydraulic cylinder joint 213 and a clamping nut 214. The hydraulic cylinder joint is U-shaped, and a through hole is provided at the bottom thereof for the hydraulic cylinder output rod to pass through. A connecting thread is provided at the end of the hydraulic cylinder output rod. The clamping nut and the connecting thread are threadedly connected to fix the hydraulic cylinder output rod and the hydraulic cylinder joint together. Through holes are respectively provided on the two side arms of the hydraulic cylinder joint for the scissor pin shaft to pass through. The insertion end of the scissor pin shaft is limited by a limit spring 211.

[0039] It is best to set up a hydraulic jacking synchronization control mechanism, and each hydraulic cylinder is connected to the hydraulic jacking synchronization control mechanism respectively, and is controlled by the hydraulic jacking synchronization control mechanism to perform synchronous lifting and lowering. The hydraulic jacking synchronization control mechanism of the existing technology can be used for control, which will not be described in detail here.

[0040] In the preferred structure, each section of the scissor lift arm is movably connected to the hydraulic cylinder by a synchronous lifting vertical guide device that moves up and down. The synchronous lifting vertical guide device is also called a jacking guide mechanism, which can be a guide device composed of a slider and a slide rail, or a guide device composed of a guide column and a guide sleeve. In the present invention, the following jacking guide mechanism is preferably adopted, and the jacking guide mechanism includes a stand 244 located on both sides of the lamination chamber, and a vertical displacement guide groove 242 is provided on the stand in the vertical direction, and the scissor pin shaft is slidably connected to the vertical displacement guide groove. The length of the vertical displacement guide groove must be greater than or equal to the opening stroke of each layer of the lamination chamber. The number and height of the vertical displacement guide groove 242 match the number of sections of the scissor lift arm, and each section of the scissor lift arm is correspondingly equipped with a vertical displacement guide groove.

[0041] The synchronous lifting system adopting this structure is controlled by the hydraulic jacking synchronous control mechanism to control the action of each hydraulic cylinder, the scissor lift arm drives the upper cover of each laminating chamber to rise and fall, and the guide wheel assembly moves horizontally in the horizontal displacement guide groove, absorbing the horizontal movement distance of the fork arm end and limiting the upper cover in the horizontal direction, greatly reducing the horizontal shaking of the laminating workbench assembly. The fork arm pin of the jacking guide mechanism moves up and down in the vertical displacement guide groove to limit the movement direction of the fork arm in the vertical direction. The two work together to effectively prevent the laminating workbench assembly from being misaligned in the horizontal direction during the lifting process, ensuring the position accuracy of the opening and closing cover and the stability of the laminating workbench assembly. More preferably, the hydraulic cylinder extension rod is connected to the vertical displacement guide groove through a guide wheel assembly 6 for sliding fit. The fork arm pin 212 also serves as the guide pin 62 of the guide wheel assembly of the synchronous lifting vertical guide device, and the guide pin sleeve 63 of the guide wheel assembly is fixedly connected to the end of the fork arm. A guide frame slot blocking plate 245 is provided on the vertical displacement guide slot to block the guide bearing 61 .

[0042] The multi-layer synchronous lifting photovoltaic module laminating machine of the present invention is adopted. The laminating workbench components that constitute each laminating chamber are connected to the lifting end of the scissors-type lifting arm through a horizontal displacement compensation device. The object to be lifted is located on the side of the scissors-type lifting arm and is connected to the lifting end of the corresponding height, rather than being located on the top of the overall scissors-type lifting mechanism. Therefore, a scissors-type lifting mechanism can be equipped with multi-section scissors-type lifting arms depending on the number of lifted objects, and thus has multiple lifting ends, and can lift multiple objects at the same time. When specifically applied to a multi-layer synchronous lifting photovoltaic module laminating machine, multiple laminating hosts can be lifted synchronously, truly realizing the synchronization of each layer of laminating machines. The hydraulic cylinders are controlled to lift synchronously through a jacking synchronization control mechanism, truly realizing multi-layer linkage synchronous lifting.

[0043] In the present invention, guide wheel assemblies are provided at the top of the scissor lift arm and at the hinge points of two adjacent scissor lift arms. These guide wheel assemblies are horizontally connected to the horizontal displacement guide grooves provided on the laminating workbench assembly. The hinge points of the two scissor arms are also vertically connected to the vertical displacement guide grooves provided on the stand via the guide wheel assemblies. This prevents the laminating workbench assembly from shifting in the front-to-back direction when the cover is opened and closed, ensuring the accuracy of the cover opening and closing. The above structure not only drives the synchronous opening and closing of the covers of the laminating chambers on the same layer, but also drives the synchronous opening and closing of the covers of the laminating chambers on different layers, truly realizing the large-scale linkage of the opening and closing covers of multiple layers.

[0044] In order to further increase the accuracy of opening and closing the cover, a cavity lifting guide device 4 is provided. When the cavity is raised or lowered, the cavity is limited in horizontal movement. The cavity lifting guide device includes two guide wheels with vertically arranged axles, referred to as right-angle guide wheels 41. The right-angle guide wheels are fixedly arranged on the upper cover 101 of each layer of the laminating main machine through a right-angle guide wheel mounting frame 42. Four right-angle guide wheels are usually provided on the upper cover. A pair of right-angle guide wheels are respectively provided on the left and right sides of the upper cover. A pair of right-angle guide wheels are provided at the edge of the upper cover in front and back. Guide columns 43 are provided at positions corresponding to the positions of the right-angle guide wheels, that is, two rectangular guide columns are provided on the left and right sides respectively. The laminating workbench assembly is located between the four guide columns. Two guide wheels in the right-angle guide wheels are respectively connected in rolling connection with the two vertical side surfaces of the guide columns. When the laminating workbench assembly shakes during the lifting process, the rollers provided on the upper cover are connected in rolling connection with the guide columns on the corresponding side, and are guided by the guide columns to prevent the laminating workbench assembly from shaking back and forth and left and right. With this structure, when the laminating workbench assembly is offset, it will be limited by two vertically arranged guide wheels. Therefore, its front, back, left and right offsets are determined by the position error between the guide column and the upper cover. By adjusting the position error, the opening and closing accuracy of the upper cover can be adjusted.

[0045] When the laminating machine is a laminating and curing laminating machine, the laminating workbench also serves as a heating table. The vertical frame can adopt a gantry frame.

[0046] The synchronous lifting system of the present invention can also lift multiple groups of objects to be lifted in multiple layers. Each group of objects to be lifted is called a section. In this case, more than three lifting mechanisms need to be set. Since scissor arms need to be set on both sides of the objects to be lifted, generally more than three pairs of lifting mechanisms are set. The scissor arms of the lifting mechanisms set in pairs on both sides of the objects to be lifted are fixedly connected by a linkage rod 2164, so that the synchronous lifting system is stable and has good synchronization. The two lifting mechanisms set in pairs can share a lifting drive device or set up lifting drives separately. Each lifting drive device is connected to a lifting synchronization control mechanism to achieve synchronous action. For example, when a hydraulic cylinder is used as a lifting drive device, a hydraulic synchronous lifting control device can be used to control the action of the hydraulic cylinder. Each hydraulic cylinder is connected to a lifting synchronization control mechanism. When used for the opening and closing cover of a multi-section multi-layer laminating machine, each lifting end of each lifting mechanism is connected to a laminating workbench assembly at a corresponding height at a corresponding position through a laminating chamber horizontal displacement compensation device, and the fork arm pins of each scissor arm are connected to the scissor arm through a synchronous lifting vertical guide device.
