Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a backpack clip-type testing mechanism. Background Technology

[0002] Bare screen testing typically refers to the functional and aesthetic inspection of a display screen (i.e., a "naked screen") without a protective casing during the manufacturing or repair of electronic devices. This testing is primarily used to confirm the absence of any manufacturing defects, shipping damage, or post-repair issues. Bare screen testing can cover a variety of inspection aspects.

[0003] However, in actual operation, due to their structural characteristics, bare screens are highly susceptible to external impacts or vibrations during handling and testing, resulting in damage such as dents, scratches, and cracks. Especially during the transfer from storage or transport containers to testing equipment, without effective securing and cushioning measures, bare screens are more prone to accidental damage due to improper handling or equipment incompatibility. This not only reduces product yield but also significantly increases testing costs and rework risks for companies. Furthermore, frequent damage extends testing cycles, impacts overall production efficiency, and creates a chain reaction affecting subsequent assembly processes, making them unusable. Utility Model Content

[0004] The purpose of this invention is to provide a backpack-style testing mechanism that avoids the problems that occur in actual operation. Bare screens, due to their fragile structure, are easily damaged by impacts or vibrations during handling and testing, leading to dents, scratches, or even breakage. Especially when transported to the testing device, the lack of effective fixing and cushioning measures further increases the risk of damage, affecting not only yield but also increasing testing costs and rework rates.

[0005] This utility model provides a backpack clip-type testing mechanism, including a protective box. The top of the protective box is provided with a first limiting component, which includes a lower cover plate. Fixing blocks are fixedly connected to the front and rear sides of the top of the lower cover plate. The fixing blocks and the outer surface of the protective box are connected together by a buckle. The inner cavity of the protective box is provided with a second limiting component, which includes four rotating rods. The outer surface of the rotating rods is fixedly connected with a first push plate.

[0006] In one specific implementation, an upper cover plate is hinged to the rear side of the top of the lower cover plate, and placement cavities are respectively opened on the opposite sides of the upper cover plate and the lower cover plate, and the upper cover plate and the lower cover plate are movably connected.

[0007] In one specific implementation, a long rod is connected to the outer surface of the first push plate, and clamping plates are slidably connected to both the left and right sides of the inner cavity of the protective box.

[0008] In one specific implementation, sliding cavities are provided on both the front and rear sides of the clamping plate, and the sliding cavities are slidably connected to the outer surface of the clamping plate.

[0009] In one specific implementation, mounting boxes are fixedly connected to both the left and right sides of the front of the protective box, and a movable disk is slidably connected to the inner cavity of the mounting box.

[0010] In one specific implementation, a locking rod is fixedly connected to the bottom of the movable disk, and a fixing rod is fixedly connected to the top of the inner cavity of the mounting box and the top of the movable disk, respectively.

[0011] In one specific implementation, a return spring is sleeved on the outer surface of the fixing rod, and the two ends of the return spring are respectively connected to the top of the inner cavity of the protective box and the top of the movable disk.

[0012] In one specific implementation, a second push plate is fixedly connected to the outer surface of the locking rod, and a plurality of locking holes adapted to the locking rod are provided on the outer surface of the rotating rod.

[0013] The beneficial effects of this application are as follows: Through the coordinated operation of the protective box, the first limiting component, and the second limiting component, the bare screen can be securely fixed inside the fixture, effectively wrapping and protecting its non-display area and the relatively fragile surrounding frame, preventing damage from external impacts or friction during handling or testing. This not only improves the safety of the bare screen during transportation but also facilitates wiring, testing, and other operations for operators, thus increasing testing efficiency. Furthermore, the overall structure has good portability, making it convenient to carry and reuse. Attached Figure Description

[0022] However, in practice, bare screens are fragile and easily damaged by impacts or vibrations during handling and testing, leading to scratches, dents, or even breakage. Especially when transported to testing equipment, the risk of damage is even higher without effective securing and cushioning measures, affecting yield rates and increasing testing costs and rework rates. Therefore, the inventors have developed a backpack-style testing mechanism. The protective box, in conjunction with the first and second limiting components, firmly secures the bare screen within the fixture, effectively protecting its non-display areas and fragile bezels, preventing damage during handling or testing. This design improves safety and testing efficiency while being portable, easy to carry, and reusable, thus solving the aforementioned shortcomings.

[0023] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] Please refer to Figures 1 to 6This utility model provides a backpack clip-type testing mechanism, including a protective box 1. The top of the protective box 1 has a through cavity and a first limiting component 2. The outer surface of the protective box 1 has several heat dissipation holes. The first limiting component 2 includes a lower cover plate 21, which is placed on the top of the protective box 1. Fixing blocks 22 are fixedly connected to the front and rear sides of the top of the lower cover plate 21. The fixing blocks 22 and the outer surface of the protective box 1 are connected by a buckle 23, thereby establishing an installation between the buckle 23 and the lower cover plate 21. This facilitates the user to quickly install and remove the first limiting component 2 from the protective box 1 using the buckle 23. The inner cavity of the protective box 1 is provided with a second limiting component 3, which includes... Four rotating rods 31 are provided, with the front end of the rotating rod 31 extending to the outside of the protective box 1, and the rear rotating rod 31 rotatably connected to the rear side of the inner cavity of the protective box 1. The area of ​​the front rotating rod 31 in contact with the protective box 1 is rotatably connected by a bearing. A first push plate 32 is fixedly connected to the outer surface of the rotating rod 31. An upper cover plate 24 is hinged to the rear side of the top of the lower cover plate 21. Placement cavities 25 are respectively opened on the opposite sides of the upper cover plate 24 and the lower cover plate 21, so as to facilitate the inspection of the bare screen placed in the protective box 1 through the placement cavity 25. The upper cover plate 24 and the lower cover plate 21 are movably connected. Specifically, the upper cover plate 24 and the lower cover plate 21 are respectively equipped with magnetic suction plates and other magnetic suction materials to ensure that the product carried does not loosen or fall off during operation. Personnel can also easily and quickly change products. The outer surfaces of the upper cover plate 24, lower cover plate 21, and protective box 1 are provided with several punch holes and cavities to facilitate the bare screen to complete the lighting test with the test host and to facilitate the connection of the corresponding wires for wiring. The outer surface of the first push plate 32 is connected to a long rod 33. The left and right sides of the inner cavity of the protective box 1 are slidably connected to clamping plates 34. The front and rear sides of the clamping plates 34 are provided with sliding cavities 35, and the sliding cavities 35 are slidably connected to the outer surface of the clamping plates 34. The left and right sides of the front side of the protective box 1 are fixedly connected to mounting boxes 36. The inner cavity of the mounting box 36 is slidably connected to a moving plate 37, and the bottom of the moving plate 37 is fixedly connected to a locking rod 38.

[0025] Please refer to Figures 2 to 6 A fixing rod 39 is fixedly connected to the top of the inner cavity of the mounting box 36 and the top of the moving disk 37, respectively. A return spring 310 is sleeved on the outer surface of the fixing rod 39, and the two ends of the return spring 310 are respectively connected to the top of the inner cavity of the protective box 1 and the top of the moving disk 37. A second push plate 311 is fixedly connected to the outer surface of the locking rod 38, and positioning cavities adapted to the second push plate 311 are opened on both the left and right sides of the mounting box 36. Several locking holes 312 adapted to the locking rod 38 are opened on the outer surface of the rotating rod 31.

[0026] Specifically, when the user places the bare screen into the protective box 1, he manually moves the second push plate 311 upward. The second push plate 311 drives the locking lever 38 to rise synchronously and squeezes the reset spring 310 during the movement. When released, the reset spring 310 uses its elasticity to automatically reset the second push plate 311 and the locking lever 38, thereby causing the locking lever 38 to disengage from the locking hole 312.

[0027] At this time, the user can manually rotate the rotating rod 31, which drives the long rod 33 to rotate synchronously. The long rod 33 pushes the clamping plate 34 to move laterally, thereby achieving limited clamping of bare screens of different widths and ensuring that they will not shake during placement and transportation.

[0028] In summary, the working principle of the backpack clip-type testing mechanism of this utility model embodiment is as follows: When the user transfers the bare screen to the testing host, the bare screen can be placed in the protective box 1, with the display area of ​​the bare screen facing upwards. After placement, the left and right sides of the bare screen are first clamped by the second limiting component 3. When testing the display area of ​​the bare screen, the user can manually flip the upper cover 24 to close it with the lower cover 21. Subsequently, the bare screen can be tested for relevant performance by the testing host. After the test is completed, the user manually flips the upper cover 24 again and releases the locking state of the buckle 23, separating the lower cover 21 from the protective box 1. After disassembly, the bare screen can be taken out of the protective box 1 for subsequent operations.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
