Description

Technical Field

[0001] The utility model relates to the technical field of positioning jigs, in particular to a positioning jig for assembling a power adapter. Background Art

[0002] The power adapter is responsible for converting external power into the specific voltage and current required by the device to ensure the normal operation of the equipment. The power adapter is usually an important component in electronic products. It needs to be accurately and firmly assembled into the main product. By using a positioning fixture, the operator can place the power adapter in the correct position and ensure that it is correctly connected to other components to avoid assembly errors and problems that may cause failures.

[0003] The positioning jig used in the power adapter assembly process needs to be manually fixed and loosened, which requires too much manual operation during use. As a result, it takes a long time to operate the jig during the power adapter assembly, which is time-consuming and cumbersome. For this reason, we propose a positioning jig for power adapter assembly to solve the existing problem. Utility Model Content

[0004] The utility model aims to solve the problems existing in the background technology and to provide a positioning fixture for assembling a power adapter.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a positioning fixture for assembling a power adapter, comprising a support plate, a mounting frame, a spring, a base plate, a negative pressure pump and a suction hood, wherein a symmetrically distributed support plate is arranged at the upper end of the base plate, a symmetrically distributed mounting frame is arranged between the support plates, and springs symmetrically distributed and connected to the support plates are arranged at opposite ends of the mounting frames, equidistantly distributed suction holes are opened inside the upper end of the base plate, a suction hood is arranged at the lower end of the base plate, a negative pressure pump is arranged at the lower end of the base plate, and a suction pipe is installed between the negative pressure pump and the suction hood.

[0006] Preferably, both ends of the installation frame are inclined outwards, and a travel opening is provided at the inclined portion of the installation frame. During the assembly process, the main assembly of the power adapter is placed between the installation frames by squeezing the travel opening.

[0007] Preferably, the installation frame is provided with equally spaced conveying rollers, the rear end of the installation frame is provided with symmetrically distributed guide rods located inside the spring, the support plate is embedded with symmetrically distributed sliding sleeves, and one end of the guide rod is slidably inserted inside the sliding sleeve. The conveying rollers provide rolling support for the passing assembly structure to reduce the resistance of the assembly parts, and the spring is positioned by the guide rod when it is extended and retracted, and the guide rod slides inside the support plate through the sliding sleeve to prevent the spring from deflecting.

[0008] Preferably, symmetrically distributed balls are rotatably mounted inside the lower end of the installation frame. When the installation frame moves on the upper end of the bottom plate, the balls roll on the upper end of the bottom plate to provide rolling support for the installation frame.

[0009] Preferably, the bottom of the base plate is provided with symmetrically distributed brackets, and mounting grooves are provided inside the brackets. The brackets support the bottom of the base plate, and the fixings are plugged in through the mounting grooves.

[0010] Preferably, a discharge port is provided inside the upper end of the suction hood, and a sealing plug is provided inside the discharge port. Foreign matter collected inside the suction hood is discharged through the discharge port, and the opening and closing of the discharge port is controlled by the sealing plug.

[0011] Preferably, the suction hood corresponds to the suction hole, and a filter screen is arranged inside the suction hood, which is inclined and the lower part of the inclined surface faces the discharge port. The filter screen intercepts foreign matter sucked into the suction hood by the suction airflow, and guides the airflow to the discharge port through its own inclined surface.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model elastically clamps the main body of the power adapter through a relatively distributed elastically supported installation frame. When clamping, the installation frame is squeezed at the inclined stroke port to achieve squeezing into the installation frames. When the installation frame is elastically clamped, the negative pressure suction force acts on the lower end of the clamped power adapter main body through the bottom plate, and the main body of the power adapter is negatively adsorbed, which is effectively positioned during assembly. After the power adapter is assembled, the material is stored and retrieved by squeezing the assembled workpiece by the subsequent workpiece, which reduces the assembly time and improves the assembly efficiency of the power adapter.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 4 As shown, the utility model proposes a positioning fixture for assembling a power adapter, comprising a support plate 1, a mounting frame 2, a spring 7, a negative pressure pump 11 and a suction hood 13. A symmetrically distributed support plate 1 is arranged on the upper end of the base plate 9, and a symmetrically distributed mounting frame 2 is arranged between the support plates 1. The mounting frames 2 are symmetrically distributed and connected to the support plates 1 at opposite ends. A symmetrically distributed guide rod 4 located inside the spring 7 is arranged at the rear end of the mounting frame 2. A symmetrically distributed sliding sleeve 6 is embedded and installed inside the support plate 1, and one end of the guide rod 4 is slidably inserted into the sliding sleeve 6. Both ends of the mounting frame 2 are inclined outwardly, and a travel port 3 is arranged at the inclined portion of the mounting frame 2. Equidistantly distributed conveying rollers 8 are arranged inside the mounting frame 2. Symmetrically distributed balls 10 are rotatably installed inside the lower end of the mounting frame 2. Symmetrically distributed brackets 5 are arranged at the lower end of the base plate 9, and mounting grooves are opened inside the brackets 5.

[0021] Based on the implementation steps of Example 1: the bottom plate 9 is docked with the base through the bracket 5, and is fixed to the base after the fixing parts are plugged in through the mounting holes. The base is located at the assembly station. When the power adapter is assembled, the main structure squeezes the mounting frame 2 through the travel port 3, and the squeezing force acts on the conveying roller 8 to squeeze the main structure of the power adapter, so that the main structure of the power adapter is labor-saving when being squeezed. The power adapter body located between the mounting frames 2 is elastically clamped by the spring 7, and the clamping force clamps the power adapter body, thereby realizing the positioning of the power adapter during assembly.

[0022] like Figure 1-Figure 4 As shown, compared with the first embodiment, the positioning fixture for assembling a power adapter proposed by the utility model further includes: equally spaced suction holes 17 are opened inside the upper end of the bottom plate 9, a suction hood 13 is arranged at the lower end of the bottom plate 9, a negative pressure pump 11 is arranged at the lower end of the bottom plate 9, a suction pipe 12 is installed through the negative pressure pump 11 and the suction hood 13, a discharge port 14 is opened inside the upper end of the suction hood 13, a sealing plug 15 is arranged inside the discharge port 14, the suction hood 13 corresponds to the suction holes 17, and a filter screen 16 is arranged inside the suction hood 13 in an inclined shape with the lower part of the inclined surface facing the discharge port 14.

[0023] In the present embodiment, before the positioned power adapter main structure is assembled, the suction force of the negative pressure pump 11 acts on the inside of the suction hood 13 through the suction tube 12, and acts on the lower end of the power adapter main structure through the suction hole 17, so as to adsorb and fix the power adapter main body, so that the power adapter main body is stable during assembly. When the power adapter main body is assembled, it is quickly positioned by extrusion, and the assembled power adapter is pushed by the extrusion of subsequent structural parts to push the assembled power adapter out of the clamping of the installation frame 2 for unloading, and at the same time the unassembled power adapter is positioned again.
