Description

Technical Field

[0001] The utility model belongs to the technical field of laminating machines, and particularly relates to a multi-section and multi-chamber laminated component laminating machine. Background Art

[0002] In the existing multi-section laminating chamber laminating machine, the front and rear section laminating chambers are respectively equipped with lifting devices to realize the opening and closing of the laminating chamber body. Since the opening and closing of each section of the laminating chamber are independently set, the working beats of each section of the laminating chamber cannot be completely consistent, and there are differences in the opening and closing times of each section of the laminating chamber. When transmitting the laminated component into the laminating chamber, it is necessary to wait until the opening and closing of each section of the laminating chamber are in place before transmitting the laminated component, which reduces the production efficiency. In addition, in adaptation to the non-synchronous opening and closing of each section of the laminating chamber, the laminated components in each section are also independently transmitted, so that the transmission positions of the laminated components in each section are inaccurate, causing the components to be contaminated by overflow glue in different chambers, affecting the quality of the components, increasing the cleaning difficulty of the residual glue generated by the overflow glue, and increasing the workload of maintenance personnel. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a synchronous lifting large linkage laminating machine for the deficiencies of the existing multi-section and multi-chamber laminating machine, in which the opening and closing of each section are independently controlled, and the transmission of the laminated components in each section is independently transmitted, resulting in inaccurate positions of the laminated components received by the vacuum cabins in each section and causing the components to be contaminated by overflow glue in different chambers.

[0006] A synchronous lifting vertical guiding device is also provided. The synchronous lifting vertical guiding device includes a vertical frame. A vertically arranged vertical displacement guide groove is arranged on the vertical frame. The scissor pin shaft is slidably and cooperatively connected to the vertical displacement guide groove. Synchronous lifting vertical guiding devices are respectively arranged on both sides of the front and back ends of each vacuum cabin;

[0007] The synchronous lifting large linkage laminator is a multi-section and multi-layer laminator. The laminating main machines of each layer in each section are stacked up and down. When there are more than three layers, the upper covers and heating plates of the laminators of adjacent layers are fixedly connected together to form a heating plate assembly. The horizontal displacement guide groove is arranged on the heating plate assembly. The number of sections of the scissor lifting arm in the scissor lifting mechanism corresponds to the number of layers of the laminator. At least one section of scissor lifting arm is correspondingly arranged for each layer of laminator. Each layer of vacuum cabin is horizontally movably connected through a horizontal displacement compensation device with a lifting end of the scissor lifting arm corresponding to its height. Vertically arranged vertical displacement guide grooves are respectively arranged on the vertical frame at positions corresponding to the scissor pin shafts of each section of scissor lifting arm;

[0008] The adjacent ends of two adjacent vacuum cabins share a hydraulic lifting mechanism. The front and back two lifting ends of the scissor lifting arm are respectively connected to the components to be lifted of the corresponding side of the vacuum cabin. The components to be lifted are located between two adjacent hydraulic lifting mechanisms;

[0009] The guide wheel assembly further comprises a guide bearing and a guide pin, wherein the guide bearing is rotatably arranged at one end of the guide pin, and a guide pin sleeve is sleeved at the other end of the guide pin, and a limit spring is arranged on the guide pin at the end of the guide bearing opposite to the guide sleeve, and the guide sleeve and the retaining spring jointly limit the guide bearing. The translation mechanism adopts the structure of the guide wheel assembly, the guide bearing is in rolling connection with the horizontal displacement guide groove, the scissor fork arm is in rolling connection with the vertical displacement guide groove through the guide wheel assembly, and the guide pin is a scissor fork pin;

[0010] A cavity lifting guide device is also provided, which includes two guide wheels vertically arranged on the axles and two guide columns respectively arranged on the left and right sides of the vacuum cabin.

[0013] The advantages and beneficial effects of the utility model are:

[0014] The large-scale synchronous lifting linkage laminating machine adopts the structure of the utility model, and under the action of the combined synchronous lifting system, the vacuum cabin cavity of each section is opened and closed at the same time. Compared with the traditional multi-layer laminating machine, each vacuum cabin has an independent opening and closing cover. The laminated components can be driven by the same transmission mechanism and carried out on the same plane. The large-scale linkage of the transmission of each laminated component of the multi-layer laminating machine is realized, and the precise positioning of the transmission of the laminated components is realized. The overflow of glue in the laminating process will be in a fixed overflow area, and each vacuum cabin will not be independently transmitted, with inaccurate positioning, causing the components to be contaminated by overflowed glue in different walls, increasing the difficulty of cleaning the residual glue caused by overflowed glue, and increasing the workload of maintenance personnel.

[0015] Furthermore, the same side positions of the vacuum cabins of each layer of each section of the laminating main machine are connected to the lifting end of the same scissor lift mechanism, and the scissor arms are synchronized during the lifting process. Therefore, the opening and closing of the vacuum cabins of each layer are synchronized. Compared with the structure of the prior art laminating machine in which the vacuum cabins are closed one by one from top to bottom or from bottom to top, the time for opening and closing the multi-layer laminating machine is reduced, and the problem of local melting of the packaging film of the laminated component caused by the prior art multi-layer laminating machine closing the cover layer by layer can be solved. When vacuuming, the air in the laminated component cannot be completely discharged, resulting in degradation of the bubble quality of the component after lamination or scrapping.

[0032] The following further details the present utility model through specific embodiments. The following embodiments are only descriptive and not restrictive, and the protection scope of the present utility model cannot be limited thereby.

[0033] As Figures 1-8 shown, the synchronous lifting large - linkage laminator of the structure of the present utility model is a multi - section laminator, which includes at least two sections of lamination main machines. Each section of lamination main machine includes a vacuum cabin, and the vacuum cabins of each section are arranged in the front - and - back direction. According to the number of layers of each vacuum cabin, it is divided into a single - layer multi - section laminator and a multi - layer multi - section laminator. Each vacuum cabin is composed of an upper cover 101 and a heating plate 102. The upper cover of each vacuum cabin is located above the heating plate. When the upper cover and the heating plate are combined together, a sealed vacuum cabin is formed. When it is a multi - layer multi - section laminator, the vacuum cabins of each section are stacked up and down. The upper covers and heating plates of the adjacent upper and lower vacuum cabins are fixedly connected and combined together to form a heating plate assembly 100. The heating plate assembly located above is simply called the upper heating plate assembly, and the heating plate assembly located below is simply called the lower heating plate assembly. In each heating plate assembly, the heating plate is located above the upper cover. Under the action of the combined synchronous lifting system, the vacuum cabins of each section and each layer are opened and closed simultaneously. When closing the cover, a sealed vacuum cabin is formed. When opening the cover, the laminated component 1 is allowed to be transported into or out of the space between the upper heating plate assembly and the lower heating plate assembly. For better heat preservation, preferably, the upper cover of the lamination main machine at the top layer is also composed of a heating plate assembly. For the convenience of description, when only the upper cover is provided for the lamination main machine at the top layer, this upper cover is also collectively referred to as the heating plate assembly. The combined synchronous lifting system of the present utility model adopts the following structure: It includes a hydraulic jacking mechanism 21, a hydraulic jacking synchronous control mechanism (not shown in the figure), and a vacuum cabin horizontal displacement compensation device 23. As Figure 1As shown, the hydraulic cylinder and the scissor lift mechanism form the hydraulic lifting mechanism 21. The scissor lift mechanism includes at least one section of scissor lift arms 216. Hydraulic lifting mechanisms are respectively arranged on both sides and both ends of each vacuum cabin, so that the front and rear ends and the left and right sides of each vacuum cabin are supported and lifted by the hydraulic lifting mechanisms, maintaining the balance and stability of the vacuum cabin. A hydraulic lifting mechanism is shared between two adjacent laminators. Each section of scissor lift arm includes two scissor sub-arms 2161 that are cross-arranged and hinged together through scissor pins 212. The number of sections of scissor lift arms is set according to the number of layers of the vacuum cabin. At least one section of scissor lift arm is correspondingly arranged for at least one layer of vacuum cabin. When the number of layers of the vacuum cabin is two or more, two or more sections of scissor lift arms are correspondingly arranged. The adjacent two sections of scissor lift arms are arranged in upper and lower layers. The top end of the lower section of scissor lift arm is hinged to the bottom end of the upper section of scissor lift arm through a horizontal guide wheel connecting pin 232, forming a combined lifting end of the scissor lift arm. The top end of the scissor lift arm at the top layer is the top layer lifting end. Of course, if cost is not considered, the top layer can also adopt the structure of the combined lifting end. For the convenience of description, both the combined lifting end and the top layer lifting end are collectively referred to as the lifting end. The bottom end of the scissor lift arm at the bottommost layer is in rolling connection with a horizontal roller path 2163 arranged on the frame through a horizontal roller 2162, or in sliding connection through a slider or a slide rail. Each lifting end of each scissor lift mechanism is horizontally and displaceably connected to the heating plate assembly on the corresponding layer and corresponding side through a horizontal displacement compensation device. That is, there are at least four connection points on each layer of vacuum cabin connected to the scissor lift mechanism, with two connection points at each of the front and rear ends. The front and rear ends of each layer of vacuum cabin are respectively correspondingly connected to a lifting end of the scissor lift mechanism. To Figure 1Taking a two-stage four-layer laminator as an example, a scissor lift mechanism is respectively arranged on both sides in front of the first-stage lamination main machine, a scissor lift mechanism is respectively arranged on both sides between the first-stage and the second-stage lamination main machines, and a hydraulic jacking mechanism composed of a scissor lift mechanism and a hydraulic cylinder is respectively arranged on both sides behind the second-stage lamination main machine. Each hydraulic jacking mechanism is equipped with a horizontal displacement compensation device for the vacuum cabin. The horizontal displacement compensation device 23 for the vacuum cabin includes a horizontal displacement mechanism and a horizontal displacement guide groove 239. The horizontal displacement guide groove is horizontally arranged, and its length direction is parallel to the running direction of the laminated assembly. It is opened on the heating plate assembly. The horizontal displacement mechanism is slidably or rollably connected to the horizontal displacement guide groove. The horizontal displacement mechanism can be a slider, or a guide wheel or a roller can be used. Preferably, the horizontal displacement mechanism uses a guide wheel assembly. The guide wheel assembly 6 includes a guide bearing 61, a guide pin shaft 62, a guide pin shaft sleeve 63 and a guide limit snap ring 64. The guide bearing is rotatably arranged outside the guide pin shaft. A limit snap ring is arranged at one end, and a guide pin shaft sleeve is sleeved at 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 shaft is fixedly connected to the lifting end of the scissor lift mechanism through the guide pin shaft sleeve 63, so as to realize the horizontal displacement movable connection with the heating plate assembly. Usually, the scissor arms are made of profiled 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 arms from slipping off the heating plate during the lifting process, a heating plate notch plug 235 is arranged between the guide bearing and the guide pin shaft sleeve. The heating plate notch plug closes the opening of the horizontal displacement guide groove on the heating plate and encloses the guide bearing in the horizontal displacement guide groove, while the guide pin shaft sleeve and the guide pin shaft 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 side opening of the horizontal displacement guide groove is arranged at the end of the heating plate assembly. The side opening of the guide groove facilitates the disassembly and assembly of the guide pin shaft. A guide wheel plug is fixedly arranged on the side opening to prevent the guide wheel assembly from slipping out from the side opening. The guide pin shaft of the guide wheel assembly plays the role of connecting the top of the lower scissor lift arm and the bottom of the upper scissor lift arm, and also serves as the horizontal guide wheel connecting pin 232 for connecting the two. When only one layer of vacuum cabin is arranged, that is, the so-called single-layer vacuum cabin, the two tops of the scissor lift arms are horizontally movably connected to the heating plate assembly through the horizontal displacement compensation device. Using the above horizontal displacement compensation device can not only absorb the lateral movement displacement of the scissor lift arms, but also prevent the vacuum cabin 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.

[0034] Preferably, the output rod of the hydraulic cylinder is hingedly connected to the scissor lift arm through a jacking connection mechanism 210. As Figure 3As shown, the jacking connection mechanism 210 includes a shear pin 212, a hydraulic cylinder joint 213, and a compression nut 214. The hydraulic cylinder joint is U-shaped with a through hole provided at its bottom for the output rod of the hydraulic cylinder to pass through. A connecting thread is provided at the end of the output rod of the hydraulic cylinder. The compression nut is threadedly connected to the connecting thread to fixedly connect the output rod of the hydraulic cylinder and the hydraulic cylinder joint together. Through holes are respectively provided on the two side arms of the hydraulic cylinder joint for the shear pin to pass through. The inserted end of the shear pin is limited by a limit snap ring 211. Each hydraulic cylinder is respectively connected to a hydraulic jacking synchronous control mechanism and is controlled by the hydraulic jacking synchronous control mechanism to perform synchronous lifting and lowering. The control can be carried out by using a hydraulic jacking synchronous control mechanism of the prior art, which will not be elaborated here.

[0035] In a preferred structure, each shear fork lifting arm and the hydraulic cylinder are movably connected up and down through a synchronous lifting vertical guiding device. The synchronous lifting vertical guiding device, also known as the jacking guiding mechanism, can be a guiding device composed of a sliding block and a sliding rail, or a guiding device composed of a guide post and a guide sleeve. In the present utility model, the following jacking guiding mechanism is preferably adopted. The jacking guiding mechanism includes vertical frames 241 located on both sides of the vacuum cabin. A vertical displacement guiding groove 242 is provided on the vertical frame in the vertical direction. The shear pin is slidably connected with the vertical displacement guiding groove. The length of the vertical displacement guiding groove needs to be greater than or equal to the opening stroke of each layer of the vacuum cabin. The number and height of the vertical displacement guiding grooves 242 match the number of sections of the shear fork lifting arm, and each section of the shear fork lifting arm is correspondingly equipped with a vertical displacement guiding groove.

[0036] The combined synchronous lifting system adopting this structure controls the actions of each hydraulic cylinder by a hydraulic jacking synchronous control mechanism, drives the upper covers of each vacuum cabin to lift and lower by the shear fork lifting arms, and the guide wheel assembly moves horizontally in the horizontal displacement guiding groove, absorbing the horizontal movement distance at the end of the fork-shaped arm and limiting the upper cover in the horizontal direction, greatly reducing the sway amount of the heating plate assembly in the horizontal direction. The fork arm pin of the jacking guiding mechanism moves up and down in the vertical displacement guiding groove to limit the movement direction of the fork-shaped arm in the vertical direction. The two work together to effectively prevent the heating plate assembly from being misaligned in the horizontal direction during the lifting and lowering process, ensuring the position accuracy of opening and closing the cover and the stability of the lifting of the heating plate assembly. More preferably, the extending rod of the hydraulic cylinder is slidably connected with the vertical displacement guiding groove through a guide wheel assembly 6. The fork arm pin 212 also serves as the guiding pin 62 of the guide wheel assembly of the synchronous lifting vertical guiding device, and the guiding pin sleeve 63 of the guide wheel assembly is fixedly connected to the end 241 of the fork-shaped arm. A guiding frame notch plug 245 is provided on the vertical displacement guiding groove to block the guiding bearing 61.

[0037] In the multi-stage laminator adopting the utility model, the heating plate assemblies constituting each vacuum chamber are all connected with the lifting ends of the scissor lifting arms through a horizontal displacement compensation device. One lifting end of a pair of scissor lifting arms is connected to the object to be lifted. The object to be lifted is connected to the lifting end at the corresponding height at the side of the scissor lifting arm, rather than at the top of the overall scissor lifting mechanism. Therefore, a scissor lifting mechanism can be equipped with multiple sections of scissor lifting arms according to the number of objects to be lifted, and thus has multiple lifting ends, and can lift multiple objects simultaneously. When specifically applied to a multi-layer multi-stage laminator, it can synchronously lift multi-layer laminators, truly realizing the synchronization of each layer of laminators. The multi-stage laminating main machines are controlled to synchronously lift through a jacking synchronization control mechanism, truly realizing large-scale linkage of multiple layers and multiple stages. Each hydraulic jacking mechanism is controlled by the same hydraulic jacking synchronization control mechanism. Therefore, it can open and close the cover synchronously.

[0038] In the utility model, guide wheel assemblies are arranged at the top ends of the scissor lifting arms and at the hinge points of two adjacent scissor lifting arms, and are horizontally movably connected with the horizontal displacement guiding grooves arranged on the heating plate assemblies through the guide wheel assemblies. The hinge points of the two scissor sub-arms are also vertically movably connected with the vertical displacement guiding grooves arranged on the vertical frame through the guide wheel assemblies, which can prevent the heating plate assemblies from shifting in the front-rear direction when opening and closing the cover, and can ensure the accuracy of opening and closing the cover. With the above structure, when multiple vacuum chambers are arranged, it can not only drive the vacuum chambers on the same layer to open and close the cover synchronously, but also drive the vacuum chambers on different layers to open and close the cover synchronously, truly realizing large-scale linkage of opening and closing the covers of multiple vacuum chambers on multiple layers.

[0039] To further increase the accuracy of opening and closing the cover, a cavity lifting guiding device 4 is provided to limit the horizontal movement of the cavity when the cavity is lifted. The cavity lifting guiding device includes guide wheels with two wheel shafts vertically arranged, simply referred to as right-angle guide wheels 41. The right-angle guide wheels are fixedly arranged on the upper cover 101 through right-angle guide wheel mounting frames 42. Usually, four right-angle guide wheels are arranged on the upper cover, and a pair of right-angle guide wheels are arranged on each of the left and right sides of the upper cover. A pair of right-angle guide wheels are arranged at the front and rear of the edge of the upper cover. Guide columns 43 are arranged at positions corresponding to the positions of the right-angle guide wheels, that is, two rectangular guide columns are respectively arranged on the left and right sides. The heating plate assembly is located between the four guide columns. Two of the guide wheels in the right-angle guide wheels are respectively in rolling connection with two perpendicular side surfaces of the guide columns. When the heating plate assembly shakes during the lifting process, the rollers arranged on the upper cover are in rolling connection with the corresponding side guide columns, and are guided by the guide columns to prevent the heating plate assembly from shaking in the front-rear, left-right directions. With this structure, since the heating plate assembly will be limited by the two vertically arranged guide wheels when it is offset, the offset amounts in its front-rear, left-right directions are all determined by the position error between the guide columns and the upper cover. Adjusting the position error can adjust the opening and closing accuracy of the upper cover.
