[0040] An entry and exit groove 29 is formed through the side wall of the base 1, and electric push rods 30 are symmetrically fixed on both side walls of the base 1. A docking frame 31 is slidably connected in the entry and exit groove 29. The output end of the electric push rod 30 is fixedly connected to the end of the docking frame 31, and the other end of the docking frame 31 is rotatably connected to a rotating frame 32 at the bottom. A torsion spring is provided at the rotation connection between the rotating frame 32 and the docking frame 31, and a docking roller 33 is rotatably connected to the bottom of the rotating frame 32.

[0041] A cover shell 19 is provided on the top of the base 1, and a conveyor belt 20 is installed on the inner wall of the cover shell 19. A buffer sleeve 21 is fixedly installed at equal intervals on the outer side of the conveyor belt 20. A buffer rod 22 is slidably connected inside the buffer sleeve 21. A compression spring is provided inside the buffer sleeve 21. Both ends of the compression spring are fixedly connected to the buffer rod 22 and the inside of the buffer sleeve 21 respectively. One end of the buffer rod 22 located outside the buffer sleeve 21 is fixedly connected to a buffer rubber disc.

[0042] The through groove 2 and the outer side wall of the cover 19 are both provided with mounting grooves, and an ultrasonic generator 23 is fixedly installed in the mounting groove of the through groove 2. It should be explained here that the ultrasonic generator 23 is an existing mechanism, and the ultrasonic wave emitted by the ultrasonic generator 23 is used to exert a vibration effect on the glue poured on the top of the vehicle display screen housing, so that the glue flows in a small range and multiple positions, thereby further promoting the glue to closely fit the display screen and the vehicle display screen housing, avoiding the problem of glue leakage, and affecting the subsequent normal use of the vehicle display screen. A fan 24 is fixedly installed in the mounting groove of the cover 19;

[0043] A motor 25 for driving the rocker 101 to rotate is fixedly installed on the outer side of the support frame 903. A threaded rod 27 and a guide rod are respectively arranged inside the two slide grooves 3. Both ends of the threaded rod 27 are movably connected to the inner wall of the corresponding slide groove 3 through bearings. Both ends of the guide rod are fixedly connected to the inner wall of the corresponding slide groove 3. A motor 28 for driving the threaded rod 27 to rotate is arranged on the outer side of the base 1. A threaded groove and a guide groove matching the threaded rod 27 and the guide rod are opened on the outer side of the slide plate 4.

[0044] When setting up specifically, the vehicle-mounted display screen housing is placed in the placement slot 5 at the top of the slide plate 4, and then the electric push rod 4 30 is started, and the electric push rod 4 30 drives the docking frame 31 to slide in the inlet and outlet slot 29 until the docking frame 31 is pushed out of the inlet and outlet slot 29. Figure 1 The four electric push rods 4 30 shown are arranged as a group of two electric push rods 4 30 respectively on the two side walls of the base 1, so that the four electric push rods 4 30 are arranged at the four corners of the vehicle-mounted display screen housing.

[0045] Under the action of the electric push rod 4 30, the docking frame 31 contacts the corner of the vehicle display screen shell through the docking roller 33. When the docking roller 33 contacts the vehicle display screen shell, the docking frame 31 will rotate. The four docking frames 31 use the docking rollers 33 to calibrate the position of the four corners of the vehicle display screen shell, so that the vehicle display screen shell is always in the correct position when placed in the placement slot 5. The four docking frames 31 release the contact with the vehicle display screen shell and return to the initial state under the action of the torsion spring, so as to re-enter the entry and exit slot 29. Then the lifting cylinder 7 is started again, and the lifting cylinder 7 drives the lifting plate 6 to rise until the pneumatic suction cup 8 contacts the bottom of the vehicle display screen shell, and then the pneumatic suction cup 8 is used to adsorb and fix the bottom of the vehicle display screen shell to avoid the problem of position deviation of the vehicle display screen shell during horizontal transportation.

[0046] The vehicle-mounted display screen is then placed in the support slot 14 on the top of the support frame 13. It should be noted here that the spacing between the two support frames 13 and the setting of the support slot 14 are matched with the size of the current vehicle-mounted display screen, so that the vehicle-mounted display screen is placed in the support slot 14 and is just snapped into the two support slots 14, thereby achieving rapid placement and rapid position calibration of the vehicle-mounted display screen.

[0047] Embodiment 2: Figure 1-Figure 9As shown, the flip assembly 10 includes a rocker 101 and a rocker block 102, one end of the rocker 101 is rotatably connected to the side wall of the support frame 3 903, the rocker block 102 is rotatably connected to the other end of the rocker 101, the outer side of the support frame 3 903 is fixedly connected to the auxiliary bracket 11, the outer side of the auxiliary bracket 11 is movably connected to the rotating shaft 103 through a bearing, one end of the rotating shaft 103 is fixedly connected to the swing rod 104, and one end of the swing rod 104 is rotatably connected to the swing block 117;

[0048] The bottom of the side wall of the support frame three 903 is rotatably connected with a linkage rod 105, and the side wall of the linkage rod 105 is provided with a driving groove 106 and a driving groove 2 107, the rocking block 102 is slidably connected in the driving groove 106, the swing block 117 is slidably connected in the driving groove 2 107, and the end of the rotating shaft 103 away from the swing rod 104 is fixed with a connecting block 108 by spot welding, one side of the connecting block 108 is fixedly connected with a connecting block 2 109, and the other side of the connecting block 108 is fixedly connected with an electric push rod 110, and the output end of the electric push rod 110 is fixedly connected with a support plate 111, and a synchronous cross bar 26 is fixedly connected between the two connecting blocks 108.

[0049] In the specific setting, the motor 28 drives the threaded rod 27 to rotate, and the slide plate 4 slides horizontally along the slide groove 3 under the action of the threaded rod 27 until the vehicle display screen housing moves to the bottom of the support frame 1 901, and then the electric push rod 3 16 drives the glue spraying tube 17 to descend through the partition until the glue spraying tube 17 moves close to the top of the vehicle display screen housing. Figure 5 As shown, the shape design of the glue spraying tube 17 matches the shape of the vehicle display screen shell, which is convenient for full glue injection to the vehicle display screen shell. After the glue spraying tube 17 injects glue to the top of the vehicle display screen shell, the slide plate 4 drives the vehicle display screen shell after injection to continue to move. When passing through the ultrasonic generator 23, the ultrasonic generator 23 applies vibration to the glue on the top of the vehicle display screen shell. This makes the glue flow in a small range and multiple positions, so that the glue on the top of the vehicle display screen shell is evenly distributed.

[0050] When the vehicle-mounted display screen shell moves to the bottom of the vehicle-mounted display screen, the electric push rod 110 drives the pneumatic suction cup 2 112 to rise through the support plate 111 until the pneumatic suction cup 2 112 contacts and fixes the bottom of the vehicle-mounted display screen with adsorption, and the pneumatic suction cup 2 112 is used to fix the vehicle-mounted display screen to avoid the problem of the vehicle-mounted display screen shaking during transportation.

[0051] Start motor 25, which drives rocker 101 to rotate. In the process of circular rotation, rocker 101 cooperates with rocking block 102 and driving slot 1 106, thereby driving linkage rod 105 to deflect. In the process of deflection, linkage rod 105 cooperates with swing block 117 and driving slot 2 107, thereby driving swing rod 104 to deflect synchronously. In the process of deflection, swing rod 104 drives rotating shaft 103 to rotate synchronously. In the process of rotation, rotating shaft 103 drives connecting block 108 to rotate synchronously. Connecting block 2 109 deflects relative to sleeve 2 116 under the synchronous action of connecting block 108. Sleeve 2 116 slides back and forth along slide rod 2 115 under the action of connecting block 2 109. Slide rod 2 115 drives sleeve 1 114 to slide back and forth in slide rod 1 113 during sliding.

[0052] The pneumatic suction cup 112 drives the vehicle display screen to deflect 90 degrees under the action of the flip assembly 10 until the vehicle display screen is located directly above the vehicle display screen housing. The electric push rod 110 drives the vehicle display screen to be accurately placed in the groove at the top of the vehicle display screen housing. The pneumatic suction cup 112 releases the adsorption of the vehicle display screen at this time, and then the slide plate 4 continues to move to the conveyor belt 1 20 under the action of the threaded rod 27;

[0053] It should be noted here that if Figure 8 As shown, a conveyor belt 2 is provided at the bottom of the inner wall of the base 1, and a clamping claw is installed on the side wall of the through slot 2 located below the cover 19. The clamping claw is an existing mechanism, which is used to take the assembled vehicle display screen module out of the placement slot 5 at the top of the slide plate 4 and place it on the top of the conveyor belt 2 for transmission. The conveyor belt 2 drives the assembled vehicle display screen module to move below the conveyor belt 1 20, and then the buffer rod 22 on the outside of the conveyor belt 1 20 presses against the top of the vehicle display screen module through the buffer rubber disc, and the fan 24 accelerates the air flow inside the cover 19. The fast-flowing air can take away the solvent vapor volatilized from the surface of the glue, reduce the solvent concentration around the glue, and thus promote the drying of the glue;

[0054] At the same time, the buffer rod 22 presses the vehicle display screen module during transportation, further ensuring full contact of the glue, so that the glue between the vehicle display screen and the vehicle display screen housing is evenly distributed, filling small gaps, and promoting glue curing, providing pressure for the glue to accelerate chemical reactions or physical changes, and expelling possible bubbles to improve curing quality; at the same time, it can enhance the connection strength, make the combination tighter, and increase the adhesion of the glue to the surfaces of both.
