Description

Technical Field

[0002] Copper plating pretreatment of circuit boards is one of the important steps in making circuit boards. The purpose of pretreatment is to make the surface of the circuit board smoother so that the subsequent copper plating treatment can be more uniform and stable.

[0003] A patent application with publication number CN218014578U discloses a circuit board copper plating pretreatment degreasing machine, which includes a box body and at least two cleaning tanks separated by vertical partitions along the length direction of the box body. After the circuit board is degreased, the residual liquid on the circuit board is blown into the cleaning tank, and the circuit board is then moved to another cleaning tank in the box body, thereby preventing a large amount of liquid from the first degreasing process from falling into the liquid from the second degreasing process, preventing the liquid from the second degreasing process from being contaminated, and ensuring the quality of degreasing.

[0004] Whether oil stains will be generated during use in the above-mentioned prior art depends on multiple factors, including but not limited to the parameter settings during drilling. Therefore, not all circuit board surfaces have oil stains.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0033] Example 1

[0034] like Figures 1 to 7As shown, a circuit board copper plating pretreatment monitoring device described in an embodiment of the present invention includes a main body 1, a fixed shell 3 is fixedly connected to the upper surface of the main body 1, an oil pollution monitoring device 31 is arranged inside the fixed shell 3, a conveyor belt 2 is rotatably arranged inside the main body 1, a fixed plate 4 is fixedly connected to the upper surface of the conveyor belt 2, a fixed frame 4 is fixedly connected to the upper surface of the fixed plate 4, a fixed frame 41 is fixedly connected to the inside of the fixed frame 41, a first rotating rod 43 is rotatably connected, one end of the first rotating rod 43 is fixedly connected to a placement plate 44, a pressure plate 427 is rotatably arranged inside the placement plate 44, and the circuit board can be fixed on the placement plate 44 by rotating the pressure plate 427, a second rotating rod 45 is rotatably connected to one side of the fixed frame 41, the circumferential surfaces of the second rotating rod 45 and the first rotating rod 43 are fixedly connected to pulleys 46, and the two pulleys 46 are connected by belt transmission.

[0035] Specifically, during the production of circuit boards, if the temperature is too high or uneven, the surface of the circuit board steel sheet will become dirty, and in severe cases, the surface of the steel sheet may be oxidized, thereby affecting the performance of electronic components.

[0036] The stains on the surface of the circuit board can be monitored using an oil stain monitoring device 31. The oil stain monitoring device 31 is an automatic optical inspection device. The automatic optical inspection device is a prior art and has been widely used in the fields of circuit boards, semiconductors, etc. Its operation and monitoring steps include configuring an image photographing device and a 3D laser scanning sensor. The image photographing device continuously obtains a scanned image of the object to be inspected, obtains the difference between the scanned image and the current standard image, and performs detection and judgment based on the difference. If the current standard image needs to be updated, the current scanned image is used to update the current standard image to obtain an updated target standard image. During the operation, it should be noted that the optical inspection step is started after the image inspection step is qualified. If the difference is greater than a preset difference threshold, the object to be inspected is determined to be unqualified.

[0037] When the present invention is in use, the oil pollution monitoring device 31 is turned on, and the circuit board material is placed between the two placement plates 44. After the placement is completed, the conveyor belt 2 can be driven to rotate intermittently, and the conveyor belt 2 rotates and drives the fixed plate 4 to move, and the fixed plate 4 drives the fixed frame 41 to move, and the fixed frame 41 drives the first rotating rod 43 to move synchronously, and the first rotating rod 43 drives the placement plate 44 to move synchronously, and the placement plate 44 can drive the circuit board to move to the bottom of the oil pollution monitoring device 31, and drive the pressure plate 427 to rotate. The rotation of the pressure plate 427 can press down and fix the upper surface of the circuit board. At this time, the circuit board is located directly below the oil pollution monitoring device 31 , the oil pollution monitoring device 31 is used to monitor the oil pollution on the upper surface of the circuit board, and then the second rotating rod 45 can be driven to rotate. The second rotating rod 45 drives the pulley 46 on its surface to rotate. The pulley 46 is driven by a belt, so that the pulley 46 fixed on the surface of the first rotating rod 43 rotates synchronously, which can drive the first rotating rod 43 to rotate synchronously. At this time, the first rotating rod 43 can drive the placement rack to rotate, and the placement rack drives the circuit board to rotate under the oil pollution monitoring device 31, that is, various angles and parts of the circuit board surface can be observed, which is helpful to find epoxy resin drilling pollution at different angles, obtain more comprehensive observation results, and judge whether the circuit board contains oil pollution.

[0038] like Figure 1 As shown, a first motor 11 is fixedly connected to the side wall of the body 1 , and an output end of the first motor 11 is fixedly connected to the rotating end of the conveyor belt 2 .

[0039] Specifically, the first motor 11 is turned on to work, and the first motor 11 rotates and drives the rotating end of the conveyor belt 2 to rotate synchronously, thereby driving the conveyor belt 2 to rotate and transport the circuit board.

[0040] like Figure 4 As shown, a display screen 32 is provided on the side surface of the fixed shell 3 , and a manipulator 33 is provided on a side of the fixed shell 3 away from the first motor 11 .

[0041] Specifically, the oil pollution monitoring device 31 and the manipulator 33 can be turned on or off through the display screen 32. When the oil pollution monitoring device 31 detects that the surface of the circuit board contains oil pollution, the manipulator 33 uses existing technology, and the oil pollution monitoring device 31 transmits a signal to the manipulator 33, and the manipulator 33 works to remove the circuit board with oil pollution. When the oil pollution monitoring device 31 detects that the surface of the circuit board does not contain oil pollution, the oil pollution monitoring device 31 transmits a signal to the manipulator 33, and the manipulator 33 can grab the circuit board and place it in the storage area.

[0042] like Figures 6 and 7As shown, a support frame 42 is provided on one side of the fixed frame 41, and a fixed rod 423 is slidably connected inside the support frame 42, and one end of the fixed rod 423 is fixedly connected to the second conical block 424, and the first rotating rod 43 is slidably connected inside the moving rod 425, and one end of the moving rod 425 is rotatably connected to one end of the pressure plate 427, and the placement frame is rotatably connected to a connecting rod 428 inside, and the other end of the connecting rod 428 is rotatably connected to one side of the pressure plate 427, one end of the fixed rod 423 is fixedly connected to a connecting plate 429, and one end of the connecting plate 429 is fixedly connected to a limiting rod 430, and the interior of the main body 1 is fixedly connected to the limiting plate 12, and the surface of the limiting plate 12 is provided with a protrusion 121, and one end of the limiting rod 430 is in contact with the surface of the limiting plate 12.

[0043] Specifically, the circuit board is placed inside the placement plate 44, and the fixed plate 4 moves with the conveyor belt 2. When the limit rod 430 moves to the raised portion 121 of the limit plate 12, the limit rod 430 squeezes the connecting plate 429 to move, and the connecting plate 429 drives the fixing rod 423 inside the support frame 42. The fixing rod 423 drives the second conical block 424 to slide inside the first rotating rod 43. The second conical block 424 slides and squeezes the moving rod 425 to slide upward. The moving rod 425 pushes one end of the pressing plate 427, and the pressing plate 427 is rotated through the connecting rod 428, so that one end of the pressing plate 427 is pressed and fits tightly against the upper surface of the circuit board, and the circuit board can be automatically fixed.

[0044] like Figure 7 and Figure 8 As shown, the side wall of the fixed plate 4 is fixedly connected with a sliding rod 431, the surface of the sliding rod 431 is slidably connected to the inside of the connecting plate 429, a fifth spring 433 is fixedly connected between one side of the connecting plate 429 and the fixed plate 4, a fourth spring 432 is fixedly connected between one side of the second conical block 424 and the support frame 42, and a third spring 426 is fixedly connected between the circumferential surface of the movable rod 425 and the inner wall of the rotating rod.

[0045] Specifically, when the connecting plate 429 is pushed by the limiting rod 430, the connecting plate 429 slides synchronously on the surface of the sliding rod 431, and the connecting plate 429 can squeeze the fifth spring 433. At the same time, the second conical block 424 can stretch the fourth spring 432 when the first rotating rod 43 slides. The second conical block 424 squeezes the moving rod 425 to rise, and the moving rod 425 squeezes the third spring 426. When the limiting rod 430 disengages from the protrusion 121 of the limiting plate 12, the fifth spring 433 drives the connecting plate 429 to reset and slide on the surface of the sliding rod 431. The second conical block 424 resets and slides through the fourth spring 432, so that the limiting rod 430 keeps one side of the limiting plate 12 in contact. After the second conical block 424 is reset, the third spring 426 drives the moving rod 425 to slide downward and reset.

[0046] Example 2

[0047] like Figures 8 and 9 As shown, compared with Example 1, another embodiment of the present invention is: the interior of the second rotating rod 45 is slidably connected to a connecting rod 414, one end of the connecting rod 414 is fixedly connected to a connecting block 413, the circumferential surface of the connecting block 413 is fixedly connected to a limiting block, the inner wall of the fixed shell 3 is slidably connected to a movable plate 48, one side of the movable plate 48 is fixedly connected to a second motor 49, the output end of the second motor 49 is fixedly connected to a rotating sleeve 411 through an insulating rod, the interior of the rotating sleeve 411 is fixedly connected to a connecting groove 412, the shape of the connecting groove 412 corresponds to the shape of the connecting block 413, the upper surface of the movable plate 48 is fixedly connected to an electromagnet 410, and the magnetism of the electromagnet 410 and the magnetism of the connecting block 413 are attracted to each other after power is applied.

[0048] Specifically, in the prior art, circuit boards are generally fixed, and the oil stain monitoring device 31 has a limited monitoring angle. Since the distribution and shape of stains may be uneven, the oil stain monitoring device 31 may not be able to accurately detect stains on the circuit board surface.

[0049] When the present invention is in use, when the circuit board moves to the position directly below the oil pollution monitoring device 31, the movable plate 48 can be driven to drive the second motor 49 and the electromagnet 410 to slide synchronously, and the second motor 49 drives the rotating sleeve 411 to slide synchronously. One side of the rotating sleeve 411 is in contact with one end of the second rotating rod 45, and the electromagnet 410 is turned on to generate magnetic force. The magnetic force sucks the connecting block 413 into the interior of the connecting groove 412, and the second motor 49 drives the rotating sleeve 411 to rotate. The rotating sleeve 411 can drive the second rotating rod 45 to rotate synchronously. The second rotating rod 45 rotates through the pulley 46, and the pulley 46 is driven by the belt, so that the pulley 46 on the surface of the first rotating rod 43 rotates synchronously, and the first rotating rod 43 can be driven to drive the placement plate 44 to rotate synchronously.

[0050] The circuit board can be driven to rotate, thereby facilitating the oil pollution monitoring device 31 to observe epoxy resin drilling pollution at various angles and locations on the surface of the circuit board, thereby improving the monitoring efficiency of the circuit board.

[0051] like Figure 6 and Figure 9 As shown, one end of the connecting rod 414 is fixedly connected to the first conical block 416, and the second rotating rod 45 is symmetrically slidably provided with an insertion rod 418 inside. One end of the insertion rod 418 is in contact with the circumferential surface of the first conical block 416. One side of the fixing frame 41 is fixedly connected to the arc frame 417, and the arc frame 417 is provided with a socket 420 inside. The size of the socket 420 matches the size of the insertion rod 418.

[0052] Specifically, when the connecting block 413 is adsorbed by the electromagnet 410, the connecting block 413 drives the connecting rod 414 to slide synchronously, and the connecting rod 414 drives the first conical block 416 to slide toward the outside of the second rotating rod 45. At this time, the insertion rod 418 slides inside the second rotating rod 45, and one end of the insertion rod 418 disengages from the inside of the socket 420, which can release the limit between the second rotating rod 45 and the arc frame 417, and the second rotating rod 45 can be driven to rotate. When the connecting block 413 is in the initial position, the insertion rod 418 is located inside the socket 420, and the second rotating rod 45 can perform a limit operation with the arc frame 417.

[0054] Specifically, when the connecting block 413 is out of the adsorption distance of the electromagnet 410, the connecting block 413 is driven by the first spring 415 to enter the interior of the second rotating rod 45, and the connecting rod 414 drives the second conical block 416 to reset, and the second conical block 416 squeezes the insertion rod 418 to slide toward the outside of the second rotating rod 45. When the insertion rod 418 slides, it squeezes the second spring 419. When the second conical block 416 slides toward the outside, the second spring 419 is reset and drives the insertion rod 418 to slide toward the inside of the second rotating rod 45.

[0055] like Figure 6 As shown, the circumferential surface of the second rotating rod 45 is fixedly connected to the first counterweight 421 , and the circumferential surface of the rotating sleeve 411 is fixedly connected to the second counterweight 422 .

[0056] Specifically, when the connecting block 413 is out of the adsorption distance of the electromagnet 410, the first counterweight block 421 can drive the second rotating rod 45 to rotate through gravity, so as to drive the insertion rod 418 to rotate to the position of the socket 420 to fix the second rotating rod 45. When the second motor 49 is turned off, the rotating sleeve 411 can be rotated by the second counterweight block 422 through gravity, thereby facilitating the positioning connection between the connecting block 413 and the connecting slot 412.

[0057] like Figure 10 As shown, one end of the fixed shell 3 is fixedly connected to a cylinder 47, and the movable end of the cylinder 47 is fixedly connected to one side of the movable plate 48.

[0058] Specifically, the cylinder 47 is turned on to work, and the cylinder 47 can drive the movable plate 48 to move. The movable plate 48 can separate the electromagnet 410 from the adsorption of the connecting block 413, so that the connecting block 413 is reset.

When the circuit board moves to the bottom of the oil pollution monitoring equipment 31, the cylinder 47 is turned on to work. The cylinder 47 can drive the moving plate 48 to move, and the moving plate 48 drives the second motor 49 and the electromagnet 410 to slide synchronously.

At this time, the insertion rod 418 slides inside the second rotating rod 45, and one end of the insertion rod 418 disengages from the inside of the socket 420, and the limit between the second rotating rod 45 and the arc frame 417 can be released. The second motor 49 drives the rotating sleeve 411 to rotate, and the rotating sleeve 411 can drive the second rotating rod 45 to rotate synchronously. The second rotating rod 45 rotates through the pulley 46, and the pulley 46 is driven by the belt, so that the pulley 46 on the surface of the first rotating rod 43 rotates synchronously, which can drive the first rotating rod 43 to drive the release When the second conical block 424 is reset and slides, the second conical block 424 is reset and slides, so that the limit rod 430 keeps one side of the limit plate 12 in contact with it.
