When the film tearing device 200 starts to tear the film, the film tearing roller 24 is relatively close to the display screen workpiece 700 to be torn, specifically, the film tearing roller 24 actively approaches the display screen workpiece 700, or the display screen workpiece 700 actively approaches the film tearing roller 24, which is not limited herein. After the film tearing roller 24 approaches the display screen workpiece 700, the film sticking area 241 at the initial position is adhered to one end of the film material 600, then the first driving device 23 drives the first mounting rack 22 to move towards the other end of the film material 600, and the roller also rolls along the surface of the display screen workpiece 700 along with the first mounting rack 22 and rolls towards the other end of the film material 600. The adhesion force of the film sticking area 241 to the film 600 is greater than the adhesion force between the film 600 and the display screen workpiece 700, so that one end of the film 600 is peeled off along with the rotation of the film sticking area 241, and along with the rotation of the film tearing roller 24, the film 600 is gradually peeled off from the display screen workpiece 700 towards the other end and then attached to the film tearing roller 24. It can be understood that the non-adhesive film area 241 of the film tearing roller 24 also generates a certain absorption force to the film 600, so that the peeled film 600 can be completely attached to the circumferential surface of the film tearing roller 24. The film material 600 attached to the circumferential surface of the film tearing roller 24 can keep a spreading state, and the film material 600 is prevented from curling and deforming under the action of self contraction stress, so that the film material 600 can be repeatedly used, and the waste of the peeled film material 600 is reduced.

The film material 600 is peeled off from the display screen workpiece 700 and then attached to the peeling roller 24. Referring to fig. 6 and 10, fig. 6 is a schematic diagram illustrating a film releasing process of the film tearing device 200 according to the present invention; fig. 10 is a schematic structural diagram of an embodiment of a medium film material 600 transferring device 400 of the present invention. The film material 600 transferring device 400 comprises a linear driving module 41 and a transferring platform 42 installed on the linear driving module 41. The film tearing roller 24 has a forward rotation stroke and a backward rotation stroke, and in the backward rotation stroke, the film tearing roller 24 lays the film material 600 on the transfer platform 42 located at the film receiving position.

The transfer platform 42 is a vacuum adsorption platform, the transfer platform 42 can move along the transverse direction, and the film connecting position is located on the moving track of the transfer platform 42. After the film tearing roller 24 peels the film material 600 off the display screen workpiece 700, the first driving device 23 can drive the film tearing roller 24 to move above the film splicing position, that is, above the transfer platform 42 located at the film splicing position. After the film tearing roller 24 moves above the transferring platform 42, the film tearing roller 24 and the transferring platform 42 are close to each other along the longitudinal direction, and the film tearing roller 24 can be actively close to the transferring platform 42 downwards, or the transferring platform 42 can be actively close to the film tearing roller 24 upwards, which is not limited here. The film tearing roller 24 finally carries the film material 600 against the transfer platform 42.

It should be noted that, in the film tearing process of the film tearing roller 24, that is, in the forward and forward rotation stroke of the film tearing roller 24, two ends of the film material 600 are defined as a peeling head end and a peeling tail end, respectively, the peeling head end is adhered by the adhesive film area 241 and is torn up first, and the peeling tail end is torn up last; after the peeling end of the film 600 is torn, the film tearing roller 24 stops rotating, and the peeling end is kept at the bottom of the periphery of the roller. Therefore, when the film tearing roller 24 abuts against the transfer platform 42, the peeling end of the film material 600, i.e. the end far away from the film sticking region 241, is firstly contacted with the transfer platform 42. After membrane material 600 and transfer platform 42 butt back, the vacuum adsorption function is opened to transfer platform 42, and the adsorption affinity of vacuum adsorption to membrane material 600 can be greater than the adhesion force between membrane material 600 and the dyestripping gyro wheel 24, is greater than the adhesion force of membrane material 600 to membrane material 241 even to can adsorb membrane material 600 on transfer platform 42.

It will be appreciated that the first to be attracted to the transfer platform 42 is the peel tip of the film 600; then, the first driving device 23 can drive the roller to move in the direction opposite to the film tearing direction, and the roller rolls on the transfer platform 42 in the direction opposite to the film tearing direction, that is, the film tearing roller 24 enters into the backward reverse stroke, so that other parts of the film material 600 can gradually approach and be adsorbed on the transfer platform 42, and finally, the adsorbed part is the peeling head end of the film material 600. The transfer platform 42 can absorb all parts of the film material 600, so that the film material 600 can keep a spreading state on the transfer platform 42, and the film material 600 is prevented from curling and deforming under the action of self contraction stress, thereby ensuring that the film material 600 can be effectively reused. Through the cooperation of the film tearing roller 24 and the transfer platform 42, the peeled film material 600 can be completely placed on the transfer platform 42, and then the film material 600 is transferred to the film laminating mechanism by the transfer platform 42, so that the film laminating mechanism can receive the film material and then stick the film material to the detected display screen workpiece 700.

The film tearing roller 24 is generally a hard roller, and has a high surface hardness, and if the film tearing roller directly contacts the display screen workpiece 700, the display screen workpiece 700 is damaged. The peripheral surface of the film tearing roller 24 is provided with a flexible contact layer, the flexible contact layer extends along the circumferential direction of the film tearing roller 24, and the film sticking area 241 is arranged on the surface of the flexible contact layer. The flexible contact layer can be a plastic layer or a plastic layer, and is not limited to the plastic layer, and only the flexible buffer performance is required. The contact force of the film tearing roller 24 to the display screen workpiece 700 can be reduced by the flexible contact layer, so that the display screen workpiece 700 is prevented from being damaged by the film tearing roller 24 in the film tearing process, and the protection effect on the display screen workpiece 700 is improved.

The film tearing device 200 further comprises a film material 600 detecting device (not shown) installed on the first mounting frame 22, wherein the film material 600 detecting device is located on one side of the film tearing roller 24 in the radial direction and is used for detecting whether the film material 600 is attached to the circumferential surface of the film tearing roller 24. The film material 600 detection device may be specifically a camera device, or an infrared sensing device, and is not limited herein, and only needs to detect whether the film material 600 is attached to the circumferential surface of the film tearing roller 24. The film material 600 detecting device may be installed at one side of the film tearing roller 24 in the lateral direction to effectively utilize the space around the film tearing roller 24. It will be appreciated that during operation of film tearing roller 24, film material 600 detection device will move transversely in synchronism with film tearing roller 24, but will not rotate with film tearing roller 24. Whether the film tearing roller 24 successfully tears off the film 600 can be detected by the film 600 detection device, if the film tearing is unsuccessful, the film 600 detection device can send an alarm through the alarm device and inform a user of the alarm, so that the user can conveniently adjust the film tearing device 200. Thus, the operational reliability of the film tearing device 200 can be ensured.

Tear film device 200 still including connect in the mounting panel of first mounting bracket 22, the mounting panel is located tear film roller 24 is horizontal ascending one side, membrane material 600 detection device install in the mounting panel. Membrane material 600 detection device installs in the mounting panel towards dyestripping gyro wheel 24's one side to can make the mounting panel play the enclosure protection effect to membrane material 600 detection device, avoid membrane material 600 detection device to be bumped and damaged by the accident at the removal in-process.

During the film tearing and releasing process, the film tearing roller 24 can be driven to roll by the friction force between the film tearing roller 24 and the display workpiece and the transfer platform 42, or can be actively rolled by the driving device. Tear film device 200 still including install in the driving motor of mounting bracket, driving motor is used for the drive tear film gyro wheel 24 rotates. The film tearing roller 24 is driven by the driving motor to actively roll in the film tearing and film placing processes, so that the efficiency of the film tearing and film placing processes can be improved, and the film tearing and film placing processes are more accurate and controllable. It can be understood that the driving line speed of the driving motor to the film tearing roller 24 can be consistent with the transverse driving speed of the first driving device 23 to the mounting rack, so as to ensure that the film tearing roller 24 rolls synchronously at the linear speed same as the transverse moving speed, thereby avoiding the damage of the film material 600 caused by uneven stress due to the speed difference, and improving the protection effect of the film material 600.

The output shaft of the driving motor can be directly connected with the film tearing roller 24 or indirectly connected through a transmission structure, and is not limited herein. In one embodiment, a rotating shaft is convexly arranged on the end surface of the film tearing roller 24, the mounting frame is provided with a shaft hole, the rotating shaft is rotatably matched with the shaft hole, and the tail end of the rotating shaft extends out of the shaft hole; the driving motor is positioned above the film tearing roller 24, and the output shaft of the driving motor is connected with one end of the rotating shaft extending out of the shaft hole through a transmission chain. The output shaft of driving motor is parallel with the pivot, and the output shaft of second drive form is located to driving chain pot head, and the pivot is located to the other end cover to realize driving motor to dyestripping gyro wheel 24's drive. The driving motor is arranged above the film tearing roller 24, so that the size of the whole film tearing device 200 in the transverse direction can be reduced, and the whole structure of the film tearing device 200 is more compact.

After the film tearing is finished, the film tearing roller 24 needs to keep the peeling tail end of the film material 600 at the position of the bottom of the circumferential surface of the film tearing roller; and after the film is put, the adhesive film area 241 is needed to be reset to the position at the bottom of the peripheral surface of the film tearing roller 24. The film tearing device 200 further comprises a controller (not shown) and an angle sensor, wherein the angle sensor is electrically connected with the controller, and the controller is electrically connected with the driving motor; the angle sensor is used for detecting the rotation angle of the film sticking area 241, and the controller is used for controlling the film tearing roller 24 to be kept at a preset rotation angle or controlling the film sticking area 241 to be reset to an initial position. Thus, in the film tearing process, the peeling tail end of the film material 600 can be stopped at the position of the bottom of the peripheral surface of the film tearing roller 24 by controlling the film tearing roller 24 to rotate by a preset angle; similarly, after the film is completely placed, the film tearing roller 24 is controlled to rotate by a preset angle to reset the adhesive film area 241 to the initial position, so as to prepare for the next film tearing action.

The air guide structure 25 may be installed between the second driving device 53 and the film tearing roller 24, the air inlet is used for externally connecting the air supply device, and the air outlet 251 is used for blowing the air flow to the peripheral surface of the film tearing roller 24. In the backward reverse stroke of the film tearing roller 24, i.e. the film placing process, the air supply device provides air flow to the air guide structure 25, and the air flow flows to the separation position of the film tearing roller 24 and the film material 600 along the circumferential surface of the film tearing roller 24, so as to promote the smooth separation of the film material 600 and the film tearing roller 24 and improve the film placing efficiency.

Specifically, as shown in fig. 6, on a radial section of the film tearing roller 24, a space below the air guide structure 25 is divided into a film removing side and a film supplying side by a vertical symmetry axis of the film tearing roller 24; in the backward reverse stroke of the film peeling roller 24, the film peeling roller 24 peels off the film material 600 on the peeling side, and the air outlet 251 faces the peeling side. It can be understood that, as the film tearing roller 24 rolls, the film material 600 on the film stripping side is separated from the film tearing roller 24 and adsorbed on the transfer platform 42, and the film supply side is gradually pressed toward the transfer platform 42. The air outlet 251 faces the part of the roller on the demoulding side, so that the airflow blowing to the circumferential surface of the film tearing roller 24 can be guided to the separation part of the film tearing roller 24 and the film material 600 more, and the effective utilization rate of the airflow is improved.
