[0001] The utility model relates to the technical field of water jet design, in particular to a water jet and a horizontal copper deposition production line formed thereby. Background Art

[0002] In the process of PCB board processing, a copper deposition process is required. Before the PCB board enters the horizontal copper deposition production line, it is necessary to clean the surface of the PCB board to remove the oil stains, oxide layers, impurities and imprints during the handling process. In the prior art, a water jet is used to clean the surface of the PCB board.

[0003] The water jet in the prior art includes a water inlet pipe and a water outlet. Among them, the water outlets are usually distributed in a matrix form of multiple rows and multiple columns. Under the water inlet pressure of the water inlet pipe, the water flows out of the water outlets at a certain pressure to achieve the function of cleaning the surface of the PCB board.

[0004] The water jet of the water washing tank of the existing horizontal copper deposition line is in a flat state, and there are problems such as insufficient pressure in the cleaning effect of the board surface, and it cannot better remove the oil stains and oxide layers on the board surface. After the production board enters the copper cylinder, there are defects such as residual oxide layers on the board surface and finger prints after manual handling; therefore, it is necessary to improve the water jet to ensure that it can achieve a better cleaning effect. Summary of the Utility Model

[0005] In view of this, this application aims to solve the problems in the related technologies to at least a certain extent. One of the purposes of this application is to provide a water jet that uses a partition to separate the knife body chamber, ensuring that the water pressure at the water outlet is increased, and the water pressure uniformity at the water outlets in each position can be ensured, achieving a pressurized and uniform cleaning effect.

[0006] To achieve the above purpose, this application adopts the following technical solutions: A water jet includes a cuboid knife body chamber. M uniformly distributed partitions are arranged in parallel in the first side surface of the knife body chamber. M + 1 water outlets are arranged at intervals with M uniformly distributed partitions; M is an integer greater than 0;

[0007] A water inlet is arranged in the second side surface of the knife body chamber. The second side surface is opposite to the first side surface, and the partition does not abut against the second side surface.

[0008] Further, the height of the partition is equal to 1 / 4 of the distance between the first side surface and the second side surface.

[0009] Further, the water outlet includes a plurality of uniformly arranged water outlet holes, and the plurality of water outlet holes are distributed along the extension direction of the partition in the first side surface.

[0010] Further, the partitions are two arranged in parallel, and the water outlets are three rows arranged in parallel.

[0011] Further, a third side and a fourth side are provided between the first side and the second side. The first side, the second side, the third side and the fourth side enclose a tool body chamber, and the widths of the first side, the second side, the third side and the fourth side are the same. The partition extends along the long side direction of the first side.

[0012] Further, it includes a water inlet pipe. One end of the water inlet pipe is provided with a water inlet, the other end of the water inlet pipe is sealed, and an overflow port is provided on the side of the water inlet pipe. A notch is provided on the second side of the tool body chamber, and the notch is adapted to the overflow port.

[0013] Further, the water inlet pipe is of a cylindrical structure. A square notch is provided on the second side of the tool body chamber. The square notch is nested on the side of the cylindrical water inlet pipe, and the overflow port is located inside the square notch.

[0014] The second object of the present application is to provide a horizontal copper deposition production line, including a water knife as described above.

[0015] The above technical solutions provided by the embodiments of the present application have the following advantages compared with the prior art: In the water knife of the present application, a tool body chamber in the shape of a cuboid is included. M evenly distributed partitions are arranged in parallel in the first side of the tool body chamber, and M + 1 water outlets are arranged at intervals with the M evenly distributed partitions; M is an integer greater than 0; a water inlet is provided in the second side of the tool body chamber, the second side is arranged opposite to the first side, and the partition does not abut against the second side. Since the partition abuts against the first side and does not abut against the opposite second side, and the water inlet is located in the second side, the water entering the tool body chamber through the water inlet is mixed together and will not be separated by the partition; as the water in the water inlet continuously enters, the water level inside the tool body chamber gradually rises until the water level rises to the position flush with the bottom of the partition. At this time, the partition divides the water at the bottom of the tool body chamber into multiple chambers. When the water flows from the water inlet to the water outlet, especially when flowing between the partitions, in addition to being affected by the water pressure at the water inlet, it will also be affected by the extrusion force from the side partitions, thereby enhancing the water pressure at the water outlet. Compared with the water knife structure without partitions, the water pressure at the water outlet in the present application can be enhanced, thereby improving the cleaning effect. The structure of the present application is simple and only requires adding partitions inside the original tool body chamber, without the need for re - design and manufacturing, reducing the production cost of the water knife. At the same time, the partition makes the water pressure at the water outlet more uniform and can enhance the water outlet pressure, achieving a pressurized and uniform cleaning effect.

[0016] A horizontal copper deposition line provided by the present application includes the water knife as described above. The water knife is arranged on the inlet side of the horizontal copper deposition tank. The water knife cleans the PCB board entering the horizontal copper deposition tank to ensure the oil stains, residual oxide layers and imprints generated during the handling process on the surface of the PCB board, and improves the copper deposition effect.

[0029] Embodiment 1

[0030] As Figures 1 - 4 shown, a water jet proposed by the present application includes a cuboid tool body chamber. M uniformly distributed partitions 21 are arranged in parallel in the first side surface 11 of the tool body chamber, and M + 1 water outlets are arranged at intervals with the M uniformly distributed partitions 21; M is an integer greater than 0; an inlet 32 is arranged in the second side surface 12 of the tool body chamber, the second side surface 12 is arranged opposite to the first side surface 11, and the partition 21 is not in contact with the second side surface 12.

[0031] Since the partition 21 abuts against the first side surface 11 and does not abut against the opposite second side surface 12, and the water inlet 32 is located in the second side surface 12, the water entering the tool body chamber through the water inlet 32 is mixed together and will not be separated by the partition 21. As the water continuously enters through the water inlet 32, the water level inside the tool body chamber gradually rises. When the water level rises to the position flush with the bottom of the partition 21, the partition 21 divides the water at the bottom of the tool body chamber into multiple chambers. When the water flows from the water inlet 32 to the water outlet, especially when flowing between the partitions 21, in addition to being affected by the water pressure at the water inlet 32, it will also be subjected to the extrusion force from the side partition 21, thereby enhancing the water pressure at the water outlet. Compared with the water knife structure without the partition 21, the water pressure at the water outlet in this application can be enhanced, thereby improving the cleaning effect.

[0032] The structure of this application is simple. It only needs to add a partition 21 inside the original tool body chamber to achieve, without the need for re - design and manufacturing, reducing the production cost of the water knife. At the same time, the partition 21 makes the water pressure at the water outlet more uniform and can enhance the water outlet pressure, achieving a pressurized and uniform cleaning effect.

[0033] Embodiment 2

[0034] As Figures 1 - 4 shown, a water knife proposed in this application includes a cuboid tool body chamber. M uniformly - distributed partitions 21 are arranged in parallel in the first side surface 11 of the tool body chamber, and M + 1 water outlets are arranged at intervals with M uniformly - distributed partitions 21; M is an integer greater than 0; a water inlet 32 is arranged in the second side surface 12 of the tool body chamber, the second side surface 12 is arranged opposite to the first side surface 11, and the partition 21 does not abut against the second side surface 12.

[0035] This application defines that the height of the partition 21 is equal to 1 / 4 of the distance between the first side surface 11 and the second side surface 12. Assuming the distance between the first side surface 11 and the second side surface 12 is X, then the height of the partition 21 is 1 / 4X. At the same time, the top end of the partition 21 is fixedly connected to the first side surface 11, and the distance between the bottom end of the partition 21 and the second side surface 12 is 3 / 4X.

[0036] In this embodiment, the second side 12 is defined as the bottom surface of the cutter body chamber, and the first side 11 is defined as the top surface of the cutter body chamber. At the 3 / 4 position at the bottom of the cutter body chamber, the water flow is not divided and is located at the bottom of the cutter body chamber as a unified whole. At the 1 / 4 position at the bottom of the cutter body chamber, the water flow is separated by the partition 21. As the water source continuously enters from the water inlet 32, the water level inside the cutter body chamber gradually rises. When the water level rises to the position flush with the bottom of the partition 21, the partition 21 evenly divides the water at the bottom of the cutter body chamber into M + 1 chambers. When the water flow flows from the water inlet 32 to the water outlet, especially when flowing between the partitions 21, in addition to being affected by the water pressure at the water inlet 32, it will also be affected by the extrusion force from the side partition 21, thereby enhancing the water pressure at the water outlet. This application defines the height of the partition 21 to be equal to 1 / 4 of the distance between the first side 11 and the second side 12, which can ensure that the water flow is fully mixed and then divided within a specific range. By dividing the ratio between the mixed water flow and the divided water flow, it can ensure that the water pressure at the water outlet is enhanced and the cleaning efficiency is improved.

[0037] In this application, the M partitions 21 are partitions 21 evenly distributed along the first side 11, which can ensure that the cutter body chamber is evenly divided into M + 1 chambers. In this application, the cutter body chamber is a rectangular cutter body chamber, that is, the first side 11 and the second side 12 are parallel to each other, and a third side 13 and a fourth side 14 are also provided between the first side 11 and the second side 12. For example, if there are 3 partitions 21, then M + 1 chambers are formed between the third side 13, the fourth side 14 and the M partitions 21, and M + 1 water outlets are correspondingly arranged in the M + 1 chambers. Preferably, they can be arranged at the middle positions of the M + 1 chambers.

[0038] In this application, a third side 13 and a fourth side 14 are provided between the first side 11 and the second side 12. The first side 11, the second side 12, the third side 13 and the fourth side 14 enclose the cutter body chamber, and the widths of the first side 11, the second side 12, the third side 13 and the fourth side 14 are the same. The partition 21 extends along the long side direction of the first side 11.

[0039] The volume of each chamber is the same, which can ensure that the water outlet pressure of each water outlet is the same, ensure that the pressure on each position of the plate during the cleaning process by the water knife is the same, and ensure the uniformity of the cleaning effect.

[0040] The water outlet provided in each chamber of the present application includes a plurality of water outlet holes 22 arranged evenly, and the plurality of water outlet holes 22 are distributed in the first side surface 11 along the extending direction of the partition plate 21. Here, the extending direction of the partition plate 21 refers to the extending direction of the partition plate 21 in the direction parallel to the plane where the first side surface 11 and the second side surface 12 are located. Correspondingly, both sides of the partition plate 21 in the extending direction can be in contact with the side surface of the tool body chamber, so that M + 1 relatively enclosed chambers can be formed at the water outlet, so as to better achieve the purpose of pressurizing the water outlet.

[0041] As another embodiment, both sides of the partition plate 21 in the extending direction are not in contact with the side surface of the tool body chamber. Correspondingly, water outlet holes 22 do not need to be provided at the positions where the partition plate 21 does not extend, and the purpose of pressurizing the water outlet can also be achieved.

[0042] As Figure 1 and Figure 2 shown, the present application can be provided with two partition plates 21 arranged in parallel, and the water outlets are arranged in three rows in parallel. In actual operation, the number of partition plates 21 can be reasonably set according to the width of the first side surface 11.

[0043] The water jet of the present application further includes a water inlet pipe 31. One end of the water inlet pipe 31 is provided with a water inlet 32, the other end of the water inlet pipe 31 is hermetically arranged, a water overflow port 33 is arranged on the side surface of the water inlet pipe 31, a notch is arranged on the second side surface 12 of the tool body chamber, and the notch is adapted to the water overflow port 33.

[0044] Specifically, the water inlet pipe 31 is of a cylindrical structure, a square notch is arranged on the second side surface 12 of the tool body chamber, the square notch is nested on the side surface of the cylindrical water inlet pipe 31, and the water overflow port 33 is located inside the square notch.

[0045] In the present application, the notch on the side of the water inlet pipe 31 is hermetically connected to the directional notch in the tool body chamber, and specifically, the hermetic connection can be achieved by means such as welding and injection molding. The water in the water inlet 32 first enters the water inlet pipe 31 and then flows out from the overflow port into the tool body chamber. At the 1 / 4 position at the bottom of the tool body chamber, the water flow is separated by the partition plate 21. As the water continuously enters from the water inlet 32, the water level inside the tool body chamber gradually rises. When the water level rises to the position flush with the bottom of the partition plate 21, the partition plate 21 evenly divides the water at the bottom of the tool body chamber into M + 1 chambers. When the water flow flows from the water inlet 32 to the water outlet, especially when flowing between the partition plates 21, in addition to being affected by the water pressure at the water inlet 32, it will also be subjected to the extrusion force from the side partition plate 21, thereby enhancing the water pressure at the water outlet. In the present application, it is defined that the height of the partition plate 21 is equal to 1 / 4 of the distance between the first side 11 and the second side 12, which can ensure that the water flow is fully mixed and then divided within a specific range. By dividing the ratio between the mixed water flow and the divided water flow, it can ensure that the water pressure at the water outlet is enhanced and the cleaning efficiency is improved.

[0046] At the same time, the volume of each chamber is the same, which can ensure that the water outlet pressure of each water outlet is the same, ensure that the pressure on each position of the plate during the cleaning process by the water knife is the same, and ensure the uniformity of the cleaning effect.

[0047] The present application also provides a horizontal copper deposition production line, including a water knife as described above. Among them, the horizontal copper deposition production line further includes a copper deposition tank. The water knife is arranged at the inlet position of the copper deposition tank. Transmission lines are arranged at both the inlet and outlet of the copper deposition tank. The transmission lines are used to realize the loading and unloading of the PCB board. Specifically, the water knife is arranged above the transmission line, and the water outlet is arranged facing the transmission line. When the PCB board moves along the transmission line to the inlet position of the copper deposition tank, by controlling the water pressure at the water inlet 32, the jet water pressure of the water outlet can be adjusted to achieve the effect of cleaning the surface of the PCB board. The water knife cleans the PCB board entering the horizontal copper deposition tank to ensure the oil stains, residual oxide layers and imprints generated during the handling process on the surface of the PCB board, and improves the copper deposition effect.

[0048] It can be understood that the above embodiments only represent the preferred embodiments of the present application, and the description is relatively specific and detailed, but it cannot be construed as a limitation to the patent scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, the above technical features can be freely combined, and several deformations and improvements can also be made, which all belong to the protection scope of the present application. Therefore, all equivalent transformations and modifications made to the scope of the claims of the present application shall fall within the scope covered by the claims of the present application.
