[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] like Figure 1-10 As shown, a protective film coating device for automobile cosmetic mirror production includes a frame 1, on which are provided:

[0035] A loading chamber 155 for receiving the protective film;

[0036] The membrane covering assembly includes a transporter 121, on which an elastic membrane 123 is located in the center and air holes 122 are distributed around the elastic membrane 123, wherein:

[0037] The transporter 121 moves downward and is close to the protective film inside the loading chamber 155. Negative pressure is generated inside the transporter 121 so that the protective film is fixed on the air hole 122 by atmospheric pressure. The transporter 121 flips over and moves upward. The high-pressure gas inside the transporter 121 pushes the elastic film 123 to expand outward and push the protective film to fit the makeup mirror.

[0038] Specifically, the internal movement of the feeding chamber 155 is provided with a push plate for pushing the protective film, and a spring is provided between the push plate and the frame 1; when laminating, the sunshade is placed on the frame 1, and the makeup mirror on the sunshade is facing the feeding chamber 155, and the transporter 121 moves down and is tightly attached to the top protective film in the feeding chamber 155. At this time, negative pressure is generated in the transporter 121, and air needs to be inhaled from the air hole 122, and the air hole 122 is tightly attached to the protective film, and the atmosphere pushes the top protective film into the air hole 122. The membrane is pressed on the transporter 121. At this time, the transporter 121 moves up and rotates with the protective membrane, so that the protective membrane faces the makeup mirror. When the protective membrane contacts the makeup mirror, high-pressure gas is generated inside the transporter 121, causing the elastic membrane 123 to expand outward, pushing the protective membrane closer to the makeup mirror from the center, so that the protective membrane sticks to the makeup mirror. At the same time, the air hole 122 also sprays outward to separate the protective membrane from the transporter 121. After the makeup mirror is affixed with the protective membrane, the makeup mirror is protected by the protective membrane and can be better kept clean.

[0039] Furthermore, in the above embodiment, an electric telescopic rod may be provided on the frame 1, a motor may be provided on the output end of the electric telescopic rod, and a transporter 121 may be provided on the output end of the motor. After the protective film is fixed on the transporter 121, the electric telescopic rod extends to drive the transporter 121 to move upward. At this time, the motor drives the transporter 121 and the protective film thereon to rotate so that the protective film faces the makeup mirror. Other structures that can be obtained by those skilled in the art based on common technical knowledge are also possible.

[0040] In the above technical solution, when laminating, the sun visor is placed on the frame 1, and the makeup mirror on the sun visor is facing the loading chamber 155, and the transporter 121 moves down and is tightly attached to the uppermost protective film in the loading chamber 155. At this time, negative pressure is generated in the transporter 121, and air needs to be inhaled from the air hole 122, and the air hole 122 is tightly attached to the protective film. The atmosphere presses the uppermost protective film on the transporter 121. At this time, the transporter 121 moves up and rotates with the protective film so that the protective film faces the makeup mirror. When the protective film contacts the makeup mirror, high-pressure gas is generated inside the transporter 121, causing the elastic membrane 123 to expand outward, pushing the protective film closer to the makeup mirror from the center, so that the protective film is attached to the makeup mirror. At the same time, the air hole 122 also sprays outward to separate the protective film from the transporter 121. After the makeup mirror is attached with the protective film, the makeup mirror is protected by the protective film and can be better kept clean.

[0041] As an embodiment further provided by the present invention, a lower hopper 153 for carrying a sun visor with a makeup mirror and symmetrically distributed movable belts 151 are provided on the frame 1, and a plurality of transfer components for transferring the sun visor inside the lower hopper 153 are provided between the two movable belts 151.

[0042] Specifically, a driving roller for driving the movable belt 151 to move is provided on the frame 1, and the driving roller is driven by a motor.

[0043] Furthermore, when the film is being applied, the driving roller drives the movable belt 151 and the transfer assembly on the movable belt 151 to move along the frame 1. When the transfer assembly passes through the lower hopper 153, the sunshade at the bottom of the lower hopper 153 falls into the transfer assembly and is brought to the coating assembly by the transfer assembly, so that the coating assembly can perform the coating operation on the makeup mirror on the sunshade.

[0044] As another embodiment further provided by the present invention, the transfer assembly includes two pallets 112 movably mounted on the movable belt 151, and the pallets 112 are provided with stop blocks 113 and movable blocks 114 for supporting both sides of the light shielding plate, and the frame 1 is provided with a top plate 154 for pushing the light shielding plate.

[0045] Specifically, the transfer assembly includes a mounting plate 111 fixedly mounted on the movable belt 151, a support plate 112 is slidingly arranged on the mounting plate 111, a spring is arranged between the support plate 112 and the mounting plate 111, a push block 116 for pushing the movable block 114 to move is arranged on the support plate 112, a spring is arranged between the push block 116 and the support plate 112, and a wedge block 115 for pushing the push block 116 is arranged on the mounting plate 111.

[0046] Furthermore, when the transfer assembly passes through the lower hopper 153, the wedge block 115 on the mounting plate 111 is pushed by the lower hopper 153 and moves toward the inside of the mounting plate 111, pushing the push block 116 to move the movable block 114 toward the inside of the support plate 112, so that the movable block 114 retracts into the support plate 112. At this time, the support plate 112 is fixed on the mounting plate 111 by the wedge block 115, and the mounting plate 111 continues to move. The stop block 113 on the support plate 112 pushes the light shielding plate close to the top plate 154, so that the light shielding plate moves synchronously with the support plate 112. After the transfer assembly leaves the lower hopper 153, the push block 116 is pushed upward by the spring, and the movable block 114 extends out of the support plate 112 and rests on the side wall of the light shielding plate to fix the light shielding plate. At the same time, the wedge block 115 separates from the support plate 112 and retracts into the mounting plate 111. The support plate 112 can move relative to the mounting plate 111 with the light shielding plate.

[0047] As another embodiment further provided by the present invention, a water mist chamber 16 is provided on the frame 1, and a sealing plate 156 for closing the channel between the loading chamber 155 and the water mist chamber 16 is symmetrically provided on the frame 1, and the transporter 121 is movably installed inside the water mist chamber 16.

[0048] Specifically, the sealing plate 156 is provided with a slope for guiding the water flow. When the water mist condenses into water droplets and falls on the sealing plate 156, the water droplets will be guided out of the water mist chamber 16 by the slope on the sealing plate 156 to prevent the water droplets from entering the feeding chamber 155. A water mist injector is provided on the inner wall of the water mist chamber 16.

[0049] Furthermore, when the transporter 121 needs to take the protective film, the two sealing plates 156 move to open the loading chamber 155. At this time, the transporter 121 can take the protective film from the loading chamber 155. After the taking work is completed, the transporter 121 moves up and the sealing plate 156 re-seals the loading chamber 155. At this time, the protective film is in the water mist chamber 16, and the water mist in the water mist chamber 16 will adhere to the protective film so that the protective film can fit on the makeup mirror.

[0050] As another embodiment further provided by the present invention, the interior of the water mist chamber 16 is provided with a first movable sleeve 141 and a second movable sleeve 142 that are interlocked, a connecting pipe 144 is provided between the first movable sleeve 141 and the transporter 121, and the second movable sleeve 142 is provided with a cylindrical tenon block 143 extending into the interior of the water mist chamber 16.

[0051] Specifically, the cavity inside the first movable sleeve 141 is communicated with the cavity inside the second movable sleeve 142 , a tenon groove adapted to the cylindrical tenon block 143 is opened inside the water mist chamber 16 , and the connecting pipe 144 is rotatably mounted on the first movable sleeve 141 .

[0052] Furthermore, when the transporter 121 moves downward, the transporter 121 drives the first movable sleeve 141 to move downward relative to the second movable sleeve 142 through the connecting tube 144. The internal space of the first movable sleeve 141 and the second movable sleeve 142 increases, and air is sucked in from the transporter 121. Negative pressure is generated inside the transporter 121, so that the transporter 121 can transport the protective film.

[0053] As another embodiment further provided by the present invention, a first blocking block 145 for controlling the on / off of the connecting pipe 144 is provided, a one-way valve and a second blocking block 146 for controlling the on / off of the one-way valve are provided on the second movable sleeve 142, and a baffle 147 cooperating with the second blocking block 146 is provided inside the water mist chamber 16.

[0054] Specifically, a spring is provided between the first blocking block 145 and the connecting pipe 144 , and a spring is provided between the second blocking block 146 and the second movable sleeve 142 .

[0055] Furthermore, when the transporter 121 moves downward, the second blocking block 146 is pushed by the baffle 147, and the one-way valve of the second movable sleeve 142 is in an open state. The transporter 121 drives the first movable sleeve 141 to move downward relative to the second movable sleeve 142 through the connecting pipe 144. The internal space of the first movable sleeve 141 and the second movable sleeve 142 increases, and the air enters the second movable sleeve 142 through the one-way valve. The transporter 121 continues to move downward, the second blocking block 146 is separated from the baffle 147, and the one-way valve is closed by the second blocking block 146. The internal space of the first movable sleeve 141 and the second movable sleeve 142 increases. The space is further enlarged and the air is thin. At this time, the first blocking block 145 blocks the connecting pipe 144. When the transporter 121 contacts the protective film in the feeding chamber 155, the first blocking block 145 on the connecting pipe 144 is pushed by the inner wall of the water mist chamber 16. The connecting pipe 144 opens, and the first movable sleeve 141 sucks air from the transporter 121. Negative pressure is formed inside the transporter 121, and air needs to be sucked in from the air hole 122. The air hole 122 is tightly attached to the protective film. The atmosphere presses the uppermost protective film onto the transporter 121. Then the transporter 121 moves up, and the first blocking block 145 contacts the water mist chamber 16. The inner wall of the mist chamber 16 is separated, the connecting pipe 144 is blocked, the negative pressure inside the transporter 121 is maintained, the transporter 121 moves up and rotates, the internal space of the first movable sleeve 141 and the second movable sleeve 142 is reduced, the internal air pressure increases, the cylindrical tenon 143 on the second movable sleeve 142 moves along the tenon groove on the inner wall of the water mist chamber 16, the transporter 121 rotates, and the connecting pipe 144 rotates relative to the first movable sleeve 141. When the transporter 121 approaches the makeup mirror on the sun visor, the first blocking block 145 on the connecting pipe 144 is pushed by the inner wall of the top of the water mist chamber 16, and the connecting pipe 144 When opened, the air inside the first movable cover 141 and the second movable cover 142 flows into the transporter 121 through the connecting tube 144. The air pressure inside the transporter 121 increases, pushing the elastic membrane 123 to expand outward, pushing the protective membrane from the center to the makeup mirror, so that the protective membrane sticks to the makeup mirror, and at the same time the air hole 122 also sprays outward to separate the protective membrane from the transporter 121. When the air hole 122 sprays air, it can blow away the water mist around the transporter 121, preventing the water mist from entering the transporter 121 through the air hole 122, and reducing the possibility of the water mist condensing into water droplets and accumulating inside the transporter 121.

[0056] As another embodiment further provided by the present invention, it also includes a driving assembly for driving the transporter 121 to move, and the driving assembly includes a driving disk 131 rotatably installed inside the water mist chamber 16, and the driving disk 131 rotates to make the transporter 121 move along a predetermined path.

[0057] Specifically, when the transporter 121 transports the protective film, the driving disk 131 rotates, driving the transporter 121 to move downward, and the protective film is pressed on the transporter 121 by the atmospheric pressure. The driving disk 131 continues to rotate, driving the transporter 121 and the protective film to move upward. Then the transporter 121 is flipped so that the protective film on it faces the makeup mirror. The driving disk 131 continues to rotate, driving the transporter 121 to move upward, and sticking the protective film to the makeup mirror.

[0058] As another embodiment further provided by the present invention, a slide rod 126 is slidingly provided inside the water mist chamber 16, a cylindrical pin rod is provided on the drive disk 131, a slide groove adapted to the pin rod is opened on the slide rod 126, and the transporter 121 is rotatably installed on the slide rod 126.

[0059] Specifically, when the transporter 121 transports the protective film, the driving disk 131 rotates, and the cylindrical pin rod on the driving disk 131 moves along the slide groove on the slide rod 126, and pushes the slide rod 126 to move up and down inside the water mist chamber 16, thereby driving the transporter 121 and the protective film on the transporter 121 to move.

[0060] As another embodiment further provided by the present invention, a limit block 124 is provided on the transporter 121, a chute adapted to the limit block 124 is opened inside the water mist chamber 16, and a notch for the limit block 124 to rotate is provided at the center of the chute.

[0061] Specifically, when the slide rod 126 moves with the transporter 121, the limit block 124 on the transporter 121 cooperates with the slide groove on the inner wall of the water mist chamber 16 to limit the rotation of the transporter 121, so that the transporter 121 remains horizontal. When the limit block 124 on the transporter 121 moves to the notch in the center of the slide groove, the transporter 121 can rotate relative to the slide rod 126 with the limit block 124. After rotating 180°, the limit block 124 is back to facing the slide groove on the water mist chamber 16, and the transporter 121 can continue to move in a horizontal state.

[0062] As another embodiment further provided by the present invention, a gear 125 is provided on the transporter 121, a tooth block 127 adapted to the gear 125 is provided inside the notch, and a slider 158 is provided inside the water mist chamber 16, which is located on the moving path of the gear 125 and is used to drive the sealing plate 156 to move.

[0063] Specifically, the frame 1 is provided with a supporting roller 134 for supporting the movable belt 151, the water mist chamber 16 is provided with a mounting plate 132 coaxially distributed with the driving plate 131, a torsion spring 133 is provided between the mounting plate 132 and the driving plate 131, a rotation damping for slowing down the rotation speed is provided between the driving plate 131 and the water mist chamber 16, a synchronous belt 135 is provided between the mounting plate 132 and the supporting roller 134, and a first locking block 136 for fixing the driving plate 131 is symmetrically provided on the frame 1, a spring is provided between the first locking block 136 and the frame 1, a second locking block 137 is provided on the first locking block 136, and a slope is provided on the side wall of the second locking block 137 close to the mounting plate 111, and an arc groove adapted to the second locking block 137 is provided on the stop block 113 and the movable block 114, and a rocker 157 is movably provided between the slider 158 and the sealing plate 156.

[0064] Furthermore, when the film is being applied, the driving roller drives the movable belt 151 and the transfer assembly on the movable belt 151 to move along the frame 1. When the transfer assembly passes through the lower hopper 153, the wedge block 115 on the mounting plate 111 is pushed by the lower hopper 153 and moves toward the inside of the mounting plate 111, pushing the push block 116 to move the movable block 114 toward the inside of the support plate 112, so that the movable block 114 is retracted into the support plate 112. At this time, the support plate 112 is fixed on the mounting plate 111 by the wedge block 115. The mounting plate 111 continues to move, and the stopper 113 on the support plate 112 pushes the light shielding plate close to the top plate 154, so that the light shielding plate and the support plate 112 move synchronously. After the transfer assembly leaves the lower hopper 153, the push block 116 is pushed upward by the spring, and the movable block 114 extends from the support plate 112 and abuts against the side wall of the light shielding plate to fix the light shielding plate. At the same time, the wedge block 115 separates from the support plate 112 and retracts into the mounting plate 111. The support plate 112 can move relative to the mounting plate 111 with the light shielding plate.

[0065] As the movable belt 151 moves, the movable belt 151 pushes the supporting roller 134 to rotate, and the supporting roller 134 drives the mounting plate 132 to rotate through the synchronous belt 135, thereby deflecting the torsion spring 133 and accumulating elastic potential energy.

[0066] When the supporting plate 112 and the sunshade are moved to above the laminating assembly, the movable block 114 and the stop block 113 move along the slope on the second locking block 137, so that the two second locking blocks 137 are respectively embedded in the arc grooves on the movable block 114 and the stop block 113. The second locking block 137 fixes the movable block 114 and the stop block 113, and then fixes the supporting plate 112 and the sunshade. At this time, the makeup mirror on the sunshade is facing each other, and the two second locking blocks 137 drive the two first locking blocks 136 to move, and the first locking blocks 136 are separated from the driving disk 131, and the driving disk 131 is unlocked;

[0067] The torsion spring 133 releases elastic potential energy, driving the driving disc 131 to rotate. The driving disc 131 rotates slowly under the action of the rotational damping. The cylindrical pin on the driving disc 131 moves along the slide groove on the slide rod 126, and pushes the slide rod 126 and the transporter 121 to move downward inside the water mist chamber 16. The transporter 121 moves vertically downward and maintains a horizontal state under the cooperation of the limit block 124 and the slide groove. The transporter 121 drives the first movable sleeve 141 relative to the second movable sleeve through the connecting pipe 144. The movable sleeve 142 moves downward, and the internal space of the first movable sleeve 141 and the second movable sleeve 142 increases, and the air becomes thinner. At this time, the first blocking block 145 blocks the connecting pipe 144, and the gear 125 pushes the slider 158 downward. The slider 158 pushes the sealing plate 156 to move through the rocker 157, and the feeding chamber 155 is opened. When the transporter 121 contacts the protective film in the feeding chamber 155, the first blocking block 145 on the connecting pipe 144 is pushed by the inner wall of the water mist chamber 16, and the connecting pipe 144 is opened. When the first movable sleeve 141 is opened, air is sucked from the transporter 121, and negative pressure is formed inside the transporter 121. Air needs to be sucked from the air hole 122, and the air hole 122 is tightly attached to the protective film. The atmosphere presses the uppermost protective film onto the transporter 121, and the driving disc 131 continues to rotate, driving the slide bar 126 and the transporter 121 to move upward. The first blocking block 145 is separated from the inner wall of the water mist chamber 16, and the connecting pipe 144 is blocked. The negative pressure inside the transporter 121 is maintained, and the limit block 124 is closed. When the gear 125 moves to the notch in the middle of the chute, it meshes with the tooth block 127 inside the chute. The gear 125 moves upward and is pushed by the tooth block 127. The gear 125 drives the transporter 121 and the limit block 124 to rotate 180 degrees relative to the slide bar 126, so that the protective film on the transporter 121 faces the makeup mirror. The spring pushes the slider 158 to move. The slider 158 pulls the sealing plate 156 to move through the rocker 157. The sealing plate 156 seals the feeding chamber 155 to reduce the entry of water mist into the feeding chamber 155.

[0068] The driving disc 131 continues to rotate, driving the transporter 121 to move upward. The internal space of the first movable sleeve 141 and the second movable sleeve 142 is reduced, and the internal air pressure thereof is increased. The cylindrical tenon block 143 on the second movable sleeve 142 moves along the tenon groove on the inner wall of the water mist chamber 16. The baffle 147 pushes the second blocking block 146 to open the one-way valve on the second movable sleeve 142. The connecting pipe 144 rotates relative to the first movable sleeve 141. The protective film moves in the water mist chamber 16 for a period of time. The water mist in the water mist chamber 16 will adhere to the protective film so that the protective film can fit the protective film. On the vanity mirror, when the transporter 121 approaches the vanity mirror on the sun visor, the first blocking block 145 on the connecting tube 144 is pushed against the inner wall of the top of the water mist chamber 16, causing the connecting tube 144 to open. The air inside the first and second movable sleeves 141, 142 flows through the connecting tube 144 into the transporter 121. The air pressure inside the transporter 121 increases, pushing the elastic membrane 123 outward to expand, pushing the protective membrane from the center toward the vanity mirror, causing the protective membrane to adhere to the vanity mirror. Simultaneously, the air holes 122 also release air outward, separating the protective membrane from the transporter 121.

[0069] The driving disc 131 continues to rotate, driving the transporter 121 downward. The transporter 121 drives the first movable sleeve 141 downward relative to the second movable sleeve 142 via the connecting tube 144. The internal space between the first movable sleeve 141 and the second movable sleeve 142 increases, and air enters the second movable sleeve 142 through the one-way valve. The transporter 121 continues to move downward and rotates to return to its initial position.

[0070] During this process, the movable belt 151 keeps the mounting plate 111 moving, and the spring between the mounting plate 111 and the supporting plate 112 is stretched. When the protective film on the makeup mirror is applied, the spring accumulates enough elastic potential energy to drive the supporting plate 112 to move. The two second locking blocks 137 respectively leave the arc grooves on the stop block 113 and the movable block 114, and the first locking block 136 is attached to the driving disk 131. When the transporter 121 returns to the initial position, the two first locking blocks 136 are synchronously inserted into the driving disk 131, locking the driving disk 131 and waiting for the next film application.

[0071] When the movable belt 151 moves downward with the mounting plate 111 , the light shielding plate is separated from the stop block 113 and the movable block 114 under the action of gravity and is separated from the production line.

[0072] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
