[0002] An integrated circuit is a miniature electronic device or component. Using specific processes, the transistors, resistors, capacitors, inductors, and other components required for a circuit, along with interconnecting wiring, are fabricated on one or several small pieces of semiconductor wafers or dielectric substrates, and then packaged in a casing to form a miniature structure with the required circuit function.

[0003] Currently, there are two main types of integrated circuit packaging in China: flat packaging, where the pins and connecting ribs are connected to the outer frame to form a flat structure, and dual in-line packaging, where the pins on opposite sides of the integrated circuit are bent to form a U-shaped structure.

[0050] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0051] The specific structure is as follows: Figures 1 to 4 As shown.

[0052] This embodiment provides an integrated circuit cutting and forming device, including: a tool holder 1 and at least a pair of moving blades with opposing blades; the moving blades are slidably connected to the tool holder 1, and the moving blades with opposing blades move relative to each other on the tool holder 1 to make the opposing blades approach each other for cutting; the at least a pair of moving blades with opposing blades includes a pair of first moving blades 31, the first moving blades 31 are used to cut the pins of the integrated circuit, and the tool holder 1 is provided with positioning ribs 4, the positioning ribs 4 are located between the pair of first moving blades 31.

[0053] In this embodiment, the dual in-line package integrated circuit is placed on the positioning rib 4. The pins on both sides are located on both sides of the positioning rib 4 and correspond to two of the pair of first moving blades 31 respectively. That is, the first moving blades 31 on both sides cooperate with the positioning rib 4 in between, so that the pins on both sides can be cut off at the same time. The cutting is convenient and quick, saving manpower. At the same time, the flat integrated circuit can also be placed between the first moving blade 31 and the positioning rib 4 for cutting. At this time, the two first moving blades 31 can cut two flat integrated circuits at the same time, improving the cutting efficiency. In addition, this structure can be used for cutting and processing of two types of integrated circuit packages at the same time, which is highly applicable.

[0054] In this embodiment, multiple integrated circuits can also be placed at the positioning rib 4, so that the first moving blade 31 can cut the pins of multiple integrated circuits at the same time, thereby improving the cutting efficiency.

[0055] In the optional technical solution of this embodiment, along the blade extension direction of the first moving blade 31, the positioning rib 4 is provided with at least one protruding positioning part 41 and / or at least one recessed positioning part 42 on the side away from the blade holder 1.

[0056] In this embodiment, the upper surface of the positioning rib 4 is a plane. A raised positioning part 41 and / or a recessed positioning part 42 can be provided on the plane. The dual in-line package integrated circuit can be placed on the raised positioning part 41 or the plane part of the upper surface, or the dual in-line package integrated circuit can be placed on the recessed positioning part 42 or the plane part of the upper surface. This allows the pins on both sides of the dual in-line package integrated circuit to extend into the cutting position of the first moving blade 31 at different depths, which can result in different pin cutting lengths to meet different needs and improve applicability. At the same time, multiple dual in-line package integrated circuits can be placed on the positioning rib 4. These dual in-line package integrated circuits can be placed on the raised positioning part 41, the plane part of the upper surface, and the recessed positioning part 42 as needed, and pins of different lengths can be cut to meet different needs.

[0057] In this preferred embodiment, both raised positioning portions 41 and recessed positioning portions 42 are simultaneously provided on the positioning rib 4 to improve the diversity of pin cutting length selection. Both the raised positioning portions 41 and the recessed positioning portions 42 are used to position integrated circuits in dual in-line packages with pins of different lengths. When multiple raised positioning portions 41 are provided, their heights may be the same or different; when multiple recessed positioning portions 42 are provided, their depths may be the same or different, further improving the diversity of pin cutting length selection. The distance between the two sides of the positioning rib 4 facing the pair of first moving blades 31 is the same as the distance between the pins on both sides of the dual in-line package integrated circuit.

[0058] In the optional technical solution of this embodiment, a first reset spring 5, a limiting member 6, and a movable clamping plate 7 that cooperates with the positioning rib 4 to clamp the integrated circuit are also included. The movable clamping plate 7 is disposed on the tool holder 1 and is located on the side of the first moving tool 31 away from the tool holder 1. The movable clamping plate 7 has a first through hole 71. One end of the limiting member 6 passes through the first through hole 71 and is connected to the tool holder 1, and the other end is used to restrict the movable clamping plate 7 from moving to the side away from the tool holder 1. The first reset spring 5 is disposed in the first through hole 71, and one end is connected to the limiting member 6, and the other end faces the positioning rib 4 and abuts against the inner wall of the first through hole 71.

[0059] In this embodiment, the movable clamping plate 7 is disposed on the tool holder 1 and spans the first moving blade 31. The portion of the movable clamping plate 7 located on both sides of the first moving blade 31 is provided with a first through hole 71. The limiting member 6 includes a connecting part and a limiting part. One end of the connecting part passes through the first through hole 71 and is connected to the tool holder 1, and the other end is provided with a limiting part. The limiting part cooperates with the hole wall of the first through hole 71 to restrict the movable clamping plate 7 from moving away from the tool holder 1. At the same time, an movable gap is provided between the limiting part and the tool holder 1, so that the movable clamping plate 7 can move toward or away from the positioning rib 4. In addition, one end of the first return spring 5 in the first through hole 71 is connected to the connecting part, and the other end faces the positioning rib 4 and abuts against the inner wall of the first through hole 71. Under the action of external force, the movable clamping plate 7 can move away from the positioning rib 4 and place the integrated circuit at the positioning rib 4. At this time, when the external force is removed, the movable clamping plate 7 moves toward the positioning rib 4 under the action of the first return spring 5 and clamps the integrated circuit, improving the stability of the integrated circuit during cutting, thereby improving the cutting accuracy and effect.

[0060] In this embodiment, the movable clamping plate 7 is used to clamp the flat integrated circuit in cooperation with the positioning rib 4. Specifically, when cutting the flat integrated circuit, a pair of first moving blades 31 move in opposite directions on the blade holder 1 to form gaps with the positioning rib 4. At the same time, the movable clamping plate 7 is pushed to move away from the positioning rib 4, so that it forms a gap with the positioning rib 4. Then, the pins of the flat integrated circuit are placed in the gap and the gap. At this time, the external force is removed, and the movable clamping plate 7 moves towards the positioning rib 4 under the action of the first return spring 5, clamping the flat integrated circuit. The pair of first moving blades 31 move towards each other on the blade holder 1. The first moving blades 31 and the cutting blade 8 cooperate with the positioning rib 4 to cut the pins and connecting ribs of the flat integrated circuit at the same time.

[0061] In this preferred embodiment, the first through hole 71 is an elongated hole, and the extension line is the cutting direction of the first moving blade 31. The limiting member 6 is a screw, with the screw shank as the connecting part and the nut as the limiting part. However, it is not limited to this. The first through hole 71 can also be a round hole, a square hole, or a hole of other shapes. The limiting member 6 can also be a bolt, a rivet, or other limiting structure, as long as it meets the requirements.

[0062] In the optional technical solution of this embodiment, a second return spring 21, a locking member 22 and a driving assembly are also included. The driving assembly is used to drive the moving blades with opposite blades to move closer to each other. A second through hole 23 is provided on the moving blade. The second return spring 21 is disposed in the second through hole 23, and one end is connected to the blade holder 1 through the locking member 22. The other end faces the back of the moving blade and abuts against the inner wall of the second through hole 23.

[0063] In this embodiment, the first moving blade 31 has two second through holes 23, and a second return spring 21 is provided in each second through hole 23. One end of the second return spring 21 is fixed to the blade holder 1 by a locking member 22, and the other end faces the back of the first moving blade 31 and abuts against the inner wall of the second through hole 23. The first moving blade 31 moves toward the positioning rib 4 under the action of the driving component to achieve cutting. After the cutting is completed, the driving force of the driving component is removed, and the first moving blade 31 moves away from the positioning rib 4 under the action of the second return spring 21 to achieve self-reset of the first moving blade 31. The second return spring 21 cooperates with the driving component to realize the reciprocating motion of the second moving blade 32. The structure is simple and the driving is convenient.

[0064] In this embodiment, the drive assembly can simultaneously drive the opposing moving blades to move via two telescopic mechanisms. Extending the drive ends of the two telescopic mechanisms pushes the opposing moving blades to cut, while retracting them opens the opposing moving blades. The structure is simple and the drive is convenient.

[0065] In this preferred embodiment, the drive assembly includes a drive motor 24, a drive rod assembly 25, an eccentric wheel 26, and at least one pair of first transmission wheels 27 that are connected to it. Each first transmission wheel 27 is provided with an eccentric wheel 26 that rotates coaxially with it. The drive rod assembly 25 includes a first rod body 251 and a second rod body 252. The first rod body 251 is connected to the eccentric wheel 26, and the second rod body 252 is connected to the moving blade. The first rod body 251 and the second rod body 252 are movably connected. The drive motor 24 is used to drive the first transmission wheels 27 to rotate.

[0066] In this embodiment, each of the two first transmission wheels 27 is equipped with an eccentric wheel 26, and one of the two first transmission wheels 27 is connected to the drive motor 24, either directly to the output shaft of the drive motor 24 or indirectly through other transmission methods. Simultaneously, the first rod 251 and the second rod 252 are movably connected, so that when the eccentric wheel 26 drives the first rod 251, the second rod 252 can adjust its angle with the first rod 251, thereby enabling the second rod 252 to drive the moving blade. The structure is simple, and the driving effect is good and stable.

[0067] In the optional technical solution of this embodiment, a pair of opposing cutting blades 8 are also included. The cutting blades 8 are disposed on the first moving blade 31, and the cutting edges of the first moving blade 31 and the cutting blades 8 are perpendicular to each other. The cutting blades 8 are used to cut the pins of the integrated circuit while the first moving blade 31 cuts the connecting ribs of the integrated circuit. This enables the entire device to simultaneously cut the pins and connecting ribs of flat integrated circuits, improving cutting efficiency. Simultaneously, the driving assembly drives both the pair of first moving blades 31 and the pair of cutting blades 8 to cut, eliminating the need for two separate driving assemblies. This simplifies the overall structure, saves costs, and effectively utilizes the driving force, avoiding waste.

[0068] In the optional technical solution of this embodiment, an adjustment seat 9 is also provided on the first moving blade 31, and the tendon cutting blade 8 is connected to the adjustment seat 9; the adjustment seat 9 is provided with a first adjustment structure and a second adjustment structure, the positioning rib 4 is located between a pair of tendon cutting blades 8, the first adjustment structure is used to adjust the distance between the tendon cutting blade 8 and the positioning rib 4, and the second adjustment structure is used to adjust the cutting position of the tendon cutting blade 8.

[0069] In this embodiment, the cutting blade 8 is mounted on the first moving blade 31 via an adjusting seat 9, and the cutting blade 8 is linked to the first moving blade 31; that is, the cutting blade 8 is mounted on the first moving blade 31 via the adjusting seat 9 and moves synchronously with the first moving blade 31. The driving component only needs to drive the first moving blade 31 to move, which can realize the movement of the cutting blade 8. The structure has a higher integration and better movement effect. When cutting flat integrated circuits, where the flat integrated circuit has pins on the top and bottom sides and connecting ribs on the left and right sides, and the pins and connecting ribs are all connected to the outer rectangular frame, the cutting blade 8 moves in tandem with the blade of the first moving blade 31. The blades of blade 8 are perpendicular to each other, and the cutting blade 8 is located on the upper side of the movable clamping plate 7. When the flat integrated circuit is clamped on the positioning rib 4 by the movable clamping plate 7, the driving component drives the first moving blade 31 to cut the lower pins. At the same time, the cutting blade 8 cuts the connecting ribs on the left or right side, so that the pins and connecting ribs are cut at the same time, improving the cutting efficiency. After cutting, the flat integrated circuit is rotated 180° and re-clamped, and then the other pins and other connecting ribs are cut. In the entire process of cutting the flat integrated circuit, only one rotation is needed to cut all the pins and connecting ribs, improving the cutting efficiency.

[0070] In this embodiment, to adapt to cutting the connecting ribs of integrated circuits with different flat structures, the distance between the cutting blade 8 and the positioning rib 4 can be adjusted by the first adjustment structure on the adjustment seat 9, and the up, down, left, and right cutting position of the cutting blade 8 can be adjusted by the second adjustment structure. Preferably, the first adjustment structure includes a first adjustment hole provided on the adjustment seat 9, the cutting blade 8 is inserted into the first adjustment hole, and the first adjustment hole is provided with an adjustment range. The distance between the cutting blade 8 and the positioning rib 4 can be adjusted according to the requirements by adjusting the adjustment range. Specifically, the cutting blade 8 can slide within the adjustment range. After the range is adjusted, the positioning structure restricts the sliding of the cutting blade 8 within the adjustment range to ensure the stability of the cutting blade 8 during cutting. The positioning structure can... The positioning pin, positioning block, positioning rod, or positioning bolt can be used, as long as it meets the requirements. The second adjustment structure includes an adjusting element 92 and a second adjusting hole 91 opened on the adjusting seat 9. The adjusting element 92 passes through the second adjusting hole 91 to fix the adjusting seat 9 on the first moving blade 31. The second adjusting hole 91 is an elongated hole that extends in the direction of the cutting edge of the second moving blade 32. The adjusting element 92 can be a bolt or rivet, or other structures as long as they meet the requirements. By changing the position of the adjusting element 92 in the second adjusting hole 91, the position of the adjusting seat 9 is changed, thereby adjusting the left and right position of the tendon cutting blade 8. The second adjustment structure also includes a shim. By adding or removing the shim, the height of the adjusting seat 9 is adjusted, thereby adjusting the up and down position of the tendon cutting blade 8. The structure is simple, the adjustment is convenient, and the applicability of the tendon cutting blade 8 is improved.

[0071] In this embodiment, a pair of first transmission wheels 27 can be provided, and the tool holder 1 is located between the pair of first transmission wheels 27. The drive motor 24 drives the pair of first transmission wheels 27 to rotate, causing the eccentric wheel 26 on them to rotate, which in turn drives the drive rod assembly 25 on the eccentric wheel 26 to rotate, thereby enabling the drive rod assembly 25 to drive the first moving blade 31 to move. The drive rod assembly 25 can be connected to the first moving blade 31. In this case, the second return spring 21 and the locking member 22 can be omitted on the first moving blade 31. The drive rod assembly 25 moves the first moving blade 31 back and forth. Preferably, the drive rod assembly 25 is not connected to the first moving blade 31. During the movement of the drive rod assembly 25, it can abut against the first moving blade 31 to drive the first moving blade 31 to cut, and it can also reset the first moving blade 31 through the second return spring 21. This forms a reciprocating motion, which is simple in structure. The drive rod assembly 25 only drives the first moving blade 31 forward and does not drive it backward and is not connected to the first moving blade 31, which improves the driving safety. At the same time, each part is independent and convenient for maintenance.

[0072] In the optional technical solution of this embodiment, two pairs of second transmission wheels 28 are also included. Each pair of second transmission wheels 28 is connected in a transmission manner. Two pairs of first transmission wheels 27 are arranged opposite each other. The tool holder 1 is arranged between the two pairs of first transmission wheels 27. One of each pair of second transmission wheels 28 is connected to the output shaft of the drive motor 24, and the other is used to drive a pair of first transmission wheels 27. At least one pair of moving blades with opposite blades also includes a pair of second moving blades 32. The second moving blades 32 are used to cut the connecting ribs of the integrated circuit. The drive rod assembly 25 also includes two crossbeams 253. The first rods 251 corresponding to a pair of first transmission wheels 27 are all hinged to a crossbeam 253. A pair of second rods 252 are arranged on the crossbeam 253. The pair of first transmission wheels 27 drive the crossbeam 253 to translate through the pair of first rods 251 on the corresponding pair of eccentric wheels 26. At the same time, the pair of second rods 252 drive the first moving blades 31 and the second moving blades 32 respectively.

[0073] In this embodiment, a pair of first moving blades 31 and a pair of second moving blades 32 can be slidably connected to the blade holder 1 separately. That is, the pair of first moving blades 31 and the pair of second moving blades 32 are located at two different points on the blade holder 1, without interfering with each other. The driving component simultaneously drives the pair of first moving blades 31 and the pair of second moving blades 32 to cut. The pair of first moving blades 31 is used solely for cutting leads, and the pair of second moving blades 32 is used solely for cutting connecting ribs. Alternatively, two blade holders 1 can be provided, with the pair of first moving blades 31 and the pair of second moving blades 32 slidably connected to two different blade holders 1. This structure is simple, easy to manufacture, and the cutting of leads and connecting ribs is performed independently without interference, improving cutting effect and accuracy. When the pair of first moving blades 31 and the pair of second moving blades 32 are respectively set on two different blade holders 1, the arrangement of the second moving blades 32 is the same as that of the first moving blades 31, and the driving component simultaneously drives the movement of both the first moving blades 31 and the second moving blades 32.

[0074] When a pair of first moving blades 31 and a pair of second moving blades 32 are respectively mounted on two tool holders 1, two pairs of second transmission wheels 28 are also included. Each pair of second transmission wheels 28 is connected in transmission. Two pairs of first transmission wheels 27 are arranged opposite each other. The tool holder 1 is located between the two pairs of first transmission wheels 27. One of each pair of second transmission wheels 28 is connected to the output shaft of the drive motor 24, and the other is used to drive a pair of first transmission wheels 27. At this time, the drive rod assembly 25 includes a first rod body 251, a second rod body 252 and two crossbeams 253. The first rod body 251 is mounted on the eccentric wheel 26. The eccentric wheel 26 is mounted on each pair of first transmission wheels 27. The first rod body 251 on the two eccentric wheels 26 is hinged to a crossbeam 253. The crossbeam 253 is provided with a second rod body 252 for driving the moving blades. Specifically, the crossbeam 253 is provided with two second rod bodies 252, which are used to drive the first moving blade 31 and the second moving blade 32 respectively. The overall drive is stable and the drive effect is improved.

[0075] In this embodiment, the pair of first drive wheels 27 can be driven by a belt or a chain, and the pair of second drive wheels 28 can be driven by a belt or a chain.

[0076] In the optional technical solution of this embodiment, the tool holder 1 includes a base 11, a first limiting wedge 12 and a second limiting wedge 13. A sliding groove is provided on the base 11, and the moving tool is slidably connected to the sliding groove. The first limiting wedge 12 and the second limiting wedge 13 are both disposed in the sliding groove and are located on both sides of the moving tool in the sliding direction in the sliding groove, which are used to restrict the moving tool in the sliding groove from moving to the side away from the base 11. A waste discharge hole 14 is provided at the bottom of the sliding groove, and the waste discharge hole 14 is located between the moving tools with opposite blades.

[0077] In this embodiment, the base 11 has a through groove at both ends. A pair of first moving blades 31 are disposed in the groove. The positioning ribs 4 are connected to the two side walls of the groove for easy installation and disassembly. The first limiting wedge 12 and the second limiting wedge 13 are disposed in the groove and are located on the side walls on both sides respectively. The first moving blade 31 is disposed between the first limiting wedge 12 and the second limiting wedge 13. The cross-section of the first moving blade 31 is trapezoidal and has a first inclined surface on both sides. The first limiting wedge 12 and the second limiting wedge 13 both have a second inclined surface that cooperates with the first inclined surface. The cooperation of the first inclined surface and the second inclined surface can restrict the movement of the first moving blade 31 away from the base 11, while facilitating the sliding of the first moving blade 31 back and forth between the first limiting wedge 12 and the second limiting wedge 13. The structure is simple and improves the sliding effect while limiting movement.

[0078] It should be noted that when a pair of first moving blades 31 and a pair of second moving blades 32 are respectively set on two tool holders 1, the two tool holders 1 have the same structure, which will not be described in detail here.

[0079] It should be noted that, since the strength of the connecting rib and the pin is different, and the strength of the connecting rib is greater than that of the pin, multiple pins need to be cut at the same time when cutting the pin, while only one connecting rib needs to be cut when cutting the connecting rib, the first moving blade 31 is flat and wide to facilitate cutting multiple pins at the same time. The rib cutting blade 8 and the second moving blade 32 are sharper and narrower to facilitate cutting the connecting rib and save materials.

[0080] This embodiment provides a cutting method for cutting dual in-line package (DIP) integrated circuits. Using the aforementioned integrated circuit cutting and forming equipment, the cutting method includes the following steps: moving a pair of first moving blades 31 in opposite directions on a blade holder 1 to form gaps with positioning ribs 4; placing the DIP integrated circuit at the corresponding position on the positioning ribs 4 according to the pin length of the DIP integrated circuit, so that the pins on both sides of the DIP integrated circuit are located within the two gaps; and moving the pair of first moving blades 31 in opposite directions on the blade holder 1 to cooperate with the positioning ribs 4 while simultaneously cutting the pins on both sides of the DIP integrated circuit. In this integrated circuit cutting and forming equipment, when a movable clamping plate 7 is installed, the cutting method can be as follows: a pair of first moving blades 31 move in opposite directions on the blade holder 1, forming gaps between themselves and the positioning ribs 4. This pushes the movable clamping plate 7 away from the positioning ribs 4, creating a slit between it and the positioning ribs 4. The dual-in-line package (DIP) integrated circuit is then placed on the corresponding position of the positioning ribs 4, so that the pins on both sides of the DIP integrated circuit are located within the two slits and two gaps, respectively. At this point, the external force is removed, and the movable clamping plate 7 moves towards the positioning ribs 4 under the action of the first return spring 5, clamping the pins on both sides of the DIP integrated circuit. The pair of first moving blades 31 then move towards each other on the blade holder 1, cooperating with the positioning ribs 4 to cut the pins on both sides of the DIP integrated circuit. This cutting method is convenient, stable, and highly applicable.

[0081] This embodiment provides another cutting method for cutting flat integrated circuits. Using the aforementioned integrated circuit cutting and forming equipment, the cutting method includes the following steps: a pair of first moving blades 31 move in opposite directions on the blade holder 1, forming gaps between themselves and the positioning ribs 4; the pins of the flat integrated circuit are placed within these gaps; the flat integrated circuit is fixed between the movable clamp 7 and the positioning ribs 4 using a movable clamp 7; the pair of first moving blades 31 move towards each other on the blade holder 1, with both the first moving blades 31 and the cutting blade 8 cooperating with the positioning ribs 4 to simultaneously cut the pins and connecting ribs of the flat integrated circuit. It should be noted that, depending on the requirements, the pair of first moving blades 31 can move in opposite directions on the blade holder 1, forming two gaps between themselves and the positioning ribs 4. Flat integrated circuits can be placed in both gaps, allowing for simultaneous cutting of two flat integrated circuits, thus improving cutting efficiency. Alternatively, the flat integrated circuit can be placed in only one of the gaps.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
