Description

Technical Field

[0001] This utility model relates to the field of integrated circuit processing equipment technology, specifically to an integrated circuit pin secondary processing device. Background Technology

[0002] In the field of modern electronics manufacturing, integrated circuits are core components, and the state of their pins plays a decisive role in the performance and quality of electronic products. As a key bridge connecting and communicating between the internal circuits and external circuits of a chip, the pins of an integrated circuit are the foundation for signal transmission and circuit connection. Their performance directly affects the stability, reliability, and signal transmission accuracy of the entire circuit system. In the integrated circuit manufacturing process, the pins need to go through multiple complex steps, and each step may introduce factors that affect the pin quality. Existing pin secondary processing technology lacks flexibility and precision in dealing with complex problems such as pin deformation and dimensional deviations, making it difficult to meet the increasingly stringent integrated circuit manufacturing standards.

[0003] To address the aforementioned deficiencies, the existing technology (Chinese Patent No. CN118875180B, published on March 18, 2025) provides a secondary forming processing device for integrated circuit pins. While the integrated circuit workpiece slides on the loading platform, it simultaneously compresses the extrusion airbag. At this time, the gas inside the extrusion airbag is transported to the interior of the air storage frame through an air supply pipe and then ejected outwards through an air blowing pipe located inside the air storage frame. This further cleans the sliding integrated circuit workpiece, reducing the impact of dust on subsequent impact operations.

[0004] The above solution involves moving the integrated circuit to compress the airbag, thereby cleaning the pins. However, the angle and position of the air blowing pipe are fixed during cleaning, and air blowing is only performed after the integrated circuit moves and is compressed. This has a delay and makes it difficult to clean the dust on the integrated circuit pins completely in a timely manner. Utility Model Content

[0005] The purpose of this utility model is to provide a secondary processing device for integrated circuit pins, so as to solve the problem of existing secondary processing devices for integrated circuit pins mentioned in the background art. In the process of use, the airbag is squeezed by moving the integrated circuit to clean the pins. The angle and position of the air blowing pipe are fixed during cleaning, and the air blowing is performed only after the movement and squeezing. This has a delay and is not convenient for timely and complete cleaning of the dust on the integrated circuit pins.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a secondary processing device for integrated circuit pins, comprising a worktable, wherein a fixed frame is installed in the middle of the top surface of the worktable, and an extrusion molding plate is connected to the top inner side of the fixed frame via an electric push rod;

[0007] The workbench is symmetrically slidably connected to a contact plate for positioning integrated circuits in the middle, and rollers are evenly spaced on the sides of the contact plate.

[0008] The fixed frame has symmetrical sliding grooves on its left and right sides, and a slide frame is slidably connected in the sliding groove. A dust suction pipe is hinged to the outside of the slide frame. A drive assembly for moving the dust suction pipe to suction dust is provided inside the fixed frame and inside the workbench.

[0009] Furthermore, a motor is installed in the middle of the inner side of the workbench, and a disc is connected to the outer side of the motor output end through a first ratchet assembly. The disc is rotatably connected to the middle of the inner side of the workbench.

[0010] Furthermore, the top of the disc is symmetrically provided with arc-shaped guide grooves, and a cylinder is slidably connected in the guide grooves. The middle part of the cylinder is slidably connected in a limiting groove. The limiting grooves are symmetrically and continuously provided in the middle top surface of the worktable, and the limiting grooves are designed as straight lines.

[0011] Furthermore, the cylinder forms a linear opening and closing sliding structure through guide grooves and limiting grooves, and a contact plate is fixed at the top of the cylinder. The contact plate positions, clamps, and releases the integrated circuit through opening and closing sliding.

[0012] Furthermore, the drive assembly includes a rotating seat symmetrically rotatably connected to the left and right sides inside the worktable. The outer side of the middle part of the screw is connected to the rotating seat through a second ratchet assembly. The second ratchet assembly rotates in the opposite direction to the first ratchet assembly. The bottom of the screw is connected to the output end of the motor through a sprocket mechanism.

[0013] Furthermore, the top of the screw is rotatably connected to the slide groove, and the outer side of the screw is threadedly connected to a slide frame, which drives the suction pipe to form an up-and-down moving structure.

[0014] Furthermore, a spring is slidably connected to the outer side of the carriage, and a movable block is connected to it. The movable block is made of magnetic material, and the outer side of the movable block intermittently overlaps with the magnetic block. The magnetic blocks are installed at equal intervals on the left side of the fixed frame. The movable block, the spring, and the magnetic block form a horizontal sliding structure.

[0015] Furthermore, a pull rope is fixed to the outside of the movable block, and the outer end of the pull rope is connected to the hinge of the vacuum tube. A torsion spring is installed at the hinge of the vacuum tube, and the vacuum tube forms a swinging vacuuming structure through the torsion spring and the pull rope.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This integrated circuit pin secondary processing device, through a collaborative working system of precise positioning, forming processing, and dynamic dust collection, relies on the orderly cooperation of the worktable, positioning component, extrusion forming component, and driving dust collection component to realize the automated secondary processing of integrated circuit pins and real-time cleaning of dust during the processing. It not only solves the processing deviation problem caused by insufficient positioning accuracy of traditional devices, but also overcomes the defect of incomplete cleaning by fixed dust collection structure.

[0018] 1. Furthermore, the motor output end drives the disc to rotate clockwise through the first ratchet assembly. The symmetrical arc-shaped guide grooves on the top of the disc rotate synchronously with the gear. The cylinders slidably connected in the guide grooves are constrained by the limiting grooves and cannot move in a circle with the guide grooves. They can only slide in opposite directions along the axial direction of the limiting grooves. The contact plates fixed on the top of the cylinders move synchronously until the two contact plates on both sides are in close contact with the integrated circuit housing.

[0019] 2. Furthermore, the rollers on the side of the contact plate are in contact with the surface of the housing. This reduces friction damage between the housing and the contact plate by utilizing the rolling characteristics of the rollers. It also allows for slight centering correction of the integrated circuit during clamping, achieving high-precision clamping and positioning. This ensures that the pin positions do not shift during subsequent processing. After positioning is completed, the extrusion molding assembly is activated to perform secondary processing and molding operations on the integrated circuit pins.

[0020] 3. Furthermore, when the motor reverses, its output end drives the screw to rotate through the sprocket mechanism. The screw is threadedly connected to the carriage, and the carriage is limited by the slide groove. Therefore, when the screw rotates, it will drive the carriage to move vertically up and down along the slide groove, thereby driving the dust suction pipe to cover the processing area at different heights.

[0021] 4. Furthermore, as the slide moves up and down, the moving block inside the carriage will intermittently overlap with the magnetic blocks installed at equal intervals on the left side of the fixed frame. With the help of the torsion spring, the suction pipe will swing while moving up and down, and the suction pipe can fully cover the dust in the processing area. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: Please refer to Figure 1 - Figure 2 The present invention provides the following technical solution: a secondary processing device for integrated circuit pins, including a workbench 1, a fixed frame 2 installed in the middle of the top surface of the workbench 1, an extrusion molding plate 3 connected to the top inner side of the fixed frame 2 via an electric push rod, a contact plate 10 for positioning integrated circuits symmetrically slidably connected in the middle of the workbench 1, rollers equally spaced on the side of the contact plate 10, a sliding groove 15 symmetrically opened on the left and right sides of the fixed frame 2, a slide 16 slidably connected in the sliding groove 15, a suction pipe 17 hinged to the outer side of the slide 16, and a drive assembly for driving the suction pipe 17 to move and suction dust inside the fixed frame 2 and inside the workbench 1.

[0031] Please refer to Figure 1 - Figure 2 As shown, during use, the workbench 1 is placed at an angle, and the integrated circuit to be processed is placed on the workbench 1. The contact plates 10 on both sides of the workbench 1 can clamp and fix the integrated circuit. Then, the pins of the integrated circuit are subjected to secondary forming and extrusion by the extrusion molding plate 3 on the fixing frame 2. During the processing, the slide 16 in the slide groove 15 on both sides of the fixing frame 2 drives the dust suction pipe 17 to move up and down and swing at the same time through the drive component, thereby thoroughly cleaning the dust that falls on the integrated circuit and avoiding affecting the subsequent processing quality.

[0032] Example 2:

[0033] Based on Embodiment 1, a precise clamping and positioning mechanism is also disclosed. Please refer to [link / reference]. Figure 1 - Figure 4 As shown, its specific structure is as follows: A motor 4 is installed in the middle of the inner side of the workbench 1. The outer side of the output end of the motor 4 is connected to a disc 6 through a first ratchet assembly 5. The disc 6 is rotatably connected to the middle of the inner side of the workbench 1. An arc-shaped guide groove 7 is symmetrically opened on the top of the disc 6. A cylinder 8 is slidably connected in the guide groove 7. The middle part of the cylinder 8 is slidably connected in a limiting groove 9. The limiting groove 9 is symmetrically opened through the top surface of the middle part of the workbench 1. The limiting groove 9 is set as a straight structure. The cylinder 8 forms a straight opening and closing sliding structure through the guide groove 7 and the limiting groove 9. A contact plate 10 is fixed on the top of the cylinder 8. The contact plate 10 positions, clamps, and releases the integrated circuit through opening and closing sliding.

[0034] refer to Figure 1 - Figure 4 As shown, during operation, after the equipment is started, the positioning component first completes the precise clamping and positioning of the integrated circuit, providing a stable foundation for subsequent pin processing. The operator places the integrated circuit to be processed on the center of the top surface of the workbench 1 and starts the motor 4. Its output end drives the disc 6 to rotate clockwise through the first ratchet assembly 5. The symmetrical arc-shaped guide grooves 7 on the top of the disc 6 rotate synchronously with the gear. The cylinder 8, which is slidably connected in the guide groove 7, is constrained by the limiting groove 9 and cannot move in a circular motion with the guide groove 7. It can only slide towards each other along the axial direction of the limiting groove 9. The contact plate 10 fixed on the top of the cylinder 8 moves synchronously until the two contact plates 10 on both sides are in close contact with the integrated circuit shell. At this time, the roller 11 on the side of the contact plate 10 is in contact with the shell surface, which means that... The rolling characteristics of the roller 11 reduce frictional damage between the housing and the contact plate 10, and also allow for slight centering correction of the integrated circuit during clamping, achieving high-precision clamping and positioning. This ensures that the pin position does not shift during subsequent processing. After positioning, the extrusion molding assembly is activated to perform secondary processing and molding on the integrated circuit pin. The electric push rod on the top inner side of the fixing frame 2 extends, pushing the extrusion molding plate 3 vertically downward until the processing surface of the extrusion molding plate 3 contacts the integrated circuit pin. According to the processing requirements of the pin, the extrusion molding plate 3 applies a preset pressure to press the pin to the standard size and shape. During the processing, the contact plate 10 always maintains the clamping state of the integrated circuit to avoid workpiece displacement due to extrusion force and ensure processing accuracy.

[0035] Example 3:

[0036] Based on Embodiment 2, a dynamic dust collection mechanism is also disclosed; please refer to [reference needed]. Figure 1 - Figure 2 and Figure 4 - Figure 6As shown, its specific structure is as follows: The drive assembly includes a rotating seat 12 symmetrically rotatably connected to the left and right sides inside the workbench 1. A screw 14 is connected through the middle of the rotating seat 12. The outer side of the middle part of the screw 14 is connected to the rotating seat 12 through a second ratchet assembly 13. The second ratchet assembly 13 rotates in the opposite direction to the first ratchet assembly 5. The bottom of the screw 14 is connected to the output end of the motor 4 through a sprocket mechanism. The top of the screw 14 is rotatably connected to a slide groove 15. A slide 16 is threadedly connected to the outer side of the screw 14. The slide 16 drives the suction pipe 17. The slide 16 forms a vertically movable structure. A spring 19 is slidably connected to the outer side of the slide 16, and a movable block 18 is connected to it. The movable block 18 is made of magnetic material. The outer side of the movable block 18 intermittently overlaps with the magnetic block 22. The magnetic blocks 22 are installed at equal intervals on the left side of the fixed frame 2. The movable block 18, the spring 19 and the magnetic block 22 form a horizontally sliding structure. A pull rope 21 is fixed to the outside of the movable block 18. The outer end of the pull rope 21 is connected to the hinge of the suction pipe 17. A torsion spring 20 is installed at the hinge of the suction pipe 17. The suction pipe 17 forms a swing suction structure through the torsion spring 20 and the pull rope 21.

[0037] refer to Figure 1 - Figure 2 and Figure 4 - Figure 6 As shown, during use, after positioning, the drive assembly drives the suction pipe 17 to achieve dynamic suction by moving up and down and swinging left and right, thoroughly cleaning the dust generated during processing. The motor 4 reverses, and its output end drives the screw 14 to rotate through the sprocket mechanism. The screw 14 is threadedly connected to the slide 16, and the slide 16 is limited by the slide groove 15. Therefore, when the screw 14 rotates, it will drive the slide 16 to move vertically up and down along the slide groove 15, thereby driving the suction pipe 17 to cover processing areas at different heights, such as the top and sides of the pins. On the other hand, the moving block 18 inside the slide 16 will intermittently move as the slide 16 moves up and down. The magnetic blocks 22, which are installed at equal intervals on the left side of the mounting bracket 2, overlap with the magnetic blocks 22. When the moving block 18 approaches the magnetic blocks 22, it is attracted by the magnetic force and slides towards the magnetic blocks 22 against the elastic force of the spring 19. The suction tube 17 is pulled around the hinge by the pull rope 21, and the torsion spring 20 is twisted and stores energy. When the moving block 18 moves away from the magnetic blocks 22, the spring 19 pushes the moving block 18 back to its original position. The suction tube 17 rotates in the opposite direction and resets under the action of the torsion spring 20. This cycle continues. The suction tube 17 swings while moving up and down. The suction tube 17 can fully cover the dust in the processing area and avoid dust residue from affecting the electrical performance of the integrated circuit pins.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
