Description

Technical Field

[0001] The utility model relates to the technical fields of bionic engineering and interface control, and in particular to an installation structure of a bionic adhesive pad. Background Art

[0002] Bionic adhesive pads are widely used in the semiconductor industry to repeatedly fix and transport smooth and fragile material surfaces (glass, display screens, wafers, etc.) in high vacuum and high temperature environments, solving technical problems such as mechanical clamping easily scratching, chemical adhesive easily leaving adhesive residue, and vacuum suction cups being unusable.

[0003] Under normal temperature and usage conditions, the double-sided tape can quickly and firmly fix the bionic adhesive pad to the object with its stickiness. The operation process is simple and does not require complex tools or professional skills.

[0004] For the existing installation structure, in the traditional bionic adhesive pad installation structure, due to the strong viscosity of the double-sided tape, the residual colloid is often firmly attached to the surface of the positioning block, and it is difficult to completely remove it using conventional cleaning tools and methods. Over time, the accumulation of residual colloid will cause the surface of the positioning block to be uneven, affecting the tightness of the bionic adhesive pad when it is re-attached. In addition, the traditional debonding method often lacks consideration of the internal structure of the bionic adhesive pad and the characteristics of the adhered material. The debonding process can easily cause structural damage to the adhesive layer on the surface of the bionic adhesive pad, resulting in a significant decrease in its adhesion performance. Therefore, a bionic adhesive pad installation structure is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides an installation structure of a bionic adhesive pad, which aims to improve the problem in the prior art that after the bionic adhesive pad is removed from the positioning block, the residual colloid in the double-sided adhesive layer is difficult to clean and the bionic adhesive pad and the adherend are easily damaged during the debonding operation.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A bionic adhesive pad mounting structure includes a mounting base, a positioning block and a debonding mechanism provided on the mounting base, the positioning block being connected to the bionic adhesive pad via a double-sided adhesive layer, a scraping mechanism provided on the positioning block, and a fixing component provided on the scraping mechanism;

[0009] As a further description of the above technical solution:

[0010] The positioning assembly includes a latch, and pin holes are provided on the mounting block and the rotating shaft, and the latch is arranged in the pin hole.

[0011] As a further description of the above technical solution:

[0012] The fixing assembly includes a shaft sleeve, a fixing screw is provided on the connecting block, the shaft sleeve is provided in the middle of the fixing screw, and both ends of the fixing screw are respectively threadedly connected with a fixing nut and a fixing nut.

[0013] As a further description of the above technical solution:

[0014] The internal structure of the bionic adhesive pad comprises a surface adhesive layer, a middle buffer layer, and a bottom support layer from the outside to the inside.

[0015] As a further description of the above technical solution:

[0016] The surface adhesion layer includes a microstructure layer, an adhesion material layer is provided on the outward side of the microstructure layer, and the material of the microstructure layer is polydimethylsiloxane.

[0019] As a further description of the above technical solution:

[0020] The film-unwinding mechanism includes an air pump, which is arranged on a mounting base. The output end of the air pump is connected to a fine nozzle through a pipeline. A film-unwinding frame is arranged on the outside of the fine nozzle, and the fine nozzle is fixed to the mounting base through the film-unwinding frame.

[0021] As a further description of the above technical solution:

[0022] The double-sided adhesive layer is made of polyimide, and ventilation holes are provided in the middle of the double-sided adhesive layer, the positioning block and the bionic adhesive pad.

[0023] The utility model has the following beneficial effects:

[0024] The cleaning block is then moved back into position and the cleaning rod is moved back into position to remove the dirt, thereby cleaning the block and removing the dirt.

[0025] In the utility model, the air generated by the air pump is pressurized and transported through a pipeline to a fine nozzle fixed on the mounting base by a debonding frame, and then the fine nozzle sprays high-pressure gas at the vent between the bionic adhesive pad and the adhered material. When the high-pressure airflow impacts, the elastic material layer will deform to a certain extent. On the one hand, this deformation can buffer the impact of the airflow on the underlying support layer and the mounting base, and protect the entire mounting structure; on the other hand, the reaction force generated by its deformation will be transmitted to the surface adhesion layer, and work together with the impact force of the airflow to promote the separation of the adhesion interface between the adhesive material and the adherend, and can achieve debonding in a relatively gentle and precise manner, effectively avoiding damage to both, and improving the integrity and reusability of the product.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Reference Figure 1-Figure 3 The present invention provides an embodiment of a bionic adhesive pad installation structure, comprising a mounting base 1, a positioning block 2 provided on the mounting base 1, the positioning block 2 being connected to a bionic adhesive pad 4 via a double-sided adhesive layer 3, the double-sided adhesive layer 3 being made of polyimide, and a vent 7 being provided in the middle of the double-sided adhesive layer 3, the positioning block 2, and the bionic adhesive pad 4;

[0036] The mounting base 1 is the basic bearing component of the entire mounting structure. The main function of the positioning block 2 is to provide an accurate positioning reference for the installation of the bionic adhesive pad 4. The double-sided adhesive layer 3 tightly fits the positioning block 2 and the bionic adhesive pad 4 together. In actual application, this connection method must not only ensure the stability of the connection between the two under normal use conditions, so as to ensure that the bionic adhesive pad 4 can be stably attached to the positioning block 2 and play its adhesive function, but also take into account some special circumstances, such as when the bionic adhesive pad 4 needs to be replaced or repaired. The adhesion can be relatively easily destroyed under proper operation, so that the bionic adhesive pad 4 can be smoothly removed from the positioning block 2 without causing unnecessary damage to the positioning block 2 and the bionic adhesive pad 4. Polyimide has the advantages of excellent high temperature resistance, chemical corrosion resistance and good mechanical properties. It can still maintain stable adhesion performance under relatively harsh environmental conditions, providing reliable protection for the connection between the bionic adhesive pad 4 and the positioning block 2. The vent 7 provides a unique operating method when it is necessary to remove the material adhered to the bionic adhesive pad 4.

[0037] Reference Figure 1-Figure 3 and Figure 5-Figure 6 , a scraping mechanism 5 is provided on the positioning block 2, and the scraping mechanism 5 includes a slider 502, a scraping groove 501 is opened on the positioning block 2, the slider 502 is slidably connected to the inside of the scraping groove 501, a mounting block 503 is provided on the slider 502, a rotating shaft 505 is provided in the mounting block 503, a connecting block 506 is provided on the rotating shaft 505, and the connecting block 506 is connected to the scraper 504 through the fixing component 6, and a pull ring 507 and a positioning component are provided on the mounting block 503;

[0038] The scraping groove 501 provides a stable guide path for the overall movement of the scraping mechanism 5, so that the slider 502 can slide smoothly along the preset direction in the scraping groove 501, thereby ensuring the accuracy of the movement trajectory of other scraping components connected thereto (such as the scraper 504) when performing a scraping operation on the positioning block 2. The rotating shaft 505 provides a central axis of rotation for the connecting block 506, so that the scraper 504 can be stored when not in use. The presence of the pull ring 507 provides the operator with a convenient operating point.

[0039] The positioning assembly includes a latch 509, and pin holes 508 are provided on the mounting block 503 and the rotating shaft 505. The latch 509 is set in the pin hole 508. When it is necessary to fix the angle of the scraper 504 or the position of the mounting block 503, it is only necessary to insert the latch 509 into the corresponding pin hole 508. The tight fit between the latch 509 and the pin hole 508 can effectively limit the relative movement of the components, thereby achieving the purpose of positioning.

[0040] Reference Figure 1-Figure 3 The scraping mechanism 5 is provided with a fixing component 6, which includes a sleeve 601. A fixing screw 602 is provided on the connecting block 506. The sleeve 601 is provided in the middle of the fixing screw 602. The two ends of the fixing screw 602 are respectively threadedly connected with a fixing nut 603 and a fixing nut 604. The sleeve 601 and the fixing screw 602 cooperate with each other. On the one hand, they can provide a stable support point and rotation axis for adjusting the scraper 504. By tightening the fixing nut 604, the position and angle of the scraper 504 can be accurately adjusted according to actual needs. In addition, during the scraping operation, a stable fastening force can be continuously applied to ensure that the scraper 504 will not loosen or deviate when subjected to scraping resistance.

[0041] Reference Figure 4The internal structure of the bionic adhesive pad 4 is composed of a surface adhesive layer 401, an intermediate buffer layer 402, and a bottom support layer 403 from the outside to the inside. The surface adhesive layer 401, as the first layer interacting with the outside world, shoulders the important task of realizing efficient adhesion. It needs to establish a stable connection with objects of various materials and surface characteristics. The intermediate buffer layer 402 is like a buffer shield. Its main responsibility is to effectively absorb and disperse these forces when the bionic adhesive pad 4 is subjected to external impact or pressure, and prevent the microstructure of the surface adhesive layer 401 from being destroyed, thereby ensuring the adhesion performance and service life of the entire bionic adhesive pad 4. The bottom support layer 403, as the foundation of the entire structure, provides a stable and solid basic support for the surface adhesive layer 401 and the intermediate buffer layer 402 above.

[0042] The surface adhesion layer 401 includes a microstructure layer 4011, and an adhesion material layer 4012 is provided on the outward side of the microstructure layer 4011. The material of the microstructure layer 4011 is polydimethylsiloxane. The microstructure layer 4011 is the core component of achieving the unique adhesion performance of the biomimetic adhesion pad 4. By mimicking the microstructure of biological adhesion organs, such as the bristle structure on the paw of a gecko, the effective contact area with the surface of the adhered object is significantly increased. The polydimethylsiloxane material selected for the microstructure layer 4011 has many excellent properties and good flexibility. This allows the microstructure layer 4011 to better conform to the shape and texture of the surface of the adhered object when in contact with the surface, thereby improving the stability of adhesion. The presence of the adhesion material layer 4012 further enhances the adhesion effect of the surface adhesion layer 401.

[0043] The middle buffer layer 402 is divided into an elastic material layer 4021 and a stress dispersion structure layer 4022 from the outside to the inside. The elastic material layer 4021 is made of polyurethane foam, and the stress dispersion structure layer 4022 is honeycomb-shaped. The elastic material layer 4021 is made of polyurethane foam because polyurethane foam has extremely excellent elastic recovery ability and excellent energy absorption characteristics. When the bionic adhesion pad 4 encounters external force impact or pressure, the elastic material layer 4021 can deform quickly and convert these external forces into its own elastic potential energy for absorption and storage, thereby effectively reducing the direct impact of external forces on the surface adhesion layer 401 and the underlying support layer 403. The honeycomb structure of the stress dispersion structure layer 4022 can evenly disperse stress in all directions, avoiding excessive concentration of stress in local areas, thereby preventing the elastic material layer 4021 from deformation or damage due to excessive local pressure, greatly improving the overall buffering effect and stability of the middle buffer layer 402.

[0044] Reference Figure 1-Figure 2, a film-unraveling mechanism 8 is provided on the mounting base 1, and the film-unraveling mechanism 8 includes an air pump 801, which is provided on the mounting base 1, and an output end of the air pump 801 is connected to a fine nozzle 802 through a pipeline, and a film-unraveling frame 803 is provided on the outside of the fine nozzle 802, and the fine nozzle 802 is fixed on the mounting base 1 through the film-unraveling frame 803. The air pump 801 serves as the power source of the entire film-unraveling mechanism 8, and the main function of the film-unraveling frame 803 is to provide a stable and reliable fixed support for the fine nozzle 802, which firmly fixes the fine nozzle 802 The fine nozzle 802 is fixed on the mounting base 1 to ensure that it can maintain a precise position and a stable posture during the debonding operation. The fine nozzle 802 ejects gas in a specific direction and angle to act on the part that needs to be debonded, such as the connection area between the bionic adhesive pad 4 and the adhered object. The impact force of the high-pressure gas destroys the adhesion between the two, thereby achieving an efficient, convenient and relatively gentle debonding operation, avoiding damage to the bionic adhesive pad 4 or the adhered object that may be caused by traditional hard peeling methods.

[0045] Working principle: The bionic adhesive pad 4 is adhered to the positioning block 2 through the double-sided adhesive layer 3, and the position of the bionic adhesive pad 4 is adjusted by installing the base 1. When it is necessary to fix an object, the bionic adhesive pad 4 is composed of three layers: a surface adhesive layer 401, an intermediate buffer layer 402, and a bottom support layer 403. The microstructure layer 4011 in the surface adhesive layer 401 simulates the microstructure of biological adhesion organs, and the adhesive material layer 4012 enhances the adhesion effect, so that the bionic adhesive pad 4 can fix fragile materials. The intermediate buffer layer 402 enhances the stress dispersion ability of the bionic adhesive pad 4 to prevent excessive deformation of the elastic material at the edge. When the material needs to be removed, the air pump 801 is started, and the air pump 801 pressurizes the air and delivers it to the fine nozzle 802, which then sprays it out. The fine nozzle 802 is aimed at the vent 7 to gradually make the material rise, and then It is easy to remove it from the bionic adhesive pad 4. After the bionic adhesive layer is removed, residual colloid of the double-sided adhesive layer 3 will remain on the positioning block 2. Turn the fixing nut 604 to make the fixing nut 604 move outward around the fixing screw 602, so that the distance between the fixing nut 604 and the nut becomes larger, so that the sleeve 601 can rotate on the fixing screw 602, and rotate the connecting block 506 by rotating the rotating shaft 505 so that the scraper 504 is aligned with the side of the positioning block 2 with residual colloid. Then tighten the fixing nut 604 to prevent the scraper 504 from being fixed on the connecting block 506. Then insert the pin 509 into the pin hole 508 to prevent the connecting block 506 from rotating during the cleaning process. Then pull the pull ring 507 to make the slider 502 slide in the scraping groove. The scraper 504 rotates with the slider 502 and the mounting block 503 to scrape off the residual colloid on the positioning block 2.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
