[0028] A horizontal electroplating fixture is a device used in horizontal PCB electroplating equipment to clamp the workpiece horizontally and transport it to a chemical bath for electroplating. The equipment features a spray device at the anode reaction site. The spray device contains an anode mesh for conductivity and an anode mesh plate for support and light transmission. Multiple anode spray devices are typically arranged horizontally within the electroplating bath, along the direction of travel of the workpiece to be plated. These devices are immersed in chemical bath water, with the workpiece moving horizontally between the two rows.
[0029] Most existing anode mesh plates have a matrix of circular holes for light transmission. However, since the circular head holes cannot be arranged tightly, there are always gaps between the holes, resulting in a large number of blocked areas in each row and insufficient light transmittance. As a result, during the electroplating process, the plated parts may have thicker coatings in some areas and thinner coatings in others, resulting in uneven coating on the final plated parts. Furthermore, the existing anode mesh plates have a relatively small number of rollers installed, and these are only installed on the lower anode mesh plate, while the upper anode mesh plate does not have rollers. When multiple spray devices are arranged, gaps will exist between the anode meshes. When the plated parts are transported horizontally, they can easily get stuck in the gaps between two adjacent anode meshes while passing through these gaps, resulting in a plate jam.
[0030] The utility model provides an anode mesh plate 100 .
[0031] See also Figure 1-4In one embodiment of the present invention, the anode mesh plate 100 includes: a main body 1 and a roller 2; the main body 1 is provided with a plurality of meshes 11 and a plurality of first spray holes 12, each mesh 11 is arranged in a hexagonal shape, and the plurality of meshes 11 are arranged in a honeycomb array on the main body 1, and the plurality of first spray holes 12 are arranged at intervals on the main body 1, and the main body 1 has a spray side facing the workpiece 304 to be plated and spraying the workpiece 304 to be plated; the roller 2 is installed on the spray side of the main body 1 for contacting the workpiece 304 to be plated.
[0032] In this embodiment, the body 1 of the anode mesh plate 100 is arranged in a horizontal direction to be parallel to the workpiece 304 to be plated, so that the workpiece 304 to be plated can slide between the multiple anode mesh plates 100 along a preset direction. The mesh 11 is used to increase the light transmittance when the workpiece 304 to be plated is electroplated. The electroplating anode with good light transmittance can improve the efficiency and quality of the electroplating process. The electroplating anode plays a catalytic role in the electroplating process, and a thin layer of metal or alloy is plated on the metal surface through electrolysis. The light transmittance provided by the mesh 11 on the anode mesh plate 100 can help the uniform deposition of the metal during the electroplating process. A regular hexagonal mesh 11 is set on the anode mesh plate 100. The angular characteristics of the regular hexagon are utilized to enable three adjacent meshes 11 to be closely arranged, so that the meshes 11 can be closely arranged in a honeycomb array on the main body 1 to reduce the obstruction area between adjacent meshes 11, which helps to evenly illuminate the electroplating surface with light, ensure uniform deposition of the coating, and avoid the problem of local excessive thickness or thinness. In addition, the hexagonal shape has more sides than other shapes that can be closely arranged, is closer to a circle, and has greater light transmittance. Compared with a regular triangle or a square, it is easier to ensure the light transmittance of each segment. The good light transmittance of the mesh 11 can also reduce shadow areas during the electroplating process, avoid the formation of rough or uneven surfaces, and improve the quality of electroplating. The first spray hole 12 is used to spray the reaction solution. During electroplating, the outlet of the pipeline through which the reaction solution flows is connected to the first spray hole 12, so that the reaction solution is sprayed through the first spray hole 12 onto the surface of the workpiece 304 to be plated. The provision of the first spray hole 12 can expand the spray range of the reaction solution, thereby spraying the solution more evenly on the surface of the workpiece 304 to be plated, allowing the metal ions to adhere more evenly to the surface of the workpiece 304 to be plated, thereby reacting to form a more uniform coating.
[0033] In this embodiment, a roller 2 is further provided on the anode mesh plate 100. Since the workpiece 304 to be plated is moved in the horizontal direction by clamping one end of the workpiece 304 with a clamp and moving it horizontally, the workpiece 304 to be plated is usually in the shape of a plate and is prone to slight bending or tilting under the action of gravity. A plurality of rollers 2 are provided, and the outer periphery of the roller 2 is higher than the surface of the anode mesh plate 100, which can play a certain supporting and guiding role for the workpiece 304 to be plated when the workpiece 304 to be plated moves horizontally. When the workpiece 304 to bend or tilt downward in the horizontal direction, the workpiece 304 to be plated will first come into contact with the roller 2 and be connected to the roller 2 in a rolling manner, thereby sliding on the multiple spliced anode mesh plates 100 under the action of the roller 2, and will not get stuck in some gaps formed by the mechanical structure, causing the phenomenon of plate jamming. In addition, since the roller 2 and the workpiece 304 are in rolling contact, the force generated on the surface of the workpiece 304 is rolling friction, which has a smaller impact on the surface of the workpiece 304, thereby preventing the surface of the workpiece 304 from being scratched and damaged.
[0034] The technical solution of the present invention is to set a plurality of meshes 11 for light transmission in the main body 1 of the anode mesh plate 100. Each mesh 11 is set in a hexagon and arranged in a honeycomb array, so that adjacent meshes 11 can fit tightly due to the characteristics of the hexagonal shape and the honeycomb array, minimizing the blocking area between the holes, thereby increasing the light transmittance of the anode mesh plate 100 and making the workpiece 304 to be plated more uniformly; and by setting rollers 2 in the anode mesh plate 100, the workpiece 304 to be plated can be supported by the rollers 2 and slide between the rollers 2 during transportation, thereby avoiding the workpiece 304 to be plated being stuck by the remaining structures in the moving direction and causing the plate to be stuck.
[0035] See Figure 1 In one embodiment, the body 1 further comprises a roller groove 13, in which the roller 2 is rotatably mounted. The roller grooves 13 are evenly spaced on the spray side of the body 1. The roller 2 comprises a rotating shaft and a runner that rotates about the rotating shaft. The rotating shaft extends perpendicular to the direction of movement of the workpiece 304 to be plated and is mounted in the roller groove 13, such that the rotation direction of the runner is the same as the movement direction of the workpiece 304 to be plated. The depth of the roller groove 13 is less than the outer diameter of the runner. Therefore, when the roller 2 is mounted in the roller groove 13, the outer wall of the runner protrudes from the surface of the anode mesh plate 100, thereby abutting against the workpiece 304 to provide support and guidance for the workpiece 304.
[0036] In one embodiment, the plurality of first spray holes 12 are divided into multiple rows of spray hole groups, each row of spray hole groups including at least two spray holes spaced apart along a first direction. The multiple rows of spray hole groups are spaced apart along a second direction, with any two adjacent rows of spray hole groups staggered, such that the first direction intersects the second direction. Arranging the first spray holes 12 in rows allows the reaction solution to be sprayed over a larger and wider range. The staggered arrangement of the spray hole groups in each row enables the apparatus to spray the reaction solution more evenly onto the workpiece 304 to be plated, thereby promoting a more complete electroplating reaction and forming a more uniform coating.
[0037] In one embodiment, each first spray hole 12 is elongated and arranged at an angle relative to the first and second directions. The elongated first spray holes 12 are located at the nozzle 2021. After the reaction solution is sprayed from the nozzle 2021 through the elongated first spray holes 12, it is blocked by the walls of the elongated first spray holes 12. Part of the sprayed reaction solution collides with the walls of the first spray holes 12, thereby accelerating and redirecting the reaction solution. This allows the reaction solution to be sprayed over a wider and more uniform range, facilitating the formation of a more uniform coating.
[0038] In one embodiment, a first mounting groove is provided on the side of the body 1 facing away from the roller 2, and the first mounting groove is used to mount the anode mesh 201. In this embodiment, multiple first mounting grooves are provided on the side of the body 1 facing away from the roller 2, and the first mounting grooves are used to mount the anode mesh 201. The anode mesh 201 has a shape that matches the multiple first mounting grooves and is fixed in the first mounting grooves by means of a press code and fasteners. Arranging the anode mesh 201 into multiple pieces enables the current to be controlled and adjusted in different zones, thereby better controlling the electroplating uniformity of the final coating.
[0039] In one embodiment, the body 1 has a first side wall 14 and a second side wall 15 arranged opposite to each other. The first side wall 14 and / or the second side wall 15 are provided with a second mounting groove 16. The second mounting groove 16 is used to mount a guide block 17. The guide block 17 is used to guide the workpiece 304 to be plated. A plurality of second mounting grooves 16 are arranged at intervals along the first side wall 14 and / or the second side wall 15. A guide block 17 is provided in at least one second mounting groove 16. When a plurality of anode mesh plates 100 are arranged transversely along the moving direction of the workpiece 304 to be plated, there will be a gap between two adjacent anode mesh plates 100. The guide block 17 is provided at the edge of the anode mesh plate 100. The guide block 17 can guide the anode mesh plate 100 when the workpiece 304 to be plated passes through the gap between two adjacent anode meshes 201, thereby preventing the workpiece 304 to be plated from being stuck when passing through the gap, thereby affecting the electroplating process.
[0040] See Figure 3 、 4The present invention also proposes an anode spray device 200, which includes: an anode mesh plate 100, an anode screen 201, a spray assembly 202, and a conductive assembly 203. The specific structure of the anode mesh plate 100 refers to the above embodiment. Since the anode spray device 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the anode mesh plate 100 is any of the anode mesh plates 100 mentioned above; the anode screen 201 is detachably mounted on the anode mesh plate 100; the spray assembly 202 is mounted on the side of the anode screen 201 away from the anode mesh plate 100; and the anode screen 201 is connected to the rectifier 302 via the conductive assembly 203.
[0041] In this embodiment, the anode mesh 201 is used to be immersed in an electrolyte containing the plating metal ions along with the workpiece 304 to be plated. By connecting the anode mesh 201 to a power source, a potential difference is established between the anode mesh 201 and the workpiece 304 to be plated, thereby initiating an electrolytic reaction and coating the outer surface of the workpiece 304 with a metal coating. The spray assembly 202 is used to spray the reaction solution toward the workpiece 304 to be plated. The spray assembly 202 includes multiple spray pipes, each of which is equipped with multiple nozzles 2021. The spray pipes are connected to the reaction solution and spray the reaction solution through the nozzles 2021. The conductive assembly 203 is connected to the rectifier 302 at one end and to the anode mesh 201 at the other end to supply power to the anode mesh 201, enabling electroplating.
[0042] In one embodiment, the anode mesh 201 has second spray holes 2011 at positions corresponding to the first spray holes 12. A plurality of nozzles 2021 are provided on a side of the spray assembly 202 proximate the anode mesh 201. The nozzles 2021 are in one-to-one communication with the first spray holes 12 via the second spray holes 2011. The anode mesh 201 has second spray holes 2011 at positions corresponding to the first spray holes 12, which are identical in shape and size to the first spray holes 12. When the anode mesh 201 is installed in the mounting cavity of the anode mesh plate 100, the second spray holes 2011 can overlap with the first spray holes 12, allowing liquid sprayed from the nozzles 2021 to simultaneously and sequentially pass through the second spray holes 2011 and the first spray holes 12 and be sprayed onto the workpiece 304 to be plated.
[0043] In one embodiment, a plurality of anode meshes 201 are provided, and the conductive assembly 203 includes a plurality of conductive flats, which are provided in a one-to-one correspondence with the anode meshes 201. One end of each conductive flat is connected to the anode mesh 201, and the other end is connected to the rectifier 302. The anode meshes 201 are provided in multiple pieces, and the conductive flats are connected to each piece of anode mesh 201 in a one-to-one correspondence. Such a configuration enables the magnitude of the current to be controlled and adjusted by partition, thereby better controlling the electroplating uniformity of the final coating. The anode mesh 201 has a shape that matches the mounting cavity and is installed in the first mounting cavity by means of a pressure code and a connector 2012, thereby preventing the anode mesh 201 from falling out of the first mounting cavity.
[0044] The present invention also proposes a horizontal electroplating equipment, including: an electroplating cylinder 301 and at least two groups of anode spray devices 200, the at least two groups of anode spray devices 200 are installed at intervals in the electroplating cylinder 301, the spray sides of the at least two groups of anode spray devices 200 are arranged opposite to each other, and an electroplating cavity for accommodating the workpiece 304 to be plated is formed between any two groups of anode spray devices 200 arranged opposite to each other, and the at least two groups of anode spray devices 200 adopt any of the above anode spray devices 200.
[0045] In an embodiment of the present invention, at least two groups of anode spray devices 200 are spaced apart in the height direction, with each two groups of anode spray devices 200 forming an anode spray device group 200. The spray sides of each anode spray device group 200 are positioned relative to each other so that both the upper and lower sides of the workpiece 304 to be plated disposed therein can be uniformly plated. In this embodiment, multiple anode spray device groups 200 are spaced apart in the horizontal direction, with each anode spray device group 200 being closely arranged at the same height to reduce gaps between the groups, allowing the workpiece 304 to be plated to be continuously plated uninterruptedly during movement until the plating is complete.
[0046] In this embodiment, the anode spray device 200 is the anode conductive portion of the equipment. After assembly, it is fixed to the electroplating cylinder 301. Then, a reaction solution is added to the electroplating cylinder 301, and the anode spray device 200 is immersed in the reaction solution. The workpiece 304 to be plated is placed between the anode spray device 200 via a horizontal electroplating fixture 303. Then, power is applied to the anode spray device 200 to conduct electricity and electroplate the workpiece 304. Among them, the anode mesh plate 100 is an auxiliary device used in the horizontal electroplating equipment to assist the electroplating process. Its function is to provide a uniform current density distribution for the workpiece during the electroplating process, and to decompose elemental particles in the reaction solution and attach them to the workpiece 304 to be plated.
