Description

Technical Field

[0001] The present invention relates to an anodic oxidation test production line and test method for aluminum surface treatment. Background Art

[0002] Currently, a Chinese patent with the publication number CN112746300A discloses an anodic oxidation production line and production process, which relates to the technical field of workpiece electroplating. It includes a loading cart arranged on the feeding side of the production tank. The loading cart is provided with a loading rack, and a hanging rod is movably connected to the loading rack. The hanging rod is provided with a number of hooks for hanging workpieces to be electroplated. Brackets are erected on both sides of the production tank, and a traveling crane moving along the length direction of the brackets is arranged above the production tank on the brackets. The traveling crane is provided with a clamping mechanism for clamping the hanging rod, and a hoisting mechanism for driving the clamping mechanism to lift and lower is arranged on the traveling crane.

[0003] Through the cooperation of the hanging rod, the loading rack, the loading cart, the clamping mechanism, the hoisting mechanism and the traveling crane, while realizing the feeding of the workpieces to be electroplated, it helps to reduce the operations during manual feeding, thus achieving the effect of saving time and effort; and it helps to improve the processing efficiency.

[0004] When electroplating the workpieces, after all the hanging rods on the loading rack are filled with the workpieces to be electroplated, the worker then pushes the loading cart to the feeding side of the production tank. The hoisting mechanism drives the clamping mechanism to move vertically downward to clamp the hanging rod, and then the hoisting mechanism drives the clamping mechanism to move vertically upward to above the production tank, and then it is conveyed by the traveling crane.

[0005] When the workpiece to be electroplated moves above a certain treatment tank each time, the hoisting mechanism drives the hanging rod to move vertically downward so that the workpiece to be electroplated is immersed in the treatment tank. After being treated in this treatment tank, the hoisting mechanism drives the hanging rod to move vertically upward to leave this treatment tank. Through the cooperation of the traveling crane and the hoisting mechanism, after electroplating is completed, the traveling crane drives the electroplated workpiece to move to the discharging side of the production tank, and a discharging mechanism is used for discharging.

[0006] Therefore, since the hoisting mechanism corresponds to a batch of workpieces, it can only carry out electroplating for the next batch after the workpieces of this batch are electroplated and discharged, so the production efficiency is not high. Summary of the Invention

[0007] In view of this, the purpose of the present invention is to provide an anodic oxidation test production line for aluminum surface treatment to achieve the purpose of improving production efficiency.

[0008] To solve the above technical problems, the technical solution of the present invention is: an anodic oxidation test production line for aluminum surface treatment, including a reaction tank, a track, a conveying rack, and a support frame for hanging workpieces. The track is fixed on the side wall of the reaction tank, and the length direction of the track is parallel to the length direction of the reaction tank. The conveying rack is driven by a power motor and moves along the length direction of the track. The conveying rack straddles the reaction tank. A plurality of production tanks are provided on the reaction tank, and support blocks are connected to the upper edge of the reaction tank corresponding to the production tanks. A vertically arranged slide rail is fixedly connected to the side wall of the conveying rack, and a cross bar is slidably connected to the slide rail. A driving mechanism for driving the cross bar to move along the slide rail is provided on the conveying rack. The cross bar is connected to a support plate, and after the cross bar moves down, the support frame is supported by the support block and the support frame is separated from the support plate.

[0009] To implement the above technical solution, hang the first batch of workpieces on the support frame, support the support frame through the support plate, move the conveying rack along the length direction of the track to make the support frame correspond to a production tank, the driving mechanism makes the cross bar move down, so that the support frame is supported by the support block and the support frame is separated from the support plate; at this time, the second batch of workpieces can be hung on another support frame. Similarly, the support frame on the conveying rack can be made to correspond to another production tank, and the cross bar can be moved down through the driving mechanism. This support frame is supported by the support block. At this time, the second batch of workpieces is immersed in the production tank, so that multiple batches of workpieces can be produced simultaneously to achieve the purpose of improving production efficiency.

[0010] As a preferred solution of the present invention, a V-shaped groove is provided on the support block, a fixing block is connected to the support frame, and a fixing inclined surface is provided on the fixing block. The fixing block is placed on the support block and the fixing inclined surface is attached to the inner wall of the V-shaped groove.

[0011] To implement the above technical solution, the cross bar moves down, so that the fixing block is placed on the support block and the fixing inclined surface is attached to the inner wall of the V-shaped groove, so that the connection between the support frame and the support block is more stable, and the support frame is not easily moved along the length direction of the reaction tank, so that the workpieces have better production quality during oxidation, coloring, and sealing operations.

[0012] As a preferred solution of the present invention, the driving mechanism includes a driving motor, a fixed shaft, a connecting belt, and a connecting rod. The connecting rod is fixed on the cross bar and forms a connection area with the cross bar. The driving motor is fixed in the conveying rack and drives the fixed shaft to rotate. One end of the connecting belt is fixed on the fixed shaft, and the other end of the connecting belt bypasses the connection area and is fixed on the surface of the connecting belt.

[0013] To implement the above technical solution, the drive motor is started, and the fixed shaft rotates, causing the connecting belt to wind around the fixed shaft, so that the connecting belt drives the cross bar to move upward along the length direction of the slide rail through the connecting rod; similarly, when the connecting belt unwinds from the fixed shaft, the cross bar can move downward due to the action of gravity; and since the drive motor is located above the cross bar and far from the production tank, the drive motor is not easily damaged.

[0014] As a preferred embodiment of the present invention, mounting holes are provided on the support plate, a connecting motor is fixedly connected in the mounting holes, a straight pipe is threadedly connected to the rotating shaft of the connecting motor, a straight groove for passing through the straight pipe is provided on the side wall of the support frame, and the straight pipe is slidably connected to the inner wall of the mounting hole.

[0015] To implement the above technical solution, the support frame is supported by the support plate. The connecting motor is turned on to make the rotating shaft rotate forward and the straight pipe penetrate into the straight groove, so that the support frame can be stably placed on the support plate and is not easily separated from the support plate; after the fixed block on the support frame is placed on the support block, the rotating shaft rotates reversely to draw the straight pipe out of the straight groove, and then the support plate is moved downward to separate the support plate from the support frame.

[0016] As a preferred embodiment of the present invention, a mounting groove is provided on the upper surface of the production tank, the support block is slidably connected in the mounting groove, an elastic member is provided between the inner wall of the mounting groove and the support block, a vertical hole is provided on the bottom wall of the mounting groove along the vertical direction, a connecting shaft connected to the support block is penetrated in the vertical hole, a stirring shaft is rotatably connected in the production tank, stirring paddles are fixedly connected to the outer wall of the stirring shaft, and the connecting shaft moves downward with the support block and rotates the stirring shaft through a transmission assembly.

[0017] To implement the above technical solution, the cross bar moves downward, and the workpiece is immersed in the production tank. Then the support frame is placed on the support block. Since there are many workpieces on the support frame, it has a large mass. The support frame applies a downward pressure on the support block, and the support block moves downward along the mounting groove. The connecting shaft moves downward synchronously with the support block and rotates the stirring shaft through the transmission assembly. The stirring paddles stir the cleaning liquid in the production tank. The flowing cleaning liquid can facilitate the peeling of the oxide film on the workpiece and the removal of oil stains from the surface of the workpiece, and also enhance the contact between the cleaning liquid and the surface of the workpiece, shorten the cleaning time, and improve the cleaning efficiency; when the cross bar moves upward, the support block moves upward under the elastic force of the elastic member. At this time, the stirring paddles rotate again to make the cleaning liquid flow again. After the support frame is separated from the support block, the workpiece is taken out of the production tank, achieving the effect of improving the production quality and production efficiency.

[0018] As a preferred embodiment of the present invention, the conduction assembly includes a slide bar and a spiral groove. The slide bar is fixed to the outer wall of the connecting shaft, and the spiral groove is formed on the side wall of the stirring shaft. The slide bar is slidably connected in the spiral groove.

[0019] To achieve the above technical solution, the connecting shaft moves along its own length direction, the slide bar moves synchronously with the connecting shaft, and the slide bar abuts against the inner wall of the spiral groove, so that the stirring shaft drives the stirring paddle to rotate.

[0020] As a preferred embodiment of the present invention, the support frame includes a cross beam. The cross beam is provided with a fixing hole along its own length direction, and a connecting hole communicating with the fixing hole is formed on the side wall of the cross beam. A plurality of connecting holes are arranged along the length direction of the cross beam. An inclined plate is hinged in the fixing hole, and a fixing area is formed between the inclined plate and the bottom wall of the fixing hole. The cross beam is connected to the workpiece through a positioning member. One end of the positioning member binds the workpiece, and the other end of the positioning member passes through the connecting hole and is placed in the fixing area.

[0021] To achieve the above technical solution, bind one end of the positioning member to the workpiece, insert the other end of the positioning member into the fixing area, make the lower end of the inclined plate abut against the upper surface of the positioning member. Due to the gravity of the workpiece, the positioning member has a tendency to be pulled out from the connecting hole. The inclined plate presses the positioning member through the friction force between the inclined plate and the positioning member, so that the positioning member cannot be separated from the inclined plate, thus making the installation of the workpiece more convenient.

[0022] As a preferred embodiment of the present invention, a slide hole is formed on the side wall of the cross beam. A pressing rod is slidably connected in the slide hole. A screw tube is rotatably connected to the inner wall of the fixing hole. The pressing rod passes through the screw tube and is threadedly connected to the screw tube. The outer wall of the screw tube is connected to the inclined plate through a pull rope.

[0023] To achieve the above technical solution, after the workpiece is processed, apply pressure to the pressing rod to make the screw tube rotate forward. The pull rope is wound around the screw tube and the pull rope drives the inclined plate to flip, so that the inclined plate is separated from the positioning member. Due to the gravity of the workpiece, all the workpieces can fall off the support frame at the same time, thus eliminating the process of workers taking the workpieces one by one and greatly improving the production efficiency. After releasing the pressing rod, the screw tube can rotate reversely due to the gravity of the inclined plate, so that the pressing rod can reset itself.

[0024] As a preferred embodiment of the present invention, a top hole is formed on the upper surface of the cross beam. A top rod is slidably connected in the fixing hole. A rack is fixedly connected to the outer wall of the top rod. A gear meshing with the rack is fixedly connected to the outer wall of the screw tube. The top rod is used to extend out of the top hole.

[0025] To implement the above technical solution, during the rotation of the solenoid, the gear rotates synchronously with the solenoid, the rack drives the ejector rod to extend from the top hole, and the ejector rod jacks up the workpiece hanging on the crossbeam, creating a gap between the workpiece and the crossbeam. By passing a rod through the gap, all the workpieces hanging on the crossbeam can be removed at once, thus further improving the production quality.

[0026] The present invention also discloses a method for anodic oxidation test of aluminum surface treatment, including an anodic oxidation test production line for aluminum surface treatment, which comprises the following steps: S1. Connect one end of the positioning member to the workpiece, pass the other end of the positioning member through the connection hole and press it against the inclined plate to fix the positioning member. S2. Place the support frame on the support plate, move the conveying frame along the length direction of the reaction tank and immerse the workpieces into each production tank in sequence to complete the processing of the workpieces. S3. Apply pressure to the pressing member, and all the workpieces can be made to fall off the support frame simultaneously.

[0027] To implement the above technical solution, after the workpieces are processed, applying a downward pressure to the pressing member can make all the workpieces fall off, thus greatly improving the production efficiency.

[0028] In summary, the present invention has the following beneficial effects: 1. After the workpieces are immersed in the production tank, applying a downward pressure to the support block through the support frame causes the stirring paddle to rotate, making the cleaning liquid in the production tank flow, so as to improve the cleaning efficiency of the workpieces and thus improve the production efficiency. 2. By moving the conveying frame, multiple batches of workpieces can be processed in the reaction tank simultaneously, further improving the production efficiency. 3. After the workpieces are processed by the anodic oxidation process, applying pressure to the pressing rod can make all the positioning members fall off the crossbeam, enabling all the workpieces to be collected at one time, further improving the production efficiency. 4. When pressure is applied to the pressing rod, the ejector rod extends from the top hole, and the ejector rod jacks up the workpiece hanging on the crossbeam, creating a gap between the workpiece and the crossbeam. By passing a rod through the gap, all the workpieces can be removed at once, further improving the production efficiency. 5. Inserting the straight pipe into the straight groove makes the connection between the support frame and the support plate more stable, so that the support frame is not easily separated from the support plate during the up and down movement, improving the safety. 6. When the fixing block on the support frame is placed on the support block, the support block bears the total weight of the support frame and the cross bar. At this time, the deformation of the elastic member is relatively large. When the straight pipe is drawn out from the straight groove, the support block only bears the total weight of the support frame. Therefore, the deformation of the elastic member becomes smaller. Through the elastic force of the elastic member, the support frame can vibrate up and down repeatedly on the support block, so that the stirring paddle can keep rotating for a period of time, and at the same time, the cleaning efficiency of the workpiece in the production tank can be improved, so as to improve the production efficiency.

The cleaning tank 41 includes a pickling tank 411, an alkali washing tank 412, and a neutralization tank 413 arranged in sequence.

[0035] The pickling tank 411 contains sulfuric acid, the alkali washing tank 412 contains sodium hydroxide, the neutralization tank 413 contains sulfuric acid and a neutralizing agent, the oxidation tank 42 contains sulfuric acid, the coloring tank 43 contains a coloring stabilizer and stannous sulfate, and the sealing tank 44 contains a chemical sealing agent.

[0036] The workpiece is immersed in the pickling tank 411 to remove the oxide film, immersed in the alkaline cleaning tank 412 to remove oil stains, immersed in the neutralizing tank 413 to adjust the pH value, immersed in the oxidation tank 42 to form an oxide film on the surface of the workpiece, and immersed in the coloring tank 43 to endow the anodic oxidation film with color, improving the decoration and functionality of the workpiece. Finally, the workpiece is immersed in the sealing tank 44 to seal the pores of the anodic oxidation film, improving the corrosion resistance, wear resistance, stain resistance and weather resistance of the oxide film, and fixing the coloring effect, so that the workpiece has extremely high production quality.

[0037] A support block 5 is connected to the upper edge of the reaction tank 1, and the support block 5 corresponds to the production tank 4.

[0038] On the side wall of the conveying rack 2, a vertically arranged slide rail 61 is fixedly connected, and a horizontally arranged cross bar 62 is slidably connected to the slide rail 61. A driving mechanism 7 for driving the cross bar 62 to move along the slide rail 61 is arranged on the conveying rack 2.

[0039] The driving mechanism 7 includes a driving motor 71, a fixed shaft 72, a connecting belt 73, and a connecting rod 74. The connecting rod 74 is fixed to the cross bar 62 and forms a connection area with the cross bar 62. The length direction of the connecting rod 74 is parallel to the length direction of the cross bar 62. The driving motor 71 is fixed inside the conveying rack 2 and drives the fixed shaft 72 to rotate. One end of the connecting belt 73 is fixed to the fixed shaft 72, and the other end of the connecting belt 73 bypasses the connection area and is fixed to the surface of the connecting belt 73. The driving motor 71 is a servo motor.

[0040] When the driving motor 71 is started, the fixed shaft 72 rotates forward, and the connecting belt 73 is wound around the fixed shaft 72, so that the cross bar 62 can move upward. Similarly, when the fixed shaft 72 rotates reversely, the fixed shaft 72 unwinds the connecting belt 73, and due to the gravity, the cross bar 62 moves downward along the slide rail 61.

[0041] Two support plates 75 are connected to the cross bar 62. An upper clamping plate 76 and a lower clamping plate 77 are respectively arranged on the upper and lower sides of the cross bar 62. The lower clamping plate 77 is fixedly connected to the support plate 75, and the upper clamping plate 76 and the lower clamping plate 77 are fixedly connected by fixing bolts to adjust the distance between the two support plates 75.

[0042] After the cross bar 62 moves downward, the support frame 3 is supported by the support block 5 and the support frame 3 is separated from the support plate 75.

[0043] A horizontally arranged V-shaped groove 51 is formed in the support block 5. A fixing block 8 is fixedly connected to the outer wall of the support frame 3. A fixing inclined surface 81 is formed in the fixing block 8, and the two fixing inclined surfaces 81 are arranged in a V shape. The fixing block 8 is placed on the support block 5 and the fixing inclined surface 81 is attached to the inner wall of the V-shaped groove 51.

[0044] An installation groove 91 is provided on the upper surface of the cleaning tank 41. The support block 5 is slidably connected in the installation groove 91. An elastic member 92 is provided between the inner wall of the installation groove 91 and the support block 5. The elastic member 92 is a spring.

[0045] A vertical hole 93 is provided on the bottom wall of the installation groove 91. A connecting shaft 94 fixedly connected to the lower surface of the support block 5 is inserted into the vertical hole 93. The connecting shaft 94 is above the cleaning liquid in the cleaning tank 41.

[0046] A vertically arranged stirring shaft 95 is rotatably connected to the inner wall of the cleaning tank 41. Stirring paddles 96 are fixedly connected to the outer wall of the stirring shaft 95. The stirring paddles 96 and the stirring shaft 95 are integrally arranged and are both made of glass fiber reinforced polypropylene. The stirring paddles 96 are immersed in the cleaning liquid.

[0047] The workpiece is immersed in the cleaning liquid. Subsequently, the support frame 3 is placed on the support block 5. The support block 5 moves downward under the pressure of the support frame 3. The connecting shaft 94 moves downward with the support block 5 and drives the stirring shaft 95 to rotate through the transmission assembly 97.

[0048] The transmission assembly 97 includes a slide bar 971 and a spiral groove 972. The slide bar 971 is fixed to the outer wall of the connecting shaft 94. The axis of the slide bar 971 is perpendicular to the axis of the connecting shaft 94. The spiral groove 972 is provided on the side wall of the stirring shaft 95. The connecting shaft 94 penetrates into the stirring shaft 95. The slide bar 971 is slidably connected in the spiral groove 972.

[0049] When the connecting shaft 94 moves downward, the slide bar 971 abuts against the inner wall of the spiral groove 972, causing the stirring shaft 95 to drive the stirring paddles 96 to rotate. When the stirring paddles 96 rotate, the cleaning liquid can flow, thereby improving the cleaning efficiency of the workpiece in the cleaning tank 41.

[0050] The workpiece can improve the efficiency of removing the oxide film in the pickling tank 411; the workpiece can improve the efficiency of removing oil stains in the alkaline cleaning tank 412; the workpiece can improve the efficiency of adjusting the pH value in the neutralization tank 413. Thereby greatly improving the production efficiency.

[0051] Connect the first batch of workpieces to the first support frame 3. Through the transmission of the conveying frame 2, when the first batch of workpieces is in the alkaline cleaning tank 412. Connect the second batch of workpieces to the second support frame 3. Through the transmission of the conveying frame 2, the second batch of workpieces can be in the pickling tank 411, so that multiple batches of workpieces can be processed simultaneously, further improving the production efficiency.

[0052] A horizontally arranged mounting hole 300 is formed in the support plate 75. A horizontally arranged connecting motor 301 is fixedly connected in the mounting hole 300. A straight pipe 302 is threadedly connected to the rotating shaft of the connecting motor 301. The straight pipe 302 is also horizontally arranged. A straight groove 303 for passing through the straight pipe 302 is formed in the side wall of the support frame 3. The straight groove 303 is horizontally arranged. The straight pipe 302 is slidably connected to the inner wall of the mounting hole 300. The width of the straight groove 303 is greater than the outer diameter of the straight pipe 302.

[0053] A strip-shaped sliding groove 304 is formed in the outer wall of the straight pipe 302. The length direction of the sliding groove 304 is parallel to the length direction of the straight pipe 302. A slider 305 is fixedly connected to the inner wall of the mounting hole 300. The slider 305 is slidably connected in the sliding groove 304.

[0054] The support frame 3 is placed on the support plate 75. The connecting motor 301 is turned on to make the straight pipe 302 penetrate into the straight groove 303. By the contact between the outer wall of the straight pipe 302 and the inner wall of the straight groove 303, when the support frame 3 moves up and down with the support plate 75, the support frame 3 is more stable on the support plate 75.

[0055] When the fixed block 8 on the support frame 3 contacts the support block 5, the connecting belt 73 is continuously released to make the support block 5 bear the total weight of the support frame 3 and the cross bar 62. At this time, the deformation amount of the elastic member 92 is relatively large. After the support frame 3 is placed stably, the connecting motor 301 is turned on to draw out the straight pipe 302 from the straight groove 303. Under the elastic force of the elastic member 92, the support frame 3 can move up and down repeatedly on the support block 5 to keep the stirring paddle 96 rotating for a period of time. At the same time, the cleaning efficiency of the workpiece in the cleaning tank 41 can be improved, so as to improve the production efficiency.

[0056] The support frame 3 includes a cross beam 100. The cross beam 100 straddles the reaction tank 1 and is horizontally arranged. A fixing hole 101 is formed in the cross beam 100 along its length direction. A connecting hole 102 communicating with the fixing hole 101 is formed in the side wall of the cross beam 100. A plurality of connecting holes 102 are arranged along the length direction of the cross beam 100.

[0057] An inclined plate 103 is hinged in the fixing hole 101. One connecting hole 102 corresponds to one inclined plate 103. A fixing area is formed between the inclined plate 103 and the bottom wall of the fixing hole 101. The cross beam 100 is connected to the workpiece through a positioning member. One end of the positioning member binds the workpiece. The other end of the positioning member passes through the connecting hole 102 and is placed in the fixing area. Through the friction force between the inclined plate 103 and the positioning member, the positioning of the positioning member is realized, and at the same time, the workpiece is hung on the support frame 3. The positioning member is a wire.

[0058] A sliding hole 200 is formed in the side wall of the cross beam 100, and a pressing rod 201 is slidably connected in the sliding hole 200. A guiding rod 202 is fixedly connected to the outer wall of the pressing rod 201, and the length direction of the guiding rod 202 is parallel to the length direction of the pressing rod 201. A guiding groove 203 is formed in the inner wall of the sliding hole 200, and the guiding rod 202 is slidably connected in the guiding groove 203.

[0059] A screw tube 204 is rotatably connected to the inner wall of the fixing hole 101, and the pressing rod 201 penetrates into the screw tube 204 and is threadedly connected to the screw tube 204.

[0060] The outer wall of the screw tube 204 is connected to the inclined plate 103 through a pulling rope 205.

[0061] After the workpiece is processed by the anodic oxidation process, a pressure is applied to the pressing rod 201 to rotate the screw tube 204 forward, and the pulling rope 205 is wound around the screw tube 204. The pulling rope 205 applies a pulling force to the inclined plate 103 to separate the inclined plate 103 from the positioning member. At this time, by the action of gravity, all the positioning members can be separated from the cross beam 100, and the unloading is completed at one time, further improving the production efficiency.

[0062] Then the pressing rod 201 is released, and due to the gravity of the inclined plate 103, the screw tube 204 rotates reversely, and then the pressing rod 201 is reset.

[0063] A top hole 206 is formed in the upper surface of the cross beam 100, and a limiting groove 207 is formed in the outer wall of the cross beam 100. The top hole 206 is located in the limiting groove 207.

[0064] A top rod 208 is slidably connected in the fixing hole 101, and a rack 209 is fixedly connected to the outer wall of the top rod 208. A gear 210 meshing with the rack 209 is fixedly connected to the outer wall of the screw tube 204, and the top rod 208 is used to extend out of the top hole 206.

[0065] Some workpieces are relatively long and are hung in the limiting groove 207 through hooks.
