Description

Technical Field

[0001] This invention belongs to the technical field of conformal coating equipment, and particularly relates to a conformal coating equipment for electronic equipment processing. Background Technology

[0002] Conformal adhesive is a polymer coating applied to the surface of electronic products and their internal components. After curing, the coating forms a protective film to prevent moisture, salt spray, and mildew, while also providing insulation, dustproofing, and vibration resistance.

[0003] When applying conformal coating to electronic products, spraying is commonly used to achieve a thin coating. However, conventional conformal coating spraying equipment often uses a fixed nozzle structure, and the distance between the nozzle and the product to be coated (due to the fixed position of the product carrier) is also constant. This makes it difficult to adapt to different types of electronic products on a single machine, and also prevents the application of different amounts and thicknesses of conformal coating to different parts of the electronic product.

[0004] Furthermore, conventional conformal coating spraying equipment typically pressurizes liquid conformal coating and outputs it to nozzles. The high-pressure conformal coating passes through the narrow nozzle outlet and is squeezed into a fan-shaped (or cone-shaped) spray. Because the distance between each spray point and the nozzle is different, the conformal coating content and spray force at the edge of the spray are different from other parts, resulting in uneven spraying and affecting the conformal coating effect. Summary of the Invention

[0005] The purpose of this invention is to provide a conformal coating equipment for electronic device processing to solve the technical problems described in the background art.

[0006] The aforementioned conformal coating equipment for electronic device processing includes:

[0007] Carrier, used to hold electronic products to be coated with conformal coating;

[0008] The lifting device is driven by an isolation cover, and a spraying device is installed inside the isolation cover. The spraying device is equipped with a slide and a conformal coating atomizing nozzle. The outer wall of the slide has an array of several coil units that can generate a magnetic field. A conical guide slides inside the slide, with the large-diameter end of the conical guide facing the conformal coating atomizing nozzle. A first magnet is provided on the outer periphery of the conical guide. The slide has a conformal coating recovery channel for recovering conformal coating that has not been sprayed out from the conical guide.

[0009] When the lifting device drives the isolation cover to descend and cover the electronic product, the small-diameter end of the tapered conduit faces the electronic product. When the conformal coating atomizing nozzle sprays out conformal coating, the coil unit drives the first magnet to move the tapered conduit. The distance between the tapered conduit and the conformal coating atomizing nozzle or the distance between the tapered conduit and the electronic product is adjusted so that the conformal coating is evenly gathered at a certain point of the electronic product or diffused to cover a certain side of the electronic product.

[0010] Based on the above technical solution, the present invention achieves the following beneficial effects:

[0011] 1. This conformal coating spraying equipment can control the atomized airflow of conformal coating sprayed from the nozzle to converge or diffuse onto the electronic product by adjusting the distance between the conical guide tube and the conformal coating atomizing nozzle or the distance between the nozzle and the electronic product. Therefore, while maintaining a constant distance between the nozzle and the product to be coated, the thickness, content, and coverage of the conformal coating can be adjusted, thus adapting to different types of electronic products and enabling the spraying of conformal coatings with different contents, thicknesses, and densities onto different parts of the electronic product.

[0012] 2. Because the edge of the fan-shaped conformal spray from the conformal spray nozzle is blocked by the inner wall of the conical guide tube, while the central part of the fan-shaped conformal spray passes through the conical guide tube and is sprayed onto the product, the conformal adhesive can be evenly sprayed onto the electronic product.

[0013] 3. Because the conformal coating atomizing nozzle needs to be connected to the raw material pipeline and power line, it is not convenient to drive the conformal coating atomizing nozzle to approach or move away from the electronic product at high speed and stably. However, the conical guide tube of this conformal coating spraying equipment does not need to be connected to any pipeline or line. Therefore, by driving the conical guide tube to move, the conformal coating can be evenly and stably gathered at a certain point of the electronic product or diffused to cover a certain side of the electronic product.

[0014] 4. After the conformal coating atomizing nozzle finishes its work, there will generally be conformal coating residue. The slide rail design can effectively prevent the conformal coating residue on the conformal coating atomizing nozzle from dripping.

[0015] 5. When the conformal coating atomizing nozzle is used again, it will also spray the residual conformal coating forward, which will result in uneven coating or spray the conformal coating onto areas of electronic products that do not need to be coated. The tapered guide tube can prevent the conformal coating atomizing nozzle from spraying the residual conformal coating.

[0016] To further optimize the above technical solutions, they can be combined with one or more of the following implementation methods without conflict.

[0017] In some embodiments, the conformal coating atomizing nozzle is mounted on an adjusting plate that can slide within a slide rail, and a second magnet is mounted on the adjusting plate;

[0018] The coil unit drives the second magnet to move the adjustment plate, so that the conformal coating atomizing nozzle is aligned or shifted, moved away from or closer to the hole of the tapered guide tube, or paralleled or tilted, so as to adjust the effect of the conformal coating being sprayed from the tapered guide tube onto the electronic product.

[0019] Based on the above technical solution, the present invention further achieves the following beneficial effects:

[0020] 1. By controlling the position of the conformal coating atomizing nozzle, the conformal coating atomizing nozzle can be aligned with or moved away from, moved closer to or away from, parallel to or tilted to the conical guide tube. This allows control over the area of ​​the fan-shaped conformal coating sprayed from the conical guide tube when the conformal coating atomizing nozzle sprays out a fan-shaped conformal coating spray, thereby adjusting the effect of the conformal coating sprayed onto electronic products.

[0021] 2. When applying conformal coating to the inclined surface of electronic products, the coil unit can drive the second magnet to move and tilt the adjustment plate, so that the conformal coating atomizing nozzle can be in an inclined state, thereby enabling the conformal coating to be sprayed onto the electronic products more evenly.

[0022] In some implementations, the regulating plate is equipped with a booster nozzle;

[0023] The booster nozzle is used to supply high-pressure gas into the slide. When the conformal coating atomizing nozzle sprays out conformal coating, the conformal coating is output from the conical duct along the airflow and impacts the electronic product.

[0024] Based on the above technical solution, the present invention further achieves the following beneficial effects:

[0025] 1. The conformal coating sprayed from the tapered nozzle allows it to adhere more stably to electronic products;

[0026] 2. It can reduce the amount of conformal adhesive that falls or spreads on the way from the tapered nozzle onto the electronic product, thus making the amount of conformal adhesive sprayed onto the electronic product more stable.

[0027] In some implementations, when residual conformal coating remains on the slide, the coil unit drives the first magnet to move to scrape the residual conformal coating off the slide. The booster nozzle is used to supply high-pressure air into the slide, and the scraped conformal coating is sent out of the slide with the airflow, thereby cleaning the slide.

[0028] In some embodiments, a rotary drive module and a rotary joint are installed inside the isolation cover. The rotary drive module drives a bracket, and a spraying device is mounted on the bracket. The spraying device is equipped with a distance measuring instrument for detecting the distance between itself and the electronic product or a vision camera for locating the local position of the electronic product.

[0029] The lifting device drives the isolation cover to position the spraying device at different heights around the electronic product. The rotation drive module is used to drive the bracket to rotate the spraying device around the electronic product at different heights.

[0030] Based on the above technical solution, the present invention further achieves the following beneficial effects:

[0031] 1. Capable of applying conformal coating to the entire periphery of electronic products;

[0032] 2. When the spraying device is driven to rotate around the outer periphery of the electronic product, the position of the conformal coating atomizing nozzle and the conical guide can be adjusted according to the distance between the spraying device and the electronic product or by positioning the local position of the electronic product, so as to spray different contents, thicknesses and densities of conformal coating on different parts of the electronic product.

[0033] In some embodiments, the bracket is equipped with a lateral drive module for driving the spraying device to move laterally.

[0034] Based on the above technical solution, the present invention further achieves the following beneficial effects:

[0035] 1. It can adjust the position between the spraying device and the electronic product according to different types and shapes of electronic products, as well as different parts of the electronic products, so that the spraying device can evenly spray the conformal coating onto the electronic products and irregular parts of the electronic products.

[0036] 2. When the lateral drive module drives the spraying device to move laterally, adjust the position of the conformal coating atomizing nozzle and the conical guide tube to spray conformal coating with different contents, thicknesses and densities for different parts of the electronic product, and to spray conformal coating more evenly to irregularly shaped parts.

[0037] In some embodiments, a support slip ring is installed on the top of the isolation cover, and a plurality of conductive slip rings are provided on the support slip ring. A support rod is provided in the middle of the bracket, which is mounted on the support slip ring and can slide on the support slip ring. The support rod is provided with a conductive pulley that contacts the conductive slip ring. The transverse drive module and the coil unit are electrically connected to the conductive pulley.

[0038] Based on the above technical solution, the present invention further achieves the following beneficial effects:

[0039] 1. Since the spraying device generates a certain amount of thrust and vibration when spraying the conformal coating, the bracket is supported by the support rod and the slip ring to support and limit the spraying device, so that the spraying device can spray the conformal coating onto the electronic product more stably, and the rotary drive module can drive the bracket to rotate the spraying device around the outer periphery of the electronic product more stably.

[0040] 2. Because the support slip ring is equipped with several conductive slip rings, and the support rod is equipped with conductive pulleys that contact the conductive slip rings, and the transverse drive module and coil unit are electrically connected to the conductive pulleys, the coil unit and transverse drive module can be electrically connected to the control host without the need for cables. This avoids cable tangling when the rotation drive module drives the bracket to move the spraying device around the electronic product more stably.

[0041] In some embodiments, the conformal coating equipment also includes a cabinet with a conveyor belt installed inside, which can be connected to other processing stations. The conveyor belt is used to move electronic products under the enclosure and to drive the electronic products to move longitudinally within the enclosure.

[0042] Based on the above technical solution, the present invention further achieves the following beneficial effects:

[0043] 1. By setting up a conveyor belt to connect this conformal coating spraying equipment with other processing stations, manual handling can be reduced and the overall efficiency of the production line can be improved when processing electronic products.

[0044] 2. The electronic product is driven to move longitudinally within the isolation cover by a conveyor belt, while the spraying device is driven to move laterally by a transverse drive module and rotated around the electronic product by a rotation drive module. This allows the spraying device to be moved to various parts of the outer periphery of the electronic product. In addition, by adjusting the position of the conformal adhesive atomizing nozzle and the conical guide tube, different contents, thicknesses and densities of conformal adhesive can be sprayed onto different parts of the electronic product.

[0045] In some embodiments, the outer casing of the spraying device is provided with a magnetic field shielding layer; the electronic product is provided with an information board, the information board is provided with a magnetic layer, the magnetic layer is provided with a corresponding magnetic field according to the vibration frequency and pattern of the sound, and the conveyor belt is equipped with a recording and playback magnetic head;

[0046] As the conveyor belt drives the electronic product to move, the information board passes by the recording and playback head. The recording and playback head obtains an analog signal of sound by sensing the magnetic field and / or changes the magnetic field according to another analog signal of sound, so as to obtain the processing information of the electronic product and write the current processing information according to the analog signal of sound.

[0047] Based on the above technical solution, the present invention further achieves the following beneficial effects:

[0048] 1. When electronic products are moving along the conveyor line and at other workstations besides the conformal coating equipment, the analog signal of the sound recorded on the information board set on the electronic product is read by the recording and playback head, thereby realizing the positioning and registration of processing information of the electronic product;

[0049] 2. Since the information board records the analog signal of sound through the magnetic field of the magnetic layer, and the recording and playback head can obtain the processing information of the electronic product and write the current processing information according to the analog signal of sound, all the processing information, test information and other contents of the electronic product can be recorded and stored on the product body, thereby reducing the storage load of the production line server.

[0050] 3. Since the recording and playback head obtains the analog signal of sound by sensing the magnetic field and / or changes the magnetic field according to the analog signal of another sound, when the conformal coating applied to the product is colored, it can avoid the conformal coating covering or obscuring the information board and thus preventing the electronic product information from being obtained. Even if the conformal coating applied to the electronic product is transparent, it can also avoid the inability to read the information board due to the reflection or refraction of the conformal coating.

[0051] In some implementations, the sound is composed of several audio tracks with different timbres, durations, pitches, and loudnesses superimposed on each other. After the recording / playback head reads the analog signal, it decomposes and reconstructs each audio track according to the rules of timbre, duration, pitch, and loudness to obtain the processing information. Furthermore, by varying the speed of the audio tracks, the sound content recorded within the magnetic field is compressed.

[0052] According to the above technical solution, the amount of information recorded on the information board can be increased and the area of ​​the information board can be reduced. Attached Figure Description

[0062] To make the objectives, technical solutions, and advantages of this invention clearer, the following description is provided with reference to the accompanying drawings.

[0063] like Figures 1 to 6 As shown, the above-mentioned conformal coating equipment for electronic device processing includes: a carrier 1 and a lifting device 2.

[0064] The carrier 1 is used to place the electronic product 12 to be coated with conformal coating. The carrier 1 can lift the electronic product 12 to a certain height. The lifting device 2 drives the isolation cover 21. The spraying device 3 is installed inside the isolation cover 21. The spraying device 3 is equipped with a slide 31 and a conformal coating atomizing nozzle 32. The outer wall of the slide 31 is arrayed with several coil units 33 that can generate a magnetic field. A conical guide tube 34 slides inside the slide 31. The large diameter end of the conical guide tube 34 faces the conformal coating atomizing nozzle 32. A first magnet 341 is provided on the outer periphery of the conical guide tube 34. The slide 31 is equipped with a conformal coating recovery channel. The conformal coating recovery channel can be a component for sucking out the conformal coating from the slide 31 (such as a vacuum cleaner) or a drainage pipe for collecting the conformal coating sucked out of the slide 31, so that the conformal coating recovery channel can recover the conformal coating that has not been sprayed out from the conical guide tube 34.

[0065] When the lifting device 2 drives the isolation cover 21 to lower and cover the electronic product 12, the small-diameter end of the tapered guide tube 34 faces the electronic product 12. When the conformal coating atomizing nozzle 32 sprays out conformal coating, the coil unit 33 drives the first magnet 341 to move the tapered guide tube 34. The distance between the tapered guide tube 34 and the conformal coating atomizing nozzle 32 or the distance between the tapered guide tube 34 and the electronic product 12 is adjusted so that the conformal coating is evenly gathered at a certain point of the electronic product 12 or diffused to cover a certain side of the electronic product 12.

[0066] This conformal coating spraying equipment can control the atomized airflow of conformal coating sprayed from the atomizing nozzle 32 to converge or diffuse onto the electronic product 12 by adjusting the distance between the conical guide tube 34 and the conformal coating atomizing nozzle 32, or between the nozzle and the electronic product 12. Therefore, when the product to be coated is placed on a fixed carrier, a constant distance is maintained between the nozzle and the product, and the thickness, content, and coverage of the conformal coating can be adjusted. This allows it to be adapted to different types of electronic products 12, and to spray different contents, thicknesses, and densities of conformal coating onto different parts of the electronic product 12.

[0067] Because the edge of the fan-shaped conformal spray from the conformal atomizing nozzle 32 is blocked by the inner wall of the conical guide tube 34, while the central part of the fan-shaped conformal spray passes through the conical guide tube 34 and is sprayed onto the product, the conformal adhesive can be evenly sprayed onto the electronic product 12.

[0068] In addition, after the conformal coating atomizing nozzle 32 finishes its work, conformal coating residue is usually left at the outlet. The slide 31 can effectively prevent the residual conformal coating on the conformal coating atomizing nozzle 32 from dripping. At the same time, the conformal coating atomizing nozzle 32 will also spray the residual conformal coating forward during the next operation, which will result in uneven coating or spray conformal coating onto areas of the electronic product 12 that do not need to be coated. The conical guide tube 34 can effectively prevent the conformal coating atomizing nozzle 32 from spraying the residual conformal coating.

[0069] In some embodiments, the conformal coating atomizing nozzle 32 is mounted on an adjusting plate 321 that can slide within a slide rail 31, and a second magnet 322 is mounted on the adjusting plate 321. The second magnet 322 is driven by the coil unit 33 to move the adjusting plate 321, thereby aligning or shifting, moving away from or closer to, paralleling or tilting the conformal coating atomizing nozzle 32 with the orifice of the tapered conduit 34, in order to adjust the effect of the conformal coating being sprayed from the tapered conduit 34 onto the electronic product 12.

[0070] Therefore, by controlling the position of the conformal coating atomizing nozzle 32, the conformal coating atomizing nozzle 32 can be aligned or shifted, moved away from or closer to the hole of the conical guide tube 34, or made parallel or tilted. Thus, when the conformal coating atomizing nozzle 32 sprays out a fan-shaped conformal coating spray, the part of the fan-shaped conformal coating sprayed from the conical guide tube 34 can be controlled to adjust the effect of the conformal coating sprayed onto the electronic product 12.

[0071] When applying conformal coating to the inclined surface of the electronic product 12, the second magnet 322 can be driven by the coil unit 33 to move and tilt the adjustment plate 321, so that the conformal coating atomizing nozzle 32 can be in an inclined state, thereby enabling the conformal coating to be sprayed onto the electronic product 12 more evenly.

[0072] In some embodiments, the regulating plate 321 is equipped with a booster nozzle 323; the booster nozzle 323 is used to supply high-pressure gas into the slide 31, and when the conformal coating atomizing nozzle 32 sprays out conformal coating, the conformal coating is output from the conical duct 34 along the airflow and impacts the electronic product 12.

[0073] Therefore, the conformal coating sprayed from the tapered conduit 34 allows it to adhere more stably to the electronic product 12. Simultaneously, it reduces the amount of conformal coating that may fall off or spread during its journey from the tapered conduit 34 onto the electronic product 12, thus ensuring a more stable conformal coating content on the electronic product 12.

[0074] In some embodiments, when residual conformal coating remains on the slide 31, the coil unit 33 drives the first magnet 341 to move, so as to scrape the residual conformal coating off the slide 31. The pressurized air nozzle 323 is used to input high-pressure air into the slide 31, and the scraped conformal coating is sent out of the slide 31 with the airflow, thereby cleaning the slide 31.

[0075] In some embodiments, a rotary drive module 4 and a rotary joint are installed inside the isolation cover 21. The rotary drive module 4 drives a bracket 40. A spraying device 3 is mounted on the bracket 40. A conformal adhesive atomizing nozzle 32 is connected to the rotary joint pipe. The spraying device 3 is equipped with a distance measuring instrument for detecting the distance between itself and the electronic product 12 or a vision camera for locating the local position of the electronic product 12.

[0076] The lifting device 2 drives the isolation cover 21 to position the spraying device 3 at different heights around the outer periphery of the electronic product 12. The rotation drive module 4 drives the bracket 40 to rotate the spraying device 3 around the outer periphery of the electronic product 12 at different heights. Therefore, it is possible to spray conformal adhesive all around the outer periphery of the electronic product 12.

[0077] When the spraying device 3 is driven to rotate around the outer periphery of the electronic product 12, the position of the conformal coating atomizing nozzle 32 and the conical guide tube 34 can be adjusted according to the distance between the spraying device 3 and the electronic product 12 or by positioning the local position of the electronic product 12, so as to spray conformal coatings with different contents, thicknesses and densities on different parts of the electronic product 12.

[0078] In some embodiments, the bracket 40 is equipped with a transverse drive module 41, which drives the spraying device 3 to move laterally. Therefore, the position between the spraying device 3 and the electronic product 12 can be adjusted according to different types and shapes of electronic products 12, and according to different parts of the electronic product 12, so that the spraying device 3 can uniformly spray conformal adhesive onto the electronic product 12 and irregular parts of the electronic product 12.

[0079] Furthermore, when the lateral drive module 41 drives the spraying device 3 to move laterally, the positions of the conformal coating atomizing nozzle 32 and the conical guide tube 34 are adjusted, thereby spraying conformal coatings of different contents, thicknesses and densities onto different parts of the electronic product 12, and enabling more uniform spraying of conformal coatings onto irregularly shaped parts.

[0080] In some embodiments, a support slip ring 42 is installed on the top of the isolation cover 21. The support slip ring 42 is provided with a plurality of conductive slip rings. The middle part of the bracket 40 is provided with a support rod 43 that is hung on the support slip ring 42 and can slide on the support slip ring 42. The support rod 43 is provided with a conductive pulley that contacts the conductive slip rings. The transverse drive module 41 and the coil unit 33 are electrically connected to the conductive pulley.

[0081] Since the spraying device 3 generates a certain amount of thrust and vibration when it sprays out the conformal coating, the bracket 40 is supported by the support rod 43 and the support slip ring 42 is hung on it to support and limit the spraying device 3. This allows the spraying device 3 to spray the conformal coating onto the electronic product 12 more stably, and allows the rotary drive module 4 to drive the bracket 40 to rotate the spraying device 3 around the outer periphery of the electronic product 12 more stably.

[0082] Furthermore, since the support slip ring 42 is provided with several conductive slip rings, and the support rod 43 is provided with conductive pulleys that contact the conductive slip rings, and the transverse drive module 41 and the coil unit 33 are electrically connected to the conductive pulleys, the coil unit 33 and the transverse drive module 41 can be electrically connected to the control host without the need for cables. This prevents the cables from getting tangled when the rotation drive module 4 drives the bracket 40 to move the spraying device 3 around the electronic product 12 more stably.

[0083] In some embodiments, the conformal coating equipment further includes a cabinet 6, which is equipped with a conveyor belt 5 that can be connected to other processing stations. The conveyor belt 5 is used to move the electronic product 12 to the bottom of the isolation cover 21 and to drive the electronic product 12 to move longitudinally within the isolation cover 21.

[0084] Therefore, by setting up conveyor belt 5 to connect the conformal coating equipment with other processing stations, manual handling is reduced and the overall efficiency of the production line is improved when processing electronic products 12.

[0085] Furthermore, the electronic product 12 is driven to move longitudinally within the isolation cover 21 by the conveyor belt 5, while the spraying device 3 is driven to move laterally by the transverse drive module 41, and the spraying device 3 is driven to rotate around the electronic product 12 by the rotation drive module 4, thereby moving the spraying device 3 to various parts of the outer periphery of the electronic product 12. In addition, by adjusting the position of the conformal coating atomizing nozzle 32 and the conical guide tube 34, conformal coatings of different contents, thicknesses and densities can be sprayed onto different parts of the electronic product 12.

[0086] In some embodiments, the outer shell of the spraying device 3 is provided with a magnetic field shielding layer; the electronic product 12 is provided with an information board, the information board is provided with a magnetic layer, the magnetic layer is provided with a corresponding magnetic field according to the vibration frequency and law of the sound, and the conveyor belt 5 is equipped with a recording and playback magnetic head 51.

[0087] As the conveyor belt 5 drives the electronic product 12 to move, the information plate passes by the recording and playback head 51. The recording and playback head 51 obtains an analog sound signal by sensing the magnetic field and / or changes the magnetic field according to another analog sound signal, thereby realizing the acquisition of the processing information of the electronic product 12 based on the analog sound signal and the writing of the current processing information. This achieves the positioning and registration of processing information for the electronic product 12.

[0088] Since the information board records analog sound signals through the magnetic field of a magnetic layer, and the recording / playback head 51 can acquire the processing information of the electronic product 12 and write the current processing information based on the analog sound signal, all processing information, test information, and other content of the electronic product 12 can be recorded and stored on the product itself, thereby reducing the storage load on the production line server. The sound can be voice or audio content, which can be recognized and converted into text content using existing computer applications.

[0089] Furthermore, since the recording and playback head 51 obtains an analog signal of sound by sensing a magnetic field and / or changes the magnetic field according to another analog signal of sound, when the conformal coating applied to the product is colored conformal coating, it can prevent the conformal coating from covering or obscuring the information board and thus preventing the electronic product 12 from being unable to obtain information. Even if the conformal coating applied to the electronic product 12 is transparent conformal coating, it can also prevent the information board from being unreadable due to the conformal coating reflecting or refracting light.

[0090] In some embodiments, the sound is composed of several audio tracks with different timbres, durations, pitches, and loudnesses superimposed on each other. After the recording / playback head 51 reads the analog signal, it decomposes and reconstructs each audio track according to the rules of timbre, duration, pitch, and loudness to obtain the processed information. Furthermore, by varying the speed of the audio tracks, the sound content recorded within the magnetic field is compressed. This increases the amount of information recorded on the information board and reduces the area of ​​the information board.

[0091] To further explain the stamping equipment with multiple stamping positions described in this specific embodiment, the following examples are provided.

[0092] Example 1

[0093] This embodiment provides a conformal coating equipment for electronic equipment processing, which includes a cabinet 6, a carrier 1, and a lifting device 2.

[0094] The cabinet 6 is equipped with a conveyor belt 5 that can be connected to other processing stations. The conveyor belt 5 is used to move the carrier 1. The carrier 1 is used to place electronic products 12 to be coated with conformal adhesive.

[0095] The lifting device 2 drives an isolation cover 21, inside which a spraying device 3 is installed. The spraying device 3 contains a slide rail 31 and a conformal coating atomizing nozzle 32. The outer wall of the slide rail 31 is arrayed with several coil units 33 capable of generating a magnetic field. A tapered guide tube 34 slides within the slide rail 31, with its larger diameter end facing the conformal coating atomizing nozzle 32. A first magnet 341 is located on the outer periphery of the tapered guide tube 34. The conformal coating atomizing nozzle 32 is connected to a pipeline for connection to a conformal coating supply device.

[0096] The following is a description of the operation of the conformal coating equipment mentioned in this embodiment.

[0097] The conveyor belt 5 moves the electronic product 12 to below the isolation cover 21. Then, the lifting device 2 drives the isolation cover 21 to descend and cover the electronic product 12. At this time, the smaller diameter end of the tapered guide tube 34 faces the electronic product 12, and the conformal coating atomizing nozzle 32 sprays conformal coating. The coil unit 33 drives the first magnet 341 to move the tapered guide tube 34, adjusting the distance between the tapered guide tube 34 and the conformal coating atomizing nozzle 32 or between the tapered guide tube 34 and the electronic product 12 to evenly concentrate the conformal coating at a point on the electronic product 12 or diffuse it to cover a surface of the electronic product 12. Afterwards, the lifting device 2 drives the isolation cover 21 to rise and reset. Then, the conveyor belt 5 moves the electronic product 12 away from below the isolation cover 21.

[0098] Example 2

[0099] This embodiment provides a conformal coating equipment for electronic equipment processing, which includes a cabinet 6, a conveyor belt 5 and a lifting device 2 installed inside the cabinet 6.

[0100] The conveyor belt 5 can be connected to other processing stations besides the conformal coating equipment. The conveyor belt 5 carries a carrier 1, which is used to place the electronic product 12 to be coated with conformal coating.

[0103] The following is a description of the operation of the conformal coating equipment described in this embodiment.

[0104] The conveyor belt 5 moves the carrier 1 to transport the electronic product 12 to below the isolation cover 21. Then, the lifting device 2 lowers the isolation cover 21 to cover the electronic product 12, at which point the spraying device 3 is positioned beside the electronic product 12. Subsequently, the electronic product 12 is driven longitudinally within the isolation cover 21 by the conveyor belt 5, the spraying device 3 is driven laterally by the lateral drive module 41, and the spraying device 3 is driven to rotate around the electronic product 12 by the rotation drive module 4. The lifting device 2 drives the isolation cover 21 to raise and lower the spraying device 3, moving it to various locations around the outer periphery of the electronic product 12. At this time, the conformal adhesive atomizing nozzle 32 sprays conformal adhesive spray, and the pressurizing nozzle 323 supplies high-pressure gas into the slide 31. The conformal adhesive spray is then output from the conical duct 34 following the airflow. And impact the electronic product 12; during the spraying of conformal coating from the conformal coating atomizing nozzle 32, depending on the position of the spraying device 3 on the electronic product, the coil unit 33 drives the first magnet 341 to move the conical guide tube 34, adjusting the distance between the conical guide tube 34 and the conformal coating atomizing nozzle 32 or the distance between the conical guide tube 34 and the electronic product 12, aligning or shifting, moving away from or closer to, parallel or tilting the conformal coating atomizing nozzle 32 and the conical guide tube 34, so that the conformal coating spray is evenly concentrated at a certain point of the electronic product 12 or diffused to cover a certain side of the electronic product 12.

[0108] As the conveyor belt 5 drives the electronic product 12 to move, the information board passes by the recording / playback head 51. The recording / playback head 51 obtains an analog signal of sound by sensing the magnetic field and / or changes the magnetic field according to another analog signal of sound, so as to obtain the processing information of the electronic product 12 and write the current processing information according to the analog signal of sound. The sound is composed of several audio tracks with different timbres, durations, pitches, and loudnesses superimposed. After reading the analog signal, the recording / playback head 51 deconstructs and reconstructs each audio track according to the rules of timbres, durations, pitches, and loudnesses to obtain the processing information. The sound content recorded in the magnetic field can be compressed by changing the speed of the audio tracks.
