By arranging the light shield 320 at the end of the light source 310 away from the lens 120 along the preset direction, the influence of external stray light on the glue drop can be avoided.

[0063] In addition, the distance between the light source 310 and the light shield 320 along the preset direction is adjustable. By adjusting the relative distance between the light source 310 and the light shield 320 along the preset direction, the shielding effect of the light shield 320 on external stray light can be further improved.

The driving member 210 is used to drive the lead screw to rotate around the preset direction. When it is necessary to drive the industrial camera 110 and the lens 120 to move along the preset direction, the driving member 210 drives the lead screw to rotate around the axis of itself, which can drive the nut sleeved on the outer periphery of the lead screw to rotate around the preset axis and move along the preset axis, thereby driving the mounting seat 130 rotationally connected to the nut to move along the preset axis. The effect of driving the industrial camera 110 and the lens 120 to move along the preset direction is achieved. It should be noted that in the embodiment, the driving member 210 is a rotary motor. The rotary motor has simple structure, easy disassembly and assembly, and stable output power. In other embodiments, the driving member 210 can also be a rotary air cylinder or other rotary driving structure, which is not limited in the embodiment. It can be understood that the rotation direction of the driving member 210 to the lead screw can be adjusted to drive the industrial camera 110 and the lens 120 to move forward or backward along the preset direction. In addition, as shown in FIG. 2, the driving assembly 200 is arranged on the base 600. The driving assembly 200 can be arranged on the mounting seat 130.

[0068] In an optional solution, as shown in Figure 5 The glue drop observation device further comprises a detection assembly 900 and a control assembly, wherein the detection assembly 900 is used to detect whether the mounting seat 130 moves to the preset position along the preset direction, the control assembly is in communication connection with the driving member 210 and the detection assembly 900 respectively, and the control assembly is used to control the start and stop of the driving assembly 200. By arranging the control assembly in communication connection with the detection assembly 900 and the driving member 210 respectively, when the detection assembly 900 detects that the mounting seat 130 moves to the preset position along the preset direction, the detection assembly 900 transmits the detection information to the control assembly, and the control assembly controls the driving member 210 to be closed according to the detection information of the detection assembly 900, so as to avoid the driving member 210 driving the mounting seat 130 to pass the preset position.

By arranging the first preset position and the second preset position at intervals along the preset direction, the mounting seat 130 moves between the first preset position and the second preset position, the light blocking piece 920 is arranged on the mounting seat 130, when the light blocking piece 920 moves to the first preset position or the second preset position, the light blocking piece 920 triggers the photoelectric detection piece 910 at the corresponding position, the photoelectric detection piece 910 transmits detection information to the control assembly, and the control assembly closes the driving piece 210 according to the detection information, so as to prevent the mounting seat 130 from crossing the first preset position or the second preset position along the preset direction.

[0070] Specifically, as shown in Figure 5 The photoelectric detection piece 910 is provided with a light transmission groove 911, the two side walls of the light transmission groove 911 are respectively provided with a light emitting piece and a butt joint piece, the light emitting piece sends butt joint light to the butt joint piece, when the light blocking piece 920 moves to the first preset position or the second preset position along with the mounting seat 130, the light blocking piece 920 extends into the light transmission groove 911 and prevents the butt joint light emitted by the light emitting piece from being transmitted to the butt joint piece, after the butt joint piece fails to receive the butt joint light, the butt joint piece transmits detection information to the control assembly, and the control assembly closes the driving piece 210 according to the detection information.

[0071] It should be noted that in the embodiment, the first preset position and the second preset position are both located in the extension range of the guide sliding rail 510 in the guide assembly 500. When the mounting seat 130 moves to the first preset position and the second preset position along the preset direction, the mounting seat 130 stops moving, at this time, the guide sliding block 520 in the guide assembly 500 has not abutted against the stop piece 530, so as to further improve the protection of the guide sliding block 520 and the stop piece 530.

[0072] In some alternative solutions, the droplet observation device further includes a first protective cover 700 and a second protective cover 800. The first protective cover 700 covers the outer periphery of the imaging component 100 and has first openings at both ends along a preset direction. The second protective cover 800 covers the outer periphery of the lighting component 300 and has second openings at both ends along a preset direction. By using the first protective cover 700 to cover the outer periphery of the imaging component 100 and the second protective cover 800 to cover the outer periphery of the lighting component 300, and by providing first openings at both ends of the first protective cover 700 and second openings at both ends of the second protective cover 800 along the preset direction, the protection of the imaging component 100 and the lighting component 300 can be further improved while ensuring their normal operation.

[0073] In addition, in this embodiment, in order to further improve the shooting effect of the shooting component 100, both the first protective cover 700 and the second protective cover 800 are made of black material, and neither the first protective cover 700 nor the second protective cover 800 guides light, so as to further eliminate the influence of external stray light on the shooting component 100 and the lighting component 300.
