[0043] During the assembly process of some in-vehicle display screens, the housing and screen mold need to be assembled. During assembly, the FPC cable on the screen is threaded through the holes in the housing, and then the housing and screen mold are bonded together using glue. Currently, manual assembly of the housing and screen is generally performed. Manual assembly is inefficient, time-consuming, and affects the adhesive strength of the glue. The glue is easily damaged during the assembly process, resulting in poor reliability of the housing and screen assembly.

[0044] In view of this, the present invention proposes an in-vehicle display screen assembly device, which realizes the transfer of the shell through the loading tray, the screen is picked up by the robot arm, the FPC cable is clamped by the clamping part, and the FPC cable is threaded through the air blown out of the guide air hole, thereby replacing the manual bonding assembly of the screen and the shell. It is highly efficient, time-saving, reduces the impact on the adhesive force of the glue, and is not easily damaged during the assembly process, thereby ensuring the reliability of the shell and screen assembly. Figures 1 to 6 FIG. 1 is an embodiment of the vehicle display screen assembly device provided by the present invention.

[0045] like Figure 1 and Figure 2As shown, the vehicle-mounted display screen assembly device 100 proposed by the present invention includes a base 1, a loading tray 2, a robotic arm 3 and a clamping mechanism 4. The base 1 is provided with a loading station and an assembly station arranged in sequence along the circumferential direction; the loading tray 2 is rotatably mounted on the base 1 along an axis extending in the vertical direction, and at least two loading molds 21 are arranged on the circumference of the loading tray 2. The upper end surface of each loading mold 21 is used to mount the housing 200. Under the rotation of the loading tray 2, each loading mold 21 can be in a position to be positioned in sequence. The loading station and the assembly station, and the at least two loading molds 21 are respectively stopped at the loading station and the assembly station; the robot arm 3 is used to pick up the screen 300 so that the FPC cable is located above the penetration hole; the clamping mechanism 4 is formed with a clamping part 41, and the clamping part 41 can be moved to the assembly station to clamp the FPC cable. The clamping part 41 is provided with a guide air hole 422, which is used to make the FPC cable pass through the penetration hole under gas pressure.

[0046] In the technical solution of the present invention, when assembling the screen 300 and the shell 200 of the vehicle-mounted display screen, the loading tray 2 moves the shell 200 to the assembly station. At this time, the robotic arm 3 picks up the screen 300 and moves it above the shell 200, so that the FPC cable is above the penetration hole. Then the clamping part 41 moves to the assembly station to clamp the FPC cable, and the guide air hole 422 blows out high-pressure gas so that the FPC cable is penetrated into the penetration hole under gas pressure. In this way, after the clamping part 41 releases the FPC cable and moves away from the assembly station, the robotic arm 3 moves downward to bond the screen 300 to the shell 200. The shell 200 is transferred through the loading tray 2, the robot arm 3 picks up the screen 300, the clamping part 41 clamps the FPC cable, and the air blown out of the guide air hole 422 is used to thread the FPC cable, thereby replacing the manual bonding and assembly of the screen 300 and the shell 200. This is efficient, time-saving, reduces the impact on the adhesive force of the glue, and is not easy to damage the glue during the assembly process, thereby ensuring the assembly reliability of the shell 200 and the screen 300.

[0047] In this embodiment, if Figures 1 to 3As shown, each of the loading molds 21 is provided with a mounting hole 211 extending in the vertical direction, the mounting hole 211 is used to accommodate the housing 200, and the inner wall surface of the mounting hole 211 is concave to form two avoidance grooves 212, and the two avoidance grooves 212 are spaced and arranged opposite to each other; a through hole is provided on the loading plate 2 corresponding to the loading mold 21, and the through hole is connected to the mounting hole 211; the vehicle-mounted display assembly device 100 also includes a clamping mechanism 7, the clamping mechanism 7 includes a parallel air claw structure 71, a first driving cylinder 72, and the parallel air claw structure 7 1 includes two movable claws 711 extending in the vertical direction and arranged opposite to each other, and the two movable claws 711 have a first state in which they are separated from each other and a second state in which they are close to each other; the first driving cylinder 72 is provided at the assembly station and is correspondingly located below the loading mold 21 of the assembly station. The cylinder rod of the first driving cylinder 72 is drivingly connected to the parallel air claw structure 71, and is used to drive the parallel air claw structure 71 to move up and down, so that the two movable claws 711 in the first state are respectively extended into the two avoidance grooves 212. After the loading mold 21 rotates to the assembly station, the two movable claws 711 are in the first state, that is, the two movable claws 711 are open away from each other, and then the first driving cylinder 72 works, and the cylinder rod of the first driving cylinder 72 extends to push the parallel air claw structure 71 to move upward, thereby causing the two movable claws 711 to extend into the two avoidance grooves 212 respectively. In this way, the two movable claws 711 approach each other to achieve the clamping limit of the shell 200, and place the shell 200 and the screen 300 for movement during assembly. It should be noted that the parallel air claw structure 71 is an existing translational type clamp. The specific model of the parallel air claw structure 71 is not limited, as long as it can achieve the clamping of the shell 200. In this application, the parallel air claw structure 71 is a translational type clamp of the MHL2 series.

[0048] In order to prevent the housing 200 from shifting during the rotation of the loading plate 2, the loading mold 21 is provided with a limiting structure. Figure 4 As shown, the upper end surface of each loading mold 21 is provided with a plurality of grooves 213. The grooves 213 are spaced apart along the periphery of the mounting hole 211 and are configured to engage with protrusions provided on the housing 200. The grooves 213 are provided on the upper end surface of the loading mold 21. Thus, when the housing 200 is placed on the loading mold 21, the grooves 213 can engage with the protrusions provided on the housing 200, thereby limiting the position of the housing 200 and preventing the housing 200 from shifting during the rotation of the loading tray 2.

[0049] In this embodiment, if Figure 2 、 Figure 5 and Figure 6 As shown, the clamping mechanism 4 includes an air gripper structure 42, and the air gripper structure 42 includes two movable air grippers 421 extending in the left and right directions and arranged side by side. The two movable air grippers 421 can separate from and approach each other to clamp or release the FPC cable. The lower end surface of each movable air gripper 421 is provided with the guide air hole 422; the clamping portion 41 includes two movable air grippers 421. After the robotic arm 3 moves the screen 300 above the housing 200, the two movable air grippers 421 separate and open. The two movable air grippers 421 then move to the assembly station and are positioned between the housing 200 and the screen 300. Thus, the two movable air grippers 421 approach each other to clamp the FPC cable. At this point, the guide air holes 422 on the two movable air grippers 421 blow out high-pressure gas, causing the FPC cable to pass through the passage holes under the gas pressure. This enables automatic threading of the FPC cable during assembly of the housing 200 and the screen 300, thereby improving assembly efficiency. It should be noted that the air gripper structure 42 is an existing translational gripper. The specific model of the air gripper structure 42 is not limited, as long as it can clamp the FPC cable. In this application, the air gripper structure 42 is an MHL2 series translational gripper. It should be noted that an air compressor can be provided to provide high-pressure gas to the guide air holes 422.

[0050] In this embodiment, if Figure 6 As shown, each movable air gripper 421 is provided with an air inlet channel 423 extending in the left-right direction. The air inlet channel 423 is connected to the guide air hole 422. The guide air hole 422 is arranged at an angle, gradually approaching the clamping surface of the movable air gripper 421 from top to bottom. Because the guide air holes 422 are arranged at an angle, gradually approaching the clamping surface of the movable air gripper 421 from top to bottom, the high-pressure gas in the air inlet channel 423 passes through the guide air hole 422 and is blown toward the portion of the FPC cable located below the two movable air grippers 421, thereby allowing the FPC cable to pass through the through-hole in the housing 200.

[0051] In this embodiment, if Figure 5As shown, the clamping mechanism 4 also includes a mounting seat 43, a first connecting seat 44 is provided between the mounting seat 43 and the clamping portion 41, and a second connecting seat 45 is provided between the first connecting seat 44 and the clamping portion 41; the first connecting seat 44 is movably mounted on the mounting seat 43 in the front-to-back direction; the second connecting seat 45 is movably mounted on the first connecting seat 44 in the left-to-right direction; and the clamping portion 41 is movably mounted on the second connecting seat 45 in the up-to-down direction. By providing the first connecting seat 44 and the second connecting seat 45, the clamping portion 41 can be moved in the up-to-down direction and the left-to-right direction. Since the clamping portion 41 is movably mounted on the second connecting seat 45 in the up-to-down direction, the clamping portion 41 can also be moved in the up-to-down direction. In this way, the position of the clamping portion 41 can be flexibly adjusted according to actual needs, thereby making the use of the clamping mechanism 4 more convenient.

[0052] Specifically, in this embodiment, Figure 5 As shown, one of the mounting base 43 and the first connecting base 44 is provided with a first slide rail 431, and the other is provided with a first slide groove adapted to the first slide rail 431.

The clamping mechanism 4 also includes a second driving cylinder 46, the cylinder rod of which is connected to the first connecting base 44. The first slide rail 431 cooperates with the first slide groove to enable the first connecting base 44 to move forward and backward on the mounting base 43. The second driving cylinder 46 provides the driving force for the movement of the first connecting base 44, which is convenient and labor-saving.

[0053] Specifically, in this embodiment, Figure 5 As shown, one of the first connecting seat 44 and the second connecting seat 45 is provided with a second slide rail 441, and the other is provided with a second slide groove adapted to the second slide rail 441, and the second slide rail 441 is extended in the left-right direction; the clamping mechanism 4 also includes a rodless cylinder 47, which is provided in the left-right direction on the first connecting seat 44, and the piston of the rodless cylinder 47 is connected to the second connecting seat 45.

The clamping portion 41 is connected to the slider of the servo electric cylinder 48 so that the servo electric cylinder 48 provides a driving force for the clamping portion 41, thereby reducing the effort required to move the clamping portion 41.

[0055] In this embodiment, if Figure 1 As shown, the vehicle-mounted display assembly device 100 further includes a reducer 5 and a drive motor 6.
