Description

Technical Field

[0001] This application relates to the field of electroplating sheet material handling technology, and in particular to an automatic handling machine for continuous electroplating sheets. Background Technology

[0002] Electroplated sheets are mainly used for circuit connections and signal transmission in various electronic devices and electrical products. Electroplated sheets are deposited with a metal coating on their surface through an electroplating process to enhance conductivity, corrosion resistance, wear resistance, and oxidation resistance. Due to the high surface smoothness and the vulnerability of the coating, release paper is usually placed between electroplated sheets during continuous production, winding, storage, and transportation to reduce adhesion and scratches between sheets and ensure the stability of electroplating quality.

[0003] In related technologies, a roller of a corresponding size needs to be customized for the inner diameter of each electroplating sheet to wind the isolation fingers. When the model of the electroplating sheet changes, the operator needs to stop the machine, disassemble the original roller, and replace it with a fixed-size roller that matches the inner diameter of the new electroplating sheet.

[0004] However, in the continuous production of electroplated sheets, in order to match the inner diameter of the core of different models of electroplated sheets within the range, the existing technology still relies on the fixed size of the roll. When the model of the electroplated sheet changes, the machine needs to be stopped and the roll of the corresponding specification needs to be manually disassembled and replaced. The whole process takes a long time, and multiple sets of rolls of different sizes need to be stocked to meet the diverse needs of electroplated sheets. Utility Model Content

[0005] To address the aforementioned issues, this application provides an automatic feeding and receiving machine for continuous electroplating sheets.

[0006] The automatic feeding and receiving machine for continuous electroplating sheets provided in this application adopts the following technical solution: An automatic feeding and receiving machine for continuous electroplating sheets includes a housing, a rotating mechanism, and an expanding mechanism. The rotating mechanism and the expanding mechanism are coaxially fixed and fixedly connected to the housing. The expanding mechanism includes an expanding plate, a sliding sleeve, a support base, and a hinge rod. The sliding sleeve is fitted onto the outer wall of the support base and slides vertically on the support base. The inner wall of the sliding sleeve is slidably engaged with the outer wall of the support base. Several hinge rods and expanding plates are provided. The expanding plates are evenly distributed along the circumference of the sliding sleeve and are configured as arcs that conform to the circumferential contour. One end of the hinge rod is hinged to the outer wall of the sliding sleeve, and the other end of the hinge rod is hinged to the inner wall of the expanding plate.

[0007] By adopting the above technical solution, the housing rotation mechanism provides fixed support, and the rotation mechanism and expansion mechanism are coaxially fixed, ensuring the synchronization of their rotation. The support base provides vertical sliding guidance for the sliding sleeve. The sliding fit between the outer wall of the support base and the inner wall of the sliding sleeve ensures the stability and straightness of the sliding sleeve when it moves vertically. Since the expansion plate is set as an arc shape that fits the circumferential contour, when the sliding sleeve slides upward along the support base, the hinge rod hinged to the outer wall of the sliding sleeve will swing upward accordingly. The other end of the hinge rod and the hinge point of the inner wall of the expansion plate are subjected to force, causing the circumferentially evenly distributed expansion plates to contract towards the center of the sliding sleeve, thus reducing the circumferential diameter formed by the multiple expansion plates. Conversely, As the sliding sleeve slides downwards along the support base, the hinge rod swings down and applies an outward thrust to the expansion plates, causing each expansion plate to expand synchronously away from the center of the sliding sleeve, increasing the diameter of the overall enclosed circumference. With the help of the vertical sliding of the sliding sleeve along the support base, and in conjunction with the transmission action of the hinge rod, the circumferentially distributed arc-shaped expansion plates can be driven to contract or expand synchronously, adjusting the diameter of the overall enclosure. This not only flexibly adapts to the winding requirements of the release paper roll, but also allows for the setting of corresponding inner diameters for the cores of different types of electroplated sheet materials, reducing the need for custom-made reels for each inner diameter. When switching electroplated sheet material models, the diameter adjustment of several expansion plates is completed through the displacement of the sliding sleeve, reducing downtime for reel replacement and lowering the intensity of manual operation.

[0008] Preferably, the expansion mechanism further includes a sliding shaft, which is slidably built into the support base. A sliding block is fixedly provided on the outer wall of the sliding shaft. The support base has a first sliding groove, and the sliding block is slidably disposed in the first sliding groove. The sliding sleeve has a connecting groove, and the sliding block is inserted into the connecting groove.

[0009] By adopting the above technical solution, when the sliding shaft slides along the support base, the sliding block slides directionally along the first sliding groove. Since the sliding block and the connecting groove are engaged, the vertical displacement of the sliding shaft is directly transmitted to the sliding sleeve, thereby driving the sliding sleeve to slide vertically along the support base synchronously. This ensures the linkage between the sliding shaft and the sliding sleeve, providing a more reliable transmission guarantee for adapting to the inner diameter of different models of electroplated sheet cores. The first sliding groove limits the sliding stroke of the sliding block and constrains the sliding range of the sliding shaft. By means of the engagement between the sliding block and the connecting groove, the vertical movement range of the sliding sleeve is controlled, ensuring that the contraction and expansion of the expansion plate are always within the preset range for adapting to the inner diameter of different models of electroplated sheet cores.

[0010] Preferably, the expansion mechanism further includes a handle, which is fixedly connected to the upper end of the sliding shaft.

[0011] By adopting the above technical solution, the operator can directly hold the handle to drive the sliding shaft to move up and down along the support base. Through the cooperation of the sliding block and the connecting groove, the sliding sleeve is driven to slide vertically in sync, thereby controlling the contraction and expansion of the expansion plate. This allows the operator to easily adapt and adjust the inner diameter of the core of different models of electroplated sheet materials with less need for additional tools.

[0012] Preferably, the expansion mechanism further includes a base plate and a fixing plate. The base plate is sleeved on the lower side of the support base. The expansion plate is provided with a sliding plate, which is fixed to the inner wall of the expansion plate. The hinge rod is hinged to the sliding plate. The base plate is provided with a second sliding groove, in which the sliding plate is slidably disposed. The fixing plate is provided with a fixing groove, which is inserted into the end of the sliding plate away from the second sliding groove.

[0013] By adopting the above technical solution, since the sliding plate is slidably set in the second sliding groove, and since the bottom plate is sleeved on the lower side of the support base, the second sliding groove can provide a constant horizontal guide trajectory for the sliding plate due to the fixed position of the bottom plate. This further ensures that the expansion plate moves uniformly and synchronously in the circumferential direction during the contraction and expansion process, reducing the offset caused by changes in the guide reference. The fixed groove is inserted and matched with the end of the sliding plate away from the second sliding groove. When the expansion plate is adjusted to the target position, the position of the sliding plate is locked by the insertion limit, thereby fixing the position of the expansion plate. This reduces the loosening of the expansion plate position caused by external force during the winding of the release paper around the expansion plate, thereby ensuring the consistency of the release paper winding size and providing reliable protection for the electroplated plate coating.

[0014] Preferably, it also includes a receiving tray, the expansion mechanism is coaxially fixed with the receiving tray, and the receiving tray is provided with a receiving groove.

[0015] By adopting the above technical solution, the receiving tray and the expansion mechanism are fixed coaxially, which can ensure the synchronization of the rotation of the receiving tray and the expansion mechanism, reduce the deviation and wrinkles caused by relative rotation during the winding of the release paper, ensure the stability of the winding process and the regular shape of the paper roll. After the release paper is wound, the release paper is placed directly on the receiving tray. At the same time, since the receiving tray is equipped with a receiving groove, forklifts can insert into the receiving groove to transport the wound release paper, which improves the convenience of transporting the release paper.

[0016] Preferably, the rotating mechanism includes a connecting sleeve, a connecting shaft, and a drive motor. The connecting shaft is coaxially fixed with the output shaft of the drive motor. The connecting shaft is provided with a connecting plate. The connecting sleeve is sleeved on the connecting shaft and fixedly connected to the connecting plate. A fixing hole is provided at the end of the connecting sleeve away from the connecting plate. A connecting post is provided on the base plate, and the connecting post is inserted into the fixing hole.

[0017] By adopting the above technical solution, since the connecting shaft and the output shaft of the drive motor are coaxially fixed, the output shaft of the drive motor drives the connecting shaft to rotate. The connecting plate is fixedly connected to the connecting sleeve sleeved on the connecting shaft, so that the connecting sleeve rotates synchronously with the connecting shaft. The fixing hole and the connecting post of the base plate form an insertion fit, thereby driving the base plate to rotate. The expansion mechanism associated with the base plate rotates synchronously, ensuring the high efficiency and reliability of power transmission during the winding of the release paper.

[0018] Preferably, it also includes a material guiding mechanism, which includes a paper feeding tray, a guide wheel, and a support frame. The paper feeding tray is fixedly connected to the side wall of the machine housing, the guide wheel is rotatably supported on the support frame, and the support frame is installed on the upper surface of the machine housing.

[0019] By adopting the above technical solution, the paper feeding tray is fixedly connected to the side wall of the machine housing to carry the isolation paper roll to be fed. The guide wheel is supported on the support frame by rotation, and the support frame is installed on the upper surface of the machine housing to provide stable support for the guide wheel. With this setting, after the isolation paper is released from the paper feeding tray, it is guided and conveyed by the guide wheel in sequence, and finally conveyed to the expansion mechanism to form a continuous feeding process.

[0020] Preferably, the upper surface of the housing is provided with a plurality of mounting portions, and the support frame is fixed to the mounting portions.

[0021] By adopting the above technical solution, several mounting parts on the upper surface of the casing provide multiple installation options for the support frame. By installing the support frame in different mounting parts, the position of the guide roller can be flexibly adjusted. Operators can install the support frame in different mounting parts according to the specifications of the release paper and the actual supply requirements, reducing the problems of excessive or insufficient tension or directional deviation caused by fixed position, and ensuring that the release paper maintains appropriate tension and correct direction during the process of being conveyed from the paper tray through the guide roller to the expansion mechanism.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The sliding sleeve slides vertically along the support base and ensures smooth movement through sliding engagement with the support base. With the help of the hinge rod transmission, it can drive the circumferentially evenly distributed arc-shaped expansion plates to synchronously contract or expand, thereby adjusting the overall enclosure diameter. This can not only meet the needs of release paper winding, but also set the corresponding inner diameter for different models of electroplated sheet cores, reducing the need for custom-made special rolls. When switching the model of electroplated sheet, the diameter adjustment of several expansion plates can be completed by the displacement of the sliding sleeve, reducing the time loss of downtime for changing rolls and reducing the intensity of manual operation. 2. The sliding shaft is slidably installed in the support base, and the sliding block slides directionally along the first sliding groove. The sliding block is also engaged with the connecting groove, so that the vertical displacement of the sliding shaft can be directly transmitted to the sliding sleeve, which drives the sliding sleeve to slide vertically along the support base synchronously. At the same time, the first sliding groove limits the sliding stroke of the sliding block, constrains the sliding range of the sliding shaft, and thus controls the vertical movement range of the sliding sleeve, ensuring that the contraction and expansion of the expansion plate are always within the preset range of the inner diameter of the core of the electroplated sheet of different models. 3. The expansion mechanism rotates and is supported by the receiving tray, providing stable support for the wound release paper. The receiving tray is equipped with a receiving chute, which can be inserted by a forklift to transport the wound release paper, thereby improving the convenience of handling.

[0032] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0033] This application discloses an automatic feeding and receiving machine for continuous electroplating sheets. (Refer to...) Figure 1 An automatic feeding and receiving machine for continuous electroplating sheet includes a housing 1, a rotating mechanism 3, and an expanding mechanism 2. The rotating mechanism 3 and the expanding mechanism 2 are coaxially fixed and fixedly connected to the housing 1. The expanding mechanism 2 can adjust its inner diameter for different types of electroplating sheets to meet the diverse production needs of electroplating sheets. The rotating mechanism 3 provides fixed support for the housing 1. The coaxial fixing of the rotating mechanism 3 and the expanding mechanism 2 ensures the synchronicity of the rotation of the rotating mechanism 3 and the expanding mechanism 2.

[0034] Reference Figure 2 and Figure 4 Specifically, the expansion mechanism 2 includes an expansion plate 21, a sliding sleeve 22, a support base 23, and a hinge rod 24. The expansion plate 21 is a key component for adjusting the inner diameter. The expansion plate 21 is set in an arc shape that fits the circumferential contour. This shape can better fit the wound release paper. The sliding sleeve 22 is cylindrical. The expansion plate 21 is evenly arranged around the sliding sleeve 22, so that consistency in all directions can be ensured when adjusting the inner diameter.

[0035] Furthermore, the sliding sleeve 22 is fitted onto the support base 23, which is also cylindrical and has a hollow interior. The inner wall of the sliding sleeve 22 slides against the outer wall of the support base 23, allowing the sliding sleeve 22 to slide vertically on the support base 23. One end of the hinge rod 24 is hinged to the outer wall of the sliding sleeve 22, and the other end is hinged to the inner wall of the expansion plate 21. Several hinge rods 24 and expansion plates 21 are provided. In this embodiment, four expansion plates 21 and eight hinge rods 24 are provided. The four expansion plates 21 are evenly arranged circumferentially along the sliding sleeve 22. Each expansion plate 21 is matched with two hinge rods 24. The two hinge rods 24 are evenly distributed along the vertical direction of the expansion plate 21 and are arranged in parallel.

[0036] Reference Figure 5 Meanwhile, the expansion mechanism 2 also includes a sliding shaft 25, which is slidably disposed in the support base 23. A sliding block 251 is fixedly disposed on the outer wall of the sliding shaft 25. The support base 23 is provided with a first sliding groove 231. The sliding block 251 is slidably disposed in the first sliding groove 231. The sliding sleeve 22 is provided with a connecting groove 221. The outline of the connecting groove 221 matches the outline of the sliding block 251. The sliding block 251 and the connecting groove 221 are inserted and engaged.

[0037] This explains that when the sliding shaft 25 slides vertically along the inside of the support base 23, the sliding block 251 will slide directionally along the first sliding groove 231 of the support base 23. The first sliding groove 231 provides precise motion trajectory constraints for the sliding block 251, reducing the deviation of the sliding block 251 during movement, and also limits the sliding stroke of the sliding block 251 through the length of the first sliding groove 231. Since the sliding block 251 is inserted and engaged with the connecting groove 221, the vertical displacement of the sliding shaft 25 is directly transmitted to the sliding sleeve 22, causing the sliding sleeve 22 to slide vertically along the outer wall of the support base 23 in sync.

[0038] Meanwhile, since the expansion plate 21 is set to be an arc shape that fits the circumferential contour, and the expansion plate 21 is evenly distributed along the circumference of the sliding sleeve 22, the inner wall of each expansion plate 21 is hinged to the outer wall of the sliding sleeve 22 through two hinge rods 24. When the sliding sleeve 22 slides upward along the support seat 23 under the drive of the sliding shaft 25, the hinge rod 24 hinged to the outer wall of the sliding sleeve 22 will swing upward synchronously with the movement of the sliding sleeve 22. At this time, the end of the hinge rod 24 away from the sliding sleeve 22 will generate an inward pulling force. Since all the expansion plates 21 are evenly distributed along the circumference and the swing amplitude of each hinge rod 24 is consistent, this pulling force will drive all the expansion plates 21 to contract synchronously towards the center of the sliding sleeve 22, and finally reduce the circumferential diameter formed by the enclosed circle of multiple expansion plates 21.

[0039] Furthermore, as the sliding sleeve 22 slides downward with the sliding shaft 25, the hinge rod 24 swings downward accordingly. The hinge point between the hinge rod 24 and the inner wall of the expansion plate 21 is subjected to an outward thrust. Under the action of the thrust, each expansion plate 21 will expand synchronously in a direction away from the center of the sliding sleeve 22, thereby increasing the circumference diameter of the overall enclosure. Through this transmission logic, from the displacement of the sliding shaft 25 to the linkage of the sliding sleeve 22, and then to the swing of the hinge rod 24, the contraction and expansion of the expansion plate 21 are finally realized, and the adjustment of the enclosure diameter is precisely completed.

[0040] Meanwhile, the expansion mechanism 2 also includes a handle 28, which is fixedly connected to the upper end of the sliding shaft 25. The operator can directly hold the handle 28 to drive the sliding shaft 25 to move up and down along the support base 23. Through the cooperation of the sliding block 251 and the connecting groove 221, the sliding sleeve 22 is driven to slide vertically in sync, thereby controlling the contraction and expansion of the expansion plate 21. This allows the operator to easily adapt and adjust the inner diameter of the core of different models of electroplated sheet materials with less need for additional tools.

[0041] In addition, the expansion mechanism 2 also includes a base plate 26 and a fixing plate 27. The base plate 26 is sleeved on the bottom of the support base 23. The expansion plate 21 is provided with a sliding plate 211, which is fixed to the inner wall of the expansion plate 21. The hinge rod 24 is hinged to the sliding plate 211. The base plate 26 is provided with a second sliding groove 261, and the bottom of the sliding plate 211 is slidably disposed in the second sliding groove 261. Because it is sleeved on the bottom of the support base 23, the position of the base plate 26 is fixed. The second sliding groove 261 can provide a constant horizontal guide trajectory for the sliding plate 211, ensuring that the expansion plate 21 moves uniformly and synchronously in the circumferential direction during the contraction and expansion process, and reducing the offset caused by the change of the guide reference.

[0042] Reference Figure 3 Furthermore, the fixing plate 27 is provided with a fixing groove 271, which is inserted into the end of the sliding plate 211 away from the second sliding groove 261. When the expansion plate 21 is adjusted to the target position, the position of the sliding plate 211 is locked by the insertion limit, thereby fixing the position of the expansion plate 21. This reduces the loosening of the position of the expansion plate 21 caused by external force during the winding of the release paper around the expansion plate 21, thereby ensuring the consistency of the winding size of the release paper and providing reliable protection for the plating layer of the electroplated sheet.

[0043] In addition, it also includes a receiving tray 4, and the expansion mechanism 2 is coaxially fixed with the receiving tray 4. The coaxial fixing of the receiving tray 4 and the expansion mechanism 2 can ensure the synchronization of the rotation of the receiving tray 4 and the expansion mechanism 2, reduce the offset and wrinkles caused by relative rotation during the winding of the release paper, and ensure the stability of the winding process and the regular shape of the paper roll. After the release paper is wound, the release paper is placed directly on the receiving tray 4. At the same time, the receiving plate is provided with a receiving groove 41. Since the receiving tray 4 is provided with a receiving groove 41, the forklift can insert into the receiving groove 41 to transport the wound release paper, which improves the convenience of transporting the release paper.

[0044] Reference Figure 7 and Figure 8 On the other hand, the rotating mechanism 3 includes a connecting sleeve 31, a connecting shaft 32, and a drive motor 33. The connecting shaft 32 and the output shaft of the drive motor 33 are coaxially fixed, so that the power of the drive motor 33 can be directly transmitted to the connecting shaft 32. A connecting plate 321 is fixedly provided on the connecting shaft 32, and the connecting sleeve 31 is sleeved on the connecting shaft 32. The connecting sleeve 31 and the connecting plate 321 are fixedly connected. This connection method ensures that the connecting sleeve 31 and the connecting shaft 32 can rotate synchronously.

[0045] Furthermore, a fixing hole 311 is provided at the end of the connecting sleeve 31 away from the connecting plate 321, and a connecting post 262 is fixedly provided on the base plate 26. In this embodiment, there are two fixing holes 311 and two connecting posts 262. The fixing holes 311 and the connecting posts 262 correspond one-to-one, and the connecting posts 262 are inserted into the fixing holes 311.

[0046] This explains that, since the connecting shaft 32 is coaxially fixed with the output shaft of the drive motor 33, the output shaft of the drive motor 33 drives the connecting shaft 32 to rotate. The connecting plate 321 is fixedly connected with the connecting sleeve 31 sleeved on the connecting shaft 32, so that the connecting sleeve 31 rotates synchronously with the connecting shaft 32. The fixing hole 311 and the connecting post 262 of the base plate 26 form an insertion fit, thereby driving the base plate 26 to rotate. Through this connection method, the power of the rotating mechanism 3 can be transmitted to the expansion mechanism 2, and the expansion mechanism 2 then winds the isolation paper, ensuring the high efficiency and reliability of power transmission during the winding of the isolation paper.

[0047] In addition, in this embodiment, the drive motor 33 is a DC motor. The excellent speed regulation performance of the DC motor can smoothly adjust the speed as the inner diameter of the expansion plate 21 increases. Combined with the stable support provided by the expansion mechanism 2, it ensures that the release paper maintains uniform tension throughout the winding process.

[0048] Furthermore, it also includes a material guiding mechanism 5, which includes a paper feeding tray 51, a guide wheel 52, and a support frame 53. The paper feeding tray 51 is fixedly connected to the side wall of the housing 1. The paper feeding tray 51 is used to place the isolation paper roll. The paper feeding tray 51 is circular in shape, and a shaft 511 is provided on the upper surface of the paper feeding tray 51. The shaft 511 is vertically fixed in the middle of the upper surface of the paper feeding tray 51. The shaft 511 is used to install the isolation paper roll.

[0049] Meanwhile, the guide wheel 52 rotates and is supported on the support frame 53. The upper surface of the housing 1 is provided with a number of mounting parts 11. In this embodiment, there are three mounting parts 11. Each mounting part 11 is provided with a first mounting hole 111. The support frame 53 is provided with a mounting plate 531. The mounting plate 531 is provided with a corresponding second mounting hole 5311. The support frame 53 is fixed on the housing 1 by screws passing through the corresponding first mounting hole 111 and second mounting hole 5311.

[0050] This demonstrates that by installing the support frame 53 on different mounting parts 11, the position of the guide roller 52 can be flexibly adjusted. Operators can install the support frame 53 on different mounting parts 11 according to the specifications of the release paper and the actual supply requirements, reducing the problems of excessive or insufficient tension or directional deviation caused by fixed position, and ensuring that the release paper maintains appropriate tension and correct direction during the process of being conveyed from the paper tray 51 to the expansion mechanism 2 via the guide roller 52.

[0051] The implementation principle of the automatic feeding and receiving machine for continuous electroplating sheets in this application embodiment is as follows: According to the specifications of the electroplated sheet and the demand for release paper, the operator selects a suitable mounting part 11 on the upper surface of the housing 1, and fixes the support frame 53 by passing screws through the first mounting hole 111 of the mounting part 11 and the second mounting hole 5311 of the support frame 53 mounting plate 531. The position of the guide wheel 52 is adjusted, and the release paper roll is installed on the shaft 511 of the paper feeding tray 51. The release paper is led out from the paper feeding tray 51, guided by the guide wheel 52, and conveyed to the expansion mechanism 2 with appropriate tension and correct direction. Simultaneously, the operator holds the handle 28 to drive the sliding shaft 25 to slide up and down along the support base 23. The sliding block 251 slides directionally along the first sliding groove 231. Through the insertion and cooperation of the sliding block 251 and the connecting groove 221 of the sliding sleeve 22, the sliding sleeve 22 is driven to slide vertically along the support base 23 in sync. When the sliding sleeve 22 moves, the hinge rod 24 swings up and down accordingly, causing the circumferentially evenly distributed expansion plate 21 to contract or expand synchronously. The enclosing diameter is adjusted to wind the release paper. After adjustment, the fixing groove 271 of the fixing plate 27 is inserted into the sliding plate 211 of the expansion plate 21 to lock the position of the expansion plate 21. At the same time, the second sliding groove 261 of the base plate 26 provides horizontal guidance for the sliding plate 211 to ensure the stable movement of the expansion plate 21. When the drive motor 33 starts, the output shaft of the drive motor 33 drives the connecting shaft 32 to rotate. The connecting plate 321 rotates synchronously with the connecting shaft 32, which in turn drives the connecting sleeve 31 to rotate. The connecting sleeve 31 connects with the connecting post 262 of the base plate 26 through the fixing hole 311, and transmits power to the base plate 26, so that the expansion mechanism 2 rotates synchronously with the rotating mechanism 3. The release paper is conveyed to the expansion mechanism 2 through the guide wheel 52 and is wound with the expansion plate 21. After winding, the release paper roll is placed on the receiving tray 4, which is coaxially fixed with the expansion mechanism 2. The forklift is inserted into the receiving slot 41 of the receiving tray 4 to transport the release paper roll, thus completing the entire receiving and unloading process.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
