Description

Technical Field

[0001] This utility model relates to the field of mobile phone casing inspection technology, and in particular to a special inspection device for mobile phone manufacturing production lines. Background Technology

[0002] Manual inspection not only leads to high labor costs, but is also prone to missed inspections and misjudgments due to factors such as personnel fatigue and differences in operating procedures. Especially in precision inspection scenarios such as screen scratches and component assembly deviations, the problem of missed inspections by manual inspection seriously affects the stability of product quality. Even some inspection equipment that adopts machine vision is mostly a single-function module, lacking coordinated design with conveying and lifting mechanisms, and cannot achieve a semi-automated closed loop in the inspection process.

[0003] Traditional inspection devices typically employ fixed clamping structures, allowing inspection of only a single surface of the workpiece. For complex areas such as the sides or curved surfaces of a mobile phone, multiple manual flipping or adjustments to the workpiece's orientation are necessary for comprehensive inspection. This method not only increases process time and reduces production line speed but also easily leads to decreased inspection accuracy due to positioning deviations during the flipping process. Furthermore, manual adjustments cannot cover all angles, leaving hidden areas such as the phone casing joints and button gaps as blind spots, making it impossible to effectively identify defects such as scratches and assembly misalignments.

[0017] Reference Figure 1-6 This utility model discloses a special inspection device for mobile phone manufacturing production lines, comprising a T-shaped support plate 12, a U-shaped support plate 13 fixedly connected to the T-shaped support plate 12, a third motor 14 fixedly connected to the T-shaped support plate 12, a third rotating shaft 15 fixedly connected to the output end of the third motor 14 and passing through the side wall of the U-shaped support plate 13, a housing 16 fixedly connected to the third rotating shaft 15, a second slide rail 18 fixedly connected to the inner side wall of the housing 16, a clamping plate 19 movably connected to the second slide rail 18, a pressure sensor 21 fixedly connected to the groove on the contact surface of the clamping plate 19, a hydraulic device 20 fixedly connected to the inner wall of the housing 16, the other end of the hydraulic device 20 fixedly fixed to the housing 16, a fourth rotating shaft 17 fixedly connected to the outer side wall of the other end of the housing 16, the fourth rotating shaft 17 inserted into the U-shaped support plate 13 and movably connected, and a detection camera 22 fixedly connected to the U-shaped support plate 13.

[0018] Specifically, the third motor 14 can be a NEMA17 stepper motor. Its working principle is to control the energizing sequence of the stator windings through pulse signals, converting the electrical pulses into precise angular and linear displacements. With the assistance of the third rotating shaft 15 and the fourth rotating shaft 17, it achieves the rotation of the housing 16. The housing 16 serves as the outer shell of the clamping component. The pressure sensor 21 can be an MS5837-30BA digital pressure sensor. Its working principle is to sense pressure through the MEMS silicon piezoresistive effect, and after internal signal processing, feed back the pressure as a digital signal. When the phone case comes into contact with the clamping plate 19, the pressure sensor 21 reaches the maximum preset bearing value and feeds back data. The external controller then stops the hydraulic unit 20 to prevent damage to the phone case. The second slide rail 18 is used to assist the clamping plate 19 in moving. The detection camera 22 can be a Medvision MV-XGC6500GM industrial camera. Through the coordinated work of global shutter capture, multi-source illumination, 10 Gigabit Ethernet transmission and intelligent algorithm analysis, it can achieve high-speed, high-precision, and fully automatic detection of scratches on the surface of the phone case. The top and bottom surfaces of the housing 16 are open.

[0019] A base 1 is provided below the U-shaped support plate 13. A first support plate 2 is fixedly connected to the base 1. A first rotating shaft 3 is movably connected to the first support plate 2. A conveyor belt 4 is sleeved on the first rotating shaft 3. A key block 5 is fixedly connected to the conveyor belt 4.

[0020] Specifically, the spacing between key blocks 5 must be greater than the width of housing 16.

[0021] A first motor 6 is fixedly connected to the base 1, and a second rotating shaft 7 is fixedly connected to the output end of the first motor 6. The first rotating shaft 3 passes through the first support plate 2 at one point and is fixedly connected to the second rotating shaft 7.

[0022] Specifically, the first motor 6 can use a 34HS31-5504D stepper motor. The stepper motor works based on the law of electromagnetic induction and the principle of magnetic pole interaction, which accurately converts electrical pulse signals into angular displacement.

[0023] A second support plate 8 is fixedly connected to the base 1. A first slide rail 11 is fixedly connected to the side wall of the center slot of the second support plate 8. A second motor 9 is fixedly connected to the top of the second support plate 8.

[0024] Specifically, the second motor 9 can use 57HS13-3004S, whose core operation is based on the law of electromagnetic induction and the principle of magnetic field interaction, accurately converting electrical pulse signals into angular displacement.

[0025] A lead screw 10 is fixedly connected to the output end of the second motor 9. The lead screw 10 passes through the second support plate 8 from the top and is located at the center slot.

[0026] Specifically, the second motor 9 can control the T-shaped support plate 12 to move up and down via the lead screw 10 and the first slide rail 11.

[0027] The T-shaped support plate 12 is movably connected to the first slide rail 11.

[0028] Specifically, the first slide rail 11 plays a role in restraining and assisting traction when the T-shaped support plate 12 moves.

[0029] The lead screw 10 passes through the T-shaped support plate 12 and is connected by a screw.

[0030] Specifically, the spiral profile of the lead screw 10 has self-locking properties, which can prevent the T-shaped support plate 12 from slipping off.

[0031] Working principle: The worker places the mobile phone casing between the two key blocks 5 on the conveyor belt 4. The first motor 6 is started, driving the first rotating shaft 3 on the second rotating shaft 7 to rotate. Under the action of friction, the conveyor belt 4 runs and stops when it reaches the preset program position. The second motor 9 is started, driving the lead screw 10 to rotate. With the assistance of the first slide rail 11, the T-shaped support plate 12 moves downward and stops when it reaches the preset position. At this time, the housing 16 frames the mobile phone casing. The hydraulic device 20 is started, and with the assistance of the second slide rail 18, the clamping plate 19 moves. When the clamping plate 19 contacts the mobile phone casing, the pressure sensor 21 is pressed. When the preset maximum value is reached, the pressure sensor 21 is pressed. A signal is sent to the external controller to stop the hydraulic press 20, completing the clamping operation. The second motor 9 is restarted to lift the clamping component, and the detection camera 22 is activated for detection. Simultaneously, the third motor 14 is activated, and with the assistance of the third rotating shaft 15 and the fourth rotating shaft 17, the housing 16 and the internal clamping component are controlled to rotate and perform multi-angle detection. After the detection is completed, the phone casing is returned to its original position, and the clamping component is released to complete the detection. If a defective product is found during the detection process, an external alarm is triggered, and the defective product is manually removed. Other steps and parts are detected according to existing conventional technology.
