[0002] In the field of laminating technology, laminators are crucial machines for pressing multiple layers of material together. For example, in the production of photovoltaic modules, laminators press EVA, solar cells, tempered glass, and backing films (such as TPT and PET) into a rigid, integrated unit under high-temperature, vacuum conditions. In the production of composite panels like flooring, laminators heat and press the individual layers together to form a single unit.

[0003] In order to better adapt to the continuous changes of the curved surface of rigid curved laminated components and complete the lamination and transmission of curved components, our company has developed a soft press box. The soft press box is used to transmit and laminate the curved rigid laminated components. The soft press box is both a carrier for transmission and a cavity for lamination. Figure 1 As shown, the flexible press box includes an upper cover 510 and a lower box 520. The upper cover includes an elastic pressure member 5101 and its fixed support frame. The fixed support frame securely supports the elastic pressure member so that it can be unfolded to cover the laminated assembly. The lower box 520 includes an elastic support member 5201 and an elastic support member fixed support frame. The elastic support member 5201 secures the support frame to securely support the elastic support member so that it can be unfolded to support the laminated assembly. When the upper cover and lower box are fastened together, they form a sealed chamber, which is locked by a locking device 550 to accommodate the laminated assembly. To achieve full automation, the flexible press box is equipped with a laminating host of the present invention, which completes the heating and pressurization of the laminated assembly at the laminating host.

[0045] The following examples are used to further describe the present invention. 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 orientation shown illustrates the positions of the components.

[0046] The laminating machine main unit 300 of the present invention is used to evacuate the soft press box and heat the components in the soft press box to complete the lamination and curing of the rigid curved surface components. Figure 2-10 As shown, the laminator mainframe includes a mainframe 350 , a heating box 310 , a mainframe vacuum system 320 , and a heating device 330 .

[0047] The heating box 310 preferably has the following structure, including a sealed box body 311. A soft pressure box inlet and a soft pressure box outlet are respectively provided on the front and rear sides of the box body. Door panels are respectively provided at the soft pressure box inlet and outlet. One end of the door panel is hingedly connected to the box body via a hinge 3134. A door panel pin 3131 is provided at the end of the door panel opposite the hinge. A door panel opening and closing device 33 drives the door panel to open and close the soft pressure box inlet and / or the soft pressure box outlet. The door panel opening and closing device includes a door panel cylinder 3133 and a door panel fisheye joint 3132. The output end of the door panel cylinder is connected to one end of the door panel fisheye joint, and the other end of the door panel fisheye joint is rotatably connected to the door panel pin 3131. The door panel cylinder 3133 is hingedly connected to a door panel cylinder fixing base 3135 via a door panel cylinder pin 3136. The door panel cylinder fixing base is fixedly connected to the main frame. When the plenum is ready to enter, the door cylinder at the inlet activates, opening the door. Once inside, the cylinder activates, closing the door. When the plenum is ready to exit, the cylinder at the outlet activates, opening the door. Once the plenum is completely removed, the outlet door closes. A heating box allows for closed heating of the plenum, fully utilizing the heat, improving heating efficiency, reducing heating time, and saving energy.

[0048] The main unit vacuum system 320 is connected to the vacuum structure of the plenum chamber, connecting the vacuum pump to the chamber's interior, evacuating the chamber and breaking the vacuum within the chamber and piping. It includes a vacuum piping docking device, a vacuum control device, and a vacuum breaking device. The vacuum piping docking device connects the plenum chamber to the vacuum device, the vacuum control device and vacuum pump evacuate the chamber, and the vacuum breaking device breaks the vacuum within the chamber and piping.

[0049] The vacuum pipe docking device includes a plenum-side vacuum docking flange 3211, a mainframe-side vacuum docking flange 3221, and a vacuum docking drive. The vacuum docking drive typically utilizes a pneumatic or electric cylinder. The mainframe-side vacuum docking flange has an O-ring groove A on the side opposite the plenum-side vacuum docking flange. An O-ring A is secured within this groove. The other side of the groove is secured to a vacuum docking frame 3225. The vacuum docking frame 3225 is connected to the vacuum docking drive, which is secured to a second vacuum docking base 3226. The vacuum docking frame 3225 is slidably connected to a linear guide rail 3227, which is in turn connected to a first vacuum docking base 3228. The mainframe-side vacuum docking flange is used to dock with the plenum-side vacuum docking flange of the plenum-side vacuum docking flange. One end of the vacuum hose 32210 is sealed and connected to the vacuum through-hole provided on the main unit's vacuum docking flange 3221. The other end is sealed and connected to the vacuum tube 3229. The other end of the vacuum tube 3229 is connected to the vacuum valve 32211. The other end of the vacuum valve 32211 is connected to the vacuum manifold 32213 via the vacuum branch pipe 32212. The vacuum manifold 32213 can be equipped with multiple vacuum branch pipes 32212 as needed to connect different plenum chambers. One end of the vacuum pump connecting pipe 32214 is connected to the vacuum manifold 32213 and the other end is connected to the vacuum pump 32215.

[0050] The vacuum control device 323 preferably adopts the following structure, including a pneumatic pilot vacuum valve 32318, a pilot gas docking flange A32317, a pilot gas docking flange B3232 and a pilot gas docking drive device for driving the pilot gas docking flanges A and B to dock. The air exhaust inlet and air exhaust outlet of the pneumatic pilot vacuum valve 32318 are respectively connected to the cavity connecting pipe 3214 and the vacuum docking flange on the soft pressure box side, the pilot gas inlet is connected to the pilot gas docking flange A32317, and the pneumatic pilot vacuum valve 32318 is connected to the pilot gas docking flange A32317 through the pilot gas pipe 32319. Typically, a pneumatic cylinder or electric cylinder B serves as the pilot air docking drive 3235. An O-ring groove B3231 is defined on the side of pilot air docking flange B3232 opposite pilot air docking flange A. An O-ring B3233 is secured within O-ring groove B. The other side is fixedly connected to the pilot docking frame 3234. The pilot docking frame 3234 is connected to the pneumatic cylinder or electric cylinder B serving as the pilot air docking drive. The pneumatic cylinder or electric cylinder B3235 is secured to the second pilot docking base 32316. The pilot docking frame 3234 is slidably connected to the second linear guide rail 32314 secured to the first pilot docking base 32315. The length of linear guide rail 2 32314 is perpendicular to the end face of pilot mating flange A. When the pneumatic pilot vacuum valve 32318 needs to be opened, the pilot gas docking drive pushes the pilot docking frame 32314 toward pilot gas docking flange A, thereby pushing pilot gas docking flange B toward pilot gas docking flange A for docking. O-ring B seals pilot gas docking flange A 32317 and pilot gas docking flange B 3232. An inflation hose 3236 compensates for the movement of pilot gas docking flange B 3232. One end of inflation hose 3236 is connected to pilot gas docking flange B 3232, and the other end is connected to inflation pipe 3237. The other end of inflation pipe 3237 is connected to on-off valve 32310. The other end of on-off valve 32310 is sealedly connected to inflation manifold 32313 via inflation branch pipe 32311. The inflation manifold 32313 can be installed with multiple inflation branch pipes 32311 as needed, and the gas source enters from the inflation manifold interface 32312.

[0051] The vacuum breaker device preferably adopts the following structure, including a vacuum breaker valve 3242, a vent valve 3244, a vacuum pipe joint 3241, and an inflation pipe joint 3243. One end of the inflation pipe joint 3243 is connected to the inflation pipe 3237, and the other end is connected to the vent valve 3244. The vacuum breaker valve is connected to the vacuum pipe 3229 via the vacuum pipe joint 3241. When the pneumatic pilot vacuum valve 32318 needs to be opened, after the pilot gas docking flange A 32317 and the pilot gas docking flange B 3232 are docked, the switch valve 32310 is opened, and the compressed air passes through the switch valve 32310, the pilot gas docking flange B 3232, and the pilot gas pipe 32319 and then enters the pneumatic pilot vacuum valve 32318, thereby closing the pneumatic pilot vacuum valve 32318. 18 is opened. When the pneumatic pilot vacuum valve 32318 needs to be closed, first close the switch valve 32310 to stop the air supply, and then open the air release valve 3244 to discharge the compressed air in the pilot air pipe 32319. Since there is no positive pressure in the pilot air pipe 32319, the pneumatic pilot vacuum valve 32318 is closed at this time, and then the pilot air docking drive device 3235 drives the pilot air docking flange B3232 to separate from the pilot air docking flange A32317.

[0052] The vacuum control device of the present invention uses a pneumatic pilot valve to control the opening and closing of the vacuum device. The pneumatic pilot valve can be opened under positive pressure and closed when positive pressure is lost. Therefore, the connection between the vacuum pipeline and the soft pressure box is completely controlled by a mechanical device. Compared with the use of electronic devices such as solenoid valves to control the connection between the soft pressure box and the vacuum device, the control valve is not affected by high temperatures and can achieve docking under high temperatures. The entire soft pressure box does not require power, so there is no need to install wires. The soft pressure box can be moved to any position without being constrained by wires. It starts when positive pressure is applied and automatically closes when positive pressure is not applied, providing reliable vacuum start and stop. The vacuum control device of the present invention is provided with a bleed valve 3244. When the soft pressure box is vacuumed and needs to be removed, the bleed valve 3244 is used to break the residual positive pressure in the air supply pipeline before it is removed. This prevents aeration when the pneumatic pilot flange A and the pneumatic pilot flange B are removed while the air supply pipeline is still under positive pressure, thus eliminating safety hazards.

[0053] The host vacuum system 320 that uses the above-mentioned flange combined with the O-ring to achieve sealed docking can realize dynamic docking between the soft pressure box and the vacuum device and the inflation device, and can inflate and break the vacuum of the online soft pressure box, thereby realizing the automation of the soft pressure box's vacuuming, and the structure is simple and reliable.

[0054] A conical docking structure with a conical body and an O-ring can also be used for docking. The conical docking structure includes a conical hole docking seat 3216 and a conical docking joint 3217. The conical hole docking seat includes a conical hole seat body 32161 and a conical hole docking seat vacuum joint 32162. The conical hole docking seat vacuum joint 32162 and the conical hole seat body are fixedly connected in an integral manner. The conical hole 32163 of the conical hole seat body is sealed and connected to one end of the conical hole docking seat vacuum joint, and its small aperture end is connected to the conical hole docking seat vacuum joint. The other end of the conical hole docking seat vacuum joint is connected to the pneumatic pilot vacuum valve 32318. The conical docking joint 3217 includes a conical head 32171 and a conical head connecting flange 32172. Through holes 32173 are provided in the conical head connecting flange and the conical head. The taper and diameter of the conical head are respectively adapted to the taper and diameter of the conical hole, and the two are plug-connected. The conical head is connected to the vacuum docking drive device. The two plug-in docking structures described above enable automated docking. Alternatively, a direct threaded connection can be used for sealing. The plenum-side vacuum docking flange and the plenum-side tapered docking seat 3216 constitute the plenum-side vacuum docking structure, while the mainframe-side vacuum docking flange and the mainframe-side tapered docking joint 3217 constitute the mainframe-side vacuum docking structure. Pilot gas docking flange A and the pilot gas tapered docking seat 3216 are referred to as pilot gas needle true docking structure A, while pilot gas docking flange B and the pilot gas tapered docking joint 3217 are referred to as pilot gas docking structure B.

[0055] When vacuum docking is required, the pneumatic or electric cylinder A, acting as the vacuum docking drive, pushes the vacuum docking frame toward the vacuum docking flange on the plenum side, thereby pushing the vacuum docking flange on the main unit close to the vacuum docking flange on the plenum side for docking. The vacuum docking flange on the main unit and the plenum side are sealed by O-ring A. The vacuum hose compensates for the movement of the vacuum docking flange on the plenum side.

[0056] Once the main unit vacuum docking flange and the plenum chamber vacuum docking flange are docked, the pneumatic pilot vacuum valve 32318 opens, followed by the vacuum valve 32211, and the vacuum pump 32215 begins evacuating the interior of the plenum chamber 500. When the evacuation is complete, the pneumatic pilot vacuum valve 32318 is first closed to ensure the vacuum level within the plenum chamber. Then, the vacuum valve 32211 is closed, and the vacuum breaker valve 3242 is opened to break the vacuum in the pipeline. The vacuum docking drive then pulls the main unit vacuum docking flange 3221 back into position, allowing the plenum chamber 500 to be removed for the next step. Typically, the plenum chamber vacuum docking flange, pneumatic pilot valve, and pneumatic pilot docking flange A are all connected to the plenum chamber via pipe 3214. Movement of the plenum chamber drives the movement of the plenum chamber vacuum docking flange, pneumatic pilot valve, and pneumatic pilot docking flange A.

[0057] When the vacuum in the plenum chamber 500 needs to be broken, the vacuum docking drive 3224 pushes the vacuum docking flange on the plenum chamber side to mate with the vacuum docking flange on the air side. Then, the inflator is used to inflate the plenum chamber, opening the pneumatic pilot vacuum valve 32318. Then, the vacuum breaker valve is opened. Air passes through the vacuum breaker valve, enters the pneumatic pilot vacuum valve, and finally enters the plenum chamber 500, breaking the vacuum within the plenum chamber. This device breaks the vacuum within the plenum chamber, allowing outside air to enter the plenum chamber through the vacuum breaker valve. This eliminates the need for an additional inflator, resulting in a simple structure and low cost.

[0058] like Figure 2-5 As shown, the heating device 330 includes a heater 331, which can be an electric heating rod, heating pipe, heating plate, etc. The heater is fixed to the laminator's main frame 350 and is used to heat the space through which the flexible press passes, thereby heating the flexible press. The number of heaters 331 can be determined based on the size of the curved flexible press 500 and the power of the heaters 331 themselves, to provide the required heat source for the laminator.

[0059] It is best to provide an air disturbance device 332 so that the heat can be fully utilized and the heating efficiency can be improved. The heating body is distributed in the heating box 310. The air disturbance device disturbs the air in the heating box cavity, causing it to flow in the heating box. Usually, the air disturbance device adopts a fan 3321, and the fan motor 3322 is fixed to the laminator main frame 350. The air outlet of the fan faces the heating box cavity. Multiple fans are provided, and the air outlets of the fans are evenly provided on the side walls on both sides and / or the side walls at the end of the heating box body. The main vacuum system can be located in its entirety or partially in the heating box. A pipe interface is provided on the heating box for the vacuum pipe to pass through. When it is partially located in the heating box, at least the vacuum pipe docking device is provided in the heating box, and preferably the vacuum control device is also provided in the heating box to ensure good docking and sealing of the entire device. This allows the main vacuum system to be smoothly docked with the soft pressure box. To reduce the overall size of the heating box and conserve heating energy, a main unit vacuum system protection box 370, connected to the heating box, is located on the outside of the heating box where it meets the soft pressure box. The main unit vacuum system is housed within the main unit vacuum system protection box. Vacuum pipe connections are located on the main unit vacuum system protection box.

[0060] In order to facilitate the automated transmission of the soft pressure box, a host track and a host drive device are also provided to drive the soft pressure box to move, thereby completing the automated transmission and transfer of the laminated components.

[0061] The main engine track 314 is located inside the heating box and is fixedly mounted on the main engine frame. Usually, two main engine tracks 314 are arranged in parallel, extending from the inlet to the outlet of the soft pressure box. The upper surface of the main engine track is higher than the bottom of the inlet and outlet of the soft pressure box, and is used to receive the soft pressure box 500. It is connected in a rolling manner with the track wheel 5012 fixedly mounted on the lower box base 501 of the soft pressure box 500. The soft pressure box moves on the main engine track under the drive of the main engine drive device.

[0062] The main engine driving device 315 preferably adopts the following structure including a main engine chain transmission device and a main engine linkage rod 3151. The main engine chain transmission device includes a main engine driving shaft 3152 and a main engine driven shaft 3153. Main engine driving sprockets 3154 are respectively provided at both ends of the main engine driving shaft, and main engine driven sprockets 3155 are respectively provided at both ends of the main engine driven shaft. The main engine driving shaft and the main engine driven shaft are respectively rotatably provided on the main engine frame. The main engine driving shaft is connected to the main engine transmission motor 3156. The length direction of the main engine driving shaft and the main engine driven shaft is perpendicular to the length direction of the main engine track. They are respectively located at the two ends of the main engine track, and the corresponding main engine driving sprockets and main engine driven sprockets are connected by a main engine chain 3157. Specifically, the host transmission motor 3156 is fixed on the main frame 350, and the two host driving sprockets 3154 are respectively fixed at the two ends of the host driving shaft 3152, and the host driving shaft 3152 is connected to the host transmission motor 3156; the two host driven sprockets 3155 are respectively fixed at the two ends of the host driven shaft 3153, and the host driven shaft 3153 is rotatably connected to the main frame 350. The two host chains 3157 are respectively installed on the sprockets of the host driving shaft and the host driven shaft. A plurality of host linkage rods 3151 are fixed in parallel, and their two ends are respectively fixedly connected to the host chains 3157 at the corresponding ends. The rotation of the host transmission motor 3156 drives the sprocket to rotate, thereby driving the host chain 3157 to transmit, thereby driving the host linkage rod 3151 installed on the chain to move, and the host linkage rod 3151 is in contact with the moving thrust rod provided on the soft pressure box. By pushing the moving thrust rod, the soft pressure box 500 is pushed along the host track from the soft pressure box inlet side to the soft pressure box outlet side.

[0063] The main drive device of the present invention structure drives the soft pressure box to move on the main track, which has the following advantages: in the present invention, the main track is connected to the roller set at the bottom of the soft pressure box by rolling, and the chain transmission device drives the main link rod to move, and the main link rod pushes the soft pressure box forward. A relatively large soft pressure box can be pushed with a smaller force, and the chain transmission device provides the power for the soft press to move forward. The main track supports and guides the forward direction of the soft press. Therefore, the soft pressure box runs smoothly, and can smoothly push the relatively heavy soft pressure box composed of metal components to the desired position, and can realize the positioning and transmission of the stacked components.

[0064] Preferably, a soft pressure box clamping and positioning device 340 and a soft pressure box host position detection device are provided, so that the soft pressure box stops at a fixed position after entering the heating box, so as to facilitate docking with the host real control system.

[0065] The pliable pressure box clamping and positioning device includes a limit plate 341, a limit shaft 342, a force transmission rod 343, and a limit plate rotation drive 344. The limit shaft 342 secures the limit plate 341 at one end and the force transmission rod 343 at the other end. One end of a clamping fisheye joint 345 is rotatably connected to the other end of the force transmission rod 343 via a clamping pin 346. A clamping cylinder is typically used as the limit plate rotation drive 344. One end of the limit plate rotation drive 344 is connected to the other end of the clamping fisheye joint 345. The clamping cylinder seat is rotatably connected to the clamping cylinder fixing seat 347 via a clamping cylinder pin 348. When the clamping cylinder rod extends or retracts, it rotates the limit shaft 342, thereby rotating the limit plate 341. When the pliable pressure box clamping device is in a standby state, the limit plate is in a horizontal position. Two flex press box clamping and positioning devices are located on the inner or outer sides of the two main machine tracks 314. The limit plates of the four flex press box clamping and positioning devices are at the same height, and the spacing between the tracks matches the length of the flex press box. Specifically, a limit plate 341 is symmetrically arranged on either side of the laminator's inlet and outlet, for a total of four limit plates. Before the curved flex press box 500 enters the laminator, the limit plates 341 at both the inlet and outlet are horizontal. Once the curved flex press box 500 enters the laminator and reaches the predetermined position, it is positioned between the four limit plates. The rotational drive devices of each limit plate are activated, causing the limit plates 341 at both the inlet and outlet to rotate toward the curved flex press box 500, thereby clamping the curved flex press box 500 between the four limit plates and securing its position. At least the limit plates are completely located within the heating chamber.

[0066] In order to ensure that the soft pressure box stops accurately at the set position, a soft pressure box position detection device is provided. When the soft pressure box enters the position between the four limit plates, the soft pressure box position detection device sends a signal, the host drive device 315 stops driving, and the limit plate rotation drive device drives the limit plates to move, clamping the soft pressure box.

[0067] The working process of the laminating machine main unit is as follows: when the soft pressing box 500 is ready to enter the soft pressing laminating machine main unit, the door panel at the inlet end of the heating box is opened by the drive of the door panel opening and closing device, the main unit transmission motor 3156 is started, driving the main unit chain 3157 to run, driving the main unit linkage rod 3151 to push the soft pressing box 500 forward, and after the soft pressing box 500 completely enters the soft pressing laminating machine main unit, the door panel is closed by the drive of the door panel opening and closing device. After the soft pressing box 500 moves to the docking position of the main unit vacuum system 320, the four limit plates 421 are driven by the clamping cylinder to rotate toward the soft pressing box 500, clamping the soft pressing box between the four limit plates. The soft pressure box 500 is fixed between the boards. At this time, the vacuum docking drive device of the host vacuum system 320 is started to drive the vacuum docking flange on the host side to dock with the vacuum docking flange on the soft pressure box side. The pilot gas docking flange drive device drives the pilot gas docking flange B to move toward the pilot gas docking flange A for docking. The inflation device is inflated to make the pneumatic pilot vacuum valve conductive, the vacuum device is turned on, the soft pressure box 500 is evacuated, and the hot air in the heating box heats the soft pressure box as a whole. The components begin to be laminated. After the vacuuming is completed and the lamination is cured, the vacuum breaking device of the host vacuum system 320 breaks the vacuum of the soft pressure box 500. After all the actions of the main vacuum system 320 are completed, the main vacuum system 320 is disengaged from the soft press box 500, and the four limit plates 421 rotate in the opposite direction to release the fixation of the soft press box 500. The main transmission motor is started again, driving the main linkage rod 3151 to push the soft press box 500 forward. Before the soft press box 500 exits the laminator main body, the exit door panel opens. After the soft press box 500 is completely out, the door panel closes.

[0068] When heating is required, the heater starts heating and the fan starts rotating to evenly distribute the heat in the cavity.

[0069] A return device may also be provided to transport the soft pressing box from the discharge end of the heating box back to the feed end of the heating box.

[0070] The return device includes a return frame 910 and a return transmission device 920. The return transmission device 920 includes a return track 921 and a return chain transmission device. The return main drive shaft and the return slave drive shaft are rotatably arranged on the return frame, and the two are arranged parallel to each other along the running direction of the soft pressure box. The return chain is connected to the return main drive shaft and the return slave drive shaft through a return sprocket. The running direction of the return chain is parallel to the length direction of the return track. A return linkage rod is provided on the return chain. The length direction of the return linkage rod is perpendicular to the return chain. The return drive device preferably adopts a motor reducer. The output end of the return drive device is connected to the return main drive shaft. The return drive device drives the return main drive shaft to rotate, driving the return chain to run, so that the return linkage rod moves along the running direction of the soft pressure box, thereby pushing the soft pressure box to move along the return track. The return frame is usually located below the main frame. The return track and the return chain can be respectively opposite to the loading and unloading track and the loading and unloading chain of the loading and unloading platform.

[0071] like Figure 2-5 As shown, the laminating machine main unit of the present invention is preferably multi-layered, and the laminating machines of each layer share a heating box. On the box body of the heating box, a feed port is opened corresponding to the position of each laminating machine main unit, and each feed port is provided with a door panel and a door panel opening and closing device. A discharge port is opened corresponding to the position of each laminating machine main unit, and a door panel and a door panel opening and closing device are provided at the discharge port. The main unit track and main unit drive device 315 of each layer are adapted to the height of the feed port and discharge port of the corresponding layer, so that the soft pressing boxes on each layer can smoothly enter from the feed port along the main unit track and move out from the discharge port. The main unit vacuum system of each layer of the laminating machine main unit is fixedly arranged outside the box, connected to the vacuum pump through its own vacuum manifold, and connected to the air pump through the air manifold. The spaces of each layer in the soft pressing laminating machine main unit can be interconnected, so as to better ensure uniform heat distribution, or each layer can be made into a structure with an independent space, and each layer of the laminating machine main unit is provided with an independently separated cavity.

[0072] Figure 2 、 Figure 4 and Figure 5 In the illustrated embodiment, six layers of laminating machines are provided, stacked one above the other. Each layer is equipped with four fans 3321 as air disturbance devices, which disturb the air within the heating chamber. The air flows within the heating chamber, thereby evenly distributing the heat of the heating elements 331 throughout the chamber. Each layer is equipped with eight heating elements 331. The number of fans 3321 is determined based on the principle of ensuring a more even distribution of heat from the heating elements 332.

[0073] The main frame 1 of the soft pressing laminator shown in the figure is provided with a heating box. The cavity of the heating box is a large chamber. There are 6 layers of laminating main machines in the cavity of the heating box. An insulation layer 301 is installed on the outside of the chamber to prevent the heat in the chamber from leaking out.

[0074] When a multi-layer laminating machine is set up, a corresponding number of soft pressing box clamping and positioning devices are set on both sides of the inlet and outlet of the heating box, and the limit plates on both sides of the heating box are arranged symmetrically, that is, 4 limit plates per layer.

[0075] Heating, pressurizing, vacuuming and heating and holding pressure can be completed by two laminator hosts. After preheating and vacuuming are completed in the cavity of the laminator host one, the components enter the cavity of the laminator host two to complete the lamination and curing.

[0076] A transition section is provided between the first and second laminator units, with a heater mounted on the transition section's frame. When the laminator is multi-layered, each transition section's frame is equipped with a transition section track that docks with the flexible press box track. The structures of the first and second laminator units are identical.

[0077] When the laminator main unit is set with two cavities, the working process is as follows: after the soft pressing box completes preheating and vacuuming in the first cavity of the laminator main unit, it enters the second cavity of the press main unit to complete the lamination and curing of the components. After the component lamination is completed, the second cavity of the laminator main unit pushes the soft pressing box out.

[0078] The so-called docking in the present invention means that the input and output ends of the two chains are opposite to each other, and the entry and removal ends of the two tracks are opposite to each other, so that the soft pressure box can be transferred from one chain to another chain, or from one track to another track.

[0079] In the present invention, the transmission device of the soft pressure box adopts the structure of track, chain transmission device and linkage rod. The chain transmission device drives the linkage rod to run, and the linkage rod pushes the soft pressure box forward on the track. The advantages of adopting this structure are: first, the track can support the soft pressure box and guide the forward direction of the soft pressure box, and the chain transmission device provides power for the forward movement of the soft pressure box. The combination of the two can push the heavy soft pressure box forward smoothly, and each section of the chain is rigid, so it will not stretch and deform due to resistance. Therefore, after the linkage rod is set, the position will not change due to the deformation of the chains on both sides, and the force direction is consistent. Second, each The unit is independently provided with a chain transmission device to transmit the soft pressure box. The soft pressure box can be moved at any time as needed without being restricted by other units. The purely mechanical structure can be well transmitted in the high-temperature box without high-temperature deformation. Thirdly, under normal circumstances, in order to achieve good sealing and not deform under pressure at high temperatures, the box body of the soft pressure box is made of metal components, which is relatively heavy. A soft pressure box can weigh several hundred pounds, so that the force of the transmission device is relatively concentrated. The soft pressure box transmission device of the structure of the utility model is adopted, and the soft pressure box is gravity-supported by the track. The chain transmission device only needs to overcome the friction between the track and the track wheel. Therefore, the entire transmission device does not deform.
