Description

Technical Field

[0001] The invention relates to the technical field of lamps, and more particularly to a precision structural part of an explosion-proof lamp and a gluing device for gluing the same. Background Art

[0002] Explosion-proof lamps refer to lamps used in hazardous places where flammable gases and dust exist. They can prevent arcs, sparks and high temperatures that may be generated inside the lamp from igniting flammable gases and dust in the surrounding environment, thereby meeting explosion-proof requirements. At present, when producing linear explosion-proof lamps, the lamp tubes need to be sealed. Usually, the sealing method is to manually apply glue to the slots opened on the lamp holder, and then the lamp shell is stuck in the slots to prevent water from entering the lamp holder and damaging the lamp tube. However, the manual gluing method is not only inefficient, but also has the problem of uneven gluing, resulting in poor product performance.

[0003] The Chinese patent with publication number CN112555700B discloses a sealing process for LED bulb production. A downward upright glue coating pen is fixedly installed on at least two sliders, so that each time the glue coating pen rack moves to the left, the sealing glue is applied to the multiple card slots at the top of the lamp holder, thereby improving the coating efficiency. The lifting height is controlled by an electric push rod, so that the glue coating pen can more accurately apply the sealing glue to the card slots at the top of the lamp holder, thereby improving the uniformity of the sealing glue application. The glue coating device is used to control the lifting height of the glue coating pen when the glue coating pen retreats upward. When the glue pen is returned, it is prevented from adhering upwards and forming wire drawing. After the glue pen is returned, the cutting piece rotates at the bottom of the glue pen to cut off the glue wire drawing from the air to prevent the glue wire that is too long from adhering to the bottom of the glue pen. Although the sealing device improves the sealing efficiency, when the glue pen applies glue to the card slot, it cannot ensure that the inner wall of the card slot is evenly stained with glue, resulting in a gap when the lampshade is connected to the card slot, and the sealing effect is poor. At the same time, when cutting the glue by cutting the glue piece, there will still be glue wire drawing, and it cannot ensure that the glue is thoroughly applied, and the practicality is low.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0036] Embodiment 1

[0037] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0038] like Figure 1 and Figure 2As shown, a precision structure of an explosion-proof lamp includes a profile body 1, a slot 2 for installing a lampshade is provided on the profile body 1, a placement slot 3 is provided below the slot 2, flameproof threads 4 are provided on both sides of the placement slot 3, an installation slot 5 is provided below the placement slot 3, a thin wall 6 and a thick wall 7 are provided on both sides of the installation slot 5, and the flameproof threads 4 on both sides of the placement slot 3 are used to connect wire connectors.

[0039] It should be emphasized that if Figure 2 As shown, the thickness of the thick wall 7 is between 2.5cm and 3cm, and the thickness of the thin wall 6 is between 1.5cm and 2cm. The thick wall 7 is the explosion-proof side of the profile body 1. The explosion-proof effect can be improved by the inner wall structure of different thicknesses and the explosion-proof thread 4, and the weight of the installation groove 5 is reduced, thereby improving the practicality of the profile body 1.

[0040] In addition, if Figure 1 As shown, the profile body 1 is made of aluminum alloy, which reduces the overall weight of the profile body 1 , improves the overall strength, and prolongs the service life of the profile body 1 .

[0041] Embodiment 2

[0042] like Figures 3 to 10 As shown, a glue coating device for precision structural parts of explosion-proof lamps includes a base 8, a slide rail 9 arranged on the base 8, and a tray 10 slidably arranged on the slide rail 9 for carrying a profile body 1. A driving assembly 11 and a glue coating assembly 12 driven by the driving assembly 11 are symmetrically arranged on the base 8. A single group of glue coating assemblies 12 include a glue coating cylinder 121 and a glue box 122. A glue coating assembly 13 is arranged on the glue coating cylinder 121. The glue coating assembly 13 includes a plurality of glue coating rollers 131. A rotating assembly 14 is arranged between the glue coating roller 131 and the glue coating cylinder 121. A scraper plate 15 is arranged on one side of the glue coating roller 131. A glue suction assembly is arranged on the scraper plate 15. 16, the glue coating component 12 is used to apply glue to the slot 2 of the profile body 1 and drive the glue coating cylinder 121 to rotate through the driving component 11, the glue spreading component 13 is used to drive the glue spreading roller 131 to rotate in the slot 2 while the glue coating cylinder 121 rotates to spread the glue, the glue suction component 16 is used to suck the excess glue on the glue spreading roller 131 into the glue box 122 through the scraper plate 15 with the cooperation of the rotating component 14, wherein the slide rail 9 is provided with a driver, which can drive the tray 10 for transmission, the profile body 1 is placed on the tray 10 and transmitted through the glue coating cylinder 121 for glue coating, and a heating wire is provided in the glue coating cylinder 121 to prevent the glue from drying.

[0043] In addition, if Figure 4As shown, the single-group driving assembly 11 includes a support plate 111 fixedly arranged on the base 8, a fixed rod 112 fixedly arranged on the support plate 111, a rotating shaft 113 rotatably arranged on the fixed rod 112, and a motor 114 fixedly arranged on the support plate 111. The output shaft of the motor 114 is connected to the rotating shaft 113. When in use, after the profile body 1 is transmitted to the glue coating cylinder 121, the motor 114 drives the rotating shaft 113 to rotate in the fixed rod 112, thereby driving the glue coating cylinder 121 to rotate, thereby improving the fluidity of the glue. Combined with the heating wire, it can be ensured that the glue is always in a flowing state.

[0044] It should be further explained that if Figures 4 to 8 As shown, the single-group glue coating assembly 12 also includes a glue coating head 123 fixedly arranged on the fixed rod 112, an electric valve 124 arranged on the glue coating head 123, and a rubber hose 125 fixedly arranged on the glue box 122. The glue coating cylinder 121 is rotatably arranged on the fixed rod 112 and is connected to the glue coating head 123. The glue box 122 is fixedly arranged on the support plate 111. A belt is arranged between the rotating shaft 113 and the glue coating cylinder 121. The rubber hose 125 is rotatably matched with the glue coating cylinder 121. The electric valve 124 is arranged on the glue coating head 123. It is electrically connected to an external switch, and the electronically controlled valve 124 can allow glue to flow out from the glue coating head 123 after it is turned on. During use, when the glue coating head 123 is located on one side of the card slot 2, the electronically controlled valve 124 is started, driving the glue to flow from the glue coating head 123 to the inner wall of the card slot 2. The pallet 10 is always transported with the profile body 1. During the transportation process, the glue coating head 123 continuously discharges glue to coat the inner wall of the card slot 2, thereby solving the problem of slow efficiency of manual gluing. The glue in the glue box 122 can be replenished from the outside.

[0045] It should be emphasized that if Figure 7 and Figure 8 As shown, the single-group glue spreading component 13 also includes connecting rods 132 fixedly arranged on both sides of the glue coating cylinder 121, and the glue spreading roller 131 is rotatably arranged on the connecting rods 132. When in use, the rotating shaft 113 drives the glue coating cylinder 121 to rotate through a belt, and the glue coating cylinder 121 drives the glue spreading roller 131 to rotate in the card slot 2. The glue is evenly spread on the inner wall of the card slot 2 through the glue spreading roller 131 to ensure that the inner wall of the card slot 2 is evenly stained with glue.

[0046] It is worth mentioning that Figure 8As shown, the single-group rotating component 14 includes an active tooth 141 fixedly arranged on the fixed rod 112, and a passive tooth 142 fixedly arranged on the glue-distributing roller 131. The active tooth 141 is meshed with the passive tooth 142, and the glue-distributing cylinder 121 is rotated and matched with the active tooth 141. When in use, when the glue-distributing cylinder 121 rotates, it drives the glue-distributing roller 131 and the passive tooth 142 to revolve. During the revolution, the passive tooth 142 is meshed with the active tooth 141, so that the glue-distributing roller 131 can rotate while distributing glue. During the rotation, the surface of the glue-distributing roller 131 is scraped by the scraper plate 15, so that the excess glue in the slot 2 is scraped off, and the glue is evenly applied in the slot 2, so as to ensure that the glue in the slot 2 of each profile body 1 is consistent, and at the same time, it is ensured that there is no residual glue on the surface of the glue-distributing roller 131 when the glue is distributed for the next time, so as to prevent the glue from drawing.

[0047] Further, such as Fig. 9 and Fig.10 As shown, the single glue suction assembly 16 includes a glue suction hole 161 opened on the scraper 15, a plurality of channels 162 opened on the inner wall of the glue coating cylinder 121, a fixed sleeve 163 fixedly arranged on the glue tube 125, a glue suction tube 164 fixedly arranged between the fixed sleeve 163 and the glue box 122, and a glue pump 165 fixedly arranged on the glue suction tube 164. One end of the scraper 15 is fixedly arranged on the glue coating cylinder 121, and the other end is matched with the glue leveling roller 131. The scraper 15 is connected to the channel 162, and the glue coating cylinder 121 is connected to the fixed sleeve 163. The sleeve 163 is rotated to cooperate, wherein a one-way valve is also provided on the glue suction tube 164, so that glue can only enter but not exit the glue box 122. After the glue pump 165 is turned on, the glue suction hole 161 generates suction to adsorb the glue. When in use, when the scraper 15 is scraping glue, the glue pump 165 is turned on at the same time, so that the scraper 15 can scrape the glue from the glue suction hole 161 through the channel 162, the fixed sleeve 163, and the glue suction tube 164 to the glue box 122, so that excess glue can re-enter the glue box 122, thereby achieving the effect of reusing the glue.

[0048] In addition, if Fig. 9 As shown, the scraper 15 is made of hard rubber material to prevent damage to the surface of the glue roller 131.

[0049] Working process

[0050] After the profile body 1 is transferred to the glue coating cylinder 121, the motor 114 drives the rotating shaft 113 to rotate in the fixed rod 112, thereby driving the glue coating cylinder 121 to rotate, and the electric control valve 124 is started, driving the glue to flow from the glue coating head 123 to the inner wall of the card slot 2, and the glue coating cylinder 121 drives the glue leveling roller 131 to revolve and level the glue while driving the active gear 141 and the passive gear 142 to engage, so that the glue leveling roller 131 rotates, and the glue is evenly applied to the inner wall of the card slot 2 by the glue leveling roller 131. While ensuring that the inner wall of the card slot 2 is evenly stained with glue, the surface of the glue leveling roller 131 is scraped with glue by the scraper plate 15. After the glue pump 165 is turned on, the glue scraped off by the scraper plate 15 reaches the glue box 122 from the glue suction hole 161 through the channel 162, the fixed sleeve 163, and the glue suction tube 164, so that the excess glue re-enters the glue box 122, so as to achieve the effect of reusing the glue.
