Description

Technical Field

[0001] The present invention relates to the field of electroplating production lines, and in particular to an automatic unloading machine for electroplating production lines. Background Art

[0002] In the electroplating production process, coil loading and unloading are critical steps that influence overall automation levels and production efficiency. In traditional electroplating lines, coil loading and unloading often rely on manual operation with slings. Due to the heavy weight of the coils, this is not only labor-intensive and dangerous, but also prone to misaligned workpiece placement. Inaccurate placement can further lead to problems such as uneven material tension and inconsistent plating layer thickness during the electroplating process, seriously impacting electroplating quality and production continuity. The difficulty in ensuring consistency and accuracy in each loading and unloading process can lead to frequent production line downtime for adjustments, reducing overall production efficiency and economic benefits.

[0003] In the current prior art, for example, a Chinese invention patent application (publication number CN112777284A) discloses a flipping device and a roll flipping method, which include a frame and a flipping table hinged to the frame, the frame is equipped with a first driving assembly, the driving end of the first driving assembly is connected to the flipping table, and is used to drive the flipping table to flip around the hinge, the top surface of the flipping table is provided with a placement area for placing the roll, the head and tail directions of the placement area are consistent with the axial direction of the roll, the tail end of the placement area is fixedly connected to a block seat, the side of the placement area is hinged with a rotating member, the width direction of the rotating member is consistent with the head and tail directions of the placement area, the flipping table is equipped with a second driving assembly, the driving end of the second driving assembly is connected to the rotating member, and is used to drive the rotating member to rotate so as to compress or loosen the roll placed in the placement area.

[0004] According to the above-mentioned prior art, the tail end of the coil is supported and limited by a stopper, and the rotating member presses and fixes the coil from the outside toward the turning table, thereby firmly fixing the coil in the placement area and ensuring the stability of the coil turning process. The coil can be directly transferred from the previous workstation to the turning table through the head end of the placement area, without the need for an additional manipulator to transfer the coil from above. However, even with a stopper and a rotating member for limiting and pressing, if the coil has already slightly offset when entering the placement area, the subsequent turning process may cause the coil to deviate further from the ideal position, increasing the risk of unstable center of gravity. If the placement position of the coil deviates from expectations, it may affect the normal progress of subsequent processes, causing the production line to stagnate, requiring manual intervention and adjustment, and reducing production efficiency. Therefore, there is a need for an automatic unloader for an electroplating production line that can adjust the placement position of the coil. Summary of the Invention

[0005] In response to the problems existing in the existing technology, an automatic unloading machine for an electroplating production line is provided. The first supporting assembly and the second supporting assembly are driven to rotate by a turning table, so that the coil can be automatically turned from a vertical to a horizontal state. After the coil is horizontal, the movable support plate descends under the action of gravity and cooperates with the pressure regulator to drive the support rod to expand synchronously, ensuring that the coil is coaxial with the support shaft, avoiding the problem of unstable unwinding caused by eccentricity.

[0006] In order to solve the problems of the prior art, the present invention provides an automatic unloading machine for an electroplating production line, which is used for electroplating coils and includes a frame, wherein the frame is provided with a turning table for adjusting the coil from a vertical state to a horizontal state, and the turning table is provided with a first supporting assembly and a second supporting assembly with the same structure. When the turning table is in a working state, the first supporting assembly and the second supporting assembly are in an alternating turning state at a working position for horizontally supporting the coil. The first supporting assembly includes a support shaft and a movable support plate arranged on the support shaft, and the support shaft can rotate on the turning table for unwinding the coil during the electroplating process. A fixed support plate is provided on the support shaft and below the movable support plate, and a plurality of support rods for supporting the vertical coil are evenly distributed on the fixed support plate along the circumferential direction of the support shaft, and each support rod can move radially along the support shaft. A pressure regulator linked to all the support rods is provided between the fixed support plate and the movable support plate. When the movable support plate gradually descends through the pressure regulator under the action of the weight of the coil, all the support rods are in a synchronous outward expansion state, so that the position of the coil on the movable support plate is adjusted to remain coaxial with the support shaft.

[0007] Preferably, a slide plate is provided on the movable support plate, and a ball bearing that is in rolling contact with the movable support plate is provided on the slide plate. When the coil is adjusted in position by the outward expansion movement of the support rod, the coil slides smoothly on the movable support plate through the slide plate due to gravity.

[0008] Preferably, the pressure regulator includes multiple hydraulic parts supporting the movable support plate, and a pressure-applying part that cooperates with all the hydraulic parts and can be pushed along the axis parallel to the support shaft is slidably provided on the support shaft, and each support rod is provided with a pressure-receiving part that cooperates with the pressure-applying part and can be pushed along the axis perpendicular to the support shaft.

[0009] Preferably, the hydraulic component has a hydraulic rod fixedly connected to the movable support plate, and a push rod is rotatably provided on the support shaft, which contacts the hydraulic rod and the pressure member respectively. When the hydraulic rod descends, one end of the push rod is in a pressed down state and the other end is in an upward state, so that the pressure member acts on the pressure member.

[0010] Preferably, the hydraulic component also has a hydraulic chamber with a pressure relief port provided on the fixed support plate, the end of the hydraulic rod in contact with the push rod extends outward through the hydraulic chamber, and a piston fixedly connected to the hydraulic rod is provided in the hydraulic chamber. When all the hydraulic chambers slowly release pressure, the movable support plate supports the coil and gradually descends under the drive of the hydraulic rod.

[0011] Preferably, the pressure member is a cylinder slidably mounted on the support shaft, and the pressure member is a block fixedly connected to the support rod. The pressure member has an extended edge in contact with the push rod and an active surface cooperating with the pressure member.

[0012] Preferably, a first compression spring is provided between the movable support plate and the fixed support plate, and a second compression spring is provided between the pressure member and the fixed support plate. When the movable support plate is pressed down, the first compression spring and the second compression spring are both in a compressed state.

[0013] Preferably, a rubber pad is provided between the edge of the skateboard and the movable support plate. When the rubber pad is compressed, the skateboard is in a sliding state on the movable support plate. When the rubber pad is not compressed, the skateboard is in a centered state on the movable support plate.

[0014] Preferably, each support rod is provided with a rubber roller capable of flexibly contacting the coiled material.

[0015] Preferably, the fixed support plate is provided with a support portion capable of contacting all the rubber rollers to maintain their stability when supporting the coiled material.

[0016] Compared with the prior art, the present invention has the following advantages: 1. The present invention uses a turning table to drive the rotation of the first and second supporting assemblies, achieving automatic turning of the coil during unloading. This gradually turns the coil from a vertical position to a horizontal position, facilitating subsequent electroplating operations and eliminating the need for manual adjustment, thereby improving safety.

[0017] As the movable support plate descends under the weight of the coil, the pressure regulator drives the support rods to expand synchronously, ensuring the coil is coaxial with the support shaft. This prevents unstable unwinding or uneven tension caused by eccentricity. This ensures that the coil enters the electroplating process at a constant speed and direction, which helps maintain uniform chemical distribution and reaction consistency during the electroplating process, further improving the quality and consistency of the electroplated layer.

[0018] 2. The present invention effectively reduces the frictional resistance between the slide and the movable support plate by arranging balls between the two, so that the slide can slide freely as the position of the coil changes. Therefore, when the support rod expands outward to adjust the position of the coil, the coil always clings to the slide under the action of its own gravity and achieves fine adjustment, ensuring that it remains coaxial with the support shaft.

[0019] The stability and response speed of the slide plate following the sliding of the coil are improved, avoiding the problem of difficult or unstable adjustment caused by the heavy coil, and further ensuring the stability of the unwinding process and the uniformity of the electroplating effect.

[0020] 3. The present invention uses all hydraulic compartments to release pressure synchronously and slowly after the coil is rotated to a horizontal state, so that the coil can slowly descend along with the movable pallet, avoiding the movable pallet from falling instantly due to the gravity of the coil and colliding with the fixed pallet, causing damage to the movable pallet.

[0021] During this process, the movable support plate triggers the support rod to expand outward perpendicular to the axis of the support shaft, achieving adaptive internal support adjustment for the web. Simultaneously, the rubber roller forms a flexible contact with the web surface, providing uniform support and improving stability and fit during the adjustment process.

DETAILED DESCRIPTION

[0033] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] See also Figures 1-6 As shown, an automatic unloading machine for an electroplating production line is applied to an electroplating coil 1, comprising a frame 2, a turning table 3 for adjusting the coil 1 from a vertical state to a horizontal state is provided on the turning table 3, a first supporting assembly 4 and a second supporting assembly 5 of the same structure are provided on the turning table 3, when the turning table 3 is in a working state, the first supporting assembly 4 and the second supporting assembly 5 are in an alternating turning state at the working position of the horizontally supporting coil 1, the first supporting assembly 4 comprises a support shaft 41 and a movable support plate 42 arranged on the support shaft 41, the support shaft 41 can rotate on the turning table 3 for the coil 1 to be unwound during the electroplating process, the support A fixed support plate 43 is provided on the support shaft 41 and below the movable support plate 42. A plurality of support rods 431 for supporting the vertical coil 1 are evenly distributed on the fixed support plate 43 along the circumferential direction of the support shaft 41. Each support rod 431 can move radially along the support shaft 41. A pressure regulator 44 linked to all the support rods 431 is provided between the fixed support plate 43 and the movable support plate 42. When the movable support plate 42 gradually descends through the pressure regulator 44 under the action of the gravity of the coil 1, all the support rods 431 are in a synchronous outward expansion state, so that the position of the coil 1 on the movable support plate 42 is adjusted to remain coaxial with the support shaft 41.

[0035] A guide wheel assembly 6 is provided beside the turning table 3 for pulling out the coil 1 and guiding it for the subsequent electroplating process.

[0036] During the automatic unloading process of the electroplating production line, the coil 1 to be processed is first placed on the turning table 3, at which time the coil 1 is in a vertical position. In the initial state, one of the first supporting assembly 4 and the second supporting assembly 5 is in a working position for placing the coil 1 horizontally, and the other supporting assembly is in a working position for placing the coil 1 vertically.

[0037] During the movement of the coil 1, the coil 1 is moved by a sling (not shown). Once the coil 1 is placed on all the support rods 431, the sling is released from the coil 1, leaving it supported on the support rods 431. The weight of the coil 1 now acts on the support rods 431. As the turning table 3 rotates, the coil 1 gradually rotates to a horizontal position, and the weight of the coil 1 gradually acts on the movable support plate 42.

[0038] Once the coil 1 is completely horizontal, the movable support plate 42 begins to slowly descend under the action of gravity. As the movable support plate 42 descends, the pressure regulator 44 drives all the support rods 431 to expand outward synchronously, so that the support rods 431 support the coil 1 internally, ensuring that the coil 1 and the support shaft 41 remain coaxial, avoiding problems such as unstable unwinding or uneven tension caused by eccentricity.

[0039] As the coil 1 is continuously released from the current support assembly, the monitoring system continuously monitors the remaining amount of coil 1. When the coil 1 is about to be exhausted, the coil 1 is placed in advance on the support assembly to be used. After the coil 1 is exhausted, the turning table 3 rotates, driving the new coil 1 to rotate, causing it to flip from the vertical position to the horizontal working position, completing the loading of the new coil 1. Similarly, the support rod 431 and the pressure regulator 44 are used to match the newly loaded coil 1 and maintain its stability. At the same time, the support assembly originally in the working position flips back to the vertical state, ready for the next coil 1 to be replaced.

[0040] During the alternating turning and unwinding process, the unwinding end of the coil 1 sequentially passes over the guide wheel assembly 6 located beside the turning table 3. This ensures smooth unwinding and uniform tension of the coil 1, and accurately guides it into the subsequent electroplating process. The entire unwinding process is highly automated, eliminating the need for frequent manual intervention and ensuring worker safety.

[0041] See also Figure 3-Figure 7 As shown, a slide plate 421 is provided on the movable support plate 42, and a ball 4211 is provided on the slide plate 421 for rolling contact with the movable support plate 42. When the coil 1 is adjusted in position by the outward expansion movement of the support rod 431, the coil 1 is in a smooth sliding state on the movable support plate 42 through the slide plate 421 due to the action of gravity.

[0042] When the coil 1 is adjusted in position by the outward movement of the struts 431, the coil 1 fine-tunes its position under the action of the struts 431 to ensure that it remains coaxial with the support shaft 41. During this process, the coil 1 always clings to the slide 421 due to its own gravity, and the balls 4211 effectively reduce the frictional resistance between the slide 421 and the movable support plate 42, allowing the slide 421 to slide freely as the position of the coil 1 changes. This ensures the stability and flexibility of the coil 1 during the adjustment process and avoids the problem of being unable to adjust the position due to the excessive weight of the coil 1.

[0043] At the same time, the setting of the ball 4211 also improves the smoothness and response speed of the sliding process, so that the coil 1 can achieve smooth and continuous adaptive adjustment under different weight and diameter conditions, further enhancing the electroplating effect of the coil 1.

[0044] See also Figure 5-10 As shown, the pressure regulator 44 includes a plurality of hydraulic parts 441 supporting the movable support plate 42, and a pressure-applying part 442 is slidingly provided on the support shaft 41 and cooperates with all the hydraulic parts 441 and can be pushed along the axial direction parallel to the support shaft 41, and each support rod 431 is provided with a pressure-receiving part 443 that cooperates with the pressure-applying part 442 and can be pushed along the axial direction perpendicular to the support shaft 41.

[0045] When the coil 1 is placed on the movable support plate 42 and the movable support plate 42 moves downward due to gravity, the hydraulic component 441 in the pressure regulator 44 is subjected to pressure and evenly transmits the pressure to the pressure-applying component 442 slidably mounted on the support shaft 41. Under the action of the hydraulic pressure, the pressure-applying component 442 is pushed in a direction parallel to the axis of the support shaft 41, contacts the pressure-receiving component 443 on each support rod 431, and applies a thrust. After receiving the thrust, the pressure-receiving component 443 drives the support rod 431 to expand outward in a direction perpendicular to the support shaft 41, thereby realizing the adaptive internal support action of the support rod 431 on the coil 1, ensuring that the coil 1 and the support shaft 41 remain coaxial.

[0046] Through the cooperation of the movable support plate 42 and the pressure regulator 44, the coil 1 naturally droops due to its own gravity and clings to the slide plate 421, prompting the support rod 431 to adaptively adjust according to the actual position of the coil 1. This ensures that the coil 1 can be automatically centered and remains coaxial with the support shaft 41, avoiding problems such as unstable unwinding or uneven tension caused by eccentricity.

[0047] See also Figure 5-10 As shown, the hydraulic component 441 has a hydraulic rod 4411 fixedly connected to the movable support plate 42, and a push rod 411 is rotatably provided on the support shaft 41, which contacts the hydraulic rod 4411 and the pressure component 442 respectively. When the hydraulic rod 4411 descends, one end of the push rod 411 is in a pressed down state and the other end is in an upward state, so that the pressure component 442 acts on the pressure component 443.

[0048] When the coil 1 is placed on the movable support plate 42 and descends with it, the hydraulic rod 4411 fixedly connected to the movable support plate 42 moves downward synchronously. One end of the push rod 411 on the support shaft 41 rotates downward due to the downward pressure of the hydraulic rod 4411, while the other end tilts upward and pushes the pressure member 442 to move axially along the support shaft 41.

[0049] During the movement, the pressure-applying member 442 contacts the pressure-receiving member 443 on the support rod 431 and transmits the thrust to the pressure-receiving member 443, causing it to drive the support rod 431 to expand outward, thereby realizing adaptive internal support adjustment of the coil 1 and ensuring that the coil 1 and the support shaft 41 remain coaxial.

[0050] See also Figure 5-10 As shown, the hydraulic component 441 also has a hydraulic chamber 4412 with a pressure relief port 4413 provided on the fixed support plate 43. The end of the hydraulic rod 4411 in contact with the push rod 411 extends outward through the hydraulic chamber 4412. A piston 4414 fixedly connected to the hydraulic rod 4411 is provided in the hydraulic chamber 4412. When all the hydraulic chambers 4412 slowly release pressure, the movable support plate 42 supports the coil 1 and gradually descends under the drive of the hydraulic rod 4411.

[0051] When the coil 1 is rotated to a horizontal state, all the hydraulic chambers 4412 are depressurized synchronously, so that the movable support plate 42 slowly descends to trigger the outward expansion movement of the support rod 431 .

[0052] A position sensor is provided on the turning platform 3 corresponding to each movable support plate 42, which is not shown in the figure.

[0053] All hydraulic bins 4412 monitor the angle changes of the turning table 3 through position sensors. Once it is detected that the coil 1 has reached a horizontal position, a signal is sent to the control system, which uses the control system to synchronously release pressure on all hydraulic bins 4412, so that the movable support plate 42 slowly descends under the action of gravity, thereby triggering the outward expansion movement of the support rod 431 to automatically adjust the position of the coil 1.

[0054] Specifically, before the hydraulic chamber 4412 releases pressure, the movable support plate 42 remains in place to prevent the coil 1 from moving during rotation, which could result in the subsequent inability to adjust its position. After the hydraulic chamber 4412 buffers the pressure, the hydraulic rod 4411 gradually descends, driven by the movable support plate 42, pushing the piston 4414 to move within the hydraulic chamber 4412. The movable support plate 42 then slowly descends. At this point, the support rod 431 begins to respond to the outward expansion demand, gradually moving outward to fit the inner wall of the coil 1, achieving automatic positioning and support adjustment of the coil 1, ensuring that it remains coaxial with the support shaft 41.

[0055] See also Figure 5-10As shown, the pressure member 442 is specifically a cylinder slidably mounted on the support shaft 41, and the pressure member 443 is specifically a block fixedly connected to the support rod 431. The pressure member 442 has an extended edge 4421 in contact with the top rod 411 and an active surface 4422 that cooperates with the pressure member 443.

[0056] The matching action surface 4422 is an inclined surface where the pressure-applying member 442 and the pressure-receiving member 443 fit together.

[0057] When the push rod 411 moves downward under the drive of the hydraulic rod 4411, its end acts on the extended edge 4421 of the pressure member 442, pushing the pressure member 442 to slide along the support shaft 41. During the sliding process of the pressure member 442, its active surface 4422 contacts the active surface 4422 of the pressure block and applies a thrust, causing the support rod 431 to expand outward in a direction perpendicular to the support shaft 41, thereby achieving adaptive internal support adjustment for the coil 1 and ensuring that the coil 1 and the support shaft 41 remain coaxial.

[0058] See also Figure 6-Figure 8 As shown, a first compression spring 432 is provided between the movable support plate 42 and the fixed support plate 43, and a second compression spring 433 is provided between the pressure member 442 and the fixed support plate 43. When the movable support plate 42 is pressed down, the first compression spring 432 and the second compression spring 433 are both in a compressed state.

[0059] When the movable support plate 42 moves downward due to the weight of the coil 1, the first compression spring 432 disposed between the movable support plate 42 and the fixed support plate 43 is compressed, providing an upward buffering support force. At the same time, the pressure member 442 also applies pressure to the second compression spring 433 disposed between the movable support plate 42 and the fixed support plate 43 during the pushing process, causing the second compression spring 433 to be in a compressed state.

[0060] As the weight of the coil 1 decreases or is removed, the pressure on the movable support plate 42 decreases. The first compression spring 432 uses its elastic force to push the movable support plate 42 upward, gradually returning it to its initial position. This ensures that the movable support plate 42 can smoothly return to its original height, ready for the next operation. Similarly, the second compression spring 433 begins to exert its restoring force, pushing the pressure member 442 back to its initial position. This weakens the interaction between the pressure member 442 and the support rod 431, causing the support rod 431 to retract, preparing for the next round of adjustments and replacement of the coil 1.

[0061] See also Figure 6-Figure 9 As shown, a rubber pad layer 422 is provided between the edge of the slide plate 421 and the movable support plate 42. When the rubber pad layer 422 is compressed, the slide plate 421 is in a sliding state on the movable support plate 42. When the rubber pad layer 422 is not compressed, the slide plate 421 is in a centered state on the movable support plate 42.

[0062] When the coil 1 is adjusted, the coil 1 drives the slide 421 to move on the movable support 42. At this time, the rubber pad 422 between the edge of the slide 421 and the movable support 42 is compressed. As the weight of the coil 1 decreases or decreases, the slide 421 remains in the center of the movable support 42 due to the elastic force of the rubber pad 422, ready for the next adjustment.

[0063] See also Figure 3 、 Figure 4 and Figure 6-Figure 9 As shown, each support rod 431 is provided with a rubber roller 4311 that can flexibly contact the coiled material 1.

[0064] When the support rod 431 expands outward under the action of the pressure regulator 44 and contacts the inner wall of the web 1, the rubber roller 4311 on the support rod 431 forms a flexible contact with the surface of the web 1. The rubber roller 4311 deforms slightly during this contact process, conforming to the contour of the web 1 and providing uniform support, ensuring that the web 1 remains stable and coaxial during the adjustment and unwinding process.

[0065] See also Figure 6-Figure 9 As shown, the fixed support plate 43 is provided with a support portion 412 that can resist all the rubber rollers 4311 to maintain its stability when supporting the coil 1.

[0066] When the coil 1 is placed vertically on the rubber roller 4311, the weight of the coil 1 is concentrated on the rubber roller 4311. Therefore, in order to ensure the stability of the support rod 431, the support portion 412 on the fixed support plate 43 contacts the rubber roller 4311, so that the support rod 431 remains stable under the load. This prevents the support rod 431 from breaking due to excessive pressure, improves the structural stability and load-bearing capacity of the support rod 431, and ensures that the support rod 431 reliably supports the coil 1, improving the stability and smooth operation of the coil 1 during the unloading process.

[0067] The present invention utilizes a turning table 3 to drive the rotation of the first and second support assemblies 4 and 5, achieving automatic flipping of the web 1 from a vertical to a horizontal position, enhancing operational safety and automation. As the web 1 is placed horizontally, the movable support plate 42 descends under gravity and, in conjunction with the pressure regulator 44, drives the support rods 431 to expand synchronously, ensuring the web 1 is coaxial with the support shaft 41 and preventing uneven tension caused by eccentricity.

[0068] At the same time, a ball bearing 4211 is provided between the slide plate 421 and the movable support plate 42 to reduce friction resistance and enable the slide plate 421 to slide freely with the coil 1. This enhances the flexibility and stability of position fine-tuning, fully ensuring smooth unwinding and uniform and reliable electroplating effects.

[0069] The above embodiments merely represent one or more embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of the present invention. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present invention, and such modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the appended claims.
