Description

Technical Field

[0001] This invention relates to the field of electronic component manufacturing equipment technology, and specifically to a continuous bending and forming device for cutting the leads of surface mount electronic components. Background Technology

[0002] Electronic components include surface mount resistors, surface mount capacitors, surface mount diodes, and other electronic components. The leads of electronic components are mainly divided into inward-folded leads and outward-folded leads. The manufacturing process of electronic components with inward-folded leads is as follows: First, the chip is soldered onto the integrated leads. Then, insulating material is wrapped around the chip and some of the leads. Next, the integrated leads are cut into multiple individual components. Then, the leads of the individual components are bent once and twice in sequence so that one end of the lead touches the bottom surface of the electronic component.

[0003] Currently, when performing processes such as cutting, bending, and bending of inward-folded lead-type electronic components, the components need to be placed on different equipment, resulting in low production efficiency. Moreover, since multiple machines need to be purchased at the same time, a lot of production space is required, leading to high production costs for enterprises. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a continuous bending and forming device for cutting pins of surface mount electronic components. It can perform the processes of cutting, bending, and bending pins on the same equipment, greatly improving the production efficiency of electronic components and reducing the production costs of enterprises.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A surface mount electronic component pin cutting and continuous bending forming device includes a lower assembly, an upper assembly, and a driving component for driving the upper assembly to move up and down. The lower assembly includes a lower mounting base and a lower cutting and bending assembly disposed on the lower mounting base. The lower cutting and bending assembly includes a component positioning base fixedly disposed on the lower mounting base, a lower blade plate fixedly disposed on opposite sides of the component positioning base, a lower bending insert disposed between the component positioning base and the lower blade plate, a linkage seat that can drive the lower bending insert to move up and down relative to the component positioning base, and a first return spring that makes the linkage seat always have a downward tendency.

The upper cutting and bending assembly includes a pressing base for fixing electronic components to component positioning bases, upper blades disposed on opposite sides of the pressing base, an upper bending insert disposed between the pressing base and the upper blades, and a second return spring that ensures the pressing base always has a downward tendency.

[0008] The upper mounting plate is provided with a downwardly extending connecting rod, and the connecting seat is provided with a connecting hole corresponding to the connecting rod. The connecting rod can be interference-fitted with the connecting hole so that when the connecting rod moves upward, it drives the connecting seat to move upward.

[0009] As a preferred technical solution, the upper end of the component positioning seat is provided with a component positioning groove for placing electronic components, the upper end of the lower blade is provided with a pin positioning groove for the pins of electronic components to extend out, the side of the lower blade away from the component positioning groove forms a lower cutting edge, and the lower end of the upper blade near the pressing seat forms an upper cutting edge corresponding to the lower cutting edge.

[0010] As a preferred technical solution, an elastic element is sleeved on the linkage rod. The elastic element is a plastic ring, and the plastic ring is detachably connected to the linkage rod by screws or bolts.

[0011] As a preferred technical solution, the upper end of the lower bending insert is provided with a downward bending slope that slopes from top to bottom away from the component positioning seat on the side away from the component positioning seat. A bending groove is formed between the lower bending slope and the inner side of the opposite lower blade plate. The shape of the lower end of the upper bending insert is adapted to the shape of the bending groove.

[0012] As a preferred technical solution, the lower component further includes an insert positioning seat, which is located between the linkage seat and the component positioning seat. The linkage seat is located below the lower mounting seat, and the insert positioning seat and the component positioning seat are located at the upper end of the lower mounting seat. The insert positioning seat is fixedly connected to the linkage seat. The first return spring is located between the lower mounting seat and the linkage seat. The side of the insert positioning seat has an upward-through first insert positioning groove, and the side of the component positioning seat has a second insert positioning groove corresponding to the first insert positioning groove. During assembly, the lower bent insert is embedded in the corresponding first insert positioning groove and second insert positioning groove, and the lower blade plate is blocked outside the first insert positioning groove and second insert positioning groove. The lower bent insert can slide up and down relative to the second insert positioning groove.

[0013] As a preferred technical solution, the lower end of the bent insert is provided with a laterally extending limiting protrusion, and the side of the insert positioning seat is provided with a third insert positioning groove corresponding to the limiting protrusion. The third insert positioning groove is located at the lower end of the first insert positioning groove and is connected to the first insert positioning groove.

[0014] As a preferred technical solution, the lower bending insert is provided in multiple ways. The side of the insert positioning seat is provided with a first insert positioning groove corresponding to each of the multiple lower bending inserts. The side of the component positioning seat is provided with a second insert positioning groove corresponding to each of the multiple first insert positioning grooves. The multiple first insert positioning grooves and the multiple second insert positioning grooves are arranged in a straight horizontal line.

[0015] As a preferred technical solution, the lower end of the component positioning seat is provided with several downwardly extending guide rods, and the insert positioning seat is provided with guide holes corresponding to the guide rods. The guide holes pass through the upper and lower ends of the insert positioning seat, and the length of the guide rod is greater than the height of the insert positioning seat. During assembly, the guide rod passes through the guide hole and abuts against the lower mounting seat. The insert positioning seat can be movably installed below the component positioning seat through the cooperation of the guide rod and the guide hole.

[0016] As a preferred technical solution, the upper end of the lower mounting base is provided with an upward-opening clamping groove. The insert positioning base, component positioning base, and lower blade plate are all located in the clamping groove. The bottom of the clamping groove is provided with a first through hole that extends vertically. The linkage base is provided with a connecting rod corresponding to the first through hole. The connecting rod is provided with a second through hole that extends vertically. The lower end of the insert positioning base is provided with a fixing hole corresponding to the connecting rod. During assembly, the connecting rod passes through the first through hole from bottom to top and extends into the clamping groove to connect with the insert positioning base.

The upper blade is fixedly installed on both sides of the limiting groove by screws or bolts, and the upper bending insert is clamped between the upper blade and the outer side wall of the limiting groove.

[0018] Compared with existing technologies, this invention has significant advantages and beneficial effects. Specifically, by setting up an upper and lower cutting and bending assembly, the cutting and bending of the pin can be achieved through the cooperation of the upper and lower cutting and bending assemblies. By setting a connecting rod on the upper mounting plate and a connecting seat on the lower mounting plate, and setting a connecting hole on the connecting seat that is interference-fitted with the connecting rod, the lower bending insert is driven to push the pin of the electronic component upward during mold opening, thereby achieving a secondary bending of the pin. Through ingenious structural design, this invention enables the cutting, primary bending, and secondary bending processes of electronic components to be completed in one opening and closing process on the same equipment, improving the production efficiency of electronic components and reducing the production cost of enterprises.

They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0053] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0054] like Figure 1-15 As shown, a continuous bending forming device for cutting the pins of surface mount electronic components includes a lower assembly 100, an upper assembly 200 located above the lower assembly 100, and a driving component (not shown) that drives the upper assembly 200 to move up and down. The lower assembly 100 includes a lower mounting plate 10, a lower mounting seat 20 fixedly disposed on the upper end of the lower mounting plate 10, and a lower cutting and bending assembly 30 disposed on the lower mounting seat 20. The lower cutting and bending assembly 30 includes a component positioning seat 31 fixedly disposed on the lower mounting seat 20, a lower blade plate 32 disposed on opposite sides of the component positioning seat 31, a lower bending insert 33 disposed between the component positioning seat 31 and the lower blade plate 32, a linkage seat 40 that can drive the lower bending insert 33 to move up and down relative to the component positioning seat 31, and a first return spring 35 that makes the linkage seat 40 always have a downward tendency.

[0055] The upper component 200 includes an upper mounting plate 50, an upper mounting base 60 fixedly disposed at the lower end of the upper mounting plate 50, and an upper cutting and bending component 70 disposed on the upper mounting base 60. The upper cutting and bending component 70 includes a pressing base 71, upper blades 72 disposed on opposite sides of the pressing base 71, an upper bending insert 73 disposed between the pressing base 71 and the upper blades 72, and a second return spring (not shown) that makes the pressing base 71 always have a downward tendency to move. The upper mounting plate 50 is provided with a downwardly extending connecting rod 51. The lower end of the connecting rod 51 is provided with an elastic element 52. The connecting base 40 is provided with a connecting hole 42 corresponding to the elastic element 52. The elastic element 52 can be interference-fitted with the connecting hole 42 so that when the connecting rod 51 moves upward, it drives the connecting base 40 to move upward. In order to facilitate the elastic element 52 to enter the connecting hole 42, the upper end of the connecting hole 42 is provided with a guide slope. The upper mounting plate 50 is provided with a linkage rod fixing seat 53. The linkage rod 51 is installed on the upper mounting plate 50 through the linkage rod fixing seat 53. There are four linkage rods 51, and the four linkage rods 51 are symmetrically arranged in pairs.

[0056] In this invention, the elastic element 52 is a plastic ring, which is detachably connected to the connecting rod 51 by screws or bolts. During assembly, one end of the plastic ring abuts against the free end of the connecting rod 51, and the screw or bolt passes through the other end of the plastic ring and is threadedly connected to the connecting rod 51. The screw or bolt head compresses and expands the plastic ring, causing its outer diameter to be larger than the diameter of the connecting rod 51. By providing a detachable elastic element 52, it is easy to replace the elastic element 52, avoiding the decrease in friction due to prolonged use and reducing user production costs. By using screws or bolts to connect the plastic ring to the connecting rod 51, the deformation of the plastic ring can be adjusted by adjusting the stroke of the screw or bolt, thereby adjusting the magnitude of the friction.

[0057] In this invention, the upper end of the lower bending insert 33 is provided with a lower bending slope 331 that is inclined from top to bottom away from the component positioning seat 31 on the side away from the component positioning seat 31. The included angle between the lower bending slope 331 and the inner side of the opposite lower blade plate 32 is less than 90°. A bending groove is formed between the lower bending slope 331 and the inner side of the opposite lower blade plate 32. The shape of the lower end of the upper bending insert 73 is adapted to the shape of the bending groove.

[0058] A linkage seat positioning groove 12 corresponding to the linkage seat 40 is provided between the lower mounting base 20 and the lower mounting plate 10. The linkage seat 40 is embedded in the linkage seat positioning groove 12 and can move up and down within the linkage seat positioning groove 12. Connecting blocks 41 are provided at both ends of the linkage seat 40. The connecting blocks 41 are fixedly connected to the linkage seat 40 by screws or bolts. Connecting holes 42 are provided on the connecting blocks 41, and the connecting blocks 41 are located on both sides of the lower mounting base 20 along its length. The upper mounting plate 50 and the lower mounting plate 10 are respectively provided with an upper limit post 54 and a lower limit post 11 arranged opposite to each other. By setting the limit post 11, the stroke of the upper component 200 and the lower component 100 during mold closing can be limited to prevent over-rushing.

[0059] Specifically, such as Figure 3-5 As shown, the upper end of the component positioning seat 31 is provided with a component positioning groove 311 for placing electronic components 80, and the upper end of the lower blade plate 32 is provided with a pin positioning groove 321 for the pins 81 of the electronic components 80 to extend out. A lower cutting edge is formed on the side of the lower blade plate 32 away from the component positioning groove 311, and an upper cutting edge corresponding to the lower cutting edge is formed on the side of the lower end of the upper blade plate 72 near the pressing seat 71. In this invention, the component positioning groove 311 extends along the length direction of the component positioning seat 31, and the extension length is set according to the length of the integrated electronic component strip, while the number of pin positioning grooves 321 can be set according to the number of electronic components 80 on the electronic component strip.

[0060] Specifically, such as Figure 4-8 As shown, the lower component 100 also includes an insert positioning seat 34, which is located between the linkage seat 40 and the component positioning seat 31. The linkage seat 40 is located below the lower mounting seat 20, and the insert positioning seat 34 and the component positioning seat 31 are located at the upper end of the lower mounting seat 20. The insert positioning seat 34 is fixedly connected to the linkage seat 40, and the component positioning seat 31 is movably mounted on the upper end of the insert positioning seat 34. The first return spring 35 is located between the lower mounting seat 20 and the linkage seat 40. The side of the insert positioning seat 34 is provided with an upward through first insert positioning groove 341, and the side of the component positioning seat 31 is provided with a second insert positioning groove 312 corresponding to the first insert positioning groove 341. During assembly, the lower bent insert 33 is embedded in the corresponding first insert positioning groove 341 and second insert positioning groove 312, and the lower blade plate 32 is blocked outside the first insert positioning groove 341 and second insert positioning groove 312. The lower bent insert 33 can slide up and down relative to the second insert positioning groove 312.

[0061] The lower end of the bent insert 33 is provided with a laterally extending limiting protrusion 332, and the side of the insert positioning seat 34 is provided with a third insert positioning groove 342 corresponding to the limiting protrusion 332. The third insert positioning groove 342 is located at the lower end of the first insert positioning groove 341 and is connected to the first insert positioning groove 341.

[0062] In this invention, multiple downward bending inserts 33 are provided, and the number of downward bending inserts 33 is set based on the number of electronic components 80 to be formed. The side of the insert positioning seat 34 is provided with first insert positioning grooves 341 corresponding one-to-one with the multiple downward bending inserts 33. The side of the component positioning seat 31 is provided with second insert positioning grooves 312 corresponding to the multiple first insert positioning grooves 341 respectively. The multiple first insert positioning grooves 341 and the multiple second insert positioning grooves 312 are arranged horizontally in a straight line. This invention, by separately setting multiple downward bending inserts 33, facilitates the replacement of damaged individual downward bending inserts 33, reducing enterprise production costs. It should be understood that in actual use, the multiple downward bending inserts 33 can also be set as an integral connection structure, or several can be connected as a group.

[0063] Specifically, the lower end of the component positioning seat 31 is provided with several downwardly extending guide rods 313, and the insert positioning seat 34 is provided with guide holes 343 corresponding to the guide rods 313. The guide holes 343 penetrate through the upper and lower ends of the insert positioning seat 34, and the length of the guide rods 313 is greater than the height of the insert positioning seat 34. During assembly, the guide rods 313 pass through the guide holes 343 and abut against the lower mounting seat 20. The insert positioning seat 34 can be movably installed below the component positioning seat 31 through the cooperation of the guide rods 313 and the guide holes 343. In this invention, the spacing between adjacent guide rods 313 is different, which can play a foolproof role and prevent the component positioning seat 31 from being installed backwards.

[0064] The upper end of the lower mounting base 20 is provided with an upward-opening clamping groove 21. The insert positioning base 34, component positioning base 31, and lower blade plate 32 are all located within the clamping groove 21. The bottom of the clamping groove 21 is provided with a first through hole 22 extending vertically. The linkage base 40 is provided with a connecting rod 43 corresponding to the first through hole 22. The connecting rod 43 is provided with a second through hole 44 extending vertically. The lower end of the insert positioning base 34 is provided with a fixing hole 344 corresponding to the connecting rod 43. During assembly, the connecting rod 43 extends from bottom to top through the first through hole 22 into the clamping groove 21 and connects with the insert positioning base 34. Screws or bolts extend from bottom to top through the second through hole 44 and engage with the fixing hole 344. The clamping groove 21 also has openings on opposite sides. Clamping plates 23 are provided at the openings on both sides of the clamping groove 21. The clamping plates 23 are fixedly connected to the lower mounting base 20 by screws or bolts. By providing openings on opposite sides of the clamping groove 21, the installation of the lower cutting assembly 30 can be facilitated.

[0065] In this invention, such as Figure 9-12 As shown, the lower end of the pressing base 71 is provided with a downwardly extending extension plate 711. The lower end of the extension plate 711 is provided with several pressing blocks 712 for fixing electronic components on the component positioning base 31. The spacing of the pressing blocks 712 corresponds to the components on the component strip. The upper mounting base 60 is provided with a vertically penetrating limiting groove 61. During assembly, the extension plate 711 passes through the limiting groove 61 from top to bottom, causing the pressing blocks 712 to extend downward. The upper blade plate 72 is fixedly installed on both sides of the limiting groove 61 by screws or bolts. The upper bending insert 73 is clamped between the upper blade plate 72 and the outer side wall of the limiting groove 61. The lower surface of the upper mounting plate 50 and the upper surface of the pressing base 71 are both provided with spring positioning grooves 55. The two ends of the second reset spring respectively abut against the corresponding spring positioning grooves 55.

[0066] The working process of this invention is as follows:

[0067] like Figure 13-15As shown, the integrated electronic component 80 is first placed on the upper end of the component positioning seat 31, with one end of the pin 81 extending out of the pin positioning groove 321. Then, the upper assembly 200 is controlled to move downward by the drive component. During the downward movement of the upper assembly 200, the pressing block 712, under the action of the second reset spring, first presses and fixes the electronic component 80 onto the component positioning groove 311. Then, the upper blade 72 and the lower blade 32 cooperate to cut the integrated carrier tape with the pin 81 located outside the pin positioning groove 321. Then, the upper bending insert 73 continues to descend and presses down on the cut pin 81 to perform the first bending, so that the pin is formed along the bending groove to form a hook shape. At this time, the elastic element 52 at the lower end of the linkage 51 is embedded in the linkage seat 40. The upper component 200 moves upward under the control of the drive component. Due to the friction between the elastic element 52 and the connecting hole 42, the linkage rod 51 simultaneously drives the linkage seat 40 to move upward. At this time, since the pressing seat 71 still presses against the electronic component under the action of the second return spring, the linkage seat 40 drives the lower bending insert 33 to move upward relative to the component positioning seat 31 through the insert positioning seat 34. The lower bending insert 33 pushes the pin 81 upward, causing the pin 81 to bend upward and the end of the pin to abut against the upper surface of the electronic component 80, thereby realizing the secondary bending forming of the pin 81. When the linkage seat 40 reaches the upper limit of the stroke, the elastic element 52 separates from the connecting hole 42. In order to prevent the lower bending insert 33 from scratching the pin when it pushes upward, the upper end of the lower bending insert 33 near the component positioning seat 31 is provided with an arc chamfer.

[0068] In summary, this invention, by setting up an upper and lower cutting and bending assembly, enables the cutting and primary bending of leads through the cooperation of the upper and lower cutting and bending assemblies. By setting a connecting rod on the upper mounting plate, an elastic element at the lower end of the connecting rod, and a connecting seat on the lower mounting plate with an interference-fit connection hole on the connecting seat, a secondary bending of the leads is achieved during mold opening through the cooperation of the connecting rod and the connecting seat. This invention, through its ingenious structural design, enables the slitting, primary bending, and secondary bending processes of electronic components to be performed on the same equipment, improving the production efficiency of electronic components and reducing the production costs for enterprises.

[0069] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technology of the present invention shall still fall within the scope of the technical solution of the present invention.
