Description

Technical Field

[0001] The utility model relates to the technical field of electroplating, in particular to a rotary surface treatment hanger for a precision connector. Background Art

[0002] The electroplating rack is an important tool used in the electroplating process. Its design and use have a great impact on the electroplating quality and production efficiency. The rotatable electroplating rack is a commonly used rotating surface treatment rack for electronic components.

[0003] A Chinese patent discloses a rotatable electroplating hanger (authorization announcement number CN218115650U). The utility model utilizes a first rotary drive mechanism to drive a rotating gear to rotate, so that the rotating gear drives a driven gear meshing with it to rotate synchronously, thereby realizing the rotation of the cross bar, which rotates into a designated area to work, and can effectively increase the adjustable range of the hook, facilitate hanging operation, improve the adjustability of the equipment, and facilitate use.

[0004] Since the driven gear used to drive the hook to rotate in the above-mentioned device is at the same height as the hook, and the driven gear is exposed, when the hook needs to be immersed in the electroplating liquid together with the workpiece, the driven gear is inevitably immersed in the electroplating liquid. During this process, the surface of the driven gear will also be electroplated with a coating, which will increase the transmission resistance between the driven gears. In severe cases, the driven gears may even be stuck together, making it difficult to ensure that the hook can rotate normally.

[0005] Therefore, a precision connector rotary surface treatment rack is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a precision connector rotary surface treatment rack in order to solve the above problems, thereby improving the problem that the driving structure of the rotary surface treatment rack is easily electroplated and it is difficult to ensure the normal rotation of the rack.

[0007] The utility model achieves the above-mentioned purpose through the following technical solutions. A precision connector rotary surface treatment hanger comprises: a mounting frame, wherein a mounting cavity is provided inside the mounting frame; a rotating shaft, wherein the rotating shaft is rotatably connected to the inner side of the mounting frame, and one end of the rotating shaft penetrates into the inner side of the mounting cavity; a hook, wherein the hook is fixedly connected to the surface of the rotating shaft; two sealing rings, wherein the two sealing rings are both sleeved on the surface of the rotating shaft, and the sealing rings are embedded and installed on the inner side of the mounting frame; an electric rotating mechanism, wherein the electric rotating mechanism is installed inside the mounting cavity, and the top of the electric rotating mechanism penetrates into the outer side of the mounting frame, and the electric rotating mechanism One end of the structure is fixedly connected to the rotating shaft; there are two anti-adhesion mechanisms, and the two anti-adhesion mechanisms are symmetrically fixedly connected to the surface of the mounting frame, and the surfaces of the mounting frame, the rotating shaft and the sealing ring are all in contact with the anti-adhesion mechanism. The driving structure of the electric rotating mechanism is arranged inside the mounting cavity and the sealing ring is used to flexibly seal the gap between the rotating shaft and the mounting frame. Even if the hook and the workpiece are immersed in the electroplating liquid, the sealing ring can block the electroplating liquid outside the mounting frame, which enables the worm and the worm wheel to operate in a dry and clean environment, so as to ensure that the electric rotating mechanism can rotate the rotating shaft normally, and the rotating shaft drives the workpiece to rotate normally through the hook.

[0008] Preferably, the anti-adhesion mechanism includes a mounting base fixedly connected to the inner side of the mounting frame, one end of the mounting base is slidably connected to a scraper, the surfaces of the mounting frame, the rotating shaft and the sealing ring are all in contact with the scraper, and the anti-adhesion mechanism can scrape off the coating around the contact portion of the rotating shaft and the sealing ring while the rotating shaft rotates, which can not only reduce the rotation burden of the rotating shaft, but also reduce the probability of the rotating shaft getting stuck due to obstruction of the coating, thereby reducing the subsequent maintenance burden of the staff.

[0009] Preferably, one end of the mounting base is fixedly connected to a sliding rod, and the surface of the sliding rod is slidably connected to a sliding sleeve fixedly connected to the scraper. A spring that is always in a compressed state is arranged between the sliding rod and the sliding sleeve, which can increase the connection tightness between the scraper and the rotating shaft to improve the scraping effect of the scraper.

[0010] Preferably, the vertical cross-section of the scraper is in the shape of a right triangle, and the included angle between the slide rod and the slide sleeve and the horizontal plane is forty-five degrees, which can increase the contact area between the scraper and the rotating shaft, and further improve the cleaning effect on the rotating shaft.

[0011] Preferably, the vertical cross-sectional shapes of the connecting parts of the slide rod and the slide sleeve are both matched rectangles, which can prevent the scraper from rotating to ensure that the scraper can be stably fitted with the rotating shaft.

[0012] Preferably, a rubber bellows is fixedly connected between the mounting base and the sliding sleeve, and the connection between the sliding rod and the sliding sleeve is arranged on the inner side of the rubber bellows, which can avoid the probability of the electroplating liquid penetrating into the interior of the sliding sleeve, so that the sliding rod and the sliding sleeve operate in a dry and clean environment.

[0013] Preferably, the electric rotating mechanism includes a servo motor, the output shaft of the servo motor extends through the interior of the mounting cavity, a worm is fixedly connected to the surface of the servo motor, and the surface of the worm is meshingly connected to a worm wheel fixedly connected to the rotating shaft. The electric rotating mechanism can rotate the hook and the workpiece to a corresponding angle, and adopts a design of a worm driving a worm wheel. When the worm does not rotate, the worm can be confined to this angle by the worm, which effectively reduces the probability of angle deviation of the workpiece, thereby improving the stability coefficient of the workpiece after rotation.

[0014] The beneficial effects of the utility model are:

[0015] 1. The driving structure of the electric rotating mechanism is arranged inside the mounting cavity and a sealing ring is used to seal the gap between the rotating shaft and the mounting frame. Even if the hook and the workpiece are immersed in the electroplating liquid, the sealing ring can block the electroplating liquid outside the mounting frame, which enables the worm and the worm wheel to operate in a dry and clean environment, thereby ensuring that the electric rotating mechanism can rotate the rotating shaft normally, and the rotating shaft drives the workpiece to rotate normally through the hook;

[0016] 2. The anti-adhesion mechanism can scrape off the coating around the contact area between the shaft and the sealing ring while the shaft is rotating, which can not only reduce the rotation burden of the shaft, but also reduce the probability of the shaft getting stuck due to coating blockage, thereby reducing the subsequent maintenance burden of the staff.

The surfaces of the mounting frame 1, the rotating shaft 2 and the sealing ring 4 are all in contact with the anti-adhesion mechanism 6. Before use, the mounting frame 1 needs to be connected to an external lifting machinery in advance, such as a lifting gantry, which is currently a common machine used for lifting electroplating hangers. The specific model and power supply method can be selected according to actual needs, which will not be elaborated here.

[0024] like Figure 2 and Figure 3 As shown, the electric rotating mechanism 5 includes a servo motor 51, the output shaft of the servo motor 51 passes through the interior of the mounting cavity 11, a worm 52 is fixedly connected to the surface of the servo motor 51, and the surface of the worm 52 is meshingly connected to a worm wheel 53 fixedly connected to the rotating shaft 2; when the staff needs to rotate the workpiece, the staff only needs to manually control the servo motor 51 to drive the worm 52 to rotate in the corresponding direction, the worm 52 drives the worm wheel 53 to rotate, the worm wheel 53 drives the rotating shaft 2 to rotate, the rotating shaft 2 drives the hook 3 to rotate, and the hook 3 drives the workpiece to rotate until the workpiece is rotated to the corresponding angle.
