Description

Technical Field

[0001] This utility model belongs to the field of surface cleaning, specifically a PCB circuit board surface cleaning device. Background Technology

[0002] In the electronics manufacturing industry, PCB cleaning equipment is a key component for ensuring product quality. Existing equipment primarily removes contaminants such as dust, solder slag, and flux residue from PCB surfaces through physical brushing, chemical spraying, and ultrasonic cleaning. However, as PCBs become increasingly high-density, multi-layered, and sophisticated, traditional cleaning equipment is revealing numerous problems: incomplete cleaning of complex blind vias, buried vias, and fine-pitch traces; component shadow areas easily creating cleaning blind spots; mechanical brushing can damage the board surface; chemical cleaning poses environmental pollution and high energy consumption issues; and the equipment lacks adaptability to different PCB types and real-time monitoring and intelligent management functions, failing to meet the modern electronics manufacturing demands for efficient, precise, and environmentally friendly cleaning. These technological bottlenecks urgently need to be overcome through new cleaning processes and intelligent design.

[0003] Existing PCB circuit board surface cleaning devices require a special device to remove the PCB circuit board after cleaning.

[0004] Because it needs to be removed manually, and the PCB board is very thin, it is difficult to remove. Utility Model Content

[0006] A detergent assembly having a first groove;

[0007] The ejected component is placed in the first groove, and the ejected component includes an ejector plate on which a PCB circuit board is placed;

[0008] The ejector component ejects the ejector plate.

[0009] Preferably, the washing liquid assembly has a washing liquid inclined surface, which is the surface through which the washing liquid flows, and the washing liquid assembly includes a first water-blocking wall that blocks the washing liquid.

[0010] Preferably, the washing liquid assembly is provided with a first chamber.

[0011] Preferably, a liquid outlet assembly is installed above the washing liquid assembly. The liquid outlet assembly includes a liquid outlet pipe and a liquid outlet valve. Water flows from the liquid outlet pipe into the liquid outlet valve, and the liquid outlet valve can adjust the size of the water flow.

[0012] Preferably, the ejected assembly includes a rotating shaft and a fixed circular tube. The rotating shaft is fixedly mounted on the ejection plate, and a cavity is provided inside the fixed circular tube. The rotating shaft is installed inside the cavity, and the fixed circular tube is fixedly mounted on the bottom of the first groove. The rotating shaft can rotate on the fixed circular tube.

[0013] Preferably, the ejection assembly includes a fixing plate and a fixing block. The fixing block is fixedly mounted on the fixing plate. A limiting groove is provided on the fixing block. A slider is installed on the limiting groove and can slide on the limiting groove. A first protruding structure is provided on the slider.

[0014] Preferably, the ejection assembly includes a rotating disk and a connecting rod. The disk is provided with a second protruding structure. The two ends of the connecting rod are respectively fitted onto the first protruding structure and the second protruding structure. The two ends of the connecting rod can rotate on the first protruding structure and the second protruding structure.

[0015] Preferably, the ejection assembly includes an ejection rod, one end of which is fixedly mounted on the slider and can move up and down with the slider. The other end of the ejection rod passes through the washing liquid assembly and slides in contact with the ejection plate. The hole through which the ejection rod passes through the washing liquid assembly is sealed by a sealing ring.

[0016] Preferably, the ejection assembly includes a rotating handle and a bearing. A limit rod is fixedly installed on the rotating handle, and the bearing is fixedly installed on a fixed plate. A rotating rod is installed in the middle of the bearing, one end of which is connected to a rotating disk, allowing the rotating disk to rotate. The other end is connected to the rotating handle, and the rotation of the rotating handle can drive the rotation of the rotating disk.

[0017] Preferably, the ejection assembly includes a limiting unit, which includes a limiting housing, a limiting block, and a spring. The limiting housing is fixedly mounted on a fixed plate, and a chamber is provided inside the limiting housing. The spring is disposed in the chamber, the limiting block is fixed to one end of the spring, and the other end of the spring is fixed to the bottom of the chamber. When the limiting rod is engaged in the middle of the limiting block, the rotating disk does not rotate, and the ejection plate is at its highest position.

[0018] This application utilizes a rotating handle to drive a rotating disc, which, through the limiting action of a limiting groove, allows the slider to move only up and down. By converting the force in the rotational direction into a force in the up and down direction, the ejector rod pushes out the ejector plate, thereby ejecting the PCB circuit board and facilitating its removal.

Detailed Implementation

[0026] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0027] To address the problem of not being able to manually remove and pick up PCB circuit boards, this embodiment provides a PCB circuit board surface cleaning device.

[0028] like Figure 1 The PCB circuit board surface cleaning device shown includes: a liquid dispensing component, a washing liquid component 200, an outflow component 300, a ejected component 400, and an ejection component 500. The liquid dispensing component dispenses washing liquid and controls the flow rate of the washing liquid. The washing liquid component 200 provides a place to rinse the PCB circuit board. The outflow component 300 is used to collect the washing liquid. The ejected component 400 lifts the PCB circuit board above the washing liquid slope 210. The ejection component 500 ejects the ejected component 400.

[0029] like Figure 1 or Figure 2 As shown, the liquid outlet assembly includes a liquid outlet pipe 110 and a liquid outlet valve 120. The liquid outlet pipe 110 is a metal round pipe, and the liquid outlet valve 120 controls the outflow speed of the washing liquid. Different outflow speeds can be selected for different models of PCB circuit boards.

[0030] like Figure 1 or Figure 2 As shown, the washing liquid assembly 200 includes a washing liquid inclined surface 210, a first groove 220, a first water-blocking wall 230, and a first chamber 240. The washing liquid inclined surface 210 and the first groove 220 form an upward-opening chamber in which the washing liquid flows. The first groove 220 is disposed on the surface of the washing liquid inclined surface 210 and is used to place a PCB circuit board. The first chamber 240 is located below the washing liquid assembly 200 and is shaped like a triangular prism.

[0031] As shown in Figure 3, the ejected assembly 400 includes an ejector plate 410, a rotating shaft 420, and a fixed cylindrical tube 430. The ejector plate 410 is a flat cuboid made of metal. The ejector plate 410 causes the PCB circuit board to rise upwards and exceed the washing liquid inclined surface 210. The length of the ejector plate 410 is slightly smaller than that of the PCB circuit board, and the PCB circuit board extends beyond the ejector plate 410, making it easier to clamp the PCB circuit board. The rotating shaft 420 consists of two metal shafts. The cylinder has two rotating shafts 420 fixed to one end of the ejector plate 410 near the bottom. The rotating shafts 420 are welded to the ejector plate 410. The fixed circular tube 430 is a hollow metal circular tube, which is welded to the washing liquid inclined surface 210. The two ends of the fixed circular tube 430 are respectively fitted with two rotating shafts 420. The rotating shafts 420 can rotate on the fixed circular tube 430. Therefore, the ejector plate 410 can rotate around the fixed circular tube 430.

[0032] like Figure 4 or Figure 5As shown, the ejector assembly 500 includes a fixed plate 510, an ejector rod 530, a rotating disc 540, a rotating handle 550, a first protruding structure 560, a second protruding structure 570, a connecting rod 580, a bearing 590, and a limiting unit 5100. The fixed plate 510 is a cuboid made of metal, and a limiting groove 522 is provided on the fixed plate 510. The slider 521 is installed inside the limiting groove 522, which is a trapezoidal cavity. The slider 521 is a cylinder with trapezoidal top and bottom surfaces. The slider 521 is connected to the limiting unit 5100. The slider 521 can move up and down on the limiting groove 522, and the ejector rod 530 is a rectangular cylinder. The end of the ejector rod 530 is fixedly connected to the slider 521, and the top of the ejector rod 530 slides in contact with the ejector plate 410. The ejector rod 530 is a metal L-shaped rod. A first protruding structure 560 is fixedly installed on the slider 521. The rotating disk 540 is a flat cylinder made of metal. A second protruding structure 570 is fixedly installed at the corner of the rotating disk. The bearing 590 is fixedly installed on... On the fixed plate 510, the rotating disk 540 is connected to the bearing 590 via a rotating rod, allowing the rotating disk 540 to rotate. A rotating handle 550 is connected to the other end of the bearing 590; rotating the handle 550 controls the rotation of the rotating disk 540. The rotating disk 540 and the rotating handle 550 rotate coaxially. The first protruding structure 560 and the second protruding structure 570 are connected via a connecting rod 580, which can rotate on both the first and second protruding structures. The rotating handle 550 drives the rotating disk. After rotation of 540, the second protruding structure 570 moves in a circular motion on the disk. The bottom end of the connecting rod 580 moves in a circular motion along with the second protruding structure 570. Due to the limiting effect of the limiting groove 522, the top end of the connecting rod 580 can only move up and down. The connecting rod 580 drives the slider 521 to move up and down. When the second protruding structure 570 rotates the bottom end of the disk 540, the slider 521 is at the lowest end. When the second protruding structure 570 rotates the top end of the disk 540, the slider 521 is at the highest end of the limiting groove 522.

[0033] like Figure 5 or Figure 6As shown, a limiting rod 551 is provided at one end of the connecting bearing 590 of the rotating handle 550. When the limiting rod 551 is at the bottom, the second protruding structure 570 on the rotating disk is at the top. When the limiting rod 551 is rotated to the bottom by rotating the rotating handle 550, the limiting rod 551 will be stuck in the limiting unit 5100, so that the rotating disk 540 will not rotate after the external force is applied. The limiting unit 5100 includes a limiting shell, a limiting block, and a spring. The limiting shell is fixedly installed on the fixing plate 510. A cavity is provided inside the limiting shell. The spring is fixedly installed inside the cavity. The limiting block is fixedly installed on the outer end of the spring. The outer end is two limiting blocks. The bottom end of the limiting block is a solid cuboid.
