[0105] The following describes in detail various embodiments of the present invention in conjunction with the accompanying drawings.

[0106] Please also see Figure 1 and Figure 2 The present embodiment provides a bending mechanism 10 for folding a portion of a flexible component 11. In this embodiment, the flexible component 11 is a flat cable. However, based on the description of this application, those skilled in the art will appreciate that the flexible component 11 may also be other similar components.

[0107] Specifically, the bending mechanism 10 includes a clamping assembly 12, a first transmission assembly 13, and a second transmission assembly 14. The clamping assembly 12 is used to clamp a portion of the flexible member 11 and includes a first clamping block 121 and a second clamping block 122. The output ends of the first transmission assembly 13 and the second transmission assembly 14 are connected to the first clamping block 121 and the second clamping block 122, respectively, to drive the first clamping block 121 and the second clamping block 122 to rotate.

[0108] At least one of the first transmission assembly 13 and the second transmission assembly 14 can be driven independently to move the first clamping block 121 and the second clamping block 122 away from each other and into contact with each other, thereby clamping a portion of the flexible member 11. The first transmission assembly 13 and the second transmission assembly 14 can be driven synchronously to rotate the first clamping block 121 and the second clamping block 122 synchronously, thereby folding up the clamped portion of the flexible member 11.

[0109] In this embodiment, the initial state of the bending mechanism 10 is that the first clamping block 121 is in contact with the second clamping block 122. First, the first transmission assembly 13 is driven independently, causing it to drive the first clamping block 121 away from the second clamping block 122. Second, a portion of the flexible member 11 is placed on the first clamping block 121. Then, the second transmission assembly 14 is driven independently, causing it to drive the second clamping block 122 to contact the first clamping block 121, thereby clamping a portion of the flexible member 11. Finally, the first and second transmission assemblies 13, 14 are driven synchronously, causing the first and second clamping blocks 121, 122 to rotate synchronously, thereby folding the portion of the flexible member 11 clamped by the first and second clamping blocks 121, 122.

[0110] In some embodiments, a groove shaped like a portion of the flexible member 11 may be provided on the side where the first clamping block 121 and the second clamping block 122 are in contact with each other, so as to more accurately clamp a portion of the flexible member 11 .

[0111] In the above-mentioned bending mechanism 10, by independently driving the first transmission component 13 or the second transmission component 14, the first clamping block 121 and the second clamping block 122 are moved away from and fitted together, thereby clamping a portion of the flexible member 11, and then by synchronously driving the first transmission component 13 and the second transmission component 14, the first clamping block 121 and the second clamping block 122 are rotated synchronously, thereby folding the portion of the flexible member 11 clamped by the first clamping block 121 and the second clamping block 122, replacing the manual bending method, improving the bending accuracy and efficiency, the overall structure is easy to disassemble, and the overall layout saves more space.

[0112] Please see further Figure 3 In some embodiments, the first transmission assembly 13 includes a first rotating shaft 131, and the second transmission assembly 14 includes a second rotating shaft 141. The second rotating shaft 141 is disposed within the first rotating shaft 131, with an end of the second rotating shaft 141 extending out of the first rotating shaft 131. The first clamping block 121 is mounted on the end of the first rotating shaft 131, and the second clamping block 122 is mounted on the end of the second rotating shaft 141.

[0113] In the above embodiment, the flexible member 11 may be a flat cable. The first rotating shaft 131 and the second rotating shaft 141 are coaxially arranged, which enables the first clamping block 121 and the second clamping block 122 to fit more closely, thereby clamping a portion of the flat cable.

[0114] Please see further Figure 1 In some embodiments, the first transmission assembly 13 further includes a first rack 132 and a first gear 133 that mesh with each other, and a first rotating shaft 131 connected to the first gear 133. The first rack 132 can be driven to move, thereby driving the first clamping block 121 to rotate via the first gear 133 and the first rotating shaft 131. The second transmission assembly 14 further includes a second rack 142 and a second gear 143 that mesh with each other, and a second rotating shaft 141 connected to the second gear 143. The second rack 142 can be driven to move, thereby driving the second clamping block 122 to rotate via the second gear 143 and the second rotating shaft 141.

[0115] In this embodiment, the first rack 132 and the second rack 142 are arranged in parallel, and the driving ends of the first rack 132 and the second rack 142 are kept on the same side, which can simplify the driving operation and improve practicality.

[0116] Please see further Figure 1In some embodiments, the first gear 133 and / or the first clamp 121 are detachably connected to the first rotating shaft 131, and the second gear 143 and / or the second clamp 122 are detachably connected to the second rotating shaft 141, so as to allow the first gear 133 and the second gear 143 to be re-engaged with different teeth on the first rack 132 and the second rack 142, respectively, to thereby adjust the opening angle of the clamping assembly 12 and / or the folding degree of the flexible member 11.

[0117] In the above embodiment, an external force is used to drive the rack to move, which in turn drives the gear to rotate, and the gear in turn drives the shaft to rotate, thereby achieving the effect of driving the first clamping block 121 and the second clamping block 122 to rotate. This transmission method can adjust the opening angle of the first clamping block 121 and the second clamping block 122 and the degree of folding of the flexible member 11 by adjusting the first gear 133 and the second gear 143 to re-engage with different teeth on the first rack 132 and the second rack 142, respectively. It is simple to operate, easy to disassemble, and has a wide range of applications.

[0118] In some embodiments, the bending mechanism 10 further includes a support base 15 having a through hole 151. The first rotating shaft 131 is adapted to fit within the through hole 151, and the first rotating shaft 131 and the second rotating shaft 141 pass through the through hole 151. The first clamping block 121 and the second clamping block 122 are disposed on one side of the support base 15, and the first gear 133, the second gear 143, the first rack 132, and the second rack 142 are disposed on the other side of the support base 15.

[0119] In the above embodiment, the support seat 15 plays a supporting role, which can ensure that the first transmission component 13 and the second transmission component 14 are always in a balanced state with the first clamping block 121 and the second clamping block 122, thereby assisting the first transmission component 13 and the second transmission component 14 to achieve the transmission effect.

[0120] Please see further Figure 1 In some embodiments, the bending mechanism 10 further includes an elastic component 16. The elastic component 16 is used to synchronously drive the first transmission component 13 and the second transmission component 14. The first transmission component 13 and the second transmission component 14 can be driven in steps by an external force, so that the first clamping block 121 and the second clamping block 122 are in contact with each other, thereby clamping a portion of the flexible member 11. During the step-by-step driving of the first transmission component 13 and the second transmission component 14 by the external force, the elastic component 16 accumulates elastic potential energy, which is then used to synchronously drive the first transmission component 13 and the second transmission component 14.

[0121] For example, the external force may be a thrust applied by an operator to the first transmission assembly 13 and the second transmission assembly 14 , or may be a thrust applied by an automated driving device to the first transmission assembly 13 and the second transmission assembly 14 .

[0122] In some embodiments, the elastic assembly 16 includes a first spring 161 and a second spring 162. The first spring 161 and the second spring 162 are connected to the first rack 132 and the second rack 142, respectively. When driven by an external force, the first rack 132 and the second rack 142 independently move in a first direction A, thereby causing the first clamp 121 and the second clamp 122 to mate, thereby clamping a portion of the flexible member 11. At the same time, the first spring 161 and the second spring 162 accumulate elastic potential energy. After the external force is removed, the elastic potential energy drives the first rack 132 and the second rack 142 to move synchronously in a second direction B, thereby folding the flexible member 11. The first direction A is opposite to the second direction B.

[0123] In this embodiment, first, external force drives the first rack 132 to move along the first direction A, the first rack 132 drives the first gear 133 to rotate along the third direction R, the first gear 133 drives the first rotating shaft 131 to rotate along the third direction R, the first rotating shaft 131 drives the first clamping block 121 to rotate along the third direction R to leave the second clamping block 122, at this time, the first spring 161 contracts under the pressure of the first rack 132, and accumulates elastic potential energy; secondly, external force drives the second rack 142 to move along the first direction A, the second rack 142 drives the second gear 143 to rotate along the third direction R, the second gear 143 drives the second rotating shaft 141 to rotate along the third direction R, the second rotating shaft 141 drives the second clamping block 122 along the third direction R. The flexible member 11 is rotated in the third direction R toward the first clamping block 121 to clamp a portion of the flexible member 11. At this time, the second spring 162 contracts under the pressure of the second rack 142, accumulating elastic potential energy. Then, after the external force is removed, the first spring 161 and the second spring 162 simultaneously stretch naturally, utilizing this elastic potential energy to drive the first rack 132 and the second rack 142 to move synchronously in the second direction B. The first rack 132 and the second rack 142 respectively drive the first gear 133 and the second gear 143 to rotate in the fourth direction. The first gear 133 and the second gear 143 then simultaneously drive the first clamping block 121 and the second clamping block 122 to rotate in the fourth direction, thereby folding a portion of the flexible member 11. The fourth direction is opposite to the third direction R. In the above embodiment, by utilizing the elastic potential energy of the elastic component 16 to synchronously drive the first transmission component 13 and the second transmission component 14, no additional automated drive equipment is required for further driving. This results in high bending efficiency, simple operation, and low operating costs.

[0124] In some specific embodiments, the first transmission assembly 13 includes a first rotating shaft 131, a first rack 132, a first gear 133 and a first spring 161, and the second transmission assembly 14 includes a second rotating shaft 141, a second rack 142, a second gear 143 and a second spring 162. A series of operations such as clamping a flexible member and bending a flexible member are achieved by driving the rack to move by an external force and resetting the rack by a spring. Based on the description of the present application, it can be expected that the purpose of the invention of the present application can still be achieved after some parts are transformed. For example, the first clamping block 121 and the second clamping block 122 are directly driven by the asynchronous forward rotation and synchronous reverse rotation of the two motors, or the first clamping block 121 and the second clamping block 122 are directly driven after being transmitted by gears, belts, etc.

[0125] Please also see Figure 2 and Figure 3 In some embodiments, the bending mechanism 10 further includes a jig 17, a plurality of support blocks 18, and two slide rails 19. The jig 17 is used to support a workpiece including the flexible member 11, and the support seat 15 is disposed on the jig 17. A plurality of support blocks 18 are disposed on the jig 17, and each support block 18 is provided with a slide groove 181. The two slide rails 19 are respectively connected to the first rack 132 and the second rack 142, and respectively cooperate with the slide grooves 181 on the plurality of support blocks 18 to define the movement direction of the first rack 132 and the second rack 142.

[0126] In this embodiment, the first rack 132 and the second rack 142 are respectively arranged on the jig 17 through at least two support blocks 18, so as to better limit the moving direction of the first rack 132 and the second rack 142. At the same time, the slide rail 19 cooperates with the support block 18 to enhance the movement flexibility of the first rack 132 and the second rack 142.

[0127] In some embodiments, the elastic assembly 16 further includes two connecting posts 163. The two connecting posts 163 are respectively arranged along the extension direction of the first rack 132 and the second rack 142. One end of the first spring 161 and the second spring 162 are respectively sleeved on the two connecting posts 163, and the other ends of the first spring 161 and the second spring 162 are connected to the jig 17.

[0128] In the above embodiment, the two connecting posts 163 fixed to the slide rail 19 can limit the compression and extension directions of the first spring 161 and the second spring 162, preventing the first spring 161 and the second spring 162 from tilting. One end of the first spring 161 and the second spring 162 is fixed to the jig 17. The jig 17 can resist the first spring 161 and the second spring 162 during the compression process, allowing the first spring 161 and the second spring 162 to accumulate elastic potential energy. The first rack 132 and the second rack 142 can respectively support the other ends of the first spring 161 and the second spring 162, ensuring that the first rack 132 and the second rack 142 are linked to the first spring 161 and the second spring 162.

[0129] Please also see Figure 1 and Figure 2 In some embodiments, a stop block 152 is provided at the bottom of the support base 15 , and the first clamping block 121 can abut against the stop block 152 during the rotation process.

[0130] In the above embodiment, the stop block 152 can limit the first clamping block 121 during the rotation of the first clamping block 121 away from the second clamping block 122, so that the first clamping block 121 remains flush with the surface of the workpiece carried by the fixture 17, avoiding the first clamping block 121 from rotating to the lower side of the workpiece, causing the flexible component 11 to be repeatedly bent.

[0131] Please see further Figure 4 In some embodiments, a stop block 171 is provided on the jig 17. The first transmission assembly 13 includes a first supporting plate 134, and the second transmission assembly 14 includes a second supporting plate 144. The first rack 132 is disposed on the first supporting plate 134, and the second rack 142 is disposed on the second supporting plate 144. The stop block 171 is disposed across the first and second supporting plates 134, 144 on a side away from the first and second springs 161, 162, and is used to block the first and second racks 132, 142 from moving in the second direction B driven by the first and second springs 161, 162, thereby preventing the flexible member 11 from being excessively bent.

[0132] In the above embodiment, by adjusting the position of the stopping block 171 , the moving distance of the first rack 132 and the second rack 142 along the second direction B can be adjusted, thereby adjusting the degree to which the flexible member 11 is folded.

[0133] Please see further Figure 6 The embodiment of the present application also provides a bending method for a flexible member 11, using the bending mechanism 10 of the above embodiment, wherein the initial state of the bending mechanism 10 is as follows Figure 5A shown.

[0134] Specifically, the method comprises the following steps:

[0135] S10, driving the first transmission assembly to rotate the first clamping block along the third direction and away from the second clamping block.

[0136] Specifically, an external force drives the first rack 132 to move along the first direction A, the first rack 132 drives the first gear 133 to rotate along the third direction R, the first gear 133 drives the first rotating shaft 131 to rotate along the third direction R, and the first rotating shaft 131 drives the first clamping block 121 to rotate along the third direction R away from the second clamping block 122 until the second clamping block 122 rotates to contact the support seat 15. Figure 5B shown.

[0137] S20, placing a portion of the flexible component to be clamped onto the first clamping block.

[0138] Specifically, when the second clamping block 122 rotates to contact the stop block 152 on the support seat 15, the part of the flexible member 11 that needs to be clamped is placed on the first clamping block 121, as shown in FIG. Figure 5B shown.

[0139] S30, driving the second transmission assembly to rotate the second clamping block along the third direction to approach the first clamping block, so as to clamp a portion of the flexible component.

[0140] Specifically, the external force drives the second rack 142 to move along the first direction A, the second rack 142 drives the second gear 143 to rotate along the third direction R, the second gear 143 drives the second rotating shaft 141 to rotate along the third direction R, and the second rotating shaft 141 drives the second clamping block 122 to rotate along the third direction R close to the first clamping block 121 to clamp a portion of the flexible member 11, such as Figure 5C shown.

[0141] S40, synchronously driving the first transmission assembly and the second transmission assembly to rotate the first clamping block and the second clamping block simultaneously along the fourth direction to fold up a portion of the flexible component.

[0142] Specifically, in steps S10 and S30, driven by an external force, the first rack 132 and the second rack 142 move in the first direction A, respectively abutting against the first spring 161 and the second spring 162, causing the first spring 161 and the second spring 162 to accumulate elastic potential energy. After the external force is removed, the first spring 161 and the second spring 162 utilize their elastic potential energy to drive the first rack 132 and the second rack 142 to move synchronously in the second direction B. The first rack 132 and the second rack 142 respectively drive the first gear 133 and the second gear 143 to rotate in the fourth direction. Furthermore, the first gear 133 and the second gear 143 simultaneously drive the first clamp 121 and the second clamp 122 to rotate in the fourth direction, thereby folding a portion of the flexible member 11. The fourth direction is opposite to the third direction R.

[0143] In the bending method of the flexible member 11 provided in the above embodiment, the first transmission assembly 13 and the second transmission assembly 14 are driven separately to make the first clamping block 121 and the second clamping block 122 move away from and fit together, thereby clamping a portion of the flexible member 11, and then the first transmission assembly 13 and the second transmission assembly 14 are driven synchronously to make the first clamping block 121 and the second clamping block 122 rotate synchronously, thereby folding the portion of the flexible member 11 clamped by the first clamping block 121 and the second clamping block 122, thereby replacing the manual bending method and improving the bending accuracy and efficiency.

[0144] Please see further Figure 7 The embodiment of the present application further provides a film laminating system 100 for laminating a workpiece. A flexible component 11 is connected to the workpiece, and a portion of the flexible component 11 is located above the film laminating area of ​​the workpiece.

[0145] Specifically, the film laminating system 100 includes the bending mechanism 10, the movable platform 20, the drive mechanism 30, and the film laminating mechanism 40 of the aforementioned embodiment. The movable platform 20 is equipped with at least two fixtures 21 for supporting the workpiece, each of which is provided with the bending mechanism 10. The drive mechanism 30 includes a first drive assembly 31 and a second drive assembly 32, which are respectively used to drive the first transmission assembly 13 and the second transmission assembly 14. The film laminating mechanism 40 is used to attach the film to the film laminating area of ​​the workpiece.

[0146] The drive mechanism 30 and the film laminating mechanism 40 are disposed outside the movable stage 20. The movable stage 20 is used to transfer the workpiece from the working area of ​​the drive mechanism 30 to the working area of ​​the film laminating mechanism 40. It should be noted that the working area of ​​the drive mechanism 30 refers to the working station of the drive mechanism 30, that is, the driving action of the drive mechanism 30 must be completed at this station. The working area of ​​the film laminating mechanism 40 refers to the working station of the film laminating mechanism 40, that is, the film laminating action of the film laminating mechanism 40 must be completed at this station.

[0147] In the film laminating system 100 of the above embodiment, under the driving action of the driving mechanism 30, the bending mechanism 10 folds up a part of the flexible component 11, and the mobile platform 20 moves the workpiece from the working area of ​​the driving mechanism 30 to the working area of ​​the film laminating mechanism 40. The film laminating mechanism 40 attaches the film to the film laminating area of ​​the workpiece, which can automatically realize the bending of the flexible component 11 and cooperate with the film laminating mechanism 40 to laminat the workpiece, thereby realizing film laminating automation and effectively improving film laminating efficiency.

[0148] Please see further Figure 8 In some embodiments, the first drive assembly 31 includes a first drive cylinder 33 and a first push block 34. The first drive cylinder 33 is used to drive the first push block 34, so that the first push block 34 pushes the first rack 132 to move along the first direction A. The second drive assembly 32 includes a second drive cylinder 35 and a second push block 36. The second drive cylinder 35 is used to drive the second push block 36, so that the second push block 36 pushes the second rack 142 to move along the first direction A. In the above embodiment, separate cylinders and push blocks are provided for the first rack 132 and the second rack 142, thereby achieving independent driving of the first rack 132 and the second rack 142.

[0149] In some embodiments, the film laminating system 100 further includes a material transport robot (not shown) and a lifting mechanism 50. The material transport robot is used to transfer the workpiece to the fixture 21. The lifting mechanism 50 is disposed below the drive mechanism 30. The output end of the lifting mechanism 50 is connected to a mounting plate 51, and the drive mechanism 30 is mounted on the mounting plate 51.

[0150] Among them, the lifting mechanism 50 is used to drive the driving mechanism 30 to switch between the first position and the second position: when in the first position, the output ends of the first driving component 31 and the second driving component 32 are aligned with the first transmission component 13 and the second transmission component 14 respectively; when in the second position, the first driving component 31 and the second driving component 32 are driven by the lifting device to outside the moving path of the material transport robot.

[0151] In this embodiment, when in the first position, the output ends of the first drive component 31 and the second drive component 32 are aligned with the first transmission component 13 and the second transmission component 14 respectively, and the first drive component 31 and the second drive component 32 separately drive the first transmission component 13 and the second transmission component 14 to drive the first clamping block 121 and the second clamping block 122 to clamp a part of the flexible component 11; when in the second position, the first drive component 31 and the second drive component 32 are driven by the lifting device to the outside of the moving path of the material transport robot, and the output ends of the first drive component 31 and the second drive component 32 are no longer aligned with the first transmission component 13 and the second transmission component 14, and the first transmission component 13 and the second transmission component 14 are driven simultaneously to drive the first clamping block 121 and the second clamping block 122 to fold up a part of the flexible component 11.

[0152] Please see further Figure 9 In some embodiments, the film laminating system 100 further includes a bracket 60 . The bracket 60 is disposed outside the movable platform 20 and is connected to a telescopic mechanism 61 . The output end of the telescopic mechanism 61 is connected to a limit rod 62 .

[0153] Among them, the telescopic mechanism 61 is used to drive the limit rod 62 to switch between the retracted position and the extended position: when in the retracted position, the limit rod 62 is moved outside the moving path of the jig 21; when in the extended position, at least a portion of the limit rod 62 is located on the path of synchronous rotation of the first clamping block 121 and the second clamping block 122, and the free end of the limit rod 62 extends above the area between the connection point between the flexible member 11 and the workpiece and a portion of the flexible member 11, so as to resist the flexible member 11 during the process of synchronous rotation of the first clamping block 121 and the second clamping block 122 to fold up a portion of the flexible member 11, thereby preventing the flexible member 11 from being excessively bent or disconnected from the workpiece.

[0154] In this embodiment, after the material transport robot places the workpiece on the jig 21, the telescopic mechanism 61 drives the limit rod 62 to extend, so that at least a portion of the limit rod 62 is located in the path of synchronous rotation of the first clamping block 121 and the second clamping block 122. The free end of the limit rod 62 extends above the area between the connection point between the flexible member 11 and the workpiece and a portion of the flexible member 11, so as to contact the flexible member 11 during the process of synchronous rotation of the first clamping block 121 and the second clamping block 122 to fold up a portion of the flexible member 11, thereby preventing the flexible member 11 from being excessively bent or disconnected from the workpiece. When a portion of the flexible member 11 is folded up, the telescopic mechanism 61 drives the limit rod 62 to retract, so that the limit rod 62 is moved out of the movement path of the jig 21, thereby preventing it from blocking the movable platform 20 from transferring the workpiece carried by the jig 21.

[0155] Please see further Figure 10In some embodiments, each jig 21 includes two bearing points and two sets of bending mechanisms 10, each bearing point corresponds to each set of bending mechanisms 10, and each bearing point is used to bear a workpiece.

[0156] Please see further Figure 7 The film pasting system 100 includes two sets of film pasting mechanisms 40, one set of film pasting mechanisms 40 is used to attach the film to the film pasting area of ​​the workpiece carried by one of the bearing acupoints, and the other set of film pasting mechanisms 40 is used to attach the film to the film pasting area of ​​the workpiece carried by another bearing acupoint.

[0157] Furthermore, the driving mechanism 30 includes two groups of first driving assemblies 31 and second driving assemblies. Each group of first driving assembly 31 and second driving assembly 32 is used to drive the first transmission assembly 13 and the second transmission assembly 14 of each group of bending mechanisms 10 respectively.

[0158] Please see further Figure 9 The output end of the telescopic mechanism 61 is connected to two limiting rods 62. The free end of each limiting rod 62 is capable of extending above the area between the connection point and a portion of the flexible member 11 on each workpiece. For example, the two limiting rods 62 can be connected to the output end of the telescopic mechanism 61 via a connecting plate 63, so that each limiting rod 62 can correspond to the flexible member 11 of the workpiece carried by each bearing point.

[0159] In some embodiments, each set of film-sticking mechanisms 40 includes a film-sticking supply component 41, an image shooting component 42, and a film-sticking robot (not shown). The film-sticking supply component 41 is used to provide a film for attaching to the film-sticking area of ​​the workpiece. The image shooting component 42 is directed toward the movable platform 20 to obtain image data of the film-sticking area of ​​the workpiece carried by the fixture 21 on the movable platform 20, so as to assist the film-sticking robot in attaching the film to the film-sticking area of ​​the workpiece.

[0160] In the above embodiment, by providing two bearing acupoints on the fixture 21 and providing two film-sticking mechanisms 40 corresponding to the two bearing acupoints, the film-sticking efficiency can be effectively improved.

[0161] Please see further Figure 11 In some embodiments, the film laminating system 100 further includes a visual inspection mechanism 70. The visual inspection mechanism 70 is located outside the movable stage 20 and is used to inspect whether the workpieces to which the film is applied meet the film laminating standards. The material transport robot is also used to transport workpieces that meet the film laminating standards and those that do not meet the standards to different locations. For example, workpieces that meet the film laminating standards are transported to a finished product tray, while workpieces that do not meet the film laminating standards are transported to a recycling tray.

[0162] The visual inspection mechanism 70 is disposed adjacent to the drive mechanism 30, and the movable stage 20 is further used to transfer the workpiece from the working area of ​​the film laminating mechanism 40 to the working area of ​​the visual inspection mechanism 70, and vice versa. It should be noted that the working area of ​​the visual inspection mechanism 70 refers to the working station of the visual inspection mechanism 70, that is, the inspection operation of the visual inspection mechanism 70 must be completed at this station.

[0163] In the above embodiment, a visual inspection mechanism 70 is added to the film pasting system 100 to detect whether the workpiece with the film attached thereto passing through the film pasting mechanism 40 meets the film pasting standards. Then, the workpieces that meet the film pasting standards and those that do not meet the film pasting standards are respectively moved to different positions by the material transport robot, thereby avoiding confusion between the workpieces that meet the film pasting standards and those that do not meet the film pasting standards, and further avoiding the workpieces that do not meet the film pasting standards affecting the subsequent processes.

[0164] Please see further Figure 8 In some embodiments, the film pasting system 100 further includes a plurality of sensors 80 and a controller (not shown). The plurality of sensors 80 are evenly arranged on the mobile carrier 20. The sensors 80 are arranged corresponding to the driving mechanism 30, the film pasting mechanism 40, and the visual inspection mechanism 70, and are used to send a corresponding start signal when the jig 21 is transferred to the working area of ​​the driving mechanism 30, the film pasting mechanism 40, and the visual inspection mechanism 70. The controller is used to receive the start signal sent by the plurality of sensors 80 to control the start of the driving mechanism 30, the film pasting mechanism 40, and the visual inspection mechanism 70. By arranging sensors 80 at corresponding positions of the mobile carrier 20, it is possible to assist the controller in determining when to send a start signal to the driving mechanism 30, the film pasting mechanism 40, and the visual inspection mechanism 70, thereby further realizing the automation of film pasting.

[0165] In this embodiment, four jigs 21 are installed on the mobile platform 20. These jigs 21 are evenly spaced, meaning that each jig 21 forms a 90-degree angle with its neighbor. The drive mechanism 30, two film-applying mechanisms 40, and visual inspection mechanism 70 are positioned to correspond to each jig 21. The presence of four jigs 21 on the mobile platform 20 allows the drive mechanism 30, two film-applying mechanisms 40, and visual inspection mechanism 70 to operate synchronously, effectively improving film-applying efficiency.

[0166] Please see further Figure 12 The present application also provides a film application method for applying a film to a film application area of ​​a screen assembly using the film application system 100 of the above embodiment. The screen assembly is connected to a flexible cable, and the film application area includes an area blocked by the flexible cable. The film application method includes the following steps:

[0167] S100: The lifting mechanism drives the driving mechanism to the first position, so that the output ends of the first driving assembly and the second driving assembly are aligned with the first transmission assembly and the second transmission assembly respectively.

[0168] Specifically, when the driving mechanism 30 is in the first position, the output ends of the first driving assembly 31 and the second driving assembly 32 are aligned with the first transmission assembly 13 and the second transmission assembly 14 respectively.

[0169] S200: The first driving assembly drives the first transmission assembly, so that the first transmission assembly drives the first clamping block to rotate along the third direction and away from the second clamping block.

[0170] Specifically, the first driving assembly 31 drives the first rack 132 to move along the first direction A, the first rack 132 drives the first gear 133 to rotate along the third direction R, the first gear 133 drives the first rotating shaft 131 to rotate along the third direction R, and the first rotating shaft 131 drives the first clamping block 121 to rotate along the third direction R to leave the second clamping block 122 until the second clamping block 122 rotates to contact the support seat 15, as shown in FIG. Figure 5B shown.

[0171] S300: Place the unfilmed screen assembly on a fixture, and place the portion of the cable that needs to be clamped on the first clamping block.

[0172] Specifically, when the first clamping block 121 rotates to contact the support seat 15, the material transport robot provides the unfilmed screen assembly and places it on the fixture 21, and then the part of the cable that needs to be clamped is placed on the first clamping block 121. Figure 5B shown.

[0173] S400, the telescopic mechanism drives the free end of the limiting rod to extend above the portion between the connection point and a portion of the flexible member and the workpiece to abut against the flexible member.

[0174] Specifically, after the material transport robot places the workpiece on the jig 21, the telescopic mechanism 61 drives the limit rod 62 to extend, so that at least a part of the limit rod 62 is located on the path of synchronous rotation of the first clamp 121 and the second clamp 122, and the free end of the limit rod 62 extends to above the area between the connection point between the flexible member 11 and the workpiece and a part of the flexible member 11, so as to resist the flexible member 11 during the process of synchronous rotation of the first clamp 121 and the second clamp 122 to fold up a part of the flexible member 11, thereby preventing the flexible member 11 from being excessively bent or disconnected from the workpiece.

[0175] S500: The second driving assembly drives the second transmission assembly, so that the second transmission assembly drives the second clamping block to rotate along the third direction R close to the first clamping block, thereby clamping a portion of the cable.

[0176] Specifically, the second driving assembly 32 drives the second rack 142 to move along the first direction A, the second rack 142 drives the second gear 143 to rotate along the third direction R, the second gear 143 drives the second rotating shaft 141 to rotate along the third direction R, and the second rotating shaft 141 drives the second clamping block 122 to rotate along the third direction R close to the first clamping block 121 to clamp a portion of the cable, such as Figure 5C shown.

[0177] It should be noted that, based on the description of this application, the order of step S400 and step S500 can be swapped to achieve the same technical effect.

[0178] S600: The first transmission assembly and the second transmission assembly are synchronously driven to cause the first clamping block and the second clamping block to rotate simultaneously along a fourth direction to fold up a portion of the cable.

[0179] Specifically, in steps S200 and S500, driven by the first drive assembly 31 and the second drive assembly 32, the first rack 132 and the second rack 142 move in the first direction A, respectively abutting against the first spring 161 and the second spring 162, causing the first spring 161 and the second spring 162 to accumulate elastic potential energy. After the external force is removed, the first spring 161 and the second spring 162 utilize the elastic potential energy to drive the first rack 132 and the second rack 142 to move synchronously in the second direction B. The first rack 132 and the second rack 142 respectively drive the first gear 133 and the second gear 143 to rotate in the fourth direction. Consequently, the first gear 133 and the second gear 143 simultaneously drive the first clamp 121 and the second clamp 122 to rotate in the fourth direction, thereby folding a portion of the cable.

[0180] S700: The mobile platform rotates to move the fixture carrying the screen assembly without film attached to the working area of ​​the film attaching mechanism.

[0181] Specifically, after a portion of the cable is folded up, the telescopic mechanism 61 drives the limit rod 62 to retract, so that the limit rod 62 is moved outside the moving path of the jig 21, and the movable platform 20 moves the jig 21 carrying the unfilmed screen assembly to the working area of ​​the film-laminating mechanism 40.

[0182] S800: The film sticking mechanism sticks the film to the corresponding film sticking area.

[0183] Specifically, when the mobile platform 20 moves the jig 21 carrying the unfilmed screen assembly to the working area of ​​the film pasting mechanism 40, the sensor 80 sends a film pasting start signal to the controller, and the controller controls the film pasting mechanism 40 to attach the film to the corresponding film pasting area according to the film pasting start signal.

[0184] S900: The visual inspection mechanism detects whether the workpiece with the film attached meets the film sticking standards.

[0185] Specifically, after the film pasting mechanism 40 adheres the film to the corresponding film pasting area, the mobile stage 20 transfers the workpiece to the visual inspection mechanism 70 , which inspects whether the workpiece with the film pasted meets the film pasting standard.

[0186] In S1000, the material transport robot moves the workpieces that meet the film laminating standards and those that do not meet the film laminating standards to different locations.

[0187] Specifically, the material transport robot moves the workpieces that meet the film laminating standards to the finished product tray, and moves the workpieces that do not meet the film laminating standards to the recycling tray.

[0188] In the film pasting method of the above embodiment, after the bending mechanism 10 folds up a part of the cable, the mobile platform 20 moves the screen assembly without film pasting from the working area of ​​the driving mechanism 30 to the working area of ​​the film pasting mechanism 40, and the film pasting mechanism 40 adheres the film to the corresponding film pasting area of ​​the screen assembly, which can automatically realize the bending of the cable and cooperate with the film pasting mechanism 40 to apply film to the screen assembly, thereby realizing the automation of film pasting and effectively improving the film pasting efficiency.

[0189] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and are not limiting. Those skilled in the art should understand that the technical solution of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application.
