Description

Technical Field

[0001] This invention belongs to the technical field of lighting production equipment, and specifically relates to a production equipment for LED lamps. Background Technology

[0002] LED lights are solid-state semiconductor devices that can convert electrical energy into visible light. With the application of LED lights in various light fields such as displays and signal lights, they have generated good economic and social benefits. In addition to the common LED strip lights, LED fluorescent lights, which are similar to fluorescent lamps, have also emerged, and their performance is better than that of ordinary fluorescent lamps.

[0003] LED fluorescent lamps, in their operating environment, require higher protection strength compared to LED strip lamps. Therefore, these LED lamps have the LED chips mounted on a base plate and then installed and protected by an external lampshade. To further improve the protection of the LED chips by the lampshade, such as preventing water droplets from forming on the outside of the lampshade due to temperature differences and seeping into the lampshade or causing lampshade aging, the outside of the lampshade is often coated with paint. With the development of large-scale production, traditional manual spraying or single machine spraying methods can no longer meet the needs of high-efficiency and high-quality production. Summary of the Invention

[0004] The purpose of this invention is to provide an LED lamp production equipment to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0012] The pressure assembly includes a second spring and a limiting plate. The limiting plate is fixedly connected to the upright and located between the friction wheel and the fixed plate. The second spring is sleeved on the upright and located between the limiting plate and the fixed plate.

[0013] The synchronization component includes an arc-shaped plate, an arc-shaped guide rod, a synchronization block, a force-bearing arm, a thrust arm, and a third spring.

[0026] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Example 1:

[0028] like Figure 1-5 As shown, an LED lamp production equipment includes a control panel, a base 1 and an external liquid supply mechanism. The upper end of the base 1 is provided with a platform, and the platform is evenly provided with a number of mounting mechanisms. The base 1 is also provided with a spraying mechanism that matches the mounting mechanisms.

[0029] The mounting mechanism includes a vertical rod 3, a slider 31, a pressure component, and a guide wheel component. The platform has several grooves 32 that match the mounting mechanism. The slider 31 is slidably disposed in the grooves 32 and is provided with a reset component. The guide wheel component is disposed at the lower end of the slider 31 and matches the platform. The vertical rod 3 is rotatably connected to the slider 31 and passes through the guide wheel component. The pressure component is disposed at the lower end of the guide wheel component and matches the vertical rod 3.

[0030] The spraying mechanism includes a bracket 4, an arc-shaped spray nozzle 41, a crash stopper, and a synchronization component. The synchronization component is located on the platform and matches the guide wheel assembly. The bracket 4 is connected to the synchronization component, the arc-shaped spray nozzle 41 is connected to the bracket 4, and the crash stopper is connected to the lower side of the bracket 4 and matches the upright 3.

[0031] A material unloading assembly is located on the upper side of the platform, behind the spraying mechanism, relative to the rotation direction of the platform.

[0032] When the lampshade is coated, the operator or external mechanical claw is positioned on the side of the device relative to the coating mechanism. This side is the material loading point. At this time, the operator or external mechanical claw loads the lampshade to be processed onto the upper end of the support rod 3 of the mounting mechanism. The upper end of the support rod 3 is connected to a positioning head by a thread. The structure of the positioning head is the same as that of the lampshade to be processed. This can improve the stability of the lampshade when it is placed. Then, by rotating the platform, several mounting mechanisms on the platform will be rotated in a cycle. This can improve the continuity of the device's operation and processing.

[0033] As the platform continues to transport the lampshade, it will move synchronously and gradually approach the spraying mechanism. At this time, the guide wheel assembly of the mounting mechanism will be gradually coordinated with the synchronous assembly of the spraying mechanism by the action of the platform, so that the bracket 4 and the arc-shaped spray pipe 41 in the spraying mechanism move synchronously with the mounting mechanism. In this way, during the movement of the mounting mechanism, the spraying mechanism will always remain in correspondence with the mounting mechanism. During this process, when the spraying mechanism moves, the control panel controls the external liquid supply mechanism to deliver paint and inject it into the arc-shaped spray pipe 41 through the hose. At this time, several nozzles on the arc-shaped spray pipe 41 spray the paint onto the surface of the lampshade. The specific control switch method can be determined by the contact sensor or displacement sensor.

[0034] Once the guide wheel assembly of the mounting mechanism matches the synchronization assembly, the spraying mechanism will move synchronously with the mounting mechanism to spray paint. Simultaneously, because the upright 3 and the slider 31 are rotatably connected, the upright 3 will rotate during this process under the action of the guide wheel assembly, causing the lampshade to rotate relative to the spraying mechanism. At this time, the lampshade will also rotate on its own axis while moving around the platform, effectively and evenly spraying the surface of the lampshade. This continues until the guide wheel assembly of the mounting mechanism disengages from the synchronization assembly, at which point the spraying mechanism resets. The mounting mechanism then continues to move to the unloading assembly, where the lampshade is automatically unloaded to complete the spraying process. This cycle repeats, resulting in high and continuous production efficiency, and more uniform and effective spraying of the lampshade, better meeting the needs of high-efficiency and high-quality production.

[0035] The platform includes a circular plate 2, a cam ring 21, and an arc-shaped friction ring 22. A motor is fixedly installed at the upper center of the base 1. The circular plate 2 is connected to the output shaft of the motor. The cam ring 21 is located between the circular plate 2 and the base 1 and is concentrically arranged with the circular plate 2. The protruding part of the cam ring 21 matches the spraying mechanism. The arc-shaped friction ring 22 is located on the protruding part of the cam ring 21 and matches the guide wheel assembly. The upper end of the base 1 has an arc-shaped groove 23 that matches the unloading assembly. The circular plate 2 serves to install the mounting mechanism and cooperate with the motor to achieve continuous processing. The cam ring 21 and the arc-shaped friction ring 22 can cooperate with the guide wheel assembly to allow the mounting mechanism to move on the circular plate 2, thereby matching the synchronous components of the spraying mechanism and achieving the effect of connection and disconnection.

[0036] The guide wheel assembly includes a fixed plate 5, a pulley 51, and a friction wheel 52. The fixed plate 5 is fixedly connected to the lower end of the slider 31 and sleeved on the upright 3. The pulley 51 is rotatably located at the end of the fixed plate 5 and abuts against the cam ring 21. The reset component is the first spring 53. The friction wheel 52 is fixedly located on the lower side of the upright 3 and matches the arc-shaped friction ring 22. The fixed plate 5 serves to connect with the slider 31. The pulley 51 can always maintain a close connection with the cam ring 21 under the pushing action of the reset component, so that the mounting mechanism can be displaced by the action of the cam ring 21. When the friction wheel 52 is in contact with the arc-shaped friction ring 22, the friction force forces the upright 3 to rotate, thereby changing the position of the lampshade and achieving the desired spraying effect.

[0037] The pressure assembly includes a second spring 54 and a limiting plate 55. The limiting plate 55 is fixedly connected to the upright 3 and located between the friction wheel 52 and the fixed plate 5. The second spring 54 is sleeved on the upright 3 and located between the limiting plate 55 and the fixed plate 5. The cooperation between the second spring 54 and the limiting plate 55 can always keep the upright 3 under downward force, thereby ensuring the stability of the upright 3 and meeting the state requirements during material feeding.

[0038] Example 2:

[0039] like Figure 2-5 As shown, in a further improvement based on Embodiment 1, the synchronization component includes an arc-shaped plate 6, an arc-shaped guide rod 61, a synchronization block 62, a force-bearing arm 63, a thrust arm 64, and a third spring 65. The number of thrust arms 64 corresponds to the number of mounting mechanisms and is mounted on the fixed plate 5. The arc-shaped plate 6 has an arc-shaped groove 66, and the upper end surface of the arc-shaped plate 6 and the end facing the platform are both connected to the arc-shaped groove 66. The arc-shaped guide rod 61 is fixedly mounted in the arc-shaped groove 66. The synchronization block 62 is located in the arc-shaped groove 66 and is slidably connected to the arc-shaped guide rod 61. The force-bearing arm 63 is connected to the synchronization block 62. The third spring 65 is fitted onto the arc-shaped guide rod 61 and pushes the synchronizing block 62 to move away from the unloading assembly. The bracket 4 is fixedly connected to the upper end of the synchronizing block 62. The bracket 4 includes vertical rods 7 and multi-stage elastic telescopic rods 71 ​​that are perpendicular to each other. The arc-shaped nozzle 41 is connected to the output shaft of the multi-stage elastic telescopic rods 71. The anti-collision device includes an extension rod 72 and an inclined plate 73. The extension rod 72 is fixedly connected to the lower side of the output shaft of the multi-stage elastic telescopic rods 71 ​​and is vertically distributed. The inclined plate 73 is connected to the other end of the extension rod 72 and is matched with the upright rod 3.

[0040] To ensure the effective spraying effect of the spraying assembly, when the mounting mechanism moves and coordinates with the synchronization assembly, the thrust arm 64 connected to the guide wheel assembly will be pushed towards the spraying mechanism by the arc friction ring 22. At this time, the thrust arm 64 will gradually match the force arm 63 and push it. The force arm 63, when pushed, will drive the synchronization block 62 to slide along the arc guide rod 61 and the arc groove 66, so that the bracket 4 and the arc nozzle 41 connected to the synchronization block 62 can always correspond to the position of the lamp cover during the spraying process. The anti-collision device can, when the mounting mechanism is pushed close to the spraying mechanism by the cam ring 21, collide and squeeze the inclined plate 73 during the movement of the upright 3 through the cooperation of the upright 3 and the inclined plate 73, thereby applying a thrust to the multi-stage elastic telescopic rod 71. Since the multi-stage elastic telescopic rod 71 can extend and retract and remain extended in a stationary state, it can, on the one hand, work with the anti-collision device to adjust the position of the arc nozzle 41 in real time to avoid collision with the lamp cover, and on the other hand, automatically reset to maintain the state that meets the spraying requirements.

[0041] As the mounting mechanism continues to move, the guide wheel assembly will gradually move away from the spraying mechanism until it is completely separated from the thrust arm 64. At this time, the third spring 65 will extend and retract to push the synchronizing block 62, thereby resetting the synchronizing block 62 to prepare for the next spraying. During the resetting process, the synchronizing block 62 will collide with the inner wall of the arc groove 66. The vibration generated by the collision will cause the paint residue on the arc nozzle 41 to fall off, preventing the paint residue from causing the arc nozzle 41 to gradually become blocked, thus reducing the maintenance. Correspondingly, the guide wheel assembly of the mounting mechanism will also generate a slight vibration when it is separated from the arc friction ring 22. This can knock off the paint residue on the edge of the lampshade, which is more conducive to subsequent processing needs and prevents the paint from becoming granular after drying, affecting the appearance of the lampshade.

[0042] Example 3:

[0043] like Figure 1 As shown, in a further improvement based on Embodiment 1, the unloading assembly includes an arc-shaped unloading plate 8 and a roller conveyor 81 connected to the external support 4. The arc-shaped unloading plate 8 and the roller conveyor 81 are integrated. An arc-shaped movable groove 82 matching the shape of the upright 3 and the circumferential motion trajectory is opened in the middle of the arc-shaped unloading plate 8. The position of the arc-shaped groove 23 corresponds to the position of the arc-shaped movable groove 82.

[0044] To improve processing efficiency and further enhance continuity, after the lampshade painting process is completed, it will continue to be driven by the platform. Due to the downward push of the pressure component, when the upright 3 moves to the position of the arc-shaped groove 23, the upright 3 will gradually move downward, thereby reducing the height of the upright 3. Before this, the upright 3 has already slid into the arc-shaped movable groove 82 of the arc-shaped unloading plate 8. In this way, while the upright 3 is in a moving state, the downward movement will cause the lampshade to detach from the connection with the upright 3 support 4 and be placed flat on the arc-shaped unloading plate 8. Finally, the lampshade can be automatically delivered with the help of the roller conveyor 81. This can avoid the coating being damaged due to the transfer of the lampshade through an external mechanism after the painting is completed, and reduce the setting of external transfer mechanisms, thus automatically realizing the unloading.

[0045] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
