Description

Technical Field

[0001] This application belongs to the field of film application technology, and specifically relates to a film application device. Background Technology

[0002] In existing film lamination equipment, rollers are used to press and adhere a second part (such as a protective film) onto a first part. When the first part has an irregular shape (e.g., a shape with curved edges), the rollers can only press the second part tightly against the flat portion of the first part. Specifically, when the curved edge of the first part is lower than the flat portion, the rollers cannot descend and apply pressure to the curved edge. This results in air bubbles and wrinkles easily forming when the curved edge of the first part comes into contact with the second part. Utility Model Content

[0003] The purpose of this application is to provide a film-applying device that aims to solve the problem that sealed air bubbles and curved edge wrinkles are easily generated when the arc-shaped edge of the first part to be applied comes into contact with the second part to be applied, thereby improving product quality.

Detailed Implementation

[0050] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0051] Embodiments of this application provide a film application device, such as... Figure 1 , Figure 2As shown, the film-applying device includes a longitudinal moving mechanism 2 and a vertical moving mechanism 3; a first piece to be applied 5 is fixed on the longitudinal moving mechanism 2; the vertical moving mechanism 3 is connected to a rolling shaft 302, which is positioned above the longitudinal moving mechanism 2, and the vertical moving mechanism 3 drives the rolling shaft 302 to move vertically; the longitudinal moving mechanism 2 and the vertical moving mechanism 3 cooperate with each other to sequentially roll and apply the second piece to be applied onto the planar portion, the first arcuate portion, and the second arcuate portion of the first piece to be applied 5.

[0052] Specifically, such as Figure 3 As shown, the first part to be bonded 5 has a flat portion and a curved portion, with the curved portion being lower than the flat portion. Before the second part to be bonded is bonded to the first part to be bonded 5 using the film-applying device, the first part to be bonded 5 is fixed on the longitudinal moving mechanism 2, and one end of the second part to be bonded protrudes beyond the flat portion of the first part to be bonded 5 (this protruding portion is subsequently used to bond with the curved portion). Because the second part to be bonded itself has a certain degree of hardness and only protrudes to the length used to bond with the curved portion, the protruding portion remains in a non-contact state with the curved portion before rolling, which can avoid the formation of air bubbles during the initial bonding. First, the longitudinal moving mechanism 2 moves until the starting end of the planar portion of the first part to be bonded 5 is directly below the rolling shaft 302. Then, the vertical moving mechanism 3 drives the rolling shaft 302 closer to the first part to be bonded 5, bonding the second part to be bonded to the starting end of the planar portion of the first part to be bonded 5. After bonding at the starting end of the planar portion, the longitudinal moving mechanism 2 moves towards the end of the planar portion of the first part to be bonded 5, while the rolling shaft 302 applies uniform pressure to the bonding surface of the planar portion to continuously roll and bond the second part to be bonded to the planar portion of the first part to be bonded 5. When the end of the planar portion of the first part to be bonded 5 moves below the rolling shaft 302, the longitudinal moving mechanism 2 continues to move while maintaining its current direction of movement, while the vertical moving mechanism 3 drives the rolling shaft 302 to move vertically downward, meaning the rolling shaft 302 remains in close contact with the first part to be bonded 5. The first arc-shaped portion rolls because the longitudinal moving mechanism 2 controls the longitudinal movement of the first part to be bonded 5, and the vertical moving mechanism 3 controls the vertical movement of the rolling shaft 302. The two work together to make the rolling shaft 302 roll tightly against the arc-shaped surface of the first part to be bonded 5, completing the rolling bonding of the first arc-shaped portion. Then, the vertical moving mechanism 3 drives the rolling shaft 302 to move vertically upward to reset, while the longitudinal moving mechanism 2 changes its direction of movement and returns to the initial bonding position, and continues to move in the extension direction of the second arc-shaped portion. At the same time, the vertical moving mechanism 3 drives the rolling shaft 302 to move vertically downward again. Similarly, the cooperation between the longitudinal moving mechanism 2 and the vertical moving mechanism 3 makes the rolling shaft roll tightly against the second arc-shaped portion of the first part to be bonded 5, completing the rolling bonding of the second arc-shaped portion. Thus, the entire rolling bonding operation of the first part to be bonded 5 is completed.

[0053] The film-applying device in this embodiment has a simple structure. The longitudinal moving mechanism 2 controls the longitudinal movement of the first part to be applied 5, and the vertical moving mechanism 3 controls the vertical movement of the rolling shaft 302. The two work together to roll and apply the second part to be applied onto the flat part, the first arc part, and the second arc part of the first part to be applied 5 in sequence. By applying the film in sections, each section has relatively sufficient time and space to allow air to escape naturally, which can prevent air bubbles from forming when the second part to be applied and the arc parts at both ends of the first part to be applied 5 are applied.

[0054] In one embodiment of this application, such as Figure 4 As shown, the longitudinal moving mechanism 2 includes a first mounting module 201, a first part-to-be-attached placement platform 202, and a first adsorption module; the first mounting module 201 is movably mounted on the mounting base 1; the first part-to-be-attached placement platform 202 is mounted on the first mounting module 201; the first adsorption module is mounted on the first part-to-be-attached placement platform 202, and the first part-to-be-attached 5 is adsorbed on the top surface of the first part-to-be-attached placement platform 202.

[0055] Specifically, the longitudinal moving mechanism 2 further includes a first driving component 206 (such as a rotary motor), a first lead screw, and a first threaded block. The first driving component 206 is disposed at one longitudinal end of the mounting base 1. The first lead screw is drivenly connected to the first driving component 206 and is distributed longitudinally on the mounting base 1. The first threaded block is sleeved on the first lead screw and threadedly connected to it. The first threaded block is connected to the bottom of the first mounting module 201. Under the driving action of the first driving component 206, the first threaded block moves along the length direction of the first lead screw. The first mounting module 201 and the components disposed on the first mounting module 201 (such as the first placement platform 202 for the part to be bonded and the first adsorption module) all move longitudinally on the mounting base 1. Here, longitudinal refers to the length direction of the mounting base, and transverse refers to the width direction of the mounting base.

[0056] The first mounting module 201 includes a first mounting base plate, a first side plate, a second side plate, and a mounting top plate. A first threaded block is connected to the bottom of the first mounting base plate. The first side plate and the second side plate are respectively disposed on the lateral sides of the first mounting base plate and connected to the first mounting base plate. The mounting top plate is disposed on top of the first side plate and the second side plate. The first mounting base plate, the first side plate, the second side plate, and the mounting top plate together form an mounting space 2011. The first part-to-be-attached placement platform 202 is plate-shaped and disposed above the mounting top plate. A first negative pressure chamber is formed inside the first part-to-be-attached placement platform 202. A first negative pressure hole 2023 communicating with the first negative pressure chamber is formed on the top wall of the first negative pressure chamber. A first adsorption module is disposed on the first part-to-be-attached placement platform 202 and communicates with the first negative pressure chamber. When the first adsorption module is opened, it can adsorb and fix the first part-to-be-attached 5 on the top surface of the first part-to-be-attached placement platform 202 to prevent the first part-to-be-attached 5 from moving arbitrarily. Furthermore, the first adsorption module includes a first vacuum component, a first airflow channel, and a first vacuum pump. The two ends of the first airflow channel are connected to the first vacuum component and the first vacuum pump, respectively. The first vacuum component is placed on the first bonding component placement platform 202 and is connected to the first negative pressure chamber. After the first vacuum pump is turned on, it can perform vacuum treatment on the first negative pressure chamber, thereby forming a negative pressure state in the first negative pressure chamber and adsorbing the first bonding component 5.

[0057] In one embodiment of this application, such as Figure 4 As shown, the longitudinal moving mechanism 2 also includes a first clamping module 203 and a second clamping module 204 for clamping and positioning the first part to be bonded 5. The first clamping module 203 and the second clamping module 204 are located on adjacent sides of the first part to be bonded placement platform 202. After the first part to be bonded 5 is clamped by the first clamping module 203 and the second clamping module 204, the stability of the first part to be bonded 5 on the first part to be bonded placement platform 202 is further ensured, and the first part to be bonded 5 is also positioned in a centered state on the first part to be bonded placement platform 202, ensuring the bonding accuracy of the second part to be bonded and the first part to be bonded 5.

[0058] In one embodiment of this application, such as Figure 4 , Figure 5 As shown, both the first clamping module 203 and the second clamping module 204 include several clamping components 205 arranged opposite to each other. Each clamping component 205 includes a telescopic member 2051 and a clamping member 2052. The telescopic member 2051 and the clamping member 2052 are driven to be connected. The clamping member 2052 is arranged vertically relative to the first bonding platform 202.

[0059] Specifically, in this embodiment, the clamping member 2052 is disposed at the telescopic end of the telescopic member 2051 and is vertically disposed relative to the first piece to be bonded placement platform 202. The clamping member 2052 protrudes upward from the first piece to be bonded placement platform 202 and applies a lateral thrust to the first piece to be bonded 5.

[0060] Preferably, there are two sets of the first clamping module 203 and the second clamping module 204, which ensures the uniformity of force on the first part to be bonded 5 and helps to further improve the accuracy of the centering positioning of the first part to be bonded 5 on the first part to be bonded placement platform 202. The first part to be bonded placement platform 202 has a first clearance portion 2021 and a second clearance portion 2022. The first clamping module 203 is disposed in the installation space 2011 and located in the first clearance portion 2021, and the second clamping module 204 is disposed in the installation space 2011 and located in the second clearance portion 2022. The telescopic components 2051 (such as telescopic cylinders) of the first clamping module 203 are distributed laterally, and the telescopic components 2051 (such as telescopic cylinders) of the second clamping module 204 are distributed longitudinally. When the two telescopic components 2051 of the first clamping module 203 extend, they drive the two clamping components 2052 of the first clamping module 203 to move closer to each other and apply a lateral thrust to the first part to be bonded 5 from both sides of the lateral direction, thereby clamping and positioning the first part to be bonded 5 from both sides of the lateral direction. Similarly, when the two telescopic components 2051 of the second clamping module 204 extend, they drive the two clamping components 2052 of the second clamping module 204 to move closer to each other and apply a lateral thrust to the first part to be bonded 5 from both sides of the longitudinal direction, thereby clamping and positioning the first part to be bonded 5 from both sides of the longitudinal direction.

[0061] In one embodiment of this application, such as Figure 5 As shown, the clamping assembly 205 also includes a mounting block 2055 and a first elastic member 2056; the mounting block 2055 is disposed at the telescopic end of the telescopic member 2051, and the clamping member 2052 is vertically disposed on the mounting block 2055, and the clamping member 2052 is flexibly disposed on the mounting block 2055; the clamping member 2052 includes a connecting rod portion 2053 and a clamping portion 2054, the clamping portion 2054 is located at the end of the connecting rod portion 2053 away from the telescopic end of the telescopic member, the first elastic member 2056 is sleeved on the outside of the connecting rod portion 2053, one end of the first elastic member 2056 abuts against the clamping portion 2054, and the other end of the first elastic member 2056 abuts against the mounting block 2055.

[0062] Specifically, such as Figure 5As shown, the maximum width of the clamping part 2054 is greater than the outer diameter of the connecting rod part 2053. In this embodiment, the first elastic element 2056 can be selected as a spring. The clamping member 2052 applies a lateral thrust to the first part to be bonded 5 through the clamping part 2054. When the clamping member 2052 has not moved below the rolling shaft 302, and the first elastic element 2056 is in an extended state, the clamping part 2054 is at a preset height position and part of the clamping part 2054 protrudes from the first part to be bonded 5; as Figure 5 , Figure 8 As shown, when the clamping member 2052 moves below the rolling shaft 302, the rolling shaft 302 applies downward pressure to the clamping member 2052. The first elastic member 2056 changes from an extended state to a retracted state, and the clamping member 2052 descends relative to the mounting block 2055 so that the rolling shaft 302 rolls over the position of the clamping member 2052 without any movement interference between them. The above arrangement enables the first clamping module 203 and the second clamping module 204 to reliably perform clamping and positioning functions, and avoids movement interference with the rolling shaft 302, thereby improving the reliability of the film application device.

[0063] In one embodiment of this application, such as Figures 7-9 As shown, the top surface of the clamping part 2054 is an arc surface. The above-mentioned arrangement can reduce the contact area when the rolling shaft 302 rolls over the clamping part 2054, avoid damage to the clamping part 2054 and the rolling shaft 302, and help extend the service life of the first clamping module 203, the second clamping module 204 and the rolling shaft 302.

[0064] In one embodiment of this application, such as Figure 6 As shown, the vertical moving mechanism 3 includes a drive module and a roller mounting module 301;

[0065] The drive module drives the roller mounting module 301 to move vertically above the longitudinal moving mechanism 2;

[0066] The rolling shaft 302 is rotatably mounted on the roller mounting module 301 and distributed laterally.

[0067] Specifically, the vertical moving mechanism 3 also includes a first mounting gantry 303 disposed on one side of the longitudinal moving mechanism 2. The drive module drives the roller mounting module 301 to move vertically on the first mounting gantry 303. The drive module includes a second drive member 304 (such as a rotary motor), a second lead screw, and a second threaded block. The second drive member 304 is disposed on one side of the first mounting gantry 303. The second lead screw is driven and connected to the second drive member 304 and distributed vertically. The second threaded block is sleeved on the second lead screw and threadedly connected to the second lead screw. The second threaded block is connected to the roller mounting module 301. Under the driving action of the second drive member 304, the second threaded block moves along the length direction of the second lead screw. The roller mounting module 301 and the components disposed on the roller mounting module 301 (such as the rolling shaft 302) all move vertically on the first mounting gantry 303 to realize the height adjustment of the rolling shaft 302 and finally realize the rolling of the arc-shaped parts at both ends of the first part to be bonded 5. Furthermore, the roller 302 is rotatably mounted on the roller mounting module 301, which allows the roller 302 to roll relative to the second part to be bonded and the first part to be bonded 5 when the longitudinal moving mechanism 2 moves longitudinally, so that the second part to be bonded and the first part to be bonded 5 are bonded together by roller bonding, which can further avoid the generation of air bubbles when the second part to be bonded and the first part to be bonded 5 are bonded together.

[0068] In one embodiment of this application, the roller mounting module 301 includes a connecting rod 3012, a roller mounting assembly 3013, and a second elastic member 3014;

[0069] The drive module drives the connecting rod 3012 to move vertically;

[0070] The roller mounting assembly 3013 is movably mounted on the connecting rod 3012, and the rolling shaft 302 is rotatably mounted on the roller mounting assembly 3013;

[0071] The second elastic element 3014 is sleeved on the outside of the connecting rod 3012, and one end of the second elastic element 3014 abuts against the roller mounting assembly 3013.

[0072] Specifically, in this embodiment, the second elastic element 3014 can be selected as a spring. The roller mounting assembly 3013 includes a roller mounting block 3017, a roller mounting plate 3018, and a roller mounting seat 3019. The first roller mounting block 3017 is movably mounted on the connecting rod 3012. The roller mounting plate 3018 is connected to the roller mounting block 3017 and distributed laterally. The roller mounting seat 3019 is mounted on the roller mounting plate 3018 and distributed laterally. The rolling shaft 302 is rotatably mounted on the roller mounting seat 3019. Under the driving action of the second driving element 304, the driving module moves along the axial direction of the second lead screw through the driving connecting block 3011, thereby driving the connecting rod 3012, roller mounting block 3017, roller mounting plate 3018, roller mounting seat 3019, second elastic element 3014, and rolling shaft 302 connected to the connecting block 3011 to move vertically. When there is a difference between the actual profile of the first part to be bonded 5 and its theoretical profile (when the first part to be bonded 5 is glass, since the curved surface of the glass is formed by hot bending, there is a slight difference between the actual profile of the glass and its theoretical profile; the actual profile of the curved surface of the glass has an upper limit, a middle limit, and a lower limit, while its theoretical profile is the middle limit), the vertical moving mechanism 3 can adaptively adjust the height of the rolling shaft 302 through the elastic extension and contraction of the second elastic element 3014. This allows the rolling shaft 302 to apply a uniform rolling force during the rolling and bonding process of the second part to be bonded and the first part to be bonded 5, ensuring that the second part to be bonded is pressed firmly onto the curved surface of the first part to be bonded 5, which helps to further avoid air bubbles forming between the second part to be bonded and the curved surface of the first part to be bonded 5.

[0073] In one embodiment of this application, the roller mounting module 301 further includes a first anti-deformation pressure roller 3015 and a second anti-deformation pressure roller 3016;

[0074] Both the first anti-deformation pressure roller 3015 and the second anti-deformation pressure roller 3016 are rotatably mounted on the roller mounting assembly 3013, and are located above the rolling shaft 302, forming a triangular support structure with the rolling shaft 302.

[0075] Specifically, in this embodiment, the first anti-deformation pressure roller 3015 and the second anti-deformation pressure roller 3016 are both mounted on the roller mounting base 3019. The roller 302, the first anti-deformation pressure roller 3015 and the second anti-deformation pressure roller 3016 are arranged in a triangular distribution on the roller mounting base 3019. The first anti-deformation pressure roller 3015 and the second anti-deformation pressure roller 3016 can both be made of stainless steel.

[0076] When the lateral width of the second part to be bonded and the first part to be bonded 5 is greater than 200mm, the length of the rolling roller 302 is relatively long, which makes the rolling roller 302 prone to deformation during the rolling process. This will result in unstable rolling bonding effect of the second part to be bonded and the first part to be bonded 5. In this embodiment, the first anti-deformation pressure roller 3015 and the second anti-deformation pressure roller 3016 are set to form a triangular support structure. During the rolling process, they provide support and force dispersion for the rolling roller, thereby reducing the bending stress and deformation risk borne by the rolling roller itself and avoiding the situation where the rolling roller 302 deforms.

[0077] In one embodiment of this application, such as Figures 10-12 As shown, the film application device also includes a film taking mechanism 4, which includes a second mounting module 401, a second adsorption platform 402 for the part to be applied, and a second adsorption module.

[0078] The second mounting module 401 is movably positioned above the longitudinal moving mechanism 2;

[0079] The second adsorption platform 402 for the part to be bonded is rotatably connected to the second mounting module 401.

[0080] The second adsorption module is set on the adsorption platform 402 of the second part to be bonded, and the second part to be bonded is adsorbed at the bottom of the adsorption platform 402.

[0081] Specifically, the film-applying device also includes a second mounting gantry 7, a third driving component 8 (such as a rotary motor), a third lead screw 9, a third threaded block 10, and a second mounting module mounting base 11. The third driving component 8 is located on the top lateral side of the second mounting gantry 7. The third lead screw 9 is drivenly connected to the third driving component 8 and is distributed laterally on the top of the second mounting gantry 7. The third threaded block 10 is sleeved on the third lead screw 9 and threadedly connected to the third lead screw 9. The third threaded block 10 is connected to the second mounting module mounting base 11. The second mounting module 401 is located on the second mounting module mounting base 11. Under the driving action of the third driving component 8, the third threaded block 10 moves along the length direction of the third lead screw. The second mounting module mounting base 11 and the components located on the second mounting module mounting base 11 (such as the second mounting module 401, the second adsorption platform 402 for the part to be applied, and the second adsorption module, etc.) all move laterally on the second mounting gantry 7.

[0082] like Figure 11 , Figure 12As shown, the second mounting module 401 includes a vertically movable mounting plate 4011 and a first mounting support 4012. The film application device also includes a second mounting support 12, a deflection drive 13, a fourth drive 14 (such as a rotary motor), a fourth lead screw, and a fourth threaded block. The vertically movable mounting plate 4011 is vertically mounted on the second mounting module mounting base 11. The fourth drive 14 (such as a rotary motor) is mounted on the vertically movable mounting plate 4011. The fourth lead screw is drivenly connected to the fourth drive 14 and distributed vertically. The fourth threaded block... The block is fitted onto the fourth lead screw and threadedly connected to the fourth lead screw. The fourth threaded block is connected to the first mounting support 4012. The second mounting support 12 is positioned above the second adsorption platform 402 and is rotatably connected to the first mounting support 4012 via a rotating shaft. Under the driving action of the fourth driving component 14, the fourth threaded block moves along the length direction of the fourth lead screw, so that the first mounting support 4012, the second mounting support 12, the second adsorption platform 402, and the second adsorption module can all move vertically. In this embodiment, the deflection drive 13 can be selected as a telescopic drive (such as a telescopic cylinder) and is distributed at an inclination relative to the horizontal plane. Part of the deflection drive 13 is disposed in the mounting cavity inside the first mounting support 4012. The drive end of the deflection drive 13 is connected to the second adsorption platform 402 to be bonded. When the deflection drive 13 performs a telescopic operation, the second adsorption platform 402 to be bonded can deflect relative to the horizontal plane so that after the second adsorption platform 402 picks up the second adsorption platform to be bonded, the second adsorption platform to be bonded deflects at a certain angle during the tensioning and film application process, thereby maintaining a certain distance from the first adsorption platform 5 so that the second adsorption platform to be bonded can be rolled and bonded to the first adsorption platform 5 more conveniently.

[0083] Furthermore, a second negative pressure chamber is formed inside the second adsorption platform 402 for the second part to be bonded. A second negative pressure hole is formed on the bottom wall of the second negative pressure chamber, communicating with the second negative pressure chamber. The second adsorption module is disposed on the second part to be bonded placement platform and communicates with the second negative pressure chamber. After the second adsorption module is turned on, it can adsorb and fix the second part to be bonded on the bottom surface of the second part to be bonded adsorption platform to prevent the second part to be bonded from moving arbitrarily. Furthermore, the second adsorption module includes a second vacuum component, a second airflow channel, and a second vacuum pump. The two ends of the second airflow channel are respectively connected to the second vacuum component and the second vacuum pump. The second vacuum component is disposed on the second part to be bonded placement platform and communicates with the second negative pressure chamber. After the second vacuum pump is turned on, it can perform vacuum treatment on the second negative pressure chamber, thereby creating a negative pressure state in the second negative pressure chamber and adsorbing the second part to be bonded.

[0084] In one embodiment of this application, the film-applying device further includes a second mounting base plate 15, a film feeding mechanism 16, a conveying mechanism 17, and a transfer mechanism 18. The film feeding mechanism 16, the conveying mechanism 17, the transfer mechanism 18, the mounting base 1, and the vertical moving mechanism 3 are all disposed on the second mounting base plate 15. The film feeding mechanism 16 is used to provide a second part to be applied, the conveying mechanism 17 is used to convey a first part to be applied 5, and the transfer mechanism 18 is used to transfer the first part to be applied 5 from the conveying mechanism 17 to the vertical moving mechanism 2.

[0085] like Figures 13-14As shown, the film delivery mechanism 16 includes a film delivery mounting base 1601, a film delivery drum 1602, a stop bar 1603, a film taking platform 1604, a rotating rod 1605, a first transmission belt assembly 1606, a fifth driving component 1607 (such as a rotary motor), and a sensor 1608 for sensing a second component to be bonded. The film delivery drum 1602 is rotatably mounted above one longitudinal end of the film delivery mounting base 1601. The stop bar 1603 is mounted on the vertical sidewall of the transverse side of the film delivery mounting base 1601 and is located at the same longitudinal end as the film delivery drum 1602. The film taking platform 1604 is horizontally mounted on the film delivery mounting base. The rotating rod 1605 is rotatably mounted on the vertical sidewall of the transverse side of the film delivery mounting base 1601 and located below the stop rod 1603. The axial directions of the film delivery drum 1602, the stop rod 1603, and the rotating rod 1605 are parallel. The fifth driving member 1607 is located inside the film delivery mounting base 1601 and is drivenly connected to the rotating rod 1605 through the first transmission belt assembly 1606. The sensor 1608 is located at the end of the film taking platform 1604 away from the stop rod 1603 and is communicatively connected to the fifth driving member 1607. The second part to be bonded is bonded to the release film, and the two together form the roll film 6. The first end of the roll film 6 is wound on the roll film drum 1602, and the second end of the roll film 6 successively passes over the bottom of the stop bar 1603, the top surface of the film taking platform 1604, and the bottom surface of the film taking platform 1604 and is wound on the rotating rod 1605. Under the driving action of the fifth driving member 1607, the fifth driving member 1607 drives the first transmission belt assembly 1606 and the rotating rod 1605 to rotate. After the fifth driving member 1607 rotates, the roll film 6 with the second part to be bonded is continuously output from the roll film drum 1602. When the sensor 1608 senses that the second part to be bonded has reached the position of the sensor 1608, the roll film 6 is continuously output from the roll film drum 1602. At this time, the fifth driving component 1607 stops driving. At this time, the second piece to be bonded is located on the film taking platform 1604, so that the second piece to be bonded adsorption platform 402 moves above the film taking platform 1604 under the driving action of the third driving component 8, and adsorbs the second piece to be bonded from the film taking platform 1604 under the action of the second adsorption module. After the second piece to be bonded is adsorbed, the second piece to be bonded adsorption platform 402 moves above the longitudinal moving mechanism 2 under the driving action of the third driving component 8. In addition, after the second piece to be bonded is adsorbed, only the release film remains on the film taking platform 1604. Then the fifth driving component 1607 drives again to make the film roll drum 1602 output film again.

[0086] like Figure 15As shown, the conveying mechanism 17 includes a conveying drive motor 1701, a conveying roller mounting bracket 1702, and multiple conveying rollers 1703. The conveying roller mounting bracket 1702 is mounted on the second mounting base plate 15 and on one side of the mounting base 1. The multiple conveying rollers 1703 are rotatably mounted on the conveying roller mounting bracket 1702 and distributed longitudinally at intervals. The multiple conveying rollers 1703 together form a conveying channel for conveying the first piece to be bonded 5. The conveying drive motor 1701 is mounted on the conveying roller mounting bracket 1702 and is drivenly connected to the multiple conveying rollers 1703. When the conveying drive motor 1701 performs its driving action, the first piece to be bonded 5 is conveyed from the inlet end of the conveying channel to the outlet end of the conveying channel, thus completing the conveying of the first piece to be bonded 5.

[0087] like Figure 16As shown, the transfer mechanism 18 includes a third mounting gantry 1801, a sixth drive member 1802 (such as a rotary motor), a second transmission belt assembly 1803, a transmission connector, a lateral movement mounting base 1804, a seventh drive member 1805 (such as a rotary motor), a sixth lead screw, a sixth threaded block, a suction cup mounting plate 1806, and multiple suction cups 1807 mounted on the suction cup mounting plate 1806. The third mounting gantry 1801 is laterally positioned outside the transfer mechanism 17, the sixth drive member 1802 is mounted on the third mounting gantry 1801, and the second transmission belt assembly... 1803 is mounted on the third mounting gantry 1801 and distributed laterally. The sixth driving member 1802 is driven and connected to the drive wheel of the second transmission belt assembly 1803. The transmission connecting member is mounted on the transmission belt of the second transmission belt assembly 1803 and is connected to the lateral moving mounting base 1804. The seventh driving member 1805 is mounted on the lateral moving mounting base 1804. The sixth lead screw is driven and connected to the seventh driving member 1805 and distributed vertically. The sixth threaded block is sleeved on the sixth lead screw and threadedly connected to the sixth lead screw. The sixth threaded block is connected to the suction cup mounting plate 1806. When the first piece to be bonded 5 is conveyed to the outlet of the transmission channel, the sixth drive unit 1802 performs the drive function. Under the drive of the sixth drive unit 1802, the sixth threaded block moves along the length direction of the sixth lead screw. The lateral moving mounting base 1804 and other components connected to the lateral moving mounting base 1804 all move laterally until the suction cup mounting plate 1806 reaches above the first piece to be bonded 5. Then, the seventh drive unit 1805 performs the drive function. Under the drive of the seventh drive unit 1805, the sixth threaded block moves along the length direction of the seventh lead screw. The suction cup mounting plate 1806 and the multiple suction cups 1807 on the suction cup mounting plate 1806 move downward to adsorb the first piece to be bonded 5. After the first piece to be bonded 5 is adsorbed by the multiple suction cups 1807, the seventh drive unit 1805 drives the suction cup mounting plate 1806 and the suction cup mounting plate 1807 to move downward to adsorb the first piece to be bonded 5. Multiple suction cups 1807 on 806 move upward a preset distance; after the suction cup mounting plate 1806 and the multiple suction cups 1807 on the suction cup mounting plate 1806 move upward into position, the sixth driving member 1802 executes the driving function so that the mounting base 1804 moves laterally under the driving action of the sixth driving member 1802, carrying the first piece to be bonded 5 laterally to the top of the vertical moving mechanism 2 (at this time, the vertical moving mechanism 2 is in the preset receiving position on the mounting base 1); after the first piece to be bonded 5 moves laterally to the top of the vertical moving mechanism 2, the seventh driving member 1805 executes the driving function again so that the suction cup mounting plate 1806 and the multiple suction cups 1807 on the suction cup mounting plate 1806 move downward, so that the first piece to be bonded 5 can be placed on the first piece to be bonded placement platform 202 of the vertical moving mechanism 2, and the first piece to be bonded 5 is thus transferred.

[0088] The bonding device in this application can automatically, accurately, and efficiently bond the second part to be bonded to the first part to be bonded 5. The longitudinal moving mechanism 2 and the vertical moving mechanism 3 cooperate with each other to sequentially roll and bond the second part to be bonded to the flat part, the first arc part, and the second arc part of the first part to be bonded 5. This can effectively avoid air bubbles when the second part to be bonded and the arc parts at both ends of the first part to be bonded 5 are bonded, which is conducive to improving product quality and user experience.
