Description

Technical Field

[0001] This utility model relates to the field of electroplating technology, specifically to a conveying mechanism for electroplating equipment and electroplating equipment. Background Technology

[0002] Existing electroplating equipment typically employs roller or steel belt conveyors combined with water-blocking components (such as baffles or rollers) to prevent electroplating solution from overflowing into the conveying channel. However, these water-blocking components only physically limit the spread of the electroplating solution but cannot actively recover spilled liquid. When glass substrates enter or exit the electroplating tank, the electroplating solution easily drips along the edges into the conveying channel, contaminating the surface of the glass substrates. Furthermore, the overflowing liquid further drips into the equipment, requiring frequent manual cleaning, thus increasing maintenance costs.

[0003] Furthermore, existing technologies lack efficient recovery paths for overflow liquids, resulting in direct contact between the electroplating solution and the material surface, damaging its functional coating. Traditional conveying devices are prone to corrosion due to liquid residue, further shortening their service life. These shortcomings indicate significant deficiencies in existing conveying mechanisms for electroplating solution management, necessitating an improved solution that can dynamically recover overflow liquids, protect material surface quality, and reduce maintenance costs. Utility Model Content

[0004] In view of this, the present invention provides a conveying mechanism and an electroplating device to solve the problem of overflow liquid during material entry and exit in related technologies.

[0005] In a first aspect, this utility model provides a conveying mechanism for an electroplating equipment, comprising:

[0006] The housing has a first material inlet, a conveying channel, and a second material inlet connected in sequence, wherein the second material inlet is adjacent to and connected to the electroplating tank of the electroplating equipment;

[0007] A conveying device is installed in the conveying channel and is used to convey materials from the first feed port to the second feed port. A water-blocking component is provided between the conveying device and the second feed port, and a passage gap is defined in the water-blocking component for the material to pass through.

[0008] The suction knife assembly includes a pump body, a liquid suction pipe, and a suction knife body connected in sequence. The suction knife body is installed between the conveying device and the second feed port and is located adjacent to the water blocking assembly. The water suction port of the suction knife body is connected to the through gap.

[0009] Beneficial effects: The conveying mechanism of the electroplating equipment according to the embodiments of this utility model, by introducing a suction knife assembly and its dynamic communication design with the through gap, solves the defects of existing electroplating equipment conveying mechanisms in terms of overflow recovery, material contamination control, and maintenance costs. The specific advantages are as follows:

[0010] (1) The suction knife assembly of this utility model drives the liquid suction pipe through the pump body to form a negative pressure in the suction knife body, and directly recovers the overflow liquid through the water suction port and the gap. This design can dynamically adapt to the liquid dripping generated during the material movement, avoid liquid contamination of the material surface, and significantly reduce the risk of uneven coating or corrosion.

[0011] (2) The suction knife assembly of this utility model can immediately recover the overflow liquid when the material passes through the gap, ensuring the cleanliness of the material surface. It is especially suitable for materials such as glass substrates or thin circuit boards that are sensitive to surface quality.

[0012] (3) The novel suction knife assembly uses a negative pressure recovery mechanism to concentrate the overflow liquid into the pump body and return it to the electroplating tank or treatment system, which greatly reduces the situation of liquid dripping into the equipment, extends the service life of the equipment and reduces the need for manual intervention.

[0013] (4) The suction knife body of this utility model is installed between the conveying device and the second material port and adjacent to the water blocking component. Its suction port directly faces the passage gap, which can respond to the material movement trajectory in real time, efficiently recover the overflow liquid, and avoid liquid residue or diffusion.

[0014] In one optional embodiment, the water-blocking assembly includes at least two sets of water-blocking rollers, with two water-blocking rollers in the same set arranged opposite each other and defining the passage gap, and the water-blocking rollers in different sets arranged at intervals along the material conveying direction, and an installation gap communicating with the passage gap is defined between every two adjacent sets of water-blocking rollers.

[0015] The suction knife body extends into the installation gap and communicates with the passage gap through the suction port.

[0016] Beneficial effects: The combination of the passage gap and installation gap of the baffle roller assembly ensures smooth material transport and provides a directional recovery path for overflow liquid, preventing liquid from spreading to other areas of the conveying channel. Furthermore, the suction knife body is directly embedded in the installation gap, and the suction port is connected to the passage gap, allowing for real-time recovery of overflow liquid and preventing liquid contamination of the material surface or entry into subsequent processes.

[0017] In one optional embodiment, the suction knife body includes a suction knife base and a plurality of suction knife blades. The suction knife base is connected to the liquid suction pipe. The suction knife blades protrude from the surface of the suction knife base and extend into the installation gap, with one end of the suction knife blade adjacent to the through gap forming the water suction port.

[0018] Beneficial effects: The embedded layout and multi-blade design of the suction blade significantly improve liquid recovery efficiency and reduce the risk of overflow liquid contaminating the material surface. Simultaneously, the protruding structure of the suction blade directly contacts the overflow liquid, preventing increased equipment operating resistance due to liquid accumulation and ensuring stable operation of the conveying device.

[0019] In one alternative embodiment, a groove is formed on the side surface of the suction knife seat facing the water-blocking roller, the shape of the groove matching the shape of the water-blocking roller, and the water-blocking roller being fitted into the groove with a clearance.

[0020] Beneficial effects: This utility model achieves the dual goals of precise installation of the suction knife body and free rotation of the water-blocking roller through the synergistic design of the groove and the clearance fit. On the one hand, the groove ensures the positioning stability of the suction knife body in the conveying channel, avoiding liquid recovery failure due to installation deviation; on the other hand, the clearance fit eliminates the frictional resistance of the water-blocking roller during rotation by reserving controllable space, while ensuring its functional integrity.

[0021] In one optional embodiment, the suction blade body is fitted within the mounting gap and spans the entire mounting gap, both the suction blade body and the suction port extend along the length direction of the mounting gap, and the width of the suction port is smaller than the width of the suction blade body.

[0022] Beneficial effects: This utility model achieves synergistic optimization of structural stability and liquid recovery efficiency through the differentiated width design of the suction blade and the suction port, combined with the dynamic adaptability of the gap fit. Specifically, the wide coverage of the suction blade can provide structural support and liquid guidance, ensuring the stability of equipment operation; the narrow design of the suction port can accurately recover liquid in key overflow areas, improve liquid recovery efficiency and reduce the risk of mechanical interference.

[0023] In one optional embodiment, the suction knife seat extends along the length direction of the installation gap, and the side surface of the suction knife seat opposite to the water-blocking roller is provided with a plurality of water outlet interfaces connected to the liquid suction pipe. Each group of water outlet interfaces includes a plurality of water outlet interfaces connected to the same water suction port, and the plurality of water outlet interfaces in the same group are arranged at intervals along the length direction of the installation gap.

[0024] Beneficial effects: The above embodiments, through the extended design of the suction base and the grouping and spacing of the water outlet interfaces, achieve high efficiency, reliability, and adaptability of the liquid recovery system. Specifically, the extension of the suction base ensures that the suction port and water outlet interface cover the entire installation gap, thereby improving the comprehensiveness of liquid recovery; while the grouping and spacing of the water outlet interfaces disperses liquid pressure, balances flow, reduces the risk of clogging, and thus extends equipment life.

[0025] In one optional embodiment, the conveying device includes a plurality of conveying rollers spaced apart along the material transport direction. Each conveying roller is provided with a first roller, a third roller, and a second roller in sequence along its length direction. The first roller, the second roller, and the third roller are respectively used to contact the ineffective area of ​​the glass substrate and support the glass substrate.

[0026] Beneficial Effects: This invention solves the stability problem of traditional single-point or double-point support systems during glass substrate transportation by employing a three-roller segmented support and ineffective area contact strategy. The multi-point support structure disperses weight pressure, preventing glass breakage; while the roller-contact-ineffective-area support method protects the quality of the effective area, thereby reducing the risk of contamination. Furthermore, this invention can adapt to glass substrates of different sizes (such as varying aspect ratios) by adjusting the roller spacing, thus improving the equipment's versatility.

[0027] In one alternative embodiment, a first baffle is provided on the side of the first roller away from the third roller, and a second baffle is provided on the side of the second roller away from the third roller.

[0028] Beneficial effects: The first and second baffles can limit the lateral movement of the glass substrate during transportation, preventing it from deviating from the predetermined path. Simultaneously, the segmented support of the glass ineffective areas by three rollers further enhances the stability and safety of the overall transportation process. Furthermore, the baffle structure is simple, easy to install and maintain, and suitable for conveying glass substrates of various sizes.

[0029] In one optional embodiment, a first elastic washer is fitted on the outer side of the first roller, a second elastic washer is fitted on the outer side of the second roller, and a third elastic washer is fitted on the outer side of the third roller.

[0030] Beneficial effects: The elastic washer acts as a buffer between the roller and the glass substrate, reducing the risk of impact or scratches from rigid contact. Simultaneously, the elastic washer surface has a certain coefficient of friction, which increases the friction between the roller and the ineffective area of ​​the glass, preventing slippage and ensuring smooth glass transport.

[0031] Secondly, this utility model also provides an electroplating apparatus, comprising:

[0032] The conveying mechanism of the electroplating equipment as described in the first aspect of this utility model;

[0033] The electroplating tank has two conveying mechanisms, which are located upstream and downstream of the electroplating tank respectively and are connected to the electroplating tank through the second feed port.

[0034] Beneficial effects: On the one hand, the above structure effectively prevents the electroplating solution from overflowing both upstream and downstream of the electroplating tank, ensuring a clean workshop environment and safe operation; on the other hand, the upstream conveying mechanism can clean the materials during the pretreatment stage through the suction knife assembly, ensuring that there is no residual liquid before the materials enter the electroplating tank, thus protecting the purity of the electroplating solution; while the downstream conveying mechanism can prevent pollution and recycle the electroplating solution after electroplating through the suction knife assembly, reducing the pollution risk of subsequent processes and realizing resource recycling.

[0055] The following description, with reference to the accompanying drawings, illustrates a conveying mechanism 100 and an electroplating device according to the present invention. It should be noted that the electroplating device includes an electroplating tank 200 and at least one of the aforementioned conveying mechanisms 100. The conveying mechanism 100 is used to convey material 5 into the electroplating tank 200 to achieve electroplating.

[0056] like Figures 1 to 11 As shown, the conveying mechanism 100 of the electroplating equipment according to the first aspect of the present invention includes a housing 1, a conveying device 2, and a suction knife assembly.

[0057] The housing 1 has a first feed port 11, a conveying channel 13, and a second feed port 12 connected in sequence, wherein the second feed port 12 is adjacent to and connected to the electroplating tank 200 of the electroplating equipment. The conveying device 2 is installed in the conveying channel 13 and is used to convey the material 5 from the first feed port 11 to the second feed port 12. A water-blocking component is provided between the conveying device 2 and the second feed port 12, and the water-blocking component defines a passage gap 32 for the material 5 to pass through.

[0058] The suction knife assembly includes a pump body 41, a liquid suction pipe 42 and a suction knife body 43 connected in sequence. The suction knife body 43 is installed between the conveying device 2 and the second material port 12 and is located adjacent to the water blocking assembly. The water suction port 433 of the suction knife body 43 is connected to the passage gap 32.

[0059] The specific structure of the conveying mechanism 100 of the electroplating equipment according to an embodiment of the present utility model is described below:

[0060] The housing 1 has a first inlet 11, a conveying channel 13, and a second inlet 12 connected in sequence. The first inlet 11 is the input end of material 5, the conveying channel 13 is the transmission path of material 5, and the second inlet 12 is the output end, directly connected to the electroplating tank 200. The housing 1 provides a closed installation space for the conveying device 2, the water-blocking assembly, and the suction knife assembly, preventing external contaminants from entering. On the other hand, the communication between the housing 1 and the electroplating tank 200 through the second inlet 12 ensures that material 5 (such as a glass substrate) can seamlessly enter the electroplating tank 200 for subsequent processing.

[0061] The conveying device 2 is installed within the conveying channel 13 and can be a conveyor belt structure or a roller structure; no special limitation is made here. The conveying device 2 is used to carry and drive the material 5 from the first feed port 11 to the second feed port 12. The conveying device 2 is fixedly connected to the housing 1, and a water-blocking component is provided between it and the second feed port 12 to form a physical isolation. In this way, the conveying device 2 not only ensures that the material 5 moves smoothly during conveying, reducing the risk of breakage due to vibration or tilting, but also, in conjunction with the water-blocking component, prevents the electroplating solution from overflowing from the second feed port 12 to the outside of the conveying channel 13.

[0062] The water-blocking assembly includes a water-blocking plate or water-blocking roller 31, defining a passage gap 32 (such as a slit or channel) for the material 5 to pass through. The water-blocking assembly is fixed between the conveying device 2 and the second feed port 12, and communicates with the suction port 433 of the suction knife assembly based on the passage gap 32. The functions of the water-blocking assembly are as follows: it physically prevents the electroplating solution from overflowing from the second feed port 12 into the conveying channel 13, protecting the surface of the material 5 from contamination; at the same time, it provides a path for the electroplating solution to be recovered by the suction knife assembly using the passage gap 32, ensuring that the overflowing solution is absorbed in a timely manner.

[0063] The suction knife assembly includes a pump body 41, a suction pipe 42, and a suction knife body 43, which are connected in sequence. The suction knife body 43 is installed between the conveying device 2 and the second feed port 12, adjacent to the water-blocking component. One end of the suction pipe 42 is connected to the pump body 41, and the other end is connected to the suction port 433 of the suction knife body 43. The suction port 433 of the suction knife body 43 is directly connected to the through gap 32 of the water-blocking component. In this way, the pump body 41 drives the electroplating solution to flow along the suction pipe 42 through negative pressure, realizing liquid recovery; the suction pipe 42 serves as a transmission channel for the electroplating solution, connecting the pump body 41 and the suction knife body 43. It can be understood that the suction knife body 43, through the communication between the suction port 433 and the through gap 32, quickly absorbs the electroplating solution overflowing onto the surface of the material 5, preventing it from damaging the thin copper layer and other plating layers of the material 5.

[0064] Based on the above specific structure, the basic working principle of the conveying mechanism 100 of this utility model is as follows:

[0065] After the pump body 41 starts, a negative pressure environment is formed inside the suction knife body 43 through the suction pipe 42. Under the action of negative pressure, the electroplating liquid (such as overflow liquid) in the gap 32 of the water-blocking component is sucked into the suction port 433 of the suction knife body 43. The suction port 433 of the suction knife body 43 directly faces the gap 32 to ensure rapid absorption of the electroplating liquid overflowing onto the surface of the material 5. The suction pipe 42 transports the absorbed electroplating liquid to the pump body 41, and it can then be returned to the electroplating tank 200 or centrally treated to form a closed loop circulation.

[0066] Understandably, on the one hand, the installation position of the suction knife body 43 (adjacent to the water-blocking component) enables it to respond in real time to the overflow phenomenon when the material 5 passes through, without the need for manual intervention; on the other hand, the connection design between the suction port 433 and the passage gap 32 ensures that the suction knife component can cover the overflow area on the surface of the material 5, reducing the risk of residual liquid.

[0067] Furthermore, the specific working process of the conveying mechanism 100 of this utility model will be described below. It should be noted that the conveying mechanism 100 can be installed upstream or downstream of the electroplating tank 200. When the installation position of the conveying mechanism 100 is different, its specific working process will also be different. The specific working process of the conveying mechanism 100 installed in different positions will be described below.

[0068] When the conveying mechanism 100 is installed upstream of the electroplating tank 200, its operation is as follows: Material 5 (such as a glass substrate) enters the housing 1 through the first inlet 11 and moves along the conveying channel 13 to the second inlet 12 (adjacent to the inlet of the electroplating tank 200) under the drive of the conveying device 2. At this time, material 5 has not yet come into contact with the electroplating solution, but a small amount of liquid residue or overflow may occur due to pretreatment steps (such as cleaning or preheating). When material 5 approaches the second inlet 12, the through gap 32 of the water-blocking component allows material 5 to pass through, while the suction port 433 of the suction knife component is connected to the through gap 32. The pump body 41 starts, and a negative pressure is formed inside the suction knife body 43 through the liquid suction pipe 42 to absorb the residual or overflowing liquid (such as cleaning liquid or pretreatment liquid) and prevent it from entering the electroplating tank 200 and contaminating the electroplating solution. The suction knife component continues to operate, and after ensuring that there is no residual liquid on the surface of material 5, material 5 enters the electroplating tank 200 through the second inlet 12 to start the electroplating process.

[0069] It is understandable that when the conveying mechanism 100 is installed upstream of the electroplating tank 200, the suction knife assembly can be used for cleaning in the pretreatment stage. That is, the suction knife assembly removes residual liquid on the surface of the material 5 before it enters the electroplating tank 200 to avoid contaminating the electroplating solution and ensure the quality of electroplating. On the other hand, it can protect the environment of the electroplating tank 200. That is, the suction knife assembly reduces the accumulation of liquid in the inlet area of ​​the electroplating tank 200 by recovering the overflow liquid, thereby reducing the risk of contamination in subsequent processing steps.

[0070] When the conveying mechanism 100 is installed downstream of the electroplating tank 200, its working process is as follows: After the material 5 is taken out from the electroplating tank 200, it enters the conveying channel 13 through the second feed port 12 and moves downstream (such as a recovery liquid tank or a cleaning tank) under the drive of the conveying device 2. During the electroplating process, a large amount of electroplating liquid may drip onto the surface of the material 5, and some liquid may overflow along the edge of the material 5 into the conveying channel 13. When the material 5 passes through the through gap 32 of the water-blocking component, the suction port 433 of the suction knife component faces the through gap 32 directly, and the pump body 41 forms a negative pressure through the suction pipe 42 to quickly absorb the overflowing electroplating liquid. The absorbed liquid is transported to the pump body 41 through the suction pipe 42 and returned to the electroplating tank 200 or a centralized treatment system as needed to realize the recycling of electroplating liquid. The suction knife component continues to operate, and after ensuring that there is no excess electroplating liquid on the surface of the material 5, the material 5 enters the next treatment tank (such as a recovery liquid tank or a cleaning tank) through the second feed port 12 to complete the subsequent process steps.

[0071] It is understandable that when the conveying mechanism 100 is installed downstream of the electroplating tank 200, the suction knife assembly can achieve the effect of preventing pollution after electroplating. That is, the suction knife assembly immediately recovers the dripping electroplating liquid after the material 5 leaves the electroplating tank 200 to prevent it from contaminating subsequent processing steps (such as cleaning tank or recovery liquid tank). On the other hand, it can realize the recovery and circulation of electroplating liquid. That is, the suction knife assembly reduces the waste of electroplating liquid by efficiently recovering the overflow liquid, while avoiding liquid dripping onto the ground or inside the equipment, ensuring the safety of the production environment.

[0072] As described above, when installed upstream, the core function of the suction knife assembly is cleaning during the pretreatment stage, ensuring that there is no residual liquid before material 5 enters the electroplating tank 200, thus protecting the purity of the electroplating solution. When installed downstream, the core function of the suction knife assembly is post-electroplating contamination prevention and electroplating solution recovery, reducing the risk of contamination in subsequent processes and achieving resource recycling. Both installation methods improve the stability and environmental friendliness of the electroplating process through the dynamic recovery mechanism of the suction knife assembly.

[0073] In summary, the conveying mechanism 100 of the electroplating equipment according to this embodiment of the present invention, by introducing a suction knife assembly and its dynamic communication design with the passage gap 32, solves the defects of the existing electroplating equipment conveying mechanism 100 in terms of overflow recovery, material 5 contamination control, and maintenance costs. Specific advantages are as follows:

[0074] (1) The suction knife assembly of this utility model drives the liquid suction pipe 42 through the pump body 41, forming a negative pressure in the suction knife body 43, and directly recovers the overflow liquid through the water suction port 433 and the gap 32. This design can dynamically adapt to the liquid dripping generated during the movement of material 5, avoid liquid contamination of the surface of material 5, and significantly reduce the risk of uneven coating or corrosion.

[0075] (2) The suction knife assembly of this utility model recovers the overflow liquid immediately when the material 5 passes through the gap 32, ensuring that the surface of the material 5 is clean. It is especially suitable for materials 5 such as glass substrates or thin circuit boards that are sensitive to surface quality.

[0076] (3) The suction knife assembly of the utility model uses a negative pressure recovery mechanism to concentrate the overflow liquid to the pump body 41 and return it to the electroplating tank 200 or the treatment system, which greatly reduces the situation of liquid dripping into the equipment, extends the service life of the equipment and reduces the need for manual intervention.

[0077] (4) The suction knife body 43 of this utility model is installed between the conveying device 2 and the second material port 12 and adjacent to the water blocking component. Its suction port 433 directly faces the passage gap 32, which can respond to the movement trajectory of the material 5 in real time, efficiently recover the overflow liquid, and avoid liquid residue or diffusion.

[0078] like Figure 5 and Figure 6 As shown, according to some embodiments of the present invention, the water-blocking assembly includes at least two sets of water-blocking rollers 31. The two water-blocking rollers 31 in the same set are arranged opposite each other and define a passage gap 32. The water-blocking rollers 31 in different sets are arranged at intervals along the material conveying direction 5, and an installation gap 33 that communicates with the passage gap 32 is defined between every two sets of adjacent water-blocking rollers 31.

[0079] The suction knife body 43 extends into the installation gap 33 and communicates with the passage gap 32 through the suction port 433.

[0080] In this embodiment, the water-blocking roller group 31 consists of at least two groups of water-blocking rollers 31, each group including two oppositely arranged rollers forming a passage gap 32 (i.e., a channel through which the material 5 passes). Different groups of water-blocking rollers 31 are arranged at intervals along the material 5 conveying direction, and adjacent groups form an installation gap 33 (i.e., an area not covered by the water-blocking rollers 31). The suction knife body 43 is embedded in the installation gap 33 between adjacent groups of water-blocking rollers 31, and its suction port 433 directly faces the installation gap 33 and is connected to the passage gap 32 through structural design.

[0081] Its working principle is as follows: The water-blocking rollers 31 form a passage gap 32 through the relatively arranged roller bodies. The material 5 passes through each gap sequentially along the conveying direction, while the overflow and diffusion of the electroplating solution or pretreatment solution are blocked by the water-blocking rollers 31. When liquid overflows from the passage gap 32 due to the movement of the material 5, it flows into the installation gap 33 between adjacent water-blocking rollers 31. The suction knife body 43 is embedded in the installation gap 33, and its suction port 433 draws the overflow liquid into the suction knife body 43 through negative pressure, and then transmits it to the pump body 41 through the suction pipe 42, realizing liquid recovery.

[0082] It is understandable that the spaced arrangement of the water-blocking rollers 31 can ensure that the installation gap 33 always exists, and the suction knife assembly can recover the overflow liquid at different locations, covering the liquid droplets in the movement trajectory of the material 5 without adjusting the position.

[0083] In this way, the combination of the through gap 32 and the installation gap 33 of the water-blocking roller group 31 ensures the smooth conveying of material 5 and provides a directional recovery path for the overflow liquid, preventing the liquid from spreading to other areas of the conveying channel 13. Furthermore, the suction knife body 43 is directly embedded in the installation gap 33, and the suction port 433 is connected to the through gap 32, which can recover the overflow liquid in real time, preventing the liquid from contaminating the surface of material 5 or entering subsequent processes.

[0084] like Figure 8 As shown, according to some embodiments of the present invention, the suction knife body 43 includes a suction knife seat 431 and a plurality of suction knife blades 432. The suction knife seat 431 is connected to the liquid suction pipe 42. The suction knife blades 432 protrude from the surface of the suction knife seat 431 and extend into the installation gap 33, with one end of the suction knife 432 adjacent to the end passing through the gap 32 forming a water suction port 433.

[0085] In this embodiment, the suction knife seat 431 is the main body of the suction knife body 43, connected to the liquid suction pipe 42, and responsible for transferring the liquid collected at the suction port 433 to the pump body 41. Several suction knife blades 432 protrude from the surface of the suction knife seat 431 and are embedded in the installation gap 33 between adjacent sets of water-blocking rollers 31. The end of each suction knife blade 432 (i.e., the end adjacent to the gap 32) forms a suction port 433.

[0086] The suction blade 432 extends from the surface of the suction base 431 into the installation gap 33, with its suction port 433 directly facing the passage gap 32, ensuring efficient recovery of overflow liquid. Simultaneously, multiple suction blades 432 are distributed along multiple installation gaps 33, with one suction blade 432 installed in each installation gap 33, thereby covering a wider overflow area and improving the comprehensiveness and efficiency of liquid recovery.

[0087] The specific working process of the suction knife body 43 is as follows: When the electroplating solution or pretreatment solution overflows from the passage gap 32 due to the movement of material 5, the liquid flows into the installation gap 33 between adjacent sets of water-blocking rollers 31. The suction knife blade 432 is embedded in the installation gap 33, and its suction port 433 draws the overflow liquid into the suction knife body 43 through negative pressure, and then transmits it to the pump body 41 through the suction pipe 42. The suction knife seat 431 provides a stable negative pressure environment through the suction pipe 42, driving the suction port 433 of the suction knife blade 432 to continuously recover the liquid; the protruding design of the suction knife blade 432 allows it to penetrate deep into the installation gap 33, directly contact the overflow liquid, and prevent the liquid from spreading to other areas.

[0088] In summary, the embedded layout and multi-blade design of the suction blade 432 significantly improves liquid recovery efficiency and reduces the risk of overflow liquid contaminating the surface of material 5. Simultaneously, the protruding structure of the suction blade 432 directly contacts the overflow liquid, preventing increased equipment operating resistance due to liquid accumulation and ensuring the stable operation of the conveying device 2.

[0089] like Figure 3 , Figure 9 and Figure 10 As shown, in some specific embodiments of this utility model, a groove 434 is formed on the side surface of the suction knife seat 431 facing the water-blocking roller 31. The shape of the groove 434 matches the shape of the water-blocking roller 31, and the water-blocking roller 31 is fitted into the groove 434 with a clearance.

[0090] In this embodiment, the suction knife holder 431 has a groove 434 on the side facing the water-blocking roller 31. The shape of the groove 434 matches the outer contour of the water-blocking roller 31, thereby ensuring that the water-blocking roller 31 is stably fitted in the groove 434, while allowing its position to be finely adjusted axially or radially. For example, if the water-blocking roller 31 is cylindrical, then the groove 434 is arc-shaped. The water-blocking roller 31 is fitted into the groove 434 through a gap 32, that is, a certain gap is reserved between the two, which facilitates the smooth rotation of the water-blocking roller 31, and can also adapt to the small displacement caused by thermal expansion or vibration during operation.

[0091] The groove 434 ensures the positioning and installation of the suction knife body 43, while the clearance fit avoids affecting the normal rotation of the water-blocking roller 31, thus ensuring the installation stability and positioning accuracy of the suction knife body 43 while ensuring its basic functions.

[0092] It is understandable that the water-blocking roller 31 maintains a certain degree of freedom within the groove 434 through the gap 32, allowing it to rotate as the material 5 moves, thereby effectively guiding the material 5 through the gap 32 and preventing conveying interruptions or damage to the material 5 due to jamming. Simultaneously, the gap fit between the groove 434 and the water-blocking roller 31 allows for flexible fitting within dimensional tolerances, avoiding friction or jamming problems caused by machining accuracy deviations or assembly stress.

[0093] In summary, this invention achieves the dual goals of precise installation of the suction knife body 43 and free rotation of the water-blocking roller 31 through the coordinated design of the groove 434 and the clearance fit. On the one hand, the groove 434 ensures the positioning stability of the suction knife body 43 within the conveying channel 13, preventing liquid recovery failure due to installation deviation; on the other hand, the clearance fit eliminates frictional resistance during the rotation of the water-blocking roller 31 by reserving controllable space, while ensuring its functional integrity.

[0094] like Figures 3 to 5As shown, in some specific embodiments of this utility model, the suction blade body 432 is fitted within the installation gap 33 and spans the entire installation gap 33. Both the suction blade body 432 and the suction port 433 extend along the length direction of the installation gap 33, and the width of the suction port 433 is smaller than the width of the suction blade body 432.

[0095] In this embodiment, the suction blade 432 extends along the length direction (material 5 conveying direction) of the mounting gap 33 and spans the entire mounting gap 33, with its width consistent with the mounting gap 33. The suction blade 432 can provide structural support through its wide coverage, ensuring the stability of the suction blade body 43 within the mounting gap 33, while its edge portion forms a physical isolation with the water-blocking roller 31, reducing liquid diffusion.

[0096] It should be noted that the suction blade body 432 and the installation gap 33 are fitted together through a gap 32, meaning that the width of the suction blade body 432 is slightly smaller than the installation gap 33, leaving a controllable gap. In this way, on the one hand, the gap fit allows the suction blade body 432 to adapt to the rotational movement of the baffle roller 31 during material 5 conveying, maintaining the communication between the suction port 433 and the gap 32, while avoiding mechanical interference caused by fixed installation; on the other hand, the reserved gap can compensate for manufacturing errors, assembly deviations, or thermal expansion during operation, ensuring that the suction blade body 432 can freely adjust its position within the installation gap 33, avoiding jamming caused by forced fixing.

[0097] The suction port 433 also extends along the length of the installation gap 33, but its width is smaller than that of the suction blade body 432, covering only a portion of the installation gap 33 (such as the critical overflow area adjacent to the gap 32). In this way, the suction port 433 can accurately collect liquid from the area where the overflow is most concentrated, avoiding suction dispersion or mechanical interference caused by a wide suction port 433.

[0098] It is understandable that the combination of the wide coverage of the suction blade 432 and the narrow design of the suction port 433 ensures both structural stability and optimizes liquid recovery efficiency. Specifically, the wide coverage of the suction blade 432 provides stable support for the suction port 433, preventing it from shifting due to vibration or load changes; the narrow design of the suction port 433 targets the area in the installation gap 33 where liquid overflow is most significant (such as the local area adjacent to the gap 32), achieving efficient recovery through concentrated suction.

[0099] In summary, this utility model achieves synergistic optimization of structural stability and liquid recovery efficiency through the differentiated width design of the suction blade 432 and the suction port 433, combined with the dynamic adaptability of the clearance fit. Specifically, the wide coverage of the suction blade 432 can provide structural support and liquid guidance functions, ensuring the stability of equipment operation; the narrow design of the suction port 433 can accurately recover liquid in key overflow areas, improving liquid recovery efficiency and reducing the risk of mechanical interference.

[0100] like Figures 8 to 11 As shown, the suction knife seat 431 extends along the length of the installation gap 33. The side surface of the suction knife seat 431 facing away from the water-blocking roller 31 is provided with several sets of water outlet interfaces 435 connected to the liquid suction pipe 42. Each set of water outlet interfaces 435 includes multiple water outlet interfaces 435 connected to the same water suction port 433. The multiple water outlet interfaces 435 in the same set are arranged at intervals along the length of the installation gap 33.

[0101] In this embodiment, the suction knife holder 431 extends along the length direction of the mounting gap 33 (the material conveying direction 5), forming a long strip structure parallel to the mounting gap 33. On the one hand, the suction knife holder 431 can provide continuous support for the suction knife blade 432 and the suction port 433, ensuring their stable embedding along the length direction of the mounting gap 33; on the other hand, the extended design enhances the structural strength of the suction knife body 43, avoiding deformation or breakage caused by localized stress.

[0102] The suction knife holder 431 has several sets of water outlet ports 435 on the side facing away from the water-blocking roller 31. Each set of water outlet ports 435 corresponds to a water suction port 433, ensuring that the liquid collected by the water suction port 433 can be discharged through multiple paths, avoiding the problem of liquid accumulation caused by blockage of a single port. Each set of water outlet ports 435 includes multiple independent ports, and the water outlet ports 435 in the same set are distributed at intervals along the length direction, which can disperse the liquid flow velocity and pressure, and reduce the risk of pipe wear or blockage caused by excessive local flow.

[0103] It is understood that after collecting overflow liquid, each suction port 433 transports the liquid to the corresponding set of outlet ports 435 through the internal channel of the suction knife body 43. Multiple ports in each set of outlet ports 435 are spaced apart along the length, allowing the liquid to exit through multiple paths, preventing single ports from failing due to high flow rates. The spaced arrangement of multiple outlet ports 435 helps to balance liquid pressure, preventing pipe leaks or blockages caused by excessive local pressure. The dispersed outlet paths also reduce the flow load on individual ports, extending the service life of the suction pipe 42 and the pump body 41.

[0104] Thus, the above embodiment achieves high efficiency, reliability, and adaptability of the liquid recovery system through the extended design of the suction base 431 and the grouping and spacing of the water outlet 435. Specifically, the extension of the suction base 431 ensures that the suction port 433 and the water outlet 435 cover the entire installation gap 33, thereby improving the comprehensiveness of liquid recovery; while the grouping and spacing of the water outlet 435 disperses liquid pressure, balances flow, reduces the risk of clogging, and thus extends equipment life.

[0105] like Figures 3 to 6 As shown, according to some embodiments of the present invention, the conveying device 2 includes a plurality of conveying rollers 21 arranged at intervals along the transport direction of the material 5. Each conveying roller 21 is provided with a first roller 22, a third roller 23 and a second roller 24 in sequence along its length direction. The first roller 22, the second roller 24 and the third roller 23 are respectively used to contact the ineffective area of ​​the glass substrate and support the glass substrate.

[0106] In this embodiment, multiple conveying rollers 21 are arranged at intervals along the material transport direction 5 to form a continuous conveying path. Each conveying roller 21 has three rollers arranged sequentially along its length, namely the first roller 22, the third roller 23, and the second roller 24. The three rollers support the ineffective areas of the glass substrate in sections, forming a multi-point support system. In this way, the arrangement of the three rollers can distribute the weight of the glass substrate, reduce single-point pressure, avoid glass breakage caused by local stress concentration, and thus ensure that the glass substrate remains stable during transportation.

[0107] It should be noted that the first roller 22, the second roller 24, and the third roller 23 all contact the ineffective areas (such as edges or non-functional areas) of the glass substrate, avoiding direct contact with the effective areas (such as coating areas) to prevent contamination or scratches on critical surfaces. Ineffective areas typically refer to glass edges or non-functional areas, and the roller design must ensure smooth contact surfaces and prevent the shedding of abrasive particles.

[0108] For example, during transport, the ineffective areas (such as the two side edges) of the glass substrate come into contact with the three rollers of the adjacent conveyor rollers 21. The rollers rotate, moving the glass substrate along the transport direction while providing uniform support to prevent the glass from sagging or tilting due to gravity. The first roller 22 and the second roller 24 are located in the ineffective areas at both ends of the glass substrate, providing end support to prevent edge warping. The third roller 23 is located in the middle ineffective area, providing central support, balancing the center of gravity of the glass substrate, and reducing vibration or twisting.

[0109] In summary, this invention solves the stability problem of traditional single-point or double-point support systems during glass substrate transportation by employing a three-roller segmented support and ineffective area contact strategy. The multi-point support structure disperses weight pressure, preventing glass breakage; while the roller-contact-ineffective-area support method protects the quality of the effective area, thereby reducing the risk of contamination. Furthermore, this invention can adapt to glass substrates of different sizes (such as varying aspect ratios) by adjusting the roller spacing, thus improving the equipment's versatility.

[0110] like Figure 6 As shown, the first roller 22 is provided with a first baffle 25 on the side away from the third roller 23, and the second roller 24 is provided with a second baffle 26 on the side away from the third roller 23.

[0111] In this way, the first baffle 25 and the second baffle 26 can restrict the lateral movement of the glass substrate during transportation, preventing it from deviating from the predetermined path. Simultaneously, the segmented support of the glass ineffective area by three rollers further enhances the stability and safety of the overall transportation process. Furthermore, the baffle structure is simple, easy to install and maintain, and suitable for conveying glass substrates of various sizes.

[0112] like Figure 6 As shown, the outer side of the first roller 22 is fitted with a first elastic washer 27, the outer side of the second roller 24 is fitted with a second elastic washer 28, and the outer side of the third roller 23 is fitted with a third elastic washer 29. These elastic washers are typically made of rubber, silicone, or other flexible materials and have a certain degree of elasticity and friction.

[0113] It is understandable that the elastic washer acts as a buffer between the roller and the glass substrate, reducing the risk of impact or scratches from rigid contact. At the same time, the surface of the elastic washer has a certain coefficient of friction, which can increase the friction between the roller and the ineffective area of ​​the glass, prevent slippage, and ensure smooth glass transportation.

[0114] Furthermore, because elastic washers have a certain degree of compressive deformation capability, they can be adapted to glass substrates of different thicknesses, improving the versatility of the equipment. Moreover, compared to metal rollers directly contacting the glass, the use of elastic washers significantly reduces operating noise, improving the quietness of the equipment's operation.

[0115] like Figures 1 to 11 As shown, the electroplating equipment according to the second aspect of the present invention includes a conveying mechanism 100 as described in the first aspect of the present invention, and also includes an electroplating tank 200.

[0116] like Figure 1As shown, there are two conveying mechanisms 100, which are located upstream and downstream of the electroplating tank 200 respectively and are connected to the electroplating tank 200 through the second material port 12.

[0117] According to the electroplating equipment of this utility model embodiment, the upstream conveying mechanism 100 is responsible for feeding the glass substrate to be electroplated into the electroplating tank 200, and the downstream conveying mechanism 100 is responsible for feeding the glass substrate that has been electroplated out of the electroplating tank 200. The above structure realizes fully automated continuous operation from feeding, electroplating to discharging.

[0118] It should be noted that the two conveying mechanisms 100 located on both sides of the electroplating tank 200 are connected to the electroplating tank 200 through the second feed port 12, and together with the suction knife assembly and the water-blocking roller 31, they achieve good liquid protection capabilities. Specifically, on the one hand, the above-mentioned structure effectively prevents the electroplating solution from overflowing both upstream and downstream of the electroplating tank 200, ensuring a clean workshop environment and operational safety; on the other hand, the upstream conveying mechanism 100 can clean the material 5 during the pretreatment stage through the suction knife assembly, ensuring that there is no residual liquid before the material 5 enters the electroplating tank 200, thus protecting the purity of the electroplating solution; while the downstream conveying mechanism 100 uses the suction knife assembly to achieve post-electroplating pollution prevention and electroplating solution recovery, reducing the pollution risk of subsequent processes and realizing resource recycling.

[0119] In summary, the electroplating equipment provided by this utility model achieves efficient, stable, and continuous conveying of glass substrates by employing two conveying mechanisms 100 located upstream and downstream of the electroplating tank 200 respectively, and connected to the electroplating tank 200 through the second material port 12, while also possessing good liquid protection capabilities and process compatibility.
