Description

Technical Field

[0001] The utility model belongs to the technical field of capacitor production equipment, in particular to a lead wire cutting device used in capacitor production. Background Art

[0002] Capacitors are electronic components used to store electrical energy. Capacitors not only include the capacitor body, but also the leads welded thereon. These leads are used to weld the capacitor to electronic components such as circuit boards. The leads mentioned above are required for capacitor production, so they are longer and easier to weld to the capacitor. After welding, the leads of the capacitor need to be cut.

[0003] A Chinese patent application (or patent) with the announcement number CN220372103U discloses a lead cutting device for capacitor production, including a capacitor feed box: the left side of the bottom of the inner cavity of the capacitor feed box is fixedly connected with a left fixed baffle, the right side of the bottom of the inner cavity of the capacitor feed box is fixedly connected with a right fixed baffle, and the inner cavity of the capacitor feed box is rotatably connected with a capacitor dividing block through a rotating shaft. The utility model drives the rotating shaft to rotate intermittently through the rotation of the rotating disk, thereby driving the capacitor dividing block to rotate intermittently in the inner cavity of the capacitor feed box. When the capacitor dividing block rotates to drive the capacitor in the inner cavity of the capacitor accommodating cavity to the position of the circular push plate, the capacitor is pushed to slide forward in the inner cavity of the capacitor accommodating cavity through the sliding of the circular push plate. As the capacitor dividing block rotates, the cutting device cuts the protruding leads, thereby achieving the purpose of automatically cutting the leads and improving the production efficiency of capacitors.

[0004] The above-mentioned lead cutting device for capacitor production is provided with a capacitor feeding box for feeding capacitor storage boxes, and the inner chamber of the capacitor feeding box is much larger than the capacitor, so that more capacitors can be stored. However, the lead lengths on the capacitors are different, and using capacitor storage boxes of the same thickness to store them will cause the capacitors to shake in the storage box, and then the capacitors stored in the capacitor dividing block have different degrees of fit between the rear side walls and the inner wall of the dividing block, which will cause the lengths of the leads remaining on the capacitors after cutting to be different; and, a device for driving The motor and gears that rotate the capacitor dividing block are used to drive the capacitor dividing block to contact the cutting device with the leads on the capacitor during cutting, thereby achieving the effect of cutting the leads. However, the leads on the capacitor are relatively soft, and because the solder joints are very small, when the leads contact the cutting device, in order to ensure that the leads can be accurately cut, the capacitor dividing block needs to rotate at an extremely fast speed to contact the capacitor with the cutting device. However, the faster rotation speed of the capacitor dividing block will cause the cut capacitors stored in the tooth grooves to be difficult to fall off for unloading. To this end, we provide a lead cutting device for capacitor production to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a lead wire cutting device for capacitor production. By utilizing a slide-shaped material feeding trough on a cutting box, the capacitors put into the cutting box can be automatically arranged, and the redundant lead wires pass through the lead wire groove on the glass cover plate, which not only makes the length of the lead wires left after cutting uniform, but also can automatically carry out orderly material feeding after cutting is completed, thereby solving the problems of the lead wire cutting device for capacitor production mentioned above.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a lead wire cutting device for capacitor production, comprising a cutting box; a material feeding trough is provided inside the cutting box, and a material inlet is provided on the head of the material feeding trough and the top side wall of the cutting box, a material outlet is provided on the tail of the material feeding trough and the right side wall of the cutting box, and a material guide plate is installed on the outer side of the material outlet, a sealing component is provided on the front side wall of the cutting box, the sealing component comprises a plate frame inlaid on the front outer wall of the cutting box, a card frame is fixedly installed on the front side wall of the plate frame, and a glass cover plate is arranged inside the card frame, a lead wire groove is also provided on the glass cover plate, a material feeding hopper is fixedly installed on the bottom front side wall of the cutting box, a cutting component is also arranged on the outer side of the glass cover plate and inside the card frame, a pneumatic rod in the cutting component is fixedly installed on the bottom side wall of the card frame, a knife holder is installed on the shaft end of the pneumatic rod, and a cutting knife is installed on the knife holder.

[0008] The utility model is further configured such that the material trough and the wire guide trough have the same structure, and the paths of the material trough and the wire guide trough are the same, and the material trough and the wire guide trough are both arranged alternately downward in a slide-like structure.

[0009] The utility model is further configured that an inlay groove is provided on the front side wall of the cutting box, the cutting box is clamped with the plate frame through the inlay groove, and a clamping groove is provided inside the plate frame.

[0010] The utility model is further configured that a cutting strip is fixedly mounted on the rear side wall of the card frame, the card slot is connected to the outer wall of the card frame through the cutting strip, and a sliding groove is provided on the inner wall of the card frame.

[0011] The utility model is further configured such that two ends of the tool holder in the cutting assembly extend into the slide groove, and the two side shaft ends of the tool holder slide in cooperation with the inner wall of the slide groove, and the cutting knife on the tool holder fits with the outer wall of the glass cover plate.

[0012] The utility model is further configured that a connecting sleeve is fixedly installed on the bottom side wall of the tool holder, and the tool holder is threadedly connected to the telescopic end of the pneumatic rod through the connecting sleeve, and a fixing sleeve is fixedly installed on the bottom of the pneumatic rod.

[0013] The utility model is further configured that a mounting hole is opened on the bottom side wall of the slide slot, and there are three mounting holes in total, the three mounting holes are arranged at equal intervals, and the mounting holes and the pneumatic rods are arranged in a one-to-one correspondence.

[0014] The utility model is further configured that the outer side of the mounting hole and the bottom outer wall of the clamping frame are fixedly connected to the fixing sleeve, and the clamping frame is connected to the pneumatic rod through the fixing sleeve.

[0015] The utility model has the following beneficial effects:

[0016] The utility model provides a cutting box, wherein a material feeding groove in the shape of a slide is provided inside the cutting box, and a sealing component is also provided on the front side of the cutting box. By utilizing a glass cover plate in the sealing component, the state of the capacitor put into the cutting box and naturally sliding down along the material feeding groove can be observed, and the lead wires on the capacitor are placed in the lead wire grooves on the glass plate and pass through the lead wire grooves. The groove width of the lead wire grooves is smaller than the material feeding grooves, so the capacitors in the material feeding grooves will not flow out of the lead wire grooves and leave the cutting box. When cutting, only the lead wires on the capacitors outside the lead wire grooves need to be uniformly cut off, and the lengths of the lead wires left after cutting are also the same.

[0017] The utility model provides a cutting assembly and a collecting hopper, and the cut leads can be recovered by utilizing the collecting hopper, so as to be convenient for subsequent use. The pneumatic rod in the cutting assembly can be used to push the cutting knife thereon to move up and down on the outer side of the glass cover plate, so as to realize cutting of the leads on the capacitor passing through the lead groove on the glass cover plate. Because the material trough in the cutting box is in the shape of a slide, and after the cutting is completed, as long as the baffle at one end of the discharge port is opened, the capacitor with the excess pins cut off in the cutting box will naturally flow out through the guide plate due to the dead weight of the capacitor.
