Description

Technical Field

[0001] The invention relates to the technical field of roller plating equipment, and in particular to an automatic cover opening device for a roller plating line and a roller plating line system. Background Art

[0002] Barrel plating is to place small parts in a special drum. During the rotation of the drum, the parts are constantly rolling and changing positions. Through the small holes on the drum, the plating solution can enter the drum and fully contact the surface of the parts. Under the action of direct current, the metal ions in the plating solution are reduced and deposited on the surface of the parts, thus forming an electroplating layer.

[0003] In the prior art, the traditional roller needs to manually open and close the cover of the roller to load and unload products, which leads to cumbersome operation procedures and low production efficiency. Summary of the invention

[0004] In view of this, the present invention provides an automatic cover opening device for a roller plating line and a roller plating line system to solve the problem that the traditional roller requires manual opening and closing of the roller cover, resulting in low production efficiency.

[0005] In a first aspect, the present invention provides an automatic cover opening device for a barrel plating line drum, comprising:

[0006] The frame is provided with an inner annular groove and an outer annular groove which are coaxially arranged, and a connecting groove is provided between the inner annular groove and the outer annular groove;

[0007] A roller is rotatably arranged on the frame via a rotating shaft, the roller comprises a cylinder body with a receiving cavity and a cover body, an opening is provided on the outer wall of the cylinder body, and a rotatable cover of the cover body is arranged at the opening; a convex portion extending outward is provided on the outer wall of the cylinder body, and a guide groove is provided on the convex portion;

[0008] A guide rod extending along the axial direction of the drum and arranged on the cover body, wherein an end of the guide rod passes through the guide groove and is arranged in the inner annular groove or the outer annular groove;

[0009] A toggle member rotatably disposed in the communicating groove for adjusting the guide rod to switch between the inner annular groove and the outer annular groove;

[0010] A driving mechanism, used for driving the drum to rotate forward or reverse;

[0011] When the roller rotates forward, the guide rod approaches the cylinder and moves along the inner annular groove, and the cover is in a closed state; when the roller switches from forward rotation to reverse rotation, the guide rod switches from the inner annular groove to the outer annular groove via the toggle member so that the guide rod is away from the cylinder, and the cover is in an open state.

[0012] Beneficial effects: When parts need to be electroplated, the automatic opening device of the drum of the drum plating line drives the drum to rotate forward on the frame through the driving mechanism, so that the guide rod is close to the outer wall of the drum, and the end of the guide rod rotates in the inner annular groove, and the cover is in a closed state. During the rotation of the drum, the parts are constantly rolling and changing positions in the accommodating cavity of the drum. Through the small holes on the drum, the plating solution can enter the inside of the drum and fully contact the surface of the parts. Under the action of direct current, the metal ions in the plating solution are reduced and deposited on the surface of the parts, thereby forming an electroplating layer.

[0013] When it is necessary to unload the parts in the drum, the driving mechanism is adjusted from forward rotation to reverse rotation, so that the drum switches from forward rotation to reverse rotation. At this time, the end of the guide rod first rotates along the inner annular groove. When the end of the guide rod reaches the position of the connecting groove, the drum drives the guide rod to rotate in the opposite direction, and the end of the guide rod is adjusted from the inner annular groove to the outer annular groove through the toggle member. At this time, the guide rod is guided by the guide groove, so that the guide rod moves away from the cylinder, and then drives the cover body to rotate on the cylinder, so that the cover body switches from the closed state to the open state. When the drum rotates so that the opening on the cylinder faces the bottom, the parts in the cavity of the cylinder are automatically unloaded from the opening, completing the unloading of the parts.

[0014] In summary, by adjusting the rotation direction of the drum, the cover can be switched on and off. On the one hand, when rotating in the forward direction, the cover is in a closed state, providing a stable roller plating environment for the parts and ensuring the quality of electroplating; on the other hand, when rotating in the reverse direction, the cover switches from a closed state to an open state, completing the automatic unloading of the parts in the drum. The operation is simple and improves the production efficiency of roller plating.

[0015] In an optional embodiment, the toggle member includes an overlapping section and a switching section connected to the overlapping section, the overlapping section is located in the outer annular groove, the switching section is located in the inner annular groove, and the connection between the overlapping section and the switching section is rotatably disposed in the connecting groove via a rotating member;

[0016] When the guide rod is not in contact with the toggle member, the bottom wall of the switching section abuts against the inner groove wall of the inner annular groove, and the top wall of the overlapping section abuts against the outer groove wall of the outer annular groove.

[0017] Beneficial effect: The overlapping section of the toggle member is located in the outer annular groove, and the switching section is located in the inner annular groove. When the drum switches from forward rotation to reverse rotation, and the end of the guide rod moves to the connecting groove position, the bottom wall of the switching section abuts against the inner groove wall of the inner annular groove, guiding the guide rod to move to the switching section. At this time, the guide rod continues to rotate in the opposite direction, so that the guide rod moves to the overlapping section, and then presses down the toggle member to rotate, so that the guide rod smoothly transitions to the outer annular groove. Ensure that the guide rod can smoothly switch from the inner annular groove to the outer annular groove, avoid the guide rod from being stuck or abnormally jumping due to mechanical interference and trajectory deviation, and ensure smooth opening and closing of the cover.

[0018] In an optional embodiment, the bottom wall of the switching section is provided with a first inclined surface, and when the guide rod is not in contact with the toggle member, the first inclined surface is inclined toward the inner ring groove wall close to the inner annular groove along the positive rotation direction of the drum.

[0019] Beneficial effect: When the drum rotates in the positive direction, the guide rod moves in the inner annular groove and is about to contact the toggle member, the existence of the first inclined surface enables the guide rod to contact the toggle member more gently. Since the first inclined surface is inclined toward the inner ring groove wall close to the inner annular groove, the guide rod will gradually approach the toggle member along the first inclined surface during the process of moving along the positive rotation direction of the drum, thereby pushing the toggle member to rotate, so that the guide rod smoothly passes the position of the toggle member and continues to rotate in the inner annular groove, effectively reducing the collision impact force generated at the moment when the guide rod contacts the toggle member, and avoiding component damage that may be caused by strong collision, such as deformation of the guide rod and displacement of the toggle member.

[0020] Since the first inclined surface can make the guide rod contact and transition smoothly, hard collision and friction between parts are reduced. During the long-term operation of the barrel plating equipment, the degree of wear of the contact part between the guide rod and the toggle piece can be significantly reduced. Compared with the absence of the first inclined surface, the direct collision of the guide rod with the toggle piece may cause local wear at the contact point, while the buffering and guiding effect of the first inclined surface can disperse the contact force, making the wear more uniform and extending the service life of the guide rod and the toggle piece.

[0021] In an optional embodiment, the top wall of the switching section is provided with a second inclined surface, and when the guide rod is not in contact with the toggle member, the second inclined surface gradually inclines toward the inner ring groove wall close to the inner annular groove along the positive rotation direction of the drum.

[0022] Beneficial effect: When the drum rotates in the reverse direction, the guide rod moves from the inner annular groove to the connecting groove and is about to contact the toggle member, the second inclined surface can play a guiding role. Since the second inclined surface gradually inclines toward the inner ring groove wall close to the inner annular groove along the forward rotation direction of the drum, the guide rod can smoothly switch from the inner annular groove to the outer annular groove through the second inclined surface when rotating in the reverse direction, avoiding the hard collision between the guide rod and the toggle member.

[0023] During the contact between the guide rod and the toggle member, the second inclined surface makes the contact more stable, which helps to reduce the vibration of the entire device during operation. At the same time, the stable contact can also reduce the noise during operation and create a relatively quiet working environment.

[0024] In an optional embodiment, a first magnetic attraction component is provided on the bottom wall of the switching section, and a second magnetic attraction component which is attracted to the first magnetic attraction component is provided on the inner groove wall of the inner annular groove.

[0025] Beneficial effect: Since the second magnetic member and the first magnetic member are attracted to each other, when the guide rod and the toggle member are not in contact, the second magnetic member and the first magnetic member are attracted to each other, so that the bottom wall of the switching section abuts against the inner groove wall of the inner annular groove. If the guide rod contacts the toggle member during the rotation process, causing the toggle member to rotate, at this time, the bottom wall of the switching section of the toggle member is separated from the inner groove wall of the inner annular groove. When the guide rod is separated from the toggle member, under the action of the mutual attraction between the first magnetic member and the second magnetic member, the bottom wall of the switching section abuts against the inner groove wall of the inner annular groove.

[0026] In an optional embodiment, the ring widths of the inner annular groove and the outer annular groove are adapted to the end diameter of the guide rod.

[0027] Beneficial effect: When the ring width of the inner annular groove and the outer annular groove is matched with the diameter of the end of the guide rod, the movement trajectory of the guide rod can be accurately restricted. During the forward rotation of the drum, the end of the guide rod moves in the inner annular groove. The adapted ring width can prevent the guide rod from shaking left and right or jumping up and down in the groove, so that the guide rod always remains in the correct position, thereby ensuring that the cover can be stably in a closed state, providing a stable environment for the roller plating process of the parts.

[0028] When the drum rotates in the opposite direction and the guide rod needs to switch from the inner annular groove to the outer annular groove, the appropriate ring width helps to accurately guide this action. The guide rod can accurately move along the connecting groove and smoothly enter the outer annular groove, avoiding excessive position deviation of the guide rod when entering the outer annular groove due to the ring width being too wide, thereby affecting the accuracy of the cover opening action.

[0029] In an optional embodiment, the guide groove is an arc-shaped groove, and the notch of the arc-shaped groove is oriented in the same direction as the forward rotation direction of the drum.

[0030] Beneficial effect: The arc groove notch of the guide groove is oriented in the same direction as the positive rotation direction of the drum, so that the guide rod can better follow the rotational movement of the drum during the positive rotation of the drum. When the drum switches from positive rotation to reverse rotation, when the guide rod rotates in the reverse direction to the position of the toggle member, the guide rod is pushed by the toggle member to move away from the outer wall of the drum. In this process, since the notch of the arc groove is oriented in the same direction as the positive rotation direction of the drum, the guide rod moves along the arc direction of the guide groove under the restriction of the guide groove, so that the guide rod drives the cover body to rotate relative to the drum body, and then the cover body rotates relative to the drum body to complete the opening of the cover body.

[0031] In an optional embodiment, it also includes a support shaft, wherein the support shaft and the rotating shaft are respectively arranged at two ends of the cylinder, and the cylinder is rotatably arranged on the support shaft. A through hole connecting the accommodating cavity with the outside is opened on the support shaft, and the through hole is inclined toward the bottom of the accommodating cavity. The through hole is used for allowing the conductive wire to penetrate into the bottom of the accommodating cavity from the outside.

[0032] Beneficial effects: During the barrel plating process, the uniformity of electrical conduction is crucial to the quality of electroplating of parts. By opening a through hole connecting the accommodating cavity with the outside world on the support shaft, and tilting the through hole toward the bottom of the accommodating cavity, it is convenient for the conductive wire to penetrate the bottom of the drum from the outside world, and the current can be better guided to the bottom area of ​​the drum where the parts are concentrated, ensuring that the parts at the bottom can also obtain sufficient and uniform current, so that the metal ions in the plating solution are evenly deposited on the surface of the parts, thereby improving the uniformity and quality of the electroplating layer of the parts in the entire drum.

[0033] In an optional embodiment, the driving mechanism includes a driving member and a gear set, and the rotating shaft is connected to the driving member via the gear set.

[0034] Beneficial effects: The rotating shaft is driven by the cooperation of the driving member and the gear set, which can realize the precise control of the drum speed. The gear set can be designed according to different transmission ratios to flexibly adjust the drum speed. In the case of fine electroplating treatment and high requirements on the surface coating quality of parts, the transmission ratio of the gear set can be adjusted to reduce the drum speed, so that the parts roll more slowly and evenly in the drum, thereby ensuring that the metal ions in the plating solution can be more evenly deposited on the surface of the parts, effectively improving the quality of roller plating.

[0035] During the barrel plating process, it is necessary to accurately control the forward and reverse rotation of the barrel to achieve the automatic cover opening and closing functions, as well as the normal barrel plating and unloading of parts. The gear set can achieve bidirectional transmission, change the power output direction through the drive element, and accurately control the forward and reverse rotation of the barrel.

[0036] In a second aspect, the present invention further provides a roller plating line system, including an automatic cover opening device for the roller of the roller plating line.

[0037] Beneficial effects: This barrel plating line system can realize the opening and closing switching of the cover by adjusting the rotation direction of the barrel. On the one hand, the cover is in a closed state when rotating in the forward direction, providing a stable barrel plating environment for the parts and ensuring the electroplating quality; on the other hand, the reverse rotation makes the cover switch from the closed state to the open state, completing the automatic unloading of the parts in the barrel. The operation is simple and improves the production efficiency of barrel plating. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0048] In the related art, the traditional roller needs to manually open and close the cover of the roller to load and unload products, which leads to cumbersome operation procedures and low production efficiency.

[0049] In order to solve the above technical problems, the following Figures 1 to 6 , describing an embodiment of the present invention.

[0050] According to an embodiment of the present invention, on the one hand, Figures 1 to 6 As shown, an automatic opening device for a roller plating line drum is provided, comprising a frame 1, a roller 2, a guide rod 204, a toggle member 3 and a driving mechanism 4.

[0051] Specifically, Figures 1 to 4 As shown, the frame 1 is provided with an inner annular groove 101 and an outer annular groove 102, wherein the inner annular groove 101 and the outer annular groove 102 are coaxially arranged. A connecting groove 103 is provided between the inner annular groove 101 and the outer annular groove 102 on the frame 1, and the inner annular groove 101 and the outer annular groove 102 are connected through the connecting groove 103.

[0052] Specifically, Figures 1 to 4 As shown, the drum 2 is rotatably arranged on the frame 1 via the rotating shaft 201. The drum 2 includes a cylinder 202 and a cover 203, wherein a receiving cavity (not shown in the figure) is reserved in the cylinder 202, and an opening is provided on the outer wall of the cylinder 202. The cover 203 is rotatably arranged at the opening. A protrusion 2021 extending outward is provided on the outer wall of the cylinder 202, and a guide groove 20211 is provided on the protrusion 2021.

[0053] Specifically, Figure 2As shown, the guide rod 204 extends along the axial direction of the drum 2, and the guide rod 204 is arranged on the cover body 203. The end of the guide rod 204 passes through the guide groove 20211 and is arranged in the inner annular groove 101 or the outer annular groove 102.

[0054] Specifically, Figure 4 As shown, the toggle member 3 is rotatably disposed in the connecting groove 103 , and the toggle member 3 is used to adjust the guide rod 204 to switch between the inner annular groove 101 and the outer annular groove 102 .

[0055] Specifically, Figure 3 As shown, the driving mechanism 4 is used to drive the drum 2 to rotate forward or reverse.

[0056] Specifically, Figure 4 As shown, when the drum 2 is rotating in the forward direction, the guide rod 204 is close to the outer wall of the cylinder 202 and moves along the inner annular groove 101, and the cover 203 is in a closed state; Figure 6 As shown, when the drum 2 switches from forward rotation to reverse rotation, the guide rod 204 is adjusted by the shifting member 3 to switch from the inner annular groove 101 to the outer annular groove 102, so that the guide rod 204 is away from the outer wall of the cylinder 202, and the cover 203 is in an open state.

[0057] In this automatic opening device for the drum of the drum plating line, when it is necessary to electroplate the parts, the driving mechanism 4 drives the drum 2 to rotate forward on the frame 1, so that the guide rod 204 is close to the outer wall of the drum 2, and the end of the guide rod 204 rotates in the inner annular groove 101, and the cover 203 is in a closed state. During the rotation of the drum 2, the parts are constantly rolling and shifting in the accommodating cavity of the drum 2. Through the small holes on the drum 2, the plating solution can enter the inside of the drum 2 and fully contact the surface of the parts. Under the action of direct current, the metal ions in the plating solution are reduced and deposited on the surface of the parts, thereby forming an electroplating layer.

[0058] When it is necessary to unload the parts in the drum 2, the driving mechanism 4 is adjusted from forward rotation to reverse rotation, so that the drum 2 switches from forward rotation to reverse rotation. At this time, the end of the guide rod 204 first rotates along the inner annular groove 101. When the end of the guide rod 204 reaches the position of the connecting groove 103, the drum 2 drives the guide rod 204 to rotate in the reverse direction. The end of the guide rod 204 is adjusted from the inner annular groove 101 to the outer annular groove 102 through the toggle member 3. At this time, the guide rod 204 is guided by the guide groove 20211, so that the guide rod 204 moves away from the cylinder 202, and then drives the cover 203 to rotate on the cylinder 202, so that the cover 203 switches from the closed state to the open state. When the drum 2 rotates so that the opening on the cylinder 202 faces the bottom, the parts in the cavity of the cylinder 202 are automatically unloaded from the opening, completing the unloading of the parts.

[0059] In summary, by adjusting the rotation direction of the drum 2, the cover 203 can be switched on and off. On the one hand, when rotating in the forward direction, the cover 203 is in a closed state, providing a stable roller plating environment for the parts and ensuring the electroplating quality; on the other hand, when rotating in the reverse direction, the cover 203 switches from a closed state to an open state, completing the automatic unloading of the parts in the drum 2. The operation is simple and the production efficiency of roller plating is improved.

[0060] It should be noted that Figure 4 Taking the perspective as an example, the positive rotation of the drum 2 means that the drum 2 rotates clockwise, and the reverse rotation of the drum 2 means that the drum 2 rotates counterclockwise.

[0061] Specifically, the rack 1 can be set in any existing shape, for example, the rack 1 can be set as a "U"-shaped bracket. In the embodiment of the present application, the shape of the rack 1 is not specifically limited.

[0062] Specifically, the connecting groove 103 is used to connect the inner annular groove 101 and the outer annular groove 102, so that the guide rod 204 can switch between the inner annular groove 101 and the outer annular groove 102. In the embodiment of the present application, the shape of the connecting groove 103 is not specifically limited.

[0063] Specifically, the opening can be set to any existing shape such as a rectangle, a circle, etc. In the embodiment of the present application, the shape of the opening is not specifically limited.

[0064] Specifically, the toggle member 3 can be configured as a shuttle-shaped member to ensure smooth movement of the guide rod 204 when adjusting the position of the guide rod 204. In the embodiment of the present application, the structure of the toggle member 3 is not specifically limited.

[0065] Specifically, the driving mechanism 4 can be any existing driving mechanism 4. For example, the driving mechanism 4 can be gear driven, conveyor belt driven, chain driven, etc. In the embodiment of the present application, the type of the driving mechanism 4 is not specifically limited.

[0066] In one embodiment, Figure 4 and Figure 5 As shown, the toggle member 3 includes an overlap section 301 and a switching section 302 connected to the overlap section 301. The overlap section 301 is located in the outer annular groove 102, and the switching section 302 is located in the inner annular groove 101. The connection between the overlap section 301 and the switching section 302 is rotatably arranged in the connecting groove 103 via the rotating member 5.

[0067] When the guide rod 204 is not in contact with the toggle member 3 , the bottom wall of the switching section 302 abuts against the inner groove wall of the inner annular groove 101 , and the top wall of the overlapping section 301 abuts against the outer groove wall of the outer annular groove 102 .

[0068] The overlapping section 301 of the toggle member 3 is located in the outer annular groove 102, and the switching section 302 is located in the inner annular groove 101. When the drum 2 switches from forward rotation to reverse rotation, and the end of the guide rod 204 moves to the position of the connecting groove 103, the bottom wall of the switching section 302 abuts against the inner groove wall of the inner annular groove 101, guiding the guide rod 204 to move to the switching section 302. At this time, the guide rod 204 continues to rotate in the reverse direction, so that the guide rod 204 moves to the overlapping section 301, and then presses the toggle member 3 downward to rotate, so that the guide rod 204 smoothly transitions to the outer annular groove 102. Ensure that the guide rod 204 can smoothly switch from the inner annular groove 101 to the outer annular groove 102, avoid the guide rod 204 from being stuck or abnormally jumping due to mechanical interference and trajectory deviation, and ensure the smooth opening and closing of the cover 203.

[0069] In one embodiment, Figure 4 and Figure 5 As shown, the bottom wall of the switching section 302 is provided with a first inclined surface 3021 , and when the guide rod 204 is not in contact with the toggle member 3 , along the positive rotation direction of the drum 2 , the first inclined surface 3021 is inclined toward the inner ring groove wall close to the inner annular groove 101 .

[0070] When the drum 2 rotates in the forward direction, the guide rod 204 moves in the inner annular groove 101 and is about to contact the toggle member 3, the existence of the first inclined surface 3021 enables the guide rod 204 to contact the toggle member 3 more gently. Since the first inclined surface 3021 is inclined toward the inner groove wall close to the inner annular groove 101, the guide rod 204 will gradually approach the toggle member 3 along the first inclined surface 3021 during the process of moving along the forward rotation direction of the drum 2, thereby pushing the toggle member 3 to rotate, so that the guide rod 204 smoothly passes the position of the toggle member 3 and continues to rotate in the inner annular groove 101, effectively reducing the collision impact force generated when the guide rod 204 contacts the toggle member 3, and avoiding component damage that may be caused by strong collision, such as deformation of the guide rod 204 and displacement of the toggle member 3.

[0071] Since the first inclined surface 3021 can make the guide rod 204 contact and transition smoothly, hard collision and friction between components are reduced. During the long-term operation of the roller plating equipment, the degree of wear of the contact part between the guide rod 204 and the toggle member 3 can be significantly reduced. Compared with the absence of the first inclined surface 3021, the direct collision of the guide rod 204 with the toggle member 3 may cause local wear at the contact point, while the buffering and guiding effect of the first inclined surface 3021 can disperse the contact force, making the wear more uniform, and extending the service life of the guide rod 204 and the toggle member 3.

[0072] In one embodiment, Figure 4 and Figure 5As shown, the top wall of the switching section 302 is provided with a second inclined surface 3022. When the guide rod 204 is not in contact with the toggle member 3, the second inclined surface 3022 gradually approaches the inner ring groove wall direction of the inner annular groove 101 along the positive rotation direction of the drum 2.

[0073] When the drum 2 rotates in the reverse direction, the guide rod 204 moves from the inner annular groove 101 to the connecting groove 103 and is about to contact the toggle member 3, the second inclined surface 3022 can play a guiding role. Since the second inclined surface 3022 gradually inclines toward the inner ring groove wall close to the inner annular groove 101 along the forward rotation direction of the drum 2, the guide rod 204 can smoothly switch from the inner annular groove 101 to the outer annular groove 102 through the second inclined surface 3022 when rotating in the reverse direction, avoiding a hard collision between the guide rod 204 and the toggle member 3.

[0074] During the contact between the guide rod 204 and the toggle member 3, the second inclined surface 3022 makes the contact more stable, which helps to reduce the vibration of the entire device during operation. At the same time, the stable contact can also reduce the noise during operation and create a relatively quiet working environment.

[0075] By reducing the impact force and vibration when the guide rod 204 contacts the toggle member 3, the second inclined surface 3022 can effectively reduce the friction and wear between the components. In the long-term use process, the service life of the guide rod 204 and the toggle member 3 can be significantly extended, and the maintenance and replacement frequency of the equipment can be reduced.

[0076] In one embodiment, Figure 4 and Figure 5 As shown, a first magnetic attraction member is disposed on the bottom wall of the switching section 302 , and a second magnetic attraction member is disposed on the inner groove wall of the inner annular groove 101 , and the second magnetic attraction member is disposed to attract the first magnetic attraction member.

[0077] Since the second magnetic member is attracted to the first magnetic member, when the guide rod 204 is not in contact with the toggle member 3, the second magnetic member is attracted to the first magnetic member, so the bottom wall of the switching section 302 is in contact with the inner groove wall of the inner annular groove 101. If the guide rod 204 contacts the toggle member 3 during the rotation process, the toggle member 3 rotates, and the bottom wall of the switching section 302 of the toggle member 3 is separated from the inner groove wall of the inner annular groove 101. After the guide rod 204 is separated from the toggle member 3, the bottom wall of the switching section 302 is in contact with the inner groove wall of the inner annular groove 101 under the mutual attraction between the first magnetic member and the second magnetic member.

[0078] In one embodiment, Figure 4 As shown, the ring widths of the inner annular groove 101 and the outer annular groove 102 match the diameter of the end of the guide rod 204 .

[0079] When the ring widths of the inner annular groove 101 and the outer annular groove 102 are matched with the diameter of the end of the guide rod 204, the movement trajectory of the guide rod 204 can be accurately restricted. During the forward rotation of the drum 2, the end of the guide rod 204 moves in the inner annular groove 101, and the matched ring width can prevent the guide rod 204 from shaking left and right or jumping up and down in the groove, so that the guide rod 204 always remains in the correct position, thereby ensuring that the cover body 203 can be stably in a closed state, providing a stable environment for the roller plating process of the parts.

[0080] When the drum 2 rotates in the reverse direction and the guide rod 204 needs to switch from the inner annular groove 101 to the outer annular groove 102, the adapted ring width helps to accurately guide this action. The guide rod 204 can accurately move along the connecting groove 103 and smoothly enter the outer annular groove 102, avoiding the excessive position deviation of the guide rod 204 when entering the outer annular groove 102 due to the excessive ring width, thereby affecting the accuracy of the opening action of the cover 203.

[0081] In one embodiment, Figure 2 As shown, the guide groove 20211 is an arc-shaped groove, and the notch of the arc-shaped groove is oriented in the same direction as the positive rotation direction of the drum 2.

[0082] The arc groove notch of the guide groove 20211 is oriented in the same direction as the forward rotation direction of the drum 2, so that the guide rod 204 can better follow the rotational movement of the drum 2 during the forward rotation of the drum 2. When the drum 2 switches from forward rotation to reverse rotation, when the guide rod 204 reversely rotates to the position of the toggle member 3, the guide rod 204 is pushed by the toggle member 3 to move away from the outer wall of the cylinder 202. In this process, since the notch of the arc groove is oriented in the same direction as the forward rotation direction of the drum 2, the guide rod 204 moves along the arc direction of the guide groove 20211 under the restriction of the guide groove 20211, so that the guide rod 204 drives the cover 203 to rotate relative to the cylinder 202, and then the cover 203 rotates relative to the cylinder 202 to complete the opening of the cover 203.

[0083] In one embodiment, Figure 3 As shown, the housing 202 further includes a support shaft 6, the support shaft 6 and the rotating shaft 201 are respectively arranged at both ends of the cylinder 202, and the cylinder 202 is rotatably arranged on the support shaft 6. A through hole 601 is provided on the support shaft 6, and the accommodating cavity is connected with the outside through the through hole 601. Among them, the through hole 601 is inclined toward the bottom of the accommodating cavity, and is used for the conductive wire to penetrate into the bottom of the accommodating cavity from the outside.

[0084] In the barrel plating process, the uniformity of electrical conduction is crucial to the quality of electroplating of parts. By opening a through hole 601 connecting the accommodating cavity with the outside world on the support shaft 6, and making the through hole 601 inclined toward the bottom of the accommodating cavity, it is convenient for the conductive wire to penetrate the bottom of the drum 2 from the outside world, and the current can be better guided to the bottom area of ​​the drum 2 where the parts are concentrated, ensuring that the parts at the bottom can also obtain sufficient and uniform current, so that the metal ions in the plating solution are evenly deposited on the surface of the parts, thereby improving the uniformity and quality of the electroplating layer of the parts in the entire drum 2.

[0085] In one embodiment, Figure 3 As shown, the driving mechanism 4 includes a driving member 401 and a gear set 402 , and the rotating shaft 201 is connected to the driving member 401 via the gear set 402 .

[0086] The rotation shaft 201 is driven by the cooperation of the driving member 401 and the gear set 402, so that the rotation speed of the drum 2 can be precisely controlled. The gear set 402 can be designed according to different transmission ratios to flexibly adjust the rotation speed of the drum 2. When fine electroplating is required and the surface coating quality of the parts is required to be high, the rotation speed of the drum 2 can be reduced by adjusting the transmission ratio of the gear set 402, so that the parts can roll more slowly and evenly in the drum 2, thereby ensuring that the metal ions in the plating solution can be more evenly deposited on the surface of the parts, effectively improving the quality of the roll plating.

[0087] During the barrel plating process, it is necessary to accurately control the forward and reverse rotation of the barrel 2 to realize the automatic cover opening and closing functions, as well as the normal barrel plating and unloading of parts. The gear set 402 can realize bidirectional transmission, change the power output direction through the driving member 401, and accurately control the forward and reverse rotation of the barrel 2.

[0088] Specifically, the driving component 401 can be an AC motor, a servo motor, a hydraulic motor, etc. In the embodiment of the present application, there is no specific limitation on the type of the driving component 401.

[0089] The working principle of the automatic opening device of the barrel plating line drum in this embodiment is described as follows:

[0090] 1. Roller 2 rotates forward (electroplating process):

[0091] The driving member 401 in the driving mechanism 4 transmits power to the rotating shaft 201 of the drum 2 through the gear set 402. The gear set 402 plays a role in adjusting the rotation speed and torque to ensure that the drum 2 rotates in the forward direction at a suitable speed.

[0092] When the drum 2 rotates, the end of the guide rod 204 mounted on the cover 203 is guided by the guide groove 20211. Since the guide groove 20211 is an arc groove and the notch is oriented in the same direction as the positive rotation direction of the drum 2, the guide rod 204 will naturally approach the outer wall of the drum 2. At the same time, the end of the guide rod 204 rotates in the inner annular groove 101. The ring width of the inner annular groove 101 is matched with the diameter of the end of the guide rod 204, which accurately limits the position of the guide rod 204, so that the guide rod 204 can be closely attached to the outer wall of the drum 2, thereby keeping the cover 203 in a closed state.

[0093] During the forward rotation of the drum 2, the parts are constantly rolling and changing positions in the receiving cavity of the drum 2. The small holes on the outer wall of the drum 2 allow the plating solution to enter the drum 2 and fully contact the surface of the parts. Under the action of direct current, the conductive wire is introduced into the bottom of the drum 2 through the through hole 601 obliquely arranged on the support shaft 6, so that the metal ions in the plating solution are reduced and deposited on the surface of the parts, thereby forming an electroplating layer.

[0094] 1. Drum 2 rotates in the opposite direction (unloading process):

[0095] When unloading is required, the driving mechanism 4 switches the drum 2 from forward rotation to reverse rotation. At this time, the end of the guide rod 204 first rotates along the inner annular groove 101. When the end of the guide rod 204 reaches the position of the connecting groove 103, due to the reverse rotation of the drum 2, the guide rod 204 contacts the toggle member 3, and the toggle member 3 adjusts the end of the guide rod 204 from the inner annular groove 101 to the outer annular groove 102.

[0096] After the guide rod 204 enters the outer annular groove 102, under the guidance of the guide groove 20211, the guide rod 204 moves away from the cylinder 202, thereby driving the cover 203 to rotate on the cylinder 202, so that the cover 203 switches from the closed state to the open state. As the drum 2 continues to rotate in the opposite direction, when the opening on the cylinder 202 faces the bottom, the parts in the cavity of the cylinder 202 are automatically unloaded from the opening, completing the unloading process of the parts.

[0097] According to an embodiment of the present invention, on the other hand, a roller plating line system is provided, including an automatic cover opening device for a roller of the roller plating line.

[0098] This barrel plating line system can realize the opening and closing switching of the cover 203 by adjusting the rotation direction of the barrel 2. On the one hand, when the cover 203 rotates in the forward direction, it is in a closed state, providing a stable barrel plating environment for the parts and ensuring the electroplating quality; on the other hand, when the cover 203 rotates in the reverse direction, it switches from the closed state to the open state, completing the automatic unloading of the parts in the barrel 2. The operation is simple and the production efficiency of barrel plating is improved.

[0099] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
