Description

Technical Field

[0001] This utility model relates to the field of lampshade production technology, specifically to an automatic glue applicator for lampshade encapsulation. Background Technology

[0002] Currently, during the lamp cover encapsulation process, it is usually necessary to apply adhesive to seal the outer edge of the lamp holder to ensure a strong bond and airtightness between the lamp cover and the lamp holder. Existing automatic adhesive dispensing equipment generally uses a motor-driven pump to supply adhesive. A single rotor or screw structure transports the molten adhesive from the glue cylinder to the dispensing port, and then a fixed nozzle applies adhesive to the outer edge of the lamp holder by dispensing or linearly coating.

[0003] In existing technologies, common pumping mechanisms are mostly single-wheel extrusion or screw rotation structures. These structures are susceptible to problems during adhesive supply due to poor pump chamber sealing or backflow, leading to uneven adhesive application, localized leakage, or intermittent supply, making it difficult to guarantee continuous and stable adhesive application. Furthermore, some adhesive applicators use fixed nozzles with high nozzle hardness. Improper contact with the lamp holder can easily scratch the holder or cause uneven adhesive application, thus affecting the encapsulation quality.

[0004] On the other hand, existing glue supply cylinders mostly rely on external heating jackets or constant temperature chambers for overall heating, which has limited temperature control precision. During the transfer process, the glue is prone to local solidification or insufficient fluidity due to uneven temperature, causing nozzle blockage or poor glue dispensing, affecting the continuous operation of the equipment. In addition, existing equipment relies heavily on manual adjustment or simple timing control for the synchronous control of lamp holder rotation and glue dispensing, making it difficult to achieve precise rotation and coordination of the lamp holder along the circumferential trajectory. The glue dispensing process is prone to deviation or overlap, reducing the consistency of the finished product.

[0005] Therefore, there is an urgent need for an automatic glue applicator that can achieve stable glue supply, flexible and uniform glue dispensing, and has constant temperature control and synchronous rotation functions, so as to improve the reliability and production efficiency of lamp cover encapsulation. Utility Model Content

[0006] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0007] Therefore, the technical solution adopted by this utility model is as follows: an automatic glue applicator for lampshade encapsulation, comprising a tooling base, a glue dispensing assembly, and a hot glue cylinder. The tooling base has a servo motor base on its surface for driving the lampshade to rotate; the hot glue cylinder is fixed to the surface of the glue dispensing assembly, with its dispensing head facing the outer edge of the tooling lampshade on the servo motor base; the glue dispensing assembly includes a fixed base, a pump box, and a drive motor. The pump box has a rotating cavity inside, and a rotating wheel is rotatably installed in the rotating cavity. The surface of the rotating wheel has several tangential grooves, and a sliding plate and a spring are slidably installed in each groove; the bottom of the pump box has a transmission gear connected to the rotating wheel. The two rotating wheels rotate synchronously through the meshing of the transmission gear. The output end of the drive motor meshes with one of the transmission gears to drive the two rotating wheels to rotate synchronously, thereby completing the intermittent suction and pressure delivery of the glue.

[0008] In a preferred embodiment, the servo mount is further configured such that it includes a motor and a tooling clamp structure. The tooling clamp surface is equipped with a clamp that can rotate continuously in the horizontal direction, thereby driving the lamp holder to rotate along a circumferential trajectory below the dispensing head. Specifically, this structure ensures that the adhesive is evenly distributed along the outer edge of the lamp holder during rotation, achieving full-circumference dispensing.

[0009] In a preferred embodiment, the hot glue cartridge is further configured such that a glue dispensing head is provided at the bottom end. This dispensing head is flexible and used to evenly apply glue to the outer edge of the lamp holder. Specifically, this structure avoids scratching the lamp holder due to an overly hard nozzle, while improving the adhesion and uniformity of the glue application process.

[0010] In a preferred embodiment, the rotor's axis is offset from the axis of the rotating sleeve cavity, and one end of each sliding vane slides against the inner side of the rotating sleeve cavity. Specifically, this eccentric design can create periodic volume changes during rotation, achieving stable suction and delivery of the adhesive, and ensuring the continuity and reliability of the pumping process.

[0011] In a preferred embodiment, the roller is further configured such that the grooves on the roller are distributed tangentially, and each groove contains a sliding plate and a spring. The spring pushes the sliding plate to always keep it in close contact with the inner wall of the rotating sleeve cavity. Specifically, this design can form a sealed chamber when the roller rotates, effectively improving pumping sealing, preventing glue leakage, and improving glue dispensing stability.

[0012] In a preferred embodiment, the rotating chamber, pump box, and dispensing head are further configured in two sets, symmetrically arranged, with the two rotating wheels synchronously driven by a transmission gear at the bottom. Specifically, this structure enables parallel dispensing of adhesive using two pumps, increasing flow rate while maintaining stability, thus meeting the requirements for large-size lampshade encapsulation.

[0013] In a preferred embodiment, the rotating sleeve cavity surface is further configured with an inlet and an outlet, which are symmetrically arranged about the axis of the rotating wheel. The outlet is connected to the end of the hot glue cylinder, and the axis of the rotating wheel is offset from the side closest to the outlet. Specifically, this design ensures smooth flow of the glue between the inlet and outlet, reduces backflow, and improves glue supply efficiency.

[0014] In a preferred embodiment, the hot glue cylinder is further configured such that an electric heating coil is installed inside, and the input end of the electric heating coil is electrically connected to a temperature control component for heating the glue liquid inside the hot glue cylinder. Specifically, this structure can maintain the appropriate fluidity of the glue liquid, prevent nozzle clogging due to cooling and solidification, and improve the continuous working capability of the equipment.

[0015] In summary, this utility model achieves stable glue supply, uniform glue application, and efficient operation by using a servo motor base to drive the lamp holder to rotate circumferentially, combined with a flexible glue dispensing head for glue application, an eccentric wheel-slider pumping structure, symmetrical dual-pump glue supply, and a temperature-controlled hot glue cylinder. This effectively improves the reliability and production efficiency of lamp cover encapsulation.

[0016] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, by setting an eccentrically arranged rotating wheel, a tangential sliding groove, and a cooperative structure of sliding plate and spring inside the glue feeding assembly, a stable sealed chamber can be formed during the rotation of the rotating wheel, realizing the intermittent suction and pressure feeding of glue; at the same time, through the synchronous meshing transmission of the two rotating wheels and the transmission gear, the glue supply process is made more continuous and uniform, avoiding the problems of unstable glue supply, glue leakage or glue blockage in the prior art, thereby significantly improving the consistency and reliability of glue application.

[0017] 2. In this utility model, the servo motor base drives the tool lamp holder to rotate along a circumferential trajectory. Combined with the constant temperature glue supply of the flexible glue dispensing head at the bottom of the hot glue cylinder, it can ensure that the glue is evenly distributed on the outer edge of the lamp holder, avoiding uneven glue application or damage to the lamp holder surface caused by unstable temperature or nozzle hardening. This design not only improves the glue application accuracy and appearance quality, but also enhances the automation level and production efficiency of the lamp cover encapsulation process.

It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0021] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0022] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, an automatic glue applicator for lampshade encapsulation.

[0023] Combination Figures 1-5 As shown, the present invention provides an automatic glue applicator for lampshade encapsulation, comprising a tooling base 100, a glue feeding assembly 200, and a hot glue cylinder 300.

[0024] The tooling base 100 has a servo motor base 110 on its surface for driving the lamp holder to be processed to rotate. The hot glue cylinder 300 is fixedly installed on the surface of the glue delivery assembly 200, and its glue outlet 310 faces the outer edge of the tooling lamp holder on the servo motor base 110 to ensure uniform distribution of glue during lamp holder rotation. The glue delivery assembly 200 includes a fixed base 210, a pump box 220, and a drive motor 230. The pump box 220 has a rotating sleeve cavity 221, and a rotating wheel 222 is rotatably installed inside the rotating sleeve cavity 221. The surface of the rotating wheel 222 has several tangentially arranged sliding grooves, and a sliding plate 223 and a spring 224 are slidably installed in each groove. The bottom surface of the pump box 220 has a transmission gear 231 connected to the rotating wheel 222. The bottom ends of the two rotating wheels 222 mesh with each other through the transmission gear 231. The output end of the drive motor 230 meshes with the surface of one of the transmission gears 231 to drive the two rotating wheels 222 to rotate synchronously. Specifically, this structure can achieve stable pumping of molten adhesive under the drive of the drive motor 230, ensuring a continuous and uniform dispensing process.

[0025] In a preferred embodiment, the servo motor base 110 includes a motor and a tooling clamp structure. The tooling clamp surface is provided with a clamp for fixing the lamp holder, and the servo motor base 110 can rotate continuously in the horizontal direction. Specifically, through the rotation of the servo motor base 110, the lamp holder can move along a circumferential trajectory below the glue dispensing head 310, thereby achieving full circumferential glue dispensing at the outer edge position.

[0026] In another embodiment, the bottom end of the hot glue cylinder 300 is provided with a glue dispensing head 310, which is a flexible glue nozzle. Specifically, this design ensures that the glue dispensing process is close to the outer edge of the lamp holder, avoiding problems such as scratches on the lamp holder or uneven glue application caused by a hard nozzle, thereby improving the uniformity of glue application and the appearance quality of the product.

[0027] In a preferred embodiment, the axis of the rotating wheel 222 is offset relative to the axis of the rotating sleeve cavity 221, and one end of each sliding piece 223 slides against the inner wall of the rotating sleeve cavity 221. Specifically, this eccentric structure can form periodic compression and expansion zones of the adhesive during rotation, thereby ensuring stable transmission of the molten adhesive during pumping.

[0028] like Figure 4 and Figure 5 As shown, the grooves of the rotating wheel 222 are distributed tangentially, and each groove is equipped with a sliding plate 223 and a spring 224. The spring 224 is used to push the sliding plate 223 to always keep it in close contact with the inner wall of the rotating sleeve cavity 221, so as to form a sealed chamber during rotation, realizing the intermittent suction and pressure delivery of the adhesive. Specifically, this structure can effectively improve the airtightness and adhesive dispensing stability of the pump, and avoid adhesive leakage or insufficient adhesive supply.

[0029] In another embodiment, the rotating cavity 221, pump box 220, and dispensing head 310 are in two sets and arranged symmetrically. The bottom ends of the two rotating wheels 222 are respectively connected to the transmission gears 231, and the two transmission gears 231 mesh with each other to achieve synchronous rotation of the two rotating wheels 222. Specifically, this structure, through parallel dispensing of adhesive by two pumps, can improve the dispensing flow rate and stability, meeting the encapsulation requirements of large-size lamp covers.

[0030] Furthermore, the surface of the rotating sleeve cavity 221 is provided with an inlet and an outlet, which are symmetrically arranged with the axis of the rotating wheel 222 as the origin. The outlet is connected to the end of the hot glue cylinder 300, and the axis of the rotating wheel 222 is offset to the side closer to the outlet. Specifically, this structure can ensure that the glue forms a smooth flow path between the inlet and outlet, improve pumping efficiency, and avoid unstable glue supply caused by glue backflow.

[0031] In another preferred embodiment, the hot glue cylinder 300 is equipped with an electric heating coil, the input end of which is electrically connected to a temperature control component for heating the glue liquid inside the hot glue cylinder 300. Specifically, this heating and temperature control design ensures that the glue liquid is always in a suitable flow state, avoiding blockage problems caused by the glue liquid cooling and solidifying, thereby improving the continuous working capacity of the equipment.

[0032] In summary, this utility model achieves automatic glue application of the lamp holder along a circumferential trajectory through the cooperation of the servo motor base 110 and the glue dispensing head 310. Combined with the pumping mechanism of the eccentric rotating wheel 222, the sliding plate 223 and the spring 224, as well as the double symmetrically arranged rotating sleeve cavity 221 and the temperature-controlled hot glue cylinder 300, it achieves the technical effects of stable glue supply, uniform glue application and efficient operation, which can significantly improve the automation level and production efficiency of the lamp cover packaging process.
