Description

Technical Field

[0001] This utility model relates to the field of mobile phone manufacturing equipment technology, specifically a film-peeling platform mechanism for the reverse folding process of mobile phone display module FPC. Background Technology

[0002] In the production process of mobile phone display modules, the film-peeling step before the FPC (Flexible Printed Circuit Board) reversal process is crucial. Existing film-peeling equipment has many problems (it cannot peel the film at multiple angles), which greatly affects production efficiency and product quality. In terms of positioning accuracy, existing film-peeling platforms have limited precision in X and Y direction movement and angle adjustment, making it difficult to accurately position the film edge of the FPC. This leads to incomplete film tearing, residue, or damage to the FPC during the peeling process. In terms of adsorption and clamping, the adsorption force is uneven and cannot firmly fix the FPC. The FPC is prone to displacement during peeling, affecting the peeling effect. Moreover, the clamping device often cannot be flexibly adjusted according to the different thicknesses and materials of the FPC, resulting in poor applicability. In addition, existing equipment has a low degree of automation, is complex to operate, and requires frequent manual intervention, increasing labor costs and failing to meet the needs of large-scale, high-efficiency modern production. Therefore, this utility model proposes a film-peeling platform mechanism for the FPC reversal process of mobile phone display modules. Utility Model Content

[0025] 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.

[0026] Please see Figures 1-4 As shown, this utility model provides a technical solution: a film-tearing platform mechanism for the reverse folding process of mobile phone display module FPC, including a Y-axis moving device 1, an R-axis rotating device 2, a product adsorption platform 3 for carrying the mobile phone display module, and an FPC adsorption and pressing device 4 for fixing the FPC.

[0027] The Y-axis moving device 1 includes a servo motor 101 and a lead screw module 102. The servo motor 101 drives the lead screw module 102, which in turn drives the product adsorption platform 3 to move linearly. The lead screw module 102 includes a housing 1021, and a rotatable lead screw 1022 is installed inside the housing 1021. The output end of the servo motor 101 is connected to the lead screw 1022. The Y-axis moving device enables the platform to move precisely in the Y-axis direction with an accuracy of ±0.01mm, ensuring that it can be accurately positioned at the edge of the FPC film.

[0028] The R-axis rotation device 2 includes a second servo motor 201 and a rotating platform 202. The second servo motor 201 drives the rotating platform 202 to rotate. A reducer 203 is installed at the output end of the second servo motor 201. The reducer 203 is fixedly installed on the platform support 301, and the rotating platform 202 is fixed at the output end of the reducer 203. An adsorption hole 2021 is opened on the rotating platform 202, and a vacuum adsorption head 401 is installed below the adsorption hole. The R-axis rotation device provides precise angle adjustment with an accuracy of ±0.02° to meet the needs of film tearing at different angles.

[0029] The product adsorption platform 3 includes a platform bracket 301, which is slidably mounted on the lead screw module 102. The platform bracket 301 has a threaded hole 302 that is threadedly connected to the lead screw 1022. The rotation of the lead screw 1022 drives the platform bracket 301 to move linearly.

[0030] The FPC adsorption and pressing device 4 includes a vacuum adsorption head 401 installed at the bottom of the rotating platform 202. The vacuum adsorption head 401 is connected to a vacuum generator through a pipe. The FPC adsorption and pressing device 4 also includes a fixing frame 402 fixed on one side of the rotating platform 202. A cylinder 403 is installed on the fixing frame 402. The output end of the cylinder 403 is connected to a pressure rod 404. The pressure rod 404 is located above the rotating platform 202 and uses vacuum adsorption force to fix the FPC. The adjustable pressing component can adapt to FPCs of different thicknesses and materials to ensure that the FPC does not shift during the film peeling process.

[0031] Working Principle: Before peeling off the film, the mobile phone display module is placed on the product adsorption platform, which then activates its adsorption function to fix the display module in place. Next, based on the position of the FPC film, the servo motor of the Y-axis moving device drives the lead screw module to precisely move the platform to the film peeling starting position. If angle adjustment is required, the servo motor of the R-axis rotating device drives the rotating platform to adjust the FPC to the appropriate angle. Then, the vacuum adsorption of the FPC adsorption and pressing device is activated, tightly adsorbing the FPC, while the pressing component adjusts the pressing force according to the thickness and material of the FPC. After completing the preparation work, the film peeling operation is performed. During the film peeling process, all devices work together to ensure smooth peeling.

[0032] Installation and debugging before use: Install the film-peeling platform mechanism at the designated location on the mobile phone display module production line, ensuring it is securely installed and level. Connect the electrical and pneumatic circuits of the servo motors, vacuum adsorption devices, etc., and set the parameters of the Y-axis and R-axis servo motors, such as setting the movement speed, rotation speed, and angle range. Adjust the adsorption force and clamping force of the FPC adsorption and clamping devices according to the thickness and material of common FPCs.

[0033] The operating procedure for this equipment is as follows: Place the mobile phone display module on the product adsorption platform and activate the adsorption function to fix the module. Based on the position of the FPC film, the control system sends a command to the Y-axis moving device. The servo motor drives the lead screw module, moving the platform to the film-tearing starting position. If angle adjustment is required, the control system controls the R-axis rotation device, and the servo motor drives the rotating platform to rotate to the appropriate angle. Next, the FPC adsorption and pressing device is activated, vacuum adsorbing the FPC while the pressing component adjusts the pressing force. Once everything is ready, the film is peeled off using the automated film-tearing device.

[0034] Maintenance and Alternative Solutions for this Equipment: Regularly check the sealing and adsorption force of the vacuum adsorption device. If any problems are found, replace the seals or maintain the vacuum vents promptly. Check the operating status of the servo motor, lead screw module, and rotary platform, perform lubrication and maintenance, and replace worn parts in a timely manner. Regarding alternative solutions, the lead screw module can be replaced with a linear guide structure driven by a linear motor to improve movement speed and accuracy. For the rotary platform, products from different brands with similar precision and performance can be selected. For the FPC adsorption and clamping device, other new adsorption materials can be used to improve the adsorption effect, and the clamping assembly can be designed with a more intelligent automatic adjustment structure to automatically adjust the clamping force according to the FPC parameters.
