Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1 to 9 , in the embodiment of the present invention, a simple manual chip mounting device includes a base 1.

A suction pen 4 is slidably connected to the outer wall of the mounting seat 3. The bottom end of the suction pen 4 is rotatably connected to a suction head 5. The top end of the suction pen 4 is rotatably connected to a rotating block 6. A suction pipe 7 is connected to the outer wall of the suction pen 4.

[0031] A fixing mechanism 8 is provided between the base 1, the adjusting frame 2 and the mounting seat 3. The fixing mechanism 8 includes a fixing screw rod 801 and a rotating disk 802. The fixing screw rod 801 is fixedly connected to the inner wall of the base 1 and penetrates through the adjusting frame 2. The rotating disk 802 is rotatably connected to the inside of the adjusting frame 2 and is located on the outer wall of the fixing screw rod 801. A clamping block 803 located above the rotating disk 802 is slidably connected to the inside of the adjusting frame 2. A sliding block 804 extending into the inside of the adjusting frame 2 is slidably connected to the outer wall of the adjusting frame 2. A fixing groove 805 is provided on the inner wall of the mounting seat 3. A fixing block 806 is fixedly connected to one end of the outer wall of the sliding block 804 facing the fixing groove 805. A connecting frame 807 extending into the inside of the mounting seat 3 is fixedly connected to the outer wall of the suction pen 4;

[0032] The shielding mechanism 9 is arranged inside the suction pen 4. The shielding mechanism 9 includes an air inlet groove 901 and a rotating ring 902. The air inlet groove 901 is arranged between the inner wall of the suction pipe 7 and the inner wall of the suction pen 4. The rotating ring 902 is rotatably connected inside the suction pen 4 and penetrates through the air inlet groove 901. An active frame 903 extending to the outer wall of the connecting frame 807 is slidably connected inside the suction pen 4. A pushing block 905 in contact with the rotating ring 902 is slidably connected inside the suction pen 4.

[0033] In this embodiment: The adjusting frame 2 slides on the inner wall of the base 1, and the mounting seat 3 slides on the outer wall of the adjusting frame 2. The position of the suction pen 4 is adjusted through the displacement of the mounting seat 3. When the suction pen 4 is displaced downward, the suction pen 4 is fixed by the fixing mechanism 8 when it is displaced downward to prevent the suction pen 4 from shifting in position. Through the shielding mechanism 9, when the suction pen 4 is displaced downward to suck the component, after the suction pen 4 is reset, its position is adjusted to a proper position. When the suction pen 4 is displaced downward, the component is moved to a proper position, and at the same time, the sucking of the component is stopped.

[0034] Please refer with emphasis to Figures 1 - 6 A connecting spring 808 is connected between the connecting frame 807 and the mounting seat 3. A reset plate 809 is fixedly connected to the outer wall of the clamping block 803, and a reset spring 810 is connected between the bottom end of the reset plate 809 and the adjusting frame 2.

[0035] In this embodiment: The adjusting frame 2 slides on the inner wall of the base 1. The displacement of the adjusting frame 2 drives the rotating disk 802 to displace on the outer wall of the fixed lead screw 801, thereby driving the rotating disk 802 to rotate. When the suction pen 4 is displaced downward, it drives the connecting frame 807 to displace. The displacement of the connecting frame 807 contacts the inclined surface of the slider 804 to drive the slider 804 to displace. The displacement of the slider 804 drives the fixed block 806 to displace. The fixed block 806 displaces out of the adjusting frame 2 and enters the fixing groove 805 to fix the adjusting frame 2 and the mounting seat 3. At the same time, the displacement of the slider 804 drives the clamping block 803 to displace downward. The displacement of the clamping block 803 contacts the groove of the rotating disk 802 to fix the rotating disk 802, thereby fixing the mounting seat 3, which is convenient for fixing the mounting seat 3 when the suction pen 4 is displaced downward to prevent the suction pen 4 from shifting in position due to force.

[0036] Please refer with emphasis to Figures 7 - 9 An active spring 904 is connected between the active frame 903 and the connecting frame 807.

A helical tooth 908 is arranged at the top end of the outer wall of the rotating ring 902. A ventilation hole 909 penetrating through the rotating ring 902 is arranged between the displacement block 907 and the helical tooth 908 on the outer wall of the rotating ring 902.

[0037] In this embodiment: The suction pen 4 moves downward to drive the connecting frame 807 to move downward. When the connecting frame 807 moves to the bottom end, the movable frame 903 moves. A slope is provided at the bottom end of the displacement block 907. When the movable frame 903 moves and contacts the slope at the bottom end of the displacement block 907, it drives the displacement block 907 to perform a circular displacement. The circular displacement of the displacement block 907 drives the rotating ring 902 to rotate. The helical tooth 908 contacts the hemispherical surface of the pushing block 905 to drive the pushing block 905 to move. The pushing block 905 moves and contacts the slope of the next helical tooth 908. After the suction pen 4 resets upward, the movable frame 903 is reset under the elastic force of the movable spring 904, and the pushing block 905 moves under the elastic force of the pushing spring 906 to contact the slope of the helical tooth 908. The movement of the pushing block 905 drives the rotating ring 902 to rotate. When the pushing block 905 reaches the connection position of the two helical teeth 908, and at the same time the movable frame 903 is below the slope at the bottom end of the next displacement block 907. When the suction pen 4 moves downward once, it drives the rotating ring 902 to rotate. The rotating ring 902 blocks the air intake groove 901, thereby stopping the suction at the suction head 5. After the suction pen 4 moves again, it drives the rotating ring 902 to rotate, and the ventilation hole 909 contacts the air intake groove 901, so that the suction head 5 sucks air, which is convenient to drive the suction pen 4 to automatically suck air and stop when the suction pen 4 moves downward.

The outer wall of the slider 804 contacts the slope of the clamping block 803. The inner wall of the fixed slot 805 fits with the outer wall of the fixed block 806.

[0041] In this embodiment: When the suction pen 4 moves downward, it drives the connecting frame 807 to move. The movement of the connecting frame 807 contacts the slope of the slider 804 to drive the slider 804 to move. The movement of the slider 804 drives the fixed block 806 to move. The fixed block 806 moves out of the adjusting frame 2 and into the fixed slot 805 to fix the adjusting frame 2 and the mounting seat 3.

[0042] Please refer specifically to Figures 1 - 6, a connecting groove matching the outer wall of the connecting frame 807 is arranged inside the mounting seat 3. One end of the slider 804 away from the fixed block 806 is provided with an inclined surface, and the connecting frame 807 is located above the inclined surface of the slider 804.

[0043] In this embodiment: the displacement of the slider 804 drives the clamping block 803 to move downward. The displacement of the clamping block 803 contacts the groove of the rotating disk 802 to fix the rotating disk 802, thereby fixing the mounting seat 3.

[0044] Please refer to Figures 7 - 9 , a rotating groove matching the outer wall of the rotating ring 902 is arranged inside the suction pen 4, and the air inlet groove 901 runs through the rotating groove and is connected to the inner wall of the suction pen 4.

[0045] In this embodiment: after the suction pen 4 is reset upward, the movable frame 903 is reset under the elastic force of the movable spring 904. The pushing block 905 is displaced under the elastic force of the pushing spring 906 and contacts the inclined surface of the helical tooth 908. The displacement of the pushing block 905 drives the rotating ring 902 to rotate until the pushing block 905 reaches the connection position of the two helical teeth 908.

[0046] Please refer to Figures 7 - 9 , the suction head 5 and the rotating block 6 are fixedly connected by a fixing frame. One end of the pushing block 905 contacts the helical tooth 908, and the end of the pushing block 905 in contact with the helical tooth 908 is a hemispherical surface.

[0047] In this embodiment: the downward displacement of the suction pen 4 drives the connecting frame 807 to move downward. When the connecting frame 807 moves to the bottom end, the movable frame 903 moves. The bottom end of the displacement block 907 is provided with an inclined surface. The displacement of the movable frame 903 contacts the inclined surface at the bottom end of the displacement block 907 and drives the displacement block 907 to perform a circular displacement.
