Description

Technical Field

[0001] This utility model relates to the technical field of electroplating equipment, and in particular to a fully automatic gantry electroplating equipment. Background Technology

[0002] Electroplating is the process of depositing a thin layer of another metal or alloy onto the surface of certain metals using the principle of electrolysis. It is a process that uses electrolysis to attach a metal film to the surface of metal or other material parts, thereby preventing metal oxidation, improving wear resistance, conductivity, reflectivity, corrosion resistance, and enhancing aesthetics.

[0003] Chinese patent document CN220318000U discloses a gantry-type electroplating equipment, including an electroplating tank body. A gantry frame body is mounted on top of the electroplating tank body, and a suspension frame is movably mounted on the bottom of the gantry frame body. An adjustment mechanism is located on top of the electroplating tank body, comprising an electric slide rail, a slider, a motor, a support plate, an electric push rod, and a turntable. In operation, the operator first suspends the products sequentially on the hooks. Then, the electric slide rail is activated, and the slider moves the gantry frame body forward until it reaches directly above the electroplating tank body. At this point, the electric push rod extends, causing the products on the suspension frame to move downwards and fully immerse themselves in the electroplating solution. To ensure more uniform electroplating, the motor drives the support plate and the turntable at the bottom to rotate, allowing the electroplating solution to adhere more fully to the products. Finally, the reciprocating extension and retraction of the electric push rod repeatedly immerses the products in the electroplating solution, thus ensuring a better electroplating effect.

[0004] However, existing gantry-type electroplating equipment suffers from a problem: the electroplated parts tend to shake during movement through the plating tank. This not only causes friction between the parts but also removes the already plated metal layer, reducing the uniformity and adhesion of the plating layer and affecting the overall performance and appearance quality of the electroplated parts. Furthermore, ensuring a uniform plating layer within the electroplating tank is a crucial step in the electroplating process. Uneven plating can lead to localized corrosion or wear during use, shortening the lifespan of the electroplated parts. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. The purpose of the present invention is to provide a fully automatic gantry electroplating equipment to solve the problems mentioned in the background art.

[0006] To address the aforementioned problems, this utility model provides a fully automatic gantry electroplating device, comprising an electroplating tank, support frames on both sides of the electroplating tank, a gantry frame on the support frames, a slide rail on the gantry frame, an electric hoist slidably connected to the slide rail, a chain wound and fixedly wound around the drive end of the electric hoist, a fixing ring sleeved on the chain, an auxiliary chain fixedly connected to the outer ring of the fixing ring, a clamping frame at the bottom of the chain, and a counterweight rod at the end of the chain near the clamping frame.

[0007] The fully automatic gantry electroplating equipment provided by this utility model also has the following technical features:

[0008] Furthermore, the support frame is provided with positioning holes, and the bottom of the gantry frame is provided with holes that match the positioning holes. The positioning holes and holes are fixed together by positioning pins.

[0009] Furthermore, a mounting frame is fixedly connected to the side of the electric hoist, and a pulley is provided at the top of the mounting frame. The electric hoist is slidably connected to the slide rail through the pulley on the mounting frame.

[0010] Furthermore, the chain is provided with engagement holes, and the inner ring of the fixing ring is provided with hooks, and the fixing ring is engaged with the engagement holes on the chain through the hooks.

[0011] Furthermore, hooks are fixedly connected to the bottom of both the chain and the auxiliary chain, and both the chain and the auxiliary chain are adapted to the buckles at the top of the clamping frame via the hooks.

[0012] Furthermore, the clamping frame is fixedly connected to a positioning threaded hole, and a suspension rod is threadedly connected to the positioning threaded hole, with a groove provided on the suspension rod.

[0013] Furthermore, one end of the suspension rod is provided with a thread that matches the positioning threaded hole, and the other end of the suspension rod is fixedly connected to a baffle.

[0014] Furthermore, the width and depth of the electroplating tank are adapted to the clamping frame and the suspension rod on the clamping frame.

[0015] This utility model has the following beneficial effects: First, by setting positioning holes on the support frame and matching holes at the bottom of the gantry frame, and using positioning pins for fixing, the stability of the gantry frame is ensured, thereby reducing shaking during the electroplating process. Simultaneously, the mounting bracket and pulleys on the side of the electric hoist allow the electric hoist to move smoothly along the slide rail, further reducing friction on the electroplated parts during movement. The counterweight balances the chain system, reducing additional friction caused by uneven weight distribution of the electroplated parts. These improvements work together to effectively protect the electroplated layer and prevent damage caused by friction. Second, by using hooks to match the buckles at the top of the clamping frame with the chain and auxiliary chain, stable clamping of the electroplated parts during the electroplating process is ensured, avoiding uneven electroplating thickness caused by improper clamping.
