Description

Technical Field

[0001] This utility model relates to the field of electroplating production line technology, and in particular to a fully automatic loading and unloading device for electroplating production lines. Background Technology

[0002] Electroplating is a surface treatment technology that uses the principle of electrolysis to attach a metal layer to the surface of parts. It is widely used in industries such as electronics, automotive, hardware, and aerospace to achieve purposes such as corrosion resistance, wear resistance, gloss enhancement, and improved conductivity. A typical electroplating production line consists of a series of electroplating tanks with different functions (such as degreasing tanks, pickling tanks, copper plating tanks, nickel plating tanks, chromium plating tanks, etc.) and auxiliary tanks such as washing tanks and drying tanks, forming a continuous production line. In this production process, the parts to be processed need to be immersed and cleaned sequentially in different tanks according to a strict process flow, and then precisely and efficiently transferred between the tanks. Therefore, achieving automated loading, unloading, and transfer of parts between various stations on the electroplating production line is the core link to ensure its efficient and stable operation, and also the key to improving the automation level of the production line.

[0003] Currently, while the loading and unloading methods of electroplating production lines have gradually evolved from relying entirely on manual operation in the early days, many problems still need to be solved. Many traditional production lines still adopt a semi-automated mode, where operators manually hang parts on flybars or racks, and then overhead cranes transport them to designated tanks. This method is extremely labor-intensive, and prolonged exposure to chemical solutions poses health risks. Furthermore, the instability of manual operation easily leads to inconsistent production cycles and damage from impacts, severely impacting production efficiency and product consistency. While some production lines using automated overhead cranes reduce the burden on manpower, their large mechanical structures, fixed operating paths, and low flexibility make them unsuitable for the flexible production needs of multi-variety, small-batch production, and their positioning accuracy is also relatively low.

[0004] Therefore, it is necessary to design a fully automated loading and unloading device for the electroplating production line to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the problems that still exist in electroplating production lines, such as high labor intensity, high health risks, and unstable manual operation affecting efficiency and consistency, although the development of electroplating production lines has been from manual to semi-automatic and automatic, automated cranes have the disadvantages of being bulky, lacking flexibility, being difficult to adapt to multi-variety small-batch production, and having low positioning accuracy, this utility model provides a fully automatic loading and unloading device for electroplating production lines.

[0006] The technical solution is as follows: a fully automatic loading and unloading device for an electroplating production line, including a frame, guide rails, moving wheels, rotating shafts, fixed seats, a sliding frame, a first reduction motor, side pulleys, side frames, guide rods, sliders, connecting rods, mounting seats, crossbars, lifting components, loading and unloading components, and sensing components. The frame is installed on the ground, and guide rails are symmetrically installed inside the frame. Each guide rail has a sliding groove, and two moving wheels are rolled within each of the two sliding grooves. A rotating shaft rotatably connects the two moving wheels on one side, while a fixed seat rotatably connects one side of each of the two moving wheels on the other side. The two fixed seats are symmetrically distributed. One side of the sliding frame is fixedly connected to the two fixed seats, and the other side is rotatably connected to the rotating shaft, which is located inside the sliding frame. The first geared motor is fixedly connected to the main body, and the output end of the first geared motor is fixedly connected to the rotating shaft. Side pulleys are symmetrically and rotatably connected to both sides of the bottom of the sliding frame. The two side pulleys on the same side abut against the inner side of the corresponding guide rail. The angle formed by each side pulley and the corresponding moving wheel is a right angle. The side frame is composed of two upright frames and support rods. The upper part of the two upright frames is fixedly connected to the sliding frame on one side. Vertically distributed guide rods are fixedly connected inside the two upright frames. A slider is slidably connected to each guide rod. A connecting rod is fixedly connected to the left side of the two upright frames. A mounting base is fixedly connected to the bottom of the two connecting rods. A crossbar is fixedly connected through the two mounting bases. A lifting component is provided inside the sliding frame. Loading and unloading components are provided on the crossbar. A sensing component is provided at the front of the side frame.

[0007] To further clarify, both sliders slide within their respective vertical frames.

[0008] To further explain, the lifting assembly includes bearings, a connecting shaft, a second reduction motor, a winding wheel, a traction belt, a hanging ring, and a fastening block. Top rods are fixedly installed on both sides of the top of the sliding frame, and bearings are fixedly connected to the bottom of each of the two top rods. A horizontally distributed connecting shaft passes through and is fixed in the inner rings of the two bearings. A second reduction motor is fixedly connected to the front of the sliding frame, and the output end of the second reduction motor is fixedly connected to the front of the connecting shaft. Winding wheels are fixedly fitted on both sides of the connecting shaft, and the two winding wheels are symmetrically distributed. A traction belt is wound around the outside of each of the two winding wheels. Hanging rings are fixedly connected to the top of each of the two mounting seats. One end of each traction belt passes through the corresponding hanging ring between the hanging ring and the mounting seat, and the passing ends of both traction belts are flipped to fit against their own sides and fixedly connected by the fastening block.

[0009] To further explain, the loading and unloading assembly includes a V-groove plate, a locking block, an abutment block, an electroplating device, a support recess, a transfer block, and a hanging rod. Two V-groove plates are fixedly connected to both sides of the crossbar. Each locking block has two horizontal columns on one side, and each horizontal column is placed inside the V-groove plate. The two locking blocks are symmetrically distributed. An abutment block is fixedly connected to the bottom of each locking block. The two abutment blocks have an inverted triangular structure. The electroplating device is installed on the ground and is located inside the frame. Multiple support recesses are fixedly connected to both sides of the top of the electroplating device. Each support recess has a V-groove on its top suitable for the corresponding abutment block. A transfer block is fixedly connected to one side of the lower part of each of the two abutment blocks. A hanging rod is fixedly connected between the two transfer blocks.

[0010] To further explain, the sensing component includes a mounting block, a sensor, a controller, and a signal receiving block. Two mounting blocks are fixedly connected to the left side of one side of the frame. The two mounting blocks are vertically distributed. Sensors are fixedly connected to both sides of the two mounting blocks. A controller is fixedly connected to the front of the support rod. A signal receiving block is fixedly connected to the left side of the controller. The signal receiving block is electrically connected to the controller. All four sensors are electrically connected to the signal receiving block.

[0011] To further explain, the distance between the two sensors on the same side is equal to the thickness of the connecting rod located on the front side.

[0012] To further clarify, both the first and second geared motors are electrically connected to the controller.

[0013] The beneficial effects of this utility model are as follows: 1. By adopting a right-angle support structure composed of side pulleys and moving wheels, this utility model greatly enhances the torsional rigidity and overall stability of the sliding frame during high-speed heavy-duty movement, effectively preventing the risk of overturning and jamming during operation; at the same time, through the lifting mechanism composed of a second reduction motor, winding wheel, traction belt and guide rod, and combined with the closed-loop control system formed by sensors and controllers, the lifting process of the hanging rod is made extremely stable and highly precise, ensuring that the parts can be accurately immersed in and removed from the tank liquid, thus improving the process quality.

[0014] 2. This utility model, through the setting of guide rails, moving wheels, a first reduction motor and a sliding frame linked with them, realizes fully automatic horizontal conveying of the hanging rod between various workstations of the electroplating production line. It effectively replaces the traditional transfer mode that relies on manual operation or rigid cranes. It not only significantly reduces the labor intensity and health risks of operators, but also ensures the consistency and continuity of production rhythm through precise program control, thereby greatly improving the overall operation efficiency and product processing consistency.

[0015] 3. This utility model adopts a hanging method that combines a V-shaped groove plate with a horizontal column, which makes the installation and disassembly of the hanging rod simple and quick, and enhances the adaptability of the device to hanging rods of different specifications; the overall structure is reasonably laid out, and the transmission and lifting mechanism is efficient and reliable, which helps to reduce the manufacturing and maintenance costs of the equipment while realizing automation functions.

Detailed Implementation

[0025] Example: Fully automatic loading and unloading device for electroplating production line, such as Figures 1-8As shown, the system includes a frame 1, guide rails 2, casters 21, a rotating shaft 22, a fixed seat 23, a sliding frame 24, a first reduction motor 25, a side frame 35, a guide rod 36, a slider 37, a connecting rod 38, a mounting base 39, a crossbar 4, a lifting assembly, a loading / unloading assembly, and a sensing assembly. The frame 1 is mounted on the ground with screws. The upper side of the frame 1 is symmetrically connected to the guide rails 2 by welding. Each guide rail 2 has a sliding groove, and each groove contains two rolling casters 21. A rotating shaft 22 is rotatably connected between the two casters 21 on the left side. On the other side, a fixed seat 23 is rotatably connected to the two casters 21 that are close to each other. The two fixed seats 23 are symmetrically distributed front to back. The right side of the sliding frame 24 is fixedly connected to the two fixed seats 23, and its left side is rotatably connected to the rotating shaft 22. The rotating shaft 22 is located on the sliding frame. Inside the left side of the sliding frame 24, a first geared motor 25 is installed by screws. The output end of the first geared motor 25 is connected to the rotating shaft 22 by a coupling. The side frame 35 consists of two upright frames and support rods. The upper part of the two upright frames is close to each other and is installed together with the sliding frame 24 by screws. The interior of each upright frame is connected by vertically distributed guide rods 36 by welding. Each guide rod 36 is slidably connected to a slider 37. The two sliders 37 slide inside the corresponding upright frame. The lower left side of each upright frame is installed by screws with connecting rods 38. The bottom of each connecting rod 38 is connected by welding with mounting bases 39. A crossbar 4 is installed through the interior of the two mounting bases 39 by screws. The lower side of the sliding frame 24 is provided with a lifting component. The crossbar 4 is provided with loading and unloading components. The front side of the side frame 35 is provided with a sensing component.

[0026] like Figure 3 As shown, it also includes side pulleys 26. The bottom of the sliding frame 24 is symmetrically connected to the side pulleys 26 on both the front and rear sides. The two side pulleys 26 on the same side of the front and rear abut against the inner side of the corresponding guide rail 2. The angle formed by each side pulley 26 and the corresponding moving wheel 21 is a right angle.

[0027] like Figure 4As shown, the lifting assembly includes bearings 3, connecting shafts 31, a second reduction motor 32, winding wheels 33, traction belts 34, hanging rings 310, and fastening blocks 311. The top of the sliding frame 24 is connected to top rods on both the front and rear sides by welding. Bearings 3 are installed at the bottom center of each of the two top rods by screws. A horizontally distributed connecting shaft 31 passes through and is fixed in the inner rings of the two bearings 3. The front end of the sliding frame 24 is fixedly connected to the second reduction motor 32. The output end of the second reduction motor 32 is connected to the front end of the connecting shaft 31 by a coupling. Winding wheels 33 are connected to both the front and rear sides of the connecting shaft 31 by welding. The two winding wheels 33 are symmetrically distributed front and rear. Traction belts 34 are wound around the outer surfaces of both winding wheels 33. Hanging rings 310 are connected to the top center of each of the two mounting seats 39 by welding. One end of each traction belt 34 extends downwards, passing between the corresponding hanging ring 310 and the mounting seat 39. The passing ends of both traction belts 34 are flipped and fitted against their own sides, and are installed by screws through fastening blocks 311.

[0028] like Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the loading and unloading assembly includes a V-shaped groove plate 41, a locking block 42, an abutment block 43, an electroplating device 11, a support recess 44, a transition block 45, and a hanging rod 46. The front and rear sides of the crossbar 4 are connected to two V-shaped groove plates 41 by welding. Each locking block 42 has two horizontal columns on one side, and each horizontal column is placed inside the V-shaped groove plate 41. The two locking blocks 42 are symmetrically distributed front and back. The bottom sides of the two locking blocks 42 are connected to the abutment blocks 43 by welding. The two abutment blocks 43 have an inverted triangular structure. The electroplating device 11 is installed on the ground with screws. The electroplating device 11 is located inside the lower side of the frame 1. The front and rear sides of the top of the electroplating device 11 are equipped with multiple support recesses 44 by screws. The top of each support recess 44 has a V-shaped groove suitable for the corresponding abutment block 43. The lower sides of the two abutment blocks 43 that are close to each other are equipped with transition blocks 45 by screws. The hanging rod 46 is installed between the two transition blocks 45 by screws.

[0029] like Figure 8As shown, the sensing component includes a mounting block 5, a sensor 51, a controller 52, and a signal receiving block 53. Two mounting blocks 5 are welded to the left side of the front frame. The two mounting blocks 5 are vertically distributed. Sensors 51 are installed on both the upper and lower sides of the two mounting blocks 5 with screws. The distance between the two sensors 51 on the same side is equal to the thickness of the connecting rod 38 on the front side. The controller 52 is installed in the middle of the front side of the support rod with screws. The first reduction motor 25 and the second reduction motor 32 are both electrically connected to the controller 52. The signal receiving block 53 is installed on the left side of the controller 52 with screws. The signal receiving block 53 is electrically connected to the controller 52. All four sensors 51 are electrically connected to the signal receiving block 53.

[0030] When this device is needed for fully automated loading and unloading, the operator first places the hanging rod carrying the parts to be electroplated onto the loading and unloading assembly via the locking blocks 42 at both ends. Specifically, the two horizontal bars on each locking block 42 are placed into the V-groove plates 41 on the corresponding mounting bases 39. The V-groove plates 41 are designed to effectively limit and support the horizontal bars, thereby stably suspending the entire flybar (composed of two adapter blocks 45, two abutment blocks 43, and two locking blocks 42) under the two mounting bases 39, completing the initial preparation for loading.

[0031] Subsequently, the controller 52 issues a command to start the first reduction motor 25. The output of the first reduction motor 25 drives the rotating shaft 22 to rotate, thereby moving the sliding frame 24 along the guide rail 2. The sliding frame 24 rolls forward in the sliding groove via the moving wheels 21, realizing horizontal feeding motion. During this process, the side pulleys 26 always maintain contact with the inner surface of the guide rail 2, forming a stable right-angle support structure with the moving wheels 21. This greatly enhances the torsional rigidity and running stability of the sliding frame 24 under high-speed movement and load conditions, effectively preventing overturning and jamming.

[0032] When the sliding frame 24, carrying the flybar, moves horizontally to directly above the target electroplating bath, the horizontal movement stops. Then, the lifting assembly begins operation. The controller 52 instructs the second reduction motor 32 to operate, and the output of the second reduction motor 32 drives the connecting shaft 31 and the winding wheel 33 to rotate synchronously. The winding wheel 33 rotates and releases the traction belt 34 wound around it. Since the bottom end of the traction belt 34 is fixed to itself by the fastening block 311, a closed-loop traction structure is formed. Under the action of gravity, the entire loading and unloading assembly, the crossbar 4, the V-groove plate 41, and the flybar suspended therefrom, connected by the connecting rod 38, will slide smoothly downwards along the guide rod 36. Guided and limited by the slider 37, a vertical descent is achieved, precisely immersing the flybar and its suspended parts into the electroplating bath solution.

[0033] After the electroplating process is completed, the controller 52 commands the second geared motor 32 to rotate in the opposite direction, and the winding wheel 33 begins to retract the traction belt 34. Under the lifting action of the traction belt 34, the entire loading and unloading assembly is smoothly lifted upward along the guide rod 36, removing the electroplated parts from the bath and raising them to a predetermined height. Afterward, the first geared motor 25 starts again, driving the sliding frame 24 to move horizontally to the next station or return to the initial position.

[0034] Precise positioning throughout the entire operation is achieved by sensing components. The upper sensor 51 detects the upper limit position of the connecting rod 38. When triggered, the controller 52 instructs the second geared motor 32 to stop, causing the hanging rod 46 to stop at a preset transfer height. The lower sensor 51 detects the lower limit position of the connecting rod 38 to determine whether the hanging rod 46 has descended to the processing depth within the electroplating tank. When triggered, the controller 52 instructs the second geared motor 32 to stop and starts process timing. When the connecting rod 38 triggers different sensors 51 during lifting and lowering, signals are transmitted to the controller 52 via the signal receiving block 53. The controller 52 processes these signals to precisely control the start, stop, direction, and speed of the first geared motor 25 and the second geared motor 32, ultimately achieving precise closed-loop control of the flybar's horizontal movement and lifting height, ensuring high precision and high reliability in the fully automated loading and unloading process.
