Description

Technical Field

[0001] The utility model relates to the technical field of electroplating, in particular to a roller plating device for preventing workpieces from being sucked in. Background Art

[0002] In the prior art, generally smaller workpieces are electroplated by barrel plating. Barrel plating is to place the workpiece in a barrel, immerse it in the electroplating solution, and rotate the barrel to achieve tumbling electroplating of the internal workpiece. However, due to the large number of workpieces, especially for some small thin sheet-like workpieces, such as gaskets, etc., during the tumbling process in the barrel, it is easy to cause two or more workpieces to be attracted and unable to be separated, resulting in the inability to plate the contacting surfaces during the electroplating process, affecting the electroplating effect and quality, and a high defective rate. Utility Model Content

[0003] In order to solve the above technical deficiencies, the utility model provides a roller plating device for preventing workpieces from being sucked together, which can promote the rapid flow of electroplating liquid in the drum during the roller plating process, so as to facilitate separation of the workpieces and improve the uniformity and reliability of electroplating.

[0004] The utility model discloses a roller plating device for preventing workpieces from being sucked together, comprising an electroplating pool and a roller, wherein shaft seats opening upward are arranged on opposite sides of the electroplating pool, and short shafts are arranged at both ends of the roller, wherein the short shaft is used to be mounted in the shaft seat, and when the short shaft is located in the shaft seat, the roller is partially immersed in the electroplating liquid in the electroplating pool, a driven gear is arranged on the short shaft, and a power mechanism is arranged outside the electroplating pool, wherein the output shaft of the power mechanism extends to the side of the shaft seat, and a driving gear is arranged on the output shaft, and the driving gear is meshed with the driven gear on the short shaft on the same side, and the roller is provided with a plurality of driven gears. A feed gate is provided, and a plurality of groups of through holes are arranged at intervals along the axial direction on the drum, each group of through holes has a plurality of through holes, and are arranged at intervals on the same circumference of the drum; a circulation pump is provided below the electroplating pool, an input pipe of the circulation pump extends to the lower end inside the electroplating pool, an output pipe of the circulation pump extends to the inside of the electroplating pool and is horizontally placed below the drum, a circumference of the output pipe in the electroplating pool is parallel to the circumference of the drum, an end of the output pipe in the electroplating pool is closed, and a plurality of vertically upward nozzles are arranged at intervals on the output pipe in the electroplating pool, and the position of each nozzle corresponds to the position of each group of through holes.

[0005] A pressure regulating valve is arranged on the output pipe between the circulation pump and the nozzle to adjust the spray pressure of the nozzle.

[0006] The through hole is a long hole, and the length direction of the long hole is arranged along the circumference of the drum.

[0007] The sum of the lengths of each group of through holes is 1 / 3-2 / 3 of the length of the circumference of the drum.

[0008] Driven gears are arranged on the short shafts on both sides of the drum.

[0009] The utility model provides a roller plating device for preventing workpieces from being sucked together. A circulating pump is used to spray the electroplating liquid upward from a nozzle, and the electroplating liquid enters the interior through the through hole of the roller, so as to make the electroplating liquid in the roller more fluid. When the workpieces are tumbling, the workpieces can be better separated, so as to improve the uniformity of electroplating and the electroplating quality of the workpieces. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0011] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0012] Embodiment 1:

[0013] like Figure 1 As shown, the utility model discloses a roller plating device for preventing workpieces from being sucked in, comprising an electroplating pool 1 and a roller 3, wherein shaft seats 2 opening upward are arranged on opposite sides of the electroplating pool 1, and short shafts 6 are arranged at both ends of the roller 3, wherein the short shaft 6 is used to be mounted in the shaft seat 2, and when the short shaft 6 is located in the shaft seat 2, the roller 3 is partially immersed in the electroplating solution in the electroplating pool 1, and a driven gear 7 is arranged on the short shaft 6, and a power mechanism 8 is arranged outside the electroplating pool 1, wherein an output shaft 9 of the power mechanism 8 extends to the side of the shaft seat 2, and a driving gear 10 is arranged on the output shaft 9, and the driving gear 10 is meshed with the driven gear 7 on the short shaft 6 on the same side, and a drive mechanism 8 is arranged on the roller 3. There is a feed gate 4, and a plurality of groups of through holes 5 are arranged at intervals along the axial direction on the drum 3, and each group of through holes 5 has a plurality of through holes 5 and are arranged at intervals on the same circumference of the drum 3; a circulation pump 11 is arranged below the electroplating pool 1, and an inlet pipe 12 of the circulation pump 11 extends to the lower end inside the electroplating pool 1, and an output pipe 13 of the circulation pump 11 extends to the inside of the electroplating pool 1 and is horizontally placed below the drum 3, and the circumference of the output pipe 13 in the electroplating pool 1 is parallel to the circumference of the drum 3, and the end of the output pipe 13 in the electroplating pool 1 is closed, and a plurality of vertically upward nozzles 14 are arranged at intervals on the output pipe 13 in the electroplating pool 1, and the position of each nozzle 14 corresponds to the position of each group of through holes 5.

[0014] An axle seat 2 is provided on the electroplating tank 1, and the short shafts 6 at both ends of the roller 3 are mounted in the axle seat 2. At this time, the driven gear 7 on the short shaft 6 is meshed with the driving gear 10 on the output shaft 9 of the power mechanism 8, and the power mechanism 8 drives the roller 3 to rotate. The power mechanism 8 can be a combination of a motor and a reduction box. Part of the roller 3 is immersed in the electroplating solution of the electroplating tank 1, and the electroplating solution can enter the inside of the roller 3 from the through hole 5. In order to allow the roller 3 to be immersed more in the electroplating tank 1, the axle seat 2 can be set on the side wall inside the electroplating tank 1, and the height of the roller 3 can be reduced as a whole. The circulation pump 11 delivers the electroplating solution in the electroplating tank 1 to the output pipe 13, and sprays it upward from the nozzle 14. During the upward spraying process, when the drum 3 rotates to the point where the through hole 5 corresponds to the nozzle 14, the sprayed electroplating solution enters the drum 3 from the through hole 5, causing the electroplating solution in the drum 3 to flow quickly and generate a mixed state, thereby causing an impact on the tumbling workpiece, making the workpiece more dispersed and less likely to be attracted, thereby improving the electroplating effect. Moreover, when the electroplating solution level in the drum 3 is high, the electroplating solution sprayed from the nozzle 14 will not exceed the electroplating solution level in the drum 3, and will not cause the electroplating solution to splash.

[0015] A pressure regulating valve 15 is provided on the output pipe 13 between the circulation pump 11 and the nozzle 14, for adjusting the spray pressure of the nozzle 14. The regulating valve 15 is used to adjust the spray pressure of the nozzle 14, so that the electroplating liquid sprayed by the nozzle 14 produces a stable stirring effect in the drum 3, and does not cause splashing of the electroplating liquid, and has high stability and reliability.

[0016] The through hole 5 is a long hole, and the length direction of the long hole is arranged along the circumference of the drum 3. The through hole 5 is a long hole, so that the electroplating liquid sprayed by the nozzle 14 enters the drum 3 for a longer time during the rotation of the drum 3, so the stirring time in the drum 3 is longer, thereby improving the dispersion effect on the workpiece and improving the electroplating effect.

[0017] The sum of the lengths of each group of through holes 5 is 1 / 3-2 / 3 of the length of the circumference of the drum 3. The length of the through holes 5 can be selected according to actual needs, such as the sum of the lengths of the through holes 5 is 1 / 2 of the circumference of the drum 3. Of course, all the through holes 5 can be of equal length or unequal length.

[0018] The short shafts 6 on both sides of the drum 3 are provided with driven gears 7. If the driven gears 7 are provided on both short shafts 6, there is no need to specially distinguish the direction when the drum 3 is mounted on the shaft seat 2, so as to improve the convenience of operation. Of course, this solution requires that the driven gears 7 at both ends of the drum 3 and the through holes 5 on the drum 3 are symmetrically arranged in the middle position of the axis of the drum 3 to ensure that the driven gears 7 at both ends of the drum 3 cooperate with the driving gear 10, and the through holes 5 on the drum 3 correspond to the nozzle 14.
