Abstract

The invention discloses a glue dispensing device for processing LED lamps, and relates to the technical field of glue dispensing. By utilizing the cooperation between an airbag in an airbag driving component and a glue anti-drip component, the bottom end of a glue dispensing needle can be effectively blocked while glue is not being dispensed, thereby preventing glue from dripping, and further effectively preventing the formation of a wire drawing phenomenon between the needle and the surface of a glued object.

Each time glue dispensing and blocking are performed, the glue at the bottom end of the glue dispensing needle can be cleaned. Cleaning the needle can prevent the glue from drying at the bottom end of the needle, ensure that the glue is squeezed out of the needle at a uniform and stable flow rate, and can effectively reduce the probability of needle blockage, reduce the time of equipment downtime due to needle blockage, improve the continuous operation capability of the equipment, and thus improve the overall production efficiency.

Description

Technical Field

[0001] The invention relates to the technical field of glue dispensing, in particular to a glue dispensing device for processing LED lamps. Background Art

[0002] In the production of LED lamps, sealants are used at the joints of the lamp shell to seal the lamp body. Commonly used sealants are silicone sealants, which have good flexibility and weather resistance. Silicone sealants can maintain good sealing performance within the temperature range of -50℃-200℃, effectively preventing rain, sand and dust from entering the interior of the lamp. Sealant can also enhance the mechanical strength of the lamp body, resist external impact and pressure to a certain extent, and maintain the integrity of the lamp body structure.

[0003] In this regard, the patent CN118904650B discloses a glue dispensing machine and glue dispensing process for LED lamps to prevent glue from dripping, including a moving unit and a glue dispensing head; a glue outlet groove is vertically opened at the lower part of the glue dispensing head, and glue flows out from the glue outlet groove; a blocking block is slidably arranged in the glue dispensing head along the extension direction of the glue outlet groove; a pressing frame is arranged at the upper part of the glue dispensing head to reciprocate in the vertical direction; the blocking block and the pressing frame move in the vertical direction in the opposite direction; 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 an extrusion force on the storage cavity, and the blocking block completely gives up the glue outlet groove. The present invention ensures that the glue dispensing head will not leak glue when dispensing.

[0004] The above-mentioned glue dispensing device for LED lamp processing adopts a sealing block that moves from top to bottom to seal the glue at the needle head, and cooperates with the through hole set on the side to absorb the glue remaining at the needle head. There is a certain wear and tear due to the repeated up and down reciprocating movement of the sealing block, and there is a certain gap between it and the wall of the needle tube. Some glue with thinner texture may still seep downward from the gap, and when the through hole draws out the glue at its end, a thin layer of glue still remains on the inner wall of the needle end. 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 layers of glue dried on the inner wall of the needle end will reduce the inner diameter of the top of the needle, block the needle, and cause the problem of unstable glue output.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0024] Combination Figure 1-Figure 10A glue dispensing device for processing LED lamps of the present invention comprises a glue dispensing device bottom plate 1, a top plate of the glue dispensing device bottom plate 1 is provided with a transmission mechanism 2, an output end of the transmission mechanism 2 is fixedly connected to a glue dispensing cylinder 3, a glue dispensing needle 4 is fixedly connected to the bottom of the glue dispensing cylinder 3, a glue anti-drip component 5 is installed inside the glue dispensing needle 4, the glue anti-drip component 5 comprises a first flexible connecting piece 501, and the first flexible connecting piece 501 is fixedly connected to the inner wall of the glue dispensing needle 4, a telescopic outer plate 502 is fixedly connected to the bottom of the first flexible connecting piece 501, 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 plate 505 is fixedly connected inside the rectangular opening 504, a second flexible connecting piece 506 is fixedly connected to the side of the inner wall of the glue dispensing needle 4 away from the first flexible connecting piece 501, and the bottom of the second flexible connecting piece 506 is fixedly connected There is a first bending piece 507, and the bottom of the first bending piece 507 is fixedly connected to the third flexible connecting piece 508, the bottom of the third flexible connecting piece 508 is fixedly connected to the second bending piece 509, the end gap of the second bending piece 509 is matched with the limiting strip 510, and the limiting strip 510 is fixedly connected to the inner wall of the dispensing needle 4, and a first spring 511 is also 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 and the telescopic outer plate 502 are slidably connected, 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 can just contact the bottom end of the second bending piece 509, and when it gradually rotates upward, the first spring 511 can be compressed to adaptively adjust its total length.

[0025] When the driven airbag 604 is in an inflated state, the driven airbag 604 pushes the telescopic outer plate 502 and the telescopic inner plate 503 from the side and tilts upward. When it rotates to a certain extent, the bottom edge of the telescopic inner plate 503 contacts the bottom edge of the second bending piece 509. In the process of gradually tilting upward, the telescopic inner plate 503 pushes the second bending piece 509 and gradually moves upward, so that the second bending piece 509 and the first bending piece 507 form a bend. In the process of the telescopic inner plate 503 gradually tilting upward and the second bending piece 509 gradually bending, a V-shaped space with an opening facing upward is formed between the flexible top sheet 505 and the second bending piece 509, and the V-shaped opening gradually shrinks, gradually squeezing the glue inside it back into the inside of the glue dispensing needle 4. When the bottom end of the bending piece 509 gradually moves upward and contacts the limit strip 510, it is blocked by the limit strip 510 and the second bending piece 509 will not continue to bend. At the same time, the driven airbag 604 bulges outward against the flexible top sheet 505, and fits tightly with the surface of the second bending piece 509, thereby enhancing its sealing performance and preventing the thinner glue from seeping out. At the same time, the glue adhering to the two surfaces can be gradually squeezed out, thereby reducing the glue residue on the rectangular opening 504 surface at the port of the glue dispensing needle 4 and the second bending piece 509 surface. At the same time, during each upward rotation of the telescopic inner plate 503, the side of the telescopic inner plate 503 can also scratch the other two surfaces of the inner wall of the glue dispensing needle 4, and scrape the glue adhering to its surface upward, thereby preventing the glue remaining at the end of the glue dispensing needle 4 from drying up and affecting the glue discharge.

[0026] An airbag driving assembly 6 is installed on the side of the dispensing needle 4, and the airbag driving assembly 6 is used to drive the telescopic outer plate 502 and the telescopic inner plate 503 to tilt upward and rotate. The airbag driving assembly 6 includes a storage cavity 605, and 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, and one end of the driven airbag 604 is fixedly connected to the storage cavity 605, and the other end of the driven airbag 604 is gap-fitted with the flexible top sheet 505. An active airbag 601 is arranged at the bottom of the annular plug seat 707, and the side of the sealing plug 706 is fixedly connected with the extrusion top plate 602, the top of the active airbag 601 is fixedly connected to the annular plug seat 707, and the bottom end of the active airbag 601 is fixedly connected to the extrusion top plate 602, and the side of the active airbag 601 is connected with a ventilation hose 603.

[0027] When the sealing plug 706 moves upward, it moves upward with the extrusion top plate 602 to squeeze the active airbag 601, and the gas stored at the bottom of the active airbag 601 can flow to the driven airbag 604 through the ventilation hose 603. When the driven airbag 604 is in an inflated state, it can be tilted and rotated upward from the side against the telescopic outer plate 502 and the telescopic inner plate 503 to complete the sealing of the bottom end of the dispensing needle 4 to prevent glue from leaking. When glue is needed, the sealing plug 706 moves downward, moving downward with the extrusion top plate 602. The active airbag 601 is in a stretched state, and its internal space is expanded. The air inside the driven airbag 604 is drawn back through the ventilation hose 603, so that the telescopic outer plate 502 and the telescopic inner plate 503 can be turned back downward. At the same time, the second bending piece 509 is also in a falling state after losing its support, so that the glue can flow downward through the dispensing needle 4.

[0028] A piston pressurizing assembly 7 is installed inside the glue dispensing cylinder 3, and the piston pressurizing assembly 7 is used to squeeze out the glue. The piston pressurizing assembly 7 includes a hydraulic push rod 701, which is fixedly connected to the top of the glue dispensing cylinder 3, and the output end of the hydraulic push rod 701 is fixedly connected to a piston rod 702, and a limiting slide groove 704 is provided on the side of the piston rod 702, and the limiting slide groove 704 is internally slidably connected to a limiting slider 705, and the side of the limiting slider 705 is fixedly connected to a glue pushing piston 703, and the glue pushing piston 703 is slidably connected to the piston rod 702, and the outside of the piston rod 702 is slidably connected to a sealing plug 706, and the inner wall of the glue dispensing cylinder 3 is fixedly connected to an annular plug seat 707, and the bottom of the sealing plug 706 is fixedly connected to a third spring 709, and the third spring 709 is sleeved on the outside of the piston rod 702, and the bottom end of the third spring 709 is fixedly connected to an anti-detachment block 708, and the anti-detachment block 708 is fixedly connected to the piston rod 702.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] A glue feed pipe 10 is fixedly connected to the side of the glue dispensing cylinder 3, and a glue replenishing chamber 11 is fixedly connected to the top of the glue feed pipe 10, a glue replenishing pipe 12 is fixedly connected to the side of the glue replenishing chamber 11, a glue storage barrel 13 is fixedly connected to the top of the glue replenishing pipe 12, and the glue storage barrel 13 is fixedly connected to the top of the transmission mechanism 2, and a one-way glue feed component 9 is installed inside the glue feed pipe 10, and the one-way glue feed component 9 includes a second spring 901, and one end of the second spring 901 close to the glue dispensing cylinder 3 is fixedly connected to the glue feed pipe 10, and the end of the second spring 901 away from the glue dispensing cylinder 3 is fixedly connected to a blocking valve core 902, the outer sleeve of the blocking valve core 902 is provided with a blocking valve seat 903, and the blocking valve seat 903 is fixedly connected to the inner wall of the glue feed pipe 10.

[0033] When the glue pushing piston 703 moves upward, under the action of the negative pressure inside the glue dispensing cylinder 3, the glue tends to flow into the glue dispensing cylinder 3, thereby squeezing the second spring 901, so that the blocking valve core 902 is separated from the blocking valve seat 903, and the blocking valve seat 903 is in an open state. The glue inside the glue replenishing cavity 11 can flow into the glue dispensing cylinder 3 through the glue inlet pipe 10. When the glue pushing piston 703 moves downward, under the action of the second spring 901, the blocking valve core 902 is inserted into the blocking valve seat 903 for blocking, thereby preventing the glue inside the glue dispensing cylinder 3 from flowing back through the glue inlet pipe 10.
