[0052] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0053] As Figures 1 to 4 shown, the PCB detection device provided by the embodiment of the present utility model includes a camera 100 and a camera adjusting device 200. The camera adjusting device 200 includes a first adjusting plate 1, a first fine-tuning assembly 2 and a clamping assembly 3. The first adjusting plate 1 is provided with a first sliding groove 101. The clamping assembly 3 is provided with a first guiding member 301. The clamping assembly 3 is placed on the first adjusting plate 1, and the first guiding member 301 is slidably placed in the first sliding groove 101. The clamping assembly 3 is used to clamp the camera 100.

[0054] The first fine-tuning assembly 2 is installed on the first adjusting plate 1 and connected to the clamping assembly 3. The first fine-tuning assembly 2 is used to make the clamping assembly 3 rotate around the first rotation axis, or make the clamping assembly 3 move along the first direction y, and the first direction y intersects with the first rotation axis.

[0055] When the clamping assembly 3 rotates about the first rotation axis or moves in the first direction y, the first guide member 301 can slide relative to the first chute 101. Specifically, when the clamping assembly 3 rotates about the first rotation axis in the first rotation direction, the first guide member 301 slides relative to the first chute 101 in the first rotation direction. When the clamping assembly 3 moves linearly in the first direction y, the first guide member 301 slides relative to the first chute 101 in the first direction y.

[0056] The PCB detection device and the camera adjustment device 200 provided by the embodiment of the present invention clamp the camera 100 through the clamping assembly 3. After that, the first fine-tuning assembly 2 can be used to rotate the clamping assembly 3 about the first rotation axis or move it in the first direction y, so as to drive the camera 100 on the clamping assembly 3 to rotate about the first rotation axis or move in the first direction y, so as to adjust the image-taking position of the camera 100 and improve the detection accuracy. In addition, when the clamping assembly 3 rotates about the first rotation axis or moves in the first direction y, since the first guide member 301 of the clamping assembly 3 is slidably disposed in the first chute 101 of the first adjustment plate 1, the sliding fit between the first guide member 301 and the first chute 101 can provide guidance for the rotation of the clamping assembly 3 and prevent the clamping assembly 3 from deflecting.

[0057] In one embodiment, as Figure 4 shown, the first fine-tuning assembly 2 includes a first fine-tuning block 201, a first fastener (not shown in the figure), and a second fastener (not shown in the figure). The first fine-tuning block 201 is installed on the first adjustment plate 1. The first fine-tuning block 201 is provided with a first fastening hole 2011 and a second fastening hole 2012 at intervals in the second direction a. The first fastener is threadedly connected to the first fastening hole 2011 and abuts against the clamping assembly 3, and the second fastener is threadedly connected to the second fastening hole 2012 and abuts against the clamping assembly 3.

[0058] When it is necessary to rotate the clamping assembly 3 about the first rotation axis or move it in the first direction y, the first fastener and the second fastener can be rotated. By adjusting the lengths of the first fastener and the second fastener extending out of the first fine-tuning block 201 respectively, the clamping assembly 3 can be driven to rotate about the first rotation axis, so as to adjust the image-taking position of the camera 100 and improve the detection accuracy. Specifically, when the length of the first fastener extending out of the first fine-tuning block 201 is always the same as the length of the second fastener extending out of the first fine-tuning block 201, the clamping assembly 3 can be moved in the first direction y. When the length of the first fastener extending out of the first fine-tuning block 201 is different from the length of the second fastener extending out of the first fine-tuning block 201, the clamping assembly 3 can be rotated about the first rotation axis.

[0059] The second direction a intersects with the first direction y and the first rotation axis pairwise to ensure that the clamping assembly 3 can rotate around the first rotation axis. In the illustrated embodiment, the second direction a is perpendicular to the first direction y and the first rotation axis.

[0060] In one embodiment, as Figure 2 shown, the clamping assembly 3 includes a clamping bottom plate 302 and a plurality of clamping jaws 303. The clamping bottom plate 302 is placed on the first adjustment plate 1. The first guide member 301 is provided on the clamping bottom plate 302. The plurality of clamping jaws 303 are spaced apart and installed at the edge of the clamping bottom plate 302. The plurality of clamping jaws 303 cooperate with each other to clamp the camera 100, so as to ensure that the clamping assembly 3 can drive the camera 100 to rotate around the first rotation axis.

[0061] In a specific embodiment, the plurality of clamping jaws 303 are respectively arranged on both sides of the clamping bottom plate 302 to clamp the camera 100. It should be noted that Figure 2 only the clamping jaws 303 located on the left side of the clamping bottom plate 302 (the left side in the direction shown in Figure 2 are shown, while the clamping jaws 303 located on the right side of the clamping bottom plate 302 (the right side in the direction shown in Figure 2 are not shown.

[0062] In one embodiment, as Figures 2 to 3 shown, the camera adjustment device 200 further includes a second adjustment plate 4, a third adjustment plate 5, and a second fine adjustment assembly 6. The second adjustment plate 4 is rotatably connected to the third adjustment plate 5 around a second rotation axis. The second fine adjustment assembly 6 is installed on the third adjustment plate 5 and connected to the second adjustment plate 4. The second fine adjustment assembly 6 is used to make the second adjustment plate 4 rotate around the second rotation axis.

[0063] The first adjustment plate 1 is installed on the second adjustment plate 4.

[0064] The second rotation axis intersects with the first rotation axis.

[0065] By making the second adjustment plate 4 rotate around the second rotation axis through the second fine adjustment assembly 6, the first adjustment plate 1, the clamping assembly 3, and the camera 100 can be driven to rotate synchronously around the second rotation axis, so as to adjust the image acquisition position of the camera 100 and improve the detection accuracy. With the cooperation of the first fine adjustment assembly 2 and the second fine adjustment assembly 6, the camera 100 can rotate around two different rotation axes (the first rotation axis and the second rotation axis), further improving the detection accuracy.

[0066] In the illustrated embodiment, the second rotation axis is perpendicular to the first rotation axis and parallel to the first direction y.

[0067] In one embodiment, as Figure 4As shown, the second fine-tuning component 6 includes a second fine-tuning block 601, a third fine-tuning block 602, a third fastener, and a fourth fastener. The second fine-tuning block 601 and the third fine-tuning block 602 are installed on the third adjusting plate 5 at intervals along the third direction b. The second fine-tuning block 601 is provided with a third fastening hole 6011, and the third fine-tuning block 602 is provided with a fourth fastening hole 6021. The third fastener is threadedly connected to the third fastening hole 6011 and abuts against the second adjusting plate 4, and the fourth fastener is threadedly connected to the fourth fastening hole 6021 and abuts against the second adjusting plate 4.

[0068] When it is necessary to rotate the second adjusting plate 4 around the second rotation axis, the third fastener and the fourth fastener can be rotated. By adjusting the length of the third fastener extending from the second fine-tuning block 601 and the length of the fourth fastener extending from the third fine-tuning block 602 respectively, the second adjusting plate 4 can be driven to rotate around the second rotation axis, so as to adjust the image-taking position of the camera 100 and improve the detection accuracy.

[0069] The third direction b intersects the second rotation axis to ensure that the second adjusting plate 4 can rotate around the second rotation axis. In the illustrated embodiment, the third direction b is perpendicular to the second rotation axis, and the third direction b is parallel to the second direction a and the following fifth direction x.

[0070] In one embodiment, the above-mentioned fasteners (the first fastener, the second fastener, the third fastener, and the fourth fastener) are fine-tuning bolts, and the fastening holes (the first fastening hole 2011, the second fastening hole 2012, the third fastening hole 6011, and the fourth fastening hole 6021) are threaded holes to achieve the threaded connection between the two.

[0071] In one embodiment, as Figure 4 shown, a positioning groove 501 is provided on one side of the third adjusting plate 5 facing the second adjusting plate 4, and a positioning hole 401 is provided at a position corresponding to the positioning groove 501 on the second adjusting plate 4.

[0072] The camera adjusting device 200 further includes a rotation positioning block 7. One end of the rotation positioning block 7 is inserted into the positioning groove 501, and the other end of the rotation positioning block 7 is inserted into the positioning hole 401.

[0073] By providing the rotation positioning block 7 between the second adjusting plate 4 and the third adjusting plate 5, the rotation positioning block 7 is rotatably connected to the second adjusting plate 4 and the third adjusting plate 5, or the rotation positioning block 7 is rotatably connected to one of the second adjusting plate 4 and the third adjusting plate 5, so as to realize the rotation positioning between the second adjusting plate 4 and the third adjusting plate 5 and ensure the rotation of the second adjusting plate 4 around the second rotation axis.

[0074] In one embodiment, as Figure 2 and Figure 4 shown, the second adjusting plate 4 is further provided with a rotation limiting hole 402.

[0075] The camera adjustment device 200 further includes a rotation limiting member 8. One end of the rotation limiting member 8 is connected to the third adjustment plate 5, and the other end of the rotation limiting member 8 is received in the rotation limiting hole 402. When the second adjustment plate 4 rotates about the second rotation axis, the rotation limiting hole 402 can move relative to the rotation limiting member 8.

[0076] The rotation limiting hole 402 is a linear elongated hole or an arc-shaped elongated hole. When the rotation limiting hole 402 is a linear elongated hole, the width of the rotation limiting hole 402 should be greater than the maximum width of the cross-section of the rotation limiting member 8 to avoid interfering with the rotation of the second adjustment plate 4. When the rotation limiting hole 402 is an arc-shaped elongated hole, the center of the arc of the rotation limiting hole 402 is located on the second rotation axis to avoid interfering with the rotation of the second adjustment plate 4.

[0077] By providing the rotation limiting hole 402 and the rotation limiting member 8, not only can the rotation of the second adjustment plate 4 be guided, but also the rotation angle of the second adjustment plate 4 can be limited.

[0078] In one embodiment, as Figure 4 shown, the camera adjustment device 200 further includes a fourth adjustment plate 9. The third adjustment plate 5 is slidably connected to the fourth adjustment plate 9 along the fourth direction z.

[0079] The fourth direction z intersects with the second rotation axis. In the illustrated embodiment, the fourth direction z is perpendicular to the second rotation axis and the fourth direction z is perpendicular to the first direction y.

[0080] By slidably connecting the third adjustment plate 5 to the fourth adjustment plate 9 along the fourth direction z, the position of the third adjustment plate 5 can be adjusted along the fourth direction z, and further the positions of the second adjustment plate 4, the first adjustment plate 1, the clamping assembly 3, and the camera 100 in the fourth direction z can be adjusted.

[0081] In one embodiment, as Figure 4 shown, on the side of the fourth adjustment plate 9 facing the third adjustment plate 5, a second sliding groove 901 extending along the fourth direction z is provided. On the side of the third adjustment plate 5 facing the fourth adjustment plate 9, a second guiding member 502 is provided. The second guiding member 502 is slidably connected to the second sliding groove 901, so that the third adjustment plate 5 can be slidably connected to the fourth adjustment plate 9 along the fourth direction z.

[0082] On the side of the fourth adjustment plate 9 facing the third adjustment plate 5, a first sliding positioning block 902 and a second sliding positioning block 903 are further provided. The first sliding positioning block 902 and the second sliding positioning block 903 are respectively arranged at both ends of the second sliding groove 901 along the fourth direction z. The first sliding positioning block 902 and the second sliding positioning block 903 are used to limit the sliding of the second guiding member 502 to limit the maximum displacement of the third adjustment plate 5.

[0083] In one embodiment, as Figure 2 and Figure 4 shown, the third adjusting plate 5 is further provided with a sliding limit hole 503.

[0085] The sliding limit hole 503 is a linear long hole.

[0086] By providing the sliding limit hole 503 and the sliding limit member 10, not only can the sliding of the third adjusting plate 5 be guided, but also the sliding distance of the third adjusting plate 5 can be limited.

[0087] In one embodiment, as Figure 1 and Figure 4 shown, the camera adjusting device 200 further includes a support member 11, and the fourth adjusting plate 9 is slidably connected to the support member 11 along the fifth direction x.

[0088] The fifth direction x intersects with the fourth direction z and the second rotation axis in pairs. In the illustrated embodiment, the fifth direction x is perpendicular to the fourth direction z and the second rotation axis, the fifth direction x is perpendicular to the fourth direction z and the first direction y, and the fifth direction x is parallel to the third direction b.

[0089] By slidably connecting the fourth adjusting plate 9 to the support member 11 along the fifth direction x, the position of the fourth adjusting plate 9 can be adjusted along the fifth direction x, and further the positions of the third adjusting plate 5, the second adjusting plate 4, the first adjusting plate 1, the clamping assembly 3, and the camera 100 in the fifth direction x can be adjusted.

[0092] The sixth direction intersects with the fifth direction x. Specifically, the sixth direction can be perpendicular to the fifth direction x, and the sixth direction is not perpendicular to the fourth direction z.

[0093] The support member 11 is driven by a lifting and lowering component to move in the sixth direction, so that the camera 100 can approach or move away from the detection table, and thus can approach or move away from the workpiece to be measured, and can also adapt to workpieces to be measured with different thicknesses.

[0094] In one embodiment, as Figures 1 to 4 shown, the PCB detection device further includes a heat dissipation member 300 and a lens 400.

The heat dissipation member 300 is used to dissipate heat from the camera 100 to prevent the temperature of the camera 100 from being too high. The camera 100 can take pictures through the lens 400.

[0095] In the PCB detection device provided by the embodiment of the present invention, through the cooperative movement of the first adjustment plate 1, the first fine adjustment component 2 and the clamping component 3, the camera 100 can rotate around the first rotation axis or move in the first direction y; through the cooperative movement of the second adjustment plate 4, the third adjustment plate 5 and the second fine adjustment component 6, the camera 100 can rotate around the second rotation axis; through the cooperative movement of the third adjustment plate 5 and the fourth adjustment plate 9, the camera 100 can move in the fourth direction z; through the cooperative movement of the fourth adjustment plate 9 and the support member 11, the camera 100 can move in the fifth direction x.
