Description

Technology Field

[0001] The present invention relates to a component pickup cylinder for a chrome plating system, and more specifically, to a component pickup cylinder for a chrome plating system capable of preventing the inflow of plating solution by installing a tip and a mask holder at the bottom of the cylinder tube to block the inflow of plating solution into the cylinder tube, and forming irregularities on the bottom surface of the tip to increase the surface area so as to facilitate contact with anions or cations, thereby improving plating quality. Background Technology

[0002] Plating involves forming a thin film of another material to improve the surface condition of an object for various purposes. There are various types, such as tin plating, chrome plating, zinc plating, and copper plating, with electroplating through the electrolysis of an aqueous solution being the most widely used.

[0003] In particular, electroplating has advantages such as not requiring high-temperature treatment, allowing for precise control of thickness and weight, and producing a smooth, light-reflecting, and aesthetically pleasing surface after completion.

[0004] Among them, chrome plating uses CrO3 and H2SO4 as the plating solution, and the electrode connected to the cathode is connected to the workpiece in the plating solution, and the workpiece is immersed in the plating solution to proceed with the plating.

[0005] At this time, the electrode and the workpiece are electrically connected through a jig and the workpiece is fixed so that it does not fall off. A typical jig is shaped like a hook to hang the workpiece and perform plating.

[0006] However, since the workpiece to be plated is a small part and cannot be hung on a jig, a pickup cylinder for adsorbing and transporting small parts has been disclosed.

[0007] As examples of such pickup cylinders, Korean registered patent No. 10-2022627, a workpiece supply and discharge facility, and Korean registered patent No. 10-0729271, a continuous plating facility are disclosed.

[0008] The above-described workpiece supply and discharge facility comprises: a separation device (100) that separates the workpiece and the interleaving paper by vacuum suctioning them from a cartridge containing a load in which interleaving paper is placed between each of a plurality of workpieces as shown in FIG. 1; a rotation device (200) that rotates the workpiece removed from the cartridge by the separation device to stand upright, and a moving device (300) that picks up the workpiece from the rotation device and moves it to a plating support pallet; thereby supplying the workpiece from the cartridge to the support pallet, and after the workpiece is plated, the separation device, the rotation device, and the moving device operate in reverse order and, when each operates in reverse, discharge the workpiece from the support pallet to the cartridge.

[0009] As shown in FIG. 2, the above continuous plating equipment is composed of a vacuum pad portion (121) that adsorbs one side of a lead frame (400), a first air cylinder (122) installed on the upper part of the vacuum pad portion (121) to lift the lead frame (400) adsorbed on the vacuum pad portion (121) upward, a second air cylinder (124) that is linked with the first air cylinder (122) and rotates the lead frame (400) by 90 degrees, and a clamp opening member (126) that supports the elastic part of the clamp (130) to widen the gap between the conveyor belt (112) and the lower part of the clamp (130) so as to insert the lead frame (400) rotated by 90 degrees between the conveyor belt (112) and the lower part of the clamp (130) mounted on the conveyor belt (112).

[0010] However, these conventional plating facilities use a vacuum to transport parts, but they have the problem of being unable to pick up small parts because they can only plate relatively large parts. Prior art literature

It is characterized by including a mask holder that is press-fitted and fixed to the bottom of the tip to prevent the plating solution from flowing into the cylinder tube and to guide the small part, and has a part insertion groove formed in the center of the bottom surface into which the small part is inserted.

[0017] Here, the tip forms irregularities on the bottom surface to increase the surface area and facilitate contact with anions or cations, thereby improving plating quality.

[0018] In addition, the tip is bolted to the cylinder tube so that its height is adjusted, so that it is attached by the magnetic force of the small part when the magnet descends, and the small part is detached when the magnet ascends.

[0028] First, the air cylinder (10) is a double-acting type that moves back and forth, and a plurality of them are installed on a pickup plate (P) that moves up and down and forward and backward directions.

[0029] And, the magnetic holder (20) is pin-coupled vertically to the end of the piston (11) of each air cylinder (10) and moves up and down together with the piston (11). At this time, it is preferable that the magnetic holder (20) be formed of a non-magnetic metal.

[0030] Additionally, the magnetic (30) is formed in the shape of a circular rod, and its upper end is vertically inserted and fixed into the magnetic holder (20), allowing the small part (A) to be attached and detached as it moves up and down together with the magnetic holder (20).

[0031] Also, the cylinder joint (40) is bolted to the bottom of the piston (11) of the air cylinder (10).

[0032] Next, the cylinder height adjustment guide (50) is bolted to the cylinder joint (40) to adjust the operating length of the air cylinder (10), thereby adjusting the height.

[0033] And, the cylinder tube (60) is formed as a hollow cylinder to provide a space for the magnetic holder (20) and the magnetic (30) to move up and down inside, and is vertically bolted to the bottom of the cylinder joint (40).

[0034] Additionally, the tip (70) is made of synthetic resin material and is bolted to the bottom of the cylinder tube (60) to adjust the height so as to control the magnetic strength of the magnetic (30) and block the inflow of plating solution into the cylinder tube (60).

[0035] It is preferable that the tip (70) has irregularities (71) formed on its bottom surface to increase the surface area and facilitate contact with negative or positive ions, thereby improving the plating quality.

[0036] Furthermore, the mask holder (80) is press-fitted to the bottom of the tip (70) to prevent the plating solution from flowing into the cylinder tube (60) and to guide the small part (A), and a part insertion groove (81) into which the small part (A) is inserted is formed in the center of the bottom surface.

[0037] The mask holder (80) is press-fitted and fixed to the tip (70), and is provided with an O-ring (83) to block the plating solution from flowing into the cylinder tube (60) through the tip (70).

[0038] Hereinafter, the operation of a component pickup cylinder for a chrome plating system capable of preventing the inflow of plating solution according to the present invention will be described in detail with reference to the attached drawings.

[0039] First, to explain the assembly process, the cylinder joint (41) of the cylinder tube (60) is passed through the piston (11) of the air cylinder (10) to connect the cylinder joint (41) to the bottom of the air cylinder (10).

[0040] Then, a magnetic holder (20) with a magnetic (30) fixed to the piston (11) of the air cylinder (10) is attached, and a cylinder height adjustment guide (50) is bolted to the cylinder joint (40).

[0041] In this state, the magnetic holder (20) and the magnetic (30) are positioned inside the cylinder tube (60) by passing the magnetic holder (20) and the magnetic (30) through the cylinder tube (60), and then the top of the cylinder tube (60) is bolted to the cylinder height adjustment guide (50).

[0042] Next, the tip (70) is bolted to the cylinder tube (60).

[0043] Once the tip (70) is fixed, the mask holder (80) is press-fitted onto the tip (70).

[0044] Once assembly is complete, the height of the cylinder height adjustment guide (50) and the tip (70) are adjusted to control the operating length of the piston (11) and the magnetic force of the magnetic (30).

[0045] Each air cylinder (10) is assembled through the process described above, and once the assembly is complete, each air cylinder (10) is installed on the pickup plate (P) and then the pneumatic pressure is connected.

[0046] In this state, when a cassette containing a small part (A) is fed into the lower part of the pickup plate (P) for plating the small part (A), the pickup plate (P) is lowered to a position where the small part (A) is fed into the part mounting groove (81) of the mask holder (80).

[0047] Then, air pressure is supplied to each air cylinder (10), causing the piston (11) to descend within the cylinder tube (60), and the magnetic holder (20) and the magnetic (30) descend together.

[0048] As a result, a small part (A) is attached to the magnetic (30) within the part mounting groove (81) of the mask holder (80) by the magnetic force of the magnetic (30).

[0049] When a small part (A) is attached to the magnetic (30), pneumatic pressure is supplied to each air cylinder (10), causing the piston (11) to rise within the cylinder tube (60), and together the magnetic holder (20), the magnetic (30), and each small part (A) rise together.

[0050] Then, after the pickup plate (P) is advanced and lowered into the washing tank to unload the small part (A), and when the washing is completed, it is picked up, raised again, advanced, and lowered into the chrome plating tank to unload the small part (A), and when the chrome plating is completed, it is picked up, raised again, and advanced through the process of being stored in a cassette and discharged.

[0051] At this time, the O-ring (83) of the mask holder (80) blocks the plating solution of the chrome plating bath from flowing into the cylinder tube (60), and the surface area is widened by the irregularities (71) formed on the bottom surface of the tip (70), thereby making it easier for the anions or cations of the plating solution to come into contact with the small part (A), and thus improving the plating quality.

[0052] The present invention may be modified in various ways and may take various forms, and the detailed description of the invention has described only specific embodiments thereof. However, it should be understood that the present invention is not limited to the specific forms mentioned in the detailed description, but rather should be understood to include all variations, equivalents, and substitutions within the spirit and scope of the invention as defined by the appended claims.
