Technical Field

[0001] This invention relates to the field of adhesive application technology for flow batteries, and more particularly to an adhesive application device for applying adhesive to the surface of flow batteries. Background Technology

[0002] Flow batteries, with their advantages of high energy conversion efficiency, long service life, environmental friendliness, customizable capacity, and high safety, have become one of the main energy storage methods for renewable energy sources such as wind and solar power, as well as for peak shaving and valley filling of electricity. The flow battery graphite plate three-in-one module adopts a unique three-in-one process, integrating multiple components of a traditional fuel cell stack into a single unit. This simplifies the stack assembly process, enables modular management, and significantly improves maintenance efficiency, reduces maintenance costs, and ensures product stability and reliability.

[0003] In existing technologies, the printing head is equipped with only a single set of glue channels and a single specification of glue dispensing pad during production, enabling it to output only one size of glue line and adapting only to a single model of three-in-one electrode plate. When enterprises produce multiple models and capacities of flow batteries on the same production line, they need to equip multiple sets of printing head tooling with different specifications; when switching product models, the entire printing head, pad, and glue dispensing flow rate and alignment accuracy need to be disassembled and replaced, making the model changeover process cumbersome, the downtime for debugging long, the production line inflexible, and the tooling procurement, storage, and maintenance costs high.

A pair of spaced gasket strips are slidably mounted on the bottom of the gasket mounting strip. The distance between the two gasket strips is adjustable. A sliding protrusion is formed on the top of the gasket strip. A sliding groove is formed along the length of the gasket mounting strip to guide the sliding protrusion to slide.

[0006] Furthermore: the sealing plate is divided into a first sealing plate installed on the outside of the first-sized gasket and a second sealing plate installed on the outside of the second-sized gasket; the first glue channel is formed on the glue outlet, the second glue channel is formed on the second sealing plate, and the other end of the second pipeline system is connected to the second sealing plate.

[0007] Furthermore: the thickness of the gasket mounting strip is the same as the thickness of the gasket strip, and the sliding protrusion is fitted with a soft sealing plug to block the sliding groove.

[0008] Furthermore: the first sealing plate has a guide groove formed along its length, and a first sliding block and a second sliding block are slidably installed in the guide groove. A connecting post is installed on the gasket strip, and the first sliding block and the second sliding block are respectively connected to the corresponding connecting post. The first sliding block slidably drives one of the gasket strips to move, and the second sliding block slidably drives the other gasket strip to move.

[0009] Furthermore: the inner ends of the first sliding block and the second sliding block are respectively equipped with guide connecting strips, the guide connecting strips are connected to the corresponding connecting posts, the top of the guide connecting strip is formed with a concave first sealing groove, and the bottom of the guide connecting strip is formed with a raised second sealing protrusion.

[0010] Furthermore, the guide groove is provided with a sealing structure, which includes a first sealing connecting strip formed on the top of the guide groove and a second sealing connecting strip formed on the bottom of the guide groove. Both the first and second sealing connecting strips are arranged along the length of the guide groove, and the guide connecting strip slides in cooperation with both the first and second sealing connecting strips.

[0011] Furthermore: the first sealing groove of the guide connecting strip slides into the bottom of the first sealing connecting strip, and the second sealing connecting strip is formed with a second sealing groove that slides into the second sealing protrusion at the bottom of the guide connecting strip; the first sealing connecting strip is in contact with the surface of the first sealing groove, and the second sealing connecting strip is in contact with the surface of the second sealing groove.

[0012] Furthermore: the cross-section of the dispensing seat is an inverted triangle, and the first-sized shim and the second-sized shim are installed in a V-shape on the dispensing seat.

One set of equipment can accommodate flow battery three-in-one plates of different shapes and sealing widths, eliminating the need to purchase and assemble dedicated dispensing heads for different plate models, thus reducing investment in production line tooling and spare parts inventory costs. By sliding the gasket strips, the distance between the two gasket strips in the first-size gasket is adjustable, allowing for adjustment of the opening size of the first-size gasket. When dealing with flow batteries of different sizes, one dispensing head can accommodate more flow battery three-in-one plates with wider borders and sealing edge sizes, reducing the number of spare gaskets required. There is no need to replace the dispensing head or disassemble the first-size gasket, further reducing spare parts procurement and inventory costs. Attached Figure Description

Detailed Implementation

[0025] The present invention will now be described in detail with reference to the accompanying drawings.

[0026] like Figure 1-7 As shown, the adhesive application device for applying adhesive to the surface of a flow battery includes an adhesive application base 1, with an adhesive dispensing head installed at the bottom of the base 1. The adhesive application base 1 is provided with a first pipeline system 17 and a second pipeline system 18. A three-way connector 12 is also provided inside the adhesive application base 1. The three-way connector 12 includes an inlet 15, a first port 13 communicating with the first pipeline system 17, and a second port 14 communicating with the second pipeline system 18. The adhesive dispensing head includes an adhesive dispensing base 2. A first-sized gasket 21 is installed on the front end face of the dispensing base 2, and a second-sized gasket 22 is installed on the rear end face of the dispensing base 2. Sealing plates are respectively installed on the outside of the first-sized gasket 21 and the second-sized gasket 22. A first adhesive channel 23 is formed inside the dispensing base 2, and a second adhesive channel 24 is formed on the sealing plate connected to the second-sized gasket 22. The first pipeline system 17 is connected to the first adhesive channel 23, and the second pipeline system 18 is connected to the second adhesive channel 24.

[0027] The top of the printing base 1 is formed with a top mounting hole 11. The printing base 1 is mounted on the drive end of the printing robot through the top mounting hole 11, which ensures that the printing base 1 can move in multiple directions to match the position of the flow battery.

[0028] The dispensing head is equipped with two sizes of gaskets. By controlling the UV adhesive feed to the three-way connector 12, it then branches to the first pipeline system 17 and the second pipeline system 18, respectively supplying adhesive to the first-size gasket 21 or the second-size gasket 22 for dispensing. This allows for dispensing and printing of adhesive in two sizes, accommodating different flow battery sizes. One set of equipment can adapt to three-in-one flow battery plates of different shapes and sealing widths, eliminating the need to purchase and assemble dedicated dispensing heads for different plate models, thus reducing investment in production line tooling and spare parts inventory costs.

[0029] Specifically, the first-size gasket 21 includes a horizontally arranged gasket mounting strip 3. A pair of spaced-apart gasket strips 31 are slidably mounted on the bottom of the gasket mounting strip 3. The distance between the two gasket strips 31 is adjustable. A sliding protrusion 32 is formed on the top of the gasket strip 31. A sliding groove 33 is formed along the length of the gasket mounting strip 3 to guide the sliding protrusion 32. By sliding the gasket strips 31, the distance between the two gasket strips 31 can be adjusted, making the opening size of the first-size gasket adjustable. When dealing with flow batteries of different sizes, one printing head can be adapted to flow battery three-in-one plates with more frame widths and sealing edge sizes, reducing the number of spare gasket tooling, eliminating the need to replace the printing head, and eliminating the need to disassemble the first-size gasket, thus reducing spare parts procurement and inventory costs.

[0030] Specifically, the sealing plate is divided into a first sealing plate 25 installed on the outside of the first size gasket 21 and a second sealing plate 26 installed on the outside of the second size gasket 22; the first glue channel 23 is formed on the glue outlet 2, the second glue channel 24 is formed on the second sealing plate 26, and the other end of the second pipeline system 18 is connected to the second sealing plate 26.

[0031] The glue from the first pipeline system 17 flows into the first glue channel 23 inside the glue outlet 2, and then flows downward through the first glue gasket to the bottom of the glue outlet 2, forming a first-size glue printing operation; the glue from the second pipeline system 18 flows into the first glue channel 23 inside the second sealing plate 26, then overflows into the first glue gasket, and flows downward to the bottom of the glue outlet 2, forming a second-size glue printing operation.

[0032] In addition, the first sealing plate 25 is fixedly connected to the front end face of the dispensing seat 2, the first size gasket 21 is clamped between the first sealing plate 25 and the dispensing seat 2, the second sealing plate 26 is fixedly connected to the rear end face of the dispensing seat 2, and the second size gasket 22 is clamped between the second sealing plate 26 and the dispensing seat 2. The glue overflowing onto the surface of the dispensing seat 2 can flow downwards until the printing port structure at the bottom of the dispensing seat 2. The printing port structure is formed by the dispensing seat 2, the bottom of the first size gasket 21, and the bottom of the second size gasket 22.

[0033] Furthermore, the printing plate holder 1 is equipped with a control valve 16, which is connected to the tee connector 12. The control valve 16 controls the flow direction of the adhesive into the tee connector 12, selecting whether the adhesive flowing into the tee connector 12 is directed to the first port 13 or the second port 14. By directly regulating the internal fluid flow of the tee connector 12 through the control valve 16, the production line PLC program can be electrically controlled to automatically switch the adhesive flow direction to the first pipeline system 17 or the second pipeline system 18 according to the model of the electrode plate to be processed.

[0034] Preferably, control valve 16 is a ball valve pneumatic control valve. The ball valve achieves on / off switching by rotating a 90° ball-shaped valve core. The valve core and valve seat have a hard metal seal, providing a zero-gap seal when closed, preventing UV adhesive from penetrating. Furthermore, the first-sized gasket 21 is installed on the front end face, and the second-sized gasket 22 is installed on the rear end face. The bottom of the first-sized gasket 21 and the bottom of the second-sized gasket 22 converge at the bottom of the glue outlet 2. The bottom of the first-sized gasket 21 is formed with a first glue outlet groove 27 for glue to overflow, and the bottom of the second-sized gasket 22 is formed with a second glue outlet groove 28 for glue to overflow.

[0035] The first glue channel 23 connects to the first-sized gasket 21 at the front end; the second glue channel 24 connects to the second-sized gasket 22 at the rear end; the bottoms of the first-sized gasket 21 and the second-sized gasket 22 converge at the same glue application surface at the bottom of the glue outlet 2. The glue can only be extruded directionally downwards from the bottom opening, effectively preventing the glue from overflowing laterally to the sides of the gasket and the non-sealed area of ​​the electrode plate. This avoids UV glue overflowing into the conductive area of ​​the electrode plate, preventing poor insulation of the electrode plate. It solves the technical problems of the traditional split-type dual glue outlet structure, such as misalignment of the two glue outlets, inconsistent reference, and the need to readjust the height and alignment coordinates of the printing head when changing models, resulting in cumbersome machine setup and time-consuming model changeovers.

[0036] Preferably, the cross-section of the dispensing seat 2 is an inverted triangle, and the first-sized gasket 21 and the second-sized gasket 22 are installed in a V-shape on the dispensing seat 2. The opening sizes of the first dispensing slot 27 and the second dispensing slot are different. By setting the cross-section of the dispensing seat 2 to an inverted triangle, the first-sized gasket 21 and the second-sized gasket 22 are installed in a V-shape on both sides of the dispensing seat 2, forming a beveled fit, bidirectional limiting, and self-centering assembly. Under the same printing head and the same processing benchmark, two standard sealing glue lines of different widths and thicknesses can be accurately output, which can accurately match their exclusive sealing process requirements. The small-sized opening is suitable for narrow-edge sealing plates, and the large-sized opening is suitable for wide-edge sealing plates. One set of tooling can cover the production needs of multiple product models, greatly improving the equipment's versatility and the production line's flexible production capabilities.

[0037] It should be noted that the first dispensing slot 27 and the second dispensing slot are flow spaces where glue overflows from corresponding channels. For example, the first dispensing slot 27 is formed between the dispensing seat 2 and the first sealing plate 25. The slot space formed by the first dispensing slot 27 allows the glue from the first glue channel 23 to flow out. The dispensing point of the first glue channel 23 has a first dispensing groove 29, which is an elongated groove structure formed on the front end face of the dispensing seat 2. The first dispensing groove 29 is exactly aligned with the first dispensing slot 27. After the glue from the first glue channel 23 flows out, it can flow downwards along the first dispensing slot 27, cooperating with the glue application opening structure at the bottom of the dispensing seat 2 to form the first width and thickness of the printing process. Conversely, the second dispensing slot 28 is formed between the dispensing seat 2 and the second sealing plate 26. The groove space formed by the second glue outlet groove 28 allows the glue from the second glue channel 24 to flow out. The glue outlet of the second glue channel 24 is formed with a second glue outlet groove 30. The second glue outlet groove 30 is a long groove structure and is formed on the front end face of the second sealing plate 26. The second glue outlet groove 30 is exactly aligned with the second glue outlet groove 28. After the glue from the second glue channel 24 flows out, it can flow downward along the second glue outlet groove 28. Together with the glue application opening structure at the bottom of the glue outlet seat 2, a second width and thickness of glue printing process is formed.

[0038] Specifically, the first piping system 17 includes a first pipe joint 171 installed at the outer end of the first glue flow channel 23, and a first glue supply pipe 172 installed between the first pipe joint 171 and the first port 13; the second piping system 18 includes a second pipe joint 181 installed at the outer end of the second glue flow channel 24, and a second glue supply pipe 182 installed between the second pipe joint 181 and the second port 14.

[0039] In this embodiment, the first pipeline system 17 is equipped with a dedicated first pipe connector 171 and a first glue supply pipe 172, which are separately connected to the first port 13 of the tee connector 12 and the first glue flow channel 23. The second pipeline system 18 is equipped with a dedicated second pipe connector 181 and a second glue supply pipe 182, which are independently connected to the second port 14 of the tee connector 12 and the second glue flow channel 24. This allows the two glue streams to form a dedicated, segmented, and non-shared flow path from the branching end, the delivery end to the glue outlet. When one of the pipelines experiences glue buildup on the inner wall, minor blockage, or aging and leakage at the connector, the corresponding pipe and pipe connector can be disassembled separately for cleaning and replacement without disassembling core precision components such as the printing plate 1, the glue outlet 2, and the tee connector 12, thus not interfering with the normal use of the other intact glue path.

[0040] Specifically, the first-size gasket 21 includes a horizontally arranged gasket mounting strip 3. A pair of spaced-apart gasket strips 31 are slidably mounted on the bottom of the gasket mounting strip 3. The distance between the two gasket strips 31 is adjustable. A sliding protrusion 32 is formed on the top of the gasket strip 31. A sliding groove 33 is formed along the length of the gasket mounting strip 3 to guide the sliding protrusion 32. By sliding the gasket strips 31, the distance between the two gasket strips 31 can be adjusted, making the opening size of the first-size gasket adjustable. When dealing with flow batteries of different sizes, one printing head can be adapted to flow battery three-in-one plates with more frame widths and sealing edge sizes, reducing the number of spare gasket tooling, eliminating the need to replace the printing head, and eliminating the need to disassemble the first-size gasket, thus reducing spare parts procurement and inventory costs.

[0041] Furthermore, the thickness of the gasket mounting strip 3 is the same as that of the gasket strip 31, and the sliding protrusion 32 is fitted with a soft sealing plug 34 to block the sliding groove 33. The gasket mounting strip 3 and the gasket strip 31 have the same thickness, and after assembly, their outer surfaces are flush without any uneven steps. The entire gasket fits tightly against the first sealing plate 25 without any stepped assembly gaps. The soft sealing plug 34 is fitted at the sliding protrusion 32, and the sealing plug slides synchronously with the sliding protrusion 32 in the sliding groove 33, filling the groove gap throughout the entire process to prevent glue from overflowing from the side.

[0042] The first sealing plate 25 has a guide groove 35 formed along its length. A first sliding block 36 and a second sliding block 37 are slidably installed in the guide groove 35. A connecting post 38 is installed on the gasket strip 31. The first sliding block 36 and the second sliding block 37 are respectively connected to the corresponding connecting post 38. The first sliding block 36 slidably drives one of the gasket strips 31 to move, and the second sliding block 37 slidably drives the other gasket strip 31 to move. When adjusting the opening width of the first-sized gasket, it is not necessary to disassemble the sealing plate or the printing head as a whole. The two gasket strips 31 can be independently controlled to move by simply moving the sliding block on the outside of the tooling. Changeover and fine-tuning operations do not require stopping the machine to disassemble complex components, which greatly reduces the time spent on specification adjustment.

[0043] In one embodiment, if the two sliding blocks are moved synchronously in the same direction, the two gasket strips 31 will move synchronously to keep the adhesive line centered. This is suitable for conventional working conditions where only the adhesive line is widened or narrowed as a whole, and the centering of the electrode seal remains unchanged. If a single sliding block is moved, only one side of the gasket strip 31 will be displaced, achieving micro-adjustment of the adhesive line on one side. This can be adapted to special flow battery electrode plate processes with single-sided offset of the electrode plate frame and non-standard eccentric sealing, providing greater adjustment freedom and covering more non-standard customized products.

[0044] The guide groove 35 provides lateral constraint on the sliding of the first sliding block 36 and the second sliding block 37. The sliding blocks can only move in a straight line along the groove. The connecting column 38 rigidly drives the shim strip 31 to move laterally, restricting the shim strip 31 from tilting up and down or deflecting back and forth throughout the process. After adjustment, the shim strip 31 always remains straight, with parallel edges on both sides, and the glue outlet is a regular rectangle, without any oblique glue lines that are wider on one side and narrower on the other. During mass production, when subjected to continuous impact from the glue and reciprocating vibration of the equipment, the sliding blocks are limited and locked by the guide groove, and the shim spacing will not drift on its own, maintaining the consistency of glue line dimensions over a long period and reducing the rate of defective products with out-of-tolerance dimensions.

[0045] Furthermore, guide connecting strips 40 are respectively installed on the inner ends of the first sliding block 36 and the second sliding block 37. The guide connecting strips 40 are connected to the corresponding connecting posts 38. The top of the guide connecting strip 40 is formed with a concave first sealing groove 41, and the bottom of the guide connecting strip 40 is formed with a raised second sealing protrusion 42. The guide groove 35 is provided with a sealing structure 4, which includes a first sealing connecting strip 43 formed on the top of the guide groove 35 and a second sealing connecting strip 44 formed on the bottom of the guide groove 35. The first sealing connecting strip 43 and the second sealing connecting strip 44 are both arranged along the length of the guide groove 35, and the guide connecting strip 40 slides in cooperation with both the first sealing connecting strip 43 and the second sealing connecting strip 44.

[0046] When the sliding block moves, the guide connecting strip 40 is simultaneously constrained by the upper and lower sealing connecting strips, and can only move linearly along the guide groove 35. After adjustment, the edges of the two gasket strips 31 always remain parallel, and the glue outlet opening is regular. In addition, the guide connecting strip 40 and the guide groove 35 rely on the first sealing groove 41 and the first sealing connecting strip 43, and the second sealing protrusion 42 and the second sealing connecting strip 44 to form a pair of continuous dynamic sealing surface structures along the entire length of the guide groove 35. The upper and lower seals cooperate to prevent glue from entering the first sealing plate from the front end of the glue outlet seat, achieving bidirectional sealing and internal and external isolation. No matter how the first sliding block 36 and the second sliding block 37 move, the guide connecting strip 40 connected to the sliding block is always in contact with the first sealing connecting strip 43 and the second sealing strip 44, forming the sealing structure 4.

[0047] Furthermore, the first sealing groove 41 of the guide connecting strip 40 slides with the bottom of the first sealing connecting strip 43, and the second sealing connecting strip 44 is formed with a second sealing groove 45 that slides with the second sealing protrusion 42 at the bottom of the guide connecting strip 40; the first sealing connecting strip 43 is in surface contact with the first sealing groove 41, and the second sealing connecting strip 44 is in surface contact with the second sealing groove 45. The first sealing connecting strip 43 and the first sealing groove 41, and the second sealing protrusion 42 and the second sealing groove 45 slide in full surface contact. During sliding adjustment, the groove walls of the first sealing connecting strip 43 and the second sealing connecting strip 44 can simultaneously scrape off the trace amount of UV residue adhering to the surface of the guide connecting strip 40. The residue is blocked on the outside of the sealing pair and cannot enter the sliding fit gap.

[0048] Furthermore, even if some glue enters the inner side of the first sealing strip 43 and the second sealing strip 44, it will not affect the normal offset printing process. The sealing structure 4 is set up to prevent a large amount of glue from overflowing and to ensure the normal operation of the printing process.

[0049] It should be noted that the first sealing plate 25 includes an upper plate 46 and a lower plate 47. The upper plate 46 and the lower plate 47 are installed together by bolts and a slot structure. The guide groove 35 serves as a dividing line. When it is necessary to clean the glue residue in the first sealing plate, the upper plate 46 and the lower plate 47 can be separated. The guide groove 35 is exposed and open at this time, which makes it easy for the staff to remove the residual glue and complete the cleaning. In addition, the connection between the first size gasket and the first sliding block 36 can be separated and disassembled, and the first size gasket that is severely worn or structurally damaged can be disassembled and replaced.

[0050] In summary, the present invention possesses the excellent characteristics described above, which enhances its effectiveness in use compared to previous technologies, making it a highly practical product.

[0051] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
