Description

Technical Field

[0001] This utility model relates to the field of PCB board testing technology, and in particular to a PCB board adhesive coating testing device. Background Technology

[0002] Circuit boards are also known as printed circuit boards (PCBs), aluminum-based boards, high-frequency boards, thick copper boards, impedance boards, etc. Circuit boards miniaturize and simplify circuits, playing a crucial role in the mass production of fixed circuits and optimizing the layout of electrical appliances.

[0003] After the PCB circuit board is manufactured, it needs to be inspected by testing equipment to check its operating status and the adhesive coating on the board surface. Most of the adhesive coating inspection is done manually, only checking the coverage of the adhesive coating and rejecting some PCB circuit boards with adhesive coating problems. However, these PCB circuit boards rejected due to unqualified adhesive coating can be used normally after mechanical re-adhesion. Since there are a large number of PCB circuit boards after inspection, and the adhesive coating points of each problematic PCB circuit board are different, subsequent repair is quite troublesome. By adding a marking device to the testing device, the range of adhesive coating problem points on the circuit board can be roughly marked, so as to facilitate the quick location of the problem during later repair. Therefore, this application proposes a PCB board adhesive coating inspection device. Summary of the Invention

[0004] The purpose of this invention is to address the problem in the background technology where a large number of PCBs are detected, but the glue application points of each problematic PCB are different, making subsequent repairs quite troublesome. By adding a marking device to the detection device to roughly mark the range of glue application problem points on the PCB, it is possible to quickly locate the problem during later repairs. Therefore, a PCB glue application detection device is proposed.

[0005] The technical solution of this utility model is as follows: a PCB board adhesive coating inspection device, including an inspection table, on which five sets of marking mechanisms for marking PCB boards are provided, each marking mechanism including a marking head for marking and a lamp head for distinguishing areas.

[0006] Optionally, the marking mechanism includes a first support plate with a limiting post that moves through it. One end of the limiting post is fixedly connected to the detection table, and a compression spring is sleeved on the outer circumferential surface of the limiting post. One end of the compression spring contacts the detection table, and the other end of the compression spring contacts the first support plate.

[0007] Optionally, a vertical plate is fixedly connected to the first support horizontal plate, and a pressing plate is fixedly connected to the vertical plate. The surface of the pressing plate is coated with pigment.

[0008] Optionally, the first support plate has a mounting hole, on which a marking head is fixedly mounted. A fixing block is fixedly connected to the first support plate, and a threaded hole is provided on the fixing block. A screw is threaded into the threaded hole, and a pressing block is fixedly connected to one end of the screw. The surface of the pressing block is arc-shaped and contacts the outer peripheral surface of the marking head.

[0009] Optionally, a connecting block is fixedly connected to the first support plate, and a lamp head is installed on the connecting block. The light spot emitted by the lamp head has the same color as the color corresponding to the pressing plate.

[0010] Optionally, a right-angle plate is fixedly connected to the testing table, and a placement slot is provided on the testing table. A high-definition camera is fixedly installed on the right-angle plate, and a support plate is fixedly connected to the right-angle plate. A second support plate is fixedly connected to the support plate, and a support column is in contact with one side of the second support plate. A limit block is fixedly connected to the second support plate, and the limit block slides in a groove on the third support plate.

[0011] Optionally, a rotating block is fixedly connected to the third support plate. The rotating block has a hole and a stud is movably inserted through it. The stud is threaded into a threaded hole on the hinge seat. A display is fixedly installed on the hinge seat. The display is telecom connected to a high-definition camera. Two sets of support legs are fixedly connected to the testing platform.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] A high-definition camera captures images of the PCB board, magnifying and displaying the glue coating on the monitor for clearer images. Based on the monitor's image, the PCB board pillars placed in the mounting slot are adjusted. When a problem occurs, the monitor identifies the affected area and locates the light spot emitted by the nearest lamp. The color of the light spot is then used to press a pressure plate, causing the vertical plate and the first support plate to move downwards. This moves the marking head downwards, bringing one end of the marking head into contact with the PCB board and leaving a mark. This facilitates quick location of the problem during later repairs.

Detailed Implementation

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] like Figure 1 As shown, the present invention proposes a PCB board adhesive coating inspection device, including an inspection table 1. The inspection table 1 is equipped with five sets of marking mechanisms 2 for marking PCB boards. The marking mechanism 2 includes a marking head 206 for marking, which is used to leave a mark on the problematic PCB board, so as to facilitate the quick location of the problem during later repair. The marking mechanism 2 also includes a lamp head 211 for distinguishing areas. The lamp head 211 can emit a light spot that stays on the PCB board to be inspected, so as to facilitate the distinction of different positions.

[0021] like Figure 3 As shown, the marking mechanism 2 includes a first support plate 201, through which a limiting post 202 is movably passed. One end of the limiting post 202 is fixedly connected to the detection table 1, and a compression spring 203 is sleeved on the outer peripheral surface of the limiting post 202. One end of the compression spring 203 is in contact with the detection table 1, and the other end of the compression spring 203 is in contact with the first support plate 201. Under the action of the limiting post 202 and the compression spring 203, the first support plate 201 has the function of lifting and lowering.

[0022] like Figure 3 As shown, a vertical plate 204 is fixedly connected to the first support horizontal plate 201, and a pressing plate 205 is fixedly connected to the vertical plate 204. The surface of the pressing plate 205 is coated with pigment, which makes it easy to distinguish different areas and prevents incorrect pressing later.

[0023] like Figure 3As shown, the first support plate 201 has a mounting hole, on which a marking head 206 is fixedly mounted. A fixing block 207 is fixedly connected to the first support plate 201. The fixing block 207 has a threaded hole, on which a screw 208 is threadedly connected. One end of the screw 208 is fixedly connected to a pressing block 209. The surface of the pressing block 209 is arc-shaped and contacts the outer peripheral surface of the marking head 206. By rotating the screw 208, the pressing block 209 is driven to press against the outer surface of the marking head 206, thereby fixing the marking head 206.

[0024] like Figure 3 As shown, a connecting block 210 is fixedly connected to the first support plate 201, and a lamp head 211 is installed on the connecting block 210. The light spot emitted by the lamp head 211 has the same color as the color corresponding to the pressing plate 205. The light spot emitted by the lamp head 211 can be used to distinguish different areas of the PCB board, thereby facilitating subsequent marking.

[0025] like Figure 2 As shown, a right-angle plate 3 is fixedly connected to the testing table 1. A placement slot 101 is provided on the testing table 1. A high-definition camera 4 is fixedly installed on the right-angle plate 3. A support plate 5 is fixedly connected to the right-angle plate 3. A second support horizontal plate 6 is fixedly connected to the support plate 5. One side of the second support horizontal plate 6 contacts a support column 7. A limit block 8 is fixedly connected to the second support horizontal plate 6. The limit block 8 slides in a groove on the third support horizontal plate 9. Under the action of the second support horizontal plate 6, the limit block 8, and the third support horizontal plate 9, the third support horizontal plate 9 has the function of telescopic extension.

[0026] like Figure 2 As shown, a rotating block 10 is fixedly connected to the third support plate 9. The rotating block 10 has a hole and a stud 11 is movably passed through it. The stud 11 is threaded into the threaded hole on the hinge seat 12. A display 13 is fixedly installed on the hinge seat 12. The display 13 is electrically connected to the high-definition camera 4. Two sets of support legs 14 are fixedly connected to the detection table 1. By adjusting the tightness of the stud 11, the tilt angle of the hinge seat 12 can be changed, thereby changing the tilt angle of the display 13.

[0027] In this embodiment, the PCB board to be tested is placed on the testing table 1 with a placement slot 101. At this time, the high-definition camera 4 will take pictures of the PCB board, thereby capturing and magnifying the image of the adhesive on the PCB board and displaying it on the display 13, making the adhesive on the PCB board clearer. Then, based on the PCB board image captured by the display 13, the PCB board pillar placed on the placement slot 101 is adjusted, and then observed on the display 13. When there is a problem with the PCB board pillar, by observing the area of ​​the problem location on the PCB board on the display 13, the light spot emitted by the lamp head 211 closest to the problem point is found. Then, based on the color of the light spot, the pressing plate 205 is pressed, thereby driving the vertical plate 204 and the first support horizontal plate 201 to move downward, thereby driving the marking head 206 to move downward, so that one end of the marking head 206 contacts the PCB board, thereby leaving a mark, which facilitates the quick location of the problem during later repair.

[0028] The above specific embodiments are merely several preferred embodiments of this utility model.
