Description

Technical Field

[0001] The present invention relates to the technical field of pin shearing, and particularly to a pin cutting device for electronic components. Background Art

[0002] With the development and progress of printed circuit boards, various electronic devices are assembled into circuits more quickly and conveniently. Especially after the emergence of wave soldering, the perforation welding speed of electronic devices on printed circuit boards has also been greatly improved, effectively promoting the development of the microelectronics industry. However, during the production and manufacturing of electronic devices, it is still necessary to shear the overly long pins on the electronic devices. Currently, during the process of shearing the pins of electronic devices, due to the displacement of the pins during shearing, the shearing position is inaccurate, affecting the shearing quality of the pins of electronic devices. Summary of the Invention

[0003] The purpose of the present invention is to provide a pin cutting device for electronic components. By pressing a part of the pins of the electronic device with a positioning plate to play a positioning role, it can avoid over-cutting or inaccurate cutting positions when shearing the pins of the electronic device. At the same time, it cooperates with a pressing plate to stabilize the electronic device, enabling more accurate shearing of the pins of the electronic device and improving the shearing quality of the pins of the electronic device.

[0004] To achieve the above object, the present invention provides the following technical solution: A pin cutting device for electronic components, including a workbench, as well as a feeding device and a conveying device located on the workbench for automatic feeding and conveying. A shearing mechanism for positioning and shearing the pins of the electronic device, and a bending mechanism for assisting the shearing mechanism to accurately shear the pins of the electronic device are provided on the workbench.

[0005] The shearing mechanism includes a base located on the workbench. An electric slide is arranged on the base and moves up and down. A hydraulic shearing knife that moves synchronously with the electric slide is arranged on one side of the electric slide. A positioning plate that slides on the same horizontal plane as the hydraulic shearing knife is arranged on one side of the hydraulic shearing knife. A shearing table that cooperates with the feeding device for feeding is arranged below the electric slide. The bending mechanism includes a slide that slides on the shearing table. An electric push rod for driving its movement is arranged on one side of the slide. A groove is opened at the bottom of the shearing table. An air storage chamber for containing gas is arranged on the slide. A piston cylinder is communicated with the bottom of the air storage chamber. A piston rod that pushes the gas inside the piston cylinder to move when moving inside the piston cylinder is arranged inside the groove. A through pipe for wrapping the pins of the electronic device is arranged on one side of the air storage chamber. An air bag communicated with the air storage chamber is arranged inside the through pipe. A shearing seat that moves synchronously with the slide is arranged on one side of the slide. A push plate slides inside the shearing seat. A third gear tooth is arranged on one side of the groove. A gear that rotates when the shearing seat moves and meshes with the third gear tooth is arranged on one side of the shearing seat. A power storage shaft is rotatably connected to one side of the gear. After the power storage shaft rotates following the gear to store power, when the gear rotates in the reverse direction and cannot drive the power storage shaft to rotate, the power storage shaft releases power and at the same time drives the push plate to move upward to squeeze the pins and bend them.

[0006] Preferably, an electric slide rail is arranged on the base, and the electric slide slides on the electric slide rail.

[0007] Preferably, a pressing plate for fixing the electronic device is arranged below the electric slide, and a scale rod for the hydraulic shearing knife to slide is arranged on one side of the electric slide.

[0008] Preferably, both the hydraulic shearing knife and the positioning plate are connected through the scale rod. The positioning plate moves following the hydraulic shearing knife, and the positioning plate moves on the hydraulic shearing knife.

[0009] Preferably, the slide slides inside the shearing table. While the slide slides inside the shearing table, the slide drives the piston cylinder to move, and then the piston rod pushes the gas inside the piston cylinder to move. When the gas inside the piston cylinder moves into the air storage chamber and reaches a certain amount, the gas inside the air storage chamber enters the air bag inside and makes the air bag expand to wrap and squeeze the pins of the electronic component.

[0010] Preferably, the third gear tooth is arranged on a part of one side of the groove, and the gear meshes with the third gear tooth.

[0011] Preferably, when the gear rotates by meshing with the third gear tooth, it will drive the power storage shaft to rotate. When the gear rotates in the reverse direction, it will not drive the power storage shaft to rotate. The power storage shaft is rotatably arranged on the shearing seat.

[0012] Preferably, a torsion spring capable of storing energy during rotation is provided on the energy storage shaft.

[0013] Preferably, a first set of teeth is provided on the surface of the energy storage shaft, and the push plate moves inside the shear seat.

[0014] Preferably, a second set of teeth is provided on one side of the push plate, and the first set of teeth is movably connected to the second set of teeth.

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

[0016] 1. By adjusting the distance between the positioning plate and the hydraulic shear blade, after the electric slide drives the pressing plate to move downward to stabilize the electronic device, the positioning plate can press a part of the pins of the electronic device, avoiding over-cutting or inaccurate cutting positions when the hydraulic shear blade cuts the pins of the electronic device; thus, cooperating with the pressing plate to stabilize the electronic device, the pins of the electronic device can be cut more accurately, improving the cutting quality of the pins of the electronic device.

[0017] 2. Before the valve opens when the pressure inside the air storage chamber does not reach a certain value, the excess pins of the electronic device will extend into the inside of the through pipe, and at this time, the airbag is not inflated; after the pressure inside the air storage chamber changes to a certain value, the airbag is inflated and expands to wrap and squeeze the pins of the electronic device. At the same time, cooperating with the electronic device being squeezed and stabilized by the pressing plate, after the airbag is inflated and expands, it can straighten the bent pins to a nearly straight state. Thus, during the process of calculating the length when cutting the pins of the electronic device, it is more accurate, avoiding the bent state of the electronic device from affecting the judgment of the cutting position.

[0018] 3. The present invention uses the slide to drive the shear seat to move in the reverse direction. The shear seat drives the push plate to move out from under the positioning plate. At this time, the torsion spring will start to release energy, and the torsion spring will drive the energy storage shaft to rotate in the reverse direction. Since the first set of teeth is movably connected to the second set of teeth, the energy storage shaft will drive the push plate to move upward. The upward movement of the push plate will squeeze the pins, forcing the pins to bend. Thus, it automatically performs bending processing on them, saving the workload of the staff. At the same time, cooperating with the design of the positioning plate pressing part of the pins, it can ensure that there is a distance between the bent part and the root of the pins, avoiding bending the pins from the root when manually bending the pins, resulting in pin breakage and increased costs.

Specific implementation manners

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] The present invention provides a pin cutting device for electronic components, including a workbench 1, a feeding device 4 and a feeding device 5 located on the workbench 1 for automatic feeding. A shearing mechanism 2 for positioning and shearing the pins of the electronic device and a bending mechanism 3 for assisting the shearing mechanism 2 to accurately shear the pins of the electronic device are arranged on the workbench 1; the shearing mechanism 2 includes a base 21 located on the workbench 1, an electric slide 22 that moves up and down is arranged on the base 21, a hydraulic shearing knife 26 that moves synchronously with the electric slide 22 is arranged on one side of the electric slide 22, and a positioning plate 27 that slides on the same horizontal plane as the hydraulic shearing knife 26 is arranged on one side of the hydraulic shearing knife 26; a shearing table 23 that cooperates with the feeding device 5 for feeding is arranged below the electric slide 22; an electric slide rail 24 is arranged on the base 21, the electric slide 22 slides on the electric slide rail 24, a pressing plate for fixing the electronic device is arranged below the electric slide 22, a scale rod 25 for the hydraulic shearing knife 26 to slide is arranged on one side of the electric slide 22, both the hydraulic shearing knife 26 and the positioning plate 27 are connected through the scale rod 25, the positioning plate 27 moves with the hydraulic shearing knife 26, and the positioning plate 27 is movable on the hydraulic shearing knife 26;

[0030] Referring to Figure 1 , Figure 2 and Figure 3 , the feeding device 4 can screen and correct the position of the electronic device, and then feed it onto the feeding device 5. The feeding device 5 can automatically feed the electronic device and automatically feed the electronic device onto the shearing table 23. Referring to Figure 3 , control the electric slide 22 to move downward on the electric slide rail 24, so that the pressing plate below the electric slide 22 contacts and presses the electronic device, keeping the electronic device stable and avoiding displacement of the electronic device when shearing the pins, resulting in failure of pin shearing;

[0031] In addition, before the electric slide 22 drives the pressing plate to move downward to stabilize the electronic device, the positioning plate 27 and the hydraulic shearing knife 26 can be moved on the scale rod 25, thereby adjusting the position of the hydraulic shearing knife 26 to control the shearing length of the pins of the electronic device, and at the same time adjusting the distance between the positioning plate 27 and the hydraulic shearing knife 26. Then, after the electric slide 22 drives the pressing plate to move downward to stabilize the electronic device, the positioning plate 27 can press down a part of the pins of the electronic device, avoiding over-shearing or inaccurate cutting position when the hydraulic shearing knife 26 shears the pins of the electronic device; thus, cooperating with the pressing plate to stabilize the electronic device, the pins of the electronic device can be sheared more accurately, improving the shearing quality of the pins of the electronic device;

[0032] The bending mechanism 3 includes a sliding seat 32 that slides on the shearing table 23. One side of the sliding seat 32 is provided with an electric push rod 31 for driving its movement. A groove is formed at the bottom of the shearing table 23. A gas storage chamber 33 for accommodating gas is arranged on the sliding seat 32. A piston cylinder 36 is communicated with the bottom of the gas storage chamber 33. A piston rod 37 is arranged inside the groove, and when the piston rod 37 moves inside the piston cylinder 36, it pushes the gas inside the piston cylinder 36 to move; One side of the gas storage chamber 33 is provided with a through pipe 35 for wrapping the pins of electronic devices. An air bag 312 communicated with the gas storage chamber 33 is arranged inside the through pipe 35; One side of the sliding seat 32 is provided with a shearing seat 38 that moves synchronously with the sliding seat 32. A push plate 311 slides inside the shearing seat 38. A third gear 310 is arranged on one side of the groove. One side of the shearing seat 38 is provided with a gear 39 that meshes with the third gear 310 and rotates when the shearing seat 38 moves. One side of the gear 39 is rotatably connected to a power storage shaft 313. The power storage shaft 313 stores power when it rotates following the gear 39. When the gear 39 rotates in the reverse direction and cannot drive the power storage shaft 313 to rotate, the power storage shaft 313 releases power and at the same time drives the push plate 311 to move upward to squeeze the pins and bend them; The sliding seat 32 slides inside the shearing table 23. When the sliding seat 32 slides inside the shearing table 23, the sliding seat 32 drives the piston cylinder 36 to move, and then the piston rod 37 pushes the gas inside the piston cylinder 36 to move. When the gas inside the piston cylinder 36 moves into the gas storage chamber 33 and reaches a certain amount, the gas inside the gas storage chamber 33 enters the air bag 312 and causes the air bag 312 to expand and wrap and squeeze the pins of the electronic components. The third gear 310 is arranged on a part of one side of the groove, and the gear 39 meshes with the third gear 310. When the gear 39 rotates by meshing with the third gear 310, it will drive the power storage shaft 313 to rotate. When the gear 39 rotates in the reverse direction, it will not drive the power storage shaft 313 to rotate. The power storage shaft 313 is rotatably arranged on the shearing seat 38. A torsion spring for storing power when rotating is arranged on the power storage shaft 313. A first gear is arranged on the surface of the power storage shaft 313. The push plate 311 moves inside the shearing seat 38. A second gear is arranged on one side of the push plate 311. The first gear is movably connected to the second gear;

[0033] Refer to Figures 4 to 8 , before pressing and stabilizing the electronic device without shearing, the electric push rod 31 can be controlled to drive the sliding seat 32 to move. When the sliding seat 32 moves inside the shearing table 23, the sliding seat 32 drives the piston cylinder 36 to move, and then the piston rod 37 pushes the gas inside the piston cylinder 36 to move, so that the gas moves into the gas storage chamber 33. When the sliding seat 32 moves to a certain position, when the internal pressure of the gas storage chamber 33 changes to a certain value, the pressure valve on the gas storage chamber 33 will open, and the gas will be filled into the air bag 312 to make the air bag 312 expand; In addition, refer to Figure 4 and Figure 5, before the valve opens when the internal pressure of the air storage chamber 33 has not reached a certain value, the redundant pins of the electronic device will extend into the interior of the through pipe 35, and at this time, the airbag 312 is not inflated; after the internal pressure of the air storage chamber 33 changes to a certain value, the airbag 312 is inflated and expanded to wrap and squeeze the pins of the electronic device. At the same time, in cooperation with the electronic device being squeezed and stabilized by the pressing plate, after the airbag 312 is inflated and expanded, it can straighten the bent pins to a nearly straight state. Thus, during the process of calculating the length when shearing the pins of the electronic device, it is more accurate, avoiding the bent state of the electronic device from affecting the judgment of the shearing position;

[0034] In addition, the airbag 312 is inflated and expanded to wrap and squeeze the pins of the electronic device. At the same time, in cooperation with the electronic device being squeezed and stabilized by the pressing plate, it can stabilize the entire electronic device and its pins, avoiding displacement of the pins due to pressure during shearing, resulting in uneven shearing cuts of the pins of the electronic device and affecting the shearing quality;

[0035] In addition, after the airbag 312 is inflated and expanded to squeeze the pins, the electric push rod 31 can be controlled to move backward a small distance. Thus, while the airbag 312 is inflated and expanded to squeeze the pins, the pins can be straightened, further improving the straightness of the pins.

[0036] In addition, refer to Figures 4 to 8, during the movement of the sliding seat 32, the sliding seat 32 drives the shearing seat 38 to move, and the shearing seat 38 drives the gear 39 to move. Since the gear 39 meshes with the third gear teeth 310, during the process of the shearing seat 38 driving the gear 39 to move, the gear 39 rotates through the third gear teeth 310. When the gear 39 rotates along this direction following the shearing seat 38, the gear 39 will drive the energy storage shaft 313 to rotate. Because the first gear teeth are movably connected to the second gear teeth, but when the energy storage shaft 313 rotates at this time, it will drive the push plate 311 to move downward. However, the push plate 311 is located inside the shearing seat 38, so the push plate 311 cannot move downward. Therefore, when the gear 39 rotates, the energy storage shaft 313 cannot rotate, and at this time, the torsion spring is compressed to store energy; after the shearing seat 38 moves to a certain position, at this time, the third gear teeth 310 are no longer meshed with the gear 39. However, at this time, there is a positioning plate 27 on the push plate 311, so the push plate 311 cannot move. Then, the hydraulic shearing knife 26 is started to shear the pins of the electronic device. After the shearing is completed, the electric push rod 31 drives the sliding seat 32 to start moving in the reverse direction. The sliding seat 32 drives the shearing seat 38 to move in the reverse direction. The shearing seat 38 drives the push plate 311 to move out from under the positioning plate 27. At this time, the torsion spring will start to release force, and the torsion spring will drive the energy storage shaft 313 to rotate in the reverse direction. Since the first gear teeth are movably connected to the second gear teeth, the energy storage shaft 313 will drive the push plate 311 to move upward. The upward movement of the push plate 311 will squeeze the pins, forcing the pins to bend, thereby automatically performing bending processing on them, saving the workload of the staff. At the same time, with the design of the positioning plate 27 pressing part of the pins, it can ensure that there is a distance between the bent part and the root of the pins, avoiding bending the pins from the root when bending the pins manually, resulting in pin breakage and increased costs.

[0037] Working principle: The feeding device 4 can screen and correct the position of the electronic device, and then feed it onto the feeding device 5. The feeding device 5 can automatically feed the electronic device and automatically feed the electronic device onto the shearing table 23; control the electric sliding seat 22 to move downward on the electric slide rail 24, so that the pressing plate below the electric sliding seat 22 contacts and presses the electronic device to keep the electronic device stable. Before the electric sliding seat 22 drives the pressing plate to move downward to stabilize the electronic device, the positioning plate 27 and the hydraulic shearing knife 26 can be moved on the scale rod 25, thereby adjusting the position of the hydraulic shearing knife 26 to control the shearing length of the pins of the electronic device, and at the same time adjusting the distance between the positioning plate 27 and the hydraulic shearing knife 26. Then, after the electric sliding seat 22 drives the pressing plate to move downward to stabilize the electronic device, the positioning plate 27 can press part of the pins of the electronic device;

[0038] Before the electronic device is pressed and stabilized but not sheared, the electric push rod 31 is controlled to drive the slide 32 to move. When the slide 32 moves inside the shearing table 23, the slide 32 drives the piston cylinder 36 to move, and then the piston rod 37 pushes the gas inside the piston cylinder 36 to move, so that the gas moves to the inside of the gas storage chamber 33. When the slide 32 moves to a certain position, the pressure inside the gas storage chamber 33 changes to a certain value, and the pressure valve on the gas storage chamber 33 will open, and the gas will be filled into the inside of the air bag 312, so that the air bag 312 expands;

[0039] Before the pressure inside the air storage chamber 33 reaches a certain value and the valve opens, the excess pins of the electronic device will extend into the interior of the through tube 35, and the airbag 312 is not inflated at this time; after the pressure inside the air storage chamber 33 changes to a certain value, the airbag 312 inflates and will wrap and squeeze the pins of the electronic device, while cooperating with the electronic device to be squeezed and stabilized by the pressing plate, the airbag 312 can correct the bent pins after inflation, making them close to a straight state.

[0040] During the movement of the slide 32, the slide 32 drives the shear seat 38 to move, and the shear seat 38 drives the gear 39 to move. Since the gear 39 is meshed with the third gear tooth 310, the gear 39 rotates through the third gear tooth 310 during the movement of the shear seat 38. When the gear 39 rotates along this direction following the shear seat 38, the gear 39 drives the power storage shaft 313 to rotate, because the first gear tooth is movably connected to the second gear tooth. However, at this time, when the power storage shaft 313 rotates, it drives the push plate 311 to move downward. However, the push plate 311 is located inside the shear seat 38, so the push plate 311 cannot move downward. Therefore, when the gear 39 rotates, the power storage shaft 313 cannot rotate, and at this time, the torsion spring performs compression and power storage.

[0041] After the shear seat 38 moves to a certain position, the third gear tooth 310 is no longer engaged with the gear 39. However, there is a positioning plate 27 on the push plate 311 at this time, so the push plate 311 cannot move. Then, the hydraulic shear knife 26 is started to shear the pins of the electronic device. After the shearing is completed, the electric push rod 31 drives the slide seat 32 to start moving in the opposite direction, and the slide seat 32 drives the shear seat 38 to move in the opposite direction. The shear seat 38 drives the push plate 311 to disengage from the bottom of the positioning plate 27. At this time, the torsion spring will begin to release force, and the torsion spring will drive the force storage shaft 313 to reverse. Since the first gear tooth is movably connected to the second gear tooth, the force storage shaft 313 will drive the push plate 311 to move upward, and the upward movement of the push plate 311 will squeeze the pins, forcing the pins to bend.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
