Description

Technical Field

[0001] This utility model relates to a mask pressing device and an electroplating equipment, belonging to the technical field of electroplating equipment. Background Technology

[0002] With the continuous development of society and the advancement of science, electroplating has become a common processing technology in the field of metal processing. Currently, electroplating is mainly carried out using methods such as rack plating, barrel plating, continuous plating, brush plating, and double-sided plating. In the process of double-sided electroplating, upper and lower molds are usually set on both sides of the workpiece, and masks are covered on the upper and lower molds to shield the non-electroplated areas of the workpiece.

[0003] A pressing device is provided on one side of the upper mold. During the electroplating process, the upper mold can be lowered onto the surface of the workpiece and the mask can be squeezed to prevent the electroplating solution from seeping into non-electroplating areas. When it is necessary to change the workpiece, the upper mold can be lifted simply by pressing the device. In the prior art, the pressing device usually only has one cylinder, and the cylinder stroke is generally selected to facilitate the change of workpiece and mold. However, the long stroke cylinder has a long movement time and consumes more energy, which increases the electroplating time, reduces the electroplating efficiency, and thus increases the production cost of the product. Utility Model Content

[0004] This invention provides a mask pressing device and electroplating equipment, which solves the problems of long stroke cylinder movement time and high energy consumption, which increase electroplating time, reduce electroplating efficiency, and indirectly increase product production costs.

[0031] like Figures 1 to 4 As shown, this application provides a mask pressing device for use in a double-sided partial electroplating equipment. It presses down the upper mold portion of a double-sided electroplating mold and supports the upper mold portion, allowing for better fit between the upper and lower molds. The mask pressing device includes a drive mechanism 1, a first mounting plate 2, guide pillars 3, guide sleeves 4, a second mounting plate 5, a third mounting plate 6, and a fixing plate 7. The drive mechanism 1 consists of two cylinders: a first cylinder 101 and a second cylinder 102, connected in series. The first cylinder 101 drives the second cylinder 102 in reciprocating motion. The first cylinder 101 is connected to the first mounting plate 2 and drives the first mounting plate 2 in reciprocating motion. A fourth mounting plate 11 is provided at the end of the first cylinder 101 facing away from the first mounting plate 2, and the first cylinder 101 is fixedly connected to the fourth mounting plate 11. The first mounting plate 2 is surrounded by guide posts 3 and guide sleeves 4. The guide sleeves 4 are fitted around the outer periphery of the guide posts 3 and are slidably connected to the guide posts 3. The second mounting plate is fitted around the outer periphery of the guide sleeves 4 and is fixedly connected to the guide sleeves 4. One end of the guide posts 3 is fixedly connected to the fourth mounting plate 11. The first cylinder 101 drives the first mounting plate 2 to move, causing the guide sleeves 4 to slide along the guide posts 3. The guide posts 3 and guide sleeves 4 provide guidance for the movement of the first mounting plate 2.

[0032] In some embodiments, the second cylinder 102 is fixedly connected to the end of the first mounting plate 2 opposite to the first cylinder 101. The side of the second cylinder 102 opposite to the first mounting plate 2 is connected to the second mounting plate 5. A guide post 3 is mounted on the side of the second mounting plate 5 opposite to the second cylinder 102, and a guide sleeve 4 is fitted around the outer periphery of the guide post 3. A third mounting plate 6 is fitted around the outer periphery of the guide sleeve 4. The end of the guide post 3 opposite to the second mounting plate 5 is connected to a fixed plate 7. A support post 12 is provided between the first mounting plate 2 and the third mounting plate 6. The support post 12 is installed at the four corners of the first mounting plate 2 and the third mounting plate 6, so that the first mounting plate 2 and the third mounting plate 6 are connected as a whole. When the first cylinder 101 drives the first mounting plate 2 to move, since the two ends of the support post 12 are fixedly connected to the first mounting plate 2 and the third mounting plate 6 respectively, the third mounting plate 6 can move together with the first mounting plate 2. After the first mounting plate 2 moves to the designated position, the second cylinder 102 drives the second mounting plate 5 to move, so that the guide post 3 on the second mounting plate 5 can move along the guide post 4, thereby pushing the fixed plate 7 to move. Using two cylinders in series can not only increase the movement distance of the fixed block 7, but also provide greater thrust.

[0033] In some embodiments, an upper mold 8 of an electroplating mold is mounted on the side of the fixing plate 7 opposite to the second cylinder 102, and a mask is mounted on the side of the upper mold 8 opposite to the fixing plate 7. Locking buckles 10 are mounted on both sides of the fixing plate 7 and the upper mold 8, dividing the locking buckles 10 into two parts, which are respectively mounted on the fixing member 7 and the upper mold 8, facilitating disassembly and replacement of the upper mold 8, and applicable to various specifications of upper molds 8.

[0034] In some embodiments, both the first cylinder 101 and the second cylinder 102 are short-stroke cylinders. The use of two cylinders in series provides a longer stroke while saving energy and improving electroplating efficiency. When changing electroplated workpieces, because the workpieces are thin, the space required for replacement is small. Therefore, only the second cylinder 102 needs to be driven to lift the upper mold 8, shortening the cylinder stroke, reducing energy consumption, saving the time for the cylinder to move up and down, and also shortening the electroplating time for a single workpiece, thus improving electroplating efficiency. When changing the upper and lower molds, which require more space, simultaneously activating the first cylinder 101 and the second cylinder 102 to lift the upper mold 8 provides a larger operating space, facilitating the replacement of the upper and lower molds.

[0035] Optionally, four guide pillars 3 and guide sleeves 4 are provided between the first mounting plate 2 and the fourth mounting plate 11, and are installed at the four corners of the first mounting plate 2. Two guide pillars 3 and guide sleeves 4 are provided between the second mounting plate 5 and the third mounting plate 6, and are installed on both sides of the second mounting plate 5. The guide pillars 3 and guide sleeves 4 can guide the movement of the upper mold 8, so that the upper mold 8 fits snugly with the lower mold. At the same time, the use of two cylinders in series can not only provide a longer stroke, but also provide greater pressure, so that the upper mold 8 fits snugly with the lower mold, and the masks on both sides of the workpiece fit snugly with the workpiece, preventing the electroplating solution from leaking from the mask edges, contaminating the non-electroplated areas, and affecting the quality of the electroplated product.

[0036] In addition, this application also provides an electroplating apparatus that uses the aforementioned mask pressing device. The electroplating apparatus further includes a truss 9, which is mounted on a support of the electroplating apparatus. The mask pressing device is mounted on one side of the truss 9 via a fourth mounting plate 11. Since the electroplating apparatus uses the mask pressing device described above, it has the advantages mentioned above.

[0037] The working principle of this utility model is as follows: The mask pressing device includes a first cylinder 101 and a second cylinder 102, which are connected in series. The first cylinder 101 drives the first mounting plate 2, which in turn drives the second cylinder 102 and the upper mold 8 to move. After the first cylinder 101 moves to the designated position, the second cylinder 102 continues to push the second mounting plate 5 to move. The second mounting plate 5 pushes the upper mold 8 to continue moving until it abuts against the lower mold. By setting two cylinders in series and cooperating with multiple mounting plates, guide pillars, and guide sleeves, the mask pressing device enables the upper mold 8 of the electroplating equipment to move stably until it fits against the lower mold of the electroplating equipment. The series connection of the two cylinders increases the pressure on the upper mold 8, making the upper mold and lower mold tightly connected, and ensuring that the silicone mask on both sides of the workpiece is tightly connected to the workpiece, preventing the electroplating solution from leaking from the edge of the mask, contaminating the non-electroplated area, and affecting the quality of the electroplated product. When only the electroplated workpiece needs to be replaced, only the second cylinder 102 needs to be driven to move up and down, which shortens the cylinder stroke, reduces energy consumption, saves the time of cylinder movement, shortens the electroplating time of a single workpiece, and improves electroplating efficiency.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
