In the present specification, the exemplary description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the described specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0023] Please refer to Figure 1 and Figure 8 , Figure 1 is a structural schematic diagram of a film stripping device 100 under an embodiment of the present application; Figure 8 is Figure 7 an enlarged schematic diagram of the II area. The present application provides a film stripping device 100, which comprises a clamping assembly 10, a rotary driver 20 and a translation driver 30. The clamping assembly 10 is used to clamp a release film 300 attached to a workpiece 200. The rotary driver 20 is connected with the clamping assembly 10 and can drive the clamping assembly 10 to rotate around a rotation axis. The translation driver 30 is connected with the rotary driver 20 and can drive the clamping assembly 10 to move in a direction perpendicular to the rotation axis. The translation driver 30 and the rotary driver 20 are used to cooperatively drive the clamping assembly 10 to strip the release film 300 from the workpiece 200.

[0024] Specifically, the film stripping device 100 further comprises a rack 90, the translation driver 30 is installed on the rack 90, and the rotary driver 20 is arranged on the top side of the translation driver 30. In the present embodiment, a photoelectric detection assembly is arranged between the rotary driver 20 and the clamping assembly 10, and the starting and stopping of the rotary driver 20 and the rotation angle of the rotary driver 20 are controlled through the electrical signal of the photoelectric detection assembly.

[0025] By setting the rotary driver 20 and the translation driver 30, the rotary driver 20 can drive the clamping assembly 10 to rotate around the rotation axis, so as to drive the clamping assembly 10 to tear one end of the release film 300 from the workpiece 200, and the translation driver 30 can drive the clamping assembly 10 to move in a direction perpendicular to the rotation axis. After the one end of the release film 300 is torn, the translation driver 30 cooperates with the rotary driver 20 to provide the release film 300 with a combined motion of translation and rotation, so that the workpiece 200 suffers a smaller force during the peeling process, thereby reducing the risk of the workpiece 200 being damaged.

[0026] In some embodiments, considering that the partial release film 300 is too firmly attached to the workpiece 200, forcibly tearing off can easily cause the workpiece 200 to be damaged. A rotation load sensor (not shown) is arranged between the clamping assembly 10 and the rotary driver 20. The load sensor is electrically connected to the rotary driver 20 and the translation driver 30, and is used to obtain the torque load of the clamping assembly 10 around the rotation axis during the film tearing process. When the torque load exceeds a preset value, the rotary driver 20 and the translation driver 30 stop driving, so as to avoid the workpiece 200 being damaged.

[0027] Further, the rotary driver 20 can control the rotation speed of the clamping assembly 10 according to the torque load, so that the torque load is always below the preset value.

[0028] In an embodiment of this implementation, please refer to Figure 1 and Figure 8 , in order to make the force distribution of the workpiece 200 uniform during the tearing process of the release film 300, the driving direction of the translation driver 30 and the rotation axis are both parallel to the plane where the release film 300 is located.

[0029] In this embodiment, the workpiece 200 is an FPC, which is horizontally placed on a related bearing structure, and the release film 300 is attached to the bottom surface of the FPC, and the plane where the release film 300 is located is parallel to the horizontal plane. The driving direction of the translation driver 30 is parallel to the first horizontal direction 91, and the rotation axis is parallel to the second horizontal direction 92.

[0030] In other embodiments, the workpiece 200 can also be other devices, and the placement form thereof can also be specifically set according to actual working conditions.

[0031] In an embodiment of this implementation, please refer to Figure 1 , Figure 3 and Figure 8 , Figure 3 is Figure 1Figure 1 is a schematic view of a structure of a clamping assembly 10 and a rotary driver 20 in a film stripping apparatus 100 according to an embodiment of the present application. In order to achieve clamping of the release film 300, the clamping assembly 10 comprises a clamping driver 11 and two clamping blocks 12, the clamping driver 11 is arranged on the rotary driver 20 and connected with the two clamping blocks 12 so as to drive the two clamping blocks 12 to clamp the release film 300.

[0032] Specifically, the driving direction of the clamping driver 11 is perpendicular to the rotation axis, so that the two clamping blocks 12 can better clamp the upper and lower sides of the release film 300 which is parallel to the horizontal plane.

[0033] In one embodiment of the embodiment, please refer to Figure 1 , Figure 3 and Figure 8 , the driving direction of the clamping driver 11 is perpendicular to the rotation axis. In this way, the rotation torque provided by the rotary driver 20 can fully act on the release film 300, so that the release film 300 can be more reliably torn off.

[0034] In this embodiment, the driving direction of the clamping driver 11 is parallel to the vertical direction 93, and the rotation axis is parallel to the horizontal direction.

[0035] In one embodiment of the embodiment, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 8 , Figure 4 is a partial schematic view of the clamping assembly 10 of Figure 3 . In order to further improve the reliability of tearing off the release film 300, the two clamping blocks 12 each have a sawtooth surface 121, and the shapes of the two sawtooth surfaces 121 are matched and used to clamp the release film 300. In this way, the two clamping blocks 12 can fully clamp the release film 300, reducing the risk of the release film 300 escaping from between the two clamping blocks 12 during tearing, thereby improving the reliability of film tearing.

[0036] It can be understood that the sawtooth surface 121 is a surface with alternating protrusions and recesses, similar to the tooth shape of a saw. The sawtooth surface 121 of one of the clamping blocks 12 is used to fit one side of the release film 300, and the sawtooth surface 121 of the other clamping block 12 is used to fit the other side of the release film 300. The shapes of the two sawtooth surfaces 121 are matched to engage and hold the release film 300.

[0037] In one embodiment of the embodiment, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 8 , Figure 2 is a schematic view of the film stripping apparatus 100 according to Figure 1 from another perspective; Figure 5is Figure 1 a structural schematic view of the waste collecting assembly 50 in the film stripping apparatus 100. In order to improve the automation degree of film stripping, the film stripping apparatus 100 comprises a switching driver 40 and the waste collecting assembly 50, the switching driver 40 is connected with the rotating driver 20 to be able to drive the clamping assembly 10 to move the stripped release film 300 to the top side of the waste collecting assembly 50. In this way, the switching driver 40 can cooperate with the waste collecting assembly 50 to realize the automation of the release film 300.

[0038] Specifically, the waste collecting assembly 50 comprises a waste cylinder 51, an air suction driver (not shown) and a lifting driver 53, the waste cylinder 51 is located at the bottom side of the clamping assembly 10 and is used to receive the release film 300 released by the clamping assembly 10, the air suction driver is in communication with the waste cylinder 51 to be able to suck the air in the waste cylinder 51 to take away the release film 300 in the waste cylinder 51, and the lifting driver 53 is connected with the waste cylinder 51 to be able to drive the waste cylinder 51 to lift. It can be understood that the presence of the lifting driver 53 can shorten the distance between the waste cylinder 51 and the clamping assembly 10 during waste discharge, so as to facilitate the receiving of the release film 300, reduce the risk of the release film 300 falling outside the waste cylinder 51, and increase the distance between the waste cylinder 51 and the clamping assembly 10 during film stripping to avoid interference and improve reliability.

[0039] Specifically, the driving direction of the switching driver 40 is perpendicular to the driving direction of the translation driver 30, i.e. parallel to the second horizontal direction 92.

[0040] In an embodiment of this embodiment, please refer to Figure 1 , Figure 2 and Figure 8 , the film stripping apparatus 100 comprises a blowing assembly 60, which is used to provide ion wind to the release film 300 on the clamping assembly 10. It can be understood that there may be static electricity between the release film 300 after stripping and the clamping assembly 10, due to the adsorption effect of static electricity, so that after the clamping assembly 10 releases the release film 300, the release film 300 will be adsorbed on the clamping assembly 10, and cannot complete the waste discharge by gravity. By setting the blowing assembly 60, the ion wind provided by the blowing assembly 60 can remove the static electricity of the release film 300, so as to facilitate the release film 300 to fall into the waste collecting assembly 50.

[0041] Specifically, the blowing assembly 60 comprises a mounting rod 61 and a gas nozzle 62, the mounting rod 61 is mounted on the rack 90 and connected with the gas nozzle 62, and the gas nozzle 62 is located at the top side of the clamping assembly 10 and can blow down ion wind along the vertical direction 93.

[0042] In an embodiment of this embodiment, please refer to Figure 1 , Figure 2 ,Figure 6 、 Figure 7 and Figure 8 , Figure 6 is a structural schematic view of the carrier jig 80 and the turntable 85; Figure 7 is Figure 6 an enlarged schematic view of the I area of the The film stripping apparatus 100 further comprises a press assembly 70 and a carrier jig 80. The carrier jig 80 comprises a connecting plate 81, a fixed block 82 and a moving block 83. The fixed block 82 is fixed on the connecting plate 81 and is used to support a part of the workpiece 200. The moving block 83 is in sliding fit with the connecting plate 81 and is provided with an elastic member 831 therebetween. The moving block 83 is used to support another part of the workpiece 200, and the release film 300 is located at the bottom side of the other part. The press assembly 70 is used to abut against the moving block 83 and drive the moving block 83 to compress the elastic member 831. In this way, the press assembly 70 can drive the moving block 83 to press down the elastic member 831, so as to make the release film 300 hang in the air, thereby providing space for the release film 300 to be stripped. Moreover, the presence of the elastic member 831 can reset the moving block 83 after the film stripping is completed.

[0043] In this embodiment, the film stripping apparatus 100 further comprises a turntable 85, and the carrier jig 80 is in plurality. The plurality of carrier jigs 80 are installed on the turntable 85, and each carrier jig 80 is loaded with four workpieces 200. The elastic member 831 is configured as a spring, and the elastic deformation direction of the spring is parallel to the vertical direction 93.

[0044] Specifically, each carrier jig 80 comprises four fixed blocks 82 and two moving blocks 83. Each moving block 83 supports two adjacent workpieces 200.

[0045] In one embodiment of this implementation, please refer to Figure 1 , Figure 2 and Figure 8 In order to realize the downward driving of the moving block 83, the press assembly 70 comprises a press driver 71 and a pressing plate 72. The press driver 71 is connected with the pressing plate 72 and can drive the pressing plate 72 to move towards the moving block 83.

[0046] Specifically, the pressing plate 72 is in sliding fit with the rack 90 and is provided with an elastic support member 721 therebetween.

[0047] In this embodiment, the film stripping apparatus 100 further comprises an inductor 86. The inductor 86 is arranged on the pressing plate 72 and is used to detect the workpiece 200, so as to judge whether the release film 300 on the workpiece 200 is successfully stripped, thereby improving the reliability of the film stripping.

[0048] In one embodiment of this implementation, please refer to Figure 1 , Figure 2 and Figure 7In order to improve the film tearing efficiency, the number of the clamping assemblies 10 and the rotary drivers 20 is multiple, and they are connected one by one, and the multiple rotary drivers 20 are arranged on the translation driver 30. In this way, the multiple rotary drivers 20 cooperate with the translation driver 30 to realize the film 300 tearing of the multiple workpieces 200, thereby improving the film tearing efficiency.

[0049] Specifically, the multiple rotary drivers 20 are mounted on the top side of the linkage plate 21, the bottom side of the linkage plate 21 is connected with the switching driver 40, the translation driver 30 is mounted on the rack 90 and connected with the switching driver 40.

[0050] In the embodiment, the number of the rotary drivers 20, the clamping assemblies 10, the waste barrels 51 and the air nozzles 62 is four, so as to realize the film tearing of the four workpieces 200 on the bearing fixture 80 at the same time. It can be understood that, since the rotation of each clamping assembly 10 is driven by the corresponding rotary driver 20, the rotation angle in the film tearing process of each film 300 can be independently controlled, so as to improve the applicability.

[0051] The embodiments of the application are described in detail above with reference to the drawings, but the application is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the application. In addition, the embodiments of the application and the features in the embodiments can be combined with each other without conflict.
