Description

Technical Field

[0001] This utility model relates to the field of automated processing equipment, and in particular to an automated surface processing equipment for mobile phone frames. Background Technology

[0002] In the manufacturing process of modern electronic products, the surface treatment of the mobile phone frame (such as polishing, spraying, and inspection) is a crucial step in ensuring the product's appearance quality and functionality. Existing mobile phone frame surface treatment equipment typically suffers from the following structural deficiencies in practical applications: Firstly, regarding workpiece fixation, most equipment uses pneumatic or hydraulic clamping structures that are relatively fixed and difficult to adapt flexibly to different models and sizes of mobile phone frames. Operators need to frequently change clamps, which is not only time-consuming and labor-intensive, but also lacks precise clamping force control. When the clamping force is too large, it can easily damage or deform the surface of the frame; when the clamping force is insufficient, it will cause the workpiece to loosen during processing, affecting processing accuracy.

[0003] Secondly, regarding workpiece position adjustment and positioning, existing equipment typically relies on manual placement of the middle frame to its approximate position, followed by visual alignment by the operator or simple mechanical stops for limiting. This positioning method lacks a precise mechanical locking structure, failing to guarantee the accuracy and repeatability of each positioning. During high-speed or high-precision machining, even minor positional deviations and structural vibrations can lead to substandard final machining results. This is especially true in scenarios requiring multi-station or continuous machining, where the lack of a precise locking positioning structure severely restricts the accuracy and stability of automated machining.

[0004] Therefore, this utility model proposes an automated surface processing equipment for mobile phone frames to address the shortcomings of existing technologies. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automated surface processing equipment for mobile phone frames, aiming to improve the problems of existing automated surface processing equipment for mobile phone frames, such as the lack of adaptability of the clamping mechanism to frames of different sizes, the easy damage to the workpiece surface during the clamping process, and the lack of precise mechanical limit locking for workpiece positioning.

[0008] Preferably, the adjustment assembly further includes a screw and a locking block. The screw is threadedly connected to the inside of the slide plate, and the locking block is rotatably connected to the bottom end of the screw. The outer wall size of the locking block is adapted to the inner wall size of the limiting hole. The locking block can be inserted into the inside of the limiting hole. By tightening the screw, the locking block is driven to engage with the limiting hole, thereby achieving precise graded positioning and rigid locking of the slide plate.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Reference Figures 1-4This utility model provides an automated surface processing equipment for mobile phone frames, which aims to solve the problems in the prior art, such as the lack of adaptive adjustment capability of the clamping mechanism for frames of different sizes, easy damage to the workpiece surface during the clamping process, and lack of precise mechanical limiting structure for workpiece positioning.

[0020] This automated surface processing equipment for mobile phone frames includes a base 1, a sliding plate 2, a clamping assembly 3, an adjusting assembly 4, and a processing device 5. The sliding plate 2 is slidably connected to the top of the base 1. The base 1 serves as the basic support platform for the entire equipment, providing a mounting base for the sliding plate 2, the adjusting assembly 4, and the processing device 5. The sliding plate 2, positioned above the base 1, can reciprocate along its length on the top of the base 1, used for initial position adjustment of the clamping assembly 3. The clamping assembly 3, located on top of the sliding plate 2, is the core mechanism for clamping and positioning the mobile phone frame. The adjusting assembly 4, positioned between the base 1 and the sliding plate 2, is used to precisely lock and limit the sliding position of the sliding plate 2. The processing device 5, mounted on top of the base 1, is the execution mechanism for processing the surface of the mobile phone frame.

[0021] The clamping assembly 3 includes a receiving plate 303, an electric push rod 302, a fixing rod 304, a connector 305, a rotating rod 306, and a clamping plate 307. The receiving plate 303 is fixedly installed on the top of the slide plate 2, serving as the mounting base for the clamping assembly 3. The electric push rod 302 is fixedly installed on the outer side wall of the receiving plate 303, serving as the power source for opening and closing the clamping plate 307. The fixing rod 304 is fixedly installed on the front side wall of the receiving plate 303, serving as a stable fulcrum when the clamping plate 307 rotates.

[0022] The output end of the electric push rod 302 is fixedly connected to one end of the connector 305, and the other end of the connector 305 is rotatably connected to one end of the rotating rod 306. The other end of the rotating rod 306 is rotatably connected to the outer wall of the clamping plate 307. The outer wall of the clamping plate 307 near the receiving plate 303 is rotatably connected to the end of the fixed rod 304. When the electric push rod 302 extends or retracts, it drives the connector 305 to perform linear reciprocating motion. The connector 305 pushes the rotating rod 306 to swing, and the swing of the rotating rod 306 further drives the clamping plate 307 to perform opening and closing motion around the rotation axis of the fixed rod 304, thereby realizing the clamping and releasing of the mobile phone frame. The fixed rod 304 plays a key role as a rotation fulcrum in this structure, ensuring the stability and accuracy of the movement of the clamping plate 307.

[0023] The adjusting component 4 is used to adjust and lock the sliding position of the slide plate 2 on the base 1. It includes a slide groove 402, a limiting hole 405, a screw 403, and a locking block 404. The slide groove 402 is formed on the top surface of the base 1, and the bottom of the slide plate 2 protrudes and slides within the slide groove 402. The slide plate 2 reciprocates linearly along the length of the slide groove 402 to achieve a coarse adjustment of the clamping position. The limiting hole 405 is formed on the inner bottom wall of the slide groove 402 and is evenly distributed in multiple sets along the length to provide a graded and precise locking position.

[0024] The screw 403 is threaded into the interior of the slide plate 2, and the locking block 404 is rotatably connected to the bottom end of the screw 403. When the operator rotates the screw 403, the screw 403 moves downward under the action of the thread, driving the locking block 404 to move downward synchronously. When the outer wall size of the locking block 404 matches the inner wall size of the limiting hole 405, the locking block 404 can be inserted into the limiting hole 405 to achieve rigid locking of the slide plate 2 on the base 1, effectively preventing displacement due to vibration during processing and ensuring processing accuracy.

[0025] In a preferred embodiment, the adjustment assembly 4 also includes a pull rod 401. The pull rod 401 is fixedly installed on the side wall of the slide plate 2. The pull rod 401 has a U-shaped structure. By applying force through the pull rod 401, the operator can more conveniently and stably drive the slide plate 2 to slide along the slide groove 402, so as to quickly move the clamping assembly 3 to the predetermined coarse adjustment position.

[0026] As another preferred embodiment, to provide cushioning and anti-slip properties during clamping and effectively prevent damage to the surface of the phone's mid-frame, the clamping assembly 3 also includes an elastic pad 308. The elastic pad 308 is fixedly bonded to the inner sidewall of the clamping plate 307 and directly contacts the phone's mid-frame. The elastic pad 308 is preferably made of polyurethane, which has good elasticity and wear resistance, and can provide flexible clamping force.

[0027] In another preferred embodiment, the clamping assembly 3 further includes a controller 301 for controlling the extension and retraction of the electric push rod 302. The controller 301 is fixedly mounted on the top of the electric push rod 302 and is electrically connected to the electric push rod 302 via a wire to achieve automated control of the clamping process.

[0028] In another preferred embodiment, the connector 305 is a plate-shaped structure. The connector 305 is coaxially fixed with the output shaft of the electric push rod 302. The connector 305 and the rotating rod 306 are hinged by a pin, which ensures the stability and reliability of the transmission process.

[0029] In another preferred embodiment, the processing device 5 is located in the middle of the base 1, and its processing head is suspended above the clamping plate 307. The processing device 5 can be a laser head, a spray nozzle, or a detection camera, etc., and is used for automated surface processing of the clamped mobile phone frame. Its placement makes full use of the operating space above the clamping plate 307 after it is opened and closed, which facilitates processing operations.

[0030] Working principle: When using this equipment, first place the base 1 on the construction template or the predetermined installation position. The slide plate 2 on the base 1 can slide along its length on the base 1 to adjust the initial position of the clamping component 3. The receiving plate 303 is fixed on the slide plate 2 as the mounting base of the clamping component 3. When it is necessary to clamp and position the mobile phone frame, the operator activates the controller 301 in the clamping component 3. The controller 301 drives the electric push rod 302 to extend or retract. The extension and retraction of the electric push rod 302 causes the connecting piece 305 fixed to it to perform linear reciprocating motion. 05 is connected to the rotating rod 306. The rotating rod 306 swings under the action of the electric push rod 302. Due to the setting of the fixed rod 304, the clamping plate 307 can be limited and protected. The swing of the rotating rod 306 further drives the clamping plate 307 to rotate around the end connected to the fixed rod 304 and the rotating rod 306 as the axis, closing or opening towards the object. Thus, the clamping degree can be flexibly adjusted according to different types of mobile phone frames. The inner side of the clamping plate 307 is provided with an elastic pad 308, which provides buffering and anti-slip effect during clamping, effectively avoiding damage to the surface of the embedded part and enhancing the clamping stability.

[0031] After the clamping plate 307 is clamped, the position of the mobile phone frame can be precisely adjusted by adjusting the component 4. First, the slide plate 2 is slid along the track of the slide groove 402 by the pull rod 401. When it slides to the desired position, the screw 403 is rotated to make it move downward inside the slide plate 2, while driving the locking block 404 to move together. When the locking block 404 moves downward synchronously and engages inside the limiting hole 405, the running trajectory of the slide plate 2 can be controlled to achieve the effect of limiting and fixing. By adjusting the distance between each slide plate 2, the relative position of the workpiece can be adjusted. After the position of the mobile phone frame is adjusted appropriately, the processing equipment 5 is started to process it.

[0032] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that performs control functions, and the existing publicly available power connection technologies are not described in detail in the text.

[0033] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
