[0082] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0084] In the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0085] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more features.

[0086] Reference Figure 1 The related technology involved in the embodiment of the present application is the adhesive backing 10, which is pasted on the release film 20 during storage. Figure 1 A plurality of adhesive backings 10 are pasted on the release film 20.

[0087] Reference Figure 2 , the adhesive 10 is in the shape of a long strip, Figure 2 The tail of the adhesive 10 shown in the figure has a first bending portion 103, so that the overall profile of the adhesive 10 is L-shaped. The edge of the adhesive 10 also has a plurality of first protrusions 104, so that the adhesive 10 is irregular in shape.

[0088] Reference Figure 3 The adhesive backing 10 includes a protective film 101 and an adhesive layer 102, wherein the adhesive layer 102 is adhered to the protective film 101, and the length of the protective film 101 is greater than the length of the adhesive layer 102. The protective film 101 includes an adhesive section 1011 and a free section 1012, wherein the adhesive section 1011 is adhered to the adhesive layer 102, and the free section 1012 is not adhered to the adhesive layer 102. When the adhesive backing 10 is attached to the release film 20, the adhesive layer 102 is adhered between the protective film 101 and the release film 20, and there is a gap between the free section 1012 of the protective film 101 and the release film 20. The release film 20 can protect the adhesive layer 102 from dust pollution.

[0089] It should be understood that the adhesive backing 10 can be a single-sided adhesive or a double-sided adhesive. When the adhesive backing 10 is a single-sided adhesive, the protective film 101 and the adhesive layer 102 are fixedly connected. When the adhesive backing 10 is a double-sided adhesive, the protective film 101 and the adhesive layer 102 are bonded, so that after the adhesive backing 10 is pasted to the specified position, the protective film 101 can be torn off to make both sides of the adhesive layer 102 have an adhesive effect. When the protective film 101 and the adhesive layer 102 are designed to be separable, the adhesion between the protective film 101 and the adhesive layer 102 is greater than the adhesion between the adhesive layer 102 and the release film 20.

[0090] The specific implementation methods of the present application are further described in detail below with reference to the accompanying drawings.

[0091] Reference Figure 4 The embodiment of the present application discloses a mounting device 1 for automatically mounting adhesive 10. The mounting device 1 includes a peeling mechanism 2 and a correction mechanism 3.

[0092] The peeling mechanism 2 is used to peel the adhesive 10 from the release film 20. When the peeling mechanism 2 is working, it first clamps the free section 1012 of the protective film 101, and then moves toward the adhesive section 1011 away from the free section 1012, so that the protective film 101 drives the adhesive layer 102 to detach from the release film 20, thereby completing the peeling of the adhesive 10 from the release film 20. After the peeling mechanism 2 peels off the adhesive 10, the end of the adhesive section 1011 of the protective film 101 away from the free section 1012 sags due to gravity. The correction mechanism 3 is used to smooth the drooping adhesive 10 clamped on the peeling mechanism 2, so that the adhesive 10 is flatly attached to the peeling mechanism 2, which is convenient for the peeling mechanism 2 to stick the adhesive 10 to the designated position. This application is used as a preferred embodiment. When the correction mechanism 3 smoothes the adhesive 10 that sags due to gravity, the correction mechanism 3 is located below the peeling mechanism 2.

[0093] Reference Figure 5 The peeling mechanism 2 includes a contoured suction head 21 , an abutting portion 22 and a mounting frame 23 , and the contoured suction head 21 and the abutting portion 22 are connected to the mounting frame 23 . Figure 5 The mounting frame 23 shown in FIG. 1 has two profiling suction heads 21 of different shapes, and the profiling suction heads 21 and the adhesive backing 10 (see FIG. Figure 2 The mounting frame 23 is also connected with abutment portions 22 corresponding to each contoured suction head 21.

[0094] Reference Figure 5 and Figure 6 The mounting frame 23 is used to connect the robot 24, and the robot 24 is used to control the movement of the mounting frame 23. Specifically, the robot 24 can be a three-coordinate manipulator, and the robot 24 can control the mounting frame 23 to be parallel or rotated, so that the contour suction head 21 and the abutment portion 22 can move to a specified position.

[0095] Reference Figure 7 , Figure 8 and Fig. 9 The profiling suction head 21 is a vacuum suction head, and the profiling suction head 21 and the adhesive 10 (refer to Figure 2), and since the adhesive backing 10 is in the shape of an elongated strip, the profiling nozzle 21 is in the shape of an elongated strip. The abutment portion 22 is located at one end of the profiling nozzle 21 in the length direction, and the end of the profiling nozzle 21 away from the abutment portion 22 has a second bending portion 212, and the second bending portion 212 corresponds to the shape of the first bending portion 103. Therefore, the overall profile of the profiling nozzle 21 is in an L shape that matches the adhesive backing 10. The profiling nozzle 21 has a plurality of second protrusions 213, and the second protrusions 213 correspond to the shapes of the first protrusions 104, so that the adhesive backing 10 can completely fit the profiling nozzle 21.

[0096] Reference Figure 8 and Fig. 9 At least one suction portion 211 is arranged along the length direction of the profiling suction head 21 on one side thereof, and a plurality of suction holes 2111 formed by the plurality of suction portions 211 are arranged in sequence along the L-shaped profile of the profiling suction head 21. Each suction portion 211 includes a plurality of suction holes 2111, and the plurality of suction holes 2111 in each suction portion 211 are arranged in sequence along the length direction of the profiling suction head 21. Each suction portion 211 is correspondingly connected to a negative pressure switch 2112.

[0097] The suction hole 2111 is used to generate negative pressure to absorb the adhesive 10. Therefore, when the correction mechanism 3 smoothes the adhesive 10, the multi-stage adsorption part 211 sequentially opens the negative pressure to adsorb and fix the adhesive 10 close to the contoured suction head 21, which can reduce the waste of negative pressure energy.

[0098] Reference Figure 7 and Fig. 9 The abutting portion 22 and the contoured suction head 21 can move relative to each other along a first direction, and the first direction is parallel to the direction of the suction hole 2111 .

[0099] Reference Figure 7 and Fig.10 The abutment portion 22 is used to insert the free section 1012 (refer to Figure 3 ) and the release film 20, and between the abutting portion 22 and the contouring suction head 21 for clamping the free section 1012. In this embodiment, the abutting portion 22 is a scraper 221, and the end of the scraper 221 close to the contouring suction head 21 has a blade 2211, and the blade 2211 is relatively thin, so that the blade 2211 can easily shovel into the gap between the free section 1012 of the protective film 101 and the release film 20.

[0100] Reference Figure 5 and Figure 7, the mounting frame 23 is connected with a first translation drive unit 25, a second translation drive unit 26, a third translation drive unit 27 and a visual camera 28. The first translation drive unit 25 is connected to the profiling suction head 21, and the first translation drive unit 25 is used to drive the profiling suction head 21 to move along the first direction. The second translation drive unit 26 is connected to the abutment portion 22, and the second translation drive unit 26 is connected to the third translation drive unit 27. The second translation drive unit 26 can drive the abutment portion 22 to move along the first direction, and the third translation drive unit 27 can drive the second translation drive unit 26 and the abutment portion 22 to move along the second direction, and the second direction is perpendicular to the first direction. In this embodiment, as a preferred embodiment, the first direction is a vertical direction, the second direction is a horizontal direction, and the second direction is parallel to the length direction of the profiling suction head 21. The first translation drive unit 25, the second translation drive unit 26 and the third translation drive unit 27 are all cylinders.

[0101] It should be understood that in other possible embodiments of the present application, the first translation drive unit 25, the second translation drive unit 26 and the third translation drive unit 27 may also be other possible mechanical drive modes such as screw drive and electric push rod.

[0102] The visual camera 28 is used to observe the position of the protective film 101 . Specifically, the visual camera 28 is used to take a picture to locate the position of the free section 1012 of the protective film 101 . Thus, the robot 24 can drive the contoured suction head 21 and the abutment portion 22 to move to the vicinity of the free section 1012 .

[0103] The working principle of the peeling mechanism 2 is as follows: the position of the free section 1012 of the protective film 101 is obtained by taking a photo with the visual camera 28, and then the robot 24 controls the mounting frame 23 to move to the vicinity of the adhesive backing 10, so that the scraper 221 is close to the free section 1012 of the protective film 101, and then the second translation drive unit 26 drives the scraper 221 to move toward the release film 20, so that the scraper 221 is attached to the release film 20, and then the third translation drive unit 27 drives the second translation drive unit 26 and the scraper 221 to move toward the free section 1012 of the protective film 101, so that the blade 2211 of the scraper 221 is shoveled into between the free section 1012 of the protective film 101 and the release film 20. Then the first translation drive unit 25 drives the profiling suction head 21 to move toward the adhesive backing 10 until the profiling suction head 21 and the blade 2211 of the scraper 221 clamp the free section 1012 of the protective film 101. Alternatively, after the blade 2211 of the scraper 221 is scraped into between the free section 1012 of the protective film 101 and the release film 20, the robot 24 is used to control the contouring suction head 21 and the scraper 221 to move synchronously along the first direction, so that the contouring suction head 21 is pressed against the protective film 101. At the same time, due to the limited position of the abutting portion 22, the cylinder piston rod of the second translation drive portion 26 retreats, and finally the contouring suction head 21 and the scraper 221 complete the clamping of the free section 1012.

[0104] After the profiling suction head 21 and the scraper 221 clamp the free section 1012, the robot 24 controls the profiling suction head 21 and the scraper 221 to move toward the protective film 101 away from the free section 1012, so that the backing glue 10 is peeled off from the release film 20, and the adhesive section 1011 and the adhesive layer 102 of the protective film 101 are in a drooping state due to the action of gravity.

[0105] In addition, in order to avoid collision damage between the profiling suction head 21 and the scraper 221 as much as possible during the relative movement, a sliding frame 29 is connected to the first translation driving unit 25, and the first translation driving unit 25 can drive the sliding frame 29 to move along the first direction. Two parallel guide rails 291 are fixed on the sliding frame 29, and the length direction of the guide rails 291 is parallel to the first direction. A fixing member 292 is fixed to the profiling suction head 21 by bolts, and the fixing member 292 is slidably connected to the guide rails 291. A pressure spring 293 is connected between the fixing member 292 and the sliding frame 29, and the expansion and contraction direction of the pressure spring 293 is parallel to the guide rails 291. Therefore, in the process of the profiling suction head 21 and the scraper 221 clamping the free section 1012, the pressure spring 293 plays a buffering role, and avoids the profiling suction head 21 and the scraper 221 from being damaged by rigid collision as much as possible.

[0106] Reference Fig.11 , Fig.12 The correction mechanism 3 includes a support frame 31, a support block 32, a first limit assembly 33 and a second limit assembly 34. The support block 32, the first limit assembly 33 and the second limit assembly 34 are connected to the support frame 31. The support block 32 is used to support the adhesive 10 that sags due to gravity (refer to Figure 4 ). Since the adhesive layer 102 of the adhesive backing 10 faces the support block 32, the support block 32 in this embodiment has a smooth surface, so that the support block 32 and the adhesive layer 102 are not easily adhered. Specifically, the support block 32 can be treated with a non-stick adhesive, such as spraying a non-stick adhesive coating or pasting a non-stick adhesive layer 102.

[0107] When the correction mechanism 3 is used to smooth the sagging adhesive 10, the contouring suction head 21 and the support block 32 can be controlled to move relative to each other along the length direction of the contouring suction head 21. As a preferred embodiment, the robot 24 is used to control the movement of the contouring suction head 21, and the position of the correction mechanism 3 is fixed, so that the contouring suction head 21 and the support block 32 move relative to each other along the length direction of the contouring suction head 21.

[0108] Reference Fig.12 and Fig.13 The first limiting component 33 is used to limit the adhesive 10 from deviating from the contouring suction head 21 in the first deviation correction direction (refer to Figure 4), the second limiting component 34 is used to limit the adhesive backing 10 from deviating from the profiling nozzle 21 in the second correcting direction, and the second correcting direction is perpendicular to the first correcting direction. In this embodiment, when the correction mechanism 3 smoothes the adhesive backing 10 clamped by the peeling mechanism 2, the first correcting direction is the width direction of the profiling nozzle 21, and the second correcting direction is the length direction of the profiling nozzle 21. The second correcting direction is mainly used to correct the second bending portion 212 at the tail of the L-shaped adhesive backing 10. If the adhesive backing 10 is in a straight straight shape, that is, the adhesive backing 10 does not have the first bending portion 103, the correction mechanism 3 does not need to use the second limiting component 34. Therefore, the embodiment of the present application can select the corresponding peeling mechanism 2 and correction mechanism 3 according to the specific shape of the adhesive backing 10.

[0109] Reference Fig.12 and Fig.13 The first position-limiting assembly 33 includes a first roller 331, a second roller 332 and a first sliding driving part 333. The first roller 331 and the second roller 332 are arranged at intervals along the first deviation-correcting direction. The first roller 331 and the second roller 332 are used to accommodate the contoured suction head 21 and the adhesive 10. The support block 32 is located between the first roller 331 and the second roller 332. More specifically, in the first deviation-correcting direction, the support block 32 is located between the first roller 331 and the second roller 332. The support block 32, the first roller 331 and the second roller 332 may be collinear or not.

[0110] Reference Fig.12 and Fig.13 The support block 32 is disposed close to the first roller 331, and the first sliding drive unit 333 is used to drive the second roller 332 to move along the first deviation correction direction. The position of the second roller 332 is adjusted by the first sliding drive unit 333, thereby adjusting the distance between the first roller 331 and the second roller 332, so that the distance between the first roller 331 and the second roller 332 is adapted to the width of the adhesive 10.

[0111] When the peeling mechanism 2 drives the adhesive 10 to pass over the support block 32, the adhesive 10 is restricted by the first roller 331 and the second roller 332, so that the adhesive 10 is not easy to deviate from the profiling suction head 21 from the first deviation correction direction. And when the peeling mechanism 2 drives the adhesive 10 to pass over the support block 32, the distance between the profiling suction head 21 and the support block 32 is small, so that the support block 32 can smooth the adhesive 10 to fit the profiling suction head 21, and the adsorption part 211 of the profiling suction head 21 opens the negative pressure switch 2112, so as to adsorb and fix the attached adhesive 10. As the profiling suction head 21 moves, the negative pressure switches 2112 of the adsorption part 211 close to the support block 32 are opened in sequence, so that the adhesive 10 is gradually adsorbed flatly on the profiling suction head 21.

[0112] The present application is a preferred embodiment. The reason why the support block 32 is arranged close to the first roller 331 is that when the distance between the first roller 331 and the second roller 332 is adjusted, the first roller 331 can remain stationary, and the second roller 332 is pushed by a cylinder for adjustment. Compared with the solution in which the first roller 331 and the second roller 332 are pushed by cylinders respectively, the correction mechanism 3 is simplified and the cost is reduced.

[0113] Reference Fig.12 The second limit assembly 34 includes a third roller 341, a fourth roller 342, a second sliding drive unit 343 and a third sliding drive unit 344. The third roller 341 and the fourth roller 342 are spaced apart in the second deviation correction direction. The third roller 341 and the fourth roller 342 are used to accommodate the contoured suction head 21 and the adhesive backing 10. The second sliding drive unit 343 is used to drive the third roller 341 to slide along the first deviation correction direction. The third sliding drive unit 344 is used to drive the fourth roller 342 to slide along the first deviation correction direction. The second sliding drive unit 343 and the third sliding drive unit 344 are both cylinders. It should be understood that the second sliding drive unit 343 and the third sliding drive unit 344 can also be other mechanical drive methods such as screw drive and electric push rod.

[0114] When the profiling suction head 21 moves above the support block 32, the third roller 341 is in an extended state until the second bend 212 of the profiling suction head 21 contacts the third roller 341, and the profiling suction head 21 stops moving. At this time, the second sliding drive unit 343 drives the third roller 341 to retract, and the third sliding drive unit 344 drives the fourth roller 342 to extend, so that the third roller 341 and the fourth roller 342 correct the adhesive 10 in the second deviation correction direction. Since the first bend 103 at the tail of the adhesive 10 is shorter, the degree of sagging is smaller, and after being corrected by the third roller 341 and the fourth roller 342, it can be adsorbed by the second bend 212 of the profiling suction head 21.

[0115] When the first roller 331, the second roller 332, the third roller 341 and the fourth roller 342 touch the irregular protrusion of the contoured suction head 21, it is inevitable that a collision will occur. For this reason, the correction mechanism 3 further includes a first elastic telescopic member 35, a second elastic telescopic member 36, a third elastic telescopic member 37 and a fourth elastic telescopic member 38. The first elastic telescopic member 35, the second elastic telescopic member 36, the third elastic telescopic member 37 and the fourth elastic telescopic member 38 can be elastic pins or similar spring structures.

[0116] The first elastic stretchable member 35 is fixed on the support frame 31, and the first elastic stretchable member 35 is connected to the first roller 331, and the first elastic stretchable member 35 is used to control the first roller 331 to elastically stretch along the first deviation correction direction. The first sliding drive unit 333 is connected to the second elastic stretchable member 36, and the first sliding drive unit 333 is used to drive the second elastic stretchable member 36 to move along the first deviation correction direction. The second roller 332 is connected to the second elastic stretchable member 36, and the second elastic stretchable member 36 is used to control the second roller 332 to elastically stretch along the first deviation correction direction.

[0117] The second sliding drive unit 343 is connected to the third elastic telescopic member 37, and the second sliding drive unit 343 is used to drive the third elastic telescopic member 37 to move along the first deviation correction direction. The third roller 341 is connected to the third elastic telescopic member 37, and the third elastic telescopic member 37 is used to control the third roller 341 to elastically extend and retract along the second deviation correction direction.

[0118] The third sliding drive unit 344 is connected to the fourth elastic telescopic member 38, and the third sliding drive unit 344 is used to drive the fourth elastic telescopic member 38 to move along the first deviation correction direction. The fourth roller 342 is connected to the fourth elastic telescopic member 38, and the fourth elastic telescopic member 38 is used to control the fourth roller 342 to elastically extend and retract along the second deviation correction direction.

[0119] The implementation principle of the correction mechanism 3 is as follows: the profiling suction head 21 and the scraper 221 of the stripping mechanism 2 clamp one end of the adhesive 10 and pass over the support block 32, and the movement direction of the profiling suction head 21 is parallel to its own length direction. The adhesive 10 is restricted by the first roller 331 and the second roller 332, so that the adhesive 10 is not easy to deviate from the profiling suction head 21 from the first deviation correction direction. The distance between the profiling suction head 21 and the support block 32 is small, so that the support block 32 can smooth the adhesive 10 to fit the profiling suction head 21. As the profiling suction head 21 moves, the negative pressure switch 2112 of the adsorption part 211 close to the support block 32 is opened in turn, so that the adhesive 10 is gradually adsorbed flatly on the bottom of the profiling suction head 21.

[0120] During the movement of the profiling suction head 21 , the third roller 341 is in an extended state, and the second bent portion 212 at the tail of the profiling suction head 21 is bent toward the third roller 341 , so that the profiling suction head 21 stops moving when the second bent portion 212 at the tail of the profiling suction head 21 hits the third roller 341 .

[0121] Then the second sliding drive unit 343 drives the third roller 341 to retract, and the third sliding drive unit 344 drives the fourth roller 342 to extend, so that the third roller 341 and the fourth roller 342 correct the first bending portion 103 at the tail of the adhesive 10, thereby correcting the adhesive 10 in the second correction direction.

[0122] The adhesive 10 on the peeling mechanism 2 is corrected by the first roller 331, the second roller 332, the third roller 341 and the fourth roller 342, and the hanging adhesive 10 is smoothed by the support block 32, so that the vacuum suction force of the contour suction head 21 can stably and evenly adsorb the adhesive 10. After the contour suction head 21 adsorbs the adhesive 10, the scraper 221 is controlled to move away from the contour suction head 21 under the action of the second translation drive unit 26 and the third translation drive unit 27. Finally, the robot 24 is used to control the contour suction head 21 to attach the adhesive 10 to the specified position.

[0123] In the above, the specific implementation of the present application is described with reference to the accompanying drawings. However, those skilled in the art will appreciate that various changes and substitutions may be made to the specific implementation of the present application without departing from the spirit and scope of the present application. These changes and substitutions are all within the scope defined by the present application.
