[0031] The preferred embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0032] Example 1
[0033] like Figures 1 to 4 As shown, a mechanism for adjusting the position of the focal plane spot of a multi-color module includes a lens group mounting plate 1, a collimating lens group 2, a first adjustment bracket 3, and a second adjustment bracket 4. The collimating lens group 2 includes a base 21, and the two sides of the base 21 are connected to the lens group mounting plate 1 through the first adjustment bracket 3 and the second adjustment bracket 4 respectively.
[0034] An upper and lower positioning adjustment column 31 is provided in the middle of the inner side of the first adjustment bracket 3 and the second adjustment bracket 4, and the upper and lower positioning adjustment grooves 22 are provided on both sides of the base 21 respectively. The upper and lower positioning adjustment columns 31 of the first adjustment bracket 3 and the second adjustment bracket 4 are cooperated and connected with the upper and lower positioning adjustment grooves 22 on both sides of the base 21; the first adjustment bracket 3 and the second adjustment bracket 4 are provided with a through upper and lower adjustment grooves 32, and the upper and lower adjustment grooves 32 are connected to the two sides of the base 21 through upper and lower adjustment screws 33; left and right positioning adjustment grooves 11 are provided on both sides of the lens group mounting plate 1, and left and right positioning adjustment columns 34 are provided on the bottom of the first adjustment bracket 3 and the second adjustment bracket 4 respectively, and the left and right positioning adjustment columns 34 are positioned and cooperated with the left and right positioning adjustment grooves 11.
[0035] Specifically, the first adjustment bracket 3 and the second adjustment bracket 4 are each provided with two upper and lower adjustment slots 32, and two fixed positioning holes 23 are respectively provided on both sides of the base 21. The two fixed positioning holes 23 are respectively located on the upper and lower sides of the upper and lower positioning adjustment slots 22, and the upper and lower adjustment slots 32 are connected to the fixed positioning holes 23 through upper and lower adjustment screws 33.
[0036] Two left and right positioning grooves 35 are provided at the bottom of the first adjustment bracket and the bottom of the second adjustment bracket, and the left and right positioning grooves 35 extend along the horizontal left and right directions; left and right positioning holes 12 are provided on both sides of the lens group mounting plate 1, and the left and right positioning grooves 35 of the first adjustment bracket and the second adjustment bracket are respectively connected to the left and right positioning holes 12 through left and right adjustment screws 36.
[0037] The bottom of the first adjustment bracket has an outwardly protruding step, with the left and right positioning adjustment posts 34 located at the bottom of the step. The left and right positioning slots 35 of the first and second adjustment brackets extend through the steps of the first and second adjustment brackets. Both the first and second adjustment brackets have two left and right positioning slots 35. The left and right positioning holes 12 are located on either side of the left and right positioning adjustment slots 11.
[0038] During assembly, first, install the first adjustment bracket 3 to the left side of the base 21 of the collimating lens group 2. During the assembly process, pay attention to aligning the upper and lower positioning adjustment columns 31 of the first adjustment bracket 3 with the upper and lower positioning adjustment slots 22 on the base 21 of the collimating lens group 2, and then respectively fix the upper and lower adjustment screws 33 through the two upper and lower adjustment slots 32 of the first adjustment bracket 3 and the fixed positioning holes 23 of the collimating lens group 2. Note that the screws cannot be tightened at this time, and must be tightened only after the adjustment of the collimating lens group 2 is completed.
[0039] Secondly, follow the same method as in the previous step to install the second adjustment bracket 4 to the right side of the base 21 of the collimating lens group 2. During the assembly process, pay attention to aligning the upper and lower positioning adjustment columns 31 of the second adjustment bracket 4 with the upper and lower positioning adjustment slots 22 on the base 21 of the collimating lens group 2. Then, respectively, fix the upper and lower adjustment screws 33 through the two upper and lower adjustment slots 32 of the second adjustment bracket 4 and the fixed positioning holes 23 of the collimating lens group 2. Note that the screws cannot be tightened at this time. Wait until the collimating lens group 2 is adjusted before tightening them;
[0040] Then, install the above-assembled parts onto the lens group mounting plate 1. During the assembly process, pay attention to aligning the left and right positioning adjustment columns 34 of the first adjustment bracket 3 and the second adjustment bracket 4 with the left and right positioning adjustment slots 11 of the lens group mounting plate 1. Then, fix the left and right adjusting screws 36 through the left and right positioning slots 35 of the two first adjustment brackets and the left and right positioning holes 12 of the lens group mounting plate 1. Note that the screws cannot be tightened at this time and must be tightened after the collimating lens is adjusted. Then, fix the left and right adjusting screws 36 through the left and right positioning slots 35 of the two second adjustment brackets and the left and right positioning holes 12 of the lens group mounting plate 1. Note that the screws cannot be tightened at this time and must be tightened after the collimating lens group 2 is adjusted.
[0041] Finally, by adjusting the left and right positions of the first adjustment bracket and the second adjustment bracket, the left and right positions of the focal plane spot of the multi-color module light outlet are determined. After the spot position is centered, the left and right adjustment screws 36 are tightened. Finally, by adjusting the position of the collimating lens group 2 up and down, the upper and lower positions of the focal plane spot of the multi-color module light outlet are determined. After the spot position is centered, the upper and lower adjustment screws 33 are tightened, and the adjustment is completed.
[0042] The collimating lens group 2 is an adjustable component. The position of the light spot on the focal plane of the multi-color module is adjusted by moving the collimating lens group 2 up and down and left and right. In addition, for more accurate adjustment, a first adjustment bracket 3 and a second adjustment bracket 4 as well as upper and lower positioning adjustment slots 22 are added on the left and right sides of the collimating lens group 2 to better cooperate with the adjustment brackets on both sides and realize the controllable adjustment of the collimating lens group 2 up and down.
[0043] The lens assembly mounting plate 1 is a supporting part. Left and right positioning adjustment slots 11 of the first adjustment bracket 3 and the second adjustment bracket 4 are added to the lens assembly mounting plate 1 to achieve left and right controllable adjustment of the collimating lens assembly 2.
[0044] The first adjustment bracket 3 and the second adjustment bracket 4 are the main adjustment parts. The vertical and horizontal adjustment of the collimating lens group 2 is realized through the vertical and horizontal adjustment columns 31 and the horizontal and vertical adjustment columns 34 on these two parts. Among them, the vertical and horizontal adjustment columns 31 cooperate with the collimating lens group 2, and the horizontal and vertical adjustment columns 34 cooperate with the lens group mounting plate 1.
[0045] The four left-right adjustment screws 36 of the first and second adjustment brackets 3 and 4 are used to precisely position the collimating lens assembly 2 when it is adjusted left-right, ensuring that the focal plane light plate of the multi-color module is centered and does not move, thus maintaining product stability. The four up-and-down adjustment screws 33 are used to precisely position the collimating lens assembly 2 when it is adjusted up-and-down, ensuring that the focal plane light spot of the multi-color module is centered and does not move, thus maintaining product stability.
[0046] This embodiment achieves greater adjustment of the focal plane spot position of the multi-color module, improves the positioning accuracy of the focal plane spot position of the multi-color module, reduces product quality problems caused by inaccurate spot position, and improves product stability.
