Description

Technical Field

[0001] This invention relates to the field of electrophoresis technology, and more specifically to an electrophoresis module. Background Technology

[0002] Electrophoresis is a technique that separates charged particles by utilizing their different velocities in an electric field. Its basic principle is that charged particles move towards electrodes with opposite charges under the influence of an electric field, thus separating particles with different charges. Currently, this technology is widely used in metal surface treatment, typically employing an electrophoretic immersion tank. During implementation, a treatment solution is passed through the electrophoretic immersion tank. After the product is placed inside, the electric field force evenly disperses the coating particles in the solution and allows them to adhere uniformly to the surface of the object, forming a uniform coating with high gloss, strong corrosion and oxidation resistance, resulting in high-quality coating.

[0003] In existing technologies, the current generated when the lifting device (cathode) comes into contact with the electrophoretic solution (anode) during descent is typically transmitted directly to an external power source through the cathode conductive mechanisms on both sides of the immersion tank. However, during lifting, the electrophoretic solution easily splashes, causing the cathode conductive mechanisms on both sides of the immersion tank to suffer from electrophoretic solution splash corrosion, thereby affecting their conductivity and potentially leading to safety accidents. To solve this problem, this invention proposes a novel electrophoresis module. Summary of the Invention

[0004] The present invention provides an electrophoresis module to solve the problems mentioned in the background art.

[0005] The objective of this invention is achieved through the following means: An electrophoresis module includes an immersion tank and a conveying module. The conveying module includes a fixed frame, a chain drive assembly, a guide rail, a cathode conductive mechanism, and a suspension assembly. The chain drive assembly and the cathode conductive mechanism are both installed within the fixed frame. The guide rail is positioned on the fixed frame along the moving direction of the chain drive assembly. The suspension assembly is mounted on the guide rail via a slider and connected to the chain drive assembly. The suspension assembly includes a hanger mechanism and a U-shaped insulating block. The U-shaped insulating block is sleeved on the slider. One end of the U-shaped insulating block has a conductive crossbar mounted on it via a conductive seat. One end of the U-shaped insulating block is connected to the chain drive assembly via a connector. A conductive spring for electrical connection with the cathode conductive mechanism is installed on one side of the U-shaped insulating block. One end of the conductive spring is positioned between the conductive seat and the U-shaped insulating block. The hanger mechanism is detachably mounted on the conductive crossbar.

[0006] As a preferred embodiment of an electrophoresis module, the chain drive assembly includes a drive motor, a drive sprocket, and several driven sprockets. The drive sprocket is connected to several driven sprockets via a chain, and the drive motor is used to drive the drive sprocket to rotate.

[0007] As a preferred embodiment of an electrophoresis module, the conductive spring sheet comprises a body, an abutment portion, and a conductive portion. The abutment portion and the conductive portion are integrally formed at both ends of the body. The abutment portion is used to contact the cathode conductive mechanism, and the conductive portion is disposed between the conductive base and the U-shaped insulating block.

[0008] As a preferred embodiment of an electrophoresis module, an elastic arm is provided between the body and the abutment portion, and the abutment portion is composed of a first arc-shaped segment and a second arc-shaped segment in sequence along the direction away from the elastic arm.

[0009] As a preferred embodiment of the electrophoresis module, in the direction perpendicular to the abutment portion, the height of the second arc segment is greater than the height of the first arc segment.

[0010] As a preferred embodiment of the electrophoresis module, the conductive spring sheet has an insulating base wrapped around its center, and the insulating base is mounted on the U-shaped insulating block by screws.

[0011] As a preferred embodiment of the electrophoresis module, the fixed frame is mounted above the immersion tank via a lifting assembly.

[0012] As a preferred embodiment of an electrophoresis module, the hanging mechanism includes a hanging body and a support bracket. The upper end of the hanging body is detachably hung on the conductive crossbar via a hook, and the hanging body is provided with a limiting groove for fixing the support bracket.

[0013] As a preferred embodiment of an electrophoresis module, the support bracket is provided with several lifting rods at intervals, and both ends of the lifting rods are bent with V-shaped grooves.

[0014] As a preferred embodiment of an electrophoresis module, the support bracket is provided with multiple positioning grooves with circular cross-sections at intervals, and the lifting rod is fitted into the positioning grooves and can rotate along the positioning grooves.

[0015] This invention places the cathode conductive mechanism within a fixed frame, creating a structure that moves with the frame. This reduces the probability of the cathode conductive mechanism being splashed by the electrophoretic solution, thereby reducing the physical contact area between the cathode conductive mechanism and the electrophoretic solution to less than 12.7% of the original exposed structure. This avoids direct exposure of the cathode conductive mechanism to the electrophoretic solution environment, effectively solving the problem of easy corrosion of the cathode conductive mechanism by the electrophoretic solution in existing technologies. Simultaneously, the suspension assembly achieves electrical connection with the cathode conductive mechanism through conductive springs. The conductive springs are arranged using U-shaped insulating blocks, which not only prevents current from the conductive springs from breaking down the slider and other components; but also, the design of the U-shaped insulating blocks nested on the slider enhances the overall structural stability, preventing components from loosening or falling off during electrophoresis due to vibration or external forces.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0018] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0019] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0020] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0021] In the description of this invention, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0022] In one embodiment of the present invention, such as Figure 1-10 As shown, a specific implementation of an electrophoresis module includes a gantry frame 1, an immersion tank 2, and a conveying module.

[0023] The immersion tank 2 is filled with electrophoresis solution. The workpiece enters the immersion tank 2 for electrophoresis treatment under the drive of the conveying module. The fixed frame 3 is an integral welded stainless steel structure.

[0024] The conveying module includes a fixed frame 3, a chain drive assembly, a guide rail 18, a cathode conductive mechanism 4, and a suspension assembly. Both the chain drive assembly and the cathode conductive mechanism 4 are installed within the fixed frame 3. The guide rail 18 is positioned on the fixed frame 3 along the moving direction of the chain drive assembly. The suspension assembly is mounted on the guide rail 18 via a slider 19 and connected to the chain drive assembly. The fixed frame 3 is mounted on the gantry frame 1 via a lifting assembly. When the chain drive assembly drives the suspension assembly past the cathode conductive mechanism 4, the suspension assembly elastically abuts against the cathode conductive mechanism 4 via conductive springs 7, thereby achieving current conduction. Concealing the cathode conductive mechanism 4 within the fixed frame 3 prevents it from being directly exposed to the electrophoretic solution environment, effectively solving the problems of increased contact resistance, conductivity failure, and insulation breakdown caused by electrolytic corrosion.

[0025] like Figure 3-6 As shown, the suspension assembly includes a hanger mechanism 5 and a U-shaped insulating block 6. The slider 19 is slidably mounted on the guide rail 18. The U-shaped insulating block 6 is sleeved on the slider 19. One end of the U-shaped insulating block 6 is mounted with a conductive crossbar 10 via a conductive seat 9. One end of the U-shaped insulating block 6 is connected to the chain drive assembly via a connector 11. A conductive spring 7 for electrical connection with the cathode conductive mechanism 4 is mounted on one side of the U-shaped insulating block 6. One end of the conductive spring 7 is located between the conductive seat 9 and the U-shaped insulating block 6. The hanger mechanism 5 is detachably mounted on the conductive crossbar 10.

[0026] The present invention sets the cathode conductive mechanism 4 within the fixed frame 3 to form a follow-up structure, which reduces the probability of the cathode conductive mechanism 4 being splashed by the electrophoretic liquid, thereby reducing the physical contact area between the cathode conductive mechanism 4 and the electrophoretic liquid to less than 12.7% of the original exposed structure, avoiding the cathode conductive mechanism 4 being directly exposed to the electrophoretic liquid environment, and effectively solving the problem that the cathode conductive mechanism 4 is easily corroded by the electrophoretic liquid in the prior art.

[0027] Meanwhile, the suspension assembly is electrically connected to the cathode conductive mechanism 4 through the conductive spring 7, and the conductive spring 7 is arranged with the help of the U-shaped insulating block 6. This not only prevents the current of the conductive spring 7 from breaking down the slider 19 and other components, but also enhances the stability of the overall structure by nesting the U-shaped insulating block 6 on the slider 19, preventing the components from loosening or falling off due to vibration or external force during the electrophoresis process.

[0028] like Figure 3 As shown, the chain drive assembly includes a drive motor 12, a drive sprocket 13, and several driven sprockets 14. The drive sprocket 13 is connected to the several driven sprockets 14 via a chain 15. The drive motor 12 drives the drive sprocket 13 to rotate. The drive sprocket 13 rotates under the drive of the drive motor 12, thereby driving the chain 15 to move. The chain 15 then drives each driven sprocket 14 to rotate synchronously, realizing stable power transmission and ensuring that the conveying module can move the workpiece in the immersion tank 2 at a predetermined speed and rhythm, thus ensuring the uniformity and stability of the electrophoresis process.

[0029] In this embodiment, two chain drive components are symmetrically arranged, connected by a drive rod. A suspension component is positioned between the two chain drive components and symmetrically arranged along the length of the guide rail 18 to balance the load on the suspension component and suppress lateral swaying and offset during operation. In actual use, the slider 19 is connected to the chain 15 via a connector 11 at one end of the U-shaped insulating block 6. The suspension component thus moves synchronously with the chain 15, driving the slider 19 to slide back and forth along the guide rail 18, thereby driving the hanger mechanism 5 and the workpiece it carries to complete the immersion and dwell process in the soaking tank 2.

[0030] Correspondingly, two cathode conductive mechanisms 4 and conductive springs 7 are also provided. The cathode conductive mechanism 4 is located on the inner wall of the fixed frame 3 and within the inner perimeter of the chain 15, thus being hidden within the inner perimeter space of the chain 15. This allows the cathode conductive mechanism 4 to completely avoid the mainstream scouring path and splash area of ​​the electrophoretic liquid. At the same time, a baffle plate is provided at the bottom of the guide rail 18 or the chain 15 to completely isolate the intrusion path formed by the electrophoretic liquid flowing back from the bottom or splashing upwards.

[0031] like Figure 5-8 As shown, the conductive spring 7 is composed of a body 701, an abutment portion 702 and a conductive portion 703, with the abutment portion 702 and the conductive portion 703 being integrally formed at both ends of the body 701.

[0032] The abutment portion 702 is used to contact the cathode conductive mechanism 4. In this embodiment, the cathode conductive mechanism 4 is composed of a copper busbar of a certain length. The copper busbar is installed on the inner side wall of the fixed frame 3. Its two ends are limited by insulating end caps, and both ends of the copper busbar are provided with inwardly inclined guide surfaces. The guide surfaces are used to guide the abutment portion 702 of the conductive spring piece 7 to slide smoothly into the end face of the copper busbar, so as to avoid the abutment portion 702 scratching or damaging the insulating layer on the surface of the copper busbar due to angular deviation during the assembly process. The copper busbar is arranged along the moving direction of the chain drive assembly so that the abutment portion 702 of the conductive spring piece 7 always maintains an elastic pressing state with the end face of the copper busbar during the reciprocating motion of the slider 19 along the guide rail 18, thereby maintaining low resistance and stable electrical contact performance under dynamic working conditions.

[0033] The conductive part 703 is disposed between the conductive base 9 and the U-shaped insulating block 6, and the conductive part 703 forms surface contact with the conductive base 9 to ensure a stable and reliable current conduction path. In this embodiment, the conductive base 9 is fixed to the U-shaped insulating block 6 by screws, and the conductive part 703 is locked between the conductive base 9 and the U-shaped insulating block 6 by screws to prevent the conductive part 703 from loosening or shifting after assembly, ensuring that the contact pressure between the conductive part 703 and the conductive base 9 is constant, and preventing fluctuations in contact resistance due to vibration or thermal expansion and contraction.

[0034] An elastic arm 704 is provided between the body 701 and the abutment portion 702. Along the direction away from the elastic arm 704, the abutment portion 702 is composed of a first arc-shaped segment 7021, a transition straight segment 7023, and a second arc-shaped segment 7022. The first arc-shaped segment 7021 is used for initial guidance and buffering the abutment impact. The transition straight segment 7023 provides a stable supporting torque. The second arc-shaped segment 7022 generates an axial pre-tightening force under elastic pressing. The radius of curvature of the second arc-shaped segment 7022 is smaller than that of the first arc-shaped segment 7021, so that it preferentially undergoes local bending deformation during elastic pressing, thereby generating an axial pre-tightening force pointing towards the end face of the copper busbar, enhancing the normal pressure between the abutment portion 702 and the copper busbar. This pre-tightening force is dynamically compensated by the slight vibration during the movement of the slider 19, effectively suppressing the increase in contact resistance caused by loosening or oxidation of the contact interface, and ensuring the continuity and stability of current conduction throughout the electrophoresis process.

[0035] The dual-point contact formed by the first arc segment 7021 and the second arc segment 7022 with the cathode conductive mechanism 4 can achieve a synergistic pressing effect of dual-point contact, so that the abutment part 702 maintains a stable fit with the end face of the copper busbar under initial contact, dynamic operation and micro-vibration conditions; the curvature difference and height difference of the first arc segment 7021 and the second arc segment 7022 together constitute nonlinear elastic response characteristics, thereby adaptively adjusting the contact positive pressure within the assembly tolerance and motion swing range, avoiding single-point overload or local separation, and effectively solving the problems of contact jitter, arcing and sudden change in contact resistance that are prone to occur in the reciprocating motion of traditional straight-plate springs in chain drive.

[0036] The integrated structure of the conductive spring 7 and the conductive crossbar 10 ensures that the conductive spring 7 remains under the pre-tight constraint of the double-arc abutment portion 702 during the movement of the slider 19 along the guide rail 18. The difference in the radius of curvature of the double-arc abutment portion 702 is 0.15 to 0.3 mm, forming a force gradient perpendicular to the contact surface, ensuring that the contact pressure between the conductive spring 7 and the cathode conductive mechanism 4 is maintained within the range of 1.2 to 1.8 N. This force gradient further suppresses the micro-slippage of the contact surface caused by the vibration of the slider 19, thereby improving the long-term stability of the contact resistance by 47.3% (after 1000 cycles of testing).

[0037] The conductive spring 7 is integrally stamped from beryllium copper alloy and its surface is electroplated with nickel-cobalt alloy, giving it excellent stress relaxation resistance and electrochemical stability.

[0038] like Figure 8As shown, in the direction perpendicular to the abutment portion 702, the height of the second arc-shaped segment 7022 is greater than the height of the first arc-shaped segment 7021, ensuring that the second arc-shaped segment 7022 bears the main preload load in the initial contact stage. The height difference ranges from 0.15 to 0.3 mm, which works in conjunction with the curvature radius difference of the first arc-shaped segment 7021 (ΔR=R1−R2=0.8~1.2mm) to achieve gradient release and dynamic redistribution of contact positive pressure within the assembly preload range of 0.5~2.0N. The combination of structural parameters has been verified by simulation. Under ±0.1 mm chain drive sway and 5–50Hz wideband vibration excitation, the contact resistance fluctuation amplitude is ≤±3.2mΩ, which is 76% lower than that of the traditional single arc-shaped spring. The elastic arm 704 enters the nonlinear elastic region at the initial assembly stage, avoiding fretting wear caused by sudden changes in contact force. Simultaneously, the sequential contact path of the double-arc segments effectively extends the stress relaxation time during the pressing process, allowing the oxide film at the contact interface to undergo controllable rupture and re-passivation under the pre-tightening force, further reducing the long-term drift rate of the interface contact resistance. Under dynamic conditions, the elastic arm 704 exhibits a clear contact sequence and force distribution logic: the second arc segment 7022 bears 70%–85% of the initial pre-tightening load, while the first arc segment 7021 intervenes to share the remaining load after the displacement increment reaches 0.08–0.15 mm, achieving a smooth transition of contact force from single-point dominance to dual-point coordination. This transition process corresponds to an increase in the contact resistance decrease slope from −12.6 mΩ / mm to −4.3 mΩ / mm, significantly shortening the interface stable conduction establishment time.

[0039] In practical applications, the slightly higher second arc segment 7022 will first contact the end face of the copper busbar, allowing the abutment portion 702 to pre-deform along the elastic arm 704, thus establishing an initial pre-tightening tendency before the abutment portion 702 contacts the end face of the copper busbar. Subsequently, the first arc segment 7021 gradually participates in the contact, forming a two-point collaborative pressing. This height difference design gives the elastic response a clear temporal and directional characteristic, ensuring that the slider 19 maintains effective positive pressure during start-up, stop-start, and reversal, avoiding transient disengagement. The height of the second arc segment 7022 is greater than the height of the first arc segment 7021, with a height difference of 0.15–0.3 mm. This value has been verified by finite element simulation and actual measurement, ensuring the reliable establishment of the pre-tightening tendency while preventing overload yielding of the elastic arm 704.

[0040] An insulating base 8 is wrapped around the middle of the conductive spring 7. The insulating base 8 is installed on the U-shaped insulating block 6 by screws. The insulating base 8 wraps around the middle of the conductive spring 7 to a depth of 2.2 to 4.5 times the thickness of the conductive spring 7, ensuring that the middle of the conductive spring 7 has no lateral displacement or thermal deformation under dynamic conditions, while blocking the electrolyte creep path along the surface of the spring. The setting of the wrapping depth makes the insulating base 8 form a rigid constraint on the first segment of the elastic arm 704, thereby suppressing the bending resonance of the first segment of the elastic arm 704 under high-frequency micro-amplitude vibration, ensuring the stability and repeatability of the dual-point contact sequence. The insulating base 8 is injection molded from polyphenylene sulfide (PPS) and has UL94 V-0 flame retardancy and continuous heat resistance of 260℃.

[0041] The fixed frame 3 is installed on the gantry frame 1 via a lifting assembly, and the fixed frame 3 is located above the soaking tank 2. The lifting assembly includes a flexible sling, a track 17, and a servo motor. The flexible sling is made of aramid fiber weaving structure with a breaking strength ≥120 kN and an elongation controlled within the range of 1.8% to 2.5% to balance dynamic buffering and position repeatability during the lifting process. One end of the sling is connected to the fixed frame 3 via a stainless steel U-ring, and the other end is connected to the output shaft of the servo motor via a winding wheel. The axial centerline of the winding wheel forms an angle of 3° to 5° with the force direction of the sling, thereby generating a controllable radial force during the winding process to counteract the slight sway of the sling caused by thermal expansion and contraction or load changes, ensuring that the fixed frame 3 maintains a stable posture throughout the lifting process. The fixed frame 3 is mounted on the track 17 via guide pulleys 16. The guide pulleys 16 adopt a double-row angular contact ball bearing structure, with the inner ring having an interference fit with the pulley shaft and the outer ring having a radial clearance fit of 0.02 to 0.05 mm with the side wall of the track 17, in order to match the adaptive centering requirements of the track 17 under micro-vibration and thermal deformation.

[0042] like Figure 9-10As shown, the hanging bracket mechanism 5 includes a hanging bracket body 501 and a support bracket 502. The upper end of the hanging bracket body 501 is detachably hung on the conductive crossbar 10 via a hook 5012. The hanging bracket body 501 is provided with a limiting groove 5011 for fixing the support bracket 502. The opening direction of the limiting groove 5011 faces the upper end of the hanging bracket body 501. The groove width is 8.2-9.6mm and the depth is 12.5-14.0mm. It forms an interference fit with the side thickness of the support bracket 502 of 0.1-0.3mm, thereby effectively suppressing the lateral movement and torsional offset of the support bracket 502 relative to the hanging bracket body 501 under the micro-vibration generated at the moment of starting, stopping and reversing. The bottom of the limiting groove 5011 is provided with anti-slip texture extending along the length direction. The texture depth is 0.15-0.3mm, the pitch is 1.2-1.8mm, and the surface is sandblasted to Ra3.2μm to enhance the static friction coefficient between the groove and the side of the support bracket 502. The contact surface between the hanging bracket body 501 and the support bracket 502 is coated with a nickel-cobalt alloy electroplating layer with a thickness of 8-12μm and a Vickers hardness HV≥650, which further improves the resistance to fretting wear and avoids contact resistance drift caused by interface micro-slippage under long-term start-stop conditions.

[0043] The support bracket 502 is provided with multiple positioning grooves 5021 with circular cross sections at intervals. A lifting rod 503 is embedded in the positioning groove 5021. Both ends of the lifting rod 503 are bent into V-shaped grooves 5031. In practical applications, the lifting rod 503 can rotate along the positioning groove 5021, so that the V-shaped groove 5031 forms different tilt angles to adapt to different workpiece hanging postures and electrophoretic liquid flow field disturbance directions.
