Description

Technical Field

[0001] The present invention relates to the technical field of aluminum terminal blocks, and particularly to an aluminum terminal block copper plating device and process. Background Art

[0002] Both aluminum and copper are commonly used conductive materials. Since the price of copper is higher than that of aluminum, most of the existing terminal blocks are made of aluminum, and then copper plating is carried out on the aluminum material to increase the conductive efficiency of the terminal block.

[0003] When copper plating the aluminum terminal block, workers usually hold a clamping device to fix one end of the aluminum terminal block, and then immerse the aluminum terminal block in copper water to achieve copper plating of the aluminum terminal block. To avoid the thin thickness of the copper plating on the outer side of the aluminum terminal block, which is likely to expose the aluminum terminal block, multiple copper plating processes are required for the aluminum terminal block. After the existing copper plating process is completed for the aluminum terminal block, workers need to remove the copper-plated aluminum terminal block and install the uncopper-plated aluminum terminal block. If there are unqualified conditions such as thin copper plating thickness in the copper-plated aluminum terminal blocks, these aluminum terminal blocks need to be copper-plated again. This will result in a long copper plating time, reducing the copper plating efficiency of the aluminum terminal block and being unfavorable for the copper plating work of the aluminum terminal block. Summary of the Invention

[0004] In order to overcome the drawbacks that after the existing copper plating process for the aluminum terminal block is completed, workers need to remove the copper-plated aluminum terminal block and install the uncopper-plated aluminum terminal block, and if there are unqualified conditions such as thin copper plating thickness in the copper-plated aluminum terminal blocks, these aluminum terminal blocks need to be copper-plated again, resulting in a long copper plating time, reducing the copper plating efficiency of the aluminum terminal block and being unfavorable for the copper plating work of the aluminum terminal block, the technical problem of the present invention is: to provide an aluminum terminal block copper plating device and process.

[0005] Technical solution: An aluminum wiring terminal copper plating device, including a chassis, a support rod and a mounting plate. The top of the chassis is fixedly connected with a mounting plate through the support rod. Both sides of the bottom of the mounting plate are connected with pulleys through rotating rods. A conveyor belt is wound between the outer sides of the two pulleys. A reduction motor connected to the rotating rod of the adjacent pulley is embedded in the top of the mounting plate. A plurality of fixed blocks are detachably connected to the outer side of the conveyor belt. A sliding rod is slidably connected to the fixed block. A circular piece is fixedly connected to the lower part of the sliding rod. A first spring sleeved on the outer side of the sliding rod is fixedly connected between the circular piece and the fixed block. A clamping assembly for fixing the aluminum wiring terminal is fixedly connected to the bottom end of the sliding rod. A feeding assembly for the aluminum wiring terminal is arranged on one side of the top of the chassis. A containing box for containing copper plating solution is placed on the other side of the top of the chassis. A drying box is installed on the top of the chassis. A collection box is placed on the top of the chassis. The side wall of the mounting plate is bolted with a pressing frame located above the containing box through a support rod. A guiding frame is fixedly connected to the support rod through a connecting rod. A guiding groove is opened in the upper part of the guiding frame. An inverted trapezoidal groove is opened on one side of the lower part of the guiding frame. The guiding groove is located above and communicated with the inverted trapezoidal groove, and the inverted trapezoidal groove is located on one side of the collection box.

[0006] In a preferred embodiment of the present invention, a spherical body is rotatably arranged at the top end of the sliding rod. The outer sides of the spherical body and the downward protrusion on the pressing frame are both smooth surfaces to reduce the contact resistance.

[0007] In a preferred embodiment of the present invention, the clamping assembly includes a connecting frame. The connecting frame is fixedly connected to the bottom end of the sliding rod. A guide rod is slidably connected to the connecting frame. A connecting piece is fixedly connected to the lower part of the guide rod. A second spring sleeved on the outer side of the guide rod is fixedly connected between the connecting piece and the connecting frame. Symmetrically distributed swing rods are rotatably connected inside the connecting frame. An expansion rod is rotatably connected to the swing rod. The telescopic end of the expansion rod is rotatably connected to the lower end of the guide rod. A guide block cooperating with the guide groove is fixedly connected to the upper end of the guide rod.

[0008] In a preferred embodiment of the present invention, a spherical protrusion is arranged at the end of the swing rod, and the spherical protrusion is made of rubber material.

[0009] In a preferred embodiment of the present invention, the feeding assembly includes a feeding box. The feeding box is fixedly connected to the top of the chassis. An inlet is opened on one side wall of the feeding box. Symmetrically distributed limiting strips are fixedly connected inside the feeding box. The symmetrically distributed limiting strips are located outside the aluminum wiring terminal. Placing plates are fixedly connected to both sides inside the feeding box. The placing plates are located below the limiting strips. A transfer piece for conveying the aluminum wiring terminal is arranged at the lower part of the feeding box. A transmission piece is arranged on one side of the feeding box close to the support rod.

[0010] In a preferred embodiment of the present invention, the transfer member includes symmetrically distributed transmission wheels. The symmetrically distributed transmission wheels are rotatably connected to the inside of the feeding box through a shaft rod, and the transmission wheels are located below the placing plate. A flat belt is wound around the outer sides of the symmetrically distributed transmission wheels. Blocks are fixedly connected to the outer side surface of the flat belt at equal intervals. The shaft rod of one of the transmission wheels penetrates through the feeding box and is fixedly connected with a one-way gear.

[0011] In a preferred embodiment of the present invention, the transmission member includes a sliding frame. The sliding frame is slidably located inside the feeding box. A third spring is fixedly connected between the sliding frame and the feeding box. A limiting groove is formed in another side wall of the feeding box. One side of the sliding frame passes through the limiting groove and is fixedly connected with a rack frame. An outlet is formed in one side of the upper part of the feeding box. A contact frame is fixedly connected to the end of the sliding frame. A wedge-shaped plate matched with the contact frame is fixedly connected to the bottom of the connecting frame.

[0012] In a preferred embodiment of the present invention, there is a frictional resistance on the contact side between the sliding frame and the limiting groove for the sliding frame to slowly reset.

[0013] In a preferred embodiment of the present invention, the connection position of the wedge-shaped plate is misaligned with the connection position of the guide rod.

[0014] A process of an aluminum wiring terminal copper plating device specifically includes the following steps:

[0015] S1: The aluminum wiring terminals are conveyed to the placing plate inside the feeding box through an external conveying device, and the reduction motor is started to work to drive the pulley connected thereto to rotate, so that the conveyor belt drives the fixed block and the parts thereon to move;

[0016] S2: The wedge-shaped plate moves to squeeze the contact frame to drive the sliding frame to move downward. When the sliding frame moves downward to the same height as the placing plate, the sliding frame continues to move downward so that the rack frame thereon meshes with the one-way gear to drive the connected transmission wheel to rotate. The flat belt drives the blocks thereon to move to push the aluminum wiring terminals on the placing plate to move onto the sliding frame. After the wedge-shaped plate moves away from the contact frame, under the action of the third spring, the sliding frame can move upward to move the aluminum wiring terminals into the outlet of the feeding box;

[0017] S3: Before the guiding block enters the inclined part at the front side of the inverted trapezoidal groove, at this time, the swing rod is located at the outer position behind the uppermost aluminum terminal in the feeding box. The fixed block continues to move, and the guiding block will gradually move upward and approach the middle position of the aluminum terminal. The upward movement of the guiding block makes the swing rod swing upward through the guide rod and the telescopic rod. When the guiding block moves into the guiding groove, at this time, the swing rod moves to the middle position of the aluminum terminal and completes the upward swing to fix the aluminum terminal in the feeding box.

[0018] S4: When the fixed block continues to move, it drives the clamped aluminum terminal to move out of the feeding box through the discharge port and into the storage box. The sliding rod is pushed downward by the protrusion of the extrusion frame, causing the connecting frame to move downward and drive the lower part of the aluminum terminal into the copper plating solution in the storage box, realizing the copper plating work on the aluminum terminal.

[0019] S5: When the fixed block continues to move, the copper-plated aluminum terminal enters the drying box for drying. When the guiding block moves to the inclined part at the rear side of the inverted trapezoidal groove, under the action of the elastic force of the second spring, the guide rod can move downward. After the guiding block moves away from the inclined part at the rear side of the inverted trapezoidal groove, at this time, the swing rod resets to release the fixation on the copper-plated aluminum terminal, and the copper-plated aluminum terminal falls into the receiving box for storage.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] Through the cooperation of the clamping component and the feeding component, the present invention can realize the automatic feeding of aluminum terminals. Through the cooperation of the clamping component with the inverted trapezoidal groove and the guiding groove, the automatic fixation and automatic release of fixation on aluminum terminals can be realized. Therefore, it is not necessary to stop the copper plating work every time after the copper plating of aluminum terminals is completed, which can save a lot of time and improve the copper plating efficiency of aluminum terminals. Through the cooperation of the sliding rod and the extrusion frame, multiple copper plating operations on aluminum terminals can be realized, which can avoid the thin copper plating thickness on the outer side of aluminum terminals, easily exposing the aluminum terminals and affecting subsequent use.

Detailed implementation manners

[0029] Although the present invention may be described with respect to a particular application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as: above, below, upward, downward, etc. are used to describe the drawings and do not represent a limitation on the scope of the present invention as defined by the appended claims. Any numerical labels such as: first or second are merely illustrative and are not intended to limit the scope of the present invention in any way.

[0030] An aluminum terminal copper plating device, as Figures 1-6As shown in the figure, it includes a chassis 1, a support rod 2 and a mounting plate 3. The top of the chassis 1 is fixedly connected with a mounting plate 3 through the support rod 2. Both the front and rear sides of the bottom of the mounting plate 3 are connected with pulleys 4 through rotating rods. A conveyor belt 5 is wound between the outer sides of the front and rear pulleys 4. A reduction motor 6 connected to the rotating rod on the rear pulley 4 is embedded in the top of the mounting plate 3. A plurality of fixed blocks 7 are detachably connected to the outer side of the conveyor belt 5 (the number of fixed blocks 7 can be changed according to requirements). A sliding rod 8 is slidably connected to the fixed block 7. A spherical body is rotatably arranged at the top end of the sliding rod 8. An annular piece 9 is fixedly connected to the lower part of the sliding rod 8. A first spring 10 sleeved on the outer side of the sliding rod 8 is fixedly connected between the annular piece 9 and the fixed block 7. A clamping assembly for fixing the aluminum terminal is fixedly connected to the bottom end of the sliding rod 8. Starting the reduction motor 6 to work drives the pulley 4 connected to it to rotate, and drives the fixed block 7, the sliding rod 8 and the clamping assembly to move through the conveyor belt 5. A feeding assembly for aluminum terminals is arranged on the right front side of the top of the chassis 1. A storage box 18 for containing copper plating solution is placed on the left side of the top of the chassis 1. A drying box 19 is installed on the rear side of the top of the chassis 1. A collection box 20 is placed on the right rear side of the top of the chassis 1. The left side wall of the mounting plate 3 is bolted with a pressing frame 35 located above the storage box 18 through a support rod. The spherical body of the sliding rod 8 and the outer side of the downward protrusion on the pressing frame 35 are both smooth surfaces to reduce the contact resistance. Through the cooperation of the sliding rod 8 and the pressing frame 35, multiple copper plating operations on the aluminum terminal can be realized. Therefore, it can avoid the thin thickness of the copper plating on the outer side of the aluminum terminal, which is likely to expose the aluminum terminal and affect subsequent use. A guide frame 36 is fixedly connected to the support rod 2 through a connecting rod. A guide groove 37 is formed in the guide frame 36. An inverted trapezoidal groove 38 is formed on the right side of the guide frame 36. The guide groove 37 is located above the inverted trapezoidal groove 38 and the two are communicated. Through the cooperation of the clamping assembly and the feeding assembly, the automatic feeding of the aluminum terminal can be realized. Through the cooperation of the clamping assembly with the inverted trapezoidal groove 38 and the guide groove 37, the automatic fixing and automatic release of the aluminum terminal can be realized. Therefore, it is not necessary to stop the copper plating work every time the aluminum terminal finishes the copper plating work. Therefore, a large amount of time can be saved and the copper plating efficiency of the aluminum terminal can be improved.

[0031] The clamping assembly includes a connecting frame 11, the connecting frame 11 is fixedly connected to the bottom end of the sliding rod 8, a guide rod 12 is slidably connected to the connecting frame 11, a connecting piece 13 is fixedly connected to the lower part of the guide rod 12, and a second spring 14 sleeved on the outer side of the guide rod 12 is fixedly connected between the connecting piece 13 and the connecting frame 11. Symmetrically distributed swing rods 15 are rotatably connected inside the connecting frame 11, a telescopic rod 16 is rotatably connected to the swing rod 15, and the telescopic end of the telescopic rod 16 is rotatably connected to the lower end of the guide rod 12. A spherical protrusion is provided at the end of the swing rod 15, and the spherical protrusion on the swing rod 15 is made of rubber. A guide block 17 cooperating with the guide groove 37 is fixedly connected to the upper end of the guide rod 12. When the guide block 17 enters the inclined part at the front side of the inverted trapezoidal groove 38, at this time, the swing rod 15 is located at the outer position behind the uppermost aluminum terminal in the feeding box 21. As the fixed block 7 continues to move, the guide block 17 will gradually move upward and approach the middle position of the aluminum terminal. The upward movement of the guide block 17 drives the guide rod 12 to move upward. The upward movement of the guide rod 12 compresses the second spring 14 through the connecting piece 13 thereon. The upward movement of the guide rod 12 can make the swing rod 15 swing upward through the telescopic rod 16. When the guide block 17 moves into the guide groove 37, at this time, the upward swing of the swing rod 15 is completed, and the swing rod 15 moves to the middle position of the aluminum terminal, completing the fixation of the aluminum terminal in the feeding box 21.

[0032] The feeding component includes a feeding box 21, which is fixedly connected to the top of the chassis 1. An inlet 22 is formed on the right side wall of the feeding box 21. Two symmetrically arranged front and rear limiting strips 221 are fixedly connected to the left inner side of the feeding box 21. The front and rear two limiting strips 221 are located outside the aluminum terminal. On both the front and rear sides inside the feeding box 21, there are fixedly connected holding plates 27. The holding plates 27 are located below the limiting strips 221. A transfer member for transferring the aluminum terminal is arranged at the lower part of the feeding box 21, and a transmission member is arranged on the left side of the feeding box 21. The transfer member includes two transmission wheels 23, which are respectively rotatably connected to the left and right sides inside the feeding box 21 through shaft rods, and the transmission wheels 23 are located below the holding plates 27. A flat belt 24 is wound around the outer sides of the two transmission wheels 23. Blocks 25 are fixedly connected to the outer side surface of the flat belt 24 at equal intervals. The blocks 25 are located in the gap between the front and rear two holding plates 27. The front end of the shaft rod of the left transmission wheel 23 penetrates to the outside of the feeding box 21 and is fixedly connected with a one-way gear 26. The transmission member includes a sliding frame 29, which slides inside the feeding box 21. A third spring 30 is fixedly connected between the sliding frame 29 and the feeding box 21. A limiting groove 28 is formed on the left side wall of the feeding box 21. There is frictional resistance on the contact side between the sliding frame 29 and the limiting groove 28 for the sliding frame 29 to slowly reset. The left end of the sliding frame 29 passes through the limiting groove 28 and is fixedly connected with a rack frame 31 located outside the feeding box 21. The rack frame 31 and the one-way gear 26 are on the same plane. An outlet 32 is formed on the upper left side of the feeding box 21. A contact frame 33 is fixedly connected to the left end of the sliding frame 29. A wedge-shaped plate 34 matched with the contact frame 33 is fixedly connected to the bottom of the connecting frame 11. The connection position of the wedge-shaped plate 34 is misaligned with the connection position of the guide rod 12. When the wedge-shaped plate 34 moves to squeeze the contact frame 33, it drives the sliding frame 29 to move downward. When the sliding frame 29 moves downward to the same height as the holding plate 27, at this time, the rack frame 31 meshes with the one-way gear 26. The sliding frame 29 continues to drive the rack frame 31 to move downward, and through the one-way gear 26, the transmission wheel 23 connected thereto rotates. Therefore, the flat belt 24 can drive the blocks 25 thereon to move and push the aluminum terminal on the holding plate 27 to move, so that the aluminum terminal close to the sliding frame 29 moves onto it. After the wedge-shaped plate 34 moves away from the contact frame 33, at this time, under the action of the third spring 30, the sliding frame 29 can move upward.

[0033] During use, the operator first conveys the aluminum terminal to the placing plate 27 in the feeding box 21 through the conveying device of the peripheral device, and the upper joint of the aluminum terminal is located above the two limiting strips 221. Subsequently, the operator starts the reduction motor 6 to work. The reduction motor 6 drives the pulley 4 connected to it to rotate, and through the conveyor belt 5, the other pulley 4 rotates synchronously. During this process, the fixed block 7 can be driven to move through the conveyor belt 5. The movement of the fixed block 7 drives the parts on it to move. When the wedge plate 34 moves and contacts the contact frame 33, the continuous movement of the fixed block 7 can cause the wedge plate 34 to squeeze the contact frame 33 to drive the sliding frame 29 to move downward, and the third spring 30 is compressed accordingly. The downward movement of the sliding frame 29 drives the rack frame 31 to move downward. When the sliding frame 29 moves downward to the same height as the placing plate 27, at this time, the rack frame 31 meshes with the one-way gear 26. The sliding frame 29 continues to drive the rack frame 31 to move downward, and through the transmission of the one-way gear 26, the driving wheel 23 connected to it rotates. Therefore, the flat belt 24 can drive the block 25 on it to move and push the aluminum terminal on the placing plate 27 to move, so that the aluminum terminal moves to the upper side of the sliding frame 29 at this time. After the wedge plate 34 moves away from the contact frame 33, at this time, under the action of the third spring 30, the sliding frame 29 can move upward. During the upward movement of the sliding frame 29, the aluminum terminal can gradually move away from the limiting strip 221. (During this process, due to the frictional resistance on the contact side between the sliding frame 29 and the limiting groove 28, the sliding frame 29 is prevented from quickly moving upward and resetting under the elastic force of the third spring 30, resulting in collision, displacement or deflection with the aluminum terminal, affecting the subsequent fixing work of the aluminum terminal). The aluminum terminal on the sliding frame 29 then moves into the discharge port 32 of the feeding box 21, facilitating the subsequent copper plating process for the aluminum terminal (when the rack frame 31 moves upward and cooperates with the one-way gear 26, the driving wheel 23 connected to it cannot rotate. The characteristics of the above one-way gear 26 are prior art, so no more description will be given here). When the guiding block 17 enters the inclined part in front of the inverted trapezoidal groove 38, at this time, the swing rod 15 is located outside the rear of the uppermost aluminum terminal in the feeding box 21. The fixed block 7 continues to move, and the guiding block 17 will gradually move upward and approach the middle position of the aluminum terminal. The upward movement of the guiding block 17 drives the guide rod 12 to move upward. The upward movement of the guide rod 12 compresses the second spring 14 through the connecting piece 13 on it. The upward movement of the guide rod 12 can cause the swing rod 15 to swing upward through the telescopic rod 16. When the guiding block 17 moves into the guiding groove 37, at this time, the upward swing of the swing rod 15 is completed, and the swing rod 15 moves to the middle position of the aluminum terminal, completing the fixation of the aluminum terminal in the feeding box 21. The continuous movement of the fixed block 7 can drive the clamped aluminum terminal to move out through the discharge port 32 of the feeding box 21. The continuous movement of the fixed block 7 can drive the clamped aluminum terminal to move and enter the storage box 18. When the sliding rod 8 moves and contacts the protrusion of the extrusion frame 35,The sliding rod 8 is squeezed downward by the protrusion of the squeezing frame 35, causing the connecting frame 11 to move downward, driving the lower part of the aluminum terminal into the copper plating solution in the storage box 18, thereby realizing the copper plating operation on the aluminum terminal (since there are three protrusions on the squeezing frame 35, the aluminum terminal can be copper plated three times. When multiple copper plating operations are required, the squeezing frame 35 can be changed according to actual needs, and this copper plating is an electroplating method). The continuous copper plating operation effectively avoids the unqualified rate of copper plating, is conducive to saving copper plating time, and improving the copper plating work efficiency. When the sliding rod 8 no longer contacts the squeezing frame 35, under the action of the elastic force of the first spring 10, the connecting frame 11 can move upward. At this time, the aluminum terminal will move away from the copper plating solution in the storage box 18, thus completing the copper plating of the aluminum terminal. When the fixed block 7 continues to move, the copper-plated aluminum terminal can enter the drying box 19 for drying. When the fixed block 7 continues to move and drives the guide block 17 to move to the inclined part behind the trapezoidal groove 38, under the action of the elastic force of the second spring 14, the guide rod 12 can move downward. After the guide block 17 moves away from the inclined part behind the trapezoidal groove 38, the swing rod 15 is reset to release the fixation on the copper-plated aluminum terminal, and the copper-plated aluminum terminal falls into the collection box 20 for storage. Through the above operations, the automatic copper plating operation on the aluminum terminal can be realized without the intervention of workers. At the same time, there is no need to stop the copper plating work after each copper plating of the aluminum terminal, so a large amount of time can be saved and the copper plating efficiency of the aluminum terminal can be improved.

Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited by the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
