Description

Technical Field

[0001] The invention relates to the technical field of metal drying, in particular to a device for drying metal surfaces after electroplating. Background Art

[0002] In the electroplating process, drying after electroplating is an important step. The purpose of drying is to ensure the bonding strength between the electroplated layer and the base metal and to prevent the electroplated layer from being corroded or damaged due to moisture during subsequent processing or use. By drying, moisture on the surface of the electroplating layer can be removed to prevent moisture from becoming a corrosive medium, thereby protecting the integrity and durability of the electroplating layer. For example, a device for rapid drying of a metal surface after electroplating with publication number CN211120484U, through the coordinated use of a pressing plate, a connecting plate and an electric fan, manually push the two pressing plates between the two connecting plates in opposite directions until the metal plate to be dried can be placed between the two connecting plates. Under the action of the elastic potential energy of the spring, the two pressing plates move in opposite directions, so that the two pressing plates move to the metal plate, press the metal plate, rotate the turntable ninety degrees, fix and clamp another metal plate, clamp the metal plates in turn, and blow two electric fans in opposite directions, so that the heat dries the four metal plates.

DETAILED DESCRIPTION

[0035] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The present invention provides a post-electroplating drying device for metal surface by improvement. The technical solution of the present invention is:

[0037] A post-electroplating drying device for a metal surface comprises a dryer 5 and a bottom plate 14, wherein a plurality of bases 13, a support L plate 1 9 and a support L plate 2 12 are fixed on the top of the bottom plate 14, a side support column 10 and a bottom support column 40 are fixed between the support L plate 1 9 and the support L plate 2 12, a rotator 2 is provided on the top of one of the bases 13, a pulling mechanism is provided on the side support column 10 and the bottom support column 40, a front side plate 51 and a rear side plate 52 are respectively fixed on both sides of the dryer 5 by screws, an air outlet 4 is provided on the top of the dryer 5, and a variable The flow tube 27 has a plurality of flow-changing holes 270 formed on its outer peripheral wall, a sliding hole plate 25 is slidably connected inside the flow tube 27, a central movable shaft 17 is inserted into the rotator 2, a rotating hole plate 24 is fixed to one end of the central movable shaft 17 that passes through the interior of the flow tube 27, the sliding hole plate 25 is sleeved on the outer peripheral wall of the central movable shaft 17 and fits with the rotating hole plate 24, the sliding hole plate 25 has a plurality of flow holes 250 formed on it, and a plurality of flow holes 1 240 formed on the rotating hole plate 24, and the flow holes 250 and the flow holes 1 240 have the same shape and size.

[0038] The arrangement of the variable flow holes 270 should be clear that: a plurality of variable flow holes 270 are evenly distributed on the variable flow tube 27 in a circumferential manner, and the cross-sectional diameter of the variable flow holes 270 at one end close to the hot gas inlet pipe 20 is smaller than that at the other end, that is, the opening thereof expands in a streamlined manner to the other end. Fig.14 and Fig.15 The metal tube 3 has different cross-sectional diameters, and the corresponding optimal hot air straight blowing effect is different. By adjusting the position of the rotating orifice plate 24 and the sliding orifice plate 25 in the variable flow cylinder 27 when they are closed, that is, the diameter of the metal tube 3 is equal to the intercept in the variable flow hole 270, such as Fig.14 The optimal staggered position 100 shown in the figure makes the intensity and coverage of the hot air directly blowing the metal tube 3 reach the best. This position should be and maximize the flow effect of the hot air. Specifically, when the hot air initially enters the variable flow tube 27, a part of the hot air first passes through the position with a small cross-sectional diameter of the variable flow hole 270 and directly blows the surface of the metal tube 3 at the corresponding position, and the remaining part continues to flow along the contour of the variable flow tube 27 and flows out from the position with a large cross-sectional diameter of the variable flow hole 270, cooperating with the rotating metal tube 3 to carry out comprehensive drying.

[0039] Furthermore, the movable handle 16 can adjust the position of the central movable axis 17 in the variable flow cylinder 27, that is, the position of the rotating orifice plate 24 and the sliding orifice plate 25 in the variable flow cylinder 27. On this basis, by reducing the distance between the rotating orifice plate 24 and the sliding orifice plate 25 and the fixed orifice column 271 when they are closed, the flow rate of the hot air passing through the variable flow hole 270 can be changed, thereby improving the effect of drying and blowing metal, and enabling the device to be flexibly adjusted.

[0040] In the present application, the central tooth 22 is used to drive the central movable shaft 17 to rotate continuously, so that the rotating orifice plate 24 rotates relative to the sliding orifice plate 25, thereby realizing the staggered reciprocating closure and circulation effect of the flow hole 1 240 and the flow hole 2 250, which can improve the overall drying effect and targeted drying and blowing effect of the drying metal tube 3.

[0041] Specifically, the outer wall of the rotator 2 on the side away from the dryer 5 is rotatably connected to a contour gear ring 19, and the inner and outer walls of the contour gear ring 19 are both provided with tooth surfaces. The outer wall of the rotator 2 on the side away from the dryer 5 is provided with a plurality of rotating mechanisms. The outer wall of the central movable shaft 17 is sleeved with a central tooth 22, and the inner wall of the sleeve hole of the central tooth 22 is provided with an inner hole protrusion 220. The outer wall of the central movable shaft 17 is provided with a gear groove 170, and the inner hole protrusion 220 cooperates with the gear groove 170 to slide. The end of the central movable shaft 17 away from the rotating hole plate 24 is rotatably connected to a movable handle 16.

[0042] Further references Figure 2-Figure 6 As shown, when the hot blower 21 introduces hot air through the hot air inlet pipe 20 for drying, when the hot air enters the variable flow tube 27, it will enter each variable flow hole 270 to continuously dry each rotating metal tube 3 and flow out from the air outlet 4. In this process, each metal tube 3 is located at the air guide position of the corresponding variable flow hole 270, and is blown by the hot air flowing out of the variable flow hole 270, thereby achieving the drying method after electroplating.

[0043] Specifically, the rotating mechanism includes a rotating ring 37 and a transmission gear ring 18. The rotating ring 37 is movably inserted into the outer wall of one side of the rotator 2, and the transmission gear ring 18 is sleeved and fixed on the outside of the rotating ring 37. Each transmission gear ring 18 is meshed with the inner wall tooth surface of the contour gear ring 19. All the transmission gear rings 18 are meshed with the same central tooth 22. A plurality of pressure strips 38 are inserted into the inner wall of the rotating ring 37. A plurality of one-way blocking strips 381 are provided on the outer wall of one side of the pressure strip 38. A rubber strip 39 is fixed between the outer wall of the other side of the pressure strip 38 and the inner wall of the rotating ring 37 to clamp metal pipes 3 of different diameters.

[0044] The metal tube 3 enters the rotating ring 37, and each pressure strip 38 provides a sliding resistance to achieve the effect of driving the metal tube 3 to rotate, that is, the active tooth 36 drives each transmission gear ring 18 to rotate the rotating ring 37, and each pressure strip 38 drives the metal tube 3 to rotate. When the metal tube 3 slides relative to the rotating ring 37, the axial setting effect of the one-way resistance strip 381 can still drive it to rotate without being affected by sliding, thereby ensuring that the metal tube 3 can be driven to rotate when forced to slide.

[0045] As a further implementation of the above scheme, the pulling mechanism includes a reciprocating telescopic machine 11, a first pull plate 6, a second pull plate 7 and a fixed plate 8, the reciprocating telescopic machine 11 is fixed to the outer wall of one side of the support L plate 9, the first pull plate 6 and the second pull plate 7 are both slidably mounted on the side support column 10 and the bottom support column 40, the fixed plate 8 is fixedly mounted on the side support column 10 and the bottom support column 40, the output shaft of the reciprocating telescopic machine 11 is fixed with a transmission plate 41, the transmission plate 41 is fixed to the outer wall of one side of the first pull plate 6 by screws, the outer wall of the second pull plate 7 on the side away from the first pull plate 6 is rotatably connected with a flower block 30, the flower block 30 is provided with a plurality of flower grooves 29, a plurality of matching clamping mechanisms are provided between the first pull plate 6 and the second pull plate 7, the first pull plate 6, the second pull plate 7 and the fixed plate 8 are all provided with A plurality of through holes 45 are provided, and a plurality of movable grooves 33 and arc grooves 44 are provided on the first pull plate 6 and the second pull plate 7. The arc grooves 44 are provided between two adjacent through holes 45. A connecting hole column 42 is fixed between the first pull plate 6 and the second pull plate 7. A fixed support column 81 is fixed to the outer wall of the fixed plate 8 on one side close to the second pull plate 7. A screw groove column 28 is slidably sleeved on the outside of the fixed support column 81. A high stiffness coefficient spring 800 is provided between the screw groove column 28 and the fixed support column 81. The screw groove column 28 penetrates the connecting hole column 42 and the flower block 30 to the outer wall of the first pull plate 6 on the side away from the second pull plate 7. A threaded groove 280 is provided on the outer peripheral wall of the screw groove column 28. A protrusion is provided in the hole of the flower block 30 to match the threaded groove 280, so that the flower block 30 can rotate when it moves on the screw groove column 28.

[0046] Among them, when the flower block 30 is limited by the thread groove 280, when the flower block 30 drives each fan plate 31 to no longer move to clamp the metal tube 3, the reciprocating telescopic machine 11 drives the first pull plate 6 and the second pull plate 7 to move toward the fixed plate 8 in combination with the screwing action of the flower block 30 and the screw groove column 28. The compression effect of the high stiffness coefficient spring 800 is required to ensure that the clamping of the clip 43 reaches the tightest degree, that is, when the screwing action of the flower block 30 and the screw groove column 28 reaches the rotation limit, the flower block 30 and the screw groove column 28 form a whole. When they continue to be subjected to unidirectional thrust, the two will move at the same time, compressing the high stiffness coefficient spring 800, and the screw groove column 28 has obvious sliding relative to the fixed support column 81, and the sliding distance is the distance for stretching each metal tube 3.

[0047] Specifically, the mating clamping mechanism includes a fan plate 31, two clips 43 and a sliding column 34. The fan plate 31 is sleeved and fixed on the outside of the sliding column 34. The sliding column 34 is slidably connected to the inside of the movable groove 33 and the flower groove 29. The two clips 43 are in contact with the two side walls of the fan plate 31 respectively. The clip 43 is provided with a through arc-shaped through hole 430. The outer peripheral wall of the clip 43 is provided with a strip groove 431, and the strip groove 431 is connected to the arc-shaped through hole 430. Two sliding arc plates 32 are slidably connected in the arc groove 44, and a spring is provided between the two sliding arc plates 32. The sliding arc plate 32 is fixedly inserted with a sliding rod 47, and the sliding rod 47 slides in the arc-shaped through hole 430. A rolling ring 48 is rotatably sleeved on the outside of the sliding rod 47. The outer walls of both sides of the fan plate 31 are provided with mating strip grooves 310, and the rolling ring 48 rolls between the mating strip groove 310 and the strip groove 431 on the clip 43 in contact with it.

[0048] Reference Fig.11 and Fig.12 When the two clamps 43 clamp the metal tube 3, the rotation of the metal tube 3 can drive the clamps 43 to roll a short distance relative to the fan plate 31. The clamps 43 in contact with the metal tube 3 will rotate a short distance under the cooperation of the slide rod 47 and the arc-shaped through hole 430, but can still maintain the effect of clamping the metal tube 3.

[0049] Further references Figure 9-13 , the operating principle of the above-mentioned pulling mechanism is further explained: the metal tube 3 is clamped by the clamping pieces 43 on both sides of the through hole 45. The specific state is that the reciprocating telescopic machine 11 drives the transmission plate 41 to make the first pull plate 6 and the second pull plate 7 move close to the fixed plate 8 first, and the flower block 30 is driven by the threaded groove 280 to repeatedly cooperate with the movable groove 33 to drive each slide column 34 to retract inward to the maximum limit, thereby driving each fan plate 31 to retract inward, squeezing the clamping pieces 43 on both sides of the fan plate 31 to clamp the metal tube 3, at this time, the transmission plate 41 continues to drive the first pull plate 6 and the second pull plate 7 to move close to the fixed plate 8, and pulls all the metal tubes 3 to move, and then the reciprocating telescopic machine 11 drives the transmission plate 41 to make the first pull plate 6 and the second pull plate 7 move away from the fixed plate 8, and each component moves towards the trend of releasing the contact effect, and no longer pulls the metal tube 3, so as to achieve the effect of successively pulling the metal tube 3 in this reciprocating manner.

[0050] Specifically, a limiting groove 26 is provided on the inner circumferential wall of the variable flow cylinder 27, and a fixed hole column 271 is fixedly provided on the side of the variable flow cylinder 27 close to the pulling mechanism, and a hot air inlet pipe 20 is inserted into the fixed hole column 271. The outer circumferential wall of the sliding orifice plate 25 is integrally formed with a orifice plate protrusion 251, and the orifice plate protrusion 251 slides in the limiting groove 26.

[0051] Specifically, a hot blower 21 and a rotating motor 35 are fixed on the top of the base plate 14 respectively. The hot blower 21 is connected to the hot air inlet pipe 20. The output shaft of the rotating motor 35 is fixed with a driving tooth 36 through a coupling. The driving tooth 36 is meshed with the tooth surface of the outer peripheral wall of the contour gear ring 19. The outer wall of the rotator 2 is fixedly sleeved with a limiting cylinder 1. The limiting cylinder 1 is provided with a sliding groove 15, and the moving handle 16 is located inside the sliding groove 15 and slides.

[0052] The working principle and explanation of the above-mentioned implementation scheme are further provided: when the device is in use, the same number of metal tubes 3 as the rotating mechanism are inserted into the interior thereof and penetrate to the outside of the fixed plate 8, and the rotating motor 35, the reciprocating telescopic machine 11 and the hot blower 21 are started. When the device is in operation, the reciprocating telescopic machine 11 repeatedly drives and pulls the metal tube 3 and keeps the metal tube 3 rotating, so that the entire metal tube 3 can be subjected to the effect of straight drying in all directions, which greatly improves the drying effect of the device, and the internal drying method can be intervened by adjusting the movable handle 16, so that the metal tubes 3 of different diameters can be flexibly and thoroughly dried.
