Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present invention.

The invention provides automatic film pasting equipment (hereinafter referred to as equipment for short), which is used for pasting a protective film on electronic products such as mobile phones, flat plates, intelligent wearable equipment and the like. The structure of the automatic film sticking equipment of the embodiment of the invention is described below by taking a product to be stuck with a film as an example, namely a mobile phone.

Referring to fig. 1, the apparatus may perform the following operations: firstly, selecting a mobile phone model and a diaphragm type on equipment (S101); cleaning the mobile phone (S102); automatically cutting the film (S103); removing the fine waste film (S104); attaching a membrane on the mobile phone and pressing the membrane tightly (S105); film edge pressing and UV baking curing (S106); removing the surface waste film (S107); the mobile phone is taken out (S108). The respective operation steps shown in fig. 1 will be described below with reference to the structures shown in fig. 2a to 13.

Fig. 2a is a schematic overall appearance diagram of an automatic film laminating apparatus 200 according to an embodiment of the present invention. Fig. 2b is a schematic perspective view of the internal structure of the automatic film laminating apparatus 200 according to the embodiment of the present invention. Fig. 2c is a schematic side view of the internal structure of the automatic film laminating apparatus 200 according to the embodiment of the present invention. Referring to fig. 2a, the device 200 comprises a housing 201. A touch display screen 202 is embedded in the housing 201, and the touch display screen 202 can be used for advertising, video playing and the like, and can also be used for model selection of a product to be filmed before filming (step S101 in fig. 1). The housing 201 is also provided with an inlet and outlet 203.

Referring to fig. 2b, the apparatus 200 includes a three-axis digitally controlled displacement mechanism including an X-axis guide 211, a Y-axis guide 212, and a Z-axis guide 213, each extending in three mutually perpendicular directions. The Z-axis guide 213 extends in the vertical direction, and the X-axis guide 211 and the Y-axis guide 212 extend in the horizontal direction and are perpendicular to each other. And a Z-axis sliding seat is arranged on a Z-axis lead screw of the Z-axis motor and is erected on a Z-axis guide rail 213. And a Y-axis guide rail 212 and a Y-axis motor are installed on the Z-axis slide seat, a Y-axis slide seat is erected on the Y-axis guide rail 212, and the Y-axis slide seat is connected with the Y-axis motor. An X-axis guide rail 211 and an X-axis motor are arranged on the Y-axis sliding seat.

Referring to fig. 2b and 2c, the apparatus 200 further includes a product placement mechanism 220 and an a-axis motion mechanism 310. The product placement mechanism 220 is used for loading a mobile phone to be filmed. The a-axis moving mechanism 310 can drive the product placing mechanism 220 to move along the direction parallel to the Y-axis guide rail 212, so that the product placing mechanism 220 can be pushed out of the housing 201 through the inlet/outlet 203, and at this time, the mobile phone can be placed on the product placing mechanism 220; then the a-axis moving mechanism 310 drives the product placing mechanism 220 to be pulled into the housing 201 through the inlet and outlet 203, and then cooperates with other mechanisms to complete the subsequent film pasting operation.

Fig. 3a is a schematic structural view of the a-axis movement mechanism 310 and the product placement mechanism 220 according to an embodiment of the present invention. Fig. 3b is a partially exploded detail schematic view of the product placement mechanism 220 of fig. 3 a. Referring to fig. 3a and 3b, the a-axis moving mechanism 310 is specifically composed of an a-axis guide rail 315, an a-axis lead screw 311, an a-axis driving motor 316 and other fixing components. The a-axis guide rails 315 are parallel to the Y-axis guide rails 212. An a-axis lead screw 311 and an a-axis driving motor 316 (e.g., a displacement driving motor) are connected to the a-axis guide 315, and the movable product placing mechanism 220 is driven by the a-axis driving motor 316 to run parallel to the Y-axis to enter and exit from the entrance 203.

The product placement mechanism 220 includes a tray 221 for placing products. The tray 221 is mounted on the a-axis guide 315. More specifically, as shown in FIG. 3b, the product placement mechanism 220 further includes a vacuum cup 222 for holding the handset in place. The product placement mechanism 220 further includes a clamp cylinder 223 and a clamp block 224 that is pushed by the clamp cylinder 223. The product placement mechanism 220 also includes a lift plate 225. The elevating plate 225 is installed on the front end of the tray 221. The tray 221 is also provided with left and right guide posts 226, left and right springs 227, guide posts 228 for supporting the left and right spring posts, and left and right rollers 229 below. The lifting plate 225 may have an L-shape extending along an edge of the tray 221. When the tray 221 is pushed out of the access opening 203, the lifting plate 225 is raised and protruded from the upper surface of the tray 221, and after the tray 221 is pulled into the access opening 203, the lifting plate 225 is lowered to expose the edge of the cellular phone.

When the device 200 of the present invention is used, the user can scan the two-dimensional code through the mobile phone and select the model on the mobile phone, or after selecting the corresponding model of the mobile phone through the touch display screen 202, the a-axis moving mechanism 310 drives the product placement mechanism 220 to extend out of the inlet/outlet 203. At this time, the L-shaped elevating plate 225 protrudes from the upper surface of the tray 221. The user places the phone on the tray 221 and places both edges of the phone against the L-shaped lift plate 225. At this time, the clamping cylinder 223 can push the clamping block 224 to clamp the mobile phone, and the two vacuum chucks 222 can suck the mobile phone. Since the cellular phone is clamped and fixed by the clamping block 224, cellular phones of different sizes can be placed on the tray 221. Then, the a-axis moving mechanism 310 drives the product placing mechanism 220 to slowly enter the apparatus 200 from the entrance 203, and when the roller 229 under the tray 221 touches the groove of the a-axis guide rail 315 during the entering process, the roller 229 pulls the spring guide post 228 and the lifting plate 225 to descend to expose the edge of the mobile phone. Thus, when the tray 221 is outside the device 200, the elevator plate 225 locates and secures the phone for the user; when the tray 221 enters the interior of the apparatus 200 for film application, the lifting plate 225 is pulled down by about 5 mm. Because the outer edge screen of the curved screen mobile phone is lower than the upper surface of the mobile phone screen, the outer edge screen of the curved screen mobile phone can be effectively wrapped by lowering the lifting plate 225. In addition, the subsequent operations of cleaning, film pasting and the like of other non-curved screen mobile phones are not influenced by lowering the lifting plate 225. Therefore, the problem of fitting of the curved screen is solved, and a user can be ensured to correctly place the mobile phone on the tray 221, so that the mobile phone is prevented from being damaged.

Further, as shown in fig. 4, a vision system is provided above the access opening 203. The vision system includes a vision camera 209. When the tray 221 is extended out of the access opening 203, the vision camera 209 may be lifted upward and used to photograph a human face. When the cell phone is placed into the tray 221, the tray 221 enters the access opening 203, the vision camera 209 may be flipped down and used to photograph the cell phone to confirm that the cell phone is properly positioned on the tray 221.

The apparatus 200 further includes a cleaning mechanism for cleaning and dusting the handset (step S102 in fig. 1). The cleaning mechanism specifically comprises a cleaning mechanism for cleaning and a dust adhering mechanism for adhering dust. Firstly, the cleaning mechanism is used for cleaning the mobile phone screen, and then the dust sticking mechanism is used for sticking dust on the mobile phone screen.

FIG. 5a is a combined view of a cleaning mechanism 250 and a dust binding mechanism 260, according to an embodiment of the present invention. Fig. 5b is a schematic structural diagram of a cleaning mechanism 250 according to an embodiment of the invention. As shown in fig. 2c, 5a and 5b, the cleaning mechanism 250 includes a clean cloth supply roll 251, a plurality of clean cloth tension rolls 252, a clean cloth supply roll 253, a cleaning head 254 suspended above an a-axis guide 315, a cleaning agent supply member having a cleaning agent storage tub 256 and a supply pipe 255, and a cleaning lift mechanism 257 (e.g., an air cylinder).

When the mobile phone is cleaned by the cleaning mechanism 250, the product placing mechanism 220 with the mobile phone is driven below the cleaning mechanism 250 by the a-axis moving mechanism 310, and the cleaning lifting mechanism 257 lowers the cleaning head 254 onto the screen of the mobile phone. The dust-free cloth is drawn from the dust-free cloth supply roll 251 to the dust-free cloth take-up roll 253 by the dust-free cloth tension wheel 252. The dust-free cloth is wound around the bottom of the cleaning head 254, and the liquid supply pipe 255 sprays the cleaning liquid from the cleaning liquid storage barrel 256 onto the dust-free cloth, and at the same time, the product placement mechanism 220 is driven by the a-axis movement mechanism 310 to carry the mobile phone to reciprocate below the cleaning head 254. Therefore, the surface of the mobile phone can be cleaned, and the process of wiping the screen of the mobile phone by holding the dustless cloth is simulated.

Referring to fig. 2C, 5a and 5C, the dust-binding mechanism 260 includes a dust-binding tape feeding roll 261, a plurality of dust-binding tape tensioning rolls 262, a dust-binding tape receiving roll 263, a dust-binding head 264 suspended above the a-axis guide 315, and a dust-binding lifting mechanism 265 (e.g., an air cylinder). The dust-binding adhesive paper is drawn from the dust-binding adhesive paper feeding roll 261 to the dust-binding adhesive paper receiving roll 263 through the dust-binding adhesive paper tension wheel 262, and the dust-binding adhesive paper is wound around the bottom of the dust-binding head 264.

After the mobile phone is wiped clean by the cleaning mechanism 250, and then the mobile phone is subjected to dust adhering operation by the dust adhering mechanism 260, at this time, the a-axis moving mechanism 310 moves the mobile phone to a position below the dust adhering head 264 of the dust adhering mechanism 260. The dust-sticking lifting mechanism 265 drives the dust-sticking head 264 and the dust-sticking adhesive tape to descend to the surface of the mobile phone, and the dust-sticking head 264 carries the mobile phone to reciprocate below the dust-sticking head 264 along the A-axis guide rail through the product placing mechanism 220 from one end of the mobile phone. Meanwhile, the dust collecting motor of the collecting roll drives the dust-binding adhesive paper collecting roll 263 to rotate to pull the dust-binding adhesive paper to operate, so that the dust on the screen can be bound by the dust-binding adhesive paper, and a user can feel like holding the dust-binding adhesive paper by hands to remove dust, filamentous substances and the like on the surface of the screen of the mobile phone. The dust-free cloth collecting roll 253 and the dust-binding adhesive paper collecting roll 263 are used for collecting dust-free cloth and dust-binding adhesive paper in the working process, and when the next mobile phone is cleaned, the brand new dust-free cloth and dust-binding adhesive paper are used.

As shown in connection with fig. 2c, the apparatus 200 includes multiple sets of

film supply mechanisms

610a, 610b, 610c, 610d, 610 e. Each set of film supply mechanisms 610a-610e may include a corresponding roll of film sheet stock 611a-611e, roll of film sheet stock 612a-612e, film cutting platforms 620a-620e, and film sheet separators 630a-630 e. Each set of film supply mechanisms 610a-610e may be mounted within the fuselage by a mounting bracket.

The film supplying mechanisms 610a-610e can be respectively used for placing films aiming at different types of mobile phones and films made of different materials. For example, a plurality of types of film sheets such as a frosted film, a high-definition film, a peep-proof film, a UV film, a mirror film, a diamond film, an AR film, a scratch-proof protective film, a 3D film, and the like can be set for the user to select. In fig. 2c 5 sets of film supply means 610a-610e are shown, each set of film supply means 610a-610e being located at a different level of height, respectively. However, the apparatus 200 may also have any other number of film supply mechanisms, such as having more than 5 sets of film supply mechanisms. Accordingly, the inventive apparatus 200 is not limited to providing 5 layers of membrane. With multiple film supply mechanisms, the apparatus 200 of the present invention may employ multiple types of films to be installed in the apparatus 200 for selection by the user.

Fig. 6 is a schematic structural diagram of a set of film supply mechanisms according to an embodiment of the invention. Since each set of film supply mechanisms may have a similar structure, the numerical reference numerals in fig. 6 may correspond to the same numerical reference numerals in fig. 2c, with no labeled suffix a-e distinguishing each set of film supply mechanisms. As shown in fig. 6, a set of film supply mechanisms 610 may include a film supply roll 611, a corresponding film take-up roll 612, a take-up motor 613, a film supply tension wheel 614 between the film supply roll 611 and the corresponding film take-up roll 612, a film cutting platform 620 between the film supply tension wheel 614 and the film take-up roll 612, and a film sheet separator 630 between the film cutting platform 620 and the film take-up roll 612.

As shown in fig. 6, the film web is drawn from the film web supply roll 611, past the film supply tension wheel 614, to the film cutting platform 620 where the film web is cut to form cut film webs. Because the membrane is composed of the membrane material and the release film which are mutually attached, the membrane material and the release film need to be separated before the mobile phone is attached with the membrane. After the membrane passes through the membrane cutting platform 620, the membrane is separated into a membrane material and a release membrane for sticking the membrane to the mobile phone by the membrane separator 630. The release film separated by the film separator 630 is finally drawn to the film roll 612.

The structure of the film cutting platform 620 and the operation process (step 103 in fig. 1) of automatically cutting the film by the film cutting platform 620 in cooperation with other components of the apparatus are described in detail below with reference to fig. 7a and 7 b.

Fig. 7a and 7b show an inverted view and a forward view, respectively, of the slitting station 620. Referring to fig. 7a and 7b, the film cutting platform 620 is mainly composed of the following components: 2 lower pressing plates 621 used for pressing the membrane, 1 platform 622 used for cutting the membrane, 4 linear bearings 623 used for balancing the upper part and the lower part of the supporting platform 622, 2 lower lifting limiting blocks 624 used for balancing the upper part and the lower part of the supporting platform 622, 2 air cylinders 625 used for balancing the upper part and the lower part of the supporting platform 622, 4 adjusting screws 626 used for adjusting the flatness of the platform 622, and 4 fixing screws 627 used for fixing the platform.

The film cutting platform 620 is one of the important mechanisms of the equipment, and has high requirement on flatness. After the film cutting platform 620 is installed, the flatness of the platform needs to be calibrated. The embodiment of the present invention adjusts the flatness of the platform 622 by adjusting the height of each angle of the platform 622 with four adjusting screws 626, and then locks the fixing screws 627.

When the membrane is cut, 2 cylinders 625 of the membrane cutting platform 620 can drive the two lower pressing plates 621 to compress the two side edges of the membrane, and after the membrane is cut, the 2 cylinders 625 drive the two lower pressing plates 621 to be lifted so that the membrane can be moved.

According to an embodiment of the present invention, the film sheet on the film cutting platform 620 is cut by a film cutting mechanism. Fig. 8a shows an assembled view of a slitting mechanism according to an embodiment of the invention positioned above a slitting platform. As shown in fig. 8a, the apparatus of the present invention further comprises a film cutting mechanism 710. The film cutting mechanism 710 is installed on the X-axis guide rail 211 and connected with an X-axis motor, and the film cutting mechanism 710 can be moved to the position above the film cutting platform 620 through a three-axis numerical control displacement mechanism. The film cutting mechanism 710 may have a cutting knife vertically moving in a direction perpendicular to the film cutting platform 620 to cut the film sheet.

Fig. 8b shows a schematic view of a film cutting mechanism 710 according to an embodiment of the invention. Referring to fig. 8b, the film cutting mechanism 710 has an alloy cutter 711 to cut the film sheet on the film cutting platform 620. The film cutting mechanism 710 also comprises a film cutting cylinder 712, a sliding block 713 and other fixing parts. The cutter 711 is installed on the slider 713 and is driven by the film cutting cylinder 712 to move in a vertical direction. The cutter 711 may be a one-use-one-standby cutter or a one-use-multiple-standby cutter. The backup cutters may reduce maintenance of the apparatus 200 due to the cutter life.

The film cutting operation may be performed by the film cutting mechanism 710 and the film cutting stage 620 (step S103 in fig. 1). As shown in fig. 8a and 8b, the film cutting mechanism 710 mounted on the X-axis guide rail 211 can be moved to be fed above the corresponding film cutting platform 620, the lower pressing plate 621 of the film cutting platform 620 can press the two sides of the film sheet, and the film cutting cylinder 712 of the film cutting mechanism 710 pushes the alloy cutting blade 711 to descend onto the film sheet. The three-axis numerical control displacement mechanism drives the film cutting mechanism 710 to move in the directions of an X axis, a Y axis and a Z axis so as to cut out a required film shape.

Due to the need for product lamination, fine waste films may be generated after the film cutting mechanism 710 cuts the film pieces. The fine waste films include, for example: the film comprises a headphone pore waste film, a camera pore waste film, an induction pore waste film, a fingerprint pore waste film and the like. After the film is cut, fine waste film is left on the film sheet and thus needs to be taken out. Therefore, in some embodiments, the apparatus of the present invention further comprises a fine waste film removing unit to perform an operation of removing the fine waste film (step S104 in fig. 1).

Referring to fig. 8b, a waste film removing unit 720 is installed between two cutters 711 of the film cutting mechanism 710. The fine waste film removing assembly 720 includes a removing needle disposed between two cutters 711, the removing needle 722 being shown in fig. 8 c. In addition, the fine waste film removing unit 720 may further include a cylinder and a gas valve. The air cylinder is connected to the removal needle 722 and serves to push the removal needle 722. The gas valve is connected to the removal needle 722 to introduce positive pressure gas into the removal needle 722. The fine waste film removing unit 720 is installed on the slider 713 and is operated in a vertical direction by an air cylinder.

The fine waste film removing assembly 720 is driven by the three-axis numerical control displacement mechanism to move in the directions of the X axis, the Y axis and the Z axis to reach the position of the fine waste film. The air cylinder pushes the removing needle 722 to remove the fine waste film on the membrane, and the removed fine waste film is stopped on the needle tip 723 of the removing needle 722. The three-axis numerical control displacement mechanism can drive the fine waste film removing assembly 720 to reach a waste film collecting position, and positive pressure gas is blown in through the gas valve to blow the fine waste film on the needle tip 723 away from the needle tip 723 of the removing needle 722.

After the film cutting and the fine waste film removal, the film material of the film sheet and the release film are separated by performing a film operation by a film separator 630 (fig. 6). Fig. 9 shows a schematic structural view of the membrane separator 630. As shown in fig. 9, the membrane separator 630 has: a first separation tension wheel 632 for tensioning the cut film sheet, a separation fan 631 for separating the film material of the film sheet from the release film, and a second separation tension wheel 633 for tensioning the separated release film. Accordingly, the height difference between the first and second

separating tension wheels

632 and 633 can be used to determine the angle of the tensioned release film and cut film sheet, and the output angle of the film sheet can be confirmed by adjusting the angle of the first separating tension wheel 632 by adjusting the two adjusting screws 634.

Referring to fig. 6 and 9, in the process of separating the cut film sheets by using the film separator 630, the film sheet material roll 612 pulls the film material to run, and the cut film sheets pass through the height difference between the film cutting platform 620 and the first separation tension wheel 632 installed below the film separator 630, that is, the cut film sheets are primarily separated by the bending angle of the appropriate film material. On the other hand, the film material collecting roll 612 draws the cut film to be tensioned and bent so as to primarily separate the film material from the release film, and then an airflow is generated from the bottom to the top against the primarily separated film material by using the axial flow wind of the separation fan 631 to separate the film material from the release film, thereby enhancing the release effect. The release film separated by the film separator 630 is finally drawn to the film roll 612.

In the membrane separation operation at the membrane separator 630, in addition to collecting the release film by the membrane roll 612, the apparatus of the present invention sucks the separated membrane material by the membrane suction mechanism for the membrane application to the mobile phone.

During the stepwise division of the membranes by the membrane separator 630, the film material is completely sucked onto the film adsorption web 812 by the siphon force of the two fans 811. The separated film material is blown onto the film adsorption net 812 of the film adsorption mechanism 810, so that the film material can be stably adsorbed, and the failure of releasing caused by adhesion of the film material and the release film again due to gravity can be avoided.

And then, the membrane material adsorbed by the membrane adsorption mechanism 810 is brought above the mobile phone by the three-axis numerical control displacement mechanism. The Z-axis mechanism lowers the film material and aligns to the cell phone location, and then presses the film on the cell phone by the film pressing wheel 815 (step S106 in fig. 1). Then the a-axis moving mechanism 310 drives the mobile phone to slowly run, and the film material is pasted on the mobile phone in a mode of simulating hand pasting. In the mode, the film pressing capacity is moderate, the film pressing wheel 815 made of soft materials is installed, the A-axis motion mechanism 310 runs stably, and the pasted film has no bubbles and is superior to manual film pasting.

In some embodiments, when the handset is a curved screen. After the film is attached, the a-axis moving mechanism 310 conveys the mobile phone to the lower part of the attaching and curing device 910, the cylinder 913 presses the attaching and curing device 910 down on the mobile phone, and the vacuum device (vacuum pump) performs vacuum pumping to tightly adsorb the film material on the curved screen of the mobile phone, so that the film is tightly attached to the surface and the edge of the mobile phone, and the attachment of the curved screen is completed.

After the mobile phone is pasted with the film, a layer of waste film is left on the surface of the mobile phone and needs to be removed. Therefore, as shown in fig. 2c and 12, the apparatus 200 further includes a waste film removing mechanism 920 to perform an operation of removing the waste film (step S107 in fig. 1).
