Abstract
Description
Technical Field
[0001] This utility model relates to the field of alignment and bonding technology, specifically to a bonding and alignment mechanism that can be used for dual 3D displays. Background Technology
[0002] In the automotive LCD display industry, a series of equipment are deployed for pre-processing and post-processing steps, such as evaporation, photolithography, printing, testing, bonding, and encapsulation. The bonding process uses adhesive materials to seamlessly bond glass covers, display panels, and touch sensors together. Alignment bonding involves aligning the marks on the two parts to be bonded and then applying pressure to bond them. Traditionally, manual operation involves production line workers visually comparing and bonding the two parts together, while other workers verify the bonding accuracy. With the development of technology, higher demands are placed on the precision and speed of bonding for automotive LCD displays. Whether using manual bonding or tooling, it is difficult to overcome the problems of insufficient precision and efficiency.
[0003] Traditional alignment and bonding technology is relatively mature. Commonly used bonding and alignment methods include 2-camera to 2-camera and 4-camera to 4-camera bonding. By using the mark points on the product (such as cross marks, round hole marks, etc.) as identification points, the position of the upper and lower products can be determined, which can meet the bonding tasks of various sizes of vehicle display screens.
[0004] However, nowadays, in-vehicle displays are no longer limited to the square shape. Chinese patent document CN201711418889.5 provides a "Method for Laying and Aligning Irregularly Shaped Materials", which includes: a method for laminating and aligning irregularly shaped materials. This method addresses the problem that existing laminating materials have become irregularly shaped, and that there is a problem of misalignment during the lamination process. Therefore, it uses the original irregular shape of the laminating material to define a straight line associated with the tangent of the shape as the shape alignment feature of the laminating material. It can also provide a definition of the alignment relationship between the laminating material and the object being laminated, thereby controlling the lamination tolerance and preventing the laminating material from exceeding the object being laminated, thus meeting consumers' needs for product appearance.
[0005] However, this technical solution still has shortcomings. It can only be used for flat displays with curved edges, and it has limitations in recognizing 3D curved products. Furthermore, this technology does not provide a means to detect whether the recognition is correct, and subsequent accuracy verification requires additional labor costs. Therefore, there is an urgent need to design a bonding and alignment mechanism applicable to various new types of automotive displays. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 This embodiment provides the following technical solution:
[0024] A bonding and alignment mechanism for dual 3D displays includes an optical platform 1, a linear slide 2 fixedly mounted on the upper end of the optical platform 1, a positioning structure 3 mounted on the upper end of the linear slide 2, a pressing structure 4 mounted above the positioning structure 3, and a support frame 5 mounted above the pressing structure 4. The pressing structure 4 includes a sealing cover 403, which is fixedly connected to the support frame 5 via a guide rod. A panel adsorption and separation structure 402 is provided inside the sealing cover 403, and a panel body 401 is adsorbed onto the suction cup of the panel adsorption and separation structure 402. The positioning structure 3 includes a carrier plate 301, and a back shell adapted to the panel body 401 is mounted on the upper end of the carrier plate 301. The linear slide 2 is used to adjust the lateral horizontal movement of the positioning structure 3, and the positioning structure 3 is used to position the back shell. The positioning structure 3 is also provided with a fine-tuning structure to ensure consistent alignment when the two panels are bonded. The support frame 5 drives the pressing structure 4 to lift and rotate via a lifting and rotating mechanism.
[0025] In this embodiment, a first positioning clamping structure 305 and a second positioning clamping structure 306 are respectively provided on the support plate 301. The first positioning clamping structure 305 includes two positioning sliders, and the distance between the two positioning sliders is adjusted by a bidirectional lead screw 308 driven by a motor.
[0026] The second positioning and clamping structure 306 includes two positioning sliders. A drive rod 302 is rotatably mounted on the top inner wall of the support plate 301. An electric push rod 304 is mounted on one side of the drive rod 302. The two ends of the drive rod 302 are respectively connected to the positioning sliders via connecting rods 303. By driving the electric push rod 304 to extend and retract, the drive rod 302 is rotated. Under the transmission of the connecting rod 303, the distance between the two positioning sliders is adjusted.
[0027] In this embodiment, a fixed sleeve 311 is provided inside one of the positioning sliders of the first positioning clamping structure 305 and the second positioning clamping structure 306. A micrometer screw 310 is provided inside the fixed sleeve 311. A micrometer cylinder 312 is connected to the outer side wall of the fixed sleeve 311. Fixed graduations are engraved on the fixed sleeve 311, and movable graduations are engraved on the micrometer cylinder 312. A measuring felt is provided on the opposite side of the micrometer screw 310, and the measuring felt is located on the positioning slider. When the pressing structure 4 presses the panel body... After 401 is attached to the back shell, the double panel is finely adjusted through the fine-tuning structure to bring the measuring felt close to the panel. Then, by rotating the micrometer cylinder 312, the micrometer cylinder 312 will move forward along the threaded groove. The micrometer screw 310 located in the fixed sleeve 311 is connected to the bearing, and the bearing is fixed to the inner wall of the micrometer cylinder 312. Therefore, the micrometer screw 310 will not rotate, but will move forward with the movement of the micrometer cylinder 312 to measure the panel and ensure alignment accuracy.
[0028] In this embodiment, both the micrometer screw 310 and the measuring felt have mounting grooves for mounting U-shaped rubber heads 309. By mounting the rotatable and adjustable U-shaped rubber heads 309 and placing them close to the panel, the pitch angle of the panel can be changed to adapt to different working requirements or installation environments, thus improving the flexibility of the equipment. By precisely adjusting the pitch angle, the contact effect between the panel and other components can be optimized, reducing friction or gaps and improving the overall performance and service life of the product.
[0029] Working Principle: This utility model is designed for bonding a dual 3D display screen and its back shell. In use, the back shell is first placed on the support plate 301. Initial positioning of the back shell is achieved through the first positioning clamping structure 305 or the second positioning clamping structure 306. Then, the position of the positioning structure 3 is adjusted by the linear slide 2 so that the positioning structure 3 is directly below the pressing structure 4. Afterwards, the pressing structure 4 moves downward under the drive of the lifting and rotating mechanism, causing the panel body 401 to bond with the back shell. When the pressing structure 4... After the panel body 401 is attached to the back shell, the two panels are finely adjusted by the fine-tuning structure. The measuring felt is brought close to the panel. Then, by rotating the micrometer cylinder 312, the micrometer cylinder 312 will move forward along the thread groove. The micrometer screw 310 located in the fixed sleeve 311 is connected to the bearing, and the bearing is fixed to the inner wall of the micrometer cylinder 312. Therefore, the micrometer screw 310 will not rotate, but will move forward with the movement of the micrometer cylinder 312 to measure the panel and ensure alignment accuracy.
