Description

Technical Field

[0001] The present invention relates to the technical field of dispensing, and particularly to a dispensing device for LED lamp processing. Background Art

[0002] In the production of LED lamps, sealant is used at the connection of the lamp body housing to seal the lamp body. Commonly used sealants include silicone sealant, which has good flexibility and weather resistance. Silicone sealant can maintain good sealing performance within the temperature range of -50°C to 200°C, effectively preventing rain, sand, etc. from entering the interior of the lamp. The sealant can also enhance the mechanical strength of the lamp body, resist external impacts and pressures to a certain extent, and maintain the integrity of the lamp body structure.

[0003] In this regard, the patent of CN118904650B discloses an LED lamp dispenser and dispensing process for preventing glue leakage, including a moving unit and a dispensing head; a glue outlet groove is vertically opened at the lower part of the dispensing head, and glue flows out from the glue outlet groove. A blocking block is slidably arranged in the dispensing head along the extending direction of the glue outlet groove. A pressing frame that reciprocates vertically is arranged at the upper part of the dispensing head. The moving directions of the blocking block and the pressing frame in the vertical direction are always opposite. A storage cavity for supplying glue to the glue outlet groove is arranged at the lower part of the pressing frame. The pressing frame has a highest position and a lowest position in its vertical moving stroke. When the pressing frame is at the highest position, the blocking block blocks the glue outlet groove, and the pressing frame does not generate pressure on the storage cavity. When the pressing frame is at the lowest position, the pressing frame generates a squeezing pressure on the storage cavity, and the blocking block completely releases the glue outlet groove. The present invention ensures that no glue leakage occurs when the dispensing head dispenses glue.

[0004] The above-mentioned dispensing device for LED lamp processing uses a blocking block that moves up and down to block the glue at the needle tip, and cooperates with a through hole arranged on the side to absorb the residual glue at the needle tip. There is a certain wear due to the multiple up and down reciprocating movements of the blocking block, and there is a certain gap between it and the inner wall of the needle barrel. For some glues with a thinner texture, it is still possible for the glue to seep downward from the gap. And after the through hole sucks away the glue at its end, there is still a thin layer of glue remaining on the inner wall of the needle tip. This layer of glue is exposed to the air and is relatively thin, and it is very easy to solidify and dry. Over time, the glue that dries layer by layer on the inner wall of the needle tip will reduce the inner diameter of the needle tip, block the needle, and cause the problem of unstable glue output.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] To further understand the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings.

[0034] Combined with Figures 1 - 10, A dispensing device for processing LED lamps of the present invention includes a dispensing device bottom plate 1. A transmission mechanism 2 is erected on the top plate of the dispensing device bottom plate 1. The output end of the transmission mechanism 2 is fixedly connected to a dispensing cylinder 3. The bottom of the dispensing cylinder 3 is fixedly connected to a dispensing needle 4. A glue anti-dripping component 5 is installed inside the dispensing needle 4. The glue anti-dripping component 5 includes a first flexible connecting piece 501, and the first flexible connecting piece 501 is fixedly connected to the inner wall of the dispensing needle 4. The bottom of the first flexible connecting piece 501 is fixedly connected to a telescopic outer plate 502, and a telescopic inner plate 503 is sleeved inside the telescopic outer plate 502. A rectangular opening 504 is opened inside the telescopic inner plate 503, and a flexible top piece 505 is fixedly connected inside the rectangular opening 504. On the side of the inner wall of the dispensing needle 4 away from the first flexible connecting piece 501, a second flexible connecting piece 506 is fixedly connected. The bottom of the second flexible connecting piece 506 is fixedly connected to a first bending piece 507, and the bottom of the first bending piece 507 is fixedly connected to a third flexible connecting piece 508. The bottom of the third flexible connecting piece 508 is fixedly connected to a second bending piece 509. The end of the second bending piece 509 is in clearance fit with a limiting strip 510, and the limiting strip 510 is fixedly connected to the inner wall of the dispensing needle 4. A first spring 511 is further arranged inside the telescopic outer plate 502. The top end of the first spring 511 is fixedly connected to the telescopic outer plate 502, and the bottom end of the first spring 511 is fixedly connected to the telescopic inner plate 503. The telescopic inner plate 503 is slidably connected to the telescopic outer plate 502. When the bottom side of the telescopic inner plate 503 just rotates to the other side of the dispensing needle 4, the total length of the telescopic outer plate 502 and the telescopic inner plate 503 is such that it just can contact the bottom end of the second bending piece 509. When it gradually rotates upward, the first spring 511 can be compressed to adaptively adjust its total length.

[0035] When the driven airbag 604 is in the inflated state, the driven airbag 604 presses against the telescopic outer plate 502 and the telescopic inner plate 503 from the side and rotates upward obliquely. When rotating to a certain extent, the bottom side of the telescopic inner plate 503 contacts the bottom edge of the second bending piece 509. During the process of gradually rotating upward obliquely, the telescopic inner plate 503 presses against the second bending piece 509 and gradually moves upward, causing the second bending piece 509 and the first bending piece 507 to form a bend. During the process of the telescopic inner plate 503 gradually rotating upward obliquely and the second bending piece 509 gradually bending, a space in the shape of an upward-opening V is formed between the flexible top piece 505 and the second bending piece 509, and the opening of this V-shaped gradually shrinks, gradually squeezing the glue inside it back into the interior of the dispensing needle 4. When the bottom end of the second bending piece 509 gradually moves upward and contacts the limit strip 510, blocked by the limit strip 510, the second bending piece 509 will not continue to bend. At the same time, the driven airbag 604 presses against the flexible top piece 505 and bulges outward, closely fitting with the surface of the second bending piece 509, enhancing its sealing performance, preventing the relatively thin glue from oozing out, and at the same time being able to gradually squeeze out the glue adhered to the two surfaces, reducing the glue residue on the rectangular opening 504 surface at the port of the dispensing needle 4 and the surface of the second bending piece 509. At the same time, during each upward rotation of the telescopic inner plate 503, the side of the telescopic inner plate 503 can also scrape against the other two surfaces of the inner wall of the dispensing needle 4, scraping up the glue adhered to its surface, preventing the glue remaining at the end of the dispensing needle 4 from drying and affecting the glue dispensing.

[0036] An airbag driving component 6 is installed on the side of the dispensing needle 4. The airbag driving component 6 is used to drive the telescopic outer plate 502 and the telescopic inner plate 503 to rotate upward obliquely. The airbag driving component 6 includes a storage cavity 605. The storage cavity 605 is fixedly connected to the side of the dispensing needle 4. A driven airbag 604 is arranged inside the storage cavity 605. One end of the driven airbag 604 is fixedly connected to the storage cavity 605, and the other end of the driven airbag 604 has a clearance fit with the flexible top piece 505. A driving airbag 601 is arranged at the bottom of the annular plug seat 707. An extrusion top plate 602 is fixedly connected to the side of the plug 706. The top end of the driving airbag 601 is fixedly connected to the annular plug seat 707, and the bottom end of the driving airbag 601 is fixedly connected to the extrusion top plate 602. An air vent hose 603 is communicated with the side of the driving airbag 601.

[0037] When the plug 706 moves upward, it drives the extrusion top plate 602 to move upward together, squeezing the active airbag 601. The gas stored at the bottom inside the active airbag 601 can then flow through the ventilation hose 603 to the driven airbag 604. The driven airbag 604 is in an inflated state and can tilt and rotate upward from the side against the telescopic outer plate 502 and the telescopic inner plate 503, completing the plugging of the bottom end of the dispensing needle 4 to prevent glue leakage. When dispensing is required, the plug 706 moves downward, driving the extrusion top plate 602 to move downward together. The active airbag 601 is in a stretched state, and its internal space expands. The air inside the driven airbag 604 is drawn back through the ventilation hose 603. As a result, the telescopic outer plate 502 and the telescopic inner plate 503 can rotate downward. At the same time, after the second bending piece 509 loses support, it also falls, allowing the glue to flow downward through the dispensing needle 4.

[0038] A piston pressurizing assembly 7 is installed inside the dispensing cylinder 3. The piston pressurizing assembly 7 is used to extrude the glue. The piston pressurizing assembly 7 includes a hydraulic push rod 701. The hydraulic push rod 701 is fixedly connected to the top of the dispensing cylinder 3. The output end of the hydraulic push rod 701 is fixedly connected to a piston rod 702. A limiting chute 704 is formed on the side of the piston rod 702, and a limiting slider 705 is slidably connected inside the limiting chute 704. A glue-pushing piston 703 is fixedly connected to the side of the limiting slider 705, and the glue-pushing piston 703 is slidably connected to the piston rod 702. A plug 706 is slidably connected to the outside of the piston rod 702. An annular plug seat 707 is fixedly connected to the inner wall of the dispensing cylinder 3. A third spring 709 is fixedly connected to the bottom of the plug 706, and the third spring 709 is sleeved on the outside of the piston rod 702. The bottom end of the third spring 709 is fixedly connected to an anti-detachment stopper 708, and the anti-detachment stopper 708 is fixedly connected to the piston rod 702.

[0039] The output end of the hydraulic push rod 701 moves the piston rod 702 up and down. When the piston rod 702 moves upward, the anti-slip block 708 at its bottom moves upward against the sealing plug 706 through the third spring 709, and the annular plug seat 707 is blocked by the sealing plug 706. At the same time, the sealing plug 706 compresses the active airbag 601 with the extrusion top plate 602, and the bottom end of the dispensing needle 4 is also blocked through transmission. Then the piston rod 702 continues to move upward, and when the limit slider 705 contacts the bottom end of the limit slide groove 704, it will The glue pushing piston 703 moves upward together, and the volume of the cavity between the glue pushing piston 703 and the annular plug seat 707 becomes larger, and the glue is drawn from the glue inlet pipe 10 into the interior of the glue dispensing cylinder 3 by using negative pressure. When glue dispensing is needed, the piston rod 702 moves downward, and the sealing plug 706 is separated from the annular plug seat 707, so that the annular plug seat 707 is in an open state. At the same time, when the limiting slider 705 contacts the top of the limiting slide groove 704, the glue pushing piston 703 moves downward therewith, so that the glue in the inner cavity of the glue dispensing cylinder 3 can be squeezed downward through the glue dispensing needle 4.

[0040] A lamp conveying assembly 8 is provided at the bottom of the dispensing needle 4, and the lamp conveying assembly 8 includes a supporting side panel 801, and the supporting side panel 801 is fixedly connected to the top of the dispensing device bottom plate 1, and a conveyor belt 802 is installed on the inner wall of the supporting side panel 801, and an electric push rod 803 is provided on the side of the conveyor belt 802, and the electric push rod 803 is fixedly connected to the top of the dispensing device bottom plate 1, and the output end of the electric push rod 803 is fixedly connected to a lifting push plate 804, and a positioning plate 805 is provided on the top of the lifting push plate 804, and the positioning plate 805 is fixedly connected to the supporting side panel 801.

[0041] The LED lamp shell that needs to be glued is transported forward by the conveyor belt 802. When it is transported to the top of the lifting push plate 804, the electric push rod 803 moves upward with the lifting push plate 804 to lift the lamp shell, and cooperates with the positioning plate 805 to clamp and position the lamp shell from the upper and lower sides. When the glue dispensing is completed, the electric push rod 803 moves downward with the lifting push plate 804. When the lifting push plate 804 is lower than the conveyor belt 802, the lamp shell falls on the conveyor belts 802 on both sides again and continues to be transported forward.

[0042] A glue injection tube 3 is fixedly connected to the side of a glue inlet pipe 10. The top of the glue inlet pipe 10 is fixedly connected to a glue replenishing chamber 11. The side of the glue replenishing chamber 11 is fixedly connected to a glue replenishing pipe 12. The top end of the glue replenishing pipe 12 is fixedly connected to a glue storage barrel 13, and the glue storage barrel 13 is fixedly connected to the top of a transmission mechanism 2. A one-way glue inlet assembly 9 is installed inside the glue inlet pipe 10. The one-way glue inlet assembly 9 includes a second spring 901. One end of the second spring 901 close to the glue injection tube 3 is fixedly connected to the glue inlet pipe 10, and the end of the second spring 901 far from the glue injection tube 3 is fixedly connected to a plugging valve core 902. A plugging valve seat 903 is sleeved outside the plugging valve core 902, and the plugging valve seat 903 is fixedly connected to the inner wall of the glue inlet pipe 10.

[0043] When the glue pushing piston 703 moves upward, under the action of the negative pressure inside the glue injection tube 3, the glue has a tendency to flow into the glue injection tube 3, thereby squeezing the second spring 901, causing the plugging valve core 902 to disengage from the plugging valve seat 903, and the plugging valve seat 903 is in an open state. The glue inside the glue replenishing chamber 11 can flow into the glue injection tube 3 through the glue inlet pipe 10. When the glue pushing piston 703 moves downward, under the action of the second spring 901, the plugging valve core 902 is inserted into the inside of the plugging valve seat 903 for plugging to prevent the glue inside the glue injection tube 3 from flowing back through the glue inlet pipe 10.
