Description

Technical Field

[0001] The utility model relates to the field of detection technology, in particular to a device for visually detecting surface defects of a mobile phone screen. Background Art

[0002] The mobile phone screen inspection process on the existing production line is manual inspection through the naked eye. However, manual inspection is very inefficient, time-consuming and labor-intensive, with high labor costs. In addition, due to the large differences in manual inspection, the inspection results are unstable, making it difficult to ensure that the inspected mobile phone screens fully meet normal standards. The existing automatic inspection machines for mobile phone screens are also not perfect. They can only put one screen on for inspection, then take it off and put another on for inspection. The inspection efficiency is also not high.

[0003] Existing technology, such as the utility model mobile phone screen defect detection device, authorized by publication number CN221807029U, utilizes a circular turntable to allow placement and removal of mobile phone screens before and after testing to occur at the same location. This allows a single operator to manage both unloading and unloading of the test device, saving labor. Multiple fixing slots can be used to secure multiple mobile phone screens. Combined with multiple detection mechanisms, multiple visual systems can simultaneously capture and detect surface defects on the underlying mobile phone screens, achieving high-efficiency defect detection.

[0004] At present, there is still a lack of a device that can facilitate continuous testing of mobile phone screens and pick out defective mobile phone screens, and use a separate conveyor belt mechanism to transport them for collection. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a visual inspection device for surface defects of mobile phone screens, which is convenient for continuous inspection of mobile phone screens and can select mobile phone screens with defects and transmit them using a separate conveyor belt mechanism for collection.

[0006] The utility model adopts the following technical solutions to achieve the purpose of the utility model:

[0007] A device for visually inspecting mobile phone screen surface defects features a mounting plate fixedly connected to a horizontal linear module via a set of brackets; a vertical linear module fixedly connected to the slider of the horizontal linear module; a mounting ring fixedly connected to the slider of the vertical linear module; a cover fixedly connected to the mounting ring; an industrial camera fixedly connected to the top plate of the cover; and at least one conveyor belt mechanism fixedly connected to the mounting plate. By using the industrial camera, the surface of the mobile phone screen can be inspected for defects, facilitating further processing.

[0008] As a further limitation of this technical solution, the cover is fixedly connected to a circular ring, which is provided with a set of cross slots, each of which is provided with a cross block, each of which is fixedly connected to a mounting base, and each of which is fixedly connected to a clamping plate. By using the clamping plate, when the conveyor belt mechanism transports a mobile phone, the vertical linear module moves downward, causing the clamping plate to contact the conveyor belt, thereby limiting the position of the mobile phone and facilitating industrial camera inspection.

[0009] As a further limitation of this technical solution, the annular bearing is connected to a swivel, which is provided with a set of evenly distributed inclined slots, each of which is provided with a round block, and each round block is fixedly connected to a corresponding cross block. When the swivel rotates, the set of clamping plates are synchronized, which is convenient for use.

[0010] As a further limitation of this technical solution, the ring is fixedly connected to the motor via a motor bracket, the output shaft of the motor is fixedly connected to a gear, the rotating ring is fixedly connected to a ring gear, and the gear meshes with the ring gear. The motor drives the rotating ring and the gear and ring gear mesh, providing power for the movement of the rotating ring.

[0011] As a further limitation of this technical solution, the two oppositely disposed clamping plates are respectively fixedly connected to a cylinder, and the piston rods of the symmetrical cylinders are respectively fixedly connected to a long clamping plate. By using the cylinders and the long clamping plates, mobile phones can be conveniently clamped and defective mobile phones can be transferred to corresponding conveyor belt mechanisms for collection.

[0012] As a further limitation of the present technical solution, the long clamping plate is arranged parallel to the conveyor belt mechanism.

[0013] As a further limitation of the present technical solution, the cover is made of transparent material to facilitate detection by an industrial camera.

[0014] Compared with related technologies, the mobile phone screen surface defect visual inspection device provided by the present invention has the following beneficial effects:

[0015] (1) This device uses an industrial camera to detect the surface of the mobile phone screen to see if there are any defects on the surface, so as to facilitate the next step of processing;

[0016] (2) This device uses a clamping plate. When the conveyor belt mechanism transports the mobile phone, the vertical linear module moves downward so that the clamping plate contacts the conveyor belt, thereby limiting the position of the mobile phone and facilitating industrial camera detection;

[0017] (3) This device uses a cylinder and a long clamp to easily clamp the mobile phone, and transfers the defective mobile phone to the corresponding conveyor belt mechanism for collection. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1: A device for visually inspecting mobile phone screen surface defects comprises: a mounting plate 1 fixedly connected to a horizontal linear module 4 via a set of brackets 3; a vertical linear module 5 fixedly connected to the slider of the horizontal linear module 4; a mounting ring 6 fixedly connected to the slider of the vertical linear module 5; a cover 7 fixedly connected to the mounting ring 6; an industrial camera 9 fixedly connected to the top plate of the cover 7; and at least one conveyor belt mechanism 2 fixedly connected to the mounting plate 1. By using the industrial camera 9, the surface of the mobile phone screen can be inspected for defects, facilitating further processing.

[0027] The conveyor belt mechanism 2 adopts existing technology, and its structure and working principle are well known to those skilled in the art and will not be described in detail here.

[0028] The model of the transverse linear module 4 is W60-35.

[0029] The model of the vertical linear module 5 is DS45S75C.

[0030] The model of the industrial camera 9 is MV-CS200-10UC.

[0031] The cover 7 is fixedly connected to the ring 8, which is provided with a set of cross slots 15. Each cross slot 15 is provided with a cross block 16. Each cross block 16 is fixedly connected to a mounting seat 17, and each mounting seat 17 is fixedly connected to a clamping plate 18. By using the clamping plates 18, when the conveyor belt mechanism transports the mobile phone 2, the vertical linear module 5 moves downward, causing the clamping plates 18 to contact the conveyor belt, thereby limiting the position of the mobile phone and facilitating detection by the industrial camera 9.

[0032] The ring 8 is connected to the swivel 14 by a bearing. The swivel 14 is provided with a set of evenly distributed inclined slots 21. Each inclined slot 21 is provided with a round block 13. Each round block 13 is fixedly connected to a corresponding cross block 16. When the swivel 14 rotates, the group of clamping plates 18 are synchronized and easy to use.

[0033] The ring 8 is fixedly connected to the motor 10 through the motor bracket, the output shaft of the motor 10 is fixedly connected to the gear 11, and the rotating ring 14 is fixedly connected to the ring gear 12, and the gear 11 meshes with the ring gear 12. By using the motor 10 to drive and the gear and ring gear to mesh, the movement of the rotating ring 14 is powered.

[0034] The model of the motor 10 is 37GB555.

[0035] The horizontal linear module 4 , the vertical linear module 5 , the industrial camera 9 and the motor 10 are electrically connected to a controller respectively. The controller model is STM32F103VCT6.

[0036] The cover 7 is made of transparent material to facilitate detection by the industrial camera 9 .

[0037] The working principle of the mobile phone screen surface defect visual detection device provided by the utility model is as follows:

[0038] Conveyor mechanism 2 is equipped with a mobile phone placement marker, into which the phone is placed. A controller controls the coordinated movement of conveyor mechanism 2 and vertical linear module 5. When the phone moves into the area formed by clamping plate 18, the controller controls the vertical linear module 5 to move, causing clamping plate 18 to be in close contact with conveyor mechanism 2. The controller controls motor 10 to rotate, which drives gear 11, which in turn drives ring gear 12 and swivel 14. Swivel 14 drives circular block 13 along inclined slot 21, which in turn drives cross block 16 along cross slot 15. Cross block 16 drives mounting base 17 and clamping plate 18 to move, causing clamping plate 18 to clamp the four corners of the phone. The controller controls industrial camera 9 to operate and perform defect detection. After the detection is completed, motor 10 is controlled to rotate in the opposite direction, causing vertical linear module 5 to move in the opposite direction, moving clamping plate 18 away from conveyor mechanism 2.

[0039] Example 2: This example further elaborates on Example 1. Two opposing clamping plates 18 are each fixedly connected to a cylinder 19, and the piston rods of the symmetrical cylinders 19 are each fixedly connected to a long clamping plate 20. By using cylinders 19 and long clamping plates 20, mobile phones can be easily clamped and defective phones can be transferred to the corresponding conveyor belt mechanism 2 for collection.

[0040] The model of the cylinder 19 is MGJ10-15.

[0041] The cylinder 19 is electrically connected to the controller.

[0042] The long clamping plate 20 is arranged parallel to the conveyor belt mechanism 2 .

[0043] The surface material of the long plywood 20 and the plywood 18 is rubber.

[0044] The working principle of the mobile phone screen surface defect visual detection device provided by the utility model is as follows:

[0045] When there is a defect in the mobile phone, the control cylinder 19 is extended to make the long splint 20 clamp the mobile phone. The controller controls the vertical linear module 5 and the horizontal linear module 4 to move, so that the long splint 20 drives the mobile phone to move to another conveyor belt mechanism 2, and controls the vertical linear module 5 and the horizontal linear module 4 to move, so as to realize the reset of the industrial camera 9.

Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
