Description

Technical Field

[0001] The present application relates to the technical field of electroplating equipment, and in particular to an electroplating rack with easy-to-adjust hooks. Background Art

[0002] Electroplating is a process that forms a uniform metal or alloy coating on the surface of a workpiece through electrolytic deposition. It is widely used in the automotive, electronics, aerospace and other fields to improve the corrosion resistance, conductivity and aesthetics of the workpiece. During the electroplating process, the electroplating rack serves as a key carrier connecting the power supply and the workpiece. If the rack design is unreasonable, it may lead to uneven coating distribution, poor contact with the workpiece, or even a short circuit, which directly affects production efficiency and product yield. Therefore, the flexibility and reliability of the rack are key links in optimizing the electroplating process.

[0003] At present, the hangers commonly used in the electroplating industry are mostly fixed designs, mainly including a main rod, a hook and a lifting rod. These hangers are usually equipped with several fixed hooks on both sides of the main rod for hanging the workpieces to be electroplated. Although this design is simple and practical, it has many inconveniences in actual operation. In particular, when processing workpieces of different sizes and shapes, the position and angle of the hooks cannot be flexibly adjusted, resulting in low work efficiency and easy damage to the workpieces.

[0004] In the related art, the existing hanger racks mainly include: 1. Fixed hook design: Most traditional electroplating racks use a fixed hook design, that is, the position and angle of the hook are pre-set and cannot be adjusted at will. The advantages are simple structure and low cost; the disadvantages are poor flexibility and unsuitable for the needs of various workpieces. Adjustable hook design: Some improved designs allow the hook to move within a certain range, but still cannot freely adjust the angle. This method improves some flexibility, but it is still not comprehensive enough. 2. Rotating hook design: A few designs use rotating hooks, but their load-bearing strength is poor and they are prone to deformation or falling off under heavy loads.

[0005] In summary, the technical defects of existing hangers mainly include: 1. The hook position and angle are fixed, which cannot meet the electroplating requirements of different types of workpieces; 2. Even if some designs allow a certain degree of adjustment, the load-bearing strength of the hook is often sacrificed, resulting in reduced safety and stability; 3. The overall structure is complex, maintenance is difficult, and production costs are increased. Summary of the Invention

[0006] In order to solve the problems that the hook position and angle of the existing hanger rack are fixed, which cannot meet the electroplating needs of different types of workpieces, and the hook has low bearing strength, resulting in reduced safety and stability. At the same time, the overall structure is complex, maintenance is difficult, and production costs increase, the present application provides an electroplating hanger rack with easy adjustment of the hook.

At the same time, the cam curve in the spacing adjustment mechanism drives multiple groups of hooks to move synchronously and equidistantly to achieve uniform adjustment of the spacing. Compared with traditional split adjustment methods such as threaded sleeves and slide rails, this design avoids the tedious operation of point-by-point adjustment and significantly improves compatibility with workpieces of different sizes.

[0013] Optionally, the width of the internal cavity of the first limiting seat is smaller than that of the second limiting seat, and the width of the limiting toothed disc is equal to the internal cavity of the second limiting seat.

[0014] By adopting the above technical solution and utilizing cavities of different widths, the limiting toothed disc can be clamped between the first limiting seat and the second limiting seat.

[0022] By adopting the above technical solution and utilizing the structure in which the protrusions engage with the toothed notches, the belt is prevented from slipping during linkage.

[0023] Optionally, a clamping block is fixed on the bottom of the sliding seat, a clamping seat is slidably clamped on the clamping block, and the support rod is fixed on the clamping seat.

[0025] Optionally, a screw hole is provided through one end of the sliding seat, the inner thread of the screw hole is matched with a screw rod, and one end of the screw rod is rotatably connected to the clamping seat.

[0026] By adopting the above technical solution, the threaded linkage of the screw rod is utilized to drive the clamping seat to move on the clamping block, thereby achieving precise adjustment of the overall position of the suspension mechanism.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. Utilizing the engagement / disengagement mechanism between the limited toothed disc and the tooth groove in the suspension mechanism, the hook angle can be quickly adjusted with a single operation, and locking by engagement ensures stability. This structure simplifies the adjustment process while avoiding the loss of positioning accuracy caused by frequent disassembly. The gear meshing creates a rigid connection, effectively suppressing shaking in dynamic electroplating environments compared to spring clamping or friction positioning methods, improving the hook's shock resistance and anti-drift capabilities. 2. The cam curve in the spacing adjustment mechanism drives the synchronous and equidistant movement of multiple hooks, achieving uniform spacing adjustment. Compared to traditional separate adjustment methods such as threaded sleeves and slide rails, this design avoids the tedious operation of point-by-point adjustment, reduces the number of connection nodes, and avoids the risk of deformation or fracture due to localized stress concentration, thus ensuring load-bearing strength under high-load conditions. 3. The cam and gear mechanism are integrated into a closed frame, reducing exposed parts, lowering the risk of electrolyte corrosion, and extending service life. The gears are directly driven by the knob, eliminating the need for special adjustment tools. Compared with traditional design structures, this greatly reduces maintenance difficulty and downtime. The present invention uses mechanical linkage and a rigid locking mechanism to improve adjustment flexibility while taking into account structural strength and operational convenience. It solves the conflict between traditional hangers in multi-workpiece adaptation, long-term stability, and economy, and can be widely used in high-demand electroplating scenarios in precision electronics, aerospace and other fields.

[0048] The implementation principle of the electroplating rack with easy hook adjustment in the embodiment of the present application is as follows: first, the angle of the hook 42 is adjusted according to actual processing requirements. During adjustment, the push rod 47 is pressed to move the limit toothed disc 46 into the second limit seat 44. At this time, the second limit seat 44 rotates in the first limit seat 43 until the hook 42 reaches an appropriate angle. Then, the push rod 47 is released, and the limit toothed disc 46 is reset under the elastic force of the reset member 48, and is clamped between the first limit seat 43 and the second limit seat 44 to lock them together. Then, the active disk 56 is driven to rotate by the servo motor 55, and the driven disk 54 is driven to rotate by the belt 57, so that the adjusting rod 51 can be synchronously linked. At this time, the protrusion 53 slides in the slide groove 52, and the slide groove 52 is used to limit and guide the protrusion, so that the sliding seat 3 slides on the guide rod 2 until multiple sliding seats 3 are synchronously adjusted to the appropriate spacing.
