[0002] Currently, many electronic products incorporate screens. Some screens are assembled from FOG (Flexible Printed Circuit) glass modules and BLU (Backlight Unit) backlight modules. FOG stands for FPC on glass, meaning a flexible printed circuit board (FPC) is bonded to glass. BLU stands for Backlight Unit, a light source component used in LCD displays. Screens on the market now come in various shapes, with circular screens becoming increasingly common. The semi-finished modules of circular screens can rotate around their central axis, potentially leading to misalignment during assembly. This presents significant challenges for automated bonding and assembly, and poor positioning can reduce work efficiency.

[0049] In this embodiment, both the FOG bonding camera and the BLU bonding camera 1C are dual cameras to provide bonding accuracy.

[0050] Please refer to Figure 2 and Figure 3In this embodiment, the FOG loading robot 13 includes a first movable seat 131, a lifting plate 132, an FOG lifting drive 133, a movable plate 134, an FOG movable drive 135, a rotating plate 136, an FOG rotating drive 137, and a suction cup assembly 138.

[0051] The lifting plate 132 is slidably connected to the first movable seat 131. The FOG lifting drive 133 is located on one side of the first movable seat 131, and its output end is connected to the lifting plate 132. The movable plate 134 is slidably connected to the lifting plate 132. The FOG movable drive 135 is located on the top of the lifting plate 132, and its output end is connected to the movable plate 134. A rotation drive is located on the top of the movable plate 134, and its output end is connected to the rotation plate 136. Multiple suction cup assemblies 138 are located on the rotation plate 136. After gripping the FOG glass module, the suction cup assemblies 138 can move and rotate to adjust their orientation.

[0052] The bottom of the lifting plate 132 is provided with a frame plate 1321, and a connecting plate 1311 is provided on one side of the first moving seat 131. The frame plate 1321 is slidably connected to one side of the first moving seat 131. The connecting plate 1311 passes through the frame plate 1321 and is connected to the FOG lifting drive component 133. The overall structure is compact.

[0053] A first limiting block 139 is provided on the top of one side of the first movable seat 131, and a second limiting block is provided on the bottom of the other side of the first movable seat 131.

The first limiting block 139 and the first lifting limiter 13A cooperate to limit the rising position of the lifting plate 132, and the second limiting block and the second lifting limiter cooperate to limit the falling position of the lifting plate 132.

[0054] Please refer to Figure 3 A fixed plate 13B1 is located below the moving plate 134. The fixed plate 13B1 is connected to the moving plate 134 via a connecting block 13B2. The fixed plate 13B1 is parallel to the moving plate 134. The output end of the rotation drive component passes through the fixed plate 13B1 and is connected to the rotating plate 136. The structure is stable, and the movement and rotation of the suction cup assembly 138 after gripping the FOG glass module are very stable. A rotation sensor 13C is provided on the rotating plate 136, and a rotation sensor 13D is provided on the fixed plate 13B1 corresponding to the rotation sensor 13C. A motion sensor 13F is provided on the lifting plate 132, and a motion sensor 13E is provided on the fixed plate 13B1 corresponding to the motion sensor 13F. The controller can accurately adjust the orientation of the FOG glass module based on the sensing signals of the rotation sensor 13D and the motion sensor 13F.

[0055] In this embodiment, the rotating plate 136 includes a first plate 1361 and a second plate 1362. The first plate 1361 is connected to the output end of the rotating drive component. Multiple suction cup assemblies 138 are disposed on the second plate 1362. The vertical side surfaces of the first plate 1361 and the second plate 1362 are in surface contact. For example, screws can be used to connect the first plate 1361 and the second plate 1362, achieving a detachable and fixed connection between the first plate 1361 and the second plate 1362. This allows for the quick replacement of multiple suction cup assemblies 138 by replacing the second plate 1362, enabling the rapid replacement of damaged suction cup assemblies 138, or facilitating the easy replacement with different suction cup assemblies 138 to accommodate FOG glass modules of different sizes.

[0056] Please refer to Figure 4 and Figure 5 In this embodiment, an FOG positioning component 121 is provided at one end of the FOG input line 12 near the FOG film tearing mechanism 14. The FOG positioning component 121 includes a moving positioning drive 1211, a first connecting rod 1212, a second connecting rod 1213, a positioning block 1214, and an anti-floating plate 1215.

[0057] The motion positioning drive 1211 is fixedly mounted on one side of the FOG input cable 12. One end of the first connecting rod 1212 is connected to the output end of the motion positioning drive 1211, and the other end of the first connecting rod 1212 is connected to the second connecting rod 1213. The second connecting rod 1213 has an elongated hole 12131, the first connecting rod 1212 has a first connecting hole, and the positioning block 1214 has a second connecting hole. A first screw passes through the elongated hole 12131 and connects to the first connecting hole, and a second screw passes through the elongated hole 12131 and connects to the second connecting hole. The extension position of the second connecting rod 1213 and the position of the positioning block 1214 relative to the FOG input cable 12 can be adjusted along the elongated hole 12131.

[0058] In this embodiment, two positioning blocks 1214 are disposed on the side of the second connecting rod 1213 away from the FOG film-tearing mechanism 14. The space between the two positioning blocks 1214 facilitates good positioning of the circular FOG glass module, making it difficult for the FOG glass module to move along the width direction of the FOG input line 12. An anti-floating plate 1215 is disposed on the top of the positioning block 1214 and extends out of the side of the positioning block 1214 away from the FOG film-tearing mechanism 14. The anti-floating plate 1215 can prevent the FOG glass module on the FOG input line 12 from shaking up and down, causing its position to shift.

[0059] When the FOG loading robot 13 grabs the FOG glass module on the FOG input line 12, the moving positioning drive 1211 will drive the positioning block 1214 to move away from the FOG glass module, and make the anti-floating plate 1215 avoid the FOG glass module.

[0060] Optionally, the sides of the two positioning blocks 1214 that are close to each other can be provided with inclined surfaces. The distance between the ends of the inclined surfaces of the two positioning blocks 1214 that are close to the FOG film-removing mechanism 14 is smaller than the distance between the ends that are far away from the FOG film-removing mechanism 14, so that a V-shaped positioning space for positioning the FOG glass module is formed between the two positioning blocks 1214, which can better position the FOG glass module.

[0061] Please refer to Figure 6 In this embodiment, the loading and unloading combined robot 16 includes a second movable seat 161, a lifting frame 162, a combined lifting drive 163, a first gripper 164, a BLU moving drive 165, a BLU rotating drive 166, a second gripper 167, and a screen rotating drive 168.

[0062] The lifting frame 162 is slidably connected to the second movable seat 161. The combined lifting drive 163 is located on one side of the second movable seat 161, and its output end is connected to the lifting frame 162. The BLU rotation drive 166 is horizontally slidably located at one end of the lifting frame 162, and the screen rotation drive 168 is fixedly located at the other end of the lifting frame 162. The output end of the BLU rotation drive 166 is connected to the first gripper 164, and the output end of the screen rotation drive 168 is connected to the second gripper 167. While the first gripper 164 picks up the BLU backlight module from the BLU input line 15 and transports it to the bonding platform 1E, the second gripper 167 picks up the bonded screen product from the bonding platform 1E and transports it to the output line 18. The operation is highly efficient, and the first gripper 164 can adjust the position of the BLU backlight module, while the second gripper 167 can adjust the position of the screen product.

[0063] Please refer to Figure 7In this embodiment, the FOG film-peeling mechanism 14 includes an FOG film-peeling fixing seat 141, a film-peeling platform 142, a film-peeling tape 143, and a tape take-up and release assembly 144. The film-peeling platform 142 is slidably connected to the FOG film-peeling fixing seat 141. The tape take-up and release assembly 144 is disposed on one side of the FOG film-peeling fixing seat 141. The film-peeling tape 143 is connected to the tape take-up and release assembly 144, and a section of tape 143 is flatly attached to the top surface of the film-peeling platform 142. The bonding robot 19 grasps the FOG glass module on the film-peeling platform 142. With the movement of the film-peeling platform 142, the tape 143 can gradually remove the film from the FOG glass module. After peeling, the FOG glass module grasped by the bonding robot 19 is photographed by the FOG bonding camera for subsequent positioning and bonding with the BLU backlight module.

[0064] Please refer to Figure 8 In this invention, the BLU film-tearing mechanism 17 includes a BLU film-tearing fixing seat 171, a film-tearing gripper 172, a film-tearing rotation drive 173, and a blower cleaning mechanism 174. The film-tearing rotation drive 173 is slidably connected to the BLU film-tearing fixing seat 171, and its output end is connected to the film-tearing gripper 172. The blower cleaning mechanism 174 is fixedly connected to the BLU film-tearing fixing seat 171 and is located above the film-tearing gripper 172. The film-tearing gripper 172 clamps one end of the film of the BLU backlight module, and the film can be peeled off by rotating the film-tearing gripper 172 in conjunction with the movement of the bonding platform 1E.

[0065] In this embodiment, the fully automatic circular backlight assembly machine also includes a defective product output line 1D, which is located on the side of the FOG film tearing mechanism 14 away from the FOG input line 12. Both the BLU film tearing mechanism 17 and the FOG film tearing mechanism 14 are equipped with film tearing sensors for detecting whether the film has been torn off. BLU backlight modules that fail to tear the film using the BLU film tearing mechanism 17 and FOG glass modules that fail to tear the film using the FOG film tearing mechanism 14 can be output by the defective product output line 1D.

[0066] The working principle of this invention is as follows: The BLU backlight module flows in from the BLU input line 15, and the FOG glass module flows in from the FOG input line 12. The controller, based on the image information captured by the FOG loading camera 1A, controls the FOG loading robot to grasp the FOG glass module on the FOG input line 12 and adjust its position, then places the FOG glass module onto the film-peeling platform 142. The controller, based on the image information captured by the BLU loading camera 1B, controls the first gripper 164 to grasp the BLU backlight module on the BLU input line 15 and adjust its position, then places the BLU backlight module onto the bonding platform 1E.

[0067] The bonding robot 19 grasps the FOG glass module on the film-peeling platform 142. With the movement of the film-peeling platform 142, the tape 143 gradually removes the film from the FOG glass module. After peeling, the FOG glass module grasped by the bonding robot 19 is photographed by the FOG bonding camera.

[0068] The film-peeling gripper 172 clamps one end of the film on the BLU backlight module. By rotating the film-peeling gripper 172 in conjunction with the movement of the bonding platform 1E, the film can be peeled off. The BLU bonding camera 1C takes a picture of the BLU backlight module after the film has been peeled off.

[0069] Based on the image information captured by the FOG bonding camera and the BLU bonding camera 1C, the bonding robot 19 is controlled to bond the FOG glass module after film removal to the BLU backlight module after film removal on the bonding platform 1E. Finally, the bonding platform 1E moves to the discharge position, and the second gripper 167 picks up the bonded screen product from the bonding platform 1E and transports it to the output line 18.

[0070] This completes the process of bonding and manufacturing screen products using a fully automated circular backlight assembly machine.

[0071] The fully automatic circular backlight assembly machine in this embodiment uses an FOG loading camera to photograph and position the FOG glass modules on the FOG input line, and controls the FOG loading robot to grab the FOG glass modules and adjust their position based on the photographed information. Similarly, it uses a BLU loading camera to photograph and position the BLU backlight modules on the BLU input line, and controls the BLU loading robot to grab the BLU backlight modules and adjust their position based on the photographed information. This machine can effectively position, grab, and transport circular products with high efficiency.

[0072] The FOG input line can effectively stop and position the FOG glass mold through two movable positioning blocks. The FOG loading robot can accurately adjust the product's orientation through the coordination of rotation and motion sensors, resulting in precise positioning and good fit.

[0073] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
