Description

Technical Field

[0001] The utility model relates to the technical field of electroplating processing, in particular to an electroplating feeding mechanism. Background Art

[0002] Electroplating is a metal finishing technique that uses the principle of electrolysis to deposit a thin layer of metal on a metal or other conductive surface. The process involves the target workpiece as the cathode and the opposing plating metal as the anode or in dissolved form in a tank, both of which are immersed in an electrolyte containing dissolved metal salts. Under the action of a power source, the metal ions on the anode migrate through the solution to the surface of the workpiece at the cathode and are deposited to form a uniform metal layer. Electroplating aims to improve the appearance (such as gloss and color), corrosion resistance, wear resistance, hardness and conductivity of the workpiece. The electroplating process includes multiple steps, usually starting with pretreatment (cleaning, oxide removal, degreasing, etc.) to ensure good adhesion of the coating. Post-treatment such as cleaning, drying and polishing may be performed after electroplating. A variety of metals are used for electroplating, including copper, nickel, chromium, gold, silver, zinc and lead. This technology is widely used in industries such as automotive, electronics, aerospace, jewelry, hardware, etc., both as a protective coating and for decorative purposes.

[0003] When electroplating workpieces, they are often loaded onto fixtures and electroplated together in batches. However, fixtures loaded with a large number of workpieces are heavy and difficult for operators to carry directly. Therefore, transport racks are created for transportation. However, the height of the transport racks themselves is high. Although operators do not need to carry them horizontally, it is difficult to lift the fixtures frequently.

[0004] Therefore, an electroplating feeding mechanism is proposed to solve or alleviate the above problems. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes an electroplating feeding mechanism.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The electroplating feeding mechanism includes a plurality of vertical frames, a top frame fixedly connected to the vertical frames, and a rotating component arranged on the top frame. The rotating component is provided with a plurality of installation points, and the installation points are provided with connecting hooks that can be raised and lowered and positioned.

[0008] Preferably, the rotary component is fixedly connected to a plurality of vertically arranged connecting vertical pipes, the connecting vertical pipes form installation points, and a servo motor is fixedly connected to the connecting vertical pipe. The output shaft of the servo motor passes through the connecting vertical pipe and is fixedly connected to a wire-taking roller, and a connecting rope fixedly connected to a connecting hook is wound around the wire-taking roller.

[0009] Preferably, the connecting rope is made of UHMWPE fiber.

[0010] Preferably, the servo motor includes an electromagnetic brake disposed therein, and the electromagnetic brake controls the output shaft of the servo motor to stop rotating.

[0011] Preferably, it also includes a control circuit, which includes a controller, a wireless generator, a wireless receiver 1, and a wireless receiver 2. The controller is coupled to the wireless generator, the wireless generator is communicatively connected to the wireless receiver 1 and the wireless receiver 2, the wireless receiver 1 is coupled to the servo motor, and the wireless receiver 2 is coupled to the electromagnetic brake.

[0012] Preferably, the slewing assembly includes a driving motor fixedly connected to the top frame, a driving sprocket fixedly connected to the output shaft of the driving motor, a driven sprocket rotatably connected to the top frame, and a chain transmission connecting the driving sprocket and the driven sprocket, and the connecting vertical pipe is fixedly connected to the chain.

[0013] Preferably, a friction sleeve which is sleeved on the outside is fixedly connected to the crossbar portion of the connecting hook.

[0014] Preferably, the friction sleeve is made of rubber.

[0015] The utility model has the following beneficial effects:

[0016] The utility model simplifies the process of mounting a heavy-load fixture. The operator manually grasps the crossbar of the connecting hook with a friction sleeve made of rubber material, applies force to separate the connecting hook from the connecting vertical pipe, releases the connecting rope, and lowers the connecting hook to an appropriate height. Then, the hole on the fixture allows the connecting hook to pass through easily, and the fixture with the workpiece is hung up with only a small amount of force. The rubber friction sleeve effectively increases the friction between the fixture and the hook to prevent it from falling off.

[0017] Next, a signal is sent to wireless receiver 1 to command the servo motor to rotate the take-up roller and tighten the connecting rope, which further lifts the mounted fixture until the connecting hook contacts the connecting vertical pipe. To prevent reverse rotation due to the weight of the fixture and workpiece, the controller again sends a signal to wireless receiver 2 to activate the electromagnetic brake, braking the servo motor to ensure stable suspension.

[0018] Subsequently, the drive motor starts, and drives the vertical pipe to rotate through a series of sprockets and chains to smoothly complete the continuous loading steps, ensuring that the entire handling process is both efficient and stable, greatly saving the operator's physical strength, and significantly improving work efficiency and safety.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Electroplating feeding mechanism, such as Figure 1 As shown, it includes a plurality of vertical frames 1, a top frame 3 fixedly connected to the plurality of vertical frames 1, and a swivel assembly arranged on the top frame 3, wherein a plurality of mounting points are arranged on the swivel assembly, and a connecting hook 11 which can be raised and lowered and positioned is arranged on the mounting points, as shown in FIG. Figure 3 As shown, the connecting hook 11 is L-shaped, and a friction sleeve 12 sleeved on the outside is fixedly connected to the crossbar portion of the connecting hook 11, and the friction sleeve 12 is made of rubber.

[0028] like Figure 2 and 3As shown, the rotary assembly includes a driving motor 4 fixedly connected to the top frame 3, a driving sprocket 5 fixedly connected to the output shaft of the driving motor 4, a driven sprocket 6 rotatably connected to the top frame 3, and a chain 7 transmission-connecting the driving sprocket 5 and the driven sprocket 6.

[0029] like Figure 4 and 5 As shown, a plurality of vertically arranged connecting vertical pipes 8 are fixedly connected to the rotary assembly. Specifically, the connecting vertical pipe 8 is fixedly connected to the chain 7, the connecting vertical pipe 8 forms an installation point, and a servo motor 9 is fixedly connected to the connecting vertical pipe 8. The output shaft of the servo motor 9 passes through the connecting vertical pipe 8 and is fixedly connected to a take-up roller. A connecting rope 10 made of UHMWPE fiber and fixedly connected to a connecting hook 11 is wound around the take-up roller.

[0030] like Figure 6 As shown, the servo motor 9 includes an electromagnetic brake 17 arranged therein, and the electromagnetic brake 17 controls the output shaft of the servo motor 9 to stop rotating. The present solution also includes a control circuit, and the control circuit includes a controller 13, a wireless generator 14, a wireless receiver 15, and a wireless receiver 2 16. The controller 13 is coupled to the wireless generator 14, and the wireless generator 14 is communicatively connected with the wireless receiver 15 and the wireless receiver 2 16. The wireless receiver 15 is coupled to the servo motor 9, and the wireless receiver 2 16 is coupled to the electromagnetic brake 17. The controller 13 is a 51 series single chip microcomputer.

[0031] The utility model is used when the operator needs to use the clamp to hang a large number of workpieces, and the operator only needs to manually hold the crossbar of the connecting hook 11, that is, contact it with the friction sleeve 12, and then the operator manually applies a force to drive the output shaft in the servo motor 9 to rotate, and then drive the take-up roller to rotate, and pay out the connecting rope 10, so that the connecting hook 11 can be separated from the connecting vertical pipe 8 and go to a lower horizontal position, and then the connecting hook 11 only needs to pass through the hole on the clamp to make the clamp be hung on the connecting hook 11, and at this time the operator only needs to expend less effort to complete the action of lifting the clamp loaded with a large number of workpieces, and it does not need to rise to a high level. The setting of the friction sleeve 12 is that when the clamp is hung on the connecting hook 11, the friction between the clamp and the crossbar of the connecting hook 11 can be increased by the friction sleeve 12 made of rubber material, so that the two are not easily separated, and then it is triggered by the controller 13. , and sends a signal to the wireless receiver 15 through the wireless generator 14, and uses the wireless receiver 15 to apply a command to the servo motor 9, so that the servo motor 9 is powered on to drive its output shaft to rotate in the positive direction, and then drives the take-up roller to rotate, so as to complete the take-up of the connecting rope 10, and then the connecting hook 11 and the fixture loaded with the workpiece are lifted until the vertical rod of the connecting hook 11 can contact the bottom end of the connecting vertical pipe 8, and then the controller 13 sends a signal to the wireless receiver 16 through the wireless generator 14. After issuing a command, the wireless receiver 16 controls the electromagnetic brake 17 to be energized after receiving the command, so that it brakes the output shaft in the servo motor 9 to prevent it from rotating, and the take-up roller and the output shaft will not be deflected in the opposite direction due to the heavy weight of the clamp and the workpiece, ensuring that the clamp can be hung securely and stably for loading, and then the drive motor 4 is started to continuously drive the active sprocket 5, chain 7, and driven sprocket 6 to complete the rotation of several connecting vertical pipes 8, thereby realizing continuous loading.
