Description

Technical Field

[0002] In modern integrated steel belt EVCP vertical continuous electroplating line units, the copper plating tank and the processing tanks before and after it are equipped with partitions, and there is a partition between the pickling tank and the return tank. The partitions have a gap in the middle that allows the PCB board to pass through. A water-blocking wheel device is installed at this gap to slow down the exchange rate of liquids in different tanks (the liquid exchange phenomenon cannot be completely isolated, but the rate of liquid exchange can be slowed down as much as possible). The transmission structure of the water-blocking wheel is usually a large-volume fixed frame, with each tank using a single small fixed frame. Each small fixed frame is equipped with bearings, drive shafts and chains. When the conveyor steel belt (clamp) moves, the pins on the steel belt engage the chain rollers and drive the entire transmission structure synchronously.

[0003] The existing water-baffle's transmission structure is large in size, and a fixed frame is also installed above the copper plating cylinder section, which will affect the device for picking up and placing the anode titanium basket in the copper plating cylinder section; at the same time, the fixed frame is large in size and heavy, requiring at least two people to assemble and operate; the fixed frame has many parts, and the processing and assembly are time-consuming, resulting in high labor costs.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0036] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] The transmission structure of a baffle wheel typically uses a large fixed frame, with each cylinder using a single small fixed frame. Each small fixed frame is equipped with bearings, a drive shaft, and a chain. When the conveyor belt (clamp) moves, the pins on the belt engage the chain rollers, synchronously driving the entire transmission structure. Existing baffle wheel transmission structures are bulky, and the fixed frame is also located above the copper plating cylinder section, which affects the device for loading and unloading the anode titanium basket in the copper plating cylinder section. Furthermore, the fixed frame is large and heavy, requiring at least two people to assemble and operate; the fixed frame has many components, making processing and assembly time-consuming and labor costs high.

[0040] To address the aforementioned problems, this embodiment provides a double-baffle waterwheel transmission mechanism, see reference. Figures 1-4The system includes a fixed frame 10, a drive shaft 20, a synchronizing element 30, and a water-blocking wheel 40. The fixed frame 10 is located above the cylinder body 1. The drive shaft 20 extends vertically and is rotatably mounted on the fixed frame 10. A drive gear 21 is provided at the bottom of the drive shaft 20. There are at least two drive shafts 20, and all drive shafts 20 are connected by the synchronizing element 30, which is located above the cylinder body 1. The water-blocking wheel 40 extends vertically and is rotatably mounted at the bottom of the cylinder body 1. The number of water-blocking wheels 40 is [missing information]. The number of drive shafts 20 is twice that of the original shaft. Two water-blocking wheels 40 are located around one drive shaft 20. Each water-blocking wheel 40 has a water-blocking gear 41 at its bottom. The two water-blocking gears 41 can mesh with each other. When the PCB board 2 moves, the water-blocking wheels 40 need to rotate synchronously. Otherwise, the hard drive will scratch the board surface. When making flexible boards, if they do not rotate synchronously, they cannot pass through the water-blocking wheels 40. The rotation of the drive gear 21 can drive the two water-blocking gears 41 to rotate, allowing the PCB board 2 to pass between the two water-blocking wheels 40. Multiple drive shafts 20 are located on the same fixed frame 10. Fixed frames 10 can be omitted on some cylinder bodies 1, reducing the number of fixed frames 10 and related accessories. This avoids affecting the loading and unloading of other devices on some cylinder bodies 1. The synchronizing element 30 is located on the top of the cylinder body 1, and the drive gear 21 and water-blocking gear 41 are located on the bottom of the cylinder body 1. The design is small in size and easy to install, saving labor and material costs and improving the convenience of electroplating the PCB board 2.

[0041] In this embodiment, to prevent the drive shaft 20 from affecting the conveying of the PCB board 2, a gap needs to be maintained between the drive shaft 20 and the baffle wheel 40. Therefore, the double baffle wheel transmission mechanism also includes a bridge gear 50. The bridge gear 50 is located at the bottom of the cylinder body 1 and meshes with both the drive gear 21 and one of the two baffle gears 41. The bridge gear 50 maintains the gap between the drive shaft 20 and the baffle wheel 40. In other embodiments, the diameter of the drive gear 21 or the baffle gear 41 can be set to be larger to maintain the gap between the drive shaft 20 and the baffle wheel 40. In other embodiments, a synchronous belt can be used to connect the drive gear 21 and the baffle gear 41 to maintain the gap between the drive shaft 20 and the baffle wheel 40. In other embodiments, the drive shaft 20 and the baffle wheel 40 can be arranged side by side so that the drive shaft 20 cannot interfere with the baffle wheel 40.

[0042] Furthermore, a partition 3 is provided inside the cylinder body 1. Multiple partitions 3 are located behind the water-blocking gear 41 along the direction of conveying the PCB board 2. All partitions 3 have corresponding notches, and the gap between the two water-blocking wheels 40 corresponds to the position of the notches, allowing the PCB board 2 to pass between the two water-blocking wheels 40 and then through the notches. Specifically, the partitions 3 inside the cylinder body 1 divide the cylinder body 1 into electroplating tanks with different functions. In the prior art, a fixing frame is also provided above the copper plating tank, which affects the device for picking up and placing the anode titanium basket in the copper plating tank. In this embodiment, the fixing frame 10 can be placed at the front section of the copper plating tank. The PCB board 2 enters the copper plating tank after passing through the two water-blocking wheels 40 and the partitions 3, eliminating the need for a fixing frame 10 above the copper plating tank.

[0043] Furthermore, the synchronizing element 30 is configured as a chain, and a synchronizing gear 22 is mounted on the drive shaft 20, located above the cylinder body 1. Specifically, a conveying assembly 60 is also provided inside the cylinder body 1. The conveying assembly 60 includes conveying wheels 61, a steel belt, steel belt pins, and clamps 62 (existing technology). There are two conveying wheels 61, synchronously connected by the steel belt. There are multiple clamps 62, spaced apart on the steel belt, used to clamp the PCB board 2. The steel belt has steel belt pins arranged horizontally, which can engage with the gaps in the chain to drive the chain to move when the steel belt moves, thereby driving all the synchronizing gears 22 to rotate. In other embodiments, the synchronizing element 30 can be configured as a synchronous belt or a non-flexible rope, eliminating the steel belt pins. A rotary motor can be installed above one of the drive shafts 20 to drive the synchronizing element 30 to move, thereby driving all the synchronizing gears 22 to rotate.

[0044] Further, the fixing frame 10 includes a first fixing member 11 and a first connecting member 12. The first fixing member 11 extends along the direction of conveying the PCB board 2, and the first connecting member 12 is disposed on the first fixing member 11 and corresponds one-to-one with the drive shaft 20. The first connecting member 12 includes a first connecting hole 121, and the drive shaft 20 is clearance-fitted with the first connecting hole 121. Specifically, the first connecting member 12 is configured as a "convex" shape, with both sides of the first connecting member 12 screwed to the first fixing member 11, and the protruding part in the middle is provided with the first connecting hole 121. In this embodiment, the first fixing member 11 is configured as a fixing rod. In other embodiments, the first fixing member 11 can be configured as a fixing plate.

[0045] Furthermore, to prevent the drive shaft 20 from shifting during rotation, the fixing frame 10 also includes a second connecting member 13. The second connecting member 13 is located below the first connecting member 12 and corresponds one-to-one with the first connecting member 12. The second connecting member 13 includes a second connecting hole 131, which is coaxial with the first connecting hole 121. The drive shaft 20 is clearance-fitted with the second connecting hole 131. The second connecting member 13 has the same structure as the first connecting member 12. In this embodiment, the fixing frame 10 also includes a second fixing member 14, which is located below the first fixing member 11 and extends along the direction of conveying the PCB board 2. The second connecting member 13 is located on the second fixing member 14. Specifically, the second fixing member 14 is configured as a fixing rod or a fixing plate. In other embodiments, the second connecting member 13 may also be located on the first fixing member 11.

[0046] Furthermore, in order to make the drive shaft 20 rotate more smoothly, the mounting bracket 10 also includes a bearing, which is located between the drive shaft 20 and the first connecting hole 121 and / or between the drive shaft 20 and the second connecting hole 131.

[0047] Furthermore, the fixing frame 10 also includes a support member 15, which is detachably mounted on the top of the cylinder body 1 and is used to support the first fixing member 11 and the second fixing member 14. Specifically, there are two sets of support members 15, each set of support members 15 including three vertical rods and one horizontal rod. The two vertical rods are respectively supported on both sides of the cylinder body 1, and the two ends of the horizontal rod are respectively connected to the two vertical rods. The first fixing member 11 is welded or screwed to the horizontal rod, and one end of the third vertical rod is connected to the horizontal rod in the vertical direction for welding or screwing to the second fixing member 14.

[0048] Furthermore, the mounting bracket 10 also includes a base plate 16, which is detachably mounted on the bottom of the cylinder body 1. There are multiple base plates 16, each corresponding to a drive shaft 20. The drive gear 21, the water-blocking gear 41, and the bridge gear 50 are all rotatably mounted on the base plate 16. Specifically, the drive shaft 20, the bridge gear 50, and the water-blocking wheel 40 can all be mounted on the base plate 16, and then the base plate 16 can be installed on the bottom of the cylinder body 1 for easy installation and operation.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
