Description

Technical Field

[0001] This application relates to the field of adhesive removal technology, and more particularly to an adhesive removal device. Background Technology

[0002] Some small electronic products, such as headphones, require adhesive to hold various components together. A dispensing machine is primarily used to precisely dispense, inject, coat, or drip liquids such as adhesives onto specific locations on each product during manufacturing. After the adhesive solidifies, it completes the bonding process or forms a protective film. After a certain number of uses, residual adhesive accumulates on the dispensing needle, requiring cleaning by a wiping mechanism.

[0003] Currently, air-blowing adhesive removal mechanisms are commonly used to clean dispensing needles by blowing air to rub the needles and remove residual adhesive. However, existing air-blowing adhesive removal mechanisms are not effective at removing harder adhesive residues, requiring manual inspection and cleaning of the dispensing needles at regular intervals, resulting in low cleaning efficiency. Therefore, there is an urgent need for a fast, stable, and highly efficient adhesive removal device. Utility Model Content

[0004] This application provides a glue removal device that can efficiently clean residual glue from dispensing needles.

[0005] The adhesive removal device according to this application includes:

[0006] The housing has a de-adhesive hole and a first airflow channel and a second airflow channel inside the housing. The first airflow channel is used to allow airflow to flow into the housing, and the second airflow channel is used to allow airflow to flow out of the housing. During the process of airflow from the first airflow channel to the second airflow channel, a negative pressure is formed at the de-adhesive hole.

[0007] The adhesive removal device according to this application further includes a heating device, which is disposed outside or inside the housing and is used to heat the airflow entering the housing.

[0008] The adhesive removal device according to this application further includes an adhesive receiving cup that can enter and exit the interior of the housing, the opening of the adhesive receiving cup being opposite to the adhesive removal hole.

[0009] Optionally, the adhesive removal device further includes a base supporting the housing, the base being movably connected to a disc supporting the adhesive receiving cup.

[0010] According to the adhesive removal device of this application, the housing includes a cylindrical main body that extends through both ends, and a top cover that covers the top of the main body. The side wall of the main body has a cavity, and the top cover has an air outlet channel communicating with the cavity. The cavity and the air outlet channel define a first airflow channel. The inner cavity of the main body defines a second airflow channel. The adhesive removal hole is disposed on the top cover and communicates with the first airflow channel and the second airflow channel.

[0011] Optionally, multiple air outlet channels are provided, and the outlets of each air outlet channel surround the adhesive removal hole and are connected in sequence.

[0012] Optionally, the bottom of the main body is connected to an air inlet pipe that communicates with the cavity.

[0013] Optionally, the top cover is further provided with an adhesive suction channel communicating with the adhesive removal hole, the adhesive suction channel gradually narrowing in the direction from the second airflow channel toward the adhesive removal hole.

[0014] According to the adhesive removal device of this application, the heating device includes a heating part which is arranged around the outer side of the housing.

[0015] Optionally, the heating element is configured as an electromagnetic induction coil.

[0016] The technical solutions provided in this application have the following advantages compared with the prior art:

[0017] The adhesive removal device provided in this application embodiment has a first airflow channel and a second airflow channel inside the housing. The first airflow channel introduces airflow into the housing, while the second airflow channel discharges airflow out of the housing. The adhesive removal hole allows external airflow to flow into the housing. When the airflow enters the housing through the first airflow channel, it is heated by the heating device. On the one hand, the airflow accelerates within the first airflow channel, leading to a faster airflow velocity. Simultaneously, the static pressure of the airflow decreases. The rapid outflow of the airflow causes the air pressure at the adhesive removal hole to be lower than the surrounding atmospheric pressure, thus creating a negative pressure at the adhesive removal hole. When adhesive is applied... When the needle is inserted into the adhesive removal hole of the adhesive removal device, the negative pressure formed at the adhesive removal hole during the flow of air from the first airflow channel to the second airflow channel enables non-contact adhesive removal from the dispensing needle. On the other hand, the airflow is heated, and the hot airflow softens the residual adhesive on the dispensing needle. The softened residual adhesive is easier to detach than the hard residual adhesive, thus further facilitating the removal of residual adhesive. Thirdly, the adhesive receiving cup can effectively collect the residual adhesive falling into the housing from the adhesive removal hole, preventing the residual adhesive from falling directly into the interior of the housing. This helps to keep the adhesive removal device clean and tidy, and also facilitates better control of residual adhesive discharge, making it easier for subsequent processing or recycling.

[0028] 2. Dispensing needle. Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0031] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, the adhesive removal device according to this application includes: a housing 10.

[0033] Specifically, the housing 10 is provided with a de-adhesion hole 11, and the housing 10 is provided with a first airflow channel 12 and a second airflow channel 13. The first airflow channel 12 is used to allow airflow to flow into the housing 10, and the second airflow channel 13 is used to allow airflow to flow out of the housing 10. During the process of airflow from the first airflow channel 12 to the second airflow channel 13, a negative pressure is formed at the de-adhesion hole 11.

[0034] In detail, the housing 10 is provided with a first airflow channel 12 and a second airflow channel 13. The function of the first airflow channel 12 is to introduce airflow into the housing 10, while the function of the second airflow channel 13 is to discharge airflow from the housing 10. When the airflow enters the housing 10 from the first airflow channel 12, a negative pressure is formed at the adhesive removal hole 11 during the process of the airflow flowing from the first airflow channel 12 to the second airflow channel 13. This causes the external airflow to flow into the housing 10 through the adhesive removal hole 11. When the dispensing needle 2 is inserted into the adhesive removal hole 11 of the adhesive removal device, the driving force of the airflow flowing out of the first airflow channel 12 and the negative pressure formed at the adhesive removal hole 11 are used to achieve non-contact adhesive removal of the dispensing needle 2.

[0035] According to the adhesive removal device of this application embodiment, when the dispensing needle 2 is inserted into the adhesive removal hole 11 of the adhesive removal device, the force formed by the airflow flowing in the first airflow channel 12 and the negative pressure formed at the adhesive removal hole 11 can effectively achieve non-contact adhesive removal of the dispensing needle 2.

[0036] The adhesive removal device according to an embodiment of this application further includes a heating device 20, which is disposed outside or inside the housing 10 and is used to heat the airflow entering the housing 10. After being heated by the heating device 20, the airflow will accelerate within the first airflow channel 12. This acceleration will increase the airflow speed. As the airflow speed increases, the static pressure of the airflow decreases, making it easier to form a negative pressure at the adhesive removal hole 11. Furthermore, the heated airflow can soften harder residual adhesive, thereby improving the adhesive removal efficiency.

[0037] In some embodiments, the heating device 20 is disposed inside the housing 10, while in other embodiments, the heating device 20 is disposed outside the housing 10. This application does not impose any restrictions and the device can be configured as needed.

[0038] According to the adhesive removal device of this application embodiment, the heated airflow can both accelerate the flow and soften the hardened residual adhesive at the two dispensing needles. The softened residual adhesive is easier to remove than the hardened residual adhesive, thereby further facilitating the removal of residual adhesive. This avoids the need for regular manual inspection of the adhesive removal device or the possibility of manual adhesive removal when the adhesive removal force of other air blowing adhesive removal devices is insufficient.

[0039] The adhesive removal device according to the embodiments of this application further includes an adhesive receiving cup 30 that can enter and exit the interior of the housing 10, and the opening of the adhesive receiving cup 30 is opposite to the adhesive removal hole 11.

[0040] Understandably, the glue-receiving cup 30 can effectively collect residual glue falling into the housing 10 from the glue removal hole 11, preventing residual glue from falling directly into the interior of the housing 10. This helps to keep the glue removal device clean and tidy, and also facilitates better control of residual glue discharge, making it easier for later processing or recycling.

[0041] The adhesive removal device according to the embodiments of this application further includes a base 40 supporting the housing 10, and a disc 15 supporting the adhesive receiving cup 30 is movably connected to the base 40.

[0042] In detail, the disc 15 is movably connected to the base 40, so that the disc 15 and the base 40 can support the receiving cup 30 when connected. When the receiving cup 30 needs to be cleaned, the disc 15 and the base 40 can be separated and the receiving cup 30 can be taken out from below.

[0043] like Figure 2 As shown, in some embodiments, a glue-receiving cup 30 is provided in the second airflow channel 13. The opening of the glue-receiving cup 30 avoids the outlet of the first airflow channel 12, thus preventing interference with the formation of negative pressure in the first airflow channel 12 at the glue removal hole 11.

[0044] In some embodiments, the plurality of exhaust holes 151 on the disc 15 are connected to the second airflow channel 13, which can effectively exhaust excess gas. The plurality of exhaust holes 151 are arranged around the glue receiving cup 30, which can effectively avoid dead zones in the airflow, while allowing the collected residual glue to flow freely into the glue receiving cup 30, reducing interference with the airflow.

[0045] The number of exhaust holes 151 can be determined according to the airflow velocity and volumetric flow rate. An appropriate number of exhaust holes 151 can ensure the uniform distribution of airflow and avoid local overpressure or negative pressure. The shape of the exhaust holes 151 can be circular, elliptical or other shapes. Circular holes are preferred because they perform better in stress distribution.

[0046] like Figure 2 As shown, according to an embodiment of the present application, the adhesive removal device includes a housing 10 comprising a cylindrical main body 16 with both ends through, and a top cover 17 covering the top of the main body 16. The side wall of the main body 16 has a cavity 1201, and the top cover 17 has an air outlet channel 1202 communicating with the cavity 1201. The cavity 1201 and the air outlet channel 1202 define a first airflow channel 12, and the inner cavity of the main body 16 defines a second airflow channel 13. An adhesive removal hole 11 is disposed on the top cover 17 and communicates with the first airflow channel 12 and the second airflow channel 13.

[0047] This design effectively reduces the overall height and volume of the adhesive removal device. At the same time, it allows the airflow in the first airflow channel 12 and the second airflow channel 13 to effectively exchange heat with the heating device 20, increasing the airflow temperature. This allows the flowing gas to reach a higher temperature, which helps improve the adhesive removal effect. The adhesive removal hole 11 is located on the top cover 17, which facilitates processing.

[0048] like Figure 2 and Figure 3 As shown, in one specific embodiment, the adhesive receiving cup 30 is inserted into the main body 16. The cross-sectional shapes of the adhesive receiving cup 30, the main body 16, and the outer shell are all circular; of course, the cross-sectional shape of the adhesive receiving cup 30 can also be square, elliptical, rectangular, etc. The cross-sectional shape of the main body 16 can also be square, elliptical, rectangular, etc. The cross-sectional shape of the outer shell can also be square, elliptical, rectangular, etc.

[0049] like Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, multiple air outlet channels 1202 are provided, and the outlet of each air outlet channel 1202 surrounds the adhesive removal hole 11 and is connected in sequence.

[0050] This design enhances airflow attraction and facilitates the formation of vortices, resulting in stronger negative pressure at the adhesive removal hole 11. This helps to better remove adhesive or other substances, improving the overall adhesive removal effect of the device. Furthermore, the multiple air outlets 1202 with outlets 121 create vortices, further enhancing adhesive removal efficiency.

[0051] like Figure 4 and Figure 5 As shown, in a specific embodiment, there are four air outlet channels 1202, and the four outlets 121 are arranged in a circle and connected end to end, so as to better form a vortex.

[0052] like Figure 2 As shown, in the adhesive removal device according to the embodiment of this application, the bottom of the main body 16 is connected to an air inlet pipe 18 that communicates with the cavity 1201, so that airflow can be introduced into the cavity 1201 through the air inlet pipe 18.

[0053] In some embodiments, the top cover 17 is further provided with an adhesive suction channel 14 communicating with the adhesive removal hole 11, the adhesive suction channel 14 gradually narrowing in the direction from the second airflow channel 13 toward the adhesive removal hole 11.

[0054] like Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, the housing 10 is also provided with a suction channel 14, which is connected to and coaxially arranged with the adhesive removal hole 11. The diameter of the suction channel 14 gradually decreases in the direction from the second airflow channel 13 toward the adhesive removal hole 11.

[0055] In detail, the adhesive suction channel 14 is connected to the adhesive removal hole 11. Through the principle of negative pressure, it can effectively remove adhesive or adhering substances from the material surface. For example, when the dispensing needle 2 is inserted into the adhesive removal hole 11, it can remove adhesive from the dispensing needle 2, which is more conducive to forming negative pressure at the adhesive removal hole 11. In the direction from the second airflow channel 13 toward the adhesive removal hole 11, the adhesive suction channel 14 gradually narrows, which can accelerate the airflow when it flows toward the adhesive removal hole 11, thereby increasing the speed and kinetic energy of the airflow, which helps to enhance the impact and adsorption of the airflow on the adhesive, and further improve the adhesive removal ability.

[0056] In some embodiments, the adhesive suction channel 14 and the adhesive removal hole 11 are coaxially arranged, which can reduce airflow turbulence and make the airflow more concentrated and smooth when passing through the adhesive suction channel 14, thereby improving adhesive removal efficiency.

[0057] In some specific embodiments, the adhesive suction channel 14 and the second airflow channel 13 are also coaxially arranged.

[0058] like Figure 2 As shown, in the adhesive removal device according to an embodiment of this application, the heating device 20 includes a heating part, which is disposed around the outer side of the housing 10.

[0059] Understandably, placing the heating device 20 outside the housing 10 can reduce the direct impact of high temperature on internal components, help extend the service life of the equipment, and reduce potential safety hazards caused by internal heating. The heating element is coiled around the outside of the housing 10, making it easier to monitor and adjust the temperature, facilitate real-time monitoring of the heating effect, ensure that the airflow reaches the required temperature conditions, and also make maintenance and replacement easier.

[0060] The heating element can be a resistance wire or an electric heating film, or it can be an infrared radiation element, a heat conduction element, or an electromagnetic heating element, etc., depending on the requirements.

[0061] In some embodiments, the heating element is configured as an electromagnetic induction coil.

[0062] Specifically, electromagnetic induction coil heating generates heat directly inside the metal material without the need for conduction through a medium, which can generate heat rapidly and is usually faster than methods such as resistance heating. At the same time, electromagnetic induction coil heating has a high energy conversion efficiency and low heat loss. Furthermore, electromagnetic induction coil heating can achieve precise temperature control, which is more conducive to selecting the appropriate heating temperature based on the melting point of the adhesive to be removed.
