Description

Technical Field

[0001] This utility model relates to the field of automated production technology, specifically an automatic screw-on mechanism for lampshades. Background Technology

[0002] Chinese utility model patent CN202320808500.2 discloses a plug-in lamp fixture. One end of the fixture, near the lamp holder, is coaxially connected to a first annular mounting base. The diameter of the first mounting base is larger than that of the lampshade, and an externally threaded tube is coaxially connected to its side away from the lampshade. The inner wall of the lamp holder, near the lampshade, has an internal thread that mates with the externally threaded tube. The lampshade and lamp holder are assembled by the threaded engagement between the externally threaded tube and the internal thread of the lamp holder. However, existing technologies typically assemble lampshades and lamp holders manually. Workers hold the lampshade, align it with the lamp holder, and then rotate it onto the lamp holder. This operation is not only inefficient and costly, but also prone to damage. Since the lampshade is made of transparent glass, excessive rotational force can cause breakage, while insufficient force fails to achieve effective assembly. Furthermore, workers are susceptible to injury during the process. Therefore, further improvements are necessary. Utility Model Content

[0003] The present invention aims to provide an automatic screw-on mechanism for lampshades to overcome the shortcomings of the prior art.

[0004] An automatic screw-on mechanism for lampshades, designed for this purpose, includes an assembly workbench with a component positioning seat for placing the lamp housing. A screw-on device is located on the outer side of the assembly workbench. The screw-on device includes a screw-on stand, a screw-on driver, a screw-on clamping driver, and a screw-on clamping arm for clamping or releasing the lampshade. The screw-on driver is mounted on the screw-on stand and is driven to the screw-on clamping driver. The screw-on clamping driver is driven to the screw-on clamping arm. The screw-on clamping arm clamps or releases the lampshade via the drive of the screw-on clamping driver, and rotates on the screw-on stand while clamping the lampshade, driven by the screw-on driver, to automatically screw the lampshade onto the lamp housing.

[0005] The screw-on stand is fixedly installed on the outside of the assembly workbench. It is also equipped with a screw-on longitudinal sliding seat, a screw-on longitudinal sliding driver, a screw-on lead screw, and a screw-on longitudinal sliding component. The screw-on longitudinal sliding seat is longitudinally fixed on the screw-on stand. The screw-on longitudinal sliding driver is installed on the screw-on longitudinal sliding seat and is driven to connect with the screw-on lead screw. The screw-on lead screw rotates longitudinally on the screw-on longitudinal sliding seat and is driven to connect with the screw-on longitudinal sliding component. The screw-on driver or the screw-on clamping driver is longitudinally fixed on the screw-on longitudinal sliding component.

[0006] The swivel joint longitudinal sliding base is also longitudinally fixed with a swivel joint longitudinal sliding guide rail, and the swivel joint longitudinal sliding component is fixedly provided with a swivel joint longitudinal sliding slider, which guides the sliding component to slide on the swivel joint longitudinal sliding guide rail.

[0007] The rotary longitudinal transfer seat is provided with a longitudinal transfer seat cavity. The rotary lead screw, the rotary longitudinal transfer member, the rotary longitudinal transfer guide rail, and the rotary longitudinal transfer slider are all located in the longitudinal transfer seat cavity. A cavity cover plate is also fixedly provided on the rotary longitudinal transfer seat. The cavity cover plate covers the longitudinal transfer seat cavity. The rotary longitudinal transfer member extends at least partially out of the longitudinal transfer seat cavity and is fixedly connected to a rotary drive seat.

[0008] The rotary longitudinal transfer driver is a drive motor and is longitudinally fixed on the top of the rotary longitudinal transfer seat. The drive end of the rotary longitudinal transfer driver extends into the cavity of the longitudinal transfer seat and is drivenly connected to the rotary lead screw.

[0009] The rotary drive is a drive motor and is longitudinally fixed on the top of the rotary drive base. The rotary drive is also driven by a rotary reducer and is driven by the rotary clamping drive through the rotary reducer.

[0010] The rotary clamping driver is a drive cylinder, and the rotary reducer is longitudinally fixed to the bottom of the rotary drive seat and is drivenly connected to the rotary clamping driver.

[0011] The screw-on clamping arm is disposed on the drive end of the screw-on clamping driver, and a screw-on clamping part is provided corresponding to the outer contour of the lampshade.

[0012] The accessory positioning seat is provided with a lamp housing positioning groove, and the lamp housing is positioned on the lamp housing positioning groove.

[0013] A lamp housing guide edge is provided at the opening above the lamp housing positioning groove.

[0014] This utility model, through structural improvements, utilizes the positioning function of the accessory positioning seat to enable the lamp housing to be positioned and placed. Furthermore, the driving action of the rotary clamping driver allows the rotary clamping arm to clamp or release the lamp cover. When the rotary clamping arm clamps the lamp cover, the driving action of the rotary driver allows the clamped lamp cover to rotate automatically and be assembled onto the lamp housing. This effectively reduces a series of problems caused by manual operation, such as low production efficiency, high costs, and personnel injuries. Moreover, the clamping force and rotational force of the rotary clamping driver are small and constant, making the rotational force between the lamp cover and the lamp housing more reasonable and uniform, ensuring effective assembly while preventing damage, thus demonstrating strong practicality.

[0019] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] See Figures 1-4 The automatic screw-on mechanism for lampshades includes an assembly workbench X, on which a component positioning seat 200 for placing lamp housing 2 is provided. A screw-on device is provided on the outside of the assembly workbench X. The screw-on device includes a screw-on stand E1, a screw-on driver E2, a screw-on clamping driver E3, and a screw-on clamping arm E4 for clamping or releasing the lampshade 4. The screw-on driver E2 is mounted on the screw-on stand E1 and is driven to be connected to the screw-on clamping driver E3. The screw-on clamping driver E3 is driven to be connected to the screw-on clamping arm E4. The screw-on clamping arm E4 clamps or releases the lampshade 4 by the drive of the screw-on clamping driver E3. When clamping the lampshade 4, it rotates on the screw-on stand E1 by the drive of the screw-on driver E2 to automatically screw the lampshade 4 onto the lamp housing 2.

[0022] This mechanism utilizes the positioning function of the accessory positioning seat 200 to enable the lamp housing 2 to be positioned and placed. The driving action of the screw-on clamping driver E3 enables the screw-on clamping arm E4 to clamp or release the lamp cover 4. When the screw-on clamping arm E4 clamps the lamp cover 4, the driving action of the screw-on driver E2 allows the clamped lamp cover 4 to automatically rotate and assemble onto the lamp housing 2. This effectively reduces a series of problems caused by manual operation, such as low production efficiency, high costs, and personnel injuries. Moreover, the clamping force of the screw-on clamping driver E3 and the rotational force of the screw-on driver E2 are small and constant, making the screw-on force between the lamp cover 4 and the lamp housing 2 more reasonable and uniform. This ensures effective assembly while preventing damage, making it highly practical.

[0023] The swivel joint stand E1 is fixedly installed on the outside of the assembly workbench X. It is also equipped with a swivel joint longitudinal sliding seat E5, a swivel joint longitudinal sliding driver E6, a swivel joint screw E7, and a swivel joint longitudinal sliding component E8. The swivel joint longitudinal sliding seat E5 is fixed longitudinally on the swivel joint stand E1. The swivel joint longitudinal sliding driver E6 is installed on the swivel joint longitudinal sliding seat E5 and is driven to connect with the swivel joint screw E7. The swivel joint screw E7 rotates longitudinally on the swivel joint longitudinal sliding seat E5 under the drive of the swivel joint longitudinal sliding driver E6 and is driven to connect with the swivel joint longitudinal sliding component E8. The swivel joint driver E2 or the swivel joint clamping driver E3 is fixed longitudinally on the swivel joint longitudinal sliding component E8.

[0024] In this embodiment, when the rotary longitudinal movement driver E6 is working, it drives the rotary lead screw E7 to rotate on the rotary longitudinal movement seat E5. When the rotary lead screw E7 rotates, it drives the rotary longitudinal movement component E8 to perform longitudinal reciprocating movement on the rotary longitudinal movement seat E5, so that the rotary driver E2, the rotary clamping driver E3, and the rotary clamping arm E4 can perform longitudinal reciprocating movement together. The rotary clamping arm E4 can then move the clamped lampshade 4 toward the lamp housing 2.

[0025] The swivel joint longitudinal sliding seat E5 is also longitudinally fixed with a swivel joint longitudinal sliding guide rail E9, and the swivel joint longitudinal sliding component E8 is fixedly provided with a swivel joint longitudinal sliding slider E10, which guides and slides on the swivel joint longitudinal sliding guide rail E9.

[0026] In this embodiment, by utilizing the cooperation of the rotary longitudinal sliding slider E10 and the rotary longitudinal guide rail E9, the rotary longitudinal sliding component E8 can stably reciprocate longitudinally on the rotary longitudinal sliding seat E5, thereby ensuring that the rotary driver E2, the rotary clamping driver E3, and the rotary clamping arm E4 can achieve stable longitudinal reciprocating movement.

[0027] The longitudinal sliding seat E5 is provided with a longitudinal sliding seat cavity E5.1. The screw rod E7, the longitudinal sliding component E8, the longitudinal sliding guide rail E9, and the longitudinal sliding slider E10 are all located in the longitudinal sliding seat cavity E5.1. A cavity cover plate E11 is also fixedly installed on the longitudinal sliding seat E5. The cavity cover plate E11 covers the longitudinal sliding seat cavity E5.1. The longitudinal sliding component E8 extends at least partially out of the longitudinal sliding seat cavity E5.1 and is fixedly connected to the screw drive seat E12.

[0028] In this embodiment, the longitudinal sliding seat cavity E5.1 and cavity cover plate E11 can effectively shield and protect the screw rod E7, the longitudinal sliding component E8, the longitudinal sliding guide rail E9, and the longitudinal sliding slider E10 to prevent foreign objects from contacting the above-mentioned parts and causing an impact, thereby further improving the longitudinal reciprocating stability of the screw drive E2, the screw clamp drive E3, and the screw clamp arm E4.

[0029] The rotary longitudinal transfer driver E6 is a drive motor and is longitudinally fixed on the top of the rotary longitudinal transfer seat E5. The drive end of the rotary longitudinal transfer driver E6 extends into the cavity E5.1 of the longitudinal transfer seat and is driven by the rotary lead screw E7.

[0030] The rotary drive E2 is a drive motor and is longitudinally fixed on the top of the rotary drive base E12. The rotary drive E2 is also connected to a rotary reducer E13, and is connected to the rotary clamping drive E3 through the rotary reducer E13.

[0031] The rotary clamping driver E3 is a drive cylinder, and the rotary reducer E13 is longitudinally fixed to the bottom of the rotary drive seat E12 and is driven by the rotary clamping driver E3.

[0032] In this embodiment, the rotary drive E2 and rotary reducer E13 are respectively located at the top and bottom of the rotary drive base E12, which can improve the assembly convenience and stability of the rotary drive E2 and rotary reducer E13. At the same time, the rotary drive E2, rotary reducer E13 and rotary clamping drive E3 are mutually driven and connected, and form a longitudinally coaxial arrangement, which not only facilitates power output and reduces transmission loss, but also reduces space occupancy.

[0033] The screw-on clamping arm E4 is mounted on the drive end of the screw-on clamping driver E3, and a screw-on clamping part is provided corresponding to the outer contour of the lamp cover 4.

[0034] In this embodiment, since the screw-on clamping arm E4 is provided with a screw-on clamping part corresponding to the outer contour of the lamp cover 4, the screw-on clamping arm E4 can effectively clamp the lamp cover 4 through the screw-on clamping part, thereby improving the clamping stability of the lamp cover 4. The shape of the screw-on clamping part is an arc-shaped groove. In addition, the screw-on clamping part can also be provided with a flexible part, so that the screw-on clamping part acts on the lamp cover 4 through the flexible part, which can further prevent the lamp cover 4 from breaking or being damaged.

[0035] The accessory positioning seat 200 is provided with a lamp housing positioning groove 301, and the lamp housing 2 is positioned and placed on the lamp housing positioning groove 301.

[0036] In this embodiment, the positioning function of the lamp housing positioning groove 301 can be used to preposition the lamp housing 2 on the accessory positioning seat 200, thereby improving the positioning stability of the lamp housing 2 and avoiding the problem of the lamp housing 2 rotating when the lamp cover 4 and the lamp housing 2 are screwed together.

[0037] A lamp housing guide edge 302 is provided at the opening above the lamp housing positioning groove 301.

[0038] In this embodiment, the lamp housing 2 can also be guided and positioned on the lamp housing positioning groove 301 by the lamp housing guide edge 302, so as to improve the convenience and accuracy of positioning the lamp housing 2.

[0039] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
