Description
Technical Field
[0001] This utility model relates to the field of etching product demolding technology, specifically a demolding device for etching products. Background Technology
[0002] Stripping is a critical step in the production of etched products after etching. It is necessary to remove the protective ink layer that protects the pattern to obtain the desired structure, which is usually achieved by stripping solution.
[0003] Existing demolding devices are mostly single-sided spraying or fixed immersion structures, which easily lead to uneven contact between the material and the demolding liquid, resulting in ink residue. In addition, manual intervention is required for flipping and transportation, which is not only inefficient, but also prone to scratching the product due to operational errors, thereby affecting the accuracy of subsequent processing and making it difficult to adapt to the needs of mass production.
[0004] Therefore, there is an urgent need for a stripping device for etched products to solve the above problems. Utility Model Content
[0005] Based on the above, the purpose of this utility model is to provide a demolding device for etched products, so as to solve the problem of demolding and flipping etched products.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A stripping device for etched products includes: a spray module, a feeding assembly, and a flipping assembly; A spray module includes at least one spray head for spraying a stripping liquid onto the material to remove the residual ink protective layer after etching. A feeding assembly, located below the spray head, is used to carry and transport the material to be demolded; A flipping component, located at the feeding end of the feeding component, is used to flip the material to achieve uniform demolding on both sides of the material, thus avoiding ink residue from affecting subsequent processing or product quality.
[0007] As a preferred embodiment of a stripping device for etched products, the feeding assembly includes a frame and a plurality of rollers arranged along the feeding direction. The rollers are rotatably connected to the frame and are used to drive the material to move along the feeding direction.
[0008] As a preferred embodiment of a stripping device for etched products, the flipping assembly includes a flipping block and a driving component. The flipping block is rotatably connected to the feeding end of the feeding assembly, and the driving component is used to drive the flipping block to flip around a rotation axis to achieve a 180° flipping of the material.
[0009] As a preferred embodiment of a stripping device for etched products, one end of the flipping block is connected to the driving component, and the other end of the flipping block is set as an inlet end, which faces the feeding direction of the feeding component and is used to receive the material transported by the feeding component.
[0010] A preferred embodiment of a stripping device for etched products further includes guide rods disposed on both sides of the feeding assembly for guiding and limiting the material during transportation.
[0011] A preferred embodiment of a stripping device for etched products further includes a sensor that irradiates along the inlet end of the flipping block to detect whether material has entered the flipping block, thereby triggering the action of the flipping assembly.
[0012] A preferred embodiment of a stripping device for etched products further includes a collection component disposed below the feeding component for recovering the spray liquid and realizing resource recycling.
[0013] As a preferred embodiment of a stripping device for etched products, the collecting assembly includes a collecting box and a baffle. The baffle is laid at the bottom of the feeding assembly in the feeding direction, and the collecting box is installed at the bottom of the baffle. The bottom of the baffle is provided with a through hole for communicating with the collecting box.
[0014] As a preferred embodiment of a stripping device for etched products, the top surface of the baffle is provided with a stepped guide plate. The stepping direction of the stepped guide plate is towards the feeding end of the feeding assembly, and both ends of the stepped guide plate extend along the feeding direction of the feeding assembly. This is used to guide the spray liquid in multiple stages, avoid splashing of the spray liquid, and guide it to flow into the through hole.
[0015] The beneficial effects of this utility model are as follows: by setting up a spray module, a feeding component, and a flipping component, the feeding component can stably carry and transport materials, allowing the materials to continuously pass under the spray module, and the spray head can spray the demolding liquid in a targeted manner; at the same time, the flipping component flips the materials at the feeding end, so that both sides of the materials can fully contact the demolding liquid, avoiding the problem of uneven demolding caused by single-sided spraying of materials in traditional devices, thereby achieving uniform demolding of materials on both sides, effectively removing residual ink, and thus ensuring the accuracy of subsequent processing and product quality. Moreover, no manual flipping is required, reducing human intervention and improving the efficiency of demolding operations. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0019] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0020] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0021] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0022] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.
[0023] In one embodiment of this utility model, such as Figure 1-5 As shown, a stripping device for etched products is provided, comprising: a spray module 1, a feeding assembly 2, and a flipping assembly 3. The spray module 1 includes at least one spray head 101 for spraying stripping liquid onto the material to remove residual ink protective layer after etching. The feeding assembly 2, disposed below the spray head 101, is used to carry and transport the material to be stripped. The flipping assembly 3, disposed at the feeding end of the feeding assembly 2, is used to flip the material to achieve uniform stripping from both sides, preventing ink residue from affecting subsequent processing or product quality.
[0024] The etching product stripping device provided by this utility model includes a spray module 1, a feeding component 2, and a flipping component 3. The feeding component 2 can stably carry and transport the material, allowing the material to continuously pass under the spray module 1, where the spray head 101 can spray stripping liquid in a targeted manner. At the same time, the flipping component 3 flips the material at the feeding end, ensuring that both sides of the material can fully contact the stripping liquid. This avoids the problem of uneven stripping caused by spraying only one side of the material in traditional devices, thereby achieving uniform stripping of the material on both sides, effectively removing residual ink, and ensuring the accuracy of subsequent processing and product quality. Moreover, it eliminates the need for manual flipping, reducing human intervention and improving the efficiency of the stripping operation.
[0025] Specifically, the feeding assembly 2 includes a frame 201 and several rollers 202 arranged along the feeding direction. The rollers 202 are rotatably connected to the frame 201 and are used to move the material along the feeding direction. In continuous demolding operations of etched products (such as circuit boards and metal sheets), the material can be placed stably on the rollers 202, and continuous conveying is achieved through the synchronous rotation of the rollers 202, eliminating the need for manual handling or positioning.
[0026] Preferably, the flipping component 3 includes a flipping block 301 and a driving member 302. The flipping block 301 is rotatably connected to the feeding end of the feeding component 2, and the driving member 302 is used to drive the flipping block 301 to flip around the rotation axis to achieve 180° flipping of the material.
[0027] For etched products requiring double-sided demolding (such as double-sided copper-clad laminates and metal nameplates), after the material is conveyed to the flipping block 301 by the feeding component 2, the driving component 302 (such as a servo motor) drives the flipping block 301 to precisely complete a 180° flip, ensuring that the side without demolding faces the subsequent spraying area. Compared to manual flipping, mechanical flipping has high angular accuracy, avoiding incomplete demolding in certain areas due to flipping angle deviations, and is suitable for batch continuous production scenarios.
[0028] Furthermore, one end of the tilting block 301 is connected to the drive component 302, and the other end of the tilting block 301 is set as the inlet end 303, which faces the feeding direction of the feeding component 2 and is used to receive the material transported by the feeding component 2. The inlet end 303 can stably limit the workpiece within the tilting block 301 when it is tilted, avoiding displacement or falling due to centrifugal force; at the same time, the inlet end 303 can be provided with a guide structure (such as an arc transition edge) to form a smooth transition with the conveying surface of the feeding component 2, ensuring that the workpiece will not shake due to the contact gap when the tilting action is started after entering the tilting block 301.
[0029] The stripping device for the etched product also includes a sensor 5, which is irradiated along the inlet end 303 of the flipping block 301 to detect whether the material has entered the flipping block 301, thereby triggering the action of the flipping assembly 3.
[0030] When producing materials of various specifications (such as etched circuit boards of different sizes), sensor 5 (such as an infrared sensor) can monitor in real time whether the material has completely entered the flipping block 301. Instead of the traditional timed triggering method, the flipping is only started when the material is in place, avoiding the problems of empty flipping or flipping before the material has fully entered due to fluctuations in the material conveying speed; at the same time, it can adapt to materials of different lengths, improve the compatibility of the device with multi-specification products, and reduce the parameter adjustment time during production changeover.
[0031] The stripping device for the etched product also includes guide rods 6, which are located on both sides of the feeding assembly 2 and are used to limit and guide the material during transportation.
[0032] When the etched product is conveyed by the roller 202, the guide rods 6 on both sides form a guide channel that matches the edge of the material. This can effectively correct the lateral displacement of the material caused by the deviation of the roller 202's rotation speed or the offset of its own center of gravity, ensuring that the material is always conveyed in the center along the feeding direction and avoiding deformation caused by the collision between the edge and the equipment frame.
[0033] The stripping device for the etched product also includes a collection component 4, which is located below the feeding component 2 and is used to recover the spray liquid, thereby realizing the recycling of resources.
[0034] In a continuous etching product stripping production line, the stripping solution (containing acidic or alkaline solvents) continuously sprayed by the spray module 1 drips in large quantities. The collection component 4 can centrally recover these waste liquids, avoiding chemical pollution caused by direct discharge of the stripping solution and complying with environmental regulations.
[0035] Furthermore, the collection component 4 includes a collection box 401 and a baffle 402. The baffle 402 is laid at the bottom of the feeding component 2 in the feeding direction, and the collection box 401 is installed at the bottom of the baffle 402. The bottom of the baffle 402 is provided with a through hole 403 for communicating with the collection box 401. In the demolding operation with high spray pressure, the spray liquid is prone to splashing everywhere due to impact on the material surface. The baffle 402 can form a closed lower interception space, effectively preventing the spray liquid from splashing to the outside of the equipment, protecting the workshop environment and the safety of the operators. The communicating structure between the through hole 403 and the collection box 401 allows the waste liquid collected on the baffle 402 to flow into the collection box 401 in a directed manner.
[0036] Furthermore, the top surface of the baffle 402 is provided with a stepped guide plate 404. The stepping direction of the stepped guide plate 404 is towards the feeding end of the feeding assembly 2, and both ends of the stepped guide plate 404 extend along the feeding direction of the feeding assembly 2. This is used to guide the spray liquid in multiple stages, avoid splashing of the spray liquid, and guide it to flow to the through hole 403.
[0037] When the sprayed liquid splashes, the stepped guide plate 404 can specifically guide the flow of waste liquid. The rising direction is towards the feeding end, which can guide the waste liquid to flow naturally along the stepped slope to the through hole 403, reducing liquid accumulation and improving recycling efficiency.
[0038] The demolding process in this embodiment is as follows: First, place the etched product to be de-coated (such as circuit board or metal sheet) on the roller 202 of the feeding assembly 2. After starting the equipment, the roller 202 rotates synchronously, driving the material to be conveyed downwards along the feeding direction to the spray module 1.
[0039] When the material enters the spraying area, the spray head 101 of the spraying module 1 sprays stripping liquid onto the upper surface of the material to remove the residual ink protective layer after etching. At the same time, some of the stripping liquid drips from the surface of the material or flows from the gap between the rollers 202 to the collection component 4 below. The baffle 402 intercepts the splashed stripping liquid, and the stepped guide plate 404 guides the waste liquid through the through hole 403 into the collection box 401 through the multi-level slope, so as to realize the recovery of stripping liquid.
[0040] After the material completes the demolding of the upper surface, it continues to be conveyed by the roller 202 to the inlet end 303 of the flipping block 301 of the flipping component 3. At this time, the sensor 5 shines along the inlet end 303 and detects that the material has completely entered the flipping block 301. Then, it triggers the drive component 302 to move. The drive component 302 drives the flipping block 301 to accurately complete a 180° flip around the rotation axis, so that the lower surface of the material that has not been demolded faces upward.
[0041] After the flipping is completed, the roller 202 continues to drive the material to pass under the spray module 1 again, and the spray head 101 sprays the demolding liquid onto the lower surface of the material to complete the double-sided demolding.
[0042] Finally, the demolded material is conveyed out of the equipment by roller 202. The demolding liquid recovered in the collection box 401 can be recycled to the spray module 1 after subsequent filtration and concentration adjustment. The whole process does not require manual intervention, realizing automated and continuous double-sided demolding of etched products.
[0043] In this embodiment, during use and installation, a protective cover can be installed around the spray module 1, the feeding component 2, and the flipping component 3.
[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
