Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0042] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0043] Please refer to Figure 1 to Figure 2 , a film supply device 200 provided for an embodiment of the present utility model, which includes a carrier table 210, a film supply mechanism 220, a film pressing mechanism 230, and a film winding mechanism 240.

[0044] The stage 210 has a conveying path X for conveying the tape 100. One end of the stage 210 along the conveying path X has a winding portion 212 for winding the tape 100. The film supply mechanism 220 and the film pressing mechanism 230 are sequentially arranged on the stage 210 along the conveying path X, and the film pressing mechanism 230 is located between the film supply mechanism 220 and the winding portion 212. Among them, the winding portion 212 can be understood as the end of the stage with a bent arc surface. When the tape 100 bypasses the winding portion 212, the tape 100 moves in other directions, such as downward, and the protective film 120 and the base film 110 tend to separate or are separated.

[0045] The film pressing mechanism 230 includes a limiting member 231 and a film pressing member 232. The limiting member 231 is arranged on the stage 210 along the conveying path X and is close to the conveying path X to limit the edge 211 of the tape 100. The film pressing member 232 is arranged on the limiting member 231, and the film pressing member 232 is used to define a guiding gap for the tape 100 to pass through between it and the stage 210. The film winding mechanism 240 is arranged on the stage 210 to wind up the base film of the tape 100 that has passed through the winding portion 212.

[0046] Among them, the tape 100 includes a base film 110 and a protective film 120, and the protective films 120 are sequentially arranged on the tape 100 at intervals along the length direction of the base film 110.

[0047] In specific applications, the film supply mechanism 220 unwinds the wound tape 100, and the tape 100 is conveyed from the film supply mechanism 220 along the conveying path X to the winding portion 212 and wound around the winding portion 212. Among them, when the tape 100 passes through the winding portion 212, due to the bending of the tape 100 corresponding to the winding portion 212, a certain separation force is generated between the protective film 120 attached to the base film 110 and the base film 110 when passing through the winding portion 212, and there is a certain separation trend between the protective film 120 and the base film 110. In some cases, the protective film 120 and the base film 110 are not completely separated or the sign of their mutual separation cannot be observed, but the adhesion force between them is smaller, which is conducive to the film sticking manipulator 400 to peel the protective film 120 from the base film 110. The film sticking manipulator 400 can include a suction head, and the suction head uses suction to hold the surface of the protective film 120, thereby peeling the protective film 120 from the base film 110. Then, after the base film 110 passes through the winding portion 212, it is conveyed from the lower side of the stage 210 to the film winding mechanism 240, and the film winding mechanism 240 winds up the base film 110.

[0048] As can be seen from the above, by including the limiting member 231 and the film pressing member 232 in the film pressing mechanism 230, the limiting member 231 is arranged on the carrier 210 along the conveying path X, and the limiting member 231 is arranged close to the conveying path X to limit the edge 211 of the strip 100. The film pressing member 232 is arranged on the limiting member 231, and the film pressing member 232 is used to define a guiding gap for the strip 100 to pass between the film pressing member 232 and the carrier 210. The film pressing mechanism 230 can both guide and press the film. When the strip 100 passes through the conveying path X, especially before approaching the winding portion 212, the limiting member 231 effectively limits the edge 211 of the strip 100, so that the strip 100 is not easily deviated. A guiding gap is formed between the film pressing member 232 and the carrier 210, so that the film pressing member 232 can press the strip 100 relatively flat on the carrier 210. The film pressing member 232 has a certain "shaping" effect on the strip 100, making the strip 100 after shaping more flat, which is beneficial to removing the bottom film 110 on the strip 100. For example, the manipulator can accurately grasp the bottom film 110 from the strip 100.

[0049] In some embodiments, referring to Figure 2 and Figure 3 , the film pressing member 232 includes a connected connecting portion 2321 and a film pressing portion 2322. Among them, the connecting portion 2321 is movably arranged on the limiting member 231. For example, a rotational connection, a sliding connection or other movable connection methods can be adopted between the connecting portion 2321 and the limiting member 231. Thus, the film pressing portion 2322 is movably connected to the limiting member 231 by the connecting portion 2321 to move away from or close to the conveying path X of the carrier 210. For example, a rotational connection can be realized between the connecting portion 2321 and the limiting member 231 by using a hinge or a hinge and other connecting members. If the film pressing portion 2322 is selected to move close to the carrier 210, when the film pressing portion 2322 moves to directly above the conveying path X, a guiding gap is defined between the film pressing portion 2322 and the carrier 210 to ensure the flatness of the strip 100 when being conveyed along the conveying path X; if the film pressing portion 2322 is selected to move away from the carrier 210, the restriction on the strip 100 by the film pressing portion 2322 is released.

[0050] In the actual application process, if the strip 100 gets stuck in the guiding gap, the film pressing portion 2322 moves away from the conveying path X by using the connecting portion 2321, and the restriction on the strip 100 by the film pressing portion 2322 is released. The user can conveniently re-pave the strip 100 to solve the problem of the strip 100 getting stuck. Then, the film pressing portion 2322 moves back to directly above the conveying path X by using the connecting portion 2321 to form a guiding gap for restricting the strip 100 with the carrier 210. Of course, when the strip 100 needs to be replaced, the user can adjust the position of the film pressing portion 2322 to facilitate re-laying the strip 100 on the conveying path X.

[0051] In a specific embodiment, with reference to Figure 2 and Figure 3 , the limiting member 231 is fixedly attached to the stage 210 and is located on the side of the conveying path X. The limiting member 231 has a limiting wall facing the conveying path X, and the limiting wall is used to limit the edge 211 of the strip 100. At the same time, the limiting member 231 is provided with a relief opening 2311 on one side of the limiting wall. The relief opening 2311 penetrates the limiting member 231 from one side of the stage 210 to the other side of the stage 210. The relief opening 2311 penetrates the two opposite wall surfaces of the limiting member 231 in the thickness direction of the limiting member 231 and penetrates the limiting wall. The connecting portion 2321 is rotatably disposed in the relief opening 2311 and can move closer to and away from the stage 210. Thus, the film pressing portion 2322 can move closer to the stage 210 through the connecting portion 2321 to form a guiding gap with the stage 210. Of course, the film pressing portion 2322 can also move away from the stage 210 through the connecting portion 2321 to release the restriction on the strip 100.

[0052] It can be understood that through the setting of the relief opening 2311 on the limiting member 231, the relief opening 2311 can make way for the connecting portion 2321 of the film pressing member 232, so that when the film pressing portion 2322 rotates above the conveying path X, a sufficiently small gap can be formed between the film pressing portion 2322 and the stage 210, so as to be able to flatly press the upper surface of the strip 100, so that the strip 100 can be flatly conveyed to the winding portion 212. At the same time, the limiting wall of the limiting member 231 and the film pressing portion 2322 can be located at the position of the conveying path X close to the winding portion 212 at the same time. The limiting member 231 and the film pressing member 232 can cooperate to respectively limit the edge 211 and the upper surface of the strip 100, so as to ensure that the strip 100 is not easily bulged and deviated when entering the winding portion 212.

[0053] Among them, the film pressing portion 2322 extends along the conveying path X, and the length of the film pressing portion 2322 along the conveying path X is greater than or equal to 1 / 2 of the length of the limiting member 231 along the conveying path X. With such a setting, the film pressing portion 2322 has a longer length, so that the film pressing portion 2322 can press the strip 100 along the conveying path X over a longer range to form a longer shaping length, so that the strip film 100 before entering the winding portion 212 is shaped more flatly, so as to minimize the possibility of the strip 100 bulging.

[0054] Furthermore, there are two limiters 231 and two film pressing members 232, and the two limiters 231 are respectively located on both sides of the conveying path X, that is, one limiter 231 is located on one side of the conveying path X, and the other limiter 231 is located on the other side of the conveying path X. A limit channel 2312 is formed between the limit walls of the two limiters 231, and the material belt 100 is laid flat on the limit channel 2312. Among them, the limit wall of one limiter 231 is used to limit one edge 211 of the material belt 100, and the limit wall of the other limiter 231 is used to limit the other edge 211 of the material belt 100, so that the two sides of the material belt 100 can be limited respectively, effectively preventing the material belt 100 from moving left and right. The two film pressing members 232 correspond to a limiting member 231 respectively, that is, one film pressing member 232 is movably connected to one limiting member 231, and the other film pressing member 232 is movably connected to the other limiting member 231. The film pressing parts 2322 of the two limiting members 231 both form guide gaps with the carrier 210, and the two edge parts of the material tape 100 slide in the two guide gaps respectively. It can be seen that the two limiting members 231 cooperate to limit the upper surface of the material tape 100, thereby further ensuring that the material tape 100 can be smoothly transmitted to the winding part 212 along the transmission path X.

[0055] In some embodiments, the two film pressing members 232 are arranged at a relative interval to form a clearance space 2323 between the two, and the clearance space 2323 is used for the middle part of the supply tape 100 to pass through. It can be understood that, through the provision of the clearance space 2323, the user can conveniently act on the opposite side of the two film pressing members 232 through the clearance space 2323, which can not only avoid interference between the two film pressing members 232, but also facilitate the user to apply force to the film pressing member 232 through the clearance space 2323, so that the film pressing member 232 moves away from the carrier 210, so as to facilitate the replacement or leveling of the material tape 100 on the conveying path X.

[0056] It should also be noted that if the wrinkles of the material strip 100 are not obvious, the user can directly level the material strip 100 through the clearance space 2323. For example, the user can use tools or directly use hands to enter the clearance space 2323 to smooth the material strip 100 without controlling the film pressing part 232 to move away from the carrier 210. It can be seen that the clearance space 2323 can facilitate the user to directly level the conveyed material strip 100.

[0057] In some embodiments, reference Figure 1, The film pressing mechanism 230 and the winding part 212 are arranged at intervals along the conveying path to form a grasping space. Specifically, the distance between the film pressing mechanism 230 and the winding part 212 is usually set at about 2 cm. With this setting, the grasping space reserved between the film pressing mechanism 230 and the winding part 212 is large enough to allow the film applying robot 400 to grasp the protective film 120 from a position close to the winding part 212 without interference with the film pressing mechanism 230. At the same time, the distance between the film pressing mechanism 230 and the winding part 212 is not too large. Therefore, the film pressing mechanism 230 can effectively restrict the tape 100 at the position where it is conveyed to the winding part 212 to prevent the tape 100 from being unable to be smoothly conveyed to the winding part 212 when the film applying robot 400 grasps the tape 100.

[0058] To keep the film pressing member 232 buckled on the carrier 210 to restrict the upper surface of the tape 100, in some embodiments, referring to Figure 2 and Figure 3 , the film feeding device 200 includes a magnetic attraction member 233. The magnetic attraction member 233 is arranged on the carrier 210 and magnetically cooperates with the film pressing member 232; alternatively, the magnetic attraction member 233 is arranged on the carrier 210 and magnetically connected to the film pressing member 232. Specifically, when the film pressing member 232 forms a guiding gap with the carrier 210, by using the setting of the magnetic attraction member 233, the magnetic attraction member 233 is used to keep the film pressing member 232 buckled on the carrier 210 to form a guiding gap with the carrier 210. The film pressing member 232 can stably restrict the upper surface of the tape 100, thereby ensuring that the tape 100 can be smoothly conveyed to the winding part 212. If the tape 100 gets stuck in the guiding gap or needs to be replaced, the user can conveniently release the magnetic cooperation to move the film pressing member 232 away from the carrier 210, so as to facilitate the user to conveniently level the tape 100 on the conveying path X or replace the tape 100.

[0059] To enable the tape 100 to smoothly slide into the guiding gap between the carrier 210 and the film pressing member 232, in some embodiments, referring to Figure 1 and Figure 4 , the film feeding device 200 further includes a leveling and rolling mechanism 250. The leveling and rolling mechanism 250 is arranged on the conveying path X and is located between the film feeding mechanism 220 and the film pressing mechanism 230. When the tape 100 is conveyed from the film feeding mechanism 220 to the film pressing mechanism 230, the leveling and rolling mechanism 250 flattens the tape 100, so that the tape 100 can be smoothly conveyed to the guiding gap.

[0060] Specifically, the leveling and rolling mechanism 250 includes a mounting frame 251, a pressing wheel assembly 252, a buffer 253, a first driving member 254, and a first elastic member 255. The mounting frame 251 is arranged in a gantry shape, and the conveying path X passes through the channel on its lower side. The pressing wheel assembly 252 includes a guiding seat 2521 and a rolling wheel 2522. Among them, the guiding seat 2521 is vertically slidably arranged on the top beam of the mounting frame 251, and the rolling wheel 2522 is rotatably arranged at the lower end of the guiding seat 2521 for rolling the strip 100. The buffer 253 is arranged on the top beam of the mounting frame 251, and the buffer head of the buffer 253 faces upward for buffering the downward movement of the guiding seat 2521.

[0061] The first driving member 254 is vertically arranged on the top beam of the mounting frame 251 and faces upward. A guiding column 256 is fixedly connected to the driving shaft of the first driving member 254. A floating seat 257 is vertically slidably arranged on the guiding column 256 and is fixedly connected to the guiding seat 2521. The first elastic member 255 can be a spring. The first elastic member 255 is sleeved on the guiding column 256. The lower end of the first elastic member 255 abuts against the upper end of the floating seat 257, and the upper end of the first elastic member 255 abuts against the upper boss of the guiding column 256. Thus, the guiding seat 2521 abuts between the buffer 253 and the first elastic member 255, and the first driving member 254 acts downward on the guiding seat 2521 through the first elastic member 255.

[0062] In some application scenarios, the buffer 253 and the first elastic member 255 cooperate to limit the guiding seat 2521 to a set height, so that the rolling wheel 2522 is limited to a set height on the carrier 210. During the application stage, when the strip 100 passes under the rolling wheel 2522, the first elastic member 255 provides a stable acting force for the rolling wheel 2522 through the guiding seat 2521, so that the rolling wheel 2522 is stably pressed against the strip 100. Or rather, the rolling wheel 2522 is adaptively pressed against the strip 100 under the action of the first elastic member 255, so that the strip 100 can flow into the guiding gap more smoothly. Among them, during the process of the rolling wheel 2522 pressing the strip 100, the guiding seat 2521 floats up and down, and the buffer 253 has a buffering effect on the up and down floating of the guiding seat 2521.

[0063] In some application scenarios, the first driving member 254 drives the guide post 256 to move downward. The boss at the upper end of the guide post 256 presses down on the first elastic member 255, increasing the initial expansion and contraction amount of the first elastic member 255, so as to be able to provide a sufficiently large elastic force for the rolling wheel 2522 to ensure that the rolling wheel 2522 can effectively flatten the strip 100. In some application scenarios, the first driving member 254 drives the guide post 256 to move upward. The boss at the upper end of the guide post 256 reduces the acting force on the first elastic member 255, and the initial expansion and contraction amount of the first elastic member 255 decreases, so as to be able to provide a suitable elastic force for the guide wheel 355 to avoid the rolling wheel 2522 from pressing down on the strip 100 excessively.

[0064] This application also discloses a film pasting device. Referring to Figure 5 and Figure 6 , it includes the above-mentioned film supply device 200, circular conveying device 300 and film pasting manipulator 400. Among them, the circular conveying device 300 includes a frame 310, a circular conveying mechanism 320 and a plurality of loading fixtures 330. The circular conveying mechanism 320 is arranged in a ring on the frame 310, and each loading fixture 330 is sequentially arranged on the circular conveying mechanism 320. The circular conveying mechanism 320 circulates and conveys the loading fixtures 330 along the circumferential direction, and the loading fixtures 330 sequentially pass through the loading position, the film pasting position and the unloading position.

[0065] Each loading fixture 330 can be horizontally arranged on the conveying part of the circular conveying mechanism 320 or inclinedly arranged on the conveying part of the circular conveying mechanism 320, which is specifically set according to actual needs. The film pasting manipulator 400 is used to grab the protective film 120 from the film supply device 200 to paste the protective film 120 on the workpiece 600 at the film pasting position.

[0066] Specifically, the circular conveying mechanism 320 conveys the loading fixture 330 to the loading position, and the workpiece 600 to be pasted with film is loaded on the loading fixture 330 manually or by a loading manipulator. Then, the circular conveying mechanism 320 conveys the loading fixture 330 to the film pasting position. At this time, the film pasting manipulator 400 grabs the protective film 120 from the film supply device 200 and transports the protective film 120 to the film pasting position to paste the protective film 120 on the workpiece 600. Finally, the circular conveying device 300 conveys the loading fixture 330 to the unloading position, and the workpiece 600 after film pasting is taken out manually or by an unloading manipulator. The emptied loading fixture 330 moves to the loading position again under the conveyance of the circular conveying mechanism 320 to prepare for loading the workpiece 600 next time. As can be seen from the above, during the application process of the film pasting device, the film pasting device automatically completes the material taking of the protective film 120 and the pasting of the protective film 120, thus ensuring the film pasting efficiency of the workpiece 600.

[0067] In some embodiments, referring toFigure 6 , Figure 7 and Figure 8 , the loading fixture 330 includes a fixture body 340, a pressing assembly 350, and a second elastic member 360. The fixture body 340 is horizontally or inclined upwardly disposed on the frame 310 for loading the workpiece 600. The pressing assembly 350 includes a transmission member 351, a first pressing member 352, and a second pressing member 353. Among them, the transmission member 351 is slidably disposed on the back side of the bottom plate portion 341 of the fixture body 340. The first pressing member 352 and the second pressing member 353 are located on two adjacent sides of the bottom plate portion 341 of the fixture body 340 and are in transmission connection with the transmission member 351. At the same time, a first abutting portion 342 is provided on the bottom plate portion 341 of the fixture body 340 and is located at a position opposite to the first pressing member 352. A second abutting portion 343 is also provided on the bottom plate portion 341 of the fixture body 340 and is located at a position opposite to the second pressing member 353. The second elastic member 360 is connected to the fixture body 340 and the transmission member 351 for pressing the first pressing member 352 and the second pressing member 353 against two adjacent sides of the workpiece 600 respectively. Among them, the first pressing member 352 and the first abutting portion 342 are pressed against two sides of the workpiece 600 in the width direction, and the second pressing member 353 and the second abutting portion 343 are pressed against two sides of the workpiece 600 in the length direction.

[0068] In some embodiments, the film pasting device further includes two unlocking devices 500. The circulating conveyor mechanism 320 is used to convey each loading fixture 330 to the loading position and the unloading position. One unlocking device 500 is disposed at the loading position, and the other unlocking device 500 is disposed at the unloading position. The unlocking device 500 is used to push the transmission member 351 towards the fixture body 340 so that the first pressing member 352 and the second pressing member 353 are away from the workpiece placement position.

[0069] In some application scenarios, when the circulating conveyor mechanism 320 conveys the empty loading fixture 330 to the loading position, the unlocking device 500 at the corresponding position pushes the transmission member 351 towards the fixture body 340. The first pressing member 352 moves away from the first abutting portion 342 and the second pressing member 353 moves away from the second abutting portion 343. The loading manipulator can place the workpiece 600 on the bottom plate portion 341 of the fixture body 340. The unlocking device 500 releases the restriction on the transmission member 351. The first pressing member 352 and the second pressing member move towards the workpiece 600 respectively under the action of the second elastic member 360. Thus, the first pressing member 352 and the first abutting portion 342 are pressed against two sides of the workpiece 600 in the width direction, and the second pressing member 353 and the second abutting portion 343 are pressed against two sides of the workpiece 600 in the length direction.

[0070] When the loop conveyor mechanism 320 conveys the loading jig 330 loaded with the workpiece 600 to the unloading position, the unlocking device 500 at the corresponding position pushes the transmission member 351 towards the jig body 340. The first pressing member 352 moves away from the first abutting portion 342, and the second pressing member 353 moves away from the second abutting portion 343. Then the unloading manipulator can grab the workpiece 600 from the loading jig 330.

[0071] In order to enable the transmission member 351 to drive the first pressing member 352 to move in the width direction of the jig body 340 and the second pressing member 353 to move in the length direction of the carrier, in some embodiments, a guide rod 356 is provided at the corner position of the transmission member 351 away from the unlocking device 500. The guide rod 356 is slidably arranged obliquely along the length direction on the mounting seat on the back side of the jig body 340. The length direction of the guide rod 356 is obliquely arranged relative to the length direction and the width direction of the jig body 340. The second elastic member 360 can be a spring. The second elastic member 360 is sleeved on the guide rod 356. One end of the second elastic member 360 abuts against the mounting seat on the back side of the jig body 340, and the other end abuts against the transmission member 351.

[0072] Therefore, when the unlocking device 500 pushes the transmission member 351 towards the jig body 340, the transmission member 351 slides obliquely forward against the elastic force of the second elastic member 360, thereby driving the first pressing member 352 and the second pressing member 353 to move synchronously and obliquely. Among them, during the oblique forward movement of the first pressing member 352, there is a movement displacement in the width direction of the jig body 340 to release the abutting force on the width direction of the workpiece 600. Similarly, during the oblique forward movement of the second pressing member 353, there is a movement displacement in the length direction of the jig body 340 to release the abutting force on the length direction of the workpiece 600.

[0073] In some embodiments, referring to Figure 7 and Figure 8 , the unlocking device 500 includes a second driving member 510 and a pushing member 520. The second driving member 510 is arranged on the mounting frame 251 and faces the jig body 340. The pushing member 520 is connected to the driving part of the second driving member 510. The pushing member 520 is provided with a guiding inclined surface 521 and is located on the movement path of the transmission member 351. At the same time, one end of the transmission member 351 is provided with an extension arm 354. The extension arm 354 extends towards the outside of the loop conveyor mechanism 320. A guiding wheel 355 is arranged at the end of the extension arm 354. The guiding inclined surface 521 is located on the movement path of the guiding wheel 355. Thus, the guiding wheel 355 can roll along the guiding inclined surface 521.

[0074] It can be understood that when the loading fixture 330 moves to the loading position or the unloading position, the guide wheel 355 rolls along the guide inclined surface 521, thereby pushing the extension arm 354 to move in the direction towards the fixture body 340. Therefore, the transmission member 351 drives the first pressing member 352 to move away from the first abutting portion 342, and drives the second pressing member 353 to move away from the second abutting portion 343, so as to facilitate loading the loading fixture 330 or taking out the workpiece 600 on the loading fixture 330. Among them, when it is not necessary to unlock the loading fixture 330, the second driving member 510 drives the pushing member 520 to move in the direction away from the loading fixture 330, and the guide inclined surface 521 disengages from the movement path of the guide wheel 355. Therefore, when at the loading position or the unloading position, the unlocking device 500 does not act on the extension arm 354, and the first pressing member 352 and the second pressing member 353 keep pressing the workpiece 600 under the action of the second elastic member 360.

[0075] The film pasting device provided by the embodiment of the present application includes the above-mentioned film supply device 200, the circulating conveyor device 300 and the film pasting manipulator 400. Among them, the film supply device 200 continuously supplies the protective film to the film pasting manipulator 400, and the circulating conveyor device 300 continuously conveys the workpiece to be pasted with film to the film pasting position and takes away the workpiece with the film pasting completed. Thus, the film pasting manipulator 400 automatically grabs the protective film from the film supply device 200 and pastes the film on the workpiece at the film pasting position, so as to ensure the film pasting efficiency of the workpiece.
