Description

Technical Field

[0002] In recent years, with the rapid development of the new energy vehicle market, the design and performance requirements of vehicle-mounted displays, as important terminals for in-vehicle information interaction, have been continuously improved. In order to meet consumers' dual demands for the aesthetics and practicality of vehicle-mounted screens, vehicle-mounted displays are developing in the direction of large size, high resolution and extremely narrow bezels. At the same time, IP67-level waterproof and dustproof performance has gradually become a basic requirement for vehicle-mounted displays to meet the challenges of complex in-vehicle environments. However, since vehicle-mounted panels usually adopt a multi-layer structure, including components such as panels, backlights, middle frames and rear shells, traditional assembly methods face significant limitations in achieving narrow bezel designs, especially while maintaining structural strength and protective performance. It is difficult to balance the precision and stability of the assembly process. The existing vehicle panel assembly equipment and assembly methods usually use a panel with a flexible printed circuit (FPC) to pass the flexible printed circuit along the edge of the panel around the backlight emitting area, pass through the middle frame and finally be covered by the back cover to achieve the connection and fixation of the components. However, since the vehicle panel is composed of a multi-layer structure and the backlight emitting area cannot be opened, the assembly equipment can only pass the FPC through the middle frame for assembly, which makes the frame of the existing vehicle display relatively wide and thick.

[0023] In the above embodiment, the moving platform mechanism 100 includes a first linear motor 101 and a vacuum moving platform 102 fixed at its driving end.

[0024] The arm-lifting mechanism 200 includes a vacuum suction platform 201 disposed above the vacuum moving platform 102, and the vacuum suction platform 201 sucks the panel 6 and the flexible circuit board 7 through the suction nozzle 202. The number and layout of the suction nozzle 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 to the panel 6 and the flexible circuit board 7 through vacuum adsorption force to ensure the stability of the components during the handling process and avoid affecting the assembly accuracy due to position offset.

[0025] The clamping mechanism 300 is arranged on one side of the vacuum suction platform 201, and the clamping assembly 301 is fixedly connected to it through a rotating drive. The clamping assembly 301 includes two symmetrically arranged clamping arms 311, 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 rotating drive member 302 drives the clamping assembly 301 to rotate, inserting the flexible circuit board 7 into the insertion hole 5 of the backlight panel 4 in the vertical direction, and completing the assembly of the flexible circuit board 7 and the backlight panel 4.

The mobile platform mechanism 100 drives the backlight panel 4 to move to the working position to ensure that the relative position of the backlight panel 4 and the panel 6 is correct. Then, the clamping assembly 301 drives the clamping arm 311 to clamp the flexible circuit board 7 through the rotating driving member, and accurately inserts the flexible circuit board 7 vertically into the insertion hole 5 of the backlight panel 4 to ensure that the connection between the backlight panel 4, the panel 6 and the flexible circuit board 7 is firm.

[0028] refer to Figure 4 In one embodiment, the mobile platform mechanism 100 further includes a plurality of clamping jaws 103 disposed on one side of the vacuum mobile platform 102, the working ends of the clamping jaws 103 face the insertion hole 5, and the clamping surfaces of the clamping jaws 103 are parallel to the insertion hole 5; The plurality of clamps 103 are fixedly connected to the driving end of the pull-down driving assembly, so that after the flexible circuit board 7 is vertically inserted into the insertion hole 5 , the pull-down driving assembly drives the clamps 103 to pull down the flexible circuit board 7 .

[0029] The pull-down drive assembly includes a fixed frame 104, the fixed frame 104 is fixedly connected to the vacuum moving platform 102, and a pull-down guide rail 105 is provided on one end of the fixed frame 104 away from the vacuum moving platform 102, and the pull-down guide rail 105 is slidably connected to a pulling frame 106, and one end of the pulling frame 106 close to the vacuum moving platform 102 is fixedly connected to a plurality of the clamps 103; A driving block 107 is provided at one end of the pulling frame 106 away from the vacuum moving platform 102, and a pull-down screw 108 is threadedly connected in the driving block 107. One end of the pull-down screw 108 is fixedly connected to the driving end of the pull-down motor 109. The pull-down motor 109 is fixedly arranged on an end surface of the fixed frame 104 away from the vacuum moving platform 102.

[0030] In the above embodiment, the working end of the clamp 103 faces the insertion hole 5 on the backlight panel 4, and the clamping surface of the clamp 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 clamp 103 can accurately clamp the flexible circuit board 7 to prevent displacement or loosening in subsequent operations. The clamp 103 is fixedly connected to the driving end of the pull-down driving assembly, and can accurately pull the flexible circuit board 7 down to a predetermined position after the flexible circuit board 7 is inserted into the insertion hole 5, ensuring that the connection between the flexible circuit board 7 and the backlight panel 4 and the panel 6 is firm and reliable.

[0031] The pull-down drive 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 mobile platform 102 to ensure that the entire drive system maintains a consistent positional relationship with the mobile platform. A pull-down guide rail 105 is provided on one end face of the fixed frame 104 away from the vacuum mobile platform 102, and the pulling frame 106 is slidably connected to the pull-down guide rail 105 through the pull-down guide rail 105. A clamp 103 is fixedly connected to one end of the pulling frame 106 close to the vacuum mobile platform 102. When the flexible circuit board 7 is clamped and inserted into the insertion hole 5, the clamp 103 on the pulling frame 106 is connected to the pull-down screw 108, and can accurately pull down the flexible circuit board 7 under the drive of the pull-down motor 109 to ensure 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 , and the rotation of the lead screw drives the pull-down action of the clamping jaw 103 , thereby realizing the precise positioning of the flexible circuit board 7 .

[0032] In one example, a detection optical fiber 110 is passed through the driving end of the clamping jaw 103, 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; A pressure sensor 111 is disposed on the upper end surface of the vacuum moving platform 102 , and a sensing end of the pressure sensor 111 abuts against the bottom end of the backlight plate 4 .

[0033] In the above embodiment, the driving end of the clamping jaw 103 is penetrated with a detection optical fiber 110, one end of which is flush with the clamping surface of the clamping jaw 103, and is used to detect in real time whether the clamping jaw 103 accurately clamps the flexible circuit board 7. When the clamping jaw 103 is close to the flexible circuit board 7, the detection optical fiber 110 feedbacks whether the flexible circuit board 7 is successfully clamped through the change of the optical signal. If a clamping failure is detected, the system can issue an alarm in time or stop subsequent operations to ensure that the flexible circuit board 7 will not be offset or damaged in the subsequent assembly process due to improper clamping.

[0034] In addition, in order to monitor the installation status of the backlight panel 4 on the vacuum mobile platform 102 and the assembly strength of the panel 6 and the backlight panel 4, a pressure sensor 111 is set on the upper end surface of the vacuum mobile platform 102. The sensing end of the pressure sensor 111 is in contact with the bottom end of the backlight panel 4. By real-time monitoring the pressure changes applied by the backlight panel 4 on the platform, it is determined whether the backlight panel 4 is in the correct position and the correct assembly posture. If the backlight panel 4 is not completely attached to the platform, the pressure sensor 111 will promptly feedback an abnormal signal to remind the operator to make adjustments or the system to automatically correct, 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.

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.

A driving belt 308 is provided at the end of the clamping support plate 307 away from the first rotating drive member 302. The driving belt 308 is transmission-connected to the driving end of the clamping drive member 309, and a clamping slider 310 is fixedly connected to the opposite ends of the driving belt 308 respectively. The clamping slider 310 is slidingly connected to the clamping support plate 307, and the two clamping arms 311 are fixedly connected to the two clamping sliders 310 respectively, wherein when the driving belt 308 is driven to rotate, the two clamping sliders 310 respectively drive the two clamping arms 311 to move in opposite directions.

The clamping slider 310 is slidably connected to the clamping support plate 307, and at the same time drives the two clamping arms 311 to move in opposite directions. When the driving belt 308 rotates, the two clamping arms 311 can approach or move away synchronously but in opposite directions, so as to accurately clamp or release the flexible circuit board 7. Not only does it ensure the stability of the clamping operation, but it also avoids the problem of bending or damage of the flexible circuit board 7 caused by the unilateral force of the clamping arm 311.

[0044] In general, this embodiment achieves high-precision, multi-directional clamping control of the flexible circuit board 7 through multi-dimensional adjustment components (the third linear motor 303, the fourth linear motor 304 and the second lifting unit 305) and optimizes the driving mode of the clamping component 301, ensuring the accurate positioning and stability of the flexible circuit board 7 during the assembly process, significantly improving the equipment's adaptability to complex assembly processes, and reducing operational errors, providing a strong guarantee for the high-quality assembly of vehicle-mounted display screens.

[0045] In one embodiment, it also includes a visual alignment component, which includes a visual alignment camera fixedly connected to the vacuum suction platform 201, the visual alignment camera faces the backlight panel 4, an alignment light source is arranged below the visual alignment camera, and an alignment control system is arranged on one side of the visual alignment camera, and the alignment control system is electrically connected to the visual alignment camera, the mobile platform mechanism 100, the arm moving mechanism 200 and the clamping mechanism 300 respectively, wherein the alignment control unit is used to receive the detection signal of the visual alignment camera, and control the movement of the mobile platform mechanism 100, the arm moving mechanism 200 and the clamping mechanism 300 according to the detection signal, so that after the backlight panel 4 is aligned with the panel 6, the flexible circuit board 7 is driven to be inserted into the insertion hole 5, so that the panel 6 and the backlight panel 4 are assembled.

[0046] In the above embodiment, the visual alignment component includes a visual alignment camera fixedly connected to the vacuum suction platform 201, which faces the backlight plate 4 and can capture the position and angle information of the backlight plate 4 and the panel 6 in real time.

[0047] During operation, the visual alignment camera collects the position information of the backlight panel 4 and related components, and transmits the detection signal to the alignment control system. The alignment control system processes the collected data, generates control instructions through precise calculation, and controls the movement of the mobile platform mechanism 100, the arm mechanism 200 and the clamping mechanism 300 respectively, so that the backlight panel 4 and the panel 6 are accurately aligned. At the same time, after the backlight panel 4 and the panel 6 are aligned, the alignment control system further coordinates the operation of the clamping mechanism 300 to ensure that the flexible circuit board 7 is inserted into the insertion hole 5 at the correct angle and position, thereby realizing the accurate assembly of the panel 6 and the backlight panel 4.

[0048] By introducing the visual alignment component, the equipment can sense the position of the components in the assembly process in real time and dynamically adjust the motion parameters of each mechanism, greatly reducing the errors caused by manual adjustment or mechanical deviation. The combination of the visual alignment camera and the alignment light source further improves the detection accuracy, ensuring that the assembly of complex multi-layer structured vehicle display screens meets high-precision requirements.
