Meanwhile, referring to fig. 1 to 2, the automatic film pasting device 10 provided by the present invention is used for pasting a film 20 on a workpiece 30, wherein the film 20 may be a flexible film 20, and the workpiece 30 may be an OLED (organic light-Emitting Diode) flexible display screen.
First embodiment
Referring to fig. 1 to 2 together, the automatic film laminating apparatus 10 includes a carrier tape 100, a pressing mechanism 200, and a cleaning mechanism 300. Carrier tape 100 has adhesive side 110 and non-adhesive side 120, with both adhesive side 110 and non-adhesive side 120 oriented exactly opposite, and obviously, non-adhesive side 120 is not tacky. The carrier tape 100 is used for adsorbing the film 20 and attaching the film 20 to the work 30, and specifically, the film 20 has an adhesive surface 21 and a non-adhesive surface 21, and the adhesive surface 21 and the non-adhesive surface 21 are opposite in orientation, and it is obvious that the non-adhesive surface 21 does not have viscosity. The non-adhesive surface 21 of the film 20 is attached to the adhesive surface 110 of the carrier tape 100, and when pressure is applied to the carrier tape 100, the adhesive surface 21 of the film 20 is attached to the surface of the work 30, thereby achieving attachment of the film 20 to the work 30.
The pressing mechanism 200 is used to apply a force to the non-adhesive surface 120, thereby attaching the membrane 20 to the workpiece 30. Specifically, the pressing mechanism 200 includes a pressing roller 210, the pressing roller 210 may be cylindrical, and the pressing roller 210 is located on a side of the carrier tape 100 where the non-adhesive surface 120 is located, for example, the pressing roller 210 may be located directly above the non-adhesive surface 120. When the film 20 is attached to the adhesive surface 110 of the carrier tape 100, the workpiece 30 is positioned right under the carrier tape 100 such that the attachment surface 21 of the film 20 is disposed toward the surface of the workpiece 30, and then the driver drives the pressing roller 210 such that the pressing roller 210 rolls on the non-adhesive surface 120 of the carrier tape 100, and at the same time, the pressing roller 210 applies a certain pressure downward, and finally the film 20 is attached to the product.
The number of the pressing rollers 210 may be one, and when the pressing rollers 210 roll from one end of the membrane 20 to the other end of the membrane 20, the membrane 20 may be attached to the workpiece 30 to form a film-attached product. The number of the pressing rollers 210 may be plural, for example, the number of the pressing rollers 210 may be two or more, and the plural pressing rollers 210 may be arranged at intervals along the length direction of the film 20, that is, adjacent two pressing rollers 210 do not contact with each other and have a gap, and of course, the surfaces of adjacent two pressing rollers 210 may contact with each other, so that the two pressing rollers 210 circumscribe each other. Compared with one pressing roller 210, for a plurality of pressing rollers 210, after the film 20 is attached to the workpiece 30 to form a film-attached product, the rolling stroke of each pressing roller 210 can be relatively reduced.
Of course, the viscosity of the pasting surface 21 of the film 20 is greater than that of the adhesive surface 110 of the carrier tape 100, in other words, the viscosity of the pasting surface 21 is relatively strong, and the viscosity of the adhesive surface 110 is relatively weak, when the workpiece 30 with the film 20 attached thereto is taken away by the manipulator, the adhesion between the film 20 and the workpiece 30 is significantly greater than that between the film 20 and the carrier tape 100, so that the film 20 is adhered to the workpiece 30 and taken away by the manipulator together with the workpiece 30, thereby avoiding the phenomenon that the film 20 is still adhered to the carrier tape 100 and cannot be taken away along with the workpiece 30, and finally ensuring that the workpiece 30 is smoothly pasted to form a pasted film product.
The cleaning mechanism 300 includes a first cleaning roller 310, the first cleaning roller 310 being located on a side of the adhesive surface 110, e.g., the first cleaning roller 310 being located directly below the adhesive surface 110. The first cleaning roller 310 may also have a cylindrical shape, a side circumferential surface of the first cleaning roller 310 is a first adhesive surface 311, and the viscosity of the first adhesive surface 311 is greater than that of the adhesive surface 110. The first cleaning roller 310 can be driven by a driver to roll on the adhesive surface 110 of the carrier tape 100, so that the first adhesive surface 311 is circumscribed with the adhesive surface 110. In the continuous lamination process of the carrier tape 100, when a certain number of film sheets 20 are continuously attached to the carrier tape 100, contaminants such as dust are adsorbed on the adhesive surface 110 of the carrier tape 100, and the contaminants are derived from two sources, namely, dust from air and the whole automatic lamination device 10, and dust from the non-adhesive surface 21 of the film sheet 20.
If the first cleaning roller 310 is not provided, when contaminants such as dust on the adhesive surface 110 are accumulated to a certain extent, the viscosity of the adhesive surface 110 is reduced, that is, the service life of the carrier tape 100 is reduced, so that the carrier tape 100 cannot firmly adsorb the film 20, which affects the adhesion precision between the film 20 and the workpiece 30, and even more, when the contaminants are continuously increased to cause the viscosity of the adhesive surface 110 to be continuously reduced, the carrier tape 100 cannot adsorb the film 20 and fails, and at this time, the entire automatic film laminating apparatus 10 cannot work. Therefore, when the contaminant causes the viscosity of the adhesive face 110 to drop to a certain value, the entire carrier tape 100 must be discarded and a new carrier tape 100 must be mounted again. This has at least two undesirable consequences: one is to affect the production efficiency of the adhesive film, specifically, for the service life of the carrier tape 100, it is generally out of service after about seven thousand sheets of film 20 are continuously attached, so that a new carrier tape 100 needs to be replaced, when the design productivity of the automatic adhesive film device 10 for attaching the film 20 is five seconds/sheet, if the total working time of one day is calculated according to white shift and night shift, at least two carrier tapes 100 need to be replaced each day, and the replacement time of each carrier tape 100 is about fifteen minutes, so that the time wasted by replacing the carrier tape 100 each day is thirty minutes, which finally affects the production efficiency of the adhesive film. And secondly, the production cost is improved, specifically, the cost of each carrier tape 100 is about seventy yuan, at least two carrier tapes 100 are wasted every day, the carrier tapes are calculated according to twenty-five working days every month, and the cost of the carrier tapes 100 wasted in one year is about fifty ten thousand yuan for ten automatic film sticking devices 10.
In the first embodiment, by arranging the first cleaning roller 310, since the viscosity of the first adhesion surface 311 is greater than the viscosity of the adhesion surface 110, when the first cleaning roller 310 rolls on the adhesion surface 110 of the carrier tape 100, the contaminants adsorbed on the adhesion surface 110 are transferred and adsorbed on the first adhesion surface 311, so that the first cleaning roller 310 cleans the adhesion surface 110 of the carrier tape 100, thereby eliminating the influence of the contaminants on the service life of the carrier tape 100, avoiding the waste of time and cost caused by frequently replacing the carrier tape 100, and reducing the manufacturing cost of products formed by the film-attached workpieces 30 on the basis of improving the working efficiency. According to the actual needs, the first cleaning roller 310 may clean the adhesive surface 110 of the carrier tape 100 at a set frequency, for example, the adhesive surface 110 may be cleaned three times or four times a day, and after the first cleaning roller 310 cleans the carrier tape 100, the first cleaning roller 310 may be unloaded to clean the carrier tape 100 during the operation of the carrier tape 100, so as to remove the contaminants adsorbed on the first cleaning roller 310, improve the cleanliness of the first adhesive surface 311, prevent the contaminants of the first adhesive surface 311 from secondarily contaminating the adhesive surface 110 during the cleaning of the carrier tape 100, and further improve the cleaning effect of the first cleaning roller 310. Obviously, in the process of detaching the first cleaning roller 310 for cleaning, the process does not have any influence on the work of the carrier tape 100, i.e., the cleaning of the first cleaning roller 310 and the film application of the workpiece 30 do not interfere with each other and conflict with each other, so that the automatic film application device 10 can continuously apply the film, and the cleaning of the first cleaning roller 310 is prevented from adversely affecting the working efficiency of the automatic film application device 10.
The automatic film sticking apparatus 10 further includes a first fixing member 410 and a second fixing member 420. The first fixing member 410 and the second fixing member 420 are spaced apart from each other in a direction in which the carrier tape 100 extends, for example, the first fixing member 410 is connected to one end of the carrier tape 100, and the second fixing member 420 is connected to the other end of the carrier tape 100. The carrier tape 100 is fixed by both the first fixing member 410 and the second fixing member 420, so that the carrier tape 100 is positioned directly above the workpiece 30, so that the carrier tape 100 attaches the film 20 to the workpiece 30.
When the automatic film laminating device 10 provided by the first embodiment is used for laminating a film on a workpiece 30, the film laminating method of the first embodiment can be formed, and referring to fig. 4, the film laminating method mainly includes the following steps:
s410, in the first step, the film sheet 20 is adsorbed by the adhesive surface 110 of the carrier tape 100. Specifically, both ends of the carrier tape 100 are fixed by both the first fixing member 410 and the second fixing member 420, respectively, so that the carrier tape 100 is positioned directly above the workpiece 30. The non-adhesive surface 21 of the film 20 is attached to the adhesive surface 110 of the carrier tape 100 so that the carrier tape 100 adsorbs the film 20. Of course, the film 20 has an adhesive surface 21 to be adhered to the work 30, and the viscosity of the adhesive surface 21 is higher than that of the adhesive surface 110.
S420, a second step, applying a force to the non-adhesive surface 120 of the carrier tape 100 to attach the film 20 to the workpiece 30. Specifically, the columnar pressing roller 210 rolls on the non-adhesive surface 120 of the carrier tape 100, and the pressing roller 210 applies a downward force to the carrier tape 100, so that the adhesive surface 21 of the film sheet 20 is adhered to the surface of the work 30, and the adhesion between the film sheet 20 and the work 30 is finally achieved. When the workpiece 30 is removed by the robot, since the viscosity of the sticking surface 21 is higher than that of the adhesive surface 110, the diaphragm 20 is attracted to the workpiece 30 to follow the workpiece 30 while being removed by the robot.
And S430, in the third step, providing the first cleaning roller 310 with a first adhesive surface 311, wherein the viscosity of the first adhesive surface 311 is greater than that of the adhesive surface 110, so that the first cleaning roller 310 rolls on the adhesive surface 110, and the first adhesive surface 311 is tangent to the adhesive surface 110 and adsorbs pollutants on the adhesive surface 110. After the first cleaning roller 310 removes the contaminants on the adhesive surface 110, the cleaning of the adhesive surface 110 can be realized, the service life of the carrier tape 100 is prolonged, the adhesive surface 110 always maintains reasonable viscosity to stably adsorb the diaphragm 20, the attachment precision between the diaphragm 20 and the workpiece 30 is ensured, and the manufacturing cost of a product formed by attaching the workpiece 30 to a film is reduced on the basis of improving the working efficiency.
Second embodiment
Referring to fig. 3, the automatic film laminating apparatus 10 includes a carrier tape 100, a pressing mechanism 200, and a cleaning mechanism 300. Carrier tape 100 has adhesive side 110 and non-adhesive side 120, with both adhesive side 110 and non-adhesive side 120 oriented exactly opposite, and obviously, non-adhesive side 120 is not tacky. The carrier tape 100 is used for adsorbing the film 20 and attaching the film 20 to the work 30, and specifically, the film 20 has an adhesive surface 21 and a non-adhesive surface 21, and the adhesive surface 21 and the non-adhesive surface 21 are opposite in orientation, and it is obvious that the non-adhesive surface 21 does not have viscosity. The non-adhesive side 21 of the film 20 is attached to the adhesive side 110 of the carrier tape 100, and the adhesive side 21 of the film 20 may be attached to the surface of the product when pressure is applied to the carrier tape 100, thereby attaching the film 20 to the work 30.
The pressing mechanism 200 is used to apply a force to the non-adhesive surface 120, thereby attaching the membrane 20 to the workpiece 30. Specifically, the pressing mechanism 200 includes a pressing roller 210, the pressing roller 210 may be cylindrical, and the pressing roller 210 is located on a side of the carrier tape 100 where the non-adhesive surface 120 is located, for example, the pressing roller 210 may be located directly above the non-adhesive surface 120. When the film 20 is attached to the adhesive surface 110 of the carrier tape 100, the workpiece 30 is positioned right under the carrier tape 100 such that the attachment surface 21 of the film 20 is disposed toward the surface of the workpiece 30, and then the driver drives the pressing roller 210 such that the pressing roller 210 rolls on the non-adhesive surface 120 of the carrier tape 100, and at the same time, the pressing roller 210 applies a certain pressure downward, and finally the film 20 is attached to the product. The number of the pressing rollers 210 may be one, and when the pressing rollers 210 roll from one end of the membrane 20 to the other end of the membrane 20, the membrane 20 may be attached to the workpiece 30 to form a film-attached product.
Of course, the viscosity of the pasting surface 21 of the film 20 is greater than that of the adhesive surface 110 of the carrier tape 100, in other words, the viscosity of the pasting surface 21 is relatively strong, and the viscosity of the adhesive surface 110 is relatively weak, when the workpiece 30 with the film 20 attached thereto is taken away by the manipulator, the adhesion between the film 20 and the workpiece 30 is significantly greater than that between the film 20 and the carrier tape 100, so that the film 20 is adhered to the workpiece 30 and taken away by the manipulator together with the workpiece 30, thereby avoiding the phenomenon that the film 20 is still adhered to the carrier tape 100 and cannot be taken away along with the workpiece 30, and finally ensuring that the workpiece 30 is smoothly pasted to form a pasted film product.
The cleaning mechanism 300 includes a first cleaning roller 310 and a second cleaning roller 320, both the first cleaning roller 310 and the second cleaning roller 320 being located on a side of the adhesive surface 110, e.g., the first cleaning roller 310 is located directly below the adhesive surface 110. The second cleaning roller 320 is further away from the carrier tape 100 than the first cleaning roller 310, for example, the second cleaning roller 320 is located directly below the first cleaning roller 310. The first cleaning roller 310 may also have a cylindrical shape, a side circumferential surface of the first cleaning roller 310 is a first adhesive surface 311, and the viscosity of the first adhesive surface 311 is greater than that of the adhesive surface 110. The first cleaning roller 310 can be driven by a driver to roll on the adhesive surface 110 of the carrier tape 100, so that the first adhesive surface 311 is circumscribed with the adhesive surface 110. In the continuous lamination process of the carrier tape 100, when a certain number of film sheets 20 are continuously attached to the carrier tape 100, contaminants such as dust are adsorbed on the adhesive surface 110 of the carrier tape 100, and the contaminants are derived from two sources, namely, dust from air and the whole automatic lamination device 10, and dust from the non-adhesive surface 21 of the film sheet 20.
The second cleaning roller 320 may be cylindrical, a side circumferential surface of the second cleaning roller 320 is a second adhesive surface 321, a viscosity of the second adhesive surface 321 is greater than a viscosity of the first adhesive surface 311, and the first cleaning roller 310 and the second cleaning roller 320 are coupled to each other such that the first adhesive surface 311 and the second adhesive surface 321 are in a circumscribed relationship with each other. The pressing roller 210, the first cleaning roller 310 and the second cleaning roller 320 are all flexible rollers, so that mutual collision in the working process can be reduced, the service lives of the pressing roller 210, the first cleaning roller 310 and the second cleaning roller 320 are prolonged, and the influence of collision impact force on the workpiece 30 is avoided.
If the first cleaning roller 310 is not provided, when contaminants such as dust on the adhesive surface 110 are accumulated to a certain extent, the viscosity of the adhesive surface 110 is reduced, that is, the service life of the carrier tape 100 is reduced, so that the carrier tape 100 cannot firmly adsorb the film 20, which affects the adhesion precision between the film 20 and the workpiece 30, and further, when the contaminants are continuously increased to cause the viscosity of the adhesive surface 110 to be continuously reduced, the carrier tape 100 cannot adsorb the film 20 and fails, and at this time, the entire automatic film laminating apparatus 10 cannot work. Therefore, when the contaminant causes the viscosity of the adhesive face 110 to drop to a certain value, the entire carrier tape 100 must be discarded and a new carrier tape 100 must be mounted again. This has at least two undesirable consequences: one is to affect the production efficiency of the adhesive film, specifically, for the service life of the carrier tape 100, it is generally out of service after about seven thousand sheets of film 20 are continuously attached, so that a new carrier tape 100 needs to be replaced, when the design productivity of the automatic film sticking device 10 for attaching the film 20 is five seconds/sheet, if the total working time of one day is calculated according to white shift and night shift, two carrier tapes 100 need to be replaced every day, and the replacement time of each carrier tape 100 is about fifteen minutes, so that the time wasted by replacing the carrier tape 100 every day is thirty minutes, which finally affects the production efficiency of the adhesive film. And secondly, the production cost is improved, specifically, the cost of each carrier tape 100 is about seventy yuan, at least two carrier tapes 100 are wasted every day, the carrier tapes are calculated according to twenty-five working days every month, and the cost of the carrier tapes 100 wasted in one year is about fifty ten thousand yuan for ten automatic film sticking devices 10.
In the second embodiment, the first cleaning roller 310 is arranged, and since the viscosity of the first adhesion surface 311 is greater than that of the adhesion surface 110, when the first cleaning roller 310 rolls on the adhesion surface 110 of the carrier tape 100, the contaminants adsorbed on the adhesion surface 110 are transferred and adsorbed on the first adhesion surface 311, so that the first cleaning roller 310 cleans the adhesion surface 110 of the carrier tape 100, thereby eliminating the influence of the contaminants on the service life of the carrier tape 100, avoiding the waste of time and cost caused by frequent replacement of the carrier tape 100, and reducing the manufacturing cost of products formed by the film-attached workpieces 30 on the basis of improving the working efficiency. The first cleaning roller 310 may be caused to clean the adhesive surface 110 of the carrier tape 100 at a set frequency according to actual needs, for example, the adhesive surface 110 may be cleaned three or four times a day.
Since the second cleaning roller 320 is further provided in the second embodiment, when the first cleaning roller 310 rolls on the adhesive surface 110 to adsorb the contaminants on the adhesive surface 110 to the first adhesive surface 311, the second cleaning roller 320 also rolls relative to the first cleaning roller 310, and since the viscosity of the second adhesive surface 321 is greater than that of the first adhesive surface 311, the contaminants adsorbed to the first adhesive surface 311 will be further adsorbed to the second adhesive surface 321, so that the second cleaning roller 320 cleans the first adhesive surface 311 of the first cleaning roller 310, and prevents the contaminants on the first adhesive surface 311 from forming secondary contamination on the adhesive surface 110 during the cleaning process of the carrier tape 100. When the contamination on the second adhesive surface 321 reaches a certain amount, the second cleaning roller 320 may be detached separately and the second adhesive surface 321 may be cleaned to remove the contamination on the second adhesive surface 321. In the process of cleaning the second cleaning roller 320, neither the carrier tape 100 nor the first cleaning roller 310 is affected in the process of filming the workpiece 30, thereby further improving the working efficiency of the automatic filming device 10.
The diameter of the second cleaning roller 320 is greater than or equal to twice the diameter of the first cleaning roller 310 so that the area of the second adhesive surface 321 is much greater than the area of the first adhesive surface 311. When the contaminants are adsorbed on the second adhesive surface 321, the distribution density of the contaminants on the second adhesive surface 321 may be reduced, thereby reducing the frequency of disassembling the second cleaning roller 320 for cleaning. Moreover, the second cleaning roller 320 forms a certain clamping force on the first cleaning roller 310 together with the carrier tape 100, so that the rolling smoothness of the first cleaning roller 310 on the adhesive surface 110 can be improved, the vibration generated by the first cleaning roller 310 in the rolling process is reduced, the first cleaning roller 310 is ensured to be in stable contact with the adhesive surface 110 all the time, and finally the cleaning effect of the first cleaning roller 310 on the adhesive surface 110 is improved.
The automatic film sticking apparatus 10 further includes a first fixing member 410 and a second fixing member 420. The first fixing member 410 and the second fixing member 420 are spaced apart from each other in a direction in which the carrier tape 100 extends, for example, the first fixing member 410 is connected to one end of the carrier tape 100, and the second fixing member 420 is connected to the other end of the carrier tape 100. The carrier tape 100 is fixed by both the first fixing member 410 and the second fixing member 420, so that the carrier tape 100 is positioned directly above the workpiece 30, so that the carrier tape 100 attaches the film 20 to the workpiece 30.
When the automatic film laminating device 10 provided by the second embodiment is used for laminating a film on a workpiece 30, the film laminating method of the second embodiment can be formed, and referring to fig. 5, the film laminating method mainly includes the following steps:
s510, in the first step, the film sheet 20 is adsorbed by the adhesive surface 110 of the carrier tape 100. Specifically, both ends of the carrier tape 100 are fixed by both the first fixing member 410 and the second fixing member 420, respectively, so that the carrier tape 100 is positioned directly above the workpiece 30. The non-adhesive surface 21 of the film 20 is attached to the adhesive surface 110 of the carrier tape 100 so that the carrier tape 100 adsorbs the film 20. Of course, the film 20 has an adhesive surface 21 to be adhered to the work 30, and the viscosity of the adhesive surface 21 is higher than that of the adhesive surface 110.
S520, in the second step, a force is applied to the non-adhesive surface 120 of the carrier tape 100 to attach the film 20 to the workpiece 30. Specifically, the columnar pressing roller 210 rolls on the non-adhesive surface 120 of the carrier tape 100, and the pressing roller 210 applies a downward force to the carrier tape 100, so that the adhesive surface 21 of the film sheet 20 is adhered to the surface of the work 30, and the adhesion between the film sheet 20 and the work 30 is finally achieved. When the workpiece 30 is removed by the robot, since the viscosity of the sticking surface 21 is higher than that of the adhesive surface 110, the diaphragm 20 is attracted to the workpiece 30 to follow the workpiece 30 while being removed by the robot.
S530, in the third step, a first cleaning roller 310 having a first adhesive surface 311 and a second cleaning roller 320 having a second adhesive surface 321 are provided, the viscosity of the first adhesive surface 311 is greater than that of the adhesive surface 110, the first cleaning roller 310 is made to roll on the adhesive surface 110, and the first adhesive surface 311 is tangent to the adhesive surface 110 and adsorbs contaminants on the adhesive surface 110. The viscosity of the second adhesive surface 321 is greater than that of the first adhesive surface 311, so that the second cleaning roller 320 is coupled to the first cleaning roller 310, and the second adhesive surface 321 circumscribes the first adhesive surface 311 and adsorbs contaminants on the first adhesive surface 311. Specifically, the first cleaning roller 310 is rolled on the adhesive surface 110, and the first adhesive surface 311 is tangent to the adhesive surface 110 and adsorbs contaminants on the adhesive surface 110. After the first cleaning roller 310 removes the contaminants on the adhesive surface 110, the cleaning of the adhesive surface 110 can be realized, the service life of the carrier tape 100 is prolonged, the adhesive surface 110 always maintains reasonable viscosity to stably adsorb the diaphragm 20, the attachment precision between the diaphragm 20 and the workpiece 30 is ensured, and the manufacturing cost of a product formed by attaching the workpiece 30 to a film is reduced on the basis of improving the working efficiency. Meanwhile, the second adhesive surface 321 adsorbs the contaminants on the first adhesive surface 311, so that the first cleaning roller 310 is cleaned, the contaminants on the first adhesive surface 311 are prevented from secondarily contaminating the adhesive surface 110, and the service life of the carrier tape 100 is further prolonged.
