Description

Technical Field

[0001] This utility model relates to the field of mobile phone shielding cover testing technology, and in particular to an optical screening machine for mobile phone shielding covers. Background Technology

[0002] Mobile phone shielding cover testing is a professional inspection of the quality and performance of the internal shielding cover of a mobile phone. The shielding cover plays a crucial role in shielding against electromagnetic interference and protecting the stable operation of internal circuits. The testing typically covers shielding effectiveness (its ability to block electromagnetic waves); appearance quality (checking for defects such as deformation, damage, and burrs); dimensional accuracy (ensuring precise matching with the internal structure of the phone); and material composition analysis (ensuring the materials meet design requirements).

[0003] During the dimensional inspection of mobile phone shielding covers using an optical sorting machine, the shielding covers are typically transported via a conveyor system, and then scanned from all angles by a high-definition camera. The acquired image information is rapidly transmitted to the system, which then identifies various dimensional parameters to determine whether the shielding cover meets quality standards.

[0004] The shortcomings of the above-mentioned existing technical solutions are that, during the inspection process, since the shielding cover has two sides, scanning only one side cannot fully obtain its appearance and size information, which requires flipping the shielding cover and scanning it a second time, thus reducing the inspection efficiency. Utility Model Content

[0005] This invention provides an optical screening machine for mobile phone shielding covers, which solves the problem in the prior art that mobile phone shielding cover optical screening machines require flipping operations and secondary scanning during testing, thus reducing testing efficiency.

[0006] An optical sorting machine for mobile phone shielding covers includes a double-track conveyor belt for conveying mobile phone shielding covers, a high-precision camera lens for detecting the external shape of the mobile phone shielding cover is arranged above the double-track conveyor belt, and a flipping mechanism for flipping the mobile phone shielding cover is arranged in the middle of the double-track conveyor belt.

[0007] As a further embodiment of this utility model: the flipping mechanism includes a placement box that is fitted in the middle of a double-track conveyor belt. Positioning blocks are fixedly arranged on both sides of the upper surface of the placement box. A pneumatic nozzle is arranged between the two sets of positioning blocks. The pneumatic nozzle is inclined upward. A flexible air supply pipe is connected to the bottom of the pneumatic nozzle. A solenoid valve is provided on the air supply pipe. An air supply device is connected to the other end of the air supply pipe.

[0008] As a further embodiment of this utility model: the pneumatic nozzle is rotatably disposed between two sets of positioning blocks, and a rotating shaft is fixedly disposed on both sides of the pneumatic nozzle and rotatably disposed with the positioning block. A locking bolt for pressing the rotating shaft at the corresponding position and positioning the tilt angle of the pneumatic nozzle is threadedly connected to one set of the positioning blocks.

[0009] As a further embodiment of this utility model: another set of positioning blocks is provided with an angle comparison dial, the angle comparison dial is marked with an angle range, and a pointer that matches the angle range is rotatably arranged in the middle of the angle comparison dial, and the rotating shaft and the pointer connection end are coaxially and fixedly connected.

[0010] As a further embodiment of this utility model: the placement box is provided with a positioning component for fixing the placement box between the double-track conveyor belts.

[0011] As a further embodiment of this utility model: the positioning component includes a rotating block fixedly disposed inside the placement box and two sets of coaxially fixedly connected threaded rods with opposite thread directions. The two sets of threaded rods are rotatably connected to the rotating block in the middle. Each set of threaded rods is threadedly connected to a threaded slider. Each set of threaded sliders is movably connected to push rods on both sides. The placement box has top openings on both sides. Each set of top openings has a push block slidably fitted inside. The push rods on both sides of the threaded sliders are movably connected to the corresponding push blocks. A drive component for driving the two sets of threaded rods to rotate is provided on one side of the placement box.

[0012] As a further embodiment of this utility model: the driving assembly includes an internal hexagon screw rotatably connected to one end of the placement box, and the internal hexagon screw is coaxially and fixedly connected to a set of threaded rods.

[0013] As a further embodiment of this utility model, a rubber pad is provided on the outer side of the push block.

[0014] As a further embodiment of this utility model: the width of the placement box is the same as the gap between the tracks of the double-track conveyor belt.

[0015] As a further embodiment of this utility model, the pneumatic nozzle is fixedly connected to the positioning block.

[0016] The beneficial effects of this utility model are:

[0017] 1. In use, this utility model automates the flipping process of mobile phone shielding covers during inspection by incorporating a flipping mechanism. A dual-track conveyor belt transports the mobile phone shielding covers. When the covers reach the flipping mechanism, a pneumatic nozzle, after the solenoid valve is opened, uses a high-speed airflow to obliquely blow the front end of the shielding cover, causing it to flip backward and fall laterally onto the conveyor belt. This process requires no manual intervention, greatly improving inspection efficiency and reducing the time spent on manual flipping, making the entire inspection process more efficient and economical.

[0018] 2. In use, the pneumatic nozzle in the flipping mechanism is rotatably positioned between two sets of positioning blocks, and its tilt angle can be precisely adjusted via locking bolts and an angle comparator dial, ensuring that the airflow accurately and effectively flips the mobile phone shield. This adjustability improves the versatility and adaptability of the equipment, meeting the testing needs of various types of mobile phone shields and enhancing its practical value.

[0026] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0027] like Figures 1 to 5 As shown in the figure, an embodiment of this utility model provides an optical screening machine for mobile phone shielding covers, including a double-track conveyor belt 1 for conveying mobile phone shielding covers. A high-precision camera lens 2 is suspended above the double-track conveyor belt 1 by a support frame, and the lens is used to detect the external shape of the mobile phone shielding cover. A flipping mechanism 3 for flipping the mobile phone shielding cover is provided in the middle of the double-track conveyor belt 1.

[0028] Specifically, the flipping mechanism 3 includes a placement box 301, which is fitted into the middle of the double-track conveyor belt 1. Positioning blocks 302 are fixedly installed on both sides of the upper surface of the placement box 301, and a pneumatic nozzle 303 is positioned between the two sets of positioning blocks 302. The pneumatic nozzle 303 is angled upwards, as... Figure 3 As shown, a flexible gas supply pipe 304 is connected to the bottom of the device, and the other end of the gas supply pipe 304 is connected to a gas supply device, such as a gas storage tank or other gas compression equipment, all of which fall within the protection scope of this patent. In actual operation, the dual-track conveyor belt 1 moves the mobile phone shielding cover closer to the high-precision camera lens 2, thereby enabling the inspection of the shape and size of the upper part of the mobile phone shielding cover. A solenoid valve can be installed on the gas supply pipe 304. When it is necessary to flip the mobile phone shielding cover, the solenoid valve opens, and the high-speed airflow blows obliquely at the front end of the mobile phone shielding cover, causing the front end of the mobile phone shielding cover to flip backward and fall laterally onto the dual-track conveyor belt 1. In this way, the high-precision camera lens 2 can inspect the bottom of the mobile phone shielding cover.

[0029] Furthermore, in one specific embodiment, the pneumatic nozzle 303 is rotatably mounted between two sets of positioning blocks 302. Rotating shafts, rotatably connected to the positioning blocks 302, are fixedly mounted on both sides of the pneumatic nozzle 303. A locking bolt 305 is threaded onto one set of positioning blocks 302, which is used to press the rotating shaft at the corresponding position to position the tilt angle of the pneumatic nozzle 303. An angle comparator dial 306 is mounted on the other set of positioning blocks 302, with an angle range marked on it. A pointer 307, corresponding to the angle range, is rotatably mounted in its center, and the connecting end of the rotating shaft and the pointer 307 is coaxially and fixedly connected. Before formal use, the output direction of the pneumatic nozzle 303 needs to be adjusted to ensure that the tilt angle of the pneumatic nozzle 303 is between 45° and 60°. The specific tilt angle needs to be determined based on the shape and weight of the mobile phone shielding cover, as well as the results of repeated testing. After determining the angle, rotate the locking bolt 305. The locking bolt 305 presses against the rotating shaft, and the rotating shaft is locked by friction, thereby locking the tilt angle of the pneumatic nozzle 303.

[0030] In another specific embodiment, to ensure that the flipping mechanism 3 does not shift during use, a positioning component 308 is provided inside the placement box 301 to fix the placement box 301 between the double-track conveyor belts 1. Specifically, the positioning component 308 includes a rotating block 3081 fixedly disposed inside the placement box 301 and two sets of coaxially fixedly connected threaded rods 3082 with opposite thread directions. The two sets of threaded rods 3082 are rotatably connected to the rotating block 3081 in the middle. Each set of threaded rods 3082 is threadedly connected to a threaded slider 3083, and each set of threaded sliders 3083 is movably connected to both sides of a push rod 3084. The placement box 301 has top openings 3086 on both sides, and each set of top openings 3086 has a push block 3085 slidably fitted inside. The push rods 3084 on both sides of the threaded sliders 3083 are movably connected to the corresponding push blocks 3085. One end of the placement box 301 is rotatably connected to an internal hex screw 3087, which is coaxially fixed to a set of threaded rods 3082. An operator can use an Allen wrench to rotate the hex screw 3087, thereby rotating the two sets of threaded rods 3082, causing the two sets of threaded sliders 3083 on the two sets of threaded rods 3082 to move closer or further apart. When the two sets of threaded sliders 3083 move closer together, they press against the push rod 3084, which in turn pushes the push block 3085 outward along the top opening 3086, pressing against the track plate of the double-track conveyor belt 1 to fix the placement box 301. When the two sets of threaded sliders 3083 move further apart, they pull against the push rod 3084, which in turn moves the push block 3085 inward along the top opening 3086, causing the push block 3085 to retract into the top opening 3086, facilitating the removal of the placement box 301.

[0031] To ensure effective positioning, a rubber pad can be installed on one side of the push block 3085 to increase friction and improve stability. Additionally, the width of the placement box 301 is preferably the same as the gap between the rails of the double-track conveyor belt 1, which further ensures the stability of the placement box 301 during installation.

[0032] In another specific implementation, the pneumatic nozzle 303 is fixedly connected to the positioning block 302. In this case, when installing the flipping mechanism 3, the operator does not need to adjust the angle of the pneumatic nozzle 303, but only needs to adjust the position of the placement box 301, making the operation simpler and more convenient.

[0033] Working principle: Before testing, the operator adjusts the tilt angle of the pneumatic nozzle 303 to between 45° and 60° based on the shape, weight, and other characteristics of the mobile phone shielding cover, and referring to repeated test results. After adjustment, the locking bolt 305 is rotated to lock the angle. During installation, the operator uses an Allen wrench to rotate the Allen screw 3087, which drives the threaded rod 3082 to rotate, causing the threaded slider 3083 to move. This, in turn, pushes the push block 3085 outward along the top opening 3086, pressing against the track plate of the double-track conveyor belt 1 and firmly fixing the placement box 301, thus completing the fixation of the pneumatic nozzle 303.

[0034] The dual-track conveyor belt 1 is started, and mobile phone shielding covers are sequentially sent onto the dual-track conveyor belt 1, transporting the mobile phone shielding covers to be tested to below the high-precision camera lens 2. During the transport process, the mobile phone shielding covers first pass through the detection area of ​​the high-precision camera lens 2, at which time the high-precision camera lens 2 detects the upper shape and size of the mobile phone shielding covers.

[0035] When the phone shield needs to be flipped over to inspect its bottom, the solenoid valve on the air supply pipe 304 opens, and the air supply device delivers high-speed airflow to the pneumatic nozzle 303 through the flexible air supply pipe 304. The airflow blows obliquely at the front end of the phone shield, causing it to flip backward and fall laterally onto the dual-track conveyor belt 1. After flipping, the phone shield re-enters the inspection area of ​​the high-precision camera lens 2, enabling the inspection of the bottom of the phone shield.

[0036] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
