Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and in particular to a device for shaping plug pins. Background Technology

[0002] A power plug is a device that connects electrical appliances and other devices to a power source. Power plugs are generally classified as 2-pin, 3-pin, and multi-pin plugs. A 2-pin plug has two prongs or two pins; similarly, a 3-pin plug has three prongs or three pins. Multi-pin plugs are more complex, requiring the number of prongs or pins to be selected based on the specific needs of the device, and their arrangement also needs careful consideration.

[0003] Currently, the prongs of most 3-pin power plugs on the market are arranged in a triangular pattern. However, these three prongs are prone to deformation during the manufacturing process, either concave inward or convex outward. In such cases, the 3-pin power plug does not meet the production requirements and needs subsequent prong reshaping and correction. Most current prong reshaping devices for 3-pin power plugs can only correct prongs that are either concave or convex. This necessitates classifying the deformation of the prongs before placing them into the appropriate reshaping devices. If the plug has both concave and convex prongs, two correction processes are required, reducing efficiency. Therefore, it is necessary to improve existing prong reshaping devices. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a shaping device for plug pins, which can effectively solve the problem of low correction efficiency of the plug pins when they are deformed in existing power plugs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A plug pin shaping device includes a machine platform, a conveying mechanism, a pin expansion mechanism, and a pin retraction mechanism. The machine platform is provided with a feeding track, and a slot for the plug pins to pass through is opened below the feeding track. The feeding track has a shaping area. The conveying mechanism is disposed on the machine platform. The pin expansion mechanism is movably disposed on the machine platform and located below the shaping area. The pin expansion mechanism is close to the input end of the feeding track and has an expansion member that can move up and down and open and close to promote pin expansion. The pin retraction mechanism is movably disposed on the machine platform and located below the shaping area. The pin retraction mechanism is close to the output end of the feeding track and has a retraction member that can move up and down and open and close to promote pin retraction.

[0007] As a preferred embodiment, the conveying mechanism includes a lead screw drive module, a slider, a first cylinder drive module, and a material picking component. The lead screw drive module is mounted on the machine platform and located above the forming area. The lead screw drive module has a lead screw. The slider is movably mounted on the lead screw drive module and is connected to the lead screw, which drives it to move back and forth.

The first mounting ring has multiple first hinge positions. One end of each of the multiple first hinge arms is hinged to a corresponding first hinge position. Each of the multiple first shaping parts is hinged to the other end of a corresponding first hinge arm. Each first shaping part is provided with a first guide part, and each first guide part can be movably assembled in a corresponding first guide groove. When the second push rod pushes upward, each first guide part moves outward within the first guide groove, causing the multiple first shaping parts to move outward.

[0011] As a preferred embodiment, the pin expansion mechanism includes a second ejection module, a third cylinder drive module, and a retraction component. The second ejection module is mounted on the machine base, and the third cylinder drive module is mounted on the second ejection module and is ejected upwards or retracted downwards by the second ejection module.

[0012] As a preferred embodiment, both the input and output ends of the feeding track are equipped with laser sensors for detecting whether the plug is in place.

[0013] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0014] By movably arranging the pin expansion mechanism and pin retraction mechanism below the shaping area, when the plug enters the shaping area of ​​the feeding track and is located above the pin expansion mechanism, the pin expansion mechanism moves upward, and the expansion member enters between the three pins of the plug. Then, the expansion member opens, spreading the three pins apart. Next, the conveying mechanism transports the plug above the pin retraction mechanism, and the pin retraction mechanism moves upward, with the retraction member surrounding the three pins of the plug. Subsequently, the retraction member closes, retracting and resetting the three pins of the plug. This allows a single device to correct and reset different deformation conditions of the pins, significantly improving the pin correction efficiency.
