[0037] The following introduces the technical solutions provided by the embodiments of this application in conjunction with the accompanying drawings.

[0038] Refer to Figure 1 As shown, this application provides a detection mechanism 100. The detection mechanism 100 includes a coarse adjustment module 110, a plurality of optical modules 120, and a plurality of fine adjustment modules 130. The detection mechanism 100 is used for multi-point synchronous optical detection of the product to be detected, so as to obtain the chromaticity, color coordinate information, etc. of each detection point of the product to be detected, and ensure the good optical performance of the product to be detected. Among them, in this embodiment, the product to be detected is a display module, and the optical module 120 is used for optical detection of the product to be detected. The optical module 120 can be an optical probe, a camera element, or other optical elements that can obtain the chromaticity, color coordinate information, etc. of the product to be detected.

[0039] The optical module 120 is connected to the coarse adjustment module 110 through the fine adjustment module 130, that is, each of the multiple optical modules 120 is independently configured with a fine adjustment module 130. The coarse adjustment module 110 is used to synchronously adjust the multiple optical modules 120 in the three directions of X, Y, and Z to perform a rough adjustment of the overall positions of the multiple optical modules 120 in a large range. The fine adjustment module 130 is used to adjust the optical module 120 in the three directions of X, Y, and Z. Since each optical module 120 is independently configured with a fine adjustment module 130, the fine adjustment module 130 can independently adjust the optical module 120 in the three directions of X, Y, and Z to perform a fine adjustment of the positions of the multiple optical modules 120 in a small range.

[0040] For the above detection mechanism 100, when the specification dimensions of the product to be detected change, the multiple optical modules 120 are initially adjusted to the positions near each detection point through the coarse adjustment module 110, and the multiple optical modules 120 are independently fine-tuned to the detection positions of each detection point through the multiple fine adjustment modules 130. Through the initial rough adjustment of the coarse adjustment module 110 in cooperation with the independent fine adjustment of the fine adjustment module 130, the adjustment efficiency of the multiple optical modules 120 can be improved, and when the positions of some or all of the detection points shift, the fine adjustment module 130 can independently fine-tune the corresponding optical module 120 to the detection point position after the position change, so that the multiple optical modules 120 can perform multi-point synchronous detection at the corresponding detection points and avoid the bad phenomenon of missing some detection points.

[0041] In one embodiment, refer to Figure 1 、 Figure 2 and Figure 3 As shown, the coarse adjustment module 110 includes a lifting component 111, at least one first X-direction adjustment component 112, and at least one first Y-direction adjustment component 113. The first Y-direction adjustment component 113 is slidably disposed on the lifting component 111 along the Z direction, the first X-direction adjustment component 112 is slidably disposed on the first Y-direction adjustment component 113 along the Y direction, and the multiple optical modules 120 are slidably disposed on the first X-direction adjustment component 112 along the X direction.

[0042] In this way, the first X-direction adjustment component 112 can adjust the positions of multiple optical modules 120 in the X direction. The first Y-direction adjustment component 113 can adjust the position of the first X-direction adjustment component 112 in the Y direction. Since the optical modules 120 are arranged on the first X-direction adjustment component 112, the first Y-direction adjustment component 113 can adjust the positions of multiple optical modules 120 in the Y direction. The lifting component 111 can adjust the position of the first Y-direction adjustment component 113 in the Z direction. Since the optical modules 120 are indirectly arranged on the first Y-direction adjustment component 113 through the first X-direction adjustment component 112, the lifting component 111 can adjust the positions of multiple optical modules 120 in the Z direction. That is to say, through the first X-direction adjustment component 112, the first Y-direction adjustment component 113 and the lifting component 111, the overall position of multiple optical modules 120 can be roughly adjusted in the X, Y, and Z directions.

[0043] Further, continue to refer to Figure 1 and Figure 2 As shown, the lifting component 111 includes a driving module 1111, a carrier plate 1112, and a movable plate 1113. The movable plate 1113 is movably connected to the carrier plate 1112 in the Z direction. The driving module 1111 is in transmission connection with the movable plate 1113. The first Y-direction adjustment component 113 is arranged on the movable plate 1113. When it is necessary to adjust the height (Z-direction position) of multiple optical modules 120, the driving module 1111 outputs power to the movable plate 1113. The movable plate 1113 moves in the Z direction relative to the carrier plate 1112, and drives multiple optical modules 120 to move integrally in the Z direction through the movable plate 1113, so as to adjust the Z-direction positions of multiple optical modules 120.

[0044] Specifically, refer to Figure 1 and Figure 2As shown in the figure, the driving module 1111 includes a hand crank 1114, multiple guide rods 1115, and a lead screw 1116. The lead screw 1116 is connected to the output end of the hand crank 1114. The axial directions of the lead screw 1116 and the guide rods 1115 are both consistent with the Z direction. The end of the lead screw 1116 away from the output end of the hand crank 1114 is screwed onto the movable plate 1113. That is to say, one end of the lead screw 1116 is connected to the output end of the hand crank 1114, and the other end of the lead screw 1116 is screwed onto the movable plate 1113. The guide rods 1115 connect the bearing plate 1112 and the movable plate 1113, and the multiple guide rods 1115 are arranged at intervals along the circumferential direction of the movable plate 1113. Exemplarily, if there are four guide rods 1115, the four guide rods 1115 are respectively located at the four corner positions of the movable plate 1113. The movable plate 1113 can move along the axial direction of the guide rods 1115, that is, the movable plate 1113 can move along the Z direction relative to the bearing plate 1112. The guide rods 1115 can guide the movement of the movable plate 1113 in the Z direction to improve the movement accuracy of the movable plate 1113 driving the multiple optical modules 120 to move towards the Z direction.

[0045] For the above detection mechanism 100, when it is necessary to adjust the heights of the multiple optical modules 120, the operator acts on the hand crank 1114 in ways such as pushing, pulling, and rotating. The hand crank 1114 moves and drives the lead screw 1116 to move. The lead screw 1116 rotates and drives the movable plate 1113 to move along the Z direction on the guide rods 1115. The multiple optical modules 120 are driven by the movable plate 1113 to move integrally towards the Z direction to adjust the Z-direction positions of the multiple optical modules 120.

[0046] Among them, the driving module 1111 is not limited to the above-described component modules of the hand crank 1114, the guide rods 1115, and the lead screw 1116. The driving module 1111 can also be driving elements such as a driving motor and a driving cylinder. The specific element type of the driving module 1111 is not limited in this application. And, in this embodiment, the lifting assembly 111 further includes a first locking member 1117 and a lifting display (not shown in the figure). The lifting display is used to display the overall height position of the multiple optical modules 120. The first locking member 1117 is used to lock the hand crank 1114 to lock the multiple optical modules 120 at the preset height position when the multiple optical modules 120 move to the preset height position, preventing the height position of the multiple optical modules 120 from changing due to the operator accidentally touching the hand crank 1114 and improving the detection reliability of the product to be inspected.

[0047] Further, refer to Figures 1-3As shown in the figure, the first Y-direction adjustment component 113 includes a Y-direction slide rail 1131 and at least one Y-direction slider 1132. The Y-direction slide rail 1131 is arranged on the lifting component 111, and the Y-direction slider 1132 is slidably arranged on the Y-direction slide rail 1131 along the Y direction. The first X-direction adjustment component 112 includes an X-direction slide rail 1121 and at least one X-direction slider 1122. The X-direction slide rail 1121 is arranged on the Y-direction slider 1132. By the sliding of the Y-direction slider 1132 along the Y-direction slide rail 1131, the whole first X-direction adjustment component 112 is driven to slide along the Y direction on the Y-direction slide rail 1131. The X-direction slider 1122 is slidably arranged on the X-direction slide rail 1121 along the X direction. The optical module 120 is connected to the X-direction slider 1122 through the fine adjustment module 130. By the sliding of the X-direction slider 1122 along the X-direction slide rail 1121, the optical module 120 is driven to slide along the X direction on the X-direction slide rail 1121. Since the first X-direction adjustment component 112 can slide along the Y direction on the Y-direction slide rail 1131, the optical module 120 can be driven to slide along the Y direction under the drive of the first X-direction adjustment component 112. In this way, the first X-direction adjustment component 112 and the first Y-direction adjustment component 113 can drive the optical module 120 to move in the XY plane.

[0048] Exemplarily, in this embodiment, there are 9 optical modules 120 and 3 first X-direction adjustment components 112. The first X-direction adjustment component 112 includes 3 X-direction sliders 1122. The 3 X-direction sliders 1122 are arranged at intervals along the X direction on the X-direction slide rail 1121. The 3 first X-direction adjustment components 112 can realize the array connection of the 9 optical modules 120. The 3 first X-direction adjustment components 112 are arranged at intervals along the Y direction. By the first X-direction adjustment component 112, the positions of the 3 optical modules 120 in the Y direction can be synchronously adjusted, which can improve the adjustment flexibility of the optical module 120. Moreover, the first X-direction adjustment component 112 is also locked to the movable plate 1113 through the second locking member 135. When the positions of the optical module 120 in the XY directions are adjusted to the preset positions, the optical module 120 can be locked to the preset positions through the second locking member 135, preventing the horizontal positions of the optical module 120 from changing due to accidental touch by the operator and improving the detection reliability of the product to be detected.

[0049] In one embodiment, refer to Figure 1 、 Figure 4 and Figure 5As shown, the fine adjustment module 130 includes a locking frame 131, a second X-direction adjustment assembly 132, a second Y-direction adjustment assembly 133, and a Z-direction adjustment assembly 134. The locking frame 131 is locked to the coarse adjustment module 110, so that the optical module 120 is connected to the coarse adjustment module 110 through the fine adjustment module 130. The second X-direction adjustment assembly 132 is connected to the locking frame 131, the second Y-direction adjustment assembly 133 is slidably disposed on the second X-direction adjustment assembly 132 along the X direction, the Z-direction adjustment assembly 134 is slidably disposed on the second Y-direction adjustment assembly 133 along the Y direction, and the optical module 120 is slidably disposed on the Z-direction adjustment assembly 134 along the Z direction.

[0050] Thus, the position of the optical module 120 in the Z direction can be adjusted through the Z-direction adjustment component 134, and the position of the Z-direction adjustment component 134 in the Z direction can be adjusted through the second Y-direction adjustment component 133. Since the optical module 120 is arranged on the Z-direction adjustment component 134, the second Y-direction adjustment component 133 can adjust the position of the optical module 120 in the Y direction. The position of the second Y-direction adjustment component 133 in the X direction can be adjusted through the second X-direction adjustment component 132. Since the optical module 120 is indirectly arranged on the second Y-direction adjustment component 133 through the Z-direction adjustment component 134, the second X-direction adjustment component 132 can adjust the position of the optical module 120 in the X direction. That is, the optical module 120 can be fine-tuned independently in the three directions of X, Y, and Z through the second X-direction adjustment component 132, the second Y-direction adjustment component 133, and the Z-direction adjustment component 134.

[0051] Specifically, see Figure 1 , Figure 4 and Figure 5 As shown, the second X-axis adjustment assembly 132 includes an X-axis slide 1321 and an X-axis adjustment rod 1322 that is transmission-connected to the X-axis slide 1321, and the X-axis slide 1321 is disposed on the locking frame 131. The second Y-axis adjustment assembly 133 includes a Y-axis slide 1331 and a Y-axis adjustment rod 1332 that is transmission-connected to the Y-axis slide 1331, and the Y-axis slide 1331 is disposed on the X-axis slide 1321 through a first adapter plate 136. The Z-axis adjustment assembly 134 includes a Z-axis slide 1341 and a Z-axis adjustment rod 1342 that is transmission-connected to the Z-axis slide 1342, and the Z-axis slide 1341 is disposed on the Y-axis slide 1331 through a second adapter plate 137, and the optical module 120 is disposed on the Z-axis slide 1341 through a third adapter plate 138.

[0052] When the above detection mechanism 100 needs to independently fine-tune the position of the optical module 120 in the X, Y, and Z directions, the X-direction adjusting rod 1322 is actuated by means of pushing, pulling, rotating, etc. The X-direction adjusting rod 1322 drives the X-direction sliding table 1321 to move in the X direction to adjust the position of the optical module 120 in the X direction; and the Y-direction adjusting rod 1332 is actuated by means of pushing, pulling, rotating, etc. The Y-direction adjusting rod 1332 drives the Y-direction sliding table 1331 to move in the Y direction to adjust the position of the optical module 120 in the Y direction; and the Z-direction adjusting rod 1342 is actuated by means of pushing, pulling, rotating, etc. The Z-direction adjusting rod drives the Z-direction sliding table 1341 to move in the Z direction to adjust the position of the optical module 120 in the Z direction. The optical module 120 can be independently fine-tuned in the X, Y, and Z directions through the second X-direction adjusting assembly 132, the second Y-direction adjusting assembly 133, and the Z-direction adjusting assembly 134.

[0053] In one embodiment, refer to Figure 1 、 Figure 3 and Figure 6 As shown, the detection mechanism 100 includes multiple groups of optical modules 140. The multiple groups of optical modules 140 are arranged at intervals in the X direction on the first X-direction adjusting assembly 112. The optical module 140 includes multiple optical modules 120. The multiple optical modules 120 in the optical module 140 are arranged at intervals in the Y direction on the first X-direction adjusting assembly 112.

[0054] Exemplarily, in this embodiment, the optical module 140 includes 3 optical modules 120. The 3 optical modules 120 in the optical module 140 are arranged at intervals in the Y direction on the first X-direction adjusting assembly 112. Of course, in other feasible embodiments, the number of optical modules 120 in the optical module 140 can also be 4, 6, or other numbers. The number of optical modules 120 in the optical module 140 is not limited in this application.

[0055] Furthermore, the optical module 140 further includes a guide shaft 141. The guide shaft 141 connects the multiple optical modules 120 in the optical module 140. Since the multiple optical modules 120 in the optical module 140 are connected together by the guide shaft 141, the multiple optical modules 120 in the optical module 140 can be synchronously adjusted in the X-direction position to further improve the adjustment flexibility of the optical module 120.

[0056] In one embodiment, refer to Figure 1 、 Figure 3 and Figure 6As shown, the detection mechanism 100 further includes an indicating member 150. The indicating member 150 is used to indicate the X and Y positions of the optical module 120. When adjusting the XY position of the optical module 120, the indicating member 150 can visualize the XY position where the optical module 120 is located to the operator, facilitating the operator to timely grasp the adjustment position and adjustment amount of the optical module 120, and improving the detection reliability of the product to be detected.

[0057] Among them, in this embodiment, the indicating member 150 is an indicating needle, and a scale table is etched on the movable plate 1113. The position of the scale table is indicated by the indicating member 150 to indicate the X and Y positions of the optical module 120. Of course, in other feasible embodiments, the indicating member 150 can also be an indicating light, a position sensor, etc. The specific element type of the indicating member 150 is not limited in this application.

[0058] The following combines the attached Figures 1-6 A detailed description of the adjustment operation of the optical module 120 in this application is given below.

[0059] When the specification size of the product to be detected changes, causing the overall offset of multiple detection points of the product to be detected, the coarse adjustment module 110 synchronously adjusts multiple optical modules 120 in the X, Y, and Z directions, so that the multiple optical modules 120 are overall offset to near the multiple detection points of the product to be detected. Due to the synchronous adjustment of the multiple optical modules 120, only a single movement is required to overall offset the multiple optical modules 120 to near the multiple detection points, which can improve the adjustment efficiency of the multiple optical modules 120. When some or all of the detection point positions change after the product to be detected is replaced, after the coarse adjustment module 110 overall offsets the multiple optical modules 120 to near the multiple detection points of the product to be detected, the fine adjustment module 130 is used to perform a fine adjustment operation on the corresponding optical module 120 to finely adjust the optical module 120 to the detection position of the corresponding detection point, so that the multiple optical modules 120 can perform multi-point synchronous detection at the corresponding detection points and avoid the bad phenomenon of missing some detection points.

[0060] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0061] The above-described embodiments only express several implementation manners of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of this application, several deformations and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the protection scope of the patent of this application should be subject to the appended claims.
