Detailed implementation mode

[0042] To make the objectives, technical solutions, and advantages of this application more clear, the following will clearly and completely describe the technical solutions of this application in conjunction with specific embodiments of this application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts belong to the scope of protection of this application.

[0043] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this invention belongs. The terms used in the description of this invention in this specification are only for the purpose of describing specific embodiments and are not intended to limit this invention.

[0045] As Figure 4 and Figure 6 shown, an embodiment of an adhesive pasting device of the present invention includes a workbench 2, a loading mechanism 3, a pressing mechanism 4, an adhesive pasting feeding mechanism 5, a wrapping mechanism 6, and a pressure maintaining mechanism 7. The loading mechanism 3 is used to load and fix the product 1. When designing the adhesive paste 8 for the product 1, the adhesive paste 8 has a portion for correspondingly pasting on the first to-be-pasted adhesive area 11, a portion for correspondingly pasting on the second to-be-pasted adhesive area 12, and a portion for correspondingly pasting on the third to-be-pasted adhesive area 13. The portion of the adhesive paste 8 corresponding to the first to-be-pasted adhesive area 11 is collectively referred to as the first portion 81 in the following description, the portion of the adhesive paste 8 corresponding to the second to-be-pasted adhesive area 12 is collectively referred to as the second portion 82 in the following description, and the portion of the adhesive paste 8 corresponding to the third to-be-pasted adhesive area 13 is collectively referred to as the third portion 83 in the following description. The pressing mechanism 4 is used to press the first portion 81 of the adhesive paste 8 onto the first to-be-pasted adhesive area 11. The adhesive pasting feeding mechanism 5 is used to send the adhesive paste 8 to the position of the product 1 carried and fixed on the loading mechanism 3, and the adhesive pasting feeding mechanism 5 is also used to adhere the adhesive paste 8 to the product 1 and make the first portion 81 face and align with the first to-be-pasted adhesive area 11. The wrapping mechanism 6 is used to press the second portion 82 of the adhesive paste 8 onto the second to-be-pasted adhesive area 12, and the wrapping mechanism 6 is also used to press the third portion 83 of the adhesive paste 8 onto the third to-be-pasted adhesive area 13.

[0046] The glue pasting device described in the present invention has the advantages of reducing manual workload, improving automation degree, and improving glue pasting efficiency. When using the glue pasting device described in the present invention to paste the glue sticker 8 on the product 1, the product 1 is carried and fixed by the carrying mechanism 3, and the glue sticker 8 is sent to the position of the product 1 by the glue sticker feeding mechanism 5 and adhered to the product 1, and the first part 81 faces and aligns with the first glue pasting area 11. Then, the first part 81 is pressed and pasted on the first glue pasting area 11 by the pressing and pasting mechanism 4, and the second part 82 is pressed and pasted on the second glue pasting area 12 and the third part 83 is pressed and pasted on the third glue pasting area 13 by the glue wrapping mechanism 6. In this way, the glue pasting of the product 1 can be completed. It can be understood that the glue sticker feeding mechanism 5 is not regarded as an essential element. For example, in some embodiments, the glue sticker 8 is directly sent to the position of the product 1 by manual and adhered to the product 1, and the first part 81 faces and aligns with the first glue pasting area 11.

[0047] The above workbench 2 facilitates the integrated installation of the carrying mechanism 3, the pressing and pasting mechanism 4, the glue wrapping mechanism 6, the glue sticker feeding mechanism 5, and the pressure maintaining mechanism 7, making the glue pasting device of the present invention more integrated, integral, and compact in layout. It can be understood that in other embodiments, the carrying mechanism 3, the pressing and pasting mechanism 4, the glue wrapping mechanism 6, the glue sticker feeding mechanism 5, and the pressure maintaining mechanism 7 can be respectively installed on different brackets or platforms.

[0048] Such as Figure 7As shown, the loading mechanism 3 includes three fixing jigs provided on the workbench 2 and used for loading and fixing the product 1. The three fixing jigs are respectively: the first fixing jig 31 located at the position defined as the pressing and pasting station on the workbench 2, the second fixing jig 32 located at the position defined as the rubber wrapping station on the workbench 2, and the third fixing jig 33 located at the position defined as the pressure maintaining station on the workbench 2. The pressing and pasting mechanism 4 is installed on the workbench 2 corresponding to the pressing and pasting station position, the rubber wrapping mechanism 6 is installed on the workbench 2 corresponding to the rubber wrapping station position, and the pressure maintaining mechanism 7 is provided on the workbench 2 corresponding to the pressure maintaining station position. The first fixing jig 31 is used to load and fix the product 1 during the pressing and pasting process. After the pressing operation of the adhesive patch 8 is completed on the product 1, the product 1 is moved and loaded and fixed on the second fixing jig 32. The second fixing jig 32 is used to load and fix the product 1 during the rubber wrapping process. After the rubber wrapping operation of the adhesive patch 8 is completed on the product 1, the product 1 is moved and loaded on the third fixing jig 33. The third fixing jig 33 is used to load the product 1 during the pressure maintaining process. After the pressure maintaining operation is completed, the product 1 can be removed from the third fixing jig 33 to complete the adhesive pasting operation. When moving the product 1 from the first fixing jig 31 to the second fixing jig 32 and from the second fixing jig 32 to the third fixing jig 33, it can be completed by a manipulator or manually. It can be understood that the loading mechanism 3 is not limited to the above-described structural form. For example, in some embodiments, the loading mechanism 3 includes a moving jig provided on the workbench 2 and a jig driving mechanism provided on the workbench 2 and used to drive the moving jig to move between the pressing and pasting station, the rubber wrapping station, and the pressure maintaining station. The product 1 is loaded and fixed on the moving jig. The jig driving mechanism can be a cylinder or a linear module. With this structure, the product 1 is moved between the pressing and pasting station, the rubber wrapping station, and the pressure maintaining station by means of the moving jig, thereby driving the product 1 to move between the pressing and pasting station, the rubber wrapping station, and the pressure maintaining station. In this embodiment, when the product 1 is loaded on the first fixing jig 31, the second fixing jig 32, and the third fixing jig 33, the first adhesive patch area 11 faces downward, the second adhesive patch area 12 faces upward, and the third adhesive patch area 13 faces a horizontal direction.

[0049] As Figure 8As shown, the first fixing fixture 31 includes a first fixture body 311 for carrying the product 1, a first positioning block 312 and / or a first positioning pin 313 provided on the first fixture body 311 for positioning the product 1, a first lifting block 314 provided above the first fixture body 311 corresponding to the carrying position of the product 1, and a first lifting drive unit 315 connected to the workbench 2 through a connecting frame and used to drive the first lifting block 314 to lift so that the first lifting block 314 releases from the product 1 or presses the product 1 against the first fixture body 311. The first lifting drive unit 315 can be a cylinder, a hydraulic cylinder or a push rod motor. In other embodiments, the first lifting drive unit 315 can also be installed on the first fixture body 311. The first fixture body 311 supports the product 1, the first positioning block 312 and / or the first positioning pin 313 position the product 1 on the first fixture body 311, and the first lifting drive unit 315 drives the first lifting block 314 to press the product 1 against the first fixture body 311, thereby realizing the carrying and fixing of the product 1 by the first fixing fixture 31. It should be noted that when the first fixture body 311 carries the product 1, the first adhesive application area 11 cannot be blocked, and when the first lifting block 314 presses the product 1, the second adhesive application area 12 cannot be blocked.

[0050] As Figure 9As shown, the second fixing fixture 32 includes a second fixture body 321 for carrying the product 1, a second positioning block 322 and / or a second positioning pin 323 provided on the second fixture body 321 for positioning the product 1, a second lifting block 324 provided above the second fixture body 321 corresponding to the carrying position of the product 1, and a second lifting drive unit 325 provided on the second fixture body 321 for driving the second lifting block 324 to lift and lower so that the second lifting block 324 releases from the product 1 or presses the product 1 against the second fixture body 321. The second lifting drive unit 325 can be a cylinder, a hydraulic cylinder or a push rod motor. In other embodiments, the second lifting drive unit 325 can also be mounted on the workbench 2 through a connecting frame. The second fixture body 321 supports the product 1, the second positioning block 322 and / or the second positioning pin 323 position the product 1 on the second fixture body 321, and the second lifting drive unit 325 drives the second lifting block 324 to press the product 1 against the second fixture body 321, thereby realizing the carrying and fixing of the product 1 by the second fixing fixture 32. It should be noted that when the second fixture body 321 carries the product 1, the first adhesive application area 11 cannot be blocked, and when the second lifting block 324 presses the product 1, the second adhesive application area 12 cannot be blocked.

[0051] As Figure 10 shown, the third fixing fixture 33 includes a third fixture body 331 for carrying the product 1 and a third positioning block 332 and / or a third positioning pin 333 provided on the first fixture body 311 for positioning the product 1. The third fixture body 331 supports the product 1, and the third positioning block 332 and / or the third positioning pin 333 position the product 1 on the third fixture body 331. The pressure maintaining mechanism 7 itself can fix the product 1, so during the pressure maintaining process, the carrying mechanism 3 does not need to fix the product 1, that is, the third fixing fixture 33 does not need to be additionally provided with a structure for pressing the product 1 against the third fixture body 331. Of course, in other embodiments, the third fixing fixture 33 can also include a structure for pressing the product 1 against the third fixture body 331 to make the product 1 more stably supported on the third fixture body 331.

[0052] As Figure 11As shown, the pressing mechanism 4 includes a pressing member 41 and a pressing driving mechanism 42. The pressing driving mechanism 42 is configured to drive the pressing member 41 to move towards the first adhesive area 11 to press the first part 81 onto the first adhesive area 11. The pressing driving mechanism 42 is further configured to drive the pressing member 41 to move away from the first adhesive area 11 and disengage from the first adhesive area 11. The pressing member 41 includes a pressing block 411 and a pressing surface 412. The pressing block 411 is disposed at the output end of the pressing driving mechanism 42. The pressing surface 412 is formed on the side of the pressing block 411 facing the first adhesive area 11. The pressing surface 412 is adapted to the first adhesive area. The pressing driving mechanism 42 drives the pressing block 411 to move towards the first adhesive area 11, and the pressing surface 412 presses the first part 81 on the first adhesive area 11. Since the pressing surface 412 is adapted to the first adhesive area 11, the pressing surface 412 can quickly and tightly press the part of the adhesive patch 8 corresponding to the first adhesive area 11 onto the first adhesive area 11.

[0053] The pressing and pasting driving mechanism 42 includes a first pressing and pasting driving unit 421 for driving the pressing block 411 to move up and down, and a second pressing and pasting driving unit 422 disposed on the workbench 2 and used for driving the first pressing and pasting driving unit 421 to horizontally move towards or away from the directly below of the first adhesive pasting area 11. Both the first pressing and pasting driving unit 421 and the second pressing and pasting driving unit 422 can be air cylinders, hydraulic cylinders, push rod motors or linear modules. Before pressing the first part 81 onto the first adhesive pasting area 11, the product 1 is carried and fixed on the first fixture body 311. The second pressing and pasting driving unit 422 can drive the first pressing and pasting driving unit 421 to horizontally move so as to drive the pressing block 411 to horizontally move to the directly below of the first adhesive pasting area 11. Then, the first pressing and pasting driving unit 421 drives the pressing block 411 to rise, that is, to move the pressing block 411 towards the first adhesive pasting area 11, so that the first part 81 can be pressed onto the first adhesive pasting area 11. After pressing the part of the adhesive sticker 8 corresponding to the first adhesive pasting area 11 onto the first adhesive pasting area 11, the first pressing and pasting driving unit 421 drives the pressing block 411 to descend, that is, to move the pressing block 411 away from the first adhesive pasting area 11, so that the pressing block 411 is separated from the first part 81. Then, the second pressing and pasting driving unit 422 drives the first pressing and pasting driving unit 421 to horizontally move and move away from the directly below of the first adhesive pasting area 11, so as to create enough space for the adhesive sticker feeding mechanism 5 to paste the adhesive sticker 8 on the product 1. The second pressing and pasting driving unit 422 is not regarded as an essential element. For example, in some embodiments, the pressing and pasting driving mechanism 42 can only include the first pressing and pasting driving unit 421 disposed on the workbench 2 and located directly below the first adhesive pasting area 11. The first pressing and pasting driving unit 421 is used for driving the pressing block 411 to rise so as to press the part of the adhesive sticker 8 corresponding to the first adhesive pasting area 11 onto the first adhesive pasting area 11. The first pressing and pasting driving unit 421 is also used for driving the pressing block 411 to descend and separate from the first part 81. Only by reasonably setting the limit position of the first pressing and pasting driving unit 421 for driving the pressing block 411 to descend, that is, making the distance between the limit position of the first pressing and pasting driving unit 421 for driving the pressing block 411 to descend and the first adhesive pasting area 11 large enough, there can be enough space between the limit position and the first adhesive pasting area 11 for the adhesive sticker feeding mechanism 5 to paste the adhesive sticker 8 on the product 1.

[0054] Such as Figure 12As shown, the sticker feeding mechanism 5 includes an anti-sticking platform 51, a grasping mechanism 52, a feeding driving mechanism 53, a grasping and positioning mechanism 54, and a sticker discharging mechanism 55. The anti-sticking platform 51 has a bearing surface for upwardly bearing the sticker 8, and an anti-sticking coating is sprayed or an anti-sticking film is pasted on the bearing surface, so that the sticker 8 cannot be pasted on the bearing surface. The grasping mechanism 52 is used to grasp the sticker 8 borne on the bearing surface. The feeding driving mechanism 53 is used to drive the grasping mechanism 52 to move to the position of the bearing surface so that the grasping mechanism can grasp the sticker 8 borne on the bearing surface. The feeding driving mechanism 53 is also used to move the grasping mechanism 52 to the position of the product 1 after grasping the sticker 8 and adhere the sticker 8 to the product 1 so that the first part 81 faces and aligns with the first sticker-attaching area 11. Specifically, the grasping mechanism 52 pastes the sticker 8 on the product 1 fixed on the first jig body 311. The sticker discharging mechanism 55 is used to convey the sticker 8 to the bearing surface. With this structure, the sticker 8 can be automatically adhered to the product 1 fixed on the first jig body 311, without manually pasting the sticker 8 on the product 1, which is more convenient to use. It can be understood that the bearing seat, the grasping and positioning mechanism 54, and the sticker discharging mechanism 55 are not regarded as necessary elements. For example, in some embodiments, the sticker 8 can be directly placed at the grasping position of the grasping mechanism 52 by hand.

[0055] As Figure 13 As shown, the grasping mechanism 52 includes a grasping part 521 and a rotation driving mechanism 522. The grasping part 521 is arranged on the output shaft of the rotation driving mechanism 522. The grasping part 521 is used to grasp the sticker 8 borne on the bearing surface. The rotation driving mechanism 522 is arranged at the output end of the feeding driving mechanism 53. The rotation driving mechanism 522 is used to drive the grasping part 521 to rotate so that the grasping surface of the grasping part 521 vertically faces the bearing surface of the anti-sticking platform 51. The rotation driving mechanism 522 is also used to drive the grasping part 521 to rotate so that the grasping surface faces the first sticker-attaching area 11. With this structure, the orientation of the grasping part 521 can be flexibly switched, which is convenient to adhere the grasped sticker 8 to the first sticker-attaching area 11 after grasping the sticker 8 on the bearing surface.

[0056] The grasping part 521 includes a grasping block 5211, adsorption holes 5222, and a vacuum pumping device (not shown in the figure). The grasping block 5211 is arranged at the output end of the rotation driving mechanism 522. The adsorption holes 5222 are formed in the grasping block 5211 and communicate with the grasping surface located on the grasping block 5211. The vacuum pumping device is communicated with the adsorption holes 5222. The vacuum pumping device can be a vacuum pump. When the grasping surface abuts against the adhesive patch 8, the gas in the adsorption holes 5222 is extracted by the vacuum pumping device, and the adsorption holes 5222 can adsorb the adhesive patch 8, so that the grasping of the adhesive patch 8 by the grasping part 521 can be realized in this way.

[0057] The rotation driving mechanism 522 includes a first rotation driving unit 5221 and a second rotation driving unit 5222. Both the first rotation driving unit 5221 and the second rotation driving unit 5222 can be servo motors or stepper motors. The first rotation driving unit 5221 is disposed at the output end of the loading driving mechanism 53. The output shaft of the first rotation driving unit 5221 is parallel to the bearing surface. The second rotation driving unit 5222 is disposed on the output shaft of the first rotation driving unit 5221. The output shaft of the second rotation driving unit 5222 is perpendicular to the output shaft of the first rotation driving unit 5221. The grasping portion 521 is disposed on the output shaft of the second rotation driving unit 5222. Specifically, the grasping block 5211 is disposed on the output shaft of the second rotation driving unit 5222, and the grasping surface is perpendicular to the output shaft of the second rotation driving unit 5222. The loading driving mechanism 53 can drive the first rotation driving unit 5221 to move. The first rotation driving unit 5221 can drive the second rotation driving unit 5222 to rotate. The grasping block 5211 can move with the second rotation driving unit 5222 and rotate around the axis of the first rotation driving unit 5221, so that the grasping surface is axially aligned with the sticker 8 located on the bearing surface in the axial direction of the output shaft of the second rotation driving unit 5222. Driving the grasping block 5211 to rotate by the second rotation driving unit 5222 can make the grasping surface on the grasping block 5211 face the sticker 8 in the circumferential direction of the output shaft of the second rotation driving unit 5222. In this way, the grasping surface can be aligned with the sticker 8, that is, the grasping accuracy of the grasping portion 521 for the sticker 8 can be ensured, and further the pasting accuracy of the sticker 8 on the product 1 can be improved. Before adhering the sticker 8 to the product 1, the first rotation driving unit 5221 drives the second rotation driving unit 5222 to rotate so that the grasping surface faces upward. Then the loading driving mechanism 53 drives the first rotation driving unit 5221 to move and drives the grasping surface to move to directly below the first sticker-applying area 11 of the product 1 carried on the first fixture body 311, and aligns the first portion 81 with the first sticker-applying area 11 in the vertical direction. Then the loading driving mechanism 53 drives the first rotation driving unit 5221 to rise. The bearing surface rises with the first rotation driving unit 5221 and adheres to the product 1. At this time, the first portion 81 still remains in a state of facing and aligning with the first sticker-applying area 11. In this way, the sticker loading mechanism 5 can adhere the sticker 8 to the product 1 and make the portion of the sticker 8 corresponding to the first sticker-applying area 11 face and align with the first sticker-applying area 11.

[0058] Such as Figure 14As shown in the figure, the loading driving mechanism 53 includes a first loading driving unit 531, a second loading driving unit 532 and a third loading driving unit 533. The first loading driving unit 531, the second loading driving unit 532 and the third loading driving unit 533 can all be cylinders, hydraulic cylinders, push rod motors or linear modules. The grasping mechanism 52 is arranged at the output end of the first loading driving unit 531. Specifically, the first rotation driving unit 5221 is arranged at the output end of the first loading driving unit 531. The first loading driving unit 531 is used to drive the first rotation driving unit 5221 to move in the first direction. The first loading driving unit 531 is arranged at the output end of the second loading driving unit 532. The second loading driving unit 532 is used to drive the first loading driving unit 531 to move in the second direction perpendicular to the first direction. The third loading driving unit 533 is arranged on the workbench 2. The second loading driving unit 532 is arranged at the output end of the third loading driving unit 533. The third loading driving unit 533 is used to drive the second loading driving unit 532 to move in the third direction perpendicular to the first direction and the second direction. With this structure, the loading driving mechanism 53 can drive the first rotation driving unit 5221 to perform three-dimensional movement, which is convenient for moving the grasping block 5211 to the position of the bearing surface to grasp the sticker 8 carried on the bearing surface, and is also convenient for moving the grasping block 5211 to the lower part of the first sticker-applying area 11 of the product 1 carried and fixed on the first fixture body 311 after the grasping block 5211 grasps the sticker 8.

[0059] As Figure 15 shown in the figure, the grasping and positioning mechanism 54 includes a processing unit, a CCD 541 and a support frame 542. The support frame 542 is arranged on the workbench 2. The CCD 541 is arranged on the support frame 542. The CCD 541 is electrically connected to the processing unit. The CCD 541 is located directly above the bearing surface. The CCD 541 is used to take pictures and collect the position image of the sticker 8 on the bearing surface. The processing unit is used to control the loading driving mechanism 53 to drive the first rotation driving unit 5221 to move, control the first rotation driving unit 5221 to drive the second rotation driving unit 5222 to rotate and control the second rotation driving unit 5222 to drive the grasping part 521 to rotate according to the position image collected by the CCD 541, so that the grasping surface is aligned with the sticker 8. By setting the grasping and positioning mechanism 54, it is convenient to align the grasping part 521 with the sticker 8, and the grasping accuracy of the grasping block 5211 for the sticker 8 can be ensured.

[0060] As Figure 5 andFigure 16 As shown, the sticker discharging mechanism 55 includes a discharging mounting part 551, a conveying mechanism 552 and a stripping part 553. The discharging mounting part 551 is arranged on the workbench 2. The conveying mechanism 552 and the stripping part 553 are both arranged on the discharging mounting part 551. The adhesive surface of the sticker 8 faces downward and is sequentially pasted on the strip-shaped bottom film 9 along the length direction of the strip-shaped bottom film 9. The conveying mechanism 552 is used to convey the strip-shaped bottom film 9 to convey the sticker 8 to the position of the bearing surface. The stripping part 553 is used to peel the sticker 8 conveyed to the position of the bearing surface from the strip-shaped bottom film 9 onto the bearing surface. With this structure, the sticker discharging mechanism 55 can convey the sticker 8 onto the bearing surface. The adhesive surface of the sticker 8 faces downward. After the sticker 8 is peeled off from the strip-shaped bottom film 9, the adhesive surface of the sticker 8 can also face downward and be supported on the bearing surface. In this embodiment, the discharging mounting part 551 is defined as a discharging mounting plate arranged on the workbench 2. It can be understood that the discharging mounting part 551 is not limited to being a discharging mounting plate. For example, in some embodiments, the discharging mounting part 551 can also be a discharging mounting frame.

[0061] As Figure 16 shown, the conveying mechanism 552 includes a first reel 5521, a second reel 5522, a conveying driving unit (not shown in the figure) and a plurality of glue feeding rollers 5523. The first reel 5521, the second reel 5522 and the plurality of glue feeding rollers 5523 are all arranged on the discharging mounting part 551. One end of the strip-shaped bottom film 9 is wound on the first reel 5521. The other end of the strip-shaped bottom film 9 passes through the stripping part 553 and is wound on the second reel 5522. The conveying driving unit can be a motor or a rotary cylinder. The conveying driving unit drives the second reel 5522 to rotate and wind the strip-shaped bottom film 9. When the second reel 5522 winds the strip-shaped bottom film 9, the part of the strip-shaped bottom film 9 wound on the first reel 5521 is pulled and sent out from the first reel 5521. The part of the strip-shaped bottom film 9 loosened from the first reel 5521 passes through the stripping part 553 and is wound on the second reel 5522. In this way, the conveying of the strip-shaped bottom film 9 can be realized. Among the plurality of glue feeding rollers 5523, a part of the glue feeding rollers 5523 are located on the part of the conveying path of the strip-shaped bottom film 9 between the first reel 5521 and the stripping part 553, and another part of the glue feeding rollers 5523 are located on the part of the conveying path between the second reel 5522 and the stripping part 553. The glue feeding rollers 5523 play a role in guiding the conveying of the strip-shaped bottom film 9.

[0062] As Figure 6 and​Figure 17 As shown, the stripping part 553 includes a stripping plate 5531 and a pressing plate 5532. The stripping plate 5531 is disposed at a position corresponding to the bearing surface on the discharging mounting part 551. The pressing plate 5532 is disposed above the stripping plate 5531. The gap 5533 between the pressing plate 5532 and the stripping plate 5531 is adapted to the sum of the thicknesses of the strip-shaped bottom film 9 and the adhesive sticker 8. One end of the gap 5533 facing away from the bearing seat is defined as the glue inlet end, and one end of the gap 5533 close to the bearing seat is defined as the glue outlet end. The conveying direction of the strip-shaped bottom film 9 by the conveying mechanism 552 turns downward at the glue outlet end position, that is, the conveying direction of the strip-shaped bottom film 9 by the conveying mechanism 552 includes a first conveying direction from the glue inlet end to the glue outlet end and a second conveying direction that turns downward from the glue outlet end position. When the second reel 5522 winds up the strip-shaped bottom film 9, the strip-shaped bottom film 9 released from the first reel 5521 passes through the gap 5533 and moves toward the glue outlet end in the gap 5533. The part of the strip-shaped bottom film 9 conveyed to the glue outlet end position turns downward for conveying. When the adhesive sticker 8 moves to the glue outlet end position along with the strip-shaped bottom film 9, the pressing plate 5532 presses the part of the adhesive sticker 8 located in the gap 5533. The part of the adhesive sticker 8 passing through the glue outlet end does not turn along with the turning of the strip-shaped bottom film 9. The part of the strip-shaped bottom film 9 that turns at the glue outlet end position is torn off from the adhesive sticker 8. The adhesive sticker 8 moves in the direction of the bearing surface along the orientation of the glue outlet end and drops onto the bearing surface. In this way, the stripping operation can be completed on the strip-shaped bottom film 9, that is, the adhesive sticker 8 can be conveyed and peeled off onto the bearing surface. The lower side of the adhesive sticker 8 is an adhesive surface. Specifically, the side of the adhesive sticker 8 adhered to the upper side of the strip-shaped bottom film 9 is the adhesive surface. A support sheet 10 is adhered to the upper side of the adhesive sticker 8. The support sheet 10 can be torn off from the adhesive sticker 8. The adhesive force of the support sheet 10 on the adhesive sticker 8 is greater than the adhesive force of the adhesive sticker 8 on the strip-shaped bottom film 9, so that when the bottom film is peeled off from the adhesive sticker 8, the adhesive sticker 8 will not be peeled off from the support sheet 10. The support sheet 10 is used to support the adhesive sticker 8. The adhesive sticker 8 and the support sheet 10 adhered together have greater stiffness. When the bottom film turns at the glue outlet end position, the possibility that the adhesive sticker 8 located at the glue outlet end position bends and turns along with the bending and turning of the strip-shaped bottom film 9 can be reduced, making it easier for the strip-shaped bottom film 9 to be peeled off from the adhesive sticker 8. It can be understood that in other embodiments, the support sheet 10 may not be provided on the adhesive sticker 8, as long as the adhesive sticker 8 itself has sufficient bending stiffness.

[0063] As Figure 18As shown, the junction between the third adhesive application area 13 and the first adhesive application area 11 is defined as the starting position of adhesive wrapping, and the end of the second adhesive application area 12 away from the third adhesive application area 13 is defined as the ending position of adhesive wrapping. The adhesive wrapping mechanism 6 includes an adhesive wrapping part 61, an adhesive wrapping driving mechanism 62, and a tearing part 63. The adhesive wrapping driving mechanism 62 is used to drive the adhesive wrapping part 61 to scrape and press the adhesive sticker 8 from the starting position of adhesive wrapping through the third adhesive application area 13 and the second adhesive application area 12 to the ending position of adhesive wrapping, so that the third part 83 is pasted on the third adhesive application area 13, and the second part 82 is pasted on the second adhesive application area 12. By scraping and pressing, the third part 83 of the adhesive sticker 8 carried and fixed on the second fixture body 321 is pasted on the third adhesive application area 13, and the second part 82 is pasted on the second adhesive application area 12, which can reduce the air bubbles between the adhesive sticker and the product 1 and improve the quality of adhesive application.

[0064] As Figure 19 As shown, the adhesive wrapping part 61 includes a scraping block mounting seat 611, a scraping block 612, a holding part 613, an elastic part 614, and a guiding part 615. The scraping block mounting seat 611 is arranged at the output end of the adhesive wrapping driving mechanism 62. The scraping block 612 and the holding part 613 are both arranged on the scraping block mounting seat 611. The side of the scraping block 612 facing away from the elastic part 614 is a guiding surface 6121 that slopes away from the product 1 from bottom to top. The angle between the guiding surface 6121 and the lower side surface of the scraping block 612 forms a scraping rib 6122. The holding part 613 is located on the side of the scraping block 612 facing away from the product 1. The holding part 613 is a scraping block 612 holding plate arranged on the scraping block mounting seat 611 and located on the side of the scraping block 612 facing away from the product 1. In other embodiments, the holding part 613 can also be a holding column arranged on the scraping block mounting seat 611. The elastic part 614 can be a spring or an elastic rubber section. The elastic part 614 is located between the holding part 613 and the scraping block 612. The elastic part 614 is used to push and press the scraping block 612 towards the product 1. The guiding part 615 includes a sliding rail 6151 arranged on the scraping block mounting seat 611 and a sliding groove 6152 arranged on the scraping block 612 and slidingly matched with the sliding rail 6151. Through the cooperation of the sliding groove 6152 and the sliding rail 6151, the guiding part 615 can guide the movement of the scraping block 612 along the pushing direction of the elastic part 614, so that the movement of the scraping block 612 along the pushing direction of the elastic part 614 is more stable. It can be understood that the guiding part 615 is not regarded as an essential element.

[0065] The rubber wrapping driving mechanism 62 is used to drive the rubber scraping block mounting seat 611 to move so that the guiding surface 6121 abuts against the rubber wrapping starting position upward. The rubber wrapping driving mechanism 62 is also used to drive the rubber scraping block mounting seat 611 to move upward after the guiding surface 6121 abuts against the rubber wrapping starting position. Since the guiding surface 6121 abutting against the rubber wrapping starting position is inclined away from the product 1 from bottom to top, during the process of the rubber wrapping driving mechanism 62 driving the rubber scraping block mounting seat 611 to move upward, under the combined action of the guiding surface 6121 and the rubber scraping starting position, the rubber scraping block 612 will move away from the product 1 carried and fixed on the second fixture body 321 and compress the elastic member 614. After the rubber scraping block 612 moves upward a certain distance, under the pushing action of the elastic member 614, the rubber scraping rib 6122 can press the third part 83 on the third adhesive waiting area 13 and move upward along with the rubber scraping block 612. The rubber scraping block 612 can scrape and paste the third part 83 on the third adhesive waiting area 13 from bottom to top, and can also scrape and paste the second part 82 on the second adhesive waiting area 12 from bottom to top. The elastic member 614 can provide pressure to the adhesive sticker 8 when scraping the adhesive sticker 8, so that the adhesive sticker 8 can be scraped and pasted on the product 1. The structure for scraping and pasting the adhesive sticker 8 on the product 1 in the adhesive pasting device of the present invention is simple and ingenious, that is, the structure of the rubber wrapping mechanism 6 is simple and ingenious, and there is no need to set a complex control program to control the rubber scraping path of the rubber scraping block 612.

[0066] Such as Figure 18As shown, the rubber coating driving mechanism 62 includes a first rubber coating driving mechanism unit 621 and a second rubber coating driving mechanism unit 622. Both the first rubber coating driving mechanism unit 621 and the second rubber coating driving mechanism unit 622 can be cylinders, hydraulic cylinders, push rod motors or linear modules. The rubber scraping block mounting seat 611 is arranged at the output end of the first rubber coating driving mechanism unit 621. The first rubber coating driving mechanism unit 621 is used to drive the rubber scraping block mounting seat 611 to move up and down. The second rubber coating driving mechanism unit 622 is arranged on the workbench 2, and the first rubber coating driving mechanism unit 621 is arranged at the output end of the second rubber coating driving mechanism unit 622. The second rubber coating driving mechanism unit 622 drives the first rubber coating driving mechanism unit 621 to move towards or away from the product 1, so that the position of the guiding surface 6121 on the rubber scraping block 612 moves to below the rubber coating starting position. When the first rubber coating driving mechanism unit 621 drives the rubber scraping block mounting seat 611 to move upward, the guiding surface 6121 can abut against the rubber coating starting position upward. It can be understood that the second rubber coating driving mechanism unit 622 is not regarded as an essential element. For example, in some embodiments, the first rubber coating driving mechanism unit 621 can be directly arranged on the workbench 2, as long as it is ensured that the guiding surface 6121 on the guiding block mounted on the first rubber coating driving mechanism unit 621 is directly below the rubber coating starting position.

[0067] As Figure 6 shown, the support sheet 10 includes a bearing part 101 and a protruding part 102. The bearing part 101 is used for pasting on the adhesive sticker 8, and the protruding part 102 extends out from the edge of the bearing part 101. The tearing part 63 is used for clamping the protruding part 102 and tearing the support sheet 10 from the adhesive sticker 8 pasted on the product 1. By tearing the support sheet 10 from the adhesive sticker 8 through the tearing part 63, there is no need to manually tear the support sheet 10 from the adhesive sticker 8, which can save the manual workload.

[0068] As Figure 18As shown, the tearing part 63 includes a clamping cylinder 631 whose clamping end faces the protruding part 102 of the support sheet 10 pasted on the sticker on the product 1, and a tearing driving unit 632 for driving the clamping cylinder 631 to move towards or away from the protruding part 102. The tearing driving unit 632 can be a cylinder, a hydraulic cylinder, a push rod motor or a linear module. In this embodiment, the tearing driving unit 632 is arranged on the sticker scraping block mounting seat 611. By driving the clamping cylinder 631 to move towards the protruding part 102 through the tearing driving unit 632, when the clamping end of the clamping cylinder 631 moves to the position of the protruding part 102, the clamping end of the clamping cylinder 631 clamps the protruding part 102. Then, the tearing driving unit 632 drives the clamping cylinder 631 to move away from the product 1 carried and fixed on the second fixture body 321, and the tearing part 63 can tear the support sheet 10 from the sticker 8 pasted on the product 1. It can be understood that the tearing driving unit 632 is not limited to being arranged on the sticker scraping block mounting seat 611. For example, in some embodiments, the tearing driving unit 632 can also be installed on the workbench 2 through a connecting frame.

[0069] The pressure maintaining mechanism 7 is used to press the first part 81 against the first adhesive application area 11 for pressure maintaining, and the pressure maintaining mechanism 7 is also used to press the second part 82 against the second adhesive application area 12 for pressure maintaining. After the first part 81 is pressed against the first adhesive application area 11 and the second part 82 is pressed against the second adhesive application area 12, the product 1 is moved and carried on the third fixture body 331. By pressing the first part 81 against the first adhesive application area 11 through the pressure maintaining mechanism 7 and keeping it pressed for a period of time, and by pressing the second part 82 against the second adhesive application area 12 through the pressure maintaining mechanism 7 and keeping it pressed for a period of time, the sticking strength of the sticker 8 pasted on the product 1 can be improved, making the sticker 8 not easy to warp and fall off on the product 1, and the sticking quality of the sticker 8 on the product 1 can be improved.

[0070] As Figure 20 and Figure 21As shown, the pressure-holding mechanism 7 includes a first pressure-holding block 71, a second pressure-holding block 72 facing the first pressure-holding block 71, and a pressure-holding driving mechanism 73 for driving the first pressure-holding block 71 and the second pressure-holding block 72 to move towards each other and respectively press the first adhesive-applying area 11 and the second adhesive-applying area 12; the side of the first pressure-holding block 71 for pressing the first adhesive-applying area 11 is defined as a first pressure-holding surface 711 adapted to the first adhesive-applying area, and the side of the second pressure-holding block 72 for pressing the second adhesive-applying area 12 is defined as a second pressure-holding surface 721 adapted to the second adhesive-applying area 12. After the first part 81 is adhesively pressed on the first adhesive-applying area 11, the second part 82 is pressed on the second adhesive-applying area 12, and the third part 83 is pressed on the third adhesive-applying area 13, the product 1 is moved from the second jig body 321 to be carried on the third jig body 331. Then, the pressure-holding driving mechanism 73 drives the first pressure-holding block 71 and the second pressure-holding block 72 to move towards each other and respectively press the first adhesive-applying area 11 and the second adhesive-applying area 12, that is, the first pressure-holding block 71 moves upward to press the second adhesive-applying area 12, and the second pressure-holding block 72 moves downward to press the second adhesive-applying area 12. At this time, the first pressure-holding surface 711 presses the first part 81 tightly on the first adhesive-applying area 11, the second pressure-holding surface 721 presses the second part 82 tightly on the second adhesive-applying area 12, and the first pressure-holding surface 711 is adapted to the first adhesive-applying area 11, and the second pressure-holding surface 721 is adapted to the second adhesive-applying area 12, so that the pressing effect of the first pressure-holding block 71 on the first adhesive-applying area 11 is better, and the pressing effect of the second pressure-holding block 72 on the second adhesive-applying area 12 is also better. The first pressure-holding block 71 and the second pressure-holding block 72 press the product 1 towards each other, so that the pressure-holding mechanism 7 can fix the product 1, and thus the third fixing jig 33 does not need to include a structure for pressing the product 1 on the third jig body 331.

[0071] The pressure-holding driving mechanism 73 includes a first pressure-holding driving unit 731, a pressure-holding mounting bracket 732, a second pressure-holding driving unit 733, and a third pressure-holding driving unit 734. The first pressure-holding driving unit 731 is arranged on the workbench 2, the pressure-holding mounting bracket 732 is arranged on the first pressure-holding driving unit 731, the second pressure-holding driving unit 733 and the third pressure-holding driving unit 734 are both arranged on the pressure-holding mounting bracket 732. The first pressure-holding driving unit 731, the second pressure-holding driving unit 733, and the third pressure-holding driving unit 734 can all be air cylinders, hydraulic cylinders, or push rod motors. The first pressure-holding block 71 is arranged at the output end of the second pressure-holding driving unit 733, and the second pressure-holding block 72 is arranged at the output end of the third pressure-holding driving unit 734. The first pressure-holding driving unit 731 drives the pressure-holding mounting bracket 732 to horizontally move towards the third fixture body 331. The second pressure-holding driving unit 733 and the third pressure-holding driving unit 734 horizontally move towards the third fixture body 331 along with the pressure-holding mounting bracket 732. The first pressure-holding block 71 horizontally moves along with the second pressure-holding driving unit 733 to directly below the first adhesive application area 11, and the second pressure-holding block 72 horizontally moves along with the third pressure-holding driving unit 734 to directly above the second adhesive application area 12. At this time, driving the first pressure-holding block 71 to move upward by the second pressure-holding driving unit 733 can make the first pressure-holding surface 711 press the first part 81 upward against the first adhesive application area 11, and driving the second pressure-holding block 72 to move downward by the third pressure-holding driving unit 734 can make the second pressure-holding surface 721 press the second part 82 downward against the second adhesive application area 12. It can be understood that the first pressure-holding unit and the pressure-holding mounting bracket 732 are not regarded as necessary elements. For example, in some embodiments, the second pressure-holding driving unit 733 and the third pressure-holding driving unit 734 can also be installed on the third fixed fixture 33 or the workbench 2, as long as it is ensured that the first pressure-holding surface 711 of the first pressure-holding block 71 arranged at the output end of the second pressure-holding driving unit 733 faces directly towards the first adhesive application area 11 and the second pressure-holding surface 721 of the second pressure-holding block 72 arranged at the output end of the third pressure-holding driving unit 734 faces directly towards the second adhesive application area 12.

[0072] The above embodiments only represent the preferred embodiments of the present invention. The description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
