Technical Field
[0001] This utility model relates to the field of mobile phone manufacturing equipment technology, and in particular to a mobile phone back cover coating device. Background Technology
[0002] With the rapid development of the smartphone industry, consumers are increasingly demanding higher standards for the appearance and texture of their phones. Surface treatment processes for phone back covers, especially coating processes, have become a key factor in enhancing product added value. Traditional phone back cover coating operations often rely on manual operation or simple automated equipment, which present the following main problems.
[0003] Existing automated coating equipment typically employs linear reciprocating or spray coating methods during coating operations. Linear reciprocating coating is difficult to perfectly conform to the curved surface or special shape of the phone back cover, easily leading to uneven coating or low efficiency. While spray coating is more adaptable, it suffers from low material utilization, difficulty in controlling environmental pollution, and difficulty in accurately controlling the consistency of coating thickness. This lack of a refined and efficient coating mechanism design makes it difficult to significantly improve coating efficiency and ensure the consistency of coating quality, thus limiting the capacity and yield of automated production lines.
[0004] Therefore, this utility model proposes a mobile phone back cover coating device to solve the shortcomings of the prior art in terms of coating efficiency and coating quality consistency. Utility Model Content
[0005] In view of the problems that the existing mobile phone back cover coating device has low coating efficiency and difficulty in ensuring the consistency of coating quality due to its structural design, this utility model aims to provide a mobile phone back cover coating device with an improved structure that can effectively solve the above problems.
[0006] This utility model provides a mobile phone back cover coating device, including: an outer box, a conveying platform, and a motor; and a coating mechanism.
[0007] The coating mechanism includes an eccentric shaft, a limiting shaft, a pull rod, a first rotating shaft, a second rotating shaft, a first lever, a clamping block, a second lever, and a coating plate.
[0008] Furthermore, the motor is fixedly connected to the top of the inner wall of the outer casing; the conveying platform is located inside the lower part of the outer casing; the eccentric shaft is rotatably connected to the output end of the motor; the limiting shaft is eccentrically located at the other end of the eccentric shaft; the pull rod is rotatably connected to the limiting shaft; both the first rotating shaft and the second rotating shaft are rotatably connected to the top of the inner wall of the outer casing; one end of the first lever is rotatably connected to the first rotating shaft, and the other end of the first lever is rotatably connected to the pull rod; the clamping block is fixedly connected to the other end of the first lever; one end of the second lever is rotatably connected to the second rotating shaft, and the other end is fixedly connected to the clamping block; the coating plate is fixedly connected to the bottom of the clamping block.
[0009] Preferably, the mobile phone back cover coating device further includes a protective mechanism, which is located at the middle of the conveying platform. The protective mechanism includes a fixed box and a cylinder. The fixed box is fixed to the bottom of the middle of the conveying platform, and the cylinder is vertically installed inside the fixed box.
[0010] Preferably, the above-mentioned protective mechanism further includes a baffle plate connected to the top of the piston rod of the cylinder. The cylinder drives the baffle plate to lift and lower through the extension and retraction of its piston rod, thereby physically blocking the back cover of the mobile phone on the conveying platform.
[0011] Preferably, the protective mechanism further includes a fixing plate that covers the top opening of the fixing box, and the piston rod of the cylinder passes upward through the fixing plate from inside the fixing box. The fixing plate provides an installation and guiding reference for the movement of the cylinder.
[0012] Preferably, a guide rod is also provided on the fixed plate. The guide rod is vertically fixed to both sides of the fixed plate. The guide rod is used to precisely guide the pushing path of the piston rod of the cylinder when it moves, so as to prevent deflection and ensure the stability of lifting.
[0013] Preferably, a stabilizing block is also fixed to the top of the baffle, which provides a structural foundation for the subsequent installation of the roller and increases the structural stability of the top of the baffle.
[0014] Preferably, a roller is rotatably connected between the stabilizing blocks, and the axis of the roller is set horizontally so that it can rotate freely between the stabilizing blocks to accommodate the passage of the phone back cover.
[0015] Preferably, the height of the roller is precisely designed so that when the baffle is pulled down to the retracted position by the cylinder, the roller is placed in the middle of the conveying platform, with its top surface flush with the surface of the conveying platform, so as to restore the smooth conveying of the mobile phone back cover.
[0016] This utility model has the following beneficial effects: 1. This utility model, by setting up a coating mechanism, uses a motor to drive an eccentric shaft, and through the linkage of a limit shaft, a pull rod, lever one, and lever two, enables the coating plate to perform stable swing coating under the drive of the clamping block. This solves the problems of low coating efficiency, poor coating uniformity, and low automation in the prior art for mobile phone back cover coating, and achieves the effects of automated and efficient coating, improved production efficiency, reduced labor costs, and guaranteed coating quality consistency.
[0017] 2. This utility model, by setting up a protective mechanism, uses a cylinder installed in a fixed box to receive signals to drive a baffle to rise and block the back cover of the mobile phone on the conveying platform. This solves the problem in the prior art that the back covers of the mobile phone are prone to pile-up, collision and damage when the workload of the conveying platform increases or the process is paused. When needed, it can effectively block and buffer the back cover of the mobile phone, avoid material collision and greatly reduce the damage rate of the back cover of the mobile phone.
[0018] 3. This utility model solves the problems of potential misalignment and instability of the protective baffle during lifting and lowering, as well as the impact on the smoothness of transmission when the baffle is retracted, by setting a guide rod on the fixed plate to guide the pushing path of the cylinder, and setting a stabilizing block and roller on the top of the baffle. This ensures stable lifting and lowering of the baffle, avoids misalignment, and allows the back cover of the mobile phone to pass smoothly without jamming when resuming transmission.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example: Please refer to Figures 1 to 4 This utility model provides a mobile phone back cover coating device, which aims to solve the technical problems existing in the prior art. Existing mobile phone back cover coating devices may have problems such as low automation and low coating efficiency. At the same time, during continuous transmission, there is a lack of effective buffering and protection mechanisms, which can easily cause the mobile phone back cover to collide and be damaged due to accumulation, affecting product yield and production stability.
[0023] like Figure 1 and Figure 2 As shown, a mobile phone back cover coating device includes an outer casing 1 and a conveying platform 5, which is located inside the lower part of the outer casing 1. The outer casing 1 serves as the mounting base and housing for the entire device, providing installation space and protection for the subsequent coating mechanism 2 and protective mechanism 3. The conveying platform 5 is used to transport the mobile phone back cover, allowing it to pass sequentially through the area of the protective mechanism 3 and the working area of the coating mechanism 2. Figure 1 As shown, motor 4 is fixedly connected to the top of the inner wall of outer box 1. Motor 4 serves as a power source to drive the coating mechanism 2. The device also includes coating mechanism 2 installed above conveying platform 5 and protective mechanism 3 installed in the middle of conveying platform 5. Coating mechanism 2 is used to apply coating to the back cover of mobile phone conveyed by conveying platform 5. Protective mechanism 3 is used to block and buffer subsequent back covers of mobile phone conveying platform 5 when coating operation is busy or when conveying is congested.
[0024] Please refer to Figure 3 The structure of coating mechanism 2 will be described in detail below: The coating mechanism 2 has a lever transmission assembly, which includes an eccentric shaft 201 rotatably connected to the output end of the motor 4; a limiting shaft 202 eccentrically positioned at the other end of the eccentric shaft 201; and a pull rod 203 rotatably connected to the limiting shaft 202. When the motor 4 drives the eccentric shaft 201 to rotate, the limiting shaft 202 drives the pull rod 203 to perform horizontal reciprocating motion. The coating mechanism 2 also has a first rotating shaft 204 and a second rotating shaft 206, both rotatably connected to the top of the inner wall of the outer casing 1. One end of a lever 205 is rotatably connected to the first rotating shaft 204. The other end is rotatably connected to the pull rod 203, so that it swings around the first rotating shaft 204 under the reciprocating motion of the pull rod 203; the clamping block 207 is fixedly connected to the other end of the first lever 205; one end of the second lever 209 is rotatably connected to the second rotating shaft 206, and the other end of the second lever 209 is fixedly connected to the clamping block 207. The second lever 209 is used to synchronously drive the clamping block 207 to swing when the first lever 205 swings; the coating plate 208 is fixedly connected to the bottom of the clamping block 207. The coating plate 208 swings and coats the back cover of the mobile phone with the swing of the clamping block 207, which improves the efficiency and consistency of coating.
[0025] In a preferred embodiment, the device also includes a protective mechanism 3, which is disposed at the middle of the conveying platform 5 and is used to block the back cover of the mobile phone when the conveying is congested. The protective mechanism 3 includes a fixed box 301 and a cylinder 302. The fixed box 301 is fixed to the bottom of the middle of the conveying platform 5 and is used to provide a mounting base for the cylinder 302. The cylinder 302 is vertically installed in the fixed box 301 and serves as an actuator to receive signals and generate upward or downward linear motion.
[0026] As another preferred embodiment, the protective mechanism 3 also includes a baffle 305, which is connected to the top of the piston rod of the cylinder 302. The cylinder 302 drives the baffle 305 to move up and down, so that it passes through the surface of the conveying platform 5 to block the subsequent mobile phone back cover on the conveying platform 5.
[0027] In another preferred embodiment, the protective mechanism 3 further includes a fixing plate 303, which covers the top of the fixing box 301. The piston rod of the cylinder 302 passes upward through the fixing plate 303. The fixing plate 303 is used to close the fixing box 301 and provides a through guide for the piston rod of the cylinder 302.
[0028] As another preferred embodiment, the protective mechanism 3 also includes a guide rod 304, which is vertically fixed to both sides of the fixed plate 303. The guide rod 304 is used to guide and limit the path of the cylinder 302 pushing the baffle 305 upward, so as to avoid the piston rod from being misaligned or deflected during the movement and to ensure the stability of lifting.
[0029] In another preferred embodiment, a stabilizing block 306 is fixed to the top of the baffle 305, and the stabilizing block 306 is used to support the roller 307.
[0030] In another preferred embodiment, a roller 307 is rotatably connected between the stabilizing blocks 306. The roller 307 has a cylindrical structure and is used to form a smooth transition with the surface of the conveying platform 5 when the baffle 305 retracts, so as to restore the conveying of the mobile phone back cover.
[0031] In another preferred embodiment, when the baffle 305 is pulled down by the cylinder 302, the roller 307 is placed at the middle of the conveying platform 5, so that its top surface is flush with or slightly lower than the conveying surface of the conveying platform 5, thereby allowing the back cover of the mobile phone to pass through smoothly and resume normal conveying and processing.
[0032] Working principle: When the back cover of the mobile phone arrives at the coating mechanism 2 area via the conveyor platform 5, the motor 4 is started to rotate the eccentric shaft 201 at its output end. The other end of the eccentric shaft 201 is the limiting shaft 202, which moves the pull rod 203 horizontally back and forth, pushing the pull rod 203 horizontally left and right. During the process, the rotating shaft 1 204 and the rotating shaft 206 are both rotated and connected to the top of the inner wall of the outer box 1. At this time, the lever 1 205 will swing the clamping block 207 at the other end under the action of the pull rod 203. Since the clamping block 207 is also fixed with the lever 209, the lever 209 swings synchronously while the lever 1 205 swings. At the bottom of the clamping block 207, there is a coating plate 208. At this time, the coating plate 208 will perform swing coating on the back cover of the mobile phone, thereby improving the efficiency of the coating work on the back cover of the mobile phone and reducing the cost. Furthermore, the protective mechanism 3 can prevent the back covers of mobile phones on the conveyor platform 5 from colliding due to increased workload in a short period of time. The cylinder 302, which is fixed in the fixed box 301 at the bottom of the middle of the conveyor platform 5, receives a signal and pushes the baffle 305 upward through the fixed plate 303. The baffle 305 blocks the subsequent back covers of mobile phones on the conveyor platform 5. During the process, the guide rods 304 on both sides of the fixed plate 303 can guide the pushing path of the cylinder 302 to avoid misalignment. When normal operation is resumed, the cylinder 302 pulls the baffle 305 downward. At this time, the roller 307 between the stabilizing blocks 306 at the top of the baffle 305 is placed in the middle of the conveyor platform 5, which can restore the conveying of the back covers of mobile phones and greatly improve the damage rate of the back covers of mobile phones during the coating process.
