Description

Technical Field

[0001] This application relates to the field of mobile phone assembly equipment, and in particular to a vertical film peeling and flipping bonding device. Background Technology

[0002] In the mobile phone screen assembly process, the protective film on the surface of the screen assembly needs to be removed first, and then the screen assembly is attached to the mobile phone frame. In a typical process, the screen assembly is supported horizontally on a carrier. First, a film removal device removes the film layer from the surface of the screen assembly. After the film is removed, a flipping and adsorption device picks up the screen assembly and flips it to the position where it is attached to the frame.

[0003] The above-mentioned general process has the following problems: First, when peeling the film in a horizontal state, the flexible waste film that is peeled off is prone to drooping due to gravity, which may cause the waste film to stick back to the surface of the screen component or get stuck in the film peeling mechanism, affecting the stability and yield of the film peeling process; Second, after the screen component is peeled off, it needs to undergo a large-angle flip from a horizontal state to a bonding state. During this process, the screen component undergoes redundant posture transformation, which increases the number of operation steps. Moreover, the stress state of the screen component during the posture transformation is complex, which may cause damage.

[0004] Therefore, how to reduce the risk of damage to screen components during the film removal and posture transformation process, and improve the continuity of the film removal and bonding processes, are technical problems that need to be solved in this field. Summary of the Invention

[0005] The purpose of this application is to provide a vertical film peeling and flipping bonding device that can reduce the risk of damage to screen components during film peeling and posture transformation.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A vertical film-tearing and flipping laminating device includes: a feeding belt for conveying a carrier;

[0008] A carrier is mounted on the feed conveyor belt. The carrier is equipped with a screen component clamping device, which is used to vertically clamp the screen component onto the carrier.

[0009] The alignment and lifting mechanism is located at the film-tearing station and is used to receive the carrier conveyed by the feeding belt and position it at the film-tearing station. The alignment and lifting mechanism includes a carrier clamping and releasing device, which is used to drive the screen assembly clamping device to release its clamping of the screen assembly.

[0010] A film-removing mechanism, including a screen assembly fixing device and at least one film-removing robotic arm;

[0011] The screen assembly fixing device includes a rotating base and a suction plate connected to the rotating base. The rotating base is configured to drive the suction plate to switch between a vertical state and a horizontal state. In the vertical state, the suction plate is used to adsorb the back of the screen assembly after it has been released from clamping.

[0012] The film-removing robot is used to remove the film layer on the surface of the screen assembly when the suction plate is in the vertical state and adsorbs the screen assembly; and after the film removal is completed, the rotating seat drives the suction plate and the screen assembly adsorbed thereon to flip to the horizontal state so as to cover the screen assembly on the middle frame.

[0013] A film-discarding mechanism, located on one side of the film-tearing mechanism, is used to receive and collect the waste film released by the film-tearing robot.

[0014] Furthermore, the screen assembly clamping device of the carrier includes two sets of opposing clamping blocks and a reset component corresponding to the clamping blocks. The reset component applies a reset force to the clamping blocks to bring the two sets of clamping blocks closer together to clamp the screen assembly. The carrier clamping release device includes a release push block and a release driving device. The release driving device drives the release push block to push the clamping blocks away from each other to overcome the reset force and release the screen assembly.

[0015] Furthermore, the film-tearing mechanism also includes a film-tearing Y-axis transverse movement module, and the film-tearing robot includes a first film-tearing robot and a second film-tearing robot, both of which are mounted on the film-tearing Y-axis transverse movement module;

[0016] The first film-tearing robot includes a first rotating gripper and a first take-up roller. The first take-up roller is mounted on the bottom of a clamp of the first rotating gripper. The first rotating gripper is configured to drive the first take-up roller to rotate synchronously through its own rotational motion while gripping and tearing the waste film, so as to wind the torn waste film onto the first take-up roller.

[0017] Furthermore, the second film-tearing robot has the same structure as the first film-tearing robot; the second film-tearing robot is used to tear up the waste film at the other end of the screen assembly and tear the waste film on the three sides of the screen assembly to the first film-tearing robot. Then, the first film-tearing robot and the second film-tearing robot move simultaneously to tear the entire waste film away from the screen assembly.

[0018] Furthermore, the screen assembly fixing device also includes a four-axis displacement platform and a mounting bracket. The mounting bracket is installed on the four-axis displacement platform, and the rotating seat is rotatably disposed within the mounting bracket. Locking devices are respectively provided on both sides of the mounting bracket. The locking devices are used to lock the rotating seat onto the mounting bracket when the rotating seat drives the suction plate to rotate to the horizontal state.

[0019] Furthermore, the locking device includes a first pressing block and a first driving cylinder, and a second pressing block is correspondingly provided on the side of the rotating seat. The first driving cylinder drives the first pressing block to press the second pressing block onto the mounting bracket to lock the rotating seat.

[0020] Furthermore, the suction plate is provided with multiple suction cups, pressure sensors, and buffer components. The buffer components include buffer springs, buffer frames, and buffer guide rails. The pressure sensors are disposed on the suction plate, the buffer frames are mounted on the pressure sensors, and are slidably connected to the rotating seat through the buffer guide rails on both sides. The buffer springs are mounted on the buffer frames.

[0021] Furthermore, the screen assembly fixing device also includes a secondary clamping device, which is disposed on both sides of the suction plate and is used to clamp the screen assembly from both sides after the suction plate adsorbs the screen assembly.

[0022] Furthermore, the film-dropping mechanism includes a film-dropping clamping device and a film-dropping cylinder; the film-dropping clamping device includes a film-dropping gripper, a film-dropping lifting cylinder for driving the film-dropping gripper to rise and fall, and a film-dropping lateral movement module for driving the film-dropping gripper to move laterally; the upper end of the film-dropping cylinder is a film-dropping port, the middle part is provided with a gripper outlet, and the side is provided with a clearance opening extending from the film-dropping port to the gripper outlet; the film-dropping clamping device is used to clamp the waste film released by the film-tearing robot and drag the waste film through the film-dropping port into the film-dropping cylinder; the film-dropping gripper moves at the clearance opening to the gripper outlet and releases the waste film, and then leaves from the gripper outlet.

[0023] Furthermore, the alignment and lifting mechanism also includes a lifting device and a blocking device. The blocking device includes a blocking roller and a blocking cylinder. The blocking cylinder drives the blocking roller to rise upward to block the movement of the carrier. The lifting device includes a lifting plate and a lifting cylinder. The lifting cylinder drives the lifting plate to move up and down to lift the carrier. The lifting plate is provided with a positioning pin. The positioning pin is used to cooperate with the positioning hole on the carrier to position the carrier.

[0024] The beneficial effects of this application are as follows:

[0025] Compared to conventional vertical film-peeling and laminating equipment, the technical solution provided in this application utilizes a carrier to vertically transport the screen assembly to the film-peeling station. The screen assembly is then held in place by a screen assembly fixing device, and a film-peeling robot performs the film-peeling operation. This allows the torn waste film to hang naturally under gravity, avoiding the problem of waste film easily sticking back to the screen assembly surface or getting stuck in the film-peeling mechanism, as is common in horizontal film-peeling methods. This improves the stability and success rate of the film-peeling process. Simultaneously, the rotating seat of the screen assembly fixing device can directly rotate the screen assembly from a vertical to a horizontal position after film peeling to cover the middle frame. This combines the screen assembly's orientation change and laminating action into one, eliminating the need for a separate flipping and handling step after film peeling. This reduces the risk of damage caused by multiple orientation changes and improves the continuity and overall efficiency of the film peeling and laminating processes. Attached Figure Description

[0039] Figure 14 A schematic diagram of the film-dropping mechanism according to an embodiment of this application is shown; Detailed Implementation

[0040] This application provides a vertically peeling and flipping bonding device. This device is used during mobile phone assembly to peel off the protective film from the surface of the screen assembly and then bond the screen assembly to the mobile phone frame.

[0041] Please see Figure 1 and Figure 2 As shown in the embodiment of this application, a vertical film-tearing and flipping laminating device includes a feeding pull belt 100, a barcode scanning mechanism 200, a carrier 300, an alignment and lifting mechanism 400, a film-tearing mechanism 500, a CCD alignment mechanism 600, and a film-dropping mechanism 700.

[0042] In this embodiment, two feeding conveyor belts 100 are provided, arranged side by side, for independently conveying the carriers 300. Each feeding conveyor belt 100 has a corresponding barcode scanning mechanism 200 on one side, located upstream of the film-tearing station. The barcode scanning mechanism 200 is used to acquire information about the components carried by the carriers 300 on the corresponding feeding conveyor belt 100, such as the serial number or batch information of a mobile phone frame component, to achieve traceability of the production process. The carriers 300 are respectively mounted on the corresponding feeding conveyor belts 100 and move with the feeding conveyor belts 100 to the film-tearing station.

[0043] Two sets of film-tearing mechanisms 500 are provided and are arranged across the two feeding belts 100. Specifically, the film-tearing Y-axis transverse module 530 of the film-tearing mechanism 500 extends along the direction across the two feeding belts 100, and the film-tearing robot on it can move between the film-tearing stations of the two feeding belts 100 to alternately perform film-tearing operations on the screen components from the carriers 300 of the two feeding belts 100.

[0044] With this setup, the two feeding belts 100 can feed materials alternately or simultaneously. When the carrier 300 on one feeding belt 100 is performing film tearing and bonding operations, the other feeding belt 100 can transport the carrier 300 or stand by, which greatly shortens the waiting time of the film tearing mechanism 500 and significantly improves the overall production cycle and equipment utilization rate.

[0045] Please refer to the following: Figure 3 The carrier 300 is equipped with a screen assembly clamping device 320 and a mobile phone mid-frame positioning and receiving groove 310. The mobile phone mid-frame positioning and receiving groove 310 is used to position and receive the mobile phone mid-frame. The screen assembly clamping device 320 is used to clamp the screen assembly on the carrier 300 in a vertical position.

[0046] The feed conveyor belt 100 is used to convey the carrier 300 along the conveying direction of the production line. The barcode scanning mechanism 200 is located on one side of the feed conveyor belt 100 and upstream of the film-tearing station. The barcode scanning mechanism 200 is used to obtain information about the components carried by the carrier 300, such as the serial number or batch information of the mobile phone frame component, to achieve traceability of the production process.

[0047] The carrier 300 is mounted on the feed conveyor belt 100 and moves with the feed conveyor belt 100 to the film-tearing station. Please refer to the following: Figure 3 The carrier 300 is equipped with a screen assembly clamping device 320 and a mobile phone mid-frame positioning and receiving groove 310. The mobile phone mid-frame positioning and receiving groove 310 is used to position and receive the mobile phone mid-frame. The screen assembly clamping device 320 is used to clamp the screen assembly on the carrier 300 in a vertical position.

[0048] The screen assembly clamping device 320 includes two sets of clamping blocks 321 and a reset component corresponding to each clamping block 321. The two sets of clamping blocks 321 are arranged opposite to each other and are respectively installed on both sides of the positioning and receiving groove 310 of the mobile phone frame. The reset component is located on the side of the clamping blocks 321 and is used to apply a reset force to the clamping blocks 321 to bring the two sets of clamping blocks 321 closer to each other, thereby vertically clamping and holding the screen assembly on the carrier 300.

[0049] In a preferred embodiment, the reset assembly includes a reset spring 322 and a limiting rod 323. The reset spring 322 is sleeved or mounted on the limiting rod 323, with one end abutting against the body of the carrier 300 and the other end abutting against the clamping block 321, for continuously pushing the clamping block 321 to move in the clamping direction.

[0050] Please see Figure 4 The alignment and lifting mechanism 400 is located at the film-tearing station, below the film-tearing mechanism 500. The alignment and lifting mechanism 400 is used to receive the carrier 300 conveyed by the feeding belt 100 and lift the carrier 300 from the feeding belt 100, thereby accurately positioning the carrier 300 at the film-tearing station.

[0051] The alignment and lifting mechanism 400 includes a blocking device 410, a lifting device 420, and a carrier clamping and releasing device 430.

[0052] The blocking device 410 is installed at the entrance end of the film-tearing station and includes a blocking roller 411 and a blocking cylinder 412. When the carrier 300 needs to stop at the film-tearing station, the blocking cylinder 412 drives the blocking roller 411 to rise and extend into the travel path of the carrier 300, thereby preventing the carrier 300 from continuing to move with the feed conveyor belt 100 and achieving initial stop positioning.

[0053] The lifting device 420 includes a lifting plate 421 and a lifting cylinder 422. The lifting cylinder 422 drives the lifting plate 421 to move up and down. When the carrier 300 is stopped by the blocking device 410, the lifting plate 421 rises and lifts the carrier 300, causing the carrier 300 to disengage from the feed conveyor belt 100. The lifting plate 421 is provided with a positioning pin 4211. During the lifting process, the positioning pin 4211 engages with the corresponding positioning hole on the bottom of the carrier 300 to accurately position the carrier 300.

[0054] The carrier clamping release device 430 is used for mechanical linkage with the screen assembly clamping device 320 on the carrier 300. The carrier clamping release device 430 includes a release guide rail 431, a release push block 432, and a release drive device 433 (e.g., a release cylinder). After the carrier 300 is lifted and positioned, the release drive device 433 drives the release push block 432 to move along the release guide rail 431, causing the release push block 432 to insert into and push the clamping blocks 321 of the screen assembly clamping device 320. This drives the clamping blocks 321 to overcome the reset force of the reset spring 322 and move away from each other, thereby releasing the clamping of the screen assembly and preparing for the film peeling mechanism 500 to remove the screen assembly. Through this passive unlocking method, the carrier 300 itself does not need to be equipped with a power source, simplifying the structure.

[0055] Please see Figures 5 to 9 The film-peeling mechanism 500 includes a screen assembly fixing device 510, at least one film-peeling robot, and a film-peeling Y-axis transverse translation module 530.

[0056] like Figure 6 As shown, the screen assembly fixing device 510 is used to grip and fix the screen assembly during the film peeling process. It includes a four-axis displacement platform 511, a mounting bracket 512, a rotating seat 513, a rotation drive device 514, a suction plate 515, and a secondary clamping device 516.

[0057] A four-axis displacement platform 511 drives a mounting bracket 512 mounted thereon to move in multiple degrees of freedom to achieve precise alignment with the screen assembly on the carrier 300. The mounting bracket 512 is mounted on the four-axis displacement platform 511. A rotary seat 513 is rotatably disposed within the mounting bracket 512; specifically, the rotary seat 513 is rotatably connected to the mounting bracket 512 via a rotating shaft. A rotary drive device 514 is disposed on one side of the mounting bracket 512 and is drively connected to the rotary seat 513, for driving the rotary seat 513 to rotate about a horizontal axis, thereby allowing the rotary seat 513 to switch between a vertical and a horizontal state.

[0058] like Figure 7 As shown, the suction plate 515 is fixedly connected to the rotating base 513 and rotates together with the rotating base 513. The suction plate 515 is provided with multiple suction cups 5151 for adsorbing the back of the screen assembly. When the rotating base 513 is in a vertical position, the adsorption surface of the suction plate 515 is in a vertical position to adapt to the screen assembly vertically clamped on the carrier 300.

[0059] In a preferred embodiment, the suction plate 515 is further provided with a pressure sensor 5152 and a buffer assembly 518. Please refer to the following for details. Figure 9 The buffer assembly 518 includes a buffer spring 5181, a buffer frame 5182, and a buffer guide rail 5183. A pressure sensor 5152 is mounted on the suction plate 515 to detect the contact pressure during screen assembly adsorption in real time. The buffer frame 5182 is mounted on the pressure sensor 5152 and slidably connected to the rotating seat 513 via the buffer guide rails 5183 on both sides. The buffer spring 5181 is mounted on the buffer frame 5182, with one end abutting against the buffer frame 5182 and the other end abutting against the rotating seat 513. When the suction plate 515 approaches and adsorbs the screen assembly, the buffer spring 5181 is compressed, providing flexible mechanical cushioning. Simultaneously, the pressure sensor 5152 provides real-time feedback on the contact pressure. The two work together to prevent excessive pressure during adsorption from damaging the screen and to compensate for minor positional deviations, ensuring reliable and safe adsorption.

[0060] like Figure 8 As shown, secondary clamping devices 516 are respectively disposed on both sides of the suction plate 515 and mounted on the mounting bracket 512. The secondary clamping device 516 includes a clamping plate 5161 and a clamping drive device 5162. After the suction plate 515 adsorbs the screen assembly, the clamping drive device 5162 drives the clamping plate 5161 to clamp the edges of the screen assembly from both sides, providing additional mechanical clamping force in addition to vacuum adsorption, ensuring that the screen assembly is firmly fixed during the subsequent film removal process, and preventing displacement or detachment due to the film removal tension.

[0061] like Figure 8As shown, in a preferred embodiment, locking devices 517 are respectively provided on both sides of the mounting bracket 512. The locking devices 517 are used to lock the rotating seat 513 onto the mounting bracket 512 after the rotating seat 513 drives the suction plate 515 and screen assembly to a horizontal position, ensuring stability during the bonding process. Specifically, the locking device 517 includes a first pressure block 5171 and a first drive cylinder 5172. A second pressure block 5131 is correspondingly provided on the side of the rotating seat 513. When the rotating seat 513 rotates to a horizontal position, the first drive cylinder 5172 drives the first pressure block 5171 to extend, pressing the second pressure block 5131 against the mounting bracket 512, thereby achieving rigid locking of the rotating seat 513, preventing slight shaking during bonding, and improving bonding accuracy.

[0062] like Figure 10 As shown, the film-tearing robot is mounted on the film-tearing Y-axis transverse module 530 and can move along the Y-axis direction on the film-tearing Y-axis transverse module 530. In a preferred embodiment, two film-tearing robots are provided, namely a first film-tearing robot 520 and a second film-tearing robot (with the same structure as the first film-tearing robot).

[0063] like Figure 11 As shown, a membrane R is provided on the screen assembly, which is arranged around the side of the screen assembly through ends A and B.

[0064] Please see Figure 10 and Figure 12 The first film-tearing robot 520 includes a first X-axis transverse module 521, a first Z-axis transverse module 522, a first film-tearing arm 523, a first rotary clamping drive device 524, a first rotary gripper 525, and a first take-up roller 526.

[0065] The first Z-axis transverse module 522 is mounted on the film-tearing Y-axis transverse module 530, the first X-axis transverse module 521 is mounted on the first Z-axis transverse module 522, and the first film-tearing arm 523 is mounted on the first X-axis transverse module 521. Through the combined drive of the film-tearing Y-axis transverse module 530, the first X-axis transverse module 521, and the first Z-axis transverse module 522, the first film-tearing arm 523 can move in three-dimensional space.

[0066] A first rotary clamping drive device 524 is mounted at the end of the first film-tearing arm 523. A first rotary gripper 525 is mounted on the first rotary clamping drive device 524 and is driven by the first rotary clamping drive device 524 to perform a rotary motion. The first rotary gripper 525 has two clamps for gripping.

[0067] The first take-up roller 526 is installed at the bottom of one of the clamps of the first rotating gripper 525, close to the clamping position. During operation, the first rotating gripper 525 first clamps the waste film on the upper edge of the screen assembly, and then, driven by the coordinated movement modules of the X, Z, and Y axes, moves away from the screen assembly, tearing off the waste film. Simultaneously, the first rotating clamping drive device 524 drives the first rotating gripper 525 to rotate around its own axis, causing the first take-up roller 526 to rotate synchronously. Because the first take-up roller 526 is close to the clamping position, the torn waste film is immediately wound onto it. This synchronous action of "tearing and winding simultaneously" effectively prevents the flexible waste film torn in a vertical position from sagging, sticking back to the screen assembly surface, or getting stuck in the mechanism due to gravity, significantly improving the stability and reliability of the tearing process.

[0068] like Figure 13 As shown, the structure of the second film-tearing robot is the same as that of the first film-tearing robot 520. During the film-tearing operation, the first and second film-tearing robots work together. The second film-tearing robot grips the waste film at the other end of the screen assembly and tears off the waste film from the right, bottom, and left sides of the screen assembly, moving it to the side where the first film-tearing robot 520 is located. Finally, the first and second film-tearing robots together grip both ends of the completely torn waste film and move simultaneously to the film-discarding mechanism 700 for film disposal.

[0069] The CCD alignment mechanism 600 is located in front of the film-peeling mechanism 500. Before the film peeling operation, the CCD alignment mechanism 600 can be used to visually position the screen assembly and the mobile phone frame, guiding the four-axis displacement platform 511 to perform precise alignment. After the film peeling is completed, the rotating seat 513 has flipped the screen assembly onto the frame. At this time, the CCD alignment mechanism 600 can re-inspect the bonded assembly to confirm the bonding accuracy and product quality.

[0070] like Figure 14 As shown, the film dropping mechanism 700 is disposed on one side of the film tearing mechanism 500 and is used to receive and collect the waste film released by the film tearing robot. The film dropping mechanism 700 includes a film dropping clamping device 710 and a film dropping cylinder 720.

[0071] The film-dropping clamping device 710 includes a film-dropping pneumatic gripper 711, a film-dropping lifting cylinder 712, and a film-dropping lateral movement module (not shown in the figure). The film-dropping pneumatic gripper 711 is mounted on the film-dropping lifting cylinder 712 and is driven by the film-dropping lifting cylinder 712 to perform lifting movements. The film-dropping lifting cylinder 712 is mounted on the film-dropping lateral movement module and is driven by the film-dropping lateral movement module to perform lateral movements.

[0072] The film-discharging cylinder 720 has a cylindrical structure with an open film-discharging port 721 at the top for feeding waste film. A claw-shaped outlet 723 is provided on the middle side wall of the film-discharging cylinder 720. A clearance opening 722 is provided on the side of the film-discharging cylinder 720. The clearance opening 722 is a long and narrow opening that extends downward from the edge of the film-discharging port 721 to the claw-shaped outlet 723.

[0073] In a preferred embodiment, the top of the film discarding cylinder 720 may also be provided with an air blowing structure for blowing air toward the inside of the film discarding cylinder 720 to assist the waste film from falling.

[0074] During the film-dropping operation, the first and second film-tearing robots move the waste film to the film-dropping mechanism 700. The film-dropping gripper 711 of the film-dropping clamping device 710 moves to the second film-tearing robot and clamps the root of the waste film (i.e., the end closest to the clamping point of the second film-tearing robot). Subsequently, the film-dropping lateral movement module drives the film-dropping gripper 711 to move laterally, dragging the waste film above the film-dropping opening 721 of the film-dropping cylinder 720 and downward into the film-dropping cylinder 720. During this process, the arm part of the film-dropping gripper 711 is located within the clearance opening 722 and can move freely up and down along the clearance opening 722. When the film-dropping gripper 711 descends to the position of the gripper exit opening 723, the film-dropping gripper 711 releases and releases the waste film, which falls into the bottom of the film-dropping cylinder 720 under the action of gravity and the air blowing structure (not shown in the figure). Subsequently, driven by the film-discarding lifting cylinder 712 and the film-discarding lateral movement module, the film-discarding gripper 711 moves laterally out of the film-discarding cylinder 720 from the gripper outlet 723, completing the film-discarding action and resetting. This structure ensures the smooth delivery of waste film and effectively prevents waste film from being carried out of the cylinder along with the gripper's return.

[0075] The following is combined Figures 1 to 14 The working process of the vertical film tearing and flipping bonding device provided in this application is described in its entirety.

[0076] First, the carrier 300, carrying the phone's mid-frame and screen components, is conveyed on the feeding conveyor belt 100. As it passes the barcode scanning mechanism 200, the mechanism scans and obtains the identification information of the components on the carrier 300. Subsequently, the carrier 300 is conveyed to the film-peeling station.

[0077] The blocking cylinder 412 of the alignment lifting mechanism 400 drives the blocking roller 411 to rise, stopping the carrier 300 at the predetermined position of the film-tearing station. Then, the lifting cylinder 422 drives the lifting plate 421 to rise, and the positioning pin 4211 on the lifting plate 421 engages with the positioning hole at the bottom of the carrier 300, lifting the carrier 300 away from the feed belt 100 and positioning it precisely.

[0078] At this time, the screen assembly fixing device 510 is driven by the four-axis displacement platform 511 to move the suction plate 515 directly above the screen assembly, and it is precisely aligned by the guidance of the CCD alignment mechanism 600. The rotating seat 513 has been pre-rotated to a vertical position, so that the suction plate 515 is in a vertical position. The suction plate 515 moves closer to the back of the screen assembly, and the suction cup 5151 contacts the screen assembly and begins to adsorb. During the adsorption process, the buffer component 518 provides cushioning, and the pressure sensor 5152 ensures that the adsorption force is safe and controllable. After the adsorption is stable, the clamping plate 5161 of the secondary clamping device 516 clamps the screen assembly from both sides to achieve double fixation.

[0079] Then, the release drive device 433 of the carrier clamping release device 430 drives the release push block 432 to extend, pushing the clamping block 321 on the carrier 300 to open against the force of the reset spring 322, thereby releasing the vertical clamping of the screen assembly.

[0080] Next, the rotating gripper 525 of the first film-tearing robot 520 grasps the waste film on the upper edge of the screen assembly and begins to tear the film through the coordinated movement of the X and Z axis modules and the film-tearing Y-axis lateral movement module. While tearing the film, the rotating gripper 525 rotates itself, driving the take-up roller 526 to simultaneously reel in the torn waste film. The second film-tearing robot grasps the other end of the waste film and, together, tears the waste film from the three sides to one side. Finally, the two film-tearing robots work together to completely tear the entire waste film away from the screen assembly.

[0081] After the film is peeled off, the peeling robot arm holds the waste film and moves it to the film discarding mechanism 700. The film discarding gripper 711 of the film discarding device 710 grips the root of the waste film and drags it into the film discarding cylinder 720 to complete the waste collection. At the same time, the rotation drive device 514 of the screen assembly fixing device 510 drives the rotating seat 513 to move the suction plate 515 and the screen assembly adsorbed on it from the vertical position to the horizontal position, and directly covers the screen assembly onto the mobile phone frame that has been positioned on the carrier 300. After flipping into place, the locking device 517 locks the rotating seat 513 to ensure the bonding accuracy. Subsequently, the CCD alignment mechanism 600 performs a re-inspection on the bonded assembly.

[0082] Finally, all mechanisms are reset, the carrier 300 is lowered and released, and the feed conveyor belt 100 sends it out of the film-tearing station, completing a full work cycle.

[0083] The technical features of the embodiments described above can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification.

[0084] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
