One end of the installation component slides through the second support plate and extends to the outside of the second support plate to be rotatably installed with a clamping mechanism. One side of the clamping mechanism is slidably clamped with one side of the wire spool; by setting the installation component and the clamping mechanism, while not interfering with the rotation of the wire spool, the wire spool is supported and fixed.

[0025] As a further implementation of the above technical solution: an activity hole is opened inside the other fixed seat 2, the inside of the activity hole is attached to the side of the limiting rod 8, and the fixed seat 2 is convenient for limiting the rotating rod 3 and the rotating shaft 7.

[0026] As a further implementation of the above technical solution: A first limiting hole is formed on the other side of the spool body 5, and the inside of the first limiting hole is in contact with the side surface of the first limiting shaft 4. A second limiting hole is formed on one side of the spool body 5, and the inside of the second limiting hole is in contact with the side surface of the second limiting shaft 6. The first limiting shaft 4 facilitates the limitation of the spool body 5.

[0027] As a further implementation of the above technical solution: A moving groove is formed on one side of the fixed box 9, and the inside of the moving groove is in contact with the side surface of the push plate 12. The fixed box 9 facilitates the limitation of the limiting block 10.

[0028] During specific implementation: The bonding wire is wound by the spool body 5. The spool body 5 is limited by the first limiting shaft 4 and the second limiting shaft 6. The spool body 5 is driven to rotate by the rotating rod 3 and the rotating shaft 7. When disassembling the spool body 5, the limiting block 10 is lifted by the push plate 12, so that the limiting rod 8 loses its limitation. The limiting rod 8 is moved to the right, so that the second limiting shaft 6 is separated from the spool body 5, so that the spool body 5 loses its limitation. The spool body 5 is moved to the right, so that the first limiting shaft 4 is separated from the spool body 5, so that the spool body 5 can be removed. The spool body 5 is moved to the left, so that the first limiting shaft 4 enters the inside of the spool body 5. The limiting rod 8 is moved to the left, so that the second limiting shaft 6 enters the spool body 5. The push plate 12 is released, and the limiting block 10 is squeezed by the return spring 11, so that the limiting block 10 enters the limiting rod 8, so that the limiting rod 8 and the second limiting shaft 6 are limited and cannot move, so that the spool body 5 is limited by the first limiting shaft 4 and the second limiting shaft 6 and cannot move, so as to complete the disassembly and assembly of the spool body 5. The whole process only needs to move the push plate 12 and the limiting rod 8 to disassemble and assemble the spool body 5, so that the spool body 5 is easy to disassemble and assemble. When replacing the spool body 5 with a smaller width, the limiting rod 8 is moved to the left, so that the distance between the first limiting shaft 4 and the second limiting shaft 6 is reduced, so that the first limiting shaft 4 and the second limiting shaft 6 can limit the spool body 5 with a smaller width. The limiting rod 8 is moved to the right, so that the distance between the first limiting shaft 4 and the second limiting shaft 6 is increased, so that the first limiting shaft 4 and the second limiting shaft 6 can limit the spool body 5 with a larger width. After the position of the second limiting shaft 6 is adjusted, the push plate 12 is released, and the limiting block 10 is squeezed by the return spring 11, so that the limiting block 10 enters the corresponding limiting groove, so that the limiting rod 8 and the second limiting shaft 6 are stably limited, so that the limiting rod 8 can still be stably limited after changing its position, so that the device can stably limit the spool body 5 with different widths on the premise of high disassembly and assembly efficiency of the spool body 5, thus improving the application range of the device.

[0029] As a further implementation of the above technical solution: Two spring rods 13 are fixedly arranged at the top end of the base 1. The top ends of the telescopic ends of the two spring rods 13 are provided with a fixing plate 14. The bottom end of the fixing plate 14 is fixedly connected to the top ends of the telescopic ends of the two spring rods 13 respectively. The fixing plate 14 is convenient for limiting the positioning block 15.

[0030] As a further implementation of the above technical solution: Two positioning grooves are opened at the top end of the fixing plate 14. Two positioning blocks 15 are arranged inside the two positioning grooves respectively. A pressing plate 16 is arranged at the top ends of the two positioning blocks 15. The bottom end of the pressing plate 16 is fixedly connected to the top ends of the two positioning blocks 15 respectively. The positioning block 15 is convenient for limiting the pressing plate 16.

[0031] As a further implementation of the above technical solution: A limiting box 17 is fixedly arranged at the bottom end of the fixing plate 14. An installation block 18 is arranged inside the limiting box 17. A number of installation grooves are opened at the bottom end of the pressing plate 16. The side surface of the installation block 18 is fitted with the inside of one of the installation grooves. The limiting box 17 is convenient for limiting the installation block 18.

[0032] As a further implementation of the above technical solution: A positioning spring 19 is fixedly arranged at the bottom end of the installation block 18. The bottom end of the positioning spring 19 is fixedly connected to the bottom end inside the limiting box 17. A pressing plate 20 is fixedly arranged on one side of the installation block 18. The pressing plate 20 is convenient for driving the installation block 18 to move.

[0033] During specific implementation: During the process of winding the bonding wire on the spool body 5, the pressing plate 16 ensures that the gold wire maintains an appropriate tension during the winding process, while keeping the gold wire layer neat and tight. The internal spring of the spring rod 13 applies a force to the telescopic end of the spring rod 13, thereby applying a force to the pressing plate 16, so that the pressing plate 16 does not affect the winding of the gold wire when pressing the gold wire. When replacing the spool body 5 with different widths, the pressing plate 16 needs to be replaced according to the width of the spool body 5, so that the width of the pressing plate 16 is consistent with the width of the spool body 5. Move the fixed plate 14 downward, thereby driving the pressing plate 16 downward. Move the pressing plate 20 downward, so that the mounting block 18 disengages from the pressing plate 16. Replace the pressing plate 16 corresponding to the size of the spool body 5. Move the pressing plate 16 so that the positioning block 15 at the bottom of the pressing plate 16 enters the positioning groove, so that the pressing plate 16 is limited and cannot move up and down. Move the pressing plate 16 left and right so that the pressing plate 16 is directly below the spool body 5. Loosen the pressing plate 20, and squeeze the mounting block 18 through the positioning spring 19, so that the mounting block 18 moves upward into the corresponding mounting groove, so that the pressing plate 16 is limited and cannot move, completing the disassembly and assembly of the pressing plate 16. The pressing plate 16 can be disassembled and assembled by moving the pressing plate 20 and the pressing plate 16, so that the device can easily replace the pressing plate 16 with the corresponding width according to the width of the spool body 5, thereby further improving the application range of the device and facilitating the improvement of the pressing efficiency of the pressing plate 16.
