The outer side of the top end of the first rotating head 34 is sleeved on the bottom end of the first fixed seat 33, and the first rotating head 34 is rotatably connected to the first fixed seat 33. The bottom end of the first rotating head 34 is fixedly connected to the top end of the transmission push rod 35, which is a round rod design. The bottom end of the transmission push rod 35 is fixedly connected to the top end of the second rotating head 36. The bottom end of the second rotating head 36 is sleeved on the outer side of the top end of the second fixed seat 37, and the second rotating head 36 is rotatably connected to the second fixed seat 37. The bottom end of the second fixed seat 37 is fixedly connected to the top end of the push plate 38, and the bottom end of the push plate 38 abuts against the top end of the connector 39, which is a square design. The front and rear ends of the top of the 39 are also fixedly connected with the second positioning rod 48. The top of the second positioning rod 48 is inserted into the installation head 10, and the second positioning rod 48 is slidably connected to the installation head 10. The second positioning rod 48 is a round rod design. The outer side of the suction head body 28 is fixedly connected to the inner wall of the threaded ring 40. The top of the threaded ring 40 is fixedly connected to the bottom of the stop block 41. The outer side of the threaded ring 40 is fitted with a fixed base 42, and the threaded ring 40 is threadedly connected to the fixed base 42. The top of the fixed base 42 is fixedly connected to the bottom of the buffer spring 43. The top of the buffer spring 43 is fixedly connected to the bottom of the top plate 44. The top of the top plate 44 abuts against the bottom of the fixed sleeve 26. The top plate 44 is a round design. During operation, press the pressing plates 16 on both sides above the mounting head 10 inwards simultaneously. When the pressing plates 16 are pressed inwards, they will cause the pressing rod 15 to retract and move along the guide groove 13. At the same time, the pressing rod 15 will compress the first return spring 14 inside the guide groove 13 and retract. Simultaneously, as the pressing rod 15 moves, it will cause the first positioning rod 18 to move along the limiting groove 17 and the fixing sleeve 19 until the first positioning rod 18 is completely disengaged from the fixing sleeve 19. The first fixing bracket 12 is used to fix the position of the fixing block 11, and the second fixing bracket 20 is used to fix the fixing sleeve 19 and the connector 39. After the first positioning rod 18 is completely disengaged... After disengaging from the fixed sleeve 19, the second return spring 32 on the outer side of the guide rod 30 inside the fixed box 29 will automatically rebound, pushing the sliding blocks 31 at both ends of the guide rod 30 to move towards the center simultaneously. As the sliding blocks 31 move towards the center, they will simultaneously drive the first fixed seat 33 and the first rotating head 34 to move. The first rotating head 34 will also rotate along the outer side of the bottom end of the first fixed seat 33, simultaneously driving the transmission push rod 35 to rotate. When the transmission push rod 35 rotates, it will drive the second rotating head 36 to rotate along the outer side of the top end of the second fixed seat 37, applying a downward pushing force to the push plate 38. This push plate 38 will then push the connector 39 downwards. As the connector 39 moves downwards, it will cause the fixing sleeve 26 and the suction head body 28 to move downwards until they are completely disengaged. Simultaneously, the connector 39 moves downwards along the outer side of the bottom end of the mounting head 10, and the second positioning rod 48 moves downwards along the inside of the mounting head 10 until it is completely disengaged. When the air pump body 21 is activated, suction will be generated through the cooperation of the connecting pipe 22 and the pipe head 23. Simultaneously, the drive device 24 will be activated to push the connecting platform 25 and the mounting head 10 downwards. As the mounting head 10 moves downwards, it will simultaneously cause the suction head body 28 to move downwards until the bottom end of the suction head body 28 is in contact with the top of the chip. The resulting suction will cause the suction head body 28 to adsorb and grasp the chip. When the head body 28 moves downward and contacts the top of the chip, and the mounting head 10 continues to move downward, the mounting head 10 will push the fixing sleeve 26 to continue moving downward. When the fixing sleeve 26 moves downward, it will compress the buffer spring 43 at the bottom of the top plate 44 to compress and buffer, and at the same time drive the fixing sleeve 26 to move downward along the outside of the sliding head 27 and the suction head body 28. When the buffer spring 43 needs to be adjusted, simply rotate the fixing base 42 along the outside of the threaded ring 40 and move it downward until it is completely disengaged. Then pull the fixing base 42 downward, which will drive the buffer spring 43 and the top plate 44 to move downward simultaneously until they are completely disengaged. The stop block 41 can limit the fixing base 42.

[0021] Example 2 Please see Figure 7 , Figure 11 and Figure 12 As shown, in contrast to embodiment one as another implementation of the present invention, the inner side of the movable slider 27 is fixedly connected to the third sealing ring 47, the outer side of the third sealing ring 47 abuts against the inner wall of the fixed sleeve 26, the inner wall of the top of the connector 39 is fixedly connected to the outer side of the bottom of the first sealing ring 45, the top of the first sealing ring 45 is inserted into the inner side of the bottom of the mounting head 10, and the first sealing ring 45 is slidably connected to the mounting head 10, the inner wall of the connector 39 is fixedly connected to the outer side of the second sealing ring 46 near the upper position, and the inner wall of the second sealing ring 46 abuts against the outer side of the bottom of the mounting head 10; A chip placement method for a chip placement machine includes the following steps: S1: Pressing the pressing plates 16 on both sides inward to drive the pressing rod 15 and the first positioning rod 18 to move. When the first positioning rod 18 moves, the first positioning rod 18 will move along the limiting slide groove 17 and the inside of the fixing sleeve 19 until it is disengaged from the inside of the fixing sleeve 19, thereby canceling the fixing of the fixing sleeve 19 and the second fixing frame 20 at their positions. S2: When the first positioning rod 18 is disengaged from the fixed sleeve 19 and the fixing is removed, the second return spring 32 on the outside of the guide rod 30 will automatically rebound and push the moving slider 31 to move towards the middle along the outside of the guide rod 30, thereby driving the first fixed seat 33 and the first rotating head 34 to move. The first rotating head 34 drives the transmission push rod 35 to move and rotate at the same time. Thus, the transmission push rod 35 drives the second rotating head 36 to rotate along the top of the second fixed seat 37 and applies a downward pushing force to the push plate 38, thereby pushing the connector 39 to move downward. S3: When the connector 39 moves downward, it will move downward along the outer side of the bottom end of the mounting head 10, while simultaneously moving the fixing sleeve 26 and the suction head body 28 until they are completely detached and the suction head body 28 is removed. S4: Rotating the fixed base 42 will move downward along the outer side of the threaded ring 40 until it is completely disengaged. The stop block 41 can limit the fixed base 42 sleeved on the outer side of the threaded ring 40. At the same time, the downward movement of the fixed base 42 will drive the buffer spring 43 and the top plate 44 to move downward simultaneously until they are completely removed. During operation, the movable slider 27 moves along the inside of the fixed sleeve 26, which will simultaneously drive the third sealing ring 47 to move against the inner wall of the fixed sleeve 26 to achieve a sealing effect. At the same time, when the bottom end of the mounting head 10 is inserted into the fixed sleeve 26, the second sealing ring 46 and the first sealing ring 45 will fit tightly against the inner wall of the mounting head 10 to achieve a sealing effect.

10. A chip placement method for a chip placement machine, applied to a chip placement machine according to any one of claims 1-9, characterized in that: The method includes the following steps: S1: Press the pressing plates (16) on both sides inward to drive the pressing rod (15) and the first positioning rod (18) to move. When the first positioning rod (18) moves, the first positioning rod (18) will move along the limit slide groove (17) and the inside of the fixed sleeve (19) until it is disengaged from the inside of the fixed sleeve (19), thereby canceling the fixation of the fixed sleeve (19) and the second fixed frame (20) at their positions. S2: When the first positioning rod (18) is removed from the fixed sleeve (19) and the fixing is cancelled, the second reset spring (32) on the outside of the guide rod (30) will automatically rebound and push the moving slider (31) to move towards the middle along the outside of the guide rod (30), thereby driving the first fixed seat (33) and the first rotating head (34) to move. The first rotating head (34) drives the transmission push rod (35) to move and rotate at the same time, thereby driving the transmission push rod (35) to drive the second rotating head (36) to rotate along the top of the second fixed seat (37) and apply a downward pushing force to the push plate (38), thereby pushing the connector (39) downward. S3: The connector (39) moves downward and will move downward along the outer side of the bottom of the mounting head (10), while driving the fixing sleeve (26) and the suction head body (28) to move until they are completely separated and the suction head body (28) is removed. S4: Rotate the fixed base (42), which will move downward along the outside of the threaded ring (40) until it is completely disengaged. The stop block (41) can limit the fixed base (42) sleeved on the outside of the threaded ring (40). At the same time, the fixed base (42) moves downward, causing the buffer spring (43) and the top plate (44) to move downward simultaneously until they are completely removed.
