The placement area 21 is formed between the plurality of clamping members 24, wherein the first direction, the second direction and the third direction intersect each other.

[0035] In this embodiment, a first slider may be provided at the bottom end of the mounting frame 22, so that the mounting frame 22 can be movably disposed on the first slide rail through the first slider, so that the mounting frame 22 can be movably disposed on the machine 1 along the third direction, thereby facilitating the placement and removal of the circuit board.

According to the size of the circuit board, the user may rotate the positioning member to the side close to the placement area 21, so that the placement area 21 is formed by the plurality of positioning members cooperating with the plurality of clamping members 24, so that the plurality of positioning members cooperating with the plurality of clamping members 24 further divides the placement area 21, and thus it is more convenient to adjust the area range of the placement area 21.

[0037] like Figure 2 As shown, the clamping member 24 includes a first clamping member 241 and a second clamping member 242, the first clamping member 241 includes a first clamping portion 2411 and a first connecting portion 2412 connected to each other, the first clamping member 241 is provided on both sides of the mounting frame 22 along the first direction, the second clamping member 242 is located on one side of the first clamping member 241, the second clamping member 242 includes a second clamping portion 2421, the placement area 21 is formed between the two first clamping portions 2411 and the second clamping portion 2421, and the first connecting portion 2412 has an adjustment hole 2413 for adjusting the distance between the first clamping portion 2411 and the second clamping portion 2421 along the third direction.

In order to further facilitate the adjustment of the size of the placement area 21, the first connecting portion 2412 is provided with a runway-shaped adjustment hole 2413 extending along the third direction, and the relative distance between the two first connecting portions 2412 and the second clamping member 242 is adjusted, thereby adjusting the size of the placement area 21, so that the placement area 21 is more suitable for a hard board or a soft board carried by a carrier to be placed on the measuring table 2.

[0039] like Figure 2 and Figure 3As shown, the clamping end of the first clamping portion 2411 has a first positioning notch 2414, and the clamping end of the second clamping portion 2421 has a second positioning notch. The first positioning notch 2414 and the second positioning notch are mirror-imaged along the first direction, and the inner walls of the first positioning notch 2414 and the second positioning notch both have a plurality of protrusions 2422 for abutting the circuit board.

[0041] like Figure 4 As shown, the detection device also includes a telecentric light source 5, which can be movably arranged along the first direction on the side of the machine 1 away from the camera mechanism 4, and the telecentric light source 5 is located below the placement area 21. The telecentric light source 5 and the camera mechanism 4 are arranged opposite to each other along the second direction.

[0042] In this embodiment, the circuit board is illuminated by a telecentric light source 5 to ensure that the pixel accuracy of the cut edge of the circuit board illuminated by the illumination light source is high. The measuring base plate 23 can be made of a transparent material, such as transparent plastic and glass. The machine 1 can have a through groove, which is located directly below the measuring table 2 and the camera mechanism 4. The light source of the telecentric light source 5 can extend into the through groove, thereby making it more convenient for the telecentric light source 5 to illuminate the circuit board.

[0043] like Figure 4 and Figure 5 As shown, the detection device also includes a transmission module 51 and a connecting rope 52, the transmission module 51 is connected to the telecentric light source 5, one end of the connecting rope 52 is connected to the second driving module 32, and the other end of the connecting rope 52 is connected to the transmission module 51, and the transmission module 51 is used to drive the telecentric light source 5 to move when the camera mechanism 4 moves along the first direction.

[0044] In this embodiment, the connecting rope 52 can be set as a steel wire rope, so as to improve the structural strength of the connecting rope 52. In order to further improve the stability of the telecentric light source 5 moving along the first direction, the connecting rope 52 is set to connect the transmission module 51 and the camera mechanism 4 respectively, so that when the camera mechanism 4 moves along the first direction, the telecentric light source 5 is driven to move synchronously through the transmission module 51. By using the connecting rope 52 and the transmission module 51 to replace the driving parts such as the motor, the use cost of the telecentric light source 5 is reduced.

[0045] In this embodiment, the transmission module 51 may include a second fixed seat 511, a third slider 512 and a third slide rail 513, the telecentric light source 5 is installed on the second fixed seat 511, the third slider 512 is arranged on the second fixed seat 511, the third slide rail 513 is arranged on the machine 1, and the third slider 512 is movably arranged on the third slide rail 513, so that the second fixed seat 511 can be movably arranged on the machine 1. The transmission module 51 may also include a plurality of pulleys, and the connecting rope 52 is sleeved on the pulleys so that the connecting rope 52 can move more conveniently on the pulleys. In order to further improve the stability of the connection rope 52 connected to the transmission module 51 and the camera mechanism 4 respectively, the second fixed seat 511 and the second driving module 32 are both provided with a clamping seat 5111, and the clamping seats 5111 on the second fixed seat 511 and the second driving module 32 are respectively connected to one end of the connecting rope 52. When the second driving module 32 moves along the first direction, it drives the connecting rope 52 to move, and then the connecting rope 52 drives the clamping seat 5111 on the second fixing seat 511 and the telecentric light source 5 to move.

[0046] like Figure 1 , Figure 6 and Figure 7 As shown, the camera mechanism 4 includes a point spectrum 41 and a camera 42, and the point spectrum 41 and the camera 42 are arranged in parallel along the first direction on the second driving module 32, and the point spectrum 41 and the camera 42 of two adjacent camera mechanisms 4 are mirror-arranged along the second direction.

[0047] In this embodiment, the detection device also includes a control system electrically connected to the camera mechanism 4, and the camera mechanism 4 can be used to obtain the size parameters of the circuit board to form a first signal, and feed back the first signal to the control system. The control system analyzes the first signal to determine whether the parameters of the circuit board meet the specifications required by the user. The point spectrum 41 can be used to obtain the height characteristics of the circuit board to form a second signal, and feed back the second signal to the control system. The control system can identify the second signal and the first signal to detect the quality of the circuit board product. By setting the point spectrum 41 and the camera 42 in parallel along the second direction, it is more convenient for the point spectrum 41 and the camera 42 to operate independently of each other, thereby improving the detection efficiency of the point spectrum 41 and the camera 42. By setting the point spectrum 41 and the camera 42 of two adjacent camera mechanisms 4 to be mirrored along the second direction, it is more convenient for the two camera mechanisms 4 to detect different circuit boards independently of each other, thereby improving the detection efficiency of at least two camera mechanisms 4.

[0049] In this embodiment, in order to improve the accuracy of the detection of the camera mechanism 4, the camera 42 is set to be a camera 42 that automatically switches the lens. The third drive module 43 may include a third driver and a mounting seat. By setting the mounting seat on the outer side wall of the camera 42, the third driver drives the mounting seat to drive the camera 42 to rotate, thereby making it more convenient for the third drive module 43 to realize the switching of the lens by rotating the camera 42. The camera mechanism 4 can switch different lenses according to different size characteristics of the circuit board, thereby improving the accuracy of the detection of the camera mechanism 4. In order to avoid external interference with the camera mechanism 4, a protective cover is set on the periphery of the point spectrum 41 and the camera 42, thereby improving the service life of the camera mechanism 4.

[0050] like Figure 6 and Figure 7As shown, the detection device also includes a fourth driving module 6, and the fourth driving module 6 is arranged on the side of the second driving module 32 close to the camera 42.

The fourth driving module 6 is used to drive the ring light source 44 to move along the second direction to adjust the distance between the ring light source 44 and the camera 42.

[0051] In this embodiment, the ring light source 44 is used to provide uniform ring light illumination for the camera 42. The light source irradiated by the ring light source 44 can effectively distinguish various features on the circuit board, such as glue and reflective sheet on the circuit board, so as to avoid the influence of glue and reflective sheet on the shooting of the camera mechanism 4, so that the size features on the circuit board are displayed more clearly. The ring light source 44 can also reduce reflections and shadows on the surface of the circuit board, thereby improving the clarity of the image of the size features of the circuit board taken by the camera 42.

[0052] In this embodiment, a fourth driving module 6 is used to drive the annular light source 44 to move along the second direction, thereby adjusting the height difference between the annular light source 44 and the circuit board, so that the annular light source 44 can illuminate the circuit board from multiple angles, thereby solving the problem that the light source type of the existing detection equipment is single and cannot meet the needs of circuit board detection.

[0053] like Figure 7 As shown, the annular light source 44 includes a lighting portion 441 and a third connecting portion 442 arranged on the side of the lighting portion 441 close to the camera 42, the fourth driving module 6 includes a connecting seat 61 and a first driver 62, the connecting seat 61 is slidably arranged on the second driving module 32 along the second direction, the first driver 62 is drivingly connected to one end of the connecting seat 61, and the other end of the connecting seat 61 is connected to the third connecting portion 442.

[0054] In this embodiment, the lighting part 441 may be an annular cover, and the end surface of the lighting part 441 that emits light may be an arc surface, so as to better converge the light source on the circuit board. The central axis of the lighting part 441 and the central axis of the camera 42 are located on the same straight line along the second direction, so that the shooting range of the camera 42 and the irradiation range of the annular light source 44 at least partially overlap, so that it is more convenient for the lighting part 441 to provide lighting for the camera 42. In order to improve the stability of the connection between the annular light source 44 and the fourth driving module 6, one end of the connecting seat 61 is connected to the third connecting part 442. The first driver 62 is used to drive the connecting seat 61 to reciprocate along the second direction, and the side of the connecting seat 61 away from the annular light source 44 may be provided with a second slider (not shown in the figure), and the second driving module 32 may be provided with a second slide rail (not shown in the figure) matched with the second slider, and the second slide rail is extended along the second direction, and the second slider is movably arranged on the second slide rail, so that the connecting seat 61 is slidably arranged on the second driving module 32 along the second direction, thereby driving the annular light source 44 to move along the second direction.
