Detailed implementation manners

[0025] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present invention and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0026] Such as Figure 1-7A mobile conductive end of a horizontal super-long rod hard chrome electroplating device shown in the figure comprises a guide rail (not shown), a moving frame 1, a brush assembly 2, a drive assembly 3 and a conduction assembly 4. Two guide rails are installed in parallel above the plating tank, the moving frame 1 is slidably installed on the guide rails, the brush assembly 2 is installed on the lower side of the moving frame 1, the drive assembly 3 and the conduction assembly 4 are both installed on the moving frame, the drive assembly 3 is used to drive the moving frame 1 to reciprocate along the guide rail, and the conduction assembly 4 is used to realize the on / off of the brush assembly 4.

[0027] like Figure 1 , Figure 2 , Figure 4 As shown, the mobile frame 1 includes a frame body 11, which is a rectangular structure welded from steel sections. Four pairs of running wheels 12, two pairs of transverse guide wheels 13 and two pairs of longitudinal guide wheels 14 are symmetrically installed on both sides of the lower end surface of the frame body 11. The frame body 11 is movably mounted on the guide rail through the four pairs of running wheels 12. The two pairs of transverse guide wheels 13 are mounted at both ends of the frame body 11, and the transverse guide wheels 13 abut against the outer side surface of the guide rail to limit the transverse position of the frame body 11. Two pairs of longitudinal guide wheels 14 are mounted on the lower side of both ends of the frame body 11, and the longitudinal guide wheels 14 abut against the lower end surface of the guide rail to limit the longitudinal position of the frame body 11. The cooperation of the transverse guide wheels 13 and the longitudinal guide wheels 14 prevents the frame body 11 from detaching from the guide rail during operation.

[0028] like Figure 1 , Figure 2 , Figure 4 As shown, the driving assembly 3 includes a driving motor 31, a driving shaft 32 and a driving gear 33. The driving shaft 32 is rotatably mounted on the lower end surface of the frame body 11 through two bearing seats. The driving motor 31 is a worm gear reduction motor with a brake. The driving motor 31 is fixedly mounted on the lower side of the frame body 11, and the output shaft of the driving motor 31 is fixedly connected to the driving shaft 32. Two driving gears 33 are respectively fixed at both ends of the driving shaft 32. The driving gear 33 is connected to the running wheel 12 through a gear box. The rotation of the driving motor 31 drives the driving shaft 32 to rotate, and then drives the running wheel 12 to rotate through the driving gear 33, so that the frame body 11 moves along the guide rail.

[0029] like Figure 1-Figure 3As shown in the figure, two sets of locking components 5 are symmetrically installed on the lower end face of the frame body 11. The locking component 5 includes a second telescopic member 51 and a locking block 52, and the locking block 52 is fixed to the telescopic end of the second telescopic member 51. Among them, the second telescopic member 51 can be an electric push rod, a cylinder or a hydraulic cylinder. When the frame body 11 moves, the second telescopic member 51 drives the locking block 52 to separate from the guide rail to avoid affecting the movement of the frame body 11. When the frame body 11 moves to the required position, the second telescopic member 51 drives the locking block 52 to abut against the guide rail to prevent the frame body 11 from displacing and ensure the accuracy of the position of the brush assembly 2. Preferably, a brake pad is also attached to the surface of the locking block 52 close to the guide rail to increase the friction between the locking component 5 and the guide rail.

[0030] As Figure 1 , Figure 2 , Figure 4 , Figure 5 shown, the brush assembly 2 includes two main brackets 21. The two main brackets 21 are vertically installed on the lower end face of the frame body 11 through insulating pads, and a conductive shaft 22 is rotatably installed between the lower ends of the two main brackets 21 through bearings. Two connecting rods 23 are installed in parallel between the upper halves of the two main brackets 21. Each connecting rod 23 is provided with an L-shaped copper row 24. Three copper foil flexible connections 25 are installed on the horizontal plane of the copper row 24, and a plurality of brush units 26 are installed on the vertical plane of the copper row 24. The plurality of brush units 26 are symmetrically distributed on both sides of the conductive shaft 22.

[0031] As Figure 1 , Figure 2 , Figure 4 , Figure 5 shown, the brush unit 26 includes a fixing plate 261, a movable plate 262 and a brush head 263. The fixing plate 261 and the movable plate 262 are both made of insulating materials. The fixing plate 261 is fixedly installed on the side of the main bracket 21 through two cross bars 27. The movable plate 262 is installed on one side of the fixing plate 261 close to the conductive shaft 22 through two first telescopic members 264. The brush head 263 is installed on one side of the movable plate 262 close to the conductive shaft 22. A first compression spring 265 is sleeved on the first telescopic member 264 to press the brush head 263 against the conductive shaft 22. Among them, the side of the brush head 263 close to the guide shaft 22 is an arc surface matching the conductive shaft 22 to increase the contact area between the brush head 263 and the conductive shaft 22 and improve the conductive effect.

[0032] As Figure 5 shown, the upper end of the brush head 263 is electrically connected to the copper row 24 through a conductive sheet 266. The copper row 24 passes current to the conductive shaft 22 through the conductive sheet 266 and the brush head 263. Preferably, a protective cover 27 is installed outside the brush assembly 2 to ensure the use safety of the equipment and personnel.

[0033] AsFigure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 As shown in Figure 7 , the conduction component 4 is installed on the lower end face of the moving frame 1. The conduction component 4 includes a fixed seat 41, and the fixed seat 41 is installed on the lower side of the frame body 11 parallel to the connecting rod 23. At both ends of the upper end face of the fixed seat 41, a first telescopic member 42 is respectively installed. The first telescopic member 42 can be a cylinder, an electric push rod or a hydraulic cylinder, and the first telescopic member 42 is vertically installed on the fixed seat 41. The telescopic end of the first telescopic member 42 passes through the fixed seat 41 and is connected with an insulating plate 43. The lower end face of the insulating plate 43 is installed with a conductive plate 46 through a second telescopic rod 44. A second compression spring 45 is sleeved on the second telescopic rod 44, and the second compression spring 45 is located between the insulating plate 43 and the conductive plate 46. The other end of the copper foil flexible connection 25 is fixedly installed on the upper side of the conductive plate 46. The lower end of the conductive plate 46 is installed with an input copper row 47, and the input copper row 47 is connected to an external power supply, and the input copper row 47 extends along the length direction of the guide rail.

[0034] During the electroplating operation, the first telescopic member 42 drives the insulating plate 43 to move downwards, so that the conductive plate 46 is connected with the input copper row 47, and the current flows through the input copper row 47, the conductive plate 46, the copper foil flexible connection 25, the copper row 24, the conductive sheet 266, and the electric brush head 263 into the conductive shaft 22. The arrangement of the second telescopic rod 44 and the second compression spring 45 can not only play a buffering role, extend the service life of the conduction component 4, but also improve the tightness of the connection between the conductive plate 46 and the input copper row 47.

[0035] During non-electroplating, the first telescopic member 42 drives the insulating plate 43 to move upwards, so that the conductive plate 46 is separated from the input copper row 47. At this time, the brush assembly 2 is not charged, ensuring the safety of workers.

[0036] The technical solution provided by the embodiment of the present application has at least the following technical effects or advantages:

[0037] By driving the brush assembly to move through the driving mechanism, the position of the brush assembly can be conveniently adjusted according to the product size, which is simple and easy to operate and saves labor; the gear structure is adopted to drive the moving frame to move, ensuring the accuracy of the moving position and the stability of the emergency braking, and improving the safety of the equipment.
