[0002] Electroplating line trolleys are a type of rail transport equipment specifically used in electroplating workshops to move workpieces; they are also called electric flatcars or rail flatcars. They are simple in structure, easy to operate, can carry heavy loads, and reduce pollution, making them particularly suitable for use in electroplating production lines, machine manufacturing, and metallurgical plants.

[0003] In the industrial equipment and manufacturing field, VCP most commonly stands for Vertical Continuous Plating, which is one of the core process technologies in PCB manufacturing. VCP is an automated process that suspends the printed circuit board vertically and continuously passes it through an electroplating bath to achieve uniform deposition of metal layers (such as copper, nickel, and gold).

[0004] However, traditional electroplating transfer equipment suffers from problems such as low movement accuracy, easy leakage and pollution of waste liquid, and insufficient operational safety, making it difficult to adapt to the continuous operation requirements of automated production lines. In vertical continuous electroplating (VCP), the coating uniformity is poor. Summary of the Invention

Detailed Implementation

Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0021] To address the issues of low movement precision, easy leakage and pollution of waste liquid, and difficulty in adapting to the continuous operation requirements of automated production lines in existing electroplating transfer equipment, as well as the poor coating uniformity during vertical continuous electroplating (VCP), the following will combine the attached... Figures 1 to 3 The present invention provides a detailed description of an electroplating line trolley according to an embodiment of the invention.

[0022] Please see Figure 1 and Figure 3 , Figure 1 This is a first-view three-dimensional structural diagram of the electroplating line trolley according to an embodiment of the present invention; Figure 2 yes Figure 1 Enlarged view of point A; Figure 3 This is a second-view three-dimensional structural diagram of the electroplating line trolley described in an embodiment of the present invention.

[0023] An electroplating line trolley, comprising: Support 1 consists of two vertically symmetrically arranged brackets. The top beam 2 is fixedly connected to the top of the two supports 1, and the top beam 2 is equipped with a first drive motor 21 and a linkage bearing 22. A first mounting bracket 3 is disposed on the longitudinal side of the bracket 1, and a first track 31 is provided on the longitudinal side of the first mounting bracket 3. The second mounting bracket 4 is horizontally arranged between the first brackets 1. The second mounting bracket 4 is provided with a second drive motor 41. The output end of the second drive motor 41 is provided with a first drive gear 411. The first drive gear 411 is connected to a bearing 412. The other end of the bearing 412 is provided with a first driven gear 413. The horizontal moving device 5 includes a rack 51 and a first crossbeam 52. The rack 51 is connected to the first crossbeam 52. A wheel 53 is provided at the bottom of the rack 51. The wheel 53 can move freely on the first track 31. The rack 51 meshes with the first drive gear 411. The horizontal moving device 5 can move back and forth on the first crossbeam 52. The lifting device 6 is located on the inner side of the two supports 1 and is connected to the linkage bearing 22.

[0024] Specifically, the electroplating line trolley serves as the workpiece transport carrier on the production line, connecting the entire electroplating process. The trolley runs throughout the entire electroplating process, providing an integrated workpiece transport solution for automated electroplating production lines, offering precise transfer and stable lifting. It possesses the following functions: ① cross-station transfer; ② stable lifting operation; ③ load-bearing capacity and safety protection, adapting to the needs of industrial production; ④ efficient waste liquid recovery.

[0025] The support frame 1 and the top beam 2 form an integrated support structure. Support frame 1 consists of two high-strength metal supports arranged vertically and symmetrically, forming the support frame of the electroplating line trolley and providing an installation foundation for various functional components, ensuring the stability of the overall structure. Anti-slip pads or fixing bolts can be installed at the bottom of support frame 1 as needed to further improve placement stability. The top beam 2 uses a metal profile matching support frame 1 and is fixed to the top of the two supports 1 by welding or bolting, serving to horizontally reinforce the support and distribute the upper load, preventing the support from shifting during operation. The top beam 2, arranged in parallel or integrated design, provides an installation position for the second drive motor 41, improving the redundancy of the drive system and the reliability of equipment operation.

[0026] The second drive motor 41 is mounted on the second mounting frame 4. The wheels 53 at the bottom of the horizontal moving device 5 can roll smoothly along the first track 31 of the first mounting frame 3. The second drive motor 41 drives the horizontal moving device 5 to move back and forth along the first track 31, realizing the precise displacement of the horizontal moving device (including the waste liquid collection component on it), so that the workpiece can be transferred laterally between different electroplating stations (such as electroplating tank, cleaning tank, drying area). With the stepless speed regulation characteristics of the servo motor, the moving speed can be adjusted according to the station distance, taking into account both transfer efficiency and stability, and avoiding the workpiece shaking or waste liquid splashing during the movement.

[0027] The power for the lifting action comes from the first drive motor 21 and the linkage bearing 22. Power start: After the control system receives the lifting command, it starts the first drive motor 21 (forward rotation achieves descent, reverse rotation achieves ascent). The first drive motor 21 outputs rotational power, which drives the linkage bearing 22 to rotate, and drives the transmission belt to wind around the linkage bearing 22, thereby realizing the lifting of the workpiece.

[0028] Transmission coordination: The first driving gear 411 and the symmetrically arranged first driven gear 413 form a clamping group, and synchronous rotation is achieved through the bearing 412.

[0029] Working process: After receiving the horizontal movement command from the control system, it starts and outputs rotational power. The rotational power is converted into linear motion through the meshing of its own first drive gear 411 with the rack 51 of the horizontal movement device 5. The bearing 412 drives the first driven gear 413 to rotate synchronously, ensuring transmission balance and avoiding slippage caused by excessive force on a single gear.

[0030] Beneficial effects: The electroplating line trolley, through its high-strength structural design and multiple safety mechanisms, ensures the stability and safety of workpieces during transfer and lifting. Through the coordination of the second drive motor 41 and the horizontal moving device 5, it achieves efficient switching of workpieces between different process stations, improves transfer positioning accuracy, and ensures the uniformity of VCP plating. The improved electroplating line trolley adopts high-precision track guidance and servo drive control, which can achieve precise docking and stable transfer of workpieces between the tanks of each VCP process. It avoids the problem of inconsistent immersion depth of workpieces in the electroplating solution caused by trolley shaking and positioning deviation, effectively improves the uniformity of plating thickness, and can adapt to the continuous operation requirements of automated production lines. It has good plating uniformity in vertical continuous electroplating (VCP).

[0031] In one embodiment, a second crossbeam 7 is further included, which is disposed between the supports 1 and located in the middle of the supports 1, and the second crossbeam 7 is provided with a third drive motor 71.

[0032] Specifically, the second crossbeam 7 is horizontally mounted in the middle of the two supports 1 and welded to the supports 1. This not only enhances the lateral rigidity of the supports but also provides a mounting carrier for the third drive motor 71 and helps to share the weight of the upper components.

[0033] In one embodiment, a second crossbeam 7 is further included, disposed between the supports 1 and located in the middle of the supports 1, and a warning light is provided on the second crossbeam 7.

[0034] Specifically, the warning light is fixedly installed on the side wall of bracket 1 and electrically connected to the equipment's control system. When the equipment is running normally, the warning light is solid green; when the equipment malfunctions (such as motor overload or sensor abnormality), the warning light flashes red and is accompanied by a buzzer to remind the operator to handle the situation in a timely manner and ensure operational safety.

[0035] In one embodiment, a second crossbeam 7 is further included, disposed between the supports 1 and located in the middle of the supports 1. The second crossbeam 7 is provided with a first position sensor 53 on the horizontal moving device 5.

[0036] Specifically, the main function of the sensor is: transmission coordination: the first drive gear 411 and the symmetrically arranged first driven gear 413 form a clamping group, and synchronous rotation is achieved through the bearing 412. Since the transmission wheels are symmetrically clamped on both sides of the second track 61, and the wheel surface and the track contact surface are made of wear-resistant rubber or quenched steel, sufficient friction can be generated to avoid transmission slippage.

[0037] Descent process: The second drive motor 41 rotates forward, the transmission wheel set rolls down along the second track 61, the lifting rod 63 descends slowly, the workpiece is gradually immersed in the electroplating solution until the bottom sensor is triggered, the motor stops, and the workpiece remains immersed in the electroplating solution. Ascent process: After electroplating is completed, the control system issues an ascent command, the second drive motor 41 reverses, the transmission wheel group rolls upward, the lifting rod 63 drives the workpiece to rise, and the waste liquid on the surface of the workpiece drips into the drainage tank and is introduced into the waste liquid box. Limit stop: When the lifting rod 63 rises to the preset position at the top, the top sensor is triggered, the motor stops, the lifting device completes one lifting cycle, and waits for the horizontal moving device to transfer the workpiece to the next process.

[0038] In one embodiment, a second crossbeam 7 is also included, which is disposed between the supports 1 and located in the middle of the supports 1. The second crossbeam, the lifting device 6 includes a second rail 61 and rollers 62 arranged in a vertical direction, the rollers 62 are symmetrically arranged and clamp the second rail 61 in the middle.

[0039] Specifically, because the transmission wheels are symmetrically clamped on both sides of the second track 61, and the contact surfaces between the wheel surfaces and the track are made of wear-resistant rubber or quenched steel, sufficient friction can be generated to prevent transmission slippage.

[0040] Power start: After receiving the lifting command, the control system starts the first drive motor 21 (forward rotation achieves descent, reverse rotation achieves ascent), and the motor outputs rotational power, which is transmitted to the roller 62.

[0041] Power conversion: The rotational motion of the linkage bearing 22 is converted into linear lifting motion. When the roller 62 rolls along the side wall of the second track 61, it is restricted by the vertical guidance of the second track 61 and cannot produce lateral deviation, thereby driving the lifting device 6 to move vertically along the track. The smoothness and positioning accuracy of the lifting process rely on the dual guarantee of "guide rail guidance + motor speed control" to ensure that the lifting rod 63 always moves in the vertical direction and avoids the workpiece tilting and colliding with the electroplating tank.

[0042] Speed ​​and stroke control: The second drive motor 41 is a servo motor that supports stepless speed regulation. During descent, the motor operates at low speed, allowing the workpiece to be slowly immersed in the electroplating solution, avoiding splashing. During ascent, the speed can be adjusted as needed, balancing efficiency and stability. Simultaneously, the motor has a built-in encoder that provides real-time feedback of the rotation angle, which is then converted into the lifting height of the lifting rod 63, achieving precise stroke control (with the help of sensors, a positioning accuracy of ±0.5mm can be achieved).

[0043] Workpiece bearing and fixing: The lifting rod 63 is a direct bearing component, and the top or middle is equipped with a workpiece clamp for fixing the workpiece to be electroplated; the lifting rod 63 and the lifting actuator are rigidly connected by bolts to ensure no shaking when bearing load, and it is suitable for medium load requirements of 50-200kg.

[0044] In one embodiment, a second crossbeam 7 is further included, which is disposed between the supports 1 and located in the middle of the supports 1. A lifting rod 63 is provided on the second crossbeam and the second track 61. The lifting rod 63 is integrated with the roller and connected to the linkage bearing 22. The lifting rod 63 is provided with a drainage groove 631.

[0045] Specifically, the waste liquid guiding mechanism works in synergy, with the lifting device 6 linked to the diversion tank 631 to achieve real-time recovery of electroplating waste liquid and avoid pollution. The function of the drainage groove 631: The drainage groove 631 on the lifting rod 63 is designed with an inclination (the groove opening faces the first waste liquid box 54). When the workpiece is raised after electroplating, the electroplating waste liquid attached to the surface will drip down along the workpiece surface into the drainage groove 631 of the lifting rod 63.

[0046] In one embodiment, a second crossbeam 7 is further included, which is disposed between the supports 1 and located in the middle of the supports 1. The second crossbeam, the lifting device 6 is provided with a second position sensor 64, which is located at the highest point of the movement of the lifting rod 63.

[0047] Specifically, to precisely control the lifting stroke and avoid the risk of overtravel collisions, the second position sensor 64 is precisely installed at the highest point of the lifting rod 63's movement trajectory. Through hardware sensing and system linkage, it achieves rigid limit control of the lifting stroke, ensuring the safety and stability of equipment operation. Electrically connected to the equipment control system, it can transmit sensing signals in real time. The installation position is limited: the installation coordinates of the second position sensor 64 strictly correspond to the maximum allowable lifting height of the lifting rod 63.

[0048] When the electroplating line trolley performs a lifting operation, the lifting rod 63 moves upward along the second track 61. As the lifting rod 63 gradually approaches the preset highest point, its top trigger block gradually approaches the sensing surface of the second position sensor 64. When the lifting rod 63 reaches the maximum allowable rising height, the trigger block enters the sensor's sensing range, and the sensor immediately generates an electrical signal and transmits it to the equipment control system. After receiving the signal, the control system immediately cuts off the power output of the lifting drive motor, and the lifting rod 63 stops rising, thus achieving travel limit protection.

[0049] In one embodiment, a second crossbeam 7 is further included, which is disposed between the supports 1 and located in the middle of the supports 1. The first crossbeam 52 is provided with a rotating hole 521, and the bearing 412 passes through the rotating hole 521.

[0050] Specifically, the mating structure between the first crossbeam 52 and the bearing 412 ensures stable transmission of the horizontal moving device 5. The first crossbeam 52 has a rotating hole 521, and the bearing 412 is precisely inserted into the rotating hole 521, forming a rigid transmission connection of "crossbeam-bearing-drive gear", realizing the error-free transmission of horizontal moving power and improving the stability and transmission efficiency of the equipment operation.

[0051] The first crossbeam 52 is integrally formed from high-strength alloy material, possessing excellent rigidity and resistance to deformation. The two first crossbeams 52 are arranged in parallel and symmetrically, and are fixedly connected to components such as racks and wheels to form the main frame of the horizontal moving device 5.

[0052] The rotating hole 521 is a pre-machined hole on the first crossbeam 52, located at the end of the crossbeam near the drive system. The axis of the hole is coaxial with the axis of rotation of the horizontal drive gear, ensuring that there is no offset in the transmission after the bearing is installed.

[0053] Bearing 412: A deep groove ball bearing (or a self-aligning roller bearing selected according to load requirements) is used as a key rotating component for power transmission. The inner ring is interference-fitted with the first drive gear / linkage shaft, and the outer ring is tightly fitted with the inner wall of the rotating hole 521 to achieve flexible transmission of driving power and load bearing.

[0054] Related components: The bearing 412 forms a transmission linkage with the first drive gear and the first driven gear. The radial force and axial force generated when the gear meshes with the rack are transmitted to the first crossbeam 52 through the bearing 412 to ensure the stability of the power transmission path.

[0055] In one embodiment, a second crossbeam 7 is also included, which is disposed between the supports 1 and located in the middle of the supports 1. The second crossbeam, the horizontal moving device 5 also includes a first waste liquid box 53, and a second waste liquid box 11 is disposed at the bottom of the supports 1. The first waste liquid box 53 is located above the second waste liquid box 11 and is connected to the second waste liquid box 11 through a pipe.

[0056] Specifically, the horizontal moving device 5 integrates a first waste liquid box 53, and a second waste liquid box 11 is fixedly installed at the bottom of the bracket 1. The first waste liquid box 53 is located directly above the second waste liquid box 11, and the two are sealed and connected through a pipe to form a layered waste liquid recycling closed loop of "upper layer collection - middle layer diversion - lower layer storage", which prevents electroplating waste liquid leakage and pollution, while ensuring the coordinated operation of horizontal movement and waste liquid collection.

[0057] The first waste liquid box 53 serves as the primary waste liquid collection unit, fixedly connected to the two first crossbeams 52 (erected between the crossbeams). It moves synchronously along the first track with the horizontal moving device, ensuring real-time collection of waste liquid without any omissions during workpiece transfer. The second waste liquid box 11 is used for centralized storage of waste liquid. It adopts an embedded design and is fixed to the bottom of the two support beams 12. It has a long trough-shaped structure, covering the entire movement trajectory range of the horizontal moving device, ensuring that the waste liquid guided by the first waste liquid box can be accurately collected without the risk of spillage.

[0058] During electroplating, the electroplating solution (such as chromium plating solution, nickel plating solution, etc.) adhering to the surface of the workpiece will drip down along the drainage channel of the lifting rod 63, or splash due to vibration during horizontal movement; the first waste liquid box 53 moves synchronously with the horizontal moving device, and the dripping waste liquid is quickly collected to the bottom drainage port through the internal inclined guide slope, and accurately introduced into the second waste liquid box 11 below through the connecting pipe; the second waste liquid box 11 centrally stores the waste liquid, completing the closed-loop recycling.

[0059] In one embodiment, a second crossbeam 7 is also included, disposed between the supports 1 and located in the middle of the supports 1. The second crossbeam, the horizontal moving device 5 includes two first crossbeams 52, and the first waste liquid box 53 is mounted between the two first crossbeams 52.

[0060] Specifically, the horizontal moving device 5 includes two parallel and symmetrically arranged first crossbeams 52, and the first waste liquid box 53 is mounted between the two first crossbeams 52 to ensure that the waste liquid box is firmly installed and evenly stressed, and can also run smoothly and synchronously with the horizontal moving device 5, so as to achieve seamless coordination between waste liquid collection and workpiece transfer.

[0061] Two first crossbeams 52, serving as the core load-bearing frame of the horizontal moving device, are arranged symmetrically on both sides of the device, with their spacing precisely matched to the width of the first waste liquid box 53. Wheels are mounted at the bottom of the crossbeams, the tops are fixedly connected to racks, and the bottoms are adapted to the first track, serving as both the power transmission carrier and the mounting foundation for the first waste liquid box. The two ends of the first waste liquid box 53 are fixed to pre-set mounting seats at the bottom of the two first crossbeams 52 by bolts, positioned centrally between the crossbeams to ensure balanced force distribution.

[0062] When the horizontal moving device is running, the second drive motor drives the two first crossbeams 52 to move synchronously along the first track through gear-rack meshing. The first waste liquid box 53, which is set between the crossbeams, moves synchronously with the crossbeams. During the electroplating operation, the waste liquid dripping from the surface of the workpiece falls into the centrally arranged first waste liquid box 53 along the guide groove of the lifting rod 63. Because the box is set between the two crossbeams, the waste liquid box always remains stable regardless of the movement state of the horizontal moving device (acceleration, deceleration, constant speed). The waste liquid is collected to the guide port through the guide slope and introduced into the second waste liquid box 11 through the pipeline to achieve stable collection.

[0063] The working principle of this device is as follows: The workpiece to be electroplated is fixed to the lifting rod 63 of the lifting device 6 by a clamp. The operator sets the horizontal movement path and lifting height through the control system. The second drive motor 41 starts, and through the meshing transmission of the first drive gear 411 and rack 51, it drives the horizontal moving device 5 to move along the first track 31 to above the target electroplating tank. The first drive motor 21 starts, and through the cooperation of the transmission wheel 62 and the second track 61, it drives the lifting rod 63 to descend, immersing the workpiece in the electroplating tank for electroplating. After electroplating, the first drive motor 21 reverses, driving the lifting rod 63 to rise to the preset height. At the same time, the drainage channel 631 on the lifting rod 63 guides the waste liquid on the surface of the workpiece into the first waste liquid box 54, and then into the second waste liquid box 11 through the pipe. The second drive motor 41 starts again, transferring the workpiece to the next process (such as the cleaning tank or drying area), completing one transfer operation. During the operation, the warning light 11 provides real-time feedback on the equipment status, and the sensor provides limit protection for the lifting stroke to ensure the safe and stable operation of the equipment.

[0064] The complete workflow of this device: Workpiece fixing: The workpiece to be electroplated is fixed on the lifting rod 63 by a clamp, and the control system sets the lowering height (matching the depth of the electroplating tank). Descent process: The first drive motor 21 rotates forward, the transmission wheel set rolls downward along the second track 61, the lifting rod 63 descends slowly, the workpiece is gradually immersed in the electroplating solution until the bottom second position sensor 64 is triggered, the first drive motor 21 stops, and the workpiece remains immersed in the electroplating solution. Ascent process: After electroplating is completed, the control system issues an ascent command, the second drive motor 41 reverses, the transmission wheel group rolls upward, the lifting rod 63 drives the workpiece to rise, and the waste liquid on the surface of the workpiece drips into the drainage tank 631 and is introduced into the waste liquid box. Limit stop: When the lifting rod 63 rises to the top preset position, the top second position sensor 64 is triggered, the first drive motor 21 stops, the lifting device 6 completes one lifting cycle, and waits for the horizontal moving device 5 to transfer the workpiece to the next process.

[0065] By incorporating a horizontal moving device 5 and a lifting device 6, the problem of low moving accuracy in traditional electroplating transfer equipment is overcome, enabling it to adapt to the continuous operation requirements of automated production lines and achieving better coating uniformity during vertical continuous electroplating (VCP). The above embodiments are merely illustrative of the technical solutions of the present invention and are not intended to limit it. Within the framework of the present invention, the technical features of the above embodiments or different embodiments can be combined, the steps can be implemented in any order, and many other variations of different aspects of the present invention as described above exist.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
