Technical Field

[0001] This utility model relates to the field of PIN pin correction technology, and in particular to a chip PIN pin correction device. Background Technology

[0002] Chip pin alignment technology is a crucial technique in electronic packaging used to ensure accurate mating of chip pins. During chip manufacturing and packaging, chip pins need to connect to external circuits, and any pin misalignment can lead to poor circuit connections or signal transmission problems. Pin alignment technology uses high-precision equipment and methods to correct pin offsets or bends, ensuring that the chip precisely aligns with pads on the PCB (Printed Circuit Board) during installation. Common alignment methods include mechanical bending and laser alignment. This technology is significant for improving chip reliability, reducing product failure rates, and ensuring stable operation of electronic devices. With the continuous development of chip packaging technology, pin alignment technology is also constantly being optimized to adapt to the smaller size and higher precision requirements of modern chips.

[0003] Existing PIN correction devices mainly use external heating for correction. However, in actual use, they cannot accurately position and fix the chip PINs, which makes the PINs prone to errors. This leads to deformation during correction and reduces the accuracy and stability of chip PIN correction.

[0004] Therefore, a chip PIN correction device is proposed to address the above problems. Utility Model Content

The high-temperature heating mechanism includes a fixing block fixedly connected to the top of the base. A cover plate is rotatably connected to the outer surface of the fixing block. Three thermal contact rods are fixedly installed at the bottom of the cover plate. Four circular holes I are opened at the top of the base. Electromagnets I are fixedly connected to the inner surfaces of the four circular holes I. Four circular holes II are opened at the bottom of the cover plate. Electromagnets II are fixedly installed on the inner surfaces of the four circular holes II.

[0007] Preferably, three positioning rods are fixedly installed at the bottom end of the cover plate, and the three positioning rods are made of flexible material.

[0008] Preferably, the top of the base is provided with a positioning groove, and a positioning block is fixedly connected to the bottom of the inner surface of the positioning groove.

[0014] 1. This utility model provides a chip PIN needle straightening device. Through a high-temperature heating mechanism, electromagnets one and two are heated. Heat is transferred through a thermal contact rod, which then heats and softens the PIN needle. Through precise positioning and limiting operations, the accurate position of the PIN needle body on the base is ensured.

[0021] 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.

[0022] Specific implementation examples are given below.

[0023] Please see Figure 1 - Figure 4A chip PIN needle straightening device includes a base 1 and a PIN needle body 4. A high-temperature heating mechanism 2 and a straightening mechanism 3 are provided at the top of the base 1. The high-temperature heating mechanism 2 includes a fixing block 21 fixedly connected to the top of the base 1. A cover plate 22 is rotatably connected to the outer surface of the fixing block 21. Three thermal contact rods 27 are fixedly installed at the bottom of the cover plate 22. Four circular holes 23 are formed at the top of the base 1, and electromagnets 24 are fixedly connected to the inner surfaces of each of the four circular holes 23. Four circular holes 25 are formed at the bottom of the cover plate 22, and electromagnets 26 are fixedly installed to the inner surfaces of the four circular holes 25. A positioning groove 211 is formed at the top of the base 1, and a positioning block 212 is fixedly connected to the bottom of the inner surface of the positioning groove 211. Three positioning rods 28 are fixedly installed at the bottom of the cover plate 22. These three positioning rods 28 are made of flexible material. During use, the PIN needle body 4 is placed on the inner surface of the positioning groove 211 on the base 1, and the round hole on the PIN needle body 4 is inserted into the positioning block 212, initially limiting the position of the PIN needle body 4. Then, the cover plate 22 is rotated, causing it to move downwards and fix the PIN needle body 4. Simultaneously, the three thermal contact rods 27 can contact the PIN needle on the PIN needle body 4, and the positioning rods 28 further limit the position of the PIN needle body 4. It connects to an external power source and performs heating operations through electromagnets 24 and 26. Heat is transferred through the thermal contact rod 27, which then heats and softens the PIN pin. Through precise positioning and limiting operations, the accurate position of the PIN pin body 4 on the base 1 is ensured. After rotating the cover plate 22, the thermal contact rod 27 contacts the PIN pin body 4, and the PIN pin is softened by heating through the electromagnet, thereby achieving precise correction. This process can effectively control the shape and position of the PIN pin, avoid positional errors or deformation, and improve the accuracy and stability of chip PIN pin correction.

[0024] The electromagnets 24 and 26 mentioned above are mature heating technologies and equipment in the prior art. This solution utilizes their electromagnetism for heating. Furthermore, the distribution of the S and N poles of electromagnets 24 and 26 in this solution can be changed according to actual usage requirements. The internal structure, principle, and connection method of these electromagnets will not be described in this solution.

[0025] The thermal contact rod 27 mentioned above is a mature heat transfer technology and equipment in the prior art, and its internal structure, principle and connection method will not be described further.

[0026] like Figure 2 , Figure 3 and Figure 4As shown, the top of the base 1 has four threaded holes 29, and the inner surfaces of the four threaded holes 29 are threaded with bolts 210. By setting the threaded holes 29 and bolts 210, the base 1 can be installed and fixed with external equipment during use, which is convenient for use.

[0027] like Figure 3 and Figure 4 As shown, the correction mechanism 3 includes two sliding grooves 31 at the top of the base 1. The inner surfaces of the two sliding grooves 31 are slidably connected to correction claws 32. Three correction holes 33 are provided on one side of the correction claws 32. The three correction holes 33 are linearly and equidistantly distributed. When the PIN pin is heated, the correction claws 32 are held in hand, so that the correction claws 32 can slide back and forth on the inner surface of the sliding grooves 31, and the correction holes 33 can reciprocate to contact the PIN pin. This allows the softened PIN pin to be limited by the inner wall of the correction holes 33, thereby realizing the correction of the PIN pin. This ensures the accurate correction of the PIN pin, avoids positional deviation or deformation, and improves the accuracy and efficiency of chip PIN pin correction.

[0028] like Figure 4 As shown, the corrective claw 32 has two limiting holes 34 on one side, and two limiting rods 35 are fixedly connected to one side of the base 1. The size and shape of the inner surface of the limiting hole 34 are adapted to the size and shape of the outer surface of the limiting rod 35. The movement position of the corrective claw 32 can be precisely limited by the limiting hole 34 and the limiting rod 35, thereby improving the accuracy of the movement of the corrective claw 32.

[0029] The working principle of this utility model is as follows: During use, the PIN needle body 4 is placed on the inner surface of the positioning groove 211 on the base 1, and the round hole on the PIN needle body 4 is inserted into the positioning block 212 to initially limit the position of the PIN needle body 4. Then, the cover plate 22 is rotated, causing it to move downwards and fix the PIN needle body 4. Simultaneously, the three thermal contact rods 27 can contact the PIN needle on the PIN needle body 4, and the positioning rod 28 further limits the position of the PIN needle body 4. At this time, it is connected to an external power source, and heating is performed by electromagnets 24 and 26. Heat is transferred through the thermal contact rods 27, subsequently heating and softening the PIN needle. Through precise positioning and limiting operations, the PIN needle body 4 is ensured to remain in its correct position. The pin is accurately positioned on the base 1. After rotating the cover plate 22, the thermal contact rod 27 contacts the PIN body 4. Heating by an electromagnet softens the PIN, thus achieving precise correction. This process effectively controls the shape and position of the PIN, avoiding positional errors or deformation, and improving the accuracy and stability of chip PIN correction. While heating the PIN, the correction claw 32 is held so that it can slide back and forth on the inner surface of the slide groove 31, allowing the correction hole 33 to reciprocate to contact the PIN. The softened PIN can be limited by the inner wall of the correction hole 33, achieving the correction operation of the PIN. This ensures precise correction of the PIN, avoids positional deviations or deformation, and improves the accuracy and efficiency of chip PIN correction.
