Definitions

  • the invention relates to a galvanizing magazine for coating components according to the preamble of claim 1.
  • the electroplating process is a widespread process if the application of protective layers to surfaces of large and small parts is intended to improve their material properties.
  • the process control before, during and after the coating and the devices used for this purpose are essential for the economic viability of such processes.
  • drum-like electroplating frames are often used, which are filled with the components to be coated in bulk and inserted into the electroplating bath with the horizontal drum axis. As a result, large series of components can be surface coated economically.
  • the object of the invention is to provide a generic electroplating magazine for coating components, with which components can be coated in large numbers with coating quality that is as reproducible as possible.
  • the electroplating magazine according to the invention has the advantage that the regular or uniform spacing of the component receptacles in the circumferential and axial directions on the outer circumference of the drum-shaped electroplating magazine allows a defined spacing from the anode of the electroplating bath to be maintained. On the one hand, this enables a reproducible and controllable coating quality of the components in a large series run, on the other hand, the electroplating magazine is accessible to automated assembly and dismantling through the defined spaced arrangement of the component receptacles on the electrodes, so that individual quality control of the components can be carried out economically.
  • the external component receptacles also ensure that the electroplating magazine can be used in the process processes that do not directly belong to the electroplating process, such as rinsing, roughening and drying, without the need to implement the components. Further advantageous embodiments of the invention result from the features of claims 2 to 20.
  • the electroplating magazine 1 has a coaxial, circular distributor disk 4 made of copper, which in turn is connected to a likewise disk-shaped holder 6 via an electrically insulating and axially extending central body 5.
  • Ten rod-shaped electrodes 3 are arranged in a revolving manner around the central body 5 in the space between the distributor disk 4 which is perpendicular to the central body 5 and the holder 6 which is likewise perpendicular to the central body 5.
  • the electrodes 3 are each plug-connected at their two ends via base parts 7 formed on the electrode side to the holder 6 in a position-centering manner or fastened in an electrically conductive manner to the distributor disk 4 via screw connections 8.
  • the screw connections 8, screws 9 and the internal thread 10 on the electrode side are coated with gold.
  • the distributor disc 4 has circumferentially spaced and radially extending grooves 11 on the electrode side at an angle of 36 °.
  • the necks 12 of the electrodes 3 receiving the internal thread 10 each protrude transversely into these grooves 11, so that after loosening the screw connections 8 when the electrodes 3 are tilted around their base parts 7, the necks 12 move radially out of the grooves 11 and thus the electrodes 3 to the electroplating magazine 1 can be removed.
  • the electroplating magazine 1 can be loaded and dismounted with electrodes 3 with little effort. Only when assembling the For an optimal electrical connection, electrodes 3 must ensure a tight screw connection 8.
  • a toothed ring 13 is formed on the outer circumference of the distributor disk for rotating the electroplating magazine 1. If the electrodes 3 are to be loaded or dismounted by a device (not shown further), the component receptacles 14 provided for fixing the small components 2 on the electrodes 3 can be brought into an exact loading or dismounting position by rotating the electroplating magazine 1 about its longitudinal axis L. to be brought. In addition, the electroplating magazine 1 can be rotated during drying, rinsing or coating to increase the effectiveness.
  • An electrical cable is provided as an additional electrical line connection 15 between the electrode 3 and the distributor plate 4, which ensures the current supply even when the screw connections 8 are in poor contact.
  • the line connection 15 is shown representative of all other electrodes only on one electrode 3 '.
  • a soldering lug 16 establishes the secure connection between the electrode 3 'and the electrical cable.
  • a shaft 17 is formed on the distributor disk 4 beyond the electrodes 3 and has a contact surface 19 that widens conically to the shaft end 18.
  • the contact surface 19 serves on the one hand as a power connection and as a holding force-transmitting element of the plating magazine 1.
  • the plating magazine 1 can be used during the coating process, during rinsing and drying instead of via the rotating ring 13 drive over the shaft 17.
  • the large-area contact surface 19 ensures a low-resistance current transfer during the coating process.
  • the electrodes 3 essentially each consist of an electrically conductive electrode rod 21, an aperture 22 having the component receptacles 14 and a rod-shaped permanent magnet 23 located within the electrode rod 21.
  • the cover 22 has a row of boreholes serving as component receptacles 14, into which the small components 2 are inserted and permanent magnets 23 extending along the electrode rod 21 can be held on the electrode 3 with electrical contact.
  • the row of boreholes R is aligned parallel to the longitudinal axis L of the magazine, which accommodates the accessibility during the automatic loading and unloading.
  • the component receptacles 14 are evenly spaced from one another, thereby eliminating electrical or magnetic disturbances which adversely affect the coating.
  • the borehole axes A of the component receptacles 14 are essentially perpendicular to the longitudinal axis L of the magazine, which likewise promotes reproducibly good layer formation and facilitates automatic loading and unloading.
  • these each have 24 pin holes as positioning means.
  • the material of the central body 5 and the holder 6 is made of an electrochemically resistant plastic.
  • the electrode rods 21 are provided with a protective layer, and the cover 22 is made of an electrochemically resistant plastic.
  • bracket 6 For a trouble-free function of the electroplating magazine 1 during transportation and movement during the process steps as well as during loading and unloading, a bracket 6 is used. Axially concentric running surface 25 and a coaxial centering bore 26, which is provided on the holder 6 on the other side of the central body 5.
