Description

Technical Field

[0001] The invention relates to the field of pressure-stabilizing spray discs, and in particular to a pressure-stabilizing spray disc device for a glass substrate. Background Art

[0002] In the current vertical wet PCB processing technology system, an integral spray plate structure is commonly used, which has significant limitations. Specifically, the distance between each nozzle on the spray plate and the board surface is consistent, which causes a series of problems. For example, the fluidity and characteristics of the liquid medicine lead to lower water pressure in the upper area, making it difficult to achieve precise control of the supply of liquid medicine at different positions. The liquid medicine tends to flow downstream under the action of gravity, so that the amount of liquid medicine retained in the upper part is significantly less than that in other areas, seriously affecting the uniformity and consistency of the liquid medicine distribution on the board surface. At the same time, since the water pressure generated by the pump is in a non-continuous and stable state, there are intermittent fluctuations, which may cause the pressure of the liquid medicine sprayed from the nozzle to become unstable, thereby adversely affecting the processing effect of the PCB board surface and glass substrate, and reducing product quality and performance. In addition, the traditional structure has poor adaptability to PCBs and glass substrates of different specifications and types, which limits the flexibility of production.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0040] As described in the background art, in the current vertical wet PCB processing technology system, an integral spray plate structure is generally used, which has significant limitations.

[0041] In order to solve this technical problem, the present invention provides a glass substrate pressure-stabilizing spray plate device, which is applied to a pressure-stabilizing spray plate that can be adjusted in different areas.

[0042] Specifically, please refer to Figure 1-Figure 13 The glass substrate pressure-stabilizing spray disc device specifically includes a symmetrically arranged frame 1 and a filter assembly 17 arranged at the bottom of the frame 1. A connecting steel plate 3 is symmetrically installed on the top of the frame 1, and the top of the connecting steel plate 3 is fixedly connected to the external eccentric wheel. Four groups of spray discs 2 are evenly arranged on the inner side of the frame 1 from top to bottom. Three groups of water tanks 11 are arranged on the side walls of the four groups of spray discs 2 at intervals up and down, and the two ends and the middle of the three groups of water tanks 11 are connected. Liquid outlet holes 12 are evenly arranged inside the water tanks 11. Six groups of liquid outlet holes 12 are evenly arranged inside the water tanks 11 opened inside the three groups of spray discs 2 located at the bottom. The water trough 11 opened inside the upper group of spray discs 2 is evenly provided with ten groups of liquid outlet holes 12, and an additional group of liquid outlet holes 12 is added between the two upper groups of water troughs 11, and the liquid outlet holes 12 penetrate the spray disc 2. The size of the water trough 11 located at the upper part is slightly larger than the water trough 11 set on the inner wall of the three lower groups of spray discs 2. A sealing cover 4 is provided on the outer side of the spray disc 2, and the sealing cover 4 matches the water trough 11. A liquid inlet pipe 13 is connected to the middle pipe on the outer side of the sealing cover 4, and the liquid inlet pipe 13 penetrates the water trough 11 through the sealing cover 4. A nozzle 10 is correspondingly provided on the other side of the spray disc 2 through the liquid outlet hole 12.

[0043] In the glass substrate pressure stabilizing spray plate device provided by the present invention, two groups of eccentric wheels rotate and cooperate with the connecting steel plates 3 fixedly connected thereto to drive the two groups of frames 1 to rotate, thereby adjusting the distance between the two groups of frames 1.

[0044] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0045] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0046] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0047] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 A glass substrate pressure stabilizing spray disc device, wherein a limit slider 8 is symmetrically installed on the outer side of the spray disc 2, and the limit slider 8 is fixedly connected to an external electric push rod on one side perpendicular to the spray disc 2, and the electric push rod moves synchronously with the frame 1, and a linear slide rail 7 is slidably arranged on the other side of the limit slider 8, and the other end of the linear slide rail 7 is fixedly connected to the inner side of the frame 1, a limit steel plate 9 is arranged below the linear slide rail 7, and the limit steel plate 9 is sleeved with the spray disc 2, and pulley connecting plates 5 are symmetrically arranged on both sides of the frame 1, and a pulley 6 is rotatably arranged inside the pulley connecting plate 5.

[0048] The electric push rod pushes the limit slider 8 to slide on the linear slide rail 7, and pushes the spray disc 2 to move under the limit of the limit steel plate 9, thereby adjusting the position of the spray disc 2 in different areas.

[0049] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 A glass substrate pressure stabilizing spray disc device, wherein the outer sides of the two sets of frames 1 are provided with buffer chambers 14, and the liquid outlet end of the buffer chamber 14 is provided with a pressure stabilizing valve 15, and the other end of the pressure stabilizing valve 15 extends out of four sets, and the stabilizing valve 15 is respectively connected to the four sets of liquid inlet pipes 13, and the outer wall of the liquid inlet pipe 13 is provided with a detection and adjustment component 16.

[0050] The detection and adjustment component 16 has its own flow rate and pressure sensors for detecting the flow of the liquid medicine. Before being transported, the liquid medicine is first absorbed and buffered by the buffer chamber 14 and the pressure-stabilizing valve 15, and then detected in conjunction with the detection and adjustment component 16, so as to make the distribution of the liquid medicine more uniform.

[0051] Example 2 further optimizes the glass substrate pressure stabilizing spray plate device provided in Example 1. Specifically, Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, the two groups of filter components 17 include right-angle plates 1701 symmetrically arranged at the bottom of the two groups of frames 1, and the inner walls of the two groups of right-angle plates 1701 are respectively installed with the first orifice plate 1703 and the second orifice plate 1704, the ends of the first orifice plate 1703 and the second orifice plate 1704 are both curved, the first orifice plate 1703 is horizontally arranged, the second orifice plate 1704 is inclined, and the first orifice plate 1703 and the second orifice plate 1704 are in contact with each other through the ends, and the bottom of the second orifice plate 1704 is installed with a pull rod 1706 at intervals, and the bottom of the pull rod 1706 is fixedly installed with a rubber sheet 1702, and the two ends of the rubber sheet 1702 are respectively connected to the first orifice plate 1703 and the second orifice plate 1704.

[0052] The first orifice plate 1703 and the second orifice plate 1704 are used to perform preliminary filtering on the liquid medicine dripping from between the frames 1 .

[0053] Furthermore, Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, a top groove 1719 extending inward is provided at the top of the right angle plate 1701, and pull ropes 1707 are evenly arranged on the inner wall of the right angle plate 1701. One end of the pull rope 1707 is connected to the inner wall of the right angle plate 1701, and the other end of the pull rope 1707 passes through the top groove 1719 and extends to the outside of the right angle plate 1701, and is fixedly connected to the bottom of the frame 1, and a filter cloth 1708 is fixedly installed on the outside of the pull rope 1707, and both ends of the filter cloth 1708 are fixedly connected to the inner wall of the right angle plate 1701, and the filter cloth 1708 is located below the first orifice plate 1703 and the second orifice plate 1704.

[0054] The right-angle plate 1701 is fixed to the bottom of the frame 1 by evenly arranged pull ropes, and the dripping liquid is filtered twice by the filter cloth 1708.

[0055] Furthermore, Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, right-angle shafts 1705 are installed at both ends of the first orifice plate 1703 and the second orifice plate 1704, and side grooves are opened on the left and right sides of the two groups of right-angle plates 1701. The two groups of right-angle plates 1701 are respectively connected with the right-angle shafts 1705 fixedly installed on both sides of the first orifice plate 1703 and the second orifice plate 1704 that are not connected thereto through their side grooves, and a connecting rope 1709 is fixedly installed on the outer side of the right-angle shaft 1705, and the connecting rope 1709 passes through the filter cloth 1708 and extends to its bottom.

[0056] When the two sets of frames 1 move in different directions, the first orifice plate 1703 and the second orifice plate 1704 will be driven to shift horizontally, thereby causing the right-angle shaft 1705 to slide along the side groove of the right-angle plate 1701 and pull the connecting rope 1709 to move synchronously.

[0057] Furthermore, Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, the inner walls of the two groups of right-angle plates 1701 are symmetrically provided with billiard balls 1712 , which are located at the bottom of the filter cloth 1708 . The billiard balls 1712 are connected to the inner walls of the right-angle plates 1701 through thin ropes, and the thin ropes are connected to the connecting ropes 1709 .

[0058] The billiard ball 1712 connected by a thin rope will shake when the right-angle plate 1701 moves, and can also shake quickly when the connecting rope 1709 pulls something.

[0059] Furthermore, Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, a pad 1713 is disposed on the inner side of the billiard ball 1712 , and spring pieces 1714 are disposed on the outer side of the pad 1713 at intervals. The spring pieces 1714 are arc-shaped, and the spring pieces 1714 are in contact with the inner wall of the right-angle plate 1701 .

[0060] When the billiard ball 1712 is slowly shaken, it will continuously hit the pad 1713 and the spring 1714, causing the spring 1714 to vibrate on the inner wall of the right-angle plate 1701. The vibration can prevent the filter hole from being blocked. When the billiard ball 1712 is pulled by the connecting rope 1709, it will quickly hit the pad 1713 and force the spring 1714 to bend completely.

[0061] Furthermore, Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, a triangular plate 1715 is fixedly installed on the other side of the pad 1713 , the triangular plate 1715 penetrates the right-angle plate 1701 and extends to the outside thereof, and the right-angle plate 1701 and the triangular plate 1715 are slidably sleeved.

[0062] When the billiard ball 1712 hits the backing plate 1713 slowly, the triangular plate 1715 moves slightly. When the billiard ball 1712 hits the backing plate 1713 quickly, the triangular plate 1715 accelerates and slides greatly.

[0063] Furthermore, Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, the top of the right angle plate 1701 is sleeved with a card plate 1710 through a top groove 1719, the bottom of the card plate 1710 is in contact with the pull rope 1707, the bottom of the card plate 1710 is symmetrically installed with a connecting rod 1711, and the bottom of the connecting rod 1711 is an open spherical shape, the connecting rod 1711 penetrates the right angle plate 1701 and extends to its side wall, the bottom of the connecting rod 1711 is clamped with a sliding rod 1716, one end of the sliding rod 1716 is thick and the other end is thin, the thicker end of the sliding rod 1716 is fixedly installed with a return spring 1718, the middle part of the thinner end of the sliding rod 1716 is hollow, and the sliding rod 1716 is sleeved with the triangle plate 1715.

[0064] The right-angle plate 1701 is correspondingly connected with the connecting rod 1711, the sliding rod 1716 and the return spring. The triangular plate 1715 slides and pushes the sliding rod 1716 to move. When the thicker end of the sliding rod 1716 is separated from the bottom of the connecting rod 1711, the right-angle plate 1701 pulls the pull rope 1707 downward under the action of gravity, and squeezes the connecting rod 1711 and the clamping plate 1710 to make them rise inside the right-angle plate 1701.

[0065] The use process of the glass substrate pressure stabilizing spray plate device provided by the present invention is as follows:

[0066] Pressure-stabilized feeding: The liquid medicine is transported from the external pump body to the inside of the buffer chamber 14 through the provided liquid inlet pipe 13, the buffer chamber 14, the pressure-stabilizing valve 15 and the detection and adjustment component 16, and the pressure fluctuation of the liquid medicine is absorbed and buffered by the buffer chamber 14, so as to provide a stable liquid medicine input to the spray disc 2 through the pressure-stabilizing valve 15 and the liquid inlet pipe 13. During the liquid medicine transportation process, the liquid medicine transportation data is always detected by the pressure and flow rate sensor inside the detection and adjustment component 16, so as to realize stable pressure control, thereby improving the stability of the spraying effect;

[0067] Frame 1 spacing adjustment: Frame 1 is connected to the external eccentric wheel through the connecting steel plate 3 symmetrically arranged on the top thereof, so the rotation of the external eccentric wheel can drive the frame 1 to rotate synchronously. When the two sets of eccentric wheels rotate, the two sets of frames 1 will be kept rotating in the same direction and at the same angle, so that the inner walls of the two sets of frames 1 are always at equal spacing from the two sides of the glass substrate. When the frame 1 moves, the four sets of spray discs 2 adjacently distributed inside the frame 1 will also be driven to move;

[0068] Position adjustment of the spray disc 2: Since the limit sliders 8 are symmetrically arranged on both sides of each group of spray discs 2, and the outer side of each limit slider 8 is fixedly connected to the external electric push rod, during use, the limit sliders 8 on both sides of different spray discs 2 can be automatically pushed by the electric push rod or the limit sliders 8 can be manually adjusted according to the thickness of the plate and the machine parameters. The spray discs 2 in different areas move back and forth within the range of the limit steel plate 9 to adapt to different plate thicknesses, while ensuring that the PCB board or glass substrate is not at risk of being crushed or scratched. The spray discs 2 in different areas move back and forth and coordinate with the detection and adjustment component 16 to adjust the liquid spray pressure and liquid distribution of the plate to meet the different spraying requirements of different areas and achieve precision spraying;

[0069] Collection and filtration of liquid medicine: Since the bottom of the two groups of frames 1 are fixedly installed with right-angle plates 1701, and the inner sides of the two groups of right-angle plates 1701 are connected to each other through rubber sheets 1702, when the frame 1 is adjusted, the right-angle plates 1701 will move synchronously. At this time, as the two groups of frames 1 continue to approach each other, the two groups of right-angle plates 1701 will bring the first orifice plates 1703 and the second orifice plates 1704 installed on their inner walls closer to each other. Since the sides of the first orifice plates 1703 and the second orifice plates 1704 that are close to each other are both arc-shaped and in contact with each other, the first orifice plates 1703 and the second orifice plates 1704 can also remove impurities from their inner walls as their positions are continuously adjusted. At this time, the liquid medicine continuously flows down from between the two groups of frames 1, and is filtered once through the first orifice plates 1703 and the second orifice plates 1704, and then filtered twice through the filter cloth 1708, thereby fully filtering out the impurities inside the liquid medicine;

[0070] At the same time, as the two groups of right-angle plates 1701 move, the billiard balls 1712 symmetrically arranged on the inner wall thereof can also be driven to shake. Since the billiard balls 1712 are connected to the inner wall of the right-angle plate 1701 only by a thin rope, when the right-angle plate 1701 moves, the billiard balls 1712 will be driven to shake irregularly and hit the pad 1713 arranged on one side thereof, thereby hitting the right-angle plate 1701 through the spring pieces 1714 spaced apart on the outer side of the pad 1713, causing it to shake and then drive the parts fixedly connected thereto to shake, thereby avoiding blockage during the filtering process;

[0071] Recovery and processing of the liquid medicine; when a proper amount of liquid medicine is accumulated inside the right-angle plate 1701, and there is no PCB board or glass substrate that needs to be sprayed, the eccentric wheel is accelerated and rotated in the same direction, so that the two sets of frames 1 move in opposite directions. At this time, the rubber sheet 1702 is pulled, and because the two sets of frames 1 move in opposite directions, the first hole plate 1703 and the second hole plate 1704 are driven to shift in the horizontal position, and the right-angle shafts 1705 installed on both sides thereof slide toward the sides of the side walls of the right-angle plate 1701, and then the connecting rope 1709 connected to the right-angle shaft 1705 is quickly pulled to move, and the billiard ball 1712 is quickly pulled through it, so that it quickly hits the pad 1713, and when the pad 1713 is hit, the spring piece 1714 is quickly squeezed And move inward. During the movement, the triangular plate 1715 fixedly installed on the other side cooperates with the connecting groove 1717 to push the slide bar 1716 to squeeze the reset spring 1718 and slide on the inner wall of the right-angle plate 1701, so that the thicker part of the slide bar 1716 is separated from the bottom of the connecting rod 1711. At this time, the right-angle plate 1701 moves downward under the action of gravity and is straightened by the pull rope 1707, thereby pushing the card plate 1710 out of the top groove 1719. At this time, both sets of right-angle plates 1701 move downward and are only connected to each other by the pull rope 1707, so it is convenient to tilt them to clean the medicine inside. After cleaning, you only need to push up the two sets of right-angle plates 1701 to re-engage the slide bar 1716 with the bottom of the connecting rod 1711.
