Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and in particular to a surface cleaning mechanism for an FPC circuit board processing platform. Background Technology

[0002] FPC (Flexible Printed Circuit) refers to flexible circuit boards. The production process of FPC begins with material preparation. Large sheets of flexible copper-clad laminate are precisely cut into smaller boards according to design requirements. Next, through-holes are drilled. Then, electroplating processes deposit metals such as copper, nickel, and gold on the hole walls and circuit surfaces to improve conductivity and corrosion resistance. Photolithography and etching techniques are then used to fabricate the circuitry, transferring the design pattern to the circuit board and removing excess copper to ensure the circuit width and spacing meet standards. Finally, an insulating film is applied to protect the circuitry. When applying the insulating film, the semi-finished flexible circuit board is laid flat on a workbench, the insulating film is placed on its surface, and then the two are bonded together using laminating equipment. To maintain the cleanliness of the workbench surface and prevent dust or other foreign matter from damaging the flexible circuit board, the workbench surface must be wiped clean with a cloth.

[0003] When covering the semi-finished flexible circuit board with an insulating film, the semi-finished flexible circuit board needs to be placed on a workbench for assembly. In order to improve the cleanliness of the workbench surface and prevent dust or other foreign objects from adhering to its surface and damaging the surface of the flexible circuit board, a wiping cloth is needed to wipe and clean the workbench surface. However, when cleaning the workbench surface with a hand-held wiping cloth, the pressure distribution at the contact point between the wiping cloth and the workbench surface is uneven, which can easily create cleaning dead corners and affect the cleaning effect of the workbench. Therefore, this application provides a surface cleaning mechanism for an FPC circuit board processing platform to meet the needs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a surface cleaning mechanism for an FPC circuit board processing platform to solve the problem that when a handheld wiping cloth is used to clean the surface of the workbench, the pressure distribution at the contact point between the wiping cloth and the workbench surface is uneven, which easily creates cleaning dead corners and thus affects the cleaning effect on the workbench.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A surface cleaning mechanism for an FPC circuit board processing platform includes a cylinder, the outer wall of which is attached with a wiping cloth by Velcro, a notch is provided at the bottom of the outer wall of the cylinder, an elastic support mechanism is installed in the notch, and a U-shaped handle is installed at the end of the cylinder.

[0007] The elastic support mechanism includes a rubber strip located inside the notch, and a V-shaped locking block is fixed on the opposite side of the rubber strip. A slot is provided on the inner wall of the notch corresponding to the V-shaped locking block, and the V-shaped locking block is locked in the slot. An upper plate is fixed to the top of the rubber strip and is attached to the top of the inner wall of the notch. The bottom of the rubber strip is attached to the side of the wiping cloth near the cylinder.

[0008] Preferably, a connecting post is fixed to the bottom of the upper plate, and a rubber strip is sleeved on the outer wall of the connecting post.

[0009] Preferably, the rubber strip has several square cavities inside, and an arc-shaped block is fixed to the inner wall of the square cavity. The arc-shaped block corresponds to the position of the V-shaped locking block, and the bottom of the connecting column is attached to the top of the arc-shaped block.

[0010] Preferably, the bottom of the connecting column is provided with a protrusion, the length of the protrusion is greater than the diameter of the connecting column, and the bottom of the protrusion fits against the top of the arc-shaped block.

[0011] Preferably, the bottom of the rubber strip is provided with a curved surface, which is in contact with the side of the wiping cloth near the cylinder.

[0012] Preferably, both ends of the rubber strip are fixed with lugs, and a stop is fixed to the bottom of the outer wall of the cylinder. The side of the stop fits against the end of the rubber strip, and the lugs are engaged with the inner wall of the stop.

[0013] Preferably, the top of the lifting ear is provided with a protrusion.

[0014] Preferably, the protrusion has a slope on the side near the stop.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above solution, the wiping cloth is attached to the cylinder with Velcro by setting the rubber strip, so that the wiping cloth contacts the workbench surface at the position corresponding to the rubber strip. The rubber strip provides elastic support for the wiping cloth, making the pressure distribution at the contact position between the wiping cloth and the workbench more uniform, effectively preventing the formation of cleaning dead corners, thereby improving the cleaning effect on the workbench.

[0017] By using a curved surface design, the contact point between the wiping cloth and the rubber strip is curved. This curved surface design allows the entire cleaning mechanism to maintain elastic support for the wiping cloth even when it is tilted, making it easy to use.

[0018] By using the connecting column and the arc-shaped block, the worktable exerts a reaction force on the wiping cloth during the wiping process. When this reaction force is transmitted to the rubber strip, it causes the rubber strip to move upward and deform. The rubber strip then causes the arc-shaped block to move upward synchronously. At this time, the protrusion at the bottom of the connecting column will squeeze the arc-shaped block, causing the arc-shaped block to change from an arc shape to a horizontal state. This causes the end of the arc-shaped block to squeeze the V-shaped locking block, making the V-shaped locking block fit tightly against the inner wall of the slot, thereby improving the installation stability and reliability of the rubber strip under pressure.

[0019] With the addition of a handle and a raised section, when removing the rubber strip, pinch the raised section of the handle to increase the contact area between the handle and your fingers, making it easier to pull the handle and remove the rubber strip from the notch, thus facilitating the replacement of the rubber strip.

According to specific needs, those skilled in the art can adjust or modify these devices and environments, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0030] The surface cleaning mechanism of an FPC circuit board processing platform provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should also be noted that, in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can also use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0031] like Figures 1-7 As shown, an embodiment of this utility model provides a surface cleaning mechanism for an FPC circuit board processing platform, including a cylinder 1. A wiping cloth 3 is attached to the outer wall of the cylinder 1 by Velcro. A notch 2 is provided at the bottom of the outer wall of the cylinder 1. An elastic support mechanism 4 is installed in the notch 2. A U-shaped handle is installed at the end of the cylinder 1.

[0032] The elastic support mechanism 4 includes a rubber strip 5 located inside the notch 2. V-shaped locking blocks 8 are fixed to the opposite side of the rubber strip 5. The number of V-shaped locking blocks 8 can be increased or decreased according to the length of the rubber strip 5. A slot 9 is provided on the inner wall of the notch 2 corresponding to the V-shaped locking blocks 8, and the V-shaped locking blocks 8 are locked in the slot 9. An upper plate 11 is fixed to the top of the rubber strip 5, and the upper plate 11 is attached to the top of the inner wall of the notch 2. The bottom of the rubber strip 5 is attached to the side of the wiping cloth 3 closest to the cylinder 1. The cylinder 1 serves as the main support structure of the cleaning mechanism, providing an attachment carrier for the wiping cloth 3. (The last sentence appears to be incomplete and possibly refers to a U-shaped support mechanism.) The handle allows operators to easily grip and move the cleaning mechanism on the workbench. The wiping cloth 3 is attached to the outer wall of the cylinder 1 via Velcro, making it easy to replace and fix. At the same time, the wiping cloth 3 directly contacts the workbench surface for cleaning. The notch 2 provides installation space for the elastic support mechanism 4. The rubber strip 5 uses its own elasticity to provide support for the wiping cloth 3, ensuring that the pressure is evenly distributed when the wiping cloth 3 contacts the workbench, effectively preventing the formation of cleaning dead corners and improving the cleaning effect. The V-shaped locking block 8 cooperates with the slot 9 to achieve stable installation of the rubber strip 5 within the notch 2, preventing the rubber strip 5 from shifting randomly during the cleaning process.

[0033] like Figure 3As shown, in this embodiment, a connecting post 12 is fixed to the bottom of the upper plate 11, and a rubber strip 5 is sleeved on the outer wall of the connecting post 12. The connecting post 12 is used to increase the contact area between the upper plate 11 and the rubber strip 5, thereby improving the tightness of the connection between the upper plate 11 and the rubber strip 5.

[0034] like Figures 3-6 As shown, in this embodiment, the rubber strip 5 has several square cavities 7 inside. An arc-shaped block 10 is fixed to the inner wall of the square cavity 7. The arc-shaped block 10 corresponds to the position of the V-shaped locking block 8. The bottom of the connecting column 12 is in contact with the top of the arc-shaped block 10. When the rubber strip 5 moves upward and deforms, the bottom of the connecting column 12 squeezes the arc-shaped block 10. The arc-shaped block 10 is deformed by force, which in turn squeezes the V-shaped locking block 8, making the V-shaped locking block 8 fit more tightly with the inner wall of the slot 9. This improves the installation stability and reliability of the rubber strip 5 after being pressed, and ensures that the rubber strip 5 will not loosen due to force during the cleaning process.

[0035] like Figure 4 and Figure 6 As shown, in this embodiment, the bottom of the connecting post 12 is provided with a protrusion 13. The length of the protrusion 13 is greater than the diameter of the connecting post 12, and the bottom of the protrusion 16 is in contact with the top of the arc block 10. The protrusion 13 increases the contact area and squeezing force between the connecting post 12 and the top of the arc block 10. When the rubber strip 5 moves upward and deforms due to the reaction force of the worktable on the wiping cloth 3, the protrusion 13 can squeeze the arc block 10 more effectively, causing the arc block 10 to change from an arc shape to a horizontal state more quickly and stably, thereby squeezing the V-shaped card block 8 in time, so that the V-shaped card block 8 is tightly attached to the inner wall of the card groove 9.

[0036] like Figure 2 As shown, in this embodiment, the bottom of the rubber strip 5 is provided with a curved surface 6. The curved surface 6 is attached to the side of the wiping cloth 3 near the cylinder 1. The curved surface 6 is designed at the bottom of the rubber strip 5 and is attached to the wiping cloth 3. When the cleaning mechanism is in an inclined state during operation, the curved surface 6 can ensure that the rubber strip 5 continuously provides elastic support to the wiping cloth 3, and avoid the wiping cloth 3 from having poor contact with the workbench due to the tilt of the cleaning mechanism, thus affecting the cleaning effect.

[0037] like Figure 2 , Figures 5-7As shown, in this embodiment, both ends of the rubber strip 5 are fixed with lugs 15, and the bottom of the outer wall of the cylinder 1 is fixed with a stop seat 14. The side of the stop seat 14 is in contact with the end of the rubber strip 5, and the lugs 15 are locked in the inner wall of the stop seat 14. The lugs 15 are fixed at both ends of the rubber strip 5, which makes it convenient for the operator to pull when replacing the rubber strip 5. The stop seat 14 is fixed at the bottom of the outer wall of the cylinder 1, and its side is in contact with the end of the rubber strip 5, which plays a limiting role for the rubber strip 5 and prevents the rubber strip 5 from moving axially during operation. At the same time, the lugs 15 are locked in the inner wall of the stop seat 14, which further stabilizes the installation position of the rubber strip 5. When it is necessary to replace the rubber strip 5, the rubber strip 5 can be pulled out from the notch 2 by pulling the lugs 15, so as to realize the convenient replacement of the rubber strip 5.

[0038] like Figure 7 As shown, in this embodiment, a protrusion 16 is provided on the top of the lifting ear 15. The protrusion 16 is provided on the top of the lifting ear 15, which increases the contact area between the lifting ear 15 and the operator's fingers, so that when the operator pinches the lifting ear 15 and pulls the rubber strip 5, he can apply force more stably and is less likely to slip.

[0039] like Figure 7 As shown, in this embodiment, a slope 17 is provided on the side of the protrusion 16 near the stop 14. The slope 17 is provided on the side of the protrusion 16 near the stop 14, which avoids sharp edges on the side of the protrusion 16 and improves the comfort of operation. At the same time, the design of the slope 17 increases the contact area between the protrusion 16 and the lifting ear 15, prevents cracking at the edge of the connection, and improves the service life of the lifting ear 15.

[0040] Working principle: The cleaning mechanism mainly consists of a cylinder 1, a wiping cloth 3 attached to the outer wall of the cylinder 1 by Velcro, and an elastic support mechanism 4 installed in the notch 2 at the bottom of the outer wall of the cylinder 1. The rubber strip 5 in the elastic support mechanism 4 is located in the notch 2, and the V-shaped locking block 8 on the opposite side is locked in the slot 9 on the inner wall of the notch 2 to fix the rubber strip 5. When the operator holds the U-shaped handle and pushes the cylinder 1 to move on the workbench for cleaning, the rubber strip 5 provides elastic support for the wiping cloth 3, making the pressure distribution at the contact position between the wiping cloth 3 and the workbench more uniform, effectively preventing the generation of cleaning dead corners, thereby improving the cleaning effect on the workbench.

[0041] Meanwhile, the curved surface 6 at the bottom of the rubber strip 5 fits into the wiping cloth 3. Even if the entire cleaning mechanism is tilted, the design of the curved surface 6 can still ensure that the rubber strip 5 continuously provides elastic support to the wiping cloth 3, ensuring that the cleaning work is not affected by the tilt angle of the device and is easy to use.

[0042] During the wiping process, the reaction force of the workbench on the wiping cloth 3 is transmitted to the rubber strip 5 through the wiping cloth 3, causing the rubber strip 5 to move upward and deform. When the rubber strip 5 moves upward, it simultaneously causes the arc-shaped block 10 inside its internal square cavity 7 to move upward. At this time, the protrusion 13 at the bottom of the connecting column 12 will squeeze the arc-shaped block 10. Under the pressure of the protrusion 13, the arc-shaped block 10 changes from its original arc shape to a horizontal state, thereby pressing the arc-shaped block 10 against the position of the V-shaped locking block 8, making the V-shaped locking block 8 fit tightly against the inner wall of the slot 9. This improves the installation stability and reliability of the rubber strip 5 after being pressed, ensuring that even when subjected to a large reaction force or when the wiping cloth 3 pulls on the rubber strip 5 during the cleaning process, the rubber strip 5 will not loosen or shift, ensuring the continuous and stable progress of the cleaning work.

[0043] After prolonged use, the elasticity of the rubber strip 5 will gradually decrease, at which point the rubber strip 5 needs to be replaced. When replacing it, the operator pinches the protrusion 16 at the top of the lifting ear 15. The protrusion 16 increases the contact area between the lifting ear 15 and the fingers, allowing the operator to pinch the lifting ear 15 more stably. At the same time, the inclined surface 17 on the side of the protrusion 16 near the stop seat 14 prevents the protrusion 16 from having a sharp edge on the side near the stop seat 14, thereby improving the comfort when pinching the protrusion 16. The operator pulls the lifting ear 15 to pull the rubber strip 5 downwards. The inner wall of the slot 9 squeezes the V-shaped locking block 8, causing the V-shaped locking block 8 and the rubber strip 5 to deform simultaneously at the corresponding position of the V-shaped locking block 8, so that the V-shaped locking block 8 separates from the slot 9. After separation, the rubber strip 5 can be pulled out from the notch 2, completing the disassembly of the rubber strip 5.

[0044] Then, align the upper plate 11 on the new rubber strip 5 with the notch 2, press the rubber strip 5 so that it is inserted into the notch 2, and the inner wall of the notch 2 squeezes the V-shaped locking block 8 to deform the V-shaped locking block 8. When the upper plate 11 is attached to the top of the inner wall of the notch 2, the V-shaped locking block 8 is locked in the slot 9 under its own elasticity and the elasticity of the rubber strip 5, thus completing the installation of the rubber strip 5. Then, wrap the wiping cloth 3 around the cylinder 1 and stick it with Velcro, and it can be used again.

[0045] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art can fully understand this utility model even without these detailed descriptions.

[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
