Description

Knapsack clamp type testing mechanism Technical Field The utility model relates to the technical field of test equipment, in particular to a backpack clamp type test mechanism. Background Bare screen testing generally refers to the functional and visual inspection of a display screen without housing protection (i.e., a so-called "bare screen") during electronic device manufacturing or repair. Such tests are mainly used to confirm whether the screen has any manufacturing defects, transport damage or post-repair problems. Bare screen testing may cover a variety of detection aspects. However, in the actual operation process, the bare screen is extremely easy to be influenced by external impact or vibration in the carrying and testing links due to the structural characteristics of the bare screen, so that damage conditions such as bruise, scratch, breakage and the like occur. Especially in the process of transferring from a storage or transport container to a testing device, if effective fixing and buffering protection measures are lacking, the bare screen is more easily damaged accidentally due to improper operation or mismatching of equipment. This not only reduces product yield but also significantly increases testing costs and rework risks for the enterprise. In addition, frequent damage also can prolong test period, influence whole production efficiency to lead to the fact the chain to influence to follow-up assembly flow, inconvenient use. Disclosure of utility model The utility model aims to provide a knapsack clamp type testing mechanism, which can avoid the problem that in actual operation, a bare screen is easy to be impacted or vibrated in the process of carrying and testing to cause bruise, scratch and even fracture due to fragile structure. Particularly, when the test device is transported, if effective fixing and buffering measures are not available, the damage risk is higher, the yield is affected, and the test cost and the rework rate are increased. The utility model provides a backpack clamp type testing mechanism which comprises a protection box, wherein a first limiting assembly is arranged at the top of the protection box, the first limiting assembly comprises a lower cover plate, fixed blocks are fixedly connected to the front side and the rear side of the top of the lower cover plate, buckles are commonly connected to the outer surfaces of the fixed blocks and the protection box, a second limiting assembly is arranged in an inner cavity of the protection box, the second limiting assembly comprises four rotating rods, and a first push plate is fixedly connected to the outer surfaces of the rotating rods. In a specific embodiment, the rear side at the top of the lower cover plate is hinged with an upper cover plate, the opposite sides of the upper cover plate and the lower cover plate are respectively provided with a placing cavity, and the upper cover plate and the lower cover plate are movably connected. In a specific embodiment, the outer surface of the first push plate is connected with a long rod, and the left side and the right side of the inner cavity of the protection box are both in sliding connection with clamping plates. In a specific embodiment, the front side and the rear side of the clamping plate are both provided with sliding cavities, and the sliding cavities are in sliding connection with the outer surface of the clamping plate. In a specific embodiment, the left side and the right side of the front side of the protection box are fixedly connected with a mounting box, and an inner cavity of the mounting box is slidably connected with a movable disc. In a specific embodiment, the bottom of the movable disk is fixedly connected with a clamping rod, and the top of the inner cavity of the installation box and the top of the movable disk are respectively fixedly connected with a fixing rod. In a specific embodiment, the outer surface of the fixed rod is sleeved with a reset spring, and two ends of the reset spring are respectively connected with the top of the inner cavity of the protection box and the top of the movable disc. In a specific embodiment, the outer surface of the clamping rod is fixedly connected with a second push plate, and the outer surface of the rotating rod is provided with a plurality of locking holes matched with the clamping rod. The protective box has the beneficial effects that the bare screen can be firmly fixed in the jig through the cooperative cooperation of the protective box, the first limiting assembly and the second limiting assembly, the non-display area and the frame part with fragile periphery of the bare screen are effectively wrapped and protected, damage caused by external force impact or friction in the carrying or testing process is avoided, the safety of the bare screen in the transferring process is improved, the operation of wiring, detection and the like by operators is facilitated, and the testing efficiency is improved.
