Description

Technical Field

[0001] This utility model belongs to the field of LED lamp holder technology, and in particular relates to an LED lamp holder unloading and feeding device. Background Technology

[0002] An LED light bracket is a base structure used to fix, support, and carry LED light strips or panels, typically made of materials such as metal or plastic. It provides a stable mounting base for LED lights and also serves multiple functions including heat dissipation, protection, and aesthetics. The light bracket ensures effective light guidance and uniform diffusion, while extending the lifespan of the LEDs. After being manufactured using a mold, the LED light bracket needs to be demolded using an ejector mechanism. After demolding, it requires a vacuum suction cup for material transfer.

[0003] Chinese patent discloses an LED lamp holder unloading and feeding device (authorization announcement number CN214395241U). The patented technology includes a lower mold assembly and a mold frame plate. The LED lamp holder is located on the mold frame plate, and the LED lamp holder has evenly distributed lamp bead holders. The lower mold assembly is embedded with a push rod, a first ejector assembly and a second ejector assembly. A rotatable rocker assembly is provided between the first ejector assembly and the second ejector assembly.

[0004] However, existing technologies have the following problems when used: Firstly, the existing method of using a pin mechanism to remove the film from LED lamp brackets is difficult to adjust the force according to the material and structure of the bracket. Excessive pushing force can easily cause the bracket to deform and crack, and the limited contact points can lead to uneven force distribution. Complex or large brackets are prone to sticking together. In addition, the lack of an auxiliary removal structure makes the removal unstable and incomplete, which reduces efficiency and wastes materials and increases costs due to bracket damage. Secondly, existing vacuum suction cups for material adsorption have a fixed adsorption area and force, making it difficult to adapt to different brackets. Small or irregular brackets are prone to detachment, while large brackets are prone to deformation. Furthermore, the system's poor sealing and negative pressure stability can easily lead to pressure leakage, causing bracket displacement, disrupting production, affecting subsequent connections, and potentially damaging the brackets and shortening the LED's lifespan.

[0021] Please see Figures 1 to 6 The embodiments provided by this utility model are as follows: Example: An LED lamp holder unloading and feeding device, comprising: The lower mold 1 is equipped with an ejector pin mechanism 3 in its inner cavity and a vent plate 2 in its inner cavity. The lower end of the lower mold 1 is connected to a hose 4, and the end of the hose 4 away from the lower mold 1 is connected to a pump body 5 for introducing gas into the hose to remove the LED lamp bracket in the lower mold 1. The upper end of the pump body 5 is connected to a flexible hose 2 6, and the end of the flexible hose 2 6 away from the pump body 5 is connected to a pipe 1 12. A circular cover 9 is installed at the lower end of the pipe 1 12, and the lower end of the pipe 1 12 passes through the top of the circular cover 9 and extends into the inner cavity of the circular cover 9. The lower end of the pipe 1 12 inside the inner cavity of the circular cover 9 is connected to a circular shell 18. Multiple air guide pipes 14 are installed on the outer wall of the circular shell 18, and multiple air guide heads 15 are installed at intervals on each air guide pipe 14. An adsorption plate 16 is installed in the inner cavity of the circular cover 9 for adsorbing and passing the LED lamp bracket after dematerialization.

[0022] In the example of this application, the lower mold 1 provides a crucial load-bearing space for the forming and unloading of the LED lamp bracket. The ejector pin mechanism 3 installed in its inner cavity, in conjunction with the gas during the unloading process, further assists in the separation of the LED lamp bracket from the inner wall of the lower mold 1, preventing the bracket from getting stuck or damaged during unloading. The vent plate 2 installed in the inner cavity ensures the uniform distribution of gas, allowing the gas introduced by the pump body 5 through the hose-4 to act smoothly and evenly on the LED lamp bracket inside the lower mold 1, ensuring the stability of the unloading process and effectively reducing the bracket deformation problem caused by uneven gas distribution. In the material handling stage, pump body 5 is connected to pipe 12 via hose 2 6, transmitting power to the area of ​​the dome 9. The lower end of pipe 12 extends into the inner cavity of the dome 9 and connects to the dome shell 18. Multiple air guide pipes 14 installed on the outer wall of the dome shell 18 and multiple air guide heads 15 spaced apart on each air guide pipe 14 can disperse and conduct gas, creating suitable adsorption conditions for the adsorption plate 16. When pump body 5 performs air extraction, the inner cavity of the dome 9 forms a stable negative pressure environment through the air guide pipes 14 and air guide heads 15, allowing the adsorption plate 16 to fit tightly against the LED lamp holder, thereby reliably adsorbing the dematerialized LED lamp holder. Combined with the external moving mechanism, the material handling is completed. The entire process requires no manual intervention, which not only improves the material handling efficiency but also avoids the contamination or damage to the LED lamp holder that may be caused by manual contact.

[0023] Furthermore, the upper end of the vent plate 2 is provided with a through hole 19, and the lower end of the vent plate 2 is provided with a groove 21. The inner wall of the groove 21 and the inner cavity wall of the lower mold 1 together form a sealed space. The ejector pin mechanism 3 is correspondingly installed in the space formed by the hole wall of the through hole 19 and the inner cavity wall of the lower mold 1.

[0024] As a preferred example of this utility model, the through hole 19 at the upper end of the vent plate 2, together with the inner wall of the lower mold 1, forms a space that provides positioning for the installation of the ejector mechanism 3. This ensures that the ejector mechanism 3 can act on the designated position of the LED lamp bracket during operation, avoiding problems such as bracket damage or incomplete stripping due to ejector position deviation. Simultaneously, the groove 21 at the lower end of the vent plate 2, together with the inner wall of the lower mold 1, forms a sealed space. This sealed space effectively gathers the gas introduced by the pump body 5 through the hose 4, creating a stable pressure within the sealed environment. The pressure is then evenly transmitted to the bottom of the LED lamp bracket through the permeability of the vent plate 2 itself. Combined with the pushing action of the ejector mechanism 3, this achieves efficient stripping of the LED lamp bracket. This ensures effective utilization of gas pressure and further improves the reliability of stripping through the synergistic effect of the ejector and gas. It is particularly suitable for stripping LED lamp brackets with complex structures or brittle materials, effectively reducing the stripping failure rate.

[0025] Furthermore, a pipe 20 is installed at the lower end of the lower mold 1, and the pipe 20 is connected to the inner cavity of the lower mold 1. A hose 4 is connected to the pipe 20. A connecting pipe 10 is installed at the lower end of the pump body 5, and the end of the hose 4 away from the lower mold 1 is connected to the connecting pipe 10.

[0026] As a preferred example of this utility model, the second pipe 20 installed at the lower end of the lower mold 1 is directly connected to the inner cavity of the lower mold 1. This ensures that the gas or negative pressure generated by the pump body 5 directly acts on the inner cavity of the lower mold 1, reducing gas loss during transmission and ensuring the stability of gas pressure or negative pressure. The connecting pipe 10 installed at the lower end of the pump body 5 provides an interface for the connection between the hose 4 and the pump body 5, making the installation and disassembly of the hose 4 more convenient and reducing the difficulty of equipment maintenance. At the same time, this connection method via the second pipe 20 and the connecting pipe 10 effectively avoids problems such as loose interfaces and air leakage that may occur when the hose 4 is directly connected to the lower mold 1 and the pump body 5, ensuring the sealing of the gas transmission channel, thereby ensuring the stability of gas pressure during the unloading process and further improving the reliability and consistency of the unloading operation.

[0027] Furthermore, a connecting pipe 2 11 is installed on the upper end of the pump body 5, and a flexible hose 2 6 is connected to the connecting pipe 2 11.

[0028] As a preferred example of this utility model, the connecting pipe 11, serving as a transitional connection between the pump body 5 and the hose 6, effectively disperses the stress generated during the connection of the hose 6, preventing problems such as interface wear and breakage caused by long-term use or frequent movement of the hose, thus extending the service life of the hose 6. Simultaneously, the connecting pipe 11 makes the connection between the hose 6 and the pump body 5 more secure, ensuring the airtightness of gas transmission during the material handling process and preventing insufficient negative pressure inside the dome 9 due to air leakage at the interface, which would affect the adsorption effect of the adsorption plate 16 on the LED lamp holder. Furthermore, the interface of the connecting pipe 11 facilitates the replacement and maintenance of the hose 6, reducing maintenance costs during long-term operation, ensuring the continuous stability of the material handling operation, and providing a guarantee for the efficient operation of the entire production process.

[0029] Furthermore, the circular cover 9 has a collection groove 22, and the pipe 12 is connected to the collection groove 22. The outer wall of the circular shell 18 has a circular hole 23, which is connected to the collection groove 22 and the air guide pipe 14.

[0030] As a preferred example of this utility model, the collecting groove 22 on the circular cover 9 is connected to the pipe 12, which can effectively collect the gas or negative pressure transmitted by the pump body 5 through the hose 6 and the pipe 12, avoiding uneven dispersion of gas in the inner cavity of the circular cover 9, and ensuring that the gas pressure or negative pressure can be concentrated on the subsequent gas conduction structure. The circular hole 23 on the outer wall of the circular shell 18 is connected to the collecting groove 22, realizing the transmission of gas or negative pressure in the collecting groove 22 to the interior of the circular shell 18, and is also connected to the gas guide pipe 14, so as to evenly distribute the gas or negative pressure to each gas guide pipe 14. This allows gas or negative pressure to enter the circular shell 18 from the collecting groove 22 through the circular hole 23, and then be evenly distributed to various areas of the inner cavity of the circular cover 9 through the air guide pipe 14 and the air guide head 15. This ensures that the adsorption plate 16 can form a uniform and stable adsorption force, thereby reliably adsorbing the LED lamp bracket and avoiding the problem of the bracket falling off or shifting position during the material feeding process due to uneven adsorption force. This significantly improves the safety and accuracy of the material feeding operation.

[0031] Furthermore, a circular groove 13 is provided at the lower end of the circular cover 9, and an adsorption plate 16 is provided in the circular groove 13, with an adsorption hole 17 at the lower end of the adsorption plate 16.

[0032] As a preferred example of this utility model, the structure of the circular groove 13 can form a good fit with the adsorption plate 16, reducing gas leakage during adsorption and further ensuring the stability of the adsorption environment below the adsorption plate 16. The adsorption hole 17 opened at the lower end of the adsorption plate 16 is a key structure for realizing the adsorption of LED lamp holders. When a negative pressure is formed in the inner cavity of the circular cover 9 under the action of the pump body 5, the adsorption hole 17 can transfer the negative pressure to the surface of the LED lamp holder, so that the holder is tightly attached to the lower end of the adsorption plate 16. The spacing of multiple adsorption holes 17 can ensure that the adsorption force is evenly distributed on the surface of the holder, avoiding excessive local adsorption force that causes the holder to deform, or insufficient local adsorption force that causes the holder to fall off. This not only ensures the reliability of adsorption, but also adapts to LED lamp holders of different sizes and shapes, improving the versatility of the device and providing support for diverse production needs.

[0033] Furthermore, a fixed plate 8 is fixed on the pipe 12, and a connecting plate 7 is fixed at the rear end of the fixed plate 8, and the connecting plate 7 is connected to an external moving lifting mechanism.

[0034] As a preferred example of this utility model, the fixed connection between the fixed plate 8 and the pipe 12 ensures the stable transmission of power from the external moving and lifting mechanism to the pipe 12 and its connected components such as the dome 9 and the suction plate 16. This guarantees that the components of the material handling mechanism will not experience relative displacement during movement and lifting, ensuring that the adsorbed LED lamp holders maintain a stable posture. The connecting plate 7, as the direct connection component to the external moving and lifting mechanism, has a structure adaptable to different types of external mechanisms, exhibiting strong compatibility and facilitating integration with different automated production lines according to actual production needs. Through the control of the external moving and lifting mechanism, the connecting plate 7 can drive the fixed plate 8, pipe 12, dome 9, and suction plate 16 to move and lift, thereby accurately conveying the adsorbed LED lamp holders to the designated position and completing the material handling operation. This not only significantly improves production efficiency but also avoids errors that may arise from manual operation, ensuring the accuracy of the material handling position and laying a solid foundation for the smooth progress of subsequent processes.

[0035] Furthermore, valves are installed on connecting pipe 10, connecting pipe 21, pipe 12, and pipe 20.

[0036] As a preferred example of this utility model, in the unloading stage, the flow rate and pressure of the gas supplied by the pump body 5 into the inner cavity of the lower mold 1 can be adjusted by controlling the valves on connecting pipe 10 and pipe 20. Appropriate unloading parameters can be adjusted according to the different specifications and materials of the LED light brackets, avoiding damage to the brackets due to excessive gas pressure or incomplete unloading due to insufficient pressure. In the conveying stage, the valves on connecting pipe 21 and pipe 12 can be controlled to adjust the pumping rate and negative pressure of the pump body 5 into the inner cavity of the circular cover 9, ensuring that the adsorption plate 16 can generate appropriate adsorption force, guaranteeing reliable adsorption of the brackets and facilitating smooth release of the brackets at designated positions. Furthermore, the valve configuration allows for independent control of the unloading and conveying stages, enabling flexible switching between the two stages according to the production rhythm. Multiple valve controls allow the device to adapt to different production conditions and product requirements, improving the equipment's versatility and the stability of the production process.

[0037] Furthermore, the permeable plate 2 is a porous ceramic plate for sampling.

[0038] As a preferred example of this utility model, the porous ceramic plate has a rich and uniform pore structure, allowing gas introduced into the lower mold 1 cavity by the pump body 5 through the hose 4 and pipe 20 to achieve full dispersion and penetration within the vent plate 2. This allows the gas to be evenly discharged from the upper surface of the vent plate 2 and applied to the bottom of the LED lamp holder. Compared to other permeable materials, the porous ceramic plate has a more uniform pore distribution, effectively avoiding uneven stress on the holder caused by localized gas concentration, and reducing the risk of holder deformation or damage. The porous ceramic plate also has good high-temperature resistance and corrosion resistance, enabling it to adapt to different environmental conditions that may occur during LED lamp holder production, ensuring stable performance of the vent plate 2 during long-term use and providing a reliable guarantee for the continuous and stable operation of the unloading process.

[0039] In this embodiment, when performing stripping and feeding operations on the LED lamp holder, firstly, during the LED lamp holder preparation stage, the upper mold and the lower mold 1 cooperate with each other to provide a sealed forming space for the LED lamp holder to be formed. After the LED lamp holder is prepared according to the preset specifications, the first step is to disassemble and separate the upper mold from the lower mold 1, thereby freeing up operating space for the subsequent stripping operation and ensuring that the stripping process is not hindered by external structures. After the upper mold is disassembled, the pump body 5, which serves as the power source, is started. At this time, the hose 4 connected to the lower end of the pump body 5 (connecting pipe 10) and the pipe 20 connected to the other end of the hose 4 begin to perform gas transmission. The gas generated by the pump body 5 is smoothly delivered to the pipe 20 through the hose 4, and then directly introduced into the groove 21 at the lower end of the vent plate 2 in the inner cavity of the lower mold 1. Since the groove 21 is a sealed space formed by the lower end of the vent plate 2 and the inner wall of the lower mold 1, the introduced gas gradually accumulates in this sealed space, forming a stable air pressure environment. Subsequently, the gas permeates evenly through the vent plate 2 due to its uniform pore structure and acts upwards on the bottom of the LED light bracket.

[0040] At the same time, the ejector mechanism 3, installed in the space enclosed by the through hole 19 of the vent plate 2 and the inner wall of the lower mold 1, is activated synchronously. The gas transmitted by the vent plate 2 provides auxiliary thrust for the ejector mechanism 3. The two work together, and the gas applies a uniform upward lifting force to the LED lamp bracket from the bottom, effectively reducing the adhesion between the bracket and the inner wall of the lower mold 1. Meanwhile, the ejector mechanism 3 acts on the support position of the LED lamp bracket, and through targeted pushing action, further breaks the adhesion between the bracket and the mold, and together pushes the LED lamp bracket to separate smoothly and completely from the inner wall of the lower mold 1, achieving efficient demolding. During the entire demolding process, the uniform action of the gas and the force exerted by the ejector mechanism 3 work together to avoid deformation of the bracket due to excessive local force, and also to prevent incomplete demolding due to insufficient force. After the LED lamp holder is successfully demolded, the device immediately enters the material preparation stage. At this time, the circular cover 9, connected to the lower end of pipe 12, gradually moves downward under the action of the external moving lifting mechanism until the adsorption plate 16 installed in the circular groove 13 at the lower end of the circular cover 9 is tightly attached to the upper surface of the demolded LED lamp holder. The attachment process of the adsorption plate 16 relies on the positioning function of the circular groove 13 to ensure that the adsorption plate 16 is aligned with the LED lamp holder and to avoid affecting the subsequent adsorption effect due to positional deviation.

[0041] After the adsorption plate 16 is attached to the LED light bracket, the pump body 5 switches its working mode from the previous inflation state to the air extraction state. At this time, the hose 26 connected to the upper end of the pump body 5 begins to play a negative pressure conduction role. The pump body 5 performs air extraction operation on the pipe 12 connected to it through the hose 26. The lower end of the pipe 12 passes through the top of the round cover 9 and extends into its inner cavity, and is connected to the round shell 18 inside the round cover 9. At the same time, the pipe 12 is also connected to the collection groove 22 on the round cover 9. Under the air extraction action of the pump body 5, the air in the round groove 13 at the lower end of the round cover 9 is drawn into the inner cavity of the round cover 9 through the adsorption hole 17 on the adsorption plate 16, and then passes through the round hole 23 on the round shell 18, the air guide pipe 14, and the collection groove 22 in sequence into the pipe 12, and is then extracted by the pump body 5 through the hose 26. As air is continuously expelled from the circular groove 13, a stable negative pressure environment is gradually formed inside the circular groove 13. Under the adsorption effect of the negative pressure, the LED light bracket is firmly adsorbed to the lower end of the adsorption plate 16, ensuring that it will not fall off or shift during subsequent movement. Finally, the connecting plate 7, which is connected to the rear end of the fixed plate 8 on pipe 12, begins to function as a connection and transmission device. Since the connecting plate 7 is connected to the external moving lifting mechanism, the power generated by the external moving lifting mechanism is transmitted to the fixed plate 8 through the connecting plate 7. The fixed plate 8 then drives pipe 12, which is fixed to it, and consequently, the circular cover 9, circular shell 18, adsorption plate 16, and the adsorbed LED lamp holder at the lower end of pipe 12 move synchronously. The external moving lifting mechanism can control the moving direction and lifting height of the connecting plate 7 according to the preset material path, ensuring that the LED lamp holder is smoothly and accurately transported to the designated position in the next production process. This achieves the effect of facilitating the unloading of LED lamp holders from the lower mold 1, and simultaneously facilitating the adsorption and transfer of the unloaded LED lamp holders.

[0042] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
