[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the invention and do not constitute a limitation thereof.

[0034] Please see Figure 1-2 This specific embodiment provides an automated curved surface adhesive application device, including a machine base 1, a turntable 2, a workpiece feeding module 3, an adhesive film application module 4, a re-inspection module 5, and a material unloading module 6;

[0035] Among them, the upper surface of machine base 1 is a horizontal plane, and the upper surface of machine base 1 provides ample installation space for other components. Other components use machine base 1 as the installation base and structural support.

[0036] Turntable 2 is set on machine base 1. Specifically, turntable 2 is set in the center of machine base 1, protruding from the upper surface of machine base 1, and turntable 2 is rotatably connected to machine base 1. Turntable 2 can rotate around the vertical direction.

[0037] The workpiece feeding module 3 is set on the machine base 1 and is located on one side of the turntable 2. The workpiece feeding module 3 is close to the turntable 2 and moves the curved workpiece to the turntable 2.

[0038] Film mounting module 4 is set on machine base 1 and film mounting module 4 is set on one side of turntable 2. Film mounting module 4 is close to turntable 2. Film mounting module 4 moves film to turntable 2 and attaches it to curved workpiece.

[0039] The unloading module 6 is set on the machine base 1 and is located on one side of the turntable 2. The unloading module 6 is close to the turntable 2 and removes the curved workpiece that has been attached with the film from the turntable 2.

[0040] And a re-inspection module 5, which is set on the machine base 1 and on one side of the turntable 2. The re-inspection module 5 is set between the film mounting module 4 and the unloading module 6. The re-inspection module 5 faces the turntable 2 to check the film bonding of the curved workpiece on the fixture 23.

[0041] The turntable 2 is positioned in the center of the machine base 1. The workpiece loading module 3, film mounting module 4, re-inspection module 5, and unloading module 6 surround the turntable 2. As the turntable 2 rotates once on the machine base 1, it sequentially passes through the loading station of the workpiece loading module 3, the mounting station of the film mounting module 4, the verification station of the re-inspection module 5, and the unloading station of the unloading module 6. The design of the turntable 2 allows workpieces to flow orderly between different stations. Each module performs its specific function, working together to complete the entire process from workpiece loading, film mounting, quality re-inspection to finished product unloading. This layout not only improves production efficiency but also ensures the accuracy and quality of adhesive application, effectively solving the problem that existing automated mounting equipment is difficult to directly apply to curved workpieces, thus meeting the adhesive application needs of curved workpieces in electronic products.

[0042] Please see Figure 3 In this specific embodiment, the turntable 2 includes a turntable driver 21, a turntable body 22, and at least one fixture 23. The body of the turntable driver 21 is mounted on the machine base 1, the drive output shaft of the turntable driver 21 is connected to the turntable body 22, and the fixture 23 is fixedly mounted on the turntable body 22. It should be noted that the structure and working principle of the turntable driver 21 itself are not the core content of this application. In specific implementations, technicians can choose servo motors, servo motors, or other devices that provide driving force as needed as the turntable driver 21 to implement this solution.

[0043] In another specific embodiment, four fixtures 23 are provided, all arranged on concentric circles centered on the center of the disk body 22, and the four fixtures 23 are evenly spaced. As described above, in the automated curved surface adhesive application device provided in this specific embodiment, four modules are arranged sequentially around the turntable 2: a workpiece loading module 3, a film application module 4, a re-inspection module 5, and a unloading module 6. With the center of the disk body 22 as the center, the above four modules are arranged in a counterclockwise direction around the disk body 22, so that the workpiece loading module 3, film application module 4, re-inspection module 5, and unloading module 6 form a "cross" shape around the disk body 22. In this way, four fixtures 23 are set up corresponding to the four modules mentioned above: workpiece loading module 3, film mounting module 4, re-inspection module 5, and unloading module 6. The four fixtures 23 are evenly spaced and set on concentric circles with the center of the disk body 22 as the center. By controlling the specific rotation angle and start / stop position of the turntable driver 21, when the disk body 22 is stationary, the four fixtures 23 are aligned with the four modules respectively, with the first fixture 23 aligned with the loading station of the workpiece loading module 3. The first jig, 23, can work with the second jig, 23, to independently complete the loading process of a single curved workpiece to be processed. The second jig, 23, is aligned with the mounting station of the film mounting module, 4, which can work with the jig, 23 to independently complete the mounting process of a single curved workpiece to be mounted. The third jig, 23, is aligned with the verification station of the re-inspection module, 5, which can work with the jig, 23 to independently complete the verification process of a single curved workpiece with mounted film. The fourth jig, 23, is aligned with the unloading station of the unloading module, 6, which can work with the jig, 23 to complete the unloading process of a single curved workpiece that has passed verification. Setting up four jigs, 23, allows the above four processes to be performed relatively independently and simultaneously. After the current process is completed, the turntable driver, 21, only needs to drive the turntable body, 22, to rotate 90° counterclockwise to transport the curved workpiece that has completed the previous process to the next process segment. The control process is easy to operate and implement, and the production efficiency is significantly improved.

[0044] Please see Figure 1-3In this specific embodiment, eight fixtures 23 are provided, all arranged on concentric circles centered on the center of the disk body 22, and the eight fixtures 23 are evenly spaced. As mentioned above, the workpiece loading module 3, film mounting module 4, re-inspection module 5, and unloading module 6 are arranged in a "cross" shape around the turntable 2. Eight fixtures 23 are provided corresponding to the above four modules. By maintaining the eight fixtures 23 evenly spaced and arranged on concentric circles centered on the center of the disk body 22, the specific rotation angle and start / stop position of the turntable driver 21 can be controlled so that when the disk body 22 is stationary, the first fixture 23 aligns with the loading station of the workpiece loading module 3, the third fixture 23 aligns with the mounting station of the film mounting module 4, and the fifth fixture 23 aligns with the re-inspection module 5. When the seventh fixture 23 aligns with the unloading station of the unloading module 6, the second, fourth, sixth, and eighth fixtures 23 remain silent and wait. The workpiece loading module 3, film mounting module 4, re-inspection module 5, and unloading module 6 each perform their respective functions, cooperating with their corresponding fixtures 23 to complete their respective processing steps. Then, the turntable driver 21 drives the turntable body 22 to rotate 45° counterclockwise. The second, fourth, sixth, and eighth fixtures 23 will then enter the processing segment and align with their corresponding modules. In this way, the setup of eight fixtures 23 will significantly shorten the cycle time, improve cycle efficiency, and increase processing efficiency.

[0045] Please see Figure 2-4 In this specific embodiment, the workpiece loading module 3 includes a material tray 31, a workpiece loading groove 32, and a workpiece loading hand 33. The material tray 31 has an internal accommodating space where the curved workpiece to be processed is temporarily stored. The workpiece loading groove 32 is laid between the material tray 31 and the tray body 22, with its first end connected to the material tray 31 and its last end connected to the tray body 22. The workpiece loading hand 33 is located near the end of the workpiece loading groove 32. The workpiece loading hand 33 picks up the curved workpiece to be processed from the workpiece loading groove 32 and transfers it to the nearest fixture 23. With a reasonable workpiece loading hand 33 structure, such as using a negative pressure suction nozzle with controllable adsorption capacity as the workpiece loading robot, it can be applied to curved workpieces in electronic products with arc-shaped, curved, or other non-standard irregular shapes. Considering their small size, light weight, and non-planar surface to be mounted, it can accurately pick up the curved workpiece and transfer it to the corresponding fixture 23.

[0046] Please see Figure 2-5In this specific embodiment, the film mounting module 4 includes a film feeder 41, a film transfer frame 42, and a film mounting hand 43. The film feeder 41 has a film roll storage space inside, where film rolls are temporarily stored. The film transfer frame 42 spans between the film feeder 41 and the tray 31. The film mounting hand 43 is disposed on the film transfer frame 42 and is movably connected to the film transfer frame 42. The film transfer frame 42 pushes the film mounting hand 43 to reciprocate between the film feeder 41 and the tray 31. The film mounting hand 43 includes a telescopic actuator 431 and a mounting head 432. The body of the telescopic actuator 431 is connected to the film transfer frame 42, and the output shaft of the telescopic actuator 431 is connected to the mounting head 432. The output shaft of the telescopic actuator 431 can... Extending or shortening vertically, the film transfer frame 42 pushes the telescopic actuator 431 to move above the film feeder 41. At this time, the output shaft of the telescopic actuator 431 extends, driving the placement head 432 to approach the film feeder 41. The placement head 432 picks up the film to be placed from the film feeder 41. After the placement head 432 picks up the film to be placed, the output shaft of the telescopic actuator 431 retracts. At this time, the film transfer frame 42 pushes the telescopic actuator 431 to move above the turntable 2 and hovers above one of the fixtures 23. At this time, the output shaft of the telescopic actuator 431 extends again, pressing the film onto the surface of the curved workpiece fixed on the fixture 23. Thus, the film placement hand 43 completes the entire process of picking up the film to be placed from the film feeder 41 and placing it onto the surface of the curved workpiece.

[0047] Please see Figure 2-5 In this specific embodiment, the re-inspection module 5 includes a re-inspection camera 51. The re-inspection camera 51 faces the turntable 2 to capture a real-time image of the curved workpiece on the nearest fixture 23. The real-time image is analyzed to identify objects in the image and calculate the outline shape and size of the curved workpiece captured in the image. If the outline shape of the curved workpiece is abnormal or its size has changed significantly compared to before multiple mountings, it can be determined that there is an error in the current mounting process, such as the double-sided adhesive being misaligned or failing to fully adhere to the surface of the curved workpiece to be mounted. In this case, the curved workpiece is a defective product and needs to be inspected and discarded separately. Setting up the re-inspection module 5 allows for timely and effective inspection of the current automated curved surface mounting effect, helping to further improve the accuracy of automated adhesive application to curved workpieces.

[0048] Please see Figure 2-5In this specific embodiment, the unloading module 6 includes a tape unwinding shaft 61, a tape rewinding shaft 62, and an unloading robot 63. The tape unwinding shaft 61 and the tape rewinding shaft 62 are spaced apart, and the unloading robot 64 is tensioned and wound between the tape unwinding shaft 61 and the tape rewinding shaft 62. The unloading robot 63 is located on one side of the turntable 2. The unloading robot 63 picks up the curved workpiece with film attached from the turntable 2 and transfers it to the unloading robot 64 for tape unloading. The tape unwinding shaft 61 and the tape rewinding shaft 62 provide continuous traction force for the unloading robot 64, enabling it to continuously and stably flatten and pass through, providing reliable material support for the unloading process. The unloading robot 63, with its high-precision gripping and transfer capabilities, accurately picks up the curved workpiece with film attached from the turntable 2 and places it stably on the unloading robot 64 for tape unloading. During this process, the unloading robot 63 moves in a coordinated and rapid manner, ensuring the efficiency and accuracy of the entire unloading process. In addition, the unloading module 6 can be flexibly adjusted according to actual production needs, such as changing to different specifications of material strips or adjusting the gripping force of the unloading robot 63, to adapt to the unloading needs of curved workpieces of different sizes and shapes.
