The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Fig. 1 to 13 show a film laminating apparatus 100 according to an embodiment of the present invention.

As shown in fig. 1 to 3, the film sticking apparatus 100 includes: a film tearing mechanism 10 and a film sticking mechanism 20. Wherein a film tearing mechanism 10 is used to carry a roll of protective film and separate the protective film from the base paper. The film sticking mechanism 20 is used to stick the protective film to the outer side of the middle frame 200.

The film sticking apparatus 100 will be further described below with reference to fig. 4 to 13 in addition to fig. 1 to 3.

As shown in fig. 4 and 5, the film tearing mechanism 10 includes: the feeding device comprises a feeding wheel 11, a receiving wheel 12, a material distributing table 13 positioned between the feeding wheel 11 and the receiving wheel 12, and a first driver 14 connected with the receiving wheel 12. The film sticking mechanism 20 includes: a rotary base 21, a second driver (not shown) connected with the rotary base 21, a bracket 22 arranged in a sliding way, a third driver 23 connected with the bracket 22, a press wheel 24 arranged on the bracket 22, a press rod 25 arranged on the bracket 22 in a sliding way, and a fourth driver 26 connected with the press rod 25. The pressing rod 25 is positioned on one side of the pressing wheel 24 close to the material distribution table 13.

In the present embodiment, the first actuator 14 and the second actuator are both motors, and the third actuator 23 and the fourth actuator 26 are both air cylinders, and the first actuator 14, the second actuator, the third actuator 23, and the fourth actuator 26 may be replaced with other types of actuators on the premise that the corresponding operation requirements are satisfied.

Further, as shown in fig. 4, in the present embodiment, the rotary base 21 is provided with a positioning rod 211 and a first vacuum chuck (not shown). When the middle frame 200 is placed on the rotary base 21, the middle frame 200 is positioned by the positioning rod 211 and then is adsorbed by the first vacuum chuck to be stabilized on the rotary base 21. In other embodiments, the center frame 200 may be fixed by providing an electromagnet on the rotary base 21 or by using a clamp or the like.

Considering that the shape of the middle frame 200 of the current electronic product is mainly rectangular, and when the rectangular middle frame 200 rotates along with the rotary seat 21, the short side and the long side of the middle frame 200 need different moving spaces, that is, the material separating table 13 needs to keep a proper distance from the rotary seat 21 to prevent the rotary seat 21 from impacting the material separating table 13 when rotating, or the material separating table 13 obstructs the rotation of the rotary seat 21. On the other hand, if the long side of the middle frame 200 is used as a reference standard, the distance between the dispensing table 13 and the rotary base 21 is always kept long, and when the protective film is adhered to the short side of the middle frame 200, the distance between the dispensing table 13 and the rotary base 21 is long, so that the protective film is likely to be deviated, which is not favorable for ensuring the accuracy of film adhesion. Therefore, in order to solve the above problem, the film tearing mechanism 10 and the film sticking mechanism 20 are designed to be interlocked, and the distance between the material separating table 13 and the rotary base 21 is adjusted according to the short side and the long side of the middle frame 200, so that the material separating table 13 can be as close to the rotary base 21 as possible without interfering with the rotation of the rotary base 21. As shown in fig. 4 and 5, in the present embodiment, the film tearing mechanism 10 may further include: a slide 15 arranged slidably, a first link 16 connected to the slide 15, and a first cam 17 connected to the first link 16. The discharge wheel 11, the receiving wheel 12 and the distributing table 13 are respectively mounted on a slide 15. The first cam 17 is connected to the second driver. The first cam 17 is provided with a guide rail corresponding to the outer contour of the rotary seat 21. The guide rail is slidably connected to the first link 16. Considering that the middle frame 200 of most electronic products is rectangular, in order to avoid the material distribution table 13 from obstructing the movement of the rotating base 21, when the rotating base 21 rotates, the sliding base 15 is driven to move along with the first cam 17 and the first connecting rod 16, so as to adjust the distance between the material distribution table 13 and the rotating base 21, and on the premise of not obstructing the rotation of the rotating base 21, the material distribution table 13 is closer to the rotating base 21, which is beneficial to improving the precision of the protective film adhesion.

As shown in fig. 4, in the present embodiment, the material-distributing table 13 is provided with a corner portion 131 provided toward the rotary base 21. When the protective film and the base paper move to the corner portion 131, because the hardness of the protective film is greater than that of the base paper, and the protective film is cut in sections in advance, the starting end of the protective film will automatically separate from the base paper at the corner portion 131 of the material separating table 13 and extend toward the rotating base 21, and the base paper will continue to move toward the material receiving wheel 12 along the scraping portion under the driving of the material receiving wheel 12.

In the above film pasting mechanism 20, how to put the middle frame 200 into the rotating seat 21 is not explained, but in practical applications, a corresponding material grabbing structure may be provided in the film pasting device 100, or manual material feeding may be adopted, or an external robot may be used. Here, the film sticking apparatus 100 is provided with the material catching mechanism 30 for realizing the feeding and discharging of the middle frame 200, for example. As shown in fig. 1 to 3, in the present embodiment, the film sticking apparatus 100 may further include: a material grabbing mechanism 30. The material grasping mechanism 30 includes: a robot arm 31. Automatic feeding and automatic discharging of the rotary seat 21 can be realized by using the manipulator 31, and the automation degree of the equipment is improved.

Further, the structural arrangement of the manipulator 31 may be various, for example, a numerical control multi-axis robot is adopted, or a slide rail and a clamping jaw are used for implementation. For example, as shown in fig. 6 and 7, in the present embodiment, the robot hand 31 includes: a hand grip 311, a fifth actuator 312 coupled to the hand grip 311, a second link 313 coupled to the hand grip 311, and a second cam 314 coupled to the second link 313. During operation, the fifth actuator 312 drives the gripper 311 to swing, and the gripper 311 moves along a preset track under the limitation of the second link 313 and the second cam 314, and the movement of the manipulator 31 is realized by a hardware setting mode, so that the difficulty of numerical control is reduced. For example, in the present embodiment, the second cam 314 is used to decompose the motion of the hand grip 311 into a vertical motion, a rotational motion, and a horizontal motion, which respectively correspond to the vertical slide rail, the arc slide rail, and the horizontal slide rail on the second cam 314. The vertical movement corresponds to the movement direction of the hand grip 311 for vertically picking up and putting down the middle frame 200, the horizontal movement corresponds to the movement direction of the hand grip 311 for transferring the middle frame 200 to the rotary base 21 or taking down the middle frame 200 from the rotary base 21, and the rotary movement is used as the transition movement between the vertical movement and the horizontal movement.

In this embodiment, the fifth driver 312 is a motor, and in other embodiments, the fifth driver 312 may be another type of driver on the premise that the movement of the mounting seat 32 is satisfied.

The grip 311 may grip the middle frame 200 in various ways, such as clamping, vacuum suction, electromagnet suction, etc., as shown in fig. 6, in this embodiment, the grip 311 is vacuum suction, and the grip 311 is provided with a second vacuum chuck 3111. The gripper 311 uses the second vacuum chuck 3111 to suck the middle frame 200 to grip the material, so as to avoid scratching the middle frame 200. It is understood that in other embodiments, an electromagnet may be used to attract the middle frame 200, that is, the hand grip 311 is provided with an electromagnet, so as to avoid scratching the middle frame. For the clamping manner, that is, the gripper 311 is provided with the clamping jaw, a soft rubber sleeve can be sleeved on the clamping jaw, so that the probability of scratching the middle frame 200 is reduced.

In addition, as shown in fig. 6 and 5, in the present embodiment, the material grabbing mechanism 30 may further include: a mounting seat 32 arranged in a sliding way and a sixth driver 33 connected with the mounting seat 32. The robot 31 is mounted on the mount 32. The sixth driver 33 is used for driving the mounting seat 32 to move, so that the position of the gripper 311 when releasing the middle frame 200 can be adjusted, the material taking position and the material placing position of the gripper 311 are staggered, and the middle frame 200 before and after film pasting is prevented from being confused.

In the present embodiment, the sixth actuator 33 is an air cylinder, and in other embodiments, the sixth actuator 33 may be another type of actuator on the premise that the movement of the mounting seat 32 is satisfied.

Further, in order to further improve the automation degree of the operation of the apparatus, as shown in fig. 8, in another embodiment, the film sticking apparatus 100a may further include: a conveyor belt 40. The film tearing mechanism 10, the film sticking mechanism 20 and the material grabbing mechanism 30 are respectively arranged on the conveyor belt 40. The conveyor belt 40 is provided with a first material rail 41 and a second material rail 42. The first material rail 41 and the second material rail 42 are arranged in a staggered manner. The material grabbing mechanism 30 is located between the first material rail 41 and the second material rail 42. The transfer of the middle frame 200 before and after film pasting can be realized by utilizing the conveyor belt 40, and the middle frames 200 before and after film pasting respectively transfer on different material rails, so that the automation of the film pasting operation of the middle frame 200 is improved.

Further, the conveyor belt 40 may be further provided with a material blocking unit 43. The material blocking unit 43 is located on the first material rail 41 and is arranged close to the material grabbing mechanism 30. The middle frame 200 before film pasting is moved to the position of the material grabbing mechanism 30 on the first material rail 41, and is intercepted by the material blocking unit 43 to wait for the material grabbing mechanism 30 to grab. As shown in fig. 8, in the present embodiment, the material blocking unit 43 includes: the material baffle 431 is arranged on the first material rail 41 and close to one end of the material grabbing mechanism 30, and when the middle frame 200 flows to the material grabbing mechanism 30 along the conveyor belt 40, the middle frame is intercepted by the material baffle 431.

The operation principle of the film sticking apparatus 100 described above will be briefly described with reference to fig. 9 to 13.

As shown in fig. 9, the manipulator 31 of the grasping mechanism 30 grasps the middle frame 200 from a predetermined material taking point (e.g., the first material rail 41 of the conveyor belt 40). In combination with the structure of the robot 31 in the present embodiment, at this time, the hand 311 moves vertically downward and sucks the middle frame 200 through the second vacuum chuck 3111 under the restriction of the vertical-section slide rail of the second cam 314.

As shown in fig. 10, the gripper 311 ascends first under the restriction of the second cam 314 and then enters the horizontal slide rail under the guidance of the circular arc slide rail of the second cam 314, the gripper 311 is changed from the vertical posture to the horizontal posture toward the rotary base 21 and then approaches toward the rotary base 21 along the horizontal slide rail of the second cam 314, and finally the middle frame 200 is placed on the rotary base 21.

As shown in fig. 11, the rotary base 21 starts to rotate, when the rotary base 21 rotates to a predetermined angle position, the starting end of the protective film enters a predetermined bonding position, the bracket 22 carries the pressing wheel 24 and the pressing rod 25 to move downwards for a certain distance, and then, the pressing rod 25 is driven by the fourth driver 26, the pressing rod 25 moves downwards further and presses the starting end of the protective film on the middle frame 200, so that the starting end of the protective film is bonded with the middle frame 200.

As shown in fig. 12, the fourth driver 26 drives the pressing rod 25 to reset first, and the rotary base 21 continues to rotate, so that the subsequent portion of the protective film is adhered to the middle frame 200 along the outer side of the middle frame 200, the pressing wheel 24 still presses the outer side of the middle frame 200, and the protective film adhered to the outer side of the middle frame 200 is pressed and leveled by the pressing wheel 24. In this case, the horizontal distance between the material separating table 13 and the center of the rotation shaft of the rotating base 21 in fig. 11 and 12 may be compared, and when the rotating base 21 rotates, the horizontal distance between the slide carriage 15 and the rotating base 21 is adjusted according to the outer contour of the middle frame 200, and the slide carriage is as close as possible to the rotating base 21 without interfering with the rotation of the rotating base 21.

As shown in fig. 13, when the rotary base 21 rotates until the protective film of the segment is used up, the rotary base 21 stops. The gripper 311 removes the filmed middle frame 200 from the rotary base 21 and places it at a predetermined blanking position (e.g., the second material rail 42 of the conveyor belt 40).

The film sticking device 100 is used for placing the protective film material roll on the discharging wheel 11, connecting the starting end of the backing paper of the protective film material roll to the receiving wheel 12, and driving the receiving wheel 12 to rotate by the first driver 14 so as to drive the protective film material roll to rotate to discharge the protective film. The protective film is cut into sections in advance and adhered to the base paper, and when the protective film moves to the distribution table 13, the starting end of the protective film is peeled from the base paper and extends toward the rotary base 21. The middle frame 200 is placed on the rotary base 21, the second driver drives the rotary base 21 to rotate, and the middle frame 200 also rotates along with the rotary base 21. When the starting end of the protective film reaches the preset film pasting position, the third driver 23 drives the support 22 to approach the rotating base 21, the fourth driver 26 drives the pressing rod 25 to approach the rotating base 21, the starting end of the protective film is pressed on the outer side of the middle frame 200 through the pressing rod 25, the starting end of the protective film is bonded with the middle frame 200, and the pressing rod 25 resets after pressing is completed. Then, the rotary base 21 continues to rotate, the film tearing mechanism 10 continues to discharge, and the pressing wheel 24 mounted on the bracket 22 presses the protective film adhered on the middle frame 200 to play a role in pressing and leveling. Through the above design, utilize tear film mechanism 10 to realize the automatic blowing of protection film to utilize the depression bar 25 among the pad pasting mechanism 20 to simulate manual work's finger to press, make the initiating terminal of protection film can bond on center 200, then, rethread pinch roller 24 further compresses tightly and trowels the protection film, thereby improves the degree of automation and the work efficiency of center 200 pad pasting.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
