Description

Technical Field

[0001] This invention relates to the field of metal etching technology, and in particular to an electrochemical etching surface processing apparatus for metal nameplates. Background Technology

[0002] Electrochemical etching is a technique that uses an electrolyte solution and an electric current to etch the surface of a metal. During the electrochemical etching process, the metal is immersed in an electrolyte solution and then connected to a power source through electrodes. When the current passes through the electrolyte solution and the metal surface, it causes a chemical reaction on the metal surface, thereby etching out the desired shape or pattern. The advantage of this technique is that it can etch various shapes and patterns with high precision and can be performed without damaging the metal surface. When performing electrochemical etching, appropriate protective measures are required to avoid harm to the human body from the electrolyte solution and the current.

[0003] Currently, before electrochemical etching, different patterns are drawn on the surface of metal nameplates using paint according to requirements. After the pattern is drawn, it is connected to the anode and placed in the electrolyte connected to the cathode. When the current passes through the electrolyte solution and the metal surface, it causes a chemical reaction on the metal surface, thereby etching out the desired shape or pattern. However, when there is rust or oxide layer on the surface of the metal nameplate, it will have the same isolation effect as the paint, which will slow down or even prevent the chemical reaction on the metal surface, thus affecting the quality of the etching process on the surface of the metal nameplate. In addition, the traditional manual polishing and cleaning method for the surface of metal nameplates is inefficient and leads to high costs.

[0004] Therefore, there is a need to provide an electrochemical etching surface processing apparatus for metal nameplates, which aims to solve the above problems. Summary of the Invention

[0005] The main objective of this invention is to provide an electrochemical etching surface processing apparatus for metal nameplates, which can effectively solve the problems in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] An electrochemical etching surface processing apparatus for metal nameplates includes an etching machine base. Two support plates are symmetrically fixedly connected to the top of the etching machine base. An electrolytic cell is formed on the upper surface of the middle part of the etching machine base. Support seats are fixedly connected to the tops of the two support plates. A motor is fixedly connected to the outer wall of the support seat. A movable seat is slidably installed on the inner side of the support seat away from the motor. A first lead screw is horizontally and rotatably connected through the inner side of the support seat. The first lead screw is fixedly connected to the output shaft of the motor. The movable seat is threaded onto the outer side of the first lead screw. The movable seat is close to the motor. A double-rod hydraulic cylinder is fixedly connected to the upper surface of one end of the machine. The two output shafts of the double-rod hydraulic cylinder pass through the movable seat and are fixedly connected to the clamping seat. The bottom inner side of the clamping seat is provided with a clamping component for clamping metal nameplates. The bottom of the support seat is provided with a drive component for changing the clamping component. A wedge block is slidably connected to the inner side of the support seat away from the motor. Two grinding blocks are symmetrically fixedly connected to the lower surface of the wedge block. The bottom of the two grinding blocks is arc-shaped on the side that is close to each other. A grinding component for external grinding and cleaning is installed on the support plate away from the motor.

[0008] The polishing assembly includes two polishing blocks 2 fixedly connected to the support plate, and a polishing plate 1 and a polishing plate 2 fixedly connected between the two polishing blocks 2. The polishing plate 2 is located at the top of the polishing plate 1. Two polishing blocks 3 are symmetrically fixedly connected to the ends of the polishing plate 1 and the polishing plate 2 away from the support plate. Two fixing plates are fixedly connected to the ends of the two polishing blocks 3 away from the support plate.

[0009] A spring is fixedly connected between the upper surface of the second grinding plate and the wedge block, and a groove adapted to the first roller screw is provided on the upper surface of the wedge block.

[0010] As a further improvement to the above solution, a paint tank is fixedly installed on the upper surface of the etching machine base. A paint roller for applying different pattern coatings is horizontally arranged on the inner side of the paint tank. An installation shaft is fixedly connected to the inner side of the paint roller. Two ear plates are symmetrically fixedly connected to the upper surface of the paint tank. The two ends of the installation shaft are respectively rotatably installed on the side of the ear plate that is close to the paint tank. The top end of the paint roller is flush with the upper surface of the bottom fixing plate.

[0011] As a further improvement to the above solution, the clamping assembly includes four clamping rods slidably connected to the inner side of the bottom of the clamping seat. The four clamping rods are divided into two groups of two, and the two groups of clamping rods are symmetrically distributed about the horizontal center line of the support seat. A clamping block is fixedly connected to the side of the two groups of clamping rods that are close to each other.

[0012] As a further improvement to the above solution, the drive assembly includes two gears rotatably mounted on the inner side of the top of the clamping seat. The ends of the two gears rotatably pass through the clamping seat. A ball screw is fixedly mounted on the inner side of the gears rotatably. A movable block is slidably connected to the inner side of the middle of the clamping seat. The bottom end of the ball screw passes through the clamping seat and is threaded to the inner side of the movable block. Two guide rails are fixedly connected to the lower surface of the support seat. The two guide rails are symmetrically distributed about the horizontal longitudinal center line of the support seat. The bottom ends of the two guide rails are slidably connected to mounting strips. Two racks are fixedly connected to the adjacent sides of the two mounting strips.

[0013] As a further improvement to the above scheme, one set of two clamping rods is connected to a bidirectional lead screw two via an inner thread, and another set of two clamping rods is connected to a bidirectional lead screw one via an inner thread. A support rod one is fixedly connected to the inner side of the bidirectional lead screw one, and a support rod two is fixedly connected to the inner side of the bidirectional lead screw two. Two gears two are symmetrically fixedly connected to the outer end of the support rod one, and two gears three are symmetrically fixedly connected to the outer end of the support rod two. A rack three is fixedly connected to the side of the movable block near the bidirectional lead screw two, and a rack two is fixedly connected to the side of the movable block near the bidirectional lead screw one.

[0014] As a further improvement to the above solution, four partitions are fixedly connected to the inner wall of the clamping seat. The four partitions are divided into two groups of two, and the two groups of partitions are symmetrically distributed about the movable block. The side of the two groups of partitions that are close to each other is in contact with the outer wall of the movable block. Both support rod one and support rod two are rotatably connected to the inner side of the partitions.

[0015] As a further improvement to the above solution, two limiting grooves are symmetrically opened on the inner side wall of the support base away from the motor, and two limiting blocks are symmetrically fixedly connected on the outer side wall of the movable base, with both limiting blocks slidably connected to the inner side of the limiting groove.

[0016] As a further improvement to the above solution, two arc-shaped grooves are symmetrically formed on the upper surface of the paint tank, and the two arc-shaped grooves extend into the inner side of the paint tank from one end to the other.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The motor drives the movable seat to press the wedge block downwards, so that the wedge block can polish the front and back surfaces of the metal nameplate. During the polishing process, the metal nameplate, which is held by the clamping component, can be polished on the upper and lower surfaces of the metal nameplate in time by polishing plate one and polishing plate two, and polishing at both ends of the metal nameplate by polishing block three. This makes it easier to polish the outer surface of the metal nameplate and ensures the overall polishing effect of the metal nameplate, avoiding the impact of incomplete polishing on the quality of electrochemical etching.

[0019] 2. Two sets of clamping rods can be used to cross-clamp the metal nameplate, which can be used to replace the clamping during the moving and grinding process, so that the metal nameplate can always move and be ground. In addition, during the cross-clamping process, the power for alternating clamping is mainly provided by the meshing connection of gear one and rack one, which ensures the stability of the clamping process.

[0020] 3. The paint tank allows for paint storage, enabling the rolling paint wheel to apply the corresponding pattern to the lower surface of the metal nameplate, preventing the pattern portion on the metal nameplate from being electrolyzed in the electrolyte, thus achieving the etching of different patterns on the metal nameplate.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0041] Please see Figures 1 to 8As shown, this invention provides an embodiment: an electrochemical etching surface processing device for metal nameplates, including an etching machine base 1, two support plates 2 symmetrically fixedly connected to the top of the etching machine base 1, an electrolytic cell formed on the upper surface of the middle part of the etching machine base 1, support seats 4 fixedly connected to the top of the two support plates 2, a motor 3 fixedly connected to the outer wall of the support seat 4, a movable seat 601 slidably installed on the inner side of the end of the support seat 4 away from the motor 3, a roller screw 605 horizontally and laterally connected to the inner side of the support seat 4, the output shaft of the motor 3 fixedly connected to the roller screw 605, and the movable seat 601 threadedly installed on the outer side of the roller screw 605. A double-rod hydraulic cylinder 9 is fixedly connected to the upper surface of the end near the motor 3. The two output shafts of the double-rod hydraulic cylinder 9 pass through the movable seat 601 and are fixedly connected to the clamping seat 602. The bottom inner side of the clamping seat 602 is provided with a clamping component for clamping the metal nameplate. The bottom of the support seat 4 is provided with a drive component for changing the clamping component. A wedge block 701 is slidably connected to the inner side of the support seat 4 away from the motor 3. Two grinding blocks 702 are symmetrically fixedly connected to the lower surface of the wedge block 701. The bottom of the two grinding blocks 702 is arc-shaped on the side that is close to each other. A grinding component for grinding and cleaning the outside is installed on the support plate 2 on the side away from the motor 3.

[0042] Furthermore, the etching machine base 1, support base 4 and two support plates 2 are combined to form the support frame of the device. Then, the movable seat 601 is connected by a roller screw 605, so that the motor 3 can drive the movable seat 601 to move. The movable seat 601 can drive the clamping seat 602 to move while moving up and down through the double-rod hydraulic cylinder 9, so as to drive the metal nameplate into the electrolyte for electrolysis.

[0043] Preferably, the grinding assembly includes two grinding blocks 1003 fixedly connected to the support plate 2. Grinding plate 1001 and grinding plate 1002 are fixedly connected between the ends of the two grinding blocks 1003 away from the support plate 2. Grinding plate 1002 is located at the top of grinding plate 1001. Two grinding blocks 1004 are symmetrically fixedly connected to the ends of grinding plate 1001 and grinding plate 1002 away from the support plate 2. Two fixing plates 1005 are fixedly connected to the ends of the two grinding blocks 1004 away from the support plate 2. A spring 703 is fixedly connected between the upper surface of grinding plate 1002 and wedge block 701. The upper surface of wedge block 701 has a groove adapted to the lead screw 605.

[0044] Furthermore, during the movement of the metal nameplate, it is first polished and cleaned on the upper and lower surfaces by polishing plate 1001 and polishing plate 2 1002, and then polished and cleaned at both ends by polishing block 3 1004. When the wedge block 701 is pressed downward by the movable seat 601, the front and rear ends of the metal nameplate can be polished and cleaned by polishing block 1 702. The groove prevents the movement of the wedge block 701 from being affected by the roller screw 1 605.

[0045] Preferably, a paint tank 501 is fixedly installed on the upper surface of the etching machine base 1. A paint roller 504 for applying different pattern coatings is horizontally arranged on the inner side of the paint tank 501. An installation shaft 503 is fixedly connected to the inner side of the paint roller 504. Two ear plates 502 are symmetrically fixedly connected to the upper surface of the paint tank 501. Both ends of the installation shaft 503 are rotatably installed between the ear plates 502 and the paint tank 501. The top end of the paint roller 504 is flush with the upper surface of the bottom fixing plate 1005.

[0046] Furthermore, the paint can be stored in the paint tank 501, and the paint roller 504 can be rotated and installed by the ear plate 502 and the mounting shaft 503. The paint roller 504 can apply the paint to the lower surface of the metal nameplate to form a pattern and prevent this part from being electrolyzed.

[0047] Preferably, the clamping assembly includes four clamping rods 1201 slidably connected to the inner side of the bottom of the clamping seat 602. The four clamping rods 1201 are divided into two groups of two. The two groups of clamping rods 1201 are symmetrically distributed about the horizontal center line of the support seat 4. A partition plate 1203 is fixedly connected to the side of the two groups of clamping rods 1201 that are close to each other.

[0048] Furthermore, the clamping assembly driven by the drive assembly can synchronize the two sets of clamping rods 1201. When one set of clamping rods 1201 moves towards each other to clamp the metal nameplate, the other set of clamping rods 1201 will move away from each other to release, so as to alternately clamp the metal nameplate.

[0049] Preferably, the drive assembly includes two gears 1101 rotatably mounted on the inner side of the top of the clamping seat 602. The ends of the two gears 1101 that are far apart pass through the clamping seat 602. A roller screw 1102 is fixedly mounted on the inner side of the gears 1101. A movable block 1103 is slidably connected to the inner side of the middle part of the clamping seat 602. The bottom end of the roller screw 1102 passes through the clamping seat 602 and is threaded to the inner side of the movable block 1103. Two guide rails 803 are fixedly connected to the lower surface of the support seat 4. The two guide rails 803 are symmetrically distributed about the horizontal longitudinal center line of the support seat 4. The bottom ends of the two guide rails 803 are slidably connected to the mounting strips 801. Two racks 802 are fixedly connected to the adjacent side of the two mounting strips 801. The racks 802 are adapted to the gears 1101.

[0050] Furthermore, when the clamping seat 602 drives the gear 1101 to contact the rack 802, the movement of the clamping seat 602 will drive the rack 802 to move synchronously. Only when the rack 802 moves to its maximum stroke on the guide rail 803 can the continued movement of the clamping seat 602 realize the rotation of the gear 1101 on the rack 802. At this time, the grinding plate 1001 can drive the roller screw 1102 to push the movable block 1103, realizing the alternating clamping of the metal nameplate by the two sets of clamping rods 1201.

[0051] Preferably, one set of two clamping rods 1201 is threadedly connected to a double-acting screw 1308 on its inner side, and the other set of two clamping rods 1201 is threadedly connected to a double-acting screw 1306 on its inner side. A support rod 1301 is fixedly connected to the inner side of the double-acting screw 1306, and a support rod 1307 is fixedly connected to the inner side of the double-acting screw 1308. Two gears 1303 are symmetrically fixedly connected to the outer end of the support rod 1301, and two gears 1305 are symmetrically fixedly connected to the outer end of the support rod 1307. A rack 1304 is fixedly connected to the side of the movable block 1103 near the double-acting screw 1308, and a rack 1302 is fixedly connected to the side of the movable block 1103 near the double-acting screw 1306.

[0052] Furthermore, when the movable block 1103 moves downward, it can drive the gear 1303 and gear 1305 respectively through the rack 2 1302 and rack 3 1304, so that the gear 3 1305 drives the support rod 2 1307 and drives the double-acting screw 2 1308 to rotate. The rotation of the rack 2 1302 drives the double-acting screw 1 1306 to rotate through the support rod 1 1301. The double-acting screw 1 1306 and double-acting screw 2 1308 rotate in opposite directions to realize the movement of the clamping rods 1201 at both ends in different directions.

[0053] Preferably, four partitions 1203 are fixedly connected to the inner wall of the clamping seat 602. The four partitions 1203 are divided into two groups of two. The two groups of partitions 1203 are symmetrically distributed about the movable block 1103. The side of the two groups of partitions 1203 that are close to each other is in contact with the outer wall of the movable block 1103. Support rod 1301 and support rod 2307 are rotatably connected to the inner side of the partitions 1203.

[0054] Furthermore, the four partitions 1203 can limit the maximum stroke of the two clamping rods 1201 while also enabling the rack 3 1304 and the support rod 1 1301 to rotate.

[0055] Preferably, two limiting grooves 603 are symmetrically opened on the inner side wall of the support base 4 away from the motor 3, and two limiting blocks 604 are symmetrically fixedly connected on the outer side wall of the movable base 601, and both limiting blocks 604 are slidably connected to the inner side of the limiting grooves 603.

[0056] Furthermore, by sliding the limiting block 604 inside the limiting groove 603, the stability of the movable seat 601 under the push of the roller screw 605 can be ensured.

[0057] Preferably, two arc-shaped grooves are symmetrically formed on the upper surface of the paint tank 501, and the adjacent ends of the two arc-shaped grooves extend into the inner side of the paint tank 501.

[0058] Furthermore, an arc-shaped groove is provided on the paint box 501, extending into the paint box 501, to facilitate storage, reduce the probability of paint spillage, and ensure overall cleanliness.

[0059] Based on the above preferred embodiments, the working principle of the present invention is as follows:

[0060] The initial steps are as follows: First, the operator starts the motor 3, rotating its output shaft clockwise and causing the lead screw 605 to rotate synchronously. Then, the lead screw 605, under the action of its thread, pushes the movable seat 601 to move. Because the limiting blocks 604 fixedly connected to both sides of the movable seat 601 are slidably installed inside the limiting groove 603, the movable seat 601 can move more stably under the threaded push of the lead screw 605 and fit against the inner wall of the support seat 4 near the motor 3. 1. During the movement, the movable seat 601 drives the clamping seat 602 mounted on the output shaft of the double-rod hydraulic cylinder 9 to move synchronously. During the movement of the clamping seat 602, it drives the gear 1101 to move synchronously. Since the rack 802 is meshed with the gear 1101, and the rotational force of the gear 1101 is greater than the moving force pushing the rack 802, the gear 1101 can push the rack 802 to move. When the rack 802 reaches the maximum stroke of the guide rail 803, the clamping seat 602 continues to move. Continuous movement causes gear 1101 to rotate under the limit of rack 1102. The rotating gear 1101 drives the roller screw 2 1102 to rotate. Under the action of the bottom thread, the roller screw 2 1102 can push the movable block 1103 downward, making the movable block 1103 move more smoothly under the limit of the four partitions 1203. The downward movement of the movable block 1103 not only drives gear 2 1303 to rotate counterclockwise through support rod 1301, but also through rack 3 13 04. The third gear 1305 is driven to rotate clockwise. The rotating gear 1303 drives the first support rod 1301, which is supported by the partition plates 1203 at both ends, to rotate. The rotating gear 1305 drives the second bidirectional lead screw 1308, which is supported by the partition plates 1203 at both ends, to rotate. Driven by the rotation of the first bidirectional lead screw 1306, the two clamping rods 1201 with their outer threads move towards each other. The rotation of the second bidirectional lead screw 1308 can drive the two clamping rods 1201 with their outer threads to move in opposite directions.

[0061] The working steps are as follows: First, the operator needs to insert the metal nameplate through the support plate 2 and the two grinding blocks 1003 into the space between the grinding plate 1001 and the grinding plate 1002. Then, the motor 3 is started and the output shaft rotates counterclockwise. The counterclockwise rotating lead screw 605 pushes the movable seat 601 to move under the action of the thread. The moving movable seat 601 maintains the stability of movement under the limit of the limit block 604 and the limit groove 603 and drives the double-rod hydraulic cylinder 9 to move. The moving double-rod hydraulic cylinder 9 drives its movable end. The connected clamping seat 602 moves synchronously. When the clamping seat 602 drives the gear 1101 to contact the rack 1102, the threaded connection between the fixed roller screw 1102 inside the gear 1101 and the movable block 1103 is relatively tight. Therefore, the rotational force of the gear 1101 is greater than the force of the rack 1102. Thus, the clamping seat 602 can push the rack 1102 to drive the mounting strip 801 to slide at the bottom end of the guide rail 803. When the mounting strip 801 moves to the rear end of the guide rail 803, the clamping seat 602... The continued movement of 02 will no longer push rack 802. Instead, with rack 802 fixed, the moving clamp 602 will drive gear 1101 to rotate, causing the ends of the two gears 1101 that are close to each other to rotate forward synchronously. The rotating gears 1101 at both ends can more stably push the movable block 1103 to move upward. The upward-moving movable block 1103 can drive gear 1305 to rotate counterclockwise through rack 3 1304, and can drive rack 2 1302 through gear 2 1303. Rotating clockwise, the rotating gear 3 1305 drives the double-acting lead screw 2 1308 to rotate via the support rod 2 1307, causing the two clamping rods 1201 on the double-acting lead screw 2 1308 to move towards each other to clamp the metal nameplate. The rotating gear 2 1303 drives the double-acting lead screw 1 1306 to rotate via the support rod 1 1301, causing the two clamping rods 1201 on the double-acting lead screw 1 1306 to move away from one end, so as to achieve clamping of the nameplate on a set of clamping rods 1201 at the bottom of the clamping seat 602.

[0062] Before the nameplate is clamped between the first grinding plate 1001 and the second grinding plate 1002, the backward movement of the movable seat 601 will push the wedge block 701 to move downward and compress the spring 703. The downward movement of the wedge block 701 will drive the two grinding blocks 702, so that the grinding blocks 702 can grind and clean the front and rear ends of the nameplate through the arc surface. When the movable seat 601 is reset, the wedge block 701 will also be reset under the elastic extension of the spring 703. At this time, the arc surface can make the nameplate move towards the electrolytic cell better under the drive of the movable seat 601.

[0063] After the nameplate is polished at both ends, the operator needs to restart the output shaft of motor 3 and rotate it counterclockwise. The counterclockwise rotation of the motor 3 output shaft pushes the movable seat 601 towards the motor 3 via the lead screw 605. During the movement of the movable seat 601, the wedge block 701 moves upward and resets under the elastic force of the spring 703. The nameplate moves towards the motor 3 under the clamping force of the two clamping rods 1201. Since the rack 802 and gear 1101 are engaged at this time, and the engagement force is greater than the sliding force of the mounting strip 801 on the guide rail 803, the movement of the movable seat 601 drives the mounting strip 801 forward. When the clamping block 1202 moves to the front end of the polishing plate 1001, the mounting strip 801 moves to the end of the guide rail 803 closest to the motor 3. At this point, the continued movement of the movable seat 601 will drive the gear... Gear 1101 rotates on rack 802, and the rotating gear 1101 drives the ball screw 1102 to push the movable block 1103 downward. The downward moving movable block 1103 drives the two clamping rods 1201 near the motor 3 to clamp the nameplate through the clamping block 1202. After clamping, the movable seat 601 continues to move and disengages from rack 802. At this time, the movable seat 601 can drive the nameplate through the coating roller 504. The coating is applied to the bottom surface of the nameplate by the rotating coating roller 504. When the movable seat 601 is in the preset position, the double-rod hydraulic cylinder 9 is activated to push the clamping seat 602 to drive the nameplate into the electrolytic tank on the etching machine base 1 for electrolysis. This automatically and conveniently completes the entire electrolysis operation, greatly improving the electrolysis efficiency of electrochemical etching of metal nameplates.
