Description

TECHNICAL FIELD

In order to meet the dual demands of consumers for the aesthetics and practicability of the vehicle-mounted screen, the vehicle-mounted display screen is developing towards large size, high resolution and extremely narrow frame. At the same time, the IP67 level waterproof and dustproof performance gradually becomes the basic requirement of the vehicle-mounted display screen to cope with the challenges of the complex environment in the vehicle. However, since the vehicle-mounted panel usually adopts a multi-layer structure including a panel, a backlight, a middle frame and a rear shell and the like, the traditional assembling method faces significant limitations in realizing the narrow frame design, especially in balancing the precision and stability of the assembling process while maintaining the structural strength and protection performance.

[0003] The existing assembling device and assembling method for the vehicle-mounted panel usually realize the connection and fixation of the components by adopting a panel with a flexible printed circuit board (FPC) to wrap the flexible printed circuit board along the edge of the panel around the backlight light-emitting area, pass through the middle frame and finally be covered by the rear shell. However, since the vehicle-mounted panel is composed of multiple layers of structure and the backlight light-emitting area cannot be opened, the assembling device can only assemble the FPC through the middle frame and then the rear shell, thus making the frame of the existing vehicle-mounted display screen relatively wide and thick.

[0047] The arm lifting mechanism 200 includes a vacuum suction platform 201 disposed above the vacuum movable platform 102. A plurality of suction nozzles 202 are fixedly disposed on one side of the vacuum suction platform 201. The vacuum suction platform 201 is used to suck the panel 6, and the suction nozzles 202 are used to suck the flexible circuit board 7, wherein the flexible circuit board 7 is fixedly connected to one side of the panel 6.

When the two clamping arms 311 are close to and abut against each other, the clamping assembly 301 clamps a number of the flexible circuit boards 7. The first rotating driving member 302 drives the clamping assembly 301 to rotate so that the flexible circuit boards 7 are vertically inserted into the through holes 5 for assembly of the panel 6 and the backlight panel 4.

[0049] In the above embodiment, the mobile platform mechanism 100 comprises a first linear motor 101 and a vacuum mobile platform 102 fixed at the driving end of the first linear motor 101.

[0050] The arm moving mechanism 200 comprises a vacuum suction platform 201 arranged above the vacuum mobile platform 102, and the vacuum suction platform 201 sucks the panel 6 and the flexible circuit board 7 through a suction nozzle 202. The number and layout of the suction nozzles 202 are set according to actual needs to ensure that multiple flexible circuit boards 7 can be sucked at the same time. The suction platform is fixedly connected with the panel 6 and the flexible circuit board 7 through vacuum adsorption force, ensuring the stability of the components during the moving process and avoiding affecting the assembly precision due to position deviation.

The clamping assembly 301 comprises two clamping arms 311 arranged symmetrically, which can clamp the flexible circuit board 7 when the two arms are close to each other. When the clamping assembly 301 clamps the flexible circuit board 7, the clamping arms 311 ensure the stable position of the flexible circuit board 7, so that it can be accurately inserted in the vertical direction. The first rotary driving member 302 drives the clamping assembly 301 to rotate, and the flexible circuit board 7 is inserted into the insertion hole 5 of the backlight plate 4 in the vertical direction, completing the assembly of the flexible circuit board 7 and the backlight plate 4.

[0052] The vacuum suction platform 201 sucks the panel 6 and the flexible circuit board 7 fixed on one side of the panel 6 through the suction nozzle 202, and moves the panel 6 and the flexible circuit board 7 as a whole to the position of the backlight plate 4. The mobile platform mechanism 100 drives the backlight plate 4 to move to the working position, ensuring that the relative position of the backlight plate 4 and the panel 6 is correct. Then, the clamping assembly 301 drives the clamping arms 311 to clamp the flexible circuit board 7 through the rotary driving member, accurately inserts the flexible circuit board 7 into the insertion hole 5 of the backlight plate 4 in the vertical direction, and ensures the firm connection between the backlight plate 4, the panel 6 and the flexible circuit board 7.

[0053] In summary, the flexible circuit board 7 and the panel 6 in the application are set as a whole in advance, the flexible circuit board 7 is vertically inserted into the insertion hole 5 of the backlight plate 4 by using the clamping assembly 301, the limitation that the flexible circuit board 7 needs to pass through the middle frame in the traditional assembly mode is effectively avoided, the wiring path of the flexible circuit board 7 is simplified, the space required by the edge of the panel 6 is reduced, and therefore the frame width of the display screen is significantly reduced; the accurate positioning of the backlight plate 4 and the panel 6 is realized by cooperation of the vacuum moving platform 102 and the vacuum suction platform 201, the consistency of the assembly of components is improved; the clamping assembly 301 clamps the flexible circuit board 7 through the symmetrically arranged clamping arms 311, and the clamping assembly 301 is driven to rotate by the first rotary driver, so that the flexible circuit board 7 completes the vertical insertion operation into the insertion hole 5, the assembly efficiency is significantly improved, and the possibility of manual intervention steps and errors is reduced; in addition, the modularity of the equipment enhances the adaptability to different specifications of vehicle-mounted display screens, and has good universality and flexibility.

[0054] Reference Figure 4 In an embodiment, the moving platform mechanism 100 further comprises a plurality of clamping jaws 103 arranged on one side of the vacuum moving platform 102, the working end of the clamping jaw 103 faces the insertion hole 5, and the clamping surface of the clamping jaw 103 is parallel to the insertion hole 5.

[0055] The plurality of clamping jaws 103 are fixedly connected with the driving end of the downward pulling driving assembly, so that after the flexible circuit board 7 is vertically inserted into the insertion hole 5, the downward pulling driving assembly drives the clamping jaw 103 to pull down the flexible circuit board 7.

[0056] The downward pulling driving assembly comprises a fixed frame 104, the fixed frame 104 is fixedly connected with the vacuum moving platform 102, and the end face of the fixed frame 104 away from the vacuum moving platform 102 is provided with a downward pulling guide rail 105, the pulling frame 106 is slidably connected with the downward pulling guide rail 105, and the end of the pulling frame 106 close to the vacuum moving platform 102 is fixedly connected with the plurality of clamping jaws 103.

[0057] The end of the pulling frame 106 away from the vacuum moving platform 102 is provided with a driving block 107, the downward pulling lead screw 108 is threadedly connected in the driving block 107, one end of the downward pulling lead screw 108 is fixedly connected with the driving end of the downward pulling motor 109, and the downward pulling motor 109 is fixedly arranged on the end face of the fixed frame 104 away from the vacuum moving platform 102.

[0058] In the above embodiment, the working end of the clamping jaw 103 is directed towards the insertion hole 5 on the backlight plate 4, and the clamping surface of the clamping jaw 103 is parallel to the insertion hole 5. In this way, when the flexible circuit board 7 is vertically inserted into the insertion hole 5 through the clamping assembly 301, the clamping jaw 103 can accurately clamp the flexible circuit board 7, preventing displacement or loosening in subsequent operations. The clamping jaw 103 is fixedly connected to the driving end of the pull-down driving assembly, which can accurately pull down the flexible circuit board 7 to a predetermined position after it is inserted into the insertion hole 5, ensuring the secure and reliable connection between the flexible circuit board 7 and the backlight plate 4 and the panel 6.

[0059] The pull-down driving assembly is composed of a fixed frame 104, a pull-down guide rail 105, a pulling frame 106, and a pull-down motor 109. The fixed frame 104 is fixedly connected to the vacuum moving platform 102, ensuring that the entire driving system maintains a consistent positional relationship with the moving platform. The end surface of the fixed frame 104 away from the vacuum moving platform 102 is provided with the pull-down guide rail 105, and the pulling frame 106 is slidingly connected to the pull-down guide rail 105 through the pull-down guide rail 105. The pulling frame 106 has the clamping jaw 103 fixedly connected to one end thereof close to the vacuum moving platform 102. When the flexible circuit board 7 is clamped and inserted into the insertion hole 5, the clamping jaw 103 on the pulling frame 106 is connected to the pull-down lead screw 108, which can accurately pull down the flexible circuit board 7 under the drive of the pull-down motor 109, ensuring that its correct position does not deviate. The pull-down motor 109 is connected to the pull-down lead screw 108 through the driving block 107. The rotation of the lead screw drives the pull-down action of the clamping jaw 103, achieving accurate positioning of the flexible circuit board 7.

[0060] In an example, the driving end of the clamping jaw 103 is provided with a detection optical fiber 110, one end of the detection optical fiber 110 is flush with the clamping surface of the clamping jaw 103, and the detection optical fiber 110 is used to detect whether the clamping jaw 103 clamps the flexible circuit board 7;

[0061] The upper end surface of the vacuum moving platform 102 is provided with a pressure sensor 111, and the sensing end of the pressure sensor 111 abuts against the bottom end of the backlight plate 4.

[0062] In the above embodiment, the driving end of the clamping jaw 103 is provided with a detection optical fiber 110, one end of the detection optical fiber 110 is flush with the clamping surface of the clamping jaw 103, and the detection optical fiber 110 is used to detect whether the clamping jaw 103 clamps the flexible circuit board 7. When the clamping jaw 103 approaches the flexible circuit board 7, the detection optical fiber 110 feeds back whether the flexible circuit board 7 is successfully clamped through the change of optical signal. If clamping failure is detected, the system can timely issue an alarm or stop subsequent operations, ensuring that the flexible circuit board 7 will not deviate or be damaged in the subsequent assembly process due to improper clamping.

[0063] In addition, to monitor the installation status of the backlight panel 4 on the vacuum movable platform 102 and the assembly force between the panel 6 and the backlight panel 4, a pressure sensor 111 is installed on the upper end surface of the vacuum movable platform 102. The sensing end of the pressure sensor 111 contacts the bottom end of the backlight panel 4. By monitoring the changes in the pressure applied by the backlight panel 4 on the platform in real time, it is determined whether the backlight panel 4 is in the correct position and the correct assembly posture. If the backlight panel 4 does not fully fit the platform, the pressure sensor 111 will promptly feedback an abnormal signal, prompting the operator to make adjustments or the system to automatically correct it, thereby ensuring that the backlight panel 4 is installed smoothly and does not affect the subsequent assembly with the flexible circuit board 7 and the panel 6.

[0064] refer to Figure 5 In one embodiment, the arm moving mechanism 200 also includes a fixed welding frame 203, which is mounted on two opposite sides of the first linear motor 101. The upper end surface of the fixed welding frame 203 is provided with a second linear motor 204, and the second linear motor 204 is perpendicular to the first linear motor 101 in the horizontal direction.

[0066] In the above embodiment, the fixed welding frame 203 is set up on two opposite sides of the first linear motor 101 to provide support for the second linear motor 204 and its related mechanisms. The driving direction of the second linear motor 204 is perpendicular to the first linear motor 101, so that the vacuum suction platform 201 can achieve two-way movement in the horizontal direction, further expanding the operating range of the vacuum suction platform 201 and improving the flexibility and assembly adaptability of the equipment. The driving end of the second linear motor 204 is slidably connected to the vacuum suction platform 201 and realizes vertical movement through the first lifting unit 205. The first lifting unit 205 is connected to the first lifting drive member 206.

[0067] In addition, the driving end of the first lifting unit 205 is fixedly connected with a second rotary driving member 207, and the driving end of the second rotary driving member 207 is fixedly connected with the vacuum suction platform 201. This design enables the vacuum suction platform 201 to rotate in the plane, further improving the precise positioning capability of the equipment.
