Description

Technical Field

[0001] This utility model relates to the field of electroplating rack technology, specifically an electroplating rack that can flexibly arrange workpieces. Background Technology

[0002] Rack plating, also known as hanging plating, is an electroplating process in which workpieces are suspended on a highly conductive rack and immersed in an electroplating solution as cathodes. Metal ions are deposited on the surface of the parts by passing an electric current through the rack. In existing technologies, electroplating racks are used to place the workpieces to be electroplated. However, the existing electroplating racks have a fixed shape. When the workpieces to be electroplated are of different shapes and sizes, they may not fit properly, and the workpieces may become unstable and fall off the electroplating rack. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide an electroplating rack that can flexibly arrange workpieces. By selectively installing workpiece support shelves, it can be adjusted to adapt to different workpieces, ensuring that the workpieces are stably suspended on the electroplating rack. The height of the main body of the electroplating rack in the electroplating tank can be adjusted by the rack lifting mechanism to ensure that the workpieces are completely immersed in the electroplating solution, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an electroplating rack that allows for flexible arrangement of workpieces, comprising an electroplating rack body, the electroplating rack body including a top beam, uprights, and a bottom beam, wherein two uprights are provided and arranged parallel to each other, the tops of the two uprights are fixedly connected by horizontally distributed top beams, and the bottoms of the two uprights are fixedly connected by horizontally distributed bottom beams, further comprising:

[0005] The shelving installation mechanism is installed at equal intervals on the front side of the columns;

[0006] The workpiece support shelf is connected at both ends to two corresponding shelf mounting mechanisms on the left and right sides, respectively.

[0007] The hanging bracket lifting mechanism is installed on the top of the column, and a hanging mechanism is installed on the top of the hanging bracket lifting mechanism.

[0008] The top beam, columns, and bottom beam form the rectangular electroplating rack body. The hanging mechanism hangs on the plating rack, thus installing the electroplating rack body. The shelf mounting mechanism is used to detachably install workpiece support shelves. The number of workpiece support shelves can be selected according to different workpieces. Workpieces are suspended on the workpiece support shelves. The rack lifting mechanism can control the distance between the electroplating rack body and the hanging mechanism, thereby changing the height of the electroplating rack body in the electroplating tank. The lifting of the electroplating rack body can be controlled as needed to ensure that the workpieces on the workpiece support shelves are completely immersed in the electroplating solution.

[0009] Furthermore, the shelf mounting mechanism includes shelf support rods, mounting nuts, clamping studs, and a rotating rod. Multiple L-shaped shelf support rods are vertically and equidistantly arranged on the front side of each column. A mounting nut is fixedly connected to the middle of the vertical portion of each shelf support rod. Each mounting nut is threadedly connected to a longitudinal clamping stud. The front end of each clamping stud is fixedly connected to the middle of the rotating rod. The shelf support rods support the end of the workpiece-supporting shelf. The mounting nuts are used to install the clamping studs. The rotating rod allows the clamping studs to be rotated, pressing them against the end of the workpiece-supporting shelf, thus completing the detachable installation of the workpiece-supporting shelf. Since each column has multiple L-shaped shelf support rods, the number and spacing of the workpiece-supporting shelves can be selected as needed.

[0010] Furthermore, the shelf mounting mechanism also includes padding protrusions, and padding protrusions are respectively provided on the front side of the shelf support rod corresponding to the positions of each tightening stud.

[0011] Furthermore, the workpiece support shelf includes a shelf beam, disassembly sleeves, a workpiece support assembly, and support plates. Two support plates are fixedly connected to each of the left and right ends of the shelf beam, and each support plate is placed into a corresponding shelf support rod. Multiple disassembly sleeves are fixedly connected laterally at equal intervals on the front and rear sides of the shelf beam. A workpiece support assembly is installed at the end of each disassembly sleeve. The support plates at the ends of the shelf beam are placed inside the shelf support rods. A clockwise rotation of a screw rod causes the tightening stud to move backward relative to the mounting nut, pressing the support plate against the front side of the gasket protrusion. The support plates thus fix the shelf beam. The disassembly sleeves are used to install the workpiece support assembly, which is used to directly suspend the workpiece.

[0012] Furthermore, the workpiece support assembly includes a bent column, a U-shaped column, and a longitudinal column. The inner side of the end of each detachable longitudinal sleeve is fixedly sleeved with one end of the bent column. The other end of the bent column is integrally formed and connected to one end of the U-shaped column. The other end of the U-shaped column is integrally formed and connected to the longitudinal column.

[0013] Furthermore, the hanging bracket lifting mechanism includes a pull rod, a control panel, a lead screw nut, a fixed frame, a vertical slot, a lifting lead screw, and a knob. The top of each column is fixedly connected to the bottom end of the pull rod, and the rear side of the top of the pull rod is fixedly connected to the front side of the control panel. The middle part of the control panel is fixedly connected to the lead screw nut. The fixed frame is rotatably connected to the vertical lifting lead screw through a bearing. The lifting lead screw and the lead screw nut are connected in cooperation. The top of the lifting lead screw is fixedly connected to the middle part of the knob. The inner side of the fixed frame is provided with a vertical slot, which is vertically slidably connected to the protrusion on the rear side of the control panel. Rotating the lifting screw clockwise with the knob causes the control plate to move downwards along the vertical groove due to the thread action between the lifting screw and the screw nut. This allows the column to move downwards relative to the fixed frame and the hanging mechanism via the pull rod, thus allowing the main body of the electroplating rack to move downwards within the electroplating tank. Rotating the lifting screw counterclockwise with the knob causes the control plate to move upwards along the vertical groove due to the thread action between the lifting screw and the screw nut. This allows the column to move upwards relative to the fixed frame and the hanging mechanism via the pull rod, thus allowing the main body of the electroplating rack to move upwards within the electroplating tank, changing the relative height of the main body of the electroplating rack in the electroplating solution within the electroplating tank.

[0014] Furthermore, the hanging mechanism includes a fixed base and an inverted U-shaped rigid hook. The fixed base is fixedly connected to the rear side of each fixed frame, and the bottom front side of the inverted U-shaped rigid hook is fixedly connected to the top front side of the fixed base.

[0015] Furthermore, the hanging mechanism also includes an inverted U-shaped elastic hook and an arc-shaped guide portion. The front bottom of the inverted U-shaped elastic hook is fixedly connected to the top rear side of the fixing base. The inverted U-shaped elastic hook is located inside the inverted U-shaped rigid hook, and the rear bottom of the inverted U-shaped elastic hook is bent backward to form an arc-shaped guide portion. Since the inverted U-shaped rigid hook is rigid, it is easy for it to sway relative to the plating bracket when hung on it. Therefore, an inverted U-shaped elastic hook is added. The inverted U-shaped elastic hook can deform, and with the guidance of the arc-shaped guide portion, it hangs on the plating bracket. The arc-shaped guide portion guides the inverted U-shaped elastic hook to gradually open, and the elastic deformation of the inverted U-shaped elastic hook allows the inner side of the inverted U-shaped elastic hook to be tightly attached to the plating bracket, which can meet the dual requirements of stable suspension and sufficient contact conductivity.

[0016] Furthermore, it also includes a support mechanism, with two support mechanisms detachably installed at each end of the bottom beam.

[0017] Compared with existing technologies, the advantages of this electroplating rack, which allows for flexible arrangement of workpieces, are:

[0018] 1. The shelf mounting mechanism is used for detachable workpiece support shelves. The number of workpiece support shelves can be selected according to different workpieces. Workpieces are suspended on the workpiece support shelves. The hanging frame lifting mechanism can control the distance between the electroplating rack body and the hanging mechanism, thereby changing the height of the electroplating rack body in the electroplating tank. The lifting of the electroplating rack body can be controlled as needed to ensure that the workpieces on the workpiece support shelves are completely immersed in the electroplating solution.

[0019] 2. The support plate at the end of the shelf beam is placed inside the shelf support rod. By rotating the screw clockwise with the screw rod, the screw rod moves backward relative to the mounting nut. The screw rod presses the support plate against the front side of the liner protrusion. The support plate is used to fix the shelf beam. The longitudinal sleeve is removed to install the workpiece support assembly. The workpiece support assembly is used to directly suspend the workpiece.

[0020] 3. By selectively installing workpiece support racks, it can be adjusted to adapt to different workpieces, with good adaptability and high flexibility. It ensures that the workpieces are stably suspended on the electroplating rack. The height of the main body of the electroplating rack in the electroplating tank can be adjusted by the rack lifting mechanism to ensure that the workpieces are completely immersed in the electroplating solution.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1, please refer to Figures 1 to 3 The present invention provides a technical solution: an electroplating rack that can flexibly arrange workpieces, including an electroplating rack body 1, the electroplating rack body 1 including a top beam 11, a column 12 and a bottom beam 13, the column 12 is provided in two parallel arrangement, the top of the two columns 12 is fixedly connected by the horizontally distributed top beam 11, the bottom of the two columns 12 is fixedly connected by the horizontally distributed bottom beam 13, and also includes a shelf installation mechanism 2, a workpiece supporting shelf 3 and a rack lifting mechanism 4;

[0027] The shelf mounting mechanism 2 is installed at equal intervals on the front side of the column 12.

[0028] The shelf mounting mechanism 2 includes shelf support rods 21, mounting nuts 22, clamping studs 23, and rotating rods 24. Each column 12 has multiple L-shaped shelf support rods 21 arranged vertically at equal intervals on its front side. The number of shelf support rods 21 on the column 12 can be selected as needed. The shelf support rods 21 on two columns 12 are arranged left and right in sequence from top to bottom. The middle part of the vertical part of each shelf support rod 21 is fixedly connected to the mounting nut 22. Each mounting nut 22 is threadedly connected to the longitudinal clamping stud 23. The front end of each clamping stud 23 is fixedly connected to the middle part of the rotating rod 24. The shelf support rod 21 is used to support the end of the workpiece support shelf 3. The mounting nut 22 is used to install the clamping stud 23. With the help of the rotating rod 24, the clamping stud 23 can be rotated to clamp the end of the workpiece support shelf 3, thus completing the detachable installation of the workpiece support shelf 3. Since each column 12 has multiple L-shaped shelf support rods 21, the number and spacing of the workpiece support shelf 3 can be selected as needed.

[0029] The shelf mounting mechanism 2 also includes padding protrusions 25. Padding protrusions 25 are respectively provided on the front side of the shelf support rod 21 corresponding to the positions of each clamping stud 23. The padding protrusions 25 enable the clamping stud 23 to more stably clamp the end of the workpiece supporting shelf 3.

[0030] The two ends of the workpiece support shelf 3 are respectively connected to the two corresponding shelf mounting mechanisms 2 on the left and right.

[0031] The workpiece support shelf 3 includes a shelf beam 31, disassembly sleeves 32, workpiece support components, and support plates 36. Two support plates 36 are fixedly connected to the left and right ends of the shelf beam 31, respectively. The two support plates 36 are placed into the corresponding left and right shelf support rods 21. Multiple disassembly sleeves 32 are fixedly connected laterally at equal intervals on the front and rear sides of the shelf beam 31. The number of disassembly sleeves 32 is selected as needed. A workpiece support component is installed at the end of each disassembly sleeve 32. The support plates 36 at the ends of the shelf beam 31 are placed inside the shelf support rods 21. A clockwise rotation of the screw rod 24 tightens the stud 23, causing the stud 23 to move backward relative to the mounting nut 22. The stud 23 presses the support plate 36 against the front of the gasket protrusion 25, thus fixing the shelf beam 31. The disassembly sleeves 32 are used to install the workpiece support components, which are used to directly suspend the workpiece.

[0032] The workpiece support assembly includes a bent column 33, a U-shaped column 34, and a longitudinal column 35. One end of the bent column 33 is fixedly sleeved onto the inner side of each detachable longitudinal sleeve 32. The other end of the bent column 33 is integrally connected to one end of the U-shaped column 34, and the other end of the U-shaped column 34 is integrally connected to the longitudinal column 35. The bent column 33, U-shaped column 34, and longitudinal column 35 constitute a workpiece hook, on which the workpiece can be suspended.

[0033] The hanging bracket lifting mechanism 4 is installed on the top of the column 12, and the hanging bracket lifting mechanism 5 is installed on the top of the hanging bracket lifting mechanism 4.

[0034] The hanging bracket lifting mechanism 4 includes a pull rod 41, a control plate 42, a lead screw nut 43, a fixed frame 44, a vertical groove 45, a lifting lead screw 46, and a knob 47. The top of each column 12 is fixedly connected to the bottom end of the pull rod 41. The rear side of the top of the pull rod 41 is fixedly connected to the front side of the control plate 42. The middle part of the control plate 42 is fixedly connected to the lead screw nut 43. The vertical lifting lead screw 46 is rotatably connected to the fixed frame 44 through a bearing. The lifting lead screw 46 is connected to the lead screw nut 43. The top of the lifting lead screw 46 is fixedly connected to the middle part of the knob 47. The inner side of the fixed frame 44 is provided with a vertical groove 45. The vertical groove 45 is vertically slidably connected to the protrusion on the rear side of the control plate 42. Rotating the lifting screw 46 clockwise with the knob 47 causes the control plate 42 to move downward along the vertical groove 45 due to the thread action between the lifting screw 46 and the screw nut 43. This allows the column 12 to move downward relative to the fixed frame 44 and the hanging mechanism 5 via the pull rod 41, enabling the electroplating rack body 1 to move downward within the electroplating tank. Rotating the lifting screw 46 counterclockwise with the knob 47 causes the control plate 42 to move upward along the vertical groove 45 due to the thread action between the lifting screw 46 and the screw nut 43. This allows the column 12 to move upward relative to the fixed frame 44 and the hanging mechanism 5 via the pull rod 41, enabling the electroplating rack body 1 to move upward within the electroplating tank, thus changing the relative height of the electroplating rack body 1 in the electroplating solution within the electroplating tank.

[0035] In use, the top beam 11, the column 12, and the bottom beam 13 form a rectangular electroplating rack body 1. The hanging mechanism 5 is hung on the plating rack, thus installing the electroplating rack body 1. The shelf mounting mechanism 2 is used to detachably install the workpiece support shelf 3. The number of workpiece support shelves 3 can be selected according to different workpieces. The workpiece support shelf 3 is used to suspend workpieces. The rack lifting mechanism 4 can control the distance between the electroplating rack body 1 and the hanging mechanism 5, thereby changing the height of the electroplating rack body 1 in the electroplating tank. The lifting of the electroplating rack body 1 can be controlled as needed to ensure that the workpieces on the workpiece support shelf 3 are completely immersed in the electroplating solution.

[0036] Example 2, please refer to Figures 1 to 3 The present invention provides a technical solution: an electroplating rack that can flexibly arrange workpieces. This embodiment is a further explanation of the structure of Embodiment 1.

[0037] The mounting mechanism 5 includes a mounting base 51 and an inverted U-shaped rigid hook 52. The mounting base 51 is fixedly connected to the rear side of each mounting bracket 44, and the front bottom of the inverted U-shaped rigid hook 52 is fixedly connected to the top front side of the mounting base 51. The mounting base 51 is used to install the inverted U-shaped rigid hook 52, which can be directly hung on the plating bracket.

[0038] The hooking mechanism 5 also includes an inverted U-shaped elastic hook 53 and an arc-shaped guide part 54. The bottom front side of the inverted U-shaped elastic hook 53 is fixedly connected to the top rear side of the fixed base 51. The inverted U-shaped elastic hook 53 is located inside the inverted U-shaped rigid hook 52. The bottom rear side of the inverted U-shaped elastic hook 53 is bent backward to form the arc-shaped guide part 54.

[0039] Both the inverted U-shaped rigid hook 52 and the inverted U-shaped elastic hook 53 can be made of copper, which has good conductivity.

[0040] Since the inverted U-shaped rigid hook 52 is rigid, it is easy for it to sway relative to the plating rack when hung on it. Therefore, an inverted U-shaped elastic hook 53 is added. The inverted U-shaped elastic hook 53 can deform. The inverted U-shaped elastic hook 53 is hung on the plating rack with the help of the arc guide part 54. The arc guide part 54 guides the inverted U-shaped elastic hook 53 to gradually open. The elastic deformation of the inverted U-shaped elastic hook 53 makes the inner side of the inverted U-shaped elastic hook 53 tightly attached to the plating rack, which can meet the dual requirements of stable suspension and sufficient contact conductivity.

[0041] Example 3, please refer to Figures 1 to 3 This utility model provides a technical solution: an electroplating rack that can flexibly arrange workpieces. This embodiment is structurally similar to Embodiment 2, with the difference being:

[0042] It is also equipped with a placement support mechanism 6, and two placement support mechanisms 6 can be detachably installed at both ends of the bottom beam 13.

[0043] The placement support mechanism 6 includes a U-shaped seat 61, a fixing bolt 62, a support frame 63, and a support foot 64. Two longitudinal support frames 63 are respectively provided at the bottom of both ends of the bottom beam 13. The top center of each support frame 63 is fixedly connected to the U-shaped seat 61. The groove on the U-shaped seat 61 is connected to the end of the bottom beam 13. The fixing bolt 62 is threaded on the U-shaped seat 61 and passes through the disassembly hole on the bottom beam 13. The bottom of the front and rear ends of each support frame 63 is threadedly connected to the support foot 64. The support frame 63 is detachably connected to the bottom beam 13 by means of the U-shaped seat 61 and the fixing bolt 62. The support frame 63 is stably in contact with the ground by means of the support foot 64. The two placement support mechanisms 6 constitute a stable support device, allowing the electroplating rack body 1 to be placed on a horizontal ground.

[0044] When it is not necessary to hang it on the plating rack, two placement support mechanisms 6 are installed on the bottom beam 13, and the electroplating rack body 1 can be stably placed on the ground with the help of the two placement support mechanisms 6.
