[0002] The Chinese name for PCB is printed circuit board, also known as printed circuit board. After installing various components on the circuit board, it is necessary to spray the PCB with three-proof paint. In the current mainstream PCB production process, optical principles are widely used to detect whether the product has defects in welding and coating.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1 ,as well as Figure 3-Figure 5 The utility model provides a large-viewing-field coating effect detection device, including a frame body 1, a detection mechanism 2 and a conveying mechanism 3. The detection mechanism 2, the conveying mechanism 3 and the electrical operation box 306 are installed inside the frame body 1. The detection mechanism 2 is provided with a high-definition camera 204, an ultraviolet light source 206 and a white light source 209. The top connecting end of the ultraviolet light source 206 is rotatably connected to the ultraviolet light source bracket 205, and the top connecting end of the white light source 209 is rotatably connected to the white light source locking block 208. The side surfaces of the top connecting end of the ultraviolet light source 206 and the side surfaces of the top connecting end of the white light source 209 are both rotatably provided with a first fixing ring and a second fixing ring in a detachable and fixed manner. Ring 212, the first fixing ring and the second fixing ring 212 are both coaxially arranged with the top connecting end of the ultraviolet light source 206, or with the rotation axis of the top connecting end of the white light source 209, a first limiting rod 213 is provided on the side of the first fixing ring, and a second limiting rod 214 is provided on the side of the second fixing ring 212, the ultraviolet light source bracket 205 and the white light source bracket 207 are fixedly connected to the limiting mechanism 210 on the outer side below, and a clamping assembly 211 is provided under the limiting mechanism 210, when the ultraviolet light source 206 and the white light source 209 are rotated and adjusted into place, the first limiting rod 213 is clamped with the clamping assembly 211, or the second limiting rod 214 is clamped with the clamping assembly 211.

[0026] By clamping the first limit rod 213 with the clamping assembly 211, or clamping the second limit rod 214 with the clamping assembly 211, the operator can rotate the ultraviolet light source 206 and the white light source 209 into position very quickly and accurately. When the ultraviolet light source 206 and the white light source 209 are rotated and adjusted to two different positions, they are used to detect PCB boards of two different specifications, which increases the adaptability of the detection field and the light source, and improves production efficiency and detection effect.

[0027] Among them, the first fixing ring and the second fixing ring 212 can be fixed to the side of the top connecting end of the ultraviolet light source 206 or the side of the top connecting end of the white light source 209 by using screws. When the screws are loosened, the first fixing ring and the second fixing ring 212 can be rotated to adjust the angle between the first limiting rod 213 and the second limiting rod 214, thereby being able to adapt to more types of PCB boards.

[0028] Generally, PCB boards are inspected in batches in large quantities. In a short period of time, it is generally only necessary to adjust the angles of the ultraviolet light source 206 and the white light source 209 once or twice, that is, switch the first limit rod 213 and the second limit rod 214 to engage with the clamping assembly 211, corresponding to the processing of two batches of PCB boards of different specifications, and the angle adjustment between the first limit rod 213 and the second limit rod 214 is relatively rare.

[0029] Please refer to Figure 5 In this embodiment, a limiting groove 2101 is provided below the limiting mechanism 210, and the clamping assembly 211 includes a clamping column 2111 vertically telescopically arranged on the inner wall of the limiting groove 2101, and a control block 2112 slidably arranged on the outer surface of the limiting mechanism 210, the control block 2112 is connected to the clamping column 2111, and the first limiting rod 213 and the second limiting rod 214 are both provided with a clamping hole 2131 for clamping with the clamping column 2111. The first limiting rod 213 and the second limiting rod 214 are rotated into the limiting groove 2101 and clamped with the clamping column 2111, which can fix the positions of the ultraviolet light source 206 and the white light source 209. By driving the control block 2112 to move, the clamping connection between the clamping column 2111 and the clamping hole 2131 can be unlocked.

[0030] It is understandable that the clamping column 2111 can be elastically slidably set on the inner wall of the limiting groove 2101 using a spring, and the spring drives the clamping column 2111 to protrude from the inner wall of the limiting groove 2101 to engage with the clamping hole 2131.

[0031] In this embodiment, the first limiting rod 213 is located on the side of the first fixing ring and protrudes toward the second fixing ring 212. The second limiting rod 214 is located on the side of the second fixing ring and protrudes toward the first fixing ring. The rotational paths of the first limiting rod 213 and the second limiting rod 214 overlap so that they can both be engaged with the same clamping assembly 211. The first limiting rod 213 and the second limiting rod 214 can be disassembled and rotated to adjust their angles.

[0032] Please refer to Figure 1 、 Figure 3 and Figure 4 In this embodiment, a camera fixing block 203 is provided above the high-definition camera 204, and the camera fixing block 203 is placed in the camera adapter block 202. One side of the camera adapter block 202 is fixedly connected to the camera mounting plate 201, and the top of the camera mounting plate 201 is fixedly connected to the frame body 1.

[0033] Furthermore, the ultraviolet light source bracket 205 and the white light source bracket 207 are fixedly connected to the upper side walls of the frame body 1, and the white light source bracket 207 is placed below the ultraviolet light source bracket 205, and the high-definition camera 204 is placed above between the ultraviolet light sources 206 on both sides.

[0034] Among them, the ultraviolet light source 206 and the white light source 209 are on both sides of the upper interior of the frame body 1, and the white light source 209 is set below the ultraviolet light source 206. The two light sources adapt to the detection conditions within a certain range. The high-definition camera 204 is set above the middle, which can better increase the field of view for detection.

[0035] Please refer to Figure 2 In this embodiment, a fixed rail 302 and a movable rail 307 are provided in the conveying mechanism 3, and the fixed rail 302 corresponds to the movable rail 307, and there is a distance between them for placing parts.

[0036] Furthermore, a guide rail adjustment assembly 304 is inserted under both the fixed rail 302 and the movable rail 307 , and the outer end of the guide rail adjustment assembly 304 is fixedly connected to the rail operating handle 305 .

[0037] Furthermore, a sprocket 308 is provided above the other end of the guide rail adjustment component 304, and a motor 310 is installed inside the lower side of the sprocket 308. The motor 310 is fixedly connected to a motor fixing plate 309 on the outside, and the upper part of the motor fixing plate 309 is placed on the frame body 1.

[0038] Furthermore, a stop plate assembly 303 is provided in the middle of the fixed track 302 , and a plate sensor 301 is provided above the middle of the fixed track 302 .

[0039] Among them, after the target PCB board completes the coating process, it flows into the conveying mechanism 3 of this coating effect detection equipment through the sprocket 308. As it flows with the sprocket 308, when it enters the set detection position, the board sensor 301 will capture its position information, and then the board stop component 303 will stop the board under program control to stop the PCB board at the set position. At this time, the program controls the motor 310 to stop, and then the flow of the sprocket 308 stops, and the PCB board to be detected is in place.

[0040] Please refer to Figure 1 In this embodiment, the operation warning light 101 is fixedly connected to one side of the upper part of the frame body 1.

[0041] Working principle:

[0042] Corresponding to two batches of PCB boards of different specifications, the angle between the first limiting rod 213 and the second limiting rod 214 is adjusted by loosening the screws of the first fixing ring 212 and rotating the first fixing ring 212. The positions of the two angles correspond to the two batches of PCB boards of different specifications. The control block 2112 is operated to unlock the engagement between the clamping column 2111 and the clamping hole 2131. Then, according to actual inspection requirements, the first limiting rod 213 is rotated and switched to engage with the clamping assembly 211, or the second limiting rod 214 is switched to engage with the clamping assembly 211. In this way, the operator can quickly and accurately rotate and adjust the ultraviolet light source 206 and the white light source 209 into position, and cooperate with the high-definition camera 204 to perform shooting inspection, thereby increasing the adaptability of the inspection field and the light source, and improving production efficiency and inspection effect.

[0043] In addition, the ultraviolet light source 206 and the white light source 209 provide the high-definition camera 204 with the light required for detection, so that the high-definition camera 204 can clearly record the image of the PCB board at this time and compare it with the image of good products in the library, and finally determine whether the coating effect of the PCB board meets the standard. If the coating effect of the PCB board meets the standard, the program will control the stop plate assembly 303 to release it, and the motor 310 will rotate again. Then the sprocket 308 driven by the motor 310 carries the PCB board with qualified coating effect to the equipment of the next process. If the coating effect is unqualified, the equipment will prompt the operator to carry out the defective product processing process.
