Technical Field

[0001] This invention relates to the field of photochemical etching technology for metal electronic components, specifically a sponge roller dewatering device. Background Technology

[0002] In the photochemical etching process of metal electronic components, the raw materials, semi-finished products and finished products need to be cleaned in the three process steps of pretreatment, development and etching. After cleaning, the metal components need to be dried. Before drying, multiple water-absorbing sponge rollers are used to absorb water and then the components are dried. This can greatly improve the drying effect and efficiency.

[0003] A sponge absorbent roller is a multi-porous material with interconnected micropores, exhibiting excellent water absorption and corrosion resistance, making it an ideal tool for removing surface moisture.

[0004] Traditional methods of squeezing water from sponge rollers rely entirely on manual labor. The water-absorbing sponge roller is tilted at a certain angle through round holes in the plate, and water is squeezed out manually. This method suffers from poor operational stability, low efficiency, insufficient water extraction, and often results in damage to the sponge portion of the roller. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides a sponge roller dewatering device, which has a simple structure, stable operation, sufficient water extrusion, is not easily damaged by the dewatering sponge roller, and the extruded water can be collected and recycled in a centralized manner. Moreover, different sizes of flexible dewatering screens can be flexibly replaced according to the diameter of the water-absorbing sponge roller.

[0006] To achieve the above objectives, the present invention provides a sponge roller dewatering device, which includes a trough and a sponge roller dewatering mechanism. The sponge roller dewatering mechanism includes one or more dewatering components. Each dewatering component includes a fixed shaft connected to the trough, a driving member disposed in the trough, a moving shaft connected to the moving end of the driving member, and a dewatering flexible net. One side of the dewatering flexible net is connected to the fixed shaft, and the other side of the dewatering flexible net is connected to the moving shaft, so that the dewatering flexible net is rolled up and a receiving cavity for accommodating the sponge roller is formed on the inner side of the dewatering flexible net. The driving member can drive the moving shaft to move closer to or away from the fixed shaft to expand or contract the receiving cavity.

[0007] Furthermore, the flexible dewatering net has a first connecting side and a second connecting side that are far apart from each other, and a covering area is provided between the first connecting side and the second connecting side, wherein the covering area has overflow mesh holes.

[0008] Furthermore, the overflow mesh can be elongated, circular, quadrilateral, polygonal, elliptical, or irregular in shape.

[0009] Furthermore, the length L1 of the covered area, in mm, is...

[0010] ;

[0011] in, The porosity of the absorbent sponge is expressed as %; the outer radius R1 of the sponge section of the sponge roller is expressed as mm; the inner radius R2 of the sponge section of the sponge roller is expressed as mm.

[0012] Furthermore, given that the width L2 of the covering area and the length L3 of the sponge portion of the sponge roller are equal, then L2 > L3.

[0013] Furthermore, the first connecting side includes a plurality of first protrusions, and the ends of the first protrusions are provided with first convex end rings; the second connecting side includes a plurality of second protrusions, and the ends of the second protrusions are provided with second convex end rings; the water-squeezing flexible net is rolled up, the first protrusions and the second protrusions are misaligned and intersecting, the first convex end rings are sleeved on the fixed shaft, and the second convex end rings are sleeved on the moving shaft.

[0014] Furthermore, when the number of the dewatering components is greater than one set, the dewatering components are arranged in parallel to each other.

[0015] Furthermore, the driving component is a cylinder, and the push-pull rod of the cylinder is connected to the moving shaft via a connecting rod.

[0016] Furthermore, a base is fixed to the bottom of the tank, and a drain pipe is provided in the tank.

[0017] Furthermore, the side of the trough is provided with inlet and outlet ports, which are used to provide channels for the sponge roller to enter and exit the accommodating cavity.

[0018] The beneficial effects of this invention are as follows: the sponge roller is placed in the teardrop-shaped receiving cavity formed by the rolled-up flexible mesh, and the piston rod of the driving component drives the moving shaft to move, thereby pushing the flexible mesh to one side to move, causing the flexible mesh to shrink and squeeze out the water in the sponge roller, resulting in a high water squeezing rate; this invention has a simple structure, uses the shrinkage of the flexible mesh for wrapping and squeezing, the sponge roller is not easily damaged, and the squeezed water can be centrally processed and quickly collected.

[0039] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] See Figure 1 , Figure 7 and Figure 8 This diagram illustrates a structural schematic of a sponge roller dewatering device according to an embodiment of the present invention. It is used to dewater the sponge portion 11 on a sponge roller 10. In this embodiment, the sponge roller 10 is a water-absorbing sponge roller for etching metal electronic components. The sponge roller dewatering device in this embodiment includes a base 100, a trough 200, and a sponge roller dewatering mechanism 300. The trough 200 is provided on the upper part of the base 100, and the sponge roller dewatering mechanism 300 is installed inside the trough 200.

[0041] See also Figure 1 and Figure 2 The sponge roller dewatering mechanism 300 includes one or more dewatering components 310. When the number of dewatering components 310 is greater than one, the dewatering components 310 are arranged in parallel with each other. In this embodiment, as an example, three sets of dewatering components 310 are provided. In other embodiments, one, two, three...N sets of dewatering components 310 can be provided, and the specific number can be set as needed. See also... Figure 2The dewatering assembly 310 includes a fixed shaft 311 connected to the tank 200, a drive member 312 disposed in the tank 200, a movable shaft 313 connected to the movable end of the drive member 312, and a dewatering flexible net 314. One side of the dewatering flexible net 314 is connected to the fixed shaft 311, and the other side of the dewatering flexible net 314 is connected to the movable shaft 313, so that the dewatering flexible net 314 is rolled up and a receiving cavity 20 for accommodating the sponge roller 10 is formed on the inner side of the dewatering flexible net 314. The drive member 312 is connected to the movable shaft 313 through a push-pull rod 3121 and a connecting rod 3122. The drive member 312 can drive the movable shaft 313 to move closer to or away from the fixed shaft 311 to expand or contract the receiving cavity 20. In this embodiment, the cross-section of the receiving cavity 20 is teardrop-shaped.

[0042] The aforementioned sponge roller dewatering device places the sponge roller 10 within the teardrop-shaped receiving cavity 20 formed by the rolled-up flexible dewatering net 314. The piston rod of the driving member 312 drives the moving shaft 313 to move, thereby pushing one side of the flexible dewatering net 314 to the right. This causes the flexible dewatering net 314 to contract and squeeze out the water from the sponge roller 10, resulting in a high water extraction rate. This invention features a simple structure, utilizes the contraction of the flexible dewatering net 314 for encapsulation-style dewatering, minimizes the risk of damage to the sponge roller 10, and allows for centralized and rapid collection of the squeezed-out water. Furthermore, the flexible dewatering net 314 can be flexibly replaced according to changes in the diameter of the sponge roller 10, making the device more widely applicable.

[0043] Specifically, see Figure 3 and Figure 4 In one embodiment, the flexible dewatering net 314 has a first connecting side 3141 and a second connecting side 3142 that are far apart from each other. A covering area 3143 is provided between the first connecting side 3141 and the second connecting side 3142, and the covering area 3143 has overflow mesh holes 3144. The overflow mesh holes 3144 are, but are not limited to, being elongated, circular, quadrilateral, polygonal, elliptical, or irregularly shaped. Figure 3 The diagram illustrates a circular overflow mesh 3144 arrayed in the covering area 3143. When the overflow mesh 3144 is polygonal, all inner corners are rounded to avoid damaging the sponge roller 10. The material of the flexible mesh 314 is stainless steel, polypropylene (PP), polyethylene (PE), high-density polyethylene (HDPE), or polyvinyl chloride (PVC), etc.

[0044] See also Figure 5 and Figure 7 In one embodiment, the length L1 of the covering region 3143 is in mm, and the formula for calculating the length of the covering region 3143 is as follows:

[0045] ;

[0046] in, The porosity of the absorbent sponge is expressed as %; the outer radius R1 of the sponge portion 11 of the sponge roller 10 is expressed as mm; the inner radius R2 of the sponge portion of the sponge roller 10 is expressed as mm.

[0047] Furthermore, in conjunction with see Figure 5 and Figure 7 In one embodiment, the width L2 of the covering area 3143 and the length L3 of the sponge portion 11 of the sponge roller 10 are equal, meaning L2 > L3. This indicates that the width of the covering area 3143 of the flexible dewatering net 314 should be greater than the length of the sponge portion 11 of the sponge roller 10. This ensures that the flexible dewatering net 314 can dewater the entire area of ​​the sponge portion 11 of the sponge roller 10, avoiding blind spots that could affect the dewatering effect. In practical applications, the width of the covering area 3143 should be 5mm-30mm greater than the length of the sponge portion 11 of the sponge roller 10.

[0048] See also Figure 3 and Figure 4 In one embodiment, the first connecting side 3141 includes a plurality of first protrusions 3145, and the ends of the first protrusions 3145 are provided with first convex end rings 3146; the second connecting side 3142 includes a plurality of second protrusions 3147, and the ends of the second protrusions 3147 are provided with second convex end rings 3148. Figure 2 As shown, in this embodiment, when the flexible dewatering net 314 is rolled into a teardrop shape, the first protrusion 3145 and the second protrusion 3147 are misaligned and intersected, the first convex end ring 3146 is sleeved on the fixed shaft 311, and the second convex end ring 3148 is sleeved on the movable shaft 313.

[0049] For specific settings, please refer to Figure 3 and Figure 6 The number of first protrusions 3145 can be 1, 2, 3...N, and the number of second protrusions 3147 corresponds to the number of first protrusions 3145, and can be 2, 3...N+1. See also Figure 6 This illustrates another embodiment where two first protrusions 3145 and three second protrusions 3147 are provided. Specifically, the number of protrusions can be selected and set according to the length L3 of the sponge portion 11 of the sponge roller 10. When connecting, it is sufficient to ensure that the ring on one side of the protrusion is connected to the fixed shaft 311 and the ring on the other side of the protrusion is connected to the movable shaft 313.

[0050] Specifically, see Figure 2 and Figure 3When the number of first protrusions 3145 is odd, the fixed shaft 311 passes through the first convex end ring 3146. Specifically, the pressure plate 225 is detachably connected to the fixed shaft support 226 to mount the fixed shaft 311 onto the groove 200. The movable shaft 313 passes through the second convex end ring 3148 and is connected to the push-pull rod 3121 via the connecting rod 3122. See comparison for further details. Figure 6 When the number of first protrusions 3145 is even, the fixed shaft 311 passes through the second convex end ring 3148. Similarly, the pressure plate 225 is detachably connected to the fixed shaft support 226 to install the fixed shaft 311 on the groove 200. The movable shaft 313 passes through the first convex end ring 3146 and is connected to the push-pull rod 3121 via the connecting rod 3122.

[0051] Furthermore, such as Figure 10 As shown, a circular bushing 320 is installed between the fixed shaft 311 and the movable shaft 313 and the circular ring. The circular bushing 320 is made of materials such as polyvinylidene fluoride (PVDF), POM (polyoxymethylene), PE (polyethylene), PP (polypropylene), PEEK (polyetheretherketone), PA66 (nylon), PTFE (polytetrafluoroethylene), etc.

[0052] To avoid interference between the first protrusion 3145 and the second protrusion 3147, the width of the first protrusion 3145 is smaller than the distance between the two second protrusions 3147 on the opposite side, with a size between 0.1mm and 2mm, so that the first protrusion 3145 can cross and fit between the two adjacent second protrusions 3147, and the mutual displacement is smoother.

[0053] In this embodiment, as Figure 1 As shown, there are three sets of dewatering components 310 arranged in parallel. It should be noted that the number of dewatering components 310 can be set according to the number of sponge rollers 10 to be processed and the area of ​​the site.

[0054] See Figure 1 , Figures 9-12 In one embodiment, the driving component 312 is a cylinder, specifically a double-acting cylinder or a double-acting hydraulic cylinder. The cylinder is fixed on the U-shaped frame 220, which is inverted and fixed to the upper part of the tank 200. Specifically, the U-shaped frame 220 is fixed to the upper part of the tank 200 across its length, as shown below. Figure 12As shown, U-shaped frame 220 has U-shaped frame fixing holes 221 on both sides. The U-shaped frame 220 is inverted and fixed above the groove 200 using bolts. The upper part of the U-shaped frame 220 has cylinder fixing holes 222 and push-pull rod bracket fixing holes 223. The cylinder is fixed below the inverted U-shaped frame 220 using bolts, and a push-pull rod bracket 224 is fixed thereon with bolts. The push-pull rod bracket 224 provides relatively sliding support for the cylinder's push-pull rod 3121 to improve the movement stability of the push-pull rod 3121, thereby improving the working stability of the device. It should be noted that besides the fixing method in this embodiment, the cylinder can also be fixed in other ways, as long as the cylinder can drive the moving shaft 313 to move closer to or away from the fixed shaft 311.

[0055] See also Figure 13 A bushing 2241 is installed between the push-pull rod 3121 and the push-pull rod bracket 224. The bushing 2241 is made of materials such as polyvinylidene fluoride (PVDF), POM (polyoxymethylene), PE (polyethylene), PP (polypropylene), PEEK (polyetheretherketone), PA66 (nylon), and PTFE (polytetrafluoroethylene). The push-pull rod bracket 224 includes a push-pull rod bracket base 2242 and a push-pull rod bracket cover 2243 that is detachably fixed to the upper part of the push-pull rod bracket base 2242.

[0056] See Figure 10 and Figure 11 The cylinder's push-pull rod 3121 is connected to the moving shaft 313 via a connecting rod 3122. In this embodiment, three sets of moving shafts 313 are provided, each set of moving shafts 313 is connected to a connecting rod 3122, and the three connecting rods 3122 are equally spaced and connected to the cylinder's push-pull rod 3121. When the cylinder's push-pull rod 3121 is activated, it can simultaneously drive the three sets of moving shafts 313 to move synchronously, resulting in greater synchronization and efficiency.

[0057] See Figure 1 and Figure 9 A base 100 is fixed to the bottom of the tank 200. The base 100 includes a support platform 110, support legs 120, and support feet 130. The support legs 120 are fixed to the bottom of the support platform 110, and the support legs 120 are connected to the support feet 130. The support feet 130 can be height adjusted to ensure the device is level. Figure 10 As shown, a water storage tank 230 is provided inside the tank body 200. The water storage tank 230 is used to receive liquid squeezed out from inside the sponge part 11 of the sponge roller 10. A drain pipe 231 is provided in the water storage tank 230 to drain the liquid inside the water storage tank 230.

[0058] See also Figure 9In one embodiment, the side of the tank 200 is provided with an inlet / outlet 210, which provides a channel for the sponge roller 10 to enter and exit the receiving cavity 20. It should be noted that the shape of the inlet / outlet 210 is not limited. In this embodiment, the inlet / outlet 210 is square. The inlet / outlet 210 only needs to be able to accommodate the sponge roller 10 with the sponge portion 11 into the receiving cavity 20. After squeezing, the sponge roller 10 can also be removed through the inlet / outlet 210, making operation more convenient. In this configuration, the inlet / outlet 210 on the tank 200 can be on one side or on both sides, with the positions of the inlets / outlets 210 on both sides corresponding to each other.

[0059] The design steps of this invention include:

[0060] See Figure 8 Taking the outer radius R1 of the sponge portion 11 of the sponge roller 10 as 25mm, the inner radius R2 of the sponge portion 11 of the sponge roller 10 as 10mm, the porosity of the water-absorbing sponge as 60%, and the length L3 of the sponge portion 11 of the sponge roller 10 as 1200mm as an example, a 314 stainless steel flexible mesh with a thickness of 0.3mm is selected for dewatering. The specific steps are as follows:

[0061] Step S100: The dimensions of the covering area 3143 of the water-depleting flexible net 314 are determined using the following formula for calculating the length of the covering area 3143 of the water-depleting flexible net 314: Calculate the length of L1.

[0062] The width of the covering area 3143 of the flexible dewatering net 314 should be greater than the length of the sponge portion 11 of the sponge roller 10: L2>L3;

[0063] The width of the covering area 3143 of the water-squeezing flexible net 314 should be 5mm-30mm wider than the length of the sponge part 11 of the sponge roller 10.

[0064] in, The porosity of the absorbent sponge is expressed as %; the length L1 of the covering area 3143 of the squeeze-out flexible net 314 is expressed as mm; the width L2 of the covering area 3143 of the squeeze-out flexible net 314 is expressed as mm; the outer radius R1 of the sponge portion 11 of the sponge roller 10 is expressed as mm; the inner radius R2 of the sponge portion 11 of the sponge roller 10 is expressed as mm; and the length L3 of the sponge portion 11 of the sponge roller 10 is expressed as mm.

[0065] The calculated value is L1 = 127.9 mm.

[0066] The dimensions of the covering area 3143 of the water-squeezing flexible net 314 are determined to be: length × width × thickness = 127.9mm × 1220mm × 0.3mm.

[0067] Step S200: The water-soaked sponge roller 10 is placed into the receiving cavity 20 of the teardrop-shaped flexible squeezing net 314 through the feed inlet 210.

[0068] Step S300, as follows Figure 10 and Figure 11 As shown, the drive cylinder pushes the push-pull rod 3121 to drive the moving shaft 313 to tighten the water-squeezing flexible net 314, and squeezes out the water in the sponge part 11 through the overflow net hole 3144 when it reaches the designated position.

[0069] Step S300: The reverse drive cylinder pulls the push-pull rod 3121 to drive the moving shaft 313 to pull the squeezing flexible net 314 back to the starting position and remove the sponge roller 10.
