Description

Technical Field

[0001] The invention relates to the field of automatic pin bending equipment for electronic components, and in particular to a pin shearing and bending device and a working method and a production line thereof. Background Art

[0002] The diodes, rectifier bridges and field effect transistors assembled on the heat sink module need to be assembled on the heat sink by screw fastening, and the pins need to be inserted into the through holes of the PCB board for wave soldering. However, the pins of these components are in a vertical state when they are received, and they cannot be directly used for assembly. They need to be bent before assembly. In addition, the number of pins of this type of component is more than 2, and the precision requirements are extremely high. A slight deviation in the bending angle will cause the subsequent process to fail to be inserted, and manual operation is too uncontrollable, so equipment is generally used for automatic bending.

[0003] In the existing pin shearing and bending device, the electronic components are moved between the pin shearing processing position and the pin bending processing position by the clamping parts, which has a complex structure, low efficiency and is easy to cause the electronic components to be damaged by the clamping. In addition, the existing pin shearing and bending device has a large equipment volume and the position of the material discharged at the discharge port is uncontrollable, and it is impossible to achieve parallel connection with other automated equipment. Therefore, it is very necessary to develop a simple and compact electronic component automatic pin bending mechanism. Summary of the invention

[0004] The first object of the present invention is to provide a pin shearing and bending device which can ensure the bending accuracy and improve the production efficiency and has a simple structure, is compact and light.

[0005] The second object of the present invention is to provide a production line having the above-mentioned pin shearing and bending device.

[0006] The third object of the present invention is to provide a working method of the above-mentioned pin shearing and bending device.

[0007] To achieve the above-mentioned purpose, the present invention provides a pin shearing and bending device, including a workbench, a shearing assembly, a bending assembly and a clamping assembly; a product limiting slide is arranged on the workbench, and the product limiting slide includes a feeding section, a displacement section and a discharging section connected in sequence, the feeding section and the discharging section both extend along the X-axis direction, the displacement section extends along the Y-axis direction, the feeding section is provided with a shearing foot preparation position, the feeding section is provided with a shearing foot processing position at one end close to the displacement section, the discharging section is provided with a bending foot processing position at one end close to the displacement section, and the discharging section is provided with a material picking position at one end away from the displacement section; the shearing assembly includes a shearing foot blade and a shearing foot driving member, the bending assembly includes a bending foot blade and a bending foot driving member, the shearing foot blade is arranged toward the shearing foot processing position, the shearing foot driving member drives the shearing foot blade to move, the bending foot blade is arranged toward the bending foot processing position, and the bending foot driving member drives the bending foot blade to move; the pin shearing The bending device also includes a first pushing assembly, a second pushing assembly and a third pushing assembly; the first pushing assembly includes a first pushing part and a first pushing driving member, the first pushing part is arranged near the shearing foot preparation position, and the first pushing driving member drives the first pushing part to move along the X-axis direction; the second pushing assembly includes a second pushing part and a second pushing driving member, the second pushing part is arranged near the shearing foot processing position, and the second pushing driving member drives the second pushing part to move along the Y-axis direction; the third pushing assembly includes a third pushing part and a third pushing driving member, the third pushing part is arranged near the bending foot processing position, and the third pushing driving member drives the third pushing part to move along the X-axis direction; the clamping assembly includes a shearing clamping member and a bending clamping member, the shearing clamping member is arranged near the shearing foot processing position and can move toward the shearing foot processing position, and the bending clamping member is arranged near the bending foot processing position and can move toward the bending foot processing position.

[0008] It can be seen from the above scheme that, first, after the electronic components are sent into the foot shearing preparation position, the first pushing drive drives the first pushing part to move along the positive direction of the X-axis, and the first pushing part pushes the electronic components from the foot shearing preparation position to the foot shearing processing position, and the first pushing part is reset; then, the shearing and pressing part moves in the negative direction along the Z-axis to press the electronic components; then, the foot shearing drive drives the foot shearing cutter head to move in the negative direction of the Z-axis to cut off the redundant pins on the electronic components, and then the foot shearing cutter head and the shearing and pressing part are reset; then, the second pushing drive drives the second pushing part to move in the positive direction of the Y-axis, and the second pushing part pushes the electronic components from the foot shearing processing position to the foot bending processing position; then, the bending and pressing part moves in the negative direction of the Z-axis to press the electronic components; then, the foot bending drive drives the foot bending cutter head to move in the positive direction of the Z-axis and bends the pins of the electronic components, and then the foot bending cutter head and the bending and pressing part are reset; finally, the third pushing drive drives the third pushing part to move in the negative direction of the X-axis, and the third pushing part pushes the electronic components from the foot bending processing position to the material picking position. The picker at the next workstation takes away the processed electronic components and sends them to the next process.

[0009] A U-shaped product limiting slot is set on the workbench to limit the moving path of the electronic components. At the same time, the electronic components are pushed to move horizontally between the various workstations through the first pushing assembly, the second pushing assembly and the third pushing assembly. The structure is simple and the work efficiency is high. At the same time, the shearing preparation position, the shearing processing position, the bending processing position and the material picking position are dispersedly arranged in the product limiting slot on the workbench. The stroke between two adjacent workstations is short, so that the space can be fully utilized, and the shearing assembly, the bending assembly, the clamping assembly and the three pushing parts are more reasonably and compactly arranged around the workbench, thereby greatly reducing the overall space occupied by the pin shearing and bending device, realizing the miniaturization of the overall structure, and facilitating its serial connection between the feeding mechanism and the mounting module, thereby realizing the online bending operation of the electronic components.

[0010] A preferred solution is that the first pushing component and the shearing component are respectively arranged on opposite sides of the workbench along the X-axis direction, and the first pushing portion and the shearing foot blade are arranged opposite to each other along the X-axis direction.

[0011] It can be seen that in this way, the first pushing portion can directly push the electronic component to the bending foot processing position along the X-axis, and the foot cutting blade is facing the bending foot processing position, which can facilitate the foot cutting blade to cut the excess part of the electronic component pin.

[0012] A further solution is that the first pushing portion extends along the X-axis direction, and the first pushing portion is slidably matched with the feeding section.

[0013] It can be seen that the first pushing portion and the feeding section are slidably matched to ensure the stability of the pushing process.

[0014] A preferred solution is that the second pushing portion extends along the Y-axis direction, and the second pushing portion is slidably matched with the transposition segment.

[0015] This shows that the stability of the pushing process of the second pushing unit is guaranteed.

[0016] A preferred solution is to provide a limiting portion on the side of the material taking position away from the shearing foot processing position.

[0017] It can be seen that the setting of the limit part can accurately position the electronic components sent to the material picking position, so as to facilitate the subsequent workstations to pick up materials from there.

[0018] A preferred solution is that the clamping assembly further includes a clamping drive, which drives the shearing clamping member and the bending clamping member to move along the Z-axis direction.

[0019] It can be seen that the shearing clamp and the bending clamp are driven by the same component, which can further simplify the structure and reduce costs.

[0020] A preferred solution is that the pin shearing and bending device also includes a feeding guide rail, which includes a feed end and a discharge end, the discharge end is close to the shearing pin preparation position, and the discharge end is located on the side of the shearing pin preparation position away from the discharge section in the Y-axis direction. From the feed end to the discharge end, the feeding guide rail is inclined from top to bottom.

[0021] It can be seen that the inclined setting of the feeding guide rail makes it easier for electronic components to automatically flow into the shearing preparation position under the action of their own gravity, eliminating the need for manual loading, thereby further improving production efficiency.

[0022] A preferred solution is that the pin shearing and bending device also includes a support, the clamping assembly also includes a mounting seat, the mounting seat and the support are slidably connected along the Z-axis direction, and the shearing clamping piece and the bending clamping piece are both installed on the mounting seat.

[0023] It can be seen that effective support and guidance of the shearing and bending clamping parts are achieved to ensure the accuracy of their positions after movement.

[0024] A further solution is that at least one of the shearing clamping member and the bending clamping member includes a support column, an elastic member and a pressure head, the support column extends along the Z-axis direction, the positive end of the support column in the Z-axis is connected to the mounting seat, the elastic member is sleeved on the support column, the pressure head is located at the negative end of the support column in the Z-axis and abuts against the elastic member, the pressure head is slidably connected to the support column, and the restoring force of the elastic member forces the pressure head to move toward the product limiting slide groove.

[0025] It can be seen that the contact mode between the pressing piece and the electronic component is elastic contact, thereby preventing the electronic component from being crushed.

[0026] A further solution is that a pressure plate is provided on the mounting seat, and the pressure plate is located on the positive side of the Z-axis of the bending foot processing position. In the X-axis direction, the pressure plate is close to the bending foot cutter head, and the surface of the bending foot cutter head facing the pressure plate is parallel to the main surface of the pressure plate. A pin accommodating gap can be formed between the pressure plate and the bending foot cutter head.

[0027] It can be seen that when the bending clamp moves downward to press the electronic component body, the pressure plate moves downward and presses the pin close to the bending position. Then, the bending blade moves upward to bend the pin, and the bent part is located in the pin accommodating gap. Therefore, the cooperation between the pressure plate and the bending blade can improve the accuracy of the pin bending angle, thereby improving product quality.

[0028] A preferred solution is that the shear foot driving member drives the shear foot cutter head to move along the Z-axis direction.

[0029] It can be seen that the electronic components are placed flat on the workbench, and the shearing cutter head moves along the Z-axis direction to shear the pins, thereby ensuring the stability of the placement of the electronic components and improving the shearing accuracy.

[0030] A preferred solution is that the bent foot driving member drives the bent foot cutter head to move along the Z-axis direction.

[0031] It can be seen that the electronic components are placed flat on the workbench, and the bending blade moves along the Z-axis direction to bend the pins, ensuring the accuracy of the pin bending angle.

[0032] To achieve the above second objective, the present invention provides a production line, including the above pin shearing and bending device.

[0033] To achieve the third purpose, the present invention provides a working method of a pin shearing and bending device, the pin shearing and bending device is the above-mentioned pin shearing and bending device, and the working method includes: a feeding step: after the first electronic component is fed into the shearing preparation position, the first pushing driving member drives the first pushing part to move along the positive direction of the X-axis, the first pushing part pushes the first electronic component from the shearing preparation position to the shearing processing position, and the first pushing part is reset; a one-time clamping step: the shearing clamping member moves along the negative direction of the Z axis to clamp the first electronic component; a shearing step: the shearing driving member drives the shearing blade to move along the negative direction of the Z axis to cut off the excess length of the first electronic component pin, and then the shearing blade and the shearing and pressing parts are reset; a displacement step: the second pushing driving part drives the second pushing part to move along the positive direction of the Y axis, the second pushing part pushes the first electronic component from the shearing foot processing position to the bending foot processing position, and the second pushing part is reset; a secondary clamping step: the bending and pressing part moves along the negative direction of the Z axis to clamp the first electronic component; a bending step: the bending foot driving part drives the bending foot cutter head to move along the positive direction of the Z axis and bends the pin of the first electronic component, and then the bending foot cutter head and the bending and pressing part are reset; a discharging step: the third pushing driving part drives the third pushing part to move along the negative direction of the X axis, the third pushing part pushes the first electronic component from the bending foot processing position to the material taking position, and the third pushing part is reset.

[0034] A preferred solution is that after the feeding step is completed, the second electronic component enters the pin cutting preparation position, and after the first electronic component enters the position change step, the second electronic component enters the feeding step.

The bending foot cutter head 41 is set toward the bending foot processing position 27, and the bending foot driving member 42 drives the bending foot cutter head 41 to move along the Z-axis direction, and the Z-axis direction is the vertical direction.

[0045] The first push assembly 6 includes a first push portion 61 and a first push drive member 62. The first push assembly 6 and the shear assembly 3 are respectively arranged on opposite sides of the workbench 2 along the X-axis direction. The first push portion 61 is arranged near the shearing foot preparation position 25, and the first push portion 61 and the shearing foot cutter head 31 are arranged opposite to each other along the X-axis direction. The first push portion 61 extends along the X-axis direction, the first push portion 61 slides with the feeding section 22, and the first push drive member 62 drives the first push portion 61 to move along the X-axis direction. The second push assembly 7 includes a second push portion 71 and a second push drive member (not shown). The second push portion 71 is arranged near the shearing foot processing position 26, the second push portion 71 extends along the Y-axis direction, the second push portion 71 slides with the transposition section 23, and the second push drive member drives the second push portion 71 to move along the Y-axis direction. The third pushing assembly 8 includes a third pushing portion 81 and a third pushing driving member 82. The third pushing portion 81 is disposed near the bending leg processing position 27. The third pushing driving member 82 drives the third pushing portion 81 to move along the X-axis direction. In addition, the third pushing portion 82 extends along the Y-axis direction.

[0046] The clamping assembly 5 includes a mounting seat 51, a pressing plate 52, a clamping driving member 53, a shearing clamping member 54 and a bending clamping member 55. The support 21 is relatively fixed to the workbench 2. The mounting seat 51 is slidably connected with the support 21 along the Z-axis direction. The shearing clamping member 54 and the bending clamping member 55 are both mounted on the mounting seat 51. The shearing clamping member 54 is arranged near the shearing foot processing position 26, and the bending clamping member 55 is arranged near the bending foot processing position 27. The clamping driving member 53 drives the shearing clamping member 54 and the bending clamping member 55 to move along the Z-axis direction, thereby driving the shearing clamping member 54 to move toward the shearing foot processing position 26 and driving the bending clamping member 55 to move toward the bending foot processing position 27.

[0047] The shearing clamp 54 and the bending clamp 55 both include a support column 541, an elastic member 542 and a pressure head 543. The support column 541 extends along the Z-axis direction. The positive end of the support column 541 in the Z-axis is connected to the mounting seat 51. The elastic member 542 is sleeved on the support column 541. The pressure head 543 is located at the negative end of the support column 541 in the Z-axis and abuts against the elastic member 542. The pressure head 543 is slidably connected to the support column 541. The restoring force of the elastic member 542 forces the pressure head 543 to move toward the product limiting slide 21. The contact mode between each clamp and the electronic component 10 is elastic contact, thereby preventing the device body of the electronic component 10 from being crushed. The positive end of the Z-axis of the pressure plate 52 is connected to the mounting seat 51 through a spring 521 to ensure that the pressure plate 52 is in elastic contact with the pins of the electronic component 10, thereby preventing the pins of the electronic component 10 from being crushed.

[0048] The pressing plate 52 is arranged on the mounting seat 51, and the pressing plate 52 is located on the positive side of the Z axis of the bending foot processing position 27. In the X axis direction, the pressing plate 52 is close to the bending foot blade 41, and the surface of the bending foot blade 41 facing the pressing plate 52 is parallel to the main surface of the pressing plate 52. A pin accommodating gap 40 can be formed between the pressing plate 52 and the bending foot blade 41. When the bending clamp 55 moves downward to press the device body 101 of the electronic component 10, the pressing plate 52 moves downward and presses the pin near the bending position. Then, the bending foot blade 41 moves upward to bend the pin, and the bending portion 102 of the electronic component 10 is located in the pin accommodating gap 40. Therefore, the cooperation between the pressing plate 52 and the bending foot blade 41 can improve the accuracy of the pin bending angle, thereby improving the product quality.

[0049] The feeding guide rail 1 is arranged on one side of the workbench 2, and the feeding guide rail 1 includes a feeding end 11 and a discharging end 12, the discharging end 12 is close to the shearing foot preparation position 25, and the discharging end 12 is located on the side of the shearing foot preparation position 25 away from the discharging section 24 in the Y-axis direction, and the feeding guide rail 1 is inclined from top to bottom from the feeding end 11 to the discharging end 12. In this way, it is convenient for the electronic components 10 to automatically flow into the shearing foot preparation position 25 under the action of their own gravity, without manual loading, and further improving production efficiency.

[0050] Before starting the pin shearing and bending device, the electronic components 10 are arranged in order in the feeding track, and the pins of the electronic components 10 are facing the same side, the first pushing part 61 is at the negative side of the X-axis of the pin shearing preparation position 25, the second pushing part 71 is at the negative side of the Y-axis of the pin shearing processing position 26, and the third pushing part 81 is at the positive side of the X-axis of the pin bending processing position 27, and the shearing clamp 54, the bending clamp 55 and the pressure plate 52 are all at the highest position of the stroke.

[0051] The working method of the pin shearing and bending device specifically includes the following steps.

[0052] Feeding steps: After the first electronic component 10 is fed into the cutting preparation position 25, the first pushing drive 62 drives the first pushing part 61 to move in the positive direction along the X-axis. After the first pushing part 61 pushes the first electronic component 10 from the cutting preparation position 25 to the cutting processing position 26, the first pushing part 61 is reset. After the first pushing part 61 is reset, the second electronic component 10 enters the cutting preparation position 25 along the feeding track.

[0053] The first pressing step: the shearing pressing member 54 moves in the negative direction along the Z axis to press the first electronic component 10 on the shearing foot processing position 26 .

[0054] Shearing steps: The shearing drive drives the shearing head 31 to move along the negative direction of the Z axis to cut off the excess length of the pin on the first electronic component 10 on the shearing processing position 26, and then the shearing head 31 and the shearing clamp 54 are reset to release the first electronic component 10 on the shearing processing position 26.

[0055] Transposition step: the second pushing driving member drives the second pushing part 71 to move in the positive direction along the Y-axis, the second pushing part 71 pushes the first electronic component 10 from the foot cutting processing position 26 to the foot bending processing position 27, and the second pushing part 71 is reset. After the second pushing part 71 is reset, the second electronic component 10 enters the feeding step, and the first pushing part 61 pushes the second electronic component 10 from the foot cutting preparation position 25 to the foot cutting processing position 26.

[0056] Secondary clamping step: the clamping drive 53 drives the mounting seat 51 and drives the pressing plate 52, the shearing clamp 54 and the bending clamp 55 to move along the negative direction of the Z axis, the bending clamp 55 presses the device body of the first electronic component 10, and the negative end of the Z axis of the pressing plate 52 presses the pin body of the first electronic component 10. At the same time, the second electronic component 10 enters the primary clamping step, that is, the shearing clamp 54 presses the second electronic component 10.

[0057] Bending step: the bending driving member 42 drives the bending blade 41 to move forward along the Z axis, and after the bending blade 41 cooperates with the pressing plate 52 to bend the pins of the first electronic component 10, the bending blade 41 and the bending pressing member 55 are reset. At the same time, the second electronic component 10 enters the shearing step, that is, the shearing blade 31 shears off the redundant pins on the second electronic component 10.

[0058] Discharging step: the third pushing driving member 82 drives the third pushing part 81 to move along the negative direction of the X-axis, and the third pushing part 81 pushes the first electronic component 10 from the bending foot processing position 27 to the material picking position 28. After the third pushing part 81 is reset, the second electronic component 10 enters the position change step, and the second pushing part 71 pushes the second electronic component 10 from the cutting foot processing position 26 to the bending foot processing position 27.

[0059] The above steps are repeated, and each electronic component 10 completes the shearing and bending processes after sequentially passing through the above-mentioned feeding step, primary pressing step, shearing step, transposition step, secondary pressing step, bending step and discharge step. Since the second electronic component 10 enters the feeding step while the previous electronic component 10 enters the transposition step, a pressing assembly 5 can simultaneously execute the secondary pressing step of the previous electronic component 10 and the primary pressing step of the next electronic component 10. The components are compactly positioned to reduce the occupied space, and the components cooperate in an orderly manner, which greatly improves the production efficiency.

[0060] As can be seen from the above, a U-shaped product limiting slot is set on the workbench to limit the moving path of the electronic components. At the same time, the electronic components are pushed horizontally between the workstations through the first pushing assembly, the second pushing assembly and the third pushing assembly. The structure is simple and the work efficiency is high. At the same time, the shearing preparation position, the shearing processing position, the bending processing position and the material picking position are dispersedly arranged in the product limiting slot on the workbench. The stroke between two adjacent workstations is short, so that the space can be fully utilized, and the shearing assembly, the bending assembly, the clamping assembly and the three pushing parts are more reasonably and compactly arranged around the workbench, thereby greatly reducing the overall space occupied by the pin shearing and bending device, realizing the miniaturization of the overall structure, and facilitating its serial connection between the feeding mechanism and the mounting module, thereby realizing the online bending operation of electronic components.

[0061] In addition, the clamping assembly may also include two clamping driving members, which respectively drive the shear clamping member and the bending clamping member to move. Alternatively, one of the shear clamping member and the bending clamping member may be composed of a support column, an elastic member and a pressure head. The pressure head may also be made of an elastic material such as silicone. The elastic member may be a spring or may be made of an elastic material. Each driving member may adopt a driving mechanism that drives the components to move, such as a cylinder or a motor. The support may also be fixed on the workbench or may be integrally formed with the workbench. The width of the shearing blade head and the bending blade head may be changed as needed, and the size may be appropriately increased to be suitable for electronic components with different numbers of pins. The above changes can also achieve the purpose of the present invention.

[0062] Finally, it should be emphasized that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
