Description

Technical Field

[0001] The utility model relates to the technical field of cleaning dispensing needles, in particular to a movable needle cleaning liquid spray barrel. Background Art

[0002] In the production process of liquid crystal display modules, dispensing is required to coat and encapsulate each component. Specifically, in order to protect the photosensitive components from being contaminated by dust ions, improve production quality, and prevent dust particles generated during long-term use, so as not to affect the final imaging; a dust capture process is added to the front-end packaging process, and the dust-proof glue is evenly applied to the electronic components around the filter above the photosensitive components to prevent dust. In this way, the dust-proof glue can absorb dust, thereby ensuring that dust does not move to the filter; but the dust-proof glue is a room temperature glue with high volatility, high fluidity and high viscosity. During the coating process, the glue is easy to adhere to the needle position to form a high-viscosity ball, which causes the needle to be clogged and causes abnormal dispensing.

[0003] A patent search revealed that a Chinese patent with publication number CN221413739U discloses a glue coating device, which includes a glue dispensing component, which includes a glue dispensing needle, which has a needle head for applying glue to the parts to be glued; a cleaning component, which is arranged on one side of the glue dispensing component, and the cleaning component forms a cleaning chamber with an opening, and the cleaning chamber is used to hold a cleaning agent; and a driving component, which is arranged on one side of the glue dispensing component and is connected to the driving connection of the glue dispensing component, and is used to drive the glue dispensing needle to move close to the cleaning component so that the needle head of the glue dispensing needle is immersed in the cleaning agent in the cleaning chamber, or drive the glue dispensing needle away from the cleaning component to apply glue to the parts to be glued, thereby solving the problem that the needle head of the glue dispensing needle in the existing device is easily clogged.

[0004] The inventors found that the existing needle cleaning device still has the following problems, such as: the needle of the dispensing needle is immersed in a cleaning box containing cleaning agent for cleaning. After long-term use, a large amount of dissolved glue will accumulate inside the cleaning box, thereby affecting the cleaning effect of the needle. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-5 The movable needle cleaning liquid spray barrel of this embodiment includes a barrel body 1, a barrel cover 2, a nozzle 3, a supply pipe 4, a booster 5 and a solution reflux pipe 6. The barrel body 1 is used to store cleaning agent, and a barrel cover 2 is provided at the upper end of the barrel body 1; at least one group of nozzles 3 is provided (two groups are provided in this embodiment), and a supply pipe 4 is provided between the nozzle 3 and the barrel body 1, and the cleaning agent inside the barrel body 1 is transported to the nozzle 3 through the booster 5 provided on the supply pipe 4; the nozzle 3 is connected to the barrel cover 2 through the solution reflux pipe 6, and the cleaning agent inside the nozzle 3 is refluxed to the interior of the barrel body 1 through the solution reflux pipe 6.

[0030] The utility model can realize the function of spraying cleaning agent to the needle through the mutual cooperation between the barrel body 1, the nozzle 3, the supply pipe 4, and the solution reflux pipe 6, thereby avoiding the needle of the dispensing needle from being blocked. This arrangement can ensure that the cleaning agent sprayed to the needle is always clean, thereby ensuring the cleaning effect of the needle.

[0031] like Figure 1 As shown, a nozzle cover 7 is provided at the upper end of the nozzle 3 . The provision of the nozzle cover 7 can reduce the volatilization of the cleaning agent and prevent pollutants from entering the interior of the nozzle 3 .

[0032] like Figure 4 As shown, the supercharger 5 is provided with an air pipe 8 , and the air pipe 8 is connected to an air supply device, which is used to provide a stable air source to the supercharger 5 .

[0033] like Figure 1 As shown, a solution adding port 9 is fixedly provided on one side of the barrel body 1 , and the solution adding port 9 is funnel-shaped, which is convenient for adding cleaning agent to the solution adding port 9 .

[0034] like Figure 3 As shown, a solution observation tube 10 is fixedly provided on the outer side of the barrel body 1. The solution observation tube 10 is made of transparent material, which is convenient for observing the capacity of the cleaning agent inside the barrel body 1.

[0035] like Figure 3 As shown, a solution detector 11 is fixedly provided at the bottom of the solution observation tube 10. The solution detector 11 is used to monitor the capacity of the cleaning agent inside the barrel body 1 in real time. When the capacity of the cleaning agent inside the barrel body 1 is too low, an alarm will be triggered to prompt the operator to add cleaning agent in time.

[0036] like Figure 1 As shown, the barrel body 1 is installed on the barrel bottom leakage receiving plate 12, and the nozzle 3 is installed on the nozzle leakage receiving plate 13. The upper ends of the barrel bottom leakage receiving plate 12 and the nozzle leakage receiving plate 13 are both provided with leakage detectors 14. The cleaning liquid overflowing from the nozzle 3 will be collected by the nozzle leakage receiving plate 13, and the cleaning liquid overflowing from the barrel body 1 will be collected by the barrel bottom leakage receiving plate 12. At the same time, the leakage detectors 14 provided on the barrel bottom leakage receiving plate 12 and the nozzle leakage receiving plate 13 will trigger the equipment alarm after detecting leakage.

[0037] like Figure 1 As shown, a base 16 is provided on one side of the barrel bottom leakage receiving plate 12, and a slide rail 15 is provided on the base 16. The barrel bottom leakage receiving plate 12 is slidably set on the base 16 through the slide rail 15. By pushing the barrel body 1, the barrel bottom leakage receiving plate 12 can be driven to slide on the base 16.

[0038] like Figure 1 As shown, a push-pull handrail 17 is fixedly provided on the outer side of the barrel body 1 to facilitate the movement of the barrel body 1.

[0039] During the specific implementation of this embodiment, the operator first pulls out the barrel body 1 by holding the push-pull handle 17, opens the cover on the solution adding port 9 and adds the cleaning agent inside. After the cleaning agent reaches about two-thirds of the solution observation tube 10, the operator stops adding the cleaning agent, closes the cover on the solution adding port 9, and pushes the barrel body 1 back to complete the cleaning agent addition work.

[0040] When cleaning, move the needle to the vicinity of the nozzle 3 in advance, control the air supply device to work and supply air to the booster 5, and the booster 5 transports the cleaning liquid inside the barrel body 1 to the nozzle 3 through the supply pipe 4. Then the nozzle 3 sprays the cleaning liquid outward (the spraying height is 3-8mm) and completes the cleaning of the needle. At the same time, the excess cleaning liquid overflowing the nozzle 3 will flow back to the interior of the barrel body 1 through the solution reflux pipe 6.

[0041] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
