Description

Technical Field

[0001] The utility model belongs to the technical field of laminators, and particularly relates to a laminator for pressing and curing rigid curved surface components. Background Art

[0002] In the technical field of laminators, a laminator is a very important mechanical device for pressing multiple layers of materials together. For example, when producing photovoltaic modules, the laminator presses EVA, solar cells, tempered glass, and backsheets (materials such as TPT and PET) into a rigid whole under high-temperature and vacuum conditions. When producing composite boards such as floors, it is necessary to heat and press each layer of the board into a whole through a laminator.

[0003] In the prior art, when producing rigid curved surface components, a fixed mold is usually used to press the components. The shape of the pressing surface of the mold is the same as the shape of the surface of the curved surface component. The component is placed in the mold, and the upper and lower molds are used for laminating under high-temperature and vacuum conditions. When using a laminator with such a structure to press curved surface components, there are the following deficiencies: 1. Limited by the curvature or shape of the component, a mold of one model can only press one type of component. If the component changes slightly, the corresponding mold needs to be replaced; 2. The shape of the mold surface needs to match the shape of the component pressing surface very well, otherwise it is easy to cause damage to the component; 3. When laminating, because the mold is in direct contact with the component, it needs to be made of very good heat-conducting materials so that the temperature can be quickly and efficiently transferred to the component. This results in high manufacturing costs of the mold and low production efficiency. Summary of the Utility Model

[0075] The present utility model will be further described in detail below 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. For the convenience of narration, the present utility model will be described according to Figure 1 the positions between the components in the shown orientation.

[0076] The present utility model laminates a rigid curved surface component by the following method. Place the curved surface component into a vacuum sealing cavity formed by an upper silicone plate and a lower silicone plate, which is located between the upper silicone plate and the lower silicone plate. Evacuate the vacuum sealing cavity to reach a predetermined vacuum degree and make the upper silicone plate and the lower silicone plate closely adhere to the curved surface component. Utilize the pressure difference inside and outside the upper silicone plate and the lower silicone plate to apply pressure to the curved surface component to reach the predetermined pressure. When evacuating the vacuum, the vacuum cavity can be heated to reach the curing temperature. By adopting the above method, since the upper silicone plate and the lower silicone plate are flexible, when acting on the curved surface component, they will conform to the shape of the component under the elastic action. Therefore, any curved surface shape including flat components can be pressed, and the conformity with the surface shape of the component is good. Thus, the versatility is good, and there is no requirement for the conformity between the shape of the pressing head of the mold and the curved surface of the component, reducing the processing difficulty.

[0077] Specifically, a laminator with the following structure can be used to complete the lamination and curing of the curved surface component.

[0078] Such as Figures 1 - 32As shown, the laminator of the utility model includes a laminating box for curved surface soft pressing (hereinafter referred to as soft pressing box) 500 and a laminating machine main unit for soft pressing (hereinafter referred to as laminating machine main unit) 300.

The elastic pressure member and the elastic pressure member fixed support frame constitute an upper cover, and the elastic supporting member and the elastic supporting member fixed support frame constitute a lower box. When the upper cover and the lower box are closed, a sealed cavity for accommodating a rigid curved surface component is called a soft pressing box cavity. The space between the elastic pressure member and the elastic supporting member is used to accommodate the component. A vacuum structure is provided on the soft pressing box, and the vacuum structure is used to connect the soft pressing box cavity and the main unit vacuum pumping system. The laminating machine main unit includes a main unit vacuum system and a heating system. The main unit vacuum system is equipped with a vacuum pipe docking device, a vacuum breaking device and a vacuum pumping control device. The vacuum pipe docking device is used to connect the vacuum structure and vacuum pump of the soft pressing box to realize vacuum pumping of the soft pressing box cavity, and the heating system heats the soft pressing box. The soft press box is used to load and remove components when the cover is opened, and is used to evacuate and heat components when the cover is closed. The components to be laminated are pre-loaded into the soft press box cavity and the cover is closed and locked. The soft press box with components is placed in the soft pressing laminator main machine. The soft pressing laminator main machine evacuates and heats the soft press box. The components are vacuumed and heated in the soft press box. Then the soft press box is removed from the soft pressing laminator main machine. The soft press box is opened to remove the laminated components to complete the packaging of the components. In the laminator adopting the above structure, the soft press box and the laminator main machine are separately arranged. After the components are loaded into the soft press box, they are evacuated and heated by the laminator main machine. The time for each soft press box to enter and exit the laminator main machine is consistent, and independent vacuum and heating time control can be achieved. After the components enter the laminating main machine, they can be evacuated and heated without waiting. Therefore, the vacuum and heating time of the components are consistent, the process is consistent, and the quality control of each component is convenient and reliable. With the laminating machine of the utility model, the pressure-applying parts and the supporting parts of the flexible pressure box are both elastic parts, so they can deform freely with the laminated curved surface components, and there is no need to specially manufacture molds of corresponding shapes. The versatility is good, and the pressure on the upper and lower surfaces of the components depends on the pressure difference between the internal vacuum and the external atmospheric pressure, so pressure uniformity can be achieved.

[0079] To facilitate automated production, the laminator is provided with a loading table 100 and an unloading table 600. The loading table can realize automatic opening, closing and locking of the soft press box, and the soft press box with components is transferred to the laminator main body. The unloading table receives the soft press box removed from the laminator main body, and automatically unlocks and opens the soft press box.

[0080] Further, when the main body of the laminator has multiple layers, a lift type feeding table 200 is arranged between the loading table and the main body of the laminator. The lift type feeding table receives the flexible pressing box containing components removed from the loading table, raises and lowers the flexible pressing box containing components to different heights. A lift type discharging table 400 is arranged between the main body of the laminator and the discharging table. The lift type feeding table is docked with the main body of the laminator at different heights to transfer the flexible pressing box into the main body of the laminator at different heights. The lift type discharging table is docked with the laminator at different heights, receives the flexible pressing box removed from the main body of the laminator at different heights, and conveys it to the discharging table to take out the laminated components from the flexible pressing box.

[0081] Such as Figures 4 - 14As shown, the soft pressing box 500 of the present utility model preferably adopts the following structure, including an upper cover 510, a lower box 520, an upper cover lifting device 530, a vacuum structure 540, and a locking device 550. The upper cover includes an upper silicone plate 5101 as an elastic pressing member, an upper cover upper pressing frame 5102, and an upper cover lower pressing frame 5103. The upper silicone plate is fixedly arranged between the upper cover upper pressing frame and the upper cover lower pressing frame. A first silicone strip 5106 is embedded in the lower end surface of the upper cover upper pressing frame 5102, and a second silicone strip 5104 and a third silicone strip 5105 are respectively embedded in the upper and lower sides of the upper cover lower pressing frame 5103. The upper cover upper pressing frame and the upper cover lower pressing frame clamp the upper silicone plate 5101 through the first silicone strip on the upper cover upper pressing frame and the second silicone strip on the upper cover lower pressing frame to ensure the sealing performance. The upper cover lifting device 530 includes a lifting arm 532. The upper cover upper pressing frame is fixedly connected to the lower surface of one end of the lifting arm 532 through its upper surface. A thrust shaft 531 is arranged at the end of the other end of the lifting arm. One end of the thrust shaft is rotatably connected to the lifting arm, and the other end is located outside the lifting arm for receiving the action of an external force to open the lifting arm. Usually, two lifting arms are provided. The lower box 520 includes a lower silicone plate 5201 as an elastic supporting member, a lower box upper pressing frame 5202, and a lower box lower pressing frame 5203. The lower silicone plate is fixedly arranged between the lower box upper pressing frame and the lower box lower pressing frame and is hermetically connected through silicone strips. Usually, two silicone strips are arranged on the upper side of the lower box lower pressing frame, namely a fourth silicone strip 5204 and a fifth silicone strip 5205. The lower silicone plate 5201 is clamped by the fourth silicone strip 5204, the fifth silicone strip 5205 fixed on the lower box lower pressing frame 5203, and the lower box upper pressing frame 5202 to ensure the sealing performance. The lower box lower pressing frame is fixedly arranged on the lower box base 501 and is supported and fixed by the lower box base. The lower box base 501 preferably includes a base frame body 5013 and a plurality of columns 5014. The columns are distributed above the base frame body, and the lower box lower pressing frame 5203 is fixed on the plurality of columns 5014. Through the support of the columns, the distance between the lower silicone plate 5201 and the base frame body 5013 in the horizontal state is greater than the maximum height of the laminated component. In this way, when a curved surface component is placed on the lower silicone plate, the lower silicone plate can obtain a space to extend downward due to the gravity of the component. The elastic pressing member and the elastic supporting member can also adopt elastic cloth such as latex. The upper cover upper pressing frame and the upper cover lower pressing frame constitute a fixed support frame for the elastic pressing member, and the lower box upper pressing frame and the lower box lower pressing frame constitute a fixed support frame for the elastic supporting member. The silicone strips for sealing, such as the first silicone strip, the second silicone strip, the third silicone strip, the fourth silicone strip, and the fifth silicone strip, can also adopt other sealing members.

[0082] A tipping bracket 533 is provided on the lower box base. One end of the lifting arm 532, where a thrust shaft 531 is provided, is rotatably connected to the tipping bracket 533 through a tipping shaft 534. The tipping shaft is located between the thrust shaft and the upper cover pressing frame. During automatic operation, the thrust shaft is used to receive an external force pushing from top to bottom. Under the action of the external force, the thrust shaft drives the upper cover to tip and open the upper cover of the soft pressing box. When two lifting arms are provided, one thrust shaft can connect two lifting arms, or one thrust shaft can be provided for each lifting arm. When the upper cover and the lower box are closed, the lower pressing frame of the upper cover and the upper pressing frame of the lower box are hermetically connected through a silicone strip 5106, and the upper cover and the lower box form a sealed cavity for accommodating the rigid curved surface assembly.

[0083] The locking device 550 makes the upper cover and the lower box closely fit together after the soft pressing box is closed, that is, before and after the soft pressing box is opened and closed, so as to ensure the sealing between the two silicone plates, that is, the sealing of the sealed cavity formed by the upper cover and the lower box. At least a pair of locking devices are provided on two opposite edges of the lower box base. The locking device 550 preferably adopts the following structure:

[0084] Structure 1: As Figure 7 and Figure 11 、 Figure 12 shown, the locking device is a tensioning device, including a tensioning support 5501, a tension spring 5505 and a tensioning rod 5503. The tensioning support is fixed on the edge of the lower box base. The lower end of the tensioning rod is rotatably connected to the tensioning support through a tensioning rotating shaft 5502. The upper end is provided with a pressure head 5510, and the pressure head is arranged towards the upper cover. A tension spring pin 5504 is fixed on the tensioning support. One end of the tension spring is connected to the tension spring pin, and the other end is connected to the end of the tensioning rod 5503 where the pressure head is provided. A roller 5507 is rotatably connected to the tensioning rod 5503 through a rolling pin 5506. Relying on the tension of the tension spring, the pressure head presses above the upper cover, and the upper cover and the lower box are closely fitted together. A force-bearing adjustment pad 5530 is fixed on the outer side of the lower end of the tensioning rod. The tensioning rotating shaft is located between the pressure head and the force-bearing adjustment pad. During automatic operation, relying on the external force to push the force-bearing adjustment pad, the tensioning rod 5503 rotates around the tensioning rotating shaft 5502, thereby releasing the state where the upper cover and the lower box are closely fitted. The end of the tensioning rod where the force-bearing adjustment pad is provided serves as the switch of the locking device. With the above-mentioned locking device, when opening the cover, only an external force needs to be applied to the force-bearing adjustment pad end to open the soft pressing box. When closing the cover, only the external force needs to be removed, and the upper cover will automatically snap shut. Therefore, the opening and closing of the cover can be automated, and the operation is simple and reliable. In this structure, a mechanical structure is used to control the opening and closing of the cover, without electronic devices. Therefore, it is not affected by high temperature. After the components are heated, their opening and closing functions are not affected.

[0085] Structure 2: As Figure 13As shown in the figure, the locking device is a quick clamp 5531. The clamp body of the quick clamp is fixed on the upper cover pressing frame, and the clamp hook 5532 is fixed on the lower box pressing frame. After closing the cover, hang the hanging ring of the quick clamp on the clamp hook, and press down the quick clamp handle to closely fit the upper cover and the lower box together. The structure of the quick clamp is a prior art and can be purchased on the market, so it will not be elaborated here.

[0086] Structure Three: As Figure 14 shown in the figure, the locking device includes a screw rod 5534, a screw rod support 5533, and a rotating handle 5535. The screw rod support 5533 is fixed on the lower box pressing frame. The screw rod is rotatably connected to the screw rod support through a screw rod rotating shaft 5537. Two pressing blocks 5536 are fixed on the upper cover pressing frame, and the distance between the two pressing blocks is slightly larger than the diameter of the screw rod. The rotating handle is threadedly connected to the screw rod, and the position of the screw rod is correspondingly set with the positions of the two pressing blocks. When locking is required, loosen the rotating handle, insert the screw rod between the two pressing blocks, and then rotate the rotating handle to closely fit the rotating handle and the pressing blocks, so as to closely fit the upper cover and the lower box together.

[0087] As Figure 7 shown in the figure, in the present utility model, the vacuum structure includes a vacuum conduit 541, a vacuum collection pipe 543, and a vacuum docking structure. The vacuum conduit 541 is fixedly arranged inside the upper pressing frame of the lower box. Vacuum extraction holes 542 are distributed on the vacuum conduit, and the vacuum extraction holes face the inside of the upper pressing frame of the lower box. A plurality of vacuum communication holes 545 communicating with the vacuum conduit are distributed on the upper pressing frame of the lower box. A vacuum collection pipe 543 is fixedly arranged outside the upper pressing frame of the lower box, and the vacuum collection pipe communicates with each vacuum communication hole. A vacuum tube joint 544 communicates with the vacuum collection pipe. Connect to the vacuum device through the vacuum tube joint. In order to achieve automatic docking with the vacuum device, a soft pressure box vacuum pipeline docking device is also provided, and this soft pressure box vacuum pipeline docking device is used to dock with the vacuum pipeline docking device provided on the vacuum device. The specific structure of the soft pressure box vacuum pipeline docking device is shown later. With this vacuum structure, since a plurality of vacuum communication holes communicating with the vacuum conduit are distributed on the upper pressing frame of the lower box, a vacuum collection pipe 543 is fixedly arranged outside the upper pressing frame of the lower box, the vacuum collection pipe communicates with each vacuum communication hole, and the vacuum tube joint 544 communicates with the vacuum collection pipe, therefore, when extracting vacuum, the periphery inside the soft pressure box is all connected to the vacuum extraction pipeline, and the uniformity of the vacuum degree distribution inside the soft pressure box is good, which is beneficial to uniformly pressing the components.

[0088] As Figure 8 and Figure 10As shown, due to the elasticity of the silicone plate, due to gravity, the upper silicone plate 5101 and the lower silicone plate 5201 will form a drooping concave surface after installation. The curvature of the concave surface is adjusted to make this curvature close to the curvature of the pressed component. The upper and lower silicone plates are adjusted to this curvature, and the component is placed between the two silicone plates. After closing the cover, the two silicone plates almost overlap with the component. When vacuuming, the excess gas in the soft pressure box is extracted. Since the silicone plate has a certain elasticity, the part of the component that does not overlap with the silicone plate is stretched by the elasticity of the silicone plate to supplement this part, thereby evacuating the space between the two silicone plates into a vacuum state, and the component is pressed into a whole by the external atmospheric pressure. The upper silicone plate and the lower silicone plate are pre-adjusted to be consistent with the curvature of the pressed component, so that the two silicone plates almost overlap with the component. In this way, when vacuuming, the tension on various parts of the upper silicone plate and the lower silicone plate is consistent, and the pressure on the component is consistent. While preventing local deformation of the upper silicone plate and the lower silicone plate, it can also prevent pressure deformation of the silicone plate caused by the curvature of the component, so that the pressure of various parts of the silicone plate on the component is consistent.

[0089] It is best to set up a soft pressure box moving device, and transfer the soft pressure box through the soft pressure box moving device, so that the soft pressure box can automatically enter the main body of the laminating machine, and at the same time achieve the purpose of transferring the laminated components. The soft pressure box moving device includes a track wheel 5012 and a moving thrust rod 5011. A plurality of track wheels 5012 are fixed on the lower box base 501. The track wheels are arranged on both sides of the soft pressure box. The moving thrust rod 5011 is fixed below the lower box base 501 and is located between the track wheels on both sides. The moving thrust rod is used to receive external force during automatic operation. During automatic operation, the moving thrust rod is pushed forward by external force so that the track wheel carries the soft pressure box forward, thereby driving the entire soft pressure box to move. Preferably, a rigid moving thrust rod is used.

[0090] The soft pressure box is provided with a soft pressure box moving device, and the soft pressure box moves along the track under the drive of the soft pressure box moving device, so it is convenient to fully implement the entire lamination process. The soft pressure box using the structure of the utility model can run along the track when an external force pushes the moving thrust rod. The track can support the soft pressure box and guide the forward direction of the soft pressure box, which has the following advantages: Under normal circumstances, in order to achieve good sealing and not deform under pressure at high temperature, 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 kilograms, so that the force on the conveying device is relatively concentrated. The soft pressure box using the structure of the utility model can run along the track under the push of an external force, and the track supports the soft pressure box by gravity. The external force only needs to overcome the friction between the track and the track wheel. Therefore, a relatively small force can be applied to achieve the transmission of the laminated assembly, and the weight of the soft pressure box body will not cause deformation of the conveying device.

[0091] The laminator main machine 300 of the present utility model is used to evacuate the soft pressing box and heat up the components in the soft pressing box to complete the lamination and curing of the rigid curved surface components. As Figures 23 - 27 shown, the laminator main machine includes a main machine frame 350, a heating box 310, a main machine driving device, a main machine track 314, a main machine vacuum system 320, a heating device 330, a soft pressing box clamping and positioning device 340, and a soft pressing box main machine position detection device.

[0092] The heating box 310 includes a sealed box body 311, a door panel 312, and a door panel opening and closing device 313. A soft pressing box inlet and a soft pressing box outlet are respectively arranged on the front and rear sides of the box body. Door panels are respectively arranged at the soft pressing box inlet and the soft pressing box outlet. One end of the door panel is hinged to the box body through a hinge 3134, and a door panel pin shaft 3131 is arranged at the end of the door panel opposite to the hinge. The door panel is driven to open and close through the door panel opening and closing device. The door panel opening and closing device includes a door panel cylinder 3133 and a door panel ball eye joint 3132. The output end of the door panel cylinder is connected to one end of the door panel ball eye joint, and the other end of the door panel ball eye joint is rotatably connected to the door panel pin shaft 3131. The door panel cylinder 3133 is hinged to the door panel cylinder fixing seat 3135 through a door panel cylinder pin shaft 3136, and the door panel cylinder fixing seat is fixedly connected to the main machine frame. When the soft pressing box is about to enter, the door panel cylinder at the soft pressing box inlet acts, and the inlet door panel opens. After entering, the door panel cylinder at the soft pressing box inlet acts, and the inlet door panel of the soft pressing box closes. When the soft pressing box is about to be removed, the door panel cylinder at the soft pressing box outlet acts, and the outlet door panel of the soft pressing box opens. After the soft pressing box is completely removed, the outlet door panel of the soft pressing box closes. The setting of the heating box can conduct closed heating on the soft pressing box, make full use of heat, improve the heating efficiency, reduce the heating time, and save energy.

[0093] The main machine track 314 is located inside the heating box and is fixedly arranged on the main machine frame. Usually, two main machine tracks 314 are arranged in parallel, extending from the inlet of the soft pressing box to the outlet of the soft pressing box. The upper surface of the main machine track is higher than the bottom of the inlet and the outlet of the soft pressing box, and is used to receive the soft pressing box 500, and is in rolling fit connection with the track wheels 5012 fixedly arranged on the lower box base 501 of the soft pressing box 500. The soft pressing box moves on the main machine track under the drive of the main machine drive device. The main machine drive device 315 preferably adopts the following structure, including a main machine chain drive device and a main machine linkage rod 3151. The main machine chain drive device includes a main machine driving shaft 3152 and a main machine driven shaft 3153. At both ends of the main machine driving shaft, main machine driving sprockets 3154 are respectively arranged. At both ends of the main machine driven shaft, main machine driven sprockets 3155 are respectively arranged. The main machine driving shaft and the main machine driven shaft are respectively rotatably arranged on the main machine frame. The main machine driving shaft is connected to the main machine transmission motor 3156. The length directions of the main machine driving shaft and the main machine driven shaft are perpendicular to the length direction of the main machine track and are respectively located at both ends of the main machine track, and the corresponding main machine driving sprockets and main machine driven sprockets are connected by a main machine chain 3157. Specifically, the main machine transmission motor 3156 is fixed on the main machine frame 350. The two main machine driving sprockets 3154 are respectively fixed at both ends of the main machine driving shaft 3152, and the main machine driving shaft 3152 is connected to the main machine transmission motor 3156. The two main machine driven sprockets 3155 are respectively fixed at both ends of the main machine driven shaft 3153, and the main machine driven shaft 3153 is rotatably connected to the main machine frame 350. The two main machine chains 3157 are respectively installed on the sprockets of the main machine driving shaft and the main machine driven shaft. A plurality of main machine linkage rods 3151 are fixedly arranged in parallel, and both ends of which are respectively fixedly connected to the main machine chain 3157 at the corresponding end. The main machine transmission motor 3156 rotates to drive the sprockets to rotate, thereby driving the transmission of the main machine chain 3157, and then driving the main machine linkage rod 3151 installed on the chain to move. The main machine linkage rod 3151 is in contact connection with the moving thrust rod arranged on the soft pressing box, and the soft pressing box 500 is pushed to move along the main machine track from the inlet side of the soft pressing box to the outlet side of the soft pressing box by pushing the moving thrust rod.

[0094] The main machine drive device adopting the structure of the present utility model to drive the soft pressing box to move has the following advantages: In the present utility model, the main machine track is in rolling connection with the rollers arranged at the bottom of the soft pressing box, the main machine linkage rod is driven to move by the chain drive device, and the soft pressing box is pushed forward by the main machine linkage rod. A relatively large soft pressing box can be pushed with a relatively small force. The chain drive device provides the power for the soft pressing machine to move forward, and the main machine track supports and guides the moving direction of the soft pressing machine. Therefore, the soft pressing box runs smoothly, and can smoothly push the relatively heavy soft pressing box composed of metal components to the required position, and can realize the positioning and transmission of the laminated components.

[0095] The mainframe vacuum system 320 is used to connect with the vacuum structure of the soft nip calender so as to connect the vacuum pump with the inner cavity of the soft nip calender, evacuate the inner cavity of the soft nip calender and break the vacuum in the soft nip calender and the pipeline. It includes a vacuum pipeline docking device, a vacuum pumping control device and a vacuum breaking device. The soft nip calender is docked with the vacuum device through the vacuum pipeline docking device, the soft nip calender is evacuated through the vacuum pumping control device and the vacuum pump, and the vacuum in the soft nip calender and the vacuum pipeline is broken through the vacuum breaking device. The vacuum pipeline docking device includes a soft nip calender side vacuum docking flange 3211, a mainframe side vacuum docking flange 3221 and a vacuum docking driving device. Generally, the vacuum docking driving device uses a cylinder or an electric cylinder. An O-ring seal groove A is provided on the side of the mainframe side vacuum docking flange opposite to the soft nip calender side vacuum docking flange. An O-ring seal A is fixed in the O-ring seal groove A, and the other side thereof is fixed to the vacuum docking frame body 3225. The vacuum docking frame body 3225 is connected to the vacuum docking driving device, and the vacuum docking driving device is fixed on the vacuum docking base two 3226. The vacuum docking frame body 3225 is slidably connected to the linear slide rail one 3227, and the linear slide rail one 3227 is connected to the vacuum docking base one 3228. The mainframe side vacuum docking flange is used to dock and connect with the soft nip calender side vacuum docking flange of the soft nip calender. One end of the vacuum hose 32210 is hermetically connected to the vacuum through hole provided on the mainframe side vacuum docking flange 3221, and the other end is hermetically connected to the vacuum pipe 3229. The other end of the vacuum pipe 3229 is connected to the vacuum valve 32211, and the other end of the vacuum valve 32211 is connected to the vacuum manifold 32213 through the vacuum branch pipe 32212. Multiple vacuum branch pipes 32212 can be installed on the vacuum manifold 32213 according to needs for connecting different soft nip calenders. One end of the vacuum pump connecting pipe 32214 is connected to the vacuum manifold 32213, and the other end is used to connect to the vacuum pump 32215. The vacuum pumping control device 323 preferably adopts the following structure, including a pneumatic pilot vacuum valve 32318, a pilot gas docking flange A 32317, a pilot gas docking flange B 3232 and a pilot gas docking driving device for driving the docking of the pilot gas docking flanges A and B. The air intake port and the air outlet port of the pneumatic pilot vacuum valve 32318 are respectively connected to the cavity connecting pipe 3214 and the soft nip calender side vacuum docking flange, and the pilot gas intake port is connected to the pilot gas docking flange A 32317. The pneumatic pilot vacuum valve 32318 is connected to the pilot gas docking flange A 32317 through the pilot gas pipe 32319. Generally, a cylinder or an electric cylinder B is used as the pilot gas docking driving device 3235. An O-ring seal groove B 3231 is provided on the side of the pilot gas docking flange B 3232 opposite to the pilot gas docking flange A. An O-ring seal B 3233 is fixed in the O-ring seal groove B, and the other side is fixedly connected to the pilot docking frame body. The pilot docking frame body 3234 is connected to the cylinder or the electric cylinder B serving as the pilot gas docking driving device, and the cylinder or the electric cylinder B 3235 is fixed on the pilot docking base two 32316.The leading docking frame 3234 is slidably connected to the linear slide rail two 32314 fixed on the leading docking base one 32315. The length direction of the linear slide rail two 32314 is perpendicular to the end face of the leading docking flange A. When the pneumatic pilot vacuum valve 32318 needs to be opened, the leading air docking drive device pushes the leading docking frame 32314 towards the leading air docking flange A, thereby pushing the leading air docking flange B closer to the leading air docking flange A for docking. The leading air docking flange A 32317 and the leading air docking flange B 3232 are sealed by the O-ring B. The movement distance of the leading air docking flange B 3232 is compensated by the inflation hose 3236. One end of the inflation hose 3236 is connected to the leading air docking flange B 3232, and the other end is connected to the inflation pipe 3237. The other end of the inflation pipe 3237 is connected to the switch valve 32310, and the other end of the switch valve 32310 is hermetically connected to the inflation manifold 32313 through the inflation branch pipe 32311. Multiple inflation branch pipes 32311 can be installed on the inflation manifold 32313 as required, and the gas source enters from the inflation manifold interface 32312. The vacuum-breaking device preferably adopts the following structure, including a vacuum-breaking valve 3242, a bleed valve 3244, a vacuum tube connector 3241, and an inflation pipe connector 3243. One end of the inflation pipe connector 3243 is connected to the inflation pipe 3237, and the other end is connected to the bleed valve 3244. The vacuum-breaking valve is connected to the vacuum tube 3229 through the vacuum tube connector 3241. When the pneumatic pilot vacuum valve 32318 needs to be opened, after the leading air docking flange A 32317 and the leading air docking flange B 3232 are docked, the switch valve 32310 is opened, and the compressed air passes through the switch valve 32310, the leading air docking flange B 3232, and the leading air pipe 32319 and then enters the pneumatic pilot vacuum valve 32318, thereby opening the pneumatic pilot vacuum valve 32318. When the pneumatic pilot vacuum valve 32318 needs to be closed, first, the switch valve 32310 is closed to stop the air supply, then the bleed valve 3244 is opened to discharge the compressed air in the leading air pipe 32319. Since there is no positive pressure in the leading air pipe 32319, the pneumatic pilot vacuum valve 32318 is closed at this time. Then, the leading air docking drive device 3235 drives the leading air docking flange B 3232 to disengage from the leading air docking flange A 32317. By adopting the vacuum pumping control device of the present utility model, since the pneumatic pilot valve is used to control the opening and closing of the vacuum pumping device, the pneumatic pilot valve can be conducted under positive pressure and closed when the positive pressure is lost. Therefore, the conduction of the vacuum pumping pipeline and the soft pressure box is completely controlled by mechanical devices. Compared with using electronic devices such as solenoid valves to control the on-off between the soft pressure box and the vacuum pumping device, the control valve is not affected by high temperature and can achieve docking at high temperature. There is no need for a power supply on the entire soft pressure box, so no wires need to be set. The soft pressure box can be moved arbitrarily to any position without being restricted by wires. It starts when positive pressure is applied and automatically closes when there is no positive pressure vacuum. The start and stop of the vacuum are reliable.In the vacuum pumping control device of the present utility model, an air release valve 3244 is provided. When the soft pressure box needs to leave after vacuum pumping is completed, the positive pressure remaining in the air supply pipeline is broken through the air release valve 3244 in advance, which can prevent aeration from occurring when the pneumatic pilot flange A and the pneumatic pilot flange B leave while the air supply pipeline is still in a positive pressure state, and can eliminate potential safety hazards.

[0096] The main machine vacuum system 320 that uses the above-mentioned flange combined with an O-ring to achieve sealed docking can realize the dynamic docking of the soft pressure box with the vacuum device and the inflation device, realize the inflation and vacuum breaking of the on-line soft pressure box, and thus can realize the automation of air extraction from the soft pressure box, with a simple and reliable structure. It is also possible to use a conical docking structure of a cone body plus an O-ring for docking. The conical docking structure includes a tapered hole docking seat 3216 and a conical docking head 3217. The tapered hole docking seat includes a tapered hole seat body 32161 and a tapered hole docking seat vacuum joint 32162. The tapered hole docking seat vacuum joint 32162 is integrally and fixedly connected to the tapered hole seat body. The tapered hole 32163 of the tapered hole seat body is hermetically connected to one end of the tapered hole docking seat vacuum joint, and its small-diameter end is connected to the tapered hole docking seat vacuum joint. The other end of the tapered hole docking seat vacuum joint is connected to the pneumatic pilot vacuum valve 32318. The conical docking head 3217 includes a conical head 32171 and a cone head connecting flange 32172. A through hole 32173 is provided in the cone 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 tapered hole, and the two are connected by insertion. The conical head is connected to the vacuum docking driving device. By using the above two plug-in docking structures, automatic docking can be achieved. Or directly use threads for sealed connection. The soft pressure box side vacuum docking flange and the soft pressure box side tapered hole docking seat 3216 serve as the soft pressure box side vacuum docking structure, and the main machine side vacuum docking flange and the main machine side conical docking head 3217 serve as the main machine side vacuum docking structure. The pilot air docking flange A and the pilot air tapered hole docking seat 3216 are called the pilot air needle vacuum docking structure A, and the pilot air docking flange B and the pilot air conical docking head 3217 are called the pilot air docking structure B.

[0097] When vacuum docking is required, the cylinder or electric cylinder A, which is the vacuum docking driving device, pushes the vacuum docking frame body towards the soft pressure box side vacuum docking flange, thereby pushing the main machine side vacuum docking flange close to the soft pressure box side vacuum docking flange for docking, and relying on the O-ring A to seal the main machine side vacuum docking flange and the soft pressure box side vacuum docking flange. The vacuum hose compensates for the movement distance of the soft pressure box side vacuum docking flange.

[0098] After the vacuum docking flange on the host side is docked with the vacuum docking flange on the flexible pressing box side and the pneumatic pilot vacuum valve 32318 is opened, the vacuum valve 32211 is opened, and the vacuum pump 32215 starts to evacuate the inner cavity of the flexible pressing box 500. After the evacuation is completed, first close the pneumatic pilot vacuum valve 32318 to ensure the vacuum degree inside the flexible pressing box cavity, then close the vacuum valve 32211, and then open the vacuum-breaking valve 3242 to break the vacuum in the pipeline. After that, the vacuum docking drive device pulls the vacuum docking flange 3221 on the host side back to its original position, and the flexible pressing box 500 can be moved away for the next process. Usually, the vacuum docking flange on the flexible pressing box side, the pneumatic pilot valve, and the pneumatic pilot docking flange A are all connected to the flexible pressing box through the pipeline 3214. When the flexible pressing box moves, it drives the vacuum docking flange on the flexible pressing box side, the pneumatic pilot valve, and the pneumatic pilot docking flange A to move.

[0099] When the flexible pressing box 500 needs to break the vacuum state, after the vacuum docking drive device 3224 pushes the vacuum docking flange on the flexible pressing box side and the vacuum docking flange on the vacuum side to complete the docking, the inflation device is used for inflation. The pneumatic pilot vacuum valve 32318 is opened, and then the vacuum-breaking valve is opened. Air enters the pneumatic pilot vacuum valve through the vacuum-breaking valve and finally enters the flexible pressing box 500 to break the vacuum inside the flexible pressing box. When using this device to break the vacuum inside the flexible pressing box, the outside air enters the flexible pressing box from the vacuum-breaking valve, without the need for an additional inflation device, with a simple structure and low cost.

[0100] Such as Figures 23 - 27As shown, the heating device 330 includes a heating element 331 and an air disturbance device 332. The heating element can be an electric heating rod, a heating pipeline, a heating plate, etc. The heating element is fixed on the mainframe rack 350 of the laminator and is distributed in the heating chamber 310. The number of heating elements 331 can be determined according to the size of the curved surface soft pressing box 500 and the power of the heating element 331 itself, and is used to provide the heat source required by the laminator. The air disturbance device disturbs the air in the heating chamber of the heating box to make it flow in the heating box. Usually, the air disturbance device uses a fan 3321, and the fan motor 3322 is fixed on the mainframe rack 350 of the laminator, and the air outlet of the fan faces the inside of the heating chamber of the heating box. A plurality of fans are provided, and the air outlets of each fan are all arranged on the side walls on both sides and / or the side walls at the ends of the box body of the heating box. The mainframe vacuum system can be entirely located inside the heating box or partially located inside the heating box. A pipeline interface is provided on the heating box for the vacuum pipeline to pass through. When it is partially located inside the heating box, at least the vacuum pipeline docking device is arranged inside the heating box, and preferably the vacuum pumping control device is also arranged inside the heating box to ensure good docking sealing of the entire device. In this way, the mainframe vacuum system can be smoothly docked with the soft pressing box. In order to reduce the overall volume of the heating box and save heating energy, a mainframe vacuum system protection box 370 connected to the heating box is arranged at the position where the side of the heating box is docked with the soft pressing box, and the mainframe vacuum system is arranged inside the mainframe vacuum system protection box. The pipeline interface for the vacuum pipeline to enter and exit is arranged on the mainframe vacuum system protection box.

[0101] The setting of the mainframe track and the mainframe driving device can drive the soft pressing box, thereby completing the automatic transmission and transfer of the laminated components.

[0102] Figures 23 - 27 In the illustrated embodiment, a plurality of laminating mainframes are provided. The laminating mainframes are stacked up and down, and 4 fans 3321 are installed on each layer to disturb the air in the heating chamber of the heating box. The air flows in the heating chamber of the heating box, thereby driving the heat of the heating element 331 to be more evenly distributed in the entire chamber. The number of fans 3321 is based on the principle of better driving the heat of the heating element 332 to be more evenly distributed. This figure shows that 8 heating elements 331 are installed on each layer.

[0103] Preferably, a soft pressing box clamping and positioning device 340 and a soft pressing box mainframe position detection device are provided to make the soft pressing box stop correctly at a fixed position after entering the heating box, which is convenient for docking with the mainframe vacuum control system.

[0104] The soft pressing box clamping and positioning device includes a limit plate 341, a limit shaft 342, a force transmission rod 343, and a limit plate rotation driving device 344. One end of the limit shaft 342 is fixed to the limit plate 341, and the other end is fixed to the force transmission rod 343. One end of the clamping ball eye joint 345 is rotatably connected to the other end of the force transmission rod 343 through a clamping pin shaft 346. Usually, a clamping cylinder is used as the limit plate rotation driving device 344. One end of the limit plate rotation driving device 344 is connected to the other end of the clamping ball eye joint 345. The clamping cylinder seat and the clamping cylinder fixing seat 347 are rotatably connected through a clamping cylinder pin shaft 348. When the cylinder rod of the clamping cylinder extends or retracts, it drives the limit shaft 342 to rotate, thereby driving the limit plate 341 to rotate. When the soft pressing box clamping device is in the waiting state, the limit plate is in the horizontal position. Two soft pressing box clamping and positioning devices are respectively arranged inside the two main machine tracks 314. The limit plates of the four soft pressing box clamping and positioning devices are at the same height. The spacing between the tracks is adapted to the length of the soft pressing box body, that is, one limit plate 341 is symmetrically arranged on each side of the inlet end and the outlet end of the main machine of the laminator, that is, 4 limit plates are configured. Before the curved surface soft pressing box 500 enters the main machine of the laminator for soft pressing, the limit plates 341 at the inlet end and the outlet end are both in the horizontal state. When the curved surface soft pressing box 500 enters the main machine of the laminator and reaches the predetermined position, the soft pressing box is between the four limit plates, and each limit plate rotation driving device acts, so that the limit plates 341 at the inlet end and the outlet end both rotate towards the curved surface soft pressing box 500, thereby clamping the curved surface soft pressing box 500 between the four limit plates for position fixing. When multiple layers of main machines of the laminator are set, one soft pressing box clamping and positioning device is arranged on each side of the inlet end and the outlet end of each heating box, and the limit plates on both sides of the heating box are symmetrically arranged, that is, 4 limit plates for each layer. In order to make the soft pressing box accurately stop at the set position, a soft pressing box position detection device is provided. When the soft pressing box enters the position between the four limit plates, the soft pressing box position detection device emits a signal, and the main machine driving device 315 stops driving, and the limit plate rotation driving device drives the limit plate to act to clamp and fix the soft pressing box.

[0105] The working process of the main body of the laminator is as follows: When the soft pressing box 500 is about to enter the main body of the laminator for soft pressing, the door panel at the inlet end is opened under the drive of the door panel opening and closing device, the main body transmission motor 3156 starts, drives the main body chain 3157 to run, drives the main body linkage rod 3151 to push the soft pressing box 500 forward. After the soft pressing box 500 completely enters the main body of the laminator for soft pressing, the door panel is closed under the drive of the door panel opening and closing device. After the soft pressing box 500 moves to the docking position of the main body vacuum system 320, under the drive of the clamping cylinder, the four limit plates 421 rotate towards the soft pressing box 500, clamp the soft pressing box between the four limit plates, and fix the soft pressing box 500. At this time, the vacuum docking drive device of the main body vacuum system 320 starts, drives the main body side vacuum docking flange to dock with the soft pressing box side vacuum docking flange, the pilot gas docking flange drive device drives the pilot gas docking flange B to move towards the pilot gas docking flange A for docking, the inflation device inflates, makes the pneumatic pilot vacuum valve conduct, the vacuum device is turned on, evacuates the soft pressing box 500, and the hot air in the heating box heats the whole soft pressing box, and the components start laminating. After the evacuation is completed and the laminating and curing are completed, the vacuum breaking device of the main body vacuum system 320 breaks the vacuum of the soft pressing box 500. After all the actions of the main body vacuum system 320 are completed, the main body vacuum system 320 is disengaged from the soft pressing box 500, the four limit plates 421 rotate in the reverse direction, release the fixation of the soft pressing box 500, the main body transmission motor starts again, drives the main body linkage rod 3151 to push the soft pressing box 500 forward. Before the soft pressing box 500 exits the main body of the laminator, the door panel at the outlet end is opened. After the soft pressing box 500 completely exits, the door panel is closed.

[0106] When heating is required, the heating element starts to heat, and the fan starts to rotate to evenly distribute the heat in the cavity.

[0107] The laminator of the present utility model can directly place the soft pressing box filled with materials on the main body of the laminator, or can complete the material loading on the loading table, and then transmit the soft pressing box to the main body of the laminator through the loading table, and / or can directly remove the soft pressing box after laminating from the main body of the laminator, or can receive the soft pressing box transmitted from the main body of the laminator through the unloading table, and complete the unpacking and unloading on the unloading table.

[0108] Such as Figures 15 - 18As shown in the figure, the loading table preferably adopts the following structure: it includes a loading frame body 110, a loading transmission device 130, a switch cover device 140, and a switch lock device 150. The switch cover device is used to open and close the soft pressing box, and the switch lock device is used to unlock and lock the soft pressing box. The loading transmission device transmits the soft pressing box that has completed loading, closing the cover, and locking the cover to the main body of the laminator. Specifically as follows: after the loading transmission device receives the soft pressing box, the switch lock device 150 opens the locking device, the switch cover device 140 automatically opens the soft pressing box. After the curved surface material is placed in the soft pressing box, the switch cover device 140 can automatically close the soft pressing box. The switch lock device 150 drives the locking device to tighten the cover of the soft pressing box, and then transmits the soft pressing box to the inside of the box body of the laminator main body through the loading transmission device 130.

[0109] The loading transmission device 130 preferably adopts the following structure, including two parallel loading tracks 1307, a loading chain transmission device, and a loading linkage rod 1301. The loading chain transmission device includes a loading drive motor 1306, a loading main transmission shaft 1304, and a loading driven shaft 1305. The loading main transmission shaft and the loading driven shaft are arranged in parallel and rotatably in the loading transmission direction of the loading frame body 110. At both ends of each loading driven shaft, loading sprockets 1302 are fixedly arranged respectively. At both ends of each loading main transmission shaft, loading sprockets 1302 are fixedly arranged respectively. The loading main transmission shaft is connected to the loading drive motor; the loading chain 1303 is wound around the loading sprockets of the loading main transmission shaft and the loading driven shaft. Both ends of the loading linkage rod 1301 are fixedly connected to the corresponding side of the loading chain. One or more loading linkage rods can be installed according to needs. The loading track is arranged parallel to the loading chain. The loading track and the main machine track are set at the same height. The discharging end of the loading track and the feeding end of the main machine track are arranged opposite to each other. The soft pressing box can be moved from the loading track into the main machine track under the drive of the loading transmission device.

[0110] The switch cover device 140 preferably adopts the following structure, including a switch cover bracket 141 and a switch cover drive 142. The lower end of the switch cover bracket is fixedly connected to the loading base 1101, and the upper end of the switch cover bracket is higher than the soft pressing box 500 located on the loading frame body 110. The switch cover drive 142 is a linear reciprocating drive device. Its main body is rotatably connected to the upper end of the switch cover bracket through a pin shaft. A switch cover joint 143 is arranged at the output end of the switch cover drive 142. When the soft pressing box is placed on the loading track 1307, the fork-shaped opening of the switch cover joint corresponds to the position of the thrust shaft of the lifting arm of the soft pressing box. When the switch cover drive drives the switch cover joint to move downward, it can encounter the thrust shaft and push the thrust shaft downward, so that the lifting arm can be lifted under the action of the switch cover drive, opening the upper cover of the soft pressing box. When the switch cover drive returns, the switch cover joint leaves the thrust shaft, closing the upper cover of the soft pressing box.

The output end of the switch lock driving device is fixedly connected with a switch lock joint 152. The switch lock driving device is a linear reciprocating driving device. When the soft pressing box enters the loading table, the position of the switch lock joint corresponds to the position of the pressing head provided on the tension rod of the soft pressing box. When the switch lock driving device drives the switch lock joint to move downward, it can push the pressing head to make the tension rod leave the upper cover.

The track wheels 5012 fixedly provided on the lower box base 501 of the soft pressing box are in rolling cooperation with the loading track, and the loading linkage rod is in contact connection with the moving thrust rod. During automatic operation, the moving thrust rod is pushed by the loading linkage rod to drive the entire soft pressing box to move.

[0112] The operation process of the loading table is as follows: When the loading table receives the soft pressing box, that is, after the soft pressing box is placed on the loading track 1307, before the switch cover driving starts to work, the switch lock driving device starts to drive the switch lock joint to move towards the tension rod of the soft pressing box locking device. The switch lock joint pushes the end of the locking device's tension rod opposite to the pressing head, opens the locking device. At this time, the switch cover driving drives the switch cover joint to move towards the soft pressing box thrust shaft 531, presses down the thrust shaft to open the soft pressing box. After the material is loaded, the switch cover driving drives the switch cover joint to retract, closes the soft pressing box, and the switch lock driving device drives the switch lock joint to retract to close the soft pressing box locking device. After the locking device is closed, the loading transmission motor rotates to drive the loading sprocket to rotate, thereby driving the loading linkage rod to move. The loading linkage rod contacts the moving thrust rod of the soft pressing box and pushes the soft pressing box to move, removing the soft pressing box from the loading table and entering the next process, that is, entering the main machine track of the laminator main machine.

After the lamination and curing is completed, the main drive device drives the soft pressure box to the discharge track of the discharge table, and the soft pressure box discharge lifting device drives the soft pressure box to lift and dock with the discharge chain of the discharge driving device and drives it into the discharge track. The soft pressure box unloading lifting device drives the soft pressure box to lift and dock with the discharge track. After unlocking and opening the cover at the unloading table, the components are moved out of the soft pressure box. After the cover is closed and locked, the soft pressure box is driven by the soft pressure box unloading lifting device to dock with the return track. The soft pressure box unloading driving device runs in reverse to push the soft pressure box into the return track. The return driving device drives the soft pressure box back to the feeding table side, and the loading table is lifted and lowered to dock its loading track with the return track, and the soft pressure box is transported back to the loading table for loading to complete a cycle.

[0128] When the laminator main machine is provided with two chambers, the working process is as follows: After the soft pressing box is preheated and evacuated in one chamber of the laminator main machine, it enters the second chamber of the press main machine to complete the lamination and curing of the component. After the component lamination is completed, the second chamber of the laminator main machine pushes out the soft pressing box. After the discharging lifting device of the discharging table receives the soft pressing box and descends to the feeding height of the first layer, the discharging driving device 230 then pushes the soft pressing box into the discharging table. After the discharging table receives the soft pressing box and descends it to the height of the return layer, the soft pressing box is opened. After the component is taken out, the soft pressing box is closed, and the soft pressing box is pushed into the return layer. The return layer conveys the soft pressing box back to the loading table to complete a single cycle.

[0129] The docking referred to in the present utility model means that the input and output ends of two chains are opposite, and the entering and exiting ends of two tracks are opposite, so that the soft pressing box can be transferred from one chain to another chain, or from one track to another track.

[0130] In the present utility model, the soft pressing box transmission device of each unit adopts a structure of a track and a chain transmission device plus a linkage rod. The chain transmission device drives the linkage rod to operate, and the linkage rod pushes the soft pressing box to move forward on the track. The advantages of adopting this structure are as follows: First, the track can support the soft pressing box and guide the forward direction of the soft pressing box, and the chain transmission device provides power for the forward movement of the soft pressing box. The combination of the two can push the heavy soft pressing box to move forward smoothly. Moreover, each section of the chain is rigid, so it will not elongate and deform due to resistance. Therefore, after the linkage rod is set, it will not generate position changes due to the deformation of the two side chains, and the force application direction has good consistency; Second, each unit is independently provided with a chain transmission device to drive the soft pressing box, and the soft pressing box can be moved at any time according to needs without being restricted by other units. The setting of the pure mechanical structure can be well conveyed in the high-temperature box without generating high-temperature deformation; Third, usually, in order to achieve good sealing and no deformation under pressure at high temperature, the box body of the soft pressing box is made of metal components, and its weight is relatively large. A soft pressing box can reach several hundred catties, making the force on the transmission device relatively concentrated. For the soft pressing box transmission device adopting the structure of the present utility model, the track supports the gravity of the soft pressing box, and 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.

[0131] For the laminator of the present utility model, a switch cover device and a switch lock device are provided on both the loading table and the discharging table, which can open and lock the soft pressing box, and a return transmission device is provided. Therefore, in the overall process, only the laminated component needs to be loaded into the soft pressing box, laminated and then taken out of the soft pressing box, and then the automatic encapsulation of the component on the entire device can be realized without manual intervention, and the automation level is high.

[0132] For the laminator adopting the structure of the present utility model, the soft pressing box serves as a vacuum chamber and a pressing device, and also serves as a transmission device for components, bringing the components to different process stations to complete the entire lamination process of the components, solving the technical problem that the conveyor belt of the existing laminator cannot stably convey curved rigid components.
