Hoisting equipment for electroplating automation line

Abstract

The invention provides hoisting equipment for an automatic electroplating line. The hoisting equipment for the automatic electroplating line comprises a bearing frame, two driving mechanisms and a spraying mechanism. In the working process of the hoisting equipment for the automatic electroplating line, the cleaning liquid pumping mechanism pumps cleaning liquid to the connecting pipe, and the cleaning liquid flows out of the spraying holes through the connecting pipe, the circulating cavity and the drainage cavity to spray plated parts in the two bearing rollers. In the process, the two driving mechanisms work at the same time, specifically, the driving motor drives the bearing roller to rotate through the driving wheel, the transmission belt, the driven wheel and the first rotating shaft, so that the plated part in the bearing roller is turned over. Therefore, the chemical liquid on the surface of the plating piece in the bearing roller can be fully washed away by the cleaning liquid sprayed from the spraying holes, and the cleaning effect is improved. According to the hoisting equipment for the automatic electroplating line, chemical liquid on the surface of a plated part in the bearing roller can be fully washed away by using a small amount of cleaning liquid, so that the electroplating cost is reduced.

Description

Technical Field

[0001] The present invention relates to the field of barrel plating in a full-automatic production line, and particularly to a hoisting device for an electroplating automatic line. Background Art

[0002] Electroplating production lines can be classified according to the production method into: manual electroplating production lines, semi-automatic electroplating production lines, and full-automatic electroplating production lines. According to the electroplating method, electroplating production lines can also be divided into hanging plating production lines, barrel plating production lines, continuous plating production lines, brush plating production lines, ring electroplating production lines, linear gantry electroplating production lines, plastic electroplating automatic production lines, etc. Manual electroplating production lines are suitable for electroplating precious metals, such as nickel plating, silver plating, gold plating, etc. Manual electroplating production lines have a flexible design layout, occupy a relatively small area, and can meet the electroplating processes of various parts. Semi-automatic electroplating production lines are suitable for batch production and mass production of precision electronics and small hardware parts, with high output value and good economic benefits.

[0003] However, a full-automatic electroplating production line combines relevant plating tanks, workpiece lifting and conveying devices, electrical control devices, power supply equipment, filtering equipment, detection instruments, heating and cooling devices, air stirring equipment, etc. according to certain electroplating process requirements, and automatically completes all processes required by the electroplating process through mechanical and electrical devices, with high production efficiency and stable product quality. During the rolling process of a full-automatic electroplating line, the traditional workpiece lifting and conveying device puts the barrel into chemical liquids (such as rust removal liquid, degreasing liquid), and after chemical treatment, it is successively put into the first cleaning liquid tank, the second cleaning liquid tank, and even the third cleaning liquid tank for sequential cleaning to remove the rust removal liquid on the surface of the workpiece. However, in this way, the cleaning liquids in the first cleaning liquid tank, the second cleaning liquid tank, and even the third cleaning liquid tank will be quickly contaminated, so that the cleaning liquids need to be frequently replaced, resulting in a large waste of cleaning liquid resources and an increase in electroplating costs. Summary of the Invention

[0004] Based on this, in view of the technical problems of a large waste of cleaning liquid resources and high electroplating costs during the rolling process of a traditional full-automatic electroplating line, it is necessary to provide a hoisting device for an electroplating automatic line.

[0022] Please refer to Figures 1 to 3 , the present invention provides a hoisting device 10 for an electroplating automatic line. The hoisting device 10 for the electroplating automatic line includes: a receiving frame 100, two driving mechanisms 200, and a spraying mechanism 300.

[0023] The two driving mechanisms 200 are symmetrically arranged on the receiving frame 100. In this embodiment, a connecting block 110 is arranged on the receiving frame 100, and an external driving device is drivingly connected to the receiving frame 100 through the connecting block 110. Further, the connecting block 110 and the receiving frame 100 are integrally formed.

[0024] The driving mechanism 200 includes a driving motor 210, a driving wheel 220, a transmission belt 230, a driven wheel 240, a first rotating shaft 250, a second rotating shaft 260, and a receiving roller 270. The driving motor 210 is connected to the receiving frame 100. In this embodiment, the driving motor 210 is a servo motor. In another embodiment, the driving motor 210 is a stepping motor. The driving motor 210 is drivingly connected to the driving wheel 220, and the driving wheel 220 is drivingly connected to the driven wheel 240 through the transmission belt 230. The receiving roller 270 is a hollow cylindrical structure with one end open. The driven wheel 240 is connected to the middle area of the sealed end of the receiving roller 270 through the first rotating shaft 250. In this embodiment, the first rotating shaft 250 and the receiving roller 270 are integrally formed. The driven wheel 240 is rotatably connected to the receiving frame 100 through the second rotating shaft 260.

[0025] The spraying mechanism 300 includes a connecting pipe 310, a rotating ring 320, and a spraying strip 330. One end of the connecting pipe 310 is connected to the receiving frame 100, and the other end of the connecting pipe 310 is connected to the outer wall of the rotating ring 320. In this embodiment, the connecting pipe 310 and the rotating ring 320 are integrally formed. Annular rotating grooves 301 are symmetrically formed on both sides of the rotating ring 320. The annular rotating grooves 301 are adapted to the open ends of the receiving rollers 270, and the open end of each receiving roller 270 is correspondingly inserted into an annular rotating groove 301 and rotatably connected to the rotating ring 320.

[0026] The middle area of the spray bar 330 is connected to the inner wall of the rotating ring 320. In this embodiment, the spray bar 330 and the rotating ring 320 are integrally formed. A flow cavity 302 is formed inside the rotating ring 320, a drainage cavity 303 is formed inside the spray bar 330, and a plurality of spray holes 304 are evenly formed on the side of the spray bar 330 facing away from the connecting pipe 310. The input end of the connecting pipe 310 is communicated with a cleaning liquid pumping mechanism, the output end of the connecting pipe 310 is communicated with the drainage cavity 303 through the flow cavity 302, and each spray hole 304 is communicated with the drainage cavity 303.

[0027] In order to further enhance the cleaning effect of the hoisting device 10 for the electroplating automatic line on the workpieces in the receiving drum 270, in one embodiment, the hoisting device 10 for the electroplating automatic line further includes a cleaning tank 400, which is adapted to the receiving drum 270. Arc-shaped receiving notches 401 are formed on both sides at the opening of the cleaning tank 400, and the arc-shaped receiving notches 401 are adapted to the first rotating shaft 250. The first rotating shaft 250 is inserted into the arc-shaped receiving notch 401 and rotatably connected to the cleaning tank 400. The external driving device drives each first rotating shaft 250 to be correspondingly placed in an arc-shaped receiving notch 401 through the receiving frame 100. The cleaning tank 400 can receive the cleaning liquid flowing out of the two receiving drums 270 to prevent the cleaning liquid flowing out of the two receiving drums 270 from splashing to the outside. On the other hand, when the above-mentioned hoisting device 10 for the electroplating automatic line finishes cleaning the workpieces in the two receiving drums 270, in order to further improve the cleaning effect, the external driving device drives each first rotating shaft 250 to be correspondingly placed in an arc-shaped receiving notch 401 through the receiving frame 100. The cleaning tank 400 can receive the cleaning liquid flowing out of the two receiving drums 270, and the two receiving drums 270 rotate in the cleaning tank 400 filled with the cleaning liquid to fully clean the workpieces in the two receiving drums 270. Further, in this embodiment, an ultrasonic generator 410 is provided on the cleaning tank 400 to perform ultrasonic cleaning on the receiving drum 270 in the cleaning tank 400. That is to say, the rotation of the two receiving drums 270 in the cleaning tank 400 filled with the cleaning liquid combined with ultrasonic cleaning can further improve the flushing effect on the workpieces in the two receiving drums 270.

[0028] In order to stably supply the cleaning liquid to the two receiving drums 270, in one embodiment, the above-mentioned hoisting device 10 for the electroplating automatic line further includes a cleaning liquid pumping mechanism, which includes a liquid storage tank, a pumping pump and a pumping pipe. The pumping pump is arranged in the liquid storage tank, the input end of the pumping pump is communicated with the output end of the liquid storage tank, and the output end of the pumping pump is communicated with the input end of the connecting pipe 310 through the pumping pipe. In this way, the cleaning liquid pumping mechanism can stably supply the cleaning liquid to the two receiving drums 270.

[0029] During the operation of the hoisting device 10 for the electroplating automatic line, after the external driving device drives the two receiving rollers 270 through the receiving frame 100 for chemical treatment in the chemical liquid, it is necessary to use the cleaning liquid to wash away the chemical liquid on the surface of the workpieces in the two receiving rollers 270. The cleaning liquid pumping mechanism pumps the cleaning liquid to the connecting pipe 310, and the cleaning liquid flows out from each spray hole 304 through the connecting pipe 310, the flow cavity 302, and the drainage cavity 303 to spray the workpieces in the two receiving rollers 270. During this process, the two driving mechanisms 200 work simultaneously. Specifically, the driving motor 210 drives the receiving roller 270 to rotate through the driving wheel 220, the transmission belt 230, the driven wheel 240, and the first rotating shaft 250, so that the workpieces in the receiving roller 270 are turned over. Further, the rotation directions of the two driving motors 210 driving the two receiving rollers 270 can be the same or opposite, or can be indirectly reversely rotated alternately, so that the cleaning liquid sprayed out from each spray hole 304 can fully wash away the chemical liquid on the surface of the workpieces in the receiving roller 270, improving the cleaning effect. The hoisting device 10 for the electroplating automatic line can fully wash away the chemical liquid on the surface of the workpieces in the receiving roller 270 with a small amount of cleaning liquid, reducing the electroplating cost.

[0030] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0031] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can be made, and these all belong to the protection scope of the present invention.
