[0029] Please see Figures 1 to 5This utility model provides an anti-interference adjustable multi-laser pin detection light source device, which includes a housing 100 and a detection light source assembly 200. The housing 100 includes a base plate 110 and an outer cover 120. A first opening 111 is provided in the middle of the base plate 110, and the first opening 111 is arranged vertically. Two outer covers 120 are provided, and are respectively arranged at both ends of the base plate 110 along a first horizontal direction. The top of the outer cover 120 and the top of the base plate 110 are defined. The base plate 110 has a side opening 121 and a receiving space 122. The side opening 121 and the receiving space 122 are connected. Two outer covers 120 are spaced apart and symmetrically arranged with respect to the second horizontal direction. The two side openings 121 are arranged opposite each other along the first horizontal direction. The first horizontal direction and the second horizontal direction are perpendicular to each other. Multiple detection light source assemblies 200 are provided. The multiple detection light source assemblies 200 are all located at the top of the base plate 110 and are respectively located in the two receiving spaces 122. The detection light source assembly 200 includes a linear laser beam. The laser component 210, sleeve structure 220, first connector, and grommets are included. The laser component 210 is rotatably mounted within the sleeve structure 220. The first connector detachably connects the sleeve structure 220 and the base plate 110. The sleeve structure 220 is provided with adjustment holes 221, which are vertically continuous.

[0030] 1. In this embodiment of the utility model, the pin can be placed above the first opening 111 and between the two side openings 121, so that the linear laser element 210 can illuminate the pin. By setting the first opening 111, the reflected light received by the pin can be reduced, and the CCD camera module can easily detect the pin. The linear laser element 210 has a better detection effect on pins with fine structures. Furthermore, the linear laser element 210 is rotatably connected to the sleeve structure 220, so that the linear laser element 210 can rotate relative to the sleeve structure 220 to adjust the flatness of the light emitted by the linear laser element 210, which has a better adaptability to pins with fine structures and ensures the detection accuracy of the CCD camera module. The sleeve structure 220 is provided with... The adjustment hole 221 allows the grommets inside to extend from the bottom of the adjustment hole 221 and abut against the base plate 110. By setting four adjustment holes 221 on both sides of the sleeve structure 220 and rotating the four grommets, the position between the sleeve structure 220 and the base plate 110 can be controlled to adjust the tilt of the sleeve structure 220 relative to the base plate 110. This adjusts the flatness of the light emitted by the laser component 210, further improving the adaptability to pins with fine structures and thus improving the detection accuracy of the CCD camera module pins. After adjustment, the sleeve structure 220 is fixedly installed on the base plate 110 by the first connector to limit the position of the detection light source assembly 200 and improve the stability of the detection.

[0031] 2. The outer cover 120 is installed at opposite ends of the base plate 110. The detection light source assembly 200 is set in the accommodating space 122 to protect the detection light source assembly 200 and block ambient light, thereby reducing the influence of ambient light on the linear laser component 210 of the detection light source assembly 200 and ensuring detection accuracy.

[0032] Reference Figures 2 to 4 In some embodiments of this utility model, the sleeve structure 220 includes a first sleeve 230, a second sleeve 240, and a second connecting member; the first sleeve 230 is rotatably sleeved on the outside of the one-line laser component 210, and the second sleeve 240 is rotatably sleeved on the outside of the first sleeve 230; an adjustment hole 221 is provided on the second sleeve 240; the first connecting member is detachably connected to the second sleeve 240 and the base plate 110; a second through-hole 231 is provided on the first sleeve 230, and an arc-shaped through-groove 241 is provided on the second sleeve 240, the arc-shaped through-groove 241 extends along a second horizontal direction, and the second through-hole 231 and the arc-shaped through-groove 241 are arranged opposite to each other; the second connecting member passes through the arc-shaped through-groove 241 and the second through-hole 231, and is detachably connected to the first sleeve 230 and the one-line laser component 210; the second connecting member is movably disposed within the arc-shaped through-groove 241.

[0033] The first sleeve 230 and the second sleeve 240 are both disposed through the first horizontal direction. The first sleeve 230 is fitted over the linear laser component 210, allowing the linear laser component 210 to rotate within the first sleeve 230 to adjust its position. The second sleeve 240 is fitted over the first sleeve 230, allowing the first sleeve 230 to rotate within the second sleeve 240 to adjust its position. By rotating the first sleeve 230 to adjust the position of the linear laser component 210, the degree of wear between the linear laser component 210 and the first sleeve 230 can be reduced, ensuring that the linear laser component 210 can work normally.

[0034] The second sleeve 240 is fitted over the first sleeve 230. The first connector detachably connects the second sleeve 240 and the base plate 110 to limit the position of the linear laser component 210, making it impossible to continue adjusting the position of the linear laser component 210 by means of the caliper screw.

[0035] The second connector passes through the arc-shaped groove 241 and the second opening 231 and abuts against the line laser component 210. The friction between the end of the second connector and the line laser component 210 connects the first sleeve 230 and the line laser component 210. The arc-shaped groove 241 on the second sleeve 240 surrounds the periphery of the second cylinder 243 and extends along the second horizontal direction. By driving the second connector to move within the arc-shaped groove 241, the first sleeve 230 can rotate relative to the second sleeve 240, which facilitates the adjustment of the flatness of the light emitted by the line laser component 210.

[0036] Specifically, the second connector is a nut screw structure.

[0037] In some embodiments of this utility model, the sleeve structure 220 further includes a third connector, which is detachably connected to the first sleeve 230 and the second sleeve 240.

[0038] After adjusting the relative positions of the first cylinder 243 and the second cylinder 243 through the second connector, the first sleeve 230 and the second sleeve 240 can be fixedly connected through the third connector to limit the position between the first sleeve 230 and the second sleeve 240 and reduce the possibility of the first sleeve 230 being accidentally rotated by external factors; specifically, the third connector is a nut screw structure.

[0039] Reference Figures 2 to 4 In some embodiments of this utility model, the second sleeve 240 is provided with a third through-hole 242, which is provided through in the vertical direction; the third connector is detachably provided in the third through-hole 242 and abuts against the first sleeve 230.

[0040] The friction between the third connector and the first sleeve 230 is used to connect and fix the first sleeve 230 and the second sleeve 240, thereby defining the position between the first sleeve 230 and the second sleeve 240.

[0041] Reference Figures 3 to 5 In some embodiments of this utility model, the base plate 110 is provided with a plurality of first connecting holes 112, and the second sleeve 240 is provided with a second connecting hole 245. The first connecting holes 112 and the second connecting holes 245 are arranged opposite to each other. The first connector is detachably inserted through the first connecting holes 112 and the second connecting holes 245 so as to fix the second sleeve 240 on the base plate 110.

[0042] Specifically, both the first connecting hole 112 and the second connecting hole 245 are threaded holes, and the first connector is a screw structure.

[0043] Reference Figure 3 and Figure 4 In some embodiments of this utility model, the second sleeve 240 includes a cylinder 243 and a placement plate 244; the cylinder 243 is rotatably sleeved outside the first sleeve 230; the cylinder 243 is disposed at the top center of the placement plate 244; the adjustment hole 221 and the second connecting hole 245 are both disposed on the placement plate 244.

[0044] The bottom end of the placement plate 244 is used to abut against the top end of the base plate 110. Two of the four adjustment holes 221 are located at one end of the placement plate 244 in the second horizontal direction, and the other two are located at the other end of the placement plate 244 in the second horizontal direction. There are two second connection holes 245, which are respectively located at both ends of the placement plate 244 along the second horizontal direction.

[0045] Specifically, the cylinder 243 and the placement plate 244 are integrally formed.

[0046] Reference Figure 3 and Figure 4 In some embodiments of this utility model, a limiting boss 232 is provided at one end of the first sleeve 230 along the first horizontal direction, and the limiting boss 232 abuts against the end of the second sleeve 240.

[0047] By setting the limiting boss 232, the position between the first sleeve 230 and the second sleeve 240 can be limited, reducing the difficulty of installation.

[0048] In some embodiments of this utility model, a control component is also included. The control component is connected to a plurality of linear laser elements 210 and is capable of driving the linear laser elements 210 to start and stop.

[0049] Specifically, the control component can control the individual start-up and shutdown of the single-line laser element 210 of multiple detection light source components 200, and can individually control the brightness of the light emitted by the single-line laser element 210, thereby improving the adaptability of the detection.

[0050] In some embodiments of this utility model, adjacent detection light source components 200 are spaced apart to avoid damage caused by mutual squeezing between adjacent detection light source components 200.

[0051] Reference Figure 1 and Figure 2 In some embodiments of this utility model, in the vertical direction, the outer cover 120 is at least partially offset from the first opening 111 so as to avoid the outer cover 120 blocking the first opening 111.

[0052] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
