Description

Technical Field

[0001] This invention relates to the field of goggle manufacturing technology, specifically to a glue-coating device for goggle manufacturing. Background Technology

[0002] Applying adhesive is usually required during the production of goggles. This is a key step in the assembly process. During production, a special dispensing machine is used to apply adhesive to the outline of the frame to firmly bond the lens to the frame. At the same time, the joints between the TPU frame and different materials such as sponge, EVA and ABS also need to be sealed with adhesive to ensure the sealing and comfort of wearing the goggles.

[0003] Publication No. CN212883286U discloses an eyeglass frame adhesive application device that enables soft contact between the device and the frame, effectively preventing damage to uneven application areas. A compression spring is installed between the connector base plate and the lower mounting plate to promptly reset the guide pin shaft in an unbalanced or misaligned state, achieving automated high-low positioning adhesive application. This ensures the guide pin shaft remains in constant contact with the application area, significantly improving the uniformity of the adhesive application. It can handle adhesive application for eyeglass frames of various structural specifications, offering wide applicability. Its novel structure and high stability contribute to improving the quality of the frame-lens connection process. However, this patent still has the following problems in practical use: While this eyeglass frame adhesive applicator can achieve soft contact between the applicator and the eyeglass frame, effectively avoiding damage to areas with varying adhesive application points, the uniformity of the adhesive application is crucial. Since goggles require a small amount of adhesive to be evenly sprayed along the inner side of the frame, this process is critical. If air bubbles are not removed from the adhesive layer, air pockets can form, or the application path can be interrupted, directly reducing the bond strength between the lens and the frame. This can lead to air leakage, uncontrolled adhesive application, excessively thick adhesive layers forming "adhesive nodules," or insufficient adhesive covering the bonding area, resulting in loose lens fixation and seal failure. Existing technologies use centrifugation to remove air bubbles, but this is ineffective for high-viscosity adhesives and other materials. Centrifugation alone cannot completely remove deep, tiny air bubbles, potentially leaving stubborn bubbles with a diameter less than 0.1 mm, failing to meet the bubble-free requirements for high-precision adhesive application on goggles.

[0004] Therefore, a glue-coating device for goggle production is proposed to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a glue-applying device for goggle production, addressing the issues raised in the background art. When applying glue to goggle frames, goggles require a small amount of glue to be evenly sprayed along the inner side of the frame, thus demanding high uniformity in the application. If air bubbles within the glue layer are not removed, air pockets may form within the glue layer, or the glue application path may be interrupted, directly reducing the bonding strength between the lens and the frame. This can easily lead to air leakage through gaps, uncontrolled glue dispensing, excessively thick glue layers forming "glue nodules," or insufficient glue to completely cover the bonding area, resulting in loose lens fixation and sealing failure. While existing technologies use centrifugation to remove air bubbles, this method is ineffective for high-viscosity glues and other materials. Centrifugation alone cannot completely remove deep, tiny air bubbles, potentially leaving stubborn bubbles with a diameter less than 0.1 mm, failing to meet the bubble-free requirements for high-precision glue application in goggles.

[0015] Compared with the prior art, the beneficial effects of this invention are as follows: This adhesive applicator for goggle production utilizes a fine needle on the outer side of the stirring shaft to initially puncture and remove air bubbles in the adhesive. Simultaneously, the stirring shaft drives the stirring frame to rotate, using vertical air-blade inside the stirring frame and horizontal air-blade outside to stir the adhesive while removing stubborn air bubbles a second time, thus improving the air-bubble removal effect. After adhesive application, the applicator head and unfolding plate close, providing a secondary seal for the adhesive and preventing residual adhesive inside the connecting tube, which could cause dripping and affect the amount of adhesive dispensed. By controlling the amount of adhesive dispensed, it avoids uncontrolled dispensing, excessively thick adhesive layers forming "adhesive nodules," or insufficient adhesive not completely covering the bonding area, leading to loose lens fixation and sealing failure. The specific details are as follows: 1. By incorporating an air bubble removal mechanism, not only can the glue be introduced into the storage tank via the feed pipe, but starting the stirring motor also drives the stirring shaft to rotate. The fine needles on the outer side of the stirring shaft can initially puncture and remove air bubbles in the glue. Simultaneously, the stirring shaft drives the stirring frame to rotate, using vertical air bubble cutters inside the frame and horizontal air bubble cutters on the outer side to stir the glue while removing stubborn air bubbles, thus improving the air bubble removal effect. The glue level inside the storage tank is higher than the top of the stirring frame, so external air is not stirred into the glue during the stirring frame's rotation, preventing an increase in air bubbles. Starting the centrifugal motor drives the centrifugal gear to rotate, utilizing the centrifugal gear and... The meshing connection between the centrifugal toothed rings allows them to rotate the glue storage tank. For fillerless glue, the rotation speed is 1000-3000 RPM for three minutes; for glue with fillers, the speed does not exceed 1000 RPM. Centrifugation completely removes suspended air bubbles from the glue. Because the glue's density is much greater than that of air bubbles, under centrifugal force, the denser glue is thrown to the side of the tank away from the center, while the less dense air bubbles, under the centrifugal "buoyancy," gather towards the central axis of rotation. The rotation allows the fine needles on the outside of the stirring shaft to puncture the bubbles, improving the initial bubble removal efficiency. Simultaneously, some stubborn air bubbles rise to the surface of the glue, triggering the lifting motor to drive the lifting screw. The rotating rod, utilizing the threaded connection between the lifting threaded bracket and the lifting threaded rod, causes the lifting threaded bracket to drive the lifting sliding rod and the lifting sliding plate to move up and down. The fine needle at the top of the lifting sliding plate punctures air bubbles on the adhesive surface, further improving the de-bubbling effect and preventing air pockets from forming within the adhesive layer during goggle application, thus avoiding interruptions in the application path and directly reducing the bonding strength between the lens and frame, potentially leading to air leakage. During goggle application, the electric telescopic rod moves the bottom fixing ring and the unfolding plate upwards, while the limiting sleeve slides at the bottom of the connecting tube. Under the action of the unfolding rotating rod, the unfolding sliding sleeve slides outside the unfolding sliding rod, simultaneously adjusting the adhesive application head. The adhesive slides relative to the unfolding plate, thus achieving uniform dispensing of the adhesive. The air bubble filter inside the unfolding plate can further filter out tiny air bubbles in the adhesive. Since the amount of adhesive applied to the edge of the goggles is less, the removal of air bubbles in the adhesive is improved to meet the bubble-free requirement of high-precision adhesive application for the goggles. After the adhesive is applied, the applicator and the unfolding plate are closed. The applicator and the unfolding plate can seal the adhesive a second time, preventing the adhesive from remaining inside the connecting tube and dripping, which would affect the amount of adhesive dispensed. By controlling the amount of adhesive dispensed, it is possible to avoid uncontrolled dispensing, excessively thick adhesive layers forming "adhesive nodules" in some areas, or insufficient adhesive to completely cover the bonding area, resulting in the lens not being firmly fixed and the seal failing. 2. By setting up an adjustment and fixing mechanism, not only can the goggles requiring adhesive be installed on the top of the goggle mounting block, but also, by rotating the clamping nut, the threaded connection between the clamping nut and the clamping threaded rod allows the clamping nut to move on the outside of the clamping threaded rod while simultaneously moving the clamping sliding plate and clamping block. The clamping block can hold and fix the goggles, improving the stability of the adhesive application. Starting the translation motor drives the translation threaded rod to rotate, causing the translation threaded sleeve to move the translation sliding plate, which moves the goggles to the bottom of the adhesive application head. Starting the vertical rotation motor drives the vertical rotation block to rotate vertically, while simultaneously starting the horizontal rotation motor drives the horizontal rotation shaft and the goggle mounting block to rotate horizontally, facilitating even adhesive application to the inside of the goggles and improving the adhesive application effect.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-4 , Figure 6The present invention provides a technical solution: a coating device for goggle production, comprising a bubble removal mechanism 1 and a lifting bracket 101 installed on the outside of the bubble removal mechanism 1. The bottom of the bubble removal mechanism 1 is provided with an adjustment and fixing mechanism 2, and the top of the adjustment and fixing mechanism 2 is provided with a goggle mounting block 214. The bubble removal mechanism 1 includes a glue storage tank 112, and a bellows-shaped protective cover 115 is fixedly installed on the top of the glue storage tank 112. A stirring motor 124 is fixedly installed on the inner side of the top of the glue storage tank 112. The output end of the stirring motor 124 is fixedly connected to a stirring rotating shaft 125. Side fine needles 126 are symmetrically installed on the outer side of the stirring rotating shaft 125. A stirring frame 127 is symmetrically installed on the side of the stirring rotating shaft 125 away from the side fine needles 126. Several vertical air ducts are fixedly installed inside each of the two stirring frames 127. Bubble blades 128 and several horizontal bubble blades 129 are fixedly installed on the outer sides of the two mixing frames 127. The glue is introduced into the glue storage tank 112 through the feed pipe 113. The mixing motor 124 is started to drive the mixing shaft 125 to rotate. The fine needles 126 on the outer side of the mixing shaft 125 can initially puncture and remove the air bubbles in the glue. At the same time, the mixing shaft 125 drives the mixing frame 127 to rotate. The vertical bubble blades 128 inside the mixing frame 127 and the horizontal bubble blades 129 on the outer side stir the glue and remove stubborn air bubbles in the glue a second time, thereby improving the effect of removing air bubbles from the glue. The height of the glue inside the glue storage tank 112 is higher than the top of the mixing frame 127. Therefore, when the mixing frame 127 rotates, it will not stir the outside air into the glue, thus preventing the increase of air bubbles.

[0020] Please see Figures 3-5A lifting fixing rod 116 is fixedly installed around the inside of the glue storage tank 112 near the bellows protective cover 115. A lifting top plate 117 is fixedly installed on the top of the lifting fixing rod 116. A lifting motor 118 is fixedly installed at the center of the top of the lifting top plate 117. A lifting threaded rod 119 is fixedly connected to the output end of the lifting motor 118. A lifting threaded bracket 120 is threadedly connected to the outer side of the lifting threaded rod 119. A lifting sliding rod 121 is fixedly installed around the bottom of the lifting threaded bracket 120. A lifting sliding plate 122 is fixedly installed. Both the lifting sliding plate 122 and the lifting sliding rod 121 are slidably connected to the glue storage tank 112. Several fine needles 123 are fixedly installed at the bottom of the lifting sliding plate 122. When the centrifugal motor 109 is started, it drives the centrifugal gear 110 to rotate. Utilizing the meshing connection between the centrifugal gear 110 and the centrifugal gear ring 111, the centrifugal gear ring 111 drives the glue storage tank 112 to rotate. For fillerless glue, the speed is 1000 to 3000 RPM for three minutes. For glue with filler, the speed does not exceed 1000 RPM. Through centrifugation... This method can completely remove suspended air bubbles in the glue. Since the density of the glue is much greater than that of the air bubbles, under centrifugal force, the denser glue will be thrown to the side of the bucket away from the center, while the air bubbles, which are much less dense than the glue, will gather towards the central axis of rotation under the influence of centrifugal buoyancy. The rotation allows the fine needles 126 on the outer side of the stirring shaft 125 to puncture the air bubbles, thus improving the efficiency of initial air bubble removal. Simultaneously, some stubborn air bubbles will rise to the surface of the glue, activating the lifting motor 118 to drive the lifting mechanism. The threaded rod 119 rotates, and by utilizing the threaded connection between the lifting threaded bracket 120 and the lifting threaded rod 119, the lifting threaded bracket 120 drives the lifting sliding rod 121 and the lifting sliding plate 122 to move up and down. The fine needle 123 at the top of the lifting sliding plate 122 punctures the air bubbles on the surface of the adhesive, further improving the effect of removing air bubbles from the adhesive. This prevents air from forming cavities inside the adhesive layer or interrupting the adhesive application path when applying adhesive to the goggles, which would directly reduce the bonding strength between the lens and the frame and easily lead to air leakage.

[0021] Please see Figures 2-8A feed pipe 113 is fixedly installed on one side of the top of the glue storage tank 112. A sealing cap 114 is threadedly connected to the top of the feed pipe 113.

A fixing plate 132 is fixedly installed at the bottom of the connecting pipe 131. A top fixing ring 133 is fixedly installed on the outside of the connecting pipe 131. Electric telescopic rods 134 are symmetrically installed at the bottom of the top fixing rings 133. Bottom fixing rings 135 are fixedly installed at the bottom of both electric telescopic rods 134. An unfolding plate 136 is fixedly installed inside the bottom fixing rings 135. A limit sleeve 137 is fixedly installed on the top outer side of the unfolding plate 136. The limit sleeve 137 is slidably connected to the connecting pipe 131. Next, an air bubble filter 138 is fixedly installed at the center of the interior of the unfolding tray 136. A telescopic sleeve 139 is fixedly installed on the top of the air bubble filter 138. The telescopic sleeve 139 is fixedly installed at the bottom of the fixed tray 132. symmetrical unfolding sliding rods 140 are installed inside the unfolding tray 136. An unfolding sliding sleeve 141 is slidably connected to the outer side of each of the two unfolding sliding rods 140. An unfolding spring 142 is fixedly installed on one side of the unfolding sliding sleeve 141 and is fixedly connected to the unfolding tray 136. An unfolding rotating rod 143 is rotatably connected to the top of the unfolding sliding sleeve 141 and is rotatably connected to the fixed tray 132. An adhesive applicator 144 is fixedly installed at the bottom of the unfolding sliding sleeve 141. The inner side of the top of the adhesive applicator 144 is fixed... An unfolding plate 145 is installed. A lifting cylinder 102 is fixedly installed on the inner top of the lifting support 101. A longitudinal support 103 is fixedly installed on the bottom of the lifting cylinder 102. The longitudinal support 103 is slidably connected to the lifting support 101. A longitudinal motor 104 is fixedly installed at the end of the longitudinal support 103. A longitudinal threaded rod 105 is fixedly connected to the output end of the longitudinal motor 104. A longitudinal limiting threaded sleeve 106 is threadedly connected to the outer side of the longitudinal threaded rod 105. A heating ring 107 is fixedly installed on one side of the longitudinal limiting threaded sleeve 106. A gear protective cover 108 is fixedly installed on the top of the heating ring 107. A centrifugal motor 109 is fixedly installed on one side of the top of the gear protective cover 108. A centrifugal gear 110 is fixedly connected to the output end of the centrifugal motor 109. A centrifugal gear 110 is meshed with a centrifugal gear ring 111 on one side. A glue storage tank 112 is fixedly installed inside the centrifugal gear ring 111. When applying glue to the goggles, an electric telescopic rod 134 drives the bottom fixing ring 135 and the unfolding plate 136 to move upwards. Simultaneously, a limiting sleeve 137 slides at the bottom of the connecting pipe 131. Under the action of the unfolding rotating rod 143, the unfolding sliding sleeve 141 slides outside the unfolding sliding rod 140, while simultaneously adjusting the relative sliding of the glue application head 144 and the unfolding plate 145, thereby achieving uniform glue dispensing. The bubble filter 138 inside the unfolding plate 136 can further filter out tiny air bubbles in the glue. Since the amount of glue applied to the edge of the goggles is relatively small, improving the removal of air bubbles in the glue is crucial.This meets the bubble-free requirement for high-precision adhesive application on goggles. After adhesive application, the applicator head 144 and the unfolding plate 145 close, providing a secondary seal for the adhesive. This prevents residual adhesive inside the connecting tube 131 from dripping and affecting the amount of adhesive dispensed. By controlling the amount of adhesive dispensed, it avoids uncontrolled dispensing, excessively thick adhesive layers forming "adhesive nodules," or insufficient adhesive covering the bonding area, which could lead to loose lens fixation and seal failure.

[0022] Please see Figures 1-2 , Figures 7-11The adjusting and fixing mechanism 2 includes an adhesive application worktable 201, which is fixedly connected to a lifting bracket 101. A translation base 202 is fixedly installed on the top of the adhesive application worktable 201, and a translation motor 203 is fixedly installed at the end of the translation base 202. A translation threaded rod 204 is fixedly connected to the output end of the translation motor 203, and a translation threaded sleeve 205 is threadedly connected to the outer side of the translation threaded rod 204.

A vertical rotation block 211 is fixedly connected to the output end of the vertical rotation motor 210. A horizontal rotation motor 212 is fixedly installed on the inner side of the vertical rotation block 211.

A clamping block 219 is fixedly installed on one side of the top of the clamping sliding plate 218. The clamping sliding plate 218 is slidably connected to the clamping threaded rod 215 and the clamping limit rod 216. The goggles that need to be coated with adhesive are installed on the top of the goggle mounting block 214. By rotating the clamping nut 217, the threaded connection between the clamping nut 217 and the clamping threaded rod 215 is utilized, causing the clamping nut 217 to move outward on the clamping threaded rod 215 while simultaneously driving the clamping block 219. The sliding plate 218 and clamping block 219 move together, and the clamping block 219 can hold and fix the goggles, improving the stability of the glue application on the goggles. The translation motor 203 is started to drive the translation threaded rod 204 to rotate, so that the translation threaded sleeve 205 drives the translation sliding plate 208 to move, which can move the goggles to the bottom of the glue application head 144. The vertical rotation motor 210 is started to drive the vertical rotation block 211 to rotate vertically, and at the same time the horizontal rotation motor 212 is started to drive the horizontal rotation shaft 213 and the goggles mounting block 214 to rotate horizontally, which facilitates the uniform application of glue to the inside of the goggles and improves the glue application effect of the goggles.

[0023] Working principle: Before using this type of adhesive coating device for goggle production, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 11As shown, firstly, the glue is introduced into the glue storage tank 112 through the feed pipe 113. The stirring motor 124 is started, driving the stirring shaft 125 to rotate. The fine needles 126 on the outer side of the stirring shaft 125 can initially puncture and remove air bubbles in the glue. Simultaneously, the stirring shaft 125 drives the stirring frame 127 to rotate. The vertical air blasting blades 128 inside the stirring frame 127 and the horizontal air blasting blades 129 on the outer side of the frame stir the glue while simultaneously removing stubborn air bubbles, thereby improving the glue's cleaning effect. The effect of bubble formation is that the height of the glue inside the storage tank 112 is higher than the top of the mixing frame 127. Therefore, when the mixing frame 127 rotates, it will not stir outside air into the glue, thus preventing an increase in bubbles. The centrifugal motor 109 is started, driving the centrifugal gear 110 to rotate. Utilizing the meshing connection between the centrifugal gear 110 and the centrifugal gear ring 111, the centrifugal gear ring 111 drives the storage tank 112 to rotate. For unfilled glue, the rotation speed is 1000 to 3000 RPM for three minutes; for glue with fillers, the speed does not exceed 1000 RPM. This is achieved through centrifugation. This method can completely remove suspended air bubbles in the glue. Since the density of the glue is much greater than that of the air bubbles, under centrifugal force, the denser glue will be thrown to the side of the bucket away from the center, while the air bubbles, which are much less dense, will gather towards the central axis of rotation under the influence of centrifugal buoyancy. The rotation allows the fine needles 126 on the outer side of the stirring shaft 125 to puncture the air bubbles, thus improving the efficiency of initial air bubble removal. Simultaneously, some stubborn air bubbles will rise to the surface of the glue, activating the lifting motor 118 to lift... The threaded rod 119 rotates, and by utilizing the threaded connection between the lifting threaded bracket 120 and the lifting threaded rod 119, the lifting threaded bracket 120 drives the lifting sliding rod 121 and the lifting sliding plate 122 to move up and down. The fine needle 123 at the top of the lifting sliding plate 122 punctures the air bubbles on the surface of the adhesive, further improving the effect of removing air bubbles from the adhesive. This prevents air from forming cavities inside the adhesive layer or interrupting the adhesive application path when applying adhesive to the goggles, which would directly reduce the bonding strength between the lens and the frame and easily lead to air leakage.

[0024] Next, the goggles that need to be coated with adhesive are installed on the top of the goggle mounting block 214. By rotating the clamping nut 217, the clamping nut 217 is connected to the clamping threaded rod 215. This allows the clamping nut 217 to move on the outside of the clamping threaded rod 215, while simultaneously moving the clamping sliding plate 218 and the clamping block 219. The clamping block 219 can hold and fix the goggles, improving the stability of the adhesive coating process. The translation motor 203 is started to rotate the translation threaded rod 204, causing the translation threaded sleeve 205 to move the translation sliding plate 208. This moves the goggles to the bottom of the adhesive application head 144. The vertical rotation motor 210 is started to rotate the vertical rotation block 211 vertically, while the horizontal rotation motor 212 is started to rotate the horizontal rotation shaft 213 and the goggle mounting block 214 horizontally. This facilitates even coating of adhesive on the inside of the goggles and improves the coating effect.

[0025] Finally, when applying adhesive to the goggles, the lifting cylinder 102 is activated to move the longitudinal support 103 up and down. Simultaneously, the longitudinal motor 104 is activated to rotate the longitudinal threaded rod 105, causing the longitudinal limiting threaded sleeve 106 to move the heating ring 107 and the adhesive storage tank 112 longitudinally. The heating ring 107 heats the adhesive, controlling the temperature between 35 and 40 degrees Celsius, reducing the adhesive viscosity and allowing air bubbles to rise naturally, thus improving the de-bubbling effect. The electric telescopic rod 134 moves the bottom fixing ring 135 and the unfolding plate 136 upwards, while the limiting sleeve 137 slides at the bottom of the connecting pipe 131. Under the action of the unfolding rotating rod 143, the unfolding sliding sleeve 141 slides outside the unfolding sliding rod 140, simultaneously adjusting the adhesive application head 144 and the unfolding plate. The relative sliding of 145 allows for uniform glue application. The bubble filter 138 inside the unfolding plate 136 can further filter out tiny air bubbles in the glue. Since the amount of glue applied to the edge of the goggles is relatively small, improving the removal of air bubbles in the glue can meet the bubble-free requirement for high-precision glue application of the goggles. After the glue application is completed, the glue applicator 144 and the unfolding plate 145 are closed. The glue applicator 144 and the unfolding plate 145 can perform a secondary sealing of the glue, preventing glue residue inside the connecting tube 131 from dripping and affecting the amount of glue applied. By controlling the amount of glue applied, it is possible to avoid uncontrolled glue application, excessive glue layer accumulation forming "glue nodules" in some areas, or insufficient glue to completely cover the bonding area, resulting in the lens not being firmly fixed and the seal failing.
