Description

Technical Field

[0001] This invention relates to the field of lead cutting technology, specifically to a lead cutting and forming device for electronic components. Background Technology

[0002] Electronic components are a general term for electronic devices such as capacitors, transistors, hairsprings, and clockwork. The pins of electronic components are the wires that extend from the internal circuitry of the component to connect to external circuits; all the pins constitute the interface of the electronic component. To ensure stable electrical conduction between the electronic component and the PCB board, the pins of electronic components are generally designed to be relatively long to accommodate PCBs of varying thicknesses. Therefore, electronic components often need to have their pins trimmed before soldering.

[0003] like Figure 1 The electronic component 1 shown has pins 2 distributed on both sides of it. The pins 2 extend downwards. Since the angle between the pins 2 and the electronic component 1 is not fixed and is generally between 0 and 90°, during cutting, it is necessary to ensure that the cutting blade cuts vertically on the pins 2. On the other hand, it is also necessary for the two cutting blades on the same side to cut the pins 2 simultaneously and synchronously. Otherwise, the shearing force may be unevenly distributed at the cut surface, resulting in uneven stress near the cut surface and bending. Bending at the cut surfaces of multiple pins 2 will cause the solder joints to be on different planes, directly affecting the soldering quality of the electronic component.

[0004] Furthermore, since the pins 2 of electronic component 1 are distributed on both sides of electronic component 1, if the pins 2 on both sides are cut sequentially, during the cutting process, the pins on the first side will be subjected to force while the pins on the other side will not be subjected to force. Moreover, since electronic component 1 is small in size and weight, it is easy to cause displacement of electronic component 1. When cutting the pins 2 on the other side, it is necessary to reset the position of electronic component 1.

[0005] Therefore, an electronic component pin cutting and forming device is proposed to address the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an electronic component pin cutting and forming device to solve the problems mentioned in the background art, namely, "when facing electronic components with pins distributed on both sides, it is necessary to ensure that the cutting blade cuts vertically on the pins, and on the other hand, it is necessary for the upper and lower cutting blades on the same side to cut the pins simultaneously and synchronously, and the electronic components are easily displaced when cutting from both sides in sequence."

[0007] To achieve the above object, the present application provides the following technical solutions: An electronic component pin shearing and forming device comprises two bottom plates on the left and right sides, the top end of the bottom plate is fixedly connected with a support rod, the top end of the support rod is rotatably connected with a front rotating disc, the bottom end of the front rotating disc is fixedly connected with a U-shaped rod, the other top end of the U-shaped rod is fixedly connected with a rear rotating disc, the axis lines of the front rotating disc and the rear rotating disc are on the same straight line, one side of the front rotating disc and the rear rotating disc is fixedly connected with a fourth cylinder, the movable end of the fourth cylinder is fixedly connected with a connecting disc, the connecting disc is slidably connected with an upper cutter and a lower cutter, and the upper cutter and the lower cutter are used to cut the pin.

[0008] The front rotating disc and the rear rotating disc on the front and rear sides can synchronously rotate in the same direction, the front rotating discs on the left and right sides can synchronously rotate in opposite directions, the inner side of the front rotating disc is fixedly connected with a first laser emitter and a second laser emitter, the inner side of the rear rotating disc is fixedly connected with a first laser receiver and a second laser receiver, the position of the first laser emitter in the front rotating disc corresponds to the position of the first laser receiver in the rear rotating disc, and the position of the second laser emitter in the front rotating disc corresponds to the position of the second laser receiver in the rear rotating disc.

[0009] As the electronic component pin shearing and forming device, preferably, the first laser emitter and the first laser receiver are respectively located at the center of the front rotating disc and the rear rotating disc, the upper cutter and the lower cutter are symmetrically arranged on the plane where the first laser emitter and the second laser emitter are located, and the upper cutter and the lower cutter are perpendicular to the plane where the first laser emitter and the second laser emitter are located.

[0010] Under the above arrangement, when in use, the device can not only cut multiple pins at the same time, adjust the length of the cut, and increase the cutting efficiency, but also ensure the vertical cutting of the upper cutter and the lower cutter on the pins at different angles, and can cut the pins with the upper cutter and the lower cutter at the same time, which can effectively avoid the uneven distribution of the shearing force on the pin cutting surface, thereby avoiding the bending phenomenon caused by the uneven stress near the cutting surface, and reducing or even avoiding the problem that the bending of the multiple pin cutting surfaces makes the welding points not on the same plane, directly affecting the welding quality of the electronic component.

[0011] When the device works, the electronic component is first placed in the center of the placing plate, and then the height of the electronic component is adjusted by the lifting of the second cylinder, and when the pin near the end of the electronic component is between the first laser emitter and the first laser receiver, i.e., when the first laser receiver cannot receive the light emitted by the first laser emitter, the height adjustment of the electronic component is stopped.

[0012] The angle of the front rotating disc is changed, at this time, because the first laser emitter is at the center of the circle, with the upward rotation of the front rotating disc, the positions of the first laser emitter and the first laser receiver remain unchanged until the pin is between the second laser emitter and the second laser receiver again, that is, the second laser receiver cannot receive the second laser emitter, the rotation of the front rotating disc is stopped, at this time, the pin is on the plane where the first laser emitter and the second laser emitter are located, and the upper cutter and the lower cutter are perpendicular to the pin;

[0013] According to the length to be cut, the fourth cylinder is controlled to work, so that the fourth cylinder is contracted, and after being contracted to the required distance, the upper cutter and the lower cutter work simultaneously to realize the vertical cutting of the pin.

[0014] Preferably, the forming device further comprises a third cylinder, the movable end of the third cylinder is fixedly connected with a top plate, the top end of the top plate is fixedly connected with a limiting rod, the two sides of the limiting rod are slidably connected with lifting plates, the sliding connection of the limiting rod and the lifting plates is used for distance compensation, the two lifting plates are respectively arranged on the lower sides of the left and right U-shaped rods, the outer sides of the U-shaped rods are rotatably connected with sleeves, the bottom end of each sleeve is fixedly connected with a connecting rod, and the bottom end of each connecting rod is rotatably connected with the top end of the lifting plate, so that the U-shaped rods are upwardly rotated through the upward movement of the lifting plate.

[0015] Preferably, the bottom end of each connecting rod is inclined to the direction of the connecting disc on the same side, so that the front rotating discs on the two sides are oppositely rotated.

[0016] Preferably, the bottom end of each lifting plate is fixedly connected with a telescopic rod, the bottom end of the telescopic rod is fixedly connected with the bottom end of the bottom plate, and the telescopic rod is used for limiting the lifting plate, so that the left and right deviations of the lifting plate are prevented.

[0017] The electronic component can also be simultaneously cut on both sides, avoiding the problem that when cutting in sequence, the first side of the pin is stressed, the other side of the pin is not stressed, the electronic component is displaced, and the position of the electronic component needs to be reset when cutting the other side of the pin;

[0018] Because the left and right cutting mechanisms are arranged, the front rotating discs on the two sides can be oppositely rotated during the rotation of the front rotating disc, so that the pins on the two sides are simultaneously perpendicular to the upper cutters and the lower cutters on the two sides, the two sides are simultaneously cut, the stress unevenness of the electronic component during single-side pin cutting is compensated and offset, the resetting operation problem is reduced, and the efficiency is improved.

[0019] When the movable end of the third cylinder rises, the top plate also rises, and the top plate drives the lifting plate to move upward through the limiting rod; when the lifting plate moves upward, the lifting plate drives the front rotating disc to rotate through the connecting rod; because the bottom end of each connecting rod is inclined to the direction of the connecting disc on the same side, and there is an angle difference between the connecting rod and the U-shaped rod, the rotating direction of the U-shaped rod can be controlled by using the angle difference, so that the front rotating discs on both sides rotate in opposite directions, thereby making the connecting discs on both sides rotate downward synchronously, and the cutting angles on both sides are adjusted at the same time.

[0020] Preferably, the forming device further comprises a second cylinder, and a placing plate is fixedly connected to the top movable end of the second cylinder; the upper surface of the placing plate is used for placing the electronic component; and the pin of the electronic component is located between the front rotating disc and the rear rotating disc.

[0021] Preferably, the forming device further comprises a fixed plate, one end of the fixed plate is fixedly connected with a first cylinder, and the movable end of the first cylinder is fixedly connected with one side of the bottom plate.

[0022] Under the above arrangement, the first cylinder can drive the bottom plate to move left and right, so as to realize cutting of electronic components of different widths.

[0023] Preferably, the bottom end of the bottom plate is rotationally connected with a rotating wheel used for supporting and moving.

[0024] Preferably, two symmetrical sliding grooves are formed in the connecting disc, the inner side of each sliding groove is slidably connected with a sliding block, the upper sliding block is fixedly connected with the upper cutter, the lower sliding block is fixedly connected with the lower cutter, and the cutting action of the upper cutter and the lower cutter is realized through the opposite movement of the two sliding blocks.

[0026] Under the above arrangement, the cutting mode of the upper cutter and the lower cutter in the present application is as follows: the motor drives the screw rod to rotate, because the screw threads on the two sides of the screw rod are opposite in direction, the rotation of the screw rod drives the sliding blocks in the two sliding grooves to move towards or away from each other, and the sliding blocks drive the upper cutter and the lower cutter to move towards or away from each other; when the upper cutter and the lower cutter move towards each other, the pin can be cut.

[0027] Compared with the prior art, the present application has the following beneficial effects:

[0028] 1. The electronic component pin shearing and forming device can simultaneously cut multiple pins, adjust the length of the cut, increase the cutting efficiency, ensure the vertical cutting of the upper and lower cutters on pins at different angles, simultaneously cut the pins with the upper and lower cutters, effectively avoid uneven distribution of cutting force on the pin cutting surface, thereby preventing bending of the pin cutting surface, and directly affecting the welding quality of the electronic component.

[0029] 2. The electronic component pin shearing and forming device can place the electronic component in the center of the placement plate, adjust the height of the electronic component through the second cylinder, stop the height adjustment when the pin near the end of the electronic component is between the first laser emitter and the first laser receiver, start changing the angle of the front rotating disc, keep the position of the first laser emitter and the first laser receiver unchanged with the upward rotation of the front rotating disc until the pin is between the second laser emitter and the second laser receiver, stop the rotation of the front rotating disc, cut the pin vertically with the upper and lower cutters according to the required length, control the fourth cylinder to work, and cut the pin vertically with the upper and lower cutters.

[0030] 3. The electronic component pin shearing and forming device can simultaneously cut the pins on both sides of the electronic component, avoid the displacement of the electronic component caused by the uneven force on the pins when cutting one side first, and reset the position of the electronic component before cutting the other side, because the device is equipped with two cutting mechanisms on the left and right sides, the opposite rotation of the front rotating discs on both sides can be realized during the rotation of the front rotating discs, the pins on both sides can be vertically cut with the upper and lower cutters on both sides at the same time, the uneven force on the electronic component during single side pin cutting can be compensated and offset, the resetting operation can be reduced, and the efficiency can be improved.

[0031] 4、The third cylinder of the electronic component pin shearing and forming device rises, the top plate also rises, the top plate drives the lifting plate to move upward through the limiting rod, the lifting plate drives the front rotating disc to rotate through the connecting rod when the lifting plate moves upward, because the bottom end of the connecting rod on each side is inclined to the direction of the connecting disc on the same side, there is an angle difference between the connecting rod and the U-shaped rod, the rotating direction of the U-shaped rod can be controlled by using the angle difference, so that the front rotating discs on both sides rotate in opposite directions to make the connecting discs on both sides rotate downward synchronously, and the cutting angles on both sides are adjusted at the same time.

[0049] When the present application works, the electronic component 1 is first placed in the center on the placing plate 18, and then the height of the electronic component 1 is adjusted through the lifting of the second cylinder 6, when the pin 2 near the end of the electronic component 1 is between the first laser transmitter 25 and the first laser receiver 19, i.e., the first laser receiver 19 cannot receive the light emitted by the first laser transmitter 25, the height adjustment of the electronic component 1 is stopped.

[0050] The angle of the front rotating disc 16 is started to be changed, at this time, because the first laser transmitter 25 is located at the center, with the upward rotation of the front rotating disc 16, the positions of the first laser transmitter 25 and the first laser receiver 19 remain unchanged, until the pin 2 is again between the second laser transmitter 26 and the second laser receiver 20, i.e., the second laser receiver 20 cannot receive the second laser transmitter 26, the rotation of the front rotating disc 16 is stopped, at this time, the pin 2 is on the plane where the first laser transmitter 25 and the second laser transmitter 26 are located, and the upper cutter 22 and the lower cutter 23 are also perpendicular to the pin 2.
