DETAILED DESCRIPTION

[0018] The technical solutions of the present application will be described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0019] Embodiment one Please refer to Figures 1-10 The present application provides a technical solution: a UV glue automatic dispensing device, comprising a main machine 100, a workpiece 102 arranged above the main machine 100, a Z axis 105, a lifting plate 109 slidingly arranged on the Z axis 105, and a dispensing head 104 fixed on the front of the lifting plate 109. The dispensing head 104 is connected to an external glue storage tank through a connecting pipeline, the inside of the glue storage tank is vacuumized, the air pressure in the glue storage tank is reduced, the UV glue is in a vacuum environment, the dissolved gas in the glue solution is more easily escaped due to the reduced air pressure, thereby reducing the generation of air bubbles during dispensing, and at the same time, the vacuum environment can weaken the surface tension and adhesion of the glue solution, so that the glue solution can more smoothly separate from the bottom of the dispensing head 104 after dispensing, avoiding the phenomenon of glue hanging. The bottom of the dispensing head 104 is provided with a preforming mechanism, which comprises: A pre-curing assembly, comprising a sleeve 201 fixedly sleeved on the outside of the bottom of the dispensing head 104 and a ring frame 200 sleeved on the outside of the sleeve 201. The bottom of the ring frame 200 is respectively fixedly provided with a light blocking ring 206 and a plurality of auxiliary curing lamps 202. The light blocking ring 206 can prevent ultraviolet light from irradiating the area below the dispensing head 104, avoiding irradiation to the glue solution just coming out below the dispensing head 104, facilitating the scraping of the glue solution by the scraping strip 205 before irradiation and curing. The auxiliary curing lamps 202 are used for preliminary curing of the UV glue coated on the inclined surface of 102. The inner part of the ring frame 200 is screwed with a locking screw 203, which can be adjusted according to the needs in use. When adjusting, the locking screw 203 is loosened by rotating outward, and the working end of the locking screw 203 is then separated from the outer wall of the sleeve 201. Then the ring frame 200 can be moved upward or downward, driving the multiple groups of auxiliary curing lamps 202 on the ring frame 200 to follow. Then the locking screw 203 is tightened by rotating towards the sleeve 201, and the working end of the locking screw 203 contacts the outer wall of the sleeve 201, so that the ring frame 200 can be fixed, and the distance between the auxiliary curing lamps 202 and the workpiece 102 can be adjusted. The light irradiation distance and intensity of the auxiliary curing lamps 202 irradiating the UV glue on the workpiece after dispensing can be conveniently adjusted (the irradiation intensity of the auxiliary curing lamps 202 on the glue increases when they are close to the glue, and the irradiation intensity of the auxiliary curing lamps 202 on the glue decreases when they are away from the glue). The working end of the locking screw 203 extends to the surface of the sleeve 201, which is used to adjust the distance between the auxiliary curing lamps 202 and the workpiece 102.

[0020] Example Two Based on Example One, see Figures 1-9 The preforming mechanism further includes a scraping assembly, which includes a scraping strip 205 arranged below the dispensing head 104 and multiple vertical rods 212 arranged on the inner wall of the scraping strip 205. The top view of the scraping strip 205 is annular, and the bottom of the vertical rod 212 is arranged with lower balls 215. The dispensing head 104 is arranged with an upper seat 213, and the top of the upper seat 213 is fixedly arranged with a conical column, which can facilitate the glue inside the dispensing head 104 to pass through the upper seat 213. The bottom of the upper seat 213 is arranged with upper balls 214, which are in a liquid state with bottom viscosity and no particles inside. The upper balls 214 and the lower balls 215 are not worn during the rolling process, and multiple extension rods are fixedly arranged between the upper balls 214 and the scraping strip 205. The outer side of the dispensing head 104 is arranged with a ring plate 211, and the top outer wall of the ring plate 211 is fixedly arranged with multiple lower discs 210. The outer part of the sleeve 201 is fixedly arranged with an upper ring 207, and the upper ring 207 is fixedly arranged with multiple L-shaped plates 208, and the L-shaped plates 208 are fixedly arranged with connecting springs 209 between the lower discs 210.

[0021] In summary, when the lifting plate 109 is lowered to drive the dispensing head 104 to dispense glue on the workpiece 102 with an inclined surface placed on the slide 108, the preforming mechanism is lowered along with the dispensing head 104. Then the lower balls 215 at the bottom of the vertical rods 212 first contact the workpiece 102 with an inclined surface. Since the upper surface of the workpiece 102 has an inclined surface, the preforming mechanism continues to descend. According to the angle of the inclined surface, the vertical rods 212, the outer ring 402, and the ring plate 211 adaptively tilt around the upper balls 214 as the center. Then the lower balls 215 at the bottom of the vertical rods 212 contact the inclined surface of the workpiece 102. At this time, the scraping strip 205 is parallel to the inclined surface of the workpiece 102 (the distance between the scraping strip 205 and the inclined surface of the workpiece 102 is the thickness of the UV glue after scraping). At this time, the connecting springs 209 on the ring plate 211 in the inclined direction are stretched (when the dispensing is completed or the dispensing on the planar workpiece 102 starts, the stretched connecting springs 209 reset to help the inclined ring plate 211 and the scraping strip 205 return to the original position). Then the multiple auxiliary curing lamps 202 at the bottom of the ring frame 200 on the preforming mechanism are located above the workpiece 102. Then when the dispensing head 104 moves to dispense glue on the workpiece 102, the UV glue is coated on the inclined surface of the workpiece 102 from the bottom of the dispensing head 104. Then the scraping strip 205 moves along with the movement of the dispensing head 104. Then the scraping strip 205 scrapes the UV glue on the inclined surface to make the thickness of the UV glue on the inclined surface of the workpiece 102 uniform. Then the UV light emitted by the auxiliary curing lamp 202 below moves rapidly to the UV glue coated and scraped on the surface of the workpiece 102. The surface layer of the glue is cured first (the outer surface layer of the glue is preformed and cured), forming a solid film, while the inside remains liquid. The cured surface layer has a certain strength, which can wrap the liquid UV glue inside to avoid the flow phenomenon. The dispensing in the previous process, the scraping and light curing in the subsequent process reduce the flow phenomenon of the UV glue coated on the inclined surface of the workpiece 102. Moreover, the slide 108 can avoid the flow phenomenon of the workpiece 102 caused by vibration during the movement of the workpiece 102 on the Y-axis 101. Thus, the area of the coated glue is prevented from exceeding the original design range. When the dispensing is completed, the workpiece 102 is moved below the main curing lamp 103 to completely cure the glue.

[0022] Example Three Based on Example Two, please refer to Figures 4-9 The outer side of the ring plate 211 is provided with an adjusting part for adjusting the height of the scraping strip 205. The adjusting piece comprises an outer ring 402 fixed at the top of the vertical rod 212, and a mounting bracket 400 is fixedly arranged at the top of the outer ring 402, and the inner part of the ring plate 211 is provided with a lifting groove, and the mounting bracket 400 can move up and down in the lifting groove; The inner part of the mounting bracket 400 is threadedly connected with a mounting screw rod 401, and the working end of the mounting screw rod 401 extends to the surface of the ring plate 211; The outer wall of the upper seat 213 is fixedly provided with three groups of sliding plates 403, the inner wall of the dispensing head 104 is provided with three groups of vertical grooves 404, the end part of the sliding plate 403 penetrates into the inner part of the vertical groove 404, and the end part of the sliding plate 403 is fixedly connected with the inner wall of the vertical groove 404.

[0023] In summary, the distance between the scraping strip 205 and the workpiece 102 can be adjusted in use, so as to adjust the thickness of the UV glue coated on the surface of the workpiece 102 by the scraping strip 205. When adjusting, the mounting screw rod 401 is rotated and loosened to the outside, at this time the working end of the mounting screw rod 401 is no longer in contact with the outer wall of the ring plate 211, then the mounting bracket 400 is moved upward or downward, driving the outer ring 402 and the plurality of vertical rods 212 located at the bottom of the outer ring 402 to move upward or downward. If the vertical rod 212 moves upward, the distance between the lower ball 215 at the bottom of the vertical rod 212 and the scraping strip 205 decreases. At this time, in use, after the lower ball 215 contacts the workpiece 102, the distance between the workpiece 102 and the scraping strip 205 decreases, and at this time the thickness of the glue solution scraped on the surface of the workpiece 102 by the scraping strip 205 decreases, and vice versa. When the adjustment is completed, the mounting screw rod 401 is rotated and tightened to the dispensing head 104, and then the working end of the mounting screw rod 401 contacts and clamps the outer wall of the ring plate 211, so that the scraping thickness of the glue solution on the workpiece 102 by the scraping strip 205 can be adjusted.

[0024] Embodiment four Based on the embodiment three, see Figures 1-5 The ring frame 200 is provided with a cleaning piece for cleaning some dust on the surface of the workpiece 102, and the cleaning piece comprises a plurality of blowing pipes 303 embedded and mounted on the ring frame 200, and the outer part of the blowing pipe 303 is provided with two groups of inclined grooves 307 for blowing the dust attached to the outer surface of the auxiliary curing lamp 202; The outer part of the blowing pipe 303 is provided with a one-way valve 302, the top of the ring frame 200 is fixedly provided with a hollow fixing ring 204, and the top of the blowing pipe 303 is communicated with the hollow fixing ring 204; The two sides of the Z-axis 105 are respectively fixedly provided with a blower 300 and a negative pressure pump 306, and the hollow fixing ring 204 is fixedly provided with a telescopic hose between the blower 300 and the negative pressure pump 306. The outer part of the telescopic hose is respectively provided with an electric valve one 304 and an electric valve two 305, and the top of the negative pressure pump 306 is fixedly provided with an extension pipe.

[0025] In summary, when the workpiece 102 is placed on the slide 108 before dispensing, if dust is attached to the position to be coated on the surface of the workpiece 102, the electric valve one 304 on the left side of the hollow fixing ring 204 is closed, and then the electric valve two 305 on the right side is opened. Then the dispensing head 104 is lowered to the appropriate height position, which drives the corresponding ring holder 200 and the blowpipe 303 on the ring holder 200 to follow. Then the negative pressure pump 306 is started, and the negative pressure generated by the negative pressure pump 306 causes the bottom of the blowpipe 303 and the plurality of inclined grooves 307 opened on the outer surface to generate negative pressure, so that the area above the workpiece 102 forms a negative pressure state, and some dust attached to the upper surface of the workpiece 102 is sucked into the blowpipe 303. Then it enters the negative pressure pump 306 through the hollow fixing ring 204 and the flexible hose on the right side of the hollow fixing ring 204, and then connects the dust purifier through the extension pipe at the top of the negative pressure pump 306. The negative pressure generated by the negative pressure device in the dust purifier sucks the dust in the negative pressure pump 306 into the dust purifier for purification treatment. When the dust cleaning is completed, the ring holder 200 rises to the original position along with the dispensing head 104. After being used for a long time, dust is attached to the outer surface of the auxiliary curing lamp 202, which covers the outer surface of the auxiliary curing lamp 202, resulting in a decrease in the light intensity of the auxiliary curing lamp 202 irradiating the glue liquid. At this time, the electric valve two 305 on the flexible hose on the right side of the hollow fixing ring 204 is closed, the electric valve one 304 on the left side is opened, and then the air blower 300 is started. The air blower 300 generates strong wind to be delivered to the blowpipe 303. At this time, the one-way valve 302 in the blowpipe 303 is closed, and then the strong wind in the blowpipe 303 blows to the outer wall of the auxiliary curing lamp 202 through the plurality of inclined grooves 307, blows off the dust attached to the outer wall, and keeps the cleanliness of the outer surface of the auxiliary curing lamp 202.

[0026] In the embodiment, the top of the main machine 100 is provided with the Y-axis 101, the slide 108 is slidably arranged on the Y-axis 101, and the workpiece 102 is located on the top of the slide 108.

[0027] In the embodiment, the two side surfaces of the main machine 100 are fixedly provided with the side frames 107, the top of the side frame 107 is provided with the X-axis 106, the Z-axis 105 is slidably arranged on the X-axis 106, the lifting plate 109 is slidably arranged on the Z-axis 105, and the two groups of side frames 107 are fixedly provided with the main curing lamp 103.
