Description

Technical Field

[0001] This utility model relates to the field of film application mechanisms, and in particular to a film application mechanism and film application equipment. Background Technology

[0002] In the manufacturing process of electronic products, surface coating is one of the key processes in the assembly stage. With the development of automation technology, automated coating mechanisms have gradually emerged. These mechanisms typically use a vacuum plate to adsorb the film to be coated, and rollers on one side of the vacuum plate roll the film onto the electronic device that needs coating. A robotic arm then moves the vacuum plate and rollers along the coating direction to attach and cover the electronic device with the protective film.

[0003] Traditional film application equipment typically uses a robotic arm to tilt the entire film application mechanism and position the rollers at their lowest point during the application process, thereby preventing the formation of air bubbles. This action requires the robotic arm to have an additional set of rotating shafts for adjusting the angle, and because these rotating shafts need to drive the entire film application mechanism to rotate, the load is relatively large. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the problem that the robot arm used for applying film in the prior art needs to add a set of rotating shafts for adjusting the angle, and that the load is large because the rotating shaft needs to drive the entire film application mechanism to rotate. Thus, a film application mechanism is provided.

[0005] To solve the above-mentioned technical problems, this utility model provides a film application mechanism, comprising:

[0006] Frame;

[0007] The tilting mechanism includes: a first driving member and a vacuum plate. The first driving member is disposed on the frame, and the vacuum plate is used to adsorb the film to be applied.

[0008] The bonding mechanism includes a second driving member and a roller. The second driving member is disposed on the frame, and the roller is rotatably connected to the output end of the second driving member. The roller is movably disposed on one side of the vacuum plate along a second direction, and the vacuum plate has a clearance groove adapted to the roller on its side along a first direction.

[0009] In one embodiment of the present invention, the vacuum plate has a guide surface on the side of the clearance groove near the second driving member. The guide surface includes a first vertical part and an inclined part. The first end of the first vertical part is connected to the clearance groove, and the second end extends in a second direction toward the second driving member. The first end of the inclined part is connected to the second end of the first vertical part, and the second end recedes away from the movement path of the roller.

[0010] In one embodiment of the present invention, the vacuum plate has a second vertical portion on the side of the clearance groove away from the second driving member, the first end of the second vertical portion is connected to the clearance groove and the other end extends away from the second driving member along the second direction.

[0011] In one embodiment of the present invention, the frame includes: a locking member, a fixing plate, and a support plate. The locking member is externally connected to the robot arm, the fixing plate is connected to the locking member, and one end of the support plate is connected to the fixing plate and the other end extends along a second direction and is hinged to the vacuum plate.

[0012] In one embodiment of the present invention, the first driving member and the second driving member are respectively disposed on both sides of the frame along the first direction, and the vacuum plate is provided with a first hinge assembly and a second hinge assembly on both sides along the first direction. The output ends of the frame and the first driving member are respectively hinged to the first hinge assembly and the second hinge assembly.

[0013] In one embodiment of the present invention, both the first hinge assembly and the second hinge assembly include: a hinge seat and a rotating shaft. The hinge seat is disposed on the vacuum plate, and the rotating shaft passes through the hinge seat and the end of the frame or the output end of the first drive member. The vacuum plate is hinged to the end of the frame or the output end of the first drive member through the rotating shaft.

[0014] In one embodiment of this utility model, the output end of the second driving member is connected to a lifting plate, the lifting plate is detachably mounted with an adjusting plate, the adjusting plate is provided with bearing seats at both ends along a third direction, and the two ends of the roller are rotatably connected to the adjusting plate through the bearing seats.

[0015] In one embodiment of the present invention, the lifting plate is provided with a plurality of mounting holes, and the adjusting plate is provided with a plurality of oblong holes adapted to the mounting holes along the second direction. The adjusting plate and the lifting plate are detachably connected by fasteners passing through the oblong holes and extending into the mounting holes.

[0016] In one embodiment of this utility model, the frame is provided with a pressure sensor, and the output end of the pressure sensor can abut against the lifting plate.

[0019] This utility model also provides a film application device, including the film application mechanism described above.

[0020] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0021] The film-applying mechanism of this invention uses a first driving component to rotate a vacuum plate around its connection point with the frame, adjusting the vacuum plate to a suitable tilt angle to ensure better adhesion of the film to be applied. Through the avoidance grooves provided on the vacuum plate, the rollers do not interfere with the end of the vacuum plate during its up-and-down movement when the vacuum plate is tilted, allowing for smooth alignment. During the application process, only the vacuum plate needs to rotate, eliminating one rotation axis compared to traditional robotic arms. Furthermore, the robotic arm does not need to tilt the entire film-applying mechanism when driving it, reducing the hardware and operating costs of the robotic arm. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0031] Example 1

[0032] In this embodiment, with Figure 1 Based on the reference, the first direction is the X-axis direction, the second direction is the Z-axis direction, and the third direction is the Y-axis direction.

[0033] Reference Figures 1-6 As shown, a film-applying mechanism of this utility model includes:

[0034] Frame 1;

[0035] The tilting mechanism includes: a first driving member 2 and a vacuum plate 4. The first driving member 2 is disposed on the frame 1, and the vacuum plate 4 is used to adsorb the film 7 to be applied. The vacuum plate 4 is rotatably connected to the frame 1 and the output end of the first driving member 2 on both sides along the first direction.

[0036] The bonding mechanism includes a second driving member 3 and a roller 6. The second driving member 3 is disposed on the frame 1. The roller 6 is rotatably connected to the output end of the second driving member 3. The roller 6 is movably disposed on one side of the vacuum plate 4 along the second direction. The vacuum plate 4 has a clearance groove 45 adapted to the roller 6 on its side along the first direction.

[0037] The film-applying mechanism of this utility model generates negative pressure through a vacuum plate 4, thereby firmly adsorbing the film 7 to be applied onto the vacuum plate 4. The frame 1 is externally connected to a robotic arm via a locking mechanism 11 or similar structure, making the entire film-applying mechanism movable. A first driving member 2 drives the vacuum plate 4 to rotate around its connection point with the frame 1, adjusting the vacuum plate 4 to a suitable tilt angle to ensure better adhesion of the film 7. A second driving member 3 drives a roller 6 to approach the vacuum plate 4 in a second direction. When the roller 6 contacts the film 7, the entire film-applying mechanism moves under the drive of the external robotic arm, causing the roller 6 to roll. During the rolling process, the roller 6 presses the film 7 off the vacuum plate 4 and adheres it to the surface of the target object. Because the vacuum plate 4 has a clearance groove 45, the roller 6 will not interfere with the end of the vacuum plate 4 during its up-and-down movement when the vacuum plate 4 is tilted, allowing for smooth alignment. During the bonding process, only the vacuum plate 4 needs to rotate, which reduces the number of rotating axes 42 compared to the traditional robotic arm structure to complete the bonding process. Furthermore, the robotic arm does not need to tilt the entire bonding mechanism when driving it, thus reducing the hardware and operating costs of the robotic arm.

[0038] Reference Figure 4As shown, the vacuum plate 4 has a guide surface on the side of the clearance groove 45 near the second driving member 3. The guide surface includes a first vertical portion 44 and an inclined portion 43. The first end of the first vertical portion 44 is connected to the clearance groove 45, and the second end extends in a second direction towards the second driving member 3. The first end of the inclined portion 43 is connected to the second end of the first vertical portion 44, and the second end recoils away from the movement path of the roller 6. The vacuum plate 4 generates negative pressure to adsorb the film 7 to be applied. When the film application operation is required, the second driving member 3 is activated, driving the roller 6 to move closer to the vacuum plate 4 in the second direction. During the process of the roller 6 approaching, it first approaches along the vertical direction that the first vertical portion 44 of the guide surface avoids. As the roller 6 continues to approach, after reaching the second end of the first vertical portion 44, it continues to move along the direction that the inclined portion 43 avoids. Because the inclined portion 43 recoils away from the movement path of the roller 6, the roller 6 can smoothly reach the position to contact the film 7 to be applied without interfering with the edge of the vacuum plate 4. Driven by an external robotic arm, the film-applying mechanism moves as a whole, causing the rollers 6 to roll. During this rolling process, the rollers 6 press the film 7 to be applied from the vacuum plate 4 and adhere it to the surface of the target object. Throughout the process, even if the vacuum plate 4 is adjusted to different tilt angles via the tilting mechanism, the guide surface provides appropriate guidance for the rollers 6, ensuring that the rollers 6 always move along the correct path, thereby achieving precise and reliable film-applying operation. In this embodiment, the maximum tilt angle of the vacuum plate 4 is 15°.

[0039] Reference Figures 3-4 As shown, the vacuum plate 4 has a second vertical portion 46 on the side of the clearance groove 45 away from the second driving member 3. The first end of the second vertical portion 46 is connected to the clearance groove 45, and the other end extends in a second direction away from the second driving member 3. The second vertical portion 46 is located on the lower side of the end of the vacuum plate 4, which improves the structural strength of the vacuum plate 4, avoids the end section of the vacuum plate 4 being an acute angle, and prevents the protective film from being cut when tilted.

[0040] Reference Figure 5 As shown, the frame 1 includes a locking member 11, a fixing plate 12, and a support plate 13. The locking member 11 is externally connected to the robot arm, the fixing plate 12 is connected to the locking member 11, and one end of the support plate 13 is connected to the fixing plate 12, while the other end extends along a second direction and is hinged to the vacuum plate 4. In this embodiment, the locking member 11 is a flange joint, which is connected to the robot arm. The fixing plate 12 is horizontally positioned, and the plane of the support plate 13 is perpendicular to the plane of the fixing plate 12. The output force of the first driving member 2 causes the vacuum plate 4 to rotate around the hinge point between the support plate 13 and the vacuum plate 4, thereby adjusting the tilt angle of the vacuum plate 4 to avoid the generation of air bubbles.

[0041] Reference Figure 1As shown, the first driving component 2 and the second driving component 3 are respectively disposed on both sides of the frame 1 along the first direction. The vacuum plate 4 is provided with a first hinge assembly and a second hinge assembly on both sides along the first direction. The output ends of the frame 1 and the first driving component 2 are respectively hinged to the first hinge assembly and the second hinge assembly. By disposing the first driving component 2 and the second driving component 3 on the left and right sides of the frame 1 respectively, and simultaneously disposing the locking component 11 in the middle of the fixing plate 12, the tensile force on both sides of the fixing plate 12 is more balanced, reducing the torsional force on the flange joint.

[0042] Reference Figure 3 As shown, both the first and second hinge components include a hinge base 41 and a rotating shaft 42. The hinge base 41 is disposed on the vacuum plate 4, and the rotating shaft 42 passes through the hinge base 41 and the end of the frame 1 or the output end of the first drive member 2. The vacuum plate 4 is hinged to the end of the frame 1 or the output end of the first drive member 2 via the rotating shaft 42. During the tilting process, relative rotation occurs between the hinge base 41 and the rotating shaft 42, with the rotating shaft 42 rotating within the shaft hole of the hinge base 41. A certain fitting precision and lubrication measures exist between the rotating shaft 42 and the hinge base 41, such as applying lubricating oil or using self-lubricating materials, to ensure smooth rotation and reduce frictional resistance and wear. Taking the upward movement of the output end of the first drive member 2 as an example, the output end of the first drive member 2 applies an upward pulling force to the vacuum plate 4 through the rotating shaft 42 in the second hinge component. Since the vacuum plate 4 is also hinged to the end of the frame 1 through the pivot 42 in the first hinge assembly, the vacuum plate 4 rotates around the pivot 42 in the first hinge assembly under the action of tension, thereby achieving the tilting of the vacuum plate 4.

[0043] Reference Figure 5 As shown, it also includes a connecting plate assembly 5, which includes a lifting plate 51 and an adjusting plate 53. The output end of the second driving component 3 is connected to the lifting plate 51, and the adjusting plate 53 is detachably mounted on the lifting plate 51. The adjusting plate 53 has bearing seats 56 at both ends along the third direction, and the two ends of the roller 6 are rotatably connected to the adjusting plate 53 through the bearing seats 56. The roller 6 is rotatably connected to the adjusting plate 53 through the bearing seats 56, and the use of bearings ensures that the roller 6 can rotate stably and flexibly. During the film application process, the roller 6 needs to continuously roll to press the film 7 to be applied onto the surface of the target object. Stable rotation performance can ensure that the rolling process is uniform and smooth, reducing film application defects caused by the roller 6 not rotating smoothly, such as film wrinkles, air bubble residue, etc. The first driving component 2 can drive the roller 6 to move up and down through the lifting plate 51 and the adjusting plate 53 to realize the height adjustment of the roller 6 in the second direction.

[0044] The lifting plate 51 has multiple mounting holes 55, and the adjusting plate 53 has multiple oblong holes 54 along the second direction that fit the mounting holes 55. The adjusting plate 53 and the lifting plate 51 are detachably connected by fasteners passing through the oblong holes 54 and extending into the mounting holes 55. The adjusting plate 53 can move freely along the second direction within the range of the oblong holes 54. Depending on actual needs, the adjusting plate 53 can be moved up or down to a suitable position. This ensures that the tilt angle of the vacuum plate 4 corresponding to the maximum driving length of the first driving member 2 is near the target tilt angle, reducing the stroke of the first driving member 2. During movement, the moving distance of the adjusting plate 53 can be determined by referring to a pre-set scale or by measurement to ensure that the roller 6 reaches the accurate position under the drive of the first driving member 2. After the adjusting plate 53 is moved to the suitable position, the nut is tightened again using a tool to firmly fix the adjusting plate 53 to the lifting plate 51.

[0045] Reference Figure 1 As shown, the frame 1 is equipped with a pressure sensor 8, and the lifting plate 51 has an abutment groove 52 adapted to the pressure sensor 8. The output end of the pressure sensor 8 can abut against the lifting plate 51. When the first driving member 2 drives the lifting plate 51 to approach the film 7 to be applied, the pressure between the lifting plate 51 and the output end of the pressure sensor 8 gradually increases. The pressure sensor 8 monitors this pressure change in real time and converts the sensed pressure signal into an electrical signal or other form, which is transmitted to the control system through a signal line. The control system analyzes and processes the received pressure signal in real time. During the process of the roller 6 contacting the film 7 to be applied and starting to roll, the pressure sensor 8 continuously monitors the pressure on the lifting plate 51. If the pressure value is lower than the preset minimum pressure threshold, it indicates that the pressure of the roller 6 on the film is insufficient, which may lead to poor adhesion. The control system will issue a command to increase the output force of the second driving member 3, so that the roller 6 applies greater pressure. Conversely, if the pressure value exceeds the preset maximum pressure threshold, it indicates that the pressure of the roller 6 on the diaphragm is too high, which may damage the diaphragm or the surface of the target object. The control system will then issue a command to reduce the output force of the second drive unit 3 and reduce the pressure of the roller 6.

[0046] Reference Figure 6As shown, the vacuum plate 4 includes a plate body with multiple flow channels 47. One end of each flow channel 47 is connected to a negative pressure unit, and the other end extends to the side of the plate body near the electronic device to be bonded. The negative pressure unit is activated. It generates negative pressure internally and transmits this pressure to the flow channels 47 of the vacuum plate 4 via connecting pipes. The negative pressure propagates rapidly along the flow channels 47 towards the surface of the plate body near the side of the film 7 to be bonded. Because the flow channels 47 are evenly distributed across the plate body surface, when the negative pressure reaches the outlet of the flow channel 47 on the plate body surface, a uniform negative pressure area is formed across the entire plate body surface. This negative pressure area generates an adsorption force on the film 7 to be bonded. As the negative pressure continues to act, the adsorption force gradually increases, tightly adhering the film 7 to the vacuum plate 4.

[0047] The roller 6 is covered at least circumferentially with a flexible sleeve. The flexible sleeve allows the roller 6 to apply pressure more evenly to the film 7 during rolling, effectively reducing air bubbles and wrinkles, improving the flatness and adhesion of the film, and thus enhancing the quality of the film application. It also prevents the roller 6 from rigidly scratching or abrading the surface of the film 7 and the target object. The flexible sleeve's softness adapts to different materials and surface conditions of the film 7 and the target object, protecting their surface integrity. It also cushions the impact and friction forces experienced by the roller 6 during operation, reducing wear and damage, extending the roller 6's service life, and lowering maintenance and replacement costs. Furthermore, because the flexible sleeve is relatively easy to replace, when it wears or is damaged, only the flexible sleeve can be replaced, without replacing the entire roller 6.

[0048] Example 2

[0049] A film application device includes a film application mechanism as described in Embodiment 1.

[0050] This embodiment describes a screen protector applicator, comprising an applicator mechanism, a robotic arm, a control system, a negative pressure unit, and other components. The frame 1 is securely connected to the end effector of the robotic arm via locking components 11, ensuring a tight and reliable connection to guarantee the robotic arm can accurately drive the applicator mechanism. The negative pressure unit is installed in a suitable position and sealed to one end of the flow channel 47 of the vacuum plate 4 via a pipe, ensuring no leakage occurs during negative pressure transmission. Simultaneously, a pressure sensor 8 is installed at a predetermined position on the frame 1, ensuring its output end accurately abuts against the lifting plate 51, guaranteeing that the pressure sensor 8 can monitor pressure changes on the lifting plate 51 in real time and accurately. Before applicating the screen protector, the screen protector 7 and the target object need to be pre-treated. The screen protector 7 is cleaned to remove surface dust and impurities to ensure effective applicator application; the target object surface is also cleaned and treated accordingly to ensure it is smooth and clean. The negative pressure unit generates negative pressure within the flow channel 47 of the vacuum plate 4, firmly adsorbing the screen protector 7 onto the side of the vacuum plate 4 closest to the phone to be applicated. After roller 6 contacts the film to be applied 7, the film-applying mechanism moves as a whole under the drive of the external robotic arm, causing roller 6 to roll. During the rolling process, the flexible sleeve around roller 6 applies pressure evenly to the film to be applied 7, pressing the film to be applied 7 from the vacuum plate 4 and adhering it to the surface of the target object. Pressure sensor 8 monitors the pressure changes on lifting plate 51 in real time and transmits the pressure signal to the control system. The control system adjusts the working state of the first drive component 2 and the second drive component 3 in real time according to the preset pressure threshold and the actual monitored pressure signal to ensure that roller 6 performs the film-applying operation under appropriate pressure to obtain a good film-applying effect.

[0051] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
