Description

Technical Field

[0001] This invention relates to the field of screen inspection technology, specifically to an OGC multi-directional rotating appearance inspection device. Background Technology

[0002] Optical cover glass (OGC) is a core optical component in various terminal products such as consumer electronics, automotive displays, and smart home devices. Its appearance quality directly determines the user experience and production yield of the terminal products. The industry has stringent requirements for the appearance of OGC, specifying that its surface must be free of defects such as scratches, chipping, dirt, bubbles, and color differences. OGC is installed in front of the display panel, effectively providing protection, dust prevention, and optimizing optical display effects.

[0003] Currently, there are two main implementation methods for OGC appearance inspection in existing technologies: one is manual visual inspection, in which inspectors hold the OGC product and observe it from multiple angles to determine whether its appearance meets the standards; the other is fixed machine inspection device, which uses a fixture to fix the OGC to the inspection platform and uses a single-angle or dual-angle industrial camera to take images of the product to complete the appearance defect detection. This is the most widely used semi-automated inspection solution in the industry.

[0004] However, during the production of the electric folding ceiling screen for rear seats in vehicles, vehicle manufacturers explicitly require that the gold fingers of the flexible ribbon cable connector of the electric folding ceiling screen be covered and protected with anti-static stickers. If an automated machine inspection device is used, after the OGC appearance inspection is completed, additional manual labor is required to apply the anti-static stickers. This not only increases the production process and labor costs, but may also cause secondary damage to the OGC appearance due to the secondary operation, affecting the product qualification rate.

[0005] Therefore, for such special models of in-vehicle OGC products, the industry currently mostly adopts manual visual inspection. That is, while completing the appearance inspection at the inspection station, the anti-static sticker is simultaneously applied to reduce process redundancy. However, since the in-vehicle rear electric folding ceiling screen is an automotive-grade device and is equipped with a metal hinge assembly, its overall weight is much greater than that of conventional consumer electronics displays. During the operation, inspectors need to frequently lift the product and rotate it in multiple directions to complete a comprehensive inspection. The labor intensity is much higher than that of conventional inspection operations, and long-term operation can easily lead to personnel fatigue. Summary of the Invention

[0006] The purpose of this invention is to provide an OGC multi-directional rotary appearance inspection device to overcome the shortcomings of the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an OGC multi-directional rotary appearance inspection device, comprising:

[0008] The workbench has a rotating base rotatably connected to its top.

[0009] The inspection platform, hinged to a rotating base, is used to hold an electric folding ceiling screen.

[0010] Clamping components are symmetrically arranged on both sides of the inspection platform;

[0011] The power unit is used to drive the clamping assembly to clamp and fix the rotating shaft assembly of the electric folding ceiling screen. After clamping, it continues to drive the inspection platform to tilt around the hinge so that the screen faces the inspection personnel.

[0012] The ribbon cable warping component, connected to the power unit, can lift the ribbon cable of the electric folding ceiling screen to allow for the application of an anti-static protective film.

[0013] Preferably, the bottom of the inspection platform is fixedly provided with a hinge assembly, the bottom end of which is fixedly assembled with the rotating base to realize the hinged engagement between the inspection platform and the rotating base.

[0014] Preferably, the clamping assembly includes a sliding block, a three-headed pressure plate, and a tension spring; the sliding block is slidably connected to the inspection platform, the three-headed pressure plate is fixed to the top of the sliding block, and the tension spring provides a tensioning force to the sliding block toward the rotating shaft assembly, so that the clamping assembly has an automatic clamping tendency.

[0015] Preferably, the power unit includes a lead screw, a servo motor, an expansion arm, and a guide block. The middle part of the lead screw is rotatably mounted on a hinge assembly.

The guide block is fixedly installed on a rotating base.

[0016] Preferably, the outer wall of the lead screw is machined with two sections of threads with opposite directions, which are used to drive a pair of expansion arms to move synchronously in opposite directions.

[0017] Preferably, when the pair of expansion arms are extended in opposite directions, the clamping assembly is in a loose clamping state; when the pair of expansion arms are brought closer together, the clamping assembly is in a locked clamping state.

[0018] Preferably, the expansion arm is equipped with a roller. In the clamping state, the pair of expansion arms continuously move towards each other, and the roller and the guide block squeeze together, so that the push inspection platform can tilt and flip.

[0019] Preferably, the cable warping assembly includes a lower connecting block, an upper moving plate, a warping component, a lower pad, and an extrusion strip. The lower connecting block is threaded onto the end of the lead screw, and the upper moving plate is slidably connected to the inspection platform, with its bottom fixedly connected to the lower connecting block.

[0020] Preferably, the warping component is detachably mounted on the top of the upper movable plate for warping the wiring, the lower pad is fixed to the bottom of the upper movable plate, and the extrusion strip is fixedly installed on the inspection platform and located on the moving path of the upper movable plate.

[0021] Preferably, the rotating base can rotate 360 ​​degrees horizontally relative to the worktable, and in conjunction with the tilting action of the inspection platform, it enables multi-directional appearance inspection of the electric folding ceiling screen.

[0022] In the above technical solution, the present invention provides an OGC multi-directional rotary appearance inspection device, which solves the problem of high labor intensity during manual inspection of heavy automotive-grade ceiling screens through a power-linked rotary clamping structure. Furthermore, by adopting a synchronous linkage design for detection and cable warping, the OGC appearance inspection and anti-static sticker pasting process are integrated, avoiding secondary operations that could damage the product and eliminating process redundancy.

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Please see Figure 1-7 The present invention provides an OGC multi-directional rotary appearance inspection device, comprising:

[0034] Workbench 1, with a rotating base 2 rotatably connected to its top;

[0035] Inspection platform 3 is hinged to rotating base 2 and used to place electric folding ceiling screen 7;

[0036] Clamping components 4 are symmetrically arranged on both sides of the inspection platform 3;

[0037] The power unit 5 is used to drive the clamping assembly 4 to clamp and fix the rotating shaft assembly of the electric folding ceiling screen 7. After clamping, it continues to drive the inspection platform 3 to tilt around the hinge so that the screen faces the inspection personnel.

[0038] The ribbon cable warping component 6 is connected to the power unit 5 and can lift the ribbon cable of the electric folding ceiling screen 7 to allow for the application of an anti-static protective film.

[0039] In this embodiment, the rotating base 2 can rotate horizontally on the top of the workbench 1, and the inspection platform 3 can tilt around the hinge point to adjust the angle of the product. Through the combination of the two, multi-directional adjustment of the product can be achieved, and the inspection can be carried out without blind spots.

[0040] By using the simultaneous action of the clamping components 4 on both sides, the pivot assembly of the electric folding ceiling screen 7 can be positioned and clamped, which can securely fix the product on the inspection platform 3 and prevent the product from shaking or shifting during inspection.

[0041] The power unit 5 drives the clamping assembly 4 to clamp the fixed rotating shaft assembly. After clamping, it drives the inspection platform 3 to tilt so that the screen faces the inspector. The power unit 5 drives the relevant components in sequence according to the order of clamping first and then tilting, ensuring product stability and eliminating the need for manual lifting of heavy vehicle-mounted ceiling screens, greatly reducing the labor intensity of inspectors.

[0042] The ribbon cable warping component 6 is connected to the power unit 5 for transmission, which can lift the ribbon cable to apply the anti-static protective film, so that the detection and ribbon cable warping can be completed at the same station, reducing the secondary film application process and avoiding secondary damage to the product;

[0043] In another embodiment of the present invention, a hinge assembly 8 is fixedly provided at the bottom of the inspection platform 3, and the bottom end of the hinge assembly 8 is fixedly assembled with the rotating base 2 to realize the hinged engagement between the inspection platform 3 and the rotating base 2. Specifically, the hinge assembly 8 serves as a base point to ensure the tilting and rotation of the inspection platform 3.

[0044] In an embodiment of the present invention, the clamping assembly 4 includes a sliding block 41, a three-headed pressure plate 42, and a tension spring 43. The sliding block 41 is slidably connected to the inspection platform 3, the three-headed pressure plate 42 is fixedly connected to the top of the sliding block 41, and the tension spring 43 provides a tensioning force to the sliding block 41 toward the rotating shaft assembly, enabling the clamping assembly 4 to have an automatic clamping tendency. The power unit 5 includes a lead screw 51, a servo motor 52, an expansion arm 53, and a guide wedge 55. The middle part of the lead screw 51 is rotatably mounted on the hinge assembly 8, and a pair of expansion arms 53 are threaded onto the outside of the lead screw 51, with both ends extending into the movement path range of the sliding block 41. The guide wedge 55 is fixedly installed on the rotating base 2. The outer wall of the lead screw 51 is machined with two sections of threads with opposite directions, used to drive the pair of expansion arms 53 to move synchronously toward or away from each other. When the pair of expansion arms 53 are extended in opposite directions, the clamping assembly 4 is in a loose clamping state; when the pair of expansion arms 53 are close to each other, the clamping assembly 4 is in a locked clamping state.

[0045] Specifically, in the initial state of the device, the servo motor 52 of the power unit 5 is not started, the lead screw 51 remains stationary, and the pair of expansion arms 53 are in the extreme positions of opposite expansion (as shown in the attached figure). Figure 2 As shown), at this time, the expansion arm 53 forms abutment restriction on the sliding block 41 of the clamping component 4, and the tensioning force of the tension spring 43 cannot push the sliding block 41 to move. The clamping component 4 is in a loose clamping state. At this time, the inspection platform 3 remains horizontal, which makes it easy for the inspectors to place the electric folding ceiling screen 7 on the inspection platform 3 to complete the product loading operation.

[0046] After the material is loaded, the servo motor 52 is started to drive the lead screw 51 to rotate. Because the outer wall of the lead screw 51 is machined with two sections of threads with opposite directions, a pair of expansion arms 53 move synchronously towards each other under the action of thread transmission, gradually releasing the abutment restriction on the sliding block 41 of the clamping component 4. Under the tension and pushing force of the tension spring 43, the sliding block 41 slides towards the rotating shaft component of the electric folding ceiling screen 7, driving the top three-head pressure plate 42 to move synchronously until the three-head pressure plate 42 is tightly fitted with the rotating shaft component, realizing the locking and clamping of the product. This clamping method relies on the elastic force of the tension spring 43 and the transmission limit of the expansion arm 53, which not only ensures the firmness of the clamping and adapts to the fixing requirements of the metal rotating shaft component, but also avoids the structural damage to the product caused by rigid clamping. It solves the problem of having to hold heavy products during manual inspection and reduces labor intensity from the source.

[0047] In another embodiment of the present invention, a roller 54 is installed on the expansion arm 53. In the clamping state, the pair of expansion arms 53 continuously move towards each other, and the roller 54 and the guide inclined block 55 are pressed together, pushing the inspection platform 3 to achieve tilting and flipping. Specifically, after the clamping assembly 4 completes the clamping, the expansion arms 53 continue to move towards each other under the transmission of the lead screw 51. The roller 54 at its end gradually contacts the guide inclined block 55 on the rotating base 2 and produces a pressing engagement. The inclined structure of the guide inclined block 55 converts the horizontal displacement of the expansion arm 53 into an upward pushing force, pushing the inspection platform 3 to tilt upward around the hinge of the hinge assembly 8 and the rotating base 2 until the screen faces the inspector at a suitable angle. This design realizes the linkage between clamping and tilting actions, without the need for an additional power source to control the angle adjustment of the inspection platform 3, simplifying the operation process of the equipment. At the same time, the tilting angle is adapted to the visual needs of human eye observation, improving the convenience of appearance inspection. Compared with manual product handling, the mechanical tilting angle is more stable and can effectively ensure the comprehensiveness of the inspection.

[0048] Furthermore, clamping and platform tilting are achieved through a single lead screw 51, which simplifies the power structure and synchronizes the processes. In actual use, this structure can only trigger the tilting and flipping of the inspection platform 3 after the expansion arms 53 move in opposite directions to complete the product clamping and locking. This completely eliminates human error such as product falling and damage due to flipping before clamping or accidental flipping when the clamp is loose. It achieves full-process operational error tolerance without the need for a foolproof mechanism, significantly reducing the risk of product scrap and equipment safety hazards.

[0049] In another embodiment of the present invention, the cable warping assembly 6 includes a lower connecting block 61, an upper moving plate 62, a warping element 63, a lower pad 64, and an extrusion strip 65. The lower connecting block 61 is threaded onto the end of the lead screw 51. The upper moving plate 62 is slidably connected to the inspection platform 3, and its bottom is fixedly connected to the lower connecting block 61. The warping element 63 is detachably mounted on the top of the upper moving plate 62 for warping the cable. The lower pad 64 is fixed to the bottom of the upper moving plate 62. The extrusion strip 65 is fixedly installed on the inspection platform 3 and located on the moving path of the upper moving plate 62.

[0050] Specifically, during the rotation of the lead screw 51, in the initial stage, the upper moving plate 62 of the cable warping assembly 6 is also in its initial position due to the threaded engagement between the lower connecting block 61 and the lead screw 51. The warping element 63 does not act on the cable. As the rotation continues, while the lead screw 51 continuously drives the expansion arm 53 to move, the threaded transmission at its end drives the lower connecting block 61 to move synchronously. The lower connecting block 61 is fixed to the upper moving plate 62, thereby pulling the upper moving plate 62 to slide on the inspection platform 3. The warping element 63 at the top of the upper moving plate 62 moves along with it, gradually extending under the cable of the electric folding ceiling screen 7. Continuing to move, the lower pad 64 at the bottom of the upper moving plate 62 cooperates with the extrusion strip 65 on the inspection platform 3 during the movement, so that the warped part 63 is tilted upwards, thereby slowly tilting the ribbon cable to facilitate the worker to apply film to the gold fingers of the ribbon cable. This design allows the ribbon cable to be warped, clamped, and tilted simultaneously, integrating the appearance inspection and anti-static film application process into the same workflow. This solves the problem of secondary operation required for existing machine inspection, eliminates process redundancy, reduces labor costs, and avoids secondary damage such as scratches and dirt to the OGC surface caused by secondary operation, effectively improving the product qualification rate.

[0051] In this embodiment of the invention, the rotating base 2 can rotate 360 ​​degrees horizontally relative to the worktable 1. Combined with the tilting action of the inspection platform 3, this enables multi-directional appearance inspection of the electric folding ceiling screen 7. Because the rotating base 2 can rotate 360 ​​degrees horizontally relative to the worktable 1, inspectors can rotate the rotating base 2 according to inspection needs, causing the clamped and fixed electric folding ceiling screen 7 to rotate horizontally in a circular motion. Combined with the adjustable tilt angle of the inspection platform 3, this allows for comprehensive appearance inspection of the product from all angles and directions, eliminating blind spots. Compared to manually rotating the product by hand, mechanical rotation offers higher stability.

[0052] Optionally, the rotation of the rotating base 2 can be electrically assisted. In this way, in conjunction with the servo motor 52, it can achieve fixed-angle positioning and uniform rotation. All inspectors can complete the full inspection under the same observation angle and lighting conditions, reducing variables in the inspection process.

[0053] After inspection and film application are completed, the servo motor 52 is started in reverse, driving the lead screw 51 to rotate in the opposite direction. A pair of expansion arms 53 move synchronously in opposite directions under the threaded transmission. First, the squeezing fit with the guide block 55 is released, and the inspection platform 3 returns to a horizontal state under its own gravity. Then, the expansion arms 53 continue to move in opposite directions and abut against the sliding block 41 of the clamping component 4 again, pushing the sliding block 41 to move outward against the force of the tension spring 43, thereby releasing the clamping component 4. At the same time, the reverse rotation of the lead screw 51 drives the upper moving plate 62 of the cable warping component 6 to reset, and the warping component 63 releases its warping effect on the cable. The inspector can directly remove the finished product, completing the entire operation process. The linkage design of the reverse action allows the equipment to reset and release simultaneously, simplifying the unloading operation. The entire operation process only requires manual completion of loading, inspection and judgment, application of antistatic film and unloading operations. All other actions are completed mechanically by the equipment, greatly reducing the labor intensity of workers.

[0054] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
