Description

Technical Field

[0001] This invention relates to the field of etching technology, and more specifically to an automatic etching device for nameplates. Background Technology

[0002] A nameplate refers to a label or nameplate on equipment, which typically displays information such as rated voltage, current, power, serial number, model, manufacturer, production date, and power factor. This information is displayed using etching technology, a technique that utilizes a chemical reaction to remove unwanted portions of the material surface to create specific patterns or text.

[0003] During the etching process, the developed nameplate is fixed on a fixture. The fixture then places the nameplate into an etching chamber containing etching solution for etching. Alternatively, the fixture places the nameplate into the etching chamber and sprays the etching solution onto the nameplate to etch it. After etching is complete, the nameplate is removed and the remaining etching solution is wiped off before proceeding to the next step.

[0004] For example, the existing patent with application number 202221210061.7 and title "A High-Efficiency Multilayer Circuit Board Etching Device" discloses that "the inner cavity of the box is divided into an etching chamber and a purification chamber by a partition. An electric telescopic rod is fixedly installed on the top of the box. The electric telescopic rod can control the clamping component to lift and lower the fixed circuit board, so as to facilitate the insertion of the circuit board into the inorganic acid solution in the etching chamber for etching. After etching, the circuit board is lifted by controlling the electric telescopic rod and then the circuit board is rotated at high speed by the rotary motor to quickly remove the residual liquid on the circuit board."

[0005] In actual processing, it was found that existing etching technologies all have common drawbacks: To ensure both sides of the product to be etched, such as a nameplate, come into contact with the etching solution for simultaneous double-sided etching, existing technologies require a clamping and fixing mechanism to suspend and fix the nameplate before immersing it in the etching solution, or a spraying mechanism to simultaneously spray etching solution onto both sides of the nameplate. However, when the nameplate needs to be removed, the clamping mechanism must be released separately, inevitably increasing the number of steps. Furthermore, the pause between releasing the nameplate and removing the etching solution reduces efficiency due to the significant time difference. Additionally, before removing the nameplate, residual etching solution must be removed to prevent further corrosion. Existing technologies use a dedicated power mechanism, such as the rotary motor in the aforementioned patent, to drive the nameplate at high speed, using centrifugal force to remove the residual etching solution. However, a separate power mechanism increases the complexity of the equipment and maintenance costs. Therefore, a pressing technical problem needs to be solved: how to automatically remove the nameplate from the clamping mechanism and remove the residual etching solution on the nameplate without requiring a separate release operation of the clamping mechanism or adding an additional power mechanism for cleaning the residual etching solution on the nameplate, thereby improving work efficiency while reducing equipment complexity and maintenance costs. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic nameplate etching device to overcome the above-mentioned shortcomings of the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an automatic etching device for nameplates, comprising a base and a clamping mechanism for elastically holding the nameplates, wherein the clamping mechanism is fixedly mounted on a first shaft, the first shaft is rotatably mounted on a swing arm, and the swing arm is rotatably connected to the base; The swing arm is equipped with a baffle and two oppositely arranged absorbent cottons; A connecting gear is fixedly sleeved on the first shaft, and a half gear ring that meshes with the connecting gear is fixedly installed on the base, so that when the swing arm is rotated, the half gear ring drives the connecting gear and the first shaft to rotate. The rotation of the first shaft causes the nameplate to come into contact with the baffle, so that the nameplate is disengaged from the clamping mechanism. Then the nameplate slides down along the baffle and is squeezed between two absorbent cottons and pressed down by the clamping mechanism so that the etching solution on the nameplate is removed by the absorbent cotton.

[0008] The aforementioned automatic etching equipment for nameplates includes a clamping mechanism that is fixedly mounted on a first shaft. A mounting base is fixedly connected to the clamp via a connecting rod. A fixed clamping plate is fixedly mounted on the mounting base. A rotating clamping plate corresponding to the fixed clamping plate is elastically rotatably mounted on the mounting base. The nameplate is elastically clamped between the fixed clamping plate and the rotating clamping plate.

[0009] The aforementioned automatic etching equipment for nameplates further includes a cylinder fixedly connected to a mounting base via an extension rod, the cylinder abutting against the top of the nameplate.

[0010] In the aforementioned automatic etching equipment for nameplates, a fixed block is fixedly installed on the swing arm, a U-shaped plate is fixedly installed on the fixed block, a baffle is fixedly connected to the fixed block, two absorbent cottons are located inside the U-shaped plate, the baffle is located above the absorbent cottons, and the opposing surfaces of the two absorbent cottons are pressed against each other.

[0011] In the aforementioned automatic etching equipment for nameplates, a side groove is provided on the side of the baffle away from the fixing block. The side groove penetrates the top and bottom of the baffle. The side groove includes a guide groove and a limiting groove arranged sequentially and connected from the outside to the inside of the baffle. After the nameplate is separated from the clamping mechanism, its side passes through the guide groove and enters the limiting groove.

[0012] In the aforementioned automatic etching equipment for nameplates, a second shaft is fixedly mounted on the swing arm, a driven gear is fixedly sleeved on the second shaft, a drive motor is mounted on the base, and a third shaft is coaxially connected to the power output end of the drive motor. A drive gear that meshes with the driven gear is fixedly sleeved on the third shaft.

[0013] In the aforementioned automatic etching equipment for nameplates, a placement groove is provided on the base, and an etching tank for storing etching solution is placed in the placement groove.

[0014] In the aforementioned automatic etching equipment for nameplates, a pressing plate is elastically slidably inserted into the fixing block, and an arc-shaped plate is fixedly installed on the base. One end of the pressing plate is fixedly connected to the ends of two absorbent cottons, and the other end abuts against the outer arc-shaped surface of the arc-shaped plate. The end of the absorbent cotton away from the pressing plate is fixedly connected to the U-shaped plate, and the side of the two absorbent cottons that are far apart from each other is squeezed and adhered to the inner wall of the U-shaped plate.

[0015] In the aforementioned automatic etching equipment for nameplates, during the counterclockwise rotation of the extrusion plate driven by the swing arm, the outer arc surface of the arc plate pushes the extrusion plate toward the absorbent cotton to squeeze out the etching liquid inside the absorbent cotton.

[0016] In the aforementioned automatic etching equipment for nameplates, a movable receiving plate is slidably arranged on the etching tank. A toothed plate that meshes with a driven gear is fixedly installed on the movable receiving plate. An avoidance hole is opened on the movable receiving plate for the arc-shaped plate to pass through. During the process of the clamping mechanism rotating and pressing down on the nameplate so that the nameplate slides between two absorbent cottons, the driven gear drives the movable receiving plate to slide, so that the movable receiving plate supports the nameplate.

[0017] Beneficial effects: 1. In the above technical solution, the present invention provides an automatic etching device for nameplates. The clamping mechanism is configured as a rotating connection. The baffle abuts against the nameplate, allowing the nameplate to automatically detach from the clamping mechanism. Simultaneously, the inclined angle of the baffle allows the nameplate to slide downwards along the side of the baffle after detaching from the clamping mechanism. Ingeniously, the clamping mechanism abuts against the top of the nameplate after detaching from it, enabling the clamping mechanism to push the nameplate again. The rotational force of the clamping mechanism unexpectedly presses down on the nameplate, causing the nameplate to slide between two absorbent cotton pads, thereby achieving the effect of removing residual etching liquid from the nameplate. This eliminates the need for a pushing component and a power mechanism to provide power to the pushing component. Furthermore, there is no pause between the nameplate release operation and the etching liquid removal operation, with almost no time difference. The two actions are seamlessly connected and closely coordinated, resulting in higher work efficiency. It is evident that the present invention can automatically release the nameplate from the clamping mechanism and remove the residual etching solution on the nameplate without requiring a separate release operation of the clamping mechanism or adding an additional power mechanism for cleaning the residual etching solution on the nameplate. This improves work efficiency while reducing the complexity and maintenance cost of the equipment, effectively addressing the shortcomings of the prior art.

[0018] 2. This invention uses an elastically sliding extrusion plate and a fixedly installed arc-shaped plate that abuts against the extrusion plate. This allows the extrusion plate to cleverly squeeze the absorbent cotton during the counterclockwise rotation of the extrusion plate, thereby automatically squeezing out the etching solution from the absorbent cotton. This eliminates the need for separate cleaning of the etching solution from the absorbent cotton later, saving time and effort.

[0019] 3. During the clockwise rotation of the swing arm driven by the driven gear, this invention not only enables the release and removal of the nameplate and the cleaning of the etching solution on the nameplate, but also allows the moving plate to overlap with the nameplate in the vertical direction through the meshing of the driven gear and the toothed plate and the clockwise rotation of the absorbent cotton. This creates a technical effect where, when the nameplate is pressed down by the cylinder to the final stage, it falls onto the moving plate and is received and collected, preventing the nameplate from falling into the etching tank during the pressing process. With only one drive source required, this invention greatly improves the automation level of the equipment, ensures the working efficiency of the equipment, and significantly reduces the manufacturing cost and subsequent maintenance cost of the equipment.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] First embodiment: like Figure 1-20 As shown, an automatic nameplate etching device provided in this embodiment of the invention includes a base 1 and a clamping mechanism for elastically clamping a nameplate 26. The clamping mechanism is fixedly installed on a first shaft 501, and the first shaft 501 is rotatably installed on a swing arm 2. The swing arm 2 is rotatably connected to the base 1. The swing arm 2 is equipped with a baffle 7 and two oppositely arranged absorbent cottons 23; A connecting gear 5 is fixedly sleeved on the first shaft 501, and a half gear ring 3 that meshes with the connecting gear 5 is fixedly installed on the base 1 so that when the swing arm 2 is rotated, the half gear ring 3 drives the connecting gear 5 and the first shaft 501 to rotate. The rotation of the first shaft 501 causes the nameplate 26 to come into contact with the baffle 7, so that the nameplate 26 is released from the clamping mechanism. Then the nameplate 26 slides down along the baffle 7 between the two absorbent cottons 23, is squeezed and pressed down by the clamping mechanism so that the etching solution on the nameplate 26 is removed by the absorbent cottons 23.

[0025] The automatic etching equipment for nameplates provided in this embodiment is used for etching nameplates of specific sizes. During the process of removing the nameplate from the etching solution after etching, the equipment automatically releases the clamping mechanism from the nameplate and automatically removes any residual etching solution from the nameplate. In this embodiment, terms related to direction and position are relative to the accompanying drawings. Specifically, the base 1 is the supporting body, and a support plate 4 is fixedly installed on the base 1. One end of the swing arm 2 is rotatably connected to the support plate 4 so that the swing arm 2 can rotate up and down. The rotational power of the swing arm 2 is provided manually or by a drive mechanism. In this embodiment, it is preferred that the drive mechanism provides the power required for the rotation of the swing arm 2. The drive mechanism includes a second shaft 801 fixedly installed on the swing arm 2. The second shaft 801 is rotatably inserted into the support plate 4 to realize the rotatable connection between the swing arm 2 and the base 1. A driven gear 8 is fixedly sleeved on the second shaft 801, and the driven gear 8 is coaxial with the second shaft 801. A drive motor 10 is installed on the base 1. The drive motor 10 can rotate forward and reverse. The drive motor 10 is preferably a self-locking geared motor or a self-locking servo motor. Of course, the drive motor 10 can also be a non-self-locking type. The power output end of the drive motor 10 is coaxially connected to a third shaft 901. The third shaft 901 is fixedly connected to the power output end of the drive motor 10 or keyed. A drive gear 9 that meshes with the driven gear 8 is fixedly sleeved on the third shaft 901. The drive gear 9 is coaxial with the third shaft 901. Multiple bearing supports 11 are fixedly installed on the base 1. The third shaft 901 is rotatably inserted into the multiple bearing supports 11 to provide stable support for the third shaft 901. When the drive motor 10 is started and rotates forward, the drive motor 10 drives the drive gear 9 to rotate counterclockwise via the third shaft 901. The drive gear 9 drives the driven gear 8 to rotate clockwise. The driven gear 8 drives the swing arm 2 to rotate clockwise via the second shaft 801, so that the clamping mechanism and the nameplate 26 elastically clamped by the clamping mechanism are removed from the etching tank 13. The etching tank 13 contains etching solution that corrodes the nameplate 26, or the etching tank 13 is equipped with a spraying mechanism for spraying etching solution. The spraying mechanism sprays the etching solution... The etching solution is sprayed onto the nameplate 26 for etching. When the drive motor 10 is started and reversed, the drive motor 10 drives the drive gear 9 to rotate clockwise through the third shaft 901. The drive gear 9 drives the driven gear 8 to rotate counterclockwise. The driven gear 8 drives the swing arm 2 to rotate counterclockwise through the second shaft 801, so that the clamping mechanism and the nameplate 26 elastically clamped by the clamping mechanism are moved into the etching tank 13, where they are etched by the etching solution contained in the etching tank 13, or by the etching solution sprayed by the spraying mechanism set in the etching tank 13.

[0026] In this embodiment, a first shaft 501 is rotatably inserted into the end of the swing arm 2 away from the driven gear 8. A clamping mechanism is fixedly installed on the first shaft 501 and is used to elastically clamp the nameplate 26. A connecting gear 5 is fixedly sleeved on the first shaft 501, and the connecting gear 5 is coaxial with the first shaft 501. A half-gear ring 3 that meshes with the connecting gear 5 is fixedly installed on the base 1 so that when the swing arm 2 is rotated, the half-gear ring 3 drives the connecting gear 5 and the first shaft 501 to rotate. When the swing arm 2 rotates clockwise, it drives the clamping mechanism to rotate synchronously, and the clamping mechanism drives the nameplate 26 to rotate. When the swing arm 2 rotates clockwise, it drives the connecting gear 5 to rotate clockwise under the meshing action of the half gear ring 3. The connecting gear 5 drives the clamping mechanism and the nameplate 26 to rotate clockwise through the first shaft 501. Similarly, when the swing arm 2 rotates counterclockwise, it drives the connecting gear 5 to rotate counterclockwise under the meshing action of the half gear ring 3. The connecting gear 5 drives the clamping mechanism and the nameplate 26 to rotate counterclockwise through the first shaft 501.

[0027] The swing arm 2 is equipped with a baffle 7 and two oppositely arranged absorbent cotton 23s. The baffle 7 is used to block the clockwise rotating nameplate 26 so that the nameplate 26 is disengaged from the clamping mechanism during the clockwise rotation. After the nameplate 26 is disengaged from the clamping mechanism, as the clamping mechanism rotates clockwise further, the clamping mechanism pushes the nameplate 26 to pass between the two absorbent cotton 23s. The high absorbency of the absorbent cotton 23s allows the two oppositely arranged absorbent cotton 23s to simultaneously remove the etching solution remaining on the two sides of the nameplate 26.

[0028] Its working principle is as follows: First, the swing arm 2 is stopped at the position where the clamping mechanism is exposed above the etching tank 13. Then, one short side of the nameplate 26 to be etched is elastically clamped on the clamping mechanism. Next, the swing arm 2 is driven to rotate counterclockwise around the second shaft 801. During the counterclockwise rotation of the swing arm 2, the clamping mechanism holding the nameplate 26 is rotated counterclockwise due to the meshing action of the half gear ring 3 and the connecting gear 5. Under the joint rotation of the swing arm 2 and the clamping mechanism, the nameplate 26 enters the etching tank 13 and comes into contact with the etching liquid in the etching tank 13. After the etching liquid submerges the nameplate 26, the drive rotation of the swing arm 2 is stopped. At this time, the swing arm 2 is limited. In this embodiment, a limiting block (not shown in the figure) is fixedly installed on the base 1 to abut against the bottom of the swing arm 2. When the nameplate 26 enters the etching tank 13 and is submerged by the etching liquid, the swing arm 2 abuts against the limiting block to lock the position of the swing arm 2, so that the nameplate 26 is stably located in the etching liquid and is etched. After etching is complete, the swing arm 2 rotates clockwise. During this rotation, the clamping mechanism holding the nameplate 26 rotates clockwise, causing the nameplate 26 and the clamping mechanism to move out of the etching tank 13. At this point, a significant amount of etching solution remains on the side of the nameplate 26. As the nameplate 26 rotates clockwise, it moves closer to the baffle 7 until its long side abuts against the baffle 7. The point where the long side of the nameplate 26 abuts against the baffle 7 is less than one-third of the way along its length (see reference). Figure 17 Then, the clamping mechanism continues to rotate clockwise, and the clamping mechanism and the baffle 7 are misaligned. Under the rotational force of the clamping mechanism, the nameplate 26 gradually separates from the clamping mechanism. When the nameplate 26 separates from the clamping mechanism, the angle between the side of the baffle 7 near the nameplate 26 and the vertical plane is greater than 0° and less than 60°, and the position where the long side of the nameplate 26 abuts against the baffle 7 is still located less than one-third of the way along the long side (see reference). Figure 18 Then, the clamping mechanism continues to rotate clockwise so that, under the weight of the nameplate 26, the long side of the nameplate 26 that abuts against the baffle 7 is in contact with the side of the baffle 7. At this time, the angle between the side of the baffle 7 near the nameplate 26 and the vertical plane is greater than 0° and less than 70° (see reference). Figure 19 This causes the nameplate 26 to move downwards along the side of the baffle 7 under the influence of gravity. The contact point between the two absorbent cottons 23 is located directly below the nameplate 26, so that the bottom of the nameplate 26 abuts against the top of the two absorbent cottons 23. Then, the clamping mechanism abuts against the top of the nameplate 26, and as the clamping mechanism rotates further, it pushes the nameplate 26 downwards, causing it to slide between the two absorbent cottons 23 (see reference). Figure 20 The two absorbent cottons 23 absorb and remove the residual etching solution on the nameplate 26. The top edges of the two absorbent cottons 23 that are close to each other are formed with a cut edge 2302 so that the nameplate 26 can be inserted between the two absorbent cottons 23.

[0029] As can be seen, the present invention sets the clamping mechanism in the form of a rotating connection. The baffle 7 abuts against the nameplate 26, allowing the nameplate 26 to automatically detach from the clamping mechanism. At the same time, the tilt angle of the baffle 7 allows the nameplate 26 to slide downward along the side of the baffle 7 after detaching from the clamping mechanism. Ingeniously, the clamping mechanism abuts against the top of the nameplate 26 after detaching from it, enabling the clamping mechanism to push the nameplate 26 again. The rotational force of the clamping mechanism unexpectedly causes the clamping mechanism to press down on the nameplate 26, causing the nameplate 26 to slide between the two absorbent cottons 23. This achieves the effect of removing the residual etching solution on the nameplate 26. It eliminates the need for a pushing component for pushing the nameplate 26 and a power mechanism to provide power to the pushing component. Moreover, there is no pause between the operation of releasing the nameplate 26 and the operation of removing the etching solution from the nameplate 26. The two actions are seamlessly connected and closely coordinated, resulting in higher work efficiency. It is evident that the present invention can automatically release the nameplate from the clamping mechanism and remove the residual etching solution on the nameplate without requiring a separate release operation of the clamping mechanism or adding an additional power mechanism for cleaning the residual etching solution on the nameplate. This improves work efficiency while reducing the complexity and maintenance cost of the equipment, effectively addressing the shortcomings of the prior art.

[0030] In this embodiment, the clamping mechanism includes a clamp 14 fixedly mounted on a first shaft 501. A mounting base 15 is fixedly connected to the clamp 14 via a connecting rod 1401. A fixed clamping plate 16 is fixedly mounted on the mounting base 15. A rotating clamping plate 17 corresponding to the fixed clamping plate 16 is elastically rotatably mounted on the mounting base 15. The nameplate 26 is elastically clamped between the fixed clamping plate 16 and the rotating clamping plate 17. Specifically, the clamp 14 is fastened to the first shaft 501 by bolts. When the first shaft 501 rotates, it drives the clamp 14 to rotate synchronously. One end of the connecting rod 1401 is fixedly connected to the outer surface of the clamp 14, and the other end is fixedly connected to the mounting base 15. An inner groove 1501 is provided on one side of the bottom of the mounting base 15. The side of the bottom of the mounting base 15 away from the inner groove 1501 is used to abut against the corner of the nameplate 26 during the contact between the nameplate 26 and the baffle 7, so that the nameplate 26 can be disengaged from the clamping mechanism. The fixed clamping plate 16 is fixedly installed in the inner groove 1501. The fourth shaft 1702 is fixedly or rotatably installed in the inner groove 1501. The rotating clamping plate 17 is rotatably sleeved on the fourth shaft 1702. A clamping spring 18 is connected between the rotating clamping plate 17 and the inner wall of the inner groove 1501. One end of the clamping spring 18 is fixedly connected to the rotating clamping plate 17, and the other end is fixedly connected to the inner wall of the inner groove 1501. The clamping spring 18 is always in a compressed state. Under the elastic force of the clamping spring 18, the rotating clamping plate 17 and the fixed clamping plate 16 are elastically squeezed together. When the nameplate 26 is inserted between the rotating clamping plate 17 and the fixed clamping plate 16, the nameplate 26 is elastically clamped. The bottom of the rotating clamping plate 17 is provided with a chamfer 1701 on the side near the fixed clamping plate 16. The inclined setting of the chamfer 1701 makes it easier for the nameplate 26 to be inserted between the fixed clamping plate 16 and the rotating clamping plate 17. A protruding ridge 1601 is integrally formed on the side of the fixed clamping plate 16 near the rotating clamping plate 17. When the nameplate 26 is inserted between the fixed clamping plate 16 and the rotating clamping plate 17, the top of the nameplate 26 abuts against the protruding ridge 1601, and the end of the clamped side of the nameplate 26 is located near the end of the bottom surface of the mounting base 15. Figure 16 As shown, this ensures that the insertion depth of the nameplate 26 is constant each time the fixed clamping plate 16 and the rotating clamping plate 17 are inserted. When the nameplate 26 disengages from the clamping mechanism, the nameplate 26 separates from the fixed clamping plate 16 and the rotating clamping plate 17.

[0031] In this embodiment, the clamping mechanism also includes a cylinder 19 fixedly connected to the mounting base 15 via an extension rod 20. The cylinder 19 abuts against the top of the nameplate 26. Specifically, one end of the extension rod 20 is fixedly connected to the cylinder 19, and the other end is fixedly connected to the mounting base 15. During the process of the nameplate 26 disengaging from the clamping mechanism, the cylinder 19 and the nameplate 26 are misaligned. When the side of the nameplate 26 abuts against the side of the baffle 7, the cylinder 19 is positioned above the nameplate 26. As the swing arm 2 drives the cylinder 19 to continue rotating clockwise, the cylinder 19 presses down on the nameplate 26, causing it to slide between the two absorbent cottons 23, thereby removing the residual etching solution on the nameplate 26. Throughout the entire process of the cylinder 19 pressing down on the nameplate 26, the extension rod 20 and the cylinder 19 never abut against each other. The absorbent cotton 23 is typically made of a blend of polyester and viscose fibers. While polyester fibers themselves have some absorbency, in absorbent cotton they primarily provide structural support, enabling the absorbent cotton to form a three-dimensional network structure, thereby improving its overall absorbency and retention. Viscose fibers are cellulose fibers extracted from plants and possess excellent absorbency and moisture retention. In absorbent cotton, viscose fibers are responsible for absorbing water, with an absorption capacity of approximately 15 times its own weight. This gives absorbent cotton 23 excellent absorbency and structural support, while also exhibiting significant shrinkage. When the absorbent cotton 23 is compressed and contracts, the absorbed liquid is squeezed out. Of course, absorbent cotton 23 can also be supported by superabsorbent polymers, wood fibers, or other elastic and absorbent materials.

[0032] In this embodiment, a fixing block 6 is fixedly installed on the swing arm 2, and a U-shaped plate 25 is fixedly installed on the fixing block 6. A baffle 7 is fixedly connected to the fixing block 6. Two absorbent cottons 23 are located inside the U-shaped plate 25, and the baffle 7 is located above the absorbent cottons 23. The opposing surfaces of the two absorbent cottons 23 press against each other. Specifically, the absorbent cottons 23 and the baffle 7 are fixedly installed on the same side of the fixing block 6, and the absorbent cottons 23 are located below the baffle 7. The U-shaped plate 25 provides support for the absorbent cottons 23. The opposing surfaces of the two absorbent cottons 23 press against each other, so that when the nameplate 26 enters between the two absorbent cottons 23, it presses against the side of the absorbent cottons 23, so that the etching solution on the nameplate 26 is absorbed by the absorbent cottons 23.

[0033] Furthermore, a side groove 701 is provided on the side of the baffle 7 away from the fixing block 6. The side groove 701 penetrates the top and bottom of the baffle 7. The side groove 701 includes a guide groove 7011 and a limiting groove 7012 arranged sequentially from the outside to the inside of the baffle 7 and connected to each other. After the nameplate 26 is separated from the clamping mechanism, its side passes through the guide groove 7011 and enters the limiting groove 7012. Specifically, the opening of the guide groove 7011 gradually increases towards the outside of the side groove 701, so that the nameplate 26 can enter the guide groove 7011 within a larger range, with a higher fault tolerance. The two opposing surfaces of the limiting groove 7012 are arranged in parallel, and the vertical distance between the two parallel opposing surfaces of the limiting groove 7012 is slightly greater than the thickness of the nameplate 26. Specifically, the vertical distance between the two parallel opposing surfaces of the limiting groove 7012 is 0.1-1mm greater than the thickness of the nameplate 26, so that the nameplate 26 can smoothly enter the limiting groove 7012 without significant tilting or shaking. When the nameplate 26 passes through the guide groove 7011 and enters the limiting groove 7012... The side groove 701 is used to limit the nameplate 26. During the clockwise rotation of the nameplate 26 with the clamping mechanism, the long side of the nameplate 26 enters the limiting groove 7012 through the guide groove 7011. When the nameplate 26 is separated from the clamping mechanism, the nameplate 26 rotates towards the baffle 7 under the action of gravity, so that the long side of the nameplate 26 enters the limiting groove 7012 through the guide groove 7011 and is parallel to the inner wall of the limiting groove 7012. Then, under the limiting action of the limiting groove 7012, when the cylinder 19 on the clamping mechanism presses down on the nameplate 26, the nameplate 26 can move smoothly down along the side of the baffle 7 to between the two absorbent cottons 23, so as to remove the etching solution on the nameplate 26.

[0034] In this embodiment, a placement groove 101 is provided on the base 1, and an etching tank 13 for storing etching solution is placed in the placement groove 101.

[0035] Furthermore, a squeezing plate 21 is elastically slidably inserted into the fixing block 6, and an arc-shaped plate 12 is fixedly installed on the base 1. One end of the squeezing plate 21 is fixedly connected to the ends of the two absorbent cottons 23, and the other end abuts against the outer arc surface of the arc-shaped plate 12. The vertical distance from the outer arc surface of the arc-shaped plate 12 abutting the squeezing plate 21 to the second shaft 801 gradually decreases, so that the vertical distance from the end of the squeezing plate 21 to the outer arc surface of the arc-shaped plate 12 gradually increases during the clockwise rotation of the squeezing plate 21. Similarly, the vertical distance from the end of the squeezing plate 21 to the outer arc surface of the arc-shaped plate 12 gradually decreases during the counterclockwise rotation of the squeezing plate 21. The end of the absorbent cotton 23 away from the squeezing plate 21 is fixedly connected to the U-shaped plate 25, and the side of the two absorbent cottons 23 that are away from each other is squeezed and adhered to the inner wall of the U-shaped plate 25. Specifically, slide rails 2101 are fixedly installed on both the front and rear sides of the extrusion plate 21. A slide channel 602 is provided through the fixing block 6 for the extrusion plate 21 and slide rails 2101 to slide into. The slide rails 2101 prevent the extrusion plate 21 from moving in its height direction, allowing it to slide only along its length. Spring seats 2102 are also fixedly installed on both the front and rear sides of the extrusion plate 21. Receiving holes 601 are provided on the receiving holes 601, each corresponding to one of the two spring seats 2102, to accommodate… A reset spring 24 is connected between the hole 601 and the corresponding spring seat 2102. One end of the reset spring 24 is fixedly connected to the spring seat 2102, and the other end is fixedly connected to the inside of the receiving hole 601. The elastic force of the reset spring 24 enables elastic sliding between the extrusion plate 21 and the fixing block 6. An abutment block 2103 is fixedly installed on the extrusion plate 21. The abutment block 2103 abuts against the side of the fixing block 6 to keep the reset spring 24 in a compressed state and to limit the extrusion plate 21. An insertion block 2301 is fixedly installed on the end of the absorbent cotton 23 away from the fixing block 6. An insertion groove 2501 corresponding to the insertion block 2301 is opened on the inner wall of the U-shaped plate 25. The insertion block 2301 is fixedly inserted into the corresponding insertion groove 2501.

[0036] In this embodiment, when the nameplate 26 is being etched in the etching tank 13, the end of the extrusion plate 21 is elastically pressed against the outer arc surface of the arc plate 12. At this time, the compression of the reset spring 24 is at its maximum, and the two absorbent cottons 23 are compressed by the extrusion plate 21 and the U-shaped plate 25. The abutment block 2103 and the fixing block 6 are not in contact. As the swing arm 2 drives the extrusion plate 21 to rotate clockwise, the elastic force of the reset spring 24 is gradually released, pushing the extrusion plate 21 to slide away from the absorbent cotton 23. This causes the compressed absorbent cotton 23 to gradually open and lengthen. At the same time, the extrusion force between the end of the extrusion plate 21 and the outer arc surface of the arc plate 12 gradually decreases. Before the cylinder 19 abuts against the nameplate 26, the abutment block 2103 abuts against the fixing block 6. Figure 18In the state shown, the extrusion plate 21 is located on the right side of the side groove 701, and the absorbent cotton 23 covers the bottom of the side groove 701 so that when the nameplate 26 is pressed down by the cylinder 19, the nameplate 26 can be inserted between the two absorbent cottons 23 without being obstructed by the extrusion plate 21. When the extrusion plate 21 continues to rotate clockwise, the end of the extrusion plate 21 separates from the outer arc surface of the arc plate 12. Similarly, as the swing arm 2 drives the extrusion plate 21 to rotate counterclockwise, the outer arc surface of the arc plate 12 pushes the extrusion plate 21 to slide towards the absorbent cotton 23 to squeeze out the etching liquid in the absorbent cotton 23. The squeezed-out etching liquid flows into the etching tank 13 for collection and reuse.

[0037] As can be seen, by elastically sliding the extrusion plate 21 and fixing the arc plate 12 that abuts against the extrusion plate 21, the present invention can cleverly achieve the extrusion of the extrusion plate 21 on the absorbent cotton 23 during the counterclockwise rotation of the extrusion plate 21, thereby producing the technical effect of automatically squeezing out the etching liquid in the absorbent cotton 23, eliminating the need for separate cleaning of the etching liquid in the absorbent cotton 23 later, saving time and effort.

[0038] Among them, a roller 22 is rotatably installed on the end of the extrusion plate 21 near the arc plate 12. The circumferential surface of the roller 22 abuts against the outer arc surface of the arc plate 12. The abutting cooperation between the end of the extrusion plate 21 and the outer arc surface of the arc plate 12 is achieved by the abutting cooperation between the circumferential surface of the roller 22 and the outer arc surface of the arc plate 12. This can effectively reduce the friction between the extrusion plate 21 and the arc plate 12, thereby avoiding wear.

[0039] The half-gear ring 3 and the driven gear 8 are coaxial.

[0040] Second embodiment: like Figure 21-22As shown, the difference between this embodiment and the first embodiment is that the diameter of the driven gear 8 is larger than the diameter of the driving gear 9, and the bottom height of the driven gear 8 is lower than the bottom height of the driving gear 9. A movable receiving plate 27 is slidably disposed on the etching groove 13. A toothed plate 2702 that meshes with the driven gear 8 is fixedly installed on the movable receiving plate 27. An avoidance hole 2701 is opened on the movable receiving plate 27 for the arc plate 12 to pass through, so that the arc plate 12 will not obstruct the left and right sliding of the movable receiving plate 27. During the process of the clamping mechanism rotating and pressing down the nameplate 26 so that the nameplate 26 slides between the two absorbent cottons 23, the driven gear 8 drives the movable receiving plate 27 to slide, so that the movable receiving plate 27 receives the nameplate 26. Specifically, a guide plate 1301 is fixedly installed on the side of the etching tank 13. The movable receiving plate 27 is slidably inserted into the guide plate 1301. An opening for the movable receiving plate 27 to be inserted is provided on the etching tank 13. The bottom height of the movable receiving plate 27 is higher than the liquid level of the etching solution in the etching tank 13, so as not to cause the etching solution to leak. When the nameplate 26 is corroded in the etching solution, the movable receiving plate 27 is offset from the absorbent cotton 23 so that the etching solution squeezed out from the absorbent cotton 23 will not fall onto the movable receiving plate 27. When the driven gear 8 drives the rocker arm 2 to rotate clockwise, on the one hand, the driven gear 8 drives the movable receiving plate 27 to slide horizontally toward the absorbent cotton 23 through the toothed plate 2702. On the other hand, since the absorbent cotton 23 also rotates clockwise, the absorbent cotton 23 also moves closer to the absorbent cotton 23 in the horizontal direction. When the cylinder 19 presses down on the nameplate 26, or before pressing down on the nameplate 26, the movable receiving plate 27 overlaps with the nameplate 26 in the vertical direction so that when the nameplate 26 is pressed down by the cylinder 19 to the final stage, the nameplate 26 falls onto the movable receiving plate 27 and is received and collected, preventing the nameplate 26 from falling into the etching tank 13 during the pressing process by the cylinder 19. When the swing arm 2 rotates counterclockwise, the movable receiving plate 27 gradually moves away from the absorbent cotton 23 in the horizontal direction. When the absorbent cotton 23 is squeezed again by the squeezing plate 21 or in the initial stage of being squeezed by the squeezing plate 21 (when the absorbent cotton 23 is squeezed out of the etching liquid, it is in the middle and late stage of the squeezing of the absorbent cotton 23), the movable receiving plate 27 and the absorbent cotton 23 are staggered in the vertical direction, so that when the absorbent cotton 23 is squeezed out of the etching liquid, the etching liquid will not fall onto the movable receiving plate 27.

[0041] Therefore, as can be seen, during the clockwise rotation of the swing arm 2 driven by the driven gear 8, the present invention can not only release the nameplate 26 and remove the etching liquid on the nameplate 26, but also, through the meshing of the driven gear 8 and the toothed plate 2702 and the clockwise rotation of the absorbent cotton 23, make the movable receiving plate 27 overlap with the nameplate 26 in the vertical direction. This produces the technical effect that when the nameplate 26 is pressed down by the cylinder 19 to the final stage, the nameplate 26 falls onto the movable receiving plate 27 and is received and collected, preventing the nameplate 26 from falling into the etching tank 13 during the pressing process by the cylinder 19. With only one drive source required, the automation level of the equipment is greatly improved, the working efficiency of the equipment is guaranteed, and the manufacturing cost and subsequent maintenance cost of the equipment are greatly reduced.

[0042] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
