Description

Technical Field

[0001] The utility model relates to the technical field of in-vehicle central control screen assembly, and particularly relates to an in-vehicle central control screen laminating production line. Background Art

[0002] The in-vehicle central control screen is composed of components such as a glass component (TFT screen) and a middle frame component. To ensure the high quality and reliability of the in-vehicle central control screen, these components need to go through precise laminating and assembly processes. In the laminating production process, precision and efficiency are crucial. In particular, it is necessary to ensure the accuracy of the positioning of the glass component (TFT screen) and the middle frame component. Traditional in-vehicle central control screen production often relies on manual operation, which not only has low efficiency but also is prone to quality problems. Content of the Utility Model

[0003] The purpose of the utility model is to provide an in-vehicle central control screen laminating production line that can ensure the continuity and efficiency in the production process and has high laminating accuracy.

[0004] An in-vehicle central control screen laminating production line includes a front-section tray circulation machine, a first tray elevator, a first dispensing machine, a second dispensing machine, a second tray elevator, a laminating machine, and a rear-section tray circulation machine that are connected in sequence. Two groups of horizontal transfer line bodies are respectively arranged on the front-section tray circulation machine, the laminating machine, and the rear-section tray circulation machine. One group of lifting transfer line body and one group of horizontal transfer line body are respectively arranged on the first tray elevator, the first dispensing machine, the second dispensing machine, and the second tray elevator. Multiple groups of horizontal transfer line bodies and lifting transfer line bodies are combined to form a return line body, and the return line body is used for circulating and transferring line trays. The line tray includes a bottom plate and a middle frame component receiving platform and a glass component receiving platform installed on the bottom plate. The middle frame component receiving platform and the glass component receiving platform respectively carry the middle frame component and the glass component. The middle frame component receiving platform includes at least four support columns, and the middle frame component is placed on the support columns. A plurality of positioning column components are arranged around the middle frame component. The glass component receiving platform includes a pressure-holding support, a pressure-holding fixture pressing plate, and a pressure-holding fixture positioning plate. The pressure-holding fixture pressing plate overlaps on the pressure-holding support, and the pressure-holding fixture positioning plate is installed on the pressure-holding fixture pressing plate. A plurality of ridges are arranged along the side of the pressure-holding fixture positioning plate.

[0005] In the above solution, the line body tray at the starting position of the front-section tray recycling machine is loaded with a glass component and a middle frame component. The line body tray is transferred to the position of the first tray elevator through the horizontal transfer line body, and then the line body tray is transferred to the first dispensing machine or the second dispensing machine through the lifting and transfer line body on the first tray elevator to perform dispensing on the glass component. After that, it is transferred to the second tray elevator through the lifting and transfer line body on the first dispensing machine or the second dispensing machine, and then the line body tray is transferred to the laminating machine through the lifting and transfer line body on the second tray elevator. The lifting and transfer line body enables the line body tray to be transferred from the lower layer of the first dispensing machine to the second dispensing machine when the first dispensing machine is working, so as to ensure that the first dispensing machine and the second dispensing machine can operate simultaneously. After the glass component and the middle frame component are automatically laminated on the laminating machine, they are transferred to the rear-section tray recycling machine to take out the laminated products, and the line body tray can circulate on the return line body.

[0006] The bottom plate is in contact with the lifting and transfer line body or the horizontal transfer line body, so that the lifting and transfer line body and the horizontal transfer line body can drive the line body tray to move. The middle frame component is placed on the middle frame component receiving table, and the glass component is placed on the glass component receiving table. Since the glass component receiving table is higher than the middle frame component receiving table, when transferred to the laminating machine, the glass component can be lifted above the middle frame component and then flipped and laminated onto the middle frame component. The middle frame component is placed on the support columns, and a plurality of positioning column components are arranged around the outer periphery of the middle frame component to ensure the stability of the middle frame component. The pressing fixture pressing plate overlaps on the pressing support seat, and a plurality of pins are arranged on the pressing support seat. The pins can position the pressing fixture pressing plate. The pressing fixture positioning plate is installed on the pressing fixture pressing plate, and a plurality of convex strips are arranged along the side of the pressing fixture positioning plate. The convex strips can ensure the accuracy and stability of the positioning of the glass component.

[0007] Further, the front-section tray recycling machine includes a front-section lower frame component, two sets of lifting line bodies and a transverse transfer line body. The lifting line bodies, the transverse transfer line body and the two sets of horizontal transfer line bodies are all installed on the front-section lower frame component. The transverse transfer line body is arranged between the two sets of horizontal transfer line bodies. The lifting line body is connected to the horizontal transfer line body, and the lifting line body can transfer the line body tray between the transverse transfer line body and the horizontal transfer line body.

[0008] In the above solution, the horizontal transfer line body transfers the line body tray along the horizontal direction. At the position of the front-section tray recycling machine, the lifting line bodies are installed at both sets of horizontal transfer line bodies. The lifting line body can lift the line body tray to be flush with the position of the transverse transfer line body, and the lifting line body can drive the line body tray to move back and forth, so that the line body tray moves onto the transverse transfer line body, and then the line body tray is transferred from one set of horizontal transfer line bodies to the other set of horizontal transfer line bodies through the transverse transfer line body, realizing the return of the line body tray.

[0009] Further, the first tray elevator includes an elevator lower frame assembly and an elevator slide table. The elevator slide table is connected to the lifting and transferring line body, and the elevator slide table can drive the lifting and transferring line body to lift and lower. The elevator slide table and the lifting and transferring line body are installed on one side of the elevator lower frame assembly, and the horizontal transfer line body is installed on the other side of the elevator lower frame assembly.

[0010] In the above solution, when the first dispensing machine is dispensing, after the line tray loaded with the glass assembly and the middle frame assembly is transferred to the lifting and transferring line body on the first tray elevator, the elevator slide table can drive the lifting and transferring line body to descend, and the lifting and transferring line bodies on the first dispensing machine and the second dispensing machine also descend to be flush with the lifting and transferring line body on the first tray elevator. In this way, it can be ensured that the line tray passes under the line tray being dispensed on the first dispensing machine and is transferred to the lifting and transferring line body of the second dispensing machine for dispensing, so that the first dispensing machine and the second dispensing machine can work simultaneously. The horizontal transfer line body on the other side of the elevator lower frame assembly is for the return transfer of the empty line tray.

[0011] Further, the first dispensing machine includes a dispensing machine lower frame assembly, a dispensing mechanism, a glue discharging mechanism, and a glue wiping mechanism. A dispensing installation table is provided on the dispensing machine lower frame assembly, and the dispensing mechanism, the glue discharging mechanism, and the glue wiping mechanism are installed on the dispensing installation table. The lifting and transferring line body and the horizontal transfer line body are respectively arranged on both sides of the dispensing installation table. Front positioning mechanisms and rear positioning mechanisms are respectively arranged on both sides of the lifting and transferring line body, and the rear positioning mechanism is installed on the dispensing installation table. The front positioning mechanism and the rear positioning mechanism are used to position and clamp the line tray.

[0012] In the above solution, the line tray loaded with the glass assembly and the middle frame assembly is transferred to the lifting and transferring line body of the first dispensing machine through the lifting and transferring line body on the first tray elevator. The line tray is transferred to the dispensing position through the lifting and transferring line body. The dispensing mechanism first discharges glue on the glue discharging mechanism. After ensuring that the glue discharging parameters meet the production requirements, it then dispenses glue on the glass assembly. The glue wiping mechanism is used to clean the dispensing mechanism. The front positioning mechanism and the rear positioning mechanism can, on the one hand, ensure the accurate positioning of the line tray at the dispensing position, and on the other hand, stably clamp the line tray, so that the lifting and transferring line body can descend to transfer other line trays.

[0013] Further, the dispensing mechanism includes a dispensing robot, a vision component, and a dispensing component. The vision component and the dispensing component are arranged in parallel and connected to the execution end of the dispensing robot; the glue discharging mechanism includes a mounting seat, a glue receiving cup, and a needle alignment sensor. The needle alignment sensor and the glue receiving cup are adjacently installed on the mounting seat.

[0014] In the above solution, the dispensing robot can be a six-axis robot. The vision component mainly includes a camera, and the dispensing component mainly includes a dispensing valve and a valve controller. By moving the vision component and the dispensing component with the dispensing robot, the vision component can take pictures and position the dispensing position, and the dispensing component dispenses glue according to the signal of the dispensing position transmitted by the vision component; in addition, before dispensing, it is necessary to ensure the amount of glue output, so it is necessary to discharge glue in the glue discharging mechanism, the alignment sensor aligns the dispensing valve, and then discharges glue in the glue receiving cup.

[0015] Further, a tray front positioning strip and a tray rear positioning strip are provided on the bottom plate. At least two positioning holes are provided on the tray front positioning strip, and the tray rear positioning strip is L-shaped; the front positioning mechanism includes a first support component, a first sliding component and a first driving component. The first support component is installed on the lower frame component of the dispensing machine. The first sliding component is installed on the first support component. A first positioning mounting plate is slidably installed on the first sliding component. A positioning pin is installed on the first positioning mounting plate. The first driving component can drive the first positioning mounting plate to move so that the positioning pin penetrates into the positioning hole.

[0016] Further, the rear positioning mechanism includes a second support component, a second sliding component and a second driving component. The second support component is installed on the dispensing mounting table. The second sliding component is installed on the second support component. A second positioning mounting plate is slidably installed on the second support component. An L-shaped connecting positioning strip is installed on the second positioning mounting plate. The connecting positioning strip can be cooperatively abutted against the tray rear positioning strip.

[0017] In the above solution, when the in-line tray arrives at the first dispensing machine or the second dispensing machine, the first driving component on the front positioning mechanism drives the first positioning mounting plate to move so that the positioning pin penetrates into the positioning hole on the tray front positioning strip, and the second driving component on the rear positioning mechanism drives the second positioning mounting plate to move, so that the L-shaped connecting positioning strip and the L-shaped tray rear positioning strip are cooperatively abutted, thereby realizing the positioning and clamping of the in-line tray. The first sliding component ensures the stability and accuracy of the movement of the first positioning mounting plate. The first support component is used to support the first sliding component and the first driving component. The second sliding component ensures the stability and accuracy of the movement of the second positioning mounting plate. The second support component is used to support the second sliding component and the second driving component.

[0018] Further, the laminating machine includes a laminating motion mechanism and a flipping mechanism. The laminating motion mechanism is connected to the flipping mechanism. The flipping mechanism includes a flipping drive assembly and a suction cup fixing plate. The suction cup fixing plate is connected to the flipping shaft on the flipping drive assembly. A plurality of suction cup assemblies and electromagnetic suction assemblies are installed on the suction cup fixing plate. The suction cup assemblies can pass through the glass assembly and be adsorbed to the glass assembly by the pressure maintaining fixture pressing plate and the pressure maintaining fixture positioning plate on the table. The electromagnetic suction assemblies can adsorb the pressure maintaining fixture pressing plate and the pressure maintaining fixture positioning plate.

[0019] In the above solution, when the linear tray is transferred to the laminating machine, the laminating motion mechanism drives the flipping mechanism to move below the glass assembly. The glass assembly is sucked by the suction cup assemblies, and the electromagnetic suction assemblies adsorb the pressure maintaining fixture pressing plate and the pressure maintaining fixture positioning plate and then flip so that the glass assembly is laminated with the middle frame assembly. The laminated glass assembly and middle frame assembly need to be with the pressure maintaining fixture pressing plate and the pressure maintaining fixture positioning plate.

[0020] Further, the laminating motion mechanism includes an X-axis motion module, a Y-axis motion module, and a Z-axis motion module. The X-axis motion module is connected to the Y-axis motion module. The Z-axis motion module is connected to the X-axis motion module. The Z-axis motion module is connected with a sliding bottom plate. The flipping mechanism is connected to the sliding bottom plate.

[0021] In the above solution, the X-axis motion module can drive the Z-axis motion module to move along the horizontal left-right direction. The connection between the flipping mechanism and the Z-axis motion module is realized through the sliding bottom plate. The Z-axis motion module can drive the flipping mechanism to move along the vertical direction. The Y-axis motion module can drive the X-axis motion module to move along the horizontal front-back direction, so that the position of the flipping mechanism can be adjusted from multiple directions.

[0022] Further, the laminating machine further includes a laminating lower frame assembly and a laminating lifting mechanism. The laminating lifting mechanism is installed on the laminating lower frame assembly. The laminating lifting mechanism includes a tray lifting platform and a rotary alignment platform. The tray lifting platform is used for secondary positioning of the linear tray. The rotary alignment platform is used for aligning the linear tray.

[0023] In the above solution, after the tray lifting platform secondarily positions the linear tray, it lifts the linear tray. The rotary alignment platform can automatically align the receiving platform of the middle frame assembly, thus ensuring the stability and accuracy of the lamination of the middle frame assembly and the glass assembly.

[0024] The beneficial effects of a vehicle-mounted central control screen laminating production line of the present utility model are as follows:

[0025] 1. Improve production efficiency. The line pallet at the starting position of the front pallet circulation machine is loaded with glass components and middle frame components. The line pallet is transferred to the position of the first pallet elevator by the horizontal transfer line, and then transferred to the first dispensing machine or the second dispensing machine by the lifting and transferring line on the first pallet elevator to dispense glue on the glass components, and then transferred to the second pallet elevator by the lifting and transferring line on the first dispensing machine or the second dispensing machine. The first dispensing machine and the second dispensing machine can run at the same time, and then transferred to the laminating machine by the lifting and transferring line on the second pallet elevator. The automatic circulation of the line pallet and the efficient operation of each device reduce manual intervention, making the production process smoother and more continuous.

[0026] Second, it ensures product consistency and quality. The middle frame assembly is placed on the support column, and multiple positioning column assemblies are arranged around the outer periphery of the middle frame assembly to ensure the stability of the middle frame assembly. The pressure-maintaining jig pressure plate is overlapped on the pressure-maintaining support, and the pressure-maintaining support is provided with multiple pins, which can position the pressure-maintaining jig pressure plate. The pressure-maintaining jig positioning plate is installed on the pressure-maintaining jig pressure plate. The pressure-maintaining jig positioning plate is provided with multiple convex strips along the side, which can ensure the accuracy and stability of the positioning of the glass assembly. In this way, the first dispensing machine and the second dispensing machine can dispense the product more uniformly and accurately, reducing the errors that may be caused by manual operation. The bonding machine can also bond the glass assembly and the middle frame assembly more accurately and stably. This consistency and accuracy helps to improve the quality and reliability of the final product.

[0027] 3. Shortened production cycle. The automated production line effectively shortens the overall production cycle by reducing the processing time of each step and the transmission time between equipment. The design of the return line body allows the line body pallet to be recycled in the production line, avoiding production interruptions and waiting time, thereby improving production efficiency.

[0050] The following will further describe in detail a vehicle-mounted central control screen lamination production line of the present utility model in conjunction with specific embodiments and the accompanying drawings.

[0051] As Figure 1 and Figure 2As shown, in a preferred embodiment, a production line for bonding an in-vehicle central control screen of the present utility model includes a front-section tray circulation machine 1, a first tray elevator 2, a first dispensing machine 3, a second dispensing machine 4, a second tray elevator 5, a bonding machine 6, and a rear-section tray circulation machine 7 that are connected in sequence. Two groups of horizontal transfer line bodies 8 are respectively provided on the front-section tray circulation machine 1, the bonding machine 6, and the rear-section tray circulation machine 7. One group of lifting transfer line bodies 9 and one group of horizontal transfer line bodies 8 are respectively provided on the first tray elevator 2, the first dispensing machine 3, the second dispensing machine 4, and the second tray elevator 5. The multiple groups of horizontal transfer line bodies 8 and lifting transfer line bodies 9 are combined to form a return line body, and the return line body is used to circulate and transfer the line body trays 10.

[0052] The line body tray 10 at the starting position of the front-section tray circulation machine 1 is loaded with a glass component and a middle frame component. The line body tray 10 is transferred to the position of the first tray elevator 2 through the horizontal transfer line body 8, and then the line body tray 10 is transferred to the first dispensing machine 3 or the second dispensing machine 4 through the lifting transfer line body 9 on the first tray elevator 2 to dispense glue on the glass component. After that, it is transferred to the second tray elevator 5 through the lifting transfer line body 9 on the first dispensing machine 3 or the second dispensing machine 4, and then the line body tray 10 is transferred to the bonding machine 6 through the lifting transfer line body 9 on the second tray elevator 5. The lifting transfer line body 9 enables the line body tray 10 to be transferred from the lower layer of the first dispensing machine 3 to the second dispensing machine 4 when the first dispensing machine 3 is working, so as to ensure that the first dispensing machine 3 and the second dispensing machine 4 can operate simultaneously. The automatic circulation of the line body tray 10 and the efficient operation of each device reduce manual intervention and make the production process more smooth and continuous.

[0053] After the glass component and the middle frame component are automatically bonded by the bonding machine 6, they are transferred to the rear-section tray circulation machine 7 to take out the bonded products, and the empty trays continue to move on the return line body. The high-precision control of the bonding machine 6 ensures the accurate bonding of the glass component and the middle frame component. This consistency and precision contribute to improving the quality and reliability of the final product, and the line body tray 10 can circulate on the return line body, avoiding production interruption and waiting time, thereby improving production efficiency.

[0054] As Figure 2 and Figure 3As shown, in some embodiments, the line tray 10 includes a bottom plate 101, a middle frame component receiving platform 102 and a glass component receiving platform 103 mounted on the bottom plate 101. The middle frame component receiving platform 102 and the glass component receiving platform 103 respectively carry the middle frame component and the glass component, and the height of the glass component receiving platform 103 is higher than that of the middle frame component receiving platform 102. The bottom plate 101 is in contact with the lifting and transfer line body 9 or the horizontal transfer line body 8, so that the lifting and transfer line body 9 and the horizontal transfer line body 8 can drive the line tray 10 to move. The middle frame component is placed on the middle frame component receiving platform 102, and the glass component is placed on the glass component receiving platform 103. Since the glass component receiving platform 103 is higher than the middle frame component receiving platform 102, when being transferred to the laminating machine 6, the glass component can be lifted above the middle frame component and then flipped and laminated onto the middle frame component.

[0055] Referring to Figure 3 , the middle frame component receiving platform 102 includes at least four support columns 1021, and the middle frame component is placed on the support columns 1021. A plurality of positioning column components 1022 are provided around the outer periphery of the middle frame component, so as to ensure the stability of the middle frame component. The glass component receiving platform 103 includes a pressure maintaining support 1031, a pressure maintaining fixture pressing plate 1032 and a pressure maintaining fixture positioning plate 1033. The pressure maintaining fixture pressing plate 1032 overlaps on the pressure maintaining support 1031. A plurality of pins are provided on the pressure maintaining support 1031, and the pins can position the pressure maintaining fixture pressing plate 1032. The pressure maintaining fixture positioning plate 1033 is mounted on the pressure maintaining fixture pressing plate 1032, and a plurality of ridges 11 are provided along the side of the pressure maintaining fixture positioning plate 1033, and the ridges 11 can ensure the accuracy and stability of the positioning of the glass component.

[0056] As Figure 4 and Figure 5As shown, in some embodiments, the front-section tray circulation machine 1 includes a front-section lower frame assembly 110, two sets of lifting line bodies 120, and a transverse transfer line body 130. The lifting line bodies 120, the transverse transfer line body 130, and the two sets of horizontal transfer line bodies 8 are all installed on the front-section lower frame assembly 110. The transverse transfer line body 130 is disposed between the two sets of horizontal transfer line bodies 8. The lifting line bodies 120 are connected to the horizontal transfer line bodies 8, and the lifting line bodies 120 can transfer the line body tray 10 between the transverse transfer line body 130 and the horizontal transfer line bodies 8. The horizontal transfer line bodies 8 transfer the line body tray 10 along the horizontal direction. At the position of the front-section tray circulation machine 1, the lifting line bodies 120 are installed at both sets of horizontal transfer line bodies 8. The lifting line bodies 120 can lift the line body tray 10 to be flush with the position of the transverse transfer line body 130, and the lifting line bodies 120 can drive the line body tray 10 to move back and forth, so that the line body tray 10 moves onto the transverse transfer line body 130, and then the transverse transfer line body 130 transfers the line body tray 10 from one set of horizontal transfer line bodies 8 to the other set of horizontal transfer line bodies 8, realizing the return flow of the line body tray 10. This design ensures the efficient return of the trays, optimizes the fluidity of the production line, and improves the production efficiency.

[0057] In the above embodiment, the lifting line body 120 includes a connecting plate 1201, a rotation driving member 1202, a lifting plate 1203, and a lifting driving member 1204. The connecting plate 1201 is connected to the horizontal transfer line body 8. The lifting plate 1203 is located above the connecting plate 1201 and is connected to the connecting plate 1201 through a plurality of lifting driving members 1205. The lifting driving member 1204 is installed on the connecting plate 1201. The lifting driving member 1204 can be a cylinder, which can drive the lifting plate 1203 to move up and down to realize the lifting and lowering of the line body tray 10. The rotation driving member 1202 is located below the connecting plate 1201. The rotation driving member 1202 is connected with a synchronous pulley 1207 through a rotating shaft 1206. A synchronous belt 1208 is wound around the lifting plate 1203 and the synchronous pulley 1207. In this way, the rotation driving member 1202 can drive the synchronous belt 1208 to run to drive the line body tray 10 to move. Since the structure of the rear-section tray circulation machine 7 is basically the same as that of the front-section tray circulation machine 1, the structure of the rear-section tray circulation machine 7 will not be described in detail here.

[0058] As Figure 6 and Figure 7As shown, in some embodiments, the first pallet elevator 2 includes an elevator lower frame assembly 21 and an elevator slide table 22. The elevator slide table 22 is connected to the lifting transfer line body 9. The elevator slide table 22 can drive the lifting transfer line body 9 to lift and lower. The elevator slide table 22 and the lifting transfer line body 9 are installed on one side of the elevator lower frame assembly 21, and the horizontal transfer line body 8 is installed on the other side of the elevator lower frame assembly 21. When the first dispensing machine 3 is performing dispensing, after the line body pallet 10 loaded with the glass assembly and the middle frame assembly is transferred to the lifting transfer line body 9 on the first pallet elevator 2, the elevator slide table 22 can drive the lifting transfer line body 9 to descend, and the lifting transfer line bodies 9 on the first dispensing machine 3 and the second dispensing machine 4 also descend to be flush with the lifting transfer line body 9 on the first pallet elevator 2. In this way, it can be ensured that the line body pallet 10 passes under the line body pallet 10 being dispensed on the first dispensing machine 3 and is transferred to the lifting transfer line body 9 of the second dispensing machine 4 for dispensing. Thus, the first dispensing machine 3 and the second dispensing machine 4 can work simultaneously, improving the production capacity and efficiency of the dispensing process. The horizontal transfer line body 8 on the other side of the elevator lower frame assembly 21 is for the return transfer of the empty line body pallet 10.

[0059] Referring to Figure 7 , the elevator slide table 22 includes a lift table base 221, a lead screw assembly 222, a slide table connecting plate 2231201, and a lift table reinforcement plate 224. The lead screw assembly 222 is installed on the lift table base 221. The slide table connecting plate 2231201 is slidably connected to the lift table base 221. The lift table reinforcement plate 224 is connected to the slide table connecting plate 2231201. A line body rear mounting plate 225 connected to the lifting transfer line body 9 is installed on the lift table reinforcement plate 224, and the stable lifting and lowering of the lifting transfer line body 9 is achieved through the lift slide table. The second pallet elevator 5 has the same structure as the first pallet elevator 2, so the structure of the second pallet elevator 5 will not be described in detail.

[0060] As Figure 8As shown, in some embodiments, the first dispensing machine 3 includes a lower frame assembly 31 of the dispensing machine, a dispensing mechanism 32, a glue discharging mechanism 33, and a glue wiping mechanism 34.

[0066] Such as Figure 13 and Figure 14As shown, in some embodiments, the laminating machine 6 includes a laminating motion mechanism 61 and a flipping mechanism 62. The laminating motion mechanism 61 is connected to the flipping mechanism 62. The flipping mechanism 62 includes a flipping drive assembly 621 and a suction cup fixing plate 622. The suction cup fixing plate 622 is connected to a flipping shaft 623 on the flipping drive assembly 621. A number of suction cup assemblies 624 and electromagnetic suction assemblies 625 are installed on the suction cup fixing plate 622. The suction cup assemblies 624 can pass through the glass component to adsorb the glass component by the pressure maintaining fixture pressing plate 1032 and the pressure maintaining fixture positioning plate 1033 on the glass component receiving table 103. The electromagnetic suction assemblies 625 can adsorb the pressure maintaining fixture pressing plate 1032 and the pressure maintaining fixture positioning plate 1033. When the line tray 10 is transferred to the laminating machine 6, the laminating motion mechanism 61 drives the flipping mechanism 62 to move below the glass component. The glass component is held by the suction cup assemblies 624, and the electromagnetic suction assemblies 625 adsorb the pressure maintaining fixture pressing plate 1032 and the pressure maintaining fixture positioning plate 1033 and then flip to make the glass component fit with the middle frame component. The laminated glass component and the middle frame component are provided with the pressure maintaining fixture pressing plate 1032 and the pressure maintaining fixture positioning plate 1033, so as to ensure the laminating effect.

[0067] As Figure 14 and Figure 15 shown, in some embodiments, the laminating motion mechanism 61 includes an X-axis motion module 611, a Y-axis motion module 613, and a Z-axis motion module 612.

The Z-axis motion module 612 is connected to a sliding bottom plate 101614. The flipping mechanism 62 is connected to the sliding bottom plate 101614. The X-axis motion module 611 can drive the Z-axis motion module 612 to move along the horizontal left-right direction. The connection between the flipping mechanism 62 and the Z-axis motion module 612 is realized through the sliding bottom plate 101614. The Z-axis motion module 612 can drive the flipping mechanism 62 to move along the vertical direction. The Y-axis motion module 613 can drive the X-axis motion module 611 to move along the horizontal front-back direction, so as to adjust the position of the flipping mechanism 62 from multiple directions.

[0068] As Figure 13 and Figure 16As shown, in some embodiments, the laminating machine 6 further includes a laminating lower frame assembly 63 and a laminating lifting mechanism 64. The laminating lifting mechanism 64 is installed on the laminating lower frame assembly 63. The laminating lifting mechanism 64 includes a tray lifting platform 641 and a rotary deviation rectifying platform 642. The tray lifting platform 641 is used for secondary positioning of the line body tray 10, and the rotary deviation rectifying platform 642 is used for deviation rectification of the line body tray 10. After the tray lifting platform 642 secondarily positions the line body tray 10, it lifts the line body tray 10. The rotary deviation rectifying platform 642 can automatically rectify the receiving platform 102 of the middle frame assembly. Here, the deviation rectifying platform is a conventional deviation rectifying platform and will not be described in detail. It cooperates with the vision mechanism above the line body tray 10 to ensure the stability and accuracy of the lamination of the middle frame assembly and the glass assembly.

[0069] For the working principle and process of a vehicle-mounted central control screen laminating production line of the present utility model, the line body tray 10 at the starting position of the front-stage tray circulating machine 1 is loaded with a glass assembly and a middle frame assembly. The line body tray 10 is transferred to the position of the first tray elevator 2 through the horizontal transfer line body 8, and then the line body tray 10 is transferred to the first dispensing machine 3 or the second dispensing machine 4 through the lifting transfer line body 9 on the first tray elevator 2 for dispensing the glass assembly. After that, it is transferred to the second tray elevator 5 through the lifting transfer line body 9 on the first dispensing machine 3 or the second dispensing machine 4, and then the line body tray 10 is transferred to the laminating machine 6 through the lifting transfer line body 9 on the second tray elevator 5.

[0070] When the first dispensing machine 3 is dispensing, after the line body tray 10 loaded with the glass assembly and the middle frame assembly is transferred to the lifting transfer line body 9 on the first tray elevator 2, the elevator slide 22 can drive the lifting transfer line body 9 to descend, and the lifting transfer line bodies 9 on the first dispensing machine 3 and the second dispensing machine 4 also descend to be flush with the lifting transfer line body 9 on the first tray elevator 2. In this way, it can be ensured that the line body tray 10 passes under the line body tray 10 being dispensed on the first dispensing machine 3 and is transferred to the lifting transfer line body 9 of the second dispensing machine 4 for dispensing.

[0071] When the line body tray 10 is transferred to the laminating machine 6, the laminating motion mechanism 61 drives the flipping mechanism 62 to move under the glass assembly, sucks the glass assembly through the suction cup assembly 624, and the electromagnetic suction assembly 625 adsorbs the pressure maintaining fixture pressing plate 1032 and the pressure maintaining fixture positioning plate 1033 and then flips to align and laminate the glass assembly with the middle frame assembly. During this process, the tray lifting platform 642 will secondarily position the line body tray 10 and then lift the line body tray 10, and the rotary deviation rectifying platform 642 can automatically rectify the receiving platform 102 of the middle frame assembly, thereby ensuring the accuracy and stability of the lamination of the glass assembly and the middle frame assembly, and further ensuring the lamination quality.
