Description

Technical Field

[0001] This application relates to an automatic shearing and bending device for Hall elements. Background Technology

[0002] Hall effect sensors are widely used in circuit boards. Due to their relatively large size, the leads of the Hall effect sensors need to be bent to fit the flattened structure of circuit boards. Currently, stamping is generally used to bend the leads. Because the leads of Hall effect sensors are small, even a small offset during the stamping process can damage them. This slight offset mainly comes from two aspects: the consistency of the Hall effect sensor's feed position and the consistency of the stamping position, especially whether the stamping position can be kept consistent. Utility Model Content

[0003] To address the aforementioned problems, this application proposes an automatic shearing and bending device for Hall elements, comprising a support frame, a pushing section and a stamping section cooperating with the pushing section, and a guide channel for conveying the Hall element strip, with an operating groove exposing the Hall element strip on one side of the guide channel corresponding to the pushing section. This application uses a guide channel to guide the Hall element strip before it enters the operating groove for shearing and bending operations. Due to the guiding effect of the guide channel itself, the controllability of the Hall element strip feeding process can be further ensured.

[0004] Preferably, the pushing part includes a pushing piston cylinder, a plurality of pushing piston rods extending out of the pushing piston cylinder, and a positioning pressing plate that cooperates with the Hall element at the end of the pushing piston rod.

[0006] Preferably, an oblique feeding knife is connected to the end of the L-shaped plate via an end hinge shaft, and a return torsion spring is provided on the end hinge shaft. The oblique feeding knife is obliquely positioned in the direction of movement of the Hall element belt, and a feeding wear-resistant block is provided at the position of the oblique feeding knife corresponding to the guide channel.

The guide bolts extend to the outside of the guide channel wall, and a bolt protrusion is provided at the bottom of the guide bolt. A return spring is provided between the bolt protrusion and the guide channel wall. An outer protective plate is provided on the side of the lower pressure plate. This application, through the abutment of the brake and the oblique feed knife, ensures stable unidirectional feeding of the Hall element belt by the return spring driving the guide bolts to press the lower pressure plate and the return torsion spring driving the oblique feed knife to press the Hall element belt.

[0008] Preferably, the stamping part includes a stamping piston cylinder, a stamping piston rod extending out of the stamping piston cylinder, a stamping table at the end of the stamping piston rod, and a guide stamping head at the side of the stamping table.

This application replaces the stamping head body by replacing the stamping frame. When only shearing is required, only the shearing head can be installed. When shearing and bending are required, both the shearing head and the bending head need to be installed, making the function more versatile.

[0012] Preferably, the support frame includes a bottom support plate, on which a plurality of vertical support rods are provided. A receiving area is provided on one side of the vertical support rods corresponding to the side of the stamping part. A top support plate is provided at the top of the vertical support rods. The guide channel is provided on the top support plate. A guide plate is also provided in front of the guide channel, and an arc-shaped plate is also provided on the side of the guide plate away from the guide channel.
