[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0029] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0030] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a circuit board Mark point auxiliary positioning device.

[0031] Example 1:

[0032] Combination Figure 1-5 As shown, the present invention provides a circuit board Mark point auxiliary positioning device, including a positioning mechanism 100. The positioning mechanism 100 includes a right-angle plate 110, a turntable 120 rotatably connected to the top of the right-angle plate 110, a guide rail 130 movably connected to the turntable 120, two sliders 140 slidably mounted on the guide rail 130, a pad 150 connected to the top of the sliders 140, and a cross laser 160 connected to the top of the pad 150. The sliders 140 have a circular opening.

[0033] Furthermore, the turntable 120 is composed of a protruding rod 121 and a base plate 122. The base plate 122 is fixed to the top of the protruding rod 121. The protruding rod 121 is rotatably embedded in the top of the right angle plate 110. The bottom of the base plate 122 is in contact with the top of the right angle plate 110.

[0034] Furthermore, the thickness of the guide rail 130 is less than the thickness of the base plate 122, and the top of the guide rail 130 is on the same horizontal plane as the top of the base plate 122. The size and layout design of the guide rail 130 ensures that it will not come into contact with the top of the right angle plate 110 when it rotates with the turntable 120, thus ensuring that the guide rail 130 can rotate flexibly.

[0035] Furthermore, the top of the pad 150 is set as an inclined surface, and the cross laser 160 is set at an angle. The layout design of the cross laser 160 ensures that the cross beam emitted by it can be in the center of the circular opening, providing conditions for quickly finding the Mark point.

[0036] Furthermore, silicone rods 500 are fixed to both sides of the slider 140. The silicone rods 500 are attached to the outside of the guide rail 130. The silicone rods 500 increase the contact area between the slider 140 and the guide rail 130, making the slider 140 less prone to sliding under the influence of external forces, and ensuring that the circular opening will not deviate after finding the Mark point.

[0037] Example 2:

[0038] Combination Figure 1 and Figure 5 As shown, based on Embodiment 1, a stabilizing component 200 is provided on the outer side of the right-angle plate 110. The stabilizing component 200 includes a plurality of pads 210 fixed to the outer side of the right-angle plate 110 and a damping plate 220 embedded in the bottom of the pads 210. The bottoms of the pads 210 and the damping plate 220 are flush with the bottom of the right-angle plate 110. The pads 210 and the damping plate 220 cooperate to reduce the probability of displacement of the right-angle plate 110 during use.

[0039] Example 3:

[0040] Combination Figure 1 and Figure 5 As shown in the above embodiment, a right-angle groove 300 is provided on the inner side of the right-angle plate 110. A rubber strip 400 is installed on the top of the inner cavity of the right-angle groove 300. After the edge of the circuit board is attached to the inner wall of the right-angle groove 300, the rubber strip 400 will press against the top of the circuit board to ensure that the circuit board will not move during the positioning of the Mark point and to ensure positioning accuracy.

[0041] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the circuit board is attached to the inside of the right-angle plate 110, and then the guide rail 130 is driven to rotate by the turntable 120 so that the guide rail 130 is aligned with the two Mark points on the circuit board. Then, while the cross laser 160 is turned on, the slider 140 is slid so that the center of the cross laser beam in the circular opening of the slider 140 coincides with the Mark point, thereby completing the auxiliary positioning.

[0042] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
