Description

Technical Field

[0001] This utility model relates to the field of LED packaging technology, specifically to an LED dispensing needle cleaning fixture. Background Technology

[0002] Protecting the dispensing needles is crucial in the LED encapsulation dispensing process. Due to the high precision of the dispensing needles, their cost is a significant factor in production, and most dispensing needles need to be reused. This reuse involves cleaning the needles. The typical cleaning process involves removing the needles from the valve body, placing them on a cleaning carrier, and then cleaning them in an ultrasonic cleaner. However, haphazard placement of the needles during cleaning can cause deformation, surface wear, and tip breakage due to impact and friction. This directly affects the stability of the dispensing process, leading to poor dispensing quality and impacting production efficiency and yield. Furthermore, structural damage to the needles necessitates replacement with new needles, shortening their lifespan and increasing manufacturing costs. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an LED dispensing needle cleaning fixture, which solves the technical problem of easy damage during the cleaning of dispensing needles.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an LED dispensing needle cleaning fixture, including a carrier plate, the carrier plate having a plurality of fixed slots arranged in an array for placing dispensing needles, the fixed slots containing dispensing needles, two symmetrically arranged fixing members fixedly attached to the carrier plate, the two fixing members having limiting members pressed onto them for fixing the dispensing needles, and support columns fixedly attached to the four corners of the bottom of the carrier plate.

[0005] The limiting component includes a pressure plate covering the dispensing needle head. The pressure plate has a through hole at the position corresponding to the dispensing needle head. Notches are provided at both ends of the pressure plate near the fixing component. Support feet are fixed at the four corners of the pressure plate surface.

[0022] 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.

[0023] LED dispensing needles are tools used for dispensing in the LED production process. They are usually installed on the dispensing valve of the dispensing machine and, under the action of the dispensing controller, accurately apply glue to LED chips, brackets, or other related components.

[0024] Due to the inherent technical limitations of existing technologies, such as the risk of damage during cleaning, please refer to... Figures 1-5 This embodiment provides an LED dispensing needle cleaning fixture. By placing the dispensing needles on the cleaning fixture, the damage to the needle mechanism caused by shaking or collision during storage, operation, and cleaning is mitigated. The fixture includes a carrier plate 1 with multiple arrayed fixing slots 101 for placing the dispensing needles. The fixing slots 101 hold the dispensing needles. Two symmetrically arranged fixing members 2 are fixed to the carrier plate 1, and the two fixing members 2 are pressed with limiting devices for fixing the dispensing needles. The support column 5 is fixed at each of the four corners of the bottom of the carrier plate 1 and the positioning component 3. The dispensing needle is fixed by the fixing groove 101 on the carrier plate 1 to prevent it from shaking, falling or colliding during storage, operation and cleaning, thereby reducing damage to the dispensing needle and improving its service life. The limiting component 3 can be used to fix the dispensing needle after it is placed, so that it is more stable during storage, operation and cleaning. The support column 5 can be used to support the carrier plate 1 as a whole, so that there is a certain space between the bottom of the carrier plate 1 and the bottom of the inner cavity of the cleaning equipment, which can improve the cleaning effect.

[0025] While placing the dispensing needle on carrier plate 1 reduces the risk of collisions to some extent, the needle is not fixed in place, making it prone to falling and being damaged during handling and cleaning. For this issue, please refer to [link / reference needed]. Figure 4 The limiting component 3 includes a pressure plate 301 covering the dispensing needle. The pressure plate 301 has a through hole 3011 at the position corresponding to the dispensing needle. The pressure plate 301 has notches 3012 at both ends near the fixing component 2. Support legs 302 are fixed at the four corners of the surface of the pressure plate 301, and the length of the support legs 302 is greater than the head length of the dispensing needle. The through hole 3011 on the pressure plate 301 can fix the needle without affecting the cleaning solvent's cleaning of the needle. The notch 3012 is designed to facilitate the installation of the pressure plate 301 and the fixing component 2. Under the action of the support legs 302, the whole can also be used as a bracket to facilitate the storage of the dispensing needle.

[0026] When the limiting component 3 is placed on multiple dispensing needles, although it can hold the dispensing needles down by its own weight, instability still exists. For this issue, please refer to... Figure 4 The fixing component 2 includes a fixing post 201 fixed to the surface of the carrier plate 1. A rotating ring 202 is rotatably connected to the outer wall of the fixing post 201 near the top. An "L"-shaped pressure block 203 is fixed on the outer wall of the rotating ring 202. Since the fixing post 201 is directly connected to the carrier plate 1, when the pressure plate 301 presses on the dispensing needle, the fixing post 201 can restrict the movement of the pressure plate 301 under the action of the notch 3012 on the pressure plate 301. At the same time, by rotating the pressure block 203, the pressure block 203 can press the pressure plate 301, thereby achieving the purpose of fixing the pressure plate 301 and thus maintaining the stability of the dispensing needle.

[0027] Existing cleaning carriers may not allow the cleaning solvent to fully soak the inside of the needle during cleaning, resulting in incomplete removal of glue impurities. To address this issue, the bottom of the fixing groove 101 has a hollow structure, which allows the cleaning solvent to soak into the inside of the needle during cleaning, effectively removing glue impurities and improving the cleaning effect.

[0028] Existing cleaning carriers are inconvenient to handle during transportation and transfer. To address this issue, two symmetrically arranged handles 4 are fixed on the carrier plate 1 to facilitate the handling of the cleaning carrier during transportation and transfer, thereby improving operational convenience.

[0029] Furthermore, rubber pads 6 are fixed at the four corners of the side wall of the carrier plate 1; these pads can buffer the carrier plate 1 when it is placed, reducing the damage to the carrier plate 1 and the dispensing needle caused by collisions.

[0030] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
