Description

Technical Field

[0001] The utility model relates to the technical field of electronic product production, in particular to a pin cutting machine for electronic components. Background Technique

[0002] Electronic components play a crucial role in circuits. They are the basic building blocks in electronic devices and are used to achieve various functions, including but not limited to controlling current flow, storing information, amplifying signals, converting energy, etc. During the production of electronic products, the pins of electronic components pass through the circuit board and are then fixed by soldering. After soldering, a pin cutting machine is required to cut the longer pins on the lower side of the circuit board. The existing cutting machines generally cut the pins through two closed knife bodies. The structure is simple and the use cost is low. However, the knife bodies are generally made of metal and are conductive. Therefore, during the cutting process, the cut pins will be conducted, and there is a risk of short circuit in the electronic components, which will affect the safety of the electronic components. Therefore, special electrically charged pins need to be cut separately, and the processing efficiency is low. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a pin cutting machine for electronic components. Multiple groups of corresponding blades can realize the synchronous cutting of multiple pins, and multiple groups of blades are independent of each other and non-conductive, with high cutting efficiency. At the same time, the use flexibility is good and the convenience is high, which can effectively solve the problems in the background technique.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: A pin cutting machine for electronic components, comprising a frame and a fixing unit;

[0005] Frame: Symmetrically distributed sliding columns are arranged in the middle thereof. Symmetrically distributed insulating support seats are slidably connected between the two sliding columns. Uniformly distributed cutter blocks are installed inside the installation grooves of the insulating support seats close to the longitudinal center of the frame. Blades are arranged at the upper ends of the cutter blocks;

[0006] Fixing unit: It includes an insulating plate and a spring piece. The insulating plates are respectively slidably connected inside the installation holes on the upper surfaces of the insulating support seats. The clamping grooves on the upper surfaces of the lower ends of the cutter blocks are all movably clamped with the vertically corresponding insulating plates. Symmetrically distributed spring pieces are arranged on the upper surfaces of the insulating support seats. The spring pieces are all cooperatively arranged with the vertically corresponding insulating plates. During the use process, multiple groups of corresponding blades can realize the synchronous cutting of multiple pins, and multiple groups of blades are independent of each other and non-conductive, which can ensure that short circuits will not occur between the pins of the electronic components, thereby avoiding damage to the electronic components. And the cutting efficiency is high. At the same time, the use flexibility is good and the convenience is high.

[0007] Further, the fixing unit further includes a control component, which includes a rotating shaft, a circular shaft and a handle. The rotating shafts are respectively rotatably connected to the upper ends of the insulating support seats. Circular shafts are provided at the edges of the rotating shafts close to one end of the insulating plates. The circular shafts are all slidably connected to the vertically corresponding insulating plates. Handles are provided at the ends of the rotating shafts away from the circular shafts, which is convenient for controlling the movement of the insulating plates.

[0008] Further, insulating sheets are provided on both the left and right side surfaces of the cutter block to prevent the cutter blocks corresponding horizontally from coming into contact.

[0009] Further, magnets are provided inside the insulating support seats close to the cutter blocks. Insulating layers are provided on the sides of the magnets close to the cutter blocks. The cutter blocks are magnetically adsorbed to the longitudinally adjacent magnets, ensuring that the cutter blocks are in contact with the insulating support seats and having a good positioning effect on the cutter blocks.

[0010] Further, scales are provided on the side surfaces of the insulating support seats close to the cutter blocks, which is convenient for determining the positions of the cutter blocks.

[0011] Further, support shafts are rotatably connected to both the left and right ends inside the frame. Torsion bars are provided on the outer arc surfaces of the support shafts. The shaft bodies at both ends of the insulating support seats are slidably connected to the vertically corresponding torsion bars, which is convenient for controlling the synchronous movement of the insulating support seats on the front and rear sides in opposite directions.

[0012] Further, an electric push rod is provided at the front end of the frame. The telescopic end of the electric push rod is fixedly connected to the insulating support seat on the front side. The input end of the electric push rod is electrically connected to the output end of an external controller, which is convenient for controlling the movement of the insulating support seat.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: The pin cutting machine for this electronic component has the following advantages:

[0014] 1. The external controller controls the electric push rod to work. The telescopic end of the electric push rod drives the insulating support seat on the front side to slide backward along the sliding column. The shaft bodies at both ends of the insulating support seat drive the torsion bars and support shafts on both sides to rotate clockwise. The torsion bars drive the insulating support seat on the rear side to slide forward along the sliding column. The insulating support seats on both sides drive the blades on the front and rear sides to close through the cutter blocks to cut off the pins of the electronic component. During the use process, multiple groups of corresponding blades can synchronously cut off multiple pins, and multiple groups of blades are independent and non-conductive, which can ensure that there will be no short circuit between the pins of the electronic component, thereby avoiding damage to the electronic component, and the cutting efficiency is high.

[0015] 2. During use, the position of the blade can be adjusted according to the position of the electronic pin. When adjusting, the handle is pulled to drive the rotation of the rotating shaft and the circular shaft. The axis of the circular shaft does not coincide with the axis of the rotating shaft. As a result, the circular shaft slides relative to the long sliding hole at the upper end of the insulating plate, driving the insulating plate to move upward and squeeze the spring piece while separating from the tool block. Then, the tool block moves along the installation groove of the insulating support base. At the same time, the scale can be observed to determine the position of the tool block, and thus the position of the blade can be adjusted. After the adjustment is completed, the handle is released, and the spring piece drives the insulating plate to move downward to press and fix the tool block. The position of the blade can be quickly adjusted according to the usage requirements, with good flexibility and high convenience. Brief Description of the Drawings
