Description

Technical Field

[0001] This utility model relates to the field of LED production equipment technology, and in particular to an LED electroplating additive atomization spraying device. Background Technology

[0002] In the manufacturing process of LED components, surface electroplating is usually required to improve their performance and reliability. Before electroplating, uniformly spraying a layer of electroplating additive onto the component surface is a crucial pretreatment process. This significantly improves the uniformity, adhesion, and density of the subsequent electroplated layer, thus having a significant impact on the final photoelectric performance and lifespan of the LED product.

[0003] To ensure the quality of electroplating additive coatings, the pre-coating cleaning process is crucial. Any dust, oil, or other contaminants remaining on the surface of LED components can become potential sources of poor coating adhesion, leading to peeling and flaking during subsequent processes and resulting in quality defects. Therefore, thorough cleaning of the workpiece before coating is an essential step.

[0004] However, in current production practices, the three core processes of cleaning, spraying, and post-spraying drying and curing are often completed by independent equipment at different workstations. This station-based production model means that after completing one process, the workpiece needs to be manually or semi-automatically transferred before entering the next process. This not only lengthens the overall production cycle and reduces production efficiency, but more importantly, during the process of transferring the workpiece from the cleaning station to the spraying station, its freshly cleaned surface is easily exposed to the environment, posing a risk of secondary contamination by airborne dust and other contaminants. This significantly reduces the effectiveness of the pre-cleaning process.

[0005] This non-integrated workflow results in low automation of the entire process and makes it difficult to form a continuous, closed production environment. This makes it difficult to effectively guarantee the stability of process parameters and the consistency of product quality, while also increasing additional labor costs and the complexity of material transfer.

[0006] Therefore, this utility model proposes an LED electroplating additive atomization spraying device to overcome the shortcomings of the prior art. Summary of the Invention

[0007] To overcome the above shortcomings, this utility model provides an LED electroplating additive atomizing spraying device, which aims to improve the existing technology where the cleaning, spraying and drying processes of LED electroplating additive spraying are separated, resulting in low automation, low production efficiency and the risk of secondary pollution of workpieces during transportation.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: an LED electroplating additive atomizing spraying device, comprising: a body, a conveyor belt, an atomizing nozzle, a cleaning mechanism, and a drying mechanism.

[0009] The cleaning mechanism and the drying mechanism are respectively located upstream and downstream of the atomizing nozzle along the conveyor belt conveying direction, forming an integrated automated processing line.

[0010] The cleaning mechanism includes a motor, a cleaning roller, a first cylinder, a slider, and a chute. The motor is driven and connected to the cleaning roller, and the first cylinder is driven and connected to the slider. The slider is slidably disposed in the chute, and the cleaning roller is fixed on the slider, forming an execution unit capable of precise lifting, lowering, and rotating for cleaning. The drying mechanism includes a second cylinder, an adjusting plate, and a heating element. The second cylinder is driven and connected to the adjusting plate, and the position of the workpiece conveyed by the conveyor belt is adjusted by driving the adjusting plate to move.

[0011] Preferably, the cleaning mechanism further includes a mounting frame, on which the motor, the first cylinder, and the slide are all mounted.

[0012] Preferably, the cleaning mechanism further includes a cleaning fan disposed on one side of the cleaning roller to assist in cleaning debris.

[0013] Preferably, a rubber strip for flexibly contacting the workpiece is fixed on the adjustment plate.

[0014] Preferably, the drying mechanism further includes a fixing frame, on which the heating element is mounted.

[0015] Preferably, the drying mechanism further includes a control box, which is electrically connected to the second cylinder and the heating element respectively.

[0016] Preferably, it also includes a support frame, on which the atomizing nozzle is fixed.

[0017] This utility model has the following beneficial effects: 1. In this utility model, by integrating the cleaning mechanism, atomizing nozzle and drying mechanism into the same body, and using a conveyor belt to realize the automated continuous conveying of workpieces, the problems of separation of processes, low degree of automation and low production efficiency in the prior art are solved. The technical effect of integrated automated production of cleaning, spraying and drying is achieved, which significantly improves production efficiency and process stability.

[0018] 2. In this utility model, by setting up a cleaning roller driven by a motor and a structure that drives its lifting and lowering by a first cylinder, and cooperating with a cleaning fan to assist in cleaning, the problem of incomplete surface cleaning or residual debris on the workpiece before spraying in the prior art is solved, and the technical effect of efficient, uniform and automated cleaning of the workpiece surface is achieved, thereby improving the adhesion and quality of the subsequent electroplating additive coating.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-5 The present invention provides an embodiment of an LED electroplating additive atomizing spraying device, which aims to solve the problems of low automation, poor pre-spraying cleaning effect, and unstable post-spraying adhesion and curing quality caused by the separation of cleaning, spraying and drying processes in the existing LED component spraying process.

[0023] The LED electroplating additive atomizing spraying device includes a body 1, a conveyor belt 2 installed inside the body 1, and a cleaning mechanism 5, an atomizing nozzle 4, and a drying mechanism 6 arranged sequentially along the conveying direction of the conveyor belt 2. The atomizing nozzle 4 is fixed to the body 1 by a support frame 3. The cleaning mechanism 5 and the drying mechanism 6 respectively perform pre-spray cleaning and post-spray drying treatments on the workpieces. The conveyor belt 2 is used to realize the continuous conveying of the workpieces between the cleaning mechanism 5, the atomizing nozzle 4, and the drying mechanism 6.

[0024] The cleaning mechanism 5 includes a mounting frame 501, a motor 502, a cleaning roller 503, a first cylinder 504, a slider 505, a chute 506, and a cleaning fan 507. The mounting frame 501 is fixed to the body 1, providing a mounting base for each component of the cleaning mechanism 5. The motor 502, the first cylinder 504, and the chute 506 are all mounted on the mounting frame 501. The slider 505 is slidably disposed in the chute 506. The first cylinder 504 is driven and connected to the slider 505, driving the slider 505 to reciprocate along the guide direction of the chute 506. The cleaning roller 503 is fixed on the slider 505 to achieve synchronous lifting and lowering. The output shaft of the motor 502 is driven and connected to the cleaning roller 503, driving the cleaning roller 503 to rotate. The cleaning fan 507 is disposed on one side of the cleaning roller 503, assisting in cleaning debris.

[0025] The drying mechanism 6 includes a fixed frame 601, a control box 602, a second cylinder 603, an adjusting plate 604, a rubber strip 605, and a heating element 606. The fixed frame 601 is fixed to the machine body 1. The heating element 606 is installed on the fixed frame 601 and located above the conveying path of the conveyor belt 2. The second cylinder 603 is driven and connected to the adjusting plate 604 to drive the adjusting plate 604 to move and adjust the position of the workpiece. The rubber strip 605 for flexible contact with the workpiece is fixed on the adjusting plate 604. The control box 602 is electrically connected to the second cylinder 603 and the heating element 606 respectively to control the automated operation of the drying mechanism 6.

[0026] The slide 506 has a guide rail extending vertically. The slide 506 is fixedly connected to the inner wall of the mounting bracket 501 by bolts or welding. Its function is to provide precise guidance and limit for the reciprocating motion of the slider 505. At the same time, the slider 505 is provided with a sliding part that matches the shape and size of the guide rail of the slide 506. In the assembled state, the sliding part of the slider 505 slides in the guide rail of the slide 506, ensuring the high stability and anti-deflection ability of the slider 505 during the lifting process, thereby ensuring that the cleaning roller 503 fixed on the slider 505 can smoothly contact the workpiece surface.

[0027] For the power source driving the slider 505, this embodiment uses a first cylinder 504. The cylinder body of the first cylinder 504 is fixed on the mounting bracket 501, and the end of its piston rod is driven to connect to the slider 505. By controlling the extension and retraction of the first cylinder 504, the slider 505 can be driven to slide up and down along the slide groove 506. For the rotation power source of the cleaning roller 503, this embodiment uses a motor 502, which drives the cleaning roller 503 to rotate to wipe and clean the surface of the workpiece.

[0028] In order to provide a stable mounting base for the various components of the cleaning mechanism 5, the cleaning mechanism 5 also includes a mounting bracket 501, on which the motor 502, the first cylinder 504 and the slide 506 are all mounted.

[0029] In order to remove debris generated during the cleaning process in a timely manner to ensure the cleanliness of the workpiece surface, the cleaning mechanism 5 also includes a cleaning fan 507, which is located on one side of the cleaning roller 503 and is used to assist in cleaning debris.

[0030] In order to avoid damaging the workpiece surface and provide flexible contact and cushioning when adjusting the workpiece position, a rubber strip 605 is fixed on the adjusting plate 604.

[0031] In order to securely fix and support the heating element 606 of the drying mechanism 6, the drying mechanism 6 also includes a fixing frame 601, on which the heating element 606 is mounted.

[0032] In order to achieve automated and coordinated control of the various actuators of the drying mechanism 6, the drying mechanism 6 also includes a control box 602, which is electrically connected to the second cylinder 603 and the heating element 606 respectively.

[0033] To ensure the stability and precision of the atomizing nozzle 4 position and thus guarantee the uniformity of the spraying quality, the device also includes a support frame 3, on which the atomizing nozzle 4 is fixed.

[0034] Working principle: First, the LED workpiece to be processed is placed on the conveyor belt 2. The conveyor belt 2 starts running and sends the workpiece into the machine body 1, first reaching the bottom of the cleaning mechanism 5. At this time, the first cylinder 504 is activated, driving the slider 505 to slide downward in the slide groove 506, thereby driving the cleaning roller 503 fixed on the slider 505 to descend and contact the surface of the workpiece. At the same time, the motor 502 drives the cleaning roller 503 to rotate at high speed to wipe and clean the surface of the workpiece. The cleaning fan 507 works synchronously to blow away the debris generated during the cleaning process, completing the pretreatment process before spraying.

[0035] Next, the conveyor belt 2 continues to run, transporting the cleaned workpiece to below the atomizing nozzle 4. The atomizing nozzle 4, which is stably supported by the support frame 3, is activated, atomizing the electroplating additive and spraying it evenly onto the surface of the workpiece. After spraying, the conveyor belt 2 continues to transport the workpiece to the drying mechanism 6 area. At this time, the control box 602 controls the second cylinder 603 to drive the adjusting plate 604 to accurately position the workpiece. The rubber strip 605 on the adjusting plate 604 protects the workpiece during the positioning process. After positioning, the heating tube 606 is energized to heat up and dry the sprayed workpiece, allowing the additive coating to quickly cure and adhere firmly.

[0036] By coordinating the cleaning mechanism 5, the atomizing nozzle 4, and the drying mechanism 6 along the conveyor belt 2, this invention solves the problems of separation of processes and low automation in the prior art. Through structured automatic cleaning and drying, it significantly improves the final coating quality and production efficiency.
