Description
Technical Field
[0001] The present application relates to the field of mobile phone processing auxiliary technology, and in particular to an automatic film coating machine for mobile phone shells. Background Art
[0002] With the rapid development of the smartphone market, curved screen phones have gradually become mainstream. The design of the curved screen not only provides a better visual experience and a higher screen-to-body ratio, but also brings a smoother feel. However, the production process of the curved screen is complicated and has extremely high requirements for materials and processes. Especially in the film application process, due to the change in the curvature of the curved screen, the traditional flat film application method can no longer meet the needs. Manual film application is not only inefficient, but also prone to quality problems such as bubbles and dust, which seriously affects the user experience.
[0003] Although there are some semi-automatic or fully automatic film-laminating equipment on the market, most of these equipment can only process flat screens and are not ideal for curved screens. In addition, these equipment require manual intervention during operation, which increases production costs and time costs. Therefore, it is particularly important to develop a device that can automatically, efficiently and accurately complete the film coating of mobile phone shells.
[0004] In existing technologies, the process of coating the phone case usually includes the following steps: first, the staff needs to manually clean the phone screen to ensure that there is no dust and stains; then, the protective film is placed on the screen and flattened by hand or tools to remove air bubbles; finally, the excess film material is trimmed with a knife or other tools. This process is not only time-consuming, but also easily affected by human factors, resulting in unstable film quality.
[0005] In view of the above-mentioned related technologies, a solution is now proposed. Summary of the invention
[0006] The purpose of this application is to provide an automatic film coating machine for mobile phone shells to solve the technical problems in the prior art of being unable to accurately apply films, lacking curved screen adaptation, and having low production efficiency and product quality.
[0007] The present application provides an automatic film coating machine for mobile phone shells, which adopts the following technical solutions: A mobile phone shell automatic film wrapping machine comprises a workbench, an electrical box is arranged on one side of the outer wall of the workbench, a conveying mechanism is arranged above the electrical box, a spacing and dividing mechanism is arranged on one side of the conveying mechanism, a cleaning mechanism is arranged on one side of the spacing and dividing mechanism, a support frame is arranged on one side of the cleaning mechanism, a No. 1 screw is arranged at the center of the outer wall of the support frame, a displacement platform is arranged on the outer wall of the No. 1 screw, a No. 1 servo motor is arranged on the top of the displacement platform, a transmission belt is arranged on one side of the No. 1 servo motor, a feeding roller is arranged on one side of the transmission belt, two groups of feeding rollers are arranged, and the two groups of feeding rollers are evenly arranged along the vertical direction of the support frame, a negative pressure bin is arranged below the feeding roller, an exhaust pipe is arranged on one side of the negative pressure bin, and a negative pressure fan is arranged on one side of the exhaust pipe.
[0008] By adopting the above technical solution, the workbench is placed in a suitable position according to the actual site conditions, and it is ensured to be horizontal and stable; at the same time, all supporting parts are checked to be complete and intact, the electrical box is fixed at an appropriate height on the side of the workbench, and the power cable and other related lines are correctly connected according to the instructions. The conveyor belt and its supporting structure are installed in sequence according to the instructions of the drawings, and the tension is adjusted to the appropriate state to ensure smooth operation. Then, the spacing material distribution device and the cleaning module are assembled in the designated area, and attention is paid to maintaining a reasonable spacing between the components for subsequent debugging and use. Then, the overall frame structure including the No. 1 screw rod is constructed to ensure that its verticality is good and firm and reliable. The last step is to correctly install the No. 1 servo motor, the transmission belt and the two sets of feeding rollers in place, and achieve the best matching performance through precise adjustment. By setting up components such as the electrical box, the transmission mechanism, the spacing material distribution mechanism and the cleaning mechanism, the entire production process is highly automated, which greatly improves the production efficiency and product quality consistency. Secondly, the use of negative pressure adsorption to fix the mobile phone case to be processed can not only ensure that each component remains in a stable position during the processing process, but also effectively avoid damage or deformation caused by external forces. In addition, the No. 1 servo motor drives the transmission belt to drive the feed roller to rotate, and the displacement stage moves under precise control, so that the film material can fit evenly and tightly on the surface of the mobile phone case, thus achieving the ideal protection effect. Finally, the entire system is compact and reasonable in design, occupies a small area, and is easy to operate and maintain.
[0009] Preferably, universal wheels are provided at the four corners of the bottom of the workbench, a supporting foot is provided on one side of the universal wheel, an adjusting screw is provided above the supporting foot, the supporting foot is connected to the workbench through the adjusting screw, and the supporting foot can be translated up and down along the vertical direction of the adjusting screw by rotating the adjusting screw.
[0010] By adopting the above solution, by setting universal wheels at the four corners of the bottom of the workbench, the entire equipment can be easily moved to any desired position, greatly improving the flexibility and convenience of the production line layout. At the same time, each universal wheel is equipped with a support foot and an adjustment screw above it. This design not only increases the stability of the equipment, but also allows users to adjust the height of the workbench according to the actual working environment, thereby ensuring that the equipment is always in the best working condition. In addition, the support foot can achieve the function of up and down translation by rotating the adjustment screw, making the operation easier and faster, and the height adjustment can be completed without additional tools, further improving the user experience.
[0011] Preferably, the conveying mechanism comprises a fixed plate, a conveying wheel and a rubber belt, the conveying wheels are arranged on both sides of the fixed plate, and the rubber belt is arranged on the outer wall of the conveying wheel.
[0012] By adopting the above scheme, the design of the conveying mechanism as one of the core components of the equipment directly affects the operating efficiency and stability of the entire system. By adopting an efficient transmission system consisting of a fixed plate, a conveying wheel and a rubber belt, it can not only ensure that the product to be processed is smoothly and accurately sent to the next station, but also effectively reduce the wear caused by friction and extend the service life. In addition, this structure is compact and reasonable, easy to maintain and replace, and greatly reduces the operating costs of the enterprise. At the same time, due to the use of high-quality rubber materials to make the conveyor belt, the surface is softer and more elastic, which can well adapt to mobile phone cases of various shapes and sizes, avoid scratching or damage to the appearance of the product, and avoid the static electricity in the process from being transferred to the conveying mechanism to affect the long-term use of the device.
[0013] Preferably, the interval material distribution mechanism includes a dividing wheel, a No. 1 rotating shaft, a ratchet, a clamping arm, a protruding block, a No. 2 rotating shaft, a turntable and a spring, a dividing wheel is arranged on one side of the conveying mechanism, a No. 1 rotating shaft is arranged at the inner center of the dividing wheel, a ratchet is arranged on the top of the No. 1 rotating shaft, a clamping arm is arranged on one side of the ratchet wheel, a protruding block is arranged on one side of the outer wall of the clamping arm, a No. 2 rotating shaft is arranged on one side of the protruding block, a turntable is arranged on one side of the No. 2 rotating shaft, a hard edge is arranged on the outer wall of the turntable, and a spring is arranged on one side of the turntable. The dividing wheel and the ratchet are driven to rotate by the No. 1 rotating shaft, one side of the clamp arm is connected to the turntable through the spring, and one end of the clamp arm is combined with the concave hole of the ratchet to stop the dividing wheel from rotating. The rotation of the turntable drives the hard edge to contact the protruding block, so that the clamp arm rotates horizontally through the No. 2 rotating shaft, thereby separating the clamp arm from the ratchet, and returning the clamp arm to its original position through the spring. When the concave hole of the ratchet rotates to the position of the clamp arm, the ratchet and the clamp arm are moved.
[0014] By adopting the above scheme, a separation wheel is cleverly arranged on one side of the transmission mechanism, and a No. 1 rotating shaft is precisely arranged at the inner center of the separation wheel. The top of the No. 1 rotating shaft is further equipped with a ratchet wheel. This design enables the entire mechanism to achieve rotation through the drive of the No. 1 rotating shaft. A clamping arm is arranged on one side of the ratchet wheel, and a protruding block is arranged on one side of the outer wall of the clamping arm. Such a multi-level structural design ensures the stability and reliability of the mechanism during operation. A No. 2 rotating shaft is also carefully arranged on one side of the protruding block, and one side of the No. 2 rotating shaft is connected to the turntable. A hard edge is specially arranged on the outer wall of the turntable. This detailed design enables the turntable to have effective contact with the protruding block when rotating, thereby pushing the clamping arm to rotate horizontally through the No. 2 rotating shaft. At the same time, in order to ensure that the clamping arm can quickly return to its position after completing the rotation, a spring is also installed on one side of the turntable. When the separation wheel and the ratchet wheel rotate through the drive of the No. 1 rotating shaft, one side of the clamping arm will be connected to the turntable through the spring. This connection method not only ensures the stability of the clamp arm during rotation, but also enables one end of the clamp arm to be combined with the concave hole of the ratchet, thereby effectively preventing the rotation of the separation wheel. When the turntable rotates and drives the hard edge to contact the raised block, the clamp arm will rotate horizontally through the second shaft to separate from the ratchet. At this time, the role of the spring is particularly important. It can ensure that the clamp arm quickly returns to its position after completing the rotation and prepare for the next operation. In summary, the application of this interval material distribution mechanism in the automatic film coating machine for mobile phone shells not only improves production efficiency and reduces labor intensity, but also ensures the stability and accuracy of the processing process. Its unique design and fine manufacturing process fully demonstrate the charm and advantages of modern mechanical design.
[0015] Preferably, the cleaning mechanism includes a second screw, a lifting workbench, a cleaning roller and a sticky roller, a lifting workbench is provided on one side of the outer wall of the second screw, a cleaning roller is provided at the bottom center of the lifting workbench, and sticky rollers are provided on both sides of the cleaning roller.
[0016] By adopting the above scheme, a lifting workbench is cleverly set on one side of the outer wall of the second screw rod, so that the height of the entire mechanism can be adjusted according to actual needs, so as to adapt to mobile phone shells of different sizes and shapes. The cleaning roller is precisely arranged at the bottom center of the lifting workbench. This design enables the cleaning roller to directly act on the surface of the mobile phone shell to achieve efficient cleaning. In order to further improve the cleaning effect, sticky rollers are set on both sides of the cleaning roller. The function of the sticky roller is to remove tiny impurities and residues on the surface of the mobile phone shell through adhesion during the cleaning process, ensuring that the surface of the shell is clean and flawless after cleaning. This double-roller design not only improves the cleaning effect, but also extends the service life of the cleaning roller. In addition, the design of the lifting workbench also fully considers the convenience and safety of operation. Through simple operation, the height of the lifting workbench can be easily adjusted to adapt to different working environments and needs. At the same time, the structure of the lifting workbench is stable and reliable, and can withstand a certain weight and use pressure, ensuring the stable operation of the entire mechanism. In summary, the application of the cleaning mechanism in the automatic film coating machine for mobile phone shells not only improves production efficiency and reduces labor intensity, but also ensures the stability and accuracy of the processing process.
[0017] Preferably, the negative pressure bin comprises a bin body shell, a soft layer, a scraper bracket, a slide rail and a scraper, a soft layer is provided at the bottom of the bin body shell, a scraper bracket is provided at the inner center of the bin body shell, slide rails are provided on both sides of the scraper bracket, a scraper is provided on one side of the slide rail, the bottom of the scraper is trapezoidal, and the bottom of the scraper is provided with ridges, the scrapers are provided in three groups, and each group of scrapers is evenly arranged along the horizontal direction of the slide rail.
[0018] By adopting the above scheme, a soft layer is cleverly arranged at the bottom of the warehouse shell. This design enables the entire negative pressure warehouse to better adapt to mobile phone shells of different shapes and sizes, while avoiding scratches or damage to the shell surface. At the inner center of the warehouse shell, a scraper bracket is precisely arranged to provide strong support for the stable operation of the scraper. In order to achieve smooth sliding and precise positioning of the scraper, slide rails are arranged on both sides of the scraper bracket. The design of the slide rail fully considers the friction and stability to ensure that the scraper can remain stable and not easily deviate from the track during the sliding process. On one side of the slide rail, a scraper is installed. These scrapers are key components for cleaning the surface of the mobile phone shell. The bottom of these scrapers is trapezoidal and is arranged There are convex ridges. This design enables the scraper to fit the surface of the mobile phone shell more closely during sliding, thereby more effectively removing impurities and residues on the surface. At the same time, the trapezoidal design also helps to reduce the contact area between the scraper and the shell, reduce friction, and increase service life. In addition, in order to further improve the cleaning efficiency and coverage area, the scrapers are set into three groups, and each group of scrapers is evenly arranged along the horizontal direction of the slide rail. Such a layout makes full use of the cleaning area in the entire negative pressure bin, ensuring comprehensive cleaning of the surface of the mobile phone shell. In summary, the application of the negative pressure bin in the automatic coating machine for mobile phone shells not only improves production efficiency and reduces labor intensity, but also ensures the stability and accuracy of the processing process.
[0019] Preferably, a control console is provided on one side of the conveying mechanism, through which the conveying mechanism is stopped 5 seconds after the turntable completes each rotation, and the conveying mechanism and the turntable are started simultaneously when the translation stage rises.
[0020] By adopting the above scheme, a control console is carefully arranged on one side of the conveying mechanism. This layout makes the operation more convenient and also facilitates monitoring of the entire processing process. Through the control console, the operator can easily control the parameters such as the start, stop and speed adjustment of the conveying mechanism, thereby realizing precise control of the processing process. The control console is programmed to automatically stop the operation of the conveying mechanism 5 seconds after each rotation of the turntable. This design takes into account the inertia that may be generated by the turntable during the rotation process and the preparation time for subsequent processing steps, ensures the synchronization between the conveying mechanism and the turntable, and avoids processing errors or collisions caused by speed differences. In addition, when the translation table rises, the control console can start the conveying mechanism and the turntable at the same time. This function makes the entire processing flow more coherent, reduces waiting time and unnecessary downtime. The rise of the translation table usually means the beginning of a new processing cycle. At this time, the synchronous start of the conveying mechanism and the turntable can ensure that the new mobile phone shell can enter the processing area in time, thereby improving the overall production efficiency. In summary, the application of the coordinated work of the conveying mechanism and the control console in the automatic film coating machine for mobile phone shells not only improves production efficiency and reduces labor intensity, but also ensures the stability and accuracy of the processing process.
[0021] Preferably, the displacement platform drives the negative pressure bin to move downward, so that the soft layer wraps around the mobile phone on the conveying mechanism below, and the negative pressure fan extracts the gas in the bin shell through the exhaust pipe. At the same time, the feeding roller aligns the material with the mobile phone by rotating, and the scraper moves horizontally along the material through the slide rail, and the material and the mobile phone are completely fitted together by the downward pressure of the convex ridge. After the fitting is completed, the negative pressure fan runs in the opposite direction to restore the pressure inside the bin shell, and the negative pressure bin moves upward through the displacement platform.
[0022] By adopting the above scheme, the precise control of the displacement table enables the negative pressure bin to move down to a suitable position, thereby ensuring that the soft layer can tightly wrap around the mobile phone on the conveying mechanism below. This wrapping method not only improves the processing quality, but also avoids scratches or damage to the mobile phone shell. At the same time, the negative pressure fan extracts the gas in the bin shell through the exhaust pipe to form a negative pressure environment. This operation helps to fix the position of the mobile phone shell to prevent it from moving or deforming during the processing. The feeding roller aligns the material with the mobile phone by rotating, ensuring the accuracy and fit of the subsequent scraper operation. The scraper moves horizontally along the material through the slide rail, and the material is completely fit with the mobile phone by pressing down the ridge. This fitting method not only improves the fitting accuracy, but also reduces the generation of bubbles and wrinkles, thereby improving the overall quality and aesthetics of the product. When the fitting is completed, the negative pressure fan runs in the reverse direction to restore the pressure inside the bin shell. This operation helps to easily remove the negative pressure bin from the mobile phone shell to prepare for the next processing cycle, and the upward movement of the displacement table further ensures the continuity and efficiency of the entire processing flow.
[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting up components such as electrical boxes, transmission mechanisms, interval material distribution mechanisms and cleaning mechanisms, the entire production process is highly automated. This automated design greatly improves production efficiency, reduces labor intensity, and ensures the stability and accuracy of the processing process; 2. Use negative pressure adsorption to fix the mobile phone case to be processed, ensuring that each component maintains a stable position during the processing process, effectively avoiding damage or deformation caused by external forces, and improving product quality consistency; 3. The No. 1 servo motor drives the transmission belt to drive the feed roller to rotate, and the displacement table moves under precise control, so that the film material can be evenly and tightly attached to the surface of the mobile phone case, achieving an ideal protection effect and improving the appearance quality and durability of the product; 4. By setting universal wheels at the four corners of the bottom of the workbench, the entire equipment can be easily moved to any required position, greatly improving the flexibility and convenience of the production line layout.

[0029] Specifically, an electrical box 2 is provided on one side of the outer wall of the workbench 1. The electrical box 2 is used to install and protect various electrical components, such as controllers, relays, etc., to ensure the normal operation of the equipment. A conveying mechanism 3 is provided above the electrical box 2, which is responsible for conveying the mobile phone shell to be processed from one end to the other end. The conveying mechanism 3 is usually driven by a belt or chain, and is driven by a motor to achieve smooth and efficient transmission. A spacing and material distribution mechanism 4 is provided on one side of the conveying mechanism 3. The function of this mechanism is to ensure that a certain distance is maintained between each mobile phone shell to prevent them from colliding with each other and causing damage. Next, a cleaning mechanism 5 is provided on one side of the spacing and material distribution mechanism 4. This part is specifically used to remove dust, oil and other impurities on the surface of the mobile phone shell to ensure the quality of subsequent processes. After cleaning, the mobile phone shell will be sent to the support frame 6. The support frame 6 is located at the center of the entire system. A No. 1 screw 7 is installed at the center of the outer wall of the support frame 6. This is a precision transmission element that can convert rotational motion into linear motion. A displacement platform 8 is installed on the No. 1 screw 7. When the screw rotates, the displacement platform 8 will move along the predetermined trajectory. A No. 1 servo motor 9 is installed on the top of the displacement platform 8. This is a high-performance motor with the characteristics of fast response speed and high control accuracy. Its rotation speed and direction can be accurately controlled through programming, which in turn affects the specific action of the displacement platform 8.

Install each component in place in sequence according to the instructions in the manual, paying special attention to check whether all screws are tightened to avoid looseness and potential safety hazards. Fix the four universal wheels 15 to the corresponding positions on the bottom of the workbench 1, then insert the support feet 16 into the reserved holes next to the universal wheels 15, and use the matching bolts for preliminary fixation. Finally, adjust the adjustment screw 17 on each support foot 16 until the entire workbench 1 is horizontal. After completing the above steps, conduct a comprehensive functional test, including but not limited to the mobility, stability, and whether the height adjustment mechanism is operating normally. It can be put into formal use only after confirmation. At the same time, the equipment can be fine-tuned according to actual production needs, such as adding anti-slip pads to enhance safety or adjusting the conveyor belt speed to match the processing requirements of products of different specifications.
[0032] Reference Figure 1 and Figure 6 The conveying mechanism 3 includes a fixed plate 301 , a conveying wheel 302 and a rubber belt 303 . Conveying wheels 302 are arranged on both sides of the fixed plate 301 , and a rubber belt 303 is arranged on the outer wall of the conveying wheel 302 .
[0033] Specifically, the pre-prepared fixing plate 301 is correctly installed in the corresponding hole position of the workbench 1 according to the instructions on the drawing, and reinforced with bolts, paying attention to keeping it in a horizontal state to ensure that the subsequent components can be assembled smoothly, and the conveying wheels 302 on the left and right sides are fixed by bolts at both ends of the fixing plate 301, and it is confirmed that each conveying wheel 302 can rotate freely without hindrance. According to actual needs, the spacing between the conveying wheels 302 is adjusted to meet the requirements of the production line layout, and then a rubber belt 303 of appropriate length and width is selected, and it is carefully wrapped around the two conveying wheels 302 from one end, and gradually tightened until the appropriate tension is reached, but do not over-stretch it to avoid breakage. After completing the above steps, a comprehensive functional test is carried out, including but not limited to starting the motor to observe whether the rubber belt 303 runs smoothly, checking whether there is abnormal noise, etc., and it can be put into formal use only after confirmation.
[0034] Reference Figure 1 and Figure 2The interval material distribution mechanism 4 includes a separation wheel 401, a No. 1 rotating shaft 402, a ratchet 403, a clamping arm 404, a protruding block 405, a No. 2 rotating shaft 406, a turntable 407 and a spring 408. A separation wheel 401 is arranged on one side of the conveying mechanism 3, a No. 1 rotating shaft 402 is arranged at the inner center of the separation wheel 401, a ratchet 403 is arranged on the top of the No. 1 rotating shaft 402, a clamping arm 404 is arranged on one side of the ratchet 403, a protruding block 405 is arranged on one side of the outer wall of the clamping arm 404, a No. 2 rotating shaft 406 is arranged on one side of the protruding block 405, a No. 2 rotating shaft 406 is arranged on one side of the turntable 407, and a hard edge 15 is arranged on the outer wall of the turntable A spring 408 is provided on one side of 407, and the dividing wheel 401 and the ratchet 403 are rotated by being driven by the No. 1 rotating shaft 402. One side of the clamping arm 404 is connected to the turntable 407 through the spring 408, and one end of the clamping arm 404 is combined with the concave hole of the ratchet 403 to stop the dividing wheel 401 from rotating. The rotation of the turntable 407 drives the hard edge 15 to contact the protruding block 405, so that the clamping arm 404 rotates horizontally through the No. 2 rotating shaft 406, thereby separating the clamping arm 404 from the ratchet 403, and the clamping arm 404 is returned to its position by the spring 408. When the concave hole of the ratchet 403 rotates to the position of the clamping arm 404, the ratchet 403 and the clamping arm 404 are moved.
[0035] Specifically, a separation wheel 401 is provided on one side of the transmission mechanism 3, which is one of the core components of the entire interval material distribution mechanism 4. A No. 1 rotating shaft 402 is provided at the inner center of the separation wheel 401. The No. 1 rotating shaft 402 is fixed to the separation wheel 401 by a bearing or by directly interfering with the separation wheel 401 to ensure that it can rotate smoothly and transmit power. A ratchet 403 is provided on the top of the No. 1 rotating shaft 402. The ratchet 403 and the No. 1 rotating shaft 402 are also fixed in a tight fitting manner, such as a key connection or a threaded connection, to ensure that the two rotate synchronously. The design of the ratchet 403 enables it to interact with the clamping arm 404 during rotation, thereby realizing the material distribution function. A protrusion 405 is provided on one side of the clamping arm 404. The protrusion 405 is fixed to the clamping arm 404 by welding, bolt connection or other means, as a component in contact with the hard edge 15 on the turntable 407. This design enables the hard edge 15 to push the turntable 407 when the turntable 407 rotates. The movable protrusion block 405 drives the clamping arm 404 to rotate in the horizontal direction. The second rotating shaft 406 is arranged on the other side of the clamping arm 404, which is used to support the clamping arm 404 and enable it to rotate around the axis. The second rotating shaft 406 and the clamping arm 404 are also fixed in a close-fitting manner, such as a bearing connection or an interference fit, to ensure that the rotation of the clamping arm 404 is smooth and stable. The turntable 407 serves as the driving part of the entire interval distribution mechanism 4, and a hard edge 15 is arranged on its outer wall. The turntable 407 is driven to rotate by a motor or other power source, thereby driving the hard edge 15 to contact the protrusion block 405. This design enables the rotation of the turntable 407 to be directly converted into the horizontal rotation movement of the clamping arm 404. The spring 408 is arranged between the clamping arm 404 and the turntable 407 to provide a reset force. When the clamping arm 404 rotates due to the push of the hard edge 15, the spring 408 can quickly pull it back to its original position to ensure the smooth progress of the next distribution operation.
[0036] Reference Figure 1 and Figure 3 The cleaning mechanism 5 includes a second screw 501, a lifting workbench 502, a cleaning roller 503 and a sticking roller 504. The lifting workbench 502 is arranged on one side of the outer wall of the second screw 501, the cleaning roller 503 is arranged at the bottom center of the lifting workbench 502, and the sticking rollers 504 are arranged on both sides of the cleaning roller 503.
[0037] Specifically, the second screw rod 501 is the driving part of the entire cleaning mechanism 5, and a lifting platform 502 is arranged on one side of its outer wall. The lifting platform 502 is fixed to the second screw rod 501 by a nut or a threaded connection, so that the lifting platform 502 can move up and down along the length direction of the second screw rod 501. This design is not only convenient for adjusting the distance between the cleaning roller 503 and the mobile phone shell, but also can adapt to mobile phone shells of different thicknesses. A cleaning roller 503 is arranged at the bottom center of the lifting platform 502, which is one of the core components of the cleaning mechanism 5. The cleaning roller 503 is fixed thereon by a bearing or by directly interfering with the lifting platform 502, ensuring that the cleaning roller 503 It can rotate smoothly and perform cleaning operations. The surface of the cleaning roller 503 is usually covered with soft cleaning materials, such as flannel or sponge, to provide a gentle and effective cleaning effect. Sticky rollers 504 are arranged on both sides of the cleaning roller 503, which is another important component of the cleaning mechanism 5. The sticky rollers 504 are fixed to the lifting workbench 502 through a bracket or directly, and their positions correspond to the cleaning rollers 503. The surface of the sticky rollers 504 is covered with a material with strong stickiness, such as silica gel or a special adhesive, which is used to adhere to and remove tiny particles and impurities on the surface of the mobile phone shell. When the mobile phone shell passes through the cleaning rollers 503, the sticky rollers 504 can fit tightly to the surface of the mobile phone shell to ensure the effective removal of impurities.
[0038] Reference Figure 1 , Figure 4 and Figure 5 The negative pressure bin 12 includes a bin shell 1201, a soft layer 1202, a scraper bracket 1203, a slide rail 1204 and a scraper 1205. The soft layer 1202 is arranged at the bottom of the bin shell 1201, and the scraper bracket 1203 is arranged at the inner center of the bin shell 1201. Slide rails 1204 are arranged on both sides of the scraper bracket 1203. A scraper 1205 is arranged on one side of the slide rail 1204. The bottom of the scraper 1205 is trapezoidal, and a ridge 12051 is arranged at the bottom of the scraper 1205. There are three groups of scrapers 1205, and each group of scrapers 1205 is evenly arranged along the horizontal direction of the slide rail 1204.
[0039] Specifically, the silo shell 1201 serves as the frame structure of the entire negative pressure silo 12, and a soft layer 1202 is arranged at its bottom. The soft layer 1202 is made of a soft and elastic material, such as silicone or rubber, and is fixed to the bottom of the silo shell 1201 by bonding or inlaying. This design can provide a buffering effect and ensure the sealing of the silo shell 1201 when the negative pressure fan 14 is exhausting air. A scraper bracket 1203 is arranged at the inner center of the silo shell 1201, and the scraper bracket 1203 is fixed to the silo shell 1201 by bolt connection or welding to ensure its stability and durability. The design of the scraper bracket 1203 enables it to firmly support the scraper 1205 and enable it to move smoothly along the slide rail 1204. Slide rails 1204 are arranged on both sides of the scraper bracket 1203, and the slide rails 1204 are connected to the scraper bracket by screw connection or welding. 1203 are fixed together, and the design of the slide rail 1204 enables the scraper 1205 to slide smoothly thereon, thereby achieving uniform pressure on the surface of the mobile phone shell. A scraper 1205 is arranged on one side of the slide rail 1204, and the scraper 1205 is connected to the slide rail 1204 through a mounting seat or a clamping device. The bottom of the scraper 1205 is trapezoidal, which helps to better adapt to the curved surface of the mobile phone shell and ensure that uniform pressure is applied during the coating process. The bottom of the scraper 1205 is also provided with a ridge 12051, which increases the friction between the scraper 1205 and the surface of the mobile phone shell, thereby improving the quality and stability of the coating. The scraper 1205 is provided with three groups, and each group of scrapers 1205 is evenly arranged along the horizontal direction of the slide rail 1204. This layout ensures that the surface of the mobile phone shell can be subjected to uniform pressure during the entire coating process, thereby improving the accuracy and consistency of the coating.
[0040] Reference Figure 1 and Figure 2 A control console 18 is provided on one side of the conveying mechanism 3, and the conveying mechanism 3 is stopped 5 seconds after each rotation of the turntable 407 is completed through the control console 18, and the conveying mechanism 3 and the turntable 407 are started simultaneously when the translation stage 8 rises.
[0041] Specifically, the conveying mechanism 3 and the console 18 are highly integrated through an electrical control system. The console 18 serves as a central control unit with built-in programming logic, which is responsible for receiving and processing data from the device and issuing instructions to the conveying mechanism 3 and other related components according to a preset program. After the turntable 407 completes a rotation, the console 18 uses a built-in timer or clock module to accurately control the time delay of 5 seconds. This delay ensures that the turntable 407 has enough time to stabilize and avoid vibration or displacement caused by immediate stop, thereby providing a stable environment for the next operation. When the displacement table 8 starts to rise, the console 18 monitors this change through the sensor of the console 18, and then triggers the simultaneous start of the conveying mechanism 3 and the turntable 407. The brief pause after the turntable 407 rotates helps to reduce the error accumulation caused by dynamic adjustment and ensure the accuracy of the coating position each time. At the same time, the synchronous start mechanism ensures that the mobile phone shell enters the next process in the best condition, further improving the quality and consistency of the finished product.
[0042] Reference Figure 1 , Figure 4 and Figure 5 The displacement table 8 drives the negative pressure bin 12 to move downward, so that the soft layer 1202 wraps around the mobile phone on the conveying mechanism 3 below, and the negative pressure fan 14 extracts the gas in the bin shell 1201 through the exhaust pipe 13. At the same time, the feeding roller 11 rotates to align the material with the mobile phone, and the scraper 1205 moves horizontally along the material through the slide rail 1204. The material and the mobile phone are completely fitted together through the downward pressure of the ridge 12051. After the fitting is completed, the negative pressure fan 14 runs in the opposite direction to restore the pressure inside the bin shell 1201, and the negative pressure bin 12 moves upward through the displacement table 8.
[0043] Specifically, the displacement table 8 is driven by a high-precision servo motor and realizes precise movement in the vertical direction through a ball screw or belt drive. When receiving a control signal, the displacement table 8 drives the entire negative pressure bin 12 to move downward steadily to ensure that the soft layer 1202 can accurately contact the mobile phone shell on the conveying mechanism 3 below. The negative pressure fan 14 is connected to the bin shell 1201 through the exhaust pipe 13 to form a closed negative pressure environment. When the mobile phone shell needs to be wrapped, the negative pressure fan 14 is started to quickly extract the air in the bin body so that the soft layer 1202 is close to the mobile phone shell. After the wrapping is completed, the negative pressure fan 14 runs in the opposite direction and slowly injects air to restore the normal pressure in the bin shell 1201 to facilitate subsequent operations. The scraper 1205 is installed on the slide rail 1204. By applying a constant pressure to the mobile phone shell, when the material is initially in contact with the mobile phone shell, the scraper 1205 moves horizontally along the slide rail 1204, and uses the convex ridge 12051 to press the material down to ensure that it is completely in contact with the surface of the mobile phone shell without bubbles or wrinkles.
[0044] The implementation principle of the embodiment of the present application is as follows: first, the mobile phone to be coated is placed on the conveying mechanism 3 on the workbench 1, and the operation of the entire equipment is controlled by the electrical box 2. The conveying mechanism 3 conveys the mobile phone to the spacing material distribution mechanism 4, which realizes the precise control of the passing time of the mobile phone through the cooperation of the separation wheel 401 and the clamping arm 404. Then, the cleaning mechanism 5 cleans the surface of the mobile phone to ensure the coating quality. Then, the No. 1 screw 7 on the support frame 6 drives the displacement table 8 to move downward, so that the negative pressure bin 12 contacts the mobile phone, and the negative pressure fan 14 is turned on. The gas in the bin shell 1201 is extracted through the exhaust pipe 13 to form a negative pressure environment. At this time, the feeding roller 11 rotates to align the material with the mobile phone. The scraper 1205 moves horizontally along the material through the slide rail 1204, and uses the convex ridge 12051 to press down to make the material and the mobile phone fit completely. Finally, after the fitting is completed, the negative pressure fan 14 runs in the opposite direction to restore the pressure inside the bin shell 1201, and the negative pressure bin 12 moves up through the displacement table 8 to complete a coating process. The whole process has a high degree of automation, which improves production efficiency and product quality.
