Description

Technical Field

[0001] This invention relates to a feeding device and method for copper plating on the surface of printing rollers. Background Technology

[0002] Copper plating is one of the most widely used pre-plating layers in the electroplating industry. It is used on tin solder parts, lead-tin alloys, and zinc die castings before nickel, gold, and silver plating to improve the adhesion of the plating layer. Copper plating is also required in the production of printing rollers.

[0003] For example, Chinese Patent No. CN214655301U discloses a high-efficiency and stable copper plating device for special printing rollers, relating to the field of copper plating equipment technology. It includes a reaction tank and a printing roller. A chassis is fixedly installed at the bottom of the reaction tank, and two guide rails are fixedly fitted inside the reaction tank. An electric heating base is fixedly fitted at the right end of the chassis. This high-efficiency and stable copper plating device for special printing rollers, through the coordinated use of the electric heating base, electric heating tubes, connecting pins, and fixed columns, allows the electric heating base to supply power to the electric heating tubes during the copper plating process, causing the heating tubes to heat up. This raises the temperature at the bottom of the reaction tank, thus increasing the reaction temperature inside the tank and improving the copper plating efficiency. If the device is subjected to vibration during operation, the connecting pins will slide relative to the fixed columns, compressing the shock-absorbing springs. The shock-absorbing springs then contract to absorb the impact force generated by the vibration, maintaining the stability of the device.

[0004] However, the above-mentioned solution cannot be used simultaneously for feeding, copper plating, and unloading, which reduces the efficiency of copper plating and thus limits the production speed. In view of this, the present invention proposes a feeding device and feeding method for copper plating on the surface of printing rollers to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a feeding device and feeding method for copper plating on the surface of printing rollers, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0008] Multiple sets of positioning rings are provided on the mounting surface of the belt, and two sets of symmetrically arranged positioning rings move relative to each other.

[0009] As an improvement to the above technical solution, the support mechanism includes a support rod, with support plates fixedly installed at both ends of the support rod, and three sets of support rollers rotatably installed between the two sets of support plates, the support rollers contacting the inner wall of the belt.

[0010] As an improvement to the above technical solution, the belt is a corrosion-resistant belt, and the axis connecting the three sets of support rollers forms an equilateral triangle;

[0011] A drive motor is provided on the support plate, and the drive motor is connected to a set of support rollers at the top. The surface of the support rollers is provided with toothed grooves.

[0012] As an improvement to the above technical solution, multiple sets of adjusting rods are provided on the mounting surface of the belt, two sets of adjusting plates are symmetrically arranged on the adjusting rods, an adjusting screw is rotatably connected between the two sets of adjusting plates, and a sliding sleeve is slidably connected to the adjusting rods;

[0014] As an improvement to the above technical solution, two sets of operating plates are symmetrically arranged on the adjusting screw, and a partition is provided at the center of the adjusting screw.

[0015] As an improvement to the above technical solution, the adjusting screw is provided with a first threaded part and a second threaded part, the first threaded part and the second threaded part have opposite threads, and the first threaded part and the second threaded part are symmetrically arranged on the adjusting screw with partitions.

[0016] As an improvement to the above technical solution, two sets of limiting rods are symmetrically arranged on the mounting surface of the belt, and the limiting rods are provided with a fixed groove and a movable groove.

[0017] An installation rod is slidably disposed in the fixed groove, and multiple sets of adjustment rods are connected between two sets of installation rods. The adjustment rods slide in the movable groove.

[0018] As an improvement to the above technical solution, two sets of fixing blocks are symmetrically arranged on the limiting rod, and a fixing screw is threadedly connected to the fixing block. The fixing screw contacts the mounting rod, and a ball is provided on the fixing screw.

[0019] As an improvement to the above technical solution, two sets of fixing plates are symmetrically arranged on the electroplating box, the support rod is rotatably connected to the two sets of fixing plates, and a disturbance motor is provided on the fixing plate, the disturbance motor being drivenly connected to the support rod.

[0020] A feeding method for a feeding device for copper plating on the surface of a printing plate roller includes the following steps:

[0021] S1, Printing roller positioning:

[0022] Place the printing plate roller between the two sets of positioning rings, and rotate the adjusting screw to make the two sets of positioning rings move relative to each other until the connecting shaft of the printing plate roller extends into the two sets of positioning rings. Repeat the above steps to position multiple sets of printing plate rollers.

[0023] S2. Installation and loading:

[0024] Multiple sets of printing plate rollers are hoisted, and the mounting rod is inserted into the fixed groove. The adjusting rod slides in the movable groove until the multiple sets of printing plate rollers are placed on the mounting surface of the belt.

[0025] S3, Rotational Fixation:

[0026] In S2, during the installation and loading process, when the mounting rod extends into the fixing groove, the two sets of fixing screws facing the electroplating box are rotated first. When the mounting rod is placed in the fixing groove, the fixing screws limit the mounting rod, and at the same time, the remaining fixing screws are rotated so that the mounting rod is positioned between the two sets of fixing screws.

[0027] S4, Rotary Copper Plating:

[0028] The drive motor drives a set of support rollers to rotate, which in turn drives the belt to move, so that multiple sets of printing plate rollers move to another mounting surface, that is, multiple sets of printing plate rollers move into the electroplating box for electrolytic copper plating.

[0029] S5, Moving material discharge:

[0030] After copper plating is completed, the drive motor drives a set of support rollers to rotate, thereby driving the belt to move, so that multiple sets of printing plate rollers after copper plating are moved to another mounting surface, that is, multiple sets of printing plate rollers are moved out of the electroplating box.

[0031] S6, Shake Cleanup:

[0032] The disturbance motor drives the support rod to swing back and forth, which in turn drives the support plate and multiple sets of support rollers to swing, causing the residual solution on the multiple sets of printing plate rollers after the material is discharged to fall off quickly.

[0033] S7. Disassembly and unloading:

[0034] Rotate the adjusting screw near the drive motor and hoist multiple sets of printing rollers to detach them from the belt. In this step, repeat steps S1, roller positioning, S2, installation and feeding, S3, rotation and fixing, S4, rotation and copper plating, S5, moving and discharging, and S6, shaking and cleaning to perform copper plating on multiple sets of printing rollers.

[0035] Compared with the prior art, the beneficial effects of the present invention are:

[0036] When copper plating multiple sets of printing rollers, the printing rollers are placed between two sets of positioning rings until the connecting shaft of the printing rollers extends into the two sets of positioning rings. The above steps are repeated to position the multiple sets of printing rollers so that the multiple sets of printing rollers are placed on the belt. Then the support mechanism drives the belt to move, so that the multiple sets of printing rollers move to another mounting surface, that is, the multiple sets of printing rollers move into the electroplating box for electrolytic copper plating.

[0037] After copper plating is completed, the support mechanism drives the belt to continue moving, so that the multiple sets of printing rollers after copper plating are moved to another mounting surface, that is, the multiple sets of printing rollers can be removed from the electroplating box;

[0038] With the support mechanism and belt coordination described above, since the feeding, copper plating and unloading are respectively set on the three mounting surfaces of the belt, the feeding, copper plating and unloading actions can be performed simultaneously, which can improve the efficiency of copper plating.

[0039] Through the coordination between the aforementioned support mechanism and belts, multiple sets of printing plate rollers can be driven into the electroplating box simultaneously for electroplating operations, ensuring that the copper plating quality of multiple sets of printing plate rollers is the same and preventing defective products from appearing.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Example:

[0049] like Figure 1-6 As shown, this embodiment proposes a feeding device for copper plating on the surface of a printing roller, including an electroplating box 10, a support mechanism 40 is provided inside the electroplating box 10, a belt 20 is provided on the support mechanism 40, and the support mechanism 40 drives the belt 20 to move, and the support mechanism 40 evenly distributes the belt 20 into three mounting surfaces.

[0050] Multiple sets of positioning rings 30 are provided on the mounting surface of the belt 20, and two sets of symmetrically arranged positioning rings 30 move relative to each other.

[0051] In this embodiment, when copper plating multiple sets of printing rollers, the printing rollers are placed between two sets of positioning rings 30 until the connecting shaft of the printing rollers extends into the two sets of positioning rings 30. The above steps are repeated to position the multiple sets of printing rollers so that the multiple sets of printing rollers are placed on the belt 20. Then the support mechanism 40 drives the belt 20 to move, so that the multiple sets of printing rollers move to another mounting surface, that is, the multiple sets of printing rollers move into the electroplating box 10 for electrolytic copper plating.

[0052] After copper plating is completed, the support mechanism 40 drives the belt 20 to continue moving, so that the multiple sets of printing rollers after copper plating are moved to another mounting surface, that is, the multiple sets of printing rollers can be removed from the electroplating box 10.

[0053] Through the cooperation between the support mechanism 40 and the belt 20, since the feeding, copper plating and unloading are respectively set on the three mounting surfaces of the belt 20, the feeding, copper plating and unloading actions can be performed simultaneously, which can improve the efficiency of copper plating.

[0054] Through the cooperation between the support mechanism 40 and the belt 20, multiple sets of printing plate rollers can be driven into the electroplating box 10 for electroplating operations at the same time, which can ensure that the copper plating quality of multiple sets of printing plate rollers is the same and prevent defective products from appearing.

[0055] Specifically, the support mechanism 40 includes a support rod 41, with support plates 44 fixedly installed at both ends of the support rod 41. Three sets of support rollers 42 are rotatably installed between the two sets of support plates 44, and the support rollers 42 are in contact with the inner wall of the belt 20.

[0056] In this embodiment, when the belt 20 moves, the support roller 42 rotates. Through the contact between the support roller 42 and the surface of the belt 20, the belt 20 is driven to move, which facilitates the loading, copper plating and unloading of the printing plate roller.

[0057] Specifically, the belt 20 is a corrosion-resistant belt, and the axis connecting the three sets of support rollers 42 forms an equilateral triangle.

[0058] Specifically, a drive motor 43 is provided on the support plate 44. The drive motor 43 is connected to a set of support rollers 42 at the top. The surface of the support rollers 42 is provided with toothed grooves 421 to improve friction and thus drive the belt 20 to move more stably.

[0059] In this case, drive motor 43 is a servo motor.

[0060] Specifically, multiple sets of adjusting rods 70 are provided on the mounting surface of the belt 20, and two sets of adjusting plates 71 are symmetrically arranged on the adjusting rods 70. An adjusting screw 72 is rotatably connected between the two sets of adjusting plates 71, and a sliding sleeve 61 is slidably connected on the adjusting rods 70.

[0061] The positioning ring 30 is provided with a positioning rod 60, which is threadedly connected to the adjusting screw 72 and connected to the sliding sleeve 61.

[0062] Specifically, two sets of operating plates 73 are symmetrically arranged on the adjusting screw 72, and a partition plate 722 is arranged at the center of the adjusting screw 72.

[0063] Specifically, the adjusting screw 72 is provided with a first threaded portion 721 and a second threaded portion 723, the first threaded portion 721 and the second threaded portion 723 have opposite threads, and the first threaded portion 721 and the second threaded portion 723 are symmetrically arranged on the adjusting screw 72 with a partition plate 722.

[0064] In this embodiment, when the printing plate roller is installed, the printing plate roller is placed between two sets of positioning rings 30, and the adjusting screw 72 is rotated to make the two sets of positioning rings 30 move relative to each other until the connecting shaft of the printing plate roller extends into the two sets of positioning rings 30. The above steps are repeated to position multiple sets of printing plate rollers.

[0065] The movable positioning ring 30, as described above, facilitates the installation of printing rollers of different lengths and can also position multiple sets of printing rollers, making it easier to load and unload multiple sets of printing rollers in batches and transfer them, thus improving the efficiency of copper plating.

[0066] Specifically, two sets of limiting rods 21 are symmetrically arranged on the mounting surface of the belt 20, and the limiting rods 21 are provided with a fixed groove 25 and a movable groove 26.

[0067] An installation rod 50 is slidably disposed in the fixed groove 25, and multiple sets of adjustment rods 70 are connected between two sets of installation rods 50. The adjustment rods 70 slide in the movable groove 26.

[0068] In this case, both the limiting rod 21 and the mounting rod 50 are made of elastic rubber material.

[0069] Specifically, two sets of fixing blocks 22 are symmetrically arranged on the limiting rod 21. The fixing blocks 22 are threadedly connected to fixing screws 23. The fixing screws 23 are in contact with the mounting rod 50. A ball 24 is provided on the fixing screws 23.

[0070] In this embodiment, when multiple sets of printing plate rollers are being fed, the multiple sets of printing plate rollers are hoisted, and the mounting rod 50 extends into the fixed groove 25, and the adjusting rod 70 slides in the movable groove 26 until the multiple sets of printing plate rollers are placed on the mounting surface of the belt 20.

[0071] When the mounting rod 50 extends into the fixing groove 25, the two sets of fixing screws 23 facing the electroplating box 10 are rotated first. When the mounting rod 50 is placed in the fixing groove 25, the fixing screws 23 limit the mounting rod 50. At the same time, the remaining fixing screws 23 are rotated so that the mounting rod 50 is positioned between the two sets of fixing screws 23.

[0072] The fixing screw 23, as described above, can limit the mounting rod 50, thereby ensuring the stability of multiple printing rollers during copper plating.

[0073] Specifically, two sets of fixing plates 11 are symmetrically arranged on the electroplating box 10, and the support rod 41 is rotatably connected to the two sets of fixing plates 11. A disturbance motor 12 is arranged on the fixing plate 11, and the disturbance motor 12 is connected to the support rod 41 in a transmission manner.

[0074] In this embodiment, the disturbance motor 12 drives the support rod 41 to swing back and forth, thereby driving the support plate 44 and multiple sets of support rollers 42 to swing, so that the residual solution on the multiple sets of printing plate rollers after the material is discharged will fall off quickly.

[0075] A feeding method for a feeding device for copper plating on the surface of a printing plate roller includes the following steps:

[0076] S1, Printing roller positioning:

[0077] Place the printing plate roller between the two sets of positioning rings 30, and rotate the adjusting screw 72 to make the two sets of positioning rings 30 move relative to each other until the connecting shaft of the printing plate roller extends into the two sets of positioning rings 30. Repeat the above steps to position multiple sets of printing plate rollers.

[0078] S2. Installation and loading:

[0079] Multiple sets of printing plate rollers are hoisted, and the mounting rod 50 is inserted into the fixed groove 25, while the adjusting rod 70 slides in the movable groove 26 until the multiple sets of printing plate rollers are placed on the mounting surface of the belt 20.

[0080] S3, Rotational Fixation:

[0081] In S2, during the installation and loading process, when the mounting rod 50 extends into the fixing groove 25, the two sets of fixing screws 23 facing the electroplating box 10 are rotated first. When the mounting rod 50 is placed in the fixing groove 25, the fixing screws 23 limit the mounting rod 50, and at the same time, the remaining fixing screws 23 are rotated so that the mounting rod 50 is positioned between the two sets of fixing screws 23.

[0082] S4, Rotary Copper Plating:

[0083] The drive motor 43 drives a set of support rollers 42 to rotate, thereby driving the belt 20 to move, so that multiple sets of printing plate rollers move to another mounting surface, that is, multiple sets of printing plate rollers move into the electroplating box 10 for electrolytic copper plating.

[0084] S5, Moving material discharge:

[0085] After copper plating is completed, the drive motor 43 drives a set of support rollers 42 to rotate, thereby driving the belt 20 to move, so that the multiple sets of printing plate rollers after copper plating are moved to another mounting surface, that is, the multiple sets of printing plate rollers are moved out of the electroplating box 10.

[0086] S6, Shake Cleanup:

[0087] The disturbance motor 12 drives the support rod 41 to swing back and forth, thereby driving the support plate 44 and multiple sets of support rollers 42 to swing, so that the residual solution on the multiple sets of printing plate rollers after the material is discharged can fall off quickly.

[0088] S7. Disassembly and unloading:

[0089] Rotate the adjusting screw 72 near the drive motor 43 and hoist multiple sets of printing plate rollers so that they are detached from the belt 20. At the same time, repeat steps S1, roller positioning, S2, installation and feeding, S3, rotation and fixing, S4, rotation and copper plating, S5, moving and discharging, and S6, shaking and cleaning to perform copper plating on multiple sets of printing plate rollers.
