Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1 to 3, the present application discloses a fluid dispensing device, which includes: the feeding pipe 1 is communicated with the feeding device 6; the discharge pipe 2 is communicated with the output mechanism 10; the ball valve 20 is provided with a through first channel, the first end 21 of the first channel can be communicated with the feeding pipe 1, and the second end 22 of the first channel can be communicated with the discharging pipe 2; the ball valve driving part 4 is connected with the ball valve 20 and can drive the ball valve 20 to rotate, so that the opening degree of the second end 22 and the discharge pipe 2 is controlled, and the inlet flow of the output mechanism 10 is reduced or increased; a pressure sensor 5 for detecting the pressure of the fluid in the output mechanism 10; the output mechanism 10 comprises at least two output channels 11, and an adjusting valve 30 is arranged on any one output channel 11; when the ball valve 20 is communicated with the feeding pipe 1 and the discharging pipe 2, the fluid supplied by the feeding device 6 enters the output channel 11; by adjusting the flow in the output channel 11 by means of the regulating valve 30, the pressure sensor 5 is able to detect the pressure change in the output mechanism 10, so that the ball valve driver 4 drives the ball valve 20 to rotate, by adjusting the inlet flow of the output mechanism 10, so that the pressure in the output mechanism 10 remains constant.

Wherein, the ball valve driving member 4 can adopt a motor.

Wherein, the ball valve 20 is a valve body with a ball-shaped main body and a first channel therein; the first channel has at least two ports (a first end 21 and a second end 22), either of which opens at the surface of the sphere. The first passage may extend linearly, may extend arcuately, and may extend curvilinearly, and the configuration of the first passage is not limited in the present application.

In one embodiment, referring to FIG. 1, a ball valve 20 is shown having a first passage extending therethrough in a vertical direction; the first end 21 of the first channel is at the top of the ball valve 20, the second end 22 is at the bottom of the ball valve 20, and the first end 21 and the second end 22 are arranged at two ends of a diameter of the sphere; the ball valve driver 4 is connected to the right portion of the ball valve 20. Thus, when the ball valve 20 is driven by the ball valve driving member 4 to rotate, the ball valve 20 rotates around the diameter extending in the left-right direction of the sphere, and simultaneously, the first end 21 and the second end 22 form a circle along the vertical diameter of the sphere to perform circular motion.

In this embodiment, the feed pipe 1 and the discharge pipe 2 are arranged outside the illustrated sphere vertical diameter forming circle. So, when ball valve 20 rotated certain angle, inlet pipe 1 can be relative with first end 21, realize the intercommunication, simultaneously, discharging pipe 2 can be relative with second end 22, realize the intercommunication, and the fluid passes through inlet pipe 1, first end 21, first passageway, second end 22, discharging pipe 2, gets into output mechanism 10. When the ball valve 20 continues to rotate, the relative angle between the tapping pipe 2 and the second end 22 changes, the cross-sectional area of the communication position between the tapping pipe and the second end is relatively increased or decreased, and when the communication area (i.e., "opening") between the tapping pipe and the second end is increased, fluid can more easily enter the tapping pipe 2; in contrast, when the opening degrees of the two are reduced, the fluid supplied from the first passage is blocked by the wall surface of one side of the discharge pipe 2, and the flow rate of the fluid entering the discharge pipe 2 from the second end 22 is reduced; since the tapping pipe 2 is directly connected to the discharge device 10, the fluid flow entering the tapping pipe 2 is also the "inlet flow" of the discharge device 10.

It should be added that the first end 21 and the second end 22 of the first channel can be arranged at any position on the surface of the ball valve 20, as long as the positions of the first end 21 and the second end 22 are changed synchronously during the rotation of the ball valve 20. Similarly, the feeding pipe 1 is correspondingly arranged on the moving path of the first end 21, and the discharging pipe 2 is correspondingly arranged on the moving path of the second end 22.

Furthermore, when the amount of fluid output from the discharge pipe 2 is small and the amount of fluid supplied from the supply device 6 is constant, it is necessary to branch the amount of fluid supplied from the supply device 6 more than the amount of fluid required by the output mechanism 10; alternatively, the amount of fluid supplied by the supply device 6 needs to be correspondingly reduced.

Two ways of controlling the flow stabilization in a fluid dispensing device are detailed below:

example 1:

referring to fig. 1, a feed pipe 1 is disposed above a ball valve 20, and a discharge pipe 2 is disposed below the ball valve; when the ball valve 20 rotates to a certain angle, the first end 21 is positioned at the top of the ball valve 20 and is opposite to and communicated with the feeding pipe 1, and meanwhile, the second end 22 is positioned at the bottom of the ball valve 20 and is opposite to and communicated with the discharging pipe 2.

When the first channel completely communicates the supply device 6 and the output mechanism 10, the fluid output by the supply device 6 completely flows into the output mechanism 10 through the first channel. The ball valve driving part 4 drives the ball valve 20 to rotate, so that the opening degree of the first end 21 and the feeding pipe 1 is reduced; at the same time, the opening of the second end 22 to the tapping pipe 2 also decreases; in this way, the amount of fluid delivered from the supply device 6 to the first channel is reduced in synchronism with the amount of fluid delivered from the first channel to the delivery mechanism 10 to meet the changing needs of the amount of fluid. Alternatively, when it is desired to increase the amount of fluid in the output mechanism 10, the ball valve driver 4 drives the ball valve 20 to rotate in a reverse direction, so that the first end 21 and the inlet pipe 1 and the second end 22 and the outlet pipe 2 are opened to a greater degree.

In this embodiment, the opening degree of the second end 22 and the opening degree of the discharge pipe 2 and the opening degree of the first end 21 and the feed pipe 1 are increased or decreased synchronously to realize the change of the inlet flow rate of the output mechanism 10.

Example 2:

the fluid distribution device further comprises a return conduit 3; the first channel also comprises a third end 23, and the third end 23 can be communicated with the return pipe 3; when the amount of fluid supplied by the supply device 6 is greater than the inlet flow of the outlet means 10, excess fluid is discharged via the return conduit 3.

Specifically, when the opening of the second end 22 and the outlet pipe 2 is decreased by driving the ball valve 20 to rotate by the ball valve driver 4, the opening of the third end 23 and the return pipe 3 is increased so that more fluid than the output of the outlet pipe 2 is discharged through the return pipe 3. In addition, as the opening of the second end 22 to the tapping pipe 2 increases, the opening of the third end 23 to the return pipe 3 decreases so that more fluid can enter the tapping pipe 2 through the second end 22.

Referring to fig. 2 or 3, at this time, the first passage includes three ports (a first end 21, a second end 22 and a third end 23), which are all opened on the surface of the ball valve 20; wherein, the first end 21 is communicated with the feeding device 6, the second end 22 is communicated with the output mechanism 10, and the third end 23 is communicated with the return pipe 3; that is, the first end 21 of the first channel feeds, the second end 22 feeds, and the third end 23 feeds back. Thus, when the inlet flow of the output mechanism 10 is adjusted, that is, the opening degree of the discharge pipe 2 and the second end 22 is adjusted, so that the amount of fluid output from the first passage to the output mechanism 10 is changed, the third end 23 and the return pipe 3 can coordinate the excess or reduced amount of fluid, thereby ensuring the flow stability in the fluid distribution device.

Specifically, in this embodiment, the flow rate of the fluid output by the supply device 6 is constant and not less than the flow rate required by the output mechanism 10 to work normally; when the device works normally, part of fluid is input into the output mechanism through the discharge pipe 2, and part of fluid is discharged through the return pipe 3; in summary, the flow rate of the feed pipe 1 fed into the first channel is equal to the sum of the flow rate of the discharge pipe 2 and the flow rate of the return pipe 2.

When the flow of the output mechanism 10 needs to be reduced, the opening degrees of the second end 22 and the discharge pipe 2 are reduced, and the opening degrees of the third end 23 and the return pipe 3 are increased; in this way, the amount of fluid fed to the inlet pipe 1 remains constant, but the amount of fluid flowing to the outlet pipe 2 in the first passage decreases, and the amount of fluid flowing to the return pipe 3 increases.

Further, in this embodiment, the opening degree of the first end 21 and the feeding pipe 1 may be always constant, while the opening degree of the second end 22 and the discharging pipe 2 and the opening degree of the third end 23 and the return pipe 3 are varied (when one opening degree is decreased, the other opening degree is increased). For example, referring to fig. 3, the first end 21 is disposed at the lower end of the ball valve 20, and correspondingly, the feeding pipe 1 is disposed below the ball valve 20, opposite to and connected to the first end 21; the ball valve driving piece 4 is connected with the upper end of the ball valve 20, and when the ball valve driving piece 4 drives the ball valve 20 to rotate, the ball valve 20 rotates around the vertical diameter of the ball body; the second end 22 and the third end 23 are arranged on the circumference of a circle formed by the diameters of the sphere in the left-right direction; the discharge pipe 2 and the return pipe 3 are arranged on the outer side of a circle formed by the diameters of the sphere in the left and right directions; the ball valve 20 rotates, and the second end 22 and the third end 23 do circular motion along a circle formed by the diameters of the left and right directions of the ball body; when the ball valve 20 rotates to a certain angle, the second end 22 is communicated with the discharge pipe 2, and the third end 23 is communicated with the return pipe 3. When the fluid flow output by the output mechanism 10 needs to be increased, the opening degree of the second end 22 and the discharge pipe 2 is increased, and the opening degree of the third end 23 and the return pipe 3 is decreased, so that the input amount of the feed pipe 1 is kept unchanged, but the fluid amount flowing into the discharge pipe 2 from the first passage is increased, the fluid flowing into the return pipe 3 is decreased, and the fluid in the first passage flows stably.

Of course, in this embodiment, when the opening degree of one of the second end 22 and the discharging pipe 2, and the opening degree of the third end 23 and the return pipe 3 is increased, and the opening degree of the other is decreased, the opening degree of the first end 21 and the feeding pipe 1 can be changed, as long as the flow rate of the fluid supplied to the first passage by the supplying device 6 through the feeding pipe 1 and the first end 21 is not less than the inlet flow rate required by the output mechanism 10.

As in embodiment 1, the first end 21, the second end 22 and the third end 23 of the first channel may be disposed at any position on the surface of the ball valve 20, as long as the positions of the second end 22 and the third end 23 are changed synchronously during the rotation of the ball valve 20. In addition, discharging pipe 2 is correspondingly arranged on the movement path of second end 22, and return pipe 3 is correspondingly arranged on the movement path of third end 23, as long as the opening degrees of second end 22 and discharging pipe 2 and the opening degrees of third end 23 and return pipe 3 are ensured, and when one of the opening degrees is increased, the other opening degree is correspondingly reduced.

It should be added that the opening degree of the second end 22 and the discharge pipe 2 changes, if the inlet flow of the output mechanism 10 increases, the flow recovered by the return pipe 3 decreases, and the increased flow of the output mechanism 10 is equal to the decreased flow of the return pipe 3. In summary, the flow rate of the feed pipe 1 into the first channel is always equal to the sum of the flow rate of the discharge pipe 2 and the flow rate of the return pipe 2.

It is also to be added that the discharge end of the return pipe 3 may be provided with a storing mechanism (not shown) for storing the fluid recovered via the return pipe 3. Alternatively, the return pipe 3 may be connected to the feeding device 6, and the fluid entering the return pipe 3 through the first passage can flow back to the feeding device 6 to be fed again; when the return pipe 3 is communicated with the feeding device 6, redundant recovered fluid can return to the feeding device 6, and waste is avoided.

In summary, the rotation of the ball valve 20 controls the opening of the port of the first channel and each pipeline in the ball valve 20, so as to conveniently control the fluid flow.

For ease of understanding, the manner of use of a particular fluid distribution device is detailed:

referring to fig. 2, a first passage communicates with the feeding pipe 1, the discharging pipe 2 and the return pipe 3, and the fluid supplied by the supply device 6 enters the output mechanism 10 through the first passage and finally is divided into multiple paths to flow out of each output passage 11. The fluid flow of one output channel 11 is overlarge, and the fluid flow of the other output channels 11 meets the requirement; the output channel 11 for adjusting the excess fluid through the adjusting valve 30 reduces the fluid flow rate finally output; at this time, the amount of fluid fed into the first channel from the feeding pipe 1 is unchanged, and the amount of fluid recovered from the material return pipe 3 is unchanged, so the amount of fluid fed into the output mechanism 10 from the discharging pipe 2 is also unchanged; it is understood that when the fluid amount in one of the output passages 11 becomes smaller, the fluid amount in the other output passage 11 becomes larger. At this time, although the total amount of fluid in the output mechanism 10 is constant, the total pressure of the fluid in the output mechanism 10 changes as one output channel is controlled by the regulating valve 30 to cause a change in the flow rate; the pressure sensor 5 can detect the increase of the pressure in the output mechanism 10 and transmit the change information to the control system; the control system controls the ball valve drive 4 to rotate the ball valve 20 so that the opening of the second end 22 to the tapping pipe 2 is reduced and the opening of the third end 23 to the return pipe 3 is increased in order to reduce the total volume entering the output mechanism 10, while the reduced fluid flow is discharged through the return pipe 3. In this way, the flow rate of the fluid entering the output mechanism 10 is reduced, the pressure sensor 5 can detect that the pressure in the output mechanism 10 is gradually reduced, and when the pressure sensor 5 detects that the pressure in the output mechanism 10 returns to a preset value, the ball valve 20 rotates in place; at this time, the flow rate of the originally excessive output channel 11 becomes small enough to meet the demand, and the other output channels 11 maintain the initial flow rate.

It should be added that, in the actual use process, the flow rate of one of the output channels 11 may not meet the requirement, or the flow rates of a plurality of the output channels 11 may not meet the requirement, and since the regulating valve 30 is arranged on any one of the output channels 11, each output channel 11 is regulated one by one until the flow rate meets the requirement, so that the regulated output channel 11 can accurately operate, and meanwhile, the other output channels 11 which are not regulated continue to accurately operate.

Furthermore, any output channel 11 is also provided with a pressure transmitter 7 which can detect the fluid pressure in the corresponding output channel 11. By providing the independent pressure transmitter 7, the pressure of the fluid finally output from each output channel 11 can be independently monitored, so as to confirm whether the equipment is accurately operated.

The regulating valve 30 is used to regulate the flow of the fluid finally output by the corresponding output channel 11. In one embodiment, the regulating valve 30 can regulate the flow by changing the pipe outlet diameter of the outlet channel 11. For example, the adjusting valve 30 includes a stopper (not shown) and an adjusting drive member (not shown, an automatic drive member such as an air cylinder may be used, or a manual drive member such as a push rod may be used); the blocking piece can extend into the output channel 11 under the driving of the adjusting driving piece and block the fluid from circulating in the output channel 11.

Wherein, the regulating valve 30 can be arranged at the input end of the output channel 11, and the fluid firstly flows through the regulating valve 30 and then enters the output channel 11; alternatively, the regulating valve 30 may be disposed at the output end of the output channel 11, and the fluid flows through the output channel 11, enters the regulating valve 30, and is output again; alternatively, the regulating valve 30 may be provided on the output passage 11, and the fluid may flow through the regulating valve 30 while circulating in the output passage 11.

Referring to fig. 4 and 5, in another embodiment, the regulator valve 30 includes: the valve body is provided with a through second channel 31, and the second channel 31 is communicated with the output channel 11; a seal shaft 32 provided in the valve body and capable of sealing the second passage 31; a working member 33 connected to the seal shaft 32; the sealing shaft (32) moves in the second channel (31) through the driving of the working piece (33); -the fluid flow through the regulating valve (30) increases when the sealing shaft (32) leaves the second passage (31); when the seal shaft (32) penetrates the second passage (31), the flow rate of the fluid flowing through the regulating valve (30) is reduced.

The second channel 31 has at least two ports, one end of which is connected to the output channel 11, and the other end of which is matched to realize the fluid communication. Like the first channel, the second channel 31 may extend linearly, may extend arcuately, and may extend curvilinearly, and the configuration of the second channel 31 is not limited in the present application.

In this embodiment, the working member 33 is a tool convenient for manual operation; an operator can work on the sealing shaft 32 by means of the working member 33, so that the sealing shaft 32 penetrates into the second channel 31, or so that the sealing shaft 32 is distanced from the second channel 31. For example, the main body of the sealing shaft 32 is substantially in the shape of a long rod, the long rod is used for blocking the end part of the second channel 31 and extending into the second channel 31, and the other end of the long rod penetrates out of the valve body and is positioned outside the second channel 31; the working member 33 may be a ball or a block body convenient for a human hand to hold, which is provided on the other end of the seal shaft 32; the operator can pull or push the sealing shaft 32 through the operating member 33 and thus adjust the flow area of the second channel 31.

In this embodiment, the sealing shaft 32 may seal off the port of the second passage 31; alternatively, the seal shaft 32 may close off the flow passage of the second passage 31. Further, a sealing member (e.g., a rubber gasket, a flexible sealing member such as a sealing cavity, etc.) may be disposed at an end of the sealing shaft 32 acting on the second channel 31, so that the sealing shaft 32 can better block the second channel 31; at the same time, the seal prevents fluid from exiting the valve body through the seal shaft 32.

Further, in order to more precisely operate the seal shaft 32, in one embodiment, referring to fig. 5, the working member 33 includes a threaded rod 331 and a hand wheel 332, the hand wheel 332 being connected to the threaded rod 331; a third channel 34 communicated with the second channel 31 is arranged in the valve body, and an internal thread is arranged on the inner wall of the third channel 34; the threaded rod 331 is inserted into the third channel 34 and screwed with the internal thread; by rotating the hand wheel 332, the screwing length of the threaded rod 331 and the internal thread can be adjusted.

By arranging the threaded rod 331 and the internal thread matched with the threaded rod 331, an operator can adjust the screwing length of the threaded rod 331 and the internal thread by rotating the hand wheel 332; therefore, the installation position and the movement direction of the sealing shaft 32 are stable and uniform, and the degree of the sealing shaft 32 extending into the second channel 31 can be adjusted more conveniently and accurately.

In this embodiment, the part of the seal shaft 32 that blocks the second channel 31 passes through the third channel 34 and acts on the second channel 31; at this time, a portion of the sealing shaft 32 penetrating into the second passage 31 may be provided with a sealing member to prevent the fluid from entering the third passage 34.

In order to facilitate the arrangement of the discharge pipe 2 and the regulating valve 30, in a specific embodiment, referring to fig. 5 to 6, the output mechanism 10 includes a manifold block 13, a branch passage 12 is formed in the manifold block 13, and the branch passage 12 is communicated with the discharge pipe 2; any output channel 11 is communicated with a flow dividing channel 12; the pressure sensor 5 can detect the fluid pressure of the branch passage 12.

In this embodiment, the flow dividing channel 12 corresponds to a main line, into which the fluid output by the tapping pipe 2 enters directly; the outlet channels 11 correspond to the shunt tubes, and the fluid in the main duct enters the shunt tubes and is shunted out.

At this time, the pressure sensor 5 is connected to the shunt passage 12; for example, referring to fig. 6, the flow dividing channel 12 is a pipe extending in the vertical direction in the manifold block 13, and the pressure sensor 5 is provided below the manifold block 13, and has a detection end communicating with the flow dividing channel 12, and is capable of detecting the total pressure of the fluid in the output mechanism 10.

By providing the manifold block 13, on the one hand, the branching passage 12 and the output passage 11 can be opened easily. On the other hand, a plurality of ports for communicating the output channel 11 may be formed on the manifold block 13, and not every port is used in the actual use process; for example, referring to fig. 6, the manifold block 13 is shown with six ports, but two middle ports are sealed and not connected to the output channel 11; it is easy to understand that by providing a plurality of ports, the available ports can be selected according to the use requirement to improve the applicability of the device.

Further, by providing the manifold block 13, it is also possible to facilitate installation of the regulating valve 30. Referring to fig. 5 and 6, the regulating valve 30 is provided on the manifold block 13; one end of the regulating valve 30 is communicated with the flow dividing channel 12, and the other end is communicated with the output channel 11.

With further reference to fig. 6, at this time, the second passage 31 includes a vertical section communicating with the flow dividing passage 12 and a horizontal section communicating with the output passage 11; the third channel 34 is arranged at the upper end of the valve body and is communicated with the second channel 31; the sealing shaft 32 can move in the vertical direction under the action of the working piece 33 to block the connecting position of the vertical section and the horizontal section of the second channel 31.

Furthermore, in order to conveniently arrange the output channel 11, the output mechanism 10 further comprises a mounting block 14, the mounting block 14 is arranged on one side of the manifold block 13, and the output channel 11 is arranged on the mounting block 14 in a penetrating way; the mounting block 14 can facilitate the interval arrangement of a plurality of output channels 11 and avoid the mutual interference of the output channels 11. Meanwhile, when any output channel 11 is correspondingly provided with the pressure transmitter 7, the installation block 14 can also facilitate the installation of the pressure transmitter 7.

The application also discloses a coating device, which comprises the fluid distribution device; wherein, the feeding device 6 is used for feeding slurry required by coating; slurry enters the output mechanism 10 through the feeding pipe 1, the first channel and the discharging pipe 2; because the output mechanism 10 comprises at least two output channels 11, the slurry entering the output mechanism 10 is divided into at least two paths and then output, and at least two material layers can be coated on the base material.

The coating equipment is mainly used for coating slurry (such as a conductive material) on the surface of a substrate (such as copper material or foil). In some embodiments, the substrate surface is coated with only one layer (e.g., the substrate surface is filled with slurry), and in this case, the plurality of output channels 11 of the fluid distribution device can be arranged side by side to connect the output slurry into a whole. In other embodiments, the substrate is coated with multiple layers (e.g., zebra stripes on the substrate), and the multiple output channels 11 of the fluid distribution device can be spaced apart. Alternatively, the plurality of outlet channels 11 of the fluid distribution device may be arranged partially at intervals and partially side by side, as required. The present application does not specifically limit the arrangement position and the relative position relationship of the output channel 11.

In addition, when coating, the thickness of the material layer on the base material has certain process requirements; as will be readily appreciated, the thickness of the bed is related to the flow rate of the slurry out of the outlet channel 11. By arranging the fluid distribution device, the output channel 11 with inaccurate output quantity can be conveniently adjusted according to the process requirement, and the output quantity is increased or reduced to meet the thickness requirement of coating. At this time, the flow rate change in any output channel 11 causes the fluid pressure change in the entire output mechanism 10, and the feedback of the pressure sensor 5 and the adjustment of the electric ball valve (the ball valve 20 and the ball valve driving member 4) can maintain the total fluid pressure in the output mechanism 10 unchanged, thereby ensuring that other output channels 11 which are not adjusted are not affected by the adjustment, and ensuring the stable operation of the fluid application equipment.

Further, the output channel 11 communicates with the coating head 8, and the slurry is coated on the substrate via the coating head 8.

The number of the coating heads 8 can be multiple, and each coating head 8 is independently communicated with the corresponding output channel 11; at this time, slurry supplied by the supply device 6 passes through the feed pipe 1, the first channel and the discharge pipe 2, is divided into a plurality of channels in the output mechanism 10, and enters the corresponding coating heads 8 through the output channels 11; any applicator head 8 is capable of independently drawing a layer of material onto the substrate.

Alternatively, the number of the coating heads 8 may be one, and a plurality of independent coating channels are arranged in one coating head 8, and each coating channel is correspondingly communicated with one output channel 11 so as to independently receive the slurry and output the slurry to the substrate.

Through setting up coating head 8, can inject coating shape and coating position according to the coating needs, conveniently accomplish the coating to the substrate. The specific configuration of the coating head 8 is prior art and will not be described in detail here.

Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. Such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may alternatively include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
