Description

Technical Field

[0001] The present application relates to the technical field of vertical electroplating equipment, and in particular to a floating frame assembly and vertical electroplating equipment. Background Art

[0002] During the PCB manufacturing process, copper plating is required on the substrate surface, typically performed using vertical continuous plating. A steel belt VCP (Vertical Continuous Plating) line is a vertical continuous plating production line that utilizes a clamp to hold and suspend the plate to be plated. A steel belt drive mechanism drives the clamp to move the plate vertically through a copper tank (electrolytic cell). The tank contains the reaction solution required for electroplating and is equipped with a spray device that sprays both sides of the plate, ensuring that the plate receives copper deposition evenly during the electroplating process.

[0003] In the related art, in order to ensure that the electroplating plate can move smoothly in the copper trough, guide bars extending along the moving direction of the electroplating plate are usually provided on both sides of the electroplating plate. However, on the one hand, the electroplating plate will be sprayed in the copper trough, causing the electroplating plate to easily shift under the action of the spray; on the other hand, in order to ensure that the electroplating plate can pass smoothly between the guide bars on both sides, the gap between the guide bars on both sides is usually set to be larger, so it is difficult for the guide bars to position the electroplating plate in the middle position between the guide bars on both sides. During the movement of the electroplating plate in the copper trough, the bottom of the electroplating plate is prone to get stuck on the guide bar, resulting in problems such as poor copper plating of the electroplating plate and product scrapping.

[0027] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0028] See also Figure 1 , Figure 1 The structure diagram of the floating frame assembly 100 in the related art is shown. In order to ensure that the electroplating plate can move smoothly in the copper tank, two sides of the electroplating plate are usually provided with a plurality of support members along the moving direction of the electroplating plate (such as Figure 1 The guide bars 11 extend in the direction of the arrow in the figure, and a transport channel 12 is formed between the guide bars 11 on both sides. However, on the one hand, the electroplated plate will be sprayed in the copper tank, causing the electroplated plate to easily shift under the action of the spray; on the other hand, in order to ensure that the electroplated plate can pass smoothly between the guide bars 11 on both sides, the gap D between the guide bars 11 on both sides is usually set to be large. Therefore, it is difficult for the guide bars 11 to position the electroplated plate in the middle position between the guide bars 11 on both sides. During the movement of the electroplated plate in the copper tank, the bottom of the electroplated plate is likely to be stuck on the guide bar 11, resulting in problems such as poor copper plating of the electroplated plate and product scrapping.

[0029] First, see Figures 2 to 4The present application provides a floating frame assembly 100, including a guide wheel 20 and two sets of guide assemblies 10, the guide assemblies 10 including guide bars 11, the two sets of guide bars 11 are arranged in parallel and spaced apart to form a transport channel 12 between the guide bars 11, and the transport channel 12 is used to allow the electroplating plate 200 to pass vertically (the direction of the electroplating plate 200 can be referred to Figure 3 The guide wheel 20 is at least rotatably arranged on the upper or lower side of the guide bar 11, and at least a portion of the guide wheel 20 extends into the transport channel 12. The rotation direction of the guide wheel 20 is the same as the movement direction of the electroplating plate 200. By arranging a portion of the guide wheel 20 to extend into the transport channel 12, the width of the transport channel 12 can be narrowed, so that the guide wheel 20 can provide a sliding guide for the electroplating plate 200 passing through, which helps to confine the electroplating plate 200 between the guide assemblies 10 on both sides so that the electroplating plate 200 is positioned in the center of the transport channel. On the one hand, it can prevent the electroplating plate 200 from being stuck in the guide bar 11 due to warping, or prevent the electroplating plate 200 from rubbing against the guide bar 11, thereby avoiding scratches on the electroplating plate 200. At the same time, it can also prevent the edge of the electroplating plate 200 from rubbing against the guide assembly 10, causing wear and scratches on the guide assembly 10, thereby improving the reliability and service life of the guide assembly 10. On the other hand, the guide wheel 20 can play a supporting role on the electroplating plate 200, so that the electroplating plate 200 can be sprayed (such as Figure 4 The dotted arrow direction shown in the figure can still be maintained in the center of the transport channel 12, thereby improving the copper coating on both sides of the electroplating plate 200 and improving the uniformity of the electroplating, thereby improving the electroplating effect of the electroplating plate 200.

[0030] In some embodiments, each group of guide assemblies 10 includes at least two parallel guide bars 11, the two guide bars 11 are spaced apart in the vertical direction, and the guide wheel 20 is arranged between any two guide bars 11. By providing multiple guide bars 11, it is possible to provide guidance and support for the passing of the electroplating plate 200 in the vertical direction, thereby improving the smooth movement of the electroplating plate 200 during the continuous electroplating process. By arranging the guide wheel 200 between the two guide bars 11, space can be saved in the vertical direction, making the structure of the floating frame assembly 100 more compact. For example, Figure 2 As shown, each group of guide components 10 is provided with multiple guide bars 11, and the multiple guide bars 11 are arranged in parallel and spaced apart. This can not only provide vertical guidance for the electroplating plate 200, but also avoid blocking the spray, ensuring that the surface of the electroplating plate 200 can be evenly electroplated through the gaps in the guide bars 11.

[0031] In some embodiments, the guide assembly 10 further includes a shaft 13, the ends of which are respectively disposed on two guide bars 11 of the same guide assembly 10, and the guide wheel 20 is rotatably disposed within the shaft 13. By disposing the ends of the shaft 13 on the two guide bars 11, the guide wheel 20 can be installed, and the rotation direction of the guide wheel 20 can be made the same as the movement direction of the electroplating plate 200, thereby achieving the guiding effect of the guide wheel 20 on the electroplating plate 200. Of course, in other examples, the guide wheel 20 can also be installed using a structure such as a bearing seat, and the bearing seat can be disposed on the guide bar 11, thereby mounting the guide wheel 20 on the guide bar 11.

[0032] In some embodiments, the guide bar 11 is provided with a clearance hole 111, through which the shaft 13 is inserted. On the one hand, the clearance hole 111 itself can be used to install a spray pipe or a spray head in the copper tank, allowing the spray head to contact the surface of the electroplated plate to spray the plate. On the other hand, using the clearance hole 111 to insert the shaft 13 allows for installation of the shaft 13 without additional drilling, thereby simplifying the structure of the floating frame assembly 100, simplifying the installation of the shaft 13 and the guide wheel 20, and improving the ease of installation and removal of the shaft 13 and the guide wheel 20.

[0033] Of course, as an alternative embodiment, the shaft rod 13 can be installed without using the gap hole 111. For example, when there is no gap hole 111 in the guide bar 11, holes can be punched at corresponding positions in the guide bar 11 according to the arrangement density of the guide wheels 20, and the shaft rod 13 can be installed using the holes.

[0034] In some embodiments, the guide bar 11 is provided with a plurality of gap holes 111, which are spaced apart along the extension direction of the guide bar 11. The guide assembly 10 includes a plurality of shafts 13, which are spaced apart along the extension direction of the guide bar 11. The floating frame assembly 100 includes a plurality of guide wheels 20, which are disposed one-to-one with the plurality of shafts 13. In this manner, the plurality of guide wheels 20 extend along the direction of the transport channel 12, thereby continuously guiding the electroplating plate 200 during movement and improving the stability of the electroplating plate 200 during movement.

[0035] Optionally, gaps are left between the multiple guide wheels 20 to prevent interference between adjacent guide wheels 20 and ensure that each guide wheel 20 can operate independently. For example, the distance between two adjacent shafts 13 is greater than the diameter of the guide wheel 20. For example, the distance between two adjacent shafts 13 is 10 cm, and the diameter of the guide wheel 20 can be 40 mm. This ensures that there is a gap between the guide wheels 20.

[0036] In some embodiments, multiple guide wheels 20 can also be arranged at intervals in the vertical direction. For example, a guide wheel 20 is arranged between each two adjacent guide bars 11, so that the guide wheels 20 are arranged in the vertical direction to support and guide the electroplating plate 200 in the vertical direction.

[0037] In some embodiments, to prevent the shaft 13 from falling out of the guide bar 11, the guide assembly 10 further includes a position-limiting fixing sleeve 14, which is sleeved around the outer circumference of the shaft 13. Sleeving the position-limiting fixing sleeve 14 around the outer circumference of the shaft 13 increases the outer diameter of the shaft 13, thereby allowing the position-limiting fixing sleeve 14 to be stuck in the clearance hole 111. This prevents the shaft 13 from passing through the clearance hole 111 of the guide bar 11, thereby preventing the shaft 13 from falling out of the clearance hole 111 and improving the installation stability and reliability of the shaft 13.

[0038] In some embodiments, the position-limiting fixing sleeve 14 includes two first position-limiting sleeves 141 and a second position-limiting sleeve 142. The first position-limiting sleeves 141 are respectively disposed on the upper and lower sides of the guide wheel 20. At least one end of the shaft 13 extends through the guide bar 11, and the second position-limiting sleeve 142 is disposed on the portion of the shaft 13 extending through the guide bar 11. The first position-limiting sleeve 141 further limits the position of the guide wheel 20, preventing contact and collision between the upper or lower end of the guide wheel 20 and the upper and lower guide bars 11 of the guide wheel 20, thereby preventing wear between the guide wheel 20 and the guide bar 11. Furthermore, the first position-limiting sleeve 141 can limit the range of motion of the guide wheel 20, thereby improving the stability of the guide wheel 20 during use.

[0039] Optionally, the shaft rod 13 may be made of a carbon fiber rod material, which can prevent the shaft rod 13 from reacting with the solution in the copper tank 301 and thus prevent the shaft rod 13 from being corroded.

[0040] In some embodiments, the guide assembly 10 further includes a plurality of support rods 15, which are vertically spaced apart along the extension direction of the transport channel 12, and the guide bars 11 are fixed to the support rods 15. The support rods 15 can be used to support and fix the guide bars 11, so that the guide bars 11 are arranged in the copper groove 301 to play a guiding role. For example, perforations can be provided on the guide bars 11 for the support rods 15 to pass through, and the guide bars 11 are fixed in the support rods 15 using the perforations. The support rods 15 can be provided on the side of the guide bars 11 facing away from the transport channel 12, so as to avoid the support rods 15 blocking the passage of the electroplated plates 200 in the transport channel 12. When the guide assembly 10 is provided with a plurality of guide bars 11 in the vertical direction, the plurality of guide bars 11 are fixed on the support at intervals in the vertical direction.

[0041] Second, see Figure 5The present application further provides a vertical electroplating apparatus 300, which includes a copper tank 301, a transmission mechanism (not shown), and the floating frame assembly 100 provided in the first aspect. The floating frame assembly 100 is disposed in the copper tank 301, and the transmission mechanism is used to clamp the electroplating plate 200 to pass through the transportation channel 12. Utilizing the copper tank 301 and the transmission mechanism, the transmission mechanism can drive the electroplating plate 200 to pass through the copper tank 301, and the floating frame assembly 100 can guide the electroplating plate 200 to move in a vertical state in the copper tank 301, thereby achieving vertical and continuous electroplating of the electroplating plate 200.

[0042] In some embodiments, the vertical electroplating apparatus 300 further includes a drive member (not shown) connected to the floating frame assembly 100 for driving the floating frame assembly 100 to move vertically relative to the copper tank 301. By driving the floating frame assembly 100 to move up and down vertically, the height of the floating frame assembly 100 can be adjusted to accommodate the height of the electroplating plates 200 of different sizes, thereby providing guidance for the electroplating plates 200.
