Description

Technical Field

[0001] This utility model relates to the field of electroplating technology, specifically to an automatic electroplating equipment for hardware parts. Background Technology

[0002] Hardware is a tool made of metal materials, covering categories such as locks, handles, door and window accessories, and bathroom accessories, and is widely used in building decoration, home equipment and industrial production.

[0003] Automatic electroplating equipment for hardware parts refers to equipment used to achieve fully automatic electroplating treatment of metal parts in the electroplating process. Its main purpose is to deposit a metal coating on the surface of hardware parts to improve their corrosion resistance, aesthetics, conductivity or wear resistance. Existing automatic electroplating equipment for hardware parts is divided into various types according to their different electroplating methods, such as electroplating tanks, barrel plating machines, rack plating lines, and continuous electroplating lines.

[0004] However, when using automatic electroplating equipment for metal parts in electroplating tanks, the parts to be plated are completely immersed in the electroplating solution inside the electroplating tank. When the electroplating process is completed, the parts to be plated are removed from the electroplating solution and moved to the next processing area. During the movement, the electroplating solution adhering to the outer surface of the parts will drip onto the movement path, resulting in waste of plating solution and cross-contamination. Therefore, this does not meet the existing requirements. To address this, we propose an automatic electroplating equipment for metal parts. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The metal electroplating tank body 1 (model VudAnpGS), stepper motor 4 (model DM542), and small vibrator 16 (model ZFB) mentioned in this utility model can be obtained from the market or through private customization.

[0023] Please see Figures 1 to 4This utility model provides an embodiment of an automatic electroplating device for hardware parts, comprising a hardware electroplating tank body 1. Multiple stepper motors 4 are fixedly installed on the lower side inside the hardware electroplating tank body 1. The output shafts of the stepper motors 4 are connected to a transmission shaft 5 via couplings. A first bevel gear 6 is fixedly sleeved on both sides of the outer surface of the transmission shaft 5. The first bevel gear 6 meshes with a second bevel gear 7. A threaded rod shaft 8 is connected to the axis of the second bevel gear 7. A lifting threaded rod 9 is fixedly connected to the upper end face of the threaded rod shaft 8. The outer surface of the lifting threaded rod 9... The lower side is fitted with an internal threaded sleeve 10 that is slidably connected to the main body 1 of the metal electroplating tank via a threaded structure. A vibrator mounting bracket 15 is fixedly provided on one side of the outer surface of the internal threaded sleeve 10. A small vibrator 16 is fixedly installed on the inner side of the vibrator mounting bracket 15. A support base sleeve 11 is attached to the upper end face of the small vibrator 16. A slider 12 is slidably installed on the support base sleeve 11 facing the nearest internal threaded sleeve 10. The slider 12 is fixed to the internal threaded sleeve 10 facing the nearest internal threaded sleeve 10, and a spring 13 is connected to the lower end face of the slider 12.

[0024] Metal rods 14 are inserted inside the support base sleeve 11. A plated part hanging bracket 2 is fixed on the upper end face of two corresponding metal rods 14, which is located above the main body of the metal plated part electroplating tank 1. A smart control panel 3 is fixedly installed on the upper side of the rear end face of the main body of the metal plated part electroplating tank 1. The main body of the metal plated part electroplating tank 1, the stepper motor 4 and the small vibrator 16 are all electrically connected to the smart control panel 3. The equipment can be controlled through the smart control panel 3.

[0025] The outer side of the top end of the metal rod 14 is provided with a circular positioning through hole on the outer surface of the metal electroplating tank body 1. The position of the circular positioning through hole corresponds to the support base sleeve 11 located below it, and the cross-sectional shape of the inner wall of the circular positioning through hole corresponds to the cross-sectional shape of the inner wall of the support base sleeve 11. The outer surface of the metal rod 14 fits against the inner wall of the support base sleeve 11, and the metal rod 14 and the inner wall of the support base sleeve 11 are slidably connected. When the equipment needs to be used, the hook with the metal parts on the outer surface is hung on the outer surface of the electroplating part hanging frame 2. Then, the two metal rods 14 fixed to the lower end face of the electroplating part hanging frame 2 are respectively aligned with the two circular positioning through holes located on the outer surface of the metal electroplating tank body 1 and inserted. As the metal rods 14 are gradually inserted, the metal rods 14 will eventually be inserted into the interior of the support base sleeve 11 located below the circular positioning through hole.

[0026] As the metal rod 14 moves toward the support base sleeve 11, the electroplated part hanging frame 2 will gradually move downwards. As the electroplated part hanging frame 2 moves downwards, the hooks hanging on the outer surface of the electroplated part hanging frame 2 and the hardware on the outer surface of the hooks will enter the electroplating solution inside the hardware electroplating bath body 1 for electroplating treatment.

[0027] After the electroplating of the hardware is completed, the stepper motor 4 corresponding to its position is started. The stepper motor 4 drives the transmission shaft 5 connected to it and the two first bevel gears 6 fixedly sleeved on the outer surface of the transmission shaft 5 to rotate. The rotating first bevel gears 6 can drive the second bevel gear 7 meshing with it and the threaded rod shaft 8 connected to the axis of the second bevel gear 7 to rotate synchronously. When the threaded rod shaft 8 rotates, the lifting threaded rod 9 fixed to the upper end face of the threaded rod shaft 8 and the internal threaded sleeve 10 installed on the outer surface of the lifting threaded rod 9 through the threaded structure will move up and down accordingly. When the internal threaded sleeve 10 moves upward, the support base sleeve 11, which is connected to it via the slider 12 and spring 13, will also move upward. During this upward movement, the metal rod 14 inside the support base sleeve 11 and the electroplated part suspension bracket 2 fixed to the upper surface of the metal rod 14 will gradually move upward as well. As the electroplated part suspension bracket 2 rises, the electroplated part, having undergone electroplating, will be smoothly lifted from the electroplating solution to above the liquid surface. Once the hardware part is completely removed from the liquid surface, the intelligent control panel 3 will activate the small vibrator 16.

[0028] A spring 13 is connected to the lower end face of the slider 12, which is slidably installed on the outer surface of the support base sleeve 11 and fixed to the outer surface of the inner thread sleeve 10. Through the sliding connection structure between the support base sleeve 11 and the slider 12 and the spring 13 connected to the lower end face of the slider 12, when the small vibrator 16 is started, the support base sleeve 11 that is in contact with it will generate high-frequency micro-amplitude vibration. This vibration will eventually be transmitted to the metal parts that are indirectly connected to it and moved to the top of the electroplating solution to complete the electroplating, thereby shaking off the residual electroplating solution adhering to the outer surface of the metal parts.

[0029] The above technical solution can automatically clean up the electroplating solution adsorbed on the outer surface of the electroplated part, thereby preventing the electroplating solution originally adsorbed on the outer surface of the electroplated part from spilling onto the movement path when the electroplated part is moved in the future, thus causing waste of the plating solution and cross-contamination.

[0030] After the small vibrator 16 has been running for five minutes, the small vibrator 16 is turned off through the intelligent control panel 3. Then, the electroplated part hanging frame 2 is lifted directly to move the hardware on the electroplated part hanging frame 2 to the next processing area.

[0031] The front end of the transmission shaft 5 is located inside the outer shell of the metal electroplating tank body 1, and the transmission shaft 5 located inside the outer shell of the metal electroplating tank body 1 is connected to the metal electroplating tank body 1 by a roller bearing; the roller bearing structure between the transmission shaft 5 and the metal electroplating tank body 1 can ensure the stability of the rotating transmission shaft 5.

[0032] A rubber protective pad is fixed to the lower end face of the support base sleeve 11, and the position of the rubber protective pad corresponds to the position of the small vibrator 16; the rubber protective pad can protect the support base sleeve 11 that is in direct contact with the small vibrator 16.

[0033] A protective cover plate is provided behind the stepper motor 4 on the outer surface of the metal plating tank body 1, and the metal plating tank body 1 and the protective cover plate are fixed together by screws; the protective cover plate can seal and protect the stepper motor 4, and when the stepper motor 4 fails, the protective cover plate can be removed.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
