Description

Technical Field

[0001] The utility model relates to a digital tube pin shearing machine. Background Art

[0002] Digital tubes are composed of multiple light-emitting diodes packaged together, and the pins of the light-emitting diodes are set in double rows. Because digital tubes are suitable for printed circuit boards of various thicknesses, digital tube manufacturers often leave the pins of digital tubes very long. However, according to standard requirements: after the pins of the digital tubes are inserted, they should be exposed 1.5mm±0.8mm from the printed circuit board, and the optimal height is 0.8mm~1.2mm. If the pins of the digital tubes are too short, the solder joint strength will be low, and if the pins of the digital tubes are too high, it is easy to cause the solder joints to expose copper. Therefore, before soldering and installing digital tubes on printed circuit boards, it is essential to cut the pins of the digital tubes. Moreover, the cutting requirements for the pins of the digital tubes of the same product should be consistent, and the ports of the pins should be kept flat.

[0003] Some existing pin cutting devices have complex structures, and when cutting double-row pins of digital tubes, the cutting efficiency is low, and the consistency of the pin height after cutting cannot be guaranteed.

[0004] Therefore, it is necessary to develop a digital tube pin cutting machine which has a simple structure and can quickly cut the double-row pins of the digital tube. Utility Model Content

[0005] The utility model aims to provide a digital tube pin cutting machine.

[0006] The utility model provides a digital tube pin cutting machine, comprising:

[0007] Drive device;

[0008] A cutter, wherein a driving device drives the cutter to reciprocate; and

[0009] A carrier plate is provided with a slot for accommodating the pins of the digital tube. The cutter is located below the carrier plate, and the blade of the cutter is attached to the bottom surface of the carrier plate.

[0010] The digital tube pin cutting machine of the utility model inserts the pins of the digital tube into the slots on the carrier board, and the pins of the digital tube extend from the bottom surface of the carrier board. Under the driving action of the driving device, the cutter can cut off the pins extending from the bottom surface of the carrier board. Since the blade of the cutter is attached to the bottom surface of the carrier board, it can ensure that the ports of the pins remain flat after cutting. The thickness of the carrier board, that is, the depth of the slots on the carrier board, needs to be set and determined in advance according to the cutting requirements of the length of the digital tube pins. The digital tube pin cutting machine of the utility model has a simple structure, saves time and effort in cutting the digital tube pins, and can ensure that the ports of the digital tube pins remain flat after cutting. The reciprocating cutter can quickly cut the pins of the digital tube, and can improve the cutting efficiency of the digital tube pins.

[0011] Preferably, it also includes a machine body, two guide rails are provided on the inner wall of the machine body, and slide grooves are provided on the guide rails. The cutter is provided with convex edges on both sides, and the convex edges on both sides of the cutter are respectively accommodated in two slide grooves on the two guide rails. The driving device can drive the cutter to reciprocate along the two guide rails, and the two sides of the supporting plate are respectively arranged on the top of the two guide rails.

[0012] Therefore, the two guide rails ensure that the blade of the cutter can move smoothly on the bottom surface of the carrier plate, ensure the flatness of the port of the digital tube pin after cutting, and ensure the consistency of the pin height after cutting.

[0013] Preferably, it also includes a foot switch, which is connected to the driving device. The foot switch can control the driving device to work or stop working, and the driving device is arranged at the end of the machine body.

[0014] Therefore, the operator can complete the cutting of the digital tube pins by stepping on the foot switch once, which is very convenient.

[0015] Preferably, the driving device is a cylinder, and the cutter is fixed on a piston rod of the cylinder.

[0016] Therefore, the cylinder can smoothly drive the cutter to move on the bottom surface of the carrier plate to complete the cutting of the digital tube pins.

[0017] Preferably, a storage drawer is further included, a gap is left between the bottom of the guide rail and the inner bottom of the body, and the storage drawer is inserted into the body and is located between the bottom of the guide rail and the inner bottom of the body.

[0018] Therefore, the pins cut off by the cutter can fall into the storage drawer, and the storage drawer can be pulled out at regular intervals to dump the cut pins, and the storage drawer can centrally store the cut pins.

[0019] Preferably, a dust cover is further included, which is covered on the machine body and located between the bearing plate and the driving device.

[0020] Therefore, the dust cover can prevent foreign matter from falling into the machine body and affecting the normal sliding of the cutter and the normal operation of the driving device.

[0021] Preferably, a fixing plate is provided on the side of the machine body, and the driving device is arranged on the fixing plate.

[0022] Therefore, the driving device and the machine body can be formed into a whole through the fixing plate, which is convenient for overall movement.

[0023] Preferably, the slot includes a first slot and a second slot arranged in parallel.

[0024] Therefore, the double-row pins of the digital tube can be respectively inserted into the first slot and the second slot, and the cutter can cut off the pins extending from the bottom surface of the carrier board.

[0025] Preferably, a first plugging hole is provided at one end of the first slot, a second plugging hole is provided at one end of the second slot, the first plugging hole is close to one side of the carrier board, and the second plugging hole is close to the other side of the carrier board.

[0026] Therefore, some products have special requirements for the installation position and angle of the digital tube, and the length of one row of pins in the double-row pins on the digital tube is required to gradually decrease, that is, the row of pins is distributed obliquely as a whole. For such a digital tube, the four corners of its shell have support feet respectively, and the length of one of the support feet is greater than the lengths of the other three support feet. When cutting the pins of such a digital tube, just set the thickness of the carrier board, insert the longer support foot on the digital tube shell into the first plug-in hole of the first slot or the second plug-in hole of the second slot, and insert the double-row pins of the digital tube into the first slot and the second slot respectively, so that the digital tube is inserted into the carrier board in an oblique shape as a whole, and then under the driving action of the driving device, the cutter cuts off the pins extending from the bottom surface of the carrier board. In this way, the length of one row of pins of the cut digital tube is gradually reduced, and the row of pins is distributed obliquely as a whole, thereby meeting the installation requirements of the digital tube on the product.

[0027] Preferably, the slot further includes a third slot, which is arranged in parallel with the first slot and the second slot, and a third plugging hole is provided at one end of the third slot, and the third plugging hole is close to the other side of the carrier board.

[0028] Therefore, according to the distance size of the double-row pins of the digital tube, you can choose to plug the double-row pins of the digital tube into the first slot and the second slot, or you can choose to plug the double-row pins of the digital tube into the first slot and the third slot, or you can choose to plug the double-row pins of the digital tube into the second slot and the third slot, so that it can be suitable for the pin cutting of various models of digital tubes.
