[0041] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0042] As described in the background art, during processing of the existing composite plate printing and coating device, oxygen, water vapor and other impurities in the air will react with the sputtered metal atoms, resulting in limitations in the color of the surface of the mobile phone back cover.

[0043] In order to solve this technical problem, the present invention provides a composite plate printing coating device, which is applied to the coating of the back cover of a mobile phone.

[0044] Specifically, please refer to Figure 1-Figure 10 The composite plate printing and coating device specifically includes a machine body 1, and also includes an evacuation mechanism 2 arranged in the machine body 1, a cleaning mechanism 3 arranged in the machine body 1, and an ejection mechanism 4 arranged in the machine body 1;

[0045] The vacuum mechanism 2 includes a vacuum chamber 201 disposed on the body 1, a driving assembly 210 disposed in the body 1, and a sealing assembly 211 disposed in the body 1;

[0046] The cleaning mechanism 3 comprises a hollow seat 301 disposed on the machine body 1, an inclined tube 302 fixedly passing through the hollow seat 301, and a fixing assembly 304 disposed in the machine body 1;

[0047] The ejection mechanism 4 includes a U-shaped block 401 disposed in the vacuum chamber 201 and a positioning assembly 402 disposed in the machine body 1 .

[0048] The composite plate printing and coating device provided by the present invention is designed to solve the problem in the prior art that oxygen, water vapor and other impurities in the air react with the sputtered metal atoms during processing, resulting in the color of the surface of the mobile phone back cover being limited. The present application provides an evacuation mechanism 2 and an ejection mechanism 4. The evacuation mechanism 2 allows the air inside the vacuum chamber 201 to be exhausted. After the electroplating process, the processed mobile phone back plate is rotated and ejected by the ejection mechanism 4, thereby realizing the electroplating process of the mobile phone back plate in a vacuum environment, and automatically discharging the material, which is convenient for the staff to take out.

[0049] By setting the cleaning mechanism 3, the vacuum chamber 201 is cleaned by the cleaning mechanism 3 when the cover plate 202 is unfolded, and the harmful gas generated during the processing of the mobile phone back plate is purified. When the cover plate 202 is rotated and closed, the cover plate 202 is squeezed by the cleaning mechanism 3, so that the cover plate 202 and the U-shaped block 401 fix the mobile phone back plate, which solves the problem of impurities and harmful gases generated during the processing of the mobile phone back plate in the prior art;

[0050] By setting up the vacuum mechanism 2, the cover plate 202 and the vacuum chamber 201 are air-cooled by the vacuum mechanism 2 when the cover plate 202 is unfolded, thereby achieving pre-cooling and solving the thermal stress caused by temperature changes in the prior art, which may cause the film layer on the back panel of the mobile phone to peel off or the base material to deform.

[0051] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0052] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0053] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0054] Example 1, please refer to Figure 2 , Figure 5 , Figure 6 , Figure 8 and Fig. 9A composite plate printing and coating device, wherein the vacuum mechanism 2 further comprises a cover plate 202 arranged in the machine body 1, the cover plate 202 and the vacuum chamber 201 are adapted to each other, a vacuum cylinder 203 is arranged in the machine body 1, a piston 204 is slidably arranged in the vacuum cylinder 203, a hose 205 is fixedly passed through the vacuum cylinder 203 and the cover plate 202, a hose 206 is fixedly passed through the bottom of the vacuum chamber 201 and the vacuum cylinder 203, a Y-shaped tube 207 is arranged on the vacuum cylinder 203, a one-way valve 208 is arranged in the hose 1 205 and the hose 2 206, a one-way valve 209 is arranged in the Y-shaped tube 207, when the cover plate 202 rotates and fits the vacuum chamber 201, the vacuum chamber 201 and the cover plate 202 cooperate to form a closed space, and the vacuum chamber 201 and the cover plate 202 are movable. When the plug 204 slides up and down along the inside of the vacuum cylinder 203, the one-way valve 1 208 and the one-way valve 2 209 cooperate to make the cover plate 202 and the bottom of the vacuum chamber 201 in a state of exhaustion. When the back plate of the mobile phone is placed on the U-shaped block 401, the air in the vacuum chamber 201 is extracted until it is in a vacuum state. The back plate of the mobile phone in the vacuum chamber 201 is plated through the body 1. When the cover plate 202 is rotated and unfolded, the bottom of the vacuum chamber 201 and the connection between the cover plate 202 and the hose 1 205 and the hose 2 206 are exhausted. The outside air enters from the hose 1 205 and the hose 2 206 to realize air cooling of the vacuum chamber 201 and the cover plate 202, and pre-cool the mobile phone back plate and the processing equipment before processing.

[0055] Further, the driving assembly 210 includes a motor 2101 disposed in the machine body 1, a connecting rod 2102 is disposed at the output end of the motor 2101, a strip ring 2103 is slidably disposed in the machine body 1, a push column 2104 is rotatably disposed on the connecting rod 2102, the push column 2104 is slidably disposed on the strip ring 2103, a sliding column 2105 is disposed in the air pump 203, one end of the sliding column 2105 is disposed on the piston 204, and the other end of the sliding column 2105 is disposed on the piston 204. On the strip ring 2103, the driving assembly 210 is used to drive the piston 204 to slide back and forth in the air pump 203. When the output end of the motor 2101 rotates, the connecting rod 2102 and the push column 2104 rotate synchronously, and the push column 2104 squeezes the strip ring 2103, so that the strip ring 2103 slides back and forth in a straight line along the inside of the body 1. At the same time, the sliding column 2105 slides synchronously with the strip ring 2103, thereby causing the piston 204 to slide back and forth along the air pump 203.

[0056] Further, the sealing assembly 211 includes a round table 2111 threadedly connected to the piston 204, a turntable 2112 is rotatably provided at the bottom of the vacuum cylinder 203, a push column 2104 is slidably provided on the turntable 2112, one end of the sliding column 2105 is provided on the round table 2111, and the other end of the sliding column 2105 is rotatably provided on the strip ring 2103, a driving disk 2113 is provided on the outer side of the sliding column 2105, a guide block 2114 is provided in the vacuum cylinder 203, and the piston 204 is slidably provided on the guide block 2114, and the sealing assembly 211 is used to adjust the distance between the piston 204 and the inner wall of the vacuum cylinder 203 The driving disk 2113 is slidably arranged on the outside of the sliding column 2105. When the driving disk 2113 is rotated, the driving disk 2113 drives the sliding column 2105 to rotate synchronously, and the sliding column 2105 drives the round table 2111 to rotate synchronously. The piston 204 is limited by the guide block 2114, so that the piston 204 cannot rotate, and then the round table 2111 is displaced along the thread direction of the piston 204. The bottom of the round table 2111 squeezes the piston 204, so that the piston 204 expands outward, so that the piston 204 is tightly attached to the vacuum cylinder 203, so that the distance between the piston 204 and the inner wall of the vacuum cylinder 203 is adjusted. Fig. 9 As shown, it is prevented that the piston 204 is used for a long time, resulting in a gap between the piston 204 and the inner wall of the vacuum cylinder 203, thereby resulting in a poor vacuuming effect, thereby improving the service life of the product;

[0057] Through the vacuum mechanism 2, when the cover plate 202 is rotated and unfolded, the processing equipment of the mobile phone back plate is pre-cooled before processing. When the cover plate 202 is rotated to fit the vacuum chamber 201, the vacuum chamber 201 is evacuated, so that the mobile phone back plate is in a vacuum environment during the coating process. The distance between the piston 204 and the inner wall of the vacuum cylinder 203 is adjusted through the sealing component 211 to prevent the piston 204 from being worn out due to long-term use, resulting in poor vacuum effect.

[0058] Example 2 further optimizes the composite plate printing and coating device provided in Example 1. Specifically, Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, the cleaning mechanism 3 also includes activated carbon 303 arranged in the hollow seat 301, and the Y-shaped tube 207 is fixedly penetrated on the hollow seat 301. Since the mobile phone back plate will generate harmful gas during the electroplating process, the harmful gas generated by the vacuum chamber 201 is discharged into the hollow seat 301 through the exhaust mechanism, and the harmful gas is filtered by the activated carbon 303 in the hollow seat 301, and finally the purified gas is discharged from the inclined tube 302, thereby reducing environmental pollution. At the same time, when the cover plate 202 is unfolded, since the output end of the inclined tube 302 is directly facing the bottom of the vacuum chamber 201, impurities will be generated in the vacuum chamber 201 after the mobile phone back plate is electroplated. When the inclined tube 302 discharges the purified gas, the impurities in the vacuum chamber 201 are blown out by the purified gas, thereby achieving cleaning of the vacuum chamber 201;

[0059] Furthermore, the fixing assembly 304 includes a transmission block 3041 slidably disposed on the body 1, a positioning shaft 3042 is disposed on the transmission block 3041, the cover plate 202 is rotatably disposed on the positioning shaft 3042, the fixing assembly 304 is used to fix the back plate of the mobile phone, the transmission block 3041 is linearly slidably disposed on the body 1, when the cover plate 202 rotates and the U-shaped block 401 squeezes the back plate of the mobile phone, the back plate of the mobile phone is fixed, and the displacement of the back plate of the mobile phone is prevented during the electroplating process;

[0060] Furthermore, a protrusion 305 is provided at the bottom of the cover plate 202, and the protrusion 305 is slidably provided on the vacuum chamber 201. By sliding the protrusion 305 in the vacuum chamber 201, the back plates of mobile phones of different sizes can be squeezed and fixed. When fixing a thicker back plate of a mobile phone, the protrusion 305 moves upward along the vacuum chamber 201, and the purified air is discharged on the surface of the cover plate 202 through the cleaning mechanism 3, so that the cover plate 202 and the protrusion 305 are always in a state of squeezing and fixing the back plate of the mobile phone. At this time, the cleaning mechanism 3 provides a downward pressure for the closed cover plate 202.

[0061] Furthermore, the positioning assembly 402 includes a rotating shaft 4021 rotatably arranged on the body 1, the U-shaped block 401 is arranged on the rotating shaft 4021, a worm gear 4022 is arranged on the rotating shaft 4021, a worm 4023 is rotatably arranged in the vacuum cylinder 203, the worm gear 4022 and the worm gear 4023 are adapted to each other, and the positioning assembly 402 is used to drive the mobile phone back plate to rotate and discharge, because the worm gear 4022 cannot drive the worm gear 4023 to rotate, when the mobile phone back plate is placed on the U-shaped block 401 and the cover plate 202 squeezes it at the same time, so that the U-shaped block 401 and the cover plate 202 are always In a parallel state, when the worm 4023 rotates, the worm 4023 drives the worm wheel 4022 to rotate, and the worm wheel 4022 drives the rotating shaft 4021 to rotate synchronously, and the U-shaped block 401 on the rotating shaft 4021 rotates synchronously. Through the rotation of the U-shaped block 401, the electroplated mobile phone back panel is ejected. At this time, the protrusion 305 on the cover plate 202 first moves upward. When the protrusion 305 is separated from the cooperation with the vacuum chamber 201, the cover plate 202 and the U-shaped block 401 rotate and unfold synchronously, so that the mobile phone back panel is discharged, which is convenient for the staff to take out the electroplated mobile phone back panel;

[0062] Furthermore, a rubber ring 403 is provided at the connection between the cover plate 202 and the positioning shaft 3042. When the cover plate 202 and the U-shaped block 401 rotate and unfold synchronously, the cover plate 202 that is rotated and unfolded is fixed by the rubber ring 403 to prevent the cover plate 202 from rotating and closing due to its own gravity. In this way, when the back plate of the mobile phone is placed on the U-shaped block 401, the cover plate 202 will not affect the feeding operation of the staff;

[0063] Furthermore, a wedge block 1 404 is provided at the end of the worm 4023, and a wedge block 2 405 is provided at the end of the round table 2111. The wedge block 1 404 and the wedge block 2 405 are adapted to each other. By rotating the driving disk 2113, the driving disk 2113 drives the sliding column 2105, the rotating disk 2112 and the round table 2111 to rotate synchronously. The round table 2111 moves and rotates along the thread in the piston 204, so that the wedge block 2 405 on the round table 2111 cooperates with the wedge block 1 404 on the worm 4023, so that the worm 4023 rotates, and then the U-shaped block 401 rotates to discharge the material;

[0064] When the cover plate 202 rotates and expands, the cleaning mechanism 3 is used to clean the impurities generated after the electroplating process of the vacuum chamber 201. When the cover plate 202 rotates and closes, the cleaning mechanism 3 applies pressure to the cover plate 202, so that the cover plate 202 and the U-shaped block 401 fix the back panel of the mobile phone. When the driving disk 2113 is rotated in the forward direction, the distance between the piston 204 and the vacuum cylinder 203 is adjusted by the table 2111. When the driving disk 2113 is rotated in the reverse direction, the wedge block 404 on the worm 4023 is driven to rotate by the wedge block 2 405 on the table 2111, so that the U-shaped block 401 is rotated and expanded, thereby realizing the discharge of the back panel of the mobile phone.

[0065] The use process of the composite plate printing coating device provided by the present invention is as follows:

[0066] When in use, place the back plate of the mobile phone on the U-shaped block 401, rotate and close the cover plate 202, so that the vacuum chamber 201 forms a closed space. Because the worm wheel 4022 cannot drive the worm 4023 to rotate, the U-shaped block 401 and the cover plate 202 are in a parallel state, start the motor 2101, and the motor 2101 drives the connecting rod 2102 and the push column 2104 to rotate synchronously. The push column 2104 squeezes the strip ring 2103, so that the strip ring 2103 slides back and forth in a straight line along the inside of the body 1, and the sliding column 2105 slides synchronously with the strip ring 2103, thereby causing the piston 204 to slide back and forth along the vacuum cylinder 203, and the one-way valve 208 and the one-way valve 204 are connected. 09, so that the hose 1 205 and the hose 2 206 are always in the state of exhausting, and the Y-shaped tube 207 is in the state of exhausting. When the cover plate 202 is rotated and unfolded, the bottom of the vacuum chamber 201 and the connection between the cover plate 202 and the hose 1 205 and the hose 2 206 are exhausted, and the outside air enters from the hose 1 205 and the hose 2 206 to realize the air cooling of the vacuum chamber 201 and the cover plate 202. Before the processing of the mobile phone back plate, the processing equipment is pre-cooled. When the cover plate 202 is rotated and closed, the vacuum chamber 201 is in the state of evacuating. Because the mobile phone back plate will produce harmful gases during the electroplating process, the harmful gases produced by the vacuum chamber 201 are discharged into the The activated carbon 303 in the hollow seat 301 filters the harmful gas, and finally the purified gas is discharged from the inclined tube 302, thereby reducing environmental pollution. At the same time, when the cover plate 202 is unfolded, because the output end of the inclined tube 302 is facing the bottom of the vacuum chamber 201, impurities will be generated in the vacuum chamber 201 after the back plate of the mobile phone is electroplated. When the inclined tube 302 discharges the purified gas, the impurities in the vacuum chamber 201 are blown out by the purified gas, thereby achieving the cleaning of the vacuum chamber 201. When the cover plate 202 is rotated and closed, the raised portion 305 on the cover plate 202 slides in the vacuum chamber 201, and then cooperates with the gas discharged from the inclined tube 302 to apply pressure to the cover plate 202. By applying pressure, the back plates of mobile phones of different sizes can be squeezed and fixed, so that the protrusion 305 is always in a state of squeezing and fixing the back plates of the mobile phones. When the driving disk 2113 is rotated forward, the driving disk 2113 drives the sliding column 2105 to rotate synchronously, and the sliding column 2105 drives the round table 2111 to rotate synchronously. The piston 204 is limited by the guide block 2114, so that the piston 204 cannot rotate, so that the round table 2111 is displaced along the thread direction of the piston 204, and the bottom of the round table 2111 squeezes the piston 204, and the piston 204 expands outward, and the piston 204 is tightly attached to the vacuum cylinder 203, so that the distance between the piston 204 and the inner wall of the vacuum cylinder 203 can be adjusted. Fig. 9As shown, to prevent the piston 204 from being used for a long time, which may cause a gap between the piston 204 and the inner wall of the vacuum cylinder 203 and thus result in a poor vacuuming effect, the driving disk 2113 is rotated in the opposite direction, and the driving disk 2113 drives the sliding column 2105, the turntable 2112 and the round table 2111 to rotate synchronously, and the round table 2111 is displaced and rotated along the thread in the piston 204, so that the wedge block 2 405 on the round table 2111 cooperates with the wedge block 1 404 on the worm 4023, so that the worm 4023 rotates, and then the U-shaped block 401 rotates to drive the electroplated mobile phone back panel to be discharged.
