Description

Technical Field

[0001] The utility model relates to the technical field of terminal cutting, in particular to a terminal cutting device. Background Art

[0002] Electronic components, especially various connectors, usually include many metal PIN pins (also called terminals). The above PIN pins are fixed on a plastic base by injection molding or pressing to form a connector. When the PIN pins leave the factory, they are usually fixed on a tape. On a long metal tape, many PIN pins are arranged to form a very long tape roll. Therefore, before processing the connector, the tape roll is usually cut into sections according to the number of PIN pins, and each section has the same number of PIN pins. In this way, it can be assembled or injection molded with the plastic base.

[0003] In the Chinese utility model patent with the publication number of CN220585691U, a terminal cutting device is disclosed. By setting a feeding tape and a discharging tape, the terminal cutting device is provided with a cleaning mechanism. The brush can swing in an arc as the limiting plate moves up and down, and during the swinging process, it can clean the feeding tape and the discharging tape, and sweep the waste residues, dust, etc. generated during the cutting process into the recycling box. This not only makes it more environmentally friendly, but also can timely remove the waste residues on the terminal tape, avoiding damage to the terminal tape caused by the adhesion of waste residues, dust, etc., affecting subsequent use, greatly improving the environmental protection benefit and economic benefit of the cutting device, reducing the potential danger coefficient, reducing the workload of maintenance and inspection of the staff, and improving the versatility of the device.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects: when the device cuts the terminals, it abuts against the terminals in the vertical direction, but when cutting the terminals, the terminals may shift, which will affect the discharging effect of the terminals. It is necessary to abut against the side of the terminals to reduce the situation of terminal shift. Summary of the Utility Model

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. The utility model reduces the up-and-down jitter of the terminal strip during transportation by setting a limit transportation component. When the motor is started, the motor drives the conveying wheel to rotate, so that the terminal strip is conveyed to the right. During the transportation process, the pressure roller abuts against the surface of the terminal strip. At the same time, according to the width of the terminal strip, the lead screw is rotated, so that the threaded cylinder drives the abutting plate to abut against the side of the terminal strip, reducing the deviation of the terminal strip during movement. When the device cuts the terminal strip, the terminal strip remains parallel to the strip, improving the discharging effect of the device.

[0017] 2. When cutting the terminal strip, the utility model starts the cylinder by setting a cleaning and cutting component. The cylinder drives the cutter to move downward through the moving plate to cut the terminal strip. During this process, the moving plate drives the connecting seat to move downward, so that the connecting rod pushes the toothed plate to move to the left through the fixed seat, causing the gear to drive the threaded rod to rotate, thereby driving the pushing cylinder to drive the brush plate to move forward through the sliding plate. At the same time, under the action of the air suction box and the connecting pipe, the brush plate brushes and absorbs the dust on the surface of the terminal strip. During the reset process of the cutter, the sliding plate drives the brush plate to clean the terminal strip again, avoiding the influence of dust and impurities on the discharging of the terminal strip and improving the discharging effect of the terminal strip.
