Description

Technical Field

[0001] This utility model relates to the field of precision instrument PCBA, specifically a water washing spray device for precision instrument PCBA. Background Technology

[0002] PCBA (Printed Circuit Board Assembly) is an abbreviation for the printed circuit board assembly process, which refers to the process of assembling components on a blank PCB board using surface mount technology (SMT) or dual in-line package technology (DIP).

[0003] In the PCBA (Printed Circuit Board Assembly) process, the main purpose of washing is to remove residual flux and other contaminants after soldering. If these residues are not removed, they can lead to corrosion, short circuits, or other performance problems on the circuit board. As electronic components become smaller and solder gaps become smaller, residual contaminants can cause electrical malfunctions, making cleaning particularly important. When cleaning printed circuit boards (PCBs), they are usually placed directly on a conveyor belt or a rack, and then cleaned by a spray system. However, because the PCBs are placed directly, the back cannot be cleaned after the front is cleaned. If there are contaminants on the back of the PCB, it may cause damage and potentially lead to electrical malfunctions during subsequent use.

[0004] Therefore, a water washing spray device for precision instrument PCBA is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the problem that because printed circuit boards are placed directly, the back of the printed circuit board cannot be cleaned after the front is cleaned, which may cause damage to the printed circuit board if there are contaminants on the back, potentially leading to electrical failures during subsequent use, this utility model proposes a water washing spray device for precision instrument PCBA.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The precision instrument PCBA water washing spray device of this utility model includes a device body, a control device fixedly connected to the outside of the device body, a rotating component provided inside the device body, the rotating component including two slide bars slidably connected inside the device body, a placement frame fixedly connected between the two slide bars, a positioning soft block fixedly connected inside the placement frame, a first rotating rod rotatably connected inside the placement frame, an installation frame fixedly connected to the end of the first rotating rod, two installation frames are provided, a connecting rod fixedly connected between the two installation frames, a second rotating rod fixedly connected to the end of the installation frame, and a gear fixedly connected to the end of the second rotating rod.

[0007] Preferably, the device body is provided with a power component, the power component includes transmission teeth meshing with the outside of the gear, a transmission block is fixedly connected to the bottom of the transmission teeth, a limit slider is fixedly connected to the bottom of the transmission block, and the outside of the limit slider is slidably connected to the inside of the device body.

[0008] Preferably, the power assembly further includes a first screw threadedly connected inside the transmission block, one end of the first screw being rotatably connected to the inside of the device body, and the other end being fixedly connected to a motor, which is fixedly connected inside the device body.

[0009] Preferably, the mounting frame is provided with a placement component, the placement component including a limiting base plate fixedly connected to the inside of the mounting frame, and a drain outlet is provided inside the mounting frame, the drain outlet being located above the limiting base plate.

[0010] Preferably, the placement assembly further includes a push block slidably connected to the top of the limiting base plate, a clamping plate fixedly connected to the top of the push block, the outer side of the clamping plate slidably connected to the inside of the mounting frame, a second screw threadedly connected to the inside of the clamping plate, one end of the second screw being rotatably connected to the inside of the mounting frame, and the other end passing through the mounting frame and being rotatably connected, and a knob fixedly connected to the end of the second screw.

[0011] Preferably, the device body is provided with a sealing component on the outside. The sealing component includes a sealing frame that is slidably connected to the inside of the device body. A transparent glass is fixedly connected inside the sealing frame, and a handle is fixedly connected to the outside of the sealing frame.

[0012] Preferably, the enclosure component further includes a blocking strip slidably connected to the outside of the enclosure frame, a connecting block fixedly connected to the outside of the blocking strip, a limiting plate fixedly connected to the end of the connecting block, and a sliding groove slidably connected to the outside of the connecting block and the limiting plate, the sliding groove being formed inside the device body.

[0013] The advantages of this utility model are: 1. This utility model uses the rotation of gears to drive the second rotating rod to rotate, which in turn drives the mounting frame to rotate, thereby driving the connecting rod to rotate. This causes the two mounting frames to rotate synchronously, which in turn drives the printed circuit board to rotate, so that the back of the printed circuit board faces upward. This makes it easier for the spray device to rinse the back of the printed circuit board, thereby cleaning away contaminants and reducing the possibility of damage to the printed circuit board, thus reducing the possibility of electrical failures during subsequent use.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 Please see Figure 1-4 As shown, a precision instrument PCBA water washing spray device includes a device body 1, a control device 2 fixedly connected to the outside of the device body 1, and a rotating assembly inside the device body 1. The rotating assembly includes two slide bars 3 slidably connected inside the device body 1, a placement frame 4 fixedly connected between the two slide bars 3, a positioning soft block 5 fixedly connected inside the placement frame 4, a first rotating rod 6 rotatably connected inside the placement frame 4, a mounting frame 7 fixedly connected to the end of the first rotating rod 6, two mounting frames 7 are provided, a connecting rod 8 fixedly connected between the two mounting frames 7, a second rotating rod 9 fixedly connected to the end of the mounting frame 7, and a gear 10 fixedly connected to the end of the second rotating rod 9.

[0020] During operation, the rotation of gear 10 drives the second rotating rod 9 to rotate, which in turn drives the mounting frame 7 to rotate, which in turn drives the connecting rod 8 to rotate. This causes the two mounting frames 7 to rotate synchronously, which in turn drives the printed circuit board to rotate, so that the back of the printed circuit board faces upward. This makes it easier for the spray device to rinse the back of the printed circuit board, thereby cleaning away contaminants and reducing the possibility of damage to the printed circuit board, thus reducing the possibility of electrical failures during subsequent use. The positioning soft block 5 can restrict the position of the mounting frame 7. After the printed circuit board is placed, the position of the mounting frame 7 can be restricted, which in turn restricts the position of the gear 10. This facilitates the subsequent meshing of the gear 10 with the transmission gear 11, and makes it easier for the transmission gear 11 to drive the gear 10 to rotate.

[0021] The device body 1 is equipped with a power component, which includes a transmission tooth 11 meshing with the outside of the gear 10. A transmission block 12 is fixedly connected to the bottom of the transmission tooth 11. A limit slider 13 is fixedly connected to the bottom of the transmission block 12. The outside of the limit slider 13 is slidably connected to the inside of the device body 1.

[0022] The power assembly also includes a first screw 14 threadedly connected inside the transmission block 12. One end of the first screw 14 is rotatably connected to the inside of the device body 1, and the other end is fixedly connected to a motor 15, which is fixedly connected inside the device body 1.

[0023] During operation, the motor 15 drives the first screw 14 to rotate, which in turn drives the transmission block 12 to move, thereby driving the limit slider 13 to move, which in turn drives the transmission gear 11 to move, thereby driving the gear 10 to rotate, thus transmitting power.

[0024] The mounting frame 7 is equipped with a placement component, which includes a limiting base plate 16 fixedly connected inside the mounting frame 7. The mounting frame 7 has a drain outlet 17 located above the limiting base plate 16.

[0025] The placement assembly also includes a push block 20 that is slidably connected to the top of the limiting base plate 16. A clamping plate 19 is fixedly connected to the top of the push block 20. The outer side of the clamping plate 19 is slidably connected to the inside of the mounting frame 7. A second screw 18 is threadedly connected to the inside of the clamping plate 19. One end of the second screw 18 is rotatably connected to the inside of the mounting frame 7, and the other end passes through the mounting frame 7 and is rotatably connected. A knob 21 is fixedly connected to the end of the second screw 18.

[0026] During operation, the printed circuit board is supported by the limiting base plate 16. Then, the knob 21 is turned, which drives the second screw 18 to rotate, thereby moving the clamping plate 19, which in turn moves the push block 20, thus clamping the printed circuit board and fixing its position. This prevents the printed circuit board from falling off when it rotates, thus cleaning the back of the printed circuit board and ensuring its safety.

[0027] Example 2 Please see Figure 5 As shown in the first embodiment, as another implementation of the present invention, a sealing component is provided on the outside of the device body 1. The sealing component includes a sealing frame 22 that is slidably connected to the inside of the device body 1. A transparent glass 23 is fixedly connected inside the sealing frame 22, and a handle 24 is fixedly connected to the outside of the sealing frame 22.

[0028] The enclosure component also includes a blocking strip 25 that is slidably connected to the outside of the enclosure frame 22. A connecting block 26 is fixedly connected to the outside of the blocking strip 25. A limiting plate 27 is fixedly connected to the end of the connecting block 26. A sliding groove 28 is slidably connected to the outside of the connecting block 26 and the limiting plate 27. The sliding groove 28 is opened inside the device body 1.

[0029] During operation, by pushing the closing frame 22, the opening of the device body 1 is sealed in conjunction with the transparent glass 23. Then, by pushing the blocking strip 25, the connecting block 26 and the limiting plate 27 slide inside the slide groove 28, thereby fixing the position of the closing frame 22. This facilitates the blocking of water inside the device body 1, thereby reducing the possibility of water being transmitted to the outside and causing pollution. It also facilitates the subsequent recycling of water by the device body 1, thereby reducing the waste of resources.

[0030] The working principle is as follows: the motor 15 drives the first screw 14 to rotate, which in turn drives the transmission block 12 to move, thereby driving the limit slider 13 to move, which in turn drives the transmission gear 11 to move, thereby driving the gear 10 to rotate, which in turn drives the second rotating rod 9 to rotate, which in turn drives the mounting frame 7 to rotate, which in turn drives the connecting rod 8 to rotate, so that the two mounting frames 7 rotate synchronously, thereby driving the printed circuit board to rotate, so that the back of the printed circuit board faces upward, making it easier for the spray device to rinse the back of the printed circuit board, thereby cleaning away contaminants, reducing the possibility of damage to the printed circuit board, and thus reducing the possibility of electrical failures during subsequent use.
