Description

Technical Field

[0001] The present application relates to the technical field of searchlight equipment, and in particular to a cross light source and a shadowless searchlight structure. Background Art

[0002] In the process of surface defect detection of precision workpieces, a high-brightness light source is needed to illuminate the workpiece surface so that the surface features of the workpiece can be enhanced. Among them, the shadowless searchlight source can simultaneously search the workpiece from multiple angles. While enhancing the surface features of the workpiece, it can also effectively weaken the problem of ghosting and lamination of multiple features of the workpiece under light.

[0003] Most existing shadowless searchlight sources include a group of main searchlight sources and multiple groups of auxiliary searchlight sources, wherein the main searchlight source generally uses a searchlight with a relatively high power, and the main searchlight source directly illuminates the workpiece from above. Multiple groups of auxiliary searchlight sources surround the periphery of the main searchlight source and illuminate the workpiece at the same time at a position below the main searchlight source. In the process of simultaneously illuminating the workpiece with a group of main searchlight sources and multiple groups of auxiliary searchlight sources, the surface features of the workpiece can be illuminated without shadow and with high brightness, thereby facilitating the optical inspection equipment to detect the surface defects of the workpiece.

[0004] However, using multiple searchlight sources to simultaneously illuminate a group of workpieces results in a large amount of searchlight equipment used and a waste of resources. In addition, when the number of searchlight devices increases, operators need to debug them, which increases the complexity of searching the workpieces and affects the efficiency of searching the workpieces.

[0024] The embodiment of the present application discloses a cross light source.

[0025] The following is combined with Figure 1-4 This application is described in further detail.

[0026] Reference Figure 1 and Figure 2 A cross light source is used to searchlight a workpiece without shadow by releasing cross searchlight. The cross light source includes a searchlight mechanism 1, a maintenance bracket 2 and a focusing mechanism 3. The searchlight mechanism 1 and the focusing mechanism 3 are sequentially installed in the maintenance bracket 2 along the vertical direction. After the searchlight mechanism 1 emits cross searchlight, the focusing mechanism 3 can first focus the searchlight and then evenly spread it on the workpiece.

[0027] Reference Figure 1 and Figure 2 The maintenance bracket 2 can be a rectangular structure formed by four steel plates fixed by bolts, and the inner cavity of the maintenance bracket 2 is hollow for installation of the searchlight mechanism 1 and the focusing mechanism 3. In addition, both ends of the maintenance bracket 2 in the height direction are designed to be open; wherein, the bottom opening of the maintenance bracket 2 is used for the searchlight emitted by the searchlight mechanism 1 to be searched downward, and the top opening of the maintenance bracket 2 is used for the heat generated by the searchlight mechanism 1 when in use to be dissipated outward.

[0028] Reference Figure 3 and Figure 4 The searchlight mechanism 1 includes a top plate 11 and a plurality of searchlight assemblies 12, wherein the top plate 11 can be a horizontal solid steel plate. The top plate 11 is welded in the side wall of the maintenance bracket 2 in the horizontal direction, and the top plate 11 extends along the length direction of the maintenance bracket 2.

[0029] Reference Figure 3 and Figure 4 All searchlight assemblies 12 are evenly installed on the bottom wall of the top plate 11 along the length direction of the top plate 11. Each group of searchlight assemblies 12 can form cross-searchlight searchlights on the workpiece, and adjacent searchlight assemblies 12 can also form cross-searchlight searchlights on the workpiece.

[0030] Reference Figure 3 and Figure 4 In order to facilitate understanding and explanation, one group of searchlight assemblies 12 is taken as an example for specific explanation. The searchlight assembly 12 includes a support plate 121 and a searchlight bead 122, wherein the number of the support plates 121 can be two. Each support plate 121 is welded obliquely to the bottom wall of the top plate 11, and the angle between the support plate 121 and the top plate 11 is 45°. There is a gap between the two support plates 121 under the same group of searchlight assemblies 12, and the two support plates 121 are distributed in an eight-shaped shape on the top plate 11. The searchlight bead 122 is vertically welded to the side walls of the two support plates 121 facing each other, and the searchlight beads 122 on adjacent support plates 121 are aligned with each other.

[0031] Reference Figure 3 and Figure 4 After the searchlight beads 122 emit searchlight, since the support plates 121 are tilted and the adjacent searchlight beads 122 are aligned with each other, the searchlights emitted by the searchlight beads 122 on the two support plates 121 can form cross-irradiation on the workpiece. In this case, the surface features of the workpiece can be enhanced and displayed, and since the searchlight is cross-irradiated, the workpiece can be searched without shadow. In addition, since there are gaps between adjacent support plates 121, the phenomenon of excessive concentration of cross-irradiated searchlight can be reduced, and the phenomenon of light and shadow on the workpiece is reduced.

[0032] Reference Figure 3 and Figure 4 , and in two adjacent groups of searchlight assemblies 12, a support plate 121 in one group of searchlight assemblies 12 abuts against a support plate 121 in the other group of searchlight assemblies 12 and is perpendicular to each other. In this case, all searchlight assemblies 12 can be symmetrical with each other based on the vertical plane position, that is, all searchlight assemblies 12 form an array distribution on the bottom wall of the top plate 11, so that adjacent searchlight assemblies 12 can also form cross-irradiation, effectively ensuring that the searchlight emitted by all searchlight assemblies 12 can form uniform and stable cross-irradiation on the workpiece.

[0033] Reference Figure 2 In order to ensure the service life and illumination stability of the searchlight bead 122 after long-term use, the cross light source also includes a heat sink 4 and multiple sets of heat-conducting components 5. The heat sink 4 can be a copper plate with high thermal conductivity, and the heat sink 4 is welded to the top wall of the top plate 11. In addition, the outer circumference of the heat sink 4 is the same as that of the top plate 11, and the heat sink 4 extends along the length direction of the top plate 11.

[0034] Reference Figure 2 In the process of the searchlight bead 122 continuously emitting searchlight, the heat sink 4 can quickly discharge the heat generated by the heat sink bead during use, as well as the residual heat on the support plate 121 and the top plate 11, through its own high thermal conductivity, so as to reduce the phenomenon of the searchlight bead 122 aging and affecting normal use in a high temperature environment.

[0035] Reference Figure 2 In this embodiment, the number of the heat conducting components 5 can be three groups. The three groups of heat conducting components 5 are spaced and evenly distributed on the top wall of the top plate 11 along the length direction of the top plate 11, so as to quickly conduct the heat conducted by the heat dissipation plate 4 to the outside through the top opening of the maintenance bracket 2.

[0036] Reference Figure 2Each group of heat-conducting components 5 includes a heat-dissipating fan 51 and a plurality of support rods 52, wherein the support rods 52 can be copper rods, and the number of the support rods 52 can be four. The heat-conducting fan can be a rectangular fan with its own power supply, and the screw support rods 52 are vertically welded at the four corners of the bottom wall of the heat-conducting fan. One end of the screw rod away from the heat-conducting fan is vertically welded to the top wall of the heat dissipation plate 4, so that the heat-conducting fan is stably mounted above the heat dissipation plate 4 to discharge the heat in the maintenance bracket 2 outward through the top opening of the maintenance bracket 2.

[0037] Reference Figure 2 In order to ensure the illumination effect of the searchlight assembly 12 on the workpiece, the searchlight mechanism 1 also includes a light shielding plate 13. In this embodiment, the light shielding plate 13 can be a solid steel plate that is opaque. The number of light shielding plates 13 can be two, and the two light shielding plates 13 are symmetrically welded on both sides of the width direction of the top plate 11 along the vertical direction.

[0038] Reference Figure 2 All searchlight beads 122 are located in the area formed by the two end plates and two light-shielding plates 13 in the length direction of the maintenance bracket 2. The searchlight emitted by the searchlight beads 122 can be emitted downward from between the two light-shielding plates 13, thereby effectively reducing the phenomenon of searchlight scattering to both sides of the width direction of the top plate 11, thereby ensuring the searchlight effect of the searchlight beads 122 on the workpiece.

[0039] Reference Figure 2 The focusing mechanism 3 includes an acrylic focusing column 31 and an acrylic light homogenizing plate 32. In this embodiment, the acrylic focusing column 31 and the acrylic light homogenizing plate are both transparent. The acrylic focusing column 31 is inserted and fixed in the side wall of the maintenance bracket 2 in the horizontal direction. The acrylic focusing column 31 extends along the length direction of the top plate 11. In addition, there is a gap between all the support plates 121 and the acrylic focusing column 31, and all the searchlight beads 122 are located directly above the acrylic focusing column 31.

[0040] Reference Figure 2 The outer circumference of the acrylic light homogenizing plate 32 is the same as that of the acrylic focusing column 31. The acrylic light homogenizing plate 32 is also inserted and fixed in the side wall of the maintenance bracket 2, and the acrylic light homogenizing plate 32 is located below the acrylic focusing column 31. All searchlights emitted downward by the searchlight beads 122 can be absorbed by the acrylic focusing column 31, and the acrylic focusing column 31 then absorbs all the searchlights and gathers them. The gathered searchlight can have higher brightness. After that, the gathered searchlight passes through the acrylic focusing column 31 and reaches the acrylic light homogenizing plate 32. The acrylic light homogenizing plate 32 can evenly distribute the gathered searchlight on the workpiece, thereby helping to reduce the phenomenon of partial over-brightness or over-darkness of the workpiece after being illuminated by the searchlight, and ensuring the brightness, uniformity and stability of the searchlight beads 122 for the workpiece.

[0041] The implementation principle of a cross light source in an embodiment of the present application is: after the searchlight bead 122 emits a searchlight on the inclined support plate 121, the searchlights of adjacent searchlight beads 122 can cross-irradiate on the workpiece, and the searchlights emitted by adjacent searchlight components 12 can also cross-irradiate, thereby achieving the effect of shadowless searchlighting on the workpiece.

[0042] The searchlights emitted by all the searchlight beads 122 are collected by the acrylic focusing column 31 and then evenly distributed on the workpiece through the acrylic light homogenizing plate 32, thereby helping to reduce the phenomenon of partial over-brightness or over-darkness of the workpiece after being illuminated by the searchlight, thereby ensuring the brightness uniformity and stability of the cross-light source for the workpiece.

[0043] The present application also discloses a shadowless searchlight mechanism 1, referring to Figure 5-Figure 7 .

[0044] Reference Figure 5 The shadowless searchlight mechanism 1 includes an external adjustment mechanism 6 and a plurality of groups of cross light sources mentioned above. Among them, all cross light sources are installed in the external adjustment mechanism 6, and the searchlight is uniformly emitted outward through the external adjustment mechanism 6. In this embodiment, the number of cross light sources installed in the external adjustment mechanism 6 can be two groups.

[0045] Reference Figure 5 and Figure 6 The external adjustment mechanism 6 includes an outer box 7 and an adjustment component 8, wherein the outer box 7 can be a rectangular box made of steel plate. Each group of cross light sources is installed in the outer box 7 with an adjustable angle through the adjustment component 8. In this embodiment, the two groups of cross light sources are distributed in a V shape. The bottom wall of the outer box 7 is vertically penetrated with a light guide channel 71, and the light guide channel 71 can allow the searchlights of the two groups of cross light sources to pass through at the same time in a cross searchlighting manner.

[0046] Reference Figure 6 It should be noted that, in order to ensure that the searchlight beads 122 can be used stably for a long time, a plurality of heat dissipation channels 72 are also provided on the side wall of the outer box 7. In this embodiment, the heat dissipation channels 72 are respectively located on the side walls of the outer box 7 in the width direction, and all the heat dissipation channels 72 located on the same side of the outer box 7 in the width direction are spaced and equidistantly distributed along the length direction of the outer box 7.

[0047] Reference Figure 7The direction adjustment component 8 is used to adjust the inclination angle of the cross light source in the outer box 7, and then adjust the cross range of the searchlight emitted by the two groups of cross light sources. In this embodiment, each group of cross light sources has two groups of direction adjustment components 8 at both ends of its length direction, and each group of direction adjustment components 8 includes a connecting screw 81, a contact ring plate 82 integrally formed on the outer peripheral wall of the connecting screw 81, and an operating knob 83 welded to one end of the connecting screw 81 in the length direction and close to the contact ring plate 82. In addition, the outer circumference of the operating knob 83 is larger than the outer diameter of the connecting screw 81.

[0048] Reference Figure 7 The side wall of the outer box 7 is provided with an arc-shaped direction adjustment channel 73, and two groups of direction adjustment components 8 can pass through one group of direction adjustment channels 73. After the end of the connecting screw 81 away from the operating knob 83 passes through the direction adjustment channel 73, it is threadedly connected to the side wall of the maintenance bracket 2, and the end of the connecting screw 81 close to the maintenance bracket 2 is always threadedly connected to the maintenance bracket 2.

[0049] Reference Figure 7 , the operating knob 83 is used for the operator to grasp and twist to rotate the connecting screw 81. After the operator rotates the connecting screw 81 in the counterclockwise direction, the abutment ring plate 82 can keep a distance from the outer box 7 outside the outer box 7, that is, there is a gap between the abutment ring plate 82 and the outer box 7. At this time, the four connecting screws 81 are overlapped on the outer box 7 in pairs, and the cross light source is stably installed in the outer box 7; and the operator can move the connecting screw 81 along the extension direction of the adjustment channel 73 to change the inclination angle of the cross light source and the distance between the two groups of cross light sources, thereby adjusting the cross range of the searchlight emitted by the two groups of cross light sources.

[0050] Reference Figure 7 After the operator rotates the connecting screw 81 in the clockwise direction, the abutment ring plate 82 can be pressed against the outer wall of the outer box 7. At this time, the connecting screw 81 is positioned in the adjustment channel 73 and cannot move, and the cross light source is stably positioned in the outer box 7 to stably illuminate the workpiece.

[0051] The implementation principle of the shadowless searchlight mechanism 1 of the embodiment of the present application is that all cross light sources form cross-irradiated searchlight on the workpiece through the light guide channel 71. The operator can move the connecting screw 81 in the direction adjustment channel 73 to adjust the inclination angle of the cross light source and the distance between the two groups of cross light sources, thereby adjusting the cross range of the searchlight emitted by the two groups of cross light sources.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
