Description

Technical Field

[0001] This invention relates to the field of chip pin reshaping and correction technology, specifically to a jig for chip pin reshaping and correction. Background Technology

[0002] Chip pin shaping and correction fixtures are key auxiliary equipment in the semiconductor packaging and electronic manufacturing fields. They are mainly used to solve deformation problems such as pin bending, spacing misalignment, and poor coplanarity that occur during chip production, transportation, or storage. They are widely compatible with various chip package types such as QFP, LQFP, SOP, TSSOP, and DIP, and can meet the needs of different scenarios such as laboratory research and development, small-batch trial production, and mass production. The fixture adopts a modular design, and its core structure consists of four parts: a positioning and clamping module, a shaping execution module, a drive adjustment module, and a protection and detection module. During operation, it achieves precise pin correction through a closed-loop process of "feeding positioning, spacing adjustment, top and bottom leveling, multi-face shaping, and unloading verification".

[0003] Chinese patent CN222036629U discloses a chip pin shaping device, including a base plate, a mounting plate fixedly connected to the base plate, a cylinder fixedly connected to the mounting plate, a horizontal plate I fixedly connected to the output end of the cylinder, a round rod slidably connected to the horizontal plate I, and a horizontal plate II fixedly connected to one end of the round rod. The cylinder can be activated to first fix the chip using a fixing block, and then continue to push the pressure block to shape the chip pins, ensuring stability during shaping. Then, by rotating the threaded rod I, two sets of pressure blocks can slide within a groove I, adjusting the distance between the two sets of pressure blocks to shape chips of different sizes.

[0004] While this technical solution can shape the chip pins and perform shaping work on chips of different sizes, the unloading process still relies on manual operation after the pin shaping process is completed. During manual unloading, it is difficult to accurately control the operating force and the pick-and-place angle, which can easily cause the chip and the positioning structure of the fixture to jam. This will not only interrupt the processing flow and reduce the overall production efficiency, but may also cause secondary deformation of the pins due to jamming, affecting the shaping accuracy and thus increasing the product defect rate.

[0006] This invention provides a fixture for shaping and correcting chip pins. It has the following beneficial effects: 1. The chip pin shaping and correction fixture, after the drive unit is turned on, its output end drives the connecting shaft to move upward. The connecting shaft synchronously drives the ejector block to move upward, ejecting the shaped chip from the shaping cavity. There is no need for manual insertion into the cavity to grab the chip, avoiding secondary deformation caused by hand touching the pin. At the same time, it improves the convenience and efficiency of the unloading operation and reduces the chip damage and scrap rate.

[0007] 2. The jig for shaping and correcting chip pins, after the ejector block completes the chip ejection and unloading action, the output end of the drive unit drives the connecting shaft to reset downward. During this process, the connecting shaft drives the suction component to start operation through the mounting bracket, sucking in and collecting the impurities raised during the air blowing cleaning process, realizing closed-loop cleaning of blowing and collection, avoiding the flying and diffusion of impurities, and facilitating the unified treatment of impurities.

[0008] 3. The chip pin shaping and correction fixture, after the ejector block pushes the chip out of the shaping cavity, the airflow from the exhaust pipe obliquely blows the shaping comb teeth on the detachable shaping plate. By arranging the exhaust pipe in a ring on the detachable shaping plate, the airflow covers the support surface in a swirling shape, carrying away residual oxide scale and dust. The oblique blowing design of the comb teeth can specifically remove pin oxide debris stuck in the teeth, avoiding the problem of subsequent chip pin spacing deviation caused by debris clogging the comb teeth from the root, ensuring shaping accuracy. The swirling blowing formed by the ring exhaust pipe can fully cover and remove surface dust and oxide scale, avoiding the adhesion of impurities that affect the positioning stability of subsequent chips.

[0009] 4. The jig for shaping and correcting chip pins has an additional guide plate on the inside of the suction cylinder. Impurities are guided into the suction cylinder storage area by the guide plate, which prevents impurities that are blown off from drifting and remaining on the surface of the detachable shaping plate, and prevents impurities from adhering to the comb teeth or positioning grooves again, thus ensuring the cleanliness of the cavity.

[0010] 5. The jig for shaping and correcting the chip pins, during the upward movement of the pusher plate, simultaneously pushes the gas and stored impurities in the suction cylinder to be discharged through the one-way discharge valve. This can avoid the problem of negative pressure attenuation and decreased suction efficiency caused by the accumulation of impurities in the suction cylinder, extend the maintenance cycle of the suction mechanism, and reduce the frequency of manual cleaning.

An ejection block 73 is fixedly connected to the top of the connecting shaft 72. An auxiliary mechanism 74 is sleeved on the connecting shaft 72. After the drive unit 71 is turned on, its output end drives the connecting shaft 72 to move upward. The connecting shaft 72 synchronously drives the ejector block 73 to move upward, ejecting the shaped chip from the shaping cavity. It eliminates the need for manual insertion into the mold cavity to pick up chips, avoiding secondary deformation caused by hand touching the pins, while improving the convenience and efficiency of the unloading operation and reducing the chip damage and scrap rate; Please see Figure 7 The auxiliary mechanism 74 includes a guide assembly 741, mounting holes 742 and two mounting brackets 743. The two mounting brackets 743 are mounted on the connecting shaft 72 by fasteners. An air blowing assembly 744 and an air suction assembly 746 are fixedly connected to both sides of the mounting brackets 743 respectively. The tops of the air blowing assembly 744 and the air suction assembly 746 are fixedly connected to the inside of the guide assembly 741. The side of the guide assembly 741 is fixedly connected to the inside of the detachable shaping plate 8. The mounting holes 742 are evenly opened on the top of the detachable shaping plate 8. As the connecting shaft 72 moves upward with the output end of the drive component 71, it synchronously drives the auxiliary mechanism 74 to operate in conjunction, and starts the cleaning operation around the forming cavity at the same time as the chip is unloaded; Two mounting brackets 743 are fixedly mounted on the connecting shaft 72 by fasteners. When the connecting shaft 72 moves upward, the air blowing assembly 744 moves synchronously through the mounting brackets 743. The gas output by the air blowing assembly 744 is guided by the guide assembly 741 and sprayed out in a direction through the preset mounting hole 742 to blow the cavity area after the shaping operation is completed. After the ejector block 73 completes the chip ejection and unloading action, the output end of the drive component 71 drives the connecting shaft 72 to reset downward. During this process, the connecting shaft 72 synchronously drives the suction component 746 to start operation through the mounting bracket 743, sucking in and collecting the impurities raised during the air blowing cleaning process. Please see Figures 8-9 The guide assembly 741 includes a guide ring 1 7411 and a guide ring 2 7412. The side of the guide ring 1 7411 is fixedly connected to the inner side of the detachable shaping plate 8. The side of the guide ring 1 7411 is evenly provided with an air inlet pipe 7413, and the side of the air inlet pipe 7413 is fixedly connected to the inner side of the guide ring 1 7411. The side of the guide ring 2 7412 is evenly provided with an air outlet pipe 7414, and the side of the air outlet pipe 7414 is fixedly connected to the inner side of the guide ring 2 7412.

The bottom of the connecting rod 7441 is fixedly connected to the side of the mounting bracket 743. A push plate 7444 is fixedly connected to the top of the connecting rod 7441. The side of the push plate 7444 is slidably connected to the inner side of the air outlet 7442. A one-way air inlet valve 7443 is fixedly connected to the side of the air outlet 7442. When the output end of the drive component 71 drives the connecting shaft 72 to move upward, the connecting shaft 72 drives the connecting rod 7441 to move upward through the mounting bracket 743, thereby driving the push plate 7444 to slide upward inside the air outlet 7442. With the one-way air inlet valve 7443 set on the side of the air outlet 7442, only external gas is allowed to enter the air outlet 7442 in one direction. During the upward movement of the push plate 7444, the gas in the air outlet 7442 can be compressed. The compressed gas is guided through the connecting cylinder 7415 to the guide ring 7412, and finally sprayed out in a direction through the air outlet pipe 7414. After the ejector block 73 ejects the chip from the shaping cavity, the airflow from the exhaust pipe 7414 obliquely sweeps the shaping comb teeth on the detachable shaping plate 8. By arranging air pipes 7414 in a ring on the detachable shaping plate 8, the airflow is made to cover the support surface in a swirling shape, carrying away the residual oxide scale and dust. The oblique blowing design of the comb teeth can specifically remove the pin oxide debris stuck in the gaps, thus avoiding the problem of subsequent chip pin spacing deviation caused by debris clogging the comb teeth and ensuring shaping accuracy. The swirling airflow formed by the annular exhaust pipe 7414 can fully cover and remove surface dust and oxide scale, preventing impurities from adhering and affecting the positioning stability of subsequent chips. Please see Figure 11 The suction assembly 746 includes a suction cylinder 7461 and a connecting rod 7462. The top of the inner cavity of the suction cylinder 7461 is fixedly connected to the side of the guide ring 7411. The side of the connecting rod 7462 is slidably connected to the bottom of the inner cavity of the suction cylinder 7461. The side of the suction cylinder 7461 is fixedly connected to the inner side of the detachable shaping plate 8. The bottom of the connecting rod 7462 is fixedly connected to the side of the mounting bracket 743 away from the connecting rod 7441. A push plate 7463 is fixedly connected to the top of the connecting rod 7462. The side of the push plate 7463 is slidably connected to the inner side of the suction cylinder 7461. Next, a telescopic rod 7464 is fixedly connected to the middle of the top of the push plate 7463. A circular plate 7466 is fixedly connected to the top of the telescopic rod 7464. A connecting spring 7465 is sleeved on the telescopic rod 7464. The top of the connecting spring 7465 is fixedly connected to the bottom of the circular plate 7466. The bottom of the connecting spring 7465 is fixedly connected to the top of the push plate 7463. A one-way discharge valve 7467 is fixedly connected to the side of the suction cylinder 7461. A guide plate 7468 is fixedly connected to the inner side of the suction cylinder 7461. A discharge hole 7469 is opened in the middle of the guide plate 7468. After the chip ejection and unloading are completed, the drive unit 71 is activated so that its output end drives the connecting shaft 72 to move downward. The connecting shaft 72 synchronously drives the mounting frame 743 to move downward. The mounting frame 743 drives the push plate 7463 to slide downward in the air suction cylinder 7461 through the second connecting rod 7462, thus starting the air suction and collection operation. The impurities blown off by the comb teeth of the detachable shaping plate 8 are sucked into the inner cavity of the guide ring 7411 through the air inlet pipe 7413. As the connecting shaft 72 continues to move downward, the push plate 7463 remains in a downward state in the air intake cylinder 7461, continuously maintaining the negative pressure of air intake. The impurities then enter the air intake cylinder 7461 through the slot 7416 opened in the guide ring 7411. A guide plate 7468 is added to the inner side of the suction cylinder 7461, and impurities are guided into the storage area of ​​the suction cylinder 7461 by the guide plate 7468. To prevent impurities that have fallen off from being blown away from scattering and remaining on the surface of the detachable shaping plate 8, and to prevent impurities from adhering to the comb teeth or positioning grooves again, thus ensuring the cleanliness of the cavity; When chip unloading is performed, the output end of the drive component 71 drives the connecting shaft 72 to move upward. The connecting shaft 72 drives the second connecting rod 7462 to move upward synchronously through the mounting bracket 743. The second connecting rod 7462 drives the second push plate 7463 to slide upward inside the suction cylinder 7461. During the upward movement of the push plate 7463, the telescopic rod 7464 drives the circular plate 7466 to move upward synchronously until the circular plate 7466 precisely abuts against the material drop hole 7469 at the bottom of the guide plate 7468, blocking the impurity backflow channel. As the push plate 7463 continues to move upward, the telescopic rod 7464 is compressed and contracts, and the connecting spring 7465 sleeved on the outside of the telescopic rod 7464 is compressed synchronously. During the upward movement of push plate 7463, the gas and some impurities stored in suction cylinder 7461 are simultaneously pushed out through one-way discharge valve 7467. To ensure timely removal of impurities from the suction cylinder 7461 and prevent the accumulation of impurities from reducing suction efficiency; Specific workflow: Replace the corresponding detachable shaping plate 8 and detachable pin clamping block 9 according to the specifications of the component to be processed; Place the electronic component to be shaped into the detachable shaping plate 8 to complete the positioning and fixation of the component; Operate the reversing valve switch 4 to start the pressing component 3. The connecting component 6 drives the detachable pin pressing block 9 to move downward, pressing the pin of the component into the preset shape of the forming cavity, thus completing the bending and shaping of the pin. After the shaping is completed, operate the reversing valve switch 4 again to start the ejector component 7, and eject the processed component from the shaping cavity to facilitate the operator to remove the workpiece; After the drive unit 71 is turned on, its output end drives the connecting shaft 72 to move upward. The connecting shaft 72 synchronously drives the ejector block 73 to move upward, ejecting the shaped chip from the shaping cavity.

When the connecting shaft 72 moves upward, the air blowing assembly 744 moves synchronously through the mounting brackets 743. The gas output by the air blowing assembly 744 is guided by the guide assembly 741 and sprayed out in a direction through the preset mounting hole 742 to blow the cavity area after the shaping operation is completed. It can promptly remove pin-shaped debris, dust, and other impurities adhering to the cavity surface, preventing impurity residue from affecting the subsequent chip positioning and shaping effect, and ensuring the consistency of batch shaping operations; After the ejector block 73 completes the chip ejection and unloading action, the output end of the drive component 71 drives the connecting shaft 72 to reset downward. During this process, the connecting shaft 72 synchronously drives the suction component 746 to start operation through the mounting bracket 743, sucking in and collecting the impurities raised during the air blowing cleaning process. It achieves closed-loop cleaning of blowing and collecting, avoiding the spread of impurities, and facilitating the unified treatment of impurities; Significantly shorten process intervals, improve the automation and continuity of the forming fixture, reduce manual intervention, balance material unloading convenience and cavity cleanliness, and ensure the yield and stability of the chip forming process. When the output end of the drive component 71 drives the connecting shaft 72 to move upward, the connecting shaft 72 drives the connecting rod 7441 to move upward through the mounting bracket 743, thereby driving the push plate 7444 to slide upward inside the air outlet 7442. With the one-way air inlet valve 7443 set on the side of the air outlet 7442, only external gas is allowed to enter the air outlet 7442 in one direction. During the upward movement of the push plate 7444, the gas in the air outlet 7442 can be compressed. The compressed gas is guided through the connecting cylinder 7415 to the guide ring 7412, and finally sprayed out in a direction through the air outlet pipe 7414. After the ejector block 73 ejects the chip from the shaping cavity, the airflow from the exhaust pipe 7414 obliquely sweeps the shaping comb teeth on the detachable shaping plate 8. By arranging air pipes 7414 in a ring on the detachable shaping plate 8, the airflow is made to cover the support surface in a swirling shape, carrying away the residual oxide scale and dust. The oblique blowing design of the comb teeth can specifically remove the pin oxide debris stuck in the gaps, thus avoiding the problem of subsequent chip pin spacing deviation caused by debris clogging the comb teeth and ensuring shaping accuracy. The swirling airflow formed by the annular exhaust pipe 7414 can fully cover and remove surface dust and oxide scale, preventing impurities from adhering and affecting the positioning stability of subsequent chips. After the chip ejection and unloading are completed, the drive unit 71 is activated so that its output end drives the connecting shaft 72 to move downward. The connecting shaft 72 synchronously drives the mounting frame 743 to move downward. The mounting frame 743 drives the push plate 7463 to slide downward in the air suction cylinder 7461 through the second connecting rod 7462, thus starting the air suction and collection operation. The impurities blown off by the comb teeth of the detachable shaping plate 8 are sucked into the inner cavity of the guide ring 7411 through the air inlet pipe 7413. As the connecting shaft 72 continues to move downward, the push plate 7463 remains in a downward state in the air intake cylinder 7461, continuously maintaining the negative pressure of air intake. The impurities then enter the air intake cylinder 7461 through the slot 7416 opened in the guide ring 7411. A guide plate 7468 is added to the inner side of the suction cylinder 7461, and impurities are guided into the storage area of ​​the suction cylinder 7461 by the guide plate 7468. To prevent impurities that have fallen off from being blown away from scattering and remaining on the surface of the detachable shaping plate 8, and to prevent impurities from adhering to the comb teeth or positioning grooves again, thus ensuring the cleanliness of the cavity; When chip unloading is performed, the output end of the drive component 71 drives the connecting shaft 72 to move upward. The connecting shaft 72 drives the second connecting rod 7462 to move upward synchronously through the mounting bracket 743. The second connecting rod 7462 drives the second push plate 7463 to slide upward inside the suction cylinder 7461. During the upward movement of the push plate 7463, the telescopic rod 7464 drives the circular plate 7466 to move upward synchronously until the circular plate 7466 precisely abuts against the material drop hole 7469 at the bottom of the guide plate 7468, blocking the impurity backflow channel. As the push plate 7463 continues to move upward, the telescopic rod 7464 is compressed and contracts, and the connecting spring 7465 sleeved on the outside of the telescopic rod 7464 is compressed synchronously. During the upward movement of push plate 7463, the gas and some impurities stored in suction cylinder 7461 are simultaneously pushed out through one-way discharge valve 7467.
