DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] like Figure 1-Figure 9As shown, a flexible circuit board detection device described in an embodiment of the present invention includes a body 1, a clamp 2 and a monitor 3, wherein the clamp 2 is used to clamp the circuit board, and the monitor 3 is used to photograph the circuit board and compare the photographed circuit board photo with a standard circuit board photo to detect the circuit board, and also includes: a frame No. 1 4 fixedly mounted on the body 1, and a slide plate 11 is fixedly mounted on both sides of the frame No. 1 4; two connecting plates 5 symmetrically mounted on the slide plate 11; two slide plates 6 symmetrically and slidably mounted on the connecting plate 5, and the clamp 2 is slidably connected to the slide plate 6.

[0035] Specifically, the monitor 3 uses an existing industrial camera. The existing device uses the monitor 3 to capture the surface details of the circuit board in real time, and uses image processing algorithm analysis to accurately identify tiny defects to achieve the purpose of detection. However, for cracks on the circuit board, or problems such as loose welding and pasting, the detection effect is limited;

[0036] When in use, the operator places the circuit board in the clamping jaws 2, at which time the circuit board is in a straightened state, controls the monitor 3 to start, takes photos of the circuit board for detection, and then controls the clamping jaws 2 on the left and right sides to slide left and right relative to the slide plate 6 and approach each other, so that the flexible circuit board is bent. The monitor 3 simultaneously captures the detailed changes of the circuit board and the accessories connected thereto during the bending process, and through algorithm analysis, determines whether there are defects. Then, the clamping jaws 2 are controlled to reset, and the slide plate 6 is controlled to slide forward and backward relative to the connecting plate 5, driving the clamping jaws 2 to slide synchronously, so that the circuit board is bent again. The monitor 3 simultaneously captures the detailed changes of the circuit board and the accessories connected thereto during the bending process, and through algorithm analysis, determines whether there are defects. After the detection is completed, the clamping jaws 2 are controlled to reset and release the circuit board, flip the circuit board, and the clamping jaws 2 clamp the circuit board, and detect the other side of the circuit board. After the detection is completed, the operator can take out the circuit board after the detection is completed; by setting the slide plate 6, the circuit board can be bent in the front and back directions and left and right and upward, so that the cracks on the circuit board can be more clearly exposed. For components that are not firmly welded or pasted, warping and other phenomena may occur during bending. The monitor 3 can capture these subtle changes, thereby improving the accuracy and comprehensiveness of the detection and ensuring product quality.

[0037] like Figure 6 and Figure 7As shown, it also includes an auxiliary component 7, which includes: a No. 1 spring 71 installed between the two slides 6; a No. 2 spring 72 installed between the clamp 2 and the slide 6; two sliders 73 symmetrically and slidably installed on the slide plate 11, a slide rail 74 is installed between the two sliders 73, a mounting plate 12 is slidably installed on the slide rail 74, and the monitor 3 is installed on the mounting plate 12; a round rod 75 slidably installed on the slide plate 11, and the round rod 75 and the monitor 3 are respectively located on the upper and lower sides of the circuit board.

[0038] Specifically, during detection, the movement of the slider 73 drives the round rod 75 to move left and right synchronously. During the movement, the round rod 75 contacts the surface of the circuit board and pushes the circuit board to bend upward at the contact position with the round rod 75. At this time, the left and right clamps 2 move in a direction close to each other, and the No. 2 spring 72 is stretched. After the round rod 75 is no longer in contact with the circuit board, the clamp 2 returns to its original position under the action of the elastic force of the No. 2 spring 72, and the circuit board is straightened again. By setting the round rod 75, each position of the circuit board can be bent upward to the highest point in the front and back. When it is at the highest point, the shooting of problems such as cracks and warping can be clearer, thereby ensuring that every detail can be captured by the monitor 3, further improving the precision and coverage of the detection, and ensuring the stability and reliability of product quality.

[0039] like Figure 2 and Fig. 9 As shown, the auxiliary component 7 also includes: a blower 76 fixedly installed in the body 1; and a cavity 715 opened in the round rod 75.

[0040] Specifically, before testing, the blower 76 is connected to the cavity 715. During testing, wind is discharged from the cavity 715 of the round rod 75, and the slider 73 is controlled to slide left and right, driving the round rod 75 to slide left and right synchronously. During the sliding process, the airflow acts on the surface of the circuit board to bend the circuit board. Compared with direct contact between the round rod 75 and the circuit board, this method can avoid mechanical damage to the circuit board during the testing process, and the use of airflow blowing can remove dust and impurities on the circuit board, thereby improving the accuracy of the test.

[0041] like Figure 2 , Figure 8 and Fig. 9 As shown, the auxiliary component 7 also includes: an air outlet pipe 714 slidably installed in the cavity 715, the air outlet pipe 714 is connected to the blower 76, and the length of the air outlet pipe 714 is less than the width of the circuit board; a screw rod 77 that drives the air outlet pipe 714 to slide in the cavity 715, and the screw rod 77 is threadedly connected to the air outlet pipe 714.

[0042] Specifically, the screw rod 77 adopts a reciprocating structure. The screw rod 77 rotates two circles, and the air outlet pipe 714 can move back and forth once. During the detection, the screw rod 77 is controlled to rotate so that the air outlet pipe 714 moves back and forth. During the movement of the air outlet pipe 714, the surface of the circuit board is blown to make the circuit board bend. Since the length of the air outlet pipe 714 is less than the width of the circuit board, the circuit board is bent into a hill shape with a high middle and low surroundings. During the process of the circuit board bulging, the clamping claws 2 on the left and right sides approach each other, and the slides 6 on the front and rear sides approach each other, so that the first spring 71 is compressed, and the second spring 72 is stretched. After the air outlet pipe 714 slides forward or backward once, the slide plate 6 is controlled to slide left or right to detect another position of the circuit board, and this cycle is repeated until the airflow from the air outlet pipe 714 no longer acts on the circuit board, that is, all detections are completed, and the clamping jaws 2 and the slide plate 6 return to their original positions under the action of the elastic forces of the first spring 71 and the second spring 72; by setting the air outlet pipe 714 with a length smaller than the width of the circuit board, so that the circuit board forms a hill shape when bent, cracks of various shapes can be clearly shown.

[0043] like Figure 1 and Figure 2 As shown, it also includes a second frame 8 slidably installed on the body 1. After the second frame 8 contacts the first frame 4, a closed space can be formed. The second frame 8 and the first frame 4 are both equipped with lighting lamps, and exhaust ducts 9 are installed on both sides of the second frame 8 and the first frame 4.

[0044] Specifically, the detection is easily affected by the light in the working environment. For example, when the light is too weak, the image information of the circuit board cannot be effectively collected; or when the light is too strong or the light directly shines on the circuit board and produces strong light reflection, the camera of the detection equipment cannot clearly collect the image information of the circuit board. By setting the second frame 8, the light intensity in the detection area is consistent during detection, which improves the above-mentioned problem. By setting the exhaust duct 9, the airflow acting on the circuit board is discharged to avoid secondary pollution of dust and impurities, thereby ensuring the clarity and accuracy of image acquisition and improving the detection efficiency and the credibility of the results.

[0045] like Figure 3 and Figure 4 As shown, the body 1 contains two groups of the auxiliary components 7, and the two groups of the auxiliary components 7 are respectively located on the first frame 4 and the second frame 8 components. The round rods 75 of the two groups of the auxiliary components 7 are distributed obliquely symmetrically with respect to the circuit board, and the round rods 75 of the auxiliary components 7 are all installed between the sliders 73 of the other group of the auxiliary components 7.

[0046] Specifically, by providing two symmetrical groups of auxiliary components 7, during detection, the upper and lower groups can work simultaneously, thereby improving detection efficiency.

[0047] like Figure 3 and Figure 8 As shown, the auxiliary component 7 further includes two push plates 78 fixedly mounted on the air outlet pipe 714 , and the two push plates 78 are respectively located on both sides of the mounting plate 12 .

[0048] Specifically, by providing the push plate 78 , the monitor 3 can move forward and backward and at the same time, the air outlet duct 714 can be driven to move forward and backward synchronously through the push plate 78 .

[0049] like Figure 8 As shown, the auxiliary assembly 7 further comprises: a first gear 79 rotatably mounted on the round rod 75;

[0050] A No. 2 gear 710 drives the No. 1 gear 79 to intermittently rotate, and the No. 2 gear 710 is an incomplete gear. The No. 2 gear 710 is meshed and connected with the No. 1 gear 79, and the No. 2 gear 710 is fixedly connected to the screw rod 77; a No. 1 rack plate 711 is fixedly mounted on the slide plate 11, and the No. 1 rack plate 711 is meshed and connected with the No. 1 gear 79.

[0051] Specifically, when the push plate 78 drives the air outlet duct 714 to move back and forth, the screw rod 77 rotates, driving the second gear 710 to rotate synchronously. The rotation of the second gear 710 drives the first gear 79 to rotate. Since the first gear 79 is meshed with the first rack plate 711, the first gear 79 rotates and slides left and right, driving the slider 73 to move synchronously, so that the air outlet duct 714 and the monitor 3 move, so that after the monitor 3 and the air outlet duct 714 move forward and backward upward once, the monitor 3 and the air outlet duct 714 move a certain distance left and right upward.

[0052] like Figure 6 As shown, the auxiliary component 7 also includes: a connecting block 712 slidably mounted on the slide plate 11, a mirror plate 713 is mounted on the connecting block 712, and the mirror plate 713 is used to illuminate the circuit board. The lens of the monitor 3 is tilted upward and can take pictures of the circuit board in the mirror plate 713 for detection.

[0053] Specifically, by setting the mirror plate 713, the monitor 3 can be located above the round rod 75 with the lens facing upward, thereby improving the problem that when the airflow flowing out of the air outlet duct 714 acts on the circuit board, dust and the like are blown onto the lens due to the reaction force, and the lens is scratched after wiping and cleaning for a long time.

[0054] like Fig. 9As shown, a baffle 10 is rotatably mounted on the round rod 75, and the baffle 10 is used to limit the wind coming out of the air outlet pipe 714 from blowing obliquely relative to the circuit board. The rotation of the baffle 10 can change the wind direction. The slider 73 is rotatably connected to the slide rail 74, and the mirror plate 713 is rotatably connected to the connecting block 712.

[0055] Specifically, by setting the baffle 10, the blown wind is inclined relative to the circuit board, which makes it easier for the airflow to blow away dust and debris on the circuit board. At the same time, for some components that are not firmly welded or pasted, the inclined wind can separate the components from the circuit board, further improving the ability of the equipment to identify defective circuit boards.

[0056] Working principle: before working, the blower 76 is connected to the air outlet pipe 714. When in use, the operator places the circuit board in the clamp 2. At this time, the circuit board is in a straight state, and the monitor 3 is controlled to start. At the same time, the monitor 3 is controlled to move forward and backward to shoot different parts. While the monitor 3 moves forward and backward, it can drive the air outlet pipe 714 to move forward and backward synchronously through the push plate 78. During the movement of the air outlet pipe 714, the surface of the circuit board is blown. Since the length of the air outlet pipe 714 is less than the width of the circuit board, the circuit board is bent into a hill shape with a high middle and low surroundings, which can make cracks of various shapes clearly appear, and the dust and impurities on the circuit board can be removed by using airflow blowing, thereby improving the accuracy of detection. At the same time, for some components that are not firmly welded or pasted, the inclined wind Under the blowing, the components can be separated from the circuit board, further improving the ability of the equipment to distinguish defective circuit boards. When the push plate 78 drives the air outlet pipe 714 to move back and forth, the screw rod 77 rotates, driving the No. 2 gear 710 to rotate synchronously. The rotation of the No. 2 gear 710 drives the No. 1 gear 79 to rotate. Since the No. 1 gear 79 is meshed with the No. 1 rack plate 711, the No. 1 gear 79 rotates and slides left and right, driving the slider 73 to move synchronously, so that the air outlet pipe 714 and the monitor 3 move, so that after the monitor 3 and the air outlet pipe 714 move forward and backward upward once, the monitor 3 and the air outlet pipe 714 move a distance left and right upward to detect another position of the circuit board, and this cycle is repeated until the airflow coming out of the air outlet pipe 714 no longer acts on the circuit board, that is, all detection is completed.

[0057] The above shows and describes the basic principles, main features and advantages of the present invention.
