Description

TECHNICAL FIELD

[0001] The application relates to the technical field of metal plating, in particular to an automobile torsion spring terminal hanging plating production line and a production process thereof. BACKGROUND

[0002] In the field of automobile part manufacturing, electroplating process plays an important role. Electroplating can improve the corrosion resistance, wear resistance and other properties of parts, which is crucial to ensure the quality and service life of automobile parts. Especially for precision parts such as automobile torsion spring terminals, the quality of electroplating is directly related to their electrical and mechanical properties. With the continuous development of the automobile industry, the demand for automobile torsion spring terminals is increasing, and the requirements for their electroplating quality are also increasing. Therefore, developing efficient and precise electroplating production lines has become the focus of automobile part manufacturing enterprises.

[0003] In the traditional automobile torsion spring terminal hanging plating production process, a relatively simple method is usually used for operation. On the one hand, the transportation of workpieces often relies on manual or simple mechanical conveying devices, which not only has low efficiency, but also is difficult to ensure the stability and accuracy of workpiece transportation. On the other hand, when the workpiece is immersed in the plating solution tank, the worker manually adjusts the position of the hanger to immerse the target plating area in the plating solution. It is difficult to accurately immerse the target plating area in the plating solution. In addition, in order to ensure the electroplating effect, the entire workpiece is often plated, resulting in unnecessary plating material waste, which needs to be improved. SUMMARY

[0004] In order to improve the plating efficiency and avoid unnecessary plating material waste, the application provides an automobile torsion spring terminal hanging plating production line and a production process thereof.

[0005] The automobile torsion spring terminal hanging plating production line and the production process thereof provided by the application adopt the following technical solutions: An automobile torsion spring terminal hanging plating production line comprises: A plating solution tank is arranged in a ring shape, and the plating solution tank has a placement space between two ends thereof; A hanger is arranged in a frame shape, and a hook for hanging an automobile torsion spring terminal is arranged at the top of the hanger; An upper feeding conveying mechanism is located in the placement space between the two ends of the plating solution tank, and the end of the conveying direction of the upper feeding conveying mechanism is close to one end of the plating solution tank for conveying the hanger to the direction close to the plating solution tank; The unloading conveying mechanism is located in the placing space between the two ends of the plating solution tank, is adjacent to the feeding conveying mechanism, and has a first end close to the other end of the plating solution tank for conveying the hanger away from the plating solution tank. The transfer conveying mechanism is arranged above the plating solution tank and along the length direction of the plating solution tank, is used for transferring the hanger at the end of the feeding conveying mechanism into the plating solution tank, moving the hanger transferred into the plating solution tank along the length direction of the plating solution tank, and transferring the hanger in the plating solution tank to the first end of the unloading conveying mechanism.

[0006] By adopting the above technical scheme, in the production process of the automobile torsion spring terminal, the automobile torsion spring terminal is hung on the top of the hanger through the hook, then the feeding conveying mechanism feeds and conveys the hanger, so that the hanger is close to the feeding end of the plating solution tank, then the transfer conveying mechanism transfers the hanger at the end of the feeding conveying mechanism into the plating solution tank, then the transfer conveying mechanism moves the hanger transferred into the plating solution tank along the length direction of the plating solution tank for plating operation, when the hanger moves to the discharging end of the plating solution tank, the hanger is close to the first end of the unloading conveying mechanism, at this time, the plating operation of the automobile torsion spring terminal on the hanger is completed, the transfer conveying mechanism transfers the hanger at the end of the plating solution tank into the unloading conveying mechanism, and the unloading conveying mechanism feeds and conveys the hanger, so that the conveying process has high automation degree, which is beneficial to improve the plating efficiency and avoid unnecessary plating waste.

[0007] Preferably, the feeding conveying mechanism comprises a feeding frame and a feeding conveying belt, the feeding conveying belt is horizontally and transmissionally connected to the feeding frame, and the end of the feeding conveying belt close to the feeding end of the plating solution tank.

[0008] By adopting the above technical scheme, the feeding frame supports the feeding conveying belt, and the feeding conveying belt feeds and conveys the hanger, so as to convey the hanger with the automobile torsion spring terminal to the position close to the plating solution tank, thereby facilitating the transfer of the hanger into the plating solution tank by the transfer conveying mechanism.

[0009] Preferably, the feeding conveying belt is provided with feeding positioning blocks at intervals along the conveying direction thereof, and the bottom of the hanger is provided with a positioning groove for inserting the feeding positioning blocks.

[0010] By adopting the above technical scheme, when the hanger is placed on the feeding conveying belt, the feeding positioning blocks are inserted into the positioning groove, so that the hanger is conveyed in the vertical state on the feeding conveying belt, thereby facilitating the subsequent transfer operation of the hanger by the transfer conveying mechanism and improving the stability of the hanger during the conveying on the feeding conveying belt.

[0011] Preferably, the transfer and conveying mechanism includes a support frame, a moving component, a lifting component, and a clamping component. The top of the support frame is arranged in a ring shape and located directly above the plating tank. The clamping component is disposed on the lifting component for clamping the hanger. The lifting component is disposed on the moving component for driving the clamping component to move vertically up and down. The moving component is connected to the top of the support frame and moves along the length direction of the plating tank. The moving path of the moving component passes through the end of the loading conveying mechanism and the beginning of the unloading conveying mechanism.

[0012] By adopting the above technical solution, the support frame supports the moving component, the lifting component, and the clamping component. When the moving component moves the lifting component and the clamping component to the end of the feeding conveying mechanism, the lifting component drives the clamping component to move vertically up and down, cooperating with the clamping component to clamp the hanger at the end of the feeding conveying mechanism, thereby transferring the hanger into the plating tank. As the moving component moves along the length of the plating tank, the automotive torsion spring terminal in the hanger is plated in the plating tank. When the hanger moves to the end of the plating tank discharge, the lifting component drives the clamping component to move vertically up and down, cooperating with the clamping component to release the hanger after the plating operation is completed, thereby transferring the hanger to the unloading conveying mechanism.

[0013] Preferably, the clamping member is configured as a clamping cylinder, and the top of the hanger protrudes upward to form a protrusion for the clamping cylinder to clamp.

[0014] By adopting the above technical solution, the clamping cylinder clamps the protrusion on the top of the hanger to clamp and fix the hanger, which is convenient and quick.

[0015] Preferably, the clamping plate of the clamping cylinder is provided with a limiting block on its inner side, and the protrusion is provided with a limiting groove for the limiting block to be inserted.

[0016] By adopting the above technical solution, when the clamping plate of the clamping cylinder clamps the protrusion, the limiting block is inserted into the limiting groove, making it difficult for the hanger to be released from the clamping cylinder, thereby improving the stability of clamping.

[0017] Preferably, the moving component includes a moving block and a moving drive, the moving drive being disposed on the support frame for driving the moving block to move around the top of the support frame.

[0018] By adopting the above technical solution, the moving drive unit drives the moving block to move around the top of the support frame, so as to realize that the moving block drives the lifting unit and the clamping unit to move the hanger along the length direction of the plating tank so that the hanger can be plating in the plating tank.

[0019] Preferably, the lifting component is configured as a lifting cylinder, which is vertically fixedly disposed at the bottom of the moving block, and the clamping cylinder is fixedly connected to the piston rod end of the lifting cylinder.

[0020] By adopting the above technical solution, the extension and retraction of the piston rod of the lifting cylinder drives the clamping cylinder to move vertically up and down, thereby enabling the clamping cylinder to clamp the hanger to move vertically up and down. This facilitates the transfer process of the hanger in the feeding conveyor mechanism, the plating tank, and the unloading conveyor mechanism, and controls the depth of the automotive torsion spring terminal on the hanger immersed in the plating tank. This allows the automotive torsion spring terminal to accurately immerse the target plating area in the plating solution, which helps to avoid unnecessary waste of plating material.

[0021] Preferably, the system further includes a control system for controlling the coordinated operation of the feeding conveyor, the unloading conveyor, and the transfer conveyor. The control system includes a control panel, a first sensor, a second sensor, and a third sensor. The control panel is mounted on the support frame. The first sensor is located at the end of the feeding conveyor to sense the position of the fixture to be plated. The second sensor is located at the beginning of the unloading conveyor to sense the position of the already plated fixture. The third sensor is located on the clamping member to sense the position of the fixture in the plating bath. The first sensor, the second sensor, and the third sensor are all electrically connected to the control panel.

[0022] By adopting the above technical solution, the control system controls the actions of the feeding conveyor, the unloading conveyor, and the transfer conveyor. When the hanger is conveyed to the end of the feeding conveyor, the first sensor senses the hanger and sends an electrical signal to the control panel, causing the feeding conveyor to stop its conveying action. The transfer conveyor then transfers the hanger at the end of the feeding conveyor to the plating bath. The third sensor senses the position of the hanger in the plating bath and sends an electrical signal to the control panel. The transfer conveyor adjusts the position of the automotive torsion spring terminal to immerse the target plating area in the plating bath to avoid unnecessary waste of plating material. When the hanger moves to the discharge end of the plating bath, the transfer conveyor transfers the plating hanger in the plating bath to the beginning of the unloading conveyor. The second sensor senses the hanger and sends an electrical signal to the control panel, and the unloading conveyor begins to convey the hanger to realize the unloading and conveying of the plating hanger. The whole process is highly automated, and the various mechanisms cooperate and respond quickly, which is conducive to improving plating efficiency.

[0023] A plating process for automotive torsion spring terminals, using the aforementioned automotive torsion spring terminal plating production line, includes the following steps: S1: Loading: The automotive torsion spring terminal is hung on the hanger via a hook. The hanger is placed in the loading conveyor mechanism, which transports the hanger to the end near the inlet of the plating tank. S2: First transfer, the transfer conveying mechanism transfers the hanger located at the feeding end of the plating tank to the plating tank; S3: Moving plating, the transfer conveyor mechanism drives the hanger transferred to the plating tank to move and plating along the length of the plating tank; S4: Second transfer: When the hanger moves to one end of the plating tank discharge, the transfer conveying mechanism transfers the hanger located at the discharge end of the plating tank to the beginning of the unloading conveying mechanism. S5: Unloading. The unloading conveyor will transport the fixture to the end away from the plating bath outlet for unloading.

[0024] By adopting the above technical solution, in the production process of plating automotive torsion spring terminals, the automotive torsion spring terminals are hung on the top of the hanger via hooks. Then, the feeding conveyor conveys the hanger to bring it close to the inlet end of the plating tank, realizing the feeding operation of the hanger. Then, the transfer conveyor transfers the hanger located at the end of the feeding conveyor to the plating tank, realizing the first transfer process. Subsequently, the transfer conveyor moves the hanger transferred to the plating tank along the length of the plating tank for plating, realizing the moving plating process. When the hanger moves to the outlet end of the plating tank, it is close to the beginning of the unloading conveyor. At this time, the plating operation of the automotive torsion spring terminals on the hanger is completed. The transfer conveyor transfers the hanger at the end of the plating tank to the unloading conveyor, realizing the second transfer operation. Subsequently, the unloading conveyor unloads the hanger, realizing the unloading operation of the hanger. The conveying process has a high degree of automation, which is conducive to improving plating efficiency and avoiding unnecessary plating material waste.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a plating tank, a hanger, a feeding conveyor, an unloading conveyor, and a transfer conveyor, the automotive torsion spring terminal is hung on the top of the hanger via a hook. Then, the feeding conveyor feeds the hanger, bringing it close to the inlet end of the plating tank. The transfer conveyor then transfers the hanger, located at the end of the feeding conveyor, into the plating tank. Subsequently, the transfer conveyor moves the hanger, now in the plating tank, along the length of the tank for plating. When the hanger reaches the outlet end of the plating tank, it is close to the beginning of the unloading conveyor, at which point the plating operation on the automotive torsion spring terminal on the hanger is complete. The transfer conveyor then transfers the hanger from the end of the plating tank into the unloading conveyor, which unloads the hanger. The conveying process is highly automated, which helps improve plating efficiency and avoids unnecessary waste of plating material.

[0026] 2. By setting up a feeding positioning block and a positioning groove, when the hanger is placed on the material conveyor belt, the feeding positioning block is inserted into the positioning groove, so that the hanger is transported vertically on the feeding conveyor belt, which facilitates the subsequent transfer operation of the hanger by the transfer conveyor mechanism and helps to improve the stability of the hanger when it is transported on the feeding conveyor belt.

[0027] 3. By setting up a support frame, a moving component, a lifting component, and a clamping component, the support frame supports the moving component, the lifting component, and the clamping component. When the moving component drives the lifting component and the clamping component to move to the end of the feeding conveyor mechanism, the lifting component drives the clamping component to move vertically up and down, cooperating with the clamping component to clamp the hanger at the end of the feeding conveyor mechanism, thereby transferring the hanger into the plating tank. As the moving component moves along the length of the plating tank, the automotive torsion spring terminal in the hanger is plated in the plating tank. When the hanger moves to the end of the plating tank discharge, the lifting component drives the clamping component to move vertically up and down, cooperating with the clamping component to release the hanger after the plating operation is completed, thereby transferring the hanger to the unloading conveyor mechanism.

[0035] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0036] This application discloses a plating production line for automotive torsion spring terminals, referring to... Figure 1 The system includes a plating tank 1, a hanger 2, a feeding conveyor 4, an unloading conveyor 5, and a transfer conveyor 6. The plating tank 1 is arranged in a ring shape with a placement space between its two ends. The feeding conveyor 4 and the unloading conveyor 5 are arranged side by side in the placement space. The transfer conveyor 6 is located above the plating tank 1. This layout allows the various mechanisms to cooperate with each other, realizing a highly efficient continuous operation for plating automotive torsion spring terminals, improving production efficiency, and facilitating the accurate transfer and positioning of the hanger 2, thereby improving the precision of the plating operation.

[0037] Reference Figure 1 and Figure 2 The plating bath 1 is arranged in a ring shape, with a placement space between its two ends. This ring design increases the length of the plating bath 1, allowing the hanger 2 to have a longer plating time within it. Simultaneously, the placement space in the middle can be efficiently utilized for arranging the loading conveyor 4 and the unloading conveyor 5. In this embodiment, the plating bath 1 is made of corrosion-resistant plastic material, such as polyvinyl chloride (PVC). Alternatively, stainless steel can be used, as it possesses good strength and corrosion resistance.

[0038] Reference Figure 3 The hanger 2 is frame-shaped, with a hook 3 at the top for holding the automotive torsion spring terminal. The frame-shaped hanger 2 has a stable structure, ensuring the stability of the automotive torsion spring terminal during the plating process. The hook 3 can be made of metal, such as iron or copper, and its shape can be hook-shaped to easily hold the automotive torsion spring terminal. The hook 3 can also be designed to be adjustable to accommodate automotive torsion spring terminals of different sizes.

[0039] Reference Figure 1 The feeding conveyor 4 is located in the placement space between the two ends of the plating tank 1. Its end in the conveying direction, near the material inlet end of the plating tank 1, is used to convey the hanger 2 towards the plating tank 1. Specifically, the feeding conveyor 4 includes a feeding frame 41 and a feeding conveyor belt 42. The feeding conveyor belt 42 is horizontally connected to the feeding frame 41, and its end in the conveying direction is near the material inlet end of the plating tank 1. In this embodiment, the feeding frame 41 is welded from a steel structure to ensure sufficient strength. The feeding conveyor belt 42 can be a belt conveyor belt made of rubber, or a chain conveyor belt made of alloy steel. In addition, the feeding conveyor belt 42 is provided with feeding positioning blocks 7 at intervals along its conveying direction. (Referring to...)Figure 4 The bottom of the hanger 2 is provided with a positioning groove 8 for the insertion of the feeding positioning block 7. The cooperation between the feeding positioning block 7 and the positioning groove 8 can ensure the accurate position of the hanger 2 during the feeding and conveying process and prevent the hanger 2 from shifting. The feeding positioning block 7 can be square or round, as long as it can cooperate with the positioning groove 8, which will not be elaborated here.

[0040] Reference Figure 1 The unloading conveyor 5 is located in the space between the two ends of the plating bath 1. The unloading conveyor 5 and the loading conveyor 4 are arranged adjacent to each other. The first end of the unloading conveyor 5, closer to the outlet end of the plating bath 1, is used to convey the hanger 2 away from the plating bath 1. The structure of the unloading conveyor 5 is similar to that of the loading conveyor 4. The unloading conveyor 5 includes an unloading frame 51 and an unloading conveyor belt 52. The unloading conveyor belt 52 is horizontally connected to the unloading frame 51, and its conveying direction is opposite to that of the loading conveyor belt 42. The unloading frame 51 can also be made of steel, and the unloading conveyor belt 52 can be either a belt type or a chain type. (See also...) Figure 4 The feeding conveyor belt 52 is provided with feeding positioning blocks 11 for inserting into the positioning slots 8 at intervals along its conveying direction. The cooperation between the feeding positioning blocks 11 and the positioning slots 8 can ensure the accurate position and stability of the hanger 2 during the feeding conveying process, so as to avoid the hanger 2 from deviating.

[0041] Reference Figure 1 The transfer conveying mechanism 6 is positioned above the plating bath 1 and along its length. It is used to transfer the hanger 2 from the end of the loading conveying mechanism 4 into the plating bath 1, move the hanger 2 from the plating bath 1 along its length, and transfer the hanger 2 from the plating bath 1 to the beginning of the unloading conveying mechanism 5. (Refer to...) Figure 5 The transfer and conveying mechanism 6 includes a support frame 61, a moving component 62, a lifting component, and a clamping component. The top of the support frame 61 is arranged in a ring shape and is located directly above the plating tank 1. The support frame 61 provides support and a moving track for the moving component 62. In this embodiment, the support frame 61 is welded from metal tubing.

[0042] Reference Figure 5 and Figure 6The moving component 62 includes a moving block 621 and a moving drive component 622. The moving drive component 622 is mounted on the support frame 61 and drives the moving block 621 to move around the top of the support frame 61. The moving drive component 622 can be a motor, which drives the moving block 621 to move through a gear and rack transmission or a chain transmission. In this embodiment, the lifting component is set as a lifting cylinder 63, which is fixedly mounted on the bottom of the moving block 621, and the piston rod of the lifting cylinder 63 is set vertically downward. The clamping component is fixedly connected to the end of the piston rod of the lifting cylinder 63. The lifting cylinder 63 can precisely control the up and down movement of the clamping component. At the same time, the clamping component is set as a clamping cylinder 64, and the top of the hanger 2 protrudes upward to form a protrusion 9 for the clamping cylinder 64 to clamp. Furthermore, the clamping plate of the clamping cylinder 64 is provided with a limit block 12, and the protrusion 9 is provided with a limit groove 13 for the limit block 12 to be inserted. The cooperation between the limit block 12 and the limit groove 13 can ensure the stability of clamping.

[0043] Reference Figure 1 The automotive torsion spring terminal plating production line also includes a control system 10 for controlling the coordinated actions of the feeding conveyor 4, the unloading conveyor 5, and the transfer conveyor 6. Specifically, the control system 10 includes a control panel 101, a first sensor 102, a second sensor 103, and a third sensor 104. The control panel 101 is mounted on a support frame 61. The first sensor 102 is located at the end of the feeding conveyor 4 to sense the position of the hanger 2 to be plated. The second sensor 103 is located at the beginning of the unloading conveyor 5 to sense the position of the already plated hanger 2. The third sensor 104 is located on a clamping component to sense the position of the hanger 2 within the plating bath 1. The first sensor 102, the second sensor 103, and the third sensor 104 are all electrically connected to the control panel 101. Through the cooperation of these sensors and the control panel 101, automated linkage of the various mechanisms can be achieved, improving production accuracy and efficiency.

[0044] This application also discloses a plating process for automotive torsion spring terminals, using the aforementioned automotive torsion spring terminal plating production line, including the following steps: S1: Loading. The automotive torsion spring terminals are hung on the hanger 2 via hooks 3. The hanger 2 is placed in the loading conveyor mechanism 4, which transports the hanger 2 to the end near the inlet of the plating tank 1. In this step, the operator first hangs the automotive torsion spring terminals one by one on the hooks 3 of the hanger 2, and then places the hanger 2 stably on the loading conveyor belt 42. The loading conveyor belt 42 starts, transporting the hanger 2 along the conveying direction. The loading positioning block 7 cooperates with the positioning groove 8 at the bottom of the hanger 2 to ensure that the hanger 2 accurately reaches the end near the inlet of the plating tank 1. S2: In the first transfer, the transfer conveying mechanism 6 transfers the hanger 2 located at the inlet end of the plating tank 1 into the plating tank 1. When the hanger 2 reaches the inlet end of the plating tank 1, the first sensor 102 senses the position of the hanger 2 and transmits the signal to the control panel 101. The control panel 101 controls the moving component 62 of the transfer conveying mechanism 6 to move above the hanger 2, the lifting cylinder 63 descends, the clamping cylinder 64 clamps the protrusion 9 on the top of the hanger 2, and then the lifting cylinder 63 rises, and the moving component 62 transfers the hanger 2 into the plating tank 1. S3: Moving plating: The transfer and conveying mechanism 6 drives the hanger 2, which has been transferred into the plating bath 1, to move and perform plating operations along the length of the plating bath 1. After the transfer and conveying mechanism 6 places the hanger 2 into the plating bath 1, the moving component 62 moves along the length of the plating bath 1, causing the hanger 2 to move slowly in the plating solution for plating. The third sensor 104 senses the position of the hanger 2 in the plating bath 1 in real time to ensure that the moving speed and position of the hanger 2 meet the plating requirements. S4: Second transfer. When the hanger 2 moves to the discharge end of the plating tank 1, the transfer conveying mechanism 6 transfers the hanger 2 from the discharge end of the plating tank 1 to the beginning of the unloading conveying mechanism 5. When the hanger 2 moves to the discharge end of the plating tank 1, the third sensor 104 senses it and transmits the signal to the control panel 101. The control panel 101 controls the transfer conveying mechanism 6 to transfer the hanger 2 from the plating tank 1 to the beginning of the unloading conveying mechanism 5. S5: Unloading. The unloading conveyor 5 transports the hanger 2 to the end away from the outlet of the plating tank 1 for unloading. After the hanger 2 is transferred to the beginning of the unloading conveyor 5, the unloading conveyor belt 52 starts and transports the hanger 2 to the end away from the outlet of the plating tank 1. The operator can remove the electroplated automotive torsion spring terminal from the hanger 2 here.

[0045] 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.
